[0003] According to a clamping structure for denture processing with authorization announcement number CN215036745U, this patent is a known prior art, and although this patent has the advantage of being able to fix dentures of different sizes, thereby improving practicality, the technical solution of this patent still has the following defects during actual use: when the first spring is used to drive the clamping rod to extrude and fix the denture base, when the denture base is being processed, the first spring is easily driven by the force to drive the clamping rod to move in the opposite direction, causing looseness between the clamping rod and the denture base, which easily causes the denture base to shake, resulting in poor stability during denture base processing. For this reason, we propose a denture cutting machine clamping device. Utility Model Content

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following examples are intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention. The conditions in the examples may be further adjusted according to specific conditions. Simple improvements to the method of the present invention based on the concept of the present invention fall within the scope of protection claimed by the present invention.

[0021] Example 1

[0022] See also Figure 1 and Figure 2 The utility model provides a denture cutting machine clamping device, including a chuck 1 and a slider 8. A denture base placement groove 2 is provided in the middle of the front of the chuck 1, a groove 3 is provided on the front of the chuck 1, a movable spring 4 and an electromagnet 5 are provided inside the groove 3, a fixed claw 6 is provided at one end of the movable spring 4, one end of the movable spring 4 is fixedly connected to the middle of the other side of the fixed claw 6, and the other end of the movable spring 4 is fixedly connected to the inner wall of the chuck 1, a fixed pad 7 is fixedly connected to one side of the fixed claw 6, the fixed claw 6 is located above the electromagnet 5, and the material of the fixed pad 7 is rubber material;

[0023] In this embodiment, the denture base to be processed is first placed into the denture base placement slot 2, and then the circuit of the electromagnet 5 is disconnected, so that the electromagnet 5 loses its magnetic force due to power failure. At this time, the electromagnet 5 and the slider 8 will become loose, and the movable spring 4 that was originally in a compressed state will undergo elastic deformation and apply force to the fixing claw 6, so that the fixing claw 6 drives the fixing pad 7 to move horizontally, causing the fixing pad 7 to be in close contact with the outside of the denture base, thereby facilitating the extrusion and fixation of the denture base.

[0024] One side of the electromagnet 5 is magnetically connected to a slider 8, which is made of iron. The slider 8 and the electromagnet 5 are in contact with each other. One side of the slider 8 is fixedly connected to the other side of the fixed claw 6. The back of the slider 8 is fixedly connected to a positioning block 9. A positioning groove 10 is provided inside the groove 3. The positioning block 9 is movably sleeved inside the positioning groove 10. The positioning block 9 and the positioning groove 10 are adapted to each other. A mounting hole 11 is provided on the front of the chuck 1. The mounting hole 11 is used to fix the chuck 1 on the denture cutting machine.

[0025] In this embodiment, when the fixing pad 7 is pressed and contacted with the outside of the denture base, the circuit of the electromagnet 5 is turned on, so that the electromagnet 5 generates a magnetic force due to the power supply. At this time, magnetic attraction occurs between the electromagnet 5 and the slider 8, which facilitates the firm fixation of the position of the fixing claw 6, avoiding the problem of shaking of the denture base due to force during processing, and also ensures that the movable spring 4 will not be elastically deformed due to force during processing, thereby improving the stability of the denture base during processing;

[0026] When the fixed claw 6 moves under the elastic force of the movable spring 4, the fixed claw 6 will drive the slider 8 to move, and the slider 8 will drive the positioning block 9 to slide inside the positioning groove 10, thereby facilitating the positioning of the movement direction of the fixed claw 6. At the same time, when the chuck 1 needs to be installed on the denture cutting machine, the chuck 1 can be placed in the tool working area of ​​the cutting machine, and the mounting screw can be inserted into the mounting hole 11, and the mounting screw can be rotated to make it threadedly connected to the denture cutting machine, thereby facilitating the flat installation of the clamping device.

[0027] Example 2

[0028] See also Figure 3 The present embodiment of a denture cutting machine jaw device adds a mounting assembly 12 on the basis of the first embodiment. The mounting assembly 12 is arranged on the back of the chuck 1. The mounting assembly 12 includes a mounting sleeve 121. The mounting sleeve 121 is located in the middle of the back of the chuck 1. The internal thread of the mounting sleeve 121 is connected to a fixing bolt 122. The side of the mounting sleeve 121 is fixedly connected to a mounting plate 123. The mounting plate 123 and the chuck 1 are fixedly connected by bolts.

[0029] In this embodiment, when the installation object on the denture cutting machine is a cylindrical part, the installation sleeve 121 is first placed in the middle of the back of the chuck 1, and the installation plate 123 is fixed to the back of the chuck 1 with bolts. Then, the chuck 1 is picked up, and the installation sleeve 121 is put on the outside of the cylindrical installation object, and the fixing bolt 122 is rotated to extend it to the inside of the cylindrical installation object, thereby facilitating the installation of the clamping device.

[0030] In the above scheme, it should be noted that: since the shape of the denture base placement groove 2 in this application is circular, and the shape of the fixing pad 7 is arc-shaped, the clamping device of this application is suitable for adjusting and fixing the cylindrical denture base.

[0031] The working principle and use process of the present invention are as follows: first, the denture base to be processed is placed inside the denture base placement groove 2, and then the circuit of the electromagnet 5 is disconnected, so that the electromagnet 5 loses its magnetic force due to power failure. At this time, the electromagnet 5 and the slider 8 will become loose, and the movable spring 4 in the originally compressed state will elastically deform and apply force to the fixing claw 6, so that the fixing claw 6 drives the fixing pad 7 to move horizontally, so that the fixing pad 7 and the outer part of the denture base are in close contact, which is convenient for squeezing and fixing the denture base;

[0032] Then, the circuit of the electromagnet 5 is turned on, so that the electromagnet 5 generates magnetic force due to the power supply. At this time, magnetic attraction occurs between the electromagnet 5 and the slider 8, which facilitates the firm fixation of the position of the fixing claw 6, avoiding the problem of shaking of the denture base due to force during processing. At the same time, it also ensures that the movable spring 4 will not be elastically deformed due to force during processing, thereby improving the stability of the denture base during processing;

[0033] Finally, when the fixed claw 6 moves under the elastic force of the movable spring 4, the fixed claw 6 will drive the slider 8 to move, and the slider 8 will drive the positioning block 9 to slide inside the positioning groove 10, thereby facilitating the positioning of the movement direction of the fixed claw 6.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
