Description

Technical Field

[0001] The utility model relates to the technical field of testing tooling, in particular to a driving board testing tooling. Background Art

[0002] The air conditioner driver board is the control center of the air conditioner compressor, which is mainly responsible for controlling and regulating the operation of the compressor to achieve the normal operation of the air conditioning system. It is usually composed of a main control chip, a driver chip, a power chip, etc., and has multiple protection functions, such as overvoltage protection, undervoltage protection, overcurrent protection, etc. During use, various faults may occur on the driver board, such as open circuit, short circuit, overheating, etc. If these faults occur, they need to be checked and repaired and replaced in time. During the maintenance process, the worker needs to test the driver board. Generally, the driver board is installed in the air conditioner chassis.

[0003] When testing the existing air-conditioning driver board, a multimeter is often used to detect the resistance value of each connector on the driver board. However, when the driver board is taken out from the inside of the chassis, there will be a line connection. When pulled out, the line itself has a certain deformable supporting force, so it cannot be placed stably and flat on the ground. During the inspection process, the worker needs to hold the inspection terminal with both hands to test the surface of the driver board, so there is no hand to hold the driver board, which easily leads to inconvenience in the inspection process. For this reason, we propose a driver board test tooling. Utility Model Content

[0009] In a further technical solution, threaded sleeves are fixedly installed on both side walls of the bottom end of the hanging plate, the inner wall of the threaded sleeve is threadedly connected to a threaded support rod, and an upwardly extending top rod is fixedly installed on one end of the threaded support rod away from the threaded sleeve, and the support member includes a top rod and a support plate, and the support plates are fixedly installed on both side walls of the bottom end of the rotating plate, and the top surface of the top rod is tightly fitted with the bottom surface of the support plate.

[0010] In a further technical solution, the threaded support rod is normally hung on the two side walls of the hanging plate, and the threaded support rod is flipped counterclockwise for use.

[0011] In a further technical solution, a recess is formed on a side of the box door facing the box body, and the surface of the stopper is tightly fitted with an inner wall of the recess.

[0012] The beneficial effects of the utility model are:

[0013] Through the setting of the device, when the driving plate is tested, the box body is opened, and then the five-sided bolt is inserted into the inner wall of the five-sided groove and rotated, so that the screw rod rotates, and then the hanging plate moves horizontally under the guidance of the guide block and the slider until the hanging plate moves to the opening of the box body. During the process, the driving plate can be kept stable. When the driving plate is located at the opening of the box body, the screw rod is stationary, and the threaded mouth can be stuck with the tooth groove on the surface of the screw rod, thereby maintaining the test stability of the driving plate, and the overall structure is convenient for operation.

[0022] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0023] Example:

[0024] like Figure 1-Figure 6 As shown, the driving plate test fixture includes a box body 1 and a driving plate 13. A box door 2 is hinged on the surface of the box body 1. The inner wall of the box body 1 is connected to a mounting plate 3 through a threaded bolt 4. A hanging plate 5 is provided at the center of the surface of the mounting plate 3. A sliding rod 6 is fixedly installed on the surface of the mounting plate 3. A stopper 7 is fixedly installed at one end of the sliding rod 6 away from the mounting plate 3. The diameter of the stopper 7 is larger than the diameter of the sliding rod 6. A bearing 8 located below the sliding rod 6 is inserted on the surface of the mounting plate 3. A screw rod 9 is fixedly installed on the inner wall of the bearing 8. The sliding rod 6 and the screw rod 9 are relatively parallel. A slider 10 and a guide block 11 are fixedly installed at the upper and lower ends of the hanging plate 5, respectively. A threaded opening 12 is provided on the surface of the guide block 11 for threaded cooperation with the screw rod 9, the slider 10 and the slide rod 6 are slidably cooperated, a pentagonal groove 14 is provided on the end of the screw rod 9 away from the mounting plate 3, a pentagonal bolt 15 is inserted into the inner wall of the pentagonal groove 14, a turning handle 16 is fixedly installed on the end of the pentagonal bolt 15 away from the pentagonal groove 14, the pentagonal bolt 15 and the turning handle 16 are T-shaped, the driving plate 13 is fixed at the center of the surface of the hanging plate 5, a notch 25 is provided on the side of the box door 2 facing the box body 1, the surface of the stopper 7 is tightly fitted with the inner wall of the notch 25, so as to prevent the box door 2 from being unable to be closed due to the stopper 7 when it is closed on the surface of the box body 1.

[0025] The working principle of the above technical solution is as follows:

[0026] When using the device, first open the box door 2 on the surface of the box body 1, then insert the five-sided bolt 15 on one side of the handle 16 into the end of the screw rod 9, keep the insertion stable, and then start to turn the handle 16 to let the screw rod 9 rotate on the inner wall of the bearing 8. During this process, the rotation of the screw rod 9 can move the hanging plate 5 horizontally. When the hanging plate 5 moves to the opening of the box body 1, the moving space will be restricted by the block 7. At this time, the rotation operation of the screw rod 9 can be stopped, and the drive plate 13 can be directly tested.

[0027] In another embodiment, if Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a groove 17 is provided at the center of the surface of the hanging plate 5, and a rotating plate 18 is provided on the inner wall of the groove 17. The driving plate 13 is located on the surface of the rotating plate 18, and the top of the rotating plate 18 is hinged to the groove 17. Both sides of the top wall of the hanging plate 5 are fixedly installed with hinge blocks 19, and the bottom ends of the hinge blocks 19 are located on both sides of the top opening of the groove 17. Both sides of the top of the rotating plate 18 are fixedly installed with hinge bolts 20, and the hinge bolts 20 are rotatably matched with the bottom ends of the hinge blocks 19. By setting the groove 17 and the rotating plate 18, the driving plate 13 can have a position The effect of moving and flipping is improved, and the convenience of testing work is improved. Threaded sleeves 21 are fixedly installed on both side walls of the bottom end of the hanging plate 5. The inner wall of the threaded sleeve 21 is threadedly connected with a threaded support rod 22. The end of the threaded support rod 22 away from the threaded sleeve 21 is fixedly installed with an upwardly extending push rod 23. The bottom end of the rotating plate 18 is fixedly installed with a supporting plate 24 on both side walls. The top surface of the push rod 23 is tightly fitted with the bottom surface of the supporting plate 24. The threaded support rod 22 is normally hung on the two side walls of the hanging plate 5, and the threaded support rod 22 is used for counterclockwise flipping.

[0028] When in use, first flip the bottom of the rotating plate 18 upwards, then pull the threaded support rod 22 upwards with the threaded sleeve 21 as the rotation point. During the process, the threaded support rod 22 and the threaded sleeve 21 are threadedly fastened, and then the top rod 23 is located on the top front side of the hanging plate 5, and then the rotating plate 18 is loosened to allow the support plate 24 to rest on the top of the top rod 23.

[0029] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
