Description

Technical Field

[0001] This utility model relates to the field of carriage processing technology, specifically a positioning device for carriage welding processing. Background Technology

[0002] In the production and processing of the carriage, the carriage panels are usually processed first and then assembled together. Many parts on the carriage panels are fixed to the carriage panels by welding. When these parts need to be welded, the carriage panels need to be fixed by positioning devices.

[0003] Publication No. CN218081070U discloses a welding fixture for processing a car body. This device uses a pull rod to prevent the protective door from contacting the worktable. When the sliding rod is pulled outside the worktable, its rotation drives a second lead screw, which in turn drives a sliding plate on the worktable. This causes the plate to move towards a clamping structure on one side of the worktable, placing the car body panel onto it. A support plate on the worktable reduces the pressure of the car body panel on the worktable. A gripping rod drives a first lead screw, which moves a pressure plate towards the car body panel. When the plate reaches a certain position, it is fixed in place. The second lead screw allows for quick adjustment of the clamping structure's position, enabling the fixing of car body panels of different widths, thus saving adjustment time and improving work efficiency and the flexibility of the welding fixture. However, this patent still has the following problems in practical use:

[0004] The device reduces the pressure of the carriage panel on the workbench by using a support plate. The lever drives the first lead screw to rotate, which moves the pressure plate toward the carriage panel, thus fixing the carriage panel. The position of the clamping structure can be quickly adjusted by the second lead screw to fix carriage panels of different widths. However, the device does not have the effect of quickly positioning the carriage panel, so the operator needs to constantly adjust multiple sets of lead screws and other structures, which greatly increases the cumbersomeness of positioning the carriage panel, reduces the flexibility of the equipment, and causes inconvenience to the operator.

[0005] A positioning device for welding and processing carriages is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a positioning device for welding and processing carriages, in order to solve the problem mentioned in the background art. Currently, the support plate on the workbench can reduce the pressure of the carriage panel on the workbench. At this time, rotating the handle will drive the first lead screw to rotate. The first lead screw will move the pressure plate toward the carriage panel. When it moves to a certain position, the carriage panel is fixed. Then, the position of the clamping structure can be quickly adjusted by the second lead screw to fix carriage panels of different widths. However, this device does not have the effect of quickly positioning the carriage panel. Therefore, the operator needs to constantly adjust multiple sets of lead screws and other structures, which greatly increases the cumbersomeness of positioning the carriage panel and reduces the flexibility of equipment use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for welding and processing carriages, including a worktable, wherein support legs are symmetrically fixedly installed on the bottom of the worktable; a positioning mechanism is symmetrically arranged on the top of the worktable, and a limit component is provided at the center of the top of the worktable;

[0008] The positioning mechanism includes a sliding box, which is symmetrically and fixedly installed on the top of the worktable. A strip box is fixedly connected to one side of the sliding box, and a screw is symmetrically and rotatably connected between the sliding box and the strip box. A movable plate is provided inside the sliding box, and threaded sleeves are symmetrically and fixedly installed at both ends of the movable plate. The threaded sleeves are located outside the screw and are threadedly connected to the screw. A drive rod is rotatably connected inside the strip box, and a first forward and reverse motor is fixedly connected to one end of the drive rod. A first conical tooth is symmetrically and fixedly installed at both ends of the drive rod, and a second conical tooth is fixedly installed at one end of the screw. An adjusting plate is fixedly connected to one side of the movable plate, and one end of the adjusting plate passes through the sliding box and is slidably connected to the sliding box. An L-plate is fixedly connected to the side of the adjusting plate away from the movable plate.

[0009] Preferably, an electric telescopic rod is fixedly installed on the top of the L-plate, and a horizontal plate is fixedly connected to the output end of the electric telescopic rod. A pressing rod is symmetrically fixedly connected to the bottom of the horizontal plate, and the bottom of the pressing rod penetrates through the L-plate and is slidably connected to the L-plate. A pressing plate is fixedly connected between the bottoms of the pressing rods, and a first rubber plate is fixedly installed on the bottom of the pressing plate.

[0010] Preferably, the limiting component includes a sliding groove formed on the top of the worktable, and a bidirectional threaded rod is rotatably connected between the sliding groove and the worktable. Threaded blocks are symmetrically threaded at both ends of the bidirectional threaded rod. A push plate is fixedly installed on the top of the threaded blocks, and a rubber pad is fixedly connected to one side of the push plate. A second forward and reverse motor is fixedly connected to one end of the bidirectional threaded rod.

[0011] Preferably, the top of each workbench is symmetrically provided with limiting grooves, and the bottom of the push plate is symmetrically fixedly connected with limiting blocks, and the outside of the limiting blocks is slidably connected to the inside of the limiting grooves.

[0012] Preferably, a second rubber plate is embedded on the inner side of the L plate.

[0013] Preferably, the external part of the drive rod is engaged with a limiting plate, and the external part of the limiting plate is fixedly connected to the internal part of the strip box.

[0014] Preferably, the first conical tooth and the second conical tooth are engaged in a meshing connection.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The positioning device for welding and processing a carriage, specifically, involves the following: the forward rotation of a first positive and negative motor drives the rotation of a drive rod; the rotation of a first conical tooth drives the rotation of a second conical tooth; the rotation of the second conical tooth drives the synchronous and co-directional rotation of two sets of screws; the rotation of the screws drives the movement of a threaded sleeve; and the movement of the threaded sleeve causes the moving plate and adjusting plate to slide inside the sliding box. At this time, the two sets of L-plates approach each other and press and limit the sides of the carriage panel, thereby achieving the effect of quickly adjusting and positioning the carriage panel. Furthermore, the operator can adjust and position the carriage panel according to its specifications. This greatly increases the flexibility of the device during use, making it more convenient than the existing technology that requires the operation of multiple drive components. It also improves the efficiency of continuous production welding of the carriage panels. The operation of the second positive and negative motor drives the bidirectional threaded rod to rotate inside the sliding groove. The rotation of the bidirectional threaded rod drives the movement of two sets of threaded blocks. The movement of the threaded blocks drives the movement of the push plate. The movement of the push plate causes the rubber pad to squeeze and position the two ends of the carriage panel, thereby achieving the effect of quickly squeezing and limiting the two ends of the carriage panel. This effectively avoids the phenomenon of carriage panel displacement caused by external force collisions, thus greatly improving the stability of the carriage panel during welding.

[0016] 1. The forward rotation of the first forward and reverse motor drives the rotation of the drive rod, which in turn drives the rotation of two sets of first conical teeth. The rotation of the first conical teeth drives the rotation of the second conical teeth, which in turn drives the synchronous and co-directional rotation of two sets of screws. The rotation of the screws drives the movement of the threaded sleeve, which in turn causes the moving plate and adjusting plate to slide inside the sliding box. The movement of the adjusting plate drives the movement of the L-plate. At this time, the two sets of L-plates move closer together, pressing and limiting the sides of the carriage panel, thus achieving the effect of quickly adjusting and positioning the carriage panel. Furthermore, the operator can adjust and position the panel according to its specifications, greatly increasing the flexibility of the device during use, compared to existing technologies that require the operation of multiple components. The driving method is more convenient and improves the efficiency of continuous production welding of the carriage panels. The electric telescopic rod is driven by the operator to operate the controller. The operation of the electric telescopic rod drives the horizontal plate to move. The movement of the horizontal plate drives the two sets of extrusion rods to slide inside the L plate. The movement of the L plate drives the extrusion plate to move up and down. The movement of the extrusion plate drives the first rubber plate to extrude and limit the top edges of both sides of the carriage panel. At this time, the first rubber plate is deformed by extrusion, thereby achieving the effect of quickly extruding and positioning the top edges of both sides of the carriage panel. This greatly improves the stability of the carriage panel during positioning welding. The operator can also adjust the height of the extrusion plate according to the thickness of the carriage panel, further improving the flexibility of the equipment during use.

[0017] 2. The operation of the second positive and negative motor drives the bidirectional threaded rod to rotate inside the sliding groove. The rotation of the bidirectional threaded rod drives the movement of two sets of threaded blocks. The movement of the threaded blocks drives the movement of the push plate. The movement of the push plate drives the rubber pad to squeeze and position the two ends of the carriage panel. This achieves the effect of quickly squeezing and limiting the two ends of the carriage panel, thereby effectively avoiding the phenomenon of carriage panel displacement caused by external force collisions, and thus greatly improving the stability of the carriage panel during welding.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides a technical solution: a positioning device for welding processing of carriages, including a workbench 1, with support legs 101 symmetrically fixedly installed on the bottom of the workbench 1; a positioning mechanism 2 is symmetrically arranged on the top of the workbench 1, and a limit component 3 is arranged at the center of the top of the workbench 1.

[0026] The positioning mechanism 2 includes a sliding box 201, which is symmetrically and fixedly installed on the top of the workbench 1. A strip box 202 is fixedly connected to one side of the sliding box 201. A screw 203 is symmetrically and rotatably connected between the sliding box 201 and the strip box 202. A movable plate 204 is provided inside the sliding box 201, and threaded sleeves 205 are symmetrically and fixedly installed at both ends of the movable plate 204. The threaded sleeves 205 are located outside the screw 203 and are threadedly connected to the screw 203. A drive rod 206 is rotatably connected inside the strip box 202. A first forward and reverse motor 207 is fixedly connected to one end of the drive rod 206, and a first cone is symmetrically and fixedly installed at both ends of the drive rod 206. The device has a first conical tooth 208 and a second conical tooth 209 fixedly installed at one end of the screw 203. The first conical tooth 208 and the second conical tooth 209 are meshed together. An adjusting plate 210 is fixedly connected to one side of the moving plate 204. One end of the adjusting plate 210 passes through the sliding box 201 and is slidably connected to the sliding box 201. An L-plate 211 is fixedly connected to the side of the adjusting plate 210 away from the moving plate 204. This enables the device to quickly adjust and position the carriage panel. The operator can adjust and position the carriage panel according to its specifications, which greatly increases the flexibility of the device. Compared with the existing technology, which requires the operation of multiple components, this device is more convenient and improves the efficiency of continuous production welding of carriage panels.

[0027] An electric telescopic rod 212 is fixedly installed on the top of the L-plate 211, and a horizontal plate 213 is fixedly connected to the output end of the electric telescopic rod 212. A pressing rod 214 is symmetrically fixedly connected to the bottom of the horizontal plate 213, and the bottom of the pressing rod 214 penetrates through the L-plate 211 and is slidably connected to it. A pressing plate 215 is fixedly connected between the bottoms of the pressing rods 214, and a first rubber plate 216 is fixedly installed on the bottom of the pressing plate 215. This allows for rapid pressing and positioning of the top edges on both sides of the carriage panel, thereby greatly improving the positioning of the carriage panel. To improve stability during welding, workers can adjust the height of the extrusion plate 215 according to the thickness of the carriage panel, further enhancing the flexibility of equipment use. The inner side of the L-plate 211 is inlaid with a second rubber plate 217. The design of the second rubber plate 217 can prevent the L-plate 211 from rigidly extruding the sides of the carriage panel, thus avoiding damage. The external drive rod 206 is engaged with the limit plate 218, and the external limit plate 218 is fixedly connected to the inside of the strip box 202. The design of the limit plate 218 makes the rotation of the drive rod 206 more stable.

[0028] The limiting component 3 includes a sliding groove 301 formed on the top of the workbench 1, and a bidirectional threaded rod 302 is rotatably connected between the sliding groove 301 and the workbench 1. Threaded blocks 303 are symmetrically threaded to both ends of the bidirectional threaded rod 302. A push plate 304 is fixedly mounted on the top of the threaded blocks 303, and a rubber pad 305 is fixedly connected to the corresponding side of the push plate 304. A second forward and reverse motor 306 is fixedly connected to one end of the bidirectional threaded rod 302, thereby enabling rapid compression and limiting of both ends of the carriage panel. The positioning effect effectively avoids the phenomenon of the carriage panel shifting due to external force collision, thereby greatly improving the stability of the carriage panel during welding. The top of the workbench 1 is symmetrically provided with limiting grooves 307, and the bottom of the push plate 304 is symmetrically fixedly connected with limiting blocks 308. The outside of the limiting blocks 308 is slidably connected to the inside of the limiting grooves 307. The movement of the push plate 304 drives the two sets of limiting blocks 308 to slide inside the limiting grooves 307, thereby improving the stability of the push plate 304 during movement.

[0029] Working principle: Before using this positioning device for welding and processing carriages, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, the operator first places the equipment in the work area, using four support legs 101 to support the workbench 1. Then, the operator places the carriage panel to be welded on the top center area of ​​the workbench 1. The operator operates the controller to drive the two sets of first forward and reverse motors 207 to rotate in both directions. The forward rotation of the first forward and reverse motors 207 drives the rotation of the drive rod 206, which in turn drives the rotation of the two sets of first conical teeth 208. The rotation of the first conical teeth 208 drives the rotation of the second conical teeth 209, which in turn drives the rotation of the second conical teeth 209. The rotation of screw 9 drives the two sets of screws 203 to rotate synchronously and in the same direction. The rotation of screw 203 drives the movement of threaded sleeve 205. The movement of threaded sleeve 205 drives moving plate 204 and adjusting plate 210 to slide inside sliding box 201. The movement of adjusting plate 210 drives L-plate 211 to move. At this time, the two sets of L-plates 211 move closer to each other and squeeze and limit the sides of the car body panel, thereby achieving the effect of quickly adjusting and positioning the car body panel. Moreover, the operator can adjust and position according to the specifications of the car body panel, which greatly increases the flexibility of the device during use. This technology is more convenient than existing technologies that require the operation of multiple components, improving the efficiency of continuous welding of the carriage panels. The electric telescopic rod 212 is driven by a controller operated by the operator. The operation of the electric telescopic rod 212 moves the horizontal plate 213, which in turn moves the two sets of extrusion rods 214 inside the L-plate 211. The movement of the L-plate 211 causes the extrusion plate 215 to move up and down. The movement of the extrusion plate 215 causes the first rubber plate 216 to extrude and limit the top edges of both sides of the carriage panel. At this time, the first rubber plate 216 is deformed by the extrusion, thus achieving rapid extrusion and positioning of the top edges of both sides of the carriage panel, greatly improving the stability of the carriage panel during positioning welding. The operator can also adjust the height of the extrusion plate 215 according to the thickness of the carriage panel, further improving the flexibility of the equipment. The design of the second rubber plate 217 avoids damage caused by the rigid extrusion of the L-plate 211 on both sides of the carriage panel. The design of the limiting plate 218 makes the rotation of the drive rod 206 more stable.

[0030] The second forward and reverse motor 306 is driven to rotate in both directions by the operator's controller. The operation of the second forward and reverse motor 306 drives the bidirectional threaded rod 302 to rotate inside the sliding groove 301. The rotation of the bidirectional threaded rod 302 drives the movement of two sets of threaded blocks 303. At this time, the two sets of threaded blocks 303 move in a convergence and unfolding trajectory. The movement of the threaded blocks 303 drives the push plate 304 to move. The movement of the push plate 304 drives the rubber pad 305 to squeeze and position the two ends of the carriage panel, thereby achieving the effect of quickly squeezing and limiting the two ends of the carriage panel. This can effectively avoid the phenomenon of carriage panel displacement caused by external force collision, thus greatly improving the stability of the carriage panel during welding. The movement of the push plate 304 drives the two sets of limiting blocks 308 to slide inside the limiting groove 307, thereby improving the stability of the push plate 304 during movement.
