Description

A telescopic adjustable hydraulic cylinder

technical field

The utility model relates to the technical field of mechanical equipment, in particular to a telescopic adjustable hydraulic cylinder.

Background technique

The hydraulic cylinder is the actuator in the hydraulic system, which can convert hydraulic energy into mechanical energy of reciprocating motion, and has important applications in engineering, transportation, machine tools, mining metallurgy and other fields. At present, the control of the telescopic stroke of the hydraulic cylinder is mainly realized by setting a travel switch on the extension path of the piston rod. In this working mode, it is difficult to adjust for the workplace where the piston telescopic stroke needs to be changed frequently.

Utility model content

The purpose of the utility model is to provide a telescopic adjustable hydraulic cylinder in order to remedy the defects of the prior art.

The utility model is achieved through the following technical solutions:

A telescopic adjustable hydraulic cylinder, including a hydraulic cylinder, characterized in that: a boss is provided on one side of the end cover of the hydraulic cylinder, a travel switch is fixed on the boss, and the piston rod of the hydraulic cylinder extends A scale support is covered with a scale support, and a scale is fixed on the scale support, and the scale is located on the same side as the travel switch. .

The telescopic adjustable hydraulic cylinder is characterized in that there are multiple positioning holes on the scale, and the distance between adjacent positioning holes is 10 mm.

The telescopic adjustable hydraulic cylinder is characterized in that: the positioning holes on both sides of the travel switch on the scale are respectively equipped with a contact.

The utility model has the advantages of:

The utility model fixes the travel switch on the cylinder body of the hydraulic cylinder, adds a scale and a scale bracket, and adopts the method of changing the installation position of the contact on the positioning hole of the scale to realize the adjustment of the telescopic stroke of the hydraulic cylinder, which can not only simplify the stroke control The adjustment operation improves the accuracy of the stroke adjustment of the piston rod, and can also optimize the structural layout of the equipment, which brings convenience to industrial production and can also reduce production costs.

Detailed ways

As shown in Figure 1 and Figure 2, the utility model is a telescopic adjustable hydraulic cylinder, which mainly includes a hydraulic cylinder body 1, an end cover 2, a piston rod 3, a scale bracket 4, a scale 5, a contact 6, and a travel switch 7 , contact 8. One side of the hydraulic cylinder block 1 is fixed with an end cover 2; the piston rod 3 is covered with a scale bracket 4; the scale bracket 4 is fixed with a scale 5; the scale 5 is in The two sides of the travel switch 7 are respectively equipped with contacts 6 and 8; the travel switch 7 is fixed on the boss on one side of the end cover 2; the scale 5 and the travel switch 7 are located on the same side of the hydraulic cylinder ; The contact 6 and the contact 8 move linearly with the piston rod 3 on the scale 5 .

The utility model is a telescopic adjustable hydraulic cylinder. The specific operation is: when the piston rod 3 extends to a predetermined length, the contact 6 drives the stroke switch 7 to act, and sends a signal to stop extending; when the piston rod 3 retracts, The contact 8 drives the stroke switch 7 to act, and sends out a stop signal; when it is necessary to adjust the stroke length of the extension and retraction of the piston rod 3, it is only necessary to adjust the positions of the mounting holes of the contact 6 and the contact 8.
