Description

Technical Field

[0001] This utility model belongs to the field of machining, and in particular relates to a punching device for equidistant holes. Background Technology

[0002] In the field of machining, drilling machines are fundamental equipment for drilling holes in materials. Traditionally, before drilling with a conventional drilling machine, manual labor is required to mark the hole center position on the material using tools such as height gauges and scribers, and to create a sample hole to finalize the drilling location. This process is particularly problematic when machining a large number of equidistant holes with small spacing: repeated measurement, marking, and sample hole creation are not only tedious and time-consuming, but also prone to increasing cumulative errors due to visual fatigue or operational mistakes, severely restricting production efficiency and machining accuracy. Utility Model Content

[0003] The purpose of this invention is to provide a punching device for equidistant holes to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the specific technical solution of the equidistant hole punching device of this utility model is as follows: A punching device for equidistant holes includes an operating table with legs, a moving device on the operating table for moving material, and a punching device for punching holes in the material. The material on the moving device is located directly below the punching device. The moving device includes a worktable slidably mounted on the operating table and a fixing device on the worktable for limiting the material's movement. The punching device includes a bracket on the operating table surface, a lifting device vertically mounted on the bracket, and a hole-forming assembly slidably mounted on the bracket. The lifting device is connected to the hole-forming assembly and can drive it to reciprocate. The hole-forming assembly includes a mounting frame slidably mounted within the bracket and connected to the lifting device, a loading plate rotatably mounted on the mounting frame, and multiple detachable and position-adjustable alloy punches on the circumference of the loading plate. The material on the fixing device is located directly below the loading plate.

[0005] Furthermore, the bracket is ∩-shaped, with sliding grooves on its two side walls. The mounting bracket is ∩-shaped, with limiting blocks on both side walls that can be inserted into and slide within the sliding grooves, and the side walls of the limiting blocks are provided with composite plates that slide in conjunction with the sliding grooves.

[0006] Furthermore, a T-slot 1 is formed around the circumference of the loading disc. The alloy punch includes a T-bolt detachably disposed in the T-slot 1, a punch head provided on the T-bolt, a flat washer fitted on the T-bolt, and a punch locking nut threadedly connected to the T-bolt.

[0007] Furthermore, the fixing device includes a T-bolt slidably mounted on the worktable, and a T-slot 2 for the T-bolt to slide on the worktable. Multiple T-slots are symmetrically arranged on the worktable with their longitudinal center along the length of the worktable. A pressure plate is fitted onto the T-bolt, and a locking nut is provided on the T-bolt above the pressure plate to lock it in place. Material is placed between two parallel pressure plates.

[0008] Furthermore, a T-slot 3 is formed on the bottom surface of the worktable, and a T-shaped guide rail is installed on the top surface of the worktable via countersunk bolts. The worktable is slidably mounted on the T-shaped guide rail via the T-slot 3. A drive device is provided on the worktable to drive its reciprocating movement.

[0009] Furthermore, the drive unit includes a planetary reducer detachably mounted on the operating table via countersunk bolts 3 and an AC servo motor connected to the planetary reducer. The output end of the planetary reducer passes through the operating table and is connected to the worktable via a transmission unit. The transmission unit includes a gear located at the output end of the planetary reducer, a rack located on the side wall of the worktable and meshing with the gear, and the rack is detachably connected to the worktable via countersunk bolts 2.

[0010] The equidistant hole punching device of this utility model has the following advantages: This invention utilizes the cooperation between a moving device and a punching hole device. The alloy punch in the punching hole device first punches the first sample hole with the material fixed on the moving device. Then, as the moving device moves the material, the loading plate in the punching hole device rotates under the cooperation of the alloy punch and the material, so that adjacent alloy punches punch the material. In this way, the remaining alloy punches on the loading plate punch the material in sequence, thereby achieving the purpose of punching the material with equidistant sample holes.

Detailed Implementation

[0013] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an equidistant hole punching device of this utility model.

[0014] like Figures 1 to 6 As shown, this utility model discloses an equidistant hole punching device, comprising an operating table 1 with supporting legs, a moving device on the operating table 1 for moving a material 28, and a punching device for punching holes in the material 28 on the operating table 1. The material 28 on the moving device is located directly below the punching device. Specifically, the moving device includes a worktable 15 slidably mounted on the operating table 1 and a fixing device on the worktable 15 for limiting the movement of the material 28. The punching device includes a support 2 mounted on the surface of the operating table 1, a lifting device vertically mounted on the support 2, and a hole forming assembly slidably mounted on the support 2. The lifting device is connected to the hole forming assembly and can drive it to reciprocate.

[0015] The hole-forming assembly includes a mounting frame 10 slidably mounted within a support 2 and connected to a lifting device, a loading plate 3 rotatably mounted on the mounting frame 10, and multiple detachable and position-adjustable alloy punches 4 located on the circumference of the loading plate 3. The material 28 on the fixing device is positioned directly below the loading plate 3 so that the alloy punches 4 can punch holes in the material 28. In use, the material 28 to be processed is securely fixed to the worktable 15 using the fixing device. By pushing the worktable 15 to slide it on the operating table 1, the starting end of the material 28 to be punched is moved directly below the hole-forming assembly, aligning the position of the first hole to be punched with the alloy punch 4 directly below the loading plate 3. The lifting device is activated, driving the mounting frame 10 and the loading plate 3 downwards. Under pressure, the alloy punch 4 aligned on the loading plate 3 punches out the first precise hole on the surface of the material 28. After the first punching is completed, the lifting device remains in a downward-pressing state, and the end of the punch sinks into the hole just punched, serving as a positioning and fulcrum. The operator pushes the worktable 15, along with the material 28 fixed on it, in a straight line. Since the first alloy punch 4 has been pressed into the material 28, a huge frictional force is generated between them. This frictional force makes the moving material 28 act like a "rack 21," and the pressing punch like the teeth of a "gear 23," thereby driving the entire loading tray 3 to rotate. As the worktable 15 moves, the loading tray 3 rotates at a constant speed. When the moving distance is exactly equal to the circumferential distance between adjacent punches on the loading tray 3, the next adjacent alloy punch 4 reaches its lowest point under the action of rotation and automatically presses into the surface of the material 28 under continuous downward pressure, forming a second sample hole. This cycle repeats: the current alloy punch 4 presses into the material 28 - pushes the worktable 15 - drives the loading tray 3 to rotate - the next punch automatically presses in, automatically punching out a row of sample holes with completely consistent spacing, until the end of the material 28 is finished. The lifting device used to raise and lower the mounting frame 10 is a hydraulic cylinder 7. The hydraulic pump of the hydraulic cylinder 7 is connected to an external power source. The hydraulic cylinder 7 is detachably mounted on the bracket 2 via a locking bolt 8, and a spring washer 9 is also fitted onto the locking bolt 8. As the hydraulic cylinder 7 is prior art, it will not be described in detail here.

[0016] It should be noted that this device can convert the linear motion of material 28 into the rotational motion of loading plate 3, achieving automated sequential stamping through a mechanical structure. After one stamping cycle, no additional power or operation is required to lift the punch or change positions. Simply pushing the worktable 15 linearly moves the loading plate 3 to automatically rotate and position the next punch at the stamping position, realizing a continuous and rapid automatic stamping cycle, thus improving production efficiency. This solves the tedious process of traditional repetitive manual marking and pattern punching. The operator only needs to complete three actions: clamping, pushing the worktable 15, and applying pressure to punch the hole, requiring no technical experience. The entire processing is smooth and fast, with low requirements for the operator's technical level, and ordinary workers can immediately learn to operate it. Furthermore, the loading plate 3 and the alloy punch 4 are detachably connected, allowing for quick replacement when one of the alloy punches 4 wears out, saving time. At the same time, the position of the alloy punch 4 on the loading plate 3 can be flexibly adjusted and fixed according to the required hole spacing to meet the needs of processing different equidistant holes. It should be noted that the spacing between adjacent alloy punches 4 should not be too large. It is necessary to ensure that when the material 28 pushes and presses the alloy punch 4, the adjacent punches must contact and press the material 28.

[0017] like Figure 2 As shown, both the bracket 2 and the mounting frame 10 are ∩-shaped, with sliding grooves 27 on both side walls of the bracket 2. Simultaneously, each side wall of the mounting frame 10 is provided with a limiting block 101 that can be inserted into and slide within the sliding groove 27. The side wall of the limiting block 101 is provided with a composite plate 14 that slides with the sliding groove 27, thus allowing the mounting frame 10 to move only vertically on the bracket 2. The operator controls the lifting device to apply downward pressure, which is transmitted to the mounting frame 10 through the bracket 2. The composite plates 14 on both sides of the mounting frame 10 and the sliding grooves 27 on the bracket 2 form a sliding pair, allowing the mounting frame 10 to move only vertically downwards. Until the alloy punch 4 at the lowest point, under the vertical downward pressure, presses into the surface of the material 28, forming the first sample hole.

[0018] It should be noted that a rotating shaft is coaxially provided at the center of the loading plate 3, and stepped holes for mounting bearings 11 are opened on the two vertical plates of the mounting frame 10. The two ends of the rotating shaft are respectively connected to their corresponding bearings 11, and the bearings 11 are fixed to the mounting frame 10 by end caps 12. The end caps 12 are detachably provided on the mounting frame 10 by end cap bolts 13.

[0019] To achieve a detachable connection between the alloy punch 4 and the loading plate 3, a T-slot 129 is formed around the circumference of the loading plate 3. The alloy punch 4, used for punching sample holes, includes a T-bolt detachably disposed within the T-slot 129, with a punching head mounted on the T-bolt. To secure the T-bolt within the T-slot 129, a flat washer 6 is fitted onto the T-bolt, and a punch locking nut 5 is threaded onto the T-bolt. This combination of the T-slot 129, T-bolt, and punch locking nut 5 allows for stepless adjustment and secure locking of the radial position of each alloy punch 4 on the circumference of the loading plate 3. This enables the device to not only punch equidistant sample holes but also, by pre-setting the positions of the alloy punches 4, process non-equidistant sample holes where adjacent alloy punches 4 can be automatically punched by the material 28, conforming to the processing steps of the device. Furthermore, the detachable connection between the alloy punch 4 and the loading plate 3 allows for the pre-installation of alloy punches 4 of different specifications, such as alloy punches 4 of different diameters and shapes, on the loading plate 3, thereby improving the practicality of the device.

[0020] The shape of the T-bolt, being existing technology, will not be elaborated upon here. It should be noted that the base width of the T-bolt is either compatible with or smaller than the outer diameter of the T-slot 129, facilitating insertion. After insertion, the T-bolt is rotated to engage its base within the slot. Then, based on the required hole spacing, the T-bolts of each alloy punch 4 are slid to their precise radial positions. Next, the flat washers 6 are sequentially fitted, and the punch locking nuts 5 are tightened. The threaded locking force, through the flat washers 6, firmly secures the T-bolts within the T-slot 129, completing the pre-setting of all punches.

[0021] like Figure 5 As shown, the fixing device for limiting the material 28 includes a T-bolt 17 slidably disposed on the worktable 15, and a T-slot 230 for sliding the T-bolt 17 is provided on the worktable 15. Multiple T-slots are symmetrically arranged on the worktable 15 with their longitudinal center, and the T-slots are arranged along the length direction of the worktable 15.

[0022] A pressure plate 16 is fitted onto the T-bolt 17, and a locking nut 18 is located on the T-bolt 17 above the pressure plate 16 to lock it in place. The material 28 is placed between the two parallel pressure plates 16, and the material 28 is fixed in place by the cooperation of the locking nut 18, the T-bolt 17, and the pressure plate 16. Furthermore, the symmetrically arranged pressure plates 16 can apply force evenly from both sides of the material 28, preventing the material 28 from moving or vibrating during processing. At the same time, by adjusting the distance between the two pressure plates 16 or the T-bolt 17, rectangular or square materials 28 of different widths and shapes can be quickly and securely clamped, further improving the practicality of this device.

[0023] It should be noted that a long groove is provided on the pressure plate 16, and the width of the long groove is adapted to the diameter of the T-bolt 17. The pressure plate 16 can move on the T-bolt 17 through the long groove, so that when the pressure plate 16 is used to fix and press the material 28, the pressure plate 16 can tilt and be fixed by the lock nut 18.

[0024] In use, select the symmetrical T-slots 230 on the worktable 15 according to the width of the material 28, insert the two T-bolts 17 into the slots, and move them to the appropriate positions. Place the pressure plate 16 on the T-bolts 17, ensuring its inner side is tightly against both sides of the material 28. The pressure plate 16 securely clamps the material 28 onto the worktable 15. Then, tighten the pressure plate 16 with the lock nut 18.

[0025] Still Figure 5 As shown, the sliding of the worktable 15 on the operating table 1 specifically includes a T-slot 331 on the bottom surface of the worktable 15, and a T-shaped guide rail 19 on the top surface of the operating table 1 via countersunk bolts 120. The worktable 15 is slidably mounted on the T-shaped guide rail 19 via the T-slot 331. In order to facilitate the movement of the worktable 15 and save manpower, a drive device is provided on the operating table 1 to drive the worktable 15 to reciprocate.

[0026] Specifically, the drive unit includes a planetary reducer 24 detachably mounted on the operating table 1 via countersunk bolts 325, and an AC servo motor 26 connected to the planetary reducer 24. The AC servo motor 26 is connected to an external power supply. The output end of the planetary reducer 24 passes through the operating table 1 and is connected to the worktable 15 via a transmission unit. The transmission unit includes a gear 23 located at the output end of the planetary reducer 24, and a rack 21 located on the side wall of the worktable 15 and meshing with the gear 23. The rack 21 is detachably connected to the worktable 15 via countersunk bolts 222. The AC servo motor 26 is started. The AC servo motor 26 increases its output torque and decreases its speed through the planetary reducer 24. The output end of the planetary reducer 24 drives the gear 23 to rotate. The gear 23 meshes with the rack 21 fixed to the side wall of the worktable 15, converting the rotational motion of the AC servo motor 26 into precise, uniform linear motion of the worktable 15. The worktable 15, along with the material 28, moves automatically. After the material 28 is stamped, the lifting device can be controlled to lift the alloy punch 4, and the AC servo motor 26 can be reversed to drive the planetary reducer 24 to reverse as well. The planetary reducer 24 will then drive the worktable 15 to move back to its initial position via the transmission unit. The AC servo motor 26 is connected to the control panel, which allows for precise control of the feed speed of the AC servo motor 26 to adapt to the requirements of different materials and stamping depths.

[0027] Instructions for use: Based on the required hole spacing, insert the T-bolts of each alloy punch 4 into the T-slots 129 of the loading plate 3, sliding them to the precise radial position. Then, sequentially install the flat washers 6 and tighten the punch locking nuts 5 to firmly secure the T-bolts, completing the preset of all punches. Next, place the material 28 on the worktable 15, and according to the width of the material 28, select the T-slot 230 on the worktable 15, insert the two T-bolts 17 into the slots, install the pressure plate 16, and tighten the locking nut 18 to secure the material 28 firmly on the worktable 15. Then, move the starting end of the material 28 directly below the loading plate 3 and align it with the alloy punch 4 located directly below the loading plate 3. Operate the lifting device to apply downward pressure and hold, pressing the punch into the surface of the material 28 to form the first sample hole. Start the AC servo motor 26. The AC servo motor 26 drives the planetary reducer 24, and the output end of the planetary reducer 24 drives the gear 23 to rotate. Gear 23 meshes with rack 21 fixed to the side wall of worktable 15, converting the rotational motion of AC servo motor 26 into linear motion of worktable 15. The automatic movement of worktable 15, along with the material 28, drives the loading tray 3 to rotate, thus achieving continuous stamping cycles on the material 28. After the entire row of sample holes is processed, the lifting device is operated to raise the alloy punch 4. The AC servo motor 26 is controlled to reverse, driving worktable 15 back to its initial position. Loosening the locking nut 18 allows the processed material 28 to be removed.
