DETAILED DESCRIPTION

[0020] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0021] Depend on Figures 1 to 3 Provided is a valve core automatic punching device, comprising a frame 1, a feeding structure, a punching structure and a valve core processing structure, wherein the feeding structure, the punching structure and the valve core processing structure are fixed on the same end surface of the frame 1, the feeding structure feeds the valve core processing structure, so that the unprocessed valve core flows from the feeding structure to the valve core processing structure, the punching structure punches holes in the valve core in the valve core processing structure, and when the valve core is in a suitable position, the punching structure starts to punch holes in the valve core;

[0022] The feeding structure is an existing technology, and the materials are fed by a vibration feeding structure;

[0023] The valve core processing structure is located at the tail end of the feeding structure for discharging materials. A sensor is provided at the tail end of the feeding structure. When the valve core is located at the discharging port of the feeding structure, the valve core blocks the sensor, thereby causing the valve core processing structure to move toward the feeding structure and clamp, take and place the valve core.

[0024] The punching structure is located on one side of the valve core processing structure. When the valve core in the valve core processing structure moves to the punching structure, the punching structure starts to perform a punching operation on the valve core.

[0025] The valve core processing structure includes a loading platform 2 and a valve core processing platform which are sequentially arranged along a straight line. The loading platform 2 is connected to the tail end of the loading structure. The valve core in the loading structure first enters the loading platform 2. At the same time, a sensor is provided on one side of the loading platform 2. Under the action of the sensor, on the one hand, it can identify whether the valve core is in a suitable position on the loading platform 2, and on the other hand, it can promote the transfer of the valve core processing platform and the valve core placed on the loading platform 2.

[0026] A plurality of clamps are slidably connected to the frame 1, and the clamps are used in conjunction with the loading platform 2 and the valve core processing platform. The clamps clamp the valve core, and at the same time, the cylinder fixed to the clamps drives the valve core to move toward the valve core processing platform.

[0027] The valve core processing station includes a support plate 3 fixedly connected to the frame 1, and valve core rotating stations are arranged in sequence along the length direction of the support plate 3. The valve core rotating station rotates the valve core so that the position to be drilled is located directly opposite the punching structure. The valve core punching station punches holes in the valve core, and the valve core deburring station deburrs and grinds the punched valve core to make the outer edge surface of the valve core smoother.

[0028] The valve core rotation station, valve core punching station and valve core deburring station all include a valve core placement hole 4 opened on the support plate 3 for placing the valve core, and the valve core placement hole 4 is used to position and guide the valve core, wherein the valve core placement hole 4 located at the valve core rotation station does not limit the rotation of the valve core, and the lower side of the valve core placement hole 4 located at the valve core punching station and the valve core deburring station is provided with a bayonet used in conjunction with the valve core placement hole 4 for limiting the lower part of the valve core.

[0029] The valve core rotation station also includes a rotating shaft 6 located below the valve core placement hole 4 and rotatably connected to the frame 1 via a rotating cylinder 5. A rotation auxiliary hole 7 connected to the valve core placement hole 4 is provided on the rotating shaft 6. The lower end of the valve core is inserted into the rotation auxiliary hole 7, and the rotation auxiliary hole 7 limits the lower end of the valve core.

[0030] The valve core punching station also includes a positioning plate 8 fixedly connected to the support plate 3 and used in conjunction with the punching structure. The positioning plate 8 is provided with a positioning hole 9, which positions the punching structure so that the punching structure can punch the valve core more accurately.

[0031] The valve core deburring station also includes a blowing pump 11 slidably connected to the frame 1 via a lifting cylinder 10. The lifting cylinder 10 drives the blowing pump 11 to move up and down, thereby removing the burrs on the valve core.

[0032] The plurality of clamps are fixedly mounted on a fixed plate 12, the fixed plate 12 is slidably connected to the frame 1 via an upper and lower cylinder 13, the upper and lower cylinders 13 are slidably connected to the frame 1 via a transverse cylinder 14, the upper and lower cylinders 13 drive the clamps to move up and down, and the transverse cylinder 14 drives the clamps to move left and right.

[0033] The clamping jaws include a clamping cylinder 15 fixedly connected to a fixing plate 12, and clamping plates 16 arranged at two output ends of the clamping cylinder 15. Clamping grooves 17 for accommodating the valve core are provided on opposite surfaces of the two clamping plates 16. The valve core is further clamped and fixed under the action of the clamping grooves 17.

[0034] The punching structure includes a punching motor 19 slidably connected to the frame 1 via a driving cylinder 18 , and the driving cylinder 18 drives the punching motor 19 to approach and move away from the valve core.

[0035] A downward-inclined blanking plate 20 is provided on one side of the valve core processing structure, and the extreme position of the transverse cylinder 14 is used in conjunction with the blanking plate 20. When the valve core is polished, the outermost clamping claws away from the loading structure clamp the valve core, and the valve core is moved under the action of the transverse cylinder 14, so that the valve core is located directly above the blanking plate 20. Under the action of gravity, the valve core falls on the blanking plate 20 and slides down from the blanking plate 20.

[0036] When the utility model is used, the feeding structure is started. Under the action of the feeding structure, the original material of the valve core is moved from the feeding structure to the feeding platform 2. Under the action of the sensor at the feeding platform 2, the upper and lower cylinders 13 are started to drive the clamping claws to move downward to a suitable position. At this time, the valve core is located in the clamping groove 17. Under the action of the clamping cylinder 15, the valve core is clamped. The upper and lower cylinders 13 drive the valve core to move upward to a suitable position. Under the action of the transverse cylinder 14, the clamping claws move the valve core to the valve core rotation position.

[0037] At the valve core rotation station, the valve core falls into the valve core placement hole 4, and at the same time, the lower end of the valve core is inserted into the rotation auxiliary hole 7 on the rotating shaft 6. The rotating cylinder 5 drives the valve core to rotate a certain angle via the rotating shaft 6. When the valve core rotates driven by the rotating shaft 6, the clamping claw returns to the position directly above the loading platform 2, and the clamping claw repeats the above action to clamp the valve core. At the same time, the clamping claw at the valve core rotation station falls to synchronously clamp the valve core.

[0038] Under the action of the lateral movement cylinder 14, the valve core at the loading platform 2 moves to the valve core rotation station, and the valve core at the valve core rotation station moves to the valve core drilling station, and the drilling motor 19 is driven to move under the action of the driving cylinder 18, and the drill bit of the drilling motor 19 is inserted into the positioning hole 9 to drill the valve core;

[0039] Similarly, the clamp located at the valve core rotating station will return to the initial position after placing the valve core at the valve core punching station. After the punching is completed, the clamp located directly above the valve core punching station transfers the valve core to the valve core deburring station.

[0040] Under the action of the lifting cylinder 10, the blowing pump 11 is driven to approach the valve core and deburr and grind the valve core. Similarly, the clamp located at the valve core punching station places the valve core at the valve core deburring station and then returns to its initial position. After the deburring is completed, the clamp located directly above the valve core deburring station moves the valve core to above the blanking plate 20, and the valve core falls on the blanking plate 20 under the action of its own gravity. At the same time, the valve core falls for collection when the blanking plate 20 is tilted.
