Technical Field

[0001] This utility model relates to the field of parts processing, and in particular to a safety protection device for a pneumatic drilling machine. Background Technology

[0002] Pneumatic drilling machines, powered by compressed air, offer numerous advantages. They provide stable power output, high drilling efficiency, and ensure the accuracy and consistency of hole positions in mass production. They are easy to operate and highly safe, lightweight and user-friendly, and equipped with safety protection devices to prevent electric shock and misoperation risks. Maintenance is simple and cost-effective, with pneumatic components experiencing less wear and a lower failure rate. Long-term operating costs are lower than some electric devices. Furthermore, they are widely applicable and highly flexible, compatible with various soft and hard materials. They can meet the needs of mass production in factories as well as small workshops or temporary outdoor processing, making them an ideal alternative to manual and some electric drilling equipment in small and medium-sized processing scenarios.

[0003] When traditional pneumatic drilling machines process hard materials such as thin metal sheets, their inherent elasticity becomes a key obstacle affecting the drilling quality. Although thin metal sheets are hard, they are prone to elastic deformation on both sides when pressed down, resulting in poor drilling quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a safety protection device for a pneumatic drilling machine, which solves the problem of deformation that easily occurs when traditional pneumatic drilling machines process thin metal sheets.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for a pneumatic drilling machine, comprising a worktable, two sliding grooves installed on the upper surface of the worktable, a placement frame installed on the upper surface of the two sliding grooves, a connecting groove on the bottom surface of the placement frame, observation ports on both the left and right sides of the placement frame, an electric telescopic rod installed on the outer surface of the placement frame, a connecting plate connected to the output end of the electric telescopic rod, two push rods connected to the outer surface of the connecting plate, a push bar installed at the end of the two push rods away from the connecting plate, and the outer surface of the push bar slidably connected to the inside of the sliding groove.

[0006] As a further technical solution of this utility model, a support frame is installed on the upper surface of the workbench, an infrared detection device is installed on the inner wall of the support frame, two support columns are installed on the upper surface of the support frame, and a support plate is installed on the end of the two support columns away from the support frame.

[0007] As a further technical solution of this utility model, a circular hole is provided on the outer surface of the support plate, and a punching machine body is installed on the upper surface of the support plate.

[0008] As a further technical solution of this utility model, the output end of the punching machine body is connected to a mounting plate after passing through a circular hole and a support frame, and three punching posts are installed on the bottom surface of the mounting plate.

[0009] As a further technical solution of this utility model, each of the perforated posts is provided with an upper groove below it, and a lower groove is provided below the upper groove.

[0010] As a further technical solution of this utility model, the workbench has an internal slot, two fans are installed on the inner wall of the slot, and a through slot is provided on the bottom surface of the workbench.

[0011] As a further technical solution of this utility model, a vacuum head is connected to the outer surface of the through groove, a hose is connected to the input end of the vacuum head, and a vacuum bucket is connected to the end of the hose away from the vacuum head.

[0012] As a further technical solution of this utility model, a waste bin is provided below the lower trough, a finished product bin is provided below the workbench, and a controller is installed on the outer surface of the workbench.

[0013] This utility model provides a safety protection device for a pneumatic drilling machine, which has the following advantages compared with the prior art:

[0014] This design presents a safety protection device for a pneumatic punching machine. A sliding groove effectively limits the movement of thin metal sheets, resisting the upward warping force generated when the punching machine body presses down. This prevents the metal sheets from warping at the edges or bending and deforming due to their elasticity, thus ensuring the accuracy of the punching position. Through the coordinated action of the electric telescopic rod, connecting plate, push rod, and push bar, along with the sliding groove, rapid feeding of thin metal sheets is achieved, significantly reducing manual operation steps. This eliminates the need for operators to keep their hands away from the punch's working area, significantly reducing the risk of injury due to misoperation. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a safety protection device for a pneumatic drilling machine: it includes a workbench 1, with two sliding grooves 2 installed on the upper surface of the workbench 1. A placement frame 3 is installed on the upper surface of the two sliding grooves 2. A connecting groove 9 is opened on the bottom surface of the placement frame 3. Observation ports 4 are opened on the left and right sides of the placement frame 3. An electric telescopic rod 5 is installed on the outer surface of the placement frame 3. A connecting plate 6 is connected to the output end of the electric telescopic rod 5. Two push rods 7 are connected to the outer surface of the connecting plate 6. A push bar 8 is installed on the end of the two push rods 7 away from the connecting plate 6. The outer surface of the push bar 8 is slidably connected to the inside of the sliding groove 2. The placement frame 3 is used to stack metal sheets. After the push bar 8 pushes the metal sheets to the processing position, the electric telescopic rod 5 retracts and drives the push bar 8 to retract. Then, the unprocessed metal sheets on the upper layer will fall due to gravity.

[0023] like Figure 2 As shown, a support frame 10 is installed on the upper surface of the workbench 1. An infrared detection device 28 is installed on the inner wall of the support frame 10. Two support columns 11 are installed on the upper surface of the support frame 10. A support plate 12 is installed on the end of the two support columns 11 away from the support frame 10. After the receiver inside the infrared detection device 28 receives the reflected infrared signal, it will convert this light signal into an electrical signal and quickly transmit the electrical signal to the controller 27. After receiving the signal, the controller 27 will determine that the metal sheet has been accurately positioned and then immediately issue a command to control the drilling machine body 14 to start working, driving the drilling column 16 to move downward to perform the drilling operation.

[0024] like Figure 3As shown, a circular hole 13 is provided on the outer surface of the support plate 12, and a punching machine body 14 is installed on the upper surface of the support plate 12.

[0025] like Figure 3 As shown, the output end of the punching machine body 14 passes through the round hole 13 and the support frame 10 respectively and is connected to the mounting plate 15. Three punching posts 16 are installed on the bottom surface of the mounting plate 15. The output end of the punching machine body 14 has a certain length because it needs to drive the mounting plate 15 and the punching posts 16 to complete the downward punching action. The design of passing it through the support frame 10 can effectively prevent the output end from bending when subjected to force.

[0026] like Figure 5 As shown, each punching post 16 has an upper groove 17 below it, and a lower groove 20 below the upper groove 17. When the punching post 16 moves downward to punch the metal sheet, the upper groove 17 provides sufficient penetration space for the punching post 16, avoiding the situation where the punching post 16 cannot completely penetrate the metal sheet due to the presence of obstacles below, thus ensuring the thoroughness of the punching and ensuring that the punched hole meets the requirements.

[0027] like Figure 5 As shown, the workbench 1 has an internal slot 18, and two fans 19 are installed on the inner wall of the slot 18. The bottom surface of the workbench 1 has a through slot 21. The slot 18 is located inside the workbench 1 and is a key structure in the device used to accommodate and support the fans 19 and to provide a channel for the collection of metal scraps.

[0028] like Figure 3 As shown, a vacuum head 22 is connected to the outer surface of the through groove 21. The input end of the vacuum head 22 is connected to a hose 23. The end of the hose 23 away from the vacuum head 22 is connected to a dust collection bin 24. The vacuum head 22 is connected to the outer surface of the through groove 21 on the bottom of the workbench 1 and is an important link in the metal scrap collection path. Its operation is coordinated with the fan 19 and the dust collection bin 24. Under the propulsion of the airflow, the metal scrap is transported to the dust collection bin 24 through the hose 23 connected to the input end of the vacuum head 22, thereby completing the collection of metal scrap.

[0029] like Figure 3 As shown, a waste bin 25 is provided below the lower trough 20, a finished product bin 26 is provided below the workbench 1, and a controller 27 is installed on the outer surface of the workbench 1.

[0030] The working principle of this utility model is as follows: First, the operator places the metal sheet in the placement frame 3. After the device is started by the controller 27, the electric telescopic rod 5 is immediately activated. Its output end drives the connecting plate 6 to move synchronously. The connecting plate 6 then pushes the two push rods 7, causing the push bar 8 to slide smoothly in the sliding groove 2, thereby pushing the metal sheet to move precisely to the drilling position to achieve material feeding. When the metal sheet is pushed to the preset drilling position, the infrared detection device 28 quickly detects that the material is in place and then transmits the signal to the controller 27. The controller 27 immediately instructs the drilling machine body 14 to start working. The output end of the drilling machine body 14 passes through the round hole 13 on the support plate 12 and the support frame 10 in sequence, driving the mounting plate 15 and the three drilling columns 16 on the bottom surface to move downwards, accurately completing the drilling of the metal sheet. During the drilling operation, the blocky waste generated will fall into the lower groove 20 through the upper groove 17 below the drilling column 16, and finally fall smoothly into the waste bin 25 for centralized collection. At the same time, the two fans 19 in the empty groove 18 inside the workbench 1 start synchronously, efficiently blowing the metal debris generated by drilling into the through groove 21. The debris enters the hose 23 through the dust suction head 22 on the outer surface of the through groove 21 and is quickly transported to the dust collection bin 24 for unified collection. After the drilling is completed, the push bar 8 continues to push the subsequent unprocessed metal sheet. Through the pushing force of the unprocessed metal sheet, the processed metal sheet is smoothly pushed into the finished product box 26 below the workbench 1, thus completing the entire drilling process. During this process, the observation ports 4 on the left and right sides of the placement frame 3 allow the operator to observe the processing status in real time.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
