Description

Technical Field

[0001] This application relates to the field of clamp technology, and in particular to a pipe clamp deformation correction device. Background Technology

[0002] Pipe clamps, as core connectors for the installation and fixation of automotive piping systems (such as fuel lines, brake lines, and coolant lines), directly affect the assembly stability and operational safety of automotive piping systems. During the production, processing, warehousing, transportation, or vehicle repair and disassembly of automotive pipe clamps, they are highly susceptible to defects such as twisting, warping, and deformation due to factors such as stamping errors, material impacts, environmental corrosion, and external forces during assembly and disassembly. If these clamps are directly used in assembly or continue to be used, it can lead to loosening of the automotive piping, resulting in pipe leaks, abnormal vibrations, and even failure, seriously threatening vehicle driving safety. Therefore, precise correction of deformed pipe clamps is necessary.

[0003] Currently, the automotive repair industry and pipe clamp manufacturers mostly use traditional manual hammering methods to correct deformed automotive pipe clamps. Operators use simple tools such as hammers and wrenches, relying on experience to hammer and straighten the deformed parts. This method has many inherent drawbacks, especially unsuitable for automotive pipe clamps with high precision requirements: First, the correction quality is extremely poor. Automotive pipe clamps are small in size and have a precise structure, making it difficult to accurately control the force and angle of manual hammering. This can easily lead to secondary deformation of the pipe clamp, or damage to the pipe clamp itself due to excessive hammering (such as cracks or deformation). It is impossible to guarantee the dimensional accuracy and assembly fit of the corrected pipe clamp, which is difficult to meet the high-precision assembly requirements of automotive piping. Second, the correction efficiency is extremely low. Correcting a single automotive pipe clamp requires a lot of manpower and time. Especially in automotive repair scenarios, there is often a need to correct multiple specifications and small batches of deformed pipe clamps, making the limitations of manual operation even more prominent and seriously restricting the repair progress. Third, the work intensity is high. Operators perform repetitive hammering actions for a long time, resulting in high labor intensity and easy fatigue, further exacerbating the instability of correction quality.

[0004] Furthermore, automotive pipe clamps are constantly exposed to complex environments such as engine compartments, which are humid, hot, and oily. Deformation is often accompanied by surface corrosion. Existing methods require separate rust removal using grinding tools, a cumbersome process that incurs additional manpower and equipment costs. Moreover, improper operation during rust removal can easily exacerbate pipe clamp deformation. The automotive industry has extremely high requirements for the assembly precision and reliability of parts. Existing methods for pipe clamp deformation correction and related treatments suffer from poor quality, low efficiency, high labor intensity, and high costs, making them unsuitable for the efficient and precise pipe clamp maintenance needs of the automotive production and repair sectors.

[0005] There is an urgent need for a device to correct the deformation of automotive pipe clamps that can solve the above problems. Utility Model Content

[0009] In some possible implementations, the quick-release part includes: a stop block with a through hole disposed within an opening; the opening is disposed at the end of one of the uprights, one end of the first mounting shaft is disposed within the opening, and the stop block is disposed on one side of the first mounting shaft; a quick-release bolt passing through the side wall of the upright near the opening and the through hole; wherein the first mounting shaft is rotatably connected to the inner wall of the opening and the stop block.

[0010] In some possible implementations, the hinge includes: a mounting plate spaced apart at the end of the upright away from the grip; and a hinge disposed between the mounting plate and the end of the upright; wherein the two ends of the hinge are respectively connected to the mounting plate and the upright.

[0012] In some possible implementations, the first transmission mechanism includes: a first gear and a second gear; wherein the first gear and the second gear are respectively sleeved on the outer circumferential wall of the base shaft near the end of the upright; the first gear and the second gear mesh.

[0013] In some possible implementations, the correction device further includes: a second transmission mechanism for replacing the first transmission mechanism during pipe clamp grinding; the second transmission mechanism includes: a first sprocket and a second sprocket, respectively sleeved on the outer circumferential wall of the base shaft near the end of the upright; a chain connected to the first sprocket and the second sprocket; a first sleeve and a second sleeve, both L-shaped; wherein the adjacent ends of the first sleeve and the second sleeve are sleeved together and distributed in a U-shape; one end of the first sleeve is connected to the outer wall of the upright; the end of the second sleeve away from the first sleeve is located on the side of the second sprocket; a positioning bolt abuts against the outer wall of the second sleeve through the outer wall of the first sleeve; a third sprocket rotatably located at the end of the second sleeve away from the first sleeve; wherein the third sprocket is connected to the outside of the chain.

[0014] One or more technical solutions provided in the embodiments of this utility model have at least the following technical effects or advantages: When the pipe clamp is deformed and needs to be corrected, the pipe clamp is placed between the first mounting shaft and the second mounting shaft, so that the outer wall of the pipe clamp abuts against the two sets of roller straightening groups. The rocker arm is shaken, causing the rocker arm to drive the second mounting shaft to rotate within the opening of the U-shaped support mechanism. The first transmission mechanism drives the first mounting shaft to rotate, and then the rotation directions of the first and second mounting shafts are opposite. When the rotation directions of the first and second mounting shafts are opposite, the movement directions of the adjacent sides of the first and second mounting shafts are the same. Then, the roller straightening groups installed on the first and second mounting shafts push the pipe clamp to move within the gap. The two sets of roller straightening groups roll the pipe clamp, thereby achieving the purpose of correcting the twisted pipe clamp.

[0015] Since the roller straightening group consists of multiple independently set roller units with different diameters, roller units of different diameters are selected according to the thickness of the pipe clamp, thereby achieving the purpose of adjusting the distance between the two roller straightening groups to adapt to pipe clamps of different thicknesses.

[0016] The working gap between the two sets of straightening rollers can be flexibly adjusted by simply replacing the roller unit, effectively adapting to the correction needs of pipe clamps of different thicknesses.

[0017] The first transmission mechanism enables the first and second mounting shafts to rotate synchronously in opposite directions, ensuring that the rolling pressure applied to the pipe clamp by the two sets of roller straightening groups is uniform and symmetrical, avoiding new deformation of the pipe clamp due to uneven force, and significantly improving the straightening accuracy and correction quality.

[0018] The device adopts a U-shaped support mechanism and a manual crank drive structure, which is not only compact and space-saving, but also easy to operate. It does not rely on a complex power system and can quickly carry out correction work in various scenarios such as on-site or workshop, thus improving work efficiency.

[0019] The line contact rolling method between the roller unit and the pipe clamp can effectively reduce wear on the pipe clamp surface and protect the surface quality of the pipe clamp compared with the traditional rigid pressing correction. It is especially suitable for the correction of pipe clamp products with high surface precision requirements. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this utility model can be understood according to the specific circumstances.

[0025] Example 1 Please see Figures 1-6 A pipe clamp deformation correction device includes: a support mechanism 100 and a roller assembly 200 mounted on the support mechanism 100; wherein the support mechanism 100 is U-shaped; the roller assembly 200 includes: a first mounting shaft 210a and a second mounting shaft 210b, which are spaced apart and installed in the opening 142 of the U-shaped support mechanism 100; two roller straightening groups 220 are provided, which are respectively sleeved on the circumferential outer walls of the first mounting shaft 210a and the second mounting shaft 210b; wherein the roller straightening group 220 is composed of multiple independently arranged roller units 221 with different diameters; a first transmission mechanism 300, which is connected at both ends to the first mounting shaft 210a and the second mounting shaft 210b respectively; and a rocker arm 500 is provided at the end of the second mounting shaft 210b away from the first transmission mechanism 300.

[0026] In the above embodiments, when the pipe clamp is deformed and needs to be corrected, the pipe clamp is placed between the first mounting shaft 210a and the second mounting shaft 210b, so that the outer wall of the pipe clamp abuts against the two sets of roller straightening groups 220 respectively. The rocker arm 500 is shaken, so that the rocker arm 500 drives the second mounting shaft 210b to rotate within the opening 142 of the U-shaped support mechanism 100. The first mounting shaft 210a is driven to rotate through the first transmission mechanism 300, and then the rotation directions of the first mounting shaft 210a and the second mounting shaft 210b are opposite. When the rotation directions of the first mounting shaft 210a and the second mounting shaft 210b are opposite, the movement directions of the adjacent sides of the first mounting shaft 210a and the second mounting shaft 210b are the same. Then, the roller straightening groups 220 installed on the first mounting shaft 210a and the second mounting shaft 210b push the pipe clamp to move within the gap. The two sets of roller straightening groups 220 roll the pipe clamp, thereby achieving the purpose of correcting the twisted pipe clamp.

[0027] Since the roller straightening group 220 is composed of multiple independently set roller units 221 with different diameters, roller units 221 with different diameters are selected according to the thickness of the pipe clamp, thereby achieving the purpose of adjusting the distance between the two roller straightening groups 220 to adapt to pipe clamps of different thicknesses.

[0028] The working gap between the two sets of straightening rollers can be flexibly adjusted by simply replacing the roller unit 221, effectively adapting to the correction needs of pipe clamps of different thicknesses.

[0029] The first transmission mechanism 300 enables the first mounting shaft 210a and the second mounting shaft 210b to rotate synchronously in opposite directions, ensuring that the rolling pressure applied to the pipe clamp by the two sets of roller straightening groups 220 is uniform and symmetrical, avoiding new deformation of the pipe clamp due to uneven force, and significantly improving the straightening accuracy and correction quality.

[0030] The device adopts a U-shaped support mechanism 100 and a manual crank 500 drive structure, which is not only compact and space-saving, but also easy to operate. It does not rely on a complex power system and can quickly carry out correction work in various scenarios such as on-site or workshop, thus improving work efficiency.

[0031] The line contact rolling method between the roller unit 221 and the pipe clamp can effectively reduce wear on the surface of the pipe clamp and protect the surface quality of the pipe clamp compared with the traditional rigid pressing correction. It is especially suitable for the correction of pipe clamp products with high surface precision requirements.

[0032] Example 2 Please see Figures 1-6The support mechanism 100 includes: two sets of uprights 110, which are V-shaped and spaced apart; wherein the first mounting shaft 210a and the second mounting shaft 210b are spaced apart between the two sets of uprights 110 along the extension direction of the uprights 110; a handle 120 is located between the two sets of uprights 110 and at one end of the uprights 110 away from the first mounting shaft 210a; and a support rod 130, which is L-shaped, with one end connected to the middle area of ​​the uprights 110 and the other end horizontally located on one side of the handle 120. The support mechanism 100 also includes a quick-release part 140 and a hinge part 150, which are respectively located at the ends of the two sets of uprights 110 near the first mounting shaft 210a; wherein the quick-release part 140 is detachably connected to the end of the first mounting shaft 210a away from the first transmission mechanism 300.

[0033] In the above embodiment, the two sets of uprights 110 and the gripping rod 120 form a U-shaped structure for mounting the first mounting shaft 210a and the second mounting shaft 210b. The end of the L-shaped support rod 130 away from the uprights 110 is located at the lower part of the first mounting shaft 210a and the second mounting shaft 210b, thereby supporting one side of the V-shaped uprights 110 through the support rod 130. The quick-release part 140 is detachably connected to the first mounting shaft 210a, so that when changing the roller unit 221 or loading the pipe clamp, the first mounting shaft 210a can be opened along the hinge part 150 by releasing the quick-release part 140 from the first mounting shaft 210a.

[0034] The support mechanism 100 adopts a combination of V-shaped uprights 110 and gripping rods 120 to form a U-shaped load-bearing structure, which, together with the triangular support design of L-shaped support rods 130, significantly improves the overall structural rigidity and stability of the device. It can effectively resist the rolling pressure and reaction force generated during the pipe clamp correction process, avoid deformation of the support or mounting shaft, and ensure the stability and consistency of the correction operation.

[0035] The coordinated design of the quick-release part 140 and the hinge part 150 enables the quick opening and closing function of the first mounting shaft 210a, which greatly reduces the difficulty of replacing the roller unit 221 and loading the pipe clamp, shortens the preparation time, and improves the overall operation efficiency. It is especially suitable for batch correction scenarios of multiple specifications of pipe clamps.

[0036] The quick-release structure design eliminates the need for destructive disassembly of the core components, reducing wear and tear on parts, extending the lifespan of the device, and lowering equipment maintenance costs.

[0037] The L-shaped support rod 130's position design does not interfere with the pipe clamp's feeding and correction operations, while also providing targeted support to the core load-bearing area. This balances structural stability with the rationality of the operating space, making the overall layout of the device more practical.

[0038] Example 3 Please see Figures 1-6 The quick-release part 140 includes: a stop 141 with a through hole, disposed in an opening 142; the opening 142 is disposed at the end of one of the uprights 110, one end of the first mounting shaft 210a is disposed in the opening 142, and the stop 141 is disposed on one side of the first mounting shaft 210a; a quick-release bolt 143, passing through the side wall of the upright 110 near the opening 142 and the through hole; wherein the first mounting shaft 210a is rotatably connected to the inner wall of the opening 142 and the stop 141.

[0039] In the above embodiment, when it is necessary to disassemble the quick-release part 140 to open the first mounting shaft 210a, the nut of the quick-release bolt 143 is removed, and the quick-release bolt 143 is taken out from the through hole. Then the stop block 141 is taken out from the opening 142, and the side of the opening 142 away from the upright 110 is opened, so that one end of the first mounting shaft 210a can be taken out from the opening 142.

[0040] It achieves reliable axial positioning of the first mounting shaft 210a and greatly simplifies the disassembly and assembly process. Compared with traditional threaded or snap-fit ​​connections, it can significantly shorten the quick disassembly time and improve the operational flexibility of the device.

[0041] The rotational connection between the first mounting shaft 210a and the inner wall of the opening 142 and the stop block 141 solves the adaptation problem between the quick-release limit and the shaft rotation, ensuring smooth power transmission during the correction operation, avoiding malfunctions such as jamming or abnormal noise, and ensuring the stability of the device operation.

[0042] The quick-release section 140 has simple and versatile components. The stop block 141 and quick-release bolt 143 are standard or easy-to-machine parts. If the parts wear out, they can be quickly replaced, reducing the maintenance cost and downtime of the equipment.

[0043] The matching design of the opening 142 and the stop 141 can form a radial positioning of the first mounting shaft 210a. Combined with the supporting role of the hinge part 150, it further improves the assembly coaxiality of the first mounting shaft 210a, avoids radial swaying of the shaft during rotation, and provides structural guarantee for the precise rolling straightening of the roller straightening group 220.

[0044] Example 4 Please see Figures 1-6 The hinge portion 150 includes: a mounting plate 151, spaced apart at one end of the upright 110 away from the grip 120; and a hinge 152, disposed between the mounting plate 151 and the end of the upright 110; wherein the two ends of the hinge 152 are respectively connected to the mounting plate 151 and the upright 110.

[0045] In the above embodiment, the mounting plate 151 is used to mount the end of the first mounting shaft 210a that is far away from the disassembly part. When the quick-release bolt 143 of the quick-release part 140 is removed, the first mounting shaft 210a drives the mounting plate 151 to swing along the axis of the hinge 152.

[0046] Example 5 Please see Figures 1-6 Both the first mounting shaft 210a and the second mounting shaft 210b include a mounting body; wherein the mounting body includes: a basic shaft 211, with two sets of uprights 110 rotatably connected to its two ends respectively; a sleeve 212, fitted onto the outer circumferential wall of the basic shaft 211; a limiting strip 213, disposed on the outer wall of the sleeve 212 along the axial direction of the sleeve 212; wherein the roller unit 221 is annular, and the inner wall of the annulus has a limiting groove that cooperates with the limiting strip 213; the roller unit 221 is fitted onto the outer circumferential wall of the sleeve 212; and multiple bearings 214 are provided, with the multiple bearings 214 respectively disposed at both ends of the basic shaft 211; the basic shaft 211 is rotatably connected to the uprights 110 through the bearings 214.

[0047] In the above embodiment, the basic shaft 211 has a polygonal cross-section, and the inner wall of the sleeve 212 has a hole that matches the polygonal cross-section of the basic shaft 211. This allows the rocker arm 500 to be connected to one end of the basic shaft 211, and rotating the rocker arm 500 can drive the sleeve 212 to rotate. When the sleeve 212 rotates, the limiting strip 213 on its surface drives the roller unit 221 with a limiting groove to rotate. It is worth noting that the basic shaft 211 can slide along the inner wall of the inner ring of the bearing 214, similar to the arrangement of the sleeve 212 and the roller unit. The connection method of element 221 is to connect the inner wall of the inner ring of bearing 214 to the outer wall of the end of basic shaft 211 through limiting strip 213. The grip rod 120 is composed of two sets of nested sleeve rods. The outer sleeve rod has a threaded hole on its circumferential outer wall. An adjusting bolt is set in the threaded hole. The end of the adjusting bolt abuts against the outer wall of the inner sleeve, so that the two sets of upright rods 110 can be opened by removing the adjusting bolt. When the two sets of sleeve rods slide, the distance between the two sets of upright rods 110 increases, and the roller unit 221 can be removed from one side of sleeve 212 for replacement.

[0048] Example 6 Please see Figures 1-6 The first transmission mechanism 300 includes a first gear 310 and a second gear 320; wherein the first gear 310 and the second gear 320 are respectively sleeved on the outer circumferential wall of the base shaft 211 near the end of the upright rod 110; the first gear 310 and the second gear 320 mesh.

[0049] In the above embodiment, the second gear 320 is sleeved on the end wall of the basic shaft 211 of the second mounting shaft 210b, so that when the basic shaft 211 of the second mounting shaft 210b is driven to rotate by the rocker arm 500, the second gear 320 is driven to rotate around the axis of the basic shaft 211. Since the second gear 320 meshes with the first gear 310, the rotation of the second gear 320 drives the first gear 310 to rotate, so that the rotation directions of the first mounting shaft 210a and the second mounting shaft 210b are opposite.

[0050] Example 7 Please see Figures 1-6 The correction device further includes: a second transmission mechanism 400, which is used to replace the first transmission mechanism 300 when grinding the pipe clamp; the second transmission mechanism 400 includes: a first sprocket 410 and a second sprocket 420, respectively sleeved on the outer circumferential wall of the base shaft 211 near the upright 110; a chain 430 connected to the first sprocket 410 and the second sprocket 420; a first sleeve 440 and a second sleeve 450, both L-shaped; wherein the first sleeve 440 is connected to the... The adjacent ends of the second sleeve 450 are sleeved together and arranged in a U-shape; one end of the first sleeve 440 is connected to the outer wall of the upright 110; the end of the second sleeve 450 away from the first sleeve 440 is located on one side of the second sprocket 420; the positioning bolt 460 passes through the outer wall of the first sleeve 440 and abuts against the outer wall of the second sleeve 450; the third sprocket 470 is rotatably located at the end of the second sleeve 450 away from the first sleeve 440; wherein the third sprocket 470 is connected to the outside of the chain 430.

[0051] In the above embodiments, when the surface of the pipe clamp is corroded, the surface of the pipe clamp can be polished by replacing the first transmission mechanism 300 with the second transmission mechanism 400. During the replacement process: As described in Embodiment 5, the adjusting bolts on the two sets of sleeves of the grip 120 are removed to facilitate the removal of the basic shaft 211 from the bearing 214. Then, the first gear 310 and the second gear 320 are removed, and the first sprocket 410 and the second sprocket 420 are respectively fitted onto the two sets of basic shafts 211. The chain 430 is then connected to the first sprocket 410 and the second sprocket 420. The grip 120 is then reset, and the third sprocket 470 is engaged with the outer side of the chain 430. The chain tension is adjusted by sliding the second sleeve 450 within the end wall of the first sleeve 440. After the tension adjustment is completed, the positioning bolt 460 axially fixes the second sleeve 450 and the first sleeve 440. The roller unit 221 on the first mounting shaft 210a is replaced with a friction wheel. When the rocker arm 500 drives the second mounting shaft 210b to rotate, the first mounting shaft 210a is driven to rotate in the same direction through the cooperation of the sprocket and the chain 430. This causes the friction wheel on the first mounting shaft 210a to move in the opposite direction to the adjacent side of the roller unit 221 on the second mounting shaft 210b, so that the friction wheel rotates in the opposite direction to the pipe clamp movement direction, thereby achieving the purpose of grinding and removing rust from the surface of the pipe clamp.

[0052] The device achieves modular upgrades and features a replaceable transmission mechanism, enabling it to perform both pipe clamp deformation correction and surface grinding and rust removal. This eliminates the need for additional dedicated equipment, significantly reducing investment costs and space requirements, and adapting to maintenance needs across multiple scenarios.

[0053] The 430 sprocket and chain drive offers superior adaptability. Compared to gear meshing, it provides higher transmission torque, is more impact-resistant, can stably bear grinding loads, and has a wide range of center distance adaptability, making it compatible with mounting shaft assembly errors.

[0054] The L-shaped sleeve tensioning structure allows for precise adjustment of the chain tension (430), effectively preventing slack and skipped teeth issues. It also accommodates chain wear and elongation, extending the lifespan of transmission components.

[0055] It works in close coordination with the preceding upright pole 110, handle pole 120 and other structures, and the transmission mechanism can be switched without disassembling the main body, making the operation convenient and efficient.

[0056] The reverse grinding design improves rust removal efficiency, while relying on the original roller support structure to avoid pipe clamp displacement or secondary deformation during grinding.
