[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0020] First, combine Figures 1-6 This invention describes a plastic part positioning fixture according to an embodiment of the present invention, used for positioning a plastic housing 700, and has a wide range of applications.

[0021] like Figures 1-6 As shown, a plastic part positioning fixture according to an embodiment of the present invention includes a mounting plate 100, a fixture base film 200, a positioning block 300, and a clamping module.

[0022] like Figures 3-5As shown, the fixture base film 200 is set on the mounting plate 100, and the fixture base film 200 is provided with a positioning groove 201 for placing the plastic housing 700.

[0023] like Figures 3-6 As shown, the positioning block 300 is disposed on the positioning groove 201 and is used to cooperate with the positioning area 703 on the plastic housing 700 to position the plastic housing 700 and achieve precise positioning of the plastic housing 700.

[0024] like Figures 3-5 As shown, a clamping module is mounted on the mounting plate 100 and located on one side of the fixture base film 200, used to clamp or loosen the plastic housing 700 on the fixture base film 200. The clamping module includes a rotating unit, a pressure block 402, and a clamping element 403. The rotating unit is mounted on the mounting plate 100 and provides the driving force for rotational movement; the pressure block 402 is connected to the output end of the rotating unit; the clamping element 403 is located on the pressure block 402. When the plastic housing 700 is placed into the positioning groove 201 on the fixture base film 200, the rotating unit drives the pressure block 402 and the clamping element 403 to rotate, thereby clamping the plastic housing 700.

[0025] Furthermore, in this embodiment, the clamping element 403 is urethane.

[0026] Furthermore, such as Figures 3-5 As shown, the rotating unit includes a fixed frame 4011 and a rotating cylinder 4012. The fixed frame 4011 is mounted on the mounting plate 100; the rotating cylinder 4012 is mounted on the fixed frame 4011, and the output end of the rotating cylinder 4012 is connected to the pressure block 402. By controlling the operation of the rotating cylinder 4012, the pressure block 402 can be driven to rotate.

[0027] Furthermore, such as Figures 3-5 As shown, the rotating unit also includes a first reinforcing rib 4013, which connects the fixing frame 4011 and the mounting plate 100 to improve the connection strength and ensure the stability of the fixture.

[0028] Furthermore, such as Figures 3-5 As shown, a plastic part positioning fixture according to an embodiment of this utility model further includes: four uprights 501 and a base plate 502. The four uprights 501 are disposed at the four bottom corners of the mounting plate 100; the base plate 502 is disposed at the bottom of the four uprights 501. Through the arrangement of the mounting plate 100, the four uprights 501 and the base plate 502, the height requirements of the fixture base film 200 and its installation and fixation are achieved.

[0029] Furthermore, such as Figures 3-5As shown, a plastic part positioning fixture according to an embodiment of the present invention further includes: a second reinforcing rib 600, which connects the fixture bottom film 200 and the mounting plate 100 to improve the connection strength and ensure the stability of the fixture.

[0030] Place the plastic housing 700 into the positioning groove 201 on the base film 200 of the fixture, and align the positioning area 703 on the plastic housing 700 with the positioning block 300. Then control the rotary cylinder 4012 to drive the pressure block 402 and the clamping part 403 to rotate, thereby clamping the plastic housing 700 and completing the preparation before the hot melt embedding of the copper nut 800, waiting for the hot melt embedding of the copper nut 800.

[0031] Above, refer to Figures 1-6 This invention describes a plastic part positioning fixture according to an embodiment of the present invention. The fixture is custom-designed and can accurately position the plastic housing 700, ensuring the accurate hot-melt embedding of the copper nut 800, as well as the precision and consistency of the production process.
