Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bench drills, in particular to a bench drill device with a drilling positioning and guiding structure. Background Technique
[0002] A bench drill, abbreviated as a table drill, is a small hole processing machine tool with a small volume and simple operation, usually installed on a special workbench. When the bench drill is drilling, a guiding structure is usually not installed, and the vertical position of the drill bit descending is controlled by a vertical lifting arm.
[0003] When the existing bench drill device is in use, the perpendicularity of the drill bit descending is controlled by the vertical movement of the lifting arm. After the device is aged and the joints are loosened during long-term use, the telescopic movement of the lifting arm may have a small inclination, resulting in a deviation in the drilling position.
[0004] Therefore, in view of the situation that the drilling position of the above bench drill device is prone to deviation after long-term use, a drilling positioning and guiding structure can be designed to guide the drill bit to ensure that the drill bit can vertically descend for drilling. Content of the Utility Model
[0005] In order to overcome the problem that when the existing bench drill device is in use, there is no guiding structure for the drill bit, and the perpendicularity of the drill bit descending is controlled by the vertical movement of the lifting arm. After the device is aged and the joints are loosened during long-term use, the telescopic movement of the lifting arm may have a small inclination, resulting in a deviation in the drilling position.
[0006] The technical solution of the utility model is: a bench drill device with a drilling positioning and guiding structure, including a bench drill body; further including a guiding component. A bottom plate is arranged on the right side of the bench drill body. Pillars are arranged at the corners of the upper surface of the bottom plate. The top surface of the pillar is provided with a top plate. One end of a screw rod is rotatably connected to the rear side position of the bottom surface of the top plate. The upper side of the outer surface of the screw rod is provided with a first moving seat. The left side surface of the first moving seat is provided with a first connecting rod. The left end of the first connecting rod is connected to a support plate. A through groove is opened on the upper surface of the support plate. A guiding component is arranged on the upper surface of the support plate. The guiding component includes a base, a limiting seat, a limiting groove and a limiting block; Three limiting seats are arranged on the upper surface of the support plate. A limiting seat is arranged above the limiting seat. A limiting groove is opened on the inner surface of the limiting seat. A limiting block is arranged on the outer surface of the drill bit seat of the bench drill body. The limiting block is matched with the limiting groove.
[0007] Preferably, by setting the guiding component, during the downward pressing of the drill bit, it will penetrate into the interior of the limit seat. At this time, the limit block on the outer surface of the drill bit seat will insert into the limit groove for sliding. The cooperation between the limit block and the limit groove can play a guiding role for the drill bit, reducing the deviation during drilling, thereby solving the problem that the existing bench drill equipment does not have a guiding structure for the position of the drill bit during use, and only relies on the lifting arm for positioning, resulting in easy deviation of the drilling position during use.
[0008] Preferably, the through groove is arc-shaped, and the concentricity of the through groove with the lifting arm of the bench drill body is consistent. By setting the arc-shaped through groove and arranging the base along the through groove, after the drill bit adjusts its angle, its position will still correspond to the position of the through groove, ensuring that it can correspond to the bases on both sides, thereby improving the equipment accuracy.
[0009] Preferably, the inner surface of the base is provided with internal threads, and the lower end of the outer surface of the limit seat is provided with external threads. The limit seat is threadedly connected to the base. By setting the internal threads and external threads, it is convenient for the staff to quickly disassemble and assemble the limit seat.
[0010] Preferably, a second moving seat is arranged at the lower position of the outer surface of the screw rod. A second connecting rod is installed on the left side surface of the second moving seat. A bracket is installed on the left end surface of the second connecting rod. A collection box is placed above the bracket. By setting the collection box, during drilling, the debris falling from the surface of the operating table will be collected by the collection box, and by setting the bracket, the collection box can be quickly disassembled and assembled, facilitating the staff to clean it.
[0011] Preferably, a driving motor is arranged at the rear side of the upper surface of the bottom plate, and the output end of the driving motor is connected to the bottom of the screw rod. By setting the driving motor, during operation, it will drive the screw rod to rotate, thereby driving the first moving seat and the second moving seat to lift synchronously, so as to adjust the interval between the support plate and the operating table of the bench drill body, thereby adapting to workpieces of different thicknesses.
[0012] Preferably, connecting rods are arranged on the front side surfaces of the first moving seat and the second moving seat. The front ends of the connecting rods are connected with slip rings. A slide rod is installed at the front side position of the upper surface of the bottom plate. The slip rings are slidably connected to the slide rod. By setting the slide rod, when the first moving seat and the second moving seat move, the slip rings will slide on the surface of the slide rod, improving the stability of the equipment operation, and by setting the connecting rods, it can play a limiting role for the first moving seat and the second moving seat, preventing the two from rotating synchronously with the screw rod.
[0013] Preferably, the first connecting rod is welded to the support plate, and the second connecting rod is welded to the bracket. By connecting the first connecting rod and the support plate and the second connecting rod and the bracket by welding, the overall strength of the connection points can be improved, avoiding damage during use.
[0014] Advantages of the utility model:
[0015] 1. By setting the guiding component, during the downward pressing of the drill bit, it will penetrate from the inside of the limit seat. At this time, the limit block on the outer surface of the drill bit seat will insert into the limit groove for sliding. The cooperation between the limit block and the limit groove can play a guiding role for the drill bit, reducing the deviation during drilling, thereby solving the problem that the existing bench drill equipment does not have a guiding structure for the drill bit position during use and only relies on the lifting arm for positioning, resulting in easy deviation of the drilling position during use;
[0016] 2. By setting the arc-shaped through groove and arranging the base along the through groove, after the drill bit adjusts the angle, its position will still correspond to the position of the through groove, ensuring correspondence with the bases on both sides, thereby improving the equipment accuracy. And by setting the internal thread and external thread, it is convenient for the staff to quickly disassemble and assemble the limit seat. Description of the drawings

A top plate 4 is installed on the top surface of the pillar 3. One end of a screw rod 5 is rotatably connected to the rear side position of the bottom surface of the top plate 4. A first moving seat 6 is arranged on the upper side of the outer surface of the screw rod 5. A first connecting rod 7 is installed on the left side surface of the first moving seat 6. The left end of the first connecting rod 7 is connected to a support plate 8. A through groove 9 is formed on the upper surface of the support plate 8. A guiding component is arranged on the upper surface of the support plate 8. The guiding component includes a base 101, a limiting seat 102, a limiting groove 103 and a limiting block 104.

A limiting groove 103 is formed on the inner surface of the limiting seat 102. A limiting block 104 is installed on the outer surface of the drill bit seat of the bench drill body 1. The limiting block 104 is matched with the limiting groove 103. By setting the guiding component, during the process of the drill bit pressing down, it will penetrate into the inside of the limiting seat 102. At this time, the limiting block 104 on the outer surface of the drill bit seat will be inserted into the limiting groove 103 for sliding. The cooperation between the limiting block 104 and the limiting groove 103 can play a guiding role for the drill bit and reduce the deviation during drilling.
[0025] Please refer to Figures 1-4 In this embodiment, the through groove 9 is arc-shaped, and the concentricity of the through groove 9 with the lifting arm of the bench drill body 1 is consistent. By setting the arc-shaped through groove 9, the base 101 is arranged along the through groove 9. After the drill bit adjusts the angle, its position will still correspond to the position of the through groove 9, ensuring that it can correspond to the bases 101 at both sides, thereby improving the equipment accuracy. An internal thread 12 is formed on the inner surface of the base 101, and an external thread 11 is formed at the lower end of the outer surface of the limiting seat 102. The limiting seat 102 is threadedly connected to the base 101.

[0026] Please refer to Figures 1-5, in this embodiment, a driving motor 20 is provided at the rear side of the upper surface of the bottom plate 2. The output end of the driving motor 20 is connected to the bottom of the screw rod 5. By setting the driving motor 20, the screw rod 5 will be driven to rotate during operation, thereby driving the first moving seat 6 and the second moving seat 13 to lift synchronously, so as to adjust the interval between the support plate 8 and the working table of the bench drill body 1, so as to adapt to workpieces of different thicknesses.

By setting the slide bar 19, when the first moving seat 6 and the second moving seat 13 move, the slip ring 18 will slide on the surface of the slide bar 19, improving the stability of the equipment operation. And by setting the connecting rod 17, the first moving seat 6 and the second moving seat 13 can be limited, preventing the two from rotating synchronously with the screw rod 5. The first connecting rod 7 is welded to the support plate 8, and the second connecting rod 14 is welded to the support 15. By connecting the first connecting rod 7 and the support plate 8 and the second connecting rod 14 and the support 15 by welding, the overall strength of the connection points can be improved, avoiding damage during use.
[0027] During operation, by setting the arc-shaped through groove 9 and arranging the base 101 along the through groove 9, after the drill bit adjusts the angle, its position will still correspond to the position of the through groove 9, ensuring that it can correspond to the bases 101 at both sides, so as to improve the equipment accuracy. And by setting the internal thread 12 and the external thread 11, it is convenient for the staff to quickly disassemble and assemble the limit seat 102. And by setting the collection box 16, during drilling, the debris falling from the surface of the working table will be collected by the collection box 16. And by setting the support 15, the collection box 16 can be quickly disassembled and assembled, facilitating the staff to clean. And by setting the driving motor 20, the screw rod 5 will be driven to rotate during operation, thereby driving the first moving seat 6 and the second moving seat 13 to lift synchronously, so as to adjust the interval between the support plate 8 and the working table of the bench drill body 1, so as to adapt to workpieces of different thicknesses. And by setting the slide bar 19, when the first moving seat 6 and the second moving seat 13 move, the slip ring 18 will slide on the surface of the slide bar 19, improving the stability of the equipment operation. And by setting the connecting rod 17, the first moving seat 6 and the second moving seat 13 can be limited, preventing the two from rotating synchronously with the screw rod 5. And by connecting the first connecting rod 7 and the support plate 8 and the second connecting rod 14 and the support 15 by welding, the overall strength of the connection points can be improved, avoiding damage during use.
[0028] Through the above steps, by setting the guiding component, during the downward pressing of the drill bit, it will penetrate into the inside of the limit seat 102. At this time, the limit block 104 on the outer surface of the drill bit seat will be inserted into the limit groove 103 for sliding. The cooperation between the limit block 104 and the limit groove 103 can play a guiding role for the drill bit, reducing the deviation during drilling, thereby solving the problem that the existing bench drill equipment does not have a guiding structure for the position of the drill bit during use and only relies on the lifting arm for positioning, resulting in easy deviation of the drilling position during use.
