Description

Technical Field

[0001] This utility model relates to the field of medical cable tray testing technology, and more specifically, to a cable tray repeated removal and wearing testing device. Background Technology

[0002] In the medical fields of dental implantology and prosthetics, dental bridges, as key components connecting implants and prostheses, directly impact clinical outcomes due to their mechanical stability and wear resistance. Existing dental bridge testing devices generally suffer from the following shortcomings:

[0003] Traditional devices often use single-point or double-point clamping, which makes it difficult to ensure uniform force on the cable tray during testing, and can easily lead to deformation of the clamping parts or deviation of test data.

[0004] Some devices can only roughly control the lifting speed and cannot accurately monitor the dynamic force changes during the removal and wearing process in real time, making it difficult to quantitatively assess the mechanical performance degradation of the cable tray.

[0005] The lack of intuitive wear monitoring tools necessitates the manual disassembly of samples periodically for visual inspection, which makes it impossible to dynamically record the wear process, affecting testing efficiency and data integrity.

[0006] Relying on manual operation to complete the insertion and removal cycle results in low testing efficiency and makes it difficult to simulate complex clinical stress scenarios (such as vertical and tilted insertion and removal).

[0007] To address the aforementioned issues, this utility model provides a cable tray repeated removal and wearing test device, which improves the accuracy and reliability of the test through multi-point clamping, dual pressure sensor monitoring, automated lifting mechanism, and visual wear recording. Utility Model Content

[0008] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cable tray repeated removal and wearing test device to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a device for repeatedly removing and putting on a cable tray, comprising a base plate, a bracket mounted on the base plate, a lifting mechanism mounted on the bracket, a guide plate mounted at the bottom of the lifting mechanism, a second pressure sensor mounted on the guide plate, a first pressure sensor mounted on the lifting mechanism, a force measuring component slidably connected to the guide plate between the first and second pressure sensors, multiple sets of clamping components mounted at the bottom of the force measuring component, a platform mounted on the base plate, and an implant shoulder mounted on the platform.

[0010] Preferably, the lifting mechanism includes a first electric push rod, a lifting plate, and a bolt rod. The first electric push rod is mounted on a bracket, the lifting plate is mounted on the telescopic end of the first electric push rod, and the bolt rod is mounted on the bottom end of the lifting plate. The bolt rod is connected to a guide plate.

[0011] Preferably, the guide plate has multiple guide holes, and the force measuring component is slidably connected to each guide hole.

[0012] Preferably, the force measuring assembly includes a carrier plate, guide rods, a fixed plate, a first pressure block, and a second pressure block. Multiple sets of clamping assemblies are installed at the bottom of the carrier plate, and multiple guide rods that are slidably connected to guide holes are provided at the top of the carrier plate. The multiple guide rods are connected to the fixed plate. A first pressure block that fits against the first pressure sensor is welded to the top of the fixed plate, and a second pressure block that fits against the second pressure sensor is welded to the bottom of the fixed plate.

[0013] Preferably, the clamping assembly is provided in three sets, with two clamping assemblies in each set. Two sets of clamping assemblies are used to clamp the inner and outer ends of the cable tray, and the other set of clamping assemblies is used to clamp the inner and outer parts of the middle of the cable tray.

[0014] Preferably, the clamping assembly includes a second electric actuator and a clamping plate, wherein the second electric actuator is mounted below the carrier plate, and the clamping plate is mounted on the telescopic end of the second electric actuator.

[0015] In practice, the second electric actuator of each group extends, causing each clamping plate to squeeze the cable tray, thereby clamping and fixing the cable tray to prevent loosening during testing.

[0016] Preferably, a camera is mounted on a platform below the middle of the implant shoulder.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. By setting up a first pressure sensor and a second pressure sensor, the supporting force when the cable tray is "put on" and the frictional force when it is "removed" can be monitored in real time. Combined with the changes in pressure values, the degree of wear of the cable tray can be accurately determined. In addition, the camera under the implant shoulder can intuitively record the wear details of the cable tray surface, providing a visual basis for data analysis.

[0019] 2. The clamping assembly is set with three sets of six clamping plates in total. Two sets clamp the inner and outer sides of both ends of the cable tray, and one set clamps the inner and outer sides of the middle part, so as to achieve uniform fixation of the cable tray at multiple points and avoid errors or sample loosening caused by unstable clamping during the test.

[0020] 3. The lifting mechanism is driven by the first electric actuator, which can automatically control the lifting path of the cable tray. With the guide hole of the guide plate and the guide rod of the force measuring component, stable reciprocating motion can be achieved. Multiple repeated removal and wearing tests can be completed without manual intervention, thus improving testing efficiency.

[0021] 4. The guide plate and force measuring component are slidably connected to the guide rod through the guide hole to ensure accurate motion trajectory during lifting and lowering, reduce lateral swaying, and improve the reliability of test results. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] As attached Figure 1-4The device shown is a test device for repeated removal and insertion of a bridge tray, comprising a base plate 1, a bracket 2 mounted on the base plate 1, a lifting mechanism 3 mounted on the bracket 2, a guide plate 4 mounted at the bottom of the lifting mechanism 3, a second pressure sensor 10 mounted on the guide plate 4, a first pressure sensor 9 mounted on the lifting mechanism 3, a force measuring component 5 slidably connected to the guide plate 4 between the first pressure sensor 9 and the second pressure sensor 10, a plurality of clamping components 6 mounted at the bottom of the force measuring component 5, a platform 7 mounted on the base plate 1, and an implant shoulder platform 8 mounted on the platform 7.

[0029] In practice, multiple clamping components 6 clamp the cable tray together. Then, the lifting mechanism 3 operates to lower the clamped cable tray and place it onto the implant shoulder 8. During the "wearing" process, the cable tray is supported by the implant shoulder 8, causing the force measuring component 5 to rise and press against the first pressure sensor 9. Based on the pressure setting during "wearing", when the pressure value detected by the first pressure sensor 9 reaches the set pressure value, the lifting mechanism 3 stops descending and then rises again to simulate the "removal" action. During the "removal" process, the friction between the cable tray and the implant shoulder 8 causes the force measuring component 5 to press against the second pressure sensor 10, allowing the second pressure sensor 10 to detect the force when "removing" the cable tray. This process is repeated to perform repeated wearing and removal tests. By detecting the change in force during each "removal" by the second pressure sensor 10, it is determined whether the cable tray has been worn. After a certain number of tests, the tester can visually inspect the wear of the cable tray.

[0030] The lifting mechanism 3 includes a first electric push rod 301, a lifting plate 302, and a bolt rod 303. The first electric push rod 301 is mounted on the bracket 2. The lifting plate 302 is installed at the telescopic end of the first electric push rod 301. The bolt rod 303 is installed at the bottom end of the lifting plate 302 and is connected to the guide plate 4.

[0031] In practice, by extending and retracting the first electric push rod 301, the bolt rod 303 at the bottom of the lifting plate 302 can drive the guide plate 4 to rise and fall, thereby causing the force measuring component 5 to rise and fall accordingly. This allows the cable tray, which is held by multiple clamping components 6, to rise and fall, thus enabling the removal and wearing test.

[0032] The guide plate 4 has multiple guide holes, and the force measuring component 5 is slidably connected to each guide hole.

[0033] The force measuring component 5 includes a carrier plate 501, guide rods 502, a fixing plate 503, a first pressure block 504, and a second pressure block 505. Multiple sets of clamping components 6 are installed at the bottom of the carrier plate 501. Multiple guide rods 502 that are slidably connected to guide holes are provided at the top of the carrier plate 501. Multiple guide rods 502 are connected to the fixing plate 503. A first pressure block 504 that fits against the first pressure sensor 9 is welded to the top of the fixing plate 503. A second pressure block 505 that fits against the second pressure sensor 10 is welded to the bottom of the fixing plate 503.

[0034] In specific implementation, when the carrier plate 501 is supported by the cable tray sleeve on the implant shoulder 8, the guide rods 502 support the fixing plate 503 to rise under the guidance of the guide holes, thereby causing the first pressure block 504 to squeeze the first pressure sensor 9, thus controlling the pressure of the cable tray on the implant shoulder 8. When the carrier plate 501 is subjected to the frictional force generated by the separation of the cable tray and the implant shoulder 8, the fixing plate 503 can be lowered, thereby causing the second pressure block 505 to squeeze the second pressure sensor 10, thus detecting the frictional force generated each time the cable tray is removed, and thus detecting the wear degree of the cable tray based on the force change detected by the second pressure sensor 10.

[0035] The clamping components 6 are provided in three sets, with two clamping components in each set. Two sets of clamping components 6 are used to clamp the inner and outer ends of the cable tray, and the other set of clamping components 6 is used to clamp the inner and outer parts of the middle of the cable tray.

[0036] The clamping assembly 6 includes a second electric push rod 601 and a clamping plate 602. The second electric push rod 601 is installed below the carrier plate 501, and the clamping plate 602 is installed at the telescopic end of the second electric push rod 601.

[0037] In practice, the second electric push rod 601 of each group extends, causing each clamping plate 602 to squeeze the cable tray, thereby clamping and fixing the cable tray and preventing it from loosening during testing.

[0038] A camera is mounted on the platform 7 located below the middle of the implant shoulder 8.

[0039] In practice, a camera can be used to inspect the bottom surface of the cable tray each time it is removed or put on, thereby recording the surface changes of the cable tray after each removal or put on, which can determine the degree of wear and facilitate subsequent analysis of the wear resistance of the cable tray.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
