[0044] The working process of the utility model is:

[0045] The operator loads the bar blank into the loading plate of the frame and then presses the start button. The loading pushing cylinder extends out, driving the pushing plate bracket to move upward along the guide column. The pushing plate bracket drives the lower pushing plate and the upper pushing plate to extend at the same time, and the lower pushing plate pushes a bar onto the inclined surface of the lower fixed partition. Then the loading pushing cylinder is retracted, and the pushing plate bracket drives the lower pushing plate and the upper pushing plate to retract at the same time. Since the height of the inclined surface on the lower fixed partition is higher than the inclined surface on the upper pushing plate, the bar slides to the inclined surface of the upper pushing plate due to gravity, and then the loading pushing cylinder extends again, and the pushing plate bracket continues to drive the lower pushing plate and the upper pushing plate to extend at the same time, and the upper pushing plate pushes the bar to the inclined surface of the upper fixed partition. The bar slides from the inclined surface of the upper fixed partition to the upper surface of the lower sliding plate by gravity, and then slides from the lower sliding plate to the V-shaped positioning block. At the same time, the lower pushing plate pushes another bar to the lower fixed partition On the inclined surface of the fixed partition; when the photoelectric switch senses that there is material on the V-shaped positioning block, the positioning cylinder drives the positioning cylinder plug to extend, pushes the bar material to one end close to the fixed stopper, and then retracts it to complete the positioning of the bar material. At this time, the collaborative robot takes the grabbing part to the loading and clamping station and grabs the bar material blank with the loading claw of the grabbing part; after grabbing the workpiece blank, the collaborative robot first grabs the processed shaft parts on the bracket of the CNC lathe with the unloading claw of the grabbing part, and then places the bar material blank on the bracket of the CNC lathe with the loading claw. After it is placed in place, the CNC lathe starts processing; the collaborative robot then places the processed shaft parts on the double-layer unloading bin. Since the double-layer unloading bin is at a certain downward angle with the plane, the shaft parts placed on the double-layer unloading bin roll to the bottom of the double-layer unloading bin, completing a loading and unloading process. When the number of workpieces reaches a certain amount, the operator can take the workpieces away.

[0046] Compared with the prior art, the utility model has the following advantages:

[0047] 1. The automatic loading and unloading device for CNC lathe bars provided by the utility model has a high degree of automation. The loading and unloading is completed autonomously by the collaborative robot, and the purchase cost is lower than that of the 6-axis industrial robot;

[0049] 3. The automatic loading and unloading device for CNC lathe bars provided by the utility model has high production efficiency.

[0050] 4. The automatic loading and unloading device for CNC lathe bars provided by the utility model can significantly improve production efficiency, reduce production costs, and create good economic benefits for users.

[0061] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0062] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0063] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0064] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0065] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0066] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components.
