Description

A precision machining positioning mechanism for a horizontal machining center

Technical Field

The utility model relates to the field of horizontal machining centers, in particular to a precision machining positioning mechanism for a horizontal machining center.

Background Art

A horizontal machining center refers to a machining center machine tool in which the spindle axis is set parallel to the worktable. It can process larger parts and can also perform indexing and rotary processing. It is most suitable for multi-process processing such as milling, drilling, boring, reaming, tapping, two-dimensional and three-dimensional curved surfaces of multiple working surfaces of parts. It has the good performance of completing box hole systems and plane processing in one clamping, and is also particularly suitable for turning and boring processing of box holes. It is widely used in the automotive, internal combustion engine, aerospace, home appliances, general machinery and other industries. The horizontal machining center has high precision and adopts high-precision linear guides and ball screws to ensure the processing accuracy and surface quality and good stability. The large components of the machine tool are made of high-strength materials to ensure the rigidity and stability of the machine tool and are not easily deformed during the processing. The horizontal machining center needs to position and install the workpiece being processed during precision machining, which requires the use of a positioning mechanism.

After searching, a precision machining positioning mechanism for a horizontal machining center with a publication number of CN219725380U is disclosed, which specifically discloses a precision machining positioning mechanism for a horizontal machining center, including a shell, a control cabinet and a clamping plate. A control cabinet is provided on one side of the shell, a processing device is provided inside the shell, and the clamping plate is provided below the processing device. One side of the clamping plate is movably connected to the side plate, one end of the clamping plate is connected to one end of a support rod through a fastener, a third drive motor is provided on the support rod, and the third drive motor is fixedly connected to a drive gear through an output shaft. The second drive motor drives the support rod to rotate through a hydraulic cylinder through the output shaft, and the rotation of the support rod drives the parts to rotate through the clamping plate, so as to adjust the direction of the parts, facilitate the processing device to process other positions of the parts, save time and effort, and reduce work efficiency.

In the above patent, only the housing, control cabinet, clamping plate, side plate and support rod are used to realize the rotation of the support rod through the output shaft through the hydraulic cylinder. The rotation of the support rod drives the parts to rotate through the clamping plate, so as to achieve the purpose of adjusting the direction of the parts, which is convenient for the processing device to process other positions of the parts, saving time and effort and reducing work efficiency. However, during the use of the precision machining positioning mechanism of the horizontal machining center, when the workpiece is positioned and installed for processing, it is necessary to change the processing position of the workpiece in the face of different precision machining requirements. The fixed machining head cannot fully meet the different machining requirements, and the installed workpiece needs to be disassembled to meet the precision machining requirements of the horizontal machining center by changing the position or direction of the workpiece. Such a method of frequently changing positions is not only cumbersome, but also inconvenient to use in the horizontal machining center, and it is easy to affect the precision of the precision machining of the horizontal machining center.

Therefore, it is necessary to invent a horizontal machining center precision machining positioning mechanism to solve the above problems.
