Description

Technical Field

[0001] This application relates to the technical field of machining equipment, and in particular to a drilling and tapping device. Background Technology

[0002] A drilling machine typically includes a worktable and a drill bit mounted on a frame. The drill bit is rotatably mounted on the frame and located above the worktable. When machining a workpiece, the workpiece is fixed on the worktable, and the drill bit above the worktable is driven to rotate and make axial feed motion downward, thereby enabling the drill bit to drill holes in the workpiece.

[0003] After drilling, the workpiece still needs to have threads machined on the inner surface of the hole, which is usually done by a tapping machine. A tapping machine is a mechanical processing equipment that processes internal threads, screws, or threads on the inner surface of holes in various parts such as machine housings, equipment end faces, nuts, and flanges with different specifications of through holes or blind holes.

[0004] In existing technologies, the workpiece is usually placed on a drilling machine to complete the drilling. After the workpiece is removed from the drilling machine, it is placed on a tapping machine to process the internal thread on the inner side of the hole using a tap. This requires multiple disassembly and assembly of the workpiece and handling of the workpiece, which is labor-intensive and has low work efficiency. Utility Model Content

[0005] In order to reduce labor costs and improve work efficiency during the drilling and internal threading of workpieces, this application provides a drilling and tapping device.

[0006] This application provides a drilling and tapping device, which adopts the following technical solution: it includes a frame, on which a worktable for fixing a workpiece is provided, the worktable part is used to adjust the position of the workpiece, and a working head is provided on the frame. The working head includes a drilling working head for drilling holes in the workpiece and a tapping working head for tapping the workpiece. The frame is also provided with a lifting power component for driving the working head closer to the worktable.

[0007] By adopting the above technical solution, the lifting power component drives the working head to approach the worktable and adjust the workpiece position in conjunction with the worktable, thereby achieving seamless switching between the two processing methods. This reduces the time cost of intermediate conversion waiting period, reduces labor costs, improves processing efficiency, and reduces equipment space occupation.

[0008] Preferably, the workbench is provided with at least two mounting arms, one end of which is used to connect to the lifting power component, and the other end of which is used to connect to the working head. Multiple mounting arms are arranged at intervals along the circumference of the workbench.

[0009] By adopting the above technical solution, multiple mounting arms can be equipped with multiple working heads, allowing multiple workpieces to be processed simultaneously.

[0010] Preferably, the mounting arm has a through-hole, the length direction of which is parallel to the length direction of the mounting arm. The working head passes through the through-hole, and a cutting tool is connected to one end of the working head near the worktable. The cutting tool includes a drilling cutter and a tapping tap. The drilling cutter and the drilling working head correspond one-to-one, and the tapping tap and the tapping working head correspond one-to-one. The working head is reciprocatingly slidably connected to the mounting arm along the length direction of the through-hole.

[0011] By adopting the above technical solution, the reciprocating sliding of the working head along the length of the waist-shaped hole allows the tool to be adapted to the machining of workpieces of different sizes.

[0012] Preferably, the frame is provided with a mounting bracket, the top of the mounting bracket is connected to a lifting power component, the lifting power component drives the mounting bracket to slide back and forth towards or away from the worktable, the bottom of the mounting bracket is used to mount the mounting arm, and the mounting arm is rotatably connected to the mounting bracket with the connection point with the mounting bracket as the rotation point.

[0013] By adopting the above technical solution, the mounting arm and the mounting frame are rotatably connected, and the positional deviation of the working head relative to the workpiece can be precisely controlled by finely adjusting the angle of the mounting arm and tightening the adjusting nut.

[0014] Preferably, the mounting bracket is provided with adjusting bolts, and each adjusting bolt corresponds to a mounting arm. After passing through the mounting bracket and the oblong hole in sequence, the adjusting bolt is fitted with an adjusting nut. The adjusting nut and the adjusting bolt are threaded together. The adjusting nut is used to abut against the side of the mounting arm away from the mounting bracket, and the head of the adjusting bolt abuts against the top of the mounting bracket.

[0015] By adopting the above technical solution, and utilizing the cooperation of adjusting bolts and adjusting nuts, the mounting arm can rotate freely within a certain range and be locked at any angle, thereby achieving the requirement for precise positioning of the working head.

[0016] Preferably, the mounting bracket is further provided with a clamping assembly, which includes a clamping head and a clamping block. The clamping head passes through the waist-shaped hole and is reciprocally slidably connected to the mounting arm along the length direction of the waist-shaped hole. The clamping block is disposed at the bottom of the clamping head and is used to abut against the workpiece placed on the worktable.

[0017] By adopting the above technical solution, the clamping block and the worktable work together to achieve reliable clamping of the workpiece, and the clamping head can be positioned and reciprocated along the length of the waist-shaped hole, so that the clamping block can be adapted to workpieces of different sizes.

[0018] Preferably, the outer wall of the portion of the clamping head that passes through the waist-shaped hole near the clamping block is provided with an adjusting thread, and the clamping block is sleeved on the clamping head and the clamping block is threadedly connected to the clamping head.

[0019] By adopting the above technical solution, the threaded connection between the clamping head and the clamping block not only allows for easy adjustment of the clamping depth but also ensures the safety and reliability of the clamping process. Furthermore, it allows the clamping block to move along the axial direction of the clamping head, thereby adapting to workpieces of different thicknesses and reliably clamping them.

[0020] Preferably, the worktable includes a slide and a worktable plate. The slide is disposed on the frame, and the worktable plate is disposed on top of the slide. The slide drives the worktable plate to slide back and forth and is connected to the frame. The worktable plate is provided with at least two positioning posts for being embedded in the workpiece.

[0021] By adopting the above technical solution, with the help of the coordinated operation of the slide table and the worktable, and the accurate positioning by the positioning column, the inconvenience caused by the traditional manual handling mode is greatly improved, and the automation level of the entire process is enhanced.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The lifting power component drives the working head to approach the worktable and adjust the workpiece position in conjunction with the worktable, thereby achieving seamless switching between the two processing methods. This reduces the time cost of waiting for intermediate conversion, reduces labor costs, improves processing efficiency, and reduces the space occupied by the equipment.

[0024] 2. By using the adjustment bolt and adjustment nut, the mounting arm can rotate freely within a certain range and be locked at any angle, thereby achieving the requirement of precise positioning of the working head. Attached Figure Description

Detailed Implementation

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a drilling and tapping device for reducing labor costs and improving work efficiency during the drilling and internal threading of workpieces.

[0032] refer to Figures 1-4 A drilling and tapping device includes a frame 110, on which a working head 130, a lifting power component 111, and a worktable 120 for fixing workpieces are mounted. The worktable 120 is used to adjust the position of the workpiece. In this embodiment, the worktable 120 includes a slide 121 and a worktable plate 122. The slide 121 is mounted on the frame 110, and the worktable plate 122 is mounted on top of the slide 121. The slide 121 drives the worktable plate 122 to slide back and forth and connect to the frame 110. At least two positioning posts 123 are mounted on the worktable plate 122. The positioning posts 123 are used to be embedded in the workpiece. With the cooperation of the slide 121 and the worktable plate 122, and the accurate positioning by the positioning posts 123, the inconvenience caused by the traditional manual handling mode is greatly improved, and the automation level of the entire process is enhanced.

[0033] The working head 130 includes a drilling working head 131 for drilling holes in the workpiece and a tapping working head 132 for tapping the workpiece. The lifting power component 111 is used to drive the working head 130 closer to the worktable 120. The lifting power component 111 can be a hydraulic cylinder or a pneumatic piston or other power source. The lifting power component 111 drives the working head 130 closer to the worktable 120 to adjust the position of the workpiece in coordination with the worktable 120, thereby realizing seamless switching between the two processing methods, reducing the time cost of intermediate conversion waiting period, reducing labor costs, improving processing efficiency and reducing equipment space occupation.

[0034] Specifically, a mounting frame 112 is provided on the frame 110. The top of the mounting frame 112 is connected to the lifting power component 111. The lifting power component 111 drives the mounting frame 112 to slide back and forth towards or away from the worktable 120. Furthermore, at least two mounting arms 140 are provided on the worktable 120. The bottom of the mounting frame 112 is used to mount the mounting arms 140. One end of the mounting arm 140 is used to connect to the mounting frame 112, and the mounting arm 140 is rotatably connected to the mounting frame 112 with the connection point with the mounting frame 112 as the rotation point. The other end of the mounting arm 140 is used to connect to the working head 130. Multiple mounting arms 140 are spaced apart around the circumference of the worktable 120. The shape of each mounting arm 140 evenly arranged along the circular track is like the spokes of a wheel extending radially around the center point. Through the distributed mounting arm 140 design, the space utilization and flexibility of the device can be effectively improved, meeting the processing needs under various complex working conditions.

[0035] More specifically, a waist-shaped hole 141 is passed through the mounting arm 140, and the length direction of the waist-shaped hole 141 is parallel to the length direction of the mounting arm 140. The working head 130 is inserted into the waist-shaped hole 141. A cutting tool 150 is connected to one end of the working head 130 near the worktable 120. The cutting tool 150 includes a drilling cutter 151 and a tapping tap 152. The drilling cutter 151 and the drilling working head 131 correspond one-to-one, and the tapping tap 152 and the tapping working head 132 correspond one-to-one. The working head 130 is reciprocatingly slidably connected to the mounting arm 140 along the length direction of the waist-shaped hole 141. In this embodiment, a fixing nut 133 is fitted on each working head 130. After the working head 130 is adjusted to a suitable position along the length direction of the waist-shaped hole 141, the fixing nut 133 is tightened so that the fixing nut 133 abuts against the bottom wall of the mounting arm 140.

[0036] Adjusting bolts 142 are installed on the mounting bracket 112. Each adjusting bolt 142 corresponds to a mounting arm 140. After passing through the mounting bracket 112 and the oblong hole 141, the adjusting bolt 142 is fitted with an adjusting nut 143. The adjusting nut 143 and the adjusting bolt 142 are threaded together. The adjusting nut 143 is used to abut against the side of the mounting arm 140 away from the mounting bracket 112. The head of the adjusting bolt 142 abuts against the top of the mounting bracket 112. By using the cooperation of the adjusting bolt 142 and the adjusting nut 143, the mounting arm 140 can rotate freely within a certain range and lock at any angle, thereby accurately controlling the positional deviation of the working head 130 relative to the workpiece and achieving the requirement of precise positioning of the working head 130.

[0037] In addition, to improve stability during machining, a clamping assembly 160 is provided on the mounting bracket 112. The clamping assembly 160 includes a clamping head 161 and a clamping block 162. The clamping head 161 passes through the oblong hole 141 and is reciprocally slidably connected to the mounting arm 140 along the length of the oblong hole 141. The clamping block 162 is located at the bottom of the clamping head 161 and is used to abut against the workpiece placed on the worktable 120. One end of the clamping head 161 near the clamping block 162 passes through a portion of the outer wall of the oblong hole 141. An adjusting thread 163 is provided. The clamping block 162 is sleeved on the clamping head 161 and threadedly connected to the clamping head 161. Through the threaded connection between the clamping head 161 and the clamping block 162, the clamping depth can be easily adjusted, the safety and reliability of the clamping process can be ensured, and the clamping block 162 can move axially along the clamping head 161 to adapt to workpieces of different thicknesses and clamp them reliably. The reciprocating sliding of the clamping head 161 along the length direction of the waist-shaped hole 141 allows the clamping block 162 to adapt to workpieces of different sizes.

[0038] The implementation principle of the drilling and tapping device in this application embodiment is as follows: the lifting power component 111 drives the working head 130 to approach the worktable 120 to cooperate with the worktable 120 to adjust the position of the workpiece, thereby realizing the seamless switching between the two processing methods, reducing the time cost of intermediate conversion waiting period, reducing labor costs, improving processing efficiency and reducing equipment space occupation.

[0039] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
