Abstract

The invention discloses a pneumatic transmission device for a suspended spot welding machine, which is mainly composed of a film cylinder and a connecting rod lever bolt barrel. The cylinder film is clamped between a cylinder cover and a cylinder seat. A circular push plate is installed in the concave surface of the gas cylinder film. A spring is sleeved on a fixed rod. A through groove is opened in the bolt barrel axially, and the bolt handle passes through the through groove and is fixed on the moving rod perpendicular to the axis of the bolt barrel. The device omits a piston cylinder, thereby reducing the volume and weight of the pneumatic transmission device of the spot welding machine, reducing the cost of manufacturing, and being flexible and reliable in operation.

Description

The pneumatic actuator of hanging spot-welder

The present invention is to be on March 10th, 92 applying date, and application number is 92108053.0, and name is called dividing an application of " band transformer hanging spot-welder ".

The present invention relates to a kind of pneumatic actuator of hanging spot-welder, by diaphragm cylinder, lever, connecting rod, bolt tube switch constitute.

In technique known, what the pneumatic actuator of hanging spot-welder adopted is piston type cylinder, and this has increased the weight of the volume of welding machine itself undoubtedly.

The object of the present invention is to provide a kind of volume little, in light weight, easy to use and reliable, be convenient to the maintenance, processing is easy, cost is low, is used for the pneumatic actuator of hanging spot-welder.

Purpose of the present invention can reach by following measure: pneumatic actuator is made of diaphragm cylinder, connecting rod, lever and bolt tube switch.The cylinder film (4) of disc-shape is installed between circular cylinder cap (3) cylinder block (1).The convex surface of cylinder film is towards cylinder head, this is the one side of air inlet just also, at the center of cylinder film concave surface circular push pedal (6) is housed, lever (20) one ends are equipped with bearing, bearing top circle and push pedal are tangent, the phase tangent plane is in the central position of cylinder film, the other end of lever with decide bar (10) and be connected, spring (12) is sleeved on to be decided on the bar (10), between spring abutment (11) and block (13), bolt tube profile is a cylindrical body, in step through-hole is arranged, inner via hole is coaxial with bolt tube cylindrical, leave one section groove vertically on the bolt tube, radially also leave groove, radially the length of groove is equivalent to 1/4 of bolt tube external diameter, axial pass trough interconnects and forms the groove at right angle each other with groove radially, and the bolt handle passes groove and is fixed on the moving bar (16) perpendicular to bolt tube axis.

Purpose of the present invention can also reach by following measure: the manufactured materials of cylinder film is a polyurethane, also can adopt rubber, accompanies nylon embedding hair net in the middle of film, to increase its intensity.

The drawing of accompanying drawing of the present invention is described as follows:

Fig. 1 is the pneumatic actuator perspective view of hanging spot-welder.

Fig. 2 is that the pneumatic actuator I of hanging spot-welder is to diagrammatic sketch.

Be described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the pneumatic actuator perspective view of hanging spot-welder.Fig. 2 is that Fig. 1 " I " is to view.This pneumatic actuator is made of diaphragm cylinder, lever, connecting rod, bolt tube switch.The cylinder film (4) of disc-shape is installed between cylinder cap (3) and the cylinder block (1), the manufactured materials that constitutes the diaphragm cylinder film is polyurethane or rubber, the centre sandwiches multilayer nylon embedding hair, couple together by the circumference of a plurality of screws (2) along cylinder, circular clamping plate (8) are housed and convex surface is equipped with pressing plate (5) at the concave surface of cylinder film (4), connect with screw (7), clamping plate pressing plate and film are concentricity, adorn a push pedal (6) in the center of clamping plate (8), lever (20) is fixed on the cylinder block (1) by mandrel (19), one end of lever is by mandrel (21) connection bearing (22), bearing and push pedal are tangent, tangent position just in time is in the center of cylinder, the other end of lever by axle (9) with decide bar (10) and link to each other.Connect the formation connecting rod by the straight line line of deciding bar (10), spring abutment (11), spring (12), block (13), bolt tube (14), bolt handle (15), moving bar (16), joint (17).Bolt tube (14) profile is a cylindrical body, leave trapezoidal interior circular hole with bolt tube cylindrical coaxial line, stomidium towards spring (12) is little, this end with decide bar (10) by the axle (9) link to each other, link stopper (13) is spirally connected to be fixed on and decides on the bar (10), it can be by the pressure of threaded adjusting spring, and spring (12) is enclosed within deciding on the bar (10) between spring abutment (11) and the block (13).At bolt tube middle part, one section groove is arranged, groove is left one section vertically, then, change 90 ° and radially leave, radially the length of groove is equivalent to 1/4 shape such as the rifle croze of periphery, the groove that bolt handle (15) passes on the bolt tube is fixed on the moving bar (16), moving its diameter of the part of bar within the bolt tube matches with bolt tube endoporus, the bolt tube, and the combination of bolt handle and moving bar constitutes bolt tube switch.The other end of moving bar is connected with joint (17), by mandrel (18) rocking arm of joint and spot welding machine is coupled together, the effect of connecting rod has two, when bolt handle during in a position, air inlet film is heaved in the cylinder, push pedal heads on bearing, makes this end lever reach, and moves behind the other end of lever, by moving behind the connecting rod drive rocking arm, the two poles of the earth close up up and down, and length of spring compressed is after stopping the supple of gas or steam, the spring reduction, two electrodes open, thereby have realized the circulation of welding, when the position of bolt handle at b, the reach of promotion rocking arm, the distance of two electrodes is magnified, and the open ultimate range of two electrodes is 6-10 times of proper functioning distance, offers convenience to welding job.

The present invention has following advantage and effect:

1, owing to adopted diaphragm cylinder to replace piston type cylinder, makes this device body Long-pending reduce, weight saving, flexible operation is reliable, easy to maintenance.

2, manufacturing processing is simple, cost is low.
