Embodiment 1

[0019] See attached figure 1 and 2 , the digital automatic control hydraulic multi-hole drilling machine of the present invention includes a bed 1, a clamping and positioning device located in the middle of the bed 1, and a clamping and positioning device located on both sides of the clamping and positioning device and slidingly limited on the slide rails of the bed 1. Power box 3, a drilling mechanism is arranged in the power box 3, and the drilling mechanisms on the two power boxes 3 are arranged oppositely. The bracket 5 extending in the chute 4 is connected to the hydraulic linear drive mechanism, and the power box 3 has a degree of freedom of movement along the slide rail by means of the hydraulic linear drive mechanism. The hydraulic linear drive mechanism is a hydraulic push rod 6, and the two ends of the hydraulic push rod 6 are connected with the support 5 and the bed 1 respectively. The bed 1 is a casting, and bed legs are provided at the lower part of the bed 1 . ...

Embodiment 2

[0024] The present invention can also reduce the preparation under certain requirements, save the synchronous device and the digital control device, and retain the hydraulic power device instead of the motor. At this time, the two power boxes 3 are respectively moved along the bed 1 slide rail moves. The power box 3 is provided with a drilling mechanism, and the drilling mechanism adopts gear transmission to make the drill bit rotate.

[0025] When parts need to be processed, the workpiece is placed on the positioning platform 8 and the compression cylinder 9 is pressed against the workpiece. The operation panel and the two power boxes 3 move to the workpiece and drill holes under the control of the hydraulic system to complete the drilling process on the workpiece. After the drilling was completed, the two power boxes 3 returned to their original positions respectively. Compress the oil cylinder 9 to unclamp, and the parts processed are moved out and the next workpiece to b...

Abstract

The invention discloses a digitized-automatic-control hydraulic multihole drilling machine. The digitized-automatic-control hydraulic multihole drilling machine comprises a machine body, a clamping and locating device and two power boxes, wherein the two power boxes are limited onto the machine body in a sliding manner; drilling mechanisms are arranged in the power boxes, a sliding groove is formed along the axial direction of the machine body, and brackets which extend into the sliding groove are arranged at the bottoms of the power boxes and are connected with hydraulic linear drive mechanisms; a synchronous feeding device is arranged below the hydraulic linear drive mechanisms and comprises a lead screw with positive and negative threads and hydraulic motors which are respectively arranged at the two ends of the lead screw, and the positive and negative threads of the lead screw are respectively connected with the brackets of the two power boxes so as to form lead screw-screw nut transmission pairs; a computer digitized automatic control device is further arranged on the machine body so as to carry out computer digitized automatic control on the drilling machine. According to the digitized-automatic-control hydraulic multihole drilling machine, hydraulic transmission is adopted, and synchronous operation and non-synchronous operation modes for the double drilling mechanisms are provided and can be switched freely, so that more requirements of machining can be met.

Description

technical field [0001] The invention belongs to the technical field of special machine tools, and in particular relates to a digital automatic control hydraulic multi-hole drilling machine. Background technique [0002] A drilling machine is a machine tool that uses a drill bit to process holes on a workpiece. Usually, the drill bit rotates as the main motion, and the drill bit moves axially as the feed motion. Its characteristic is that the workpiece is fixed during the machining process, the center of the tool is aligned with the center of the hole, and the tool is allowed to rotate. [0003] In the processing of some specific parts, such as piston rods, there are strict requirements on their coaxiality and wear resistance. In order to meet the above requirements, in the process of processing steel pipes into piston rods, it is required that the holes on the same cross section drilled by the drilling machine on the steel pipe must be located on the axis, which puts a high...
