Abstract
The utility model relates to a quick replacement tool which comprises a quick replacement installation spindle, a resetting spring, a limit pin, a stop collar, a plurality of steel balls and a quick replacement workpiece. A shaft hole matched with the end of the quick replacement workpiece is formed in one end of the quick replacement installation spindle axially, a plurality of inner holes are formed in the quick replacement installation spindle radially, the steel balls are arranged in the inner holes, and grooves matched with the steel balls are formed in the quick replacement workpiece radially. The installation surface of the stop collar is of a wedge-shaped surface structure, the stop collar, the resetting spring and the limit pin are arranged on the quick replacement installation spindle in sequence, the position of the stop collar on the quick replacement installation spindle is limited by the limit pin, the stop collar presses the steel balls all the time, and a wedge-shaped gap of the stop collar and the quick replacement installation spindle is smaller than the diameter of each steel ball. By means of the quick replacement tool, a traditional structure is simplified, the spring and the pin are utilized to perform limitation and self resetting, therefore, the original structural features are improved, and the structure is more humanized. In addition, the quick replacement tool is wide in application range, simple in operation and applicable to the high-precision field.
Description
Technical field
The utility model relates to the fast replacing device of machine industry, for replacing, the quick change of equipment etc. of gas-tpe fitting, particularly a kind of quick-change tool for high accuracy field.
Background technology
Quick-change tool is a kind of at current widely used device, it plays vital effect at machinery industry, the quick change of fixture, the quick change of gas-tpe fitting, the quick change of equipment etc., utilize quick change to solve numerous complicated and loaded down with trivial details operation, save the time, saved cost, and unified standard, facilitated dismounting, quick-change tool has become the requisite constructional device of machinery industry.
At present, most of quick-change tool of domestic employing adopts the modes such as being threaded of hydraulic pressure, pneumatic, spring, screw and nut and pin connection more, can realize and change fast our needed various operations by these modes, but these quick-change tools exist more, manufacturing cost is higher or disassembling, assembling and replacing is more complicated, and the scope of application is less, the shortcomings such as precision is lower, still have a lot of areas for improvement.
Utility model content
The technical problems to be solved in the utility model is: change the problems such as complicated, cost is high, precision is low, the scope of application is less in order to overcome existing quick-change tool, provide a kind of simple and reasonable, safe and reliable, the scope of application is wide, simple to operate and can be used for the quick-change tool in high accuracy field.
The utility model solves the technical scheme that its technical problem adopts: a kind of quick-change tool, comprise quick change installation main shaft, back-moving spring, spacer pin, stop collar, several steel balls and a quick change workpiece, quick change is installed main shaft one end and is axially had the axis hole identical with quick change workpiece termination, quick change is installed main shaft diameter to having several endoporus, steel ball is installed in endoporus, quick change workpiece radially has the groove that steel ball coordinates, stop collar installed surface is lozenges structure, quick change is installed on main shaft mounting limit cover successively, back-moving spring and spacer pin, limit the position of stop collar at quick change installation main shaft by spacer pin, stop collar is pushed down steel ball all the time, the wedge gap that stop collar and quick change are installed main shaft is less than diameter of the steel ball.
Back-moving spring between described stop collar and spacer pin distance is less than lozenges length in stop collar, spacing for steel ball.
The beneficial effects of the utility model are: quick-change tool structure of the present utility model is not only simplified traditional structure, and use spring and pin to carry out spacing and Self-resetting, have improved original design feature, make the hommization more of this structure; The scope of application is wide, safe and reliable, simple to operate and can be used for high accuracy field.
Brief description of the drawings
Fig. 1 is the utility model structural representation
Fig. 2 is the stereogram after the utility model is cut open
Fig. 3 is use state diagram of the present utility model
In figure: 1, quick change is installed main shaft, 2 spacer pins, 3, back-moving spring, 4, stop collar, 5, steel ball, 6, quick change workpiece.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1, shown in 2, a kind of quick-change tool, comprise quick change installation main shaft 1, back-moving spring 3, spacer pin 2, stop collar 4, several steel balls 5 and a quick change workpiece 6, quick change is installed main shaft 1 one end and is axially had the axis hole identical with quick change workpiece 6 terminations, quick change is installed main shaft 1 and is radially had several endoporus, steel ball 5 (endoporus and steel ball have tolerance and dimensional fits requirement herein) is installed in endoporus, quick change workpiece 1 radially has the groove that steel ball 5 coordinates, stop collar 4 installed surfaces are lozenges structure, on quick change installation main shaft 1, mounting limit overlaps 4 successively, back-moving spring 3 and spacer pin 2, limit the position of stop collar 4 at quick change installation main shaft 1 by spacer pin 2, stop collar 4 is pushed down steel ball 5 all the time, and the back-moving spring distance between stop collar and spacer pin is less than lozenges length in stop collar, be used for the spacing of steel ball, ensure us needed spacing, no matter stop collar is position wherein, several steel balls 5 all cannot drop out.
As shown in Figure 3, now just can pass through mobile stop collar 4, then promote quick change workpiece 6 and make several steel balls 5 be moved to realize the quick change of quick change workpiece.
Quick change frock is mainly used in the quick change of workpiece or fixture, and ensures high accuracy, safe and reliable.Concrete operation step: as shown in Figure 1, when quick change, stop collar 4 is promoted to the right, back-moving spring 3 shrinks, and now just quick change workpiece 6 can be moved to the left, and steel ball 5 just can be pulled to the wedge gap location (gap need be less than diameter of the steel ball) of stop collar 4 and quick change installation main shaft 1 herein, now position is as shown in Figure 3 for steel ball, quick change workpiece just can change like this, decontrols stop collar 4, and back-moving spring 3 resets, next is the replacing of quick change workpiece, same, first stop collar 4 is promoted to the right, back-moving spring 3 shrinks, new quick change workpiece is arranged on to quick change vertically to be installed in main shaft 1 hole, steel ball 5 is pushed, be moved simultaneously, in the time that quick change workpiece 6 arrives bore area, decontrol stop collar 4, back-moving spring 3 resets, steel ball 5 is under the promotion of stop collar 4, along wedge face slide into there are with steel ball quick change workpiece 6 arc grooves that coordinate in (quick change workpiece circular arc groove need to be joined work with steel ball herein), so just, quick change workpiece being locked to quick change installs in main shaft, realize the high accuracy quick change of workpiece.
Utilize the reset of back-moving spring 3, spacer pin 2 spacing, this structure can be for the workpiece of all directions or fixture quick change, comprises vertically horizontal direction etc.Owing to having utilized the characteristic of steel ball, and all need strict fit tolerance between each part, so realized high-precision quick change.
