Description

Technical Field

[0001] The invention relates to the technical field of steel pipe punching, in particular to a steel pipe fixing device for steel pipe punching. Background Art

[0002] Steel pipe drilling is usually a common operation in the manufacturing or maintenance process, which is used to create one or more holes on the steel pipe. When drilling holes in straight steel pipes, a fixture is usually used in conjunction with a drilling device to drill multiple holes with equal spacing in sequence, and the fixing effect of the fixture is directly related to the accuracy of the holes drilled in the straight steel pipe.

[0003] In the actual device for fixing the steel pipe when punching, there is a utility model patent with publication number CN214559245U that discloses a fixing device for steel pipe punching. The above scheme can effectively prevent the steel pipe from being deformed during the clamping process by clamping and supporting the inner wall of the steel pipe, and can facilitate the lateral movement and adjustment of the clamped steel pipe, thereby improving the efficiency of steel pipe punching.

[0004] Although the above scheme has excellent supporting effect and can quickly adjust the position of the steel pipe, the drilling device and the steel pipe may slip during the drilling process, resulting in poor accuracy of the holes drilled in the straight steel pipe. Therefore, it is necessary to stick auxiliary drilling tape and remove the remaining tape after the drilling is completed. However, the manual cleaning of the tape is cumbersome and difficult to completely remove the tape, resulting in the glue on the tape remaining on the side of the steel pipe, which causes the residual glue to affect the effect of subsequent spraying and other operations on the steel pipe. In addition, since multiple holes need to be drilled during the drilling process, although the above technical solution can perform lateral movement and adjustment of the clamped steel pipe, it is impossible to accurately control the distance between two adjacent drilled holes, resulting in poor accuracy of the drilled holes.

DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0029] See also Figure 1-Figure 2 A steel pipe fixing device for drilling steel pipes comprises a mounting base plate 1, a horizontal slide rail 11 is fixed on the top of the mounting base plate 1, a steel pipe mounting mechanism 2 is connected to the horizontal slide rail 11 through a horizontal electric slider, a positioning mechanism 3 is arranged at the middle position of the horizontal slide rail 11 and is located outside the steel pipe mounting mechanism 2, and a cleaning mechanism 4 is arranged on the right side of the positioning mechanism 3. The present invention installs and positions the straight steel pipe through the steel pipe mounting mechanism 2, and then accurately positions the drilling position through the positioning mechanism 3 and the position of the drilling device, and enables the drilling device to drill holes in multiple positions of the straight steel pipe through the movement of the steel pipe mounting mechanism 2. At the same time, since the drilling device needs to stick adhesive tape on the drilling position during the drilling process, it can avoid the drilling device and the steel pipe from slipping while ensuring the accuracy of drilling holes in the straight steel pipe. The adhesive tape can be fully cleaned through the cleaning mechanism 4, thereby avoiding the situation where the residual adhesive tape affects the appearance and use of the straight steel pipe.

[0030] Specifically, the straight steel pipe is first installed and positioned by the steel pipe installation mechanism 2. After the installation and positioning is completed, the steel pipe installation mechanism 2 is driven to move to the left by the horizontal electric slider so that the position of the straight steel pipe to be drilled corresponds to the position of the positioning mechanism 3 and the drilling device. Then, the operator sticks tape to the position of the straight steel pipe to be drilled, and then the straight steel pipe is drilled by the drilling device. After the drilling is completed, the steel pipe installation mechanism 2 is controlled again to drive the straight steel pipe to move to the right. During the process of the straight steel pipe moving to the right, the cleaning mechanism 4 can completely clean the tape, and then the above operation is repeated, thereby achieving the purpose of evenly drilling multiple through holes on the straight steel pipe.

[0031] See also Figure 2 , Figure 3 and Figure 7 The steel pipe installation mechanism 2 includes a moving column 21 installed on the top of the horizontal electric slider. A horizontal slide groove is opened on the top of the moving column 21. A median plate 211 is fixed in the middle of the horizontal slide groove. A bidirectional threaded rod 212 is rotatably installed in the middle of the median plate 211. The left and right ends of the bidirectional threaded rod 212 are respectively connected to the moving column 21 in a through and rotatable manner. A motor 213 is installed on the left end of the moving column 21 through a motor box. The output end of the motor 213 is connected to the left end of the bidirectional threaded rod 212. The bidirectional threaded rod 212 is symmetrically threaded with moving clamping members 22. The two moving clamping members 22 can be used to position the two ends of the steel pipe to achieve stability.

[0032] The steel pipe installation mechanism 2 is used to position the two ends of the straight steel pipe, so that it can drive the straight steel pipe to move, and then control its movement and change its position. At the same time, by positioning the two ends, the stability of the straight steel pipe during the drilling process can be ensured. Specifically, first control the horizontal electric slider to drive the moving column 21 and the moving clamping member 22 to move to the left, and ensure that the moving clamping member 22 on the right is located on the right side of the positioning mechanism 3. Then, the operator inserts the straight steel pipe into the positioning mechanism 3 and makes the right end of the straight steel pipe be sleeved on the moving clamping member 22 on the right. After the straight steel pipe is sleeved, the control motor 213 drives the bidirectional threaded rod 212 to rotate. At this time, the two moving clamping members 22 will move in the same direction. As the two moving clamping members 22 move, the two will further fix the position of the straight steel pipe.

[0033] See also Figure 2-Figure 4The movable clamping member 22 includes a movable block threadedly connected to the bidirectional threaded rod 212, an L-shaped mounting plate 221 is fixed on the top of the movable block, a collection column 222 is fixed on the left side of the vertical section of the L-shaped mounting plate 221, a hollow groove 223 is arranged in the middle of the collection column 222, and a plurality of sliding blocks 224 are connected in a circumferentially uniformly sliding manner with the hollow groove 223 as the center in the collection column 222, and an arc-shaped inner abutment plate 225 is fixed on the end of each sliding block 224 away from the hollow groove 223, each A push slope is provided at one end of the sliding block 224 close to the hollow groove 223, and a return spring is connected between the side of the sliding block 224 and the side of the hollow groove 223 through a spring plate; a push rod 226 is horizontally slidably connected in the middle of the collecting column 222 and located on the right side of the hollow groove 223, and a through rod 227 is fixed to the side of the push rod 226 corresponding to the hollow groove 223, and a cross pushing block 228 for pushing the pushed slope is fixed at one end of the through rod 227 located in the hollow groove 223.

[0034] The movable clamping member 22 is used to drive the arc-shaped inner support plate 225 to support the straight steel pipe internally after the sliding block 224 is subjected to the outward pressing force, thereby positioning the straight steel pipe at both ends, and the push rod 226 is pushed by the straight steel pipe to drive the cross push block 228 to press the sliding block 224 outward, thereby achieving the purpose of automatically positioning the straight steel pipe at both ends. In addition, the method of supporting the straight steel pipe internally by the arc-shaped inner support plate 225 can adapt to the installation and positioning of straight steel pipes of different sizes.

[0035] Specifically, as the motor 213 drives the bidirectional threaded rod 212 to rotate, the movable clamping member 22 on the right side will drive the straight steel pipe to move to the left. When the straight steel pipe moves to the left and presses against the pushed rod 226 on the left, the straight steel pipe will simultaneously push the pushed rods 226 on both sides outward. As the pushed rods 226 are pushed, the cross pushing block 228 will simultaneously push all the pushed slopes, so that the sliding block 224 and the arc-shaped inner support plate 225 move outward together and provide internal support for the two ends of the straight steel pipe. When the movable clamping member 22 on the right side drives the straight steel pipe to move to the left, the positioning mechanism 3 will provide auxiliary support for the straight steel pipe, thereby ensuring that the straight steel pipe is accurately mounted on the movable clamping member 22 on the left side.

[0036] See also Figure 6-Figure 7 The positioning mechanism 3 includes a connecting member 31 symmetrically arranged in the middle position of the horizontal slide rail 11, and the tops of the two connecting members 31 are commonly connected to a pressure block 32. The top of the pressure block 32 is an arc-shaped concave surface and is provided with a receiving groove for collecting debris generated during drilling. A plurality of evenly arranged balls 321 are symmetrically arranged on the top of the pressure block 32 and on both sides of the receiving groove. The positioning mechanism 3 also includes a same-direction clamping member 33 arranged on the side of each connecting member 31 away from the horizontal slide rail 11.

[0037] Continue reading Figure 1-Figure 2 The connecting member 31 includes an L-shaped connecting plate 311 fixed on the horizontal slide rail 11, a limiting rod 312 is fixed on the top of the vertical section of the L-shaped connecting plate 311, and a sliding plate 313 is slidably connected to the side of the limiting rod 312, and a compression spring is connected between the bottom of the sliding plate 313 and the top of the vertical section of the L-shaped connecting plate 311; the same-direction clamping member 33 includes a No. 2 cylinder 331 installed on the side of the vertical section of the L-shaped connecting plate 311 away from the horizontal slide rail 11, and a moving plate 332 is fixed at the pushing end of the No. 2 cylinder 331, and arc-shaped push plates 333 are fixed on the opposite sides of the two moving plates 332.

[0038] The positioning mechanism 3 is used to cooperate with the drilling device to locate the drilling position, and can also use the pressure block 32 to assist in supporting the straight steel pipe during the installation of the straight steel pipe. At the same time, the pressure block 32 and the arc-shaped push plate 333 can accurately stabilize the drilling position of the straight steel pipe, thereby ensuring that the position of the hole to be drilled is stable during the straight steel pipe welding process, and avoiding the deformation of the straight steel pipe due to the large stress generated by drilling.

[0039] Specifically, after the movable clamping member 22 has completed positioning of both ends of the straight steel pipe, the horizontal electric slider is controlled to drive the movable column 21 and the movable clamping member 22 to move to the right, and make the rightmost position of the hole to be drilled on the straight steel pipe correspond to the position of the positioning mechanism 3. At this time, the pressure block 32 will be pressed down by the straight steel pipe and support the straight steel pipe downward. Subsequently, the two No. 2 cylinders 331 are controlled at the same time to drive the arc push plate 333 to support the front and rear positions of the straight steel pipe, thereby ensuring the stability of the position of the hole to be drilled in the straight steel pipe. In the subsequent process where the horizontal electric slider drives the movable column 21 and the movable clamping member 22 to move to the right, the arc push plate 333 continues to push the side of the straight steel pipe.

[0040] See also Figure 1 and Figure 5 A vertical plate 12 is fixed on the top of the mounting base plate 1 and located in front of the horizontal slide rail 11, a cylinder No. 1 121 is installed on the rear side of the vertical plate 12, a sleeve block 122 is fixed to the pushing section of the cylinder No. 1 121, an embedded rod 123 is connected to the sleeve block 122, and a positioning hole and a matching hole 124 are respectively penetrated in the middle of the embedded rod 123 and the sleeve block 122, and a positioning pin is connected to the matching hole 124 and the positioning hole, a collecting plate 125 is fixed to the rear end of the embedded rod 123, and a plurality of blocking plates 126 are evenly fixed horizontally on the rear side of the collecting plate 125, and the longitudinal lengths of the plurality of blocking plates 126 increase from left to right; a blocked plate 127 is fixed to the front side of the right end of the moving column 21.

[0041] By blocking the blocked plate 127 in multiple stages through the blocking plate 126, the moving distance of the straight steel pipe can be accurately controlled in the process of the horizontal electric slider driving the moving column 21 and the moving clamping member 22 to move to the right, so that each position to be drilled in the straight steel pipe can be accurately aligned with the drilling device, and the collecting plate 125 and the blocking plate 126 can be quickly disassembled and assembled through the matching hole 124, the outer sleeve block 122 and the embedded rod 123, so that the collecting plate 125 and the blocking plate 126 can be switched according to the size of the straight steel pipe and the interval of the positions to be drilled in the straight steel pipe, thereby further increasing the applicability of the present invention.

[0042] Specifically, in the process of controlling the horizontal electric slider to drive the movable column 21 and the movable clamping member 22 to move to the right, the blocked plate 127 will first be blocked by the leftmost blocking plate 126, so that the rightmost position to be drilled in the straight steel pipe is aligned with the drilling device, and then the No. 1 cylinder 121 is controlled to drive the outer sleeve block 122, the embedded rod 123 and the collecting plate 125 to move forward together, so that all the blocking plates 126 move forward and the blocking effect of the leftmost blocking plate 126 on the blocked plate 127 is released, and then the horizontal electric slider is controlled again to drive the movable column 21 and the movable clamping member 22 to move to the right and repeat the above operation, so that each position to be drilled on the straight steel pipe is accurately aligned with the drilling device.

[0043] See also Figure 6-Figure 7 The cleaning mechanism 4 includes a support column 41 fixed on the right side of the connecting member 31, and a collection frame 411 is fixed between the two support columns 41. A scooping member 42 is provided in the middle of the collection frame 411, and a longitudinal wiping member 43 is provided on the right side of the bottom of the collection frame 411. The tape used for auxiliary positioning on the top of the steel pipe is completely removed by first scooping with the scooping member 42 and then wiping with the longitudinal wiping member 43.

[0044] The cleaning mechanism 4 can use the scooping member 42 to remove the tape attached to the position of the steel pipe to be drilled, thereby avoiding the situation where the residual tape affects the appearance and use of the straight steel pipe. At the same time, the glue that cannot be scraped off and adheres to the side of the straight steel pipe can be thoroughly removed through the longitudinal wiping member 43, thereby ensuring the appearance of the straight steel pipe and subsequent normal use.

[0045] Specifically, before the drilling device drills a hole in the straight steel pipe, an auxiliary positioning tape is first pasted at the position to be drilled. When the horizontal electric slider drives the movable column 21 and the movable clamping member 22 to move to the right, the scooping member 42 will scoop up the remaining tape and make it fall automatically. After the shoveling is completed, the glue adhering to the side of the straight steel pipe is further removed by the longitudinal wiping member 43. Since the longitudinal wiping member 43 is in a longitudinal reciprocating motion and cleaning mode, the cleaning effect is more comprehensive.

[0046] See also Figure 7-Figure 9 The scooping member 42 includes a mounting rod 421 fixed to the middle of the assembly frame 411, a fixed shovel plate 422 is connected to the bottom of the middle position of the mounting rod 421 through a No. 1 elastic telescopic rod, a rotating ring 423 is symmetrically installed on the side of the mounting rod 421 and located on the left and right sides of the No. 1 elastic telescopic rod, a connecting rod 424 is fixed to the side of the rotating ring 423 and located below the assembly frame 411, a movable shovel plate 425 is hinged at one end of the connecting rod 424 away from the rotating ring 423, and a synchronization structure is connected between the tops of the two rotating rings 423 and the same-direction clamping members 33 at the front and rear positions respectively; the synchronization structure includes a bending connecting rod 426 fixed to the right side of the same-direction clamping member 33, and a telescopic rod is hinged at one end of the bending connecting rod 426 close to the corresponding position of the rotating ring 423, and the telescopic end of the telescopic rod is fixedly connected to the rotating ring 423.

[0047] The scooping member 42 is used to scrape off the tape with a combination of a fixed shovel plate 422 and a movable shovel plate 425, and due to the staggered positions of the fixed shovel plate 422 and the movable shovel plate 425, the scooped tape can automatically fall from the rear side, and at the same time, the synchronous structure can make the position of the movable shovel plate 425 automatically fit the surface of the straight steel pipe, so as to adapt to straight steel pipes of different sizes for scraping off the tape.

[0048] Specifically, when the same-direction clamping members 33 clamp the front and rear positions of the straight steel pipe, the two bent connecting rods 426 will move in the same direction, and the rotating ring 423 will rotate by pushing the telescopic rod. After the rotating ring 423 completes its rotation, the movable shovel plate 425 will rotate together with the connecting rod 424 and fit against the side of the straight steel pipe. Since the movable shovel plates 425 on the left and right sides are staggered front and back, the two can cooperate with the fixed shovel plate 422 that is pressed upward by the straight steel pipe to remove the tape and make the tape fall off automatically.

[0049] Continue reading Figure 7-Figure 9 The longitudinal erasing component 43 includes an inner slide groove 431 arranged on the right side of the bottom of the collection frame 411, and a longitudinal slider is slidably connected in the inner slide groove 431. The bottom of the longitudinal slider is connected to a cleaning block 432 through a second elastic telescopic rod, and the longitudinal slider is symmetrically fixed with a track rod 433 front and back; the movable column 21 is symmetrically fixed with a mounting bracket 434 front and back, and the height of the mounting bracket 434 is the same as the height of the track rod 433. A plurality of track protrusions 435 are fixedly and interspersed on the opposite sides of the two mounting brackets 434, and the track protrusions 435 are used to push the track rod 433 and drive the cleaning block 432 to reciprocate back and forth.

[0050] The longitudinal wiping component 43 is used to remove the glue remaining on the side of the straight steel pipe with a cleaning block 432, thereby ensuring the beauty of the straight steel pipe and its subsequent normal use, and the cleaning block 432 can reciprocate back and forth through the cooperation between the track protrusion 435 and the track rod 433, and due to the setting of the second elastic telescopic rod, the cleaning block 432 can continue to press against the side of the straight steel pipe during the reciprocating movement back and forth, thereby increasing the wiping effect of the cleaning block 432 and improving the comprehensiveness of the cleaning block 432 in wiping out the glue.

[0051] Specifically, when the steel pipe installation mechanism 2 completes the installation of the straight steel pipe, the straight steel pipe will press the cleaning block 432 upward and compress the second elastic telescopic rod. Subsequently, when the horizontal electric slider drives the movable column 21 and the movable clamping member 22 to move to the right, the mounting frame 434 and the track protrusion 435 will move to the right synchronously, and the track protrusions 435 at the front and rear positions will push the track rod 433 in turn during the movement and drive the cleaning block 432 to move back and forth, so that the cleaning block 432 can completely remove the glue remaining on the side of the straight steel pipe.

[0052] In this embodiment, if Fig. 9 As shown, the cleaning block 432 is made of sponge material and is an arc-shaped plate. At the same time, a glue remover supply unit for automatically dripping the glue remover is arranged on the top of the cleaning block 432, so that the cleaning block 432 has a better effect on removing glue.

[0053] The working steps of the present invention are as follows: the first step is to control the horizontal electric slider to drive the movable column 21 and the movable clamping member 22 to move to the left, and ensure that the movable clamping member 22 on the right side is located on the right side of the positioning mechanism 3. Then the operator inserts the straight steel pipe into the positioning mechanism 3 and makes the right end of the straight steel pipe be sleeved on the movable clamping member 22 on the right side. At this time, the straight steel pipe will press downward on the pressure block 32.

[0054] In the second step, after the straight steel pipe is installed, the control motor 213 drives the bidirectional threaded rod 212 to rotate. At this time, the two movable clamping components 22 will move in the same direction. As the two movable clamping components 22 move, the two will further fix the position of the straight steel pipe, thereby achieving the purpose of positioning the two ends of the straight steel pipe. Then, the two No. 2 cylinders 331 are controlled at the same time to drive the arc push plate 333 to support the front and rear positions of the straight steel pipe.

[0055] The third step is to wait for the arc-shaped push plate 333 to complete supporting the front and rear positions of the straight steel pipe, first control the No. 1 cylinder 121 to drive the outer sleeve block 122, the embedded rod 123 and the collecting plate 125 to move backward together, so that the leftmost blocking plate 126 can block the blocked plate 127, and then control the horizontal electric slider to drive the moving column 21 and the moving clamping member 22 to move to the right, and the blocked plate 127 will first be blocked by the leftmost blocking plate 126, so that the rightmost position to be drilled in the straight steel pipe is aligned with the drilling device, first a tape for auxiliary positioning is applied to the position to be drilled, and then the drilling device is controlled to drill the rightmost position to be drilled in the straight steel pipe.

[0056] The fourth step, when the drilling device completes drilling the rightmost position to be drilled in the straight steel pipe, control the No. 1 cylinder 121 to drive the outer sleeve block 122, the embedded rod 123 and the collecting plate 125 to move forward together, so that all the blocking plates 126 move forward, and release the blocking effect of the leftmost blocking plate 126 on the blocked plate 127, then control the horizontal electric slider again to drive the moving column 21 and the moving clamping member 22 to move to the right and repeat the above operation, so that each position to be drilled on the straight steel pipe is accurately aligned with the drilling device.

[0057] In the fifth step, when the horizontal electric slider drives the movable column 21 and the movable clamping member 22 to move to the right, the scooping member 42 will scoop up the remaining tape and make it fall automatically. After the shoveling is completed, the glue adhering to the side of the straight steel pipe is further removed by the longitudinal wiping member 43, thereby ensuring the effect of subsequent spraying and other operations on the drilled straight steel pipe.

[0058] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
