The utility model provides a kind of cannon head dismounting tool for blast furnace mud gun, including tight plate, it is blocking main body, for sticking cannon head end part to cannon head to exert resistance force, clamping plate is set to one side of tight plate, clamping plate is set to frame type structure, the inside wall of clamping plate is adapted to the connecting place of mud gun barrel and cannon head, for clamping positioning at the connecting place of mud gun barrel and cannon head, two connecting plates are respectively set to the two sides of tight plate and clamping plate, for connecting tight plate and clamping plate, to form the dismounting force structure to cannon head, the utility model is dismounted cannon head by mud pressure generated axial thrust steadily by tight plate and clamping plate cooperation, replace traditional hammering, avoid metal debris splashing, cannon head falling off and impact force cause equipment connecting place deformation, sealing element failure, improve dismounting safety and equipment reliability.

The utility model discloses a kind of fly knives of chipper for being convenient to install belong to chipper technical field, including handle, the side fixed connection of handle has first plug-in block, the normal surface of first plug-in block is equipped with hole slot, the inside plug-in of hole slot has connecting assembly;Connecting assembly includes plug-in rod, one end of plug-in rod is inserted in the inside of hole slot, the other end of plug-in rod is fixedly connected with second plug-in block, the normal surface of second plug-in block is fixedly connected with first spring, the side fixed connection of first spring has stress plate, the upper and lower two sides of second plug-in block are fixedly connected with driving frame;Through the connecting assembly of being set, first spring can push second plug-in block, i. e. it can push plug-in rod, by the push of multiple first springs, the stress balance of each place can be guaranteed, second plug-in block and first plug-in block can be connected by plug-in rod, guarantee the stability of connection, so that the blade installation position positioning is accurate, guarantee the stability of installation.

The utility model discloses a fall box mechanism, this mechanism includes frame body, lifting mechanism, first falling mechanism, the middle position of frame body forms the accommodation cavity for accommodating the stacked meal box, lifting mechanism sets up in the left and right sides of the accommodation cavity for the control of the edge of the upper layer meal box in the stacked meal box to the lifting state, first falling mechanism sets up in the left and right sides of the accommodation cavity and is located the below of lifting mechanism, for the control of the edge of the lower layer meal box in the stacked meal box to the lifting state.

This utility model belongs to the field of battery pack positioning technology, specifically relating to a quick-change precision positioning device for a PACK production line tooling trolley. It includes a trolley, a guide assembly, and a quick-change mechanism. A positioning pin is set at the bottom of the guide assembly, which inserts into a positioning hole on the trolley. The quick-change mechanism includes a thumb-shaped clamp and a cam sleeve. The lower end of the thumb-shaped clamp is inserted into the cam sleeve, and quick locking or unlocking is achieved by rotating a knob. The trolley tray has multiple pre-set cam sleeve mounting positions, each corresponding to a product model. The guide assembly integrates a coarse guide, support, and precision positioning mechanism for the PACK placement on the top of the mounting plate, with at least two thumb-shaped clamps symmetrically arranged at the bottom to ensure balanced locking force. This device, through the pre-positioning cooperation between the positioning pin and the positioning hole and the thumb-shaped clamp's quick-locking structure, avoids the cumbersome operation of traditional bolt disassembly, achieving second-level model changeover. The multiple mounting positions support rapid model changeover, improving production line flexibility and assembly efficiency.

The utility model discloses a drill, include: drill rod and blade, the front end of drill rod forms the blade position, and the blade is assembled in the blade position, first screw hole is arranged to the drill rod, second screw hole is arranged to the blade, and the screw rod passes through first screw hole and second screw hole, and the blade is locked in the blade position, first screw hole has first central axis, and second screw hole has second central axis, and first central axis and second central axis are staggered and do not overlap, the central axis of first screw hole is lower than the central axis of second screw hole, and the screw rod 300 is tightened in the process in hole section A, and the screw rod applies the pressure of blade downward, after the screw rod passes through first screw hole and second screw hole and is tightened, and the screw rod forms locking force and pressure to the blade, and locking force can be clamped in the blade position with the blade, and the pressure can be pressed down in the blade position with the blade, effectively prevent the blade upward and jump.
