Description

Technical Field

[0001] This application relates to the field of workpiece processing, and more specifically, to a processing platform. Background Technology

[0002] Welding technology, as one of the important processes in industrial production, is widely used in automobile manufacturing, shipbuilding, and machining. Traditional welding operations are usually performed by workers holding welding torches on welding platforms at a fixed height. These platforms are generally designed with a rigid structure and a fixed, non-adjustable height. As the manufacturing industry's requirements for welding quality continue to increase, welding processes are placing more precise demands on the posture and angles of operators.

[0003] In actual production, due to individual differences in operator height, existing fixed-height welding platforms often cannot accommodate operators of different heights, forcing them to maintain unnatural postures during prolonged work. This not only affects welding quality and efficiency but may also harm the operator's health, such as causing occupational diseases like cervical spondylosis and lumbar spondylosis. Furthermore, certain special welding positions require adjusting the workpiece angle to achieve optimal welding results, but existing platforms lack flexible angle adjustment capabilities, making it difficult for operators to obtain ideal welding positions. Utility Model Content

[0004] The purpose of this application is to provide a processing platform that can adjust the welding posture and welding angle to improve welding quality.

[0005] This utility model provides a processing platform, which includes a lifting platform, a support platform, and a rotary drive device. The support platform rotates relative to the lifting platform around a rotation axis. The rotary drive device includes a mounting component, a knob, a crank-slider mechanism, and a transmission component. The mounting component is fixedly connected to the lifting platform. The knob is mounted on the mounting component. One end of the crank-slider mechanism is connected to the knob, and the other end of the crank-slider mechanism is connected to the transmission component. The transmission component is fixedly connected to the support platform. Rotating the knob causes the crank-slider mechanism to drive the transmission component to move along a first direction, which is perpendicular to the axis of the rotation axis.

[0006] In an optional embodiment, the crank-slider mechanism includes a crank, a connecting rod, and a slider. The crank is fixedly connected to the knob. One end of the connecting rod is hinged to the crank, and the other end of the connecting rod is hinged to the transmission component. The slider is disposed at the hinge position between the connecting rod and the transmission component. The mounting component is provided with a sliding groove for the slider to slide along a first direction.

[0007] In an optional embodiment, the mounting component is provided with a scale, the scale is arranged along the first direction, and the slider cooperates with the scale for marking.

[0008] In an optional embodiment, the support frame includes a support frame, a bearing platform, and a rotation locking mechanism. The support frame rotates relative to the lifting platform about the rotation axis, and the bearing platform rotates relative to the support frame about the rotation axis. The rotation axis is set at an angle to the rotation axis. When the rotation is in place, the rotation locking mechanism locks the support frame and the bearing platform.

[0009] In an optional embodiment, the rotation locking mechanism includes a locking member, a first fastener, and a second fastener. The first fastener passes through the locking member and is screwed to the support frame. The second fastener passes through the locking member and is screwed to the bearing platform. The locking member is provided with at least one locking groove, which allows the first fastener and / or the second fastener to slide along a second direction, which is perpendicular to the axial direction of the rotation shaft.

[0010] In an optional embodiment, the number of locking grooves is one, the first fastener passes through the locking groove and slides relative to the locking groove, and when it slides into place, the first fastener is tightened to fix the support frame and the bearing platform.

[0011] In an optional embodiment, the number of locking grooves is one, and both the first fastener and the second fastener pass through the locking groove.

[0012] In an optional embodiment, there are two locking slots, one for the first fastener to pass through and the other for the second fastener to pass through.

[0013] In an optional embodiment, the lifting platform includes multiple sets of lifting leg assemblies, each set of lifting leg assemblies including a support member, a lifting member, and a fixing member, wherein the lifting member is slidably connected to the support member, and the fixing member passes through the lifting member and the support member.

The mounting frame is fixedly connected to the lifting component and rotatably connected to the support platform. The drive end of the lifting drive component is fixedly connected to the mounting component.

[0029] Example 1

[0030] This embodiment applies to workpiece processing, which includes, but is not limited to, welding, assembly, and grinding processes. Welding is used as an example for illustration.

[0031] Please see Figure 1 This embodiment provides a processing platform, which includes a lifting platform 100, a support platform 200, and a rotary drive device 300.

[0032] The lifting platform 100 includes multiple sets of lifting leg assemblies 110. Each set of lifting leg assemblies 110 includes a support member 111, a lifting member 112, and a fixing member 113. The lifting member 112 is slidably connected to the support member 111, and the fixing member 113 passes through the lifting member 112 and the support member 111.

[0033] In this embodiment, the support member 111 is located below the lifting member 112, and both the support member 111 and the lifting member 112 are circular tubes. The diameter of the support member 111 is smaller than the diameter of the lifting member 112. The support member 111 is provided with several through holes, which are spaced apart along the axial direction of the support member 111. The lifting member 112 is provided with several connecting holes, which are spaced apart along the axial direction of the lifting member 112. The lifting member 112 is then fitted onto the support member 111.

[0034] Adjust the height of the lifting leg assembly 110 according to the height of the operator. After the adjustment is completed, connect one connecting hole and one through hole, insert the fixing piece 113, thereby fixing the support piece 111 and the lifting piece 112 and maintaining the height of the lifting leg assembly 110.

[0035] A fixed position is defined by connecting a connecting hole and a through hole, and the number of fasteners 113 is at least one, with the fasteners 113 matching the fixed position.

[0036] Of course, the lifting function of the lifting platform 100 can also be achieved by a hydraulic cylinder or a pneumatic cylinder. The support member 111 of this embodiment can be replaced by the body of the hydraulic cylinder or the pneumatic cylinder, and the lifting member 112 of this embodiment can be replaced by the piston rod of the hydraulic cylinder or the pneumatic cylinder. Therefore, it is not limited to the above-mentioned nested support member 111 and lifting member 112.

[0037] In some embodiments, the height of the lifting leg assembly 110 can be adjusted manually, that is, by manually lifting the lifting member 112, so that the lifting member 112 moves up and down relative to the support member 111 in the vertical direction, that is, the lifting direction is the vertical direction.

[0038] In some embodiments, the height of the lifting leg assembly 110 is adjusted hydraulically or pneumatically. For example, the lifting platform 100 further includes a mounting bracket 120 and a lifting drive component 130. The mounting bracket 120 is fixedly connected to the lifting component 112 and rotatably connected to the support platform 200. The drive end of the lifting drive component 130 is fixedly connected to the mounting component 310. Here, the lifting drive component 130 can be a hydraulic cylinder or a pneumatic cylinder.

[0039] To improve the synchronization of lifting, the lifting platform 100 also includes a connector 140. A connector 140 is provided between two adjacent lifting components 112, thereby connecting multiple lifting components 112 into a whole. When the lifting drive component 130 is activated, the multiple lifting components 112 move up and down as a whole.

[0040] The support frame 200 rotates relative to the lifting frame 100 around the rotation axis a. The axis of rotation a is perpendicular to the lifting direction, that is, the axis of rotation a is horizontal.

[0041] In this embodiment, the rotating shaft a is located on one side of the support frame 200, and the rotating drive device 300 is located on the other side of the support frame 200. By controlling the rotating drive device 300, one side of the support frame 200 is tilted up to achieve the effect of rotation.

[0042] Please see Figures 1 to 3 The rotary drive device 300 includes a mounting component 310, a knob 320, a crank-slider mechanism 330, and a transmission component 340. The mounting component 310 is fixedly connected to the lifting platform 100. The knob 320 is mounted on the mounting component 310. One end of the crank-slider mechanism 330 is connected to the knob 320, and the other end of the crank-slider mechanism 330 is connected to the transmission component 340. The transmission component 340 is fixedly connected to the support platform 200.

[0043] Rotating the knob 320 causes the crank-slider mechanism 330 to drive the transmission component 340 to move along a first direction, which is perpendicular to the axis of rotation a and is vertical.

[0044] Specifically, the crank-slider mechanism 330 includes a crank 331, a connecting rod 332, and a slider 333. The crank 331 is fixedly connected to the knob 320. One end of the connecting rod 332 is hinged to the crank 331, and the other end of the connecting rod 332 is hinged to the transmission member 340. The slider 333 is located at the hinge position between the connecting rod 332 and the transmission member 340. The mounting member 310 is provided with a slide groove 311, which allows the slider 333 to slide along a first direction.

[0045] In some embodiments, the mounting component 310 is provided with a scale 312, which is arranged along a first direction. The slider 333 cooperates with the scale 312 to indicate the scale. Specifically, the scale 312 has multiple scales. For example, 1 to 10, the scale 312 has ten scales, which increase sequentially from bottom to top.

[0046] When slider 333 moves to scale 1, the support platform 200 is in its initial position relative to the lifting platform 100. At this time, the support platform 200 is horizontal. When slider 333 moves upward to scale 2, the support platform 200 rotates relative to the lifting platform 100 by a first angle. At this time, the support platform 200 is tilted. When slider 333 continues to move upward to scale 3, the support platform 200 rotates relative to the lifting platform 100 by a second angle. Obviously, the second angle is greater than the first angle, and so on.

[0047] Based on the above, this embodiment further explains the operating principle of the processing platform as follows:

[0048] S100. Adjust the lifting leg assembly 110 according to the operator's height to adapt to the welding posture.

[0049] Specifically, the lifting drive component 130 is activated, which drives the lifting component 112 to move up and down, thereby adjusting the height of the lifting leg assembly 110 and realizing the height adjustment of the processing platform.

[0050] S200. Control the rotary drive device 300 to drive one side of the support platform 200 to tilt up, so that the support platform 200 rotates relative to the lifting platform 100 to adjust the welding angle.

[0051] Specifically, rotating the knob 320 causes the crank-slider mechanism 330 to move, which in turn causes the transmission plate to move up and down, thereby driving one side of the support frame 200 to tilt up.

[0052] The application also allows for the adjustment of the processing platform height via the lifting platform 100 to match the height of the welding worker, facilitating the adjustment of welding posture and protecting the operator's health. Furthermore, the application enables the adjustment of the workpiece welding angle by rotating the support platform 200 relative to the lifting platform 100, thereby improving welding quality.

[0053] Example 2

[0054] Please see Figure 1 and Figure 4 Based on Embodiment 1, this embodiment is improved in that the support frame 200 includes a support frame 210, a bearing platform 220 and a rotation locking mechanism 230. The support frame 210 rotates relative to the lifting platform 100 around a rotation axis a, and the bearing platform 220 rotates relative to the support frame 210 around a rotation axis b. The rotation axis b is set at an angle to the rotation axis a. When the rotation is in place, the rotation locking mechanism 230 locks the support frame 210 and the bearing platform 220.

[0055] In this embodiment, the rotating shaft b is located in the middle of the support frame 210, and the rotating locking mechanism 230 is located on one side of the support frame 210. The angle between the support frame 210 and the support platform 220 is adjusted manually. After the rotation is in place, the rotating locking mechanism 230 is used to lock and fix the support frame 210 and the support platform 220 to maintain a fixed angle.

[0056] The rotating locking mechanism 230 includes a locking member 231, a first fastener 232 and a second fastener 233. The first fastener 232 passes through the locking member 231 and is screwed to the support frame 210. The second fastener 233 passes through the locking member 231 and is screwed to the bearing platform 220. The locking member 231 is provided with at least one locking groove 2311. The locking groove 2311 allows the first fastener 232 and / or the second fastener 233 to slide along a second direction, which is perpendicular to the axial direction of the rotating shaft b.

[0057] In this embodiment, the second direction can be set to be vertical, and an L-shaped plate 234 can be set below the support frame 210 and the bearing platform 220 respectively, with the L-shaped plate 234 serving as the screw connection position.

[0058] There are several different designs for the locking groove 2311, which will be explained in detail below:

[0059] In some embodiments, there is one locking groove 2311. The first fastener 232 passes through the locking groove 2311 and slides relative to the locking groove 2311. When it slides into place, the first fastener 232 is tightened to fix the support frame 210 and the carrier platform 220.

[0060] In some embodiments, the number of locking grooves 2311 is one, and the first fastener 232 and the second fastener 233 are both inserted into the locking groove 2311.

[0061] In some embodiments, there are two locking grooves 2311, one for the first fastener 232 to pass through and the other for the second fastener 233 to pass through.

[0062] Whether adjusting the position of the first fastener 232, the second fastener 233, or both, the essence is to adjust the included angle between the support frame 210 and the bearing platform 220.

[0063] In this embodiment, the rotation axis b and the rotation axis a can be set at a right angle, that is, the axis of the rotation axis b is perpendicular to the axis of the rotation axis a. If the rotation of the rotation axis a is defined as the left and right rotation of the support platform 220, then the rotation of the rotation axis b is the forward and backward rotation of the support platform 220, and the two rotations are angle adjustments with different degrees of freedom.

[0064] This embodiment is based on the one degree of freedom rotation angle adjustment in Embodiment 1. This embodiment adds one degree of freedom rotation angle adjustment, that is, this embodiment has two degrees of freedom rotation angle adjustment, which is more flexible and conducive to improving welding quality and reducing product defect rate.
