Upper blanking mechanical clamping device for knife sharpening equipment

Abstract

The invention discloses an upper blanking mechanical clamping device for knife sharpening equipment. The upper blanking mechanical clamping device comprises an upper fixing plate and a lower fixing plate, wherein a piston is installed between the upper fixing plate and the lower fixing plate, an air cylinder body is arranged on the outer side of the piston in a sleeving mode, an upper air inlet and outlet connector is arranged at the top of the upper fixing plate, an upper air storage cavity is formed by the upper portion of the air cylinder body and the piston, a lower air inlet and outlet connector is arranged at the bottom of the lower fixing plate, a lower air storage cavity is formed by the lower portion of the air cylinder body and the piston, a movable fork is connected to the outer side of the air cylinder body in a sliding mode, and a rear fixing plate is connected to the rear side of the upper fixing plate and the rear side of the lower fixing plate. The rear fixing plate is rotatably connected with a rotating shaft, the rear side of the movable fork is connected with the rotating shaft, the right side of the rotating shaft is connected with a movable clamp, and a fixed clamp corresponding to the movable clamp is installed on the right side of the rear fixing plate. The upper blanking mechanical clamping device is stable in operation, long in service life and low in maintenance cost, and the utilization rate of knife grinding equipment is increased.

Description

technical field [0001] The invention relates to the technical field of knife sharpening equipment, in particular to a clamping device for loading and unloading machinery used for knife sharpening equipment. Background technique [0002] The existing loading and unloading mechanical clamps realize automatic loading and unloading clamping, mainly including a standard pneumatic finger cylinder with an inner diameter of 16mm and a long gripper arm, so that the pneumatic finger cylinder can drive the two long gripper arms to close to the middle at the same time to clamp the cylindrical workpiece , but the traditional upper and lower clamps have low reliability and short service life in specific use. Whether it is using domestic or imported finger cylinders, it is difficult to use them for a long time in the harsh atomized chip oil environment. After one month of use, the jaws need to be replaced due to the loosening of the jaws, resulting in inaccurate loading and unloading, whic...

[0002] The existing loading and unloading mechanical clamps realize automatic loading and unloading clamping, mainly including a standard pneumatic finger cylinder with an inner diameter of 16mm and a long gripper arm, so that the pneumatic finger cylinder can drive the two long gripper arms to close to the middle at the same time to clamp the cylindrical workpiece , but the traditional upper and lower clamps have low reliability and short service life in specific use. Whether it is using domestic or imported finger cylinders, it is difficult to use them for a long time in the harsh atomized chip oil environment. After one month of use, the jaws need to be replaced due to loose loading and unloading, which leads to low utilization rate of the sharpening equipment and high maintenance costs.
