Description

Technical Field

[0001] This utility model belongs to the field of flange processing technology, and specifically relates to a flange processing clamping device. Background Technology

[0002] A flange is a disc-shaped part used for end-face connection and sealing of pipes, valves, or shaft parts, and usually has annular bolt holes. During machining, it is generally fixed using a three-jaw chuck (turning), an indexing fixture (drilling), or a magnetic chuck (flat surface machining).

[0003] The indexing fixture can precisely control the hole angle. It is usually fixed together with the three-jaw chuck on a horizontal drilling machine. Its structure is relatively complex and cannot be disassembled and used alone. It is also not convenient to use on small vertical drilling machines. The number of bolt holes on the flange is usually an even number such as 4, 8, 12 and 16. Although the size of different flanges will be different, the spacing angle of the holes is generally fixed according to the different number of holes. Therefore, we propose a fixture for drilling and tapping flanges. It can be disassembled and used alone. It is suitable for conventional vertical drilling machines and can adjust the angle for alignment according to different numbers of holes. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a flange processing clamping device that solves the problem of the clamping device for drilling and tapping flanges mentioned in the background. This device can be disassembled and used independently, is suitable for conventional vertical drilling machines, and can adjust the angle for alignment according to different numbers of holes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flange processing clamping device, comprising a base, wherein four sets of insertion holes are provided on the side of the base from top to bottom, each set of insertion holes being equally spaced around the base, and the number of the four sets of insertion holes from top to bottom being 4, 8, 12 and 16 respectively; a four-jaw chuck is rotatably arranged on the upper side of the insertion holes, and a flange is clamped on the upper side of the four-jaw chuck; a first insertion bolt is inserted into the middle of one side of the four-jaw chuck, and a clamping rod is sleeved on the outer side of the first insertion bolt; the side of the clamping rod is longitudinally provided with alignment holes corresponding to the four sets of insertion holes, and a second insertion bolt is inserted into the inner side of the alignment hole, the second insertion bolt passing through the alignment hole and being inserted into the insertion hole.

[0006] The beneficial effects of this utility model are: the device has a simple structure, is easy to operate, and can be disassembled and used separately. It is not integrated with the drilling machine and does not affect other processing of the drilling machine. It can also effectively adjust the angle according to the different drilling requirements of the flange.

[0007] To increase the stability of the base on the vertical drilling machine base plate;

[0008] As a further improvement to the above technical solution: the bottom of the base is fixedly provided with insert blocks at equal intervals.

[0009] The beneficial effects of this improvement are as follows: the bottom of the base is fixedly provided with insert blocks at equal intervals. The base plate of the vertical drilling machine is generally provided with long slots for installing and snapping different fixtures. The insert blocks are provided and snapped into the long slots on the base plate to increase the stability of the base on the base plate of the vertical drilling machine.

[0010] To drain water and metal debris;

[0011] As a further improvement to the above technical solution: the upper side of the four-jaw chuck is an inclined surface that slopes downwards in all directions.

[0012] The beneficial effect of this improvement is that when cooling by spraying water, water and metal debris can be discharged along the inclined surface to the outside of the four-jaw chuck, avoiding the accumulation of water and debris on the four-jaw chuck.

[0013] To quickly remove and replace the four-jaw chuck;

[0014] As a further improvement to the above technical solution: a rotating disk is rotatably connected to the upper side of the base, and a locking block is fixedly provided at the upper center of the rotating disk, and the locking block is inserted and locked into the bottom center of the four-jaw chuck.

[0015] The beneficial effects of this improvement are: the four-jaw chuck can be pulled up directly, and the four-jaw chuck can be pulled out directly from the outside of the clamping block. In actual use, the four-jaw chuck can be set in multiple models, and different models can be used for flanges of a certain diameter within a certain range. When the applicable range does not match, the four-jaw chuck can be quickly removed and replaced directly.

[0016] To reduce frictional resistance;

[0017] As a further improvement to the above technical solution: an annular lubrication groove is provided on the upper side of the base at the lower edge of the rotating disk.

[0018] The beneficial effects of this improvement are: filling the annular lubrication groove with grease to reduce frictional resistance, ensuring smooth rotation of the four-jaw chuck, and reducing operating force.

[0019] To prevent the connector from easily coming loose;

[0020] As a further improvement to the above technical solution: the outer side of the plug is covered with a rubber sleeve.

[0021] The beneficial effects of this improvement are: when the plug-in pin 1 is inserted into the four-jaw chuck, it does not need to be repeatedly pulled out during drilling. The outer side is covered with a rubber sleeve, which can increase the insertion friction between the plug-in pin 1 and the four-jaw chuck, preventing the plug-in pin 1 from easily falling off.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0029] like Figure 1 — Figure 4As shown: A flange processing clamping device includes a base 1. Four sets of insertion holes 2 are formed on the side of the base 1 from top to bottom. Each set of insertion holes 2 is equidistantly arranged around the base. The number of insertion holes 2 in the four sets from top to bottom are 4, 8, 12, and 16 respectively. A four-jaw chuck 3 is rotatably mounted on the upper side of each insertion hole 2. A flange 4 is clamped on the upper side of the four-jaw chuck 3. A plug-in bolt 5 is inserted into the center of one side of the four-jaw chuck 3. A sleeve is fitted on the outer side of the plug-in bolt 5. A locking rod 6 is provided, and alignment holes 7 are longitudinally opened on the side of the locking rod 6 corresponding to four sets of insertion holes 2. Insertion bolts 8 are inserted into the inner side of the alignment holes 7, and the insertion bolts 8 pass through the alignment holes 7 and are inserted into the insertion holes 2. This device has a simple structure, is easy to operate, and can be disassembled and used independently. It is not integrated with the drilling machine and does not affect other processing of the drilling machine. It can also effectively adjust the angle according to the different drilling requirements of the flange 4. Insertion blocks 9 are fixedly arranged at equal intervals at the bottom of the base 1. The base 1 has equidistantly fixed insert blocks 9 at its bottom. The base plate of a vertical drilling machine typically has elongated slots for mounting and engaging different clamps. The insert blocks 9 engage with these slots to increase the stability of the base 1 on the vertical drilling machine base plate. The upper side of the four-jaw chuck 3 is a sloping surface that slopes downwards in all directions. When cooled by water spray, water and metal debris can be discharged along the sloping surface to the outside of the four-jaw chuck 3, preventing water and debris from accumulating on the chuck 3. A rotating disk 10 is rotatably connected to the upper side of the 1. A locking block 11 is fixedly installed at the center of the upper side of the rotating disk 10. The locking block 11 is inserted and locked with the bottom center of the four-jaw chuck 3. The four-jaw chuck 3 can be pulled up directly. The four-jaw chuck 3 can be pulled out directly from the outside of the locking block 11. In actual use, the four-jaw chuck 3 can be set in various models. Different models can be used for flanges 4 with a certain diameter within a certain range. When the applicable range does not match, the four-jaw chuck 3 can be quickly removed and replaced.

[0030] Working principle and usage process of this utility model:

[0031] In use, place the base 1 under the vertical drilling machine, and clamp and fix the flange 4 with the jaws of the four-jaw chuck 3. Align the drill bit of the drilling machine with the upper side of the flange 4 for drilling and tapping. After drilling the first hole, use the first hole as a reference and select the corresponding insertion hole 2 according to the required number of holes. Rotate the four-jaw chuck 3; the chuck 6 rotates with the four-jaw chuck 3. When the alignment hole 7 aligns with the next insertion hole 2, insert the insertion bolt 8 from the alignment hole 7 at the corresponding height and connect it to the corresponding insertion hole 2. This stabilizes the four-jaw chuck 3 relative to the base 1. Continue drilling, repeating the above process until drilling and tapping are complete. This device has a simple structure, is easy to operate, and can be disassembled and used independently, without being integrated with the drilling machine. It does not affect other processing operations of the drilling machine and can effectively adjust the angle according to different drilling requirements of the flange 4. In addition, the base 1 is fixedly provided with insert blocks 9 at equal intervals at its bottom. The base plate of a vertical drilling machine typically has long slots for mounting and engaging different clamps. The insert blocks 9 engage with the long slots on the base plate to increase the stability of the base 1 on the vertical drilling machine base plate. Furthermore, the upper side of the insertion hole 2 is a sloped surface that slopes downwards in all directions. When water is sprayed for cooling, water and metal debris can be discharged along the slope towards the outside of the four-jaw chuck 3, preventing water and debris from accumulating on the four-jaw chuck 3. Additionally, a rotating disk 10 is rotatably connected to the upper side of the base 1. A locking block 11 is fixedly provided at the center of the upper side of the rotating disk 10. The locking block 11 engages with the center of the bottom of the four-jaw chuck 3, allowing the four-jaw chuck 3 to be pulled upwards directly. The four-jaw chuck 3 can be pulled out from the outside of the chuck block 11. In actual use, the four-jaw chuck 3 can be set in various models. Different models can be used for flanges 4 with a certain diameter within a certain range. When the applicable range is not compatible, the four-jaw chuck 3 can be directly and quickly removed for replacement. In addition, an annular lubrication groove is opened on the upper side of the base 1 at the lower edge of the rotating disk 10. Lubricating grease is filled along the annular lubrication groove to reduce frictional resistance, ensure smooth rotation of the four-jaw chuck 3, and reduce operating force. In addition, the outer side of the plug-in 5 is covered with a rubber sleeve. The plug-in 5 is inserted into the four-jaw chuck 3. When drilling, it is not necessary to pull it out repeatedly. The outer rubber sleeve can increase the insertion friction between the plug-in 5 and the four-jaw chuck 3 and prevent the plug-in 5 from easily falling off.
