[0007] Preferably, a fixed nut is screwed on the end of the connecting bolt in the positioning recess, so that the lower end of the connecting bolt is fixed in the positioning recess.

[0008] Another technical problem to be solved by the present application is to provide a method for using the inside spoiler actuating cylinder spring seat dismounting assembly, comprising the following steps:

[0009] When disassembling:

[0010] S1: adjust the piston rod of the actuating cylinder shell to the fully extended position, sequentially sleeve the support block positioning sleeve and the positioning hole at the left end of the loading support block on the piston rod, so that the lower end of the first threaded hole is opposite to the installation hole on the actuating cylinder shell;

[0011] S2: after assembling the positioning rod, the positioning sleeve, the connecting bolt and the balance spring, the positioning rod is screwed into the first threaded through hole; the positioning rod is rotated downward so that the stepped horizontal surface of the positioning rod is kept horizontal with one positioning surface at the upper end of the loading support block, at this time, the spring and the balance spring are simultaneously in the maximum compression state; then the compression nut is tightened;

[0012] S3: the upper end of the synchronous open wrench is clamped on the hexagonal rod body at the bottom end of the positioning rod, and the lower connecting body at the lower end of the synchronous open wrench is clamped on the outer surface of the upper end of the hexagonal spring top seat;

[0013] S4: the synchronous open wrench is rotated, so that the spring top seat and the positioning rod are synchronously moved upward, since the thread pitch of the positioning rod is twice that of the thread pitch of the spring top seat, when the spring top seat moves upward by one unit, the positioning rod moves upward by two units, that is, the positioning rod moves upward by one unit relative to the spring top seat, therefore, the spring and the balance spring are each elongated by one unit amount; therefore, the upward pressure of the spring and the downward load of the balance spring are always the same in the process of rotation, can be mutually offset, so that the rotation of the synchronous open wrench is very easy, simple and convenient, time and labor are saved.

[0014] When installing:

[0015] S5: after installing the fixed loading support block, the positioning rod, the positioning sleeve, the connecting bolt and the balance spring are assembled, and then the positioning rod is screwed into the first threaded through hole;

[0016] S6: the spring top seat is screwed into the mounting hole in the actuator cylinder shell, and then the stepped horizontal surface of the positioning rod is rotated downward so as to keep horizontal with another positioning surface at the upper end of the loading support block, at this time, the spring and the balance spring are both in the normal length state;

[0017] S7: the spring top seat and the positioning rod are simultaneously rotated using the synchronous open wrench and the lower connecting body, so that the spring top seat and the positioning rod are synchronously moved downward, and the upward pressure of the spring and the downward load of the balance spring are always the same in the process of rotation, can be mutually offset, so that the rotation of the synchronous open wrench is very easy, simple and convenient, time and labor are saved.

[0018] Compared with the prior art, the beneficial effects of the present application are:

[0019] When disassembling the spring seat, the piston rod of the actuator cylinder shell is adjusted to the fully extended position, the support block positioning sleeve, the loading support block and the compression nut are installed, and the parts of the actuator cylinder body are used as positioning connecting pieces to firmly install and fix the position of the disassembled assembly;

[0020] Meanwhile, when disassembling and assembling the spring top seat, the connection of the synchronous open-end wrench allows the positioning rod, positioning sleeve, and spring top seat to move up and down synchronously. The ingenious design that the thread pitch on the positioning rod is twice the thread pitch on the spring top seat installed in the mounting hole of the actuator housing ensures that the length of the balance spring and the spring remain dynamically consistent. This allows the balance spring to apply a follow-up load of the same magnitude as the spring force synchronously, thereby canceling out the spring force. The rotation of the synchronous open-end wrench makes the disassembly and assembly of the spring top seat convenient, quick, and time-saving. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] See Figures 1-5An assembly and usage method for assembling and disassembling an inner spoiler actuator spring seat includes a support block positioning sleeve 2 and a loading support block 3. The support block positioning sleeve 2 is fitted over the piston rod 11 that extends fully out of the actuator housing 1. The loading support block 3 has a positioning hole 301 at its left end, which is fitted over the piston rod 11 at the upper end of the support block positioning sleeve 2. A clamping nut 4 is screwed onto the bolt head 12 at the upper end of the piston rod 11, and the clamping nut 4 presses against the upper surface of the loading support block 3. The loading support block 3 also has two positioning planes for positioning the loading support block 3. The loading support block 3 is fixed in place; a first threaded through hole 302 is provided at the right end of the loading support block 3, and a positioning rod 5 with a stepped upper end is screwed into the first threaded through hole 302. The thread pitch on the positioning rod 5 is twice the thread pitch on the spring top seat 14 installed in the mounting hole 101 of the actuator cylinder housing 1, ensuring that the vertical displacement of the positioning rod 5 is twice that of the spring top seat 14 for each rotation. The bottom end of the positioning rod 5 is hexagonal, and a first through hole 501 is provided at the upper end of the positioning rod 5. A second through hole 5 with a reduced diameter is provided at the lower end of the first through hole 501. 02. A third through hole 503 with an increased diameter is provided at the lower end of the second through hole 502. A positioning sleeve 6 is fitted inside the third through hole 503. The positioning sleeve 6 can move up and down within the third through hole 503. A positioning groove 602 is provided at the bottom of the positioning sleeve 6. A through second threaded through hole 601 is provided at the upper end of the positioning groove 602. A plane bearing is provided at the upper end of the third through hole 503. The upper end of the balance spring 8 presses against the plane bearing. The plane bearing enables the balance spring 8 to rotate stably. The specifications of the balance spring 8 are consistent with those of the actuator cylinder housing 1. The spring 13 inside the mounting hole 101 is the same. The lower end of the balance spring 8 presses against the upper end of the positioning sleeve 6. The head of the connecting bolt 7 is provided in the first through hole 501. The connecting bolt 7 passes downward through the second through hole 502 and the third through hole 503 and is threadedly connected to the second threaded through hole 601. A fixing nut 71 is screwed to the end of the connecting bolt 7 located in the positioning groove 602, so that the lower end of the connecting bolt 7 is fixed in the positioning groove 602. The positioning groove 602 presses against the upper end of the spring top seat 14 of the actuator housing 1, so that the spring top seat 14 is firmly fixed. A synchronous open-end wrench 9 is connected to the hexagonal rod body at the bottom end of the positioning rod 5. A lower connecting body 91 is provided at the lower end of the synchronous open-end wrench 9. The lower connecting body 91 is connected to the outer surface of the upper end of the hexagonal spring top seat 14. Through the connection of the synchronous open-end wrench 9, the positioning rod 5, the positioning sleeve 6 and the spring top seat 14 move up and down synchronously.

[0029] A method for using an inner spoiler actuator spring seat assembly includes the following steps:

[0030] During disassembly:

[0031] S1: Adjust the piston rod 11 of the actuator housing 1 to the fully extended position, and put the positioning sleeve 2 of the support block and the positioning hole 301 at the left end of the loading support block 3 onto the piston rod 11 in sequence, so that the lower end of the first threaded through hole 302 is directly opposite the mounting hole 101 on the actuator housing 1.

[0032] S2: After assembling the positioning rod 5, positioning sleeve 6, connecting bolt 7, and balance spring 8, thread the positioning rod 5 into the first threaded through hole 302; rotate it downwards so that the stepped horizontal surface of the positioning rod 5 is aligned with a positioning surface at the upper end of the loading support block 3. At this time, the spring 13 and the balance spring 8 are simultaneously in the maximum compression state; then tighten the clamping nut 4.

[0033] S3: The upper end of the synchronous open wrench 9 bites into the hexagonal rod body at the bottom of the positioning rod 5, while the lower connecting body 91 of the synchronous open wrench 9 bites into the upper outer surface of the hexagonal spring top seat 14.

[0034] S4: Rotate the synchronous open-end wrench 9 to make the spring top seat 14 and the positioning rod 5 move upward synchronously. Since the thread pitch of the positioning rod 5 is twice that of the thread pitch of the spring top seat 14, when the spring top seat 14 moves upward by one unit, the positioning rod 5 moves upward by two units. That is, the positioning rod 5 moves upward relative to the spring top seat 14 by one unit. Therefore, the spring 13 and the balance spring 8 each extend by one unit. Thus, during the rotation, the upward pressure of the spring 13 and the downward load of the balance spring 8 are always the same and can cancel each other out, making the rotation of the synchronous open-end wrench 9 very easy, simple, convenient, time-saving and labor-saving.

[0035] During installation:

[0036] S5: After installing the fixed loading support block 3, assemble the positioning rod 5, positioning sleeve 6, connecting bolt 7, and balance spring 8, and then thread the positioning rod 5 into the first threaded through hole 302.

[0037] S6: Thread the spring top seat 14 into the mounting hole 101 on the actuator housing 1, and then rotate it downwards so that the stepped horizontal plane of the positioning rod 5 is in the same horizontal position as the other positioning surface at the upper end of the loading support block 3. At this time, the spring 13 and the balance spring 8 are in the normal length state.

[0038] S7: Using the simultaneous open-end wrench 9 and the lower connecting body 91, rotate the spring top seat 14 and the positioning rod 5 simultaneously, so that the spring top seat 14 and the positioning rod 5 move downward synchronously. Similarly, during the rotation, the upward pressure of the spring 13 and the downward load of the balance spring 8 are always the same and can cancel each other out, making the rotation of the simultaneous open-end wrench 9 very easy, simple and convenient, saving time and effort.
