Abstract
A jig assisting in machining an inner bore of a lock shell of an electric door lock comprises a workpiece base and a spiral shaft sleeve. The spiral shaft sleeve is arranged on the workpiece base and goes up and down perpendicularly relative to the workpiece base. The shape of a port of the lower end of the spiral shaft sleeve is an axial outward-protruding circle, and the top of the spiral shaft sleeve is provided with a handle controlling lifting of the spiral shaft sleeve. According to the jig, the lifting type spiral shaft sleeve with the lower end portion being capable of stretching in a lock shell inner cavity port is used, the shaft sleeve is matched with the workpiece base arranged relative to the shaft sleeve to vertically clamp and locate a workpiece. In operation, a reamer of a bench drill stretches to an inner cavity of the workpiece through a spiral shaft sleeve hole to machine a small circle formed by four arc faces. Therefore, concentricity of the small circle and an upper portion large circle is well guaranteed.
Description
[technical field]
The utility model belongs to the anchor clamps of a kind of auxiliary bench drill fraising operation, and a kind of anchor clamps of assisted electric vehicle electric door lock lock housing endoporus processing especially are provided to electric vehicle lock set manufacturing enterprise.
[background technology]
Referring to Fig. 1.In the blank process of processing electric motor car electric door lock lock housing a, utilizing the bench drill reamer that the cambered surface b of four vertical muscle in the blank inner chamber is carried out the fraising operation is vital operation together, because, only have cooperating by these four vertical muscle and lock core locking plate, could realize the function of opening different locks with different keys, if four formed roundlets of cambered surface b can not with the inner chamber opening's edge on great circle c(be used for admitting the bulge loop of lock core end face) concentric, that trickle deviation I guess occurs, the mutual opening rate of lockset will be increased substantially, and have a strong impact on product quality.Before the utility model is made, common processing method be with workpiece be lock housing vertically to the below that is positioned at the bench drill reamer, then, the control reamer stretches into the blank inner chamber of lock housing a from top to bottom, and four formed roundlets of cambered surface b are processed.This method is because reamer lower self can the vibrations that run up, just is difficult to guarantee the concentricity of two circles.
[summary of the invention]
For solving the problems of the technologies described above, the utility model aims to provide a kind of anchor clamps of auxiliary electrical door lock lock housing endoporus processing, and is auxiliary lower to bench drill processing lock housing endoporus at these anchor clamps, has two circle good concentricity, can control the advantage of endoporus processing dimension.
For solving the problems of the technologies described above, the utility model has adopted following technical proposals, the anchor clamps of this auxiliary electrical door lock lock housing endoporus processing is characterized in that: comprise a workseat, and a spiral sleeve that is positioned at this workseat top and relative its vertical lift of energy; The port shape of described spiral sleeve lower end is an axial outer dome; The top of described spiral sleeve is provided with the handle of its lifting of control.
During as preferred implementation, described workseat is fixedly installed on the slide block, and this slide block is embedded in the slideway of a base plate.
During as preferred implementation, described spiral sleeve is arranged on one by in the fixing sleeve block of gripper shoe.
Beneficial effect: compared with prior art, the utility model utilizes a bottom can stretch into the lift spiral sleeve of lock housing lumen port, and this axle sleeve cooperates with the workseat that it is oppositely arranged, and up and down Workpiece clamping is located.During operation, the reamer of bench drill extends workpiece lumen through the helical axis trepanning, and four formed roundlets of cambered surface are processed, and therefore, can guarantee well the concentricity of two circles.
By an embodiment, the utility model is described in further detail below in conjunction with accompanying drawing.
[description of drawings]
Fig. 1 is the perspective view of electric motor car electric door lock lock housing workpiece.
Fig. 2 is the perspective view of an embodiment of the utility model.
Fig. 3 is the descending vertical profile structural representation during near workpiece of spiral sleeve among Fig. 2.
Among the figure: lock housing a, cambered surface b, great circle c.Slide block 1, workseat 11, slideway 12, base plate 2, spiral sleeve 3, inner hole of shaft sleeve 31, outer dome 311, handle 4, sleeve block 5, gripper shoe 6.
[specific embodiment]
Referring to Fig. 2, and in conjunction with Fig. 3.These anchor clamps are by the base plate 2 that has slideway 12, the sleeve block 5 that is embedded in slide block 1 in the slideway 12, is fixedly installed by gripper shoe 6, and consist of with the spiral sleeve 3 of handle 4.Workseat 11 is arranged on the slide block 1, after slide block 1 slips into the workpiece district, workseat 11 be positioned at spiral sleeve 3 under.Add man-hour, at first workpiece lock housing a is enclosed within that (this workpiece has a hole in the bottom relative with lock housing a on the workseat 11, the dome of workseat 11 can just be admitted in this hole), swinging handle 4, make spiral sleeve 3 descending, until axially outer dome 311 stretches in the workpiece lock housing a opening's edge great circle c, compress fix lock housing a after, the operation bench drill comes downwards to by in above-mentioned four formed roundlets of cambered surface b reamer warp beam sleeve endoporus 31, twists wall processing.
Present embodiment only is explanation technology contents of the present utility model, and any simple deformation design of making according to present embodiment all should be included protection domain of the present utility model in.
