During the assembly process, the application of oil to the rectangular ring is a detail that cannot be ignored. As a key sealing element in piston calipers, the quality of the oil application directly affects the sealing performance and durability of the piston calipers.
[0003] Traditional rectangular ring lubrication methods mostly rely on manual operation or simple mechanized equipment, which have many shortcomings. Manual lubrication is not only inefficient and difficult to control in terms of uniformity, but it is also easily affected by human factors, resulting in unstable lubrication quality. Although some mechanized lubrication equipment has improved lubrication efficiency to a certain extent, it often cannot achieve precise adjustment of the lubrication position, which may lead to poor lubrication effect and thus affect the sealing effect and overall performance of piston calipers.
[0004] During the oiling process, the atomized oil sprayed by the oil spraying components is prone to splashing, which not only easily pollutes the workshop environment, but is also easy for operators to inhale, causing harm to their bodies. Utility Model Content

[0016] In this invention, the combination of an oil spray valve, an adjusting device, and a splash guard enables the equipment to perform oiling work accurately and stably, while also providing splash protection. This not only greatly improves production efficiency but also minimizes oil pollution of the workshop environment or harm to the human body, enhancing the safety of the working environment and meeting the environmental protection requirements of modern industrial production.
[0017] In this invention, the oil injection valve includes a valve body and an extension rod extending into the workpiece, with the oil injection hole located on the extension rod. This design allows the oil injection valve to directly and accurately spray oil onto the rectangular ring, and also enables the oil injection valve to cooperate with the anti-splash cover to achieve the anti-splash effect of the equipment.
[0018] In this invention, the dynamic position adjustment of the splash guard is achieved through the setting of the control device. During the oiling process, the position of the splash guard can be adjusted in real time as needed to minimize the splashing of oil onto the outside of the workpiece during spraying. At the same time, it also enables the splash guard of this equipment to be flexibly adjusted according to the different oiling requirements of different workpieces, thereby enhancing the adaptability of the equipment.
[0019] In this invention, the design of the positioning seat enables the workpiece to be fixed stably and accurately, preventing the workpiece from moving or shifting during the oiling process, thereby improving the accuracy and consistency of the oiling; by controlling the cylinder to drive the connecting plate, the splash guard covers the opening on the top of the workpiece, minimizing the possibility of oil splashing onto the outside of the workpiece.
[0020] In this invention, the height adjustment module moves the injection valve up and down via an adjustment cylinder and mounting plate, while the rotation adjustment module rotates the injection valve via a rotation cylinder and mounting plate. Together, these two modules provide the injection valve with three-dimensional adjustment capabilities. This three-dimensional adjustment allows the injection valve to be precisely positioned on any part of the workpiece, significantly improving the accuracy, flexibility, and production efficiency of rectangular ring coating. Furthermore, this allows the equipment to be adapted to different coating requirements for piston calipers of varying sizes, thus expanding its application range.
[0021] In this invention, the fuel injection valve is vertically mounted on the mounting plate, ensuring the stability of the fuel injection valve in the vertical direction during installation and movement; the central axes of the extension rod and the rotary cylinder are on the same straight line, so that the extension rod can minimize the space it occupies when rotating, thereby reducing the inner diameter of the through hole and reducing the possibility of atomized oil splashing out from the through hole.
[0022] In this invention, the splash guard is fixed to the lower surface of the connecting plate, making their structure more compact; at the same time, when the control cylinder drives the connecting plate to adjust its height, the splash guard can better cover the top opening of the workpiece; the through hole and the through hole are on the same vertical line, ensuring that the extension rod can pass through them smoothly to extend into the workpiece for oiling.
[0023] In this invention, the control cylinder and the regulating cylinder are stably installed by setting up a mounting bracket.
[0024] In this invention, the sliding fit between the guide rod and the guide sleeve provides stable guidance and support for the height adjustment module; even if the oiling process is disturbed by external forces, the guide rod and the guide sleeve can effectively absorb and disperse these forces, preventing the mounting plate from shaking or shifting, thereby ensuring the stability and accuracy of the oiling work.
[0025] In this invention, the anti-collision bar is sleeved on the extension rod of the fuel injection valve, effectively providing an additional protective structure for the extension rod. During the oiling process, if the workpiece or other parts of the equipment accidentally collide with the extension rod, the anti-collision bar can absorb and disperse the collision force, preventing the extension rod from being damaged or deformed, thereby protecting the fuel injection valve and its precision components.
[0026] In this invention, the detachable connection design between the anti-collision bar and the mounting plate gives it a certain degree of versatility. When it is necessary to replace the oil injection valve or extension bar of different specifications, only the anti-collision bar of the corresponding size needs to be replaced, without the need to make major modifications to the entire oiling equipment.
[0027] In this invention, the crash bar is divided into an installation part and a mating part. The installation part is detachably connected to the assembly plate by threads and bolts, making the installation and disassembly of the crash bar simpler and faster, without the need for complicated tools or steps. The threaded and bolted connection method also provides stable connection strength, ensuring the stability and reliability of the crash bar during the oiling process. Attached Figure Description

[0039] like Figure 1-7As shown, a rectangular ring oiling device includes an oil spraying assembly 1 and an anti-splash assembly 2. The oil spraying assembly 1 includes an oil spraying valve 3 and an adjusting device 4 for adjusting the position of the oil spraying valve 3. The oil spraying valve 3 includes a valve body 31 and an extension rod 32 extending into the workpiece 8, with an oil spraying hole 33 disposed on the extension rod 32. The anti-splash assembly 2 includes an anti-splash cover plate 5, which has a through hole 51 for the extension rod 32 to pass through. Through the arrangement and cooperation of the oil spraying valve 3, the adjusting device 4, and the anti-splash cover plate 5, the device can perform oiling work accurately and stably, and has an anti-splash function. This not only greatly improves production efficiency, but also minimizes oil pollution of the workshop environment or harm to the human body, improving the safety of the working environment and meeting the environmental protection requirements of modern industrial production.
[0040] In this utility model, the oil injection valve 3 includes a valve body 31 and an extension rod 32 extending into the workpiece 8, with an oil injection hole 33 disposed on the extension rod 32. This design allows the oil injection valve 3 to directly and accurately spray oil onto the rectangular ring, and also allows the oil injection valve 3 to cooperate with the anti-splash cover 5 to achieve the anti-splash effect of this equipment.
[0041] In this embodiment, the extension rod 32 is disposed at the bottom end of the valve body 31, and the oil injection hole 33 is disposed at the bottom end of the extension rod 32. The extension rod 32 and the valve body 31 together form an oil passage. The valve body 31 is provided with an oil inlet 34 for supplying oil to enter the oil passage. The oiling operation of the oil injection valve 3 is achieved through the design and cooperation of the oil inlet 34, the oil passage and the oil injection hole 33.
[0042] In this invention, the anti-splash assembly 2 further includes a control device 6, which includes a control cylinder 61 and a connecting plate 62. The connecting plate 62 is connected to the piston of the control cylinder 61, and the control cylinder 61 drives the connecting plate 62 to adjust its position. The anti-splash cover 5 is fixed on the connecting plate 62. The control device 6 enables dynamic position adjustment of the anti-splash cover 5. During the oiling process, the position of the anti-splash cover 5 can be adjusted in real time as needed to minimize the splashing of oil onto the outside of the workpiece 8 during spraying. At the same time, it also allows the anti-splash cover 5 of this equipment to be flexibly adjusted according to the different oiling requirements of different workpieces 8, enhancing the adaptability of the equipment.
[0043] In this utility model, a positioning seat 7 is included for fixing a workpiece 8. An opening is provided on the top of the workpiece 8 for the assembly of a rectangular ring and for the oil spraying component 1 to perform oil spraying. The oil spraying component 1 and the anti-splash component 2 are both located above the opening. A control cylinder 61 drives a connecting plate 62 to adjust its height and causes the anti-splash cover 5 to cover the opening. The design of the positioning seat 7 enables the workpiece 8 to be fixed stably and accurately, preventing the workpiece 8 from moving or shifting during the oiling process, thereby improving the accuracy and consistency of oiling. By controlling the cylinder 61 to drive the connecting plate 62 to make the anti-splash cover 5 cover the opening on the top of the workpiece 8, oil splashes onto the outside of the workpiece 8 as much as possible.
[0044] In this utility model, the adjusting device 4 includes a height adjusting module 41 and a rotation adjusting module 42. The height adjusting module 41 includes an adjusting cylinder 411 and a mounting plate 412. The mounting plate 412 is connected to the piston of the adjusting cylinder 411. The rotation adjusting module 42 is mounted on the mounting plate 412, and the adjusting cylinder 411 drives the mounting plate 412 and the rotation adjusting module 42 to adjust the height. The rotation adjusting module 42 includes a rotating cylinder 421 and an assembly plate 422. The rotating cylinder 421 is fixed on the mounting plate 412, and the assembly plate 422 is fixed on the rotating platform 423 of the rotating cylinder 421. The valve body 31 of the fuel injection valve 3 is mounted on the assembly plate 422, and the rotating cylinder 421 drives the valve body 31 to adjust the height. 21 drives the assembly plate 422 and the fuel injection valve 3 to rotate; the height adjustment module 41 realizes the up and down movement of the fuel injection valve 3 through the adjustment cylinder 411 and the mounting plate 412, while the rotation adjustment module 42 realizes the rotation of the fuel injection valve 3 through the rotation cylinder 421 and the assembly plate 422; thus, the height adjustment module 41 and the rotation adjustment module 42 together give the fuel injection valve 3 the ability to adjust in three-dimensional space. This three-dimensional adjustment capability allows the fuel injection valve 3 to be accurately positioned at any position on the workpiece 8, which greatly improves the accuracy, flexibility and production efficiency of rectangular ring oiling; at the same time, it also makes this equipment applicable to different oiling requirements of piston calipers of different sizes, thereby expanding the scope of application of this equipment.
[0045] In this utility model, the fuel injection valve 3 is vertically mounted on the mounting plate 422, ensuring the stability of the fuel injection valve 3 in the vertical direction during installation and movement; the extension rod 32 and the rotating table 423 of the rotary cylinder 421 are both cylindrical, and their central axes are on the same straight line, so that the extension rod 32 can minimize the space it occupies when rotating, thereby reducing the inner diameter of the through hole 51 and reducing the possibility of atomized oil splashing out from the through hole 51.
[0046] In this invention, the splash guard 5 is fixed to the lower surface of the connecting plate 62, making their structure more compact. Simultaneously, when the control cylinder 61 drives the connecting plate 62 to adjust its height, the splash guard 5 can better shield the top opening of the workpiece 8. The connecting plate 62 is provided with a through hole 63 that penetrates its upper and lower surfaces, and a through hole 51 that penetrates the upper and lower surfaces of the splash guard 5. The through hole 51 and the through hole 63 are on the same vertical line, ensuring that the extension rod 32 can smoothly pass through the through hole 51 and the through hole 63 to extend into the workpiece 8 for oiling.

An opening is provided at the top of the clamp body for each component to be installed in the inner space. The shape and size of the splash guard 5 correspond to the shape and size of the opening of the clamp body, thereby achieving a better splash prevention effect.
[0048] In this utility model, a mounting bracket 10 is provided next to the positioning seat 7. The control cylinder 61 and the adjusting cylinder 411 are both fixed on the mounting bracket 10. The mounting bracket 10 enables the stable installation of the control cylinder 61 and the adjusting cylinder 411.

The sliding engagement between the guide rod 413 and the guide sleeve 414 provides stable guidance and support for the height adjustment module 41. Even if the oiling process is disturbed by external forces, the guide rod 413 and the guide sleeve 414 can effectively absorb and disperse these forces, preventing the mounting plate 412 from shaking or shifting, thereby ensuring the stability and accuracy of the oiling work.
[0050] In this utility model, a crash bar 9 is included, and an installation channel 91 is provided inside the crash bar 9, through which both ends of the crash bar 9 pass. The crash bar 9 is sleeved on the extension rod 32 of the fuel injection valve 3, and the area of the extension rod 32 where the fuel injection hole 33 is located passes through the installation channel 91 and protrudes from the bottom end of the crash bar 9. The crash bar 9 sleeved on the extension rod 32 of the fuel injection valve 3 effectively provides an additional protective structure for the extension rod 32. During the oiling process, if the workpiece 8 or other parts of the equipment accidentally collide with the extension rod 32, the crash bar 9 can absorb and disperse the collision force, preventing the extension rod 32 from being damaged or deformed, thereby protecting the fuel injection valve 3 and its precision components.
[0051] In this utility model, the anti-collision bar 9 is detachably connected to the mounting plate 422; the inner diameters of the through hole 51 and the through hole 63 are both set to correspond to the diameter of the anti-collision bar 9; the detachable connection design between the anti-collision bar 9 and the mounting plate 422 gives it a certain degree of versatility. When it is necessary to replace the oil injection valve 3 or the extension rod 32 of different specifications, only the anti-collision bar 9 of the corresponding size needs to be replaced, without the need to make major modifications to the entire oiling equipment.
[0052] In this utility model, the anti-collision bar 9 includes a mounting part 92 and a mating part 93. The mounting channel 91 is disposed within the mating part 93. The mounting part 92 and the assembly plate 422 are detachably connected by threads and bolts. The assembly plate 422 is provided with a horizontally arranged first screw hole 100. The mounting part 92 is provided with a horizontally arranged second screw hole 101 that passes through it. The first screw hole 100 and the second screw hole 101 correspond to and match each other. When the anti-collision bar 9 is installed, bolts are used to mate with the first screw hole 100 and the second screw hole 101. The mounting part 92 is located above the mating part 93. The mounting part 92 is provided with a notch 94, which is located above the mounting channel 91. The mounting channel 91 is vertically arranged, and when the extension rod 32 is engaged with it, the end of the valve body 31 near the extension rod 32 is located within the notch 94. The anti-collision bar 9 is divided into a mounting part 92 and a mating part 93. The mounting part 92 is detachably connected to the mounting plate 422 by threads and bolts. This makes the installation and removal process of the anti-collision bar 9 simpler and faster, without the need for complicated tools or steps.
