Description

Technical Field

[0001] This utility model belongs to the field of burr machine technology, specifically, it relates to a burr machine with an automatic lubrication system. Background Technology

[0002] In the toy manufacturing industry, after injection molding, stamping, or die casting, toy parts made of plastics, alloys, and other materials often have burrs or flash remaining on their edges, affecting product safety and aesthetics. Therefore, toy deburring machines are widely used in post-processing steps such as deburring and trimming. Because toy parts are typically produced in large batches and require high precision, deburring machines need to run continuously for extended periods. The spindle and tool system are prone to wear under high-speed rotation and friction conditions, affecting processing accuracy and tool life. Currently, toy deburring machines mainly use manual lubrication or simple drip lubrication, which presents the following problems;

[0003] Currently, manual lubrication makes it difficult to accurately control the amount of oil, resulting in insufficient lubrication in some areas of the spindle or cutting tools, which exacerbates wear and may even affect the surface finish of toy parts. Plastic debris and dust in the toy production environment can easily mix into the lubricating oil, causing oil circuit blockage and requiring frequent shutdowns for cleaning, which affects production efficiency. Some automatic lubrication systems rely on electric or pneumatic pumps, which increases energy consumption and does not meet the toy industry's demand for low-cost and high-efficiency production.

[0004] To address the aforementioned problems, this application proposes a burr press with an automatic lubrication system. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a burr blower with an automatic lubrication system to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A burr with an automatic lubrication system includes a burr spindle, an oil injection cylinder rotatably mounted on the burr spindle, a tool mounting seat fixedly mounted at the bottom end of the burr spindle, one side of the oil injection cylinder being fixed to a mounting box, and an oil injection pipe being mounted on one side of the mounting box.

[0008] An active oil replenishment mechanism includes a piston block, which is slidably mounted on the inner wall of the oil filling cylinder. A rotating roller is fixedly mounted on the main shaft of the burr blower. A drive ring is movably sleeved on the outer side of the rotating roller. Two connecting rods are fixedly mounted at the bottom of the drive ring. The connecting rods are fixedly connected to the piston block. An isolation plate is fixedly mounted on the inner wall of the oil filling cylinder. The isolation plate cooperates with the piston block.

[0009] Preferably, the active oil replenishment mechanism further includes oil replenishment holes, with multiple oil replenishment holes respectively opened on the isolation plate and the piston block, and a slide rod movably connected to the oil replenishment hole. A plug plate is fixedly installed at the bottom end of the slide rod, and the plug plate cooperates with the oil replenishment hole.

[0010] The oil replenishment hole facilitates the replenishment and extraction of lubricating oil, and the plug plate seals the oil replenishment hole to facilitate discharge.

[0011] Preferably, a stop is fixedly installed at the top of the slide rod, and multiple top springs are fixedly installed at the top of both the piston block and the isolation plate, with the top springs fixedly connected to the bottom of the corresponding stop.

[0012] By setting up the stop block and the top spring, the stop block can push and pull the plug plate through the slide rod, so that the plug plate keeps in contact with the oil filling hole, thus forming a one-way oil guiding effect.

[0013] Preferably, the rotating roller has a circulation groove, and two sliders are slidably connected to the inner wall of the circulation groove. The sliders are fixedly connected to the inner side of the drive ring.

[0014] The rotating roller is connected to two sliders through a circulation groove, which enables the drive ring to move up and down.

[0015] Preferably, a filter box is slidably connected to the inner wall of the mounting box, a filter screen is fixedly installed on the inner wall of the filter box, the filter screen cooperates with the oil injection pipe, and a cover plate is fixedly installed on the top of the filter box, the cover plate cooperates with the mounting box.

[0016] The filter screen inside the filter box facilitates the filtration of oil injected through the oil filling pipe. Furthermore, the sliding connection between the filter box and the mounting box allows for easy disassembly of the filter box and cleaning of the filter screen.

[0017] Preferably, the bottom of the oil injection cylinder is equipped with multiple oil distribution pipes, and valves are installed on the oil distribution pipes.

[0018] The oil distribution pipes facilitate automatic oil replenishment to various parts of the burr press, which is controlled by valves.

[0019] In summary, the technical effects and advantages of this utility model are as follows:

[0020] 1. Spindle-driven automatic oil replenishment mechanism

[0021] The lubrication system is directly driven by the rotation of the burr spindle, eliminating the need for an additional motor or hydraulic pump. This method is energy-efficient and highly effective. The spindle drives the rotating rollers, and through a mechanical structure of a circulation groove and a slider, the rotational motion is converted into the reciprocating motion of the drive ring, which in turn pushes the piston block to draw in and discharge oil.

[0022] 2. One-way valve type oil replenishment structure

[0023] The combination of oil replenishment hole, plug plate, and top spring forms a one-way valve structure, ensuring that the lubricating oil can only flow in one direction and preventing backflow. When the piston block moves up (oil discharge): the oil pressure pushes open the plug plate, and the lubricating oil enters the oil distribution pipe through the oil replenishment hole. When the piston block moves down (oil suction): the negative pressure sucks open the plug plate on the isolation plate and draws new oil from the oil injection pipe, thus realizing automatic oil replenishment.

[0024] 3. Modular and detachable filtration system

[0025] Featuring a sliding filter box and screen, it can be easily disassembled and cleaned, preventing oil passage blockage. The cover design allows for quick and easy opening, enabling maintenance without complicated tools.

[0026] 4. Multi-channel oil distribution pipe + valve control

[0027] Multiple oil distribution pipes can supply oil to different lubrication points simultaneously, improving lubrication efficiency. Valves can adjust the flow rate of each oil circuit to meet the lubrication needs of different parts.

[0028] 5. Integrated structural design

[0029] The oil filling cylinder is directly sleeved on the spindle, serving as both a lubrication reservoir and an auxiliary spindle positioning chamber, reducing additional space occupation. The mounting box integrates filtration and oil inlet functions, resulting in a compact structure. Attached Figure Description

An isolation plate 4 is fixedly mounted on the inner wall of the oil filling cylinder 2. The isolation plate 4 cooperates with the piston block 51.

[0039] Reference Figure 2 and Figure 3 The active oil replenishment mechanism 5 also includes oil replenishment holes 57. Multiple oil replenishment holes 57 are respectively opened on the isolation plate 4 and the piston block 51. A slide rod 58 is movably connected to the oil replenishment hole 57. A plug plate 59 is fixedly installed at the bottom end of the slide rod 58. The plug plate 59 cooperates with the oil replenishment hole 57. A stop block 510 is fixedly installed at the top end of the slide rod 58. Multiple top springs 511 are fixedly installed at the top of the piston block 51 and the isolation plate 4. The top springs 511 are fixedly connected to the bottom of the corresponding stop blocks 510. The oil replenishment holes 57 facilitate the replenishment and extraction of lubricating oil. The plug plate 59 closes the oil replenishment holes 57, facilitating discharge. The stop block 510 and the top springs 511 allow the stop block 510 to push and pull the plug plate 59 through the slide rod 58, keeping the plug plate 59 in contact with the oil replenishment hole 57, thus forming a one-way oil guiding effect.

[0040] Reference Figure 4 The rotating roller 52 has a circulation groove 55. Two sliders 56 are slidably connected to the inner wall of the circulation groove 55. The sliders 56 are fixedly connected to the inner side of the drive ring 53. The rotating roller 52 can drive the drive ring 53 to move up and down through the circulation groove 55 and the two sliders 56.

[0041] Reference Figure 2A filter box 8 is slidably connected to the inner wall of the mounting box 7. A filter screen 9 is fixedly installed on the inner wall of the filter box 8. The filter screen 9 cooperates with the oil injection pipe 6. A cover plate 10 is fixedly installed on the top of the filter box 8. The cover plate 10 cooperates with the mounting box 7. The filter screen 9 in the filter box 8 can facilitate the filtration of the oil injected by the oil injection pipe 6. At the same time, the sliding connection between the filter box 8 and the mounting box 7 makes it easy to disassemble the filter box 8 and clean the filter screen 9.

[0042] Reference Figure 2 The bottom of the oil filling cylinder 2 is equipped with multiple oil distribution pipes 11, and valves 12 are installed on the oil distribution pipes 11. The oil distribution pipes 11 facilitate automatic oil replenishment to various positions of the burr press, and are controlled by the valves 12.

[0043] Working principle: During operation, the rotating burr spindle 1 drives the rotating roller 52 to rotate. The rotating roller 52 is slidably connected to two sliders 56 through the circulation groove 55, thereby driving the drive ring 53 to move up and down. The drive ring 53 drives the piston block 51 to move up and down through the connecting rod 54. When the piston block 51 moves up and down, it squeezes or sucks the space between the piston block 51 and the isolation plate 4. When the piston block 51 moves upward, it squeezes the space between the piston block 51 and the isolation plate 4. Under high pressure, the oil between the piston block 51 and the isolation plate 4 is forced downward by the stop plate 59 on the piston block 51, thereby opening the oil filling hole 57 on the piston block 51 and allowing the oil to be discharged. The oil is injected and lubricated at various locations through the oil distribution pipe 11. When the piston block 51 moves downward, a negative pressure state is created in the space between the piston block 51 and the isolation plate 4. The plug plate 59 on the isolation plate 4 opens under the action of the pressure difference between the upper and lower parts, and the space above the isolation plate 4 is sucked up, thereby extracting the oil in the oil injection pipe 6 and replenishing the space between the piston block 51 and the isolation plate 4. At the same time, the filter screen 9 in the filter box 8 in the mounting box 7 can facilitate the filtration of the oil injected into the oil injection pipe 6. The sliding connection between the filter box 8 and the mounting box 7 makes it easy to disassemble the filter box 8 and clean the filter screen 9.
