Description

Technical Field

[0001] This application relates to the field of workpiece processing, and particularly to a workpiece grinding device. Background Art

[0002] A workpiece is a product component during the manufacturing process, also known as a fabricated part, workpiece, courseware, hardware part, etc. It can be a single part or a combination of several parts fixed together. There are various types of workpiece processing methods, such as turning, milling, planing, grinding, casting, forging, etc. The processing procedures of workpieces also change with the processing methods. When processing a workpiece, it is necessary to grind the workpiece.

[0003] When the grinding mechanism grinds the workpiece, it is necessary to use a clamping mechanism to clamp and lock the workpiece. When processing some circular workpieces, sometimes it is necessary to grind the outer wall of the workpiece, and sometimes it is necessary to grind the inner wall of the workpiece. When the clamping mechanism clamps the outer wall of the circular workpiece, it may block the outer wall of the workpiece, thus affecting the grinding effect of the workpiece. Summary of the Invention

[0004] In order to ensure the grinding effect of the workpiece, this application provides a workpiece grinding device.

[0005] A workpiece grinding device provided by this application adopts the following technical solution: A workpiece grinding device includes a working platform, a grinding mechanism and a locking mechanism installed on the working platform. The locking mechanism includes two adjusting rods slidably connected to the working platform, and also includes a driving component for driving the two adjusting rods to move towards or away from each other. Two clamping plates are rotatably connected to each adjusting rod, and the adjusting rod is located between the two clamping plates. Each adjusting rod is provided with an adjusting member for driving the two clamping plates to rotate towards or away from each other. Each clamping plate is used to abut against the outer wall or the inner wall of the workpiece.

[0006] By adopting the above technical solution, the workpiece grinding device can stably clamp the inner and outer walls of circular workpieces with different sizes. Specifically, by setting two adjusting rods and a driving component, the two adjusting rods can move relative to each other, so as to adapt to workpieces of different sizes. The two clamping plates on each adjusting rod can rotate under the action of the adjusting member, further adjusting the clamping angle to adapt to workpieces of different diameters, ensuring that the clamping plates accurately abut against the outer wall or the inner wall of the workpiece, improving the clamping stability, and providing a reliable guarantee for the subsequent grinding operation. When it is necessary to grind the outer wall of the circular workpiece, the two clamping plates are used to tightly press against the inner wall of the workpiece, thereby completing the locking of the workpiece. When it is necessary to grind the inner wall of the circular workpiece, the two clamping plates are used to clamp the outer wall of the workpiece, thereby completing the locking of the workpiece and ensuring the grinding effect of the workpiece.

[0007] Preferably, each of the clamping plate members includes a collar, each collar is sleeved on a corresponding adjusting rod and rotatably connected to the adjusting rod, a support plate is fixedly connected to the adjusting rod, the adjusting member includes an adjusting motor fixedly connected to the support plate, a gear ring is coaxially and fixedly connected to the outer side wall of the collar, and a number of gears equal to the number of gear rings are coaxially and fixedly connected to the output shaft of the adjusting motor, and each gear meshes with a corresponding gear ring.

[0008] By adopting the above technical solution, when the adjusting motor is started, it can drive the gear fixed to the output shaft of the adjusting motor to rotate. Due to the meshing effect between the gear and the gear ring, the gear drives the gear ring to rotate, and the rotation of the gear ring causes the collar to rotate around the adjusting rod. This process realizes the precise angle adjustment of the clamping plate member, so as to facilitate adapting to the surfaces of workpieces of different sizes.

[0009] Preferably, each of the clamping plate members includes two collars, and further includes a locking plate. Threaded holes and guide holes are formed in the side wall of each locking plate close to the adjusting rod. Threaded rods are threadedly connected in each threaded hole, guide rods are slidably inserted in each guide hole, one end of each threaded rod away from the locking plate is rotatably connected to a corresponding collar, one end of each guide rod away from the locking plate is fixedly connected to a corresponding collar, and locking members for locking between the threaded rod and the corresponding collar are installed on each threaded rod.

[0010] By adopting the above technical solution, rotating the threaded rod can drive the locking plate to move towards or away from the adjusting rod, thereby adjusting the distance between the locking plate and the adjusting rod to adapt to workpieces of different sizes. At the same time, the arrangement of the guide rod effectively restricts the circumferential force generated when the threaded rod rotates from causing the position deviation of the locking plate, ensuring the smooth and reliable locking action. When there is no need to rotate the threaded rod, the threaded rod and the collar are locked by the locking member, reducing the occurrence of the situation where the threaded rod rotates due to accidental contact with the threaded rod.

[0011] Preferably, the locking member includes an adjusting block slidably connected to the corresponding threaded rod, the threaded rod passes through the adjusting block, a slider is fixedly connected to the inner side wall of the adjusting block, a sliding groove is formed in the side wall of the threaded rod, the slider is slidably inserted into the sliding groove, a plug block is fixedly connected to the side surface of the adjusting block close to the collar, and a plug slot is formed in the side wall of each collar connected to the threaded rod, and the plug block is tightly inserted into the corresponding plug slot.

[0012] By adopting the above technical solution, the quick locking and unlocking of the connection state between the threaded rod and the collar are realized. Specifically, when the insertion block is tightly inserted into the insertion groove, the accidental rotation of the threaded rod relative to the collar is effectively reduced, that is, the threaded rod is locked, improving the stability of the clamping plate during use. When it is necessary to rotate the threaded rod, move the adjusting block in the direction away from the collar until the insertion block on the adjusting block disengages from the insertion groove. During this process, the slider moves along the sliding groove. Then, rotate the adjusting block by hand or with the aid of a tool. When the adjusting block rotates, the threaded rod is driven to rotate by the slider, so that it is convenient to rotate the threaded rod to adjust the distance between the locking plate and the adjusting rod.

[0013] Preferably, the adjusting block is hexagonal prism-shaped.

[0014] By adopting the above technical solution, it is convenient to rotate the adjusting block with the aid of a tool, so as to rotate the threaded rod more smoothly.

[0015] Preferably, elastic layers are fixedly connected to both side walls of each locking plate.

[0016] By adopting the above technical solution, the elastic layers fixedly connected to both side walls of the locking plate can enhance the friction between the locking plate and the workpiece, thus enhancing the stability during clamping and reducing the displacement of the workpiece during the grinding process. The elastic layer has a certain buffering effect, which can reduce the damage to the workpiece caused by excessive clamping force and improve the quality and integrity of the workpiece surface. And the design of the elastic layer facilitates the elastic layer to better fit the shape of the inner and outer walls of the workpiece when the locking plate abuts against the inner and outer walls of the workpiece.

[0017] Preferably, a protective cover is detachably connected to the support plate. The bottom surface of the protective cover is open and the protective cover covers the adjusting member inside. Four arc-shaped holes are formed in the protective cover, and each arc-shaped hole is for inserting the threaded rod or the guide rod.

[0018] By adopting the above technical solution, the protective cover can effectively block external impurities from entering the working area of the adjusting member, reducing the influence of external factors such as dust and debris on components such as the adjusting motor, gears and gear rings, thereby improving the stability of the equipment operation and extending the service life. And the detachable design of the protective cover is convenient for regular cleaning and maintenance of the adjusting member, ensuring that the adjusting member maintains a good working state for a long time.

[0019] Preferably, the driving assembly includes two fixed blocks fixedly connected to the bottom surface of the working platform. A bidirectional lead screw is rotatably connected between the two fixed blocks. A connecting motor for driving the bidirectional lead screw to rotate is fixedly connected to one of the fixed blocks. A long strip hole is formed in the working platform, and each adjusting rod is slidably connected to the long strip hole. The lower end of each adjusting rod is threadedly connected to the bidirectional lead screw.

[0020] By adopting the above technical solution, during the working process, the connecting motor starts to drive the bidirectional lead screw to rotate. Since the lower end of the adjusting rod is threadedly connected to the bidirectional lead screw, and at the same time the adjusting rod is slidably matched with the working platform through the long strip hole, as the bidirectional lead screw rotates, the two adjusting rods can move towards or away from each other along the direction of the long strip hole. This design enables the workpiece to be accurately positioned at a suitable position for clamping and grinding.

[0021] Preferably, a plurality of support rods are fixedly connected to the upper surface of the working platform, and the upper ends of the plurality of support rods are fixedly connected to a top plate at the same time. The grinding mechanism includes a hydraulic cylinder I fixedly connected to the bottom surface of the top plate. The piston rod of the hydraulic cylinder I is vertically downward and fixedly connected to a transition plate. One surface of the transition plate is fixedly connected with two transition blocks. A transition lead screw is rotatably connected between the two transition blocks. One of the transition blocks is fixedly connected with a transition motor for driving the transition lead screw to rotate. A nut is threadedly connected to the transition lead screw, and a hydraulic cylinder II is fixedly connected to the nut. The piston rod of the hydraulic cylinder II is arranged perpendicular to the transition lead screw. A grinding stone is rotatably connected to the piston rod of the hydraulic cylinder II, and a rotating motor for driving the grinding stone to rotate is connected to the grinding stone.

[0022] By adopting the above technical solution, the multi-degree-of-freedom adjustment function of the grinding mechanism is realized. Specifically, the hydraulic cylinder I can drive the entire transition plate to move up and down, thereby adjusting the height position of the grinding stone; the setting of the transition lead screw, the nut and the transition motor enables the grinding stone to achieve precise position adjustment in the horizontal direction; the hydraulic cylinder II further provides an additional lateral displacement adjustment ability for the grinding stone to ensure that the grinding stone can flexibly approach or move away from different parts of the workpiece; and the rotating motor drives the grinding stone to rotate, which ensures the effective grinding treatment of the workpiece. This combined design greatly improves the adaptability of the equipment to workpieces of different sizes and shapes, and enhances the flexibility and efficiency of the grinding operation.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. When it is necessary to grind the outer wall of a circular workpiece, the inner wall of the workpiece is clamped by the two clamping plate members, thereby completing the locking of the workpiece. When it is necessary to grind the inner wall of a circular workpiece, the outer wall of the workpiece is clamped by the two clamping plate members, thereby completing the locking of the workpiece, ensuring the grinding effect of the workpiece; 2. The two clamping plate members on each adjusting rod can be rotationally controlled through the adjusting member, so that the clamping plate members can accurately fit the outer wall or the inner wall of the workpiece, thereby improving the clamping accuracy and stability; 3. It is convenient to rotate the threaded rod to adjust the distance between the locking plate and the adjusting rod. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0029] The following further describes the present application in detail with reference to the Figures 1-4 accompanying drawings.

[0030] Embodiments of the present application disclose a workpiece grinding equipment. Referring to Figure 1 and Figure 2 , it includes a working platform 1 and a locking mechanism 2 installed on the working platform 1. A support frame for supporting the working platform 1 is fixedly connected to the bottom surface of the working platform 1, and the locking mechanism 2 is used to lock the workpiece. Four support rods 11 are fixedly connected to the working platform 1, each support rod 11 is located at the corner of the working platform 1, and the upper ends of each support rod 11 are commonly fixedly connected to the same top plate 12. A grinding mechanism 3 for grinding the workpiece is installed on the bottom surface of the top plate 12.

[0031] The grinding mechanism 3 includes a hydraulic cylinder 31 fixedly connected to the bottom surface of the top plate 12. The piston rod of the hydraulic cylinder 31 is vertically downward and fixedly connected with a transition plate 32, and the transition plate 32 is horizontally arranged. Two transition blocks 321 are fixedly connected to the lower surface of the transition plate 32. The two transition blocks 321 are distributed along the length direction of the transition plate 32, and a transition lead screw 322 is rotatably connected between the two transition blocks 321. A transition motor 323 is fixedly connected to the side wall of one of the transition blocks 321 facing away from the transition lead screw 322. The output shaft of the transition motor 323 penetrates through the corresponding transition plate 32 and is fixedly connected to the transition lead screw 322 coaxially. A nut 324 is threadedly connected to the transition lead screw 322.

[0032] Refer to Figure 1 and Figure 2 , a hydraulic cylinder 325 is fixedly connected to the bottom surface of the nut 324. The piston rod of the hydraulic cylinder 325 is horizontally arranged perpendicular to the transition lead screw 322. A placement block 326 is fixedly connected to the piston rod of the hydraulic cylinder 325. A grinding stone 327 is rotatably connected to the bottom surface of the placement block 326. A rotation motor 328 is fixedly connected to the upper surface of the placement block 326. The output shaft of the rotation motor 328 penetrates through the placement block 326 and is fixedly connected to the grinding stone 327 coaxially.

[0033] Start the hydraulic cylinder 31, and the piston rod of the hydraulic cylinder 31 expands and contracts to drive the grinding stone 327 to move vertically up and down. Start the transition motor 323, and the output shaft of the transition motor 323 rotates to drive the transition lead screw 322 to rotate. In this way, the nut 324 drives the hydraulic cylinder 325, the placement block 326 and the grinding stone 327 to move along the length direction of the transition lead screw 322, so as to adjust the horizontal position of the grinding stone 327. Start the hydraulic cylinder 325, and the piston rod of the hydraulic cylinder 325 drives the placement block 326 and the grinding stone 327 to move horizontally, which is also convenient for adjusting the position of the grinding stone 327. When the grinding stone 327 grinds the inner and outer walls of the workpiece, start the rotation motor 328, and the output shaft of the rotation motor 328 drives the grinding stone 327 to rotate to grind the workpiece.

[0034] Refer to Figure 2 and Figure 3 , the locking mechanism 2 includes two adjusting rods 21 slidably connected to the working platform 1 and a driving assembly 22 for driving the two adjusting rods 21 to move towards or away from each other. Two clamping plate members 23 are rotatably connected to each adjusting rod 21. The adjusting rod 21 is located between the two clamping plate members 23. An adjusting member 24 for driving the two clamping plate members 23 to rotate towards or away from each other is also installed on each adjusting rod 21. Each clamping plate member 23 is used to abut against the outer side wall or the inner side wall of the workpiece, improving the clamping adaptability to workpieces of different specifications and shapes.

[0035] Refer to Figure 1 and Figure 2, a long hole 13 penetrating through the working platform 1 is formed on the upper surface of the working platform 1, and the lower end of each adjusting rod 21 is slidably inserted into the long hole 13. The driving assembly 22 includes two fixing blocks 221 fixedly connected to the bottom surface of the working platform 1. The long hole 13 is located between the two fixing blocks 221. A bidirectional lead screw 222 is rotatably connected between the two fixing blocks 221, and the bidirectional lead screw 222 is arranged along the length direction of the long hole 13. The lower end of each adjusting rod 21 is fixedly connected with a connecting block. The bidirectional lead screw 222 penetrates through each connecting block and is threadedly connected with the connecting block. A connecting motor 223 is fixedly connected to one of the fixing blocks 221, and the output shaft of the connecting motor 223 is coaxially fixed to one end of the bidirectional lead screw 222.

[0036] Start the bidirectional lead screw 222, and the bidirectional lead screw 222 rotates to drive the two adjusting rods 21 to move towards each other or away from each other. The movement of the two adjusting rods 21 drives each clamping plate 23 to press against the inner wall or the outer wall of the workpiece.

[0037] Refer to Figure 3 and Figure 4 , each clamping plate 23 includes two collars 231 and a locking plate 232. Each collar 231 is sleeved on the outside of the adjusting rod 21 and has a stable rotational connection relationship with the adjusting rod 21. A threaded hole 2321 and a guiding hole 2322 are formed on one side wall of each locking plate 232 close to the adjusting rod 21. The threaded hole 2321 and the guiding hole 2322 are arranged vertically. A threaded rod 233 is threadedly connected in each threaded hole 2321, and a guiding rod 234 is slidably inserted into each guiding hole 2322. One end of each threaded rod 233 away from the locking plate 232 is rotatably connected to the outer wall of one of the collars 231, and one end of each guiding rod 234 away from the locking plate 232 is fixedly connected to the outer wall of the other collar 231. A locking member 25 for locking between the threaded rod 233 and the corresponding collar 231 is installed on each threaded rod 233.

[0038] By adjusting the locking of the locking member 25 to release the locking between the threaded rod 233 and the corresponding collar 231, and then rotating the threaded rod 233, the rotation of the threaded rod 233 adjusts the locking plate 232 to move towards or away from the adjusting rod 21, so as to facilitate adjusting the distance between the locking plate 232 and the adjusting rod 21, and further facilitate locking workpieces with different diameters.

[0039] Refer to Figure 2 and Figure 3, a support plate 4 is fixedly connected to the lower end of each adjusting rod 21. The adjusting member 24 includes two adjusting motors 241 fixedly connected to the support plate 4. A gear ring 242 is coaxially and fixedly connected to the outer side wall of each collar 231 connected with a guide rod 234. The output shaft of each adjusting motor 241 is vertically upward and coaxially fixedly connected with a gear 243. One gear 243 corresponds to one gear ring 242, and the gear 243 meshes with the gear ring 242.

[0040] When the two adjusting motors 241 are started simultaneously, the output shaft of each adjusting motor 241 drives the gear 243 to rotate. The rotation of the gear 243 drives the gear ring 242 and the collar 231 to rotate. In this way, it is convenient to adjust the two locking plates 232 to rotate towards each other or away from each other, so as to clamp workpieces with different diameters.

[0041] Refer to Figure 3 and Figure 4 , the locking member 25 includes an adjusting block 251 slidably connected to each threaded rod 233. A sliding groove 2331 is formed in the side wall of each threaded rod 233. The adjusting block 251 is penetrated by the threaded rod 233. A slider 252 is fixedly connected to the inner side wall of the adjusting block 251, and the slider 252 is slidably connected to the sliding groove 2331. Two insertion blocks 253 are fixedly connected to the side wall of the adjusting block 251 close to the collar 231. Two insertion slots 2311 are formed in the outer side wall of each collar 231 connected with the threaded rod 233. One insertion block 253 corresponds to one insertion slot 2311, and the insertion block 253 is tightly inserted into the insertion slot 2311.

[0042] The outer shape of the adjusting block 251 is a regular hexagonal cross-section column. When it is necessary to adjust the distance between the locking plate 232 and the adjusting rod 21, the adjusting block 251 is moved in a direction away from the collar 231 until each insertion block 253 disengages from the corresponding insertion slot 2311. At this time, the adjusting block 251 is rotated by means of a tool. The rotation of the adjusting block 251 drives the threaded rod 233 to rotate through the slider 252, and the rotation of the threaded rod 233 can drive the locking plate 232 to move towards or away from the adjusting rod 21.

[0043] Refer to Figure 2 and Figure 3 , elastic layers 5 are fixedly connected to both side walls of the locking plate 232, so that each side wall of the locking plate 232 can better abut against the inner side wall or the outer side wall of the workpiece.

[0044] A protective cover 6 is detachably connected to the support plate 4. The bottom surface of the protective cover 6 is open, and the bottom surface of the protective cover 6 abuts against the upper surface of the support plate 4. The protective cover 6 covers the adjusting member 24 inside. The top surface of the protective cover 6 is fixedly connected to the upper end of the adjusting rod 21 by screws. Four arc-shaped holes 61 are formed in the side wall of the protective cover 6, and a threaded rod 233 or a guide rod 234 is inserted into each arc-shaped hole 61. The arrangement of the arc-shaped rod facilitates the relatively smooth rotation of the clamping plate 23 relative to the adjusting rod 21.

[0045] The implementation principle of a workpiece grinding device according to an embodiment of the present application is as follows: When it is necessary to grind the outer side wall of a workpiece, the adjusting rod 21 is placed inside the workpiece, and then the driving assembly 22 is started to drive the two adjusting rods 21 to move away from each other until one side wall of each locking plate 232 abuts against the inner side wall of the workpiece, so that the workpiece is locked, facilitating the grinding of the outer side wall of the workpiece. When it is necessary to grind the inner side wall of the workpiece, the workpiece is controlled to be located between the two adjusting rods 21, and then the driving assembly 22 is started to drive the two adjusting rods 21 to move closer to each other until one side wall of each locking plate 232 abuts against the outer side wall of the workpiece, so that the workpiece is locked, facilitating the grinding of the inner side wall of the workpiece.

[0046] The above are all the preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: Any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
