Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically to a dustproof multi-axis drilling device. Background Technology

[0002] In construction projects, it is often necessary to drill holes in floor slabs to place reinforcing cages and allow them to be fitted with several steel bars at the ends of the cages. Since the structural dimensions of the reinforcing cages are prefabricated according to specifications, each hole needs to be precisely positioned and drilled sequentially. However, in actual construction, human measurement errors and operational errors often lead to deviations in the drilling positions. Even a single misaligned hole can prevent the placement of the reinforcing cage, requiring re-drilling or enlarging of existing holes, which is time-consuming and labor-intensive. In addition, drilling easily generates dust, causing pollution to the construction environment. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the present invention provides a dustproof multi-axis drilling device, which solves the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A dustproof multi-axis drilling device is provided, comprising a housing, a drive shaft and several driven shafts located around the drive shaft inside the housing, a drive gear on the drive shaft, and driven gears meshing with the drive gears on the driven shafts, the front ends of the several driven shafts extending out from the front end of the housing and respectively fixedly connected to several drill chucks, a bellows on the front end of the housing, and several drill chucks are fitted around the bellows with gaps, and an adjustment mechanism for adjusting the extension and retraction of the bellows is provided on the housing.

[0006] Furthermore, the adjustment mechanism includes cylinders disposed on both sides of the housing, a lead screw disposed inside the cylinder, a sliding block fitted on the lead screw, a connecting rod slidably passing through the sliding block, an abutment disposed at the rear end of the connecting rod, a tension spring sleeved on the connecting rod, and the two ends of the tension spring being connected to the abutment and the sliding block respectively, and the front end of the connecting rod passing through the cylinder and connecting to the front end of the bellows.

[0007] Furthermore, a first bevel gear is provided at the rear end of the lead screw, a rotating shaft is provided on the outer side of the cylinder, a second bevel gear that meshes with the first bevel gear is provided on the inner end of the rotating shaft, and a turntable is provided on the outer end of the rotating shaft.

[0008] Furthermore, several driven shafts are arranged in a matrix, and several driving gears are provided on the driving shaft. Each driving gear meshes only with several driven gears on several driven shafts that are equidistant from the driving shaft.

[0009] Furthermore, the rear end of the drive shaft is connected to an external rotating device for transmission.

[0010] Furthermore, the corrugated pipe is transparent.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This solution uses a drive shaft to drive several driven shafts to rotate synchronously. Each driven shaft can have a drill bit installed at its front end via a drill chuck, allowing several drill bits to drill synchronously, greatly improving drilling efficiency and ensuring precise positioning of each drill hole for easy insertion and connection with the end of the reinforcing cage.

[0013] 2. This solution uses a bellows to cover the dust generated during drilling. The bellows can be extended or retracted by an adjustment mechanism to accommodate drill bits of different lengths. Specifically, by rotating the lead screw, the sliding block can be moved axially, which in turn moves the connecting rod axially and drives the bellows to extend or retract.

[0014] 3. This solution uses a tension spring to achieve an elastic connection between the connecting rod and the sliding block. As the drill bit penetrates deeper into the hole, the connecting rod can slide on the sliding block, causing the tension spring to extend and thus driving the bellows to automatically contract. When the drill bit is pulled out of the hole, the bellows can automatically extend under the action of the tension spring, ensuring that the front end of the bellows is always in contact with the board surface, thereby achieving a good dustproof effect.

[0018] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0019] like Figure 1 and Figure 2 As shown, the dustproof multi-axis drilling device of this solution includes a housing 1. Inside the housing 1, there is a drive shaft 2 and six driven shafts 3 located around the drive shaft 2. The rear end of the drive shaft 2 is connected to an external rotating device for transmission. Two drive gears 4 are installed on the drive shaft 2. The six driven shafts 3 are arranged in a matrix. The four driven shafts 3 located at the four corners are respectively meshed with one of the drive gears 4 through four driven gears 5. The other two driven shafts 3 are respectively meshed with another drive gear 4 through two driven gears 5. The front ends of the six driven shafts 3 pass through the front end of the housing 1 and are respectively fixedly connected to six drill chucks 6. The drill chucks 6 are used to install drill bits. Their structure is a conventional structure in the prior art, so it will not be described in detail.

[0020] This solution uses the drive shaft 2 to drive six driven shafts 3 arranged in a matrix to rotate synchronously, thereby enabling the six drill bits to drill synchronously, which greatly improves drilling efficiency. At the same time, the position of each drill hole is accurately positioned to facilitate the end socketing and fitting with the reinforcing cage.

[0021] The front end of the housing 1 is provided with a bellows 7, and six drill chucks 6 are fitted between the bellows 7. The bellows 7 is transparent. The housing 1 is provided with an adjustment mechanism for adjusting the extension and retraction of the bellows 7. The adjustment mechanism includes a cylinder 8 provided on both sides of the housing 1. A lead screw 9 is provided inside the cylinder 8. A sliding block 10 is fitted on the lead screw 9. A connecting rod 11 is slidably passed through the sliding block 10. An abutment 12 is provided at the rear end of the connecting rod 11. A tension spring 13 is fitted on the connecting rod 11. The two ends of the tension spring 13 are respectively connected to the abutment 12 and the sliding block 10. The front end of the connecting rod 11 passes through the cylinder 8 and is connected to the front end of the bellows 7.

[0022] This solution uses a corrugated pipe 7 to cover the dust generated during drilling. The corrugated pipe 7 can be adjusted in length and width by an adjustment mechanism to accommodate drill bits of different lengths. Specifically, by rotating the lead screw 9, the sliding block 10 can be moved axially, thereby moving the connecting rod 11 axially and causing the corrugated pipe 7 to extend or retract. At the same time, the tension spring 13 enables the connecting rod 11 to be elastically connected to the sliding block 10. As the drill bit penetrates the hole, the connecting rod 11 can slide on the sliding block 10, causing the tension spring 13 to extend, thereby causing the corrugated pipe 7 to automatically retract. When the drill bit is pulled out of the hole, the corrugated pipe 7 can automatically extend under the action of the tension spring 13, so that the front end of the corrugated pipe 7 is always in contact with the plate surface, thus enabling the corrugated pipe 7 to achieve a good dustproof effect.

[0023] As an optional implementation, a first bevel gear 14 is provided at the rear end of the lead screw 9, a rotating shaft is provided on the outer side of the cylinder 8, a second bevel gear 15 that meshes with the first bevel gear 14 is provided on the inner end of the rotating shaft, and a turntable 16 is provided on the outer end of the rotating shaft, and the lead screw 9 can be driven to rotate by rotating the turntable 16.
