[0040] Please see Figure 1 - Figure 8 This utility model provides a technical solution: an automatic pressing machine for universal positioning pins of automotive aluminum parts, including a lower support mechanism 1.

[0049] In this embodiment: an upper top plate 25 is provided on the outside of the sliding plate guide post 24, and a bearing upright 26 is provided at the four corners of the top of the upper top plate 25, and a clamp mounting plate 27 is provided at the bottom of the bearing upright 26;

[0052] In this embodiment: the servo sliding mechanism 3 includes a pressure plate support column 31 installed at the four corners of the bottom of the clamp mounting plate 27, a servo slide group 32 in the middle of the clamp mounting plate 27, and a servo electric cylinder in the middle of the bottom end of the servo slide group 32.

[0053] The sliding of one end of the fixture mounting plate 27 and the corresponding servo slide group 32 is further driven by the energization of the servo electric cylinder to extend and retract the surface of the fixture mounting plate 27.

[0054] In this embodiment: a workpiece clamping mechanism 4 is provided at the top center of the fixture mounting plate 27;

[0055] The workpiece clamping mechanism 4 includes a positioning pin press-fit guide assembly 41 installed at the four corners of the fixture mounting plate 27, a workpiece placement guide block 42 on the top side of the fixture mounting plate 27, a workpiece support column 43 on the side of the workpiece placement guide block 42, and a workpiece placement displacement sensor 44 on the side of the workpiece support column 43.

[0056] The displacement sensor 44 and the workpiece support column 43 are used to implement the expansion and contraction, and the displacement sensor 44 is used for timely linkage.

[0057] In this embodiment: the positioning pin press-fit guide assembly 41 is provided with a positioning pin material-feed photoelectric switch 45 on its side;

[0058] The bottom of the fixture mounting plate 27 is provided with a positioning pin press-fit punch;

[0059] The bottom center of the clamp mounting plate 27 is provided with an elastic pressure foot 28, and the bottom of the elastic pressure foot 28 is provided with a mist suction port 29.

[0060] The elastic presser foot 28, after closing between the upper and lower parts of the clamp mounting plate 27, facilitates the clamping of the positioning pin press-fit punch.

[0061] In this embodiment: a pressure sensor 33 is provided on the side wall of the servo slide group 32, a displacement sensor 34 for limiting is provided on the side wall of the pressure sensor 33, a pressing head 35 is provided on the top of the pressure sensor 33, and a linear guide slide 36 is provided on the surface of the servo slide group 32.

[0062] The pressure sensor 33 is used to detect the position of the fixture, and the pressing head 35 is used for positioning.

[0063] In practical use, the first step is: personnel first use one end of the lower pressure plate support column 31 to realize the combination of automotive aluminum parts;

[0064] At this point, the equipment is mainly used for pressing locating pins on aluminum automotive parts. It can be used to press locating pins of different sizes and with different pressing forces. The operator mounts the servo slide group 32 on the lower part of the fixture mounting plate 27. This low center of gravity results in minimal vibration and good stability during rapid movement. The servo electric cylinder pushes the pressing head 35 to press the locating pin onto the workpiece. The displacement sensor 34, installed between the pressing head 35 and the extension shaft of the servo electric cylinder, detects the pressing force. The pressure sensor 33 measures the pressing distance to confirm whether the locating pin has been pressed to the specified size. The servo slide group 32 drives the servo electric cylinder to move linearly to press two locating pins separately, and different locating pins can be pressed by modifying the center distance parameter between the two pins.

[0065] Step 2: Placement of the workpiece;

[0066] Most workpieces have two mounting locating pins, but the center distance between the two pins is not the same. Therefore, the press-fit servo slide can move freely to the specified coordinates by inputting coordinates through the controller to press the locating pins. The press head on the servo cylinder pushes the locating pin pressing punch, which presses the locating pin in the locating pin pressing guide assembly 41 into the locating pin hole of the workpiece. After pressing, the pressing punch returns to its original position under the action of the spring. The workpiece is placed in the displacement sensor 44, which is a proximity switch. After the workpiece is placed in place, the proximity switch approaches the workpiece to sense that the workpiece has been placed. The locating pin material photoelectric switch 45 is used to detect whether the locating pin has been pre-placed in the locating pin pressing guide assembly 41 to prevent empty pressure.

[0067] At this time, the workpiece needs to be processed. It is placed on the lower fixture. The upper fixture is pushed down and pressed by the pneumatic-hydraulic booster cylinder 17. The elastic pressure foot 28 presses the workpiece evenly. The four pressure limit balance columns are used to limit the pressure height to prevent the upper fixture from tilting due to the different forces of the spring pressure foot. At the same time, the four columns also play a positioning role to prevent the pressure foot from shifting.

[0068] The industrial control computer 151 can be equipped with press-fitting data monitoring and management software, which can store long-term workpiece press-fitting data for future reference, and can remotely monitor and modify the equipment, facilitating after-sales maintenance.

[0069] The contents not described in detail in this description are existing technologies known to those skilled in the art. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
