Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioner parts processing, and particularly relates to an air conditioner pipe pressing plate direction selection device. BACKGROUND

[0002] In the processing of air conditioner pipes, a pressing plate is usually fixed to one end of an 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 in the same batch have the same 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 manual feeding and discharging cannot be realized. SUMMARY

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

[0005] To solve the above technical problems, the present application provides an air conditioner pipe pressing plate direction selection device, which comprises a clamping and rotating mechanism for driving the pipe to rotate in the circumferential direction, a positioning block abutting against one end of the pipe with a pressing plate, and an inductor and an inductive block arranged on both sides of the pipe in the circumferential direction. When the pipe is placed in the clamping and rotating mechanism and the end with the pressing plate abuts against the positioning block, the distance between the inductive 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 inductive block approaches the pipe, so that the pressing plate contacts the inductive block during rotation.

[0006] Further, the pipe has a bracket on the lower side.

[0007] Further, the bracket is movably arranged on the bottom rail.

[0008] Further, the inductor is a fiber inductor.

[0009] Further, the inductive block is a contact inductor.

[0010] Further, the clamping and rotating mechanism comprises a fixed seat, a first air claw and a second air claw movably arranged on the fixed seat, a driving wheel rotatably arranged on the first air claw, and at least two driven wheels rotatably arranged on the second air claw. When the pipe is placed in the clamping and rotating mechanism, the pipe is clamped and fixed by the driving wheel and the at least two driven wheels. When the driving wheel rotates and drives the pipe to rotate in the circumferential direction, the driven wheels rotate relative to the second air claw.

[0011] Further, the clamping and rotating mechanism further comprises a driving member, an output end of the driving member is connected with the synchronous pulley, and the synchronous pulley is connected with the driving wheel through the synchronous belt.

[0012] Further, a groove is formed on the side of the second air claw close to the first air claw, and when the pipe is placed between the driving wheel and the at least two driven wheels, the pipe is located in the groove.

[0013] The present application has the advantages of:

[0014] 1. No need to prepare a profiling block according to different pressure plates, reducing cost;

[0015] 2. The orientation position of the pressure plate is accurately positioned through the cooperation of the sensing member and the sensing block, so as to ensure the accuracy of the fixed angle between the subsequent pipe bending plane and the orientation of the pressure plate;

[0016] 3. The operation of pipe feeding, pressure plate positioning and other process steps is simple, which is beneficial to the overall processing efficiency of the air conditioner pipe. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely 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, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present application.

[0023] Those skilled in the art should understand that in the disclosure of the present application, the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the above terms cannot be understood as a limitation of the present application.

[0024] 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.

[0025] As Figures 1-4 The present application provides a kind of air conditioner pipe pressing plate direction selection device, including the clamping rotating mechanism 1 for driving pipe 2 rotation along the circumference, with the pressing plate 3 one end of pipe 2 is resisted to the positioning block 4, the inductive piece 5 and inductive block 6 are separately arranged in the circumferential two sides of pipe 2, when pipe 2 is placed in clamping rotating mechanism 1 and has the one end of pressing plate 3 and is resisted to positioning block 4, the spacing between inductive block 5 and pipe 2 is greater than the length of pressing plate 3, when pressing plate 3 rotates to the detection position of inductive piece 5, inductive block 6 is close to pipe 2, to make pressing plate 3 contact inductive block 6 in the process of rotation.

[0026] When the orientation of the pressing plate needs to be selected and positioned, the pipe with one end fixedly connected with the pressing plate is placed in the clamping rotating mechanism for clamping and fixing, and the end of the pipe with the pressing plate is resisted to the position of the positioning block, so that the positioning block limits the axial position of the pipe, thereby ensuring that the pressing plate can be detected by the inductive piece and the inductive block. Then start the clamping rotating mechanism to drive the pipe to rotate along the circumference, and make the pressing plate rotate synchronously along the circumference. In the process of rotation of the pressing plate, since the inductive piece detects it, when the pressing plate rotates to the detection position of the inductive piece, start the inductive block to move to the position of the pipe, thereby reducing the spacing between the inductive block and the pipe. When the inductive block stops moving, the spacing between the inductive block and the pipe is less than the length of the pressing plate, so that the pressing plate will contact the position of the inductive block in the process of continuing to rotate. Then the inductive block transmits a signal to control the clamping rotating mechanism to stop rotating while contacting the pressing plate, so that the pressing plate remains in the orientation just contacting the inductive block, thereby accurately realizing the orientation selection operation of the pressing plate, ensuring that the orientations of the pressing plates on each pipe are consistent, thereby increasing the consistency of the fixed angle between the orientation of the pressing plate and the bending plane of the pipe.

[0027] Wherein, by the initial placement of the pipe fittings in the clamping rotating mechanism, the distance between the induction block and the pipe fittings is greater than the length of the pressing plate, so that the pressing plate does not interfere with the induction block during the circumferential rotation of the pipe fittings, avoiding the problem of equipment jamming caused by the interference between the pressing plate and the induction block during the process of placing the pipe fittings in the clamping rotating mechanism and rotating the pressing plate. At the same time, since the induction block moves towards the pipe fittings when the induction piece detects the position of the pressing plate, and since the induction block and the induction piece are arranged on both sides of the pipe fittings, the movement of the induction block towards the pipe fittings does not interfere with the pressing plate when the induction piece detects the position of the pressing plate. Also, it ensures that the pressing plate will contact the induction block after moving closer during the process of continuing to rotate, so as to ensure the accuracy of the orientation of the pressing plate.

[0028] In particular, during the process of detecting the position of the pressing plate by the induction piece and moving the induction block towards the pipe fittings, the induction block is driven to move by devices such as air cylinders and hydraulic cylinders. When the movement of the induction block is completed, the movement is stopped and the current position is fixed by the same devices, and the specific stop position can be set in advance by the operator to adjust the orientation angle of the pressing plate.

[0029] It is worth mentioning that the orientation device used in the present scheme is suitable for pipe fittings fixedly connected with a pressing plate. The pressing plate is fixed to the pipe fittings by welding, riveting or other methods at one end of the pipe fittings to avoid the problem of inaccurate orientation caused by the movement of the pressing plate relative to the pipe fittings.

[0030] In an embodiment of the present scheme, after the orientation device provided by the present scheme determines the orientation of the pressing plate, the pipe fittings after orientation are moved to the bending machine device by moving instruments such as mechanical hands and mechanical arms. Since the angle of the pressing plate does not change during the movement of the pipe fittings by the moving instruments such as mechanical hands and mechanical arms, the bending plane of the pipe fittings and the orientation of the pressing plate are consistent when different pipe fittings pass through the orientation device and are moved to the bending machine device for bending.

[0031] In another embodiment of the present scheme, the induction piece, the induction block and the clamping rotating mechanism are controlled by the same control program to enable the information transmission between the induction piece and the induction block and the information transmission between the induction block and the clamping rotating mechanism to be executed quickly and to ensure the stability in the continuous steps.

[0032] In a preferred embodiment of the present scheme, the induction piece 5 is a fiber optic sensor and the induction block 6 is a contact sensor, so that when the pressing plate is rotated to the fiber optic sensing position along with the pipe fittings, the position of the pressing plate can be roughly determined by the fiber optic sensor to avoid the interference between the contact sensor and the pressing plate. At the same time, after the contact sensor moves close to the pipe fittings and stops, 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.

[0033] Preferably, the pipe 2 has a bracket 7 on the lower side, so that when the pipe is long, the bracket can support the lower side of the pipe, avoiding the situation that the far end of the pipe falls downward, which affects the selection direction of the pressing plate.

[0034] Preferably, the bracket 7 is movably arranged on the bottom rail, so that when pipes of different lengths are supported, the bracket can be moved relative to the bottom rail to increase the stability of the pipe during support.

[0035] Preferably, the clamping and rotating mechanism 1 comprises a fixed seat 11, a first air claw 12 and a second air claw 13 movably arranged on the fixed seat 11, a driving wheel 14 rotatably arranged on the first air claw 12, and at least two driven wheels 15 rotatably arranged on the second air claw 13. When the pipe 2 is placed in the clamping and rotating mechanism 1, the pipe 2 is clamped and fixed by the driving wheel 14 and the at least two driven wheels 15, and when the driving wheel 14 rotates and drives the pipe 2 to rotate circumferentially, the driven wheels 15 rotate relative to the second air claw 13.

[0036] Specifically, when the pipe needs to be placed in the clamping and rotating mechanism, the first air claw and the second air claw move away from each other along the fixed seat to increase the distance between the first air claw and the second air claw, so that the pipe can be placed between the first air claw and the second air claw. Then, when the pipe is placed between the first air claw and the second air claw and one end of the pressing plate is pressed against the positioning block, the first air claw and the second air claw move closer to each other along the fixed seat and clamp and fix the outer periphery of the pipe through the driving wheel and the at least two driven wheels, so as to increase the stability of the pipe. When the pipe needs to rotate circumferentially, the driving wheel is started to rotate, and then the driving wheel drives the pipe to rotate, so as to achieve the purpose of rotating the pressing plate by the pipe. At the same time, since the driven wheels also rotate synchronously relative to the second air claw, the second air claw can assist the rotation of the pipe on the basis of clamping and fixing the outer periphery of the pipe, which reduces the friction between the second air claw and the pipe and avoids the problem that the pressing plate cannot be selected due to the inability of the pipe to rotate.

[0037] In an embodiment of the present scheme, the movement of the first air claw and the second air claw relative to the fixed seat adopts an existing air claw structure.

[0038] Preferably, the clamping and rotating mechanism 1 further comprises a driving member 16, the output end of the driving member 16 is connected with a synchronous pulley 17, and the synchronous pulley 17 is connected with the driving wheel 14 through a synchronous belt 18.

[0039] Specifically, when the pipe is needed to be rotated along the circumference by the driving wheel, the driving member drives the synchronous belt wheel to rotate, and then the driving wheel is driven to rotate synchronously by the synchronous belt, so as to achieve the purpose of driving the pipe to rotate by the driving wheel. Meanwhile, the rotation speed of the pipe and the pressing plate can be adjusted by the rotation speed of the driving member. When the pressing plate contacts the induction block, the rotation of the pipe can be quickly stopped by stopping the driving member, thereby increasing the stability of the direction selection of the pressing plate.

[0040] In an embodiment of the present scheme, the driving member is a speed reduction motor.

[0041] Preferably, the second air claw 13 is provided with a groove 19 on the side close to the first air claw 12. When the pipe 2 is placed between the driving wheel 14 and the at least two driven wheels 15, the pipe 2 is located in the groove 19.

[0042] Specifically, since the pipe is clamped and fixed, the pipe is located in the groove, so that the distance between the first air claw and the second air claw is smaller, thereby reducing the overall structure size of the direction selection device, and making the overall equipment more compact.

[0043] The present application is not limited to the above-mentioned best mode, and anyone can derive other various forms of products under the inspiration of the present application, but regardless of any changes in shape or structure, any technical solution with the same or similar technical solutions as the present application falls within the protection scope of the present application.
