[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0027] like Figure 1-4As shown, the present invention proposes a tool auxiliary tool, the tool holder mechanism includes a base plate 11, a recessed tool groove 12 is provided in the middle of the base plate 11, and a protective shell 13 is formed on the outside of the base plate 11.
[0028] The tool holder mechanism acts as a base during testing, and the base plate 11 is a supporting structure. The recessed guide groove 12 in the middle is used for placing the tool.
[0029] The track mechanism includes a track 21 mounted on the housing 13, a slide block 22 slidably mounted in the slot of the track 21, and a bracket 23 formed on the upper part of the slide block 22.
[0030] The adjusting mechanism includes a cylinder 31 mounted on a bracket 23, a movable piston rod 32 installed inside the cylinder 31, and a support plate 33 connected to the other end of the piston rod 32.
[0031] The testing mechanism includes a pressure plate 41 mounted on a support plate 33, and a protruding testing end seat 42 is formed on the lower part of the pressure plate 41.
[0032] It should be noted that the cutting groove 12 in the middle of the base plate 11 has a "V" structure. The cutting groove 12 adopts a "V" structure contour, which can adapt to different shaped knives, provide multi-point support, prevent the knife from shifting during clamping, and place the cutting edge of the knife into the cutting groove 12 to effectively prevent the blade from being exposed and cutting others.
[0033] In this embodiment, the cutting tool is placed in the tool groove 12, the slide block 22 on the sliding rail 21 is manually slidable, and the position of the bracket 23 is adjusted to one end so that the detection end seat 42 of the pressure plate 41 is aligned with the end of the cutting edge. The working cylinder 31 of the adjustment mechanism is activated, which drives the support plate 33 connected to the piston rod 32 to move, thereby driving the pressure plate 41 to move down. At this time, the detection end seat 42 is attached to the cutting edge of the cutting tool. The set pressure is applied by the drive of the cylinder 31. The adjustment mechanism can be adapted to the detection of cutting tools of different specifications and sizes.
[0034] The edge shape of the attached tool is detected by the detection end seat 42, and the tool edge is continuously detected by the stable movement of the track mechanism, thereby improving the efficiency of edge shape detection.
[0035] like Figure 3 As shown, the base plate 11 has L-shaped protective shells 13 at both ends. The L-shaped protective shells 13 protect the tool groove 12 area and provide a base for the mounting rail 21. The protective shells 13 and the tool groove 12 have the same slope at their attachment points, and their contact surfaces have matching tilt angles, ensuring that the tool is aligned with the pressure plate 41 when placed, reducing detection errors.
[0036] It is understandable that the track 21 is set on the upper part of any of the protective shells 13, and the bracket 23 set above the track 21 is a "triangular" structure; the track can be installed on the left or right protective shell, which facilitates the flexible installation of the track 21. The triangular structure of the bracket 23 can provide stable support, improve the stability of the slide 22 when it moves, and prevent vibration from interfering with the detection.
[0037] It is understandable that the pressure plate 41 and the knife groove 12 are tilted at the same angle, and the tilt angle of the pressure plate 41 is consistent with that of the knife groove 12, so as to ensure that the cutting edge is exposed at a fixed angle during the test, which is convenient for observation.
[0038] The pressure plate 41 moves synchronously with the piston rod 32. When the cylinder 31 drives it, the pressure plate 41 can accurately follow the up and down movement to achieve synchronous control of pressing or separating, ensuring consistent pressure during the testing process.
[0039] As an example of testing: The tool to be tested is held between the pressure plate 41 and the tool groove 12, and the testing end seat 42 is attached to the tool to be tested; the tool is held between the pressure plate 41 and the tool groove 12, and the testing end seat 42 is specifically pressed against the cutting edge area of the tool. The contact allows for the application of light pressure to form a continuous contact line. If there is wear, gaps will appear.
[0040] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
