[0035] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] As Figure 1 shown:

[0037] A mechanical device for automatically loading and pressing aluminum profiles with multiple holes and multiple positions includes a frame 1 and a press 2; it also includes a press 2, a floating mechanism 3, a lower die 4, a guide pin 5, a lifting device 6, a supporting device 7 and an automatic loading device 8; the press 2 is fixed on the frame 1; the floating mechanism 3 is installed directly below the working end of the press 2; the lower die 4 is horizontally movably arranged on the floating mechanism 3, the axis of the guide pin 5 is vertically arranged on the lower die 4 and is in clearance fit with the lower die 4, a first spring 5a for providing axial elastic support to the guide pin 5 is arranged at the bottom of the guide pin 5, and the top end of the guide pin 5 is conical; the lifting device 6 is installed on the frame 1 and is used to control the lifting of the floating mechanism 3; the supporting device 7 is arranged below the floating mechanism 3 and is used to provide support during pressing.

[0038] Based on the above embodiments, the automatic feeding device 8 of the present application is preferably an automatic gripper driven by a synchronous belt slide for displacement, and other conventional feeding structures can also be selected. The frame 1 is a C-shaped frame. During operation, the mother board S2 is moved manually or automatically below the working end of the press 2, so that the working end of the press 2, the mounting hole on the mother board S2 for rivet S1 to be press-fitted, and the guide pin 5 are successively in the same straight line from top to bottom. The controller sends a signal to the lifting device 6. After receiving the signal, the lifting device 6 drives the floating mechanism 3, the lower die 4 on the floating mechanism 3, and the guide pin 5 to move upward together, so that the tip of the guide pin 5 penetrates out of the mounting hole of the mother board S2. When the position of the mounting hole is offset, the lower edge of the mounting hole abuts against the peripheral wall of the conical structure at the top of the guide pin 5, and the reaction force drives the guide pin 5 to horizontally float on the floating mechanism 3 with the lower die 4 until the top of the guide pin 5 penetrates out of the top of the mounting hole when it is collinear with the axis of the mounting hole, and at the same time, the top of the lower die 4 abuts against the bottom end of the mother board S2. The automatic feeding device 8 moves the rivet S1 from the material box and places it on the top of the guide pin 5. At this time, the conical structure at the top of the guide pin 5 can also provide guidance for the rivet S1 to eliminate errors. The automatic feeding device 8 moves out of the way, and the controller sends a signal to the press 2. After receiving the signal, the working end of the press 2 presses down. The guide pin 5 is pressed and contracts into the lower die 4 against the supporting action of the first spring 5a to avoid the mounting hole, and at the same time, the rivet S1 is press-fitted onto the mounting hole along with the guiding action of the guide pin 5. The supporting device 7 provides support for the bottom of the floating mechanism 3 during the press-fitting operation. After the press-fitting is completed, the controller sends a signal to the lifting device 6. After receiving the signal, the lifting device 6 drives the floating mechanism 3, the lower die 4, and the guide pin 5 to descend. The mother board S2 is moved again to press-fit the rivet into the second mounting hole, and so on in a cycle.

[0039] Further, to solve the problem of how to make the guide pin 5 perform floating motion, as Figure 3 shown:

[0040] The floating mechanism 3 includes a mounting box 3a, a first horizontal slider 3b, a second horizontal slider 3c, a second spring 3d, and a third spring 3e; the mounting box 3a is fixed on the movable end of the lifting device 6, the first horizontal slider 3b is slidably arranged inside the cavity of the mounting box 3a, the second horizontal slider 3c is slidably arranged on the mounting box 3a, the sliding directions of the first horizontal slider 3b and the second horizontal slider 3c are perpendicular to each other, and the lower die 4 is mounted on the second horizontal slider 3c; there are a pair of second springs 3d, which are respectively mounted on the opposite sides of the first horizontal slider 3b and one end abuts against the inner wall of the mounting box 3a, and there are a pair of third springs 3e, which are respectively mounted on the opposite sides of the second horizontal slider 3c and one end abuts against the inner wall of the mounting box 3a.

[0041] Based on the above embodiments, the present application enables the lower die 4 mounted on the second horizontal slider 3c to have degrees of freedom of movement in the horizontal X-axis and Y-axis directions through the sliding structure of the first horizontal slider 3b and the second horizontal slider 3c stacked on top of each other. Therefore, a relatively large range of movement space is provided for the lower die 4 and the guide pin 5. The second spring 3d and the third spring 3e respectively provide floating elastic support for the first horizontal slider 3b and the second horizontal slider 3c in a layered manner. The first horizontal slider 3b and the second horizontal slider 3c have a tendency to be centered, preventing the lower die 4 and the guide pin 5 from moving around randomly and ensuring the stability of the working effect.

[0042] Furthermore, to solve the problem of further improving the degree of automation to prevent errors and omissions, as Figure 3 shown:

[0043] A first monitoring component 3f for monitoring the telescopic state of the guide pin 5 is also installed on the mounting box 3a.

[0044] Based on the above embodiments, the first monitoring component 3f adopted in the present application is preferably an infrared optoelectronic sensor. Its emitting end extends into the interior of the mounting box 3a, and the telescopic state of the guide pin 5 is monitored by detecting whether the bottom end of the guide pin 5 blocks its emitting end. On the one hand, it can indirectly feedback to the controller the movement displacement of the rivet S1 relative to the mother board S2 during press-fitting. When the displacement reaches the threshold, it indicates that the press-fitting is completed, and the next press-fitting operation can be carried out quickly. At the same time, problems such as whether the guide pin 5 is stuck can be observed accordingly, ensuring that the guide pin 5 only contracts when the press 2 presses down, and thus it can be judged whether there is a fault in the device.

[0045] Furthermore, to solve the problem of how to provide a stable support effect for structures such as the floating mechanism 3 during press-fitting, as Figure 4 shown:

[0046] The support device 7 includes a first support block 7a, a second support block 7b, and a second linear driver 7c; the first support block 7a is directly or indirectly fixed to the bottom of the floating mechanism 3; the second linear driver 7c is installed below the first support block 7a, and its working direction is set along the horizontal direction; the second support block 7b is installed on the working end of the second linear driver 7c. In the working state, the upper end of the second support block 7b abuts against the lower end of the first support block 7a, and a self-locking inclined surface is provided at the part where the second support block 7b and the first support block 7a abut against each other.

[0047] Based on the above embodiments, the second linear driver 7c adopted in the present application is preferably a slide cylinder. During non-pressing operations, the first support block 7a and the second support block 7b are in a separated state in the horizontal direction. When support force needs to be provided, the controller sends a signal to the second linear driver 7c. After receiving the signal, the second linear driver 7c drives the second support block 7b to move horizontally towards the first support block 7a. The self-locking inclined surfaces at the upper end of the second support block 7b and the lower end of the first support block 7a press the first support block 7a upwards on one hand and can play a self-locking role on the other hand. As shown in the figure, the first support block 7a is directly fixed to the bottom of the working end of the lifting device 6 and is indirectly fixed to the floating mechanism 3. It can also be connected directly to the lower end of the lower die 4 by passing through or bypassing the working end of the lifting device 6 to provide its supporting effect. The first support block 7a, the second support block 7b, and the second linear driver 7c decompose the reaction force directly transmitted to the driving structure into two component forces in the horizontal and vertical directions, reducing the direct impact on the driving elements and improving the overall service life of the structure.

[0048] Further, to solve the problem of how to control the lifting of the floating mechanism 3, as Figure 2 shown:

[0049] The lifting device 6 includes a lifting plate 6a and a first linear driver 6b; the lifting plate 6a is slidably connected to the frame 1 in the vertical direction, and the floating mechanism 3 is installed above the lifting plate 6a; the first linear driver 6b is fixed to the frame 1, the output shaft of the first linear driver 6b is connected to the lifting plate 6a, and the working direction of the first linear driver 6b is vertically upward and is located on the side of the press 2.

[0050] Based on the above embodiments, the present application avoids blocking the area below the working end of the press 2 by placing the first linear driver 6b on the side of the press 2, and it is preferably a cylinder. The controller drives the lifting plate 6a to lift through the first linear driver 6b to control the lifting of the floating mechanism 3, the lower die 4, and the guide pin 5.

[0051] Further, to solve the problem of how to ensure that the rivet S1 and the mother board S2 are transferred in place, as Figure 1 shown:

[0052] The frame 1 is further provided with a second monitoring component 1a, and the working direction of the second monitoring component 1a faces directly below the working end of the press 2.

[0053] Based on the above embodiments, the present application monitors the positions of the rivet S1 and the mother board S2 below the press 2 through the second monitoring component 1a for auxiliary positioning, improving the automatic feeding device 8 that transfers the frame 1 or the structure that transfers the mother board S2 to accurately move the workpiece in place, thereby solving the above problems.

[0054] The above embodiments merely represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
