Description

Technical Field

[0001] The utility model belongs to the technical field of tool detection, and in particular relates to a tool wear test device. Background Art

[0002] Tool wear is a normal phenomenon during the machining process. In order to understand the wear resistance of the tool, a wear test will be conducted on it.

[0003] The Chinese utility model patent application number CN202222184932.9 (publication number CN218444959U) discloses a shield machine tool wear tester. Two clamping rods are provided on the base. The inner sides of the clamping rods are rotatably connected to the clamping plates. A fixed frame is vertically installed at one end of the base. The top of the fixed frame is movably connected to an L-shaped adjustment frame through a clamping mechanism. The adjustment frame is invertedly connected to a hydraulic rod. The telescopic end of the hydraulic rod is mounted with a test roller through a mounting frame. The spacing between the adjustment frame and the fixed frame can be adjusted according to the size of the clamped shield machine tool, so that the test roller can be adjusted to a suitable height to avoid its use being restricted. This makes the shield machine tool wear tester suitable for wear testing of shield machine tools of most sizes.

[0004] Since cutting tools are used in different scenarios, they will be worn by different materials. When the above patent is used, it is not convenient to replace the test material, which limits the experimental results. Utility Model Content

[0005] In view of this, the utility model provides a tool wear test device, which is used to solve the technical problem that the tool will be worn by different materials due to different usage scenarios, and it is inconvenient to replace the test material, which will lead to limited experimental results.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a tool wear experimental device, which comprises a workbench, a fixing frame vertically mounted on one end of the workbench, an L-shaped adjustment frame movably connected to the top of the fixing frame through a clamping mechanism, a hydraulic rod invertedly connected to the adjustment frame, wherein a support plate is fixedly mounted on the telescopic end of the hydraulic rod;

[0008] Four slides are provided on the bottom wall of the support plate, and two adjacent slides are symmetrically arranged about the horizontal axis and the vertical axis of the support plate respectively. Slide blocks are slidably connected in the slides, and a sheet material rack with a right-angle structure is fixedly installed on the bottom of the slider. An extrusion plate is vertically slidably connected in the sheet material rack, and a sheet material is clamped between the extrusion plate and the inner top wall of the sheet material rack.

[0009] On the basis of the above technical solution, the tool wear test device of the present invention can also be improved as follows:

[0010] Furthermore, a plurality of threaded holes are provided on the bottom wall of the sheet material rack, threaded rods are threadedly connected in the threaded holes, and the extrusion plates are fixedly mounted on the top ends of the threaded rods.

[0011] Furthermore, the inner walls of the ends of the sliders that are close to each other are fixedly mounted with fixed ends of the cylinders, and the movable ends of the cylinders are fixedly connected to the sliders.

[0032] Four slides 21 are provided on the bottom wall of the support plate 2. Two adjacent slides 21 are symmetrically arranged about the horizontal axis and the vertical axis of the support plate 2. Slide blocks 22 are slidably connected in the slides 21. The bottoms of the slide blocks 22 are fixedly installed with sheet material racks 23 with a right-angle structure. An extrusion plate 27 is vertically slidably connected in the sheet material rack 23. The sheet material is clamped between the extrusion plate 27 and the inner top wall of the sheet material rack 23.
