Abstract
The creation of the utility model relates to a movable vacuum early-warning device. The adopted technical scheme is as follows: the movable vacuum early-warning device comprises a vacuum platform, a vacuum filter is connected with a pressure detection switch through a pipeline, and the pressure detection switch is connected with the vacuum platform through a pipeline; after being connected in parallel, a buzzer alarm and an alarm indicator light are connected with the pressure detection switch, and a power start switch is respectively connected with a power indicator light and the pressure detection switch; a chargeable battery supplies power to the movable vacuum early-warning device. Aimed at a machining site where movable vacuum accessories are used by a numerically controlled machine tool, the movable vacuum early-warning device can effectively monitor and early warn the state of vacuum in use, and can monitor the pressure of a vacuum inlet, the working pressure in the vacuum platform and the blockage of a vacuum pipeline and the vacuum filter in real time. When a vacuum system is abnormal to cause the decrease of vacuum absorption capability, the movable vacuum early-warning device can give the clear audible and visual alarm and a corresponding alarm prompt, so the occurrence of machining accidents caused by vacuum can be effectively prevented.
Description
Technical field
The invention belongs to field of machining, is specifically related to a kind of mobile vacuum precaution device.
Background technology
It is at home and abroad just to bring into use that Digit Control Machine Tool adopts pallet changer processing recent years, be mainly used in the Digit Control Machine Tool type of interchangeable and turnover plate type workbench, for batch production requirements facilitates with adding man-hour, most of users install vacuum adsorption type frock (vacuum platform) on portable pallet changer.The problem existing is, in process, when the phenomenons such as leak source, release, the inner obstruction of vacuum system or inlet pressure fluctuation appear in part and frock, will make the part of processing become flexible or float, cause part to be subjected to displacement or initial point lose, make part overproof, scrap and even cause skill peace accident.
In addition, use vacuum platform to add man-hour at lathe, often have the operation of processing sheet or cutting parts, very easily workpiece is cut leakage, make smear metal and greasy dirt by vacuum suction line, so vacuum line often stops up, and affect vacuum pressure.
Summary of the invention
In order to overcome the above problems, the invention provides a kind of use state for vacuum effectively to monitor and early warning, the mobile vacuum precaution device of monitoring vacuum inlet pressure that can be real-time.
The technical scheme that the invention adopts is: mobile vacuum precaution device, comprise vacuum platform, and vacuum filter is connected with pressure detection switch by the road, and pressure detection switch is connected with vacuum platform by the road; After buzzer siren and alarm lamp parallel connection, be connected on pressure detection switch, power initiation button connects respectively power supply indicator and pressure detection switch; Rechargeable battery provides power supply for precaution device.
The beneficial effect of the invention is: 1. the invention can be installed on all kinds of Digit Control Machine Tools, and the pressure state of vacuum platform is carried out to examinations and early warning.2. after the invention is analyzed for the present situation of Digit Control Machine Tool pallet changer and vacuum system, be provided with pressure detection switch, and be provided with pressure limit, when vacuum pressure in vacuum platform be-when 0.06Mpa～-0.1Mpa, for normal operating conditions, can, being adsorbed on platform of processing parts safety, in the time that vacuum pressure is 0～-0.06Mpa, be inoperative pressure, must and alarm, thereby can ensure product quality and reduce scrappage.3. the invention is provided with vacuum filter, has prevented that smear metal and greasy dirt from entering pipeline, and then has prevented vacuum line blockage problem.
The invention is used the processing site of mobile vacuum annex for Digit Control Machine Tool, use state for vacuum can effectively be monitored and early warning, monitoring vacuum inlet pressure that can be real-time, vacuum platform internal work pressure, vacuum line and vacuum filter stopping state.When vacuum system occurs extremely, while causing vacuum suction ability to weaken, can send in time obvious sound and light alarm and corresponding alarm, therefore can effectively avoid the processing accident causing because of vacuum cause to occur.
Brief description of the drawings
Fig. 1 is the structural representation of the invention.
Fig. 2 is the electrical schematic diagram of the invention.
Detailed description of the invention
As shown in Figure 1, mobile vacuum precaution device, comprises vacuum platform (8), and vacuum filter (1) is connected with pressure detection switch (6) by the road, and pressure detection switch (6) is connected with vacuum platform (8) by the road; After buzzer siren (2) and alarm lamp (3) parallel connection, be connected to pressure detection switch (6) upper, power initiation button (5) connects respectively power supply indicator (4) and pressure detection switch (6); Rechargeable battery (7) provides power supply for precaution device.
The electrical schematic diagram of the invention as shown in Figure 2.
When use, vacuum filter is connected with vacuum system, and pressure detection switch is connected with vacuum platform by pipeline, can detect the pressure in vacuum platform in real time.When vacuum pressure in vacuum platform be-when 0.06Mpa～-0.1Mpa, for normal operating conditions, can, being adsorbed on platform of processing parts safety, in the time that vacuum pressure is 0～-0.06Mpa, be inoperative pressure, must and alarm, thereby can ensure product quality and reduce scrappage.
