Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and in particular relates to a tie rod assembly riveting device. Background Technology

[0002] The production process of a machine refers to the entire process of transforming raw materials (or semi-finished products) into finished products. For machine production, this includes the transportation and storage of raw materials, production preparation, blank manufacturing, parts processing and heat treatment, product assembly and debugging, painting, and packaging. The production process is very broad, and modern enterprises use the principles and methods of systems engineering to organize and guide production, viewing the production process as a production system with inputs and outputs.

[0003] Existing tie rod assembly riveting mechanisms are usually fixed, and the limiting mechanisms used in conjunction with them are also in relatively fixed positions. As a result, when different tie rods need to be stamped, it is necessary to adjust the corresponding positions of the stamping-related mechanisms, which is cumbersome and has low adaptability. In order to avoid the above situation, it is necessary to provide a tie rod assembly riveting device with higher applicability. Utility Model Content

[0004] This utility model provides a tie rod assembly riveting device, which aims to solve the problem that the existing tie rod assembly riveting mechanism is usually fixed, and the limiting mechanism used with it is also fixed in a relatively fixed position. As a result, when different tie rods need to be stamped, it is necessary to adjust the corresponding position of the stamping mechanism, which is cumbersome to operate and has low adaptability.

[0005] This utility model is implemented as follows: a tie rod assembly pressing and riveting device includes a base: an upper support frame assembly is provided on the top of the base, a pressing and riveting assembly is provided on the outer wall of the upper support frame assembly, and a side limiting assembly is fixedly connected to the outer side of the base.

[0006] The riveting assembly includes an upper slide block, a transmission mechanism is fixedly connected to the front and rear sides of the upper slide block, an upper lifting hydraulic cylinder is fixedly connected to the bottom of the upper slide block, and a stamping machine is fixedly connected to the bottom of the upper lifting hydraulic cylinder.

[0007] The upper support frame assembly includes a side bracket fixedly mounted on the outer wall of the pedestal, and a side limiting seat mechanism and a slide rail are fixedly connected to the top of the side bracket.

[0008] Preferably, the transmission mechanism includes a motor fixedly mounted on the outer wall of the upper slide, and the output shaft of the motor is fixedly connected to a small roller via a coupling.

[0009] Preferably, the side limiting seat mechanism includes a side limiting seat fixedly mounted on the side support, and the inner wall of the side limiting seat is movably connected with several rollers.

[0010] Preferably, the outer wall of the slide rail is slidably connected to the inner wall of the upper slide block.

[0011] Preferably, the side limiting assembly includes a positioning plate fixedly mounted on the base, a side telescopic hydraulic cylinder is fixedly connected to one side of the positioning plate, and a retainer is fixedly connected to one end of the side telescopic hydraulic cylinder;

[0012] Several arc-shaped slots are provided on one side of the card holder.

[0013] Preferably, there are multiple side limiting components, and the multiple side limiting components are symmetrically arranged on the outer wall of the base.

[0014] Preferably, a support column is fixedly connected to the bottom of the pedestal, and a base is fixedly connected to the bottom of the support column.

[0015] Preferably, the outer wall of the chassis is provided with a mounting ring groove, and the inner wall of the mounting ring groove is provided with a positioning hole perpendicularly downward.

[0016] Compared with the prior art, the embodiments of this application have the following main advantages:

[0017] The riveting assembly is the core actuator of this device, and its integrated and modular design brings multiple significant benefits. Firstly, it provides stable and powerful downward pressure through an upward-lifting hydraulic cylinder, ensuring that the press can accurately and efficiently press the rivets into the tie rod, resulting in a strong, reliable, and consistent riveting joint. Secondly, its unique transmission mechanism drives the upper slide to move along a preset slide rail, achieving precise and flexible horizontal positioning of the riveting head. Compared to simple manual or fixed riveting, this design eliminates the need to re-clamp the workpiece; simply moving the riveting head quickly aligns different riveting points, greatly improving processing efficiency and automation, making it particularly suitable for multi-position or batch riveting operations.

[0018] The upper support frame assembly serves as the load-bearing and guiding skeleton of the device, offering key benefits in terms of high stability and precise guidance. It constructs a robust top frame through side supports, providing a stable and reliable installation foundation and elevated working space for the riveting assembly. This effectively absorbs the significant reaction forces and vibrations generated during riveting, ensuring a smooth processing flow. Simultaneously, the sliding engagement between its slide rail and upper slide provides high-precision linear guidance for the movement of the riveting assembly, ensuring the press maintains a vertical orientation in any position, thus guaranteeing the verticality and positional accuracy of the riveting. Rollers in the side limiting seat mechanism further assist in guidance and support, reducing friction and making the movement of the riveting assembly smoother and more precise.

[0019] The side-limiting component offers the key advantage of enabling rapid, adaptive, and non-destructive clamping of the workpiece. Driven linearly by a side-telescopic hydraulic cylinder, it automatically centers and clamps tie rods of varying sizes. Its arc-shaped groove design perfectly conforms to the outer contour of cylindrical tie rods, providing ample clamping force while avoiding stress concentration or scratching the workpiece surface, thus achieving flexible clamping. Multiple components are symmetrically arranged on the outside of the platform, applying force evenly from both sides simultaneously. This ensures the tie rod is firmly restrained at the center of the platform and aligned with the press, effectively preventing workpiece displacement or loosening during riveting. This is crucial for ensuring accurate riveting positioning and operational safety. Attached Figure Description

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] This utility model embodiment provides a tie rod assembly riveting device, including a base 1: an upper support frame assembly 3 is provided on the top of the base 1, a riveting assembly 2 is provided on the outer wall of the upper support frame assembly 3, and a side limiting assembly 4 is fixedly connected to the outer side of the base 1.

[0029] The riveting assembly 2 includes an upper slide 201, a transmission mechanism 202 is fixedly connected to the front and rear sides of the upper slide 201, an upper lifting hydraulic cylinder 203 is fixedly connected to the bottom of the upper slide 201, and a punching machine 204 is fixedly connected to the bottom of the upper lifting hydraulic cylinder 203.

[0030] The upper support frame assembly 3 includes a side bracket 303 fixedly installed on the outer wall of the base 1. The top of the side bracket 303 is fixedly connected to a side limiting seat mechanism 301 and a slide rail 302.

[0031] The transmission mechanism 202 includes a motor fixedly mounted on the outer wall of the upper slide 201, and the output shaft of the motor is fixedly connected to a small roller via a coupling.

[0032] The side limiting seat mechanism 301 includes a side limiting seat 3011 fixedly mounted on the side bracket 303, and several rollers 3012 are movably connected to the inner wall of the side limiting seat 3011.

[0033] The outer wall of the slide rail 302 is slidably connected to the inner wall of the upper slide block 201.

[0034] A support column 5 is fixedly connected to the bottom of the base 1, and a chassis 6 is fixedly connected to the bottom of the support column 5.

[0035] The outer wall of the chassis 6 is provided with a mounting ring groove, and the inner wall of the mounting ring groove is provided with a positioning hole perpendicularly downward.

[0036] It should be noted that since the existing tie rod assembly riveting mechanism is usually fixed, the limiting mechanism used with it is also in a relatively fixed position. Therefore, when different tie rods need to be stamped, the corresponding positions of the stamping mechanism need to be adjusted, which is relatively troublesome and has low adaptability.

[0037] Specifically, in this embodiment, the solution mainly utilizes the setup and coordination of the platform 1, upper support frame assembly 3, riveting assembly 2, and side limiting assembly 4. In use, the tie rod to be riveted is placed on the platform 1 with the riveting position facing upwards, the rivet is positioned, and then the side telescopic hydraulic cylinder 402 is activated and controlled to move the clamping seat 403. The clamping seat 403 fixes and limits the tie rod on both sides, ensuring that the tie rod is positioned in the middle of the platform 1 and corresponds to the stamping machine 204. Then, the electric motor is started and controlled to drive the small roller to rotate, thereby enabling the riveting assembly 2 to travel along the slide rail 302 until the stamping machine 204 and the rivet are on the same vertical straight line. The lifting hydraulic cylinder 203 is started to move the stamping machine 204 so that the stamping machine 204 is close to the rivet. The stamping machine 204 is started to perform riveting, pressing the rivet into the pull rod to complete the operation. The side limiting seat mechanism 301 on both sides can provide a good limiting support effect for the riveting assembly 2.

[0038] In this embodiment, the riveting assembly 2 is the core actuator of the device, and its integrated and modular design brings multiple significant benefits. First, it provides stable and powerful downward pressure through the lifting hydraulic cylinder 203, ensuring that the press 204 can accurately and efficiently press the rivet into the tie rod, resulting in a firm, reliable, and consistent riveting joint. Second, its unique transmission mechanism 202 drives the upper slide block 201 to move along the preset slide rail 302, realizing precise and flexible positioning of the riveting head press in the horizontal direction. Compared with simple manual or fixed riveting, this design eliminates the need to re-clamp the workpiece; simply moving the riveting head allows for quick alignment of different riveting points, greatly improving processing efficiency and automation, and is particularly suitable for multi-position or batch riveting operations.

[0039] In this embodiment, the upper support frame assembly 3 serves as the load-bearing and guiding skeleton of the device, with its core benefits lying in high stability and precise guidance. It constructs a robust top frame through the side bracket 303, providing a stable and reliable installation foundation and elevated working space for the riveting assembly. This effectively absorbs the enormous reaction force and vibration generated during riveting, ensuring a smooth processing flow. Simultaneously, the sliding engagement between its slide rail 302 and the upper slide block 201 provides high-precision linear guidance for the movement of the riveting assembly, ensuring the press maintains a vertical posture in any position, thereby guaranteeing the verticality and positional accuracy of the riveting. The rollers 3012 in the side limiting seat mechanism 301 further assist in guidance and support, reducing friction and making the movement of the riveting assembly smoother and more precise.

[0040] In a further preferred embodiment of the present invention, the side limiting component 4 includes a positioning plate 401 fixedly disposed on the base 1, a side telescopic hydraulic cylinder 402 fixedly connected to one side of the positioning plate 401, and a card seat 403 fixedly connected to one end of the side telescopic hydraulic cylinder 402.

[0041] Several arc-shaped slots are provided on one side of the card holder 403.

[0042] There are multiple side limiting components 4, and the multiple side limiting components 4 are symmetrically arranged on the outer wall of the base 1.

[0043] In this embodiment, the side limiting component 4 is used to achieve rapid, adaptive, and non-destructive clamping and fixing of the workpiece. Driven linearly by the side telescopic hydraulic cylinder 402, it can automatically center and clamp pull rods of different sizes. Its arc-shaped groove design perfectly conforms to the outer contour of the cylindrical pull rod, providing sufficient clamping force while avoiding stress concentration or scratching the workpiece surface, thus achieving flexible clamping. Multiple components are symmetrically arranged on the outside of the platform 1, applying force evenly from both sides simultaneously, ensuring the pull rod is firmly restrained at the center of the platform and aligned with the press. This effectively prevents workpiece displacement or loosening during riveting, and is crucial for ensuring accurate riveting position and operational safety.
