This manual oiling method is difficult to control the amount of oil injected each time, and the operator needs to master certain skills, the operation efficiency is low, and the oiling quality is difficult to control. That is, the amount of oil injected by manual oiling is controlled by the operator's feel and experience, which is difficult to quantify and stabilize.
[0003] In summary, how to improve the effect of spring oil filling operation is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content
[0004] In view of this, an object of the utility model is to provide a spring oil filling assembly, which can effectively improve the effect of the spring oil filling operation.
[0005] Another object of the utility model is to provide an oil injector including the spring oil injection assembly.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A spring oil injection assembly, comprising:
[0008] An oil injection device is provided with a cavity, wherein a guide shaft, a piston and a piston rod are sequentially connected in the cavity, wherein the guide shaft, the piston and the piston rod can all be lifted and lowered in the cavity, wherein the outer periphery of the guide shaft is used for sleeve springs, wherein the outer periphery of the piston rod is sleeved with a compression spring, wherein a first elastic end of the compression spring abuts against a bottom of the piston, and a second elastic end of the compression spring abuts against a bottom of the cavity, wherein a first preset amount of oil is injected into the cavity;
[0009] A trigger switch is provided at the bottom of the oil injection device, and the piston rod is inserted into the bottom of the cavity to trigger or move away from the trigger switch;
[0010] An oil filling valve, whose injection port is connected to the oil channel of the oil filling device, and the oil channel is connected to the cavity. The triggered trigger switch is used to control the opening of the oil filling valve to spray a second preset amount of oil into the cavity so that the cavity is full of oil.
[0011] In one embodiment, the oil injection device is provided with an upper step surface for defining the upper stop position of the piston and a lower step surface for defining the lower stop position of the piston. When the piston is located at the lower stop position, the trigger switch is triggered, and when the piston is located at the upper stop position, the spring is in a state to be taken out or to be installed.
[0012] In one embodiment, a cover plate is provided on the top of the oil injection device, and the cover plate is provided with a through hole for passing the spring. The cover plate is used to scrape off excess grease on the surface of the spring so that the amount of oil brought out by each spring is the same.
[0013] In one embodiment, the oil output of the spring is the same as the second preset amount.
[0014] In one embodiment, the volume difference of the piston moving up and down is the same as the second preset amount, and the sum of the second preset amount and the first preset amount is the same as the volume of the cavity.

[0020] When using the spring oil filling assembly provided by the utility model, the spring can be sleeved on the outer periphery of the guide shaft, and then the operator presses the guide shaft downward so that the guide shaft pushes the piston and the piston rod to move downward, and the compression spring can be compressed synchronously when the piston rod moves downward. When the piston rod moves downward to trigger the trigger switch, the oil filling valve can be triggered to spray a second preset amount of oil into the cavity. After the oil is sprayed into the oil channel, it can enter the cavity, so that the amount of oil in the cavity originally filled with the first preset amount of oil increases, so that the cavity is filled with oil, so that the spring is immersed in the cavity, so that the grease is evenly attached to the spring. When the operator no longer presses the spring, the elastic force of the compression spring will push the piston rod upward, and at the same time, the piston and the guide shaft can be synchronously moved up to the initial position, so that the operator can take out the spring after oil filling.
[0021] The device realizes automatic oil filling operation on the spring through the oil filling valve, which helps to reduce the difficulty and intensity of the operation of the operator, and the oil filling efficiency of the spring is high.

[0031] 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.
[0032] The core of the utility model is to provide a spring oil injection assembly, which can effectively improve the effect of the spring oil injection operation. Another core of the utility model is to provide an oil injector including the spring oil injection assembly.
[0033] Please refer to Figures 1 to 4 .
[0034] This specific embodiment provides a spring oil injection assembly, including:
[0035] An oil injection device 1 is provided with a cavity, in which a guide shaft 11, a piston 12 and a piston rod 13 are connected in sequence, and the guide shaft 11, the piston 12 and the piston rod 13 can all be lifted and lowered in the cavity, the outer periphery of the guide shaft 11 is used to sleeve the spring 4, the outer periphery of the piston rod 13 is sleeved with a compression spring 17, the first elastic end of the compression spring 17 is against the bottom of the piston 12, the second elastic end of the compression spring 17 is against the bottom of the cavity, and a first preset amount of oil is injected into the cavity;
[0036] The trigger switch 2 is arranged at the bottom of the oil injection device 1, and the piston rod 13 is inserted into the bottom of the cavity to trigger or move away from the trigger switch 2;
[0037] The injection port of the oil filling valve 3 is connected to the oil channel 14 of the oil filling device 1, and the oil channel 14 is connected to the cavity. The triggered trigger switch 2 is used to control the opening of the oil filling valve 3 to spray a second preset amount of oil into the cavity so that the cavity is full of oil.
[0038] It should be noted that the cavity is pre-filled with a first preset amount of oil, and by triggering the trigger switch 2, the oil filling valve 3 sprays a second preset amount of oil into the cavity, thereby filling the cavity with oil. By filling the cavity with oil, the spring 4 is immersed in the cavity, so that the grease spraying on the spring 4 is more uniform, which helps to reduce the uneven oil spraying phenomenon of the spring 4. Moreover, by automatically spraying the spring 4 with oil through the oil filling valve 3, the oil filling efficiency of the spring 4 can be effectively improved, and the labor intensity of the operator can be reduced.
[0039] In actual use, the shape, structure, position, size, etc. of the oil filling device 1, the trigger switch 2 and the oil filling valve 3 can be determined according to actual conditions and actual needs.
[0040] When using the spring oil filling assembly provided by the utility model, the spring 4 can be sleeved on the outer periphery of the guide shaft 11, and then the operator presses the guide shaft 11 downward, so that the guide shaft 11 pushes the piston 12 and the piston rod 13 to move downward, and the compression spring 17 can be compressed synchronously when the piston rod 13 moves downward. When the piston rod 13 moves downward to trigger the trigger switch 2, the oil filling valve 3 can be triggered to spray a second preset amount of oil into the cavity, and the oil can enter the cavity after being sprayed into the oil channel 14, so that the amount of oil in the cavity originally filled with the first preset amount of oil increases, so that the cavity is filled with oil, so that the spring 4 is immersed in the cavity, so that the grease is evenly attached to the spring 4. When the operator no longer presses the spring 4, the piston rod 13 will be pushed upward by the elastic force of the compression spring 17, and at the same time, the piston 12 and the guide shaft 11 can be synchronously moved upward to the initial position, so that the operator can take out the spring 4 after oil filling.
[0041] The device realizes automatic oil filling operation on the spring 4 through the oil filling valve 3, which helps to reduce the difficulty and intensity of operation of the operator, and the oil filling efficiency of the spring 4 is high. Only by triggering the trigger switch 2 can the oil filling valve 3 be controlled to automatically spray oil to fill the spring 4. In addition, the device has a simple structure, low manufacturing cost, and is easy to use, and can be promoted for use.
[0042] In summary, the spring oil filling assembly provided by the utility model can effectively improve the effect of the oil filling operation of the spring 4.
[0043] In one embodiment, the oil injection device 1 is provided with an upper step surface 15 for defining the upper stop position of the piston 12 and a lower step surface 16 for defining the lower stop position of the piston 12. When the piston 12 is at the lower stop position, the trigger switch 2 is triggered. After the trigger switch 2 is triggered, the oil injection valve 3 can spray oil into the oil injection device 1. The structure is as follows: Figure 3 As shown; when the piston 12 is at the upper stop position, the spring 4 is in a state to be taken out or to be installed, that is, after the operator stops pressing the guide shaft 11, the compression spring 17 will push the piston rod 13 and the piston 12 to move up to the upper stop position, so that the end of the guide shaft 11 is close to the top of the oil injection device 1, thereby facilitating the removal of the spring 4 or facilitating the installation of the spring 4 on the guide shaft 11. The structure is as shown in FIG. Figure 4 shown.
[0044] It should be noted that when the device is performing the oil filling operation on the spring 4, it is only necessary to manually put the spring 4 on the guide shaft 11 and press the guide shaft 11 downward, and then the oil filling valve 3 can be automatically triggered, and then the oil filling valve 3 can be used to automatically spray the spring 4. In the original manual syringe oil filling, the oil filling amount of the spring 4 is controlled by the operator's feel and experience, which is difficult to quantify and stably control. The device can effectively solve the problem of manual syringe oil filling, and achieve the quantifiable oil filling amount of the spring 4 without the need for the operator to be experienced. Moreover, the structure of the device is simple, the manufacturing cost is low, and the operation efficiency is high.
[0045] In one embodiment, a cover plate 7 is provided on the top of the oil filling device 1, and the cover plate 7 is provided with a through hole for passing the spring 4, and the cover plate 7 is used to scrape off excess grease on the surface of the spring 4, so that the amount of oil brought out by each spring 4 is the same. That is, after the spring 4 is filled with oil in the cavity filled with oil, when the spring 4 is taken out, the excess grease on the surface of the spring 4 can be scraped off by the cover plate 7, so that the amount of oil brought out by the spring 4 is constant and meets the designed oil filling amount tolerance range of the spring 4.
[0046] In one embodiment, the oil amount brought out by the spring 4 is the same as the second preset amount, that is, the oil amount brought out by the spring 4 is the same as the amount of oil sprayed by the oil injection valve 3 each time, so as to ensure the oil injection effect of each spring 4.
[0047] In one embodiment, the volume difference of the piston 12 moving up and down is the same as the second preset amount, and the sum of the second preset amount and the first preset amount is the same as the volume of the cavity. The cavity can be set as a cylindrical structure to reduce the flow of grease, and the volume difference of the piston 12 moving up and down is the amount of oil injected into the spring 4 each time.
[0048] It should be noted that a sealing ring 18 can be sleeved on the outer periphery of the piston 12 to seal the periphery of the piston 12 and the cavity, thereby reducing the oil from seeping through the side of the piston 12 and distributing the oil to the upper or lower part of the piston 12. This can avoid excessive dispersion of the oil and help improve the up and down movement effect of the piston 12.
[0049] In one embodiment, the injection port and the oil passage 14 are connected via a hose 5 to ensure that the oil sprayed from the oil filling valve 3 is sprayed into the oil passage 14 through the hose 5 and then sprayed into the cavity through the oil passage 14 .
[0050] In one embodiment, the oil passage 14 is arranged horizontally, the guide shaft 11 is located at the upper part of the cavity, and the oil passage 14 is vertically connected to the upper part of the cavity. Figure 2 As shown, the oil injected from the oil injection valve 3 is directly injected into the spring 4.
[0051] In one embodiment, the oil injected by the oil injection valve 3 includes No. 10 machine oil.
[0052] It should be noted that machine oil is a type of lubricating oil, which is mainly used for lubrication of mechanical transmission. Machine oil is usually divided according to the viscosity of the oil, from No. 10 to No. 50, and the larger the number, the higher the viscosity. That is, the viscosity of No. 10 machine oil is relatively low, which is more convenient for the lifting and lowering movement of the guide shaft 11, the piston 12 and the piston rod 13. Of course, the oil can also be set to other types of oil, but it is necessary to ensure that the fluidity of the oil is better.
[0053] In one embodiment, a support member 6 is further included, and the oil injection device 1 and the oil injection valve 3 are both arranged on the support member 6, so that the device structure is more compact and occupies less space.
[0054] In addition to the above-mentioned spring oil filling assembly, the present invention also provides an oiler including the spring oil filling assembly disclosed in the above-mentioned embodiment. For the structures of other parts of the oiler, please refer to the prior art and will not be described in detail herein.
[0055] It should be noted that, in the first elastic end and the second elastic end mentioned in the present invention, the first and the second are only used to distinguish the difference in position, and there is no distinction between the order of precedence.
[0056] In addition, it should be noted that the orientation or position relationship indicated by "upper" and "lower" etc. in the present invention is based on the orientation or position relationship shown in the accompanying drawings, and is only for the convenience of simplifying the description and facilitating understanding, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0057] Each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referenced to each other. Any combination of all embodiments provided by the utility model is within the protection scope of this utility model and will not be described in detail here.

This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of the utility model.
