Abstract
The utility model provides a rotating device of a turntable style tool magazine, and belongs to the technical field of machines. The rotating device solves the problems that a rotating device of an existing turntable style tool magazine is unstable in rotation and not high in precision. The rotating device of the turntable style tool magazine comprises a gear motor, a support and a tool disc. A cam shaft horizontally penetrates through the lower portion of the support, the gear motor is fixedly connected to the support, a motor shaft of the gear motor drives one end of the cam shaft to rotate, a circle of roller pins which are evenly distributed in the peripheral direction are fixed connected to the tool disc, the cam shaft is fixedly connected with a barrel type cam, and a spiral sliding groove for the roller pins to enter is formed in the peripheral surface of the barrel type cam. The rotating device of the turntable style tool magazine has the advantages of being high in precision, stable in rotation and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of bamboo hat type tool holder, particularly a kind of tumbler of bamboo hat type tool holder.
Background technology
Machining center is the whole processing that complete corresponding operation by the different cutter of automatic replacing in clamped one time, therefore greatly improves working (machining) efficiency.Tool changing device is the important component part of machining center, tool magazine is divided into umbrella shape, cam-type, chain-type etc. by the difference of its structure, wherein bamboo hat type tool holder is the more common a kind of tool changing device of machining center, because its shape picture large bamboo hat is gained the name, its main working process is made up of three steps, and first, tool magazine Traverse Displacement Unit moves to the position that main spindle box can arrive; The second, tool magazine indexing means selects cutter, and by accurately spending, locating, the cutter that next operation is needed is delivered to assigned address; The 3rd, on main shaft, cutter dress cutter is accurately got by automatic loading and unloading mechanism.The feature of bamboo hat type tool holder is that exchanging knives process is simple, volume is little, easy for installation, in vertical machining centre, apply more.
The tumbler of existing bamboo hat type tool holder, the drive plate that comprises circular cutterhead and be fixedly connected with it, on cutterhead circumference, be evenly distributed with some cutter holdings portion, on drive plate, calibration interlaced arrangement has some curved surface grooves and radial slot, drive plate top is provided with cutaway disk, cutaway disk lower surface be equipped with feeling at ease one with drive plate on curved surface groove complementary notch straight pin, on cutaway disk, also bias is provided with the off-centre operation pin that can slide in radial slot.Power set drive cutaway disk to rotate, and when off-centre operation pin slides in radial slot, rotate thereby order about drive plate transmission band movable knife disc, when off-centre operation pin skids off radial slot, breach straight pin enters curved surface groove, now by locked drive plate, cutterhead cannot rotate, thereby completes calibration work.The indexing means of this bamboo hat type tool holder can produce inertia force in the time that rotation round moves, and therefore can affect the precision of tool magazine calibration.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of precision high, rotates the tumbler of bamboo hat type tool holder stably.
The purpose of this utility model can realize by following technical proposal: a kind of tumbler of bamboo hat type tool holder, comprise reducing motor, support and cutterhead, a camshaft is crossed in the bottom of described support, described reducing motor is connected on support and the motor shaft of reducing motor drives camshaft one end to rotate, it is characterized in that, on described cutterhead, be fixed with the circumferential equally distributed needle roller of a circle, on described camshaft, be fixed with barrel shape cam, described barrel shape cam peripheral surface has the screw thread chute entering for needle roller.
The tumbler of this bamboo hat type tool holder, reducing motor drives camshaft to rotate, in the time that the barrel shape cam on camshaft rotates, needle roller is along with the screw thread chute of barrel shape cam rolls, be connected in needle roller on the cutterhead screw thread chute that enters barrel shape cam in turn, thus the rotation with movable knife disc, and the curve on barrel shape cam has the performance of deceleration, can well avoid inertia impact, can make tool magazine rotate stably.
In the tumbler of above-mentioned bamboo hat type tool holder, one end of described needle roller is by nut check on support, and the other end has the roller contacting with cam.
Compared with prior art, the tumbler of this bamboo hat type tool holder utilizes the transmission of cam and needle roller to replace traditional kind of drive, makes the positioning precision of tool magazine and rotatory inertia obtain good control, thereby makes its running accuracy high and steady.
Brief description of the drawings
Fig. 1 is the structural representation of the tumbler of this bamboo hat type tool holder.
Fig. 2 is the sectional structure schematic diagram of the tumbler of this bamboo hat type tool holder.
Fig. 3 is the structural representation of barrel shape cam.
In figure, 1, reducing motor; 2, support; 3, cutterhead; 4, camshaft; 5, needle roller; 6, barrel shape cam; 7, nut; 8, roller.
Detailed description of the invention
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, Figure 2, Figure 3 shows, the tumbler of this bamboo hat type tool holder comprises reducing motor 1, support 2 and cutterhead 3, a camshaft 4 is crossed in the bottom of support 2, reducing motor 1 is connected on support 2 and the motor shaft of reducing motor 1 drives camshaft 4 one end to rotate, on cutterhead 3, be fixed with the circumferential equally distributed needle roller 5 of a circle, on camshaft 4, be fixed with barrel shape cam 6, barrel shape cam 6 peripheral surface have the screw thread chute entering for needle roller 5.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although more used the terms such as reducing motor 1, support 2, cutterhead 3, camshaft 4, needle roller 5, barrel shape cam 6, nut 7, roller 8 herein, do not got rid of the possibility that uses other term.Use these terms to be only used to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
