Description

Technical Field

[0001] The invention relates to the technical field of pipe fitting processing and manufacturing, and specifically proposes a geothermal energy connecting pipeline positioning processing device. Background Art

[0002] The manifold pipe is a key pipe fitting in the geothermal energy connection pipeline system. It can evenly distribute the hot water from the heat source to each heating circuit, and also collect the cooled water and send it back to the heat source for reheating, playing the role of distribution and collection. The manifold pipe generally has multiple evenly distributed branch pipe joints. Some of the branch pipe joints are joint structures formed by additional welding, and some are joint structures formed by drilling and tapping on the manifold pipe. The manifold pipe itself can be a square pipe or a round pipe structure.

[0003] like Fig. 9 The figure shows a water distributor pipe with a square tube structure. Its main body is a square tube structure, and both ends of the tube body are round tube joints with internal threads. The branch pipe joints evenly distributed thereon are made by drilling and tapping. During actual processing, holes are first drilled with a flanging drill bit, and an inner flanging is simultaneously formed in the water distributor pipe, and then the inner flanging hole is tapped to form the branch pipe joint.

[0004] like Fig. 9 The water distributor pipe shown has two groups of pipe joints on the side walls at two relative positions. Among the two relative branch pipe joints in the two groups, one branch pipe joint is used to install the branch pipe, and the other branch pipe joint is generally used to install a valve or other device that matches the branch pipe at the relative position, thereby realizing independent control of the branch pipe.

[0005] In the existing processing process, the manifold pipe is generally first clamped and fixed by a clamp, and then multiple branch pipe joints on one side are drilled and flanging one by one, and then each flanging hole is tapped one by one. For the convenience of processing, the processing equipment generally has at least two processing axes, one end of which is equipped with a flanging drill bit, and the other end of which is equipped with a tap. However, the above processing equipment has the following problems in actual processing: 1) The method of drilling first and then tapping is adopted. When the flanging drill bit completes drilling, the taps need to be realigned one by one. Therefore, if there is an alignment error during the secondary alignment, it will affect the quality of the thread formed after tapping, and then affect the connection strength and sealing at the branch pipe joints.

[0006] 2) After the processing of one side of the manifold pipe is completed, the clamp needs to be manually loosened, turned over manually, and clamped again. Obviously, simple repetitive operations are required during mass production, which greatly affects the overall production and processing efficiency.

[0007] 3) A large amount of heat is generated at the branch joints during the flanging and drilling process. In actual processing, natural cooling is basically used for the cooling of the branch joints, and the time difference between drilling and tapping is utilized. However, the method of drilling one by one and then tapping one by one inevitably makes the cooling time of each branch joint different, that is, the cooling state is different. The physical state of the branch joints that are not effectively cooled in time is not conducive to the tapping process, which also affects the connection quality and sealing of each branch joint. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] A geothermal energy connection pipeline positioning and processing device, mainly for Fig. 9 The branch pipe joints on both sides of the water distributor pipe 4 are processed and formed; Figure 1 , Figure 2 , Figure 3 , Figure 5 and Fig. 9As shown, the device includes a main frame 1, on which two horizontally symmetrically arranged inner support end clamping mechanisms 2 for clamping and positioning the two ends of the pipe fitting are installed horizontally and rotatably; the inner support end clamping mechanism 2 includes an electric turntable 21 welded to the main frame 1, and an inner extension cylinder 22 is coaxially fixed to the center of the electric turntable 21 by bolts, and an end clamping plate 23 for clamping the end of the water distributor pipe 4 is welded at the output end of the inner extension cylinder 22, and a center block 231 is horizontally welded at the center of the end clamping plate 23, and the end clamping plate 23 is welded to the center of the end clamping plate 23. Three inner support components 24 are installed circumferentially on 23; the inner support component 24 includes a roller frame 241 installed on the end clamping disk 23 in a radial sliding fit, and an elastic connecting member 242 is fixedly connected between the roller frame 241 and the center block 231. The elastic connecting member 242 is made of rubber material, and an inner support roller 243 is installed horizontally and rotatably on the roller frame 241. In order to facilitate the inner support roller 243 to extend into the port of the water distributor pipe 4, the end of the inner support roller 243 away from the end clamping disk 23 is conical.

[0035] In the present invention, two relatively arranged inner support end clamping mechanisms 2 replace the existing Fig. 9 The clamp for clamping the water distributor pipe 4 on both sides shown in the figure can extend the two sets of inner support components 24 into the two side ports of the water distributor pipe 4 during actual processing. Under the elastic force of the elastic connector 242, the inner support roller 243 is pressed against the inner wall of the round tube port. At the same time, driven by the two inner extension cylinders 22, the two ends of the water distributor pipe 4 are clamped between the two end clamps 23. During the clamping process, the two sides of the water distributor pipe 4 to be processed can be kept close to horizontal. Therefore, the preliminary clamping and positioning of the water distributor pipe 4 is achieved through the cooperation of the two inner support end clamping mechanisms 2. In addition, when the two electric turntables 21 are started at the same time, the water distributor pipe 4 can be driven to rotate as a whole, so as to quickly switch the processing surface, which solves the problem that the existing clamp needs to be loosened and clamped during processing and needs to be clamped again after changing the surface. The processing is more convenient and the problem of positioning error in the two clamping adjustment processes is avoided. It should be added that the electric turntable 21 is an existing device and has its own locking structure. In this embodiment, it rotates ninety degrees intermittently each time.

[0036] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Fig. 9As shown, the main frame 1 is equipped with a plurality of processing execution assemblies 3 which are sequentially distributed along the relative setting direction of the two inner support end clamping mechanisms 2 and have adjustable spacing. A spacing guide rail 11 is horizontally welded on the main frame 1, and the processing execution assembly 3 includes a cooling component 31. The cooling component 31 includes a sliding seat 311 which is slidably mounted on the spacing guide rail 11. A cooling pipe 312 is horizontally welded on the sliding seat 311. A cooling nozzle 313 is welded at one end of the cooling pipe 312. The cooling pipe 312 is fed with a cold air flow through an external pipeline, and the cold air flow is ejected through the cooling nozzle 313. The cooling nozzle 313 is an existing electronically controlled nozzle. In this embodiment, the cooling nozzle 313 is horizontally and vertically arranged relative to the center block 231 of the end clamping plate 23. A double-ended conduit 314 is welded on the cooling tube 312, and the two pipe ends of the double-ended conduit 314 are symmetrically arranged in an upper and lower manner; guide pillars 321 are correspondingly installed at both ends of the double-ended conduit 314 for sliding cooperation, and bearing plates 32 are horizontally welded at the ends of the two guide pillars 321, and processing shafts 33 are vertically rotatably installed on the two bearing plates 32, and the two processing shafts 33 are vertically oppositely arranged. In this embodiment, a flanging drill is installed at the end of the upper processing shaft 33, and a tap of a corresponding model is installed at the end of the lower processing shaft 33; a driving beam 12 is installed horizontally and slidably between multiple bearing plates 32 located on the same side of the cooling component 31 in multiple processing execution assemblies 3, and the driving beam 12 is vertically slidably installed on the main frame 1, and a cylinder that is connected to the two driving beams 12 in a one-to-one corresponding manner can be installed on the main frame 1, and the driving beam 12 is driven by the cylinder to move along the main frame 1, thereby driving the multiple processing shafts 33 connected thereto to move synchronously. It should be noted that the cylinder is not shown in the accompanying drawings.

[0037] In addition, it is important to add that the number of processing execution assemblies 3 shown in the figure does not represent the actual number of assemblies assembled in the device. The actual number of assemblies assembled is greater than the number of single-side branch pipe joints in the manifold pipe 4. During actual processing, a corresponding number of processing execution assemblies 3 can be selected to participate in processing and manufacturing, and the distribution spacing of multiple processing execution assemblies 3 can be adjusted according to the spacing of the single-side branch pipe joints in the manifold pipe 4 to be processed, and can directly drive the processing execution assembly 3 to slide along the spacing guide rail 11. After the adjustment is completed, the sliding seat 311 can be locked with the spacing guide rail 11, or the corresponding spacing adjustment structure in the existing multi-axis processing equipment can be installed to realize automatic adjustment of the spacing. The shaft end of the processing shaft 33 can be installed with a pulley, and the synchronous drive of multiple processing shafts 33 on the same side can be realized through a synchronous belt, and a tensioning pulley mechanism can be installed to realize the tensioning of the synchronous belt after the spacing adjustment. The selection of the above technical solutions can meet the processing requirements of this device for manifold pipes 4 of multiple specifications.

[0038] like Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the two bearing plates 32 in the same processing execution assembly 3 are also equipped with correction and positioning components 34, and the two correction and positioning components 34 are arranged vertically opposite to each other. The correction and positioning component 34 includes a guide shaft 341 with a square structure that is vertically slidably installed on the bearing plate 32, and a double fork frame 342 is horizontally welded at one end of the guide shaft 341. A compression spring 343 is sleeved on the guide shaft 341, and the two ends of the compression spring 343 are respectively welded to the bearing plate 32 and the double fork frame 342; the double fork frame 342 is provided with two cantilever slide rails 3421 distributed along the relative setting direction of the two inner support end clamping mechanisms 2, and the two cantilever slide rails 3421 are distributed on both sides of the processing shaft 33, and the two cantilever slide rails 3421 are installed with clamping guide components 344. The clamping guide assembly 344 includes a torque arm 345 connected by a torsion spring and vertically rotatably installed on a cantilever slide rail 3421. It should be noted that the torsion spring is not shown in the accompanying drawings. In this embodiment, the rotation center axis of the torque arm 345 is located on the same vertical plane as the center axis of the processing axis 33 and the clamping center axis of the inner support end clamp mechanism 2; two relatively arranged clamping blocks 346 are slidably installed on the cantilever slide rail 3421, and the clamping block 346 includes a vertical side clamping portion and a horizontal clamping portion, and a pin shaft 3461 is fixed on the horizontal clamping portion. The torque arm 345 is provided with two waist-shaped holes 3451 which correspond to the two clamping blocks 346 one by one, and the pin shaft 3461 is inserted into the corresponding waist-shaped holes 3451.

[0039] After the preliminary positioning and clamping of the manifold pipe 4 is completed by the cooperation of the two inner support end clamping mechanisms 2, the processing operation can be performed, which is specifically described as follows: First, the driving beam 12 located above drives the upper multiple structures composed of the bearing plates 32, the processing shafts 33 and the correction and positioning components 34 to descend as a whole. The sliding cooperation between the guide column 321 and the double-headed guide tube 314 provides auxiliary guidance for vertical advancement. During the descent process, the horizontal side surfaces of the manifold pipe 4 will relatively enter between the vertical side clamping parts of the two clamping blocks 346 in the clamping guide assembly 344. Under the torsion force of the torsion spring, the two sides of the manifold pipe 4 are clamped by the vertical side clamping parts of the two clamping blocks 346. The cooperation of the single torsion spring and the torque arm 345 is adopted, so that the two clamping blocks 346 are always relative to the torque arm 345. The rotating center axis of the manifold 4 is evenly distributed, so as to better realize the intersection of the center axis of the manifold 4 and the center axis of the processing axis 33. As it continues to descend, the compression spring 343 will be gradually compressed, and the horizontal clamping part of the clamping block 346 will be pressed against the side of the manifold 4 to be processed. The auxiliary positioning and clamping of the manifold 4 by the correction positioning component 34 improves the processing stability. During the auxiliary positioning and clamping process, the manifold 4 passively adjusts the positioning posture under the auxiliary rolling of the inner support roller 243, so that the center axis of the manifold 4 is located at the processing center position, and the side to be processed remains horizontal. As it continues to descend, while maintaining the auxiliary positioning and clamping state, the multiple processing axes 33 located above simultaneously complete the inner flanging drilling of multiple branch pipe joints through the flanging drill bit. After the drilling is completed, the upper processing axis 33 returns to the initial position.

[0040] Next, the electric turntable 21 starts to rotate ninety degrees, completing the side flipping of the inner flange drilling to face multiple cooling components 31, and the cooling nozzle 313 is started. Multiple cooling nozzles 313 are aimed at multiple branch joints for synchronous rapid cooling to reduce the impact of the high temperature state at the branch joints on subsequent tapping.

[0041] Subsequently, the electric turntable 21 rotates another ninety degrees, and the processed side after cooling is flipped to a downward state, and the opposite side to be processed is flipped to an upward state. At this time, the upper and lower processing axes 33 are started synchronously, and the upper and lower correction and positioning components 34 also synchronously assist in clamping and positioning the water distributor pipe 4. The multiple processing axes 33 located at the bottom use taps to synchronously tap the multiple branch pipe joints that have completed cooling, and the multiple processing axes 33 located at the top use flanging drills to complete the flanging drilling of multiple branch pipe joints.

[0042] Then, continue to rotate and change the surface, and synchronously cool the branch pipe joint that has just been drilled. Finally, continue to change the surface, and the processing shaft 33 located at the bottom taps the branch pipe joint that has just been cooled, thereby completing all the processing of the two groups of pipe joints. Then, loosen the internal support end clamping mechanism 2 and take out the water distributor pipe 4.

[0043] The present invention provides a geothermal energy connection pipeline positioning processing device, which can be used for positioning processing of the branch pipe joints of the water distributor pipe 4. In the device, on the basis of the two inner support end clamping mechanisms 2 being able to actively rotate and change the surface of the water distributor pipe 4, multiple groups of processing shafts 33 can be used to synchronously and quickly complete the flanging drilling and tapping of multiple branch pipe joints on a single side, thereby greatly improving the overall processing efficiency. Through the layout of the cooling component 31 and the two processing shafts 33 in the processing execution assembly 3, the branch pipe joint can be quickly cooled after the flanging drilling is completed and before the tapping processing, so as to eliminate the influence of temperature on the tapping forming quality. The synchronous drilling and synchronous cooling methods avoid the differentiation of the cooling states of multiple branch pipe joints, thereby ensuring the consistency of the subsequent tapping processing quality. The cooling component 31 in the processing execution assembly 3 and the layout of the two processing shafts 33 can be used to quickly cool the branch pipe joint after the flanging drilling is completed and before the tapping processing, so as to eliminate the influence of temperature on the tapping forming quality. In addition, the synchronous drilling and synchronous cooling methods avoid the differentiation of the cooling states of multiple branch pipe joints, thereby ensuring the consistency of the subsequent tapping processing quality. The relative position of the cooling component 31 and the two processing axes 33 is fixed, forming a three-in-one structure, which is not affected by the spacing adjustment, and there is no problem of relative flanging drilling and re-alignment during tapping in the existing processing process; in addition, on the basis of the preliminary clamping and positioning of the inner support end clamping mechanism 2, the water distributor pipe 4 is assisted in correction and positioning by the correction and positioning component 34 during the drilling and tapping process, thereby ensuring the accuracy of the processing and positioning of the water distributor pipe 4, and eliminating the influence of the angular error that may exist in the flanging conversion process on the positioning posture of the water distributor pipe 4; in summary, the device provided by the present invention changes the existing processing method, improves the convenience of processing, processing positioning accuracy and overall processing efficiency, and improves the processing and molding quality, thereby ensuring the connection strength and sealing at the branch pipe joints of the water distributor pipe 4.
