Description

Technical Field

[0001] This utility model relates to the field of aluminum sheet processing technology, specifically to a positioning drilling machine for aluminum sheet processing. Background Technology

[0002] Aluminum sheets have a wide range of applications. They are used in the production and manufacturing of walls, bags, furniture, cabinets, appliances, glass, and car decorations that we often see in our daily lives. At the same time, aluminum sheets are also frequently used in aerospace, military, and mechanical parts processing. It can be said that life is inseparable from aluminum sheets. In some application scenarios, it is necessary to drill holes in aluminum sheets, so aluminum sheet drilling machines have been developed.

[0003] In order to ensure the accuracy of drilling, some traditional aluminum sheet drilling machines generally require workers to manually straighten the aluminum sheet, place it under the drill bit, and then position the aluminum sheet to ensure the accuracy of the drilling position before starting to drill the aluminum sheet.

[0004] There are some problems, such as the need for workers to frequently straighten and position the aluminum sheets when drilling increases, which increases labor costs and makes the operation more cumbersome. To address this, we propose a positioning drilling machine for aluminum sheet processing. Utility Model Content

It is simple and labor-saving to operate, and does not require too much manual operation by workers. It greatly reduces the difficulty of workers manually straightening and positioning aluminum plates and increases the work efficiency of drilling holes in aluminum plates.

[0010] Furthermore, the positioning and straightening mechanism also includes a push rod, which is fixedly connected to the right end of the front side of the straightening clamp, facilitating the driving of the straightening mechanism.

[0011] Furthermore, the front end of the bracket is provided with a control switch group, the input end of which is electrically connected to an external power source for stable driving.

The output shaft of the motor is fixedly connected to the upper end face of the drill bit. The input ends of the electric telescopic rod 2 and the motor are both electrically connected to the output end of the control switch group, which facilitates drilling holes in the aluminum plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This embodiment provides a technical solution: a positioning drilling machine for aluminum plate processing.

[0025] Includes bracket 1, positioning and clamping mechanism 2, and positioning and straightening mechanism 3;

[0026] Support 1: A drilling support 8 is placed behind it. A sliding plate 7 is slidably connected to the upper end of the drilling support 8. A drill bit 10 is rotatably connected to the front end of the sliding plate 7. A control switch group 5 is provided at the front end of the support 1. The input end of the control switch group 5 is electrically connected to an external power source. An electric telescopic rod 9 is bolted to the rear side of the drilling support 8. The telescopic end of the electric telescopic rod 9 is fixedly connected to the lower rear end of the sliding plate 7. A motor 6 is bolted to the upper side of the sliding plate 7. The output shaft of the motor 6 is fixedly connected to the upper end face of the drill bit 10. The input ends of the electric telescopic rod 9 and the motor 6 are both electrically connected to the output end of the control switch group 5. An electric conveyor belt 4 is installed between the front and rear ends of the upper end of the support 1. The input of the electric conveyor belt 4 is... The end is electrically connected to the output end of the control switch group 5. When the worker needs to drill a hole in the aluminum plate, the worker first needs to use the control switch group 5 to make the electric conveyor belt 4 run. Then the worker places the aluminum plate to be drilled on the electric conveyor belt 4. At this time, the aluminum plate begins to move to the left under the operation of the electric conveyor belt 4 to facilitate the transfer of the aluminum plate to be drilled. The worker uses the control switch group 5 to drive the motor 6. The output end of the motor 6 drives the drill bit 10 to rotate. Then the worker uses the control switch group 5 to make the electric telescopic rod 9 run. At this time, the telescopic end of the electric telescopic rod 9 pulls the sliding plate 7 to slide down along the upper end of the drilling bracket 8, thereby driving the rotating drill bit 10 to move down until it contacts the aluminum plate to complete the drilling work.

[0027] Positioning and straightening mechanism 3: It includes a straightening frame 31, a rotating shaft 32, a straightening clamping plate 33, a sliding column 34, a connecting rod 35, a pin 36, and a connecting rotating plate 38. The straightening frame 31 is located on the upper right side of the support 1. A sliding column 34 is provided between the front and rear inner walls of the straightening frame 31. The straightening clamping plate 33 is slidably connected to both ends of the sliding column 34. The connecting rotating plate 38 is rotatably connected to the middle of the top wall of the straightening frame 31 through the rotating shaft 32. The left and right ends of the lower side of the connecting rotating plate 38 are rotatably connected to the connecting rod 35 through the rotating shaft. 5. Each of the straightening clamps 33 has a pin 36 at its upper end. The outer ends of the two connecting rods 35 are rotatably connected to the upper ends of the adjacent pins 36. The positioning and straightening mechanism 3 also includes a push rod 37, which is fixedly connected to the right end of the front side of the straightening clamp 33. When the aluminum plate moves to the positioning and straightening mechanism 3, the worker pushes the push rod 37 backward. Under the pushing force of the push rod 37, the front straightening clamp 33 and the front pin 36 move backward simultaneously. At this time, the front pin 36 pushes the front... When connecting rod 35 moves backward, it simultaneously pushes the rotating shaft on the right side of connecting plate 38. After receiving this thrust, connecting plate 38 begins to rotate around shaft 32. During this rotation, the left end of connecting plate 38 pulls the rear connecting rod 35 via the rotating shaft. The rear connecting rod 35 then pulls the rear straightening clamp 33 via the rear pin 36, causing both straightening clamps 33 to move inward simultaneously (during this process, the end of connecting rod 35 connected to the rotating shaft remains stationary). As the rotating clamping plate 33 slides on the outer arc surface of the sliding column 34, the two clamping plates 33 gradually come into contact with the aluminum plate. As the two clamping plates 33 continue to move inward, they gradually begin to squeeze the aluminum plate. At this moment, the aluminum plate is squeezed by the two clamping plates 33, and the side of the aluminum plate that contacts the clamping plate 33 contacts and is parallel to the inner side of the clamping plate 33. At this time, the aluminum plate is straightened by the guidance of the two clamping plates 33, thus performing preliminary positioning of the aluminum plate to facilitate subsequent final positioning.

[0028] Positioning and clamping mechanism 2: It is located on the upper end of the bracket 1, to the left of the positioning and straightening mechanism 3. The positioning and clamping mechanism 2 includes a second mounting plate 24, an electric cylinder 25, a slide rail 26, and a positioning slider 27. The second mounting plate 24 is located on the rear side of the bracket 1. The upper side of the second mounting plate 24 is provided with a slide rail 26. The upper end of the slide rail 26 is slidably connected to the positioning slider 27. The upper side of the second mounting plate 24 is equipped with an electric cylinder 25 via an electric cylinder bracket. The telescopic end of the electric cylinder 25 is fixedly connected to the left end of the positioning slider 27. The input end of the electric cylinder 25 is electrically connected to the output end of the control switch group 5. The clamping mechanism 2 also includes a first mounting plate 21, an electric telescopic rod 22, and a diagonal positioning block 23. The first mounting plate 21 is located on the front side of the bracket 1. The upper end of the first mounting plate 21 is equipped with an electric telescopic rod 23 via a mounting bracket. 2. A diagonal positioning block 23 is installed at the telescopic end of the electric telescopic rod 22. The upper side of the diagonal positioning block 23 has a right-angle groove. The input end of the electric telescopic rod 22 is electrically connected to the output end of the control switch group 5. Then, the worker drives the electric cylinder 25 through the control switch group 5. At this time, the telescopic end of the electric cylinder 25 pushes the positioning slider 27 to move forward along the track of the slide rail 26. When the leftmost edge of the aluminum plate contacts the left side of the positioning slider 27, the worker drives the electric telescopic rod 22 through the control switch group 5. The telescopic end of the electric telescopic rod 22 pushes the diagonal positioning block 23 to move to the left and rear. The right-angle groove of the diagonal positioning block 23 gradually contacts the angle formed by the front side and the right side of the aluminum plate and pushes the aluminum plate. At this time, the positioning and clamping work of the aluminum plate is completed with the cooperation of the positioning slider 27 and the diagonal positioning block 23.

[0029] The working principle of the positioning drilling machine for aluminum plate processing provided by this utility model is as follows: When the worker needs to drill holes in the aluminum plate, the worker first needs to control the switch group 5 to make the electric conveyor belt 4 run. Then, the worker places the aluminum plate to be drilled on the electric conveyor belt 4. At this time, the aluminum plate begins to move to the left under the operation of the electric conveyor belt 4. When the aluminum plate moves to the positioning and straightening mechanism 3, the worker pushes the push rod 37 backward. Under the pushing force of the push rod 37, the front straightening clamp 33 and the front pin 36 move backward at the same time. At this time, the front pin 36 pushes the front connecting rod 35 to move backward. At the same time, the connecting rod 35 pushes the connecting rotating plate 3. The rotating shaft on the right side of the 8-axis, after the connecting plate 38 is pushed, begins to rotate around the rotating shaft 32. During the rotation of the connecting plate 38, the left end of the connecting plate 38 pulls the rear connecting rod 35 through the rotating shaft. The rear connecting rod 35 pulls the rear straightening clamp 33 through the rear pin 36, so that the two straightening clamps 33 move inward at the same time. The two straightening clamps 33 gradually contact the aluminum plate. As the two straightening clamps 33 continue to move inward (during this process, the end of the connecting rod 35 connected to the rotating shaft always keeps rotating, and the straightening clamp 33 always slides on the outer arc surface of the sliding column 34), they gradually begin to squeeze the aluminum plate. At this moment, the aluminum plate passes through the two The aluminum sheet is pressed by the straightening clamp 33, and the side of the aluminum sheet that contacts the straightening clamp 33 is in contact with and parallel to the inner side of the straightening clamp 33. At this time, guided by the two straightening clamps 33, the aluminum sheet is straightened, thus performing preliminary positioning of the aluminum sheet to facilitate subsequent final positioning. Then, the worker controls the switch group 5 to drive the electric cylinder 25. At this time, the telescopic end of the electric cylinder 25 pushes the positioning slider 27 forward along the track of the slide rail 26. When the leftmost edge of the aluminum sheet contacts the left side of the positioning slider 27, the worker controls the switch group 5 to activate the electric telescopic rod 22. The telescopic end of the electric telescopic rod 22 pushes the diagonal positioning block 23 to move to the left and rear. The right-angle groove of the diagonal positioning block 23 gradually contacts the angle formed by the front and right sides of the aluminum plate and pushes the aluminum plate. At this time, the positioning slider 27 and the diagonal positioning block 23 cooperate to complete the positioning and clamping of the aluminum plate, which makes it easier for the worker to drill the aluminum plate. At this time, the worker drives the motor 6 by controlling the switch group 5. The output end of the motor 6 drives the drill bit 10 to rotate. Then, the worker controls the switch group 5 to make the electric telescopic rod 9 rotate. At this time, the telescopic end of the electric telescopic rod 9 pulls the sliding plate 7 to slide down along the upper end of the drilling bracket 8, thereby driving the rotating drill bit 10 to move down until it contacts the aluminum plate to complete the drilling work.

[0030] It is worth noting that the electric conveyor belt 4 disclosed in the above embodiments can be model CB-01, the motor 6 can be model Y90L-2, the electric telescopic rod 29 and the electric telescopic rod 22 can both be model FY015, the electric cylinder 25 can be model YRJ045, and the control switch group 5 is provided with control buttons that correspond one-to-one with the electric conveyor belt 4, the motor 6, the electric telescopic rod 29, the electric telescopic rod 22 and the electric cylinder 25 and are used to control their switching.
