Description

Technical Field

[0001] The invention relates to the technical field of precision parts processing, in particular to a precision parts mounting assembly. Background Art

[0002] When surface polishing is performed on thin circular precision parts, the thin circular precision parts are accurately mounted on a workbench through suction cups at multiple different positions to prevent displacement of the thin circular precision parts during the polishing process.

[0003] During the processing and manufacturing process of thin circular precision parts, warping may occur on the surface of the parts due to differences in material properties and thermal expansion coefficients or stress caused by the manufacturing process. The main warping forms are bow warping and dish warping. Bow warping means that the center of the chip is relatively high and the overall shape is similar to a bow. Disk warping means that the center is relatively low and the overall shape is similar to a dish, which is the opposite of bow warping. In addition, due to the complexity of material properties and the precision requirements of process control, it is difficult to completely eliminate the warping of thin circular precision parts. Therefore, when processing thin sheets, the warping of the parts is often very complicated. When surface polishing is performed on circular precision parts, if each suction cup has the same suction force on thin circular precision parts, the thin circular precision parts will not be able to fit completely with the suction cups due to the existence of warping, making the surface to be processed of the thin circular precision parts appear uneven on the suction cups. At the same time, due to the small polishing allowance, it is difficult to achieve polishing uniformity for the thin circular precision parts during the polishing process, thereby affecting the polishing quality of the thin circular precision parts. For this reason, we propose a precision parts mounting assembly. Summary of the invention

[0053] It should be noted here that: by setting the driving assembly, it is convenient to drive each second suction pipe 202 to adjust and move synchronously, thereby adapting to the adsorption and installation of thin circular precision parts of different sizes.

[0054] It is worth noting that the model of motor 1206 is Y160M1-2, which is a prior art and will not be described in detail here.

[0055] Working principle: When surface polishing is performed on thin circular precision parts, the spacing between the second straws 202 is first adjusted according to the outer diameter of the thin circular precision parts. During the adjustment, the motor 1206 is started to drive the driving rod 1204 to rotate. During the rotation of the driving rod 1204, the two gears 1205 are synchronously driven to rotate. When one of the two gears 1205 is meshed with the gear ring 1202 for transmission, the remaining driving rods 1204 are driven to rotate, thereby realizing the use of one motor 1206 to drive the rotation of each gear 1205. In the process of synchronous rotation of each gear 1205, each rack 1203 is driven to move synchronously through the meshing transmission of the gear 1205 and the rack 1203, so that the distance between each second straw 202 is adjusted under the pushing action of each rack 1203 and the guiding action of the first moving component. When the distance between each second straw 202 is adjusted to facilitate the placement of thin circular precision parts, the rotation of the motor 1206 can be stopped. At this time, the thin circular precision parts can be placed at one end of the first straw 201 and each second straw 202;

[0056] After placing the thin circular precision parts on the first straw 201 and one end of each second straw 202, the motor 1206 is started again, thereby driving each moving plate 402 to approach each other. In the process of each moving plate 402 approaching each other, each sliding plate 501 will be driven to move synchronously. In the process of each sliding plate 501 moving close to the thin circular precision parts, the rotating balls 605 on the mounting rods 604 on one side of each sliding plate 501 will abut against the end faces of the thin circular precision parts before the thin circular precision parts. Then, under the elastic pressing action of the rotating balls 605, the thin circular precision parts are pressed against the end faces of the first straw 201 and the second straw 202. Therefore, under the downward pushing and pressing action of each rotating ball 605, the risk of the thin circular precision parts being placed deflecting and tilting is reduced, thereby ensuring the accuracy of the placement position of the thin circular precision parts.

[0057] When each sliding plate 501 continues to approach the thin circular precision parts, the positioning plates 503 on one side of each sliding plate 501 will abut against the side wall of the thin circular precision parts, so that under the elastic pressing action of each positioning plate 503, both the initial pre-tightening of the thin circular precision parts and the centering of the thin circular precision parts can be achieved, thereby improving the installation positioning accuracy of the thin circular precision parts and the repeated positioning accuracy during batch polishing processing;

[0058] After the thin circular precision parts are preliminarily pre-tightened, the distance from the surface of the thin circular precision parts can be detected by the distance sensors 302 on the side walls of the first suction tube 201 and each second suction tube 202. If the distance of the thin circular precision parts is closer to the first suction tube 201, it means that the warping of the thin circular precision parts is disc-shaped, that is, the center of the thin circular precision parts is relatively low, and the overall shape is similar to a disc. At this time, the controller controls the control valve 303 so that the gas pressure on the side wall of the first suction tube 201 is smaller than the gas pressure of the second suction tube 202, while the gas pressure of each second suction tube 202 is slightly larger, thereby reducing the suction force on the center part of the thin circular precision parts and increasing the suction force on the surrounding parts of the thin circular precision parts. If the distance of the thin circular precision parts is closer to the second suction tube 202, it means that the thin circular precision parts The warping degree is an arch-shaped warping, that is, the center of the thin circular precision component is relatively high, and the overall shape is similar to an arch. At this time, the controller controls the control valve 303 so that the gas pressure of the first suction pipe 201 is slightly larger than the pressure of each second suction pipe 202, and the gas pressure of each second suction pipe 202 is slightly smaller, thereby increasing the suction force on the center part of the thin circular precision component and reducing the suction force on the surrounding part of the thin circular precision component, thereby facilitating the adaptive change of the suction force on the center part and the surrounding part of the thin circular precision component according to the warping shape of the thin circular precision component, thereby improving the fitting effect between the thin circular precision component and the first suction pipe 201 and the second suction pipe 202, thereby improving the surface processing uniformity of the thin circular precision component during the polishing process, reducing the polishing error, and thus improving the polishing quality of the thin circular precision component;

[0059] And in the process of the vacuum pump adsorbing the thin circular precision parts through each second suction pipe 202, when the vacuum adsorption force is transmitted from each second suction pipe 202 to the surface of the thin circular precision parts, the moving ball 1002 will move close to the mesh plate 1003 under the action of suction and the guiding action of the telescopic component. In the process of the moving ball 1002 moving close to the mesh plate 1003, the pushing rod 802 will be pushed to move close to the pushing plate 805, and then under the continuous pushing action of the pushing rod 802, the pushing plate 805 will move away from the second suction pipe 202, and then the sliding plate 501 will be driven to move away from the thin circular precision parts through the connecting plate 804, so that the positioning plate 503 and the rotating ball 605 are separated from the thin circular precision parts, thereby providing operating space for the surface polishing of the thin circular precision parts, reducing the interference of the polishing process, and thus improving the comprehensiveness of the polishing process of the thin circular precision parts.
