Problems solved by technology

Since the horizontal hole must be drilled from the inside of the diesel engine frame mounting hole to the outside, currently only a pistol drill can be used to drill the horizontal hole, and the drilling direction is difficult to control, which may easily cause the horizontal hole and the vertical hole to penetrate in a biased manner, affecting the circulation of cooling water. Thus affecting the cooling effect of the rack

Embodiment Construction

[0015] The present invention will be further described below in conjunction with drawings and embodiments.

[0016] Such as Figure 1 ~ Figure 2 As shown, the present invention includes a positioning plate 1, a drilling mechanism 2 arranged under the positioning plate 1, and a feed mechanism 3 on the positioning plate. The positioning plate 1 is embedded in the cylinder liner mounting hole of the diesel engine through the positioning disc 11 on the lower side, and the positioning Disk 11 serves as the plane and radial installation positioning datum of the present invention. The elastic positioning pin 4 is vertically arranged on one end of the positioning plate 1, and the positioning plate 1 is positioned on the installation hole of the cylinder liner of the diesel engine through the elastic positioning pin 4. The elastic positioning pin 4 can be used as a positioning reference for the drilling angle of the horizontal hole of the cylinder liner installation hole of the diesel...

Abstract

The invention discloses a horizontal hole drill for cooling water passages of diesel engine cylinder liner-mounting holes, which comprises a positioning plate, a drilling mechanism and a feed mechanism, and the positioning plate is embedded into a diesel engine cylinder liner-mounting hole through a positioning disk on the lower side of the positioning plate. The drilling mechanism comprises a motor, a motor base, a pair of engaged small cone gears, a big cone gear and a horizontal spindle, and the feed mechanism comprises an operating handwheel, an operating handwheel shaft, an engaged gear-rack pair, a gear base and a pair of linear rolling guide rails. By adopting the pair of engaged spiral bevel gears to change power direction, the horizontal hole drill can accurately drill horizontal holes in the radial narrow space of the diesel engine cylinder liner-mounting hole and improve the cooling effect of a housing. By adopting the linear rolling guide rails as the horizontal feed base of the feed mechanism, the horizontal hole drill can guarantee the linearity of a fed drill bit, and because the feed mechanism with the gear-rack pair can be smoothly operated, the feed precision is increased.

Description

technical field [0001] The invention relates to a drilling device for a diesel engine frame, in particular to a device for drilling a horizontal hole of a cooling water channel from the installation hole of the diesel engine frame to the outside, and belongs to the technical field of special equipment for metal cutting. Background technique [0002] The frame is one of the key components of the diesel engine, and it is the direct or indirect installation basis of all parts of the diesel engine. Its processing quality directly affects the overall performance and service life of the diesel engine. During the working process of the diesel engine, the frame and cylinder liner are subjected to high temperature and high pressure for a long time, and the working conditions are harsh. The frame and cylinder liner must be cooled in a timely and reliable manner to ensure their long-term and reliable operation. The cylinder liner installation holes of the frames of various models are e...
