Description

Technical Field

[0001] The utility model relates to the technical field of vertical machining center fixtures, in particular to a fixture used for a vertical machining center. Background Art

[0002] A vertical machining center refers to a machining center in which the spindle axis is arranged perpendicular to the worktable. It is mainly suitable for processing complex parts such as plates, discs, molds and small shells. It can complete processes such as milling, boring, drilling, tapping and cutting threads. During the use of the vertical machining center, in order to facilitate the processing of the workpiece, a fixture is required to clamp and fix the workpiece to be processed. For example, the current vertical machining center fixture generally uses an arc-shaped notch on the two-way clamping block to clamp and fix the circular workpiece during the clamping process of the circular workpiece. However, when clamping circular workpieces of different sizes, due to the fixed arc-shaped notch, the arc-shaped notch cannot completely fit with the outer wall of the circular workpiece, which makes the circular workpiece less stable after clamping. In addition, the extrusion process can easily cause the circular workpiece that is not fully matched to be damaged due to local force. Therefore, we propose a fixture for a vertical machining center to solve the above problems. Utility Model Content

The top of the support plate 5 is fixed with a bearing plate 6 through four connecting blocks. The top of the support plate 5 is rotatably connected to four rotating rods 7 through bearings. The top of the rotating rod 7 is fixed with a rotating plate 8. The top of the rotating plate 8 is movably connected to a moving rod 10 through a T-shaped shaft 9. One end of the moving rod 10 is fixed with a clamping block 11. The inner surface of the clamping block 11 is fixed with an anti-slip rubber block 18 for protecting the clamped workpiece, which can protect the clamped workpiece from damage caused by the clamping block 11, and the anti-slip rubber block 18 can It can increase the friction between the clamping block 11 and the surface of the clamped workpiece, so that the processed workpiece will be more stable after clamping. The clamping blocks 11 all slide on the top of the carrier plate 6. The top of the support plate 5 is provided with a driving mechanism 12 for driving the four rotating rods 7 to rotate synchronously. When using this vertical machining center fixture, after installing it in a suitable position, the circular workpiece to be processed can be placed on the carrier plate 6, and the motor is started to drive the driving mechanism 12 to rotate. Under the action of the driving mechanism 12, the four rotating rods 7 can be driven to rotate at the same time. After the rotating rods 7 rotate, they will drive the rotating plate 8 to rotate. When the rotating plate 8 rotates, the four moving rods 10 can be driven to move toward the center position of the supporting plate 6 with the cooperation of the T-shaped shaft 9. After the moving rods 10 move, the clamping blocks 11 can be driven to move. At this time, the four clamping blocks 11 can be used to clamp and fix the circular workpiece from four directions. When the angle of the support plate 5 needs to be adjusted, the motor can be started to drive the rotating shaft 3 to rotate forward and reverse.

When in use, the starting motor drives the transmission rod 1201 to rotate. With the cooperation of the driving gear 1202 and the four driven gears 1203, when the transmission rod 1201 rotates, it can drive the four rotating rods 7 to rotate at the same time, thereby saving production costs.

[0025] like Figure 4 As shown, in some embodiments, four guide grooves 13 are provided on the top of the supporting plate 6, and guide blocks 14 adapted to the guide grooves 13 are fixed to the bottom of the clamping block 11, which can guide and support the clamping block 11 so as to make it more stable during movement.
