Abstract
The utility model provides a new type boring clamp head, comprising a clamping claw and a connection body which matches with and is connected to the drive machine, and a rotary clamping head which surrounds the connection body. A tilting clamping claw groove is arranged on the clamping head; the clamping claw is arranged in the clamping claw groove; a screw thread is arranged at the front part of the connection body; the clamping claw comprises the clamping part at the front and a screw thread which is positioned at the rear of the clamping part and matches with the screw thread at the front of the connection body; a stop face which prevents the clamping claw from falling back is arranged on the screw thread at the front part of the connection body. The utility model is of new and simple structure, and the stop face can restrict the position of the falling back of the clamping claw, and prevents the excessive falling back of the clamping claw and prevents the clamping claw from being locked.
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
The jaw of drill chuck relies on the screw thread transmission, moves forward and backward to clamp and the drill bit that gets loose and be driven.Jaw comprises anterior retaining part and is in the flank at retaining part rear, when the operation drill chuck retreats jaw, might make non-threaded the screw thread that damage is threaded with jaw of jaw because of excessive operation, causes jaw to be stuck.
Summary of the invention
It is new-type and can limit simultaneously the new-type drill chuck of jaw overexercise that technical problem to be solved in the utility model provides a kind of structure.For this reason, the utility model is by the following technical solutions: the connector that it is provided with jaw and is connected with driving device, 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, the front end of connector is provided with screw thread, and jaw comprises anterior retaining part and be in the screw thread that is connected with connector front end threaded engagement at retaining part rear that described connector front end screw thread is provided with the retaining face that the restriction jaw retreats.Because adopt the technical solution of the utility model, the utility model novel structure is simple, and the retaining face can play position-limiting action to retreating of jaw, the restriction jaw excessively retreats, and prevents that jaw is stuck.

The specific embodiment
With reference to accompanying drawing.The connector 3 that the utility model is provided with jaw 2 and is connected with driving device, it also is provided with and is centered around the outer rotatable collet body 1 of connector, described collet body is provided with the jaw groove 11 of inclination, jaw is located in the jaw groove, the front end of connector is provided with screw thread 31, jaw comprises anterior retaining part 21 and is in the screw thread 22 that is connected with connector front end threaded engagement at retaining part rear that described connector front end screw thread is provided with the retaining face 310 that the restriction jaw retreats.
Described retaining face 310 can adopt the mode of the front end incomplete thread of removing connector front end screw thread and form, and the shown retaining face of Fig. 2 is the thread profile of formation like this.Show that in Fig. 2 retaining face 310 is the arcwall face transition with the connector surface 311 that is removed incomplete thread, can further play a protective role to jaw and connector front end screw thread like this.
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.
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 outstanding positioning step 32, and positioning step is axially spacing to collet body and back cover.The neighboring, middle part of connector cooperates with the centre bore of collet body 12 location, has simplified the centre bore location structure of collet body and the assembly work of drill chuck.
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.As shown in Figure 1, 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.
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 63 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.
Drawing reference numeral 5 is the ball between round element 6 and back cover.
