Description

Technical Field

[0001] This utility model relates to the field of dental crown processing technology, and in particular to an auxiliary fixture for polishing titanium alloy dental crowns. Background Technology

[0002] During the polishing process of titanium alloy dental crowns, in order to avoid uneven force caused by direct hand handling and to ensure processing accuracy and safety, nickel-titanium clamping rings are used to assist in clamping the dental crowns.

[0003] Currently, existing nickel-titanium clamping rings mainly consist of three parts: the clamping body, the chuck, and the handle. The chuck needs to provide stable support through tight clamping. During high-speed polishing, the crown and the inside of the chuck will experience continuous relative micro-slippage, which can easily lead to wear on the contact surface of the chuck. Since the chuck is usually glued to the clamping body, when the chuck wears out, in order to ensure stable clamping of the crown in the future, the operator has to scrap the entire nickel-titanium clamping ring. To address this problem, we propose a titanium alloy crown processing and polishing auxiliary fixture. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary fixture for the processing and polishing of titanium alloy dental crowns.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A titanium alloy dental crown processing and polishing auxiliary fixture includes a clamping body, a handle fixedly connected to the bottom end of the clamping body, a support plate provided at the top end of the clamping body, and an insertion plate fixedly connected to the top end of the support plate. A chuck is provided above the support plate, and an insertion slot adapted to the insertion plate is opened inside the chuck. A rectangular groove is opened inside the support plate, and a connecting spring is horizontally connected to the inner wall of the rectangular groove. The end of the connecting spring is fixedly connected to the connecting plate, and a positioning rod is provided on the inner side of the connecting plate. The positioning rod extends through the inner wall of the chuck into the insertion plate.

[0007] Preferably, a rubber plate is fixedly connected to the inner side of the connecting plate, and the other end of the rubber plate is fixedly connected to the end of the positioning rod.

[0008] Preferably, an insertion rod is fixedly connected to the inner side of the rubber plate, and an insertion groove adapted to the insertion rod is opened inside the support plate.

[0009] Preferably, the connecting plate has a slot on its side, and a pull rod is fixedly connected to the inner wall of the slot.

[0010] Preferably, the bottom end of the support plate is fixedly connected to an installation plate, and threaded rods are inserted into the interior of the installation plate. The ends of the threaded rods are fixedly connected to the clamping body, and threaded sleeves are respectively fitted on the outer sides of the threaded rods.

[0011] Preferably, there are two sets of connecting springs and insertion rods, and the two sets of connecting springs and insertion rods are symmetrically distributed about the central axis of the support plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This device is equipped with a support plate and an insertion plate. When the clamp is damaged after a period of use, the operator can pull the connecting plate laterally to move the positioning rod laterally, thereby achieving quick disassembly of the clamp. The intact clamping body and handle can then be reused, effectively reducing resource waste.

[0014] 2. The device is equipped with a rubber plate and a pull rod. During use, the rubber plate can effectively prevent the connecting plate from directly colliding with the clamp when it is reset, thus protecting the clamp and the connecting plate. With the pull rod, it is easy for the operator to quickly pull the connecting plate horizontally. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A titanium alloy dental crown processing and polishing auxiliary fixture includes a clamping body 1, a handle 2 fixedly connected to the bottom end of the clamping body 1, a support plate 3 provided at the top end of the clamping body 1, and an insertion plate 4 fixedly connected to the top end of the support plate 3. A chuck 5 is provided above the support plate 3, and an insertion groove adapted to the insertion plate 4 is opened inside the chuck 5. Through the mutual cooperation of the insertion plate 4 and the insertion groove, the chuck 5 can be pre-positioned above the support plate 3 to ensure that the subsequent positioning rod 9 is accurately inserted into the insertion plate 4 for connection. A rectangular groove 6 is opened inside the support plate 3, and a connecting spring 7 is horizontally connected to the inner wall of the rectangular groove 6. The end of the connecting spring 7 is fixedly connected to a connecting plate 8, and a positioning rod 9 is provided on the inner side of the connecting plate 8. The positioning rod 9 extends through the inner wall of the chuck 5 into the insertion plate 4.

[0022] Furthermore, refer to Figure 3 and Figure 4 It can be seen that a rubber plate 10 is fixedly connected to the inner side of the connecting plate 8, and the other end of the rubber plate 10 is fixedly connected to the end of the positioning rod 9. During use, the rubber plate 10, which is made of rubber material, can effectively prevent the connecting plate 8 from colliding directly with the outer wall of the clamp 5 when it is reset, thus achieving simultaneous protection for both.

[0023] Furthermore, refer to Figure 4 It can be seen that the rubber plate 10 is fixedly connected to the inner side of the insertion rod 11, and the support plate 3 has an insertion groove that matches the insertion rod 11. When the worker pulls the connecting plate 8 laterally, the rubber plate 10 can move under force at the same time. At this time, the insertion rod 11 connected to the inner side of the rubber plate 10 can slide along the inner wall of the insertion groove under force, so as to achieve lateral guidance of the connecting plate 8 and the positioning rod 9, thereby effectively preventing the positioning rod 9 from getting stuck during insertion and retraction.

[0024] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the side of the connecting plate 8 is provided with a slot, and the inner wall of the slot is fixedly connected with a pull rod 12. The pull rod 12 can provide a force point for the staff to pull the connecting plate 8, so as to effectively improve the convenience of the staff to pull the connecting plate 8.

[0025] Furthermore, refer to Figure 3It can be seen that the bottom end of the support plate 3 is fixedly connected to the mounting plate 13, and the mounting plate 13 is inserted with threaded rods 14. The ends of the threaded rods 14 are fixedly connected to the clamping body 1. Threaded sleeves 15 are respectively fitted on the outside of the threaded rods 14. When the connecting spring 7 loses its elasticity after a period of use, the operator can use an auxiliary tool to rotate the threaded sleeve 15, so that it can be removed from the outside of the threaded rod 14. Then the operator can pull the support plate 3 horizontally, so that the mounting plate 13 can be pulled out from the outside of the threaded rod 14 by force, so as to replace the support plate 3.

[0026] Furthermore, refer to Figure 4 It can be seen that there are two sets of connecting springs 7 and insertion rods 11, and the two sets of connecting springs 7 and insertion rods 11 are symmetrically distributed about the central axis of the support plate 3. The setting of two sets of connecting springs 7 can ensure the stability of the positioning rod 9 inserted into the insertion plate 4, and the setting of two sets of insertion rods 11 can further ensure the stable movement of the connecting plate 8.

[0027] Working principle: When using this utility model, the operator can squeeze the two sets of handles 2 to compress and deform the clamping body 1. The two sets of clamps 5 set at the front end of the clamping body 1 can clamp and fix the titanium alloy crown. Then, the operator can use a polishing device to polish the clamped crown. When the clamps 5 are damaged after a period of use, the operator can pull the pull rod 12 laterally, which will drive the connecting plate 8 to move laterally and pull out the positioning rod 9 connected to the inside of the connecting plate 8 from the inside of the insertion plate 4. At this time, the operator can pull up the clamps 5 to pull them out from the outside of the insertion plate 4. Then, the operator can insert a new set of clamps 5 into the outside of the insertion plate 4 and then stop pulling the connecting plate 8 so that the positioning rod 9 can be embedded back into the clamps 5 and the insertion plate 4 to achieve quick installation of the clamps 5. The above is the complete working principle of this utility model.

[0028] In this utility model, the installation, connection or setting methods of all the components mentioned above are common mechanical methods, and the specific structure, model and coefficient index of all the components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
