Description

Technical Field

[0001] The invention relates to the technical field of welding clamping tools, and more specifically to a welding clamping tool for a perforator magazine tube. Background Art

[0002] The perforator clip tube is the main component of the perforator used in the oil industry. The tubing-transported perforator is referred to as TCP. The basic principle of tubing-transported perforator is to connect all the perforators of the oil and gas layers to be perforated in each well in series, connect them to the tail end of the tubing string, form a hard-connected pipe string and lower it into the well. By measuring the radioactive curve or magnetic positioning curve in the tubing, calibrating the depth and aligning the perforating layer, a variety of detonation methods can be used to detonate the perforator. The perforator is mainly composed of an outer tube, a clip tube, bullets and connecting parts, among which the clip tube is the main accessory. The international mainstream uses special customized laser cutting equipment for processing. The product length can be up to 10 meters, and most of them are more than 6 meters. About 120-200 holes need to be processed on the 6-meter specification for subsequent loading. Each hole is a special-shaped hole, which requires high precision and needs to be tested. The phase angle and distance accuracy requirements between holes are very high.

[0003] The shortcomings of the existing technology: when processing the magazine tube of the perforator, it is necessary to weld magazine tube plugs on the front and rear ends of the magazine tube. Since the length of the magazine tube is generally between 6 and 10 meters, the existing clamping tooling is difficult to meet the clamping effect of magazine tubes of different sizes. Moreover, during welding, the magazine tube plugs are generally buckled on both ends of the magazine tube manually, which makes it difficult to accurately position the magazine tube plugs, which will affect the accuracy of the welding of the magazine tube plugs. For this reason, we propose a clamping tool for welding the magazine tube of the perforator. Summary of the invention

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures recorded in the following embodiments are only examples. The clamping tool for welding the perforator magazine tube involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0029] like Figure 1-11As shown, in one embodiment, a clamping tool for welding a magazine tube of a perforator is proposed, including a machine base 1, an adjustment groove 101 is opened on both sides of the front and rear ends of the upper end of the machine base 1, a first adjustment seat 2 and a second adjustment seat 3 are slidably connected in the adjustment groove 101, a clamping seat 4 is fixedly connected to the upper ends of the machine base 1 and the first adjustment seat 2 and the second adjustment seat 3, a clamping mechanism 5 is arranged in the clamping seat 4, a magazine tube body 6 is clamped in the clamping seat 4 by the clamping mechanism 5, a rotating seat 201 is rotatably connected in the first adjustment seat 2 through a rotating shaft, a plurality of guide rods 7 are slidably connected in the rotating seat 201 and the second adjustment seat 3, a lifting seat 701 is fixedly connected to the upper end of the guide rod 7, a positioning mechanism 8 and a welding mechanism 9 are arranged on the surface of the lifting seat 701, the positioning mechanism 8 includes a first fixedly connected to the upper end of the lifting seat 701 A support plate 801, a first cylinder 802 is fixedly connected to the surface of the first support plate 801, an output end of the first cylinder 802 is slidably connected to the first support plate 801, a bearing 803 is fixedly connected to the output end of the first cylinder 802, a positioning head 804 is fixedly connected to the outer surface of the bearing 803, the positioning head 804 is conical, a guide plate 805 is fixedly connected to the circumferential surface of the positioning head 804, a support rod 806 is slidably connected inside the guide plate 805, a magnetic block 807 is fixedly connected to the end of the support rod 806 away from the guide plate 805, a spring 808 is fixedly connected between the magnetic block 807 and the guide plate 805, a magazine tube plug 601 is attracted to the surface of the magnetic block 807, the positioning head 804 penetrates the magazine tube plug 601, and a welding mechanism is used to weld the magazine tube plug 601 to the magazine tube body 6.

[0030] In actual application, the embodiment of the present invention can adjust the front and rear positions of the first adjustment seat 2 and the second adjustment seat 3 in the adjustment slot 101 according to the length of the magazine tube body 6, thereby changing the position movement of the clamping seat 4 on the front and rear sides, and realizing synchronous adjustment of the front and rear positions of the positioning mechanism 8 and the welding mechanism 9, so as to adapt to the size of the magazine tube body 6 to be welded, so that the length of the magazine tube body 6 is the same as the distance between the welding gun heads 903 in the welding mechanisms 9 on the front and rear sides. When loading is required, the rotating seat 201 is controlled to rotate downward, and the parts on the rotating seat 201 will rotate downward so that it will not block the front end of the machine base 1. At this time, the magazine tube body 6 can be moved from the front to the rear in the clamping seat 4. Push, and then complete the loading operation, then under the action of the clamping mechanism 5, the magazine tube body 6 in the clamping seat 4 is clamped and positioned, and driven. After the loading is completed, the rotating seat 201 is controlled to reset, so that the positioning mechanism 8 and the welding mechanism 9 on the rotating seat 201 are reset, and then the magazine tube plug 601 is attached to the magnetic block 807 under the action of magnetic force, and then the first cylinder 802 on both sides is controlled to operate, and the output end of the first cylinder 802 will drive the positioning head 804 to move inward, so that the magazine tube plug 601 adsorbed by the magnetic block 807 at the front end of the support rod 806 moves to the end face of the magazine tube body 6, and then the positioning head 804 is controlled to continue to move toward the direction of the magazine tube body 6. Under the action of the spring 808, the support rod 806 and the magnetic block 807 will push the magazine tube plug 601 to fit with the magazine tube body 6 on all sides, ensuring that the magazine tube plug 601 and the magazine tube body 6 fit tightly, and then the positioning head 804 will pass through the through hole in the middle of the magazine tube plug 601. Since the positioning head 804 is conical, it can cooperate with the through hole in the middle of the magazine tube plug 601 to correct the position of the magazine tube plug 601, so that the center of the magazine tube plug 601 coincides with the center of the magazine tube body 6, which can avoid the magazine tube plug 601 and the magazine tube body 6 from being misaligned around the four sides, thereby improving the accuracy of the magazine tube plug 601 and the magazine tube body 6 when fitting. When 503 rotates, the magazine tube body 6 can be driven to rotate. At the same time, through the action of the bearing 803, the friction at the connection between the positioning head 804 and the output end of the first cylinder 802 can be reduced. When the magazine tube body 6 rotates, it will simultaneously drive the magazine tube plug 601 that is in contact with the end surface of the magazine tube body 6 and the positioning head 804 that resists the magazine tube plug 601 to rotate. Then, through the action of the welding mechanism 9, the magazine tube body 6 and the magazine tube plug 601 can be welded and fixed. After the welding is completed, the welding mechanism 9, the positioning mechanism 8 and the clamping mechanism 5 are reset, and then the rotating seat 201 is controlled to rotate again, and the front end of the machine base 1 is opened, so that the magazine tube body 6 in the clamping seat 4 can be pulled out from the front to complete the unloading.

[0031] In one embodiment of the present invention, the height position of the center point of the welding gun head 903 and the center point of the positioning head 804 in the device is always the same.

[0032] like Figure 5 and 6 As shown, as a preferred embodiment of the present invention, a first motor 10 is fixedly connected to the lower end of the machine base 1, a driving shaft 1001 is fixedly connected to the output end of the first motor 10, a bidirectional threaded rod 1002 is rotatably connected inside the machine base 1, a circumferential surface of the bidirectional threaded rod 1002 is threadedly connected to the first adjustment seat 2 and the second adjustment seat 3, a first sprocket 1003 is fixedly connected to the circumferential surface of the driving shaft 1001, a second sprocket 1004 is fixedly connected to the circumferential surface of the bidirectional threaded rod 1002, and the first sprocket 1003 and the second sprocket 1004 are connected by a first chain.

[0033] In actual application, the embodiment of the present invention controls the operation of the first motor 10, and the first motor 10 drives the bidirectional threaded rod 1002 to rotate through the action of the driving shaft 1001, the first sprocket 1003, the first chain and the second sprocket 1004. When the bidirectional threaded rod 1002 rotates, it drives the first adjustment seat 2 and the second adjustment seat 3 on the front and rear sides to slide in the adjustment groove 101 in mutual directions, thereby achieving the effect of adjusting the distance between the clamping seats 4 on the front and rear sides, so that the equipment can meet the requirements of clamping, positioning and welding of magazine tube bodies 6 of different lengths.

[0034] like Figure 8 As shown, as another preferred embodiment of the present invention, a first support block 202 is fixedly connected to the lower end of the base 1, a second support block 203 is fixedly connected to the lower end of the rotating base 201, a second cylinder 204 is rotatably connected inside the first support block 202, and an output end of the second cylinder 204 is rotatably connected to the second support block 203.

[0035] When the embodiment of the present invention is actually applied, by controlling the operation of the second cylinder 204, the second cylinder 204 will drive the rotating base 201 to rotate under the action of the second support block 203, thereby achieving the effect of opening the space in front of the base 1, avoiding mechanical parts from blocking the front of the base 1, and facilitating the loading and unloading of the magazine tube body 6.

[0036] In one embodiment of the present invention, Figure 7 and 8 As shown, a limiting block is provided on the inner wall of the first adjustment seat 2 in the device, and a limiting groove is provided on the upper end surface of the rotating seat 201. Through the action of the limiting block and the limiting groove, the maximum upward rotation angle of the rotating seat 201 can be limited, so that the rotating seat 201 is flush with the first adjustment seat 2 when it is reset upward.

[0037] like Fig. 9As shown, as another preferred embodiment of the present invention, the upper end of the lifting seat 701 is fixedly connected to the second support plate 11, the surface of the second support plate 11 is fixedly connected to the third cylinder 1101, the output end of the third cylinder 1101 is slidingly connected to the second support plate 11, the output end of the third cylinder 1101 is fixedly connected to the limit plate 1102, and the limit plate 1102 is used to limit the loading of the magazine tube body 6.

[0038] When the embodiment of the present invention is actually applied, by controlling the operation of the third cylinder 1101, the output end of the third cylinder 1101 will drive the limit plate 1102 to extend. When the magazine tube body 6 is loaded, the limit position of the magazine tube body 6 moving backward can be blocked. When the rear end of the magazine tube body 6 contacts the limit plate 1102, it means that the loading position of the magazine tube body 6 is basically within the appropriate range. Then, the magazine tube body 6 can be clamped and positioned by controlling the clamping mechanism 5. Then, the output end of the third cylinder 1101 is reset by controlling the output end to drive the limit plate 1102 to retract, so as to avoid affecting the subsequent magazine tube plug 601 and the magazine tube body 6.

[0040] In actual application, when the embodiment of the present invention is located in the clamping seat 4, the fourth cylinder 506 is controlled to operate, and the fourth cylinder 506 drives the connecting arm 508 to rotate with the second rotating seat 505 as the center, thereby driving the second rotating frame 5010 to rotate, so that the driven roller 5011 connected to the second rotating frame 5010 by the rotating shaft can clamp the magazine tube body 6 from the upper oblique direction, and then cooperate with the active roller 503 to achieve the effect of clamping and positioning the magazine tube body 6, and can also clamp magazine tube bodies 6 of different diameters. At the same time, under the action of the roller 5013 rotatably connected in the active roller 503 and the driven roller 5011, when the magazine tube body 6 is loaded on the active roller 503, the magazine tube body 6 is clamped on the active roller 5011. 3, the magazine tube body 6 and the roller 5013 in the active roller 503 can slide, so that the friction can be reduced during loading and unloading, making loading and unloading more convenient and labor-saving. At the same time, after the magazine tube body 6 is clamped and positioned, when the positioning mechanism 8 is running, the positioning heads 804 on the front and rear sides squeeze the magazine tube body 6 through the magazine tube plug 601. At this time, under the action of the roller 5013 again, the front and rear position of the magazine tube body 6 can slide on the roller 5013, so as to achieve accurate front and rear position positioning of the magazine tube body 6, correct the front and rear position of the magazine tube body 6, so that the welding head can be aligned with the joint between the magazine tube body 6 and the magazine tube plug 601, thereby improving the accuracy of welding.

[0044] In actual application, the embodiment of the present invention controls the sixth cylinder 702 to operate. Under the action of the guide rod 7, the lifting seat 701 is driven to adjust the upper and lower positions. When the diameters of the magazine tube body 6 clamped in the clamping mechanism 5 are different, the position of the lifting seat 701 can be adjusted to make the welding gun head 903 in the welding mechanism 9 and the center of the magazine tube body 6 have the same height, and make the positioning head 804 in the positioning mechanism 8 and the center of the magazine tube body 6 concentric, thereby achieving the effect of being able to adapt to the welding processing of magazine tube bodies 6 with different diameters.
