[0002] Angle grinding disc is a resin abrasive tool with special fiber fabric as reinforcement material. Angle grinding disc has high tensile, impact and bending strength. Angle grinding disc is widely used in grinding and rust removal of various metal and non-metal materials. It is fast and economical. The steps of angle grinding disc production process are as follows: 1. Material preparation: Select suitable alloy materials as the base material of the grinding disc, common ones are steel, iron, tungsten carbide, etc. At the same time, prepare other auxiliary materials, such as binders, fillers, etc. 2. Formula design: Design a suitable formula according to grinding requirements and material properties. The formula includes the proportion of alloy materials, the type and content of binders, etc. 3. Mixing: Mix the alloy materials, binders and fillers evenly according to the formula ratio. You can use stirring equipment or manual mixing. 4. Pressing: Put the mixed material into the mold and press it into shape. The temperature and pressure need to be controlled during the pressing process to ensure the density and strength of the grinding disc. 5. Sintering: Put the formed grinding disc into a high-temperature furnace for sintering. The sintering temperature and time are regulated according to the characteristics and requirements of the material. During the sintering process, the material particles will combine with each other to form a solid structure. 6. Finishing: The sintered grinding disc needs to be finished, including trimming the edges, grinding the surface and other steps to ensure that the size and surface quality of the grinding disc meet the requirements. During finishing, the angle grinding disc needs to be clamped with a fixture for finishing. The existing angle grinding disc is clamped by the upper and lower clamps, and is equipped with a spacing adjustment piece connecting the two clamps, and the spacing adjustment piece will be set on one side of the angle grinding disc. If the circumference of the angle grinding disc is finished, it is necessary to adjust the angle of the angle grinding disc relative to the spacing adjustment piece, which is easy to affect the processing of the angle grinding disc. For this reason, a kind of angle grinding disc processing fixture is designed to facilitate penetrating from the middle of the angle grinding disc and clamping the angle grinding disc to ensure that the circumference of the angle grinding disc is fully exposed, which is convenient for circumferential processing of the angle grinding disc.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Example:
[0022] See also Figure 1-4A clamp for processing angle grinding discs comprises a sliding column 1, on which a telescopic clamp frame and a support plate 6 are sleeved, the telescopic clamp frame comprises a fixed sleeve 2 and a sliding sleeve 3 circumferentially connected with a plurality of V-shaped clamp chains, the V-shaped clamp chain comprises an articulated rod 1 4 and an articulated rod 2 5 hinged to each other at one end, the other ends of the articulated rod 1 4 and the articulated rod 2 5 are respectively hinged to the fixed sleeve 2 and the sliding sleeve 3, the fixed sleeve 2 and the sliding sleeve 3 are both sleeved on the sliding column 1, and the fixed sleeve 2 is fixed on the sliding column 1, the sliding sleeve 3 is slidably connected to the sliding column 1 and is arranged on a side close to the support plate 6, and a locking mechanism compatible with the sliding column 1 is arranged on the side of the support plate 6 away from the telescopic clamp frame, and an elastic mechanism is connected between the sliding sleeve 3 and the support plate 6. Furthermore, a plurality of V-shaped clamp chains are evenly distributed circumferentially between the fixed sleeve 2 and the sliding sleeve 3 to increase the stability of clamping the angle grinding disc.
[0023] Specifically, the locking mechanism includes a threaded sleeve 8 connected to the side of the support plate 6 away from the telescopic clamp, and an external thread 7 compatible with the threaded sleeve 8 is fixedly connected to the sliding column 1. Through the cooperation of the external thread 7 and the threaded sleeve 8, the threaded sleeve 8 is rotated clockwise or counterclockwise, and with the cooperation of the external thread 7, the support plate 6 is driven to move to the side close to the telescopic clamp or away from the telescopic clamp, thereby facilitating the compression or stretching of the telescopic clamp. After compression, the circumferential area increases and the length shortens. When stretched, the circumferential area decreases and the length increases.
[0024] Specifically, the fixed sleeve 2 is fixedly connected to the sliding column 1, and a rotating ring table 11 is fixedly connected to the side of the threaded sleeve 8 close to the telescopic clamp, which is slidably matched with the sliding column 1 and rotatably matched with the support plate 6. When the fixed sleeve 2 is fixedly connected to the sliding column 1, the telescopic clamp can only be telescopically moved up and down to avoid circumferential rotation. The setting of the rotating ring table 11 makes it easy to avoid the angle grinding disc placed on the support plate 6 from rotating when the threaded sleeve 8 is rotated, especially to overcome the circumferential rotation of the angle grinding disc when the telescopic clamp clamps the angle grinding disc, thereby reducing the circumferential friction of the angle grinding disc and avoiding scratches on the angle grinding disc.
[0025] Specifically, the elastic mechanism includes a spring 13, and a slip ring 12 is fixedly connected to one side of the sliding sleeve 3 close to the support plate 6. The spring 13 is sleeved on the sliding column 1 and is located between the slip ring 12 and the support plate 6, and the two sides of the spring 13 are respectively fixedly connected to the slip ring 12 and the support plate 6. The arrangement of the slip ring 12 and the spring 13 facilitates the connection between the support plate 6 and the sliding sleeve 3. Since the spring 13 has elastic potential energy, it is convenient for connection and can buffer the clamping force of the diagonal grinding disc of the telescopic clamp, thereby ensuring the stability of the clamping and avoiding excessive clamping force.
[0026] Specifically, one end of the slide column 1 away from the telescopic clamp is fixedly connected with a base 9. The base 9 is provided to facilitate supporting the slide column 1 so that the slide column 1 is in a vertical state, making it convenient to put the angle grinding disc through the telescopic clamp.
[0027] Specifically, the inner bottom of the base 9 is fixedly connected with a fixing frame 10 which is fixedly connected to the sliding column 1 . By providing the fixing frame 10 , a supporting point is added to further ensure the stability of the sliding column 1 .
[0028] When in use, the angle grinding disc is passed through the telescopic clamp and placed on the support plate 6. The locking mechanism can push the support plate 6 toward the telescopic clamp, thereby driving the sliding sleeve 3 to push toward the fixed sleeve 2, so that multiple V-shaped clamp chains can be propped up outward, so that multiple hinged rods 5 are above the angle grinding disc and clamp the angle grinding disc with the support plate 6 arranged below the angle grinding disc.
