Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, and in particular to a push-pull universal clamping orthodontic bracket welding fixture. Background Technology

[0002] Early orthodontic bracket welding fixtures were custom-made for bracket bodies with different torques and bracket base plates with different shapes. It took about 80 fixtures to weld a complete set of brackets, which wasted a lot of manpower and resources. After the fixtures were worn out, they had to be discarded and reprocessed, resulting in high usage and maintenance costs.

[0003] However, the above method has a prominent hardware structure problem. When the main body of the bracket with a torque of ±15° or greater is placed on its corresponding inclined tooling, there will inevitably be a large height difference. The perfect welding state should be that the laser is focused on a horizontal position point at a certain fixed angle. Such a height difference will directly change the laser focal length, resulting in poor welding. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a push-pull universal clamping orthodontic bracket welding fixture, which solves the technical problem that when a bracket body with a torque of ±15° or greater is placed on a fixture that is tilted, there will inevitably be a large height difference. The perfect welding state should be that the laser is focused on a horizontal position at a certain fixed angle. Such a height difference will directly change the laser focal length and cause poor welding.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A push-pull universal clamping orthodontic bracket welding fixture includes a retaining platform, a push-pull clamping part at one end of the retaining platform, a Z-axis lifting platform at one end of the retaining platform, an extendable angle adaptive mechanism on the retaining platform, a base fixedly connected to the side end of the retaining platform, and a fixing pin fixedly connected to one end of the base.

[0007] Preferably, the push-pull clamping part is fixedly connected to the stationary platform, and the Z-axis lifting platform is also fixedly connected to the stationary platform.

[0008] Preferably, the push-pull clamping part includes a push-pull handle and a pressure rod. The push-pull handle is fixedly connected to a fixing pin, and the pressure rod is also fixedly connected to a fixing pin. A connecting rod is provided at the lower end of the push-pull handle, and the lower end of the connecting rod is fixedly connected to the upper end of the pressure rod.

[0009] Preferably, a lead screw is fixedly connected to the lower end of the Z-axis lifting platform, a worm gear is fixedly connected to the lower end of the lead screw, a worm is meshed with the side end of the worm gear, and a knob is fixedly connected to one end of the worm.

The spring is located inside the threaded sleeve, the convex ball head post is connected to the threaded sleeve, and the concave ball head is connected to the convex ball head post.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. It has the function of adapting to different angle torque and different angle shaft tilt of the support body, so there is no need to design a large number of tooling reserves.

[0013] 2. Its adaptive angle section can ensure that the welding part after the tray is pressed is at the same height as the laser focus, thus avoiding the phenomenon of poor welding caused by the change of height of the tray welding part during laser welding.

[0014] 3. By adjusting the Z-axis lifting platform, the height of the groove welding part is made to coincide with the laser focus, thus avoiding the situation where the welding strength is unstable due to adjusting the laser focus height. Attached Figure Description

[0022] This application provides a push-pull universal clamping orthodontic bracket welding fixture, which effectively solves the technical problem that when a bracket body with a torque of ±15° or greater is placed on a corresponding inclined fixture, there will inevitably be a large height difference. The perfect welding state should be that the laser is focused on a horizontal position point at a certain fixed angle. Such a height difference will directly change the laser focal length, resulting in poor welding. It has the function of adapting to different angle torques and different angle axial tilt bracket bodies, eliminating the need to design a large number of fixtures for reserve.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the problem that when a bracket body with a torque greater than or equal to ±15° is placed on its corresponding inclined tooling, there will inevitably be a large height difference. A perfect welding state requires the laser to be focused at a horizontal position at a fixed angle. This height difference directly changes the laser focal length, resulting in poor welding. The overall approach is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a push-pull universal clamping orthodontic bracket welding fixture, including a retaining platform 1, a push-pull clamping part at one end of the retaining platform 1, a Z-axis lifting platform 13 at one end of the retaining platform 1, a telescopic angle adaptive mechanism on the retaining platform 1, a base 2 fixedly connected to the side end of the retaining platform 1, a fixing pin 3 fixedly connected to one end of the base 2, the push-pull clamping part fixedly connected to the retaining platform 1, and the Z-axis lifting platform 13 also fixedly connected to the retaining platform 1. It has the function of adaptively adjusting the torque and the main body of the orthodontic bracket at different angles, eliminating the need to design a large number of tooling reserves.

[0026] The push-pull clamping part includes a push-pull handle 4 and a pressure rod 6.

A worm 14 is meshed with the side end of the worm gear 11. A knob 15 is fixedly connected to one end of the worm gear 14. Rotating the knob 15 causes the worm gear 14 to drive the worm gear 11 to rotate. The rotational motion of the worm gear 11 is transmitted to the lead screw 12, causing the lead screw 12 to perform linear lifting motion, thereby realizing the lifting motion of the Z-axis lifting platform 13. Its adaptive angle part can make the welding part after the slot is clamped at the same height as the laser focus, avoiding the phenomenon of poor welding caused by the change of height of the slot welding part during laser welding.

[0038] Worm gear 11: Its side end meshes with the worm 14, transmitting the rotational motion to the lead screw 12 to realize the linear lifting motion of the lead screw 12;

[0039] Lead screw 12: Its lower end is connected to worm gear 11, and it performs linear lifting motion under the drive of worm gear 11, thereby realizing the lifting motion of Z-axis lifting platform 13;

[0041] Worm 14: One end is fixedly connected to knob 15 and meshes with worm wheel 11. When rotated, it drives worm wheel 11 to rotate, thereby realizing the lifting and lowering adjustment of Z-axis lifting platform 13;
