[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] The core of the present invention is to provide a quick loading and unloading fixture that overcomes the pre-constraint in the loading and unloading direction. Compared with the related art, the quick loading and unloading fixture can be used to load and unload the workpiece 5 at a faster speed while positioning the workpiece 5. Another core of the present invention is to provide a processing device including the quick loading and unloading fixture that overcomes the pre-constraint in the loading and unloading direction.

[0060] like Figure 5 As shown, the periphery of the workpiece 5 to be positioned has a positioning groove extending along its own circumference, and the positioning groove is not through in the vertical direction, that is, the top and / or bottom end of the positioning groove is closed and not open.

[0061] Please refer to Figure 1 The present invention provides a quick loading and unloading fixture that overcomes pre-constraints in loading and unloading directions, comprising a supporting assembly 1, a positioning assembly 2 and a first resetting member 3; wherein the supporting assembly 1 has a receiving hole 111 for inserting a workpiece 5 to be positioned; the supporting assembly 1 also has a guiding structure 112, and the extending direction of the guiding structure 112 is perpendicular to the extending direction of the receiving hole 111; the positioning assembly 2 is slidably arranged on the supporting assembly 1 along the guiding structure 112 to be inserted into or withdrawn from the positioning groove of the workpiece 5 to be positioned, and the head end of the positioning assembly 2 has a guiding portion 23 for slidingly cooperating with the workpiece 5 to be positioned, so that the assembly 2 to be positioned can push the positioning assembly 2 to move in the direction of withdrawing from the receiving hole 111; the first end of the first resetting member 3 is arranged on the supporting assembly 1, and the second end is arranged on the positioning assembly 2, so as to drive the positioning assembly 2 to slide and reset.

[0062] like Figures 1 to 4 As shown, a groove extending vertically is provided on the top of the support component 1 as a receiving hole 111. The receiving hole 111 can be a cylindrical groove, a square column groove, etc. When in use, a columnar workpiece 5 to be positioned can be inserted therein; and a guide structure 112 is provided on the support component 1, and a rod-shaped or block-shaped positioning component 2 is arranged on the support component 1 in cooperation with the guide structure 112, so as to be able to slide on the support component 1 along the width direction of the positioning groove, that is, the positioning component 2 can reciprocate in the direction of approaching or moving away from the positioning groove, and a sliding portion, such as a ball or a chamfered portion, is provided on the upper left end of the positioning component 2, so that when the workpiece 5 to be positioned is pushed downward, it will directly slide with the guide portion 23, and can push the positioning component 2 to move toward the right, so that the workpiece 5 to be positioned can continue to move downward and be inserted into the receiving hole 111; correspondingly, a first reset member 3 is provided between the positioning component 2 and the support component 1, and in the process of pushing the positioning component 2 to slide to the right, the first reset member 3 can generate a left reset force to the positioning component 2.

[0063] It should be noted that the number of positioning components 2 and guide structures 112 is not limited, as long as the workpiece 5 to be positioned can be positioned along its width direction. For example, in some specific implementations, the number of positioning components 2 and guide structures 112 is two, and the two guide structures 112 are evenly arranged around the center line of the accommodating hole 111. The two positioning components 2 are slidably arranged on the supporting component 1 along the corresponding guide structures 112; it should also be noted that the type of the guide structure 112 is not limited. For example, the guide structure 112 may include two rows of limit rods, and the number of limit rods in each row is greater than or equal to two; it should also be noted that the type of the first reset member 3 is not limited, as long as it can promote the sliding reset of the positioning component 2. For example, the first reset member 3 may include two first magnets with the same polarity, refer to Figure 1 In the illustrated embodiment, a first magnet is fixed on the supporting component 1 and is located on the right side of the positioning component 2 , and another first magnet is fixed on the right end of the positioning component 2 .

[0064] When it is necessary to install the workpiece 5 to be positioned, push the workpiece 5 to be positioned downward, and in the process of inserting the workpiece 5 to be positioned into the accommodating hole 111, the workpiece 5 to be positioned will first slidably contact the guide portion 23 of the positioning component 2, and squeeze to push the positioning component 2 to move to the right. After the workpiece 5 to be positioned is inserted into place, the workpiece 5 to be positioned is rotated until it is rotated to a position where its positioning groove is relative to the left end of the positioning component 2. The positioning component 2 loses pressure, and under the push of the first reset member 3, the positioning component 2 moves to the left until the left end of the positioning component 2 extends into the positioning groove of the workpiece 5 to be positioned, so as to achieve radial and circumferential positioning of the workpiece 5 to be positioned.

[0065] Based on the above embodiment, the tail end of the positioning component 2 can be rotatably arranged on the supporting component 1, and the head end of the positioning component 2 can be rotated into or out of the accommodating hole 111; a second reset member 4 is provided between the positioning component 2 and the supporting component 1 to promote the rotational reset of the positioning component 2.

[0066] like Figure 2 and Figure 3 As shown, the positioning assembly 2 is rotatably arranged on the supporting assembly 1, and correspondingly, a second reset member 4 is provided between the positioning assembly 2 and the supporting assembly 1. When the left end of the positioning assembly 2 deflects upward, the second reset member 4 can generate a downward reset force to the positioning assembly 2.

[0067] It should be noted that the type of the second reset member 4 is not limited, as long as it can push the positioning assembly 2 to rotate and reset. For example, the second reset member 4 may include two second magnets with the same polarity, as shown in FIG. Figure 1 In the illustrated embodiment, a second magnet is fixed on the supporting component 1 and is located at the lower left end of the positioning component 2 , and another second magnet is fixed at the left end of the positioning component 2 .

[0068] It should also be noted that the positioning component 2 is not limited to the manner in which it can be both slidable and rotatable and is disposed on the supporting component 1. For example, referring to Figure 1 In the orientation shown, a first support plate and a second support plate that are relatively arranged and extend in the transverse direction are arranged on the support assembly 1, a first long strip through hole extending in the transverse direction is provided on the first support plate as a guide structure 112, and a second long strip through hole extending in the transverse direction is provided on the second support plate as a guide structure 112.
