Description

Technical Field

[0001] The utility model relates to the technical field of grinding processing equipment, in particular to a grinding equipment for processing elevator bearings. Background Art

[0002] Tapered roller bearings are separable bearings. Both the inner and outer rings of the bearings have tapered raceways. This type of bearing is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed. Single-row tapered roller bearings can withstand radial loads and axial loads in a single direction. During the production and processing of existing tapered roller bearings, it is necessary to remove excess material from their surfaces, and the commonly used method is grinding, which can achieve a higher surface roughness.

[0003] During the loading process, the existing grinding equipment for elevator bearing processing generally directly hooks the bearing body with a rotating rod for rotation. After hooking, one side of the bearing and the equipment are rubbed during the rotation process. Over a long period of time, this friction will not only cause damage to the bearing surface, but also seriously wear the outer casing of the equipment, thereby affecting the overall performance and service life of the equipment. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a grinding device for elevator bearing processing to solve the technical problem that friction may seriously wear the outer shell of the device.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grinding device for elevator bearing processing, the working side of the grinding device is provided with a driving spindle and a grinding wheel, as well as a loading plate and a transmission mechanism, wherein the transmission mechanism includes: a connecting plate that rotates with the grinding device through a telescopic rotating shaft, mounting blocks are fixedly provided on both sides of the connecting plate, and the mounting blocks on the left and right sides are respectively rotatably connected to a left rotating rod and a right rotating rod through corresponding rotating shafts, one end of the left rotating rod and the right rotating rod are respectively connected to the two ends of the rotating rod through a left connecting rod and a right connecting rod to form a two-three-link structure, the other ends of the left rotating rod and the right rotating rod are respectively provided with a left clamping block and a right clamping block, the middle part of the rotating rod is rotatably connected to the rotating shaft, and the rotating shaft is fixedly provided on the connecting plate, so that when the rotating rod is toggled to rotate around the rotating shaft, the other ends of the left rotating rod and the right rotating rod are driven to move through the two three-link structures to realize the grabbing action.

[0006] By adopting the above technical scheme, a left rotating rod, a right rotating rod, a left connecting rod, a right connecting rod and a rotating rod form a left and right two-three connecting structure, and the two-three connecting rod structure can be driven together by the rotating rod. By turning the rotating rod, the left rotating rod and the right rotating rod can be synchronously driven to rotate to realize the grasping action. When the bearing to be processed is transported from the loading plate to the position of the transfer mechanism, the bearing to be processed can be grasped and fixed by turning the rotating rod. The transfer mechanism rotates around the telescopic shaft to send the bearing to be processed to the corresponding grinding position of the driving spindle and the grinding wheel. After the bearing to be processed is grasped and fixed, the transfer mechanism can appropriately move away from the plate surface of the working side of the grinding equipment through the telescopic shaft to avoid the friction between the bearing to be processed and the plate surface of the grinding equipment, thereby reducing the wear of the grinding equipment and the bearing to be processed during feeding and improving production efficiency.

[0007] Furthermore, the left clamping block and the right clamping block are both arc-shaped structures and are arranged opposite to each other.

[0008] By adopting the above technical solution, the device can clamp the bearing more stably when transferring the bearing. The left clamping block and the right clamping block can firmly clamp the bearing under the action of the rotating rod to prevent the bearing from rubbing against the device body during the transfer process.

[0009] Furthermore, a left clamping slot is provided inside the left clamping block, and the left clamping slot is arranged in an arc-shaped structure.

[0010] By adopting the above technical solution, the left clamping block can better adapt to the shape of the bearing, thereby providing a more stable and reliable clamping force. The arc structure can ensure that the contact area between the left clamping block and the bearing is larger and more evenly distributed, effectively preventing the bearing from sliding or deflecting during the clamping process.

[0011] Furthermore, a right clamping slot is provided inside the right clamping block, and the right clamping slot is arranged in an arc-shaped structure.

[0012] By adopting the above technical solution, the right clamping block can cooperate with the left clamping block to provide a larger contact area when clamping the bearing, achieve clamping and distribute the clamping force more evenly, and prevent the bearing from shifting during transportation.

[0013] Furthermore, a positioning platform is fixedly connected to the connecting plate by bolts. The positioning platform is in a cylindrical structure. The positioning platform is arranged in an enclosed space formed by the left clamping block and the right clamping block, and the diameter of the positioning platform is consistent with the inner diameter of the bearing to be processed.

[0014] By adopting the above technical solution, the positioning table is fixedly connected to the rear side of one end of the connecting plate by bolts, so that the positioning table can be stably and accurately installed on the connecting plate, thereby ensuring the positioning accuracy of the bearing during the transmission process.

[0015] Furthermore, a bracket is also provided on the connecting plate, the rotating rod is rotatably connected to the bracket via the rotating shaft, and the rotating rod is fixedly connected to the rotating shaft.

[0016] By adopting the above technical solution, the bracket serves as a support member between the rotating rod and the trigger plate, which can provide a stable rotation support point for the rotating shaft, thereby improving the reliability of the equipment.

[0017] Furthermore, the rotating rod is also coaxially connected to a pull plate, and a reset push rod is fixedly connected to the bottom of the loading plate. The end of the reset push rod pointing to the transmission mechanism is in an arc shape, and the end of the reset push rod pointing to the transmission mechanism is arranged on the movable path of the pull plate around the telescopic rotating shaft.

[0018] By adopting the above technical solution, during the process of reloading the telescopic shaft after the bearing processing is completed, the reset push rod can reset the transmission mechanism to achieve the step of clamping the bearing and prepare for the processing of the next bearing, thereby realizing continuous and efficient automated production.

[0019] Furthermore, the loading plate, the transmission mechanism, the driving spindle and the grinding wheel are arranged sequentially along the lateral direction of the working side.

[0020] By adopting the above technical solution, the driving spindle, as the core component of the entire grinding equipment, can provide a stable driving force to rotate the bearing, thereby ensuring the smooth progress of the processing process.

[0021] Furthermore, a guide slide is provided below the driving spindle, and an unlocking push rod is provided below the guide slide.

[0022] By adopting the above technical solution, the guide slide can effectively guide the bearing to move along a predetermined trajectory, reduce the deviation and shaking of the bearing during the collection process after processing, thereby improving the processing quality and efficiency.

[0023] Furthermore, a through hole is provided on the guide slide, and a recovery groove is provided below the guide slide.

[0024] By adopting the above technical solution, it can be ensured that during the processing, debris such as debris and coolant generated by grinding can be smoothly discharged from the through hole, avoiding the accumulation of these debris on the guide slide.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0035] The following describes an embodiment of the utility model based on its overall structure.

A rotating shaft 310 is fixedly connected to one side of the rotating rod 309, and a trigger plate 311 is fixedly connected to one end of the rotating shaft 310. The telescopic function of the telescopic rotating shaft 301 cooperates with the rotational connection of the connecting plate 302, the mounting block 304, and the left rotating rod 305 and the right rotating rod 307 and other components, so that the bearing can be smoothly and accurately delivered to the grinding position, which greatly improves the production efficiency and reduces the complexity of manual operation. During the bearing transfer process, these components can work together to firmly fix the bearing in the grinding position to ensure the accuracy and quality of the grinding. Before starting grinding, they can automatically loosen so that the bearing can be processed smoothly, further improving the degree of automation and ease of operation of the equipment.

[0038] See also Figure 1 and Figure 2 One end of the left rotating rod 305 is fixedly connected to a left clamping block 312, and one end of the right rotating rod 307 is fixedly connected to a right clamping block 313, so that the equipment can clamp the bearing more stably when transferring the bearing. The left clamping block 312 and the right clamping block 313 can firmly clamp the bearing under the action of the rotating rod to prevent the bearing from rubbing against the equipment body during the transfer process. By adjusting the specifications of the left clamping block 312 and the right clamping block 313, bearings of different diameters or widths can be adapted, thereby expanding the processing range of the equipment and improving the flexibility and versatility of the equipment.

[0041] See also Figure 1 and Figure 2 The rear side of one end of the connecting plate 302 is fixedly connected with a positioning platform 303 by bolts. The positioning platform 303 has a cylindrical structure. By fixing the positioning platform 303 by bolts at the rear side of one end of the connecting plate 302, the positioning platform 303 can be stably and accurately installed on the connecting plate 302, thereby ensuring the positioning accuracy of the bearing during the transmission process. The cylindrical structure of the positioning platform 303 can fit tightly with the inner ring of the bearing to provide stable support and positioning for the bearing to prevent it from shaking or shifting during the processing. The cylindrical positioning platform 303 also has good versatility and can adapt to bearings of different inner diameters, thereby expanding the scope of application of the equipment.

[0042] See also Figure 1 and Figure 2 A bracket 4 is arranged between the rotating rod 309 and the pulling plate 311. The bracket 4 and the rotating rod 309 are rotatably connected. The bracket 4 serves as a support member between the rotating rod 309 and the pulling plate 311, and can provide a stable rotation support point for the rotating shaft 310, thereby improving the reliability of the equipment. The design of the bracket 4 also simplifies the assembly and maintenance process of the equipment, and reduces the operation difficulty and maintenance cost.

[0043] See also Figure 1 and Figure 3A reset push rod 5 is fixedly connected to the bottom of the loading plate 2. One end of the reset push rod 5 is in an arc-shaped structure. When the telescopic shaft 301 is loaded again after the bearing processing is completed, the reset push rod 5 can reset the transmission mechanism 3 to achieve the step of clamping the bearing and prepare for the processing of the next bearing, thereby realizing continuous and efficient automated production.

[0044] See also Figure 1 and Figure 3 A driving spindle 6 is provided on one side of the transmission mechanism 3, and a grinding wheel 7 is provided on one side of the driving spindle 6. As the core component of the entire grinding equipment, the driving spindle 6 can provide a stable driving force to rotate the bearing, thereby ensuring the smooth progress of the processing process. Through close cooperation with the driving spindle 6, the grinding wheel 7 can accurately grind the bearing at a high speed, thereby removing burrs and impurities on the bearing surface and improving the accuracy and finish of the bearing.

[0045] See also Figure 1 and Figure 3 A guide slide 8 is provided below the driving spindle 6, and an unlocking push rod 9 is provided below the guide slide 8.

[0046] The implementation principle of the utility model is as follows: first, when the bearing enters from the loading plate 2, the telescopic shaft 301 rotates and retracts, and the positioning platform 303 is inserted into the bearing. At the same time, the pull plate 311 contacts the reset push rod 5 and is pushed by the reset push rod 5 during the rotation and retraction process, driving the rotating shaft 310 to rotate. The rotation of the rotating shaft 310 drives the rotating rod 309 to rotate, and then pushes the left connecting rod 306 and the right connecting rod 308, driving the left connecting rod 306 and the right connecting rod 308 to rotate around the axis, rotating the left clamping block 312 and the right clamping block 313 from the horizontal position, using the left clamping groove 314 and the right clamping groove 315 to clamp the bearing, and then rotating the telescopic shaft 311. The rotating shaft 301 sends the bearing into the interior of the driving main shaft 6, and at the same time, the pull plate 311 is pushed by the unlocking push rod 9, driving the rotating shaft 310 to rotate. The rotation of the rotating shaft 310 drives the rotating rod 309 to rotate, and then pulls the left connecting rod 306 and the right connecting rod 308, driving the left connecting rod 306 and the right connecting rod 308 to rotate around the axis, and rotating the left clamping block 312 and the right clamping block 313 from the clamping position to the loose position, so that the bearing can rotate under the drive of the driving main shaft 6 and be polished by the grinding wheel 7. Then the telescopic rotating shaft 301 moves outward, so that the polished bearing falls into the guide slide 8 and is collected along the guide slide 8.
