Description

Technical Field

[0001] This utility model relates to the technical field of steel ball processing equipment, specifically a precision grinding plate for steel balls. Background Technology

[0002] As the final and crucial step in steel ball processing, fine grinding plays a decisive role in the precision and surface quality of the steel balls. During the fine grinding process, a fine grinding plate with concentric grooves grinds the semi-finished steel balls into high-precision products with the help of abrasives in a specific cyclic manner. The quality of the fine grinding plate is the foundation for obtaining high-precision steel balls, while abrasives and processes are important guarantee conditions.

[0003] When two grinding plates are installed on a grinding machine, they are usually fixed directly to the grinding equipment. The spacing between the two grinding plates cannot be adjusted according to the size of the steel ball. This means that when grinding steel balls of different sizes, the grinding plates need to be disassembled and their positions adjusted, which greatly reduces work efficiency. In addition, the traditional fixing method makes it cumbersome and troublesome to replace or repair the grinding plates when problems occur, resulting in time-consuming and labor-intensive repairs or replacements. Utility Model Content

[0004] To address the problems of inconvenient spacing adjustment and cumbersome disassembly, maintenance, and replacement processes associated with precision grinding plates, this utility model aims to provide a precision grinding plate for steel balls.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a precision grinding plate for steel balls, comprising a base plate, two symmetrically distributed fixing plates fixedly installed at the top of the base plate, two sets of mounting plates fixedly installed at the middle of both sides of the two fixing plates, a double-ended screw rotatably installed at the middle of the middle of the two sets of mounting plates, two symmetrically distributed fixing blocks threadedly installed on the outer sides of the two double-ended screws, two sets of mutually cooperating fixing clamps provided at the middle of the opposite side of the fixing blocks, the two ends of the two sets of fixing clamps slidably locked at the middle of one side of the fixing blocks, a rolling groove opened in the middle of the middle of the two sets of fixing clamps, a precision grinding plate body slidably locked in the middle of the rolling groove, a worm gear fixedly installed through one side of the two double-ended screws through the mounting plates, a worm rotatably installed on the upper side of the two mounting plates, and the two worms meshing with the worm gears.

[0006] Preferably, each of the four fixing blocks has four evenly distributed first fixing holes on one side, and a bolt is slidably inserted through the middle of each of the four first fixing holes. Nuts that cooperate with each other are threaded onto the lower part of each bolt.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This application can adjust the distance between two relatively rotating precision grinding plates by rotating a double-headed screw. This allows operators to easily control the distance between the precision grinding plates when processing and grinding steel balls of different sizes, without the need for complicated disassembly or installation procedures, thus greatly saving adjustment time and improving work efficiency.

[0009] 2. This application facilitates the fixing and disassembly of the grinding plate by fixing and disassembling the fixing clamp, which makes it easier to repair and replace the grinding plate body. At the same time, the rolling of the balls carries out the lubricant stored in the cavity to lubricate the rolling groove, reducing the frictional loss of the grinding plate body during rotation and extending its service life.

[0019] 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.

[0020] Example: Figure 1-7 As shown, this utility model provides a precision grinding plate for steel balls, including a base plate 1. Two symmetrically distributed fixing plates 2 are fixedly installed at the top of the base plate 1. Two sets of mounting plates 24 are fixedly installed at the middle of both sides of the two fixing plates 2. Double-headed screws 21 are rotatably installed at the middle of the middle of the two sets of mounting plates 24. Two symmetrically distributed fixing blocks 22 are threadedly installed on the outer side of the two double-headed screws 21. Two sets of mutually cooperating fixing clips 3 are provided at the middle of the opposite side of the fixing blocks 22. The two ends of the two sets of fixing clips 3 are slidably locked at the middle of one side of the fixing block 22. Rolling grooves 39 are opened in the middle of the two sets of fixing clips 3. The precision grinding plate body 31 is slidably locked in the middle of the rolling grooves 39. Worm gears 25 are fixedly installed through one side of the two double-headed screws 21 and through the mounting plates 24. Worms 26 are rotatably installed on the upper side of the two mounting plates 24. The two worm gears 26 mesh with the worm gears 25.

[0021] Each of the four fixing blocks 22 has four evenly distributed first fixing holes 321 on one side. Each of the four first fixing holes 321 has a bolt 32 that slides through the middle. Each of the bolts 32 has a nut 322 threaded on its lower part for mutual use.

[0022] Each of the four fixing clamps 3 has a cavity 34 in the middle of one side, and a pipe 35 is fixedly installed in the middle of one side of each of the four fixing clamps 3. The pipe 35 communicates with the cavity 34. Each of the fixing clamps 3 has a plurality of evenly distributed slots 37 in one side. Each of the slots 37 has a ball bearing 38 slidably mounted on one side. Each ball bearing 38 is in contact with one side of the grinding plate body 31. By setting the ball bearing 38 and the cavity 34, and filling the cavity 34 with lubricating fluid, when the grinding plate body 31 rotates, it will drive the ball bearing 38 to rotate, thereby carrying out the lubricating fluid inside the cavity 34 and letting it enter the rolling groove 39, thereby lubricating the grinding plate body 31 and reducing friction damage.

[0023] Each of the multiple pipes 35 has a sealing cap 36 threaded on one side. By setting the sealing cap 36, after the lubricant is loaded into the cavity 34 through the pipe 35, the sealing cap 36 can be threaded on one side of the pipe 35.

[0024] Each end of the multiple fixing clips 3 has two symmetrically distributed second fixing holes 33. The middle of the multiple bolts 32 slides through the second fixing holes 33. By setting the second fixing holes 33, the bolts 32 can be passed through the second fixing holes 33 to fix the fixing clips 3.

[0025] Grinding grooves 311 are provided on opposite sides of the precision grinding plate body 31. By providing grinding grooves 311, when the two precision grinding plate bodies 31 rotate relative to each other, steel balls enter the grinding grooves 311 for grinding.

[0026] Each of the two worm gears 26 has a handle 261 fixedly installed at one end of the mounting plate 24. Each of the two fixing plates 2 has a groove 23 in the middle. The four fixing blocks 22 are slidably locked in the middle of the groove 23. By setting the handle 261, rotating the handle 261 can drive the worm gear 26 to rotate.

[0027] The base plate 1 has two sets of evenly distributed mounting holes 11 on both sides. By setting the mounting holes 11 and cooperating with the fasteners, the device can be fixedly installed on the grinding machine.

[0028] Working principle: In actual use, the grinding plate body 31 is placed between two fixing clamps 3, so that the outer side of the grinding plate body 31 is engaged inside the rolling groove 39. The first fixing hole 321 and the second fixing hole 33 are aligned with each other. After the bolt 32 passes through the first fixing hole 321 and the second fixing hole 33, the nut 322 is installed at the lower part of the bolt 32. Through the cooperation of the bolt 32 and the nut 322, the fixing clamps 3 are limited and fixed, thereby clamping and fixing the grinding plate body 31. The side-sliding clip is located in the middle of the rolling groove 39, which ensures that the grinding plate body 31 can rotate between the two fixed clamps 3, thus enabling normal operation. After the grinding plate body 31 is connected to the drive device on the grinding machine, when the grinding plate body 31 is rotated to grind the steel ball, the outer side of the grinding plate body 31 contacts the ball 38, causing the ball 38 to rotate. The rotation of the ball 38 carries out the lubricant stored in the cavity 34, thereby lubricating the rolling groove 39 and reducing the frictional wear of the grinding plate body 31.

[0029] Rotating the handle 261 can drive the worm gear 26 to rotate, which in turn drives the meshing worm wheel 25 to rotate, thereby driving the double-headed screw 21 to rotate, which in turn drives the two fixed blocks 22 to rotate, thus adjusting the distance between the two precision grinding plate bodies 31, so that steel balls of different sizes can enter the grinding groove 311 for grinding.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
