Description

It can accurately and effectively prevent equipment damage caused by overload and is widely used in all mechanical transmission devices that require overload protection.

[0003] The hydraulic safety coupling is composed of a double-layer sleeve.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0015] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7As shown, an embodiment of the present invention proposes: a hydraulic coupling torque testing device, including a base plate 1, a movable support plate 2, a drive seat 3, a transmission member 5 and a dynamic torque sensor 6. The drive seat 3 rotatably connected to the fixed support plate 101 fixedly connected to the base plate 1 is transmission-connected to the drive motor 103, so that the drive motor 103 can transmit power to the drive seat 3 when it is running, so that the drive seat 3 can rotate smoothly on the fixed support plate 101, and transmit power to the coupling body 4. A plug-in rod 302 is slidably connected to the connecting seat 301 of the drive seat 3, and the plug-in rod 302 is slidably connected to the arc groove 3031 opened on the drive disk 303. The drive disk 303 is rotationally connected to the transmission The drive plate 303 is on the shaft 3011, which is convenient for rotating the driving disk 303 on the transmission shaft 3011, and the driving disk 303 is used to push the plug rod 302 to slide on the connecting seat 301, thereby completing the position debugging operation of the plug rod 302, and conveniently plugging the plug rod 302 into the bolt hole of the outer sleeve end plate of the coupling body 4 to achieve a stable connection between the coupling body 4 and the driving seat 3. The plug rod 302 is plugged into the coupling body 4, which is convenient for stably connecting the driving seat 3 to the coupling body 4, and realizing a stable connection between the two.

During the installation of the coupling body 4, the adjusting nut 506 is rotated on the adjustment screw 504 to move the adjustment screw 504, thereby pulling the connector 501 to deform, so that the deformable arc plate 5011 on the connector 501 can be tightly against the inner sleeve of the coupling body 4, so as to realize the stable connection between the transmission member 5 and the coupling body 4. The connecting sleeve 502 is rotatably connected to the movable support plate 2, which facilitates the smooth rotation of the transmission member 5 on the movable support plate 2. The transmission gear 5021 on the connecting sleeve 502 is transmission-connected to the dynamic torque sensor 6. The dynamic torque sensor 6 is fixedly connected to the movable support plate 2, which facilitates the transmission of power to the dynamic torque sensor 6 during the rotation of the transmission member 5, thereby detecting the torque data of the coupling body 4 during the power transmission process through the dynamic torque sensor 6, and smoothly completing the test operation. At the same time, the detected torque data is transmitted to the display via the data transmission line for display, or is transmitted to the background terminal at the second level for storage and display, so that the operator can process the data conveniently.

The connection between the socket 301 and the coupling body 4 is stable and effective. Both ends of the plug rod 302 extend to the outside through the adjustment slot 3012, and the drive disc 303 is rotatably connected to the transmission shaft 3011 through the ring sleeve 3032, so that the drive disc 303 can rotate smoothly on the transmission shaft 3011, thereby driving the plug rod 302 to slide smoothly on the connection seat 301 to complete the debugging operation.

The arc groove 3031 opened on the driving disk 303 is arranged in a one-to-one correspondence with the adjustment groove 3012 on the connecting seat 301, and the driving disk 303 slides against one side of the connecting seat 301, which facilitates the smooth rotation of the driving disk 303, so that it can effectively drive the plug-in rod 302 and complete the position debugging.

[0017] like Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, a connecting sleeve 5014 at one end of the connector 501 is fixedly connected to one end of the debugging screw 504, so that the connector 501 can be stably connected to the end of the debugging screw 504, so that the debugging screw 504 can pull the connector 501 to deform and tightly contact the inner sleeve of the coupling body 4, so that the two are stably connected together to ensure that power can be stably transmitted between the two. The first connecting end plate 5013 integrally arranged at the other end of the connector 501 is fixedly connected to the second connecting end plate 5023 integrally arranged at one end of the connecting sleeve 502 through the connecting bolt 503, so that the two are stably connected together to ensure stability. The connector 501 is used in combination with the connector 501, and a deformable arc plate 5011 distributed in a circular array is integrally arranged in the middle part of the connector 501. A deformation groove is arranged between two adjacent deformable arc plates 5011 to ensure that when the debugging screw 504 pulls the connector 501 to deform, the deformable arc plate 5011 can be deformed smoothly, so that it is tightly in contact with the inner sleeve of the coupling body 4, so that the two are stably connected together. A placement groove 5015 is provided on the outer wall of the deformable arc plate 5011, and an anti-skid resistance block 5012 is arranged in the placement groove 5015. The anti-skid resistance block 5012 is made of wear-resistant rubber material and can be produced together with the deformable arc plate 5011. The adaptable deformation ensures that it can stably contact the inner sleeve of the coupling body 4, so as to achieve a stable connection between the connector 501 and the coupling body 4. At the same time, the anti-skid contact block 5012 is installed in the mounting groove 5015 to avoid sliding and falling off during transmission, thereby improving the stability of the connection between the deformable arc plate 5011 and the coupling body 4. The side of the anti-skid contact block 5012 in contact with the coupling body 4 is provided with evenly distributed anti-skid convex grooves to increase the friction resistance of the contact surface, avoid relative sliding between the two, and achieve stable transmission. The first connecting end plate 5013 and the second connecting end plate 5023 are both provided with through holes for inserting the debugging screw 504, and The support frame 505 is integrally provided with support rods distributed in a circular array, and a ball 5051 is arranged on the side of the support rod in contact with the movable support plate 2. The ball 5051 is arranged in the installation groove provided on the support rod, so as to form a stable blocking support component on one side of the movable support plate 2, and provide stable and effective support for the adjusting nut 506. At the same time, the ball 5051 is used to reduce the friction between the support frame 505 and the movable support plate 2, so that the support frame 505 can rotate smoothly on one side of the movable support plate 2, ensuring that the transmission member 5 can rotate smoothly on the movable support plate 2, and the transmission power drives the dynamic torque sensor 6 to operate, and detects the torque data when the coupling body 4 rotates; The connecting sleeve 502 is rotatably connected to the movable support plate 2 through the second bearing seat 5022, ensuring that the connecting sleeve 502 can rotate smoothly on the movable support plate 2, and the transmission gear 5021 on the connecting sleeve 502 is connected to the input gear of the dynamic torque sensor 6 to ensure that the power is transmitted to the dynamic torque sensor 6 during the rotation process to realize torque data detection, and the threaded section arranged on the debugging screw 504 is matched with the threaded holes opened on the adjusting nut 506 and the anti-loosening nut 507, so that the two can be stably installed on the debugging screw 504, so that the adjusting nut 506 is used together with the support frame 505 to pull the debugging screw 504 to move, thereby causing the connector 501 to produce corresponding deformation, and during the deformation process, the deformable arc plate 5011 is tightly abutted against the inner sleeve of the coupling body 4, The present invention also provides a stable connection between the two. The adjusting nut 506 is fixedly connected with a driving frame 5061. One end of the driving frame 5061 is fixedly connected with a wrench ring, which is convenient for holding the driving frame 5061 by hand during the debugging process, thereby rotating the adjusting nut 506 on the debugging screw 504, quickly completing the position debugging operation, and improving the convenience of operation. At the same time, the driving frame 5061 may not be installed. An auxiliary wrench may be used to rotate the adjusting nut 506 on the debugging screw 504, and the debugging operation may be smoothly completed. The anti-loosening nut 507 abuts against one side of the adjusting nut 506. At the same time, after completing the position debugging of the adjusting nut 506 on the debugging screw 501, the anti-loosening nut 507 is rotated to abut against the adjusting nut 506 to prevent the adjusting nut 506 from rotating on the debugging screw 504 during subsequent operation, thereby ensuring stable operation and use. Among them, the transmission member 5 using this structure can be set to suit different sizes of the inner sleeve of the coupling body 4, and the connecting parts can be debugged according to different inner diameters, so as to achieve quick connection of different sizes, improve the scope of application and convenience of use. Compared with the technical solution of the prior art that uses rods and accessories such as bolts for connection, when detecting different inner diameters of the inner sleeves of the coupling bodies 4 of the same batch, it is necessary to replace rods of different sizes and matching accessories, which is far from being as convenient and efficient as the connector 501 at the end of the transmission member 5 using this structure. Moreover, the connector 501 can also quickly and efficiently connect coupling bodies 4 of non-standard specifications and sizes, has a wide range of applications, and is more convenient to operate.

The cooperation between the two is used to improve the stability of the sliding of the movable support plate 2 on the bottom shell 206, so as to ensure the stable and smooth completion of the position debugging operation; The driving screw 204 is rotatably connected to the bottom shell 206, so that when the servo motor 208 is driven, the driving screw 204 can rotate smoothly on the bottom shell 206 to achieve stable power output and complete position debugging. Both ends of the slide bar 205 are fixedly connected to the inner wall of the bottom shell 206 to ensure that the slide bar 205 is stably installed on the bottom shell 206, and the slide bar 205 and the sliding seat 203 can be stably used together to improve the sliding stability of the movable support plate 2.
