Abstract
The utility model discloses a pneumatic pressure device for detecting the distance between a part and a tool. The device comprises an air inlet pipe and the tool, wherein a pressure reducing valve, a pressure sensor and an adjusting valve are sequentially arranged on the air inlet pipe, a plurality of supporting blocks are arranged on the tool and fixed to the tool, air inlet holes are formed in the supporting blocks and communicated with the air inlet pipe, and air leakage holes communicated with the air inlet holes are formed in the tops of the supporting blocks. Compared with an existing detection device, the pneumatic pressure device for detecting the distance between the part and the tool can accurately judge whether the part is installed correctly through detection, and therefore after the part is machined, the parallelism, the location degree and the size of a product meet requirements of drawing information, the quality of the product is stabilized, and production capacity in the process is improved.
Description
Technical field
The utility model relates to a kind of, relates in particular to a kind of pneumatic compression device that detects spacing between part and frock.
Background technology
When part and frock are carried out clamping, be usually lined with and add the aluminium bits that produce man-hour, cause after part processing, the depth of parallelism of product, size, position degree are overproof, cannot guarantee product quality, and be difficult to precisely detect judgement.
Utility model content
The problem existing for above-mentioned prior art, the utility model object is to provide a kind of above problem that solved, and adopts air pressure to leak principle and detects, and by machine tool numerical control system, is automatically controlled, to part, whether installation puts in place and makes a determination, and detects the pneumatic compression device of spacing between part and frock.
The technical solution of the utility model is: a kind of pneumatic compression device that detects spacing between part and frock, comprise air inlet pipe and frock, in described air inlet pipe, be provided with successively pressure-reducing valve, pressure sensor and control valve, described frock is provided with a plurality of back-up blocks, described back-up block is fixed in frock, back-up block is provided with air admission hole, and described air admission hole is communicated with air inlet pipe, and described back-up block top offers the bleeder port being communicated with air admission hole;
As preferably, described air inlet pipe is connected with the air admission hole of back-up block by the fast joint of twisting;
As preferably, the top of described back-up block and piece surface laminating;
As preferably, the operating pressure of described pressure-reducing valve is 0.15-0.2Mpa.
The beneficial effects of the utility model are: by the detection of pneumatic compression device of the present utility model, can accurately judge whether part is correctly installed, and makes after part processing, and the depth of parallelism of product, position degree, size meet drawing data requirement, stabilized product quality, has improved process production capacity.
Accompanying drawing explanation
Fig. 1 is the structural representation block diagram of the utility model embodiment;
Fig. 2 is the structural representation of the utility model embodiment contiguous block and frock.
In figure: 1. frock; 2. back-up block; 3. air admission hole; 4. bleeder port.
The specific embodiment
Embodiment: as a kind of embodiment of the present utility model, as Fig. 1, a kind of pneumatic compression device that detects spacing between part and 1 shown in Fig. 2, comprise air inlet pipe and 1, in described air inlet pipe, be provided with successively pressure-reducing valve, pressure sensor and control valve, pressure-reducing valve is controlled admission pressure, the operating pressure of described pressure-reducing valve is 0.15-0.2Mpa, control valve carries out pressure adjusting, described 1 is provided with a plurality of back-up blocks 2, described back-up block 2 is fixed on 1, the top of described back-up block 2 and piece surface laminating, the installation site of back-up block 2 is according to the surface configuration of actual parts, can rationally adjust, back-up block 2 is provided with air admission hole 3, described air admission hole 3 is communicated with air inlet pipe, described back-up block 2 tops offer the bleeder port 4 being communicated with air admission hole 3, described air inlet pipe is connected with the air admission hole 3 of back-up block 2 by the fast joint of twisting, connect easy to use.
Adopting air pressure to leak principle detects, by machine tool numerical control system, automatically controlled, whether part is installed to put in place and make a determination, by pressure sensor, detect the leakage rate of part and 1 upper support piece 2, by pressure sensor, the leakage value of the air pressure leakage rate of test point and setting (height 0.01～0.5mm during pad slag is adjustable) is compared, and then detect the clearance height of part and 1 upper support piece 2, as being greater than, setting value lathe judges defective by numerically controlled control system, procedure cannot start, the signal that lathe detects sensor changes, send alarm signal, while pressing start button, lathe is not carried out automatic running program, thereby reach the function of mistake proofing.Be less than and set value procedure and normally start.
Whether the clamping of each part is put in place, after 100% automatic detection, spot-check the situation of a week, find cannot start phenomenon 3 times, through to clamping after again cleaning in conjunction with end face, can normally start.The content of this equipment processing is carried out to the part of 50 of processing continuously and entirely examine, processing project size 100% is qualified.
