Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to an internal support tooling. Background Technology

[0002] Internal support clamping tools are tools used to assist CNC lathes in precision machining of the inner diameters of various product types, such as motors, optical lenses, medical and security products, and various material types, such as ADC12, aluminum alloys, copper, magnesium alloys, and iron.

[0003] In machining processes, thin-walled parts are often encountered. Due to their lower structural strength, thin-walled parts are more difficult to clamp. When thin-walled parts need to be machined with conical surfaces or milled steps on their outer surfaces, the machining difficulty is even greater. Furthermore, some parts need to be machined when tilted at a certain angle. To prevent the fixture and tool from colliding and damaging the tool when turning the outer diameter, internal support clamping is often used to fix the part when machining the outer surface of the workpiece. However, traditional internal support fixtures are prone to concentricity problems, resulting in poor product clamping and affecting the product's concentricity. Specifically, the internal support parts of the fixture will tilt, making it impossible to guarantee the required tolerance for the concentricity of the inner diameters at both ends of the part, and it is inconvenient to rotate the part at a certain angle after internal support clamping for machining. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides an internal support tooling.

[0005] This application provides an internal support fixture, which adopts the following technical solution:

[0006] An internal support fixture includes a support plate with multiple slide rails evenly arranged on the support plate. A slider is slidably mounted on each slide rail, and an internal support member is provided on the top of the slider. A mounting base is provided at the bottom of the support plate, and a driven gear is rotatably mounted on the mounting base. The driven gear has multiple arc-shaped through slots evenly opened on it. The bottom of the slider is slidably mounted in the through slots. The ends of the multiple slide rails are fixedly mounted on the mounting base. A drive assembly for driving the driven gear to rotate is provided on the mounting base. A base is provided at the bottom of the mounting base, and a rotating shaft is provided on the mounting base. The rotating shaft is rotatably mounted on the base, and an adjustment assembly for adjusting the rotation angle of the rotating shaft is provided on the base.

[0007] By adopting the above technical solution, the driven gear is driven to rotate by the drive component, thereby pushing the slider to move along the length of the slide rail, and thus clamping the workpiece to be processed internally; by adjusting the tilt angle of the support plate and the mounting base, the tilt angle of the workpiece to be processed can be adjusted, thereby facilitating better machining of the parts to be processed.

[0008] Optionally, the drive assembly includes a drive gear, which is rotatably mounted on a mounting base via a power shaft and meshes with a driven gear. A worm gear is coaxially mounted on the bottom of the power shaft, and a worm is rotatably mounted on the mounting base, meshing with the worm gear. A drive motor is fixedly mounted on the mounting base, and the output shaft of the drive motor is coaxially connected to the worm.

[0009] By adopting the above technical solution, the drive motor is started, thereby driving the driven gear to rotate, and then controlling the movement of multiple inner support components to clamp the workpiece to be processed.

[0010] Optionally, the adjustment assembly includes an adjustment gear, which is coaxially mounted on a rotating shaft. A sliding groove is provided on the base, and an adjustment block is slidably disposed in the sliding groove. A rack is provided on the adjustment block, and the rack meshes with the adjustment gear. A lead screw is rotatably disposed on the base along the length of the sliding groove, and the lead screw is threadedly connected to the adjustment block. A handwheel is coaxially disposed at one end of the lead screw.

[0011] By adopting the above technical solution, the operator turns the handwheel, which drives the lead screw to rotate, thereby driving the rack to move. As the rack moves, it pushes the adjusting gear to rotate, which in turn drives the rotating shaft to rotate synchronously. As the rotating shaft rotates, it drives the support plate and the mounting base to rotate synchronously, thereby adjusting the tilt angle of the part to be processed.

[0012] Optionally, the end of the lead screw is provided with a first polygonal insertion hole, and a plug rod is coaxially provided on the handwheel, with a plug block at the end of the plug rod for insertion into the insertion hole.

[0013] By adopting the above technical solution, it is easy to remove the handwheel when not in use.

[0014] Optionally, a connecting shaft is coaxially provided at one end of the worm gear, and a second insertion hole is provided on the connecting shaft. The shape and size of the second insertion hole are the same as those of the first insertion hole, and an installation groove is provided on the base.

[0015] By adopting the above technical solution, workers can manually control the rotation of the drive assembly, thereby controlling the fixation of the inner support block on the workpiece to be processed.

[0016] Optionally, the base has a slag discharge port at its bottom, and the interior of the base is provided with an inclined block to facilitate the slag falling into the slag discharge port.

[0017] By adopting the above technical solution, the waste generated after the parts to be processed will fall onto the inclined block inside the base, and under the action of the waste's own gravity, it will be discharged from the inner cavity of the base through the slag discharge port.

[0018] Optionally, the base is provided with a plurality of fixing bolts for fixing itself.

[0019] By adopting the above technical solution, the base is fixedly installed on the processing table by fixing bolts, which facilitates the processing of the parts to be processed.

[0020] Optionally, an anti-slip pad is provided on the outer wall of the inner support member.

[0021] By adopting the above technical solution, the anti-slip pad can increase the friction between the inner support and the workpiece to be processed, thereby improving the inner support and fixing effect of the inner support on the workpiece to be processed, and thus improving the stability of the workpiece to be processed during the processing.

[0022] This utility model has the following advantages:

[0023] 1. By setting up drive components and adjustment components, the tilt angle of the workpiece can be adjusted after the workpiece is fixed, thereby facilitating better machining of the workpiece.

[0024] 2. By installing a plug and a plug block on the handwheel, the handwheel and the lead screw can be detachably connected;

[0025] 3. By setting anti-slip pads on the inner wall of the inner support, the friction between the inner support and the workpiece to be processed can be increased, thereby improving the inner support and fixing effect of the inner support on the workpiece to be processed.

[0030] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0031] like Figures 1 to 3 As shown, an internal support fixture includes a support plate 1. Multiple slide rails 11 are evenly mounted on the support plate 1. Slider blocks 12 are slidably mounted on the slide rails 11. An internal support member 13 is mounted on the top of each slider 12. The internal support member 13 is composed of arc-shaped blocks with different radii, enabling internal clamping of workpieces of different sizes. A mounting base 14 is mounted on the bottom of the support plate 1. A driven gear 15 is rotatably mounted on the mounting base 14. The multiple slide rails 11 are evenly arranged along the circumference of the driven gear 15. Multiple arc-shaped through slots 151 are evenly formed on the driven gear 15. Multiple sliders 12 correspond one-to-one with the multiple through slots 151. The bottom of each slider 12 is slidably mounted within the through slot 151. The ends of the multiple slide rails 11 are fixedly mounted on the mounting base 14. A drive assembly 2 for driving the driven gear 15 to rotate is mounted on the mounting base 14. A bottom support is mounted on the bottom of the mounting base 14. The base 16 has a rotating shaft 161 mounted on it, and the rotating shaft 161 is rotatably mounted on the base 16. The base 16 has an adjustment component 3 for adjusting the rotation angle of the rotating shaft 161. In use, the operator places the workpiece to be processed on multiple inner support members 13, and then drives the driven gear 15 to rotate through the drive component 2. During the rotation of the driven gear 15, the slider 12 will slide along its corresponding arc-shaped through groove 151, thereby pushing the slider 12 to move along the length direction of the slide rail 11. During the movement of the slider 12, the inner support members 13 will move synchronously. Multiple inner support members 13 will move synchronously, thereby clamping the workpiece to be processed. By adjusting the tilt angle of the support plate 1 and the mounting base 14 through the adjustment component 3, the tilt angle of the workpiece to be processed can be adjusted, thereby facilitating better machining of the workpiece.

[0032] like Figures 1 to 3As shown, the drive assembly 2 includes a drive gear 21, which is rotatably mounted on the mounting base 14 via a power shaft 22. The drive gear 21 meshes with the driven gear 15. A worm gear 24 is coaxially mounted on the bottom of the power shaft 22. A worm 25 is rotatably mounted on the mounting base 14, meshing with the worm gear 24. A drive motor 26 is fixedly mounted on the mounting base 14, and the output shaft of the drive motor 26 is coaxially connected to the worm gear 25. In use, the drive motor 26 is started, and during its rotation, the drive motor 26 drives the worm gear 25 to rotate. During the rotation of the worm gear 25, the worm gear 24 rotates, and during the rotation of the worm gear 24, the power shaft 22 rotates. Simultaneously, the power shaft 22 rotates, driving the drive gear 21 to rotate. During the rotation of the drive gear 21, the driven gear 15 rotates, thereby controlling the movement of multiple inner support members 13. By using the worm gear 24 and the worm gear 25, a certain self-locking effect can be achieved, which facilitates the clamping and fixing of the parts to be processed.

[0033] like Figures 1 to 3 As shown, the adjustment assembly 3 includes an adjustment gear 31, which is coaxially mounted on a rotating shaft 161. A groove 32 is provided on the base 16, and an adjustment block 33 is slidably installed within the groove 32. A rack 34 is mounted on the adjustment block 33, meshing with the adjustment gear 31. A lead screw 35 is rotatably mounted on the base 16 along the length of the groove 32, and is threadedly connected to the adjustment block 33. A handwheel 36 is coaxially mounted on one end of the lead screw 35. In use, the operator rotates the handwheel 36, which in turn drives the lead screw 35 to rotate, and the rotation of the lead screw 35 drives the adjustment block 33 to rotate along the groove 32. As the slide 32 moves along its length, the adjusting block 33 moves synchronously, driving the rack 34 to move as well. The rack 34 then drives the adjusting gear 31 to rotate, which in turn drives the rotating shaft 161 to rotate synchronously. This rotation of the shaft 161 then drives the support plate 1 and the mounting base 14 to rotate synchronously, thereby adjusting the tilt angle of the workpiece. After the operator releases the handwheel 36, the adjusting block 33 and the rack 34 cannot move freely due to the threaded connection between them, thus achieving a self-locking effect and facilitating the machining of the workpiece.

[0034] like Figures 1 to 3As shown, the end of the lead screw 35 has a polygonal first insertion hole 4. A plug rod 41 is coaxially mounted on the handwheel 36, and the end of the plug rod 41 is fitted with a plug block 42 for insertion into the insertion hole. When the operator needs to drive the lead screw 35 to rotate, the operator inserts the plug block 42 on the handwheel 36 into the first insertion hole 4, thereby connecting the handwheel 36 and the lead screw 35. During the operation of the operator, the lead screw 35 will be driven to rotate synchronously. When the operator adjusts the part to be processed to a suitable position, the handwheel 36 is removed, thereby making the area around the base 16 clean and facilitating the processing of the part to be processed.

[0035] like Figures 1 to 3 As shown, a connecting shaft 43 is coaxially mounted on one end of the worm gear 25. A second insertion hole 44 is provided on the connecting shaft 43. The shape and size of the second insertion hole 44 are the same as those of the first insertion hole 4. An installation groove 45 is provided on the base 16. When the support plate 1 is in a horizontal position, the operator inserts the plug 42 on the handwheel 36 into the second insertion hole 44. When the operator rotates the handwheel 36, it will drive the worm gear 25 to rotate synchronously, so that the operator can manually control the rotation of the drive assembly 2, thereby controlling the fixation of the inner support block on the workpiece to be processed. The installation groove 45 allows the connecting shaft 43 to not affect the normal rotation of the support plate 1 when the tilt angle of the support plate 1 is adjusted by the adjustment assembly 3.

[0036] like Figures 1 to 3 As shown, a slag discharge port 46 is provided at the bottom of the base 16, and an inclined block 47 is installed inside the base 16 to facilitate the falling of waste slag into the slag discharge port 46. When the operator adjusts the tilt angle of the support plate 1, the inner support 13 and the workpiece to be processed by adjusting the component 3, the waste generated after the workpiece to be processed will fall onto the inclined block 47 inside the base 16. Under the action of the waste's own gravity, it will be discharged from the inner cavity of the base 16 through the slag discharge port 46.

[0037] like Figures 1 to 3 As shown, multiple fixing bolts 48 are evenly installed on the base 16 for fixing itself; the base 16 is fixedly installed on the processing table by fixing bolts 48, so as to facilitate the processing of the parts to be processed.

[0038] like Figures 1 to 3 As shown, an anti-slip pad 49 is installed on the outer wall of the inner support member 13. The anti-slip pad 49 can increase the friction between the inner support member 13 and the workpiece to be processed, thereby improving the inner support member 13's internal support and fixing effect on the workpiece to be processed, and thus improving the stability of the workpiece to be processed during the processing. In this embodiment, the anti-slip pad 49 is made of rubber. In other embodiments, the anti-slip pad 49 can also be made of silicone or other materials.

[0039] The implementation principle of this embodiment is as follows: In use, the operator places the workpiece to be processed on multiple inner support members 13, and then drives the driven gear 15 to rotate through the drive component 2. During the rotation of the driven gear 15, the slider 12 will slide along its corresponding arc-shaped through groove 151, thereby pushing the slider 12 to move along the length direction of the slide rail 11. During the movement of the slider 12, the inner support members 13 will move synchronously. Multiple inner support members 13 will move synchronously, thereby clamping the workpiece to be processed. By adjusting the tilt angle of the support plate 1 and the mounting base 14 through the adjustment component 3, the tilt angle of the workpiece to be processed can be adjusted, thereby facilitating better machining of the parts to be processed.

[0040] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
