Abstract
The utility model discloses a kind of novel self-adjusting clamping device, it is characterized by: the clamping device includes chuck (1), three-jaw chuck (2) are provided on the end face of the chuck (1), each three-jaw chuck (2) is both provided with concave groove (3) at the one end in chuck (1) center of circle, it is provided with elastic shaft (4) in the center point of chuck (1), the elastic shaft (4) is connected by spring (5) with chuck (1).This is that one kind is simple in sturcture, ingenious in design, rationally distributed, can allow automatically and carry out centering between product positioning surface and positioning datum, reduces the novel self-adjusting clamping device of human interference factor to greatest extent.
Description
Technical field
The utility model relates to the novel self-adjusting clamping devices of a kind of clamping device, especially Yi Zhongtian.
Background technique
When carrying out secondary operation to bar using numerically controlled lathe, clamping product will be generally carried out using three-jaw chuck, is passed
The three-jaw chuck of system needs operator oneself to hold product and goes for quasi- positioning datum when being put into crude green body, then utilizes three-jaw
Collet clamps one end of bar, and directly starts to process using lathe after clamping；This manually operated mode is easily
There is a situation where product positioning surfaces to deviate fixture positioning datum, it cannot be guaranteed that product quality.Therefore need one kind that can solve now
The certainly method or apparatus of the above problem.
Summary of the invention
The utility model is to propose that a kind of structure is simple to solve above-mentioned deficiency present in the prior art, and design is skilful
It is wonderful, it is rationally distributed, it can allow automatically and carry out centering between product positioning surface and positioning datum, reduce human interference to greatest extent
The novel self-adjusting clamping device of factor.
The technical solution of the utility model is: a kind of novel self-adjusting clamping device, it is characterised in that: the clamping
Device includes chuck 1, three-jaw chuck 2 is provided on the end face of the chuck 1, each three-jaw chuck 2 is close to 1 center of circle of chuck
It is both provided with concave groove 3 at one end, the center point of chuck 1 is provided with elastic shaft 4, the elastic shaft 4 passes through spring 5 and chuck
1 is connected.
The utility model compared with the existing technology, has the advantages that
The novel self-adjusting clamping device of this kind of structure type, simple in sturcture, ingenious in design, rationally distributed, it is directed to
Traditional clamping device (three-jaw chuck) the problems of needs to be positioned manually in use, and designing one kind can be real
The structure of existing adjust automatically, centering when using this clamping device come clamping bar, between product positioning surface and positioning datum
The voluntarily adjusting of equipment is fully relied on, human interference factor can be reduced to greatest extent in this way, reduces position error；It is this fixed
Position mode is compared with the past more flexible, and is suitable for crude green body of different shapes and is accurately positioned, and the scope of application is wider.And it
Manufacture craft it is simple, manufacturing cost is cheap, it can be said that it has a variety of advantages, particularly suitable for pushing away in the art
Wide application, market prospects are very wide.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
Below in conjunction with Detailed description of the invention specific embodiment of the present utility model.A kind of novel self-regulated is self-contained as shown in Figure 1:
Clamp device, including chuck 1 are provided with three-jaw chuck 2 on the end face of chuck 1, and each three-jaw chuck 2 is close to 1 center of circle of chuck
It is both provided with concave groove 3 at one end, the center point of chuck 1 is provided with elastic shaft 4, the elastic shaft 4 passes through spring 5 and chuck
1 is connected.
The course of work of the novel self-adjusting clamping device of the utility model embodiment is as follows: utilizing this clamping device clamping
When workpiece (bar), workpiece is put by operator the center of three-jaw chuck 2 by hand first, one end of workpiece is allowed to withstand on bullet
Property axis 4 end face on, and pressed to the direction where chuck 1, until stopping when spring 5 is contracted to limiting quantity；Then it presses and sets
Standby to start switch, three-jaw chuck 2 inwardly moves, by Workpiece clamping；
After workpiece is clamped, the positioning tool apron on knife rest can be moved to anchor point, and then three-jaw chuck 2 unclamps workpiece,
Under the action of spring 5, elastic shaft 4 will push direction movement of the workpiece towards positioning tool apron, and the other end of workpiece can be with positioning
The end face of tool apron contacts, since spring 5 can apply workpiece so that along its axial power, this power can guarantee always in the process
One end of workpiece and the end face keeping parallelism of elastic shaft 4 are simultaneously in close contact, the end face holding of the other end of workpiece and positioning tool apron
It in parallel and is in close contact, completes the positioning work of workpiece at this time,
It presses equipment again to start switch, three-jaw chuck 2 again by Workpiece clamping, complete, can start to hold by workpiece positioning
Row processing program.
