Gear shaping clamp for flange of transmission

Abstract

The invention belongs to the field of workpiece clamping devices, and particularly relates to a gear shaping clamp for a flange of a transmission. The gear shaping clamp comprises a machine frame, a linkage device and a clamping device; a positioning disc is fixedly arranged on the machine frame; a positioning spigot is formed in the positioning disc; the linkage device comprises a supporting rod,a cross rod, V-shaped shifting rods and push rods; a base plate is arranged at the upper end of the supporting rod and is connected in the positioning spigot in a sliding mode; a wedge groove is formed in the cross rod; clamping grooves are formed in the push rods; one ends of the V-shaped shifting rods abut against the cross rod, and the other ends of the V-shaped shifting rods are clamped in the clamping grooves in the push rods; a pressing plate is arranged at the upper ends of the push rods; the clamping device comprises piston cylinders and a clamping block; the piston cylinders are arranged at the bottom of the positioning spigot and communicates with the positioning spigot; wedge surfaces are arranged the piston rods, and the piston rods are fixedly connected to the push rods; andwedge rods are fixedly connected to the clamping block and abut against the piston rods. The gear shaping clamp has the advantages that the purpose of preventing displacement in the machining processof inner teeth of the flange can be achieved, and the gear shaping clamp is mainly used for fixing the flange in the machining process.

Description

technical field [0001] The invention belongs to the field of clamping devices for workpieces, and in particular relates to a gear shaping fixture for a transmission flange. Background technique [0002] During the process of inserting the internal teeth of the flange, due to the large insertion force, the flange will move, which will lead to the phenomenon of disordered teeth. In the process of clamping the flange, there will be a long time for alignment, which will affect the work efficiency. , The processing quality is low, its installation and disassembly is not convenient enough, and the flange plate has many shortcomings such as poor stability during the slotting process. [0003] For this reason, Chinese patent CN204430472U discloses a kind of flange plate gear positioning device, including: a positioning plate, the upper part of the positioning plate is provided with a positioning notch; the flange is placed inside the positioning notch; the middle part of the positio...

Problems solved by technology

[0004] However, the above-mentioned patent still has the following defects: only using the pressing block to clamp the lower part of the flange, it is difficult to provide a sufficient clamping force, the clamping effect is not good, and when the flange is clamped, manual labor is required. Tighten the bolts so that the pressure block is pressed against the flange, and the installation and disassembly are not convenient enough
