Description

Technical Field

[0001] The utility model relates to the technical field of valve core processing, in particular to an automatic loading valve core punching internal hexagonal device. Background Art

[0002] Valve cores, also known as "airtight cores," are primarily used for tire air intake and leak prevention. CNC punching machines are currently the most commonly used devices for punching hexagonal valve cores, while vibrating plates combined with feeders are the most commonly used automated loading mechanisms for valve cores.

[0003] Since the CNC punching machine directly punches the valve core in the feeder, the valve core is positioned entirely by the feeder during this process. When the valve core is offset or tilted, this will not only cause the inner hexagonal structure of the valve core to deviate from the preset position, but the valve core can also easily damage the feeder under the extrusion of the CNC punching machine.

[0004] Therefore, an automatic loading valve core punching inner hexagonal device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to provide an automatic loading valve core punching hexagonal device in order to solve the above problems, thereby improving the problem that the existing valve core punching hexagonal device with automatic loading function is difficult to stably punch the valve core body.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions, which are a valve core punching internal hexagonal device with automatic loading, including: a supporting plate, the interior of which is fixedly connected to a servo motor, the output end of which is fixedly connected to a material stripping plate, the surface of which is provided with material stripping grooves distributed in an annular shape; a locking mechanism, which is fixedly connected to the bottom of the material stripping plate, and the bottom of the locking mechanism is fixedly connected to the supporting plate.

[0007] Preferably, the locking mechanism includes an arc plate and evenly distributed clamping components, the arc plate is fixedly connected to the inner bottom wall of the supporting plate, the clamping component is fixedly connected to the bottom of the feed plate, the clamping component coincides with the axial center line of the adjacent feed groove, and one end of part of the clamping component is in contact with the arc plate. The locking mechanism can be centered and locked in the feed groove before the valve core body is stamped, which can ensure that the valve core body is always in a vertical state during the stamping process to prevent the valve core body from being positionally shifted or tilted during stamping, so as to improve the quality of the inner hexagonal punching of the valve core body, and can unlock itself and staggered with the feed groove after the stamping is completed. At this time, there will be no obstruction in the process of the valve core body entering the feed groove, so as to ensure that the valve core body can be discharged or pushed in normally.

[0008] Preferably, the clamping assembly in contact with the arc plate includes a mounting frame fixedly connected to the bottom of the feed plate, the internal rotation of the mounting frame is connected to a gear, the bottom of the gear is meshed with a rack in contact with the arc plate, the inner side of the gear is fixedly connected to a bidirectional lead screw, the two opposite threaded surfaces of the bidirectional lead screw are threadedly connected to clamping plates, the two clamping plates are symmetrically distributed on both sides of the axial center line of the adjacent feed slots, a spring is arranged between the rack and the mounting frame, and the spring is always in a compressed state.

[0009] Preferably, clamping grooves are provided at opposite ends of two adjacent clamping plates, and the horizontal cross-section of the clamping grooves is arc-shaped, which can increase the contact area between the clamping plates and the valve core body, thereby improving the clamping effect on the valve core body.

[0010] Preferably, a reserved groove is provided at the other end of the rack, and one end of the spring contacts the inner wall of the reserved groove, which can prevent the spring from being damaged due to excessive squeezing, thereby ensuring that the spring can operate normally.

[0011] Preferably, the horizontal cross-section of one end of the rack is in the shape of an arc, which can reduce the probability of the rack and the arc plate being stuck together, thereby ensuring that the arc plate can normally push against the rack.

[0012] Preferably, both ends of the mounting frame are fixedly connected with guide columns, one end of the guide column extends to the outside of the clamping plate, and the guide column is parallel to the bidirectional screw, which can prevent the clamping plate from rotating with the bidirectional screw to ensure that the clamping plate can move horizontally.

[0013] The beneficial effects of the utility model are:

[0014] The locking mechanism can be locked in the center of the feed slot before the valve core is stamped, which can ensure that the valve core is always in a vertical state during the stamping process to prevent the valve core from being displaced or tilted during stamping, so as to improve the quality of the hexagonal inner punching of the valve core. After the stamping is completed, it can unlock itself and be staggered with the feed slot. At this time, there will be no obstruction when the valve core enters the feed slot, so as to ensure that the valve core can be discharged or pushed in normally. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] When implementing: Figure 1-6 As shown, an automatic loading valve core punching hexagonal device includes: a carrier plate 1, a servo motor 2 is fixedly connected to the interior of the carrier plate 1, an output end of the servo motor 2 is fixedly connected to a material stripping plate 3, and a surface of the material stripping plate 3 is provided with an annularly distributed material stripping groove 31; a locking mechanism 4, the locking mechanism 4 is fixedly connected to the bottom of the material stripping plate 3, and the bottom of the locking mechanism 4 is fixedly connected to the carrier plate 1;

[0024] The surface of the carrier plate 1 is provided with a feed port and a discharge port opposite to the adjacent feed slot 31, a vibration plate is provided on the outside of the feed port, and a conveyor belt is provided below the discharge port. A CNC hydraulic press is provided on the outside of the carrier plate 1, and a stamping die is fixedly connected to the output end of the CNC hydraulic press. One of the feed slots 31 opposite to the arc surface of the arc plate 41 coincides with the axis of the stamping die. The stamping die needs to be customized according to the processing requirements of the valve core body. The specific shape, material and structure need to be selected according to the actual situation, which will not be described in detail here.

[0025] After the vibration plate vibrates and transports the valve core body to the inside of the feed port in sequence, when the feed slot 31 is just connected to the feed port, the valve core body can be pushed into the feed slot 31, and at the same time, the servo motor 2 drives the feed plate 3 to rotate in steps at a specified angle, and the feed plate 3 drives all the valve core bodies in contact with it to rotate at a specified angle through the feed slot 31. When the valve core body just moves to the bottom of the stamping die, the CNC hydraulic press drives the stamping die to quickly punch the valve core body downward until the top surface of the valve core body is punched out of the inner hexagonal structure, and then the servo motor 2 continues to drive all the valve core bodies to rotate at a specified angle through the feed plate 3 and the feed slot 31. At this time, the valve core body that has been processed and entered the discharge port just loses its obstruction and falls to the top of the conveyor belt, and the conveyor belt can transport the processed valve core body away.

[0026] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the locking mechanism 4 includes an arc plate 41 and evenly distributed clamping components 42, the arc plate 41 is fixedly connected to the inner bottom wall of the carrier plate 1, the clamping component 42 is fixedly connected to the bottom of the material stripping plate 3, the clamping component 42 coincides with the axial center line of the adjacent material stripping groove 31, and one end of part of the clamping component 42 is in contact with the arc plate 41; the clamping component 42 in contact with the arc plate 41 includes a mounting frame 421 fixedly connected to the bottom of the material stripping plate 3, the internal rotation of the mounting frame 421 is connected to a gear 422, the bottom of the gear 422 is meshed with a rack 423 in contact with the arc plate 41, the inner side of the gear 422 is fixedly connected to a bidirectional lead screw 424, and the two oppositely threaded surfaces of the bidirectional lead screw 424 are both threadedly connected to the clamping plate 425, the two clamping plates 425 are symmetrically distributed on both sides of the axis of the adjacent material feeding groove 31; the opposite ends of the two adjacent clamping plates 425 are provided with clamping grooves 4251, and the horizontal cross-section of the clamping grooves 4251 is in the shape of a circular arc; a spring 426 is provided between the rack 423 and the mounting frame 421, and the spring 426 is always in a compressed state; the other end of the rack 423 is provided with a reserved groove 4231, and one end of the spring 426 contacts the inner wall of the reserved groove 4231; the horizontal cross-section of one end of the rack 423 is in the shape of a circular arc; both ends of the mounting frame 421 are fixedly connected to a guide column 427, one end of the guide column 427 extends to the outside of the clamping plate 425, and the guide column 427 is parallel to the bidirectional screw 424;

[0027] After the rack 423 in the clamping assembly 42 is separated from the arc plate 41, the spring 426 loses its obstruction, and the spring 426 pushes the rack 423 to move back quickly, and the rack 423 drives the gear 422 to rotate, and the gear 422 drives the bidirectional screw 424 to rotate, and the bidirectional screw 424 drives the two clamping plates 425 to move back to each other through two opposite threads until the solid clamping plate 425 is reset and offset from the material slot 31. At this time, there will be no obstruction in the process of the valve core body entering the material slot 31, so as to ensure that the valve core body can be discharged or pushed in normally.

[0028] When the present invention is in use, the rotation of the stripper plate 3 drives all the clamping assemblies 42 to rotate at the same time. Before the valve core passes directly under the stamping die, when the rack 423 in the clamping assembly 42 contacts the arc surface of the arc plate 41, during the subsequent rotation of the clamping assembly 42, the rack 423 is squeezed by the arc surface of the arc plate 41 toward the inside of the mounting frame 421, and the rack 423 drives the gear 422 to rotate, and the gear 422 drives the bidirectional lead screw 424 to rotate, and the bidirectional lead screw 424 drives the two clamping plates 425 to move toward each other at the same time through two opposite threads until the two clamping plates 425 clamp the valve core in the center. This can ensure that the valve core is always in a vertical state during the stamping process, so as to prevent the valve core from being offset or tilted during stamping, so as to improve the quality of punching the inner hexagon of the valve core.

[0029] It should be noted that the servo motor 2, vibration plate, conveyor belt and CNC hydraulic press in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the servo motor 2, vibration plate, conveyor belt and CNC hydraulic press can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
