Description

Technical Field

[0001] The present invention belongs to the technical field of transmission gear processing, and more specifically, particularly relates to a precision processing device for parts of automation equipment. Background Art

[0002] Precision gear machining is a manufacturing process that requires extremely high precision. It is mainly used to produce various high-precision transmission gears and is widely used in aerospace, automobile, machinery manufacturing and other fields. Precision machining equipment for parts usually requires the following technologies:

[0003] 1. The main body of the machine tool provides a stable supporting structure for the entire machine tool;

[0004] 2. The cutting mechanism drives the tool to move and provides the power required for cutting;

[0005] 3. Feed mechanism, which controls the movement of the tool in the axial direction of the gear to achieve cutting of gears with different tooth widths;

[0006] 4. Cooling and lubrication mechanism: cools the tool and gear blank during the cutting process.

[0007] Gear shaping is the process of machining the spur gear tooth profile by using the meshing motion of the gear shaping cutter and the spur gear blank according to the principle of generating method. The gear shaping cutter is similar to a gear, and has cutting edges on the top and side of the teeth. When the gear shaping cutter reciprocates up and down, it generates relative motion with the spur gear blank, thereby cutting out the spur gear tooth profile. However, the processing process has the following shortcomings:

[0008] 1. The accuracy of gear shaping is greatly affected by the accuracy of machine tools. Gear shaping is carried out tooth by tooth, and the processing errors of each tooth may accumulate. If it cannot be discovered and corrected in time in the later stage of processing, the accuracy of gear processing will decrease, affecting the use of the gear.

[0009] 2. The gears are fixed by bolts, but the gears with more teeth have larger circumferential dimensions and require more bolts to ensure the stability of the fixation. However, increasing the number of bolts may increase the complexity of installation and disassembly, and increase the processing cost. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present invention, thrust is generated on multiple arc extrusion plates through the friction between the conical block and the inclined plate, so that the arc extrusion plates move outward, and at the same time the arc extrusion plates pull the guide rods to extend and retract, and the guide rods guide the movement of the arc extrusion plates. Multiple arc extrusion plates move synchronously, so that the arc extrusion plates squeeze and fix the inner side of the gear body, and fix them according to the center holes of different gears, thereby increasing the adaptability of the equipment itself.

[0016] In the present invention, two driving rods are used to apply thrust to the fixed plate, so that the fixed plate applies thrust to the side end of the auxiliary push plate. The top end of the auxiliary push plate is rotatably connected to the measuring plate, so that the measuring plate rotates around the top end of the supporting plate. The two measuring plates deflect in opposite directions to each other and fit with the processed inner wall of the gear groove. A thread is installed on the inner wall of the conical block, and the interior of the conical block fits with the top end of the slide. The movement of the rack drives the deflection wheel to rotate, and the rotation angle of the deflection wheel is used to detect whether the processing of the gear groove meets the standard.

[0017] In the present invention, the slide moves downward, driving the mounting plate to move downward, the end of the mounting plate is connected to the support plate, the support plate drives the two measuring plates to slide downward and leave the interior of the gear groove, and then the guide rod is pushed upward by the return spring, so that the slide drives the support plate to move upward, and the two measuring plates are inserted into the interior of the next gear groove, thereby preventing the measuring plates from affecting the rotation processing of the gear body.

[0018] In the present invention, by rotating two fixing bolts, the fixing bolts are rotated at the side ends of the slide, the rotation of the fixing bolts adjusts the spacing between the two mounting plates, the ends of the mounting plates slide at the side ends of the support plates, the ends of the two mounting plates leave the side ends of the support plates, the support plates are pushed to move at the ends of the mounting plates, the positions of the support plates are adjusted, and the positions of the two measuring plates are adjusted according to different gears, thereby increasing the flexibility of use.

The two measuring plates 31 deflect in opposite directions to each other and fit with the inner wall of the machined gear groove. At the same time, the measuring plates 31 move, driving the reset spring 26 to move on the side end of the support plate 29, and the support plate 29 drives the conical block 24 to move. A thread is installed on the inner side wall of the conical block 24, and the interior of the conical block 24 fits with the top of the slide 25. The movement of the rack 34 drives the deflection wheel 35 to rotate, and the surface of the mounting cylinder 17 is fixedly installed with a limited side plate 19.

[0028] An auxiliary push plate 32 is rotatably mounted on the bottom end of each measuring plate 31, and a fixed plate 36 is rotatably mounted on the end of each auxiliary push plate 32. A rack 34 is fixedly mounted on the side end of each fixed plate 36, and two driving rods 33 are fixedly mounted on the side end of each fixed plate 36. A deflection wheel 35 is provided on the side end of each fixed plate 36. The deflection wheel 35 is installed inside the support plate 29, and the side end of the slide 25 is slidably connected to the fixed plate 36. At the same time, the fixed plate 36 slides on the side end of the support plate 29. The two measuring plates 31 are symmetrically mounted with each other, and the deflection wheel 35 can rotate by itself. A sensor and a detection module are installed on the side end of the body 11, and the deflection wheel 35 is connected to the detection module through a wiring harness. The side end of the slide 25 is fixedly mounted with a return spring 26, and the two side ends of the slide 25 are rotatably mounted with fixing bolts 28.

[0029] The side end of the mounting tube 17 is rotatably mounted with a threaded rod 18, and the end of the threaded rod 18 is rotatably mounted with a conical block 24. By rotating the threaded rod 18, the threaded rod 18 is rotated at the side end of the mounting tube 17. The surface of the threaded rod 18 is provided with threads, which are docked with the side end of the mounting tube 17. The rotating threaded rod 18 generates thrust on the conical block 24. The threaded rod 18 is freely rotatable at the side end of the conical block 24. The threaded rod 18 will not drive the conical block 24 to rotate, but the threaded rod 18 generates a horizontal thrust on the conical block 24, allowing the conical block 24 to enter the interior of the mounting tube 17. The conical block 24 is conical. The inclined plate 22 is designed to be inclined, and the friction between the conical block 24 and the inclined plate 22 generates thrust on the multiple arc extrusion plates 21. The four side ends of the mounting cylinder 17 are fixedly mounted with guide rods 23, and the bottom end of each arc extrusion plate 21 is fixedly mounted with an inclined plate 22. A hydraulic rod is installed inside the first base 12 and connected with the end of the second base 13. A gear body 16 is movably installed on the surface of the mounting cylinder 17, a guide groove is opened on the surface of the machine body 11, and a third base 14 is provided on the machine body 11. A machining tool 15 is provided on the side end of the third base 14.

[0030] Working principle:

[0031] In the first step, a plurality of driving motors are installed inside the machine body 11, and a processing tool 15 is installed on the side end of the third base 14. The gear body 16 is docked with the surface of the mounting tube 17, and the gear body 16 is sleeved onto the surface of the mounting tube 17. A suitable processing tool 15 is selected and installed on the main shaft of the machine body 11. According to the module, number of teeth, pressure angle and other parameters of the gear body 16, the cutting speed, feed rate and installation angle of the processing tool 15 of the machine body 11 are adjusted. During the processing, the processing tool 15 gradually moves along the axial direction of the gear body 16 to cut out the tooth shape of the entire gear body 16. During the installation process, the threaded rod 18 is rotated to rotate on the side end of the mounting tube 17. The surface of the threaded rod 18 is provided with threads and docked with the side end of the mounting tube 17. The rotating threaded rod 18 is The conical block 24 generates thrust, and the threaded rod 18 is free to rotate at the side end of the conical block 24. The threaded rod 18 will not drive the conical block 24 to rotate, but the threaded rod 18 generates horizontal thrust on the conical block 24, allowing the conical block 24 to enter the interior of the mounting tube 17. The conical block 24 is conical in design and rubs against the side end of the inclined plate 22. The inclined plate 22 is an inclined surface design. Through the friction between the conical block 24 and the inclined plate 22, thrust is generated on multiple arc extrusion plates 21, allowing the arc extrusion plates 21 to move outward. At the same time, the arc extrusion plates 21 pull the guide rods 23 to retract, and the guide rods 23 guide the movement of the arc extrusion plates 21. Multiple arc extrusion plates 21 move synchronously, allowing the arc extrusion plates 21 to squeeze and fix the inner side of the gear body 16. They are fixed according to the center holes of different gears to increase the adaptability of the equipment itself.

[0032] In the second step, the machining tool 15 is driven to move by the third base 14, and the machining tool 15 processes the surface of the gear body 16 to form a latching tooth. The mounting shaft at the side end of the mounting cylinder 17 is driven by the motor to rotate, and the mounting cylinder 17 drives the gear body 16 and the limiting side plate 19 to rotate synchronously. A plurality of evenly distributed grooves are provided on the surface of the limiting side plate 19, and the surface of the rotating limiting side plate 19 contacts the top of the slide 25. The top of the slide 25 is an arc-shaped design. The slide 25 and the surface friction of the limiting side plate 19 push the slide 25 to move downward, so that the slide 25 squeezes the top of the reset spring 26. At the same time, the reset spring 26 is compressed by the force at the side end of the second base 13, and the reset spring 26 always generates an upward force on the slide 25, so that the slide 25 always rubs against the surface of the limiting side plate 19. Through the downward movement of the slide 25, the slide 25 drives the mounting plate 27 to move downward, and the end of the mounting plate 27 is connected to the support plate 29, and the support plate 29 drives the two The measuring plates 31 slide downward and leave the interior of the gear groove, and then the guide rod 23 is pushed upward by the return spring 26, so that the slide 25 drives the support plate 29 to move upward, and the two measuring plates 31 are inserted into the interior of the next gear groove to prevent the measuring plates 31 from affecting the rotation processing of the gear body 16. By rotating the two fixing bolts 28, the fixing bolts 28 are rotated at the side ends of the slide 25. The rotation of the fixing bolts 28 adjusts the spacing between the two mounting plates 27, and the ends of the mounting plates 27 slide at the side ends of the support plates 29, so that the ends of the two mounting plates 27 leave the side ends of the support plates 29, and push the support plates 29 to move at the ends of the mounting plates 27 to adjust the position of the support plates 29. The positions of the two measuring plates 31 are adjusted according to different gears to increase the flexibility of use. At the same time, the fixing bolts 28 are rotated in the opposite direction to fix the position of the mounting plate 27, and the side ends of the support plates 29 are clamped by the mounting plate 27 to fix the position of the support plates 29.

[0033] In the third step, a deflection wheel 35 is installed inside the support plate 29, and the side end of the slide 25 is slidably connected to the fixed plate 36. At the same time, the fixed plate 36 slides on the side end of the support plate 29. The two measuring plates 31 are symmetrically installed with each other. The deflection wheel 35 can rotate by itself. A sensor and a detection module are installed on the side end of the body 11. The deflection wheel 35 is connected to the detection module through a harness. By moving the support plate 29, the support plate 29 drives the two measuring plates 31 to move upward as a whole and enter the processed gear groove. The two driving rods 33 apply thrust to the fixed plate 36, so that the fixed plate 36 applies thrust to the side end of the auxiliary push plate 32, and the top of the auxiliary push plate 32 is connected to the measuring plate 3 The measuring plate 31 is connected by rotation, so that the measuring plate 31 rotates around the top of the supporting plate 29. The two measuring plates 31 deflect in opposite directions to each other and fit with the inner wall of the processed gear groove. At the same time, the measuring plate 31 moves, driving the reset spring 26 to move on the side end of the supporting plate 29. The supporting plate 29 drives the conical block 24 to move. The inner wall of the conical block 24 is provided with a thread. The inside of the conical block 24 fits with the top of the slide 25. The movement of the rack 34 drives the deflection wheel 35 to rotate. The rotation angle of the deflection wheel 35 is used to detect whether the processing of the gear groove meets the standard. When the processed gear has deviations, it can be discovered in time and reprocessed and corrected to ensure the accuracy of the processing of the gear body 16.
