Abstract
The utility model discloses a pressure control device of a lathe hydraulic chuck, which relates to a control device for lathe components. The utility model solves the problem that a lathe only finishes the operation of rough machining or finish machining to the same work piece and reduces the service efficiency of the lathe and the machining efficiency of the work piece because the prior pressure control device of the lathe hydraulic chuck only provides single-stage pressure control to cause that a hydraulic chuck can only produce single clamp force to the work piece. The utility model comprises a hydraulic cylinder, a connecting pipeline and a reversal valve, wherein, the reversal valve is connected with a pressure conversion control circuit. The utility model is mainly used for lathes which use hydraulic chucks.
Description
Affiliated technical field
The utility model relates to a kind of control device of turned part, particularly relates to a kind of pressure control device of oild chuck.
Background technology
The pressure control device of present employed lathe oild chuck mainly is made of hydraulic cylinder, reversal valve and corresponding connecting line.Because this pressure control device only provides single stage of pressure control, therefore makes oild chuck can only produce single chucking power to workpiece.Because the chucking power to oild chuck when a lot of workpiece carry out roughing with fine finishining requires different, so on the lathe that uses this oild chuck pressure control device, just can only finish roughing or finishing operations, thereby reduce lathe service efficiency and workpiece working (machining) efficiency to same workpiece.
Summary of the invention
For the shortcoming that the pressure control device that solves above-mentioned lathe oild chuck in use exists, the control device that the utility model provides can improve lathe service efficiency and workpiece working (machining) efficiency.
The pressure control device of a kind of lathe oild chuck of the present utility model comprises hydraulic cylinder, connecting line and reversal valve, and the same pressure conversion of described reversal valve control loop links to each other.The main effect of described pressure conversion control loop is can be for described hydraulic cylinder provides two kinds and two or more needed hydraulic pressures, so that chuck can produce the multiple chucking power that needs to workpiece.Described pressure conversion control loop can be made up of two stage pressure transformation loops, also can be made up of the multistage pressure transformation loop.Described pressure conversion control loop is preferably two stage pressure transformation loops.Because the needs of chuck to the chucking power of workpiece generation have been satisfied in two stage pressure transformation loops substantially, and are convenient to design, produce and install.
Because above-mentioned the utility model can make chuck that different workpieces is produced the chucking power that needs, so the utility model has reached the purpose that improves lathe service efficiency and workpiece working (machining) efficiency.
The beneficial effects of the utility model are to make chuck can produce the chucking power that needs to different workpieces, have improved lathe service efficiency and workpiece working (machining) efficiency.

Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structure and the fundamental diagram of the utility model embodiment.
Among the figure 1, chuck, 2, hydraulic cylinder, 3, reversal valve, 4, reversal valve, 5, pressure-reducing valve, 6, pressure-reducing valve, 7, check valve, 8, check valve, 9, the lathe hydraulic system.
The specific embodiment
As shown in Figure 1, a kind of pressure control device of lathe oild chuck comprises hydraulic cylinder (2), connecting line and reversal valve (3), and the same two stage pressure conversion control loops of described reversal valve (3) link to each other.Described two stage pressure conversion control loops are by two pressure-reducing valves (5,6), a reversal valve (4) and corresponding connecting line constitute, described two pressure-reducing valves (5,6) delivery outlet links to each other with two ports of described reversal valve (4) respectively, described two pressure-reducing valves (5,6) input port is respectively equipped with check valve (7,8).The effect of described two pressure-reducing valves (5,6) is to produce high pressure and two kinds of pressure of low pressure respectively, and the effect of described reversal valve (4) is described two pressure-reducing valves (5 of control, 6) output of the hydraulic coupling of Chan Shenging, described check valve (7,8) effect is an output pressure of stablizing described pressure-reducing valve (5,6).The hydraulic coupling input port of described reversal valve (3) is provided with the Pressure gauge (10) that is attached thereto.The effect of described Pressure gauge (10) is an output pressure of being convenient to understand pressure-reducing valve (5,6).Described reversal valve (3,4) is the electromagnetic type reversal valve.Because it is simple in structure that the electromagnetic type reversal valve has, be easy to realize control that design and installation is advantage easily.
During use, described two stage pressure conversion control loops are linked to each other with lathe hydraulic system (9).Like this under the effect of lathe hydraulic system (9), by described pressure-reducing valve (5,6) externally produce the high and low two kinds of hydraulic couplings that need, under reversal valve (4) control, flow to reversal valve (3) as required, do clamping and unclamp action by reversal valve (3) control hydraulic cylinder (2) drive chuck (1).
Claims (4)
1, a kind of pressure control device of lathe oild chuck comprises hydraulic cylinder, connecting line and reversal valve, it is characterized in that the same pressure conversion of described reversal valve control loop links to each other.
2, the pressure control device of a kind of lathe oild chuck as claimed in claim 1 is characterized in that described pressure conversion control loop is two stage pressure conversion control loops.
3, the pressure control device of a kind of lathe oild chuck as claimed in claim 2, it is characterized in that described two stage pressure conversion control loops comprise two pressure-reducing valves, a reversal valve and corresponding connecting line, the delivery outlet of described two pressure-reducing valves links to each other with two ports of described reversal valve respectively.
4, the pressure control device of a kind of lathe oild chuck as claimed in claim 3 is characterized in that described reversal valve is the electromagnetic type reversal valve.
