Abstract

A slot grinder special for core penetrating rods can efficiently and accurately slot the long core penetrating rods. The slot grinder comprises a grinder seat, wherein the grinder seat is a rectangle body with an opening in the front face, and a manual pull rod is arranged on the back face of the grinder seat. Bearing seats are arranged at the two ends of the upper plane at the opening position of the grinder seat respectively, a shaft is mounted between the two bearing seats, and the shaft is hollow. The shaft is provided with a plurality of grinding wheels in a sleeved mode, and the adjacent grinding wheels are separated through spacer sleeves. One end of the shaft is connected with a motor through a coupling, and the motor is mounted on a motor base. Rails are arranged on the lower plane at the opening position of the grinder seat, and the reciprocating moving direction of the rails is parallel to the rotating direction of the grinding wheels. A workbench is arranged on the rails and can move synchronously with the rails, pressing bars are arranged on the workbench, the workbench is used for containing and clamping the core penetrating rods in a working process, and the pressing bars are used for tightly pressing the core penetrating rods. The slot grinder is simple in operation and high in working efficiency.

Description

Notch grinder

Technical field

The utility model relates to notch grinder, relates in particular to a kind of piecing assembly glass steel grating location punching bar (hereinafter to be referred as punching bar) Special grinding scouring machine.

Background technology

Punching bar is semicircle fiberglass rod, 5 millimeters of radiuses, and long 1 to 3 meter, Fig. 4 is punching bar partial enlarged drawing, on this punching bar, opens a sulculus every 38 millimeters of needs.In the time of glassing steel grating, this punching bar inserts in porose fiberglass load-bearing I-section profile hole, by interference fit, is assembled into sheet grid with another root slotless punching bar.Because the punching bar of 1 meter long will be opened 27 grooves, 3 meters long punching bars will reach 79 grooves, and each trough has size and position accuracy demand.In the past at machine tool or only have on the notch grinder of 5 emery wheels and process, not only work efficiency is low, and because moving axially, workpiece is easy to produce position accumulated error, on the punching bar of 1 meter long, process 27 sulculus time errors and sometimes reach 5～10 millimeters, on the punching bar of 3 meters long, process 79 sulculuses, error is sometimes greatly to using.

Summary of the invention

The utility model object is to provide a kind of punching bar Special grinding scouring machine, and this device can be realized on long punching bar and slotting quickly, efficiently and accurately.

The technical scheme that the utility model adopts is:

The utility model notch grinder comprises support, and the cuboid that described support is front openings is provided with manual draw bar after support;

On described support opening part, plane two ends are respectively provided with bearing block, installation shaft between two bearing blocks, and described axle is hollow shaft; On described axle, cover has some grinding wheels, between adjacent grinding wheel, separates with spacer sleeve; One end of axle connects with motor by shaft coupling; Described motor is arranged on motor base;

The lower plane of described support opening part arranges track, and described track adopts the rectilinear orbit of the rolling friction way of contact, and it is parallel with grinding wheel direction of rotation that track moves back and forth direction;

On described track, lay workbench, workbench can with track synchronizing moving, press strip is set on workbench, described workbench is laid when the work and clamping punching bar, described press strip is used for compressing punching bar.

The beneficial effects of the utility model are simple to operate, and operating efficiency is high.

Accompanying drawing 1 is the utility model notch grinder front schematic view;

Accompanying drawing 2 is the utility model notch grinder schematic rear view;

Accompanying drawing 3 is grinding wheel and spacer sleeve schematic diagram on the utility model slot grinding arbor;

Accompanying drawing 4 is the local enlarged diagram of punching bar.

In accompanying drawing, 1-support; 2-workbench; 3-bearing block; 4-grinding wheel; 5-shaft coupling; 6-motor; 7-motor base; 8-track; 9-press strip; 10-pull bar; 11-axle; 12-spacer sleeve; 13-punching bar.

The specific embodiment

As accompanying drawing, the utility model notch grinder comprises support 1, and the cuboid that described support is front openings adopts the mixed earth of reinforcing bar to build.Pre-buried pull bar 10 after support, holds pull bar need to mobile support time and drags;

On described support opening part, spacing between 3, two bearing blocks of bearing block is respectively installed is 1100 millimeters at plane two ends, and the axle 11 of 120 millimeters of diameters is installed therebetween, and described axle adopts hollow shaft, can weight reduction, be also convenient to spindle balance running;

On described axle, cover has 27 high accuracy and high balance quality emery grinding wheel sheet 4, between adjacent grinding wheel, separates with isometric spacer sleeve 12, and spacer sleeve can adopt grinding machine to process, to guarantee the spacing requirement of slotting of the applicable punching bar 13 of grinding wheel spacing;

One end of axle connects with motor 6 is flexible by elastic coupling 5; Described motor is arranged on the motor base 7 of mixed clay structure, and machine operation rotating speed is 1430 revs/min, and motor adopts button control start and stop;

The lower plane of described support opening part is laid two parallel orbits 8, and described track adopts the rectilinear orbit of the rolling friction way of contact, and it is parallel with grinding wheel direction of rotation that track moves back and forth direction;

Planing after workbench 2 use shaped steel, Plate Welding, common process equipment just can meet the required precision of workbench processing.Workbench is arranged on described track, and can with track synchronizing moving, workbench move back and forth can by manually easily realize;

Two press strips 9 with 26 half slots are set on workbench, and described workbench is laid when the work and clamping punching bar 13, and described press strip is used for compressing punching bar, can utilize press strip 26 punching bars of clamping once on workbench.

The utility model notch grinder has 27 grinding wheels, punching bar on notch grinder workbench once clamping location can grind at most 27 grooves, need grind 79 grooves as example take the punching bar of 3 meters long, when operation, a collection of punching bar of slot grinding just need have been located the work of punching bar total length slot grinding through multiple clamping on workbench simultaneously;

The operating process of the utility model notch grinder:

On workbench, make a part need the aligned in position grinding wheel group of fluting 26 longitudinal proper alignment of punching bar, utilize two press strips with 26 half slots to compress punching bar, make punching bar relatively fixing on workbench;

Starter motor, and drive grinding wheel High Rotation Speed, grinding wheel is contrary with workbench direction of propulsion near the linear velocity direction of punching bar slot grinding position;

By the artificial promotion platform 2 of track, make the punching bar of this clamping position enter successively slot grinding work, approximately 10 can complete the punching bar slot grinding work of a clamping position second;

After completing the punching bar slot grinding work of a clamping position, then workbench quick return is shut down;

On workbench, clamping is located punching bar again, makes punching bar aligned in position grinding wheel group to be slotted, and starts the slot grinding work of second clamping position;

Generally, through the slot grinding processing of 4 clamping positions, can all complete slot grinding work with 26 punching bars of a collection of slot grinding;
