Description

Automatic sizing device for aluminum rod sawing machine

technical field

The utility model relates to the technical field of mechanical equipment, in particular to an automatic length-setting device for an aluminum rod sawing machine.

Background technique

In recent years, with the development of the market, orders are increasing day by day, and the specifications of aluminum rods required by customers are also increasing. Most customers require the production of multiple aluminum rods with a fixed length between 4-5.8 meters. At present, the sawing system used in the traditional casting workshop is manual fixed-length sawing, that is, according to the customer's product length requirements, a ruler is welded on the corresponding length position on the sawing machine, and a baffle is set to achieve it. For example, the customer requires a length of 5 meters For aluminum rods, the operator will manually measure the size (3 people need to cooperate to complete it at the same time), weld a ruler on this position, and add a baffle, so that the operator's workload is heavy during manual sawing operations, and manual labor is required when feeding the rods. Pushing the aluminum rod under the saw blade will easily injure your fingers, and there is a certain potential safety hazard.

Utility model content

The technical problem to be solved by the utility model is to provide an automatic sizing device for an aluminum rod sawing machine that can quickly adjust the sizing length, improve sawing precision, reduce labor force, reduce labor intensity, and avoid potential safety hazards.

In order to solve the above problems, the automatic sizing device of the aluminum bar sawing machine described in the utility model includes a transmission track, a sizing mark, a frame, an adjusting screw, a polished rod, a reducer, a stepping motor, a cylinder and a sizing stop The board is characterized in that: the upper parts of the two sides of the transmission track are respectively provided with the scale marks, and the side of the transmission track is provided with the frame; the upper part of the frame is installed with the adjustment screw rod and the The polished rod; an encoder is installed at one end of the adjusting screw rod, and a driven sprocket is installed at the other end; the driven sprocket is connected to the driving sprocket arranged on the reducer through a chain; the reducer is connected to the The stepper motor; the polished rod and the adjusting screw rod are sleeved with a cavity measuring device bracket; the inside of the measuring device bracket is provided with the cylinder with the plunger downward, and the bottom end of the cylinder is connected with a The length baffle is erected on the conveying track; the connecting end of the length baffle is fixed to the lower end of the sizing device bracket through a pin shaft.

The polished rods are respectively arranged above and below the adjusting screw rod.

Compared with the prior art, the utility model has the following advantages:

1. Since the sizing device and the cylinder in the utility model are linked and connected, and the cylinder expands and contracts, according to the principle of the lever, the sizing device can be raised and lowered at different sizing marking positions, and the sizing can be quickly adjusted to improve sawing accuracy.

2. Since the sizing device bracket in the utility model moves left and right on the adjusting screw rod driven by the stepping motor, manual sizing is avoided, labor force is reduced, labor intensity is reduced, and potential safety hazards are avoided.
