Description

Technical Field

[0001] The present invention relates to the technical field of round tube processing, in particular to an adjustable multi-bearing round tube fixed rotary cutting and welding device and a use method thereof. Background Art

[0002] In today's construction engineering, petrochemical, and mechanical processing industries, round pipes are a common processing object, and their processing quality and efficiency directly affect product performance and production progress.

[0003] Existing round tube processing devices often utilize a fixed clamping structure. As processing requirements diversify, the diameter and working height of the round tube may vary. However, the fixed height of existing processing devices makes it difficult to adapt to the needs of round tubes of varying diameters or working heights. Furthermore, the round tube must remain in a stable position during the cutting or welding process to ensure processing accuracy. However, existing fixed clamping structures are prone to deflection when subjected to high cutting or welding forces, resulting in uneven processing surfaces and even scrap. Therefore, we propose an adjustable multi-bearing fixed rotary cutting / welding device for round tubes. Summary of the Invention

[0004] In view of the above problems existing in the prior art, the purpose of the present invention is to provide an adjustable multi-bearing remote fixed rotary cutting and welding device.

[0005] Another object of the present invention is to provide an adjustable multi-bearing round tube fixed rotation cutting and welding method.

[0006] To solve the above problems, the present invention adopts the following technical solution: an adjustable multi-bearing round tube fixed rotary cutting and welding device, comprising a base, a fixed column and a laser locator, the fixed column is fixedly installed on the base, the outer edge of the fixed column is movably sleeved with a guide column, the side of the guide column facing the laser locator is fixedly connected with a connecting rod, the connecting rod is rotatably connected to the telescopic threaded rod, a fixed plate is fixedly installed at the bottom of the telescopic threaded rod, inclined plates are welded on both sides of the bottom of the fixed plate, and upper rolling bearings are arranged on both sides of the surface of the inclined plate; a tripod is fixedly installed on the base, and a lower rolling bearing is rotatably installed on the upper surface of the tripod, and the upper rolling bearing corresponds to the lower rolling bearing in vertical position.

[0007] The guide column is rotatably connected to the adjusting bolt, and the guide column is connected to the connecting rod through the adjusting bolt, and the fastening bolt is welded on the connecting rod.

[0008] The laser locator is fixedly mounted on the base and is positioned opposite to the fixing column.

[0009] A stepper motor is installed on the base, the stepper motor is fixedly connected to the rotating rod, the rotating rod is sleeved with a coupling, and the stepper motor drives the lower rolling bearing to rotate through the rotating rod and the coupling.

[0010] The connection position between the fixed plate and the telescopic threaded rod is movably connected with a nut, and the upper rolling bearing is rotated and adjusted at the bottom of the telescopic threaded rod through the nut, the inclined plate and the fixed plate.

[0011] The diameter of the guide column is larger than the diameter of the fixed column, and the guide column is driven to rise and fall on the surface of the fixed column by adjusting the bolt.

[0012] The rotating rod and the coupling are arranged between two lower rolling bearings. The stepping motor drives the rotating rod and the coupling to rotate, thereby driving the two lower rolling bearings in contact with the coupling to rotate accordingly.

[0013] The upper rolling bearing is raised and lowered and adjusted at the bottom of the connecting rod through a telescopic threaded rod, and the surfaces of the upper rolling bearing and the lower rolling bearing are covered with a rubber layer.

[0014] The present application also provides an application method for realizing the adjustable multi-bearing round tube fixed rotary cutting and welding device. When a round tube needs to be processed, the following steps are performed:

[0015] Step 1: Place the round tube on the lower rolling bearing; rotate the adjusting bolt connected to one side of the guide column surface, and the adjusting bolt interacts with the fixed column to drive the guide column to move up and down on the surface of the fixed column; rotate the telescopic threaded rod connected to the surface of the connecting rod, and rotate the telescopic threaded rod to drive the fixed plate to move up and down accordingly; the upper rolling bearing on the inclined plate below the fixed plate adjusts its height as the fixed plate rises and falls to meet the clamping height requirements of round tubes of different diameters, so that the upper and lower rolling bearings can jointly clamp the round tube stably;

[0016] Step 2: After the round tube is clamped, turn on the laser locator. The laser beam accurately points out the position of the round tube that needs to be cut or welded. The operator fine-tunes the position of the round tube according to the light spot projected by the laser locator to ensure the cutting or welding position is accurate.

[0017] Step 3: The stepper motor drives the rotating rod and the coupling to rotate. The lower rolling bearing rotates driven by the rotating rod and the coupling. Since the round tube is placed on the lower rolling bearing and is stably clamped by the upper rolling bearing, the rotation of the lower rolling bearing drives the round tube to rotate synchronously. The operator can use external cutting or welding equipment to cut or weld the rotating round tube.

[0018] Compared with the prior art, the beneficial technical effects of the present invention are:

[0019] 1. This application precisely adjusts the height of the upper rolling bearing by adjusting the guide column on the surface of the fixed column and controlling the adjusting bolt to accommodate the fixing requirements of round tubes of different diameters. Furthermore, the use of a laser locator allows for precise positioning of cutting and welding positions, greatly improving processing accuracy and ensuring consistent product quality.

[0020] 2. This application provides stable support and rotation conditions for the round tube through the combined action of the lower and upper rolling bearings. The use of the rubber layer not only improves the clamping stability but also protects the surface quality of the round tube, avoiding scratches or other damage to the surface of the round tube during processing.

[0021] 3. The stepper motor provided in this application drives the rotating rod and the coupling to rotate above the center position of the lower rolling bearing, which can realize the smooth rotation of the round tube, ensure the uniformity of the circular trajectory during cutting and welding, effectively avoid problems such as uneven welds and rough cutting surfaces, and improve the processing quality of the product.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention will be further described in detail below with reference to the embodiments and drawings.

[0028] Example

[0029] See also Figures 1 to 4The present invention provides an adjustable multi-bearing round tube fixed rotary cutting and welding device, comprising a base 100, a fixed column 103 and a laser locator 200. The fixed column 103 is fixedly installed on the left side above the base 100. Tripods 101 are fixedly installed on both sides of the center position of the base 100 surface. A lower rolling bearing 102 is rotatably installed on the upper surface of the tripod 101. A guide column 104 is movably sleeved on the surface of the fixed column 103. The diameter of the guide column 104 is larger than the diameter of the fixed column 103, and the guide column 104 is driven to rise and fall on the surface of the fixed column 103 by adjusting the bolt 105. A connecting rod 102 is fixedly connected to one side of the surface of the guide column 104. Rod 106, the surface of the connecting rod 106 is rotatably connected with a telescopic threaded rod 107, the upper rolling bearing 111 is raised and lowered and adjusted at the bottom of the connecting rod 106 through the telescopic threaded rod 107, and the surfaces of the upper rolling bearing 111 and the lower rolling bearing 102 are covered with a rubber layer, a fixed plate 109 is fixedly installed at the bottom of the telescopic threaded rod 107, and a nut is movably connected at the connection position of the fixed plate 109 and the telescopic threaded rod 107, the upper rolling bearing 111 is rotatably adjusted at the bottom of the telescopic threaded rod 107 through the nut, the inclined plate 110 and the fixed plate 109, inclined plates 110 are welded on both sides of the bottom of the fixed plate 109, and upper rolling bearings 111 are arranged on both sides of the surface of the inclined plate 110.

[0030] An adjusting bolt 105 is rotatably connected to one side of the surface of the guide column 104 , and a fastening bolt 108 is welded to the surface of the connecting rod 106 .

[0031] The laser locator 200 is fixedly installed at the rear right side of the surface of the base 100, and a stepper motor 201 is fixedly installed at the center front end of the surface of the base 100. A rotating rod 202 is fixedly connected to one side of the surface of the stepper motor 201, and a coupling 203 is fixedly sleeved on one side of the surface of the rotating rod 202. The rotating rod 202 and the coupling 203 are distributed at the center position of the lower rolling bearing 102, and the rotating rod 202 and the coupling 203 are rotated above the center position of the lower rolling bearing 102 through the stepper motor 201.

[0032] During use, when processing a circular tube, the device is first adjusted according to the diameter of the tube. Since the guide post 104 is flexibly sleeved onto the surface of the fixed post 103, and its diameter is larger than that of the fixed post 103, by rotating the adjustment bolt 105, which is connected to the guide post 104, the adjustment bolt 105 interacts with the fixed post 103, thereby driving the guide post 104 to move up and down relative to the fixed post 103. The elevation of the guide post 104 changes the height of the connecting rod 106 fixed to it.

[0033] At the same time, the telescopic threaded rod 107, which is rotatably connected to the surface of the connecting rod 106, can be rotated to raise or lower the fixed plate 109 on the telescopic threaded rod 107 using the nut at the connection between the telescopic threaded rod 107 and the fixed plate 109. Upper rolling bearings 111 are installed on the inclined plates 110 welded on both sides of the bottom of the fixed plate 109. The upper rolling bearings 111 adjust their height as the fixed plate 109 is raised or lowered, thereby adapting to the clamping height requirements of round tubes of different diameters.

[0034] After placing the tube on the lower rolling bearing 102, the height of the upper rolling bearing 111 can be fine-tuned to ensure that the upper and lower rolling bearings 111 and 102 together hold the tube stably. Furthermore, the rubber coating on the surfaces of the upper and lower rolling bearings 111 and 102 increases friction with the tube, preventing it from slipping during clamping and further improving clamping stability.

[0035] After the tube is clamped, the laser locator 200 is activated. Fixedly mounted on the right side of the base 100, it emits a laser beam that precisely indicates the location on the tube where cutting or welding is required. The operator uses the beam spot projected by the laser locator 200 to make final fine adjustments to the tube's position, ensuring the accuracy of the cutting or welding position and providing a precise positioning foundation for subsequent processing operations.

[0036] Start the stepper motor 201, which is fixedly mounted at the front center of the base 100. When the stepper motor 201 is operating, it drives the rotating rod 202, which is fixedly connected to one side of the motor, to rotate. Because the rotating rod 202 is fixedly sleeved with a coupling 203, and the rotating rod 202 and coupling 203 are located at the center of the lower rolling bearing 102, the rotating rod 202 and coupling 203 can rotate stably above the center of the lower rolling bearing 102, supported and guided by the lower rolling bearing 102.

[0037] Driven by the rotating rod 202 and coupling 203, lower rolling bearing 102 begins to rotate. Because the tube rests on lower rolling bearing 102 and is stably held by upper rolling bearing 111, the rotation of lower rolling bearing 102 drives the tube's synchronous rotation. At this point, the operator can use external cutting or welding equipment to cut or weld the rotating tube. Throughout the entire process, the tube's stable rotation ensures a uniform cutting or welding path, guaranteeing a smooth cut surface and flat weld seam.

[0038] After adjusting the clamping position of the upper rolling bearing 111 and the lower rolling bearing 102 on the round tube, the relative position of the telescopic threaded rod 107 and the connecting rod 106 can be fixed by tightening the fastening bolts 108 welded on the surface of the connecting rod 106 to prevent the position of the upper rolling bearing 111 from changing due to vibration and other reasons during the processing, thereby ensuring the stability of the round tube during the processing.
