Problems solved by technology

[0003] At present, there are few test fixtures used on the universal testing machine in the market to fix the mandible model, and basically there is no test fixture that can fix the mandible model of different sizes and adjust its spatial position. Studying the biological damage of the mandible in crash conditions causes great inconvenience

Embodiment Construction

[0019] The following is attached Figure 1-4 Specific embodiments of the present invention will be described in detail.

[0020] Such as figure 1 As shown, this embodiment provides an adjustable spatial position fixture for fixing mandibular models of different sizes, including: a sliding adjustment mechanism, a rotation and up and down sliding adjustment mechanism.

[0021] Such as image 3 The sliding adjustment mechanism includes a sliding groove 1, a sliding slider 2, an upper chute 3, an upper and lower hexagon socket bolt 4, an upper sliding block 5, an upper chute and a column connecting bolt 6, and a column 7.

[0022] The sliding groove 1 can be fixed on the bottom of the testing machine with hexagon socket bolts. The connection between the upper sliding groove 3 and the sliding groove 1 is through the cooperation of the two sliding sliders 2 stuck in the sliding groove 1, and then tightened with the upper and lower groove socket bolts 4. pinned into lower slider 2...

Abstract

A spatial position adjustable clamp for fixing mandible models of different sizes comprises a sliding adjusting mechanism and a rotary and up-down sliding adjusting mechanism, and is characterized inthat the sliding adjusting mechanism comprises lower sliding chutes (1), lower sliding blocks (2), upper sliding chutes (3), upper and lower sliding chute hexagon socket bolts (4), upper sliding blocks (5), upper sliding chute-stand column connecting bolts (6) and a stand column (7), wherein the lower sliding chutes (1) are fixed to the bottom of a testing machine; the upper sliding chutes (3) andthe lower sliding chutes (1) are connected through the two lower sliding blocks (2) clamped in the lower sliding chutes (1) in a cooperative mode and then are screwed and fixed through the upper andlower sliding chute hexagon socket bolts (4); and the upper sliding chutes (3) and the stand column (7) are connected through the upper sliding blocks (5) clamped in the upper sliding chutes (3) and then are screwed and fixed through the upper sliding chute-stand column connecting bolts (6).

Description

technical field [0001] The invention mainly relates to the field of fixture design and manufacture, in particular to a fixture for fixing mandibular models of different sizes and adjustable spatial positions. Background technique [0002] In the field of biomechanics research, due to the irregular shape of the mandible, it is difficult to fix the mandible when performing mechanical tests on a universal testing machine (imitating the way the mandible is fixed in the human body), and when fixing the mandible, it is also necessary to consider The mandible works in various working conditions in the human oral cavity to adjust the spatial position of the model. At the same time, considering the differences in the size of the mandible in different groups of people, it is necessary to clamp and fix the mandible models of different sizes. [0003] At present, there are very few test fixtures used on the universal testing machine in the market to fix the mandible model, and basically...
