Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of grinding devices, in particular to an inner wall grinding device for high-purity materials. Background Art
[0002] High-purity materials refer to materials that contain very little or almost no impurities. Such materials usually have high purity and uniformity, making them widely used in scientific research, industrial production and other fields.
[0003] Crucible is a container for carrying and heating substances, usually used in high-temperature experiments or processes such as smelting metals, ores, and glass. In order to ensure its stability and reliability in high-temperature environments, most crucibles are made of high-purity materials. The inner walls of various types of crucibles made of high-purity materials often need to undergo an inner wall grinding process after demolding to remove protrusions and inner wall burrs and make the inner wall smooth and flat.
[0004] CN202111140176.3 discloses a device for grinding the inner wall of the socket of a transfer pipe in a water conservancy project, comprising a workbench, a support leg fixedly installed at the bottom of the workbench, a clamping seat fixedly installed on one side of the surface of the workbench, and a grinding mechanism fixedly installed on the other side, a dust suction hole is opened in the middle of the workbench, a supporting mechanism is provided on the side of the dust suction hole close to the clamping seat, and a cutting mechanism is provided on the rear side of the dust suction hole.
[0005] The above technical solution is recorded in paragraph 0038 of the specification that "the transfer tube to be ground passes through the hollow shaft, the second screw is rotated to rotate the third screw, and the third slider is matched with the third screw thread. When the third screw rotates, the third slider moves along the third screw, so that the clamping block fixed on the third slider moves in the circular direction of the clamping ring, and the outer wall of the transfer tube is tightened and fixed." However, high-purity material is a fragile material, which can be easily damaged during the tightening process, resulting in increased production costs and reduced qualified rates. Moreover, after the inner wall of the transfer tube is ground, the device does not have an auxiliary structure to clean the dust on the inner wall of the transfer tube, so dust will easily remain on the inner wall of the transfer tube.

[0022] 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.
[0023] Example 1
[0024] refer to Figure 1 and Figure 2 A device for grinding the inner wall of a high-purity material comprises a frame 1, a carrier 2 and a flexible material 3. The frame 1 is provided with a fixed seat 11 and a grinding module 12. The fixed seat 11 is provided with a rotating mechanism 111 for driving the carrier 2 to rotate. The carrier 2 can be detachably mounted on the rotating mechanism 111. The carrier 2 is a hollow structure. The flexible material 3 is filled in the gap between the outer wall of the high-purity material and the inner wall of the carrier 2. The frame 1 is also provided with a dust removal mechanism 13 for collecting dust generated by grinding the inner wall of the high-purity material. The input end of the dust removal mechanism 13 is located in the rotating mechanism 111. The grinding module 12 is used for grinding the inner wall of the high-purity material.
[0025] Under this design, the technicians in this field first install the carrier 2 on the rotating mechanism 111, then put the high-purity material into the carrier 2, and fill the gap between the outer wall of the high-purity material and the inner wall of the carrier 2 with the flexible material 3, so that the flexible material 3 will be close to the outer wall of the high-purity material, and then start the rotating mechanism 111 to drive the carrier 2 to rotate, and cooperate with the grinding module 12 to grind the inner wall of the high-purity material. The dust generated during the grinding process will first enter the input end of the dust removal mechanism 13, and the dust will be collected by the dust removal mechanism 13; by placing the high-purity material into the carrier 2 for protection, damage to the high-purity material is avoided when it is fixed, and at the same time, the gap between the outer wall of the high-purity material and the inner wall of the carrier 2 is filled with the flexible material 3, which can not only play a buffering role during grinding, but also prevent the carrier 2 from scratching the surface of the high-purity material, and a dust removal mechanism 13 is set on the frame 1 to clean the inner wall of the high-purity material to prevent dust from remaining on the inner wall of the high-purity material.
[0026] Preferably, the polishing module 12 includes a polishing mechanism 121 for polishing the inner wall of the high-purity material, and a moving unit 122 for driving the polishing mechanism 121 to move forward and backward, left and right, or up and down. The moving unit 122 is connected to the frame 1, and the polishing mechanism 121 is connected to the moving unit 122.
[0027] Specifically, during grinding, the mobile unit 122 first drives the grinding mechanism 121 to move left and right or up and down to a suitable position that can contact the inner wall of the high-purity material. At the same time, the rotating mechanism 111 drives the carrier 2 to rotate, and under the drive of the mobile unit 122, the grinding mechanism 121 moves deep into the high-purity material to complete the grinding inside the high-purity material. After completing the grinding of the inner wall of the high-purity material, the mobile unit 122 will drive the grinding mechanism 121 to reset.
[0028] More preferably, the mobile unit 122 includes a feeding mechanism 1221 connected to the frame, a positioning mechanism 1222 connected to the feeding mechanism 1221, the grinding mechanism 121 is connected to the positioning mechanism 1222, the feeding mechanism 1221 is used to drive the grinding mechanism 121 to move forward and backward, and the positioning mechanism 1222 is used to drive the grinding mechanism 121 to move left and right or up and down.
[0029] Furthermore, when grinding is required, the positioning mechanism 1222 first drives the grinding mechanism 121 to move left and right or up and down to a suitable position, so that when the feeding mechanism 1221 drives the grinding mechanism to move deeper into the high-purity material, the grinding mechanism 121 can contact the inner wall of the high-purity material. After reaching the suitable position, the feeding mechanism 1221 drives the grinding mechanism 121 to move to the initial position for grinding, and at the same time the rotating mechanism 111 drives the rotation of the carrier 2, and then the positioning mechanism 1222 is switched to the torque mode, and the feeding motor drives the grinding mechanism 121 again, so that the grinding mechanism 121 gradually moves deeper into the high-purity material to complete the grinding of the inner wall of the high-purity material. After grinding is completed, the positioning mechanism 1222 first drives the grinding mechanism 121 to leave the inner wall of the high-purity material, and then the feeding mechanism 1221 drives the grinding mechanism 121 to reset, and finally the positioning mechanism 1222 drives the grinding mechanism 121 to reset.
[0030] In this embodiment, a torque sensor 4 is disposed between the grinding mechanism 121 and the positioning mechanism 1222 .
[0031] Specifically, the torque sensor 4 can provide real-time feedback of the grinding torque. When the torque sensor 4 detects that the grinding torque value is too low, the positioning mechanism 1222 will drive the grinding mechanism 121 to move closer to the inner wall of the high-purity material, thereby increasing the contact area between the grinding mechanism 121 and the inner wall of the carrier 2. When the torque sensor 4 detects that the grinding torque value is too high, the positioning mechanism 1222 will drive the grinding mechanism 121 away from the inner wall of the high-purity material, thereby reducing the contact area between the grinding mechanism 121 and the inner wall of the high-purity material.
[0032] Preferably, the rotating mechanism 111 includes a rotating motor 1113 connected to the fixed seat 11, a chuck 1111 rotatably connected to the fixed seat 11, and a belt 1112 sleeved on one end of the chuck 1111 and the power output end of the rotating motor 1113. The chuck 1111 is used to clamp the carrier 2. The rotating motor 1113 drives the chuck 1111 to rotate through the belt 1112. The input end of the dust removal mechanism 13 is located in the chuck 1111.
[0033] Furthermore, the rotating motor 1113 drives the belt 1112 to rotate and thereby drives the chuck 1111 to move, so that the carrier 2 clamped on the chuck 1111 can rotate, so that the grinding module 12 can grind the inner wall of the high-purity material more efficiently and evenly, and the input end of the dust removal mechanism 13 is located in the chuck 1111, so that the dust removal mechanism 13 can collect the dust remaining on the inner wall of the high-purity material.
[0034] More preferably, the chuck 1111 is a four-jaw chuck. The four-jaw chuck has a strong clamping force and can be applied to irregular workpieces.
[0035] In this embodiment, the dust removal mechanism 13 includes a dust removal pipe 131 and an exhaust system 132. The output end of the dust removal pipe 131 is connected to the exhaust system 132, and the input end of the dust removal pipe 131 is located in the chuck 1111; the exhaust system 132 includes a filter assembly 1321 installed at the output end of the dust removal pipe 131, an air outlet pipe 1322 connected to the filter assembly 1321, and an exhaust fan 1323 located in the air outlet pipe 1322.
[0036] Furthermore, in the process of the grinding module 12 continuously grinding the inner wall of the high-purity material, the generated dust will first enter the input end of the dust removal pipe 131 under the action of the exhaust fan 1323, and then move along the pipeline direction of the dust removal pipe 131, and finally be filtered by the filter component 1321 to prevent the generated dust from being discharged from the outlet pipe 1322.
[0037] In actual application, a dust removal plate 14 is also provided on the frame 1, and the dust removal plate 14 is located on one side of the fixed seat 11. A chamber is provided in the dust removal plate 14, and a plurality of through holes 141 are provided on the side of the dust removal plate 14 close to the fixed seat 11. The plurality of through holes 141 are all connected to the chamber, and the chamber is connected to an external negative pressure device.
[0038] Specifically, a dust removal plate 14 is provided on the frame 1 to connect the chamber of the dust removal plate 14 to an external negative pressure device, so that the dust generated during grinding will be sucked into the chamber through the through hole 141 of the dust removal plate 14, and the dust will be further collected by the dust removal plate 14 to prevent the dust from floating in the working environment.
[0039] Preferably, the flexible material 3 is rubber foam. Rubber foam has good buffering performance, can effectively absorb impact force, and protect high-purity materials from damage.
[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements or modifications without departing from the principle of the present invention. These improvements or modifications should also be regarded as within the protection scope of the present invention.
