Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe processing, in particular to an automatic feeding equipment for inserting inner pipes into both ends of a pipe. BACKGROUND

[0002] Inserting an inner pipe into a pipe is a common pipe reinforcing method. For a pipe, the design of inserting an inner pipe can meet the needs of lightweight and reduced material cost, and can also ensure the material structural strength.

[0003] The prior art inner pipe insertion process first inserts an inner pipe into a pipe on a support through a gas cylinder, and then fixes the inner pipe by a pressing point mechanism to ensure the stability and precision requirements of the inner pipe insertion process. The pressing point mechanism forms small pits on the outer wall of the pipe, and forms convex points on the inner wall of the pipe, so as to clamp the inner pipe to avoid slipping and displacement during subsequent production.

[0004] The prior art pressing point mechanism has the following technical problems,

[0005] First, after inserting the inner pipe into the pipe, the pressing head of the pressing point mechanism vertically presses the pipe downward. In this process, the inner pipe in the pipe is easily affected by external equipment vibration and is displaced, resulting in a gap between the inner pipe and the convex point.

[0006] Second, in order to facilitate the installation of the inner pipe, the pipe hole diameter is generally greater than the inner pipe diameter, and the gap between the two will cause the inner pipe to shake in the pipe during future use of the pipe, thereby affecting the use of the pipe. SUMMARY

[0007] The present application relates to the technical field of pipe processing, in particular to an automatic feeding equipment for inserting inner pipes into both ends of a pipe.

[0008] The present application relates to the technical field of pipe processing, in particular to an automatic feeding equipment for inserting inner pipes into both ends of a pipe.

[0009] An automated feeding device for inserting inner tubes into both ends of pipe fittings includes a truss. At the bottom of the truss are mounted a feeding assembly, a hopper conveying assembly, a weld inspection assembly, a pressure point assembly, and a clamping assembly.

[0016] The beneficial effects of this invention are:

[0017] (1) The present application drives the pressing sleeve downward through the cylinder, and the rear fixed pressing head presses the pipe fitting. The motor drives the rotating guide sleeve to rotate in the fan-shaped groove. The rotating guide sleeve rotates, and the overlapping area of the rotating guide sleeve and the fixed guide sleeve gradually increases. At this time, the sliding sleeve can gradually move along the direction of the fixed guide sleeve, so that the rear fixed pressing heads on the two pressing sleeves move close to each other, the pressing concave points of the rear fixed pressing heads gradually move close to the inner tube direction, until the convex points on the inner wall of the pipe fitting are attached to the end of the inner tube, and the inner tube is corrected and axially limited by the convex points on the inner wall of the pipe fitting, avoiding the gap between the inner tube and the convex points due to the vibration of external equipment;

DETAILED DESCRIPTION

[0034] 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, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.

[0035] Please refer to Figures 1-13As shown, this invention is an automated feeding device for inserting inner tubes into both ends of pipe fittings. It includes a truss 2, with a feeding assembly 1, a hopper conveying assembly 4, a weld detection assembly 5, a pressure point assembly 6, and a clamping assembly 8 installed at the bottom of the truss 2. Inner tube insertion assemblies 7 are installed on both sides of the pressure point assembly 6. The pipe fitting enters the hopper conveying assembly 4 through the feeding assembly 1. The hopper conveying assembly 4 feeds the pipe fitting into the weld detection assembly 5, and then the clamping assembly 8 feeds the pipe fitting between the pressure point assemblies 6. The inner tube insertion assembly 7 pushes the inner tube into the pipe fitting. The pressure point assembly 6 includes two symmetrically installed pressure point frames 601. A cylinder 603 is installed on each pressure point frame 601, and the output end of the cylinder 603 is connected to a push rod 605. An adjustable outer sleeve 604 is installed on each pressure point frame 601. A sliding pressure sleeve 607 is installed inside the sleeve 607, and a push rod 605 passes through the outer sleeve 604 and connects to the pressure sleeve 607. A slanted groove 608 is opened on one side of the pressure sleeve 607, and a fixed guide sleeve 609 is installed in the slanted groove 608. A fan-shaped groove 610 is opened on the other side of the pressure sleeve 607, and a rotating guide sleeve 611 is rotatably installed in the fan-shaped groove 610. The rotating guide sleeve 611 and the fixed guide sleeve 609 are symmetrically arranged. An I-shaped slide member 615 is slidably installed inside the pressure sleeve 607. A sliding sleeve 614 is slidably installed on the I-shaped slide member 615. The shafts at both ends of the sliding sleeve 614 are respectively connected to the fixed guide sleeve 609 and the rotating guide sleeve 611. A rear fixed pressure head 616 and a front sliding pressure head 617 are installed at the bottom of the sliding sleeve 614, and the front sliding pressure head 617 is located at the front end of the rear fixed pressure head 616.

[0036] Specifically, a U-shaped frame 612 is installed on the side wall of the pressure sleeve 607, and a motor 613 is installed on the U-shaped frame 612. The output shaft of the motor 613 is connected to the end of the rotating guide sleeve 611.

[0037] Specifically, the front sliding pressure head 617 includes a slide table 6170 mounted on a slide sleeve 614, and a pressure tube head 6171 is slidably mounted inside the slide table 6170. The pressure tube head 6171 is connected to the inner wall of the slide cavity of the slide table 6170 by a spring 6172. Specifically, a pad 6173 is mounted on the pressure tube head 6171.

[0038] In the initial state, the rotating guide sleeve 611 and the fixed guide sleeve 609 are symmetrical, and the rotating guide sleeve 611 and the fixed guide sleeve 609 restrict the sliding sleeve 614 through the shafts on both sides of the sliding sleeve 614.

[0039] It should be noted that,

[0040] Inserting the inner tube: The pipe enters the hopper conveying assembly 4 through the feeding assembly 1. The hopper conveying assembly 4 sends the pipe into the weld inspection assembly 5. After the pipe is inspected, the clamp on the clamping assembly 8 clamps the pipe and sends it between the pressure point assemblies 6, so that the pipe is located between the two pressure point frames 601 and the pipe is aligned with the hole on the orifice plate 602. Then, the inner tube is pushed through the orifice plate 602 by the inner tube insertion assembly 7 and inserted into the pipe.

[0041] The pressing point operation; in order to prevent the inner tube from being displaced during the pressing point of the pipe fitting, the rear fixed pressing head 616 is pressed together with the inner tube, see Figure 12 , the spacing between the pressing sleeves 607 of the present application is greater than the length of the inner tube, thereby improving the fault tolerance of the pressing point and avoiding the rear fixed pressing head 616 being pressed together with the inner tube.

[0042] The cylinder 603 drives the pressing sleeve 607 to move downward through the push rod 605, and the rear fixed pressing head 616 and the front sliding pressing head 617 are respectively attached to the outer wall of the pipe fitting. As the pressing sleeve 607 moves downward, the rear fixed pressing head 616 exerts pressure on the pipe fitting, and at the same time, the pressing pipe head 6171 is retracted into the inner part of the sliding table 6170. As the rear fixed pressing head 616 exerts pressure on the pipe fitting, the motor 613 drives the rotating guide sleeve 611 to rotate inside the fan-shaped groove 610. By rotating the rotating guide sleeve 611, the overlapping area between the rotating guide sleeve 611 and the fixed guide sleeve 609 gradually increases. At this time, the sliding sleeve 614 can gradually move along the direction of the fixed guide sleeve 609, so that the rear fixed pressing heads 616 on the two pressing sleeves 607 move closer to each other, prompting the pressing concave points of the rear fixed pressing head 616 to gradually move in the direction of the inner tube, until the convex points on the inner wall of the pipe fitting are attached to the end of the inner tube. By tightly attaching the convex points on the inner wall of the pipe fitting to the two side end faces of the inner tube, the inner tube is corrected and axially limited, avoiding the gap between the inner tube and the convex points due to external equipment vibration.

[0043] Specifically, considering that the inner tube needs to be inserted into the pipe fitting during the operation, the inner tube needs to be inserted into the pipe fitting, and the gap between the two will cause the inner tube to shake in the pipe fitting in the future.

[0044] During the pressing point operation of the rear fixed pressing head 616, the pressing pipe head 6171 is retracted into the inner part of the sliding table 6170, and at the same time, the spring 6172 is compressed, so that the pressing pipe head 6171 is tightly attached to the outer wall of the pipe fitting. When the convex points on the inner wall of the pipe fitting are attached to the end of the inner tube, the front sliding pressing head 617 and the rear fixed pressing head 616 are in a high-low posture, and the pad 6173 on the pressing pipe head 6171 is attached to the inner wall of the sliding cavity of the sliding table 6170. The motor 613 is turned off to fix the current position of the rear fixed pressing head 616 and the front sliding pressing head 617. As the pressing sleeve 607 continues to move downward, the front sliding pressing head 617 presses the outer wall of the pipe fitting, and the convex points pressed by the front sliding pressing head 617 radially fix the inner tube, preventing the inner tube from shaking in the pipe fitting during subsequent use.

[0045] Specifically, the present application limits the downward pressure of the pressing pipe head 6171 by sliding cooperation between the pressing pipe head 6171 and the sliding table 6170, so that the front sliding pressing head 617 only presses the pipe fitting, avoiding the front sliding pressing head 617 being pressed together with the inner tube.

[0046] Referring to Figure 1The manipulator 3 is installed on the truss 2, and the manipulator 3 moves the finished pipe to a discharge table. It should be noted that the manipulator 3 automatically moves the pipe to the discharge table after the pressing point operation is completed, so that automatic feeding is realized. The manipulator 3 can also feed the inner tube assembly 7, so that automatic feeding is realized, and the production line automation is improved. The weld detection assembly 5 adopts ultrasonic detection, and the hopper conveying assembly 4 adopts a conveying belt conveying technology. The use methods and working principles of the hopper conveying assembly 4 and the weld detection assembly 5 are prior art, and the present application will not be described in detail.

[0047] Referring to Figures 3-4 The hole plate 602 is installed on the pressing point frame 601, the clamping assembly 8 moves the pipe between the hole plates 602, and the inner tube assembly 7 pushes the inner tube to pass through the hole plate 602 and insert into the pipe. It should be noted that when the inner tube assembly 7 pushes the inner tube to pass through the hole plate 602 and insert into the pipe, the hole plate 602 can guide the inner tube, so that the inner tube does not collide with the pipe due to the stroke deviation of the inner tube assembly 7.

[0048] Referring to Figure 4 The adjustment table 606 is installed on the pressing point frame 601, and the adjustment table 606 is connected with the outer sleeve 604. It should be noted that the adjustment table 606 is used to adjust the height of the outer sleeve 604, so that the pressing point operation of pipes of different specifications is realized.

[0049] The implementation principle of the present application is as follows:

[0050] In the initial state, the rotating guide sleeve 611 is symmetrical with the fixed guide sleeve 609, and the rotating guide sleeve 611 and the fixed guide sleeve 609 limit the sliding sleeve 614 through the shaft rods on both sides of the sliding sleeve 614.

[0051] The inner tube is inserted into the pipe; the pipe enters the hopper conveying assembly 4 through the feeding assembly 1, the hopper conveying assembly 4 sends the pipe into the weld detection assembly 5, after the pipe detection is completed, the pipe is clamped by the upper clamp of the clamping assembly 8 and sent to the pressing point assembly 6, so that the pipe is located between the two pressing point frames 601, and the pipe is aligned with the holes on the hole plate 602; then the inner tube is pushed to pass through the hole plate 602 and insert into the pipe through the inner tube assembly 7.

[0052] The pressing point operation is performed; in order to prevent the inner tube from being displaced during the pressing point operation of the pipe, so that the rear fixed pressing head 616 presses together with the inner tube, referring to Figure 12 The distance between the pressing sleeves 607 is greater than the length of the inner tube, so that the fault tolerance of the pressing point is improved, and the rear fixed pressing head 616 is prevented from pressing together with the inner tube.

[0053] The cylinder 603 drives the pressing sleeve 607 to move downward through the push rod 605, and the rear fixed pressing head 616 and the front sliding pressing head 617 are respectively attached to the outer wall of the pipe fitting. With the downward movement of the pressing sleeve 607, the rear fixed pressing head 616 presses the pipe fitting, and at the same time, the pressing pipe head 6171 is retracted into the inner part of the sliding table 6170. With the pressing of the rear fixed pressing head 616 on the pipe fitting, the motor 613 drives the rotating guide sleeve 611 to rotate in the fan-shaped groove 610. Through the rotation of the rotating guide sleeve 611, the overlapping area of the rotating guide sleeve 611 and the fixed guide sleeve 609 gradually increases. At this time, the sliding sleeve 614 can gradually move along the direction of the fixed guide sleeve 609, so that the rear fixed pressing heads 616 on the two pressing sleeves 607 move close to each other, prompting the pressing concave points of the rear fixed pressing head 616 to gradually move close to the direction of the inner tube, until the convex points on the inner wall of the pipe fitting are attached to the end part of the inner tube. Through the way that the convex points on the inner wall of the pipe fitting are tightly attached to the end faces of the inner tube on both sides, the inner tube is corrected and axially limited, avoiding the gap between the inner tube and the convex points due to the vibration of external equipment.

[0054] Specifically, considering that the inner tube needs to be inserted into the pipe fitting, the diameter of the pipe fitting needs to be larger than the diameter of the inner tube, and the gap between the two will cause the inner tube to shake in the pipe fitting in the future. During the pressing process of the rear fixed pressing head 616, the pressing pipe head 6171 is retracted into the inner part of the sliding table 6170, and at the same time, the spring 6172 is pressed, so that the pressing pipe head 6171 is tightly attached to the outer wall of the pipe fitting. When the convex points on the inner wall of the pipe fitting are attached to the end part of the inner tube, the front sliding pressing head 617 and the rear fixed pressing head 616 are in a high-low posture, the pad 6173 on the pressing pipe head 6171 is attached to the inner wall of the sliding cavity of the sliding table 6170, the motor 613 is turned off, and the current position of the rear fixed pressing head 616 and the front sliding pressing head 617 is fixed. With the continuous downward movement of the pressing sleeve 607, the front sliding pressing head 617 presses the outer wall of the pipe fitting, and the convex points pressed by the front sliding pressing head 617 fix the inner tube radially, preventing the inner tube from shaking in the pipe fitting in subsequent use.
