The utility model discloses a mining front axle wing plate forming die installation workbench which is characterized by comprising an upper base plate, a lower base plate, a die lifting device, a die clamping device, a limiting block and a hydraulic control system. The upper base plate and the lower base plate control the installation height of the die, the die lifting device and the limiting block installed on the lower base plate can achieve stable and rapid movement of the die, and the die clamping devices installed on the upper base plate and the lower base plate can achieve rapid clamping and loosening of the die. The whole set of workbench can adjust the installation height of the die, is adaptive to press machines and dies of different models, has a rapid die replacement function, remarkably shortens the installation time of the die, eliminates errors possibly caused by manual tightening, and greatly improves the die replacement efficiency.

This utility model discloses a production fixture for turning diesel engine cylinder heads, including a worktable with legs installed at the bottom and a baffle fixed at the top. A guide mechanism is provided at the top of the worktable, and an L-shaped plate is fixed to the top of the guide mechanism. A pressing mechanism is provided on one side of the worktable. A guide groove is formed at the top of the worktable, and guide rails are installed on both sides of the inner wall of the guide groove. A slider one is slidably connected to the inner wall of the guide rails and is fixedly connected to a connecting block. A sliding groove is formed at the bottom of the guide groove, and a slider two is fixed to the bottom of slider one. This utility model provides guidance for the L-shaped plate during its movement through the guide mechanism. Simultaneously, the pressing mechanism drives the L-shaped plate to move, preventing it from retracting due to the reaction force of the cylinder head. Furthermore, the guide mechanism ensures that the clamping force generated by the pressing mechanism when holding the cylinder head is consistent, preventing cylinder head deformation due to uneven force.

The utility model discloses an end polishing mechanism of a gear motor shell, which comprises a portal frame, a roller type polisher arranged at the top of the portal frame, a double-shaft moving unit arranged at the top end of the portal frame and used for controlling the X-axis position and the Z-axis position of the roller type polisher, and a bottom table fixed at the center position of the bottom of the portal frame, a double-station pneumatic clamping assembly used for clamping two gear motor shells is installed at the top end of the bottom table. According to the flange end face gear motor shell polishing device, the portal frame, the double-shaft moving unit, the roller type polisher, the double-station pneumatic clamping assembly and other structures which are matched with one another are arranged, the double-station pneumatic clamping assembly is designed to fix two flange end face gear motor shells to be polished at the same time, and the X-axis position and the Z-axis position of the roller type polisher are controlled in combination with the double-shaft moving unit; continuous grinding machining operation of two workpieces is achieved, an operator only needs to conduct discharging and clamping after one period is finished, and frequent shutdown and starting are reduced.

The utility model is applicable to the technical field of condenser processing, and provides a double-tube expanding device for condenser processing, which comprises a base plate, and a mounting box is fixed at the top of the base plate; the assembling frames are symmetrically arranged in the mounting box, the distance between the assembling frames is adjustable, and rotating rods are rotationally mounted on the two assembling frames; the pipe expanding head is fixedly arranged on the rotating rod through a coupling and is used for expanding a pipe; the mounting frame is fixedly mounted on the assembling frame, a single-shaft motor is fixedly mounted on the mounting frame, and an output shaft of the single-shaft motor is fixedly connected with the rotating rod through a coupler. According to the double-pipe expanding device for condenser machining, the problem that the pipe expanding machining efficiency of an existing condenser is low is solved.

The utility model relates to a kind of part turnover structure of welding tool, including turnover frame installed on welding tool, the fixed assembly for fixing tubular part is provided on the turnover frame, the drive assembly for driving tubular part and fixed assembly turnover is provided on the turnover frame.This part turnover structure of welding tool, over setting positioning component, control component and mounting part, so that positioning rod is driven to expand by spring elastic force, cooperate with rubber sleeve and the flexible contact of tubular part inner wall, both can be through the uniform distribution of multiple point clamping of circumference Ensure that tubular part is not loose, can also avoid the extrusion deformation of rigid clamping to thin-walled or precision cylinder, surface scratch, and the elastic compensation effect of spring can be adapted to the small size deviation of workpiece, ensure that different position clamping force is consistent, and electric push rod controls positioning rod to be quickly folded, further shorten the installation process of tubular part, and certain diameter interval's tubular part can be adapted.
