Description

Technical Field

[0001] This utility model relates to the field of applying grease to plugs, and more particularly to an oil dispensing mechanism. Background Technology

[0002] like Figure 9 As shown, Figure 9 Given the existing plug structure, the side of the plug has a coating surface, which needs to be coated with a layer of grease.

[0003] Current coating equipment is merely a pneumatic dispensing device that uses air to expel grease from the glue can onto the coating surface. However, this process lacks corresponding control measures. Specifically, the amount of liquid dispensed from the glue can is uncontrollable, resulting in a large amount of grease being wasted. Utility Model Content

[0004] To address the aforementioned problems, this invention provides an oil dispensing mechanism, which aims to solve the problem of uncontrollable grease output, resulting in significant waste of lubricating grease.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an oil dispensing mechanism, characterized in that it includes a dispensing head, a screw valve, and a storage component. The interior of the storage component is a cavity for containing lubricating grease. The outlet of the storage component is connected to the interior of the screw valve. The screw valve has a spiral shaft inside. The outer wall of the spiral shaft is provided with spiral patterns for pushing or drawing back the lubricating grease. The dispensing head is connected to the screw valve and has an outlet for the lubricating grease to flow out.

[0006] Because the plug is cylindrical and the coating surface is located on the side of the plug, the dispensing head has a pointed tip that contacts the coating surface, and the outlet is located on the edge of the pointed tip.

[0007] It also includes a quick-release assembly to maintain the connection between the screw valve and the rotary motor, while also enabling rapid assembly.

[0008] The quick-release assembly includes a first mounting base, a positioning plate, and a positioning pin. The rotary motor and the positioning plate are mounted on the first mounting base, and there is a positioning groove between the positioning plate and the first mounting base that is adapted to the screw valve. The positioning plate and the first mounting base are hinged together, and the positioning pin passes through the positioning plate and connects to the first mounting base. This opening method, which uses a pin and a positioning plate for hinge, improves the assembly efficiency of the entire product. During the entire assembly process, no other auxiliary devices are needed, making assembly simple.

[0009] In this embodiment, the positioning groove is formed by combining a first groove on the side of the first mounting base and a second groove on the inner side of the positioning plate.

[0010] The aforementioned rotary motor is the power source that drives the screw shaft to rotate.

[0011] The storage component is a rubber tube with a negative pressure port. The rubber tube has an outlet located at the bottom of the rubber tube. At the same time, the screw valve is located below the rubber tube. Under natural gravity, the grease flows into the screw valve. After the negative pressure port is connected to a negative pressure device, the grease in the rubber tube is attracted by the negative pressure and is stored in the rubber tube. When oil is dispensed, the negative pressure state inside the rubber tube changes to a normal pressure state, and the grease flows from the rubber tube into the screw valve.

[0012] Furthermore, due to environmental factors, the grease may solidify. The system also includes a heating component, which comprises a second mounting base and a heating rod. The second mounting base is connected to the first mounting base, and the heating rod is located inside the second mounting base. The heat generated by the heating rod is transferred to the first mounting base through the second mounting base.

[0013] Both the rotary motor and the rubber sleeve are fitted with a third mounting bracket to ensure the stability of their assembly.

[0014] It should be noted that it also includes a linear moving mechanism, and a mounting plate is provided on the output end of the linear moving mechanism. The first mounting seat is connected to the mounting plate. Since this embodiment is a dual-station oil dispensing, there are two dispensing heads, two screw valves, two material storage components, and two first mounting seats.

[0015] It also includes a worktable located below the dispensing head, on which an assembly spindle and pneumatic fingers are provided. The assembly spindle has an upward-opening cavity and an opening on the side of the assembly spindle. The clamping part of the pneumatic fingers clamps the plug inside the opening through the opening.

[0016] The beneficial effects of this utility model are:

[0017] This invention uses a spiral valve to control the amount of grease dispensed. The grease in the storage component flows into the spiral valve. The spiral shaft has spiral grooves with equal spacing between the grooves. Therefore, each section of the spiral grooves can deliver an equal amount of grease. Compared with traditional pneumatic delivery, this controllable feeding method can effectively control the amount of grease delivered, thereby avoiding the problem of large amounts of grease waste.

[0027] like Figure 1-9 As shown, an oil dispensing mechanism includes a dispensing head 1, a screw valve 2, and a storage component. The interior of the storage component is a cavity for containing grease. The outlet of the storage component is connected to the interior of the screw valve 2. The screw valve 2 has a spiral shaft 21 inside. The outer wall of the spiral shaft 21 is provided with spiral grooves 22 for pushing or sucking back the grease. The dispensing head 1 is connected to the screw valve 2 and has an outlet 1a for grease to flow out.

[0028] Since the plug 3 is cylindrical and the coating surface 31 is located on the side of the plug 3, the dispensing head 1 has a tip that contacts the coating surface 31, and the outlet 1a is located on the edge of the tip.

[0029] Backflow refers to the phenomenon where grease is pulled back into the storage component due to pressure changes when the screw shaft 21 rotates in the reverse direction. When using the screw shaft 21 to deliver grease, it is understood as the backflow phenomenon when the screw shaft 21 rotates in the reverse direction. This is very important for ensuring accurate delivery of grease and avoiding waste.

[0030] It also includes a quick-release assembly to maintain the connection between the screw valve 2 and the rotary motor, while also enabling rapid assembly.

[0031] The quick-release assembly includes a first mounting base 41, a positioning plate 42, and a positioning pin 43. The rotary motor 44 and the positioning plate 42 are mounted on the first mounting base 41, and there is a positioning groove between the positioning plate 42 and the first mounting base 41 that is adapted to the screw valve 2. The positioning plate 42 and the first mounting base 41 are hinged together. The positioning pin 43 passes through the positioning plate 42 and connects to the first mounting base 41. This opening method using the pin 45 and the positioning plate 42 for hinged connection improves the assembly efficiency of the entire product. During the entire assembly process, no other auxiliary devices are needed, and the assembly is simple.

[0032] In this embodiment, the positioning groove is formed by combining the first groove 41a on the side of the first mounting base 41 and the second groove on the inner side of the positioning plate 42.

[0033] The aforementioned rotary motor 44 is the power source for driving the rotation of the screw shaft 21, and the output end of the rotary motor 44 is connected to the screw shaft 21.

[0034] The storage component is a rubber cylinder 5 with a negative pressure port. The rubber cylinder 5 has an outlet located at the bottom of the rubber cylinder 5. At the same time, the screw valve 2 is located below the rubber cylinder 5. Under natural gravity, the grease flows into the screw valve 2. After the negative pressure port is connected to the negative pressure device, the grease in the rubber cylinder 5 is attracted by the negative pressure and is stored in the rubber cylinder 5. When oil is dispensed, the negative pressure state inside the rubber cylinder 5 changes to the normal pressure state, and the grease flows from the rubber cylinder 5 into the screw valve 2.

[0035] Furthermore, due to environmental influences, the grease may solidify. The system also includes a heating component, which comprises a second mounting base 61 and a heating rod 62. The second mounting base 61 is connected to the first mounting base 41, and the heating rod 62 is located inside the second mounting base 61. The heat generated by the heating rod 62 is transferred to the first mounting base 41 through the second mounting base 61.

[0036] Both the rotary motor 44 and the rubber sleeve 5 are fitted with the third mounting base 7 to ensure the assembly stability between the two.

[0037] It should be noted that it also includes a linear moving mechanism 8, and a mounting plate 9 is provided on the output end of the linear moving mechanism 8. The first mounting base 41 is connected to the mounting plate 9. Since this embodiment is a dual-station oil dispensing, there are two dispensing heads 1, two screw valves 2, two material storage components, and two first mounting bases 41.

[0038] It also includes a worktable 10 located below the dispensing head 1. The worktable 10 is provided with an assembly shaft 11 and a pneumatic finger 12. The assembly shaft 11 has an upward-opening cavity and an opening on the side of the assembly shaft 11. The clamping part of the pneumatic finger 12 clamps the plug 3 inside the opening through the opening.

[0039] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
