Description

Technical Field

[0001] This utility model belongs to the field of testing machines, and relates to trailer bar testing, and more particularly to a three-degree-of-freedom trailer bar comprehensive testing machine. Background Technology

[0002] Application CN202210745576.5 discloses a three-degree-of-freedom coordinated loading test bench for articulated devices, including a loading actuator, a gantry, and a worktable. The gantry is mounted on the worktable; a vertical loading actuator is connected to the top of the vertical loading beam; the vertical loading actuator is connected to one end of the articulated specimen via a vertical loading connecting plate. However, when positioning the specimen, three servo actuators surround it, making it easy for other components to obstruct the installation. Furthermore, while articulated connections are commonly used in shock absorber testing, trailer booms are not suitable for articulated connections; therefore, this application does not facilitate the positioning of trailer booms. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a three-degree-of-freedom trailer boom integrated testing machine.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a three-degree-of-freedom trailer boom integrated testing machine, including a gantry frame, a vertical servo actuator, a longitudinal servo actuator, a transverse servo actuator, and a base mounted on the gantry frame, and also including a slide table. The slide table and the transverse servo actuator are respectively arranged on both sides of the gantry frame. Several longitudinal grooves are provided on the upper side of the slide table, and steel rollers are arranged in the longitudinal grooves. A mounting seat is provided above the steel rollers. A hydraulic cylinder is hinged to the side of the mounting seat away from the transverse servo actuator. A mounting plate is connected to the side of the mounting seat near the transverse servo actuator. Several longitudinal strip holes are provided on the mounting plate.

[0005] Preferably, the mounting base has slots on both sides, and a first support frame is fixed on the base. The first support frame is connected to a plug for inserting into the slot, and the plug has an inverted F-shaped cross-section.

[0006] Preferably, the steel roller is provided with limit frames at both ends.

[0007] Preferably, rollers are also connected to both sides of the mounting base, and the upper side of the rollers is slidably connected to the limiting frame.

[0008] Preferably, the hydraulic cylinder is also connected to a rotating frame, and a second support frame is rotatably connected to both ends of the rotating frame.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] This utility model installs a trailer bar on a mounting base and is equipped with a hydraulic cylinder to pull the mounting base to move. When installing the trailer bar, the hydraulic cylinder pulls the mounting base away from the gantry and other components, so that there is enough space for workers to carry out the installation work. After the installation is completed, the hydraulic cylinder pushes the mounting base back to its original position.

[0011] This utility model is provided with a plug for inserting into the slot. The plug is fixed by the first support frame, so that the mounting base remains stable when performing force loading tests in all directions. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] like Figures 1-5 As shown, the three-degree-of-freedom trailer boom integrated testing machine includes a gantry frame 1, a vertical servo actuator 2, a longitudinal servo actuator 3, a transverse servo actuator 4, and a base 5, all mounted on the gantry frame 1. The vertical servo actuator 2, the longitudinal servo actuator 3, and the transverse servo actuator 4 are used to apply vertical, horizontal longitudinal, and horizontal transverse loads to the specimen.

[0022] To facilitate installation, this utility model also includes a slide table 7. The slide table 7 and the transverse servo actuator 4 are respectively arranged on both sides of the gantry frame 1. The upper side of the slide table 7 is provided with several longitudinal grooves. A steel roller 71 is arranged in the longitudinal grooves. The steel roller 71 can rotate in the longitudinal grooves. A mounting seat 6 is arranged above the steel roller 71. The mounting seat 6 can slide on the steel roller 71. A hydraulic cylinder 8 is hinged to the side of the mounting seat 6 away from the transverse servo actuator 4.

[0023] Usage: Before installing the test piece, start the hydraulic cylinder 8 to pull the mounting base 6 to move it away from the vertical servo actuator 2, the longitudinal servo actuator 3, and the horizontal servo actuator. After installation, the hydraulic cylinder 8 will push the mounting base 6 back to its original position.

[0024] To facilitate the installation of specially shaped test pieces—trailer booms, this utility model has a mounting plate 61 connected to the side of the mounting base 6 near the lateral servo actuator 4, and the mounting plate 61 is provided with a number of longitudinal strip holes 611.

[0025] Installation method: The trailer bar is bolted to the mounting plate 61. The trailer bar is connected below the mounting plate 61, and the mounting plate 61 can accommodate trailer bars of different lengths.

[0026] Furthermore, slots 62 are provided on both sides of the mounting base 6, and a first support frame 9 is fixed on the base 5. The first support frame 9 is connected to a plug 91 for inserting into the slot 62. The plug 91 has an inverted F-shaped cross section. Before installing the test piece, the hydraulic cylinder 8 pulls the mounting base 6 away from the plug 91. After the test piece is installed, the hydraulic cylinder 8 pushes the mounting base 6 back to its original position, which also allows the plug 91 to re-insert into the slot 62, thus enhancing the stability of the mounting base 6 during the test.

[0027] Furthermore, limit frames 10 are provided at both ends of the steel roller 71 to prevent the steel roller 71 from moving longitudinally.

[0028] Furthermore, rollers 63 are connected to both sides of the mounting base 6, and the upper side of the rollers 63 is slidably connected to the limit frame 10, which further enhances the stability of the mounting base 6 when it moves.

[0029] Furthermore, the hydraulic cylinder 8 is also connected to a rotating frame 81, and the two ends of the rotating frame 81 are rotatably connected to a second support frame 82.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
