Technical Field

The invention relates to the technical field of lathe workbenches, in particular to a turning tool structure applied to a lathe workbench.

Background

During large-scale production, the technical requirements on operators must be greatly reduced, and advanced equipment, tools, cutters, measuring tools and the like are effectively utilized to improve the stability and the identity of the product quality. The lathe mainly solves the automation of control and operation, ensures the identity of processed products, improves the utilization rate of the lathe on the basis and improves the production yield. And part of technical work is completed by professional engineering and process technicians. The requirements on the operation technique and skill are reduced. Reduce the quality and yield influence caused by operators. Therefore, in order to improve efficiency in a production line, it is necessary to effectively ensure the operating rate of each equipment and reduce the auxiliary time for tool changing, tool setting and the like.

Disclosure of Invention

The invention aims to provide a turning tool structure, which strengthens the fixing structure and the strength of the turning tool, avoids time waste caused by frequent tool changing, improves the workload of operators, and ensures the smoothness and the high efficiency of the work of a production line.

The turning tool structure comprises a turning tool holder and a turning tool, wherein the turning tool holder is provided with a circular plane, a fixed block for fixing the turning tool is arranged on the circular plane, and a U-shaped groove is formed in the middle of the fixed block; the turning tool comprises a tool body and a head, wherein the tool body is fixed in the U-shaped groove, the head extends towards the direction of the circle center of the turning tool seat from the U-shaped groove by protruding one end of the tool body outwards, the head is gradually inclined from inside to outside to form a cone structure, and one surface of the tool bit is inwards recessed to form an arc-shaped groove. The turning tool seat can be regarded as a thin cylinder structure, and a circular plane is a bottom surface of the turning tool seat. The arc-shaped groove enables the cutter head to form two cutting edges, so that the rigidity of the cutter head is guaranteed, and the cutting effect of the cutter head is enhanced.

Furthermore, one surface of the head part, which is inwards concave to form an arc-shaped groove, is in the same direction as the running direction of the lathe tool seat. One surface of the head, which is inwards concave to form an arc-shaped groove, is a cutting surface of the turning tool; when the turning tool is placed in the U-shaped groove, the placing direction of the cutting face is the same as the running direction of the tool apron, namely, the cutting face faces the workpiece during working.

Furthermore, the lathe tools are multiple and are uniformly arranged on the circular plane of the lathe tool seat in an annular array. A plurality of lathe tools have improved work efficiency.

Furthermore, the turning tools are different in distance from the circular plane. The cutting range of the turning tool on the workpiece is enlarged, and frequent tool setting is avoided.

Furthermore, the two side faces of the fixed block are oppositely provided with fixed holes for fixing the cutter body, and the cutter body is provided with through holes matched with the fixed holes. Utilize the bolt to pass fixed orifices and through-hole in being fixed in the U type recess of fixed block with the lathe tool, sound construction is difficult for droing.

Further, one side of the lathe tool seat back to the circular plane is provided with a rotating shaft, a rotating shaft supporting rod is arranged on the workbench, and the rotating shaft is assembled on the rotating shaft supporting rod and connected with an external motor. The turning tool seat is connected with the motor to rotate, so that high-speed cutting of the workpiece is realized.

Further, the circular plane of the lathe tool seat is perpendicular to the workbench so as to conform to the incoming direction of the workpiece and facilitate cutting.

According to the turning tool structure, the tool bit part is gradually inclined from inside to outside to form a cone structure, and one surface of the tool bit is recessed into an arc groove, so that the cutting effect of the tool bit is enhanced while the rigidity of the tool bit is ensured; the turning tool is fixed in the U-shaped groove of the fixing block of the tool apron, and the structure is stable. The turning tool structure greatly improves the working efficiency of a lathe assembly line, reduces the time for tool changing and tool setting, and reduces the workload of operators.
