DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-6 A parts positioning mechanism for stamping automobile parts, comprising a circular stamping platform 1, a circular track 2 is fixed to the outer side of the bottom of the circular stamping platform 1, and a plurality of vertical movable columns 3 are rotatably connected to the outer side of the circular track 2;

[0027] An L-shaped clamping block 4 is provided at one end of the top of the vertical movable column 3, and a moving mechanism for longitudinal movement of the L-shaped clamping block 4 is provided inside the vertical movable column 3. A lifting mechanism for vertical lifting of the L-shaped clamping block 4 is also provided inside the vertical movable column 3.

[0028] The moving mechanism includes a circular rotating tube 7, which is located inside the vertical moving column 3 and is rotatably connected to the vertical moving column 3 through a bearing. A circular lifting block 8 is slidably connected inside the circular rotating tube 7, and a circular rotating rod 9 is fixed to the top of the circular lifting block 8. A longitudinal moving column 5 is fixed to one end of the L-shaped clamping block 4 close to the vertical moving column 3, and a longitudinal fixed column 6 is slidably connected to the outer side of the longitudinal moving column 5.

[0029] A first bevel gear 10 is provided at the top of the circular rotating rod 9 and located inside the longitudinal fixed column 6. A second bevel gear 11 is meshed and connected to the top of the first bevel gear 10 and one end close to the L-shaped clamping block 4. A longitudinal threaded rod 18 is fixed to one end of the second bevel gear 11 close to the longitudinal moving column 5. The longitudinal threaded rod 18 passes through the interior of the longitudinal moving column 5 and is threadedly connected to the longitudinal moving column 5. The circular rotating tube 7 allows the circular lifting block 8 and the circular rotating rod 9 to rotate. The rotation of the circular rotating rod 9 is connected through the meshing of the first bevel gear 10 and the second bevel gear 11, allowing the longitudinal threaded rod 18 to rotate, thereby allowing the longitudinal moving column 5 to slide laterally inside the longitudinal fixed column 6, thereby allowing the L-shaped clamping block 4 to move longitudinally;

[0030] A plurality of vertical sliders are fixed to the outside of the circular lifting block 8, and a vertical slide groove is provided inside the circular rotating tube 7. The circular rotating tube 7 and the circular lifting block 8 are slidably connected through the cooperation of the vertical sliders and the vertical slide grooves. By setting the vertical sliders and the vertical slide grooves, the circular lifting block 8 can be vertically lifted inside the circular rotating tube 7, and then when the circular rotating tube 7 rotates, the circular lifting block 8 can rotate, and when the circular rotating tube 7 rotates, the circular lifting block 8 can be vertically lifted inside the circular rotating tube 7;

[0031] The lifting mechanism includes a vertical rotating shaft 16, which is located inside the vertical moving column 3 and is rotatably connected to the vertical moving column 3 through a bearing. A vertical threaded rod 17 is fixed to the top of the vertical rotating shaft 16, and the outer side of the vertical threaded rod 17 is threadedly connected to the vertical lifting column 15. The vertical threaded rod 17 is slidably connected to the vertical moving column 3.

[0032] The top of the vertical lifting column 15 is rotatably connected to the second oblique rotating rod 14, and one side of the top of the second oblique rotating rod 14 is rotatably connected to the first oblique rotating rod 13. The bottom of the first oblique rotating rod 13 is rotatably connected to the rectangular mounting seat 12, and the first oblique rotating rod 13 is close to one end of the vertical moving column 3 and is rotatably connected to the vertical moving column 3 through a pin shaft. The bottom of the rectangular mounting seat 12 is slidably connected to the longitudinal fixed column 6, and the longitudinal fixed column 6 is close to one end of the vertical moving column 3 and is slidably connected to the vertical moving column 3.

[0033] Here, the rotation of the vertical rotation shaft 16 enables the vertical threaded rod 17 to rotate, and the rotation of the vertical threaded rod 17 enables the vertical lifting column 15 to be vertically lifted and lowered inside the vertical movable column 3. The lifting and lowering of the vertical lifting column 15 is caused by the second oblique rotation rod 14 to enable the first oblique rotation rod 13 to rotate around the connection point between the first oblique rotation rod 13 and the vertical movable column 3, thereby enabling the rectangular mounting seat 12 to slide outside the longitudinal fixed column 6, thereby enabling the longitudinal fixed column 6 to be vertically lifted and lowered.

[0034] A T-shaped slider is fixed to the top of the longitudinal fixing column 6, and a T-shaped slot adapted to the T-shaped slider is provided at the bottom of the rectangular mounting seat 12. The longitudinal fixing column 6 and the rectangular mounting seat 12 are slidably connected by the T-shaped slot and the T-shaped slider. The cooperation of the T-shaped slider and the T-shaped slot enables the rectangular mounting seat 12 to slide longitudinally on the top of the longitudinal fixing column 6.

[0035] A dovetail slider is fixed to one end of the longitudinal fixed column 6 close to the vertical movable column 3. A vertical dovetail groove is provided inside the vertical movable column 3. The longitudinal fixed column 6 and the vertical movable column 3 are slidably connected by the dovetail slider and the vertical dovetail groove. The arrangement of the dovetail slider and the vertical dovetail groove enables the longitudinal fixed column 6 to be vertically raised and lowered inside the vertical movable column 3, so that the L-shaped clamping block 4 can be vertically raised and lowered.

[0036] Hand wheels are fixed to the bottom of the L-shaped clamping block 4 and the bottom of the vertical rotating shaft 16. Through the setting of the hand wheels, the L-shaped clamping block 4 and the vertical rotating shaft 16 can rotate inside the vertical movable column 3;

[0037] Through the setting of the moving mechanism and the lifting mechanism, the L-shaped clamping block 4 can move longitudinally and vertically, so that the L-shaped clamping block 4 can better fit the outer side of the special-shaped workpiece, thereby improving the positioning efficiency of the special-shaped workpiece. Through the rotation connection between the annular track 2 and the vertical moving column 3, the L-shaped clamping block 4 can rotate on the outer side of the special-shaped workpiece, thereby adjusting the clamping position of the L-shaped clamping block 4.

[0038] Working principle: When it is necessary to clamp a special-shaped workpiece, first push the vertical movable column 3 to rotate on the outside of the circular track 2 to adjust the clamping position of the L-shaped clamping block 4, and then rotate the handwheel through the vertical rotating shaft 16 to allow the vertical threaded rod 17 to rotate. The rotation of the vertical threaded rod 17 enables the vertical lifting column 15 to be vertically lifted inside the vertical movable column 3. The lifting and lowering of the vertical lifting column 15 is achieved through the second oblique rotating rod 14, which enables the first oblique rotating rod 13 to rotate with the connection between the first oblique rotating rod 13 and the vertical movable column 3 as the center of the circle. The rotation of the first oblique rotating rod 13 enables the rectangular mounting seat 12 to slide on the outside of the longitudinal fixed column 6, and enables the longitudinal fixed column 6 to be vertically lifted and lowered on one side of the vertical movable column 3, so as to adjust the clamping height of the L-shaped clamping block 4. During this process, the circular lifting block 8 can be vertically lifted and lowered inside the circular rotating tube 7.

[0039] Then, the handwheel is rotated through the circular rotating tube 7 to rotate the circular lifting block 8. The rotation of the circular lifting block 8 enables the circular rotating rod 9 to rotate inside the longitudinal fixed column 6. The meshing connection between the first bevel gear 10 and the second bevel gear 11 enables the longitudinal threaded rod 18 to rotate. The rotation of the longitudinal threaded rod 18 enables the longitudinal movable column 5 to slide inside the longitudinal fixed column 6, thereby enabling the L-shaped clamping block 4 to move longitudinally.
