Description

Technical Field

[0001] This application relates to the field of pipe fitting processing equipment technology, and in particular to a pipe fitting positioning and drilling device. Background Technology

[0002] In modern industrial manufacturing, especially in the automotive industry, lightweight design has become an important way to improve vehicle performance and reduce energy consumption. Tubes of various shapes and sizes are widely used in automobile bodies, chassis, and other key components to meet requirements for structural strength, weight reduction, and functionality. These tubes often require precise drilling in practical applications to facilitate subsequent assembly and connection work.

[0003] Traditional general-purpose drilling equipment is difficult to provide precise positioning, which requires a lot of time for manual positioning and adjustment before drilling. Furthermore, the positioning accuracy is difficult to guarantee, and drilling position deviations are prone to occur, affecting the accuracy and reliability of subsequent assembly. Utility Model Content

[0004] To improve the processing efficiency of drilling pipe fittings, this application provides a pipe fitting positioning drilling device.

[0005] The pipe fitting positioning and drilling device provided in this application adopts the following technical solution:

[0006] A pipe fitting positioning and drilling device includes a processing table and a bench drill disposed on one side of the processing table. A drilling station is provided on the processing table, located below the drill bit of the bench drill. The drilling station extends through the processing table along its length, and a limiting hole is formed on the top surface of the drilling station. The limiting hole allows the drill bit of the bench drill to penetrate the interior of the drilling station to drill the pipe. A C-shaped pipe support is provided on the processing table, distributed along the length of the processing table with the pipe support and the drilling station. The open end of the pipe supports faces the length of the processing table. The pipe fitting is inserted into the pipe support from the open end, and the end of the pipe to be drilled passes through the drilling station along the length of the processing table. A positioning rod is provided on the processing table, located on the side of the drilling station away from the pipe support. The end of the pipe fitting protrudes from the drilling station and abuts against the positioning rod.

[0007] By adopting the above technical solution, when drilling pipe fittings, workers can first insert the pipe body into the pipe support from the open end, and then slide the pipe fitting along the guide of the pipe support, allowing the end to be drilled to enter the drilling position and exit. When the pipe end contacts the positioning rod, precise positioning is achieved. At this point, the drill bit of the bench drill can accurately align with the predetermined position of the pipe fitting through the limiting hole for drilling. This design not only improves the accuracy and speed of pipe drilling and reduces positional deviations caused by manual positioning, but also enhances overall production efficiency and ensures reliability and accuracy in subsequent assembly processes.

[0008] Optionally, the drilling station has an upward-facing insertion seat on its side wall. One end of the positioning rod is hinged to the side wall of the drilling station. The positioning rod is perpendicular to the length of the processing table. Its hinged end and the insertion seat are located on both sides of the through-outlet of the drilling station along the width of the processing table. The positioning rod is flipped towards the insertion seat, and the free end of the positioning rod is inserted into the insertion seat and engages with it.

[0009] By adopting the above technical solution, the vertical setting and hinged design of the positioning rod enable quick and convenient fixing of the pipe fitting position, reducing positioning errors caused by manual adjustment, and ensuring that the end of the pipe fitting is always in the same position during each drilling, thereby significantly improving drilling accuracy and production efficiency. At the same time, the fit between the positioning rod and the connector effectively prevents pipe fitting displacement or vibration during drilling, further improving drilling quality.

[0010] Optionally, multiple tube supports are distributed along the length of the processing table.

[0011] By adopting the above technical solution, multiple pipe supports can adapt to pipes of different lengths, providing stable support during processing and reducing pipe bending or deformation problems caused by single-point support, thereby improving drilling accuracy and processing quality. At the same time, multi-point support can distribute the stress on the pipe, avoiding localized stress concentration and further enhancing the stability and safety of the pipe.

[0012] Optionally, one positioning rod is provided on each side of the drilling station along the length of the processing table, and multiple pipe supports are provided on each side of the drilling station along the length of the processing table.

[0013] By adopting the above technical solution, a set of positioning rods and pipe supports are set on both sides of the drilling station along the length of the processing table. When both ends of the same pipe need to be drilled, the pipe can be moved horizontally to achieve smooth positioning and drilling. This avoids the pipe from colliding with other equipment in the workshop due to excessive rotation of the pipe, thus improving the safety and convenience of operation.

[0014] Optionally, the machining table has a wedge-shaped groove along its length, the end of the groove extends to the end wall of the machining table, and a plurality of sliders are slidably disposed in the groove. The sliders correspond one-to-one with the tube support and are disposed at the bottom of the tube support. The sliders and the groove slide in a sliding fit.

[0015] By adopting the above technical solution, the design of the slide and slider allows the tube support to be adjusted along the length of the processing table, thereby adapting to the processing needs of tubes of different lengths. Simultaneously, the sliding fit between the slider and the slide ensures the stability and accuracy of the tube support during movement, improving the flexibility and operability of tube positioning, and ultimately enhancing the overall efficiency and precision of drilling operations.

[0016] Optionally, the processing table is provided with a fixing seat for clamping the end of the pipe. There is one fixing seat at each end of the processing table, and the bottom of each fixing seat is provided with a guide block that slides with a sliding groove. Several clamping plates are slidably arranged on the side wall of the fixing seat facing the pipe body support. The clamping plates are distributed around the circumference of the fixing seat. A guide groove is opened on the side wall of the fixing seat facing the pipe body support for each clamping plate. The extension lines of the several guide grooves intersect at the center of the fixing seat. The fixing seat is provided with a driving component that drives the several clamping plates to slide synchronously toward the center of the fixing seat.

[0017] By adopting the above technical solution, after the pipe body is inserted into the pipe support from the open end, the fixed seat is pushed, causing it to slide towards the end of the pipe until the end of the pipe enters the space between several clamping plates. A driving component then moves multiple clamping plates simultaneously towards the center of the fixed seat, ensuring the end of the pipe is securely clamped. The fixed seat is continued to be pushed, causing the entire pipe to slide smoothly along the pipe support into the drilling position until the end of the pipe touches the positioning rod and stops. This design effectively reduces the risk of pipe deflection during drilling, significantly improving the accuracy and efficiency of drilling operations.

[0018] Optionally, the fixing base includes a fixing cover and a turntable. The fixing cover is located on the side facing the tube support, and the turntable is coaxially rotatable on the side of the fixing cover away from the tube support via a bearing. The driving component includes a limit strip and a handle arranged in a spiral shape. The limit strip is arranged around the center of the turntable on the side wall of the turntable facing the inside of the fixing cover, and the handle is arranged on the side wall of the turntable away from the fixing cover. The end of each clamping plate located inside the fixing cover is inserted into the limit strip in a horizontal direction.

[0019] By adopting the above technical solution, the fixing seat can quickly fix and release the end of the pipe, improving the ease of operation during the pipe drilling process. Simultaneously, the rotation of the turntable drives the clamping plate to move synchronously, improving the effective clamping of pipes of different diameters and further enhancing the stability and accuracy of the drilling operation.

[0020] Optionally, a ratchet ring is fitted on the outer side wall of the fixed cover extending from the turntable, and a pawl that engages with the ratchet ring is rotatably provided on the top side wall of the fixed cover. In its natural state, the pawl allows the turntable to rotate in the direction of clamping the end of the pipe.

[0021] By adopting the above technical solution, the ratchet ring fitted on the outer sidewall of the turntable and the pawl rotatably mounted on the top sidewall of the fixing cover cooperate with each other, allowing the turntable to rotate only in the direction of clamping the end of the pipe under natural conditions. This design effectively prevents the pipe from loosening due to accidental reverse rotation during operation, improves clamping stability, and ensures the safety and reliability of the drilling process. At the same time, the one-way locking mechanism simplifies the operation process and improves work efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When drilling pipe fittings, the operator first inserts the pipe body into the pipe support from the open end, then slides the pipe along the guide of the support until the end to be drilled enters and exits the drilling position. Precise positioning is achieved when the pipe end contacts the positioning rod. At this point, the drill bit of the bench drill can accurately align with the predetermined position of the pipe fitting through the limiting hole for drilling. This design not only improves the accuracy and speed of pipe drilling and reduces positional deviations caused by manual positioning, but also enhances overall production efficiency and ensures reliability and accuracy in subsequent assembly processes.

[0024] 2. The vertical setting and hinged design of the positioning rod enables quick and convenient fixing of the pipe fitting position, reducing positioning errors caused by manual adjustment, and ensuring that the end of the pipe fitting is always in the same position during each drilling, thereby significantly improving drilling accuracy and production efficiency. At the same time, the fit between the positioning rod and the insertion seat effectively prevents pipe fitting displacement or vibration during drilling, further improving drilling quality.

[0025] 3. Multiple pipe supports can accommodate pipes of different lengths, providing stable support during processing and reducing bending or deformation problems caused by single-point support, thereby improving drilling accuracy and processing quality. Simultaneously, multi-point support can distribute the stress on the pipe, avoiding localized stress concentration and further enhancing the stability and safety of the pipe.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a pipe positioning drilling device.

[0034] Example 1

[0035] Reference Figure 1 A pipe positioning drilling device includes a processing table 1, with a bench drill 2 mounted on one side of the processing table 1, and the processing table 1 fixedly mounted on the processing surface of the bench drill 2. A drilling station 3 is fixedly mounted on the processing table 1 below the drill bit of the bench drill 2, and is arranged through the length of the processing table 1. A limiting hole 31 is opened on the top surface of the drilling station 3, and the diameter of the limiting hole 31 is slightly larger than the diameter of the drill bit. Several C-shaped pipe supports 4 are distributed on the processing table 1 along its own length, and the open ends of the pipe supports 4 all face the same side of the length of the processing table 1. A positioning rod 5 is hinged to the processing table 1, and one positioning rod 5 is arranged on each side of the drilling station 3 along the length of the processing table 1.

[0036] Reference Figure 1In actual operation, the worker first inserts the pipe fitting into the open end of the pipe support 4 until the end to be drilled passes through the drilling station 3 and contacts the positioning rod 5. At this point, the positioning rod 5 on one side can be flipped to make it fit tightly against the corresponding pipe end. Then, the bench drill 2 is started, and the drill bit enters the drilling station 3 along the limiting hole 31 to perform precise drilling on the pipe fitting.

[0037] Reference Figure 1 In this embodiment, the bench drill 2 is a commercially available portable drilling device, while the processing table 1 is a rectangular work platform made of high-strength steel. The drilling station 3 is a metal frame on the processing table 1 specifically used to restrict the end of the pipe to be drilled. In this embodiment, two pipe supports 4 are fixedly installed on both sides of the drilling station 3. One pipe support 4 is also fixedly installed inside the drilling station 3. The limiting hole 31 on the top surface of the drilling station 3 extends vertically through to the interior of the pipe support 4.

[0038] Reference Figure 1 An upward-facing insertion seat 6 is fixedly installed on the side wall of the drilling station 3. The positioning rod 5 is set perpendicular to the length direction of the processing table 1, and one end of the positioning rod 5 is hinged to the side wall of the drilling station 3. The hinged end of the positioning rod 5 and the insertion seat 6 are located on both sides of the through outlet of the drilling station 3 along the width direction of the processing table 1. The positioning rod 5 is flipped towards the insertion seat 6, and the free end of the positioning rod 5 is inserted into the insertion seat 6 and engaged with the insertion seat 6.

[0039] The implementation principle of the pipe positioning drilling device in this application embodiment is as follows: In actual operation, the operator first flips the positioning rod 5 at the outlet of the drilling station 3 so that it is inserted into the insertion seat 6. Then, the pipe is inserted from the open end of the pipe body support 4 until the end of the pipe to be drilled passes through the pipe body support 4 in the drilling station 3 and is tightly fitted with the positioning rod 5. Then, the bench drill 2 is started, and the drill bit enters the drilling station 3 along the limiting hole 31 to perform precise drilling on the pipe.

[0040] Example 2

[0041] Reference Figure 2 The difference between this embodiment and embodiment 1 is that the processing table 1 is provided with a fixing seat 7 for clamping the end of the pipe.

[0042] Reference Figure 2 The processing table 1 has a wedge-shaped groove 11 along its length. The end of the groove 11 extends to the end wall of the processing table 1. Several sliders 41 are slidably arranged in the groove 11. The sliders 41 correspond one-to-one with the pipe support 4 outside the drilling station 3 and are fixedly arranged at the bottom of the pipe support 4. The sliders 41 and the groove 11 slide together.

[0043] Reference Figure 2 and Figure 3 One fixing base 7 is provided at each end of the processing table 1. The fixing base 7 includes a fixing cover 71 and a turntable 72. The fixing cover 71 is located on the side facing the tube support 4. A guide block 711 that slides with the slide groove 11 is fixedly provided at the bottom of the fixing cover 71. Several guide grooves 712 are distributed circumferentially on the side wall of the fixing cover 71 facing the tube support 4. In this embodiment, four guide grooves are used as an example. The extension lines of the four guide grooves 712 intersect at the center of the fixing cover 71. A clamping plate 8 is slidably provided in each guide groove 712. The clamping plates 8 are arc-shaped. The arc centers of the four clamping plates 8 are all located on the side close to the center of the fixing cover 71. A rubber pad 81 is fixedly provided on the inner arc side wall of the clamping plate 8.

[0044] Reference Figure 2 , Figure 3 and Figure 4 The turntable 72 is coaxially rotatably connected to the side of the fixed cover 71 away from the pipe support 4 via a bearing (not shown in the figure). The fixed base 7 is equipped with a driving component 9 that drives several clamping plates 8 to slide synchronously towards the center. In this embodiment, the driving component 9 includes a limiting strip 91 and a handle 92. The limiting strip 91 is spirally fixed on the side wall of the turntable 72 facing the inside of the fixed cover 71 and is coiled around the center of the turntable 72. The handle 92 is fixed on the side wall of the turntable 72 away from the fixed cover 71. One end of each clamping plate 8 inside the fixed cover 71 is horizontally inserted into the limiting strip 91. When the operator rotates the handle 92, the turntable 72 drives the limiting strip 91 to rotate, causing the clamping plates 8 to move towards the center along the guide groove 712, ultimately clamping the end of the pipe tightly.

[0045] Reference Figure 2 , Figure 3 and Figure 4 In order to improve the locking effect of the clamping plate 8 after clamping the pipe, a ratchet ring 721 is fixedly sleeved on the outer ring side wall of the rotating plate 72 extending out of the fixing cover 71, and a pawl 713 that is inserted and engaged with the ratchet ring 721 is rotatably provided on the top side wall of the fixing cover 71.

[0046] Reference Figure 2 , Figure 3 and Figure 4In this embodiment, the ratchet ring 721 is formed by a circular metal strip with teeth arranged in a serrated pattern, with grooves formed between adjacent teeth. The pawl 713 is a small metal hook, one end of which is rotatably mounted on the top side wall of the fixing cover 71, and the other end extends into the teeth of the ratchet ring 721. When the turntable 72 rotates clockwise (i.e., in the clamping direction), the pawl 713 engages in the groove of the ratchet ring 721, preventing reverse rotation and ensuring that the clamping plate 8 remains taut. Conversely, when it is necessary to release the clamping plate 8, simply move the pawl 713 gently to disengage it from the teeth of the ratchet ring 721, and the turntable 72 can then rotate freely counterclockwise to return to its initial position.

[0047] The implementation principle of Example 2 is as follows: In actual operation, the operator first inserts one end of the pipe fitting between the clamping plates 8 in the fixed seat 7, and then manually rotates the handle 92, causing the turntable 72 to rotate, thereby pushing the clamping plates 8 towards the center of the fixed cover 71 until the pipe fitting is clamped. During this process, the pawl 713 will engage in the groove of the ratchet ring 721, preventing reverse rotation, thus ensuring that the clamping plates 8 remain taut at all times. Conversely, when it is necessary to loosen the clamping plates 8, simply gently move the pawl 713 to disengage it from the teeth of the ratchet ring 721, and the turntable 72 can rotate freely counterclockwise to return to its initial position. This improves the safety and convenience of the operation and greatly reduces the possibility of misoperation.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
