Technical Field

The utility model relates to a drilling machine field especially relates to special drilling machine of valve processing.

Background

The valve is a pipeline accessory used for opening and closing a pipeline, controlling the flow direction, adjusting and controlling parameters of a conveying medium, according to its function, it can be divided into shutoff valve, check valve and regulating valve, the valve is a control component in fluid conveying system, and possesses the functions of stopping, regulating and guiding, preventing counter-flow, stabilizing pressure, shunting or overflow and relieving pressure, valves used in fluid control systems, from the simplest shut-off valves to the various valves used in extremely complex autonomous systems, the variety and the specification of the valve are quite various, a drilling machine cannot be used for drilling holes in the production and processing process of the valve, because the key parts such as the valve core and the like can not be stressed, the requirements on the clamping direction and the angle for fixing the valve in the production and processing process are very strict, in the prior art, the clamping and fixing direction is mostly perpendicular to the surface of the workbench of the drilling machine, and the clamping and fixing in the parallel direction are difficult.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a simple structure is provided, can be at the special drilling machine of the fixed valve processing of workstation parallel direction centre gripping of drilling machine.

The utility model discloses a realize through following technical scheme:

the drilling machine special for valve processing comprises a base, an upright post, a rocker arm and a workbench, wherein one end of the upright post and the workbench are respectively fixed on the base, one end of the rocker arm is arranged at the top of the upright post, the other end of the rocker arm is provided with a vertical main shaft, the main shaft is positioned above the workbench, the side wall of the workbench is provided with a fixing hole and a plurality of bearings, the bearings are provided with gears, the outer side wall of each gear is provided with a handle, the handle can drive the gear to rotate around the bearing, a fixing pin which can be pulled out is arranged in the fixing hole, the fixing pin passes through one tooth groove of the gear and can prevent the gear from rotating, a vertical rack is arranged among a plurality of gears, the gear is meshed and connected with the rack in a bilateral symmetry mode, a movable clamp body is arranged at the top of the rack and located right above the workbench.

Furthermore, a concave arc-shaped sliding groove is formed in the top of the workbench.

Beneficial effects of the utility model

The utility model provides a special drilling machine of valve processing can provide through the gear rotation with workstation surface parallel direction's centre gripping fixed function, avoids key parts such as the case of valve atress deformation at the fixed in-process of centre gripping.

Furthermore, a concave arc-shaped sliding groove is formed in the top of the workbench, so that a drill bit is prevented from being touched and damaged during machining, and generated chips slide down along with the arc and are convenient to clean.

FIG. 1 is a schematic structural view of the present invention;

in the figure, 1, a base, 2, a column, 3, a rocker arm, 4, a main shaft, 5, a workbench, 6, a movable clamp body,

7. the handle, 8 rack, 9 fixed pin, 10 gear, 11 bearing, 12 fixed hole, 13 arc chute.

Detailed Description

As shown in figure 1, the bottom of the drilling machine special for valve processing provided by the utility model is a rectangular base 1, a welding upright post 2 is arranged at the side of the base 1, a workbench 5 welded on the base 1 is arranged at the side of the base 1, a concave groove-shaped arrangement, namely an arc chute 13 is arranged at the top of the workbench 5, the upper surface of the arc chute 13 is in an arc shape which bows upwards, a rocker arm 3 is arranged at the top of the upright post, a vertical main shaft 4 is arranged at the other end of the rocker arm 3, the product on the workbench 5 is drilled through the rotation of the main shaft 4, a fixed hole 12 is drilled on the side wall of the workbench 5, a plurality of bearings 11 are welded beside the arc chute 13, a gear 10 is arranged on the bearing 11, a handle 7 is welded at the central part of the outer side wall of the gear 10, the gear 10 can be driven to rotate around the bearing 11 by swinging the handle 7, a fixing pin 9 which can be pulled out is arranged in the fixed hole 12, the fixing pin 9 passes through a tooth socket of one gear 10 to prevent the rotation of the gear 10, a vertically arranged rack 8 is arranged in the middle of the plurality of gears 10, the bottom end of the rack 8 is widened towards the direction of the gears 10 on the two sides to prevent the gears 10 from falling off, the gears 10 are meshed and connected on the rack 8 in a bilateral symmetry mode, a movable caliper body 6 is welded at the top of the rack 8, and a downward vertical bulge is arranged at the free end of the movable caliper body 6 and is positioned right above the workbench 5.

When the valve needs to add man-hour at the drilling machine, place the valve on workstation 5, extract the fixed pin 9 that is located fixed orifices 12, wave handle 7, make gear 10 rotate and drive the downward vertical motion of meshing rack 8, when the vertical arch on the free end of activity pincers body 6 supports tight valve, stop to wave handle 7, pass fixed pin 9 the tooth's socket of gear 10 and insert the purpose that prevents gear 10 antiport in fixed orifices 12, the valve is firmly fixed on workstation 5 from this, the work of punching is done for the valve to the position that main shaft 4 aimed at arc spout 13, the piece falls into arc spout 13, and along with the upper bow slope landing of upper surface, convenient cleaning.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
