Description

Automatic avoiding and welding tool for forklift oil tank

Technical Field

The invention relates to the technical field of welding of forklift fuel tanks, in particular to an automatic avoiding welding tool for a forklift fuel tank.

Background

The welding requirement of oil tank is high, and the oil leak more easily more that welded joint is more, and in welding process, the oil tank is fixed through positioning and clamping device, and welding robot's welder need accomplish welding operation around the oil tank round trip movement, and when welder reachd positioning and clamping device position, welder and positioning and clamping device produced the interference for welder pause welding continues the welding after the switching position, causes the welding seam to break, and the welding seam is discontinuous, thereby influences welding qualification rate and efficiency.

Disclosure of Invention

The invention aims to provide an automatic avoiding welding tool for a forklift oil tank, and aims to solve the technical problem.

In order to solve the technical problems, the invention adopts the following technical scheme:

the utility model provides an automatic welding frock of dodging of fork truck oil tank, includes fixed baseplate, fixture base, a plurality of location and dodges cylinder and controller, fixed baseplate is fixed to be set up on the mounting base, fixture base is fixed to be set up in the middle of fixture base's top surface, and the oil tank is located fixture base's top surface in the middle of, oil tank frock base top surface all around is fixed to be equipped with a plurality of cylinder base, a plurality of location is dodged the cylinder and is fixed to be set up on the cylinder base, and fixes a position and dodge the flexible end of cylinder and respectively towards each side and the top surface of oil tank, a plurality of location is dodged the cylinder and all is connected with controller electrical.

Preferably, the bottom of oil tank is equipped with the oil tank bottom plate, the oil tank bottom plate surpasss the side of oil tank, be equipped with a plurality of on the fixture base in the oil tank bottom plate edge outside and compress tightly the cylinder, compress tightly cylinder and controller electrical connection.

Preferably, the number of the positioning avoiding cylinders is more than 3.

Preferably, flexible buffer sleeves are sleeved at the end parts of the telescopic ends of the avoiding cylinders.

Preferably, a pressure sensor is arranged in a flexible buffer sleeve at the end part of the telescopic end of the avoidance cylinder, and the pressure sensor is electrically connected with the controller.

The invention has the beneficial effects that:

1. the avoidance cylinder arranged in the invention can avoid when the welding manipulator works to prevent interference, so that the welding manipulator can continuously weld, a weld joint is formed at one time, the welding quality is greatly improved, and the welding efficiency is improved.

2. The air cylinder arranged in the invention can effectively prevent the welding quality from being influenced by the movement of the oil tank during welding operation.

3. The flexible buffer sleeve is arranged at the front end of the avoiding cylinder, so that the end part of the cylinder can be prevented from scratching an oil tank, the length of the avoiding cylinder can be reasonably fed back and adjusted by the built-in pressure sensor, and the situation that the oil tank is unstable due to the fact that the avoiding cylinder extends too long and the oil tank has too large pressure or too short extension is avoided.

Detailed Description

In order to make the technical means, the original characteristics, the achieved purposes and the effects of the invention easily understood, the invention is further described below with reference to the specific embodiments and the attached drawings, but the following embodiments are only the preferred embodiments of the invention, and not all embodiments. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention.

Specific embodiments of the present invention are described below with reference to the accompanying drawings.

As shown in fig. 1-3, an automatic welding frock of dodging of fork truck oil tank, dodging cylinder 5 and controller including fixed baseplate 3,

fixture base

4, 5 location, fixed baseplate 3 is fixed to be set up on mounting base 1, fixture base 4 is fixed to be set up in the middle of fixed baseplate 3's top surface, and oil tank 2 is located in the middle of fixture base 4's top surface, the fixed 5 cylinder bases that are equipped with of 4 top surfaces of fixture base around

oil tank

2, 5 location dodge cylinder 5 and fix and set up on the cylinder base, and the flexible end of dodging cylinder 5 in the location is respectively towards each side and the top surface of oil tank 2, and the flexible tip of dodging cylinder 5 all overlaps and is equipped with flexible buffer sleeve, be equipped with pressure sensor in the flexible buffer sleeve, 5 location dodge cylinder 5, pressure sensor all with controller electrical connection.

The bottom of oil tank 2 is equipped with oil tank bottom plate 7, oil tank bottom plate 7 surpasss the side of oil tank 2, be equipped with 3 cylinders 6 that compress tightly on the frock base 4 in the 7 marginal outsides of oil tank bottom plate, compress tightly cylinder 6 and controller electrical connection.

Before use, position coordinate parameters are input into a controller according to the size of an oil tank 2 and the size of a welding manipulator, when the welding manipulator is used, a tool base 4 is fixedly arranged on a mounting base 1 through a fixed base 3, the whole tool can move along with the mounting base 1 and stops moving after reaching a target station, the oil tank 2 to be welded moves above the welding station along with a moving device, at the moment, the controller controls 5 avoiding cylinders 5 to extend to support and fix the oil tank 2 from all directions, meanwhile, 3 pressing cylinders 6 press an oil tank bottom plate 7 from different directions to avoid the movement of the oil tank 2 in the welding process, the controller controls an automatic welding manipulator to move along a to-be-welded seam in the three-dimensional direction to weld, when the welding manipulator moves to the position of the avoiding cylinder 5 quickly, the controller controls the avoiding cylinder 5 at the position to return to prevent the avoiding cylinder 5 from blocking the welding manipulator, avoid interfering to can guarantee that the welding seam is complete in succession for the incessant welding forward of welding manipulator, improve welding efficiency and welding quality, the welding of this department is accomplished the back, and the welding manipulator moves forward, dodges cylinder 5 and extends once more and withstands oil tank 2.
