Description

Technical Field

[0001] This utility model relates to the field of electric drill gearbox assembly technology, specifically to a planetary gear assembly mechanism. Background Technology

[0002] The planetary gear assembly in the electric drill gearbox is the core transmission unit for achieving power reduction and torque amplification. It is usually composed of a sun gear, planet gears (3 to 5 evenly distributed), an internal gear ring, and a planetary frame. The quality of this process has a decisive impact on the stability of the electric drill's output torque and its no-load speed.

[0003] The industry generally uses manual pressing and assembly, but the following shortcomings still exist in the assembly process: Large deviation in the press-fitting of the shaft pin and misalignment of the teeth meshing; Each process is time-consuming, extremely labor-intensive, and requires a long training period for personnel. The concentrated impact force during manual hammering causes plastic deformation at the edge of the planetary gear bearing hole, posing a risk of scratching the tooth surface; Therefore, a planetary gear assembly mechanism is needed to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a planetary gear assembly mechanism to solve the problems mentioned in the background art, which are that the industry generally uses manual pressing and assembly, and the assembly still has problems such as low assembly accuracy, deterioration of transmission performance, low production efficiency, high labor costs, high parts damage rate, and serious material waste.

In addition, a first magnetic chuck, a second magnetic chuck, and a third magnetic chuck are respectively located above the planetary gear fixture, the sun carrier fixture, and the internal gear ring fixture, and the first magnetic chuck, the second magnetic chuck, and the third magnetic chuck move horizontally and vertically to install and transport accessories of adjacent fixtures.

[0006] To achieve the above technical solution, the first magnetic chuck, the second magnetic chuck, and the third magnetic chuck are used to install and transport the various components of the gear in sequence, thereby quickly completing the installation of the planetary gear set. Compared with the existing technology, the operation process of this device is faster, the overall efficiency is higher, and the overall assembly is less prone to errors and has better stability.

[0007] As a further improvement to this utility model, the planetary gear tooling is rotatably connected on the assembly frame and driven by a servo motor. The planetary gear tooling has several centrally symmetrical slots for the planetary gears to be inserted.

[0008] To achieve the above technical solution, the planetary gears are rotated to move into their corresponding slots, thus completing the planetary gear positioning.

[0009] As a further improvement to this utility model, a height sensing component is also connected to the first magnetic holder.

[0010] The above technical solution ensures the stability of the planetary gear installation.

[0011] As a further improvement to this utility model, the first magnetic chuck, the second magnetic chuck, and the third magnetic chuck are connected to the same moving component on the track located on the assembly frame, and the moving component reciprocates horizontally along the distribution trajectory of the planetary gear tooling, the sun frame tooling, the internal gear ring tooling, and the conveying tooling.

[0012] The above technical solution improves the synergistic effect of the first magnetic chuck, the second magnetic chuck, and the third magnetic chuck.

[0013] As a further improvement to this utility model, the assembly frame at the end of the conveying tool's stroke is also connected to a finished magnetic suction frame that can be rotated and pressed in.

[0014] The above technical solution facilitates the insertion of the finished product into the product casing.

Detailed Implementation The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] Example: Referring to the accompanying drawings, this utility model provides a planetary gear assembly mechanism, including an assembly mechanism 100. The assembly mechanism 100 includes an assembly frame 110, on which a planetary gear tooling 111, a sun frame tooling 112, an internal gear ring tooling 113, and a conveying tooling 114 are arranged in a straight line. The planetary gear tooling 111 is rotatably connected to the assembly frame 110 and driven by a servo motor. The planetary gear tooling 111 has several centrally symmetrical slots for the planetary gears to be inserted. At the end of the stroke of the conveying tooling 114, a finished magnetic suction frame 118 with a suction head that can be rotated and pressed into the assembly frame 110 is also connected. In addition, a first magnetic chuck 115, a second magnetic chuck 116, and a third magnetic chuck 117 are respectively located above the planetary gear tooling 111, the sun carrier tooling 112, and the internal gear ring tooling 113. The first magnetic chuck 115, the second magnetic chuck 116, and the third magnetic chuck 117 can move horizontally and vertically to install and transport accessories of adjacent tooling. A height sensing component is also connected to the first magnetic chuck 115. The first magnetic chuck 115, the second magnetic chuck 116, and the third magnetic chuck 117 are connected to the same moving component on the track located on the assembly frame 110, and the moving component reciprocates horizontally along the distribution trajectory of the planetary gear fixture 111, the sun frame fixture 112, the internal gear ring fixture 113, and the conveying fixture 114.

[0023] The vibratory feeder sorts and delivers the planetary gears to the planetary gear fixture 111. The planetary gear fixture 111 is positioned and checks whether the three planetary gears are in place. The cylinder of the first magnetic chuck 115 descends and the height sensor measures the value. If the value is within the limit range, the electromagnetic head of the first magnetic chuck 115 descends and attracts the positioned planetary gears. The first magnetic chuck 115 rises back to its original position. The horizontally moving workpiece on the assembly frame 110 moves, allowing the first magnetic chuck 115 to move above the sun frame fixture 112 and be translated to the planetary carrier mechanism. The sun frame fixture 112 holds the planetary carrier in the sun gear carrier. The first magnetic chuck 115 descends and installs the planetary gears into the planetary carrier. After the first magnetic chuck 115 descends, the height sensor checks the height. If the height is within the range, it indicates that the assembly is in place. After the assembly is in place, the magnetic head of the first magnetic chuck 115 releases the magnetic attraction and rises back to its original position. The horizontally moving workpiece on the assembly rack 110 is moved back to its original position, allowing the second magnetic chuck 116 to reposition above the sun frame fixture 112. The cylinder is activated to lower the second magnetic chuck 116 and use the magnetic suction head to lift the sun frame with gears. After being lifted, the horizontally moving workpiece on the assembly rack 110 is moved, allowing the second magnetic chuck 116 to move above the internal gear ring fixture 113. The cylinder is activated to lower the second magnetic chuck 116, allowing the sun frame with gears and the internal gear ring to press and assemble. After being in place, the magnetic suction head of the second magnetic chuck 116 is released and rises back to its original position. The horizontally moving workpiece on the assembly frame 110 is moved back to its original position, so that the third magnetic suction frame 117 is positioned above the internal gear ring fixture 113 again. The cylinder is activated, and the third magnetic suction frame 117 descends to pick up the internal gear ring with the gear planetary carrier. The X transport mechanism is moved to the top of the conveying fixture 114 and the finished gear set is placed on the conveying fixture 114. After the conveying fixture 114 continuously conveys the material to the picking position, the finished product magnetic suction frame 118 descends to pick up the assembled inner gear ring, moves it horizontally onto the product's conveying line, and then descends and allows the rotary cylinder to rotate back and forth to install it into the product's outer shell.
