Electronic four stations rotation wrist

Technical field

The utility model relates to the auxiliary equipment in the machining, particularly a kind of electronic four stations rotation wrist.

Background technology

In the modern industrialization production process; It is very limited enhancing productivity through the performance that improves production equipment merely; And the intervention of automation auxiliary equipment; Can the mankind be freed from the numerous and diverse manual labor of dullness on the one hand, have only the industrialization of realization fully-automatic production on the other hand, be only the final solution of enhancing productivity and improving.

One of key technology of in mechanical processing process, enhancing productivity is to realize the function of automatic loading/unloading, and in each manufacturing procedure and in the logistics different placement attitudes is arranged automatically, wherein the most general position relation is exchanging of vertical, horizontal level like part.The truss manipulator mainly is made up of transverse axis, vertical pivot, wrist, paw, can realize that the vertical up and down of part position moves and horizontally rotate.Because the truss-like manipulator has simple in structure, easy to maintenance, processing ease, high performance-price ratio and to advantages such as the machine reformation amount are little; Mechanical processing industry is promoted rapidly at home just gradually; But this type of present manipulator is owing to can only realize the conversion of two stations of horizontal level; Promptly 0 ° → 90 ° or 0 ° → 180 ° or 0 ° → 270 ° rotations have restricted the user demand of truss-like manipulator to a certain extent.And can realize 0 ° → 90 ° → 180 ° three stations and four station manipulators of 0 ° → 90 ° → 180 ° → 270 ° of rotations; Mainly be to adopt import; And structure is very complicated, cost an arm and a leg, and physical dimension is all solidified simultaneously, and the integral body that is not easy to domestic existing equipment is arranged and installed.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned existing in prior technology defective, and the electronic four stations rotation wrist that a kind of versatility is good, simple and reliable for structure, cost is low is provided.

The utility model is realized through following skill scheme: a kind of electronic four stations rotation wrist; Comprise electrical control gear, frame, rack-mounted rotatable wrist; It is characterized in that above-mentioned wrist by rotatable rack-mounted output shaft be fixed on discoid positioning disk, follower and transposition on the output shaft dish of issuing an order and form; On the circumference of discoid positioning disk, be uniformly distributed with and have 4 " U " shape locating slots, the alignment pin that matches with " U " shape locating slot is installed in the piston rod end in the positional cylinder, and positional cylinder is fixed on the frame; Rack-mounted position sensor and transposition are issued an order to coil and are matched; Driving wheel is fixed on the motor output shaft of band decelerator, and cog belt or chain are installed between driving wheel and the follower, is fixed with the terminal pad that is used to install paw at an end of output shaft.

Above-mentioned positional cylinder is cylinder or oil cylinder.Above-mentioned position sensor is two.

The magnetic valve that the motor of above-mentioned band decelerator, position sensor and control positional cylinder move is all controlled through electrical control gear.

The utlity model has following characteristics: this device rotates in 0 ° of-270 ° of scope through the driven by motor output shaft; Simultaneously on output shaft, installed the discoid positioning disk that can be accurately 0 °, 90 °, 180 °, 270 ° four positions be positioned and with the supporting alignment pin of positioning disk; So just can realize the accurate location of four stations; Through position sensor and the associated transposition dish of issuing an order, can realize the location of four stations, the close fit and the transposition rapidly of switching simultaneously.Issue an order through position sensor and associated transposition simultaneously and coil and electrical control gear, just can realize rapid location, switching and the transposition of four stations, utilize two position sensors to respond to the phase change of issuing an order and coiling simultaneously, tell four phase places of wrist.Two sensors are formed four composite signals according to sense state: 00,01,11,10; Four unique positions of four corresponding wrists of composite signal difference.Rotation is divided into: forward single action, reverse single action and leap are rotated, concrete relation such as following table of rotating;

In the last table, ↑: 90 ° of single step main storys, ↓: 90 ° of single step counter-rotatings, ↑ ↑: just changeing promptly 180 ° of 2 positions, ↓ ↓: two positions of reversing are-180 °, ↑ ↑ ↑: promptly 270 ° of 3 positions of main story, ↓ ↓ ↓: two positions of reversing are-270 °.Dish is installed in output shaft because location, transposition are issued an order; The terminal pad that is used to install paw simultaneously is installed in an end of output shaft; Characteristics such as it is simple and reliable for structure that this wrist is had, and cost is low, volume is little, the installation adjustment is simple, be easy to safeguard, light, attractive in appearance.

Description of drawings

Accompanying drawing 1 is the structural representation after locate 0 ° of position of the utility model;

Accompanying drawing 2 is 45 ° of structural representations of the utility model rotation.

The specific embodiment

As shown in Figure 1, be installed with the motor 12 of being with decelerator in the upper end of frame 3, on the output shaft 2 of the motor of being with decelerator, be installed with driving wheel 1.The rotatable output shaft 10 that is equipped with in the lower end of frame is installed with discoid positioning disk 7, follower 9 and the transposition dish 8 of issuing an order on output shaft, cog belt 11 is installed between driving wheel and the follower.On the circumference of discoid positioning disk, be uniformly distributed with and have 4 " U " shape locating slots, the alignment pin 5 that matches with " U " shape locating slot is installed in the piston rod end in the positional cylinder 4, and positional cylinder 4 is fixed on the frame.Position sensor 6 is installed in frame, and matches with the transposition dish of issuing an order, and is fixed with the terminal pad that is used to install paw at an end of output shaft.
