Description

Technical Field

[0001] The utility model relates to the technical field of vertical CNC lathes, in particular to a vertical CNC lathe which is convenient for replacing turning tools. Background Art

[0002] Vertical CNC lathes can process products of various shapes, but the lathe tools need to be replaced frequently. Vertical CNC lathes are one of the most widely used CNC machine tools. They are mainly used for cutting and processing of inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer conical surfaces of arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads. They can also perform grooving, drilling, reaming, boring and boring. Different specifications of tools need to be replaced according to the processing of different products.

[0003] However, the connection between the turning tool and the lathe of the current vertical CNC lathe needs to be connected with screws and bolts. It takes a lot of time to disassemble and install the turning tool. In addition, due to the small specifications of the screws and bolts, parts may be lost during disassembly and installation, which affects the installation and replacement efficiency of the turning tool.

[0004] As disclosed in Chinese patent CN220050866U, a vertical CNC lathe that is easy to replace a turning tool is proposed. The rotating block is rotated to rotate the rotating rod, so that multiple groups of first bevel gears fixedly connected to the outside of the rotating rod rotate. Because the first bevel gear and the second bevel gear are meshed, the first bevel gear will drive the second bevel gear to rotate, thereby driving multiple groups of screw rods to rotate. Since the moving block is threadedly connected to the multiple groups of screw rods, the moving block can move accordingly at this time. The movement of the moving block allows the fixed plate to move, thereby achieving penetration or separation of the fixed plate from the fixed groove on the outside of the connecting seat, so that the connecting seat and the milling cutter can be disassembled and installed.

[0005] However, the tool replacement structure in the above-mentioned comparative document uses gear meshing to limit the tool, which may result in a situation where the limit is relatively loose when the tool is fixed, and some tools need to be rotated during use, which may cause the tool to loosen easily, affecting the cutting accuracy and processing safety.

[0006] For this reason, we urgently need to provide a vertical CNC lathe that is easy to replace turning tools. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0028] Embodiment 1:

[0029] A vertical CNC lathe for convenient tool replacement comprises a support leg 1, a body structure is mounted on the top of the support leg 1, a processing structure is mounted on the left side of the top of the body structure, and a cooling structure is mounted on the bottom of the body structure.

[0030] The processing structure includes an installation limit unit and a drive installation unit. The installation limit unit includes a threaded column 303. A card slot is provided at the bottom of the threaded column 303. A turning tool shaft 304 is connected inside the card slot.

[0032] Through the setting of the processing structure, the turning tool shaft 304 and the clamping plate 305 are clamped into the clamping groove at the bottom end of the threaded column 303, and then the turning tool shaft 304 can be limited to a certain extent by utilizing the threaded connection between the mounting tube 306 and the threaded column 303. Then, the rotating fixing bolt 307 can limit the connection between the threaded column 303, the turning tool shaft 304, and the mounting tube 306, thereby effectively preventing the turning tool from deviating during the processing and affecting the processing accuracy.

[0033] When installing the turning tool, the turning tool shaft 304 and the block 305 are placed into the slot opened at the bottom end of the threaded column 303, and then the mounting cylinder 306 is rotated to make it threadedly connected to the bottom end of the threaded column 303, thereby longitudinally limiting the turning tool shaft 304 and the block 305, and then the fixing bolt 307 is rotated to thread it into the threaded hole opened on the outer surface of the threaded column 303, the turning tool shaft 304, and the mounting cylinder 306, so that the rotation direction can be limited and fixed, thereby preventing the turning tool from shaking during the processing, thereby affecting the processing accuracy.

[0035] On the basis of the first embodiment, the fuselage structure includes a fuselage 101, a control panel 102 is installed on the right side of the front of the fuselage 101 near the top, a processing door 103 is installed near the left end of the top of the front of the fuselage 101, an observation window 104 is installed at the top of the middle of the front of the processing door 103, and an operating door 105 is installed at the bottom of the middle of the front of the fuselage 101. The bottom surface of the fuselage 101 is fixedly connected to the top of the support leg 1, the processing door 103 is hinged to the fuselage 101, the operating door 105 is hinged to the fuselage 101, the top surface of the fuselage 101 is connected to the mounting plate 301 near the left end, and the bottom of the processing bin on the top left of the fuselage 101 is connected to the bottom of the processing table 308.

[0036] The cooling structure includes a water tank 201, a support plate 202 is fixedly installed in the middle of the water tank 201, a collecting drawer 203 is connected to the top of the support plate 202, a water pump 204 is installed inside the water tank 201, a connecting pipe 205 is connected to the middle of the top of the water tank 201, a collecting bucket 206 is connected to the top of the connecting pipe 205, a delivery pipe 207 is connected to the back of the water tank 201, and a nozzle 208 is installed at one end of the delivery pipe 207 away from the water tank 201.

[0037] By setting up the cooling structure, starting the water pump 204 can spray the coolant inside the water tank 201 to cool down the processing part through the delivery pipe 207 and the nozzle 208, and at the same time, the processing debris can be rinsed and cleaned. After the cooling water mixed with the debris enters the water tank 201 through the filter holes at the bottom of the processing chamber, the debris is filtered by the filter net at the bottom of the collecting bin 203 and concentrated in the collecting bin 203. While completing the water circulation, it is convenient to clean the debris and centrally treat it.

[0038] When a turning tool is used to process a workpiece, the water pump 204 is started to pump the coolant in the water tank 201, so that the coolant can be sprayed on the turning tool and the processing parts of the workpiece for cooling through the delivery pipe 207 and the nozzle 208, and the processed chips can be rinsed and cleaned at the same time. The mixture of coolant and chips after cleaning enters the collection bucket 206 through a plurality of filtering holes opened at the bottom of the processing chamber, and then enters the collection bin 203 through the connecting pipe 205. The debris is filtered and collected by the filter net at the bottom of the collection bin 203, thereby allowing the coolant to circulate in water and facilitating the collection of debris for centralized treatment.
