Description

Technical Field

[0001] The present invention relates to the technical field of numerically controlled machine tools, in particular to a turning-milling compound machine tool capable of reverse drilling. Background Art

[0002] Turning-milling compound machine tools are core equipment in modern high-end manufacturing. They integrate the rotary processing capabilities of traditional lathes and the multi-directional tool feeding capabilities of milling machines. Their greatest feature is that they can complete multiple processes such as turning, milling, drilling, and tapping of complex parts (such as shafts, disks, and special-shaped parts) in one clamping, realizing "process concentration", which significantly reduces the number of clamping times, shortens processing time, and improves processing accuracy.

[0003] The patent application number CN202323640340.4 discloses a multi-milling cutter turning and milling compound machine tool, including a machine tool, a support frame is provided on one side of the machine tool, a milling mechanism is rotatably provided on the top of the support frame, a first slide rail is provided on one side of the support frame, a spindle bracket is slidably provided on the first slide rail, a workpiece clamp is rotatably provided on the top of the spindle bracket, a second slide rail is provided on one side of the first slide rail, a slide is slidably provided on the second slide rail, a third slide rail is provided on the top of the slide, and a milling cutter bracket is slidably provided on the third slide rail. Multiple milling processes can be performed on the workpiece at a single time, and there is no need to frequently replace the milling cutter, thereby improving the processing efficiency.

[0004] However, existing turning-milling compound machines capable of reverse drilling have significant shortcomings. First, there is a lack of a built-in automatic tool changing structure. When the reverse milling cutter is frequently damaged due to high-intensity reverse drilling, the operator needs to repeatedly stop the machine to intervene to replenish and position the tool. The processing process is frequently interrupted and the continuity is extremely poor, which seriously restricts the overall production efficiency of the equipment and is accompanied by safety risks of manual operation. Secondly, even if there is a simple tool magazine, its tool changing mechanism is often complicated or relies on an additional power source, making it difficult to achieve efficient and accurate tool switching. The degree of automation is low, and it is difficult to meet the needs of high-efficiency and high-flexibility processing.

[0005] In view of this, we propose a turning-milling machine tool with reverse drilling capability. Summary of the Invention

[0006] The object of the present invention is to provide a turning-milling compound machine tool capable of reversible drilling, which solves the problems raised in the above-mentioned background technology by integrating a tool changing device and utilizing an electric push rod to drive the single-axis linear motion of the transverse plate.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A turning and milling compound machine tool capable of reversible drilling comprises a turning and milling machine tool body, a tool changing device provided inside the turning and milling machine tool body and opposite to a tool turret, the tool changing device comprising a fixed portion, a driving portion provided inside the fixed portion, a traverse portion driven by the driving portion, a rotating disk provided inside the traverse portion, and a plurality of reverse milling cutters placed in the rotating disk;

[0009] The fixing portion includes a push rod and a plurality of guide blocks regularly distributed on the outer side of the ring wall of the push rod;

[0010] The driving part includes an electric push rod, a transverse plate driven by the electric push rod, a protruding rod arranged on the outer wall of the transverse plate, a tooth plate sleeved on the outside of the protruding rod, a rotating rod arranged on the inner side of the tooth plate, and rod teeth and clamping plates arranged on the left and right ends of the rotating rod, and a guide groove is opened on the top of the tooth plate;

[0011] In this setting, the transverse plate moves leftward, driving the convex rod to move along the guide groove, driving the tooth plate upward to rotate the rotating rod and change the angle of the splint;

[0012] The transverse moving part includes a placing platform and a limiting frame arranged on the top of the placing platform;

[0013] In this setting, the transverse plate slides inside the limit frame and drives the placement table to move after contacting the inside of the limit frame;

[0014] The rotating disk comprises a disk body, and a cam groove is provided in a convex ring on the left wall of the disk body;

[0015] In this setting, when the rotating disk moves left and right along with the placement table, the guide block inserts into the cam slot, driving the rotating disk to rotate in the reverse direction.

[0016] In the technical solution of the present invention, the fixing part also includes a bracket and two guide rails fixedly connected to the inner wall of the bracket by bolts. The push rod is welded and fixed to the horizontal plate on the left side inside the bracket, and the guide block and the push rod are integrally formed.

[0017] In the technical solution of the present invention, the electric push rod is fixedly connected to the outer wall of the bracket by bolts, the transverse plate is clamped and fixed to the end of the telescopic rod of the electric push rod, and the protruding rod and the transverse plate are integrally formed.

[0018] This setting allows the guide block to cooperate with the structure inside the rotating disk to make it rotate.

[0019] In the technical solution of the present invention, the longitudinal cross-section of the tooth plate is in an inverted L-shape, and the size of the guide groove is adapted to the protruding rod.

[0020] In the technical solution of the present invention, the rod teeth are clamped and fixed to the rotating rod, the rod teeth are engaged with the bottom end of the tooth plate, and the splint is clamped and fixed to the end of the rotating rod.

[0021] The above arrangement enables the back milling cutter placed on the turret in the turning-milling machine to be removed stably through the power of the electric push rod and the clamping plate.

[0022] In the technical solution of the present invention, a rotating groove for the rotating disk to rotate is opened inside the placing table, and a number of regularly distributed inner convex grooves are opened on the inner groove wall of the rotating groove of the placing table. A telescopic groove that runs through the upper and lower parts and is used to provide a moving range for the tooth plate is opened on the left side of the rotating groove inside the placing table, and the rotating rod is rotatably connected to the bottom end of the placing table.

[0023] In the technical solution of the present invention, the transverse movement part also includes two sliders arranged on the top surface of the placement table, the limit frame and the sliders are fixedly connected to the top surface of the limit frame by bolts, and the sliders are slidably connected to the outer side of the guide rail.

[0024] In the technical solution of the present invention, the transverse movement part also includes a limit bar slidably connected to the inside of the inner convex groove and several first springs welded to the outer wall of the limit bar, the other end of the first spring is welded to the inner groove wall of the inner convex groove, and the longitudinal cross-section of the limit bar is a right-angled trapezoid.

[0025] The above arrangement can adjust the position of the clamping plate before changing the position of the traverse portion by the power of the electric push rod, thereby changing the fixing strength of the bottom back milling cutter.

[0026] In the technical solution of the present invention, the disk body is rotatably connected to the inside of the rotating groove, and a number of regularly distributed slots that are adapted to the size of the reverse milling cutter are opened on the right wall of the disk body, and a number of regularly distributed matching grooves that are adapted to the size of the limit strip are opened on the outer ring wall of the disk body.

[0027] In the technical solution of the present invention, the rotating disk also includes a limiting rod slidably connected to the circular hole in the inner wall of the slot and a second spring welded to the inner wall of the limiting rod, and the other end of the second spring is welded to the hole wall of the circular hole in the inner wall of the slot.

[0028] The above arrangement cooperates with the guide block through the design of the cam groove, so that the rotating disk can rotate without an additional driving source to adjust the position of the back milling cutter.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. This reversible drilling turning-milling machine integrates a tool changer and utilizes an electric push rod to drive the single-axis linear motion of the traverse plate, enabling automatic switching between clamping and releasing the back-milling cutter. This completely eliminates the traditional operation mode that requires machine downtime and manual replacement of fragile back-milling cutters, significantly reducing tool change downtime, improving production efficiency, and eliminating the safety risks of manual operation.

[0031] 2. This reversible drilling turning-milling machine has a rotating disc designed with multiple slots that can be pre-installed with multiple reverse milling cutters. Through the left and right movement of the traverse unit, combined with the interaction between the fixed guide block and the specific cam groove on the disc body, the cutter disc can be precisely positioned and rotated during the return stroke. This allows the old cutter to be automatically recovered and the next new cutter to be accurately indexed and positioned to the waiting position during a tool change cycle, ensuring that the machine tool can continuously and automatically use multiple tools for processing. It is particularly suitable for working conditions where reverse milling cutters are easily damaged and need to be replaced frequently, greatly improving the continuity and automation of processing.

DETAILED DESCRIPTION

[0045] The following will provide a clear and complete description of the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0046] See also Figures 1-4 As shown, this embodiment provides a technical solution:

[0047] A turning-milling compound machine tool capable of reversible drilling includes a turning-milling machine tool body 100. A tool changing device 200 is provided within the turning-milling machine tool body 100 and opposite the tool turret. The tool changing device 200 includes a fixed portion 210, a driving portion 220 disposed within the fixed portion 210, a traverse portion 230 driven by the driving portion 220, a rotating disk 240 disposed within the traverse portion 230, and a plurality of reverse milling cutters 250 placed within the rotating disk 240.

[0048] Specifically, the fixing portion 210 includes a push rod 213 and a plurality of guide blocks 214 regularly distributed on the outer side of the ring wall of the push rod 213 .

[0049] Furthermore, the fixing portion 210 also includes a bracket 211 and two guide rails 212 fixedly connected to the inner wall of the bracket 211 by bolts. The top rod 213 is welded and fixed to the horizontal plate on the left side inside the bracket 211, and the guide block 214 is integrally formed with the top rod 213.

[0050] Furthermore, the bracket 211 is used to ensure the strength of the overall structure of the fixed part 210, the guide rail 212 is used to provide a sliding platform for the transverse part 230, and the top rod 213 is used to provide a fixed base point for the guide block 214. This setting allows the guide block 214 to rotate by cooperating with the structure in the rotating disk 240.

[0051] See also Figure 4-Figure 6 As shown, in this embodiment, the driving part 220 includes an electric push rod 221, a transverse plate 222 driven by it, a protruding rod 223 arranged on the outer wall of the transverse plate 222, a tooth plate 224 sleeved on the outside of the protruding rod 223, a rotating rod 225 arranged on the inner side of the tooth plate 224, and rod teeth 226 and a splint 227 arranged on the left and right ends of the rotating rod 225. A guide groove 2240 is provided on the top of the tooth plate 224. The transverse plate 222 moves to the left, driving the protruding rod 223 to move along the guide groove 2240, driving the tooth plate 224 to move up, allowing the rotating rod 225 to rotate, and changing the angle of the splint 227.

[0052] Specifically, the electric push rod 221 is fixedly connected to the outer wall of the bracket 211 by bolts, the transverse plate 222 is clamped and fixed to the end of the telescopic rod of the electric push rod 221, and the protruding rod 223 and the transverse plate 222 are integrally formed.

[0053] Furthermore, the longitudinal cross-section of the tooth plate 224 is in an inverted L-shape, and the size of the guide groove 2240 is adapted to the protruding rod 223 .

[0054] Furthermore, the rod teeth 226 are clamped and fixed to the rotating rod 225 , the rod teeth 226 are engaged with the bottom end of the tooth plate 224 , and the clamping plate 227 is clamped and fixed to the end of the rotating rod 225 .

[0055] Furthermore, after the electric push rod 221 is started, it drives the transverse plate 222 to move left inside the limit frame 232, drives the protruding rod 223 to move along the inside of the guide groove 2240, and drives the tooth plate 224 on its outer side to move upward, and then the meshing rod teeth 226 drives the rotating rod 225 to rotate, so that the splint 227 flips toward the reverse milling cutter 250 and contacts its outer wall, applying a force to its outer wall. This setting cooperates with the splint 227 through the power of the electric push rod 221, so that the reverse milling cutter 250 placed on the turret inside the turning and milling machine tool body 100 can be stably removed.

[0056] See also Figure 4-Figure 7 As shown, in this embodiment, the transverse moving portion 230 includes a placement table 231 and a limit frame 232 provided on the top thereof. The transverse moving plate 222 slides inside the limit frame 232 and drives the placement table 231 to move after contacting the inside thereof.

[0057] Specifically, a rotating groove 2310 is opened inside the placing table 231 for the rotating disk 240 to rotate, and a plurality of regularly distributed inner convex grooves 2311 are opened on the inner groove wall of the rotating groove 2310 of the placing table 231. A telescopic groove 2312 is opened on the left side of the rotating groove 2310 inside the placing table 231 to pass through from top to bottom and provide a moving range for the tooth plate 224. The rotating rod 225 is rotatably connected to the bottom end of the placing table 231.

[0058] Furthermore, the transverse movement portion 230 also includes two sliders 233 arranged on the top surface of the placement platform 231. The limit frame 232 and the sliders 233 are fixedly connected to the top surface of the limit frame 232 by bolts, and the sliders 233 are slidably connected to the outer side of the guide rail 212.

[0059] Furthermore, the transverse displacement portion 230 also includes a limit bar 234 slidably connected to the inside of the inner convex groove 2311 and a plurality of first springs 235 welded to the outer wall of the limit bar 234. The other end of the first spring 235 is welded to the inner groove wall of the inner convex groove 2311. The longitudinal cross-section of the limit bar 234 is a right-angled trapezoid.

[0060] Furthermore, during the continuous extension and retraction of the transverse plate 222, it can interfere with the inner wall of the limit frame 232, thereby driving the placement table 231 to move together. In addition, the slider 233 is used to ensure that the placement table 231 can be stably displaced, and the elastic force of the first spring 235 is used to push the limit bar 234 to move toward the outside of the inner convex groove 2311. This setting uses the power of the electric push rod 221 to adjust the position of the clamping plate 227 before changing the position of the transverse portion 230, thereby changing the fixing strength of the lowest back milling cutter 250.

[0061] See also Figures 4-10 As shown, in this embodiment, the rotating disk 240 includes a disk body 241, and a cam groove 2412 is opened in the convex ring on the left wall of the disk body 241. When the rotating disk 240 moves left and right with the placement platform 231, the guide block 214 is inserted into the cam groove 2412 to drive the rotating disk 240 to rotate in the opposite direction.

[0062] Specifically, the disk body 241 is rotatably connected to the inside of the rotating groove 2310, and a number of regularly distributed slots 2410 that are adapted to the size of the reverse milling cutter 250 are opened on the right wall of the disk body 241, and a number of regularly distributed matching grooves 2411 that are adapted to the size of the limit strip 234 are opened on the outer ring wall of the disk body 241.

[0063] Furthermore, the rotating disk 240 also includes a limiting rod 243 slidably connected to the circular hole in the inner wall of the slot 2410 and a second spring 242 welded to the inner wall of the limiting rod 243 , and the other end of the second spring 242 is welded to the hole wall of the circular hole in the inner wall of the slot 2410 .

[0064] Furthermore, the slot 2410 on the disk body 241 is used to provide a connection point for the reverse milling cutter 250, and the docking slot 2411 cooperates with the limit bar 234 to ensure the stability of the position of the disk body 241 after the rotation is completed. After the transverse displacement portion 230 is displaced left and right as a whole, the guide block 214 moves along the cam slot 2412, which can drive the rotating disk 240 to rotate, and the limit rod 243 cooperates with the second spring 242 to ensure the stability of the reverse milling cutter 250 when inserted into the slot 2410. This setting cooperates with the guide block 214 through the design of the cam slot 2412, so that the rotating disk 240 can rotate without an additional drive source to adjust the position of the reverse milling cutter 250.

[0065] Finally, it should be noted that the electric push rod 221 involved in the present invention is a universal standard part or a component known to those skilled in the art. Its structure and principle can be known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle space of this device, the electric push rod 221 is connected to the external power supply through a wire. The specific connection method should refer to the working principle of the present invention. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection methods are all well-known technologies in this field.

[0066] When the turning-milling compound machine tool capable of reversible drilling of the present invention is used, the displacement of the compound tool turret inside the turning-milling machine tool body 100 is first controlled to move the reverse milling cutter 250 on the tool turret to the bottommost slot 2410 in the disk body 241 of the rotating disk 240, and the pneumatic clamp of the tool turret is controlled to release the fixation of the reverse milling cutter 250;

[0067] Next, the electric push rod 221 in the driving unit 220 is controlled to drive the transverse plate 222 to move leftward inside the limit frame 232, driving the protruding rod 223 to move along the inside of the guide groove 2240, thereby driving the tooth plate 224 on its outer side to move upward, and then the meshing rod teeth 226 drive the rotating rod 225 to rotate, so that the clamping plate 227 flips toward the reverse milling cutter 250 and contacts the outer wall thereof, cooperating with the slot 2410, ensuring that the reverse milling cutter 250 can be stably located in the slot 2410;

[0068] Subsequently, the transverse plate 222 continues to retract and comes into contact with the left inner wall of the limit frame 232, driving the placement table 231 to move leftward. After the electric push rod 221 is fully retracted, the push rod 213 is inserted into the convex ring on the left wall of the plate body 241. During this process, the guide block 214 is inserted into the vertical groove of the cam groove 2412 and comes into contact with the front half of the wave groove of the cam groove 2412, driving the plate body 241 to rotate slightly as a whole.

[0069] Next, the electric push rod 221 is controlled to extend, driving the transverse plate 222 to move rightward within the limit frame 232. The protruding rod 223 is then driven to move within the guide groove 2240, driving the toothed plate 224 downward, driving the rotating rod 225 to rotate. After the clamping plate 227 is restored to its original position, the transverse plate 222 contacts the right side of the inner wall of the limit frame 232, driving the placement platform 231 to move rightward.

[0070] At this time, the guide block 214 moves along the second half of the wave groove of the cam groove 2412, and the drive plate 241 completes the angular rotation as a whole, and the end of the new back milling cutter 250 is inserted into the pneumatic clamp of the turret;

[0071] Afterwards, the turning and milling machine body 100 is controlled, the back milling cutter 250 is fixed by a pneumatic clamp, and the turret is operated to reset, and then the turning and milling operation of the workpiece is continued.

[0072] The foregoing descriptions of specific exemplary embodiments of the present invention are for purposes of illustration and description. These descriptions are not intended to limit the invention to the precise forms disclosed, and it is apparent that many variations and modifications are possible in light of the foregoing teachings. The exemplary embodiments have been selected and described for the purpose of explaining the specific principles of the invention and their practical application, thereby enabling those skilled in the art to make and utilize a variety of exemplary embodiments of the invention and various options and modifications.
