Description

Technical Field

[0001] The utility model relates to the field of pressure vessel preparation, and particularly to a head assembly and alignment table. Background Art

[0002] The preparation of pressure vessels includes the step of head assembly and alignment. After the cylinder body and the head are aligned, they are welded and fixed. For small pressure vessels, manual operation is sufficient, while for medium and large pressure vessels, head assembly equipment is required, and it is difficult to complete only through manual operation. Based on this, a number of patented technologies have disclosed head assembly equipment. CN112792493B discloses a double-layer cylinder head assembly device, which positions the inner cylinder body, the outer cylinder body and the head by a centering device that can be inserted into the inside of the inner cylinder body and limit the inner cylinder body, and an outer clamping claw mechanism that clamps the outer wall of the outer cylinder body and limits the outer cylinder body, so that the center heights of the three are the same, and then welding and fixing are carried out. However, if there is an error or inclination of the head position in the outer clamping claw mechanism of this equipment, it is very difficult to make the center height of the head consistent with the center lines of the inner and outer cylinder bodies, resulting in more difficult subsequent height alignment between the outer cylinder body and the head. Summary of the Utility Model

[0003] Based on this, the utility model provides a head assembly and alignment table, which includes:

[0004] A head clamping mechanism, which includes a base, a head clamping device arranged on the base, a flipping device for flipping the head clamping device between the loading position and the working position, and a self-rotating device for making the head clamping device rotate; wherein the head clamping device includes a plurality of clamping teeth surrounding a circle, a flattening device arranged on the clamping teeth, and a positioning device located at the center of the circle of the clamping teeth, and the opening size of the clamping teeth can be adjusted through a clamping tooth track;

[0005] A transmission mechanism for transmitting the cylinder body, which includes a telescopic roller device arranged in the transmission mechanism and a lifting roller device arranged between the transmission mechanism and the head clamping mechanism;

[0006] An auxiliary guiding mechanism spanning the transmission mechanism and arranged for reciprocating movement, which includes a vertical beam and a cross beam device respectively slidably connected to the vertical beam, wherein the cross beam device includes a slider and a guiding member, and the slider is located between the guiding member and the vertical beam.

[0007] In one embodiment, the head clamping device includes a disc and a radially arranged clamping tooth track, one end of the clamping tooth is engaged with the clamping tooth track and the clamping tooth is slidably arranged on the clamping tooth track.

[0008] In one embodiment, the flattening devices are arranged on the clamping teeth at intervals, and each flattening device includes a buckle for fixedly flattening the head, a driver for driving the buckle to expand and contract, and a concave track. The buckle is arranged in the concave track, and the driver and the buckle are respectively arranged on the inner and outer sides of the clamping tooth.

[0009] The clamping teeth can slide on the clamping tooth track, so that the opening size of the clamping teeth can be changed, and then heads of different sizes can be fixed; preferably, the driver can be a cylinder or a motor, and the driver and the buckle form a seesaw mode. When the driver pulls, the buckle extends out of the concave track to flatten the head, and when the driver releases, the buckle retracts into the concave track. Preferably, the flattening devices are arranged at intervals on the clamping teeth to give adjustment space for the head.

[0010] In one embodiment, the positioning device includes a positioning disc, several vertical rods standing on the positioning disc, and positioning rollers located at the ends of the vertical rods.

[0011] In one embodiment, the positioning device is arranged to move forward and backward, and the positioning disc is connected to a telescopic forward and backward rod.

[0012] The positioning device and the flattening device are cooperative mechanisms. The head is fixed through the buckle, and the center position of the head moves through the positioning rollers, so that the end face of the head is parallel to the end face of the cylinder section when in the working position, which is convenient for the two to be paired. After the pairing and welding are completed, the head and the cylinder section are pushed out by the elongation of the forward and backward rod, so that the positioning device extends forward, and then the welded head and cylinder section are pushed out and transferred to the next working station.

[0013] In one embodiment, the base is located on the support table, and the base reciprocates through a sliding rail device.

[0014] The base reciprocates through the sliding rail device, so as to facilitate receiving heads at different positions during feeding and retreating after the pairing and welding of the head and the cylinder section.

[0015] In one embodiment, the auxiliary guiding mechanism reciprocates through a walking device.

[0016] The auxiliary guiding mechanism adjusts its position to adapt to cylinder sections of different lengths, which is convenient for subsequent guiding and pushing of the cylinder sections. And the crossbeam device can be adjusted up and down, so as to facilitate the transportation of cylinder sections of different diameters to pass through, and prevent cylinder sections with large diameters from not being able to pass through the crossbeam device.

[0017] In one embodiment, the transmission mechanism is arranged as a roller conveyor. The roller conveyor is arranged with several V-shaped rollers, and the starting position of the telescopic roller device is lower than the V-shaped rollers.

[0018] The V-shaped rollers are more suitable for the transportation of cylinders and are not easy to fall off the transportation line.

[0019] In one embodiment, the transmission mechanism further includes a lifting table. The telescopic roller device, the lifting roller device, and the transmission roller section between the telescopic roller device and the lifting roller device are arranged on the lifting table.

[0020] In one embodiment, the head clamping mechanism further includes a limiting device for limiting the position of the head clamping device when it is in the working position. The limiting device is arranged on the base and close to the lifting roller device.

[0021] The crossbeam device in the auxiliary guiding mechanism includes a slider and a guide member arranged on the slider. Preferably, the guide member is roller-shaped, wherein the roller-shaped guide member rotates around the axis. During the welding process of the cylinder section and the head, the height of the crossbeam device can be moved, and the roller-shaped guide member rotates as the crossbeam device moves up and down, thereby guiding and pushing the cylinder body. Alternatively, the height of the crossbeam device can be directly adjusted to allow the roller-shaped guide member to press the position where there is a gap between the head and the cylinder body, so that the cylinder body and the head are butted at the gap, thereby making the butt joint where the cylinder body and the head need to be welded tightly, which is convenient for spot welding.

[0022] The telescopic roller device includes a telescopic roller, a telescopic roller frame and a roller telescopic driving device. The distance between the telescopic roller frames is adjusted by the roller telescopic driving mechanism to raise or lower the height of the telescopic roller so that the telescopic roller is higher or lower than the roller table. Preferably, the roller telescopic driving device is realized by a screw ball or a cylinder. Preferably, the telescopic roller device includes at least one group of telescopic rollers.

[0023] The lifting roller device includes a lifting roller, a lifting roller frame for mounting the lifting roller, and a roller lifting drive device. The roller lifting drive device adjusts the height of the lifting roller frame by extending and shortening a hydraulic rod, thereby adjusting the height of the lifting roller, so that the lifting roller is higher or lower than the roller table. Preferably, the lifting roller device includes at least one set of lifting rollers. The telescopic roller device is located in the transmission mechanism, and the lifting roller device is between the head clamping device and the outer end of the transmission mechanism.

[0024] The height position of the cylinder section is adjusted by the telescopic roller device and the lifting roller device. In addition, the telescopic roller device and the lifting roller device do not use the same method to adjust the roller height, so that the height of the cylinder section can be adjusted independently between the two, which is more in line with the actual production process. By adjusting the telescopic roller device and the lifting roller device, the center lines of the head and the cylinder can be aligned at the same height, which is convenient for alignment.

[0025] When the telescopic roller device and the lifting roller device are not in use, the starting positions are lower than the roller table, so that the transmission mechanism can transport the cylinder segment easily.

[0026] When the head and the cylinder segment are assembled, the clamping teeth clamp the head and the cylinder body, and the disc in the head clamping device rotates through the self-rotation device, driving the raised rollers in the telescopic roller device and / or the lifting roller device to rotate, so that the head and the cylinder segment rotate 360 degrees, and the positions where welding is required at the connection between the cylinder body and the head are welded in turn at the welding position.

[0027] Preferably, the lifting table is controlled by a hydraulic device to facilitate adjusting the height difference between the cylindrical body of different sizes and the head clamping device, so as to facilitate the assembly of cylindrical bodies and heads with different diameters.

[0028] The limiting device is arranged below the base and close to the lifting roller device to limit the head clamping device in the working position. At the same time, it can accurately position the position of the head clamping mechanism of products with the same size during the head assembly process, avoiding the fuzzy positioning of the head clamping mechanism and delaying the assembly time.

[0029] Technical effects:

[0030] 1. By positioning the center line of the head through the positioning device, it is ensured that the end face of the head is parallel to the end face of the cylindrical body, thereby reducing the error during the assembly process.

[0031] 2. The clamping teeth in the head clamping device slide along the clamping tooth track, and the opening size formed by the clamping teeth can be adjusted according to the size of the head. Combined with the sliding buckle arranged on the clamping teeth, different sizes of heads can be fixed, which is suitable for intelligent production.

[0032] 3. The gantry type auxiliary guiding mechanism is adopted, and the cross beam of the auxiliary guiding mechanism is set to be height adjustable. During the assembly process, the cross beam device pushes the cylinder section forward to be assembled with the head, and the height is adjusted through the cross beam device, so that all welding positions of the cylindrical body and the head are butted and spot welded during the welding process.

[0033] 4. The telescopic roller device and the lifting roller device are adopted to adjust the center line position of the cylinder section, so that the height position of the center line of the head and the cylinder section is consistent; in addition, the rotation device is adopted to rotate the disc, so that the welding positions required for the butt joint of the head and the cylinder section reach the welding operation positions in turn to complete the welding, saving labor costs and improving efficiency.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0041] For specific reference, please refer to Figures 1-4, the utility model discloses a head butt - assembling table, which comprises a head clamping mechanism 10, an auxiliary guiding mechanism 20 and a transmission mechanism 30. The head clamping mechanism 10 includes a head clamping device 11, a reciprocating base 12, a support table 13, a sliding rail device 14 arranged on both sides of the support table 13, a flipping device 15 for flipping the head clamping device 11, and a self - rotating device 16 for making the head clamping device 11 rotate self - sufficiently. The head clamping device 11 is placed on the base 12, the base 12 is located on the support table 13, and the base 12 reciprocates through the sliding rail device 14. The sliding rail device 14 includes a crawler 141 and a sliding rail 142. The operation of the crawler 141 makes the base 12 slide on the sliding rail 142, so as to facilitate feeding. When the head clamping device 11 is in the feeding position, that is, the clamping teeth 111 open upward, the transported head is clamped through the clamping teeth 111. The head clamping device 11 includes a plurality of clamping teeth 111, and a flattening device 112 is arranged at intervals on the clamping teeth 111. The flattening device 112 includes a buckle 1121, a hydraulic cylinder 1122 and a concave rail 1123. The hydraulic cylinder 1122 and the buckle 1122 are respectively arranged on the inner and outer sides of the clamping teeth 111. The buckle 1121 slides in the concave rail 1123 to fix heads of different sizes, and the buckle 1121 expands and contracts through the hydraulic cylinder 1122. When the buckle 1121 extends, it fixes and flattens the head. After the buckle 1121 retracts into the concave rail 1123, the head and the cylinder section are butted.

[0042] The head clamping device 11 further includes a retractable rod 113 and a positioning device 114. The positioning device 114 includes a positioning disc 1141, a plurality of vertical rods 1142 standing on the positioning disc 1141, and positioning rollers 1143 located at the ends of the vertical rods 1142. When the center line of the head is in an inclined position, through the sliding adjustment of the positioning rollers 1143, the center line of the head is adjusted to be at the same height as the center line of the cylinder body for subsequent butt - assembling and installation. And the center position of the positioning disc 1141 is connected to the retractable rod 113, and the retractable rod 113 is telescopically arranged, so that the positioning device 114 moves forward and backward.

[0043] It should be further noted that the clamping teeth 111 stand on a disc 115. A plurality of clamping - tooth tracks 1151 are arranged on the disc 115, and the clamping - tooth tracks 1151 are radially arranged and concentrated on the positioning device 114. One end of the clamping teeth 111 is slidably connected to the clamping - tooth track 1151, so as to adjust the opening size formed by the clamping teeth 111, so as to be applicable to heads of different sizes. In addition, the end of the clamping teeth 111 far from the disc 115 is provided with a slope, which facilitates the subsequent guiding of the cylinder section into the clamping teeth 111.

[0044] When in the loading position, adjust the positions of the clamping teeth 111 and the buckle 1121 to ensure that the head is clamped and fixed. Flip the head clamping device 11 to the working position through the flipping device 15. The included angle between the working position and the loading position is 90 degrees. When the head clamping device 11 is in the working position, after the head and the cylinder are aligned, spot welding is performed. The welding equipment is generally in a relatively fixed position. At this time, the disc 115 in the head clamping device 11 is rotated by the self-rotation device 16. The self-rotation device 16 is arranged on the side of the disc 115 opposite to the clamping teeth 111 and is driven by a motor. The disc 115 is driven to rotate by the self-rotation device 16 so that the positions to be welded at the joint of the head and the cylinder section are welded in sequence. After welding is completed, the advancing and retracting rod 113 advances to push the positioning device 114 forward, thereby pushing out the head and the cylinder, and transporting them to the next station through the transmission mechanism 30. It should be further noted that the advancing push rod 113 here can be a hydraulic rod, a ball screw mechanism, a pneumatic rod, etc. The self-rotation device 16 can be powered by a motor or a cylinder to drive the disc 115 to rotate around its central axis.

[0045] The head clamping mechanism 10 further includes a limiting device 17. The limiting device 17 is arranged below the base 12 and close to the lifting roller device 32 to limit the head clamping device 11 when it is in the working position. At the same time, it can accurately position the position of the head clamping mechanism 10 of products with the same size during the head alignment process, avoiding fuzzy positioning of the head clamping mechanism 10 and delaying the alignment time.

[0046] The cylinder section is transported through the transmission mechanism 30. A number of roller tracks 35 arranged in a V shape are provided on the transmission mechanism 30, and the transportation is carried out by the rotation of the roller tracks. The transmission mechanism 30 includes a telescopic roller device 31 and a lifting roller device 32 arranged at intervals. The telescopic roller device 31 includes a set of telescopic rollers 311, a set of telescopic roller frames 312, and a roller telescopic driving device 313. The distance between the telescopic roller frames 312 is adjusted by the roller telescopic driving mechanism 312 to increase or decrease the height of the telescopic rollers 311, so that the telescopic rollers 311 are higher or lower than the roller tracks 35. It should be further noted that the roller telescopic driving device 313 is realized by a lead screw ball or a cylinder. The lifting roller device 32 includes a set of lifting rollers 321, a set of lifting roller frames 322 for installing the lifting rollers 321, and a roller lifting driving device 323. The roller lifting driving device 323 adjusts the height of the lifting roller frames 322 by the elongation and shortening of the hydraulic rod, and then adjusts the height of the lifting rollers 321, so that the lifting rollers 321 are higher or lower than the roller tracks 35. The telescopic roller device 31 is located inside the transmission mechanism 30, and the lifting roller device 32 is located between the head clamping device 11 and the outer end of the transmission mechanism 30. The telescopic roller device 31 and the lifting roller device 32 each include at least a set of rollers arranged symmetrically. The height position of the cylinder section is adjusted by the telescopic roller device 31 and the lifting roller device 32. The telescopic roller device 31 and the lifting roller device 32 do not adopt the same method to adjust the height of the rollers, which is convenient for independently adjusting the height of the cylinder section between the two, more in line with the actual production process. By adjusting the telescopic roller device 31 and the lifting roller device 32, the center line positions of the head and the cylinder are at the same height during the assembly, which is convenient for the assembly. At the same time, according to the rotation device 16, the head and the cylinder section are rotated, driving the rotated rollers in the telescopic roller device 31 and / or the lifting roller device 32 to rotate, so that the head and the cylinder section rotate 360 degrees. On the one hand, it enables the all-round assembly of the cylinder section and the head, and on the other hand, it is convenient for the circumferential welding between the head and the cylinder. In addition, the transmission mechanism 30 further includes a lifting platform 34. The lifting platform 34 is controlled to lift by a hydraulic device 33. The telescopic roller device 31, the lifting roller device 32, and the transmission roller track section 35 located between the two are all arranged on the lifting platform 34, which is convenient for adjusting the height difference between the cylinders of different sizes and the head clamping device 11, so as to facilitate the assembly of the cylinders of different diameters and the head. In addition, during the rotation process, one or two of the telescopic roller device 31 and the lifting roller device 32 are selected to rotate according to the actual situation.

[0047] In order to prevent the cylinder section from shifting on the transmission mechanism 30, the utility model is provided with a gantry-type auxiliary guide mechanism 20, which spans the transmission mechanism 30. The auxiliary guide mechanism 20 includes two vertical beams 21 respectively arranged on both sides of the transmission mechanism 30, a support member 22 supporting the vertical beams 21, a crossbeam device 23, a walking device 24 and a lifting device 25, wherein a crossbeam track 211 of the crossbeam device 23 is arranged on the vertical beam 21, and the crossbeam device 23 moves up and down on the vertical beam 21 through the crossbeam track 211 through the lifting device 25, and according to the diameter of the cylinder section, the height of the crossbeam device 23 is adjusted to meet the transmission of cylinder sections with different diameters. In addition, the crossbeam device 23 includes a slider 231 and a roller-shaped guide member 232 arranged on the slider 231, that is, the roller-shaped guide member 232 can rotate around the axis. After the cylinder section passes through the crossbeam device 23, the height of the crossbeam device 23 is adjusted to the centerline height of the cylinder section. Further, the auxiliary guide mechanism 20 reciprocates on the base 26 through the walking device 24, and then the horizontal position of the crossbeam device 23 can be adjusted, so that the roller-shaped guide member 232 is at the centerline height of the cylinder section to prevent the cylinder section from being displaced between the head clamping mechanism 10 and the auxiliary guide mechanism 20. In addition, during the spot welding process of the cylinder section and the head assembly, by moving the height of the crossbeam device 23 and combining the rotation of the roller-shaped guide member 232, the cylinder can be closely attached to the cylinder body and rotated with the up and down movement of the crossbeam device 23, thereby guiding and pushing the cylinder body. The height of the crossbeam device 23 can also be directly adjusted to make the roller-shaped guide member 232 press the position where the gap between the head and the cylinder body exists, so that the gap between the cylinder body and the head is docked, so that the docking seam where the cylinder body and the head need to be welded is tightly docked, which is convenient for subsequent spot welding.

[0048] The assembly method of a head assembly pair described in the utility model is as follows:

[0049] 1. The cylinder section is transferred to the head assembly table through the transmission mechanism 30;

[0050] 2. According to the diameter of the cylinder section, adjust the crossbeam device 23 to a height that satisfies the normal passage of the cylinder section. After passing through, lower the crossbeam device 23 to the height of the center line of the cylinder;

[0051] 3. The end cap clamping mechanism 10 is in the loading position, the opening size of the clamping teeth 111 is adjusted, the end cap is placed in the clamping 111, and then the position of the buckle 1121 is adjusted, so that the end cap can be clamped and flattened;

[0052] 4. Turn over the end cap clamping mechanism 10 to the working position, adjust the lifting platform 34, the telescopic roller lifting device 31 and the lifting roller device 32 to adjust the height position of the cylinder, and adjust the positioning device 117 to make the height position of the cylinder consistent with the center line of the end cap;

[0053] 5. The auxiliary guiding mechanism 20 moves slowly, and at the same time, the buckle 1121 retracts into the concave rail 1123. The cylinder body is pushed to the clamping teeth 111 through the guiding member 232 for alignment. At this time, the clamping teeth 111 clamp the head and the cylinder body. The disc 115 rotates around the axis through the self-rotation device 16, driving the telescopic roller lifting device 31 and the lifting roller device 32 to rotate, and reaching the welding operation position in sequence at the welding position required at the butt joint to complete the welding;

[0054] 6. During spot welding, the height of the crossbeam device 23 can be adjusted and combined with the auxiliary guiding mechanism 20 to push the cylinder section and the head to reach the welding operation position in sequence after alignment at each point. After welding is completed, the advancing and retracting rod 113 is started to push out the aligned head and cylinder body and transfer them to the next working station;

[0055] 7. The head clamping mechanism 10 retracts to the feeding position of the next head for feeding, and the head clamping device 11 returns to the feeding position through the flipping device 15, and continues to repeat steps 1-6.

[0056] The head alignment and assembly table of the present utility model flattens and fixes the head through the flattening device 112 and the positioning device 114, thereby adjusting the center line position of the head to keep it at the center position of the head clamping device. Combining the adjustment of the center position of the cylinder section by the telescopic roller device 31 and the lifting roller device 32, the center line heights of the head and the cylinder body are made consistent; then, the cylinder section is pushed by the auxiliary guiding mechanism 20 to provide a guiding effect for the alignment of the cylinder body and the head. The self-rotating head clamping mechanism 10 flexibly adjusts the opening of the clamping teeth 111 and the position of the flattening device 112 according to different head sizes to better fix the head; at the same time, the self-rotation device 16 is used to make the disc 115 of the head clamping device 11 rotate self, driving the telescopic roller device 31 and the lifting roller device 32 to rotate, and reaching the welding operation position in sequence at the entire circumference of the butt joint between the head and the cylinder body within 360 degrees to complete the welding. There is no need for manual handling, which is more intelligent, improves work efficiency, and reduces labor costs.

[0057] The above embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
