Description

Technical Field

[0001] This application relates to the field of machining technology, specifically to an auxiliary clamping device for machining blind holes. Background Technology

[0002] In the fields of mechanical manufacturing and precision machining, blind hole machining is a common but technically demanding process. A blind hole refers to a hole structure that is open on only one side and closed on the other. It is widely used in shafts, housings, and complex structural parts to meet assembly, positioning, weight reduction, or functional requirements. Because the tool cannot penetrate the workpiece during blind hole machining, higher demands are placed on the workpiece's clamping stability, positioning accuracy, and dynamic control during the machining process.

[0003] Traditional clamping devices commonly suffer from uneven clamping force, large positioning errors, and inconvenient adjustment in blind hole machining. They lack sufficient adaptability and flexibility, especially when dealing with workpieces of different sizes, shapes, or materials. Furthermore, conventional fixtures often fail to effectively position shaft-like or cylindrical workpieces, easily leading to workpiece displacement, rotation, or vibration during machining. This affects machining accuracy and surface quality, and may even cause tool damage or workpiece scrap. Summary of the Invention

[0004] The technical problem to be solved by this application is to overcome the existing defects and provide an auxiliary clamping device for machining blind holes, which can effectively solve the problems in the background art.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0020] Please see Figure 1-4 This application provides a technical solution: an auxiliary clamping device for processing blind holes, including a bottom support 2, wherein pad support seats 1 are provided around the bottom support 2 to provide support and stability for the overall structure.

[0021] On the upper surface of the bottom support frame 2, there is a vertically arranged support plate assembly 10. Side support plates 12 are slidably fitted between the support plate assemblies 10. Clamping seats 8 are also provided on both sides of the support plate assembly 10 to further clamp the workpiece and ensure the stability of the processing.

[0022] The side support plate 12 is provided with a support pad 9, which is used to support the workpiece to be processed. A movable clamping seat is installed on the upper surface of the support pad 9, and a fixed clamping seat is provided opposite to the movable clamping seat. The fixed clamping seat is installed at the other end of the side support plate 12 to form a clamping structure and achieve stable positioning of the workpiece.

[0023] Furthermore, the movable clamping seat includes an adjusting cylinder 5 and a clamping member 3. The output end of the adjusting cylinder 5 is provided with the clamping member 3, which is used to drive the clamping and releasing actions of the clamping member 3. The end of the clamping member 3 is provided with a V-shaped groove so as to better fit the workpiece with shaft-shaped or cylindrical features and improve the clamping stability.

[0024] The fixed clamping seat includes a pad 4 and an upper clamping seat 11. The pad 4 is used to support the workpiece. The upper clamping seat 11 is correspondingly arranged with the clamping member 3 in the movable clamping seat. Its end is also provided with a V-shaped groove, so as to achieve stable bidirectional clamping of the workpiece in the clamping state.

[0025] To achieve precise positioning and machining of workpiece holes, a shaft positioning sleeve 13 is also provided on the side support plate 12. The shaft positioning sleeve 13 includes a positioning sleeve and an arched guide sleeve, wherein the positioning sleeve is installed on the arched guide sleeve, and the arched guide sleeve can slide in the side wing grooves provided on both sides of the side support plate 12 to adjust the positioning position of the shaft.

[0026] The lower end of the shaft positioning sleeve 13 is provided with a lifting adjustment seat, which is movably installed in the guide groove on the bottom support 2. The guide groove is located between the support vertical plate assemblies 10 and is used to adjust the positioning height of the shaft. Specifically, the lifting adjustment seat includes a lifting cylinder 15 and a shaft sleeve 14. The output end of the lifting cylinder 15 is connected to a support plate, and the shaft sleeve 14 is provided on the support plate. The shaft sleeve 14 contains a strong magnetic material to attract or fix metal shafts and improve machining accuracy.

[0027] A hanger plate 6 is also connected to one side of the lifting cylinder 15. The hanger plate 6 is used to coordinate the displacement action. A displacement cylinder 7 is connected to one side of the hanger plate 6. Thus, the horizontal displacement of the entire shaft sleeve 14 can be achieved by driving the displacement cylinder 7. This is used to adjust the position of the shaft when facing a workpiece of a certain diameter, thereby achieving the centering of the workpiece and improving the adjustability of the clamping and processing position.

[0028] A side plate frame 16 is installed at the upper end of the shaft positioning sleeve 13. A positioning seat 17 is hinged to its vertical surface. The positioning seat 17 is provided with a sliding groove. A punching component 18 is slidably installed in the sliding groove for performing blind hole machining. Through the sliding structure of the sliding groove and the hinged cooperation with the positioning seat 17, the adjustable angle and sliding stroke of the punching component 18 can be realized, improving the flexibility and adaptability of blind hole machining.

[0029] In use: Place the workpiece to be processed on the shaft sleeve 14, ensuring its axial direction or the part requiring drilling is positioned between the moving clamp and the fixed clamp. Adjust the position of the side support plate 12 so that it slides to a suitable position between the supporting vertical plate group 10. If the workpiece is made of metal, the strong magnetic material inside the shaft sleeve 14 can be used to assist in adsorption and positioning of the workpiece, improving overall clamping stability and preventing micro-movements from affecting processing quality. Adjust the height of the workpiece by adjusting the lifting adjustment seat. At this time, activate the adjusting cylinder 5 to push the clamping part 3 at its end to extend, thereby driving the clamping part 3 to move forward and clamp the workpiece together with the upper clamp 11 in the fixed clamp. Since both the clamping part 3 and the upper clamp 11 have V-shaped grooves at their ends, they stably fit cylindrical or irregularly shaped shaft workpieces, preventing them from rotating or sliding during processing and ensuring processing accuracy. If the diameter of the shaft is insufficient to achieve hole alignment processing using only the hinged positioning seat 17 and its sliding groove, the position of the shaft positioning sleeve 13 can be adjusted. The arched guide sleeve can slide within the side wing groove of the side support plate 12 to achieve fine adjustment of the shaft to be processed in the horizontal direction; adjust the angle of the positioning seat 17 located on the side plate frame 16 so that its vertical face is aligned with the target area of ​​the workpiece. At this time, the drilling part 18 is activated to drill holes in the workpiece. After processing is completed, release the adjusting cylinder 5 to reset the moving clamp, loosen the workpiece clamping state, remove the processed workpiece, and proceed to the next round of processing or subsequent processing.

[0030] This application utilizes the combination of clamping and positioning modules to provide stable positioning and adjustment support for the workpiece during blind hole machining, effectively improving machining quality and efficiency. It is suitable for industrial scenarios requiring high-precision blind hole machining.

[0031] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
