Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive oil pipe end stripping machines, and in particular to a novel clamping and rotating mechanism for automotive oil pipe end stripping machines. Background Technology
[0002] A small section (10mm) of nylon layer needs to be peeled off the end of the automotive brake hose. Hose sizes range from 4.76mm to 12mm. Loading and unloading can be done manually or automatically. The workflow involves manually or automatically inserting the hose. Once the hose is in place, a guide cylinder pushes forward to clamp it. Then, a motor starts rotating the hose while a laser peels off the nylon layer at the end. After peeling, the cylinder retracts, releasing the hose, which is then removed manually or by automated equipment. This process is repeated.
[0003] Currently, the new clamping and rotating mechanisms of automotive oil pipe end peeling machines all adopt a fork-like oblique push clamping structure for oil pipes. This structure is complex, difficult to manufacture, and has multiple support points and connection points, making it difficult to debug to a stable operating state. After clamping the oil pipe, this structure still needs to rotate. When pushing obliquely, the force surface and the contact rotation surface are in the same position, which causes friction during rotation. This leads to severe wear between the follower bearing and the rotating drum, seriously affecting the bearing life, production efficiency, product peeling effect quality, peeling size consistency, and even generating scrap.
[0004] To address the above issues, a novel clamping and rotating mechanism for an automotive oil pipe end stripping machine is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a novel clamping and rotating mechanism for an automotive oil pipe end stripping machine. This aims to improve upon the existing technology where the clamping and rotating mechanism of an automotive oil pipe end stripping machine uses a fork-like oblique push clamping structure. This structure is complex, difficult to manufacture, and has multiple support and connection points, making it difficult to achieve stable operation. Furthermore, this structure requires rotation after clamping the oil pipe. During oblique push, the force-bearing surface and the contact rotation surface are at the same position, causing friction during rotation. This leads to severe wear between the follower bearing and the rotating drum, seriously affecting bearing life, production efficiency, product stripping quality, and stripping size consistency, and may even result in defective products.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel clamping and rotating mechanism for an automotive oil pipe end stripping machine, comprising a mounting base, a rotating component on the top of the mounting base, and a clamping component on the outside of the rotating component;
[0007] The clamping assembly includes two support seats. The bottom of the support seats is fixedly connected to the top of the mounting base. A direct push assembly is provided on the top of the support seats. A tapered bearing is rotatably connected to the inner wall of the support seats. A rotating spindle is fixedly connected inside the tapered bearing. An inner tapered rotating sleeve is sleeved on the outer side of the rotating spindle. Multiple three-jaw linkages are rotatably connected to the outer side of the rotating spindle. A second pulley is fixedly connected to the outer side of the rotating spindle. A tapered three-jaw linkage is rotatably connected to the end of the three-jaw linkage away from the rotating spindle.
[0008] As a further description of the above technical solution:
[0009] The rotating assembly includes a motor, which is fixedly connected to the top of the mounting base on the outside, and a pulley is fixedly connected to the output end of the motor.
[0010] As a further description of the above technical solution:
[0011] The direct push assembly includes a guide rod cylinder, the outer side of which is fixedly connected to the top of the support base, and the output end of the guide rod cylinder is fixedly connected to a gantry bracket, with two conical followers rotatably connected to the inner side of the gantry bracket.
[0012] As a further description of the above technical solution:
[0013] Oil pipes are provided between the multiple conical three-jaw jacks.
[0014] As a further description of the above technical solution:
[0015] The outer side of the inner conical rotating sleeve is located on the outer side of the multiple conical three-jaw jacks.
[0016] As a further description of the above technical solution:
[0017] The outer side of the inner conical rotating sleeve is located on the outer side of the support base.
[0018] As a further description of the above technical solution:
[0019] The second pulley is connected to the first pulley by a belt.
[0020] As a further description of the above technical solution:
[0021] The pushing force-bearing surface in the middle of the inner conical rotating sleeve and the conical follower are in inclined contact.
[0022] This utility model has the following beneficial effects:
[0023] In this invention, a portal frame bracket is installed at the front end of a double-rod cylinder instead of a fork, and a direct push method is used to move the portal frame bracket forward, driving the conical follower. The inner conical rotating sleeve contacts the inclined surface of the conical follower, pushing the inner conical rotating sleeve, which in turn links the three-jaw connecting rod and the conical three-jaw, so that the conical three-jaw tightly clamps the oil pipe. This achieves smooth and noiseless rotation with almost no friction, greatly improving stability. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a novel clamping and rotating mechanism for an automotive oil pipe end stripper, comprising a mounting base 1, a rotating component on the top of the mounting base 1, and a clamping component on the outside of the rotating component.
[0031] The clamping assembly includes two support seats 13. The bottom of the support seat 13 is fixedly connected to the top of the mounting base 1. A direct push assembly is provided on the top of the support seat 13. A tapered bearing 14 is rotatably connected to the inner wall of the support seat 13. A rotating spindle 5 is fixedly connected inside the tapered bearing 14. An inner tapered rotating sleeve 6 is sleeved on the outer side of the rotating spindle 5. Multiple three-jaw connecting rods 4 are rotatably connected to the outer side of the rotating spindle 5. A pulley 12 is fixedly connected to the outer side of the rotating spindle 5. A tapered three-jaw jack 3 is rotatably connected to the end of the three-jaw connecting rod 4 away from the rotating spindle 5.
[0032] Specifically, the mounting base 1 is used to support the upper components and ensure machining accuracy. Its top rotating component is the power source, driving the oil pipe 2 to rotate and assist in peeling. The clamping component in the rotating component is used to clamp the oil pipe 2. The two support seats 13 are both load-bearing and positioning components, ensuring the clamping process. The direct push component is used to drive the operation of subsequent components. The tapered bearing 14 provides a smooth rotation environment for the rotating spindle 5, reducing frictional resistance during rotation and ensuring that the rotating spindle 5 can rotate stably and efficiently. The rotating spindle 5 is the rotation hub. The inner tapered rotating sleeve 6 plays a transitional and synergistic role, optimizing force transmission and ensuring smooth operation. The three-jaw connecting rod 4 is like a joint connector, converting rotational power to control the tapered three-jaw 3 to grip the oil pipe 2. The pulley 12 on the rotating spindle 5 is the key link for power transmission, accurately connecting the power to the spindle. The tapered three-jaw 3 clamps the oil pipe 2 tightly with its tapered design. In conjunction with the direct push and rotating components, it prevents the oil pipe 2 from loosening and shifting during peeling, ensuring high-precision machining.
[0033] Reference Figure 1 - Figure 3 The rotating assembly includes a motor 10, which is fixedly connected to the top of the mounting base 1 on the outside. A pulley 11 is fixedly connected to the output end of the motor 10.
[0034] Specifically, the motor 10 drives the rotating shaft 11 to rotate, thereby realizing the rotation function of the rotating component. The mounting base 1 provides stable support to ensure that the motor 10 and the pulley 11 can operate stably.
[0035] Reference Figure 1 - Figure 3 The direct push assembly includes a guide rod cylinder 9, which is fixedly connected to the top of the support base 13 on the outside. A portal frame 8 is fixedly connected to the output end of the guide rod cylinder 9, and two conical followers 7 are rotatably connected to the inside of the portal frame 8.
[0036] Specifically, the guide rod cylinder 9 drives the gantry bracket 8 to move linearly using air pressure. The gantry bracket 8 supports and guides the movement of the conical follower 7. With the rotational cooperation within the gantry bracket 8, the conical follower 7 can achieve precise clamping action. Through coordination with other components, it completes the precise clamping and positioning of the object to be processed.
[0037] Reference Figure 1 - Figure 3 Oil pipes 2 are provided between multiple conical three-jaw 3. The outer side of the inner conical rotating sleeve 6 is provided on the outer side of multiple conical three-jaw 3. The outer side of the inner conical rotating sleeve 6 is provided on the outer side of the support seat 13. The belt connects the second pulley 12 and the first pulley 11. The middle pushing force surface of the inner conical rotating sleeve 6 is in inclined contact with the conical follower 7.
[0038] Specifically, oil pipe 2 is used to provide lubricating oil to ensure that the conical three-jaw 3 reduces friction and extends service life during operation. The inner conical rotating sleeve 6 serves as a rotation guide and works with the conical three-jaw 3 to achieve rotation and clamping functions. Support seat 13 provides stable support to ensure that the inner conical rotating sleeve 6 can rotate accurately. Belt pulley 2 12 is connected to belt pulley 11 and is used to transmit power to drive the inner conical rotating sleeve 6 to rotate. The push force receiving surface in the middle of the inner conical rotating sleeve 6 is in inclined contact with the conical follower 7. The inclined contact method can effectively transmit thrust, and at the same time, the rotation is smooth and noiseless with almost no friction, which greatly improves stability.
[0039] Working principle: First, the guide rod cylinder 9 of the direct push assembly is activated, pushing the gantry bracket 8 forward, which drives the conical follower 7. With the help of the inner conical rotating sleeve 6 contacting the inclined surface of the conical follower 7, the inner conical rotating sleeve 6 is pushed, which in turn links the three-jaw connecting rod 4 and the conical three-jaw 3, so that the conical three-jaw 3 tightly clamps the oil pipe 2, achieving smooth and noiseless rotation with almost no friction, greatly improving stability. Next, the motor 10 of the rotating assembly starts to work, and the power is transmitted to the first pulley 11 through the output end, and then drives the second pulley 12 and the rotating main shaft 5 fixed thereto to rotate through the belt, finally realizing the stable rotation of the clamped oil pipe 2. At this time, with the help of external laser equipment, the nylon layer at the end of the oil pipe 2 can be precisely peeled off. This cycle is repeated, efficiently, stably and accurately processing the end of the automotive oil pipe 2, meeting the needs of auto parts production.
