Abstract
An internal expansion alignment positioning device mainly comprises a positioning pin, an axial cylindrical mandrel arranged in the inner cavity of the positioning pin, three equal-length sliding columns which are uniformly distributed along the radial direction and are in contact with the axial cylindrical mandrel, and an axial screw. The utility model is used for the spot facing work of disk work piece, upper end position assembly bushing plate, lower extreme position and work piece hole become clearance fit. The cylindrical mandrel is in surface contact with the positioning pin, so that the clearance is small, the cylindrical mandrel is not easy to wear, the center drift is avoided, the alignment and positioning precision is improved, and the precision retention time is long. Meanwhile, springs and thread sleeves with adjustable elasticity are arranged on the three sliding columns, so that the three sliding columns can synchronously return, and the workpiece can be conveniently and quickly assembled and disassembled.
Description
Technical field
The utility model relates to a kind of Machinery Process Locating Jig, especially for the internal expanding centering positioner of plate-like workpiece hole processing.
Background technology
At present China's machining industry for plate-like workpiece the processing in uniform hole along the circumferential direction generally adopt a kind ofly with workpiece endoporus location, have the anchor clamps of bushing plate.Its primary structure is: at the steel ball that becomes the inner chamber of the alignment pin of matched in clearance to be provided with vertically to slide with the workpiece endoporus and contacted along three of the alignment pin radial equipartition isometric travellers and an axial bolt with steel ball.During the work beginning, manually the precession screw moves downward steel ball, thereby promotes radially spreading of three travellers, eliminates the gap, and the centering centre of location plays certain clamping action simultaneously.Behind the end-of-job, screw out screw, three travellers are radially return under the effect of spring retainer, draw off workpiece.But, since between steel ball and the alignment pin inner chamber for line contacts, appearance easy to wear can produce the center drift than gap greatly when promoting three traveller spreadings, influences the centering positioning accuracy; When compressing the traveller contraction by the spring retainer simultaneously,, be difficult to accomplish synchronously, make troubles for the dismounting of workpiece because the moving resistance of three travellers does not wait.
Summary of the invention
The purpose of this utility model is to overcome the weak point of existing positioning fixture, provides a kind of centering positioning accuracy height and precision retention time long, and work-handling is internal expanding centering positioner fast and easily.
The technical solution of the utility model is: internal expanding centering positioner, comprise alignment pin, be arranged on the alignment pin inner chamber sliding part and with contacted three the isometric travellers of sliding part and a screw, three travellers are along the alignment pin radial equipartition, screw along alignment pin to setting, improvements are that described sliding part is a cylindrical mandrel, and three travellers are provided with compression spring and thread bush.
The position that above-mentioned cylindrical mandrel contacts with traveller is a taper seat.
Adopt above technical scheme since between cylindrical mandrel and the alignment pin cavity for face contacts, and the gap can accomplish lessly, not easy to wear, avoided the center drift, thereby made the raising of centering positioning accuracy and the precision retention time of this device long; On three travellers spring and the thread bush that can adjust elastic force arranged all, guarantee that three travellers return synchronously, make work-handling convenient and swift.
Description of drawings
Accompanying drawing is the utility model structural representation (revolved sectional view).
The specific embodiment
With reference to accompanying drawing, bushing plate A is equipped with in the upper part of alignment pin 2, and end portion becomes with workpiece B endoporus
Matched in clearance.The alignment pin inner chamber has cylindrical mandrel 3 and contacted with it three travellers 4, a screw 1.Be respectively equipped with spring 5 and thread bush 6 on three travellers.Cylindrical mandrel and traveller contact site are taper seat.
Claims (2)
1, a kind of internal expanding centering positioner, comprise alignment pin, be arranged on the alignment pin inner chamber sliding part and with contacted three the isometric travellers of sliding part and a screw, three travellers are along the alignment pin radial equipartition, screw along alignment pin to setting, it is characterized in that described sliding part is a cylindrical mandrel, three travellers are provided with compression spring and thread bush.
2, by the described internal expanding centering of claim 1 positioner, it is characterized in that the position that cylindrical mandrel contacts with traveller is a taper seat.
