Description

Technical Field

[0001] This utility model is a swing device, belonging to the field of swing devices for wire saw equipment. Background Technology

[0002] A wire saw is a cutting and processing device used for cutting hard materials such as stone, ceramics, silicon wafers, and magnetic materials. The oscillating mechanism, through a special transmission mechanism, reduces the contact area between the cutting wire and the workpiece, thereby improving chip removal and cooling, ensuring smooth cutting, especially for hard materials.

[0003] The existing swing mechanism of the wire saw equipment uses a swing frame directly driven by a motor. The swing frame is extended on the fixed frame, driven by two motors on both sides, and swings back and forth. The cantilever is large, the structure is bulky, difficult to assemble, and has poor precision. In addition, the single bearing box supports the rotation center, which has poor load-bearing capacity. After a certain period of time, the transmission structure is prone to deformation and wear due to fatigue. Utility Model Content

[0004] The purpose of this utility model is to provide a swing device to solve the problems of existing wire saw equipment swing devices that use a swing frame directly driven by a motor on a fixed frame with an extended structure of the swing fixed frame, driven by two motors on both sides for reciprocating swing. These devices have large cantilever arms, are bulky, difficult to assemble, have poor precision, and the single bearing box supports the rotation center with poor load-bearing capacity. After a certain period of time, the transmission structure is prone to deformation and wear due to fatigue.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a swing device, the structure of which includes a swing fixing frame;

[0006] A swing-type movable frame is movably mounted on the front end face of the swing-type fixed frame, with its top extending beyond the swing-type fixed frame and forming a drive unit;

[0007] A swing toothed row is horizontally provided at the top of the front end face of the swing fixing frame, and a swing rotation support bearing is provided in the lower middle part of the front end face of the swing fixing frame.

[0008] The front end face of the drive unit is provided with a motor. The reduction mechanism on the motor has a horizontally rearward rotating shaft that rotates through the drive unit. The motor shaft is equipped with a transmission gear that meshes with the rocking gear set. The rear end face of the drive unit is provided with at least one rocking limit mechanism.

[0009] The slewing support bearing includes a slewing outer ring and a fixed inner ring. The slewing outer ring is rotatably connected to the fixed inner ring. The slewing outer ring is fixedly connected to the slewing fixed frame by bolts, and the fixed inner ring is fixedly connected to the slewing movable frame by bolts.

[0010] Furthermore, in order to limit and adjust the swing, the swing limiting mechanism includes a fixed plate and a limiting rod. The limiting rod is horizontally disposed at the center of the rear end of the fixed plate. The fixed plate has at least one adjusting sliding hole, and the fixed plate is fixedly connected to the driving part by bolts through the adjusting sliding hole.

[0011] Furthermore, in order to prevent the swinging fixed frame from swinging excessively, during the swinging process of the swinging movable frame, the limiting rod will contact the top surface of the swinging fixed frame to limit its movement.

[0012] Furthermore, in order to perform swing positioning, the swing tooth row has an arc-shaped structure.

[0013] Furthermore, to improve the strength of the connection, the rocker toothed rack and the rocker fixing frame are connected by one of the following methods: bolt fixing or welding.

[0014] Furthermore, in order to make the outer ring rotate more smoothly, a number of positioning balls are provided at the connection between the outer ring and the fixed inner ring.

[0015] Furthermore, to improve the stability of the connection, the fixed inner ring and the swing fixing frame are fixedly connected by one of the following methods: bolting, welding, or integral molding.

[0016] Furthermore, to facilitate operation and control, an external control terminal is also included, which is electrically connected to the motor via wireless or wired means.

[0017] Furthermore, in order to adapt to the working methods of various wire saws, the swing angle range of the swing frame is ±10°.

[0018] Furthermore, in order to improve the overall rigidity, both the swing fixed frame and the swing movable frame are rectangular structures.

[0019] The beneficial effects of this utility model are: the use of a large-diameter slewing rotary support bearing in conjunction with a high-strength rigid slewing frame eliminates the need for an external rigid rotary support structure, resulting in a compact structure. The transmission method of the transmission gear driving the slewing gear rack is relatively simple, effectively improving the accuracy and stability of the transmission. Attached Figure Description
