Abstract
The utility model relates to a welding fixture, which is used for solving the technical problems of insufficiency and inconformity of clamping force during integral brazing. The welding fixture comprises an upper disc-shaped pressing plate and a lower disc-shaped pressing plate which are equal in diameter and are provided with coaxial central positioning holes, the lower pressing plate is provided with a toothed block positioning hole, and the lower surface of the lower pressing plate is provided with a toothed block mounting groove. The welding fixture is characterized in that a toothed block positioning screw and a toothed block compression spring are mounted between the upper pressing plate and the lower pressing plate. The welding fixture is simple in structure, and welding surfaces of a toothed block and a base can be constantly kept in tight connection by means of high-temperature welding, so that loosening and cold joint are avoided.
Description
Technical field
The utility model relates to a kind of weld jig, and specifically, the utility model relates to a kind of weld jig of high frequency brazing diamond disk.
Background technology
Diamond disk has been widely used in the various aspects in grinding field.Diamond disk is the effective tool of high crisp materials such as grinding stone material, carbide alloy, glass, pottery.Diamond disk is made up of diamond segment and matrix, in the manufacturing process diamond segment and matrix is prepared respectively, and then adopts the process of welding that diamond segment is fixed on the matrix.In the prior art, the method that generally adopts is diamond segment sintering in vacuum hotpressing equipment; The connecting technology of cutter head and matrix adopts high-frequency induction brazing.
In order to enhance productivity, we have developed integral solder technology, and operating efficiency can increase work efficiency 50% with respect to traditional soldering processes.But when adopting integral braze-welded technology, to having relatively high expectations of brazing jig.Anchor clamps of the prior art adopt manually fixing, pneumatic fixing and magnechuck fixed form.Though pneumatic fixed form has bigger improvement than manual fixed form, complex structure, the regulation of each joint piece all needs a special cylinder, and the clamping force of each joint piece is difficult to consistent, and the efficient that is installed is still very low.Overcome inefficient defective though magnechuck is fixed, because the joint piece is to be adsorbed on the card of disk by magnetic force, restraining force is very little; Along with the fusing of solder, weld seam shrinks, and between joint piece after the welding and the matrix warpage can take place; Produce distortion, influence the soldering adhesion strength.And adopt traditional manual weld jig, in integral braze-welded process, owing to receive the influence of high temperature, fixed screw gets loose easily; Cause when integral solder, clamping force of each joint piece is difficult to be consistent, and can not be close to and produces rosin joint thereby cause saving piece (tooth piece) easily.
The utility model content
When adopting integral braze-welded welding in order to solve, weld jig is fixing not tight to the tooth piece under the high temperature, the inconsistent defective of clamping force.The utility model people of the utility model has carried out creationary innovation to weld jig of the prior art, provides a kind of joint piece simple in structure, convenient to install and can guarantee the integral braze-welded special welding anchor clamps of the diamond disk of welding quality stable.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of weld jig; The disc top board and the disc lower platen that comprise equal diameters; Disc top board and disc lower platen have the center positioning hole of coaxial setting; Lower platen is provided with tooth piece locating hole, and the lower surface of lower platen is provided with tooth piece mounting groove, it is characterized in that being equipped with between top board and the lower platen tooth piece positioning screw and tooth piece holddown spring.
Preferably, said lower platen also is provided with the assist location hole, and described assist location hole evenly is provided with along donut, and preferably, the number in described assist location hole is 3.
Preferably, described tooth piece mounting groove evenly is provided with along concentric circles.Preferably, the lower surface of lower platen is provided with two toothrow piece mounting grooves.
Preferably, the number of described positioning screw equates with the tooth piece number of diamond disk.Preferably, the profile of described tooth piece mounting groove is identical with the shape of cross section of tooth piece.
The operation principle of the weld jig of the utility model is following: the weld jig of the utility model mainly is made up of elements such as disc top board, disc lower platen, tooth piece positioning screw and tooth piece holddown springs.In the time of welding; Workpiece (being the diamond disc matrix) is placed on the workbench of rotation, on workpiece matrix surface to be brazed, places silver solder and scaling powder, the tooth piece is set above that again; Lower platen with weld jig is placed on the tooth piece then; And making the tooth piece overlap with tooth piece locating slot, the center positioning hole that top board and lower platen are coaxial and the center-aligned of diamond disc matrix utilize the centralized positioning screw rod to make diamond disc be fixed on the workbench of rotation; Then the tooth piece positioning screw on the anchor clamps is arranged on each tooth piece, and the spring hitch that reverses on the holddown spring makes diamond disc matrix and tooth piece be fastenedly connected, put into then on the ratio-frequency welding frame that has rotating disk and weld.
The weld jig of the utility model is simple in structure, easy to use, and in high-temperature soldering, the spring expanded by heating can make to remain between the solder side of tooth piece and matrix to be fastenedly connected, and can not produce loosening, as rosin joint can not occur phenomenon.The weld jig of the utility model is specially adapted to integral braze-welded technology, when improving soldering efficient, can also guarantee enough adhesion strengths.
