Description

Technical Field

[0001] The utility model relates to the technical field of arc ion plating arc starting needles, in particular to an arc ion plating arc starting needle adjusting device. Background Art

[0002] An arc ion plating striker is a device used to initiate and maintain the arc discharge during the arc ion plating process. Its primary function is to contact the target surface under the influence of electric and magnetic fields, creating a short circuit and inducing high temperatures. This vaporizes the target and generates plasma. This plasma is accelerated by the electric field and deposited on the substrate, forming the desired coating. The distance between the striker and the target surface should be appropriately adjusted based on the specific coating requirements and target material characteristics to achieve the optimal coating effect.

[0003] During the use of the arc ion plating arc starting needle, an adjustment device is required. The Chinese utility model patent with the announcement number CN207581912U discloses an arc ion plating arc starting needle adjustment device, which includes a main rod, an outer sleeve, a spring, an adjustment stud and an arc starting needle. One end of the main rod is provided with an internal threaded hole for installing the adjustment stud, and the adjustment stud is installed in the internal threaded hole. A stepped structure for installing the spring is provided on the main rod. The outer sleeve is slidably sleeved on the main rod, and the spring is installed on the stepped structure of the main rod inside the outer sleeve. The utility model provides the outer sleeve with elastic force for adjusting the end of the stud along the axial direction of the main rod through a spring; a through groove is opened on the hole wall of the internal threaded hole of the main rod, and the vertical section of the arc-starting needle is installed in the through groove. Under the action of the spring elastic force, the arc-starting needle is fixed between the outer sleeve and the adjusting stud; when the distance between the arc-starting needle and the target surface needs to be adjusted, the adjusting stud is rotated, and the adjusting stud pushes the arc-starting needle to slide along the length of the through groove, and the arc-starting needle drives the outer sleeve to compress the spring, thereby realizing continuous adjustment of the position of the arc-starting needle.

[0004] However, during the use of this utility model, although directly rotating the adjusting stud can drive the arc needle to move, the arc needle is relatively small in texture, and the adjustment length of the arc needle should be more delicate. The adjusting stud and the arc needle are not provided with a deceleration structure, which can easily lead to excessive adjustment of the arc needle and cannot meet production needs. Therefore, an arc ion plating arc needle adjustment device is proposed to solve the above problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides an arc ion plating arc needle adjustment device, which has the advantage of being able to accurately adjust the arc needle. It solves the problem that although directly rotating the adjusting stud can drive the arc needle to move, the arc needle is small in texture, and the adjustment length of the arc needle should be more delicate. However, the adjusting stud and the arc needle are not provided with a deceleration structure, which easily leads to excessive adjustment of the arc needle and cannot meet production needs.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: an arc ion plating arc-starting needle adjustment device, comprising a mounting box and a drive housing fixedly connected to one side of the mounting box, a target body being provided on a side of the bottom of the mounting box away from the drive housing, an arc-starting needle body being provided on the front of the mounting box, and a deceleration adjustment structure being provided inside the drive housing to drive the arc-starting needle body for adjustment;

[0008] Furthermore, one end of the return spring away from the adjusting rack is fixedly connected to the mounting box, and the top of the drive housing is rotatably connected to a rotating handle for rotating the worm.

[0009] Furthermore, the top and bottom of the adjustment rack are fixedly connected to limit blocks extending into the interior of the installation box, and the inner wall of the installation box is provided with limit grooves adapted to the limit blocks.

[0010] Furthermore, a mounting shell is provided on the front of the mounting box, a connecting block is fixedly connected between the mounting shell and the adjusting rack, and the arc-starting needle body passes through the mounting shell.

[0011] Furthermore, a first clamping block is provided on the front side of the interior of the mounting shell, a second clamping block is fixedly connected to the back side of the interior of the mounting shell, the front side of the first clamping block is rotatably connected to a threaded rod extending to the front side of the mounting shell, and the end of the threaded rod away from the first clamping block is fixedly connected to a rotating handle.

[0012] Furthermore, the opposite sides of the first clamping block and the second clamping block are both in contact with the arc-starting needle body, and the opposite sides of the first clamping block and the second clamping block are both fixedly connected with anti-slip pads.

[0013] Furthermore, the left and right sides of the first clamping block are fixedly connected to positioning blocks inside the mounting shell, and the inner wall of the mounting shell is provided with positioning grooves adapted to the positioning blocks.

[0014] Furthermore, a contact needle is fixedly connected to one end of the arc-starting needle body close to the target body, and an internal threaded blind hole is provided on a side of the mounting box away from the driving housing.

[0015] Compared with the prior art, the present invention provides an arc ion plating arc starting needle adjustment device, which has the following beneficial effects:

[0016] 1. The arc ion plating arc starting needle adjustment device drives the worm to rotate by turning the rotating handle, and then drives the transmission worm gear to rotate by setting the worm, so that the transmission worm gear drives the adjustment rack to move, and then drives the arc starting needle body to be adjusted left and right. Due to the provision of the worm and the transmission worm gear, the movement of the adjustment rack can be decelerated, and thus when the staff adjusts the arc starting needle body, it can be more accurate.

[0017] 2. The arc ion plating arc needle adjustment device drives the threaded rod to rotate by rotating the rotating handle, and then drives the first clamping block to move by the threaded rod. At the same time, by setting the second clamping block, the arc needle body can be clamped and fixed, which is convenient for disassembly and assembly of the arc needle body. It solves the problem that although directly rotating the adjusting stud can drive the arc needle to move, the arc needle is small in texture, and the adjustment length of the arc needle should be more delicate. The adjusting stud and the arc needle are not provided with a deceleration structure, which easily leads to excessive adjustment of the arc needle and cannot meet production needs.
