Abstract
Description
Technical Field
[0001] This utility model relates to the field of machine tool technology, specifically to a single-axis drilling machine for bamboo with unequal spacing. Background Technology
[0002] Qiong bamboo, a bamboo species with unique internode structure and aesthetic value, is widely used to make high-value-added products such as walking sticks, furniture, and handicrafts. During the processing of Qiong bamboo handicrafts, it is often necessary to drill holes in the bamboo shaft for subsequent splicing, decoration, or functional assembly. However, the spacing between holes in Qiong bamboo is sometimes unequal. Operators use electric drills or bench drills to manually position and drill the bamboo, resulting in insufficient production efficiency and significant safety hazards. Although high-precision multi-axis CNC machine tools can accomplish this task, their high equipment cost and complex programming operations place an excessive economic burden on small and medium-sized enterprises and individual craftsmen primarily engaged in Qiong bamboo handicraft processing. Furthermore, the redundant functions do not align with their actual production efficiency.
[0003] Existing technologies, such as Chinese utility model patent with publication number CN202320563850, disclose a "drilling machine for bamboo product production." By controlling the connecting plate to move downwards, the bottom surface of the pressure plate first contacts the bottom surface of the drill bit through the housing and guide rod. The spring force is used to press the bottom surface of the pressure plate tightly against the bamboo product, thus compacting the area around the drill bit and preventing breakage around the drill bit during drilling. However, due to the smooth and curved surface of bamboo, this device is difficult to use for fixing and processing bamboo poles. Existing technologies lack a dedicated device for drilling bamboo that can accurately guarantee the processing requirements of unequal hole positions while also possessing the advantages of high efficiency and low cost. Utility Model Content
[0004] The purpose of this invention is to provide a special machine tool that can reliably clamp and accurately complete unequal-distance drilling, thereby improving the processing quality and efficiency of bamboo handicrafts.
[0005] To achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution: a single-axis drilling machine for bamboo with unequal spacing, characterized in that it includes a frame, an adjustment mechanism, and a fixing mechanism. The adjustment mechanism includes multiple support rods fixedly installed above the frame. A first linear module is fixedly installed above the support rods. A second linear module is fixedly installed at the output end of the first linear module. A drilling motor is fixedly installed at the output end of the second linear module. The fixing mechanism includes two symmetrical guide rails fixedly installed above the frame. Multiple sliders are symmetrically slidably installed on each pair above the guide rails. A connecting plate is fixedly installed above the symmetrical sliders on both sides. A pad is fixedly installed above the connecting plate. A slide cylinder is fixedly installed above the pad. Two clamping blocks are symmetrically fixedly installed above the slide cylinder.
[0006] Furthermore, the first linear module and the second linear module are ball screw modules, and the first linear module and the second linear module are distributed perpendicularly.
[0007] Furthermore, the slider is a slider with a manual threaded lock.
[0008] Furthermore, the axis of the slide cylinder intersects with the axis of the drill bit of the drilling motor.
[0009] Furthermore, the clamping surface of the clamping block is provided with a V-shaped groove, and an anti-slip rubber pad is pasted inside the V-shaped groove.
[0010] Compared with related technologies, the single-axis drilling machine for unequal spacing of bamboo provided by this utility model has the following beneficial effects:
[0011] 1. This utility model uses a high-precision ball screw linear module to form a two-dimensional moving platform, which drives the drilling motor for positioning. It can accurately control the moving distance of the drill bit in the length direction of the bamboo, thereby strictly ensuring the preset unequal distance size requirements between each hole position, effectively avoiding human error caused by manual measurement and positioning, and significantly improving the processing quality and consistency of the product.
[0012] 2. This utility model adopts a combination of a clamping block with a V-groove and a sliding cylinder. The V-groove structure can automatically adapt to and align the cylindrical bamboo stick, achieving automatic centering. It cooperates with the V-groove on the other side to form a stable four-point clamping. The anti-slip rubber pad pasted inside the groove greatly increases the clamping friction, ensuring that the bamboo stick will not rotate, move, or vibrate during the drilling process.

[0021] Example 1
[0022] See Figures 1 to 4 As shown, a single-axis drilling machine for bamboo with unequal spacing is characterized by comprising a frame 1, an adjustment mechanism 2, and a fixing mechanism 3. The adjustment mechanism 2 includes multiple support rods 21 fixedly installed above the frame 1. A first linear module 22 is fixedly installed above the support rods 21. A second linear module 23 is fixedly installed at the output end of the first linear module 22. A drilling motor 24 is fixedly installed at the output end of the second linear module 23. The fixing mechanism 3 includes two symmetrical guide rails 31 fixedly installed above the frame 1. Multiple sliders 32 are symmetrically slidably installed above the guide rails 31. A connecting plate 33 is fixedly installed above the symmetrical sliders 32 on both sides. A pad 34 is fixedly installed above the connecting plate 33. A slide cylinder 35 is fixedly installed above the pad 34. Two clamping blocks 36 are symmetrically fixedly installed above the slide cylinder 35. The position of the drilling motor 24 is adjusted by the first linear module 22 and the second linear module 23, which facilitates the adjustment of the drilling distance between the drill bit and the bamboo. The distance between the multiple sliding cylinders 35 is adjusted by the slider 32 installed on the guide rail 31. The bamboo can be fixed according to the length of the bamboo. In addition, the sliding cylinders 35 can push the clamping blocks 36 on both sides to move in opposite directions to fix the bamboo, thus making the bamboo more stable during processing.
[0023] The first linear module 22 and the second linear module 23 are ball screw modules, and they are vertically distributed. The ball screw achieves movement through the rolling of balls between the screw and the nut, featuring low frictional resistance, high positioning accuracy, no backlash, and high transmission efficiency. In bamboo drilling, especially when achieving complex, unequal-distance holes, the ball screw module ensures that the drilling motor 24 remains accurately positioned after movement and stop. The vertically distributed first linear module 22 and second linear module 23 ensure that the movements of the two axes do not interfere with each other, together forming a stable and reliable two-dimensional precision motion platform.
[0024] The slider 32 is a slider 32 with a manual threaded lock. When the slider 32 is manually moved to the predetermined position, the threaded locking mechanism is tightened to mechanically lock any movement of the slider 32 on the guide rail 31, thereby making the processing of bamboo more stable.
[0025] The axis of the slide cylinder 35 intersects with the axis of the drill bit of the drilling motor 24. Since the center of the drill hole is located at the clamping center of the slide cylinder 35, the extrusion pressure on both sides of the bamboo is the same. Therefore, during processing, not only is the drilling position located at the center of the bamboo, but the resistance to drill bit torque is also improved.
[0026] The clamping surface of the clamping block 36 is provided with a V-shaped groove 361, and an anti-slip rubber pad 362 is attached inside the V-shaped groove 361. The inclined structure of the V-shaped groove 361 allows it to naturally accommodate and position the cylindrical bamboo stick. Regardless of slight differences in the diameter of the bamboo stick, it ensures that the center line of the bamboo stick is always constrained near the angle bisector of the V-shaped groove 361, thereby achieving automatic centering. At the same time, it cooperates with the V-shaped groove 361 on the other side to form a stable four-point clamping. Furthermore, the anti-slip rubber pad 362 increases the friction, further preventing the bamboo stick from rolling and moving on the horizontal surface.
[0027] Example 2
[0028] The drilling motor 24 of this utility model has a drill bit installed at its output end;
[0029] The slide cylinder 35 of this utility model can be an MHF2 type slide cylinder 35;
[0030] The first linear module 22 and the second linear module 23 of this utility model are equipped with accordion protective covers to prevent the dust from the bamboo processing from affecting the transmission.
[0031] The first linear module 22, the second linear module 23, the slide cylinder 35, and the drilling motor 24 of this utility model are electrically connected to an external CNC device.
[0032] The locking device inside the slider 32 of this utility model is the existing slider 32 locking structure.
[0033] Example 3
[0034] Working principle: First, the operator manually adjusts the positions of multiple sliders 32 mounted on two symmetrical guide rails 31 in the fixing mechanism 3 according to the length of the bamboo to be processed. By loosening and locking the manual threaded locking device on the sliders 32, multiple sets of sliding cylinders 35 can be moved to the corresponding positions suitable for supporting bamboo of that length. Then, the bamboo is placed between the two clamping blocks 36 above each sliding cylinder 35, and the sliding cylinder 35 is activated, driving the two symmetrically mounted clamping blocks 36 above it to move towards each other. The V-shaped groove 361 on the clamping surface of the clamping block 36 can automatically adapt to and align the cylindrical bamboo rod, achieving automatic centering. At the same time, the anti-slip rubber pad 362 attached inside the V-shaped groove 361 increases the friction of the clamping surface, effectively preventing the bamboo rod from rotating or moving during drilling, ensuring the absolute stability of the workpiece during processing. The design of the axis of the slide cylinder 35 intersecting with the axis of the drill bit of the drilling motor 24 makes the center of clamping force directly opposite the center of drilling force, further enhancing the system's stability against drill bit torque.
[0035] After the bamboo is reliably fixed, the operator controls the adjustment mechanism 2 for precise positioning according to the preset unequal hole spacing requirements. The adjustment mechanism 2 consists of a first linear module 22 and a second linear module 23 arranged perpendicularly to each other, forming a two-dimensional moving platform to ensure that the drill bit can be vertically aligned with the position of the hole to be drilled on the bamboo pole. Due to the use of a high-precision ball screw module, the platform can achieve high-precision displacement without backlash, thereby accurately ensuring the unequal spacing requirements of each hole position in the length direction of the bamboo. When the drill bit moves to the predetermined coordinate through the adjustment mechanism 2, the drilling motor 24 is started, and the motor drives the drill bit to rotate at high speed. Then, the second linear module 23 is controlled to drive the drilling motor 24 to feed towards the bamboo to complete the drilling operation. After one hole is processed, the drilling motor 24 retracts, and the first linear module 22 then drives the entire drilling unit to move to a new position according to the spacing requirements of the next hole position, repeating the above drilling process until all unequal holes are processed.
