Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinder processing, in particular to a hydraulic cylinder barrel punching device. Background Art

[0002] The hydraulic cylinder is a commonly used hydraulic component, which consists of a cylinder barrel, a piston and a seal. There are usually some small holes in the cylinder barrel of the hydraulic cylinder. These small holes have different functions. The most common small holes are the exhaust holes or oil drain holes on the cylinder wall. The exhaust holes are mainly used for ventilation and exhaust during the installation and use of the hydraulic cylinder to prevent the gas from mixing with the hydraulic oil and affecting the normal operation of the hydraulic system. The oil drain hole is used to discharge the hydraulic oil in the hydraulic cylinder, such as when the hydraulic cylinder is disassembled or the hydraulic seal is replaced. In addition to the exhaust holes and oil drain holes, there are some other small holes in the hydraulic cylinder, such as the oil adjustment hole, sensor hole, etc., and their functions are also different. The location and size design of these small holes need to be considered according to the use, installation and maintenance of the hydraulic cylinder to ensure the normal operation of the hydraulic system.

[0003] At present, machining centers and other equipment are usually used to drill holes in cylinder barrels. When drilling, the cylinder barrel is clamped with a bench vise and then programmed for positioning. This drilling method has the following defects: (1) The cylinder barrel is long and does not meet the processing conditions of conventional machining centers. It is necessary to customize or purchase a large-scale machining center, resulting in high production costs; (2) The cylinder barrel is difficult to clamp and the clamping time is long; (3) The professional requirements for operators are high; (4) The machining center occupies a large area and has high energy consumption.

The vertical automatic drilling machine in the utility model is the prior art; the cylinder barrel support assembly is used to place and support the cylinder barrel; the positioning baffle is used to position the cylinder barrel in the horizontal direction, that is, the cylinder barrel is pressed against the positioning baffle to achieve the positioning of the cylinder barrel, so as to ensure the accuracy of the punching, and the positioning is simple; the clamping mechanism is used to press the cylinder barrel when punching to prevent the cylinder barrel from moving or rolling; when the utility model is used, the cylinder barrel is placed on the support assembly, and the cylinder barrel is pushed toward the positioning baffle until the cylinder barrel and the positioning baffle are pressed against each other, and after the clamping mechanism presses the cylinder barrel, the vertical automatic drilling machine can drill the cylinder barrel, and the operation is very simple.

[0006] Preferably, the cylinder support assembly comprises at least two spaced support plates, each of which is provided with a V-shaped support opening. The support plate has a simple structure, and the V-shaped opening can be applied to cylinders of different diameters, thereby improving the versatility of the utility model.

[0007] Preferably, the angle of the V-shaped support opening is 90°~120°.

[0008] Preferably, a slider is provided at the bottom of the support plate, a slide groove matching the slider is provided on the table top of the machine, and the support plate and the table top of the machine are fastened together by connecting bolts. The support plate can move along the slide groove to adjust the distance between the support plates to adapt to cylinders of different lengths, thereby improving the versatility of the utility model.

[0009] Preferably, the support plate is provided with a connecting hole, and the connecting bolt passes through the connecting hole and is threadedly connected to the table top of the machine.

[0010] Preferably, the clamping mechanism comprises a cylinder, a clamping block is fixed to the end of the piston rod of the cylinder, and the cylinder is fixedly connected to the vertical automatic drilling machine.
