Description

Technical Field

[0001] The utility model relates to the technical field of automobile air-conditioning valve sheet processing, in particular to an automobile air-conditioning valve sheet punching device. Background Art

[0002] The automobile air conditioning valve is one of the key components in the automobile air conditioning system. It mainly controls the flow of refrigerant, thereby realizing the cooling, heating and ventilation functions of the air conditioning system. During the production and processing of the valve, a punching device is required to perform punching operations on the valve.

[0003] However, the current punching device is rather troublesome to use. After punching is completed, the punched valve sheet needs to be removed manually. The edge of the valve sheet after punching is relatively sharp, which may easily cause danger. In addition, the clamp cannot be adjusted according to the size of the valve sheet during use, which may easily lead to deviation in punching and affect the processing quality.

[0004] For example, the publication number "CN218982853U" provides an automobile air-conditioning valve plate punching device. The device has a positioning component. When in use, the gasket and the spring can be pressed down at the same time by pulling the traction rope, so that the positioning block is moved out of the slot and the valve plate is fixed to avoid displacement during the punching process. At the same time, the cooperation of multiple positioning blocks facilitates the pushing of the valve plate to the center position in the placement slot, reducing the possibility of deviation in the punching position of the valve plate, and ensuring the processing accuracy of the punching operation of the valve plate.

[0005] However, the above device still has the following problems during implementation:

[0006] When the device is in use, although the valve plate can be fixed, the size of the placement groove of the device is limited and cannot be adjusted according to the size of the valve plate, and the scope of application is relatively limited. Although the device is provided with a waste discharge channel, since a mounting rod and a support rod are provided in the placement groove, the waste generated during punching is easily blocked by the mounting rod or the support rod when falling downwards and stuck in the placement groove and cannot fall, thereby affecting the subsequent punching work.

A limit slot 16 is provided on the top of the operating table 1, and the limit slot 16 is located directly below the adjusting screw 32. A scale line is also provided on the limit slot 16. A sliding block 34 is fixedly installed at the bottom of the limit plate 33, and the sliding block 34 is slidably connected to the limit slot 16. A rotating block 35 is also fixedly installed at one end of the rotating cylinder 31 away from the adjusting screw 32. The stamping assembly includes a stamping machine 21. The output end of the stamping machine 21 passes through the top of the stamping table 2 and extends between the stamping table 2 and the operating table 1. A punching drill 22 is fixedly connected to the output end of the stamping machine 21. The diameter of the punching drill 22 is the same as the diameter of the discharge port 12.

[0027] When using the device, firstly rotate the rotating block 35 so that the rotating block 35 drives the rotating cylinder 31 to rotate. When the rotating cylinder 31 rotates, the adjusting screw 32 in the rotating cylinder 31 moves outward along the rotating cylinder 31, driving the limit plate 33 to slide on the operating table 1. Through the limit groove 16 provided on the operating table 1, when the limit plate 33 slides, the sliding block 34 at the bottom of the limit plate 33 will follow the limit plate 33 to slide in the limit groove 16, so that the movement of the limit plate 33 is more stable. Through the scale line provided on the limit groove 16, the adjustment length can be controlled, so that the adjustment of the limit plate 33 is more precise.

[0028] After the limit plate 33 is adjusted to a suitable position, the valve plate is placed on the processing table 11 so that the valve plate abuts against the limit plate 33, and the punching machine 21 is started to drive the punching drill 22 to move downward, and the punching drill 22 punches holes in the valve plate;

[0029] By setting the pusher assembly 4, after the punching is completed, the pusher assembly 4 is started, and the valve sheet can be pushed out from the processing table 11 by the pusher assembly 4. After being pushed out, the valve sheet that needs to be punched is placed on the processing table 11 to continue working.

[0030] For example 2, please refer to Figure 1-4The push assembly 4 includes a sliding rack 41, a push plate 42 is fixedly installed on one side of the sliding rack 41 close to the processing table 11, the sliding rack 41 and the push plate 42 are both slidably connected to the top of the operating table 1, and a limit frame 43 is also fixedly installed on the top of the operating table 1. The sliding rack 41 is slidably inserted in the limit frame 43, and a transmission gear 45 is rotatably connected in the limit frame 43 near the teeth of the sliding rack 41, and the transmission gear 45 is meshed with the sliding rack 41.

[0031] A controller (not shown in the figure) for controlling the punching machine 21, the servo motor 44 and the drive motor is provided at the bottom of the operating table 1. When the punching is completed, the servo motor 44 and the drive motor are started by the controller (the controller starting principle is a prior art and will not be elaborated here), so that the servo motor 44 drives the transmission gear 45 to rotate. When the transmission gear 45 rotates, the sliding rack 41 meshing with the transmission gear 45 drives the push plate 42 to slide in the limit frame 43 under the action of the transmission gear 45, so that the push plate 42 moves toward the direction of the processing table 11, and the valve sheet on the processing table 11 is pushed by the push plate 42, so that the valve sheet is pushed out of the processing table 11 and falls on the conveyor belt 14. The conveyor belt 14 rotates continuously under the action of the drive motor to move the valve sheet, and moves to the end and falls into the valve sheet collection box 5 for collection;

[0032] At the same time, after the punching is completed, the waste generated during the punching falls downward through the discharge port 12 and falls into the waste collection box 6 through the discharge pipe 15 for unified collection, which is convenient for subsequent processing;

[0034] Working principle: When using the device, first rotate the rotating block 35, so that the rotating block 35 adjusts the position of the adjusting screw 32 and the limit plate 33 through the rotating cylinder 31, and moves the limit plate 33 to a suitable position according to the diameter of the valve plate. After the movement is completed, start the driving motor in the operating table 1 through the controller, so that the driving motor drives the conveyor belt 14 to rotate;

[0036] After the punching is completed, the servo motor 44 is started, and the servo motor 44 drives the transmission gear 45 to rotate, so that the sliding rack 41 slides in the limit frame 43 toward the processing table 11, so that the push plate 42 pushes the valve sheet on the processing table 11, and the valve sheet is pushed out from the processing table 11 and falls on the conveyor belt 14. The conveyor belt 14 continues to rotate under the action of the driving motor, transports the valve sheet, and moves the valve sheet to the end and falls into the valve sheet collection box 5 for collection;

[0037] At the same time, after the punching is completed, the waste generated during the punching falls downward through the discharge port 12 and falls into the waste collection box 6 through the discharge pipe 15 for unified collection, which is convenient for subsequent processing.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
