Description

Technical Field

[0001] This invention relates to the field of gear assembly technology, and in particular to an actuator gear positioning pin guided assembly mechanism. Background Technology

[0002] A gear is a mechanical component with teeth on its rim that can continuously mesh to transmit motion and power. Gears have been used in transmission for a long time. In the late 19th century, with the emergence of the generating gear cutting method and specialized machine tools and cutting tools using this principle, the smoothness of gear operation became increasingly important as production developed.

[0003] Because gears require two gears to mesh in a gap position during assembly, most existing equipment uses two CCD vision imaging systems to photograph the two gears to be installed, determining the notch position for meshing before assembling. This technology becomes unusable when a single gear needs to mesh with two gears simultaneously, and the high cost of two CCD vision systems has resulted in gear assembly being rarely used.

[0004] For the reasons mentioned above, it is necessary to improve the existing technology. Summary of the Invention

Detailed Implementation

[0028] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0029] Please see Figure 1-7 The present invention provides an actuator gear positioning pin guiding assembly mechanism, including a frame body 1, on which a circumferentially operable robotic arm 10 is provided;

[0030] Drive device 2, which is mounted on the robotic arm 10;

[0031] Gear assembly device 3, one end of which is fixedly mounted on the drive device 2 and driven by the drive device 2 to rotate or move up and down, the gear assembly device 3 includes a mechanism body 30, a detection device 34 mounted on the mechanism body 30, a gear shaft 31 that can float up and down in the internal cavity of the mechanism body 30, and a vacuum suction mechanism 32 mounted on the mechanism body 30, wherein a gear shaft core 33 is movably mounted in the gear shaft 31;

[0032] Oiling device 4 is disposed on one side of gear assembly device 3.

[0033] In the above structure, when workers need to assemble gears, the robotic arm moves the gear assembly device above the gear, and then the gear is positioned by the gear shaft core to ensure the gear centering. At the same time, the vacuum suction mechanism is activated to vacuum the gear to the gear shaft. The robotic arm moves the gear assembly device to the oiling device position to apply oil to the gear. After the gear shaft floats up and down, the detection device and the drive device ensure that the gear meshes with the gear at the target position during the rotation and descent. This saves labor costs and can handle situations requiring multi-stage meshing.

[0034] Specifically, the drive device 2 is provided with a rotating shaft 20 at one end, and the rotating shaft 20 is fixedly connected to the gear assembly device 3. Using a rotating shaft to connect the drive device and the gear assembly device can ensure the rotational stability of the drive device when it rotates, thereby saving energy loss.

[0035] Specifically, the main body 30 of the mechanism has two vertically symmetrically positioned limiting protrusions 300, and the gear shaft 31 has a limiting recess 310 that cooperates with the limiting protrusions 300. The cooperation between the limiting protrusions and the limiting recess can ensure that the displacement of the gear shaft is vertical when it floats up and down, and ensure that the gear shaft will not float obliquely and thus get stuck.

[0036] Specifically, a first return spring 35 is provided at the top end of the gear shaft 31. The first return spring ensures that the gear shaft is reset when it is not subjected to an upward floating force.

[0037] Specifically, the gear shaft 31 includes an upper shaft portion 311 and a lower shaft portion 312 fixed to the upper shaft portion 311. The upper shaft portion 311 includes a first inner cavity 3110, and the lower shaft portion 312 includes a second inner cavity 3120. The first inner cavity 3110 and the second inner cavity 3120 are positioned correspondingly, and the diameter of the first inner cavity 3110 is larger than that of the second inner cavity 3120. The gear shaft core 33 in the first inner cavity 3110 is provided with a protrusion 330, and the side of the protrusion 330 abuts against the first inner cavity 3110. A second return spring 331 is provided at the upper end of the protrusion 330. The protrusion is used to lock the gear shaft core in the first inner cavity, which restricts the up and down floating position of the gear shaft core. At the same time, the second return spring is provided on the upper side of the protrusion to ensure that when the gear shaft core is no longer subjected to the upward floating force, the second return spring resets and drives the gear shaft core to reset.

[0038] Specifically, the detection device 34 is a displacement sensor. The displacement sensor detects the rotation of the gear shaft. When the gear assembly device descends to the gear assembly position, the displacement sensor detects that the gear shaft rotates normally, thus indicating successful gear meshing. When the gear assembly device descends to the gear assembly position, the displacement sensor detects that the gear shaft rotates abnormally, thus indicating that gear meshing has failed. Using a displacement sensor has advantages such as high reliability, high accuracy, simple installation and maintenance, and ease of systematization.

[0039] Specifically, the oiling device 4 is equipped with an oil weighing device 40. The gear assembly device picks up the gear and moves it to the position of the oiling device to rotate and apply oil. The oil weighing device below catches the oil dripping after the gear is finished applying oil, and the amount of oil sprayed is ensured by weighing.

[0040] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
