This invention provides a welding fixture and welding equipment, including an inclined plate movably connected to a chassis and positioned above it. To achieve this movable connection, a connector is located at the center of the inclined plate's lower surface. A slot for embedding the connector is provided above the chassis, and inclined push rods are arranged in a circular array on the upper surface of the chassis. A slider is movably connected to the upper end of each inclined push rod, and a T-shaped groove for embedding the slider is provided on the lower surface of the inclined plate. A circular slide rail with a T-shaped cross-section is fixed to the upper surface of the inclined plate. A central shaft is located at the center of the inclined plate's upper surface, and two adjustable and rotatable adjustment frames are movably mounted above the inclined plate with the central shaft as the center. This invention, through the rotatable adjustment frames and the adjustable position of the clamping frames, enables the clamping of straight, corner, circular, and other complex shaped profiles.

The utility model discloses a kind of tension test equipment for metal pipe test, belong to material mechanics test technical field, including platform, the upper surface both sides of platform are symmetrically equipped with guide column, the inside of guide column is equipped with power equipment, and the output end of power equipment is fixedly installed with lifting beam, the upper surface of platform and the lower surface of lifting beam are symmetrically equipped with clamping body, the front surface of clamping body is equipped with trapezoidal groove, and trapezoidal groove is equipped with wedge plate and moves symmetrically in horizontal direction inside, the front end of wedge plate is located clamping body outside, clamping installation groove is equipped in the front end of the inner surface of wedge plate, the utility model is by being arranged on the extension wedge plate of clamping body outside with clamping structure, so that clamping point is located in front of equipment main body, so that the limitation to the overall length of metal pipe is broken through, without cutting, directly longer pipe material can be clamped and tensile test, significantly improve test efficiency, and it is convenient to evaluate the performance of pipe material different position.

The chuck body high-precision laser heat treatment device comprises a heat treatment box body, a linear rail and two lasers, an opening in the top end of the heat treatment box body and the linear rail are installed in a sealed mode, a pneumatic sliding block is installed at a rail groove in the bottom end of the linear rail, and a connecting rod fixing base is arranged at the bottom end of the pneumatic sliding block. A clamping jaw connecting rod is arranged at the bottom end of the connecting rod fixing base, a cross-shaped clamping jaw is arranged at the bottom end of the clamping jaw connecting rod, movable clamping blocks are installed at the four ends of the cross-shaped clamping jaw correspondingly, an air inlet valve is installed on the side wall of the clamping jaw connecting rod, and air channels are arranged in the clamping jaw connecting rod and the cross-shaped clamping jaw correspondingly. The air inlet valve is communicated with the four movable clamping blocks through air paths; according to the chuck body blackening device, coating soaking can be conducted in the feeding process, the blackening process of the chuck body is achieved, the problem that in the prior art, the coating is damaged when the chuck body is clamped can be solved, spraying is not needed in advance, and the laser heat treatment efficiency is greatly improved.

The invention relates to the technical field of heavy trundle support machining, and provides an automatic welding machine for heavy trundle support machining, which comprises a welding platform and an automatic welding machine, a mounting block is mounted at the top end of the welding platform, a moving assembly is mounted in the mounting block, a placing table is mounted at the top end of the mounting block, positioning blocks are mounted at the two ends of the top of the placing table, and clamping structures are arranged on the two sides of the placing table. By arranging the clamping structure, when the heavy trundle support is welded, through extrusion of an extrusion plate and one side of an extrusion seat, a connecting plate and a connecting block can be driven to move towards one side at the same time, so that the connecting block can move horizontally in the translation process, and the welding efficiency is improved. The pre-clamping block assembled at one end of the connecting block preferentially makes contact with and abuts against the two sides of the second workpiece of the component, contraction deformation is generated through the telescopic spring, then the pre-clamping procedure is completed, accurate positioning is achieved, deviation of subsequent clamping is avoided, and therefore pre-clamping work is completed.

The utility model discloses a kind of auxiliary positioning platforms for roll bearing chock assembly, including base, the inner side of base is provided with clamping positioning assembly, clamping positioning assembly includes first motor, the output end outer surface of first motor is fixedly installed with positive and negative screw rod one, the outer surface of positive and negative screw rod one is symmetrically connected with H type connecting block, the inner side surface of H type connecting block is symmetrically connected with first connecting rod, one end of first connecting rod is rotatably connected with U block one, the outer surface of one side of U block one is fixedly installed with portal frame, the outer surface of one side of portal frame is pasted with first flexible limiting pad, by the above structure, by starting first motor, first flexible limiting pad is clamped in the side of roll, reduce the stress of bottom second flexible limiting pad in bearing seat installation process, to some extent, the consumption of second flexible limiting pad and first flexible limiting pad is reduced, the service life of auxiliary positioning platform is greatly improved.
