Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically a drilling device capable of double-sided processing. Background Technology

[0002] In modern industrial production and infrastructure construction, drilling is a fundamental and crucial process. During the production and processing of sheet metal, drilling is necessary to facilitate later use. However, existing sheet metal drilling devices still have certain shortcomings, such as: The patent application CN202322635229.X, entitled "A Steel Plate Drilling Device for Shipbuilding Industry," can only perform single-sided processing. In actual production, when it is necessary to drill non-through blind holes on both sides of the plate, the plate needs to be flipped over, which is time-consuming and labor-intensive and affects the plate processing efficiency. Therefore, a drilling device capable of double-sided processing is proposed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a drilling device capable of double-sided processing, in order to solve the problem mentioned in the background art that existing plate drilling devices can only process on one side and are inconvenient for processing blind holes on both sides.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a drilling device capable of double-sided processing, comprising a base plate and a drill bit; A support frame is fixedly installed on the top surface of the base plate, and multiple support rollers are provided inside the support frame. A fixing frame is fixedly installed on the top surface of the base plate, and the fixing frame is sleeved on the outside of the support frame. Telescopic cylinders are fixedly installed on both the top and bottom sides inside the fixing frame, and a housing is fixedly installed on the output end of the telescopic cylinder. A rotating rod is longitudinally arranged through the side of the housing away from the telescopic cylinder, and the rotating rod is connected to the housing through a bearing. The end of the rotating rod away from the telescopic cylinder is coaxially fixedly connected to the drill bit.

[0005] The above technical solution facilitates double-sided drilling of sheet materials, allowing for the completion of double-sided blind hole processing without flipping the sheet, significantly shortening the processing flow and improving overall processing efficiency.

[0006] As a preferred embodiment of this utility model, an electric telescopic rod is fixedly installed on the top surface of the fixed frame, and a lifting frame is fixedly installed at the output end of the electric telescopic rod. The lifting frame slides longitudinally through the top of the fixed frame, and a pressure frame is fixedly installed on the bottom surface of the lifting frame.

[0007] The above technical solution facilitates the use of an electric telescopic rod to drive the lifting frame to move the pressure frame up and down, quickly pressing or releasing the board material, ensuring the stability of the board material position during the drilling process, and avoiding displacement that could affect the drilling accuracy.

[0008] As a preferred technical solution of this utility model, a motor is fixedly installed on the inner wall of the machine box near the telescopic cylinder, and the output end of the motor is coaxially and fixedly connected to the end of the rotating rod near the telescopic cylinder, and the rotating rod is coaxially and fixedly connected to the drill bit.

[0009] By adopting the above technical solution, the motor output torque can be directly transmitted to the rotating rod, driving the drill bit to rotate at high speed and providing stable power for drilling operations.

[0010] As a preferred technical solution of this utility model, a rubber anti-slip pad is fixedly installed on the bottom surface of the pressure frame.

[0011] By adopting the above technical solution, the friction between the pressure frame and the plate can be increased, further improving the fixing effect, while avoiding hard contact between the pressure frame and the plate surface, thus protecting the appearance of the workpiece.

[0012] As a preferred technical solution of this utility model, the rotating rod and the drill bit are detachably connected by a disassembly and assembly mechanism. The disassembly and assembly mechanism includes a connecting seat, which is coaxially fixedly installed at the end of the rotating rod away from the telescopic cylinder. The bottom of the connecting seat is open. A connecting frame is movably inserted into the connecting seat and is fixedly connected to the drill bit. The connecting frame has a U-shaped structure. A bidirectional threaded rod is installed on the left inner wall of the connecting seat through a bearing, and the bidirectional threaded rod passes through the right side wall of the connecting seat through a bearing. Two sliding plates are symmetrically sleeved on the outer side of the bidirectional threaded rod, and the bidirectional threaded rod is threadedly connected to the sliding plates. The sliding plates are laterally slidably connected to the inner wall of the connecting seat, and a locking block is fixedly installed at the end of the sliding plate. The locking block is movably inserted into a slot opened on the side wall of the connecting frame.

[0013] The above technical solution facilitates the insertion and removal of the locking block and the locking slot by rotating the bidirectional threaded rod, enabling quick installation and removal of the drill bit, adapting to different hole diameter processing needs, and improving the flexibility of use.

[0014] As a preferred embodiment of this utility model, limit blocks are fixedly installed on both the left and right inner walls of the connecting seat.

[0015] The above technical solution facilitates the limitation of the position of the connecting bracket extending into the connecting seat, ensuring stable and effective insertion of the card block and the card slot.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the double-sided drilling device can realize double-sided processing of the board without the need for flipping, which greatly saves processing time and improves processing efficiency; at the same time, the electric telescopic rod drives the pressure frame to fix the board with rubber anti-slip pads, ensuring the stability of the board during the drilling process and improving processing accuracy. 1. By simultaneously setting telescopic cylinders, machine housing and drill bits on the top and bottom sides of the fixed frame, double-sided drilling of sheet metal can be achieved. Double-sided blind hole processing can be completed without flipping the sheet metal, which greatly reduces the process flow time and manual intervention steps. It effectively solves the problem of time-consuming and labor-intensive processing of double-sided workpieces by traditional single-sided drilling devices, and significantly improves the overall processing efficiency. It is especially suitable for mass production scenarios. 2. With the help of the electric telescopic rod driven pressure frame and the rubber anti-slip pad on the bottom, the plate can be pressed quickly and firmly, avoiding problems such as hole diameter deviation and hole position displacement caused by workpiece displacement during the drilling process; at the same time, the design of the rubber anti-slip pad can avoid hard contact between the pressure frame and the surface of the plate, reducing scratches or damage to the workpiece surface, protecting the integrity of the workpiece appearance while ensuring processing quality, and improving the finished product qualification rate. 3. The rotating rod and the drill bit are detachably connected through a disassembly and assembly mechanism. Simply rotate the bidirectional threaded rod to control the insertion and removal of the locking block and the slot, and quickly complete the replacement of the drill bit. This design allows the device to flexibly adapt to drilling needs of different hole diameters and specifications, improving the flexibility of use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0020] Example 1 Please see Figure 1 - Figure 3 The present invention provides a drilling device capable of double-sided processing, comprising a base plate 1 and a drill bit 8. A controller for controlling various electrical devices is provided on the base plate 1. A support frame 2 is fixedly installed on the top surface of the base plate 1, and multiple support rollers 3 are provided inside the support frame 2. A fixing frame 4 is fixedly installed on the top surface of the base plate 1, and the fixing frame 4 is sleeved on the outside of the support frame 2. Telescopic cylinders 5 are fixedly installed on both the top and bottom surfaces inside the fixing frame 4, and a housing 6 is fixedly installed at the output end of the telescopic cylinder 5. A rotating rod 7 is longitudinally arranged through the side of the housing 6 away from the telescopic cylinder 5, and the rotating rod 7 is connected to the housing 6 through a bearing. The end of the rotating rod 7 away from the telescopic cylinder 5 is connected to the drill bit 8.

[0021] An electric telescopic rod 10 is fixedly installed on the top surface of the fixed frame 4, and a lifting frame 11 is fixedly installed at the output end of the electric telescopic rod 10. The lifting frame 11 slides longitudinally through the top of the fixed frame 4, and a pressure frame 12 is fixedly installed on the bottom surface of the lifting frame 11. A rubber anti-slip pad 13 is fixedly installed on the bottom surface of the pressure frame 12.

[0022] A motor 9 is fixedly installed on the inner wall of the casing 6 near the telescopic cylinder 5, and the output end of the motor 9 is coaxially and fixedly connected to the end of the rotating rod 7 near the telescopic cylinder 5. The rotating rod 7 is also coaxially and fixedly connected to the drill bit 8.

[0023] Working principle: When in use, the material to be processed is placed on the support roller 3 of the support frame 2, and the material is adjusted to the target drilling position by the rolling of the support roller 3; Start the electric telescopic rod 10, which drives the lifting frame 11 to move downward, causing the pressure frame 12 to descend synchronously until the rubber anti-slip pad 13 on the bottom of the pressure frame 12 is tightly attached to the surface of the board, thus achieving a stable fixation of the board. When coaxial blind holes need to be drilled on both sides of the board, the motors 9 on the top and bottom sides of the fixed frame 4 are started. The output torque of the motors 9 is transmitted to the rotating rod 7, which drives the drill bit 8 to rotate at high speed. Then, the telescopic cylinder 5 is extended to push the machine box 6 and the rotating drill bit 8 to move towards the board. The drill bits 8 on the top and bottom sides of the board perform synchronous drilling operations on the top and bottom sides of the board respectively. After the drilling is completed, the telescopic cylinder 5 retracts to drive the drill bit 8 to reset. The electric telescopic rod 10 retracts to drive the pressure frame 12 to rise and release the board. Finally, the processed board is removed by the support roller 3, completing one double-sided drilling process. When drilling blind holes or through holes on one side, drilling on one side can be completed by activating only one side of the motor 9 and telescopic cylinder 5.

[0024] Example 2 Specifically, such as Figure 4 - Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the rotating rod 7 and the drill bit 8 are detachably connected through a disassembly and assembly mechanism. The disassembly and assembly mechanism includes a connecting seat 14, which is coaxially fixedly installed at the end of the rotating rod 7 away from the telescopic cylinder 5. The bottom of the connecting seat 14 is open. A connecting frame 15 is movably inserted into the inside of the connecting seat 14 and is fixedly connected to the drill bit 8. The connecting frame 15 has a U-shaped structure. A bidirectional threaded rod 16 is installed on the left inner wall of the connecting seat 14 through a bearing. The bidirectional threaded rod 16 passes through the right side wall of the connecting seat 14 through a bearing. Two sliding plates 17 are symmetrically sleeved on the outside of the bidirectional threaded rod 16 and are threadedly connected to the sliding plates 17. The sliding plates 17 are laterally slidably connected to the inner wall of the connecting seat 14. A locking block 18 is fixedly installed at the end of the sliding plate 17. The locking block 18 is movably inserted into the slot 19 opened on the side wall of the connecting frame 15. Limiting blocks 20 are fixedly installed on both the left and right inner walls of the connecting seat 14.

[0025] With the above structural design, the appropriate drill bit 8 can be replaced according to the required hole diameter. By rotating the bidirectional threaded rod 16, the sliding plates 17 on both sides are slid inward, causing the locking block 18 to disengage from the slot 19 of the connecting frame 15. The connecting frame 15 with the old drill bit 8 can then be removed from the bottom opening of the connecting seat 14. The connecting frame 15 with the new drill bit 8 is then inserted into the connecting seat 14 until the connecting frame 15 contacts the limiting block 20. The bidirectional threaded rod 16 is then rotated in the opposite direction, causing the sliding plate 17 to slide outward, so that the locking block 18 is inserted into the slot 19 of the connecting frame 15, thus completing the fixed installation of the drill bit 8 and enabling the replacement of drill bits 8 with different diameters to drill holes of different diameters.
