Description

Technical Field

[0001] The invention relates to the technical field of horizontal turntables, in particular to a CNC horizontal turntable device. Background Art

[0002] A horizontal rotary table is a device used to rotate the workpiece in a horizontal machining center. It allows the workpiece to rotate along a horizontal axis to achieve processing at different angles. The horizontal rotary table allows the workpiece to rotate during processing, so that multiple angles can be processed without re-clamping. This greatly reduces the clamping time and the cost of changing fixtures, and improves processing efficiency.

[0003] After searching, the patent with application number CN202122707767.6 discloses a horizontal turntable, including: a base, a brake part is provided on the inner side of the base; a driving motor; a reducer, which includes a reduction input end and a reduction output end, and the reduction input end is connected to the driving motor in a transmission manner; a mounting platform, which is rotatably connected to the base, and the mounting platform is fixedly connected to the reduction output end; a first brake pad, which is fixedly connected to the mounting platform, and the first brake pad is directly opposite to the brake part; a hydraulic drive device, which includes a cylinder body and a piston, and the piston can press the first brake pad and the brake part to realize the braking of the mounting platform. A driving motor and a reducer are arranged in the base to drive the mounting platform to rotate. The structure using the driving motor and the reducer is simpler than the hydraulic drive structure; when the mounting platform needs to brake, the piston of the hydraulic drive device can press the first brake pad and the brake part to brake the mounting platform. The structure using the hydraulic drive brake is more reliable than the motor brake structure, thereby simplifying the drive structure and improving the braking reliability.

[0004] The current horizontal turntable has a poor clamping effect on the workpiece. The moment the clamping structure contacts the workpiece, it is a rigid contact, lacking buffer space and buffer space. Rigid clamping can easily cause irreversible damage to the workpiece and the clamping mechanism, and the height of the workpiece clamped by the clamping structure is not adjustable. When the clamping structure is in a low position, it can better clamp low workpieces, but when the workpiece is high, the clamping position is below the center of gravity of the workpiece, which can easily cause instability of the workpiece when processing the workpiece. Therefore, we need to propose a CNC horizontal turntable device. Summary of the invention

[0005] The purpose of the present invention is to provide a CNC horizontal turntable device. Through the design of the locking component, the clamping mechanism can achieve height adjustment through the height adjustment mechanism, which is convenient for efficiently clamping workpieces of different heights. By adjusting the height of the clamping mechanism, the height of the center of gravity of the workpiece can be clamped to ensure the stability of the workpiece during processing, which is beneficial to improving the processing accuracy of the workpiece. After the interference blocks at the ends of the two rotating plates in the clamping mechanism contact the workpiece, the angle changes under the action of the extrusion force. In the process from contacting the workpiece to clamping the workpiece, there is a certain buffer time and buffer space, which avoids damage to the workpiece and the clamping mechanism caused by rigid clamping, so as to solve the problems raised in the above-mentioned background technology.

[0057] A locking component 400 is installed on the support component 300 and is used to clamp the workpiece to be processed. The locking components 400 are arranged in a ring shape and are equidistantly arranged in multiple groups. The locking components 400 are slidably installed on the surface of the support component 300. The multiple groups of locking components 400 move synchronously and converge toward the center of the workpiece placement table 31 or diverge in a direction away from the center of the workpiece placement table 31 at the same time, so that the workpiece can be positioned at the center of the workpiece placement table 31 as much as possible.

[0058] The locking component 400 includes a height adjustment mechanism 45 slidably mounted on the surface of the supporting component 300 . A liftable clamping mechanism 46 is mounted on the height adjustment mechanism 45 . The height adjustment mechanism 45 is used to adjust the height of the clamping mechanism 46 .

[0059] The locking component 400 also includes a second motor 41 that drives the height adjustment mechanism 45 to move on the surface of the workpiece placement table 31. One end of the output shaft of the second motor 41 is connected to a screw rod 42, and the screw rod 42 is rotatably arranged inside the cavity. A sliding block 43 is threadedly connected to the outer wall of the screw rod 42, and a connecting column 44 is fixed on the top of the sliding block 43. The connecting column 44 is slidably installed inside the strip limiting hole 35.

[0060] When the locking component 400 is driven to operate and clamp the workpiece, the second motor 41 drives the screw rod 42 to rotate. The screw rod 42 cooperates with the thread of the sliding block 43 and, under the limit of the connecting column 44, can drive the sliding block 43 to move along the screw rod 42, thereby driving the height adjustment mechanism 45 and the clamping mechanism 46 to approach or move away from the workpiece.

[0061] The height adjustment mechanism 45 includes a base 451 installed on the top of the connecting column 44, the width of the base 451 is greater than the width of the strip limiting hole 35, and the bottom of the base 451 moves in contact with the surface of the workpiece placement table 31 to increase the stability of the movement of the base 451, and a fixing column 452 is installed on the base 451, and the fixing column 452 is vertically arranged to the base 451. A plurality of threaded blind holes 453 are evenly spaced on the outer wall of the fixing column 452, and a cover plate is arranged on the top of the fixing column 452 to prevent the clamping mechanism 46 from detaching.

[0062] The clamping mechanism 46 includes a fixing plate 461 which can be raised and lowered on the outer wall of the fixing column 452. A through hole 462 is provided on the top of the fixing plate 461. The fixing column 452 is inserted into the through hole 462. The inner diameter of the through hole 462 is equal to the diameter of the fixing column 452. A through hole 463 communicating with the through hole 462 is provided at one end of the fixing plate 461. A fastening screw 464 is installed inside the through hole 463. One end of the fastening screw 464 is threadedly connected to the inside of the threaded blind hole 453.

[0063] By adjusting the height of the clamping mechanism 46, it is convenient to position workpieces of different heights, thereby increasing the applicable scope of the turntable.

[0064] A column 465 is installed at the other end of the fixed plate 461, and the outer wall of the column 465 is rotatably installed with a first rotating plate 466 and a second rotating plate 467, and a limit component 469 for limiting the opening and closing angle is connected between the opposite sides of the first rotating plate 466 and the second rotating plate 467. The ends of the first rotating plate 466 and the second rotating plate 467 are both installed with a resistance block 468 for resisting the workpiece, and the outer wall of the resistance block 468 is provided with a rubber anti-slip pad, which can not only increase the friction with the surface of the workpiece, but also reduce the clamping damage to the workpiece.

[0065] The limiting assembly 469 includes an arc-shaped sleeve installed on the first rotating plate 466 and an arc-shaped insert rod installed on the second rotating plate 467. The arc-shaped insert rod is inserted into the interior of the arc-shaped sleeve. In order to realize automatic resetting of the first rotating plate 466 and the second rotating plate 467 after the workpiece is clamped, a spring is connected between the end of the arc-shaped insert rod and the inner wall of the arc-shaped sleeve. When the abutment block 468 abuts against the workpiece, the angle between the first rotating plate 466 and the second rotating plate 467 becomes larger, and the spring is stretched. After the clamping of the workpiece is cancelled, the first rotating plate 466 and the second rotating plate 467 are pulled to rotate and approach each other by the elastic force of the spring.

[0066] When in use, after placing the workpiece on the workpiece placing table 31, the workpiece is clamped by the locking component 400, and the second motor 41 is operated. The second motor 41 drives the screw rod 42 to rotate, and the screw rod 42 drives the sliding block 43 to move linearly, and drives the connecting column 44 to move inside the strip-shaped limiting hole 35. The connecting column 44 drives the height adjustment mechanism 45 and the clamping mechanism 46 to move, so that the four groups of clamping mechanisms 46 approach each other and gradually fit the workpiece. The interference block 468 in the clamping mechanism 46 first contacts the workpiece. As the interference block 468 continuously squeezes the workpiece, the first rotating plate 466 and the second rotating plate 467 rotate (the angle between the two rotating plates becomes larger), and the arc-shaped insertion rod in the limiting assembly 469 moves inside the arc sleeve, and the spring is stretched until the arc-shaped insertion rod is in place inside the arc sleeve, and the angle between the first rotating plate 466 and the second rotating plate 467 no longer increases, thereby achieving the tightening of the workpiece.

[0067] When processing a workpiece, in order to ensure multi-directional processing of the workpiece, the workpiece placement table 31 in the support component 300 can be driven to rotate by running the driving component 200. Specifically, the first motor 21 drives the first gear 23 to rotate. Since the first gear 23 is meshed with the second gear 24, the second gear 24 drives the worm 25 to rotate, the worm 25 drives the worm wheel 26 to rotate, and the worm wheel 26 drives the transmission component 600 to rotate. Then the transmission shaft 63 in the transmission component 600 drives the workpiece placement table 31 to rotate, thereby realizing the rotation of the workpiece.

[0068] Example 2

[0069] The same as Example 1 will not be repeated here, except that

[0070] See also Figure 8 One end of the fixed plate 461 is connected to a U-shaped block 47, and a universal ball 48 is installed at the end of the U-shaped block 47. A plurality of universal balls 48 are arranged vertically equidistantly, and a pressure plate 49 is installed on the universal ball 48 to abut against the surface of the workpiece, and a layer of rubber anti-slip pad is installed on the surface of the pressure plate 49.

[0071] The pressing plate 49 in this embodiment can rotate within a certain range of angles, that is, the pressing plate 49 can be tilted, which is suitable for firmly clamping workpieces with uneven surfaces and improves the clamping effect on workpieces of various shapes.
