Description

Technical Field

[0001] This utility model relates to CNC lathes, specifically a combined dual-spindle CNC lathe. Background Technology

[0002] As a core piece of equipment in modern machining, the CNC lathe's processing efficiency and automation level directly impact production benefits. Traditional CNC lathes mostly employ a single-spindle structure, requiring multiple clamping and reversing operations on the workpiece during machining. Especially when machining both ends of the workpiece, manual adjustment or auxiliary equipment is necessary, leading to complex processes, long processing times, and frequent manual intervention. Furthermore, traditional equipment lacks integrated automatic unloading functionality, requiring manual removal and sorting of finished workpieces. This not only increases the operator's workload but also makes efficiency fluctuations or quality issues prone to occur due to human factors.

[0003] While some twin-spindle CNC lathes exist in the existing technology, their structures are mostly independent twin-spindle layouts with insufficient coordination between the spindles. Furthermore, the tooling system and feed device are not flexible enough, making it difficult to achieve continuous and efficient machining at both ends of the workpiece. At the same time, the automation level of existing equipment is still limited, especially in the unloading process, which still relies on manual operation or external sorting devices, resulting in limited overall production efficiency and high costs. Therefore, a combined twin-spindle CNC lathe is proposed. Utility Model Content

[0018] The present invention will now be further described in conjunction with the accompanying drawings.

[0019] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] See Figures 1-4 As shown, a combined dual-spindle CNC lathe includes a bed 1, a spindle assembly mounted on the bed 1, a feed device mounted on the bed 1, and a clamping device 2 mounted on the spindle assembly; characterized in that the feed device includes a spindle feed device 3 and a tool feed device 4, the spindle assembly includes a fixed spindle 5 fixed on the bed 1 and a movable spindle 6 fixedly mounted on the spindle feed device 3; the tool feed device 4 includes a transverse feed device 41 and a longitudinal feed device 42, the longitudinal feed device 42 is equipped with a tool bar 7, and the tool bar 7 is equipped with a plurality of cutting tools 71;

[0022] By combining the fixed spindle 5, the movable spindle 6, the tool rack 7, and the tool head 73 on a CNC lathe, the fixed spindle 5 and the tool rack 7 fixedly installed on the tool rack feed device 4 form a machining device, and the movable spindle 6 fixedly installed on the spindle feed device 3 and the tool head 73 form a machining device. The two groups work together to automatically complete the machining of both ends of the workpiece, thereby improving production efficiency, reducing manual labor intensity, and lowering labor costs.

[0023] The feed device is a servo feed device consisting of a servo motor 72 and a lead screw.

[0024] In one embodiment, the machine bed 1 is further included with a motor 72, a cutter head 73 that is connected to the motor 72, and a plurality of cutting tools 71 mounted on the cutter head 73; the motor 72 is used to drive the cutter head 73 to rotate for tool changing.

[0025] In one embodiment, it further includes an automatic feeding mechanism 8 disposed on the bed 1 for automatic feeding; the automatic feeding mechanism 8 includes a discharge channel 81 mounted on the bed 1, a conveying roller 82 mounted on the discharge channel 81, a conveyor belt 83 mounted on the conveying roller 82, and a feeding motor 9 that is drivenly connected to the conveying roller 82.

[0026] With the automatic unloading mechanism 8, after both ends of the workpiece are processed, the workpiece is automatically unloaded and automatically stacked into the material frame 91. The operator only needs to take out the workpieces stacked in the material frame 91.

[0027] In one embodiment, a material frame 91 is also included, which is installed on one side of the discharge channel 81 and communicates with the discharge channel 81. The material frame 91 is used to stack workpieces, making it convenient for operators to pick up the materials.

[0028] In one embodiment, it further includes a pusher cylinder 92 installed on the discharge channel 81 for pushing the workpiece to the material frame 91, and a pusher plate 93 installed on the pusher cylinder 92; the pusher cylinder 92 and the pusher plate 93 are used to push the workpiece on the discharge channel 81 into the material frame 91.

[0029] In one embodiment, it further includes a guide plate 94 installed in the discharge channel 81 to guide the movement of the workpiece and a material pipe 95 for guiding the workpiece onto the discharge channel 81.

[0030] The material pipe 95 is used to guide the workpiece to the discharge channel 81; the guide plate 94 is used to guide the workpiece as it moves with the conveyor belt 83.

[0031] When using this utility model: First, the long bar of workpiece material is inserted into the fixed spindle 5 from the rear of the fixed spindle 5. After one end of the workpiece material extends beyond the fixed spindle 5 and the clamping device 2 to a set length, it is clamped by the clamping device 2. At this time, the fixed spindle 5 can drive the spindle, the clamping device 2 and the workpiece material to rotate. The CNC system controls the tool feed device 4 to operate according to the set programming. When moving laterally, it is driven by the lateral feed device 41. When changing tools, it is driven by the longitudinal feed device 42 to move the tool rack 7 up and down to change tools.

[0032] After one end of the workpiece is processed, the spindle feed device 3 is controlled to drive the movable spindle 6 and the clamp 2 to move to the set position of the workpiece. Then, the clamp 2 is controlled to clamp the workpiece. At this time, the clamp 2 installed on the fixed spindle 5 releases the workpiece. Then, the spindle feed device 3 is controlled to move backward a set distance, that is, to pull the workpiece to move a set distance. Then, the clamp 2 on the fixed spindle 5 is controlled to clamp the workpiece. Then, the fixed spindle 5 and the movable spindle 6 are controlled to rotate synchronously. Then, the tool feed device 4 is controlled to drive the tool 7 to move, and the cutting tool 71 on the tool 7 is driven to cut the workpiece.

[0033] After the workpiece is cut off, the spindle feed device 3 drives the workpiece to rotate and moves according to the set program. The control motor 72 drives the cutter head 73 to rotate and switches the corresponding cutter to process the other end of the workpiece. At this time, the fixed spindle 5 also drives the workpiece to rotate, and the cutter feed device 4 drives the cutter 71 on the cutter head 7 to process the workpiece.

[0034] After both ends of the workpiece are machined, the spindle feed device 3 moves the workpiece to the material tube 95. Once the workpiece is inside the material tube 95, the clamp 2 is released, and the workpiece falls onto the conveyor belt 83 along the material tube 95. The unloading motor 9 drives the conveyor rollers 82, which in turn drive the conveyor belt 83, moving the workpiece. During this movement, the workpiece moves along the guide plate 94 to the pusher plate 93. Then, the pusher cylinder 92 is activated, driving the pusher plate to push the workpiece into the material frame 91.

[0035] Operators only need to periodically remove the finished workpieces from the material frame 91 and clamp the raw materials.

[0036] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
