[0002] Tool passivation refers to the process of deburring, smoothing, and polishing the sharpened tool to improve its quality and extend its service life. There are also other reasons, such as when the blade of the tool is too sharp but does not actually need to be as sharp, the blade also needs to be passivated. This process is usually carried out after the tool is fine-ground and before coating. It aims to solve the defects of micro-notches on the tool edge after sharpening, reduce or eliminate its edge value, and achieve a smooth and flat effect that is both sharp and durable. However, most of the existing tool passivation processes are performed manually, and it is impossible or difficult to passivate multiple tools at the same time, which is inefficient, and manual operation may cause deviations in the passivation effect. Therefore, there is a need for a tool passivation device. Utility Model Content

DETAILED DESCRIPTION

[0016] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0017] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0019] Figure 1-Figure 3 The diagram shows the entire structure of a tool passivation device of the present invention. Figure 1-Figure 3 , a tool passivation device in this embodiment includes a base 100, a slide 200 and a first reciprocating drive member 300 for pushing the slide 200 to move back and forth are horizontally slidably installed on one side of the upper part of the base 100, a gear bar 400 and a second reciprocating drive member 500 for driving the gear bar 400 to move left and right are horizontally slidably installed on the upper end of the slide 200 along its length direction, a plurality of half gear plates 600 meshing with the gear bar 400 are rotatably installed at the front end of the slide 200 along its length direction, a connecting rod 610 is fixed to the half gear plate 600 on the opposite side of the gear bar 400, a clamp 620 for clamping the tool is provided at the front end of the connecting rod 610, and a plurality of grinding wheel devices 700 corresponding to each clamp 620 are provided on the other side of the upper part of the base 100.

[0020] The gear bar 400 has multiple sliders 410 fixed to its rear end. Two guide rods 420 slide inside the sliders 410, and fixing blocks 430 are located on either side of the upper end of the slide 200 to secure the ends of the guide rods 420. The coordination of the sliders 410, the two guide rods 420, and the fixing blocks 430 allows the gear bar 400 to move smoothly and linearly. The slide 200 has sliders 210 at both ends of its bottom, and support rails 800 are located on either side of the upper end of the base 100, slidably mating with the sliders 210. The slide 200 and support rails 800 form a forward and backward sliding connection with the base 100. The coordination of the sliders 210 and support rails 800 allows the slide 200 to move smoothly and even allows the slide 200 and the tool to be suspended. The first and second reciprocating drive members 300 and 500 are electric push rods. Compared to hydraulic rods and cylinders, electric push rods do not require complex system support, offer precise stroke positioning, are low-cost, and are easy to maintain. The grinding wheel device 700 includes a C-shaped frame 710 fixed to the top of the base 100, a grinding wheel 720 vertically rotatably mounted inside the C-shaped frame 710, and a motor 730 for rotating the grinding wheel 720. Specifically, in this embodiment, when in use, the tool can be positioned and clamped in turn by each clamp 620 so that the cutting edge faces the grinding wheel 720, and then, according to the angle at which the cutting edge needs to be ground, the gear bar 400 is pushed left and right by the second reciprocating drive member 500 to fine-tune, thereby driving the half gear disk 600, the clamp 620 and the tool to rotate. After the adjustment is completed, the entire slide 200 is pushed forward by the first reciprocating drive member 300 until the cutting edge of the tool contacts the grinding wheel 720, and then the cutting edge of the tool is passivated and ground by the rapidly rotating grinding wheel 720, so that multiple tools can be passivated at the same time, with simple operation, high passivation efficiency, and more uniform passivation quality compared to manual operation.

[0021] Furthermore, the clamp 620 in this embodiment can be a pneumatic clamp, an electric clamp, a manual clamp, etc., depending on actual needs and is not limited to this.

[0022] Furthermore, a rotating shaft 630 is fixed at the axis of the half gear plate 600, and the rotating shaft 630 is rotatably mounted on the slide 200 through a bearing. It can be understood that the gear bar 400 has multiple sections of linear gears corresponding to the half gear plate 600, so that multiple half gear plates 600 can maintain a uniform angle and rotate synchronously. In addition, the rotating shaft 630 is installed through a bearing, so that the half gear plate 600 and the furniture 620 are smoother and more stable when rotated and adjusted.

[0023] In summary, a tool passivation device in this embodiment can be used to position and clamp the tool in sequence through each clamp 620 so that the cutting edge faces the grinding wheel 720. Then, according to the angle at which the cutting edge needs to be ground, the gear bar 400 is pushed left and right by the second reciprocating drive member 500 to fine-tune, thereby driving the half gear disk 600, the clamp 620 and the tool to rotate. After the adjustment is completed, the entire slide 200 is pushed forward by the first reciprocating drive member 300 until the edge of the tool contacts the grinding wheel 720. Then, the edge of the tool is passivated and ground by the rapidly rotating grinding wheel 720, so that multiple tools can be passivated at the same time. The operation is simple and the passivation efficiency is high.

[0024] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
