Detailed Implementation

[0017] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0018] like Figures 1 to 5 As shown, the present invention provides a fixture for a non-standard workpiece 6, including a base 1, a pressing module 2, a support 3, a stop block 4, and a limiting module 5, all disposed on the base 1. The support 3 is used to support the non-standard workpiece 6. The stop block 4 and the limiting module 5 are respectively located on both sides of the support 3. The top of the support 3 is provided with a receiving groove 31 adapted to the non-standard workpiece 6. The limiting module 5 is used to force the non-standard workpiece 6 to abut against the stop block 4. The pressing module 2 is used to press and position the non-standard workpiece 6 onto the support 3.

[0019] like Figure 1The irregularly shaped workpiece 6 shown has a frame 61 and a protruding ridge 64 at the top, and a pivot 62 at the bottom. When it is necessary to process the pivot 62 at the bottom, this utility model is used to fix it. Specifically, the irregularly shaped workpiece 6 is placed on the support member 3 with its bottom facing upward, so that the support member is located between the two frames 61, and the protruding ridge 64 is accommodated in the receiving groove 31; then the limiting module 5 is used to push the irregularly shaped workpiece 6 towards the stop block 4; until the irregularly shaped workpiece 6 is in close contact with the stop block 4, the pressing module 2 is used to press the irregularly shaped workpiece 6 at the position between the two frames 61, thereby completing the fixation of the irregularly shaped workpiece 6.

[0020] Since the irregular workpiece 6 has a frame 61 and a rotating shaft 62, it is relatively difficult to fix it. Therefore, this utility model cleverly sets up a receiving groove 31 and a pressing module 2 to adapt to the structure of the frame 61 and the rotating shaft 62 respectively, so as to achieve reliable clamping and fixing of the irregular workpiece 6, thereby facilitating subsequent processing.

[0021] In this embodiment, a limiting post 32 is provided at the top of the support member 3. The limiting post 32 is used to insert into the hole / groove of the irregular workpiece 6. The irregular workpiece 6 actually has a clearance hole 63 for subsequent assembly. This utility model utilizes the cooperation between the limiting post 32 and the clearance hole 63 to achieve the effects of guidance and positioning, ensuring that the support member 3 is easy to align when installed in this utility model, thereby making the clamping action more convenient.

[0022] In this embodiment, the stop block 4 is fixed to one side of the support member 3 by screws, so that the stop block 4 can be replaced and adjusted as needed.

[0023] In this embodiment, the pressing module 2 includes a pressing cylinder 21 and a pressing block 22. The base 1 is provided with a through hole 11. The pressing cylinder 21 is installed at the bottom of the base 1. The piston rod of the pressing cylinder 21 passes through the through hole 11 and protrudes to the top of the base 1. The pressing block 22 is installed on the piston rod of the pressing cylinder 21.

[0024] That is, the base 1 of this utility model is actually a plate. The pressing cylinder 21 uses the space at the bottom of the base 1 for assembly and fixation, so that the space at the top of the base 1 is made more fully utilized. At the same time, when a larger pressing force is required, the pressing cylinder 21 set at the bottom is larger in volume and will not interfere with the installation and operation of the components at the top of the base 1.

[0025] The pressure block 22 is pressed between the two rotating shafts 62, which makes the pressing more stable.

[0026] Specifically, the pressing module 2 also includes a limiting seat 23 detachably disposed on the base 1. The top of the limiting seat 23 is provided with a limiting groove. One end of the pressing block 22 is used to press the irregular workpiece 6, and the other end of the pressing block 22 is movably disposed in the limiting groove.

[0027] The limiting seat 23 guides the lifting and lowering of the pressure block 22, allowing the pressure block 22 to rise and fall along a straight line as much as possible, so as to avoid misalignment and ensure reliable clamping of the irregular workpiece 6.

[0028] Specifically, one end of the pressure block 22 is connected to the pressure holding cylinder 21, and the other end of the pressure block 22 is provided with a relief groove 24. A pressure holding member 25 is installed in the relief groove 24, and the shape of the pressure holding member 25 is adapted to the top shape of the irregular workpiece 6.

[0029] The clamping member 25 is fixed to the pressure block 22 by screws. When the clamping member 25 deforms after a certain period of use, or when the irregular workpiece 6 to be clamped needs to be replaced, the clamping member 25 can be replaced to adjust the situation, thereby improving the flexibility of this utility model.

[0030] It should be noted that the limiting module 5 of this utility model includes a limiting cylinder 51 and a limiting abutment block 52 disposed on the piston rod of the limiting cylinder 51. The limiting cylinder 51 drives the limiting abutment block 52 to move back and forth, so that the limiting abutment block 52 pushes the irregular workpiece 6 to contact the stop block 4, thereby achieving the effect of clamping the irregular workpiece 6 from the side.

[0031] The limiting abutment block 52 is preferably the protruding edge 64 that abuts the irregular workpiece 6, so that the contact area between the limiting abutment block 52 and the irregular workpiece 6 is smaller, thereby increasing the pressure and improving the stability of clamping.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
