The traditional front-mounted cylinder chuck seat is formed by mounting an independent chuck seat and a rear-mounted cylinder, but the traditional rear-mounted cylinder is high in fake device cost and complex in assembly process, and is difficult to achieve high precision due to the fact that the traditional front-mounted cylinder chuck seat is required to be connected with a flange plate and a pull rod during assembly. In addition, the rear-mounted cylinder occupies a large space and is heavy, the operation performance of machinery is influenced, the service life of the chuck seat is short, and the use cost is high.
An ultra-high pressure cartridge is shown, comprising a cartridge body 100, a cylinder liner 200, a pull rod piston 206, and a back cover plate.
The collet base body 100 includes a front end body and a rear end body which are integrally formed, and in the industry, the shape of the collet base body 100 is basically the same as that shown in fig. 2, and here, for convenience of description, the collet base body is divided into two parts, namely, a front end body and a rear end body.
Three grooves are arranged on the side surface of the front end body, and the grooves comprise sealing grooves 208 for placing sealing rings and vent grooves 209 for arranging air holes. The depth of the seal groove 208 is greater than the depth of the vent groove 209. An O-shaped sealing ring is arranged in the sealing groove 208 to play a role in sealing.
The cylinder liner 200 is installed outside the three grooves and sealed by O-rings in seal grooves 208. A spindle bearing 205 is provided between both ends of the cylinder liner 200 and the side surface of the chuck base body 100, and the inner wall of the upper side of the cylinder liner 200 is fixed in contact with the outer ring of the bearing to keep the bearing stable.

When the clamping head base is used, the clamping head base body 100 moves along with a clamping head, the cylinder sleeve 200 does not move, and the O-shaped sealing ring can form a layer of oil seal on the surface in the operation process, so that the friction force between the clamping head base body 100 and the cylinder sleeve 200 in the movement process can be very small, meanwhile, the sealing performance can be completely guaranteed, the sealing mode is changed, the size of the whole clamping head base is smaller, the sealing performance is better, and the rigidity is better.
The vent grooves 209 are provided with air holes, and a plurality of air holes can be arranged in each vent groove 209, and the air inlet pipe joint on the cylinder sleeve 200 is used for ventilating the vent grooves 209 instead of fixedly ventilating a certain air hole. Since the two air grooves 209 are completely sealed, two air inlet pipe joints are required, one air groove 209. In the interior of the chuck base body 100, the air inlet ducts connected to the air holes may be different, so that the two air ducts are completely independent without any interference.
The inside terminal surface of rear end body is provided with the ring shape exhaust passage with chuck base body 100 coaxial axle center, is provided with exhaust hole 214 and spring hole 212 on the exhaust passage, and exhaust hole 214 is along the internal diameter direction to with outside intercommunication, the exit end is provided with end cap hole flat bottom bolt, as the quick exhaust gas hole of gas.
An air inlet pipe joint 204 is arranged on the cylinder sleeve 200, and the air inlet pipe joint 204 is communicated with an air inlet channel and used for ventilating the piston air containing cavity chamber through the air inlet channel so that the pull rod piston 206 moves backwards. The air inlet channel is formed by drilling from the outside, and considering that when the chuck base body 100 is machined in this way, the air channel formed is composed of a plurality of straight channels. The air inlet channel comprises four straight channels which are connected end to end and comprises an air inlet channel I2061, an air inlet channel II 2062, an air inlet channel III 2063 and an air inlet channel IV 2064.

The whole first air inlet channel 2061, the second air inlet channel 2062, the third air inlet channel 2063 and the fourth air inlet channel 2064 form a single channel, air flow enters from the air inlet connector, flows into the first air inlet channel 2061, the second air inlet channel 2062, the third air inlet channel 2063 and the fourth air inlet channel 2064 in sequence, air flow thrust is realized to a cavity between the pull rod piston and the rear cover plate, the disc spring is compressed, and therefore the whole pull rod piston is pushed forward, and a chuck is loosened. When the gas is replayed, the pull rod piston is pushed backwards by the thrust of the thrust mould spring, and the chuck is pulled tightly. In the application, after the whole air passage is changed into the single air passage, the ordinary air compressor generally cannot meet the ultrahigh pressure requirement, so that the ultrahigh pressure air compressor is adopted, and the pressure of the ultrahigh pressure air compressor can reach 12-30 MPA.
The rear cover plate is mounted at the rear end of the rear end body through bolts. A rear cover plate air accommodating cavity 403 is formed between the rear cover plate and the pull rod piston 206, and after the rear air inlet pipe is ventilated, the rear cover plate air accommodating cavity 403 exerts reaction force on the piston because the rear cover plate is fixed with the rear end body. In terms of sealing, sealing rings are arranged on the surface where the rear cover plate is connected with the rear end body and the surface where the pull rod piston 206 is connected with the rear cover plate, so that the rear cover plate air containing cavity 403 is kept sealed. The air storage capacity in the cavity is increased between the rear cover and the piston, so that the thrust is increased.
In order to increase the pressurization effect of the high pressure gas, a plurality of springs are arranged between the chuck base body 100 and the pull rod piston 206, so that the dual protection effect can be achieved, and the piston is prevented from moving too fast to impact the chuck base body 100. In the specific actual installation, according to the thrust requirement of difference, can increase or reduce the quantity of spring, but the thrust spring mounting hole does not reduce, and the hole that adds out is used as the gas storage chamber, has increased thrust spring intracavity gas storage volume, makes clamping-force increase volume further reduce.
A chuck is arranged in the chuck seat body 100, and the bottom of the chuck is fixed in the pull rod piston 206 through a flat-bottomed bolt. The inside of the drawing piston is provided with special-shaped trapezoidal threads screwed with a chuck for clamping a workpiece, and the angle is-5 to +45 degrees, namely the included angle between one thread surface and the cross section of the drawing piston 206 is 45 degrees, and the included angle between the other thread surface and the cross section of the drawing piston 206 is 50 degrees.
The rear end side of the chuck seat body 100 is provided with a step position for turning around the grinding machine. The rear end face of the rear cover plate is provided with a rear cover plate step position.
All set up the sealing washer in seal groove 208 and each needs use sealed place in this application, this structure makes this application focus on the chuck motion under the low-speed more, realizes perfect inside seal through the structure of sealing washer for the air current in the air flue can be more fast steadily exert the effort in inside to pull rod piston 206.
