Technical Field
[0001] This utility model belongs to the field of polishing machines, and more specifically, it relates to a magnetic polishing device for small-sized parts. Background Technology
[0002] In the processing of general mechanical parts and motorcycle parts, some parts need to undergo deburring and polishing processes. Due to the complex shape of some parts, with irregular surfaces such as gaps, threads, internal holes, and right angles, magnetic polishing machines are usually used for such complex parts. Magnetic polishing machines use magnetic fields to drive stainless steel polishing needles to rotate rapidly inside the polishing barrel, continuously impacting, rubbing, and tumbling the surface of the workpiece to polish it.
[0003] Most existing polishing machines use grinding needles for polishing. Since most grinding needles are cylindrical, they are difficult to clean in places such as irregularly shaped parts, holes, tubes, dead corners, and crevices, thus affecting the cleaning effect.
[0004] In view of this, this utility model is proposed. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a magnetic polishing device for small-sized parts. This solves the technical problem that columnar grinding needles are difficult to clean in place when there are irregularly shaped parts, holes in parts, tubes in parts, dead corners of parts, and gaps in parts.
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0007] A magnetic polishing device for small-sized parts includes: a polishing equipment body; a rotating device mounted on the top of the polishing equipment body; a support frame mounted on one side of the polishing equipment body; a placement box mounted inside the support frame; and a grinding device placed inside the placement box. The grinding device includes multiple arc-shaped grinding needles, which are placed inside the placement box. Multiple grinding protrusions are mounted around the surface of each arc-shaped grinding needle. The arc-shaped grinding needle has a semi-arc shape, and the grinding protrusions are cone-shaped. The grinding protrusions are evenly mounted on the surface of the arc-shaped grinding needle, and the surface of the grinding protrusions is frosted.
[0008] To achieve the above technical solution, an arc-shaped grinding needle is set. Since the arc-shaped grinding needle is arc-shaped, it can grind various dead corners and crevices of the object. The arc shape of the grinding needle can also increase the contact area between the arc-shaped grinding needle and the object. By setting grinding protrusions, the contact area can be further increased when the grinding protrusions come into contact with the object.
[0009] Optionally, the rotating device includes a drive motor. The top of the polishing equipment body is equipped with two fixed plates. The drive motor is installed on one side of one of the fixed plates. The output end of the drive motor is equipped with a rotating rod one. A support rod is installed on one side of the other fixed plate. A rotating rod two is sleeved inside the support rod. An arc-shaped fixing block is installed at one end of both the rotating rod two and the rotating rod one. A fixing device is installed inside the arc-shaped fixing block.
[0010] To achieve the above technical solution, the staff starts the drive motor. The output end of the drive motor rotates, which drives the rotating rod to rotate, and the rotating rod drives the polishing barrel to rotate.
[0011] Optionally, the fixing device includes two fixing blocks, one of which has a slot inside, and a clamping block is slidably fitted inside the slot. The clamping block is fixedly connected to the other fixing block. The clamping block has two fixing grooves inside, and one of the fixing blocks is equipped with a snap-fit component.
[0012] To achieve the above technical solution, the arc-shaped fixing block moves, causing the clamping block to move. When the clamping block moves to contact the T-shaped push rod, the T-shaped push rod moves. When the T-shaped push rod moves to correspond to the through groove, under the action of the spring, the locking rod is engaged inside the fixing groove, thereby fixing the clamping block inside the locking groove.
[0013] Optionally, the snap-fit assembly includes a T-shaped push rod, which is slidably fitted inside the fixing block. One end of the T-shaped push rod extends into the inside of the snap-fit groove. A second spring is installed inside the fixing block, and the end of the second spring near the T-shaped push rod is fixedly connected to the T-shaped push rod. Two moving blocks are slidably fitted inside the fixing block. A snap-fit rod is installed on the side of the moving block near the clamping block. One end of the snap-fit rod extending into the snap-fit groove is snapped into the inside of the fixing groove. A through groove is opened inside the moving block, and the T-shaped push rod slides through the through groove to engage with the moving block.
[0014] To achieve the above technical solution, the arc-shaped fixing block moves, causing the clamping block to move. When the clamping block moves to contact the T-shaped push rod, the T-shaped push rod moves. When the T-shaped push rod moves to correspond to the through groove, under the action of the spring, the locking rod is engaged inside the fixing groove, thereby fixing the clamping block inside the locking groove.
[0015] Optionally, the fixing block is equipped with two limiting blocks, the first limiting block being slidably engaged with the locking rod, and the fixing block is equipped with a second limiting block, the second limiting block being slidably engaged with the T-shaped push rod.
[0016] To achieve the above technical solution, by setting limit block one, the locking rod can be limited and kept stable during the operation of the locking rod. By setting limit block two, the T-shaped push rod can be limited and kept stable during the operation of the T-shaped push rod.
[0017] Optionally, a spring is installed between the limiting block and the moving block. The spring is sleeved on the outside of the locking rod. Two pull rods are slidably fitted inside the fixing block. One end of the pull rod extends into the interior of the fixing block and is fixedly connected to the moving block.
[0018] To achieve the above technical solution, spring one allows the locking rod to move, and by setting a pull rod, the operator can move the locking rod out of the fixed groove.
[0019] Optionally, a polishing barrel is placed on the top of the polishing equipment body, two support plates are installed on one side of the polishing equipment body, a filter box is slidably fitted between the two support plates, and a collection box is placed on one side of the bottom of the polishing equipment body, the collection box being located at the bottom of the filter box.
[0020] To achieve the above technical solution, when the discharge port of the polishing barrel rotates to correspond with the filter box, the object can be filtered out by setting up the filter box, so that the arc-shaped grinding needle and grinding liquid flow into the inside of the collection box, which is convenient for staff to collect in a centralized manner.
[0021] Optionally, an operation button is provided on one side of the top of the polishing equipment body, and a control screen is provided on one side of the top of the polishing equipment body.
[0022] To achieve the above technical solution, staff can start the polishing equipment by operating the operation buttons, control the rotation speed inside the polishing barrel by setting the polishing equipment, and control the polishing equipment by setting the control screen, thereby improving the practicality of the polishing equipment's grinding function.
[0023] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0024] By setting up arc-shaped grinding needles, which are arc-shaped, various dead corners and crevices of objects can be ground. The arc shape of the grinding needles also increases the contact area between the grinding needles and the objects, thereby increasing the grinding effect. By setting up grinding protrusions, the contact area can be further increased when the grinding protrusions come into contact with the objects, thus meeting the needs of workers for arc-shaped grinding needles.

Detailed Implementation
[0034] The present invention will now be described in further detail with reference to the accompanying drawings.
[0035] Please see Figure 1 As shown, this embodiment provides a magnetic polishing device for small-sized parts, including a polishing equipment body 1; a rotating device mounted on the top of the polishing equipment body 1; a support frame 4 mounted on one side of the polishing equipment body 1; a placement box 401 installed inside the support frame 4; and a grinding device placed inside the placement box 401. Specifically, in conjunction with... Figure 2 As shown, the grinding device includes multiple arc-shaped grinding needles 402. Since the arc-shaped grinding needles 402 are arc-shaped, they can grind various dead corners and crevices of the object. The arc-shaped grinding needles 402 are placed inside the placement box 401. Multiple grinding protrusions 403 are installed around the surface of the arc-shaped grinding needles 402. By setting the grinding protrusions 403, the contact area can be further increased when the grinding protrusions 403 come into contact with the object. The overall shape of the arc-shaped grinding needles 402 is semi-arc, and the grinding protrusions 403 are set in a cone shape. The grinding protrusions 403 are evenly installed on the surface of the arc-shaped grinding needles 402. The surface of the grinding protrusions 403 is set in a frosted state to increase the friction of the surface of the grinding protrusions 403.
[0036] Please see Figure 1 As shown, the rotating device includes a drive motor 2. Two fixed plates 201 are mounted on the top of the polishing equipment body 1. The drive motor 2 is mounted on one side of one of the fixed plates 201. A rotating rod 202 is mounted on the output end of the drive motor 2. A support rod 203 is mounted on one side of the other fixed plate 201. A rotating rod 204 is fitted inside the support rod 203. An arc-shaped fixing block 205 is mounted on one end of both the rotating rod 204 and the rotating rod 202. A fixing device is installed inside the arc-shaped fixing block 205. When the operator starts the drive motor 2, the output end of the drive motor 2 rotates, causing the rotating rod 202 to rotate, which in turn causes the polishing barrel 3 to rotate.
[0037] Please see Figure 3-4As shown, the fixing device includes two fixing blocks 501. One fixing block 501 has a slot 509 inside, and a clamping block 502 is slidably fitted inside the slot 509. The clamping block 502 is fixedly connected to the other fixing block 501. The clamping block 502 has two fixing grooves 504 inside. One fixing block 501 has a snap-fit assembly inside, which includes a T-shaped push rod 508. The T-shaped push rod 508 is slidably fitted inside the fixing block 501, and one end of the T-shaped push rod 508 extends into the slot 509. The fixed block 501 is equipped with a second spring 510. One end of the second spring 510 near the T-shaped push rod 508 is fixedly connected to the T-shaped push rod 508. The fixed block 501 has two sliding blocks 503 inside. The side of the sliding block 503 near the clamping block 502 is equipped with a locking rod 506. One end of the locking rod 506 extends into the locking groove 509 and is locked inside the fixed groove 504. The sliding block 503 has a through groove 505 inside. The T-shaped push rod 508 slides with the sliding block 503 through the through groove 505. The movement of the arc-shaped fixing block 205 drives the clamping block 502 to move. When the clamping block 502 moves to contact the T-shaped push rod 508, the T-shaped push rod 508 moves. When the T-shaped push rod 508 moves to correspond to the through groove 505, under the action of the spring 507, the locking rod 506 is locked inside the fixing groove 504, thereby fixing the clamping block 502 inside the locking groove 509.
[0038] The fixing block 501 is internally equipped with two limiting blocks 6, which slide in engagement with the locking rod 506. The fixing block 501 is also internally equipped with a second limiting block 7, which slides in engagement with the T-shaped push rod 508. By setting the first limiting block 6, the locking rod 506 can be limited, maintaining stability during its operation. Similarly, by setting the second limiting block 7, the T-shaped push rod 508 can be limited, maintaining stability during its operation.
[0039] Preferably, a spring 507 is installed between the limiting block 6 and the moving block 503. The spring 507 is sleeved on the outside of the locking rod 506. Two pull rods 5 are slidably fitted inside the fixing block 501. One end of the pull rod 5 extends into the interior of the fixing block 501 and is fixedly connected to the moving block 503.
[0040] Back Figure 1The polishing equipment body 1 has a polishing barrel 3 placed on top. Two support plates 301 are installed on one side of the polishing equipment body 1, and a filter box 302 is slidably fitted between the two support plates 301. A collection box 303 is placed on one side of the bottom of the polishing equipment body 1, and the collection box 303 is located at the bottom of the filter box 302. By setting a pull rod 5, the operator can move the clamping rod 506 out of the fixed groove 504. When the discharge port of the polishing barrel 3 is rotated to correspond with the filter box 302, the filter box 302 can filter out the object, allowing the arc-shaped grinding needle 402 and the grinding liquid to flow into the collection box 303 for convenient collection by the operator.
[0041] Furthermore, an operation button 101 and a control screen 102 are provided on one side of the top of the polishing equipment body 1. Operators can start the polishing equipment body 1 by operating the operation button 101, control the rotation speed inside the polishing barrel 3 by setting the polishing equipment body 1, and control the polishing equipment body 1 by setting the control screen 102, thereby improving the practicality of the polishing equipment body 1 in grinding.
[0042] One application of this embodiment is as follows: During use, the operator removes the arc-shaped grinding needle 402 from the placement box 401 and places it into the polishing barrel 3. The operator then places the object into the polishing barrel 3 and the grinding liquid into it. At this time, the operator can start the polishing equipment body 1 by operating the operation button 101. The rotation speed inside the polishing barrel 3 can be controlled by setting the polishing equipment body 1, and the polishing equipment body 1 can be controlled by setting the control screen 102, thereby improving the practicality of the polishing equipment body 1. After grinding is completed, the operator moves the rotating rod 204. The movement of the rotating rod 204 drives the arc-shaped fixing block 205 to move, and the movement of the arc-shaped fixing block 205 drives the clamping block 502. When the clamping block 502 moves to contact the T-shaped push rod 508, the T-shaped push rod 508 moves. When the T-shaped push rod 508 moves to correspond with the through groove 505, under the action of the spring 507, the locking rod 506 is locked inside the fixing groove 504, thereby fixing the clamping block 502 inside the locking groove 509. The operator starts the drive motor 2, and the output end of the drive motor 2 rotates to drive the rotating rod 202 to rotate. The rotating rod 202 rotates to drive the polishing barrel 3 to rotate. When the discharge port of the polishing barrel 3 rotates to correspond with the filter box 302, the object can be filtered out by setting the filter box 302, so that the arc-shaped grinding needle 402 and the grinding liquid flow into the collection box 303 for the operator to collect.
