Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of clamping device of the automatic lathe that is used for processing spanner of simple in structure, fixation.
In order to achieve the above object, the technical solution of the utility model is: a kind of clamping device that is used for the automatic lathe of processing spanner, comprise the workpiece installing rack, preceding dog body, back dog body, pull bar, the workpiece installing rack is fixed on the preceding dog body, preceding dog body is fixed with back dog body, back dog body is enclosed within on the pull bar, have the spanner installing hole on the preceding dog body, be provided with chuck around the spanner installing hole, on the dog body, the chuck other end was by bearing pin and rod hinge connection before chuck one end was hinged on by bearing pin, this end of chuck and rod hinge connection is fixed with jaw, jaw is arranged on spanner installing hole front end and is used to clamp spanner, and connecting rod is fixed on the tension dish, and the tension dish is arranged in the dog body of back, the pull bar front end sleeve is in the tension dish, and back end of tie rod is enclosed within the main shaft and connects the tension power set.
As preferably, be fixed with balance weight with workpiece installing rack symmetric position on the described preceding dog body.
As preferably, described tension power set comprise drawing cylinder, drawing cylinder comprises cylinder body, oil cylinder piston bar, the oil cylinder piston bar is by the joint cylinder lever connecting rod, oil cylinder piston bar lower end is fixed with the location-plate that plays motion with one, the location-plate lower end is provided with the inductive probe that sends induced signal according to the position of location-plate, and inductive probe is fixed on the inductive probe installing rack.
As preferably, described chuck is three, and is evenly distributed along preceding dog body.
The clamping device of lathe of the present utility model is by clamping spanner with chuck, chuck is the tension by tensioning mechanism again, spanner is clamped tightly so, guaranteed carrying out smoothly of process operation, simultaneously the front end of chuck is provided with the jaw of band radian, can be close to spanner with its clamping tightly; Opposite side at the workpiece installing rack is provided with balance weight, makes spanner like this in rotation, particularly can keep balance in the bigger spanner of rotating weight, prevents that spanner is thrown out of.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of drawing cylinder of the present utility model.
The specific embodiment
As Fig. 1, shown in 2, clamping device comprises workpiece installing rack 22, preceding dog body 23, back dog body 24, pull bar 32, workpiece installing rack 22 is fixed on the preceding dog body 23, preceding dog body 23 is fixing with back dog body 24, back dog body 24 is enclosed within on the pull bar 32, have spanner installing hole 25 on the preceding dog body 23, be provided with three chucks 26 around the spanner installing hole 25, chuck 26 evenly distributes along preceding dog body 23 circumference, chuck 26 1 ends are hinged on the preceding dog body 23 by bearing pin, chuck 26 other ends are hinged by bearing pin and connecting rod 27, chuck 26 and connecting rod 27 these hinged ends are fixed with jaw 43, and jaw 43 is arranged on spanner installing hole 25 front ends and is used to clamp spanner, and connecting rod 27 is fixed on the tension dish 28; Tension dish 28 is arranged in the back dog body 24, and pull bar 32 front end sleeves are tension dish 28 in and be stuck in the tension dish 28, is provided with bearing 30 in the tension dish 28, is enclosed within on the bearing 30 on the pull bar 32, and back end of tie rod 32 is enclosed within the main shaft 2 and connects strains power set.The tension power set comprise drawing cylinder 34, drawing cylinder 34 comprises cylinder body 36, oil cylinder piston bar 35, oil cylinder piston bar 35 is by joint 47 cylinder lever connecting rods 32, oil cylinder piston bar 35 lower ends are fixed with the location-plate 38 that plays motion with one, location-plate 38 lower ends are provided with the inductive probe 39 that sends induced signal according to the position of location-plate 38, and inductive probe 39 is fixed on the inductive probe installing rack 37.Be fixed with balance weight 33 with workpiece installing rack 22 symmetric positions on the preceding dog body 23.
Spanner is sent on the clamping device, the handle of spanner is placed on the workpiece installing rack 22, spanner is placed into spanner installing hole 25 places, spanner is pushed in the spanner installing hole 25, the oil cylinder piston bar 35 of drawing cylinder 34 drives pull bar 32 and pulls back (position of definition drawing cylinder 34 is the back with respect to chuck 26) then, because pull bar 32 front end sleeves are in tension dish 28 and be stuck in the tension dish 28, pull bar 32 1 pulls back like this, tension dish 28 just pulls back, the connecting rod 27 that is fixed on the tension dish 28 and then pulls back, connecting rod 27 drives an end of hinged with it chuck 26, jaw 43 on chuck 26 these ends just is tightened up, spanner just by jaw 43 be tightened to tightly be close to before 23, three chucks of dog body clamp spanner simultaneously, spanner is just by fixing tightly.After spanner machines, need carry out pusher, at this time drawing cylinder 34 starts, oil cylinder piston bar 35 drives pull bar 32 forward, through a series of with strain opposite transmission process backward, the jaw 43 on the chuck 26 is just released, and the spanner that processes is resigned from office from clamping device.
