DETAILED DESCRIPTION

[0028] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] See also Figure 1 to Figure 9As shown, an electric cylinder driven bearing installation mechanism and a back-power gearbox bearing assembly device include a body 1, a rotating chuck 2 for clamping a bearing, a sliding seat 3 for mounting the rotating chuck 2 and a first linear driver 4 for driving the sliding seat 3 to slide horizontally, and a rotating installation mechanism 5 for automatically installing a ball bearing on the clamped bearing on the rotating chuck 2. The rotating installation mechanism 5 includes a first barrel 51 and a first rotating driver 52 for driving the first barrel 51 to rotate. The bearing installation mechanism also includes an adjustment mechanism 6 for adjusting the position of the rotating installation mechanism 5. The first rotating The driver 52 is arranged on the machine body 1. The output end of the first rotary driver 52 is connected to a rotating rod through a coupling. The rotating rod is coaxially fixed to the first barrel 51. A plurality of clearance grooves for the balls to pass through are provided at the bottom of the first barrel 51. The output end of the first linear driver 4 is connected to a threaded rod through a coupling. The threaded rod is threadedly connected to the sliding seat 3 to drive the sliding seat 3 to move horizontally. The top of the first barrel 51 is an open shape for placing the balls in the first barrel 51. A limiting rod for limiting the displacement of the inner ring of the bearing is provided on the rotary chuck 2.

[0030] First, the outer ring and inner ring of the bearing to be assembled are placed on the rotating chuck 2, and then the first linear drive 4 is started to drive the threaded sliding seat 3 to move horizontally and linearly. After the balls are placed in the first barrel 51, the position of the first barrel 51 is moved to the rotating chuck 2 through the adjustment mechanism 6, and then the balls in the first barrel 51 are automatically and evenly dropped onto the bearing to be assembled, thereby improving the assembly and installation efficiency of the bearings.

[0031] See also Figure 3 and Figure 5 As shown, the rotating installation mechanism 5 also includes a second barrel 53 and a second rotating driver 54; the second barrel 53 is arranged outside the first barrel 51 and below the first rotating driver 52; the second rotating driver 54 is arranged on the body 1 and close to one side of the first rotating driver 52, and an escape groove for the balls to fall is provided at the bottom of the second barrel 53, and there are four escape grooves in an array along the bottom circumference of the second barrel 53. The arrangement of the four escape grooves enables the balls to smoothly roll onto the rotating chuck 2 and then be located above the bearing, and a bearing is connected between the upper end of the second barrel 53 and the first barrel 51, with a cylinder with an arc that limits the balls from moving to the position of the escape groove provided on the second barrel 53, and the second barrel 53 is arranged outside the first barrel 51 and is rotatably connected to the first barrel 51 through the cylinder.

[0032] The balls are first placed in the first barrel 51, and then the first rotary driver 52 is started, driving the first barrel 51 to rotate through the transmission rod. At this time, the balls placed in the first barrel 51 roll down through the clearance grooves provided on the first barrel 51 until the balls fall into the second barrel 53.

[0033] See also Figure 3 and Figure 5 As shown, the rotating mounting mechanism 5 also includes a first gear 55 and a first gear ring 56; the first gear 55 is arranged on the output shaft of the second rotating driver 54; the first gear ring 56 is arranged on the outside of the second barrel 53 and meshes with the first gear 55, and the output shaft of the second rotating driver 54 is connected to a circular rod through a coupling, and the circular rod is coaxially fixed with the first gear 55.

[0034] When the balls in the second barrel 53 are rotating and falling evenly, the second rotary driver 54 is started, causing the first gear 55 provided on the outside of the circular rod to rotate. When the first gear 55 rotates, the meshing first gear ring 56 can be rotated. At this time, the second barrel 53 coaxially fixed with the first gear ring 56 can rotate in the opposite direction or in the same direction as the first barrel 51, so that the balls in the second barrel 53 can be evenly dropped onto the bearing through the avoidance groove provided on the second barrel 53, so as to improve the installation speed and efficiency of the balls.

[0035] See also Figure 5 and Figure 6 As shown, the adjustment mechanism 6 includes a second linear drive 61 and a first sliding plate 62; the second linear drive 61 is arranged on the body 1 and is located above the first rotation drive 52; the first sliding plate 62 is slidably arranged on the top of the first rotation drive 52, and the output end of the second linear drive 61 is connected to a screw rod through a coupling, and the screw rod is threadedly connected to the first sliding plate 62, the first rotation drive 52 is installed on the sliding plate, and a limiting groove for limiting the vertical sliding of the first sliding plate 62 is provided on the body 1.

[0036] When the rotating mounting mechanism 5 needs to be moved downward, the second linear drive 61 can move the threaded first sliding plate 62 downward. When the first sliding plate 62 moves, it can slide smoothly in the vertical direction on the body 1, thereby achieving the adjustment of the vertical position of the rotating mounting mechanism 5 set on the first sliding plate 62.

[0037] See also Figure 6 and Figure 7As shown, the adjustment mechanism 6 also includes a limiting plate 63; the limiting plate 63 is arranged on the first sliding plate 62, and the first sliding plate 62 is fixedly connected to the limiting plate 63. A limiting block is arranged on the body 1 for limiting the sliding of the plate 63 in the vertical direction. The limiting block is provided with a stroke groove for the horizontal linear sliding of the rotating mounting mechanism 5. The stroke block is slidingly arranged on the limiting block, and the stroke block is provided with a limiting groove for limiting the horizontal sliding of the limiting block. A frame is installed on the body 1, and the frame is fixedly installed on the first sliding plate 62 and is located above the rotating chuck 2. An electric cylinder for driving the rotating mounting mechanism 5 to slide horizontally along the stroke block is arranged below the frame. The electric cylinder is used to control the rotating mounting mechanism 5 to move to just above the rotating chuck 2, so as to facilitate the falling positioning of the ball of the rotating mounting mechanism 5.

[0038] When adjusting the position of the rotating mounting mechanism 5, the second linear drive 61 is started, causing the threaded first sliding plate 62 to move downward, which facilitates the downward position adjustment of the rotating mounting mechanism 5, and then the electric cylinder is started again to drive the rotating mounting mechanism 5 to slide horizontally along the stroke groove, so that the rotating mounting mechanism 5 can be better aligned with the position of the rotating chuck 2, so that the ball can fall into the bearing better and more accurately.

[0039] See also Figure 6 and Figure 7 As shown, the bearing installation mechanism also includes a clamping mechanism 7 for picking up and placing the bearing on the rotating chuck 2; the clamping mechanism 7 includes a positioning column 71, a second gear 72 and a swing arm 73; the positioning column 71 is arranged on the body 1 and close to one side of the rotating chuck 2; the second gear 72 is rotatably arranged on the body 1; the swing arm 73 is rotatably arranged on the outside of the positioning column 71 and is coaxially fixed with the positioning column 71, and a third rotating driver connected to the second gear 72 is arranged on the body 1, and the third rotating driver is used to drive the second gear 72 to rotate.

[0040] In the working state, the swing arm 73 can be moved to the rotating chuck 2 by rotating along the positioning column 71, and then the bearing installed on the rotating chuck 2 can be taken.

[0041] See also Figure 1 and Fig. 9 As shown, the bearing mounting mechanism also includes a second gear ring 74 and a clamping cylinder 75; the second gear ring 74 is arranged on the outer wall of the positioning column 71 and meshes with the second gear 72; the clamping cylinder 75 is arranged below the end of the swing arm 73 away from the positioning column 71, and the second gear ring 74 is coaxially fixed with the positioning column 71. When the third rotary driver rotates, the second gear 72 can be driven to rotate the meshed second gear ring 74 and drive the positioning column 71 to rotate at an angle of inclination.

[0042] When it is necessary to take the processed bearing on the rotating chuck 2, the second gear 72 rotates to cause the second gear ring 74 to rotate. When the second gear ring 74 rotates, it can drive the positioning column 71 and the swing arm 73 to rotate, causing the swing arm 73 to move to the top of the chuck 72, and then start the clamping cylinder 75, so that the bearing on the rotating chuck 2 can be clamped and taken, which reduces manual participation and reduces the risk of the bearing falling to the ground due to manual operation errors.

[0043] The utility model also provides a back-power gearbox bearing assembly device, which comprises the above-mentioned electric cylinder driven bearing installation mechanism.
