Description

Technical Field

[0001] This utility model relates to the field of bushing processing technology, and in particular to a bushing processing clamping device with automatic positioning function. Background Technology

[0002] A bushing is a cylindrical key component fitted around a shaft in mechanical transmission. Its main functions are to reduce direct friction between the shaft and the bearing housing, to achieve shaft positioning and sealing, and to protect the shaft body. Its machining quality directly affects the operating accuracy, stability, and service life of the equipment. It is necessary to first select the right material according to the working conditions, and then gradually improve the accuracy by proceeding from rough machining to semi-finishing and finally to precision machining. Ultimately, by controlling the dimensions, geometric tolerances, and fit requirements, the operating needs of the equipment can be met.

[0003] When machining bushings, they must first be clamped before being machined with a boring bar. Existing bushing machining clamping devices mostly use simple lead screws and clamping blocks for clamping. This clamping process requires rotating the lead screw at multiple angles and manually adjusting it to ensure that the bushing is clamped and positioned in the center, resulting in reduced machining efficiency and decreased practicality.

[0031] 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.

[0032] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 An embodiment of this utility model is provided: a bushing processing clamping device with automatic positioning function, including a positioning ring 1, a positioning mechanism 2 is provided on the top of the positioning ring 1, the positioning mechanism 2 is used for self-positioning and clamping the bushing, and an installation mechanism 3 is fixedly connected to the top of the positioning ring 1, the installation mechanism 3 is used for reinforcing the installation of the entire device.

[0033] The positioning mechanism 2 includes a positioning groove 201, which is located in the middle of the upper and lower sides of the positioning ring 1. Multiple guide blocks 204 are slidably connected to the inner wall of the positioning groove 201. A rotating ring 205 is fixedly connected to the opposite side of the multiple guide blocks 204. A hollow block 207 is fixedly connected to the right side of the positioning ring 1. A limit component 209 is provided on the inner wall of the hollow block 207. A fixing component 206 is fixedly connected to the bottom of the hollow block 207. Multiple balls 212 are fixedly connected to the inner wall of the rotating ring 205. Multiple slide rods 211 are slidably connected to the middle of the inner wall of the positioning ring 1. A clamping ring 203 is fixedly connected to the adjacent end of each slide rod 211. An inclined block 208 is fixedly connected to the opposite end of each slide rod 211. A spring 210 is slidably connected to the middle of the outer wall of the slide rod 211. Multiple auxiliary components 202 are fixedly connected to the inner wall of the positioning groove 201 near the edge.

[0034] Specifically, the auxiliary component 202 provides additional support and stability to ensure the positioning accuracy and clamping effect of the bushing during the machining process. The guide block 204 in the positioning groove 201 ensures that the rotating ring 205 can rotate flexibly, while restricting its movement trajectory, so that it can only rotate within the range specified by the positioning groove 201. When the rotating ring 205 rotates, the ball 212 rotates together, and the surface of the ball 212 interacts with other components in the positioning mechanism 2. Due to the inclined surface structure of the inclined block 208, the squeezing force of the ball 212 on the inclined block 208 will generate a component force along the axial direction of the slide rod 211, thereby pushing the slide rod 211 to move towards the center of the positioning ring 1, and then driving the clamping ring 203 to clamp the bushing.

[0035] Please see the appendix Figure 1 and attached Figure 5The mounting mechanism 3 includes a first flange 301, the top of which is fixedly connected to the bottom of a positioning ring 1. A guide groove 305 is formed on the inner wall of the first flange 301, and a retaining groove 302 is formed on the right side of the inner wall of the guide groove 305. A T-block 304 is slidably connected to the inner wall of the retaining groove 302. A limit screw 303 is threadedly connected to the inner wall of the guide groove 305 near its edge. A second flange 306 is fixedly connected to the bottom of the T-block 304. The inner walls of the first flange 301 and the second flange 306 are near their edges. All parts are threaded with connecting components 307; specifically, during installation, the operator places the T-block 304 into the guide groove 305, and then pushes the second flange 306 to make the T-block 304 slide along the guide groove 305. When the head of the T-block 304 is engaged in the slot 302, the first flange 301 and the second flange 306 achieve preliminary positioning and connection. The main function of the guide groove 305 is to provide guidance for the sliding of the T-block 304, so that the T-block 304 can move smoothly along the predetermined trajectory.

[0036] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 The connecting component 307 includes a bolt 3072, the outer wall of which is threadedly connected to the inner wall of flange 1 301 and flange 2 306, and a nut 3071 is threadedly connected to the outer wall of the bolt 3072 near the edge. The fixing component 206 includes a fixing block 2061, the top of which is fixedly connected to the top of the hollow block 207, and a positioning screw 2062 is threadedly connected to the inner wall of the fixing block 2061. The auxiliary component 202 includes a limiting block 2021, the bottom of which is fixedly connected to the inner wall of the positioning groove 201 near the edge. A friction pad 2022 is fixedly connected to the outer wall of the clamping ring 203.

[0037] Specifically, during the tightening of nut 3071, the friction between nut 3071 and the surface of flange 306, and the axial tension of bolt 3072, cause the two flanges to be tightly pressed together. By rotating the positioning screw 2062, it moves back and forth in the inner wall of the fixing block 2061, allowing it to be inserted into the corresponding structure. The friction pad 2022 has a certain buffering effect, which can reduce the damage to the bushing surface during clamping and protect the processing quality of the bushing.

[0038] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3The outer wall of the locking block 2094 is in contact with the outer wall of the pin 2093. The middle part of the inner wall of the slide groove 2091 is slidably connected to the outer wall of the rotating ring 205. The outer wall of the limiting screw 303 is in contact with the outer wall of the T-block 304. The bottom of the flange 1 301 is in contact with the top of the flange 2 306. The limiting component 209 includes the slide groove 2091, which is located in the middle part of the inner wall of the hollow block 207. Limiting grooves 2092 are provided on the upper and lower sides of the inner wall of the slide groove 2091. The pin 2093 is slidably connected to the inner wall of the limiting groove 2092. Multiple locking blocks 2094 are fixedly connected to the outer wall of the rotating ring 205.

[0039] Specifically, the slide groove 2091 provides a track for the movement of the rotating ring 205, the pin 2093 can slide in a specific direction within the limiting groove 2092, and its function is to limit the movement range of the rotating ring 205. The function of the locking block 2094 is to transmit the movement of the rotating ring 205 to the pin 2093, thereby limiting the rotation of the rotating ring 205 by limiting the locking block 2094. The limiting screw 303 can limit the sliding position of the T-block 304.

[0040] Working principle: When the adjustment device needs to clamp the bushing, first rotate the rotating ring 205 to make the ball 212 rotate together, which in turn squeezes the inclined block 208, thereby pushing the slide rod 211 to squeeze the clamping ring 203 in the center. Since multiple clamping rings 203 move in the center at the same time, the bushing placed between multiple clamping rings 203 is positioned towards the center. When the appropriate clamping position is reached, insert the pin 2093 into the limiting groove 2092, thereby engaging with multiple locking blocks 2094 to limit the rotating ring 205. Finally, rotate the positioning screw 2062 to connect the pin 2093 and the fixing block 2061 for multiple limiting. When unlocking, simply pull the pin 2093 out of the limiting groove 2092, and then the spring 210 will push the inclined block 208 to move the slide rod 211 outward to contact the clamping and positioning.

[0041] When installing the device on a machining machine, firstly, flange 2 306 is connected to the machining shaft in a specified manner. Then, guide groove 305 is aligned with T-block 304, so that T-block 304 is inserted into guide groove 305 while the bottom of flange 1 301 and the top of flange 2 306 are in contact. Then, flange 1 301 is rotated so that the top of T-block 304 can be inserted into slot 302. Then, limit screw 303 is rotated so that it can be inserted into guide groove 305 and prevent T-block 304 from sliding out of slot 302. Finally, bolt 3072 is inserted so that it passes through flange 1 301 and flange 2 306, and nut 3071 is rotated to position it. During machining rotation, even if bolt 3072 and nut 3071 loosen and fall off due to shaking and vibration during machining, limit screw 303 can still ensure that the fixture will not fall off directly and cause personal injury.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
