Description

Technical Field

[0001] This invention relates to the field of linear motor technology, and in particular to a linear motor coil lead bending device. Background Technology

[0002] A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It is widely used in transportation, machinery, and instrumentation industries, possessing characteristics such as high speed, high acceleration, and high precision, and has excellent application and development prospects. During the manufacturing process of a linear motor, the coil leads need to undergo certain bending treatments to meet the requirements of coil embedding and welding between coils.

[0003] However, as Figure 1 As shown, the wire gauge of linear motors is thicker than that of other rail transit motors, with more coils wound in parallel and a relatively larger number of lead wires. The original shuttle-shaped coil lead wire bending method cannot meet the mass production requirements of linear motors. Manual bending with tools is inefficient, difficult, and makes it hard to ensure the consistency of coil lead wire bending. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a linear motor coil lead bending device that is simple to operate, has high bending efficiency, and good bending quality.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A linear motor coil lead bending device includes a base, on which are provided a pull mechanism for pulling a suspended coil and two bending mechanisms for bending the coil lead, the two bending mechanisms being located on both sides of the pull mechanism.

[0007] As a further improvement to the above technical solution:

[0008] The pull mechanism includes a fixed socket and a movable socket for respectively connecting the two ends of the coil. The fixed socket is fixed on the base, and the movable socket is slidably mounted on the base. The base is provided with a driving component for sliding the movable socket relative to the fixed socket.

[0009] The drive assembly includes a first support, a second support, a pull rod, a connecting rod, and a handle. The first support and the second support are fixedly mounted on the base at intervals. The handle is slidably mounted on the first support. One end of the handle is hinged to the second support. One end of the connecting rod is hinged to the middle of the handle, and the other end is hinged to one end of the pull rod. The other end of the pull rod is connected to a movable sleeve seat.

[0010] The first support is provided with a guide sleeve, and the pull rod is slidably sleeved in the guide sleeve.

[0011] The movable socket includes a slider and a movable sleeve shaft. The slider is slidably mounted on the base, and the movable sleeve shaft is fixed to one side of the slider.

[0012] The base is provided with a guide rail, and the slider is slidably mounted on the guide rail.

[0013] The fixed socket includes a fixed block and a fixed sleeve shaft. The fixed block is fixed on the base, and the fixed sleeve shaft is fixed on one side of the fixed block and is arranged opposite to the movable sleeve shaft.

[0014] The pull rod is threadedly connected to the movable sleeve seat.

[0015] The bending mechanism includes a slide block and a wrench. The slide block is slidably mounted on a base. The wrench includes a bending operation block and a rotating handle fixed to the bending operation block. The bending operation block is provided with a bending post and two limiting strips. The two limiting strips are located on both sides of the bending post, and a passage gap is formed between the limiting strips and the bending post for the coil lead to pass through. The top surface of the slide block is provided with a stop pin and a cylindrical template. The center of the cylindrical template is provided with a circular hole for the bending post to be inserted.

[0016] The base is provided with a pad, and the slide is slidably mounted on the pad.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] This invention relates to a linear motor coil lead bending device. In use, both ends of the coil are fitted onto a pull mechanism. The pull mechanism pulls the coil into a predetermined loop. Then, the coil lead is bent to one side via the pull mechanism 3 on one side of the coil, and to the other side via the pull mechanism 3 on the other side. This linear motor coil lead bending device, through the combined action of the pull mechanism and the bending mechanism, bends the coil lead in the desired direction. It is simple to operate, has high bending efficiency, and produces good bending quality.

[0019] This invention relates to a linear motor coil lead bending device. A handle, connecting rod, and pull rod are connected to form a crank-slider mechanism. The handle acts as a crank, and the pull rod acts as a slider. Rotation of the handle causes the pull rod to slide, thereby causing the movable socket to slide. In practical use, the two ends of the coil are fitted onto the fixed socket and the movable socket. Rotating the handle then causes the movable socket to slide away from the fixed socket, thus pulling the coil to its specified ring shape. The structure is ingeniously designed and easy to operate.

[0020] This invention relates to a linear motor coil lead bending device. During bending, firstly, the coil lead is placed between the stop pin and the cylindrical template on the slide. Then, a wrench is placed on the slide, allowing the bending pin to be inserted into the circular hole of the cylindrical template. At this point, the coil lead is positioned between the cylindrical template and the limiting strip. Finally, by rotating the lever, the bending operating block is rotated. Under the squeezing action of the limiting strip and the guiding action of the cylindrical template, the coil lead is bent in the desired direction. The device has a simple structure and is easy to operate. Attached Figure Description

Detailed Implementation

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Figures 2 to 11 An embodiment of the linear motor coil lead bending device of the present invention is shown. The linear motor coil lead bending device includes a base 1. The base 1 is provided with a pulling mechanism 3 for pulling the suspended coil 2 and two bending mechanisms 4 for bending the coil lead 21. The two bending mechanisms 4 are respectively located on both sides of the pulling mechanism 3.

[0036] In use, the two ends of coil 2 are fitted onto the pull mechanism 3. The pull action of the pull mechanism 3 brings coil 2 into a predetermined loop shape. Then, the coil lead 21 can be bent to one side using the bending mechanism 4 on one side of coil 2, and to the other side using the bending mechanism 4 on the other side. This linear motor coil lead bending device, through the combined action of the pull mechanism 3 and the bending mechanism 4, bends the coil lead 21 in the desired direction. It is simple to operate, has high bending efficiency, and produces good bending quality.

[0037] In this embodiment, as Figure 2 and Figure 3 As shown, the pull mechanism 3 includes a fixed socket 31 and a movable socket 32 ​​for respectively connecting the two ends of the coil 2. The fixed socket 31 is fixed on the base 1, and the movable socket 32 ​​is slidably mounted on the base 1. The base 1 is provided with a driving component 33 for sliding the movable socket 32 ​​relative to the fixed socket 31. In use, the two ends of the coil 2 are fitted onto the fixed socket 31 and the movable socket 32. Driven by the driving component 33, the coil 2 is in a standard ring shape and suspended in the air.

[0038] In this embodiment, as Figure 2 and Figure 3As shown, the driving assembly 33 includes a first support 331, a second support 332, a pull rod 333, a connecting rod 334, and a handle 335. The first support 331 and the second support 332 are fixedly spaced on the base 1. The handle 335 is slidably mounted on the first support 331, with one end of the handle 335 hinged to the second support 332. One end of the connecting rod 334 is hinged to the middle of the handle 335, and the other end is hinged to one end of the pull rod 333. The other end of the pull rod 333 is connected to the movable socket 32. The handle 335, the connecting rod 334, and the pull rod 333 are connected to form a crank-slider mechanism, where the handle 335 is equivalent to a crank, and the pull rod 333 is equivalent to a slider. Under the rotational action of the handle 335, the pull rod 333 can be driven to slide, thereby driving the movable socket 32 ​​to slide. In practical use, the two ends of coil 2 are fitted onto the fixed socket 31 and the movable socket 32, and then the handle 335 is rotated to slide the movable socket 32 ​​away from the fixed socket 31, thereby pulling coil 2 into the specified ring shape. The structure is ingeniously designed and easy to operate.

[0039] In this embodiment, as Figure 2 As shown, a guide sleeve 336 is provided on the first support 331, and the pull rod 333 is slidably sleeved in the guide sleeve 336. Under the guiding action of the guide sleeve 336, the pull rod 333 slides stably.

[0040] In this embodiment, as Figure 2 , Figure 3 and Figure 8 As shown, the movable socket 32 ​​includes a slider 321 and a movable sleeve shaft 322. The slider 321 is slidably mounted on the base 1, and the movable sleeve shaft 322 is fixed to one side of the slider 321. The coil 2 is sleeved on the movable sleeve shaft 322, making operation convenient.

[0041] In this embodiment, as Figure 7 and Figure 8 As shown, a guide rail 11 is provided on the base 1, and a slider 321 is slidably mounted on the guide rail 11. Specifically, the guide rail 11 is provided with a T-shaped groove, and the bottom of the slider 321 is provided with a T-shaped part that matches the T-shaped groove. The T-shaped part at the bottom of the slider 321 is slidably mounted in the T-shaped groove of the guide rail 11 to prevent left and right jumping and to ensure stable sliding.

[0042] In this embodiment, as Figure 2 , Figure 3 and Figure 6As shown, the fixed sleeve base 31 includes a fixed block 311 and a fixed sleeve shaft 312. The fixed block 311 is fixed on the base 1, and the fixed sleeve shaft 312 is fixed on one side of the fixed block 311 and is positioned opposite to the movable sleeve shaft 322. Before docking, the two ends of the coil 2 are respectively sleeved on the movable sleeve shaft 322 and the fixed sleeve shaft 312. Under the shaping and pulling action of the movable sleeve shaft 322 and the fixed sleeve shaft 312, the coil 2 is pulled into a standard ring shape, which facilitates subsequent bending operations. Specifically, the fixed sleeve shaft 312 is threadedly connected to the fixed block 311 to facilitate adjustment of the overhang length and is locked by a lock nut; the movable sleeve shaft 322 is threadedly connected to the slider 321 to facilitate adjustment of the overhang length.

[0043] In this embodiment, the pull rod 333 is threadedly connected to the movable socket 32. This facilitates adjustment of the initial distance between the movable socket 32 ​​and the fixed socket 31, meeting the docking requirements of coils 2 of different lengths. Furthermore, it allows the movable socket 32 ​​and the fixed socket 31 to be at a specific initial distance. In this position, when the rotating handle 335 is rotated to a horizontal state to tighten the coil 2, the rotating handle 335 is in a self-locking state. Specifically, the pull rod 333 is threadedly connected to the slider 321 of the movable socket 32.

[0044] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, the bending mechanism 4 includes a slide 41 and a wrench 42. The slide 41 is slidably mounted on the base 1. The wrench 42 includes a bending operation block 421 and a rotating handle 422 fixed on the bending operation block 421. The bending operation block 421 is provided with a bending post 423 and two limiting strips 424. The two limiting strips 424 are located on both sides of the bending post 423. A passage interval 425 is formed between the limiting strips 424 and the bending post 423 for the coil lead 21 to pass through. The top surface of the slide 41 is provided with a stop pin 411 and a cylindrical template 412. The center of the cylindrical template 412 is provided with a circular hole 413 for the bending post 423 to be inserted. During bending, firstly, the coil lead 21 is placed between the stop pin 411 and the cylindrical template 412 on the slide 41. Then, the wrench 42 is fitted onto the slide 41, causing the bending pin 423 to be inserted into the circular hole 413 of the cylindrical template 412. At this time, the coil lead 21 is located between the cylindrical template 412 and the limiting strip 424. Finally, by rotating the lever 422, the bending operation block 421 is rotated. Under the squeezing action of the limiting strip 424 and the guiding action of the cylindrical template 412, the coil lead 21 is bent into shape in the desired direction. The structure is simple and the operation is convenient.

[0045] In this embodiment, a pad 12 is provided on the base 1, and the slide 41 slides on the pad 12. By using pads 12 of different heights, it is possible to accommodate bending operations of coil leads 21 of different heights. Specifically, a limiting block is provided at the end of the pad 12. During the bending operation, a shim (not shown in the figure) can be placed between the slide 41 and the pad 12 to raise the coil lead 21 to the required height before bending.

[0046] The radial dimension of the coil lead 21 bend is controlled by the slide block 41, and the height dimension of each coil lead 21 bend is controlled by placing shims of different thicknesses between the slide block 41 and the pad block 12, so that multiple coil leads 21 can be stacked after bending.

[0047] During bending, the coil lead 21 is supported by the stop pin 411 on the slide 41, and bending is achieved by rotating the wrench 42. At the same time, the top surface of the slide 41 can be marked with angles to meet different bending angle requirements, ensuring the required bending angle of the coil lead 21 and improving bending efficiency and quality.

[0048] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
