Description

Technical Field

[0001] The utility model belongs to the technical field of parts processing, and in particular relates to a positioning tool used for parts processing. Background Art

[0002] When parts are being processed by tooling, positioning tooling is needed to clamp the parts to facilitate the operation of the staff.

[0003] The positioning tooling currently on the market has the problem of needing to replace different types of fixtures according to the different types and specifications of parts during the processing of parts, which easily leads to the problem of increasing the purchase cost of positioning tooling.

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the following is a detailed description of the embodiment and the attached drawings. Figure 1-2 , the utility model is further described in detail. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] The utility model provides a positioning tool for parts processing, comprising a work support platform 11, wherein the work support platform 11 comprises four support legs 5, and the bottom of the support legs 5 is screwed with an adjustment pad 9. The arrangement of the adjustment pad 9 can facilitate the adjustment of the height of the four support legs 5, and can always keep the work support platform 11 stable when encountering an uneven ground.

[0021] The work support table 11 is provided with a plurality of positioning units, each of which is slidably mounted in a corresponding sliding groove 7 on the work support table 11, two sliding grooves 7 arranged in a forward staggered manner form a group, and the work support table 11 is provided with at least one group of sliding grooves 7, and a plurality of groups of sliding grooves 7 are uniformly rotated and arranged on the work support table 11 with the center of the work support table 11 as the center of the circle. The staggered sliding grooves 7 can leave their center positions vacant, which is convenient for processing the center positions of parts.

[0022] The driving block 8 of the positioning unit passes through the sliding groove 7 and is connected to the driving assembly, and the driving assembly includes a driving motor 10, and the driving motor 10 drives the screw rod 6 to rotate, and the driving block 6 is correspondingly installed on the screw rod 6. The driving motor 10 drives the driving block 6 to move in the sliding groove 7 through the rotation of the screw rod 6, thereby driving the positioning unit to move on the working support table 11, which is suitable for processing parts of different sizes.

[0023] The positioning unit includes a positioning column, and the positioning column includes a lower positioning column 12 connected to the driving block 8, and an upper positioning column 16 is installed on the lower positioning column 12 through damping rotation. A detachably installed side positioning plate 3 is provided on the inner side of the positioning column. The lower positioning column 12 can be damped and rotated on the upper positioning column 16. When the upper positioning plate 1 is needed for positioning, the upper positioning plate 1 is rotated to the upper end of the part; when the upper positioning plate 1 is not needed for upper side positioning, the upper positioning plate 1 is rotated to the end away from the part to facilitate the placement of the part.

[0024] The upper positioning column 16 is provided with a mounting groove, and a positioning screw 13 is rotatably provided in the mounting groove. A corresponding moving block 14 is installed on the positioning screw 13, and the inner side of the moving block 14 is connected to the upper positioning plate 1. The lower end of the upper positioning plate 1 is provided with a buffer wear pad 4, and the setting of the buffer wear pad 4 can prevent the parts from being worn when the upper positioning plate 1 is pressed down. The positioning screw 13 is connected to the positioning drive motor 15. The positioning drive motor 15 drives the positioning screw 13 to rotate so that the moving block 14 drives the upper positioning plate 1 to move up and down, thereby achieving the clamping and positioning of the parts, and can also be applied to parts of different heights, with strong applicability.

[0025] A mounting base 2 is provided on the inner side of the lower positioning column 12, and the mounting base 2 is connected to the side positioning plate 3 by bolts, and a buffer wear-resistant pad 4 is provided on the inner side of the side positioning plate 3. The side positioning plate 3 is detachably mounted on the mounting base 2, and when the part is a special-shaped part, the side positioning plate can be replaced with a matching side positioning plate.

[0026] The utility model can vacate the center position of the part for easy processing through the offset sliding groove and positioning unit, while ensuring the stability of clamping and improving the accuracy of processing. The side positioning plate of the positioning unit can move laterally and the upper positioning plate of the positioning unit can move up and down, which can meet the processing needs of parts of different sizes and reduce processing costs.
