Description

Technical Field

[0001] This utility model relates to the technical field of rotor assembly fixtures for micro motor production, specifically a rotor assembly fixture for micro motor production. Background Technology

[0002] Motor rotor: This is the rotating component of an electric motor. An electric motor consists of two parts: the rotor and the stator. It is a device used to convert electrical energy into mechanical energy and vice versa. Motor rotors are divided into electric motor rotors and generator rotors.

[0003] In the production of micro motors, rotor assembly is a crucial step. Existing rotor assembly fixtures have several problems in use. For example, insufficient clamping stability can easily cause the rotor to shift or wobble during assembly, affecting assembly accuracy; some fixtures cannot effectively fix rotors of different sizes, resulting in poor applicability. Therefore, a rotor assembly fixture for micro motor production is proposed to solve the above-mentioned problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a rotor assembly fixture for micro motor production, which has the advantages of stable clamping and strong applicability, and solves the problems of unstable clamping and poor applicability of existing fixtures.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A rotor assembly fixture for micro motor production includes a housing, a fixed plate fixedly connected to the top of the housing, a transmission mechanism rotatably connected to the left side of the fixed plate inside the housing, two auxiliary mechanisms symmetrically distributed on the left and right sides fixedly connected to the top of the housing, the auxiliary mechanisms being located on the right side of the fixed plate, and a clamping mechanism located on the right side of the auxiliary mechanisms and coaxially arranged with the fixed plate inside the housing.

[0008] The clamping mechanism includes a slide rod, which is fixedly connected to the inside of the equipment housing. An anti-deviation sleeve is slidably connected to the outside of the slide rod. The anti-deviation sleeve and the inside of the equipment housing are both fixedly connected to mounting rings arranged symmetrically on the left and right. The outside of the two mounting rings are fixedly connected to the same tension spring located outside the slide rod. The top of the anti-deviation sleeve is fixedly connected to a fixing rod extending to the top of the equipment housing. The top of the fixing rod is fixedly connected to a clamping block.

[0009] The beneficial effects of this utility model are:

[0010] The clamping mechanism can stably hold the rotor and prevent it from shifting during assembly and winding; the auxiliary mechanism can help support the rotor and further improve stability; the transmission mechanism ensures stable and efficient rotor transmission, and the overall structure can adapt to rotors of different sizes.

[0011] This rotor assembly fixture for micro-motor production has the advantages of stable clamping and strong applicability.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the device housing has a transmission cavity adapted to the transmission device inside, and a sliding cavity located on the right side of the transmission cavity and adapted to the clamping mechanism inside the device housing. The top of the sliding cavity has a sliding groove adapted to the fixed rod.

[0014] The beneficial effects of adopting the above-mentioned further solutions are that the transmission cavity provides installation space for the transmission equipment and ensures stable operation of the transmission mechanism; the sliding cavity and the slide groove provide guidance for the movement of the clamping mechanism, enabling the clamping block to smoothly clamp and release the rotor, thereby improving the accuracy and stability of clamping.

[0015] Furthermore, the fixed insert plate and the clamping block are internally connected to the same rotor that contacts the top of the auxiliary mechanism, and the fixed insert plate and the clamping block are rotatably connected to rotating rings that contact the left and right sides of the rotor on opposite sides.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the rotating ring can reduce the friction between the rotor and the fixed insert plate and clamping block during the rotation process, making the rotor rotate more smoothly and ensuring the transmission accuracy of the rotor during the assembly process.

[0017] Furthermore, the fixed insert plate and the clamping block each have an insertion hole on their opposite sides that is adapted to the rotor shaft. Both insertion holes on both sides are tapered, and the side with the larger opening of the insertion hole on both sides faces the rotor.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the tapered insertion hole facilitates the insertion of the rotor shaft, and at the same time, it can play a certain role in positioning and clamping the shaft after insertion, thereby improving the stability and accuracy of rotor installation.

[0019] Furthermore, the transmission mechanism includes an electric motor, which is fixedly connected inside the equipment housing. A first pulley is fixedly connected to the output end of the electric motor. A second pulley is rotatably connected to the left side of the fixed insert plate. The outer sides of the second pulley and the first pulley are connected by the same belt. The second pulley is located outside the rotor shaft. An extrusion tube is fixedly connected inside the second pulley. The inner side of the extrusion tube contacts the outer side of the rotor shaft. The extrusion tube is made of rubber.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the electric motor transmits power to the rotor stably through the first pulley, belt and second pulley. The rubber extrusion tube can not only make close contact with the rotor shaft to ensure power transmission, but also avoid damage to the shaft, thus ensuring stable and efficient rotor transmission.

[0021] Furthermore, the auxiliary mechanism includes a telescopic rod, which is fixedly connected to the top of the equipment housing. A wheel frame is fixedly connected to the top of the telescopic rod. The wheel frame is U-shaped, and two support wheels are rotatably connected inside the wheel frame and are symmetrically distributed front and back. Both support wheels are in contact with the outer side of the rotor. The bottom of the wheel frame is fixedly connected to the top of the equipment housing, and a spring located outside the telescopic rod is fixedly connected to it.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the cooperation of the telescopic rod and the spring allows the support wheel to automatically adjust its height and pressure according to the size of the rotor, which can play a good supporting role for rotors of different sizes, ensuring the stability of the rotor during the assembly process. At the same time, the buffering effect of the spring can avoid rigid damage to the rotor. Attached Figure Description

[0028] 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.

[0029] In the embodiments, by Figure 1-4 The present invention provides a rotor assembly fixture for micro motor production. The fixture includes a housing 1, a fixed plate 2 fixedly connected to the top of the housing 1, a transmission mechanism 3 rotatably connected to the left side of the fixed plate 2 inside the housing 1, two auxiliary mechanisms 4 symmetrically distributed on the left and right sides fixedly connected to the top of the housing 1, the auxiliary mechanisms 4 being located on the right side of the fixed plate 2, and a clamping mechanism 5 located on the right side of the auxiliary mechanisms 4 and coaxially arranged with the fixed plate 2 inside the housing 1.

[0030] The clamping mechanism 5 includes a slide rod 501, which is fixedly connected to the inside of the equipment housing 1. An anti-deviation sleeve 502 is slidably connected to the outside of the slide rod 501. The anti-deviation sleeve 502 and the inside of the equipment housing 1 are both fixedly connected to mounting rings 503 arranged symmetrically on the left and right. The outside of the two mounting rings 503 are fixedly connected to the same tension spring 504 located outside the slide rod 501. The top of the anti-deviation sleeve 502 is fixedly connected to a fixing rod 505 extending to the top of the equipment housing 1. The top of the fixing rod 505 is fixedly connected to a clamping block 506.

[0031] The equipment housing 1 has a transmission cavity 6 adapted to the transmission equipment inside. The equipment housing 1 also has a sliding cavity 7 located on the right side of the transmission cavity 6 and adapted to the clamping mechanism 5 inside. The top of the sliding cavity 7 has a sliding groove 8 adapted to the fixed rod 505.

[0032] The transmission cavity 6 provides installation space for the transmission equipment and ensures the stable operation of the transmission mechanism 3; the sliding cavity 7 and the slide groove 8 provide guidance for the movement of the clamping mechanism 5, so that the clamping block 506 can smoothly clamp and release the rotor 9, improving the accuracy and stability of clamping.

[0033] The fixed insert plate 2 and the clamping block 506 are connected to the same rotor 9 that is in contact with the top of the auxiliary mechanism 4. The fixed insert plate 2 and the clamping block 506 are rotatably connected to rotating rings 10 that are in contact with the left and right sides of the rotor 9.

[0034] The rotating ring 10 can reduce the friction between the rotor 9 and the fixed insert plate 2 and the clamping block 506 during rotation, making the rotor 9 rotate more smoothly and ensuring the transmission accuracy of the rotor 9 during assembly.

[0035] The fixed insert plate 2 and the clamping block 506 are respectively provided with an insertion hole 11 that is adapted to the rotor shaft 9. The insertion holes 11 on both sides are tapered, and the side with the larger opening of the insertion hole 11 on both sides faces the rotor 9.

[0036] The tapered insertion hole 11 facilitates the insertion of the rotor 9 shaft, and at the same time, it can provide a certain positioning and clamping effect on the shaft after insertion, thereby improving the stability and accuracy of rotor 9 installation.

[0037] The transmission mechanism 3 includes an electric motor 301, which is fixedly connected inside the equipment housing 1. The output end of the electric motor 301 is fixedly connected to a first pulley 302. A second pulley 303 is rotatably connected to the left side of the fixed insert plate 2. The second pulley 303 and the first pulley 302 are connected by the same belt 304. The second pulley 303 is located outside the rotor shaft of the rotor 9. An extrusion tube 305 is fixedly connected inside the second pulley 303. The inner side of the extrusion tube 305 contacts the outer side of the rotor shaft of the rotor 9. The extrusion tube 305 is made of rubber.

[0038] The electric motor 301 transmits power stably to the rotor 9 through the first pulley 302, the belt 304, and the second pulley 303. The rubber extrusion tube 305 can not only make close contact with the rotor shaft of the rotor 9 to ensure power transmission, but also avoid damage to the shaft, thus ensuring stable and efficient transmission of the rotor 9.

[0039] The auxiliary mechanism 4 includes a telescopic rod 401, which is fixedly connected to the top of the equipment housing 1. A wheel frame 402 is fixedly connected to the top of the telescopic rod 401. The wheel frame 402 is U-shaped. Two support wheels 403 are rotatably connected inside the wheel frame 402 and are symmetrically distributed front and back. Both support wheels 403 are in contact with the outer side of the rotor 9. The bottom of the wheel frame 402 and the top of the equipment housing 1 are fixedly connected to the same spring 404 located outside the telescopic rod 401.

[0040] The cooperation between the telescopic rod 401 and the spring 404 allows the support wheel 403 to automatically adjust its height and pressure according to the size of the rotor 9, providing good support for rotors 9 of different sizes and ensuring the stability of the rotor 9 during assembly. At the same time, the buffering effect of the spring 404 can prevent rigid damage to the rotor 9.

[0041] Working principle:

[0042] Step 1: Insert one end of the rotor 9 to be assembled into the insertion hole 11 of the fixing plate 2. Since the insertion hole 11 is conical, it is convenient for the rotor 9 shaft to be quickly positioned and inserted. Then, manually push the clamping block 506 to make the anti-deviation sleeve 502 slide on the slide rod 501 and the tension spring 504 is stretched. Insert the other end of the rotor 9 into the insertion hole 11 of the clamping block 506. Release the clamping block 506. Under the action of the tension spring 504, the clamping block 506 clamps and fixes the rotor 9.

[0043] Step 2: During the process of clamping and fixing the rotor 9, the support wheel 403 of the auxiliary mechanism 4 contacts the outside of the rotor 9, and the telescopic rod 401 and spring 404 automatically adjust according to the size of the rotor 9 to provide auxiliary support for the rotor 9 and ensure the stability of the rotor 9 in the horizontal direction.

[0044] Step 3: Start the electric motor 301. The electric motor 301 drives the first pulley 302 to rotate slowly, transmitting power to the second pulley 303 via the belt 304. The extrusion tube 305 inside the second pulley 303 contacts the rotor 9 shaft, causing the rotor 9 to rotate slowly for winding assembly. During the rotation of the rotor 9, the rotating ring 10 reduces friction between the rotor 9 and the fixed insert plate 2 and the clamping block 506, ensuring smooth rotation. When it is necessary to replace the rotor 9 with a different size, the above operation can be repeated.
