[0008] Preferably, the workbench has a feeding hole inside, and sliding grooves are provided on both sides inside the workbench. A second spring is fixedly connected inside each sliding groove, and a clamping plate is fixedly connected to the other end of the second spring.

[0009] Preferably, one end of the card plate is arc-shaped, and the arc ends of the two card plates on both sides correspond to each other.

[0013] (III) Beneficial Effects

[0014] This utility model provides a punching device for the upper left mounting bracket of an automotive air conditioning unit. It has the following advantages:

[0015] (1) Fix the bracket on the workbench and start the electric hydraulic rod at the top of the bracket. It pushes the connecting plate down, causing the punch head and pressure plate to move down together. When the punch head touches the workpiece, the pressure plate is pressed up by the reaction force, and the slide rod moves up to stretch the first spring. During punching, the waste material is pushed into the discharge hole. During this process, the punch head pushes open the clamping plate, allowing it to slide in the slide groove and squeeze the second spring. The waste material falls into the collection box. When the punch head moves up, if there is waste material attached, the clamping plate will stick to the punch head under the action of the second spring, and the waste material will be clamped by the clamping plate. During the next punching, the waste material falls off with the new waste material. Before the punch head leaves the workpiece, the pressure plate presses the workpiece tightly to prevent the workpiece from moving up. This device solves the problems of inconvenient waste cleaning and easy workpiece displacement in existing punching devices. The waste material generated by punching in traditional devices often accumulates, affecting operation, and the workpiece is not fixed firmly and is easy to move, resulting in low processing accuracy. This structure achieves automatic waste removal through the cooperation of its various components, while the pressure plate ensures workpiece stability, improving processing accuracy and efficiency, guaranteeing processing quality, and reducing the time and effort required for manual waste removal.

[0016] (2) Start the motor on the mounting plate. The motor drives the bidirectional threaded rod to rotate. The connecting brackets at both ends of the bidirectional threaded rod move in opposite directions under its rotation. When the connecting brackets move, they drive the clamping plate to move in the opposite direction, thereby clamping and positioning the workpiece. During the movement of the clamping plate, the rollers installed on the clamping plate can roll on the positioning rod, which plays an auxiliary role in movement and guidance, making the movement of the clamping plate smoother. At the same time, the limit rod limits the connecting bracket, ensuring that the connecting bracket and the clamping plate move in the predetermined direction and preventing deviation. This device solves the problems of unstable workpiece clamping and inaccurate positioning in existing devices. Traditional workpiece clamping devices may experience uneven force during clamping, leading to workpiece slippage and shaking, which affects the processing accuracy. This structure achieves stable clamping through the cooperation of the motor, bidirectional threaded rod, connecting bracket and clamping plate. The rollers and positioning rod make the movement of the clamping plate more flexible, and the limit rod ensures the accuracy of movement, effectively avoiding the slippage and shaking of the workpiece during processing, improving processing accuracy and quality, and increasing work efficiency.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] Example 1: A punching device for a mounting bracket on the upper left side of an automotive air conditioning unit, comprising a workbench 1, a bracket 2 fixedly connected to the top of the workbench 1, an electro-hydraulic rod 3 fixedly connected to the top of the bracket 2, a connecting plate 4 fixedly connected to the output end of the electro-hydraulic rod 3, a punching head 5 fixedly connected to the bottom of the connecting plate 4, a pair of sliding rods 7 slidably connected inside the connecting plate 4, a pressure plate 6 fixedly connected to the bottom of the workbench 1, a limit ring 9 fixedly connected to the top of the sliding rods 7, and a spring 8 fixedly connected between the limit ring 9 and the connecting plate 4, while the spring 8 is sleeved on the outer wall of the sliding rod 7. The workbench 1 has a feeding hole 14 inside. Both sides of the workbench 1 have sliding grooves 11. Each sliding groove 11 is fixedly connected to a spring 12. The other end of the spring 12 is fixedly connected to a clamping plate 13. One end of the clamping plate 13 is arc-shaped, and the arc ends of the two clamping plates 13 correspond to each other. The inner diameter between the arc ends of the two clamping plates 13 is smaller than the inner diameter of the feeding hole 14. At the same time, the clamping plate 13 is slidably connected in the sliding groove 11. A pair of limiting rods 23 are fixedly connected to the top of the connecting plate 4, and the limiting rods 23 are slidably connected in the bracket 2. A collection box 15 is set inside the workbench 1.

[0025] The electric hydraulic rod 3 at the top of the starter bracket 2 pushes the connecting plate 4 downward, causing the punch head 5 and pressure plate 6 to move downward synchronously. When the punch head 5 contacts the workpiece, the pressure plate 6 is compressed upward by the reaction force, and the slide rod 7 moves upward accordingly, pulling the spring between the limit ring 9 and the connecting plate 4. When the punch head 5 punches the workpiece, the generated waste material is pushed into the discharge hole 14. Before entering the discharge hole 14, the waste material passes through the clamping plate 13. When the punch head 5 moves downward, it pushes the clamping plate 13 to both sides, causing the clamping plate 13 to slide in the slide groove 11 and squeeze the second spring 12. At this time, the waste material falls into the collection box 15 through the discharge hole 14. When the punch head 5 moves upward, if there is waste material attached, the clamping plate 13 will stick tightly to the outer wall of the punch head 5 under the elastic action of the second spring 12. When the waste material passes through the clamping plate 13, it is clamped by the clamping plate 13 and stuck between the two clamping plates 13. During the next punching, it falls into the collection box 15 along with the waste material. Before the punching head 5 is separated from the workpiece, the pressure plate 6 will press the workpiece tightly to prevent the workpiece from moving upward with the punching head 5. Through the cooperation of components such as the electric hydraulic rod 3, connecting plate 4, punching head 5, pressure plate 6, and clamping plate 13, the waste material is quickly cleaned up, effectively improving work efficiency.

[0026] Example 2: The difference between this example and Example 1 is that, in this example, a pair of mounting plates 16 are fixedly connected to the outer walls of both sides of the workbench 1, a motor 17 is fixedly connected to the outer wall of one mounting plate 16, a bidirectional threaded rod 18 is fixedly connected to the output end of the motor 17, a pair of clamping plates 20 are slidably connected to the top of the workbench 1, and multiple rollers 21 are rotatably connected to the inner wall of each clamping plate 20. A connecting frame 19 is fixedly connected to both sides of each clamping plate 20, one connecting frame 19 is threadedly connected to the outer wall of the bidirectional threaded rod 18, and a positioning rod 22 is fixedly connected inside the mounting plate 16 on the other side, and the other connecting frame 19 is slidably connected to the outer wall of the positioning rod 22.

[0027] The bracket is placed on top of the worktable 1, and then the motor 17 on the outer wall of the mounting plate 16 is started. The motor 17 rotates, driving the bidirectional threaded rod 18 to rotate. As the bidirectional threaded rod 18 rotates, the connecting brackets 19 at both ends move in the opposite direction under the action of the threads. Simultaneously, the connecting brackets 19 move, driving the connected clamping plate 20 to move in the opposite direction as well. This reverse movement of the clamping plate 20 achieves the clamping and positioning of the upper left mounting bracket of the automotive air conditioning unit. During the movement of the clamping plate 20, the connecting bracket 19 on the other side acts as a limit, ensuring the stable movement of the clamping plate 20. The coordinated operation of these components—the motor 17, the bidirectional threaded rod 18, the connecting brackets 19, and the clamping plate 20—effectively prevents the workpiece from slipping and wobbling during processing, improving the positioning accuracy of the workpiece, thereby improving the processing quality and ensuring the smooth progress of the processing work and the accuracy of the processing results.

[0028] Working principle: When the operator needs to punch holes in the upper left mounting bracket of the car air conditioning unit, the bracket is first placed on the top of the workbench 1. Then, the motor 17 on the outer wall of the mounting plate 16 is started. The motor 17 drives the bidirectional threaded rod 18 to rotate. As the bidirectional threaded rod 18 rotates, it drives the connecting brackets 19 at both ends to move in the opposite direction. When the connecting brackets 19 move, they drive the clamping plate 20 to move in the opposite direction, thus clamping and positioning the upper left mounting bracket of the car air conditioning unit. The clamping plate 20 is limited by the connecting bracket 19 on the other side during movement. Through their cooperation, slippage and shaking of the workpiece during processing are prevented, improving processing quality. After fixing, the electro-hydraulic rod 3 on the top of the bracket 2 is started. Under the action of the electro-hydraulic rod 3, the connecting plate 4 is pushed down, and the punching head 5 and the pressure plate 6 are moved down together. When the punching head 5 touches the workpiece, the pressure plate 6 is... The upward compression and upward movement of the slide bar 7 pull the spring between the limiting ring 9 and the connecting plate 4. When the limiting ring 9 punches the workpiece, the waste material is pushed into the discharge hole 14. Before being pushed, it passes through the clamping plate 13, and the punching head 5 pushes the clamping plate 13 to both sides, causing the clamping plate 13 to slide in the slide groove 11 and squeeze the second spring 12. At this time, the waste material falls into the collection box 15 through the discharge hole 14 for collection. When the waste material is attached to the punching head 5, when the punching head 5 moves upward, the clamping plate 13 will be tightly attached to the outer wall of the punching head 5 by the elasticity of the second spring 12. When the waste material passes through the clamping plate 13, it will be clamped by the clamping force of the clamping plate 13 and stuck between the two clamping plates 13. It will fall into the collection box 15 together during the next punching. Before the punching head 5 is separated from the workpiece, the pressure plate 6 will press the workpiece tightly to prevent it from moving upward with the punching head 5. Through their cooperation, the waste material is quickly cleaned up, improving work efficiency.
