Abstract
The utility model relates to a stepped hole screw thread verticality detection device. The stepped hole screw thread verticality detection device comprises a core rod provided with two central holes at the tip parts, as well as an expansion shaft, an expansion sleeve, a clamp nut, a pressure plate and a fixing pin, which are arranged on the core rod, wherein external threads are arranged on the expansion sleeve connected onto the core rod through the fixing pin, and the clamp nut is used for pushing the pressure plate, the expansion shaft and the expansion sleeve to move, so as to enable the external threads to be expanded. The stepped hole screw thread verticality detection device provided by the utility model has the advantages of simple structure, low cost and strong practicability, and can be used for detecting the verticality of a part end surface to be detected when used with a pendulum meter, and can be used for end surface grinding and guarantee the verticality of the part end surface and the screw thread when used with an excircle grinding machine.
Description
Technical field
The utility model relates to a kind of pick-up unit of machining, specifically is the testing apparatus for verticality of part end face to the stepped hole screw thread.
Background technology
Existing internal thread verticality detects the general taper thread plug that adopts, part is screwed in the external thread plug, utilize the thread taper of plug, in having eliminated, externally threaded tolerance clearance detects beating of part end face with table again and can measure the verticality of end face double thread.The shortcoming of doing like this be detect thread taper can not be too big, the gap that needs a very long segment distance to be used for eliminating part and screw thread plug during cooperation, so can only detect the verticality of through hole whorl or slotted hole screw thread.
Summary of the invention
The purpose of this utility model overcomes above-mentioned existing shortcoming exactly, provide a kind of simple in structure, cost is low, practical, the repetitive positioning accuracy height, can accuracy of detection greater than the stepped hole screw thread testing apparatus for verticality of 0.01 thread part
The utility model is made up of the bloated axle, expansion set, gland nut, pressing plate and the fixed pin that have the top plug of two center pits and be located on this plug, and it is characterized in that: described expansion set is provided with external thread, and expansion set is connected on the plug by fixed pin; Gland nut promotes pressing plate, bloated axle and expansion set and moves, and makes the external thread distending.
The utility model is simple in structure, cost is low, practical, can detect the verticality of part end face with the supporting use of beat instrument to the stepped hole screw thread.Can carry out cross grinding processing with cylindrical grinder is supporting, guarantee the verticality of part end face and screw thread.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, gland nut,, 2, pressing plate, 3, expand axle, 4, expansion set, 5, plug, 6, fixed pin, 7, part to be measured, 8, external thread.
Embodiment
The utility model is made up of the bloated axle 3, expansion set 4, gland nut 1, pressing plate 2 and the fixed pin 6 that have the top plug of two center pits 5 and be located on this plug 5, expansion set 4 be provided with one can distending external thread 8, expansion set 4 is connected on the plug 5 by fixed pin 6.
During use part 7 to be measured is screwed in the external thread 8, adjusting gland nut 1 promotes pressing plate 2, the axle 3 that expands is moved to the left, and the final axle 3 that passes through to expand is external thread 8 distendings of expansion set 4, the gap of having eliminated internal and external threads.Locate if pick-up unit is placed on two top going up of beat instrument, just measured the verticality of part end face and screw thread by beating the table look-up part end face.
If with supporting use on the cylindrical grinder, can carry out the grinding of stepped hole screw thread end face, guarantee the verticality of part end face and screw thread.
