Description

Technical Field

[0001] This utility model relates to the technical field of wood drilling devices, specifically a wood processing drilling device. Background Technology

[0002] Wood is the lignified tissue formed by plants capable of secondary growth, such as trees and shrubs. After the primary growth of these plants ends, the vascular cambium in the rootstock begins to function, developing phloem outward and wood inward. Wood is the collective term for plant tissues that develop inward from the vascular cambium, including xylem and parenchyma rays. Wood plays a significant supporting role in human life.

[0003] Extensive research revealed that prior art publication number CN 212123593 U discloses a wood processing drilling device, including a fixed block, an inner plate, a slot, and a cavity. A crossbar is located within the cavity, and a slider is slidably connected to the crossbar. This device can rotate a threaded rod, causing it to rotate a rotating block within a slot, controlling the horizontal movement of a connecting block. During this process, a cylinder moves horizontally with precision. Alternatively, pulling the connecting plate upwards causes the connecting plate to disengage the insert block from the slot. Simultaneously, the sliding rod slides within the slot, compressing a spring. Moving the connecting rods on both sides causes the connecting rod to slide the slider on the crossbar until it reaches the desired position. Releasing the connecting plate then releases the spring, causing the sliding rod to slide within the slot, inserting the insert block into the slot and fixing the position of the connecting rod.

[0004] Therefore, based on the above search and combined with existing information, during the drilling process, the drill bit rotates and carries out wood chips from the wood, causing the wood chips to accumulate, which leads to heat dissipation of the drill bit, resulting in overheating, accelerated wear, and shortened service life. At the same time, the accumulation of wood chips may also cause instability during the drilling process, resulting in uneven hole diameter, rough hole wall, and other instability. To address this, we propose a wood processing drilling device. Utility Model Content

[0005] The purpose of this invention is to provide a wood processing drilling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wood processing drilling device, comprising a base, a support rod fixedly mounted on the upper end of the base by bolts, a housing slidably mounted on the outer surface of the support rod, a drive motor fixedly mounted on the inner end of the housing, a connecting shaft rotatably mounted on the bottom end of the housing, and a drive shaft fixedly mounted on the inner end of the connecting shaft, the drive shaft being fixedly connected to the output end of the drive motor, a dust suction device for preventing wood chips and dust from floating during drilling being provided below the connecting shaft, and a drill bit for drilling being detachably mounted below the drive shaft.

[0007] As a further embodiment of this utility model, the dust collection device includes a stabilizing shell, which is sleeved on the outer surface of the connecting shaft, the drill bit is located inside the stabilizing shell, and a corrugated pipe is fixedly installed at the bottom end of the stabilizing shell.

Both ends of the connector are rotatably installed with buckles, and a slanted block is fixedly installed at the end of the buckle near the drill bit. The slanted block is engaged in the groove on the outer surface of the drill bit.

[0011] As a further embodiment of this utility model, the outer surface of the stabilizing shell is provided with threaded holes, which correspond to the buckles at the left and right ends of the connector. Stabilizing bolts are threaded into the threaded holes, and when the stabilizing bolts rotate, they abut against the buckles near the connector.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When using this utility model, the sawdust is sucked away in time during the drilling process, which can reduce dust and debris in the working area, keep the working environment clean, reduce the risk of operators inhaling harmful dust, and greatly reduce the cleaning work after drilling is completed by sucking away sawdust, saving time and energy.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Example 1: Please refer to Figures 1-2 A wood processing drilling device includes a base 1, a support rod 2 fixedly installed on the upper end of the base 1 by bolts, a housing 5 slidably installed on the outer surface of the support rod 2, and a rack 3 fixedly welded to the outer surface of the support rod 2. A drive gear is rotatably installed on the inner end of the housing 5, and the drive gear meshes with the rack 3. An adjusting ring 4 is rotatably installed on the front end of the housing 5, and the adjusting ring 4 is fixedly connected to the drive gear by bolts. Rotating the adjusting ring 4 drives the drive gear to rotate, and under the action of meshing with the rack 3, it drives the housing 5 to move upward or downward.

[0024] Please see Figure 2 , 3A drive motor 101 is fixedly installed at the inner end of the housing 5, and a connecting shaft 205 is rotatably installed at the bottom end of the housing 5. A drive shaft 207 is fixedly installed at the inner end of the connecting shaft 205. The drive shaft 207 is fixedly connected to the output end of the drive motor 101. Specifically, there is a certain gap between the drive shaft 207 and the connecting shaft 205, and they are fixedly connected by a connecting block.

[0025] like Figure 2 As shown, the front end of the housing 5 is provided with a dust outlet 103, which corresponds to the gap between the drive shaft 207 and the connecting shaft 205. More specifically, the dust outlet 103 is fixedly connected to the input end of the vacuum cleaner (not shown in the figure), and the vacuum cleaner absorbs the wood chips generated during drilling.

[0026] A dust collection device is provided below the connecting shaft 205 to prevent sawdust and dust from floating during drilling, and a drill bit 102 for drilling is detachably installed below the drive shaft 207.

[0027] Example 2: Please refer to Figure 2 , 4 A wood processing drilling device, which differs from Embodiment 1 in that the dust collection device includes a stabilizing shell 201, which is sleeved on the outer surface of the connecting shaft 205. The drill bit 102 is located inside the stabilizing shell 201. Specifically, a locking block is fixedly installed on the outer surface of the connecting shaft 205. A slot is opened at one end of the stabilizing shell 201 near the connecting shaft 205. During installation, the stabilizing shell 201 is screwed onto the outer surface of the connecting shaft 205 so that the locking block is engaged in the slot. A fixing sleeve 206 is threaded onto the outer surface of the connecting shaft 205. The fixing sleeve 206 is rotated so that its bottom end is tightly attached to the upper end of the stabilizing shell 201, thereby further fixing the stabilizing shell 201.

[0028] Please see Figure 4 , 5 6. A corrugated pipe 202 is fixedly installed at the bottom of the stabilizing shell 201. The corrugated pipe 202 is made of high-strength heat-resistant rubber and has the characteristics of being stretchable and retractable. When the drill bit 102 drills wood, the corrugated pipe 202 can retract, thereby always enveloping the drill bit 102. A stabilizing ring 203 is fixedly connected to the end of the corrugated pipe 202 away from the stabilizing shell 201. The end of the stabilizing ring 203 away from the corrugated pipe 202 is wavy. Several balance wheels 208 are rotatably installed at the end of the stabilizing ring 203 away from the corrugated pipe 202. The balance wheels 208 are located at the crests of the wavy shape of the stabilizing ring 203 and are in contact with the outer surface of the wood being drilled, which reduces friction. When sucking up debris, outside air can enter from the troughs of the wavy shape on the stabilizing ring 203 and then be sucked away.

[0029] Please see Figure 5 , 6A blade 210 is fixedly welded to the inner end of the stabilizing shell 201, and the blade 210 is sleeved on the outer surface of the drill bit 102. A connector 209 is fixedly installed at the end of the blade 210 away from the connecting shaft 205, and the connector 209 is sleeved on the outer surface of the drill bit 102. Both the left and right ends of the connector 209 are rotatably installed with buckles 211. A slanted block is fixedly installed at the end of the buckle 211 near the drill bit 102. The slanted block is engaged in the groove on the outer surface of the drill bit 102. The outer surface of the stabilizing shell 201 has threaded holes, which correspond to the buckles 211 at the left and right ends of the connector 209. Stabilizing bolts 204 are threaded in the threaded holes. When the stabilizing bolts 204 rotate, they squeeze the buckles 211, thereby stabilizing the buckles 211.

[0030] Working principle:

[0031] During operation, the wood to be drilled is placed on the upper part of the base 1, and then the drive motor 101 is started. The output end of the drive motor 101 drives the drill bit 102 to rotate through the drive shaft 207. Then, the adjusting ring 4 is rotated to make the housing 5 move downward. Then the drill bit 102 opens to drill a hole in the wood. During the rotation of the drill bit 102, the blade 210 is driven to rotate through the buckle 211 and the connector 209, and an absorption force is generated. Then, under the action of the vacuum cleaner, the wood chips are absorbed into the vacuum cleaner, thereby reducing the effect of wood chips being raised.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
