[0032] The auxiliary loading and unloading mechanism 40 has a carrier 41 and a lifting drive assembly 42. The lifting drive assembly 42 drives the carrier 41 to move linearly up and down relative to the chuck 31. The carrier 41 can carry the workpiece 60 and drive the workpiece 60 to move. By setting up the auxiliary loading and unloading mechanism 40 composed of the carrier 41 and the lifting drive assembly 42, during operation, the lifting drive assembly 42 drives the carrier 41 to move linearly up and down relative to the chuck 31, so that the carrier 41 is transferred to the chuck 31 or the workpiece 60 is removed from the chuck 31, realizing automated auxiliary loading and unloading with high efficiency.

[0033] The carrier 41 is provided with a positioning hole 43, in which the workpiece 60 can be placed. The chuck 31 can extend upward into the positioning hole 43.

[0034] The carrier 41 comprises a base 44 and a positioning seat 45 which is detachably mounted on the base 44, the positioning hole 43 is arranged on the positioning seat 45, the lifting driving assembly 42 drives the carrier 41 to move up and down linearly, the lifting driving assembly 42 has at least one lifting driving unit 421, the driving end of the lifting driving unit 421 is connected with the carrier 41, specifically, three lifting driving units 421 are arranged around the outside of the positioning hole 43, and the lifting driving unit 421 is a pneumatic cylinder; by arranging the positioning seat 45 which is detachably mounted on the base 44, different positioning seats 45 can be replaced to adapt to different workpieces 60, and the universality is good.

[0035] The base 44 is provided with a mounting hole 441 which is in communication with the positioning hole 43, the positioning seat 45 is detachably mounted in the mounting hole 441, and a plurality of positioning grooves 442 are distributed around the mounting hole 441 on the upper surface of the base 44, the positioning grooves 442 are in communication with the mounting hole 441, and a plurality of positioning blocks 451 are radially outwardly protruded on the circumferential side wall of the positioning seat 45, and the positioning blocks 451 extend into the positioning grooves 442; by arranging the positioning grooves 442 and the positioning blocks 451, the positioning blocks 451 are embedded in the positioning grooves 442, so that the positioning seat 45 is conveniently mounted on the base 44, and the cooperation of the positioning grooves 442 and the positioning blocks 451 can limit the rotation of the positioning seat 45 relative to the base 44, and the stability is good.

[0036] The machine table 10 is further provided with a rotary driving mechanism 50, the clamping mechanism 30 is mounted on the driving end of the rotary driving mechanism 50, and the rotary driving mechanism 50 drives the clamping mechanism 30 to rotate; by arranging the rotary driving mechanism 50, the rotary driving mechanism 50 drives the clamping mechanism 30 to rotate, so that the angle of the workpiece 60 is adjusted, and the drilling mechanism 20 can drill different angle positions on the workpiece 60.

[0037] The rotary driving mechanism 50 has a first driving module 51 and a second driving module 52, the clamping mechanism 30 is mounted on the driving end of the first driving module 51, the first driving module 51 drives the clamping mechanism 30 to rotate around the Z-axis, the first driving module 51 and the auxiliary feeding and discharging mechanism 40 are both mounted on the driving end of the second driving module 52, the second driving module 52 drives the first driving module 51 to rotate around the X-axis or the Y-axis, and specifically, the lifting driving unit 421 is mounted on the driving end of the second driving module 52 through the mounting frame 46; by arranging the first driving module 51 and the second driving module 52 with different rotary axes, the angle of the workpiece 60 can be adjusted in different directions, the adjustment range is larger, and the applicability is better.

[0038] The chuck 31 is provided with a positioning sleeve 311 that can extend upward into the workpiece 60 through a through hole 61. The positioning sleeve 311 is surrounded by several elastic blocks 312, which can deform radially. When the elastic blocks 312 abut against the inner wall of the through hole 61, the positioning sleeve 311 clamps the workpiece 60. Specifically, the positioning sleeve 311 and the chuck 31 are integrally formed. The clamping mechanism 30 also includes a telescopic rod 32 and a telescopic drive unit 33. The telescopic rod 32 is movable... The telescopic drive unit 33 drives the telescopic rod 32 to move up and down, and the upper end of the telescopic rod 32 is provided with a radially outward protrusion 321. When the telescopic rod 32 drives the protrusion 321 to move down, the protrusion 321 pushes the elastic block 312 outward, so that the elastic block 312 clamps the workpiece 60. When the telescopic rod 32 drives the protrusion 321 to move up, the protrusion 321 releases the push on the elastic block 312, so that the elastic block 312 moves radially inward and releases the workpiece 60.

[0039] like Figure 8 As shown, in the second embodiment, the difference from the first embodiment is that the chuck 31 has several vertically extending movable columns 34, and the clamping mechanism 30 also has a clamping drive unit 35. The movable columns 34 are arranged in a ring, and the movable columns 34 are detachably connected to the drive end of the clamping drive unit 35 by screws. The movable columns 34 can extend upward into the through hole 61 on the workpiece 60. The clamping drive unit 35 drives the movable columns 34 to move closer together or disperse. When the movable columns 34 abut against the inner wall of the through hole 61, the movable columns 34 clamp the workpiece 60. Specifically, the clamping drive unit 35 can be a finger cylinder. By using detachable movable columns 34, different movable columns 34 can be replaced to adapt to different workpieces 60, resulting in good versatility.

[0040] The working principle of this utility model is as follows: The external robot first places the workpiece 60 in the positioning hole 43. The lifting drive unit 421 drives the carrier 41 to move downward relative to the chuck 31. The carrier 41 moves the workpiece 60 downward. The positioning sleeve 311 on the chuck 31 extends upward into the through hole 61 on the workpiece 60. When the lower end of the workpiece 60 abuts against the upper end face of the chuck 31, the workpiece 60 stops moving downward and is transferred to the chuck 31. The telescopic drive unit 33 drives the telescopic rod 32 to move downward. When the telescopic rod 32 moves the protrusion 321 downward, the protrusion 321 pushes the elastic block 312 outward to disperse, so that the elastic block 312 clamps the workpiece 60. The drilling mechanism 20 drills a hole in the workpiece 60. After drilling is completed, the elastic block 312 releases the workpiece 60. The lifting drive unit 421 drives the carrier 41 to move upward relative to the chuck 31. The carrier 41 lifts the workpiece 60 so that the workpiece 60 moves upward and gets off the chuck 31. The robot takes away the workpiece 60.

[0041] In summary, the utility model discloses a supplementary upper and lower mechanism 40 is set up, when feeding, first, workpiece 60 is placed on supplementary upper and lower mechanism 40, then workpiece 60 is driven by supplementary upper and lower mechanism 40 and moves up and down relative to chuck 31, workpiece 60 is transferred to chuck 31 and is clamped, when discharging, chuck 31 loosens workpiece 60 that completes drilling, and supplementary upper and lower mechanism 40 removes workpiece 60 that completes drilling from chuck 31, thereby reach the effect of supplementary workpiece 60 feeding and discharging, avoid the collision of chuck 31 and the material taking part on the external mechanical hand, make workpiece can normally feed and discharge.

[0042] The above is only the preferred embodiment of the utility model, and does not limit the utility model, so any modification, equivalent replacement, improvement etc. of the above embodiment according to the technical actuality of the utility model still belongs to the range of the technical scheme of the utility model.
