Description

Technical Field

[0001] This utility model relates to the field of tool passivation technology, and in particular to a surface passivation device for tool coating treatment. Background Technology

[0002] Tool coating is a surface modification technology that improves tool performance by coating the tool surface with one or more thin films. This technology can give cutting tools excellent overall mechanical properties, thereby significantly improving machining efficiency and tool life. Before coating, the tool surface usually needs to be passivated, typically using a tool passivation device.

[0003] Existing tool passivation devices typically have a rotating disc that is raised and lowered, while the abrasive hopper is fixed. However, this setup makes it inconvenient for operators to change the abrasive in the hopper, especially when it is necessary to frequently change different abrasives, which leads to a decrease in the passivation efficiency of the tool. In order to address this technical problem, this application proposes a surface passivation device for tools before coating treatment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a surface passivation device for cutting tools before coating treatment. By adjusting the height of the abrasive barrel, it can accommodate cutting tools of different lengths for passivation treatment, ensuring more precise contact between the abrasive and the cutting edge, thereby improving the passivation effect and accuracy. The easy movement of the abrasive barrel also speeds up abrasive replacement, improving work efficiency and allowing operators to quickly change to suitable abrasives according to processing needs, adapting to different cutting tool materials and passivation requirements.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An apparatus for surface passivation before coating treatment of cutting tools, comprising:

Multiple telescopic rods are fixedly connected to the base plate on the side adjacent to the mobile platform, and a lifting assembly is provided at the middle of the bottom end of the mobile platform.

[0009] Furthermore, the lifting assembly includes a plurality of spiral rods rotatably connected to the bottom end of the moving platform. The bottom end of each spiral rod is threadedly connected to a fixed post. The bottom end of the fixed post is fixedly connected to the top end of the base plate. The top end of the fixed post is rotatably connected to a helical gear one. The helical gear one is threadedly connected to the spiral rods. The rear end of the helical gear one is meshed with a helical gear two.

[0010] Furthermore, a mounting plate is fixedly connected to the top outer wall of the fixed column, and multiple limiting blocks are fixedly connected to the rear side of the top of the mounting plate. Rotating rods are rotatably connected to the adjacent sides of the limiting blocks at both ends, and the outer walls of both ends of the rotating rods are fixedly connected to helical gears.

[0011] Furthermore, a motor is installed on the front side of the top of the mounting plate, and a driving bevel gear is fixedly connected to the driving end of the motor. A driven bevel gear is meshed with the rear side of the driving bevel gear, and the driven bevel gear is fixedly connected to the outer wall of the middle end of the rotating rod.

[0012] Furthermore, a connecting plate is fixedly connected to the adjacent side of the telescopic rods on both the left and right sides.

[0013] Furthermore, the front end of the housing is rotatably connected to multiple rotating doors.

[0014] Furthermore, casters are fixedly connected to the four corners of the bottom of the base plate.

A primary rotating disk 4 is rotatably connected to the inner wall of the top of the housing 1. Multiple secondary rotating disks 3 are provided at the bottom of the primary rotating disk 4. By rotating the primary rotating disk 4, the multiple secondary rotating disks 3 at its bottom can be rotated. Multiple tool fixing blocks 5 are provided at the bottom of the secondary rotating disks 3 to fix the tools. By fixing the tool to be blunted on the tool fixing block 5, the tool fixing block 5 can be rotated by rotating the secondary rotating disk 3, so that the tool rotates in the abrasive in the abrasive barrel 6.

[0027] Reference Figure 2-4The system includes a movable platform 7, with an abrasive container 6 fixedly connected to its top. A base plate 11 is located at the bottom of the movable platform 7, with casters 10 fixedly connected to each of the four corners of the base plate 11. The multiple casters 10 facilitate the movement of the abrasive container 6, allowing operators to easily replace the abrasive within it, thus improving the efficiency of abrasive replacement. Multiple telescopic rods 8 are fixedly connected to the base plate 11 on the side adjacent to the movable platform 7, improving the stability of the movable platform 7 during lifting. Connecting plates 9 are fixedly connected to the sides adjacent to the left and right telescopic rods 8. Multiple spiral rods 13 are rotatably connected to the center of the bottom of the movable platform 7. A fixing post 12 is threadedly connected to the bottom of each spiral rod 13, and the bottom of the fixing post 12 is fixedly connected to the top of the base plate 11. A helical gear 18 is rotatably connected to the top of the fixing post 12, and the helical gear 18 is threadedly connected to the spiral rod 13. Rotating the helical gear 18 allows the spiral rod 13 to move. 3. Rotation achieves the lifting effect of the moving platform 7. The rear end of the helical gear 18 is meshed with the helical gear 2 19. Rotating the helical gear 2 19 can rotate the helical gear 18. The top outer wall of the fixed column 12 is fixedly connected to the mounting plate 14. The rear side of the top of the mounting plate 14 is fixedly connected to multiple limit blocks. The adjacent side of the limit blocks at the left and right ends is rotatably connected to the rotating rod 20. The outer walls of both ends of the rotating rod 20 are fixedly connected to the helical gear 2 19. Rotating the rotating rod 20 can rotate the helical gear 2 19 at both ends. The front side of the top of the mounting plate 14 is equipped with a motor 15. The drive end of the motor 15 is fixedly connected to the active bevel gear 16. The motor 15 can drive the active bevel gear 16 to rotate. The rear side of the active bevel gear 16 is meshed with the driven bevel gear 17.

The driven bevel gear 17 can rotate the rotating rod 20.

[0028] Working principle: First, open the two rotating doors 2 and fix the tool to be blunted on the tool fixing block 5. Then, push the moving table 7 into the tool housing 1 and close the two rotating doors 2. The motor 15 drives the active bevel gear 16 to rotate. The active bevel gear 16 drives the driven bevel gear 17 to rotate. The driven bevel gear 17 drives the rotating rod 20 to rotate. The rotating rod 20 drives the two helical gears 19 at both ends to rotate. The two helical gears 19 then drive the helical gear 18 to rotate. The rotation of the helical gear 18 causes the spiral rod 13 to rotate, thereby lifting the moving table 7 and immersing the tool to be blunted into the abrasive in the abrasive barrel 6. Then, start the machine to make the first-stage rotating plate 4 rotate. The first-stage rotating plate 4 drives multiple second-stage rotating plates 3 to rotate, thereby blunting the tool with the abrasive in the abrasive barrel 6.
