Technical Field
[0001] This utility model relates to the technical field of eccentric bushing inner wall grinding equipment, specifically an eccentric bushing inner wall grinding equipment. Background Technology
[0002] Eccentric bushings are core components of crushers. However, the internal structure of eccentric bushings is often irregular during processing, which can easily lead to burrs and affect performance. Therefore, the inner wall of the eccentric bushing needs to be processed and polished. However, traditional polishing devices do not have a cooling structure, which can cause workers to get burned when handling the polished eccentric bushing. Furthermore, since the eccentric bushing needs to be limited during polishing to prevent displacement, an eccentric bushing inner wall polishing device with a cooling and limiting structure has been designed.
[0003] A processing device for an eccentric bushing, authorized by announcement number CN219189433U, includes a clamping shaft and a mounting plate located at the upper end of the clamping shaft. The clamping mechanism includes a clamping component one and a clamping component two. The clamping component one includes a mounting base one mounted to the mounting plate and a fixing plate one rotatably connected to the upper end of the mounting base one, with a pressure plate one disposed on the fixing plate one. The clamping component two includes a mounting base two mounted to the mounting plate and a fixing plate two rotatably connected to the upper end of the mounting base two, with a pressure plate two disposed on the fixing plate two. An inclined pad is slidably inserted into the lower end of the fixing plate two toward the center of the mounting plate. This utility model, by using different components on the same fixture, can achieve two different clamping states for the eccentric bushing, facilitating the processing of the eccentric through hole in the middle of the eccentric bushing and the inclined shaft at the upper end, avoiding the problem of changing different fixtures and different processing equipment.
[0004] Based on existing solutions and actual production and processing, current eccentric bushing inner wall grinding equipment still has some problems: it is not convenient to clamp and limit the eccentric bushing, it is not convenient to adjust the clamping distance according to the height of the eccentric bushing, and it is not convenient to perform cooling treatment on the inner wall of the eccentric bushing during grinding. Therefore, this utility model provides an eccentric bushing inner wall grinding equipment to solve the above-mentioned problems. Utility Model Content

[0026] 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.
[0027] Please see Figure 1-5 This utility model provides a technical solution: an eccentric bushing inner wall grinding device, including a worktable 1, a protective shell 2, a pipe 3, a mounting plate 4, a bidirectional threaded screw 5, a motor 6, a first clamping block 7, a second clamping block 8, a fixing block 9, a connecting toothed ring 10, a threaded rod 11, a mounting shell 12, a fixing rod 13, a spring 14, a clamping plate 15, a support frame 16, a telescopic rod 17, a support plate 18, a grinding device body 19, a bottle 20, a folded corrugated pipe 21, and a nozzle 22. Specific Implementation Example 1;
[0029] Existing eccentric bushing internal wall grinding equipment lacks clamping and cooling mechanisms. To address this issue, this embodiment includes, for example, the following... Figure 1 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 As shown, when it is necessary to adjust the internal clamping distance according to the inner wall diameter of the eccentric bushing, the eccentric bushing is placed on the upper ends of the first clamping block 7 and the second clamping block 8 on the left and right sides. At this time, the protrusions of the first clamping block 7 and the second clamping block 8 are located inside the eccentric bushing. At this time, the motor 6 is started to drive the bidirectional threaded screw 5 to rotate. When the bidirectional threaded screw 5 rotates, it drives the first clamping block 7 and the second clamping block 8 to move to the left and right sides respectively until they are in contact with the inner wall of the eccentric bushing. Then the rotation of the bidirectional threaded screw 5 can be stopped, thereby achieving the clamping and limiting of the inner wall of the eccentric bushing.
[0030] When clamping eccentric bushings of different heights, as shown in the attached... Figure 1 and attached Figure 5 As shown, after the eccentric bushing is limited by the clamping device, in order to prevent the eccentric bushing from loosening during high-level grinding and affecting the grinding efficiency, the connecting toothed rings 10 are provided on the left and right sides of the fixing block 9 respectively. The connecting toothed rings 10 drive the threaded rod 11 to move towards the middle of the mounting plate 4. The threaded rod 11 then drives the mounting shell 12 to fit against the outer wall of the eccentric bushing. Before fitting, the clamping plate 15 needs to be manually held to drive the fixing rod 13 to squeeze the spring 14 to achieve height adjustment, so that the lower end of the clamping plate 15 fits against the upper end of the eccentric bushing. This achieves stable positioning of the eccentric bushing at different heights on the clamping device.
[0031] When grinding and cooling the eccentric bushing, as shown in the attached... Figure 1 As shown, when the telescopic rod 17 is activated, the support plate 18 moves downward. The support plate 18 then drives the grinding device body 19 to be inserted into the eccentric bushing. At this time, the grinding device body 19 is activated to grind the inner wall of the eccentric bushing. When the grinding device body 19 is activated, the nozzle 22 is sensed by the sensor of the grinding device body 19, so that the liquid inside the bottle 20 is guided through the folded corrugated pipe 21 and output through the nozzle 22, and finally sprayed on the eccentric bushing to achieve cooling treatment. Some water will flow into the interior of the mounting plate 4. The channel set inside the mounting plate 4 outputs it to the protective shell 2, and finally discharges it outward through the pipe 3.
