Description

Technical Field

[0001] The utility model relates to the technical field of silicon carbide grinding, and more specifically, to a silicon carbide grinding device. Background Art

[0002] Silicon carbide is an inorganic substance with the chemical formula SiC. It is made of raw materials such as quartz sand, petroleum coke (or coal coke), sawdust (salt is needed when producing green silicon carbide) through high-temperature smelting in a resistance furnace. Silicon carbide is a semiconductor that exists in nature in the form of the extremely rare mineral moissanite. Since 1893, it has been mass-produced as powder and crystals for use as abrasives, etc. Among non-oxide high-tech refractory raw materials such as C, N, and B, silicon carbide is the most widely used and economical one, which can be called diamond sand or refractory sand. China's industrially produced silicon carbide is divided into black silicon carbide and green silicon carbide; at present, most silicon carbide needs to remove particles and impurities on the surface after processing to obtain a flat surface. For this purpose, a silicon carbide grinding device is proposed.

[0003] After searching, for example, a Chinese patent application with application number CN202321527317.1 discloses a grinding device for silicon carbide processing, which can be adjusted according to the size of silicon carbide by setting a support frame, a threaded adjustment bolt and a fastening clamp. The threaded adjustment bolt on the inner side of the support frame is twisted with a telescopic thread, thereby driving the fastening clamp to adjust the telescopic position, so that the fastening clamp can clamp and fix silicon carbide of different sizes, thereby improving the practicality of the device; the grinding head connection mechanism, when installing the grinding head of the device, insert the grinding head into the inner side of the connecting column, and then twist the locking bolt at the top of the outer side of the connecting column, so that the locking bolt penetrates and inserts into the inner side of the connecting column, thereby being threadedly locked and fixed with the locking hole at the top of the outer side of the grinding head, the structure is simple, and the time for installation and replacement of the grinding head of the device is reduced.

[0004] However, when the above technical solution is used, the silicon carbide can only be fixed for grinding, so that only the silicon carbide plane can be ground. However, when the bevel of the silicon carbide needs to be ground, the silicon carbide can only be disassembled and repositioned for fixing, which delays work efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a silicon carbide grinding device. The technical problem to be solved by the present invention is: being able to perform bevel grinding on silicon carbide and reducing unnecessary disassembly processes.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a silicon carbide grinding device, comprising an operating table:

[0007] A limited sliding groove is provided inside the operating table, a sliding block is movably provided inside the limited sliding groove, and a support column is fixed on the upper end of the sliding block;

[0008] A grinding adjustment device capable of adjusting the grinding position is provided at the upper end of the operating table, which is used to adjust the grinding position laterally;

[0009] The grinding adjustment device comprises two fixing plates, which are respectively fixedly arranged at the upper ends of the operating table, and two limiting rods are fixedly arranged between the fixing plates;

[0010] The upper end of the support column is provided with a clamping and rotating device capable of clamping silicon carbide, which is used to clamp the silicon carbide for rotation.

[0014] In a preferred embodiment, the clamping and rotating device includes a rotating motor, the rotating motor is fixedly arranged at the upper end of the supporting column, and a fixing frame is fixedly arranged at the output end of the rotating motor.

[0015] In a preferred embodiment, sliding rods are passed through both sides of the fixing frame, two rotating threaded columns are threadedly passed through both sides of the fixing frame, and two clamps are connected between the two rotating threaded columns through movable connecting pieces.

[0016] In a preferred embodiment, the sliding rod is fixedly connected to the outer sides of the two clamps respectively.

[0017] Technical effects and advantages of the utility model:

[0018] The utility model is provided with a grinding adjustment device, which is conducive to horizontally adjusting the grinding position, so that the grinder can be conveniently adjusted to a suitable position. The second threaded sleeve in the moving block is threadedly connected to the second threaded column. Therefore, when the position of the grinder needs to be adjusted, the second threaded column is driven to rotate by rotating the rotating handle, thereby achieving the effect of adjusting the position of the grinder. Because the moving block is movably penetrated by two limit rods, the moving block is limited, so that the moving block moves smoothly. The output end of the grinder is convex, so it can be adjusted to the silicon carbide bevel position;

[0019] The utility model is provided with a clamping and rotating device, which is conducive to clamping silicon carbide for rotation, so that silicon carbide can be grinded at an angle. The fixing frame is driven to rotate by a rotating motor, and the clamp in the fixing frame is extruded due to the rotation of the rotating threaded column. The clamp is limited by the sliding rod during the extrusion process, thereby achieving the effect of stably clamping silicon carbide. When the fixing frame rotates, it can drive the silicon carbide to rotate, thereby achieving the effect of bevel circular grinding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] 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 them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field of silicon carbide grinding without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 and 2 As shown, the utility model provides a silicon carbide grinding device, including an operating table 1: a limited sliding groove 6 is provided on the inner side of the operating table 1, a sliding block 7 is movably provided on the inner side of the limited sliding groove 6, a support column 8 is fixedly provided on the upper end of the sliding block 7, a first threaded column 4 is penetrated by the inner groove of the operating table 1, a movable connecting seat 5 is movably provided at one end of the first threaded column 4, one side of the movable connecting seat 5 is fixedly connected to the sliding block 7, a first threaded sleeve 9 is fixedly provided on the inner wall of the inner groove of the operating table 1, and the first threaded sleeve 9 is threadedly connected to the first threaded column 4.

[0027] In order to be able to adjust the grinding position laterally, a grinding adjustment device 2 capable of adjusting the grinding position is provided at the upper end of the operating table 1, which is used to adjust the grinding position laterally;

[0028] like Figure 3 As shown, the grinding adjustment device 2 includes two fixed plates 21, the two fixed plates 21 are respectively fixedly arranged on the upper end of the operating table 1, two limit rods 23 are fixedly arranged between the fixed plates 21, a second threaded column 22 is penetrated between the two fixed plates 21 through a movable limiter, a rotating handle 26 is fixedly arranged at one end of the second threaded column 22, a second threaded sleeve 25 is threadedly connected to the outer surface of the second threaded sleeve 25, a moving block 24 is fixedly arranged on the outer surface of the second threaded sleeve 25, and the two limit rods 23 respectively penetrate the lower end of the moving block 24, and the moving block 24 is moved. A grinder 27 is fixedly provided on the upper end of the block 24, and is threadedly connected to the second threaded column 22 through a second threaded sleeve 25 in the moving block 24. Therefore, when the position of the grinder 27 needs to be adjusted, the second threaded column 22 is driven to rotate by rotating the rotating handle 26, thereby achieving the effect of adjusting the position of the grinder 27. Since the moving block 24 is movably penetrated by two limit rods 23, the moving block 24 is limited so that the moving block 24 moves smoothly. The output end of the grinder 27 is convex, so it can be adjusted to the silicon carbide bevel position.

[0029] Furthermore, in order to be able to clamp the silicon carbide for rotation, a clamping and rotating device 3 capable of clamping the silicon carbide is provided at the upper end of the support column 8, which is used to clamp the silicon carbide for rotation;

[0030] like Figure 4As shown, the clamping and rotating device 3 includes a rotating motor 31, which is fixedly arranged at the upper end of the supporting column 8, and a fixing frame 32 is fixedly arranged at the output end of the rotating motor 31. Slide rods 34 are penetrated on both sides of the fixing frame 32, and two rotating threaded columns 33 are respectively threadedly penetrated on both sides of the fixing frame 32. Two clamps 35 are respectively connected between the two rotating threaded columns 33 through movable connecting parts, and the slide rods 34 are respectively fixedly connected to the outer sides of the two clamps 35. The fixing frame 32 is driven to rotate by the rotating motor 31, and the clamps 35 in the fixing frame 32 are extruded due to the rotation of the rotating threaded columns 33. The clamps 35 are limited by the slide rods 34 during the extrusion process, thereby achieving the effect of stably clamping silicon carbide. When the fixing frame 32 rotates, it can drive the silicon carbide to rotate, thereby achieving the effect of bevel circular grinding.

[0031] The working principle is as follows: when the utility model is used for grinding the silicon carbide plane, the silicon carbide is clamped by the clamping and rotating device 3, the rotating motor 31 is turned off, and the grinder 27 is started to rotate, and the first threaded column 4 is rotated, and the first threaded column 4 is threadedly connected with the first threaded sleeve 9, so that the top sliding block 7 is moved forward, so that the silicon carbide contacts the output end of the grinder 27. When the utility model is used for grinding the silicon carbide bevel, the grinding position of the grinder 27 is adjusted according to the grinding adjustment device 2, so that the output end of the grinder 27 contacts the silicon carbide bevel, and the grinder 27 is started. The clamping and rotating effect of the clamping and rotating device 3 drives the silicon carbide to rotate slowly, thereby achieving the bevel grinding effect of the silicon carbide.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
