[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: a detection tool for the length of the flat tube of an electric vehicle air conditioner heat pump microchannel heat exchanger, including a workbench 1 and a support leg 2. A baffle 3 is fixedly installed in the middle of the top of the workbench 1. At the same time, a chute 6 is opened at one end of the top of the workbench 1, and a groove 8 is opened at the other end of the top of the workbench 1. A stop block 9 is slidably connected to the inner wall of the chute 6. A spring 10 is fixedly connected to the inner side of the stop block 9 and on one side inside the chute 6. A positioning component 7 is slidably connected to the inner wall of the groove 8, and a scale 5 is arranged on one side of the baffle 3 and respectively inside the positioning component 7 and the stop block 9.

[0023] Through the workbench 1, the baffle 3 can be installed. Since chutes 6 and grooves 8 are opened at both the left and right ends of the top of the workbench 1, and a stop block 9 and a positioning component 7 are respectively slidably connected to the inside of the chute 6 and the groove 8. At the same time, a scale 5 is arranged on one side of the baffle 3 and respectively inside the positioning component 7 and the stop block 9. Thus, when measuring the length of the aluminum flat tube, during use, the stop block 9 is pulled, so that the stop block 9 slides along the inner wall of the chute 6. At this time, the spring 10 is stretched, and the distance between the chute 6 and the baffle 3 gradually increases. At this time, the aluminum flat tube is placed inside the stop block 9, and the stop block 9 is loosened. Under the elastic action of the spring 10, the stop block 9 is driven to reset. Furthermore, the stop block 9 can initially position the aluminum flat tube, and by adjusting the positioning component 7 to move along the inside of the groove 8, the aluminum flat tube can be fixed and contact with one side of the baffle 3. At this time, observing the scale 5 can accurately measure the length of the aluminum flat tube.

[0024] Refer to Figure 1 , Figure 2 , the baffle 3 is in a "U" shape, and two brackets 4 are fixedly installed on the top of the baffle 3. At the same time, a fluorescent lamp is installed on the top of the bracket 4. Both the positioning component 7 and the stop block 9 are two, and the two positioning components 7 and the two stop blocks 9 are respectively located on the front and back sides of the baffle 3.

[0025] Through the baffle 3, two brackets 4 can be installed. Since a fluorescent lamp is installed at the top of the bracket 4, the fluorescent lamp can ensure sufficient lighting in the working area, thereby improving the measurement accuracy. And since the number of the positioning components 7 and the stoppers 9 is two each, and the two positioning components 7 and the two stoppers 9 are respectively located on the front and rear sides of the baffle 3, the two positioning components 7 and the stoppers 9 enable the workbench 1 to measure two aluminum flat tubes, thereby improving the measurement rate of the aluminum flat tubes.

[0026] Refer to Figure 3 、 Figure 4 The positioning component 7 includes a screw rod 701. The screw rod 701 is sleeved on the inner wall of the workbench 1 and penetrates through the groove 8. A convex block 702 is slidably connected to the outer wall of the screw rod 701 and inside the groove 8. At the same time, a clamping plate 704 is fixedly installed at the top of the convex block 702 and on the top of the workbench 1. One end of the screw rod 701 penetrates through one side of the workbench 1. At the same time, a handle 703 is fixedly installed at one end of the screw rod 701 and on one side of the workbench 1. And the outer surface of the handle 703 is concave-convex.

[0027] Through the screw rod 701 in the positioning component 7, the convex block 702 and the handle 703 can be installed. Since the clamping plate 704 is fixedly installed at the top of the convex block 702, by rotating the handle 703, the screw rod 701 can be driven to rotate. At this time, under the action of the thread of the convex block 702, the convex block 702 drives the clamping plate 704 to move along the groove 8, thereby fixing the aluminum flat tube.

[0028] Refer to Figure 3 、 Figure 4 Two limiting rods 81 are fixedly installed on the inner wall of the groove 8. And the two limiting rods 81 are inserted into the inner wall of the convex block 702. At the same time, an anti-corrosion coating is applied to the outer surfaces of the two limiting rods 81 and the screw rod 701. Rubber pads are wrapped on the outer surfaces of the chute 6 and the clamping plate 704.

[0029] By inserting the two limiting rods 81 into the inner wall of the convex block 702, when the screw rod 701 is rotated, the convex block 702 moves along the groove 8 and the two limiting rods 81 respectively, driving the clamping plate 704 to move, thereby enabling the clamping plate 704 to fix the aluminum flat tube. At the same time, since rubber pads are wrapped on the outer surfaces of the stopper 9 and the clamping plate 704, the rubber pads can absorb and disperse vibration energy, thus avoiding damage when the stopper 9 and the clamping plate 704 fix the aluminum flat tube.

[0030] During operation, the baffle 3 can be installed through the workbench 1. Since sliding grooves 6 and grooves 8 are provided at both the left and right ends of the top of the workbench 1, and a stop block 9 and a positioning component 7 are respectively slidably connected inside the sliding groove 6 and the groove 8. At the same time, a scale 5 is provided on one side of the baffle 3 and inside the positioning component 7 and the stop block 9 respectively. Therefore, when measuring the length of the aluminum flat tube, during use, the stop block 9 is pulled, so that the stop block 9 slides along the inner wall of the sliding groove 6. At this time, the spring 10 is stretched, and at the same time, the distance between the sliding groove 6 and the baffle 3 gradually increases. At this time, the aluminum flat tube is placed inside the stop block 9, and the stop block 9 is loosened. Under the elastic action of the spring 10, the stop block 9 is driven to reset. Furthermore, the stop block 9 can initially position the aluminum flat tube, and by adjusting the positioning component 7 to move along the inside of the groove 8, the aluminum flat tube can be fixed and contact with one side of the baffle 3. At this time, observing the scale 5 can accurately measure the length of the aluminum flat tube.

[0031] Through the baffle 3, two brackets 4 can be installed. Since a fluorescent lamp is installed on the top of the bracket 4, the fluorescent lamp can ensure sufficient lighting in the working area, thereby improving the measurement accuracy. And since the number of the positioning components 7 and the stop blocks 9 is two each, and the two positioning components 7 and the two stop blocks 9 are respectively located on the front and back sides of the baffle 3, the two positioning components 7 and the stop blocks 9 enable the workbench 1 to measure two aluminum flat tubes, thereby improving the measurement rate of the aluminum flat tube.

[0032] Through the screw 701 in the positioning component 7, the convex block 702 and the handle 703 can be installed. Since a clamping plate 704 is fixedly installed on the top of the convex block 702, rotating the handle 703 can drive the screw 701 to rotate. At this time, under the action of the thread of the convex block 702, the convex block 702 drives the clamping plate 704 to move along the groove 8, thereby being able to fix the aluminum flat tube.

[0033] By inserting two limiting rods 81 into the inner wall of the convex block 702, rotating the screw 701 makes the convex block 702 move along the groove 8 and the two limiting rods 81 respectively, and drives the clamping plate 704 to move, thereby enabling the clamping plate 704 to fix the aluminum flat tube. At the same time, since rubber pads are wrapped on the outer surfaces of the stop block 9 and the clamping plate 704, the rubber pads can absorb and disperse vibration energy, thereby avoiding damage when the stop block 9 and the clamping plate 704 fix the aluminum flat tube.

[0034] In summary, the device pulls the stop block 9 and slides along the inner wall of the sliding groove 6. At this time, the distance between the sliding groove 6 and the baffle 3 gradually increases. The aluminum flat tube is placed inside the stop block 9, and the stop block 9 is loosened. Under the elastic action of the spring 10, the stop block 9 is driven to reset. Furthermore, the stop block 9 can initially position the aluminum flat tube, and by adjusting the positioning component 7 to move along the inside of the groove 8, the aluminum flat tube can be fixed. Observing the scale 5 can accurately measure the length of the aluminum flat tube.
