Problems solved by technology

[0002] The surface of aluminum alloy wheels usually undergoes surface treatment including chemical or physical means such as coating, coating, electroplating and polishing to achieve decorative and protective performance. The protective performance is mainly achieved through tests, including salt spray test, composite corrosion test, steam Three-proof tests such as spray test and wet mud test, as well as conventional tests such as adhesion, need to draw lines on the surface of the aluminum alloy wheel sample block before the test. The conventional method is to saw the aluminum alloy wheel hub into a sample that meets the test conditions before the test. Then put the sample block on the platform and use the scribing tool (specified cutter, ruler and scriber) to draw lines (straight lines or cross lines and grid lines with a certain angle) on the surface of the sample block according to the corresponding standards, and operate When the sample block is easy to slide, the marking line is skewed, resulting in the waste of the sample block

Embodiment 1

[0024] Combined with the manual Figure 1-3 Example 1 of the present application is described, a fixture for marking and fixing an aluminum alloy wheel anticorrosion test sample, including a fixture base 1 , a first chute 2 , a second chute 3 , and an adjustable pressing assembly. The left side and the right side of the fixture base 1 are provided with a first chute 2 and a second chute 3, the first chute 2 on the left side and the first chute 2 on the right side are symmetrically arranged on the outside, and the left side The second chute 3 and the second chute 3 on the right side are symmetrically arranged on the inside; on the first chute 2 and the second chute 3 on the left side, more than two adjustable pressing assemblies are arranged, and on the right side More than two adjustable pressing assemblies are arranged on the first chute 2 and the second chute 3 .

[0025] The adjustable pressing assembly includes a clamping support 4, a support positioning bolt 5, a support...

Embodiment 2

[0029] The difference between embodiment 2 and embodiment 1 lies in that the direction in which the locking bolt and the locking nut connect the clamping plate and the grip is different. Specifically in embodiment 2: the locking bolt vertically passes through the clamping plate and the gripper, the gripper can rotate in the horizontal plane relative to the clamping plate, and the orientation of the grasping hand can be adjusted in the horizontal plane. All the other technical features are the same as in Example 1.

[0030] The locking device in the present application is not limited to locking bolts and locking nuts, and in other embodiments, the locking device can be in other ways, such as being clamped by a clamp.

Abstract

The invention relates to the technical field of fixing clamps, and provides an aluminum alloy wheel sample block fixing clamp which comprises a clamp base, a first sliding groove, a second sliding groove and adjustable compressing assemblies. The adjustable compressing assemblies can slide and adjust the direction along the first sliding groove and the second sliding groove, one test sample blockis compressed by compressing at least four points, the directions of grippers can be adjusted, the aluminum alloy wheel sample block fixing clamp can better adapt to test sample blocks of different sizes and shapes, the fixing effect is good, and the universality is high; in addition, the pressing force on pressing plates and the grippers can be adjusted by adjusting pressing force adjusting nuts,so that the clamp can adapt to surfaces with different hardness; and rubber pads on the grippers can prevent damage to the surfaces of the test sample blocks.
