[0017] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. The terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship shall also be regarded as the scope of the implementation of the utility model without substantial change in the technical content. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work shall fall within the scope of protection of the utility model.
[0018] The utility model provides an automatic feeding machine for the inner shaft of a water pump bearing. Figures 1 to 3 As shown, it includes a machine body 1, and the machine body 1 is a box-type structure, and its inner cavity is provided with a material baffle plate 2, which divides the inner cavity of the machine body 1 into a storage cavity 3 and a lifting cavity 4 distributed front and back. The lower bottom plate of the storage cavity 3 is inclined downward from front to back, and a material passing gap 5 is left between the lower end of the material baffle plate 2 and the lower bottom plate of the storage box 3. In actual application, the bearings are stacked horizontally in the storage cavity 3 along the left and right directions. Since the lower bottom plate of the storage cavity 3 has an inclined angle, the bearing located at the bottom closest to the material passing gap 5 can roll out by itself through the material passing gap 5. The height of the material passing gap 5 is slightly larger than the outer diameter of the bearing to be processed, and only one bearing can pass through at a time. In a preferred embodiment, referring to Figure 2As shown, the baffle plate 2 is connected to the side wall of the machine body 1 by bolts. The installation position of the baffle plate 2 can be adjusted up and down, which can be achieved by using strip bolt holes distributed up and down. Before each use, the up and down positions of the baffle plate 2 are adjusted so that the height of the feed gap 5 is adapted to the outer diameter of the bearing. A fixed step plate 6, a lifting movable part 7 and a lifting cylinder 8 are provided in the material lifting chamber 4. The fixed step plate 6 is fixedly installed on the side wall of the material lifting chamber 4 in the left-right direction. The upper surface of the fixed step plate 6 is inclined downward from front to back, and the front and rear end surfaces are inclined backward from bottom to top. The inner surface of the rear wall of the material lifting chamber 4 is parallel to the rear end surface of the fixed step plate 6, and a discharge port 9 is provided on the upper part of the rear wall of the material lifting chamber 4; a bending portion 71 with an opening facing upward is provided in the middle part of the lifting movable part 7, and the bending portion 71 is nested in the fixed step plate 6 from bottom to top, and the inner surface of the bending portion 71 is in contact with the front and rear end surfaces of the fixed step plate 6. The lifting movable part 7 is provided with a material receiving plate 72 extending forward on the front side of the fixed step plate 6, and a material feeding plate 73 extending backward on the rear side. The rear end of the material feeding plate 73 is close to the inner surface of the rear wall of the material lifting chamber 4, and the material receiving plate 72 and the material feeding plate 73 are both parallel to the upper surface of the fixed step plate 6. In specific applications, the lifting movable part 7 can be formed by bending a whole piece of steel plate. The lifting movable part 7 is driven by the lifting cylinder 8 to move up and down along the front and rear sides of the fixed step plate 6. The lifting cylinder 8 can be fixedly installed at the bottom of the lifting cavity 4. The movable end of the lifting cylinder 8 is connected to the lower bottom surface of the lifting movable part 6. When the lifting movable part 7 is in a low position, the material receiving plate 72 is located at the rear side of the material gap 5, and the feeding plate 73 is flush with the upper surface of the fixed step portion 6. When the lifting movable part 7 is in a high position, the front end surface of the lifting movable part 7 blocks the rear side of the material gap 5, the material receiving plate 72 is flush with the upper surface of the fixed step portion 6, and the feeding plate 73 is located at the front side of the discharge port 9. The upper surface of the fixed step plate 6 and the front and rear widths of the material receiving plate 72 and the feeding plate 73 are slightly larger than the outer diameter of the bearing, and each time a bearing is accommodated above it.
[0019] The working process of the automatic feeding machine is as follows: in the initial state, the lifting movable part 7 is at a high position, and its front end face blocks the material gap 5. The bearing to be processed is in the storage chamber 3. When the feeding operation starts, the lifting movable part 7 moves downward. When it reaches the low position, the bearing closest to the discharge gap 5 in the storage chamber 3 rolls from the discharge gap 5 to the receiving plate 72 by itself. The lifting movable part 7 then moves upward. When it reaches the high position, the first bearing is brought to the upper surface of the fixed step plate 6 by the receiving plate 72 and rolls above it. When the lifting movable part 7 moves downward to the low position again, the first bearing rolls from the fixed step surface 6 to the top of the feeding plate 73, and the second bearing rolls to the top of the receiving plate 72 through the material gap 5. When the lifting movable part 7 moves upward to the high position again, the first bearing is lifted by the feeding plate 73 to the position of the discharge port 9 and discharged from the discharge port 9. The lifting movable part 7 reciprocates up and down to complete the feeding, lifting and discharging of subsequent bearings one by one. Compared with the existing technology, the automatic loader uses a box-type structure for material storage, which can increase the number of bearings stored at a single time and reduce the frequency of manual replenishment; the structure is simple, and each part can be processed by material bending and welding, with low cost. Continuous automatic loading of a single workpiece can be achieved through simple transmission, and the rolling distance of the bearing is reduced during the loading process, which can effectively avoid the problem of material jamming caused by the bearing changing from horizontal to vertical during the rolling process due to unstable center of gravity.
[0020] In a preferred embodiment, referring to Figure 1 As shown, the machine body 1 is provided with a sensing probe 10 at the discharge port 9 for detecting the bearing being discharged. When it is detected that no bearing is discharged after the cylinder is actuated, a warning device can be connected to promptly remind the operator to replenish the material. The sensing probe 10 can use a common laser or infrared probe.
[0021] In order to be applicable to bearings of different lengths, in a preferred embodiment, reference is made to Figure 1 As shown, a limiting plate 11 is provided on one side of the storage cavity 3, and the position of the limiting plate 11 along the left and right direction is adjustable. By adjusting the position of the limiting plate 11, the width of the storage cavity 3 is slightly larger than the length of the bearing to prevent the bearing from changing direction due to the large gap at both ends, thereby preventing the material from getting stuck.
[0022] In a preferred embodiment, referring to Figure 2 As shown, the lower end of the baffle plate 2 is bent backward, and the lower bottom plate of the storage chamber 3 extends backward to the end of the bent portion of the baffle plate 2. A material transfer channel is formed between the bent portion of the baffle plate 2 and the lower bottom plate of the storage chamber 3, and the processed bearings are arranged one by one in the material transfer channel, which can effectively reduce the occurrence of material jamming at the material transfer gap 5.
[0023] In order to facilitate observation and feeding, the storage chamber 3 and the lifting chamber 4 can be set to an open-top structure. In addition, the upper end of the rear wall of the lifting chamber 4 can be set to be bent backward at the position of the discharge port 9, and the bent part is parallel to the feeding plate, and the bearing of the discharge can be rolled out by the feeding plate through the bent part.
[0024] To sum up, the utility model provides an automatic feeding machine for the inner shaft of a water pump bearing, which effectively solves the problems in the prior art such as the small number of parts placed on the tray and the easy change of direction of the bearing during rolling feeding, causing material jamming. The device can be used for the automatic feeding of the inner shaft of a water pump bearing or bearing parts with similar structures, has high utilization value and use significance, and can be widely promoted and applied.
[0025] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
