Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In view of the shortcomings of the prior art, this embodiment provides a quick-change fixture for denture processing, which can be specifically described as follows:

[0039] As attached Figure 1 and attached Figure 2 As shown, a quick-change fixture for denture processing includes a fixed table 1, a rotating component 2, a plurality of zero-point locators 6 and a fixing part 3. The interior of the denture processing equipment includes a fixed table 1 and various components for processing. The fixed table 1 and the various components for processing belong to the prior art and are similar to the internal structure of a machine tool. A rotating component 2 is arranged on the fixed table 1, and a plurality of zero-point locators 6 are arranged on the rotating component 2. The zero-point locator 6 is the prior art. The zero-point locator 6 is connected to an external air pump. A detachable fixing part 3 is arranged on the top of the zero-point locator 6. A plurality of cargo pieces 5 are arranged on the side of the fixing part 3 away from the zero-point locator 6. The cargo pieces 5 are used for processing. A plurality of rivets 4 are arranged on the side of the fixing part 3 close to the zero-point locator 6. The rivets 4 correspond to the zero-point locators 6 one by one and cooperate with each other to fix the zero-point locator 6 to the fixing part 3, so as to facilitate the processing of the cargo pieces 5.

[0040] Specifically, in the initial state, the rivet 4 is installed together with the fixing part 3. When processing is required, multiple cargo parts 5 can be installed on the fixing part 3 one by one, and then the ball in the zero point locator 6 is unlocked by starting the air pump, and then the rivet 4 at the bottom of the fixing part 3 is matched with the zero point locator 6. Since the ball in the zero point locator 6 has been unlocked, the rivet 4 can be directly clamped in the zero point locator 6, and then the air pump is turned off. The ball in the zero point locator 6 will be clamped on the arc surface of the rivet 4 under the action of the internal tension spring, and both sides of the ball are locked and cannot move, so that the rivet 4 is fixed in the zero point locator 6, thereby fixing the fixing part 3; when the processing is completed, the ball can be unlocked by starting the air pump again, and it can be moved in the cavity in the zero position locator. The rivet 4 can squeeze the ball to move and disengage from the zero point locator 6, so that the fixing part 3 can be taken out, which is convenient for replacing the next cargo part 5.

[0041] Furthermore, the zero point locator 6 has two types, with or without a sensor. The principle is that the large-diameter, high-rigidity ball inside the zero point locator 6 clamps the pull pin 4. When 6 bar air pressure is passed into the zero point positioning chuck, the balls spread to both sides, and the pull pin 4 can freely enter and exit the zero point positioning chuck; when the pressure is cut off, the spring pushes the piston upward to gather the balls to the center, so that the balls constrain the lock pull pin 4 on three sides, so that the positioning and clamping actions are completed synchronously. The repeated positioning accuracy of the two is less than 0.005mm, and a clamping force of 5-30KN is provided at the same time. With a sensor, the piston position can be judged by the pressure of the air pressure back pressure, and the zero point locator 6 is monitored to determine whether it is locked.

[0042] In one embodiment of the present application, as shown in the attached Figure 2 As shown, the rotating assembly 2 includes two fixed sleeves 21, two rotating shafts 22, a fixed block 23 and a motor. A fixed frame is provided at one end of the fixed platform 1, and a supporting frame is provided at the other end. The two fixed sleeves 21 are respectively arranged on the fixed frame and the supporting frame. The middle of the fixed sleeve 21 is a through hole, and a rotating shaft 22 is rotatably arranged in the through hole. A fixed block 23 is arranged between the two rotating shafts 22, and both ends of the fixed block 23 are respectively connected to the two rotating shafts 22. A motor is also provided on the fixed platform 1. The motor is arranged inside the fixed frame, and the output shaft of the motor is connected to the rotating shaft 22 arranged on the fixed frame. The fixed block 23 can be driven to rotate by the motor, so that the fixed component 3 and the cargo 5 are rotated.

[0043] In this embodiment, as shown in the attached Figure 4 and attached Figure 5As shown in the figure, first mounting grooves are provided on both sides of the two rotating shafts 22 facing each other. The first mounting grooves are formed by cutting along the central axis of the rotating shaft 22 towards one side. Both ends of the fixing block 23 are provided with mating grooves, which are matched with the first mounting grooves and fixed by bolts. A second mounting groove is opened at the middle position of the surface of the fixing block 23, so that the fixing block 23 is in an inverted "L" shape; a plurality of zero-point locators 6 are arranged in the second mounting groove. By setting the fixing block 23 in an inverted "L" shape, the distance between the fixing member 3 and the axis of the rotating shaft 22 can be reduced, thereby ensuring the machining rigidity and stability of the fixing member 3.

[0044] Further, a fixing groove is opened on the second mounting groove. The fixing groove is a circular groove, which is sleeved with the bottom of the zero-point locator 6 to facilitate the fixing of the zero-point locator 6.

[0045] In one embodiment of the present application, as shown in the attached Figure 3 and the attached Figure 6 figure, steps 31 are provided on both sides of the fixing member 3. By providing the steps 31, the weight of the fixing member 3 can be reduced while ensuring the contact area between the fixing member 3 and the zero-point locator 6; one end of the step 31 close to the middle of the fixing frame is higher than the end of the step 31 far from the middle of the fixing frame, so that the surface of the step 31 is inclined; when the workpiece 5 on the fixing member 3 is processed, processing waste will fall on the step 31. By setting the step 31 to be inclined, the waste can automatically fall off to avoid affecting the processing of the denture equipment.

[0046] In this embodiment, the surface of the fixing table 1 is inclined, and the bottom of the fixing table 1 is a collection cavity. The processing waste will fall on the inclined surface of the fixing table 1 and then fall into the collection cavity to prevent the waste from accumulating on the fixing table 1 and affecting the processing of the workpiece 5.

[0047] In one embodiment of the present application, as shown in the attached Figure 2 、the attached Figure 6 and the attached Figure 7 figure, a plurality of through holes 32 are provided on the fixing member 3.

A bolt is provided in the counterbore 33, and the bolt is connected to the threaded groove 51 of the workpiece 5; by matching the bolt with the threaded groove 51 of the workpiece 5 and pulling the workpiece 5, the workpiece 5 can be fixed on the fixing member 3 to facilitate the denture equipment to process the workpiece 5; and the large head end of the bolt can be arranged in the counterbore 33 to avoid protruding from the surface of the fixing member 3 and affecting the processing.

[0048] In this embodiment, as shown in the attached Figure 7As shown, a stepped groove 52 is provided at the bottom of the cargo piece 5, and the top of the stepped groove 52 abuts against the surface of the fixing member 3; specifically, the stepped groove 52 is an annular groove, and the diameter of the bottom of the cargo piece 5 is the same as the diameter of the through hole 32, so that the bottom of the cargo piece 5 can be inserted into the through hole 32, and the top wall of the stepped groove 52 abuts against the surface of the fixing member 3, and then the cargo piece 5 is pulled by the bolts at the bottom of the fixing member 3, so that the cargo piece 5 is fixed in the fixing member 3.

[0049] Furthermore, a first plane is provided on the side wall of the stepped groove 52 , and a second plane is provided on the inner wall of the through hole 32 . The first plane cooperates with the second plane to prevent the cargo piece 5 from rotating in the through hole 32 .

[0051] In one embodiment of the present application, as shown in the attached Figure 5 As shown, a channel 24 is provided inside the fixed block 23, one end of the channel 24 is connected to the zero point locator 6, and the other end is connected to an external air pump; specifically, an air inlet is provided at the bottom of the zero point locator 6, the bottom wall of the zero point locator 6 abuts against the fixed block 23 and is sealed, the zero point locator 6 is connected to the channel 24, and the other end of the channel 24 is connected to an air pipe, which is connected to an external air pump; when the air pump is started, ventilation can be carried out into the zero point locator 6.

[0052] Furthermore, there may be multiple channels 24 , and the multiple channels 24 are respectively connected to multiple zero point positioners 6 ; there may also be one channel 24 , and the channel 24 is connected to multiple zero point positioners 6 .

[0053] In this embodiment, as shown in the attached Figure 8 As shown, a first positioning hole 61 is provided on the zero point locator 6, and a positioning pin 34 is provided at the bottom of the fixing member 3; when the zero point locator 6 cooperates with the rivet 4 at the bottom of the fixing member 3, the positioning pin 34 can cooperate with the first positioning hole 61, so that the zero point locator 6 and the rivet 4 are positioned, and shaking or displacement between the rivet 4 and the zero point locator 6 can be prevented.
