Detailed Implementation

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0030] Implementation

[0031] Please see Figure 1 -4. A multi-station deposition fixture for stainless steel coating on cutting tools, comprising:

[0032] Top plate 1 and bottom plate 2;

[0033] A slide bar 3 is fixedly installed between the top plate 1 and the bottom plate 2;

[0034] The first movable block 4 is slidably set outside the slide bar 3, and the second movable block 5 is slidably set outside the slide bar 3 and below the first movable block 4;

[0035] A clamping unit fixedly installed on one side of movable block 4 and movable block 5 is used to clamp the cutting tool;

[0036] A hydraulic drive unit fixedly installed inside the top plate 1;

[0037] The tool position adjustment unit is fixedly installed inside the first movable block 4 and the second movable block 5, and is used to adjust the position of the tool.

[0038] The tool position adjustment unit includes a first neodymium magnet 6 fixedly installed inside the first movable block 4, a fixed bearing 7 fixedly installed inside the second movable block 5, a rotating shaft 8 rotatably installed inside the second movable block 5 via the fixed bearing 7, a second neodymium magnet 9 fixedly installed inside the rotating shaft 8, a rotating handle 10 located on one side of the second movable block 5 and fixedly connected to the rotating shaft 8, and a support spring 11 fixedly installed at the bottom of the second movable block 5.

[0039] The technical solution provided in this embodiment is as follows: In use, the tool to be clamped is first placed between the two clamping heads 15. Then, the hydraulic rod 12 is activated to push the drive plate 13 downward, which in turn moves the first movable block 4 and the second movable block 5 closer together through the slide rod 3. This causes the two support rods 14 to move closer together, so that the two clamping heads 15 clamp the tool. When the tool is not in the correct position, the handle 10 can be rotated, which in turn rotates the rotating shaft 8 to drive the second neodymium magnet 9 to rotate, so that the positive pole of the second neodymium magnet 9 is aligned with the positive pole of the first neodymium magnet 6. Then, the repulsive force of the magnet compresses the support spring 11, separating the first movable block 4 and the second movable block 5, so that the two clamping heads 15 release the clamped tool, allowing the worker to change the position of the tool by hand.

[0040] Furthermore, the hydraulic drive unit includes a hydraulic rod 12 fixedly installed inside the top plate 1 and a drive plate 13 fixedly installed at the bottom end of the hydraulic rod 12, with the bottom surface of the drive plate 13 abutting against the top surface of the first movable block 4.

[0041] Specifically, by pressing the bottom surface of the drive plate 13 against the top surface of the first movable block 4, the movement of the first movable block 4 and the second movable block 5 can be restricted. When the hydraulic rod 12 is activated to push the drive plate 13 downward, the first movable block 4 and the second movable block 5 can be pressed tightly together, thereby allowing the clamping head 15 to clamp the tool.

[0042] Furthermore, the clamping unit includes two support rods 14 fixedly installed on one side of the first movable block 4 and the second movable block 5, and two clamping heads 15 fixedly installed on one end of the two support rods 14.

[0043] Specifically, by installing two support rods 14 on one side of the first movable block 4 and the second movable block 5 respectively, when the hydraulic rod 12 pushes the drive plate 13 to bring the first movable block 4 and the second movable block 5 closer, the two support rods 14 will move closer, thereby bringing the two clamping heads 15 closer and clamping the tool.

[0044] Furthermore, a central shaft 16 is fixedly installed on the top of the base plate 2, the central shaft 16 passes through the top plate 1, and a lifting handle 17 is fixedly installed on the top of the central shaft 16.

[0045] Specifically, by fixing the central shaft 16 to the top of the base plate 2 and passing through the top plate 1, the central shaft 16 can fix the top plate 1 and the base plate 2, and can share the pressure between the top plate 1 and the base plate 2 when the hydraulic rod 12 is activated. By fixing the lifting handle 17 to the top of the central shaft 16, the tool holder can be lifted by pulling the lifting handle 17 when needed.

[0046] Furthermore, when the handle 10 is not rotated, the positive pole of the first neodymium magnet 6 and the negative pole of the second neodymium magnet 9 are magnetically attracted to each other.

[0047] Specifically, by setting the handle 10 to magnetically attract the positive pole of neodymium magnet 6 and the negative pole of neodymium magnet 9 when the handle is not rotated, the handle 10 can be rotated to rotate neodymium magnet 9 via the rotating shaft 8 when the tool position needs to be adjusted. This causes the positive pole of neodymium magnet 9 to align with the positive pole of neodymium magnet 6, thereby compressing the support spring 11 and separating movable block 4 and movable block 5. This causes the clamping head 15 to release the tool and adjust its position.

[0048] Furthermore, there are multiple support springs 11, and the support springs 11 are connected to the top surface of the first movable block 4.

[0049] Specifically, by connecting the support spring 11 to the top surface of the first movable block 4, the support spring 11 can be fixed by the first movable block 4 when the second movable block 5 is pressed down, preventing the support spring 11 from shifting due to pressure.

[0050] Furthermore, there are multiple slide bars 3, and these slide bars 3 are arranged in a rectangular array inside the first movable block 4 and the second movable block 5.

[0051] Specifically, by arranging multiple slide bars 3 in a rectangular array inside the first movable block 4 and the second movable block 5, the first movable block 4 and the second movable block 5 can be restricted to moving only up and down, thereby ensuring that the two clamping heads 15 can accurately clamp the tool.

[0052] Furthermore, the clamping head 15 is made of reinforced plastic, and the two clamping heads 15 are in a planar position relative to each other.

[0053] Specifically, the clamping head 15, made of reinforced plastic, can reduce wear on the tool during clamping. By setting the relative positions of the two clamping heads 15 to be flat, the clamping heads 15 can clamp the tool more securely.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
