Description

Technical Field

[0001] This utility model belongs to the field of casting processing fixture technology, specifically a tooling fixture for casting processing. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling, it is processed by grinding and other subsequent processing methods to obtain an object with a certain shape, size and performance. Because castings need to be fixed during processing, whether due to their own weight or the power generated by the machine during processing, in order to ensure the safety of the workers and the processing effect of the casting itself. However, some existing fixtures are either unable to freely adjust the size of the fixture or can only adjust the direction with certain limitations. For example, they can only accommodate castings with a fixed length but can adjust the width, or they can only accommodate castings with a fixed width but can adjust the length. It is impossible to adjust the length and width at the same time.

[0003] Meanwhile, the patent specification with announcement number CN 215616597 U discloses a tooling fixture for precision machining of porous castings, including a base and a tooling table. The tooling table is fixedly connected to the upper surface of the base near the front end. A clamping block is fixedly connected to the upper surface of the tooling table.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5As shown, this utility model provides a tooling fixture for casting processing, including a worktable 1. A motor 2 is fixedly installed on the top inner side of the worktable 1. A double-grooved wheel 3 is fixedly installed at the end of the motor 2's spindle. Multiple transmission belts 4 are rotatably installed on the outer side of the double-grooved wheel 3. A single-grooved wheel 5 is rotatably installed on the other side of one transmission belt 4. A forward-threaded shaft 6 is fixedly installed inside the single-grooved wheel 5. A reverse-threaded shaft 7 is fixedly installed on the other side of the forward-threaded shaft 6. A clamping block 9 is threadedly connected to the outer side of the reverse-threaded shaft 7. A sliding block 8 is fixedly installed on the top surface of the clamping block 9. A base 10 is slidably installed on the bottom surface of the clamping block 9. The seat 10 fits against the worktable 1. The outer thread of the forward threaded shaft 6 is connected to another clamping block 9. The motor 2 drives the double grooved wheel 3, which drives the transmission belts 4 on both sides. The transmission belts 4 drive the single grooved wheel 5, which drives the forward threaded shaft 6. The forward threaded shaft 6 drives the reverse threaded shaft 7. When the forward threaded shaft 6 and the reverse threaded shaft 7 rotate, they drive the clamping block 9 on the top of the sliding block 8 to move inward at the same time, thereby clamping the casting fixture. This adapts to casting fixtures of different thicknesses, avoids the problem of the casting fixture size not matching the fixture, and also improves work efficiency and saves working time.

[0023] Specifically, protective shells 22 are fixedly installed on both sides of the workbench 1, and the double grooved wheel 3 and its associated components work inside the protective shell 22. The protective shell 22 is used to protect the double grooved wheel 3 and its associated components, as well as the safety of external personnel.

[0024] Furthermore, a processing platform 19 is fixedly installed on the inner top surface of the workbench 1, and the motor 2 is located inside the processing platform 19. The processing platform 19 is used to place the castings to be processed, and also protects the motor 2.

[0025] Furthermore, multiple jacks 11 are fixedly installed on the inner bottom of the workbench 1. A flat plate 12 is fixedly installed on the top of the jacks 11. A sliding sleeve 13 is fixedly installed on the outer side of the flat plate 12. A fixed seat 14 is fixedly installed on the top of the sliding sleeve 13. A moving wheel 15 is rotatably installed on the outer side of the fixed seat 14, and the moving wheel 15 is in contact with the transmission belt 4. When the casting is short, the jacks 11 can be opened, and two jacks 11 can be simultaneously installed on the flat plate 12, thereby driving multiple sliding sleeves 13 to move together. When the sliding sleeves 13 move further, they drive the moving wheel 15 through the fixed seat 14. The moving wheel 15 then pulls the outer single groove wheel 5 and its associated components inward through the transmission belt 4, thereby adjusting the distance between the clamping blocks 9 on both sides, so as to clamp the casting with shorter length, thereby adapting to casting tooling of different lengths, improving work efficiency, saving working time, and increasing the flexibility and versatility of the device.

[0026] It is worth noting that multiple fixed shafts 20 are fixedly installed on both sides of the worktable 1, and the fixed shafts 20 penetrate the base 10. A second spring 21 is sleeved on the outside of the fixed shaft 20. One side of the second spring 21 is fixedly connected to the processing platform 19, and the other side is fixedly connected to the worktable 1. The fixed shafts 20 limit the movement of the base 10 and provide a track, while the second spring 21 is used to support the base 10 and prevent the base 10 from moving when clamped.

[0027] It is worth noting that limit blocks 16 are fixedly provided on both sides of the fixed base 14, and the limit blocks 16 are slidably connected to the worktable 1. The limit blocks 16 limit the fixed base 14 when it slides.

[0028] It is worth mentioning that a sliding shaft 17 is slidably provided at the bottom of the sliding sleeve 13, and the sliding shaft 17 is fixedly connected to the worktable 1. A first spring 18 is sleeved on the outside of the sliding shaft 17, and the top of the first spring 18 is fixedly connected to the sliding sleeve 13 and the bottom is fixedly connected to the worktable 1. The sliding shaft 17 is to provide support when the sliding sleeve 13 slides, while the first spring 18 is used to support the sliding sleeve 13.

[0029] Among them, motor 2 and jack 11 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0030] Working principle:

[0031] Before using a casting machining fixture, firstly, adjust the device according to the size of the casting fixture to better clamp it. Turn on the motor 2 inside the machining platform 19. The motor 2 drives the double grooved wheel 3, which drives the transmission belts 4 on both sides. The transmission belts 4 drive the single grooved wheel 5, which drives the forward threaded shaft 6. The forward threaded shaft 6 drives the reverse threaded shaft 7. When the forward threaded shaft 6 and the reverse threaded shaft 7 rotate, they drive the clamping block 9 on the top of the sliding block 8 to move inward simultaneously, thereby clamping the casting fixture. The base 10 at the bottom of the clamping block 9 is used to maintain the balance of the sliding block 8 during sliding. If the casting is short, the jacks 11 inside the worktable 1 can be turned on. The two jacks 11 simultaneously drive the plate 12, thereby driving multiple sliding sleeves 13 to move together. When the sliding sleeves 13 move further, they drive the moving wheel 15 through the fixed seat 14. The limiting blocks 16 on both sides are used to limit the movement of the casting. The moving wheel 15 pulls the outer single groove wheel 5 and its associated components inward through the transmission belt 4, thereby adjusting the distance between the clamping blocks 9 on both sides to clamp the casting with a shorter length. The sliding shaft 17 provides support for the sliding sleeve 13. The first spring 18 is used to support the sliding sleeve 13. The fixed shaft 20 on the outer side of the processing platform 19 provides a track for the sliding of the base 10. The second spring 21 is used to support the base 10 and prevent it from moving inward during use. The protective shell 22 covers the double groove wheel 3 and its associated components to protect the casting from outside crowds. This utility model can freely adjust the size of the fixture during casting processing to adapt to casting tooling of different thicknesses and lengths, avoiding the problem of mismatch between the casting tooling size and the fixture. It also improves work efficiency, saves working time, and increases the flexibility and versatility of the device.
