The installation tool comprises: a base 1, a first positioning pin 2, a telescopic component 3, a lower template 4, an upper template 5, a locking head 6, and a first adsorption component 44.

[0043] Among them, the base 1 has a bottom surface and a supporting surface; one end of the first positioning pin 2 is fixedly connected to the base 1, and the axial direction of the first positioning pin 2 is perpendicular to the supporting surface of the base 1; the telescopic direction of the telescopic component 3 is perpendicular to the supporting surface of the base 1, and the telescopic component 3 is slidably connected to the base 1, and the telescopic end of the telescopic component 3 can be moved in the vertical direction relative to the supporting surface of the base 1 to be ejected and retracted; the lower template 4 has a first through hole 41 and a plurality of second through holes 42, the guide of the first through hole 41, the guide of the second through hole 42 and the normal direction of the supporting surface of the lower template 4 are parallel, and the lower template 4 is connected to the first positioning pin 2 away from the end of the base 1 through the first through hole 41 The second through hole 42 is used to cooperate with the fixing nut of the damping structure 71 in the piston assembly 7; the upper template 5 is arranged opposite to the lower template 4, and the structure of the upper template 5 is symmetrical with the structure of the lower template 4. The upper template 5 and the lower template 4 are respectively used to cooperate with the upper surface and lower surface of the piston assembly 7; one end of the locking head 6 has an assembly groove 61, and the assembly groove 61 is used to embed the end of the damping structure 71 away from the fixing nut, and the other end of the locking head 6 is used to apply torque; the inner wall of each second through hole 42 is provided with a first adsorption component 44, and the first adsorption component 44 is used to adsorb and position the other end of the damping structure 71.

[0044] When implementing it specifically, Figure 1As shown, first, the fixing nut and the damping nut in the piston assembly 7 are placed on the second through-hole positions of the upper template 5 and the lower template 4, wherein the damping nut and the fixing nut are placed in the second through-hole 42, and the positioning of the fixing nut and the damping nut is completed by the first adsorption component 44 on the inner wall of the second through-hole 42. Then, the damping structure 71 and other accessories in the piston assembly 7 are assembled (the fixing nut and other structures are in an assembled connection but not tightened state), and then the end of the damping structure 71 away from the fixing nut is passed through the upper template 5 and matched with the assembly groove 61 on the locking head 6. 4, and then the piston assembly 7, the upper template 5 and the lower template 4 are positioned and assembled so that the piston assembly 7 is located between the upper template 5 and the lower template 4. At this time, the first through hole 41 of the lower template 4 is plugged into the first positioning pin 2 and installed on the surface of the base 1. The lower template 4 is rotated to adjust the placement of the lower template 4 on the base 1. When it is rotated to the appropriate position, the telescopic component 3 is pushed to move so that the telescopic end of the telescopic component 3 moves in the vertical direction to eject the supporting surface of the base 1 and extend into the second through hole 42 of the lower template 4 to complete the positioning of the lower template 4. At this time, the operator only needs to The other end of the locking head 6 needs to be rotated by a device that provides torque to complete the locking work of one set of damping structures 71; when it is necessary to lock multiple sets of damping structures 71 with opposite installation directions, it is only necessary to loosen the telescopic component 3 so that the telescopic end of the telescopic component 3 moves and retracts into the supporting surface of the base 1. The telescopic component 3 no longer provides positioning for the lower template 4, and then the assembly structure of the lower template 4, the piston assembly 7 and the upper template 5 is turned over. Since the structures of the upper template 5 and the lower template 4 are symmetrical, the first through hole 41 of the upper template 5 can be aligned with the first through hole 41 of the lower template 4. After the positioning pin 2 is plugged in and installed, the above operations are repeated to complete the positioning of the upper template 5, and the above steps are continued to be repeated to complete the locking work of multiple groups of damping structures 71 with opposite installation directions in the piston assembly 7; when the locking work of all the damping structures 71 is completed, the telescopic component 3 is released so that the telescopic end of the telescopic component 3 moves back into the supporting surface of the base 1. At this time, the telescopic component 3 no longer provides positioning for the lower template 4, and the disassembly of the installation tooling can be completed, which facilitates the operation and improves the work efficiency of locking multiple groups of damping structures 71.

[0045] Specifically, in this embodiment, the first adsorption member 44 comprises a magnet. The magnet can generate an adsorption force on the fixing nut, ensuring that after the fixing nut is inserted into the second through hole 42, it is fixed in the lower template 4 by the adsorption force in the second through hole 42, preventing the fixing nut from falling onto the supporting surface of the base 1, thereby facilitating assembly and positioning.

[0046] Specifically, in this embodiment, a plurality of first adsorption components 44 are provided, and the plurality of first adsorption components 44 are spaced apart along the inner wall of the second through hole 42 in the circumferential direction. Two, three, five, or other first adsorption components 44 may be provided, and the number of first adsorption components 44 is not specifically limited. The plurality of first adsorption components 44 provide adsorption force to the fixing nut from different positions along the circumferential direction, as long as the first adsorption components 44 can adsorb the fixing nut and prevent it from falling onto the supporting surface of the base 1.

[0047] like Figure 1 and Figure 3 As shown, specifically, in this embodiment, the installation tool further includes a second adsorption component 45, which is provided in both the lower template 4 and the upper template 5. The second adsorption component 45 is used to adsorb and clamp the piston assembly 7. There may be one, two, or four second adsorption components 45, and the number of second adsorption components 45 is not specifically limited, as long as the second adsorption components 45 can adsorb and fix the lower surface of the piston assembly 7. When multiple second adsorption components 45 are provided, the multiple adsorption components can be arranged at intervals along the circumferential direction on the bearing surface of the lower template 4, so that the second adsorption components 45 provide a relatively uniform fixing force on the piston assembly 7, ensuring the stability and reliability of the installation tool in positioning the piston assembly 7.

[0048] like Figure 3 As shown, specifically, in this embodiment, the second adsorption component 45 includes a magnetic column, the axial direction of the magnetic column is perpendicular to the supporting surface of the lower template 4. The magnetic column is embedded in the lower template 4, and its axial direction is perpendicular to the supporting surface of the lower template 4. At this time, one end of the magnetic column is close to the piston assembly 7 in the exposed area of ​​the supporting surface of the lower template 4, which can provide an adsorption force along the axial direction of the magnetic column to bring the piston assembly 7 close to the lower template 4, ensuring that the piston assembly 7 does not move during the assembly process, thereby improving the positioning and assembly efficiency of the installation tool for the piston assembly 7.

[0049] like Figure 3 As shown, specifically, in this embodiment, a second locating pin 43 is further provided on a side of the lower template 4 away from the base 1. The second locating pin 43 is used to engage with the piston assembly 7. The operator only needs to align the mounting hole in the center of the piston assembly 7 with the second locating pin 43 and engage the second locating pin 43 with the mounting hole, which is convenient for operation.

[0050] In other embodiments, the upper mold plate 5 and the lower mold plate 4 have different structures, that is, the second positioning pins 43 of the upper mold plate 5 and the second positioning pins 43 of the lower mold plate 4 are installed symmetrically. This arrangement allows the upper mold plate 5 and the lower mold plate 4 to be assembled and positioned on different surfaces when the piston assembly 7 is installed, ensuring the stability and reliability of the positioning structure of the installation tool.

[0051] like Figure 2 As shown, specifically, in this embodiment, a groove is provided at the bottom of the lower template 4, and the installation tool also includes an elastic positioning steel ball 8. The telescopic end of the elastic positioning steel ball 8 can be moved out and retracted in the vertical direction relative to the supporting surface of the base 1. When the elastic positioning steel ball 8 is ejected, it cooperates with the groove to limit the lower template 4.

[0052] During operation, after the first through hole 41 of the lower template 4 is plugged and installed with the first positioning pin 2, the lower template 4 is rotated to adjust the placement position on the base 1, and the lower template 4 is rotated. When the groove of the lower template 4 is rotated to match the position of the elastic positioning steel ball 8, the elastic positioning steel ball 8 is pushed out of the supporting surface of the base 1 and embedded in the groove of the lower template 4, that is, the elastic positioning steel ball 8 and the groove of the lower template 4 complete the pre-positioning of the lower template 4, and then the telescopic component 3 is pushed to move, so that the telescopic end of the telescopic component 3 moves in the vertical direction to push out the supporting surface of the base 1 and extend into the second through hole 42 of the lower template 4, completing the positioning of the lower template 4, ensuring the stability and reliability of the positioning structure of the installation tooling, and easy operation.

[0053] like Figure 2 As shown, specifically, in this embodiment, the telescopic component 3 includes: a sliding rod 31, a rod cap 32 and an elastic reset member 33. The sliding rod 31 is slidably connected to the base 1, and the axial direction of the sliding rod 31 is parallel to the axial direction of the first positioning pin 2. One end of the sliding rod 31 pushes out of the supporting surface of the base 1 and penetrates into the second through hole 42 for cooperating with the positioning lower template 4; the rod cap 32 is arranged at the other end of the sliding rod 31; the elastic reset member 33 is cooperating with the sliding rod 31, and the two ends of the elastic reset member 33 are respectively connected to the rod cap 32 and the bottom surface of the base 1.

[0054] During operation, the operator only needs to provide a pushing force to one end of the rod cap 32, so that the rod cap 32 drives the sliding rod 31 to continuously compress the elastic reset member 33 in a direction parallel to the axis of the first positioning pin 2, and the distance between the rod cap 32 and the bottom surface of the base 1 gradually decreases. The sliding rod 31 passes through the base 1 and continuously extends toward the second through hole 42 of the lower template 4, completing the position limiting work of the lower template 4. Exemplarily, the elastic reset member 33 can be a compression spring, an elastic rubber sleeve or other structural components with elastic compression function. The elastic reset member 33 is not specifically limited here. The elastic reset member 33 is sleeved with the sliding rod 31. The structure is compressible and can rebound after compression, which reduces the space occupied by the telescopic component 3, making the structure compact and easy to operate.

[0055] At the same time, the utility model also provides a locking device for an installation tool, including: a first drive device, a second drive device and an installation tool as described above, the drive end of the first drive device is connected to the telescopic part 3, the first drive device is used to provide a force for the telescopic part 3 to move along the telescopic direction, the drive end of the second drive device is fixedly connected to the end of the locking head 6 away from the assembly groove 61, and the second drive device is used to provide a torque to the locking head 6 to rotate around the axis direction of the locking head 6.

[0056] During operation, after the operator completes the assembly of the installation tool, he first activates the first drive device to push the telescopic end of the telescopic component 3 to complete the positioning of the lower template 4, and then activates the second drive device to kick the locking head 6 to generate a rotating torque to complete the locking of a set of damping structures 71 in the piston assembly 7. The first and second drive devices are closed to retract the telescopic end of the telescopic component 3 into the supporting surface of the base 1, and the disassembly of the installation tool is completed, which facilitates operation and improves the efficiency of positioning and locking the damping component in the piston assembly 7. The first drive device can be a pneumatic cylinder or other structure that can provide a driving force for the telescopic component 3, and the first drive device is not specifically limited here.

[0057] Specifically, in this embodiment, the locking device of the installation tool also includes: a sensor and a controller, the sensor is connected to the driving end of the second driving device, and the sensor is used to detect the torque information of the second driving device rotating around the axis direction of the locking head 6; the controller is controlled and connected to the sensor, the first driving device and the second driving device, and the controller is used to control the movement of the driving end of the second driving device and the driving end of the first driving device according to the torque information detected by the sensor.

[0058] During operation, the operator only needs to input the required locking force value of the damping structure 71 into the controller, start the first drive device and the second drive device, and the sensor will feed back the detected torque information to the controller. When the torque information reaches the required locking force value, the controller controls the first drive device and the second drive device to close, and the locking work of a group of damping structures 71 can be completed. Compared with the traditional manual method of locking the damping structures 71 one by one with a wrench, this application realizes accurate control of the locking force value through the controller and the sensor, saves manpower, and improves the locking efficiency of the damping components in the piston assembly 7.

[0059] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0060] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
