[0028] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present utility model in conjunction with the attached drawings of the specification.

[0029] Embodiment 1

[0030] Refer to Figures 1-5, which is the first embodiment of the present utility model, provides a five-axis linkage turning and milling compound machine tool for rotating and positioning a workpiece in two directions. Such a five-axis linkage turning and milling compound machine tool for rotating and positioning a workpiece in two directions includes a bed 1. A rotating shaft 3 is rotatably provided on one side of the top of the bed 1. A spindle box 4 is fixedly installed at the rotating end of the rotating shaft 3. A driving spindle 5 is provided on the spindle box 4, and a fixture is installed on the driving spindle 5. An inclined panel 6 is fixedly installed on the rear side of the top of the bed 1 and away from the rotating shaft 3. A walking module is installed on the inclined panel 6, and a tool post structure 9 is installed on the walking module;

[0031] The tool post structure 9 includes a tool post plate 91. Four T-shaped chutes 912 are equidistantly opened at the top of the tool post plate 91. A T-shaped slider 94 is slidably installed in the inner cavity of the T-shaped chute 912. A tool holder 93 for fixing a tool is fixedly installed at the top of the T-shaped slider 94.

[0032] Remove the tailstock, install the tool post structure 9 on the Y-axis module 8. Turning tools and boring tools can be directly installed on the tool post plate 91 to perform turning processing on parts. The boring tool on the tool post plate can be moved left and right to install the boring tool according to the length of the part to be processed. Deeper inner holes of parts can be processed within the same machine travel. Since the turning tool can be directly installed on the tool post plate without a series of part assembly and transfer on the turret, the machining rigidity is greatly improved. Moreover, the tool holder 93 is fixed by magnetic adsorption, which is convenient for quickly replacing the tool holder 93.

[0033] A connecting seat 92 is detachably installed at the bottom of the turret plate 91. Installation grooves 921 with the same number as the T-shaped sliding grooves 912 are provided inside the connecting seat 92. Three linear motors 922 are fixedly installed inside the installation grooves 921. An electromagnet 923 is fixedly installed at the movable end of the linear motor 922. Three linear motors 922 are arranged directly below a single T-shaped sliding groove 912. Up to three tool holders 93 can be installed inside a single T-shaped sliding groove 912, which increases the number of tool holders 93 installed on the turret plate 91 at the same time. Meanwhile, due to the magnetic adsorption between the electromagnet 923 and the iron block 941, when the linear motor 922 drives the electromagnet 923 to move, the tool holder 93 will be driven to move, and the distance between two adjacent tool holders 93 can be adjusted, which is suitable for processing workpieces of different sizes, with better flexibility. An iron block 941 is embedded at the bottom of the T-shaped slider 94. The T-shaped slider 94 is pushed into the T-shaped sliding groove 912 to slide, so that the tool holder 93 is limited by the T-shaped sliding groove 912, and the tool holder 93 can only move along the direction of the T-shaped sliding groove 912. At the same time, the electromagnet 923 on a single linear motor 922 is correspondingly turned on. The electromagnet 923 generates magnetic force and magnetically adsorbs with the iron block 941, so as to install the tool holder 93 on the turret plate 91, changing the traditional installation method of the tool holder 93 fixed on the turret plate 91 by bolts. The magnetic adsorption installation method is convenient for quickly installing and disassembling the tool holder 93 and replacing the tool holder 93 required for different tools.

[0034] During the use process, the tool arranging structure 9 is driven by the walking module to move in the X-axis axial direction and the Y-axis axial direction. A hole corresponding to the installation hole 911 is opened on the Y-axis module 8, and the tool arranging structure 9 is installed on the Y-axis module 8 by passing a bolt through the installation hole 911 and into the hole inside the Y-axis module.

[0035] The process of installing the tool holder 93 on the turret plate 91 is as follows:

[0036] The T-shaped slider 94 is pushed into the T-shaped sliding groove 912 to slide, so that the tool holder 93 is limited by the T-shaped sliding groove 912, and the tool holder 93 can only move along the direction of the T-shaped sliding groove 912. At the same time, the electromagnet 923 on a single linear motor 922 is correspondingly turned on. The electromagnet 923 generates magnetic force and magnetically adsorbs with the iron block 941, so as to install the tool holder 93 on the turret plate 91.

[0037] Embodiment 2

[0038] Refer to Figures 1-5 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is:

[0039] A cavity 913 is formed at the top of the turret plate 91 and is located between each T-shaped chute 912 and the mounting groove 921, and the top of the electromagnet 923 is located inside the cavity 913.

[0040] A wire cavity 915 is formed on the turret plate 91 between two adjacent cavities 913, and the wire cavity 915 connects the interiors of the two adjacent cavities 913.

[0041] Threaded holes 914 are formed on both sides of the bottom of the turret plate 91, and fixing holes 924 are formed on both sides of the bottom of the connecting seat 92. Each threaded hole 914 is aligned and communicated with the fixing hole 924. A smooth rod bolt is arranged inside the fixing hole 924, and the threaded end of the smooth rod bolt is threadedly connected with the threaded hole 914. The process of fixing the turret plate 91 and the connecting seat 92 is as follows:

[0042] Place the turret plate 91 on the top of the connecting seat 92, align the threaded holes 914 on the turret plate 91 with the fixing holes 924 on the connecting seat 92, and make the interiors of the corresponding two communicate with each other. Pass the smooth rod bolt through the interior of the fixing hole 924 and thread it into the interior of the threaded hole 914, so as to detachably connect the turret plate 91 and the connecting seat 92, which is convenient for separating the turret plate 91 and the connecting seat 92 in the later stage, and thus convenient for maintaining the linear motor 922 in the later stage.

[0043] A row of mounting holes 911 are formed on both sides of the top of the turret plate 91. The arrangement of the cavity 913 makes the distance between the electromagnet 923 and the iron block 941 closer, ensuring a firm magnetic adsorption between the electromagnet 923 and the iron block 941.

[0044] The traveling module includes an X-axis module 7 installed at the inclined end of the inclined panel 6. The movable end of the X-axis module 7 is fixedly installed with a Y-axis module 8, and the tool arrangement structure 9 is installed at the movable end of the Y-axis module 8. The movable end of the Y-axis module 8 is fixedly installed with a Z-axis module 10, and the movable end of the Z-axis module 10 is fixedly installed with a turret 11.

[0045] A chip collection port 2 is formed at the top of the bed body 1. A chip discharging plate 12 is installed in the inner cavity of the chip collection port 2, and the discharging end of the chip discharging plate 12 is located outside the bed body 1. The top of the chip discharging plate 12 is arranged in an inclined plane, and the side close to the rotating shaft 3 is the high point edge. When the turning chips fall from the chip collection port 2 onto the top of the chip discharging plate 12, they are guided by the inclined plane of the chip discharging plate 12, and the turning chips on its surface slide outward and are discharged.

[0046] During use, place the turret plate 91 on the top of the connecting seat 92, align the threaded holes 914 on the turret plate 91 with the fixing holes 924 on the connecting seat 92, and make the interiors of the corresponding two communicate with each other. Pass the optical rod bolt through the interior of the fixing hole 924 and thread it into the interior of the threaded hole 914, so as to detachably connect the turret plate 91 and the connecting seat 92, which is convenient for separating the turret plate 91 and the connecting seat 92 later, and thus convenient for maintaining the linear motor 922 later.

[0047] The remaining structures are the same as those in Embodiment 1.
