[0002] The Torx connection technique uses hydraulic and pneumatic pressure to plastically deform two panels, creating a circular connection point where they interlock. The Torx connection is a simple, low-cost process with broad application prospects.

[0003] The relevant connecting equipment includes a workbench and a hydraulic cylinder. The lower mold is fixed on the workbench. The hydraulic cylinder is vertically arranged above the workbench. The upper mold is fixed on the piston rod of the hydraulic cylinder. The hydraulic cylinder drives the upper mold to move back and forth in the vertical direction. The positions of the upper mold and the lower mold correspond. The user places the two plates on the lower mold to fit each other, so that the hydraulic cylinder drives the upper mold to extrude and stamp the connecting plate. The upper mold and the lower mold can jointly extrude the two plates, thereby pressing out a depression on the plates and connecting the two plates to each other.

[0004] The above-mentioned related technical solutions have the following defects: when multiple connection points need to be set on two larger plates, it is inconvenient for users to move the plates, which results in low processing efficiency. Utility Model Content

[0005] In order to facilitate users to move larger plates, the present application provides a bottom plate and bottom shell connecting structure and an upper plate and equipment for processing the bottom plate and bottom shell connecting structure.

[0006] The present application provides a connection structure between a bottom plate and a bottom shell and an upper plate using the following technical solutions:

[0007] A connection structure between a bottom plate and a bottom shell and an upper plate includes a stamped connection plate, the stamped connection plate includes an upper plate and a lower plate, a depression part 1 is stamped on the upper plate, and a depression part 2 is stamped on the lower plate, the depression part 1 is inserted into the depression part 2, and the cross-section of the contact surface between the depression part 1 and the depression part 2 is a wedge-shaped structure.

[0008] By adopting the above technical solution, an upper mold is set above the upper plate and a mold is set below the lower plate, so that the hydraulic cylinder can drive the upper mold to fall and squeeze the stamping connecting plate. A blind hole is opened on the upper top surface of the mold. The size of the upper mold matches the blind hole. When the upper mold presses down the upper and lower plates, depressions are formed on the upper and lower plates and fall into the mold. At this time, an inclined surface is formed between the depressed part one and the depressed part two, thereby forming a wedge-shaped cross section, so that the upper and lower plates can be clamped to each other.

[0009] The present application provides a device for connecting a bottom plate and a bottom shell to an upper plate, which adopts the following technical solution:

[0010] A device for processing the connection structure between the bottom plate, bottom shell and upper plate includes a workbench, a hydraulic cylinder and a displacement mechanism. The workbench is arranged horizontally, the hydraulic cylinder is vertically fixed above the workbench, a mold is arranged on the workbench, an upper mold is arranged on the end of the piston rod of the hydraulic cylinder, and the position of the upper mold corresponds to the position of the mold. The displacement mechanism is arranged on the workbench, and the displacement mechanism is used to vertically lift the stamping connecting plate and slide it to the stamping connecting plate.

[0011] By adopting the above technical solution, a hydraulic cylinder is set on the workbench, so that the hydraulic cylinder can drive the upper die to move vertically. By setting a displacement mechanism on the workbench, when processing the stamping connecting plate, the displacement mechanism is lower than the die, and the die abuts against the lower bottom surface of the lower plate. When the stamping connecting plate needs to be moved and processed at other positions of the stamping connecting plate, the user controls the displacement mechanism to lift. At this time, the displacement mechanism is slidingly connected to the stamping connecting plate, and the user can move the stamping connecting plate horizontally through the displacement mechanism, so that the area to be processed on the stamping connecting plate can be moved to the bottom of the hydraulic cylinder. The user can control the displacement mechanism to move again and make the displacement mechanism fall, so that other positions on the stamping connecting plate can fall on the die, which is convenient for the user to move larger plates.

[0012] Optionally, the displacement mechanism includes a mounting frame and a plurality of balls, wherein the balls are embedded in the mounting frame and are rollingly connected to the mounting frame.

[0013] By adopting the above technical solution, by arranging balls on the mounting frame, the balls are rolled and connected to the mounting frame. When the mounting frame rises and the balls abut against the bottom of the stamped connecting plate, the user can push the stamped connecting plate and slide the stamped connecting plate, thereby improving the processing efficiency of the user.

[0014] Optionally, the mounting frame includes a horizontal portion and two vertical portions, two ends of the horizontal portion are respectively connected to the ends of the two vertical portions, and a plurality of balls are arranged at intervals along the length direction of the mounting frame.

[0015] By adopting the above technical solution, by arranging vertical parts on both sides of the horizontal part, the vertical parts are respectively located on both sides of the mold, so that the balls on the horizontal part and the vertical part can jointly support the stamped connecting plate, so that the stamped connecting plate remains horizontal on the mounting frame.

[0017] By adopting the above technical solution, an axle seat is set under the workbench, so that the rotating rod is rotatably connected to the axle seat. The user can control the rotation of the rotating rod to lift the rotating rod and push up the connecting rod, thereby achieving the effect of controlling the vertical movement of the installation frame.

[0018] Optionally, the middle portion of the rotating rod is rotatably connected to the axle seat, and a pedal is fixed to the end of the rotating rod away from the connecting rod.

[0019] By adopting the above technical solution, by connecting a pedal to the rotating rod, the user can step on the pedal, thereby rotating the rotating rod and lifting the displacement mechanism vertically. After the user moves the stamped connecting plate through the displacement mechanism, by releasing the pedal, the stamped connecting plate can be dropped onto the mold. At this time, the user can control the movement of the hydraulic cylinder and process the stamped connecting plate.

[0020] Optionally, the lower end of the connecting rod is rotatably connected to a rotating wheel, and the rotating wheel is used to abut against the rotating rod.

[0021] By adopting the above technical solution, a rotating wheel is arranged at the lower end of the connecting rod so that the rotating wheel abuts against the rotating rod.

After the upper plate 11 and the lower plate 12 are fitted together, the user uses a stamping device to stamp the upper plate 11 and the lower plate 12, and a cylindrical mold is set under the lower plate 12, and the cylindrical mold is used to squeeze the upper plate 11, so that circular depressions are formed on the upper plate 11 and the lower plate 12. The outer wall of the cross section of the depression 111 forms a wedge-shaped structure, and the depression 111 and the depression 2 121 are clamped to each other through the wedge-shaped inclined surface, so that the upper plate 11 and the lower plate 12 are connected to each other. An overflow portion 122 is formed at the bottom of the second sunken portion 121, and the overflow portion 122 is a circular ring structure. When stamping is performed on the stamped connecting plate 1, the upper plate 11 and the lower plate 12 are deformed. After the upper plate 11 is deformed, a wedge-shaped sunken portion 111 is formed. The upper plate 11 occupies the space of the lower plate 12, so that the top surface of the second sunken portion 121 forms an overflow portion 122. By opening an annular groove in the lower bottom mold, the material of the lower plate 12 can enter the groove and form the overflow portion 122, so that the edge of the connection of the stamped connecting plate 1 is smooth.

[0035] The implementation principle of the embodiment of the present application is: by making the upper plate 11 and the lower plate 12 fit together and squeeze, a circular depression can be stamped out on the stamped connecting plate 1, and a wedge-shaped cross-section is formed between the depressed portion 111 on the upper plate 11 and the depressed portion 121 on the lower plate 12, so that the upper plate 11 and the lower plate 12 are clamped to each other, and the upper plate 11 and the lower plate 12 can be stably connected and have a certain strength, which is convenient for processing.

[0036] The present application embodiment discloses a device for connecting a bottom plate and a bottom shell to an upper plate, referring to Figure 2 and Figure 3 , including a workbench 2, a hydraulic cylinder 3 and a displacement mechanism 4. The workbench 2 is arranged horizontally, and a base 22 is provided on the workbench 2. A mold 23 is detachably connected to the base 22. When the connecting plate 1 is pressed together, the lower plate 12 is horizontally arranged on the mold 23. The hydraulic cylinder 3 is arranged vertically above the workbench 2. The cylinder body of the hydraulic cylinder 3 is fixedly connected to the workbench 2. The piston rod of the hydraulic cylinder 3 moves back and forth vertically. An upper mold 31 is installed on the end of the piston rod of the hydraulic cylinder 3. The upper mold 31 is used to press on the upper plate 11. The position of the upper mold 31 coincides with the position of the mold 23 in the vertical direction. The displacement mechanism 4 is arranged on the workbench 2. The displacement mechanism 4 can move in the vertical direction. When the displacement mechanism 4 moves upward, the displacement mechanism 4 is higher than the base 22 and the mold 23. At this time, the displacement mechanism 4 supports the stamping connecting plate 1. The user can use the displacement mechanism 4 to quickly and conveniently slide the stamping connecting plate 1, so that different positions on the stamping connecting plate 1 can be under the hydraulic cylinder 3, thereby facilitating the user to perform connections at multiple positions on the larger stamping connecting plate 1.

[0037] Reference Figure 2 and Figure 3 The base 22 is a cylindrical structure with a slot 221 formed on the top surface thereof. The mold 23 is a cylindrical structure with a protrusion formed on the bottom of the mold 23 that coincides with the shape of the slot 221. The protrusion is inserted into the slot 221. The user can attach molds 23 of different shapes to the base 22, thereby facilitating the user to press depressions of different sizes on the stamped connecting plate 1.

[0038] Reference Figure 2 and Figure 4 The workbench 2 is provided with a mounting groove 21, and the displacement mechanism 4 is disposed within the mounting groove 21. The displacement mechanism 4 includes a mounting frame 41 and a plurality of ball bearings 42. The mounting frame 41 includes a horizontal portion 411 and two vertical portions 412. The ends of the horizontal portion 411 are respectively fixed to the ends of the two vertical portions 412. The horizontal portion 411 and the vertical portions 412 form a semi-enclosed frame structure, and the base 22 is located in the middle of the semi-enclosed frame. The shape of the mounting frame 41 corresponds to the shape of the mounting groove 21. A plurality of ball bearings 42 are embedded in and rollingly connected to the upper surface of the mounting frame 41, and the ball bearings 42 are spaced apart along the length of the mounting frame 41. The displacement mechanism 4 can move back and forth in the vertical direction. When the mounting frame 41 moves up and is higher than the base 22 and the mold 23, the ball 42 can abut against the lower bottom surface of the lower plate 12. At this time, the user can slide the stamped connecting plate 1 horizontally, thereby moving the stamped connecting plate 1 to a predetermined position below the hydraulic cylinder 3. By controlling the displacement mechanism 4 to move downward, the user can place the stamped connecting plate 1 flat on the mold 23 for pressing.

[0039] Reference Figure 4 A lifting mechanism 5 is provided below the workbench 2 to control the lifting and lowering of the displacement mechanism 4. A connecting rod 43 is connected to the bottom of the mounting frame 41. The connecting rod 43 is vertically arranged. The upper end of the connecting rod 43 is fixed to the mounting frame 41, and the lower end is connected to the lifting mechanism 5. The lifting mechanism 5 controls the vertical movement of the mounting frame 41 through the connecting rod 43.

[0040] Reference Figure 4 The lifting mechanism 5 includes a rotating rod 51, a shaft seat 52, and a pedal 53. The shaft seat 52 is fixed to the ground. The middle portion of the rotating rod 51 is rotatably connected to the shaft seat 52. One end of the rotating rod 51 is connected to the pedal 53, and the other end abuts the bottom of the connecting rod 43. By stepping on the pedal 53, the user can rotate the rotating rod 51 on the shaft seat 52, thereby causing the end of the rotating rod 51 to push up the connecting rod 43, thereby lifting the mounting frame 41. The lower end of the connecting rod 43 is rotatably connected to a rotating wheel 431, which abuts the rotating rod 51. The length of the rotating wheel 431 is perpendicular to the length of the rotating rod 51.

[0041] The implementation principle of the embodiment of the present application is: by arranging a displacement mechanism 4 on the workbench 2, the displacement mechanism 4 can move vertically back and forth, and then the installation frame 41 can be lifted to a position higher than the mold 23. At this time, the stamping connecting plate 1 can slide through the ball bearing 42, so that it is convenient for the user to move the stamping connecting plate 1 to different positions under the hydraulic cylinder 3. By arranging a lifting mechanism 5 under the workbench 2, the user can control the lifting and lowering of the installation frame 41 by stepping on the pedal 53, which is convenient for the user to operate and move the stamping connecting plate 1 alone, thereby improving work efficiency.
