[0001] The present invention relates to the technology of rotary tables, and specifically to a rotary table for a numerical control machine tool and its usage method. Background Art

[0002] A numerical control machine tool is an automated machine tool equipped with a program control system. This control system can logically process a program specified by control codes or other symbolic instructions, decode it, represent it in coded numbers, and input it into the numerical control device through an information carrier.

Moreover, traditional rotary tables are mostly fixed devices and do not have the function of adjusting their own level. The unevenness of the worktable during processing will affect the machining accuracy of the bearings. When machining on a rotary table, a large amount of metal chips will be generated, and the metal chips will scatter everywhere, easily causing dirt on the rotary table, and the chips entering the fine gaps of the machine tool components will affect the normal operation of the machine tool components.

By driving the rotation of the exhaust fan inside the processing box with a driving motor, the processing box can suck the chips generated during machining on the rotary table body through the chip suction pipe, without causing adverse effects on the normal operation of the machine tool components, and solve the problems that the rotation mode of the rotary table is single and not convenient for the machine tool to perform multi-directional machining operations, and the chips generated during machining have an adverse effect on the machining operations of the machine tool, and propose a rotary table for a numerical control machine tool and its usage method.

[0013] As a preferred embodiment of the present invention, the lower end of the drive motor is rotatably connected to a defrosting drive runner through a rotating shaft.

[0014] As a preferred embodiment of the present invention, a sorting box is installed on one side of the outer wall of the processing box.

A number of evenly distributed electromagnet bars are connected to the outer wall of the conveyor belt.

A discharge pipe is integrally formed on the lower surface of the sorting box corresponding to the position of the scraping plate. A deburring driving gear is rotatably connected to the rear surface of the sorting box corresponding to the position of the rotating rollers. A deburring driving gear wheel is rotatably connected to the rear surface of the sorting box corresponding to the position of the deburring driving gear through a support frame. The deburring driving gear wheel is drivingly connected to a deburring driving wheel through a transmission belt.

[0015] As a preferred embodiment of the present invention, the method of using the rotary table of a numerically controlled machine tool includes the following steps:

[0016] Step 1: When the driving motor is working, it drives the driving wheel to rotate. The driving wheel, the first adjusting wheel and the first gear wheel are drivingly connected through a transmission belt. The first adjusting slider connected to the first adjusting wheel slides in the inner side of the first adjusting chute under the action of the first adjusting push rod. When the first adjusting wheel slides to one side inside the first adjusting chute, the transmission belt sleeved outside the driving wheel, the first adjusting wheel and the first gear wheel is tightened. After being tightened, the driving wheel can drive the first gear wheel to rotate. The first gear wheel is engaged with the rotating tooth groove on the lower surface of the rotary table body, so that the first gear wheel drives the rotary table body to rotate for angle adjustment, and the workpiece clamped on the rotary table body can rotate on the Z axis.

[0017] Step 2: When the driving motor is working, it drives the driving wheel to rotate. The second rotating gear, the second adjusting wheel and the driving wheel are drivingly connected through a transmission belt. The second adjusting slider connected to the second adjusting wheel slides in the inner side of the second adjusting chute under the action of the second adjusting push rod. After the second adjusting slider slides to one side inside the second adjusting chute, the transmission belt sleeved outside the second rotating gear, the second adjusting wheel and the driving wheel is tightened. After being tightened, the driving wheel can drive the second rotating gear to rotate. The second rotating gear is perpendicular and engaged with the steering gear. The steering gear and the turning driving gear are on the same horizontal plane, so that the second rotating gear can drive the turning driving gear to rotate. The turning driving gear is sleeved outside the turning cross shaft, so that during the rotation of the turning cross shaft, the rotary table body can be driven to turn through the turning ring connected to the outside of the turning cross shaft, and the workpiece clamped on the rotary table body can rotate on the X axis. When adjusting the turning of the rotary table body, the position of the first adjusting slider can be moved through the first adjusting push rod, so that the transmission belt sleeved outside the driving wheel, the first adjusting wheel and the first gear wheel is loosened, so that the rotation angle of the rotary table body on the Z axis will not be affected when adjusting the turning of the rotary table body.

[0018] Step 3: When the telescopic push rod connected to the limiting frame of the turning drive gear and the rotating drive gear adjusts its length, both the turning drive gear and the rotating drive gear slide on the turning cross shaft. The turning drive gear disengages from the turning cross shaft and slides to the sliding groove position. The rotating drive gear displaces at the sliding groove position to complete the docking with the sliding ring. When the steering gear rotates driven by the second rotating gear and drives the rotating drive gear and the turning drive gear to rotate, the turning cross shaft will not rotate. The rotating drive gear can drive the sliding ring to slide and rotate inside the sliding groove. The upper toothed ring connected above the sliding ring is engaged with the rotating transmission gear, enabling the sliding ring to drive the rotating transmission gear to rotate. The rotating shaft is rotationally connected to the rotating transmission gear through a universal joint, so that the rotating linkage gear connected to the rotating shaft drives the ring formed by the connection of the movable rotating ring and the fixed rotating ring to rotate inside the rotating support frame during rotation by engaging with the engaging tooth grooves on the outer sides of the movable rotating ring and the fixed rotating ring. The several clamping push rods connected to the inner sides of the movable rotating ring and the fixed rotating ring can clamp and fix the workpiece placed inside. During the rotation of the ring formed by the connection of the movable rotating ring and the fixed rotating ring inside the inner side of the rotating support frame, the processing angle of the workpiece can also be adjusted;

[0019] Step 4: When the rotary table body performs machine tool processing operations, the impurity removal drive runner connected to the lower end of the drive motor drives the exhaust fan installed inside the processing box to rotate through a transmission belt, so that the exhaust fan transmits the air inside the processing box downward. The debris generated during processing on the rotary table body can be transmitted into the inner side of the processing box through the inner part of the blanking pipe at the nearest position under the action of the wind. The support frame, the exhaust fan, and the impurity removal transmission runner are connected together through a rotating shaft. When the support frame rotates following the impurity removal transmission runner, the semi-convex balls on the outer side of the support frame are pressed against the semi-convex balls on the screen frame, causing the screen frame to shake up and down continuously, enabling the screening operation of the debris and impurity entering the inner side of the processing box. The dust particles in the debris pass through the screen and are discharged downward. The conveyor belt inside the sorting box rotates and conveys under the drive of the rotating roller. During the conveying process, the electromagnets connected to the conveyor belt are controlled by the machine tool control system. The electromagnets on the conveyor belt transmitted to the lower part are energized to work, adsorbing the metal in the debris. The electromagnets on the conveyor belt transmitted to the upper part are de-energized, facilitating the scraping plate to scrape off the debris still attached to the conveyor belt on the conveyor belt, realizing the classified recycling of the debris.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The rotation adjustment of the rotary table body in the Z-axis direction is realized by driving the rotary table body to rotate with a driving motor. The rotation adjustment of the rotary table body in the X-axis direction is realized by driving the turning cross shaft to rotate with a driving motor. The rotation adjustment of the rotary table body in the Y-axis direction is realized by rotating the workpiece with a rotary support frame. The magnitude of the rotation adjustment angle is controlled by the machine tool control system, making it more convenient for the machine tool to process the workpiece.

[0022] 2. By driving the exhaust fan inside the processing box to rotate with a driving motor, the processing box can suck the chips generated during processing on the rotary table body through the chip suction pipe, reducing the amount of chips remaining on the rotary table body, not causing adverse effects on the normal operation of the machine tool components, and making the surface of the rotary table body cleaner.

[0037] In the prior art, the rotation of the rotating workbench is mostly driven by the rotation of a motor, and it can only achieve planar rotation, with single functionality and unable to complete the processing of complex products.

[0043] When the rotary table body 2 is performing machine tool processing operations, the impurity removal driving runner 45 connected to the lower end of the driving motor 313 drives the exhaust fan 46 installed inside the processing box 42 to rotate through the transmission belt 312, so that the exhaust fan 46 transmits the air inside the processing box 42 downward, enabling the debris generated during the processing on the rotary table body 2 to be transmitted into the inner side of the processing box 42 through the blanking pipe 43 at the nearest position under the action of the wind. The support frame 47, the exhaust fan 46 and the impurity removal transmission runner 412 are connected together by a rotating shaft. When the support frame 47 rotates following the impurity removal transmission runner 412, the semi-convex balls 413 on the outer side of the support frame 47 are pressed against the semi-convex balls 413 on the screen frame, causing the screen frame to continuously shake up and down, enabling the screening operation of the debris and impurity entering the inner side of the processing box 42. The dust particles in the debris pass through the screen and are discharged downward. The conveyor belt 411 inside the sorting box 44 rotates and conveys under the drive of the rotating roller 410. During the conveying process, the electromagnet connected to the conveyor belt 411 is controlled by the machine tool control system. The electromagnet on the conveyor belt 411 transmitted to the lower part is powered on to work, adsorbing the metal in the debris, and the electromagnet on the conveyor belt 411 transmitted to the upper part is powered off, facilitating the scraping plate 48 to scrape off the debris still attached to the conveyor belt 411, realizing the classified recovery of the debris.

After being tightened, the driving runner (314) can drive the first gear runner (39) to rotate. The first gear runner (39) is engaged with the rotating tooth groove (37) on the lower surface of the rotary table body (2), so that the first gear runner (39) drives the rotary table body (2) to rotate for angle adjustment, enabling the workpiece clamped on the rotary table body (2) to rotate on the Z axis; Step 2: When the driving motor (313) is working, it drives the driving wheel (314) to rotate. The second gear (316), the second adjusting wheel (323) and the driving wheel (314) are connected to each other through the transmission belt (312).

The turning drive gear (327) disengages from the turning cross shaft (324) and slides to the position of the sliding groove (328). The rotary drive gear (326) displaces at the position of the sliding groove (328) to complete the docking with the sliding ring (330). When the steering gear (325) rotates driven by the second rotating gear (316) and drives the rotary drive gear (326) and the turning drive gear (327) to rotate, the turning cross shaft (324) does not rotate. The rotary drive gear (326) can drive the sliding ring (330) to slide and rotate inside the sliding groove.

The rotary shaft (34) is rotationally connected to the rotary transmission gear (322) through a universal joint (321). When the rotary linkage gear (317) connected to the rotary shaft (34) rotates, it engages with the engaging tooth grooves (35) on the outer sides of the movable rotating ring (33) and the fixed rotating ring (36) to drive the ring formed by the connection of the movable rotating ring (33) and the fixed rotating ring (36) to rotate inside the rotary support frame (32).

The support frame (47), the exhaust fan (46), and the impurity removal transmission runner (412) are connected together by a rotating shaft. When the support frame (47) rotates following the impurity removal transmission runner (412), the semi-convex balls (413) on the outer side of the support frame (47) are squeezed against the semi-convex balls (413) on the screen frame, causing the screen frame to jitter up and down continuously, enabling the screening operation of the debris and impurity entering the inner side of the processing box (42).
