Description

Gas-liquid pressure decay checkout gear

Technical field

The utility model relates to a kind of gas-liquid pressure decay checkout gear.

Background technology

During the work of pressurize anchor clamps, the anchor clamps oil circuit separates with machine tool hydraulic system, and self forms the high pressure system of a sealing.The occasion long in the process-cycle, that caloric value is bigger, the pressure of anchor clamps oil piping system tend to descend, and for quality and the process system safety that guarantees processing work, need monitor detection and warning in time in real time to the change of anchor clamps oil pressure in the middle of the process-cycle.At present, also be not used in the gas-liquid pressure decay checkout gear of anchor clamps oil circuit and lathe baric systerm, can not guarantee the quality and the process system safety of processing work.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of gas-liquid pressure decay checkout gear is provided, this checkout gear can be monitored in real time the attenuation variation of anchor clamps oil pressure and detect and warning in time, thereby guarantees the quality and the process system safety of processing work.

The technical scheme that provides according to the utility model, in end cap, offer spring cavity, spring cavity inner opening-like, on the end cap outside the openend of spring cavity, be fixedly connected with fairlead, the fixedly connected oil cylinder seat in the other end of fairlead, be bolted with its inner on the end cap and stretch into the interior adjustment bolt of spring cavity, adjust the baffle plate that the bolt outer wall is provided with projection, be socketed with spring outside on adjusting bolt, the outer end of described spring is against on the baffle plate, on end cap, offer venthole that is communicated with spring cavity and the air admission hole that is provided with at interval with venthole, the port of export of described air admission hole is positioned on the end cap end face of openend of spring cavity, in fairlead, slidely connect the slide block of the port of export of shutoff spring cavity and air admission hole, the inner of spring is against on the end face of this slide block, and slide block and fairlead inwall are and are tightly connected, slide block with respect to the end face dorsad of spring on roof pressure the piston rod of oil cylinder, described oil cylinder is arranged on the oil cylinder seat, offers the oil supplying hole of oil cylinder on oil cylinder seat.

Offer corresponding to the end face of spring at slide block depression is installed, the inner end of described spring promptly embeds in this installations caves in.

After the utility model is installed and used, can monitor in real time the attenuation variation of anchor clamps oil pressure and detect and warning in time, guarantee the quality and the process system safety of processing work.

Description of drawings

Fig. 1 is an overall structure schematic diagram of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in the figure: in end cap 1, offer spring cavity 9, spring cavity 9 inner opening-like, on the end cap 1 outside the openend of spring cavity 9, be fixedly connected with fairlead 8, the fixedly connected oil cylinder seat 6 in the other end of fairlead 8, fairlead 8, oil cylinder seat 6 and end cap 1 link into an integrated entity by bolt 5, be bolted with its inner on the end cap 1 and stretch into adjustment bolt 3 in the spring cavity 9, adjust the baffle plate 10 that bolt 3 outer walls are provided with projection, be socketed with spring 2 outside on adjusting bolt 3, the outer end of described spring 2 is against on the baffle plate 10, on end cap 1, offer venthole 11 that is communicated with spring cavity 9 and the air admission hole 12 that is provided with at interval with venthole 11, the port of export of described air admission hole 12 is positioned on end cap 1 end face of openend of spring cavity 9, in fairlead 8, slidely connect the slide block 7 of the port of export of shutoff spring cavity 9 and air admission hole 12, the inner of spring is against on the end face of this slide block 7, slide block 7 is with fairlead 8 inwalls and is tightly connected, slide block 7 with respect to the end face dorsad of spring 2 on roof pressure the piston rod of oil cylinder 4, described oil cylinder 4 is arranged on the oil cylinder seat 6, offers the oil supplying hole 13 of oil cylinder 4 on oil cylinder seat 6.

Offer corresponding to the end face of spring 2 at slide block 7 depression 14 is installed, the inner end of described spring 2 promptly embeds this installations and caves in 14.

Operation principle of the present utility model is as follows:

Oil cylinder seat 6 adopts board-like the connection with the anchor clamps working connection, give oil cylinder 4 fuel feeding, obtain working connection pressure, rotate and regulate bolt 3, make slide block 7 left side under the effect of oil cylinder 4 thrusts and spring 2 thrusts press close to the right side of end cap 1, seal the compressed air of introducing through end cap by the lathe air inlet, when the pressure of anchor clamps working connection drops to pressure that spring 2 sets when following, spring 2 thrusts are greater than oil cylinder 4 thrusts, slide block 7 moves right, air admission hole 12 and venthole 11 on the end cap 1 communicate, and the rapid drawdown of lathe supply gas pressure can be sent warning message to control system.
