Description

Technical Field

[0001] This utility model relates to the field of cylinder stop block production technology, and in particular to a clamping and flipping mechanism for mass production of cylinder stop blocks. Background Technology

[0002] Cylinder stops are mainly used to control the flow of materials between workstations. By blocking or releasing pallets, they achieve precise positioning and synchronous control of the production line. Some stops can absorb the impact force of high-speed workpiece movement, preventing equipment damage. In emergencies, stops can also quickly stop equipment operation, providing safety protection.

[0003] During the mass production of stop blocks, some stop blocks need to be machined on both sides. This requires disassembling the stop blocks, adjusting the clamping surfaces, and re-clamping them, which is extremely detrimental to continuous production. Frequent disassembly and clamping consumes a lot of time. Moreover, after flipping the stop blocks, it is necessary to determine the orientation of the machining surface, which can easily lead to mirror errors in the machining area. Utility Model Content

The motor is mounted on the inner side of the top of the processing table, the turntable is fixedly mounted on the motor output end, the screw is clamped on the top of the processing table, the friction plate is fixedly mounted on the top of the screw, the limit nut is threadedly connected to the screw, the fixing cylinder is mounted on the inner side of the top of the processing table, and the limit plate is fixedly mounted on the telescopic end of the fixing cylinder. The clamping mechanism is located inside the turntable, and the turntable surface has mounting holes. The limiting cylinder is installed inside the mounting holes on the turntable surface. The clamping mechanism includes a mounting base, a clamping cylinder, a clamping seat, a clamping tube, a friction wheel, a rotating tube, and a pressure block. The mounting base is fixedly located on the outer edge of the turntable, the clamping cylinder is fixedly located inside the mounting base, the clamping tube is fixedly located at both ends of the clamping seat, the friction wheel is fixed to the outer surface of the clamping tube, the rotating tube is movably connected to the telescopic end of the clamping cylinder, and the pressure block is fixedly located at the end of the rotating tube.

[0006] In a preferred embodiment of the present invention, the rotating tube is clamped inside the clamping tube, the pressure block is clamped inside the clamping seat, and guide strips are provided at both ends of the pressure block. A guide groove that cooperates with the pressure block is provided on the inner side of the clamping seat. After placing the workpiece into the clamping seat, drive the clamping cylinder to extend, control the rotating tube to push forward, so that the pressure block is guided forward by the guide bars on both sides, thereby achieving the effect of positioning and clamping the workpiece.

[0007] In a preferred embodiment of this utility model, the surface of the turntable is provided with a mounting hole that mates with the clamping seat, and the clamping tube is movably connected to the mounting hole of the clamping seat on the surface of the turntable.

When the friction wheel passes the friction plate, its surface rubber ring contacts the surface of the friction plate, thereby controlling the clamping seat to rotate 180°.

[0008] In a preferred embodiment of the present invention, the telescopic end of the limiting cylinder penetrates and extends into the mounting hole of the clamping seat, and its telescopic end contacts the side of the clamping seat.

[0014] like Figure 1-5 The clamping and flipping mechanism for mass production of cylinder stop blocks shown includes a processing table 1, a motor 2, a turntable 3, a screw 4, a friction plate 5, a limit nut 6, a fixing cylinder 7, a limit plate 8, a clamping mechanism 9, and a limit cylinder 10. The motor 2 is installed on the inner side of the top of the processing table 1, the turntable 3 is fixedly installed at the output end of the motor 2, the screw 4 is clamped on the top of the processing table 1, the friction plate 5 is fixedly installed at the top end of the screw 4, the limit nut 6 is threadedly connected to the screw 4, the fixing cylinder 7 is installed on the inner side of the top of the processing table 1, the limit plate 8 is fixedly installed at the telescopic end of the fixing cylinder 7, and the clamping mechanism 9 is set... Inside the turntable 3, there is a mounting hole on the surface of the turntable 3. The limiting cylinder 10 is installed inside the mounting hole on the surface of the turntable 3. The clamping mechanism 9 includes a mounting base 91, a clamping cylinder 92, a clamping seat 93, a clamping tube 94, a friction wheel 95, a rotating tube 96, and a pressure block 97. The mounting base 91 is fixedly set on the outer edge of the turntable 3. The clamping cylinder 92 is fixedly set on the inner side of the mounting base 91. The clamping tube 94 is fixedly set on both ends of the clamping seat 93. The friction wheel 95 is fixed to the outer surface of the clamping tube 94. The rotating tube 96 is movably connected to the telescopic end of the clamping cylinder 92. The pressure block 97 is fixedly set on the end of the rotating tube 96.

[0015] Specifically, the rotating tube 96 is clamped inside the clamping tube 94, the pressure block 97 is clamped inside the clamping seat 93, the pressure block 97 is provided with guide strips at both ends, the clamping seat 93 is provided with a guide groove that matches it, the turntable 3 is provided with a mounting hole that matches the clamping seat 93, the clamping tube 94 is movably connected to the mounting hole of the clamping seat 93 on the surface of the turntable 3, the friction wheel 95 is fitted with a rubber ring, the rubber ring on the surface of the friction wheel 95 contacts the surface of the friction plate 5, the length of the friction plate 5 is half the circumference of the friction wheel 95, the telescopic end of the limiting cylinder 10 passes through and extends into the mounting hole of the clamping seat 93, its telescopic end contacts the side of the clamping seat 93, the limiting nut 6 on the surface of the screw 4 is respectively provided on the upper surface and the inner top of the processing table 1, and the limiting plate 8 is located on the outer bottom of the clamping seat 93.

[0016] In this embodiment, the clamping seat 93 is initially in a horizontal state. At this time, the telescopic end of the limiting cylinder 10 extends, and its end plane fits against the side of the clamping seat 93, achieving a limiting and fixing effect. Then, the cylinder stop block workpiece to be processed is placed in the clamping seat 93. Subsequently, the clamping cylinder 92 extends, driving the pressure block 97 to push forward under the guidance of the guide strips on both sides. The rotating tube 96, which is stuck in the clamping tube 94, is pushed forward. One end of the pressure block 97 is inclined to ensure effective clamping of the cylinder stop block workpiece. Then, under the action of the motor 2, the workpiece is transported to the bottom of the processing equipment. At this time, the fixing cylinder 7 extends, causing the limiting plate 8 to rise. The limiting plate 8 fits against the bottom of the clamping seat 93, thereby achieving limiting and fixing, which facilitates the processing work.

[0017] Furthermore, after processing on one side is completed, the fixing cylinder 7 retracts, causing the limiting plate 8 to move downwards. The motor 2 continues to rotate. When the friction wheel 95 contacts the surface of the friction plate 5, the limiting cylinder 10 retracts, and under the drive of the motor 2, the friction wheel 95 rolls on the surface of the friction plate 5, thereby causing the clamping seat 93 to rotate 180° through the clamping tube 94 to complete the flipping. The limiting cylinder 10 extends to limit and fix, realizing the switching of the processing surface. The friction plate 5 is fixed by clamping the processing table 1 with the limiting nut 6 on the surface of the screw 4, and the clamping height of the friction plate 5 can be adjusted by the surface limiting nut 6. In order to ensure the friction force of the rubber friction ring on the surface of the friction wheel 95, after the reverse side is also processed, the clamping cylinder 92 retracts, releasing the pressure of the pressure block 97 on the workpiece. The workpiece falls automatically, which facilitates the clamping of subsequent new workpieces and realizes continuous production.
