A pneumatic device comprises a gas source pipeline, a pressure regulating valve and a pneumatic position sensor. The gas source pipeline is connected with a gas source and connected with the pressure regulating valve. The pressure regulating valve is connected with the pneumatic position sensor through a pipeline. A gas outlet of the pneumatic position sensor is connected with a gas injection type rotary oil cylinder through a pipeline. The gas injection type rotary oil cylinder is fastened on a machine tool body through a transition disc and connected with a hydraulic chuck through a hollow pulling rod. The right end of the pulling rod is connected with a front end cover. Three gas holes are formed in the front end cover of the hydraulic chuck. Due to the structure of the chuck clamping and precision positioning determination device, the reliability of the machine tool is improved, the units can be independently assembled and replaced, the chuck clamping and precision positioning determination device is an innovation of integrating a spindle structure, the chuck and a detection device, is low in cost and failure rate and easy to maintain, and represents the development direction and popularization of precision positioning determination devices.

The specific embodiment
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
The utility model is that device is confirmed in a kind of chuck clamping precision positioning, prior device is to go to measure with dial gauge by simple original, also having one is to detect with electric switch, but this method is subject to the impact of environment to be not suitable for (dispersing, have smear metal end etc. as cooling fluid).The utility model has been broken the restriction of former conventional method, makes full use of the method that oild chuck combines with angling cylinder, can realize quick response, save the advantages such as space, low noise, is the great innovation that device is confirmed in lathe clamping precision positioning.Together with structure of the present utility model combines with chuck, be the electromechanical integrated product in one by pneumatic position sensor and frame for movement.
The precision positions that the utility model utilizes pneumatic position sensor 3, gas injection type angling cylinder 4 and the oild chuck 6 of specific optimisation design to combine is confirmed device, is mainly used in confirming the laminating degree of disk like part end face and drive end bearing bracket 8.Further can determine by the laminating degree of disk like part end face and drive end bearing bracket 8 whether workpiece 10 is stepped up.
Tradition mechanical type main axle structure is more complicated, the motor of controlling main shaft rotation needs design specialized placement location, and be fixed, motor also needs bindiny mechanism power could be flowed to main shaft, and synchronize hysteresis, reverse rotation that current various bindiny mechanisms all can produce the rotation of motor and main shaft have back clearance, overcome resistance and have in power loss, transmission and have the defect in the details such as noise.The utility model is changed from structure, has thoroughly solved above-mentioned defect, and structure is simpler, and cost is also cheap.
The utility model gas collection moves precision positions confirmation device and the integrated spindle axis that position sensor 3, gas injection type angling cylinder 4 and oild chuck 6 combine, and belongs to the innovation of Digit Control Machine Tool chuck clamping precision positioning confirmation device.Source of the gas enters pneumatic position sensor 3 by pressure regulator valve 2 and enters gas injection type angling cylinder 4, gas injection type angling cylinder 4 is arranged on one with the transition disc 5 on main axle unit, source of the gas is connected with oild chuck 6 by the pull bar 7 of center band through hole again, and pull bar 7 front ends are connected with the drive end bearing bracket 8 on chuck.Source of the gas is blown from the end face of drive end bearing bracket 8, detects by workpiece 10 and stops the pressure being produced with pneumatic position sensor 3, confirms the position of workpiece 10.Arrive machine tool system by the signal feedback of two-way electromagnetic valve again, send signal and carry out next step operation.The phenomenon that mustn't leak air in connection procedure is installed, and is all rigidity non-loosening structure.
Operating principle as shown in Figure 2.Dashed rectangle inner part represents pneumatic position sensor 3, is made up of gas bridge loop.Detect on spout S2 detector gap is provided, set handwheel S1 and make to be added in the pressure balance (P1=P2) on pressure sensor.Open as spout S2, detect pressure reduction by pressure sensor.Upper near detecting spout (spout S2) when workpiece, back pressure P2 rises.In the time of P2 >=P1, switch output ON, is detecting below gap, and just there is output outside.
Source of the gas enters pneumatic position sensor 3 by pressure regulator valve 2 and enters gas injection type angling cylinder 4, the pull bar 7 of gas injection type angling cylinder 4 connecting band through holes, then pull bar 7 is connected with the drive end bearing bracket 8 in the middle of oild chuck 6, and the end face of drive end bearing bracket 8 has the venthole of three φ 1.5mm that all distribute.In the time of gripper chuck clamping of workpieces, together with the end face of workpiece 10 fits tightly with the end face at drive end bearing bracket 8 venthole places.Blowing in hole by drive end bearing bracket 8, detects by workpiece 10 and stop that the pressure being produced confirms the position of workpiece 10.For preventing that smear metal end from stopping up entering of hole on end cap and cooling fluid, while detection, also should blow.
The utility model is except possessing the advantage that conventional method cannot realize, also be beneficial to the reliability that improves lathe, each unit can be assembled separately and change, it is the innovation that main axle structure, chuck and checkout gear are integrated, have that cost is low, the advantage of failure rate is low, easy care, representing that precision positioning confirms the developing direction of device and popularize.
