Description

Technical Field

[0001] The present invention relates to the field of mechanical manufacturing, and particularly to a small-diameter elbow groove processing tool. Background Art

[0002] According to design or process requirements, a groove with a certain geometric shape processed and assembled at the weld joint of a welded part is called a groove. The groove is mainly for welding workpieces to ensure the welding degree. Under normal circumstances, the surface formed by machining methods is used. When the requirements are not high, gas cutting can also be used (if it is a type I weld and ultrasonic flaw detection is required, only machining methods can be used), but the oxide slag needs to be removed. According to needs, there are K-type grooves, V-type grooves, U-type grooves, etc.

[0003] Currently, due to the different bending degrees of different workpieces, it is difficult to fix different workpieces with existing groove processing workpieces, and there are large limitations. Moreover, due to different workpieces, the orientations of the holes on the workpieces are also different, which is not convenient for workers to process them. Therefore, we propose a small-diameter elbow groove processing tool. Summary of the Invention

[0004] The main purpose of the present invention is to provide a small-diameter elbow groove processing tool, which can effectively solve the problems that it is difficult to fix different workpieces with different bending degrees of elbows and it is difficult to control the orientation of the workpiece holes.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] The small-diameter elbow groove processing tool includes a support table. Four fixing columns are fixedly connected to the upper end of the support table. A workbench is fixedly connected to the upper ends of the fixing columns. A gas cutting gun is placed on the left part of the upper end of the workbench. A turntable is slidably connected to the right part of the upper end of the workbench. A workpiece is placed in the middle of the upper end of the turntable. A fine-tuning device is arranged in the inner cavity of the workbench. An equipment table is fixedly connected to the left and right parts of the upper end of the turntable. A clamping device is arranged in the middle of the equipment table.

[0007] Preferably, the clamping device includes a limiting sleeve. Fixing rods are fixedly connected to both the front and rear ends of the limiting sleeve. A fixing sleeve is slidably connected to the inner cavity of the limiting sleeve. An electric telescopic rod is fixedly connected to the upper wall of the inner cavity of the fixing sleeve. A rotating rod is fixedly connected to the upper end of the fixing sleeve. A nut is threadedly connected to the lower part of the outer surface of the rotating rod. The lower end of the electric telescopic rod extends below the fixing sleeve and is fixedly connected to a limiting block.

[0008] Preferably, the limiting sleeve is located inside the equipment table. One ends of the two fixing rods far from the limiting sleeve are respectively fixedly connected to the front wall and the rear wall of the inner cavity of the equipment table. The outer surface of the fixing rod is inserted through the bottom wall of the equipment table. The rotating rod is located above the equipment table.

[0009] Preferably, two sets of clamping devices are provided, and the clamping devices are respectively located at the left and right parts of the equipment table. Both limiting blocks are arc-shaped structures, and both limiting blocks are located above the workpiece.

[0010] Preferably, the fine-tuning device includes a rotating shaft. The lower end of the rotating shaft is movably connected to the support table through a bearing. The left part of the inner cavity of the workbench is movably connected to a screw rod through a bearing. The right part of the workbench is fixedly connected to a sliding rod. A plurality of clamping grooves are formed on the outer surface of the turntable. The front end of the screw rod is fixedly connected to a handle. Two connecting plates are commonly inserted through the outer surfaces of the screw rod and the sliding rod. Opposite end faces of the two connecting plates are fixedly connected with clamping blocks.

[0011] Preferably, the two clamping blocks are respectively clamped with the clamping grooves. The screw rod and the two connecting plates are in threaded connection. The sliding rod and the two connecting plates are in sliding connection. The upper end of the rotating shaft penetrates through the bottom wall of the workbench and extends into its inner cavity and is fixedly connected to the turntable.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) By providing the clamping device, since the fixed sleeve is slidably connected to the equipment table through the limiting sleeve, and since the upper wall of the inner cavity of the fixed sleeve is fixedly connected with an electric telescopic rod, the lower end of the electric telescopic rod is fixedly connected with a limiting block. By extending the electric telescopic rod, the workpiece can be fixed. By rotating the rotating rod, the direction of the limiting block can be adjusted, so that it can be adjusted according to the bending shape of the workpiece, and then workpieces with different bending shapes can be fixed. Moreover, the limiting block is an arc-shaped structure, making the fixation more firm and facilitating the subsequent processing by the staff.

[0014] (2) By providing the fine-tuning device, since the lower end of the turntable is movably connected to the support table through the rotating shaft, the staff can rotate the turntable, thereby adjusting the orientation of the workpiece opening, making the staff more comfortable during processing, facilitating the staff to process the workpiece, and being beneficial to improving work efficiency.

[0023] As Figures 1-4 shown, a small-diameter elbow groove processing machine tool includes a support platform 1. Four fixed columns 2 are fixedly connected to the upper end of the support platform 1. A workbench 3 is fixedly connected to the upper end of the fixed column 2. A gas cutting torch 4 is placed on the left part of the upper end of the workbench 3. A turntable 5 is slidably connected to the right part of the upper end of the workbench 3. A workpiece 6 is placed in the middle of the upper end of the turntable 5. A fine adjustment device 7 is arranged in the inner cavity of the workbench 3. An equipment platform 8 is fixedly connected to the left and right parts of the upper end of the turntable 5. A clamping device 9 is arranged in the middle of the equipment platform 8.

[0024] The clamping device 9 includes a limit sleeve 91. Fixed rods 92 are fixedly connected to both the front and rear ends of the limit sleeve 91. A fixed sleeve 93 is slidably connected to the inner cavity of the limit sleeve 91. An electric telescopic rod 94 is fixedly connected to the upper wall of the inner cavity of the fixed sleeve 93. A rotating rod 95 is fixedly connected to the upper end of the fixed sleeve 93. A nut 96 is threadedly connected to the lower part of the outer surface of the rotating rod 95. The lower end of the electric telescopic rod 94 extends below the fixed sleeve 93 and is fixedly connected to a limit block 97, which facilitates the fixation of workpieces with different bending degrees.

[0025] The limit sleeve 91 is located inside the equipment table 8. One end of each of the two fixed rods 92 away from the limit sleeve 91 is fixedly connected to the front wall and the rear wall of the inner cavity of the equipment table 8 respectively. The outer surface of the fixed rod 92 is inserted through the bottom wall of the equipment table 8. The rotating rod 95 is located above the equipment table 8.

[0026] There are two sets of clamping devices 9, which are respectively located on the left and right parts of the equipment table 8. Both of the two limit blocks 97 are arc-shaped structures. Both of the two limit blocks 97 are located above the workpiece 6. The two sets make the clamping effect better.

[0027] The fine-tuning device 7 includes a rotating shaft 71. The lower end of the rotating shaft 71 is movably connected to the support table 1 through a bearing. A screw rod 72 is movably connected to the left part of the inner cavity of the workbench 3 through a bearing. A slide rod 73 is fixedly connected to the right part of the workbench 3. A number of card slots 74 are formed on the outer surface of the turntable 5. A handle 75 is fixedly connected to the front end of the screw rod 72. Two connecting plates 76 are inserted through the outer surfaces of the screw rod 72 and the slide rod 73 together. A clamping block 77 is fixedly connected to the opposite end faces of the two connecting plates 76, which facilitates the adjustment of the orientation of the hole by the staff.

[0028] The two clamping blocks 77 are respectively clamped with the card slots 74. The screw rod 72 and the two connecting plates 76 are in threaded connection. The slide rod 73 and the two connecting plates 76 are in sliding connection. The upper end of the rotating shaft 71 penetrates through the bottom wall of the workbench 3 and extends into its inner cavity and is fixedly connected to the turntable 5.

[0029] It should be noted that the present invention is a small-diameter elbow groove processing tool. The staff first checks the equipment, then places the workpiece on the upper end of the turntable 5, then unscrews the nut 96, and then rotates the rotating rod 95. Since the fixed sleeve 93 is slidably connected to the equipment table 8 through the limit sleeve 91, and since the upper wall of the inner cavity of the fixed sleeve 93 is fixedly connected with the electric telescopic rod 94, and the lower end of the electric telescopic rod 94 is fixedly connected with the limit block 97, the limit block 97 is then rotated to change its direction and stops when it rotates to the angle corresponding to the workpiece 6. Then, the switch of the electric telescopic rod 94 is turned on, so that the electric telescopic rod 94 extends and the limit block 97 descends, and the workpiece 6 is fixed by using the limit block 97. After the fixation is completed, the switch can be turned off. Then, the nut 96 is screwed on again. Since the screw rod 72 and the slide rod 73 are jointly inserted and connected with the connecting plate 76, and the screw rod 72 is threadedly connected with the connecting plate 76, by rotating the handle 75, the connecting plate 76 moves in the opposite direction, so that the clamping block 77 leaves the clamping groove 74. Then, the staff rotates the turntable 5 to move the hole of the workpiece 6 to an appropriate angle, and then rotates the handle 75 again to insert the clamping block 77 into the clamping groove 74, and the turntable 5 can be fixed. Then, the staff uses the gas cutting torch 4 to process the workpiece 6.
