Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, and in particular to a special machine tool with combined turning and milling functions. Background Technology

[0002] With industrial development, parts with complex structures require more and more processing steps. Traditional processing methods typically use multiple machines to process different steps separately. This traditional processing method has the following significant drawbacks: 1. The dispersed process leads to an increase in the number of clamping operations: This not only prolongs the production cycle, but also significantly reduces the positional accuracy of the machined surface due to the accumulation of errors from multiple positioning operations.

[0003] 2. Increased number of equipment: More operators are needed, increasing production area and transportation workload, thereby driving up management and operating costs.

[0004] 3. Low production efficiency: Although the equipment is relatively simple to adjust and maintain, the overall production efficiency is low, making it difficult to meet the needs of large-scale, high-precision production and greatly affecting the processing efficiency of products.

[0005] It is evident that the existing technology, which relies on multiple machines for repeated clamping, not only increases the complexity of production but also limits the improvement of processing accuracy and production efficiency. Summary of the Invention

[0006] To solve the above-mentioned technical problems, this invention proposes a composite machine tool with strong processing capabilities.

[0007] A special-purpose machine tool with combined turning and milling functions includes a machine base, a worktable, a first machining mechanism, a second machining mechanism, and a third machining mechanism, wherein... The machine tool includes a base and a translation drive. The worktable is movably mounted on the base via a horizontal slide rail and is driven to reciprocate by the translation drive, thereby moving the workpiece clamped on the worktable to the desired position.

[0008] The first and second processing mechanisms are respectively located on both sides of one end of the base, and both the first and second processing mechanisms are five-axis linkage milling mechanisms, both including double swing milling heads, which makes the machine tool highly flexible in milling processing.

[0009] The third machining mechanism is located at the other end of the base and includes an inclined spindle that points towards the worktable, thereby further enriching the machine tool's machining capabilities, machining flexibility, and application range.

[0010] The workpiece on the workbench is processed by at least one of the first, second, and third processing mechanisms.

[0011] The composite milling and turning machine tool provided by this invention adopts a multi-spindle head design, equipped with three spindle heads, namely a slant spindle and two double-swivel milling heads, which supports a variety of machining methods and composite machining requirements. In addition, the two double-swivel milling heads adopt a five-axis linkage mechanism, which can realize two sets of five-axis linkage milling functions, thus expanding the machining capabilities and application range of the machine tool.

[0012] Preferably, to further improve the machining flexibility of the machine tool, the composite milling and turning machine tool further includes a rotary table. The rotary table includes a mounting base, a rotary table body, and a rotation drive component. The mounting base is mounted on the worktable, and the rotary table body and the rotation drive component are mounted on the mounting base. The rotary table body is rotatably mounted and driven to rotate by the rotation drive component, thereby driving the clamped workpiece to rotate and allowing each spindle head to process the workpiece from more angles, thus possessing high flexibility.

[0013] Preferably, the spindle positioning function of the double-swing milling head is combined with the rotation function of the turntable to form a vertical lathe function, which further improves the processing flexibility and efficiency of the machine tool.

[0014] Preferably, to further improve processing flexibility, the two double-swing milling heads are distinguished: the double-swing milling head of the first processing mechanism is a vertical double-swing milling head, and the double-swing milling head of the second processing mechanism is a horizontal double-swing milling head, thereby enabling milling functions at different angles and further improving the processing capability of the machine tool.

[0015] Preferably, the first machining mechanism includes a first crossbeam, a vertical saddle, and a vertical spindle box. The first crossbeam is located at the top of the base. The vertical saddle is slidably mounted on the first crossbeam via a transverse slide rail and is driven to move by a transverse drive member. The vertical spindle box is slidably mounted on the vertical saddle via a vertical track and is driven to move by a vertical drive member. The vertical double-swing milling head is mounted at the bottom end of the vertical spindle box.

[0016] Preferably, the second machining mechanism includes a second crossbeam, a horizontal saddle, and a horizontal spindle box. The second crossbeam is located at the top of the base. The horizontal saddle is slidably mounted on the second crossbeam via a transverse slide rail and is driven to move by a transverse drive member. The horizontal spindle box is slidably mounted on the horizontal saddle via a vertical rail and is driven to move by a vertical drive member. The horizontal double-swing milling head is mounted on the bottom side of the horizontal spindle box.

[0017] Preferably, in order to simplify the structure and form a more stable support effect, the first and second crossbeams are the same crossbeam, and the two ends of the crossbeam are supported by the right column and the left column, respectively.

[0018] Preferably, the third machining mechanism includes a slanted shaft column and a slanted shaft spindle box. The slanted shaft column is mounted on the end of the base and is provided with a downward-sloping guide rail. The slanted shaft spindle box is slidably mounted on the guide rail and is driven to move by a slanted drive component.

[0019] Preferably, the translation drive, lateral drive, vertical drive, and diagonal drive all adopt a lead screw and nut drive structure, which has high movement control accuracy.

[0020] Preferably, there are two horizontal slide rails, arranged in parallel and spaced apart. The base has chip removal grooves on the outer side of each horizontal slide rail to facilitate the collection and cleaning of workpiece machining debris.

[0021] Preferably, the first machining mechanism, the second machining mechanism and the third machining mechanism all further include a tool magazine, which is installed next to the spindle of each machining mechanism.

[0022] As can be seen from the above description of the present invention, the present invention has the following beneficial effects: 1. The composite milling and turning machine tool provided by the present invention adopts a multi-spindle head design and is equipped with three spindle heads, namely a slant spindle and two double swing milling heads, which supports a variety of machining methods and composite machining requirements; 2. The two double-swing milling heads provided by this invention adopt a five-axis linkage mechanism, which can realize two sets of five-axis linkage milling functions, thus expanding the processing capabilities and application range of the machine tool; 3. The composite milling and turning machine tool provided by the present invention can perform multiple processing on the workpiece. The workpiece does not need to be repeatedly transferred and clamped between multiple processing machine tools. Multi-face processing of the workpiece can be completed in one clamping. It is particularly suitable for mass production scenarios, which can improve processing efficiency and accuracy, and also reduce manual intervention and labor costs. 4. The composite milling and turning machine tool provided by this invention is equipped with a rotary table, which can further improve the machining flexibility of the machine tool and allow each spindle head to process the workpiece from more angles; 5. The double-swing milling head has a spindle positioning function. When combined with the rotation function of the turntable, it can form a vertical lathe function, further improving the processing flexibility and efficiency of the machine tool. 6. Of the two double-swing milling heads, one is vertical and the other is horizontal, thus enabling milling functions at different angles and further improving the machine tool's processing capabilities; 7. The first and second processing mechanisms use the same crossbeam, which simplifies the structure and creates a more stable support effect. Attached Figure Description

Detailed Implementation

[0025] To make the technical problems, technical solutions, and beneficial effects of this invention clearer and more understandable, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0026] Please see Figures 1 to 10 To solve the above-mentioned technical problems, the present invention proposes a composite machine tool with strong processing capabilities.

[0027] A special-purpose machine tool with combined turning and milling functions includes a machine base 1, a worktable 2, a first machining mechanism 3, a second machining mechanism 4, and a third machining mechanism 5, wherein... The machine tool 1 includes a base 11 and a translation drive 12. The worktable 2 is movably mounted on the base 11 via a horizontal slide rail 13 and is driven to reciprocate by the translation drive 12, thereby moving the workpiece clamped (the worktable 2 is provided with a clamping slot) on the worktable 2 to the required position.

[0028] Optionally, there are two horizontal slide rails 13, arranged in parallel and spaced apart. The base 11 is provided with chip removal grooves 14 on the outer side of each horizontal slide rail 13 to facilitate the collection and cleaning of machining chips from the workpiece.

[0029] The first processing mechanism 3 and the second processing mechanism 4 are respectively arranged on both sides of one end of the base 11, preferably symmetrically. Both the first processing mechanism 3 and the second processing mechanism 4 are five-axis linkage milling mechanisms, and both include double swing milling heads, which makes the machine tool highly flexible in milling processing.

[0030] The double-swing milling head itself has two mutually perpendicular rotating shafts, which, together with the crossbeam, saddle and spindle box on which it is installed, form a five-axis linkage system. The double-swing milling head (in this embodiment, the double-swing milling head with model CZXT70.5) and the five-axis linkage system are both existing technologies, and will not be described in detail here.

[0031] Preferably, to further improve processing flexibility, the two double-swing milling heads are distinguished: the double-swing milling head of the first processing mechanism 3 is a vertical double-swing milling head 31, and the double-swing milling head of the second processing mechanism 4 is a horizontal double-swing milling head 41, thereby forming milling functions at different angles and further improving the processing capability of the machine tool.

[0032] In one embodiment, the first machining mechanism 3 includes a first crossbeam 32, a vertical saddle 33, and a vertical spindle box 34. The first crossbeam 32 is located at the top of the base 11. The vertical saddle 33 is slidably mounted on the first crossbeam 32 via a transverse slide rail and is driven to move by a first transverse drive member 36. The vertical spindle box 34 is slidably mounted on the vertical saddle 33 via a vertical track and is driven to move by a first vertical drive member 37. The vertical double-swing milling head 31 is mounted at the bottom end of the vertical spindle box 34.

[0033] The second machining mechanism 4 includes a second crossbeam 42, a horizontal saddle 43, and a horizontal spindle box 44. The second crossbeam 42 is located on the top of the base 11. The horizontal saddle 43 is slidably mounted on the second crossbeam 42 via a transverse slide rail and is driven to move by a second transverse drive member 46. The horizontal spindle box 44 is slidably mounted on the horizontal saddle 43 via a vertical rail and is driven to move by a second vertical drive member 47. The horizontal double-swing milling head 41 is mounted on the bottom side of the horizontal spindle box 44.

[0034] Based on the above embodiments, in order to simplify the structure and form a more stable support effect, the first crossbeam 32 and the second crossbeam 42 adopt the same crossbeam, and the two ends of the crossbeam are supported by the right column 35 and the left column 45 respectively.

[0035] The third machining mechanism 5 is located at the other end of the base 11 and includes an inclined spindle 51 that points towards the worktable 2, thereby further enriching the machining capabilities, machining flexibility and application range of the machine tool.

[0036] In one embodiment, the third machining mechanism 5 includes a slanted shaft column 52 and a slanted shaft spindle box 53. The slanted shaft column 52 is mounted on the end of the base 11 and is provided with a downward-sloping guide rail. The slanted shaft spindle box 53 is slidably mounted on the guide rail and is driven to move by a slanted drive member 54.

[0037] The workpiece on the worktable 2 is processed by at least one of the first machining mechanism 3, the second machining mechanism 4, and the third machining mechanism 5. The first machining mechanism 3, the second machining mechanism 4, and the third machining mechanism 5 all include a tool magazine 6, which is installed next to the spindle of each machining mechanism to provide automatic tool changing function for the double-swing milling head and the slant spindle head.

[0038] Based on the above embodiments, to further improve the machining flexibility of the machine tool, in one embodiment the composite milling and turning machine tool further includes a rotary table 7. The rotary table 7 includes a mounting base 71, a rotary table body 72, and a rotation drive 73. The mounting base 71 is mounted on the worktable 2, and the rotary table body 72 and the rotation drive 73 are mounted on the mounting base 71. The rotary table body 72 is rotatably mounted and driven to rotate by the rotation drive 73, thereby driving the clamped workpiece to rotate, allowing each spindle head to process the workpiece from more angles, thus possessing high flexibility.

[0039] Furthermore, the spindle positioning function of the double-swing milling head is combined with the rotation function of the turntable 7 to form a vertical lathe function, which further improves the processing flexibility and efficiency of the machine tool.

[0040] Based on the above embodiments, the translation drive 12, the lateral drive, the vertical drive, and the diagonal drive 54 all adopt a lead screw and nut drive structure, which has high movement control accuracy. It should be noted that the motor lead screw and nut drive structure is existing technology and has the advantage of high precision; its specific structure and working principle will not be described in detail here.
