Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, and in particular to a multi-tool synchronous movement numerical control lathe with a back shaft system. Background Art

[0002] Numerical control machine tools include a control system and a machining center. The control system sends various control instructions to the machining center, enabling the machining center to automatically machine parts according to the requirements of the drawings. The existing machining centers do not have a back shaft system. For example, a five-axis synchronous movement machining structure machine tool provided by a Chinese invention patent (patent number: CN 116441957 A) machines the workpiece assembled in the workpiece chuck of the main shaft through five tool feeding assemblies, which cannot meet the machining of the back surface of parts or the machining of long workpiece materials, and the machining types are too limited, resulting in inability to adapt to the market environment. Therefore, improvement is needed. Summary of the Utility Model

[0003] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a multi-tool synchronous movement numerical control lathe with a back shaft system.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a multi-tool synchronous movement numerical control lathe with a back shaft system, which includes a machine table, a main shaft system arranged on the first side of the machine table, and a back shaft system arranged on the second side of the machine table. The main shaft system is configured with a main shaft chuck and a plurality of feed mechanisms arranged around the main shaft chuck. The back shaft system is set as one of a back surface main shaft mechanism, a back surface drilling mechanism, a back shaft tapping mechanism, or a long workpiece guiding mechanism;

The back shaft chuck is coaxially arranged with the main shaft chuck.

[0007] In a further technical solution, the back surface main shaft mechanism further includes a back shaft feed drive fixedly arranged on the back surface main shaft base. The back shaft connecting seat is slidably installed on the back surface main shaft base, and the back shaft feed drive slides the back shaft connecting seat to make the back shaft chuck feed towards or retreat from the main shaft chuck.

[0008] In a further technical solution, the back drilling mechanism includes a drilling base, a drilling slide seat slidably mounted on the drilling base, a drilling tool holder slidably mounted on the drilling slide seat, a drilling tool assembled on the drilling tool holder, and a multi-axis drilling feed drive mounted on the drilling base and used to drive the drilling slide seat to approach or move away from the spindle chuck.

[0009] In a further technical solution, the number of the drilling tools is set to be multiple, and the multiple drilling tools are assembled side by side on the drilling tool holder. The back drilling mechanism is further provided with a multi-axis tool changing drive, and the multi-axis tool changing drive is used to drive the drilling tool holder to slide up and down so that the corresponding drilling tool is coaxially aligned with the spindle chuck.

[0026] The following are only the preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly.

[0027] As Figures 1 to 8 shown, a multi-tool synchronous CNC lathe with a counter spindle system provided by the present utility model includes a machine tool 1, a main spindle system 2 provided on the first side of the machine tool 1, and a counter spindle system provided on the second side of the machine tool 1. The main spindle system 2 is configured with a main spindle chuck 20 and a plurality of feed mechanisms 21 arranged around the main spindle chuck 20.

[0028] The utility model includes a main spindle system and a back spindle system. Through the main spindle system, the needs of turning, milling, drilling, tapping, etc. on the side of parts in the market can be met. And through the back spindle system, the back of the workpiece can be further processed. Such a structural design is very ingenious, forming multiple working procedures to meet the diverse needs of users. Among them, the back spindle system can be configured as one of the back spindle mechanism 3, the back drilling mechanism 6, the back spindle tapping mechanism 5 or the long material guiding mechanism 4. For example, the back spindle mechanism 3 can be used in cooperation with the main spindle chuck 20 to alternately clamp parts. The back drilling mechanism 6 can drill the back of the part, and the back spindle tapping mechanism 5 can tap the back of the part. The long material guiding mechanism 4 can be used in cooperation with the main spindle chuck 20 to jointly clamp long materials.

[0029] When the back spindle system is configured as the back spindle mechanism 3, the back spindle mechanism 3 is provided with a back spindle base 30 installed on the machine table 1, a back spindle connecting seat 31 installed on the back spindle base 30, a back spindle driving mechanism 32 assembled on the back spindle connecting seat 31, a back spindle chuck 33 drivingly connected to the back spindle driving mechanism 32, and a braking system 34 for controlling the opening and closing of the back spindle chuck 33. The back spindle chuck 33 is coaxially arranged with the main spindle chuck 20.

[0030] The back spindle mechanism 3 further includes a back spindle feed drive 35 fixedly arranged on the back spindle base 30. The back spindle connecting seat 31 is slidably installed on the back spindle base 30. The back spindle feed drive 35 drives the back spindle connecting seat 31 to slide, so that the back spindle chuck 33 feeds towards or retreats from the main spindle chuck 20.

[0031] In practical applications, the back spindle driving mechanism 32 drives the back spindle chuck 33 to act. When the back spindle chuck 33 clamps the workpiece and the main spindle chuck 20 releases the workpiece, the other end face of the workpiece can be processed through the feed mechanism 21. For example, Figures 1 - 2 As shown, when the drilling is assembled on the feed mechanism 21, the front of the other end face of the part can be drilled, which is a process that the existing all-in-one machine cannot achieve.

[0032] When the back spindle system is configured as the back drilling mechanism 6, the back drilling mechanism 6 includes a drilling base 60, a drilling slide 65 slidably installed on the drilling base 60, a drilling tool holder 61 slidably installed on the drilling slide 65, a drilling tool 62 assembled on the drilling tool holder 61, and a multi-axis drilling feed drive 64 installed on the drilling base 60 and used to drive the drilling slide 65 to approach or move away from the main spindle chuck 20.

[0033] In a feasible embodiment, the number of the drilling cutters 62 is set to be multiple, and the multiple drilling cutters 62 are assembled side by side on a drilling cutter seat 61. The back drilling mechanism 6 is further provided with a multi-axis tool changing drive 63, and the multi-axis tool changing drive 63 is used to drive the drilling cutter seat 61 to slide up and down so that the corresponding drilling cutter 62 is coaxially aligned with the spindle chuck 20. By configuring multiple drilling cutters 62, holes of different specifications can be machined, and the multi-axis tool changing drive 63 can achieve rapid tool changing by driving the drilling cutter seat 61 to slide.

[0034] Among them, the multi-axis tool changing drive 63 can adopt a lifting module such as a lead screw nut mechanism or a cylinder, etc., and the multi-axis drilling feed drive 64 can be configured as a linear module.

[0035] When the back shaft system is configured as the long material guiding mechanism 4, the long material guiding mechanism 4 includes a long material base 40 fixedly installed on the machine table 1, a long material guiding seat 41 sequentially arranged on the long material base 40, and a material blocking member 42. The first end of the long material is clamped by the spindle chuck 20, and the second end passes through the long material guiding seat 41 and abuts against the material blocking member 42.

[0036] In specific applications, before machining, after clamping the first end of the long material by the spindle chuck 20, the second end of the long material is passed through the long material guiding seat 41 and abuts against the material blocking member 42 to complete the pre-assembly of the long material. Then, the long material is machined by a plurality of feed assemblies 21 arranged around the spindle chuck 20. Such a structural design can extend the clamping axis of the long material, play a role in supporting the second end (i.e., the tail end) of the long material, and avoid situations such as fracture or deviation of the long material due to unilateral force.

[0037] More specifically, the long material base 40 is further assembled with a material supporting block 43, and the material supporting block 43 is provided with a material supporting groove 430 extending along the length direction of the long material. The material supporting block 43 plays a further role in supporting and limiting the long material.

[0038] The long material base 40 is further provided with a material blocking lifting member 44, and the material blocking member 42 is assembled at the output end of the material blocking lifting member 44. During machining, the material blocking lifting member 45 pushes the material blocking member 42 to lift to achieve material blocking. After machining is completed, the material blocking lifting member 44 drives the material blocking member 42 to retract to its original position to facilitate the feeding of the long material.

[0039] The long material base 40 is assembled with a long material extension plate 45, and the long material extension plate 45 is assembled with a long material discharging module 46 and a material picking member 47. The long material discharging module 46 is used to drive the material picking member 47 to approach or move away from the long material guiding seat 41 so that the material picking member 47 picks up the long material in the long material guiding seat 41 and discharges it to a specified position.

[0040] The long material guiding mechanism 4 further includes a long material receiving rack 48 connected to the machine table 1 and a long material receiving box 49 installed on the long material receiving rack 48. The material taking part 47 unloads the long material processed in the long material tool holder into the long material receiving box 49 to realize automatic unloading.

[0041] When the back shaft system is configured as the back shaft tapping mechanism 5, the back shaft tapping mechanism 5 includes a tapping base 50 of the machine table 1, a tapping feed drive 51 fixedly installed on the tapping base 50, a tapping slide 52 slidably arranged on the tapping base 50, a tapping transmission component 53 assembled on the tapping slide 52, a tapping guide shaft 54 drivingly connected to the tapping transmission component 53, and a tapping tool 55 assembled at the end of the tapping guide shaft 54. The tapping tool 55 is coaxially arranged with the spindle chuck 20.

[0042] In specific applications, the tapping transmission component 53 drives the tapping guide shaft 54 to rotate, and the rotating tapping guide shaft 54 drives the tapping tool 55 to rapidly tap the back surface of the part. Among them, the tapping guide shaft 54 rotates coaxially with the spindle chuck 20, and rapid tapping is achieved through the speed difference between the two.

[0043] Among them, the structures of the tapping feed drive 51 and the multi-axis drilling feed drive 64 can be configured to be the same, and both are set as linear modules.

[0044] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
