Description

Technical Field

[0001] The utility model relates to the technical field of LED display screen module testing, in particular to a punching and flanging device for an air conditioning collecting pipe. Background Art

[0002] The main function of the air-conditioning collecting pipe in the air conditioner is to collect all the gases in the evaporator, and then connect them to the external unit through the collecting pipe, so as to play a circulation role. The air-conditioning collecting pipe usually includes a main collecting pipe and several collecting branch pipes. During the production, it is necessary to open through holes on the surface of the main collecting pipe in advance to install the collecting branch pipes. The collecting branch pipes need to be welded to the through holes of the main collecting pipe. Therefore, the processing of the main collecting pipe requires the use of an existing punching machine.

[0003] Patent CN205851645U proposes a punching device, which uses a driving cylinder to drive the punching wedge to move downward. Under the action of the punching wedge, the two sliders move away from each other, that is, two opposite holes can be punched in the workpiece at the same time. The punching position is highly accurate. Compared with the existing technology, the new device can save the work of position calibration of the workpiece and improve work efficiency.

[0004] The above scheme is not applicable to the air-conditioning collecting pipe. First of all, the main collecting pipe of the air-conditioning collecting pipe is divided into straight pipe and curved pipe. The existing punching machine usually adopts clamps to fix the pipes, and the position of the clamps cannot be moved, which affects the punching of the curved main collecting pipes. In addition, the positions of the holes on the main collecting pipes are different, and the angle of the main collecting pipes needs to be adjusted frequently, which is inconvenient. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an air-conditioning air collecting pipe punching and flanging device to solve the problems raised in the above-mentioned background technology. The utility model has a novel structure. The front and rear ends of the main air collecting pipe are installed inside the clamping assembly. The clamps at the front and rear ends of the clamping assembly can move along the inside of the slide rail, and are suitable for clamping straight pipes or curved pipes with different curvatures. It can rotate to adjust the angle, which is more convenient for processing the opening positions required by different requirements.

[0006] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: an air conditioning collecting pipe punching and flanging device, comprising a base, two vertical frames are symmetrically fixed on the top of the base, and a clamping assembly is installed on the upper end surface of the vertical frame, the clamping assembly comprises a circular slide rail, two sliders are symmetrically slidably installed on the surface of the slide rail, and a lower clamping frame is provided on the top of the slider, and an upper clamping frame is provided on the top of the lower clamping frame, a punching assembly is provided on the bottom surface of the vertical frame, the punching assembly comprises a movable plate, the movable plate is slidably sleeved on the vertical frames on both sides, and a drilling device is slidably installed on the top surface of the movable plate, connecting shafts are fixed at both ends of the slide rail, and the connecting shafts are rotatably installed on the top of the vertical frame through bearings.

[0007] Furthermore, the clamping assembly also includes a limit frame, the limit frame is fixed on the top of the sliding block, and a connecting frame is slidably inserted into the limit frame, and the surface of the connecting frame is hollowed out.

[0008] Furthermore, the lower clamping frame is fixed to the top of one side of the connecting frame, the connecting frame is located at the top of the upper clamping frame and is threadedly inserted with an adjusting bolt, and the bottom of the adjusting bolt is rotatably connected to the upper clamping frame through a bearing.

[0009] Furthermore, a mounting frame is fixed on the outer side of the top of the vertical frame on one side of the base, and a driving motor is fixed on the mounting frame, and the output end of the driving motor is fixedly connected to the connecting shaft.

[0010] Furthermore, a fixing bolt is threadedly inserted on the surface of the sliding block corresponding to the inner side of the sliding rail, and one end of the fixing bolt is in compression contact with the inner wall of the sliding rail.

[0011] Furthermore, the punching assembly also includes a moving groove, the moving groove is opened on the upper end surface of the moving plate, and a moving block is slidably connected inside the moving groove, and the drilling device is installed on the top of the moving block.

[0012] Furthermore, a screw rod device is installed inside the movable groove, and the movable block is threadedly sleeved on the surface of the screw rod device.

[0013] Furthermore, an electric push rod is fixed on the side wall of the vertical frame located on the top of the movable plate, and the extended end of the electric push rod is fixedly connected to the movable plate.

[0014] Beneficial effects of the utility model:

[0015] 1. The movable plate of the utility model is controlled by an electric push rod to move up and down along the vertical frame. Each time the clamping assembly is rotated, the movable plate slides downward to provide space for the rotation of the slide rail. After the rotation angle is adjusted, the electric push rod can push the drilling device onto the surface of the main collecting pipe to punch holes.

[0016] 2. The utility model drives the slide rail to flip a certain angle through the connecting shaft by the driving motor to correspond to the position of the main air collecting pipe that needs to be processed.
