TECHNICAL FIELD

[0001] The present application relates to the field of air conditioner parts processing technology, in particular to an air conditioner pipe pressing plate direction selection method. BACKGROUND

[0002] In the processing of air conditioner pipes, the pressing plate is usually fixed to one end of the air conditioner pipe by other equipment processes. When the air conditioner pipe is subsequently bent, a fixed angle is required between the bending plane of the air conditioner pipe and the pressing plate, so that the air conditioner pipes with the same batch of pressing plates are the same in bending direction and pressing plate direction.

[0003] However, the pipe with the pressing plate can only be manually placed in the profiling block of the pipe bending machine for bending processing, and can only be manually fed and discharged, which cannot realize automatic feeding and discharging and automatic direction selection. SUMMARY

[0004] The purpose of the present application is to provide an air conditioner pipe pressing plate direction selection method which can be matched with automatic feeding and discharging equipment, increase production efficiency and automation degree, and has high consistency in pressing plate direction.

[0005] To solve the above technical problems, the present application provides an air conditioner pipe pressing plate direction selection method, comprising the following steps:

[0006] Step one, fix the pipe at the clamping and rotating mechanism, and make the end of the pipe with the pressing plate abut against the positioning block for axial positioning;

[0007] Step two, rotate the pipe along the circumference by the clamping and rotating mechanism, and then rotate the pressing plate by the pipe;

[0008] Step three, rotate the pressing plate to the detection position of the inductor, so that the inductor detects the orientation of the pressing plate, and then drives the inductive block to move close to the pipe;

[0009] Step four, stop the inductive block after moving a distance, and make the pressing plate contact the inductive block during continuous rotation, and stop the rotation of the clamping and rotating mechanism to the pipe.

[0010] Further, the clamping and rotating mechanism includes a rotating support seat and a rotatable air claw provided on the rotating support seat. When the pipe is fixed at the clamping and rotating mechanism, the air claw clamps the end of the pipe away from the pressing plate.

[0011] Further, a rotating shaft is provided through the rotating support seat, and one end of the rotating shaft is connected with the air claw.

[0012] Further, the clamping and rotating mechanism further includes a driving member, and the output end of the driving member is connected with the rotating shaft through a shaft coupling.

[0013] Further, the rotating support base is fixed on the adjusting base, and the adjusting base is movably connected on the adjusting track.

[0014] Further, the inductor and the induction block are arranged on two sides of the pipe in the circumferential direction, when the pipe is arranged on the clamping and rotating mechanism and one end of the pressing plate abuts against the positioning block, the distance between the induction block and the pipe is greater than the length of the pressing plate, when the pressing plate rotates to the detection position of the inductor, the induction block approaches the pipe, so that the pressing plate contacts the induction block during the rotation.

[0015] Further, the inductor is a fiber inductor.

[0016] Further, the induction block is a contact inductor.

[0017] Further, the pipe has a bracket on the lower side.

[0018] Further, the bracket is movably arranged on the bottom track.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0030] It can be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of one element can be one, and in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as a limitation on the number.

[0031] As Figures 1-4 described, the present application provides a pipe pressing plate direction selection method for an air conditioner, comprising the following steps:

[0032] Step one, fix the pipe 2 at the clamping and rotating mechanism 1, and make the pipe 2 with one end of the pressing plate 3 abutting against the positioning block 4 to be axially positioned;

[0033] Step two, rotate the pipe 2 along the circumference through the clamping and rotating mechanism 1, and then rotate the pressing plate 3 through the pipe 2;

[0034] Step three, rotate the pressing plate 3 to the detection position of the inductive piece 5, so that the inductive piece 5 detects the orientation of the pressing plate 3, and then drives the inductive block 6 to move close to the pipe 2;

[0035] Step four, stop the inductive block 2 after moving a distance, and make the pressing plate 3 contact the inductive block 6 in the process of continuous rotation, and stop the rotation of the pipe 2 driven by the clamping and rotating mechanism 1.

[0036] In particular, the inductive piece 5 and the inductive block 6 are arranged on both sides of the pipe 2 in the circumference, when the pipe 2 is placed at the clamping and rotating mechanism 1 and the one end of the pipe 2 with the pressing plate 3 abuts against the positioning block 4, the distance between the inductive block 6 and the pipe 2 is greater than the length of the pressing plate 3, when the pressing plate 3 rotates to the detection position of the inductive piece 5, the inductive block 6 moves close to the pipe 2, so that the pressing plate 3 contacts the inductive block 6 in the process of rotation.

[0037] When the orientation of the pressing plate needs to be selected and positioned, the pipe fitting with one end fixedly connected with the pressing plate is placed at the clamping and rotating mechanism for clamping and fixing, and the end of the pipe fitting with the pressing plate is abutted against the position of the positioning block, so that the positioning block limits the axial position of the pipe fitting, thereby ensuring that the pressing plate can be detected by the inductor and the induction block, then the clamping and rotating mechanism is started to drive the pipe fitting to rotate circumferentially, and the pressing plate rotates circumferentially synchronously with the pipe fitting, in the process of rotating the pressing plate, when the pressing plate rotates to the detection position of the inductor, the induction block is started to move to the position of the pipe fitting, thereby reducing the distance between the induction block and the pipe fitting, when the induction block stops moving, the distance between the induction block and the pipe fitting is less than the length of the pressing plate, so that the pressing plate will contact the position of the induction block in the process of continuing to rotate, then the induction block transmits a signal to control the clamping and rotating mechanism to stop rotating when contacting the pressing plate, so that the pressing plate remains in the orientation just contacting the induction block, thereby accurately realizing the orientation selection operation of the pressing plate, ensuring that the orientations of the pressing plates on each pipe fitting are consistent, thereby increasing the consistency of the fixed angle between the orientation of the pressing plate and the bending plane of the pipe fitting.

[0038] In the process of rotating the pressing plate, when the pressing plate rotates to the detection position of the inductor, the induction block moves to the position of the pipe fitting, thereby reducing the distance between the induction block and the pipe fitting, when the induction block stops moving, the distance between the induction block and the pipe fitting is less than the length of the pressing plate, so that the pressing plate will contact the position of the induction block in the process of continuing to rotate, then the induction block transmits a signal to control the clamping and rotating mechanism to stop rotating when contacting the pressing plate, so that the pressing plate remains in the orientation just contacting the induction block, thereby accurately realizing the orientation selection operation of the pressing plate, ensuring that the orientations of the pressing plates on each pipe fitting are consistent, thereby increasing the consistency of the fixed angle between the orientation of the pressing plate and the bending plane of the pipe fitting.

[0039] In particular, in the process of detecting the position of the pressing plate by the inductor and moving the induction block close to the pipe fitting, the induction block is driven to displace by the air cylinder, hydraulic cylinder or the like, and when the induction block moves to the stop position, the air cylinder, hydraulic cylinder or the like is also used to stop the movement and fix the current position, and the specific stop position can be set in advance by the operator, thereby adjusting the orientation angle of the pressing plate.

[0040] It is worth mentioning that the orientation device used in the scheme is suitable for the pipe fitting fixedly connected with the pressing plate, and the pressing plate is fixed to the pipe fitting at one end of the pipe fitting by welding, riveting or the like, so as to avoid the problem that the orientation result is inaccurate due to the movement of the pressing plate relative to the pipe fitting.

[0041] In an embodiment of the present scheme, when the orientation selection device determines the orientation of the pressing plate, the pipe is moved to the bending machine device by a moving device such as a mechanical hand or a mechanical arm. Since the moving device such as the mechanical hand or the mechanical arm does not change the angle of the pressing plate during the movement of the pipe, the bending plane of the pipe is consistent with the orientation of the pressing plate when the pipe is selected in orientation and moved to the bending machine device for bending.

[0042] In another embodiment of the present scheme, the sensing member, the sensing block and the clamping rotating mechanism are controlled by the same control program, so that the information transmission between the sensing member and the sensing block and the information transmission between the sensing block and the clamping rotating mechanism can be quickly executed and the stability in the continuous steps is ensured.

[0043] In a preferred embodiment of the present scheme, the sensing member 5 is an optical fiber sensor and the sensing block 6 is a contact sensor, so that when the pressing plate is rotated to the optical fiber sensing position along with the pipe, the position of the pressing plate can be roughly determined by the optical fiber sensor to avoid interference between the contact sensor and the pressing plate. Meanwhile, the orientation of the pressing plate is accurately controlled by the way that the pressing plate contacts the contact sensor and stops the clamping rotating mechanism after the contact sensor approaches the pipe and stops.

[0044] It is worth mentioning that a limiting air claw is arranged at the position of the end of the pipe close to the pressing plate. When the end of the pipe is clamped and fixed by the air claw 12 and the other end abuts against the positioning block, the limiting air claw is closed to clamp and limit the position of the end of the pipe close to the pressing plate, so as to avoid the end of the pipe close to the pressing plate from falling down due to gravity, thereby avoiding the situation that the end of the pipe close to the pressing plate cannot abut against the positioning block.

[0045] Preferably, the clamping rotating mechanism 1 comprises a rotating support seat 11 and an air claw 12 rotatably arranged on the rotating support seat 11. When the pipe 2 is fixed at the clamping rotating mechanism 1, the air claw 12 clamps the end of the pipe 2 away from the pressing plate 3.

[0046] Specifically, when the pipe is clamped and fixed by the clamping rotating mechanism, the end of the pipe away from the pressing plate is clamped and fixed by the air claw. Since the end of the pipe close to the pressing plate abuts against the positioning block, the two ends of the pipe are fixed by the air claw and the positioning block respectively, so as to increase the stability of the two ends of the pipe. When the pipe is fixed by the air claw, the air claw is driven to rotate relative to the rotating support seat, so that the air claw drives the pipe to rotate circumferentially, thereby achieving the purpose that the pipe drives the pressing plate to rotate in orientation.

[0047] In an embodiment of the present scheme, the structure of the air claw adopts an existing air claw structure, which will not be described here.

[0048] Preferably, a rotating shaft 13 is arranged through the rotating support base 11, and one end of the rotating shaft 13 is connected with the air claw 12.

[0049] Specifically, the rotating shaft rotates relative to the rotating support base, thereby driving the air claw to rotate relative to the rotating support base. Since the air claw is connected with the rotating support base through the rotating shaft, the air claw can be kept stable in the axial direction during rotation through the rotating shaft, thereby increasing the stability of the pipe fitting during rotation.

[0050] In an embodiment of the present scheme, a rolling bearing is connected between the outer periphery of the rotating shaft and the rotating support base, so as to reduce the friction during rotation of the rotating shaft relative to the rotating support base.

[0051] Preferably, the clamping and rotating mechanism 1 further comprises a driving member 14, and an output end of the driving member 14 is connected with the rotating shaft 13 through a shaft coupling 15.

[0052] Specifically, the driving member is started, and the rotating shaft is driven to rotate through the shaft coupling. The rotation speed of the rotating shaft is controlled through the rotation speed output by the driving member, thereby accurately controlling the rotation speed of the pipe fitting and the pressing plate, and facilitating the stability of the orientation of the pressing plate.

[0053] In an embodiment of the present scheme, the driving member is a speed-reducing motor.

[0054] Preferably, the rotating support base 11 is fixed on an adjusting base 16, and the adjusting base 16 is movably connected with an adjusting track 17.

[0055] Specifically, when one end of the pipe fitting is clamped and fixed by the air claw, and the other end abuts against the positioning block, since the lengths of the pipe fittings are different, the rotating support base and the air claw are driven to adjust the position through the movement of the adjusting base along the adjusting track, so as to adapt to pipe fittings of different lengths.

[0056] In an embodiment of the present scheme, the position of the adjusting base after adjustment is fixed through buckle locking, jaw locking, electric driving, etc., so as to avoid the situation that the pipe fitting cannot abut against the positioning block during rotation.

[0057] Preferably, the pipe fitting 2 has a bracket 7 on the lower side, so that when the length of the pipe fitting is relatively long, the lower side of the pipe fitting can be supported by the bracket, thereby avoiding the influence of the downward falling of the distal end of the pipe fitting on the orientation of the pressing plate.

[0058] Preferably, the bracket 7 is movably arranged on a bottom track, so that when pipe fittings of different lengths are supported, the bracket can be moved relative to the bottom track, thereby increasing the stability of the pipe fitting during support by the bracket.

[0059] The present application is not limited to the above best mode, anyone under the inspiration of the present application can derive other various forms of products, but regardless of any changes in its shape or structure, as long as it has the same or similar technical solutions as this application, it falls within the scope of the present application.
