Description

Technical Field

[0001] The present invention relates to the field of bearing processing, and specifically to an outer ring clamping seat for bearing processing. Background Technique

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical loads during the transmission design of the equipment. A bearing is a component that fixes and reduces the friction coefficient during the development of mechanical transmission. It can also be said that when other parts on the shaft move relative to each other, it is used to reduce the friction coefficient during the power transmission process and keep the center position of the shaft fixed; During the process of bearing processing, in order to avoid the bearing from shifting and causing processing misalignment, clamping tools are usually required to fix the bearing.

[0003] The existing Chinese published patent document: CN112122974B discloses a clamping device for copper sleeve bearing processing. By starting the hydraulic cylinder, the piston rod pushes the active rod to act on the pressing plate, so that the pressing plate fits on the side wall of the bearing. At the same time, the spur gear rotates under the push of the active rod, so that a set of pressing plates are successively driven on the left clamping arm and the right clamping arm to act on the bearing, so that the bearing can be stably and effectively clamped, providing a good operating basis for subsequent processing; However, when the above clamping device is in use, the pressing plate pushes the bearing onto the two clamping arms. When the bearing contacts the two clamping arms, inertia will be generated, and it is difficult to control the clamping force, which easily causes the bearing to break and affects bearing processing. For this reason, we propose an outer ring clamping seat for bearing processing. Summary of the Invention

[0020] Please refer to Figures 2 - 6, in the illustration, the clamping mechanism 3 includes a driven rod 301 rotatably mounted on the top of the base 1. The driven rod 301 extends into the interior of the housing 2. A motor 302 is fixedly mounted on the outer side of the housing 2. The output end of the motor 302 extends into the interior of the housing 2. Conical wheels 303 are fixedly connected to the output end of the motor 302 and the outer side of the driven rod 301 respectively. The two conical wheels 303 mesh with each other. One end of the driven rod 301 is fixedly connected to a threaded rod 304. A cross push rod 305 is sleeved on the outer side of the threaded rod 304. Corresponding internal threads are provided in the interior of the cross push rod 305 and on the outer side of the threaded rod 304. A cross slide rod 306 is fixedly connected to the inner wall of the housing 2. The end of the threaded rod 304 away from the driven rod 301 is fixedly mounted on the bottom of the cross slide rod 306. Four equally spaced sleeve ones 307 are sleeved on the outer side of the cross push rod 305. Four equally spaced sleeve twos 308 are sleeved on the outer side of the cross slide rod 306. Both the sleeve one 307 and the sleeve two 308 are hollow square tube structures. A pull rod one 309 is fixedly mounted between the sleeve one 307 and the sleeve two 308. A pull rod two 310 is fixedly mounted on the side of the sleeve one 307 away from the pull rod one 309. One end of the pull rod two 310 is fixedly mounted on a positioning block 311. The positioning block 311 is fixedly connected to the inner wall of the housing 2 and the bottom of the processing flat plate 6. A slide bar 312 is fixedly connected to the top of the sleeve two 308. A guiding groove 313 for the slide bar 312 to slide and be limited is provided on the top of the processing flat plate 6. A baffle 314 is fixedly connected to the top of the slide bar 312. One end of the baffle 314 close to the center of the processing flat plate 6 is beveled. A clamping rod 7 is rotatably mounted on the top of the baffle 314. The width and length of the baffle 314 are both greater than those of the guiding groove 313. Four limiting blocks 315 annularly distributed on the outer side of the cross push rod 305 are fixedly connected to the bottom inner wall of the housing 2. The outer side of the limiting block 315 is in contact with the outer side of the cross push rod 305. The user places the bearing on the processing flat plate 6 and starts the motor 302. The motor 302 drives the driven rod 301 to rotate through the two conical wheels 303. The driven rod 301 drives the threaded rod 304 to rotate. Through the internal thread of the cross push rod 305 and the four limiting blocks 315, the cross push rod 305 is driven to move upward. The cross push rod 305 drives the four sleeve ones 307 to move synchronously. When the sleeve one 307 moves upward, the pull rod two 310 is driven to rotate with the positioning block 311 as the fulcrum. Thus, the sleeve one 307 can move along the outer wall of the cross push rod 305. The sleeve one 307 can push the sleeve two 308 to move along the outer wall of the cross slide rod 306 through the pull rod one 309. The sleeve two 308 drives the slide bar 312 to move along the guiding groove 313 on the top of the processing flat plate 6. The slide bar 312 can drive the clamping rod 7 to move towards the outer wall of the bearing through the baffle 314. Furthermore, the four clamping rods 7 move towards the outer wall of the bearing synchronously, pressing the roller 8 against the outer wall of the bearing, thereby achieving the effect of quickly clamping and fixing the bearing.

[0021] Please refer to Figure 6, in the illustration, the material receiving mechanism 4 includes four mounting slots 401 equidistantly opened at the top of the processing flat plate 6. The mounting slots 401 are located between two adjacent guiding slots 313. A material receiving box 402 is inserted and limited in the inner wall of the mounting slot 401. The material receiving box 402 extends into the interior of the housing 2. A clamping strip 403 is fixedly connected to the top of the material receiving box 402. The inner wall of the clamping strip 403 is of an inclined surface structure. A groove for the clamping strip 403 to be inserted and limited is opened in the inner wall of the mounting slot 401. A lifting groove 404 is opened in the interior of the material receiving box 402. The bottom of the lifting groove 404 is of an inclined surface structure. After the bearing processing is completed, the scraps can be pushed into the material receiving box 402, and the material receiving box 402 can be taken out through the lifting groove 404, improving the cleanliness of the surface of the processing flat plate 6 and proceeding to process the next bearing.

[0022] Please refer to Figure 7 , in the illustration, the adjusting mechanism 5 includes a support base 501 mounted at the bottom of the base 1. A mounting rod 502 is fixedly installed on the axis between the inner wall of the support base 501 and the base 1. A ratchet wheel 503 is sleeved on the outer side of the mounting rod 502. A groove for the installation of the ratchet wheel 503 is opened at the bottom of the support base 501. The top of the ratchet wheel 503 is fixedly installed at the bottom of the base 1. A snap ring 504 is sleeved on the ratchet bar of the ratchet wheel 503. A number of positioning rods 505 are fixedly installed on the axis of the inner wall of the snap ring 504 at equal intervals. Two symmetrically distributed discs 506 are sleeved on the outer side of the positioning rods 505. An insertion bar 507 is fixedly connected between the two discs 506. The outer side of the insertion bar 507 is of a right trapezoidal structure. The insertion bar 507 is inserted into the ratchet bar of the ratchet wheel 503. The right angle surface of the insertion bar 507 is in contact with the right angle surface of the ratchet bar of the ratchet wheel 503. A coil spring 508 is fixedly connected to the outer side of the insertion bar 507. The coil spring 508 is sleeved on the outer side of the positioning rod 505 and is located between the two discs 506. The user can rotate the housing 2 to drive the ratchet wheel 503 on the base 1 to rotate, so that the inclined surface of the ratchet bar of the ratchet wheel 503 is in contact with the inclined surface of the insertion bar 507, pushing the insertion bar 507 to rotate along the outer wall of the positioning rod 505 and compressing the coil spring 508. When the user stops rotating the housing 2, the coil spring 508 resets and drives the insertion bar 507 to re-insert into the rack of the ratchet wheel 503 to fix the base 1, preventing the user from offsetting during the bearing processing.

[0023] Working principle of the stable bearing clamp: First, the user places the bearing on the processing flat plate 6 so that the bearing is located between the four clamping rods 7. Subsequently, the user starts the motor 302, and the output end of the motor 302 drives the driven rod 301 to rotate through two conical wheels 303. The driven rod 301 drives the threaded rod 304 to rotate synchronously. Through the internal thread of the cross push rod 305 and the four limit blocks 315, the cross push rod 305 is driven to move upward, and the cross push rod 305 drives the four sleeves 307 to move synchronously. The sleeve 307 drives the pull rod 310 to rotate with the positioning block 311 as the fulcrum, thereby reversely pushing the sleeve 307 to move along the outer wall of the cross push rod 305. The sleeve 307 pushes the sleeve 308 to move along the outer wall of the cross slide bar 306 through the pull rod 309. Furthermore, the sleeve 308 drives the slide bar 312 to move along the guide groove 313 on the top of the processing flat plate 6. The slide bar 312 drives the clamping rod 7 to move towards the outer wall of the bearing through the baffle 314. Using the inclined surface of the baffle 314, the baffle 314 is inserted into the bottom of the bearing, and the four clamping rods 7 move synchronously towards the outer wall of the bearing, pressing the rollers 8 against the outer wall of the bearing, thus achieving the effect of quickly clamping and fixing the bearing; During processing, when the user needs to adjust the horizontal angle of the bearing, the outer shell 2 can be driven to drive the base 1 to rotate along the surface of the support seat 501. The ratchet wheel 503 driven by the base 1 rotates synchronously. The inclined surface of the ratchet bar of the ratchet wheel 503 contacts the inclined surface of the insertion bar 507, pushing the insertion bar 507 to rotate along the outer wall of the positioning rod 505 and compressing the coil spring 508. After adjusting the processing flat plate 6 to the required horizontal angle, the user stops rotating the outer shell 2. The coil spring 508 resets and drives the insertion bar 507 to re-insert into the rack of the ratchet wheel 503 to lock the base 1, thus achieving the effect of improving the convenience of bearing processing; After processing, the user takes out the bearing and pushes the scraps into the material collection box 402 to keep the surface of the processing flat plate 6 clean. The material collection box 402 can be pulled out of the installation slot 401 through the lifting groove 404 to clean the scraps, which is convenient for processing the next bearing. Embodiment 2

The end of the resisting rod 11 away from the resisting block 12 is fixedly connected with a limiting plate 14. The outer diameter of the limiting plate 14 is larger than the outer diameter of the resisting rod 11.

[0026] In this embodiment: When the clamping rod 7 abuts against the outer side of the bearing, the roller 8 at one end of the clamping rod 7 is in contact with the outer wall of the bearing. The clamping rod 7 is subjected to pressure, rotates with the connection point between the clamping rod 7 and the baffle 314 as the fulcrum, and comes into contact with the resisting block 12. The resisting block 12 compresses the spring 13 to provide buffering for the clamping rod 7, so that the roller 8 at the other end of the clamping rod 7 stably contacts the outer wall of the bearing, improving the clamping stability of the clamping rod 7 on the bearing and preventing damage caused by excessive force.
