[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1: A vehicle shock absorber valve seat assembly fixture, such as Figure 1-Figure 3 As shown, it includes a clamp base 1, the top of the clamp base 1 radially protrudes to form a flange 2, and a cavity 3 for accommodating the valve seat is opened inside the flange 2. For the convenience of assembly, the flange 2 is radially opened with a taking groove 4 communicated with the cavity 3. After assembly, the valve seat is taken out from the side wall of the valve seat through the taking groove 4, and the hexagonal structure in the cavity 3 is used to circumferentially limit the valve seat. When the valve seat is installed, the valve seat is controlled to be unable to rotate freely, thereby realizing the clamping function.

[0025] In particular, a rotating groove 5 is provided on the bottom end surface of the flange 2, and a rotating rail 6 is movably installed in the rotating groove 5. The rotating rail 6 can rotate around the axis of the clamp base 1 in the rotating groove 5, and an extension plate 7 is fixedly installed on the rotating rail 6 corresponding to the position of the picking groove 4. The edge of the extension plate 7 radially extends to the outside of the flange 2 and is fixedly installed with a clamping plate 8. The top of the clamping plate 8 extends to the top of the flange 2 and is fixedly installed with a clamping block 9. The clamping block 9 extends radially toward the middle of the clamp base 1, wherein the clamping plate 8 is an elastic plastic part. When the valve seat is installed in the cavity 3, the clamping plate 8 is squeezed to cause the clamping plate 8 to undergo elastic deformation until the valve seat falls into the cavity 3 and is clamped under the clamping block 9, so that the valve seat is more stable under the pressure of the clamping block 9 at this time, thereby increasing the stability of the clamp, and the circumferential position of the clamping plate 8 and the valve seat can be adjusted at any time to meet the installation requirements of different valve seats.

[0026] Furthermore, extension grooves 10 are obliquely provided on both sides of the clamping block 9, so that both ends of the clamping block 9 form a trapezoidal structure, which reduces the contact area with the valve seat and reduces the friction when the clamping plate 8 turns.

[0027] Furthermore, the rotating groove 5 is an L-shaped groove, and the rotating rail 6 is a ring with an L-shaped cross-section that cooperates with the rotating groove 5, so that the rotating rail 6 is not easy to fall off. To facilitate the installation of the rotating rail 6, the bottom surface of the flange 2 close to the clamp base 1 is designed to be detachable. After the rotating rail 6 is inserted into the rotating groove 5 from the bottom, the separated part of the flange 2 is fixed to the flange 2 as a whole by means of screws 14 or the like.

[0028] In this embodiment, the valve seat is pressed downward, and under the guidance of the clamping block 9, the clamping plate 8 is tilted and deformed outward, and finally the valve seat is clamped in the position between the clamping block 9 and the flange 2, and cooperates with the cavity 3 to fix the valve seat as a whole, which cannot rotate and swing freely, and is convenient for assembly. After assembly, the clamping plate 8 is rotated to the taking slot 4, and the gap in the taking slot 4 is used to pull open the clamping plate 8 to remove the valve seat.

[0029] Embodiment 2, a vehicle shock absorber valve seat assembly fixture, such as Figure 4 As shown, the difference between this embodiment and the first embodiment is that the clamping plate 8 is slidably installed in the extension plate 7 and can slide up and down along the extension plate 7 to adapt to valve seats of different heights. The specific structure is as follows:

[0030] Among them, the outer support of the extension plate 7 is provided with a slide groove 11, the clamping plate 8 passes through the slide groove 11 and can slide up and down in the slide groove 11, the bottom end surface of the clamping plate 8 is located below the extension plate 7 and a bottom plate 12 is fixedly installed, the inner edge of the bottom plate 12 radially extends toward the clamp base 1 and overlaps with the extension plate 7, and a spring 16 is fixedly installed between the bottom plate 12 and the extension plate 7, so that the elastic force of the spring 16 is utilized to press the clamping block 9 downward to fix the valve seat.

[0031] In a preferred embodiment, a thread hole 13 is opened in the bottom plate 12 at a position corresponding to the bottom of the spring 16, a screw 14 is connected to the inner thread of the thread hole 13, a top plate 15 is movably connected to the top of the screw 14, the top plate 15 can rotate around the screw 14, the top plate 15 is fixedly connected to the spring 16, when it is necessary to adjust the clamping force of valve seats of different heights, the screw 14 is rotated so that the top plate 15 squeezes the spring 16, allowing the spring 16 to generate elastic forces of different strengths, thereby changing the force with which the clamping block 9 presses down to clamp the valve seat, and also facilitating the removal of the valve seat.

[0032] The working principle of the utility model is as follows: the valve seat is pressed down, and under the guidance of the clamping block 9, the clamping plate 8 is tilted and deformed outward, and finally the valve seat is clamped in the position between the clamping block 9 and the flange 2, and cooperates with the cavity 3 to fix the valve seat as a whole, and it cannot rotate and swing freely, which is convenient for assembly. After the assembly is completed, the clamping plate 8 is rotated to the taking slot 4, and the gap in the taking slot 4 is used to pull open the clamping plate 8 to take out the valve seat.

[0033] In addition, the clamping plate 8 with variable height is used to clamp valve seats of different thicknesses, and the clamping force of the valve seat is controlled by the spring 16 with variable elastic force, so that the valve seat can be easily removed after assembly.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
