Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field related to metal material processing, and more specifically, particularly relates to a grinding processing equipment for precision processing of metal materials. Background Art
[0002] Metal materials have many shapes, such as rings, cylinders and squares. In the production process of metal materials, the surface of the metal often has defects such as burrs, scratches, and sand holes left over from cutting or other processing. It is necessary to process them through grinding equipment. Generally, the metal material is ground by a grinding wheel, and becomes fine through friction, changing the surface roughness of the metal material. However, the grinding equipment for precision processing of metal materials in the prior art has the following defects:
[0003] In the prior art, when a grinding device for precision machining of metal materials is grinding the surface of a metal material, due to the high hardness of the metal material and the uneven surface of some metal materials, when the grinding wheel contacts the metal material, the metal material is prone to deviation, making it difficult to ensure the contact between the grinding wheel and the surface of the metal material, thereby affecting the grinding efficiency.
[0004] In the prior art, when grinding an annular metal part, a grinding device for precision machining of metal materials usually needs to grind the inner and outer sides of the annular metal part. However, after the inner side of the annular metal part is clamped and fixed and the outer side of the annular metal part is ground, the clamping assembly needs to be replaced or other clamping tools need to be used to clamp and fix the outer side of the annular metal part before the inner side of the annular metal part can be ground. In this process, the annular metal part needs to be repositioned, clamped and fixed, which is cumbersome and affects the grinding efficiency of the inner and outer sides of the annular metal part.
[0005] In the prior art, before grinding the inner side or outer side of an annular metal part, a grinding processing equipment for precision machining of metal materials usually needs to use two clamping assemblies to clamp and fix the inner side or outer side of the annular metal part respectively, and the two clamping assemblies are respectively located on the inner side and the outer side of the annular metal part; however, when grinding the inner side of the annular metal part, the clamping assembly located on the inner side of the annular metal part is likely to interfere with the movement of the grinding wheel, and when grinding the outer side of the annular metal part, the clamping assembly located on the outer side of the annular metal part is likely to interfere with the movement of the grinding wheel, causing the grinding wheel to contact the clamping assembly, thereby causing damage to the grinding wheel, affecting the efficiency and quality of the grinding processing of the inner and outer sides of the annular metal part.

[0050] Specific use of the present invention:
[0051] The staff places the annular metal part on the upper side of the processing table 15 and makes the annular metal part located between the two ends of the four U-shaped shells 32; the staff turns the two protective doors 11 to close the equipment body 10, and the staff can observe the processing conditions inside the equipment body 10 through the two windows 12.
[0052] When it is necessary to grind the inner side of the annular metal part, the staff controls the clamping assembly to start through the control panel 13, and the two small electric telescopic rods 28 extend to drive the annular part 58 to move upward. The annular part 58 moves upward to cooperate with the two first extrusion blocks 56, and the contact surfaces with the two second extrusion blocks 57 are inclined surfaces, so that the two clamping blocks 54 move in opposite directions, so that the two clamping blocks 54 can slide out of the corresponding two clamping grooves 48 respectively, so that the rotating plate 46 can rotate in the processing table 15; wherein, the two clamping blocks 54 move in opposite directions to compress the two springs 55 to generate elastic force.
[0053] Next, the small motor 31 is started to drive the rotating plate 46 to rotate counterclockwise. The rotating plate 46 rotates counterclockwise to make the lower parts of the four round rods 43 slide in an arc shape inside the four arc-shaped slide grooves 47 respectively. At this time, the lower parts of the four round rods 43 slide in an arc shape inside the four arc-shaped slide grooves 47 respectively, and the upper parts of the four round rods 43 move radially inside the four guide grooves 45 respectively, so that the four U-shaped shells 32 move radially inward at the same time; the radial inward movement of the four U-shaped shells 32 drives the four first clamping frames 33 and the first rubber blocks 35 to move. The outer side of the annular metal piece is squeezed and fixed; at this time, the outer side of the annular metal piece enters between the inner sides of the four first clamping frames 33, so that the upper and lower ends of the outer side of the annular metal piece are respectively in contact with the upper and lower end walls of the four first clamping frames 33, so that the annular metal piece is limited up and down by the four first clamping frames 33; and the sliding contact between two adjacent first rubber blocks 35 and the elasticity of the first rubber blocks 35 can clamp and fix the outer sides of the annular metal pieces with different outer diameters, so as to facilitate the grinding of the inner side of the annular metal piece.
[0054] At the same time, during the radial inner movement of the four U-shaped shells 32, the four first semicircular rods 41 always slide in contact with the middle upper side of the four pairs of guide blocks 44, so that the four first clamping frames 33 are always at the highest point, so as to clamp and fix the outer side of the annular metal piece; at the same time, the four second semicircular rods 42 slide in contact on the inclined surface of one end of the four pairs of guide blocks 44, so that the four second semicircular rods 42 and the four second fixing rods 38 move downward, and the four second fixing rods 38 move downward to drive the four second clamping frames 34 to move downward respectively, so as to avoid the four second clamping frames 34 affecting the grinding assembly to grind the inner side of the annular metal piece. Among them, the four second compression springs 40 are compressed to generate elastic force, so that under the elastic force of the four second compression springs 40, the four second semicircular rods 42 move downward and always slide in contact with the upper part of the inclined surface of one end of the four pairs of guide blocks 44, which is conducive to the four second clamping frames 34 entering one end of the four U-shaped shells 32 respectively, so as to facilitate the grinding of the inner side of the annular metal piece.
[0055] Then, the staff controls the two small electric telescopic rods 28 to contract and drive the annular member 58 to move downward through the control panel 13. The downward movement of the annular member 58 causes the two second extrusion blocks 57 to disengage from the two first extrusion blocks 56 respectively, thereby causing the two clamping blocks 54 to move in opposite directions under the elastic force of the two springs 55, causing the two clamping blocks 54 to enter the two clamping grooves 48 respectively, so that the two clamping blocks 54 cooperate with the two clamping grooves 48 to limit and fix the rotating plate 46, thereby limiting and fixing the clamping assembly, thereby preventing the clamping assembly from being displaced during the grinding process of the inner side of the annular metal part.
[0056] Secondly, the staff controls the grinding assembly to start through the control panel 13, and the first hydraulic telescopic rod 16 is extended and retracted to drive the first movable frame 17 to move horizontally on the guide rail 20, thereby adjusting the horizontal position of the grinding wheel 22; then the second hydraulic telescopic rod 18 is extended and retracted to drive the second movable frame 19 to move vertically, thereby adjusting the vertical position of the grinding wheel 22, so that the outer side of the grinding wheel 22 contacts the inner side of the annular metal part.
[0057] Finally, the staff controls the drive assembly to start through the control panel 13, and the second stepper motor 25 starts to drive the first ratchet 26 to rotate, and the outer side of the first ratchet 26 engages with the outer side of the second ratchet 27 to drive the rotating shaft 23 to rotate, and the rotation of the rotating shaft 23 drives the processing table 15 and the clamping assembly to rotate, and the rotation of the clamping assembly drives the annular metal part to rotate; at this time, the first stepper motor 21 starts to drive the grinding wheel 22 to rotate, and the rotation of the grinding wheel 22 cooperates with the rotation of the annular metal part and the outer side of the grinding wheel 22 contacts the inner side of the annular metal part, thereby grinding the inner side of the annular metal part.
[0058] When it is necessary to grind the outer side of the annular metal part, the staff controls the clamping assembly to start through the control panel 13, and the two small electric telescopic rods 28 extend to drive the annular part 58 to move upward. The annular part 58 moves upward to cooperate with the two first extrusion blocks 56 and the contact surfaces with the two second extrusion blocks 57 are inclined surfaces, so that the two clamping blocks 54 move in opposite directions, so that the two clamping blocks 54 can slide out of the corresponding two slots 48 respectively, so that the rotating plate 46 can rotate in the processing table 15.
[0059] Next, the small motor 31 is started to drive the rotating plate 46 to rotate clockwise. The rotating plate 46 rotates clockwise to make the lower parts of the four round rods 43 slide in an arc shape inside the four arc-shaped slide grooves 47 respectively. At this time, the lower parts of the four round rods 43 slide in an arc shape inside the four arc-shaped slide grooves 47 respectively, and the upper parts of the four round rods 43 move radially inside the four guide grooves 45 respectively, so that the four U-shaped shells 32 move radially outward at the same time; the radial outward movement of the four U-shaped shells 32 drives the four second clamping frames 34 and the plurality of second rubber blocks 36 to move to the annular metal part. The inner side is squeezed and contacted, thereby clamping and fixing the inner side of the annular metal part; at this time, the inner side of the annular metal part enters between the inner sides of the four second clamping frames 34, so that the upper and lower ends of the inner side of the annular metal part are respectively in contact with the upper and lower end walls of the four second clamping frames 34, thereby limiting the upper and lower positions of the annular metal part through the four second clamping frames 34; and the sliding contact between two adjacent second rubber blocks 36 and the elasticity of several second rubber blocks 36 can clamp and fix the inner sides of annular metal parts with different outer diameters, so as to facilitate the grinding of the outer sides of the annular metal parts.
[0060] At the same time, during the radial outer movement of the four U-shaped shells 32, the four second semicircular rods 42 always slide in contact with the upper middle side of the four pairs of guide blocks 44, so that the four second clamping frames 34 are always at the highest point, so as to clamp and fix the inner side of the annular metal piece; at the same time, the four first semicircular rods 41 slide in contact with the inclined surfaces at one end of the four pairs of guide blocks 44, so that the four first semicircular rods 41 and the four first fixing rods 37 move downward, and the four first fixing rods 37 move downward to drive the four first clamping frames 33 to move downward, so as to avoid the four first clamping frames 33 affecting the grinding process of the grinding assembly on the outer side of the annular metal piece. Among them, the four first compression springs 39 are compressed to generate elastic force, so that under the elastic force of the four first compression springs 39, the four first semicircular rods 41 move downward and always slide in contact with the inclined surfaces at one end of the four pairs of guide blocks 44, which is conducive to the four first clamping frames 33 entering one end of the four U-shaped shells 32 respectively, so as to facilitate the grinding process of the outer side of the annular metal piece.
[0061] Then, the staff controls the two small electric telescopic rods 28 to contract and drive the annular member 58 to move downward through the control panel 13. The downward movement of the annular member 58 causes the two second extrusion blocks 57 to disengage from the two first extrusion blocks 56 respectively, thereby causing the two clamping blocks 54 to move in opposite directions under the elastic force of the two springs 55, so that the two clamping blocks 54 enter the two clamping grooves 48 respectively, so that the rotating plate 46 can be limited and fixed by the cooperation of the two clamping blocks 54 and the two clamping grooves 48, thereby limiting and fixing the clamping assembly, and avoiding displacement of the clamping assembly during the grinding process of the outer side of the annular metal part.
[0062] Secondly, the staff controls the grinding assembly to start through the control panel 13, and the first hydraulic telescopic rod 16 is extended and retracted to drive the first movable frame 17 to move horizontally on the guide rail 20, thereby adjusting the horizontal position of the grinding wheel 22; then the second hydraulic telescopic rod 18 is extended and retracted to drive the second movable frame 19 to move vertically, thereby adjusting the vertical position of the grinding wheel 22, so that the outer side of the grinding wheel 22 contacts the outer side of the annular metal part.
[0063] Finally, the staff controls the drive assembly to start through the control panel 13, and the second stepper motor 25 starts to drive the first ratchet 26 to rotate, and the outer side of the first ratchet 26 engages with the outer side of the second ratchet 27 to drive the rotating shaft 23 to rotate, and the rotation of the rotating shaft 23 drives the processing table 15 and the clamping assembly to rotate, and the rotation of the clamping assembly drives the annular metal part to rotate; at this time, the first stepper motor 21 starts to drive the grinding wheel 22 to rotate, and the rotation of the grinding wheel 22 cooperates with the rotation of the annular metal part and the outer side of the grinding wheel 22 contacts the outer side of the annular metal part, thereby grinding the outer side of the annular metal part.
[0064] A grinding processing device for precision machining of metal materials of the present invention is provided with a clamping assembly, and the four U-shaped shells 32 in the clamping assembly are moved radially inwardly to drive the four first clamping frames 33 and a plurality of second rubber blocks 36 to move to squeeze and fix the outer side of the annular metal part; and the four second semicircular rods 42 are slidably contacted on the inclined surfaces of one ends of the four pairs of guide blocks 44 by the radial inward movement of the four U-shaped shells 32, so that the four second semicircular rods 42 and the four second fixing rods 38 move downward, and the four second fixing rods 38 move downward to drive the four second clamping frames 33 and the ... the four pairs of guide blocks 44, so that the four second semicircular rods 42 and the four second fixing rods 38 move downward, and the four second fixing rods 38 move downward to drive the four second clamping frames 33 and the plurality of second rubber blocks 36 to move to squeeze and fix the outer side of the annular metal part; and the four second semicircular rods 42 are slidably contacted on the inclined surfaces of the four pairs of guide blocks 44, and the four second semicircular rods 42 and the four second fixing rods The holding frame 34 moves downward to prevent the four second clamping frames 34 from affecting the grinding process of the inner side of the annular metal part by the grinding assembly; then the four U-shaped shells 32 move radially outward to drive the four second clamping frames 34 and the plurality of second rubber blocks 36 to move to squeeze and contact the inner side of the annular metal part, thereby clamping and fixing the inner side of the annular metal part; finally, the four first fixing rods 37 move downward to drive the four first clamping frames 33 to move downward respectively to prevent the four first clamping frames 33 from affecting the grinding process of the grinding assembly on the outer side of the annular metal part.
[0065] The present invention is a grinding processing equipment for precision machining of metal materials. The two clamping blocks 54 cooperate with the two clamping grooves 48 to limit and fix the rotating plate 46, thereby limiting and fixing the clamping assembly to prevent the clamping assembly from being displaced during the grinding process of the inner or outer side of the annular metal part; then the annular part 58 moves upward to cooperate with the two second extrusion blocks 57 to contact the inclined surfaces of the two first extrusion blocks 56 respectively, so that the two clamping blocks 54 move in opposite directions, so that the two clamping blocks 54 can slide out of the corresponding two clamping grooves 48, so that the rotating plate 46 can rotate in the processing table 15, so that the clamping assembly can be adjusted to clamp and fix annular metal parts of different specifications.
[0066] The grinding processing equipment for precision machining of metal materials of the present invention first moves radially inwardly through four first clamping frames 33, so that the upper and lower ends of the outer side of the annular metal part are respectively in contact with the upper and lower end walls of the four first clamping frames 33, so that the annular metal part is limited up and down through the four first clamping frames 33; then, through the sliding contact between two adjacent first rubber blocks 35 and the elasticity of several first rubber blocks 35, the outer side of the annular metal part with different outer diameters can be clamped and fixed, so as to facilitate the grinding processing of the inner side of the annular metal part; then, through the radial outward movement of four second clamping frames 34, the inner side of the annular metal part is located between the four second clamping frames 34, so as to facilitate the upper and lower limit of the inner side of the annular metal part through the four second clamping frames 34; finally, through the sliding contact between two adjacent second rubber blocks 36 and the elasticity of several second rubber blocks 36, the inner side of the annular metal part with different inner diameters can be clamped and fixed, so as to facilitate the grinding processing of the outer side of the annular metal part.
