Description

Technical Field

[0001] The invention relates to the technical field of polishing processing, in particular to a casting polishing device with a powder collecting function. Background Art

[0002] Polishing is a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. When parts are cast, burrs and unevenness usually appear on their surfaces, and polishing is required to improve the surface quality of the parts.

[0003] The patent publication number is CN115157094A, which is a device for polishing the inner wall of a casting pipe fitting. Its structure mainly includes a base, a processing table and a frame. A polishing mechanism for polishing the inner wall of the pipe fitting is arranged on the frame, a transmission mechanism is arranged on the base, and a plurality of positioning mechanisms are evenly arranged along the circumferential direction of the processing table. When polishing, the pipe fitting is placed in the positioning mechanism on the processing table, and the processing table drives the pipe fitting to move through the transmission mechanism, so that the pipe fitting can be transferred to the polishing mechanism for inner wall polishing.

[0004] However, the grinding function of the above-mentioned equipment is relatively simple, and it can only grind the inner wall of the pipe fitting, and the pipe fitting is located inside the positioning mechanism, that is, the outer wall of the pipe fitting will be restricted by the positioning mechanism. Therefore, it is not convenient to add an outer wall grinding structure to the device, resulting in incomplete grinding of the pipe fitting. When the outer wall needs to be polished, the pipe fitting needs to be unloaded, transferred, and repositioned, which makes the pipe fitting grinding operation inconvenient.

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0047] Embodiment 1, please refer to the attached drawings, the present invention provides a technical solution:

[0048] A casting polishing device with a powder collection function, such as Figure 1 As shown, it includes a workbench 100, in which a material transfer mechanism and a first grinding assembly are provided, and a material collecting trough 102 is provided at the bottom of the workbench 100;

[0049] An arc groove 101 is provided in the middle of the workbench 100, a material collecting trough 102 is fixed in the middle of the bottom of the arc groove 101, and a material transfer mechanism and a first grinding assembly are located in the arc groove 101. Figure 7 As shown, an air outlet is provided on the side wall of the collecting trough 102, a dust filter 104 is provided on the inner side of the air outlet, and a suction fan 105 is provided on the outer side of the air outlet;

[0050] The material transfer mechanism includes support plates 301 symmetrically fixed on both sides of the top of the arc-shaped groove 101, a cylindrical barrel 300 is fixed between the two support plates 301, and two rotating components are symmetrically arranged on the two side sections of the cylindrical barrel 300. The rotating components are connected to the support plates 301 on the corresponding side by moving the hydraulic telescopic rod 401. Four positioning components 500 are evenly arranged on each rotating component along the circumferential direction, and an adjustment component is arranged between the two rotating components.

[0051] The first grinding assembly includes two arc plates 200 symmetrically arranged in the arc groove 101, the bottom of the arc plates 200 is fixed to the bottom surface of the arc groove 101 by a plurality of evenly arranged fixing rods 201, and an arc-shaped grinding plate 202 is arranged on the top of one of the arc plates 200, and an arc-shaped cleaning plate 203 is arranged on the top of the other arc plate 200, and bristles are evenly distributed on the cleaning plate 203;

[0052] A vertical plate 204 is fixed to the bottom of the adjacent ends of the two arc plates 200 , a clamping assembly is arranged between the two vertical plates 204 , a fixing cylinder 103 is arranged at the position of the clamping assembly at the lower part of the side wall of the arc groove 101 , and a second grinding assembly is arranged in the fixing cylinder 103 .

[0053] When grinding the cast pipe, the pipe fitting is loaded and positioned at the left side of the cylindrical barrel 300, and then the pipe fitting is rotated downward along the arc groove 101 to the lower position of the cylindrical barrel 300, and during the rotation, it contacts the arc-shaped grinding plate 202 to complete the grinding of the outer wall of the pipe fitting; when the pipe fitting is located at the lower position of the cylindrical barrel 300, the pipe fitting is positioned and switched and internally ground, and then the pipe fitting is rotated to the right along the arc groove 101, and at the same time contacts and cleans the arc-shaped cleaning plate 203, and finally the pipe fitting moves to the right side of the cylindrical barrel 300 for unloading; therefore, when the pipe fitting moves from the left side of the cylindrical barrel 300 to the lower position of the cylindrical barrel 300 and then to the right side of the cylindrical barrel 300, the equipment sequentially performs loading, outer wall grinding, inner wall grinding, cleaning and unloading to realize multi-station processing.

[0054] Among them, when the pipe is loaded, the pipe is transported to between the two positioning components 500 on the left side of the cylindrical barrel 300 through an external loading device, and then the position of the positioning component 500 relative to the cylindrical barrel 300 is adjusted by the adjustment component, that is, the rotation radius of the subsequent pipe when it rotates along the outer side of the cylindrical barrel 300 is adjusted to ensure that the pipe can maintain contact with the grinding plate 202 when it moves along the arc groove 101. At the same time, the position of the rotating components on both sides on the cylindrical barrel 300 is adjusted by moving the hydraulic telescopic rod 401, so as to adjust the spacing between the positioning components 500 on both sides to make it adapt to the length of the pipe, so that the positioning component 500 can be located on the inner side of the end of the pipe under the position adjustment action of the adjustment component and the moving hydraulic telescopic rod 401, and the end of the pipe is limited by the internal structure of the positioning component 500.

[0055] When the pipe rotates, the rotating assembly is started to drive the positioning assembly 500 and the pipe to rotate. During the rotation process, the outer wall of the pipe contacts the grinding plate 202, and the positioning assembly 500 drives the pipe to rotate, so that the pipe contacts the grinding plate 202 and rotates at the same time, thereby grinding the outer wall of the pipe through the grinding plate 202.

[0056] When grinding the inner wall of the pipe fitting, the rotating assembly and the pipe fitting are rotated 90°, that is, rotated to the position directly below the cylindrical tube 300, and the rotation is stopped. The pipe fitting is located at the clamping assembly, and then the positioning of the pipe fitting by the positioning assembly 500 is canceled, and the positioning assembly 500 is separated from the end of the pipe fitting by moving the hydraulic telescopic rod 401 and adjusting the position of the adjustment assembly, and then the clamping assembly is started to clamp the pipe fitting and move down to correspond to the position of the fixed tube 103, and the height position is staggered with the positioning assembly 500 and other structures to avoid the positioning assembly 500 and other structures from affecting the movement of the second grinding assembly, and then the second grinding assembly is started to move along the length direction of the pipe fitting, and during the movement, the inside of the pipe fitting is ground by the second grinding assembly;

[0057] After the inner wall of the pipe is polished, the second polishing assembly returns to its position and detaches from the pipe, and the clamping assembly drives the pipe to move up to the corresponding height position. The positioning assembly 500 is reconnected to the end of the pipe and realizes the positioning function under the coordinated adjustment of the mobile hydraulic telescopic rod 401 and the adjustment assembly, and then the clamping assembly is detached from the pipe to realize the switching of the positioning methods of different positions of the pipe.

[0058] When the pipe rotates again, the rotating assembly drives the positioning assembly 500 and the pipe to rotate to the right along the arc groove 101, and during the rotation, it contacts the cleaning plate 203 on the other side, and the outer wall of the pipe is cleaned and dusted by the cleaning plate 203. The positioning assembly 500 drives the pipe to rotate, so that the outer wall is cleaned more comprehensively. After cleaning, the pipe moves to the right side of the cylindrical barrel 300 for unloading operations, etc.

[0059] When the pipe is being loaded, the positioning mode is switched, and the pipe is unloaded, the positioning assembly 500 is disengaged from the pipe, and the rotating assemblies on both sides are simultaneously moved outward by moving the hydraulic telescopic rod 401, thereby expanding the distance between the two corresponding positioning assemblies 500, so that the pipe on the left side of the cylindrical barrel 300 can be placed between the two positioning assemblies 500, and the pipe below the cylindrical barrel 300 is disengaged from the two positioning assemblies 500 for clamping positioning and inner wall grinding, while the pipe on the right side of the cylindrical barrel 300 is disengaged from the positioning assembly 500 for unloading operations in cooperation with manual or conveying devices; and, when the positioning assembly 500 is returned to its original position by moving the hydraulic telescopic rod 401 and the adjusting assembly, the pipe on the left side and the pipe below can both be positioned by the positioning assemblies 500 at the corresponding positions for subsequent operations.

[0060] During the grinding process, waste materials and the like fall into the aggregate trough 102 along the bottom of the arc groove 101, and the dust-containing air at the processing table is moved downward by the suction fan 105, so that the waste dust and the like generated by the grinding are driven downward by the airflow and enter the aggregate trough 102, and the dust and the like are retained in the aggregate trough 102 by the dust filter net 104 for subsequent processing.

[0061] Among them, Figure 2 As shown, the rotating assembly includes a mobile ring 400 slidably connected to the cylindrical barrel 300, the mobile ring 400 is connected to the support plate 301 on the corresponding side through a mobile hydraulic telescopic rod 401, and a rotating ring 402 is rotatably connected to the mobile ring 400. Figure 6 As shown, a transmission ring gear 407 is fixed on one side of the rotating ring stage 402, and the transmission ring gear 407 is meshed with a driving gear 408. The driving gear 408 is connected to a motor, and the motor is fixed on the moving ring stage 400. Four sliding frames 403 are evenly arranged on the rotating ring stage 402 along the circumferential direction, and the positioning assembly 500 is located in the sliding frame 403.

[0062] After the pipe is positioned, the driving gear 408 is rotated by the motor, and the rotating ring 402 drives the four sliding frames 403 to rotate through the transmission of the driving gear 408 and the transmission gear ring 407, so as to drive the pipe to rotate and switch positions.

[0063] Among them, Figure 3 As shown, the positioning assembly 500 includes a sliding seat 405 slidably connected to the sliding frame 403, and the sliding seat 405 is correspondingly connected to the adjustment assembly, one end of the sliding seat 405 is connected to the sliding seat 405 through a spring, and limiting sliding shafts 406 are symmetrically fixed on both sides of the sliding seat 405, and limiting sliding grooves 404 are provided on both side walls of the sliding frame 403, and the limiting sliding shafts 406 are slidably connected to the limiting sliding grooves 404, and the sliding seat 405 is rotatably connected with a first rotating shaft 504, and the first rotating shaft 504 is connected to a plurality of positioning blocks 502 evenly arranged along the circumferential direction through a first adjusting structure, and one end of the first rotating shaft 504 passes through the sliding seat 405 and is connected to a motor.

[0064] When the positioning assembly 500 adjusts its position and approaches the pipe under the action of the moving ring stage 400 and other structures, the sliding seat 405 drives the positioning assembly 500 to move on the sliding frame 403 through the adjustment assembly, so that the positioning assembly 500 can be located at the center of the end of the pipe, and multiple positioning blocks 502 are located on the inner side of the end of the pipe, and then the multiple positioning blocks 502 are moved outward at the same time through the first adjustment structure, so as to approach the end of the pipe and position the pipe. Then, when the pipe moves along the arc-shaped grinding plate 202 with the material transfer assembly, the first rotating shaft 504 is driven by the motor to drive the pipe to rotate through multiple positioning blocks 502, so that the outer side wall of the pipe can rotate relative to the grinding plate 202 and be polished; a protrusion can be set at the end of the outer side surface of the positioning block 502, so that the end of the pipe can be stuck at the protrusion, and the length direction of the pipe can be limited while radially positioning.

[0065] Among them, Figure 2 As shown, the adjustment assembly includes two adjustment ring plates 302 that slide symmetrically on the cylindrical barrel 300, an adjustment rod 303 that is tilted toward the cylindrical barrel 300 is rotatably connected to the sliding seat 405, and the other end of the adjustment rod 303 is rotatably connected to the adjustment ring plate 302 on the corresponding side, a movable ring plate 311 is rotatably connected to one side of the adjustment ring plate 302, a vertical adjustment block 309 is fixed in the middle of the movable ring plate 311, the adjustment block 309 is located in the cylindrical barrel 300, and adjustment grooves 310 are provided at the two end positions of the cylindrical barrel 300 corresponding to the adjustment block 309, an adjustment screw 304 is threadedly connected in the adjustment block 309, the adjustment screw 304 is rotatably connected to the cylindrical barrel 300, and the first bevel gears 305 are respectively fixed at the proximal ends, as shown in FIG. Figure 4As shown, a second bevel gear 306 is meshed between the bottoms of the two first bevel gears 305 , and the second bevel gear 306 is connected to a motor.

[0066] When positioning the two ends of the pipe fitting, the adjusting screws 304 on both sides are rotated through the drive of the motor and the transmission of the first bevel gear 305 and the second bevel gear 306, thereby driving the adjusting ring plate 302 to move through the adjusting block 309 and the movable ring plate 311, and then driving the sliding seat 405 to move in the sliding frame 403 through the adjusting rod 303, thereby realizing the position adjustment of the positioning component 500, so that the positioning component 500 corresponds to the center position of the pipe fitting.

[0067] Among them, Figure 8 As shown, the second grinding assembly includes two parallel moving frames 600 symmetrically located on the fixed cylinder 103, a moving plate 602 is commonly fixed between the inner ends of the two moving frames 600, the moving plate 602 is rotatably connected to the second rotating shaft 604, the second rotating shaft 604 is connected to a plurality of grinding blocks 607 evenly arranged along the circumferential direction through a second adjusting structure, one end of the second rotating shaft 604 passes through the moving plate 602 and is connected to a motor, a tooth groove is provided on one side of the moving frame 600 close to the fixed cylinder 103, a plurality of teeth are evenly arranged in the tooth groove, two moving gears 601 are rotatably connected at corresponding positions on the side wall of the fixed cylinder 103, the moving gear 601 is connected to a motor and meshes with the teeth in the moving frame 600 on the corresponding side.

[0068] After the pipe is fixed by the clamping assembly, the moving gear 601 is driven by the motor, and the moving gear 601 cooperates with the teeth to make the moving frame 600 drive the moving plate 602 to move toward the pipe. During the movement, the positions of the multiple grinding blocks 607 are adjusted by the second adjustment structure so that they can contact the inner wall of the pipe. The second rotating shaft 604 and the grinding block 607 are driven by the motor to rotate, so as to grind the inner wall of the pipe. The waste dust polished out can fall into the collecting trough 102 through the action of the rotating grinding block 607 and the suction fan 105 and other structures.

When the first spring plate 505 and the second spring plate 606 rotate, the friction of the movement is reduced by the balls, thereby improving the flexibility of the movement.

[0076] Embodiment 4: The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 7 As shown, a discharge port is provided in the middle of the bottom of the aggregate trough 102, and guide plates 106 inclined toward the discharge port are symmetrically provided on both sides of the aggregate trough 102, and a sealing plate 107 is slidably connected to the bottom of the discharge port. One end of the sealing plate 107 is connected to the bottom of the aggregate trough 102 through an electric telescopic rod, and the waste dust and the like in the aggregate trough 102 are concentrated at the discharge port through the guide plate 106. When the dust needs to be cleaned, the sealing plate 107 is moved by the electric telescopic rod to open the discharge port so that the dust and the like can be discharged through the discharge port.

[0077] Embodiment 5: The structure of this embodiment is basically the same as that of embodiment 1, except that Fig.10 As shown, a spring groove 208 is provided at the top of the arc plate 200, and the bottoms of the grinding plate 202 and the cleaning plate 203 are respectively connected to the spring groove 208 through a plurality of evenly arranged springs. The springs enable the grinding plate 202 and the cleaning plate 203 to contact the outer wall of the pipe more fully, thereby improving the grinding and cleaning effects.
