The top of the mounting frame 9 is fixed with two fixed plates 303 by bolts, and a screw rod 302 is rotatably connected between the two fixed plates 303 through a bearing. A self-locking motor that drives the screw rod 302 to rotate along the axis is fixed to one side of one of the fixed plates 303 by bolts. By starting the self-locking motor, the output shaft of the self-locking motor drives the screw rod 302 to rotate, and the screw rod 302 drives the sliding The rack 8 slides left and right along the second slide rail 301, so that the burr removal device can deburr automobile pipe castings that do not exceed the length of the mounting rack 9, which greatly increases the scope of use of the device. One side of the two slides 8 is provided with a grinding component 1 for grinding the burrs on the end of the automobile pipe casting. One side of the two slides 8 and at the bottom of the grinding component 1 are provided with a receiving component 2 for collecting waste. The receiving component 2 includes two placing plates 202 fixed to one side of the slide 8 by bolts, and a receiving tray 201 is placed on the top of the two placing plates 202. A plurality of protrusions 204 are fixed to the bottom of the receiving tray 201 by bolts. A plurality of grooves 203 are provided on the top of the two placing plates 202 to cooperate with the protrusions 204 and correspond one to one. The waste materials polished out The receiving tray 201 is then taken out from the top of the placing plate 202, so that the waste in the receiving tray 201 can be easily removed. After the removal is completed, the receiving tray 201 is newly placed on the placing plate 202, and the protrusion 204 is inserted into the groove 203, thereby realizing the precise positioning of the receiving tray 201. A clamping assembly 4 for fixing the automobile pipe casting is provided at the top and center of the mounting frame 9. The clamping assembly 4 includes two frames 401 that are fixed to the top of the mounting frame 9 by bolts and are symmetrically placed. The inner sides of the two frames 401 are fixed with two telescopic rods 402 by bolts. The piston ends of the two telescopic rods 402 are fixed with a connecting frame 403 by bolts. One side of the connecting frame 403 is fixed by bolts There are two symmetrically arranged clamping blocks 404, and a driving assembly 6 is provided at the bottom of the mounting frame 9 for driving multiple connecting frames 403 to move inward at the same time. The driving assembly 6 includes a double-axis self-locking cylinder 604 fixed to the bottom of the mounting frame 9 by bolts, and the two piston ends of the double-axis self-locking cylinder 604 pass through the mounting frame 9 and are fixed to the fixing frame 603 by bolts. One side of the fixing frame 603 is provided with two inclined grooves 602 inclined from bottom to top and symmetrically arranged. A connecting rod 601 slidably connected to the inclined groove 602 is fixed between two adjacent connecting frames 403 by bolts. When the double-axis self-locking cylinder 604 is started, the piston end of the double-axis self-locking cylinder 604 drives the fixing frame 603 to move downward, and at the same time, the two inclined grooves 602 respectively push the two connecting rods 601 to move inward toward each other.At the same time, the connecting rod 601 slides along the inclined groove 602, and the two connecting rods 601 respectively drive the two connecting frames 403 to move inward, and the driving component 6 is started. The driving component 6 drives multiple connecting frames 403 to move inward, so that multiple clamping blocks 404 contact the outer wall of the automobile pipe casting at the same time, thereby fixing the automobile pipe casting. By using multiple clamping blocks 404 in conjunction with each other, automobile pipe castings with a diameter exceeding the diameter of the support plate 101 and not less than the distance between the upper and lower clamping blocks 404 can be clamped. The automobile pipe casting is fixed by the clamping assembly, and then the two moving components 3 are started. The two moving components 3 are respectively The two slides 8 are driven to move, so that the grinding assemblies 1 on one side of the two slides 8 contact the two ends of the automobile pipe casting respectively, and then the two grinding assemblies 1 are started. The two grinding assemblies 1 grind the two ends of the automobile pipe casting respectively. This solves the problem of having to process the two ends of the automobile pipe casting one by one during grinding. After completing the grinding work on one end, the polished pipe needs to be disassembled, turned around and reinstalled, and the other end needs to be polished and deburred. The deburring efficiency is greatly improved. The grinding waste will fall into the collection assembly, thereby preventing the waste from falling into the external space and causing the ground to be dirty.

[0042] In particular, in the present invention, the grinding assembly 1 includes a support plate 101 rotatably connected to one side of the slide 8 through a bearing, a first slide rail 102 is fixed to one side of the support plate 101 by bolts, and two sliders 103 are slidably connected to one side of the first slide rail 102 through a slide, and a grinding block 104 is provided on one side of the two sliders 103. A servo motor that drives the support plate 101 to rotate along the axis is fixed to one side of the slide 8 by bolts, and a quick-release assembly 7 is provided on one side of the slider 103 for facilitating the disassembly of the grinding block 104. The quick-release assembly 7 includes a screw thread welded on the support plate 101. The rod 704 on one side of the slider 103 and the grinding block 104 are provided with a slot 701 that cooperates with the rod 704. The inner wall of the slot 701 is provided with a notch 703. The outer wall of the rod 704 is adhered with an elastic rubber ring 702. With a little force, the grinding block 104 is pulled to make the slot 701 and the rod 704 fall off and plug. At the same time, the edge of the notch 703 squeezes the elastic rubber ring 702 to deform it, so that the elastic rubber ring 702 is separated from the notch 703, thereby greatly facilitating the replacement of the grinding block 104. One side of the support plate 101 is provided with a locking assembly 5 for fixing the two sliders 103. The locking assembly 5 includes two avoidance grooves 503 that are opened on one side of the support plate 101 and penetrate the support plate 101. One side of the two sliders 103 is provided with two symmetrically arranged threaded rods 502 that pass through the avoidance grooves 503. The outer sides of the multiple threaded rods 502 are all threadedly connected with a pressure block 501. When the pressure block 501 is rotated, the pressure block 501 moves inward along the threaded rod 502, so that the pressure block 501 contacts the support plate 101 and forms an extrusion state, thereby a friction The support plate 101 is fixed to prevent the grinding block 104 from shifting during use. The two sliders 103 are slid to adjust the positions of the two grinding blocks 104 so that the two grinding blocks 104 contact the inner ring edge and the outer ring edge of the automobile pipe casting respectively. The slider 103 is then fixed by the locking assembly 5. The servo motor is then started. The output shaft of the servo motor rotates with the support plate 101, and the support plate 101 drives the two grinding blocks 104 to rotate to grind and deburr the end of the automobile pipe casting.

[0043] In the present application, an annular groove is axially provided on the inner wall of the pressure block 501, and a nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial compression force generated by its elastic deformation forms an interference fit with a helix angle of 15°-20° with the surface of the threaded rod 502. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, thereby increasing the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing the loosening displacement caused by thread rebound.

[0044] The present invention is divided into the following steps when used:

[0045] S1: First, hold the automobile pipe casting and then activate the double-axis self-locking cylinder 604. The piston end of the double-axis self-locking cylinder 604 drives the fixing frame 603 to move downward. At the same time, the two inclined grooves 602 push the two connecting rods 601 to move inward toward each other. At the same time, the connecting rods 601 slide along the inclined grooves 602. The two connecting rods 601 drive the two connecting frames 403 to move inward, so that the multiple clamping blocks 404 contact the outer wall of the automobile pipe casting at the same time, thereby fixing the automobile pipe casting;

[0046] S2: Then start the two self-locking motors. The output shafts of the self-locking motors drive the screw 302 to rotate. The screw 302 drives the slide 8 to slide along the second slide rail 301, so that the two grinding blocks 104 move to the appropriate position.

[0047] S3: Then, the two sliders 103 are slid to adjust the positions of the two grinding blocks 104 so that the two grinding blocks 104 are in contact with the inner ring edge and the outer ring edge of the automobile pipe casting respectively;

[0048] S4: Then the pressing block 501 is rotated, and the pressing block 501 moves inward along the threaded rod 502, so that the pressing block 501 contacts the support plate 101 and forms an extrusion state, thereby fixing the support plate 101 through friction;

[0049] S5: Then, the two servo motors are started, and the output shafts of the two servo motors respectively drive the support plates 101 to rotate, and the two support plates 101 respectively drive the two grinding blocks 104 to rotate, so that the two ends of the automobile pipe casting are ground and deburred;

[0050] S6: At the same time, the waste residue produced by grinding will fall into the receiving tray 201, thereby preventing the waste from falling into the external space;

[0051] S7: After the grinding is completed, the two self-locking motors are started, and the output shafts of the self-locking motors drive the screw 302 to rotate, and the screw 302 drives the slide 8 to slide along the outside of the second slide rail 301, so that the two grinding blocks 104 are out of contact with the automobile pipe casting;

[0052] S8: Finally, the polished automobile pipe casting is taken out from the clamping assembly 4.

[0053] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
