Detailed Description
The utility model provides a quick location pine clamp mechanism for lathe main shaft which characterized in that: the device comprises an elastic chuck 6, a pull rod 5, a locking device 4, a positioning block 3, a sliding block 2 and a control rod 1, wherein the pull rod 5 penetrates through an inner hole of a main shaft, the elastic chuck 6 is arranged at one end of the pull rod 5, the elastic chuck 6 is positioned at the front end of the main shaft, the locking device 4, the positioning block 3 and the sliding block 2 are respectively arranged at the other end of the pull rod 5, the locking device 4, the positioning block 3 and the sliding block 2 are respectively positioned at the tail end of the main shaft, the positioning block 3 is positioned between the locking device 4 and the sliding block 2, the sliding block 2 is sleeved on the pull rod 5 and positioned at one end close to the locking device 4, the sliding block 2 can move along the pull rod 5, one end of the control rod 1 is connected with the sliding block 2 in a hinged mode, one end, close to the sliding block 2, of the control rod 1 is connected with a machine tool in a hinged mode, one end, close to the positioning block 3, of the sliding block 2 is of an inclined plane structure, the inclined plane is a guide surface, and one end, close to the positioning block 3, is conveniently guided into the positioning block 3, the number of the positioning blocks 3 is 2-4, a claw structure is formed, the positioning blocks 3 are arranged on the pull rod 5 in a hinged mode, one ends, close to the sliding blocks 2, of the positioning blocks 3 are clamping ends, the clamping ends can be clamped on the side walls of the sliding blocks 2, the sliding blocks 2 are grabbed by the positioning blocks 3 at the moment, when the sliding blocks 2 are clamped into gaps between the positioning blocks 3 and the pull rod 5, radial thrust of the positioning blocks 3 is given through the sliding blocks 2, the other ends of the positioning blocks 3 are top ends, and after the positioning blocks 3 are jacked and rotated by the sliding blocks 2, the convex points on the top ends are jacked against the locking devices 4. The other end of the positioning block 3 is of an arc-shaped structure, the highest point of the arc shape is a convex point, the distance from the locking device 4 to the hinged point of the positioning block 3 is smaller than the distance from the convex point to the hinged point of the positioning block 3, the sliding block 2 is moved to the positioning block 3 through the operating rod 1 and clamped, the pull rod 5 is pulled towards the tail end direction of the spindle through pushing of the positioning block 3 to the locking device 4, the pull rod 5 drives the elastic chuck 6 to move towards the tail end direction of the spindle, and the elastic chuck 6 deforms and clamps a workpiece through extrusion of the elastic chuck 6 and the front end of the spindle. After the processing is finished, the operating rod 1 moves the sliding block 2 out of the positioning block 3, the elastic chuck 6 recovers and moves towards the front end direction of the spindle, the elastic chuck 6 pulls the pull rod 5 and the locking device 4 to move towards the front end direction of the spindle, the locking device 4 pushes the positioning block 3 to return, the clamping end of the positioning block 3 is close to the pull rod 5 at the moment, and a gap is formed between the top end of the positioning block 3 and the locking device 4 indirectly. The operating rod 1 is connected with the frame through a pin. The slider 2 is equipped with the mounting groove all around, and control rod 1 passes through the bolt to be connected with the mounting groove, and locating piece 3 sets up on pull rod 5 through two semicircle ring fixings, and two semicircle rings are fixed in on pull rod 5 with the bolt locking respectively. One end of the elastic chuck 6 is fixed on the pull rod 5 in a threaded connection mode. The locking device 4 is of a disc structure, and the locking device 4 is fixed on the pull rod 5 in a threaded connection mode. After the sliding block 2 and the positioning block 3 are clamped in place, the positioning block 3 is clamped at the outer circle of the sliding block 2, the acting force between the sliding block 2 and the positioning block 3 is radial, the positioning block 3 cannot push the sliding block 2 out, but can grasp the sliding block 2, and thus a good clamping effect can be achieved.
The working principle is as follows: the operating rod 1 controls the sliding block 2 to rapidly slide to the positioning block 3, the locking device 4 is locked, meanwhile, the pull rod 5 drives the lower pull collet 6 under the driving of the locking device 4, and the rapid clamping of parts or tools is realized by utilizing the interaction of the taper of the excircle of the collet 6 and the inner hole of the machine tool spindle 7. When the control lever 1 is controlled reversely, the slide block 2 moves reversely, the locking device 4 is released, the pull rod 5 moves reversely at the same time, the elastic chuck 6 is ejected reversely by utilizing the elasticity of the elastic chuck 6, and a part or a cutter is released. Thereby causing the clamping and loosening of the primary part or tool. The pull rod is connected with the locking device 4 and the elastic chuck at the front end of the main shaft through the inner hole of the main shaft, so that the control of quick loosening is realized. The locating piece 3 can be changed according to actual production needs to the adjustment position is in order to adjust the pull rod stroke, control collet's action range, when needing the different parts of clamping or cutter, can be through rotatory mode quick replacement collet at the main shaft front end, reaches general purpose, and then finally realizes that the quick location of lathe main shaft is tight, is relaxed.
