Description

Technical Field

[0001] This utility model belongs to the field of robotics technology and relates to a machining equipment for joint screw nuts of humanoid robots. Background Technology

[0002] The humanoid robot assembly process requires the use of extra-long nuts. The extra-long nuts need to be processed with special processing equipment to process the internal threads. It is necessary to ensure the processing accuracy of the internal threads of the extra-long nuts while improving the processing efficiency.

[0003] Existing equipment for processing ultra-long nuts, such as the Chinese patent application [Authorization Announcement No.: CN205660259U] which discloses a special machine tool for processing internal threads of ultra-long bars, includes a machine tool body. One end of the machine tool body is equipped with a main body, and the opposite end is equipped with a cylinder and a servo motor via a mounting bracket. The main body includes a drive motor, on which a clamping chuck A is mounted, and on the cylinder is a clamping chuck B. A tool holder is positioned between clamping chuck A and clamping chuck B, and a tool head is mounted on the tool holder via a fastening nut. A slide rail is provided on the frame body between the main body and the cylinder, and a fixed fixture is mounted on the slide rail. The fixed fixture is movably connected to the servo motor via a lead screw on the side near the cylinder. The fixed fixture includes a sliding base plate, and the fixed fixture is slidably connected to the slide rail via the sliding base plate. Vertical plates A and B are symmetrically arranged on both sides of the sliding base plate. The upper end of vertical plate A is provided with a "U"-shaped opening, and vertical plate B, corresponding to the "U"-shaped opening, is provided with a clamping chuck C and a tool holder through hole.

[0004] The above structure requires clamping one end of the extra-long bar stock onto the clamping chuck C, with the opposite end positioned on the "U"-shaped opening of the vertical plate A. The limit rod is then used to contact and fix the extra-long bar stock, thus enabling loading. This loading process requires manual positioning of both ends of the extra-long bar stock, resulting in low loading efficiency. Furthermore, only the cutter head on the tool holder processes the extra-long bar stock, necessitating axial movement of the tool along the bar stock during processing. This requires moving the tool from one end to the other for processing, further reducing processing efficiency and impacting overall processing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a humanoid robot joint screw nut processing equipment. The technical problem this invention aims to solve is: how to address the low processing efficiency of existing ultra-long screw nuts when processing internal threads.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A humanoid robot joint screw nut processing equipment includes a frame with two slide blocks slidably mounted laterally on the frame. A processing gap exists between the two slide blocks. One slide block has a rotatable turntable with a chuck. The frame is characterized by a first driving component capable of driving the two slide blocks to move synchronously in the same direction and to move in opposite directions. The other slide block has a center point. The chuck holds a cylindrical tool, one end of which is pressed against the center point. A loading seat is slidably connected longitudinally to the frame between the two slide blocks. A mounting seat for clamping a workpiece is fixed on the loading seat. A second driving component capable of driving the workpiece to rotate is mounted on the mounting seat. The frame also includes a third driving component that drives the loading seat to move the mounting seat between the two slide blocks when the two slide blocks move in opposite directions.

[0008] The workpiece is mounted on the mounting base of the loading seat. Drive component one is activated, causing the two slides to move in opposite directions. At this point, one end of the cylindrical cutter disengages from the center. Drive component three is then activated, driving the loading seat to move the mounting base between the two slides. Drive component one is activated again, bringing the two slides closer together, allowing one end of the cylindrical cutter to pass through the workpiece in the mounting base and press against the center. The turntable drives the cylindrical cutter to rotate, and drive component two also rotates the workpiece on the mounting base. Because the inner diameter of the workpiece is larger than the outer diameter of the cylindrical cutter, the inner wall of the workpiece rotates circumferentially relative to the cylindrical cutter, thus quickly achieving… For machining the inner wall of a workpiece, since the overall length of the cylindrical tool is long enough, when machining the workpiece, it is only necessary to start the drive component to move the two slides synchronously and in the same direction in the transverse direction. The cylindrical tool moves a distance of one pitch relative to the workpiece to complete the machining. Furthermore, through the cooperation of the center and the chuck, the axial positioning of the cylindrical tool during the machining process and the synchronous rotation of the cylindrical tool and the workpiece are realized, which facilitates fast and stable machining of the workpiece. The use of multi-axis linkage during machining allows the cylindrical tool to be inserted into the workpiece for machining, which can further improve the machining efficiency.

[0009] Both drive component one and drive component three are cylinders. The slide block is slidably connected to the frame via a nut and screw. The loading seat is slidably connected to the frame via a nut and screw.

[0010] In the aforementioned humanoid robot joint screw nut processing equipment, the outer wall of the cylindrical cutter has multiple parallel and annular cutting edges, both slides slide laterally along the central axis of the cylindrical cutter, and the central axis of the tip is coaxial with the central axis of the chuck.

[0011] The cutting edge is designed to facilitate simultaneous machining of the inner wall of the workpiece. To ensure the stability of the cylindrical tool during lateral movement, the center axis of the tip is set coaxially with the center axis of the chuck, thereby improving the accuracy of the cylindrical tool during movement and thus improving machining precision while meeting the requirements of rapid machining.

[0012] In the aforementioned humanoid robot joint screw nut processing equipment, one end of the cylindrical cutter is provided with a positioning groove along the axial direction, and the end face of the tip is conical, which is inserted into the positioning groove.

[0013] The center is inserted into the positioning groove along the transverse direction. After the two slides move away from each other, the cylindrical tool can quickly disengage. The conical surface serves two purposes: firstly, it limits the circumferential position of the cylindrical tool end; secondly, when machining different workpieces, only cylindrical tools of different sizes need to be replaced, thus improving the practicality of the center.

[0014] In the aforementioned humanoid robot joint screw nut processing equipment, two slides are equipped with rotary motors. The motor shaft of one rotary motor is fixedly connected to the turntable, and the motor shaft of the other rotary motor is fixedly connected to the center.

[0015] The rotary motor drives the turntable to rotate the chuck, enabling the cylindrical tool to machine the workpiece. A slide with a center point can be driven to move towards another slide, bringing one end of the cylindrical tool against the center point. Because the cylindrical tool is quite long, the driving force of a single rotary motor is insufficient. By using two slides, each with a rotary motor, the cylindrical tool is driven from both ends. The method of having the center point against the cylindrical tool ensures that even slight asynchrony between the two drive motors does not affect the cutting process, thus improving cutting efficiency while maintaining cutting accuracy.

[0016] In the aforementioned humanoid robot joint screw nut processing equipment, a tensioning tube is slidably inserted into the mounting base along the lateral direction. A tubular tensioning head is inserted inside the tensioning tube, and a clamping spring is connected inside the tensioning tube. One end of the tensioning head has an outer conical surface on its side wall, and a limit stop ring is sleeved on the other end of the tensioning head. One end of the clamping spring abuts against the limit stop ring, and the elastic force of the clamping spring can cause the tensioning head to move axially inward relative to the tensioning tube and clamp the workpiece.

[0017] The workpiece is first inserted into the tension tube. The tensioning head moves axially inward relative to the tensioning tube by the elastic force of the clamping spring, thus clamping the workpiece. When the tensioning head moves outward, the limiting ring on the tensioning head pushes the clamping spring to compress axially, which facilitates the rapid clamping and positioning of the next workpiece, improves the positioning efficiency of the workpiece, and thus improves the processing efficiency of the processing equipment.

[0018] In the aforementioned humanoid robot joint screw nut processing equipment, the mounting base is also equipped with a drive cylinder that can be fixedly connected to the other end of the tensioning head. The drive cylinder can drive the tensioning head to move outward along the axial direction.

[0019] After the workpiece is processed, it needs to be unloaded. A drive cylinder is installed on the mounting base. The drive cylinder drives the tensioning head to move axially, so that the tensioning head moves outward along the axis, releasing the positioning of the workpiece, thereby realizing the rapid unloading of the workpiece. During the movement, the drive cylinder also compresses the clamping spring, which improves the unloading efficiency of the workpiece.

[0020] In the aforementioned humanoid robot joint screw nut processing equipment, one end of the tensioning head has multiple axially opened breaks, which penetrate the side wall of the tensioning head radially, and the multiple breaks are evenly distributed along the circumference of the tensioning head.

[0021] As the tensioning head moves axially inward relative to the tensioning tube, the break gradually closes, achieving radial contraction at one end of the tensioning head. This facilitates the positioning of the workpiece, ensures that the contact area between the workpiece and the tensioning head is maintained at a large level during positioning, and improves the stability of workpiece positioning.

[0022] In the aforementioned humanoid robot joint screw nut processing equipment, the second driving component is a drive motor, one end of the tensioning tube is fixedly connected to a driven gear, the drive gear is sleeved on the motor shaft of the drive motor, and the drive gear drives the driven gear to rotate through a belt.

[0023] The structure of belt, drive gear, and driven gear allows the drive motor to be positioned on the outside of the tension tube, rather than along its axis. This is useful when installing workpieces, especially those that are long enough to extend beyond the tension tube. The belt, drive gear, and driven gear design allows for better workpiece positioning, resulting in more stable installation and facilitating subsequent stable processing.

[0024] In the aforementioned humanoid robot joint screw nut processing equipment, the loading seat includes a base plate that can move longitudinally along the frame. One end of the base plate is fixed with a tool dressing mechanism, and the other end is fixed with the aforementioned mounting seat. The tool dressing mechanism includes a dressing seat and a grinding wheel that is rotatably connected to the dressing seat and can dress the cylindrical tool.

[0025] Because multiple cutting edges of a cylindrical tool simultaneously process the internal threads of the workpiece during circumferential rotation, the cylindrical tool encounters significant resistance during processing. Therefore, to ensure stable processing of all workpieces, a tool dressing mechanism is installed on the base plate of the loading seat. The grinding wheel of the tool dressing mechanism is used to dress the cylindrical tool, and the grinding wheel is rotatably connected to the dressing seat. Therefore, the angle of the grinding wheel can be finely adjusted before dressing to improve the dressing effect of the cylindrical tool, thereby improving the processing accuracy of the processing equipment.

[0026] In the aforementioned humanoid robot joint screw nut processing equipment, an adjusting rod is hinged to the upper part of the dressing seat, a support frame is hinged to the middle part of the dressing seat, a dressing motor is provided on the support frame, the middle part of the grinding wheel is fixedly connected to the motor shaft of the dressing motor, a connecting sleeve is rotatably connected to the support frame, the middle part of the adjusting rod passes through the connecting sleeve, and the lower end of the adjusting rod is suspended in the air.

[0027] When the angle of the grinding wheel needs to be adjusted, simply hold the lower end of the adjusting rod and swing it along the hinge between the upper end of the adjusting rod and the dressing seat. The support frame will also swing along the hinge point with the dressing seat as the adjusting rod swings, thus achieving stable fine-tuning of the dressing seat and making the adjustment more convenient and quick.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] 1. Because the overall length of the cylindrical tool is long enough, it only needs to rotate once or twice when machining the workpiece, which can realize the rapid machining of the internal thread of the workpiece. Furthermore, through the cooperation of the center and the chuck, that is, the cooperation of the fixture positioning and the center positioning, the axial positioning of the cylindrical tool during the machining process is realized, as well as the synchronous rotation of the cylindrical tool and the workpiece, which facilitates the rapid and stable machining of the workpiece.

[0030] 2. When the workpiece is clamped, the tensioning head moves inward relative to the tensioning tube by the elastic force of the clamping spring, thus clamping the workpiece. When the workpiece is released from positioning, a drive cylinder is set on the mounting base. The drive cylinder pushes the tensioning head outward relative to the tensioning tube, thus releasing the positioning of the workpiece. This enables the rapid loading and unloading of workpieces and improves the efficiency of workpiece loading and unloading.

[0031] 3. Because multiple cutting edges of the cylindrical tool simultaneously process the internal threads of the workpiece when it rotates circumferentially, the cylindrical tool encounters greater resistance during processing. Therefore, in order to ensure stable processing of the workpiece, a tool dressing mechanism is set on the base plate of the loading seat. The cylindrical tool is dressed by the grinding wheel of the tool dressing mechanism, and the grinding wheel is rotatably connected to the dressing seat. Therefore, the angle of the grinding wheel can be finely adjusted before dressing to improve the dressing effect of the cylindrical tool, thereby improving the processing accuracy of the processing equipment.

[0042] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0043] like Figure 1As shown, the humanoid robot joint screw nut processing equipment includes a frame 1, two slide blocks 2 are slidably arranged on the frame 1 along the lateral direction, and there is a processing gap 3 between the two slide blocks 2. One of the slide blocks 2 is equipped with a rotatable turntable 21, and a chuck 22 is provided on the turntable 21.

[0044] Specifically, such as Figure 2-5 As shown, the frame 1 is also equipped with a drive component 11 that can drive the two slides 3 to move synchronously in the same direction and move relatively in opposite directions. The other slide 2 is equipped with a center point 23, and a chuck 22 holds a cylindrical cutter 4. One end of the cylindrical cutter 4 is pressed against the center point 23. A loading seat 5 located between the two slides 2 is slidably connected to the frame 1 along the longitudinal direction. A mounting seat 6 that can hold the workpiece 7 is fixed on the loading seat 5. A drive component 61 that can drive the workpiece 7 to rotate is provided on the mounting seat 6. The frame 1 is also equipped with a drive component 3 12 that can drive the loading seat 5 to move the mounting seat 6 to the space between the two slides 2 when the two slides 2 are separated.

[0045] The workpiece 7 is mounted on the mounting base 6 of the loading seat 5. The first drive unit 11 is activated, causing the two slides 2 to move in opposite directions. At this time, one end of the cylindrical cutter 4 disengages from the center 23. The third drive unit 12 is then activated, driving the loading seat 5 and the mounting base 6 to move between the two slides 2. The first drive unit 11 is activated again, bringing the two slides 2 closer together, allowing one end of the cylindrical cutter 4 to pass through the workpiece 7 inside the mounting base 6 and press against the center 23. The turntable 21 drives the cylindrical cutter 4 to rotate, and the second drive unit 61 also drives the workpiece 7 on the mounting base 6 to rotate. Since the inner diameter of the workpiece 7 is larger than the outer diameter of the cylindrical cutter 4, the inner wall of the workpiece 7 rotates circumferentially relative to the cylindrical cutter 4. This allows for rapid machining of the inner wall of workpiece 7. Since the overall length of the cylindrical tool 4 is long enough, when machining workpiece 7, it is only necessary to start the drive component 11 to move the two slide blocks 2 synchronously and in the same direction in the transverse direction. The cylindrical tool 4 moves a distance of one pitch relative to workpiece 7 to complete the machining of workpiece 7. Furthermore, through the cooperation of the center 23 and the chuck 22, the axial positioning of the cylindrical tool 4 during the machining process and the synchronous rotation of the cylindrical tool 4 and workpiece 7 are achieved, which facilitates the rapid and stable machining of workpiece 7. The use of multi-axis linkage during machining allows the cylindrical tool 4 to be inserted into workpiece 7 for machining, which can further improve machining efficiency.

[0046] Both drive component 11 and drive component 32 are cylinders. The slide block 2 is slidably connected to the frame 1 via a nut and screw. The loading seat 5 is slidably connected to the frame 1 via a nut and screw.

[0047] like Figure 2 and Figure 3As shown, the outer wall of the cylindrical cutter 4 has multiple parallel and annular cutting edges 42. Both slides 2 slide laterally along the central axis of the cylindrical cutter 4. The central axis of the tip 23 is coaxial with the central axis of the chuck 22. One end of the cylindrical cutter 4 has a positioning groove 41 along the axial direction. The end face of one end of the tip 23 is conical and is inserted into the positioning groove 41. Both slides 2 are equipped with rotary motors 24. The motor shaft of one rotary motor 24 is fixedly connected to the turntable 21, and the motor shaft of the other rotary motor 24 is fixedly connected to the tip 23.

[0048] like Figure 5-8 As shown, a tensioning tube 62 is slidably inserted into the mounting base 6 along its lateral direction. A tubular tensioning head 63 passes through the tensioning tube 62, and a clamping spring 65 is connected inside the tensioning tube 62. One end of the tensioning head 63 has an outer conical surface 63a on its sidewall, and a limit ring 63b is sleeved on the other end of the tensioning head 63. One end of the clamping spring 65 abuts against the limit ring 63b. The elastic force of the clamping spring 65 can cause the tensioning head 63 to move axially inward relative to the tensioning tube 62 and clamp the workpiece 7. The mounting base 6 is also provided with another... The drive cylinder 64 is fixed to the end and can drive the tensioning head 63 to move outward along the axial direction. One end of the tensioning head 63 has multiple axially opened breaks 63c. The breaks 63c penetrate the side wall of the tensioning head 63 radially. The multiple breaks 63c are evenly distributed around the tensioning head 63. The second drive component 61 is a drive motor. One end of the tensioning tube 62 is fixedly connected to a driven gear 62a. The drive gear 61a is sleeved on the motor shaft of the drive motor. The drive gear 61a drives the driven gear 62a to rotate through the belt 66.

[0049] like Figure 1 and Figure 9 As shown, the feeding seat 5 includes a base plate 51 that can move longitudinally along the frame 1. One end of the base plate 51 is fixed with a tool dressing mechanism 8, and the other end is fixed with the aforementioned mounting seat 6. The tool dressing mechanism 8 includes a dressing seat 81 and a grinding wheel 82 that is rotatably connected to the dressing seat 81 and can dress the cylindrical tool 4. An adjusting rod 83 is hinged to the upper part of the dressing seat 81, and a support frame 84 is hinged to the middle part of the dressing seat 81. A dressing motor 85 is provided on the support frame 84. The middle part of the grinding wheel 82 is fixedly connected to the motor shaft of the dressing motor 85. A connecting sleeve 84a is rotatably connected to the support frame 84.
