Description

Technical Field

[0001] This utility model relates to the technical field of flange production and processing equipment, and in particular to a flange production and processing equipment with automatic centering function. Background Technology

[0002] Flanges are a common connecting component in mechanical and piping engineering. They are typically circular disc-shaped structures with holes around their perimeter, used to connect two pieces of equipment or pipes together with bolts. The main function of a flange is to provide a sealed connection while facilitating disassembly and maintenance. The perforated flanges allow for easy disassembly and repair, enabling quick disassembly of the flange connection when equipment needs maintenance or parts replacement, saving time and labor costs. Multi-axis drilling machines are a commonly used flange drilling equipment. However, because multi-axis drilling machines generate a lot of heat when drilling flanges, especially when the metal material is hard, workers use coolant to cool the drilling area of ​​the flange to prevent overheating that could cause tool wear and material deformation.

[0003] The patent "CN220554904U" discloses a "flange drilling device" that uses a support base to tighten and fix the inner ring of the flange to complete the flange fixing work. On the one hand, the flange fixing work can be completed by the cooperation of the tie rod and the inner ring of the flange, reducing the space requirements for the support base layout. On the other hand, when the flange is fixed, the center of the flange can always be aligned with the rotation axis of the turntable, eliminating the need for center positioning work, so that the drilling work of the flange can be carried out quickly after fixing, ensuring drilling efficiency. Because existing flanges require manual positioning before drilling, the alignment cycle is long and the alignment accuracy is lacking. At the same time, the coolant used for cooling is directly accumulated on the base, causing inconvenience for subsequent equipment cleaning. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems by proposing a flange production and processing equipment with automatic centering function. It improves the existing flanges, which require manual positioning before drilling, resulting in a long alignment cycle and insufficient alignment accuracy. At the same time, the coolant used for cooling accumulates directly on the base, causing inconvenience for subsequent equipment maintenance and cleaning.

[0005] A flange production and processing equipment with automatic centering function includes a support base body and a multi-axis drilling machine body: the top outer wall of the support base body is provided with the multi-axis drilling machine body, the upper part of the support base body is provided with a centering positioning mechanism, the side of the centering positioning mechanism is provided with a portable replacement mechanism, and the lower part of the support base body is provided with an auxiliary collection mechanism.

[0006] The centering positioning mechanism includes a positioning support, a drive cylinder, and an auxiliary mounting plate. The positioning support is symmetrically arranged on the top outer wall of the support base body. The drive cylinder is arranged on the side outer wall of the positioning support near the multi-axis drilling machine body. The output end of the drive cylinder is connected to the side outer wall of the auxiliary mounting plate.

[0007] Preferably, the auxiliary mounting plate has a supporting back plate on the outer side wall away from the drive cylinder, and the supporting back plate has a clamping block on the outer side wall away from the auxiliary mounting plate. A friction pad is embedded in the outer side wall of the clamping block, and both the clamping block and the friction pad are configured as semi-circular ring structures.

[0008] Preferably, the portable replacement mechanism includes limiting support bars, and the supporting back plate is symmetrically provided with limiting support bars on the outer side wall near the auxiliary mounting plate. The outer side wall of the auxiliary mounting plate is provided with two sets of limiting grooves, and the limiting support bars and limiting grooves are slidably installed.

[0009] Preferably, the limiting support bar has symmetrical positioning blocks on both outer walls at the top position, and the auxiliary mounting plate has a corresponding positioning slot on the top outer wall at the limiting slide groove position. The positioning blocks and the positioning slots are engaged and installed together.

[0010] Preferably, the top outer wall of the positioning block has a first threaded groove, and the top outer wall of the auxiliary mounting plate located at the positioning groove has a corresponding second threaded groove. The first and second threaded grooves are threadedly installed with the fastening bolt.

[0011] Preferably, the auxiliary collection mechanism includes an overflow trough and a storage tank. The top outer wall of the support base body is provided with two sets of overflow troughs, and the inner side wall of the overflow trough is connected with a protective filter plate. The bottom outer wall of the support base body is provided with a storage tank, and the top outer wall of the storage tank located at the overflow trough position is provided with a through groove.

[0012] Preferably, a drain pipe is installed on the outer side wall of the bottom of the liquid storage tank, and a control valve is provided on the outside of the drain pipe.

[0013] The beneficial effects of the utility model are:

[0014] 1. This flange production and processing equipment with automatic centering function uses a mechanism to make the two sets of semi-annular clamping blocks detachable. This allows the equipment to select the appropriate size clamping block according to the diameter of the flange to be processed before use. Furthermore, the two sets of clamping blocks can be combined into a complete ring. During the clamping process, the centering of the flange can be automatically completed without secondary adjustment. This ensures the stability of the flange's positioning and provides a guarantee for the accuracy of the subsequent flange drilling process. The overall structure is ingeniously designed and has good practical effect.

[0015] 2. When using this flange production and processing equipment with automatic centering function, since the coolant overflow is generally distributed on both sides of the flange, this device has an overflow channel designed through the location on the base where coolant is prone to accumulate. This allows most of the coolant on the base to be collected directly into the storage tank through the overflow channel. This reduces the amount of coolant accumulation on the workbench and facilitates the subsequent cleaning and maintenance of the equipment. In addition, the design of collecting coolant increases the overall weight of the device, which at the same time provides a reinforcing support effect for the overall placement stability of the device. The overall structural design is simple and has good practical effect. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] When implementing: Figure 1-5 As shown, a flange production and processing equipment with automatic centering function includes a support base body 1 and a multi-axis drilling machine body 2: the top outer wall of the support base body 1 is provided with the multi-axis drilling machine body 2, the upper part of the support base body 1 is provided with a centering positioning mechanism 3, the side of the centering positioning mechanism 3 is provided with a portable replacement mechanism 4, and the lower part of the support base body 1 is provided with an auxiliary collection mechanism 5.

[0024] The centering positioning mechanism 3 includes a positioning support 31, a drive cylinder 32, an auxiliary mounting plate 33, a support back plate 34, a clamping block 35, and a friction pad 36. The positioning support 31 is symmetrically arranged on the top outer wall of the support base body 1. The drive cylinder 32 is arranged on the side outer wall of the positioning support 31 near the position of the multi-axis drilling machine body 2. The output end of the drive cylinder 32 is connected to the side outer wall of the auxiliary mounting plate 33. The support back plate 34 is arranged on the side outer wall of the auxiliary mounting plate 33 away from the position of the drive cylinder 32. The clamping block 35 is arranged on the side outer wall of the support back plate 34 away from the position of the auxiliary mounting plate 33. The friction pad 36 is embedded in the side outer wall of the clamping block 35.

[0025] When it is necessary to center the flange for stable drilling, simply place the flange on top of the support base 1 after adjusting it to the appropriate position, and then simultaneously activate the two drive cylinders 32. The positioning support 31 here provides positioning and support for the drive cylinders 32. When the drive cylinders 32 are activated, their output ends automatically extend and move the auxiliary mounting plate 33. The movement of the auxiliary mounting plate 33 then moves the support back plate 34, which in turn moves the clamping blocks 35. As the two sets of clamping blocks 35 move in opposite directions, the flange to be processed will automatically be pressed against the middle of the two sets of clamping blocks 35. The friction pad 36 here increases the contact friction between the device and the outer wall of the flange, thereby strengthening the flange's contact and positioning effect. After clamping, simply close the drive cylinders 32. Note that the drive cylinders 32 have a self-locking function; after closing, the clamping blocks 35 will remain in the same position after movement.

[0026] Both the clamping block 35 and the friction pad 36 are designed as semi-circular rings; this design allows the overall shape of the clamping block 35 and the friction pad 36 to be closer to the outer wall shape of the flange, thereby achieving a better clamping effect.

[0027] The portable replacement mechanism 4 includes a limiting support bar 41. The supporting back plate 34 is symmetrically provided with limiting support bars 41 on the outer side wall near the auxiliary mounting plate 33. The outer side wall of the auxiliary mounting plate 33 is provided with two sets of limiting grooves. The limiting support bar 41 and the limiting groove are slidably installed. The two outer sides of the limiting support bar 41 at the top position are symmetrically provided with positioning blocks 42. The top outer wall of the auxiliary mounting plate 33 at the position of the limiting groove is provided with a positioning slot 43. The positioning blocks 42 and the positioning slot 43 are engaged. The top outer wall of the positioning blocks 42 is provided with a first threaded groove 44. The top outer wall of the auxiliary mounting plate 33 at the position of the positioning slot 43 is provided with a second threaded groove 45. The first threaded groove 44 and the second threaded groove 45 are threadedly installed with the fastening bolt 46.

[0028] When it is necessary to select a suitable size clamping block 35 according to the size of the flange to be processed and install the new clamping block 35 into the device, the old clamping block 35 must first be removed from the device. When removing it, simply unscrew the fastening bolt 46 from the inside of the first threaded groove 44, and then the positioning block 42 changes from the state to the movable state. Then, simply lift the clamping block 35 upward in the vertical direction to remove it from the device. When installing the new clamping block 35, first, adjust the clamping block 35 to a suitable position and then push the limiting support bar 41 on the side of the support back plate 34 from top to bottom into the corresponding limiting slide groove. When the limiting support bar 41 moves to the bottom end of the limiting slide groove, the positioning block 42 just fits into the bottom end of the positioning slot 43. At the same time, the first threaded groove 44 and the second threaded groove 45 are in a corresponding overlapping state. Then, use the fastening bolt 46 to pass through the first threaded groove 44 and screw it to the bottom end of the second threaded groove 45 to complete the replacement installation of the clamping block 35.

[0029] The auxiliary collection mechanism 5 includes an overflow trough 51 and a storage tank 52. Two overflow troughs 51 are opened through the top outer wall of the support base body 1, and a protective filter plate is connected to the inner side wall of the overflow trough 51. A storage tank 52 is provided on the bottom outer wall of the support base body 1, and a through groove is opened through the top outer wall of the storage tank 52 at the position of the overflow trough 51. A drain pipe 53 is installed through the outer side wall of the storage tank 52 at the bottom position, and a control valve 54 is provided on the outside of the drain pipe 53.

[0030] Because the multi-axis drilling machine body 2 generates a lot of heat when drilling the flange, especially when the metal material is hard, the heat generation phenomenon is more significant. Therefore, the operator will use coolant to cool down the drilling position of the flange to prevent tool wear and material deformation caused by overheating. When the operator uses coolant to cool the flange, most of the coolant overflows and is distributed on both sides of the flange. At this time, most of the coolant overflowing on the table will be automatically collected into the storage tank 52 through the overflow groove 51. When it is necessary to drain the coolant collected in the storage tank 52, simply open the control valve 54. After the control valve 54 is opened, the coolant in the storage tank 52 will be automatically drained to the outside of the device through the drain pipe 53. The protective filter plate here fills the gap of the overflow groove 51, ensuring the flatness of the support base body 1 on the table, and also ensuring the normal flow of coolant.

[0031] When using this utility model, firstly, a clamping block 35 of appropriate size needs to be selected according to the size of the flange to be processed. When installing the new clamping block 35 into the device, the old clamping block 35 needs to be removed from the device. When removing it, the fastening bolt 46 is unscrewed from the inside of the first threaded groove 44, and the positioning block 42 changes from the state to the movable state. Then, the clamping block 35 can be lifted upwards in the vertical direction to remove it from the device. When installing the new clamping block 35, the clamping block 35 needs to be adjusted to a suitable position first, and then the limiting support bar 41 on the side of the supporting back plate 34 is pushed from top to bottom into the corresponding limiting groove. When the limiting support bar 41 moves to the bottom end of the limiting groove, the positioning block 42 is just inserted into the bottom end of the positioning groove 43. At the same time, the first threaded groove 44 and the second threaded groove 45 are in a corresponding overlapping state. Then, the fastening bolt 46 is passed through the first threaded groove 44 and screwed to the bottom end of the second threaded groove 45 to complete the replacement installation of the clamping block 35.

[0032] When it is necessary to center the flange for stable drilling, simply place the flange on top of the support base body 1 after adjusting it to the appropriate position, and then simultaneously activate the two drive cylinders 32. The positioning support 31 here provides positioning and support for the drive cylinders 32. When the drive cylinders 32 are activated, their output ends automatically extend and drive the auxiliary mounting plate 33 to move. The movement of the auxiliary mounting plate 33 then drives the support back plate 34 to move, which in turn drives the clamping block 35 to move. As the two sets of clamping blocks 35 move in opposite directions, the flange to be processed will automatically be pressed against the middle position of the two sets of clamping blocks 35. The friction pad 36 here strengthens the contact positioning effect of the flange by increasing the contact friction between the device and the outer wall of the flange. After clamping, the drive cylinders 32 can be closed directly. It should be noted that the drive cylinders 32 have a self-locking function, and the clamping blocks 35 can remain in the same position after being moved even after being closed.

[0033] Because the multi-axis drilling machine body 2 generates a lot of heat when drilling the flange, especially when the metal material is hard, the heat generation phenomenon is more significant. Therefore, the operator will use coolant to cool down the drilling position of the flange to prevent tool wear and material deformation caused by overheating. When the operator uses coolant to cool the flange, most of the coolant overflows and is distributed on both sides of the flange. At this time, most of the coolant overflowing on the table will be automatically collected into the storage tank 52 through the overflow groove 51. When it is necessary to drain the coolant collected in the storage tank 52, simply open the control valve 54. After the control valve 54 is opened, the coolant in the storage tank 52 will be automatically drained to the outside of the device through the drain pipe 53.

[0034] The aforementioned drive cylinder 32 requires a PLC (Programmable Logic Controller) to control its opening and closing actions in order to ensure that the two sets of drive cylinders 32 start synchronously and that the two sets of clamping blocks 35 have a centered contact effect with the flange. Using a PLC (Programmable Logic Controller) to control the drive cylinder 32 is existing technology, so it is not described in detail in this article.

[0035] It should be noted here that the drive cylinder 32 is connected to the pneumatic components to control its drive in accordance with existing operating techniques. At the same time, the multi-axis drilling machine body 2 is driven to drill holes in the flange in accordance with existing operating technical standards. No modifications have been made, and it is a conventional operating technique. Therefore, it will not be described in detail here.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
