Abstract

A dustproof structure of a tool machine comprises a tool machine and a flow guide part disposed in the tool machine. A holding space is arranged in the tool machine for holding a tool shaft and a flow guide part, the holding space is further provided with an air inlet section and an air exhausting section communicated with the air inlet section, the tool machine is provided with an air inlet communicated with the air inlet section and an air outlet communicated with the air exhausting section, and an actuating part is connected to the tool shaft outside the air outlet. When the tool shaft which is in linkage with the actuating part operates, the flow guide part guides external air to enter the air inlet section from the air inlet, and when the air is guided to the air exhausting section, the air is exhausted out towards the actuating part arranged outside the air outlet so as to prevent dust generated by the actuating part against entering the exterior of the tool machine from the air outlet when the tool machine runs, thereby ensuring the tool machine to run stably and prolonging service life of the tool machine.

Description

The dustproof construction of toolroom machine

Technical field

The utility model relates to a kind of dustproof construction of toolroom machine, relates in particular to a kind of dustproof construction that reaches the toolroom machine of dustproof effect when toolroom machine turns round at toolroom machine inner generation air-flow.

Background technology

Since the invention of electro-motor begins, since several centuries constantly progress and development for the mankind bring great facility in life, by the Large Electric motor of initial industrial use, be applied to small-sized electric motors such as daily living article, toolroom machine so far.

The present common toolroom machine of industry, as grinder etc., mainly all be to drive by motor to turn round, and be easy to generate dirt bits in the running and influence the cleaning of workpiece or environment, therefore, toolroom machine on the market all has additional dust exhaust apparatus mostly now, the dirt bits that produced when being used for the cleanout tool machined.Shown in TaiWan, China M245007 patent case, it discloses a kind of exhaust apparatus of pneumatic type grinder, mainly comprise a body, this body side face side direction form up and down side by side one on an extension and a lower extension, should go up extension and be provided with the air inlet through hole, and one air inlet tube is set in this air inlet through hole, and this lower extension is provided with a dust gathering arrester in the below, and the opening part in dust gathering arrester is provided with an abrasive disk, and this abrasive disk is provided with air suction opening, and be provided with a dust leg that connects dust bag in this lower extension side, when this air inlet tube importing gas makes this grinder running, this abrasive disk can be introduced via the air suction opening on this abrasive disk carrying out the dust that grinding work produced, and by the lower extension that this dust gathering arrester enters this body, import via dust leg again this dust leg end in the sheathed dust bag.

In addition, and for example shown in No. 517618 patent case of TaiWan, China, it discloses a kind of exhaust structure of pneumatic type grinder, be provided with an emery wheel that possesses air suction opening, and a dust cover is set in emery wheel upper end, this dust cover and motor shell are affixed, and in the indoor movable vane air pressure motor group that is installed with of the shell of motor shell, and motor shell one side also one extend adjacent air inlet pipe and escape pipe, and on the turnover tracheae, also be installed with an air intake valve group and an exhaust noise silencing group respectively, passing in and out on the tracheae and establishing the room that can be installed with choke valve and adjust button, extend opposed both wing portions in the end face one simultaneously simultaneously, can set firmly a mobilizable inlet plate machine; Wherein, extend a tank that can articulate the blast pipe of motor shell in this dust cover, and tank extends to dust cover connecting leg portion and locates, and in the motor shell blast pipe, establish the conduit that without exception is the L shape, and a water conservancy diversion plate is established in the conduit lower end, upwards discharge by the wind-force that makes movable vane air pressure motor group by exhaust vent, and this conduit lower end extends to nearly dust cover connecting leg portion outlet front end, and the exhaust that makes motor can form a river outlet with the exit of dust cover connecting leg portion, and the dirt bits after the grinding can be absorbed fast because of bigger air-out, and be installed with an adjustment button at motor shell blast pipe and escape pipe adjoiner, this adjustment button has a hollow-out parts and a wall portion, and can control the path of giving vent to anger, and can select by the escape pipe exhaust or by the blast pipe exhaust.

By above-mentioned patent case as can be known, toolroom machine is removed the mode of dirt bits at present, all is at toolroom machine side installing dust leg, when making the toolroom machine running, can carry out dust suction work simultaneously.Yet, the dirt bits that processing is produced upwards enter toolroom machine inside via abrasive disk and dust gathering arrester, the airflow direction that is subjected to dust suction again influences and imports dust leg, because path and nonocclusive passage that the dirt bits are advanced, when the dirt bits upwards enter this toolroom machine inside, can't guarantee that all dirt bits all can be attracted to dust leg, moreover, the motor of toolroom machine, also can cause air-flow during the cylinder running, when causing the dirt bits upwards to enter this toolroom machine inside, but be deposited in easily among each slit of grinder, even can escape into the cylinder internal that the drive abrasive disk rotates at a high speed, cause the damage of toolroom machine inner body.

The utility model content

Main purpose of the present utility model is to solve above-mentioned defective, can completely cut off the dirt bits when making the toolroom machine running and enter toolroom machine inside, avoids toolroom machine in dust discharge, and outside dirt bits are inhaled into toolroom machine with air-flow and cause toolroom machine to damage.

For achieving the above object, the utility model proposes a kind of dustproof construction of toolroom machine, it mainly possesses a toolroom machine is arranged, wherein, this toolroom machine inside has an accommodation space so that a tool spindle and a conducting element to be set, this accommodation space also is provided with an air inlet section is communicated with this air inlet section with one exhaust section, and this toolroom machine is provided with the air inlet that is communicated with this air inlet section, and the exhaust outlet that is communicated with this exhaust section, and this tool spindle connects in this exhaust outlet outside and establishes an actuator, when this actuator running of this tool spindle interlock, this conducting element guides extraneous gas to this air inlet section by this air inlet, and gas is guided to this exhaust section, and discharge towards the actuator that is arranged at this exhaust outlet outside.

Because toolroom machine that the utility model disclosed discharges gas by inside towards the actuator of this exhaust outlet, the dirt bits that this actuator added produce man-hour can't enter this toolroom machine by this exhaust outlet, the cleaning that not only can keep toolroom machine inside, more can avoid the part of toolroom machine inside to be subjected to the influence of dirt bits and damage, improve the service life of toolroom machine whereby.
