Description

Technical Field

[0001] This utility model relates to the technical field of riveting, and in particular to a novel precision hydraulic press for pin connectors. Background Technology

[0002] The ejector pin connector is riveted together from three basic components: a pin shaft, a spring, and a pin tube. The spring structure is located inside the connector, and a riveting mechanism is required to assemble the three basic components. The riveting process is usually provided by a hydraulic press. However, the hydraulic cylinder itself does not provide enough power, and the riveting process is unstable. In addition, the lower end of the existing cylinder is mounted on the upper end of the stand. The driving end of the cylinder needs to pass through the stand and apply downward force. The reaction force on the cylinder is pulled at the connection between the stand and the cylinder, resulting in poor stress distribution. Utility Model Content

[0003] One objective of this invention is to provide a novel precision hydraulic press for ejector pin connectors, which changes the fixed end connection position of the heavy-duty oil cylinder and adds a hydraulic station and a booster to increase the riveting force and ensure the riveting forming effect of the ejector pin connector.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A novel precision hydraulic press for pin connectors includes a frame, a hydraulic station, a booster, and a vertical frame. The vertical frame stands on the upper end of the frame, and an upper mounting plate is installed on the upper end of the vertical frame. A heavy-duty hydraulic cylinder is fixedly connected to the lower end of the upper mounting plate. A sliding plate is vertically connected downward to the driving end of the heavy-duty hydraulic cylinder, and a riveting upper plate is fixedly connected to the sliding plate. A pressure-bearing lower plate is installed on the lower end of the vertical frame. The hydraulic station and the booster are both located at the lower end of the frame. The hydraulic station is connected to the booster, and the booster is connected to the heavy-duty hydraulic cylinder.

[0006] As a preferred technical solution, the support frame is equipped with pillars around its perimeter, and the sliding plate is fixed with an oil-free bushing around its perimeter. The oil-free bushing slides vertically on the pillars.

[0007] As a preferred technical solution, upper limit blocks are fixed on both sides of the sliding plate, and positioning holes are provided on the upper limit blocks. Lower limit blocks are provided on both sides of the lower end of the upright, and positioning pins are provided on the lower limit blocks. The positioning pins are inserted into the positioning holes.

[0008] As a preferred technical solution, an indicator light is installed on one side of the frame, and a panel is installed on the other side of the frame. The panel is equipped with a touch screen, an adjustment knob, and a pressure gauge.

[0009] As a preferred technical solution, a feed inlet is provided at the lower front end of the upright frame, and safety light curtains are provided on both sides of the feed inlet along the vertical direction.

[0010] As a preferred technical solution, the lower end of the frame is threadedly connected to a foot, and corner plates are fixed around the lower end of the frame, with the corner plates located on the outside of the foot.

[0011] The beneficial effects of this utility model are as follows: It provides a new type of precision hydraulic press for pin connectors. This new type of precision hydraulic press for pin connectors improves the stability of force by changing the fixed connection position of the heavy-duty oil cylinder. At the same time, it increases the hydraulic pressure by adding a hydraulic station and a booster, ensuring that the riveting of the pin connector is completed smoothly, with high production capacity and fast efficiency.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 4As shown in this embodiment, a novel precision hydraulic press for pin connectors includes a frame 1, a hydraulic station 2, a booster 3, and a stand 4. The stand 4 is erected on the upper end of the frame 1. An upper mounting plate 5 is installed on the upper end of the stand 4. A heavy-duty hydraulic cylinder 6 is fixedly connected to the lower end of the upper mounting plate 5. A sliding plate 7 is vertically connected downward to the drive end of the heavy-duty hydraulic cylinder 6. A riveting upper plate 8 is fixedly connected to the sliding plate 7. A pressure-bearing lower plate 9 is installed on the lower end of the stand 4. The hydraulic station 2 and the booster 3 are both located at the lower end of the frame 1. The hydraulic station 2 is connected to the booster 3, and the booster 3 is connected to the heavy-duty hydraulic cylinder 6.

[0021] The upper end of the heavy-duty hydraulic cylinder 6 is connected to the lower end of the mounting plate 5, so that when the heavy-duty hydraulic cylinder 6 is subjected to force after extending the drive end, it is upward. The entire upright frame 4 serves as the force-bearing structure for the heavy-duty hydraulic cylinder 6. Compared with the structure where the lower end of the heavy-duty hydraulic cylinder 6 is connected to the upper end of the mounting plate 5, the force is supported by the entire upright frame 4, resulting in better stability. In order to ensure that it still has a large force despite its small size, a hydraulic station 2 and a booster 3 are added to assist in driving the heavy-duty hydraulic cylinder 6, driving the sliding plate 7 to move downward, and combining the riveted upper plate 8 with the pressure-bearing lower plate 9 to rivet the ejector pin connector on the fixture.

[0022] The support frame 4 is equipped with support columns 10 around its perimeter, and the sliding plate 7 is fixed with oil-free bushings 11 around its perimeter. The oil-free bushings 11 slide vertically on the support columns 10. Upper limit blocks 12 are fixed on both sides of the sliding plate 7. The upper limit blocks 12 are provided with positioning holes. Lower limit blocks 13 are provided on both sides of the lower end of the support frame 4. Positioning pins 14 are provided on the lower limit blocks 13. The positioning pins 14 are inserted into the positioning holes. When the sliding plate 7 moves up and down, the relative sliding of the support columns 10 and the oil-free bushings 11 ensures the movement of the riveted upper plate 8. When the upper limit blocks 12 and the lower limit blocks 13 on both sides are aligned, the positioning pins 14 are inserted into the positioning holes for alignment, preventing the riveted upper plate 8 from shifting from the pressure-bearing lower plate 9.

[0023] An indicator light 15 is installed on one side of the frame 1, and a panel 16 is installed on the other side of the frame 1. The panel 16 is equipped with a touch screen 17, an adjustment knob 18 and a pressure gauge 19. The indicator light 15 and the pressure gauge 19 can provide timely information about the status of the equipment, and the processing process can be controlled manually through the touch screen 17 and the adjustment knob 18.

[0024] A feed inlet is provided at the lower front end of the upright frame 4. Safety light curtains 20 are installed on both sides of the feed inlet along the vertical direction. Under the action of the safety light curtains 20, the equipment cannot be moved when a person puts the fixture into the pressure plate 9. The heavy-duty hydraulic cylinder 6 can only be controlled when the safety light curtains 20 do not detect an object, thus improving safety.

[0025] The lower end of the frame 1 is connected to a foot 21 by screw threads. Angle plates 22 are fixed around the lower end of the frame 1. The angle plates 22 are located outside the foot 21. When the foot 21 is damaged or shifted, the angle plates 22 support the frame 1 to ensure smooth production.

[0026] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
