Description

Technical Field

[0001] This utility model relates to the field of oilstone clamp technology, and in particular to an oilstone clamp that is easy to replace. Background Technology

[0002] An oilstone is an oil-rich rock with a fine and tough texture, used as an abrasive. To ensure the polishing quality of the workpiece surface, the oilstone's position needs to be stable; therefore, it is commonly held in a clamp during processing. Over time, the oilstone wears down, and once it reaches its wear limit and can no longer be used, it needs to be replaced. However, existing clamps are not convenient for quickly disassembling the oilstone, requiring workers to spend a significant amount of time disassembling it, which reduces processing efficiency. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a conveniently replaceable oilstone clamp.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An easy-to-replace oilstone clamp includes a clamp sleeve and a fixing plate. The bottom of the clamp sleeve has a through-hole. The fixing plate is installed at the bottom through-hole of the clamp sleeve by a positioning bracket arranged around its outer circumference. A stud is rotatably installed at the center of the top surface of the fixing plate, and a mounting plate is threaded onto the stud.

[0006] In a preferred embodiment, the mounting plate has a through hole at its center for the stud to pass through, and a threaded sleeve adapted to the thread of the stud is disposed in the through hole. In another preferred embodiment, the stud extends upward from the top surface of the clamp sleeve, and a rotating block is disposed at the top of the stud, with an anti-slip rubber sleeve covering the outside of the rotating block.

[0007] The bottom surface of the fixed plate is slidably connected to several sliding platforms, which are circumferentially distributed and each has a clamping block at its bottom. The oilstone blocks are clamped by the circumferentially distributed clamping blocks.

[0008] The bottom surface of the mounting plate is provided with circumferentially distributed support legs, and each support leg is equipped with a connecting rod at its bottom. The lower end of each connecting rod is rotatably connected to the top of the corresponding slide below.

[0009] In a preferred embodiment, the bottom surface of the mounting plate is provided with circumferentially distributed guide rails, and the guide rails are distributed one-to-one with the connecting rods above. The bottom surface of the mounting plate is provided with circumferentially distributed legs, and the bottom of each leg is respectively equipped with a connecting rod, the lower end of each connecting rod being rotatably connected to the top of the corresponding slide below.

[0010] In a preferred embodiment, the upper surface of the slide table is provided with a slider, and the slider is provided with a dovetail groove that is adapted to slide with the guide rail.

[0011] In a preferred embodiment, the outer ends of the slide table are bent upwards to form vertical arms, and the slide table and the vertical arms at its outer ends form an integral structure. The lower ends of the connecting rods are rotatably connected to the corresponding vertical arms.

[0012] In a preferred embodiment, the slides slide toward the center of the fixed plate, and the positions of the slides and the positioning brackets are offset relative to each other.

[0013] The beneficial effects of this utility model are:

[0014] The oilstone clamp proposed in this solution solves the problem of inconvenient oilstone replacement, which affects processing efficiency. The spiral clamping method of the oilstone blocks can ensure that they are fixed in position during fine grinding. At the same time, the four clamping blocks used to lock the oilstone blocks can be quickly separated, making it convenient for workers to quickly remove worn oilstone blocks and put in new ones. The operation is convenient and can improve the efficiency of fine grinding. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In this embodiment, refer to Figure 1-4An easy-to-replace oilstone clamp includes a clamp sleeve 1 and a fixing plate 3. The bottom of the clamp sleeve 1 has a through-hole 15. The fixing plate 3 is installed at the bottom through-hole 15 of the clamp sleeve 1 by a positioning bracket 2 arranged around the outer circumference.

[0022] A stud 4 is rotatably mounted at the center of the top surface of the fixed plate 3, and a mounting plate 5 is threaded onto the stud 4. Several sliding tables 10 are slidably connected to the bottom surface of the fixed plate 3. (See attached) Figure 3 As shown, the bottom surface of the mounting plate 5 is provided with circumferentially distributed guide rails 8, and the upper surface of the slide table 10 is provided with a slider 9. The slider 9 is provided with a dovetail groove 14 that is adapted to slide along the guide rails 8. The slider 9 can slide linearly along the guide rails 8.

[0023] The slide table 10 is circumferentially distributed, and clamping blocks 11 are respectively provided at the bottom of the slide table 10. The oilstone block 12 in the middle is clamped by the circumferentially distributed clamping blocks 11. See attached. Figure 2 Or attached Figure 3 As shown, the slides 10 slide towards the center of the fixed plate 3, and the positions of the slides 10 and the positioning brackets 2 are relatively offset. The sliding process of the slides 10 does not affect the position of the positioning brackets 2.

[0024] The bottom surface of the mounting plate 5 is provided with circumferentially distributed support legs 6. Connecting rods 7 are respectively installed at the bottom of the support legs 6, and guide rails 8 are distributed one-to-one with the connecting rods 7 above. The lower end of each connecting rod 7 is rotatably connected to the top of the corresponding slide table 10 below. Here, in conjunction with the attached... Figure 4 It can be seen that the outer ends of the slide table 10 are bent upwards to form vertical arms. The slide table 10 and the vertical arms at its outer ends form an integral structure. The lower ends of the connecting rods 7 are rotatably connected to the corresponding vertical arms.

[0025] A through hole is formed in the center of the mounting plate 5 for the stud 4 to pass through, and a threaded sleeve adapted to the thread of the stud 4 is installed in the through hole. The stud 4 extends upward from the top surface of the clamp sleeve 1, and a rotating block 13 is provided at the top of the stud 4. The rotating block 13 is covered with an anti-slip rubber sleeve. By rotating the stud 4, the mounting plate 5 moves along the length of the stud 4, thereby achieving the purpose of raising and lowering the mounting plate 5. The threaded drive mechanism has a self-locking function, which can maintain the position of the mounting plate 5. When the oilstone block 12 is clamped, it can ensure that the oilstone block 12 has a high clamping force and prevent the oilstone block 12 from loosening and falling off.

[0026] A groove is reserved in the clamp sleeve 1 for the vertical lifting and lowering of the mounting plate 5. When the stud 4 is rotated forward and the mounting plate 5 is raised, the connecting rod 7 can be pulled. Since the slide 10 on the top of the clamping block 11 slides along the guide slide 8, each slide 10 will move towards the center of the fixed plate 3 at the same time and thereby clamp the oilstone block 12. When the oilstone block 12 is worn out and needs to be replaced, the operator only needs to rotate the stud 4 in the opposite direction and control the mounting plate 5 to descend. At this time, each slide 10 will move away from the center of the fixed plate 3 at the same time and remove the clamping of the original oilstone block 12. The oilstone block 12 will automatically detach, making it easy to put in a new oilstone block 12. Then, the stud 4 is rotated forward again to control the clamping block 11 to clamp the new oilstone block 12. The operation is more convenient.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
