Description

Technical Field

[0001] The utility model relates to the technical field of machining centers, in particular to a high-stability water-cooling machining center. Background Art

[0002] A machining center generally refers to a CNC milling machine with a tool magazine. The biggest difference between a machining center and a CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changing device in one clamping to achieve multiple machining functions.

[0003] From the perspective of mechanical design, the stability and precision of high-stability water-cooled machining centers are crucial. In the design, factors such as the rigidity, strength, wear resistance, and fatigue resistance of the machine tool need to be considered to ensure that the machine tool can remain stable during long-term and high-intensity work. In addition, in order to achieve high-precision machining, the machine tool's transmission system, guide system, cooling system, etc. need to be precisely designed and manufactured.

[0004] When existing machining centers process objects, the tool and the workpiece will generate a lot of heat due to friction during the machining process. If there is no effective cooling measure, the heat accumulation may cause problems such as tool deformation, workpiece surface burns, and hardness changes. Most existing water spray heads are directly connected to the machining tool head. During machining, the tool head vibrates, causing the water spray head to vibrate, resulting in a decrease in the accuracy of the water spray and a reduction in the cooling effect.

[0005] Therefore, it is necessary to provide a high-stability water-cooling machining center to solve the above technical problems. Utility Model Content

[0006] The utility model aims to provide a high-stability water-cooling machining center, which can avoid direct connection between a water spray pipe and a machining cutter head, increase the stability of the water spray pipe during operation, and improve the cooling effect.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions: a high-stability water-cooled machining center, comprising a base, a column is fixedly installed on the side wall of the base, a top plate is fixedly installed on the top side wall of the column, a tool holder is slidably arranged at the bottom of the top plate, a processing tool head is rotatably connected to the bottom of the tool holder, a connecting block is fixedly connected to the top side wall of the tool holder, a shock absorber is fixedly installed at the bottom of one end of the connecting block away from the base, a first spring is fixedly connected between the two ends of the shock absorber, a water sprayer is fixedly connected to the bottom end of the shock absorber, a water sprayer is fixedly connected to a water spray pipe on the side of the water sprayer close to the processing tool head, a fixed block is slidably connected to the bottom of the side of the water sprayer close to the processing tool head, the bottom end of the water spray pipe passes through the top of the fixed block and is fixedly connected to the fixed block, a slide is fixedly connected to the side wall of the water sprayer close to the fixed block, the slide is fixedly installed inside the fixed block, the top and bottom of the slide are fixedly connected to second springs, and two second springs are fixedly connected to the inside of the fixed block.

[0008] By adopting the above technical solution, direct connection between the water spray pipe and the processing cutter head can be avoided, the stability of the water spray pipe during operation can be increased, and the cooling effect can be improved.

[0009] The utility model is further configured as follows: a limiting rod is fixedly installed inside one end of the fixed block close to the sprinkler, the limiting rod is slidably connected to the sliding plate, and the limiting rod is arranged inside the two second springs.

[0010] By adopting the above technical solution, the limiting rod assists the sliding of the sliding piece and limits the two second springs to prevent the second springs from being twisted.

[0011] The utility model is further configured as follows: a filter head is fixedly mounted on the side wall of the sprinkler away from the sprinkler pipe.

[0012] By adopting the above technical solution, the cooling water entering the sprinkler is filtered through the filter head to prevent solid impurities from entering the sprinkler.

[0013] The utility model is further configured as follows: a water tank is fixedly mounted on the side wall of the column, a connecting pipe is arranged inside the water tank, and one end of the connecting pipe passes through the water tank and is fixedly connected to the filter head.

[0014] By adopting the above technical solution, the water sprinkler draws the cooling water inside the water tank into the water sprinkler through the connecting pipe, and then sprays the cooling water through the water sprinkler pipe toward the machining cutter head to cool the machining cutter head.

[0015] The utility model is further configured as follows: a storage roller is provided on the side wall of the column, a connecting column is fixedly connected to the side wall of the storage roller, the connecting column is rotatably connected to the side wall of the column, a torsion spring is fixedly connected to the side wall of the connecting column, one end of the torsion spring away from the connecting column is fixedly connected to the column, and the connecting tube is wound around the storage roller.

[0016] By adopting the above technical solution, in order to adapt to the moving range of the tool holder and the processing tool head, the connecting pipe connecting the sprinkler and the water tank needs to have a certain length, and the torsion spring is stored by the storage roller. When the connecting pipe is pulled out, the storage roller rotates to compress the torsion spring. When the tool holder drives the connecting pipe to reset, the torsion spring returns to its original state and drives the storage roller to rotate to store the connecting pipe.

[0017] The utility model is further configured as follows: a water inlet is fixedly installed on the top of the water storage tank, a heating plate is fixedly installed inside the bottom of the water storage tank, and an electric heating wire is arranged inside the heating plate.

[0019] The utility model is further configured as follows: a positioning frame is fixedly installed on the top of the base.

[0020] By adopting the above technical solution, the processing range of the tool head is clearly defined through the positioning frame.

[0021] In summary, the utility model has the following beneficial effects: during the machining process of the machining center, the tool and the workpiece will generate a large amount of heat due to friction, and the machining cutter head needs to be cooled in time. During machining, in order to ensure that the water sprinkler and the water sprinkler pipe can accurately cool the machining cutter head, the tool holder and the water sprinkler are connected together through a connecting block, so that when the machining center moves the tool holder and the cutter head, the water sprinkler and the water sprinkler pipe can move synchronously and always keep consistent with the position of the machining cutter head, and the vibration energy generated by the tool holder and the machining cutter head during the machining process will be absorbed by the first spring between the connecting block and the water sprinkler and storage. When subjected to external force, the first spring will deform to absorb the external force. When the external force disappears, the first spring will return to its original state. The shock absorber is mainly used to suppress the shock when the first spring rebounds after absorbing the shock, and the second spring and the slide between the fixed block and the water sprayer are used to further buffer the vibration generated by the tool holder and the processing tool head to ensure the stability of the water spray pipe during the processing, so that the water spray pipe can accurately cool the processing tool head and improve the cooling effect. Through this device, the direct connection between the water spray pipe and the processing tool head can be avoided, the stability of the water spray pipe during the working process can be increased, and the cooling effect can be improved.
