Detailed Description
To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the attached drawings in the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Referring to fig. 1 and 2, an extension table of a milling machine, which clamps and positions a workpiece 7 through a positioning hole on the workpiece 7, includes: the positioning device comprises a machine tool base plate 1, a positioning pin 2 and a clamping assembly 3, wherein a positioning pin hole 4 is formed in a fixed position on the machine tool base plate 1, and a positioning groove 5 which is collinear with the positioning pin hole 4 in the X direction is formed in the machine tool base plate 1. When a workpiece 7 is clamped, two positioning holes are preprocessed in the X direction on the workpiece 7, the two positioning pins 2 are respectively inserted into the two positioning holes, meanwhile, the two positioning pins 2 penetrate through the workpiece 7 to be matched with the positioning pins 2 and the positioning grooves 5 on the machine tool base plate 1, and therefore the X direction of the workpiece 7 coincides with the X direction of the machine tool base plate 1 after two-point positioning.
The machine tool base plate 1 is also provided with a plurality of threaded holes 6, and the clamping assembly 3 can be in threaded connection with the threaded holes 6 so as to clamp the workpiece 7 on the machine tool base plate 1. The distances between the adjacent threaded holes 6 in the X direction and the Y direction on the machine tool base plate 1 are the same, and then the workpiece 7 is clamped and completely clamped on the machine tool base plate 1 through the clamping assembly 3, so that one plane of the workpiece 7 is completely attached to the machine tool base plate 1. Complete freedom degree limitation on the workpiece 7 is completed, the workpiece 7 is clamped quickly and simply, and the workpiece 7 can be machined directly without aligning the workpiece 7.
The positioning pin 2 is arranged at the center of the machine tool base plate 1 in the Y direction, so that the workpiece 7 is clamped at the center of the machine tool base plate 1 approximately, and the clamping range of the machine tool base plate 1 is enlarged.
Referring to fig. 3 and 4, the clamping assembly 3 includes: locking screw 31, limit screw 32 and clamping block 33. Before clamping, the limiting screw 32 can be adjusted to the height required by clamping in advance, the clamping block 33 is aligned with the workpiece 7, and finally the locking screw 31 is aligned with the threaded hole 6 on the machine tool substrate 1 to lock the clamping block 33. Stop screw 32 flip-chip is on pressing from both sides tight piece 33, makes stop screw 32's nut one end and machine tool substrate 1 contact, can avoid stop screw 32 just to influence spacing effect on the screw hole 6 on machine tool substrate 1 like this, increases stop screw 32 and machine tool substrate 1's area of contact, increases the stability of pressing from both sides tightly. Since the threaded holes 6 on the machine tool base plate 1 are arranged at a certain distance, it cannot be guaranteed that the threaded holes 6 exist at corresponding positions where the locking screws 31 are not located, the clamping block 33 is further provided with a through groove for allowing the locking screws 31 to slide, so that the locking screws 31 can be adjusted in position, and the locking screws 31 can be quickly aligned with the threaded holes 6 on the machine tool base plate 1.
