Description

Technical Field

[0001] This utility model belongs to the field of equipment and tooling, and relates to a drilling jig device, particularly a flange drilling jig device. Background Technology

[0002] In the field of drilling flange parts, traditional processes generally use single-station fixed drill jigs. Operators need to manually clamp the workpiece on the machine tool, tighten the flange with bolts and pressure plates, disassemble the finished product after machining, and repeat the clamping process.

[0003] This method has significant drawbacks: clamping time accounts for more than 60% of the entire operation cycle, and clamping a single piece takes 3-5 minutes, resulting in low equipment utilization. During the processing, personnel need to load and unload workpieces under the drill bit, which poses a safety hazard. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a flange clamping fixture to solve these problems.

[0005] The purpose of this utility model can be achieved through the following technical solution: a flange drilling jig device, including a base and a control system, characterized in that the base is provided with a worktable that can rotate 180° in the circumferential direction, and two workstations are symmetrically arranged at both ends of the worktable; A drive mechanism for rotating the worktable is connected below the worktable. Each workstation is equipped with a lifting platform, which is slidably connected to the workstation via multiple guide columns, and has a lifting cylinder at the bottom to drive its overall lifting. The lifting platform is equipped with a fastening mechanism, which includes a clamp for clamping the flange workpiece and a clamping cylinder for driving the clamp. A fixing frame is provided on one side of the base, on which a drill sleeve plate is installed. The central axis of the drill sleeve plate coincides with the central axis of the flange workpiece after it has been rotated into position. Both workstations are equipped with positioning sensors on their outer edges for rotating and positioning the workstations.

[0006] In the aforementioned flange drilling jig device, the driving mechanism can be a servo motor, whose output shaft is directly connected to the worktable rotation shaft.

[0007] In the aforementioned flange drilling jig device, there are four guide pillars, evenly distributed along the edge of the lifting platform, with the upper ends of the guide pillars penetrating the lifting platform.

[0008] In the aforementioned flange drilling jig device, the positioning sensor is a proximity switch, symmetrically positioned at both extreme positions of the worktable's rotation trajectory.

[0009] Compared with existing technologies, this flange drilling jig device is designed with a dual-station 180° rotating synchronous operation architecture. Through the combination of servo positioning, guide column stabilization and automatic clamping technology, it solves the problems of low efficiency, poor accuracy and high dependence on manual labor in traditional flange drilling equipment. It is particularly suitable for continuous processing scenarios of batch flange parts. Attached Figure Description

Detailed Implementation

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 As shown, this flange drilling jig device includes a base 1 and a control system. The base 1 has a worktable 2 that can rotate 180° circumferentially. Two workstations 3 are symmetrically arranged at both ends of the worktable 2. A drive mechanism 4 for rotating the worktable 2 is connected below it. Each workstation 3 has a lifting platform 5, which is slidably connected to the workstation 3 via multiple guide pillars 12. A lifting cylinder 6 is located at the bottom of the lifting platform 5 to drive its overall lifting. A fastening mechanism is provided on the lifting platform 5, including grippers 7 for clamping the flange workpiece and a clamping cylinder 8 for driving the grippers 7. A fixing frame 9 is provided on one side of the base 1, on which a drill sleeve plate 10 is mounted. The central axis of the drill sleeve plate 10 coincides with the central axis of the flange workpiece after rotation. Positioning sensors 11 are provided on the outer edges of both workstations 3 for positioning the worktable 2 during rotation. The drive mechanism 4 can be a servo motor, whose output shaft is directly connected to the rotating shaft of the worktable 2. Four guide pillars 12 are evenly distributed along the edge of the lifting platform 5, with the upper end of each guide pillar 12 penetrating the lifting platform 5. The positioning sensor 11 is a proximity switch, symmetrically positioned at both extreme points of the rotation trajectory of the workstation 3.

[0015] By designing a dual-station 180° rotating synchronous operation architecture, and through the combination of servo positioning, 12 guide column stabilization and automatic clamping technology, it solves the problems of low efficiency, poor accuracy and high dependence on manual labor in traditional flange drilling equipment, and is particularly suitable for continuous processing scenarios of batch flange parts.

[0016] Working principle When the drilling jig device is in operation, the operator first places the flange workpiece to be processed on the lifting platform 5 at one end of the worktable 2. At this time, the clamping cylinder 8 drives the gripper 7 to clamp and hold the workpiece, pressing and fixing it in the center of the lifting platform 5. The drive mechanism 4 then starts, driving the worktable 2 to rotate precisely 180°, so that the workstation 3 with the flange workpiece is rotated to directly below the fixed frame 9, while the idle workstation 3 at the other end is simultaneously rotated to the loading and unloading area.

[0017] During the rotation process, the positioning sensor 11 on the outer edge of the workstation 3 detects the position signal in real time to ensure that the central axis of the workpiece is completely aligned with the central axis of the drill sleeve plate 10 on the fixed frame 9.

[0018] After positioning, the lifting cylinder 6 pushes the lifting platform 5 to rise vertically along the four evenly distributed guide columns 12, pressing the flange workpiece into the drill sleeve of the drill sleeve plate 10, and completing the drilling process through the guidance of the drill sleeve.

[0019] While processing is underway, operators can disassemble completed workpieces and install new workpieces at the loading and unloading station.

[0020] When processing is completed, the lifting cylinder 6 drives the lifting platform 5 to move down and reset, and the worktable 2 rotates 180° again to exchange positions, entering a new round of operation cycle, realizing parallel operation of processing and loading / unloading.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
