Abstract
The utility model relates to a drilling machine, particularly to a belt type heavy-duty bench drilling machine which comprises a base plate, a stand column, a workbench, a spindle box, a holder and an anti-drag structure. The stand column is fixedly arranged on the base plate; the workbench is arranged on the stand column; the spindle box is sleeved outside the upper portion of the stand column; the spindle box is fixedly arranged on the holder which is sleeved outside the stand column; the anti-drag structure which is fixedly arranged on the holder is arranged between the holder and the stand column. According to a steel ball circulating structure that the spindle box is fixedly arranged on the holder which is sleeved outside the stand column and the anti-drag structure which is formed by a steel ball and a housing of the steel ball is arranged between the holder and the stand column, sliding friction force is changed into rolling friction force, the resistance is greatly reduced, and lifting operation is portable.
Description
Technical field
The utility model relates to a kind of drilling machine, the heavy bench drill of especially a kind of belt-type.
Background technology
Bench drill is called for short bench drill, is that a kind of volume is small and exquisite, and is easy and simple to handle, usually is installed in the small-sized hole processor bed that uses on the dedicated, and the bench drill bore diameter is generally below 13 millimeters, and maximum is no more than 16 millimeters.Its main shaft speed change is generally realized by changing the position of V-belt on the tower belt wheel, the moving operation of axis feeding armrest.Bench drill can be placed on the operation post, the vertically arranged small drilling machine of main shaft.Vertical drilling spindle case and workbench are placed on the column, the vertically arranged drilling machine of main shaft; Radial drilling machine can be around column revolving, lifting, and main spindle box can move horizontally at rocking arm usually; The milling and drilling machine workbench can be in length and breadth to movement, and auger spindle is arranged vertically, and can carry out the drilling machine of milling; The hole depth drilling machine uses special deep hole drill, workpiece rotating, the drilling machine of deep hole drilling; Flush end face centre-drilling lathe cutting axis class end face and the centre-drilling lathe of processing with centre drill.
Heavy bench drill because its deadweight is heavier, because main spindle box in descending operation, is to utilize guide rail structure, is carried out, but because deadweight is heavier, so when the main spindle box lifting, comparison of resistance is large, descending operation is relatively more difficult.
Summary of the invention
The purpose of this utility model is, provides the light belt-type of a kind of descending operation heavy bench drill.
The technical scheme that its technical problem that solves the utility model adopts is: the heavy bench drill of a kind of belt-type, comprise base plate, column, workbench, main spindle box, column is fixedly installed on the base plate, workbench is arranged on the column, and main spindle box is set on the column of workbench top, also comprises support, drag reduction structure, main spindle box is fixed on the support, support casing is located on the column, and the drag reduction structure is fixed on the support, between support and column.
Of the present utility modelly further be set to: the drag reduction structure comprises steel ball, steel ball shell, steel ball shell hollow, and the face of corresponding column is provided with the drag reduction groove, and steel ball is arranged in the steel ball shell, and sphere exposes the drag reduction groove, with the column Surface Contact.
Said structure is fixed on main spindle box on the support, support casing is located on the column, between support and column, be provided with one, the drag reduction structure that is consisted of by steel ball and steel ball, utilize this steel ball loop structure, force of sliding friction is become force of rolling friction, greatly reduce resistance, it is light that descending operation just becomes.
Description of drawings
Fig. 1 is the structural representation of present embodiment;
The specific embodiment
With reference to the figure 1 heavy bench drill of a kind of belt-type as can be known, the heavy bench drill of a kind of belt-type, comprise base plate 1, column 2, workbench 3, main spindle box 4, column 2 is fixedly installed on the base plate 1, workbench 3 is arranged on the column 2, main spindle box 4 is set on the column 2 of workbench 3 tops, and main spindle box 4 is fixed on the support 5, and support 5 is set on the column 2, steel ball shell 6 hollows, and be fixedly installed on the support 5, corresponding with column 2, the face of corresponding column 2 is provided with drag reduction groove 61, steel ball 7 is arranged in the steel ball shell 6, sphere exposes drag reduction groove 61, with column 2 Surface Contacts, steel ball 7, steel ball shell 6 consists of the drag reduction structure.
