Description

Clamping fixture for stator machining Technical Field

[0001] This utility model relates to the field of clamping equipment technology, specifically to a clamping fixture for stator machining. Background Technology

[0002] In the manufacturing process of electric motors, the stator is a crucial component of generators, starters, and other motors. The stator consists of three parts: the stator core, the stator windings, and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force within this rotating magnetic field, thereby generating an electric current.

[0003] In the machining process of motor stators, it is often necessary to fix and clamp them. There are many devices on the market that can clamp motor stators, such as the patent publication number CN211744279U; the patent title is "A Fixing Device for Servo Motor Stator Machining". This patent discloses a fixing device for servo motor stator machining, including a support column, a machining table fixedly connected to the top of the support column, a flange fixedly connected to the bottom of the machining table, a motor fixedly connected to the bottom of the flange, bolts inserted into the bottom of the flange, and a machining turntable fixedly connected to the output end of the motor. The advantages of this invention are: through the coordinated arrangement of the machining turntable, round hole, steel column, stator, preset groove, cylinder body, piston, clamping plate, and groove, the stator can be fixed in two ways, solving the problem of poor clamping and fixing effect affecting stator machining accuracy in existing systems; through the coordinated arrangement of the machining turntable, round hole, steel column, stator, preset groove, cylinder body, air pipe, piston, and clamping plate, the adaptability of the fixing device is improved, solving the problem that existing fixing devices cannot adapt to stators of various sizes.

[0004] However, in the aforementioned patent, the steel column needs to be inserted into the round hole for positioning. However, the position of the round hole is limited. Therefore, in the actual processing, only the stator corresponding to the round hole position can be processed and positioned. It cannot be matched with the clamping and fixing of stators of various diameters. There are many inconveniences in use, and the applicability of the device is poor. Summary of the Invention

[0005] In view of this, the present invention provides a clamping fixture for stator machining, which can adjust the distance between the two clamping plates through an adjustment mechanism to achieve a firm and efficient clamping and fixing operation for workpieces of various specifications, making it more applicable and easier to operate.

[0006] To solve the above-mentioned technical problems, this utility model provides a clamping fixture for stator machining, including a base plate, an adjustment mechanism on the base plate, and a clamping assembly on the adjustment mechanism. The clamping assembly includes a pair of clamping plates disposed on the adjustment mechanism. The adjustment mechanism can adjust the two clamping plates to move in opposite directions. The clamping plates are provided with clamping parts adapted to the outer side wall of the workpiece to be clamped. This utility model can conveniently and efficiently adjust the two clamping plates in opposite directions through the adjustment mechanism, realizing the clamping and fixing of stators of various diameters, greatly improving the fixing efficiency in stator machining and enhancing the machining quality.

[0007] The adjustment mechanism includes a bidirectional telescopic push rod mounted on the base plate. The bidirectional telescopic push rod is either a bidirectional electric push rod or a bidirectional hydraulic push rod. Each bidirectional telescopic push rod has a fixed plate at the end of its output rod, and each fixed plate has a clamping plate on its inner side. This invention can simultaneously move the fixed plate and the clamping plate away from or towards each other by extending and retracting the output rod of the bidirectional telescopic push rod. This not only enables convenient and quick loading and unloading of workpieces to be clamped, but also enables clamping and fixing of workpieces of various sizes.

[0008] Each fixed plate has a guide hole, and a push rod is inserted into each guide hole. One end of the push rod is fixed to the back of the clamping plate located on the same side. The upper part of the fixed plate has a threaded hole that communicates with the guide cylinder. A clamping bolt is threaded into the threaded hole. This utility model can adjust the position of the pressure plate by loosening the clamping bolt and adjusting the distance of the push rod into the guide hole, which greatly increases the clamping adjustment range of the pressure plate and makes it more applicable.

[0009] Each push rod is equipped with a handle on its outer side. This utility model allows the operator to easily grasp and pull the push rod for movement, making it more convenient and labor-saving.

[0010] Each clamping part is fitted with a pressure sleeve on its outer side. The pressure sleeve is made of copper or hard rubber. This utility model can avoid the clamping part directly squeezing the workpiece and causing clamping damage by using the pressure sleeve. This improves the quality of the finished workpiece and reduces unnecessary clamping damage.

[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0012] 1. This utility model can conveniently and quickly adjust the spacing of the clamping plates through the adjustment mechanism, which facilitates the rapid and stable clamping and fixing of workpieces of different diameters, making the operation more convenient.

[0013] 2. This utility model can achieve a firm clamping operation on the workpiece by setting a clamping part at the end of the clamping plate. The shape of the clamping part can be selected and designed according to the shape of the outer contour of the workpiece to be clamped, which makes it more usable and easier to operate.

[0014] 3. This utility model can further adjust the clamping range of the clamping plate by extending the push rod into the guide hole, which further enhances the convenient and quick adjustment of the clamping force for workpieces of different or the same diameter, making the operation more convenient.

[0015] 4. This utility model can lock and fix the top rod after it has been adjusted by tightening the bolts. Moreover, loosening the tightening bolts makes it easy and quick to disassemble the top rod, making the operation more convenient. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0021] As shown in Figures 1-2: This embodiment provides a clamping fixture for stator machining, including a base plate 1100, an adjustment mechanism 200 on the base plate 1100, and a clamping assembly 300 on the adjustment mechanism 200. The clamping assembly 300 includes a pair of clamping plates 301 disposed on the adjustment mechanism 200. The adjustment mechanism 200 can adjust the two clamping plates 301 to move towards each other. The clamping plates 301 are provided with clamping parts 302 that are adapted to the outer side wall of the workpiece to be clamped. This utility model can conveniently and efficiently adjust the two clamping plates 301 towards each other through the adjustment mechanism 200, realize the clamping and fixing operation of stators of various diameters, greatly improve the fixing efficiency in stator machining, and improve the machining quality.

[0022] According to one embodiment of the present invention, as shown in Figures 1 and 3, the adjustment mechanism 200 includes a bidirectional telescopic push rod 201 disposed on the base plate 1100. The bidirectional telescopic push rod 201 is a bidirectional electric push rod or a bidirectional hydraulic push rod. Each output rod end of the bidirectional telescopic push rod 201 is provided with a fixing plate 202, and each fixing plate 202 is provided with a clamping plate 301 on its inner side. The present invention can simultaneously move the fixing plate 202 and the clamping plate 301 away from or towards each other by extending and retracting the output rod of the bidirectional telescopic push rod 201. This not only enables convenient and quick picking and placing of workpieces to be clamped, but also enables clamping and fixing of workpieces of various specifications.

[0023] Another embodiment of the adjustment mechanism 200 includes a slide rail mounted on a base plate 1100. Two sliders with oppositely threaded through holes are slidably mounted inside the slide rail. A bidirectional screw with opposing threads is threaded onto each slider. The bidirectional screw passes through and is threaded onto both sliders. A servo motor is mounted at the end of each screw. A fixing plate 202 is mounted on each slider. This invention can rotate the bidirectional screw by starting the output shaft of the servo motor. Combined with the threaded connection between the bidirectional screw and the two sliders, and the guiding and limiting effect of the slide rail on the two sliders, the rotating bidirectional screw can drive the two sliders, along with the fixing plate 202 and the clamping plate 301 mounted inside the fixing plate 202, to move in opposite directions.

[0024] According to another embodiment of the present invention, as shown in Figure 1, each fixing plate 202 is provided with a guide hole 400, and a push rod 500 is inserted into each guide hole 400. One end of the push rod 500 is fixed to the back of the clamping plate 301 located on the same side. The upper part of the fixing plate 202 is provided with a threaded hole 600 that communicates with the guide cylinder. A clamping bolt 700 is threaded into the threaded hole 600. The present invention can adjust the position of the pressure plate by loosening the clamping bolt 700 and then adjusting the distance of the push rod 500 into the guide hole 400, which greatly increases the clamping adjustment range of the pressure plate and makes it more applicable.

[0025] According to another embodiment of the present invention, as shown in Figures 1 and 3, each top rod 500 is provided with a handle 800 on its outer side. The handle 800 makes it easier for the operator to grip and pull the top rod 500 for movement, making it more convenient and labor-saving.

[0026] Each clamping part 302 is fitted with a pressure sleeve 900 on its outer side. The pressure sleeve 900 is made of copper or hard rubber. This utility model can avoid the clamping part directly squeezing the workpiece and causing clamping damage by using the pressure sleeve 900, thereby improving the quality of the finished workpiece and reducing unnecessary clamping damage.

[0027] How to use this utility model:

[0028] First, it needs to be clarified that the clamping fixture involved in this utility model is mainly used for clamping and fixing various cylindrical workpieces. This utility model takes the clamping and fixing of the stator of a motor as an example to describe its usage method in detail. When it is necessary to clamp and fix the stator of the motor, the operator first adjusts the position of the push rod 500 to a suitable position according to the diameter of the stator. The specific operation is to loosen the clamping bolt 700, grasp the handle and push or pull the push rod 500 inward or outward, moving the clamping plate 301 along the axis of the push rod 500 until it is adjusted to facilitate the smooth placement of the stator into the two clamps. The positioning pins between the plates 301 are inserted, and then the operator places the workpiece to be clamped between the two clamping plates 301. Then, the output rod of the bidirectional telescopic push rod 201 is activated to retract to a suitable length until it pushes the clamping plates 301 inward to clamp and fix the stator. This utility model can conveniently and efficiently adjust the two clamping plates 301 in opposite directions through the adjustment mechanism 200, so as to realize the clamping and fixing operation of stators of various diameters and specifications. It greatly improves the fixing efficiency in stator processing, improves the processing quality, has stronger applicability, and is more convenient to operate.

[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
