Description

Technical Field

[0001] This invention relates to the field of automotive piping manufacturing, and more specifically to a riveting device for piping supports. Background Technology

[0002] An intake resonator is a technology in automotive intake systems that utilizes pressure fluctuations to improve charging efficiency. It consists of a resonant system comprised of pipes, a resonant box, and a resonant tube. Its core principle is to create a positive pressure wave by reflecting and superimposing negative pressure waves generated at the intake valve. At specific engine speeds, this positive pressure wave synchronizes with the valve cycle, increasing the pressure in the pipes and thus increasing the cylinder intake volume. This system optimizes performance across different engine speed ranges by adjusting parameters such as the resonant tube diameter, resonant box volume, and branch pipe length: a larger diameter improves high-speed performance, while a smaller diameter enhances low-speed performance; a large-volume resonant box broadens the engine speed range. The variable resonant system adapts to various operating conditions by dynamically adjusting parameters, improving low-speed torque and high-speed power. The resonant box also functions as a pressure regulator and buffer, reducing intake noise in the 400-600Hz frequency range by 3-5 decibels and storing buffer air to maintain idle stability. This technology precisely tunes the pressure wave phase to create a boost effect before the valve closes. Its design parameters, including the resonant tube length, diameter, and resonant chamber volume, directly affect the resonant frequency and engine intake efficiency. Some systems employ a variable pipe structure, using solenoid valves to control the intake pipe length and achieve full speed range optimization.

[0003] like Figure 1 and Figure 2 As shown, since both the pipe fitting 1 and the resonant box 2 need to be fixed, a bracket 3 is installed on the pipe fitting 1 and a mounting bracket 4 is installed on the resonant box 2. Both the bracket 3 and the mounting bracket 4 are provided with mounting holes 5. Fasteners (screws or rivets) are used to pass through the mounting holes 5 on the bracket 3 and the mounting bracket 4 to connect to the connecting seat on the car, so that the bracket 3 and the mounting bracket 4 are fixed to the car respectively.

[0004] Mounting bracket 4 is fixed to resonant box 2 by welding. Bracket 3 includes open sleeve 3a, first connecting plate 3b, second connecting plate 3c, and third connecting plate 3d. One end of open sleeve 3a is fixed to first connecting plate 3b, and the other end of open sleeve 3a is fixed to second connecting plate 3c. Third connecting plate 3d is fixed to second connecting plate 3c. Mounting hole 5 on bracket 3 is provided on third connecting plate 3d. Through hole 6 is provided on both first connecting plate 3b and second connecting plate 3c. Rivets are used to pass through the through hole 6 on first connecting plate 3b and second connecting plate 3c to fix first connecting plate 3b and second connecting plate 3c.

[0005] Currently, the method for installing bracket 3 onto pipe fitting 1 is as follows: the installer places the open sleeve 3a onto pipe fitting 1, then uses pliers to clamp the first connecting plate 3b and the second connecting plate 3c with one hand. Rivets are then passed through the through holes 6 on the first connecting plate 3b and the second connecting plate 3c, and a rivet gun is used to tighten the rivets, thus securing the first connecting plate 3b and the second connecting plate 3c. While this method secures bracket 3 to pipe fitting 1, it requires the operator to apply significant force with both hands, resulting in high labor intensity and fatigue after prolonged operation, leading to low production efficiency. Summary of the Invention

[0006] This invention provides a riveting device for pipe supports, which can reduce the labor intensity of operators and improve efficiency.

[0007] A pipe support riveting device includes a first support, a rivet gun, and a first positioning mechanism for restricting the degree of freedom of the pipe fitting, wherein the first positioning component is fixed to the first support. A second positioning mechanism for positioning the third connecting plate, wherein the second positioning component is fixed to the first support; A first support mechanism for supporting the resonant box, the first support mechanism being located on one side of the first support; A blocking seat that blocks the opening sleeve and the second connecting plate, the blocking seat being fixed to the first support; A linear drive mechanism is mounted on the first support. The pressure head is connected to the linear drive mechanism. After the linear drive mechanism drives the pressure head to apply pressure to the open sleeve and the first connecting plate, the first connecting plate, the second connecting plate and the open sleeve are clamped between the stop seat and the pressure head. An elastic suspension mechanism that suspends the rivet gun and causes it to rotate under pressure; the rivet gun is fixed to the elastic suspension mechanism.

[0008] In use, the operator applies a positive force to the handle, causing the second connecting seat to rotate clockwise. The second connecting seat transmits power to the first connecting rod, which pushes the slider to move linearly along the linear guide rail, thus feeding the pressure head towards the blocking seat. When the second connecting seat rotates and comes into contact with the first support, the open sleeve and the second connecting plate are clamped between the pressure head and the blocking seat, and the open sleeve is in close contact with the pipe. With the second connecting seat in contact with the first support, the linear drive mechanism keeps the pressure head in a holding position. The operator inserts a rivet through the through holes in the first and second connecting plates. The operator applies pressure to the rivet gun, causing the cantilever to rotate. After the working part of the rivet gun reaches the vicinity of the rivet, the operator controls the rivet gun to work, thereby securing the first and second connecting plates with the rivet, and thus the bracket clamps the pipe.

[0009] As can be seen from the above, the open sleeve is clamped between the pressure head and the stop seat. The clamping of the open sleeve no longer requires the operator to use pliers. The rivet gun is suspended by an elastic suspension mechanism. When using the rivet gun, the operator applies pressure to bring it close to the rivet, and then controls the rivet gun to engage with the rivet and begin operation. During the process of fastening the bracket to the pipe fitting, this structure of the present invention eliminates the need for the operator to lift the rivet gun or use pliers to clamp the bracket, thus freeing the operator's hands, greatly reducing the operator's labor intensity, and improving efficiency.

Detailed Implementation

[0019] like Figures 1 to 7 The present invention provides a riveting device for a pipe support, comprising a first support 11, a rivet gun 12, a first positioning mechanism, a second positioning mechanism, a first support mechanism, a blocking seat 13, a linear drive mechanism, and a pressing head 14. The components and their relationships are described below.

[0020] The first support 11 includes a workbench 11a, a base plate 11b, and a handle 11c. The workbench 11a is fixed to the base plate 11b, and the handle 11c is fixed to the base plate 11b. The entire riveting device can be moved by lifting.

[0021] The first positioning mechanism restricts the degree of freedom of the pipe fitting 1. The first positioning component is preferentially fixed on the worktable 11a of the first support 11. The first positioning mechanism includes a first support arm 15, a first mounting base 16, a first screw 17, and a first positioning plate 18 for positioning the axial degree of freedom of the pipe fitting 1. The first support arm 15 is suspended on the first support 11. In this embodiment, the first support arm 15 is fixed to the side wall of the worktable 11a by screws, so that the first support arm 15 is in a suspended state. When manufacturing the worktable 11a, since the first mounting base 16 is small in volume, it avoids making the worktable 11a larger to support the first mounting base 16, which helps to save costs and reduce the overall weight of the riveting device.

[0022] The first mounting base 16 is L-shaped and is preferably fixed to the first support arm 15 with screws. The first mounting base 16 has a first threaded hole, and a first screw 17 is threaded into the first threaded hole on the first mounting base 16. The first positioning plate 18 is connected to the first screw 17. In use, the axial end face of the pipe fitting 1 is brought into contact with the first positioning plate 18. Therefore, by rotating the first screw 17, the horizontal distance between the first positioning plate 18 and the first mounting base 16 is changed, thereby positioning pipe fittings 1 of different lengths.

[0023] The first positioning mechanism also includes a second mounting base 19, which is L-shaped and fixed to the first support arm 15. The second mounting base 19 has a groove 20 that mates with the pipe fitting 1 to restrict its radial degree of freedom. The groove 20 corresponds to the position of the first positioning plate 18. In this embodiment, the second mounting base 19 has a first oblong hole, and the first support arm 15 has a threaded hole. A screw passes through the first oblong hole on the second mounting base 19 and is threaded into the threaded hole on the first support arm 15, thereby securing the second mounting base 19 and the first support arm 15 together. Since the pipe fitting 1 is usually bent, the purpose of providing the first oblong hole on the second mounting base 19 is to allow adjustment of the position of the second mounting base 19. Therefore, after adjusting the position of the second mounting base 19, the groove 20 can be matched with different pipe fittings 1.

[0024] The second positioning mechanism positions the third connecting plate 3d, and the second positioning component is fixed to the first support 11. The second positioning mechanism includes a second support arm 21 and a third mounting base 22. The second support arm 21 is engaged with the lower surface of the worktable 11a. One end of the second support arm 21 is fastened to the worktable 11a by screws, and the other end of the second support arm 21 is located on the outside of the worktable 11a, so that the second support arm 21 is suspended on the first support 11. In the manufacturing of the worktable 11a, since the third mounting base 22 is small in size, this structure avoids making the worktable 11a larger to support the third mounting base 22, thereby saving costs and reducing the overall weight of the riveting device.

[0025] The third mounting base 22 is fixed to the second support arm 21. The third mounting base 22 is L-shaped. The third mounting base 22 is preferably fixed to the second support arm 21 with screws. The side of the third mounting base 22 is provided with a first groove 23. After the third connecting plate 3d is engaged with the first groove 23, it is positioned in the first groove 23 on the third mounting base 22. That is, the groove wall of the first groove 23 abuts against the third connecting plate 3d, thereby positioning the third connecting plate 3d.

[0026] like Figure 5 The first groove 23 has only three walls: the first groove wall 23a, the second groove wall 23b, and the third groove wall 23c. Figure 2 and Figure 5 The first groove wall 23a abuts against the right side of the third connecting plate 3d to position the third connecting plate 3d; the second groove wall 23b abuts against the lower side of the third connecting plate 3d to support and position the third connecting plate 3d; and the third groove wall 23c abuts against the rear side of the third connecting plate 3d to position the third connecting plate 3d. This structure facilitates the entry and exit of the third connecting plate 3d, improving the assembly or disassembly efficiency of the third connecting plate 3d and the third mounting base 22.

[0027] The first support mechanism supports the resonant box 2. The first support mechanism is located on one side of the first support 11 and includes a first support base 24. The first support base 24 has a notch 25 for the lower surface of the resonant box 2 to fit. Since the tube 1 and the resonant box 2 are fixed in advance, the support of the resonant box 2 by the first support mechanism prevents the resonant box 2 from falling under the action of gravity, thereby preventing the tube 1 from moving downward under the action of gravity.

[0028] A limiting block 42 is also fixed on the first support 11. The limiting block 42 limits the middle part of the pipe fitting 1 and is located below the second positioning mechanism. By limiting the pipe fitting 1 with the limiting block 42, the swaying of the pipe fitting 1 can be prevented, and the positional accuracy of the pipe fitting 1 can be further improved.

[0029] As can be seen from the above, since one end of the pipe 1 is positioned by the first positioning plate 18 and the other end of the pipe 1 is positioned by the resonant box 2, which is in turn positioned by the first support mechanism, the two ends of the pipe 1 along the axial direction are restricted and cannot move axially. Since the third connecting plate 3d is supported and positioned by the second positioning mechanism, the position of the bracket 3 is fixed, thereby improving the positional accuracy between the bracket 3 and the pipe 1. After the bracket 3 and the pipe 1 are fixed, the mounting hole 5 on the bracket 3 can accurately match the mounting part on the car.

[0030] The blocking seat 13 blocks the opening sleeve 3a and the second connecting plate 3c. The blocking seat 13 is fixed to the first support 11. The blocking seat 13 includes a first seat body 13a and a first stop block 13b. The first seat body 13a is preferably fixed to the workbench 11a with screws. The first stop block 13b is preferably integrally formed with the first seat body 13a, so that the first stop block 13b is fixed to the first seat body 13a. The first stop block 13b is provided with a mating surface. The mating surface includes a first arc-shaped surface 13c that mates with the opening sleeve 3a and a first flat surface 13d that mates with the second connecting plate 3c. That is, the first arc-shaped surface 13c blocks a part of the opening sleeve 3a, and the first flat surface 13d blocks the second connecting plate 3c.

[0031] In this embodiment, the linear drive mechanism is set on the workbench 11a of the first support 11. The linear drive mechanism includes a first connecting seat 26, a second connecting seat 27, a handle 28, a first connecting rod 29, a slider 30, and a linear guide rail 31. The first connecting seat 26 is fixed to the first support 11, the second connecting seat 27 is hinged to the first connecting seat 26, the handle 28 is fixed to the second connecting seat 27, one end of the first connecting rod 29 is hinged to the second connecting seat 27, and the other end of the first connecting rod 29 is hinged to the slider 30. The slider 30 is provided with a guide groove, and the guide groove on the slider 30 slides in cooperation with the linear guide rail 31. The pressure head 14 is fixed to the slider 30. Applying a positive force to the handle 28 causes the second connecting seat 27 to rotate. The second connecting seat 27 transmits power to the first connecting rod 29, which pushes the slider 30 to move linearly along the linear guide rail 31, thereby feeding the pressure head 14 toward the blocking seat 13. Since the blocking seat 13 has already blocked and supported the opening sleeve 3a and the second connecting plate 3c before the pressure head 14 feeds toward the blocking seat 13, when the second connecting seat 27 rotates and fits against the first support 11, the opening sleeve 3a and the second connecting plate 3c are pressed between the pressure head 14 and the blocking seat 13. At the same time, the first connecting rod 29 is in a straight state. Without applying a reverse force to the handle 28, the linear drive mechanism is in a locked state, so that the pressure head 14 will not loosen.

[0032] For different types of pipe fittings 1, the diameter of pipe fitting 1 is different. In order to make the pressing and riveting device of this embodiment applicable to the installation of more pipe fittings and brackets, the linear drive mechanism of this invention also includes a second screw 26a and a backstop mechanism for adjusting the position of the first connecting seat 26. The first connecting seat 26 is provided with a strip-shaped through hole 32, and the first support 11 is provided with a second threaded hole. The second screw 26a passes through the strip-shaped through hole 32 and is threadedly connected to the second threaded hole on the first support 11. The first connecting seat 26 is clamped between the first support 11 and the head of the second screw 26a. The length of the strip-shaped through hole 32 is greater than the diameter of the shank of the second screw 26a. Therefore, the position of the first connecting seat 26 can be moved to change the initial position of the first connecting seat 26, thereby changing the initial position of the second connecting seat 27, the first connecting rod 29, the slider 30 and the pressure head 14, and thus changing the initial position between the blocking seat 13 and the pressure head 14.

[0033] The anti-reverse mechanism includes a fixed base 33 and an adjusting screw 34. The fixed base 33 is fixed to the first support 11. The fixed base 33 is provided with a third threaded hole, and the adjusting screw 34 is threadedly connected to the third threaded hole. The adjusting screw 34 abuts against the first connecting seat 26. When the first connecting seat 26 is pressed against the first support 11 by the second screw 26a, the adjusting screw 34 presses against the first connecting seat 26, thereby preventing the position of the first connecting seat 26 from changing. This ensures the distance between the blocking seat 13 and the pressure head 14, which is beneficial for ensuring the quality of mass production of pipe fittings 1 and brackets 3 of the same model.

[0034] In addition to the structure described above, linear drive mechanisms can also employ linear actuators such as pneumatic cylinders or hydraulic cylinders.

[0035] The pressure head 14 is connected to a linear drive mechanism. After the linear drive mechanism drives the pressure head 14 to apply pressure to the open sleeve 3a and the first connecting plate 3b, a portion of the first connecting plate 3b, a portion of the second connecting plate 3c, and the open sleeve 3a are clamped between the stop seat 13 and the pressure head 14. The pressure head 14 includes a second seat 14a, a first pressure block 14b that engages with the first stop block 13b and applies pressure to the open sleeve 3a, and a second pressure block 14c that applies pressure to the open sleeve 3a and the first connecting plate 3b. The pressure block 14b is fixed to the second seat 14a, and the first pressure block 14b and the second pressure block 14c are respectively fixed to the second seat 14a. A groove 14d that mates with the open sleeve 3a is formed between the first pressure block 14b and the second pressure block 14c.

[0036] The inner surfaces of the first pressing block 14b and the second pressing block 14c facing each other are arc-shaped surfaces, and the inner surfaces of the second pressing block 14c facing the first pressing block 14b are composed of arc-shaped surfaces and flat surfaces. Therefore, a groove 14d that mates with the open sleeve 3a is formed between the first pressing block 14b and the second pressing block 14c. The length of the second pressing block 14c is greater than the length of the first pressing block 14b. Therefore, the second pressing block 14c can apply pressure not only to the open sleeve 3a, but also to the first connecting plate 3b.

[0037] The flexible suspension mechanism suspends the rivet gun 12 and allows it to rotate under pressure. The rivet gun 12 is fixed to the flexible suspension mechanism. By suspending the rivet gun 12 in the air through the flexible suspension mechanism, pressure is applied to the flexible suspension mechanism or the rivet gun 12 during use. This causes the flexible suspension mechanism to elastically deform, bringing the rivet gun 12 to the desired position. The force applied to the rivet gun 12 at this point is sufficient to hold it in that position. Because the flexible suspension mechanism generates a pulling force on the rivet gun 12, it remains suspended in the air. Therefore, when the rivet gun 12 is held in the desired position, the pressure applied by the operator to the rivet gun 12 is far less than the force required to hold the rivet gun 12 manually, thus greatly reducing the operator's workload.

[0038] The elastic suspension mechanism includes a spring seat 35, a spring 36, a rivet gun mounting base 37, a cantilever 38, and a cantilever support 39. The spring 36 is arranged with one end higher and the other end lower. One end of the spring 36 is connected to the spring seat 35, and the other end of the spring 36 is connected to the rivet gun mounting base 37. The rivet gun 12 is fixed to the rivet gun mounting base 37. The rivet gun mounting base 37 is fixed to one end of the cantilever 38, and the other end of the cantilever 38 is hinged to the cantilever support 39.

[0039] In this embodiment, the rivet gun mounting base 37 includes an upper clamp and a lower clamp, with the rivet gun 12 located between the upper and lower clamps. The upper and lower clamps are fastened together by bolts, thereby clamping the rivet gun 12. The support 39 includes a support plate 39a, a support column 39b, a first clamping plate 39c, and a second clamping plate 39d. One end of the support column 39b is fixed to the support plate 39a, and the other end of the support column 39b is hinged to the other end of the cantilever 38. The first clamping plate 39c and the second clamping plate 39d are respectively fixed to the support plate 39a. The first clamping plate 39c and the second clamping plate 39d clamp the support column 39b, thereby improving the stability of the support column 39b. The second clamping plate 39d is also fixed to a spring seat 35, which is fixed to the support plate 39a. The support plate 39a is provided with a waist-shaped hole 39e. Bolts are used to pass through the waist-shaped hole 39e and threadedly connect to the threaded hole provided on the base plate 11b, so that the support plate 39a and the base plate 11b are fixed as one unit. When facing pipe fittings 1 and brackets 3 of different sizes, the position of the elastic suspension mechanism can be adjusted as needed, thereby adjusting the position of the rivet gun 12.

[0040] The elastic suspension mechanism also includes a damping mechanism, which includes a support frame 40 and a damper 41 for cushioning the cantilever 38. The damper 41 is fixed to the support frame 40 and can be a gas damper or a liquid damper. The damper 41 cushions the cantilever 38 and also provides support, increasing the stability of the rivet gun 12 during operation.

[0041] The working process of this invention is as follows: S1, the linear drive mechanism is in the initial position, at which time the pressure head 14 is away from the blocking seat 13. The opening sleeve 3a is put on the tube 1, so that the tube 1 cooperates with the slot 20, the middle part of the tube 1 cooperates with the limiting block 42, so that the resonant box 2 cooperates with the notch 25 on the first support seat 24, and the first positioning plate 18 is adjusted by the first screw 17 so that the first positioning plate 18 abuts against the end of the tube 1.

[0042] S2, the opening sleeve 3a is combined with the first arc-shaped surface 13c, the second connecting plate 3c is combined with the first plane 13d, and the third connecting plate 3d is matched with the first groove 23, so that the bracket 3 is positioned and supported.

[0043] S3, the operator applies a positive force to the handle 28, causing the second connecting seat 27 to rotate forward. The second connecting seat 27 transmits power to the first connecting rod 29, which pushes the slider 30 to move linearly along the linear guide rail 31, thereby feeding the pressure head 14 toward the blocking seat 13. When the second connecting seat 27 rotates and fits against the first support 11, the opening sleeve 3a and the second connecting plate 3c are clamped between the pressure head 14 and the blocking seat 13. The opening sleeve 3a is in close contact with the pipe 1. When the second connecting seat 27 is in contact with the first support 11, the linear drive mechanism keeps the pressure head 14 in a holding position.

[0044] S4, the rivet is passed through the through hole 6 on the first connecting plate 3b and the second connecting plate 3c, that is, the rivet is pre-installed on the first connecting plate 3b and the second connecting plate 3c. When the operator applies pressure to the elastic suspension mechanism or the rivet gun 12, the pressure overcomes the tension of the spring 36 on the cantilever 38, causing the cantilever 38 to rotate. After the working part of the rivet gun 12 reaches the vicinity of the rivet, the operator fine-tunes the position of the rivet gun 12 to engage with the rivet. The operator controls the rivet gun 12 to work, thereby causing the rivet to fasten the first connecting plate 3b and the second connecting plate 3c, and then the bracket 3 clamps the pipe fitting 1.

[0045] S5, release the pressure on the elastic suspension mechanism, the elastic suspension mechanism resets under the action of spring 36, the operator applies a reverse force to handle 28, causing the second connecting seat 27 to reverse, the second connecting seat 27 transmits power to the first connecting rod 29, the first connecting rod 29 pulls the slider 30 to move linearly along the linear guide rail 31, thereby causing the pressure head 14 to move away from the blocking seat 13, releasing the pressure on the bracket 3, and the operator removes the assembled pipe fitting 1 and bracket 3.
