Abstract
A handheld grinding machine mainly comprises a machine base and a handle which is connected with the machine base, and a motor is installed inside the machine base; a on-off key is installed on the handle; the on-off key and the motor are in electric connection with an external power supply through power lines; a grinding device which is installed inside a protective cover is installed above the machine base; the grinding device comprises a cam which is connected with a rotary shaft of the motor; the cam is connected with a transmission rod provided with a grinding head through a connection rod; and the transmission rod vertically penetrates through a guide sleeve which is fixed on the machine base. The handheld grinding machine is simple in structure, flexible and convenient to operate, low in manufacturing cost, and wide in application range, can guarantee speed and quality of grinding, keeps consistency of casting machining, is beneficial for mass production of castings, reduces labor intensity of workers greatly, and improves whole production efficiency.
Description
Technical field
The utility model relates to a kind of sander, relates in particular to a kind of hand sander of foundry goods being carried out grinding process.
Background technology
The foundry goods that any casting technique casts out all in various degree have flash, burr, must be through just entering manufacturing procedure after the treatment process such as polishing; Traditional polishing mode is to adopt artificial way, the workman utilizes instrument one to hammer into shape and polishes, so, not only workman's labour intensity is large, and the speed of polishing is slow, efficient is low, and the foundry goods through so polishing, and its uniformity is relatively poor, easily following process is impacted, thereby affect proceeding of whole production; Even existing polishing machine, its volume is large, complex operation, and all there is your limitation in the maintenance for the little burr minor issue that occurs in the processing of small workpiece or the practical operation.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of scope of application extensive, the effective a kind of hand sander of polishing.
The purpose of this utility model is achieved by the following technical solution: comprise that mainly one is built-in with support, a handle that links to each other with described support of motor; Be provided with an on ﹠ off switch on the described handle; Described on ﹠ off switch and described motor are electrically connected by power line and external power source; Described support top is equipped with a sanding apparatus that is arranged in the over cap; Described sanding apparatus comprises a cam that links to each other with the rotating shaft of described motor; Described cam links to each other with a drive link with grinding head by connecting rod; Described drive link vertically passes the fairlead that is fixed on the support.
Described drive link front end offers a radial screw bore, and this screwed hole connects a hold-down bolt; Described hold-down bolt end compresses the grinding head that an end stretches into described drive link; The surface of described grinding head is provided with screw thread.
Described grinding head is arranged on the outside of over cap.
The beneficial effects of the utility model are: it simple in structure, flexible and convenient operation; The cost of manufacture of device itself is low, and is applied widely; Can guarantee speed and the quality of polishing, keep the uniformity of Mechanical processing of casting, help to produce in batches foundry goods; And greatly reduce workman's labour intensity, improve whole production efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of sanding apparatus described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: as shown in Figure 1, 2, comprise that mainly one is built-in with support 1, a handle 2 that links to each other with described support 1 of motor; Be provided with an on ﹠ off switch 3 on the described handle 2; Described on ﹠ off switch 3 is electrically connected by power line 4 and external power source with described motor; Described support 1 top is equipped with a sanding apparatus that is arranged in the over cap 5; Described sanding apparatus comprises a cam 7 that links to each other with the rotating shaft 6 of described motor; Described cam 7 links to each other with a drive link 9 with grinding head 10 by connecting rod 8; Described drive link 9 vertically passes the fairlead 11 that is fixed on the support 1.
Described drive link 9 front ends offer a radial screw bore 12, and this screwed hole 12 connects a hold-down bolt 13; Described hold-down bolt 13 ends compress the grinding head 10 that an end stretches into described drive link; When grinding head 10 fractures maybe need to change, by degree of tightness hold-down bolt 13, just can change grinding head; The surface of described grinding head is provided with screw thread, the effect that can strengthen polishing.
Described grinding head 10 is arranged on the outside of over cap 5.
In concrete operations, plugged, one holds handle 2, holds support 1, keeps the stable of entire machine, then grinding head 10 is aimed at required Working position, opens on ﹠ off switch 3, the motor entry into service; This moment, the rotating shaft of motor was rotated, and with moving cam 7 runnings and the drive by connecting rod 8, so that drive link 9 moves up and down fast with 10 of polishings, began to remove the action of burr, flash; Treat that workpiece machines, closing switch key 3, the whole operation of deenergization is finished.
Certainly, above-mentioned explanation is not limitation of the utility model, and this real utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
