Description

Technical area

The present invention relates to the technical field of vehicle maintenance, especially a 3D 4-wheel positioning machine.

background

According to technical specifications for vehicles, the tires must meet the requirements for certain angles after assembly on vehicles. The key angles are toe angle, camber angle, interior angle of the master screw, and exterior angle of the master screw. After the vehicle has been used for a certain period of time, the parameters change, which affect the function of the vehicle. Thus, new measurement and adjustment are required for the vehicle. The gauge is a 4-wheel positioning machine. The 3D 4-wheel positioning machine concerns a new measuring technology. By analysis of the images and calculation by a computer, a three-dimensional coordination is to be created. Thus, the parameters of the positioning of the tires are to be expected.

It is known that a static measurement at 2 points is used for current 3D 4-wheel positioning machine. Static images are to be taken for a position of the vehicles by camera. Then the vehicle is to be moved a certain distance to take static pictures of other positions. Thereafter, three-dimensional coordinates are to be created, wherein the two positions of the vehicle represent two points in the three-dimensional coordinates.

Since the trajectory of the tires is theoretically regarded as a known fluctuation line, the trajectory is therefore theoretically calculated from the two points and angles of rotation. Then the parameters of the positioning of the tires are derived from the track. This measurement can be calculated only after 2 points and an angle certain track of the tires analogously. If deviation is to occur at the two points or the angle or difference between both reference surfaces of the two points caused by non-flat space or fluctuation from the place or not exact angle, the analogue calculated track may deviate from the actual track, so that the measurement accuracy is disadvantaged becomes. In addition, turning by a certain angle and possible accuracy of the position of the vehicle's stance are required, thus increasing the difficulty of operation, extending working time and reducing work performance.

To solve the above problems, a 3D 4-wheel positioning device is disclosed in the Chinese Patent CN I02735457A comprising rail space, 4 reflection targets attached to tires, industrial camera mounted on both sides of the support for collecting the images, lighting on the front side, and drive plate and main unit in the center of the support. The carrier is directed perpendicular to the central axis in the longitudinal direction of the vehicle. The center of the carrier is in the middle of the axle of the vehicle. The main unit includes control and output. Data cable connects a camera to the main unit.

However, the technique of the above-mentioned patent involves many problems. For example, the too large dimension of the carrier and the whole system caused by placement of the main unit in the center of the carrier, which is not friendly to people. In addition, movement from the rail space is substantially limited due to the attachment of the carrier. Exceeding the range of the camera is possible. The adjustment is labor-intensive and the work performance is thus low.

Content of the invention

The present invention aims at solving the problems of the current technology and offers a 3D 4-wheel positioning machine which can perform a function of automatically tracking the targets and moving up and down, respectively.

For such goals the following techniques according to the invention are used:
A 3D 4-wheel positioning machine includes the rail space, 4 reflection targets attached to tires, the carrier, and industrial camera mounted on both sides of the carrier to collect the images and main unit, column, and lifting frame for movement along the column by drive. Said carrier is fixed to the lifting frame, with a rack is attached to the column. On said frame, a gear corresponding to the rack and motor for driving said gear is mounted.

The machine also includes a Gengengewichtsteil which includes fixed roller above said rack and a steel cable for connection between the counterweight part and the lifting frame. The steel cable turns around the fixed roller.

At the said column upper hammer and lower hammer are attached to the stroke of the lifting frame.

Said lifting frame comprises a bearing plate for supporting the motor and the rack. Thus, a side plate is formed on both sides of the bearing plate and bottom plate on the front side of the side plate, which is bent vertically inwardly. Said bearing plate, side plate and bottom plate receive the column to allow coupling between the gear and the rack.

Between the bearing plate and bottom plate, a roller made of nylon is rotatably arranged. Said roller comprises a rod and a disc on one side of the rod. The said rod is located on the side of the column and the disc is placed between the base plate and the column.

The column and the carrier are made of aluminum.

Compared to the current technology, the present invention has the following advantages:
In the 4-wheel positioning machine according to the invention, the carrier can move up or down against the column. This enhances its usability, extending the scope of hiring and hiring. In addition, after analyzing the captured images by the mainframe, the movement of the wearer up or down can be controlled to ensure that the 4 targets are in the field of view of the camera. In addition to facilitating manual adjustments, intelligence is made possible by the product.

Concrete execution

The invention is to be further described with reference to the figures and exemplary embodiments. The embodiments are only to be considered as a description of the invention. The invention should therefore not be limited by the specific embodiments.

As and shown that the inventive 3D 4-wheel positioning machine the rail space, 4 Reflection targets attached to tires, the carrier, and industrial camera mounted on both sides of the carrier for collecting the images, main unit, column 1 as well as lifting frame 2 for movement along the column by drive. The named carrier (not shown in Fig.) Is with the lifting frame 2 attached, with rack 11 attached to the column. On said frame gear (not shown in Fig.) According to the rack and motor for driving said gear attached. Of these, the rail space, the reflection targets and the industrial camera correspond to the current techniques, which will not be described further here. The main unit is arranged separately from the carrier, so that the adjustment of the main unit is facilitated and the friendliness is increased. At the same time, the dimension of the column and the carrier is reduced, so that the space and materials consumption are reduced. Alu can be used for the carrier and the column. In addition to the strength of small weight of the carrier and the whole device is possible.

It is advantageous if smaller speed drop motor is used as the inventive motor, which has small size and stable operation. In addition to functional performance, the dimension is reduced as much as possible.

To reduce load on the engine, the counterweight part is made for the invention. The counterweight portion comprises the fixed roller, counterweight and the steel cable for connection between the counterweight and the lifting frame mounted above said rack, the cable rotating about the fixed roller. The mass of the counterweight corresponds to the total mass of the lifting frame and carrier. Thus, lowering of the load of the motor is enabled, allowing the smaller size, higher power and low power consumption.

In addition, on the column also an upper hammer 12 and lower hammer 13 be attached to the stroke of the lifting frame. With the upper and lower hammer it can be ensured that the lifting frame is within the adjustment range to avoid mistakes.

The side plate 22 on the two sides of the bearing plate and on the front of the side plate 22 and inwardly vertically curved bottom plate 23 are formed. The bearing plate, side plate and bottom plate are arranged around the pillar to secure connection between gear and rack. Between the bearing plate and bottom plate is a roller 24 made of nylon rotatable. Said roller comprises a rod and a disc on one side of the rod. The said rod is located on the side of the column and the disc is placed between the base plate and the column. The said rod on both sides partially holds the column. The disc of nylon rod is partially between the side of the Column and bottom plate of the lifting frame held so that the direct contact between the column and lifting frame is avoided, ie that a rod of nylon at the front and rear ends of the two sides of the lifting frame is arranged as a roller contact. The T-section roller allows for contact between the side, bottom plate and pillar. Roller contact improves friction between the lifting frame and the column This optimizes the stable drive and load of the motor.

Furthermore, mounting plate 25 and protective cap 26 The motor is arranged on the bearing plate to ensure stability and safety. Such plates also take over the connection between the main unit and the camera. They allow the control of the engine, improve the heat conduction and increase the stability. The protective cap 26 the motor and the gear are integrated therein, avoiding the influence from the outside and ensuring stable movement of the carrier.

In the inventive 3D 4-wheel positioning automatic movement of the carrier is made upwards or downwards against the column, so that the usability is enhanced and scope of the setting and the height are extended. In addition, after analyzing the captured images by the mainframe, the movement of the wearer up or down can be controlled to ensure that the 4 targets are in the field of view of the camera. In addition to facilitating manual adjustments, intelligence is made possible by the product.
