Description

Technical Field

[0001] This application relates to the field of machine tool head manufacturing, and in particular to a guide bar disc for a guide bar machine. Background Technology

[0002] With the improvement of automation level in manufacturing, the demand for automation in the tool production process is increasing. Currently, after the tool head is produced, it needs to be placed in a coating furnace for coating treatment. The coating can improve the hardness and wear resistance of the tool head. The tool heads are connected in series by a connecting rod, and adjacent tool heads are separated by springs, thereby improving the neatness of the tool heads and the number of tool heads that the coating furnace can accommodate. The existing tool connecting machine can only alternately place springs and tool heads on a single connecting rod to perform the tool connecting operation through the spring placement device and the tool head placement device.

[0003] Based on the structure of the cascading cutter machine, the spring placement device and the cutter head placement device are now divided into dual-station states, so that the cascading cutter machine can sequentially place the springs and cutters on different cascading rods, thereby realizing step-by-step operation of multiple cascading rods. There is an urgent need for a multi-cascading rod installation structure that can be adapted to dual-station reciprocating motion. Utility Model Content

[0004] To accommodate the dual-station configuration of the spring placement device and the cutter head placement device, this application provides a rod plate for a tool stringing machine.

[0005] This application provides a rod holder for a bar threading machine, which adopts the following technical solution: A rod-stringing disc for a knife-stringing machine includes a frame, a rotating disc, a plurality of rods, and a drive motor. The axis of the rotating disc is vertically arranged, and the drive motor is mounted on the frame. The drive motor drives the rotating disc to rotate at intervals. The rods are vertically arranged, and the lower ends of the rods are mounted on the rotating disc.

[0006] By adopting the above technical solution, the rotating disk is driven by a drive motor to rotate at intervals, allowing different rods on the rotating disk to rotate sequentially to different work positions, realizing multi-rod step-by-step operation, adapting to dual-work position reciprocating motion, and improving the multi-rod processing capacity of the cutting machine. At the same time, the rods are set vertically and their lower ends are fixed to the rotating disk, ensuring the stability of the rods during rotation. This provides a structural basis for the subsequent precise placement of springs and cutting heads, avoiding placement deviations caused by rod swaying, indirectly improving the neatness of the cutting heads before coating, and thus ensuring the efficiency of the coating furnace in accommodating the cutting heads.

[0007] Optionally, a square rod is provided on the output shaft of the drive motor, and a receiving platform is provided on the lower end face of the square rod. An insertion hole is provided on the rotating disk, the insertion hole is used to insert into the square rod, and the receiving platform is used to abut against the lower end face of the rotating disk.

[0008] By adopting the above technical solution, the square rod can effectively transmit torque compared to the round shaft, avoiding relative slippage between the drive motor output shaft and the rotating disk, ensuring that the rotating disk can accurately follow the drive motor to achieve interval rotation, and ensuring the rhythm stability of multi-rod step-by-step operation; while the receiving platform abuts against the lower end face of the rotating disk, providing vertical support for the rotating disk, balancing the weight of the rotating disk and the rods, preventing the square rod from becoming loose due to the rotating disk shifting downwards under its own weight, and reducing the radial sway when the rotating disk rotates, further improving the overall structural stability and reducing the impact of structural offset on the placement accuracy of springs and cutter heads.

[0009] Optionally, a guide slope is provided at the end of the square rod away from the receiving platform.

[0010] By adopting the above technical solution, the guide slope can play a guiding role in the assembly process of the rotating disk and the square rod. Preliminary positioning can be achieved without precise alignment of the square rod and the insertion hole, which reduces the alignment difficulty during assembly, reduces the manual adjustment time, improves the assembly efficiency of the rod-connecting disk, and avoids damage to the square rod or insertion hole that may be caused by forced alignment, extends the service life of the components, and ensures the smooth progress of subsequent tool-connecting operations.

[0011] Optionally, the rotating disk is provided with a limiting component to prevent the square rod from detaching. A limiting ring groove is formed on the side wall of the square rod. The limiting component includes two limiting strips and two limiting springs. The length direction of the limiting strips is parallel to the radial direction of the rotating disk. The limiting strips slide along the length direction of the limiting strips. A snap-fit ​​groove is formed on the limiting strips. The snap-fit ​​groove is used to snap into the limiting ring groove. The two limiting strips are circumferentially distributed along the axis of the rotating disk. The two limiting springs correspond to the two limiting strips. The limiting springs are used to snap into the limiting ring groove.

[0012] By adopting the above technical solution, the limiting strip is pushed to slide by the elastic force of the limiting spring, so that the locking groove is stably locked onto the limiting ring groove of the square rod, forming an axial limit on the rotating disk. This effectively prevents the rotating disk from detaching from the square rod due to vibration or other external forces during operation, ensuring the connection stability of the overall structure of the stringing rod disk, avoiding equipment downtime or component damage caused by the rotating disk detaching, and ensuring that the stringing rod always maintains a stable position during rotation, without affecting the normal placement of the spring and the cutter head, maintaining the continuity and safety of the stringing operation.

[0013] Optionally, the rotating disk has a cavity, the limiting strip and the spring are both located in the cavity, the limiting strip is provided with a handle, and the handle protrudes from the rotating disk.

[0014] By adopting the above technical solution, the cavity can isolate the limiting strip and limiting spring from the external environment, preventing dust, oil and other impurities from adhering to the limiting strip and limiting spring, preventing the components from jamming or rusting due to contamination, extending the service life of the limiting components, and ensuring the stable performance of their limiting function. The handle exposed on the rotating plate allows the operator to manually pull the limiting strip, making it easy to release the limiting function when the rotating plate needs to be disassembled or maintained, without the need for additional tools, improving the convenience of operation, reducing the difficulty and time cost of equipment maintenance, and ensuring that the knife-stringing machine can be quickly restored to operation when maintenance is required.

[0015] Optionally, the frame is provided with a thrust ball bearing for abutting against the bottom wall of the rotating disk.

[0016] By adopting the above technical solution, the thrust ball bearing can convert the sliding friction between the rotating disk and the frame into rolling friction, which greatly reduces the friction force when the rotating disk rotates, making the interval rotation of the rotating disk smoother, reducing the load on the drive motor, reducing the energy consumption and wear of the motor, and extending the service life of the drive motor. At the same time, the reduced friction also avoids the wear caused by long-term friction between the bottom wall of the rotating disk and the frame, ensuring the flatness of the rotating disk, preventing the eccentricity of the rotating disk during rotation due to wear, further improving the stability of the rod position, and ensuring the accuracy of the placement of the spring and the cutter head.

[0017] Optionally, the rotating disk has several through holes, which correspond to the connecting rod. A nut is provided at the bottom of the rotating disk, and the bottom end of the connecting rod passes through the through holes and is threaded onto the nut.

[0018] By adopting the above technical solution, the threaded connection enables a detachable connection between the guide rod and the rotating disk. When the guide rod is worn, damaged, or needs to be replaced with a guide rod of different length or diameter according to different specifications of the cutter head, the guide rod can be disassembled and replaced simply by unscrewing the nut. There is no need to replace the entire rotating disk or guide rod disk structure, which reduces equipment maintenance costs, improves the adaptability of the equipment to the operation of guide rods of different specifications, meets the needs of diversified tool production in the manufacturing industry, and at the same time, the threaded connection can also ensure the firmness of the connection between the guide rod and the rotating disk, and prevent the guide rod from loosening during operation.

[0019] Optionally, the rod is provided with an abutment piece, which abuts against the upper end face of the rotating disk.

[0020] By adopting the above technical solution, the contact fit between the abutting plate and the upper end face of the rotating disk plays an axial positioning role for the string rod, restricting the displacement of the string rod in the vertical direction, preventing the string rod from moving downward due to its own weight or the pressure when placing the spring and the cutter head, ensuring that the string rod always stays at the preset height position, providing a stable benchmark for the precise placement of the spring and the cutter head, preventing inconsistent spacing between adjacent cutter heads or springs due to the height deviation of the string rod, further improving the neatness of the connected cutter heads, ensuring that the coating furnace can accommodate more cutter heads, and meeting the need in the background technology to increase the number of cutter heads that the coating furnace can accommodate.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The drive motor drives the rotating disk to rotate at intervals. Combined with several rods vertically set on the rotating disk, different rods can rotate sequentially to the spring placement position and the cutter head placement position. This breaks the limitation of single rod operation, accurately matches the needs of dual-station reciprocating motion, realizes multi-rod step-by-step operation, improves the processing capacity of the cutter head machine for multiple rods, and provides structural support for efficient connection before subsequent cutter head coating. 2. The square rod on the output shaft of the drive motor mates with the insertion hole on the rotating disk to prevent slippage between the drive motor and the rotating disk. The receiving platform at the lower end of the square rod abuts against the lower end face of the rotating disk to provide vertical support for the rotating disk. The thrust ball bearing on the frame abuts against the bottom wall of the rotating disk to reduce friction when the rotating disk rotates and maintain the smooth rotation of the rotating disk. The abutting piece on the connecting rod abuts against the upper end face of the rotating disk to limit the vertical displacement of the connecting rod. 3. The limiting components effectively prevent the rotating disk from detaching from the square rod due to vibration or other external forces, ensuring the connection stability of the overall structure of the rod tray and avoiding equipment shutdown or component damage caused by the rotating disk detaching. At the same time, it ensures that the rod remains in a stable position during rotation, without affecting the normal placement of the spring and the cutter head. Attached Figure Description
