Adjustable fixture for PVD coating

Abstract

This utility model discloses an adjustable fixture for PVD coating, including a base plate, an auxiliary component on the top of the base plate, and a clamping component on the inner side of the clamping component. The auxiliary component includes two movable plates, and a clamping plate is fixedly installed on the inner end of the slider. A material sheet is inserted between the upper and lower clamping plates. This adjustable fixture for PVD coating clamps the right clamping plate on the already sandblasted area by rotating the right knob, then releases the left clamping plate and moves the left clamping plate to the left via the left movable plate. This covers the already sandblasted area and exposes the unsanded area. The sandblasting steps are repeated to completely sandblast both sides of the left side, thus achieving complete sandblasting of the entire material sheet. The clamping plate prevents repeated sandblasting of the already sandblasted areas, thereby solving the problem of incomplete sandblasting caused by the clamping part being blocked by the fixture.

Description

Technical Field

[0001] This utility model relates to the field of PVD coating technology, specifically an adjustable fixture for PVD coating. Background Technology

[0002] PVD is an abbreviation for Physical Vapor Deposition, which refers to the deposition of the evaporated material and its reaction products onto a workpiece under vacuum conditions using a low-voltage, high-current arc discharge technique. PVD technology evaporates the target material and ionizes both the evaporated material and the gas. The electric field then accelerates the deposition of the evaporated material and its reaction products onto the workpiece. PVD films have advantages such as high hardness, low coefficient of friction, excellent wear resistance, and chemical stability. Currently, PVD coating technology is widely used in the coating treatment of carbide end mills, profiled tools, and welded tools.

[0003] Patent application number CN202323240689.9 describes "an adjustable clamp for PVD coating, comprising a base and a base plate, the base being fixedly connected to the base plate, a first side plate being fixedly connected to the outside of the base plate, a second side plate being fixedly connected to the side of the base plate away from the first side plate, a driving assembly being provided on the outside of the first side plate, a clamping assembly being provided on the side of the first side plate away from the driving assembly, a cleaning assembly being provided above the base plate, and the clamping assembly being provided. Through the cooperation of a bidirectional lead screw and a handle, the two clamping plates are brought closer together by a moving block, thereby clamping the object. The driving assembly can drive the clamp to rotate, thereby driving the clamped object to rotate in all directions, which is beneficial to improving the PVD sandblasting efficiency; the cleaning assembly can clean the clamped object in advance, which can effectively avoid dust on the clamped object and help ensure the PVD sandblasting effect."

[0004] In the aforementioned patent, although rotating the material ensures that both sides of the material can be effectively sandblasted, the clamping part is blocked by the clamp when the material is clamped, which prevents the clamped part of the material from being effectively sandblasted, resulting in incomplete sandblasting.

[0005] To address these issues, this invention provides an adjustable fixture for PVD coating. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides an adjustable fixture for PVD coating, which solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable fixture for PVD coating, comprising a base plate, an auxiliary component on the top of the base plate, a clamping component on the inner side of the auxiliary component, the auxiliary component comprising two movable plates slidably connected to the top of the base plate, a rotating disk rotatably connected to the inner side of each movable plate, the clamping component comprising two support plates, the support plates being fixedly installed on the inner side of the rotating disk, a sliding groove being provided inside the support plate, a slider being slidably connected inside the sliding groove, a clamping plate being fixedly installed on the inner end of the slider, and a material sheet being inserted between the upper and lower clamping plates.

[0008] Preferably, the slide groove is rotatably connected to a first screw, the threads on both sides of the center of the first screw have different directions of rotation, and the two sliders are respectively screwed to the outer sides of the threads of the first screw with different directions of rotation.

[0013] This invention provides an adjustable fixture for PVD coating. Compared with the prior art, it has the following advantages:

[0014] (1) The PVD coating uses an adjustable clamp to simultaneously approach and clamp the upper and lower sides of the material sheet through the clamping plate, thereby completing the clamping and fixing of the material sheet. After one side is sandblasted, the second motor is started to drive the rotating disk to rotate, which in turn drives the support plate to rotate, thereby driving the clamping plate to rotate and flipping the material sheet. After flipping, the other side of the material sheet is sandblasted by the PVD sandblasting assembly to ensure the integrity of the sandblasting.

[0015] (2) The PVD coating uses an adjustable clamp. By rotating the right knob, the right clamp is clamped on the part that has been sandblasted. Then, the left clamp is released and the left clamp is moved to the left by the left movable plate. This covers the part that has been sandblasted and exposes the part that has not been sandblasted. The previous sandblasting steps are repeated to completely sandblast both sides of the left side, thereby achieving complete sandblasting of the entire material sheet. The clamp prevents the sandblasted parts from being sandblasted repeatedly, thus solving the problem of incomplete sandblasting caused by the clamp being blocked by the clamp.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Please see Figures 1-4An adjustable clamp for PVD coating includes a base plate 1, an auxiliary component 3 on the top of the base plate 1, and a clamping component 2 on the inner side of the auxiliary component 3. The auxiliary component 3 includes two movable plates 31, which are slidably connected to the top of the base plate 1. A rotating disk 36 is rotatably connected to the inner side of each movable plate 31. The clamping component 2 includes two support plates 22, which are fixedly installed on the inner side of the rotating disk 36. A groove 23 is opened inside the support plate 22, and a slider 25 is slidably connected inside the groove 23. A clamping plate 21 is fixedly installed on the inner end of the slider 25, and a material sheet 4 is inserted between the upper and lower clamping plates 21.

[0023] A first screw 24 is rotatably connected inside the slide groove 23. The threads on both sides of the center of the first screw 24 have different directions of rotation. Two sliders 25 are respectively screwed onto the outer sides of the threads with different directions of rotation of the first screw 24. A rotating rod 26 is rotatably connected to the top of the support plate 22. A knob 27 is fixedly installed on the top of the rotating rod 26. The output end of the rotating rod 26 moves through the interior of the support plate 22 and is fixedly connected to the first screw 24. A second motor 35 is fixedly installed on the outer side of the moving plate 31. The output end of the second motor 35 moves through the interior of the corresponding moving plate 31 and is fixedly connected to the corresponding rotating disk 36.

[0024] In this embodiment, when performing PVD sandblasting on the material sheet 4, the material sheet 4 is placed between two corresponding upper and lower clamping plates 21, with the inner edge of the clamping plates 21 aligned with the center of the material sheet 4. The rotating knob 27 drives the rotating rod 26 to rotate, which in turn drives the first screw 24 to rotate. The rotation of the first screw 24 enables the two sliders 25 inside the slide groove 23 to move synchronously in opposite directions, thereby driving the clamping plates 21 on both sides to move closer and clamp the material sheet 4, thus completing the clamping and fixing of the material sheet 4. The PVD sandblasting assembly set above then sandblasts the material sheet 4. After one side is sandblasted, the second motor 35 is started to drive the rotating disk 36 to rotate, which in turn drives the support plate 22 to rotate, thereby driving the clamping plates 21 to rotate and flipping the material sheet 4. After flipping, the other side of the material sheet 4 is sandblasted by the PVD sandblasting assembly to ensure the integrity of the sandblasting. Example

[0025] Please see Figures 1-4 This embodiment provides a technical solution based on embodiment one: a side plate 32 is fixedly installed on the top of the base plate 1, and a second screw 33 is rotatably connected between the two side plates 32, and the second screw 33 is screwed through the interior of the corresponding movable plate 31.

[0026] A first motor 34 is fixedly installed on the outer end of the side plate 32. The output end of the first motor 34 moves through the interior of the corresponding side plate 32 and is fixedly connected to the second screw 33.

[0027] In this embodiment, when sandblasting the material sheet 4, due to the obstruction of the clamping plate 21, the sandblasting range of the material sheet 4 is only half of the material sheet 4 in a single sandblasting operation. After the upper and lower sides of the right side of the material sheet 4 are sandblasted, the first motor 34 on the lower right side is started to drive the second screw 33 to rotate. The rotation of the second screw 33 can drive the right moving plate 31 to move to the left, and move the two clamping plates 21 on the right side to the parts that have been sandblasted. Then, the right clamping plate 21 is clamped to the parts that have been sandblasted by rotating the right knob 27. Then, the left clamping plate 21 is released and moved to the left by the left moving plate 31, thereby covering the parts that have been sandblasted and exposing the parts that have not been sandblasted. The previous sandblasting steps are repeated to completely sandblast the two sides on the left side, thereby achieving complete sandblasting of the entire material sheet 4. The obstruction of the clamping plate 21 ensures that the sandblasted parts are not sandblasted repeatedly, thus solving the problem of incomplete sandblasting caused by the clamping parts being blocked by the clamp.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Working principle: During operation, when performing PVD sandblasting on material sheet 4, material sheet 4 is first placed between two corresponding upper and lower clamping plates 21, so that the inner edge of the clamping plate 21 is aligned with the center of material sheet 4; rotate the knob 27, the knob 27 drives the rotating rod 26 to rotate, the rotating rod 26 drives the first screw 24 to rotate in the slide groove 23. Since the threads on both sides of the center of the first screw 24 have different directions of rotation, the two sliders 25 move synchronously in opposite directions in the slide groove 23, causing the upper and lower clamping plates 21 to move closer and clamp the material sheet 4 synchronously.

[0030] After one side of the material sheet 4 is sandblasted, the second motor 35 is started. The output end of the second motor 35 passes through the moving plate 31 and drives the rotating disk 36 to rotate. The rotating disk 36 drives the inner support plate 22, the slide groove 23, the slider 25 and the clamping plate 21 to rotate together, so that the material sheet 4 is flipped over and the other side is sandblasted.

[0031] If a portion of the material sheet 4 is not sandblasted due to obstruction by the clamping plate 21, the first motor 34 can be started. The output end of the first motor 34 passes through the side plate 32 and drives the second screw 33 to rotate. The second screw 33 drives the screwed moving plate 31 to slide on the top of the base plate 1, moving the clamping plate 21 to the sandblasted area. The clamping plate 21 is then adjusted by the knob 27 to clamp the sandblasted area. The other clamping plate 21 is then moved to expose the unsandblasted area. The sandblasting steps are repeated to complete the full sandblasting of the material sheet 4.
