Description
Technical Field
[0001] The utility model relates to the technical field of lawn mowers, in particular to a lawn mower head assembly. Background Art
[0002] At present, the trend of mechanical automation is becoming increasingly obvious. In the production process of a part of equipment, it is usually necessary to assemble the various parts of the production equipment together. The assembly task of the equipment can be completed in the form of an assembly line. However, in the process of assembly line, the use of automatic clamps is indispensable, and in order to facilitate assembly, the clamps often need to be rotated to a specified angle. The assembly line of the lawn mower head cannot do without the use of automatic clamps.
[0003] However, the rotating assembly structure of the existing lawn mower head clamp is too simple, and the rotation of the clamp is controlled only by the rotating shaft of the rotating assembly, resulting in poor stability when the clamp rotates, which can easily cause the clamp to shake, causing the lawn mower head clamped in the clamp to loosen, affecting the assembly of the lawn mower head. Secondly, the existing clamps are mostly installed and fixed by bolts, which makes it time-consuming and laborious to disassemble the clamp later, affecting the work efficiency of the assembly line. In view of the above problems, the inventor proposes a lawn mower head assembly to solve the above problems. Utility Model Content
[0004] In order to solve the problem that the rotating assembly structure of the existing lawn mower head clamp is too simple, and the rotation of the clamp is controlled only by the rotating shaft of the rotating assembly, resulting in poor stability when the clamp rotates, which easily causes the clamp to shake, causing the lawn mower head clamped in the clamp to loosen, affecting the assembly of the lawn mower head; the purpose of the utility model is to provide a lawn mower head assembly.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a lawn mower head assembly, including a fixing seat, a fixing seat is fixedly installed in the middle of the top surface of the fixing seat, a motor is installed in the fixing seat, a rotating shaft is fixedly installed at the output end of the motor, a mounting platform is fixedly installed at the top of the rotating shaft, an automatic clamp is detachably installed on the top surface of the mounting platform, evenly distributed stabilizing bars are fixedly installed on the bottom surface of the mounting platform, the number of stabilizing bars is three, and rollers are fixedly installed at the bottom ends of the three stabilizing bars, a fixing frame is fixedly installed on the top surface of the fixing seat, a fixing ring is fixedly installed in the top surface of the fixing frame, a rotating groove is opened on the top surface of the fixing ring, and the roller is rotatably installed in the rotating groove;
[0006] The device is installed on the assembly line for installing the lawn mower head and fixed, and the lawn mower head to be assembled is clamped by the automatic clamp. When the lawn mower head clamped in the automatic clamp needs to be rotated to adjust the angle, the switch of the motor in the mounting seat is turned on, and the rotating shaft is controlled to rotate by the output end of the motor. When the rotating shaft rotates, the mounting platform is driven to rotate, and the lawn mower head clamped in the automatic clamp is controlled to rotate by the mounting platform, and the lawn mower head is stopped when it rotates to a specified angle, and the fixing ring is installed and fixed by the fixing frame. When the mounting platform rotates, the three rollers installed at the bottom ends of the three stabilizing bars installed on the bottom surface of the mounting platform follow the mounting platform to rotate in the rotating grooves provided in the fixing ring. With the cooperation of the three rollers, the stability of the mounting platform and the automatic clamp is increased during rotation, and the existing automatic clamp is prevented from being rotated only by the rotating shaft when the automatic clamp is rotated and adjusted, and the stability is poor, which easily causes the automatic clamp to shake, resulting in the loosening of the lawn mower head clamped in the automatic clamp, affecting the assembly of the lawn mower head.

The positioning component and the automatic clamp cooperate with each other, and the positioning pin of the positioning component is inserted into the bottom surface of the automatic clamp to complete the limited fixation of the automatic clamp on the mounting table. When the automatic clamp needs to be disassembled, the positioning pin is taken out from the automatic clamp through the reset spring, and the automatic clamp can be removed from the mounting table. The cooperation between the positioning component and the mounting table facilitates the disassembly and assembly of the automatic clamp, which solves the problem of the existing automatic clamp being installed and fixed by bolts, resulting in inconvenience in disassembly and assembly, time-consuming and labor-intensive, and affecting the work efficiency of the assembly line.

The damping strips are damped and inserted in the damping grooves. The damping strips and the damping grooves cooperate with each other. The two damping strips installed on the bottom surface of the automatic clamp are inserted in the two damping grooves. For the limitation of the automatic clamp, a push-pull buckle is fixedly installed on one side of the surface of the sliding part. The push-pull buckle is slidably installed on one side of the surface of the mounting table. The push-pull buckle and the sliding part cooperate with each other. The sliding part is controlled by the push-pull buckle to drive the positioning pin to be inserted and removed in one side of the bottom surface of the automatic clamp to complete the disassembly and assembly of the automatic clamp.
[0009] Preferably, a bearing is sleeved on one end of the surface of the rotating shaft, and the bearing is fixedly installed in the top surface of the mounting seat. The bearing and the rotating shaft cooperate with each other, and the rotating shaft is assisted by the bearing to rotate, thereby increasing the stability of the rotating shaft during rotation. A groove body is opened in the mounting seat, and the motor is fixedly installed in the groove body. The motor is installed and fixed through the groove body in the mounting seat, thereby controlling the mounting table to drive the automatic clamp to rotate.

[0033] Working principle: The device is installed on the assembly line for installing the mower head and fixed. The mower head to be assembled is clamped by the automatic clamp 6. When the mower head clamped in the automatic clamp 6 needs to be rotated to adjust the angle, the switch of the motor 21 in the mounting seat 2 is turned on, and the rotating shaft 22 is controlled to rotate through the output end of the motor 21.
