Abstract
The invention relates to a tool magazine tool clamping device comprising a clamping seat. Lever mechanisms are arranged at the upper end and the lower end of the clamping seat symmetrically, each lever mechanism is fixed on the clamping seat through bolts, a roller is mounted at one end of the lever mechanism, and a clamping seat groove is formed among the rollers and the clamping seat. The tool magazine tool clamping device is characterized in that a spring is mounted on the clamping seat, located between the lever mechanisms and fixedly connected with the lever mechanisms, and the spring and the rollers are located at two ends of the lever mechanism respectively. The spring is arranged between the lever structures, collision force between the clamping seat and a tool is buffered through the spring during tool changing, so that damage to the clamping seat due to tool changing collision is reduced, service life of the clamping seat is prolonged, and frequency of maintenance of the clamping seat is lowered.
Description
Technical field
The present invention relates to technical field of mechanical equipment, be specifically related to a kind of tool magazine cutter holding device.
Background technology
Need during the processing parts of Zuan Gong center to change different cutters from tool magazine, just seem most important as the clamping device of cutter in the tool changing of tool magazine, traditional machining center tool changing device, when tool changing, whole tool magazine is to main axle moving, when the cutter on main shaft enters in the clamping device draw-in groove of tool magazine, main shaft moves up disengaging cutter, and at this moment tool magazine rotates.When the cutter that will change aligns immediately below main shaft, main shaft moves down, and makes cutter enter in spindle taper hole from clamping device draw-in groove, and after clamp-on tool, tool magazine returns original position.When cutter and the clamping device on tool magazine combine with when being separated, due to both hard parts, can collide, while making a noise, also affect the assembly precision of the clamping device on cutter and tool magazine, cutter can be caused for a long time to be separated with the clamping device on tool magazine with the angular deviation of combination large, correct coordinating cannot be carried out with spindle hole, even when tool changing, cutter directly splits away off from clamping device, cannot normal process.Clamping device service life of tool magazine is reduced, and maintenance cost increases, for extremely unfavorable the lathe being engaged in high-efficiency homework.
Chinese patent Authorization Notice No. CN 202964224U, authorized announcement date is the tool change arm that the utility model on June 5th, 2013 discloses a kind of magazine, comprise arm body, described arm body is provided with centre bore, arm body is positioned at the symmetrical configuration of the centre bore left and right sides and identical, be respectively arranged with along the symmetrical cutter pawl chamber of the center line of arm body in former and later two sides of arm body, cutter pawl is connected with cutter pawl in chamber, machine clamping mechanism is provided with in arm body, feature is provided with oil pressure clamp system in arm body, is provided with cutter pawl position-limit mechanism in cutter pawl chamber.
This utility model, by increasing oil pressure clamping mechanism, ensure that the stability of cutter holding, decreases cutter probability.But it does not still solve because cutter and clamping device collide and affect the problem of the assembly precision of clamping device.
Summary of the invention
The tool magazine cutter holding device that the object of the invention is to overcome existing defects and deficiency in prior art, a kind of collision dynamics when can cushion tool changing is provided, extend tool magazine service life, reduce frequency of maintenance.
For realizing above object, technical solution of the present invention is: a kind of tool magazine cutter holding device, comprise holder, the two ends up and down of described holder are symmetrically arranged with leverage, described leverage is bolted on holder, one end of leverage is provided with roller, holder groove is formed between described roller and holder, it is characterized in that: described holder is provided with spring, described spring is between leverage and be fixedly connected with leverage, and spring and roller be not positioned at the two ends of leverage.
Be provided with limited block in described holder, described limited block stretches in holder groove.
Described holder adopts aluminum to be made, and overall one-tenth " L " shape, holder is also provided with reinforcement.
Compared with prior art, the present invention has following beneficial effect:
1, the present invention arranges spring between lever construction, like this when tool changing, the collision dynamics between holder and cutter can be cushioned by spring, thus the damage brought holder is collided in reduction tool changing, extend the service life of holder, reduce the frequency of maintenance of holder.
2, the present invention's mounting limit block in holder, is installed pulley in one end of lever construction, is limited like this, make can better ensure matching requirements when knife rest and main shaft clamping, do not affect machining accuracy when tool changing by pulley and limited block cutter setting frame position.
3, the aluminum that in the present invention, holder adopts, overall in " L " type, and be provided with reinforcing rib structure, can rigidity be improved and reduce deadweight.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of Fig. 1.
In figure: holder 1, leverage 2, roller 3, holder groove 4, spring 5, limited block 6, reinforcement 7, knife rest 8, cam 9, trapezoidal draw-in groove 10, rectangular recess 11.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
See Fig. 1-Fig. 2, a kind of tool magazine cutter holding device, comprise holder 1, the two ends up and down of described holder 1 are symmetrically arranged with leverage 2, described leverage 2 is bolted on holder 1, one end of leverage 2 is provided with roller 3, holder groove 4 is formed between described roller 3 and holder 1, described holder 1 is provided with spring 5, described spring 5 is between leverage 2 and be fixedly connected with leverage 2, and spring 5 and roller 3 be not positioned at the two ends of leverage 2, limited block 6 is provided with in described holder 1, described limited block 6 stretches in holder groove 4.
Described holder 1 adopts aluminum to be made, and overall one-tenth " L " shape, described holder 1 is also provided with reinforcement 7, also reduces its deadweight while being used to provide holder 1 rigidity.
Operation principle of the present invention is: holder 1 cutter setting frame 8 carries out clamping, due to knife rest 8 being provided with boss 9, boss 9 is provided with trapezoidal draw-in groove 10, knife rest 8 enters into the process of holder groove 4 fast, roller 3 contacts with trapezoidal draw-in groove 10 and rolls, the spacing of two rollers 3 can see the string on draw-in groove 10 cross section in echelon, when radial line is increased in the process of maximum (equaling cross section diameter of a circle) by minimum (both just contact-), by leverage 2, spring 5 is compressed, reduce by maximum when string until stop when on knife rest 8, rectangular recess 11 blocks limited block 6, main shaft can unclamp knife rest 8 in the process, spring 5 resilience, discharge a part of power, knife rest 8 can enter into holder groove 4 smoothly, slow down and impact and vibrations.When holder 1 is equipped with knife rest 8, spring 5 remains certain elastic force, makes knife rest 8 have the power pushed in holder groove 4, and is stuck in rectangular recess 11 by limited block 6 and carries out moving-limiting.The space orientation of knife rest 8 can also be realized between roller 3 three of limited block 6 and two symmetries, make can better ensure matching requirements when knife rest 8 and main shaft clamping, do not affect machining accuracy.When carrying out tool changing and unclamping knife rest 8, knife rest 8 is forced to exit from holder groove 4, due to the radial elastic structure that the roller 3 at two ends on holder 1 has with it, knife rest 8 is exited from holder groove 4 smoothly, and produce vibrations and noise very little.
