Examples

Referring to fig. 1, 2, 3, 5 and 6, the present embodiment provides a sliding table mechanism, which includes a male table 10 and a female table 20 sliding in cooperation with the male table 10; the public platform 10 is provided with a sliding rail 101 and a through hole positioned on one side of the sliding rail 101; the female table 20 is provided with a sliding chute 201 which is sleeved and slides with the sliding rail 101, and the other surface opposite to the sliding chute 201 is provided with a plurality of cavity grooves 202, the female table 20 is internally provided with an air supply channel 203 which is communicated with all the cavity grooves 202, and the air supply channel 203 forms an air inlet 2031 and an air outlet 2032 on the side surface of the female table 20; the surfaces of the sliding groove 201 and the sliding rail 101 are mirror structures.

In this embodiment, the corresponding blank, i.e. the general outline, for example the rectangular outline, is stamped and forged by means of a die. Furthermore, a numerical control machine is used for milling a surface to remove forging marks and improve the smoothness of the surface so as to improve the accuracy of subsequent processing, so that the rotating speed of a cutter of the numerical control milling machine can be 13000r/s, the feeding speed is 35.6m/min, the feeding amount can be 0.12mm/r, the cut amount is 0.5mm, finish milling processing is carried out by the parameters, a smoother surface can be processed, and allowance can be reserved for later mirror surface processing.

Specifically, when the slide rail 101 of the male table 10 is processed, the rotation speed of the cutter of the numerical control milling machine can be 13000r/s, the feeding speed is 35.6m/min, the feeding amount can be 0.12mm/r, the cut amount is 0.5mm, the smooth surface can be processed by finish milling processing according to the parameters, the allowance can be reserved, so that the cut amount is adjusted to be 0.1mm again for mirror surface processing, and polishing is performed by a high-gloss cutter, so that the surface finish of the track meets Ra=0.35 um.

The mode of the multiple processing of the mirror surface can be as follows: mirror finishing includes pre-machining and finishing, and the diameter of a cutter used for the pre-machining is larger than that of a cutter used for the finishing. I.e. the pre-machining may be turned by a milling cutter with a larger diameter (a milling cutter with a diameter of 10 mm), where the feed speed may be relatively fast, e.g. 400mm/min; the subsequent finishing, i.e. turning by means of a milling cutter with a smaller diameter (6 mm milling cutter), may be performed at a relatively slow feed rate, for example 200mm/min; in order to improve the effect, a milling cutter with smaller diameter (a milling cutter with 4 mm) can be used again, and turning is carried out at a feeding speed of 100mm/min, so that the mirror surface processing of the T-shaped structure is completed.

Further, the male stand 10 is turned by milling, that is, the outline of the male stand 10 is machined, the sliding rail 101 is turned by a milling machine, and then the sliding rail is drilled by a drilling machine, so that the formed through hole 102 can be used for mounting and locking so as to mount the male stand 10. Similarly, the female stand 20 is also machined with the sliding groove 201 and the cavity groove 202, so that the sliding groove 201 and the sliding rail 101 can slide in a matched manner, and the cavity groove 202 can be provided with other accessories, such as a vacuum chuck, a turning tool, a welding head, and the like.

After finishing milling the outer contours of the male stage 10 and the female stage 20, mirror finishing is performed. The mirror surface processing is mainly carried out on the sliding rail 101 and the sliding groove 201, so that the surface smoothness of the sliding rail 101 and the sliding groove 201 is further improved, and meanwhile, the matching precision is improved, and more accurate stroke control can be achieved when the sliding rail and the sliding groove relatively slide; and can work in a relatively severe environment because the surface of the mirror has an anti-corrosion effect.

Specifically, when the male stand 10 and the female stand 20 are matched with the sliding groove 201 through the sliding rail 101, the friction coefficient in the sliding process can be greatly reduced due to the fact that the mirror surface structure is adopted for matching, and meanwhile, the moving gap is improved, so that the cavity groove 202 on the female stand 20 and the products are aligned with high precision, and the adsorption of a plurality of products is guaranteed. The suction cup can be connected in the cavity 202 through threads, sealing is performed through a sealing gasket or a sealing ring, vacuum suction operation is performed through the air supply channel 203 (the air supply channel 203 is communicated with a vacuum pump pipeline through the air inlet 2031 and the air outlet 2032 in a sealing manner, so that the effect of vacuum suction is realized), and the purpose of transplanting products is achieved.

As shown in fig. 1, two through holes 102 are provided in this embodiment, and the two through holes are symmetrically provided on both sides of the slide rail 101. And the through hole 102 is a waist-shaped hole. Therefore, the installation connection can be performed through the through hole 102, and the design of the waist-shaped hole can flexibly adjust the installation position of the mother stage 20, thereby improving the practicability.

As shown in fig. 1, in this embodiment, a first reference plane 103 parallel to the sliding rail 101 is disposed on one side of the public platform 10, and the first reference plane 103 may be a plane, through which the position of the sliding rail 101 is calibrated, so that the mirror structure of the sliding rail 101 is protected, and the practicality is improved.

And a T-shaped structure is formed, so that the male stand 10 and the female stand 20 can be engaged, and the male stand 10 and the female stand 20 can be prevented from being separated in the vertical direction. And the clamping of the cambered surfaces can lead the stress to be more uniform, thereby being beneficial to providing stable mating force.

In the present embodiment, the mirror surface is formed in a serpentine or zigzag shape. Through reciprocating walking, the mirror surface can be cut off timely, so that the mirror surface can not be scratched, or the cutting precision is influenced, and the aim of improving the machining precision is fulfilled.

As shown in fig. 1, after rough milling, the rail 101 of the rail 10 is finish-milled along a processing line, and one side of the rail 10 is turned and milled along the same processing line as the rail 101 to form a first reference plane 103 parallel to the rail 101. After the male stand 10 is fixed, the milling machine is used to process the first reference surface 103 and the slide rail 101 on the same straight line, and the flatness error between the processed first reference surface 103 and the slide rail 101 can be ensured to be 0.1mm. Therefore, the first accurate surface can be used for checking the position of the sliding rail 101, the sliding rail 101 is not damaged, and the practicability is improved.

Further, as shown in fig. 3, in this embodiment, a second reference surface 205 machined in the same line as the chute 201 is provided on the mother stage 20; when the slide rail 101 is engaged with the slide groove 201, the second reference surface 205 is disposed parallel to the first reference surface 103.
