Abstract
The invention discloses a granite sliding block-based micro punching drive device, which relates to a micro punching drive device. The device solves the problems of the prior double liner motor-based micro punching drive device, such as large friction and thermal deformation and low positioning and operation precision. A sliding block (6) of the device is made of granite and is provided with at least four mounting holes (11), the inside of each mounting hole (11) is embedded with a connecting sleeve (10), and the secondary (8) of each liner motor (2) is fixedly connected with sliding block (6) through the connecting sleeve (10). The device uses the liner motors to drive the sliding block directly, avoids error accumulation caused by a driving step, generates small friction and thermal deformation, greatly reduces the influences of heat generated during motion on the positioning precision, improves the positioning precision and easily achieves the high speed and precision required for micro punching. In addition, the device improves the stress condition of the sliding block and improves operation precision due to the additional connecting sleeves.
Description
Technical field
The present invention relates to a kind of micro-impact briquetting drive device, belong to the accurate mechanical equipment technical field.
Background technology
The part geometry size of micro-plasticity forming is very small, movement velocity, positioning accuracy and the shaping efficiency of former has been proposed very high request, and required equipment can realize the accurate control of displacement and plastic force.Traditional slider-crank mechanism and hydraulic-driven, air pressure drive and the former of Piezoelectric Driving because complex structure, shortcoming such as inertia is big and response frequency is low, all can't satisfy the needs of micro-plasticity forming high position precision and high movement velocity.Publication number is CN101206481A, open day be that the patent of invention that June 25 in 2008, day, were called " based on the little punching press drive system of the high-speed, high precision of dual linear motor " proposes a kind of little punching press drive system based on dual linear motor.This little punching press drive system is owing to the reciprocating motion of punching press, and the slide block place inevitably produces friction, and then causes thermal deformation, influenced the positioning accuracy of whole system, and the stressing conditions of slide block has influenced the running precision of whole system.
Summary of the invention
To the objective of the invention is that the existing friction that exists based on the little punching press drive system of dual linear motor is big, thermal deformation big and location and the low problem of running precision in order solving, and then a kind of micro-impact briquetting drive device based on granite slide block to be provided.
Technical scheme of the present invention is: a kind of micro-impact briquetting drive device based on granite slide block comprises two connecting plates, two linear electric motors, article four, line slideway, eight guide rail slide blocks and slide block, described two parallel being set up in parallel of connecting plate, slide block is arranged between two connecting plates, the bilateral symmetry that slide block and two connecting plates are adjacent is provided with linear electric motors, elementary and the adjacent connecting plate of each linear electric motors is affixed, symmetrically arranged line slideway before and after the top and bottom of the two sides that slide block and two connecting plates are adjacent are fixed with respectively, every line slideway is all along vertical setting of driving arrangement, two guide rail chutes of every line slideway and corresponding two guide rail slide blocks are slidingly matched, each guide rail slide block is all affixed with adjacent connecting plate, described slide block is made by grouan material, described micro-impact briquetting drive device also comprises at least four adapter sleeves, have at least four installing holes on the described slide block, each installing hole is embedded with an adapter sleeve, each linear electric motors secondary affixed by adapter sleeve and slide block.
The present invention has following beneficial effect: the present invention adopts linear electric motors directly to drive the slide block that grouan material is made, the deviation accumulation of having avoided transmission link to cause, the grouan material thermal coefficient of expansion is little, internal stress free, and density low (close) with metallic aluminium, the slide block that adopts grouan material to make, as the connector between two linear electric motors, also be the power output and the straight-line executive item of punching mechanism, its friction is little, thermal deformation greatly reduces the influence of motion heating to positioning accuracy for a short time, improved positioning accuracy, the slide block inertia that grouan material is made is low, is easier to the high-speed and high accuracy that realizes that little punching press is required.The present invention is converted into tension to adapter sleeve by the tension to slide block that has increased adapter sleeve the attraction between the primary and secondary of two linear electric motors caused in addition, and the pretightning force by adjustment screw, make it become compression to slide block, improve the stressing conditions of slide block, improved running precision.
