The utility model discloses a three-jaw chuck used for machining synchronous pulleys. The three-jaw chuck comprises a chuck body (1) and three clamping jaws (2) and is characterized in that the pressing face of each clamping jaw (2) is arranged to be an arc-shaped face, the three-jaw chuck further comprises three arc cushions (3), and each arc cushion (3) is fixedly connected to the pressing face of the corresponding clamping jaw (2). The three-jaw chuck is simple in structure, easy to manufacture and beneficial for preventing the synchronous pulleys from damage when the synchronous pulleys are clamped.
Description
Technical field
The utility model relates to synchronous pulley manufacturing equipment field, particularly relates to a kind of synchronous pulley processing scroll chuck.
Background technology
The processing method of prior art synchronous pulley generally adopts first machining hole, the mode of reprocessing tooth, yet, because the radial load that belt wheel need bear in gear hobbing processing is larger, in gear hobbing processing, riveted joint back-up ring hole is large with active force between work holder, easily causes riveted holes distortion, is unfavorable for the installation of belt pulley retainer ring.
Yet Vehicle Processing pore volume is easily realized, gear hobbing difficulty is higher than Vehicle Processing hole.Therefore, in prior art, also there is the technique of first processing tooth reprocessing hole, after gear hobbing completes, first adopt car chuck to clamp the belt wheel flank of tooth, then high accuracy processing endoporus, can guarantee that tooth jumping is within the scope of 0.01-0.03 millimeter.Yet existing lathe three-claw chuck and synchronous pulley contact-making surface are little, the excessive synchronous pulley of clamping force can be because stress surface of concentration be impaired, clamping force is unfavorable to process safety not, because scroll chuck is held the impact of hole working (machining) efficiency larger on the clamping force inconvenience of synchronous pulley.
Utility model content
For in above-mentioned prior art, due to scroll chuck, on the clamping force of synchronous pulley, inconvenient assurance affects larger problem to hole working (machining) efficiency, the utility model provides a kind of synchronous pulley processing scroll chuck.
For the problems referred to above, a kind of synchronous pulley processing that the utility model provides solves problem with scroll chuck by following technical essential: a kind of synchronous pulley processing scroll chuck, comprise chuck body and three claws, the seal face of the claw described in each is all arranged to arc surface, also comprise three arc-shaped pads, the arc-shaped pad described in each is all fixedly connected on the seal face of a claw.
Claw is seal face and the laminating of arc-shaped pad outer surface of arc surface, the inner surface of arc-shaped pad and the laminating of synchronous pulley side, the arc-shaped pad arranging is for transmitting the active force between claw and synchronous pulley, and all become the contact-making surface of cambered surface to be conducive to enlarge active surface, reduce the size of the power in unit are, avoid like this damaging synchronous pulley side when clamping force is larger.
Further technical scheme is:
Arc-shaped pad described in each is near being also provided with a plurality of rack-like grooved in the cambered surface at chuck body center, the trend of the rack-like grooved described in each is all parallel with the center line of chuck body.
A plurality of rack-like grooved that arrange mesh with the tooth bar of belt wheel during for the utility model clamping synchronous pulley; active force between synchronous pulley tooth bar and groove can stop synchronous pulley to rotate with respect to claw like this; do not need larger clamping force synchronous pulley can be fixed on the utility model yet, be conducive to protect synchronous pulley.
Also comprise many connecting bolts, on the claw described in each, be equipped with bolt hole, on the arc-shaped pad described in each, be equipped with blind screw hole, claw all becomes bolt to be connected by connecting bolt with arc-shaped pad.
Claw and arc-shaped pad are arranged to dismountable bolt and are connected, be convenient to change according to the profile of synchronous pulley the arc-shaped pad of coupling, be conducive to improve the utilization rate of chuck body and claw.
Each claw is all fixedly connected with by two connecting bolts with the arc-shaped pad being attached thereto, and two connecting bolts are all positioned at chuck body in the radial direction.
Use two connecting bolt stationary jaws and arc-shaped pad, be intended to the connection arc-shaped pad and the claw that utilize less connecting bolt quantity stable, the setting of connecting bolt direction is intended to be convenient to the dismounting of connecting bolt.
The blind screw hole of the arc-shaped pad setting described in each is a plurality of, and two blind screw holes form one group, and every group of blind screw hole is all positioned at chuck body in the radial direction.
Blind screw hole is divided into groups between two, and every group of radial direction that is all positioned at chuck body, be intended to regulate easily arc-shaped pad with respect to the position of claw, facilitate like this rack-like grooved adjusted on each arc-shaped pad with respect to the position of other arc-shaped pad upper rack shape grooves, be convenient to each arc-shaped pad and all can mesh preferably with synchronous pulley upper rack when clamping synchronous pulley.
The utlity model has following beneficial effect:
1, the utility model is large in the contact area of when work and synchronous pulley side, damages synchronous pulley tooth bar while being conducive to prevent from clamping.
2, the rack-like grooved being arranged on arc-shaped pad has limited relatively rotating between synchronous pulley and arc-shaped pad, be conducive to use less clamping force that synchronous pulley is fixed on the utility model, while further having guaranteed the utility model clamping synchronous pulley, do not damage synchronous pulley.
3, the utility model is simple in structure, and processing and manufacturing is easy.
4, the utility model has been realized synchronous pulley and has been processed the processing technology order of holing after first gear hobbing, and beat this important indicator of gear hobbing in synchronous pulley processing is greatly improved.
