The utility model is provided with a clamping claw and a connection body which is provided with a center through hole; the rear part of the center through hole matches with and is connected to the drive machine; the front part of the center through hole matches with the connection bolt which connects the drive machine with the connection body; the utility model is also provided with a rotary clamping head surrounding the connection body; the clamping head is provided with a tilting clamping claw groove; the clamping claw is arranged in the clamping claw groove; the front part of the clamping head is provided with a hole through which the clamping claw can extrude out; the clamping claw is connected to the front of the connection body through screw thread. The utility model is of new and simple structure, the connection body can be connected to the drive machine through a screw-thread connection hole and a bolt, so the connection is reliable.
Description
Technical field
The utility model relates to a kind of for example drill chuck of drilling machine or electric drill of plant equipment that is installed in.
Background technology
Present popular drill chuck, the branch that hand fastening drill clutch and keyless drill chuck are arranged, the latter's structure more complicated, be provided with screw rod in its connector, connector is provided with the jaw gathering sill outward, and screw rod links to each other with jaw in the jaw gathering sill, and the advance and retreat of passing through screw rod drive the jaw motion, clamp or the drill bit that gets loose, this drill chuck is complex structure not only, and bodily form length is from great.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of novel drill chuck simple in structure, reliable.For this reason, the utility model is by the following technical solutions: it is provided with jaw and connector, connector is provided with central through hole, the back segment and the driving device of central through hole are connected, and the leading portion of central through hole cooperates with the connecting bolt that is connected driving device and connector, and it also is provided with and is centered around the outer rotatable collet body of connector, described collet body is provided with the jaw groove of inclination, jaw is located in the jaw groove, and the front end of collet body has the hole of stretching out for jaw, and jaw is threaded with the connector front end.Because adopt the technical solution of the utility model, the utility model novel structure is simple, connector can be connected with driving device with bolt by threaded connection hole simultaneously and be connected, and connects reliable.
Description of drawings
The embodiment that Fig. 1 provides for the utility model partly cuts open figure.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the explosive view of Fig. 1.
The specific embodiment
With reference to accompanying drawing.The utility model is provided with jaw 2 and connector 3, connector is provided with central through hole 33, the back segment 331 and the driving device of central through hole are connected, the leading portion 332 of central through hole cooperates with the connecting bolt that is connected driving device and connector, it also is provided with and is centered around the outer rotatable collet body 1 of connector, and described collet body is provided with the jaw groove 11 of inclination, and jaw is located in the jaw groove, the front end of collet body has the hole 12 of stretching out for jaw, and jaw is threaded with the connector front end.
As shown in the figure, the back segment 331 of central through hole is a screwed hole, and the leading portion 332 of central through hole has the conical section 333 that cooperates with the connecting bolt that is connected driving device and connector.
Totally 3 of jaws, corresponding jaw groove 11 also are 3 and evenly are provided with along the collet body circumferencial direction.The connecting thread of jaw and connector front end is a reverse thread.Drawing reference numeral 31 is the tapered thread that the connector front end is connected with jaw.
Also be provided with the back cover 4 that is centered around outside the connector at the collet body rear, collet body is connected with the back cover, and in the present embodiment, collet body is connected with the back external threading, and the rear portion of connector is provided with positioning step 32,321 pairs of collet body axial limitings of the front end face of positioning step.The neighboring, middle part of connector cooperates with the centre bore of collet body 13 location, has simplified the centre bore location structure of collet body and the assembly work of drill chuck.Be provided with ball 5 at the rear end face of positioning step 32 and between afterwards overlapping.
Between the back cover at positioning step and positioning step rear portion, be provided with the round element 6 that periphery has spring leaf 61, spring leaf 61 has self-locking position 62, described back cover inwall is provided with the groove 41 that cooperates with spring leaf self-locking position, the self-locking position 62 of described spring leaf 61 is its lock end, and the lock end of spring leaf 61 outwards protrudes.The described back cover groove that cooperates with the lock end can V-shaped groove.Like this, drill chuck provided by the utility model also has auto-lock function, after jaw clamps drill bit, and no matter forward and backward rotation drill chuck, jaw remains the clamping to drill bit.
Be provided with the fixed cover 7 that can not rotate relative to connector in the outside of back cover, like this, be more convenient for operating drill chuck.Fixed cover 7 and connector are connected so that fixed cover is circumferentially located by opposite side, and axially, fixed cover is matched in clearance by collar 8 axial limitings between back cover and the fixed cover.
