Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, and more specifically, to a processing device for flange tapping. Background Technology

[0002] A flange, also called a flange plate or flange, is a component used to connect pipes to each other, for connecting the pipe ends; flanges are also used on equipment inlets and outlets to connect two pieces of equipment, such as speed reducer flanges. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolts connected together as a combined sealing structure.

[0003] Tapping is required during flange processing to install bolts. Chinese patent CN 219189425 U discloses a "Drilling and Tapping Device for Processing Flange End Plates." The drawback of this patent is that because the flange has multiple threaded holes arranged in a circumferential pattern, each threaded hole needs to be tapped individually. Furthermore, since the flange is fixed between the fan-shaped support plate 9 and the limiting ring 4, processing each flange requires multiple rotations of the handle to tap multiple flanges at different locations. This complex operation reduces tapping efficiency, which is a deficiency of the existing technology. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a processing device for flange tapping.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a processing device for tapping flanges, including a base, a bracket, a bearing plate, a power mechanism, a handle and a tapping head. The bearing plate is provided with a rotating mechanism, which includes a rotating support plate for supporting the flange to be processed, and a fixing mechanism for fixing the flange is provided on the rotating support plate.

[0006] A further improvement of this utility model is that the rotating mechanism also includes a motor, a gear, and a gear ring. The output shaft of the motor is connected to the gear, the gear meshes with the gear ring, the upper part of the gear ring is fixed to the rotating support disk, and a support shaft is rotatably arranged inside the gear ring, which is fixedly connected to the bearing disk.

[0007] A further improvement of this utility model is that the fixing mechanism includes a set of fixing plates arranged along the circumferential direction, the fixing plates are connected to the piston rod of the fixing cylinder, and the fixing cylinder is fixedly connected to the rotating support plate.

[0008] A further improvement of this utility model is that the two ends of the fixed cylinder are respectively fixed to the "L"-shaped support plate, and the "L"-shaped support plate is fixed to the rotating support disk.

[0009] A further improvement of this utility model is that the shape of the fixing plate is arc-shaped.

[0010] A further improvement of this utility model is that a positioning mechanism is provided on the rotating support plate, the positioning mechanism including a positioning ring, the positioning ring being sleeved on the outer surface of the flange.

[0011] A further improvement of this utility model is that a guide ramp is provided at the top of the inner wall of the positioning ring.

[0012] A further improvement of this utility model is that the handle is connected to the drive mechanism, the drive mechanism includes a vertically arranged pneumatic cylinder, one end of the pneumatic cylinder is fixed to the spindle box through a mounting plate, and the piston rod of the pneumatic cylinder is fixed to a connecting sleeve, which is sleeved on the handle.

[0013] The beneficial effects of this utility model are as follows: This application provides a rotating mechanism on the bearing plate. During the tapping process, this rotating mechanism can drive the flange to rotate. When multiple threaded holes on the flange need to be tapped, the tapping head can remain stationary, and the tapping process for multiple threaded holes can be completed simply by rotating the flange through the rotating mechanism. This application uses a fixing mechanism to fix the flange, ensuring the stability and safety of the flange during the tapping process and avoiding the impact of displacement or shaking on machining accuracy. A drive mechanism is used to move the handle, conveniently controlling the up and down movement of the tapping head to achieve tapping. The rotating mechanism, fixing mechanism, and drive mechanism work together to make the entire tapping device simpler to operate, achieves higher machining accuracy, and improves the processing efficiency and flexibility of the device.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0021] like Figure 1-5 As shown, a processing device for tapping flanges includes a base 1, a bracket 2, a bearing plate 3, a power mechanism 4, a handle 5, and a tapping head 6. A rotating mechanism 7 is provided on the bearing plate. The rotating mechanism 7 includes a rotating support plate 71 for supporting the flange 10 to be processed. A fixing mechanism 8 for fixing the flange 10 is provided on the rotating support plate 71.

[0022] Since the tapping device is existing technology, and its structure and working principle have been disclosed in detail in patent CN 219189425 U, the applicant will not describe the specific structure and working principle of the tapping device in detail here.

[0023] This application provides a rotating mechanism 7 on the bearing plate 3. During the tapping process, the rotating mechanism 7 can drive the flange to rotate. When multiple threaded holes on the flange need to be tapped, the tapping head 6 can be kept stationary, and the tapping process of multiple threaded holes can be completed simply by driving the flange to rotate through the rotating mechanism 7.

[0024] Furthermore, the rotating mechanism 7 also includes a motor 73, a gear 72, and a gear ring 74. The output shaft of the motor 73 is connected to the gear 72, and the gear 72 meshes with the gear ring 74. The upper part of the gear ring 74 is fixed to the rotating support disk 71. A support shaft 75 is rotatably disposed inside the gear ring 74, and this support shaft is fixedly connected to the bearing disk. The main shaft of the motor 73 drives the gear 72 to rotate, the gear 72 drives the gear ring 74 to rotate, the gear ring 74 drives the rotating support disk 71 to rotate, and the flange located on the rotating support plate will also rotate accordingly.

[0025] Furthermore, the flange needs to be fixed by a fixing mechanism 8, which includes a set of fixing plates 83 arranged circumferentially. The fixing plates 83 are connected to the piston rod of the fixing cylinder 81, and the fixing cylinder 81 is fixedly connected to the rotating support plate 71. The fixing plates 83 clamp or loosen the flange by extending or retracting the fixing cylinder 81.

[0026] Furthermore, the two ends of the fixed cylinder 81 are respectively fixed to the "L"-shaped support plate 82, and the "L"-shaped support plate 82 is fixed to the rotating support disk 71.

[0027] Furthermore, the fixing plate 83 is arc-shaped. The arc design conforms to the shape characteristics of the flange, allowing the fixing plate 83 to fit more closely to the flange and distribute the clamping force more evenly.

[0028] To ensure the flange is positioned on the rotating support plate 71, a positioning mechanism is provided on the rotating support plate 71. The positioning mechanism includes a positioning ring 11, which is fitted onto the outer surface of the flange. Placing the flange inside the positioning ring 11 achieves initial positioning of the flange, and then the fixing mechanism 8 is used to fix the flange.

[0029] Furthermore, a guide ramp 111 is provided at the top of the inner wall of the positioning ring 11. The guide ramp 111 plays a certain guiding role in the placement direction of the flange, ensuring that the flange can be accurately fitted into the positioning ring 11, thereby improving the accuracy and efficiency of the processing.

[0030] To further improve the efficiency of tapping, this invention also includes a drive mechanism 9, which comprises a vertically arranged pneumatic cylinder 91. One end of the pneumatic cylinder 91 is fixed to the spindle box via a mounting plate 92. The piston rod of the pneumatic cylinder 91 is fixed to a connecting sleeve 93, which is fitted onto the handle. When the piston rod of the pneumatic cylinder 91 extends, it can drive the handle downward to achieve tapping; when the piston rod of the pneumatic cylinder 91 retracts, it can drive the handle upward to lift the tapping head out of the threaded hole.
