Description

Technical Field

[0001] The invention relates to the technical field of flange drilling, in particular to an automatic drilling device for industrial flange mounting holes. Background Art

[0002] Flanges are parts that connect shafts to each other. They are used to connect pipe ends. They are also used as flanges on equipment inlets and outlets, and are used to connect two devices, such as reducer flanges. Flanges are used in pairs. Low-pressure pipelines can use threaded flanges, and pressures above four kilograms use welded flanges. A sealing gasket is added between the two flanges, and then bolted. Therefore, multiple connection holes are set on the flange to fasten the two flanges together with bolts.

[0003] Through searching, Chinese patent announcement number CN220217495U discloses a flange drilling positioning tool, including multiple guide rods, multiple positioning parts and elastic telescopic parts, multiple guide rods are radially distributed, and the inner ends of multiple guide rods are connected to each other; the positioning parts are arranged one by one with the guide rods, the positioning parts are slidably inserted into the guide rods, and positioning holes are provided on the positioning parts, and the positioning parts are used to abut against the outer peripheral surface of the flange; the elastic telescopic parts are sleeved outside the guide rods, and the elastic telescopic parts are configured with a pre-tightening force to make the positioning parts approach the connecting end of the guide rod. The flange drilling positioning tool provided by this technical solution is intended to solve the problem that the flange drilling tool in the prior art is not universal, and each flange of each specification and size needs to be equipped with a corresponding drilling tool, which increases the production cost.

[0004] With respect to the above-mentioned related technologies, it is believed that the following defects exist:

[0005] 1. When the flange is processed, other processing will be performed on the surface of the flange before the mounting holes are opened. In order to ensure the consistency of the flange, the mounting holes need to be opened at the same position and angle of the flange. However, if there are pre-processed holes on the end face or side of the flange, it is difficult to ensure the consistency of the opening position of the mounting holes.

[0006] 2. When processing the mounting holes of the flange, it is sometimes necessary to open the mounting holes on the side due to different installation requirements. However, the traditional punching device cannot complete the end face drilling and peripheral surface drilling at the same station, which requires more operation processes.

[0007] 3. The flanges need to be accurately fixed during installation so that the holes of each flange are in the same position. However, manual accurate fixing is slow and affects production. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The industrial manufacturing flange mounting hole automatic drilling device uses a pre-tightened spring to push the clamping frame to quickly clamp the flange, so that the flange can be initially positioned. The rotation of the flange is blocked by a spring column or an end face ejector during the rotation of the flange, so that the flange can stay in the same position.

[0020] 2. The industrial manufacturing flange installation hole automatic drilling device sets an end face drilling drill and a side face drilling drill at the same work station. The end face drilling drill is rotated to drill holes on the end face of the flange according to needs. The side drilling drill is started and the lifting motor drives the lifting threaded rod, so that the lifting threaded rod drives the lifting shell to adjust the drilling height. The side drilling assembly is pushed out by starting the push-pull telescopic rod to complete the side drilling operation of the flange, so that the side drilling and end face drilling of the flange can be completed at the same work station, which solves the problem that the end face drilling and the peripheral surface drilling of the drilling device cannot be completed at the same work station and requires more operation processes.

[0021] 3. The industrial automatic drilling device for flange mounting holes can make the spring clip frame push the cone nail through the contraction of the two-way telescopic rod, so that the cone nail is extended and pushed by the elastic force of the spring clip frame, so that the cone nail can squeeze the top surface of the flange. When the cone nail contacts the hole on the upper surface of the flange, it is pushed by the spring clip frame to be clamped on the inner side of the hole on the upper surface of the flange. Since the clamping of the flange is achieved by the push of the preloaded spring, the flange will stop rotating when it is blocked. A spring is provided on the inner side of the spring column, and the spring pushes the top cone, so that the rotating flange can be clamped and fixed by the top cone of the spring column, so that the flange can be clamped and fixed at the same angle, which solves the problem of accurate fixation during flange installation and making the holes opened in each flange at the same position.

[0043] A lifting motor 16 is fixedly connected to the upper inner end of the support frame 2, and the end face ejector 159 is composed of a spring frame 1591 and a cone nail 1592.

[0046] When in use, first adjust the position of the adjusting shell 7 by starting the adjusting telescopic rod 6 to determine the position of the angle plate 9 inside the rotating base plate 5, install the flange plate on the surface of the placing table 52 of the rotating base plate 5, so that the flange plate is sleeved on the outside of the clamping frame 133, and the clamping frame 133 is pushed to slide and open on the surface of the pre-tightening rod 131 by the pre-tightening spring 132, so that the flange plate is placed in the processing position;

[0047] By starting the conversion motor 3 to drive the conversion toggle gear 4 to rotate, the conversion toggle gear 4 drives the rotating base plate 5 to rotate, so that the station where the flange is placed rotates continuously, so that the flange can be processed continuously through rotation;

[0048] When the pre-set hole on the surface of the flange is at the end face, the conversion toggle gear 4 is driven to rotate by starting the conversion motor 3, so that the rotating base plate 5 rotates toward the end face brake assembly 15 and moves to the bottom of the end face brake assembly 15, and the transverse movement motor 155 is driven to rotate the transverse movement threaded rod 156, so that the transverse movement frame 157 slides to a suitable position on the end face bracket 154, and the second lifting motor 152 is driven to rotate the second lifting threaded rod 153, so that the end face bracket 154 reaches a suitable height, so that the end face ejector 159 contacts the top surface of the flange, and the two-way telescopic rod 158 is contracted to make the spring frame 1591 push the cone nail 1592, so that the cone nail 1592 extends out and is pushed by the elastic force of the spring frame 1591, so that the cone nail 1592 can squeeze the top surface of the flange, and the corner motor 8 is driven to rotate the corner plate 9, so that the placement The flange on the surface of the clamping frame 133 rotates accordingly. When the cone nail 1592 contacts the hole on the upper surface of the flange, it is pushed by the spring frame 1591 and is clamped on the inner side of the hole on the upper surface of the flange. Since the clamping of the flange using the preload spring 132 is blocked at this time, the flange stops rotating.

[0049] When the pre-set hole on the surface of the flange is on the outer circumference, the conversion toggle gear 4 is driven to rotate by starting the conversion motor 3, so that the rotating base plate 5 rotates toward the side brake assembly 14 and moves to the working position of the side brake assembly 14, and the first lifting motor 142 is driven to rotate the first lifting threaded rod 143 to make the side sliding shell 145 reach the appropriate position, and the longitudinal motor 148 is driven to rotate the longitudinal threaded rod 149 to make the spring column 1410 reach the exact position of the hole, and the side sliding block 147 is pushed to move by the electric telescopic rod 146 to make the spring column 1410 approach and squeeze the surface of the flange, and the angle motor 8 is driven to rotate the angle plate 9 to make the flange follow the rotation, and when it rotates to the hole on the outer circumference of the flange, the top cone on the surface of the spring column 1410 clamps the flange to stop rotating, and the linkage motor 10 is started again to fix the flange position to ensure the uniformity of the angle position of the flange to facilitate the subsequent opening of the installation hole;

[0050] After the flange is fixed, the side brake assembly 14 or the end brake assembly 15 is moved away from the flange, and the fixed flange is driven by the conversion motor 3 to reach the position of the support frame 2. The lateral adjustment motor 192 is started as needed to drive the lateral adjustment threaded rod 193 to rotate, so that the position of the lateral transfer block 194 is adjusted, and the end face drilling drill 195 is started and the lifting threaded rod 17 is driven by the lifting motor 16, so that the end face drilling drill 195 can drill holes in the end face of the flange. When the outer peripheral surface needs to be drilled, the side drilling drill 212 is first started, and the lifting threaded rod 17 is driven by the lifting motor 16, so that the lifting threaded rod 17 drives the lifting shell 18 to adjust the drilling height, and the side drilling assembly 21 is pushed out by starting the push-pull telescopic rod 20 to complete the side drilling operation of the flange.
