Description

Technical Field

[0001] The invention relates to a precise supporting and positioning device for vacuum welding of a corn spiral milling cutter and a use method thereof. Background Art

[0002] Corn spiral milling cutter, also known as corn cob milling cutter, also called scaly milling cutter, has a dense spiral mesh on the surface and a relatively shallow groove. It is generally used for processing some functional materials, especially some carbon fiber Kraft materials (such as the outer shell of an airplane wing) and glass fiber and other composite materials.

[0003] The cutting edge of the solid carbide scale milling cutter is composed of many cutting units. The cutting edge is sharp, which greatly reduces the cutting resistance and can achieve high-speed cutting, achieving the effect of milling instead of grinding, improving the processing efficiency and surface quality of composite materials, and extending the service life of the milling cutter.

[0004] When processing corn spiral milling cutters, vacuum welding is usually used for welding. During welding, the cutter head is installed in a preset position on the cutter seat and then sent to a vacuum welding machine for welding.

[0005] However, there are several disadvantages in welding: in order to achieve better cutting effect, there is usually a certain angle between the cutting edge and the tool holder, which needs to be installed and adjusted before welding, and its overall connectivity is poor. When the vacuum welding machine is turned off and vacuum is evacuated, slight vibrations will cause the cutting edge to deviate from the preset position, resulting in defective products due to position deviation. Therefore, there is an urgent need for a precise support and positioning device for vacuum welding of corn spiral milling cutters. Summary of the invention

[0006] The purpose of the present invention is to provide a precise support and positioning device for vacuum welding of a corn spiral milling cutter and a method of using the same, so as to solve the problems raised in the above-mentioned background technology.

[0008] The adjustment mechanism comprises a sector block, a bearing frame is arranged on the surface of the sector block, and a plurality of extrusion blocks capable of supporting the cutting edge are arranged on the bearing frame;

[0009] The surface of the support frame is provided with a placement seat which can stably support the entire device.

[0010] Preferably, a spherical block is arranged on the upper surface of the sector-shaped block, and a rotation groove for inserting the spherical block is arranged inside the sector-shaped block.

[0011] Preferably, a spring block is arranged on the surface of the extrusion block, and the spring block is arranged inside the bearing frame.

[0012] Preferably, a telescopic rod is provided at the lifting end of the surface of the bearing frame, and a supporting plate is provided on the surface of the telescopic rod.

[0013] Preferably, a suction plate is provided inside the placement seat.

[0014] Preferably, the surface of the support frame is provided with fixing blocks in a circular array, and the fixing blocks are provided with engaging grooves.

[0015] Preferably, a plug-in block which can be inserted into the engaging groove is arranged on the lower surface of the bracket, and elastic blocks are symmetrically arranged on the upper and lower surfaces of the plug-in block.

[0016] Preferably, a protruding block is provided on the lower surface of the plug-in block, and a limiting groove is provided inside the support frame at a position corresponding to the fixing block.

[0017] Preferably, the outer diameter of the spherical block is the same as the inner diameter of the rotating groove, and the outer surface of the spherical block and the inner surface of the rotating groove are both rough.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When the whole is in use, the plug-in block is inserted into the fixed block at different positions, so that the whole can support and position more types of corn spiral milling cutters, so that the whole is more flexible in use and has a wider range of applications;

[0020] 2. When supporting the cutting edge, the method of supporting and extruding is adopted to support it.

Under the action of the spring block, the extruded extrusion blocks are attached to the surface to support it, and the unextruded extrusion blocks limit the four sides of the cutting edge. In this way, the whole has a certain ability to resist external forces, which greatly reduces the occurrence of problems such as dislocation of the cutting edge during welding and affecting product quality. The whole can be widely applicable to the precise support and positioning device for vacuum welding of corn spiral milling cutters. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Furthermore, a telescopic rod 15 is provided on the lifting end of the surface of the carrier frame 13, and a supporting plate 16 is provided on the surface of the telescopic rod 15; by virtue of the telescopicity of the telescopic rod 15, the supporting plate 16 can accurately lift the bottom end of the cutting edge.

[0035] Furthermore, a suction plate 7 is provided inside the placement seat 6; when welding with a vacuum welding machine and air is extracted, the overall fixation is more firm and more stable under the action of the suction plate 7.

[0036] Furthermore, the surface of the support frame 1 is provided with fixing blocks 2 in a circumferential array, and the fixing blocks 2 are provided with engaging grooves 3; the plug-in block 4 and the bracket 9 are fixed by the engaging grooves 3 on the fixing blocks 2.

[0037] Furthermore, the lower surface of the bracket 9 is provided with a plug-in block 4 which can be inserted into the engaging groove 3, and the upper and lower surfaces of the plug-in block 4 are symmetrically provided with elastic blocks 8; the elasticity of the elastic block 8 is utilized to insert the notch in the engaging groove 3 to increase the fixing ability.

[0038] Furthermore, a protruding block 5 is provided on the lower surface of the plug-in block 4, and a limiting groove 17 is provided inside the support frame 1 at a position corresponding to the fixed block 2; by inserting the protruding block 5 into the limiting groove 17, the lower end of the bracket 9 is limited, so that the positioning of the bracket 9 is more accurate through the two-point limiting method, thereby increasing the overall support accuracy.

[0039] Furthermore, the outer diameter of the spherical block 12 is the same as the inner diameter of the rotating groove 11, and the outer surface of the spherical block 12 and the inner surface of the rotating groove 11 are both rough; thus, when the spherical block 12 rotates, it is easier to position under the action of high friction.
