Description

Technical Field

[0001] This utility model relates to the field of furniture hinge manufacturing, specifically a hinge opening and closing testing device. Background Technology

[0002] Hinges are the most common door connection components in furniture cabinets, used to open and close doors. To reduce the impact force and noise when closing doors, current furniture hinges generally incorporate a buffer mechanism. For example, Chinese patent document CN202689777U discloses a two-stage buffer hinge, and Chinese patent document CN104033064A discloses an adjustable buffer hinge; both achieve slow closing by incorporating a buffer mechanism within the hinge. Due to the large quantity of buffer hinges used, they are typically produced using automated assembly methods. However, during production, factors such as dimensional errors and installation tolerances can cause inconsistencies in the buffering time during hinge closure. Therefore, a buffering time testing process is added to the production of buffer hinges. Current testing methods primarily involve manual operation on a fixture for each individual hinge to determine the consistency of the buffering time. However, in automated production, manual testing inevitably reduces hinge production efficiency and is labor-intensive. Meanwhile, differences in testing personnel and dimensional errors in the fixtures themselves can affect the accuracy of the entire test, leading to an increase in the defect rate of hinges. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a hinge opening and closing test device with a high degree of automation and good stability.

[0004] This utility model provides a hinge opening and closing testing device, mainly including a frame, a fixed base, a conveying assembly, a hinge positioning and closing assembly, and a hinge closing and pushing assembly. The fixed base, conveying assembly, hinge positioning and closing assembly, and hinge closing and pushing assembly are all mounted on the frame. The fixed base allows hinges to be arranged sequentially; the conveying assembly is located inside the fixed base and can lift the hinges forward for transport; the hinge positioning and closing assembly and the hinge closing and pushing assembly are located at the front end of the fixed base, and are arranged sequentially along the conveying direction of the hinges.

[0005] By optimizing the above structure, the conveying assembly includes a movable seat, a lifting mechanism, and a lateral conveying mechanism. The movable seat is located inside the fixed seat and can move back and forth vertically and laterally. The lifting mechanism is located at the bottom of the movable seat to drive its vertical movement. The lateral conveying mechanism is located between the lifting mechanism and the frame to drive the movable seat's lateral movement. The lifting mechanism includes a lifting plate and a lifting cylinder, with the lifting plate fixed to the movable seat. The lifting cylinder is fixed to the lifting plate, and its piston rod is fixed to the frame. The lateral conveying mechanism includes a lateral cylinder and a conveying block, with the lateral cylinder fixed to the lifting plate, and the conveying block fixed to both the piston rod of the lateral cylinder and the movable seat.

[0006] By further improving the above structure, a guide rod is also added between the lifting plate and the frame. The guide rod is set along the direction of movement of the lifting plate to guide the lifting plate during vertical movement.

[0007] By further improving the above structure, a buffer bar is also added between the movable seat and the frame. The buffer bar is located on the frame and corresponds to the position of the movable seat to buffer the vertical movement of the movable seat.

[0008] By further improving the above structure, a slide rail is installed at the bottom of the movable seat, and a slider is installed at the top of the lifting plate. The slide rail and the slider are connected to guide the lateral movement of the movable seat.

[0009] By further improving the above structure, the frame also includes a limit block. The limit block is fixed to the frame and corresponds to the position of the conveyor block.

[0010] By optimizing the above structure, the hinge positioning and closing assembly includes a positioning frame, a first positioning cylinder, and a second positioning cylinder. The positioning frame is fixedly connected to the frame; the first positioning cylinder is located on the positioning frame and corresponds to the hinge seat position of the hinge; the second positioning cylinder is located on the positioning frame and corresponds to the hinge cup position of the hinge. The piston rod of the first positioning cylinder is equipped with a positioning block, while the piston rod of the second positioning cylinder is equipped with a closing wedge block.

[0011] By optimizing the above structure, the hinge closure actuation assembly includes an actuation cylinder and an actuation plate. The actuation cylinder is fixed to the frame, while the actuation plate is fixed to the piston rod of the actuation cylinder. The actuation plate corresponds to the hinge cup position of the hinge, enabling a single action of the actuation cylinder to test several hinges.

[0012] The beneficial effects of this hinge opening and closing testing device are as follows:

[0013] 1. The hinge opening and closing testing device of this utility model adopts a combined structure of vertical lifting and horizontal conveying to realize the step-by-step transmission of the hinge on the fixed base. First, the step-by-step transmission has the advantage of high reliability. It facilitates the stable and continuous forward transmission of the hinge after the hinge positioning and closing component and the hinge closing and pushing component complete the opening and closing test at the front end of the conveying component, greatly improving the automation level of the hinge in the opening and closing test process. Second, this utility model utilizes the combination of the hinge positioning and closing component and the hinge closing and pushing component to realize the closing triggering of a single hinge and the simultaneous testing of several hinges, thereby improving the efficiency of hinge opening and closing testing.

[0014] 2. In the hinge opening and closing testing device of this utility model, a guide rod is provided between the lifting plate and the frame, and a buffer rod is provided between the movable seat and the frame. The guide rod can guide the vertical movement of the lifting plate, avoiding misalignment or rotation of the lifting plate during movement due to the excessive length of the movable seat. The buffer rod, on the other hand, slows down and buffers the downward movement of the movable seat, improving the stability and reliability of the movable seat placing the hinge on the fixed seat.

A baffle 12 is also provided on the outer side of the fixed base 11, which is fixedly connected to the fixed base 11 to prevent the hinges from falling out of the fixed base 11 during transmission. The hinges are arranged sequentially in the same direction on the fixed base 11 so that the hinge positioning and closing assembly and the hinge closing and pushing assembly can perform a closing operation on the hinge cup of the hinge at the same side of the fixed base 11. The conveying assembly is located on the frame 1, inside the fixed base 11, and can lift the hinge and transmit it forward. The hinge positioning and closing assembly and the hinge closing and pushing assembly are also located on the frame 1, at the front end of the fixed base 11, and are arranged sequentially along the transmission direction of the hinge. During transmission, the hinge undergoes a closure test by sequentially passing through the hinge positioning and closing components and the hinge closing and pushing components, driven by the conveying component.

[0023] In one embodiment of this utility model, the conveying assembly includes a movable seat 21, a lifting mechanism, and a transverse conveying mechanism. The movable seat 21 is located inside the fixed seat 11, and the two can move relative to each other. The movable seat 21 can move back and forth vertically and laterally.

The lifting mechanism includes a lifting plate 22 and a lifting cylinder 23. The lifting plate 22 is fixed together with the movable seat 21 and provides support for it. The two ends of the lifting cylinder 23 are respectively connected to the lifting plate 22 and the frame 1. In this embodiment, the cylinder body of the lifting cylinder 23 is fixed on the lifting plate 22, and its piston rod is fixed on the frame 1. As the lifting cylinder 23 operates, its cylinder body drives the lifting plate 22 and the movable seat 21 to move back and forth vertically. The transverse conveying mechanism is located between the lifting mechanism and the frame 1 and can drive the movable seat 21 to move back and forth laterally. The transverse conveying mechanism includes a transverse cylinder 24 and a conveying block 25. The transverse cylinder 24 is located on the lifting plate 22 at the bottom of the lifting plate 22 and is fixed together with the lifting plate 22. The conveying block 25 is fixed together with the piston rod of the transverse cylinder 24 and the movable seat 21, so that the movable seat 21 can move back and forth in the transverse direction under the drive of the transverse cylinder 24.

[0024] In another embodiment, a guide rod 31 is also provided between the lifting plate 22 and the frame 1. The guide rod 31 is vertically inserted into the frame 1, and its end is fixed to the lifting plate 22 to guide the vertical movement of the lifting plate 22. In this embodiment, a guide cylinder 32 can also be provided on the frame 1. The guide cylinder 32 is fixed to the frame 1, sleeved on the outer surface of the guide rod 31, and can move relative to the guide rod 31 to further improve the guiding effect of the guide rod 31.

[0025] In another embodiment, a buffer rod is also provided between the movable seat 21 and the frame 1. The buffer rod consists of a rod body 33, a buffer cylinder 34, and a buffer element 35. One end of the rod body 33 is connected to the movable seat 21, and the other end is inserted into the buffer cylinder 34. The end of the buffer cylinder 34 away from the rod body 33 is fixed to the frame 1. The buffer element 35 is sleeved on the rod body 33, and its two ends press against the buffer cylinder 34 and the end of the rod body 33 connected to the movable seat 21, respectively, to play a vibration damping role when the movable seat 21 moves downward. In this embodiment, a guide wheel 36 is also provided between the end of the rod body 33 and the movable seat 21. The rotation shaft of the guide wheel 36 is fixed to the end of the rod body 33, and its outer circumference presses against the bottom of the movable seat 21 to play a guiding role when the movable seat 21 moves laterally.

[0026] In another embodiment, a slide rail 37 is provided at the bottom of the movable seat 21. The slide rail 37 is arranged along the direction of lateral movement of the movable seat 21 and is fixed to the movable seat 21. A slider 38 is provided at the top of the lifting plate 22. The slider 38 is also arranged along the direction of lateral movement of the movable seat 21 and is fixed to the lifting plate 22. The slider 38 and the slide rail 37 are matched and connected to make the sliding of the movable seat 21 on the lifting plate 22 smoother.

[0027] In another embodiment, a limiting block 39 is also provided on the frame 1. The limiting block 39 is fixed to the frame 1 and corresponds to the position of the conveying block 25 to position the conveying block 25 at the end of the stroke of the transverse cylinder 24. In this embodiment, the limiting block 39 can improve the stability of the transverse movement of the conveying block 25 and the movable seat 21, and avoid damage to the transverse cylinder 24 due to excessive force caused by the inertia of the movable seat 21.

[0028] In one embodiment of this utility model, the hinge positioning and closing assembly includes a positioning frame 41, a first positioning cylinder 42, a second positioning cylinder 43, a positioning block 44, and a closing wedge 45. The positioning frame 41 is mounted on and fixed to the frame 1, located at the foremost end of the fixed base 11 along the hinge conveying direction. The first positioning cylinder 42 and the second positioning cylinder 43 are both mounted on and fixedly connected to the positioning frame 41.
