Abstract
The utility model discloses a supercharging device for vacuum diffusion welding. The supercharging device for the vacuum diffusion welding comprises a base plate for placing a workpiece to be welded, a supercharging mechanism and a clamping mechanism, wherein the supercharging mechanism and the clamping mechanism are respectively arranged on two sides of the workpiece to be welded. The supercharging mechanism comprises a fixed trapezoid block arranged on the base plate and a wedge-shaped fixture block placed between the fixed trapezoid block and the workpiece to be welded, wherein weights are arranged on the upper surface of the wedge-shaped fixture block. Inclination angles of contact surfaces of the fixed trapezoid block and the wedge-shaped fixture block are identical. The upper surface of the wedge-shaped fixture block is provided with grooves. The clamping mechanism comprises a threaded sleeve arranged on a welding device frame and a movable lead screw matched with the threaded sleeve, wherein the end of the lead screw close to one end of the workpiece to be welded is fixedly connected with a blocking plate, and the other end of the lead screw is provided with a rocking handle. The supercharging device has the advantages of being simple and reasonable in structure, practical and convenient to operate. The supercharging device with an independent structure can achieve the effect of 'one furnace with dual purposes', and the production cost is saved.
Description
Technical field
The utility model relates to vacuum diffusion welding and connects equipment, especially relates to a kind of vacuum diffusion welding supercharging device.
Background technology
The diffusion welding (DW) of material is that one of the key property with " physics is pure " surface is a basis, and this kind surface is owing to the atomic bond with cracking has " combination " ability.After the method on employing vacuum and other purification surfaces, just might utilize above-mentioned atomic binding forces, connect two and plural surface, the surperficial subsequently diffusion process that goes up generation has improved the intensity of this connection.Adopt diffusion welding method, can connect have different hardness, intensity, wetting various materials each other, comprising dissimilar metal, pottery, cermet etc., the welding of these materials all can not reach good effect with melt welding method.Diffusion Welding requires to have an enough extruding force, so that make reduced distances between the face of weld to the interaction radius of power between the atom, connects the unevenness that the required pressure of a certain material should be enough to eliminate the surface of the work microcosmic.At present, the pressure mechanism that vacuum diffusion welding connects equipment mainly adopts supercharging air mechanism and hydraulic booster mechanism, and not only structure is very complicated, cost an arm and a leg, and the defective of ubiquity poor sealing.
Summary of the invention
The purpose of the utility model is to provide a kind of vacuum diffusion welding supercharging device simple in structure, and this device can cooperate vacuum brazing furnace to realize that the diffusion welding (DW) of soldering work piece connects.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The described vacuum diffusion welding supercharging device of the utility model; Comprise the base plate of placing workpiece to be welded and place the booster body and the clamp mechanism of workpiece to be welded both sides respectively; Described booster body is to be arranged on fixedly trapezoid block and movable on the said base plate to be placed on the fixedly wedge shape fixture block between the trapezoid block and workpiece to be welded, and the upper surface of said wedge shape fixture block is placed with counterweight.
Said fixedly trapezoid block is identical with the angle of inclination of wedge shape fixture block contact-making surface.
The upper surface of said wedge shape fixture block offers groove.
Said clamp mechanism is the movable leading screw that is horizontally set on the screw shell on the welding equipment support body and is complementary with screw shell, is fixed with baffle plate in the leading screw end near workpiece one end to be welded, is provided with rocking handle at the other end of leading screw.
The advantage of the utility model is simple and reasonable for structure, easy to operate practicality.The supercharging device of absolute construction can reach the effect of " stove is dual-purpose ", has practiced thrift production cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; The described vacuum diffusion welding supercharging device of the utility model; Comprise the base plate 1 of placing workpiece A to be welded and B and clamp mechanism and the booster body that places the workpiece A to be welded and the B left and right sides respectively; Its booster body is to be arranged on fixedly trapezoid block 2 and movable on the base plate 1 to be placed on the fixedly wedge shape fixture block 3 between the trapezoid block 2 and workpiece B to be welded; Upper surface at wedge shape fixture block 3 offers groove 5, is placed with counterweight 4 in the groove 5, and fixedly trapezoid block 2 is identical with the angle of inclination of wedge shape fixture block 3 contact-making surfaces; Used clamp mechanism is the movable leading screw 7 that is horizontally set on the screw shell 6 on the welding equipment support body and is complementary with screw shell 6, is fixed with baffle plate 8 in the leading screw end near workpiece A one end to be welded, is provided with rocking handle 9 at the other end of leading screw.
During use, workpiece A and the B of needs welding is placed on the base plate 1, wedge shape fixture block 3 is placed on fixedly between the trapezoid block 2 and workpiece B to be welded, maintenance wedge shape fixture block 3 does not contact with base plate 1; Shake rocking handle 9; Movable leading screw 7 is along screw shell 6 rotations; Drive baffle plate 8 and move to workpiece A, baffle plate 8 clamps workpiece A and B with wedge shape fixture block 3 together, in the groove 5 of wedge shape fixture block 3 upper surfaces, places the counterweight 4 of constant weight; Under the gravity effect, 4 pairs of wedge shape fixture blocks 3 of counterweight apply vertically downward a pressure.In the Diffusion Welding process, along with the fusing of solder, the joint gap diminishes, and under the gravity effect of counterweight 4, wedge shape fixture block 3 can move down along the fixing inclined-plane of trapezoid block 2, and to the pressure that workpiece B applies amplification, realizes that diffusion welding (DW) connects.
