Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, and in particular to an automatic shell-making line fixture rotation mechanism. Background Technology

[0002] In investment casting (precision casting) process, the shell-making process is the core link that determines the surface quality and dimensional accuracy of the casting. This process uses a fixture to carry the wax pattern or workpiece and sequentially completes operations such as impregnation with refractory slurry, sprinkling sand, drying and curing to form a multi-layered dense shell. During this process, the stability, transmission accuracy and environmental adaptability of the fixture rotation mechanism directly affect the shell uniformity and production efficiency. Therefore, an automatic shell-making line fixture rotation mechanism is used to solve these problems. Traditional fixture rotation mechanisms drive the fixture to rotate through the rotation of gears, thereby achieving a desired production effect.

[0003] Currently, traditional hanging fixture rotation mechanisms are significantly inefficient and complex in the installation and disassembly of hanging fixtures. Specialized tools are required for assistance during disassembly and installation, and the process requires repeated angle adjustments. This not only increases labor maintenance costs but also affects continuous production. When the rotation mechanism is running, the gears drive the hanging fixtures to rotate, which causes them to shake and result in uneven operation of some hanging fixtures, thus generating some scrap and increasing production costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic shell-making line fixture rotation mechanism, which aims to improve the problems of inefficient and complicated fixture assembly and disassembly in the prior art, uneven operation caused by shaking during the rotation process, and high scrap rate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic shell-making line hanging rotating mechanism includes a steel beam, with rollers abutting on both the front and rear sides of the steel beam. A connecting bracket is rotatably connected to the outer side of the rollers. A connecting block is fixedly connected to the opposite side of the connecting bracket. A fixing groove is opened at the bottom of the connecting block. A spring is fixedly connected to the bottom inner side of the connecting block. A connecting rod one is slidably connected to the inner side of the connecting block. Multiple evenly distributed fixing strips are fixedly connected to the top outer side of the connecting rod one. A connecting rod two is rotatably connected to the bottom of the connecting rod one. A rotating groove is opened at the top of the connecting rod two. A gear is fixedly connected to the bottom of the connecting rod two. An installation hole is opened at the top of the gear. A hook is slidably connected to the bottom of the gear. Multiple nuts are threadedly connected to the outer periphery of the top of the hook.

[0007] As a further description of the above technical solution:

[0008] Support legs are fixedly connected to the left and right sides of the steel beam, and fixed brackets are fixedly connected to the top left and right sides of the steel beam. Limit plates are fixedly connected to the bottom of the fixed brackets, and multiple evenly distributed mounting plates are fixedly connected to the bottom of the fixed brackets. The mounting plates are rotatably connected to a rotating shaft on one side of the opposite side, and a track is sleeved on the outer circumference of the rotating shaft.

[0010] The fixed bracket is fixedly connected to the opposite side of the support leg, the limiting plate is fixedly connected to the opposite side of the support leg, and the mounting plate is fixedly connected to the opposite side of the support leg.

[0011] As a further description of the above technical solution:

[0012] The limiting plate abuts against the top of the gear, and the track is engaged with the outer periphery of the gear;

[0022] 1. In this utility model, the elastic structure of spring, fixing groove and fixing strip realizes quick installation and disassembly of the hanger. When installation is required, simply slide the connecting rod one upward along the fixing groove, squeeze it to the top and then rotate it 90 degrees to complete the installation. Through the elasticity of the spring, the connecting rod one can be firmly locked in the fixing groove. When disassembly is required, simply squeeze the connecting rod one upward to the spring, then rotate it 90 degrees and pull it downward, which reduces the cost of manual maintenance and the loss during downtime.

A connecting bracket 3 is rotatably connected to the outer side of the rollers 2. A connecting block 4 is fixedly connected to one side of the connecting bracket 3, connecting the connecting block 4 and the rollers 2. The connecting block 4 is the core mounting carrier of the fixture, enabling rapid connection between the fixture and the moving component. A fixing groove 6 is formed at the bottom of the connecting block 4, and a spring 5 is fixedly connected within the fixing groove 6. A spring 5 is also fixedly connected to the bottom inner side of the connecting block 4, providing stability for the fixture installation. A connecting rod 7 is slidably connected to the inner side of the connecting block 4. The fixing groove 6 provides installation space for the connecting rod 7, spring 5, and fixing bar 8, allowing connection between the fixture and the moving component via the connecting rod 7. The spring 5 abuts against the top of the connecting rod 7, which is slidably connected within the fixing groove 6. The top is fixedly connected with multiple evenly distributed fixing strips 8. The fixing strips 8 can provide a stable connection and load-bearing capacity for the hanger through the fixing grooves 6. The fixing strips 8 are slidably connected in the fixing grooves 6. The bottom of the connecting rod 1 7 is rotatably connected to the connecting rod 2 9. The connecting rod 2 9 and the connecting rod 1 7 can be rotated through the rotating groove 10. The top of the connecting rod 2 9 has a rotating groove 10. The connecting rod 1 7 is rotatably connected in the rotating groove 10. The bottom of the connecting rod 2 9 is fixedly connected to the gear 11. The gear 11 is the core component for rotation. The top of the gear 11 has a mounting hole 12. The bottom of the gear 11 is slidably connected to the hook 13. The hook 13 can be fixed on the gear 11 through the mounting hole 12. The hook 13 is used to suspend the product to be processed. The top of the left and right sides of the hook 13 is threaded. The outer circumference of the top of the hook 13 is threaded with multiple nuts 14. The upper and lower spacing of the hook 13 can be adjusted through the nuts 14. At the same time, the nuts 14 are also the components for fixing the hook 13. The nuts 14 abut against the top and bottom of the gear 11.

[0033] Reference Figure 1 and Figure 4Support legs 15 are fixedly connected to the left and right sides of the steel beam 1. These support legs 15 are the supporting components of the entire mechanism, providing stable support. Fixed brackets 16 are fixedly connected to the top left and right sides of the steel beam 1. These fixed brackets 16 provide mounting and fixing for other components. The fixed brackets 16 are fixedly connected to the opposite side of the support legs 15. A limit plate 18 is fixedly connected to the bottom of the fixed bracket 16. The limit plate 18 ensures that the gear 11 remains stable during rotation, improving the reliability of rotation. The limit plate 18 abuts against the top of the gear 11. 18 is fixedly connected to the opposite side of the support leg 15. The bottom of the fixed bracket 16 is fixedly connected to multiple evenly distributed mounting plates 17. The mounting plates 17 are fixedly connected to the opposite side of the support leg 15. The opposite side of the mounting plates 17 is rotatably connected to the rotating shaft 20. The mounting plates 17 are used to fix the rotating shaft 20 and also provide space for the rotation of the rotating shaft 20. The rotating shaft 20 is fitted with a track 19. The track 19 is the transmission medium of the entire component. The rotation of the attachment can be realized through the track 19 and the gear 11. The track 19 is meshed with the outer circumference of the gear 11.

[0034] Working principle: When the hanger needs to be installed, first pass the threaded section at the top of the hook (13) through the mounting hole 12 at the bottom of the gear (11), and clamp it with the upper and lower nuts (14). The initial connection with the gear (11) can be completed without additional tools. Then, slide the fixing strip (8) on the outside of the connecting rod (7) along the fixing groove (6) of the connecting block (4) and insert it. When it reaches the top, rotate it 90 degrees. The spring (5) generates a downward squeezing force due to compression, which pushes the fixing strip (8) at the top of the connecting rod (7) to fit tightly against the inner wall of the fixing groove (6) to form a stable support. When it needs to be disassembled, push the connecting rod (7) upward and then rotate it 90 degrees downward to remove the hanger. When the track 19 rotates and drives the gear 11 to rotate, the limiting plate 18 abuts against the gear 11, so that it can fix the gear 11 and will not affect the rotation of the gear 11.
