Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and in particular relates to a steel pipe tooling for vacuum coating target materials. Background Art

[0002] The target material is a sputtering source used to form various functional thin films in the vacuum coating process. Most of them are circular structures. Currently, in target material processing, in order to facilitate target material forming and subsequent batch cutting, most people choose to use a single-opening steel pipe. The target material is injected into the steel pipe and then it is cooled and formed before processing.

[0003] At present, in the process of target material liquid injection cooling and forming, in order to ensure the stability of the processing, the steel pipe is often clamped and fixed accordingly to ensure the stability of the liquid injection and avoid the steel pipe from tipping over or other situations. However, in the actual production process, the general steel pipe clamping tooling needs to be manually or mechanically released first, and then the loading or unloading cycle is completed, and then clamped again, and then the liquid is injected. This results in low production continuity and cumbersome operation. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1-5 As shown, a steel pipe tooling for vacuum coating target material includes a base 1, a motor 11, a control panel and a liquid injector 12, wherein the motor 11 is arranged at the upper end of the base 1, the liquid injector 12 is arranged at the base 1, and a clamping mechanism drivingly connected to the output shaft of the motor 11 is arranged on the upper side of the base 1;

[0025] The clamping mechanism includes a platform 2, a synchronous ring 3 and a plurality of limiter components. The platform 2 is circular and connected concentrically with the output shaft of the motor 11. The synchronous ring 3 is concentrically arranged with the platform 2 and fixed to the upper end of the base 1. The plurality of limiter components are evenly arranged on the upper end of the platform 2.

[0026] The limiting assembly includes a positioning frame 4, a positioning clamp, an expander and a synchronizer. An installation cavity is opened at the upper end of the platform 2. The positioning frame 4 and the positioning clamp are both arranged in the installation cavity. The expander is arranged at the lower end of the platform 2 and connected to the corresponding positioning clamp. The synchronizer is connected to the expander and abuts and matches with the synchronizer ring 3.

[0027] When the target material is formed, the steel pipe is placed on the clamping mechanism through an external robot arm or manually, wherein the platform 2 in the clamping mechanism is driven by the motor 11, so that several limit assemblies circulate equidistantly through the front side of the base 1, thereby facilitating the loading operation. When the limit assembly is located at the front side of the base 1 to prepare for loading and liquid injection and wait for solidification, the synchronizer in the limit assembly will match the synchronizer ring 3, thereby releasing the push of the telescopic device on the positioning clamp, and then opening the positioning clamp and cooperating with the positioning frame 4 to facilitate the placement or removal of the steel pipe. On the contrary, when the steel pipe is placed and the injection is in progress, the positioning clamp is used to clamp the steel pipe stably to ensure the stability of the injection and operation.

[0028] The installation cavity includes a vertical cavity 41 and two arc cavities 42 connected to each other. The two arc cavities 42 are respectively located on the left and right sides of the vertical cavity 41. The positioning frame 4 is located in the vertical cavity 41. The positioning clamp is composed of two semicircular clamps 43 and corresponds to the two arc cavities 42 respectively. The positioning frame 4 in the vertical cavity 41 has a U-shaped opening structure to facilitate the placement and loading and unloading of steel pipes. The arc cavity 42 is used to cooperate with the storage of the semicircular clamps 43 after opening. The semicircular clamps 43 can match the cylindrical structure of the steel pipe, thereby achieving an effective limiting and clamping stabilization effect.

[0029] The expander includes an induction rod 5, an L-shaped flap 51 and a tension spring 52. A cavity 6 corresponding to the two arc-shaped cavities 42 is formed on the lower side of the platform 2. The induction rod 5 is connected to the corresponding semi-circular clamp 43 and slides into the corresponding cavity 6 on one side. The L-shaped flap 51 is fixedly arranged on the lower side of the corresponding semi-circular clamp 43 and is located between the positioning frame 4 and the side wall of the arc-shaped cavity 42. The tension spring 52 is arranged between the side wall of the arc-shaped cavity 42 and the L-shaped flap 51.

[0030] The synchronizer includes a U-shaped rod 61, a spring 62, a push rod 63 and a guide block 64. The number of the guide blocks 64 is two, and they respectively slide up and down in the two cavities 6. The guide block 64 is integrally in a right triangle shape with the hypotenuse facing the vertical cavity 41 side and slidingly abuts against the corresponding induction rod 5. The two ends of the U-shaped rod 61 are respectively connected to the lower ends of the two guide blocks 64. The spring 62 is arranged between the middle of the U-shaped rod 61 and the lower end of the platform 2. The push rod 63 is fixedly arranged in the middle of the U-shaped rod 61 and slidingly abuts against the upper end of the synchronizing ring 3.

[0031] A notch 31 is formed on the side of the synchronizing ring 3 away from the injector 12. One end of the notch 31 in the advancing direction of rotation relative to the platform 2 is in a chamfered structure.

[0032] When the semi-circular clamp 43 is used for clamping, the push rod 63 in the synchronizer will be blocked by the synchronizing ring 3. At this time, the push rod 63 pushes the guide block 64 to lift upward in the cavity 6 through the U-shaped rod 61, thereby pushing the induction rod 5 to slide toward the vertical cavity 41 side and pushing the semi-circular clamp 43 to approach the steel pipe for clamping. Correspondingly, the tension spring 52 is stretched by the movement of the L-shaped flap 51;

[0033] During blanking and loading, at this time, the push rod 63 corresponds to the notch 31 of the synchronizing ring 3. Through the push of the spring 62, the push rod 63 instantly moves downward and stays in the blank space of the notch 31. At this time, the semi-circular clamp 43 can be opened by the pull of the tension spring 52 to meet the need of taking or loading materials. Finally, through the cyclic rotation of the platform 2, the push rod 63 abuts against the chamfered side of the synchronizing ring 3 again and is gradually guided, so as to use the semi-circular clamp 43 to clamp the steel pipe again.

[0034] The opening degree of the notch 31 relative to the platform 2 is 20° - 100°; expanding the opening can, after blanking, keep moving with the platform 2 until a new steel pipe is placed and then clamped.

[0035] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
