Abstract
The utility model discloses a kind of testing agency of floating, comprise floating detection head, anti-striker and main shaft, the detection head that floats is connected with floating test rod and forms entirety, the detection head that floats is provided with projection, the outside of floating detection head is provided with floating tolerance part, float tolerance part and floating detection head close contact, and the tolerance part that floats is connected with outside the top of main shaft by main stop collar, floats and has gap between tolerance part and main stop collar; Float the end face of tolerance part and inner attrition piece and outside friction disc close contact.The beneficial effects of the utility model are detect form tolerance and the position of related features of rotary work piece respectively; Accuracy of detection is high; Can automatically reset, reduce labour.
Description
Technical field
The utility model design mechanical dimension testing tool, is specifically related to a kind ofly to float testing agency for detecting tubular workpiece.
Background technology
At present, known pick-up unit is by test side, the axis of guide, and without oily lining, bearing, handle forms.Driving handle detects and allows test side detect part, together with its own tolerances of part merges with Tolerance of Degree of position by this traditional detection mode, comprehensively cannot detecting its own tolerances of part, causing the undesirable part of part its own tolerances also by detecting, follow-up assembling can be affected.
Summary of the invention
For solving the problem, the utility model provides a kind of testing agency of floating, comprise floating detection head, anti-striker and main shaft, anti-striker is provided with at the omoplate place of main shaft, the detection head that floats is connected with floating test rod and forms entirety, the detection head that floats is provided with projection, the outside of floating detection head is provided with floating tolerance part, float tolerance part and floating detection head close contact, the tolerance part that floats is connected with outside the top of main shaft by main stop collar, main stop collar has the cavity matched with floating tolerance part, and there is equidistant gap in the outside of cavity and floating tolerance part; Float the end face of tolerance part and inner attrition piece and outside friction disc close contact.
Further, stop collar is connected by spring with inner attrition piece, and spring wrap is in the outside of floating test rod.
The beneficial effects of the utility model are: form tolerance and the position of related features that can detect rotary work piece respectively; Accuracy of detection is high; Can automatically reset, reduce labour.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Wherein, 1. float detection head, and 2. float tolerance part, 3. main stop collar, 4. inner attrition piece, 5. outside friction disc, 6. anti-striker, 7. spring, 8. stop collar, 9. main shaft, and 10. float test rod.
Embodiment
As shown in Figure 1, the utility model provides a kind of testing agency of floating, comprise floating detection head 1, anti-striker 6 and main shaft 9, anti-striker 6 is provided with at the omoplate place of main shaft 9, the detection head 1 that floats is connected with floating test rod 10 and forms entirety, the detection head 1 that floats is provided with projection, the outside of floating detection head 1 is provided with floating tolerance part 2, float tolerance part 2 and floating detection head 1 close contact, the tolerance part 2 that floats is connected with outside the top of main shaft 9 by main stop collar 3, the tolerance part 2 that floats is connected with outside the top of main shaft 9 by main stop collar 3, main stop collar 3 has the cavity matched with floating tolerance part 2, there is equidistant gap in the outside of cavity and floating tolerance part 2, float the end face of tolerance part 2 and inner attrition piece 4 and outside friction disc 5 close contact.
The distance of floating between tolerance part 2 and main stop collar 3 is the position of related features value of workpiece, the bump sizes of floating on detection head 1 is the allowance below nominal size of workpiece diameter and tolerance, during use, by the endoporus of the protruding tubular workpiece on floating detection head 1, its own tolerances of tubular workpiece can be found out; If tubular workpiece has position of related features, then the detection head 1 that floats drives the tolerance part 2 that floats to offset, then can find out the position of related features of tubular workpiece; If the projection of floating on detection head 1 can not go deep into the endoporus of tubular workpiece, tubular workpiece is defective; After unloading tubular workpiece, drive interior friction member 4 by spring 7, thus drive floating tolerance part 2 and floating detection head 1 to get back to original position.
