Description
Technical field
The present invention relates to a kind of frock clamp, a kind of positioning fixture is particularly related to.
Background technology
It is typically necessary during workpiece is cut or processed and workpiece is positioned, is just can guarantee that and add
The accuracy of work, present fixture is usually to be clamped by two gripping blocks after workpiece is placed, such clamping mode
Compare suitable smaller workpiece, if workpiece is than larger and clamp the position of workpiece and be partial to one end, then in work pieces process
During be easy to shift, the quality of influence machining accuracy and product or even can cause personnel to injure.
The content of the invention
In order to solve the above problems, the invention provides a kind of fixture of accurate positioning and suitable big work pieces process.
In order to achieve the above object, the present invention is achieved by the following technical solutions：
The present invention is a kind of positioning fixture, including base, has U-shaped sliding groove in the middle setting of base, the one of base
End is provided with fixed stop, and the other end of base is provided with sliding block, and sliding block is by the limited block with spacing hole
Slided along U-shaped sliding groove, the middle setting in the side of base has the spacing slotted eye of several insertion alignment pins, and alignment pin is by limit
Position slotted eye is inserted into spacing hole and sliding block is carried out spacing, the side of base is provided with extension slideway, in extension slideway
Middle setting has the sliding block slided on extension slideway, and the side of sliding block is provided with cylinder, and spring is passed through in the opposite side of sliding block
It is provided with locating piece.
Further improvement of the present invention is：Two lead columns are inserted with the opposite side of base, in two guiding
Post is inserted into setting a clamping element, and clamping element includes lower gripping block and upper clamping block, and lower gripping block and upper clamping block two ends are distinguished
Connected by shank of bolt and nut.
Further improvement of the present invention is：The face of lower gripping block and upper clamping block contact workpiece is arcwall face or straight
Face.
Further improvement of the present invention is：On base, the left and right sides of U-shaped sliding groove be respectively arranged with several cunnings
Wheel.
Further improvement of the present invention is：Locating piece is arcwall face or flat face with the contact surface of workpiece.
The beneficial effects of the invention are as follows：Fixture accurate positioning of the invention, will not shift during processing, will
Workpiece to be processed is placed between fixed stop and sliding block, is clamped workpiece left and right directions by sliding block, because
Workpiece needs movement, in order to avoid being rubbed in moving process, therefore pulley is increased on base so that workpiece is in cunning
Moved in the presence of wheel, reduce the friction of workpiece, then one end of workpiece is withstood with movable slider by cylinder in one end of workpiece,
Then the other end of workpiece is clamped by clamping element, and such workpiece has obtained workpiece in left and right directions, fore-and-aft direction, so
It is processed again afterwards, it is ensured that the crudy of workpiece.
It is simple structure of the present invention, easy to operate, reasonable in design, the positioning of small workpiece can not only be carried out, but also can enter
Positioning of the row than larger or long workpiece, it is ensured that accurate positioning, does not move, and improves crudy.

Specific embodiment
In order to deepen the understanding of the present invention, the present invention is done below in conjunction with drawings and Examples is further retouched in detail
State, the embodiment is only used for explaining the present invention, protection scope of the present invention is not constituted and is limited.
As Figure 1-4, a kind of positioning fixture of the invention, including base 1, has U-shaped cunning in the middle setting of the base 1
Dynamic groove 2, fixed stop 3 is provided with one end of the base 1, and the other end of the base 1 is provided with sliding block 4, institute
State sliding block 4 to be slided along the U-shaped sliding groove 2 by the limited block 5 with spacing hole 6, workpiece be placed on base 1,
Then sliding block 4 is promoted to be fixed workpiece left and right directions, on the base 1, the left and right two of the U-shaped sliding groove 2
Side is respectively arranged with several pulleys 9, it is preferred that be respectively arranged with two pulleys 9 in the left and right sides of U-shaped sliding groove 2, workpiece is put
Postpone needs to be adjusted on base, in order to avoid the friction between workpiece and base, therefore increased four pulleys 9, facilitate
The movement of workpiece, reduces the friction of workpiece and base, and the middle setting in the side of the base 1 has several insertion alignment pins 8
Spacing slotted eye 7, the alignment pin 8 is inserted into spacing hole 6 by spacing slotted eye 7 and carries out spacing, work to the sliding block 4
Be inserted into alignment pin 8 in spacing slotted eye 7 after fixing rethink and be inserted into being fixed sliding block 4 in spacing hole 6 by part, in institute
The side for stating base 1 is provided with extension slideway 11, has sliding on the extension slideway 11 in the extension middle setting of slideway 11
Dynamic sliding block 12, the side of the sliding block 12 is provided with cylinder 13, and it is fixed to be provided with by spring in the opposite side of the sliding block 12
Position block 13, the locating piece 13 is arcwall face or flat face with the contact surface of workpiece, because workpiece is long after workpiece is placed
The reason for can be moved at two ends in process, therefore workpiece the left and right sides fix after pass through in one end of workpiece
Cylinder drives locating piece 13 to be positioned, and locating piece 13 can be adjusted according to the shape of workpiece, can be an arcwall face
Or a straight face, convenient workpiece, then the other end of workpiece be also carried out fixing to clamp, in the another of the base 1
Side is inserted with two lead columns 10, is inserted into setting a clamping element, the clamping element bag in two lead columns 10
Lower gripping block 14 and upper clamping block 15 are included, the lower gripping block 14 and the two ends of upper clamping block 15 are connected by shank of bolt and nut respectively
Connect, the face of the lower gripping block 14 and the contact workpiece of upper clamping block 15 is arcwall face or flat face, the lower folder of the other end of workpiece
Tight block 14 is slided in two lead columns 10, is enclosed within the outside of workpiece, then enters upper and lower gripping block with nut by the way that bolt is dry
Row is clamped up and down, and the difference according to workpiece can select the shape of upper and lower gripping block and the contact surface of workpiece.
Fixture accurate positioning of the invention, will not be shifted during processing, and workpiece to be processed is placed on
Between fixed stop and sliding block, workpiece left and right directions is clamped by sliding block, because workpiece needs movement, in order to keep away
Exempt to be rubbed in moving process, therefore pulley is increased on base so that workpiece is moved in the presence of pulley, reduce
The friction of workpiece, then one end of workpiece one end of workpiece is withstood with movable slider by cylinder, then the other end of workpiece lead to
Cross clamping element to be clamped, such workpiece has obtained workpiece in left and right directions, fore-and-aft direction, is then processed again, it is ensured that
The crudy of workpiece.
