Description

Technical Field

[0001] This utility model relates to the field of lubrication devices for countersinking equipment, and more particularly to an automatic countersinking grease dispenser. Background Technology

[0002] In the field of mechanical manufacturing, automated countersinking is a key process in the production of precision workpieces such as automotive parts and engineering machinery components. Its machining accuracy directly affects the fit and overall performance of the workpiece in subsequent assembly. To reduce frictional wear between the tool and the workpiece, minimize surface scratches, and extend tool life during machining, a grease distributor is needed to continuously and stably deliver grease to the machining area. Therefore, as a core auxiliary device in automated countersinking, the operational stability and functionality of the grease distributor have a significant impact on machining efficiency and product quality.

[0003] Currently, grease dispensers used in automated countersinking can achieve basic grease storage and directional delivery functions, meeting the needs of most conventional machining scenarios. However, there are still some technical aspects that need optimization in practical applications: On the one hand, because grease itself has high viscosity and relatively poor fluidity, existing dispensers are usually designed with a large internal cavity to ensure the amount of lubrication per cycle. However, the large cavity space can easily lead to poor grease flow within the cavity, especially when replenishing areas with insufficient grease filling. The residual grease is difficult to flow quickly and fully to the target area, which can easily result in uneven replenishment or omissions. On the other hand, the connectors between existing dispensers and external machining components are mostly fixed with bolts or multi-clamp structures. Disassembly and assembly require special tools and involve many steps, affecting replacement efficiency. At the same time, some connection structures are prone to loosening after long-term use, and when the connector is not connected to external components, there is a lack of an effective sealing structure, which may lead to accidental leakage of internal grease, resulting in resource waste or pollution of the machining environment.

[0004] In response to this technical problem, this application proposes an automatic countersunk hole machining grease dispenser. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic countersunk hole lubricant dispenser. This dispenser can achieve quantitative grease discharge through a fixed number of transmissions, solving the problem of insufficient filling of the processed area due to viscous residue and ensuring the lubrication needs of the countersunk hole. It also has the advantage of quick disassembly, simplifying the disassembly and assembly of the connector. After installation, it is automatically and securely fixed, and when not connected, it provides a one-way seal to prevent leakage, effectively improving the practicality and economy of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automatic countersunk grease dispenser includes a tank and a feed port. The feed port is located on the outer wall of the left side of the tank. A discharge port is fixedly connected to the right end of the tank. A connecting seat is fixedly connected to the right side of the tank. The connecting seat is connected to a connecting port via a fixing component. A fixing block is fixedly connected to the left end of the tank. A button is slidably connected to the upper left side of the fixing block. A screw is installed inside the tank. A scraper is fixedly connected to the right end of the screw. A pushing component is installed on the outer wall of the left side of the screw.

[0007] Furthermore, the fixing component includes a fixing shaft disposed on the outer wall of the left side of the connecting seat, the fixing shaft having a hole inside, a movable ball disposed inside the hole, the outer wall of the connecting seat having a groove, and a sliding cover slidably connected to the outer wall of the fixing shaft.

[0008] Furthermore, the pushing assembly includes a toothed roller fixedly connected to the lower side of the button, a gear meshing with the lower outer wall of the toothed roller, a transmission block slidably connected to the left outer wall of the gear, a lever rotatably connected to the right outer wall of the transmission block, an auxiliary plate rotatably connected inside the fixed block, the left outer wall of the transmission block being disposed inside the auxiliary plate, and the left outer wall of the screw slidably connected inside the fixed block.

[0009] Furthermore, a fixing ring is fixedly connected to the inner wall of the right side of the sliding cover, the outer wall of the fixing ring is located outside the hole, and a first spring is provided on the left side of the fixing ring, the outer wall of the first spring is located outside the sliding cover.

[0010] Furthermore, a bracket is fixedly connected inside the left side of the fixed shaft, and a sliding rod is slidably connected inside the bracket.

[0011] Furthermore, a fourth spring is sleeved on the upper outer wall of the toothed roller, and the outer wall of the fourth spring is disposed inside the fixed block.

[0012] Furthermore, a third spring is sleeved on the outer wall of the right side of the transmission block, and the outer wall of the third spring is located on the right side of the lever.

[0013] Furthermore, a baffle is fixedly connected to the left end of the sliding rod, a second spring is sleeved on the outer wall of the sliding rod, and a connection port is fixedly connected to the left end of the fixed shaft.

[0014] This utility model has the following beneficial effects: In this invention, the grease dispenser addresses the problem of insufficient grease filling in some machining areas due to the viscous and poor flowability of grease, and the large internal cavity that easily traps residue. This device effectively solves this problem. When grease needs to be replenished, the drive mechanism pushes the grease through the operation of relevant structures. The number of rotations of the transmission components remains consistent during each operation, ensuring a fixed distance the grease is pushed, thus achieving quantitative grease discharge. This quantitative discharge method precisely replenishes areas with insufficient grease, avoiding uneven replenishment or omissions, effectively guaranteeing lubrication needs during countersunk hole machining, and significantly improving the stability of lubrication performance.

[0015] This invention features a convenient quick-release design for the connecting components, significantly simplifying the assembly and disassembly process of the connector. When replacing or removing the connector, no complex tools or cumbersome operations are required; assembly and disassembly can be completed simply by sliding, greatly improving operational efficiency and saving time. Furthermore, after the connector is installed, the internal elastic structure automatically engages the fixing component with the connector seat, achieving a secure fixation and effectively preventing the connector from loosening. In addition, when no external objects are connected, the internal one-way sealing structure blocks the grease outflow channel, avoiding grease waste and contamination, further enhancing the practicality and economy of the device.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of an automatic countersunk grease dispenser, comprising a tank 1 and a feeding port 5. The feeding port 5 is located on the outer left side of the tank 1. A discharge port 3 is fixedly connected to the right end of the tank 1. A connecting seat 2 is fixedly connected to the right side of the tank 1. The connecting seat 2 is connected to a connecting port 4 via a fixing component. A fixing block is fixedly connected to the left end of the tank 1. A button 7 is slidably connected to the upper left side of the fixing block. A screw 10 is provided inside the tank 1. A scraper 8 is fixedly connected to the right end of the screw 10. A toothed roller 21 is provided on the outer left side of the screw 10. A gear 20 is meshed with the lower outer side of the toothed roller 21. A transmission block 18 is slidably connected to the outer left side of the gear 20. A lever 6 is rotatably connected to the outer right side of the transmission block 18. An auxiliary plate 9 is rotatably connected inside the fixing block. The outer left side of the transmission block 18 is located inside the auxiliary plate 9. The outer left side of the screw 10 is slidably connected inside the fixing block.

[0020] Specifically, the device is mainly used to deliver grease to the workpiece through a gear pump or other drive mechanism during the countersinking process, thereby achieving precise grease distribution. When the device is in use, the grease is pressurized and enters the cavity from the left feed port 5. The right discharge port 3 is sealed off. The workpiece is connected to the four interfaces on the front side to distribute and move the grease. Since most distributors have a large cavity inside, but the grease is relatively viscous and does not flow easily, a push plate is set up to discharge a fixed amount after the distribution is completed, which is used to replenish some areas where the filling grease is insufficient. Pressing button 7 will cause the toothed roller 21 to move downwards, thereby causing the side gear 20 to rotate. The transmission block 18 slides to the left of the gear 20, so the gear 20 will drive the transmission block 18 to rotate. The transmission block 18 can drive the auxiliary plate 9 to rotate in one direction. When the auxiliary plate 9 rotates, because the right side of the screw 10 slides inside the button 7, the rotation of the auxiliary plate 9 will drive the screw 10 to be threaded to the left, thereby pushing the grease out. After releasing, button 7 will rebound to the left and right of the fourth spring 22. At this time, the opposite direction of the gear 20 and the transmission block 18 will not drive the auxiliary plate 9 to rotate. When it is necessary to push the screw 10 to the right, the lever 6 can be moved to the right. The transmission block 18 will disengage from the auxiliary plate 9 and rotate in the opposite direction from the outside, thereby causing the screw 10 to unscrew. After releasing, the third spring 19 will push the transmission block 18 to slide to the left, thereby re-engaging. Because the number of rotations of the toothed roller 21, gear 20, and auxiliary plate 9 is consistent each time button 7 is pressed, the pushing distance of screw 10 is consistent, and the amount of grease dispensed is the same. Furthermore, different connectors are often required during use, so a quick-release design is incorporated, and internal grease will not leak out when not needed. By sliding the cover 14 to the left, the movable ball 15 inside the fixed shaft 11 loses the constraint of the side fixing ring 12 and can be easily removed. During installation, sliding the cover 14 and releasing it causes it to slide downwards under the action of the internal first spring 13, causing the fixing ring 12 to engage with the groove on the outer wall of the connector 2, thus preventing loosening. The diameter of the hole is slightly larger than the movable ball 15, but it will not allow it to come out. The internal baffle 17 and second spring 16 form a one-way channel, preventing internal grease from leaking out when the left side connection is not present.

[0021] Reference Figures 2-4A fixing ring 12 is fixedly connected to the inner wall of the right side of the sliding cover 14. The outer wall of the fixing ring 12 is located outside the hole. A first spring 13 is located on the left side of the fixing ring 12, and the outer wall of the first spring 13 is located outside the sliding cover 14. A bracket is fixedly connected to the inner left side of the fixed shaft 11, and a sliding rod is slidably connected inside the bracket. A fourth spring 22 is sleeved on the outer wall of the upper side of the toothed roller 21, and the outer wall of the fourth spring 22 is located inside the fixed block. A third spring 19 is sleeved on the outer wall of the right side of the transmission block 18, and the outer wall of the third spring 19 is located to the right of the lever 6. A baffle 17 is fixedly connected to the left end of the sliding rod, and a second spring 16 is sleeved on the outer wall of the sliding rod. A connection port 4 is fixedly connected to the left end of the fixed shaft 11.

[0022] Specifically, the fixing ring 12, which is fixedly connected to the inner wall of the right side of the sliding cover 14, has its outer wall located outside the hole and can fit into the groove on the outer wall of the connecting seat 2 to prevent the connector from loosening; the outer wall of the first spring 13 on its left side is sleeved on the outside of the sliding cover 14, which can drive the sliding cover 14 to reset. The bracket fixed inside the left side of the fixed shaft 11 can support the internal sliding rod to prevent it from shifting, and the sliding rod provides a foundation for the movement of subsequent components. The fourth spring 22, which is sleeved on the outer wall of the upper side of the toothed roller 21, is located inside the fixed block and can push the toothed roller 21 to spring back and reset after the button 7 is pressed. The third spring 19, which is sleeved on the outer wall of the right side of the transmission block 18, is located on the right side of the lever 6 and can push the transmission block 18 to reset after the lever 6 is turned, and re-engage the auxiliary plate 9. The baffle 17 fixed at the left end of the sliding rod, together with the second spring 16 sleeved on its outer wall, forms a one-way seal, which prevents grease leakage when there is no external connection and allows the channel to be opened when there is a connection; the connecting port 4 fixed at the left end of the fixed shaft 11 is used for directional delivery of grease.

[0023] Working principle: The grease enters the tank 1 through the left feed port 5 under pressure. At this time, the right discharge port 3 is closed. The grease is mainly distributed to external objects through the front connection port 4 via the connecting seat 2, which is fixedly connected to the tank 1. Because the grease is viscous and has poor fluidity, and conventional dispensers have large cavities that are prone to residue, the device uses a screw 10 and a scraper 8 to achieve quantitative replenishment: Pressing the button 7 on the left side of the fixed block will cause the toothed roller 21 on the left outer wall of the screw 10 to move downward. The toothed roller 21 meshes with the gear 20 on the lower side, thereby driving the gear 20 to rotate. The transmission block 18 on the left side of the gear 20 rotates with it, and drives the auxiliary plate 9 inside the fixed block to rotate in one direction. Because the left side of the screw 10 is slidably connected inside the fixed block, the rotation of the auxiliary plate 9 will drive the screw 10 to be threaded to the right. The scraper 8 then pushes the grease out of the connection port 4. After releasing the button, the fourth spring 22 on the upper side of the toothed roller 21 will cause the button 7 and the toothed roller 21 to spring back to their original positions. At this time, the gear 20 and the transmission block 18 rotate in opposite directions, and will not drive the auxiliary plate 9 to move, ensuring that each press only pushes the screw 10 once. When it is necessary to retract the screw 10 to the left, the lever 6 is moved to the right, which can disengage the transmission block 18 from the auxiliary plate 9. At this time, the external reverse rotation can drive the screw 10 to rotate out. After releasing the button, the third spring 19 on the right side of the transmission block 18 will push it to slide to the left and re-engage with the auxiliary plate 9 to reset. Since the number of rotations of the toothed roller 21, gear 20 and auxiliary plate 9 is fixed each time the button 7 is pressed, and the pushing distance of the screw 10 is consistent, a quantitative discharge of grease can be achieved to meet the replenishment needs of insufficient filling areas.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
