Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an automatic direction finding tool for a coaxial pipe. Background Art

[0002] In the piping system of automobile air-conditioning compressors, coaxial pipes are usually arranged to meet different connection and operation requirements, that is, coaxially arranged pipes with different diameters are connected to each other, as shown in the attached figure. Figure 1 The initial structure of the existing coaxial tube to be processed is shown. At this time, a through hole 41 is opened on the side wall of the tube body. In addition, in order to adapt to the limited installation space in the car, the coaxial tube 4 needs to be adaptively bent later. Therefore, in order to ensure the processing quality of the coaxial tube 4, it is necessary to ensure that the position and orientation of the through hole 41 of the coaxial tube 4 before bending are accurate relative to the position and direction of the bending mold.

[0003] At present, there are many devices for bending pipes on the market, and the most common equipment is a pipe bending machine, which accurately clamps the pipe on the bending mold and realizes the bending of the pipe by the relative rotation of the bending mold. Therefore, when using the existing pipe bending machine to bend the above coaxial tube, it is necessary to ensure that the relative position and orientation of the through hole during clamping are accurate, so as to ensure that the processed bent coaxial tube can meet the product requirements. At this time, in the actual processing process, the coaxial tube is usually clamped by manual loading, that is, the operator holds the coaxial tube and places it on the bending mold, and limits the end through an end top plate set on one side of the bending mold to meet the positioning of the coaxial tube in the length direction. In addition, manual positioning is performed through a positioning pin set on the bending mold, that is, when loading, the positioning pin is manually inserted into the through hole on the coaxial tube to be processed to achieve positioning, and the positioning pin is manually returned after the positioning is completed. In order to ensure safety, the equipment will be paused during loading and positioning, and restarted after the positioning is completed. Since the positioning pin is manually inserted and returned and the equipment needs to be paused during the operation process, it is very easy to cause the coaxial tube to be processed to move during the operation, and the position state is prone to deviation. Therefore, it will greatly affect the processing quality and is not conducive to the industrial processing of the coaxial tube. Summary of the invention

[0030] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 7 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.

[0031] Figure 2 This is a structural diagram of an embodiment of an automatic direction-finding tool for coaxial tubes of the utility model; Figure 3 A structural diagram of a mobile station in a preferred embodiment of the utility model; Figure 4 This is a structural diagram of an axial adjustment assembly of a preferred embodiment of the utility model; Figure 5 This is a structural diagram of an angle adjustment assembly of a preferred embodiment of the utility model. Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the automatic orientation tooling for coaxial tubes provided in this embodiment is arranged on the head of the existing tube bending machine and is located beside the bending die, that is, the automatic orientation tooling for coaxial tubes 4 provided in this embodiment can be clamped by the bending die immediately after the coaxial tubes 4 to be processed are adjusted to an accurate state, thereby ensuring that the quality of the bent coaxial tubes 4 obtained after processing is better and the processing efficiency is higher. At this time, the automatic orientation tooling for coaxial tubes 4 provided in this embodiment includes: a moving platform 1, an axial adjustment component 2, and an angle adjustment component 3.

[0032] Specifically, the moving platform 1 includes an axial moving component 11, a lateral moving component 12 and an adjusting platform 13. During installation, the axial moving component 11 is installed on the head of the pipe bending machine, and the axial moving component 11 reciprocates along the feeding direction of the coaxial tube 4 to be processed, that is, when the coaxial tube 4 is fed along its axial direction, the movement direction of the axial moving component 11 is the axial direction of the coaxial tube 4, which realizes the axial position adjustment of the coaxial tube 4 to be processed, and meets the feeding requirements. In addition, the lateral moving component 12 is arranged on the axial moving component 11, and the lateral moving component 12 reciprocates along the feeding direction perpendicular to the coaxial tube 4 to be processed, so that the lateral moving component 12 can follow the movement of the axial moving component 11, and at the same time, it can also move perpendicular to the movement direction of the axial moving component 11, that is, the radial position adjustment of the coaxial tube 4 to be processed is realized, which also meets the feeding requirements. In addition, the adjusting table 13 is installed on the lateral moving component 12, so that the adjusting table 13 can move in two directions perpendicular to each other, so as to adjust the position of the coaxial tube 4 to be processed. This can not only facilitate the reception of the delivered coaxial tube 4, but also facilitate the subsequent orientation and clamping to the bending mold. The structure is more flexible, the processing is more convenient, and the processing efficiency is higher.

[0033] Specifically, the axial adjustment assembly 2 includes an axial adjustment driver 21 and an axial adjustment jaw 22. At this time, the axial adjustment driver 21 is fixedly installed on the adjustment table 13, so that the axial adjustment driver 21 can follow the movement of the adjustment table 13 to meet the subsequent fine-tuning processing requirements of the coaxial tube 4 to be processed. In addition, the axial adjustment driver 21 is arranged along the feeding direction of the coaxial tube 4 to be processed, that is, the axial adjustment driver 21 moves along the axial direction of the coaxial tube 4 to be processed, so that after the initial position adjustment is completed, the axial adjustment driver 21 can be used to further adjust the position of the coaxial tube 4 to be processed along its axial direction, so as to achieve accurate adjustment of the axial position and improve the processing accuracy. In addition, the axial adjustment jaw 22 is installed on the driving shaft of the axial adjustment driver 21, and the axial adjustment jaw 22 is driven by the movement of the axial adjustment driver 21 to move in the axial direction of the coaxial tube 4 to be processed.

In addition, the angle adjustment clamp 32 is installed on the rotating part of the rotating seat 31, so that the angle adjustment clamp 32 can rotate with the rotating part of the rotating seat 31. At this time, the clamping centers of the axial adjustment clamp 22 and the angle adjustment clamp 32 are both located on the rotation axis of the rotating part of the rotating seat 31, so that the coaxial tube 4 to be processed after axial adjustment by the axial adjustment clamp 22 can be clamped by the angle adjustment clamp 32, and it is ensured that the coaxial tube 4 will not be misaligned when clamped by the angle adjustment clamp 32. In addition, The rotating seat 31 can also drive the rotation of the axial adjustment jaw 22 to make the coaxial tube 4 to be processed rotate along its circumferential direction, so as to adjust the direction of the coaxial tube 4 to be processed, so that the position of the through hole 41 on the coaxial tube 4 can be more accurate before bending, which meets the automatic direction finding requirement of the coaxial tube 4 during the bending process, thereby ensuring the accuracy of the state of the coaxial tube 4 to be processed clamped in the bending mold later, which not only ensures the product processing quality, but also improves the processing efficiency, and better meets the industrial processing of the coaxial tube 4.

[0035] More specifically, a positioning component is also provided on the head of the pipe bending machine. At this time, the positioning component includes a proximity switch and a direct positioning member. During installation, the proximity switch and the direct positioning member are both installed on the head of the pipe bending machine and are located on the side of the movable platform 1 where the angle adjustment component 3 is provided, that is, the proximity switch and the diameter positioning member can also be located on the side of the coaxial tube 4 to be processed, which provides conditions for subsequent position monitoring of the coaxial tube 4 to be processed during adjustment. At this time, the proximity switch and the direct positioning member are both arranged toward the angle adjustment component 3 and the axial adjustment component 2, which provides conditions for subsequent monitoring of the state of the coaxial tube 4 to be processed during adjustment through the proximity switch and the direct positioning member. During use, the proximity switch is used to monitor whether the through hole 41 of the coaxial tube 4 to be processed reaches the predetermined position to achieve rough positioning, and then the direct positioning member is used to achieve fine positioning to meet the requirements of precise positioning, and the processing quality of the coaxial tube 4 is ensured by step-by-step positioning.

[0036] More specifically, the direct positioning member in the positioning assembly includes a positioning telescopic driver and a tapered pin. At this time, the positioning telescopic driver is fixedly installed on the head of the pipe bending machine to achieve the installation stability of the positioning telescopic driver. In addition, the positioning telescopic driver performs telescopic movement along the radial direction of the coaxial tube 4 to be processed. At the same time, the tapered pin is installed on the telescopic shaft of the positioning telescopic driver, so that when the positioning telescopic driver is in motion, the tapered pin can be driven to approach or move away from the coaxial tube 4 to be processed, that is, the tapered pin is inserted into the through hole 41 of the coaxial tube 4 to be processed to achieve accurate positioning, ensure that the position and orientation of the coaxial tube 4 to be processed can be more accurate, and ensure the processing quality of the coaxial tube 4.

At the same time, an external notch 3111 is provided at one end of the machine base 311 away from the adjustment platform 13, which provides conditions for the coaxial tube 4 to be processed later to be clamped by the angle adjustment clamp 32 on the rotating member. In addition, a main turntable 312 with an internal notch 3121 is also rotatably mounted on the machine base 311 and located at the external notch 3111, so that the main turntable 312 can rotate on the machine base 311, which provides conditions for the coaxial tube 4 to be processed to rotate when the main turntable 312 rotates later. At this time, the internal notch 3121 on the main turntable 312 is arranged along the radial direction of the main turntable 312, so that the internal notch 3121 can correspond to the axis of the main turntable 312, which provides conditions for the coaxial tube 4 to be processed in the internal notch 3121 to be arranged coaxially with the main turntable 312. In addition, the driving turntable 313 is rotatably installed on the machine base 311, and the driving turntable 313 is connected to the main turntable 312 by power, so that the driving turntable 313 can drive the main turntable 312 to rotate.

[0038] More specifically, the main turntable 312 and the driving turntable 313 of the rotating base 31 are gear structures, which realize the gear transmission between the main turntable 312 and the driving turntable 313, and improve the transmission stability and reliability. At the same time, a transmission gear 315 is also rotatably installed on the base 311. At this time, the transmission gear 315 is set between the main turntable 312 and the driving turntable 313, that is, the power transmission between the driving turntable 313 and the main turntable 312 is realized through the transmission gear 315, so as to meet the use requirements of deceleration and torque increase, and is more conducive to driving the circumferential rotation of the clamped coaxial tube 4.

[0039] More specifically, two transmission gears 315 are provided for transmitting the driving turntable 313 and the main turntable 312. During installation, the two transmission gears 315 are symmetrically arranged with the line connecting the axles of the main turntable 312 and the driving turntable 313 as the symmetry axis, thereby ensuring uniform force on the driving turntable 313 and the main turntable 312, making power transmission more stable and achieving better use effect.

[0040] More specifically, the center of the main turntable 312 is located inside one end of the outer notch 3111 and the inner notch 3121, that is, the outer notch 3111 and the inner notch 3121 are both penetrated to the center of the main turntable 312, so that the axis of the coaxial tube 4 clamped by the angle adjustment clamp 32 from the outer notch 3111 and the inner notch 3121 can coincide with the center of the main turntable 312, thereby ensuring that when the main turntable 312 rotates to realize the circumferential rotation of the coaxial tube 4, the coaxial tube 4 will not have the problem of positional displacement, thereby improving the accuracy of the position state. At the same time, the openings of the outer notch 3111 and the inner notch 3121 are arranged toward the side away from the adjustment platform 13, so that the openings of the outer notch 3111 and the inner notch 3121 will not be blocked, which facilitates the insertion of the coaxial tube 4 to be processed, and the structural design is more reasonable.
