Abstract
A numerally controlled electric chuck of lathe is based on existing 4-jaw chuck. Its screw bolt has the driven gear for driving the jaw. The 4 drive gears engaged with said driven gear via intermediate gears are installed to 4 rotary shafts of 4 motors respectively. Its controller unit with controller and control panel is installed on lathe. Said 4 motors are respectively connected to relative outputs of control circuit.
Description
Technical field
The present invention relates to machine tool component, particularly to the improvement of lathe chuck.
Background technology
On lathe, two kinds of three-jaw and four paws are arranged in order to the chuck of holding workpiece.Scroll chuck is to be provided with three claws on chuck body, each claw has the fluted disc engagement of vortex filament shape teeth groove respectively by the tooth and at the back side, the back side of fluted disc is shaped on the umbrella tooth, with three small bevel gear engagements on the chuck body, rotate arbitrary small bevel gear during use, the driving fluted disc rotates, and three claws is advanced and retreat synchronously, in order to the clamping round piece; Chuck is made up of chuck body, four claws, four screw rods, chuck body is provided with four claws, screw rod is located in the chuck body along radial direction, corresponding with the claw position, each claw is connected with a joggle with each screw rod is corresponding one by one by the tooth at the back side respectively, rotating screw bolt, claw moves in the claw chute of chuck body, four independent mutually, adjustings separately of screw rod, can move four claws arbitrarily, mainly in order to the clamping square workpiece, if be used for the clamping round piece, then need regulate each claw repeatedly, to adjust home position.
Because scroll chuck can't be used for the clamping square workpiece, center of circle trouble was transferred in the school when chuck used, and two kinds of chucks can't be general, caused and used inconvenience.
Summary of the invention
It is a kind of easy to adjust, accurate that the object of the invention is to provide, and can be common to the lathe chuck of square or round piece, uses with convenient.
The present invention adopts Numeric Control Technology, regulate with the motor-driven claw, concrete scheme is: digital control electric chuck for lathe, comprise chuck body, the claw of installing one by one by four claw chutes of chuck body, the claw back side is shaped on the spiral shell tooth, the rear portion correspondence position of chuck body upper clipping claw is respectively equipped with four screw rods, screw rod and the corresponding one by one engagement of claw, screw rod is provided with driven gear, in chuck body, the position corresponding with screw rod is respectively equipped with four motors, is equipped with driving gear on the machine shaft, driving gear, also be provided with idler gear, driving gear between the driven gear, driven gear is connected with a joggle by idler gear.
The control device that includes control device and TIP is installed on the lathe, also be provided with carbon brush configuration on the main shaft of lathe, the line of four motors is electrically connected with the corresponding output end of control circuit respectively by carbon brush configuration, and the input of control circuit is electrically connected with the enter key of TIP.
Motor adopts the stepping reducing motor, and control circuit adopts single chip machine controlling circuit.
Advantage of the present invention is: the driven gear on the screw rod is by idler gear and driving gear engagement, the rotation of stepping reducing motor, rotate by each gear driven screw rod, and then driving claw advance and retreat, with four motors of Single-chip Controlling, reach the purpose of automatic control, have action advantage accurate, easy to adjust, can be used for the clamping of different shape workpiece.
Description of drawings
The invention will be further described with embodiment with reference to the accompanying drawings below.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a three-dimensional view.
Fig. 3 is an electrical schematic diagram.
Mark among the figure: 1 chuck body, 2 motors, 3 driving gears, 4 idler gears, 5 driven gears, 6 screw rods, 7 claws, 8 positioning checkpoints, 9 TIPs, 10 control circuits, 11 power supplys.
The specific embodiment
In conjunction with Fig. 1 and Fig. 2, the digital control electric chuck for lathe of embodiment, the claw 7 that comprises chuck body 1, installs one by one by four claw chutes of chuck body, claw 7 back sides are shaped on the spiral shell tooth, the rear portion correspondence position of chuck body upper clipping claw is respectively equipped with four screw rods 6, screw rod 6 and the corresponding one by one engagement of claw 7, these structures are identical with existing chuck structure.
Screw rod 6 is provided with driven gear 5, in the chuck body, correspondence position at screw rod 6 rear portions is respectively equipped with four motors 2, all be fixed with driving gear 3 on the machine shaft, also be provided with idler gear 4 between driving gear 3, the driven gear 5, driving gear 3, driven gear 5 are connected with a joggle by idler gear 4.
During installation, the control device that includes control device 10 and TIP 9 is installed on the lathe, also be provided with carbon brush configuration on the main shaft of lathe, the line of four motors 2 is electrically connected with the corresponding output end of control circuit 10 respectively by carbon brush configuration, and the input of control circuit 10 is electrically connected with the enter key of TIP 9.Each annexation as shown in Figure 3.
Single chip machine controlling circuit is a known technology, and its operation principle is no longer auspicious to be stated.
During work, according to the setting of TIP 9 enter keies, the corresponding pulse signal of control circuit 10 output, each motor 2 relevant work by four claws of each group gear driven, 7 advance and retreat, clamps, adjusts or loosen operation.
This device can be remembered the position of each claw owing to adopted digital technology, can keep original position after the loading and unloading of workpiece secondary, and is easy to use.
