At this time, the sliding shaft cannot move with the driving plate under the limitation of the strip groove, but will be retracted along the strip groove under the extrusion of the extrusion chute, thereby stretching the reset tension spring, completing the fixation of the cylindrical alumina ceramic part.

At this time, the driven gear plate is separated from the fixed gear plate. At this time, the extrusion pressure of the extrusion groove on the sliding shaft disappears, and the reset spring restores its deformation. Under the action of the pulling force of the sliding shaft, the clamping rod moves outward, thereby facilitating the circulation of the alumina ceramic parts. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-5 As shown, a ceramic edge grinding device for ceramic production includes a workbench 1, a loading assembly is arranged on one side of the workbench 1, and a grinding assembly is arranged on the other side;

[0030] The loading assembly includes a loading plate 2 rotatably arranged on a workbench 1, four groups of guide grooves 3 equally spaced around the axis of the loading plate 2, and the guide groove 3 is composed of three strip grooves equally spaced around the same center of a circle, a sliding shaft 4 slidably arranged inside the guide groove 3, a clamping rod 5 arranged at the top of the sliding shaft 4 for fixing the ceramic piece, a flat groove is provided on the outer surface of the clamping rod 5 close to the ceramic piece, and a rubber pad is laid on the surface of the flat groove in contact with the ceramic piece, a driving plate 6 matching the guide groove 3 is rotatably arranged at the bottom of the loading plate 2, an extrusion groove 7 matching the strip groove is provided on the driving plate 6, and the bottom end of the sliding shaft 4 passes through the extrusion groove 7, and a driven gear plate 8 is provided at the bottom of the driving plate 6. , a side plate No. 1 9 is arranged on one side of the sliding shaft 4, a side plate No. 2 10 matching the side plate No. 1 9 is arranged at the bottom of the loading plate 2, a return spring 11 is arranged between the side plate No. 2 10 and the side plate No. 1 9, a low-speed motor 12 for driving the loading plate 2 to rotate is arranged at the bottom of the workbench 1, and the grinding assembly includes a fixed toothed disc 14 for driving the driven toothed disc 8 to rotate, the loading plate 2 (diameter Φ900mm) is driven by the low-speed motor 12 (speed 0.5-5r / min), and the disc surface is provided with four groups of guide grooves 3 distributed at 90° equidistantly, and each group of guide grooves 3 is composed of three strip grooves spaced 120° apart (groove width 30mm), and the sliding shaft 4 (diameter Φ, 29mm, hard chrome plated surface) is distributed The extrusion slide groove 7 runs through the strip groove and the driving disk 6, and the clamping rod body 5 is welded on the top. The plane groove is provided with a 3mm thick rubber pad (Shore hardness 40HA). The driven toothed disc 8 (module 1.5, number of teeth 180) at the bottom of the driving disk 6 can mesh with the fixed toothed disc 14. When the driven toothed disc 8 is disengaged from the fixed toothed disc 14, the sliding shaft 4 realizes radial adaptive contraction through the reset tension spring 11 (stiffness coefficient 5N / mm), which can realize the reset of the clamping rod body 5. When the device is grinding the cylindrical alumina ceramic part, the staff can put the cylindrical alumina ceramic part between the three clamping rod bodies 5, and then start the low-speed motor 12 to drive the loading disc 2 to rotate. The bottom of the loading disc 2 rotates during the rotation. The four sets of driven toothed discs 8 are periodically meshed with the fixed toothed discs 14. As the loading disc 2 rotates, the driven toothed discs 8 rotate in one direction under the action of the fixed toothed discs 14, and the driving disc 6 is synchronously driven to rotate. The extrusion chute 7 on the driving disc 6 also deviates at this time. At this time, the sliding shaft 4 cannot move with the driving disc 6 under the limitation of the strip groove, but will be squeezed along the strip groove under the extrusion of the extrusion chute 7, thereby stretching the reset spring 11. At this time, the cylindrical alumina ceramic part is fixed. The clamping rod 5 can form a three-point flexible clamping for the alumina ceramic part. The three-point arc chute cooperates with the silicone rubber pad to make the clamping stress evenly distributed, and the contact pressure is ≤0.5MPa, which is 90% lower than that of traditional rigid clamps, avoiding micro cracks on the edge of alumina ceramics. After grinding, the low-speed motor 12 drives the loading plate 2 to continue rotating. At this time, the driven gear plate 8 is separated from the fixed gear plate 14. At this time, the extrusion force of the extrusion chute 7 on the sliding shaft 4 disappears, and the reset tension spring 11 recovers its deformation. Under the action of the pulling force of the sliding shaft 4, the clamping rod 5 moves outward, thereby facilitating the circulation of the alumina ceramic parts. .

[0031] In the present embodiment, specifically, there is a certain gap between the end faces of the driving disc 6 and the driven gear disc 8 that are close to each other, a limit block is set at the bottom end of the sliding shaft 4, and the limit block is located in the gap. The set limit block can be used to limit the sliding shaft 4 when it moves, thereby preventing the bottom end of the sliding shaft 4 from detaching from the extrusion groove 7, thereby ensuring the stability of the sliding shaft 4 during movement.

[0032] In this embodiment, specifically, the grinding assembly also includes a base 13 arranged on the table surface of the workbench 1, the bottom wall of the base 13 is connected to the fixed gear disc 14, a lifting frame 15 is arranged on the top of the low-speed motor 12, and a lifting slide 16 with horizontal and vertical distribution is opened on the inner side of the lifting frame 15, and a No. 1 motor 17 is arranged on the top of the lifting frame 15, and a lifting screw 18 connected to the No. 1 motor 17 is arranged on the top of the base 13, and a lifting seat 19 is connected to the outer side of the lifting screw 18 through a thread, and the two ends of the lifting seat 19 are engaged with the side of the lifting frame 15, and a liftable transverse frame 20 is arranged on the lifting frame 15, and the transverse moving frame 20 can be lifted and lowered. The frame 20 is connected to the lifting seat 19, and a horizontally distributed transverse sliding groove 21 is provided on the inner side of the transverse moving frame 20. A transverse moving seat 22 for fixing a grinding motor 23 is slidably arranged inside the transverse moving groove 21, and a grinding disc 24 is arranged at the output end of the grinding motor 23. A guide slide bar 25 and a transverse moving screw 26 are arranged inside the transverse moving frame 20, and the transverse moving screw 26 is rotatably connected to the transverse moving frame 20. A connecting slider 27 is movably arranged on the outer side of the guide slide bar 25 and the transverse moving screw 26, and the connecting slider 27 is threadedly connected to the transverse moving screw 26, and the connecting slider 27 is connected to the transverse moving seat 22. One side of the transverse moving frame 20 A second motor 28 is provided at the end for driving the traverse screw 26 to rotate. When grinding the cylindrical alumina ceramic piece, the staff can start the first motor 17 according to the height of the ceramic piece, and drive the lifting screw 18 to rotate through the first motor 17. The lifting screw 18 can be used to control the lifting and lowering of the lifting seat 19 and the traverse frame 20, so as to adjust the height of the grinding motor 23. The two ends of the lifting seat 19 are engaged with the side of the lifting frame 15, which can play a good limiting role and ensure the stability of the lifting seat 19 during movement. According to the opening diameter of the cylindrical alumina ceramic piece, the staff can start the second motor The machine 28 utilizes the No. 2 motor 28 to drive the transverse screw 26 to rotate, and the transverse screw 26 drives the connecting slider 27 and the transverse seat 22 to move horizontally, so as to adjust the lateral position of the grinding motor 23, so as to perform edge grinding operations on alumina ceramic parts of different diameters. The guide slide bar 25 forms a limit guide for the movement of the connecting slider 27, thereby ensuring the stability of the transverse seat 22 during movement. The grinding disc 24 is made of diamond, and its particle size gradient matching technology (coarse grinding #200→fine grinding #800) increases the single processing efficiency by 40%, and the surface integrity is better than the traditional multi-machine sequential processing.

[0033] The device can be equipped with a circulating water cooling system (flow rate 5L / min) when in use. The water cooling system can be used to spray coolant into the grinding area to control the grinding temperature to less than 80°C to avoid phase embrittlement of alumina ceramics caused by local overheating (>150°C). The workbench 1 is equipped with an integrated negative pressure dust suction device (air volume 30m 3 / h, filtration accuracy 0.3μm), with a semi-enclosed splash shield, the concentration of aluminum oxide powder is less than 1mg / m 3 , in compliance with OSHA PEL standards.
