Special fixture for monkey spanner milling groove

Abstract

The invention discloses a special fixture for a monkey spanner milling groove. The fixture comprises a bottom plate, a left support is fixedly arranged at the left end of the bottom plate, a right support is fixedly arranged at the right end of the bottom plate, a guide frame is fixedly arranged on the bottom plate between the left support and the right support; a fixed groove which is matched with the front end of a fixed wrench of the monkey spanner is arranged at the upper end of the guide frame, a hydraulic cylinder is fixedly arranged at the upper end of the left support, the end of a piston rod of the hydraulic cylinder is matched with one end of a mounting hole on the fixed wrench of the monkey spanner, a positioning thimble is arranged at the upper end of the right support, the end of the positioning thimble is matched with the other end of the mounting hole on the fixed wrench of the monkey spanner. The invention has the following advantages: clamping and fixing are convenient, machining accuracy is improved and monkey spanner milling groove operation can be finished by only one clamping, so that the trouble of repeated tool setting is saved, processing efficiency is enhanced and the fixture can be applied to clamping and fixing of various types of monkey spanners.

Description

technical field [0001] The invention relates to a clamping device, in particular to a special clamp for slot milling of an adjustable wrench. Background technique [0002] Currently on the market, there are generally four types of adjustable wrenches commonly used, No. 6 adjustable wrench, No. 8 adjustable wrench, No. 10 adjustable wrench and No. 12 adjustable wrench. During the processing of the adjustable wrench, the adjustable wrench needs to be milled. When the adjustable wrench is milled, the adjustable wrench to be processed needs to be fixed on the workbench. The clamping method currently used is mostly manual clamping, that is, the workpiece is fixed on the workbench with tools such as pressure plates and bolts, which is very inconvenient to operate. Multiple clamping, in the process of multiple clamping, because the position of the workpiece is different each time, the tool must be re-set after each clamping, the operation is cumbersome, the processing efficiency i...

The clamping method currently used is mostly manual clamping, that is, the workpiece is fixed on the workbench with tools such as pressure plates and bolts, which is very inconvenient to operate. Multiple clamping, in the process of multiple clamping, because the position of the workpiece is different each time, the tool must be re-set after each clamping, the operation is cumbersome, the processing efficiency is low, and the machining accuracy of the parts is artificially affected. The influence of factors is large, and the precision stability is poor
