DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figures 1 to 8 This embodiment provides a composite machining center, including a base 1 and a fixed base 2 arranged on both sides of the base 1, a position regulator 3 is arranged on the top of the fixed base 2, a clamping assembly 4 is arranged at one end of the position regulator 3, and a driving assembly 5 for driving the clamping assembly 4 to rotate and position and clamp is connected to one end of the clamping assembly 4 connected to the position regulator 3, and an annular track 8 is arranged on the front and rear sides of the fixed base 2, and a sliding member 9 is arranged on the annular track 8 to make an arc motion along the annular track 8, and a position regulating assembly 10 is connected to one side of the sliding member 9, and the position regulating assembly 10 is connected to a tool processing assembly 12. The workpiece is positioned and clamped by the clamping assembly 4. After completing the processing of a single surface of the workpiece, the driving assembly 5 drives the clamping assembly 4 and the workpiece to rotate directly to another processing surface, and the tool processing assembly 12 directly processes the processing surface, without stopping the machine to re-clamp and re-position the workpiece, avoiding the generation of deviations during the readjustment process and improving the processing accuracy. Furthermore, by moving the sliding member 9 along the annular track 8, the sliding member 9 drives the position adjustment component 10 and the tool processing component 12 to move to directly above the workpiece at an angle of 45 degrees, 60 degrees, etc., so that the inclined surface of the workpiece can be processed without re-adjusting the position of the workpiece, thereby improving the processing accuracy.

[0032] Specifically, the clamping assembly 4 includes a clamping head 41, one end of which is mounted with a clamp 42, which can clamp the workpiece, and a frame is welded inside the clamp 42, and the workpiece is clamped and fixed with bolts inside the frame, so as to facilitate the processing of the workpiece. The other end of the clamping head 41 passes through the outer wall of the position regulator 3 and extends to the inner cavity to be connected with the driving assembly 5.

[0033] Specifically, the driving assembly 5 includes a roughing driving part 51 and a fine machining driving part 52. The roughing driving part 51 includes a roughing stepping motor 511. The output end of the roughing stepping motor 511 is connected to a first gear 512. The first gear 512 is meshed with a second gear 513. The second gear 513 is arranged at one end of the clamping head 41 away from the clamp 42. The rotational power of the roughing stepping motor 511 is output to the clamping head 41 through a pair of gear sets, namely, the first gear 512 and the second gear 513. The fine machining driving part 52 includes a fine machining stepping motor 521. The fine machining stepping motor 521 is mounted on a movable seat 526. The bottom end of the movable seat 526 is mounted in a movable groove 527. The movable seat 526 can drive the fine machining stepping motor 521 to reciprocate in the movable groove 527. The output end of the finishing stepper motor 521 is connected to a gear column 522, and gear teeth 523 are arranged on the outer side of the gear column 522. The end of the clamping head 41 close to the second gear 513 is provided with a first gear groove 525, and the first gear groove 525 is meshed with the gear teeth 523. The end of the gear column 522 away from the first gear groove 525 is sleeved with a positioning frame 524, and the positioning frame 524 is provided with a second gear groove 528 meshed with the gear teeth 523. The gear column 522 can move along the positioning frame 524. During processing, the gear column 522 is meshed between the positioning frame 524 and the first gear groove 525. During finishing, the gear column 522 is meshed with the clamping head 41, and during rough processing, the gear column 522 is separated from the clamping head 41.

[0034] After finishing the rough machining of one surface of the workpiece, it is necessary to rough machine the other surface. The rough machining stepper motor 511 outputs the rotational power to the main support rod structure of the clamping head 41 through the first gear 512 and the second gear 513, and transmits it to the workpiece through the fixture 42, driving the workpiece to the other surface that needs to be rough machined and then stops rotating and remains in this state. At this time, the tool processing assembly 12 can rough machine the surface. At this time, the finishing stepper motor 521 is pulled toward the end away from the clamping head 41 through the extension rod at the rear end of the gear column 522, and the gear column 522 is disengaged from the first gear tooth groove 525 and meshed in the interior of the positioning frame 524 to achieve the positioning effect, so that the initial position of the finishing stepper motor 521 can be corrected with the initial position of the fixture 42 when docking next time.

[0035] After finishing one surface of the workpiece, it is necessary to finish the other surface. At this time, the roughing stepper motor 511 is powered off. The roughing stepper motor 511 uses inertia to ensure that the equipment is completely still. The clutch of the roughing stepper motor 511 is disconnected, and the first gear 512 and the second gear 513 also gradually stop rotating. At this time, the movable seat 526 drives the finishing stepper motor 521 to move in the movable slot 527 toward the direction close to the clamping head 41. The finishing stepper motor 521 extends through the rear end of the gear column 522. The long rod pushes the gear column 522, and the gear column 522 moves from the inside of the positioning frame 524 to the inside of the first gear groove 525, and the gear teeth 523 enter the first gear groove 525. As the gear column 522 moves, the gear column 522 is completely engaged with the first gear groove 525, and the finishing stepper motor 521 is connected to the fixture 42 and the workpiece. The finishing stepper motor 521 drives the workpiece to rotate to another surface that needs to be finished and then stops rotating, and maintains this state so that the prop processing component 12 can finish the surface.

[0036] Specifically, the gear tooth 523 is shaped as a bullet head structure with a sharp end, which facilitates the entry of the gear tooth 523 on the gear column 522 into the first gear groove 525 and ensures stable meshing between the first gear groove 525 and the gear tooth 523 .

[0037] Specifically, the gear column 522 will be simultaneously engaged between the first gear groove 525 and the positioning frame 524 only when docked. In any working state, the gear column 522 is either completely engaged in the first gear groove 525 or completely engaged in the positioning frame 524.

[0038] Specifically, the positioning frame 524 can achieve stable docking between the first gear groove 525 and the gear teeth 523, thereby avoiding load on the finishing stepping motor 521 during docking, which affects the service life.

[0039] Specifically, after the finishing stepper motor 521 is docked with the fixture 42, it is necessary to cooperate with the mechanical calibration point on the outside of the fixture 42 and the detection structure. The finishing stepper motor 521 drives the fixture 42 to rotate one circle to determine the precise position of the calibration point, and use this position as the initial position to continue subsequent processing. This process generally uses high-precision laser signals for calibration.

[0040] Specifically, the annular track 8 and the sliding member 9 are slidingly assembled, a worm gear 13 is arranged above the sliding member 9, and a worm gear 14 is arranged outside the annular guide rail 8, and the worm gear 14 and the worm gear 13 are meshed with each other. The worm gear 13 rotates under the drive of the motor, thereby driving the sliding member 9 to slide along the outer arc track of the annular track 8 on the outer side of the annular track 8. The sliding member 9 can drive the position adjustment component 10 and the tool processing component 12 to move along the annular guide rail 8 to the top of the workpiece at an angle of 45 degrees, 60 degrees, etc., so that the inclined surface of the workpiece can be processed without re-adjusting the position of the workpiece, thereby improving the processing accuracy.

[0041] Specifically, the displacement adjustment assembly 10 includes a lifting rod 101, which is arranged on the inner side of the sliding member 9, and a first sliding block 17 is arranged on the inner side of the sliding member 9. A sliding groove 15 is arranged inside the lifting rod 101, and a sliding bar 16 is installed inside the sliding groove 15. The sliding bar 16 passes through the first sliding block 17, and the sliding bar 16 can reciprocate up and down along the first sliding block 17. The lifting rod 101 drives the lateral displacement rod 102, the sliding bar 103 and the tool processing assembly 12 to move up and down through the sliding bar 16 and the first sliding block 17. The bottom end of the sliding bar 16 is connected to the outer wall of the lateral displacement rod 102, and a second sliding block 18 is arranged inside the lateral displacement rod 102. The second sliding block 18 is connected to both ends of the sliding bar 103, and the second sliding block 18 drives the sliding bar 103 to move along the axial direction of the lateral displacement rod 102. The sliding bar 103 is provided with a tool processing assembly 12 that moves along the axial direction of the sliding bar 103. The displacement adjustment component 10 can drive the tool processing component 12 to perform three-dimensional displacement, so that the tool processing component 12 can process the workpiece from various angles.

[0042] Specifically, the tool processing assembly 12 includes a displacement member 121, a processor 122 is arranged at the rear side of the displacement member 121, a processing head 123 is arranged at the bottom of the processor 122, a rotating mechanism is arranged at the bottom end of the processing head 123, and a milling cutter head is installed in the rotating mechanism. The displacement member 121 is arranged on the slide bar 103, and the displacement member 121 drives the processor 122 to move along the axial direction of the slide bar 103, so that the milling cutter can flexibly process the workpiece. The processor 122 is a processing tool head device that can be telescopically moved and can automatically switch the processing head 123. It can be understood as a tool magazine structure commonly used in CNC such as a bamboo hat-shaped tool magazine or an umbrella-shaped tool magazine in the prior art equipment. The processor 122 is a processing device that can drive the tool magazine to rise and fall. The processor 122 can drive the processing head 123 to process the workpiece perpendicular to the slide bar 103 along the plane where the axis of the slide bar 103 and the processor 122 intersect.

[0043] Specifically, the inner cavity of the base 1 is provided with a plurality of lifters 6, which penetrate the inner cavity of the base 1 from top to bottom and extend to the outside of the base 1, and the upper end surface of the base 1 is provided with a waste receiving tray 7, the lower end of the waste receiving tray 7 is connected to the lifter 6, and the lifter 6 drives the waste receiving tray 7 to be lifted. When in use, the lifter 6 can be extended and retracted, thereby driving the waste receiving tray 7 to be lifted and lowered, and the waste receiving tray 7 is used to collect waste produced by workpiece processing, and the lifting and lowering coordination is used to reduce the falling distance of the debris, thereby avoiding the splashing of processing debris.

[0044] Specifically, a reinforcing beam 11 is provided inside the sliding member 9.
