[0022] Refer to Figures 1 - 6, A wear resistance detection device for high-speed steel, comprising a frame body 1 and a grinding plate 502. A vertical frame 2 is welded to the top of the frame body 1. A lifting placement frame 5 is inserted into the top of the frame body 1. A placement groove 501 for positioning and installing the grinding plate 502 is provided at the top of the lifting placement frame 5. An elevating drive assembly 6 for driving the lifting placement frame 5 to perform lifting operations is provided inside the frame body 1. Two side clamping frames 503 are detachably installed on the top of the lifting placement frame 5 by bolts, and the side clamping frames 503 limit the grinding plate 502, thereby facilitating the quick installation and fixation of the grinding plate 502. A locking assembly 7 for fixing the position of the lifting placement frame 5 is provided on the top of the frame body 1. Two horizontal guide rails 9 are fixed to one side of the vertical frame 2 by bolts. A cross-moving frame 3 is slidably connected between the two horizontal guide rails 9 through a sliding table. A rotary clamping assembly 4 for clamping and rotating the high-speed steel for wear resistance testing is provided at the bottom of the cross-moving frame 3. A cross-moving drive assembly 8 for horizontally wear resistance testing of the clamped high-speed steel is provided on one side of the vertical frame 2. During use, first, the high-speed steel is quickly clamped by the rotary clamping assembly 4, and the rotary clamping assembly 4 can be applicable to the clamping operations of high-speed steels with different diameters. Then, the elevating drive assembly 6 drives the lifting placement frame 5 to a specified position, and the grinding plate 502 is brought into contact with the bottom end of the high-speed steel quickly clamped by the rotary clamping assembly 4. At this time, it can be locked and fixed by the locking assembly 7. Then, the clamped high-speed steel can be rotated by the rotary clamping assembly 4, so as to realize the rotational friction experiment at the bottom end of the high-speed steel. Then, the cross-moving drive assembly 8 can drive the cross-moving frame 3 to reciprocate along the horizontal guide rail 9, so as to perform a horizontal friction experiment on the high-speed steel quickly clamped by the rotary clamping assembly 4. At the same time, the rotational friction experiment and the horizontal friction experiment can be carried out simultaneously, so as to realize different friction experiment combinations and make the experimental data more sufficient.

[0023] The rotary clamping assembly 4 in the present invention includes a lower mounting frame 402 fixed to the outer wall of the bottom of the cross-moving frame 3 by bolts. A chuck 403 for quickly clamping high-speed steels with different diameters is rotatably connected to the inside of the lower mounting frame 402 through a bearing. A rotary motor 401 for driving the chuck 403 to rotate around its axis is provided on the inner wall of the bottom of the cross-moving frame 3. The chuck 403 can quickly clamp high-speed steels with different diameters, and then by starting the rotary motor 401, the rotary motor 401 rotates to drive the chuck 403 to drive the high-speed steel to perform a rotating operation.

[0024] The transverse movement driving assembly 8 in the present invention includes a rotating disk 802 rotatably connected to one side of the vertical frame 2 through a bearing. One side of the rotating disk 802 is rotatably connected to a connecting arm 803 through an adjusting structure, and one end of the connecting arm 803 is rotatably connected to the transverse movement frame 3. On the other side of the vertical frame 2, there is a transverse movement driving motor 801 for driving the rotating disk 802 to rotate around its axis. The adjusting structure includes an adjusting groove 805 opened inside the rotating disk 802. An adjusting slider 804 rotatably connected to the connecting arm 803 is slidably connected in the adjusting groove 805. A plurality of equally spaced pin holes 806 are opened on one side of the rotating disk 802. A threaded hole 807 is opened inside the adjusting slider 804, and a screw 808 cooperating with the pin hole 806 is threadedly connected in the threaded hole 807. By starting the transverse movement driving motor 801, the rotation of the transverse movement driving motor 801 drives the rotation of the rotating disk 802. The rotation of the rotating disk 802 causes the connecting arm 803 to drive the transverse movement frame 3 to make a reciprocating movement along the first transverse guide rail 9. Then, the position of the adjusting slider 804 can be moved, and by rotating the screw 808, the screw 808 is inserted into one of the pin holes 806 along the threaded hole 807, so that the adjusting slider 804 is locked and fixed, thereby adjusting the distance of the reciprocating movement of the transverse movement frame 3 along the first transverse guide rail 9 to meet different friction detection requirements.

[0025] The lifting driving assembly 6 in the present invention includes an electric push rod 602 fixed inside the frame body 1 through bolts. The top end of the electric push rod 602 passes through the frame body 1 and is fixed to the lifting placement frame 5 through a disc spring 601. The locking assembly 7 includes a plurality of second transverse guide rails 705 fixed to the top of the frame body 1 through bolts. A pin frame 704 is slidably connected between adjacent two second transverse guide rails 705 through a slide table. A plurality of equally spaced card slots 703 cooperating with the pin frame 704 are opened on one side of a plurality of lifting rods of the lifting placement frame 5. A finger cylinder 701 is fixed to the top of the frame body 1 through bolts. Two sliders of the finger cylinder 701 are respectively fixed to the two pin frames 704 through connecting plates 702. During use, by starting the electric push rod 602, the electric push rod 602 extends to drive the lifting placement frame 5 and the grinding plate 502 to move upward to a specified height. At this time, the grinding plate 502 contacts the bottom end of the high-speed steel. At the same time, by starting the finger cylinder 701, the sliders of the finger cylinder 701 move outwards to drive the pin frame 704 to move outwards along the second transverse guide rail 705 through the connecting plate 702 and be fixed to the card slot 703, so that the position of the lifting placement frame 5 is fixed. When dynamic pressure needs to be applied, the locking and fixing state of the lifting placement frame 5 is released, and then the electric push rod 602 continues to extend. At this time, the disc spring 601 is stressed and shortened, thereby increasing the friction between the grinding plate 502 and the bottom end of the high-speed steel. Therefore, the friction between the grinding plate 502 and the bottom end of the high-speed steel can be dynamically adjusted through the extended length of the electric push rod 602 and the elastic force of the disc spring 601.

[0026] The present invention is used in the following steps: S1: First, the chuck 403 can quickly clamp high-speed steel with different diameters. S2: Then, by starting the electric push rod 602, the electric push rod 602 extends to drive the lifting placement frame 5 and the grinding plate 502 to move upward to a specified height. At this time, the grinding plate 502 contacts the bottom end of the high-speed steel. Meanwhile, by starting the finger cylinder 701, the slider of the finger cylinder 701 moves outward and drives the pin frame 704 to move outward along the second transverse guide rail 705 through the connecting plate 702 and is fixed to the card slot 703, so that the position of the lifting placement frame 5 is fixed. S3: Then, by starting the rotary motor 401, the rotary motor 401 rotates to drive the chuck 403 to drive the high-speed steel to perform a rotating operation, thereby realizing the rotating friction experiment on the bottom end of the high-speed steel. S4: Then, stop the rotation state of the rotary motor 401. Immediately afterwards, by starting the transverse movement drive motor 801, the transverse movement drive motor 801 rotates to drive the rotary disk 802 to rotate. The rotation of the rotary disk 802 causes the connecting arm 803 to drive the transverse movement frame 3 to perform a reciprocating movement along the first transverse guide rail 9. Then, the position of the adjustment slider 804 can be moved, and by rotating the screw 808, the screw 808 is inserted into one of the pin holes 806 along the threaded hole 807, so that the adjustment slider 804 is locked and fixed, and thus the distance of the reciprocating movement of the transverse movement frame 3 along the first transverse guide rail 9 is adjusted to meet different friction detection requirements. S5: At the same time, the rotary friction experiment and the transverse friction experiment can be carried out simultaneously, so as to realize different friction experiment combinations and make the experimental data more sufficient. S6: When dynamic pressure needs to be applied, the locking and fixing state of the lifting placement frame 5 is released, and then the electric push rod 602 continues to extend. At this time, the disc spring 601 is stressed and shortened, thereby increasing the friction force between the grinding plate 502 and the bottom end of the high-speed steel. Therefore, the friction force between the grinding plate 502 and the bottom end of the high-speed steel can be dynamically adjusted by the extension length of the electric push rod 602 and the elastic force of the disc spring 601.

[0027] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered to be within the scope described in this specification.

[0028] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
