Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe processing technology, and more specifically, to an adjustable drilling device for corrugated pipes. Background Technology

[0002] Corrugated pipes on the market are all produced using extrusion molding. During extrusion molding, it's impossible to machine the holes required for production standards onto the pipe surface. Because there's a lack of specialized pipe drilling equipment on the market, holes are typically drilled manually using electric drills. Furthermore, the lack of accurate positioning during manual drilling results in holes with insufficient precision in spacing and angle, failing to meet product quality requirements.

[0003] Patent CN106272689A discloses a corrugated pipe drilling device, including a work plate, an electric drill and a drill drive device mounted on the work plate. The work plate has a through hole for inserting the corrugated pipe, and the drill bit direction of the electric drill is consistent with the radial direction of the through hole. The drill drive device is connected to the electric drill and is used to drive the electric drill forward or backward. The drill bit direction of this invention is consistent with the radial direction of the corrugated pipe, thereby enabling radial machining of circular holes in double-walled or single-walled corrugated pipes. At least two sets of electric drills and drill drive devices are evenly distributed on the work plate. However, in the above solution, there is no accurate positioning tool, and the machining accuracy may be insufficient. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology in the absence of positioning tools, and to provide an adjustable drilling device for bellows, which can accurately fix the bellows in a suitable drilling position.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An adjustable drilling device for a corrugated pipe is provided, comprising a mounting frame, a controller, a drilling mechanism, a clamping mechanism for clamping and positioning the corrugated pipe, and a first sensor for sensing the position of the corrugated pipe trough. The clamping mechanism and the drilling mechanism are both mounted on the mounting frame, and the first sensor, the clamping mechanism, and the drilling mechanism are all connected to the controller.

[0007] The adjustable drilling device for corrugated pipes of this invention moves the corrugated pipe until the first sensor indicates that the trough of the corrugated pipe has reached the position of the drilling mechanism. The first sensor transmits a signal to the controller, which controls the clamping mechanism to clamp the corrugated pipe and controls the drilling mechanism to start drilling. Through the cooperation of the first sensor and the clamping mechanism, the corrugated pipe can be accurately fixed in the appropriate drilling position with high drilling accuracy.

[0008] Furthermore, the first sensor is a through-beam sensor, comprising a transmitter and a receiver, both mounted on the drilling mechanism. The receiver is connected to the controller. The ray emitted by the transmitter is perpendicular to the axis of the bellows, and the distance between the ray emitted by the transmitter and the axis of the bellows is greater than the radius of the trough but less than the radius of the crest. Because the distance between the ray emitted by the transmitter and the axis of the bellows is greater than the radius of the trough but less than the radius of the crest, when the receiver receives the ray from the transmitter, the trough is located between the transmitter and the receiver; when the receiver does not receive the ray from the transmitter, the ray is blocked by the trough, which is located between the transmitter and the receiver.

[0009] Furthermore, a second sensor is included to sense the arrival of the bellows at the drilling station. This second sensor is mounted on the mounting bracket and connected to the controller. When the bellows moves to the drilling station, the second sensor sends a signal to the controller. The controller then controls the clamping mechanism to clamp the bellows, and then releases the clamping mechanism. The bellows continues to move until the first sensor senses a trough. The controller then controls the clamping mechanism to clamp the bellows again to begin drilling. Through the cooperation of the second sensor and the clamping mechanism, the bellows is initially positioned, preventing excessive deviation between the bellows' position and the drilling mechanism's position, which could cause the first sensor to fail to accurately sense the trough position.

[0010] Furthermore, the drilling mechanism includes a mounting plate, a first driving device, and an electric drill. The mounting plate has a through hole through which the corrugated pipe passes. The first driving device is mounted on the mounting plate, and its output end is connected to the electric drill. The driving direction of the first driving device, the direction of the electric drill bit, and the diameter direction of the corrugated pipe coincide. Both the transmitting end and the receiving end are mounted on the mounting plate. After the corrugated pipe is moved to a suitable drilling position, the first driving device drives the electric drill to move towards the corrugated pipe. The electric drill drills a hole in the corrugated pipe. Since the driving direction of the first driving device and the direction of the electric drill bit coincide with the diameter direction of the corrugated pipe, the axial direction of the hole drilled by the electric drill in the corrugated pipe coincides with the diameter of the corrugated pipe.

[0011] Furthermore, the mounting plate is provided with a linear guide rail, on which a slider is slidably mounted. The electric drill is fixedly mounted on the slider, and the slider is connected to the output end of the first driving device. When the drilling mechanism is working, the first driving device drives the slider to move along the linear guide rail toward the bellows, thereby moving the electric drill toward the bellows.

[0012] Furthermore, the clamping mechanism includes two sets of clamping blocks and a second driving device that drives the two sets of clamping blocks to move towards each other. The clamping blocks are fixedly connected to the output end of the second driving device. The two sets of second driving devices drive in opposite directions and are perpendicular to the axis of the bellows. The controller is connected to the second driving device. When the first sensor detects that the bellows has reached the drilling position, it transmits a signal to the controller. The controller controls the second driving device to drive the two sets of clamping blocks to move towards each other, and the two sets of clamping blocks clamp the bellows, thus fixing the bellows.

[0013] Furthermore, the mounting plate is equipped with two or more electric drills and two or more of the first drive devices. The mounting plate being equipped with two or more electric drills and the first drive devices allows for the simultaneous drilling of multiple holes at the same axial position on the bellows.

[0014] Furthermore, the mounting bracket is provided with two or more drilling mechanisms, each arranged along the axial direction of the bellows. Providing two or more drilling mechanisms allows for simultaneous drilling at different positions along the axial direction of the bellows, improving drilling efficiency.

[0015] Furthermore, the device also includes an adjustment mechanism for adjusting the horizontal distance between the drilling mechanisms. This adjustment mechanism is mounted on the mounting bracket and connected to the drilling mechanisms. When drilling different corrugated pipes, the distance between each hole along the corrugated pipe axis may vary; for example, different spacing between corrugation troughs can lead to different hole spacings. By adjusting the horizontal position of the drilling mechanisms using the adjustment mechanism, the distance between each drilling mechanism is changed, thus adjusting the drilling spacing. This ensures that when one drilling mechanism reaches its drilling position, the other drilling mechanisms also reach the correct drilling position, increasing the applicability of this device to different pipe materials.

[0016] Furthermore, the adjustment mechanism includes a lead screw, a lead screw support, a third drive device for driving the lead screw to rotate, and a guide mechanism for restricting the horizontal movement of the drilling mechanism. The lead screw support is fixed to the mounting frame, and the lead screw is rotatably connected to the lead screw support. The drilling mechanism has a screw hole that mates with the lead screw, through which the lead screw passes. The guide mechanism is fixedly mounted on the mounting frame and connected to the drilling mechanism. When the adjustment mechanism is working, the third drive device drives the lead screw to rotate. Because the guide mechanism restricts the direction of movement of the drilling mechanism, the drilling mechanism cannot rotate with the lead screw. The lead screw drives the drilling mechanism to move horizontally through the screw hole, thereby adjusting the position of the drilling mechanism.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] The adjustable drilling device for corrugated pipes of this utility model has the following features: 1. It can accurately fix the corrugated pipe in a suitable drilling position by using the cooperation of a first sensor and a clamping mechanism according to the drilling needs; 2. It can set two or more drilling mechanisms along the axial direction of the corrugated pipe, and can drill holes at different axial positions of the corrugated pipe at the same time; 3. The adjustment mechanism can adjust the horizontal position of each drilling mechanism, change the distance between each drilling mechanism, and adjust the drilling spacing, thereby increasing the applicability of the equipment to different pipe materials.

[0027] Example 1

[0028] like Figures 1 to 5 The first embodiment of the adjustable drilling device for corrugated pipe of this utility model is shown, including a mounting frame 6, a controller, a drilling mechanism 1, a clamping mechanism 2 for clamping and positioning the corrugated pipe 7, and a first sensor 3 for sensing the position of the corrugated pipe 7 trough. The clamping mechanism 2 and the drilling mechanism 1 are both mounted on the mounting frame 6, and the first sensor 3, the clamping mechanism 2 and the drilling mechanism 1 are all connected to the controller.

[0029] This utility model discloses an adjustable drilling device for corrugated pipes. The corrugated pipe 7 is moved until the first sensor 3 indicates that the trough of the corrugated pipe 7 has reached the position of the drilling mechanism 1. The first sensor 3 transmits a signal to the controller, which then controls the clamping mechanism 2 to clamp the corrugated pipe 7, and the drilling mechanism 1 begins drilling. Through the cooperation of the first sensor 3 and the clamping mechanism 2, the corrugated pipe 7 can be accurately fixed in a suitable drilling position, resulting in high drilling accuracy. In this embodiment, the controller is a PLC.

[0030] like Figure 1 , Figure 2 and Figure 5 As shown, the first sensor 3 is a through-beam sensor, comprising a transmitter 31 and a receiver 32. Both transmitter 31 and receiver 32 are mounted on the drilling mechanism 1. Receiver 32 is connected to the controller. The ray emitted by transmitter 31 is perpendicular to the axis of bellows 7. The distance between the ray emitted by transmitter 31 and the axis of bellows 7 is greater than the radius of the trough of bellows 7 but less than the radius of the crest of bellows 7. Because the distance between the ray emitted by transmitter 31 and the axis of bellows 7 is greater than the radius of the trough but less than the radius of the crest, when receiver 32 receives the ray emitted by transmitter 31, the trough is located between transmitter 31 and receiver 32. When receiver 32 does not receive the ray emitted by transmitter 31, the ray is blocked by the trough, which is located between transmitter 31 and receiver 32.

[0031] like Figure 2 and Figure 5 As shown, it also includes a second sensor 4 for sensing the arrival of the bellows 7 at the work station. The second sensor 4 is mounted on the mounting bracket 6 and connected to the controller. When the bellows 7 moves to the drilling work station, the second sensor 4 transmits a signal to the controller. The controller controls the clamping mechanism 2 to clamp the bellows 7, and then releases the clamping mechanism 2 to continue moving until the first sensor 3 senses the trough. The controller then controls the clamping mechanism 2 to clamp the bellows 7 again to perform the drilling operation. Through the cooperation of the second sensor 4 and the clamping mechanism 2, the bellows 7 is initially positioned to prevent the position of the bellows 7 from deviating too much from the position of the drilling mechanism 1, which would cause the first sensor 3 to fail to accurately sense the trough position.

[0032] like Figure 1 As shown, it also includes a pipe support frame 8 for supporting the corrugated pipe 7. During the start-up process of the corrugated pipe 7, the corrugated pipe 7 is placed on the pipe support frame 8. The pipe support frame can keep the height of the corrugated pipe constant during the movement, reducing the coaxiality error of the corrugated pipe 7.

[0033] The working principle of the adjustable drilling device for the corrugated pipe in this embodiment is as follows: When performing the opening operation of the corrugated pipe 7, the corrugated pipe 7 is placed on the pipe support frame 8, and the corrugated pipe 7 is moved to the drilling position. The second sensor 4 transmits a signal to the controller, and the controller controls the clamping mechanism 2 to clamp the corrugated pipe 7. Then the clamping mechanism 2 is released, and the corrugated pipe 7 continues to move until the ray from the transmitting end 31 is received by the receiving end 32, indicating that the trough of the corrugated pipe 7 has reached the position of the drilling mechanism 1. The receiving end 32 transmits a signal to the PLC controller, and the controller controls the clamping mechanism 2 to clamp the corrugated pipe 7. The drilling mechanism 1 drills a hole in the corrugated pipe 7. Then the clamping mechanism 2 releases the corrugated pipe 7, the drilling mechanism 1 stops, and the corrugated pipe 7 continues to move. When the receiving end 32 receives the signal from the transmitting end 31 again, the clamping mechanism 2 clamps the corrugated pipe 7 again, and the drilling mechanism 1 performs drilling. The above steps are repeated until the opening operation of the corrugated pipe 7 is completed.

[0034] Example 2

[0035] This embodiment is the second embodiment of the adjustable drilling device for the corrugated pipe of this utility model. This embodiment is similar to the first embodiment, except that the drilling mechanism 1 includes a mounting plate 11, a first driving device 12 and an electric drill 13. The mounting plate 11 is provided with a through hole for the corrugated pipe 7 to pass through. The first driving device 12 is mounted on the mounting plate 11. The output end of the first driving device 12 is connected to the electric drill 13. The driving direction of the first driving device 12, the direction of the drill bit 132 of the electric drill 13 and the diameter direction of the corrugated pipe 7 coincide. The transmitting end 31 and the receiving end 32 are both mounted on the mounting plate 11. After the bellows 7 is moved to a suitable drilling position, the first drive device 12 drives the electric drill 13 to move towards the bellows 7. The electric drill 13 drills a hole in the bellows 7. Since the driving direction of the first drive device 12 and the direction of the drill bit 132 of the electric drill 13 coincide with the diameter direction of the bellows 7, the axial direction of the hole drilled by the electric drill 13 on the bellows 7 coincides with the diameter of the bellows 7, ensuring that the hole is flat and vertical. In this embodiment, the suitable drilling position is the position of the bellows 7 when the electric drill 13 is aligned with the bottom of the bellows trough.

[0036] like Figure 3 As shown, a linear guide rail 14 is provided on the mounting plate 11, and a slider 15 is slidably mounted on the linear guide rail 14. The electric drill 13 is fixedly mounted on the slider 15, and the slider 15 is connected to the output end of the first driving device 12. When the drilling mechanism 1 is working, the first driving device 12 drives the slider 15 to move along the linear guide rail 14 toward the bellows 7, thereby driving the electric drill 13 to move toward the bellows 7.

[0037] like Figure 3 As shown, a guide rail fixing seat 16 is installed on the mounting plate 11. The guide rail fixing seat 16 has an L-shaped plate structure. The linear guide rail 14 is installed on the horizontal side of the guide rail fixing seat 16. The output end of the first drive device 12 passes through the vertical side of the guide rail fixing seat 16. The first drive device 12 is a cylinder. The electric drill 13 includes a brushless motor 131 and a drill bit 132. The drill bit 132 is fixedly connected to the output end of the brushless motor 131. An L-shaped fixing plate 133 is installed on the slider 15. The brushless motor 131 is fixedly installed on the horizontal side of the L-shaped fixing plate 133. The drill bit 132 passes through the side of the L-shaped fixing plate 133 that is perpendicular to the mounting plate 11. A Y-connector 121 is provided on the output end of the cylinder. The L-shaped fixing plate 133 is fixedly installed on the Y-connector 121. When the drilling mechanism 1 is working, the cylinder pushes the L-shaped fixing plate 133 through the Y-joint 121, so that the L-shaped fixing plate 133 slides on the linear guide rail 14 along with the slider 15 fixed at its bottom, thereby driving the electric drill 13 to slide on the linear guide rail 14. When the drill bit 132 comes into contact with the bellows 7, the brushless motor 131 drives the drill bit 132 to rotate and drill holes in the bellows 7.

[0038] like Figure 1 and Figure 2As shown, the clamping mechanism 2 includes two sets of clamping blocks 22 and a second drive device 21 that drives the two sets of clamping blocks 22 to move towards each other. The clamping blocks 22 are fixedly connected to the output end of the second drive device 21. The driving directions of the two sets of second drive devices 21 are opposite and perpendicular to the axis of the bellows 7. The controller is connected to the second drive device 21. When the first sensor 3 senses that the bellows 7 has reached the position where drilling is required, it transmits a signal to the controller. The controller controls the second drive device 21 to drive the two sets of clamping blocks 22 to move towards each other, and the two sets of clamping blocks 22 clamp the bellows 7, thus fixing the bellows 7.

[0039] In this embodiment, two clamping mechanisms 2 are provided, and the drilling mechanism 1 is located between the two clamping mechanisms 2. The second driving device 21 consists of two dual-axis cylinders. The two output shafts of each second driving device 21 are fixedly connected to a clamping block 22. The contact surface between the clamping block 22 and the bellows 7 is an arc surface, which strengthens the limiting effect on the bellows 7.

[0040] The mounting plate 11 is equipped with two or more electric drills 13 and two or more first drive devices 12. The mounting plate 11 is equipped with two or more electric drills 13 and first drive devices 12, which can simultaneously drill multiple holes at the same axial position on the bellows 7.

[0041] The working principle of the adjustable drilling device for the bellows in this embodiment is as follows:

[0042] Move the bellows 7 until the drill bit 132 is aligned with the bottom of the trough of the bellows 7. The first sensor 3 transmits a signal to the controller, which controls the second drive device 21 to drive the clamping block 22 to clamp and position the bellows 7. The L-shaped fixing plate 133 is pushed through the Y connector 121, so that the L-shaped fixing plate 133 slides on the linear guide rail 14 with the slider 15 fixed at its bottom, thereby driving the electric drill 13 to slide on the linear guide rail 14. When the drill bit 132 comes into contact with the bellows 7, the brushless motor 131 drives the drill bit 132 to rotate and drill a hole in the bellows 7.

[0043] Example 3

[0044] This embodiment is the third embodiment of the adjustable drilling device for corrugated pipes of this utility model. This embodiment is similar to embodiment two, except that the mounting frame 6 is provided with two or more drilling mechanisms 1, and each drilling mechanism 1 is arranged along the axial direction of the corrugated pipe 7. By providing two or more drilling mechanisms 1, holes can be drilled simultaneously at different positions along the axial direction of the corrugated pipe 7, thereby improving drilling efficiency.

[0045] like Figure 4 and Figure 5As shown, it also includes an adjustment mechanism 5 for adjusting the horizontal distance between each mounting plate 11. The adjustment mechanism 5 is mounted on the mounting frame 6 and is connected to the drilling mechanism 1. When drilling holes in different corrugated pipes 7, the distance between each hole position along the axis of the corrugated pipe 7 may be different. For example, the different spacing between the corrugations leads to different hole spacing. By using the adjustment mechanism 5 to adjust the horizontal position of the drilling mechanism 1, the distance between each drilling mechanism 1 is changed, and the drilling spacing is adjusted so that when one drilling mechanism 1 reaches the drilling position, the other drilling mechanisms 1 also reach the correct drilling position, increasing the applicability of this equipment to different pipe materials.

[0046] like Figure 4 As shown, the adjustment mechanism 5 includes a lead screw 52, ​​a lead screw support 521, a third drive device 51 for driving the lead screw 52 to rotate, and a guide mechanism 53 for restricting the horizontal movement of the drilling mechanism 1. The lead screw support 521 is fixed on the mounting frame 6, and the lead screw 52 is rotatably connected to the lead screw support 521. The drilling mechanism 1 has a screw hole 111 that mates with the lead screw 52, ​​through which the lead screw 52 passes. The guide mechanism 53 is fixedly mounted on the mounting frame 6 and is connected to the drilling mechanism 1. When the adjustment mechanism 5 is working, the third drive device 51 drives the lead screw 52 to rotate. Because the guide mechanism 53 restricts the direction of movement of the drilling mechanism 1, the drilling mechanism 1 cannot rotate with the lead screw 52. The lead screw 52 drives the drilling mechanism 1 to move horizontally through the screw hole 111, thereby adjusting the position of the drilling mechanism 1.

[0047] In this embodiment, the mounting frame 6 is provided with two drilling mechanisms 1, and screw holes 111 are provided on the mounting plate 11; the third driving device 51 includes a handwheel 511, a main sprocket 512, a driven sprocket 513 and a chain 514. The mounting frame 6 is provided with two seated bearings 515. The main sprocket 512 and the driven sprocket 513 are rotatably connected to the two seated bearings 515 respectively. The handwheel 511 is fixedly connected to the axis of the main sprocket 512. The lead screw 52 is fixedly connected to the axis of the driven sprocket 513. The main sprocket 512 and the driven sprocket 513 are internally connected in the chain 514; the guiding mechanism 53 includes two supports 531 and a guide shaft 532. The supports 531 are fixedly installed on the mounting frame 6. One guide shaft 532 is fixedly installed between the two supports 531 and passes through the two mounting plates 11. The adjustment mechanism 5 is provided with four guiding mechanisms 53. The four guiding mechanisms 53 pass through the four corners of the mounting plate 11 respectively.

[0048] The working principle of the adjustable drilling device for the bellows in this embodiment is as follows: When one drilling mechanism 1 is aligned with the trough of the bellows and the other drilling mechanism 1 is not aligned with the trough, the handwheel 511 is turned. The handwheel 511 drives the main sprocket 512 to rotate. The main sprocket 512 drives the slave sprocket 513 to rotate through the chain 514, which in turn drives the lead screw 52 to rotate. Since the mounting plate 11 can only move horizontally along the guide shaft 532, the drilling mechanism 1 cannot rotate with the lead screw 52. The lead screw 52 drives the mounting plate 11 to move horizontally through the screw hole 111, thereby adjusting the position of the drilling mechanism 1 so that the drilling mechanism 1 is aligned with the trough of the bellows 7.

[0049] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
