Description

Technical Field

[0001] This utility model relates to the field of green body surface processing technology, and more specifically, it relates to a device for processing the surface of non-metallic green bodies. Background Technology

[0002] For non-metallic materials that require high-temperature firing, such as silicon carbide and alumina, pre-processing of the surface is necessary to ensure the flatness after high-temperature firing. Taking silicon carbide as an example, silicon carbide is a compound formed by carbon and silicon elements bonded by strong covalent bonds, possessing characteristics such as high-temperature stability, corrosion resistance, high hardness, and wear resistance. It is widely used in high-temperature kiln furniture applications. However, the surface of green slabs produced from silicon carbide plates is uneven and has large errors; after high-temperature firing, the flatness error remains significant, making it difficult to process.

[0003] Currently, most silicon carbide is processed using belt abrasives and brush grinders. Due to poor chip removal and easy chip accumulation during grinding, the machining allowance is small, the efficiency is low, and the flatness of the machined product is difficult to guarantee.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-6 As shown, this utility model provides a surface processing device for non-metallic material green blanks, including: a main frame 1, at least one gantry frame 2, and at least two fixed seats 3. A sliding component 4 that can slide along its lateral direction is slidably arranged on the main frame 1, and a fixing clamp 5 for fixing the non-metallic material green blank is provided on the sliding component 4; at least two fixed seats 3 are symmetrically arranged on both sides of the main frame 1 along its lateral direction; an up-and-down adjustment component 6 for adjusting the height of the gantry frame 2 is provided on the fixed seats 3; the two ends of at least one gantry frame 2 are fixedly connected to the up-and-down adjustment components 6 on at least two fixed seats 3 in a one-to-one correspondence; at least one electrically adjustable slide table 7 that can slide along its vertical direction is provided on the gantry frame 2; and at least one grinding component 8 for grinding the non-metallic material green blank is provided on the electrically adjustable slide table 7.

[0026] Specifically, the electrically adjustable slide 7 can move up and down the gantry frame 2, and the gantry frame 2 can be moved up and down via the up-and-down adjustment assembly 6. The silicon carbide plate to be processed is fixed on the fixed fixture 5, and then the grinding assembly 8 is started. Simultaneously, the sliding assembly 4 moves the fixed fixture 5 and the silicon carbide plate towards the grinding assembly 8. Grinding is performed on the bottom surface of the cutting abrasive 802 on the grinding assembly 8. When an increased grinding allowance is needed, the grinding assembly 8 is moved downwards via the up-and-down adjustment assembly 6 or the electrically adjustable slide 7, thus processing the plate in one pass. This not only ensures precision but also provides a large processing allowance, high automation, and improved processing efficiency. In practical applications, the horizontal axis corresponds to the x-axis of the coordinate system, the vertical axis corresponds to the y-axis, and the center axis corresponds to the z-axis.

[0027] Specifically, the gantry frame 2, two up-and-down adjustment components 6, and two fixed bases 3 are provided together. In practical applications, multiple gantry frames 2 and their supporting structures can be set up, such as two gantry frames 2, three gantry frames 2, or more, and processing operations can be carried out according to the requirements.

[0028] Furthermore, the fixing fixture 5 includes a substrate 501, a vacuum suction cup 502, and a magnet platform 503; the vacuum suction cup 502 is fixedly connected to the upper surface of the substrate 501; the magnet platform 503 is detachably mounted on the upper surface of the vacuum suction cup 502.

[0029] Specifically, when processing materials with high strength and large deformation, the magnet platform 503 is removed from the vacuum chuck 502, and the vacuum chuck 502 is used to hold the plate, thereby ensuring that the plate does not move during the processing.

[0030] When processing materials with low strength and small deformation, the material is directly placed on the magnet platform 503, and high-strength magnets 504 are placed around the material. The high-strength magnets 504 are fixed on the magnet platform 503. The high-strength magnets 504 around the material limit the material. At the same time, since the high-strength magnets 504 are thinner than the material to be processed, the cutting mold 802 cannot touch the strong magnets during the processing, thus ensuring that the material will not move during the processing.

[0031] Furthermore, the sliding assembly 4 includes a motor 401, a lead screw 402, two guide rails 403, at least one bearing mounting base 404, at least one slider 405, and a movable block 406;

[0032] The motor 401 is fixedly installed on the left side of the main frame. One end of the lead screw 402 is fixedly installed on the output end of the motor 401, and the other end of the lead screw 402 is rotatably installed on one of the bearing mounting seats 404. The movable block 406 is threadedly connected to the lead screw 402, and the top of the movable block 406 is fixedly installed at the middle position of the lower surface of the substrate 501. At least one slider 405 is divided into two groups and symmetrically fixedly installed on both sides of the substrate 501 along its transverse direction. Two guide rails 403 are symmetrically fixedly installed on the main frame, and the two groups of sliders 405 are slidably installed on the two guide rails 403 respectively.

[0033] To increase the stability of the lead screw 402, a bearing mounting seat 404 is added to the main frame 1. The bearing mounting seat 404 is fixedly mounted on the main frame 1, and the lead screw 402 is rotatably mounted on the bearing mounting seat 404 near the motor 401. At this time, the stability of the lead screw 402 can be improved by the action of the two bearing mounting seats 404. At the same time, a through hole is provided on the main frame 1 for one end of the lead screw 402 to pass through, which can not only meet the fixed connection between the lead screw 402 and the output end of the motor 401, but also meet the rotation of the lead screw 402.

[0034] Specifically, the motor 401 drives the lead screw 402 to rotate clockwise. During the clockwise rotation, the lead screw 402 cooperates with the movable block 406 to drive the fixed fixture 5 and the silicon carbide plate placed on the fixed fixture 5 to move towards the grinding assembly 8. The grinding assembly 8 then performs grinding on the silicon carbide plate on the fixed fixture 5.

[0035] Meanwhile, during the movement, the fixing clamp 5 can drive the two sets of sliders 405 to slide on the two guide rails 403 respectively. With the cooperation of the sliders 405 and the guide rails 403, the movement of the fixing clamp 5 is guided, preventing the fixing clamp 5 from deviating during the movement.

[0036] Furthermore, the up-down adjustment assembly 6 includes an adjustment seat 601, a threaded rod 602, a worm gear 603, at least two limiting screws 604, and at least one fixing nut 605;

[0037] The adjusting seat 601 is fixedly installed on the fixed seat 3. A worm gear, which mates with the worm 603, is rotatably mounted inside the adjusting seat 601. The worm gear has a threaded hole that mates with the threaded rod 602. The threaded rod 602 is threadedly connected to the worm gear through the threaded hole. One end of the threaded rod 602 passes through one end of the adjusting seat 601 and is fixedly connected to the middle of one end of the gantry frame 2. The other end of the threaded rod 602 passes through the other end of the adjusting seat 601 and the fixed seat 3 from top to bottom and extends to the bottom of the fixed seat 3. At least two limiting screws 604 are present. The adjusting seat 601 is symmetrically arranged on both sides of the gantry frame 2 along its vertical direction, and at least two limiting screws 604 pass through the fixing seat 3 and extend to the bottom of the fixing seat 3. At least one fixing nut 605 is divided into two groups and threadedly connected to the at least two limiting screws 604 respectively. The two fixing nuts 605 on each limiting screw 604 are located on the upper and lower sides of the fixing seat 3 respectively. The fixing seat 3 is provided with a through groove for the threaded rod 602 and the limiting screw 604 to pass through. The upper and lower ends of the adjusting seat 601 are provided with through grooves for the threaded rod 602 to pass through.

[0038] Specifically, rotating the worm gear 603 clockwise drives the worm wheel to rotate. During the rotation of the worm wheel, the threaded rod 602 moves upward through the threaded hole. As the threaded rod 602 moves upward, it can drive the gantry frame 2 to move upward. Similarly, rotating the worm gear 603 counterclockwise causes the gantry frame 2 to move downward. Therefore, rotating the worm gear 603 can adjust the height of the gantry frame 2. The cutting amount can be adjusted by changing the height of the gantry frame 2. At the same time, a device for real-time monitoring of the displacement of the grinding assembly 8 is installed on the gantry frame 2, which can know the processing amount in real time and facilitate adjustment. This is existing technology and will not be described in detail here.

[0039] The two ends of the gantry frame 2 need to maintain synchronous lifting during the lifting process. Two worm gears 603, which are symmetrically arranged below the two ends of the same gantry frame 2, are fixedly connected by a rotating shaft. The rotating shaft is rotatably installed on the main frame 1 and is located below the sliding component 4. The two do not interfere with each other. Under the action of the rotating shaft, the two worm gears 603 can rotate synchronously and the worm gears 603 can be supported, thereby preventing the worm gears 603 from being suspended in the air.

[0040] To facilitate the rotation of the worm gear 603, a handwheel is fixedly installed at the end of the worm gear 603 away from the main frame 1. When it is necessary to adjust the height of the gantry frame 2, either of the symmetrically arranged handwheels can be rotated to drive the two worm gears 603 to rotate synchronously.

[0041] Meanwhile, to facilitate the rotation of the worm gear 603, a drive motor can be installed on the end of either of the two worm gears 603 symmetrically arranged below both ends of the same gantry frame 2, away from the main frame 1. The drive motor drives the worm gear 603 to rotate, thereby realizing the electric adjustment of the height of the gantry frame 2.

[0042] During the lifting and lowering process, the gantry frame 2 drives the limit screw 604 to rise and fall. When the height of the gantry frame 2 is adjusted, the two fixing nuts 605 on the upper and lower sides of the fixed seat 3 on the limit screw 604 are rotated and moved to fit tightly against the fixed seat 3. With the cooperation of the two fixing nuts 605 and the limit screw 604, the position of the limit screw 604 is fixed, thereby preventing the threaded rod 602 and the gantry frame 2 from moving.

[0043] Furthermore, the grinding assembly 8 includes a grinding wheel motor 801 and a cutting grinding wheel 802; the grinding wheel motor 801 is vertically mounted on the electric adjusting slide 7; the cutting grinding wheel 802 is mounted on the output end of the grinding wheel motor 801.

[0044] Specifically, with the cooperation of the grinding motor 801 and the cutting grinding wheel 802, the silicon carbide plate that moves to the bottom of the cutting grinding wheel 802 via the sliding component 4 can be ground. Under the action of the electric adjusting slide 7, the grinding advance and retreat function can be realized.

[0045] In this utility model, the cutting abrasive 802 can adopt a discontinuous peripheral tooth structure of a diamond grinding wheel. The teeth of this diamond grinding wheel are simple to manufacture, have stable quality, are easy to weld, have high production efficiency, are easy to remove chips, have good cooling conditions, have high grinding wheel durability, are easy to adjust the machining amount, and have a large machining allowance.

[0046] There are two gantry frames 2 and four fixed seats 3. The four fixed seats 3 are arranged symmetrically in two groups on both sides of the main frame 1 along its horizontal direction. The two fixed seats 3 in each group are integrally formed. The two ends of the two gantry frames 2 are fixedly connected to the up and down adjustment components 6 on the two groups of fixed seats 3. An electric adjustment slide 7 that can slide along its vertical direction is provided on one side of the gantry frame 2. Two electric adjustment slides 7 that can slide along their vertical direction are provided on the other side of the gantry frame 2. Each electric adjustment slide 7 is equipped with a grinding component 8 for grinding non-metallic material blanks.

[0047] By setting multiple grinding components 8, different types of cutting abrasives 802 can be set on multiple grinding components 8. Different types of cutting abrasives 802 can be used in different combinations, and different moving speeds can be combined according to different types of cutting abrasives 802, thereby achieving rough grinding and fine grinding.

[0048] The grinding assembly 8 can also be configured with grinding wheel motors 801 of different machining precision and cutting grinding wheels 802 of different mesh sizes according to actual requirements, so as to achieve different pre-machining requirements.

[0049] Meanwhile, the electric adjustment slide 7 or the up-and-down adjustment component 6 can achieve the consistency of flatness when multiple cutting abrasives 802 are combined. When the wear of the cutting abrasives 802 is different, the position of the cutting abrasives 802 can be flexibly adjusted by the electric adjustment slide 7.

[0050] Furthermore, a dust cover 9 is provided on the outside of the gantry frame 2; the bottom ends of the dust cover 9 are symmetrically fixed to both sides of the main frame 1 along its transverse direction.

[0051] Specifically, a dust cover 9 is installed on the main frame 1 to prevent dust from leaking out. Since the grinding dust is very fine, a dust collector can also be configured as needed to prevent dust from leaking out and to protect personal safety.

[0052] In summary, this utility model provides a surface processing device for non-metallic material blanks. During use, the silicon carbide plate to be processed is placed on the fixed fixture 5 and fixed using a vacuum suction cup 502 or by a high-strength magnet 504 in conjunction with a magnet platform 503. Then, the grinding assembly 8 is started, and simultaneously the motor 401 drives the lead screw 402 to rotate clockwise. During this clockwise rotation, the lead screw 402, in conjunction with the movable block 406, moves the fixed fixture 5 and the silicon carbide plate towards the grinding assembly 8. The cutting abrasive 802 on the grinding assembly 8 then grinds the silicon carbide plate. In the machining process, when it is necessary to increase the grinding allowance, the gantry frame 2 is moved downward by the up-down adjustment component 6, so that the grinding component 8 moves downward with the gantry frame 2. Alternatively, the grinding component 8 is moved downward by the electric adjustment slide table 7, so that plates of different sizes can be processed in one go. After processing is completed, the sliding component 4 continues to move forward. After reaching the designated position, the processed silicon carbide plate is removed manually or by other devices. After removal, the motor 401 drives the lead screw 402 to rotate counterclockwise, so that the sliding component 4, with the fixed clamp 5, returns to the origin and repeats the next operation.

[0053] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
