Description

Technical Field

[0001] The utility model relates to the technical field of anti-dropping mechanisms, in particular to an anti-dropping mechanism for cutting-in grinding materials. Background Art

[0002] The outer circle machining of the rolling element of the bearing is divided into through-type and plunge-in type. Usually, the plunge-in type has a relatively high precision and is used by most roller processing plants. The plunge-in type grinding tooling is divided into a loading area, a processing area and a unloading area. After the workpiece is processed, it leaves the equipment through the material channel in the unloading area.

[0003] Because the grinding wheel and the workpiece of the plunge grinding equipment need to be at a certain height before they can be processed, the material channel of the automated production line is usually lower than the height of the processing area, and the unloading channel is composed of two inner and outer inclined baffles. During the unloading process, the workpiece will be affected by the inclination angle and the falling speed will be accelerated, and the speed will be faster when it reaches the production line material channel. If it is not decelerated, since the unloading area of ​​the plunge grinding is usually not protected, and the grinding method of some machine tools is a fixed grinding wheel, the workpiece is ground close to the grinding wheel. This type of grinding method usually causes the loading and unloading areas to move forward and backward with the workpiece at the same time. Therefore, the tail end of the unloading area will be away from the production line material channel. The workpiece is very likely to rush out of the production line material channel during the unloading process, causing damage to the workpiece. In order to solve this technical problem, the utility model proposes a plunge grinding unloading anti-drop mechanism. Utility Model Content

[0024] A base 7 is installed on the outer side of one of the baffles 1, and the inner side of the base 7 is connected to the fixed end of the cylinder 8 for fixed-point rotation. The cylinder 8 is supported by the base 7 to provide supporting force for the cylinder 8. A support plate 9 is installed on the outer side of one of the baffles 1. The support plate 9 is located on one side of the unloading channel 6 and is connected to the L-shaped blocking rod 3 for fixed-point rotation. Two first slides 10 are provided on the inner side of the support plate 9, and the inner walls of the two first slides 10 are slidably connected with a sliding rod 11. The angle difference between the support plate 9 and the L-shaped blocking rod 3 is compensated by the first slide 10 and the second slide 12, so that the L-shaped blocking rod 3 can be adjusted by swinging the angle. Two second slides 12 are provided on the inner side of the L-shaped blocking rod 3, and the inner walls of the two second slides 12 are connected to the outer surfaces of the two sliding rods 11 for sliding movement.
