Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of size detection, in particular to a clamping tool for detecting the torsion resistance of a bridge frame. Background Art
[0002] A bridge is a component made of metal or ceramic material, and its structure is similar to the shape of a bridge. It is mainly used to connect multiple dental implants. In order to ensure the completeness and stability of the bridge and evaluate multiple performance parameters of the material, an implant torsion testing machine is usually used to perform a torsion test on the bridge. In the prior art, a torsion testing machine is usually used to clamp one end of the bridge, and the abutment connected to the other end of the bridge is also clamped. One end is rotated to measure the maximum torque. However, since the bridge is a personalized customized product without a fixed shape, it is difficult to clamp both ends of the bridge when clamping, which makes the detection difficult. Utility Model Content
[0003] In view of the deficiencies of the above-mentioned related prior arts, the present application provides a bridge frame torsional resistance detection clamping tool, which is convenient for clamping bridge frames of different shapes, facilitates torsion testing, reduces the difficulty of detection, and has strong practicality.
[0004] In order to achieve the above purpose, the utility model adopts the following technologies:
[0005] A clamping tool for detecting the torsion resistance of a bridge frame comprises a base and a fixing plate.
[0006] A chuck is provided on the bottom surface of the base, and a detachable positioning pin is passed through the center of the top surface. When in use, one end of the chuck is connected to the torsion testing machine, the upper end of the positioning pin is connected to the bottom of the bridge through a thread, the top of the bridge is connected to the base through a thread, and one end of the base is connected to the torsion testing machine; there are two fixed plates, which are symmetrically arranged on both sides of the top surface of the base and move along the length direction of the base to clamp the bridge.
[0007] Furthermore, mounting plates are provided on both sides of the base, the mounting plates are connected to the base by screws, threaded holes are provided on the sides of the mounting plates, a push rod is passed through the threaded holes, and one end of the push rod abuts against the outer side of the fixing plate.
[0008] Furthermore, two vertically penetrating slide grooves are provided on both sides of the length direction of the base, and the length direction of the slide groove is parallel to the axis of the top rod. Bolts are passed through both ends of the fixing plate, and the lower ends of the bolts pass through the slide grooves and are locked with nuts.
[0009] Furthermore, the base is provided with a through hole, the axis of the through hole and the axis of the base are located on the same straight line, and the positioning pin is passed through the through hole.
[0010] Furthermore, the inner cross-section of the fixing plate is triangular, and the edge is arc-shaped.
[0011] The beneficial effect of the utility model is that the bridge frame can be placed on the base by means of the positioning pins, and then the two sides of the bridge frame can be positioned and clamped by means of the fixing plates, so that bridge frames of different shapes can be clamped, which is convenient for torsion testing and reduces the difficulty of detection. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present invention.
[0013] Figure 1 It is a schematic diagram of the overall structure of an embodiment of the present application. DETAILED DESCRIPTION
[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.
[0015] like Figure 1 As shown, this example provides a bridge frame torsional resistance detection clamping tool, including: a base 1 and a fixing plate 2.
[0016] A chuck 11 is provided on the bottom surface of the base 1, and a detachable positioning pin 12 is passed through the center of the top surface. When conducting a torsion test, one end of the chuck 11 is connected to the torsion testing machine, the upper end of the positioning pin 12 is connected to the bottom of the bridge through a thread, and the top of the bridge is connected to the base through a thread, and one end of the base is connected to the torsion testing machine; there are two fixing plates 2, which are symmetrically arranged on both sides of the top surface of the base 1, and move along the length direction of the base 1 to clamp the bridge. At this time, you only need to rotate this end of the chuck 11 or this end of the base to complete the torsion test.
[0017] Specifically, two upper and lower sliding grooves 15 are provided on both sides of the length direction of the base 1. The length direction of the sliding groove 15 is parallel to the axis of the top rod 3. Bolts 21 are passed through both ends of the fixed plate 2. The lower end of the bolt 21 passes through the sliding groove 15 and is locked with a nut. After the position of the fixed plate 2 is adjusted, the inner side of the fixed plate 2 is contacted with the bridge frame, and then the bolt 21 is locked with a nut to achieve the positioning of the fixed plate 2 and complete the clamping of the bridge frame.
[0018] Specifically, mounting plates 13 are provided on both sides of the base 1, and the mounting plates 13 are connected to the base 1 by screws. Threaded holes 14 are provided on the sides of the mounting plates 13, and a push rod 3 is passed through the threaded holes 14. One end of the push rod 3 abuts against the outer side of the fixed plate 2. When the fixed plate 2 is in a free state, the push rod 3 can be rotated to push the fixed plate 2 toward the center of the base 1, so that the fixed plate 2 contacts with the bridge frame.
[0019] Specifically, the base 1 is provided with a through hole 16, the axis of the through hole 16 is located on the same straight line as the axis of the base 1, and the positioning pin 12 is passed through the through hole 16, so as to ensure that after the bridge frame is clamped, the base and the bridge frame planting point are coaxial, thereby ensuring accurate detection.
[0020] Specifically, the inner cross-section of the fixing plate 2 is triangular, and the edge is arc-shaped, so that it is more convenient to clamp the bridge.
[0021] Since the above are only preferred embodiments of the present invention and are not intended to limit the present invention, it is obvious that those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
