[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0029] Reference Figures 1 to 2As shown, this embodiment provides a valve spring lower seat quantitative material removal tool, including a mounting seat 1, a storage tube 2 and a material stripping plate 3, a plurality of valve spring lower seats 4 are stacked in the storage tube 2, and a discharge port is provided at the lower end of the storage tube 2; a slide groove 21 is vertically provided at the front end of the storage tube 2, and a counterweight block 22 is slidingly provided in the storage tube 2, and the counterweight block 22 is located on the top of the stacked plurality of valve spring lower seats 4; a drive rod 23 is provided on the counterweight block 22, and the drive rod 23 extends out of the slide groove 21.

[0030] When implementing it specifically, Figure 2 As shown, before taking out the valve spring lower seats 4 in a quantitative manner, it is necessary to first stack a sufficient amount of valve spring lower seats 4 in multiple storage tubes 2. The specific operation is to first drive the counterweight block 22 to move upward through the driving rod 23, take out the counterweight block 22, and then place several valve spring lower seats 4 in the storage tube 2 in a uniform direction. When the stack is almost full, put the counterweight block 22 into the storage tube 2 and press it on the top of several valve spring lower seats 4. The valve spring lower seats 4 located below fall out under the action of gravity and the counterweight block 22 and are stacked on the mounting seat 1 below the storage tube 2.

[0031] like Figure 1 and Figure 2 As shown, a number of storage tubes 2 are suspended on the mounting seat 1, usually two are arranged in the left and right directions, but the specific number depends on actual needs. At least one valve spring lower seat 4 is stacked between the discharge port and the mounting seat 1. More specifically, the height of the lower end of the storage tube 2 from the mounting seat 1 is equal to the height of the multiple valve spring lower seats 4 required to be stacked; the number of valve spring lower seats 4 stacked between the lower ends of the storage tubes 2 and the mounting seat 1 after multiple storage tubes 2 fall out is the total amount required by an engine. For example, an ordinary 4-cylinder engine is equipped with a total of 16 valve spring lower seats 4, and then 8 valve spring lower seats 4 are stacked under each of the two storage tubes 2.

[0032] More specifically, Figure 2 As shown, the stripping plate 3 is slidably arranged between the mounting seat 1 and the storage tube 2 in the front-rear direction. The thickness of the stripping plate 3 is equal to the height of the lower end of the storage tube 2 from the mounting seat 1, and the valve spring lower seat 4 accumulated below the discharge port is pushed out by the stripping plate 3; and then the stripping plate 3 is driven to move forward, and the valve spring lower seat 4 stacked below the two storage tubes 2 can be pushed out of the storage tube 2, which is convenient for workers to take and use for assembly on the engine. The assembling worker first takes the 8 valve spring lower seats 4 pushed out from the bottom of one of the storage tubes 2 and installs them one by one into the installation pit of the intake side valve spring lower seat 4, and then takes the 8 valve spring lower seats 4 pushed out from the bottom of the other storage tube 2 and installs them one by one into the installation pit of the exhaust side valve spring lower seat 4. In this way, the quantitative material removal and installation of the valve spring lower seat 4 are completed, and the valve spring lower seat 4 is effectively prevented from being missed or over-installed.

[0033] As another example,Figure 1 and Figure 2 As shown, there are several material stripping plates 3, the number of which is equal to the number of material storage tubes 2, and one material stripping plate 3 is provided below each material storage tube 2. It is used to precisely push the valve spring lower seats 4 stacked below the multiple material storage tubes 2 synchronously.

[0034] It also includes a slide 5 and a guide rail 6, which is arranged on the mounting base 1 along the front-to-back direction; the slide 5 is slidably arranged on the guide rail 6, and the front end of the slide 5 is connected to the rear end of several stripper plates 3, and then by driving the slide 5 to move back and forth on the guide rail 6, the stripper plates 3 can be pushed synchronously and accurately to the valve spring lower seat 4.

[0035] It also includes a mounting plate 11 and a bracket 12. Two brackets 12 are arranged on the mounting seat 1 at intervals along the left and right directions, and the mounting plate 11 is suspended on the two brackets 12; a number of storage tubes 2 are arranged on the mounting plate 11 at intervals, and by controlling the height at which the storage tubes 2 are installed on the mounting plate 11, the height of the several valve spring lower seats 4 stacked below is controlled, and the target number of valve spring lower seats 4 is selected.

[0036] More specifically, Figure 1 and Figure 2 As shown, it also includes a drive shaft 7, a connecting plate 8 and a return spring 9. The connecting plate 8 is arranged on the slide 5; the drive shaft 7 is slidably arranged on the mounting plate 11 along the front and rear directions, the rear end of the drive shaft 7 is connected to the connecting plate 8, and the front end of the drive shaft 7 is provided with a handle 71; the return spring 9 is sleeved on the drive shaft 7, and the two ends of the return spring 9 are respectively in contact with the connecting plate 8 and the mounting plate 11.

[0037] When implementing it specifically, Figure 1 and Figure 2 As shown, by pulling the handle 71, the drive shaft 7 is driven to move forward, and then the return spring 9 is compressed, and the slide 5 is driven to move forward on the guide rail 6. Then, the valve spring lower seats 4 under the storage tubes 2 are pushed out from under the storage tubes 2 through the plurality of material stripping plates 3, which is convenient for workers to take. Then, the handle 71 is released, and under the action of the return spring 9, the slide 5 is driven to move backward, and the plurality of material stripping plates 3 are moved backward to exit from under the storage tube 2. Then, the valve spring lower seats 4 in the storage tube 2 fall out of the storage tube 2 under the action of gravity and the counterweight block 22 and are stacked between the processing tube and the mounting seat 1. This reciprocating process makes it convenient for workers to quickly take a certain amount of valve spring lower seats 4. If too much or too little is loaded, it can be quickly judged, which greatly improves work efficiency.

[0038] More specifically, Figure 2As shown, a limiting screw 10 is provided on the connecting plate 8 along the front-to-back direction, and the limiting screw 10 is threadedly engaged with the connecting plate 8. The limiting screw 10 is perpendicular to the plate surface of the mounting plate 11. The limiting screw 10 is rotated to control the length of the limiting screw 10 extending out of the connecting plate 8. When the slide 5 is pulled forward by the handle 71 and the drive shaft 7, and then the part of the limiting screw 10 located between the connecting plate 8 and the mounting plate 11 abuts against the mounting plate 11, the drive shaft 7 and several material selection plates 3 cannot continue to move forward, thereby accurately controlling the position of several valve spring lower seats 4 after being pushed out from under the storage tube 2, so as to facilitate workers to take them.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
