Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to an automatic tightening device for installing hexagonal pipe thread joints. Background Technology

[0002] Hexagonal pipe thread fittings are a common type of pipe connector, widely used in industrial pipeline connections. For example, they are used to connect the inlet and outlet of water pump heads to pipelines; control valves (ball valves, gate valves, etc.) to pipelines; and hydraulic cylinders to oil pipes. Hexagonal pipe thread fittings are an indispensable component for pipeline connections.

[0003] During the installation of hexagonal pipe threaded fittings, improper installation or insufficient torque can easily lead to leakage risks. Especially in vibrating environments, the fittings are more prone to loosening due to vibration after prolonged operation, creating potential hazards and increasing future maintenance costs.

[0004] However, hexagonal pipe threaded joints are usually installed using a hexagonal wrench. Manual operation makes it difficult to control torque, and different operators have difficulty ensuring that the installation force is consistent. Furthermore, with mass production, operators are prone to fatigue, which may result in insufficient tightening, causing leakage risks and hindering the improvement of product competitiveness. Utility Model Content

[0005] To address the problems in the prior art, this utility model provides an automatic tightening device for installing hexagonal pipe threaded joints, which solves the problems of manual installation of hexagonal pipe threaded joints, which is difficult to standardize and prone to leakage at the installation point.

[0006] This utility model discloses an automatic tightening device for installing hexagonal pipe threaded connectors, comprising a device mounting frame, a tightening controller, a tightening moving component, a tightening component, and a product placement seat. The tightening moving component and the tightening component are electrically connected to the tightening controller. The tightening component is fixedly mounted on the moving end of the tightening moving component, and the tightening moving component can drive the tightening component to move closer to the product placement seat. The tightening component includes a rotary drive and a hexagonal sleeve, with the hexagonal sleeve located on the moving end of the rotary drive. The rotary drive can drive the hexagonal sleeve to rotate and install the hexagonal pipe threaded connector onto the designated product.

[0007] The present invention is further improved by including a connector positioning component, which is disposed between the tightening component and the product placement seat. The connector positioning component includes an opening and closing drive component and two positioning claws. The two positioning claws are respectively disposed on both sides of the hexagonal pipe thread connector. Each of the two positioning claws is provided with a positioning part, which can restrict the placement direction of the hexagonal pipe thread connector.

[0008] This utility model is further improved by having two tightening components and two joint positioning components, with the two tightening components and the two joint positioning components working together.

[0009] This utility model is further improved by positioning part being a positioning movable groove set on positioning claw. A floating block and a positioning sensing elastic element are set in the positioning movable groove. The floating block can move up and down in the positioning movable groove in coordination with the positioning sensing elastic element.

The rotation drive can determine the rotation angle through the cooperation of the angle sensing block and the angle positioning sensor.

[0015] This utility model is further improved by providing a reset button and a device switch button on the tightening controller. The reset button can restore the tightening moving component and the tightening component to their initial positions.

[0016] Compared with the prior art, the beneficial effects of this utility model are: it can effectively solve the problems of manual installation of hexagonal pipe threaded joints, which are difficult to standardize and prone to leakage at the installation point. By setting the tightening moving component, the tightening component can be controlled to move to the designated position, so that the hexagonal sleeve is fitted on the hexagonal pipe threaded joint.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] like Figures 1-5 As shown, this utility model is an automatic tightening device for installing hexagonal pipe threaded joints. It includes a device mounting frame 1, on which a tightening controller, a tightening moving component 3, a tightening component, and a product placement seat 4 are provided. The tightening moving component 3 and the tightening component are electrically connected to the tightening controller. The tightening component is fixedly installed at the moving end of the tightening moving component 3. The tightening moving component 3 can drive the tightening component to move closer to the product placement seat 4. The tightening component includes a rotary drive 51 and a hexagonal sleeve 52. The hexagonal sleeve 52 is installed at the moving end of the rotary drive 51. The rotary drive 51 can drive the hexagonal sleeve 52 to rotate and install the hexagonal pipe threaded joint 6 on the designated product.

[0027] By setting the tightening moving component 3, the tightening component can be controlled to move to a designated position, so that the hexagonal sleeve 52 is fitted onto the hexagonal pipe threaded connector 6. The rotation drive component 51 in the tightening component controls the rotation of the hexagonal sleeve 52, thereby enabling the hexagonal pipe threaded connector 6 to complete the efficient assembly with the product, effectively unifying the installation standard, improving the level of production automation, solving the problem of leakage that easily occurs at the installation connection of the hexagonal pipe threaded connector 6, and helping to improve the competitiveness of enterprises.

[0028] The illustration of this scheme shows a hexagonal pipe threaded connector 6 installed on a water pump head 7, which includes an inlet 71 and an outlet 72.

[0029] The automatic tightening device for installing hexagonal pipe threaded joints also includes a joint positioning component 8, which is disposed between the tightening component and the product placement seat 4. The joint positioning component 8 includes an opening and closing drive component 81 and two positioning claws 82. The two positioning claws 82 are respectively disposed on both sides of the hexagonal pipe threaded joint 6, and each of the two positioning claws 82 is provided with a positioning part.

[0030] By setting the connector positioning component 8, the hexagonal pipe thread connector 6 can be pre-positioned before tightening, preventing misalignment during subsequent tightening operations due to external factors or improper installation.

[0031] Before the tightening process, the hexagonal pipe thread connector 6 is placed between the two positioning claws 82. The opening and closing drive component 81 can control the opening or closing of the two positioning claws 82.

[0032] The positioning part restricts the placement direction of the hexagonal pipe thread connector 6, ensuring high processing efficiency for the tightening process.

[0033] The positioning part is a positioning movable groove set on the positioning claw 82. A floating block 83 and a positioning sensing elastic element 84 are set in the positioning movable groove. The floating block 83 can move up and down in the positioning movable groove in coordination with the positioning sensing elastic element 84. The side of the floating block 83 is set parallel to the side of the hexagonal pipe threaded joint 6.

[0034] When placing the hexagonal pipe threaded connector 6, the floating blocks 83 of the two positioning claws 82 will position the hexagonal pipe threaded connector 6 to avoid the placement angle deviation.

[0035] The tightening moving component 3 drives the tightening component to move downwards, and the hexagonal sleeve 52 is gradually fitted onto the hexagonal pipe thread joint 6. At the same time, the floating block 83 is pressed into the positioning movable groove by the hexagonal sleeve 52. Under the action of the position sensing elastic element 84, the position signal is obtained. After determining that the movement has reached the position, the tightening process is carried out.

[0036] The positioning sensing elastic element 84 includes a first positioning sensing element and a compression spring, with the compression spring disposed below the floating block 83.

[0037] The floating block 83 is supported by a compression spring.

[0038] The tightening moving component 3 includes a sliding plate 31 and a lifting drive component 32. The lifting drive component 32 is fixedly mounted on the device mounting frame 1, and the sliding plate 31 is fixedly connected to the moving end of the lifting drive component 32.

[0039] The lifting drive component 32 enables the sliding plate 31 to move up and down.

[0040] The device mounting frame 1 is provided with multiple guide posts 101, and the sliding plate 31 is provided with guide holes that cooperate with the guide posts 101, with the guide posts 101 set in the guide holes.

[0041] The cooperation between the guide post 101 and the guide hole makes the sliding plate 31 more stable during the lifting and lowering process.

[0042] The sliding plate 31 is provided with a second positioning sensor 311, and the device mounting frame 1 is provided with a positioning sensor block that cooperates with the second positioning sensor 311. The lifting drive 32 can determine the position of movement through the cooperation of the second positioning sensor 311 and the positioning sensor block.

[0043] When both the first positioning sensor and the second positioning sensor 311 simultaneously detect a signal indicating that the device has moved into position, the tightening process can proceed.

[0044] An angle sensing block is provided on the outer surface of the hexagonal sleeve 52, and an angle positioning sensor 312 that cooperates with the angle sensing block is provided on the sliding plate 31. The rotation drive 51 can determine the rotation angle through the cooperation of the angle sensing block and the angle positioning sensor 312.

[0045] By setting the angle sensing block, an angle reference point can be provided. Before the tightening process, the rotary drive component 51 first controls the angle of the hexagonal sleeve 52 to reset, so that the rotation angle of the hexagonal sleeve 52 is consistent with the angle of the hexagonal pipe thread joint 6 restricted by the two floating blocks 83, thereby improving the processing accuracy and avoiding the situation where the tightening moving component 3 drives the hexagonal sleeve 52 to move downward, and the hexagonal sleeve 52 cannot be accurately fitted onto the hexagonal pipe thread joint 6.

[0046] The tightening controller is equipped with a reset button 21 and a device switch button 22. The reset button 21 can restore the tightening moving component 3 and the tightening component to their initial positions.

[0047] There are two tightening components and two connector positioning components 8. The two tightening components and the two connector positioning components 8 work together. By setting up two tightening components, two hexagonal pipe thread connectors 6 can be installed on the water inlet 71 and the water outlet 72 of the water pump head 7 at the same time, which effectively improves the installation efficiency.

[0048] The rotary drive component 51 is a vertical geared motor, equipped with a speed regulating connector and a voltage regulator.

[0049] The lifting drive component 32 is a lifting drive cylinder. The lifting drive cylinder is equipped with a speed regulating connector. The pushing and pulling speed of the moving end of the lifting drive cylinder can be controlled by the speed regulating connector.

[0050] The opening and closing drive component 81 is a pneumatic clamping cylinder. The pneumatic clamping cylinder is equipped with a pressure regulator, which adjusts the input air pressure as needed.

[0051] The mounting bracket 1 is provided with a guide rail 102, and the sliding plate 31 is provided with a guide groove on the side facing the guide rail 102. Through the cooperation of the guide groove and the guide rail 102, the stability of the lifting and lowering movement of the sliding plate 31 can be further improved.

[0052] Work process:

[0053] Press the reset button 21, tighten the controller to start the self-test program. The angle positioning sensor 312 detects the angle sensing block on the hexagonal sleeve 52. If it cannot detect it, the vertical geared motor slowly rotates until the angle positioning sensor 312 is aligned with the angle sensing block, and then stops rotating. This setting is to ensure that the internal hexagonal direction of the hexagonal sleeve 52 is exactly consistent with the hexagonal head direction of the hexagonal pipe thread connector 6.

[0054] Push the water pump head 7 into the product placement seat 4, and place the hexagonal pipe threaded connector 6 between the two positioning claws 82. At this time, the hexagonal pipe threaded connector 6 should be aligned with the threaded hole on the water pump head 7. When placing it, both sides of the hexagonal pipe threaded connector 6 need to be parallel to the side of the floating block 83. This ensures that the hexagonal direction of the hexagonal pipe threaded connector 6 is completely consistent with the internal hexagonal direction of the hexagonal sleeve 52.

[0055] Turn on the device switch button 22. At this time, the lifting drive cylinder pushes the sliding plate 31 and the vertical geared motor to slowly move down together. When the second positioning sensor 311 senses the positioning sensor block, the hexagonal sleeve 52 has wrapped around the hexagonal head of the hexagonal pipe threaded connector 6. The floating block 83 will be pressed down by the hexagonal sleeve 52. At this time, the tightening controller starts the working program. The pneumatic clamping cylinder drives the two positioning claws 82 to open to both sides. At the same time, the vertical geared motor starts to rotate, gradually screwing the hexagonal pipe threaded connector 6 into the threaded hole of the water pump head 7. When the vertical geared motor rotates to the specified angle and stops rotating, the hexagonal pipe threaded connector 6 is tightened. At this time, the torque borne by the hexagonal pipe threaded connector 6 is about 10 N.m, which is equal to the output torque of the vertical geared motor under the limited current.

[0056] Press the device switch button 22 again to turn off the device. The vertical geared motor is powered off, and the lifting drive cylinder pulls the sliding plate 31 and the vertical geared motor back to the initial position.

[0057] Remove the water pump head 7.

[0058] Press the reset button 21 again, and the pneumatic clamping cylinder will drive the two positioning claws 82 to close. Tighten the controller and start the self-test program again. The angle positioning sensor 312 will detect the angle sensing block on the hexagonal sleeve 52. If it cannot be detected, the vertical geared motor will slowly rotate until the angle positioning sensor 312 is aligned with the angle sensing block, and then stop rotating.

[0059] In this way, one cycle of operation is completed.

[0060] As can be seen from the above, the beneficial effects of this utility model are: it can effectively solve the problems of manual installation of hexagonal pipe thread connector 6 in the prior art, which is difficult to standardize and prone to leakage at the installation point. By setting the tightening moving component 3, the tightening component can be controlled to move to the designated position, so that the hexagonal sleeve 52 is fitted on the hexagonal pipe thread connector 6. The rotation drive component 51 in the tightening component controls the rotation of the hexagonal sleeve 52, thereby enabling the hexagonal pipe thread connector 6 to complete the efficient assembly with the product, effectively unifying the installation standard, improving the level of production automation, solving the problem of easy leakage at the installation connection of the hexagonal pipe thread connector 6, and helping to improve the competitiveness of enterprises.
