[0002] At present, the inclined CNC turret machine can be used for side processing and end surface processing of bar materials. The existing inclined CNC turret machine has a number of tools on the cutter head, which can be used for processing in different processes. During the processing, the bar material can be driven to rotate by the spindle, so that the tool on the cutter head can process the rotating bar material. The bar material can also be fixed so that the tool at a specific position on the cutter head can rotate to achieve processing of the bar material. For long bar materials, in addition to connecting one end of the spindle to the bar material, the other end of the bar material needs to be supported by the tail top seat so that the bar material can remain stable during rotation or processing. For short bar materials, the tail top seat is not required for auxiliary fixation.

The tail top structure is arranged so as to facilitate the fixation of the tail end of a long bar, thereby ensuring the processing accuracy of the long bar; at the same time, the power head structure is arranged so as to facilitate the processing of the end of the bar, thereby improving the processing efficiency of the workpiece.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the manual installation method using bolts is not only inefficient and time-consuming during replacement, but also the bolts are easily loosened due to repeated disassembly and assembly, resulting in unstable installation.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The present application embodiment discloses a CNC turret machine, referring to Figure 1In this embodiment, the CNC turret machine includes a turret machine body 1, a slide rail seat 2, a mounting platform 3, a moving assembly, a rotating plate 4, a limit mechanism and a driving assembly. Among them, there are two slide rail seats 2, and the two slide rail seats 2 are symmetrically installed on the top of the turret machine body 1; the mounting platform 3 is slidably installed on the top of the two slide rail seats 2 at the same time; the moving assembly is arranged on the outer side of one of the slide rail seats 2, and the moving assembly cooperates with the mounting platform 3 to drive the mounting platform 3 to automatically slide on the top of the two slide rail seats 2, so as to move the mounting platform 3 to a specified position, and then the structure on the mounting platform 3 can also be moved to the specified position at the same time, so as to facilitate the processing of the workpiece.

[0025] At the same time, the turn plate 4 is rotatably installed on the top of the mounting platform 3, and the turn plate 4 is a rectangular structure; the driving component is installed inside the mounting platform 3, and the driving component cooperates with the turn plate 4 to drive the turn plate 4 to rotate; the limiting mechanism is arranged on the top of the turn plate 4 to simultaneously fasten and limit the tail top structure 5 and the power head structure 6 on both sides of the turn plate 4.

[0026] The driving assembly drives the rotating plate 4 to rotate, so that the rotating plate 4 drives the tail top structure 5 and the power head structure 6 to rotate, so that the tail top structure 5 or the power head structure 6 can be rotated to a specified position, so as to achieve the effect of automatically and stably positioning the tail top structure 5 or the power head structure 6, thereby improving the efficiency of automatic replacement of the tail top structure 5 or the power head structure 6 and saving time during replacement.

[0027] At the same time, there is no need to install the tail top structure 5 or the power head structure 6 by means of bolts, thereby avoiding the problem of loose bolts and unstable installation caused by multiple disassembly and assembly of the bolts.

[0028] The structures of the moving components, driving components and limiting mechanisms are described in detail below:

[0029] Specifically, refer to Figure 1 and Figure 2 In this embodiment, the moving assembly includes a screw rod 21, a first sliding sleeve 35, a moving motor 22 and a sliding member. The screw rod 21 is rotatably mounted inside one of the slide rail seats 2; the first sliding sleeve 35 is mounted at the bottom of the mounting platform 3, and the first sliding sleeve 35 is threadedly connected to the screw rod 21; the moving motor 22 is mounted on the outer wall of the slide rail seat 2 with the screw rod 21, and the output end of the moving motor 22 is connected to one end of the screw rod 21. When the moving motor 22 is started, the output end of the moving motor 22 drives the screw rod 21 to rotate, so that the mounting platform 3 moves along the length direction of the screw rod 21.

[0030] At the same time, the sliding member is arranged between the other slide rail seat 2 and the mounting platform 3, and the sliding member includes a sliding rod 23 and a second sliding sleeve 36. The sliding rod 23 is fixedly installed inside the other slide rail seat 2, and the sliding rod 23 is arranged parallel to the screw rod 21; the second sliding sleeve 36 is installed at the bottom of the mounting platform 3, and the second sliding sleeve 36 and the sliding rod 23 are slidably matched with each other. By setting the structure in which the second sliding sleeve 36 cooperates with the sliding rod 23, the mounting platform 3 can be effectively limited and guided, so that the mounting platform 3 is more stable during movement.

[0031] In addition, refer to Figure 2 and Figure 3 In this embodiment, the driving assembly includes a rotating shaft 31, a driving motor 32, a driving gear 33 and a driven gear 34. Among them, a mounting cavity is provided inside the mounting platform 3, one end of the rotating shaft 31 is rotatably mounted on the inner bottom side of the mounting cavity through a bearing, and the other end of the rotating shaft 31 passes through the mounting cavity and is fixedly connected to the bottom of the rotating plate 4; the driving motor 32 is also mounted on the inner bottom side of the mounting cavity, and the output end of the driving motor 32 is vertically arranged upward; the driving gear 33 is connected to the output end of the driving motor 32; the driven gear 34 is mounted on the shaft body of the rotating shaft 31, and the driven gear 34 and the driving gear 33 are meshed with each other.

[0032] When the drive motor 32 is started, the output end of the drive motor 32 drives the active gear 33 to rotate, and the active gear 33 drives the driven gear 34 to rotate, and the driven gear 34 drives the rotating plate 4 on the rotating shaft 31 to rotate, so as to facilitate the rotation of the tail top structure 5 and the power head structure 6 fixed on the rotating plate 4, and then the tail top structure 5 or the power head structure 6 can be rotated to the specified position, so as to facilitate the subsequent processing of the workpiece using the tail top structure 5 or the power head structure 6.

[0033] At the same time, refer to Figure 3 In this embodiment, a plurality of slide bars 47 are installed at the bottom of the rotating plate 4, and a slider 48 is installed at one end of the plurality of slide bars 47 away from the rotating plate 4, and a plurality of slide grooves 37 are opened on the top of the mounting platform 3. The slide grooves 37 cooperate with the slide bars 47 and the slider 48 at the same time, so that the rotating plate 4 drives the slide bars 47 and the slider 48 to effectively slide in the slide grooves 37 during the rotation process, thereby not only having an effective bearing effect on the rotating plate 4, but also having an effective guiding effect on the rotating plate 4.

[0034] Preferably, in this embodiment, pulleys 49 are rollingly mounted on both sides of the sliders 48, and the pulleys 49 abut against the groove walls of the slide grooves 37. The arrangement of the pulleys 49 can reduce the friction between the sliders 48 and the groove walls of the slide grooves 37, thereby making the rotating plate 4 smoother during rotation.

[0035] In addition, refer to Figure 4 In this embodiment, the limiting mechanism includes a limiting frame 41, a limiting plate 7 and a closing component. Among them, there are two limiting frames 41, which are symmetrically installed on both sides of the top of the rotating plate 4, and the middle parts and corresponding sides of the two limiting frames 41 are hollowed out, and the corresponding sides of the two limiting frames 41 are provided with limiting grooves 42; there are two limiting plates 7, which are fixedly installed at the bottom of the tail top structure 5 and the power head structure 6 respectively, and the limiting plates 7 cooperate with the limiting grooves 42, so that the tail top structure 5 or the power head structure 6 slides into the limiting grooves 42 through the limiting plates 7, thereby achieving an effective limiting effect on the tail top structure 5 or the power head structure 6.

[0036] At the same time, the closing assembly is arranged at the top middle of the rotating plate 4, specifically, referring to Figure 4 In this embodiment, the closing assembly includes a bidirectional hydraulic cylinder 43, a push rod 44 and a closing plate 45. The bidirectional hydraulic cylinder 43 is installed at the top middle of the rotating plate 4, and the bidirectional hydraulic cylinder 43 is located between the two limiting frames 41; two push rods 44 are provided, and the two push rods 44 are respectively fixedly connected to the piston rods on both sides of the bidirectional hydraulic cylinder 43; two closing plates 45 are provided, and one side of the two closing plates 45 is respectively fixedly installed on one end of the two push rods 44 away from the bidirectional hydraulic cylinder 43, and the two closing plates 45 are respectively matched with the notches of the two limiting grooves 42, so that the closing plates 45 close the notches of the limiting grooves 42.

[0037] When the bidirectional hydraulic cylinder 43 is started, the piston rods on both sides of the bidirectional hydraulic cylinder 43 simultaneously drive the push rod 44 to move, and the push rod 44 drives the closing plate 45 to close the notch of the limiting groove 42, so that the limiting plate 7 on the tail top structure 5 or the power head structure 6 is more firmly installed in the limiting frame 41, thereby effectively improving the stability of the tail top structure 5 or the power head structure 6.

[0038] At the same time, through the structure in which the two-way hydraulic cylinder 43, the push rod 44 and the closing plate 45 cooperate with each other, it is also convenient to release the restriction of the limit plate 7, so that the tail top structure 5 or the power head structure 6 can be easily removed from the limit frame 41, so as to facilitate the maintenance or repair and replacement of the tail top structure 5 or the power head structure 6.

[0039] Preferably, rubber plates 46 are installed on the sides of the two closing plates 45 facing away from each other. The provision of the rubber plates 46 can not only improve the sealing between the closing plates 45 and the limiting grooves 42, but also prevent the closing plates 45 from directly contacting with the tail top structure 5 or the power head structure 6 and causing scratches on each other, thereby effectively protecting the tail top structure 5 or the power head structure 6.

[0040] The implementation principle of a CNC turret machine in an embodiment of the present application is as follows: when it is necessary to use the tail top structure 5 or the power head structure 6 to process the workpiece, the tail top structure 5 and the power head structure 6 are respectively and firmly limited in the two limit frames 41 of the rotating plate 4 by the limiting mechanism in advance, and then the driving motor 32 is started, and the output end of the driving motor 32 drives the active gear 33 to rotate, and the active gear 33 drives the rotating shaft 31 on the driven gear 34 to rotate, and the rotating shaft 31 drives the tail top structure 5 and the power head structure 6 fixedly limited on the rotating plate 4 to rotate, so as to facilitate the required tail top structure 5 or power head structure 6 to be rotated to the specified position.

[0041] Then start the moving motor 22, and the output end of the moving motor 22 drives the screw rod 21 to rotate, so that the mounting platform 3 moves along the screw rod 21 and the sliding rod 23, so as to move the required tail top structure 5 or power head structure 6 on the mounting platform 3 to the specified position, thereby facilitating the subsequent processing of the workpiece, and then completing the process of automatically replacing the tail top structure 5 or the power head structure 6.
