DETAILED DESCRIPTION

[0011] In order to further understand the technical solution of the present invention, the technical solution of the present invention is now clearly and completely described through embodiments in combination with the accompanying drawings.

[0012] like Figure 1-4 The utility model vertical machining center combined drilling and tapping device comprises a basic clamping and positioning device, an inherited clamping and positioning device, and corresponding pressing components.

[0013] The basic clamping and positioning device includes a basic base plate 1, three spaced-apart equal-height blocks 2, and a basic positioning device. The three equal-height blocks 2 are fixed to the opposite sides and the middle of the basic base plate by screws 6 respectively.

[0014] In this example, the basic positioning device includes side positioning posts 3-1, corresponding to opposite ends of each workpiece 5-1 and fixedly connected to the two side equal-height blocks 2, and end positioning posts 3-2, corresponding to one end of each workpiece 5-1 and fixedly connected to the base plate 1. In this embodiment, the basic clamping and positioning device can simultaneously perform three-point positioning on a group of eight workpieces for machining.

[0015] The clamping assembly 4 of the basic clamping and positioning device includes a clamping block 4a that clamps each adjacent workpiece, a bolt 4c connected between the equal-height block in the middle of the foundation base plate 1 and the clamping block 4a, and a nut 4b connecting the bolt 4c and the clamping block 4a. In this example, the clamping block 4a has a side-opening U-shaped slot 4a1, through which the clamping block is inserted into the bolt.

[0016] The inherited clamping positioning device includes a stacking base plate 8 and a combined positioning device. The combined positioning device includes a plurality of positioning pins 9 fixedly connected to the stacking base plate 8 and a double-headed positioning pin 10. Each positioning pin 9 corresponds to one end of each corresponding workpiece 5-2 and one end of one side thereof, forming a three-point positioning for each corresponding workpiece 5-2.

[0017] The double-ended locating pins include a double-ended locating pin 10a, which plugs into the corresponding positioning holes 7 of the stacking base plate 8 and the base base plate 1, and a boss 10b fixedly connected to the center of the double-ended locating pin 10a. The boss 10b radially protrudes from the perimeter of the double-ended locating pin and has a cross-section larger than the corresponding inner diameter of the positioning hole 7. The positioning holes 7 are located in the center of the opposite ends of the base base plate and the stacking base plate, respectively. The positioning holes 7 of the base base plate and the stacking base plate adaptively cooperate with the double-ended locating pin 10a to position the base base plate and the stacking base plate. The thickness of the protruding portion of the boss is equal to or less than the thickness of the contour block 2.

[0018] The pressing block of the pressing assembly 4 used to inherit the clamping and positioning device is connected with the bolt through its through hole. The rest of the structure and connection method of the pressing assembly are similar to those of the basic clamping and positioning device.

[0019] During operation, the base plate is fixed to the workpiece processing workbench, and 8 workpieces 5-1 are placed on the equal-height blocks horizontally with the equal-height blocks, and one side and one end of each workpiece are respectively abutted against the positioning columns on the corresponding side and one end, and then all the workpieces are pressed onto the base plate in pairs using the clamping components, so that a group of 8 workpieces can be processed simultaneously.

[0020] After the processing of the group of workpieces is completed, the clamping assembly is released, the group of workpieces that have been processed are removed, and the superimposed base plate is stacked on the equal height block of the base base plate. The opposite ends of the double-headed locating pins are inserted into the positioning holes of the base base plate and the superimposed base plate, and the base base plate and the superimposed base plate are fixedly connected with bolt fasteners 11. The boss of the double-headed locating pin limits the double-headed locating pin or further strengthens the equal height positioning support of the base base plate and the superimposed base plate. The corresponding 8 workpieces 5-2 of another group are placed on the superimposed base plate, and each corresponding workpiece is respectively abutted against the locating pins on one side and one end thereof. Finally, the clamping assembly is used to clamp and fix each pair on the superimposed base plate, and the corresponding processing is carried out. Its inherited clamping and positioning device can also process corresponding different workpieces.

[0021] In another embodiment of the present invention, the clamping assembly used to inherit the clamping positioning device has the same structural composition and connection method as the clamping assembly of the basic clamping positioning device. The positioner includes positioning blind holes respectively opened in the basic base plate and positioning through holes of the superimposed base plate, as well as cylindrical double-headed positioning pins connected between the positioning through holes of the superimposed base plate and the basic base plate. The depth of the positioning blind hole of the basic base plate is slightly smaller than the thickness of the basic base plate, and the bottom wall of the blind hole limits the cylindrical double-headed positioning pin. That is, the double-headed positioning pin does not need to be provided with a boss. The remaining structure and corresponding connection method and usage method of the combined drilling and tapping device of the vertical machining center in this example can be similar to the above-mentioned embodiment.

[0022] Those skilled in the art will appreciate that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention. The embodiments described are merely a portion of the embodiments of the present invention, not all of them. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
