Compared with the horizontally set slide, the cradle turntable can cooperate with the machining spindle to form multi-axis linkage machining, thereby realizing a variety of machining processes for three-dimensional complex surfaces.

[0003] With the rapid development of modern industry, the types, shapes, precision and efficiency requirements of processed materials are constantly increasing, which puts forward higher demand standards for processing machine tools. The processing of materials often requires multiple processes. The special nature of traditional machine tools requires each process to be completed on multiple machine tools. Multiple clamping affects the processing quality and precision, and it is difficult to ensure processing efficiency. Therefore, CNC machine tools that integrate laser processing and tool processing are continuously developed, that is, the laser mechanism and tool processing mechanism are arranged in a front-to-back manner on the bed of the CNC machine tool. In order to be able to cooperate with the laser mechanism and the tool processing mechanism at the same time, the cradle turntable is driven to move forward and backward through the X-axis drive mechanism.

The machine tool is only partially assembled before shipment from the factory, and the slide is not connected to the X-axis drive mechanism. Therefore, the slide and the cradle turntable on the slide can slide freely. Therefore, during the transportation of the CNC machine tool, the cradle turntable will shake violently from side to side, and may even move out of the X-axis guide rail, collide with other mechanisms, and cause damage. Therefore, in order to protect the cradle turntable, it is urgent to fix the cradle turntable before transporting the CNC machine tool. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model provides a cradle turntable transport fixing structure. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0022] In this article, the X-axis direction is the front-to-back direction, the Y-axis direction is the left-to-right direction, and the Z-axis direction is the up-down direction.

[0023] See also Figure 1-Figure 4 The utility model provides a cradle turntable 2 transportation fixing structure, including a slide 1 slidably arranged on a machine tool bed 51 along the X-axis, a cradle turntable 2 arranged on the slide 1, the cradle turntable 2 including a turntable 21, a receiving seat 22 arranged on one side of the turntable 21 and rotatably connected to the turntable 21, and a drive box 23 arranged on the other side of the turntable 21 and drivingly connected to the turntable 21, a stop bracket 3 is provided on the slide 1, and the top of the stop bracket 3 is fixedly connected to the turntable 21 through a first locking screw; a stop seat 4 for limiting the sliding of the slide 1 is provided on the machine tool bed 51. The slide 1 is installed on a CNC machine tool having a laser processing mechanism 53 and a tool processing mechanism 52, and the laser processing mechanism 53 and the tool processing mechanism 52 are arranged front and back.

[0024] When the CNC machine tool is shipped, the CNC machine tool has completed the assembly of the slide 1 and the cradle turntable 2, as well as the sliding assembly of the slide 1 and the X-axis guide rail 54. Since the X-axis drive mechanism 56 and the drive box 23 need to be transported to the destination before transmission debugging, the X-axis drive mechanism 56 does not form a transmission relationship with the slide 1, and the drive box 23 does not form a transmission relationship with the turntable 21. Therefore, the slide 1 and the cradle turntable 2 can move freely along the X-axis, and the turntable 21 on the cradle turntable 2 can swing left and right. In order to limit the self-motion of the slide 1 during transportation, before shipment, the slide 1 is first pulled to the set position, and then the stop seat 4 is used to fix the slide 1, so that the slide 1 and the cradle turntable 2 cannot slide along the X-axis; then the stop bracket 3 is fixedly installed on the slide 1, and then the top of the stop bracket 3 is fixedly connected to the turntable 21 through the first locking screw (not shown in the figure), so that the stop bracket 3 limits the turntable 21 from shaking left and right, which can ensure that the cradle turntable 2 cannot move by itself during transportation, thereby protecting the cradle turntable 2.

[0025] In fact, the turntable 21 on the cradle turntable 2 is in the shape of a gold ingot, that is, the turntable 21 has two symmetrically arranged ears, and the middle of the turntable 21 forms a clamping station; the receiving seat 22 and the driving box 23 have been pre-fixed on the slide 1.

[0026] In order to better limit and fix the turntable 21, specifically, the stop bracket 3 includes a bottom plate 31 and a vertical plate 32 arranged on the bottom plate 31. The vertical plate 32 and the bottom plate 31 are combined to form an L-shaped structure. The vertical plate 32 extends upward so that the vertical plate 32 can be matched and connected with the ear of the turntable 21. A first mounting hole 34 is opened on the top of the vertical plate 32, and more than two second mounting holes 35 are opened on the bottom plate 31. The turntable 21 is provided with the same number of first threaded holes and one-to-one correspondence with the first mounting holes 34. The first threaded holes are opened on the ear of the turntable 21, and the slide 1 is provided with the same number of second threaded holes and one-to-one correspondence with the second mounting holes 35. A first locking screw (not shown in the figure) matching the first threaded hole on the turntable 21 is installed at the first mounting hole 34, and a second locking screw (not shown in the figure) matching the second mounting hole 35 on the slide 1 is installed at the second mounting hole 35. Tightening the first locking screw and the second locking screw can limit the turntable 21 of the cradle turntable 2 from swinging left and right.

[0027] In order to reduce the processing accuracy of the stop bracket 3 and facilitate the manufacture of the stop bracket 3, the first mounting hole 34 is set as a waist-shaped hole extending in the Z-axis direction, and the second mounting hole 35 is set as a waist-shaped hole extending in the Y-axis direction, ensuring that the first locking screw has enough surplus to be installed in conjunction with the turntable 21, and the second locking screw has enough surplus to be installed in conjunction with the slide 1, so as to facilitate installation.

[0028] In order to improve the structural strength of the stop bracket 3 and prevent the bottom plate 31 and the vertical plate 32 from being deformed, the inner corners formed by the bottom plate 31 and the vertical plate 32 are reinforced and connected by a first corner plate 33 .

[0029] Preferably, more than two stop brackets 3 are provided to provide better limiting capability for the turntable 21 . In the present embodiment, two stop brackets 3 are provided, and the two stop brackets 3 are connected and fixed to the two ears of the turntable 21 .

[0030] In fact, a guide rail 54 extending along the X-axis is provided on the machine tool bed 51, and the bottom of the slide 1 is slidably connected to the X-axis guide rail 54 through a slider 55.

[0031] Specifically, the stopper 4 includes a seat plate 41 and an ear plate 42 disposed on the seat plate 41, the ear plate 42 is provided with more than two third mounting holes 44, the side surface of the slide 1 is provided with third threaded holes of the same number and one-to-one correspondence as the third mounting holes 44, the seat plate 41 is provided with more than two fourth mounting holes 45, and the machine tool bed 51 is provided with fourth threaded holes of the same number and one-to-one correspondence as the fourth mounting holes 45. A third locking screw (not shown in the figure) matching the third threaded hole on the slide 1 is installed at the third mounting hole 44, and a fourth locking screw (not shown in the figure) matching the fourth mounting hole 45 on the machine tool bed 51 is installed at the fourth mounting hole 45. By tightening the third locking screw and the fourth locking screw, the slide 1 can be fixed to limit the forward and backward movement of the slide 1 and the cradle turntable 2.

[0032] In order to strengthen the fixation of the slide 1 , a stop seat 4 is provided at each corner of the slide 1 .

[0033] In order to reduce the processing accuracy of the stop seat 4 and facilitate the manufacture of the stop bracket 3, the third mounting hole 44 is a waist-shaped hole extending in the Z-axis direction, and the fourth mounting hole 45 is a waist-shaped hole extending in the Y-axis direction, ensuring that the third locking screw has enough surplus to be installed in conjunction with the slide 1, and the fourth locking screw has enough surplus to be installed in conjunction with the machine tool bed 51, so as to facilitate installation.

[0034] In order to improve the structural strength of the stop seat 4 and prevent the seat plate 41 and the ear plate 42 from being deformed, the inner corners formed by the seat plate 41 and the ear plate 42 are reinforced by a second angle plate 43 .
