Embodiment 1

[0036] Such as figure 1As shown, a cylinder shell air release groove processing device includes a push drive part 1, a push shaft 2, a fixing part 3 and several pressure groove parts 4, and the push drive part 1 is a hydraulic cylinder or an air cylinder or a push rod motor. The push shaft 2 and the fixed part 3 are slidingly connected along the axial direction of the push shaft 2, and the driving part 1 is pushed to drive the fixed part 3 to slide. Part 3 is slidingly connected, and the sliding direction of pressure groove part 4 is away from the axis of push shaft 2. On the outer wall of pressure groove part 4, there are several pressure groove convex teeth 4.1, and several pressure groove convex teeth 4.1 are arranged along the push shaft 2. The axis of the groove is evenly arranged in the circumferential direction, the inner side wall of the pressure groove part 4 is in contact with the push shaft 2, and the side wall of the push shaft 2 in contact with the pressure groove...

Embodiment 2

[0039] Such as figure 1 As shown, on the basis of Embodiment 1, the pressure groove member 4 includes several pressure blocks 4.2 arranged along the axial direction of the push shaft 2, and several pressure blocks 4.2 are respectively slidably connected with the fixing member 3, and the pressure groove convex teeth 4.1 is arranged on the outer side wall of the pressure block 4.2. The sliding direction of the pressure block 4.2 is inclined to one side of the axial direction of the push shaft 2, and the inclined direction can be image 3 to the left of the , or image 3 On the right side of the figure, the inclination angles of several pressure blocks 4.2 increase sequentially; the inclination angle of the pressure block 4.2 closest to the driving part 1 is 0 degree. When all the pressure blocks 4.2 are pushed out to the outermost side, the pressing groove convex teeth 4.1 on the two adjacent pressure blocks 4.2 partially overlap; in the axial direction of the push shaft 2, th...

Embodiment 3

[0042] Such as figure 2 As shown, a cylinder shell air release groove processing device includes a push drive part 1, a push shaft 2, a fixed part 3 and several groove parts 4, the push shaft 2 and the fixed part 3 are slidably connected along the axial direction, and the push drive part 1 drives the fixed part 3 to slide, and several grooved parts 4 are uniformly arranged along the axis of the push shaft 2, and the grooved parts 4 are slidably connected with the fixed part 3. , the outer wall of the pressure groove part 4 is provided with several pressure groove convex teeth 4.1, and several pressure groove convex teeth 4.1 are uniformly arranged along the axis of the push shaft 2, and the inner side wall of the pressure groove part 4 is in contact with the push shaft 2, The side walls of the push shaft 2 and the groove member 4 are provided with a first slope 2.3, and the inner wall of the groove member 4 is provided with a second slope 4.4 adapted to the first slope 2.3; ...

Abstract

The invention discloses an air cylinder shell for an automobile gear shifting mechanism and an air leakage groove machining device. The air cylinder shell comprises a shell body, one end of the shell body is a sealing end, the other end of the shell body is an open end, a plurality of air leakage grooves are formed in the inner side wall of the shell body, the air leakage grooves are formed in the circumferential direction of the axis of the shell body, and the air leakage grooves are formed in the side close to the sealing end. The invention further discloses the air cylinder shell air leakage groove machining device. According to the air cylinder shell for the automobile gear shifting mechanism and the air leakage groove machining device, the two ends of a piston can be kept in communication when an air cylinder is located at the extreme position, the situation that the air cylinder and other parts connected with the air cylinder are damaged due to excessive pressure is avoided, rapid machining of the air leakage grooves is achieved, and the machining device is simple in structure, convenient to operate, low in machining cost and high in machining efficiency.

Description

technical field [0001] The invention relates to the technical field of cylinder housings in gear shifting mechanisms, in particular to a cylinder housing and a vent groove processing device for a gear shifting mechanism of an automobile. Background technique [0002] Cylinder is a kind of driving part commonly used in the shifting mechanism of automobiles. In order to prevent the cylinder in the shifting mechanism from damaging the cylinder and other parts connected with the cylinder at the extreme position, it is necessary to set up some pressure relief structures. For the cylinder housing of the shifting mechanism of the automobile, the pressure is relieved by setting an air release groove on the inner wall of the cylinder housing. Due to the small size and large number of vent grooves, if CNC machine tools are used for processing, it will lead to high processing costs and low processing efficiency. Therefore, the inventor also designed a processing device for air release...
