Description

Technical Field

[0001] This utility model relates to the field of pipe construction equipment technology, and in particular to chucks and processing equipment. Background Technology

[0002] Oil and gas pipeline stations are an important part of oil and gas pipeline systems. They can be divided into in-station process pipelines and external connection pipelines. In-station process pipelines are mainly responsible for the transportation and distribution of oil and gas between various equipment within the station. External connection pipelines are used to connect different stations or to external oil and gas sources and users. Station pipeline flanges are important components used to connect oil and gas pipelines.

[0003] When welding oil and gas pipelines and flanges, workers need to constantly adjust their positions. If the welder cannot adjust the position in a timely and accurate manner, it will be difficult to ensure that the welding angle and parameters meet the requirements, which will lead to welding defects. Utility Model Content

[0004] This utility model provides a chuck and processing equipment to enable the rotation of the pipeline itself, avoiding the problem of workers constantly adjusting their own position or the position and angle of the pipeline during welding. To achieve the above objective, the technical solution adopted by this utility model is as follows:

[0005] In a first aspect, this application provides a chuck, including a support base, a connecting sleeve, a clamping assembly, and a driving assembly. The support base has a receiving hole extending along a first direction; the connecting sleeve is at least partially received within the receiving hole, the axial direction of the connecting sleeve is aligned with the first direction, the connecting sleeve is slidably connected to the support base, and the connecting sleeve includes a first open end face and a second open end face along the first direction; the clamping assembly is connected to the first open end face and is used to clamp a component to be clamped within the connecting sleeve; the driving assembly is connected to the second open end face and is used to drive the connecting sleeve to rotate.

[0006] According to the aforementioned technical means, the support base is provided with a receiving hole extending along the first direction to accommodate and place the pipe. One end of the connecting sleeve is connected to the clamping assembly, and the other end is connected to the drive assembly, facilitating installation and disassembly. The clamping assembly is used to clamp the pipe, and the drive assembly drives the pipe to rotate during the clamping process, facilitating omnidirectional welding of the flange and the pipe end, and avoiding the need for workers to constantly adjust their own position or the position and angle of the pipe during welding work.

[0007] In one possible implementation, the clamping assembly includes a fixing member and a clamping member. The fixing member is fixedly connected to a first open end face and has a first clearance hole that corresponds to the opening of the connecting sleeve. The clamping member is located on the side of the fixing member opposite to the first open end face and can move toward or away from the first clearance hole to lock or release the object to be clamped. Along the circumference of the first clearance hole, the fixing member and the clamping member are fixed relative to each other.

[0008] According to the above technical means, the clamping component is used to hold the pipe, and the fixing component is used to receive the power from the connecting sleeve. The connecting sleeve can drive the fixing component and the clamping component to rotate simultaneously. Among them, the fixing component provides installation space for the clamping component.

[0009] In one possible implementation, the clamping assembly further includes an adjusting rod rotatably connected to the side surface of the fixing member opposite to the first opening end face; the number of clamping members is multiple, including a first clamping member and a second clamping member disposed opposite to each other, the first clamping member and the second clamping member are both sleeved on the adjusting rod and threadedly engaged with the adjusting rod; the first clamping member and the second clamping member are threaded in opposite directions to the adjusting rod.

[0010] According to the above-mentioned technical means, the first clamping member and the second clamping member are both sleeved on the adjusting rod and threadedly engaged with the adjusting rod. The adjusting rod is used to control the relative or disengaged movement of the first clamping member and the second clamping member, thereby clamping or releasing the pipeline. The first clamping member and the second clamping member are threaded in opposite directions with the adjusting rod. When the adjusting rod is rotated clockwise, the two clamping members move towards the center simultaneously, achieving rapid clamping; when rotated counterclockwise, they are released simultaneously, without the need to operate the clamps on both sides separately.

[0011] In one possible implementation, the adjusting rod is a two-way lead screw.

[0012] Based on the aforementioned technical means, the thread structure of the bidirectional lead screw is a left-right symmetrical design, with both left-hand and right-hand threads present simultaneously. When the lead screw rotates, it achieves bidirectional drive for the first and second clamping components.

[0013] In one possible implementation, the first clamping member has a first clamping portion on the side facing the second clamping member, and the second clamping member has a second clamping portion on the side facing the first clamping member. The first clamping portion and the second clamping portion are arranged opposite each other in the radial direction of the receiving hole.

[0014] According to the above technical means, the first clamping part provided on one side of the first clamping member is opposite to the second clamping part provided on one side of the second clamping member, so as to ensure the clamping and fixing of the pipeline.

[0015] In one possible implementation, the clamping assembly further includes a guide rod disposed on the side surface of the fixing member opposite to the first opening end face. The guide rod and the adjusting rod are arranged radially opposite to each other along the receiving hole. The first clamping member and the second clamping member are both sleeved on the guide rod and slidably connected to the guide rod.

[0016] According to the above technical means, the first clamping member and the second clamping member have through holes at the ends opposite to the mounting adjustment rod for mounting the guide rod. The first clamping member and the second clamping member are both sleeved on the guide rod and slidably connected to the guide rod. The guide rod is used to constrain the movement direction of the first clamping member and the second clamping member to ensure precise linear movement.

[0017] In one possible implementation, the drive assembly includes a transmission element and a drive element, the transmission element being fixedly connected to the second open end face; the drive element being geared to the transmission element.

[0018] Based on the above technical means, the driving component, as the power source, transmits its own power to the transmission component. The driving component and the transmission component are connected by gears, which can realize the precise conversion of the driving component speed to the transmission component speed.

[0019] In one possible implementation, the transmission component includes a second clearance hole that corresponds to the opening of the connecting sleeve, and the outer peripheral surface of the transmission component is provided with an external gear that drives the gear of the driving component.

[0020] According to the above technical means, the second clearance hole corresponds to the opening of the connecting sleeve, and the outer peripheral surface of the transmission component is provided with an external gear that drives the gear of the driving component. The transmission component drives the connecting sleeve to rotate, so as to realize the rotation of the fixed pipe, thereby facilitating the welding of the flange and the pipe.

[0021] In one possible implementation, the wall of the receiving hole is provided with a rotating groove, at least a portion of the connecting sleeve is received in the rotating groove, and at least a portion of the connecting sleeve is rotatably connected to the rotating groove.

[0022] According to the above technical means, the connecting sleeve is at least partially engaged in the rotating groove, which allows the connecting sleeve to rotate flexibly at different angles while maintaining axial stability.

[0023] Secondly, a processing apparatus is also provided, which includes at least one or more chucks as described in the first aspect, wherein the axial direction of the multiple through holes corresponding to the multiple chucks is consistent.

[0024] Since the processing equipment provided in this application includes a chuck as described in any of the above embodiments, both can solve the same technical problem and achieve the same effect.

[0025] The beneficial effects of this utility model are:

[0026] 1. After the clamping component of the device fixes the oil and gas pipeline, the drive component drives the oil and gas pipeline and flange to rotate, allowing the workers to perform welding work on the oil and gas pipeline and flange from all angles. This can effectively prevent welding defects and ensure the accuracy of the welding work.

[0027] 2. The clamping components of this device can be adapted to fix oil and gas pipelines of different sizes, ensuring the stability of the welding work. Attached Figure Description

Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0037] In some embodiments, see Figure 1 This application provides a processing device, which includes a chuck. In this embodiment, the chuck is used to clamp the oil and gas pipeline at the station and weld the flange to the end of the pipeline in all directions, eliminating the need for workers to constantly adjust their own position or the position and angle of the pipeline.

[0038] Please see Figure 1 and combined Figure 4 and Figure 3 This application provides a chuck, including a support base 100, a connecting sleeve 200, a clamping assembly 300, and a driving assembly 400. The support base 100 has a receiving hole 500 extending along a first direction; the connecting sleeve 200 is at least partially received within the receiving hole 500, the axial direction of the connecting sleeve 200 is consistent with the first direction, the connecting sleeve 200 is slidably connected to the support base 100, and the connecting sleeve 200 includes a first open end face and a second open end face along the first direction; the clamping assembly 300 is connected to the first open end face and is used to clamp a component to be clamped within the connecting sleeve 200; the driving assembly 400 is connected to the second open end face and is used to drive the connecting sleeve 200 to rotate.

[0039] Based on this, the support base 100 is provided with a receiving hole 500 extending in a first direction to accommodate a pipe. A connecting sleeve 200 is engaged within the receiving hole 500, at least partially contained within it, and rotatable within it. The connecting sleeve 200 is slidably connected to the support base 100. One end of the connecting sleeve 200 is connected to the clamping assembly 300, and the other end is connected to the driving assembly 400, facilitating installation and disassembly. The clamping assembly 300 clamps and fixes the pipe, while the driving assembly 400 drives the pipe to rotate during clamping, facilitating omnidirectional welding of the flange and pipe ends without requiring workers to constantly adjust their position or the position and angle of the pipe during welding.

[0040] In some embodiments, see Figure 4 and combined Figure 2The clamping assembly 300 includes a fixing member 301 and a clamping member 302. The clamping member 302 is a cuboid block that clamps the opposite ends of the pipe wall, forming two opposing contact points with the pipe wall, thus restricting the horizontal position of the pipe. The fixing member 301 is fixedly connected to the first open end face and has a first clearance hole that corresponds to the opening of the connecting sleeve 200. The clamping member 302 is located on the side of the fixing member 301 away from the first open end face. The clamping member 302 can move toward or away from the first clearance hole to lock or release the clamped member 302. Along the circumference of the first clearance hole, the fixing member 301 and the clamping member 302 are fixed relative to each other.

[0041] Based on this, the fixing member 301 is disposed at one end of the support base 100 away from the drive assembly 400, and the connecting sleeve 200 can drive the fixing member 301 and the clamping member 302 to rotate simultaneously. For example, one end of the connecting sleeve 200 is welded to the fixing member 301. The clamping member 302 is disposed at one end of the fixing member 301 away from the drive assembly 400, and the fixing member 301 provides installation space for the clamping member 302.

[0042] In other embodiments, please refer to Figure 4 and combined Figure 2 The clamping assembly 300 includes a fixing member 301 and a clamping member 302. The clamping member 302 is an arc-shaped claw that clamps the opposite ends of the pipe wall, forming two opposing contact surfaces with the pipe wall, thus restricting the horizontal position of the pipe. The fixing member 301 is fixedly connected to the first open end face and has a first clearance hole that corresponds to the opening of the connecting sleeve 200. The clamping member 302 is located on the side of the fixing member 301 away from the first open end face. The clamping member 302 can move toward or away from the first clearance hole to lock or release the clamped member 302. Along the circumference of the first clearance hole, the fixing member 301 and the clamping member 302 are fixed relative to each other.

[0043] Based on this, the fixing member 301 is disposed at one end of the support base 100 away from the drive assembly 400, and the connecting sleeve 200 can drive the fixing member 301 and the clamping member 302 to rotate simultaneously. For example, one end of the connecting sleeve 200 is welded to the fixing member 301. The clamping member 302 is disposed at one end of the fixing member 301 away from the drive assembly 400, and the fixing member 301 provides installation space for the clamping member 302.

[0044] In some embodiments, see Figure 4 and combined Figure 5The clamping assembly 300 also includes an adjusting rod 303, which is rotatably connected to the side surface of the fixing member 301 opposite to the first opening end face; there are multiple clamping members 302, including a first clamping member 3021 and a second clamping member 3022 arranged opposite to each other. The first clamping member 3021 and the second clamping member 3022 are both sleeved on the adjusting rod 303 and threadedly engaged with the adjusting rod 303; the first clamping member 3021 and the second clamping member 3022 are threaded in opposite directions to the adjusting rod 303.

[0045] Based on this, the adjusting rod 303 is used to control the relative or disjoint movement of the first clamping member 3021 and the second clamping member 3022, thereby clamping or releasing the pipe. The first clamping member 3021 and the second clamping member 3022 are screwed in opposite directions to the adjusting rod 303. When the adjusting rod 303 is rotated clockwise, the first clamping member 3021 and the second clamping member 3022 move towards the center simultaneously to achieve rapid clamping, while counterclockwise rotation releases them synchronously.

[0046] For example, the adjusting rod 303 is provided with rotating disks 306 at both ends. The rotating disks 306 are manually rotated, causing the first clamping member 3021 and the second clamping member 3022 to move in opposite directions, thereby fixing the pipe. One end of the first clamping member 3021 and the second clamping member 3022 has a threaded hole for mounting the adjusting rod 303.

[0047] As another example, the adjusting rod 303 can be a two-way lead screw or a one-way lead screw.

[0048] It is understandable that when the adjusting rod 303 is a two-way lead screw, it has two threaded segments with opposite directions of rotation, symmetrically distributed axially. In this case, the threads in the threaded holes of the first clamping member 3021 and the second clamping member 3022 are in the same direction. The threaded hole of the first clamping member 3021 engages with one of the threaded segments, and both threads have the same direction of rotation; the threaded hole of the second clamping member 3022 engages with the other threaded segment, and both threads have the same direction of rotation. By rotating the adjusting rod 303, the first clamping member 3021 and the second clamping member move relative to each other or move apart simultaneously.

[0049] When the adjusting rod 303 is a one-way lead screw, it has two threaded segments with the same direction of rotation. At this time, the threads in the threaded holes of the first clamping member 3021 and the second clamping member 3022 are in opposite directions. The threaded hole of the first clamping member 3021 mates with one of the threaded segments, and the two threads rotate in opposite directions; the threaded hole of the second clamping member 3022 mates with the other threaded segment, and the two threads rotate in the same direction. By rotating the adjusting rod 303, the first clamping member 3021 and the second clamping member move relative to each other or move apart simultaneously.

[0050] In other embodiments, please refer to Figure 4and combined Figure 5 The clamping assembly 300 also includes a connecting plate 305. There are multiple connecting plates 305, including a first connecting plate 3051 and a second connecting plate 3052 that are arranged opposite to each other. The first connecting plate 3051 and the second connecting plate 3052 are both sleeved on the adjusting rod 303. One end face of the first connecting plate 3051 and the second connecting plate 3052 are fixed to the opposite ends of the surface of the fixing member 301 on the side away from the first opening end face.

[0051] Based on this, the first connecting plate 3051 and the second connecting plate 3052 have grooves 3053 on the side facing away from the pipe to install the adjusting rod 303. For example, one end face of the first connecting plate 3051 and the second connecting plate 3052 is welded to the fixing member 301 to fix the adjusting rod 303 and prevent the adjusting rod 303 from being misaligned during rotation.

[0052] In some embodiments, see Figure 4 The adjusting rod 303 is a two-way lead screw.

[0053] Based on this, the thread structure of the bidirectional lead screw is a left-right symmetrical design, with both left-hand and right-hand threads present on the lead screw. When the lead screw rotates, it achieves bidirectional drive for the first clamping member 3021 and the second clamping member 3022.

[0054] In some embodiments, see Figure 4 The first clamping member 3021 has a first clamping part 3023 on the side facing the second clamping member 3022, and the second clamping member 3022 has a second clamping part 3024 on the side facing the first clamping member 3021. The first clamping part 3023 and the second clamping part 3024 are arranged opposite each other in the radial direction of the receiving hole 500, and the first clamping part 3023 and the second clamping part 3024 are locking blocks.

[0055] For example, the first clamping part 3023 and the second clamping part 3024 are welded to the first clamping member 3021 and the second clamping member 3022. The first clamping part 3023 and the second clamping part 3024 can be two triangular prisms with the same shape, and the tips of the two triangular prisms face each other. The inclined surfaces of the four triangular prisms form a space that matches the pipe, and fix the pipe in the circumferential direction.

[0056] In another example, the first clamping part 3023 and the second clamping part 3024 are provided with a fixing pad 3025 on the side that contacts the pipe, so that the pipe is clamped more firmly by the fixing pad 3025.

[0057] In other embodiments, please refer to Figure 4The first clamping member 3021 has a first clamping part 3023 on the side facing the second clamping member 3022, and the second clamping member 3022 has a second clamping part 3024 on the side facing the first clamping member 3021. The first clamping part 3023 and the second clamping part 3024 are arranged opposite each other in the radial direction of the receiving hole 500, and the first clamping part 3023 and the second clamping part 3024 are claws.

[0058] For example, the first clamping part 3023 and the second clamping part 3024 are welded to the first clamping member 3021 and the second clamping member 3022. The first clamping part 3023 and the second clamping part 3024 can each have a claw structure of the same shape. The two claw structures form a space that matches the pipe and fixes the pipe in the circumferential direction.

[0059] In another example, the first clamping part 3023 and the second clamping part 3024 are provided with a fixing pad 3025 on the side that contacts the pipe, so that the pipe is clamped more firmly by the fixing pad 3025.

[0060] In some embodiments, see Figure 4 The clamping assembly 300 also includes a guide rod 304, which is disposed on the side surface of the fixing member 301 opposite to the first opening end face. The guide rod 304 and the adjusting rod 303 are arranged radially opposite to each other along the receiving hole 500. The first clamping member 3021 and the second clamping member 3022 are both sleeved on the guide rod 304 and slidably connected to the guide rod 304.

[0061] For example, the first clamping member 3021 and the second clamping member 3022 have through holes at the ends opposite to the mounting adjustment rod 303 for mounting the guide rod 304. The first clamping member 3021 and the second clamping member 3022 are both sleeved on the guide rod 304 and slidably connected to the guide rod 304. The guide rod 304 is used to constrain the movement direction of the first clamping member 3021 and the second clamping member 3022 to ensure precise linear movement.

[0062] In some embodiments, see Figure 4 and combined Figure 3 The drive assembly 400 includes a transmission component 401 and a drive component 402. The transmission component 401 is fixedly connected to the second open end face; the drive component 402 and the transmission component 401 are driven by gears.

[0063] Based on this, the drive component 402 serves as a power source, transmitting its own power to the transmission component 401. The drive component 402 and the transmission component 401 are connected by gears, which can achieve precise conversion between the speed of the drive component 402 and the speed of the transmission component 401.

[0064] For example, the gear transmission between the driving component 402 and the transmission component 401 can be a spur gear transmission or a helical gear transmission. The transmission component 401 may include a first gear 4011, which is fixedly connected to the second open end face. The driving component 402 may include a motor 4021, a rotating rod 4022, and a second gear 4023. The motor 4021 can drive the second gear 4023 to rotate through the rotating rod 4022, so that the second gear 4023 can drive the first gear 4011 to rotate.

[0065] In another example, a support frame 4024 is provided below the motor 4021, which facilitates the motor 4021 to drive the rotating rod 4022 to drive the gear 2 4023 to rotate and mesh with the gear 1 4011, thus saving space.

[0066] In some embodiments, see Figure 4 and combined Figure 2 and Figure 3 The transmission component 401 includes a second clearance hole, which corresponds to the opening of the connecting sleeve 200. The outer peripheral surface of the transmission component 401 is provided with an external gear that drives the gear of the driving component 402.

[0067] Based on this, the second clearance hole corresponds to the opening of the connecting sleeve 200. The outer circumferential surface of the transmission component 401 is provided with an external gear that drives the gear of the driving component 402. The transmission component 401 drives the connecting sleeve 200 to rotate, so as to realize the rotation of the fixed pipe, thereby facilitating the welding of the flange and the pipe.

[0068] For example, the transmission component 401 is welded to the connecting sleeve 200.

[0069] In some embodiments, see Figure 1 and combined Figure 3 The wall of the receiving hole 500 is provided with a rotating groove 102, at least a portion of the connecting sleeve 200 is received in the rotating groove 102, and at least a portion of the connecting sleeve 200 is rotatably connected to the rotating groove 102.

[0070] For example, the connecting sleeve 200 is at least partially engaged in the rotating groove 102, which allows the connecting sleeve 200 to rotate flexibly at different angles while maintaining axial stability.

[0071] Since the processing equipment provided in this application includes a chuck as described in any of the above embodiments, both can solve the same technical problem and achieve the same effect, and this application will not elaborate further on this.

[0072] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
