Description

Angle positioning fixture

Technical Field

The utility model relates to the technical field of mold processing, in particular to an angle positioning fixture.

Background Art

In the mold industry, parts with slopes are common. The ejection mechanism and slider mechanism used in the ejection system usually need to use the inclined surface to achieve the change of force direction, which is similar to the principle of the inclined wedge mechanism. The inclined surface processing of the inclined top, the inclined pressure surface of the slider, the fine inclined hole of the mold frame AB plate and other structures all need to process the inclined surface structure. At present, in the processing process, the commonly used clamping scheme is to clamp the workpiece with a batch clamp, and then use the dial indicator to calibrate the workpiece to calculate the slope, so as to determine the slope of the workpiece; or the angle suction cup sucks the workpiece, and then calculates the slope of the workpiece through the dial indicator calibration method, so as to determine the slope of the workpiece. Since the existing methods need to use the dial indicator calibration to adjust the angle accuracy, the working time is long and the efficiency is low. There is also a risk of workpiece displacement (offset) during calibration, resulting in errors in dimensional accuracy.

Please refer to FIG. 1 , an embodiment of the present invention provides an angle positioning fixture, including: a base 10 , a workbench 20 and an angle adjustment block 30 .

Please refer to Figure 2. The workbench 20 is rotatably matched with the base 10. A support portion 21 is formed on the top of the workbench 20. The support portion 21 is used to support the workpiece 40. A magnetic attraction structure (not shown) is provided in the workbench 20. The magnetic attraction structure is used to adsorb the workpiece 40 on the support portion 21 to clamp the workpiece 40. The clamping is fast and convenient.

The workbench 20 may be a magnetic structure as a whole, for example, the workbench 20 is a magnet as a whole, or a magnetic structure is provided inside the workbench 20, for example, a magnet is installed inside the workbench 20. Magnetic attraction can quickly absorb the workpiece 40, is suitable for positioning parts with straight edges, and improves positioning efficiency.

The angle adjustment block 30 is detachably disposed on the base 10 and supported on the bottom of the workbench 20 so that the support portion 21 is inclined at a preset angle.

Please refer to FIG. 3 and FIG. 4 . A processing structure 41 is provided on the workpiece 40. The processing structure 41 needs to be vertically oriented to a specific angle to be processed. For example, in this embodiment, the processing structure 41 needs to be vertically upward. However, the processing structure 41 and the extension direction of the workpiece 40 form an acute angle greater than 0° and less than 90°, which requires the workpiece 40 to be tilted so that the processing structure 41 can be vertically upward. The workbench 20 is supported by the angle adjustment block 30, so that the workbench 20 is maintained at a specific angle, so that the workpiece 40 is placed on the support portion 21, the workpiece 40 is in an inclined posture, and the processing structure 41 can be vertically upward. The angle adjustment block 30 can be designed according to actual processing requirements. For example, in this embodiment, angle adjustment blocks 30 of different heights are pre-designed so that the support portion 21 of the workbench 20 is at different angles relative to the horizontal plane. For example, the support portion 21 of the workbench 20 is at an angle of 8°, 10° or 5° relative to the horizontal plane.

In some optional embodiments, a protruding positioning piece 22 is provided at the bottom of the workbench 20, and a positioning groove 31 is provided on the angle adjustment block 30.

In some optional embodiments, the bottom of the positioning groove 31 is supported on the bottom of the positioning member 22 and is parallel to the support portion 21. The bottom of the positioning groove 31 is designed to adapt to the angle of the workbench 20 so that the pressure of the positioning member 22 acts vertically on the bottom of the positioning groove 31, thereby preventing the positioning member 22 from sliding relative to the positioning groove 31, making the bottom of the positioning groove 31 more stable in supporting the workbench 20 and more balanced in force.

In some optional embodiments, the vertical cross-section of the positioning member 22 is circular, and the inner walls of the positioning groove 31 on opposite sides of the positioning member 22 gradually approach each other in the downward direction.

The limiting portion 32 cooperates with the limiting groove 11 to realize the detachable assembly of the angle adjustment block 30 and the base 10. The limiting groove 11 limits the horizontal movement of the angle adjustment block 30, thereby facilitating the rapid replacement of the angle adjustment block 30.

The rotational cooperation mode of the workbench 20 and the base 10 can be designed according to actual needs. For example, in some optional embodiments, the workbench 20 is rotationally cooperated with the base 10 via the rotation shaft 23.

In order to facilitate the stable installation of the rotating shaft 23, in some optional embodiments, two mounting seats 12 and two cover plates 13 are provided on the base 10. The two mounting seats 12 are respectively located on both sides of the workbench 20. The cover plates 13 are correspondingly arranged on the mounting seats 12 and are surrounded by the mounting seats 12 to form a rotating shaft hole 14. The rotating shaft 23 is passed through the two rotating shaft holes 14. The rotating shaft 23 can rotate relative to the rotating shaft hole 14, thereby realizing the rotation of the workbench 20 relative to the base 10.

The installation method of the cover 13 can be designed according to actual needs. For example, in order to facilitate production and assembly, in some optional embodiments, the cover 13 has a threaded structure or a snap-on structure to achieve detachable assembly with the mounting base 12.
