Abstract

The utility model discloses an automatic bench drill which comprises a main shaft box and a main shaft which is arranged below the main shaft box and drives a drill bit to rotate. A hydraulic cylinder is vertically connected outside the main shaft box, and the piston rod of the hydraulic cylinder is connected with the main shaft through an intermediate plate. A guide rod is arranged parallel to the hydraulic cylinder, and the lower end of the guide rod is fixedly arranged on the intermediate plate. An upper approach switch and a lower approach switch are fixedly arranged on the guide rod. An upper locating block and a lower locating block are arranged on the main shaft box. The upper approach switch and the low approach switch are in controlling connection with the hydraulic cylinder through solenoid valves. The automatic bench drill can automatically and vertically drill fraising, reduces labor intensity, and improves production efficiency and finished product precision.

Description

A kind of automatic bench drill
Technical field
The utility model relates to a kind of bench drill, especially a kind of drilling machine of the hole that can drill and ream up and down automatically.
Background technology
Bench drill is that a kind of volume is small and exquisite, and is easy and simple to handle, is installed in the small-sized hole processor bed that uses on the dedicated usually.At present, the equal armrest of the feeding of bench drill main shaft moves operating grip, rocking arm etc., and repeated labor intensity is big, production efficiency is low; And because workman's operative skill difference, precision and the yield rate of processing also differ widely.
Summary of the invention
At above-mentioned weak point of the prior art, the utility model provides a kind of automatic bench drill, and the hole that can drill and ream up and down automatically reduces labour intensity, enhances productivity and finished product accuracy.
The technical solution of the utility model is a kind of automatic bench drill, comprises that main spindle box reaches the main shaft of the drive drill bit rotation that vertically is arranged on the main spindle box below, and described main spindle box vertically is connected with hydraulic cylinder outward, and the piston rod of described hydraulic cylinder is connected with main shaft by intermediate plate; Be parallel to described hydraulic cylinder and be provided with guide rod, lower end and the intermediate plate of described guide rod are fixed; On fixedly having on the described guide rod near switch, down near switch, described main spindle box is provided with locating piece, following locating piece, described near switch, control with hydraulic cylinder by magnetic valve near switch and be connected down.
Further, described hydraulic cylinder is fixed on the main spindle box by upper and lower end plate; Described guide rod pass bottom plate and with its matched in clearance.Guide rod is when moving up and down, and bottom plate can open the effect of guiding, and it is crooked to avoid guide rod to take place.
Further, described intermediate plate is perpendicular to the piston rod of main shaft and hydraulic cylinder.Be beneficial to stable drive.
Further, on described near switch and down near the distance between the switch less than the distance between last locating piece and the following locating piece.Guarantee when up, near inductive switching to last locating piece, and under can not sense down locating piece near switch; In descending, under having only near locating piece under the inductive switching.
Further, on described near switch, be eddy current type near switch near switch down.Eddy current type is good near switching response frequency height, anti-environmental disturbances performance, applied range, price are lower.The beneficial effects of the utility model are: hydraulic cylinder drives main shaft, drill bit and the upper and lower movement of guide rod, when following on the guide rod arrives the correspondence position of locating piece down near switch, just can control the magnetic valve commutation near switch down, thereby hydraulic cylinder is up automatically; When up, on rise to the position corresponding with last locating piece near switch, on just can control magnetic valve near switch and make hydraulic cylinder descending automatically; Finally realize drilling and reaming up and down automatically the hole, reduce labour intensity, enhance productivity and finished product accuracy.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model structural representation.
The specific embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of automatic bench drill comprises that main spindle box 1 reaches the main shaft of drive drill bit 5 rotations that vertically are arranged on main spindle box 1 below as shown in Figure 1, the described main spindle box 1 outer hydraulic cylinder 2 that vertically is connected with, and the piston rod 3 of described hydraulic cylinder 2 is connected with main shaft by intermediate plate 4; Be parallel to described hydraulic cylinder 2 and be provided with guide rod, the lower end of described guide rod and intermediate plate 4 are fixing; On fixedly having on the described guide rod near switch 6, down near switch 7, described main spindle box 1 is provided with locating piece 8, following locating piece 9, described near switch 6, down near switch 7 by magnetic valve and hydraulic cylinder 2 control connections.Described hydraulic cylinder 2 is fixed on the main spindle box 1 by upper and lower end plate; Described guide rod pass bottom plate and with its matched in clearance.Institute's intermediate plate 4 is perpendicular to the piston rod 3 of main shaft and hydraulic cylinder 2.On described near switch 6, down near the distance between the switch 7 less than last locating piece 8, the following distance between the locating piece 9.On described near switch 6, be eddy current type near switch near switch 7 down.
On described near switch 6 and down near the distance between the switch 7 and can be greater than the distance between last locating piece and the following locating piece 9; Descend locating piece 9 need be arranged on locating piece 8 tops so, also will be arranged near switch 6 tops near switch 7 under corresponding; But arrange like this, the minimum point that drill bit 5 can arrive raises, peak reduces, to such an extent as to whole stroke range shortens.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
