Description

Technical Field

[0001] The utility model relates to the technical field of limit ring grinding, in particular to a tool for grinding the upper limit ring of an automobile engine. Background Art

[0002] When the brake clearance is within the set value, the limit friction ring does not move during braking, and the wheel cylinder piston only moves in the axial clearance with the limit ring to drive the brake to act. If the brake clearance is greater than the set value, the wheel cylinder piston first moves in the limit ring clearance during braking. When the hydraulic pressure of the braking system rises to a certain value, the piston is pushed by the hydraulic force and drives the limit friction ring to move together until the brake shoe is in close contact with the drum (disc) to produce a braking effect; when the brake is released, the piston resets to the set position due to the restriction of the limit ring, that is, the brake shoe can only be reset to the position of the set clearance.

[0003] However, when using the limit ring, the impurities in the ring need to be cleaned out before using the limit ring, otherwise it is easy to cause the support rod in the limit ring and the limit ring to be damaged by friction. The existing tools for grinding the limit ring generally require manual grinding, which can easily scratch the worker's hands when the machine is running.

[0004] Therefore, in order to solve the above problems, a grinding tool for the upper limit ring of an automobile engine is proposed. Utility Model Content

[0022] A tool for grinding an upper limit ring of an automobile engine comprises: a table body 1, an internal grinding structure 2, a sliding clamp 3, an insertion structure 4 and an external grinding structure 5. One side of the upper end of the table body 1 is connected to the internal grinding structure 2 by bolts, the lower end of the sliding clamp 3 at the front end of the internal grinding structure 2 is connected to a slide groove 103 at the upper end of the table body 1 by a slider, the insertion structure 4 at the rear end of the sliding clamp 3 is connected to the slide groove 103 by a lower end slider, and the front end of the insertion structure 4 is installed with bolts to the external grinding structure 5.

[0023] Furthermore, the four corners of the lower end of the table body 101 in the table body 1 are connected to the table legs 102 by bolts, and there are hollow slide grooves 103 on both sides of the middle of the upper end of the table body 101. The slide grooves 103 are used to make the first vertical rod 301 and the second vertical rod 401 slide inside the slide grooves 103.

[0024] Furthermore, brackets 202 are welded on both sides of the middle of the support shell 201 in the internal grinding structure 2, and the upper end of the bracket 202 is connected to the first motor 203 with bolts. The front end of the first motor 203 passes through the interior of the support shell 201, and the front end of the first motor 203 is connected to the inner grinding rod 204 with bolts. The front end of the first motor 203 is connected to the grinding rod 204 with bolts to enable the grinding rod 204 to use the rotational force of the first motor 203 to grind the inside of the limit ring so that impurities inside the limit ring are cleaned up.

[0025] Furthermore, a rotating rod 302 is inserted into the circular hollow portion at the upper end of the first vertical rod 301 in the sliding clamp 3, the rear end of the rotating rod 302 is connected to the rotating switch 303 with bolts, the front end of the rotating rod 302 passes through the gasket groove 304, the gasket groove 304 is circular and hollow inside, the rear end of the rotating rod 302 is connected to the rotating switch 303 with bolts so that the rotating rod 302 can also rotate when the rotating switch 303 is rotated, and the front end of the rotating rod 302 is inserted into the gasket groove 304 so that the clamp shell 305 maintains a certain distance from the first vertical rod 301.

[0026] Furthermore, the bottom of the clamp shell 305 is welded to the front end of the pad groove 304, and the circular hollow at the center of the rear end of the clamp shell 305 passes through the rotating shaft 306. The outer periphery of the rotating shaft 306 is connected to the inside of the rope groove 307 with bolts. The rope 308 is wound around the rope groove 307, and the rope 308 is drilled out from the rope holes 309 on the four sides of the outside of the rope groove 307.

The front end of the second motor 503 is bolted to the outer-ring grinding structure 504 so that the second motor 503 can rotate the grinding structure 504 to grind the outside of the limit ring when it is running.

[0029] Working principle: When in use, first place the limit ring inside the clamp 311, turn the rotation switch 303 to rotate the rotation shaft 306 at the front end of the rotating rod 302, so that the rope 308 inside the rope groove 307 is tightened during rotation, and the clamp 311 at the front end of the rope 308 is contracted to clamp the limit ring, and then push the first vertical rod 301 to insert the circular hollow inside the limit ring into the outer periphery of the inner grinding rod 204, and turn on the first motor 203 to rotate the inner grinding rod 204 for grinding. After grinding the inside of the limit ring, insert the hollow part of the limit ring into the insertion head 402, slide the limit ring into the insertion head 402 until it can no longer slide, push the second vertical rod 401 to insert the outside of the limit ring into the grinding structure 504 outside the ring, turn on the second motor 503 to make the grinding structure 504 outside the ring rotate to rub the outside of the limit ring, and the friction structure 403 outside the insertion head 402 can prevent the limit ring from falling off suddenly when being ground from the outside.
