Abstract
Description
Technical Field
[0001] This utility model belongs to the field of spline shaft processing technology, specifically relating to a high-power transmission spline shaft processing fixture. Background Technology
[0002] Splined shafts are a type of mechanical transmission, similar in function to parallel keys, semi-circular keys, and wedge keys, all of which transmit mechanical torque. They have longitudinal keyways on their outer surface, and rotating components fitted onto the shaft also have corresponding keyways to maintain synchronous rotation with the shaft. Modern splined shaft machining requires multiple processes, including turning. Due to the special grooves of the splined shaft, specific machine tools are used for processing. These machine tools mainly consist of a clamping base, a lead screw drive, and a turning tool. The clamping base fixes the splined shaft to be machined, and then the lead screw drive moves the clamped splined shaft to the side of the rotating turning tool for machining.
[0003] When machine tools are in use, due to the direct contact between the turning tool and the spline shaft, a certain amount of metal chips are generated during the machining process. These chips are splashed into the surrounding area, which can affect the operators controlling the operation of the machine tool and reduce the overall working quality of the machine tool. Utility Model Content
[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0005] To address the problems mentioned in the background section, the present invention adopts the following technical solution.
[0006] A high-power transmission spline shaft machining fixture includes a base, a machining part, and a clamping base. The clamping base is mounted on the base to clamp the spline shaft to be machined. The clamping base moves on the base to push the spline shaft to be machined to move. The machining part is mounted on the side of the base. The machining part performs turning processing on the spline shaft to be machined. The machining part is equipped with a protective mechanism to shield the debris splashed during machining.
[0007] As a preferred embodiment of the present invention, the protective mechanism includes a shielding component and a cleaning component. The shielding component is installed on the side of the workpiece to shield the splashed debris, and the cleaning component is installed inside the shielding component to clean the components in the shielding component.
[0008] As a preferred technical solution of this utility model, the shielding component includes a blocking member, a socket frame and a lower baffle. The socket frame is installed on the side of the workpiece, and the blocking member is installed at the end of the socket frame. The lower baffle is rotatably installed on the side of the blocking member. A torsion spring is installed at the connection between the lower baffle and the blocking member. When the lower baffle is rotated, the torsion spring enters the storage state. A handle for rotating the angle of the lower baffle is installed on the side wall of the lower baffle.
[0009] As a preferred technical solution of this utility model, the blocking member includes an upper baffle, which is installed at the end of the socket. The upper baffle has a semi-circular structure and blocks the debris splashed during the processing of the spline shaft.
[0010] As a preferred technical solution of this utility model, the blocking member includes a connecting plate and a side guard plate. The connecting plate is installed at the end of the socket bracket and blocks the debris splashed from the side of the spline shaft. The side guard plate is installed on the side of the connecting plate and intersects the connecting plate perpendicularly. The side guard plate blocks the debris in the slotting direction of the spline shaft.
[0011] As a preferred technical solution of this utility model, the cleaning component includes a cleaning scraper and a cleaning brush. The cleaning scraper is installed on the side wall of the blocking member to clean the oil stains and debris remaining on the surface of the lower baffle, and the cleaning brush is symmetrically installed on the side wall of the lower baffle to clean the impurities on the surface of the blocking member.
[0012] As a preferred technical solution of this utility model, the machining part includes a control end, a turning tool and a support base. The control end is installed on the side of the base, and the support base is installed on the side of the control end. A turning tool for turning the spline shaft is installed between the end of the support base and the control end.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, a protective mechanism is provided. After the clamping base clamps the spline shaft, the movement of the lead screw in the base drives the spline shaft to move towards the turning tool. At this time, the combination of the blocking component and the lower baffle blocks the side of the upper spline shaft that is close to the operator's operation of the clamping base, preventing debris and oil from splashing onto the operator. Furthermore, when a large amount of debris and oil adheres to the lower baffle and the blocking component, the angle of the lower baffle is rotated to achieve synchronous cleaning of the lower baffle and the blocking component, ensuring the safety and stability of the machining fixture during overall use.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.
[0024] Example 1 like Figure 1As shown, this is a schematic diagram of the high-power transmission spline shaft machining fixture in this embodiment. The machining fixture can stably lock the position of the spline shaft and shield and protect the splashed metal chips during the turning process of the spline shaft, preventing the chips from splashing onto the operator. The machining fixture includes a base 1, a machining part 2, and a clamping base 3. The clamping base 3 for clamping and fixing the spline shaft is installed on the base 1. The machining part 2 is installed on the side of the base 1. The machining part 2 itself performs turning processing on the spline shaft, and a protective mechanism 4 for shielding the detected metal chips is installed on the machining part 2.
[0025] As attached Figure 2 As shown, this is a schematic diagram of the structure of the base 1 in this embodiment. The base 1 includes a lower base plate 11, a lead screw 12, a moving end 13, and a rotating frame 14. The lower base plate 11 is a support bracket for the entire machining fixture. A moving groove is provided on the lower base plate 11. The lead screw 12 is rotatably installed in the moving groove. The moving end 13 is threadedly installed on the outside of the lead screw 12. The top end of the moving end 13 is connected to the bottom end of the clamping base 3. The rotation of the lead screw 12 drives the moving end 13 to drive the rotating frame 14 to move horizontally, so as to move the spline shaft installed on the clamping base 3 and assist the spline shaft to undergo turning. The rotating frame 14 is provided at the end of the lower base plate 11. The rotating frame 14 is connected to the end of the lead screw 12. The operator drives the lead screw 12 to rotate inside the moving groove by rotating the rotating frame 14.
[0026] As attached Figure 3 As shown, this is a schematic diagram of the structure of the machining part 2 in this embodiment. The machining part 2 includes a control end 21, a turning tool 22, and a support base 23. The control end 21 is installed on the side of the lower base plate 11. The support base 23 is installed on the side wall of the control end 21. The turning tool 22 for turning the spline shaft is installed on the side wall of the control end 21 and below the support base 23. The end of the turning tool 22 is connected to the support base 23. A drive motor for driving the turning tool 22 to rotate is installed inside the control end 21. When the rotating frame 14 pushes the clamping base 3 to move, the spline shaft installed on the clamping base 3 moves to the side of the turning tool 22, which facilitates the turning tool 22 to process the spline shaft. A control panel is installed on the surface of the control end 21, and the control panel controls the operation of the drive motor.
[0027] As attached Figure 4 and Figure 5As shown, this is a schematic diagram of the protective mechanism 4 in this embodiment. The protective mechanism 4 includes a blocking member 41, a connecting frame 42, and a lower baffle 43. The connecting frame 42 is installed on the support base 23. The blocking member 41 is installed at the end of the connecting frame 42. The lower baffle 43 is rotatably installed on the side of the blocking member 41. A torsion spring 45 is installed inside the lower baffle 43. The other end of the torsion spring 45 is connected to the inner wall of the blocking member 41. When the lower baffle 43 rotates, the torsion spring 45 enters the storage state. A handle 44 is installed on the side of the lower baffle 43 to assist the lower baffle 43 in rotating and limit the maximum rotation angle of the lower baffle 43. When the lower baffle 43 is in the initial position, it forms a complete shield with the blocking member 41. A cleaning scraper 46 is installed on the side wall of the blocking member 41 to clean the impurities remaining on the surface of the lower baffle 43. A cleaning brush 47 is symmetrically installed on the side wall of the lower baffle 43 near the blocking member 41 to clean the surface of the blocking member 41.
[0028] It is worth noting that the blocking member 41 and the lower baffle 43 in this embodiment have the same structure, both being semi-circular structures. In this embodiment, the blocking member 41, the sleeve bracket 42, the lower baffle 43, the handle 44, and the torsion spring 45 form a shielding assembly, while the cleaning scraper 46 and the cleaning brush 47 form a cleaning assembly.
[0029] As attached Figure 5 As shown, it is a structural schematic diagram of the blocking member 41 in this embodiment. The blocking member 41 includes an upper baffle 411. The upper baffle 411 is installed at the end of the socket 42. The upper baffle 411 shields the debris generated during the processing of the spline shaft and prevents the debris from splashing onto the operator.
[0030] Example 2 As attached Figure 6 As shown, it is a structural schematic diagram of the blocking member 41 in this embodiment. The difference between this embodiment and embodiment 1 is that the blocking member 41 in this embodiment includes a connecting plate 412 and a side guard plate 413. The connecting plate 412 is installed at the end of the socket 42, and the side guard plate 413 is installed on the side of the connecting plate 412. The side guard plate 413 blocks the debris splashed during the processing of the spline shaft from another angle, preventing the debris from splashing to the outside as the turning tool 22 rotates.
[0031] The above description provides a more detailed explanation of the present invention in conjunction with specific embodiments. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present invention.
