For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0044] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0045] like Figure 1-9As shown, a hardness testing device for automobile parts includes: a workbench 1 for placing automobile parts; a slide seat 2, which is slidably arranged on the workbench 1, and after the slide seat 2 slides, it approaches or moves away from the automobile parts, and the middle part of the slide seat 2 has a mounting hole 2021; a sleeve 3, which is rotatably arranged in the mounting hole 2021; a mounting frame 4, which is arranged in the sleeve 3, and the mounting frame 4 has a plurality of long holes 401; a hydraulic cylinder 5, which is slidably arranged on the mounting frame 4 along the radial direction of the sleeve 3, and the hydraulic cylinder 5 has an output end 501; a locking member 6, which passes through the long hole 401 and is used to fix the hydraulic cylinder 5; a pressing head 7, which is arranged on the output end 501 and is used to abut on the automobile part.

[0046] When in use, place the auto parts on the workbench 1. When the auto parts detection position is not in the middle, the slide 2 slides to the top of the auto parts, the hydraulic cylinder 5 is located at a position radially deviated from the axis, and then the sleeve 3 is rotated to drive the hydraulic cylinder 5 to rotate and adjust the position so that the pressure head 7 is opposite to the detection position. Turn on the hydraulic cylinder 5 to press down and perform the detection. When a large number of tests are performed on the same auto parts, there is no need to adjust the position of the pressure head 7 each time. After adjusting the position, slide the slide 2 closer to or away from the auto parts each time. After the slide 2 is away from the auto parts, it is convenient to replace the auto parts.

[0047] The locking member 6 can be a bolt and nut, the bolt passes through the long hole 401 and the hole position of the hydraulic cylinder 5, and the nut is locked after connection. The arrangement of the long hole 401 facilitates the adjustment of the position of the hydraulic cylinder 5 in the radial direction.

The observation holes 2011 can be in a strip shape and can be arranged vertically to facilitate observation of the position of the internal pressing head 7, so that the pressing head 7 can be observed from multiple directions to be aligned with the automobile parts. The highest position of the pressing head 7 can be lower than the lower end of the sleeve 3. Both vertical side plates 201 can have observation holes 2011.

[0058] Furthermore, it also includes: a plug-in block 14, which is plugged into one of the observation holes 2011, and the plug-in block 14 is opposite to the pressure head 7; there are a plurality of indicator seats 15, and the indicator seats 15 are slidably set on the side of the workbench 1 parallel to the sliding direction of the slide 2, and the indicator seat 15 is located next to the slide 2. The indicator seat 15 has an indicator plate 1501, and the indicator plate 1501 is used to be opposite to the detection position of the automobile parts. After the slide 2 slides, the plug-in block 14 is close to or away from the indicator plate 1501.

[0059] When in use, the plug-in block 14 is plugged into the observation hole 2011 and can be opposite to the position of the pressure head 7, so as to indicate the position of the pressure head 7 in the sliding direction of the slide 2. The position perpendicular to the sliding direction of the slide 2 can be observed from the left viewing angle. The indicator seat 15 slides on one side of the workbench 1 and can be opposite to the position of the automobile parts to be tested, so as to indicate the position in the sliding direction of the slide 2. When the slide 2 slides, when the plug-in block 14 and the indicator plate 1501 are just opposite, the pressure head 7 and the detection position can be indicated, and the operation is more convenient.
