Description

Device for screwing two-way joint of oil pipe

Technical Field

The utility model relates to an automobile brake system technical field specifically is an oil pipe two-way joint screws up device.

Background

The oil pipe is a brake hard pipe in the automobile brake system, and brake fluid is transmitted to wheels through a pipeline to realize the brake function. The connection between the two brake hard tubes is realized by a copper two-way joint. After an oil pipe produced by an automobile accessory factory is bent and molded, an oil pipe joint needs to be assembled at one end of the copper two-way joint, torsion is tightened, and after the oil pipe is sent to a host factory, the other end of the copper two-way joint is screwed with the other oil pipe joint to realize pipeline connection. At present, no tool is used for screwing an oil pipe joint and a copper two-way joint, an open spanner is held by the left hand, and a bayonet of the open spanner is clamped into the hexagonal surface of the copper two-way joint; the right hand holds a fixed value wrench, and a bayonet of the fixed value wrench is clamped on the hexagonal surface of the oil inlet pipe joint; the open end wrench applies force in the anticlockwise direction, the fixed value wrench applies force in the clockwise direction until the customized wrench makes a crack, the torque value is reached, and therefore the copper two-way joint is screwed down. Because there is not the frock when screwing up copper two-way joint, the cooperation of leaning on people's left and right hands is beaten the torsion, has following problem:

the open end spanner of left hand needs to be parallel with the definite value spanner of right hand, when crooked nonparallel appears when going out power, leads to oil pipe joint's hexagonal head to twist smooth tooth easily, and is higher to technical staff's technical requirement.

Because the open spanner of left hand needs to open into copper two-way joint, simultaneously, the definite value spanner of right hand needs the card oil inlet pipe to connect, need aim at the screens when the card, and the takt is slow.

When torque is applied, the left hand and the right hand need to be matched to exert force, and if the strength of a technician is insufficient and the strength of a woman is weak, the woman cannot do the work.

SUMMERY OF THE UTILITY MODEL

The utility model provides an oil pipe two-way connection screws up device combines the shape that the two-way connection connects, and the design can telescope the hexagonal hole that the two-way connection connects and screw up the frock. Meanwhile, the tool is horizontally welded to one corner of the first workbench, so that the tool is fixed to the first workbench. The tool is simple in design, the operation of workers is more convenient, and the production beat is greatly improved.

The utility model provides an oil pipe two-way joint screws up device, is including screwing up frock and first workstation, it is fixed to set up to screw up the frock on the working face of first workstation, it is provided with the hole to screw up the frock, the opening orientation of hole the first workstation outside, hole inner wall profile and the cooperation of two-way joint surface profile of oil pipe. When the utility model works, a worker only needs to insert the two-way joint at one end without the oil pipe into the screwing tool by the left hand, and at the moment, the two-way joint can only be inserted or taken out in the horizontal direction and can not rotate in the vertical direction; the right hand of a worker holds the constant-value torque wrench to screw the oil pipe joint, and the two-way joint and the oil pipe joint are screwed tightly. And after screwing, taking the part out of the fixing tool.

Preferably, the outer surface of the two-way joint is of an outer hexagonal structure, the inner hole is of an inner hexagonal structure, and the outer surface of the screwing tool is cylindrical. The inner hole is slightly larger than the external size of the two-way joint, the two-way joint can conveniently and smoothly enter and exit the inner hole, the structure is simple, the two-way structure is convenient to be matched with a torque wrench, and the cost is low.

Preferably, the upper surface of the first workbench is of a quadrilateral structure, and the screwing tool is arranged at one corner of the first workbench. Simple structure, the oil pipe of being convenient for is placed at the workstation edge, is convenient for screw up the operation.

Preferably, the screwing tool is welded on the first workbench. The tightening tool is fixed on the workbench, and the tool is simple in design and process, firm in installation and low in cost.

Specifically, the inner hole axis is parallel to the edge of the first workbench.

Preferably, the device further comprises a second workbench, the second workbench is arranged beside the first workbench, the second workbench is used for storing the oil pipe to be screwed, and the first workbench is used for storing the screwed oil pipe. The two-way joint is convenient for placing screwed and unscrewed oil pipes, is convenient for placing the two-way joint of the oil pipe more quickly, is simpler to operate, and greatly improves the production takt.

The utility model has the advantages that:

1. because the two-way joint cannot rotate in the vertical direction by screwing the tool, the two-way joint can be screwed only by one fixed-value wrench, the step of taking the open wrench by the left hand is saved, one hand is vacated, and the left hand and the right hand do not need to be matched, so that male and female workers can be competent for the work.

2. Because the two-way joint is fixed in the tool, force is exerted by the right hand in the vertical direction when the torque force is exerted, and the phenomenon that the teeth slip when the torque force is exerted on the oil pipe joint is greatly reduced.

3. The operation is simpler, and the production takt is greatly improved.
