Description

Technical Field

[0001] This utility model relates to the field of grinding wheel production technology, and in particular to a clamping structure for grinding wheel production. Background Technology

[0002] Grinding wheels, also known as bonded abrasives, are abrasives in which ordinary abrasive grains are bonded together with a bonding agent to form a specific shape and possess a certain strength. They generally consist of abrasive grains, a bonding agent, and pores; these three parts are often referred to as the three essential elements of bonded abrasives. Grinding wheels are the most widely used and extensive type of abrasive. During operation, they rotate at high speeds and can perform rough grinding, semi-finishing, and finish grinding, as well as grooving and cutting, on the outer and inner diameters, planes, and various profiles of metal or non-metal workpieces. In the production process of diamond grinding wheels, fixed fixtures are often required to hold them for dressing, shaping, assembly, or cleaning. However, existing fixtures are not universally compatible, necessitating the use of different fixtures for different parts of the grinding wheel during processing, which is quite cumbersome.

[0003] For example, a clamping structure for grinding wheel production disclosed in Chinese patent literature (publication number: CN219704702U) utilizes a drive structure and a clamping structure. The movable end of the electric cylinder structure drives the electric push rod to move up and down, allowing the clamping arc plate to be adjusted according to the diameter of the grinding wheel to be clamped. In addition, the electric push rod can drive the movable arc plate on the inner side of the clamping arc plate to be adjusted according to the thickness of the grinding wheel to be clamped. This allows the clamping structure to adapt to grinding wheels of different sizes, and the clamp does not obstruct the center hole of the grinding wheel, thereby improving the practicality of the clamp.

[0004] However, this mechanism is only suitable for machining the inner ring of the grinding wheel. When machining the outer ring of the grinding wheel, due to the obstruction of the clamping mechanism, it is necessary not only to manually rotate the rotating shaft, but also to repeatedly adjust the clamping position in order to machine the obstructed part, which makes the operation cumbersome and reduces the machining efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for repeated adjustment of the clamping position during grinding wheel processing, which reduces processing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fixture structure for grinding wheel production includes a processing table, the processing table having an inner and outer clamping mechanism inside, and the inner and outer clamping mechanism including a drive disk, the drive disk being rotatably connected to the inner wall of the processing table via a bearing.

[0008] The upper end of the drive disk is provided with inclined grooves arranged in a ring array, the upper end of the processing table is provided with through grooves arranged in a ring array, the inner bottom wall of the processing table is provided with limiting slide grooves arranged in a ring array, the inner wall of the limiting slide groove is slidably connected to a limiting slider, and the upper end of the limiting slider is fixedly connected to a slide rod.

[0009] Preferably, the outer side of the slide rod is slidably connected to the inner wall of the inclined groove and the through groove, respectively, and the upper end of the slide rod extends to the top of the processing table and is fixedly connected to a movable plate.

[0010] Preferably, an L-shaped support block is fixedly connected to the upper end of the movable plate, and a first arc-shaped clamping block is fixedly connected to the upper end of the L-shaped support block.

[0011] Preferably, a second arc-shaped clamping block is fixedly connected to the upper end of the movable plate, and a support plate is fixedly connected to the outer surface of the second arc-shaped clamping block.

[0012] Preferably, the inner bottom wall of the processing table is rotatably connected to a drive rod via a bearing, and the upper end of the drive rod is fixedly connected to the center of the lower end of the drive disk.

[0013] Preferably, a worm gear is fixedly sleeved on the outside of the drive rod, and a servo motor is fixedly installed on the inner bottom wall of the processing table.

[0014] Preferably, the output shaft of the servo motor is fixedly mounted with a worm gear via a coupling, and the outer surface of the worm gear meshes with the tooth surface of the worm wheel.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the inner and outer clamping mechanisms enable clamping of different parts of the grinding wheel. The L-shaped support block, in conjunction with the first arc-shaped clamping block, clamps the outer side of the grinding wheel for machining the center hole. The second arc-shaped clamping block, in conjunction with the support plate, fixes the center hole of the grinding wheel, facilitating machining of the outer side of the grinding wheel. This eliminates the need for frequent fixture changes, improving machining convenience and efficiency. Furthermore, the servo motor drives the drive disc to rotate via a worm gear transmission, thereby causing the sliding rod, moving plate, and other components to move. This achieves automatic adjustment of the first and second arc-shaped clamping blocks, which is more precise and efficient than manual adjustment, reducing the intensity and time of manual operation.

[0026] Example

[0027] like Figure 1-4As shown, this utility model provides a technical solution: a fixture structure for grinding wheel production, including a processing table 1, which is cast from high-strength alloy steel. The processing table 1 has an internal and external clamping mechanism, which is the key part for clamping different parts of the grinding wheel. The internal and external clamping mechanism includes a drive disk 2, which is made of high-quality alloy steel. The drive disk 2 is rotatably connected to the inner wall of the processing table 1 through a high-precision bearing. The bearing can ensure that the drive disk 2 rotates flexibly and with high precision, reduce friction loss, and extend service life.

[0028] The upper end of the drive disk 2 is provided with inclined grooves 214 arranged in a ring array. These inclined grooves 214 are guide structures for the movement of the slide rod 24. The upper end of the processing table 1 is provided with through grooves 21 arranged in a ring array. The through grooves 21 provide a space channel for the movement of the slide rod 24. The inner bottom wall of the processing table 1 is provided with limiting grooves 22 arranged in a ring array. The limiting grooves 22 are milled by high-precision processing equipment and have smooth inner walls. Their function is to limit the movement direction of the limiting slider 23. The limiting slider 23 is slidably connected to the inner wall of the limiting groove 22. The limiting slider 23 and the limiting groove 22 are tightly matched and can slide smoothly in the groove. The upper end of the limiting slider 23 is fixedly connected to the slide rod 24 by welding. The slide rod 24 is made of high-strength stainless steel and has good strength and corrosion resistance.

[0029] The outer side of the slide rod 24 is slidably connected to the inner wall of the inclined groove 214 and the through groove 21 respectively. This connection method allows the slide rod 24 to move along a specific trajectory when the drive disk 2 rotates. The upper end of the slide rod 24 extends to the top of the processing table 1 and is fixedly connected to the moving plate 25 by bolts. The moving plate 25 is made of high-strength steel plate and is flattened to ensure that it is firmly connected to the slide rod 24 and has a small amount of deformation.

[0030] An L-shaped support block 26 is fixedly connected to the upper end of the movable plate 25 by welding. The L-shaped support block 26 is made of high-strength alloy steel and its shape design conforms to the mechanical principle, which can stably support the grinding wheel. A first arc-shaped clamping block 27 is fixedly connected to the upper end of the L-shaped support block 26 by bolts. The inner surface of the first arc-shaped clamping block 27 is finely polished, which can provide a good fit when in contact with the outer side of the grinding wheel, avoiding damage to the surface of the grinding wheel. It is also made of wear-resistant material to ensure the reliability of long-term use.

[0031] The upper end of the movable plate 25 is fixedly connected to a second arc-shaped clamping block 28 by welding. The shape of the second arc-shaped clamping block 28 is adapted to the center hole of the grinding wheel. Its outer surface is treated with rust prevention. The outer surface of the second arc-shaped clamping block 28 is fixedly connected to a support plate 29 by welding. The support plate 29 provides a stable support surface for the grinding wheel, ensuring that the center hole of the grinding wheel can be firmly fixed when the outer side of the grinding wheel is processed.

[0032] The inner bottom wall of the processing table 1 is rotatably connected to the drive rod 210 through a high-precision bearing. The bearing can ensure the smoothness and accuracy of the rotation of the drive rod 210. The upper end of the drive rod 210 is fixedly connected to the lower center of the drive disk 2 by welding. This connection method can ensure that the drive rod 210 can accurately drive the drive disk 2 to rotate synchronously when it rotates.

[0033] The drive rod 210 is fixedly sleeved with a worm gear 211 by an interference fit. The worm gear 211 is made of high-strength bronze material and has been precision machined and tooth surface treated, which has good wear resistance and transmission accuracy. The inner bottom wall of the processing table 1 is fixedly installed with a servo motor 212 by bolts. The servo motor 212 can provide precise power output to meet the needs of the fixture for clamping and adjusting grinding wheels of different sizes.

[0034] The output shaft of the servo motor 212 is fixedly mounted with a worm gear 213 via a coupling. The coupling ensures that the power of the servo motor 212 is accurately transmitted to the worm gear 213. The outer surface of the worm gear 213 meshes with the tooth surface of the worm wheel 211, accurately transmitting the rotational motion of the servo motor 212 to the drive rod 210, thereby driving the drive disk 2 to rotate and realize the automatic clamping and adjustment of the grinding wheel.

[0035] The working process of this utility model:

[0036] Step 1: Start the servo motor 212. The output shaft of the servo motor 212 drives the worm 213 to rotate. The worm 213 meshes with the worm wheel 211, causing the worm wheel 211 to drive the drive rod 210 to rotate, which in turn drives the disk 2 to rotate. The inclined groove 214 on the drive disk 2 cooperates with the slide rod 24. As the drive disk 2 rotates, the slide rod 24 slides in the inclined groove 214 and the through groove 21. Under the restriction of the limiting slider 23 and the limiting groove 22, the slide rod 24 can only move in a specific direction, thereby driving the moving plate 25 to move upward. The moving plate 25 drives the L-shaped support block and the first arc-shaped clamping block 27 to move upward. The multiple first arc-shaped clamping blocks 27 move relative to each other to clamp and fix the outer side of the grinding wheel placed on the L-shaped support block so as to process the center hole of the grinding wheel.

[0037] Step two: Pass the center hole of the grinding wheel through multiple second arc-shaped clamping blocks 28 and support it with the support plate 29. Start the servo motor 212 again to drive the disk 2 to rotate in the opposite direction. The slide rod 24 drives the moving plate 25 to move downward, so that the multiple second arc-shaped clamping blocks 28 move away from each other, thereby fixing the center hole of the grinding wheel. At this time, the outer side of the grinding wheel can be processed.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
