Description

Technical Field

[0001] This invention belongs to the field of welding positioning technology, specifically relating to a series of positioning devices for welding production of assembled aerial work platforms. Background Technology

[0002] In the manufacturing process of aerial work platforms, the processing and welding of components play a crucial role. This process is extensive and highly complex. As a special vehicle used for high-altitude operations, aerial work platforms need to operate stably in various complex environments. Their components must not only bear their own weight but also withstand various external forces generated during high-altitude operations. Traditional production methods, which involve prefabricating components, cannot guarantee high consistency in size and shape. This can easily lead to interference between components, hindering successful assembly. The resulting inconsistent appearance quality severely impacts the overall aesthetics of the product, leading to multiple rework and repairs. Furthermore, repeated processing may damage the performance of components, ultimately affecting the overall performance of the aerial work platform. Therefore, the welding process has been improved by replacing welding with assembly, using corresponding workpieces to assemble the components. In the assembly of aerial work platform components, the control panel is an indispensable auxiliary tool. However, aerial work platform components are diverse in type and shape. To adapt to different components, corresponding special workpieces need to be installed. But whenever a component is to be assembled, the existing workpiece has to be disassembled and replaced with a new compatible workpiece. Currently, conventional disassembly and assembly tools use bolts or clamps. The whole process is cumbersome and complicated, consuming a lot of time and energy, and seriously affecting assembly efficiency.

[0003] Meanwhile, in assembling longer components, the length makes it difficult for workers to complete the entire assembly operation from a single location. They must constantly move around the workbench, shuttling between different positions to gradually complete the assembly task. This not only increases the workload of the workers but also easily leads to operational errors due to frequent movement, thereby affecting the assembly quality and posing potential risks to the overall performance and safety of the aerial work platform. Summary of the Invention

[0004] The purpose of this invention is to provide a series of positioning devices for welding production of assembled aerial work platforms, in order to solve the problems mentioned in the background art, such as the cumbersome and time-consuming disassembly and assembly of workpieces, and the need for frequent movement of long parts during assembly, which affect efficiency, quality and safety.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a positioning device for welding production series of assembled aerial work vehicles, the positioning device comprising a base, a disassembly and assembly mechanism, and mounting components; The disassembly and assembly mechanism is located on the top of the base; the disassembly and assembly mechanism consists of a snap-fit ​​component, a support component, a separation component, and a rotating disk; The snap-fit ​​assembly includes a snap-fit ​​part and an adjustment part; The snap-fit ​​part is located inside the support component, and one end extends laterally to the outside of the support component. The adjustment part is movably sleeved on the support component and reciprocates along the support component in the vertical direction. During the lifting and lowering process, the adjustment part drives the snap-fit ​​part to perform horizontal reciprocating motion. However, when the snap-fit ​​part is performing horizontal reciprocating motion, it does not drive the snap-fit ​​part to perform lifting and lowering motion. The bottom of the support assembly is fixed to the rotating disk; The separating component is sleeved between the supporting component and the rotating disk, and the bottom center of the separating component is threadedly connected to the supporting component, while the top center of the separating component is limitedly connected to the adjusting part. When the separating component rotates, it drives the adjusting part to move vertically up and down. The mounting component is fitted onto the supporting assembly and is horizontally inserted and locked by the snap-fit ​​part.

[0006] As a preferred technical solution of the present invention, the locking part includes a locking block and a spring; The top of the end of the card block that protrudes from the outside of the support component is arc-shaped, while the end face of the other end of the card block has a groove that connects the top and bottom. A moving groove is formed through the front surface of the card block, and the moving groove passes through the area of ​​the groove. One end of the spring is fixed to the end face of the other end of the block and distributed on both sides of the slot.

[0007] As a preferred technical solution of the present invention, the adjusting part includes a connecting sleeve, a connecting rod, and a shaft; The top edge of the connecting sleeve is provided with rotating grooves at equal angles, and an integral convex ring is fixed in the middle of the connecting sleeve. One end of the connecting rod is placed in the rotating groove, and the other end is placed in the groove at the other end of the locking block; the groove is designed to avoid affecting the rotation of the connecting rod. The shaft has two shafts, which pass through both ends of the connecting rod. One shaft is fixed to the inner wall of the rotating groove, while the other shaft moves through the moving groove and abuts against the inner wall of the through groove. Therefore, the connecting rod will only move when the connecting sleeve moves down.

[0008] As a preferred technical solution of the present invention, the supporting component includes a connecting plate and studs; The bottom end of the connecting plate is provided with a bottom groove, and the top inner wall of the bottom groove is also formed with a protrusion with a notch on one side. A through groove is provided on one side of the bottom groove, which extends to the outer surface of the connecting plate. The locking block reciprocates horizontally under the limiting position of the through groove, while the other end of the locking block is located in the bottom groove, and the other end of the spring is located in the recess of the protrusion. The stud is fixed at the center of the bottom end face of the connecting plate, and the connecting sleeve is sleeved on the stud. The two are either connected by a plane or not in contact, so as to ensure that the connecting sleeve will only move up and down along the stud in the vertical direction and will not be threaded to the stud.

[0009] As a preferred technical solution of the present invention, the area traversed by the top of the connecting rod during movement is smaller than the area formed by the bottom groove, while the bottom of the connecting rod does not contact the inner wall of the rotating groove during movement, thereby avoiding the phenomenon of movement obstruction.

[0010] As a preferred technical solution of the present invention, the separation component includes a toggle switch; The center of the dial has a stepped hole for accommodating the connecting sleeve. The bottom end face of the stepped hole forms a support portion, which is sleeved on the stud and threadedly connected to the stud. A limiting part is formed at the edge of the opening at the top of the stepped hole. This limiting part is locked onto the convex ring to limit the convex ring. When the position of the dial changes up and down, it will drive the connecting sleeve to rise and fall. The connecting sleeve will then control the extension and retraction of the locking block by pulling the connecting rod. During processing, the support part can be separated from the dial. The dial has a circular hole of equal diameter in the middle. The support part is then fixed by welding to ensure the normal installation of the connecting sleeve.

[0011] As a preferred technical solution of the present invention, the surface of the rotating disk is provided with a paving groove, and the bottom end of the stud is fixed on the paving groove; the paving groove has a notch; The actuating disc is located above the actuating groove, and part of the actuating disc protrudes from the notch of the actuating groove to the outside of the rotating disc. The outer surface of the actuating disc has concave or convex teeth to facilitate the rotation of the actuating disc.

[0012] As a preferred technical solution of the present invention, the base includes a base plate, a support plate, and a support ring; The base plate is placed on the ground, while the support plate is fixed at an equal angle on the base plate, and the support ring is fixed on the top surface of the support plate. The rotating disk is attached to the support ring.

[0013] As a preferred technical solution of the present invention, the top of the support ring is provided with an annular groove, and multiple balls are placed in the annular groove, which roll and fit against the bottom end surface of the rotating disk. A servo motor is also installed on the top of the base plate. The output end of the servo motor is fixedly connected to the bottom end face of the rotating disk. The servo motor can drive the rotating disk to rotate, so as to achieve the purpose of adjusting the position of the assembled parts later.

[0014] As a preferred technical solution of the present invention, the mounting component is a mounting plate. The mounting plate has alignment grooves on two adjacent sides, and screw holes are provided on the alignment grooves. When multiple mounting plates need to be spliced, metal parts with holes at both ends can be placed in the alignment grooves and then fixed and assembled by bolts to meet the assembly requirements of different parts. The bottom end face of the mounting plate has a mounting slot hole that fits on the connecting plate, and an insertion hole for the locking block to be inserted is provided inside the mounting slot hole.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In this invention, a disassembly and assembly mechanism is added, enabling rapid disassembly and assembly of mounting plates containing different workpieces. This greatly simplifies the operation process and significantly improves ease of operation compared to traditional methods relying on bolts or clamps. It also ensures the stability of the mounting plate after installation, effectively preventing loosening or shaking during assembly. When assembling larger parts, multiple mounting plates can be spliced ​​together. This allows for flexible adjustment of the assembly space according to the size and shape of different parts, greatly enhancing the versatility and flexibility of the device. Furthermore, when assembling longer parts, the device can rotate to adjust the part's position, eliminating the need for operators to move back and forth between different locations to complete the entire assembly task, making operation extremely convenient.

The stud 206 is fixed at the center of the bottom end face of the connecting plate 203, and the connecting sleeve 205 is sleeved on the stud 206. The two are either connected in a planar manner or not in contact, so as to ensure that the connecting sleeve 205 will only move up and down in the vertical direction along the stud 206 and will not be threaded to the stud 206.

[0023] In this embodiment, refer to Figure 7 The area traversed by the top of the connecting rod 207 during movement is smaller than the area formed by the bottom groove 203a, while the bottom of the connecting rod 207 does not contact the inner wall of the rotating groove 205b during movement, thereby avoiding the phenomenon of movement obstruction.

[0024] In this embodiment, refer to Figure 6 and Figure 7 The separation component includes a dial 202; The center of the dial 202 has a stepped hole for accommodating the connecting sleeve 205. The bottom end face of the stepped hole forms a support portion 202a, which is sleeved on the stud 206 and threadedly connected to the stud 206. A limiting part 202b is formed at the edge of the opening at the top of the stepped hole. This limiting part 202b is locked onto the convex ring 205a, thereby limiting the convex ring 205a. When the position of the dial 202 changes up and down, it will drive the connecting sleeve 205 to rise and fall. The connecting sleeve 205 will then control the extension and retraction of the locking block 204 by pulling the connecting rod 207. During processing, the supporting part 202a can be separated from the dial 202. The dial 202 has a circular hole of equal diameter in the middle. Then, the supporting part 202a is fixed by welding to ensure the normal installation of the connecting sleeve 205.

[0025] In this embodiment, refer to Figure 3 , Figure 4 The rotating disk 201 has a swivel groove 201a on its surface, and the bottom end of the stud 206 is fixed on the swivel groove 201a; the swivel groove 201a has a notch. The actuating disk 202 is located above the actuating groove 201a, and part of the actuating disk 202 protrudes from the notch of the actuating groove 201a to the outside of the rotating disk 201. The outer surface of the actuating disk 202 has concave or convex teeth to facilitate the rotation of the actuating disk 202.

[0026] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The base 100 includes a base plate 101, a support plate 102, and a support ring 103; The base plate 101 is placed on the ground, while the support plate 102 is fixed at an equal angle on the base plate 101, and the support ring 103 is fixed on the top surface of the support plate 102. The rotating disk 201 is attached to the support ring 103.

[0027] In this embodiment, refer to Figure 9 The top of the support ring 103 is provided with an annular groove, and a plurality of balls 103a are placed in the annular groove. The balls 103a roll and fit against the bottom end face of the rotating disk 201. A servo motor 400 is also installed on the top of the base plate 101. The output end of the servo motor 400 is fixedly connected to the bottom end face of the rotating disk 201. The servo motor 400 can drive the rotating disk 201 to rotate, so as to achieve the purpose of adjusting the position of the assembled parts later.

[0028] In this embodiment, refer to Figure 1 , Figure 2 , Figure 5 , Figure 10 The mounting component is a mounting plate 300. The mounting plate 300 has two adjacent sides with alignment grooves 301. The alignment grooves 301 have screw holes. When multiple mounting plates 300 need to be spliced, metal parts with holes at both ends can be placed in the alignment grooves 301 and then fixed and assembled by bolts to meet the assembly requirements of different parts. The bottom end face of the mounting plate 300 has a mounting slot 302 that fits on the connecting plate 203. Inside the mounting slot 302, there is an insertion hole 303 for the locking block 204 to be inserted.

[0029] The working principle of the positioning device is explained below: The limiting fixture for the parts to be assembled on the aerial work platform is first fastened to the mounting plate 300 by a clamp or other limiting component. The holes on the surface of the mounting plate 300 are used to assemble the clamp, and the holes can be machined into screw holes as required. If the parts to be assembled are large and a single mounting plate 300 cannot meet the installation of the limiting workpiece, a metal part with holes at both ends is placed in the alignment groove 301 to achieve splicing of multiple mounting plates 300. After installation, the mounting plate 300 with the limit fixture is placed on the connecting plate 203. At this time, the inner wall of the mounting slot 302 will first press the arc-shaped position of the locking block 204, causing the locking block 204 to move towards the bottom groove 203a and press the spring 208. Meanwhile, the shaft 209 at the top of the connecting rod 207 will move in the moving groove 204a. At this time, the entire connecting rod 207 will not move. When the mounting slot 302 is aligned with the locking block 204, the locking block 204 will pop out under the rebound of the spring 208, thus locking the mounting plate 300. Then, the subsequent assembly is carried out. During the assembly, the servo motor 400 drives the rotating disk 201 to rotate, and the rotating disk 201 drives the entire disassembly and assembly mechanism to move, so as to adjust the angle of the assembled parts. During disassembly, rotate the dial 202. The dial 202 rotates downward along the thread of the stud 206. At this time, the limiting part 202b will press down the convex ring 205a. The convex ring 205a will drive the bottom of the connecting rod 207 to move downward. At this time, the top of the connecting rod 207 moves the locking block 204 toward the bottom groove 203a through the shaft 209 until the locking block 204 separates from the mounting slot 302. Then, the mounting plate 300 can be removed from the connecting plate 203. Finally, rotate the dial 202 upward to return it to its original position.

[0030] Although embodiments of the invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
