It sets.General tooling clamps to be clamped to be unidirectional, needs to carry out it centering operation after the completion of clamping, can be generated when processing compared with
Big error.
Utility model content
The purpose of the utility model is to provide the high a kind of gear Bidirectional clamping apparatus of Bidirectional clamping, machining accuracy.
Purpose of the utility model is realized as follows: a kind of gear Bidirectional clamping apparatus, including track, it further include setting
Moving to left for side and moves to right movable clamp port at movable clamp port in orbit；The guide rail bottom set there are two elongated be open；It is described to move left pincers
Mouth is provided with symmetrical equal height cushion block with movable clamp port inside is moved to right；Described move to left is connected with cylinder on the left of movable clamp port, the left side
Moved jaw bottom is connected with left L-type spur rack, and the left L-type spur rack is meshed with left gear, the left gear and right tooth
Wheel is meshed, and the right gear is meshed with right L-type spur rack, and the right L-type spur rack fixes company with movable clamp port bottom is moved to right
It connects.
Compared with prior art, the linkage effect having the beneficial effect that due to gear of the utility model, so that two sides
Moved jaw can simultaneously bi-directionally be fed, so that workpiece center during clamping will not move, deviation is smaller.
As a preferred embodiment of the present invention, the tension spring of return is connected on the right side of the right gear.
As the further preferred scheme of the utility model, the left L-type spur rack right side a to left side for right L-type spur rack
The distance of end face, which is greater than, moves to left movable clamp port to the distance for moving to right movable clamp port.
As the further preferred scheme of the utility model, it is described move to left movable clamp port, move to right movable clamp port and track be dovetail
Slot is connected and can be horizontally slipped.
As the further preferred scheme of the utility model, the left L-type spur rack, right L-type spur rack pass through guide rail
Two elongateds are open and can horizontally slip.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the connection schematic diagram of moved jaw and track in the utility model.
Fig. 3 is the utility model guide rail top view.
Wherein, 1 track, 2 move to left movable clamp port, and 3 move to right movable clamp port, 4 equal height cushion blocks, 5 cylinders, 6 left L-type spur racks, 7 left teeth
Wheel, 8 right gears, 9 right L-type spur racks, 10 tension springs, 11 elongateds opening.
Specific embodiment
As shown in Figure 1, a kind of gear Bidirectional clamping apparatus, including track 1, further including that setting is square on track 1 is moved to left
Movable clamp port 2 and move to right movable clamp port 3；1 bottom of guide rail set there are two elongated opening 11；It moves to left movable clamp port 2 and moves to right movable clamp port 3
Inside is provided with symmetrical equal height cushion block 4；The left side for moving to left movable clamp port 2 is connected with cylinder 5, moves to left 2 bottom of movable clamp port and is connected with
Left L-type spur rack 6, left L-type spur rack 6 are meshed with left gear 7, and left gear 7 is meshed with right gear 8, right gear 8 and right L
Type spur rack 9 is meshed, and right L-type spur rack 9 is fixedly connected with 3 bottom of movable clamp port is moved to right.
The tension spring 10 of return is connected on the right side of above-mentioned right gear 8.
The distance of left side of above-mentioned left 6 right side of L-type spur rack to right L-type spur rack 9, which is greater than, moves to left movable clamp port 2 to the right side
The distance of moved jaw 3.
It is above-mentioned that move to left movable clamp port 2, move to right movable clamp port 3 and track 1 be that dovetail groove connect and can horizontally slip.
Above-mentioned left L-type spur rack 6, right L-type spur rack 9 pass through two elongateds opening 11 of guide rail 1 and can horizontally slip.
The working principle of the utility model is described below: when processing, the cylinder 5 on lathe applies active force and is moving left pincers
It on mouth 2, moves to left movable clamp port 2 and moves right along dovetail groove, be driven left gear 7 by left L-type spur rack 6, engaged by gear
Driving force so that right gear 8 operate, drive right L-type spur rack 9, further, move to right movable clamp port 3 and move downward, complete work
The pinching action of part；Cylinder 5 stops working when process finishing, and tension spring 10 is shunk, and similarly moves to left movable clamp port 2 and moves to right movable clamp port 3
It is removed to two sides, completes the release movement of workpiece.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed by the utility model, this
For the technical staff in field according to disclosed technology contents, not needing creative labor can be special to some of which technology
Sign makes some replacements and deformation, these replacements and deformation are within the protection scope of the present utility model.
