An air cylinder is arranged at the bottom of the moving mechanism. Through the design of the driving motor, the air cylinder, the moving mechanism and other assemblies, automatic lifting, moving and fixing of the containing barrel and workpiece drying are achieved, the process is simplified, the labor intensity is reduced, and the working efficiency is improved; through the design of the two driving mechanisms, the inner shell and the outer shell of the washing and dissolving device reciprocate to form vortex and turbulent flow, the washing and dissolving capacity of cleaning liquid is enhanced, and thorough and efficient cleaning is achieved; and through the design of the locking mechanism, the containing barrel and the special-shaped workpiece are effectively fixed, uneven cleaning or workpiece damage caused by shaking in the cleaning process is avoided, and the cleaning stability and safety are improved.

The utility model provides a universal electric drill gun, including drill gun body and rotation cover, is equipped with power axis on the drill gun body, is equipped with first steering body on power axis, is equipped with second steering body one side of first steering body, and one steering body and second steering body structure are same, is equipped with output shaft on second steering body, first steering body includes half tooth ball, and the half tooth ball of first steering body is engaged with the half tooth ball of second steering body. The overall structure can realize the angle adjustment of output shaft, and the output shaft after adjustment makes the drill bit align target position, avoids the phenomenon of drilling deviation, skidding, even damaging workpiece or electric drill gun itself due to the instability of unable to adjust stress. The overall device can be applied to non-vertical or non-horizontal inclined angle drilling requirements, has a larger application scene range, high operation efficiency, convenient operation and great popularization value.

The utility model belongs to numerical control processing technical field discloses a numerical control processing combined tool and numerical control processing equipment, including handle and tool bit subassembly, wherein tool bit subassembly installs in the working end of handle, tool bit subassembly includes tool bit body and sets up a plurality of processing cutting edges on tool bit body, and a plurality of processing cutting edges include edge correction blade, rough milling blade, up and down chamfer blade, fine milling blade and dovetail reverse chamfer blade from top to bottom along handle axial in proper order, this numerical control processing combined tool and numerical control processing equipment not only avoided the positioning error and workpiece damage caused by frequent replacement of tool, improved the stability and continuity of processing process, reduced artificial intervention, also effectively reduced the processing difficulty and manufacturing cost of subsequent rework, polishing and other procedures, effectively inhibited burr, corner and misplacement defects, improved processing precision and corner quality, especially suitable for high appearance precision requirement shell type part's large batch automation processing.

This utility model relates to the field of muffler processing technology, specifically to a muffler assembly welding fixture with a clamping and positioning structure. It includes a worktable, with two support plates fixedly connected to the top of the worktable. A fixed rotating mechanism is rotatably connected inside the support plates. The fixed rotating mechanism includes a second connecting column, a first fixing column fixedly connected to the outside of the second connecting column, a protective shell fixedly connected to the outside of the first fixing column, and a motor fixedly connected to the outside of the first fixing column. A gear is fixedly connected to the drive end of the motor. A transmission assembly is provided inside the protective shell, and a second gear is fixedly connected to the outside of the protective shell. This utility model achieves multi-station continuous welding by having the motor of the fixed rotating mechanism drive the gear set and the muffler to rotate, combined with the welding body sliding along a groove. This eliminates the need for frequent adjustments to the workpiece and welding torch positions, and strengthens the fixation of the muffler.

The utility model belongs to rubber product forming die technical field, concretely relates to a kind of preforming rubber mould, including rubber sleeve mould, and rubber sleeve mould includes male die and female die, is provided with several convex moulds on male die, and mould is same with workpiece specification, and several inner concave mould cavities matched with mould are formed on female die, and mould and mould cavity are one-to-one correspondence, corresponding positioning hole is provided on male die and female die, and the positioning of male die and female die is realized by positioning column assembly to positioning hole, after male die and female die are matched, mould is placed in mould cavity, and clearance layer is between the outer surface of mould and mould cavity inner wall, and clearance layer constitutes the forming cavity of rubber sleeve.
