[0021] The invention provides a turning and polishing integrated composite machine tool.

[0022] First embodiment: See also Figures 1 to 8 and Fig.10 A turning and polishing integrated composite machine tool comprises a machine body 1, a turning assembly 4, a machine case 5 and a polishing assembly 9, wherein a switching assembly 2 is arranged inside the machine body 1, wherein the switching assembly 2 comprises two first screw rods 21, both ends of the two first screw rods 21 are rotatably connected to the inner wall of the machine body 1 through bearings, one end of the two first screw rods 21 penetrates the machine body 1 and extends to the outside of the machine body 1, and are respectively connected to pulleys 22 with keyways, and there are two pulleys 22, and the outer wall synchronous sleeves of the two pulleys 22 are provided with synchronous belts 23, and one end of the two pulleys 22 away from the first screw rod 21 is keyway connected to a first motor 24; A housing 3 is fixedly mounted on the outer wall of one end of the body 1, and the first motor 24 is fixedly mounted on the outer wall of the housing 3; A turning assembly 4, the turning assembly 4 comprising a first movable seat 41, the first movable seat 41 being located on the upper surface of the machine body 1, and the bottom of the first movable seat 41 being threadedly connected to the outer wall of one of the two first screw rods 21, a tool holder 42 being fixedly mounted on the upper surface of the first movable seat 41, a turning tool 43 being equidistantly mounted on the upper surface of the tool holder 42, a mounting frame 44 being fixedly connected to the outer wall of one side of the tool holder 42, a support rod 45 being fixedly mounted on the outside of the mounting frame 44, and a guide rod 46 being inserted and connected at the front end axis of the support rod 45 through a latch; The chassis 5 is fixedly mounted on the upper surface of one end of the body 1, and a slide groove 7 is provided on one side of the chassis 5; A cleaning assembly 6, the cleaning assembly 6 comprising a fan 61, the fan 61 being fixedly mounted on the outer wall of the other end of the housing 1, the top of the fan 61 being snap-connected with a hose 62, and the number of the hoses 62 is three, one end of each of the three hoses 62 being sealed and connected with a nozzle 63 through a sealing ring, an outer plate 64 being fixedly mounted on the outside of the nozzle 63, a movable rod 65 being fixedly mounted on the outer wall of one end of the outer plate 64, and the bottom end of the movable rod 65 being interlaced and connected with the outer wall of the chassis 5 through a latch, a connecting rod 66 being fixedly mounted on the outer wall of the bottom end of the movable rod 65, and a counterweight 67 being fixedly mounted on the outer wall of the connecting rod 66; The polishing assembly 9 comprises a second movable seat 91, a mounting plate 92 is fixedly mounted on the upper surface of the second movable seat 91, a gear 93 is rotatably connected to the upper surface of the mounting plate 92 via a bearing, a sliding key is connected to a swivel seat 94 on the upper surface of the gear 93, a protective cover 95 is arranged on the side wall of the swivel seat 94, and a sanding belt 96 is installed inside the protective cover 95.

[0023] In this embodiment, the outer walls of the two first screw rods 21 are provided with screw threads facing each other, so that when the two first screw rods 21 rotate in the same direction, the first movable seat 41 and the second movable seat 91 move relatively on the outer walls of the two first screw rods 21. When the two first screw rods 21 rotate synchronously in the opposite direction, the first movable seat 41 and the second movable seat 91 are reset and relatively moved, so that the first movable seat 41 and the second movable seat 91 can be alternately sent to the processing position of the workpiece; By starting the first motor 24 to rotate the output shaft to drive one pulley 22 to rotate and drive the synchronous belt 23, so that the synchronous belt 23 drives the other pulley 22 to rotate synchronously, so that the two pulleys 22 synchronously drive the two first screw rods 21 to rotate synchronously, so that the two first screw rods 21 can drive the first movable seat 41 and the second movable seat 91 to slide on the upper surface of the machine body 1, so that the compound machine tool can switch the processing mode when processing the workpiece, avoid replacing the processing equipment, and improve the workpiece processing efficiency; Furthermore, when the first movable seat 41 approaches the chassis 5, the side wall of the tool holder 42 drives the mounting frame 44 and the support rod 45 to move, so that the front side of the support rod 45 contacts the bottom of the connecting rod 66, and the bottom of the connecting rod 66 is driven by gravity to drive the movable rod 65 to rotate the outer plate 64. Therefore, the fan 61 is turned on to blow air from the blowing nozzle 63 through the three hoses 62 to clean the waste chips on the surface of the workpiece. Therefore, when the turning tool 43 is processing the workpiece or reciprocating back and forth, the blowing nozzle 63 sweeps and blows the surface of the workpiece to prevent the waste chips from sticking to the surface of the workpiece and causing the turning tool 43 to contact with the waste chips, thereby effectively improving the processing accuracy of the composite machine tool; Please combine Figure 7 When the first movable seat 41 moves to the left, it drives the tool holder 42 and the turning tool 43 to move synchronously. At this time, the support rod 45 on the outer wall of the first movable seat 41 moves to the left synchronously, so that the guide rod 46 at one end of the support rod 45 contacts the bottom side wall of the connecting rod 66. The bottom side wall of the connecting rod 66 is stressed so that the connecting rod 66 is tilted and drives the movable rod 65 to rotate clockwise, so that the top end of the movable rod 65 drives the outer plate 64 and the blowing nozzle 63 to a horizontal state; Please combine Figure 8When the first movable seat 41 moves to the right and drives the tool holder 42 and the turning tool 43 away from the workpiece, the guide rod 46 at one end of the support rod 45 moves away from the connecting rod 66, so that the bottom side wall of the connecting rod 66 loses force and returns to the initial position. At this time, the top end of the connecting rod 66 drives the movable rod 65 to rotate counterclockwise to flip the outer plate 64, so that the blowing nozzle 63 is lifted.

[0024] Second embodiment: See also Figure 1 , Figure 4 , Fig. 9 and Fig.10 A positioning assembly 8 is provided inside the chassis 5, and the positioning assembly 8 includes a second screw rod 81 rotatably connected to the inner wall of the chassis 5 through a bearing, one end of the second screw rod 81 passes through the key slot of the chassis 5 and is connected to a second motor 82, and the second motor 82 is fixedly installed on the outer wall of the chassis 5.

[0025] The outer wall of the second screw rod 81 is threadedly connected to a mounting seat 83, the inner wall of the mounting seat 83 is slidably mounted with a guide rail 84, and the guide rail 84 is fixedly mounted to the inner wall of the chassis 5, and a clamp 85 is installed inside the mounting seat 83, and the clamp 85 passes through the chassis 5 through the slide groove 7.

[0026] A rack 10 is fixedly connected to one side of the mounting plate 92 and located on the upper surface of the machine body 1, and the outer wall of the rack 10 is meshedly connected with the outer wall of the gear 93; In this embodiment, the workpiece is placed in the fixture 85 for clamping, and the second motor 82 is started to drive the second screw 81 to rotate, so that the mounting seat 83 moves on the outer wall of the second screw 81 and slides smoothly through the guide rail 84. The fixture 85 can rotate the workpiece through the servo drive. When turning, the turning assembly 4 and the fixture 85 are close to the workpiece to perform cutting. Therefore, such a design enables the compound machine tool to drive the workpiece to switch between workstations, and can switch to a turning station or a polishing station according to different processing methods; When the workpiece needs to be polished, the first movable seat 41 can be moved away from the workpiece by rotating the first screw rod 21 in the reverse direction through the switching assembly 2, and the second movable seat 91 can be moved closer to the workpiece. At this time, the gear 93 on the upper surface of the mounting plate 92 is meshed with the rack 10, so that the gear 93 can drive the rotating seat 94 to rotate 180°, so that the rotating seat 94 can rotate the shield 95 and the sanding belt 96 to the top of the workpiece, and the surface of the workpiece can be polished and ground by the servo-driven sanding belt 96 transmission; It can be understood that when the compound machine tool uses the turning assembly 4 to process the workpiece, the polishing assembly 9 is away from the workpiece, so that the gear 93 is meshed with the rack 10 again, and the swivel seat 94 is rotated 180° to reset, so that the swivel seat 94 drives the shield 95 and the abrasive belt 96 to rotate to the rear end of the machine body 1, so that it is convenient for the staff to replace the abrasive belt 96 with different meshes; It should be noted that when the workpiece is being polished, the abrasive belts 96 need to be replaced in sequence for polishing, and rough processing and fine processing can be performed on the workpiece to achieve polishing effects for different workpieces.

[0027] Third embodiment: See also Figure 1 , Figure 3 , Figure 4 , Figures 11 to 15 A limiting assembly 11 is provided on the opposite side of the turning assembly 4 and the polishing assembly 9. The limiting assembly 11 includes a resistance rod 111 and a spring rod 112. The resistance rod 111 is fixedly installed on the side wall of the tool holder 42, and the front end of the resistance rod 111 is conical in design.

[0028] The spring rod 112 is arranged on the inner wall of one side of the mounting plate 92, and one end of the spring rod 112 is fixedly connected with a contact block 113 located outside the second movable seat 91, and the outer wall of the contact block 113 is inclined, and the top side wall of the contact block 113 is fixedly connected with a clamping block 114, and the clamping block 114 is located on one side of the gear 93.

[0029] A collecting assembly 12 is provided inside the body 1 and below the chassis 5. The collecting assembly 12 includes a cylinder 121. The cylinder 121 is fixedly installed inside the body 1. A bevel block 122 is fixedly installed on the top of the cylinder 121, and the bevel block 122 is slidably connected to the inner wall of the body 1.

[0030] The top of the chamfered block 122 is attached with a resistance block 123, and the resistance block 123 is located inside the chassis 5. One end of the resistance block 123 away from the chamfered block 122 is fixedly connected with a collection box 124, and the collection box 124 is slidably connected to the inner wall of the chassis 5. In this embodiment, when the polishing assembly 9 approaches the workpiece for processing, the first movable seat 41 and the second movable seat 91 are in the process of switching positions alternately, and the abutment rod 111 on the side wall of the tool holder 42 contacts the outer wall of the contact block 113, so that the outer wall of the abutment rod 111 squeezes the contact block 113 from narrow to wide, so that the contact block 113 pushes the spring rod 112 to be retracted into the inside of the mounting plate 92, and at the same time, the contact block 113 pushes the clamping block 114 to the tooth groove of the gear 93 to limit the gear 93, thereby making the compound machine tool more stable during the polishing process; It should be noted that the spring rod 112 forms an elastic reset motion with the mounting plate 92 through the spring. When the abutment rod 111 moves away from the contact block 113, the contact block 113 loses resistance. At this time, the spring rod 112 can drive the contact block 113 to drive the clamping block 114 to reset away from the gear 93, thereby releasing the restriction on the gear 93. Please combine Fig.12 and Fig.13 When the tool holder 42 moves to the right, the abutment rod 111 is driven to move to the right synchronously. At this time, the mounting plate 92 moves to the left, so that the outer wall of the abutment rod 111 contacts the outer wall of the contact block 113. At this time, the turning process switches to the polishing process state; Please combine Fig.14 and Fig.15 When the knife seat 42 continues to move to the right and the mounting plate 92 continues to move to the left, the contact block 113 contacts the tail end of the abutment rod 111, and the contact block 113 sends the clamping block 114 into the tooth groove of the gear 93. At this time, the polishing state is switched successfully and the polishing process can be performed; Furthermore, when the compound machine tool is performing polishing processing, the cylinder 121 is started to drive the piston rod to push up the bevel block 122, so that the top end of the bevel block 122 squeezes the resistance block 123, so that the resistance block 123 slides sideways and drives the collection box 124 to move out of the chassis 5 to the bottom of the workpiece. Therefore, the compound machine tool can collect the dust and waste powder generated by grinding the workpiece during polishing processing to prevent the powder from being too fine and falling into various corners of the machine tool and being inhaled into the body of the staff.

[0031] Please refer to Figures 1 to 15 The working principle of the turning and polishing composite machine tool provided by the present invention is as follows: Step S1, firstly, put the protective gear into the fixture 85 and fix it, and start the second motor 82 to drive the second screw rod 81 to rotate, so that the mounting seat 83 moves on the outer wall of the second screw rod 81, so that the mounting seat 83 drives the fixture 85 to slide on the inner wall of the slide groove 7 to adjust the position of the workpiece; Step S2, when turning processing is required for the workpiece, the first motor 24 is started to rotate the output shaft to drive one pulley 22 to rotate and drive the synchronous belt 23, so that the synchronous belt 23 drives another pulley 22 to rotate synchronously, so that the two pulleys 22 synchronously drive the two first screw rods 21 to rotate synchronously, so that the two first screw rods 21 can drive the first movable seat 41 and the second movable seat 91 to slide on the upper surface of the machine body 1; Step S3, the fixture 85 is then driven by a servo drive to rapidly rotate the workpiece so as to contact the turning tool 43 for turning processing; Step S4, when the first movable seat 41 approaches the chassis 5, the side wall of the tool holder 42 drives the mounting frame 44 and the support rod 45 to move, so that the front side of the support rod 45 contacts the bottom of the connecting rod 66, and the bottom of the connecting rod 66 is driven by gravity to drive the movable rod 65 to rotate the outer plate 64, so that the fan 61 is turned on to blow air from the blowing nozzle 63 through the three hoses 62 to clean the waste chips on the surface of the workpiece, so that when the turning tool 43 is processing the workpiece or reciprocating back and forth, the blowing nozzle 63 sweeps and blows the surface of the workpiece; Step S5, when the workpiece needs to be polished, the first movable seat 41 can be moved away from the workpiece by rotating the first screw rod 21 in the reverse direction through the switching assembly 2, and the second movable seat 91 can be moved closer to the workpiece. At this time, the gear 93 on the upper surface of the mounting plate 92 is meshed with the rack 10, so the gear 93 can drive the rotating seat 94 to rotate 180°, so that the rotating seat 94 can rotate the shield 95 and the sanding belt 96 to the top of the workpiece, and the sanding belt 96 can contact the surface of the workpiece, and then the sanding belt 96 can be driven by the servo to polish the surface of the workpiece; Step S6, when the composite machine tool is performing polishing, the cylinder 121 is started to drive the piston rod to push up the bevel block 122, so that the top of the bevel block 122 squeezes the abutment block 123, so that the abutment block 123 slides sideways and drives the collection box 124 to move out of the chassis 5 to below the workpiece; Step S7, when the compound machine tool uses the turning assembly 4 to process the workpiece, the polishing assembly 9 is away from the workpiece, so that the gear 93 is meshed with the rack 10 again, and the swivel seat 94 is rotated 180° to reset, so that the swivel seat 94 drives the shield 95 and the abrasive belt 96 to rotate to the rear end of the machine body 1; Step S8, and in the process of alternating positions of the first movable seat 41 and the second movable seat 91, the resistance rod 111 on the side wall of the knife seat 42 contacts the outer wall of the contact block 113, so that the outer wall of the resistance rod 111 squeezes the contact block 113 from narrow to wide, so that the contact block 113 pushes the spring rod 112 to be retracted into the interior of the mounting plate 92, and at the same time, the contact block 113 pushes the clamping block 114 to the tooth groove of the gear 93 to limit the gear 93, and when the resistance rod 111 is away from the contact block 113, the contact block 113 lacks resistance. At this time, the spring rod 112 can drive the contact block 113 to drive the clamping block 114 to reset away from the gear 93, so that the gear 93 can be released from the restriction.
