Description

Technical Field

[0001] The utility model belongs to the technical field of artificial joint coating preparation, and more specifically, particularly relates to a planetary turntable used for artificial joint coating preparation. Background Art

[0002] Artificial joint coating preparation refers to the process of coating a layer of specific material on the surface of artificial joints, aiming to improve the performance and durability of artificial joints. The planetary turntable is a base system used in vacuum deposition equipment, mainly used to rotate and control the substrate during physical vapor deposition (PVD) process.

[0003] When some of the planetary turntables currently used for preparing artificial joint coatings are in use, the staff needs to place the artificial joint directly on the planetary turntable. When the planetary turntable rotates and when some coating spraying equipment is spraying, the rotation of the planetary turntable and the blowing of the airflow can easily cause the artificial joint to shake or even fall off the planetary turntable, thereby causing damage to the artificial joint and increasing production costs.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a planetary turntable for the preparation of artificial joint coating is provided, in order to achieve a more practical purpose. Utility Model Content

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] Example:

[0024] As attached Figure 1 To Attachment Figure 4 As shown:

[0025] The utility model provides a planetary turntable for preparing artificial joint coatings, comprising a planetary turntable body 1, three arc-shaped mounting seats 2 are equidistantly installed on the circumferential side of the top end of the planetary turntable body 1, an arc-shaped sliding groove 3 is provided on the top end of the arc-shaped mounting seat 2, an arc-shaped sliding block 4 is slidably installed in the arc-shaped sliding groove 3, a first threaded rod 5 is threadedly connected at the middle position of the arc-shaped sliding block 4, the three first threaded rods 5 are rotatably installed with extrusion blocks 6 at one end close to each other, a second threaded rod 7 is installed at the bottom end of the arc-shaped sliding block 4 on a side away from the planetary turntable body 1, a locking block 8 is threadedly connected to the circumferential side of the second threaded rod 7, the arc-shaped mounting seat 2 is provided with a second sliding groove 9 on the side away from the planetary turntable body 1, and a collecting mechanism is installed at the middle position of the planetary turntable body 1.

[0026] Among them, the bottom end of the extrusion block 6 is in close contact with the top of the planetary turntable body 1. When the staff rotates the first threaded rod 5 through the knob 12, the first threaded rod 5 rotates and moves at the middle position of the arc-shaped slider 4. Since one end of the first threaded rod 5 is rotatably connected to the extrusion block 6, and the bottom end of the extrusion block 6 is in close contact with the top of the planetary turntable body 1, the first threaded rod 5 can push the extrusion block 6 to move, so that the staff can adjust the positions of the three extrusion blocks 6 according to the shapes and sizes of different artificial joints.

[0027] The three extrusion blocks 6 are all provided with a buffer pad 10 on the side close to each other, so as to reduce the damage caused by the direct contact between the artificial joint and the extrusion block 6 .

[0028] Among them, the second threaded rod 7 is slidably connected with the second slide groove 9, so that the second threaded rod 7 can slide in the second slide groove 9, so that the staff can move the three arc-shaped sliders 4 to appropriate positions according to the specific shape and size of the artificial joint, and then rotate the locking block 8 so that one side of the locking block 8 is tightly attached to one side of the arc-shaped mounting seat 2, thereby fixing the arc-shaped slider 4.

[0029] Among them, the locking block 8 is installed with an anti-skid pad 11 on one side close to the second sliding groove 9 to increase the friction between the locking block 8 and the arc-shaped mounting seat 2 and improve the stability of the arc-shaped sliding block 4 after being fixed.

[0030] A knob 12 is installed at the other end of the first threaded rod 5 to facilitate the rotation of the first threaded rod 5 so that the first threaded rod 5 can rotate and move at the middle position of the arc-shaped slider 4 .

[0031] Among them, the collecting mechanism includes a collecting box 13, which is installed on the circumferential side at the middle position of the planetary turntable body 1. An air inlet 14 is installed at the top of the collecting box 13, and the air inlet 14 is funnel-shaped. A filter 15 is installed at the middle position inside the collecting box 13, and an air pump 16 is installed at the bottom end of the collecting box 13. An exhaust port 17 is provided at the bottom end of one side of the collecting box 13 at a position close to the output end of the air pump 16. When preparing the artificial joint coating, if the coating is in powder form, the staff can turn on the air pump 16 to make the air pump 16 discharge the air inside the collecting box 13 from the exhaust port 17, thereby instantly generating negative pressure in the collecting box 13. At this time, the air and powder outside the collecting box 13 enter the collecting box 13 from the air inlet 14 and adhere to the filter 15, thereby collecting excess powder.

[0032] The working principle of this embodiment: when using the planetary turntable for preparing coatings for artificial joints, the staff first places the artificial joint that needs to be coated near the middle position of the top of the planetary turntable body 1, and then slides the three arc-shaped sliders 4 according to the shape and size of the artificial joint. The movement of the arc-shaped sliders 4 drives the extrusion block 6 to be moved to a suitable position so that the extrusion block 6 can be close to the artificial joint. After moving the arc-shaped slider 4 to a suitable position, the staff rotates the three locking blocks 8 respectively, so that the locking block 8 rotates and moves around the second threaded rod 7, and then fits tightly against one side of the arc-shaped mounting seat 2 to lock the arc-shaped slider 4. After the locking is completed, the staff rotates the knob 12 to rotate and move the first threaded rod 5 at the middle position of the arc-shaped slider 4. Since one end of the first threaded rod 5 rotates with the extrusion block 6 The first threaded rod 5 can push the extrusion block 6 to move, so that the staff can adjust the positions of the three extrusion blocks 6 according to the shapes and sizes of the artificial joints, so that the three extrusion blocks 6 can be tightly attached to the artificial joints. If the artificial joint is relatively fragile, the staff can control the extrusion block 6 to move to a position close to the artificial joint, so that the three extrusion blocks 6 can limit the artificial joint. In addition, if the coating is in powder form, the staff can turn on the air pump 16 to discharge the air inside the collection box 13 from the exhaust port 17, thereby instantly generating negative pressure in the collection box 13. At this time, the air outside the collection box 13 and the powder enter the collection box 13 from the air inlet 14 and adhere to the filter screen 15, so as to collect excess powder.

Many modifications and variations will be apparent to those of ordinary skill in the art.
