Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The flange side wall drilling fixture shown in figures 1-5 comprises: the device comprises a base 10, a box body 20, a radial pressure plate assembly 30 and an axial pressing assembly 40;

the box body 20 is fixed on the base 10, and the base 10 is provided with a fixing hole position 11; the top surface and one end surface of the box body 20 are opened to facilitate the placement of the flange;

the radial pressing plate assembly 30 is arranged on one side wall of the box body 20 and comprises a side pressing plate 31 and a pressing plate driving part 32, and the pressing plate driving part 32 drives the side pressing plate 31 to move towards the vertical direction close to or far away from the side wall where the side pressing plate is arranged;

the axial pressing assembly 40 comprises a radial plate 41 and an axial pressing member 42; a radial plate 41 is provided at one end portion of the casing 20, and an axial pressing member 42 is provided on the radial plate 41 and is moved toward or away from the opposite end thereof to press the flange in the axial direction.

When concrete clamp flange, earlier put into box 20 with the flange in, what point out here is mainly, the embodiment of the utility model provides a, for the long neck flange, the lateral wall of flange is cylindric structure, and a certain section of long neck flange is covered, when placing, the one end that will take the lid compresses tightly subassembly 40 setting towards the axial, and at first the lateral wall that compresses tightly subassembly 30 with the long neck flange through radially presss from both sides tightly for the long neck flange can't be at radial movement, then the axial compresses tightly subassembly 40 and compresses tightly the one end that the flange took the end cover, makes the long neck flange also can't move in the axial. Through the cooperation of box 20 and radial clamp plate subassembly 30 and axial compress tightly subassembly 40 for the flange when drilling both ends by fixed, the side is by two tangent clamp tightly in plane, thereby has prevented the rotation and the removal of flange, and fixed when having realized the drilling of flange side has improved the stability when the drilling of flange side, has improved the processing qualification rate of product.

As shown in fig. 2, after the product is processed, in order to facilitate the flange to be removed, a mounting groove 21 is provided on the box 20, the mounting groove 21 is provided at one end of the axial compressing component 40, the mounting groove 21 is provided opposite to the two side walls of the box 20, at least one side of the mounting groove is provided with a fixing hole 211 along the axial direction of the flange, one end of the radial plate 41 is hinged in the fixing hole 211, and the other end of the radial plate is lapped in the mounting groove 21 at the other side of the box 20. After the flange processing finishes, only need to lift up radial plate 41's free end, can be convenient take off the flange, this kind of operating mode sets up through the rotation with radial plate 41, has improved the convenience of product installation with the dismantlement.

In order to make the clamping of the flange end more effective, the height of the mounting groove 21 is half of the height of the case 20. Because the axial compresses tightly subassembly 40 and compresses tightly the flange tip, so compress tightly the point setting in half position department of the box 20 height for the stress point of flange tip is in centre of a circle position department, improves and compresses tightly the effect, prevents the slippage of compressing tightly the point.

As a preferable example of the above embodiment, with continuing reference to fig. 2, the radial plate 41 is provided with a plurality of threaded holes 411 along the length direction thereof, the axial pressing member 42 is a handle passing through the threaded holes 411, and the end of the axial pressing member 42 contacts with the end of the flange to press the flange. Because the radial pressing plate assembly 30 compresses tightly towards one side, and the final positioning positions of the flanges with different sizes are different, in order to improve the compressing applicability of the axial compressing assembly, a plurality of threaded holes are formed in the radial plate 41, so that the position of a compressing point can be conveniently adjusted.

Further, in order to adapt to flanges with different lengths, the radial plates 41 are detachably connected with the mounting grooves 21, and a plurality of groups of the mounting grooves 21 are correspondingly arranged on the box body 20 along the axial direction of the flanges. When the flange is not long enough, the radial plate 41 can be detached and then installed in the installation groove 21 near the flange side, thereby improving the applicability of the fixture.

In the embodiment of the present invention, in order to improve the moving stability of the side pressure plate 31, as shown in fig. 3, a guiding column 311 is further disposed on the side pressure plate 31, the guiding column 311 passes through the sidewall of the box 20, and the guiding column 311 is disposed at least three. In the embodiment of the present invention, the guide posts 311 are provided with four guide posts 411, so that the side pressure plate 31 can move smoothly.

Further, when the machining is completed, in order to facilitate the return of the side platen 31, a compression spring 312 is fitted between the end of the guide post 311 and the side wall of the case 20 to facilitate the return of the side platen 31.

In order to further improve the applicability of the jig, as shown in fig. 4, the end of the box 20 is further provided with a length adjustment plate assembly 50 including an adjustment plate 51, a screw 52 and a fastener 53;

specifically referring to fig. 5, the adjusting plate 51 is disposed inside the box 20, the screw 52 is connected to the adjusting plate 51 and passes through the box 20 to be fixed by a nut, the fastening member 53 is disposed in a threaded hole of the box 20, and the position of the adjusting plate 51 in the box 20 is adjusted by the cooperation of the nut and the fastening member 53. It should be noted here that the fastener 53 is intended to urge the adjusting plate 51 inwardly, and the screw 52 is intended to pull the adjusting plate 51 outwardly, thereby fixing the position of the adjusting plate 51 by the engagement of the two. At the same time, the threaded rod 52 also serves as a guide.

It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
