Embodiment 1

[0053] like figure 1 and figure 2 Shown is the structure of the mowing hob, which mainly includes a hob shaft 1, a cutter head 2 and a hob blade 4; among them, there are multiple cutter heads 2 welded at equal intervals along the axial direction of the hob shaft 1, and the cutter head There are slots 5 along the circumferential direction on the 2, and the spiral hob blades 4 are inserted into these slots 5 in sequence for positioning, and then welded and fixed, and corresponding to the number of slots 5, generally a circle of uniform slots in the circumferential direction is set on the cutter head 2. The positioning hole 3 of the cloth is used for adjusting the dynamic balance of its rotation after hob processing. In addition, there is a bearing segment 6 at both ends of the hob shaft 1, which is used to install the bearings, so that the hob is installed on the lawn machine when in use. In addition, the outer surface of the hob blade 4 has a blade, and the blade is two slop...

Embodiment 2

[0060] This embodiment provides a welding method for a grass mowing hob. The robot welding device for the grass mowing hob in Embodiment 1 is used in cooperation with a welding robot to weld the hob blade 4 to the cutter head 2 . In this embodiment, there are 5 cutterheads 2 and 10 hob blades 4. Generally, the back angle α=16° and the edge angle β=53°. The specific operation steps of welding are as follows:

[0061] ①Install the hob 4 into the slot 5 on the cutter head 2 in sequence, and fix it from both ends and / or the middle of the hob 4 through a packing steel belt or hoop. Here, the hoop is selected from the hob 4 Fixed at both ends;

[0062] ②Place the hob on the supporting plate 430 of the material supporting mechanism 400, and the supporting cylinder 420 works to adjust the height of the supporting plate 430, so that the hob shaft 1 of the hob is coaxial with the first thimble 220, and the first thimble 220 pushes into the thimble hole at one end of the hob shaft 1;

...

Embodiment 3

[0068] This embodiment provides a grinding method of a grass mowing hob. The hob welded in Embodiment 1 is ground to grind the cutting edge of the hob blade 4 . And the hob blade 4 itself is helical, and its blade is also helical, and the grinding along the helical line cannot be accomplished by present common grinders, and is also the difficult point of hob grinding. The utility model relates to a blade grinding device of a mowing hob, which is used to grind the blade of a hob 4.

[0069] like Image 6 and Figure 7As shown, the blade grinding device of the mowing hob in this embodiment includes a grinding wheel mechanism, and the grinding wheel mechanism includes a fixed support assembly 500 , a movable support assembly 600 and a grinding wheel assembly 700 . Wherein, the fixed support assembly 500 includes a fixed support 510 and a first support plate 520 installed on the fixed support 510, the first support plate 520 has a first bearing hole; Support 610, second support...

Abstract

The invention discloses a grass cutting hob blade grinding device and a grinding method thereof, and belongs to the field of lawn mechanical tool machining. The device comprises a grinding wheel mechanism. The grinding wheel mechanism comprises a fixed supporting assembly, a movable supporting assembly and a grinding wheel assembly. The fixed supporting assembly comprises a fixed support and a first supporting plate mounted on the fixed support. The first supporting plate is provided with a first bearing hole. The movable supporting assembly comprises a movable support slidably arranged on a guide rail, a second supporting plate and a motor. The second supporting plate is mounted on the movable support and provided with a second bearing hole. The motor is connected with the movable supportthrough a screw-nut pair. The grinding wheel mechanism comprises a grinding wheel base, a grinding wheel and a follow-up pressing plate. The grinding wheel and the follow-up pressing plate are mounted on the grinding wheel base. The follow-up pressing plate is located under the grinding wheel. The grinding wheel is driven by a grinding wheel motor. The device is simple and ingenious in structureand can grind spiral hob blades.

Description

technical field [0001] The invention belongs to the field of lawn machine tool processing, and more specifically relates to a blade grinding device and a grinding method of a grass mowing hob. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the greening level of living and living, and the large-scale ecological green spaces, residential green spaces, and road green spaces in cities are constantly increasing. Lawn mowers (also known as mowers and lawn mowers) are popular among users because of their light weight, small size, and flexible operation. [0003] The principle of cutting the lawn mower is to roll up the grass by the hob, and the blades on the hob cut off the weeds. The hob of the lawn mower includes a hob shaft, a cutter head, and a hob blade. The hob assembly sequence is to first put multiple cutter heads on the hob shaft at intervals, and weld them to fix them, and then insert the hob blades ...
