Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a thin-walled piece numerical control processing support device. Background Art

[0002] Thin-walled structural parts have the advantages of compact structure, high strength and light weight. In recent years, they have been widely used in the aerospace and aviation fields. However, they have poor rigidity and are easily deformed by the cutting force of the tool during processing, which seriously affects the processing accuracy and performance of the parts. Aerospace and aviation products have high quality requirements. Usually, special tooling is required to ensure the processing requirements. However, the production cost of special tooling is high and the production cycle is long, which cannot meet the rapid development of the aerospace industry. Moreover, a special tooling is usually only suitable for one product and has a narrow application range. Especially in the case of a short sample delivery cycle, since it is impossible to make special tooling, manufacturers can only choose universal support rods for support. However, the existing universal support rods have poor support effects, are not easy to adjust, and have limited support positions, resulting in low versatility. Therefore, in view of the problem that thin-walled parts have poor rigidity and are easy to deform, effective support is designed to increase their rigidity, which helps to improve the processing quality and efficiency of parts and has a relatively broad application prospect. After long-term research by the inventor, a thin-walled part CNC machining support device was invented. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a thin-walled part numerical control machining support device.

[0004] The purpose of the utility model is achieved through the following technical scheme: a thin-walled part CNC machining support device, including a base, the base is slidably installed on the machine tool base, a support frame is arranged on the base, a support sleeve is installed on the support frame, mounting holes b and mounting holes c are respectively opened on both sides of the support sleeve, and the mounting holes b and mounting holes c are both used to connect the support rod, and a supporting part is arranged at the end of the support rod, and the supporting part is used to support the wall surface of the thin-walled part.

[0005] Preferably, a threaded section a is provided on the surface of the support frame, the lower end of the support frame is connected and fixed to the base, and a threaded section b corresponding to the threaded section a is provided on the inner wall of the mounting hole a.

[0006] Preferably, a locking nut is provided on the support frame, and the upper and lower ends of the support sleeve are locked by the locking nut.

[0007] Preferably, the thread lead angle of the support frame is smaller than the friction angle.

[0008] Preferably, the support portion is connected to the support rod by means of screws, and the end surface of the support portion is arc-shaped.

[0009] Preferably, a wedge block is further provided between the support portion and the support rod.

[0010] Preferably, the cross section of the wedge block is triangular.

[0011] Preferably, a plurality of slide grooves are provided on the machine tool base, the base is located on the surface of the slide groove, fixed blocks are provided at both ends of the base, a screw is provided on the fixed block, and the nut of the screw is located at the bottom of the slide groove, and the screw is locked by a locking nut b.

[0012] Preferably, the slide grooves are provided at equal intervals on the machine tool base.

[0013] Preferably, a mounting hole a is provided on the support sleeve, and the support frame is installed in the mounting hole a.

[0014] The utility model has the following advantages:

[0015] 1. The utility model adjusts the position of the base on the machine tool base so that the support part can support thin-walled parts of different diameters. At the same time, by selectively installing the support rod in the mounting hole b or the mounting hole c, the outside or inside of the thin-walled part can be supported, and the support sleeve can be adjusted up and down on the support frame to support thin-walled parts of different heights, thereby improving versatility.

[0016] 2. When the thin-walled workpiece is a straight tube, the staff will choose to install the support rod in the mounting hole b or the mounting hole c to provide horizontal support for the thin-walled workpiece. When supporting horizontally, the supporting force is mainly along the axis direction of the support rod. There is no bending moment on the support rod, and the force is simple, thereby enhancing the rigidity and stability, and effectively ensuring the support reliability.

[0017] 3. When the thin-walled part is a small-taper workpiece, the staff will set the wedge block between the support part and the support rod to make the inclined surface of the support part fit with the thin-walled part, and then install the support rod in the mounting hole b or the mounting hole c to horizontally support the thin-walled part, thereby ensuring the supporting effect.

[0018] 4. When the thin-walled part is a large-taper workpiece, the staff will set the wedge block between the support part and the support rod to make the inclined surface of the support part fit with the thin-walled part, and install the support sleeve on the top of the support frame through the mounting hole b thread, and then install the support rod in the mounting hole c thread to vertically support the thin-walled part. When vertically supporting, the support rod and the support frame are on the same vertical line, and the force is pressure, which ensures the support rigidity.

[0019] 5. The utility model makes the threaded section a on the surface of the support frame threadedly connected with the threaded section b on the inner wall of the mounting hole a, so that the support position of the thin-walled part can be adjusted according to its height, thereby realizing effective support at different heights.

[0020] 6. The thread lead angle of the support frame of the utility model is smaller than the friction angle, thereby achieving self-locking, thereby ensuring the stability and reliability of the support device.

[0021] 7. By providing locking nuts at the upper and lower ends of the support sleeve, the stability of the support sleeve can be further improved to prevent the support sleeve from moving relative to the support frame during the support process.

[0022] 8. The utility model sets the end surface of the support part into an arc shape, which can increase the contact area between the support part and the thin-walled part and reduce the contact stress.

[0023] 9. When the thin-walled workpiece is a small-taper workpiece or a large-taper workpiece, the staff can select the corresponding wedge block according to the thin-walled workpieces with different tapers and install it between the support part and the support rod to tilt the support part to ensure a better fit between the support part and the tapered surface of the thin-walled workpiece.

[0024] 10. The utility model provides slide grooves at equal intervals on the machine tool base, and when the base moves, the slide grooves are used to limit the base, so that the support part can evenly support the thin-walled parts to avoid deformation of the workpiece.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In this embodiment, if Figure 1 and Figure 4 As shown, a thin-walled workpiece numerical control machining support device includes a base 3, the base 3 is slidably mounted on a machine tool base 1, a support frame 7 is arranged on the base 3, a support sleeve 8 is installed on the support frame 7, and mounting holes b12 and mounting holes c16 are respectively opened on both sides of the support sleeve 8, and the mounting holes b12 and mounting holes c16 are both used to connect a support rod 10, and a support portion 11 is arranged at the end of the support rod 10, and the support portion 11 is used to support the wall surface of the thin-walled workpiece. Preferably, a mounting hole a15 is opened on the support sleeve 8, and the support frame 7 is installed in the mounting hole a15. By adjusting the position of the base 3 on the machine tool base 1, the support portion 11 can support thin-walled workpieces of different diameters, and by selectively installing the support rod 10 in the mounting hole b12 or the mounting hole c16, the outside or inside of the thin-walled workpiece can be supported, and the support sleeve 8 can be adjusted up and down on the support frame 7 to support thin-walled workpieces of different heights, thereby improving versatility. In this embodiment, the thread specifications of the mounting holes a15, b12 and c16 are the same, and the central axes of the mounting holes b12 and c16 are perpendicular to the central axis of the mounting hole a15, thereby facilitating horizontal and vertical support.

[0044] Furthermore, a thread segment a is provided on the surface of the support frame 7, the lower end of the support frame 7 is connected and fixed to the base 3, and a thread segment b corresponding to the thread segment a is provided on the inner wall of the mounting hole a15. Preferably, the thread lead angle of the support frame 7 is smaller than the friction angle. Specifically, the support frame 7 and the support sleeve 8 are connected by threaded matching, so that the support sleeve 8 can adjust its support position according to the height of the thin-walled part to achieve effective support at different heights; at the same time, the main purpose of its thread lead angle being smaller than the friction angle is to achieve self-locking, thereby ensuring the stability and reliability of the support device. In this embodiment, a locking nut 9 is provided on the support frame 7, and the upper and lower ends of the support sleeve 8 are locked by the locking nut 9. Specifically, by providing locking nuts 9 at the upper and lower ends of the support sleeve 8, the stability of the support sleeve 8 can be further improved, and the relative movement of the support sleeve 8 on the support frame 7 during the support process can be avoided.

[0045] Furthermore, the support portion 11 is connected to the support rod 10 by means of a screw 14, and the end face of the support portion 11 is arc-shaped. Preferably, the support portion 11 is made of nylon. Specifically, the main function of the arc-shaped end of the support portion 11 is to make the contact surface between the support portion 11 and the thin-walled part a curved surface, thereby effectively increasing the contact area between the support portion 11 and the thin-walled part and reducing the contact stress. At the same time, the support portion 11 is made of non-metallic material nylon, which is also to ensure that the support portion 11 effectively supports the thin-walled part while reducing the contact stress and avoiding deformation of the thin-walled part.

[0046] In this embodiment, if Figure 2 and Figure 3 As shown, a wedge block 13 is also provided between the support portion 11 and the support rod 10. Specifically, for small-taper workpieces and large-taper workpieces, the staff installs the wedge block 13 between the support portion 11 and the support rod 10, so that the support portion 11 is tilted to ensure that the support portion 11 and the tapered surface of the thin-walled workpiece can fit better, thereby ensuring the supporting effect. That is to say, the wedge block 13 is only needed when the thin-walled workpiece is a small-taper workpiece or a large-taper workpiece, and is not needed when it is a straight-tube workpiece. Further, as Fig.11 As shown, the cross section of the wedge block 13 is a triangle. Specifically, for thin-walled parts with different tapers, the angle of the wedge block 13 will also be different, that is, the wedge angle ( Fig.11 A) in the figure will change, and the staff can select the corresponding wedge block 13 according to the actual situation to tilt the support part 11 so that the support part 11 can better fit the tapered surface of the thin-walled part.

[0047] In this embodiment, a plurality of chutes 2 are provided on the machine tool base 1, and the base 3 is located on the surface of the chutes 2. Fixed blocks 4 are provided at both ends of the base 3, and screws 6 are provided on the fixed blocks 4, and the nuts of the screws 6 are located at the bottom of the chutes 2, and the screws 6 are locked by locking nuts b5. Specifically, the bottom of the chutes 2 has a limiting groove, the width of the limiting groove is greater than the width of the upper part of the chutes 2, and the nuts of the screws 6 are located in the limiting groove, and the purpose is to limit and fix the support device. When the support device needs to be moved, the staff loosens the locking nuts b5 on the fixed blocks 4 at both ends of the base 3. Since the nuts of the screws 6 are located in the limiting groove, the base 3 cannot move up and down, and can only move radially along the chutes 2. When the staff moves the base 3 to a suitable position, the locking nuts b5 are tightened, thereby fixing the position of the base 3 and ensuring the supporting effect of the support part 11 on the thin-walled parts. Further, the chutes 2 are provided at equal intervals on the machine tool base 1. Specifically, eight slide grooves 2 are provided on the machine tool base 1, and each slide groove 2 is provided with a supporting device, so that when the staff moves the base 3 to a suitable position, the supporting part 11 can evenly support the thin-walled part to avoid deformation of the workpiece.

[0048] The working process of the utility model is as follows:

[0049] 1. When the thin-walled workpiece is a straight cylindrical workpiece and internal support is required for the straight cylindrical workpiece, such as Figure 5 As shown, the staff first places the thin-walled part on the machine tool base 1, and then threadedly installs the support rod 10 in the mounting hole c16. After the staff completes the installation of the support rod 10, according to the actual height of the thin-walled part, by adjusting the position of the support sleeve 8 on the support frame 7, the support part 11 can support the thin-walled part, and then loosens the locking nuts b5 on the fixing blocks 4 at both ends of the base 3. Under the restriction of the slide groove 2, the staff moves the base 3 along the slide groove 2. When the base 3 is moved to a suitable position, that is, the support part 11 fits with the surface of the thin-walled part, the staff tightens the locking nuts b5 to fix the position of the base 3, so that the support part 11 horizontally supports the thin-walled part. When performing horizontal support, the supporting force of the support part 11 is mainly along the axial direction of the support rod 10, so that there is no bending moment on the support rod 10, and its force is simple, thereby enhancing the rigidity and stability, and effectively ensuring the support reliability.

[0050] 2. When the thin-walled workpiece is a straight cylindrical workpiece and external support is required for the straight cylindrical workpiece, such as Figure 6 As shown, the staff first places the thin-walled part on the machine tool base 1, and then threadably installs the support rod 10 in the mounting hole b12. After the staff completes the installation of the support rod 10, according to the actual height of the thin-walled part, by adjusting the position of the support sleeve 8 on the support frame 7, the support part 11 can support the thin-walled part, and then loosens the locking nuts b5 on the fixing blocks 4 at both ends of the base 3. Under the restriction of the slide groove 2, the staff moves the base 3 along the slide groove 2. When the base 3 is moved to a suitable position, that is, the support part 11 fits with the surface of the thin-walled part, the staff tightens the locking nuts b5 to fix the position of the base 3, so that the support part 11 horizontally supports the thin-walled part. When performing horizontal support, the supporting force of the support part 11 is mainly along the axial direction of the support rod 10, so that there is no bending moment on the support rod 10, and its force is simple, thereby enhancing the rigidity and stability, and effectively ensuring the support reliability.

[0051] 3. When the thin-walled workpiece is a small-taper workpiece and internal support is required for the small-taper workpiece, such as Figure 7As shown, the staff first places the thin-walled workpiece on the machine tool base 1, and then selects the corresponding wedge block 13 according to the taper size of the thin-walled workpiece, so that the inclined surface of the support part 11 fits with the thin-walled workpiece, and the staff fixes the wedge block 13 between the support part 11 and the support rod 10 by screws 14. After the fixing is completed, the support rod 10 is threadedly installed in the mounting hole c16. After the staff installs the support rod 10, according to the actual height of the thin-walled workpiece, the position of the support sleeve 8 on the support frame 7 is adjusted, and the locking nuts b5 on the fixing blocks 4 at both ends of the base 3 are loosened. Under the restriction of the slide groove 2, the staff moves the base 3 along the slide groove 2. When the base 3 is moved to the appropriate position, that is, the inclined surface of the support part 11 fits with the thin-walled workpiece, which is convenient for supporting the thin-walled workpiece. The staff then tightens the locking nut b5 to fix the position of the base 3, so that the support part 11 horizontally supports the thin-walled workpiece, thereby ensuring the supporting effect.

[0052] 4. When the thin-walled workpiece is a small-taper workpiece and external support is required for the small-taper workpiece, such as Figure 8 As shown, the staff first places the thin-walled part on the machine tool base 1, and then selects the corresponding wedge block 13 according to the taper size of the thin-walled part, so that the inclined surface of the support part 11 fits with the thin-walled part. The staff fixes the wedge block 13 between the support part 11 and the support rod 10 by screws 14. After the fixing is completed, the support rod 10 is threadedly installed in the mounting hole b12. After the staff installs the support rod 10, according to the actual height of the thin-walled part, the position of the support sleeve 8 on the support frame 7 is adjusted, and the locking nuts b5 on the fixing blocks 4 at both ends of the base 3 are loosened. Under the restriction of the slide slot 2, the staff moves the base 3 along the slide slot 2. When the base 3 is moved to the appropriate position, the inclined surface of the support part 11 fits with the thin-walled part, which is convenient for supporting the thin-walled part. The staff then tightens the locking nut b5 to fix the position of the base 3, so that the support part 11 horizontally supports the thin-walled part, thereby ensuring the supporting effect.

[0053] 5. When the thin-walled workpiece is a large-taper workpiece and internal support is required for the large-taper workpiece, such as Fig. 9As shown, the staff first places the thin-walled part on the machine tool base 1, and then selects the corresponding wedge block 13 according to the taper size of the thin-walled part, so that the inclined surface of the support part 11 fits the thin-walled part. The staff fixes the wedge block 13 between the support part 11 and the support rod 10 with screws 14. After the fixation is completed, the support sleeve 8 is threadedly installed on the top of the support frame 7 through the mounting hole b12, and then the support rod 10 is threadedly installed in the mounting hole c16. At the same time, the length of the support frame 7 can also be replaced to adjust the height of the support part 11 on the support rod 10. After the staff completes the installation of the support rod 10, they loosen the locking nuts b5 on the fixing blocks 4 at both ends of the base 3. Under the restriction of the slide groove 2, the staff moves the base 3 along the slide groove 2. When the base 3 is moved to the appropriate position, that is, the inclined surface of the support part 11 is in contact with the thin-walled part, and the thin-walled part is vertically supported. The staff then tightens the locking nuts b5 to fix the position of the base 3. When supporting vertically, the support rod 10 and the support frame 7 are on the same vertical line, and the force is pressure, thereby ensuring the support rigidity.

[0054] 6. When the thin-walled workpiece is a large-taper workpiece and external support is required for the large-taper workpiece, such as Fig.10 As shown, the staff first places the thin-walled part on the machine tool base 1, and then selects the corresponding wedge block 13 according to the taper size of the thin-walled part, so that the inclined surface of the support part 11 fits the thin-walled part. The staff fixes the wedge block 13 between the support part 11 and the support rod 10 with screws 14. After the fixation is completed, the support sleeve 8 is threadedly installed on the top of the support frame 7 through the mounting hole b12, and then the support rod 10 is threadedly installed in the mounting hole c16. At the same time, the length of the support frame 7 can also be replaced to adjust the height of the support part 11 on the support rod 10. After the staff completes the installation of the support rod 10, they loosen the locking nuts b5 on the fixing blocks 4 at both ends of the base 3.
