AI Technical Summary
In the prior art, when a bolt is not pre-screwed into a threaded hole, it is easy to be screwed in at an angle, resulting in jamming. In particular, it cannot be discovered in time during automatic loading and assembly, which affects assembly efficiency.
A bolt anti-tilt function test device was designed, which included a bracket, a tightening device, an elastic device and a positioning pin. By simulating the situation where a bolt was screwed into an internal threaded part at an angle, the anti-tilt function of the bolt was tested and the bolts that met the requirements were screened out.
Effectively screen out bolts with anti-tilt function to prevent unqualified bolts from entering the assembly site, improve assembly efficiency, and reduce the time for subsequent assembly errors.

Description
TECHNICAL FIELD
[0001] The utility model relates to bolt test technical field, concretely is a kind of bolt anti-inclination function test device. BACKGROUND
[0002] Now automobile fastener assembly speed is faster, if bolt is not pre-wrenched into thread hole, there is bolt oblique spin and inner thread jamming situation, especially when meeting this condition when automatic feeding assembly, cannot find in time, drag assembly progress.Therefore there is a series of anti-inclination bolt in industry.For the anti-inclination function of bolt needs a set of test device to verify its effectiveness, to avoid the bolt that does not meet the function circulates to assembly site, affect assembly efficiency. SUMMARY
[0003] To solve the problems presented in the above background art, the purpose of the utility model is to provide a kind of bolt anti-inclination function test device, support is equipped with horizontal part, vertical part, the horizontal part upper end is equipped with tightening device, the support one side is equipped with base, the base upper end is equipped with nut fixed support, the nut fixed support one side is equipped with elastic device fixed bolt one side, the elastic device fixed bolt one other side is equipped with elastic device one end, the elastic device other end is connected elastic device fixed bolt two.
[0004] The other side of the nut fixed support is provided with a positioning pin, and the nut fixed support is rotatably connected with the base by the positioning pin.
[0005] The nut fixed support is obliquely arranged, and an inclination angle of 5-10 degrees is generated with the base.
[0006] The nut fixed support is provided with a mounting groove at the center.
[0007] The other end of the elastic device fixed bolt two is fixed in the base.
[0008] The vertical part of the support is provided with a fixed bolt at the top end, and the fixed bolt fixes the horizontal part.
[0009] Compared with the prior art, the utility model can test whether the bolt has anti-inclination function, and select the bolt that meets the function adjustment to enter the use scene.Effective bolts are selected in advance, and the bolts that do not meet the requirements are eliminated to save the time of subsequent assembly error and improve the assembly efficiency. BRIEF DESCRIPTION OF DRAWINGS
[0010] Figure 1 It is the test device structural schematic view of the utility model.
[0011] See Figure 1, 1, tightening device, 2, anti-inclination bolt, 3 nut fixing support, 4, test nut, 5, positioning pin, 6, elastic device fixing bolt one, 7, elastic device fixing bolt two, 8, elastic device, 9, support, 10, fixing bolt, 11, base. DETAILED DESCRIPTION
[0012] The utility model will be further explained in accordance with the drawings below.
[0013] As Figure 1 shown, the support 9 is provided with a horizontal part and a vertical part, the horizontal part is provided with the tightening device 1 at the upper end, the tightening device 1 adopts a tightening shaft, one side of the support 9 is provided with the base 11, the upper end of the base 11 is provided with the nut fixing support 3, one side of the nut fixing support 3 is provided with the elastic device fixing bolt one 6, the other side of the elastic device fixing bolt one 6 is provided with one end of the elastic device 8, the other end of the elastic device 8 is connected with the elastic device fixing bolt two 7, and the elastic device 8 selects an elastic rubber band. The vertical part of the support 9 is provided with the fixing bolt 10 at the top end, and the fixing bolt 10 fixes the horizontal part.
[0014] The other side of the nut fixing support 3 is provided with the positioning pin 5, the nut fixing support 3 is rotatably connected with the base 11 through the positioning pin 5, and the movability of the nut fixing support 3 is ensured.
[0015] The nut fixing support 3 is arranged to be inclined, and an inclination angle of 5-10 degrees is formed between the nut fixing support 3 and the base 11, and the nut fixing support 3 is provided with a mounting groove at the center. When the anti-inclination bolt 2 is vertically placed into the tightening shaft, an inclination in the vertical direction is formed between the test nut 4 placed into the mounting groove in the nut fixing support 3, so as to simulate the situation that the bolt is inclined and screwed into the internal threaded part.
[0016] The other end of the elastic device fixing bolt two 7 is fixed in the base 11, and the stability of the elastic device is ensured.
[0017] In use, the tightening device 1 is rotated, under the action of the tightening torque, the anti-inclination bolt 2 is gradually screwed into the test nut 4, under the action of the threaded cooperation, the test nut 4 is gradually perpendicular to the anti-inclination bolt 2, and the test nut fixing support 3 is lifted up, and due to the existence of the elastic device 8, the test nut fixing support 3 will be subjected to a pulling force in this process, and a rotating torque in the correcting direction - the correcting torque M is generated for the anti-inclination bolt 2, wherein M=F of the elastic device * L of the force arm.
[0018] For the anti-inclination bolt 2, the test nut fixing support 3 can be normally lifted up under the correcting action, and the bolt and the nut thread are not damaged. For the parts that do not meet the anti-inclination function, the bolt will be stuck in the test nut 4 or slip, and the test nut 4 cannot be corrected, so it does not pass the test of the device.
