Description

Technical Field

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

[0002] Sheet metal processing is a comprehensive cold-working process involving thin metal sheets, encompassing various steps such as shearing, punching, cutting, compounding, bending, welding, riveting, splicing, and forming. Sheet metal parts obtained through this process are characterized by their light weight, high strength, good electrical and thermal conductivity, low cost, and suitability for mass production. Therefore, they are widely used in automotive manufacturing, electronics, communication equipment, medical devices, aerospace, and other fields. In practical applications, sheet metal parts are particularly common; these parts typically require drilling to meet subsequent assembly requirements.

[0003] In the drilling process of sheet metal parts, a storage structure is typically needed for temporary storage and transport. A common practice is to use a pair of opposing storage plates to create a space for placing the sheet metal parts. However, currently, the spacing between these storage plates is often fixed. In practice, if the sheet metal part shifts in center or tilts at the edges during placement, it is prone to friction with the inner wall of the storage plate, leading to jamming. This requires manual intervention for adjustment, increasing the workload and severely impacting the efficiency of sheet metal part placement.

[0004] Therefore, there is a need for a drilling device that can effectively ensure the positioning accuracy of sheet metal parts. Utility Model Content

[0029] Example 1

[0030] To ensure accurate placement and convenient processing of sheet metal workpieces, a sheet metal drilling machine was designed, the specific scheme of which is as follows:

[0031] like Figure 1-6 As shown, a sheet metal drilling machine includes a base 1, a mounting seat 2 mounted on the base 1, two storage plates 6 slidably connected to the mounting seat 2, an expansion structure 3 on the mounting seat 2, the expansion structure 3 including a guide frame 301, the guide frame 301 fixedly connected to the mounting seat 2, a guide block 302 fixedly connected to the storage plate 6, the guide block 302 slidably connected to the guide frame 301, a mounting shaft 303 fixedly connected to the guide frame 301, a turntable 304 rotatably connected to the mounting shaft 303, a cam groove 305 on the turntable 304, and a drive shaft 306 rotatably connected to the guide block 302, the drive shaft 306 rollingly engaging with the cam groove 305.

[0032] The turntable 304 is fixed by a limiting structure 4, which includes a fixing post 401. The fixing post 401 is fixedly connected to the turntable 304 and is rotatably connected to the mounting shaft 303. Pulling the connecting plate 402 on the fixing post 401 causes the limiting block 403 on the connecting plate 402 to no longer engage with the limiting groove 404 of the mounting shaft 303. At the same time, the spring 406 contracts, and then the turntable 304 on the mounting shaft 303 is rotated through the connecting plate 402. The cam groove 305 on the turntable 304 will form a rolling engagement with the drive shaft 306 on the guide block 302, causing the guide block 302 to slide smoothly along the guide frame 301, thereby causing the two storage plates 6 to move away synchronously. The sheet metal part is placed between the two storage plates 6, and the turntable... The rotation of 304 and cam groove 305 adjusts the spacing, preventing the sheet metal parts from getting stuck due to a fixed spacing and ensuring that the sheet metal parts can slide smoothly. A connecting plate 402 is slidably connected to the fixed column 401, and a limit block 403 is fixedly connected to the connecting plate 402. A limit groove 404 is provided on the mounting shaft 303. When the connecting plate 402 is loosened, the limit block 403 engages with the mounting shaft 303. The engagement of the limit block 403 with the mounting shaft 303 achieves reliable positioning of the turntable 304, preventing the spacing of the storage plate 6 from shifting during processing and ensuring feeding stability. The limit block 403 engages with the limit groove 404. A mounting plate 405 is fixedly connected to the fixed column 401, and a spring 406 is fixedly connected between the mounting plate 405 and the connecting plate 402.

[0033] The mounting base 2 is provided with an adjustment structure 5, which includes an adjustment plate 501. Two adjustment plates 501 are slidably connected to the mounting base 2, and a slider 502 is fixedly connected between the two adjustment plates 501. First, according to the thickness of the sheet metal part to be processed, the screw 503 on the mounting base 2 is rotated by the fixed block on the screw 503. The slider 502, which is threadedly connected to the screw 503, drives the two adjustment plates 501 to slide synchronously, thereby quickly adjusting the position of the two adjustment plates 501. The position of the adjustment plates 501 can be adjusted by the screw 503 to adapt to sheet metal parts of different thicknesses. The slider 502 is slidably connected to the mounting base 2, and the screw 503 is rotatably connected to the mounting base 2. The slider 502 is threadedly connected to the screw 503.

[0034] A guide rod 7 is slidably connected to the base 1, and a drilling device 8 is mounted on the guide rod 7. A drive component 9 is mounted on the base 1, and the drilling device 8 is driven by the drive component 9. During processing, the sheet metal part is pushed to the bottom of the drilling device 8 by the pusher assembly on the mounting base 2. Then, the drive component 9 on the base 1 is activated. The drive component 9 is a hydraulic rod, which drives the drilling device 8 to move steadily up and down along the guide rod 7. When the drill bit moves downward with the drilling device 8 and contacts the surface of the sheet metal part, the high-speed rotating drill bit will cut the sheet metal part to complete the drilling operation. The guide rod 7 provides precise guidance for the drilling device 8, reduces radial deviation during the drilling process, and improves drilling accuracy.

[0035] Working principle:

[0036] First, based on the thickness of the sheet metal part to be processed, the screw 503 is rotated by the fixed block on the screw 503, causing the slider 502 to drive the two adjusting plates 501 to slide synchronously, quickly adjusting the position of the two adjusting plates 501. The adjustment of the position of the adjusting plates 501 by the screw 503 can accommodate sheet metal parts of different thicknesses. Then, the spacing of the storage plates 6 is adjusted by pulling the connecting plate 402, so that the limiting block 403 is no longer locked with the limiting groove 404, the spring 406 retracts, and the turntable 304 is rotated by the connecting plate 402. The cam groove 305 and the drive shaft 306 roll, driving the guide block 302 to slide smoothly along the guide frame 301, so that the two storage plates 6 move away synchronously. The sheet metal part is placed between the two storage plates 6, and the spacing is adjusted by rotating the turntable 304 and the cam groove 305, avoiding the sheet metal part from getting stuck due to a fixed spacing, and ensuring that the sheet metal part slides smoothly.

[0037] After adjustment, loosen the connecting plate 402 to engage the limiting block 403 with the mounting shaft 303. The engagement of the limiting block 403 with the mounting shaft 303 ensures reliable positioning of the turntable 304, preventing the spacing of the storage plates 6 from shifting during processing and ensuring feeding stability. During processing, the sheet metal part is pushed to the bottom of the drilling device 8 by the pushing component on the mounting base 2. Then, the drive component 9 is activated to drive the drilling device 8 to make stable up and down movements. When the drilling device 8 moves downward and contacts the surface of the sheet metal part, the high-speed rotating drill bit will cut the sheet metal part to complete the sheet metal drilling. The guide rod 7 provides precise guidance for the drilling device 8, reducing radial deviation during the drilling process and improving drilling accuracy.

[0038] The sheet metal drilling machine in this solution is equipped with an expansion structure 3, allowing the operator to easily rotate the turntable 304. Utilizing the rolling interaction between the cam groove 305 and the drive shaft 306, the two storage plates 6 move synchronously towards or away from each other, thereby adjusting the placement space for the sheet metal parts. This avoids jamming and friction of sheet metal parts caused by fixed spacing, accommodating sheet metal parts of different sizes while ensuring smooth sliding and accurate positioning, thus improving workpiece placement efficiency and operational convenience.

[0039] Rotating the lead screw drives the slider to move the two adjusting plates, thus adjusting the guide distance between the two adjusting plates.

[0040] By engaging the spring-driven limit block 403 with the limit groove 404, the turntable 304 can be reliably locked, preventing it from rotating unexpectedly due to vibration or external force during processing.

[0041] The guide rod 7 provides guidance to ensure that the drilling device 8 reduces radial deviation and vibration during the pressing process.

[0042] The limit structure 4 is easy to operate and, combined with the lead screw adjustment, reduces the operator's operation time and labor intensity.

[0043] Example 2

[0044] In this embodiment, the structure of the punching machine is basically the same as that in Embodiment 1. The difference is that the original manual turntable 304 and lead screw 503 are replaced by servo motor drive control, which can improve the adjustment efficiency of the storage board spacing and the adjustment board spacing, so as to realize the electric precision control of the storage board spacing and the adjustment board spacing and improve the adjustment efficiency.
