Description

本实用新型涉及的是一种单根工作主轴的固定式钻孔装置,特别是高速电动钻孔装置,属于钻床类。 The present invention relates to an apparatus fixed drilling work spindle of a single, high-speed electric drilling device in particular, belongs to the class drilling.

目前高速台式钻床可分为两种类型,一种是气动台钻,这种台钻用压缩空气作为动力源,采用风膜静压轴承,转速较高,一般在30000r/min以上,且噪音较小,然而这种台钻的制造精度要求较高,结构复杂,制造比较困难,故售价高,就国内厂家生产的产品来讲,单台售价高达1.6万元,而同类进口产品的价格更高,达8000美元。 Drilling speed desktop currently divided into two types, one is the pneumatic bench, this bench using compressed air as a power source, a hydrostatic bearing using air film, the higher speed, generally 30000r / min or more, and more noise small, however, this higher manufacturing precision bench drill requirements, complex, difficult to manufacture, so the price is high, it is the domestic manufacturers of products in terms of a single price up to 16,000 yuan, while the price of similar imported products higher, up to $ 8,000. 另一种就是电动高速台钻,这种台钻的构成是有一底座,底座上固定有竖直的立柱,立柱上固定有主轴箱和电机,主轴箱内安置有可上下移动的带有可转动主轴的套筒,电机则是通过皮带传动装置带动主轴高速转动的。 Another is the electric high-speed bench, this bench is composed of a base fixed to the vertical uprights on the base, and a motor fixed on the column headstock, a movable headstock disposed vertically rotatable with a spindle sleeve, a spindle motor is driven by the high-speed rotation of the belt drive. 工作时,开启电机,电机皮带轮便通过皮带带动主轴皮带轮,再通过与主轴皮带轮一体的花键套同主轴上的花键相配合将动力传递给主轴,使主轴高速转动,此时按动主轴箱一侧上的进刀手柄,通过安置在主轴箱内的齿轮轴与套筒上的齿条啮合,带动主轴下移,实现进刀过程。 In operation, the motor is turned on, the spindle motor pulley will be driven by a belt pulley, and then matched by transmitting power to the main shaft splines on the spindle pulley integrated with the spline housing with the spindle, the spindle rotates at high speed, then press the headstock on the infeed side of the handle, through the rack gear disposed on the gear shaft and the sleeve of the headstock, the spindle drive down to achieve feed process. 这种结构的电动高速台钻,在工作进刀时,电机(及电机皮带轮)和主轴皮带轮(包括与之一体的花键套)是不随主轴一起下移的,主轴所得到的连续不断的动力是通过花键套与花键的啮合传递来得到的,由于主轴的转速极高,花键套与花键的啮合必然带来撞击声音,导致噪声增大;同时还因台钻工作时,主轴要上下运动,即花键要在花键套内移动,这样就要求花键,套筒内外圆,主轴箱上的套筒孔和轴承孔等相对花键套要有很高的同轴度,否则当套筒连着主轴上下移动时,就会因上述因素反映出运动精度低,从而导致花键同花键套的配合精度变低,最终将导致噪声超标,即超过国家规定85分贝的要求。 Such structure-speed electric bench drill, in operation feed motor (motor and pulley) and spindle pulley (including spline sleeve integral therewith) are not down together with the main shaft, the main shaft of the continuous power obtained is obtained by transmitting engagement with the spline sleeve splines due to a high spindle speed, the engaging sleeve spline and the spline will inevitably bring the slapping noise, resulting in an increase in noise; due also when the work bench, spindle be moved up and down, i.e., splined sleeve to move the spline, the spline so required, the sleeve inner and outer round hole in the sleeve bearing hole headstock and the like have a high degree of key sleeve coaxially relative flowers, otherwise, when the sleeve is attached to the main shaft moves up and down, due to the above factors will be reflected in the motion accuracy is low, resulting in spline fitting with the spline sleeve accuracy becomes low, it will eventually lead to excessive noise, i.e. over 85dB national requirements . 很显然,要减少噪音,就必须大大提高零件的加工精度和装配精度,而实际上这几乎已到了一般机加工的极限,装配的难度也超过了一般所能承受的程度。 Obviously, to reduce noise, it is necessary to greatly improve the precision and assembly precision parts, but in fact it has almost reached its limit general machining, assembly difficulty also exceeded the level of general can bear.

本实用新型的目的是为了克服上述存在的不足,而提供一种对现有电动高速台式钻床进行改进而成的,能显著减少工作噪声的高速台式钻床。 The object of the present invention is to overcome the above deficiencies exist, and provide an existing electric drill for high-speed desktop improvements made, can significantly reduce the operation noise of high-speed desktop drilling.

本实用新型的目的是通过如下技术方案来完成的,即将电机固定安置在与主轴套筒相固连的电机连板上,取消了花键与花键套,在进刀时,电机通过电机连板与套筒一起上下移动,也就是说电机(及电机皮带轮)与主轴(及主轴皮带轮)一起上下移动。 Object of the present invention is achieved by the following technical solution to complete, i.e. the motor is fixed and arranged in a spindle sleeve is connected fixedly connected to the motor plate canceled spline spline sleeve, during preprocessing, the motor is connected by a motor move up and down together with the sleeve board, that is to say the motor (and the motor pulley) and the spindle (and spindle pulley) moves up and down together. 从根本上消除了高速台钻最大的噪声源。 Eliminating the high-speed bench drill biggest noise source fundamentally.

为减少电机连板单臂悬挂力的平衡问题,本实用新型采用竖直的圆管立柱,管内放置有配重块,该配重块通过滑轮用绳带与电机连板相连。 In order to reduce the motor attachment plate suspended cantilever force balance, the present invention uses the column pipe vertical, the counterweight is placed an inner tube, which is connected with the counterweight rope pulley via the motor attachment plate.
