Description

Technical Field

[0001] This utility model relates to the field of cylinder end face machining technology, and in particular to a high-pressure cylinder end face machining mechanism. Background Technology

[0002] When producing high-pressure cylinders, the end faces of the high-pressure cylinders need to be machined. The traditional machining method is to place the operation above the milling machine. Because the high-pressure cylinder is large in size and has little contact surface with the machining platform, vibration will occur during machining, which seriously affects the product quality.

[0003] The prior art patent application with authorization publication number CN217372257U discloses a steam turbine cylinder processing support device, including a platform with T-shaped grooves equidistantly opened on the platform. A slider is nested in the T-shaped groove, and the slider has a connecting screw hole. A screw rod is threadedly connected to the connecting screw hole, and a threaded bushing is integrally connected to the top of the screw rod. This structure can easily support the steam turbine cylinder, effectively improve product quality, and reduce the impact of vibration on processing quality.

[0004] However, in the aforementioned prior art, the slider is embedded in the T-shaped groove, and then the hexagonal column is turned to drive the extension screw to rotate and move out. At this time, the support plate moves upward to support the bottom corner of the cylinder. However, the time required to fix the high-pressure cylinder during the entire clamping and fixing process is relatively long, which cannot be done quickly and affects the efficiency of end face processing. Utility Model Content

[0005] The purpose of this utility model is to provide a high-pressure cylinder end face processing mechanism, which aims to solve the problem that the existing technology takes a long time to fix the high-pressure cylinder, making it impossible to fix it quickly and affecting the efficiency of end face processing.

[0006] To achieve the above objectives, this utility model provides a high-pressure cylinder end face machining mechanism, including a milling machine body and a clamping unit. The clamping unit includes a mounting plate, a fixed box, a rotating plate, a track plate, a sliding plate, an arc plate, a connecting assembly, and a mounting assembly. The clamping unit is disposed above the milling machine body. The mounting plate is fixedly connected to the milling machine body and located on the inner side wall of the milling machine body. The fixed box is fixedly connected to the mounting plate and located above the mounting plate. The rotating plate is disposed on the inner side wall of the fixed box. The track plate is fixedly connected to the fixed box and located on the inner top wall of the fixed box. The fixed box has a sliding hole that slides with the arc plate. The sliding plate is slidably connected to the track plate and located on the inner side wall of the track plate. The arc plate is fixedly connected to the sliding plate and located above the sliding plate. The mounting assembly is connected to the rotating plate and the fixed box respectively. The connecting assembly is connected to the sliding plate and the rotating plate respectively.

[0007] The connecting assembly includes a connecting rod, a first circular shaft, and a second circular shaft. The first circular shaft is fixedly connected to the slide plate and is located below the slide plate. The second circular shaft is fixedly connected to the rotating plate and is located above the rotating plate. One end of the connecting rod is rotatably connected to the first circular shaft and is located on the outer side wall of the first circular shaft. The other end of the connecting rod is rotatably connected to the second circular shaft and is located on the outer side wall of the second circular shaft.

[0008] The connecting assembly further includes a bottom plate and a top plate. The bottom plate is fixedly connected to the first circular shaft and is located below the first circular shaft. The top plate is fixedly connected to the second circular shaft and is located on the outer side wall of the second circular shaft.

[0009] The mounting assembly includes a connecting shaft, a coupling, and a motor frame. The connecting shaft is fixedly connected to the rotating plate and located below the rotating plate. The coupling is detachably connected to the connecting shaft and located on the outer side wall of the connecting shaft. The motor frame is fixedly connected to the fixed box and located on the inner bottom wall of the fixed box.

[0010] The mounting assembly further includes a reinforcing rib, one end of which is fixedly connected to the connecting shaft and located on the outer side wall of the connecting shaft, and the other end of which is fixedly connected to the rotating plate and located below the rotating plate.

[0011] This utility model discloses a high-pressure cylinder end face processing mechanism. In use, the mounting plate is first placed above the milling machine body, and then the high-pressure cylinder is placed on the fixed box. The stepper motor is fixed by the mounting assembly, which drives the rotating plate to rotate. At this time, the connecting assembly pulls the sliding plate towards the high-pressure cylinder until the arc plate clamps the high-pressure cylinder. By fixing the high-pressure cylinder in this way, the installation time is not too long, which affects the efficiency of end face processing, and the workload of workers can be effectively reduced.

[0020] This utility model provides a high-pressure cylinder end face machining mechanism, including a milling machine body 101 and a clamping unit. The clamping unit includes a mounting plate 102, a fixed box 103, a rotating plate 104, a track plate 105, a sliding plate 106, an arc plate 107, a connecting assembly, and a mounting assembly.

[0022] In this embodiment, the mounting plate 102 is first placed above the milling machine body 101, and then the high-pressure cylinder is placed on the fixed box 103. The stepper motor 118 is fixed by the mounting assembly, which drives the rotating plate 104 to rotate. At this time, the connecting assembly pulls the sliding plate 106 towards the high-pressure cylinder until the arc plate 107 clamps the high-pressure cylinder. Fixing the high-pressure cylinder in this way avoids the installation time being too long and affecting the efficiency of end face processing, and can effectively reduce the workload of workers.
