Description
Technical Field
[0001] This utility model relates to the field of motor assembly, specifically an armature transfer inner support clamp. Background Technology
[0002] Motor assembly is a crucial step in the motor manufacturing process, involving the assembly and debugging of multiple components. After assembly, a comprehensive inspection and testing should be conducted to ensure that the motor's performance and safety meet the requirements.
[0003] During the motor manufacturing process, the armature needs to be moved. For example, during motor assembly, the armature needs to be accurately installed into the stator cavity; during motor repair, the armature may need to be removed from the motor for inspection or replacement; during motor testing, the armature may also need to be moved to the testing equipment for testing.
[0004] Existing armature-type workpieces are usually clamped on their outer wall during transfer. However, during production and observation, it has been found that this clamping method can easily damage the workpiece surface, thereby affecting the processing quality of the workpiece.
[0005] Therefore, an armature transfer internal support clamp is proposed to address the above problems. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: An armature transfer internal support clamp of this utility model includes a mounting base, on one side of which a power component is mounted; a first gear is rotatably connected to the other side of the mounting base; the output end of the power component and the first gear are fixedly connected; multiple second gears are rotatably connected to the middle of the mounting base; the first gear and the second gear are meshed; a connecting rod is fixedly connected to the middle of the second gear; a first top plate is fixedly connected to the middle of the connecting rod; the surface of the first top plate has an arc-shaped structure; through the meshing action of the first gear and the second gear, the first top plate rotates with the connecting rod and squeezes the inner wall of the workpiece, thereby achieving rapid fixation of armature-type workpieces and reducing damage to the workpiece caused by clamping its outer diameter.
[0008] Preferably, a plurality of spring telescopic rods are fixedly connected to the inner sidewall of the first top plate; a second top plate is fixedly connected to the end of each spring telescopic rod; the surface of the second top plate is an arc-shaped structure; through the cooperation of the second top plate and the spring telescopic rods, the second top plate will press against the inner wall of the workpiece under the elastic force of the spring telescopic rods, increasing the contact area between the first top plate and the inner wall of the workpiece, and improving the stability of the fixture in fixing the workpiece.
[0009] Preferably, the inner wall of the second top plate is symmetrically fixed with pull ropes; the pull ropes and the first top plate are through-connected; the two sides of the first top plate are rotatably connected with connecting plates; the connecting plates and the first top plate are connected by torsion springs; the pull ropes and connecting plates are fixedly connected; a push rod is fixedly connected to the end of the connecting plate; the connecting plate is in a stable state under the tension of the pull ropes and is located on one side of the first top plate, and the torsion spring is also in a bent state. When the second top plate contacts the workpiece, it enters the interior of the first top plate. At this time, the pull ropes will slacken and the connecting plate will move closer to the inner wall of the workpiece under the elastic force of the torsion spring. The push rod will move together with the connecting plate until the push rod contacts the inner wall of the workpiece, so that the push rod will also squeeze the inner wall of the workpiece, further increasing the contact area between the device and the workpiece and improving the stability of the device in fixing the workpiece.
[0010] Preferably, protective pads are symmetrically fixed at both ends of the push rod; the protective pads are flexible; when the push rod contacts the inner wall of the workpiece, the protective pads will also contact the workpiece. Because the surface of the protective pads is made of flexible material, the pressure exerted on the workpiece by the push rod will be dispersed, reducing damage to the inner wall of the workpiece caused by excessive compression.
[0011] Preferably, a support frame is fixedly connected to the middle of the connecting rod; the support frame is arched; multiple ball bearings are rotatably connected to the middle of the support frame; before fixing the workpiece, the workpiece needs to be sleeved on the surface of the connecting rod. When the workpiece moves, it will move along the surface of the support frame until the workpiece is in the arched part of the support frame, which facilitates the device to position the workpiece. When the workpiece and the support frame come into contact, they will rub against the ball bearings and cause the ball bearings to rotate. The ball bearings will reduce the wear caused by friction between the workpiece and the support frame.
[0012] Preferably, a plurality of brush bristles are symmetrically fixed to the middle of the support frame; the brush bristles are arranged in an array; when the workpiece moves along the support frame, it will come into contact with the brush bristles, and the brush bristles will clean the inner wall of the workpiece, reducing the impurities adhering to the inner wall of the workpiece.
[0013] The advantages of this utility model are:
[0014] 1. The armature transfer inner support clamp of this utility model, through the meshing action of the first gear and the second gear, causes the first top plate to rotate with the connecting rod and squeeze the inner wall of the workpiece, thereby realizing the device to quickly fix the armature workpiece and reduce the damage to the workpiece caused by clamping the outer diameter.
[0015] 2. The armature transfer internal support fixture of this utility model, through the cooperation of the second top plate and the spring telescopic rod, causes the second top plate to squeeze the inner wall of the workpiece under the elastic force of the spring telescopic rod, thereby increasing the contact area between the first top plate and the inner wall of the workpiece and improving the stability of the fixture in fixing the workpiece.

[0023] 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 scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] Please see Figures 1 to 5As shown in the embodiment of this utility model, an armature transfer internal support clamp includes a mounting base 1. A power assembly 12 is mounted on one side of the mounting base 1. A first gear 13 is rotatably connected to the other side of the mounting base 1. The output end of the power assembly 12 and the first gear 13 are fixedly connected. A plurality of second gears 14 are rotatably connected to the middle of the mounting base 1. The first gear 13 and the second gears 14 are meshed. A connecting rod 15 is fixedly connected to the middle of the second gear 14. A first top plate 16 is fixedly connected to the middle of the connecting rod 15. The surface of the first top plate 16 has an arc-shaped structure. During operation, the mounting base 1 can be installed on a transfer robot as needed. When it is necessary to fix the workpiece, the workpiece is placed on the surface of the connecting rod 15, and then the operator can start the power assembly 12. The first gear 13 rotates, meshing with the other second gears 14, causing the connecting rod 15 to rotate. Before fixing the workpiece, the first top plate 16 is located inside the connecting rod 15. When the second gears 14 mesh, the first top plate 16 rotates with the connecting rod 15. As the first top plate 16 rotates, its end gradually contacts the inner wall of the workpiece. When the first top plate 16 rotates to its farthest distance, all the first top plates 16 support the inner wall of the workpiece, enabling the device to quickly fix the workpiece. Through the meshing action of the first gear 13 and the second gear 14, the first top plate 16 rotates with the connecting rod 15 and squeezes the inner wall of the workpiece, enabling the device to quickly fix armature-type workpieces and reduce damage to the workpiece caused by clamping the outer diameter.
[0026] Please see Figure 3 and Figure 4 As shown, a plurality of spring telescopic rods 22 are fixedly connected to the inner wall of the first top plate 16; a second top plate 2 is fixedly connected to the end of each spring telescopic rod 22; the surface of the second top plate 2 is an arc-shaped structure; when the first top plate 16 contacts the inner wall of the workpiece, the second top plate 2 will move together with the first top plate 16. Because there is a processing error in the inner wall of the workpiece, the second top plate 2 will enter the interior of the first top plate 16 under the squeezing action when it contacts the inner wall of the workpiece, and the spring telescopic rods 22 will also be in a compressed state. Subsequently, the second top plate 2 will squeeze the inner wall of the workpiece under the elastic force of the spring telescopic rods 22, increasing the contact area between the first top plate 16 and the inner wall of the workpiece; through the cooperation of the second top plate 2 and the spring telescopic rods 22, the second top plate 2 will squeeze the inner wall of the workpiece under the elastic force of the spring telescopic rods 22, increasing the contact area between the first top plate 16 and the inner wall of the workpiece, and improving the stability of the fixture in fixing the workpiece.
[0027] Please see Figure 4As shown, pull ropes 3 are symmetrically fixed to the inner wall of the second top plate 2; the pull ropes 3 and the first top plate 16 are through-connected; connecting plates 32 are rotatably connected to both sides of the first top plate 16; the connecting plates 32 and the first top plate 16 are connected by torsion springs; the pull ropes 3 and the connecting plates 32 are fixedly connected; a top rod 33 is fixedly connected to the end of the connecting plate 32; the connecting plate 32 will be in a stable state under the tension of the pull ropes 3 and located on one side of the first top plate 16, and the torsion spring will also be in a bent state. When the second top plate 2 contacts the workpiece, it will enter the interior of the first top plate 16. At this time, the pull ropes 3 will slacken and the connecting plate 32 will move closer to the inner wall of the workpiece under the elastic force of the torsion spring. The top rod 33 will move together with the connecting plate 32 until the top rod 33 contacts the inner wall of the workpiece, so that the top rod 33 will also squeeze the inner wall of the workpiece, further increasing the contact area between the device and the workpiece and improving the stability of the device in fixing the workpiece.
[0028] Please see Figure 4 As shown, protective pads 4 are symmetrically fixed at both ends of the push rod 33; the protective pads 4 are flexibly designed; when the push rod 33 contacts the inner wall of the workpiece, the protective pads 4 will also contact the workpiece. Because the surface of the protective pads 4 is made of flexible material, the pressure exerted on the workpiece by the push rod 33 will be dispersed, reducing the damage to the inner wall of the workpiece caused by excessive compression.
[0029] Please see Figure 2 and Figure 5 As shown, a support frame 5 is fixedly connected to the middle of the connecting rod 15; the support frame 5 is arched; a plurality of ball bearings 52 are rotatably connected to the middle of the support frame 5; before fixing the workpiece, the workpiece needs to be sleeved on the surface of the connecting rod 15. When the workpiece moves, it will move along the surface of the support frame 5 until the workpiece is in the arched part of the support frame 5, which facilitates the device to position the workpiece. When the workpiece and the support frame 5 come into contact, they will rub against the ball bearings 52 and cause the ball bearings 52 to rotate. The ball bearings 52 will reduce the wear caused by friction between the workpiece and the support frame 5.
[0030] Please see Figure 5 As shown, multiple brush bristles 6 are symmetrically fixed to the middle of the support frame 5; the brush bristles 6 are arranged in an array; when the workpiece moves along the support frame 5, it will come into contact with the brush bristles 6, and the brush bristles 6 will clean the inner wall of the workpiece, reducing the impurities attached to the inner wall of the workpiece.
[0031] Please see Figure 5 As shown, the surface of the support frame 5 has an arc transition; because the surface of the support frame 5 has an arc transition, the resistance encountered by the workpiece when moving along the surface of the support frame 5 is smaller, further reducing the damage caused by squeezing when the workpiece moves.
[0032] Working principle: The mounting base 1 is installed on the transfer robot according to requirements. When a workpiece needs to be fixed, it is placed on the surface of the connecting rod 15. Then, the operator can activate the power assembly 12 to rotate the first gear 13. When the first gear 13 rotates, it meshes with the remaining second gear 14, causing the second gear 14 to drive the connecting rod 15 to rotate. Before fixing the workpiece, the first top plate 16 is located inside the connecting rod 15. When the second gear 14 meshes, it causes the first top plate 16 to rotate with the connecting rod 15. As the first top plate 16 rotates, its end gradually... As the first top plate 16 gradually contacts the inner wall of the workpiece, when it rotates to its furthest point, all the first top plates 16 will support the inner wall of the workpiece, enabling the device to quickly fix the workpiece. When the first top plate 16 contacts the inner wall of the workpiece, the second top plate 2 will move together with the first top plate 16. Due to the machining error of the inner wall of the workpiece, the second top plate 2 will enter the interior of the first top plate 16 under the squeezing action when it contacts the inner wall of the workpiece. The spring telescopic rod 22 will also be in a compressed state. Subsequently, the second top plate 2 will squeeze the inner wall of the workpiece under the elastic force of the spring telescopic rod 22, increasing the first The contact area between the top plate 16 and the inner wall of the workpiece; the connecting plate 32 will be in a stable state under the tension of the pull rope 3 and located on one side of the first top plate 16, and the torsion spring will also be in a bent state. When the second top plate 2 contacts the workpiece, it will enter the interior of the first top plate 16. At this time, the pull rope 3 will slacken and the connecting plate 32 will move closer to the inner wall of the workpiece under the elastic force of the torsion spring. The push rod 33 will move together with the connecting plate 32 until the push rod 33 contacts the inner wall of the workpiece, so that the push rod 33 will also squeeze the inner wall of the workpiece, further increasing the contact area between the device and the workpiece; the push rod 33 and the workpiece When the inner wall of the workpiece comes into contact with the workpiece, the protective pad 4 will also come into contact with the workpiece. Because the surface of the protective pad 4 is made of flexible material, the pressure exerted on the workpiece by the push rod 33 will be dispersed. Before fixing the workpiece, the workpiece needs to be placed on the surface of the connecting rod 15. When the workpiece moves, it will move along the surface of the support frame 5 until the workpiece is in the arched part of the support frame 5, which facilitates the device to position the workpiece. When the workpiece comes into contact with the support frame 5, it will rub against the ball 52 and cause the ball 52 to rotate. When the workpiece moves along the support frame 5, it will come into contact with the brush bristles 6, and the brush bristles 6 will clean the inner wall of the workpiece.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
