Description

Technical Field

[0001] The utility model belongs to a tool coating device, in particular to an oblique insertion type tool coating fixture with a diameter of 3.5 mm. Background Art

[0002] Among the various 3.5mm diameter cutting tools produced, many of them must be coated before they can be used. The current method of loading cutting tools for vacuum ion plating is to vertically insert the 3.5mm diameter cutting tools into a cup with a height of 40mm and an inner diameter of 4mm. The cup is directly inserted into a cup holder with a diameter of 200mm. In this way, only one layer of cutting tools can be placed at the existing height. This method loads very little, reduces the utilization rate of the furnace, and increases production costs. Utility Model Content

[0003] The utility model aims to overcome the above technical deficiencies and provide a simple-structured, low-cost oblique-insertion 3.5 mm diameter tool coating fixture. Because the tools are obliquely inserted, the spacing between the tools is reduced, so the furnace loading of multi-layer tools can be increased at the existing height, greatly improving the furnace loading capacity of tools.

[0004] The utility model is implemented as follows: an oblique insertion type 3.5 mm diameter tool coating fixture, including a center rod, a sleeve, a tool holder and a tool holder seat, the center rod is fixed on the base, the sleeve is sleeved on the center rod, the cylindrical tool holder seat is placed on the sleeve, and a plurality of cylindrical tool holders are welded on the surface of the tool holder seat at an upward angle, and the inner diameter of the tool holder is greater than 3.5 mm so that the tool and the tool holder are clearance-matched.

[0005] Further, the upwardly inclined welding angle on the surface of the tool holder seat is 45-60 degrees.

[0006] Furthermore, the spacing between the tool holders is 5-15 mm.

[0007] Furthermore, the inner diameter of the tool holder is preferably 4 mm.

[0008] Compared with the prior art, the beneficial effects of the utility model are: the utility model has a simple structure, ingenious design, easy operation and high efficiency, and can greatly increase the loading capacity of 3.5 mm diameter tools during coating, thereby reducing costs and increasing coating benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] In order to more clearly illustrate the technical solution of the implementation mode of the utility model, the drawings required for use in the implementation mode will be briefly introduced below. It should be understood that the following drawings only show certain embodiments of the utility model and therefore should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without paying creative work.

[0010] Figure 1 This is a structural diagram of an oblique insertion 3.5 mm diameter tool coating fixture. DETAILED DESCRIPTION

[0011] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0012] like Figure 1 The invention discloses an oblique insertion type 3.5 mm diameter tool coating fixture, comprising a center rod 1, a sleeve 2, a tool holder 4 and a tool holder seat 3. The center rod 1 is fixed on a base 6, the sleeve 2 is sleeved on the center rod 1, and a cylindrical tool holder seat 3 is placed on the sleeve 2. A plurality of cylindrical tool holders 4 are welded upwardly on the surface of the tool holder seat 3. The inner diameter of the tool holder 4 is greater than 3.5 mm so that the tool and the tool holder are matched with each other. The inner diameter is preferably 4 mm. The inclination angle of the upwardly inclined welding on the surface of the tool holder seat 3 is 45-60 degrees, and the spacing between the tool holders 4 is 5-15 mm. When the loading amount is satisfied as much as possible, the uniformity and coating effect of the coating are guaranteed.

[0013] The 3.5mm diameter coating fixture is composed of a tool holder with an inner diameter of 4mm welded on the surface of a tool holder seat with a diameter of 100mm. The 3.5mm diameter tool is placed in the tool holder with an inner diameter of 4mm. Therefore, one fixture can insert many layers of tools at the existing height, greatly increasing the amount of tools that can be loaded into the furnace.

[0014] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
