Description
Technical field
The utility model belongs to jig field, and in particular to a kind of fixture of numerically controlled lathe.
Background technology
In order to ensure machining accuracy of the part on lathe, especially for the part of Internal hole positioning, usual lathe is matched
Standby tensioner collet, using tensioner collet, there are following problems：First, the unicity of collet, often covering tensioner collet can only add
One product of work；Second, collet is easy to wear during long-time use, unstable to the product size processed, serious wear
Processing can only be scrapped, it is of high cost；Third switches product every time, needs replacing different collets, and collet is fixed at fixture
On, step trouble is replaced, a large amount of time, man power and material is wasted, is further improved.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts, provide it is a kind of it is simple in structure, be convenient for changing holder, life
Produce the fixture of numerically controlled lathe at low cost.
The utility model adopts the following technical solution：
The leading portion of a kind of fixture of numerically controlled lathe, including pedestal, collet and tension mechanism, pedestal can phase including at least two
To the fission of spreading, collet includes the fixture block for being detachably arranged at each seperated front end, and tension mechanism is used to make the leading portion of pedestal
Spreading drives collet tensioner workpiece to complete the clamping of workpiece.
Further, the leading portion of the pedestal is formed with cone tank, and the tension mechanism has and can stretch into cone tank
Conical head, conical head stretch into cone tank the leading portion spreading so that the pedestal.
Further, the tension mechanism includes tension shaft, the driving device that moves along its axis of driving tension shaft and sets
Set the conical head in tension shaft front end.
Further, the driving device is cylinder.
Further, the fixture block include be arranged the seperated front end mounting portion and the folder in mounting portion front end is set
Hold portion.
Further, the fixture block is detachably arranged at seperated front end by retaining mechanism, and retaining mechanism includes that setting exists
The screw hole opposite with perforating and the bolt across perforation and screw hole cooperation is arranged on fission in perforation on fixture block.
From the above description of the utility model, it can be seen, compared with prior art, the utility model has the beneficial effects that：Folder
Seat includes the fixture block for being detachably arranged at each seperated front end, need to only be replaced corresponding holder according to different products, be not required to
Entire fixture is replaced, substitute mode is simple, can save a large amount of time, man power and material, and be when abrasion occurs in fixture block,
The fixture block of abrasion is only needed to change, ensures the stability of product processing, reduces the expenditure of cost；Retaining mechanism includes being arranged in fixture block
On perforation, be arranged on fission with the opposite screw hole and across the bolt of perforation and screw hole cooperation of perforating, facilitate the peace of fixture block
The time of installation and removal is saved in assembly and disassembly.
Description of the drawings
Fig. 1 is cross-sectional view when fixture is in running order；
Fig. 2 is the enlarged drawing at A in Fig. 1；
Fig. 3 is cross-sectional view when fixture is in off working state；
Fig. 4 is the enlarged drawing at B in Fig. 3.
Specific implementation mode
The utility model is further described below by way of specific implementation mode.
Shown in referring to Fig.1, a kind of fixture of numerically controlled lathe, including pedestal 1, collet 2, tension mechanism and retaining mechanism；
The leading portion of pedestal 1 includes at least two can be with respect to the fission 11 of spreading, specifically, the leading portion of pedestal 1 is formed with cone
Shape slot 12, further, the cross section of pedestal 1 is circle, and there are four 11 settings of fission, four 11 circle distribution of fission settings；
Collet 2 is detachably arranged on pedestal 1, including is detachably arranged at the fixture block 21 of each seperated 11 front end, specifically
, fixture block 21 include be arranged seperated 11 front ends mounting portion 211 and the clamping part 212 in 211 front end of mounting portion is set；
Tension mechanism is used to make the leading portion spreading of pedestal 1, and 2 tensioner workpiece of collet is driven to complete the clamping of workpiece, specifically,
Tension mechanism includes that the driving device (in figure for show) that tension shaft 31, driving tension shaft 31 move along its axis and being arranged is rising
31 front end of mandrel can stretch into the conical head 32 in cone tank 12, and conical head 32 stretches into cone tank 12 so that the leading portion of pedestal 1 rises
It opens, then collet 2 is driven to step up the clamping that workpiece completes workpiece；Further, driving device is cylinder；
Retaining mechanism setting is between fission 11 and fixture block 21, specifically, retaining mechanism includes being arranged on fixture block 21
Perforation 31, the bolt 33 that opposite with perforation 31 screw hole 32 on fission 11 is set and is coordinated with screw hole 32 across perforation 31；
It when work, drives tension shaft 31 to move along its axis by cylinder, the edge in cone tank 12 of circular cone 32 is driven to rise
The axial movement of mandrel 31, so that the leading portion spreading of pedestal 1, finally drives collet 2 to step up the clamping that workpiece completes workpiece, holder
2 include the fixture block 21 for being detachably arranged at each seperated 11 front end, only need to replace corresponding holder 2 according to different products,
Entire fixture need not be replaced, substitute mode is simple, can save a large amount of time, man power and material, and when fixture block 21 occurs
Abrasion is only to need to change the fixture block 21 of abrasion, ensures the stability of product processing, reduces the expenditure of cost；Retaining mechanism includes
Opposite with perforation 31 screw holes 32 on fission 11 are arranged and across perforation 31 and screw hole in the perforation 31 that is arranged on fixture block 21
The bolt 33 of 32 cooperations, facilitates the installation and removal of fixture block 21, saves the time of installation and removal.
The above, the only preferred embodiment of the utility model, therefore the utility model implementation cannot be limited with this
Range all should still belong to this that is, according to equivalent changes and modifications made by present utility model application the scope of the claims and description
In the range of utility model patent is covered.
