The invention relates to the technical field of machine tool clamps, in particular to a mechanical transmission clamp. The mechanical transmission clamp comprises a motor, a reducer connected with the motor and a gear connected with the reducer; the gear is connected with a transmission shaft, a threaded part is arranged in the middle of the transmission shaft, and a lead screw pair nut base is connected to the threaded part in a sliding mode; a first clamping block is fixedly connected to the lead screw pair nut base, and V-shaped clamping grooves are symmetrically formed in the two sides of the clamping block; a second clamping block is connected to the other end of the transmission shaft in a sliding mode, and installation screws are symmetrically installed at the two ends of the second clamping block; a plurality of installation holes used in cooperation with the installation screws are evenly formed in the two sides of the end, in contact with the second clamping block, of the transmission shaft. The workpiece clamping efficiency is improved, and the clamping force is increased.

Description

A kind of machine driving fixture
Technical field
The present invention relates to jig technical field, particularly relate to a kind of machine driving fixture.
Background technology
Current machine vice is widely used on milling machine, generally by manually using spanner rotational lead screw during use, driving movable vise body to move, form stepping up and unclamping workpiece by feed screw nut; But the bothersome effort of manual operation, and the difference of the qualification of operating personnel, the tightness of clamping clamping force is also different.
Summary of the invention
The object of this invention is to provide a kind of raising clamping workpiece efficiency, improve a kind of machine driving fixture of clamping clamping force.
Technical scheme of the present invention is as follows:
A kind of machine driving fixture, comprises motor, the decelerator be connected with motor, the gear be connected with decelerator; Described gear is connected with power transmission shaft, and power transmission shaft central authorities are provided with threaded portion, and this threaded portion is slidably connected with lead screw pair nut seat; Described lead screw pair nut seat is fixedly connected with the first fixture block, and this fixture block bilateral symmetry is provided with " V " clevis groove; The described power transmission shaft other end is slidably connected with the second fixture block, and these the second fixture block two ends are arranged with mounting screw; The both sides, end that described power transmission shaft contacts with the second fixture block be evenly equipped with some with mounting screw with the use of installing hole.
Described lead screw pair nut seat is connected by the collar plate shape pallet be arranged on lead screw pair nut seat with between the first fixture block.Circular lifting surface area is large, has greatly disperseed feed screw nut seat to the active force of the first fixture block, has made fixture block and nut seat be not easy to be worn, have longer service life.
Described second fixture block cross section is truncated cone-shaped, and the large one end of radius is work piece interface.Owing to adopting truncated cone-shaped second fixture block and the large one end of radius and absorption surface, with the contact area of workpiece when increasing clamping work pieces, increase clamping effect.
The lead screw pair that described threaded portion and lead screw pair nut seat are formed adopts ball screw assembly.Ball screw assembly, because sport efficiency is high, it is little to generate heat thus can realize high speed feed motion.
The invention has the beneficial effects as follows: during use, clamp and unclamp the shortest time of workpiece; Appearance and size is little, and install simple, the life-span is long, and without operating noise, use cost is low.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 is motor, and 2 is decelerator, and 3 is gear, and 4 is power transmission shaft, and 5 is threaded portion, and 6 is nut seat, and 7 is the first fixture block, and 8 is " V " clevis groove, and 9 is the second fixture block, and 10 is mounting screw, and 11 is installing hole, and 12 is collar plate shape pallet.
Detailed description of the invention
As shown in Figure 1, a kind of machine driving fixture, comprises motor 1, the decelerator 2 be connected with motor, the gear 3 be connected with decelerator 2; Described gear 3 is connected with power transmission shaft 4, and power transmission shaft 4 central authorities are provided with threaded portion 5, and this threaded portion 5 is slidably connected with lead screw pair nut seat 6; Described lead screw pair nut seat 6 is fixedly connected with the first fixture block 7, and this first fixture block 7 bilateral symmetry is provided with " V " clevis groove 8; Described power transmission shaft 4 other end is slidably connected with the second fixture block 9, and these the second fixture block 9 two ends are arranged with mounting screw 10; The both sides, end that described power transmission shaft 4 contacts with the second fixture block 9 be evenly equipped with some with mounting screw 10 with the use of installing hole 11.
During use, rotary motion through decelerator, passes to axle by band gear from motor; Drive the first fixture block to do linear reciprocating motion by leading screw, and coordinate the second fixture block by Workpiece clamping, when clamping work pieces, the moment of torsion of motor shaft sharply rises, and current strength is corresponding increase also, at this moment electric current relay disable motor.
Wherein be convenient to clamp cylindrical work because the first fixture block bilateral symmetry is provided with " V " clevis groove, and once can clamp two cylindrical works; Again because the second fixture block two ends are arranged with mounting screw, the both sides, end that described power transmission shaft contacts with the second fixture block be evenly equipped with some with mounting screw with the use of installing hole, be connected on power transmission shaft by dismountable for the second fixture block, be convenient to the workpiece that gripping width is long, during use, second fixture block is disassembled, when the first fixture block on power transmission shaft is positioned on the left of workpiece and the contact jaw of power transmission shaft and the second fixture block stretches out on the right side of workpiece, second fixture block is arranged on power transmission shaft and absorption surface, and starter motor drives the first fixture block motion.
Because lead screw pair nut seat and fixture block junction often rub, service time easily weares and teares long afterwards, and for the problems referred to above, preferably, described lead screw pair nut seat is connected by the collar plate shape pallet 12 be arranged on lead screw pair nut seat with between the first fixture block; Because the lifting surface area of circle is large, greatly disperses feed screw nut seat to the active force of the first fixture block, made fixture block and nut seat be not easy to be worn, have longer service life.
Preferably, described second fixture block cross section is truncated cone-shaped, and the large one end of radius and absorption surface.Owing to adopting truncated cone-shaped second fixture block and the large one end of radius and absorption surface, with the contact area of workpiece when increasing clamping work pieces, increase clamping effect.
The lead screw pair that described threaded portion and lead screw pair nut seat are formed adopts ball screw assembly.Ball screw assembly, because sport efficiency is high, it is little to generate heat thus can realize high speed feed motion.
