Description

Technical Field

[0001] The utility model relates to the technical field of equipment structure testing, in particular to a steam oven hinge testing table. Background Art

[0002] As a tool for making various delicacies, steam ovens are widely used in daily life. During use, operators need to repeatedly open and close the door. After processing and manufacturing, the performance and life of the steam ovens usually need to be tested. For example, a Chinese utility model patent with patent number CN202221951707.7 (publication number CN218271339U) "An oven door hinge life tester" discloses such a tester, which is provided with a first test station and a second test station in parallel. The clamping mechanism on the top is used to fix the oven. The test bench is provided with a side-turning manipulator on each of the two stations, which can reciprocate and open the oven door located at the corresponding station. The number of openings and closings represents the service life of the hinge. The two stations can be used one by one or at the same time.

[0003] However, the tester only considers the life of the oven door hinges, but does not consider that the hinges will affect the opening and closing force of the oven door during use. Too much or too little opening and closing force will lead to a poor user experience. Therefore, further improvements need to be made to the hinge test of the steam oven. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a steam oven hinge test bench capable of testing the opening and closing forces in view of the above-mentioned existing technical status.

The counterweight block has a certain weight, which is close to the weight of the door of the actual steam oven; at the same time, the height of the counterweight block is designed to be close to the height of the actual door, which can realize the true restoration of the actual door opening action of the user.

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 5 As shown, it is a best embodiment of the utility model. The steam oven hinge test bench includes a test platform and a test door 1 vertically arranged on the test platform along the Y direction, the test door 1 is used to simulate the door body of the steam oven to be tested, the test platform is also provided with a power force member for providing the test door 1 to move along the front-back direction X simulating the user's pulling, and a hinge assembly 2 is arranged on the opposite side of the force member with the test door 1 as the boundary, the lower part of the test door 1 is hinged thereon through a pin shaft 21, and the upper part of the test door 1 is connected to a handle 11, the handle 11 is used to simulate the handle of the steam oven, and also includes a transmission mechanism 3 that cooperates with the force member to transmit, the two cooperate to simulate the opening and closing action of the test door 1 being opened, the handle 11 is hinged on the transmission mechanism 3 through an axis parallel to the pin shaft 21, and a tension test device is arranged between the transmission mechanism 3 and the handle 11. Among them, the force-applying member can be a motor 8, a cylinder or manual, etc. For the convenience of arrangement, the preferred force-applying member in this embodiment is a motor 8, which is arranged on the test platform, and the output end of the motor 8 is connected to the transmission mechanism 3.

[0030] During the tensile test of the test door 1, a component is required to simulate the opening and closing action of a user. The component not only needs to provide a backward force in the X direction, but also needs to be connected to the handle 11 of the test door 1, thereby driving the test door 1 to move together. The transmission mechanism 3 in this embodiment includes a first transmission member 31, and the cross section of the first transmission member 31 is "L" shaped (refer to Figures 1 to 3), including a transverse portion 311 arranged on the first guide rail 4 extending forward and backward along the X direction, and a vertical portion 312 arranged perpendicularly on the transverse portion 311. The transverse portion 311 is arranged on the first guide rail 4, wherein the transverse portion 311 can select a variety of ways to realize transmission, for example, a roller is arranged at the bottom of the transverse portion 311, and the roller moves linearly in the first guide rail 4 under the drive of the force-applying member. In order to simplify the installation steps, in this embodiment, it is preferred to arrange a support foot 3111 below the transverse portion 311, and a groove matching the first guide rail 4 is arranged on the bottom surface of the support foot 3111. Under the drive of the force-applying member, the transmission mechanism 3 can move along the X direction on the first guide rail 4 as a whole; the vertical portion 312 is connected to the handle 11, and at this time, the test door 1 and the transmission mechanism 3 maintain linkage.

[0031] When the user pulls the door of the steam oven, the direction of the pulling force is always perpendicular to the door, and the transmission mechanism 3 can only move along the X direction under the drive of the force-applying member, that is, the pulling force provided is always maintained in the X direction. In order to achieve a more realistic simulation effect, reference Figure 1 In this embodiment, the vertical portion 312 is provided with a second guide rail 5 extending in the Y direction, and the Y direction of the second guide rail 5 is parallel to the central axis C direction of the door body of the steam oven to be tested. The second guide rail 5 is provided with a second transmission member 32, and a second transmission member 32 for changing the pulling force direction is also provided. The second transmission member 32 makes a linear motion in the Y direction on the second guide rail 5. The second transmission member 32 is equivalent to an adapter, which can convert the pulling force of the first transmission member 31 in the X direction into a force perpendicular to the test door 1, thereby simulating the opening and closing action of the user pulling the handle by hand. At the same time, in order to make the test door 1 closer to the door body of the steam oven, the test door 1 also includes a counterweight block 12 that simulates the height and weight of the door body. The counterweight block 12 has a certain weight, and its weight is close to the weight of the door body of the actual steam oven; at the same time, the height of the counterweight block 12 is designed to be close to the height of the actual door body, which can realize the true restoration of the actual door opening action of the user.

[0032] In order to more intuitively reflect the tension on the test door 1 during the test, it is necessary to select a corresponding device to test the tension. There are many options for testing the tension. In order to facilitate layout and save costs, refer to Figure 1 and Figure 3 In this embodiment, the preferred device for testing tension is a digital tension gauge 6, one end of the digital tension gauge 6 is provided with a first connecting member 61 connected to the end of the second transmission member 32, and the other end of the digital tension gauge 6 is provided with a second connecting member 62 connected to the handle 11. The tension of the transmission mechanism 3 pulling the test door 1 can be tested by the digital tension gauge 6, and the test data can be intuitively displayed on the digital tension gauge 6, and the test can be completed by directly reading and recording the data.

[0033] The test door 1 rotates around the hinge axis during the opening and closing process, and the opening and closing movement has an impact on the life of the hinge assembly 2. The hinge assembly 2 in this embodiment includes a support arm 22, and a slider 24 is arranged in the support arm 22. The support arm 22 is provided with a third guide rail 7 for the slider 24 to slide along the X direction under the rotation force of the test door 1. The test door 1 rotates under the action of the force member. The slider 24 inside the third guide rail 7 can make the opening action of the test door 1 smoother, thereby reducing damage to the hinge assembly 2. The hinge assembly 2 also includes an elastic member 23 (refer to Figure 5 ), the elastic member 23 abuts against one end of the slider 24 close to the hinge, so that the slider 24 always drives the test door 1 to return to a vertical position with respect to the test platform direction Y. When the test door 1 is opened by the force member, when the force member stops applying force, the spring drives the test door 1 to reset under the action of the rebound force.

[0034] The specific working steps of the steam oven hinge test bench are as follows: turn on the power switch of the motor 8. Driven by the motor 8, the first transmission member 31 moves backward along the X direction on the first guide rail 4. At this time, the second transmission member 32 pulls the handle 11 through the digital display dynamometer 6, thereby driving the test door 1 to rotate along the hinge axis. As the first transmission member 31 continues to move backward, the second transmission member 32 on the second guide rail 5 continues to transmit downward along the Y direction. At this time, the tension always remains perpendicular to the test door 1, thereby simulating the process of the user pulling the door body of the steam oven. When the test door 1 is pulled to the extreme position, read and record the data on the digital display dynamometer 6 to complete the test process. Repeat the above steps many times, record multiple sets of test data, and calculate the average value. After the test is completed, adjust the hinge accordingly according to the test data, so that the tension of the steam oven hinge can meet the needs of the user.
