Description

Technical Field

[0001] This utility model relates to the technical field of machining equipment, specifically a precision metal drilling machine. Background Technology

[0002] A precision drilling machine is a precision machine tool used for metal processing. It is mainly used for drilling, reaming, boring, countersinking, tapping and other processing operations. This machine tool is characterized by high precision, high efficiency and high automation, and is widely used in industries such as aviation, aerospace, military, automobile, motorcycle, electronics, communications and instrumentation.

[0003] During machining, metal drilling machines typically use fixtures to hold workpieces, making it difficult to flip and fully clamp them, which limits their practicality. Furthermore, when flipping workpieces, a certain amount of space needs to be left for rotation. If the workpiece is flipped directly, problems such as structural jamming and machine jamming may occur. Therefore, we designed a precision metal drilling machine. Utility Model Content

[0004] The purpose of this utility model is to provide a precision metal drilling machine that can flip the workpiece to achieve full drilling without jamming, thus solving the problems in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A precision machining drilling machine for hardware includes a base bed, a lifting platform is provided on the rear side of the base bed, a cross slide is fixedly installed on the lower surface of the lifting platform, an mounting plate is fixedly connected to the lower surface of the slider inside the cross slide, a drive motor is fixedly installed on the lower surface of the mounting plate, and a drill bit is fixedly connected to the output end of the drive motor through a coupling. Electric slide rails are fixedly installed on both the left and right sides of the upper surface of the base bed, a support plate is fixedly connected to the upper surface of the slider inside the electric slide rail, a servo motor is fixedly installed on the side of the support plate, and a clamp is fixedly connected to the output end of the servo motor through the support plate through a coupling.

[0006] The upper surface of the placement base bed is provided with a movable groove, and a placement frame is slidably connected in the movable groove. An electric push rod is fixedly installed on the inner bottom wall of the movable groove, and the output end of the electric push rod is fixedly connected to the bottom wall of the placement frame. A movable through hole is provided on the upper surface of the placement frame. A servo motor is fixedly installed on the inner wall of the placement frame. The output end of the servo motor is fixedly connected to a threaded rod through a coupling, and the other end of the threaded rod is movably connected to the inner wall of the placement frame. A movable block is movably connected to the outer side of the threaded rod. A T-shaped plate is fixedly connected to the upper surface of the movable block, and the T-shaped plate passes through the movable through hole. A dustproof component is also provided on the placement frame.

[0007] Through the above technical solution, the placement frame of this application can provide a stable foundation to ensure processing accuracy. On the other hand, the downward movement of the placement frame can provide enough space for the workpiece to be flipped normally. That is, under the premise of ensuring stable processing of the workpiece, the workpiece can be flipped for full processing without affecting the normal operation of the equipment.

[0008] Preferably, the number of the moving blocks is two and they are distributed front to back on the threaded rod, and the thread direction of the first half of the threaded rod is opposite to that of the second half.

[0009] Through the above technical solution, the rotation of the threaded rod of this application will drive the two moving blocks to move relative to each other, that is, the two T-plates move relative to each other to clamp and unload the workpiece.

[0010] Preferably, the dustproof component includes: a strip groove, a baffle, and a shovel. The inner wall of the movable through hole is provided with a strip groove, a baffle is inserted into the strip groove, and the side of the baffle away from the strip groove is fixedly connected to a T-shaped plate. The inner wall of the movable through hole is also fixedly connected with a shovel.

[0011] Through the above technical solution, the dustproof component of this application can prevent the debris generated during processing from falling into the placement frame and affecting the internal structure, thereby ensuring processing accuracy and stability.

[0012] Preferably, the shovel is located above and in contact with the baffle, and the top of the shovel is designed to be inclined.

[0013] Through the above technical solution, the shovel plate of this application can scoop up the debris on the baffle, so that the baffle will not be affected by the debris when it moves.

[0014] Preferably, a water pump and an air pump are fixedly installed on the lower surface of the mounting plate and on the left and right sides of the drive motor, respectively.

[0015] Through the above technical solutions, the water pump and air pump of this application play the role of spraying water for cooling and cleaning debris during drill bit processing.

[0016] Preferably, the top of the T-shaped plate extends above the placement base bed and contacts the placement base bed, and anti-slip pads are adhered to the sides of the T-shaped plate and the sides of the clamp.

[0017] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0018] 1. This precision machining drilling machine can flip the clamped workpiece to achieve full drilling. The design of the placement frame not only provides a solid support for the workpiece during drilling, but also allows it to move downwards to provide sufficient space for flipping the workpiece. After flipping, the workpiece is reset to provide a foundation, ensuring that the workpiece remains stable during drilling and solving the problems mentioned in the background technology.

[0019] 2. This precision machining drilling machine features a dustproof component design that allows the baffle to move along with the moving block. This design, where the workpiece covers the moving through hole and the baffle covers the moving through hole, prevents machining debris from falling into the placement frame and affecting the normal operation of the equipment.

[0024] 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.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a precision machining drilling machine for hardware, including a base bed 1, a lifting platform 2 provided on the rear side of the base bed 1, a cross slide 3 fixedly installed on the lower surface of the lifting platform 2, an mounting plate 4 fixedly connected to the lower surface of the slider inside the cross slide 3, a drive motor 5 fixedly installed on the lower surface of the mounting plate 4, and a drill bit 6 fixedly connected to the output end of the drive motor 5 through a coupling. Electric slide rails 7 are fixedly installed on both the left and right sides of the upper surface of the base bed 1, a support plate 8 fixedly connected to the upper surface of the slider inside the electric slide rail 7, a servo motor 9 fixedly installed on the side of the support plate 8, and a clamp 10 fixedly connected to the output end of the servo motor 9 through the support plate 8 through a coupling.

[0026] A movable groove 11 is provided on the upper surface of the placement base bed 1. A placement frame 12 is slidably connected in the movable groove 11. An electric push rod 13 is fixedly installed on the inner bottom wall of the movable groove 11, and the output end of the electric push rod 13 is fixedly connected to the bottom wall of the placement frame 12. A movable through hole 14 is provided on the upper surface of the placement frame 12. A servo motor 15 is fixedly installed on the inner wall of the placement frame 12. A threaded rod 16 is fixedly connected to the output end of the servo motor 15 through a coupling 3, and the other end of the threaded rod 16 is movably connected to the inner wall of the placement frame 12. A movable block 17 is movably connected to the outer side of the threaded rod 16. A T-shaped plate 18 is fixedly connected to the upper surface of the movable block 17, and the T-shaped plate 18 passes through the movable through hole 14. A dustproof component 19 is also provided on the placement frame 12.

[0027] Through the above technical solution, the placement frame 12 of this application can provide a stable foundation to ensure processing accuracy. On the other hand, the downward movement of the placement frame 12 can provide enough space for the workpiece to be flipped normally. That is, under the premise of ensuring stable processing of the workpiece, the workpiece can be flipped for full processing without affecting the normal operation of the equipment.

[0028] There are two movable blocks 17, which are distributed in a front-to-back manner on the threaded rod 16. The thread direction of the first half of the threaded rod 16 is opposite to that of the second half.

[0029] Through the above technical solution, the rotation of the threaded rod 16 of this application will drive the two moving blocks 17 to move relative to each other, that is, the two T-shaped plates 18 move relative to each other to clamp and unload the workpiece.

[0030] The dustproof component 19 includes: a strip groove 191, a baffle 192, and a scraper 193. The inner wall of the movable through hole 14 is provided with a strip groove 191, and a baffle 192 is inserted into the strip groove 191. The side of the baffle 192 away from the strip groove 191 is fixedly connected to the T-shaped plate 18. The inner wall of the movable through hole 14 is also fixedly connected with a scraper 193.

[0031] Through the above technical solution, the dustproof component 19 of this application can prevent the debris generated during processing from falling into the placement frame 12 and affecting the internal structure, thereby ensuring processing accuracy and stability.

[0032] The shovel plate 193 is located above and in contact with the baffle plate 192, and the top of the shovel plate 193 is designed to be inclined.

[0033] Through the above technical solution, the shovel plate 193 of this application can scoop up the debris on the baffle 192, so that the baffle 192 will not be affected by the debris when it moves.

[0034] A water pump 20 and an air pump 21 are fixedly installed on the lower surface of the mounting plate 4 and on the left and right sides of the drive motor 5, respectively.

[0035] Through the above technical solution, the water pump 20 and air pump 21 of this application play the role of spraying water for cooling and cleaning debris during the machining of the drill bit 6.

[0036] The top of the T-shaped plate 18 extends above and contacts the placement base bed 1. Anti-slip pads are glued to the sides of the T-shaped plate 18 and the sides of the clamp 10.

[0037] When this precision machining drilling machine is in operation, the workpiece to be processed is placed on the placement frame 12. At this time, the workpiece covers part of the movable through hole 14. The servo motor 15 is started to drive the threaded rod 16 to rotate. The two T-plates 18 move relative to each other to limit the workpiece. At the same time, the movement of the T-plates 18 will drive the baffle 192 to move and completely block the movable through hole 14, thereby preventing debris from falling into the placement frame 12 and causing damage. Then, the electric slide rail 7 is started to clamp the workpiece with the fixture 10 for limiting. The lifting platform 2, the cross slide 3 and the drive motor are used to achieve the same result. The cooperation of 5 allows the drill bit 6 to move up and down, left and right, and forward and backward to drill one side of the workpiece. After the workpiece is processed on one side, the servo motor 15 reverses to detach the T-shaped plate 18 from the workpiece. The electric push rod 13 is activated to shorten and drive the placement frame 12 to move downward. At this time, the two clamps 10 hold the workpiece and the servo motor 9 is activated to drive the workpiece to rotate and flip. Then the electric push rod 13 extends and resets to make the placement frame 12 fit tightly against the lower surface of the workpiece to provide support. The drilling process on the other side is then carried out by the drill bit 6 to complete the full processing.
