Abstract

The invention discloses an automobile switch automatic quantitative grease filling machine. The quantitative grease filling machine comprises a control box, a large oil cylinder, a stepping motor, a transmission, a screw rod, a small oil cylinder, a grease valve and a grease filling body as well as an added guide plate, a guide rail and an adjusting knob, wherein the small oil cylinder is communicated with the grease filling body through the grease valve; the grease filling body also comprises an oil tube, a grease spraying port and a fiber optic sensor just facing to the grease spraying port; when a switch workpiece is put into the grease filling body, the fiber optic sensor obtains a triggering signal, and the stepping motor drives the screw rod through the transmission; the screw rod presses a small oil cylinder piston rod under the adjustment of the guide plate, the guide rail and the adjusting knob, therefore the grease enters the grease filling body through the grease valve; when the small oil cylinder piston presses and touches a baseplate, a magnetic switch inducts the triggering, thereby switching the stepping motor to rotate to drive the guide plate and the adjusting knob rod to reset, and meanwhile, the grease valve is switched; and the control box causes the large oil cylinder to rapidly supply grease to the small oil cylinder under the air pressure through an air valve, thereby pushing the adjusting knob to a guide plate surface.

Description

A kind of vehicle switch automatically quantitative grease-adder

Technical field

The invention belongs to technical field of automobile parts, particularly a kind of vehicle switch automatically quantitative grease-adder.

Background technique

In the existing technology, the switch key that uses on the automobile all has together the operation to the privileged site stuffing of switch key before assembling, and purpose is the quality of the smooth and easy and assembling that touches of the working life, the button that prolong switch.Existing equipment to the vehicle switch stuffing has no idea accurately to control for the amount of institute's fatten, needs more artificial subjectivity control, and this situation has influenced the efficient of producing in enormous quantities, also can't carry out stable control for the quality of stuffing link.

Summary of the invention

The purpose that provides of the present invention provides a kind of vehicle switch automatically quantitative grease-adder, solving the problem that the stuffing amount can't accurately be controlled in the existing switch stuffing operation,

Technological scheme of the present invention is, a kind of vehicle switch automatically quantitative grease-adder, said grease-adder comprise control box, large tank, stepper motor, speed changer, screw rod, small oil tank, grease valve and add oil body, and the guide plate of setting up, guide rail and adjusting pull,

Small oil tank through the grease valve with add oil body and be communicated with,

Saidly add that oil body also comprises oil pipe, spray fat mouth and over against the optical fiber transducer of spray fat mouth,

Put into when the switch workpiece and to add oil body, optical fiber transducer obtains trigger signal, and stepper motor drives screw rod through speed changer, and under the adjusting that guide plate, guide rail and adjusting are pulled, screw rod presses the small oil tank piston rod, and make grease get into and add oil body through the grease valve,

Touch base plate when small oil tank piston pressure, magnetic switch induction triggers, and switches the stepper motor revolution; Driving guide plate and the adjusting bar of pulling resets; Switch the grease valve simultaneously, control box makes large tank quick fuel feeding fat under air pressure promote to regulate and pull bar to the guide plate face to small oil tank through air valve.

Said grease-adder also comprises one near switch, injures to prevent personnel.

The present invention controls through the step-by-step impulse of stepper motor that to reach required grease quantitative, has realized that the high efficiency of stuffing operation and stuffing amount get automatically accurately control.
