The top limiting unit, the bottom limiting unit and the side limiting unit can position and clamp the workpiece in multiple directions, avoid the workpiece from slipping off, and improve the processing accuracy, reliability and workpiece consistency.

[0030] In this example, by driving the second rotating seat to rotate through the driving motor, the workbench can be driven to rotate to form an inclination angle, which is convenient for the operator to install the workpiece and keep away from the drill bit above the workbench, thus improving safety.

[0031] In this example, a pair of top limiting units, bottom limiting units and side limiting units are provided, which can clamp two groups of workpieces at the same time. Two groups of drill bits can be provided at the top of the machine tool to process simultaneously, improving production efficiency.

[0032] In this embodiment, it is further set that the top limiting unit includes a top limiting block 71 and a first adjusting bolt 72. The top limiting block is bolted to the workbench; the first adjusting bolt penetrates through the top limiting block. The knob end of the first adjusting bolt is located outside the top limiting block. The head of the first adjusting bolt faces the workpiece. The knob end of the first adjusting bolt is provided with anti-slip threads, which can increase the friction to avoid slipping. By turning the first adjusting bolt, the top shaft hole of the workpiece can be positioned and clamped. The diameter of the thick section of the head of the first adjusting bolt is larger than the diameter of the top shaft hole of the workpiece, and the diameter of the end of the head of the first adjusting bolt is smaller than the diameter of the top shaft hole of the workpiece.

[0033] In this embodiment, it is further set that the bottom limiting unit includes a bottom limiting block 81 and a second adjusting bolt 82. The bottom limiting block is bolted to the workbench; the second adjusting bolt penetrates through the bottom limiting block. The knob end of the second adjusting bolt is located outside the bottom limiting block. The head of the second adjusting bolt faces the workpiece. The knob end of the second adjusting bolt is in a hexagonal shape, which is convenient for rotating the second adjusting bolt. By turning the second adjusting bolt, the bottom shaft hole of the workpiece can be positioned and clamped. The diameter of the thick section of the head of the second adjusting bolt is larger than the diameter of the bottom shaft hole of the workpiece, and the diameter of the end of the head of the second adjusting bolt is smaller than the diameter of the bottom shaft hole of the workpiece.

[0034] In this embodiment, it is further set that the side limiting unit includes a side limiting block 91 and an adjusting bolt three 92. The side limiting block is bolted to the workbench. The adjusting bolt three penetrates through the side limiting block. The knob end of the adjusting bolt three is located outside the side limiting block, and the head of the adjusting bolt three faces the workpiece. The knob end of the adjusting bolt three is in a hexagonal shape, which is convenient for rotating the adjusting bolt three. By turning the adjusting bolt three, the side shaft hole of the workpiece can be positioned and clamped. The diameter of the thick section at the head of the adjusting bolt three is larger than the diameter of the side shaft hole of the workpiece, and the diameter of the end of the head of the adjusting bolt three is smaller than the diameter of the side shaft hole of the workpiece.

[0035] In this embodiment, it is further set that the surface of the bottom plate is arrayed with grooves 10. The grooves can facilitate the discharge of cutting fluid, avoid the accumulation of residual cutting fluid, improve work efficiency and processing quality, help maintain the cleanliness of the working environment, and extend the service life.

[0036] In this embodiment, it is further set that a moving seat 11 is provided below the bottom plate. The grooves are arrayed with mounting holes, and mounting bolts 12 pass through the mounting holes to mount the bottom plate on the moving seat.

[0037] In this embodiment, it is further set that the moving seat is sleeved on the moving track 13, and the moving seat can translate along the direction of the moving track, so that the workpiece on the workbench can be moved under the drill bit, which is convenient for subsequent processing.

[0038] Embodiment 2:

[0039] In this embodiment, as Figure 1-2 shown, Figure 2 For one of the machined workpieces, shaft holes are provided on the top, bottom and side of the workpiece. The contour surfaces of the top and bottom of the workpiece are uneven. If a clamping plate is used to clamp the workpiece, the clamping force is too small, and the clamping plate cannot firmly clamp the workpiece; if the clamping force is too large, it will damage the end face of the workpiece. Therefore, it is more reasonable to use the top limiting unit, the bottom limiting unit and the side limiting unit to position and clamp the workpiece.

[0040] Since the adjusting bolt one, the adjusting bolt two and the adjusting bolt three respectively perform multi-directional positioning and clamping on the top, bottom and side of the workpiece, and the workpiece is suspended, when the drill bit processes the workpiece, it will not damage the workbench.

[0041] The working principle of the processing tooling with an end face limiting structure is that the operator operates the controller, drives the second rotating seat to rotate through the driving motor, drives the workbench to rotate to form an inclination angle, pre-adjusts the stroke of the first adjusting bolt, aligns the shaft hole at the top of the workpiece and inserts it into the head of the first adjusting bolt. Subsequently, turn the second adjusting bolt so that the head of the second adjusting bolt is inserted into the shaft hole at the bottom of the workpiece, and then turn the third adjusting bolt so that the head of the third adjusting bolt is inserted into the shaft hole on the side of the workpiece. After positioning the workpiece in multiple directions, operate the controller to reset the workbench, close the hatch, and process the workpiece with the top drill bit.
