Abstract
The utility model discloses a positioning mechanism, which comprises a base, a positioning block, a positioning pin and a fixing pin. The positioning block is mounted on the base by the positioning pin and the fixing pin, and a recess is disposed on the positioning block. The positioning mechanism has the advantages that a positioning shaft is positioned accurately by the aid of the positioning block, a workpiece processing hole is directly positioned by the shaft, after a workpiece is positioned and fixed, the fixing pin is detached, then the positioning block can rotate on the positioning mechanism so that the positioning block is separated from the positioning shaft, and the positioning shaft can be taken out easily so that the workpiece can be processed. The positioning mechanism is simple in structure and convenient in use, increases efficiency and guarantees quality of products.
Description
Technical field
The utility model relates to detent mechanism, particularly workpiece is carried out the required detent mechanism of machined.
Background technology
When at present workpiece being carried out machining processes such as bore hole, can't directly locate needs the hole that processes on the workpiece, can only adopt alternate manner such as location workpiece profile to hole indirect addressing usually.After the indirect addressing, still need workpiece is calibrated, with quality problems such as bore hole surplus deficiency, the boring of avoiding the hole be inclined to one side.But if can accomplish the hole that direct location will process, can reach advantages such as positioning accuracy height, bore hole deviation are little, the processing work quality is good, efficient is high.
Usually there is following problem in the method with axle location workpiece machining hole that adopts: after the workpiece positioning and clamping, locating shaft is taken out, the axle positioning seat can be interfered with borer, and the hole can't process; Detachable as if the axle positioning seat is made, can interfere with workpiece again during dismounting.
The utility model content
The utility model purpose: at the problems referred to above, the utility model will provide a kind of detent mechanism that uses simple in structure, convenient, and the positioning accuracy height helps the raising of following process quality.
Technical scheme: a kind of detent mechanism, comprise base, locating piece, also comprise alignment pin and steady pin, described locating piece is installed on the described base by described alignment pin, steady pin, has recess on the described locating piece.
Described recess is a V-type, can press from both sides steady locating shaft, and simultaneously its contact-making surface with locating shaft formation is firm, helps guaranteeing positioning accuracy.
On the described base supporting seat is set, is used for the support workpiece.
Described supporting seat is telescopic adjustment up and down, is convenient to adjust according to the situation of workpiece the height of supporting seat, it is suitably contacted with workpiece, thereby play the support effect.Locating shaft is suitably contacted with locating piece, excessive pressure can not be arranged, steady pin takes out easily behind the assurance clamping workpiece.
For making the workpiece stress equalization, described supporting seat is symmetric arrangement on described base.
After making the workpiece location, no longer be offset, keep positioning accuracy, on the described base presser device is set, Work-sheet pressing is fixed, so that the carrying out of operations such as follow-up locating shaft detaches, bore hole.
Beneficial effect: compared with prior art, the utility model has the advantages that by locating piece locating shaft is precisely located, realize directly locating the workpiece machining hole with axle, after the workpiece positioning and fixing, remove steady pin, locating piece can rotate on detent mechanism, locating piece is separated with locating shaft, locating shaft can take out easily, and workpiece is processed, and is simple in structure, easy to use, raise the efficiency and guarantee product quality.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
Shown in accompanying drawing 1 to 4, a kind of detent mechanism comprises base 1, locating piece 2, also comprises alignment pin 3 and steady pin 4, and described locating piece 2 is installed on the described base 1 by described alignment pin 3, steady pin 4, has recess 5 on the described locating piece 2.
Presser device 7 is set on the base 1, and is symmetrical arranged supporting seat 6, supporting seat 6 is telescopic adjustment up and down; Best, recess 5 be shaped as V-type.
Use the utility model detent mechanism to be: locating shaft 8 to be passed workpiece 9, then workpiece 9 is hung on detent mechanism, make locating shaft 8 be seated at recess 5 places on the locating piece 2 on both sides to the concrete steps of workpiece location; Adjust the height up and down of supporting seat 6, make between locating shaft 8 and the locating piece 2 just to contact, while locating shaft 8 can rotate, and utilizes presser device 7 workpiece pressings then; Steady pin 4 is taken out, and locating piece 2 leaves locating shaft 8 around alignment pin 3 rotations, can begin workpiece processing behind the taking-up locating shaft 8.
