Description

Technical Field

[0001] This utility model belongs to the field of parts processing technology, and in particular relates to a support device for machining shaft-type parts on CNC lathes. Background Technology

[0002] Shafts are an important component of electrical industry products, used for fixing and supporting large electrical equipment. The machining of shafts is typically done using CNC lathes, which are automated machine tools equipped with a program control system. This control system can logically process and decode programs with control codes or other symbolic instructions, thereby enabling the machine tool to move and machine parts. CNC lathes play a crucial role in our machinery manufacturing industry.

[0003] Currently, CNC lathes do not have material support devices at the tail end of the machine tool. As a result, after long materials are clamped, the tail end of the material naturally falls due to gravity, and the entire material is in an inclined state. During operation, the friction between the material and the machine tool will generate a lot of friction and noise, or the entire material may come out and cause injury, affecting normal production and processing. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a support device for machining shaft-type parts on CNC lathes, which effectively prevents the material from tilting due to gravity during machining. This not only reduces unnecessary friction between the material and the machine tool and lowers noise pollution, but also avoids safety accidents that may be caused by the material shaking or falling out, thus improving the stability and safety of the overall machining process.

[0005] This utility model is implemented as follows: This application provides a support device for machining shaft-type parts in a CNC lathe, including a support column, a support base provided at the upper end of the support column, and an installation clamp provided on the mounting platform of the support base through a shock-absorbing component. A raw material sleeve for shaft-type parts to pass through is clamped in the installation clamp.

[0006] Furthermore, the damping component includes a fixing bolt, the end of which passes through the mounting clamp and the support seat sequentially and is fixed by a nut. A first elastic element is sleeved on the bolt located between the upper end face of the support seat and the lower end face of the mounting clamp, and a second elastic element is sleeved on the bolt located between the upper end face of the mounting clamp and the bolt head. Tightening the fixing bolt with the nut can achieve pre-tightening and fixing of the mounting clamp, and at the same time, it can adjust the installation position of the mounting clamp to ensure that the shaft parts inside the raw material sleeve remain parallel to the ground and located at the center of the feed port on the CNC lathe. Both the first and second elastic elements play a role in buffering and shock absorption. During processing, the vibration and impact force of the machine tool can be effectively absorbed by these elastic elements, thereby protecting the mounting clamp, the support seat, and the shaft parts from damage.

[0007] Furthermore, the mounting fixture includes a locking part and a mounting part. The mounting part is located on both sides of the locking part. The locking part is an annular structure with an opening at the top, and its inner diameter is adapted to the outer diameter of the raw material sleeve. The shock-absorbing component is disposed on the mounting part. The locking part is designed as an annular structure with its inner diameter adapted to the outer diameter of the raw material sleeve. This design ensures that the raw material sleeve can be accurately clamped in the mounting fixture. This precise clamping method not only improves the stability of processing but also helps to reduce errors during processing.

[0008] Furthermore, a fastening bolt is provided on the engaging part, the end of which penetrates the engaging part and abuts against the outer wall of the raw material sleeve. The fastening bolt acts directly on the outer wall of the raw material sleeve, and by adjusting the tightness of the bolt, a tight clamping of the raw material sleeve can be achieved. This clamping method is more direct and effective than traditional clamping methods relying on friction or elastic elements, providing greater clamping force, ensuring the stability of the raw material sleeve during processing, and ensuring the positional accuracy of the raw material sleeve in the mounting fixture, thereby reducing processing errors caused by the wobbling or displacement of the raw material sleeve. This high-precision clamping method helps improve the processing accuracy and finished product quality of shaft parts.

[0009] Furthermore, two mounting clamps are provided, each positioned at one end of the raw material sleeve along its axial direction. These two clamps, located at opposite ends of the raw material sleeve, provide more balanced and stable support. This design effectively prevents bending or shaking of the raw material sleeve during processing, improving processing stability; it also ensures the straightness and coaxiality of the raw material sleeve during processing, thus meeting the requirements of high-precision machining.

[0010] Furthermore, a protective cover is provided on the support base, and the side plate of the protective cover is connected to the side wall of the support base. The protective cover and the support base form a receiving cavity, in which the mounting fixture and the raw material sleeve are placed. The protective cover provides a relatively enclosed working environment for the mounting fixture and the raw material sleeve, which can effectively prevent splashes, chips, or other debris generated during processing from injuring operators, improving work safety, reducing equipment damage and performance degradation caused by contamination, and extending the service life of the equipment.

[0011] Furthermore, the outer layer of the raw material casing is a steel pipe, and the inner layer is nested with a nylon tube. By nesting the nylon tube inside the steel pipe, the high strength of the steel pipe can be fully utilized, improving the overall strength and load-bearing capacity of the raw material casing. The steel pipe can withstand greater external pressure and impact, protecting the inner nylon tube from damage. This combined inner and outer design allows the raw material casing to maintain structural integrity and stability even under heavy pressure. The nylon tube is renowned for its excellent wear resistance; nesting it inside the steel pipe effectively extends the service life of the entire raw material casing. This wear resistance is particularly important in applications requiring frequent movement or subject to friction, significantly reducing downtime and maintenance costs due to wear. Furthermore, the nylon tube possesses damping properties, absorbing and dispersing vibration and noise. Therefore, in applications requiring reduced noise and vibration, the inner nylon tube of the raw material casing can provide effective assistance, improving the working environment and conditions.

[0012] The advantages and technical effects of this utility model are as follows: By adopting the above-mentioned technical solution, the straightness and stability of shaft parts during processing are ensured, and processing errors caused by material tilting are reduced, thereby improving the processing accuracy and finished product quality of shaft parts. The support columns and support seats provide additional support points for long, strip-shaped shaft materials, effectively preventing tilting caused by the material naturally falling under gravity during processing. This not only reduces unnecessary friction between the material and the machine tool and lowers noise pollution, but also avoids safety accidents that may be caused by material shaking or detachment, improving the overall stability and safety of the processing.

[0019] like Figures 1 to 3 As shown, this application provides a support device for machining shaft-type parts in a CNC lathe, including a support column 1, a support base 2 at the upper end of the support column 1, and a mounting clamp 4 provided on the mounting table of the support base 2 through a shock-absorbing component 3. A raw material sleeve 5 for shaft-type parts 6 to pass through is clamped in the mounting clamp 4.

[0020] Furthermore, the damping component 3 includes a fixing bolt 3-1. The end of the bolt 3-1 passes through the mounting clamp 4 and the support seat 2 in sequence and is fixed by a nut. A first elastic element 3-2 is sleeved on the bolt between the upper end face of the support seat 2 and the lower end face of the mounting clamp 4, and a second elastic element 3-3 is sleeved on the bolt between the upper end face of the mounting clamp 4 and the bolt head. Specifically, both the first elastic element 3-2 and the second elastic element 3-3 are springs. Tightening the fixing bolt 3-1 with the nut can achieve pre-tightening and fixing of the mounting clamp 4, and at the same time, it can adjust the installation position of the mounting clamp 4 to ensure that the shaft parts 6 inside the raw material sleeve 5 remain parallel to the ground and located at the center of the feed port on the CNC lathe. The first elastic element 3-2 and the second elastic element 3-3 both play a role in buffering and shock absorption. During the processing, the vibration and impact force of the machine tool can be effectively absorbed by these elastic elements, thereby protecting the mounting clamp 4, the support seat 2, and the shaft parts 6 from damage.

[0021] Furthermore, the mounting fixture 4 includes a locking part 4-1 and a mounting part 4-2. The mounting part 4-2 is disposed on both sides of the locking part 4-1. The locking part 4-1 is an annular structure with an opening at the upper end, and its inner diameter is adapted to the outer diameter of the raw material sleeve 5. The shock-absorbing component 3 is disposed on the mounting part 4-2. The locking part 4-1 is designed as an annular structure, and its inner diameter is adapted to the outer diameter of the raw material sleeve 5. This design ensures that the raw material sleeve 5 can be accurately clamped in the mounting fixture 4. This precise clamping method not only improves the stability of processing but also helps to reduce errors during processing.

[0022] Furthermore, a fastening bolt 7 is provided on the engaging part 4-1, with the end of the fastening bolt 7 penetrating the engaging part 4-1 and abutting against the outer wall of the raw material sleeve 5. The fastening bolt 7 can directly act on the outer wall of the raw material sleeve 5, and by adjusting the tightness of the bolt, a tight clamping of the raw material sleeve 5 can be achieved. This clamping method is more direct and effective than traditional clamping methods that rely on friction or elastic elements, providing greater clamping force, ensuring the stability of the raw material sleeve 5 during processing, and ensuring the positional accuracy of the raw material sleeve 5 in the mounting fixture 4, thereby reducing processing errors caused by the shaking or displacement of the raw material sleeve 5. This high-precision clamping method helps to improve the processing accuracy and finished product quality of the shaft parts 6.

[0023] Furthermore, two mounting clamps 4 are provided, each positioned at one end of the raw material sleeve 5 along its axial direction. The two mounting clamps 4, located at opposite ends of the raw material sleeve 5, provide more balanced and stable support. This design effectively prevents bending or shaking of the raw material sleeve 5 during processing, improving processing stability; it also ensures the straightness and coaxiality of the raw material sleeve 5 during processing, thus meeting the requirements of high-precision machining.

[0024] Furthermore, a protective cover 8 is provided on the support base 2. The side plate of the protective cover 8 is connected to the side wall of the support base 2. The protective cover 8 and the support base 2 form a receiving cavity, in which the mounting clamp 4 and the raw material sleeve 5 are placed. The protective cover 8 provides a relatively enclosed working environment for the mounting clamp 4 and the raw material sleeve 5, which can effectively prevent splashes, chips or other debris generated during processing from injuring operators, improve work safety, reduce equipment damage and performance degradation caused by contamination, and extend the service life of the equipment.

[0025] Furthermore, the outer layer of the raw material sleeve 5 is a steel pipe, and the inner layer of the raw material sleeve 5 is nested with a nylon tube. By nesting the nylon tube inside the steel pipe, the high strength characteristics of the steel pipe can be fully utilized, improving the overall strength and load-bearing capacity of the raw material sleeve 5. The steel pipe can withstand greater external pressure and impact, protecting the inner nylon tube from damage. This combined inner and outer design allows the raw material sleeve 5 to maintain structural integrity and stability even under heavy pressure. The nylon tube is known for its excellent wear resistance; nesting it inside the steel pipe effectively extends the service life of the entire raw material sleeve 5. This wear resistance is particularly important in applications requiring frequent movement or subject to friction, significantly reducing downtime and maintenance costs caused by wear. Furthermore, the nylon tube has certain damping properties, absorbing and dispersing vibration and noise. Therefore, in applications requiring reduced noise and vibration, the inner nylon tube of the raw material sleeve 5 can provide effective assistance, improving the working environment and conditions.

[0026] By adopting the above technical solution, the straightness and stability of the shaft part 6 during processing are ensured, and processing errors caused by material tilting are reduced, thereby improving the processing accuracy and finished product quality of the shaft part 6. The support column 1 and support base 2 provide additional support points for the long, strip-shaped shaft material, effectively preventing tilting caused by gravity during processing. This not only reduces unnecessary friction between the material and the machine tool and lowers noise pollution, but also avoids potential safety accidents caused by material shaking or detachment, improving the overall stability and safety of the processing.
