DETAILED DESCRIPTION

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a pin quality detection device, comprising:

The lower bottom surface is provided with an electromagnetic block for use, and the lower bottom surface of the electromagnetic block is magnetically connected with a collision test block 9, and the electromagnetic adsorption module 8 and the collision test block 9 are both arranged directly above the test seat 3, and the top of the threaded rod 4 is fixedly connected with a rotating handle for easy operation by the staff, and the inner side wall of the machine body 1 is fixedly provided with a scale 16, and the scale 16 is vertically arranged for accurate measurement of the test height;

[0024] A cleaning component is arranged in the body 1, and the cleaning component includes a driving wheel 10 fixedly connected to the threaded rod 4 in the circumference. Two rotating shafts 11 are rotatably connected to the top surface of the body 1 through bearings. The two rotating shafts 11 are fixedly connected to the circumference of driven wheels 12. Belts 13 are wound between the two driven wheels 12 and the driving wheel 10. The radius of the driving wheel 10 is larger than the radius of the driven wheel 12, thereby improving the transmission ratio. The two rotating shafts 11 are both penetrated and rotatably connected to the bottom surface of the partition 2. The bottom ends of the two rotating shafts 11 are fixedly connected to blowing fan blades 14. The two blowing fan blades 14 are both located below the partition 2. A plurality of ventilation holes 15 are provided on the upper surface of the partition 2. The plurality of ventilation holes 15 are arranged around the two rotating shafts 11, so that the blowing fan blades 14 can generate airflow normally.

[0025] The detailed working process of the utility model is as follows:

[0026] When testing is required, first fix the pin to be tested on the test seat 3, and then use the electromagnetic adsorption module 8 to cooperate with the electromagnetic block to adsorb the collision test block 9. After completion, turn the handle to rotate the threaded rod 4, and the nut 5 will be threadedly engaged with the threaded rod 4 under the restriction of the two guide rods 7 and the partition 2, and then move up and down along the threaded rod 4, so that the collision test block 9 is driven up and down by the electromagnetic adsorption module 8 and the electromagnetic block to adjust the collision intensity, and the collision height is measured by the scale 16. The mass of the collision test block 9 is also known, and the mass of the electromagnetic block is also known. Then, the electromagnetic adsorption module 8 contacts the electromagnetic block 1, so that the electromagnetic block and the collision test block 9 can be made to fall freely, and a collision test is performed with the pin to be tested to test its surface hardness;

[0027] When the test height is adjusted, the threaded rod 4 rotates, thereby driving the driving wheel 10 to rotate. The driving wheel 10 rotates through the belt 13 to drive the two driven wheels 12 and the rotating shaft 11 to rotate, thereby driving the two blowing fan blades 14 to rotate, and the surface of the pin to be tested is cleaned, so that the test result is more accurate.
