Description

Technical Field

[0001] This utility model relates to the field of thread processing equipment technology, specifically to a high-strength bolt tapping device. Background Technology

[0002] High-strength bolts are critical connecting components widely used in mechanical manufacturing, building structures, and bridge engineering. Various bolt tapping devices have emerged in the current technology. A common approach is to use a fixed workstation with a single machining head. Specifically, the operator first manually clamps the high-strength bolt to be processed onto a fixed fixture, then starts the equipment. The drive mechanism moves the drill bit or tap to perform drilling or tapping operations. After completing one process, it may be necessary to manually change the tool or transfer the bolt to another machine dedicated to the next process. The main problems with this fixed-station, single-machine processing method are low automation, reliance on manual loading and unloading, low efficiency, and certain safety hazards. Furthermore, the step-by-step processing requires the bolt to be clamped and positioned multiple times, which can easily lead to cumulative errors and affect processing accuracy.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a high-strength bolt tapping device. Through the coordinated design of a rotating worktable, an integrated tapping mechanism and an automatic loading and unloading mechanism, the device realizes the automated continuous processing of high-strength bolts. The drilling and tapping processes are completed in one clamping, which effectively improves processing efficiency and accuracy and reduces the risk of manual operation.

[0005] Technical Solution: This utility model provides a high-strength bolt tapping device, including a support frame, a table, a rotary worktable, a tapping mechanism, and a loading / unloading mechanism. The table is mounted on the support frame, and the rotary worktable is mounted on the table, including an upper turntable and a lower base plate. The lower base plate is fixedly mounted on the table, and the upper turntable is rotatably connected to the lower base plate, used to carry the high-strength bolts to be drilled and tapped and to drive them to rotate. The tapping mechanism is mounted on the table and located above the rotary worktable, used to perform drilling and tapping operations on the high-strength bolts. The loading / unloading mechanism is mounted on the table, used to transport the high-strength bolts to be drilled to the rotary worktable and to remove the finished parts after drilling and tapping from the rotary worktable. The lower chassis is fixed to the table to provide rigid support, while the upper turntable can rotate to achieve workstation switching. It accurately carries the bolts to be processed and positions them to the processing position. Drilling and tapping are completed in one operation above the rotating worktable without the need to change equipment or tools, reducing the time spent on process changeover. The loading and unloading mechanism enables accurate loading of bolts to be processed and automatic unloading of finished parts.

[0006] Furthermore, in this application, a high-strength bolt tapping device includes a lower chassis fixedly mounted on a table, an upper turntable and a lower chassis connected by a rotating shaft, and a stepper motor mounted on the lower chassis, the output end of which is connected to the rotating shaft. The stepper motor is rigidly connected to the upper turntable via the rotating shaft, allowing for precise adjustment of the working position spacing on the upper turntable.

[0007] Furthermore, in this application, a high-strength bolt tapping device is provided, wherein the upper turntable is divided into several working areas on its circumference, and each working area is provided with a first working position and a second working position. The first working position and the second working position are used to place and limit the high-strength bolt, and the upper turntable is rotated to directly below the tapping mechanism by a stepper motor.

[0008] Furthermore, this application discloses a high-strength bolt tapping device, wherein the tapping mechanism includes a drive motor, a transmission assembly, a drill bit, a tapping head, a hanging plate, a set of guide columns, and a cylinder. The hanging plate is parallel to the platform above the work surface, and the guide columns pass through the platform with their upper ends fixedly connected to the hanging plate. The cylinder is located below the platform and is used to drive the guide columns to reciprocate the hanging plate in the vertical direction. The drive motor is installed on the lower side of the hanging plate, and the transmission assembly is connected to the output end of the drive motor. The drill bit and the tapping head are connected to the transmission assembly. The drive motor drives the drill bit and the tapping head to rotate simultaneously through the transmission assembly. The drill bit faces the first working position, and the tapping head faces the second working position. After the upper turntable rotates into position, the drilling head is precisely aligned with the center of the bolt in the first working position, and the tapping head is precisely aligned with the center of the bolt in the second working position. When the hanging plate moves downward under the drive of the cylinder, the drilling head simultaneously drills the bolt in the first working position, and the tapping head simultaneously taps the already drilled bolt in the second working position, realizing the parallel execution of the two processes at the same time and in different working positions.

[0009] Furthermore, in this application, a high-strength bolt tapping device includes a loading and unloading mechanism comprising a robotic arm and a workpiece tray. The robotic arm and workpiece tray are mounted on a table. An array of high-strength bolts to be drilled is placed on the workpiece tray. The robotic arm is used to remove the finished part after drilling and tapping from the second working position and then grasp the high-strength bolts to be drilled from the workpiece tray onto the second working position. After the upper turntable rotates, the second working position becomes the first working position. When the upper turntable rotates to a position directly below the drill head, drilling is performed on the high-strength bolts to be drilled. The workpiece tray uses a grid-like positioning groove, which can hold 20-50 high-strength bolts to be processed in an array. Each positioning groove has a built-in elastic anti-slip pad to prevent the bolts from shaking or shifting during handling, ensuring the stability of the robotic arm's gripping.

[0010] Furthermore, in this application, a high-strength bolt tapping device includes an adjustment mechanism at both the first and second working positions. The adjustment mechanism comprises a movable clamping block, an L-shaped abutment, and an adjustment knob. Guide grooves are provided on the edges of both the first and second working positions, arranged radially along the upper turntable. The movable clamping block is slidably connected along the guide grooves and has a placement hole. The head diameter of the high-strength bolt is larger than the diameter of the placement hole, and the bolt shank extends into the placement hole. The L-shaped abutment is located on the outer edge of the upper turntable. The adjustment knob passes through the L-shaped abutment and the movable clamping block. By rotating the adjustment knob, the movable clamping block can be pushed to slide along the guide groove. Rotating the adjustment knob allows the drill bit and tapping head to be precisely aligned with the center of the bolt.

[0011] Furthermore, in this application, a high-strength bolt tapping device is provided, wherein the table surface is provided with a notch, and the loading and unloading mechanism further includes a parts bin located below the notch. When the robotic arm grabs the finished part after drilling and tapping, it moves to the top of the notch and releases it, after which the finished part after drilling and tapping falls into the parts bin.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. The high-strength bolt tapping device of this utility model achieves automated continuous processing of high-strength bolts through the coordinated design of a rotating worktable, an integrated tapping mechanism, and an automatic loading and unloading mechanism. Drilling and tapping processes can be completed in one clamping, which significantly improves processing efficiency, reduces manual operation, and lowers safety hazards.

[0013] 2. The high-strength bolt tapping device of this utility model ensures the precise positioning of the bolt through the adjustment mechanism. Combined with the precise control of the stepper motor, it guarantees the processing accuracy of drilling and tapping, avoids the cumulative error caused by multiple clamping, and the cooperation between the loading and unloading mechanism and the rotary worktable realizes assembly line operation, further improving production consistency.

Detailed Implementation

[0016] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1 like Figure 1 , Figure 2 and Figure 3 The high-strength bolt tapping device shown includes a support frame 1, a table 2, a rotary worktable 3, a tapping mechanism 4, and a loading / unloading mechanism 5. The table 2 is fixedly mounted on the support frame 1. The rotary worktable 3 is located at the center of the table 2 and includes an upper turntable 31 and a lower base plate 32. The lower base plate 32 is fixed to the table 2 with bolts. The upper turntable 31 is connected to the lower base plate 32 via a rotating shaft and can rotate relative to the lower base plate 32. A stepper motor 33 is mounted on the lower base plate 32, and the output end of the stepper motor 33 is connected to the rotating shaft to drive the upper turntable 31 to rotate.

[0018] In this embodiment, the upper turntable 31 is divided into six equal working areas 311 around its circumference. Each working area 311 is provided with a first working position 3111 and a second working position 3112, which are used to clamp high-strength bolts to be drilled and to be tapped, respectively. The stepper motor 33 drives the upper turntable 31 to rotate 30 degrees each time, so that each working area 311 passes through the processing position below the tapping mechanism 4 in sequence.

[0019] The tapping mechanism 4 includes a drive motor 41, a transmission assembly 42, a drill head 43, a tapping head 44, a hanging plate 45, a set of guide pillars 46, and a cylinder 47. The hanging plate 45 is arranged parallel above the table surface 2, and the guide pillars 46 pass through the table surface 2, with their upper ends fixedly connected to the hanging plate 45. The cylinder 47 is installed below the table surface 2, and its piston rod is connected to the lower end of the guide pillars 46, used to drive the hanging plate 45 to reciprocate vertically along the guide pillars 46. The drive motor 41 is fixed to the lower side of the hanging plate 45, and its output end drives the drill head 43 and the tapping head 44 to rotate simultaneously through the transmission assembly 42. The drill head 43 faces the first working position 3111, and the tapping head 44 faces the second working position 3112. When the cylinder 47 pushes the hanging plate 45 downward, the drilling head 43 drills holes in the bolts on the first working position 3111, and at the same time the tapping head 44 taps the bolts that have already been drilled on the second working position 3112.

[0020] The loading and unloading mechanism 5 includes a robot arm 51, a workpiece tray 52, and a parts bin 53. The workpiece tray 52 is placed on the table 2, on which multiple high-strength bolts to be processed are arranged in an array. The robot arm 51 is used to pick up the bolts to be processed from the workpiece tray 52 and place them on the second working position 3112. When the upper turntable 31 rotates 30 degrees, the original second working position 3112 becomes the first working position 3111. At the same time, the robot arm 51 removes the finished part that has been tapped from the current second working position 3112 and moves it to above the notch 21 on the table 2, placing the finished part into the parts bin 53 located below the notch 21.

[0021] Each working position is equipped with an adjustment mechanism 3113, including a movable clamping block 31131, an L-shaped stop block 31132, and an adjustment knob 31133. The movable clamping block 31131 slides along a radial guide groove 3114, and has a placement hole 311311 for placing bolts. By rotating the adjustment knob 31133, the movable clamping block 31131 can be moved along the guide groove 3114 to ensure that the drill bit 43 and the tapping bit 44 are aligned with the center of the bolt.

[0022] The workflow of this embodiment is as follows: The robot arm 51 first picks up the bolt to be processed on the workpiece tray 52 and places it in the second working position 3112; the stepper motor 33 drives the upper turntable 31 to rotate 30 degrees, so that the bolt moves into the first working position 3111, and at the same time, the robot arm 51 puts a new bolt into the vacated second working position 3112; the tapping mechanism 4 moves down, the drilling head 43 drills a hole in the bolt in the first working position 3111, and the tapping head 44 taps the bolt in the second working position 3112; after completion, the mechanism moves up, the upper turntable rotates 30 degrees again, the robot arm 51 removes the finished part and loads a new bolt, and the cycle continues.

[0023] The above embodiments are exemplary and are intended to illustrate the technical concept and features of this utility model, so that those skilled in the art can understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
