DETAILED DESCRIPTION

[0020] The following will be combined with the attached embodiment of the present utility model Figure 1-4 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] As shown in the figure, a material unloading and stacking device for bearing production includes a frame 1, on which a stacking mechanism 2 and a material shifting mechanism 3 are arranged, the stacking mechanism 2 includes a rotating disk 21 and a stacking support rod 22, the rotating disk 21 can be horizontally rotatably arranged on the frame 1 and is transmission-connected to a first motor 23 arranged on the frame 1, a plurality of stacking support rods 22 are vertically arranged on the rotating disk 21 along a central annular array of the rotating disk 21, the material shifting mechanism 3 includes a pneumatic clamp 31, a slide cylinder 32 and a rodless cylinder 33, the rodless cylinder 33 is horizontally arranged on the frame 1 and is located on one side above the stacking support rod 22, the slide cylinder 32 is fixedly connected to the sliding seat of the rodless cylinder 33 with the output shaft facing downward, the pneumatic clamp 31 is fixedly connected to the sliding seat of the slide cylinder 32 with the clamp facing downward, and the clamp of the pneumatic clamp 31 can be aligned with the upper end of one of the stacking support rods 22.

[0022] Specifically, the rotating disk 21 is rotatably arranged on the frame 1: a support frame 24 is arranged on the frame 1, a slewing bearing 25 is arranged on the support frame 24, the rotating disk 21 is connected to the slewing bearing 25, the first motor 23 is located below the support frame 24, and the output shaft of the first motor 23 passes through the support frame 24 and the slewing bearing 25 to be connected to the rotating disk 21.

[0023] In the above embodiment, the stacking mechanism 2 can be used for the stacking operation of the outer ring or the inner ring of the bearing. The working principle is the same when applied to both. The outer ring is described in detail below. The frame 1 is set at the end of the discharge conveyor belt of the outer ring production line of the bearing. The processed outer ring is conveyed to the end of the discharge conveyor belt along the discharge conveyor belt. The rodless cylinder 33 drives the slide cylinder 32 and the pneumatic clamp 31 to move above the outer ring. The slide cylinder 32 drives the pneumatic clamp 31 to move downward, so that the pneumatic clamp 31 clamps the outer ring on the discharge conveyor belt. Then the slide cylinder 32 and the rodless cylinder 33 are reset in succession, driving the pneumatic clamp 31 to move to a position where its clamp is aligned with the upper end of one of the stacking struts 22, so that the outer ring is moved to a position where its inner hole is aligned with one of the stacking struts 22. After the slide cylinder 32 drives the pneumatic clamp 31 downward to make the outer ring sleeved on the stacking strut 22, the pneumatic clamp 31 releases its grip on the outer ring. The outer ring slides downward on the stacking support rod 22 and falls onto the rotating disk 21. By repeating the above operation, the outer rings transported by the discharge conveyor belt can be sleeved on the stacking support rod 22 one by one for stacking. When the outer ring is stacked on a stacking support rod 22 to the upper end of the stacking support rod 22, the first motor 23 drives the rotating disk 21 to rotate a certain angle, so that the next adjacent stacking support rod 22 moves to a position where it can be aligned with the jaws of the pneumatic clamp 31, and the outer ring is stacked on the next stacking support rod 22. In this way, the outer ring can be neatly stacked on each stacking support rod 22, eliminating the trouble of manual stacking, saving manpower, and improving production efficiency. When the rotating disk 21 is driven by the first motor 23 to rotate, the rotating disk 21 has a strong load-bearing capacity through the action of the slewing bearing 25, thereby ensuring the stability of the rotating disk 21 during rotation, and then ensuring the stability during unloading and stacking.

[0024] Preferably, a plurality of upright screw rods 211 are fixedly connected to the rotating disk 21, and the lower ends of the stacking struts 22 are screwed to the screw rods 211. The above structure facilitates the disassembly and assembly of the stacking struts 22, and the stacking struts 22 that match the inner hole of the outer ring can be easily replaced according to the specifications of the bearing outer ring, so that the outer ring unloading and stacking can be more neat when the stacking struts 22 are used.

[0025] Furthermore, a supporting mechanism 4 is also provided on the frame 1, and the supporting mechanism 4 includes a supporting seat 41 and a supporting plate 42. The supporting seat 41 can be longitudinally slidably arranged on the frame 1 and is transmission-connected to a second motor 43 arranged on the frame 1. The supporting plate 42 is vertically arranged on the supporting seat 41. A through hole 212 is provided on the rotating disk 21 on one side of the stacking support rod 22 for the supporting plate 42 to pass through. When the jaws of the pneumatic clamp 31 are aligned with the upper end of one of the stacking support rods 22, the supporting plate 42 can pass through the through hole 212 and be aligned with the jaws of the pneumatic clamp 31.

[0026] Specifically, the support seat 41 is slidably arranged on the frame 1: the frame 1 is provided with two upright sliding struts 44, the support seat 41 is penetrated by the sliding struts 44, and a transmission screw 45 is rotatably arranged on the frame 1, which is connected to the second motor 43 through the cooperation of the synchronous wheel and the synchronous belt and is located between the two sliding struts 44, and the transmission screw 45 is screwed into the support seat 41.

[0027] In the above preferred embodiment, when the outer ring of the bearing is stacked on the stacking support rod 22, the second motor 43 drives the transmission screw 45 to rotate, and drives the support seat 41 to slide upward on the sliding support rod 44. The support seat 41 drives the support plate 42 to pass through the through hole 212 and is located on one side of the stacking support rod 22. When the material moving mechanism 3 puts the first outer ring on the stacking support rod 22, the outer ring is placed on the upper end of the support plate 42. While the material moving mechanism 3 transfers the next outer ring, the second motor 43 drives the support plate 42 to move downward a distance consistent with the thickness of the outer ring, so that when the next outer ring is put on the stacking support rod 22, it is placed on the previous outer ring. In the above manner, the outer ring is always supported by the support plate 42 when it is stacked on the stacking support rod 22, and will not slide on the stacking support rod 22, thus avoiding The front and rear outer rings collide and are damaged when they are unloaded and stacked on the stacking support rod 22. After the unloading and stacking is completed, the frame 1 is moved to the starting side of the loading conveyor belt of the next process (which can be a cleaning process, a quenching process, etc.), and the supporting plate 42 moves upward through the through hole 212 to lift up the outer ring stacked on the stacking support rod 22 and move it upward intermittently for a distance. In conjunction with the material shifting mechanism 3, the outer ring on the stacking support rod 22 can be loaded onto the loading conveyor belt of the next process. The loading operation of the material shifting mechanism 3 is opposite to its unloading operation, which will not be repeated here, so that this unloading and stacking device can also be used as a loading device, eliminating the operation of transferring the outer ring after unloading and stacking to an additional loading device, thereby saving manpower and improving production efficiency.

[0028] Preferably, two support plates 42 are symmetrically arranged along the axis of the transmission screw 45 and the cross-section of the support plate 42 is arc-shaped. Through the above structure, the support plate 42 can better support the outer ring stacked on the stacking support rod 22, thereby ensuring the stability during unloading and loading operations.

[0029] Preferably, a plurality of rollers 11 and a plurality of supporting feet 12 are provided at the lower end of the frame 1, and the supporting feet 12 are screwed to the frame 1. Through the above structure, the supporting feet 12 are rotated to leave the position against the ground, and the frame 1 can be conveniently pushed by the rollers 11, so that the frame 1 can be moved to the desired working position. After the frame 1 is moved into place, the supporting feet 12 are rotated to make them against the ground, and a limit is imposed on the movement of the frame 1, so that the frame 1 can be stably ensured in the working position, which is convenient for workers to operate.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
