The fixing mechanism 2 and the moving mechanism 3 are uniformly distributed on the upper surface of the mounting table 1 and are respectively arranged on two sides of the mounting table 1.
The clamping devices 5 are used in pairs, respectively as a fixed-side clamping device and a moving-side clamping device, which are arranged on the end outer side plates of the fixed mechanism 2 and the moving mechanism 3, respectively, as a flange or sleeve fixing device. The fixed-side clamping device and the moving-side clamping device 5 are arranged on the fixed mechanism 2 and the moving mechanism 3 respectively in a face-to-face mode, and the positions of the central holes are overlapped.

The centering and positioning detection end seat 63 is arranged in the hollow space inside the fixing mechanism 2 and the moving mechanism 3 through a sliding seat, and the automatic centering and positioning detection device 6 can be integrally detached through detaching the sliding seat. During operation, the centering and positioning detection end seat 63 is locked, and the automatic centering and positioning detection device 6 is kept still.

The centering and positioning detection head 61 and the centering and positioning absorption body 62 are superposed with the central lines of the fixed side and moving side clamping devices 5 and are positioned in the hollow structures of the fixed side and moving side clamping devices 5. The surface of the centering detection head 61 coincides with the bottom surface of the clamping jaws of the fixed-side and moving-side clamping devices 5, which is also the fixed positioning surface for flange/sleeve clamping. After the centering and positioning is completed, the pipe is inserted into the flange or the sleeve to a certain depth S. The relative positional relationship of the pipe, the flange (sleeve), the holding claws of the fixed-side and moving-side holding devices 5, and the centering detection head 61 is as shown in fig. 6 and 7. The clamping device 5 is here preferably a three-jaw or multi-jaw chuck; the centering positioning detection head 61 is preferably a disc type plane pressure sensor; the centering suction 62 is preferably an electromagnetic suction cup. Since the disc type plane pressure sensor and the electromagnetic type sucker are both in the prior art, the working principle and the specific structure of the disc type plane pressure sensor and the electromagnetic type sucker are not repeated.
Specifically, the core of this patent lies in setting up automatic centering location detection device 6 and realizing automatic centering assembly, rather than mount table or supporting device.
Namely, the maximum improvement point of the patent technology is as follows:
at present, when the pipe is assembled with the flange or the sleeve, the pipe needs to be inserted into the flange or the sleeve to a certain depth, the specification number of the pipe is various, the insertion depth of each pipe is also different, and the clearance between the pipe and the flange or the sleeve is very small. So if automatic centering assembly is to be achieved, 2 problems have to be solved: 1) the insertion depth can be accurately controlled; 2) the pipe and flange or sleeve centerlines are completely coincident. The prior art adopts the manual work to lay the gasket in advance for solving the problem 1), and the insertion depth is indirectly controlled by controlling the thickness of the gasket. The prior art therefore has no way of achieving self-centering assembly, namely the bottleneck and pain spots of the prior art.
In addition, because the length of the sleeve is long, the depth of the pipe inserted into the sleeve is also deep, and after the assembly is completed, the gasket in the sleeve is difficult to smoothly take out, so that the time is wasted, and the defects of the prior art are overcome.
The invention solves the problems by arranging an automatic centering and positioning detection device, wherein the centering and positioning detection device comprises a centering and positioning detection head and a centering and positioning detection end seat, the centering and positioning detection head is connected with the centering and positioning detection end seat through a centering and positioning adsorption body, and the centering and positioning detection end seat is connected with the shells of the fixing mechanism and the moving mechanism.
The centering detection head is used for detecting whether the pipe reaches the required depth when the pipe is inserted into the flange or the sleeve. If the pressure sensor of the detection head has signals, the pipe is inserted in place, and the insertion depth meets the requirement.
The centering positioning of the adsorbent has 2 points: 1) when the movable end moves towards the fixed end, the pipe cannot be separated from the detection head, otherwise the insertion depth fluctuates and becomes inaccurate; 2) when the movable end needs to be far away from the fixed end, the centering positioning adsorption body can drag the pipe to move towards the far direction, if the pipe does not have the adsorption effect, the traction effect on the pipe is lost, and the automatic positioning can not be realized.
The centering and positioning detection end seat is used for bearing the centering and positioning detection head and the centering and positioning adsorption body. The device has the function of accurate movement back and forth, and realizes accurate control through servo drive.
The centering and positioning detection head, the centering and positioning adsorption body and the centering and positioning detection end seat can not be separated all the time. The centering positioning adsorption body adsorbs the tube through adsorbing the gap of the detection head, and the adsorption body can also adsorb the detection head and the tube at the same time. The centering and positioning detection head 61, the centering and positioning absorption body 62 and the centering and positioning detection end seat 63 are connected with each other through threads, and are changed, disassembled, maintained and overhauled.
2. This patent still a bit is different from prior art, and prior art centering assembly is that the pipe is motionless, and both ends clamping device drives flange or sleeve pipe and is close to the pipe. The pipe insertion depth is completely guaranteed by the thickness of the gasket, the thickness machining error of the gasket can cause the pipe insertion depth error, meanwhile, the insertion depth has no detection means, the method belongs to open loop and no feedback, and the precision is greatly influenced. This patent adopts the mode that the pipe removed, and accurate location depth of insertion belongs to closed-loop control, and is not only high-efficient accurate, labour saving and time saving simultaneously.
3. This patent still a bit is different from prior art, is exactly because designed automatic centering location detection device 6, and clamping device and prior art's clamping device are different, and prior art's clamping device middle part is solid, because need lay flange or sleeve pipe and gasket, and the location installation face of flange or sleeve pipe and gasket installation is regarded as to solid face. Clamping device's middle part is hollow in this patent, need not lay the gasket, also does not need to install the locating surface for the structure is more simple, is convenient for make reduce cost.
The foregoing is a more detailed description of the present invention in connection with specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific details set forth herein. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
