Description

Technical Field

[0001] This invention belongs to the field of hydraulic support column assembly technology, and particularly relates to an automatic fitting and tightening integrated machine. Background Technology

[0002] The current process for assembling hydraulic support columns involves fixing the outer cylinder, inserting the middle cylinder into the outer cylinder, inserting the piston into the middle cylinder, and finally assembling and tightening the two guide sleeves. There are two main types of equipment available for column assembly: horizontal and vertical.

[0003] As the volume and weight of the columns gradually increase, horizontal column assembly equipment will encounter quality problems. When using horizontal column assembly equipment, the middle cylinder is installed into the outer cylinder in a horizontal position, and the piston is pushed into the middle cylinder. The front ends of the middle cylinder and the piston will sag, which may cause the sealing ring to be sheared off during the pushing process, resulting in potential quality problems. Therefore, it is not suitable for heavy-load columns. Vertical column assembly equipment is generally operated manually. The middle cylinder is lifted by a crane and placed into the outer cylinder. Then the piston is lifted and placed into the middle cylinder. This assembly method is labor-intensive and reduces labor efficiency and productivity.

[0004] Some equipment first performs vertical assembly and flipping before horizontal transport, then flips back to vertical assembly and tightens the guide sleeve. During horizontal transport, without the fixed support of the guide sleeve, the gaps between the outer cylinder, middle cylinder, and piston are not fixed. Due to gravity, the middle cylinder and piston may tilt downwards, potentially damaging the sealing rings and hindering the guide sleeve assembly in the next process. Furthermore, lifting the piston and middle cylinder requires two different types of clamps, making changeover troublesome. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides an automatic fitting and tightening integrated machine, which integrates flipping, clamping, lifting, moving and integrated fixture tightening functions to realize continuous automated operation of column fitting and guide sleeve tightening. It has the advantages of universal fixture, efficient process and dual-mode adaptability, and solves the problems of poor equipment adaptability, easy damage to seals, high labor intensity and complicated fixture change in the prior art.

[0006] This invention is implemented as follows: an automatic fitting and tightening integrated machine includes a machine frame, on which are mounted a flipping device, an outer cylinder clamping device, a lifting support device, a column socket moving device, and a clamping moving device. The flipping device is used to rotate the workpiece 90° between horizontal and vertical states. The outer cylinder clamping device is used to clamp the column workpiece. The lifting support device is used to adjust the support height to adapt to different workpieces. The column socket moving device is used to move and position the workpiece and prevent rotation. A clamping tightening assembly is connected to the clamping moving device. The clamping tightening assembly is used to clamp the movable column and tighten the guide sleeve, realizing the integrated operation of column fitting and guide sleeve tightening without the need to change clamps.

[0007] As a preferred embodiment of the present invention, the flipping device includes a gantry frame, a variable frequency motor, a rotary table, a first gear, a first rotary support, and a support connecting plate. The variable frequency motor is used to drive the first gear, which meshes with the first rotary support to drive the rotary table to rotate, thereby realizing the flipping of the tooling between horizontal and vertical states.

[0008] This setting enables the tooling to be rotated smoothly, avoiding impact damage to the workpiece during the rotation process. It also supports horizontal / vertical dual-mode assembly to adapt to the assembly needs of columns of different sizes.

[0009] As a preferred embodiment of the present invention, the frame includes a connecting frame, a main body, a rack, a small guide rail, and a large guide rail, which serve as the basic load-bearing structure for the equipment and provide a stable installation reference and motion guidance for each device.

[0010] This design ensures the overall rigidity of the equipment through a high-strength frame structure, while the rack and pinion mechanism works in conjunction with the guide rail to achieve high-precision movement of each device, thereby improving the equipment's operational stability and positioning accuracy.

[0011] As a preferred embodiment of the present invention, the outer cylinder clamping device includes a clamping base, a first servo motor, a first coupling, a motor connecting seat, a positive and negative lead screw nut, a first guide rail slider, grippers, and a lifting quick-change block. The first servo motor drives the positive and negative lead screw nut through the first coupling, causing the grippers to open and close along the first guide rail slider to clamp the column workpiece. The lifting quick-change block can be replaced to adapt to the support requirements of different columns.

[0012] With this setup, the positive and negative screw drives the grippers to achieve symmetrical clamping, resulting in uniform and stable clamping force; the quick-change lifting block can be quickly replaced to adapt to the support surfaces of columns of different specifications, reducing changeover time and improving the equipment's versatility.

[0013] As a preferred embodiment of the present invention, the lifting support device includes a frame body, a second servo cylinder, a roller frame, a second guide rail slider, a third servo motor, a first reducer, a mounting plate, a second gear, and a V-block. The second servo motor drives the frame body to rise and fall along the second guide rail slider, and the third servo motor drives the second gear via the first reducer to drive the V-block to adjust the support height.

[0014] This setup enables precise adjustment of the support height using a dual-drive system. The V-block adapts to column workpieces of different pipe diameters, enhancing support stability and workpiece protection capabilities.

[0015] As a preferred embodiment of the present invention, the column socket moving device includes a column socket support frame, a fourth servo motor, a second reducer, a second coupling, a first mounting base, a first bearing seat, a lead screw and nut, a fixed base, a spring assembly, an outer cylinder anti-rotation mechanism, and a middle cylinder anti-rotation mechanism. The fourth servo motor drives the lead screw and nut via the second reducer and the second coupling, thereby moving the column socket support frame. The spring assembly is an elastic detection structure used to detect the column's fixed position. When the column contacts the spring assembly and is compressed to a preset stroke, it is determined that the column is fixed in place. The outer cylinder anti-rotation mechanism and the middle cylinder anti-rotation mechanism are used to prevent the workpiece from rotating when the guide sleeve is tightened.

[0016] This setup enables the lead screw drive to achieve precise positioning of the socket, the spring assembly to automatically detect the workpiece's position, and the anti-rotation mechanism to prevent the workpiece from rotating when tightening the guide sleeve, thus improving assembly accuracy and reliability.

[0017] As a preferred embodiment of the present invention, the clamping and moving device includes a clamping tightening assembly, a fifth servo motor, a third reducer, a third coupling, a second mounting base, a second bearing seat, a lead screw and nut, a third bearing seat, and a first fixed base. The fifth servo motor drives the lead screw and nut to rotate via the third reducer and the third coupling, thereby causing the clamping tightening assembly to move along the guide rail.

[0018] This setup enables the high-precision ball screw to drive the clamping and tightening components to move smoothly, ensuring the coaxiality of the fitting and tightening actions and improving assembly quality and consistency.

[0019] As a preferred embodiment of the present invention, the clamp tightening assembly includes a tightening servo motor, a tightening reducer, a third gear, a second rotary support, a clamp servo motor, a clamp reducer, a third lead screw and nut, a third guide rail slider, a guide sleeve clamp, a piston clamp, a fourth bearing seat, a telescopic part, a spring bolt, a fixing part, and a slider body.

[0020] This setup integrates clamping and tightening functions, features a compact structure, reduces equipment space requirements, and its modular design facilitates maintenance and replacement.

[0021] In a preferred embodiment of the present invention, the tightening servo motor drives the guide sleeve clamp to tighten the guide sleeve via a tightening reducer and a gear three-drive second rotary support. The clamp servo motor drives the piston clamp via a clamp reducer and a lead screw and nut three-drive piston clamp to clamp the piston. The piston clamp and the guide sleeve clamp share a set of clamp structures. The piston clamp and the guide sleeve clamp are arranged in a 90° direction, so that the piston clamping and guide sleeve tightening actions can be completed without changing the clamps.

[0022] With this setup, a single fixture can perform both piston clamping and guide sleeve tightening without the need for model change, reducing changeover time and fixture costs. The 90° arrangement of the fixture structure further improves space utilization and operational efficiency.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] Improve the versatility of fixtures: One set of fixtures can be used for both piston clamping and guide sleeve tightening, reducing the number of fixtures and the frequency of replacement, thereby reducing replacement time and cost;

[0025] Optimize the assembly process: The traditional process of fitting on both sides and tightening twice is optimized into a continuous process of fitting-tightening-fitting-tightening, which avoids damage to the sealing ring by the misalignment of the middle cylinder and piston during transportation and effectively improves the assembly quality.

[0026] Flexible adaptation to multiple scenarios: Supports horizontal / vertical dual-mode assembly, which can be adapted to both vertical assembly of large-size heavy-duty columns and horizontal assembly of small-size columns. It can be adapted to the tightening of cylinder sleeve in piston column, and can also be adapted to the tightening of cylinder sleeve assembly body and outer cylinder sleeve in piston column, with strong equipment compatibility.

[0027] High degree of automation: The entire process of feeding, fitting, tightening and flipping is completed automatically, which greatly reduces the intensity of manual labor and improves assembly efficiency and production stability. Attached Figure Description

[0039] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0040] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0041] refer to Figures 1 to 10 As shown in the figure, an automatic fitting and tightening integrated machine provided by an embodiment of the present invention includes a machine frame 2. The machine frame 2 is equipped with a flipping device 1, an outer cylinder clamping device 3, a lifting support device 4, a column socket moving device 5, and a clamping moving device 6. The flipping device 1 is used to drive the workpiece to flip 90° between a horizontal and a vertical state. The outer cylinder clamping device 3 is used to clamp the column workpiece. The lifting support device 4 is used to adjust the support height to adapt to different workpieces. The column socket moving device 5 is used to move and position the workpiece and prevent rotation. The clamping moving device 6 is connected to a clamp tightening assembly 6-1. The clamp tightening assembly 6-1 is used to clamp the movable column and tighten the guide sleeve, realizing the integrated operation of column fitting and guide sleeve tightening without the need to change the clamp.

[0042] Specifically, the flipping device 1 includes a gantry frame 1-1, a variable frequency motor 1-2, a rotary table 1-3, a gear 1-4, a first rotary support 1-5, and a support connecting plate 1-6. The variable frequency motor 1-2 drives the gear 1-4, which meshes with the first rotary support 1-5 to drive the rotary table 1-3 to rotate, thereby realizing the flipping of the tooling between horizontal and vertical states.

[0043] The above solution enables the tooling to be rotated smoothly, avoiding impact damage to the workpiece during the rotation process. It also supports horizontal / vertical dual-mode assembly, adapting to the assembly needs of columns of different sizes.

[0044] Specifically, the machine frame 2 includes a connecting frame 2-1, a machine body 2-2, a rack 2-3, a small guide rail 2-4, and a large guide rail 2-5, which serve as the basic load-bearing structure for the equipment and provide a stable installation reference and motion guidance for each device.

[0045] The above scheme ensures the overall rigidity of the equipment through a high-strength frame structure, and the rack 2-3 works in conjunction with the guide rail to achieve high-precision movement of each device, thereby improving the stability and positioning accuracy of the equipment.

[0046] Specifically, the outer cylinder clamping device 3 includes a clamping base 3-1, a first servo motor 3-2, a first coupling 3-3, a motor connecting seat 3-4, a positive and negative lead screw nut 3-5, a first guide rail slider 3-6, a gripper 3-7, and a lifting quick-change block 3-8. The first servo motor 3-2 drives the positive and negative lead screw nut 3-5 through the first coupling 3-3, which in turn drives the gripper 3-7 to open and close along the first guide rail slider 3-6 to clamp the column workpiece. The lifting quick-change block 3-8 can be replaced to adapt to the support requirements of different columns.

[0047] Using the above scheme, the positive and negative screw drives the gripper 3-7 to achieve symmetrical clamping, and the clamping force is uniform and stable; the lifting quick-change block 3-8 can be quickly replaced to adapt to the support surface of different specifications of columns, reduce changeover time, and improve the versatility of the equipment.

[0048] Specifically, the lifting support device 4 includes a frame body 4-1, a second servo cylinder 4-2, a roller frame 4-3, a second guide rail slider 4-4, a third servo motor 4-5, a first reducer 4-6, a mounting plate 4-7, a second gear 4-8, and a V-block 4-9. The second servo motor drives the frame body 4-1 to rise and fall along the second guide rail slider 4-4. The third servo motor 4-5 drives the gear 4-8 via the first reducer 4-6 to drive the V-block 4-9 to adjust the support height.

[0049] Using the above solution, the dual-drive system enables precise adjustment of the support height, and the V-blocks 4-9 are adapted to column workpieces of different pipe diameters, improving support stability and workpiece protection capabilities.

[0050] Specifically, the column socket moving device 5 includes a column socket support frame 5-1, a fourth servo motor 5-2, a second reducer 5-3, a second coupling 5-4, a first mounting base 5-5, a first bearing seat 5-6, a lead screw and nut 5-7, a fixed base 5-8, a spring assembly 5-9, an outer cylinder anti-rotation mechanism 5-10, and a middle cylinder anti-rotation mechanism 5-11. The fourth servo motor 5-2 drives the lead screw and nut 5-7 via the second reducer 5-3 and the second coupling 5-4, thereby moving the column socket support frame 5-1. The spring assembly 5-9 is an elastic detection structure used to detect the column's fixed position. When the column contacts the spring assembly 5-9 and is compressed to a preset stroke, it is determined that the column is fixed in place. The outer cylinder anti-rotation mechanism 5-10 and the middle cylinder anti-rotation mechanism 5-11 are used to prevent the workpiece from rotating when the guide sleeve is tightened.

[0051] Using the above scheme, the lead screw drive achieves precise positioning of the socket, the spring assembly 5-9 automatically detects the workpiece's position, and the anti-rotation mechanism prevents the workpiece from rotating when tightening the guide sleeve, thus improving assembly accuracy and reliability.

[0052] Specifically, the clamping and moving device 6 includes a clamping tightening assembly 6-1, a fifth servo motor 6-2, a third reducer 6-3, a third coupling 6-4, a second mounting base 6-5, a second bearing seat 6-6, a lead screw and nut 6-7, a third bearing seat 6-8, and a first fixed base 6-95-8. The fifth servo motor 6-2 drives the lead screw and nut 6-7 to rotate via the third reducer 6-3 and the third coupling 6-4, which in turn drives the clamping tightening assembly 6-1 to move along the guide rail.

[0053] Using the above solution, the high-precision ball screw drives the clamping and tightening assembly 6-1 to move smoothly, ensuring the coaxiality of the fitting and tightening actions, and improving the assembly quality and consistency.

[0054] Specifically, the clamp tightening assembly 6-1 includes a tightening servo motor 6-101, a tightening reducer 6-102, a gear 6-103, a second slewing support 6-104, a clamp servo motor 6-105, a clamp reducer 6-106, a lead screw and nut 6-107, a third guide rail slider 6-108, a guide sleeve clamp 6-109, a piston clamp 6-110, a fourth bearing seat 6-111, a telescopic part 6-112, a spring bolt 6-113, a fixing part 6-114, and a slider body 6-115.

[0055] The above solution integrates clamping and tightening functions, has a compact structure, reduces the space occupied by the equipment, and the modular design of each component facilitates maintenance and replacement.

[0056] Specifically, the tightening servo motor 6-101 drives the second rotary support 6-104 via the tightening reducer 6-102 and gear 3 6-103 to drive the guide sleeve clamp 6-109 to tighten the guide sleeve. The clamp servo motor 6-105 drives the piston clamp 6-110 to clamp the piston via the clamp reducer 6-106 and lead screw nut 3 6-107. The piston clamp 6-110 and the guide sleeve clamp 6-109 share a set of clamp structure. The piston clamp 6-110 and the guide sleeve clamp 6-109 are arranged in a 90° direction, so the piston clamping and guide sleeve tightening actions can be completed without changing the clamp.

[0057] Using the above solution, a single fixture can achieve both piston clamping and guide sleeve tightening functions without the need for model change, reducing changeover time and fixture costs. The 90° arrangement of the fixture structure further improves space utilization and work efficiency.

[0058] Working principle of the invention:

[0059] During use, vertical assembly: Pre-adjustment = The lifting support device 4 automatically raises and lowers to the preset height according to different types of columns; Middle cylinder loading and clamping = The truss automatically transports the middle cylinder to the equipment, the outer cylinder clamping device 3 clamps the middle cylinder, and the lifting quick-change block 3-8 supports the middle cylinder to a stable state; Live column loading and clamping = The truss automatically transports the live column to the equipment, and the live column clamp 6-110 automatically clamps the live column; Flipping and fitting = The flipping device 1 drives the tooling to flip 90° to a vertical state, and the clamping moving device 6 moves down to put the live column into the middle cylinder to complete the fitting; Small guide sleeve tightening = After the small guide sleeve is loaded, the clamping moving device 6 moves down, and the guide sleeve clamp 6-109 identifies and tightens the small guide sleeve to the assembly. Position; Horizontal reset = Tilting device 1 rotates 90° to a horizontal position, and the truss transfers the "live column, middle cylinder, and small guide sleeve" assembly to another machine; Outer cylinder loading and clamping = The outer cylinder clamping device 3 of the other machine clamps the outer cylinder to the appropriate height; Assembly fitting = The truss transfers the assembly to this machine, the tilting device 1 rotates 90° to a vertical position, and the clamping moving device 6 moves down to load the assembly into the outer cylinder to complete the fitting; Large guide sleeve tightening = After the large guide sleeve is loaded, the clamping moving device 6 moves down to automatically identify the large guide sleeve and tighten it into place; Assembly completion reset = Tilting device 1 rotates 90° to a horizontal position, the truss transfers the finished column, and the machine waits for the next batch of assembly;

[0060] Horizontal assembly: For small-sized columns, the equipment can maintain a horizontal state to complete the assembly. The outer cylinder clamping device 3 clamps the outer cylinder, the clamping moving device 6 horizontally pushes the middle cylinder and the piston column, and the guide sleeve clamp 6-109 horizontally tightens the guide sleeve. No flipping action is required, which further improves the assembly efficiency of small batches of small-sized columns.
