Description

Technical Field

[0001] This application relates to the field of dental prosthesis processing technology, and more specifically, to an electric clamp and dental prosthesis processing equipment. Background Technology

[0002] In the prior art, the fixture used for processing denture blanks consists of two parts: a fixed part and a movable part. The fixed part is connected to the spindle of the machine tool, and the denture blank is positioned and clamped through the movable part and the fixed part.

[0003] The fixed and movable parts are usually connected by fastening screws. When changing materials, the bolts need to be unscrewed and then reinstalled, which makes loading and unloading of blanks inconvenient and results in low production efficiency.

[0004] To address the aforementioned issues, application number 201910144758.5 ​​discloses a fixture and dental prosthesis processing equipment, comprising a base, a pressure plate, and a shaft gear. The shaft gear is provided with teeth that mesh with the pressure plate and a threaded portion that is threadedly connected to the base. By rotating the pressure plate, the teeth mesh with the internal gear ring of the pressure plate, while simultaneously driving the threaded portion to continue to screw into the threaded hole of the base, thereby achieving the fixation of the blank.

[0005] Although the clamp does not require removing the shaft gear from the base, most of these manually rotated clamps do not bring about any performance changes.

[0006] While the fixture appears easy to disassemble, its practical value is actually quite low. It still requires manual rotation of the pressure plate and a large operating space. Furthermore, the powder from the processed blanks can easily clog the threaded holes of the base. It suffers from numerous drawbacks, such as cumbersome disassembly and assembly processes and low work efficiency. Therefore, the practicality of this fixture in the field of denture processing technology is limited.

[0007] Therefore, existing technologies need to be improved. Summary of the Invention

[0008] The purpose of this application is to provide an electric clamp and a denture processing device, which aims to solve the technical problem of how to quickly detach and install denture blanks from the clamp in the prior art.

[0009] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0010] In a first aspect, this application provides an electric clamp for clamping a denture blank, comprising:

[0011] Fixed clamping plate;

[0012] A movable clamping plate, which is movably disposed along a first direction;

[0013] A driving mechanism is provided, which is connected to the movable clamping plate and is used to drive the movable clamping plate to move along the first direction so that the movable clamping plate and the fixed clamping plate cooperate to form a clamping space.

[0014] In one embodiment, the drive mechanism includes one of the following structures:

[0015] Electromagnetic drive components, stepper motors, servo motors, and drive cylinders.

[0016] In one embodiment, the electric clamp further includes an elastic member that is elastically connected to the movable clamping plate. When the drive mechanism drives the movable clamping plate to move toward the fixed clamping plate, the elastic member deforms to generate a rebound force. When the drive mechanism is de-energized, the movable clamping plate is released by the rebound force of the elastic member.

[0017] In one embodiment, the electric clamp further includes a buffer pad located between the fixed clamp and the movable clamp.

[0018] In one embodiment, the electric clamp further includes a micro switch, which is disposed on the fixed clamping plate and electrically connected to the drive mechanism.

[0019] In one embodiment, the electric clamp further includes an indicator light, which is disposed on the fixed clamping plate and electrically connected to the drive mechanism.

[0020] In one embodiment, the fixed clamp includes:

[0021] Fixed body;

[0022] Several guide shafts are provided, which are detachably connected to the fixed body and are used to slide with the movable clamping plate.

[0023] In one implementation,

[0024] The driving mechanism includes an electromagnetic driving component, and the fixed body is provided with a first receiving cavity, in which the electromagnetic driving component is disposed.

[0028] The micro switch and the indicator light are disposed on the fixed body, and both the micro switch and the indicator light are electrically connected to the electromagnetic drive assembly. The micro switch is used to abut against the movable clamping plate.

[0029] The guide shaft includes a guide body, a guide sleeve, a threaded portion disposed at one end of the guide body, and a nut portion disposed at the end of the guide body away from the threaded portion. The guide body passes through the movable clamp, the guide sleeve, the compression spring, and the buffer pad in sequence. One end of the guide body is threadedly connected to the fixed body through the threaded portion, and the other end abuts against the movable clamp through the nut portion.

[0030] The fixed body drives the movable chuck to move along the guide shaft toward the fixed body via the electromagnetic drive assembly, so that the movable chuck and the fixed body cooperate to clamp the denture blank, and the compression spring generates a restoring force.

[0031] When the movable clamp moves to abut against the micro switch, the micro switch triggers a locking signal to restrict the movement of the movable clamp by the electromagnetic drive assembly;

[0032] When the electromagnetic drive assembly is de-energized, the movable clamp is springed open by the rebound force of the compression spring.

[0033] In one embodiment, the fixing body has a first clamping portion and a first notch portion, and the fixing body clamps the denture blank through the first clamping portion;

[0034] The fixing body is configured as a semi-circular structure, the first clamping part is an arc-shaped step formed by the inner ring wall of the fixing body, and the side of the arc-shaped step away from the denture blank is provided with a first guide slope.

[0035] The movable clamp includes a movable body, which has a second clamping part and a second notch part. The movable clamp holds the denture blank through the second clamping part.

[0036] The second clamping part is configured as a semi-circular structure, and a second guide slope is provided on the side of the second clamping part away from the denture blank.

[0037] Secondly, this application also provides a dental prosthesis processing device, wherein the dental prosthesis processing device includes the electric clamp as described above, thereby the dental prosthesis processing device can have all the features and effects of the electric clamp described above, which will not be repeated here.

[0038] The beneficial effects of the electric clamp and dental prosthesis processing equipment provided in this application are at least as follows:

The movable clamp is movably disposed along a first direction. The drive mechanism is driven by the movable clamp and is used to drive the movable clamp to move along the first direction, so that the movable clamp and the fixed clamp cooperate to form a clamping space. This application uses a drive mechanism to drive the movable clamp to move, thereby achieving automatic and rapid clamping of denture blanks by the movable and fixed clamps. It is simple to operate, convenient to disassemble, and changes the traditional method of disassembling and assembling denture blanks, saving operating space and improving work efficiency.

[0050] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0052] Example 1:

[0053] Please see Figure 1 This embodiment provides an electric clamp for clamping a denture blank 800, which includes: a fixed clamp 100, a movable clamp 200, and a drive mechanism 300. The movable clamp 200 is movably arranged along a first direction, and the drive mechanism 300 is drivenly connected to the movable clamp 200 to drive the movable clamp 200 to move along the first direction so that the movable clamp 200 and the fixed clamp 100 cooperate to form a clamping space.

[0054] In this embodiment, the movable clamp 200 is movably disposed along a first direction, which can be understood as the direction away from or close to the fixed clamp 100. Driven by the drive mechanism 300, the movable clamp 200 can move toward or away from the fixed clamp 100. For example, the drive mechanism 300 can drive the movable clamp 200 to move closer to the fixed clamp 100, so that the movable clamp 200 and the fixed clamp 100 cooperate to form a clamping space to clamp the denture blank 800. When it is necessary to remove the denture blank 800, the drive mechanism 300 can be de-energized so that the drive mechanism 300 no longer provides clamping force to the movable clamp 200, and the denture blank 800 can be removed. Alternatively, the movable clamp 200 can be driven to move away from the fixed clamp 100, so that the movable clamp 200 and the fixed clamp 100 open, and the denture blank 800 can be taken out. It can be seen that in this embodiment, there is no need to tighten screws or rotate the pressure plate. The drive mechanism 300 can automatically control the movable clamp 200 to clamp or open, which is convenient to operate and easy to disassemble, saves operating space, and improves work efficiency.

[0055] Therefore, in this embodiment, the movable clamping plate 200 is moved by the driving mechanism 300 to realize the automatic and rapid clamping of the denture blank 800 by the movable clamping plate 200 and the fixed clamping plate 100. The operation is simple and the disassembly is convenient. It changes the traditional disassembly and assembly method of the denture blank 800, saves operating space and improves work efficiency.

[0056] Optionally, the drive mechanism 300 may include one of the following structures:

[0057] Electromagnetic drive assembly 300a, stepper motor, servo motor and drive cylinder.

[0058] For example, the drive mechanism 300 may include an electromagnetic drive component 300a, which is drivenly connected to the movable clamp 200 and used to drive the movable clamp 200 to move along a first direction so that the movable clamp 200 and the fixed clamp 100 cooperate to form a clamping space. For example, when the electromagnetic drive component 300a is energized, it generates magnetism and can provide magnetic force to the movable clamp 200. The magnetic force can attract the movable clamp 200, so that the movable clamp 200 and the fixed clamp 100 cooperate to clamp the denture blank 800. When it is necessary to remove the denture blank 800, the electromagnetic drive component 300a is de-energized, the magnetic force disappears, and the electromagnetic drive component 300a no longer provides clamping force to the movable clamp 200, so the denture blank 800 can be easily removed. The electromagnetic drive component 300a can be set in the fixed chuck 100, and the movable chuck 200 can include a magnetic structure, such as iron, nickel or other magnetic materials. In this way, the movable chuck 200 does not need to be equipped with other power devices, which can simplify the structure and save space.

[0059] For example, the drive mechanism 300 may include a stepper motor, which can drive the movable clamp 200 to move closer to or further away from the fixed clamp 100. When the movable clamp 200 moves closer to the fixed clamp 100, the movable clamp 200 clamps the fixed clamp 100 and can be used to hold the denture blank 800. When the movable clamp 200 moves away from the fixed clamp 100, the movable clamp 200 is released from the fixed clamp 100, and at this time, the denture blank 800 can be removed from the fixture.

[0060] For example, the drive mechanism 300 may include a servo motor, which can drive the movable clamp 200 to move closer to or further away from the fixed clamp 100. When the servo motor drives the movable clamp 200 to move closer to the fixed clamp 100, the movable clamp 200 clamps the fixed clamp 100 and can be used to hold the denture blank 800. When the servo motor drives the movable clamp 200 to move away from the fixed clamp 100, the movable clamp 200 is released from the fixed clamp 100, and at this time, the denture blank 800 can be removed from the fixture.

[0061] For example, the drive mechanism 300 may include a drive cylinder, which can drive the movable clamp 200 to move closer to or away from the fixed clamp 100. When the drive cylinder drives the movable clamp 200 to move closer to the fixed clamp 100, the movable clamp 200 clamps the fixed clamp 100 and can be used to hold the denture blank 800. When the drive cylinder drives the movable clamp 200 to move away from the fixed clamp 100, the movable clamp 200 is released from the fixed clamp 100. At this time, the denture blank 800 can be removed from the fixture.

[0062] Example 2:

[0063] Please see Figure 2 The electric clamp also includes an elastic member 400, which is elastically connected to the movable clamp 200. When the drive mechanism 300 drives the movable clamp 200 to move toward the fixed clamp 100, the elastic member 400 deforms and generates a rebound force. When the drive mechanism 300 is de-energized, the movable clamp 200 is popped open by the rebound force of the elastic member 400.

[0064] In this embodiment, the electric clamp may include a fixed clamp 100, a movable clamp 200, a drive mechanism 300, and an elastic member 400. The elastic member 400 is elastically connected to the movable clamp 200. When the drive mechanism 300 drives the movable clamp 200 to move toward the fixed clamp 100, that is, when the drive mechanism 300 drives the movable clamp 200 to close, it is used to clamp the denture blank 800. At the same time, the elastic member 400 can deform to generate a rebound force. When it is necessary to release the denture blank 800, the drive mechanism 300 disconnects. The elastic component 400 can spring open the movable clamp 200 by relying on its rebound force, so that the movable clamp 200 releases the denture blank 800. On the one hand, when the movable clamp 200 moves towards the fixed clamp 100 and abuts against the fixed clamp 100, the elastic component 400 can offset part of the impact of the movable clamp 200, which has a buffering effect. On the other hand, relying on the elastic component 400 to spring open the movable clamp 200 does not require power drive, has a simple structure, fast response, saves costs, is easy to operate and disassemble, and can improve work efficiency.

[0065] Example 3:

[0066] Please see Figure 2 and Figure 3 The electric clamp also includes a buffer pad 500, which is located between the fixed clamp 100 and the movable clamp 200.

[0067] In this embodiment, the electric clamp may include a fixed clamp 100, a movable clamp 200, a drive mechanism 300, and a buffer pad 500. The buffer pad 500 is located between the fixed clamp 100 and the movable clamp 200. The buffer pad 500 has a buffering function, which can buffer the impact of the movable clamp 200 and reduce noise. For example, when a denture blank 800 is placed on the fixed clamp 100, and then the drive mechanism 300 drives the movable clamp 200 to move toward the fixed clamp 100, when the movable clamp 200 and the fixed clamp 100 are closed, the buffer pad 500 has a certain elasticity and buffering, which can reduce the impact force of the movable clamp 200 on the denture blank 800 and prevent damage to the movable clamp 200 and the fixed clamp 100, thus providing a protective function.

[0068] Example 4:

[0069] Please see Figure 4 and Figure 5 The electric clamp also includes a micro switch 600, which can be mounted on the fixed clamping plate 100 and is electrically connected to the drive mechanism 300.

[0070] In this embodiment, the electric clamp may include a fixed clamping plate 100, a movable clamping plate 200, a drive mechanism 300, and a micro switch 600. The micro switch 600 may be disposed on the fixed clamping plate 100 and is electrically connected to the drive mechanism 300. When the drive mechanism 300 drives the movable clamping plate 200 to move toward the fixed clamping plate 100, so that the movable clamping plate 200 and the fixed clamping plate 100 are closed, the micro switch 600 may come into contact with the movable clamping plate 200, thereby triggering the micro switch 600. The micro switch 600 may provide a locking signal to the host computer or controller 900 to control the drive mechanism 300 to provide a stable clamping force.

[0071] Example 5:

[0072] Please see Figure 4 and Figure 5 The electric clamp also includes an indicator light 700, which is mounted on the fixed clamping plate 100 and is electrically connected to the drive mechanism 300.

[0073] In this embodiment, the electric clamp may include a fixed clamping plate 100, a movable clamping plate 200, a drive mechanism 300, a micro switch 600, and an indicator light 700. The indicator light 700 may be disposed on the fixed clamping plate 100 and can provide a signal indicating a locking or unlocking. For example, the electric clamp may include a fixed clamping plate 100, a movable clamping plate 200, a drive mechanism 300, a micro switch 600, an indicator light 700, and a controller 900. When the drive mechanism 300 drives the movable clamping plate 200 to move towards the fixed clamping plate 100, so that the movable clamping plate 200 and the fixed clamping plate 100 close to clamp the denture blank 800, the micro switch 600 can come into contact with the movable clamping plate 200, thereby triggering the micro switch 600. The micro switch 600 can provide a locking signal to the host computer or the controller 900. At the same time, the indicator light 700 can light up to indicate to the operator that the movable clamping plate 200 is in the locked state. For example, the indicator light 700 can show a red light to indicate to the operator that the movable clamping plate 200 is in the locked state. When the movable clamping plate 200 is released, the indicator light 700 can show a green light to indicate to the operator that the movable clamping plate 200 is in the released state. The host computer and the controller 900 can be understood as prior art and will not be described in detail.

[0074] Example 6:

[0075] Please see Figure 5 The fixed clamp 100 includes a fixed body 110 and a plurality of guide shafts 120. The guide shafts 120 are detachably connected to the fixed body 110 and are used to slide with the movable clamp 200.

[0076] In this embodiment, the fixed clamping plate 100 includes a fixed body 110 and several guide shafts 120. The guide shafts 120 are slidably connected to the movable clamping plate 200. When the driving mechanism 300 drives the movable clamping plate 200 to move towards the fixed clamping plate 100, the movable clamping plate 200 can move directionally along the guide shafts 120, which facilitates the movement of the movable clamping plate 200, prevents the movable clamping plate 200 from shifting, and ensures the mutual clamping of the movable clamping plate 200 and the fixed clamping plate 100. The guide shafts 120 can be detachably connected to the fixed clamping plate 100 to facilitate the installation and maintenance of the guide shafts 120. For example, the number of guide shafts 120 can be three, and the three guide shafts 120 are distributed in a triangular relationship. It should be understood that the number of guide shafts 120 is not limited to the above-mentioned three, and the number of guide shafts 120 can also be other cases, which are not limited here.

[0077] Example 7:

[0078] Please see Figure 2 and Figure 6 The electric clamp may include a fixed clamping plate 100, a movable clamping plate 200, a drive mechanism 300, an elastic component 400, a buffer pad 500, a micro switch 600, and an indicator light 700. The drive mechanism 300 may include an electromagnetic drive assembly 300a. A first receiving cavity 111 is provided on the fixed body 110, and the electromagnetic drive assembly 300a is provided in the first receiving cavity 111.

[0079] The elastic component 400 includes a compression spring 410;

[0080] The buffer pad 500 is disposed on the fixed body 110 and covers the electromagnetic drive assembly 300a;

[0081] The micro switch 600 and the indicator light 700 are mounted on the fixed body 110, and both the micro switch 600 and the indicator light 700 are electrically connected to the electromagnetic drive assembly 300a. The micro switch 600 is used to abut against the movable clamp 200.

[0082] The guide shaft 120 includes a guide body 121, a guide sleeve 122, a threaded portion 123 disposed at one end of the guide body 121, and a nut portion 124 disposed at the end of the guide body 121 away from the threaded portion 123. The guide body 121 passes through the movable clamp 200, the guide sleeve 122, the compression spring 410, and the buffer pad 500 in sequence. One end of the guide body 121 is threadedly connected to the fixed body 110 through the threaded portion 123, and the other end abuts against the movable clamp 200 through the nut portion 124.

[0083] The fixed body 110 drives the movable chuck 200 to move along the guide shaft 120 toward the fixed body 110 via the electromagnetic drive assembly 300a, so that the movable chuck 200 and the fixed body 110 cooperate to clamp the denture blank 800, and the compression spring 410 generates a rebound force.

[0084] When the movable clamp 200 moves to abut against the micro switch 600, the micro switch 600 triggers a locking signal to restrict the movement of the movable clamp 200 by the electromagnetic drive assembly 300a.

[0085] When the electromagnetic drive assembly 300a is de-energized, the movable clamp 200 is released by the rebound force of the compression spring 410.

[0086] In this embodiment, the drive mechanism 300 can be an electromagnetic drive assembly 300a. For example, the electromagnetic drive assembly 300a can consist of two electromagnets 310, which are respectively disposed in the first receiving cavity 111 on the fixed body 110. The buffer pad 500 can be placed on the electromagnetic drive assembly 300a. The buffer pad 500 can have a buffering function and can also act as a cover plate to seal and protect the electromagnets 310. The micro switch 600 can be disposed on the fixed body 110 and exposed on the buffer pad 500. The movable clamp 200 and the fixed clamp 100 can be slidably connected via a guide shaft 120. For example, the guide shaft 120 can be detachably connected to the fixed body 110 via a threaded portion 123. The other end of the guide shaft 120 can abut against the top surface of the movable clamp 200 via a nut portion 124. The movable clamp 200 can slide along the guide body 121, and the guide body 121 passes through the guide sleeve 122 and the compression spring 410. A second receiving cavity 214 can be provided on the side of the movable clamp 200 near the fixed clamp 100. Figure 7 As shown in the diagram, the second receiving cavity 214 is used to install the guide sleeve 122, which is used to abut against one end of the compression spring 410. The other end of the compression spring 410 can abut against the fixed clamping plate 100, or the other end of the compression spring 410 can abut against the buffer pad 500 on the fixed clamping plate 100.

[0087] For example, when the two electromagnets 310 are energized, they generate magnetism. The movable clamp 200 can be made of magnetic material. In this case, the electromagnets 310 generate a magnetic force on the movable clamp 200, attracting it to move towards the fixed clamp 100. That is, the movable clamp 200 can move directionally along the guide shaft 120 under the drive of the magnetic force, thus clamping the denture blank 800. The compression spring 410 generates a rebound force due to compression. When the movable clamp 200 comes into contact with the micro switch 600, the micro switch 600 is triggered. The micro switch 600 can provide a locking signal to the controller 900. Based on the locking signal, the controller 900 can stably control the electromagnetic force of the electromagnets 310 to stabilize... The fixed clamp holds the denture blank 800, while the controller 900 can control the indicator light 700 to illuminate red to indicate to the operator that the movable clamp 200 is in the locked state. The buffer pad 500 is located between the fixed clamp 100 and the movable clamp 200, and the buffer pad 500 has a buffering function and can reduce noise. When the processing is completed or when it is necessary to release the denture blank 800, the controller 900 can control the electromagnet 310 to de-energize, and the movable clamp 200 will spring open by the compression spring 410, so that the movable clamp 200 and the fixed clamp 100 are in the loose state. When the electromagnet 310 is de-energized, the controller 900 can control the indicator light 700 to illuminate green to indicate to the operator that the movable clamp 200 is in the loose state. The operation is convenient and facilitates the quick assembly and disassembly of the denture blank 800, which can improve work efficiency.

[0088] Specifically, please refer to Figure 2 The fixing body 110 may have a first clamping part 112 and a first notch part 113, and the fixing body 110 clamps the denture blank 800 through the first clamping part 112.

[0089] In this embodiment, the fixing body 110 can clamp the denture blank 800 through the first clamping part 112. The first notch part 113 can reduce the clamping contact area between the first clamping part 112 and the denture blank 800, thereby improving the utilization rate of raw materials (denture blank 800). At the same time, the first notch part 113 facilitates processing and provides clearance space for machining. For example, the first notch part 113 occupies one-third to one-half of the area of ​​the fixing body 110, that is, one-half to two-thirds of the denture blank 800 is used for clamping and fixing, which can ensure that the clamping is firm and reliable. On this basis, since the first notch part 113 can provide clearance space, it can facilitate processing, improve work efficiency, and at the same time, it can greatly improve the utilization rate of the denture blank 800, save raw materials, and save costs.

[0090] Please see Figure 6The fixing body 110 is configured as a semi-circular structure. The first clamping part 112 is an arc-shaped step 114 formed by the inner ring wall of the fixing body 110. The arc-shaped step 114 is provided with a first guide slope 115 on the side away from the denture blank 800.

[0091] In this embodiment, the fixing body 110 is configured as a semi-circular structure, and the first clamping part 112 is an arc-shaped step 114 formed by the inner ring wall of the fixing body 110. The arc-shaped step 114 can be adapted to the denture blank 800 and can firmly clamp the denture blank 800, preventing the denture blank 800 from loosening or shaking during processing. Furthermore, a first guide slope 115 is provided on the side of the arc-shaped step 114 away from the denture blank 800. The first guide slope 115 can provide clearance space for the processing tool, which can facilitate processing and improve work efficiency.

[0092] Please see Figure 6 The movable clamp 200 includes a movable body 210, which has a second clamping part 211 and a second notch 212. The movable clamp 200 clamps the denture blank 800 through the second clamping part 211.

[0093] In this embodiment, the movable body 210 has a second clamping portion 211 and a second notch portion 212. The movable chuck 200 clamps the denture blank 800 through the second clamping portion 211. The second notch portion 212 can reduce the clamping contact area between the second clamping portion 211 and the denture blank 800, thereby improving the utilization rate of raw materials (denture blank 800). At the same time, the second notch portion 212 facilitates processing and provides clearance space for machining. For example, the second notch portion 212 occupies one-third to one-half of the area of ​​the movable body 210, that is, one-half to two-thirds of the denture blank 800 is used for clamping and fixing, which can ensure that the clamping is firm and reliable. On this basis, since the second notch portion 212 can provide clearance space, it can facilitate processing, improve work efficiency, and at the same time, it can greatly improve the utilization rate of the denture blank 800, save raw materials, and save costs.

[0094] Please see Figure 6 The second clamping part 211 is configured as a semi-circular structure, and a second guide slope 213 is provided on the side of the second clamping part 211 away from the denture blank 800.

[0095] In this embodiment, as described above, the second clamping part 211 is configured as a semi-annular structure, and a second guide slope 213 is provided on the side of the second clamping part 211 away from the denture blank 800. For example, the denture blank 800 can be configured as a cylindrical structure, wherein a protruding ring 810 can be provided on the outer wall of the cylindrical structure. The fixed chuck 100 can abut against the bottom of the protruding ring 810 through the first clamping part 112, while the movable chuck 200 can abut against the top of the protruding ring 810 through the second clamping part 211. That is, driving the movable chuck 200 to move downward and press against the top of the protruding ring 810 can achieve the clamping of the denture blank 800. The second guide slope 213 can provide clearance space for machining, which can facilitate machining and improve work efficiency.

[0096] Secondly, this application also provides a dental prosthesis processing device, wherein the dental prosthesis processing device includes the electric clamp as described in the above embodiment, thereby the dental prosthesis processing device can have all the features and effects of the electric clamp described above, which will not be repeated here.

[0097] For example, taking the electromagnetic drive component 300a as an example, a denture processing device may include a base, an electric clamp as described in the above embodiment, and a cutting tool mechanism. The base may be equipped with the electric clamp and the cutting tool mechanism. The electric clamp can be used to clamp the denture blank 800, for example, it can be used to clamp a zirconia ceramic block. The electric clamp includes a fixed clamp 100, a movable clamp 200, and an electromagnetic drive component 300a. The electromagnetic drive component 300a can be disposed on the fixed clamp 100. The movable clamp 200 may include a magnetic structure and may be made of a magnetic material, such as iron sheet. The denture blank 800 is pre-positioned within the arc-shaped step 114 of the fixed clamp 100 to achieve pre-positioning of the denture blank 800. Then, the electromagnetic drive component 300a is energized, and the electromagnetic drive component 300a can... The movable chuck 200 is attracted to move along the guide shaft 120 toward the fixed chuck 100, so that the movable chuck 200 and the fixed chuck 100 cooperate to form a clamping space, thereby clamping the denture blank 800. When the movable chuck 200 abuts against the micro switch 600 on the fixed chuck 100, the buffer pad 500 has a buffering effect and can press the denture blank 800. The micro switch 600 can trigger a locking signal, and the indicator light 700 can light up to indicate clamping. At this time, the tool mechanism can be started to process the denture blank 800, so that the denture blank 800 is formed into the designed product shape. After processing is completed, the electromagnetic drive component 300a is de-energized, and the movable chuck 200 can be released by the compression spring 410 to release the remaining denture blank 800, so that the denture blank 800 can be disassembled. The operation is convenient and the work efficiency is high.

[0098] In summary, this application discloses an electric clamp and a denture processing device. The electric clamp includes a fixed clamp, a movable clamp, and a drive mechanism. The movable clamp is movably disposed along a first direction, and the drive mechanism is driven by and connected to the movable clamp to move it along the first direction, so that the movable clamp and the fixed clamp cooperate to form a clamping space. This application uses a drive mechanism to move the movable clamp, enabling the movable and fixed clamps to automatically and quickly clamp denture blanks. The operation is simple, disassembly is convenient, and it changes the traditional method of disassembling and assembling denture blanks, saving operating space and improving work efficiency.
