Description

Technical Field

[0001] This utility model belongs to the technical field of clamping mechanism, and relates to a tool clamping mechanism for a humanoid robot joint screw nut processing equipment. 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 adjusted to contact and fix the extra-long bar stock, thus enabling the loading of the extra-long bar stock. The double chuck structure requires ensuring the coaxiality of the extra-long bar stock during clamping, which makes it difficult to adjust the loading accuracy of the extra-long bar stock, affecting the loading efficiency and the accuracy of subsequent processing. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a tool clamping mechanism for a humanoid robot joint lead screw nut processing equipment. The technical problem to be solved by this utility model is: how to solve the problem of difficulty in clamping existing tools while ensuring installation accuracy.

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

[0007] A tool clamping mechanism for a humanoid robot joint screw nut processing equipment is disclosed. The joint screw nut processing equipment includes a frame, and the tool clamping mechanism includes two slide blocks that slide laterally along the frame. The mechanism is characterized in that each slide block has a mounting base fixed to it. One mounting base is rotatably connected to a turntable, which has a chuck. The other mounting base has a center point, which is coaxially opposite to the center point. The tool is cylindrical, with one end inserted and fixed to the chuck, and the center point abutting against the other end of the tool. The frame also includes a drive component capable of driving the two slide blocks to move synchronously in the same direction and to move in opposite directions.

[0008] One end of the cutting tool is held in place by a chuck, and the other end is held in place by a center. During machining, the drive mechanism is activated to move the two slides in opposite directions to create space for the workpiece. Then, the two slides are brought together so that one end of the cutting tool passes through the workpiece and is held in place by the center. During machining, the chuck is rotated by a turntable, and the center holds the other end of the cutting tool in place, thus rotating the cutting tool and machining the workpiece. When machining the internal threads of the workpiece, the two slides need to move synchronously in the same direction to facilitate the machining of the internal threads and improve machining efficiency. The method of holding the tool at one end and holding it in place at the other end makes the installation and positioning of the cutting tool more convenient. Furthermore, the synchronous movement of the slides in the same direction and in opposite directions improves the movement accuracy of the cutting tool, resulting in more accurate machining of the workpiece.

[0009] In the tool clamping mechanism of the aforementioned humanoid robot joint screw nut processing equipment, two mounting bases 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.

[0010] By using rotary motors to drive the tool's rotation at both ends, the tool's driving force is increased, further ensuring stable machining.

[0011] In the tool clamping mechanism of the aforementioned humanoid robot joint screw nut processing equipment, one end of the tool is embedded in the chuck and threadedly connected to the chuck, and the other end has a positioning groove along its own axial direction. The end face of the tip is conical and is inserted into the positioning groove.

[0012] The center is inserted into the positioning groove along the transverse direction. After the two slides move away from each other, the tool can quickly disengage. The conical surface serves two purposes: firstly, it limits the circumferential movement of the tool tip; secondly, when machining different workpieces, only tools of different sizes need to be replaced; and thirdly, it reduces the friction between the tool and the center, thus improving the practicality of the center.

[0013] In the tool clamping mechanism of the aforementioned humanoid robot joint lead screw nut processing equipment, the frame is provided with slide rails that correspond one-to-one with the slide block in the transverse direction. The slide block is provided with a slider that is slidably connected to the slide rail. The frame is rotatably connected with a lead screw that corresponds one-to-one with the slide block. The driving component is a drive motor. The motor shaft of the drive motor is connected to the lead screw and drives the lead screw to rotate. The bottom of the slide block is provided with a connecting block that is threaded to the lead screw.

[0014] By setting up slide rails, sliders, lead screws, and slide blocks, the stability of the slide block's lateral movement is ensured, preventing deviations in other directions. Furthermore, since the mounting base needs to house components such as rotary motors, a combination of slide rails and lead screws is used to ensure stable drive, which satisfies both movement accuracy and improves movement efficiency.

[0015] In the tool clamping mechanism of the aforementioned humanoid robot joint lead screw nut processing equipment, the two lead screws are coaxially arranged, and two slide rails are provided under each slide block. The slide rails on the same side of the two slide blocks are coaxially arranged.

[0016] With this structure, the lead screws and slide rails of the two slides are coaxially arranged, further improving the accuracy of the movement of the two slides.

[0017] In the tool clamping mechanism of the aforementioned humanoid robot joint screw nut processing equipment, both slide blocks slide laterally along the central axis of the tool, and the central axis of the tip is coaxial with the central axis of the chuck.

[0018] By setting the center axis of the tip to be coaxial with the center axis of the chuck, the accuracy of the tool during movement is improved, thereby improving machining precision while meeting the requirements of rapid machining.

[0019] Compared with the prior art, this utility model has the following advantages: During processing, the turntable drives the chuck to rotate, at which point the center clamps the other end of the tool, realizing the rotation of the tool and thus processing the workpiece. In the process of machining the internal thread of the workpiece, the two slides need to move synchronously in the same direction to facilitate the machining of the internal thread of the workpiece and improve the machining efficiency. The method of clamping at one end and clamping at the other end makes the installation and positioning of the tool more convenient. Furthermore, the synchronous movement of the slides in the same direction and synchronous reverse movement can improve the movement accuracy of the tool, making the machining accuracy of the workpiece more accurate.

Detailed Implementation

[0025] 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.

[0026] like Figure 1 As shown, the tool clamping mechanism of the humanoid robot joint screw nut processing equipment includes a frame 1, and the tool clamping mechanism includes two slide blocks 2 that are slidably arranged along the frame 1.

[0027] Specifically, such as Figure 1-3 As shown, each of the two slides 2 is fixed with a mounting base 27. One mounting base 27 is rotatably connected to a turntable 21, and a chuck 22 is provided on the turntable 21. The other mounting base 27 is provided with a center point 25. The chuck 22 and the center point 25 are coaxially opposite each other. The tool 4 is cylindrical, and one end is inserted and fixed on the chuck 22. The center point 25 is pressed against the other end of the tool 4. The frame 1 is also provided with a drive unit 3 that can drive the two slides 2 to move synchronously in the same direction and move relatively in opposite directions. Both slides 2 slide laterally along the central axis of the tool 4. The central axis of the center point 25 is coaxial with the central axis of the chuck 22.

[0028] One end of the cutting tool 4 is held by the chuck 22, and the other end is held by the center point 25. During machining, the drive unit 3 needs to be activated to move the two slides 2 in opposite directions to make room for the workpiece. Then, the two slides 3 are brought together so that one end of the cutting tool 4 passes through the workpiece and is held by the center point 25. During machining, the turntable 21 drives the chuck 22 to rotate. At this time, the center point 25 holds the other end of the cutting tool 4, realizing the rotation of the cutting tool 4 and machining the workpiece. During the machining of the internal thread of the workpiece, the two slides 2 need to move synchronously in the same direction to facilitate the machining of the internal thread of the workpiece and improve the machining efficiency. The method of holding at one end and holding at the other end makes the installation and positioning of the cutting tool 4 more convenient. Furthermore, the synchronous movement of the slides 2 in the same direction and synchronous reverse movement can improve the movement accuracy of the cutting tool 4, making the machining accuracy of the workpiece more accurate.

[0029] like Figure 2 As shown, each of the two mounting bases 27 is equipped with a rotary motor 26. The motor shaft of one rotary motor 26 is fixedly connected to the turntable 21, and the motor shaft of the other rotary motor 26 is fixedly connected to the tip 25. One end of the cutter 4 is embedded in the chuck 22 and threadedly connected to the chuck 22. The other end is provided with a positioning groove 41 along its own axial direction. The end face of one end of the tip 25 is conical and is inserted into the positioning groove 41.

[0030] like Figure 3 and Figure 4 As shown, the frame 1 is provided with slide rails 11 that correspond one-to-one with the slides 2 in the transverse direction. The slides 2 are provided with sliders 23 that are slidably connected to the slide rails 11. The frame 1 is rotatably connected with lead screws 12 that correspond one-to-one with the slides 2. The driving component is a drive motor. The motor shaft of the drive motor is connected to the lead screw 12 and drives the lead screw 12 to rotate. The bottom of the slides 2 is provided with a connecting block 24 that is threaded to the lead screw 12. The two lead screws 12 are coaxially arranged. The two slide rails 11 mentioned above are provided below each slide 2. The slide rails 11 on the same side of the two slides 2 are coaxially arranged.

[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
