Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining center technology, specifically to a cooling device for a vertical high-speed machining center. Background Technology
[0002] A machining center is a highly automated CNC machine tool widely used in the field of machinery manufacturing. It integrates multiple machining functions such as milling, drilling, boring, and tapping, and is usually equipped with an automatic tool changer and a CNC system, enabling it to efficiently complete the precision machining of complex parts.
[0003] Chinese Patent CN22293359U discloses a machining center with a circulating cooling system, including a machining center body, a circulating cooling device, and a chip collection mechanism. In this invention, during machining, chips containing coolant are guided to the surface of a filter plate by a chip guide plate. The coolant contained in the chips drains downwards through drainage holes and returns to a water tank located at the bottom of the machining center body, allowing the coolant to be recycled. The filter plate uses a weighing sensor to determine the weight of the chips. When a set weight is reached, a cylinder extension shaft extends, driving a pusher plate to push the chips from the surface of the filter plate out of the chip discharge port, preventing chips from accumulating inside the machining center body. The chips pushed out by the pusher plate are collected in a chip collection box. The lower wall of the chip collection box is equipped with four sets of rollers, making it easy to pull away and replace empty chip collection boxes. A full chip collection box can be pushed away for centralized recycling without stopping the machine, thus avoiding any impact on machining efficiency.
[0004] However, in the above technical solution, the cylinder extension shaft extends only when the set weight is reached, driving the push plate to push the debris on the surface of the filter plate out of the chip discharge port, thus avoiding the accumulation of debris inside the machining center body. However, when using this device, the push plate needs to move along the filter plate in a straight line to push the metal debris. When the push plate moves, the small, thin metal debris is easily deformed and embedded in the mesh, making it difficult to remove. Utility Model Content

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0014] In this invention, during coolant recirculation filtration, the first filter screen can separate metal debris from the coolant. The movement of the push plate removes larger metal debris from the first filter screen, while the rotating roller and conveyor conveyor transport smaller metal debris embedded in the mesh of the first filter screen. At the same time, the cleaning brush can push them forward to prevent secondary compression and deformation when the push plate resets, thus avoiding poor coolant recirculation caused by filter screen clogging.

The cleaning brush 11 is arranged parallel to the push plate 8, and both ends of the cleaning brush 11 are connected to the push plate 8. The baffle 12 is connected to the machining center body 1, and the weight sensor 13 is connected to the baffle 12 in parallel. There are two multi-stage telescopic rods 14 arranged in parallel. One end of the multi-stage telescopic rod 14 is connected to the baffle 12, and the other end of the multi-stage telescopic rod 14 is connected to the support block 15. The number of elastic elements 16 corresponds to the number of multi-stage telescopic rods 14, and the elastic elements 16 are sleeved on the outside of the multi-stage telescopic rods 14. The elastic elements 16 are selected from, but are not limited to, springs. The recovery box is connected to the machining center body 1, and the recovery box has a feed port on the side of the machining center body 1 that is close to the machining center body 1. The feed port is connected to the machining center body 1.
[0024] In an optional embodiment, the transmission component 9 includes a first gear 17 and a mounting plate 18. The first gear 17 is connected to the rotating roller 10 and meshes with the rack 6 for transmission. The mounting plate 18 is connected to the push plate 8 and is connected to the rotating roller 10 on the opposite side of the mounting plate 18.
[0025] In an optional embodiment, the rotating roller 10 is composed of a roller body 19 and a sliding bar 20. The roller body 19 is provided with a plurality of limiting grooves 21. The number of sliding bars 20 corresponds to the number of limiting grooves 21. The sliding bars 20 are slidably connected to the limiting grooves 21.

[0026] In an optional embodiment, a support frame is connected inside the recycling bin, and a second filter plate 27 is placed on the support frame; the second filter plate 27 supports and filters the metal debris falling into the support frame, reducing the waste of coolant.
[0027] Example 3
[0028] like Figure 2 As shown, this utility model proposes a cooling device for a vertical high-speed machining center. Compared with Embodiment 2, this embodiment describes the detailed structure of the reflux assembly. The reflux assembly includes a reflux tank 22, a liquid storage tank 23, a water pump 24, and a circulation pump 25. Two reflux tanks 22 are symmetrically arranged and are located below the first filter screen plate 5. The liquid storage tank 23 is connected to the machining center body 1, and the water pump 24 is connected to the liquid storage tank 23. The water outlet of the water pump 24 is connected to the cooling pipe 3.

[0029] In an optional embodiment, the inlet end of the water pump 24 is connected to a filter screen 26; the filter screen 26 is used to prevent small metal debris from entering the water pump 24.
[0030] In summary, when this utility model is used, the workpiece is placed and clamped on the worktable of the machining center body 1. The machining center spindle 2 drives the cutting tool to perform machining on the workpiece. Machining will generate heat in the cutting tool. At this time, the water pump 24 can draw coolant from the storage tank 23. The coolant enters the cooling pipe 3 and is sprayed from the nozzle onto the cutting tool to cool it and prevent it from overheating. Metal chips generated during cutting will fall onto the machining center body 1. The guide plate on the machining center body 1 can guide the metal chips falling on both sides to fall above the first filter screen plate 5. The first filter screen plate 5 intercepts the metal chips, and the coolant can drip through the mesh into the return tank 22. After being drawn into the storage tank 23 by the circulation pump 25, the metal chips falling on the first filter screen plate 5 accumulate over time. When they reach a certain weight, they will accumulate. The compression of the elastic element 16 triggers the weight sensor 13, which in turn controls the telescopic device 7 to start. The piston rod of the telescopic device 7 extends and retracts, driving the push plate 8 to move along the first filter screen 5, pushing larger metal debris into the recycling bin. Simultaneously, the push plate 8 drives the mounting plate 18 to move synchronously. The first gear 17 meshes with the rack 6, driving the rotating roller 10 to rotate. The unblocking rod on the rotating roller 10 is inserted into the mesh of the first filter screen 5 to prevent smaller metal debris from deforming and embedding into the mesh, causing blockage. After separation, the coolant enters the return tank 22, and is drawn into the storage tank 23 by the circulation pump 25. When the cutting heat is low, the coolant can be cooled by the heat dissipation of the storage tank 23 and the return tank 22. The cooled coolant can be extracted by the water pump 24 for reuse.
