Description

Technical Field

[0001] This utility model relates to the field of tool turrets, specifically a multi-process tool turret structure for a valve processing machine tool. Background Technology

[0002] In the field of machining, workpieces often need to undergo a variety of different processing operations, such as cutting, grinding, and drilling. Traditional processing equipment is usually single-function, and one piece of equipment can only complete one processing procedure. When multiple processing operations are required on a workpiece, the workpiece needs to be transferred between different pieces of equipment, which not only increases the labor intensity of workers, but also reduces processing efficiency.

[0003] Meanwhile, some existing multi-station machining equipment lacks flexibility in adjusting the positions of each machining station and the workpiece placement table, making it difficult to adapt to workpieces of different sizes and processing requirements, thus exhibiting significant limitations. Furthermore, the overall stability of the equipment needs improvement; it is prone to shaking during processing, affecting machining accuracy. Utility Model Content

[0007] As a further embodiment of this utility model: an adjustment assembly is fixedly connected to the upper central part of the support base, and the adjustment assembly includes a base plate for fixing to the upper part of the support base.

[0008] As a further embodiment of this utility model: a motor mounting base is installed in the middle of the upper surface of the base plate, a lead screw is installed at the drive end of the motor mounting base, and rails are fixedly connected to both the left and right sides of the upper surface of the base plate.

[0009] As a further embodiment of this utility model: a docking block is slidably connected to the upper part of the track, and a longitudinal adjustment mechanism is fixedly connected to the end of the docking block away from the track. A placement platform is installed on the adjustment part of the longitudinal adjustment mechanism.

[0010] As a further embodiment of this utility model: a lead screw cylinder is installed on the outer wall of the lead screw body, and the outer wall of the lead screw cylinder is fixedly connected to the bottom of the longitudinal adjustment mechanism, and the outer wall of the lead screw cylinder is fixedly connected to the inner side of the longitudinal adjustment mechanism.

[0011] As a further improvement of this utility model: support columns are fixedly connected to the left and right sides of the bottom of the support base, and the support columns are long strips.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model enables various processing operations on workpieces by installing tool holder three, tool holder two, and tool holder one on the rotating machine head. It eliminates the need to transfer workpieces between different devices, greatly improving processing efficiency and reducing the labor intensity of workers.

[0014] This utility model uses a motor to drive a lead screw to rotate, which, in conjunction with the lead screw cylinder, causes a sliding plate to slide along a slide rail. This allows for the adjustment of the lateral position of the mounting plate, mounting base, and rotating head, and the lateral position of the machining tool can be adjusted according to machining requirements.

[0015] This utility model uses a drive device on a motor mounting base to rotate a lead screw, which in turn drives a longitudinal adjustment mechanism to slide along a track, thereby adjusting the longitudinal position of the placement platform. This makes it easier to process workpieces of different sizes, and its structure is more optimized and its design is more reasonable. Attached Figure Description
