Description

Technical Field

However, the striking block production in the prior art has the following defects: In the prior art, there are annular grooves and through holes on the striking block. When the striking block is subjected to surface treatment, the outer wall of the striking block, the inner wall of the through hole and the annular groove need to be polished. The current processing equipment used for the production of striking blocks can usually only polish the outer wall of the striking block and the inner wall of the through hole, and it is difficult to polish the annular groove of the striking block, thereby affecting the surface treatment efficiency of the striking block.

[0034] Preferably, see Attachment Figure 3 , Attachment Figure 4 , Attachment Fig.12 , Attachment Fig.14 , Attachment Fig.15 The clamping assembly includes an operating table 46, which is fixed on the upper side of the workbench 10. Two arc-shaped clamping blocks 47 are symmetrically slidably provided on the upper side of the operating table 46. A rubber piece 48 is provided on each side of the two arc-shaped clamping blocks 47 close to each other. A positioning groove 28 for limiting the striking block workpiece 57 is provided in the middle of the upper part of the operating table 46.

[0035] Preferably, see Attachment Figure 3 , Attachment Figure 4 , Attachment Fig.12 , Attachment Fig.14 , Attachment Fig.15 Two slide grooves 49 are symmetrically arranged on the upper part of the operating table 46 , and a slide rod 52 is fixedly arranged on the lower side of the two arc-shaped clamping blocks 47 , respectively. The two slide rods 52 slide radially in the two slide grooves 49 , respectively.

[0036] Preferably, see Attachment Figure 3 , Attachment Figure 4 , Attachment Fig.12 , Attachment Fig.14 , Attachment Fig.15 A second stepper motor 53 is provided on the upper inner side of the workbench 10, and a rotating plate 50 is provided at the output end of the second stepper motor 53. Two arc-shaped slide grooves 51 are symmetrically provided on the rotating plate 50. The rotating plate 50 rotates in the operating table 46, and the lower ends of the two slide rods 52 slide in an arc shape in the two arc-shaped slide grooves 51 respectively.

[0037] Specific use of the present invention: The staff member places the striking block workpiece 57 in the positioning groove 28 so that the annular groove 58 in the striking block workpiece 57 opens upward. At this time, the control system controls the second stepper motor 53 to start, and the second stepper motor 53 starts to drive the rotating plate 50 to rotate forward. The rotating plate 50 rotates forward to drive the two arc-shaped slide grooves 51 to rotate, so that one end of the two slide rods 52 slides in an arc shape in the two arc-shaped slide grooves 51, so that the other ends of the two slide rods 52 move radially inward in the two slide grooves 49. The radial inward movement of the two slide rods 52 drives the two arc-shaped clamping blocks 47 and the rubber member 48 to approach each other, and the two rubber members 48 approach each other to clamp and fix the lower outer wall of the striking block workpiece 57.

[0038] Secondly, the control system controls the hydraulic telescopic rod 13 to extend and drive the first movable plate 14 and the circular plate 15 to move downward, and the circular plate 15 moves downward and drives the processing member 18 to move downward, so that the upper end of the outer wall of the striking block workpiece 57 enters into the first U-shaped frames 22, and the upper end of the inner wall of the through hole 59 in the striking block workpiece 57 enters into the second U-shaped frames 23. When the annular grinding member 21 contacts the inner lower side of the annular groove 58, the hydraulic telescopic rod 13 stops. Among them, the first movable plate 14 moves downward and drives the second movable plate 54 to move downward, and the second movable plate 54 moves downward and drives the two pairs of guide blocks 55 to slide on the two guide rails 56 respectively, so that the processing member 18 moves downward smoothly.

[0039] Next, the control system controls the electric telescopic rod 17 to extend, and the extension of the electric telescopic rod 17 drives the second ring 41 to move downward, and the second ring 41 moves downward to drive the connecting block 42 and the first ring 40 to move downward. The second ring 41 moves downward to push the first push rods 43 and the first U-shaped frame 22 to move downward, and the first U-shaped frame 22 moves downward to drive the two first push rods 33. The ends of the two first push rods 33 that are away from each other are respectively in sliding contact with the inclined surfaces of one side of the two first guide members 32, and the two first push rods 33 move downward and are guided by the two first guide members 32, so that the two first push rods 33 approach each other. The two first push rods 33 approach each other and drive the two first L-shaped grinding members 30 to approach each other. The two first L-shaped grinding members 30 approach each other and contact the outer wall of the striking block workpiece 57 and the outer wall of the annular groove 58, so that the outer wall of the striking block workpiece 57 and the outer wall of the annular groove 58 can be rotated and ground by using the first L-shaped grinding members 30. The two first L-shaped polishing members 30 approach each other to stretch the two third springs 26 to generate elastic force, and under the action of the elastic force of the two third springs 26, the two first L-shaped polishing members 30 can be moved away from each other and reset. The first U-shaped frame 22 moves downward in the first annular groove 19 to stretch the first spring 24 to generate elastic force.

[0040] At the same time, the first ring 40 moves downward to push the second push rods 44 and the second U-shaped frame 23 downward, and the second U-shaped frame 23 moves downward to drive the two second push rods 37 downward. The two second push rods 37 move downward because the ends of the two second push rods 37 that are away from each other are in sliding contact with the inclined surfaces of one side of the two second guide members 36, and the two second push rods 37 move downward and are guided by the two second guide members 36, so that the two second push rods 37 are close to each other. The two second push rods 37 approach each other and drive the two second L-shaped grinding pieces 34 to approach each other. The two second L-shaped grinding pieces 34 approach each other and contact the inner wall of the through hole 59 and the inner side wall of the annular groove 58 respectively, so that the inner wall of the through hole 59 and the inner side wall of the annular groove 58 can be rotated and ground by several pairs of second L-shaped grinding pieces 34, so as to fully grind the surface of the striking block workpiece 57, and the positions of several pairs of first L-shaped grinding pieces 30 and several pairs of second L-shaped grinding pieces 34 can be adjusted according to the size of the striking block workpiece 57, so as to improve the processing efficiency of the striking block workpiece 57. Among them, the two second L-shaped grinding pieces 34 approach each other and respectively stretch the two fourth springs 27 to generate elastic force. Under the elastic force of the two fourth springs 27, the two second L-shaped grinding pieces 34 can be reset away from each other. The second U-shaped frame 23 moves downward to stretch the second spring 25 to generate elastic force.

[0041] Then, the control system controls the first stepper motor 16 to start, and the first stepper motor 16 starts to drive the processing member 18 to rotate. The processing member 18 rotates to drive the first L-shaped grinding members 30 and the second L-shaped grinding members 34 to rotate, so as to perform a rotational grinding effect on the surface of the striking block workpiece 57. The processing member 18 rotates to drive the first push rods 43 to rotate. Through the upper end of the first push rod 43 and the outer sliding contact of the second protrusions 39, the first push rod 43 rotates under the guidance of the second protrusions 39, so that the first push rod 43 and the first U-shaped frame 22 move downward slightly. The downward movement of the first U-shaped frame 22 stretches the first spring 24 to generate elastic force. When the upper end of the first push rod 43 is out of contact with the second protrusion 39, under the elastic force of the first spring 24, the connecting block 42 and the first U-shaped frame 22 move upward slightly, so that under the guidance of the second protrusions 39 and the elastic force of the first spring 24, the connecting block 42 and the first U-shaped frame 22 can move up and down slightly. The small up and down movement of the first U-shaped frame 22 drives the two first L-shaped grinding pieces 30 to move up and down slightly. Several pairs of first L-shaped grinding pieces 30 move up and down slightly and rotate, thereby improving the effect of grinding the outer wall of the striking block workpiece 57 and the outer side wall of the annular groove 58.

[0042] At the same time, the processing member 18 rotates to drive the second push rods 44 to rotate. The upper ends of the second push rods 44 are in sliding contact with the outside of the first protrusions 38. The first push rods 43 rotate and are guided by the first protrusions 38, so that the second push rods 44 and the second U-shaped frame 23 move downward slightly. The downward movement of the second U-shaped frame 23 stretches the second spring 25 to generate elastic force. When the upper ends of the second push rods 44 are out of contact with the first protrusions 38, the second push rods 44 and the second U-shaped frame 23 move upward slightly under the elastic force of the second spring 25. So that under the guidance of the first protrusions 38 and the elastic force of the second spring 25, the second push rods 44 and the second U-shaped frame 23 can move up and down slightly. The small up and down movement of the second U-shaped frame 23 drives the two second L-shaped grinding pieces 34 to move up and down slightly. Several pairs of second L-shaped grinding pieces 34 move up and down slightly and rotate, thereby improving the rotational grinding effect on the inner wall of the through hole 59 and the inner side wall of the annular groove 58, thereby improving the efficiency of processing the striking block workpiece 57.

[0043] Finally, the processing member 18 rotates to drive the annular grinding member 21 to rotate, and the annular grinding member 21 rotates to perform a grinding process on the inner lower side of the annular groove 58 .

[0044] The processing device for producing the striking block of the present invention is provided with the second circular ring 41, the first push rod 43, the first U-shaped frame 22, the first L-shaped grinding piece 30, the first guide piece 32, and the first push rod 33. The second circular ring 41 moves downward to push the first push rods 43 and the first U-shaped frame 22 to move downward, and the first U-shaped frame 22 moves downward to drive the two first push rods 33. The ends of the two first push rods 33 that are away from each other are respectively in sliding contact with the inclined surfaces of one side of the two first guide pieces 32, and the two first push rods 33 move downward to be guided by the two first guide pieces 32, so that the two first push rods 33 approach each other. The two first push rods 33 approach each other to drive the two first L-shaped grinding pieces 30 to approach each other, and the two first L-shaped grinding pieces 30 approach each other to contact the outer wall of the striking block workpiece 57 and the outer side wall of the annular groove 58, so that the outer wall of the striking block workpiece 57 and the outer side wall of the annular groove 58 can be subjected to rotational grinding. Then, through the arrangement of the first circular ring 40, the second push rod 44, the second U-shaped frame 23, the second L-shaped grinding piece 34, the second groove 35, and the second guide 36, the first circular ring 40 moves downward to push the second push rods 44 and the second U-shaped frame 23 downward, and the second U-shaped frame 23 moves downward to drive the two second push rods 37 downward. The two ends of the two second push rods 37 that are away from each other are respectively in sliding contact with the inclined surfaces of one side of the two second guides 36, and the two second push rods 37 move downward and are guided by the two second guides 36, so that the two second push rods 37 are close to each other. The two second push rods 37 approach each other, driving the two second L-shaped grinding members 34 to approach each other. The two second L-shaped grinding members 34 approach each other and contact the inner wall of the through hole 59 and the inner side wall of the annular groove 58 respectively, so that the inner wall of the through hole 59 and the inner side wall of the annular groove 58 can be rotationally ground by several pairs of second L-shaped grinding members 34, so that the surface of the striking block workpiece 57 can be comprehensively ground, and the positions of several pairs of first L-shaped grinding members 30 and several pairs of second L-shaped grinding members 34 can be adjusted according to the size of the striking block workpiece 57 to improve the efficiency of processing the striking block workpiece 57.

[0045] The processing device for producing the striking block of the present invention can make the connecting block 42 and the first U-shaped frame 22 move up and down slightly by setting the second protrusion 39 and the first spring 24 under the guiding action of the second protrusions 39 and the elastic force of the first spring 24. The small up and down movement of the first U-shaped frame 22 drives the two first L-shaped grinding pieces 30 to move up and down slightly, and the several pairs of first L-shaped grinding pieces 30 move up and down slightly and rotate, thereby improving the effect of grinding the outer wall of the striking block workpiece 57 and the outer side wall of the annular groove 58. Furthermore, by setting the second spring 25 and the first protrusion 38, under the guiding action of the first protrusions 38 and the elastic force of the second spring 25, the second push rod 44 and the second U-shaped frame 23 can move up and down slightly. The small up and down movement of the second U-shaped frame 23 drives the two second L-shaped grinding pieces 34 to move up and down slightly. Several pairs of second L-shaped grinding pieces 34 move up and down slightly and rotate, thereby improving the rotational grinding effect on the inner wall of the through hole 59 and the inner side wall of the annular groove 58, thereby improving the processing effect of the striking block workpiece 57.
