Description

Safe chassis

Technical Field

The utility model belongs to the technical field of the vibration dish, specifically speaking relates to a safe chassis.

Background

The vibrating disc is an auxiliary feeding device for automatic assembly or automatic processing machinery. A vibrating device is arranged on a base plate of the vibrating plate to provide a certain vibration frequency for the base plate, the base plate transmits vibration to a hopper of the vibrating plate, and parts in the hopper are vibrated to ascend along a track of the hopper, so that automatic feeding is realized.

Most of the existing chassis utilize an electromagnet as a vibration device, for example, a side-pulling chassis disclosed in the publication No. CN 213621858U, which includes a base provided with a mounting seat and a top cover connected with a fixed block, wherein the end surface of the upper part of the mounting seat is fixedly connected with the electromagnet, the electromagnet is provided with an armature seat, the fixed block is fixedly connected with an armature which is matched with the armature seat and drives the top cover to move, and the side-pulling chassis has a simple structure and stable performance.

However, for example, the above-mentioned patent, the technical scheme that the chassis is driven to vibrate by the electromagnet has a certain potential safety hazard, because the electromagnet arranged on the chassis needs to be electrified in the whole process when working, a small amount of electric sparks are sometimes released, especially when flammable and explosive materials exist in the working environment where the vibration disc is located, safety accidents are very easy to cause, and meanwhile, the electromagnet directly connected to the power supply also causes the chassis to have a risk of electric leakage.

Disclosure of Invention

To the problem that there is the potential safety hazard in adopting the electro-magnet to drive chassis vibration at present, present provide following utility model.

The safe chassis comprises a base, a spring piece and a top cover, wherein the base and the top cover are connected through the spring piece, the chassis is further provided with a pneumatic vibrator capable of driving the top cover to vibrate, and the chassis is not in direct contact with any electrified part.

Preferably, the pneumatic vibrator is mounted on a base.

Preferably, the pneumatic vibrator is arranged on the outer side surface of the base, so that the pneumatic vibrator is convenient to disassemble.

Preferably, the pneumatic vibrator is a pneumatic turbine vibrator, and can bring stable and efficient vibration to the base.

Preferably, install the rubber foot on the base, make the base more stable.

Advantageous effects

The utility model provides a pair of safe chassis changes vibrating device into pneumatic vibrator by the electro-magnet, has avoided the production and the electric leakage phenomenon of electric spark to take place, has improved the security of vibration dish in the use.

Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the embodiments.

As shown in fig. 1, it is the utility model discloses preferred safe chassis, including base 1, top cap 2, spring leaf 4, the one end of spring leaf 4 is being installed on the base 1, fixed mounting is going up top cap 2 on the other end of spring leaf 4, and the hopper part of vibration dish is being installed to top cap 2 upside, be equipped with on the base 1 and drive top cap 2 and take place the pneumatic vibrator 3 of vibration, top cap 2 further drives the hopper and takes place the vibration to realize automatic material loading. The pneumatic vibrator 3 is not in contact with any current, so that the problem of safety accidents caused by the release of electric sparks is solved.

Further, the pneumatic vibrator 3 is installed on the base 1, the pneumatic vibrator 3 transmits vibration to the spring strip 4 through the base 1, and the spring strip 4 transmits vibration to the top cover 2.

Further, the pneumatic vibrator 3 is vertically arranged on the outer side surface of the base 1 through bolts, and the pneumatic vibrator 3 can be replaced and adjusted at the position without detaching the top cover 2 of the chassis.

Further, the pneumatic vibrator 3 is a pneumatic turbine vibrator, an eccentric turbine is arranged in the pneumatic turbine vibrator, the pneumatic turbine vibrator rotates on the track at a high speed to generate a high-power centrifugal force, and stable and efficient vibration frequency is provided for a vibrator chassis.

Further, install three rubber foot 5 that the annular distributes on the base 1, rubber foot 5 adopts the rubber of higher strength to make and forms, can improve base 1's stability.

The above embodiments are some, but not all embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention, and the technical contents claimed by the present invention have been recorded in the claims.
