The power slide table is equipped with a low-speed high-torque hydraulic motor, the speed is adjustable, and the thread is accurately identified.
Easy to operate：
The 45° flip design simplifies the clamping process, and the vertical structure saves space;
The ratchet force booster mechanism reduces the artificial strength and is safe and reliable to operate.
Quality improvement：
Effectively reduce assembly damage, ensure the sealing and performance of hydraulic cylinders, and reduce the repair rate.
Product Introduction:
Vertical disassembly and disassembly machine is mainly used for disassembling and assembling various types of hydraulic support columns and jack hydraulic cylinders; Various types of hydraulic cylinders can also be disassembled and assembled by adding accessories. It is widely used in various types of hydraulic cylinders with double-extension and single-rod spiral connection of fully mechanized mining supports, and is also suitable for cylinder cylinders with clamp keys and guide sleeves. It solves the defect that the normal horizontal disassembly and assembly capacity of the large hydraulic cylinder is easy to buckle due to the action of self-gravity during dismantling and assembly, and the disassembly and assembly of each stage of the cylinder are carried out by standing up. It can also flexibly adjust the torque of the guide sleeve. The application of this equipment has greatly improved the efficiency of column cylinder assembly, greatly improved the quality of assembly, and reduced labor intensity. The main machine of the equipment adopts steel plate welding, which is made by metal processing after aging treatment, and adopts the clamping method of mechanical and hydraulic combination to make the column positioning and clamping reliable. In order to avoid the position, the hydraulic cylinder can be easily clamped by turning back 4 5 °, and the piston rod can be pressed in after standing. After clamping, a cylinder is placed at the bottom seat of the column that can be raised and lowered to adjust the effective distance between the screw mouth of the column and the rotating part; The guide rail at the upper end of the frame adopts a high-strength fuselage to withstand a large torque, and the lifting cylinder is used to make the power slide table rise and fall, and the power slide table and the frame are treated with wear-resistant materials. The dynamic part adopts a low-speed high-torque hydraulic motor and ratchet booster mechanism that is directly transmitted to the main shaft, and the speed range of the hydraulic motor can be adjusted for the recognition and tightening of the cylinder head nut. The oscillating vertical structure has the advantages of easy operation, easy introduction of spirals due to the influence of gravity, small floor area, and safety and reliability.
