Description

Technical Field

[0001] The invention relates to the technical field of guide rails, and in particular to an electronic seal annular tooling guide rail. Background Art

[0002] An electric energy meter is an instrument that measures electric energy, also known as an electric meter, a fire meter, or a kilowatt-hour meter. In order to prevent people from opening the electric energy meter and modifying the inside in order to steal electricity, a sealing device is generally installed on the electric energy meter to prevent people from opening the electric energy meter without authorization.

[0003] Electronic seal is a commonly used sealing device. After the existing electronic seal completes the manufacture of hardware components, it needs to go through the key writing process, which is to write the key into the hardware with the help of special equipment. In existing production, this process is usually operated manually. During the operation, the operator needs to take the electronic seal to the device one by one to write the key. After completion, the electronic seal needs to be taken away, and then the next electronic seal is taken to the device to write the key, and the cycle continues. The shortcomings of the above operation method are: low degree of automation, time-consuming and labor-intensive, and low efficiency, and cannot meet the needs of large-scale production. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the existing electronic seal has a low degree of automation, is time-consuming and labor-intensive, and is inefficient when completing the key writing process, and cannot meet the needs of large-scale production. An electronic seal annular tooling guide rail is provided to effectively solve the above problems.

[0005] The objective of the present invention is achieved through the following technical solutions: an annular tooling guide rail for electronic seals, comprising an annular guide rail, a tooling box, a bearing seat slidably connected to the annular guide rail, and a driving device for driving the bearing seat to move along the annular guide rail; the tooling box comprises a tooling box body, a plurality of guide holes are arranged on the tooling box body, a positioning block is slidably connected in the guide hole, and a positioning hole for placing the electronic seal is arranged on the positioning block; a first piston hole is arranged on one side of the guide hole, the upper end of the second piston hole is open, a first piston is arranged in the first piston hole, and a first cavity is formed between the first piston and the lower end of the first piston hole; a cylinder body is arranged at the bottom of the guide hole, and the cylinder body A second piston is arranged in the middle, a through hole is arranged at the upper end of the cylinder body, a telescopic rod is connected to the upper end of the second piston, the telescopic rod passes through the through hole, the upper end of the telescopic rod is connected to the positioning block, a second cavity is formed between the second piston and the upper end of the cylinder body, the first cavity and the second cavity are connected by a first connecting pipe, the first cavity and the second cavity are both filled with liquid medium, and an elastic reset device is arranged between the positioning block and the bottom of the guide hole; a positioning rod corresponding to the first piston hole is arranged at the lower end of the tooling box body, and a jack matching the positioning rod is arranged on the bearing seat; a connecting groove is arranged at the lower end of the tooling box body, and an elastic buckle matching the connecting groove is arranged at the upper end of the tooling box body.

[0006] In the present invention, one end of the annular guide rail serves as the loading end, and the other end serves as the unloading end. First, the electronic seals are placed one by one in the positioning holes on the body of each tooling box. When the bearing seat moves to the loading end, the tooling box with the electronic seal is placed on the bearing seat. When placing, the positioning rod at the lower end of the tooling box body is inserted into the jack on the bearing seat to achieve positioning connection; then the tooling box will move along the annular tooling under the drive of the driving device, and will pass through the key writing device during the movement. The electronic seal on the tooling box will be written with a key through the seal writing device. After completion, the tooling box will continue to move to the unloading end of the annular guide rail. After reaching the unloading end, the entire tooling box will be removed from the bearing seat to complete unloading. The present invention can be used in conjunction with a manipulator. The process of placing the tooling box on the bearing plate and removing the tooling box from the bearing plate can be completed by the manipulator, thereby effectively improving the degree of automation of the entire process, saving time and effort, and having high operating efficiency, and can effectively meet the needs of large-scale production. In the present invention, the tool box can also be used as a storage box for storing and transporting electronic seals. When storing and transporting electronic seals, the tool box body can be stacked. When in use, the electronic seals are first placed one by one in the positioning holes on the tool box body. At this time, the upper end of the electronic seal is higher than the upper end surface of the tool box body, which makes it easy to take the electronic seal. During transportation, the tool box bodies equipped with electronic seals can be stacked and placed. When the upper tool box body is stacked on the next tool box and body, the positioning rod at the lower end of the upper tool box body will be inserted into the first piston hole on the lower tool box body, and then the upper tool box body will be pressed downward so that the lower end surface of the upper tool box body contacts the upper end surface of the lower tool box body, and the fixed connection between the two tool box bodies is achieved through the cooperation between the elastic buckle and the connecting groove; in the process of pressing the upper tool box body downward, the positioning rod on the upper tool box body will push the first piston on the lower tool box body to move downward, so that the volume of the first cavity is reduced, and the liquid medium in the first cavity enters the second cavity through the first connecting pipe. The second piston and the telescopic rod are pushed downward, thereby driving the positioning block and the electronic seal placed on the positioning block to move downward, so that the electronic seal is completely sunk into the guide hole, thereby avoiding the damage caused by the upper end of the electronic seal being exposed to the outside and being bumped; when the transportation is completed, it is only necessary to disassemble the tool box body one by one. When disassembling, it is only necessary to unfasten the elastic buckle to separate the upper and lower tool box bodies. When the two tool box bodies are separated, the positioning rod on the upper tool box body is pulled out from the first piston hole on the lower tool box body, and the positioning block will rise to the initial position under the action of the elastic reset device, so that the upper end of the electronic seal extends out of the upper end surface of the tool box body, which makes it easy to remove the electronic seal from the tool box body.

[0007] Preferably, the driving device includes two transmission wheels, one of which is connected to the motor, and the two transmission wheels are respectively arranged at two ends of the inner side of the annular guide rail, a transmission belt is connected between the two transmission wheels, and the bearing seat is connected to the transmission belt.

[0008] Preferably, the tool box body is a rectangular parallelepiped structure.

[0009] Preferably, the elastic buckle includes a connecting portion, an elastic bending portion and a hook, the elastic bending portion is in a "C" shape, the connecting portion and the hook are respectively arranged at two ends of the elastic bending portion, the connecting portion is fixedly arranged on the tool box body, and a slot matching with the hook is arranged at the top of the connecting groove; a second spring sheet is arranged between the two ends of the elastic bending portion, and the second spring sheet is in a "C" shape; a sliding hole is arranged on one side of the connecting groove, and a push rod is slidably connected in the sliding hole, one end of the push rod extends out of the outer surface of the tool box body, and a first spring is arranged between one end of the push rod extending out of the outer surface of the tool box body and the tool box body; the second spring sheet protrudes toward one side of the sliding hole. When two tool boxes are stacked, the elastic buckle on the tool box body at the bottom extends into the connecting groove on the tool box body at the top, and after the elastic buckle extends into the connecting groove, the hook cooperates with the slot at the upper end of the connecting groove, so that the upper and lower tool box bodies are fixedly connected together. When the two tooling box bodies need to be disassembled, it is only necessary to press the push rod. After being pressed, the front end of the push rod will press against the middle position of the second spring piece. After the protruding side of the second spring piece is pushed up by the push rod, on the one hand, it will directly drive the hook to move in the direction away from the slot. On the other hand, after the second spring piece is pushed up, the two ends of the second spring piece will have a tendency to open to both sides, thereby driving the two ends of the elastic bending part to open outward. Under the action of the two, the hook can effectively disengage from the slot, thereby realizing the separation of the two tooling box bodies.

[0010] Preferably, the connecting portion, the elastic bending portion and the hook are integrally formed.

[0011] Preferably, the connecting portion, the elastic bending portion and the hook are all made of plastic.

[0012] Preferably, an annular groove is provided on the inner wall of the guide hole, and an inflatable ring is provided in the annular groove; a second piston hole is horizontally provided on the inner wall of the guide hole, the second piston hole is located below the positioning block, a third piston is provided in the second piston hole, a third cavity is formed between the third piston and the bottom of the second piston hole, and the third cavity and the inflatable ring are connected by a second connecting pipe; a second spring is provided in the third cavity, and the two ends of the second spring are respectively connected to the third piston and the bottom of the second piston hole; a guide block is provided on the side of the third piston away from the second spring, the guide block is slidably connected to the second piston hole, and one end of the guide block extends out of the second piston hole; the elastic reset device includes a first rotary A movable arm and a second rotating arm, one end of the first rotating arm and one end of the second rotating arm are rotatably connected, one end of the first rotating arm away from the second rotating arm is rotatably connected to the bottom of the guide hole; one end of the second rotating arm away from the first rotating arm is rotatably connected to the bottom of the positioning block; the first rotating arm and the second rotating arm are connected to form a "V" shaped structure; a first spring sheet is connected between the first rotating arm and the second rotating arm, the first spring sheet is in a "C" shape, and the two ends of the first spring sheet are respectively connected to the first rotating arm and the second rotating arm; when the positioning block moves downward, the connection between the first rotating arm and the second rotating arm moves to contact the guide block and pushes the guide block to move toward the bottom of the second piston hole. On the one hand, the elastic reset device can play a role similar to that of a spring, generating an upward thrust on the positioning block. When the two stacked tooling box bodies are separated, the elastic reset device can push the positioning block to move upward along the guide hole to achieve the reset of the positioning block. On the other hand, when the positioning block moves downward along the guide hole and moves to the lower limit position, at this time, the positioning block moves to the bottom of the inflatable ring, the first rotating arm and the second rotating arm are bent, and the connection between the first rotating arm and the second rotating arm moves to contact the guide block and push the guide block to move toward the bottom of the second piston hole. At this time, the volume of the third cavity is reduced, and the gas in the third cavity is filled into the inflatable ring through the second connecting pipe, causing the inflatable ring to expand. After the inflatable ring expands, the electronic seal is tightened, thereby firmly fixing the electronic seal in the guide hole to prevent the electronic seal from shaking in the guide hole during transportation and being damaged.

On the one hand, the elastic reset device can play a role similar to that of a spring, generating an upward thrust on the positioning block 9. When the two stacked tooling box bodies 7 are separated, the elastic reset device can push the positioning block 9 to move upward along the guide hole 8 to achieve the reset of the positioning block 9; on the other hand, when the positioning block 9 moves downward along the guide hole 8 and moves to the lower limit position, at this time, the positioning block 9 moves to the bottom of the inflatable ring 32, the first rotating arm 24 and the second rotating arm 25 are bent, and the connection between the first rotating arm 24 and the second rotating arm 25 moves to contact with the guide block 28 and pushes the guide block 28 to move toward the bottom of the second piston hole. At this time, the volume of the third cavity 29 is reduced, and the gas in the third cavity 29 is filled into the inflatable ring 32 through the second connecting pipe 33, so that the inflatable ring 32 expands. After the inflatable ring 32 expands, the electronic seal 38 is tightened, thereby firmly fixing the electronic seal 38 in the guide hole 8 to prevent the electronic seal 38 from shaking in the guide hole 8 during transportation and being damaged.
