[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0039] Please refer to the following Figure 1-Figure 9 A valve spring pressing tool 100 according to an embodiment of the present utility model is described.

[0040] Reference Figure 2 , Figure 3 and Figure 4 According to an embodiment of the utility model, the valve spring pressing tool 100 includes: a support frame 10, a pressure rod 20, a driving rod 30 and a locking mechanism 40.

[0041] Specifically, the pressure rod 20 is arranged on the support frame 10 and can move between an initial position and a clamping position. The pressure rod 20 has a pressure-applying portion, and the pressure rod 20 is configured to: push and compress the valve spring through the pressure-applying portion when moving from the initial position to the clamping position; the driving rod 30 is arranged on the support frame 10, and the driving rod 30 is connected to the pressure rod 20 for driving the pressure rod 20 to move between the initial position and the clamping position; the locking mechanism 40 is arranged on the support frame 10, and the locking mechanism 40 has a locking state and a releasing state. In the locking state, the locking mechanism 40 is suitable for locking the pressure rod 20, and in the releasing state, the locking mechanism 40 releases the pressure rod 20.

[0042] For example, Figure 2 , Figure 3 and Figure 4As shown, the support frame 10 is extended in the up-down direction, the pressure rod 20 is extended in the up-down direction and moves between the initial position and the pressing position in the up-down direction, the upper end of the pressure rod 20 is fixed to the support frame 10, and the lower end of the pressure rod 20 is the pressure end.

[0043] When the valve spring compression tool 100 is used to compress the valve spring, the pressure rod 20 is initially in the initial position and the driving rod 30 does not drive the pressure rod 20. When the pressure rod 20 is needed to compress the valve spring, the driving rod 30 drives the pressure rod 20 to move from the initial position to the compression position until the pressure end of the pressure rod 20 compresses the valve spring to a suitable position. At this time, the locking mechanism 40 locks the pressure rod 20 and then installs components to the valve. After the components are installed, the locking mechanism 40 releases the pressure rod 20 and the pressure rod 20 moves from the compression position to the initial position. At this time, the valve spring compression work is completed.

[0044] The valve spring compression tool 100 of the utility model is provided with a locking mechanism 40. When the pressure rod 20 compresses the valve spring, the locking mechanism 40 locks the pressure rod 20, and the pressure rod 20 cannot move, so that the pressure rod 20 can stably compress the valve spring. Compared with the solution of manually compressing the valve spring in the prior art, the valve spring compression tool 100 of this embodiment can stably compress the valve spring, so that it is convenient to install parts on the valve, improve the installation efficiency, and at the same time, it can prevent the spring from releasing the elastic force to push the pressure rod 20 out, so as to ensure production safety and reduce production risks. In addition, the pressure rod 20 can move between the initial position and the compression position, and the stepless adjustment of the movement of the pressure rod 20 can be realized, so that it can adapt to the installation of valves of different heights, and effectively improve the versatility of the valve spring compression tool 100.

[0045] According to the valve spring pressing tool 100 of the embodiment of the utility model, a locking mechanism 40 is provided, and the locking mechanism 40 stably locks the pressure rod 20, which can facilitate the installation of parts on the valve, ensure production safety, and reduce production risks.

[0046] According to some embodiments of the present invention, referring to Figure 2 and Figure 4 When the pressure rod 20 is in the clamping position, the locking mechanism 40 is adapted to switch to a locking state to lock the pressure rod 20 in the locking position. Thus, the locking mechanism 40 can lock the pressure rod 20 in the locking state, thereby preventing the valve spring from pushing the pressure rod 20 to cause danger, thereby improving production safety.

[0047] According to some embodiments of the present invention, referring to Figure 2 and Figure 3The support frame 10 is provided with a rotating shaft 12, which can rotate relative to the support frame 10, a pressure rod 20 is fixedly connected to the rotating shaft 12, and a driving rod 30 is connected to the rotating shaft 12 for driving the rotating shaft 12 to rotate. Thus, the rotation of the pressure rod 20 can drive the rotating shaft 12 to rotate, and the rotating shaft 12 can rotate relative to the support frame 10. When the pressure rod 20 moves between the initial position and the clamping position, it can drive the rotating shaft 12 to rotate.

[0048] For example, Figure 2 and Figure 3 As shown, the rotating shaft 12 is extended in the left-right direction, and the pressure rod 20 is fixedly connected to the rotating shaft 12. When the pressure rod 20 moves in the up-down direction, the pressure rod 20 drives the rotating shaft 12 to rotate.

[0049] According to some optional embodiments of the present invention, referring to Figure 2 , Figure 5 and Figure 6 The locking mechanism 40 includes a brake disc 41 and a clamping member 42. The brake disc 41 is coaxially fixed to the rotating shaft 12; the clamping member 42 has a clamping groove 421, and a portion of the brake disc 41 extends into the clamping groove 421. The clamping member 42 is configured to clamp the brake disc 41 located in the clamping groove 421 when the locking mechanism 40 is in the locked state.

[0050] In this way, the clamping member 42 is provided with a clamping groove 421. When the clamping member 42 does not clamp the brake disc 41, the brake disc 41 can rotate in the clamping groove 421, so that the clamping groove 421 can provide a rotation space for the brake disc 41. At the same time, when the clamping member 42 clamps the brake disc 41, the clamping member 42 only needs to clamp the brake disc 41 in the clamping groove 421, thereby reducing the clamping area of ​​the clamping member 42, and further facilitating the clamping of the brake disc 41 by the clamping member 42.

[0051] For example, Figure 5 and Figure 6 As shown, a clamping groove 421 is provided on the front side of the clamping member 42, and the clamping groove 421 is formed by being recessed inward from the front side edge of the clamping member 42, and the clamping groove 421 penetrates the clamping member 42 in the up-down direction, and the brake disc 41 is disc-shaped, and the brake disc 41 is fixed to the left side of the rotating shaft 12. When the clamping member 42 does not clamp the brake disc 41, the brake disc 41 can rotate in the clamping groove 421, and when the clamping member 42 clamps the brake disc 41, the clamping member 42 clamps the brake disc 41 in the clamping groove 421, and the brake disc 41 cannot rotate.

[0052] According to some optional embodiments of the present invention, referring to Figure 2 and Figure 6 The clamping member 42 is a pneumatic caliper. The pneumatic caliper locks the brake disc 41 through compressed air, thereby ensuring the stability of the clamping member 42 locking the brake disc 41 and effectively preventing the brake disc 41 from rotating.

[0053] According to some embodiments of the present invention, referring to Figure 2 and Figure 7 The locking mechanism 40 further includes: a mounting bracket 43, one end of the mounting bracket 43 (such as Figure 2 The lower end of the mounting bracket 43 shown in the figure) is fixed to the support frame 10, and the clamping member 42 is fixed to the other end of the mounting bracket 43 (as shown in the figure) Figure 2 Thus, the support frame 10 provides a fixed position for the mounting bracket 43, which can facilitate the fixing of the mounting bracket 43. At the same time, the mounting bracket 43 provides a fixed position for the clamping member 42, which can facilitate the fixing of the clamping member 42. In addition, the clamping member 42 is fixed to the support frame 10 through the mounting bracket 43, thereby preventing the clamping member 42 from being separated from the support frame 10.

[0054] For example, Figure 2 and Figure 7 As shown, the mounting bracket 43 is extended in the up-down direction, the upper end of the mounting bracket 43 is connected to the clamping member 42 , and the lower end of the mounting bracket 43 is fixedly connected to the support frame 10 .

[0055] According to some embodiments of the present invention, referring to Figure 2 and Figure 8 The valve spring clamping tool 100 further includes: a damper 50, which is fixed on the support frame 10, and the damping end of the damper 50 is fixed to the rotating shaft 12. The damper 50 is configured to provide a damping force for the rotating shaft 12 when the pressure rod 20 moves from the clamping position to the initial position. When the pressure rod 20 moves from the clamping position to the initial position, the valve spring releases its elastic force, which causes the valve spring to push the pressure rod 20 to move quickly. Therefore, the damper 50 provides a damping force for the pressure rod 20, thereby preventing the pressure rod 20 from moving quickly, thereby ensuring production safety and improving production safety.

[0056] For example, Figure 2 and Figure 8 As shown, the damper 50 is fixed on the support frame 10, and the damping end of the damper 50 is fixed on the right side of the rotating shaft 12. When the pressure rod 20 moves upward from the clamping position to the initial position, the damping end interacts with the damper 50 to provide a damping force for the pressure rod 20, thereby preventing the pressure rod 20 from moving quickly.

[0057] According to some optional embodiments of the present invention, referring to Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 The damper 50 and the locking mechanism 40 are arranged in the axial direction of the rotating shaft 12 (such as Figure 3 The two ends of the rotating shaft 12 (as shown in the left and right directions) Figure 3Thus, the damper 50 and the locking mechanism 40 are arranged at both ends of the rotating shaft 12, so that the locking mechanism 40 can lock the pressure rod 20, and the damper 50 can provide a damping force to the pressure rod 20, so that the structure of the valve spring pressing tool 100 is reasonably arranged, and the normal operation of the valve spring pressing tool 100 is ensured.

[0058] For example, Figure 2 As shown, the rotating shaft 12 is arranged to extend in the left-right direction, the damper 50 is arranged at the right end of the rotating shaft 12 , and the locking mechanism 40 is arranged at the left end of the rotating shaft 12 .

[0059] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The support frame 10 includes two support arms 11 arranged at intervals, and the support arms 11 are formed with shaft holes, and the two ends of the rotating shaft 12 (such as Figure 3 The left and right ends of the rotating shaft 12 shown in the figure are rotatably matched in the shaft holes of the two support arms 11. Therefore, the two support arms 11 can ensure the strength of the support frame 10, and at the same time, can also ensure that the support frame 10 can support the rotating shaft 12, the mounting bracket 43, the pressure rod 20 and other structures. In addition, the support arm 11 is provided with a shaft hole, which can facilitate the rotation shaft 12 to pass through the shaft hole, thereby facilitating the installation of the rotation shaft 12.

[0060] For example, Figure 2 and Figure 3 As shown, the support arm 11 extends in the up-down direction, and the two support arms 11 are arranged at intervals in the left-right direction. The upper side of the support arm 11 is provided with an axial hole that penetrates the support arm 11 in the left-right direction, and the left and right ends of the rotating shaft 12 pass through the axial holes of the corresponding support arms 11.

[0061] According to some embodiments of the present invention, referring to Figure 2 and Fig. 9 The valve spring pressing tool 100 further includes: a connecting arm 60, the connecting arm 60 extending in the radial direction of the rotating shaft 12, one end of the connecting arm 60 (such as Figure 2 The rear end of the connecting arm 60 shown in FIG. 1 is sleeved and fixed on the rotating shaft 12, and the pressure rod 20 and the driving rod 30 are arranged at intervals at the other end of the connecting arm 60 (as shown in FIG. Figure 2 As a result, the connecting arm 60 can connect the pressure rod 20 and the driving rod 30 to the rotating shaft 12. When the driving rod 30 drives the pressure rod 20 to move, the pressure rod 20 can drive the rotating shaft 12 to rotate through the connecting arm 60, thereby realizing the transmission between the pressure rod 20 and the rotating shaft 12. At the same time, the pressure rod 20 and the driving rod 30 are fixed to different ends of the connecting arm 60 from the rotating shaft 12, so that the normal movement of the pressure rod 20 is not affected, thereby ensuring the normal operation of the valve spring clamping tool 100.

[0062] For example, Figure 2 and Fig. 9 As shown, the connecting arm 60 is arranged to extend in the front-to-back direction, the front end of the connecting arm 60 is connected to the pressing rod 20 and the driving rod 30, and the rear end of the connecting arm 60 is connected to the rotating shaft 12. When the driving rod 30 rotates to drive the pressing rod 20 to move up and down, the pressing rod 20 drives the connecting arm 60 to rotate; and the connecting arm 60 drives the rotating shaft 12 to rotate.

[0063] According to some embodiments of the present invention, referring to Figure 2 , Figure 3 , Figure 4 and Fig. 9 , one end of the pressure rod 20 (such as Figure 2 The upper end of the pressure rod 20 shown in FIG. 1 is connected to the connecting arm 60, and the other end of the pressure rod 20 (as shown in FIG. Figure 2 The lower end of the pressure rod 20 shown in the figure extends away from the connecting arm 60 in a direction perpendicular to the length of the connecting arm 60, and the pressure-applying portion is formed at the other end of the pressure rod 20. Thus, the pressure rod 20 is connected to the connecting arm 60, which can ensure that the pressure rod 20 drives the connecting arm 60 to rotate, and at the same time, the other end of the pressure rod 20 forms the pressure-applying portion, which can ensure that the pressure-applying portion can compress the valve spring.

[0064] For example, Figure 2 and Figure 4 As shown, the pressure rod 20 is extended in the up-down direction, the upper end of the pressure rod 20 is connected to the connecting arm 60, and the lower end of the pressure rod 20 forms a pressure applying portion.

[0065] Furthermore, if Figure 2 and Figure 4 As shown, the driving rod 30 is formed as a driving handle, and one end of the driving rod 30 (such as Figure 2 The rear end of the driving rod 30 shown in FIG. 1 is connected to the connecting arm 60, and the other end of the driving rod 30 (as shown in FIG. Figure 2 The front end of the driving rod 30 shown in FIG. 1 is along the length direction of the connecting arm 60 (eg Figure 2 The front-to-rear direction of the connecting arm 60 shown in the figure extends outward away from the connecting arm 60. Therefore, when the driving rod 30 drives the pressing rod 20 to move, the driving rod 30 can drive the connecting arm 60 to move, and the connecting arm 60 can drive the rotating shaft 12 to rotate, so that the rotating shaft 12 can rotate synchronously with the driving rod 30. At the same time, the driving rod 30 extends in a direction away from the connecting arm 60, which can facilitate the application of pressure to the driving rod 30, and then facilitate the driving rod 30 to drive the pressing rod 20 to press the valve spring, so that the valve spring pressing tool 100 has a reasonable structure and is easy to operate.

[0066] For example, Figure 2 and Figure 4As shown, the drive rod 30 is extended in the front-to-back direction, the rear end of the drive rod 30 is connected to the connecting arm 60, the front end of the drive rod 30 extends forward, and the end of the drive rod 30 is formed as a ball end, so that it is further convenient to apply pressure to the drive rod 30.

[0067] According to the valve lock clip installation device 1000 of the second embodiment of the utility model, refer to Figure 1 and Figure 2 , comprising: a workbench 200, a mounting beam 300 and a valve spring pressing tool 100 of the first aspect of this embodiment. The workbench 200 is provided with a tray 220 for fixing the cylinder head of the engine; the mounting beam 300 is arranged on the workbench 200 and extends upward; the valve spring pressing tool 100 is arranged on the upper part of the mounting beam 300 (such as Figure 1 The pressure-applying portion of the pressure rod 20 is adapted to abut against the valve spring on the cylinder head to push and compress the valve spring.

[0068] For example, Figure 1 and Figure 2 As shown, the workbench 200 is placed on the ground, the tray 220 is placed on the surface of the workbench 200, the cylinder head is arranged on the tray 220, the mounting beam 300 is extended in the up and down directions, the lower end of the mounting beam 300 is connected to the workbench 200, and the upper end of the mounting beam 300 is connected to the valve spring clamping tool 100.

[0069] When using the valve lock clamp installation device 1000 to install the valve lock clamp, first place the cylinder head on the tray 220, then use the valve spring clamping tool 100 to compress the valve spring, and then install the valve lock clamp. After the valve lock clamp is installed, the valve spring clamping tool 100 moves to the next valve lock clamp installation position.

[0070] According to the valve lock clamp installation device 1000 of the embodiment of the utility model, by setting the valve spring clamping tool 100 of the first embodiment, a locking mechanism 40 is set on the valve spring clamping tool 100, and the locking mechanism 40 stably locks the pressure rod 20, which can facilitate the installation of parts on the valve, and can also ensure production safety and reduce production risks. In addition, the tray 220 can provide a placement position for the cylinder head, so that the placement of the cylinder head can be convenient, and the mounting beam 300 can make the height of the valve spring clamping tool 100 higher than the workbench 200, so that the valve spring clamping tool 100 can be convenient for clamping the valve spring. In addition, when installing the lock clamp, only one person is needed to complete the clamping of the valve spring and the installation of the valve lock clamp, thereby improving production efficiency and reducing production costs.

The driving rod 30 rotates clockwise, and the driving rod 30 drives the pressure rod 20 to move downward from the initial position to the clamping position. When the pressure rod 20 moves downward, the driving rod 30 and the pressure rod 20 drive the connecting arm 60 to rotate, and the connecting arm 60 is connected. The connecting arm 60 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the brake disc 41 to rotate. When the pressure rod 20 presses the valve spring to a suitable position, the clamping member 42 switches from a released state to a locked state, and the clamping member 42 locks the brake disc 41 in the clamping groove 421. At this time, the pressure rod 20 does not move, and then the valve lock clamp is installed. After the valve lock clamp is installed, the clamping member 42 switches from a locked state to a released state, and the clamping member 42 no longer locks the brake disc 41. The valve spring releases elastic force to push the pressure rod 20 upward. At this time, the damper 50 provides a damping force for the rotation of the rotating shaft 12, thereby providing a damping force for the movement of the pressure rod 20. The pressure rod 20 moves slowly upward until the pressure rod 20 moves to the initial position. At this time, a valve lock clamp is installed. Then, the position of the valve spring pressing tool 100 is moved to the installation position of the next valve lock clamp, and the above steps are repeated until all valve lock clamps are installed.

[0076] The valve lock clamp installation device 1000 of the utility model is provided with the valve spring clamping tool 100 of the first embodiment described above, and a locking mechanism 40 is provided on the valve spring clamping tool 100. The locking mechanism 40 stably locks the pressure rod 20, which can facilitate the installation of parts on the valve, and can also ensure production safety and reduce production risks. In addition, the tray 220 can provide a placement position for the cylinder head, thereby facilitating the placement of the cylinder head, and the mounting beam 300 can make the height of the valve spring clamping tool 100 higher than the workbench 200, thereby facilitating the valve spring clamping tool 100 to clamp the valve spring. Furthermore, when installing the lock clamp, only one person is needed to complete the clamping of the valve spring and the installation of the valve lock clamp, thereby improving production efficiency and reducing production costs.
