Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, specifically a stepper motor machining fixture. Background Technology

[0002] Fixtures play a vital role in modern industrial production. A fixture is a device used in the mechanical manufacturing process to fix a workpiece in the correct position for operation or inspection. Fixtures ensure the positioning accuracy of the workpiece during processing, thereby improving production efficiency. Fixtures are widely used in various fields such as machinery manufacturing, automobile manufacturing, aerospace, and electronics. As an important device in the mechanical manufacturing process, the technical level of fixtures directly affects product quality and production efficiency. With the continuous development of industrial technology, fixture technology is also constantly innovating and progressing to adapt to increasingly complex production needs.

[0003] For example, the stepper motor processing fixture disclosed in Chinese Patent Publication No. CN209998808U includes a base. One side of the base is bolted to the lower end of a support plate. The upper end of the support plate is connected to a pressure plate via a rotating shaft. A support body for supporting the stepper motor is located at the center plane of the base, and a through hole for mounting a ball screw is located at the center of the support body. This stepper motor processing fixture can be used for auxiliary processing of stepper motors. The space between the upper plane of the base and the pressure plate is used to place the motor for mounting the upper part of the motor. The lower plane of the base is used for connecting the motor to the lower rod. The entire fixture is bolted to the processing table through fixing screw holes at both ends of the base. The overall structure is simple and provides excellent auxiliary processing results.

[0004] The above description describes clamping the motor frame of the stepper motor and then manually inserting the rotor into the motor frame. This operation cannot achieve accurate positioning during insertion and will also cause wear on the rotor surface, thus affecting subsequent use. Therefore, a stepper motor processing fixture is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a stepper motor processing fixture to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stepper motor processing fixture, comprising a fixture body, a motor frame, a rotor and a rotating shaft provided on the fixture body, a second support plate for placing the rotor being slidably mounted on the top of the fixture body, and a roller being installed at the end of the second support plate, a placement groove corresponding to the second support plate being opened on the side wall of the fixture body, a spring being installed at the end of the second support plate, and a telescopic rod corresponding to the spring being installed at the end of the second support plate;

[0007] A baffle is installed on the top of the fixture body, and a sleeve corresponding to the rotating shaft is fixedly installed inside the baffle. A guide block corresponding to the sleeve is installed on the outer wall of the baffle to guide the rotating shaft.

[0008] A first support plate for placing a motor frame is slidably mounted on the top of the fixture body, and a slider is mounted on the bottom of the first support plate. A lead screw that is threadedly connected to the slider is mounted inside the top of the fixture body, and a drive assembly corresponding to the lead screw is mounted inside the fixture body.

[0009] By adopting the above technical solution, the rotor can be guided by the guide block during installation, thus inserting it well into the sleeve. After the rotor is installed, it is supported by the second support plate, which prevents the rotor from shaking and ensures a perfect combination between the rotor and the motor frame. Under the action of the first support plate, the combination of the motor frame and the rotor can be carried out smoothly. After the motor frame and the rotor are combined, the second support plate can be reset by the spring and the telescopic rod, which will not affect the next use.

[0010] Furthermore, the sleeve is cylindrical, and the inner diameter of the sleeve corresponds to the outer diameter of the shaft.

[0011] By adopting the above technical solution, the rotor can be installed and, after installation, can play a fixing role.

[0012] Furthermore, the guide block is V-shaped, and the horizontal plane at the top of the guide block opening is higher than the horizontal plane at the top of the sleeve.

[0013] By adopting the above technical solution, the rotor can be better inserted into the sleeve during installation, without causing wear on the shaft.

[0014] Furthermore, the two sides of the bottom end of the first support plate are located inside the limiting groove, and the distance between the outer walls of the bottom end of the first support plate is less than the distance between the inner walls of the limiting groove.

[0015] By adopting the above technical solution, the motor frame can move smoothly during the movement process.

[0016] Furthermore, the spring and the telescopic rod are fixedly installed between the second support plate and the placement groove, and the length of the spring corresponds to the length of the telescopic rod, and the outer diameter of the telescopic rod is smaller than the inner diameter of the spring.

[0017] By adopting the above technical solution, the second support plate will not be misaligned during the movement process, and the second support plate can be reset after the motor frame is combined with the rotor.

[0018] Furthermore, the depth of the placement groove corresponds to the length of the second support plate, and the horizontal plane at the top of the placement groove corresponds to the horizontal plane at the top of the roller.

[0019] By adopting the above technical solution, the second support plate can be fully inserted into the placement slot when moving, without affecting the connection between the motor frame and the rotor.

[0020] Furthermore, the second support plate is sleeved on the outer wall of the lead screw, and the inner diameter of the through hole at the end of the second support plate is larger than the outer diameter of the lead screw.

[0021] By adopting the above technical solution, the second support plate is limited when it moves, without affecting the normal use of the lead screw.

[0022] Furthermore, the distance between the inner walls of the first support plate ends is less than the distance between the outer walls of the motor frame.

[0023] By adopting the above technical solution, the motor frame can be limited during movement and will not fall off the support plate.

[0024] In summary, the present invention has the following main advantages:

[0025] This utility model is equipped with a lead screw, a slider, a first support plate, a second support plate, and a sleeve. When using the fixture body, the rotor is inserted into the sleeve through the guide block. Under the action of the second support plate, the rotor can be kept in a horizontal state. Under the action of the first support plate and the limiting groove, the motor frame can move smoothly when moving. Under the action of the limiting plate, the motor will not shake when moving. At this time, the servo motor is started, and under the action of the lead screw, the motor frame moves slowly until the rotor is completely inserted into the motor frame.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] A stepper motor machining fixture, such as Figure 1 - Figure 5 As shown, the fixture includes a main body 1, on which a motor frame 6, a rotor 8, and a rotating shaft 81 are mounted. A second support plate 7 for placing the rotor 8 is slidably mounted on the top of the main body 1 to support the rotor 8 and prevent it from wobbling after installation. A roller 71 is mounted on the end of the second support plate 7 to prevent wear on the rotor 8 when the second support plate 7 moves. A placement groove 12 corresponding to the second support plate 7 is opened on the side wall of the fixture body 1 so that the rotor 8 can be better connected with the motor frame 6. A spring 72 is mounted on the end of the second support plate 7, and a telescopic rod 73 corresponding to the spring 72 is mounted on the end of the second support plate 7 so that the second support plate 7 can be reset after movement and will not affect the next use.

[0035] A baffle 2 is installed on the top of the fixture body 1, and a sleeve 21 corresponding to the rotating shaft 81 is fixedly installed inside the baffle 2, which enables the rotating shaft 81 to be installed. A guide block 22 corresponding to the sleeve 21 is installed on the outer wall of the baffle 2 to guide the rotating shaft 81.

[0036] A first support plate 51 for placing the motor frame 6 is slidably mounted on the top of the fixture body 1, which can limit and fix the motor frame 6. A slider 5 is installed at the bottom of the first support plate 51, and a lead screw 4 that is threadedly connected to the slider 5 is installed inside the top of the fixture body 1. A drive component corresponding to the lead screw 4 is installed inside the fixture body 1, which makes it easier for the motor frame 6 to be combined with the rotor 8.

[0037] Please see Figure 2 The sleeve 21 is cylindrical, and the inner diameter of the sleeve 21 corresponds to the outer diameter of the shaft 81, which allows the shaft 81 to be better installed inside the sleeve 21.

[0038] Please see Figure 2 The guide block 22 is V-shaped, and the horizontal plane at the top of the opening of the guide block 22 is higher than the horizontal plane at the top of the sleeve 21, which can guide the installation of the rotating shaft 81, making the installation more convenient and quick.

[0039] Please see Figure 4 and Figure 5 The bottom sides of the first support plate 51 are located inside the limiting groove 11, and the distance between the outer walls of the bottom of the first support plate 51 is less than the distance between the inner walls of the limiting groove 11, so that the motor frame 6 can move smoothly during the movement and the motor frame 6 will not shake.

[0040] Please see Figure 2 The spring 72 and the telescopic rod 73 are fixedly installed between the second support plate 7 and the placement groove 12, which enables the second support plate 7 to move smoothly. The length of the spring 72 corresponds to the length of the telescopic rod 73, and the outer diameter of the telescopic rod 73 is smaller than the inner diameter of the spring 72, so that the spring 72 will not be damaged during the movement.

[0041] Please see Figure 4 and Figure 5 The depth of the placement groove 12 corresponds to the length of the second support plate 7, so that the second support plate 7 can be fully retracted without affecting the installation of the motor frame 6 and the rotor 8, and the horizontal plane at the top of the placement groove 12 corresponds to the horizontal plane at the top of the roller 71.

[0042] Please see Figure 3 The second support plate 7 is sleeved on the outer wall of the lead screw 4, and the inner diameter of the through hole at the end of the second support plate 7 is larger than the outer diameter of the lead screw 4, so that the second support plate 7 can be limited when moving, and will not affect the normal use of the lead screw 4.

[0043] Please see Figure 4 and Figure 5 The distance between the inner walls of the first support plate 51 is less than the distance between the outer walls of the motor frame 6, so that the motor frame 6 will not fall during movement and can move smoothly.

[0044] The working principle of this utility model is as follows: When using the fixture body 1, the rotor 8 and the rotating shaft 81 are first inserted into the sleeve 21 through the guide block 22. The second support plate 7 and the roller 71 keep the rotor 8 in a horizontal state and prevent the rotor 8 from wobbling up and down. When the motor frame 6 is first combined with the rotor 8, the servo motor 3 is started, which drives the lead screw 4 to rotate. At this time, the slider 5 also moves. Because the first support plate 51 slides in the internal limiting groove 11, the motor frame 6 can move smoothly during the movement. Under the action of the first support plate 51, the motor frame 6 will not wobble. When the motor frame 6 slowly combines with the rotor 8 and the rotating shaft 81, the second support plate 7 will slowly reduce its support for the rotor 8. Under the action of the roller 71, the surface of the rotor 8 will not be worn, so that the rotor 8 can better combine with the motor frame 6. When the rotor 8 is completely inside the motor frame 6, the motor frame 6 returns to its original position under the action of the lead screw 4. At this time, under the action of the spring 72 and the telescopic rod 73, the second support plate 7 is reset, preparing for the next use.
