[0002] Floating oil seals are a type of dynamic seal that have superior sealing performance in harsh working environments such as those with coal dust, silt, water, and gas. They are compact mechanical seals mainly used in low-speed, heavy-load applications. They have advantages such as wear resistance, automatic compensation after end face wear, reliable operation, and simple structure.

[0003] In related technologies, grinding is required during the production of floating oil seals. Application No. CN212824447 U discloses an automated grinding equipment for floating oil seals. This device, equipped with a horizontal plate, lead screw, slide rail, slider, geared motor, drive wheel, driven wheel, and transmission belt, can move the drive motor and grinding disc up and down to achieve better grinding results and further ensure grinding quality. However, during use, the position of the grinding disc cannot be adjusted according to needs, resulting in insufficient grinding of floating oil seals in the corners of the grinding table. This requires operators to stop the device and manually adjust it, greatly reducing the practicality and efficiency of the device.

[0004] Therefore, it is necessary to provide a new type of automatic grinding machine for floating oil seals to solve the above-mentioned technical problems. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the novel automatic grinding machine for floating oil seals provided by this utility model; Figure 2 for Figure 1 The diagram shows a side sectional view of the lifting assembly. Figure 3 for Figure 1A schematic diagram of the structure of the protective cover shown in the side sectional view; Figure 4 for Figure 1 The diagram shows a side view of the worktable. A novel automatic grinding machine for floating oil seals includes: a worktable 10, a lifting assembly 20 on the top of the worktable 10, an adjusting assembly 30 inside the lifting assembly 20, and a mounting assembly 40 on the top of the worktable 10 and located at the bottom of the adjusting assembly 30;

[0024] The lifting assembly 20 includes a lifting frame 21 disposed on the top of the workbench 10, a lifting plate 22 slidably disposed on the inner side of the lifting frame 21, and two hydraulic rods 23 fixedly installed on the top of the lifting frame 21 to drive the lifting plate 22 to slide up and down.

[0025] The adjustment assembly 30 includes two adjustment frames 31 disposed inside the lifting plate 22. Two lead screws 32 are rotatably disposed inside the adjustment frame 31. Adjustment blocks 33 are threaded on the surface of the lead screws 32. A sliding groove is opened inside the lead screws 32 so that the adjustment blocks 33 can slide left and right. A first bevel gear 34 is rotatably disposed on an adjacent side of the two lead screws 32.

A first motor 36 that drives the second bevel gear 35 to rotate is fixedly installed on the top of the lifting plate 22.

[0026] According to the usage requirements, the first motor 36 starts working, driving the second bevel gear 35 to rotate. In conjunction with the meshing of the first bevel gear 34, it drives the two lead screws 32 to rotate, causing the two adjusting blocks 33 to slide towards the center, adjusting the distance between the two U-shaped plates 37 to a suitable distance. The hydraulic rod 23 starts working, driving the lifting plate 22 to move downward, so that the grinding disc 38 moves to a suitable height. Through the action of the second motor 39, the floating oil seal on the grinding table 50 can be ground in all directions, avoiding some areas not being effectively ground, thereby improving the grinding quality.

[0027] The mounting assembly 40 includes two protective covers 41 disposed on the top of the workbench 10 and located at the bottom of the adjustment frame 31. Two mounting blocks 42 are fixedly installed on the bottom of each protective cover 41. Two mounting holes 43 are opened on the inner side of each mounting block 42. Fixing blocks 44 are fixedly installed on the left and right sides of the protective cover 41. Threaded rods 45 are rotatably provided on the bottom of each fixing block 44. Positioning blocks 46 are threaded on the surface of each threaded rod 45.

[0028] During the use of the device, the operator installs the mounting block 42 inside the mounting groove and fits the mounting hole 43 onto the surface of the mounting rod, so that the two protective covers 41 fit together. By manually turning the knob, the threaded rod 45 is rotated, which in turn moves the positioning block 46 downward and inserts it into the inner side of the positioning groove 60 to position the protective cover 41. This makes it easy for the operator to disassemble the protective cover 41 for maintenance and replacement.

[0029] Lifting slots 24 are provided on the inner side of the lifting frame 21, and lifting blocks that slide up and down along the inner side of the lifting slots 24 are fixedly installed on both the left and right sides of the lifting plate 22.

[0030] One end of each of the first bevel gears 34 is fixedly connected to one end of the adjacent lead screw 32, and the surface of each of the second bevel gears 35 is engaged with the two first bevel gears 34.

[0031] Each adjusting block 33 has a U-shaped plate 37 fixedly installed at its bottom. Each U-shaped plate 37 has a grinding disc 38 rotatably mounted on its inner side. Each U-shaped plate 37 has a second motor 39 fixedly installed on its surface to drive the grinding disc 38 to rotate.

[0032] The top of the positioning block 46 is slidably provided with sliding rods 47 near the four corners. The top of each sliding rod 47 is fixedly connected to the bottom of the fixing block 44. The top of the fixing block 44 is rotatably provided with a knob to drive the threaded rod 45 to rotate.

The front and rear sides of the workbench 10 are provided with mounting grooves that are compatible with the mounting blocks 42. Mounting rods that are compatible with the mounting holes 43 are fixedly installed inside the mounting grooves. Positioning grooves 60 that are compatible with the positioning blocks 46 are provided on the top of the workbench 10 and on the left and right sides of the grinding table 50.

[0034] The working principle of the novel automatic grinding machine for floating oil seals provided by this utility model is as follows:

[0035] Step 1: During the use of the device, the operator installs the mounting block 42 inside the mounting groove and fits the mounting hole 43 onto the surface of the mounting rod, so that the two protective covers 41 fit together. Then, by manually turning the knob, the threaded rod 45 is rotated, which in turn moves the positioning block 46 downward and inserts it into the inner side of the positioning groove 60 to position the protective cover 41. This makes it easy for the operator to disassemble the protective cover 41 for maintenance and replacement.

[0036] Step 2: According to the usage requirements, the first motor 36 starts working, driving the second bevel gear 35 to rotate. In conjunction with the meshing of the first bevel gear 34, it drives the two lead screws 32 to rotate, causing the two adjusting blocks 33 to slide towards the center, adjusting the distance between the two U-shaped plates 37 to a suitable distance. The hydraulic rod 23 starts working, driving the lifting plate 22 to move downward, so that the grinding disc 38 moves to a suitable height. Through the action of the second motor 39, the floating oil seal on the grinding table 50 can be ground in all directions, avoiding some areas not being effectively ground, thereby improving the grinding quality.

[0037] Compared with related technologies, the novel automatic grinding machine for floating oil seals provided by this utility model has the following advantages:

[0038] With the various components of the device working together, the first motor 36 starts working, driving the second bevel gear 35 to rotate. In conjunction with the meshing of the first bevel gear 34, it drives the two lead screws 32 to rotate, causing the two adjusting blocks 33 to slide towards the center, adjusting the distance between the two U-shaped plates 37 to a suitable distance. This allows for all-round grinding of the floating oil seal on the grinding table 50, preventing some areas from not being effectively ground, thus improving the grinding quality. In conjunction with the function of the mounting component 40, it facilitates the disassembly of the protective cover 41 by the staff, making maintenance and replacement convenient.
