Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, and more specifically, it relates to a universal pipe cutting device for automotive flexible and rigid pipes. Background Technology

[0002] Automotive hoses and flexible hoses play a crucial role in connection and transmission in various vehicle systems, with a wide range of applications. Rigid hoses, with their high strength and stability, are mostly used in engine fuel supply systems, braking systems, air conditioning lines, and other parts that need to withstand high pressure, high temperature, or ensure the rigidity of the pipeline; while flexible hoses are characterized by their flexibility and are suitable for scenarios that need to adapt to vibration and displacement.

[0003] Currently, the engine cooling system connects the water tank and the engine via a flexible hose. However, it is not easy to install a flexible hose on a car. The flexible hose needs to be assembled with a rigid hose, and then the combined flexible and rigid hose is installed on the car. Before the flexible and rigid hoses are assembled, the flexible and rigid hoses need to be cut. The hose is cut to the required length using a hose cutting machine to facilitate the subsequent use of the hose.

[0004] However, due to the influence of the materials of soft and hard tubes, existing soft and hard tubes are all cut using their corresponding tube cutting machines, that is, soft and hard tubes are cut separately. This cutting method increases the complexity of the work and is not conducive to the subsequent assembly of soft and hard tubes. Now, a universal tube cutting device for automotive soft and hard tubes is proposed to improve the existing problems. Utility Model Content

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] Please see Figures 1-4 The present invention provides the following technical solution: Example 1, see Figure 1 A universal pipe cutting device for automotive flexible and rigid pipes includes a placement component 1, a pipe cutting component 2 is disposed above the placement component 1, and a workpiece 3 is disposed on one side of the pipe cutting component 2.

[0024] In practical applications, the workpiece 3 can be either a soft or hard tube. The placement component 1 is used to place the workpiece 3, and the tube cutting component 2 cuts the workpiece 3 placed on the placement component 1 to complete the cutting process of the workpiece 3.

[0025] The specific structure of component 1 is as follows: See Figure 2 The placement component 1 includes a workbench 11, on which a first placement structure 12, a second placement structure 13, and a third placement structure 14 are sequentially arranged, and the workpiece 3 is placed in the middle position of the first placement structure 12.

[0026] The first placement structure 12 is installed on the side wall of the workbench 11 via a connecting plate. The first placement structure 12 includes a base, a spring rod, and a limiting seat. The spring rod is located on the top of the base and adjusts the position of the workpiece 3 during cutting. The limiting seat is set as a V-shaped structure, and the shape of the limiting seat is adapted to the shape of the workpiece 3. During the cutting process, the limiting seat can provide support for the workpiece 3.

[0027] When the pipe cutting assembly 2 cuts the workpiece 3, the workpiece 3 will move downward due to the pressure. At this time, the first placement structure 12 adapts to the position change of the workpiece 3.

[0028] The shapes of the second placement structure 13 and the third placement structure 14 are the same as those of the first placement structure 12. By setting the first placement structure 12, the second placement structure 13, and the third placement structure 14, it is easy to adapt to the cutting process of the workpiece 3.

[0029] In addition, a tube conveying mechanism is provided on the side of the first placement structure 12 away from the worktable 11. The tube conveying mechanism consists of two sets of conveying rollers and a conveying motor. Driven by the conveying motor, the two sets of conveying rollers can convey the workpiece 3 to the position of the first placement structure 12.

[0030] See Figure 4 The placement component 1 also includes a drive motor 17, a partition 19 is provided on one side of the drive motor 17, and the output end of the drive motor 17 is connected to the first transmission structure 16 through the partition 19.

[0031] An electric chuck 15 is rotatably connected to the partition 19. The first transmission structure 16 is sleeved on the outside of the electric chuck 15, and the workpiece 3 is disposed through the middle position of the electric chuck 15.

[0032] The first transmission structure 16 comprises a first driving wheel, a first driven wheel, and a synchronous belt. The output end of the drive motor 17 passes through the partition 19 and is connected to the first driving wheel. The synchronous belt is sleeved on the outside of the first driving wheel and the first driven wheel. The electric chuck 15 passes through the center of the first driven wheel and is rotatably connected to the partition 19. The inner sidewall of the first driven wheel is fixedly connected to the outer sidewall of the electric chuck 15.

[0033] In practical applications, the drive motor 17 is started, which drives the first transmission structure 16 to rotate. Under the drive of the first transmission structure 16, the electric chuck 15 rotates accordingly.

[0034] The electric chuck 15 is an automated clamping device driven by electricity. The electric chuck 15 includes a clamping motor, a jaw, and a housing. The clamping motor can drive the movement of the jaw to clamp the workpiece 3. The outer wall of the housing is fixedly connected to the inner wall of the first driven wheel.

[0035] Two sets of limiting mechanisms 18 are symmetrically arranged on one side of the electric chuck 15, and the two sets of limiting mechanisms 18 are respectively arranged on both sides of the workpiece 3.

[0036] See Figure 3 The limiting mechanism 18 includes an electric slide rail 181, a placement block 182 is slidably connected above the electric slide rail 181, and a telescopic cylinder 183 is provided on the top of the limiting mechanism 18.

[0037] The output end of the telescopic cylinder 183 is connected to a placement frame 184, and a limit roller 185 is rotatably connected to the middle position of the placement frame 184.

[0038] The working principle of the electric slide rail 181 is to use a motor to provide power, and convert the rotational motion of the motor into linear motion through a reducer, synchronous belt and ball screw, so as to drive the slider on the slide rail to move along the track. The top of the slider is provided with a placement block 182. By starting the electric slide rail 181, the electric slide rail 181 can drive the placement block 182, telescopic cylinder 183, placement frame 184 and limit roller 185 to move horizontally as a whole.

[0039] After the workpiece 3 is conveyed to the position of the first placement structure 12, it passes through the partition 19 and the electric chuck 15 in sequence to reach the positions of the second placement structure 13 and the third placement structure 14. The workpiece 3 can be limited by two sets of limiting mechanisms 18. The workpiece 3 can be placed in a horizontal position by the cooperation of the electric chuck 15 and the two sets of limiting mechanisms 18, which is suitable for cutting soft and hard pipes.

[0040] In addition, since the limiting roller 185 is rotatably connected to the placement frame 184, when the drive motor 17 drives the electric chuck 15 and the workpiece 3 to rotate through the first transmission structure 16, the workpiece 3 is adapted to its rotation by the two sets of limiting rollers 185, which facilitates the normal operation of the cutting work.

[0041] In practical applications, when the workpiece 3 reaches the position of the limiting mechanism 18, the telescopic cylinder 183 is activated. The placement frame 184 and the limiting roller 185 approach the workpiece 3 under the drive of the telescopic cylinder 183. Due to the setting of two sets of limiting rollers 185, the two sets of limiting rollers 185 can limit the workpiece 3.

[0042] Meanwhile, depending on the length of the cut tube, the position of the limiting roller 185 can be adjusted by the electric slide rail 181, which is suitable for cutting the workpiece 3 at different positions.

[0043] See Figure 2 The pipe cutting assembly 2 includes a cutting motor 21. The output end of the cutting motor 21 is connected to a second transmission structure 22. A cutter 24 is provided at the end of the second transmission structure 22 away from the cutting motor 21. A drive cylinder 23 is provided below the second transmission structure 22 and is hinged to the second transmission structure 22.

[0044] See Figure 2 An auxiliary structure 25 is provided on one side of the drive cylinder 23. The auxiliary structure 25 is located on the top of the worktable 11 and is hinged to the bottom of the second transmission structure 22.

[0045] The second transmission structure 22 includes a second drive wheel, a second driven wheel, a transmission chain, and a housing. The transmission chain is sleeved on the outside of the second drive wheel and the second driven wheel. The housing is provided on the outside of the transmission chain. The output end of the cutting motor 21 is connected to the second drive wheel. The cutter 24 is connected to the second driven wheel. The outside of the housing is hinged to the output end of the drive cylinder 23. The bottom of the housing is hinged to the auxiliary structure 25.

[0046] The cutting motor 21 drives the second driven wheel of the second transmission structure 22 to rotate, which in turn drives the cutter 24 to rotate. The cutter 24 can cut the workpiece 3 at high speed.

[0047] Start the drive cylinder 23, which can drive the second transmission structure 22 to swing along the auxiliary structure 25. The position of the cutter 24 can be adjusted by the drive cylinder 23 so that the cutter 24 is suitable for cutting the workpiece 3.

[0048] If workpiece 3 is a flexible tube, and the tube length is extended to the position of the third placement structure 14, the specific tube cutting process is as follows: First, the workpiece 3 is transported by the tube conveying mechanism and placed on the first placement structure 12, the second placement structure 13, and the third placement structure 14. The worktable 11 starts the electric chuck 15 to clamp the workpiece 3. Then, the two sets of electric slide rails 181 are started to drive the limiting rollers 185 to move to the two sets of workpiece 3 respectively. Then, the two sets of telescopic cylinders 183 are started respectively, and the two sets of telescopic cylinders 183 drive the two sets of limiting rollers 185 to move towards each other. The two sets of limiting rollers 185 limit the workpiece 3. Then, the cutting motor 21 and the drive motor 17 are started respectively. The cutting motor 21 drives the cutter 24 to rotate, and the drive motor 17 drives the electric chuck 15 and the workpiece 3 to rotate. Then, the drive cylinder 23 is started. Under the drive of the drive cylinder 23, the cutter 24 approaches the workpiece 3 and cuts the workpiece 3 while rotating.

[0049] If workpiece 3 is a rigid tube, the operation method is the same. If the cutting length of workpiece 3 is changed, the limiting position of workpiece 3 by the two sets of limiting mechanisms 18 can be adjusted to match the cutting length.

[0050] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
