Description

Technical Field

[0002] During the production of elevator accessories, grinding can make the surface of the accessories reach higher precision and smoothness, ensuring the running precision, stability and safety after the accessories are assembled. There are many conical accessories in elevator accessories, such as conical guide rail sliders, conical bearing seats, etc.

[0003] When the existing grinding device for the production of elevator accessories is in use, when it grinds conical accessories, due to the lack of a profiling and adaptive function, it is difficult for the grinding belt to accurately fit the inclination angle of the conical surface, and the running track of the grinding belt cannot be dynamically adjusted according to the slope of the conical surface, resulting in a non-parallel state with the conical surface all the time. This non-parallel grinding state will cause differences in the grinding pressure and grinding stroke in different areas of the conical accessory surface, and then cause uneven surface grinding, resulting in problems such as local over-grinding or insufficient grinding, seriously affecting the surface precision of the accessory. At the same time, when facing accessories with different taper specifications, it is necessary to frequently replace the grinding tooling or adjust the equipment parameters, which is cumbersome to operate and has poor adaptability, resulting in low overall grinding efficiency and low practicality.

The grinding mechanism 4 includes a displacement seat b 401, a roller frame 402, two driving rollers 403, a grinding belt 404, and a driving motor 405. The displacement seat b 401 is inserted inside the rail base 201, and the roller frame 402 is rotatably connected to the bottom of the displacement seat b 401. The two driving rollers 403 are rotatably connected inside the roller frame 402, and the grinding belt 404 is installed outside the two driving rollers 403. The driving motor 405 is fixedly installed on the side of the displacement seat b 401. The grinding assembly further includes a synchronizing mechanism 5. There are two sets of the synchronizing mechanism 5, and the two sets of the synchronizing mechanism 5 are symmetric to each other. The synchronizing mechanism 5 includes a connecting seat 501, a control swing rod 502, a synchronizing block 503, and a linkage block 504. The connecting seats 501 of the two sets of the synchronizing mechanism 5 are respectively fixedly connected to the sides of the displacement seat a 301 and the displacement seat b 401. The control swing rod 502 is rotatably connected inside the connecting seat 501. The synchronizing block 503 is rotatably connected inside the connecting seat 501, and the linkage block 504 is inserted inside the connecting seat 501. The synchronizing mechanism 5 located on the side of the displacement seat a 301 is the driving mechanism, and the synchronizing mechanism 5 located on the side of the displacement seat b 401 is the driven mechanism.

[0035] Among them, the profiling mechanism 3 and the grinding mechanism 4 are symmetrically arranged on both sides of the clamping center of the positioning chuck 103. A driving gear 4051 is provided on the side of the driving motor 405. The driving gear 4051 and the rotating shaft of the roller frame 402 are on the same axis. A grinding gear 4031 is provided at the top of the rotating shaft of one of the transmission rollers 403. The grinding gear 4031 and the driving gear 4051 are in meshing transmission. This design enables the grinding gear 4031 and the driving gear 4051 to always be in meshing transmission regardless of how the use angle of the roller frame 402 changes, ensuring the stability of the grinding process. The conical fittings of the elevator can be positioned and fixed through the positioning chuck 103, facilitating the subsequent grinding operation of the fittings by the grinding assembly. The telescopic movement of the electric push rod 102 can drive the overall lifting of the grinding assembly. By controlling the lowering of the grinding assembly, the grinding belt 404 can be abutted against the side of the conical fitting for grinding. When the driving motor 405 rotates, the driving gear 4051 of the driving motor 405 can drive one of the transmission rollers 403 to rotate through the grinding gear 4031. Thus, under the combined action of the two transmission rollers 403 and the grinding belt 404, the grinding belt 404 can move cyclically and perform grinding operations on the surface of the conical fitting, which is convenient and flexible to use.

[0036] Among them, a contact roller 3021 is provided on the side of the profiling arm 302, and a return torsion spring is provided outside the rotating shaft of the profiling arm 302. Under the action of the return torsion spring, when the profiling arm 302 and the contact roller 3021 are not externally contacted and squeezed, the profiling arm 302 is in a vertical state. During use, the grinding assembly has the profiling function for the conical fitting, thereby adaptively adjusting the grinding angle according to the inclination of the conical surface, ensuring that the grinding belt 404 is always parallel to the grinding surface, and improving the quality of the grinding process. Under the action of the return torsion spring, the profiling arm 302 is in a vertically downward state, and the profiling arm 302 can make the roller frame 402 also in a vertically downward state through two sets of synchronization mechanisms 5. When the grinding assembly moves downward, the contact roller 3021 of the profiling arm 302 will contact the surface of the conical fitting. Under the action of the contact and extrusion on the surface of the conical fitting, the profiling arm 302 will rotate to adapt to the surface inclination of the conical fitting, and the displacement seat a301 will move to one side to avoid and compress the return top spring 3012, which can prevent the device from jamming. The profiling mechanism 3 can control the state of the grinding mechanism 4 through the above actions, thereby realizing the function of profiling grinding.

[0037] Among them, moving protrusions 3011 are provided inside both the displacement seat a301 and the displacement seat b401, and a moving groove 2021 with a spiral trend is provided on the outside of the positioning rod 202. The moving groove 2021 has two sections, and the two sections of the moving groove 2021 are symmetrical to each other. The moving protrusions 3011 of the displacement seat a301 and the displacement seat b401 are respectively inserted into the two sections of the moving groove 2021. Return springs 3012 are provided on the sides of both the displacement seat a301 and the displacement seat b401. The two ends of one of the return springs 3012 respectively abut against the inside of the track seat 201 and the side of the displacement seat a301, and the two ends of the other return spring 3012 respectively abut against the inside of the track seat 201 and the side of the displacement seat b401. During use, when the displacement seat a301 moves, the moving protrusion 3011 inside it can drive the positioning rod 202 to rotate through the moving groove 2021. When the positioning rod 202 rotates, the moving groove 2021 can drive the displacement seat b401 to move synchronously through the moving protrusion 3011 of the displacement seat b401, and the moving directions of the displacement seat b401 and the displacement seat a301 are opposite, realizing a profiling action in the horizontal position.

[0038] Among them, the synchronization mechanism 5 further includes a reversing gear 505, and the reversing gear 505 is rotatably connected inside the connecting seat 501. By means of the reversing gear 505, the swinging direction of the control swing rod 502 during transmission can be changed, so that the swinging direction of the control swing rod 502 is an outward swing. This design can avoid the phenomenon of interference between the two control swing rods 502 when the two synchronization mechanisms 5 perform profiling control, and the use is stable. Wherein, a connecting gear 5022 is provided outside the rotating shaft of the control swing rod 502, and control gears 3022 are provided outside the rotating shafts of the profiling arm 302 and the roller frame 402 respectively. Both sides of the reversing gear 505 of the driving mechanism are meshed with the teeth of the control gear 3022 of the profiling arm 302 and the teeth of the connecting gear 5022 of the control swing rod 502 of the driving mechanism respectively. Both sides of the reversing gear 505 of the driven mechanism are meshed with the teeth of the control gear 3022 of the roller frame 402 and the teeth of the connecting gear 5022 of the control swing rod 502 of the driven mechanism respectively. A linkage slot 5021 is provided inside the control swing rod 502, and a linkage rod 5041 is provided on the side surface of the linkage block 504. The linkage rod 5041 is inserted into the inside of the linkage slot 5021. A conversion protrusion 5042 is provided inside the linkage block 504, and a conversion slot 5031 with a spiral shape is provided outside the synchronizing block 503. The conversion protrusion 5042 is inserted into the inside of the conversion slot 5031. The cross-sectional shape of the rod body of the synchronizing rod 203 is a regular polygon. A synchronizing slot 5032 is provided inside the synchronizing block 503. The rod body part of the regular polygon cross-section of the synchronizing rod 203 is inserted into the inside of the synchronizing slot 5032. During use, when the profiling arm 302 rotates to adapt to the surface inclination of the tapered fitting, the following actions will occur inside the driving mechanism: the control gear 3022 of the profiling arm 302 can drive the reversing gear 505 of the driving mechanism to rotate. When the reversing gear 505 rotates, it can drive the control swing rod 502 to rotate through the connecting gear 5022. When the control swing rod 502 rotates, the linkage slot 5021 can drive the linkage block 504 to move outwards (in the direction away from the tapered fitting) through the linkage rod 5041. When the linkage block 504 moves, the conversion protrusion 5042 can drive the synchronizing block 503 to rotate through the conversion slot 5031. When the synchronizing block 503 rotates, it can drive the synchronizing rod 203 to rotate through the synchronizing slot 5032. At the same time, the following actions will occur inside the driven mechanism: when the synchronizing rod 203 rotates, it can drive the synchronizing block 503 of the driven mechanism to rotate through the synchronizing slot 5032. When the synchronizing block 503 rotates, it can drive the linkage block 504 to move outwards. When the linkage block 504 moves, it can drive the control swing rod 502 to rotate. When the control swing rod 502 rotates, it can drive the roller frame 402 to rotate through the reversing gear 505. Due to the above actions, the rotating directions of the profiling arm 302 and the roller frame 402 are also opposite, and the rotating angles of the profiling arm 302 and the roller frame 402 are the same, thus realizing the profiling control function of the use angle of the grinding belt 404 through the profiling arm 302. The grinding belt 404 can always be parallel to the surface of the tapered fitting during grinding, improving the grinding quality. The profiling arm 302 can adaptively adjust its own angle according to the inclination of the tapered fitting, so that the roller frame 402 can also be synchronously adjusted, and it can adapt to the rapid grinding processing of different types of tapered fittings.

[0039] Specific usage method and function of this embodiment: In the present invention, the conical fitting of the elevator can be positioned and fixed through the positioning chuck 103. The positioning chuck 103 can drive the conical fitting of the elevator to rotate self - adaptively to realize the overall grinding operation, which is convenient for the subsequent grinding operation of the grinding component on the fitting. The telescopic movement of the electric push rod 102 can drive the overall lifting of the grinding component. By controlling the descent of the grinding component, the grinding belt 404 can be abutted against the side surface of the conical fitting for grinding operation. When the drive motor 405 rotates, the drive gear 4051 of the drive motor 405 can drive one of the transmission rollers 403 to rotate through the grinding gear 4031. Thus, under the combined action of the two transmission rollers 403 and the grinding belt 404, the grinding belt 404 can move cyclically and perform grinding operation on the surface of the conical fitting. The grinding component has a profiling function for the conical fitting, so as to adaptively adjust the grinding angle according to the inclination of the conical surface, ensuring that the grinding belt 404 is always parallel to the grinding surface and improving the quality of the grinding operation. Under the action of the reset torsion spring, the profiling arm 302 is in a vertically downward state, and the profiling arm 302 can make the roller frame 402 also in a vertically downward state through the two sets of synchronization mechanisms 5. When the grinding component moves downward, the contact roller 3021 of the profiling arm 302 will contact the surface of the conical fitting. Under the contact extrusion action on the surface of the conical fitting, the profiling arm 302 will rotate to adapt to the surface inclination of the conical fitting, and the displacement seat a301 will move to one side to avoid and compress the reset top spring 3012, which can prevent the device from jamming. The profiling mechanism 3 can realize the state control of the grinding mechanism 4 through the above actions. When the displacement seat a301 moves, the moving protrusion 3011 inside it can drive the positioning rod 202 to rotate through the moving groove 2021. When the positioning rod 202 rotates, the moving groove 2021 can drive the displacement seat b401 to move synchronously through the moving protrusion 3011 of the displacement seat b401, and the moving directions of the displacement seat b401 and the displacement seat a301 are opposite, realizing the profiling action in the horizontal position. When the profiling arm 302 rotates to adapt to the surface inclination of the conical fitting, the following actions will occur inside the active mechanism: The control gear 3022 of the profiling arm 302 can drive the reversing gear 505 of the active mechanism to rotate. When the reversing gear 505 rotates, it can drive the control swing rod 502 to rotate through the connecting gear 5022. When the control swing rod 502 rotates, the linkage groove 5021 can drive the linkage block 504 to move outward (away from the conical fitting) through the linkage rod 5041. When the linkage block 504 moves, the conversion protrusion 5042 can drive the synchronizing block 503 to rotate through the conversion groove 5031. When the synchronizing block 503 rotates, it can drive the synchronizing rod 203 to rotate through the synchronizing groove 5032;Meanwhile, the following actions occur inside the driven mechanism: When the synchronizing rod 203 rotates, it can drive the synchronizing block 503 of the driven mechanism to rotate through the synchronizing groove 5032. When the synchronizing block 503 rotates, it can drive the linkage block 504 to move outwards. When the linkage block 504 moves, it can drive the control swing rod 502 to rotate. When the control swing rod 502 rotates, it can drive the roller frame 402 to rotate through the reversing gear 505; Due to the above actions, the rotation directions of the profiling arm 302 and the roller frame 402 are also opposite, and the rotation angles of the profiling arm 302 and the roller frame 402 are the same, thus realizing the profiling control function of the use angle of the grinding belt 404 through the profiling arm 302. The grinding belt 404 can always be parallel to the surface of the conical fitting during grinding. The profiling arm 302 can adaptively adjust its own angle according to the inclination of the conical fitting, so that the roller frame 402 can also be synchronously controlled, enabling rapid grinding of different types of conical fittings.;
