The utility model discloses a double-station welding machine for automobile plastic parts, which comprises a welding table, a machine cover is arranged on the welding table, a translation mechanism capable of moving back and forth is arranged on the welding table, and a first station and a second station capable of synchronously moving in opposite directions are further arranged on the translation mechanism; the translation mechanism comprises a supporting table, the supporting table is arranged on the welding table, a longitudinal nut seat is further arranged at the bottom of the supporting table, the longitudinal nut seat is connected with a ball screw, the ball screw is rotationally arranged in an adjusting groove, and the adjusting groove is formed in the middle of the upper surface of the welding table; the supporting table is further provided with an opposite moving structure used for controlling the first station and the second station to move, workpieces can be conveniently and rapidly taken and placed, meanwhile, the workpieces can be rapidly clamped and loosened, and the workpiece taking and placing efficiency is improved; workpieces of different specifications can be clamped and fixed, meanwhile, stable welding extrusion force can be provided, and the welding efficiency is improved.

The building formwork self-locking connecting device comprises four inner clamping plates, four outer clamping plates, four inner clamping plate fixing blocks, four outer clamping plate fixing blocks and four spring bolts, every two of the four inner clamping plates form a group, the two groups of inner clamping plates are symmetrically arranged at the upper ends and the lower ends of the inner clamping plate fixing blocks, and the outer clamping plates are symmetrically arranged at the upper ends and the lower ends of the outer clamping plate fixing blocks. Every two of the four outer clamping plates form a group, the two groups of outer clamping plates are symmetrically arranged at the upper end and the lower end of the outer clamping plate fixing block, and one group of inner clamping plates and outer clamping plates which are oppositely arranged is locked through a spring bolt. The inner clamping plate and the outer clamping plate are rapidly attached through the spring bolt, and force needed by manually tightening a common nut to enable the inner clamping plate and the outer clamping plate to be clamped is reduced. The device is simple in structure, convenient to mount and dismount, and capable of fixing building templates of various models.

The utility model discloses a novel ring-bar combination quick locking bar and bar and bar needle clamp, and relates to the technical field of orthopedic medical instruments, the novel ring-bar combination quick locking bar and bar needle clamp comprises a plurality of bar needle clamps and a mounting rod, each bar needle clamp is formed by combining two connecting blocks, arc-shaped grooves are formed in the two ends of each connecting block, a through hole for the mounting rod to penetrate through is formed in each connecting block, and the mounting rod is arranged in each arc-shaped groove. The mounting rod comprises an upper mounting rod and a lower mounting rod, the lower mounting rod is detachably connected to the bottom of the upper mounting rod, the outer surface of the lower mounting rod is fixedly connected with a circular separation blade, the top of the upper mounting rod is fixedly connected with a fixing block, and the fixing block is rotatably connected with a cam; a plurality of bar needle clamps are installed on the bar needle clamps under the action of the protruding end of the arranged cam and the round blocking piece, the bar needles are clamped and fixed through the combination of the two arc-shaped grooves, the whole bar needle clamps can relatively rotate around the installation rod, multi-angle connection of the connecting rod and the metal bone needles is achieved, and different requirements are met.
