It can move the machine tool and process parts according to a pre-programmed program. It is a flexible and efficient automated machine tool with strong adaptability to the workpiece, high processing accuracy, stable processing quality and high productivity. A rotary table refers to a machine tool accessory with a rotatable table surface used to clamp workpieces and realize rotation and indexing positioning.

[0003] A prior art patent application for a high-precision rotary table for CNC machine tools describes a rotary table with an adjustment mechanism at the bottom of the main body and a chip cleaning assembly inside the outer frame. The adjustment mechanism includes a limiting strip fixedly connected to the bottom of the main body, a movable table movably connected to the outer side of the limiting strip, a hydraulic rod inside the movable table, and an outer frame slidably connected to the front and rear end faces of the movable table. A slide block is located on the top of the outer frame, and two motors are fixedly connected to the inner wall of the front of the outer frame. Threaded rods are fixedly connected to the output ends of the motors, and threaded holes are provided inside the movable table. This high-precision rotary table for CNC machine tools, through its adjustment mechanism, allows for free adjustment of the rotary table position, reducing the impact of multiple clamping operations on machining accuracy and improving production efficiency and quality.

[0004] However, when using this device, after moving the rotary table to the appropriate position, there is no structure to limit the rotation of the rotary table, which can easily cause the workpiece to shake during processing, thus reducing stability.

[0005] Therefore, it is necessary to provide a precision CNC machine tool rotary table to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] First Embodiment

[0028] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1A schematic diagram of the structure of a first embodiment of a precision CNC machine tool rotary table provided by this utility model; Figure 2 for Figure 1 The diagram shows a cross-sectional view of the mounting base. Figure 3 for Figure 1 The diagram shows a cross-sectional view of the top of the mounting base. Figure 4 for Figure 1 The enlarged schematic diagram of part A is shown. A precision CNC machine tool rotary table includes: a housing 1, a drive motor 2 fixedly mounted at one end of the housing 1, and a lead screw 21 fixedly mounted at the output end of the drive motor 2;

[0029] Sliding seat 3, which is threaded to the outer side of the lead screw 21;

[0030] Mounting base 4 is fixedly mounted on the top of sliding base 3. A pneumatic telescopic rod 41 is fixedly mounted on the bottom of the inner side of mounting base 4. A rotary table 42 is fixedly mounted on the top of pneumatic telescopic rod 41. Limiting rods 43 are fixedly mounted on both ends of the bottom of rotary table 42. The limiting rods 43 are slidably connected to the top of mounting base 4. Side plates 44 are fixedly mounted on both sides of the inner side of mounting base 4. One side of the side plate 44 is attached to the side of the limiting rod 43.

[0031] Two fixed seats 5 are respectively disposed on the front and back of the pneumatic telescopic rod 41. A double-headed pneumatic telescopic rod 51 is fixedly installed inside one of the fixed seats 5. A push plate 52 is fixedly installed at both ends of the double-headed pneumatic telescopic rod 51. A first rubber pad 53 is fixedly installed on one side of the push plate 52. A moving rod 54 is fixedly installed at both ends of one side of the push plate 52. The moving rod 54 is slidably connected to the inside of the side of the mounting seat 4. A limit plate 55 is fixedly installed at one end of the moving rod 54. A second rubber pad 56 is fixedly installed on the side of the limit plate 55.

[0032] The side of the first rubber pad 53 abuts against the side of the limiting rod 43, and the side of the second rubber pad 56 abuts against the inner side of the outer shell 1. This increases the limiting effect, and since both sides of the limiting rod 43 are flat, the contact area with the side plate 44 and the first rubber pad 56 is increased.

[0033] A through-hole 11 is provided at the bottom of the inner side of the outer casing 1, and a feeding groove 12 is provided at the bottom of the through-hole 11.

[0034] The opening 11 allows the slag generated during processing to fall onto the inner side of the feeding trough 12 for subsequent processing by the user.

[0035] The sliding seat 3 has grooves 31 on both sides, and the inner sides of the two grooves 31 are slidably connected to limit strips 13. The two limit strips 13 are respectively fixedly installed on both sides of the inner side of the outer shell 1.

[0036] The sliding seat 3 can slide on the inner side of the limiting strip 13 via the slide groove 31, which increases the stability of the sliding seat 3 when it moves.

[0037] Another mounting base 4 has a double-headed telescopic rod 57 fixedly installed inside, and push plates 52 are fixedly installed at both ends of the double-headed telescopic rod 57.

[0038] The double-headed telescopic rod 57 increases the stability of the push plate 52 when it moves.

[0039] Both sides of the sliding seat 3 are slidably connected to sliding rods 22, and the two ends of the two sliding rods 22 are respectively fixedly installed on the two ends of the inner side of the outer shell 1.

[0040] The working principle of the precision CNC machine tool rotary table provided by this utility model is as follows:

[0041] When in use, the drive motor 2 rotates, which drives the lead screw 21 to be threaded inside the sliding seat 3, thereby enabling the rotary table 42 to move left and right. After moving to the appropriate position, the user can start the pneumatic telescopic rod 41 to adjust the height of the rotary table 42.

[0042] After adjusting the rotary table 42 to a suitable position, the user can activate the double-headed pneumatic telescopic rod 51 to extend it, thereby pushing the push plate 52. Then, one side of the first rubber pad 53 abuts against the side of the limiting rod 43, thus clamping and limiting the limiting rod 43 through the first rubber pad 53 and the side plate 44. At the same time, when the push plate 52 moves, it can also push the moving rod 54, which then drives the limiting plate 55 and the second rubber pad 56 to move, so that the second rubber pad 56 abuts against the inner side of the outer shell 1. In this way, the height and left and right translation positions of the rotary table 42 can be limited, increasing the stability of the rotary table 42 during use.

[0043] Compared with related technologies, the precision CNC machine tool rotary table provided by this utility model has the following beneficial effects:

[0044] The mounting base 4, pneumatic telescopic rod 41, rotary table 42, limiting rod 43, side plate 44, fixed base 5, double-headed pneumatic telescopic rod 51, push plate 52, first rubber pad 53, moving rod 54, limiting plate 55 and second rubber pad 56 work together to limit the position of the rotary table 42. After the rotary table 42 is moved to a suitable position, the push plate 52 can push the second rubber pad 56, thereby limiting the limiting rod 43. The moving rod 54 drives the limiting plate 55 and the second rubber pad 56 to move towards the inner side of the outer shell 1, thereby limiting the position of the mounting base 4. In this way, the height and left and right translation positions of the rotary table 42 can be limited, increasing the stability when processing the workpiece placed on the rotary table 42.

[0045] Second Embodiment

[0046] Please refer to the following: Figure 5 Based on the precision CNC machine tool rotary table provided in the first embodiment of this application, the second embodiment of this application proposes another precision CNC machine tool rotary table.

[0047] Specifically, the second embodiment of this application provides a precision CNC machine tool rotary table in that, in a precision CNC machine tool rotary table, both ends of the bottom of the sliding seat 3 are fixedly installed with mounting frames 6, the inner side of the mounting frame 6 is provided with a connecting plate 62, the bottom of the connecting plate 62 is fixedly installed with a cleaning brush 63, and the bottom of the cleaning brush 63 is attached to the bottom of the inner side of the feed trough 12.

[0048] Both ends of the mounting frame 6 are threaded with locking screws 61, one end of which abuts against the side of the connecting plate 62.

[0049] When it is necessary to disassemble the sweeping brush 63, the user can turn the locking screw 61 so that one end of the locking screw 61 is away from the connecting plate 62, and then the connecting plate 62 can be removed from the inner side of the mounting frame 6, thereby disassembling the sweeping brush 63.

[0050] The working principle of the precision CNC machine tool rotary table provided by this utility model is as follows:

[0051] When in use, the sliding seat 3 moves back and forth, which enables the cleaning brush 63 to move back and forth on the inner side of the feeding trough 12, thereby pushing and collecting the slag on the inner side of the feeding trough 12, which makes it convenient for the user to process the slag later.

[0052] Compared with related technologies, the precision CNC machine tool rotary table provided by this utility model has the following beneficial effects:

[0053] The mounting frame 6, locking screw 61, connecting plate 62 and cleaning brush 63 work together to enable the sliding seat 3 to drive the two cleaning brushes 63 to move on the inner side of the feeding trough 12 during use, pushing and collecting the slag on the inner side of the feeding trough 12, which is convenient for users to process later.
