Description

A kind of lathe four-way precise locating fixture
Technical field
The utility model belongs to metal processing sectors, especially a kind of lathe four-way precise locating fixture.
Background technology
In the processing of tubular major axis metal works, especially customize in the special processing of non-standard workpiece, still need Semi-automatic controlling machine manual control device position is used, due to the gravity influence in itself of the effect of cutter and workpiece, may There is eccentric situation, cause crudy unqualified, or even whole workpiece can be caused to scrap, cause processing cost to lose.For Bad student's deviation is avoided, it is necessary to artificial repeatedly adjustment chuck, measurement processing axle center, technique is relatively complicated, and expends the time, plus Work is less efficient.
Utility model content
The purpose of this utility model be overcome the deficiencies in the prior art part, there is provided a kind of simple structure, it is reasonable in design, It is easy to operation, accurately and reliably lathe four-way precise locating fixture.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of lathe four-way precise locating fixture, it is characterised in that:Including fixture mount, lower clip arm, upper clip arm, positioning Post and adjusting screw, fixture mount upper end are formed with the lower clip arm of the semicircular arc that a upper end is opening, the radial direction of the lower clip arm One end is hinged with upper clip arm by hinge, and upper clip arm is relative with lower clip arm to form an annular holder when fastening, and workpiece is by marmon clamp The center of tool passes through;Four positioning of radial direction are installed uniformly at intervals inside the annular holder that upper fixture and lower clamp are formed Post, one end of locating dowel penetrates the inside of annular holder and a nylon cushion block is internally fixed with termination, locating dowel it is another One end rotary spacing has the adjusting screw in an outside for passing annular holder, and adjusting screw is engaged by screw thread and is arranged on upper clip arm Or the outside of lower clip arm.
And, the fixture mount bottom is rotated coaxially in a support shaft, and the support shaft is packed in a bottom vertically On seat, bolt hole is preset on base.
And, it is movably installed with connecting bolt in the radial direction other end of upper clip arm and lower clip arm.
And, locating dowel passes through the end that annular nested structure rotary spacing is arranged on adjusting screw, locating dowel and regulation Screw can be rotated and can not relatively moved.
And, a banking pin is symmetrically installed with the annular holder of both sides before and after the locating dowel, banking pin is corresponding A slide-and-guide groove is formed with locating dowel.
Advantage of the present utility model and good effect are:
It is the utility model simple structure, easy to operate, positioning work can be fastened with four length of locating dowel of accurate adjustment Part, from the center of accurate limiting workpiece, is effectively ensured the axiality of workpiece work in-process, it is ensured that machining accuracy, and lifting adds Work efficiency rate.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model;
Fig. 2 is the utility model locating dowel local radial sectional view.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment, and following examples are to retouch The property stated, be not limited, it is impossible to limit protection domain of the present utility model with this.
A kind of lathe four-way precise locating fixture, including base 8, fixture mount 7, lower clip arm 6, upper clip arm 2, locating dowel 3 and adjusting screw 1, bolt hole is preset on base, can be used to be fixed on work top, it is fixed with vertically in base upper end There is a support shaft 9, the top of the support shaft rotates coaxially and is provided with a fixture mount 7, can be with rotary clamp according to processing needs Direction;
The fixture mount upper end is formed with the lower clip arm 6 of the semicircular arc that a upper end is opening, radial direction one end of the lower clip arm Upper clip arm 2 is hinged with by hinge 10, upper clip arm is relative with lower clip arm to form an annular holder when fastening, and workpiece is by annular holder Center pass through;Be movably installed with connecting bolt 4 in the radial direction other end of upper clip arm and lower clip arm, it is ensured that in processing upper clip arm with Lower clip arm forms a fixed connection.
In order to limit the position of workpiece, four are provided with uniformly at intervals inside the annular holder that upper fixture and lower clamp are formed The locating dowel 3 of individual radial direction, one end of locating dowel penetrates the inside of annular holder and a nylon cushion is internally fixed with termination Block 12 prevents from crushing workpiece, and the other end rotary spacing of locating dowel has the adjusting screw 1 in an outside for passing annular holder, regulation Screw engages the outside installed in upper clip arm or lower clip arm by screw thread, and rotating adjusting screw can radially outward or inwardly move It is dynamic;
Locating dowel passes through the end that annular nested structure rotary spacing is arranged on adjusting screw, locating dowel and adjusting screw energy Enough rotate and can not relatively move, referring to shown in accompanying drawing.
The present apparatus is applied to the workpiece that processing dimension is smaller and precision is higher, in order to further limit the position of locating dowel Accuracy, is symmetrically installed with a banking pin 5 before and after the outer wall of locating dowel on the annular holder of both sides, and banking pin is corresponding fixed A slide-and-guide groove is formed with the post of position, effectively limitation locating dowel accurate radial direction according to annular holder in conciliation is moved It is dynamic.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, those skilled in the art can be with Understand:Not departing from the utility model and spirit and scope of the appended claims, various replacements, change and modifications all be can Can, therefore, scope of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.
