Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically a high-precision grinding structure for correcting errors in parts. Background Technology

[0002] In fields such as precision machinery, optoelectronics, and semiconductors, the flatness, parallelism, and thickness tolerance requirements for sheet-like components (such as silicon wafers, ceramic substrates, precision gaskets, and valve plates) are extremely stringent. Microscopic errors in these components directly affect the performance, efficiency, and lifespan of the entire equipment or system. Therefore, in high-precision machining processes, a grinding process is typically required to correct their shape and dimensional errors. Currently, single-sided grinding machines are commonly used for the planar grinding of such sheet-like workpieces. The typical working method involves placing the workpiece on a grinding disc via planetary gears or a fixed fixture. The grinding disc rotates, driving the workpiece to move. Pressure is applied through an upper pressure plate or a single pressure head, causing relative movement between the workpiece surface and the abrasive, thereby achieving the grinding effect.

[0003] In traditional planetary gear structures, although the workpiece revolves and rotates, its trajectory is relatively fixed. This easily leads to repetitive and periodic grinding paths in the contact area between the workpiece surface and the grinding disc. This results in uneven material removal rates on the workpiece surface, making it difficult to achieve extremely high surface accuracy, and easily causing edge collapse or curling at the workpiece edges. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision grinding structure for correcting component errors, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A grinding structure includes a grinding disc, a turntable is rotatably mounted inside the grinding disc, and abrasive is fixedly mounted on the upper surface of the turntable;

[0008] The limiting structure includes a limiting box, which is arranged in a ring at equal angles and is suspended and rotated on the inner edge of the grinding disc. A limiting slot is provided at the bottom of the limiting box.

[0009] The pressure-applying structure includes a screw cap that is snapped onto an opening on a grinding disc, and a pressure plate that is rotatably mounted on the bottom of the screw cap.

[0010] Furthermore, the inner wall of the grinding disc is provided with a slot for inserting a plate.

[0011] Furthermore, the bottom of the turntable is fixedly connected to an internal gear ring, the bottom of the grinding disc is rotatably mounted with a transmission gear that meshes with the internal gear ring, a transmission platform is rotatably mounted in the middle of the grinding disc, a first external gear ring that meshes with the transmission gear is fixedly sleeved on the lower side surface of the transmission platform, and a second external gear ring is fixedly sleeved on the upper side surface of the transmission platform.

[0014] Furthermore, the limiting box is rotatably installed on one end of the plate frame, and an installation insert is fixedly installed on one side of the plate frame, with the installation insert being inserted into the insert slot.

[0015] Furthermore, the inner top edge of the cap is fixedly equipped with several sets of pressure strips arranged in a ring at equal angles, which engage with the insert slots.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 In this embodiment of the present invention, a high-precision grinding structure for correcting component errors includes a grinding structure 1, a limiting structure 2, and a pressure applying structure 3. The grinding structure 1 includes a grinding disc 101, a turntable 104 is rotatably mounted inside the grinding disc 101, and an abrasive 105 is fixedly mounted on the upper surface of the turntable 104. The limiting structure 2 includes a limiting box 203, which is arranged in a ring at equal angles and is rotatably mounted on the inner edge of the grinding disc 101. A limiting slot 204 is inserted into the bottom of the limiting box 203. The pressure applying structure 3 includes a cap 301, which is snapped into the opening on the grinding disc 101. A pressure plate 307 is rotatably mounted on the bottom of the cap 301.

[0027] Specifically, the grinding structure 1 is fixedly installed on the worktable surface, and the limiting structure 2 is fixedly installed at the lower end of the lifting structure. First, the sheet-like workpiece to be ground is inserted into the limiting slot 204 at the bottom of the limiting box 203. Then, the screw cap 301 is lowered and engages with the opening on the grinding disc 101, so that each pressure plate 307 is inserted into the limiting box 203 and pressure is applied, so that the workpiece to be ground is in close contact with the abrasive 105. The rotating grinding disc 101 drives the abrasive 105 to grind the bottom of the workpiece. At the same time, the limiting box 203 rotates synchronously, further enhancing the grinding efficiency. At the same time, the contact position between the bottom of the workpiece and the bottom of the abrasive 105 is constantly changed to improve the grinding uniformity.

[0028] Example 1

[0029] like Figure 1-3 As shown, in this embodiment, the inner wall of the grinding disc 101 is provided with a insert slot 103; the limiting box 203 is rotatably installed on one end of the disc frame 202, and an installation insert 201 is fixedly installed on one side of the disc frame 202, and the installation insert 201 is inserted into the insert slot 103.

[0030] In this embodiment, by inserting the mounting plate 201 into the mounting plate slot 103, each limiting box 203 is suspended and installed in the air. The other side is supported by the lower edge of the transmission table 109, which ensures the stability of the limiting box 203 during operation. At the same time, the overall structure is easy to disassemble and replace. The limiting box 203 with different shaped limiting slots 204 can be replaced according to the shape of the workpiece being processed, thereby improving the production range.

[0031] like Figure 3-5 As shown, in this embodiment, several sets of pressure strips 302 that engage with the insert slot 103 are fixedly installed in a ring-shaped, equidistant arrangement on the inner top edge of the cap 301. Several mounting seats 303 are fixedly installed in a ring-shaped, equidistant arrangement on the inner top edge of the cap 301. A spring telescopic rod 304 is fixedly installed at the bottom of the mounting seat 303. A pressure sensor 305 is fixedly installed at the lower output end of the spring telescopic rod 304. A rotating seat 306 is fixedly installed at the lower end of the pressure sensor 305. A pressure plate 307 is rotatably installed at the bottom of the rotating seat 306 via a bearing.

[0032] In practice, after the workpiece is inserted into the limiting slot 204, the pressure plate 307 is inserted into the slot under the action of the spring telescopic rod 304, applying vertical pressure to make the workpiece adhere tightly to the abrasive 105. This design prevents the workpiece from shifting or lifting during the grinding process, ensuring a flat grinding surface. The pressure sensor 305 monitors the applied pressure in real time, and the spring telescopic rod 304 provides buffering and adaptive pressure adjustment to avoid excessive pressure causing workpiece deformation or insufficient pressure affecting grinding efficiency. It is suitable for thin sheet-like workpieces and can effectively prevent breakage or bending.

[0033] Example 2

[0034] Based on Embodiment 1, in order to supplement the specific transmission structure of the overall structure not mentioned in Embodiment 1, the specific method of synchronously rotating the turntable 104 and the limiting box 203 is described.

[0035] like Figure 2-3 As shown, in this embodiment, an internal gear ring 106 is fixedly connected to the bottom of the turntable 104, a transmission gear 107 that meshes with the internal gear ring 106 is rotatably mounted on the bottom of the grinding disc 101, a transmission platform 109 is rotatably mounted in the middle of the grinding disc 101, a first external gear ring 108 that meshes with the transmission gear 107 is fixedly sleeved on the lower side surface of the transmission platform 109, and a second external gear ring 110 is fixedly sleeved on the upper side surface of the transmission platform 109; a connecting bridge 111 is fixedly mounted on the bottom of the grinding disc 101, the internal gear ring 106 is rotatably mounted inside the connecting bridge 111, a bottom box 112 is fixedly mounted on the bottom of the connecting bridge 111, a drive motor 113 is fixedly mounted inside the bottom of the bottom box 112, and the output end of the drive motor 113 is fixedly connected to the transmission platform 109.

[0036] In practice, the drive motor 113 drives the transmission table 109 to rotate, and the transmission structure of the first external gear ring 108, the transmission gear 107 and the internal gear ring 106 drives the turntable 104 to rotate. At the same time, the second external gear ring 110 rubs each third external gear ring 205, and the rotation of each limit box 203 is controlled synchronously to carry out the grinding work.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
