[0002] A double piston rod cylinder is a type of cylinder in which the piston rod extends to both ends of the cylinder simultaneously, connecting with components on both sides and driving the components on both sides to move simultaneously.

[0003] However, the existing double piston rod cylinder still has shortcomings, specifically: the existing double piston rod cylinder does not have a limit mechanism, which makes stroke control more difficult during operation. Utility Model Content

[0004] The purpose of this invention is to provide a universal double piston rod cylinder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A universal double piston rod cylinder includes a double piston rod cylinder body. An adjustment mechanism is provided on the outer wall of the cylinder body for adjusting the piston stroke. A reflective strip is fixedly connected to the outer wall of the piston rod of the cylinder body. A universal joint is fixedly connected to the top of the piston rod. A connecting sleeve is fixedly connected to the air inlet on the outer wall of the cylinder body. A gate is slidably connected inside the connecting sleeve. An electric push rod is fixedly connected to the outer wall of the gate and inside the connecting sleeve. A controller is installed on the outer wall of the cylinder body.

[0007] As a preferred embodiment of this utility model, the adjusting mechanism includes a fixed sleeve fixedly connected to the outer wall of the double piston rod cylinder body. A sliding rod is fixedly connected inside the fixed sleeve. A sliding nut is fixedly connected to the front and back of the sliding rod inside the fixed sleeve. An adjusting screw is threadedly connected inside the sliding nut. A transmission gear is fixedly connected to the outer wall of the adjusting screw near the sliding rod. A drive gear is meshed with the outer wall of the transmission gear. A servo motor is fixedly connected to the outer wall of the drive gear away from the sliding rod. A fixed plate is fixedly connected to the outer wall of the sliding rod directly above the reflective strip. A photoelectric sensor is fixedly connected inside the fixed plate. A displacement sensor is fixedly connected inside the fixed plate above the photoelectric sensor. A battery is fixedly connected inside the fixed sleeve.

[0008] As a preferred embodiment of this utility model, the universal joint, connecting sleeve, and gate are all made of aluminum alloy. The outer wall of the gate is fixedly connected with a rubber sealing ring, and two sets of gate and electric push rod are provided.

[0009] Through the above technical solution, the rubber sealing ring can prevent air from leaking from the gaps between the gates.

[0010] As a preferred embodiment of this utility model, the reflective strip is made of aluminum foil, the inner wall of the connecting sleeve is provided with a threaded connection groove above the gate, and the controller is connected to the electric push rod by electrical connection.

[0011] Through the above technical solution, the threaded connection groove can facilitate the connection of the sleeve and the air duct together.

[0012] As a preferred embodiment of this utility model, the fixed sleeve, sliding rod, and fixed plate are all made of aluminum alloy. The sliding rod passes through and extends to the outside of the fixed sleeve. The fixed plate has a T-shaped structure design. The servo motor is connected to the fixed sleeve in a fixed manner.

[0013] As a preferred embodiment of this utility model, the adjusting screw is provided in two sets, and the thread directions of the two sets of adjusting screws are opposite. A transparent protective plate is fixedly connected to the bottom of the fixing plate. The sliding rod has a hexagonal prism structure design.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, a universal double piston rod cylinder is provided. The adjustment mechanism in this device limits the stroke of the piston rod. The stroke data of the piston rod is input into the controller, which then starts the servo motor. The servo motor drives the transmission gear and the adjusting screw to rotate via the drive gear. The rotating adjusting screw drives the sliding nut to move the sliding rod outward. The sliding rod pushes the fixed plate outward. The displacement sensor detects the movement distance of the fixed plate. When the data detected by the displacement sensor matches the stroke data input into the controller, the displacement sensor inputs a signal to the controller, which then shuts off the servo motor. The servo motor no longer drives the adjusting screw to rotate, and the sliding rod and fixed plate stop moving. A conduit connects the double piston rod cylinder body to the air pump. The system starts by pumping high-pressure gas into the double-piston rod cylinder. The high-pressure gas pushes the piston rod inside the cylinder body to move outward. When the piston rod moves to the position of the fixed plate, the reflective strip on the outer wall of the piston rod aligns with the fixed plate. The reflective strip reflects the photoelectric signal emitted by the photoelectric sensor inside the fixed plate. The photoelectric sensor receives the reflected photoelectric signal and inputs a stop signal to the controller. The controller then activates the electric push rod, which pushes the gate plate inward. The inward-moving gate plate blocks the connecting sleeve, preventing high-pressure gas from entering the double-piston rod cylinder body. The piston rod of the double-piston rod cylinder body then stops moving, solving the problem that existing double-piston rod cylinders lack a limit mechanism, making stroke control difficult during operation.

An electric push rod 7 is fixedly connected to the outer wall of the gate 6 and inside the connecting sleeve 5. A controller 8 is installed on the outer wall of the double piston rod cylinder body 1.

[0026] The universal joint 4, connecting sleeve 5, and gate 6 are all made of aluminum alloy. The outer wall of the gate 6 is fixedly connected with a rubber sealing ring, which can prevent air from leaking from the gaps between the gates 6. The gate 6 and the electric push rod 7 are each equipped with two sets.

[0027] The reflective strip 3 is made of aluminum foil, and the inner wall of the connecting sleeve 5 is provided with a threaded connection groove above the gate 6. The threaded connection groove can easily connect the sleeve 5 to the air duct. The controller 8 and the electric push rod 7 are connected electrically.

[0028] In this embodiment, reference Figure 2 and Figure 3The adjustment mechanism 2 includes a fixed sleeve 201 fixedly connected to the outer wall of the double piston rod cylinder body 1. A sliding rod 202 is fixedly connected inside the fixed sleeve 201. A sliding nut 203 is fixedly connected to the front and back of the sliding rod 202 and inside the fixed sleeve 201. An adjusting screw 204 is threadedly connected inside the sliding nut 203. A transmission gear 205 is fixedly connected to the outer wall of the adjusting screw 204 and near the sliding rod 202. A drive gear 206 is meshed with the outer wall of the transmission gear 205. A servo motor 207 is fixedly connected to the outer wall of the drive gear 206 at a position away from the sliding rod 202. A fixed plate 208 is fixedly connected to the outer wall of the sliding rod 202 and directly above the reflector strip 3. A photoelectric sensor 209 is fixedly connected inside the fixed plate 208. A displacement sensor 210 is fixedly connected inside the fixed plate 208 and above the photoelectric sensor 209. A battery 211 is fixedly connected inside the fixed sleeve 201.

[0029] The fixed sleeve 201, sliding rod 202, and fixed plate 208 are all made of aluminum alloy. The sliding rod 202 passes through and extends to the outside of the fixed sleeve 201. The fixed plate 208 has a T-shaped structure design. The servo motor 207 is fixedly connected to the fixed sleeve 201.

[0030] The adjusting screw 204 is provided in two sets, and the thread directions of the two sets of adjusting screw 204 are opposite. A transparent protective plate is fixedly connected to the bottom of the fixing plate 208. The sliding rod 202 is designed with a hexagonal prism structure. The sliding nut 203 is connected to the fixing sleeve 201 by sliding connection.

[0031] The sliding rod 202 passes through and extends to the outside of the fixed sleeve 201. The adjusting screw 204 is connected to the fixed sleeve 201 by rotation. The battery 211, servo motor 207, photoelectric sensor 209 and displacement sensor 210 are all connected to the controller 8 by electrical connection.

[0032] The working process of this utility model is as follows: When using the universal double piston rod cylinder designed in this scheme, the piston rod stroke data of the cylinder body 1 is input into the controller 8. The controller 8 starts the servo motor 207. The servo motor 207 drives the transmission gear 205 and the adjusting screw 204 to rotate through the drive gear 206. The rotating adjusting screw 204 drives the sliding rod 202 to move outward through the drive sliding nut 203. The sliding rod 202 pushes the fixed plate 208 to slide outward. The displacement sensor 210 detects the movement distance of the fixed plate 208. When the data detected by the displacement sensor 210 matches the stroke data input into the controller 8, the displacement sensor 210 inputs a signal to the controller 8. The controller 8 shuts down the servo motor 207, and the servo motor 207 no longer drives the adjusting screw 204 to rotate. The sliding rod 202 and the fixed plate 208 then slide outward. When the fixed plate 208 stops moving, the connecting sleeve 5 at the top of the double piston rod cylinder body 1 is connected to the air pump using a conduit. The air pump sends high-pressure gas into the double piston rod cylinder body 1, which pushes the piston rod inside the double piston rod cylinder body 1 to move outward. When the piston rod of the double piston rod cylinder body 1 moves to the position of the fixed plate 208, the reflective strip 3 on the outer wall of the piston rod aligns with the fixed plate 208. The reflective strip 3 reflects the photoelectric signal emitted by the photoelectric sensor 209 inside the fixed plate 208. The photoelectric sensor 209 receives the reflected photoelectric signal and inputs a stop signal to the controller 8. The controller 8 starts the electric push rod 7, which pushes the gate 6 to move inward. The inward-moving gate 6 blocks the connecting sleeve 5, preventing high-pressure gas from entering the double piston rod cylinder body 1, and the piston rod of the double piston rod cylinder body 1 stops moving.

Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the electric actuator 7, controller 8, servo motor 207, photoelectric sensor 209, and displacement sensor 210 will not be described in detail here.
