Tapping machine for processing end part of hydraulic oil cylinder

Abstract

The invention relates to the technical field of hydraulic oil cylinder machining, and discloses a tapping machine for hydraulic oil cylinder end treatment, three sleeve holes are formed, positioning cylinders are movably sleeved with the sleeve holes, a transmission gear ring is movably sleeved with a transmission groove, and a driving gear in meshing transmission with the transmission gear ring is fixedly connected to the position, located at the bottom of a control motor, in a base. The upper half portion of the cylindrical groove is movably sleeved with a first transmission sleeve, a limiting hole is formed in the bottom of the first transmission sleeve, the first transmission sleeve is movably sleeved with the top of a second transmission sleeve, transmission connecting rods are movably installed on the first transmission sleeve and the second transmission sleeve in the movable groove in a vertically symmetrical mode, and a hinge device is movably connected between the two transmission connecting rods in the movable groove. Through the design of the positioning cylinder, the transmission sleeve, the hinge device and the like, the tapping machine is more convenient to use, meanwhile, the safety is high, and the service life is longer.

Description

technical field [0001] The invention relates to the technical field of hydraulic oil cylinder processing, in particular to a tapping machine used for processing the end of a hydraulic oil cylinder. Background technique [0002] Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. Because it uses high hydraulic pressure, it is also used in many important mechanical equipment. Therefore, the production of hydraulic cylinders needs to ensure quality. Among them After drilling the end of the hydraulic cylinder, it is necessary to tap the thread. Generally, a tapping machine is used. The working principle of the tapping machine is simple: that is, the tap is rotated by the motor drive, and then the tap is aligned with the positioned workpiece. The wire machine has been widely used, but it still has some shortcomings: [0003] 1. When using the tapping machine, it is necessary to position the hy...

AI Technical Summary

Problems solved by technology

[0003]1. When using the tapping machine, you need to position the hydraulic cylinder first, then start the tapping machine and use the gear box to move down to align with the hole on the end face of the cylinder Tapping is performed, but the end of the hydraulic cylinder is generally a circle of holes, so that it needs to be repositioned to tap a hole, but this is time-consuming and laborious. At the same time, the tapping position of the tapping machine is fixed, which also reduces the understand its practicality;

[0004]2. When using the tap to tap the thread, it will drive the entire gearbox assembly to move downward, so that the whole gearbox will be driven up and down continuously during use, resulting in Its fatigue friction affects the support strength of the machine body. On the other hand, tapping the thread in this way also needs to provide the force for its up and down movement, which is more wasteful in terms of energy consumption;

[0005]3. When tapping the thread, the tap rotates continuously and moves downward, and when drilling into the hydraulic cylinder, the torque on the tap increases with the depth The larger it is, the larger the torque will easily cause the tap to break during the drilling process. If the damage is mild, it needs to be replaced with a new one, and if it is severe, it will cause it to collapse and injure the staff. Generally speaking, it is not conducive to long-term and safe use.
