Description

Technical Field

[0001] This utility model belongs to the technical field of coil shaping fixtures, specifically relating to a shaping fixture for linear motor coils. Background Technology

[0002] In the field of linear motor manufacturing, coreless coils, lacking a core for positioning, require shaping using a forming fixture (such as CN119483149A). The entire fixture is then placed in an oven for curing to form a single coil from the copper wire. After curing, removing the cover plate of the forming fixture presents several challenges. Firstly, the existing fixtures use screws to fix the cover plate to the base. This requires unscrewing each screw individually, resulting in low efficiency, reduced production, and a high risk of screw loss. Secondly, the lifting force of the return spring during screw removal creates a continuous force between the cover plate and the base. Especially when the last few screws are about to be removed, this lifting force can cause the cover plate and screw holes to crack, resulting in structural damage to the fixture. Furthermore, the fragments could injure operators, posing a safety hazard. Utility Model Content

Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] A shaping fixture for linear motor coils, see [link / reference] Figure 1 It includes a base 100, a wire fixing plate 200, a pressure plate assembly 300, and a fixing assembly 400. The top of the base 100 has a receiving groove 110, which extends through the base 100 along its length. Figure 2 As shown, the receiving groove 110 is a stepped groove. A lifting assembly is provided at the bottom of the receiving groove 110. A wire-fixing plate 200 is disposed within the receiving groove 110, with its two long sides engaging with the bottom of the receiving groove 110 to allow it to be secured within the receiving groove 110. The bottom surface of the wire-fixing plate 200 is pressed against the lifting assembly, allowing it to be lifted in normal operation, thus facilitating the removal of the coil 700 after curing. A pressure plate assembly 300 is disposed on the base 100 and covers the receiving groove 110; the bottom of the pressure plate assembly 300 is used to press the coil.

[0018] This embodiment has multiple fixing components 400, with at least two fixing components 400 provided on opposite sides of the shaping fixture. Taking one fixing component 400 as an example, see... Figures 3-4The fixing assembly 400 includes a first connecting seat 410, a second connecting seat 420, a handle 430, and a fastener 440. The first connecting seat 410 is connected to the side wall of the pressure plate assembly 300, and the second connecting seat 420 is connected to the side wall of the base 100 and is disposed opposite to the first connecting seat. The first connecting seat 410 is provided with a fastening part 412; the top end of the handle 430 is hinged to the top end of the second connecting seat 420, the hinge axis of the hinge is parallel to the mounting surface of the second connecting seat 420, and the bottom end of the handle 430 is an operating part 431. One end of the fastener 440 is hinged to the middle position of the handle 430, and the other end of the fastener 440 is fastened to the fastening part 412.

[0019] When it is necessary to fix the pressure plate assembly 300 to the base 100, turn the handle 430 upward so that the fastener 440 can be fastened to the fastening part 412 of the first connecting seat 410. Then turn the handle 430 downward so that the fastener 440 can be tightly fastened to the fastening part 412, and finally fix the pressure plate assembly 300 to the base 100. After the pressure plate assembly 300 is fixed, place the entire fixture in the oven to cure the coil. When removing the coil after curing, the operator can perform operations including but not limited to the following: press the pressure plate assembly 300 with the thumb, and use the remaining four fingers of the left hand and the remaining four fingers of the right hand to flip up the handles 430 of the fixing components 400 on the opposite sides.

The bottom of the T-shaped substrate 411 is bent upward to form a fastening part 412. The structure of the first connecting seat 410 is simple and easy to process.

[0024] With the pressure plate assembly 300 fixed to the base 100, the fastening part 412 is located on the top outer side of the base 100. To avoid interference between the fastening part 412 and the side wall of the base 100, the side wall of the base 100 is provided with a relief groove 120, which is opposite to the fastening part 412 and penetrates through the top surface of the base 100.

[0025] In this embodiment, the fastener 440 has a four-sided frame structure, which is simple and can be adapted to the fastening part 412 to achieve a fastening connection.

[0026] In this embodiment, in order for the fastener 440 to be stably fastened onto the fastening part 412, in the fastened state, the bottom of the handle 430 faces the base 100 (see...). Figure 4 When the handle 430 is tilted, it is pulled tight by the fastener 440, thus ensuring the stability and reliability of the fastening.

[0027] In this embodiment, see Figure 2 The bottom of the receiving groove 110 is provided with four evenly distributed grooves 111, each groove 111 is provided with a spring post 500, the top of the spring post 500 abuts against the bottom surface of the wire fixing plate 200, for periodically fixing the wire fixing plate 200 when the fastening is released. The spring posts 500 of the four grooves 111 form a lifting assembly.

[0028] The bottom of each groove 111 extends through to the bottom surface of the base 100 and is fixed with screws.

[0029] In this embodiment, the pressure plate assembly 300 includes a cover plate 310 and a pressure plate 320. The bottom of the cover plate 310 is provided with two pressure lines 312 along the aforementioned length direction.
