Description

Technical Field

[0001] The utility model relates to the technical field of conveying mechanisms, and particularly relates to a workpiece transmission mechanism for a five-axis gantry machining center. Background Art

[0002] The five-axis linkage machining center, also known as the five-axis machining center, is a machining center with high scientific and technological content and high precision, specially used for machining complex curved surfaces. This machining center system has a pivotal influence on industries such as a country's aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment, etc. There is an existing patent for a workpiece transmission mechanism for a five-axis gantry machining center, with the patent publication number CN214444931U. It includes a mechanical housing, on the outer wall of the mechanical housing is provided a first motor, and on the inner wall of the mechanical housing is provided a gear. The gear is connected to the first motor, and on the outer wall of the gear is provided a chain conveyor main body. Inside the fixed block is provided a protective baffle, and on the outer wall of the fixed block is provided a second motor, and the second motor is connected to the protective baffle. This workpiece transmission mechanism for a five-axis gantry machining center is provided with protective baffles on all four sides of the machining platform for placing workpieces. Thus, when machining the workpiece, by starting the second motor, the second motor is used to drive the protective baffle to rotate and make the protective baffle stand upright. The four protective baffles protect the four sides of the workpiece, thereby reducing the waste chips generated during workpiece machining from flying onto the surface of the chain conveyor main body, playing a protective role for the chain conveyor main body and ensuring the service life of the chain conveyor main body.

[0003] Regarding the above related technology, the inventor believes there are the following defects: This workpiece transmission mechanism for a five-axis gantry machining center adopts a chain conveyor method during the actual conveyance of workpieces. When conveying workpieces that are heavy and large in volume, due to the lack of corresponding effective support in the middle part of the chain conveyor, the stability of the heavier workpiece during conveyance is poor. Moreover, after the large-volume workpiece is conveyed and machined, the cleaning of the waste chips between the four baffles is rather cumbersome.

[0004] Therefore, we propose a workpiece transmission mechanism for a five-axis gantry machining center to solve the above existing problems. Summary of the Utility Model

The end of the connecting shaft 206 is fixedly provided with a connecting gear 207 that meshes with the two adjacent transmission gears 205. The side of the power box 204 is fixedly provided with a driving motor 208.

[0033] The outer surfaces of several conveying rollers 203 are all covered with anti-skid sleeves 209, and the material of the anti-skid sleeves 209 is elastic rubber, which can prevent slipping between the contact parts of the conveying rollers 203 and the workpiece under the action of the anti-skid sleeves 209, and can effectively protect the surface of the workpiece.

[0034] The output end of the driving motor 208 extends to the interior of the power box 204 and is fixedly connected to the end of a rotating shaft 202 , so that the driving motor 208 can drive the plurality of conveying rollers 203 to rotate synchronously in the same direction.

[0036] Embodiment 2

[0037] On the basis of the first embodiment, and different from the first embodiment,

[0038] A workpiece transmission mechanism for a five-axis gantry machining center, further comprising:

The dust suction cylinder 301 has an open top structure, which is convenient for collecting waste chips.

[0041] Two symmetric collection boxes 302 are fixedly provided on the lower surface of the processing base 100, and a dust suction fan 303 extending into the interior of the collection box 302 is embedded in the lower surface of the collection box 302, which is convenient for automatically introducing waste chips into the collection box 302.

[0042] An inverted Y-shaped dust suction pipe 304 extending into the interiors of the two collection boxes 302 is embedded in the inner bottom wall of the dust suction cylinder 301, and a dust collection bag 305 is fixedly connected by a wire at the end of the inverted Y-shaped dust suction pipe 304 located inside the collection box 302, which is convenient for centrally collecting waste chips through the dust collection bag 305.
