In this embodiment, all the power sources of the movable structures are cylinders.

Referring to fig. 2, the directional transportation tunnel 1 is horizontally configured to be a three-section structure, the three-section structure includes a conveying section 1.1, a first pushing section 1.2, and a second pushing section 1.3 in sequence, the conveying section 1.1, the first pushing section 1.2, and the second pushing section 1.3 are all linear tunnel sections, wherein the first pushing section 1.2 and the second pushing section 1.3 are disposed on a supporting plate 7, a conveying structure and two shielding plates surround to form the conveying section 1.1, the conveying structure is located below the conveying section 1.1, the two shielding plates are located on two sides of the conveying section 1.1, and the conveying structure is a horizontal electric conveying belt in this embodiment; the conveying section 1.1 is parallel to the second pushing section 1.3, and the first pushing section 1.2 is perpendicular to the conveying section 1.1 or the second pushing section 1.3; for convenience of describing the concept of direction introduced herein, please refer to fig. 1 and 2, the moving direction of the to-be-processed part in the conveying section 1.1 in the drawings is defined as the Y-axis direction, and therefore the moving direction of the to-be-processed part in the second pushing section 1.3 is also the Y-axis direction, and the moving direction of the first pushing section 1.2 in the drawings is defined as the X-axis direction; the first pushing section 1.2 and the second pushing section 1.3 both form a notch on the side surface of the support block plate 7, and the side notches have the function of enabling the turning pushing mechanism 2 to push the first pushing section 1.2 and the second pushing section 1.3 to be in direct contact with a part to be processed and push the part to be processed to move inside the directional conveying tunnel 1, so that the total number of the turning pushing mechanisms 2 is two, namely the first pushing mechanism 2.1 and the second pushing mechanism 2.2, the first pushing mechanism 2.1 is arranged at the side notch of the support block plate 7 at the intersection of the transportation section 1.1 and the first pushing section 1.2 and is used for pushing the part to be processed in the directional conveying tunnel 1 to move on the first pushing section 1.2, namely pushing the part to be processed to move along the X axial direction; the second pushing mechanism 2.2 is disposed in a side gap of the support block plate 7 at a junction of the first pushing section 1.2 and the second pushing section 1.3, and is configured to push a part to be processed in the directional conveying tunnel 1 to move on the second pushing section 1.3, that is, push the part to move along the Y axis. In order to ensure that the turning pushing mechanism 2 does not damage the surface quality of the part to be processed, the contour of a contact surface of the part to be processed and the first pushing mechanism 2.1 is matched with the top end of the first pushing mechanism 2.1; the contact surface profile of the part to be processed contacting the second pushing mechanism 2.2 is matched with the top end of the second pushing mechanism 2.2. The tail end of the directional transportation tunnel 1 is provided with a detection device, the detection device is a gravity sensor in the embodiment, when the part to be processed exists at the tail end of the directional transportation tunnel 1, the turning pushing mechanism 2 is in a standby signal state, once the part to be processed at the tail end of the directional transportation tunnel 1 is clamped or separated in other modes, the gravity sensor immediately sends a pushing signal to the pushing mechanism, and the part to be processed is conveyed to the tail end of the directional transportation tunnel 1. Referring to fig. 1, in order to prevent the parts to be processed from being ejected from the directional conveying tunnel 1 due to elastic potential energy accumulated by elastic deformation caused by dislocation in the process of being pushed, a limiting cover plate 5 is disposed above the conveying section 1.1 and the first pushing section 1.2 of the directional conveying tunnel 1, i.e., above the supporting plate 7.

Referring to fig. 3, two sides of the upper end of the part partition table 4 are provided with object carrying blocks 4.1, the part partition table 4 is driven by the cylinder to be capable of moving back and forth along the X-axis direction and the-X-axis direction, the-X axis direction is the opposite direction of the X-axis direction, when the clamping and conveying device 3 moves to the position above the part partition table 4, one of the object carrying blocks 4.1 on the part partition table 4 is located right below the clamping and conveying device 3, and at this time, the other object carrying block 4.1 is located in the processing area of the next step; in order to facilitate the clamping and conveying device 3 to clamp the part to be processed at the tail end of the directional conveying tunnel 1, two clamping gaps a are formed in the support block plates 7 on the two sides of the tail end of the directional conveying tunnel 1.

The process of transporting the parts to be machined in this embodiment is as follows: placing a part to be processed on a conveying section 1.1 of the directional conveying tunnel 1, driving the part to be processed on the conveying section 1.1 to move towards the x-axis direction by a conveying belt below the conveying section 1.1, waiting for the first pushing mechanism 2.1 to push the part to be processed when the part reaches the intersection of the conveying section 1.1 and the first pushing section 1.2, transmitting a pushing signal to the first pushing mechanism 2.1 by a gravity sensor if the tail end of the directional conveying tunnel 1 is free of a heavy object, pushing the part to be processed to the tail end of the first pushing section 1.2 by the first pushing mechanism 2.1, and pushing the part to be processed to the tail end of the directional conveying tunnel 1 by the second pushing mechanism 2.2 after waiting for a certain time. It should be noted here that the first pushing mechanism 2.1 and the second pushing mechanism 2.2 receive the pushing signal at the same time, but the second pushing mechanism 2.2 does not execute the pushing command immediately, but delays the pushing, in order to wait for the first pushing mechanism 2.1 to push the part to be processed to the front end of the second pushing mechanism 2.2. When a part to be processed reaches the tail end of the directional conveying tunnel 1, the clamping and conveying device 3 at the upper end of the directional conveying tunnel moves downwards to clamp the part to be processed, the weight at the upper end of the gravity sensor disappears, a pushing signal for pushing the next part to be processed is transmitted to the turning pushing mechanism 2, the clamping and conveying device 3 conveys the part to be processed to one of the object carrying blocks 4.1 of the part partitioning table 4, the clamping and conveying device 3 ascends to leave to the position above the tail end of the directional conveying tunnel 1, the part partitioning table 4 moves to convey the part to be processed on the object carrying block 4.1 to the next processing area, the other object carrying block 4.1 reaches the position below the descending clamping and clamping position of the clamping and conveying device 3 last time, the next part to be processed is waited to arrive and conveyed to the other processing area, and the process is repeated.

Example 2: referring to fig. 4, the difference from embodiment 1 is that, in the process of transporting the to-be-processed parts, the direction in which the first pushing mechanism 2.1 pushes the to-be-processed parts is also the X-axis direction, the direction in which the second pushing mechanism 2.2 pushes the to-be-processed parts is also the Y-axis direction, but the pushing distances are different, the to-be-processed parts are not directly pushed to the bottom, the distance of each pushing by the first pushing mechanism 2.1 is the X-axis maximum thickness of the to-be-processed parts, and the distance of each pushing by the second pushing mechanism 2.2 is the Y-axis maximum thickness of the to-be-processed parts, so that the to-be-processed parts in the directional conveying tunnel 1 are pushed forward by one grid every pushing, which can store more to-be-processed parts in the directional conveying tunnel.
