Description

Technical Field

[0001] This utility model belongs to the field of grinding and polishing of workpieces using grinding heads on CNC machine tools, and specifically relates to a flexible lateral fixing and clamping mechanism for clamping grinding stones. Background Technology

[0002] In machine tool processing of silicon nitride rings, ceramics, and glass, grinding is used. The grinding head mounted on the spindle requires frequent, phased, and area-specific finishing of the bottom and side edges of the grinding wheel after a period of processing to ensure dimensional consistency. The finishing typically uses an oilstone, the size of which varies depending on the specific application. For example, a 200mm long, 60mm wide, and 24mm thick stone might be chosen. However, due to cutting errors, the actual dimensions in each direction may deviate from the theoretical values ​​by 1-2mm. For ease of use, the oilstone is often fixed in place on-site using common clamping plates, right-angle blocks, T-nuts, and countersunk screws. The clamping plate directly presses down on the center of the oilstone's upper surface, limiting finishing to the sides of the grinding wheel. To ensure absolute pressure, the center of the oilstone is covered by the clamping plate, which must be avoided during use until the oilstone is worn down to 3mm and unusable. This method of use results in the underutilization of the central portion. Furthermore, when installing oilstones, they are often placed in positions that do not interfere with the machine tool's processing. When replacing oilstones, the position of the oilstone relative to the machine tool cannot be guaranteed to be within a small error range compared to the previous one. Therefore, the installation position is not fixed each time. This requires re-determining the coordinate position of the oilstone after each replacement so that the grinding head can continue grinding. This increases some of the auxiliary work inside the machine, occupies the machine tool's green light time, and thus affects the time for the machine tool to process parts, affecting the efficiency of parts delivery. Utility Model Content

[0003] To address the aforementioned practical problems, this utility model proposes a flexible lateral fixing clamping mechanism for mounting whetstones. This mechanism allows for quick installation of whetstones with minimal positional deviation each time, while also solving the problem of repeated waste of whetstones.

[0004] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0005] This utility model provides a flexible lateral fixing clamping mechanism for clamping a whetstone, including: a mounting base, a lateral pressing mechanism, a lateral moving mechanism, and a mounting mechanism. The mounting base is disposed on the machine tool worktable, and the mounting mechanism is disposed on both sides of the long side of the mounting base to fix the mounting base to the machine tool worktable. The lateral pressing mechanism is disposed at the lowest step on the upper surface of the mounting base, and the lateral moving mechanism is disposed on the vertical side of the mounting base. The moving state of the lateral moving mechanism is determined by a square groove guide.

[0006] Furthermore, the lateral clamping mechanism includes a lateral clamping plate, an M10-L25 countersunk screw, and an annular sealing ring. After the M10-L25 countersunk screw is installed on the lateral clamping plate, an annular sealing ring is installed on the threaded end of the M10-L25 countersunk screw. The annular sealing ring needs to contact the lower end face of the lateral clamping plate.

[0007] Furthermore, the number of lateral clamping mechanisms can be adjusted according to the shape of the oilstone, and they can be evenly distributed on one side of the oilstone.

[0008] Furthermore, the lateral movement mechanism includes an M10-L16 countersunk screw, a lateral movement block, and a compression spring.

[0009] Furthermore, the compression spring is positioned between the mounting base and the lateral moving block. The M10-L16 countersunk screw contacts the lateral moving block against the outer end face of the compression spring. Tightening the M10-L16 countersunk screw clockwise causes the lateral moving block to move inward under the guidance of the lateral square groove of the mounting base, shortening the length of the compression spring. Tightening the M10-L16 countersunk screw counterclockwise causes the lateral moving block to move outward under the action of the compression spring, guided by the lateral square groove of the mounting base, lengthening the compression spring. The compression spring remains in a compressed state.

[0010] Furthermore, the lateral movement mechanism needs to be adjusted according to the position and number of the lateral clamping mechanism, and the scale lines on the upper surface of the multiple lateral movement blocks should be kept in the same position.

[0011] Furthermore, the mounting mechanism includes M14-L30 countersunk screws and T-nuts, with different specifications selected according to different machine tool tables.

[0012] Furthermore, fix all the above mechanisms and parts in a position that will not interfere with the machine tool processing, place the oilstone on the reference surface of the mounting base, tighten the M10-L25 countersunk screws of the lateral clamping mechanism clockwise, and the lateral clamping plate will clamp the oilstone. Loosen the M10-L25 countersunk screws of the lateral clamping mechanism counterclockwise, and the lateral clamping plate will release the oilstone.

[0013] Compared with existing technologies, the beneficial effects of this utility model patent are as follows: A flexible lateral clamping mechanism for fixing and clamping the whetstone on the machine tool worktable does not interfere with the central parts of the worktable and can be installed in the same position without needing to change the installation location. When using the whetstone for the first time, the installation position relative to the machine tool needs to be determined. When replacing the whetstone at the end of its service life and reinstalling it, this clamping mechanism has precise references in the X / Y / Z directions. The whetstone is tightly attached to these references in each direction, thus determining the installation position relative to the machine tool, with a deviation from the previous installation position within 0.1mm. The clamping position of the whetstone has changed from the original center to the side, and it is tightly clamped within 2mm of the bottom of the whetstone. All remaining whetstone parts can be fully utilized, eliminating waste. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the embodiments described herein are merely illustrative and are not intended to limit the scope of protection of this utility model.

[0020] The application principle of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 The image shown is a top view of the flexible lateral clamping mechanism for holding the whetstone installed at a specific position on the worktable. Figure 2 It is a component of a flexible lateral fixing clamping mechanism for clamping whetstones. Figure 3 , Figure 4The diagram shows the components of each mechanism. The flexible lateral clamping mechanism for clamping the whetstone includes: a mounting base 3, a measuring and moving mechanism 4, a lateral clamping mechanism 5, and a mounting mechanism 6. The mounting base 3 is mounted on the machine tool worktable 1. The mounting mechanism 6 is located on both sides of the long side of the mounting base 3, fixing the mounting base 3 to the machine tool worktable 1. The lateral clamping mechanism 5 is located at the lowest step on the upper surface of the mounting base 3. The lateral moving mechanism 4 is located on the vertical side of the mounting base 3, and its movement is determined by a square groove guide.

[0022] The mounting base 3 is square in shape. X / Y / Z directional references are reserved at the low step to determine the position of the whetstone at one time. M14-L30 countersunk screws 13 are installed on both sides of the mounting base 3. Three M10 through-hole threads are evenly distributed at the lowest step surface in the middle. A deep square groove is reserved on the side wall, which is directly opposite the threaded hole at the lowest step surface in the middle. M10-L10 threaded holes are reserved on the end face of the inner cavity of the square groove. The end face of the inner cavity of the square groove has a protruding annular feature, which serves as a guide post for the compression spring 9.

[0023] The lateral clamping mechanism 5 includes a lateral clamping plate 10, an M10-L25 countersunk screw 11, and an annular sealing ring 12. After the M10-L25 countersunk screw 11 is installed on the lateral clamping plate 10, the annular sealing ring 12 is installed on the threaded end of the M10-L25 countersunk screw. The annular sealing ring 12 needs to contact the lower end face of the lateral clamping plate 10. There are a total of 3 lateral clamping mechanisms 5 evenly distributed on one side of the whetstone 2.

[0024] The side clamping plate 10 has a 3mm lateral travel range when the top waist-shaped groove is installed with M10-L25 countersunk screws 11. The clamping surface is characterized by small rounded corners. It has line contact with the oilstone 2. The clamping surface facing feature is a combination of inclined surface and rounded corners. The rounded corners facilitate contact with the side moving block 7.

[0025] The lateral movement mechanism 4 includes an M10-L16 countersunk screw 8, a lateral movement block 7, and a compression spring 9.

[0026] The compression spring 9 is located between the mounting base 3 and the lateral moving block 7. The M10-L16 countersunk screw 8 contacts the lateral moving block 7 against the outer end face of the compression spring 9. When the M10-L16 countersunk screw 8 is turned clockwise, the lateral moving block 7 moves inward under the guidance of the lateral square groove of the mounting base 3, and the length of the compression spring 9 becomes shorter. When the M10-L16 countersunk screw 8 is turned counterclockwise, the lateral moving block 7 moves outward under the action of the compression spring 9, guided by the lateral square groove of the mounting base 3, and the length of the compression spring 9 becomes longer. The compression spring 9 is always in a compressed state.

[0027] Based on the layout of the lateral pressing mechanism 5, a total of 3 lateral moving mechanisms 4 are required.

[0028] The lateral moving block 7 has an inner cavity hole reserved in the center of one side on both sides of the large end face, which contacts the compression spring 9 and the upper plane of the small end plane of the mating surface of the side square groove of the mounting base 3. The scale lines are distributed every 1mm, and the scale line positions of the small upper end faces of the three lateral moving blocks 7 after installation must be consistent, further confirming that the position of the lateral pressing plate 10 in the lateral pressing mechanism 5 is consistent.

[0029] Mounting mechanism 6 includes M14-L30 countersunk screws 13 and T-nuts 14.

[0030] The above describes a flexible lateral clamping mechanism for mounting the whetstone. This mechanism is fixed in a position that will not interfere with machine tool processing. It is secured to the machine tool worktable 1 using M14-L30 countersunk screws 13 and T-nuts 14. The whetstone 2 is placed on the reference surface of the mounting base 3. The M10-L25 countersunk screws 11 are tightened clockwise, and the lateral clamping plate 10 clamps the whetstone 2. The M10-L25 countersunk screws 11 are loosened counterclockwise, and the lateral clamping plate 10 releases the whetstone 2 under the expansion of the annular sealing ring 12.

[0031] Note: The above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that any modifications or equivalent substitutions to the utility model without departing from the spirit and scope of the utility model should be covered within the scope of the claims of this utility model.
