Description

Technical Field

[0002] Stainless steel pipe is a hollow, long, round steel material, which is widely used in industrial pipelines such as petroleum, chemical, and medical, as well as mechanical structural components. In addition, holes need to be punched when the pipe is used, and accessories need to be installed to facilitate connection with other components to form a complete pipeline. However, the existing device for punching holes in steel pipes is not convenient for supporting the punching position during the punching operation, which can easily cause the stainless steel pipe to bend and become scrapped.

[0003] For example, prior art publication CN212885157U provides a stainless steel pipe drilling and positioning device. The device includes a base plate and a first support plate fixedly connected to the upper surface of the base plate. A first hydraulic pressure is fixedly connected to the lower surface of the first support plate. A first hydraulic rod is provided at the bottom of the first hydraulic pressure. A drilling motor is fixedly connected to the bottom of the first hydraulic rod. A second hydraulic pressure is fixedly connected to the surface of the base plate, directly below the drilling motor. A second hydraulic rod is provided on top of the second hydraulic pressure. This device can make drilling more stable and prevent deviation during drilling.

[0004] While this device has many beneficial effects, it cannot support the drilling position of the stainless steel pipe when drilling. As a result, the drill bit exerts pressure on the steel pipe during rotation, which can easily cause the steel pipe to bend and deform, resulting in scrapping. In view of this, we propose a precise positioning device for stainless steel pipes. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 As shown, a precise positioning device for a stainless steel pipe comprises: a base 1, two sets of clamping and limiting mechanisms 2 are movably mounted above the base 1, a top holding mechanism 3 is disposed between the two sets of clamping and limiting mechanisms 2, and the top holding mechanism 3 is movably connected to the base 1; wherein the clamping and limiting mechanisms 2 include side clamping mechanisms 4 and top clamping mechanisms 5, the side clamping mechanisms 4 and the top clamping mechanisms 5 are disposed in a one-to-one correspondence, and the top clamping mechanism 5 is fixedly mounted above the side clamping mechanisms 4;

[0023] When processing and producing stainless steel pipes, the spacing between the two clamping and limiting mechanisms 2 can be first adjusted according to the length of the stainless steel pipe to be processed, so as to meet the clamping needs of the stainless steel pipe. Then the stainless steel pipe is placed on the clamping and limiting mechanism 2, and the steel pipe is clamped and positioned by adjusting the side clamping mechanism 4 and the top clamping mechanism 5 in the clamping and limiting mechanism 2. In order to ensure that the steel pipe will not be deformed under pressure during processing, the top holding mechanism 3 can be adjusted on the base 1 so that the top holding mechanism 3 is below the position to be processed, supporting the processing position, thereby avoiding the steel pipe from being deformed by force during processing, supporting the stainless steel pipe, and avoiding the problem of the steel pipe being compressed and bent when drilling the steel pipe.

[0024] A chute 101 is provided on the inner side of the base 1. A slider 102 is slidably provided on the inner side of the chute 101. A screw 103 is rotatably provided on the inner side of the chute 101. The screw 103 is connected to the inner side of the slider 102 and the two are connected by a threaded engagement. One end of the screw 103 is connected to a servo motor 104. The clamping and limiting mechanism 2 is fixedly installed on the top of the slider 102, and the screw threads of the sliders 102 installed on the two sets of clamping and limiting mechanisms 2 are arranged in opposite directions.

[0025] A slide groove 101 is provided on the base 1 to facilitate the movement of the slider 102 along the slide groove 101. Since the screw threads of the sliders 102 installed on the two sets of clamping and limiting mechanisms 2 are arranged in opposite directions, the rotation of the servo motor 104 drives the rotation of the screw rod 103. Since the rotation of the screw rod 103 drives the two sliders 102 to move along the slide groove 101, the forward and reverse rotation of the screw rod 103 can drive the two sliders 102 to move closer to or away from each other, thereby driving the two clamping and limiting mechanisms 2 to move closer to or away from each other, thereby realizing the adjustment of the distance between the two clamping and limiting mechanisms 2.

[0026] like Figure 4As shown, the inner side of the base 1 is provided with slots 105 on both sides of the slide 101, and a guide rod 106 is installed in the slot 105, and an adjustment block 107 is sleeved on the guide rod 106; the supporting mechanism 3 includes a top block 301, which is fixedly installed above the adjustment block 107, and a chip collection groove 302 is provided on the inner side of the top block 301, and the chip collection groove 302 is an arc-shaped structure, and a connecting pipe 305 is provided below the chip collection groove 302. A top rod 303 is provided on both sides of the top block 301 with threaded engagement, and a friction plate 304 is connected to the lower end of the top rod 303;

[0027] The slots 105 on the base 1 are convenient for installing the guide rod 106, and the adjusting block 107 can be put on so that the adjusting block 107 can be moved along the guide rod 106 to adjust the position. The supporting mechanism 3 can be adjusted by installing it on the adjusting block 107. The supporting mechanism 3 can be moved to the bottom of the steel pipe processing area to support it according to the needs of the steel pipe processing position. After the supporting mechanism 3 is moved into place, the top rod 303 is extended downward by screwing it, and the friction plate 304 is brought into contact with the base 1, so that The relative position between the supporting mechanism 3 and the base 1 is locked to avoid shaking during use. When the steel pipe is processed, the stainless steel pipe is supported by the top block 301, and the chip collecting groove 302 is located below the processing area, so that the debris generated by the processing can fall into the chip collecting groove 302, and through the arc structure of the chip collecting groove 302, it can flow relatively to the opening connected to the connecting pipe 305, and the other end of the connecting pipe 305 is connected to the dust collecting bag and the vacuum pump to suck away the debris, thereby achieving the purpose of collecting and processing the debris.

[0028] like Figure 2 As shown, the side clamping mechanism 4 includes a guide rail 401, and two sets of sliders 402 are symmetrically slidably provided on the inner side of the guide rail 401. A screw rod 403 is rotatably provided on the inner side of the guide rail 401, and the screw rod 403 and the slider 402 are threadedly engaged. The screw threads in the two sliders 402 have opposite spiral directions. A side clamping piece 404 is installed on the upper end of each slider 402, and one end of the screw rod 403 is connected to a servo motor 405.

[0029] When clamping the steel pipe, the side clamping mechanism 4 can be used to clamp the steel pipe first. First, the steel pipe is placed on the guide rail 401 of the side clamping mechanism 4, and the servo motor 2 405 drives the rotation of the screw rod 2 403. The screw rod 2 403 is engaged with the thread of the slider 2 402, and the screw threads opened in the two sliders 2 402 are set in opposite directions. The two sliders 2 402 can be driven to approach each other along the guide rail 401. The two sliders 2 402 are used to bring the two side clamping pieces 404 close to each other, so that the two side clamping pieces 404 clamp the steel pipe from both sides of the steel pipe.

[0030] like Figure 3 As shown, the top clamping mechanism 5 includes a column 501, which is installed above the two ends of the guide rail 401. A pin 502 is installed on the top of the column 501 on one side. One end of the crossbeam 503 is rotatably connected to the column 501 on one side through the pin 502. The other end of the crossbeam 503 and the column 501 on the other side are respectively provided with a socket 504. The socket 504 is inserted with a pin 505 for limiting the rotation between the column 501 and the crossbeam 503. A telescopic rod 506 is installed in the middle of the crossbeam 503, and the lower end of the telescopic rod 506 is connected to a top clamping piece 507.

[0031] When the steel pipe is clamped and limited, the top clamping mechanism 5 can clamp it from above the steel pipe. When clamping, the top clamping piece 507 is driven to fall by controlling the extension of the telescopic rod 506, and the top clamping piece 507 is used to contact the steel pipe to clamp it from the top. In this way, the steel pipe is clamped up and down, left and right, making the clamping more reliable. When taking and placing the steel pipe, in order to make it easier to take and place the steel pipe and avoid the obstruction of the cross beam 503 and the inconvenience of placing the steel pipe, the pin 502 on the column 501 can be used to rotate the cross beam 503, so that the openings above the two columns 501 are opened, making it convenient to place the steel pipe on the guide rail 401 from top to bottom. When clamping the steel pipe, the cross beam 503 is rotated back, and the pin 505 is inserted into the socket 504 to limit the rotation of the cross beam 503, so that the steel pipe can be better clamped.

[0032] Working principle: when processing and producing stainless steel pipes, the distance between the two clamping and limiting mechanisms 2 can be adjusted first according to the length of the stainless steel pipe to be processed, so as to meet the clamping needs of the stainless steel pipe, and then the stainless steel pipe can be placed on the clamping and limiting mechanism 2, and the steel pipe can be clamped and positioned by adjusting the side clamping mechanism 4 and the top clamping mechanism 5 in the clamping and limiting mechanism 2. In order to ensure that the steel pipe will not be deformed under pressure during processing, the top holding mechanism 3 can be adjusted on the base 1 so that the top holding mechanism 3 is below the position to be processed, and supports the processing position, thereby avoiding the steel pipe from being deformed by force during processing.
