Abstract
The utility model is a kind of speed governing cylinder, comprise: cylinder body, piston rod, front cover, rear end cover, described front cover and rear end cover are fixedly installed on the two ends of described cylinder body respectively, it is characterized in that, first series flow control valve is installed below described front cover, the second series flow control valve is installed in the below of described rear end cover, what described first series flow control valve regulated described piston rod returns speed, described second series flow control valve regulates the forward velocity of described piston rod, described first series flow control valve and the second series flow control valve are in series by Fixed differential reducing valve and throttle valve, the utility model is installed two series flow control valves and is replaced throttle valve on cylinder, can simultaneously regulating piston bar advance with return speed, movement velocity is stablized, realize the accurate quantification greasing between axle sleeve, improve the working life of manufacturing efficiency and cylinder.
Description
Technical field
The utility model relates to the cylinder technical field for bearing quantitative greasing, particularly relates to a kind of speed governing cylinder.
Background technique
Quantitative grease filling machine is the equipment that bearing industry is conventional, for injecting the lubricating grease (oil-impregnated bearing) of specified amount in bearing products.Because the number of lubricating grease injection amount, be directly connected to the lubrication state and temperature rise etc. of bearing in operation process, having the quality of bearing and life-span obviously affects, so in the manufacture of oil-impregnated bearing, the validity of greasing amount all has higher requirements.
Gas system is widely used in automatically producing with the advantage of its uniqueness, and cylinder is the primary component of pneumatic actuator system, and compressed air pressure can be converted into mechanical energy by it, realizes straight reciprocating motion.Cylinder, as modal actuator, has structure simple, and speed is fast, controls the advantages such as convenient, is thus widely used in the occasions such as clamping, loading and unloading conveying, bearing grease injection.But not The faster the better for the speed of cylinder, speed without control often causes cylinder to produce larger shock when stroke end, usually cutter can be interrupted, defective work piece and affect production, greatly have impact on the life-span of complete machine, in traditional quantitative grease-filling process, throttle valve is installed usually on cylinder to control flow, the motion speed of control cylinder, but throttle valve does not have flow reverse feedback function, the speed caused by load variations can not be compensated unstable, general only little or to the less demanding occasion of speed stability for load variations, for in accurate quantification greasing process, throttle valve does not realize this point.
Summary of the invention
The purpose of this utility model is intended to solve the deficiencies in the prior art, and provides a kind of motion speed to stablize, and can realize the cylinder of accurate quantification greasing.
The utility model for achieving the above object, by the following technical solutions: a kind of speed governing cylinder, comprise: cylinder body, piston rod, front cover, rear end cover, described front cover and rear end cover are fixedly installed on the two ends of described cylinder body respectively, it is characterized in that, install the first series flow control valve below described front cover, the second series flow control valve is installed in the below of described rear end cover, what described first series flow control valve regulated described piston rod returns speed, and described second series flow control valve regulates the forward velocity of described piston rod.
Described first series flow control valve and the second series flow control valve are in series by Fixed differential reducing valve and throttle valve.
The beneficial effects of the utility model are: the utility model is installed two series flow control valves and replaced throttle valve on cylinder, can simultaneously regulating piston bar advance with return speed, movement velocity is stablized, and realizes the accurate quantification greasing between axle sleeve, improves the working life of manufacturing efficiency and cylinder.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of speed governing cylinder of the utility model;
Fig. 2 is the left view of a kind of speed governing cylinder of the present utility model;
In figure: 1-cylinder body; 2-piston rod; 3-first series flow control valve; 4-second series flow control valve; 5-throttle valve; 6-Fixed differential reducing valve; 7-rear end cover; 8-front cover.
Be described in detail with reference to accompanying drawing below with reference to embodiment of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, a kind of speed governing cylinder, comprise: cylinder body 1, piston rod 2, front cover 8, rear end cover 7, piston, it is characterized in that, described front cover 8 and rear end cover 1 are separately positioned on the two ends of described cylinder body 1, install the first series flow control valve 3 below described front cover 8, and the second series flow control valve 4 is installed in the below of described rear end cover 7, what described first series flow control valve 3 regulated described piston rod 2 returns speed, and described second series flow control valve 4 regulates the forward velocity of described piston rod 2.
Described first series flow control valve 3 and the second series flow control valve 4 are in series by Fixed differential reducing valve 6 and throttle valve 5, described throttle valve 5 is connected with knob, by modified flow area, realize flow control, when knob turns clockwise, the restriction of throttle valve 5 strengthens gradually, and the flow passed through strengthens thereupon, in order to control flow.
