[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] Please see Figures 1 to 3This utility model provides an embodiment of a positioning fixture, comprising two clamping blocks 1 and a base 2 that are fitted together. The base 2 has receiving grooves 3 on both sides that are adapted to the shape of the clamping blocks 1. The two clamping blocks 1 are respectively inserted into the receiving grooves 3. Each clamping block 1 has several top contacts 4. The base 2 also has several longitudinally penetrating adjustment holes 5. Each adjustment hole 5 on any side is connected to the receiving groove 3 on the corresponding side. The several top contacts 4 are inserted from the side into the several adjustment holes 5. After the hardware part is inserted into the adjustment hole 5, the clamping block 5 presses inward, meaning the top contacts 4 can clamp the hardware part, achieving a clamping effect. Since the number and position of the several top contacts 4 and the several adjustment holes 5 are matched, multiple parts can be clamped simultaneously, allowing for the simultaneous processing of multiple hardware parts and improving processing efficiency.

[0019] At least two cylindrical grooves 6 are provided in the receiving groove 3. A spring 7 is installed in each cylindrical groove 6. One end of the spring 7 abuts against the inner end of the cylindrical groove 6, and the other end of the spring 7 abuts against the corresponding clamping block 1. That is, when the hardware part does not need to be clamped, the elastic force of the spring 7 can push the clamping block 1 outwards, and the contact point 4 moves outwards towards the adjustment hole 5, releasing the clamping action and facilitating the placement of the next part into the adjustment hole 5. The clamping block 1 includes a first clamping block 1a and a second clamping block 1b. The first clamping block 1a has a transversely penetrating guide hole 8, and the inner end of the second clamping block 1b has a threaded hole 9. A screw 10 is also provided in the base 2. The threaded end of screw 10 passes through the guide hole 8 and is threaded into the threaded hole 9. The large end of screw 10 abuts against the outer side of the first clamping block 1a. By rotating screw 10, the threaded end of screw 10 is driven relative to the second clamping block 1b. This can control the first clamping block 1a and the second clamping block 1b to move closer or further apart. When the first clamping block 1a and the second clamping block 1b move closer together, the top contact 4 moves to the center side and clamps with the adjusting hole 5. When the first clamping block 1a and the second clamping block 1b move further apart, the clamping block 1 moves outward to achieve the unfolding action, releasing the clamped hardware and making it convenient to remove and place the next hardware.

[0020] In this embodiment, the clamping blocks 1 are all convex in shape, with the top joints 4 located at the sharp corners of the clamping blocks 1; and the top joints 4 are provided with sloping top surfaces 11, which can be adapted to cylindrical parts to make their clamping effect better.

[0021] The base 2 has standard holes 12 running longitudinally through its four corners. The four standard holes 12 and several adjustment holes 5 are arranged in an "X" shape. The standard holes 12 are used to compare the dimensions of standard parts.

[0022] In this embodiment, there are four adjustment holes 5, and the hole diameters of the adjustment holes 5 are different, which can improve the versatility of the positioning fixture and allow it to clamp parts of more sizes.

[0023] Several adjustment holes 5 are fitted with abutment rings 13. The abutment rings 13 are mainly adapted to the curved surface of the cylindrical parts to improve their clamping effect.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
