The clamping device comprises a fixed clamping plate and a movable clamping plate which are used for clamping the false tooth. After the fixed clamping plate and the movable clamping plate clamp a blank, the clamping block is attached to the clamping groove, so that the movable clamping plate is not prone to being away from the fixed clamping plate, and then it is guaranteed that the clamping force of the fixed clamping plate and the movable clamping plate to the blank cannot be reduced; the clamping force of a fixed clamping plate and a movable clamping plate on a blank is reduced, so that the blank is loosened after being machined, and when clamping teeth at the upper end of a clamping block cannot move into a next clamping groove, a nut is rotated and matched with the fixed clamping plate to extrude a spring, so that the spring pushes the nut, and the movable clamping plate gradually gets close to the direction of the fixed clamping plate; and therefore, the blank is clamped.

Description

Technical Field

[0001] The utility model relates to the technical field of denture processing, in particular to a fixture of a denture cutting machine. Background Art

[0002] During the production and processing of removable dentures, the blank must be firmly clamped by a fixture before cutting or carving tools can be used for processing.

[0003] For example, a fixed denture cutting fixture disclosed in Chinese patent application number CN202323347343.9 has the following specific contents: the blank is placed on the base, one end of the blank is fitted with the fixed clamping plate, the pressing block is pushed to move, and the inclined surface on the pressing block pushes the clamping plate to move to both sides. Due to the squeezing of the clamping plate fixing ring, the return spring is compressed, and the compressed return spring will generate elastic force to push the clamping plate inward to clamp. Because the push of the return spring causes the clamping plate to enter the groove on the pressing block in turn, thereby preventing the pressing block from retreating until the pressing block drives the movable clamping plate to fit the blank. At this time, the movable clamping plate and the fixed clamping plate fix the bottom end position of the blank. When the bottom end of the blank is fixed, the pin is inserted. After the pin slides into the movable clamping plate and the fixed clamping plate, the rotating buckle on the base rotates, and the rotating buckle clamps the pin. The movement of the fixed column pin thereby produces a secondary fixation for the movable clamping plate. It has the following technical problems:

[0004] When cutting the blank, the blank is prone to vibration. After long-term use, the side of the fixture that clamps the blank will wear out, making it difficult to clamp the blank. When processing the denture blank, the blank will shake. In severe cases, the blank will directly fall out of the fixture, causing the blank to be scrapped. Utility Model Content

[0005] In order to solve the problem of the clamp's reduced clamping force on the blank after long-term use, the present invention provides the following technical solutions:

[0006] A denture cutting machine fixture includes a clamping device;

[0007] The clamping device comprises a fixed clamping plate and a movable clamping plate for clamping the denture.

[0008] A supporting device for supporting the clamping device is installed at the lower end of the clamping device, and the supporting device includes a supporting seat. The middle part of the support seat is processed with a sliding groove for sliding the movable splint, and the lower end of the groove cavity of the sliding groove is installed with a limiting component for limiting the movable splint.

[0009] A first screw is installed at both ends of the movable splint, a spring is sleeved on the outside of the first screw, and a nut is installed at one end of the first screw for cooperating with the spring to adjust the clamping force of the movable splint.

[0010] Furthermore, a mounting plate is installed at the lower end of the fixing splint for cooperating with the support seat to fix the fixing splint.

[0011] Furthermore, a limiting slider is installed at the lower end of the movable splint, a threaded hole is provided in the middle of the limiting slider, and a plurality of slots are provided at the lower end of the limiting slider, and one side of the slots is an inclined surface.

[0012] Furthermore, a mounting groove for limiting the mounting plate is processed on the upper end of the support seat, and a bolt for locking the fixed splint is installed at one end of the mounting groove.

[0013] Furthermore, the limiting assembly includes a card block, a connecting rod is installed at the lower end of the card block, a pulling block is installed at the lower end of the connecting rod, and a tension spring is sleeved on the outer side of the connecting rod for controlling the upward movement of the card block.

[0014] Furthermore, a limiting device is installed at one end of the supporting device, and the limiting device includes a sealing plate, a pull rod is installed in the middle of the sealing plate, and a second screw is installed at one end of the pull rod for cooperating with the threaded hole to limit the movable splint.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] After the fixed splint and the movable splint clamp the blank, the clamping block and the slot fit together, making it difficult for the movable splint to move away from the fixed splint, thereby ensuring that the clamping force of the fixed splint and the movable splint on the blank will not decrease. When the fixed splint and the movable splint are worn due to long-term use, the clamping force of the fixed splint and the movable splint on the blank will decrease, causing the blank to loosen after processing, and the teeth on the upper end of the clamping block cannot move to the next slot. By rotating the nut and cooperating with the fixed splint to squeeze the spring, the spring pushes the nut, and the movable splint gradually approaches the fixed splint to clamp the blank.

[0029] The following describes in detail the preferred specific implementation methods of the present invention, and makes a clear and complete description in conjunction with the accompanying drawings.

[0030] See also Figure 1-Figure 5 The utility model provides a denture cutting machine fixture, including a clamping device 001.

[0031] The clamping device 001 includes a fixed splint 100 and a movable splint 200 for clamping the denture, and two mounting plates 110 are fixedly mounted on the lower end of the fixed splint 100 .

[0032] The two ends of the movable splint 200 are fixedly installed with a first screw 210, and the outer sleeve of the first screw 210 is provided with a spring 211. One end of the first screw 210 is installed with a nut 212 for cooperating with the spring 211 to adjust the clamping force of the movable splint 200. When the fixed splint 100 and the movable splint 200 clamp the blank, the spring 211 is rotated to drive the movable splint 200 to gradually approach the fixed splint 100, thereby tightening the blank between the fixed splint 100 and the movable splint 200.

[0033] Three limiting sliders 220 are fixedly installed at the lower end of the movable splint 200. A threaded hole 221 is opened in the middle of the limiting slider 220. A plurality of slots 222 are opened at the lower end of the limiting slider 220 in the middle, and one side of the slot 222 is an inclined surface.

[0034] The lower end of the clamping device 001 is equipped with a supporting device 002 for supporting the clamping device 001, and the supporting device 002 includes a supporting seat 300, and the middle part of the supporting seat 300 is processed with a sliding groove 320 for the movable splint 200 to slide. There are three sliding grooves 320. The setting of the sliding grooves 320 facilitates the disassembly of the movable splint 200. When the end of the movable splint 200 facing the fixed splint 100 is severely worn and it is difficult to clamp the blank, the movable splint 200 can be disassembled and replaced with a new movable splint 200 to facilitate clamping the blank, so that it is more stable when processing the blank.

[0035] The upper end of the support seat 300 is processed with a mounting groove 310 for limiting the mounting plate 110, and two mounting grooves 310 are synchronously provided. The mounting plate 110 can be inserted into the groove cavity of the mounting groove 310. One end of the mounting groove 310 is installed with a bolt 311 for locking the fixed clamping plate 100. The middle part of the mounting plate 110 is processed with a hole cavity for inserting the bolt 311. When the mounting plate 110 is inserted into the hole cavity of the mounting groove 310, the bolt 311 passes through the middle hole of the mounting plate 110, The bolt 311 is screwed into the threaded hole opened on the support seat 300, thereby locking the mounting plate 110 to achieve the purpose of fixing the fixed splint 100. When the end of the fixed splint 100 facing the movable splint 200 is severely worn and needs to be replaced, the bolt 311 can be removed to pull the mounting plate 110 out of the groove cavity of the mounting groove 310 and replace it with a new fixed splint 100, so that the fixed splint 100 cooperates with the movable splint 200 to clamp the blank together, so as to facilitate the processing of the blank.

[0036] The locking cam 331 is fixed to the workpiece by the locking cam 332, and the locking cam 333 is fixed to the workpiece by the locking cam 332. The tightening force will not decrease. When the fixed splint 100 and the movable splint 200 are worn due to long-term use, the clamping force of the fixed splint 100 and the movable splint 200 on the blank will decrease, causing the blank to become loose after processing, and the teeth on the upper end of the block 331 cannot move to the next slot 222. By rotating the nut 212 and cooperating with the fixed splint 100 to squeeze the spring 211, the spring 211 pushes the nut 212, and the movable splint 200 gradually approaches the fixed splint 100 to clamp the blank.

[0037] A connecting rod 332 is fixedly mounted on the lower end of the clamping block 331. A pull block 333 is fixedly mounted on the lower end of the connecting rod 332. A tension spring 334 is sleeved on the outer portion of the connecting rod 332 to control the upward movement of the clamping block 331. The pull block 333 and the tension spring 334 are located at the bottom of the support base 300. One end of the tension spring 334 is fixedly connected to the upper end of the pull block 333, and the other end of the tension spring 334 is fixedly connected to the bottom wall of the support base 300.

[0038] A limiting device 003 is mounted on one end of the support device 002. The limiting device 003 includes a sealing plate 400. A pull rod 410 is mounted in the middle of the sealing plate 400. A second screw 411 is mounted on one end of the pull rod 410, which is used to cooperate with the threaded hole 221 to limit the position of the movable clamping plate 200. The second screw 411 is screwed into the threaded hole 221. After the blank is processed, the nut 212 is rotated in the opposite direction, and the pull rod 410 is pulled, which simultaneously drives the movable clamping plate 200 away from the fixed clamping plate 100, facilitating the removal and replacement of the processed blank.

[0039] Based on the above content and the accompanying drawings, those skilled in the art can understand and implement the present invention. In addition, any non-creative modifications made to the present invention by those skilled in the art without making any creative work still fall within the scope of protection of the present invention.
