Description

Technical Field

[0001] This utility model relates to the field of damper technology, and in particular to a damper resistance testing machine. Background Technology

[0002] A damper is a device that provides resistance to motion and dissipates kinetic energy. After the damper is manufactured, it needs to undergo resistance testing to check its load-bearing performance. This testing machine is a pressure testing machine used to test the resistance of dampers.

[0003] When testing dampers, a large number of samples are prepared, and multiple samples need to be tested in sequence and alternately. However, ordinary testing machines have a simple structure and can only test a single damper at a time. The damper must then be manually removed and replaced with a new one. This manual operation is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a damper resistance testing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A damper resistance testing machine includes a rectangular frame with a cavity opening penetrating the front and rear walls of the frame. A mounting base is located near the bottom of the cavity opening on the frame. A disc-shaped material tray is fixed to the upper wall of the mounting base. Four rectangular openings for placing dampers are arranged in a ring on the upper wall of the material tray. A cylinder is fixed to the top wall of the frame, and a pressure block is drivenly connected to the end of the cylinder.

[0007] Preferably, a rectangular support seat is fixedly connected at the center of the bottom wall of the machine frame near the cavity opening for contact and support with the lower wall of the material tray.

[0008] Preferably, a pair of cylindrical buckles are symmetrically distributed and fixed to the bottom end wall of the frame near the cavity opening about the center of the support seat, and the buckle seat has a cylindrical groove that is movably connected to the buckles.

[0009] Preferably, the left and right end walls of the frame are provided with side openings that communicate with the frame cavity opening.

[0010] Preferably, a rectangular assembly seat is provided near the side opening of the frame, and a seat opening for connecting a damper is passed through the center of the top of the assembly seat.

[0011] Preferably, a rectangular groove is provided at the center end wall of the bottom of the assembly seat, and a rectangular buckle that is fixed to the machine frame is engaged in the groove.

[0012] This utility model has at least the following beneficial effects:

[0013] The material tray has four equally spaced openings for mounting four dampers. During testing, four dampers can be loaded simultaneously. Under the drive of the cylinder, the pressure block moves down and presses against the upper wall of one of the dampers to test its load-bearing performance. After testing, the material tray is operated to alternate the position of the openings, switching to another damper to facilitate rapid testing of the next damper, thus increasing testing efficiency.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a damper resistance testing machine:

[0022] like Figure 1-4As shown, a damper resistance testing machine includes a rectangular frame 1. The frame 1 has a cavity 2 that penetrates the front and rear walls of the frame 1. A mounting base 5 is provided near the bottom of the frame 1 near the cavity 2. A disc-shaped material tray 7 is fixed to the upper wall of the mounting base 5. Four rectangular openings 8 for placing dampers are arranged in a ring on the upper wall of the material tray 7. A cylinder 9 is fixed to the top wall of the frame 1. A pressure block 10 is connected to the end of the cylinder 9.

[0023] A rectangular support seat 3 is fixedly connected to the center of the bottom wall of the machine frame 1 near the cavity opening 2 for contact and support with the lower wall of the material tray 7. A pair of cylindrical buckles 4 are symmetrically distributed and fixed to the bottom wall of the machine frame 1 near the cavity opening 2 about the center of the support seat 3. A cylindrical slot 6 is opened in the buckle 5 to be movably connected to the buckle 4.

[0024] The left and right end walls of the frame 1 are provided with side openings 11 that communicate with the frame cavity openings 2;

[0025] A rectangular assembly seat 12 is provided in the frame 1 near the side opening 11. The top center of the assembly seat 12 has a seat opening 15 for connecting a damper. A rectangular seat groove 13 is provided at the bottom center end wall of the assembly seat 12. A rectangular seat buckle 14 that is fixed to the frame 1 is engaged in the seat groove 13.

[0026] Working principle:

[0027] The material tray 7 has four equally spaced openings 8 for mounting four dampers. During testing, four dampers can be loaded simultaneously. During testing, the pressure block 10 moves down under the drive of the cylinder 9 and presses against the upper wall of one of the dampers to test the load resistance performance of the damper. After the test is completed, the material tray 7 is operated to alternate the position of the openings 8 to switch to another damper, so as to quickly test the next damper and improve the testing efficiency.

[0028] The buckle 4 and the slot 6 are connected to limit the position of the card seat 5 and prevent the card seat 5 from moving forward, backward, left and right. As the card seat 5 moves with the buckle 4 and the slot 6, the card seat 5 rotates and the material tray 7 rotates accordingly. This causes the pan opening 8 on the top of the material tray 7 to switch positions alternately, thereby changing the position of the four dampers installed at the four pan openings 8 respectively, quickly switching the detection material and making the detection more efficient.

[0029] The buckle 4 and the slot 6 are movably connected, allowing the card seat 5 to be removed and the entire material tray 7 to be taken off for replacement of the damper. This makes it more convenient to change materials and also makes it easier to clean the material tray 7.

[0030] At the side opening 11, the seat buckle 14 is engaged with the assembly seat 12 through the seat groove 13, which facilitates the assembly seat 12 to be disassembled and assembled. In use, the seat openings 15 of the two assembly seats 12 are respectively fitted onto the two ends of the damper. Then, the assembly seats 12 are assembled onto the frame 1. At this time, the middle part of the damper is suspended in the frame cavity opening 2 of the frame 1. At this time, the cylinder 9 runs and drives the pressure block 10 to move down, which is used to squeeze the side end wall of the damper to test the compressive and deformation resistance of the end wall of the damper.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
