[0021] The structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] As Figures 1 to 4 shown, the adjustable fixture for air-conditioning copper tube processing provided by the embodiment of the present invention includes a substrate 1 and mounting ears 2.

The number of clamping components 32 is two, and they are respectively arranged at the front and rear ends above the moving component 31.

[0024] Adopting the above solution: By setting the fixing device 3, it is used to fix the copper tube, and when the copper tube is cut or welded, etc., it can support and fix the copper tube, avoiding the situation that the copper tube is offset and unstable, which is not easy to process.

[0025] Referring to Figure 1 and Figure 2, the moving component 31 includes a fixed block 311, a baffle 312, a sliding rod 313, a screw rod 314 and a moving block 315. The fixed block 311 is fixedly connected to one side of the upper surface of the substrate 1. The baffle 312 is arranged directly in front of the fixed block 311, and the lower end is fixedly connected to the upper surface of the substrate 1. The number of sliding rods 313 is two, and they are respectively arranged on the left and right sides at the front end of the fixed block 311. The front and rear ends of the two sliding rods 313 are respectively fixedly connected to the front surface of the fixed block 311 and the rear surface of the baffle 312. The screw rod 314 is arranged between the two sliding rods 313, the front end is rotatably connected to the front surface of the fixed block 311, and the rear end penetrates through the baffle 312 and is rotatably connected to the baffle 312. The moving block 315 is sleeved on the surfaces of the two sliding rods 313 and the screw rod 314, and is slidably connected to the two sliding rods 313 and is threadedly connected to the screw rod 314.

[0026] Adopting the above solution: By setting the moving component 31, it is used to drive the clamping component 32, and has the function of driving the clamping component 32 to move horizontally, so as to clamp and fix the copper tube.

[0027] Reference Figure 2 And Figure 3 , the two clamping components 32 are respectively fixedly connected to the upper surfaces of the fixed block 311 and the moving block 315. The clamping component 32 includes a clamping block 321, a fixed shaft 322 and a roller 323. The two clamping blocks 321 are respectively fixedly connected to the upper surfaces of the fixed block 311 and the moving block 315. The number of fixed shafts 322 is three, and they are respectively evenly arranged inside the clamping block 321. The upper and lower ends of the fixed shaft 322 are respectively fixedly connected to the upper and lower ends inside the clamping block 321. The number of rollers 323 is three, and they are sleeved on the surfaces of the three fixed shafts 322 and are rotatably connected to the fixed shafts 322.

[0028] Adopting the above solution: By setting the clamping component 32, it is used to clamp and fix the copper tube, and has the function of being able to move the copper tube left and right while clamping the copper tube, avoiding the situation that the traditional clamping tool cannot move and adjust after clamping the copper tube, so as to facilitate the movement and adjustment of the cutting or welding position.

[0029] Reference Figure 1 And Figure 4 , the alignment component 4 is provided with a fixed seat 41 and a marking head 42. The fixed seat 41 is arranged at the rear end in the middle of the two fixing devices 3, and the lower end is fixedly connected to the upper surface of the substrate 1. The marking head 42 is fixedly connected to the upper end of the front surface of the fixed seat 41.

[0030] Adopting the above solution: By setting the alignment component 4, it is convenient for the staff to adjust the clamped copper tube and align the position to be cut or welded during cutting or welding, thus playing a role of reference and alignment.

[0031] Reference Figure 2 One end of the screw rod 314 passing through the baffle 312 is provided with a knob 5, and the knob 5 is fixedly connected to the screw rod 314.

[0032] With the above solution: By providing the knob 5 at one end of the screw rod 314 passing through the baffle 312, it is used to rotate the screw rod 314, which is convenient for rotating the screw rod 314 to control the fixing device 3.

[0033] Reference Figure 2 and Figure 3 The material of the roller 323 is rubber, and a clamping block 321 extends from one side surface of the roller 323.

[0034] With the above solution: By making the material of the roller 323 rubber, when clamping the copper pipe, it has a certain buffer, and it can avoid damaging the copper pipe when clamping or moving the copper pipe left and right for adjustment.

[0035] The working principle of the present utility model:

[0036] During use, place the copper pipe between the two clamping components 3 between the two clamping components 32, and then rotate the knob 5. While the knob 5 rotates, it drives the screw rod 314 to rotate between the fixed block 311 and the moving block 315. While the screw rod 314 rotates, it drives the moving block 315 threadedly connected to it to move backward on the surface of the sliding rod 313. The movement of the moving block 315 drives the clamping block 321 to move, clamping the copper pipe between the two clamping blocks 321. When clamping, the surface of the roller 323 contacts the surface of the copper pipe for clamping. When adjusting the position after clamping, by moving the clamped copper pipe left and right, when moving and adjusting the clamped copper pipe, due to the reason of clamping and extrusion, the roller 323 will rotate on the surface of the fixed shaft 322 through the movement of the copper pipe, so as to adjust the position of the clamped copper pipe. Then, the cutting or welding position of the copper pipe can be moved and adjusted to align with the alignment head 42 to calibrate the position, thus completing the clamping and fixing and adjustment.

[0037] In summary: The adjustable fixture for air-conditioning copper pipe processing, through the combined use of the base plate 1, mounting ears 2, fixing device 3, moving component 31, fixed block 311, baffle 312, sliding rod 313, screw rod 314, moving block 315, clamping component 32, clamping block 321, fixed shaft 322, roller 323, alignment component 4, fixed seat 41, alignment head 42 and knob 5, solves the problem that when the existing fixture clamps and fixes the air-conditioning copper pipe for processing, the clamped copper pipe is usually fixed firmly. In this way, when adjusting the cutting or welding position of the copper pipe, and when performing the next section of cutting, it is necessary to re-control the opening and closing of the fixture, so it will be more troublesome, which will in turn lead to inconvenience in processing and affect work efficiency.
