[0017] 3. Beneficial effects

[0018] Compared with the existing known technology, the technical solution provided by the present invention has the following beneficial effects:

[0019] (1) The present invention relates to an automatic polishing machine for inner hole walls of rods. Rods in a material bin fall onto an automatic rod feeding mechanism through a vertical channel under the action of gravity. The automatic rod feeding mechanism feeds the rods one by one onto a rod rotating support mechanism. The rod rotating drive mechanism drives the rods on the rod rotating support mechanism to rotate. The polishing mechanism polishes the inner hole walls of the rods. The machine has a simple structure and is easy to operate. The whole process is automated, saving time and effort. The inner hole walls of the rods are polished evenly with good polishing quality.

[0020] (2) An automatic polishing machine for the inner hole wall of a rod member of the present invention has a rod member rotation support mechanism with a simple structure and convenient connection. The two ends of the rod member are respectively supported on the left roller and the right roller, which is convenient for supporting and rotating the rod member. A discharge port for discharging the processed rod member is provided on the workbench of the support and between the two roller support longitudinal plates. One of the two roller support longitudinal plates is fixedly arranged on the workbench of the support, and the other roller support longitudinal plate is connected to the workbench of the support through a first slider rail mechanism. The other roller support longitudinal plate is driven to move by a first forward and backward moving driver to carry the rod member or release the rod member. When it is necessary to carry the rod member, the first forward and backward moving driver controls the roller support longitudinal plate to move forward, so that the two roller support longitudinal plates are clamped. The left end of the rod member is supported on the two left rollers, and the right end of the rod member is supported on the two right rollers. When it is necessary to release the rod member, the first forward and backward moving driver controls the roller support longitudinal plate to move backward, so that the two roller support longitudinal plates are separated, and the rod member falls from the discharge port.

[0021] (3) The present invention is an automatic polishing machine for inner hole wall of a rod, and its rod rotation driving mechanism has a simple structure and is convenient to connect. The second forward and backward moving driver controls the driving wheel to act on or not act on the rod, and the driving wheel is driven to rotate by the rotating driver, thereby driving the rod to rotate;

[0022] (4) The present invention provides an automatic polishing machine for the inner hole wall of a rod, the polishing mechanism of which has a simple structure and is convenient to connect. The position of the electric polishing tool is adjusted by the first left-right moving driver and the third front-back moving driver, thereby achieving the purpose of polishing the inner hole wall of the rod;

[0023] (5) An automatic polishing machine for the inner hole wall of a rod member of the present invention has an automatic rod loading mechanism with a simple structure and convenient connection. The rod members in the bin fall into the pushing port of the pushing plate through the vertical channel under the action of gravity and are placed on the carrying plate. The pushing plate is controlled to move forward by the fourth forward and backward moving driver. Under the action of the pushing port, the rod members on the carrying plate are pushed forward. At this time, the rod members fall from the unloading port to the rod member rotating support mechanism, and the pushing plate blocks the outlet of the vertical channel. After the rod member loading is completed, the pushing plate is controlled to move backward by the fourth forward and backward moving driver. At this time, the pushing port is directly opposite to the outlet of the vertical channel. Under the action of gravity, the rod members fall into the pushing port from the vertical channel and are placed on the carrying plate. The above-mentioned steps are cyclically operated to achieve the purpose of loading the rod members in the bin onto the rod member rotating support mechanism one by one. Since a baffle is provided on the loading plate close to the front side of the unloading port, it is further ensured that the rod members are unloaded from the unloading port.

[0024] (6) The automatic polishing machine for inner hole wall of a rod of the present invention, its automatic feeding mechanism for rods also includes a rod falling driving mechanism for driving the rods in the hopper to smoothly fall to the vertical channel, which has a simple structure and is convenient to connect. When the fourth forward and backward moving driver controls the push plate to move forward so that a rod falls from the discharge port, the top block moves upward under the action of the inclined surface of the block, and the rod in the hopper is pushed upward. When the fourth forward and backward moving driver controls the push plate to move backward so that a rod is discharged to the push port, the top block moves downward under the action of the inclined surface of the block, and the lifted rod falls. By pushing the rods in the hopper up and down, the rods in the hopper fall more smoothly from the discharge port.

[0025] (7) The present invention is an automatic polishing machine for the inner hole wall of a rod, wherein the front side surface and the left and right side surfaces of the hopper are vertical surfaces perpendicular to the workbench of the support, and the lower part of the rear side surface of the hopper is an inclined surface inclined with the workbench of the support. The structure is simple and the design is ingenious, which is conducive to the rod in the hopper falling from the discharge port. The hopper is divided into a left half hopper and a right half hopper. The left half hopper and the right half hopper are connected by a spacing adjustment mechanism that can adjust the spacing according to the length of the rod, and the lengths of the corresponding feed port, push port and discharge port are all greater than or equal to the maximum spacing that can be adjusted by the spacing adjustment mechanism. The rod falling driving mechanism is located between the left half hopper and the right half hopper. The rod falling driving mechanism changes its installation position as the spacing between the left half hopper and the right half hopper changes. The distance between the right roller mounting plate and the left roller mounting plate changes as the spacing between the left half hopper and the right half hopper changes. The hopper can change its size according to the length of the rod and can adapt to the placement of rods of different sizes. The automatic polishing machine can polish rods of different sizes and is more flexible to use.

[0026] (8) The automatic polishing machine for the inner hole wall of a rod member of the present invention has a simple spacing adjustment mechanism structure, convenient connection, and easy operation. When the spacing between the left half silo and the right half silo needs to be adjusted, it is only necessary to adjust the fixed position of the silo support column along the first adjustment slide groove.
