Drawings
FIG. 1 is a perspective view of the present application;
FIG. 2 is a top view of the present application;
FIG. 3 is a cross-sectional view of the present application;
the reference numbers are as follows: the clamping device comprises a base 1, a first support 2, a first clamping groove 21, a clamping block 3, a second clamping groove 31, a push rod 4, a ball plunger 5, a second support 6, a third clamping groove 61, an X-direction sliding table 71, a Y-direction sliding table 72, a chip groove 8 and an axial limiting block 9.
Detailed Description
The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.
As shown in fig. 1 to 3, a double-ended drilling fixture comprises a base 1, a first bracket 2 is fixed on the base 1, a first engaging groove 21 is formed in the first bracket 2 along an X direction, a Y-direction sliding rail extending along a Y direction is mounted on an upper surface of the base 1, a clamping block 3 is slidably fitted on the Y-direction sliding rail, the clamping block 3 can move along the Y-direction sliding rail, a second engaging groove 31 is formed in the clamping block 3 along the X direction, the second engaging groove 31 can abut against the first engaging groove 21 and is used for jointly engaging a workpiece, in a preferred embodiment, the first engaging groove 21 and the second engaging groove 31 are both semi-cylindrical grooves which can form a complete circular groove when being joined together, and the workpiece is engaged in the circular groove, wherein a through groove extending along the Y direction is formed in the second engaging groove 31, and a push rod 4 is arranged in the through groove, the end of the push rod 4 away from the first engaging groove 21 is connected to a pushing mechanism, which may be a pneumatic cylinder.
The theory of operation of this application is, add man-hour to the work piece in needs, place the work piece in first draw-in groove 21 earlier, then promote fixture block 3, make first draw-in groove 21 splice together with second draw-in groove 31, the two block work piece jointly, can not take place to rotate in the course of working in order to make the centre this moment, support the pressure at second draw-in groove 31 inboard through push rod 4 to the work piece, thereby can make the work piece keep steady, only need install the drilling mechanism coaxial with first draw-in groove 21 in the both sides of work piece X direction this moment, then can keep high axiality drilling.
On above-mentioned basis, because the drilling in-process can produce the piece, these pieces can be filled in the clearance of work piece and draw-in groove, lead to processing to accomplish the back work piece and get the problem of material difficulty, consequently, this application still a bulb plunger 5 is installed to first draw-in groove 21 inboard, and after processing was accomplished, first draw-in groove 21 was kept away from to second draw-in groove 31, and the work piece can be more easily under the promotion of bulb plunger 5 this moment and leave first draw-in groove 21 to accomplish the unloading.
Be provided with second support 6 on the base 1, third draw-in groove 61 has been seted up along the X direction on the second support 6, third draw-in groove 61 with first draw-in groove 21 is coaxial, and this application is through the both ends of first draw-in groove 21 and third draw-in groove 61 difference centre gripping work piece to can further increase the stability of work piece.
On the basis, XXY is installed to slip table 7271 along the side of base 1, second support 6 is connected to slip table 7271 with XXY, XXY is provided with displacement sensor to slip table 7271, displacement sensor is the magnetic grid chi, through being connected second support 6 and XXY to slip table 7271 to can match the work piece of different length, be equipped with displacement sensor and can measure the length of work piece, guarantee that the clamping position is suitable.
In addition, a chip discharge groove 8 is formed in the base 1 below the first clamping groove 21 and the second clamping groove 31, and the chip discharge groove 8 is used for discharging scraps generated after drilling.
In addition, first draw-in groove 21 is kept away from the one end of third draw-in groove 61 and/or third draw-in groove 61 is kept away from the one end of first draw-in groove 21 is provided with axial stopper 9, and axial stopper 9 can fixed mounting be followed at the side of first draw-in groove 21 and/or third draw-in groove 61 to partly stretch into to the draw-in groove, blocks the work piece at axial ascending through axial stopper 9, prevents that the work piece from at drilling in-process axial displacement, and axial stopper 9 keeps the certain distance with first draw-in groove 21 axis in order to guarantee the drilling space.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
