Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a tooling device used for assembling a telescopic arm of a forklift. Background Art

[0002] The telescopic arm of a forklift is a key component of a forklift. The important components of the telescopic arm of a forklift include the arm head and the arm tube. Since the assembly between the various parts of the arm head and the arm tube involves the assembly of multiple components in different positions, in order to avoid the arm head and the arm tube of the forklift telescopic arm from twisting, swinging and deflecting after assembly, it is necessary to accurately position the arm head and the arm tube and other related components before welding, and correct the installation position and installation direction of the components, so as to ensure the performance of the telescopic arm of the forklift.

[0003] Firstly, at present, when assembling the arm head and the arm tube of the telescopic arm of a forklift, since the various parts of the arm head and the arm tube need to be positioned and abutted, and the tooling currently used for assembling the forklift mechanical arm requires an adjustment mechanism to position and abut the arm head and the arm tube, the process is not only cumbersome and time-consuming; moreover, when the adjustment mechanism is used, the arm head and the arm tube need to be placed on a workbench to complete the operation, and the assembly efficiency is low.

[0004] Secondly, even after the arm head and the arm tube are assembled, the positioning dimensions of the different positions of the arm head components need to be determined to ensure that the space parallelism and size linkage of the connection between the top and bottom of the arm head and the arm tube can ensure that the arm head and the arm tube of the forklift telescopic arm will not be twisted, swung or bent after assembly. However, since the adjustment mechanism is only assembled between the arm head and the arm tube, and after the assembly is completed, the adjustment mechanism is only positioned and abutted in one direction when it is moved step by step to different components, and the space parallelism and size linkage of the connection between the top and bottom of the arm head and the arm tube cannot be well guaranteed, which can easily lead to rough assembly or even wrong installation. Utility Model Content

[0005] In order to solve the defects of the prior art, an embodiment of the utility model provides a tooling device for assembling a telescopic arm of a forklift.

[0006] The embodiment of the utility model adopts the following technical scheme: a tooling device for assembling a telescopic arm of a forklift, the telescopic arm of the forklift includes an arm tube and an arm head, the arm head includes, from top to bottom, a support guard plate with a first through hole, a bent side plate and a lower sleeve of the arm head for assembling the arm tube; the tooling device is a cabinet structure, including, from top to bottom, a support ring provided with a first through hole for positioning and abutting the support guard plate, an upper side positioning plate installed for positioning and abutting the side of the bent side plate, an end stop positioning plate for positioning and abutting the front of the bent side plate, a lower positioning connection mechanism for positioning and abutting the lower sleeve of the arm head, and a convex bottom plate connected to the lower positioning connection mechanism for supporting the arm tube and preventing the arm tube from sliding.

[0007] Effect: When assembling the telescopic arm, place the arm tube on the ground and abut against the convex bottom plate, and use the lower positioning mechanism to position and abut against the arm tube, place the lower sleeve of the arm head against the connection with the arm tube, and use the lower positioning mechanism to connect the arm tube and the lower sleeve of the arm head accordingly. Then use the upper side positioning plate and the end stop positioning plate to position and abut against the bent side plate from multiple surfaces such as the side and the front, respectively, to maintain the spatial parallelism and dimensional linkage of the connection between the bent side plate and the arm head and the arm tube; finally, use the support ring to position and abut against the first through hole of the support guard plate to achieve the effect of supporting the support guard plate, connect the support guard plate with the bent side plate, and maintain the spatial parallelism and dimensional linkage of the connection between the support guard plate and the arm head and the arm tube. Only by such a step-by-step and multi-faceted positioning setting can the telescopic arm be accurately assembled.

[0008] At the same time, when installing the telescopic arm step by step from bottom to top, it is only necessary to position and abut each component of the telescopic arm against each positioning component of the tooling device, so as to greatly reduce the difficulty of assembly and efficiently assemble the telescopic arm while ensuring accuracy and no misassembly.

[0009] Preferably, the lower positioning connection mechanism includes: two first supporting vertical plates fixedly mounted on the convex bottom plate; positioning baffles fixedly connected to the first supporting vertical plates and the bottom plate of the tooling device, respectively, and symmetrical second through holes respectively opened on the two first supporting vertical plates, and a hollow cylindrical lower positioning seat sleeve fixedly connected to the second through holes.

[0010] Effect: The lower positioning connection mechanism is used to assemble the lower sleeve of the arm head and the arm tube more accurately and quickly. The lower positioning seat sleeve is a tooling component used to connect the arm head sleeve and the arm tube with a pin, and the positioning baffle is used to pre-position the arm tube and the tooling device, so that the lower positioning seat sleeve can accurately align with the connection between the lower sleeve of the arm head and the arm tube.

[0011] Preferably, it comprises a positioning beam exposed outwardly, the positioning beam is located between the end stop positioning plate and the support ring, and corresponds to the upper side positioning plate.

[0012] Effect: Since the bent side plate of the arm head and the supporting guard plate of the arm head are set at an obtuse angle, the upper side positioning plate needs to be positioned by a positioning beam and abutted against the inner side of the bent side plate.

[0013] Preferably, the height of the end stop positioning plate is not less than 100 mm.

[0014] Effect: Since the lateral contact area between the front edge of the bent side panel and the end stop positioning plate is small, in order to better support the bent side panel, the height of the end stop positioning plate is increased, thereby increasing the contact area with the front edge of the bent side panel, making it less likely for the bent side panel to shake or move during assembly.

[0015] Preferably, the length of the lower positioning seat sleeve is 176 mm.

[0016] Effect: The function of the lower locating seat sleeve is to limit the assembly spacing size of the arm head lower sleeve structure to 176mm, ensuring the accuracy of the arm head lower sleeve assembly and the parallelism of the end face.

[0017] Preferably, the lower positioning connection mechanism is symmetrical, and the symmetry plane of the lower positioning connection mechanism is 50 mm away from the symmetry plane between the two support rings.

[0018] Effect: Since the distance between the first through hole in the arm head support guard plate and the length of the arm head lower sleeve are inconsistent and do not share the same symmetry plane, the spacing between the symmetry plane of the lower positioning connection mechanism and the symmetry plane between the two support rings can achieve the effect of accurately assembling the telescopic arm.

[0019] Preferably, it also includes a support mechanism for stabilizing the tooling device of the cabinet structure, wherein the support mechanism includes a plurality of support beams fixedly installed in the cabinet and a plurality of second support vertical plates fixedly installed outside the cabinet.

[0020] Effect: The supporting crossbeam can increase the overall stability of the cabinet from the inside; the second supporting vertical plate can increase the overall stability of the cabinet from the outside. That is, the supporting mechanism can increase the overall stability of the cabinet from both the inside and outside, reduce the risk of cabinet deformation, and thus extend the service life of the cabinet.

[0021] Preferably, the height of the tooling device is not less than 1000 mm.

[0022] Effect: The height limit of 1000mm can ensure the spatial parallelism and dimensional linkage between the arm head and the arm tube, and further cooperate with the tooling device to position the various components to improve the accuracy of installation. At the same time, its height can meet the ergonomic design of normal adults, which can facilitate the staff to assemble the telescopic arm and improve the assembly efficiency. There is no need to use tools such as ladders to increase the height of the staff's working surface, which also ensures the construction safety of the staff to a certain extent.

[0023] Beneficial effects of the utility model

[0024] Firstly, compared with the existing telescopic arm assembly device, the assembly process using the adjustment mechanism is not only cumbersome and time-consuming, but also needs to be placed on the work surface to complete the assembly; since the telescopic arm needs to be assembled with many components, and the assembly device of the utility model is not limited to this structure, the utility model uses the various positioning components of the tooling device to correspond to the design of the different components of the telescopic arm in turn, thereby accurately ensuring the spatial linkage size of the top of the arm head and the connection between the arm head and the arm tube; at the same time, it is only necessary to place the arm tube and the lower sleeve of the arm head on the ground step by step and abut against the convex bottom plate, the positioning baffle plate and the lower positioning sleeve, and the assembly of the arm tube and the lower sleeve of the arm head can be completed simply and accurately through multi-faceted positioning, and then the end baffle positioning plate, the upper side positioning plate and the support ring are used to respectively position and abut against other parts to be assembled of the arm head, so that the telescopic arm can be assembled, and the process is simple, and the use of the tooling device can more efficiently assemble the telescopic arm. Through the various positioning components of the tooling device, each component to be assembled of the telescopic arm can be positioned and abutted in many aspects and directions, which can achieve the effect of preventing wrong installation.

[0025] Secondly, the height setting of the end stop positioning plate can also increase the contact area between the arm head to support and stabilize the arm head, and the contact position of the arm head and the arm tube can be stabilized by positioning the baffle plate to avoid shaking or rocking during the assembly process, thereby affecting the assembly accuracy.

[0026] Finally, since the telescopic boom tube and arm head are heavy, the setting of the support mechanism can improve the stability of the tooling device and extend the service life of the tooling device; in addition, by ergonomically designing the height of the assembly device, there is no need to use ladders or other tools to raise the height of the staff's working surface, thereby ensuring safety while improving assembly efficiency.
