Description

Technical Field

[0001] The utility model relates to the technical field of blade wear testing, in particular to a blade wear testing device. Background Art

[0002] Before a blade leaves the factory, it is necessary to test the blade's edge wear. When a blade cuts an object, the blade's edge will wear out. Therefore, the blade can be used to cut objects continuously. When the blade's edge is worn, cutting objects becomes more difficult. Therefore, the blade wear is tested by cutting objects. Currently, the blade is manually cut on the surface of the object, and the wear of the blade is judged by the force felt. This method is inefficient and inaccurate. Utility Model Content

[0020] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] like Figures 1 to 4 As shown, an embodiment of the present application provides a blade wear testing device for a blade, comprising a base 10, a frame 11, a lifting structure 12, a first slider 13, a pressure sensor 14, a blade clamping structure 15 for clamping a blade 33, and a standard fixing structure 16 for fixing the rear end of a standard sample 32; the base 10 is provided with an X-axis guide rail 17, the blade clamping structure 15 is slidably connected to the X-axis guide rail 17, a support frame 18 is provided above the base 10, the support frame 18 is arranged directly below the blade clamping structure 15, the support frame 18 is used to support the front end of the standard sample 32, the first slider 13 is slidably connected along the lifting structure 12, the first slider 13 is connected to the blade clamping structure 15 through the pressure sensor 14, and the lifting structure 12 drives the first slider 13 to slide up and down, so that the blade 33 cuts the standard sample 32.

[0022] The standard sample fixing structure 16 is used to fix the rear end of the standard sample 32. The standard sample fixing structure 16 slides along the X-axis guide rail 17, and the front end of the standard sample 32 extends directly below the blade 33. The lifting structure 12 drives the first slide 13, the pressure sensor 14, and the blade clamping structure 15 to slide downward. The blade 33 cuts the standard sample 32. The pressure sensor 14 can detect the pressure. The lifting structure 12 continuously drives the blade clamping structure 15 up and down. When the pressure sensor 14 detects that the pressure reaches a predetermined value, it indicates that the blade 33 is worn. This allows for convenient and rapid detection of blade wear.

[0023] The first slider 13 is provided with a slide rail 19, and the blade clamping structure 15 is slidably connected to the slide rail 19. The top of the pressure sensor 14 is connected to the first slider 13, and the bottom is connected to the top of the blade clamping structure 15. The blade clamping structure 15 can slide along the slide rail 19, and the blade clamping structure 15 slides relatively stably. The standard sample 32 continuously extends directly below the blade clamping structure 15, and the blade 33 continuously cuts the standard sample 32. The pressure sensor 14 continuously detects pressure. When the pressure sensor 14 detects that the pressure reaches a predetermined value, it indicates that the cutting edge of the blade 33 is worn.

[0024] The support frame 18 includes two parallel vertical support frames 20 and a horizontal support plate 21 disposed between the two vertical support frames 20. The horizontal support plate 21 defines a through slot 22 that is parallel to the blade clamping structure 15. A standard sample 32 continuously extends toward the underside of the blade clamping structure 15, and a blade 33 continuously cuts the standard sample 32. After the blade 33 cuts the standard sample 32, it slides into the through slot 22, preventing the blade 33 from cutting the horizontal support plate 21.

[0025] A guide channel 23 is provided above the horizontal support plate 21, and the front end of the standard sample 32 moves to the horizontal support plate 21 along the guide channel 23. The guide channel 23 plays a guiding and positioning role, preventing the standard sample 32 from slipping during the cutting process of the blade 33.

[0026] The blade wear testing device further includes a second slider 24 and a Y-axis guide rail 25. The lifting structure 12 is connected to the second slider 24, which is slidably connected to the Y-axis guide rail 25. The second slider 24 slides along the Y-axis guide rail 25 to facilitate adjustment of the position of the blade clamping structure 15 in the Y-axis direction.

[0027] The blade clamping structure 15 includes a fixed plate 26 and a clamping block 27. The top of the clamping block 27 is fixedly connected to the surface of the fixed plate 26. A clamping groove for clamping the blade 33 is formed between the fixed plate 26 and the clamping block 27. The blade 33 is clamped in the clamping groove, which facilitates the replacement of the tool.

[0028] The standard specimen retaining structure 16 comprises a sliding frame 29, two clips 30, and a clamping structure 31. The sliding frame 29 is slidably connected to the X-axis guide rail 17. The two clips 30 are arranged parallel to the top of the sliding frame 29. A fixing groove is formed between the two clips 30, and the rear end of the standard specimen 32 is fixed in the fixing groove. The clamping structure 31 is used to clamp the rear end of the standard specimen 32. The position between the two clips 30 and the sliding frame 29 is adjustable, facilitating the replacement of standards 32 of different sizes. The rear end of the standard specimen 32 is positioned between the two clips 30 and then clamped by the clamping structure 31.

[0029] The above is a specific implementation of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
