[0005] Beneficial Effects
[0006] The utility model provides a positioning device for metal plates used in welding large structural parts, and has the following beneficial effects compared with the prior art:
[0007] Related technicians place the two plates to be welded on two support plates respectively, making them abut against the ejector rod, and start manually rotating the handwheel on the left-handed screw rod, so that the left-handed screw rod drives the right-handed screw rod fixedly connected thereto to rotate synchronously, thereby causing the sliding cylinders threadedly connected to the left-handed screw rod and the right-handed screw rod to start linear movement along their connection with the connecting frame, so that the two sliding cylinders drive the clamping plates fixedly connected thereto to move towards each other, so that the two clamping plates cooperate with each other to center-align the plates to prevent the plates from not being aligned. At this time, the related technicians start the motor, so that the motor drives the gear meshed with its output gear to rotate synchronously, so that the gear drives the screw rod fixedly connected to its axis to start rotating, so that the sliding cylinder threadedly connected to the screw rod starts to move, causing the sliding cylinder to drive the sliding rod fixedly connected thereto to start linear movement along its connection with the support plate, so that the sliding rod drives the support rod hinged thereto to move synchronously, so that the support plate starts to perform circular movement with the hinge with the base as the fulcrum, thereby lifting the plate placed thereon.

Detailed Description of the Preferred Embodiments
[0013] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0014] The following describes in detail the specific implementation of the present utility model with reference to specific embodiments.
[0015] Please refer to Figures 1 to 4 , a metal sheet positioning device for welding large structural components provided by an embodiment of the present utility model, including a base 101, and further including:
[0016] A positioning component 2 for providing support to large sheets;
[0017] The positioning component 2 includes a support plate 201, a sliding rod 202, and a support rod 203. The two support plates 201 are respectively hinged on both sides of the base 101. A sliding rod 202 is slidably connected to the support plate 201. One end of the support rod 203 is hinged to the sliding rod 202, and the other end of the support rod 203 is hinged to the base 101.
[0018] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific support rod 203 described in the above embodiment. For example, the support rod 203 is made of a material with high hardness processed integrally, and the hinge joints at both ends are further hardened and reinforced. The purpose of this setting is to facilitate increasing the weighing capacity of the device in this way, so as to prevent the device from collapsing during the process of supporting the sheet.
[0019] Specifically, a sliding cylinder 204 is fixedly connected to the sliding rod 202. The sliding cylinder 204 is threadedly connected to a lead screw 205. The lead screw 205 is rotatably connected in the support plate 201.
[0020] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific lead screw 205 described in the above embodiment. For example, the lead screw 205 can be a reciprocating lead screw. The purpose of this setting is that when the sliding cylinder 204 threadedly connected to it moves to one end, the lead screw can be mechanically controlled to rotate in the same direction, so as to quickly change the movement direction of the sliding cylinder 204.
[0021] Specifically, a plurality of ejector rods 206 are fixedly connected to the sliding rod 202. A connecting frame 207 is fixedly connected to the tops of the plurality of ejector rods 206.
[0022] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific ejector rods 206 described in the above embodiment. For example, the ejector rods 206 can be provided with tooth-shaped stripes. The purpose of this setting is to facilitate increasing the limiting effect on the sheet in this way and preventing it from sliding.
[0023] Specifically, a left-handed lead screw 208 is rotatably connected in the connecting frame 207. The other end of the left-handed lead screw 208 is fixedly connected to a right-handed lead screw 209. The right-handed lead screw 209 is rotatably connected to the connecting frame 207.
[0024] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific left-handed lead screw 208 described in the above embodiments. For example, a hand crank is fixedly connected to the left-handed lead screw 208, and a grip rod is rotatably connected to the eccentric position of the hand crank. The purpose of this setting is to make it more labor-saving to rotate the left-handed lead screw 208 through this structure.
[0025] Specifically, sliding sleeves 301 are respectively threadedly connected to the left-handed lead screw 208 and the right-handed lead screw 209. The sliding sleeves 301 are slidably connected to the connecting frame 207, and clamping plates 302 are respectively fixedly connected to the two sliding sleeves 301.
[0026] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific clamping plate 302 described in the above embodiments. For example, the clamping plate 302 is made of hard steel. The purpose of this setting is to facilitate the selection of high-hardness materials to prevent deformation during the process of pushing the plate, so as to avoid the ineffective alignment of the plate.
[0027] Specifically, a plurality of shafts 304 are rotatably connected in the cavity of the support plate 201, and rollers 303 are respectively fixedly connected to the plurality of shafts 304.
[0028] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific roller 303 described in the above embodiments. For example, a plurality of dot-shaped protrusions are provided on the roller 303. The purpose of this setting is to facilitate increasing the friction between the roller 303 and the plate in this way.
[0029] Specifically, a gear 305 is fixedly connected to the lead screw 205. The gear 305 is meshed with a gear fixedly assembled on the output shaft of the motor 306, and the motor 306 is fixedly connected to the support plate 201.
[0030] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific motor 306 described in the above embodiments. For example, the motor 306 should be a motor with adjustable multi-speed. The purpose of this setting is to facilitate adjusting the motor output to prevent the plate from hitting and bumping.
[0031] In the embodiment of the present utility model, relevant technicians place the two plates to be welded on two support plates 201 respectively, make them abut against the ejector rod 206, and start manually rotating the handwheel on the left-handed screw rod 208, so that the left-handed screw rod 208 drives the right-handed screw rod 209 fixedly connected thereto to rotate synchronously, thereby causing the sliding cylinders 301 threadedly connected to the left-handed screw rod 208 and the right-handed screw rod 209 to start linear motion along the connection with the connecting frame 207, so that the two sliding cylinders 301 drive the clamping plates 302 fixedly connected thereto to move towards each other, so that the two clamping plates 302 cooperate with each other to center-align the plates to prevent the plates from being misaligned. At this time, the relevant technicians start the motor 306, so that the motor 306 drives the gear 305 meshed with its output gear to rotate synchronously, so that the gear 305 drives the screw rod 205 fixedly connected to its axis to start rotating, so that the sliding cylinder 204 threadedly connected to the screw rod 205 starts to move, so that the sliding cylinder 204 drives the sliding rod 202 fixedly connected thereto to start linear motion along the connection with the support plate 201, so that the sliding rod 202 drives the support rod 203 hinged thereto to move synchronously, so that the support plate 201 starts to perform circular motion with the hinge with the base 101 as the fulcrum, so as to lift the plate placed thereon. At the same time, the sliding rod 202 drives the ejector rod 206 fixedly connected thereto to move synchronously, so that the ejector rod 206 starts to push the plate to slide on the support plate 201. When the plates are lifted to a predetermined angle, the two plates are synchronously butted to facilitate welding and prevent gaps at the butting joints of the plates from affecting the welding.
[0032] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
[0033] The so-called fixed connection in this application means that after the parts or components are fixed, there is no relative movement connection. It is divided into two types: detachable connection and non-detachable connection.
[0034] (1) Detachable connection: Use screws, splines, wedge pins, etc. to fix the components together. This connection method can be disassembled during maintenance and will not damage the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedge pins), and they must be fastened properly.
[0035] (2) Non-detachable connection: mainly refers to welding, riveting, and mortise joint fitting, etc. Since for disassembly, forging, sawing, or oxygen cutting is required during maintenance or replacement, the spare parts generally cannot be reused. At the same time, during connection, attention should be paid to the process quality, technical inspection, and remedial measures (such as correction, polishing, etc.).
[0036] The sliding connection referred to in this application means that a component can slide along a linear trajectory, and the hinged connection referred to in this application means that a component can rotate along an axial constraint.
[0037] In some cases, the sliding connection and the hinged connection referred to in this application can also be damped, so that the component has the ability to maintain at a desired position.
[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
