Description

Technical Field

[0001] This utility model relates to the technical field of motor base measuring equipment, specifically a measuring tool for machining traction motor bases. Background Technology

[0002] In electric motors, the frame is a crucial hardware component. It primarily serves as the mechanical support for the stator core and windings, and is used to secure end covers or end shields. In some cases, it also forms the airflow path or ventilation chamber of the ventilation system. Existing motor frames have a fully circular structure, offering good rigidity and ease of machining. After the motor frame is machined, its length needs to be measured to determine if its parallelism meets standards.

[0003] The prior art patent application number is 202321650760.8, entitled "A Measuring Tool for Processing Traction Motor Bases," which includes an operating box with a rotating mechanism and a lifting mechanism, and a controller on the top of the operating box. This utility model is reasonably designed. By incorporating a clamping mechanism, it can clamp and fix the motor base using two clamping pads. By incorporating an adjustment mechanism, it can drive a dial indicator and measuring rod to adjust the distance to the motor base, enabling measurement of motor bases of different sizes. By incorporating a rotating mechanism, it can drive the motor base to rotate. The measuring rod and dial indicator can measure the parallelism of the motor base, achieving precise measurement of the motor base and thus improving measurement accuracy.

[0004] However, its design, which uses two flat clamping plates to fix the motor base, revealed problems with poor clamping effect in actual operation: since the outer contour of the motor base is mostly an irregular curved surface or a curved structure, the flat clamping plates have poor contact with the surface of the base, and can only apply clamping force through edge contact. This not only easily causes the base to wobble or shift slightly during processing, but may also cause damage such as indentations and deformation on the surface of the base due to uneven force. In addition, this clamping method has weak adaptability to motor bases of different specifications. When there are slight differences in the size or shape of the base, it is difficult to ensure a stable clamping force, which affects the accuracy of subsequent assembly or processing procedures and increases the quality risk in the production process. Therefore, we propose a measuring tool for processing traction motor bases. Utility Model Content

[0005] The purpose of this utility model is to provide a measuring tool for machining traction motor bases, in order to solve the problem of poor clamping effect in actual operation of the design proposed in the background art, which uses two flat clamps to fix the motor base: since the outer contour of the motor base is mostly an irregular curved surface or a curved structure, the flat clamps have poor fit with the base surface, and can only apply clamping force through edge contact, which can easily cause the base to wobble or shift slightly during machining.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a measuring tool for machining traction motor bases, comprising a motor base measuring tool and a mounting base, wherein the mounting base is fixedly connected to the top of the motor base measuring tool, and a bidirectional screw is rotatably connected to the inner cavity of the mounting base, one end of the bidirectional screw passing through the mounting base and extending to the outside of the mounting base, the other end of the bidirectional screw passing through the mounting base and extending to the outside of the mounting base, and an extension rod fixedly connected to the other end of the bidirectional screw, wherein a snap-fit ​​groove is provided on the outer side of the extension rod.

[0007] As a further description of the above technical solution: The snap-fit ​​slots are arranged in sequence, and two connecting plates are screwed to the outer side of the bidirectional screw.

[0008] As a further description of the above technical solution: A V-shaped clamping plate is fixedly connected to the top of the connecting plate, and an anti-slip pad is glued to one side of the V-shaped clamping plate.

[0009] As a further description of the above technical solution: Two mounting brackets are fixedly connected to one side of the mounting base. A mounting rod is fixedly connected to the inner side of the mounting bracket, and two compression springs are sleeved on the outer side of the mounting rod.

[0010] As a further description of the above technical solution: One end of the compression spring is fixedly connected to the mounting bracket, and a fixing plate is slidably connected to the outside of the mounting rod.

[0011] As a further description of the above technical solution: A locking block is fixedly connected to one side of the fixing plate, and a damping rubber pad is adhered to one side of the locking block.

[0012] As a further description of the above technical solution: The damping rubber pad is in contact with the snap-fit ​​groove, and a separation block is slidably connected to one side of the mounting bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This measuring tool for machining traction motor bases, when the double-ended screw is rotated, the two connecting plates screwed to its outer sides are adapted to the positive and negative threads of the double-ended screw, and the two connecting plates will move relatively closer or further away along the axial direction of the double-ended screw. The V-shaped clamping plate fixed on the top of the connecting plate moves synchronously. When the two V-shaped clamping plates approach each other, the fitting characteristics of the V-shaped structure can be used to form a stable clamping of the motor base, which can be adapted to the outer contour of the base of different sizes. The anti-slip pad glued to one side of the V-shaped clamping plate increases the friction with the surface of the motor base, effectively preventing the base from sliding during the clamping process, enhancing the stability of the clamping, and realizing the reliable fixing or loosening of the motor base.

[0014] 2. This measuring tool for machining traction motor bases, in its natural state, has a compression spring on the outside of the mounting rod in a compressed state, generating a thrust on the fixing plate. This causes the fixing plate to move the locking block towards the extension rod. The damping rubber pad on one side of the locking block is tightly embedded in the snap-fit ​​groove on the outside of the extension rod. The friction between the damping rubber pad and the snap-fit ​​groove restricts the rotation of the extension rod, thereby fixing the position of the bidirectional screw. When unlocking is required, the separating block on one side of the sliding mounting bracket pushes the fixing plate to overcome the elastic force of the compression spring and move along the mounting rod away from the extension rod, causing the damping rubber pad to disengage from the snap-fit ​​groove and releasing the restriction on the extension rod. At this time, the bidirectional screw can rotate freely, completing the switching of the locking state. Attached Figure Description

[0019] This utility model provides a measuring tool for machining traction motor bases, which can be adapted to the outer contours of bases of different sizes, effectively preventing the base from sliding during clamping and enhancing the stability of clamping. Please refer to [link to relevant documentation]. Figure 1-5 This includes a motor base measuring tool 100 and a mounting base 200; Please refer to it again. Figure 1-4The mounting base 200 is fixedly connected to the top of the motor base measuring tool 100. A bidirectional screw 210 is rotatably connected to the inner cavity of the mounting base 200. One end of the bidirectional screw 210 passes through the mounting base 200 and extends to the outside of the mounting base 200. The other end of the bidirectional screw 210 passes through the mounting base 200 and extends to the outside of the mounting base 200. An extension rod 220 is fixedly connected to the other end of the bidirectional screw 210. A snap-fit ​​groove 230 is provided on the outer side of the extension rod 220, and the snap-fit ​​grooves 230 are arranged sequentially. Two connecting plates 300 are screwed to the outer side of the bidirectional screw 210. A V-shaped clamping plate 310 is fixedly connected to the top of the connecting plate 300. A V-shaped clamping plate 310 has an anti-slip pad 320 bonded to one side. When the bidirectional screw 210 is rotated, the two connecting plates 300 screwed to its outer side are adapted to the positive and negative threads of the bidirectional screw 210, and the two connecting plates 300 will move relatively closer or further away along the axial direction of the bidirectional screw 210. The V-shaped clamping plate 310 fixed at the top of the connecting plate 300 moves synchronously. When the two V-shaped clamping plates 310 approach each other, the fitting characteristics of the V-shaped structure can be used to form a stable clamping of the motor base, which can be adapted to the outer contour of the base of different sizes. The anti-slip pad 320 bonded to one side of the V-shaped clamping plate 310 increases the friction with the surface of the motor base. In summary, this effectively prevents the base from sliding during clamping, enhances the stability of clamping, and enables reliable fixing or loosening of the motor base. Please refer to it again. Figure 1-5 Two mounting brackets 400 are fixedly connected to one side of the mounting base 200. A mounting rod 410 is fixedly connected to the inner side of each mounting bracket 400. Two compression springs 420 are sleeved on the outer side of each mounting rod 410. One end of each compression spring 420 is fixedly connected to the mounting bracket 400. A fixing plate 430 is slidably connected to the outer side of the mounting rod 410. A locking block 500 is fixedly connected to one side of the fixing plate 430. A damping rubber pad 510 is adhered to one side of the locking block 500 and contacts the locking groove 230. A separating block 600 is slidably connected to one side of the mounting bracket 400. In its natural state, the compression springs 420 on the outer side of the mounting rod 410 are compressed, generating a pushing force on the fixing plate 430, thus fixing... The plate 430 drives the locking block 500 to move towards the extension rod 220. The damping rubber pad 510 on one side of the locking block 500 is tightly embedded in the snap-fit ​​groove 230 on the outside of the extension rod 220. The friction between the damping rubber pad 510 and the snap-fit ​​groove 230 restricts the rotation of the extension rod 220, thereby fixing the position of the bidirectional screw 210. When unlocking is required, the separating block 600 on one side of the sliding mounting bracket 400 pushes the fixing plate 430 to overcome the elastic force of the compression spring 420 and move along the mounting rod 410 away from the extension rod 220, so that the damping rubber pad 510 disengages from the snap-fit ​​groove 230, releasing the restriction on the extension rod 220. At this time, the bidirectional screw 210 can rotate freely, completing the switching of the locking state. In summary, the bidirectional screw 210 can be locked to prevent it from rotating. In practical use, when those skilled in the art rotate the bidirectional screw 210, the two connecting plates 300 screwed to its outer side are adapted to the positive and negative threads of the bidirectional screw 210, and the two connecting plates 300 will move relatively closer or further away along the axial direction of the bidirectional screw 210. The V-shaped clamping plate 310 fixed on the top of the connecting plate 300 moves synchronously. When the two V-shaped clamping plates 310 approach each other, the fitting characteristics of the V-shaped structure can be used to form a stable clamping of the motor base, adapting to the outer contour of the base of different sizes. The anti-slip pad 320 adhered to one side of the V-shaped clamping plate 310 increases the friction with the surface of the motor base, effectively preventing the base from sliding during clamping, enhancing the stability of the clamping, and realizing reliable fixing or loosening of the motor base. In the natural state, the outer side of the mounting rod 410 is pressed. When the spring 420 is compressed, it exerts a thrust on the fixed plate 430, causing the fixed plate 430 to move the locking block 500 toward the extension rod 220. The damping rubber pad 510 on one side of the locking block 500 is tightly embedded in the snap-fit ​​groove 230 on the outside of the extension rod 220. The friction between the damping rubber pad 510 and the snap-fit ​​groove 230 restricts the rotation of the extension rod 220, thereby fixing the position of the bidirectional screw 210. When unlocking is required, the separating block 600 on one side of the sliding mounting bracket 400 pushes the fixed plate 430 to overcome the elastic force of the compression spring 420 and move along the mounting rod 410 away from the extension rod 220, causing the damping rubber pad 510 to disengage from the snap-fit ​​groove 230 and releasing the restriction on the extension rod 220. At this time, the bidirectional screw 210 can rotate freely, completing the switching of the locking state.
