DETAILED DESCRIPTION

[0019] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. The specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0021] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0022] The present application provides a description of an adjustable tilting and tilting tipping trolley.

[0023] like Figures 1 to 3 As shown, one embodiment of this application provides an adjustable tilting and tilting loading trolley, including a trolley body 1, a lifting frame 2, a mounting frame 3, an upper guide rail shaft 4, an eccentric wheel 5, and an adjustment and positioning assembly 6.

[0024] The lifting frame 2 slides and lifts on the vehicle body 1; the mounting frame 3 is set on the lifting frame 2 and is used to rotate and connect the material plate 11; the upper guide rail shaft 4 is horizontally fixed on the lifting frame 2 and passes through the top of the mounting frame 3; the eccentric wheel 5 is rotatably set at the bottom of the mounting frame 3, and the outer circumference of the eccentric wheel 5 abuts against the lifting frame 2.

[0025] The adjusting positioning component 6 is set on the lifting frame 2 and connected to the eccentric wheel 5. The adjusting positioning component 6 is used to drive the eccentric wheel 5 to rotate and then fix it. When the adjusting positioning component 6 drives the eccentric wheel 5 to rotate, the eccentric end of the eccentric wheel 5 gradually approaches the lifting frame 2, so that the bottom of the mounting frame 3 gradually moves away from the lifting frame 2.

[0026] Specifically, in this embodiment, the eccentric end of the eccentric wheel 5 is the end of the outer circumference of the eccentric wheel 5 that is furthest from its own axis. The lifting frame 2 can be raised and lowered by a cylinder or linear module on the vehicle body 1; the material plate 11 can be rotated by a worm gear mechanism on the vehicle body 1, wherein the worm gear is mounted on the mounting frame 3 and is coaxially fixed with the rotating shaft of the material plate 11, the worm is mounted on the mounting frame 3 and meshes with the worm gear, and a handwheel is provided at the outer end of the worm, so that the material plate 11 can be flipped by rotating the handwheel.

[0027] This embodiment provides an adjustable tilting and tilting loading trolley. Compared with the prior art, it uses the upper guide rail shaft 4 as the rotation shaft of the top of the mounting frame 3. When the material plate 11 bends downward, the positioning component 6 is adjusted to drive the eccentric wheel 5 at the bottom of the mounting frame 3 to rotate, so that the eccentric end of the eccentric wheel 5 gradually approaches the lifting frame 2, and the bottom of the mounting frame 3 gradually moves away from the lifting frame 2. The tilt angle of the material plate 11 can be adjusted according to actual needs. When the material plate 11 bends downward, the rotation of the eccentric wheel 5 is adjusted to move the bottom of the mounting frame 3 away from the lifting frame 2, so that the material plate 11 returns to a suitable angle, ensuring the smooth progress of the loading operation.

[0028] In the feeding operation of the multi-wire cutting machine, the feeding card slot can be more accurately aligned, the feeding precision and efficiency are improved, the risk of feeding failure and equipment damage caused by the bending of the material plate 11 is reduced, and a strong guarantee is provided for the smooth progress of the production process.

[0029] As shown in Figures 4 to 5 The specific implementation of the application based on the above embodiments is as follows: The adjusting and positioning assembly 6 comprises an adjusting rod 61 and a positioning rod 62; the adjusting rod 61 is rotationally arranged at the bottom of the mounting frame 3 and coaxially fixed with the eccentric wheel 5; a plurality of inclined teeth 611 are arranged at the top surface of the adjusting rod 61, and the inclined ends of the inclined teeth 611 are directed towards the eccentric wheel 5. The positioning rod 62 is rotationally connected to the lifting frame 2, and the bottom end of the positioning rod 62 is engaged between adjacent inclined teeth 611.

[0030] Specifically, when the eccentric wheel 5 is in the initial state, the mounting frame 3 is in the vertical state. After the eccentric wheel 5 is rotated, the top of the bottom end of the positioning rod 62 is clamped by the gravity of the mounting frame 3, so as to keep the position of the mounting frame 3 fixed.

[0031] When the adjusting rod 61 rotates, the eccentric wheel 5 can be driven to rotate synchronously, and the rotation angle of the eccentric wheel 5 can be accurately controlled through the arrangement of the plurality of inclined teeth 611. When the adjusting rod 61 rotates, the positioning rod 62 can cooperate with the inclined teeth 611 to achieve positioning and fixing. After the eccentric wheel 5 is adjusted to rotate to the appropriate position, the positioning rod 62 can prevent the adjusting rod 61 from rotating in the reverse direction, so as to ensure the stability of the position of the eccentric wheel 5, and effectively avoid the position change of the eccentric wheel 5 caused by vibration or external force.

[0032] In actual operation, the operator can easily adjust the rotation angle of the eccentric wheel 5 by rotating the adjusting rod 61, and then adjust the pitch angle of the material plate 11, thereby improving the precision and stability of the feeding operation, reducing the operation difficulty of the operator, and improving the work efficiency.

[0033] As shown in Figures 4 to 5 The specific implementation of the application based on the above embodiments is as follows: The adjusting and positioning assembly 6 further comprises a first tension spring 63, one end of the first tension spring 63 is connected to the lifting frame 2, and the other end is connected to the adjusting rod 61; the first tension spring 63 is always in a stretched state to make the bottom end of the positioning rod 62 abut against the inclined teeth 611.

[0034] The first tension spring 63 can pull the adjusting rod 61 towards the positioning rod 62, and the positioning rod 62 is always closely engaged with the inclined teeth 611, thereby reducing the influence of the adjusting and positioning assembly 6 under various vibrations and external forces, and improving the position stability of the eccentric wheel 5.

[0035] Further, when adjusting the rotation of the eccentric wheel 5, the tension of the first tension spring 63 can help the adjusting rod 61 to keep stable rotation, reducing the shaking and jamming phenomenon in the adjusting process. At the same time, after the adjustment is completed, the tension of the first tension spring 63 can quickly pull the positioning rod 62 to a state of close meshing with the helical tooth 611, realizing rapid positioning.

[0036] As shown in Figures 4 to 5 , the application provides a specific implementation manner based on the above-mentioned implementation manner as follows: The adjusting and positioning assembly 6 further comprises a second tension spring 64, one end of the second tension spring 64 being connected to the adjusting rod 61, and the other end being connected to the positioning rod 62; the second tension spring 64 is always in a stretched state, so that the bottom end of the positioning rod 62 is abutted against the top surface of the adjusting rod 61.

[0037] The extension and retraction directions of the first tension spring 63 and the second tension spring 64 are opposite, and the tension of the first tension spring 63 is greater than that of the second tension spring 64.

[0038] The second tension spring 64 can pull the positioning rod 62 towards the top surface of the adjusting rod 61, so that the bottom end of the positioning rod 62 is abutted against the top surface of the adjusting rod 61 between the adjacent helical teeth 611, further enhancing the connection stability between the positioning rod 62 and the adjusting rod 61.

[0039] In actual work, the design of the double tension springs can effectively prevent the positioning rod 62 from deviating due to external force or vibration during the adjusting process. When the eccentric wheel 5 is adjusted to the appropriate position, the first tension spring 63 and the second tension spring 64 jointly act, so that the positioning rod 62 is firmly abutted against the helical tooth 611 and the top surface of the adjusting rod 61, improving the anti-interference ability of the adjusting and positioning assembly 6.

[0040] As shown in Figure 5 , the application provides a specific implementation manner based on the above-mentioned implementation manner as follows: The top surface of the adjusting rod 61 is threadedly connected with a positioning bolt 612, and the positioning bolt 612 is located on the side of the helical tooth 611 away from the eccentric wheel 5; when the eccentric wheel 5 is in the initial state, the bottom end of the positioning rod 62 is abutted against the side of the positioning bolt 612 close to the helical tooth 611.

[0041] When the material plate 11 does not appear to bend downward, the positioning bolt 612 can limit the bottom end of the positioning rod 62, and the bottom end of the positioning rod 62 is kept abutted against the positioning bolt 612 under the influence of the first tension spring 63, which can avoid damaging the helical tooth 611, the positioning bolt 612 is more convenient to replace and maintain than the helical tooth 611, and the service life of the adjusting rod 61 is improved.

[0042] As shown in Figure 4 , Figure 6And Figure 7 Based on the above-mentioned embodiments, the present application further provides a specific embodiment as follows: The lifting frame 2 is provided with a left-right fine adjustment assembly 7, which comprises a screw rod 71, a rotating nut 72, a push piece 73 and an anti-rotation rod 74. The screw rod 71 is rotationally connected to the lifting frame 2 and is parallel to the upper rail shaft 4; the rotating nut 72 is threadedly connected to the screw rod 71 (the thread line of the screw rod 71 is not shown in the figure), and a limiting ring groove 721 is coaxially formed in the middle position of the outer circumferential surface of the rotating nut 72.

[0043] The push piece 73 is fixed to the mounting frame 3 and extends into the limiting ring groove 721 at one end, and a limiting clamping groove 731 is formed in the inner side surface of the push piece 73 facing the upper rail shaft 4; the anti-rotation rod 74 is fixed in the limiting ring groove 721 and is always located in the limiting clamping groove 731.

[0044] Reference Figure 6 And Figure 8 The end of the push rod with the limiting clamping groove 731 is always located in the limiting ring groove 721.

[0045] Specifically, the outer end of the screw rod 71 is provided with a hand wheel in this embodiment, so as to facilitate the rotation of the screw rod 71. In this embodiment, the anti-rotation rod 74 can be a bolt, which is screwed onto the rotating nut 72 and has its inner end inserted into the limiting clamping groove 731, thereby achieving the anti-rotation effect between the rotating nut 72 and the push piece 73, which is convenient to operate and maintain.

[0046] When feeding the multi-wire cutting machine, the feeding trolley is pushed to align the material plate 11 with the loading clamping groove as much as possible. At this time, the left-right position of the mounting frame 3 and the material plate 11 can be accurately adjusted through the left-right fine adjustment assembly 7, so as to improve the feeding accuracy and efficiency.

[0047] When adjusting the left-right position of the mounting frame 3 and the material plate 11, rotating the screw rod 71 can drive the rotating nut 72 to move on the screw rod 71; since one end of the push piece 73 is located in the limiting ring groove 721 of the rotating nut 72, the rotating nut 72 can drive the push piece 73 to translate together; and due to the limiting between the anti-rotation rod 74 on the rotating nut 72 and the limiting clamping groove 731, the rotating nut 72 cannot rotate, thereby achieving the synchronous translation of the rotating nut 72, the push piece 73 and the mounting frame 3, improving the left-right fine adjustment efficiency of the material plate 11 and the mounting frame 3, and further improving the feeding accuracy and efficiency.

[0048] Meanwhile, the upper guide rail shaft 4 serves as a rotating shaft of the mounting frame 3 and a guide rail for the left-right translation of the mounting frame 3. When the pitch angle of the material plate 11 is adjusted, the eccentric wheel 5 drives the rotation of the mounting frame 3, so that the end of the limiting slot 731 of the push piece 73 gradually moves away from the screw rod 71, but the end of the push piece 73 is always located in the limiting ring slot 721, so that the pitch angle of the material plate 11 and the mounting frame 3 can be adjusted first, or the left-right position of the material plate 11 and the mounting frame 3 can be adjusted first, and then the pitch angle of the material plate 11 and the mounting frame 3 is adjusted. The cooperation of the pitch angle adjustment and the left-right position adjustment of the material plate 11 and the mounting frame 3 is realized, and the feeding efficiency and the operation convenience of the feeding trolley are further improved.

[0049] As shown in Figure 4 , the application provides a specific implementation mode based on the above-mentioned implementation mode as follows: The pitch-adjustable and roll-adjustable turnover feeding trolley further comprises a lower guide rail shaft 8, which penetrates the bottom of the mounting frame 3 and is parallel to the upper guide rail shaft 4.

[0050] The eccentric wheel 5 is coaxially fixed on the lower guide rail shaft 8, and the lifting frame 2 is provided with a limiting assembly 9 for limiting the axial position of the eccentric wheel 5.

[0051] Due to the axial limitation of the limiting assembly 9 on the eccentric wheel 5, the position of the eccentric wheel 5 and the lower guide rail shaft 8 is always fixed when the mounting frame 3 is finely adjusted left and right, thereby realizing the additional support and guidance of the lower guide rail shaft 8 on the mounting frame 3.

[0052] Meanwhile, the lower guide rail shaft 8 also acts between the eccentric wheel 5 and the mounting frame 3. When the eccentric wheel 5 rotates, the eccentric wheel 5 can directly drive the lower guide rail shaft 8 penetrating the mounting frame 3 to rotate, so that the lower guide rail shaft 8 drives the mounting frame 3 to rotate, thereby improving the stress uniformity and contact area of the mounting frame 3, and further improving the rotation stability of the mounting frame 3 and the material plate 11.

[0053] As shown in Figure 9 , the application provides a specific implementation mode based on the above-mentioned implementation mode as follows: The end of the positioning rod 62 close to the eccentric wheel 5 has a circular ring part 613, and the eccentric wheel 5 and the circular ring part 613 are both keyed to the lower guide rail shaft 8.

[0054] Threaded holes are formed at both ends of the lower guide rail shaft 8, and a baffle 81 and a plugging bolt 82 are arranged at both ends of the lower guide rail shaft 8. The plugging bolt 82 is threadedly connected with the threaded hole after penetrating the baffle 81.

[0055] The key connection mode enables synchronous rotation between the positioning rod 62, the eccentric wheel 5 and the lower guide rail shaft 8, ensuring the action consistency and accuracy of the adjustment positioning assembly 6. The setting of the blocking piece 81 and the blocking bolt 82 plays a fixing and limiting role, improving the stability of the eccentric wheel 5 and the positioning rod 62, and the disassembly and maintenance efficiency of the eccentric wheel 5 and the positioning rod 62.

[0056] As shown in Figure 4 and Figure 9 , the application provides a specific embodiment based on the above embodiments as follows: The limiting assembly 9 includes a limiting plate 91 fixed in the lifting frame 2 and located at one side of the eccentric wheel 5 close to the end of the lower guide rail shaft 8. Among them, the limiting plate 91 is clamped between the limiting plate 91 and the inner end of the key groove on the lower guide rail shaft 8.

[0057] During the rotation of the eccentric wheel 5, the limiting plate 91 can cooperate with the inner end of the key groove on the lower guide rail shaft 8 to limit the axial displacement of the eccentric wheel 5, ensuring that the eccentric wheel 5 is always in contact with the same position on the lifting frame 2, thereby ensuring the rotation stability of the eccentric wheel 5, and providing a stronger guarantee for the smooth progress of the feeding process.

[0058] As shown in Figure 4 and Figure 9 , the application provides a specific embodiment based on the above embodiments as follows: The eccentric wheel 5 has two and is key connected at both ends of the lower guide rail shaft 8. The limiting plate 91 has two and corresponds to the eccentric wheel 5 one by one, and the two limiting plates 91 are respectively limited on the outer sides of the two eccentric wheels 5 away from each other, and the inner sides of the two eccentric wheels 5 close to each other are limited by the inner end of the key groove on the lower guide rail shaft 8.

[0059] When the lower guide rail shaft 8 is rotated by rotating the adjustment rod 61, the lower guide rail shaft 8 can simultaneously drive the two eccentric wheels 5 to rotate synchronously, and the two eccentric wheels 5 are simultaneously rotated towards the lifting frame 2, so that the force between the mounting frame 3 and the lifting frame 2 is more uniform, further improving the stability of the mounting frame 3 and the pitch adjustment process of the material plate 11.
