Description
Technical Field
The utility model relates to an engine drive parts processingequipment, concretely relates to engine crank throw terminal surface turn-milling processingequipment.
Background
The crank assembly of the engine is a component of the crank assembly of the engine, the crank assembly of the engine generally includes front axle, crankshaft flange, multiple crank throw, multiple roller bearings, the crank assembly can bear the force that the tie rod transmits, and change it into the torque and export through the crank assembly, and drive other accessories on the engine to work. The existing turning and milling processing mode of the end surface of the crank throw is single-piece clamping and single-piece turning and milling, and the working efficiency is low; and the rotary table is of a rotary type, a plurality of crank throws are arranged on the periphery of the rotary table, and the end surfaces of the crank throws (generally six crank throws) are sequentially turned and milled one by the rotary table and a cutter above the side of the crank throws through the rotation of the rotary table. And only one milling cutter is arranged on the cutter up and down, so that the machining precision is not high, the occupied space is large, the stability is not enough, and the working efficiency is not high.
SUMMERY OF THE UTILITY MODEL
In view of the not enough of background art, the utility model aims to solve the technical problem that a reciprocating type engine crank throw terminal surface turn-milling processingequipment that the straight line is reciprocal, occupation space is little, the operation is stable, processing is reliable is provided.
For this reason, the purpose of the utility model is realized by adopting the following scheme: the reciprocating engine crank end surface turning and milling device comprises a rack, a milling cutter and a crank clamping assembly, wherein the crank clamping assembly is arranged on a milling machine platform in a double-arrangement mode, the milling machine platform is arranged on a linear movement transmission assembly, and the linear movement transmission assembly is connected with a transmission power source; the milling cutter is in double rows and is positioned between the double-row crank clamping components, a plurality of blades are arranged on the double-row milling cutter, and the double-row milling cutter is connected with a milling cutter rotating power source.
By adopting the technical scheme, the crank throw is arranged on the crank throw clamping component, the transmission power source works to drive the linear movement transmission component to transmit, so that the milling machine platform and the crank throw on the milling machine platform are driven to linearly move, meanwhile, the milling cutter rotary power source works to rotate the double-row milling cutter, and the double-row milling cutter and the blades thereof are inserted between the crank throws arranged in double rows to perform turning and milling processing on the end surfaces of the crank throws. The multi-crank throw machine can process a plurality of double rows at one time, has small occupied space, is stable and reliable, has high working efficiency, improves the processing precision uniformity, and ensures and further improves the crank throw quality.

Detailed Description
As shown in fig. 1 and 2, the turning and milling device for the crank end face of the reciprocating engine of the present invention comprises a frame 1, a milling cutter 2, and a crank clamping assembly 4 (a plurality of) which is mounted on a milling machine platform 5 for double arrangement (front-back or left-right arrangement), wherein the milling machine platform 5 is mounted on a linear motion transmission assembly 12 (a linear lead screw, a moving block, etc.), and the linear motion transmission assembly 12 is connected with a transmission power source 6 (a power transmission motor mounted on the frame); the milling cutter 2 is in a double-row type (vertically arranged, determined by the vertically arranged end faces of the crank throws to be processed) and is positioned between the double-row type crank throw clamping components, a plurality of blades (comprising an upper milling cutter 7 and a lower milling cutter 8) are arranged on the double-row type milling cutter, and the double-row type milling cutter is connected with a milling cutter rotating power source 9 (which is a milling cutter rotating motor and is arranged on a rotating power source seat above the rack). The blade is composed of a plurality of upper milling blades 7 and lower milling blades 8, wherein the upper milling blades 7 and the lower milling blades 8 (both are a plurality of blades) are arranged in a vertically staggered manner at intervals (namely, one upper milling blade is positioned above the space between the two lower milling blades, and one lower milling blade is positioned below the space between the two upper milling blades).
As shown in fig. 1 and 3, the processed bell crank 3 is mounted on the bell crank clamping assembly 4 and arranged in front and back double rows (six pieces in front and back rows), the end surface of the bell crank is arranged up and down and divided into a bell crank upper end surface 10 and a bell crank lower end surface 11, the end surface of the bell crank is the part to be milled, the end surfaces of the double rows (two rows) of bell cranks are arranged face to face, and the double row milling cutter is positioned between the double rows of bell cranks arranged face to face. When in processing, the transmission power source 6 (which is a power transmission motor) works to drive the linear movement transmission assembly 12 to transmit (rotate), so as to drive the milling machine platform and the crank throw thereon to do left-right linear movement, meanwhile, the milling cutter rotation power source 9 (which is a milling cutter rotation motor) works to rotate the double-row milling cutter, and the double-row milling cutter and the upper and lower milling blades thereof are inserted between the double-row arranged crank throws to simultaneously turn and mill the upper and lower end faces of the crank throw. Twelve workpieces can be processed simultaneously by one-time linear reciprocating operation, the working efficiency is high, and the processing precision uniformity is improved.
