Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lubricating grease application, in particular to a lubricating grease application device for maintenance of casting machine mechanical equipment. Background Art
[0002] Grease is a thick, oily semi-solid substance used for the friction parts of machinery to lubricate and seal. It is also used on metal surfaces to fill gaps and prevent rust. It is mainly made of mineral oil (or synthetic lubricant) and a thickener. The main functions of grease are lubrication, protection and sealing. The vast majority of greases are used for lubrication, called anti-friction greases. Anti-friction greases mainly reduce mechanical friction and prevent mechanical wear. They also have a protective effect against metal corrosion and a sealing and dust-proof effect. Most greases are semi-solid substances with unique fluidity. When applying, the grease is squeezed out of the tube and applied to the location where lubrication is required.
[0003] However, the inner diameter of the extrusion tube is the same. When the surface area of the transmission parts to be lubricated is relatively large, the extrusion speed of the grease is limited by the inner diameter of the extrusion tube, resulting in a low extrusion speed. If the inner diameter of the extrusion tube is set larger and extruded and applied to parts with a small area, there may be excessive extrusion and waste. Therefore, we propose a grease application device for casting machine mechanical equipment maintenance. Utility Model Content
[0004] The utility model aims to provide a grease applying device for maintaining casting machine mechanical equipment. Before extruding the grease, the rotary cover is first rotated to adjust the distribution state of three extrusion tubes, so as to change the number of extrusion tubes connected to the inside of the extrusion barrel, realize the control of the grease extrusion speed, meet the grease extrusion and coating requirements of transmission parts of different sizes, and only one extrusion tube is connected to the inside of the extrusion barrel to avoid excessive grease extrusion from the transmission parts when the transmission parts are small, thereby solving the problems raised in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grease application device for maintenance of casting machine mechanical equipment, comprising an extrusion barrel, a screw cover and a rotary cover, one end of the extrusion barrel is an open structure, and the other end of the extrusion barrel is a sealing structure, the screw cover is connected to the outer ring of the open end of the extrusion barrel by screwing, the middle position of the screw cover can slidably penetrate a push rod inserted into the extrusion barrel, the end of the push rod located inside the extrusion barrel is fixed with a piston, and the outer ring of the piston is in contact with the inner wall surface of the extrusion barrel; the rotary cover is rotatably sleeved on the outer ring of the sealed end of the extrusion barrel, three equidistantly distributed extrusion tubes are connected to the outside of the rotary cover, the extrusion tubes are connected to the inner side of the rotary cover, and the extrusion tubes in the middle position are located at the center of the rotary cover, and the surface of the sealed end of the extrusion barrel is provided with four extrusion holes connected to the inside of the extrusion barrel, wherein three extrusion holes are horizontally distributed on the end surface of the extrusion barrel, and another extrusion hole is located above the extrusion hole in the middle position, and the spacing between adjacent extrusion holes is equal to the spacing between adjacent extrusion tubes.
[0006] By adopting the above technical solution, when the transmission component is relatively small and a slower extrusion speed is required to avoid waste, the rotary cover is rotated so that the extrusion tubes on both sides are not connected to the inside of the extrusion barrel, and only the extrusion tube in the middle position is used to extrude the grease at a low speed. When the transmission component is slightly larger or larger and a slightly faster or smoother grease extrusion speed is required, the rotary cover can be rotated to connect two or three extrusion tubes with the inside of the extrusion barrel, so that the grease can be extruded at a slightly faster or faster speed.
[0007] Optionally, eight magnets are evenly embedded and fixed inside the outer ring of one end of the extrusion cylinder and inside the outer ring of the rotating cover, and the magnets of the rotating cover and the magnets of the extrusion cylinder can be attracted to each other when they are aligned.
[0008] By adopting the above technical solution, when the rotary cover is rotated to adjust the outer extrusion cylinder to be aligned with the extrusion hole or completely misaligned, the magnet of the rotary cover can be adsorbed with the magnet of the extrusion cylinder to achieve the positioning purpose.
[0009] Optionally, the outer ring of the push rod is provided with a thread, and the outer ring of the push rod located outside the extrusion barrel is connected to a nut by means of a screw connection.
[0010] By adopting the above technical solution, when not in use, the nut can be rotated to a position that touches the outer surface of the screw cap, so that the push rod can be locked to push into the extruder barrel, thereby preventing the piston from being pushed and squeezing out the grease.
[0011] Optionally, a sealing ring is fixedly attached to the inner ring surface of the rotating cover of the outer ring of the extrusion barrel, and the extrusion tube is sealed by the sealing ring when it is aligned with the extrusion hole.
[0012] By adopting the above technical solution, when the extrusion tube is aligned with the extrusion hole, the sealing ring can seal the connection between the two.
[0013] Optionally, a push plate is welded and fixed to the end of the push rod, and the push plate is located at the end of the push rod outside the extrusion barrel.
[0014] By adopting the above technical solution, the push rod can be pushed by the push plate.
[0015] Optionally, two annular grooves are arranged around the inner ring of the rotating cover, and an annular block is arranged around the outer ring of the extrusion cylinder inside the annular groove. The annular block can rotatably abut against the annular groove to realize rotatable guide locking of the rotating cover.
[0016] By adopting the above technical solution, the purpose of rotatably locking the rotary cover on the outer ring of one sealing end of the extruder cylinder is achieved.

The technical solution of the present application is to arrange a rotatable rotary cover at the end of the extrusion barrel, three extrusion tubes are arranged on the surface of the rotary cover, and a plurality of extrusion holes are arranged at the end of the extrusion barrel. The extrusion tube located in the middle position is always connected with the interior of the extrusion barrel through the extrusion hole in the middle position. Before the grease is extruded and applied, it is possible to adjust one of the other two extrusion tubes to be connected with the extrusion barrel, or to make all three extrusion tubes connected with the interior of the extrusion barrel. Thus, by changing the number of extrusion tubes connected with the interior of the extrusion barrel, the grease extrusion speed can be controlled, the grease extrusion and application requirements of transmission parts of different sizes can be met, and the waste of grease can be avoided.
[0019] 2. The technical solution of the present application is to evenly embed and fix eight magnets inside the outer ring of the end of the extrusion barrel and the outer ring of the rotary cover. When the rotary cover is rotated to the outside of the extrusion tube and the extrusion hole to be misaligned or aligned, the position of the rotary cover and the extrusion tube can be positioned by the mutual adsorption of the magnets of the extrusion barrel and the magnets of the rotary cover.
[0020] 3. The technical solution of the present application is to connect a nut to the outer ring of the push rod by means of a screw connection. The nut can be rotated to adjust its position until it contacts the outer side of the nut cover. When there is no need to push the piston to extrude the grease, the position of the push rod and the piston can be locked. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-4 The utility model provides a technical solution: a grease applying device for maintaining casting machine mechanical equipment, comprising an extrusion barrel 1, a screw cover 2 and a rotary cover 4, one end of the extrusion barrel 1 is an open structure, and the other end of the extrusion barrel 1 is a sealing structure, grease can be loaded into the interior of the extrusion barrel 1, and the interior of the extrusion barrel 1 is prevented from being filled, so that the screw cover 2 is connected to the outer ring of the open end of the extrusion barrel 1 by screwing to seal the extrusion barrel 1, a push rod 3 inserted into the extrusion barrel 1 is slidably penetrated in the middle position of the screw cover 2, and a piston 31 is fixed at the end of the push rod 3 located inside the extrusion barrel 1, and the outer ring of the piston 31 is in contact with the inner wall surface of the extrusion barrel 1.
[0028] The surface of the sealed end of the extrusion barrel 1 is provided with four extrusion holes 11 connected to the inside of the extrusion barrel 1, three of which are horizontally distributed on the surface of the end of the extrusion barrel 1, and the other extrusion hole 11 is located above the middle extrusion hole 11. The middle extrusion hole 11 is located in the middle position of the end of the extrusion barrel 1. A push plate 32 is welded and fixed at the end of the push rod 3. The push plate 32 is located at the end of the push rod 3 outside the extrusion barrel 1. When the push rod 3 is pushed by the push plate 32, the piston 31 can be pushed, so that the grease inside the extrusion barrel 1 can be squeezed out from the extrusion hole 11 to the outside.
[0029] By adopting the above-mentioned method, the grease can be extruded at a very fast speed, and the extruded grease is not easily applied to the parts that need lubrication, so the rotary cover 4 is rotatably sleeved on the outer ring of the sealed end of the extrusion barrel 1, and three equidistantly distributed extrusion tubes 41 are connected to the outer side of the rotary cover 4, the extrusion tubes 41 are connected to the inner side of the rotary cover 4, and the extrusion tube 41 in the middle position is located at the center of the rotary cover 4, the spacing between adjacent extrusion holes 11 is equal to the spacing between adjacent extrusion tubes 41, and the extrusion hole 11 in the middle position will always remain aligned with the extrusion tube 41 in the middle position, so the rotary cover 4 can be rotated to adjust the three extrusion tubes 41 to a distribution state with an inclined angle of 45°, so that only the extrusion hole 11 in the middle position is aligned with the extrusion tube 41 in the middle position, and the extruded grease is only squeezed out from the extrusion tube 41 in the middle position, thereby realizing the grease application operation on small parts.
[0030] When the grease needs to be extruded slightly faster, the rotary cover 4 can be rotated to adjust the three extrusion tubes 41 to a vertical distribution state, so that only the middle extrusion hole 11 and the upper extrusion hole 11 are aligned with the middle extrusion tube 41 and the other extrusion tube 41. The extruded grease is only squeezed out from the middle position and one side extrusion tube 41, and the speed of extruding the grease is slightly faster, so that the grease application operation on slightly larger parts can be achieved.
[0031] When the grease needs to be extruded faster, the rotary cover 4 can be rotated to adjust the three extrusion tubes 41 to a horizontal distribution state, so that the middle extrusion hole 11 and the extrusion holes 11 on both sides are aligned with the middle extrusion tube 41 and the other two extrusion tubes 41. The extruded grease is squeezed out from the three extrusion tubes 41 at the same time, and the speed of grease extrusion is the fastest, thereby realizing the grease application operation on large parts.
[0032] Eight magnets 43 are evenly embedded and fixed inside the outer ring at one end of the extrusion cylinder 1 and the outer ring of the rotary cover 4. When rotated to any of the above three states, the magnets 43 of the rotary cover 4 and the magnets 43 of the extrusion cylinder 1 will be aligned and attracted to each other, thereby achieving the purpose of positioning the rotary cover 4.
[0033] A sealing ring 411 is fixedly attached to the inner surface of the rotating cover 4 of the outer ring of the extrusion barrel 1. When the extrusion tube 41 is aligned with the extrusion hole 11, the sealing ring 411 is used to seal, thereby ensuring the sealing effect when the extrusion tube 41 is aligned with the extrusion hole 11.
[0034] In addition, a thread is provided on the outer ring of the push rod 3, and the outer ring of the push rod 3 located outside the extruder barrel 1 is connected to a nut 33 by screwing. When the equipment is used, the nut 33 can be screwed to the outer surface close to the screw cover 2, which limits the push of the push rod 3 and prevents the piston 31 from being pushed and the grease from being squeezed out when the equipment is idle.
[0035] Two annular grooves 42 are arranged around the inner circle of the rotary cover 4, and an annular block 12 is arranged around the outer circle of the extrusion cylinder 1 inside the annular groove 42. The annular block 12 can rotatably abut against the annular groove 42 to achieve the purpose of guiding and locking the rotary cover 4 when rotating.
[0036] When in use, unscrew the screw cap 2 and pull out the piston 31, so that the grease can be loaded into the interior of the extrusion barrel 1 and the extrusion barrel 1 is prevented from being filled too full. Then, pull the push rod 3 to move the piston 31 to the inner surface position close to the screw cap 2, and then screw the screw cap 2 on the outer ring at the end of the extrusion barrel 1, and insert the piston 31 into the extrusion barrel 1. Since the grease is not fully filled in the extrusion barrel 1, the grease will not be squeezed out. When it is necessary to use a single extrusion tube 41 to extrude the grease, rotate the rotary cover 4 until the three extrusion barrels 1 are distributed at an angle of 45 degrees, so that the extrusion tubes 41 on both sides are not aligned with any of the extrusion holes 11 on the outside. At this time, only the extrusion tube 41 in the middle position is aligned with the extrusion hole 11 in the middle position and maintains communication with the inside of the extrusion barrel 1. The magnet 43 in the rotary cover 4 and the magnet 43 inside the end of the extrusion barrel 1 can achieve the purpose of positioning under the adsorption effect. Then, the push rod 3 can be pushed by the push plate 32 to make the piston 31 in the extrusion barrel. 1 is pushed inside, pushing the grease and pushing it from the extrusion hole 11 in the middle position into the extrusion tube 41 in the middle position, and then being pushed and extruded from the extrusion tube 41 to the transmission component where the grease needs to be applied; when a slightly higher extrusion speed is required, the rotary cover 4 can be rotated before extrusion, so that the three extrusion cylinders 1 are in a vertical distribution state, so that the extrusion cylinder 1 located on the outside is aligned with the single extrusion hole 11 distributed above, so that the two extrusion cylinders 1 can be kept in communication with the inside of the extrusion cylinder 1 through the two extrusion holes 11, and the magnet 4 in the rotary cover 4 can also be 3 and the internal magnet 43 at the end of the extrusion tube 1 are attracted to achieve the positioning purpose, and then the push plate 32 can push the push rod 3 to push the piston 31 inside the extrusion tube 1, pushing the grease and pushing it from the two extrusion holes 11 into the two extrusion tubes 41 connected thereto, and then pushing it from the two extrusion tubes 41 at a slightly higher speed to the transmission parts where grease needs to be applied; and when a higher extrusion speed is required, the rotary cover 4 is also rotated before extrusion, so that the three extrusion tubes 1 are in a horizontal distribution state, so that the two extrusion tubes on both sides are pushed. 1 is aligned with the extrusion holes 11 on both sides, so that the three extrusion barrels 1 can be kept connected to the inside of the extrusion barrel 1 through the three extrusion holes 11 respectively. Similarly, the positioning purpose can be achieved under the adsorption effect of the magnet 43 in the rotating cover 4 and the internal magnet 43 at the end of the extrusion barrel 1. After that, the push plate 32 can push the push rod 3 to push the piston 31 inside the extrusion barrel 1, and the grease can be pushed and pushed from the three extrusion holes 11 into the three extrusion tubes 41 connected thereto, and then pushed and squeezed from the three extrusion tubes 41 to the transmission parts that need to be greased at the maximum speed. After use, in order to avoid accidentally pushing the push plate 32 and the push rod 3, the nut 33 on the outer ring of the push rod 3 can be rotated to a position that contacts the outer surface of the screw cover 2, so that the push rod 3 cannot be pushed into the inside of the extrusion barrel 1 to achieve the locking purpose, and the grease will not be squeezed to avoid being accidentally squeezed out and causing waste.
