Abstract

A wire saw drive mechanism for driving a wire saw to move in a reciprocating manner includes a tension unit having a first reciprocating device connected to the wire saw; and a power unit having a second reciprocating device connected to the wire saw. The first and second reciprocating devices move in a first direction and in a second direction which is 180 degrees from the first direction. A tension force is constantly exerted upon the first reciprocating device to pull it towards the first direction. If a force pulling the second reciprocating device towards the second direction is greater than the tension force, the first and second reciprocating devices move simultaneously in the second direction. When the force disappears, the first and second reciprocating devices move simultaneously in the first direction subject to the applied tension force. Thereby the wire saw is driven to move in a reciprocating manner in the first and second directions.

Description

Wire saw drive structure

The invention relates to a wire saw driving structure of a wire sawing machine, in particular to a mechanism for applying a pulling force at one end and applying or releasing a force at a time interval greater than the tensioning force at the other end, so that the wire saw can reciprocate. .

When the wire saw is in operation, the wire saw will reciprocate to achieve the sawing action, and the wire saw can be driven in many ways. For example, the Republic of China Patent No. 482091 "Swing Structure of Wire Saw Machine" is a motor-driven linkage mechanism that allows the linkage mechanism to swing up and down the swing arm so that the saw blade can be reciprocated up and down; or the Republic of China Patent No. M495286 "Improvement of the transmission structure of the wire saw machine", the case uses a slide rail combined with a crank to drive the wire saw.

However, the former case is generally the use of the linkage mechanism to drive the wire saw, so there is the disadvantage of requiring a large volume and occupying space, and the structure is relatively complicated. In addition, the previous case is to reciprocally apply a pulling force on both ends of the wire saw to drive the wire saw movement, and it is impossible to tighten the wire saw with constant force, which may loosen the wire saw and fail to completely cut the object.

In order to improve the above-mentioned deficiency, the present invention provides a wire saw driving structure for a wire saw to drive a wire saw to reciprocate to cut an object, including:

a tensioning unit having a first reciprocating mechanism coupled to the wire saw, the first reciprocating mechanism reciprocating between a first direction and a second direction in a corresponding direction, the first reciprocating mechanism being constant Receiving a tensioning force in the first direction; a power unit having a second reciprocating mechanism coupled to the wire saw, the second reciprocating mechanism being located on the same axis as the first reciprocating mechanism, and The first direction and the second direction reciprocate.

When the second reciprocating mechanism receives a force in the second direction, and the force is greater than the tensioning force, the first reciprocating mechanism and the second reciprocating mechanism simultaneously displace in the second direction, When the force disappears, the first reciprocating mechanism and the second reciprocating mechanism are simultaneously displaced by the tensioning force in the first direction, thereby driving the wire saw in the first direction and the second Reciprocating between directions.

Further, the first reciprocating mechanism is a first pneumatic cylinder mechanism.

Further, the first pneumatic cylinder mechanism includes a first piston, the first piston is pivotally connected to a first strut, the first strut is sleeved with a first collar, and a first pressing member is extended. The first collar is inserted into the first strut and the first strut is pressed against the first strut, thereby forcing the wire saw between the first strut and the first strut.

Further, the second reciprocating mechanism is a second pneumatic cylinder mechanism.

Further, the second pneumatic cylinder mechanism includes a second piston, the second piston is pivotally connected to a second strut, the second strut is sleeved with a second collar, and a second pressing member is extended. The second collar is inserted into the second strut and the second strut is pressed between the second strut and the second collar.

Further, the second reciprocating mechanism includes a motor, a lead screw is coupled to the rotating shaft of the motor, a sliding member is coupled to the lead screw, and a pressing mechanism is coupled to the sliding member. To fix the wire saw.

Further, the second reciprocating mechanism includes a motor, an eccentric wheel is coupled to the rotating shaft of the motor, a slider is abutted by the eccentric wheel, and the wire saw is locked on the slider.

The effect of the invention is:

1. The wire saw has one end constantly applying a tensioning force, and the other end is applied with an interval time greater than a pulling force to reciprocate the wire saw. The wire saw is tensioned throughout the operation, so the object can be completely cut.

2. The pneumatic cylinder is used to drive the wire saw to reciprocate, the structure is simple, and the overall mechanism is easily miniaturized.
