Description
Technical field
The utility model is related to a kind of lathe centre.
Background technology
At present in mechanical processing industry, lathe has become used in modern mechanical processing the most frequently work
Tool.When being processed to axial workpiece, in addition it is also necessary to install supporting top on lathe, with positioning shaft parts, and band
Dynamic part rotates at a high speed, cutter is conveniently processed.Axial workpiece has many types, different long in processing with a machine tool
During the axial workpiece of degree, need to top that be adjusted just can be with positioning shaft parts.
Need Jing often to adjust the occasion of top position at some, the screw mandrel abrasion of traditional employing thread connecting mode compared with
Hurry up, top positioning can be caused not tight and moved, therefore not enough fasten during top positioning processing part.Additionally, this by screw thread
The structure of cooperation, limits the top translational speed when adjusting, and makes the position adjustments of rolling center and needs to take a long time,
Reduce production efficiency.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, there is provided a kind of lathe centre, can conveniently adjust top
The process of point and the accuracy of the top positioning of guarantee.
To solve above-mentioned technical problem, the utility model employs a kind of lathe centre, including fixed seat, top, top
Set, push rod and locking key, wherein, the center sleeve level is fixed in the fixed seat, and the top level is located at described
It is slidably matched in center sleeve and therebetween, the push rod level is located at the top inside and is slidably matched therebetween, institute
State push rod and be provided with skewed slot, the center sleeve is provided with locking slot, and the lower end of the locking key is slidably matched with the skewed slot, should
The upper end of locking key is placed in the top set through hole, the locking key and the through hole axial sliding fit, described
Also level is provided with stopper slot on push rod, and limited block is fixed with the center sleeve, and the limited block is passed through described top and stretched into
In the stopper slot, the left end of the push rod is provided with fixed plate, the fixed plate and it is described it is top between be provided with thrust spring, institute
State thrust spring to be sheathed on the push rod.
Further, in above-mentioned technical proposal, the push rod is provided with handle.
The utility model is had the advantage that：Install top using not threaded center sleeve, center sleeve with it is top
Between there is no screw thread cooperation, top movement is driven by moving horizontally for push rod, while the setting of locking key can be realized
It is top be moved to appropriate location when locking to its position, with good fixed workpiece and the characteristics of registration.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：Fixed seat 1；Top 2；Center sleeve 3；Push rod 4；Locking key 5；Skewed slot 6；Locking slot 7；Stopper slot 9；Limited block
10；Fixed plate 11；Thrust spring 12；Handle 13.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model provides a kind of lathe centre, including fixed seat 1, top 2, center sleeve 3, push rod 4
With locking key 5, wherein, the level of center sleeve 3 is fixed in fixed seat 1, and top 2 level is in the center sleeve 3 and therebetween
It is slidably matched, the level of push rod 4 is located at top 2 inside and is slidably matched therebetween, and push rod 4 is provided with skewed slot 6, on center sleeve 3
Locking slot 7 is provided with, lower end and the skewed slot 6 of locking key 5 are slidably matched, and the upper end of the locking key 5 is placed in through hole set on top 2
It is interior, locking key 5 and through hole axial sliding fit, also level is provided with stopper slot 9 on push rod 4, and on center sleeve 3 limited block is fixed with
10, through top 2 and stretching in stopper slot 9, the left end of push rod 4 is provided with fixed plate 11 to limited block 10, fixed plate 11 with top 2 it
Between be provided with thrust spring 12, thrust spring 12 is sheathed on push rod 4, and push rod 4 is provided with handle 13.
Driving handle 13, push rod 4 drives top 2 to move right by thrust spring 12, when locking key 5 is moved to locking slot
During 7 low order end, top 2 stop movement, and push rod 4 moves right, and by the cooperation of skewed slot 6 and locking key 5, realize locking key 5
Abutting to center sleeve 3, top 2 position is locked；Reverse drive push rod 4 afterwards, push rod 4 is moved to left, and locking key 5 loosens top
State of the set 3, top 2 with center sleeve 3 in mutually loosening, top 2 retreat with moving to left for push rod 4, and workpiece is relaxed.
Specification and drawings of the present utility model are considered as illustrative and not restrictive, on the utility model basis
On, those skilled in the art are according to disclosed technology contents, it is not necessary to which performing creative labour just can be to some of them technology
Feature makes some and replaces and deform, in protection domain of the present utility model.
