Description

Technical Field

[0001] This utility model belongs to the field of auxiliary tools, specifically relating to an electric linear actuator repair tool. Background Technology

[0002] Electric linear actuators, as important mechatronic components, have wide and crucial applications in numerous fields. Their key function is to convert the rotary motion of an electric motor into the linear reciprocating motion of a actuator, thus serving as a mechanical actuator in various simple or complex processes. They enable remote, centralized, or automatic control and are widely used in industries such as home appliances, kitchenware, medical devices, automobiles, heavy industrial machinery, and material handling and logistics equipment. Electric linear actuators allow for convenient adjustment of equipment position and angle, material pushing, and other functions, improving production efficiency and product quality. Furthermore, electric linear actuators offer advantages such as energy saving, environmental friendliness, and simple installation, bringing great convenience to people's production and daily lives.

[0003] However, in actual use, as the usage time increases, the limit device of the electric linear actuator is prone to failure. Under the action of external forces and other factors, the nut, lead screw, bearing and other parts of the electric linear actuator are damaged, and it is necessary to disassemble and replace the damaged parts. During on-site construction, due to the lack of machine tools, hydraulic presses and other equipment, it is difficult to manually disassemble and assemble the electric linear actuator, and there is also a safety risk of being squeezed and scratched by the construction personnel. Therefore, an auxiliary maintenance tool that can assist construction personnel in disassembling and assembling electric linear actuators is needed. Utility Model Content

[0004] The purpose of this invention is to address the problem that manual disassembly and assembly of electric linear actuators is difficult and poses safety risks such as crushing and scratching to construction workers. This invention proposes an electric linear actuator maintenance tool that can assist workers in disassembling and assembling electric linear actuators, thus ensuring the personal safety of construction workers.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: an electric actuator repair fixture, including a pressure plate, on which at least four support bolts and at least two set screws are threadedly connected. Adjusting nuts are threadedly connected to the support bolts and are located at the top of the pressure plate. In use, first, the support bolts are connected to the flange of the electric actuator itself. Then, the bottom of the set screws abuts against the spring of the electric actuator. Subsequently, the adjusting nut is rotated with a wrench, causing the adjusting nut to press down on the pressure plate. The downward pressure of the pressure plate drives the set screws to move downwards, and the set screws compress the spring, exposing the locking nut of the electric actuator itself, facilitating disassembly and assembly by the operator. This auxiliary fixture has a simple overall structure, is easy to use, and is highly practical.

[0006] Furthermore, the pressure plate is circular with a through hole in the middle, allowing it to pass through the lead screw of the electric push rod.

[0007] Furthermore, the support bolt is threaded onto the top outer side of the pressure plate, and the set screw is threaded onto the top inner side of the pressure plate. The support bolt located on the outer side is used to connect with the flange of the electric push rod itself, and the set screw located on the inner side is used to compress the spring.

[0008] Furthermore, the length of the set screw is less than the length of the support bolt.

[0009] Furthermore, the two set screws are arranged symmetrically.

[0010] Furthermore, the four support bolts are arranged in a 4×4 rectangular pattern.

[0011] As can be seen from the above technical solutions, this utility model has the following advantages:

[0012] By connecting the support bolt to the flange of the electric actuator itself, and then abutting the bottom of the set screw with the spring of the electric actuator, the adjusting nut is turned by wrench, causing the adjusting nut to press down on the pressure plate. The downward pressure of the pressure plate causes the set screw to move downward, and the set screw compresses the spring, exposing the locking nut of the electric actuator itself, so that the operator can disassemble and assemble it. This auxiliary tool has a simple overall structure, is easy to use, and is highly practical. Attached Figure Description

[0019] like Figure 1-3 As shown, this embodiment provides a maintenance fixture for an electric actuator, including a pressure plate 3. At least four support bolts 1 and at least two set screws 4 are threaded onto the pressure plate 3. The two set screws 4 are arranged symmetrically, and the four support bolts 1 are arranged in a 4×4 rectangle. Adjusting nuts 2 are threaded onto the support bolts 1, and the adjusting nuts 2 are located on the top of the pressure plate 3. The pressure plate 3 is circular with a through hole in the center. The pressure plate 3 passes through the lead screw 5 of the electric actuator through the through hole. The support bolts 1 are threaded onto the outer top of the pressure plate 3, and the set screws 4 are threaded onto the inner top of the pressure plate 3. The outer support bolts 1 facilitate connection with the electric actuator. The rod is connected to its own flange, and the spring 7 is compressed by the set screw 4 located on the inside. The length of the set screw 4 is less than the length of the support bolt 1. In use, first connect the support bolt 1 to the flange of the electric push rod itself, then abut the bottom of the set screw 4 against the spring 7 of the electric push rod. Then, turn the adjusting nut 2 with a wrench to press down the pressure plate 3. The downward pressure of the pressure plate 3 drives the set screw 4 to move downward. The set screw 4 compresses the spring 7, which exposes the locking nut 6 of the electric push rod, making it easy for workers to disassemble and assemble. This auxiliary tool has a simple overall structure, is easy to use, and is highly practical.
