Description

Drilling device and multi-station drilling device thereof

Technical field

本发明涉及钻孔装置及其多工位钻孔设备，特别涉及精密的多工位钻孔装置。The present invention relates to a drilling apparatus and a multi-station drilling apparatus thereof, and more particularly to a precision multi-station drilling apparatus.

Background technique

现有的钻孔方式多是采用手动钻或钻孔机械利用钻头在工件上进行单个钻孔。也有采用多孔钻的方式，利用多个钻夹头夹持多个钻头同时对多个孔位进行钻孔。由于每一钻头都对应有一钻夹头，在采用多孔钻时，所能加工的两个相邻孔的孔间距是不能低于两个钻夹头的半径之和；对于一些微小孔间距，亦或两个相邻孔的孔间距小于两个钻夹头的半径之和时，无法采用现有的多孔钻进行同时钻孔的加工方式。发明人之前发明了一种钻头，如专利申请号201710415245.4，该种钻头设有多边形棱柱体的滑动杆部；采用同步带轮带动滑动杆部的传动方式，利用同步带轮带动钻头转动，钻头的滑动杆部同时相对同步带轮向下移动实现钻孔的方式，从而不需要使用钻夹头，实现可以在任意孔间距的多个孔位的同时加工，特别是适用小孔间距的多个孔位同时进行钻孔，具有大幅提高生产效率的优点。但由于该种钻头为专用的的钻头，其制造的成本高，同时结构上与现有的不带有滑动杆部的钻头结构上差异巨大，专用钻头与普通钻头两者之间难以进行结合或互换。Most of the existing drilling methods use manual drilling or drilling machines to drill a single hole on the workpiece. There is also a method of using a multi-hole drill to hold multiple drill bits while drilling multiple holes. Since each drill bit has a drill chuck, the hole spacing of two adjacent holes that can be machined is not lower than the sum of the radii of the two drill chucks; for some micro hole spacings, Or when the hole spacing between two adjacent holes is less than the sum of the radii of the two drill chucks, it is not possible to use the existing porous drill for simultaneous drilling. The inventor previously invented a drill bit, such as patent application No. 201710415245.4, which is provided with a sliding pole portion of a polygonal prism; a transmission method of driving the sliding rod portion by a synchronous pulley, and the rotation of the drill bit is driven by the synchronous pulley, the drill bit The sliding rod portion simultaneously moves downward with respect to the synchronous pulley to realize drilling, thereby eliminating the need to use a drill chuck, and simultaneously processing a plurality of holes at any hole pitch, in particular, a plurality of holes for a small hole pitch. The simultaneous drilling of holes has the advantage of greatly increasing production efficiency. However, since the drill bit is a dedicated drill bit, the manufacturing cost thereof is high, and the structure is different from the existing drill bit structure without the sliding rod portion, and it is difficult to combine the special drill bit with the ordinary drill bit or exchange.

At the same time, when the wall of the installation hole is damaged, it is not necessary to remove the entire upper mold for maintenance and repair, only need to take out the transmission sleeve for maintenance, repair or replacement, which simplifies the maintenance work, reduces the maintenance time and reduces the maintenance of the device. cost. In the multi-station drilling equipment, the accuracy and precision of the hole spacing between the holes are achieved. An oil groove is provided in the porous drilling device to achieve lubrication during metal processing, to ensure processing effect and to extend the life of the processing tool, and to improve processing performance. The multi-station drilling device of the invention adopts a multi-station precise positioning drilling method, and combines the holes drilled by the front and rear working steps to avoid the need to set up a micro-pitch drilling device on a multi-station drilling device. The drilling method is combined with the drilling method of the drilling device of the invention to accurately position the workpiece between the front and the rear steps, thereby realizing the workpiece processing of the micro-pitch holes.
