A CNC gear shaving machine

Abstract

A numerical control gear shaving machine comprises a machine base, a working table arranged above the machine base and a control panel hinged to the working table; a rack is arranged on one side of the working table, a tool mounting head is arranged on the rack, a tool is arranged on the tool mounting head, a first sliding way and a second sliding way are arranged on the left side and the right side of the working table correspondingly, a first positioning device matched with the first sliding way is mounted on the first sliding way, and a second positioning device matched with the second sliding way is mounted on the second sliding way; the first positioning device is connected with a first oil cylinder, and the second positioning device is connected with a second oil cylinder; and a sliding base is arranged between the first sliding way and the second sliding way. The numerical control gear shaving machine can automatically carry out tool setting, a worker does not need to carry out tool setting, in the tool setting process, the condition that due to collision of the tool and teeth of a gear, the teeth of the gear are damaged is avoided, positioning shafts of different shaft diameters can be more rapidly replaced, and it is ensured that the numerical control gear shaving machine can machine gears of different types.

Description

technical field [0001] The invention relates to a numerical control gear shaving machine. Background technique [0002] The CNC gear shaving machine can be used to process gears such as external meshing spur gears, helical cylindrical gears, drum-shaped teeth, and small taper gears, so that the gear teeth can be finished. The gears after finishing by the CNC gear shaving machine can be widely used in automobiles. , machine tools and other equipment, but the tool setting method of most CNC gear shaving machines is that the staff moves the tool down by controlling the cylinder to perform tool setting. Improper operation causes the tool to directly collide with the gear teeth instead of accurately entering the tooth groove between the gear teeth. When the tool collides with the gear teeth, the thrust formed by the cylinder is extremely strong, and the hardness of the tool is greater than that of the gear teeth. , so the tool is very easy to bruise the gear teeth, which affects...

[0002] The CNC gear shaving machine can be used to process gears such as external meshing spur gears, helical cylindrical gears, drum-shaped teeth, and small taper gears, so that the gear teeth can be finished. The gears after finishing by the CNC gear shaving machine can be widely used in automobiles. , machine tools and other equipment, but the tool setting method of most CNC gear shaving machines is that the staff moves the tool down by controlling the cylinder to perform tool setting. Improper operation causes the tool to directly collide with the gear teeth instead of accurately entering the tooth groove between the gear teeth. When the tool collides with the gear teeth, the thrust formed by the cylinder is extremely strong, and the hardness of the tool is greater than that of the gear teeth. , so the tool is very easy to damage the gear teeth, which affects the machining accuracy of the gear teeth, and cannot guarantee the quality of the processed gear

[0003] Generally, when the CNC gear shaving machine is processing the gear, the gear will be positioned by inserting the positioning shaft into the shaft hole on the gear. However, because the gear has many different types, and the shaft hole diameters of different types of gears are also different. , and the positioning shaft on the CNC gear shaving machine cannot be replaced due to structural problems, so the positioning shaft can only process the gear that matches it. If the shaft hole diameter of the gear to be processed does not match the shaft diameter of the positioning shaft, If it is necessary to process other types of gears, it needs to be moved to other matching CNC gear shaving machines for processing. This kind of processing method that can only process a single type of gear requires the user to purchase multiple sets with different The CNC gear shaving machine with the positioning axis of the coaxial diameter can process all different types of gears, which greatly increases the processing cost, and the existence of multiple CNC gear shaving machines increases the placement space, making the placement of CNC gear shaving machines difficult. The degree of trouble in the gear machine increases accordingly
