Abstract
The invention relates to a large-helix twisting angle detecting device, which comprises a circular cover-shaped fixed seat and an indexing plate, wherein the indexing plate is fixedly connected to the top of the fixed seat by a bolt in a circular plate shape; a bearing mounting hole is formed at the center of the fixed seat; the fixed seat is connected to a rotation guiding rod by a bearing in a matched way; the large-helix twisting angle detecting device is characterized in that a key slot in an axis direction is formed in the rotation guiding rod; one end part of the rotation guiding rod is provided with a guide pin in the radial direction; a pointer seat is arranged on the inner ring of the bearing; an alidade is fixed on the pointer seat by a bolt and overlaid above the indexing plate; and a convex block matched with the key slot of the rotation guiding rod is arranged on the alidade. According to the invention, a large-helix twisting angle can be directly detected, accurate measuring data is obtained and the machining quality of a product is guaranteed.
Description
Technical field
The present invention relates to the machining test measuring device, be specifically related to the king bolt line and twine angle detecting device.
Background technology
The detection that at present, at home the king bolt line is twined the angle is solution preferably not also.Such as the angle of rifling of gun tube, particularly become the detection twine the angle rifling, moulding measurer that can't design specialized, correctness that can only the measuring equipment pattern assert that indirectly the angle of rifling after processing is qualified, does not have accurate data.If employing digital control processing, its correctness that twines the angle can only utilize numerical control program to confirm indirectly to assert that processing is qualified, if causing helix to twine the angle, the fault of work in-process factor control system changes, to be difficult to find in process, this will cause the batch of part to scrap even underproof product stream is forwarded in user's hand, produces extremely bad impact.Therefore, it is extremely important that the king bolt line twines the detection at angle.CN 102297636A has announced " a kind of device for the twist of rifling of gun tube measurement ", this device comprises pedestal, rotating shaft, backbone sealing ring, mount pad, wireless antenna, control panel, high-precision encoder, rechargeable battery set, installation version, abutment ring etc., also comprise by path bearing, adjustable elastic pin, decide the measurement dish that circle, moving-coil and torsion spring form, this measurement dish clamps rifling and rotates together, gather the corner data by rotating shaft by high-precision encoder, control panel is processed the corner data and is launched by wireless antenna.Its measuring accuracy is high, easy and simple to handle, can realize on-line measurement, but the structure of this device is complicated.Therefore, need to look for another way, exploitation king bolt line twines the pick-up unit at angle.
Summary of the invention
The purpose of this invention is to provide a kind of king bolt line and twine angle detecting device, it can directly twine the angle to king bolt and detect, and measurement data is accurate, guarantees the crudy of product.
A kind of king bolt line of the present invention twines angle detecting device, comprise that the holder of rounded lid shape becomes discoid index plate with being fixedly connected on by screw on its top, center at described holder is provided with bearing mounting hole, described holder is connected to by bearing fit and leads on the bull stick, it is characterized in that: the described bull stick of leading is provided with keyway along axis direction, and a described end of leading bull stick radially is provided with guide finger;
The inner ring of described bearing is provided with a hand rest, and an alidade is fixed by screws on this hand rest, and overlap described index plate above; Described alidade is provided with the projection that cooperates with described keyway of leading on the bull stick.
Adopt index plate and alidade to improve reading accuracy.Index plate is 360 lattice grooves, 1 ° of scale division value, and alidade is 30 ° of 29 lattice grooves.
Described a kind of king bolt line twines angle detecting device, and its described holder fastens with the cylindrical workpiece end that is detected, and fastening by the stop screw of holder; A described end of leading bull stick that is connected with holder is stretched in the detected cylindrical workpiece, be located at the helicla flute corresponding matching of the guide finger of leading on this end of bull stick and the cylindrical workpiece inwall that is detected, stretch out outside the detected cylindrical workpiece described the other end of leading bull stick.
Beneficial effect of the present invention: it can be directly twines the angle to the king bolt of workpiece detects, and accurate recording detects the data that the workpiece spiral twines the angle, effectively controls product quality.
