Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, and more specifically, it relates to a multi-layer rotary workpiece holder for vacuum heat treatment. Background Technology

[0002] When processing workpieces, some workpieces require heat treatment, which is done using vacuum heat treatment equipment. In order to ensure that the workpieces are heated evenly, the workpiece holder is designed to be rotatable, so that the workpieces are heated while moving, resulting in more even heating.

[0003] Common workpiece rack structures are relatively simple. The connection between the workpiece rack and the rotation drive of the heat treatment equipment is a corresponding structure, which can only mate with drive shafts of specific sizes. Workpiece racks of different models and different processing equipment are not interchangeable, making them somewhat inconvenient to use. Moreover, the simple structure of the workpiece rack has a fixed placement structure that cannot be adjusted. In order to process more workpieces at once, a multi-layer structure may be set up, but the spacing between the racks cannot be changed. Some larger workpieces may not be able to fit, or this may result in wasted space and low utilization efficiency. In addition, when placing workpieces, depending on the structure of the workpiece, some workpieces are more suitable for hanging placement, while others are more suitable for tethering. Common workpiece rack structures are too simple to adapt to different placement needs, making them inconvenient to use. Utility Model Content

[0022] In this embodiment, the support capacity is provided by the cooperation of the base 1, the rotating column 2, and the support frame 3. When using the equipment, multiple support frames 3 are used to place the workpiece, and the equipment is placed inside the vacuum heat treatment equipment. Then, the rotating column 2 is aligned with the rotating drive shaft of the heat treatment equipment, and the drive shaft is positioned between the clamping blocks 6. The movable groove 4 provides a structure to control the rotation of the rotating screw 5, so that the control screw cooperates with the clamping blocks 6 to provide power, causing the clamping blocks 6 to move. The clamping blocks 6 at both ends move inward to clamp the drive shaft structure and achieve connection. During heat treatment, the rotating column 2 is driven to rotate by the drive equipment. The rotating column 2 rotates with the base 1, and the support frame 3 rotates, so that the workpiece is heated more evenly.

[0023] More specifically, the sliding ring 7 provides the mounting structure, moves the support frame 3, and moves the sliding ring 7 along the sliding groove 9 via the sliding block 8. The height of the sliding ring 7 can be adjusted so that the sliding block 8 is aligned with the support groove 10. Rotating the sliding ring 7 causes the sliding block 8 to slide into the support groove 10, thereby limiting the height of the sliding ring 7. The sliding ring 7 moves the support frame 3, thereby adjusting the height and spacing of the multiple support frames 3.

[0024] Please see Figure 1 As one implementation of the support adaptation: the support frame 3 includes a hanger 11 and a bracket 12. The hanger 11 is provided with a support hook 13, and the bracket 12 is provided with a support net 14.

[0029] Specifically, multiple support bars 18 cooperate with the support rings 19 at the outer ends to provide support capacity, enabling the support net 14 to stably place the workpiece.

[0030] Please see Figure 5 As a further embodiment of the rotating column: a wheel groove 20 is provided on the rotating column 2, and a control wheel 21 is provided in the wheel groove 20. The control wheel 21 cooperates with the rotating screw 5.

[0031] Specifically, the structure is provided by the wheel groove 20. By rotating the control wheel 21, the control wheel 21 is rotated, which drives the rotating screw 5 to rotate, thereby adjusting the clamping block 6.

[0032] Please see Figure 5 As a further embodiment of the clamping block: the clamping block 6 is provided with limiting sliders 22 at both ends, and the movable groove 4 is provided with limiting grooves 23, and the limiting sliders 22 cooperate with the limiting grooves 23.

[0033] Specifically, by restricting the slider 22 and the sliding groove 23, the movement of the clamping block 6 is made more stable.

[0034] Please see Figure 5 As a further embodiment of the clamping block 6: the inner side of the clamping block 6 is provided with anti-slip texture 24.

[0035] Specifically, the anti-slip texture 24 provides an anti-slip effect, facilitating a stable fit between the clamping block and the shaft.

[0036] Please see Figure 2 As a further embodiment of the support groove 10: the support groove 10 includes a sliding groove 25 and a recessed groove 26, with the recessed groove 26 disposed below the sliding groove 25.

[0037] Specifically, the sliding block 8 is made to slide into the sliding groove 25, and then the sliding block 8 is made to move downward into the recessed groove 26. The recessed groove 26 restricts the sliding block 8 and prevents the sliding ring 7 from rotating.

[0038] In summary, when the overall equipment is in use (or running): The base 1, rotating column 2, and support frame 3 provide support. When using the equipment, multiple support frames 3 are used to place the workpiece. The equipment is placed inside the vacuum heat treatment equipment, and then the rotating column 2 is aligned with the rotating drive shaft of the heat treatment equipment, so that the drive shaft is located between the clamping blocks 6. The wheel groove 20 provides the structure. The control wheel 21 is rotated, which drives the rotating screw 5 to rotate. The movable groove 4 provides the structure for adjusting the position of the clamping blocks 6. The rotating screw 5 cooperates with the clamping blocks 6 to provide power and drive the clamping blocks 6 at both ends to move inward. The limiting slider 22 cooperates with the limiting groove 23 to make the movement of the clamping blocks 6 more stable. The anti-slip texture 24 provides an anti-slip effect, so that the clamping blocks contact the shaft of the drive equipment and clamp the drive shaft structure to achieve connection. During heat treatment, the drive equipment drives the rotating column 2 to rotate. The rotating column 2 rotates with the base 1, and the support frame 3 rotates, so that the workpiece is heated more evenly.

[0039] Select support frame 3 according to usage requirements. With the cooperation of hanger 11 and support hook 13, the hanger 11 provides support. The hanging hole 15 provides the installation structure. One end of the hook passes through the hanging hole 15, and the other end is used to hang the workpiece. Install support hook 13 at different hanging holes 15 according to requirements. Adjust the position and number of support hook 13 to meet the hanging of different workpieces and avoid collision between workpieces. Hang the workpiece on the support hook 13. The bracket 12 provides support capacity. Multiple support bars 18 cooperate with the outer support ring 19 to provide support capacity. The support net 14 is set on the bracket 12 to stably place the workpiece. The support net 14 supports the workpiece and provides different workpiece placement methods to meet the placement requirements of different workpieces.

[0040] When arranging the support frame 3, the sliding ring 7 provides the installation structure. Moving the support frame 3, the sliding ring 7 moves along the sliding groove 9 via the sliding block 8, and the sliding ring 7 is fitted onto the rotating column 2. The height of the sliding ring 7 is adjusted so that the sliding block 8 is aligned with the corresponding support groove 10. The sliding ring 7 is rotated so that the sliding block 8 slides into the support groove 10. The sliding groove 25 facilitates the sliding of the sliding block 8. Then, the sliding block 8 moves downward into the recessed groove 26, which restricts the sliding block 8 and prevents the sliding ring 7 from rotating during subsequent processing. The installation of the support frame 3 is completed. Appropriate hangers 11 and brackets 12 can be arranged in different positions as needed. After processing is completed, the sliding ring 7 can be directly disassembled, and the support frame 3 can be removed directly without contacting the workpiece. Other sets of support frames 3 and sliding rings 7 are installed on the rotating column 2 for subsequent work.
