Description

Technical Field

[0001] This utility model relates to the field of plate processing technology, and more specifically, to a novel plate drilling device. Background Technology

[0002] Drilling is a fundamental and crucial process in the production and processing of panel furniture. With the manufacturing industry moving towards automation and intelligence, CNC drilling equipment has become a mainstream production tool. Currently, common automated panel drilling equipment mainly uses a full servo CNC system to control the drilling depth. Its principle is that a servo motor drives a lead screw or rack and pinion mechanism to feed the drill bit. The drilling depth is controlled by preset program instructions from the CNC system, and the servo motor accurately calculates and positions the feed distance based on the number of rotations fed by the encoder. However, this method requires professional personnel to reprogram or modify parameters on the CNC system when processing holes of different depths or changing product models. The process is relatively cumbersome, lacks flexibility, and is not conducive to rapid changeover for small batches and diverse product types.

[0003] Traditional depth control uses mechanical stop limits. Adjustable physical stops are placed on the worktable, their positions determined by scale markings. The drill bit stops when it contacts the stop, thus determining the drilling depth. This method requires manual verification of the workpiece dimensions, conversion of these dimensions into stop position markings, manual adjustment of the stop position, and repeated testing and calibration. This is inefficient and cannot meet the demands of modern automated production lines for high efficiency and frequent changeovers. Furthermore, the stops are prone to wear or displacement after continuous impact from the drill bit, affecting the long-term stability of depth control.

[0004] Therefore, there is an urgent need in this field for a new type of plate drilling equipment that can ensure drilling depth accuracy and stability while also having good flexibility to quickly adapt to production changes. Utility Model Content

The hole depth calibration assembly includes a calibration base, a cantilever, and a calibration device; the cantilever is connected to the side of the calibration base near the worktable; the calibration device is disposed on the cantilever; the calibration base is slidably mounted on a slide rail, and the position of the hole depth calibration assembly is locked by locking the cantilever through a locking mechanism; a sensing surface is formed on the side of the calibration base near the drilling assembly; the drilling assembly is provided with a distance measuring module for detecting the distance between itself and the sensing surface.

[0008] Preferably, the horizontal distance between the drill bit tip and the ranging module of the drilling assembly is greater than the distance between the calibration device and the sensing surface. The hole depth calibration principle of this invention is as follows: the drill bit tip is moved until it is perpendicularly aligned with the calibration device; at this point, the distance between the sensing surface of the calibration base and the ranging module is recorded as the limit distance. Subsequently, each time a hole is drilled, the hole depth calibration assembly is pulled until it aligns with the hole depth to be drilled and then locked. When the ranging module measures the limit distance, the forward movement of the feed assembly is stopped, and it is reset backward, thus allowing the drilling depth to reach the position corresponding to the calibration device. The calibration position is intuitive and convenient for operators to adjust.

[0009] Preferably, the feed assembly includes a lead screw and nut transmission mechanism and a feed motor for driving the lead screw and nut transmission mechanism.

[0010] Preferably, the drilling assembly includes a drilling mounting base and a drilling motor mounted on the drilling mounting base; the drilling mounting base is slidably mounted on the frame via a slide rail and is connected to the feed assembly.

[0011] Preferably, the positioning auxiliary component includes a positioning mounting base and a plate fixing device for fixing the plate to the worktable; the positioning mounting base is disposed on the frame; the plate fixing device is disposed on the positioning mounting base; The positioning mounting base is also equipped with a drill bit anti-deviation auxiliary device to prevent the drill bit from shifting position, and an air blowing device to blow away the sawdust generated during drilling.

[0015] Preferably, it also includes a quick-change pad; the quick-change pad is laid on the workbench; the quick-change pad has a handle.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Example 1 This embodiment describes a novel plate drilling device, such as... Figures 1 to 5 As shown, it includes: frame; A worktable for placing the workpiece 6 to be processed; Positioning auxiliary component 4 is used to position and fix plate 6; Drilling assembly 2 with drill bit for drilling holes on the sides of plate 6; Feed assembly 1 is used to drive the drilling assembly 2 to reciprocate. And a hole depth calibration component 3 for calibrating borehole depth.

[0021] The worktable and positioning auxiliary component 4 are respectively mounted on the frame; the drilling component 2 is slidably mounted on the frame via the slide rail 102 and is connected to the feed component 1.

[0022] Specifically, the feed assembly 1 includes a lead screw and nut transmission mechanism 103 and a feed motor 101 for driving the lead screw and nut transmission mechanism 103.

[0023] The positioning auxiliary component 4 includes a positioning mounting base and a plate fixing device 404 for fixing the plate to the worktable; the positioning mounting base is mounted on the frame; the plate fixing device 404 is mounted on the positioning mounting base. The plate fixing device 404 preferably includes a plate clamping block and a clamping block cylinder for raising and lowering the plate clamping block. The clamping block cylinder presses the plate clamping block downwards to tighten the plate, thus fixing the plate to the worktable.

[0024] The drilling assembly 2 includes a drilling mounting base 203 and a drilling motor 201 mounted on the drilling mounting base 203. The drilling mounting base 203 is slidably mounted on the frame via a slide rail 102 and is connected to the lead screw and nut transmission mechanism 103 of the feed assembly 1.

[0025] The positioning mounting base is also equipped with a drill bit 202 anti-deviation auxiliary device 401 to prevent the drill bit 202 from shifting position. The positioning mounting base has an anti-deviation mounting hole. The drill bit 202 anti-deviation auxiliary device 401 includes a bearing. The bearing is set in the anti-deviation mounting hole. The drill bit 202 passes through the bearing hole. The inner diameter of the bearing hole is slightly larger than the diameter of the drill bit 202. The drill bit anti-deviation auxiliary device provides effective support and guidance for the slender drill bit, effectively preventing the drill bit from deviating, drifting, or breaking, and ensuring the accuracy of the hole position and the perpendicularity of the hole wall.

[0026] The positioning mounting base is also equipped with an air blowing device 403 for blowing away wood chips generated during drilling. The air blowing device can effectively avoid drill bit wear, workpiece material burns, and drill bit jamming caused by chip blockage, extend the service life of the drill bit, and ensure the smoothness of the inner wall of the hole.

[0027] The hole depth calibration assembly 3 includes a calibration base 303, a cantilever 301, and a calibration device 302. The cantilever 301 is connected to the side of the calibration base 303 near the worktable. The calibration device 302 is disposed on the cantilever 301. The calibration device 302 includes a calibration post. The cantilever 301 is provided with a calibration mounting hole. The calibration post is movably inserted into the calibration mounting hole and self-reset after downward movement is achieved by an elastic element.

[0028] The calibration base 303 is slidably mounted on the slide rail 102, and the position of the hole depth calibration component 3 is locked by locking the cantilever 301 through the locking mechanism 402. The locking mechanism 402 includes a lifting cylinder; the lifting cylinder is preferably mounted on the positioning mounting base.

[0029] A sensing surface 304 is formed on the side of the calibration base 303 near the drilling assembly 2; the drilling assembly 2 is provided with a ranging module 104 for detecting the distance between itself and the sensing surface 304. The horizontal distance between the tip of the drill bit 202 of the drilling assembly 2 and the ranging module 104 is greater than the distance between the calibration device 302 and the sensing surface 304. The sum of the distance L1 between the calibration device 302 and the sensing surface 304 and the limiting distance L3 between the sensing surface 304 and the ranging module 104 matches the horizontal distance L2 between the tip of the drill bit 202 of the drilling assembly 2 and the ranging module 104.

[0030] The hole depth calibration principle of this utility model is as follows: the front end of the drill bit 202 is moved to be vertically aligned with the calibration device 302. At this time, the distance between the sensing surface 304 of the calibration base 303 and the ranging module 104 is recorded as the limit distance. Then, each time a hole is drilled, the hole depth calibration assembly 3 is pulled until the calibration device 302 is aligned with the hole depth to be processed and locked. When the ranging module 104 measures the limit distance, the forward movement of the feed assembly 1 is stopped and it is reset backward, thus allowing the drilling depth to reach the position corresponding to the calibration device 302. The calibration position is intuitive and convenient for operators to adjust. According to the above principle, the sum of the distance L1 between the calibration device 302 and the sensing surface 304 and the limit distance L3 between the sensing surface 304 and the ranging module 104 is approximately equal to the horizontal distance L2 between the front end of the drill bit 202 of the drilling assembly 2 and the ranging module 104.

[0031] The drilling process of this plate drilling equipment is as follows: Loading and fixing: Place the plate to be processed 6 on the worktable and start the plate fixing device 404 of the positioning auxiliary component 4 to fix the plate 6; Hole depth calibration: Pull the hole depth calibration component 3 along the slide rail 102 to near the target drilling position; press the self-resetting calibration post for precise positioning; for example, when it is necessary to drill a hole from the side of the plate 6 that communicates with the plate mounting hole 601 in the middle of the plate 6, align the calibration post perpendicularly with the plate mounting hole 601, such as... Figure 1 As shown, positioning is determined by observing whether the calibration post penetrates the mounting hole 601 of the plate when it is pressed; for example, if through holes need to be drilled through both sides of the plate 6, the calibration post will reach the outer side of the plate, as shown. Figure 5 As shown, the drill bit tip eventually passes through the side of the plate; after positioning, the locking mechanism is activated to lock the position of the hole depth calibration component; Drilling execution: Start the feed assembly and drilling assembly to drill holes in the sheet metal; Depth control and retraction: When the ranging module measures the limit distance, the forward movement of the feed component stops and it resets backward; Reset and unload.

[0032] This invention significantly enhances the flexible production capabilities of the equipment. When processing different specifications of plates or when the hole depth requirements change, there is no need for complex program reprogramming or servo parameter adjustment. Simply move and lock the hole depth calibration component. The preset hole depth calibration point can be observed intuitively, allowing operators to quickly and flexibly preset the hole depth calibration point according to the depth requirements of different hole positions on the plate. This greatly shortens the production preparation time and is particularly suitable for flexible manufacturing scenarios with small batches and multiple varieties. This invention avoids the impact of wear or positional displacement of traditional stops on positioning accuracy through non-contact sensing between the ranging module and the sensing surface of the calibration base, thereby improving drilling accuracy and working stability.

[0033] Example 2 This embodiment describes a novel plate drilling device, which differs from Embodiment 1 in that: Figure 6 As shown, this embodiment also includes a quick-change pad 5; the quick-change pad 5 is laid on the workbench; the quick-change pad 5 has a handle 501. By placing quick-change pads 5 of different thicknesses on the workbench, or without placing quick-change pads, the drilling position of plates of different thicknesses can be aligned with the drill bit position, meeting the drilling needs of plates of various thicknesses, improving the versatility of the equipment, and making operation simple and convenient.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
