Description

Technical Field

[0001] This utility model relates to the field of casting technology, and more specifically, it relates to a general casting flipping tool. Background Technology

[0002] Foundry companies need to clean the surface of castings by removing burrs, pinholes, etc. The first cleaning process is currently done manually.

[0003] Workers often use hooks or crowbars to flip castings during the cleaning of internal and external burrs, pores, and other defects. However, traditional hooks have a fixed opening size, which makes it difficult to flip castings of varying shapes, textures, and thicknesses. This often results in castings falling off the hook or the hook rebounding and causing injuries. Using crowbars for flipping castings is only suitable for light and small castings. When dealing with large and heavy castings, the crowbars are insufficient, leading to difficulties in flipping and low production efficiency. In severe cases, a slight mishap can result in the crowbar rebounding and causing injury. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a universal casting flipping tool that addresses the above-mentioned shortcomings of the existing technology. It is simple to operate, effectively improves production efficiency, and has a high degree of firmness in connection with the casting, effectively ensuring the safety and reliability of the operation process and preventing the occurrence of safety accidents.

[0005] The technical solution of this utility model is as follows: A general casting flipping tool includes a U-shaped body. The upper horizontal arm of the U-shaped body is provided with a mounting hole extending and penetrating the lower horizontal arm. A retaining pin sleeve is inserted into the mounting hole. The retaining pin sleeve is provided with a retaining pin hole. A tensioning retaining pin is slidably inserted into the retaining pin hole. The outer wall surface of the tensioning retaining pin is provided with multiple annular grooves arranged at equal intervals along its axial direction. The tensioning retaining pin corresponding to the annular grooves is provided with an axially arranged longitudinal groove, and the longitudinal groove is connected to the multiple annular grooves. A rotatable pull ring is provided on the tensioning retaining pin above the retaining pin sleeve. A threaded hole is provided on the retaining pin sleeve above the upper horizontal arm of the U-shaped body. A guide screw is threaded into the threaded hole, and one end of the guide screw is inserted into the longitudinal groove. A clamping block is provided at the bottom of the tensioning retaining pin. A tension spring is sleeved on the tensioning retaining pin between the retaining pin sleeve and the clamping block. A rotatable shackle is also provided on the side wall of the U-shaped body.

[0006] As a further improvement, the locking pin hole includes a first through hole and a second through hole. The tensioning locking pin is slidably inserted into the first through hole. The second through hole is located below the first through hole, and the diameter of the first through hole is smaller than the diameter of the second through hole. A stepped surface is formed at the junction of the first through hole and the second through hole. The tension spring is sleeved on the tensioning locking pin between the stepped surface and the pressing block.

[0007] Furthermore, the inner diameter of the tension spring is larger than the diameter of the tensioning pin, and the outer diameter of the tension spring is smaller than the diameter of the second through hole.

[0008] Furthermore, the locking pin between the locking pin sleeve and the pull ring is provided with a retaining spring groove, and an elastic retaining spring is engaged in the retaining spring groove.

[0009] Furthermore, each of the U-shaped bodies on both sides of the mounting hole is provided with a limiting hole extending forward and backward. A cylindrical pin is inserted into the limiting hole. The outer wall of the locking sleeve is provided with two arc-shaped grooves extending forward and backward. When the locking sleeve is inserted into the mounting hole, the two limiting holes and the two arc-shaped grooves are connected one-to-one, and the cylindrical pin is inserted into the corresponding arc-shaped groove.

[0010] Furthermore, a limiting block is provided at one end of the lower horizontal arm of the U-shaped body.

[0011] Beneficial effects

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] This utility model discloses a universal casting flipping tool. A U-shaped body is inserted into a suitable position on the end face of the casting to be flipped. Then, under the action of a tension spring, the clamping block at the bottom of the locking pin presses against the upper end face of the casting. A rotating pull ring drives the locking pin to open and close, causing the guide screw to enter the appropriate position in the annular groove and prevent it from retracting. This ensures that the opening is minimized after the casting is inserted. Then, a hook from a lifting device is used to connect with a shackle, thus completing the casting flipping process. This tool has a simple structure, is easy to operate, and effectively improves work efficiency. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0022] See Figure 1-6 A general-purpose casting flipping tool includes a U-shaped body 1. The upper horizontal arm of the U-shaped body 1 has a mounting hole 3 extending and penetrating the lower horizontal arm. A locking pin sleeve 2 is inserted into the mounting hole 3. The locking pin sleeve 2 has a locking pin hole 4. A tensioning locking pin 5 is slidably inserted into the locking pin hole 4. The outer wall surface of the tensioning locking pin 5 has multiple annular grooves 10 arranged at equal intervals along its axial direction. The tensioning locking pin 5 corresponding to the annular grooves 10 has an axially arranged longitudinal groove 11, and the longitudinal groove 11 communicates with the multiple annular grooves 10. A rotatable... The pull ring 6 and the locking pin sleeve 2 above the upper horizontal arm of the U-shaped body 1 are provided with threaded holes 12. A guide screw 8 is threaded into the threaded hole 12, and one end of the guide screw 8 is inserted into the longitudinal groove 11. The width of the annular groove 10 is greater than the diameter of the guide screw 8. When the guide screw 8 is inserted into the annular groove 10, the opening and closing locking pin 5 can be adjusted slightly up and down. The bottom of the opening and closing locking pin 5 is provided with a pressing block 13. A tension spring 9 is sleeved on the opening and closing locking pin 5 between the locking pin sleeve 2 and the pressing block 13. A rotatable shackle 18 is also provided on the side wall of the U-shaped body 1.

[0023] Preferably, a bolt hole 21 is provided on the side wall of the U-shaped body 1, and a fastening bolt is provided in the bolt hole 21. The fastening bolt passes through the shackle 18 and the bolt hole 21 in sequence and is threadedly connected to the shackle 18, thereby rotating the shackle 18 onto the U-shaped body 1. The diameter of the fastening bolt is slightly smaller than the diameter of the bolt hole 21 to ensure the smoothness of the shackle 18 during the flipping process.

[0024] When a casting needs to be flipped, the worker holds the pull ring 6 and first rotates the tension locking pin 5 to insert the guide screw 8 into the longitudinal groove 11. Then, the worker pulls the tension locking pin 5 to maximize the opening on one side of the U-shaped body 1. At this time, the tension spring 9 is compressed to its limit, locking the U-shaped body 1 into the appropriate position on the end face of the casting to be flipped. Then, the worker releases the pull ring 6, allowing the clamping block 13 at the bottom of the tension locking pin 5 to press against the upper end face of the casting under the action of the tension spring 9. Then, the worker rotates the tension locking pin 5 to insert the guide screw 8 into the corresponding annular groove 10, ensuring that the tension locking pin 5 will not loosen due to external force or other influences during the casting flipping process, causing the casting to fall. Then, the worker uses the hook of the lifting tool to connect with the shackle 2, thereby completing the casting flipping. This tool has a simple structure, is easy to operate, effectively improves work efficiency, and has a high degree of firmness in clamping the casting to be flipped, effectively ensuring the safety and reliability of the operation process and preventing safety accidents.

[0025] In this embodiment, the locking pin hole 4 includes a first through hole 41 and a second through hole 42. The tensioning locking pin 5 is slidably inserted into the first through hole 41. The second through hole 42 is located below the first through hole 41, and the diameter of the first through hole 41 is smaller than the diameter of the second through hole 42. A stepped surface 14 is formed at the junction of the first through hole 41 and the second through hole 42. The tension spring 9 is sleeved on the tensioning locking pin 5 between the stepped surface 14 and the clamping block 13. When the tension spring 9 is sleeved on the tensioning locking pin 5, under the action of the stepped surface 14 and the clamping block 13, the tension spring 9 is always in a compressed state. The tension spring 9 applies a downward pressure to the tensioning locking pin 5, so that the tool further improves the firmness of the connection between the casting and the U-shaped body 1 when clamping the casting.

[0026] In this embodiment, the inner diameter of the tension spring 9 is larger than the diameter of the tensioning and closing pin 5, and the outer diameter of the tension spring 9 is smaller than the diameter of the second through hole 42. The inner diameter of the tension spring 9 is slightly larger than the diameter of the tensioning and closing pin 5, and the outer diameter of the tension spring 9 is slightly smaller than the diameter of the second through hole 42, so that the tensioning and closing pin 5 moves up and down without obstruction, ensuring the smooth sliding of the tensioning and closing pin 5.

[0027] In this embodiment, the tensioning pin 5 between the locking pin sleeve 2 and the pull ring 6 is provided with a retaining spring groove 15, and an elastic retaining spring 7 is engaged in the retaining spring groove 15. When the guide screw 8 is inserted into the longitudinal groove 11, the tensioning pin 5 moves downward under the action of gravity and the tension spring 9, and the elastic retaining spring 7 limits the downward movement of the tensioning pin 5.

[0028] In this embodiment, the U-shaped body 1 on both sides of the mounting hole 18 is provided with a limiting hole 16 extending forward and backward. The two limiting holes 15 are symmetrically distributed on both sides of the mounting hole 3 with the axis of the mounting hole 3 as the reference. A cylindrical pin 19 is inserted into the limiting hole 16. The outer wall of the locking sleeve 2 is provided with two arc-shaped grooves 17 extending forward and backward. When the locking sleeve 2 is inserted into the mounting hole 3, the two limiting holes 16 and the two arc-shaped grooves 17 are connected one-to-one, and the cylindrical pin 19 is inserted into the corresponding arc-shaped groove 17. The two cylindrical pins 19 are inserted one-to-one into the two arc-shaped grooves 17, which can prevent the locking sleeve 2 from moving when the locking pin 5 is stretched or rotated. When the locking sleeve 2 needs to be disassembled, only the two cylindrical pins 19 need to be pulled out to remove the Cassiopeia 2 from the U-shaped body 1, which facilitates the disassembly, assembly, maintenance and repair of the locking sleeve 2.

[0029] In this embodiment, a limiting block 20 is provided at one end of the lower horizontal arm of the U-shaped body 1. When clamping the casting, the lower horizontal arm of the U-shaped body 1 cooperates with the limiting block 20 to fit into the uneven position of the casting end face, further strengthening the firmness of the connection between the casting and the U-shaped body 1.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
