Description

Technical Field

[0001] The invention relates to the technical field of automatic grinding machines, in particular to an automatic grinding device for spherical castings. Background Art

[0002] During the welding process, surface defects such as burrs and protrusions may occur at the weld of round castings, which will affect the appearance and performance of the castings. Through grinding and polishing, these defects can be removed to make the surface smoother. Grinding and polishing can not only improve the appearance of the casting, but also improve its performance and life. The smooth surface reduces the possibility of friction and corrosion, thereby extending the service life of the casting.

[0003] However, when the weld on the sphere is processed by a belt grinder, fine waste chips will be generated during the weld grinding and polishing process. These waste chips are mainly composed of metal and mineral dust. The dust is suspended in the air and can easily cause discomfort after inhalation into the human body, posing a safety hazard; when the waste chips accumulate on the swinging workbench, it is easy to increase the friction between the workbench and the base, thereby affecting the swinging effect of the sphere during grinding; after grinding, the operator needs to manually place the processed sphere in a fixed position.

[0011] The beneficial effects of the present invention are:

[0012] (1) The automatic grinding device for spherical castings described in the present invention can clamp and limit the ball through a rotating mechanism, and can also drive the ball to rotate. The grinding mechanism is started to slide in the direction close to the ball and polish the weld of the ball while rotating. That is, the operator places the ball to be polished on the first limit block, and then starts the control switch of the hydraulic rod so that the telescopic end can drive the second limit block to resist the side wall of the ball when sliding along the bracket, so that the ball is located between the first limit block and the second limit block. Then the first motor can be started, and the first motor drives the screw rod to rotate inside the fixed plate. Since the screw rod is threadedly connected to the support plate, when the screw rod starts to rotate, the support plate can be The support plate slides along the inner wall of the fixed plate under the limiting action of the slide groove, and the support plate drives the mounting frame to move toward the direction close to the sphere, so that the sanding belt sleeved on the driving wheel can contact the side wall of the sphere, and then the control switch of the driving wheel is turned on to make it rotate along the side wall of the mounting frame, and the driving wheel drives the sanding belt to move at high speed, so that the sanding belt grinds and polishes the weld on the sphere; during the grinding process, the second motor is started, so that the rotating rod can drive the first limit block to rotate, and then the first limit block drives the sphere to rotate, because the second limit block is in contact with the sphere, and the second limit block is rotatably connected with the telescopic end of the hydraulic rod, when the sphere rotates, the second limit block rotates along the telescopic end of the hydraulic rod, so as to facilitate the grinding of the welds at different parts of the sphere side wall.

[0013] (2) The automatic grinding device for spherical castings described in the present invention can collect the waste chips generated during the grinding process through a collecting mechanism, and the swing mechanism drives the ball clamped on the rotating mechanism to move, so that the grinding effect of the ball is better, that is: during the grinding process, the control switch of the third motor is turned on, and the rotating shaft installed on the third motor can rotate inside the support seat, and the support seat is located on the top of the bottom plate. When the rotating shaft rotates, it can drive the sleeve rod to rotate inside the support seat. A sliding rod is rotatably connected to the sleeve rod, and the sliding rod and the connecting rod are slidably connected. When the sleeve rod drives the sliding rod to rotate, the sliding rod is limited by the connecting rod and can only slide along the side wall of the connecting rod. The sliding rod drives the connecting rod to swing in the support seat, and the connecting rod A mounting block is fixed at the end, and the mounting block rotates in the support seat as the connecting rod swings, and the fixing rod fixed on the mounting block also rotates accordingly. The fixing rod is fixedly connected to the mounting plate, and a bracket is fixed on the mounting plate. The hydraulic rod and the second motor are installed on the bracket. When the fixing rod rotates, the mounting plate can drive the bracket to swing back and forth, thereby causing the ball clamped between the first limit block and the second limit block to be displaced, so that different parts of the ball can contact the sand belt, thereby improving the grinding effect of the ball; the waste chips generated during the grinding process will fall into the interior of the ash collecting box. Since two clamping plates are fixedly installed at the bottom end of the ash collecting box, when disassembling, the clamping plates are taken out from the clamping slots provided on the mounting plate, and the waste chips collected in the ash collecting box can be cleaned.

Since baffles are fixedly installed on both sides of the guide plate, the setting of the baffles can prevent the balls from falling from the top of the guide plate to the outside of the storage box, so that the operation steps of the operators for placing the balls can be reduced while facilitating the storage of the ground balls, which is conducive to the centralized transportation of the processed balls.

[0029] Specifically, Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, the collecting mechanism 4 includes an ash box 401 and a card plate 402, two card plates 402 are mounted on the mounting plate 701, the top of the card plate 402 is fixedly connected with the ash box 401, the ash box 401 is fixedly connected with a pull rod 403, and two card slots 404 are symmetrically provided on the mounting plate 701.

[0030] Specifically, Figure 1 , Figure 4 and Figure 5As shown, the rotating mechanism 3 includes a bracket 301 and a hydraulic rod 303. Two brackets 301 are symmetrically fixedly connected to the mounting plate 701. A hydraulic rod 303 is fixedly installed on one of the brackets 301. The telescopic end of the hydraulic rod 303 is rotatably connected to a second limit block 306. A second motor 302 is fixedly installed on the other bracket 301. The output end of the second motor 302 is fixedly connected to a rotating rod 304 through a coupling. The rotating rod 304 is fixedly connected to a first limit block 305. The rotating rod 304 is rotatably connected to the bracket 301. The telescopic end is slidably connected with the bracket 301, and the waste chips generated during the grinding process can be collected by the collecting mechanism 4. The swing mechanism 7 drives the ball clamped on the rotating mechanism 3 to move, so that the grinding effect of the ball is better, that is: during the grinding process, the control switch of the third motor 706 is turned on, and the rotating shaft 707 installed on the third motor 706 can rotate inside the support seat 702. The support seat 702 is located on the top of the bottom plate 6. When the rotating shaft 707 rotates, it can drive the sleeve rod 708 to rotate inside the support seat 702. The sleeve rod 708 is rotatably connected with a sliding rod 709, and the sliding rod 709 is connected to the connecting rod 7 05 is slidably connected. When the sleeve rod 708 drives the sliding rod 709 to rotate, the sliding rod 709 is limited by the connecting rod 705 and can only slide along the side wall of the connecting rod 705. The sliding rod 709 slides and drives the connecting rod 705 to swing in the support seat 702, and the end of the connecting rod 705 is fixed with a mounting block 704. The mounting block 704 rotates in the support seat 702 as the connecting rod 705 swings, and the fixing rod 703 fixed on the mounting block 704 also rotates. The fixing rod 703 is fixedly connected to the mounting plate 701. The mounting plate 701 is fixed with a bracket 301, and the hydraulic rod 303 and the second motor 302 are mounted On the bracket 301, when the fixing rod 703 rotates, the mounting plate 701 can drive the bracket 301 to swing back and forth, thereby causing the sphere clamped between the first limit block 305 and the second limit block 306 to be displaced, so that different parts of the sphere can contact the sanding belt 204, thereby improving the grinding effect of the sphere; the waste chips generated during the grinding process will fall into the interior of the ash collecting box 401. Since two clamping plates 402 are fixedly installed at the bottom end of the ash collecting box 401, when disassembling, the clamping plates 402 are taken out from the clamping grooves 404 provided on the mounting plate 701, and the waste chips collected in the ash collecting box 401 can be cleaned.

[0031] Specifically, Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the grinding mechanism 2 includes a fixed plate 205 and a screw 206. The top of the base 1 is fixedly connected to the fixed plate 205, and a first motor 208 is fixedly installed on the fixed plate 205. The output end of the first motor 208 is fixedly connected to the screw 206 through a coupling. A slide groove 207 is provided in the fixed plate 205. The screw 206 is threadedly connected to a support plate 201. A mounting frame 202 is fixedly installed on the support plate 201. A plurality of driving wheels 203 are rotatably connected to the mounting frame 202. A sanding belt 204 is sleeved on the driving wheel 203. The rod 206 is rotatably connected to the fixed plate 205, and the support plate 201 is slidably connected to the fixed plate 205. The ball can be clamped and limited by the rotating mechanism 3, and the ball can also be driven to rotate. The grinding mechanism 2 is started to slide in the direction close to the ball and polish the weld of the ball during rotation, that is, the operator places the ball to be polished on the first limit block 305, and then starts the control switch of the hydraulic rod 303, so that the telescopic end can slide along the bracket 301 to drive the second limit block 306 to contact the side wall of the ball, so that the ball is located in the first limit block. The first motor 208 can then be started to drive the screw rod 206 to rotate inside the fixed plate 205. Since the screw rod 206 is threadedly connected with the support plate 201, when the screw rod 206 starts to rotate, the support plate 201 can slide along the inner wall of the fixed plate 205 under the limiting effect of the slide groove 207. The support plate 201 drives the mounting frame 202 to move toward the direction close to the ball, so that the sanding belt 204 sleeved on the driving wheel 203 can contact the side wall of the ball. Then, the control switch of the driving wheel 203 is turned on to make it slide along the inner wall of the fixed plate 205. The side wall of the mounting frame 202 rotates, and the driving wheel 203 drives the sanding belt 204 to move at high speed, so that the sanding belt 204 grinds and polishes the weld on the ball; during the grinding process, the second motor 302 is started, and the rotating rod 304 can drive the first limit block 305 to rotate, and then the first limit block 305 drives the ball to rotate. Since the second limit block 306 is in contact with the ball, and the second limit block 306 is rotatably connected to the telescopic end of the hydraulic rod 303, when the ball rotates, the second limit block 306 rotates along the telescopic end of the hydraulic rod 303, so as to facilitate the grinding of the welds at different parts of the side wall of the ball.

[0032] Specifically, Figure 1 and Figure 3As shown, the storage mechanism 5 includes a storage box 501 and a baffle 503, two baffles 503 are slidably connected to the bottom plate 6, the storage box 501 is fixedly installed on the baffle 503, two sets of universal wheels 502 are rotatably installed on the storage box 501, a support block 504 and a guide plate 505 are fixedly installed between the two baffles 503, a plurality of guide rollers 506 are rotatably connected to the guide plate 505, the guide plate 505 is inclined, and the plurality of guide rollers 506 are equidistantly arranged, the support block 504 is in contact with the top of the bottom plate 6, and the baffle 503 is arranged in an inclined structure, the polished balls are taken down, and the processed balls can be stored centrally through the storage mechanism 5, so as to facilitate the subsequent storage of the balls. Transportation, that is: after the ball is polished, turn off the second motor 302 to stop the rotating rod 304, and the hydraulic rod 303 drives the second limit block 306 to reset, so that the second limit block 306 is separated from the side wall of the ball, so that it is convenient to take the polished ball down, and then put the ball down along the guide roller 506 installed on the guide plate 505, so that it rolls along the guide roller 506 and falls into the storage box 501 for storage. Since baffles 503 are fixedly installed on both sides of the guide plate 505, the setting of the baffle 503 can prevent the ball from falling from the top of the guide plate 505 to the outside of the storage box 501, so that when it is convenient to store the polished balls, it can also reduce the operating steps of the operator to place the balls, which is conducive to the centralized transportation of the processed balls.

[0033] When the present invention is in use, first, the operator places the ball to be polished on the first limit block 305, and then starts the control switch of the hydraulic rod 303, so that when the telescopic end thereof slides along the bracket 301, it can drive the second limit block 306 to resist the side wall of the ball, thereby making the ball be located between the first limit block 305 and the second limit block 306, and then the first motor 208 can be started, and the first motor 208 drives the screw rod 206 to rotate inside the fixed plate 205. Since the support plate 201 is threadedly connected to the screw rod 206, when the screw rod 206 starts to rotate, the support plate 201 can slide along the inner wall of the fixed plate 205 under the limiting action of the slide groove 207, and the support plate 201 drives the mounting frame 202 to approach the ball. The displacement can make the sanding belt 204 sleeved on the driving wheel 203 contact with the side wall of the ball, and then turn on the control switch of the driving wheel 203 to make it rotate along the side wall of the mounting frame 202, and the driving wheel 203 drives the sanding belt 204 to move at high speed, so that the sanding belt 204 grinds and polishes the weld on the ball; during the grinding process, the second motor 302 is started, and the rotating rod 304 can drive the first limit block 305 to rotate, and then the first limit block 305 drives the ball to rotate. Since the second limit block 306 is in contact with the ball, and the second limit block 306 is rotatably connected with the telescopic end of the hydraulic rod 303, when the ball rotates, the second limit block 306 rotates along the telescopic end of the hydraulic rod 303, so as to facilitate the grinding of the welds at different parts of the side wall of the ball;

[0034] During the grinding process, the control switch of the third motor 706 is turned on, and the rotating shaft 707 installed on the third motor 706 can rotate inside the support seat 702. The support seat 702 is located on the top of the bottom plate 6. When the rotating shaft 707 rotates, it can drive the sleeve rod 708 to rotate inside the support seat 702. The sleeve rod 708 is rotatably connected with a sliding rod 709, and the sliding rod 709 is slidably connected with the connecting rod 705. When the sleeve rod 708 drives the sliding rod 709 to rotate, since the sliding rod 709 is limited by the connecting rod 705, it can only slide along the side wall of the connecting rod 705. The sliding rod 709 slides and drives the connecting rod 705 to swing in the support seat 702, and a mounting block 704 is fixed at the end of the connecting rod 705. The mounting block 704 rotates in the support seat 702 as the connecting rod 705 swings. The fixing rod 703 also rotates, and the fixing rod 703 is fixedly connected to the mounting plate 701. The mounting plate 701 is fixed with a bracket 301, and the hydraulic rod 303 and the second motor 302 are mounted on the bracket 301. When the fixing rod 703 rotates, the mounting plate 701 can drive the bracket 301 to swing back and forth, thereby causing the ball clamped between the first limit block 305 and the second limit block 306 to move, so that different parts of the ball can contact the sand belt 204, which is convenient for improving the grinding effect of the ball; the waste chips generated during the grinding process will fall into the interior of the ash collecting box 401. Since two clamping plates 402 are fixedly installed at the bottom end of the ash collecting box 401, when disassembling, the clamping plate 402 is taken out from the clamping groove 404 provided on the mounting plate 701, and the waste chips collected in the ash collecting box 401 can be cleaned;

[0035] After the ball is polished, the second motor 302 is turned off to stop the rotating rod 304, and the hydraulic rod 303 drives the second limit block 306 to reset, so that the second limit block 306 is separated from the side wall of the ball, so that it is convenient to take down the polished ball, and then the ball is lowered along the guide roller 506 installed on the guide plate 505, so that it rolls along the guide roller 506 and falls into the storage box 501 for storage. Since baffles 503 are fixedly installed on both sides of the guide plate 505, the setting of the baffle 503 can prevent the ball from falling from the top of the guide plate 505 to the outside of the storage box 501, thereby reducing the operating steps of the operator in placing the ball while facilitating the storage of the polished balls, which is conducive to the centralized transportation of the processed balls.
