This servo hydraulic riveting machine is provided with a first support plate and a second support plate, which are vertically distributed. The front end of the workpiece is placed on the first support plate, and the left end is placed on the second support plate. The first support plate can move back and forth through a movable frame to adjust the front and back positions of the workpiece, and the second support plate can move left and right through a sliding sleeve to adjust the left and right positions of the workpiece, facilitating the positioning of the workpiece.

[0020] The following will further illustrate the technical solutions of the present invention with reference to the drawings and through specific embodiments.

[0021] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0022] Please refer to Figures 1-4As shown in the figure, a new type of servo hydraulic riveting machine includes a lower riveting die 1, an upper riveting die 2, a connecting piece 3, an oil cylinder 4, a type clip 5, a ring block 6, a guide rod 7, a hole block 8, a spring 9, a bottom plate 11, a cylinder 13 and an L-shaped frame 15. The lower riveting die 1 is installed on one side of the middle of the bottom plate 11, and the upper riveting die 2 located directly above the lower riveting die 1 is connected to the output end of the oil cylinder 4 through the connecting piece 3. Three hole blocks 8 are installed around the connecting piece 3 in a triangular shape distribution, and a guide rod 7 is installed in each hole block 8. Two type clips 5 are symmetrically arranged on both sides of the upper riveting die 2, and the ring blocks 6 located at the tops of the two type clips 5 are respectively thread-fixed to the bottom ends of the two guide rods 7 at the symmetric positions. A spring 9 is sleeved on the top of each guide rod 7. A circular hole 1101 is opened on the other side of the middle of the bottom plate 11, and a pneumatic fixture 14 is installed in the circular hole 1101. The output end of the cylinder 13 is connected to the corresponding part on one side of the bottom plate 11.

[0023] The tops of the guide rods 7 are connected to each other through an arc-shaped block 10, which plays a role in connecting and fixing the tops of the three guide rods 7 and helps to form a triangular stable structure.

[0024] One end of the top of the L-shaped frame 15 is fixedly connected to the cylinder body end of the oil cylinder 4, and the bottom end of the L-shaped frame 15 is installed at the middle position of one end of the table board 17, which plays a role in connecting between various structures.

[0025] The cylinder body part of the cylinder 13 is fixedly installed on the table board 17. Guide rails 12 are symmetrically installed on the top of the table board 17, and the bottom plate 11 is slidably connected between the two guide rails 12. Through the guide rails 12 and the combined cylinder 13, the effect of pushing the connected bottom plate 11 is achieved.

[0026] The bottom of the table board 17 is installed on the top of the box body 18, and a rivet feeding module 16 is installed on the part of the table board 17 located inside the box body 18. The rivet output port of the rivet feeding module 16 is exposed on the table board 17 so as to vertically send the rivet into the pneumatic fixture 14, and at the same time, the pneumatic fixture 14 is used to hold the rivet in an upright state.

[0027] Working principle: The operation of cylinder 13 to extend drives the bottom plate 11 to move outward along the guide rail 12, and places the vertically standing rivet in the pneumatic fixture 14 directly below the upper riveting die 2. The extension of the oil cylinder 4 drives the connecting piece 3 and the connected parts to move downward, so that the two symmetrically distributed clamping pieces 5 move downward until they reach the top of the rivet, and the deformation between the bottoms of the two clamping pieces 5 is used to expand and clamp and fix the top part of the rivet. At the same time, the end face of the top of the rivet contacts the bottom end face of the upper riveting die 2. After the rivet is placed, the cylinder 13 contracts to reset the bottom plate 11, so that the top of the lower riveting die 1 is placed directly below the bottom end of the upper riveting die 2. Then, the aligned and overlapped riveting holes of the two workpieces are placed on the lower riveting die 1, and the reset oil cylinder 4 extends again, so that the upper riveting die 2 and the rivet move downward until the riveting is completed. When the bottom end of the clamping piece 5 contacts the surface of the workpiece and the upper riveting die 2 continues to move downward to perform riveting, the clamping piece 5 and the guide rod 7 connected through the ring block 6 are stationary at this time, while the hole block 8 on the connecting piece 3 moves downward and pulls the spring 9 to be in an extended state, so as to reset the clamping piece 5 later and prevent it from hindering the riveting process;

[0028] Compared with the prior art, by arranging two symmetrically distributed clamping pieces 5 around the upper riveting die 2, and at the same time using the extension of the oil cylinder 4 to insert and fix the top of the vertically standing rivet in the pneumatic fixture 14 between the two clamping pieces 5, it has the structural function of clamping the rivet and placing it at the bottom end face of the upper riveting die 2, and the rivet is placed and aligned correctly, preventing riveting deviation and improving the riveting quality. After the clamping piece 5 contacts the surface of the workpiece, it remains stationary, and the hole block 8 on the connecting piece 3 moves downward and pulls the spring 9 to be in an extended state, so as to reset the clamping piece 5 later and prevent it from hindering the riveting process.
