[0030] Please see attached Figure 1-6The purpose of this embodiment is to provide a positioning fixture for orthodontic brackets, including: a first positioning fixture 1 and a second positioning fixture 2. The base 13 is connected to the support plate 15 through the connecting plate 14, and the first push rod 16 is installed on the support plate 15, and the first push rod 16 moves in the horizontal direction. The base 21 of the second positioning fixture 2 is connected to the second push rod 23 through the extension beam 22, and the second push rod 23 moves in the vertical direction. Preferably, the ends of the first push rod 16 and the second push rod 23 are both provided with positioning ends 24, which are used to expand the contact area with the limited member and improve the stability of the limit.

[0031] Among them, a lower limit block 12 is provided on the side of the base 13 of the first positioning fixture 1 close to the second positioning fixture 2, and the lower limit block 12 is slidably connected to the movable block 110. A first push rod 16 is provided on the side of the base 13 of the first positioning fixture 1 away from the second positioning fixture 2, and the first push rod 16 pushes the movable block 110 to move in the horizontal direction. A through groove 117 is formed inside the lower limit block 12. A support block 114 is also provided on the lower limit block 12, and a limit stopper 115 is provided on one side of the top of the support block 114; the support block 114 and the through groove 117 are slidably connected to the movable block 110. The first push rod 16 pushes the movable block 110 to move along the support block 114 and the through groove 117. In this embodiment, a limit column to prevent the movable block 110 from detaching from the through groove 117 can also be provided on the bottom surface of the through groove 117, which is not shown in the drawings.

[0032] Furthermore, a mounting hole 118 is provided at one end of the support block 114 close to the first push rod 16, and a spring 116 is provided in the mounting hole 118, and the two ends of the spring 116 are respectively connected to the support block 114 and the movable block 110. When the first push rod 16 is retracted, the spring 116 pushes the movable block 110 away from the bracket, making it easier to remove the bracket.

[0033] It should be noted that an angle positioning block 19 is also provided on the base 13, and the angle positioning block 19 is located in a groove formed at the top corner of the lower limit block 12. The height of the angle positioning block 19 is greater than the height of the support block 114. Since the angle positioning block 19 and the limit stopper 115 protrude from the top surface of the support block 114, a positioning space is provided for the mesh bottom 112 of the bracket. After the mesh bottom 112 is positioned, the bracket body 111 does not contact the angle positioning block 19, the limit stopper 115 and the movable block 110, and does not contact during the process of the bracket body 111 being pushed for testing, which facilitates the measurement of welding strength.

[0034] In addition, an upper limit block 11 is arranged above the lower limit block 12, and the second push rod 23 of the second positioning fixture 2 moves in the vertical direction to limit the upper limit block 11 on the lower limit block 12. One or more guide rods 17 are installed on the lower limit block 12, and the upper limit block 11 can be quickly installed by cooperating with the guide holes on the upper limit block 11.

[0035] A limiting slide groove 113 is formed in the upper limit block 11 in the welding strength measurement system of the positioning fixture for orthodontic brackets, and a test block 18 is slidably arranged in the limiting slide groove 113. The mesh bottom 112 of the bracket is placed on the support block 114, and the mesh bottom 112 is limited by the movable block 110, the limiting block 115, and the angle positioning block 19. The test block 18 moves horizontally along the limiting slide groove 113 to push the bracket body 111 welded to the mesh bottom 112.

[0036] As mentioned above, the mesh bottom 112 of the bracket is placed on the support block 114. The support block 114 cooperates with the movable block 110, the limit stop block 115, and the corner positioning block 19 to quickly limit the mesh bottom 112. The test block 18 moves horizontally along the limit slide groove 113 in the upper limit block 11 to push the bracket body 111 welded to the mesh bottom 112, and the welding strength between the bracket body 111 and the mesh bottom 112 can be quickly measured.

[0037] Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model should be included in the protection scope of this utility model.
