Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to a pressure plate rotary clamping cylinder. Background Technology

[0002] A clamping cylinder is a type of pneumatic cylinder used in industrial equipment, commonly found in machining and automated assembly lines. Its main function is to clamp workpieces, ensuring they do not move during processing.

[0003] Existing clamping cylinders typically consist of components such as a cylinder body, piston, piston rod, and pressure plate. They are driven by gas pressure to move the piston and piston rod, which in turn drives the pressure plate on the piston rod to move, thereby clamping or releasing the workpiece.

[0004] However, once the existing clamping cylinder is installed on the equipment, the horizontal angle of the pressure plate on it is also fixed, and the horizontal angle of the pressure plate is difficult to adjust according to actual needs. If you want to adjust the horizontal angle of the pressure plate, you can only disassemble the entire clamping cylinder and readjust the installation angle position of the clamping cylinder, which is quite troublesome. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a rotary clamping cylinder with a pressure plate.

[0006] The purpose of this utility model is achieved through the following technical solution: a pressure plate rotary clamping cylinder, including a piston cylinder, a rotating component, a pressure plate, and a connecting rod. The piston cylinder includes a cylinder body, a mounting part on the cylinder body, and a circular boss on the mounting part. The piston cylinder is provided with a telescopic piston rod, which passes through the circular boss, and the circular boss and the piston rod are coaxially arranged.

[0007] The rotating component includes a rotating body fitted onto a circular boss and rotatable about the center line of the circular boss, with a locking screw connected to the rotating body; the pressure plate is rotatably connected to the upper end of the piston rod, one end of the connecting rod is rotatably connected to the pressure plate, and the other end of the connecting rod is rotatably connected to the rotating component.

[0008] In this invention, the piston rod extends and retracts, causing the pressure plate to rotate in a vertical plane, thereby clamping or releasing the workpiece. When the locking screw on the rotating component is loosened, the rotating component can rotate around the circular boss. When it is necessary to adjust the horizontal installation angle of the pressure plate, first loosen the locking screw on the rotating component, then rotate the rotating component. The rotating component will cause the pressure plate to rotate horizontally, thus adjusting the horizontal angle of the pressure plate. When the pressure plate rotates to the target angle position, the rotating component stops rotating, and the locking screw is tightened. After the locking screw is tightened, the rotating component clamps the circular boss, ensuring that the horizontal angle of the pressure plate does not change. In this invention, after the clamping cylinder is installed, the horizontal direction of the pressure plate can be flexibly adjusted through the rotating component without disassembling the entire clamping cylinder and readjusting its installation angle, making the adjustment process more convenient.

[0009] Preferably, the circular boss has an annular groove on its circumferential surface, and a limiting shaft is connected to the rotating body, with one side of the limiting shaft embedded in the annular groove.

[0010] Preferably, the rotating body has a circular through hole, a circular boss is located in the through hole on the rotating body, the rotating body has a gap, a screw through hole is provided on one side of the gap, and a threaded hole corresponding to the screw through hole is provided on the other side of the gap. The locking screw passes through the screw through hole and is connected to the threaded hole.

[0011] Preferably, the rotating body is provided with a connecting boss, and one end of the connecting rod is rotatably connected to the connecting boss on the rotating body.

[0012] Preferably, the upper surface of the circular boss is provided with a scale.

[0013] Preferably, the cylinder body is provided with a piston chamber, the cross-section of which is circular, and a piston is connected in the piston chamber, with the lower end of the piston rod connected to the piston.

[0014] Preferably, the piston cylinder is provided with a first gas passage and a second gas passage. One end of the first gas passage is connected to the piston chamber, and the other end of the first gas passage is provided with a first bottom interface and a first side interface. The first bottom interface is located on the lower end face of the mounting part, and the first side interface is located on the side of the mounting part. One end of the second gas passage is connected to the piston chamber, and the other end of the second gas passage is provided with a second bottom interface and a second side interface. The second bottom interface is located on the lower end face of the mounting part, and the second side interface is located on the side of the mounting part.

[0015] Preferably, the mounting part is provided with mounting holes.

[0016] The beneficial effects of this utility model are: after the clamping cylinder is installed, the horizontal direction of the pressure plate can be flexibly adjusted by the rotating part, without having to disassemble the entire clamping cylinder and readjust the installation angle of the clamping cylinder, making the adjustment process more convenient.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0028] like Figures 1 to 9 As shown, a rotary clamping cylinder includes a piston cylinder 1, a rotating component 2, a pressure plate 5, and a connecting rod 4. The piston cylinder 1 includes a cylinder body 1-1, a mounting part 1-2 on the cylinder body 1-1, and a circular boss 1-5 on the mounting part 1-2. The piston cylinder 1 is provided with a telescopic piston rod 3, which passes through the circular boss 1-5. The circular boss 1-5 and the piston rod 3 are coaxially arranged.

[0029] The rotating component 2 includes a rotating body 2-1 sleeved on a circular boss 1-5 and rotatable around the center line of the circular boss 1-5. A locking screw 7 is connected to the rotating body 2-1. The pressure plate 5 is rotatably connected to the upper end of the piston rod 3. One end of the connecting rod 4 is rotatably connected to the pressure plate 5, and the other end of the connecting rod 4 is rotatably connected to the rotating component 2.

[0030] In this invention, the piston rod 3 extends and retracts, causing the pressure plate 5 to rotate in a vertical plane, thereby clamping or releasing the workpiece 13. When the locking screw 7 on the rotating part 2 is loosened, the rotating part 2 can rotate around the circular boss 1-5. When it is necessary to adjust the horizontal installation angle of the pressure plate 5, first loosen the locking screw 7 on the rotating body 2-1, then rotate the rotating part 2. The rotating part 2 will cause the pressure plate 5 to rotate horizontally, thereby adjusting the horizontal angle of the pressure plate 5. When the pressure plate 5 rotates to the target angle position, the rotating part 2 stops rotating, and the locking screw 7 is tightened. After the locking screw 7 is tightened, the rotating body 2-1 clamps the circular boss 1-5, ensuring that the horizontal angle of the pressure plate 5 does not change. In this invention, after the clamping cylinder is installed, the horizontal direction of the pressure plate 5 can be flexibly adjusted through the rotating part 2 without disassembling the entire clamping cylinder and readjusting its installation angle, making the adjustment process more convenient.

[0031] The cylinder body 1-1, mounting part 1-2, and circular boss 1-5 are integral structures. The cylinder body 1-1 contains a piston chamber 1-4 with a circular cross-section. A piston 10 is connected to the piston chamber 1-4, and the lower end of the piston rod 3 is connected to the piston 10. The cross-section of the piston 10 is the same as that of the piston chamber 1-4, both being circular. The piston 10 can rotate around its central axis within the piston chamber 1-4. The piston cylinder 1 has a guide hole through which the piston rod 3 extends outward. The guide hole is located at the center of the circular boss 1-5.

[0032] The lower end of the cylinder body 1-1 is provided with a base plate 1-3, which will seal the lower end of the cylinder body 1-1.

[0033] The circular boss 1-5 has an annular groove 1-6 on its circumferential surface. A limiting shaft 6 is connected to the rotating body 2-1, and one side of the limiting shaft 6 is embedded in the annular groove 1-6. In this invention, through the cooperation between the limiting shaft 6 and the annular groove 1-6, the rotating body 2-1 can be stably fitted onto the circular boss 1-5, and the rotating body 2-1 will not detach from the circular boss 1-5.

[0034] The rotating body 2-1 has a circular through hole, and a circular boss 1-5 is located in the through hole of the rotating body 2-1. The rotating body 2-1 has a slot 2-3, with a screw through hole on one side of the slot 2-3 and a threaded hole corresponding to the screw through hole on the other side. The locking screw 7 passes through the screw through hole and connects to the threaded hole. When the locking screw 7 is tightened, the rotating body 2-1 holds the circular boss 1-5 tightly, preventing the rotating body 2-1 from rotating; when the locking screw 7 is loosened, the rotating body 2-1 can rotate around the circular boss 1-5.

[0035] The rotating body 2-1 is provided with a connecting boss 2-2, and one end of the connecting rod 4 is rotatably connected to the connecting boss 2-2 on the rotating body 2-1. The connecting boss 2-2 and the rotating body 2-1 are integrally formed.

[0036] A scale 8 is provided on the upper surface of the circular boss 1-5. The operator can easily determine the current horizontal direction of the pressure plate 5 by observing the scale 8, which facilitates the adjustment of the horizontal direction of the pressure plate 5.

[0037] Furthermore, the piston cylinder 1 is provided with a first gas passage 1-12 and a second gas passage 1-13. One end of the first gas passage 1-12 is connected to the piston chamber 1-4, and the other end of the first gas passage 1-12 is provided with a first bottom interface 1-7 and a first side interface 1-9. The first bottom interface 1-7 is provided on the lower end face of the mounting part 1-2, and the first side interface 1-9 is provided on the side of the mounting part 1-2. One end of the second gas passage 1-13 is connected to the piston chamber 1-4, and the other end of the second gas passage 1-13 is provided with a second bottom interface 1-8 and a second side interface 1-10. The second bottom interface 1-8 is provided on the lower end face of the mounting part 1-2, and the second side interface 1-10 is provided on the side of the mounting part 1-2. The first gas passage 1-12 is connected to the piston chamber 1-4 on one side of the piston 10, and the second gas passage 1-13 is connected to the piston chamber 1-4 on the other side of the piston 10. Each gas passage has a side port and a bottom port. The operator can choose either the side port or the bottom port to connect to the air pump according to the actual installation environment of the clamping cylinder. The other port can be blocked by the plug 9 to prevent gas leakage. In addition, the other port can also be used as an expansion port, where pressure sensors and other components can be installed to monitor the intake pressure.

[0038] The mounting section 1-2 is provided with mounting holes 1-11. The clamping cylinder can be fixedly mounted to the corresponding equipment or workbench through the mounting holes 1-11.

[0039] like Figure 9 As shown, the clamping cylinder is fixedly installed on the worktable 12, and the workpiece 13 to be clamped is located on one side of the clamping cylinder. The workpiece 13 is pressed by the pressure plate 5, thereby keeping the workpiece 13 in a fixed state.

[0040] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model.
