Description

Technical Field

[0001] This application relates to the field of pipe fitting processing technology, and in particular to a drilling and riveting integrated device for tubular components. Background Technology

[0002] In electrical equipment, tubular components are widely used. A tubular component includes a tube and fittings riveted to it to ensure a stable connection between the tubular component and the corresponding parts. Especially in the structure system of the contact network of the traction power supply system, a large number of contact network cantilever arms and positioning tubes are used. The contact network cantilever arm is usually composed of a cantilever tube and connecting lugs riveted to the cantilever tube. It mainly supports and positions the power lines of electrified railways, urban rail transit and trams. It is installed on the positioning tube to transfer the gravity, tension and wind load of the power lines to the positioning tube and the foundation.

[0003] With the development of technology, the requirements for the processing precision of tubular components have also increased. Currently, the processing of tubular components requires operators to drill holes in the tubular components using a radial drilling machine. Then, the drilled tubular components are moved to a hydraulic press for riveting. This process is inefficient and labor-intensive. Furthermore, during the process of moving the tubular components from the radial drilling machine to the hydraulic press, misalignment of the drilled holes on the pipes and fittings is likely to occur. Alternatively, due to inaccurate manual visual inspection, the drilled holes on the pipes and / or fittings may deviate from the riveting direction of the hydraulic press, resulting in unstable riveting between the fittings and pipes and unsightly rivet shapes after riveting. Therefore, the processing precision of tubular components is greatly affected by human factors. Summary of the Invention

[0006] The tubular component drilling and riveting integrated equipment provided in this application integrates drilling and riveting functions, and correspondingly sets a first fixing component and a second fixing component to fix the tubular components and fittings respectively. During the processing of the tubular components, there is no need to move the tubular components to other equipment, so that the drilling direction of the tubular components and fittings is parallel to the riveting direction, ensuring a stable connection between the tubular components and fittings.

[0029] The following is a detailed description of this application.

[0030] like Figures 1 to 6As shown, in order to solve the above-mentioned technical problems, the embodiments of this application provide a drilling and riveting integrated device for a tubular component 5, including: a working body 1; a drilling and riveting mechanism 2, which is disposed on the working body 1 and is used to perform drilling and riveting work in a preset working area; and a fixing mechanism 3, including a first fixing component 31 and a second fixing component 32 disposed on the working body 1. The first fixing component 31 is assembled with the pipe fitting 51 of the tubular component 5, and the second fixing component 32 is assembled with the accessory 52 of the tubular component 5. The first fixing component 31 and the second fixing component 32 cooperate to set the overlapping part between the pipe fitting 51 and the accessory 52 within the working area of ​​the drilling and riveting mechanism 2.

[0031] The drilling and riveting mechanism 2 includes a drilling assembly 21 for drilling holes and a riveting assembly 22 for riveting. The drill bit of the drilling assembly 21 rotates at high speed around its own axis under the drive of the corresponding drilling driver 211 to drill holes in the overlapping part between the pipe 51 and the fitting 52. The riveting assembly 22 includes a first riveting part 221 and a second riveting part 222, which are respectively disposed on both sides of the tubular component 5 along the corresponding drilling direction. The first riveting part 221 and the second riveting part 222 can move towards each other to squeeze the rivet in the drill hole, thereby completing the riveting work.

[0032] The working area refers to the spatial area in which the drilling assembly 21 and the riveting assembly 22 can perform corresponding drilling and riveting operations. The size of this area is determined by the range of motion of the drilling and riveting mechanism 2 and the drilling size of the drill bit component 212 of the drilling assembly 21.

[0033] By setting up an integrated drilling and riveting device that combines drilling and riveting functions, and by setting up a first fixing component 31 and a second fixing component 32 to fix the pipe fitting 51 and the accessory 52 respectively, the pipe fitting 5 does not need to be moved to other equipment during the processing of the pipe fitting 5. This ensures that the drilling direction of the pipe fitting 51 and the accessory 52 is parallel to the riveting direction, thus ensuring a stable connection between the pipe fitting 51 and the accessory 52. ​​This effectively improves the processing accuracy of the pipe fitting 5, increases processing efficiency, reduces the number of operators required for the processing, and lowers labor costs.

[0034] In one embodiment of this application, the middle portion between the two ends of the pipe fitting 51 is assembled with the fitting 52, and the second fixing component 32 extends to a radial side of the pipe fitting 51 and is detachably assembled with the fitting 52; preferably, the fitting 52 is sleeved on the peripheral wall of the pipe fitting 51; another preferred embodiment is that the fitting 52 has a contact portion located on a radial side of the pipe fitting 51, and the contact portion is fitted against the peripheral wall of the pipe fitting 51.

[0035] In another embodiment of this application, the end of the pipe 51 along the first direction is assembled with the fitting 52. The second fixing component 32 includes a support structure 321 connected to the working body 1; an extension structure 322 connected to the support structure 321 and extending from the support structure 321 to the first direction side of the first fixing component 31; and an assembly structure 323 connected to the extension structure 322. The assembly structure 323 is detachably assembled with the fitting 52.

[0036] With the above configuration, for the tubular assembly 5 with accessory 52 located on the end of pipe fitting 51, an extension structure 322 extending to the vicinity of the end of pipe fitting 51 is specifically configured, and the support structure 321 enables accessory 52 to be accurately and stably positioned on the first direction side of the first fixing component 31, thereby forming a reliable assembly with the end of pipe fitting 51, reducing the shaking of accessory 52 during drilling and riveting, and improving the assembly accuracy of tubular assembly 5.

[0037] In the embodiments of this application, the fitting 52 has an insert portion extending into the interior of the pipe 51, the insert portion overlapping the peripheral wall at the first direction end of the pipe 51, and the drilling and riveting mechanism 2 performs drilling and riveting operations on the overlapping portion of the insert portion and the pipe 51; or, the fitting 52 has a sleeve portion sleeved on the peripheral wall at the first direction end of the pipe 51, and the drilling and riveting mechanism 2 performs drilling and riveting operations on the overlapping portion of the sleeve portion and the pipe 51.

[0038] In the embodiments of this application, the extension structure 322 is a rod-shaped structure fixedly connected to the support structure 321, so that the extension structure 322 stably supports the assembly structure 323 and the accessory 52 mounted on the assembly structure 323.

[0039] In the embodiments of this application, the extension structure 322 includes at least two extensions, and at least some of the extensions are movably connected to each other.

[0040] Through the above-mentioned configuration, the extension structure 322 can extend, swing, or deflect within a certain range through the relative movement between the extension parts. This allows the second fixing component 32 to adjust the position of the accessory 52 according to the actual position of the pipe 51 and the size of the accessory 52, thereby adaptively adjusting the drilling and riveting angles. This enhances the adaptability of the drilling and riveting integrated equipment to tubular components 5 of different specifications and assembly methods, improving the equipment's versatility.

[0041] Furthermore, when drilling and riveting are required at multiple locations of the tubular component 5, one of the riveting locations can be positioned in the working area first, and drilling and riveting can be performed to complete the initial riveting of the fitting 52 and the pipe 51. Then, through the relative movement between the extensions, other riveting locations can be positioned in the working area in sequence, so that the drilling and riveting mechanism 2 can perform drilling and riveting at other locations without having to disassemble and assemble the fitting 52 from the second fixed component, making it more convenient to use.

[0042] In an alternative embodiment of this application, the extensions are rotatably connected; by adjusting the relative rotation between the extensions, the connection position between the extension structure 322 and the assembly structure 323 is adjusted, thereby adaptively supporting the fitting 52 on the pipe 51; preferably, the extension structure 322 includes at least three extensions connected end to end, the extensions are rotatably connected, and the rotation axes at at least two rotatable connections have an included angle; more preferably, the rotation axes at at least two rotatable connections are perpendicular to each other; so that the extension structure 322 can make three-dimensional adjustments to the position of the assembly structure 323, thereby improving the flexibility of adjustment and further improving the versatility of the drilling and riveting integrated equipment.

[0043] However, the rotating connection between the extensions is prone to deformation due to stress concentration, and the adjustment accuracy of the extensions is highly susceptible to human factors when adjusting them, which can easily lead to positional deviation. Therefore, a preferred embodiment of this application is proposed, wherein the extension structure 322 includes a first extension 3221 connected to the support structure 321. The first extension 3221 is a sleeve-shaped extension with its axis extending along a first direction. The opening of the sleeve-shaped first extension 3221 faces the first fixing component 31. The tube 51 is coaxially disposed in the first extension 3221 with the opening facing upward through the first fixing component. A second extension 3222 is movably inserted into the first extension 3221, and one end of the second extension 3222 facing the first fixing component 31 is connected to the assembly structure 323.

[0044] With the above configuration, by allowing the second extension 3222 to be movably inserted into the sleeve-shaped first extension 3221 to form a telescopic rod-shaped extension structure 322, the position of the accessory 52 can be adjusted; and the first extension 3221 is coaxially arranged with the pipe 51, so that the assembly structure 323 can be continuously and accurately adjusted in the axial direction of the pipe 51, ensuring that the accessory 52 can be accurately pushed to the optimal position for docking with the end of the pipe 51, which significantly improves the positioning accuracy of the overlapping area.

[0045] In the embodiments of this application, the second extension 3222 is a straight rod-shaped structure; preferably, the second extension 3222 is coaxially arranged with the first extension 3221; the inner wall of the first extension 3221 is shaped to match the second extension 3222.

[0046] In one embodiment of this application, the cross-section of the second extension 3222 is an ellipse or a regular polygon. By matching the shape of the peripheral wall of the second extension 3222 with the inner wall of the first extension 3221, the second extension 3222 is prevented from causing the accessory 52 to rotate around its own axis during drilling and riveting operations. When it is necessary to adjust the drilling angle, the second extension 3222 can be pulled out from the first extension 3221, rotated to the corresponding angle, and then reinserted into the first extension 3221.

[0047] However, the polygonal cross-section of the second extension 3222 makes angle adjustment cumbersome. Furthermore, during adjustment, the second extension 3222 must remain connected to the tubular component 5. When the second extension 3222 separates from the first extension 3221, the first extension 3221 suddenly loses the support of the second extension 3222, easily causing some degree of wobbling. At this point, fixing the accessory 52 and the pipe 51 with only one rivet can easily lead to misalignment during wobbling, resulting in reduced assembly accuracy between the accessory 52 and the pipe 51. Therefore, in the preferred embodiment of this application, the second extension 3222 has a circular cross-section, allowing it to rotate freely within the first extension 3221, thereby facilitating adjustments during drilling and... When riveting, it is only necessary to reduce the assembly strength between the first fixing part and the tube 51, and then rotate the second extension 3222 to make the tubular component 5 rotate around the axis, so as to complete the operation of adjusting the drilling position and drilling angle. There is no need to remove the second extension 3222 from the first extension 3221, which is convenient to use and improves the processing accuracy. In addition, although the first extension 3221 cannot limit the circumferential position of the rod-shaped second extension 3222 through shape matching, the assembly strength between the first fixing part and the tube 51 is sufficient to stably support the tube 51 and the accessory 52, thereby limiting the position of the second extension 3222. The accessory 52 will not cause the second extension 3222 to rotate during drilling and riveting.

[0048] In the embodiments of this application, a track is provided on the first extension 3221 or the second extension 3222, and a slider is correspondingly provided on the second extension 3222 or the first extension 3221. The slider is movably mounted on the track. Specifically, there are two riveting positions on the tubular component 5 that require drilling and riveting. When the slider moves to one end of the track, the first riveting position of the tubular component 5 is located within the working area. When the slider moves to the other end of the track, the second riveting position of the tubular component 5 is located within the working area.

[0049] Through the above settings, the cooperation of the track and slider provides a clear guiding path for the movement of the extension, effectively limiting the swaying and offset of the second extension 3222 in the radial direction, and significantly improving the positional accuracy of the extension structure 322 during the extension and retraction process, thereby ensuring the accuracy of the drilling and riveting work of the drilling and riveting equipment on the tubular component 5.

[0050] In the embodiments of this application, a concave elongated track groove is provided on the inner wall of the first extension 3221 or the peripheral wall of the second extension 3222 to form a track. Correspondingly, the slider is a sliding protrusion protruding from the peripheral wall of the second extension 3222 or the inner wall of the first extension 3221. The protruding end of the sliding protrusion extends into the track groove and slidably contacts the groove wall in the width direction of the track groove. Specifically, the track groove is provided on the inner wall of the first extension 3221, and the slider is provided on the peripheral wall of the second extension 3222.

[0051] In one embodiment of this application, the track is composed of multiple track segments connected end to end, and there is an angle between adjacent track segments; preferably, the angle between adjacent track segments is 90 degrees; more preferably, at least one track segment extends in a direction parallel to the axial direction of the first extension 3221, and the adjacent track segment extends around the axis of the first extension 3221; so that the first extension 3221 can be advanced along the first direction along the axial direction through the track segment, and move to the starting point of another track segment, and then rotate along another track segment, thereby realizing the adjustment of the drilling and riveting positions.

[0052] In another preferred embodiment of this application, the track is spiral and is coaxially arranged with the axis of the first extension 3221; preferably, the rotation angle of the spiral track is 90 degrees.

[0053] With the above settings, when the operator is operating the equipment, the spiral track enables the propulsion and rotation of the accessory 52 to be completed in one action, without the need for separate axial pushing and rotation operations, which significantly reduces labor intensity and improves assembly efficiency.

[0054] Furthermore, when the drilling and riveting integrated equipment can automatically adjust the second extension 3222, the helical track can achieve compound motion through a single drive source, simplifying the control logic and improving the equipment response speed. In one embodiment, the drive source of the drilling and riveting integrated equipment is connected to a push rod, which can drive the push rod to move axially. The drive end of the push rod extends into the interior of the first extension 3221 and is rotatably connected to the corresponding end of the second extension 3222. The push rod drives the second extension 3222 to move axially, and the second extension 3222 rotates accordingly through the cooperation of the track and the slider. Specifically, the peripheral wall of the first extension 3221 near the push rod end is provided with an inwardly concave annular groove, and the end of the push rod is provided with a pawl extending into the annular groove, so that the push rod and the second extension 3222 can be rotatably connected relative to each other.

[0055] In the embodiments of this application, during the riveting of the first rivet, the extension structure 322 retracts to its minimum size; preferably, when the extension structure 322 retracts to its minimum size, the slider on the second extension 3222 contacts the end wall of the first direction end of the spiral track on the first extension 3221; another preferred embodiment is that when the extension assembly 322 retracts to its minimum size, the end wall of the first direction reverse end of the spiral track on the second extension 3222 contacts the slider on the inner wall of the first extension 3221; since before riveting the first rivet, the fitting 52 and the tube 51 The stability is poor because the second extension 3222 is limited only by friction. By keeping the extension structure 322 in a contracted state, and after the first fixing component 21 is assembled with the tube 51, the first fixing component 21 can limit the second extension 3222 along the first direction with the tube 51 and the accessory 52. ​​Furthermore, through the limiting cooperation between the slider and the spiral track, the second extension 3222 can provide stable support for the accessory 52, preventing the accessory 52 and the tube 51 from rotating relative to each other during drilling and riveting operations, thereby improving the processing accuracy of the drilling and riveting equipment for the tubular component 5.

[0056] In the embodiments of this application, a locking component is provided on the first extension 3221, and the locking component is detachably connected to the second extension 3222. By adding the locking component, the second extension 3222 is prevented from rotating accidentally during drilling and riveting operations, thereby improving the processing accuracy of the drilling and riveting integrated equipment for the tubular component 5.

[0057] In the embodiments of this application, one end of the locking component is rotatably connected to the outer wall of the first extension 3221, and the other end extends to the vicinity of the second extension 3222. The locking component is provided with a hook portion, and the second extension 3222 is provided with a corresponding slot. The hook portion engages with the slot. Preferably, the second extension 3222 is provided with multiple slots, and the hook portion can selectively engage with the corresponding slot. Alternatively, one end of the locking component is rotatably connected to the outer wall of the first extension 3221, and the other end is connected to the side wall of the second extension 3222. The separable contact locking component and the contact portion of the second extension 3222 are connected by bolts. Preferably, the second extension has multiple bolt holes, and the locking component can be selectively connected to the corresponding bolt holes by bolts. Under normal conditions, the locking component can be located at a position far away from the second extension 3222. When drilling and riveting are performed, the locking component can be rotated to approach the second extension 3222 and engage with the second extension 3222 to lock the second extension. The structure is simple, reliable, and easy to use.

[0058] In one embodiment of this application, the assembly structure 323 is clamped onto the accessory 52, or the assembly structure 323 is snapped into the accessory 52.

[0059] In another preferred embodiment of this application, the accessory 52 is provided with a connecting hole, and the opening orientation of the connecting hole has an angle with the first direction; the assembly structure 323 includes a first assembly part 3231 connected to the extension structure 322, the first assembly part 3231 extends to the opening orientation side of the connecting hole, and a second assembly part 3232 is connected to the extension end of the first assembly part 3231, and the second assembly part 3232 is inserted into the connecting hole.

[0060] It should be noted that the connecting hole can be an opening specifically for connecting with the first assembly part 3231; or it can be an opening originally present on the accessory 52. ​​The assembled tubular component 5 is connected to other components through the connecting hole.

[0061] With the above configuration, since the opening of the connecting hole has an angle with the axis of the pipe 51 extending along the first direction, the second assembly part 3232 is inserted into the connecting hole and can form effective support in a plane perpendicular to the first direction, preventing the accessory 52 from slipping during drilling or riveting, and significantly improving the reliability of the second fixing component 32 in fixing the accessory 52.

[0062] In the embodiments of this application, the extended end of the second assembly part 3232 is inserted into the connecting hole. A limiting part that expands perpendicular to the extension direction is provided on the middle part of the second assembly part 3232. The side wall of the limiting part that is closer to the extended end can contact the accessory 52. ​​Preferably, the limiting part is a columnar structure. The axis of the limiting part is parallel to the extension direction of the second assembly part 3232. The diameter of the second assembly part 3232 is larger than the diameter of the connecting hole. By providing the limiting part, the accessory 52 is limited and the accessory 52 is accurately positioned.

[0063] In the embodiments of this application, the diameter of the extension end of the second assembly part 3232 is equal to the diameter of the connecting hole.

[0064] In the embodiments of this application, the second assembly part 3232 is detachably connected to the first assembly part 3231; the second assembly part 3232 can be replaced and adapted for accessories 52 of different specifications, thereby improving the versatility of the second fixing component 32.

[0065] In the embodiments of this application, the first assembly part 3231 includes a first connecting rod connected to the extension structure 322 and a second connecting rod disposed on the first connecting rod. The second connecting rod is connected to the second assembly part 3232, and there is an included angle between the first connecting rod and the second connecting rod. Specifically, the first connecting rod is perpendicular to the axis of the pipe 51, and the second connecting rod is parallel to the axis of the pipe 51.

[0066] In the embodiments of this application, the working body 1 includes a main box 11 extending upward from the ground; a workbench 12 disposed on the opposite side of the main box 11 in the first direction; a working support 13 located above the main body and connected to the main box 11; and a first fixing component 31 and a second fixing component 32 cooperating to mount the tubular component 5 between the working support 13 and the workbench 12.

[0067] In the embodiments of this application, the support structure 321 of the second fixing component 32 is located between the working bracket 13 and the worktable 12, and is connected to the side wall of the main housing 11 on the first direction opposite side; preferably, the support structure 321 extends downward along the side wall of the main housing 11 to the top of the worktable 12, and bends along the worktable 12, and the bent extension of the support structure 321 is connected to the worktable 12; by setting the L-shaped support structure 321, the stability of the connection between the support structure 321 and the working body 1 is improved.

[0068] In the embodiments of this application, the first fixing component 31 includes at least two relatively movable clamping parts, which are engaged and clamped on the peripheral wall of the pipe 51.

[0069] With the above-mentioned configuration, the clamping part is designed to be relatively movable, and its spacing can be adjusted according to the outer diameter of the pipe 51, thereby adapting to various specifications of tubular components 5, significantly improving the versatility and application range of the drilling and riveting integrated equipment; and the clamping part can apply clamping force to the pipe 51 from different circumferential positions, so that the pipe 51 is uniformly constrained in the radial direction, effectively preventing the pipe 51 from shaking or shifting during processing, and improving the positioning accuracy and assembly stability of the pipe 51.

[0070] In one embodiment of this application, the first fixing component 31 includes a first bracket and two third clamping parts arranged along a second direction, wherein the second direction is orthogonal to the first direction, and the two third clamping parts are movably connected to the first clamping bracket; preferably, both the first and second directions are horizontal, and both third clamping parts are disposed on the top of the first bracket; another preferred embodiment is that the working body 1 includes a worktable 12, and the clamping parts are disposed on the worktable 12.

[0071] In another embodiment of this application, the first fixing component 31 includes an annular second bracket and at least two fourth clamping portions arranged circumferentially along the inner ring side of the second bracket, each of the fourth clamping portions being movably connected to the second bracket towards the center.

[0072] In another embodiment of this application, the working body 1 includes a workbench 12, and the first fixing component 31 includes a first clamping part 311 disposed on the table surface of the workbench 12, and a first support groove 3111 disposed on the top wall of the first clamping part 311; a second clamping part 312 disposed above the first clamping part 311, and connected to the workbench 12 or the first clamping part 311 at an adjustable distance, and a second support groove 3121 disposed on the bottom wall of the second clamping part 312, which is directly opposite to the first support groove 3111, and the second support groove 3121 cooperates with the first support groove 3111 to clamp the pipe 51.

[0073] With the above configuration, by setting the worktable 12 in the first clamping part 311, the first support groove 3111 of the first clamping part 311 can provide stable support for the pipe 51. During the process of clamping or releasing the pipe 51 by the first fixing component 31, the first clamping part 311 always remains stationary. Therefore, when adjusting the drilling and riveting position of the tubular component 5, the first clamping part 311 can ensure that the axis of the tubular component 5 does not deviate perpendicular to the axis direction, thereby improving the riveting accuracy.

[0074] In the embodiments of this application, the first fixing component 31 includes an adjusting rod 313, which is disposed on the table surface of the workbench 12 and extends upward. The second clamping part 312 is provided with an adjusting hole that is movably sleeved on the adjusting rod 313, and the upper end of the adjusting rod 313 protrudes from the second clamping part 312. An adjusting nut 314 is threadedly connected to the upper end of the adjusting rod 313, and the bottom end face of the adjusting nut 314 abuts against the second clamping part 312. The second clamping part 312 is moved downward along the adjusting rod 313 by the adjusting nut 314, so that the second clamping part 312 contacts the pipe 51. By appropriately turning the adjusting nut 314, the clamping force between the first fixing component 31 and the pipe 51 can be adjusted. The operation is simple and convenient.

[0075] In the embodiments of this application, there are two adjusting rods 313, which are symmetrically arranged on both sides of the first clamping part 311. The two sides of the second clamping part 312 are respectively sleeved on the corresponding adjusting rods 313 through corresponding adjusting holes. The upper end of each adjusting rod 313 is threaded with an adjusting nut 314. Specifically, the adjusting rods 313 are arranged on both sides of the first clamping part 311 along the second direction, and the second direction, the first direction, and the vertical direction are orthogonal to each other.

[0076] In one embodiment of this application, the first support groove 3111 and the second support groove 3121 are both arc-shaped grooves that fit and contact the periphery of the pipe 51, and the radius of the arc-shaped groove is equal to or slightly smaller than the diameter of the pipe 51.

[0077] In another preferred embodiment of this application, at least one clamping wall 31211 is provided on the second support groove 3121 and / or the first support groove 3111. The clamping wall 31211 is a straight wall or an arc-shaped wall with a radius of curvature greater than the radius of the pipe 51. The clamping wall 31211 abuts against the pipe 51.

[0078] With the above configuration, a stable point support is formed when the clamping wall 31211 contacts the outer wall of the pipe 51. Compared with the arc-shaped groove that fits the pipe 51, the contact area is smaller, which increases the pressure between the two and thus increases the maximum static friction between the first clamping part 311 and the pipe 51. This prevents the pipe 51 from accidentally rotating around its own axis during drilling or riveting. At the same time, since the radius of curvature of the clamping wall 31211 is greater than the radius of the pipe 51, the same support groove structure can adapt to pipes 51 with different outer diameters within a certain range. When the diameter of the pipe 51 changes, the clamping wall 31211 can still maintain effective contact and provide stable support, thereby improving the versatility of the first fixing component 31 and reducing the frequency of clamp replacement.

[0079] In the embodiments of this application, the first support groove 3111 is an arc-shaped groove with an upward opening, and at least part of the groove wall of the second support groove 3121 is configured as a clamping wall 31211; preferably, the number of clamping walls 31211 is 2, symmetrically arranged on both sides of the vertical line in the second support groove 3121; in one embodiment, the two clamping walls 31211 are connected; in another embodiment, the second support groove 3121 is provided with a spacer top wall 31212 between the two clamping walls 31211, and the spacer top wall 31212 is connected to the corresponding clamping wall. The holding walls 31211 are smoothly connected, and the radius of curvature of the spacer top wall 31212 is smaller than the radius of curvature of the clamping wall 31211. Preferably, the radius of curvature of the spacer top wall 31212 is smaller than the radius of the pipe 51, so that when the second support groove 3121 clamps pipes 51 of different specifications, its spacer top wall 31212 is spaced apart from the pipe 51, thereby avoiding the spacer top wall 31212 from contacting the peripheral wall of the pipe 51, which would reduce the maximum static friction force between the first fixing component 31 and the pipe 51.

[0080] In the embodiments of this application, the drilling and riveting mechanism 2 includes a drilling assembly 21 and a riveting assembly 22. The drilling assembly 21 includes a drilling driver 211 and a drill bit component 212 that is pulverizedly connected to the drilling driver 211. The drilling driver 211 drives the drill bit component 212 to perform drilling work on the tubular assembly 5. The riveting assembly 22 includes a first riveting part 221 and a second riveting part 222, which are symmetrically arranged on both sides of the axis of the tubular assembly 5. The first riveting part 221 and the second riveting part 222 can move towards each other and squeeze the rivet in the drill hole to perform riveting work.

[0081] In the embodiments of this application, the first fixing component 31 supports the end of the pipe 51 to be drilled and riveted, which is erected between the working belt and the working bracket 13 along the first direction; the drilling component 21 and the first riveting part 221 are connected to the working bracket 13, and the second riveting part 222 is disposed on the worktable 12.

[0082] In the embodiments of this application, under normal conditions, the top of the second riveting part 222 is lower than the bottom of the second support groove 3121; when performing the riveting operation, the top of the second riveting part 222 and the bottom of the second support groove 3121 are at the same vertical height.

[0083] In the embodiments of this application, the drilling and riveting integrated device includes a drive mechanism 4, including a drive component 41 and a transmission component 42 that is drively connected to the drive component 41. The drilling component 21 and the first riveting part 221 are mounted on the transmission component 42, and the moving direction of the transmission component 42 is parallel to the arrangement direction of the drilling component 21 and the first riveting part 221. Preferably, the drilling driver 211 and the first riveting part 221 are respectively disposed on both sides of the drill bit component 212.

[0084] With the above configuration, the drilling assembly 21 and the first riveting part 221 are moved by the moving mechanism, so that when the drilling assembly 21 completes the drilling work, there is no need to move the tubular assembly 5. The drive assembly 41 drives the transmission assembly 42 to move, and moves the first riveting part 221 to the corresponding working position. Then, the pipe 51 and the accessory 52 are riveted by pressing. Preferably, the first riveting part 221 and the drill bit assembly 212 are adjacent to each other to shorten the length of the moving path of the transmission assembly 42.

[0085] In the embodiments of this application, the drive assembly 41 includes a drive motor and a lead screw that is driven and connected to the drive motor. The transmission assembly 42 includes a transmission part that is threadedly connected to the lead screw and a transmission table that is connected to the transmission part. The bottom of the transmission table is connected to the drilling assembly 21 and the first riveting part 221. The drive motor drives the lead screw to rotate and drives the transmission part to move along the axial direction of the lead screw, thereby driving the drilling assembly 21 and the first riveting part 221 to move, so that the drilling assembly 21 and the first riveting part 221 are selectively located directly above the corresponding riveting position of the tubular assembly 5.

[0086] In the embodiments of this application, the axial direction of the lead screw has an angle with the vertical direction; preferably, the axial direction of the lead screw is perpendicular to the vertical direction; more preferably, the first direction is the horizontal direction, and the axial direction of the lead screw is a second direction that is horizontal and orthogonal to the first direction.

[0087] In the embodiments of this application, the drive mechanism 4 includes a drive bracket 43, which is connected to the bottom wall of the working bracket 13. The drive assembly 41 and the transmission assembly 42 are both installed on the drive.

[0088] In the embodiments of this application, the drive bracket 43 is provided with at least one guide portion, which is a long strip parallel to the lead screw axis. The transmission component 42 includes a guide slider connected to the transmission table, and the guide slider is slidably connected to the guide portion. Preferably, the guide portion is slidably sleeved on the long strip guide portion.

[0089] In the embodiments of this application, the drive mechanism 4 includes a push component 44, which is mounted on the working bracket 13 and connected to the drive bracket 43. The push component 44 can drive the drive bracket 43 to move closer to the tubular component 5. Preferably, the push component 44 drives the drive bracket 43 to move in the vertical direction. When the drill bit component 212 or the first riveting part 221 is facing the tubular component 5, the push component 44 drives the drive bracket 43 to move and perform drilling or riveting work.

[0090] In the embodiments of this application, the pushing component 44 is a pneumatic device or a hydraulic device, which is connected to the middle region of the top wall of the drive bracket 43. The drive bracket 43 is connected to both sides along the second direction with auxiliary rods 45. The extension direction of the auxiliary rods 45 is parallel to the movement direction of the drive bracket 43. Each auxiliary rod 45 extends into the working bracket 13 through the corresponding auxiliary hole opened on the working bracket 13. Each auxiliary rod 45 is in relative movable contact with the hole wall of the corresponding auxiliary hole.

[0091] In the embodiments of this application, a barrier component 14 is provided on the workbench 12 to surround the perimeter of the workbench surface, and the barrier component 14 extends upward; by providing the barrier component 14, the waste generated by the drilling work is prevented from moving to the outside of the workbench 12, so as to keep the environment around the drilling and riveting equipment clean, and at the same time prevent the waste from splashing onto the workers.

[0092] In the embodiments of this application, the enclosure component 14 has a communication port on the side wall opposite to the first direction for the pipe 51 to pass through; by setting the communication port, the enclosure component 14 will not interfere with the installation of the pipe 51, so that the top height of the enclosure component 14 can be appropriately increased according to the actual situation, further improving the blocking effect on waste.

[0093] In the embodiments of this application, the method of using the drilling and riveting integrated equipment is as follows: The first step is to assemble the tubular component 51 with the first fixing component 31, assemble the second fixing component 32 with the accessory 52, and pre-assemble the accessory 52 with the tubular component 51 so that one of the riveting positions on the tubular component 5 is directly opposite the drill bit assembly 21. The second step is to turn on the drilling assembly 21 and drive the drive bracket 43 to move closer to the tubular assembly 5 by pushing the assembly 44, so that the drilling assembly 21 on the drive bracket 43 contacts the tubular assembly 5 and starts drilling. After the drilling assembly 21 completes the drilling, push the assembly 44 to drive the drive bracket 43 away from the tubular assembly 5 and turn off the drilling assembly 21. The third step is to activate the drive assembly 41, drive the transmission assembly 42 to move, and move the drilling assembly 21 and the first riveting part 221 to move, so that the first riveting part 221 is aligned with the drill hole on the tubular assembly 5; during the third step, the operator can place rivets into the drill hole. Fourth step, control the push component 44 to drive the drive bracket 43 to move closer to the tubular component 5, so that the first riveting part 221 on the drive bracket 43 moves towards the rivet. At the same time, the second riveting part 222 on the worktable 12 also moves towards the rivet under the drive of the corresponding driver. The first riveting part 221 and the second riveting part 222 cooperate to squeeze the rivet, so that the accessory 52 and the tube 51 are riveted together by the rivet. Then control the first riveting part 221 and the second riveting part 222 to reset, and then drive the transmission component 42 to reset through the drive component 41. Fifth step, tighten the adjusting nut 314 to reduce the clamping force between the first fixing component 31 and the tube 51, and then use external force to make the second extension 3222 and the tubular component 5 move in a spiral motion until the corresponding slider moves from one end of the spiral track to the other end, so that the other riveting position of the tubular component 5 is aligned with the drilling component 21. Then tighten the adjusting nut 314 in the opposite direction to make the first fixing component 31 clamp the tube 51. Step 6: Perform steps 2, 3 and 4 in sequence. Then, turn the adjusting nut 314 to separate the second fixing component 32 from the fitting 52 and remove the tubular component 5. This completes the drilling and riveting work of the fitting 52 and the pipe 51 of the tubular component 5.

[0094] In the embodiments of this application, the drilling and riveting mechanism 2 further includes a spraying assembly. The spraying assembly has an integrated flow channel for spraying water. The spraying assembly includes nozzles facing the riveting position of the tubular assembly 5. When the drilling assembly is performing drilling work, the spraying assembly sprays water synchronously to reduce the temperature of the tubular assembly and the drilling assembly, and prevent overheating from damaging the tubular assembly or the drilling assembly. Preferably, the working body has an integrated water tank and a pump for pumping water from the water tank into the flow channel. Another preferred embodiment is that the flow channel is connected to an external tap water pipe through a corresponding pipe.

[0095] In a specific embodiment of this application, during the drilling process, the pushing component 44 drives the drilling component 21 to perform reciprocating feed motion along the drilling direction.

[0096] Among them, reciprocating feed motion is a periodic motion that moves forward, backward, and then forward again along the drilling direction, and the forward movement distance is greater than the backward movement distance.

[0097] With the above settings, after the drill bit assembly 21 advances and processes a certain distance, the drilling assembly 21 is pushed back a certain distance by the push assembly 44, which can bring the drilled waste out of the hole and prevent the waste from getting stuck in the hole. In addition, the sprayed water can also enter the hole to cool the end of the drill bit assembly 21, thereby ensuring the stable operation of the drilling assembly 21.

[0098] In embodiments of this application, the spray assembly is installed on the side wall of the main housing in the first direction opposite side or on the worktable; or, the spray assembly is installed on the transmission assembly, so that the spray assembly and the drilling assembly move synchronously.

[0099] In the embodiments of this application, the drilling and riveting integrated equipment is equipped with a pipe support 6, which is arranged around the drilling and riveting integrated equipment to support the part of the pipe 51 located outside the drilling and riveting integrated equipment, ensuring that all parts of the pipe 51 are always coaxially arranged; preferably, each pipe support 6 is arranged on the opposite side of the first direction of the working body 1.

[0100] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
