Problems solved by technology

[0003] In the boring process on the horizontal machining center, the fixation of the connecting rod workpiece is not good when placed in the fixed fixture assembly of the horizontal machining center, which can easily lead to poor machining accuracy, resulting in the need for multiple round-trip processing of the product, and different types of The connection position and angle of the small head of the connecting rod, the connecting rod part and the connecting rod part of the connecting rod workpiece are not the same, so that different types of connecting rod workpieces need to be installed and disassembled to replace different fixing fixture components. The performance is extremely poor, which seriously affects the production efficiency and the cost is extremely high

Abstract

The invention discloses an automobile connecting rod fixing clamping device. The device comprises a fixing base, a fixing clamping assembly, a clamping positioning assembly and a connecting rod workpiece, wherein the fixing clamping assembly and the clamping positioning assembly are fixedly arranged on the fixing base; and the connecting rod workpiece is arranged between the fixing clamping assembly and the clamping positioning assembly, one end of the connecting rod workpiece is connected in the fixing clamping assembly in a clamped mode and the connecting rod workpiece is axially fixed through a limiting clamping piece and a positioning clamping block of the fixing clamping assembly, and the other end of the connecting rod workpiece is connected in a clamping groove of the clamping positioning assembly in a clamped mode and the connecting rod big end of the connecting rod workpiece is radially positioned through the clamping positioning assembly. According to the device, the fixing effect is excellent, a product can be put into a general lathe for machining through the tool, the machining efficiency can be effectively improved, and the cost is greatly reduced; and a plurality ofmounting connecting hole grooves are uniformly distributed in the fixing base, and the fixing clamping assembly and the clamping positioning assembly are arranged in different mounting connecting holegrooves to be matched with the connecting rod workpieces of different models, so that the adaptability is excellent.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a fixing and clamping device for an auto connecting rod. Background technique [0002] The automobile connecting rod is an automobile part used to connect the piston and the crankshaft, transmit the force acting on the piston to the crankshaft, and convert the reciprocating motion of the piston into the rotational motion of the crankshaft. The existing connecting rod workpieces are usually processed with [0003] In the boring process on the horizontal machining center, the fixation of the connecting rod workpiece is not good when placed in the fixed fixture assembly of the horizontal machining center, which can easily lead to poor machining accuracy, resulting in the need for multiple round-trip processing of the product, and different types of The connection position and angle of the small head of the connecting rod, the connecting rod part and the connecting rod part of the...
