Description

Technical Field

[0001] The utility model relates to the technical field of lathe oil tanks, in particular to an improved lathe oil tank filtering device. Background Art

[0002] In the field of mechanical processing, lathes are essential metal-cutting equipment, and their stability and precision directly impact the quality of machined parts. Cutting fluid is an essential auxiliary material during lathe operation, effectively reducing cutting temperatures, minimizing tool wear, and improving surface quality. However, during the recycling process, cutting fluid gradually picks up impurities such as metal debris and oil sludge. If these impurities are not promptly removed, they can seriously affect the effectiveness of the cutting fluid and even damage the lathe equipment.

[0003] The reference patent name is a lathe oil tank filter device (publication number CN217567851U). The cutting fluid used on the lathe falls into the drainage groove, flows down from the oil outlet of the drainage groove to the coarse filter part, undergoes coarse filtration through the coarse filter part, and then settles in the sedimentation part. After fine filtration through the fine filter part, it flows into the filter chamber. When the filter chamber enters the oil storage chamber, it is filtered for the last time through the screen to completely remove impurities. The motor drives the oil pump to supply the cutting fluid in the oil storage tank to the lathe for use, forming a circulation, and removing impurities more cleanly. Moreover, the filter component is directly placed at the installation position and can be directly taken out as a whole for cleaning, which is convenient to clean.

[0004] Based on the above patent, the existing lathe oil tank filter device lacks a replacement structure. During specific filtration, the filter is easily clogged, and cleaning and replacement are more likely to affect the normal operation of the lathe. For this reason, the present utility model provides an improved lathe oil tank filter device. Utility Model Content

[0027] See also Figure 1-5The utility model provides a technical solution: an improved lathe oil tank filtering device, comprising an oil tank 1, a filtering mechanism 2 is provided at the upper end of the oil tank 1, and the filtering mechanism 2 includes: a sub-filter assembly 21, which is arranged at the upper end of the oil tank 1, and includes a connecting rod 214 fixed to the rear end of the oil tank 1, a T-shaped rail rod 215 is fixed to the upper end of the connecting rod 214, a T-shaped slot rod 211 is slidably mounted on the T-shaped rail rod 215, and a plurality of groups of frame boxes 212 are fixed at the front end of the T-shaped slot rod 211, and a filter screen 213 is installed on the inside of the frame box 212; a first transmission assembly 22, which is arranged at the front end of the oil tank 1, and is used to provide power for the horizontal propulsion of the sub-filter assembly 21; a second transmission assembly 23, which is arranged at one end of the first transmission assembly 22, and is used to push the sub-filter assembly 21 to move horizontally.

[0028] In this embodiment, the first transmission assembly 22 includes a mounting plate 221 fixed to the front end of the oil tank 1, and a motor 222 is fixedly installed at the front end of the mounting plate 221. The motor 222 rotates the semicircular plate 224 through the transmission shaft 223, and an L-shaped push rod 225 is integrally formed on one side of the semicircular plate 224. The front end of the oil tank 1 is rotatably connected to the rotating shaft 226, and a slotted plate 227 is fixed to the front end of the rotating shaft 226. The slotted plate 227 is provided with a positioning groove that engages with the semicircular plate 224 and the L-shaped push rod 225, and the positioning grooves are distributed in a circular array. The second transmission assembly 23 includes a gear 231 fixed on the rotating shaft 226, and a rack 232 that meshes with the gear 231 is fixed to the front end of the frame box 212. The motor 222 starts to rotate through the transmission shaft 223, driving The semicircular plate 224 connected to it rotates periodically, and the L-shaped push rod 225 cooperates with the slot plate 227. As the semicircular plate 224 rotates, the one-piece L-shaped push rod 225 on one side will periodically contact the slot plate 227 on the rotating shaft 226 rotatably connected to the front end of the oil tank. The slot plate 227 is provided with a plurality of positioning grooves matching the semicircular plate and the L-shaped push rod. These positioning grooves are distributed in a circular array to ensure that the L-shaped push rod can push the slot plate 227 to rotate along its rotation axis in turn. When the slot plate 227 is pushed to rotate by the L-shaped push rod 225, the rotating shaft 226 rotates accordingly, thereby driving the gear 231 to rotate. The gear 231 is engaged with the rack 232, so that the rotation of the gear 231 will be converted into horizontal movement of the rack 232.

[0029] In this embodiment, a support rod 3 is fixed to the rear end of the oil tank 1, and a filter inlet hopper 4 is fixed to one side of the upper end of the support rod 3.

A clamping strip 54 is integrally formed on the second base block 53, and a clamping slot block 55 for the clamping strip 54 to be plugged in is fixed to the upper ends of the T-slot rod 211 and the rack 232. An L-shaped rod 6 is fixed to one end of the oil tank 1, and a ladder block 7 is fixed to the upper end of the L-shaped rod 6. During the horizontal movement of the frame 212, the ladder block 7 squeezes the second base block 53, and the clamping strip 54 is pulled out of the slot hole from the clamping slot block 55, thereby completing the disassembly of the frame 212.

[0030] It is worth noting that the motor specifically adopts a stepping motor capable of forward and reverse rotation, so that the filtering structure can be reset.

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] During operation, when the oil in the oil tank 1 needs to be filtered, the motor 222 installed on the mounting plate 221 at the front end of the oil tank is started, and the motor 222 starts to rotate through the transmission shaft 223, driving the semicircular plate 224 connected thereto to rotate periodically, and the L-shaped push rod 225 cooperates with the slot plate 227. As the semicircular plate 224 rotates, the one-piece L-shaped push rod 225 on one side will periodically contact the slot plate 227 on the rotating shaft 226 connected to the front end of the oil tank. The slot plate 227 is provided with a plurality of positioning grooves that match the semicircular plate and the L-shaped push rod. These positioning grooves are distributed in a circular array to ensure that the L-shaped push rod can push the slot plate 227 along its rotation axis to perform small intermittent rotations in turn; when the slot plate 224 rotates, the L-shaped push rod 225 on one side will periodically contact the slot plate 227 on the rotating shaft 226 connected to the front end of the oil tank. When 27 is pushed to rotate by the L-shaped push rod 225, the rotating shaft 226 rotates accordingly, thereby driving the gear 231 to rotate. The gear 231 is engaged with the rack 232, so the rotation of the gear 231 will be converted into the horizontal movement of the rack 232, thereby pushing the entire filter assembly 21 to move horizontally along the T-shaped rail rod 215. The filter inlet hopper 4 is arranged above the oil tank 1, and is used to guide the oil to be filtered into the oil tank 1 and filtered through the filter assembly 21; in addition, an L-shaped rod 6 is fixed at one end of the oil tank 1, and a ladder block 7 is fixed at the upper end of the L-shaped rod 6. During the horizontal movement of the frame box 212, the ladder block 7 squeezes the second base block 53, and the card strip 54 is pulled out of the slot hole from the card slot block 55, thereby completing the disassembly of the frame box 212.
