[0021] The clamping mechanism 8 includes a first guide rail 801, a first electric push rod 802, a cylinder 803, a second guide rail 804, a second electric push rod 805, a first slide 806, a stop plate 807, a second slide 808, a first clamping plate 809, a second clamping plate 810, a first anti-wear plastic plate 811 and a second anti-wear plastic plate 812.

One side of the surface of the connecting plate 7 is connected to the second electric push rod 805, the surface of the first guide rail 801 is connected to the first slide 806, one end of the cylinder 803 is connected to the plate 807, one end of the second guide rail 804 is connected to the second slide 808, the surface of the first slide 806 is connected to the first clamping plate 809, the surface of the second slide 808 is connected to the second clamping plate 810, one side of the surface of the first clamping plate 809 is connected to the first anti-wear plastic plate 811, and one side of the surface of the second clamping plate 810 is connected to the second anti-wear plastic plate 812. When holding, first place the cylinder on the surface of the first clamping plate 809, then start the first electric push rod 802, then one end of the first electric push rod 802 extends out and pushes the first slide 806 to move along the first guide rail 801, then the first slide 806 drives the two groups of first clamping plates 809 and the first anti-wear plastic plate 811 to move towards each other and clamp the cylinder, and one side of the first clamping plate 809 and the first anti-wear plastic plate 811 is slightly curved, at this time the cylinder moves up and is clamped to the center of the first clamping plate 809 and the first anti-wear plastic plate 811, and at the same time the piston sleeve is placed on the second clamping plate 8 10, and then start the second electric push rod 805, one end of the second electric push rod 805 extends out and pushes the second slide 808 to move along the second guide rail 804, and then the second slide 808 drives the two sets of second clamping plates 810 and the second anti-wear plastic plates 812 to move toward each other and clamp the piston rod, and one side of the second clamping plate 810 and the second anti-wear plastic plate 812 has a slight arc, at this time the piston rod moves up and is clamped to the center of the second clamping plate 810 and the second anti-wear plastic plate 812, and then the cylinder 803 drives the abutment plate 807 to move and abut one end of the piston rod.

[0022] Furthermore, one side of the surface of the first anti-wear plastic plate 811 is in contact with the first clamping plate 809, and two groups of first clamping plates 809 are provided. Through the setting of the first anti-wear plastic plate 811, when in use, the first anti-wear plastic plate 811 can prevent the first clamping plate 809 from directly contacting the cylinder and causing wear, thereby protecting the surface of the cylinder and increasing the friction between the cylinder to ensure firm clamping and prevent the cylinder from sliding or shifting during assembly.

[0023] Further, one side of the surface of the second anti-wear plastic plate 812 is fitted with the second clamping plate 810. There are two groups of the second clamping plates 810. Through the setting of the second anti-wear plastic plate 812, during use, the second anti-wear plastic plate 812 can prevent the second clamping plate 810 from directly contacting the piston rod and causing wear, protect the surface of the piston rod, and at the same time increase the friction force with the piston rod to ensure firm and reliable clamping of the piston rod.

[0024] Further, one end of the cylinder 803 penetrates through the support plate 6 and is connected to the abutting plate 807. There are two groups of the first guide rails 801. Through the setting of the first guide rails 801 and the cylinder 803, during use, the first guide rails 801 can provide a stable moving track for the first sliding plate 806, ensure that the first sliding plate 806 can accurately move in a specific direction under the push of the first electric push rod 802, so as to drive the first clamping plate 809 and the first anti-wear plastic plate 811 to clamp and position the cylinder barrel. The cylinder 803 can provide power for the abutting plate 807, so that the abutting plate 807 can quickly move and abut against one end of the piston rod when needed, playing a key role in fixing the position of the piston rod during the assembly process.

[0025] Further, the moving mechanism 2 includes a motor 201, a stabilizing rod 202 and a threaded rod 203. The motor 201 is installed on one side of the surface of the base 1, the stabilizing rod 202 is connected to the inside of the base 1, and one end of the motor 201 is connected to the threaded rod 203. Through the setting of the motor 201, the stabilizing rod 202 and the threaded rod 203, during use, after the cylinder barrel and the piston rod are respectively clamped and fixed by the clamping mechanism 8, first start the motor 201, then the motor 201 drives the threaded rod 203 to rotate, and then the threaded rod 203 drives the first sliding seat 3 and the second sliding seat 4 to move along one end of the stabilizing rod 202. After that, the second sliding seat 4 drives the piston rod to move until one end of the piston rod is inserted into the cylinder barrel. At this time, one end of the piston rod is successfully installed into the cylinder barrel.

[0026] Further, one end of the motor 201 penetrates through the base 1 and is connected to the threaded rod 203. One end of the threaded rod 203 is connected to the first sliding seat 3 through penetration, and one end of the threaded rod 203 is connected to the second sliding seat 4 through penetration. Through the setting of the threaded rod 203, during use, the threaded rod 203 can rotate under the drive of the motor 201 and drive the first sliding seat 3 and the second sliding seat 4 to move through screw drive. The threaded structure of the threaded rod 203 can convert the rotational motion of the motor 201 into a linear motion, realizing precise displacement control of the piston rod, so that the piston rod can smoothly approach the cylinder barrel and be inserted into it.

[0027] Further, one end of the stabilizer bar 202 is connected through the first sliding seat 3, and one end of the stabilizer bar 202 is connected through the second sliding seat 4. By providing the stabilizer bar 202, during use, the stabilizer bar 202 mainly plays a role in stabilizing and guiding. The first sliding seat 3 and the second sliding seat 4 slide along the stabilizer bar 202 during movement, ensuring the linearity and stability of the movement, preventing deviation or shaking, and thus ensuring that the piston rod can be accurately aligned with and inserted into the cylinder barrel.

[0028] Working principle: First, when clamping the cylinder barrel and the piston rod, first place the cylinder barrel on the surface of the first clamping plate 809, then start the first electric push rod 802. Then, one end of the first electric push rod 802 extends and pushes the first sliding plate 806 to move along the first guide rail 801. Subsequently, the first sliding plate 806 drives the two groups of first clamping plates 809 and the first anti-wear plastic plate 811 to move towards each other and clamp the cylinder barrel. The first clamping plate 809 and the first anti-wear plastic plate 811 have a slight arc on one side. At this time, the cylinder barrel will move upward and be clamped to the central part of the first clamping plate 809 and the first anti-wear plastic plate 811. At the same time, place the piston sleeve in the middle of the second clamping plate 810, then start the second electric push rod 805. One end of the second electric push rod 805 extends and pushes the second sliding plate 808 to move along the second guide rail 804. Subsequently, the second sliding plate 808 drives the two groups of second clamping plates 810 and the second anti-wear plastic plate 812 to move towards each other and clamp the piston rod. The second clamping plate 810 and the second anti-wear plastic plate 812 have a slight arc on one side. At this time, the piston rod will move upward and be clamped to the central part of the second clamping plate 810 and the second anti-wear plastic plate 812. Then, the cylinder 803 drives the abutting plate 807 to move and abut against one end of the piston rod. After that, after the cylinder barrel and the piston rod are respectively clamped and fixed by the clamping mechanism 8, first start the motor 201, then the motor 201 drives the threaded rod 203 to rotate. Subsequently, the threaded rod 203 drives the first sliding seat 3 and the second sliding seat 4 to move along one end of the stabilizer bar 202. Then, the second sliding seat 4 drives the piston rod to move until one end of the piston rod is inserted into the cylinder barrel. At this time, one end of the piston rod is successfully installed into the cylinder barrel.
