Description

Technical Field

[0001] This invention belongs to the field of robotic arm technology, specifically relating to a multi-station machine tool robotic arm for processing aluminum alloy workpieces. Background Technology

[0002] In existing technologies, multi-station machine tool robots for machining aluminum alloy workpieces are widely used in automated machining systems to achieve automatic transfer and positioning of workpieces between different stations. However, traditional robots have the following prominent problems in the handling process: Workpieces are prone to swaying during handling: especially during high-speed or large-span movement, due to insufficient rigidity of the mechanical structure or lack of effective anti-sway measures, workpieces are prone to swinging, which leads to a decrease in positioning accuracy, or even collisions or falling off, affecting processing quality and equipment safety.

[0003] Positioning accuracy is difficult to guarantee: Most robotic arms use direct motor drive or gear transmission for station switching, which has problems such as inaccurate switching angle and large cumulative error. It is difficult to achieve high repeatability of fixed-point switching, especially in application scenarios with high requirements for multi-station machine tools.

[0004] The clamping mechanism is slow to respond and has poor adaptability: Traditional pneumatic or electric clamping mechanisms are not fast enough in the clamping and releasing process, and have poor adaptability to workpieces of different shapes and sizes, lacking fast, stable and flexible clamping capabilities.

[0005] Complex structure and difficult maintenance: Some robotic arms use multiple motors and multiple sensors for collaborative control. Although they are powerful, they are complex in structure, have high manufacturing costs, high failure rates, and are difficult to maintain and debug.

[0006] Therefore, there is an urgent need for a multi-station machine tool robot for machining aluminum alloy workpieces that has high anti-sway performance, high positioning accuracy, fast response clamping capability, reasonable structure, and easy maintenance, so as to improve the overall performance and reliability of machine tool automation systems.

At the same time, the anti-sway ball head and the anti-sway ball table of the present invention are in a vertical rotation structure on the same horizontal plane. Through the natural pull of gravity on the anti-sway mounting plate and the above-mentioned vertical rotation structure, the anti-sway mounting plate always remains in a vertical state, which has the function of preventing swaying and realizing the prevention of swaying of the machine tool workpiece during the repositioning process.

A clamping end arm 408 is fixedly installed at the bottom of the clamping folding arm 410. A rubber pad 407 is installed on the inner wall of the clamping end arm 408. Auxiliary hinge arms 409 are rotatably installed at both ends of the corner arm of the clamping folding arm 410.

[0038] In this embodiment, the clamping arm mounting plate 401 is fixed to the anti-sway mounting plate 308 by mounting bolts 309 and nuts.

[0039] In this embodiment, the top of the folding arm end plate 411 is rotatably mounted on the clamping arm main platform 403.

[0040] In this embodiment, the end of the auxiliary hinge arm 409 away from the clamping folding arm 410 is rotatably mounted on the end lug 405.

[0041] In this embodiment, the lowering of the tensioning arm 406 is driven by the third hydraulic cylinder 404, and multiple auxiliary articulated arms 409 simultaneously push outward on multiple clamping end arms 408 at the bottom of the clamping arm 410.

[0042] In this embodiment, the third hydraulic cylinder 404 drives the tensioning arm 406 to rise, and multiple auxiliary articulated arms 409 simultaneously form a structure that pulls multiple clamping end arms 408 at the bottom of the clamping folding arm 410 inward.

[0043] The working principle of this invention is as follows: Existing machine tool robots lack necessary anti-sway functions when performing multi-station repositioning, which can lead to the workpiece not being properly aligned with the station after it arrives at its position. Furthermore, for some precision components, repositioning sway can cause internal damage. To overcome these problems, this invention provides a machine tool workpiece anti-sway arm assembly 300 below the workpiece displacement arm assembly 200 to prevent workpiece swaying during transport. Below the anti-sway arm assembly 300 is a machine tool workpiece clamping arm assembly 400 for clamping the workpiece. Specifically, the clamping arm mounting plate 401 is fixed to the anti-sway mounting plate 308 by mounting bolts 309 and nuts. The top of the folding arm end plate 411 is rotatably mounted on the clamping arm main table 403. An auxiliary hinged arm 40... One end of the clamping arm 410, away from the clamping arm 410, is rotatably mounted on the end ear 405. A third hydraulic cylinder 404 drives the lowering of the tensioning arm 406, causing multiple auxiliary hinge arms 409 to simultaneously push outwards against the multiple clamping end arms 408 at the bottom of the clamping arm 410. Conversely, a third hydraulic cylinder 404 drives the uppering of the tensioning arm 406, causing the multiple auxiliary hinge arms 409 to simultaneously pull inwards against the multiple clamping end arms 408 at the bottom of the clamping arm 410. In actual use, when the third hydraulic cylinder 404 rises, the auxiliary hinge arms 409 simultaneously pull the clamping arm 410 inwards, creating a clamping structure for the machine tool workpiece at the bottom of the multiple clamping arms 410. This method effectively... The present invention enables rapid fixation of workpieces during machine tool workpiece repositioning. Simultaneously, when the workpiece is in position, as the third hydraulic cylinder 404 descends, multiple auxiliary hinged arms 409 synchronously push outwards against multiple clamping end arms 408 at the bottom of the clamping arm 410. This method achieves rapid release of the workpiece from clamping. Meanwhile, the top of the anti-sway arm 302 is fixed to the bottom of the first hydraulic cylinder 205. When the anti-sway ball table 304 rotates within the square anti-sway arm 301, the anti-sway ball head 310 is rotatably positioned within the anti-sway ball table 304. At this time, the first anti-sway shaft 303 and the second anti-sway shaft 306 are on the same horizontal plane, and the first anti-sway shaft 303 and the second anti-sway shaft 306 form a 90-degree vertical structure. The anti-sway installation at the bottom of the anti-sway ball head 310... The anti-sway mounting plate 308 is equipped with a machine tool workpiece clamping arm assembly 400, which clamps the machine tool workpiece onto the anti-sway mounting plate 308. In actual use, the weight of the workpiece on the anti-sway mounting plate 308 and the machine tool workpiece clamping arm assembly 400 will exert a natural gravitational pull on the anti-sway ball head 310. Simultaneously, because the second anti-sway shaft 306 is rotatably mounted within the anti-sway ball table 304, and the anti-sway ball table 304 is rotatably mounted within the square anti-sway arm 301, and the anti-sway ball head 310 and the anti-sway ball table 304 are on the same horizontal plane and in a vertical rotation structure, the natural gravitational pull on the anti-sway mounting plate 308 and the aforementioned vertical rotation structure ensure that the anti-sway mounting plate 308 is always in a vertically downward anti-sway structure. In this way...To prevent workpiece from shaking during machine tool repositioning.

[0044] Based on the above, in order to facilitate the control of the movement of the machine tool workpiece in the longitudinal and transverse directions, the bottom of the shifting machine base spindle 110 of the present invention is fixedly mounted on the displacement end arm 201. The moving end arm 207 slides linearly in the displacement transverse groove 202, and the guide side block 208 slides in the displacement side groove 209. The top of the anti-sway arm 302 is fixed to the bottom of the first hydraulic cylinder 205. The movement of the machine tool workpiece in the transverse direction is achieved by pushing the moving end arm 207 through the second hydraulic cylinder 210. The movement of the machine tool workpiece in the longitudinal direction is achieved by pushing the anti-sway arm assembly 300 of the machine tool workpiece through the first hydraulic cylinder 205. In order to ensure the stability of the transverse displacement, the displacement transverse arm 203 of the present invention has a displacement transverse groove 202 inside, and displacement side grooves 209 are opened at both ends of the displacement transverse arm 203. Guide side blocks 208 are fixedly mounted at both ends of the moving end arm 207. The guide side blocks 208 slide in the displacement side groove 209. In this way, the stability of the transverse displacement is achieved.

[0045] Based on the above, in order to solve the problem of fixed-point repositioning when changing positions between multiple workstations, the machine tool workpiece of the present invention is repositioned at a fixed point between multiple workstations of the machine tool through a multi-workstation repositioning base assembly 100. Specifically, a base drive wheel 104 is fixedly installed on the top of the repositioning base spindle 110. The base drive wheel 104 is provided with multiple drive wheel shifting grooves 103 and drive wheel limiting grooves 105. A drive motor 109 is fixedly installed at the end of the repositioning base arm plate 111 away from the L-shaped arm 113. A notched repositioning wheel 106 is provided on the output shaft of the drive motor 109. A repositioning wheel support arm 108 is fixedly installed at the bottom of the notched repositioning wheel 106. A repositioning wheel support rod 107 is fixedly installed at the end of the repositioning wheel support arm 108 away from the notched repositioning wheel 106. Multiple drive wheel shifting grooves 103 and drive wheel limiting grooves 105 are provided. The moving wheel limiting groove 105 is spaced out on the machine base drive wheel 104. In actual use, the notched shifting wheel 106 is driven to rotate by the drive motor 109. At this time, the notched shifting wheel 106 drives the shifting wheel support rod 107 on the shifting wheel support arm 108 to rotate. When the shifting wheel support rod 107 on the shifting wheel support arm 108 drives the machine base drive wheel 104 to rotate through the drive wheel actuation groove 103, the machine base drive wheel 104 will rotate at a fixed angle because the drive of the shifting wheel support rod 107 to the machine base drive wheel 104 through the drive wheel actuation groove 103 is at a fixed angle. At this time, the workpiece on the machine tool workpiece clamping arm assembly 400 realizes fixed-point shifting between multiple stations. In this way, the rapid and accurate rotation and shifting movement of the workpiece between multiple stations is guaranteed each time it is shifted.
