Description

Technical Field

[0001] This utility model relates to the field of turning technology for shaft forgings, and in particular to a turning device for shaft forgings. Background Technology

[0002] Shaft forgings typically require high dimensional accuracy and geometric tolerances. For example, the diameter tolerance of each journal in an engine crankshaft may be within a few micrometers, and there are also strict requirements for geometric tolerances such as cylindricity and coaxiality. These turning machining devices, through high-precision CNC systems and precise mechanical structures, can accurately control the movement trajectory of the cutting tool, ensuring that the machined shaft parts have high dimensional accuracy and small geometric tolerances, meeting the requirements of various high-precision equipment.

[0003] During machining, the shaft forging is usually clamped on the lathe first, ensuring that the axis of the workpiece coincides with the axis of the lathe spindle. Then, the selected tool is installed on the tool post of the lathe, and a preliminary tool setting operation is performed to roughly align the tool tip with the axis of the workpiece. Then, the lathe is started to machine the shaft forging.

[0004] Considering that most existing shaft forging turning equipment generates a lot of chips during processing, and that cleaning these chips often requires separate cleaning equipment or manual cleaning, this not only consumes extra energy but also increases labor and time costs, resulting in low overall processing efficiency. For example, with common traditional turning equipment, processing needs to be paused after turning is completed, and workers need to manually clean up the chips, which disrupts the continuity of the processing flow. Therefore, a turning equipment for shaft forging is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a turning device for shaft forgings, which aims to solve the problem that most existing shaft forging turning devices produce a lot of chips during processing, and cleaning the chips often requires separate equipment or manual operation, which not only consumes extra energy, increases labor and time costs, but also reduces the overall processing efficiency. For example, common traditional turning devices require pausing processing after turning and relying on workers to manually clean up the chips, which seriously affects the continuity of the processing flow.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a turning device for shaft forgings, comprising a base, a threaded rod rotatably connected to the inner surface of the base, a movable seat threadedly connected to the outer surface of the threaded rod, a snap-fit ​​component slidably connected to the inner surface of the movable seat, a bolt rotatably connected to the top of the inner surface of the snap-fit ​​component, the outer surface of the bolt threadedly connected to the top of the outer surface of the movable seat, a push plate slidably connected to the inner surface of the base, a snap-fit ​​block fixedly connected to the top of the outer surface of the push plate, the bottom of the outer surface of the snap-fit ​​component snapping with the outer surface of the snap-fit ​​block, and a cleaning component provided on the inner surface of the base;

[0007] The cleaning assembly includes a baffle gate, the top of the outer surface of the baffle gate is hinged to the left side of the inner surface of the base, the bottom of the outer surface of the baffle gate is fixedly connected to the bottom of the outer surface of the base by a pin, and a handle is fixedly connected to the outer surface of the baffle gate.

[0008] As a further description of the above technical solution:

[0010] As a further description of the above technical solution:

[0011] A guide block is fixedly connected to the outer surface of the push plate, and the outer surface of the guide block is slidably connected to the inner surface of the base.

[0012] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] The snap-fit ​​block has multiple sets.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the snap-fit ​​component and the snap-fit ​​block engage, allowing the moving seat to move to the left while the push plate automatically scrapes the bottom of the inner surface of the base, pushing the debris to the storage chamber. This design eliminates the need for an additional power source or complex operation, effectively improving processing efficiency, preventing debris accumulation from affecting processing accuracy and equipment operation, achieving an organic integration of processing and cleaning functions, and optimizing overall work efficiency.

[0024] 2. In this utility model, the snap-fit ​​component engages with snap-fit ​​blocks at different positions, allowing for flexible adjustment of the distance the moving seat drives the push plate to move according to actual needs. When faced with differences in the amount of debris generated in different processing scenarios, or when the distribution range of debris differs after processing shaft forgings of different specifications, the cleaning stroke of the push plate can be precisely controlled, ensuring comprehensive and efficient debris removal. This improves the adaptability of the device to diverse working scenarios and enhances the practicality and versatility of the equipment. Attached Figure Description

[0031] 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.

[0032] Reference Figure 1 , Figures 3-4 This utility model provides an embodiment of a turning device for shaft forgings, comprising a base 1, a threaded rod 9 rotatably connected to the inner surface of the base 1, allowing the threaded rod 9 to rotate along the inner surface of the base 1, a movable seat 2 threadedly connected to the outer surface of the threaded rod 9, providing a lateral movement power source for the movable seat 2 when the threaded rod 9 rotates, and precisely controlling the movement distance and speed of the movable seat 2 through the threaded engagement, a snap-fit ​​6 slidably connected to the inner surface of the movable seat 2, allowing the snap-fit ​​6 to move vertically along the inner surface of the movable seat 2, and a bolt 8 rotatably connected to the top of the inner surface of the snap-fit ​​6, the outer surface of the bolt 8 penetrating and threadedly connected to the top of the outer surface of the movable seat 2, the bolt 8 being used to adjust the snap-fit. The vertical position of component 6 within the movable base 2 allows for precise control of the engagement and disengagement of the locking component 6 and the locking block 7 via rotating bolt 8. A push plate 5 is slidably connected to the inner surface of the base 1, enabling the push plate 5 to move laterally along the inner surface of the base 1. The top of the outer surface of the push plate 5 is fixedly connected to the locking block 7, allowing the push plate 5 to move together with the locking block 7 as it moves laterally. The bottom of the outer surface of the locking component 6 engages with the outer surface of the locking block 7, allowing the push plate 5 to move together with the movable base 2 due to the engagement of the locking component 6 and the locking block 7. Multiple sets of locking blocks 7 are provided, and the engagement position of the push plate 5 and the movable base 2 can be adjusted according to actual needs to control the distance the movable base 2 moves the push plate 5.

[0033] Reference Figure 2 , Figure 4 The inner surface of the base 1 is provided with a cleaning component 10, which enables the debris concentrated by the push plate 5 to be discharged uniformly through the cleaning component 10. The cleaning component 10 includes a baffle gate 101. The top of the outer surface of the baffle gate 101 is hinged to the left side of the inner surface of the base 1, so that the baffle gate 101 can be flipped outward along the left side of the inner surface of the base 1. The bottom of the outer surface of the baffle gate 101 is fixedly connected to the bottom of the outer surface of the base 1 through a pin 102, so that the pin 102 can firmly fix the baffle gate 101 to the base 1 when it is closed, ensuring the sealing of the storage chamber 11 during normal operation. A handle 103 is fixedly connected to the outer surface of the baffle gate 101. The handle 103 makes it convenient for the operator to apply force when opening or closing the baffle gate 101, making the operation more convenient and labor-saving.

[0034] Reference Figures 2-4 A dust cover 4 is fixedly connected to the middle of the inner surface of the base 1. The dust cover 4 can prevent debris, dust and other impurities generated during the processing from splashing onto the surface of the threaded rod 9, thus protecting the threaded rod 9 and extending its service life. The outer surface of the dust cover 4 penetrates and slides through the inner surface of the movable seat 2, so that the normal sliding of the movable seat 2 on the base 1 is not affected, and the threaded rod 9 is effectively protected by the dust cover 4. A guide block 12 is fixedly connected to the outer surface of the push plate 5, so that when the push plate 5 moves laterally, it can drive the guide block 12 to move together. The outer surface of the guide block 12 slides through the inner surface of the base 1, ensuring that the guide block 12 can slide along the predetermined track of the inner surface of the base 1, thereby ensuring the stable movement of the push plate 5.

[0035] Reference Figures 2-4 The guide rod 13 is fixedly connected to the middle of the inner surface of the base 1, providing a fixed support for the guide rod 13. The inner surface of the movable seat 2 is slidably connected to the outer surface of the guide rod 13, ensuring the smooth sliding of the movable seat 2 on the guide rod 13 and improving the stability of the movable seat 2 when moving. A storage chamber 11 is provided on the left side of the inner surface of the base 1, which is used to collect the debris pushed by the push plate 5. A clamping plate 3 is fixedly connected to the top of the outer surface of the base 1, which is used to fix the shaft forging on the clamping device. An auxiliary component is fixedly connected to the top of the outer surface of the movable seat 2, which provides additional auxiliary functions for the processing of shaft forging, such as auxiliary support and positioning, further improving the accuracy and stability of processing.

[0036] Working principle: When it is necessary to uniformly process the processing debris, first move the moving seat 2 to the rightmost side of the base 1, then rotate the bolt 8 to make it drive the locking piece 6 to move vertically downward, so that the locking piece 6 engages with the locking block 7 on the push plate 5. Then start the threaded rod 9 to move the moving seat 2 to the left side of the base 1. Because the locking piece 6 is engaged with the locking block 7, the push plate 5 will move simultaneously when the moving seat 2 moves laterally. When the push plate 5 moves to the left, it will scrape the bottom of the inner surface of the base 1 and push the debris inside the base 1 into the storage chamber 11 on the left side of the base 1. Then reverse the threaded rod 9 to make the moving seat 2 drive the push plate 5 to the right to reset. Then reverse the bolt 8 to release the engagement between the locking piece 6 and the locking block 7 on the push plate 5.

[0037] When the storage chamber 11 is full, the locking door 101 is released by pulling out the pin 102, and then the handle 103 is pulled outward to open the locking door 101 and remove the debris from the storage chamber 11.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
