Description

Technical Field

[0001] The utility model belongs to the technical field of crucible grinding, and specifically relates to a crucible grinding device with a dust removal structure. Background Art

[0002] The crucible of the prior art is a cup-shaped vessel used in laboratories for high-temperature heating of solids. There are many model specifications of crucibles, which are not restricted by production scale, batch size, and types of smelting substances during application. They can be arbitrarily selected, have strong applicability, and can ensure the purity of the smelted substances. When the crucible is used for a long time, the quartz crucible is prone to stains and scratches, which not only affect the experimental results but also accelerate the wear of the quartz crucible and reduce its service life. Therefore, a grinding device is needed to regularly grind the quartz crucible, which can not only protect the experimental instruments but also improve the experimental accuracy.

[0003] Chinese Patent with application number CN202323001188.5 discloses a high-efficiency crucible grinding device, including a bottom plate and several groups of guide columns installed on the bottom plate. The top of the guide columns is installed with a top plate. The top of the top plate is installed with a hydraulic cylinder. The movable end of the hydraulic cylinder is installed with a movable plate, and the movable plate slides on the guide columns. The top of the bottom plate is installed with a template for positioning the crucible. The crucible needs to be placed in the template, and then the movable plate is pushed up and down by the hydraulic cylinder, so that the grinding roller can contact the inner wall of the crucible. With the cooperation of the motor driving the main gear to rotate, under the cooperation of multiple main gears and internal gear rings, multiple grinding rollers rotate and rotate around the connecting shaft, so the grinding effect is better. In addition, the grinding disc can grind the bottom end of the inner wall of the crucible, so the grinding is fast and convenient.

[0004] The above technical solution can achieve grinding of the inner wall and bottom of the crucible container, improving the convenience of grinding. However, when using the crucible, crucibles of different diameters may be used simultaneously.

Detailed implementation manners

[0031] Now, the present utility model will be further described in detail with reference to the accompanying drawings.

[0032] Please refer to Figures 1-5 As shown, in this embodiment, a crucible grinding device with a dust removal structure is provided, including a placing block 1. The upper side of the placing block 1 is fixedly connected to a U-shaped frame 2. The upper side of the inner wall of the U-shaped frame 2 is provided with a hydraulic cylinder 3. The output end of the hydraulic cylinder 3 is fixedly connected to a linkage plate 4. The lower side of the linkage plate 4 is fixedly connected with a grinding motor 5. The output end of the grinding motor 5 is fixedly connected with a T-shaped plate 6. Two extension grooves 7 are opened on the lower side of the T-shaped plate 6. A driving mechanism 8 is installed on the lower side of the T-shaped plate 6 and between the two extension grooves 7;

[0033] Adjusting plates 9 are slidably fitted to the inner walls of the two extension grooves 7. Edge grinding plates 10 are fixedly connected to the opposite sides of the two adjusting plates 9. A first grinding strip 11 is fixedly connected to the lower sides of the two adjusting plates 9 and one side of the edge grinding plates 10. Two second grinding strips 12 are fixedly connected to the lower side of the T-shaped plate 6;

[0034] Reinforcement mechanisms 13 are respectively installed between the T-shaped plate 6 and the edge grinding plates 10. A dust suction mechanism 14 is installed inside the placing block 1.

[0035] One application of this embodiment is as follows: during use, first place the crucible to be polished on the placement net 142. Then, through the multiple dust suction mechanisms 14, the clamping blocks 17 are pushed to move, so as to fix the crucible. Next, start the polishing motor 5 to rotate, driving the T-shaped plate 6 to rotate rapidly. During the rotation, the first polishing strip 11 and the second polishing strip 12 rapidly flip around the T-shaped plate 6. Then, start the hydraulic cylinder 3 to push the linkage plate 4 downward, so that it enters the crucible. The first polishing strip 11 and the second polishing strip 12 rapidly rotate and contact the inside of the crucible to achieve polishing.

[0036] When polishing different crucibles, first, the hollow block 131 and the extension block 132 can be separated by operating the reinforcement mechanism 13. Then, by operating the driving mechanism 8, the two adjustment plates 9 are moved, so as to change the overall width diameter of the T-shaped plate 6. Then, fix the reinforcement mechanism 13 to improve the stability effect. During the movement, the first polishing strip 11 and the second polishing strip 12 expand, realizing an increase in the polishing diameter, and thus facilitating the polishing of crucibles with different diameters, improving the applicable range. The bidirectional lead screw 802 is a high-precision lead screw, and the positioning accuracy can reach 0.01 mm - 0.02 mm.

[0037] By setting the adjustment plates 9, it can be realized that the two adjustment plates 9 are expanded from the extension slots 7 through the reinforcement mechanism 13, driving the first polishing strip 11 and the second polishing strip 12 to expand relative to each other, realizing the adjustment of the overall polishing diameter, and thus facilitating the polishing of crucibles with different diameters, improving the applicable range of processing and polishing.

[0038] The driving mechanism 8 of this embodiment includes a driving groove 801 opened on the lower side of the inner wall of the T-shaped plate 6, a bidirectional lead screw 802 rotatably fitted on the inner wall of the driving groove 801 and threadedly fitted with the two adjustment plates 9, a worm gear 803 fixedly connected to the bidirectional lead screw 802, and a worm 804 rotatably fitted on one side of the driving groove 801 and meshed with the worm gear 803.

[0043] The suction fan 145 sucks air into the interior of the storage frame 143 through the dust filtering cloth 144, creating a negative pressure inside the storage frame 143. The gas needs to enter a large amount of air through the placement net 142 from the upper side of the dust extraction port 141, so that during the grinding process, the floating dust that may be generated is adsorbed to avoid dust pollution of the environment and inhalation by personnel, which affects physical health.

[0044] A dust collecting hood 15 is fixedly connected to the upper side of the placement block 1 in this embodiment. A plurality of clamping cylinders 16 are installed on the inner wall of the dust collecting hood 15. The output ends of the plurality of clamping cylinders 16 are all fixedly connected with clamping blocks 17. After the crucible is placed, the crucible is fixed by respectively starting the plurality of clamping cylinders 16 to press the clamping blocks 17 to avoid the crucible shaking during the grinding process.

[0045] On both sides of the inner walls of the two extension slots 7 in this embodiment, guiding slots 18 are opened. The inner walls of the plurality of guiding slots 18 are all slidably fitted with guiding blocks 19 fixedly connected to the two adjusting plates 9. By the guiding blocks 19 moving in the guiding slots 18, the stability of the adjusting plates 9 is further improved during the rotation of the adjusting plates 9.
