Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of grinding equipment, specifically, it relates to a precision grinding device. Background Technology
[0002] The production process of a part refers to the entire process from raw materials to finished products. During the processing, parts need to undergo processes such as grinding to produce a complete part.
[0003] Chinese patent application CN202323414932.4 discloses a precision grinding device for mechanical parts, including a support table assembly and a grinding assembly. The support table assembly includes a hydraulic cylinder, one end of which is fixedly connected to a table plate. A ring plate is fixedly connected to the outer wall of the table plate, and a screw is threadedly connected to the inner wall of the ring plate. One end of the screw is fixedly connected to a ball bearing. Multiple screws and balls are arranged in a ring on the inner wall of the ring plate. The grinding assembly includes an upper support, with a first grinding mechanism and a second grinding mechanism arranged on the inner wall of the upper support. Although this device uses the support table assembly to rotate the screws to adjust the position of the balls, thus fixing parts of different specifications and shapes, in actual use, multiple screws need to be rotated separately to adjust the positions of multiple balls, so that each ball abuts against different surfaces of the part for fixing. This fixing method is slow, and fixing and removing parts is cumbersome. Furthermore, the circular array of multiple screws requires the operator to move to the corresponding screw position to rotate it.
[0004] In view of this, this utility model is hereby proposed. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a precision grinding device.
[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 precision grinding device includes a base, an upper support mounted on the base, a grinding assembly disposed inside the upper support, a hydraulic cylinder mounted on the top of the base, and a support platform mounted on the output end of the hydraulic cylinder.
[0008] The top of the support platform is equipped with a fixed ring plate, and multiple fixed cylinders are installed around the periphery of the fixed ring plate. The multiple fixed cylinders are arranged in a circumferential array. A sliding rod is slidably fitted inside the fixed cylinder. An adjustment component is set between the fixed cylinder and the sliding rod. A sleeve is elastically fitted at one end of the sliding rod. A rotating ring is rotatably fitted on the top of the support platform. A gear plate is installed around the inner wall of the rotating ring. The gear plate meshes with multiple adjustment components. A movable ring is slidably fitted inside the fixed ring plate and engages with multiple sleeves. Fixed rods are installed on both sides of the movable ring and engage with the gear plate.
[0009] Optionally, the adjusting assembly includes a lead screw rotatably fitted inside a fixed cylinder, a gear mounted at one end of the lead screw, the gear meshing with a gear plate, and the lead screw threadedly fitted with a slide bar.
[0010] Optionally, the bottom of the moving ring is provided with multiple fixing grooves corresponding to multiple sleeves, and friction blocks are installed in the fixing grooves. Two connecting blocks are installed on both sides of the top of the moving ring, and fixing bolts are provided between the connecting blocks and the fixing ring plate.
[0011] Optionally, the fixing rod is L-shaped, and a locking block is provided at one end of the fixing rod that passes through the fixing ring plate. The locking block engages with the gear plate.
[0012] Optionally, the grinding assembly includes a first grinding mechanism mounted on the bottom of the inner wall of the upper support and a second grinding mechanism slidably fitted on one side of the inner wall of the upper support.
[0013] Optionally, the upper support is L-shaped, with a mounting plate installed on one side of the inner wall of the upper support, an electric push rod installed on one side of the mounting plate, a sliding groove opened on one side of the inner wall of the upper support, a slider slidingly fitted in the sliding groove, the output end of the electric push rod connected to one side of the slider, and the second grinding mechanism installed on one side of the slider.

[0016] 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:
[0017] The adjustable components allow the rotating ring to drive the gear disc, activating multiple adjustable components. These components then move the sliding rods, which in turn move the sliding rods to press against different surfaces of the workpiece via multiple sleeves. This secures the workpiece, facilitating its fixation and removal, reducing the need for workers to move the workpiece, and enabling more precise machining. The sliding rods move the sleeves, pressing them against the workpiece. After the sleeves are in contact with the workpiece, further movement of the sliding rod causes the sleeves to elastically contract, accommodating workpieces of different sizes and shapes. A movable ring allows for movement, securing multiple sleeves and preventing elastic contraction, ensuring stable fixation of the workpiece.

Detailed Implementation
[0027] The present invention will now be described in further detail with reference to the accompanying drawings.
[0028] Please see Figure 1-4 As shown, this embodiment provides a precision grinding device, including a base 1, an upper support 2 mounted on the base 1, a grinding assembly 3 disposed inside the upper support 2, a hydraulic cylinder 4 mounted on the top of the base 1, and a support platform 5 mounted on the output end of the hydraulic cylinder 4.
[0029] The top of the support platform 5 is equipped with a fixed ring plate 6, and multiple fixed cylinders 7 are installed around the periphery of the fixed ring plate 6. The multiple fixed cylinders 7 are arranged in a circular array. A sliding rod 8 is slidably fitted inside the fixed cylinder 7. An adjustment component 9 is provided between the fixed cylinder 7 and the sliding rod 8. A sleeve 10 is elastically fitted at one end of the sliding rod 8. A rotating ring 11 is rotatably fitted on the top of the support platform 5. A gear plate 12 is installed around the inner wall of the rotating ring 11. The gear plate 12 meshes with multiple adjustment components 9 respectively. A movable ring 13 is slidably fitted inside the fixed ring plate 6 and engages with multiple sleeves 10. Fixed rods 14 are installed on both sides of the movable ring 13 and engage with the gear plate 12.
[0030] One application of this embodiment is as follows: In use, the part is placed on the support platform 5, so that the part is located within the fixed ring plate 6. Then, the rotating ring 11 is rotated, causing the rotating ring 11 to drive the gear plate 12 to rotate. The rotation of the gear plate 12 will activate multiple adjusting components 9, causing the adjusting components 9 to drive the sliding rods 8 to move, so that the sliding rods 8 move out of the fixed cylinder 7. The movement of the sliding rods 8 will drive the sleeve 10 to move, so that the sleeve 10 abuts against the part. According to the shape of the part, the sleeve 10 that abuts against the part will elastically contract first. Then, the multiple sliding rods 8 continue to move until all the parts are in contact with the part. The sleeve 10 presses against the part to initially fix it. Then, the moving ring 13 is adjusted to fix and limit the multiple sleeves 10, preventing the sleeves 10 from elastically contracting and completely fixing the part. This facilitates subsequent precision machining of the part. Then, the grinding assembly 3 is adjusted to grind the part. After machining, the moving ring 13 is adjusted to contact the fixing and limiting of the multiple sleeves 10. Then, the rotating ring 11 is adjusted to rotate in the opposite direction, causing the gear plate 12 to adjust the multiple adjusting assemblies 9, so that the slide rod 8 moves and retracts into the fixed cylinder 7, releasing the fixation of the part.
[0031] The adjustable components 9 can rotate the ring 11 to drive the gear plate 12 to rotate, thereby adjusting multiple adjustable components 9. These components drive the sliding rods 8 to move, allowing the sliding rods 8 to abut against different surfaces of the parts via multiple sleeves 10, thus fixing the parts. This facilitates fixing and removing the parts, reduces the need for workers to move to fix them, and enables more precise machining. The sliding rods 8 move the sleeves 10, causing them to abut against the parts. After the sleeves 10 abut against the parts, further movement of the sliding rods 8 causes the sleeves 10 to elastically contract, adapting to parts of different sizes and shapes. The movable ring 13 can be moved to fix the multiple sleeves 10, preventing elastic contraction and ensuring stable fixation of the parts.
[0032] like Figure 3As shown, the adjustment assembly 9 in this embodiment includes a lead screw 901 rotatably fitted inside the fixed cylinder 7 and a gear 902 mounted on one end of the lead screw 901. The gear 902 meshes with the gear disc 12, and the lead screw 901 is threadedly fitted with the slide rod 8. By adjusting the rotation of the rotating ring 11 through the gear 902, the gear disc 12 can be rotated. The rotation of the gear disc 12 will drive multiple gears 902 to rotate, causing the gears 902 to drive the lead screw 901 to rotate. The rotation of the lead screw 901 will drive the slide rod 8 to move, causing the slide rod 8 to move the sleeve 10 to abut against the part.
[0033] like Figure 4 As shown, in this embodiment, the bottom of the movable ring 13 is provided with multiple fixing grooves 15 corresponding to multiple sleeves 10. Friction blocks 16 are installed in the fixing grooves 15. Two connecting blocks 17 are installed on both sides of the top of the movable ring 13. Fixing bolts 18 are provided between the connecting blocks 17 and the fixing ring plate 6. Through the fixed grooves 15, the fixing bolts 18 can be moved to drive the movable ring 13 downward, so that the sleeves 10 enter the corresponding fixing grooves 15. The friction blocks 16 in the fixing grooves 15 will fix the sleeves 10, so that the movable ring 13 fixes the multiple sleeves 10.
[0034] A spring 27 is installed between one end of the slide rod 8 and the inside of the sleeve 10. The sleeve 10 is slidably fitted in the fixed cylinder 7 through the slide rod 8. A square groove is opened in the fixed cylinder 7 to limit the sleeve 10. The sleeve 10 limits the slide rod 8 so that the sleeve 10 and the slide rod 8 will not rotate.
[0035] like Figure 4 As shown, the fixing rod 14 in this embodiment is L-shaped. A locking block 19 is provided at one end of the fixing rod 14 that passes through the fixing ring plate 6. The locking block 19 engages with the gear disc 12. Through the locking block 19, while the moving ring 13 moves downward to fix multiple sleeves 10, it also drives the fixing rod 14 to move, causing the fixing rod 14 to move the locking block 19. The locking block 19 engages with the gear disc 12, fixing the gear disc 12 and preventing it from rotating during processing.
[0036] like Figure 2As shown, the grinding assembly 3 in this embodiment includes a first grinding mechanism 301 mounted on the bottom of the inner wall of the upper support 2 and a second grinding mechanism 302 slidably fitted on one side of the inner wall of the upper support 2. The upper support 2 is L-shaped, with a mounting plate 20 mounted on one side of the inner wall of the upper support 2. An electric push rod 21 is mounted on one side of the mounting plate 20. A sliding groove 22 is formed on one side of the inner wall of the upper support 2, and a slider 23 is slidably fitted in the sliding groove 22. The output end of the electric push rod 21 is connected to one side of the slider 23, and the second grinding mechanism 302 is mounted on one side of the slider 23. By using the electric push rod 21, the slider 23 can be moved. The slider 23 moves stably left and right along the sliding groove 22, causing the slider 23 to move the second grinding mechanism 302. The position of the second grinding mechanism 302 is adjusted, allowing the first grinding mechanism 301 and the second grinding mechanism 302 to perform grinding processing on the parts.
[0037] like Figure 3 As shown, the rotating ring 11 in this embodiment is equipped with multiple handles 24 on its circumference, and the multiple handles 24 are arranged in a circular array. By pulling the handles 24, the rotating ring 11 can be rotated, so that the rotating ring 11 drives the gear plate 12 to adjust the adjustment component 9. The multiple handles 24 arranged in a circular array make it convenient for the operator to adjust the rotating ring 11 at any position.
[0038] like Figure 1 As shown, in this embodiment, the base 1 has multiple mounting slots 25 on both outer sides, and mounting holes 26 are provided at the bottom of the mounting slots 25. Through the mounting holes 26, the base 1 can be installed and fixed in a suitable position.
