Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe punching, and specifically, it is a steel pipe fixing device for steel pipe punching. Background Art

[0002] Steel pipe punching is usually a common operation during manufacturing or maintenance, used to create one or more holes in a steel pipe. When punching a straight steel pipe, a fixing device is usually used in cooperation with a drilling device to sequentially drill a plurality of holes with equal spacing. The fixing effect of the fixing device is directly related to the accuracy of the holes drilled in the straight steel pipe.

[0003] In the actual device for fixing a steel pipe during punching, for example, the utility model patent with the publication number CN214559245U discloses a fixing device for steel pipe punching. The above solution can effectively prevent the steel pipe from deforming during clamping by clamping and supporting the inner wall of the steel pipe, and it is also convenient to adjust the horizontal movement of the clamped steel pipe, thereby improving the efficiency of steel pipe punching.

[0004] Although the above solution has excellent support and can quickly adjust the position of the steel pipe, during the drilling process, there may be a phenomenon of slipping between the drilling device and the steel pipe, which may lead to 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 drilling. However, the manual cleaning work of the tape is rather cumbersome, and it is difficult to completely remove the tape, resulting in the glue on the tape remaining on the side of the steel pipe, thus affecting the effect of subsequent operations such as spraying on the steel pipe; in addition, since multiple holes need to be drilled during the drilling process, although the above technical solution can adjust the horizontal movement of the clamped steel pipe, it cannot accurately control the spacing between two adjacent drilled holes, which may lead to poor accuracy of the drilled holes. Summary of the Invention

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A steel pipe fixing device for steel pipe drilling, including an installation base plate, on the top of the installation base plate, a horizontal slide rail is fixed. A steel pipe installation mechanism is connected to the horizontal slide rail through a horizontal electric slider. A positioning mechanism located outside the steel pipe installation mechanism is arranged at the middle position of the horizontal slide rail, and a cleaning mechanism is arranged on the right side of the positioning mechanism; The steel pipe installation mechanism includes a moving column installed on the top of the horizontal slider. A horizontal chute is opened at the top of the moving column. A middle plate is fixed in the middle of the horizontal chute.

A motor is installed at the left end of the moving column through a motor box. The output end of the motor is connected to the left end of the bidirectional threaded rod. Moving clamping members are symmetrically threaded on the left and right of the bidirectional threaded rod. The two moving clamping members can achieve the stability of the steel pipe by positioning the two ends of the steel pipe; The positioning mechanism includes connecting members symmetrically arranged before and after at the middle position of the horizontal slide rail. A pressure receiving block is jointly connected to the tops of the two connecting members. The top of the pressure receiving block is an arc-shaped concave surface and is provided with a receiving groove for collecting debris generated during drilling.

[0006] Further, a vertical plate is fixed on the top of the installation base plate and in front of the horizontal slide rail. A first cylinder is installed on the rear side of the vertical plate. The pushing section of the first cylinder is fixed with an outer sleeve block. An inner embedded rod is connected inside the outer sleeve block. A positioning hole and a coordination hole are respectively penetrated through the middle parts of the inner embedded rod and the outer sleeve block. A positioning pin is jointly connected to the coordination hole and the positioning hole. The rear end of the inner embedded rod is fixed with a collection plate. A plurality of blocking plates are horizontally and uniformly fixed on the rear side of the collection plate. The longitudinal lengths of the plurality of blocking plates increase from left to right; A blocked plate is fixed on the front side of the right end of the moving column.

[0007] Further, the moving clamping member includes a moving block threaded on the bidirectional threaded rod. An L-shaped installation plate is fixed on the top of the moving block. A collection column is fixed on the left side of the vertical section of the L-shaped installation plate. A hollow groove is arranged in the middle of the collection column. A plurality of sliding blocks are circumferentially and uniformly slidably connected in the collection column with the hollow groove as the center. One end of each sliding block away from the hollow groove is fixed with an arc-shaped inner abutting plate. A pushing slope is arranged at one end of each sliding block close to the hollow groove. A return spring is connected between the side surface of the sliding block and the side surface of the hollow groove through a spring plate;

[0008] A push rod is horizontally and slidably connected to the middle of the set column and on the right side of the hollow groove. A through rod is fixed to the side of the push rod corresponding to the hollow groove. One end of the through rod located in the hollow groove is fixed with a cross push block for pushing the pushed slope.

[0009] Furthermore, the connecting member includes an L-shaped connecting plate fixed on the horizontal slide rail. A limiting rod is fixed to the top of the vertical section of the L-shaped connecting plate. A sliding plate is slidably connected to the side of the limiting rod. A compression spring is connected between the bottom of the sliding plate and the top of the vertical section of the L-shaped connecting plate.

[0010] Furthermore, the same-direction clamping member includes a second cylinder installed on the side of the vertical section of the L-shaped connecting plate away from the horizontal slide rail. A moving plate is fixed to the pushing end of the second cylinder. Arc-shaped push plates are fixed to the opposite sides of the two moving plates.

[0011] Furthermore, the shoveling member includes a mounting rod fixed in the middle of the collection frame. The bottom of the middle position of the mounting rod is connected to a fixed shovel plate through a first elastic telescopic rod. Rotating rings are symmetrically and rotatably installed on the side of the mounting rod and on the left and right sides of the first elastic telescopic rod. A connecting rod is fixed to the side of the rotating ring and below the collection frame. One end of the connecting rod away from the rotating ring is hinged to a moving shovel plate. Synchronous structures are connected between the tops of the two rotating rings and the same-direction clamping members at the front and rear positions respectively.

[0012] Furthermore, the synchronous structure includes a bent connecting rod fixed to the right side of the same-direction clamping member. One end of the bent connecting rod close to the corresponding rotating ring is hinged to a telescopic rod. The telescopic end of the telescopic rod is fixedly connected to the rotating ring.

[0013] Furthermore, the longitudinal erasing member includes an inner chute provided on the right side of the bottom of the collection frame. A longitudinal slider is slidably connected in the inner chute. The bottom of the longitudinal slider is connected to a cleaning block through a second elastic telescopic rod. Trajectory rods are symmetrically fixed to the front and back of the longitudinal slider; Mounting frames are symmetrically fixed to the front and back of the moving column. The height of the mounting frames is the same as the height of the trajectory rods. A plurality of trajectory protrusions are fixedly inserted through the opposite sides of the two mounting frames. The trajectory protrusions are used to push the trajectory rods and drive the cleaning block to perform reciprocating motion back and forth.

[0014] The beneficial effects of the present invention are as follows: First, the present invention comprehensively cleans the adhesive tape pasted to improve the accuracy of the drilling process and prevent slipping through the cleaning mechanism, and through the shoveling member and the longitudinal erasing member, the adhesive tape is first shoveled up and then the residual glue is removed, so as to comprehensively and effectively remove the adhesive tape and the glue, thereby avoiding the influence of the residual glue on the subsequent spraying and other operation treatment effects of the straight steel pipe. And due to the setting of the second elastic telescopic rod, the cleaning block can continuously press against the side of the straight steel pipe during the reciprocating movement back and forth, thereby increasing the erasing effect of the cleaning block on the glue.

[0015] Second, the present invention uses a baffle to perform multi-stage blocking on the blocked plate, which can precisely control the moving distance of the straight steel pipe during the process of the horizontal electric slider driving the moving column and the moving clamping member to move to the right. Furthermore, each drilling position of the straight steel pipe can be accurately aligned with the drilling device. Moreover, the assembly plate and the baffle can be quickly disassembled and assembled through the coordination holes, outer sleeve blocks, and embedded rods. Therefore, the assembly plate and the baffle can be switched according to the size of the straight steel pipe and the interval of the drilling positions of the straight steel pipe, so as to be applicable to the drilling positions with different spacings on the straight steel pipe.

[0016] Third, the present invention uses a moving clamping member to drive the arc-shaped inner pressing plate to perform inner support on the straight steel pipe after the sliding block is subjected to an outward pressing force, thereby positioning both ends of the straight steel pipe. And the method of performing inner support on the straight steel pipe through the arc-shaped inner pressing plate can adapt to the installation and positioning of straight steel pipes of different sizes. In addition, the pressure-receiving block and the arc-shaped pushing plate can accurately stabilize the drilling position of the straight steel pipe, and can further adapt to straight steel pipes of different sizes. At the same time, the arc-shaped pushing plate can avoid the situation that the straight steel pipe is deformed due to the large stress generated by drilling. BRIEF DESCRIPTION OF THE DRAWINGS

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 Figures 1-2 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, first, the straight steel pipe is installed and positioned by the steel pipe installation mechanism 2. After the installation and positioning are completed, the horizontal electric slider drives the steel pipe installation mechanism 2 to move to the left so that the position to be drilled on the straight steel pipe corresponds to the positions of the positioning mechanism 3 and the drilling device. Subsequently, the operator pastes adhesive tape on the position to be drilled on the straight steel pipe, and then the drilling device drills the straight steel pipe. After drilling is completed, the steel pipe installation mechanism 2 is controlled to drive the straight steel pipe to move to the right again. During the process of the straight steel pipe moving to the right, the cleaning mechanism 4 can comprehensively clean the adhesive tape. Subsequently, the above operations are repeated to achieve the purpose of evenly drilling multiple through holes on the straight steel pipe.

[0031] Refer to Figure 2 、 Figure 3 and Figure 7 As shown in, the steel pipe installation mechanism 2 includes a moving column 21 installed on the top of the horizontal electric slider. A horizontal sliding groove is opened at the top of the moving column 21. A middle plate 211 is fixed in the middle of the horizontal sliding groove. A bidirectional threaded rod 212 is rotatably installed in the middle of the middle plate 211. The left and right ends of the bidirectional threaded rod 212 are respectively connected to the moving column 21 in a penetrating and rotatable manner. A motor 213 is installed at 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. Moving clamping members 22 are symmetrically threaded on the left and right of the bidirectional threaded rod 212. The two moving clamping members 22 can position the two ends of the steel pipe to achieve the stability of the steel pipe.

[0032] The steel pipe installation mechanism 2 is used to position the two ends of the straight steel pipe, so as to drive the straight steel pipe to move, and then control its movement and change its position. At the same time, through the method of positioning at both 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 right moving clamping member 22 is located on the right of the positioning mechanism 3. Subsequently, the operator inserts the straight steel pipe into the positioning mechanism 3 and makes the right end of the straight steel pipe sleeve on the right moving clamping member 22. After the straight steel pipe is sleeved, control the motor 213 to drive 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, they will further fix the position of the straight steel pipe.

[0033] Refer to Figures 2-4, the movable clamping member 22 includes a movable block threadedly connected to the bidirectional threaded rod 212. A vertically arranged L-shaped mounting plate 221 is fixed to the top of the movable block. A collecting column 222 is fixed to 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 collecting column 222. A plurality of sliding blocks 224 are circumferentially and evenly slidably connected in the collecting column 222 with the hollow groove 223 as the center. An arc-shaped inner pressing plate 225 is fixed to one end of each sliding block 224 away from the hollow groove 223. A pushed slope is arranged at one end of each sliding block 224 close to the hollow groove 223. A return spring is connected between the side surface of the sliding block 224 and the side surface 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 on the right side of the hollow groove 223. A through rod 227 is fixed to the side surface of the push rod 226 corresponding to the hollow groove 223. A cross-shaped pushing block 228 for pushing the pushed slope is fixed to 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 pressing plate 225 to perform inner support on the straight steel pipe after the sliding block 224 is subjected to an outward pressing force, so as to position both ends of the straight steel pipe. And by the way that the push rod 226 is pushed by the straight steel pipe to drive the cross-shaped pushing block 228 to press the sliding block 224 outward, the purpose of automatically positioning both ends of the straight steel pipe can be achieved. In addition, by the way that the arc-shaped inner pressing plate 225 performs inner support on the straight steel pipe, the installation and positioning of straight steel pipes with different sizes can be adapted.

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

[0036] Refer to Figures 6-7 , the positioning mechanism 3 includes connecting members 31 symmetrically arranged before and after at the middle position of the horizontal slide rail 11. A pressure receiving block 32 is jointly connected to the tops of the two connecting members 31. The top of the pressure receiving 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 receiving block 32 and on both sides of the receiving groove; The positioning mechanism 3 further 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 to refer to Figures 1-2 , the connecting member 31 includes an L-shaped connecting plate 311 fixed on the horizontal slide rail 11. A limiting rod 312 is fixed at the top of the vertical section of the L-shaped connecting plate 311. A sliding plate 313 is slidably connected to the side of the limiting rod 312. 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 second cylinder 331 installed on the side of the vertical section of the L-shaped connecting plate 311 away from the horizontal slide rail 11. A moving plate 332 is fixed at the pushing end of the second cylinder 331. Arc-shaped pushing 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 position the drilling position, and can also assist in supporting the straight steel pipe with the pressing block 32 during the installation of the straight steel pipe. At the same time, the drilling position of the straight steel pipe can be accurately stabilized through the pressing block 32 and the arc-shaped pushing plate 333, so as to ensure the stability of the drilling position during the welding process of the straight steel pipe, and avoid the situation that the straight steel pipe is deformed due to the large stress generated by drilling.

[0039] Specifically, after the moving clamping member 22 completes the positioning of both ends of the straight steel pipe, control the horizontal electric slider to drive the moving column 21 and the moving clamping member 22 to move to the right, and make the rightmost drilling position on the straight steel pipe correspond to the position of the positioning mechanism 3. At this time, the pressing block 32 will be pressed by the straight steel pipe and support the straight steel pipe downward. Subsequently, control the two second cylinders 331 to drive the arc-shaped pushing plates 333 to support the front and rear positions of the straight steel pipe at the same time, so as to ensure the stability of the drilling position of the straight steel pipe, and the arc-shaped pushing plates 333 continuously push the side of the straight steel pipe during the subsequent movement of the horizontal electric slider driving the moving column 21 and the moving clamping member 22 to the right.

[0040] Refer to Figure 1 and Figure 5 , a vertical plate 12 is fixed on the top of the installation base plate 1 and in front of the horizontal slide rail 11. A first cylinder 121 is installed on the rear side of the vertical plate 12. A sleeve block 122 is fixed at the pushing section of the first cylinder 121. An inner embedded rod 123 is connected inside the sleeve block 122. Positioning holes and coordination holes 124 are respectively arranged through the middle parts of the inner embedded rod 123 and the sleeve block 122. A positioning pin is commonly connected to the coordination hole 124 and the positioning hole. A collecting plate 125 is fixed at the rear end of the inner embedded rod 123. A plurality of blocking plates 126 are horizontally and evenly fixed on the rear side of the collecting plate 125. The longitudinal lengths of the plurality of blocking plates 126 increase from left to right; a blocking plate 127 is fixed on the front side of the right end of the moving column 21.

[0041] By using the baffle 126 to perform multi-stage blocking on the blocked plate 127, during the process of the horizontal electric slider driving the moving column 21 and the moving clamping member 22 to move to the right, the moving distance of the straight steel pipe can be accurately controlled. As a result, each drilling position to be drilled on the straight steel pipe can be accurately aligned with the drilling device. Moreover, the assembly plate 125 and the baffle 126 can be quickly disassembled and assembled through the coordination holes 124, the outer sleeve blocks 122, and the embedded rods 123. Therefore, the assembly plate 125 and the baffle 126 can be switched according to the size of the straight steel pipe and the interval of the drilling positions to be drilled on the straight steel pipe, further increasing the applicability of the present invention.

[0042] Specifically, during the process of controlling the horizontal electric slider to drive the moving column 21 and the moving clamping member 22 to move to the right, the blocked plate 127 will first be blocked by the leftmost baffle 126, so that the drilling position to be drilled on the rightmost side of the straight steel pipe is aligned with the drilling device. Subsequently, control the first cylinder 121 to drive the outer sleeve block 122, the embedded rod 123, and the assembly plate 125 to move forward together, so that all the baffles 126 move forward, and the blocking effect of the leftmost baffle 126 on the blocked plate 127 is released. Then, control the horizontal electric slider to drive the moving column 21 and the moving clamping member 22 to move to the right again and repeat the above operation, so that each drilling position on the straight steel pipe is accurately aligned with the drilling device.

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

[0044] The cleaning mechanism 4 can use the shoveling member 42 to remove the adhesive tape attached to the drilling position of the steel pipe, thus avoiding the situation that the residual adhesive tape affects the appearance and use of the straight steel pipe. At the same time, the longitudinal wiping member 43 can completely remove the glue liquid that cannot be shoveled off and adheres to the side of the straight steel pipe, thereby ensuring the appearance and subsequent normal use of the straight steel pipe.

[0045] Specifically, before the drilling device drills the straight steel pipe, adhesive tape for auxiliary positioning is first pasted at the drilling position. During the process of the horizontal electric slider driving the moving column 21 and the moving clamping member 22 to move to the right, the shoveling member 42 will shovel up the residual adhesive tape and make it fall automatically. After the shoveling is completed, the longitudinal wiping member 43 is used to further remove the glue liquid adhering to the side of the straight steel pipe. And because the longitudinal wiping member 43 moves and wipes longitudinally, the cleaning effect is more comprehensive.

[0046] See also Figures 7-9 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 Figures 7-9 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 erasing member 43 is used to remove the glue remaining on the side of the straight steel pipe with the cleaning block 432, so as to ensure the beauty and subsequent normal use of the straight steel pipe. And by means of the cooperation between the track protrusion 435 and the track rod 433, the cleaning block 432 can move back and forth, and due to the setting of the second elastic telescopic rod, the cleaning block 432 can continuously press against the side of the straight steel pipe during the back-and-forth movement, so as to increase the erasing effect of the cleaning block 432 and improve the comprehensiveness of the cleaning block 432 in erasing the glue.

[0051] Specifically, when the steel pipe installation mechanism 2 finishes installing the straight steel pipe, the straight steel pipe will upwardly press the cleaning block 432 and compress the second elastic telescopic rod. Subsequently, during the process of the horizontal electric slider driving the moving column 21 and the moving 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 sequentially push the track rod 433 during the movement and drive the cleaning block 432 to move back and forth, so as to enable the cleaning block 432 to completely and thoroughly remove the glue remaining on the side of the straight steel pipe.

[0052] In this embodiment, as Figure 9 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 provided at the top of the cleaning block 432, so that the cleaning effect of the cleaning block 432 on the glue is better.

[0053] The working steps of the present invention are as follows: First step, 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 right moving clamping member 22 is located to the right of the positioning mechanism 3. Subsequently, the operator inserts the straight steel pipe into the positioning mechanism 3 and makes the right end of the straight steel pipe sleeved on the right moving clamping member 22. At this time, the straight steel pipe will downwardly press the pressure receiving block 32.

[0054] Second step, after the straight steel pipe is sleeved, control the motor 213 to drive 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, so as to achieve the purpose of positioning the two ends of the straight steel pipe. Subsequently, simultaneously control the two second cylinders 331 to drive the arc-shaped push plates 333 to support the front and rear positions of the straight steel pipe.

[0055] Step 3: After the arc-shaped push plate 333 finishes supporting the front and rear positions of the straight steel pipe, first control the first cylinder 121 to drive the outer sleeve block 122, the embedded rod 123, and the assembly plate 125 to move backward together, so that the leftmost blocking plate 126 can block the blocked plate 127. Subsequently, control the horizontal electric slider to drive the moving column 21 and the moving 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 drilling position to be drilled on the rightmost side of the straight steel pipe is aligned with the drilling device. First, stick the adhesive tape for auxiliary positioning on the drilling position to be drilled, and then control the drilling device to drill the drilling position to be drilled on the rightmost side of the straight steel pipe.

[0056] Step 4: After the drilling device finishes drilling the drilling position to be drilled on the rightmost side of the straight steel pipe, control the first cylinder 121 to drive the outer sleeve block 122, the embedded rod 123, and the assembly 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. Subsequently, control the horizontal electric slider to drive the moving column 21 and the moving clamping member 22 to move to the right again and repeat the above operation, so that each drilling position to be drilled on the straight steel pipe is accurately aligned with the drilling device.

[0057] Step 5: During the process of the horizontal electric slider driving the moving column 21 and the moving clamping member 22 to move to the right, the shoveling member 42 will shovel up the remaining adhesive tape and make it fall automatically. After the shoveling is completed, the longitudinal wiping member 43 is used to further remove the glue adhered to the side of the straight steel pipe, so as to ensure the effect of subsequent operations such as spraying on the drilled straight steel pipe.

[0058] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and still be covered by the protection scope of the present invention.
