Abstract
The invention discloses a positioning pin device. The positioning pin device comprises a bottom plate, an elastic positioning pin, an elevating cylinder and an expansion cylinder, wherein an axial guide hole is formed in the elastic positioning pin; a piston rod of the elevating cylinder is fixedly connected with the elastic positioning pin; a piston rod of the expansion cylinder is connected with a positioning push rod; a conical flange which is matched with a conical hole segment on the elastic positioning pin is arranged on the positioning push rod. During working, the elastic positioning pin is inserted into a positioning hole in a workpiece through the elevating cylinder, the positioning push rod is driven to ascend through the expansion cylinder, the outer diameter of the positioning segment of the elastic positioning pin is expanded, and the expanded positioning pin is tightly matched with the workpiece positioning hole, so that assembly clearance errors can be eliminated, and the machining accuracy is increased; moreover, after the completion of machining, the elevating cylinder and the expansion cylinder are used for driving the elastic positioning pin and the positioning push rod to descend respectively, and the positioning pin is separated from the workpiece, so that the interference of the positioning pin to taking of the workpiece can be eliminated, and the production efficiency is increased.
Description
Technical field
The present invention relates to a kind of fixture component, particularly a kind of dowel device.
Background technique
In machining, need to adopt frock position workpiece and clamp.The locating stud that existing frock is commonly used is fixed locating stud, and fixed locating stud is arranged on after in frock, and its position can not change, and locating stud size dimension can not change.
Because locating stud needs to insert in the positioning hole of workpiece, therefore fixed locating stud and workpiece must leave gap between positioning hole, but gap can cause assembly error again, reduce product manufacturing precision.Meanwhile, fixed locating stud can not change because of its position, and when making to get workpiece after machining, locating stud becomes again pickup obstacle, and workpiece can not be taken out fast, reduces manufacturing efficiency.
Summary of the invention
In view of this, the object of this invention is to provide a kind of dowel device, pickup can be caused constant and assembly error can be brought, reduce the problem of machining accuracy to solve existing fixed locating stud.
Dowel device of the present invention, comprises base plate and elastic positioning pin; The positioning section of described elastic positioning pin is along the circumferential direction provided with at least three road shaft orientation opening grooves, in described elastic positioning pin, is provided with axially directed hole, the axially directed hole being positioned at positioning section portion has a round taper hole section;
Described base plate is provided with vertically fixing lift cylinder and top flatulence cylinder, the piston rod of described lift cylinder is fixedly connected with elastic positioning pin, the piston rod of described top account cylinder is connected with localization handspike, described localization handspike and axially directed hole slide up and down cooperation, and localization handspike are provided with the conical lip coordinated with round taper hole section on elastic positioning pin.
Further, described dowel device also comprises the dunnage be fixedly installed on base plate, described dunnage is provided with the lining be slidably matched with elastic positioning pin.
Further, described lift cylinder is connected with elastic positioning pin by connecting plate.
Beneficial effect of the present invention:
Dowel device of the present invention, during work, elastic positioning pin to insert in the positioning hole on workpiece by it by lift cylinder, risen by the swollen air cylinder driven localization handspike in top again, the round taper hole section of localization handspike coordinates with the round taper hole section on elastic positioning pin, the positioning section external diameter of elastic positioning pin is swollen, locating stud after swelling and Workpiece fixing hole closely cooperate, thus can eliminate fit up gap error, improve machining accuracy; And after machining, lift cylinder and top flatulence cylinder drive elastic positioning pin and localization handspike to decline respectively, and locating stud is deviate from from workpiece, thus can eliminate locating stud to the interference fetching workpiece, makes manufacturing efficiency higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of dowel device of the present invention;
Fig. 2 is the plan view of elastic positioning pin.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment dowel device, comprises base plate 1 and elastic positioning pin 2; The positioning section of described elastic positioning pin is along the circumferential direction provided with four road opening slots 3, certainly the quantity of described opening slot also can be other number in more than three Dao Ji tri-roads in different embodiments, be provided with axially directed hole 4 in described elastic positioning pin, the axially directed hole being positioned at positioning section portion has a round taper hole section;
Described base plate is provided with vertically fixing lift cylinder 5 and top flatulence cylinder 6, the piston rod of described lift cylinder is fixedly connected with elastic positioning pin, the piston rod of described top account cylinder is connected with localization handspike 7, described localization handspike and axially directed hole slide up and down cooperation, and localization handspike are provided with the conical lip 8 coordinated with round taper hole section on elastic positioning pin.
During work, elastic positioning pin to insert in the positioning hole on workpiece by the present embodiment dowel device by lift cylinder, risen by the swollen air cylinder driven localization handspike in top again, the round taper hole section of localization handspike coordinates with the round taper hole section on elastic positioning pin, the positioning section external diameter of elastic positioning pin is swollen, locating stud after swelling and Workpiece fixing hole closely cooperate, thus can eliminate fit up gap error, improve machining accuracy; And after machining, lift cylinder and top flatulence cylinder drive elastic positioning pin and localization handspike to decline respectively, and locating stud is deviate from from workpiece, thus can eliminate locating stud to the interference fetching workpiece, makes manufacturing efficiency higher.
As the improvement to the present embodiment, this dowel device also comprises the dunnage 9 be fixedly installed on base plate, described dunnage is provided with the lining 10 be slidably matched with elastic positioning pin; Led by lining 10 pairs of locating studs, the positional accuracy of locating stud can better be ensured, and then improve machining accuracy further.
As the improvement to the present embodiment, described lift cylinder is connected with elastic positioning pin by connecting plate 11, and this improvement can make the structure of elastic positioning pin simpler, connects more convenient.
What finally illustrate is, above embodiment is only in order to illustrate technological scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technological scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
