Description

Technical Field

[0001] This utility model belongs to the field of welding robot technology, and in particular relates to a scissor arm lifting and moving platform suitable for welding robots. Background Technology

[0002] Currently, in certain specific welding operations, it is often necessary to use a lifting and moving platform to elevate and feed the welding robot forward and backward to adapt to different welding situations. This lifting and moving platform typically uses a hydraulically driven scissor arm structure for lifting and lowering. However, this type of lifting and moving platform is susceptible to lateral forces during the lifting and lowering process, which can easily cause the platform to sway. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this invention provides a scissor arm lifting and moving platform suitable for welding robots, which can improve the stability of the lifting process.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A scissor-arm lifting mobile platform suitable for welding robots, comprising:

[0006] The base has two longitudinally extending first linear guide rails fixedly connected to its upper end. A first support, a second support, and a first rotary drive mechanism are sequentially fixedly connected to the upper end of the base along the longitudinal direction. A longitudinally extending lead screw is rotatably connected to the first and second supports. One end of the lead screw passes through the second support and is fixedly connected to the output end of the first rotary drive mechanism. A lead screw nut is threaded onto the lead screw. Two first sliders are respectively slidably connected to the two first linear guide rails on both sides of the lead screw nut. The longitudinal direction is the forward and backward feed direction.

[0007] The platform has two longitudinally extending second linear guide rails fixedly connected to its lower end, and two second sliders are slidably connected to the two second linear guide rails respectively.

[0008] Two scissor lifts, both of the same specifications, with the lower rear side of each scissor lift hinged to the upper end of the base, the lower front side of each scissor lift hinged to both sides of the lead screw nut, the upper rear side of each scissor lift hinged to the lower end of the platform, and the upper front side of each scissor lift hinged to the two second sliders.

[0009] The front and rear feed mechanism is set on the platform, and the output end of the front and rear feed mechanism is fixedly connected to the welding robot.

[0010] The beneficial effects of adopting the above technical solution are as follows: the two pairs of cooperating first linear guides and first sliders can provide stable support for the sliding of the lead screw nut, which is conducive to providing stable support for the sliding of the lower front side of the two scissor lifts. At the same time, the two pairs of cooperating second linear guides and second sliders can respectively enable the upper front side of the two scissor lifts to slide stably. Therefore, when the lead screw is driven by the first rotation drive mechanism, the lead screw nut on it can drive the lower front side of the two scissor lifts to slide stably, and the upper end of the two scissor lifts to slide stably, thereby enabling the platform and the welding robot on it to rise and fall stably. In addition, the forward and backward feed mechanism can realize the forward and backward feed of the welding robot.

[0011] Furthermore, the forward and backward feeding mechanism includes a mounting plate for the welding robot fixedly connected to the upper end, two longitudinally extending third linear guides and a longitudinally extending rack fixedly connected to the upper end of the platform, a second rotation drive mechanism fixedly connected to the lower end of the platform, a gear meshing with the rack fixedly connected to the output end of the second rotation drive mechanism, and two third sliders respectively slidably connected to the two third linear guides on both sides of the lower end of the mounting plate.

[0012] The beneficial effects of adopting the above technical solution are as follows: the gear is driven by the second rotation drive mechanism, which can make the rack move longitudinally relative to the mounting plate, thereby making the mounting plate move longitudinally relative to the platform, thus realizing the forward and backward feeding of the welding robot; in addition, the two pairs of mutually cooperating third linear guides and third sliders can provide stable support for the sliding of the mounting plate, which is conducive to the stable forward and backward feeding of the mounting plate and the welding robot on it.

[0013] Furthermore, a welding robot is fixedly connected to the middle of the mounting plate.

[0014] The beneficial effects of adopting the above technical solution are: this setting is conducive to the uniform transmission of force to both sides and to improving the stability of the front and rear feed mechanisms.

[0015] Furthermore, a second rotation drive mechanism is fixedly connected to the middle of the mounting plate.

[0016] The beneficial effect of adopting the above technical solution is that this setting facilitates the uniform transmission of force to both sides.

[0017] Furthermore, the second rotation drive mechanism is a geared motor.

[0018] Furthermore, a coupling is provided between the first rotation drive mechanism and the lead screw.

[0019] Furthermore, the first rotation drive mechanism is a geared motor.

[0020] Furthermore, the scissor lift is X-shaped.

[0021] Furthermore, the scissor lift includes a first link and a second link arranged in a cross configuration, with the middle portion of the first link hinged to the middle portion of the second link.

[0022] Furthermore, the output end of the welding robot is detachably connected to a welding torch.

[0023] The beneficial effects of this utility model are as follows:

[0024] Two pairs of cooperating first linear guides and first sliders provide stable support for the sliding of the lead screw nut, which in turn provides stable support for the sliding of the lower front side of the two scissor lifts. At the same time, two pairs of cooperating second linear guides and second sliders can respectively enable the upper front side of the two scissor lifts to slide stably. Therefore, when the lead screw is driven by the first rotation drive mechanism, the lead screw nut on it can drive the lower front side of the two scissor lifts to slide stably, and the upper end of the two scissor lifts to slide stably, thereby enabling the platform and the welding robot on it to rise and fall stably.

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] This utility model provides a scissor arm lifting and moving platform suitable for welding robots, such as... Figure 1 and Figure 2 As shown, it includes:

[0034] The base 1 has two longitudinally extending first linear guide rails 4 fixedly connected to its upper end. The upper end of the base 1 is also fixedly connected to a first support 15, a second support 6, and a first rotation drive mechanism 7 in sequence along the longitudinal direction. A longitudinally extending lead screw 5 is rotatably connected to the first support 15 and the second support 6. One end of the lead screw 5 passes through the second support 6 and is fixedly connected to the output end of the first rotation drive mechanism 7. A lead screw nut 16 is threaded onto the lead screw 5. Two first sliders 2 are respectively slidably connected to the two first linear guide rails 4 on both sides of the lead screw nut 16. The longitudinal direction is the forward and backward feed direction.

[0035] Platform 8, with two longitudinally extending second linear guide rails 17 fixedly connected to the lower end of platform 8, and two second sliders 18 slidably connected to the two second linear guide rails 17 respectively;

[0036] Two scissor lifts 3, both scissor lifts 3 are of the same specification, the lower rear side of both scissor lifts 3 is pivotally connected to the upper end of the base 1, the lower front side of both scissor lifts 3 is pivotally connected to both sides of the lead screw nut 16, the upper rear side of both scissor lifts 3 is pivotally connected to the lower end of the platform 8, and the upper front side of both scissor lifts 3 is pivotally connected to the two second sliders 18.

[0037] The front and rear feed mechanism is set on the platform 8, and the output end of the front and rear feed mechanism is fixedly connected to the welding robot 10.

[0038] It is understandable that the two pairs of cooperating first linear guides 4 and first sliders 2 can provide stable support for the sliding of the lead screw nut 16, which is beneficial for providing stable support for the sliding of the lower front side of the two scissor lifts 3. At the same time, the two pairs of cooperating second linear guides 17 and second sliders 18 can respectively enable the upper front side of the two scissor lifts 3 to slide stably. Therefore, when the lead screw 5 is driven by the first rotation drive mechanism 7, the lead screw nut 16 on it can drive the lower front side of the two scissor lifts 3 to slide stably, and the upper side of the two scissor lifts 3 to slide stably, thereby enabling the platform 8 and the welding robot 10 on it to rise and fall stably, which is beneficial for heavy-duty scenarios. In addition, the forward and backward feed mechanism can realize the forward and backward feed of the welding robot 10.

[0039] It should be noted that bearings can be installed between the lead screw 5 and the first support 15 and the second support 6.

[0040] In one embodiment, the forward and backward feeding mechanism includes a mounting plate 12 with the welding robot 10 fixedly connected to its upper end, two longitudinally extending third linear guide rails 13 and a longitudinally extending rack 9 fixedly connected to the upper end of the platform 8, a second rotation drive mechanism fixedly connected to the lower end of the platform 8, a gear meshing with the rack 9 fixedly connected to the output end of the second rotation drive mechanism, and two third sliders 14 that are slidably connected to the two third linear guide rails 13 respectively fixedly connected to the lower ends of the mounting plate 12.

[0041] Understandably, the gear, driven by the second rotation drive mechanism, can cause the rack 9 to move longitudinally relative to the mounting plate 12, which in turn causes the mounting plate 12 to move longitudinally relative to the platform 8, thereby realizing the forward and backward feeding of the welding robot 10. In addition, the two pairs of cooperating third linear guides 13 and third sliders 14 can provide stable support for the sliding of the mounting plate 12, which is conducive to the stable forward and backward feeding of the mounting plate 12 and the welding robot 10 on it, and thus is more suitable for heavy-duty scenarios.

[0042] In one embodiment, the welding robot 10 is fixedly connected to the upper middle part of the mounting plate 12, which facilitates the uniform transmission of force to both sides and improves the stability of the front and rear feeding mechanism.

[0043] In one embodiment, a second rotation drive mechanism is fixedly connected to the lower center of the mounting plate 12 to facilitate the uniform transmission of force to both sides.

[0044] In one embodiment, both the first rotation drive mechanism 7 and the second rotation drive mechanism are geared motors.

[0045] In one embodiment, a coupling is provided between the first rotary drive mechanism 7 and the lead screw 5.

[0046] In one embodiment, the scissor lift 3 is "X" shaped and includes a first link and a second link that are arranged in a cross configuration, with the middle portion of the first link pivotally connected to the middle portion of the second link.

[0047] In one embodiment, the output end of the welding robot 10 is detachably connected to a welding torch 11 to facilitate the installation of the welding torch 11 onto the welding robot 10 or the removal of the welding torch 11 from the welding robot 10.

[0048] In summary, this invention enables rapid lifting and feeding, allowing the welding robot 10 to be accurately and unimpededly delivered to any designated position for welding operations. Furthermore, this invention is easy to operate, saves manpower, and reduces costs while increasing efficiency. Additionally, this invention is also suitable for heavy-duty scenarios.
