Description

Technical Field

[0001] This utility model relates to the field of engine manufacturing technology, specifically to an engine cylinder milling device. Background Technology

[0002] The engine cylinder is one of the core components of an engine. Its structure, function, working principle, cylinder arrangement, and materials directly affect the engine's performance. The cylinder block is usually made of gray cast iron or aluminum alloy. The upper cylindrical cavity is the cylinder, and the lower part is the crankcase, which supports the crankshaft and provides space for the crankshaft to move. Inside the cylinder is a piston, which reciprocates under the pressure or expansion force of the working fluid.

[0003] In existing engine cylinder milling operations, jigs are typically used to hold the engine cylinder in place. However, this method only allows machining of the upper surface of the engine cylinder, leaving the surface close to the worktable inaccessible. This creates a machining obstacle, requiring the engine cylinder to be disassembled and rotated before machining can proceed. This process consumes significant time and effort, impacting machining efficiency. Therefore, we propose an engine cylinder milling device to address the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide an engine cylinder milling device to solve the problem mentioned in the background art that in the existing engine cylinder milling operation, the engine cylinder is usually fixed with a clamp. However, this fixing method can only process the upper surface of the engine cylinder. The surface of the engine cylinder close to the worktable is difficult to reach, which constitutes a processing obstacle and affects the processing. It is necessary to disassemble and reassemble the engine cylinder and flip it before processing. In this process, a lot of time and effort are consumed, which affects the processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A gear ring is fixedly connected to the outside of one of the rotating disks. A motor gear component is provided on one side of the gear ring.

[0007] The motor clamping component includes a motor mounting base, a clamping motor is fixedly mounted inside the motor mounting base, a rotating block is fixedly mounted at the output end of the clamping motor, and multiple pull rods are connected to the outer side of the rotating block by rotating evenly around an axis.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses two cylinder clamping components at both ends to push out two rotating disks, so that the motor clamping component clamps the engine cylinder.
