Description

Technical Field

[0001] This invention relates to a tubular riveting machine. Background Technology

[0002] Reference Figure 1 and 2 The diagram shows the structure of the product before and after riveting. Specifically, one end of a hollow tube is pressed to give it a cap-like structure. Currently, this is done by manually hammering, which is inefficient. Others are formed by stamping with a press, but since they are not specialized equipment, production safety is poor and production capacity is low. Summary of the Invention

[0003] To address the shortcomings of the existing technology, the main objective of this invention is to overcome these deficiencies and disclose a tubular riveting machine, comprising a machine base and a rivet seat mounted on the machine base. A material ejection mechanism is disposed below the rivet seat to eject the product, and a riveting pressing mechanism is disposed above the rivet seat. A feeding mechanism for feeding the product into the rivet seat and a vibrating plate for continuously replenishing the feeding mechanism are disposed on one side of the rivet seat. A drive mechanism drives the material ejection mechanism, the riveting pressing mechanism, and the feeding mechanism.

[0004] Furthermore, the ejector mechanism includes a lifting rod, a connecting rod, an ejector pin, and a double-headed damper. One end of the lifting rod is hinged to the machine base. The connecting rod connects the lifting rod and the riveting mechanism. The double-headed damper is fixed below the machine base. The ejector pin is located at the upper end of the double-headed damper. The riveting mechanism drives the lifting rod to move upward so that the double-headed damper drives the ejector pin to eject the product from the rivet seat.

[0005] Furthermore, the feeding mechanism includes a material seat, a clamping mechanism, a slide rail, a moving block, a spring, a drive seat, and a drive block. The drive seat is fixed on the machine base, and the drive block is vertically slidably disposed on the drive seat. A drive inclined surface is provided on one side of the drive block. The drive mechanism drives the drive block to move vertically reciprocally. The moving block is horizontally slidably disposed on the machine base via the slide rail and is connected to the drive seat and the moving block via the spring. The material seat is mounted on the moving block, and the clamping mechanism clamps the workpiece.

[0006] Furthermore, the clamping mechanism includes an unlocking block, a locking plate, a positioning pin, and a compression spring. The positioning pin is disposed on one side of the material seat, and the locking plate is mounted on the positioning pin with a raised portion at one end. The compression spring is mounted on the material seat by bolts and acts on the locking plate. The unlocking block is disposed on one side of the material seat. Moving the material seat pushes the locking plate up through the unlocking block.

[0007] Furthermore, a roller is provided at the tail end of the moving block.

[0008] Furthermore, the drive mechanism includes a crankshaft, a flywheel, a motor, and a drive wheel. The drive wheel is mounted on the motor, and the flywheel is mounted on the crankshaft. The flywheel and the drive wheel are connected by a belt, and the motor drives the crankshaft to rotate.

[0009] Furthermore, the riveting mechanism includes a fixed base, a lifting block, a drive rod, and a punch. The fixed base is mounted on the machine platform, the lifting block is vertically slidably disposed on the fixed base, the punch is disposed on the lifting block, and the drive rod connects the lifting block and the drive mechanism, thereby driving the punch to press down using the drive mechanism.

[0010] Furthermore, an air nozzle is provided on one side of the rivet seat to blow the product away.

[0011] The beneficial effects achieved by this invention are as follows:

[0012] This invention achieves fully automated riveting through continuous feeding from a vibratory feeder, in conjunction with a feeding mechanism, a riveting mechanism, and a top-loading mechanism. The drive mechanism utilizes a crankshaft structure, requiring only one set of drivers to operate all mechanisms, thus saving costs. The mechanisms work together via the crankshaft, which, compared to using independent drivers for each mechanism, provides high reliability through mechanical coordination and eliminates the need for additional position sensors, significantly reducing equipment costs.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] A tubular riveting machine, such as Figure 1-5 As shown, the system includes a machine base 1 and a rivet seat 3 mounted on the machine base 1. Below the rivet seat 3 is a ejector mechanism 2 that ejects the product. Above the rivet seat 3 is a riveting mechanism 4. On one side of the rivet seat 3 is a feeding mechanism 5 that feeds the product into the rivet seat 3, and a vibrating plate 6 that continuously replenishes the feeding mechanism 5. A drive mechanism 7 drives the ejector mechanism 2, the riveting mechanism 4, and the feeding mechanism 5. The rivet seat 3 is a single block with a vertically arranged through hole that mates with the product.

[0022] like Figure 1-5 As shown, the feeding mechanism 2 includes a lifting rod 21, a connecting rod 22, a ejector pin 23, and a double-headed damper 24. One end of the lifting rod 21 is hinged to the machine base 1. The connecting rod 22 connects the lifting rod 21 and the riveting mechanism 4. The lifting rod 21 swings up and down by moving the riveting mechanism 4. The double-headed damper 24 is fixed below the machine base 1. The ejector pin 23 is installed in the through hole and connected to the upper end of the double-headed damper 24. Its lower end acts on the lifting rod 21. The lifting rod 21 swings upward to push the piston rod of the double-headed damper 24, driving the ejector pin 23 to move upward until the ejector pin 23 is flush with the rivet seat 3. When the riveting mechanism 4 presses down, the ejector pin 23 moves downward due to the restoring force of the double-headed damper 24. The product falls into the through hole and stops falling after reaching the initial position of the double-headed damper 24. At this time, the upper end of the product protrudes from the upper surface of the rivet seat 3 and is riveted into the target object by the riveting mechanism 4.

[0023] like Figure 1-5As shown, the feeding mechanism 5 includes a material base 51, a clamping mechanism 52, a slide rail 53, a moving block 54, a spring 55, a drive base 56, and a drive block 57. The drive base 56 is fixed on the machine base 1. The drive block 57 is vertically slidably mounted on the drive base 56, and a driving inclined surface and a vertical plane are provided on one side of the drive block 57. The drive mechanism 7 drives the drive block 57 to move vertically reciprocally. The moving block 54 is horizontally slidably mounted on the machine base 1 via the slide rail 53, and is connected to the drive base 56 and the moving block 54 via the spring 55, which provides a leftward pulling force to the moving block 54, ensuring that one end of the moving block is attached to the drive block 57. When the drive block 57 moves downward, the inclined surface drives the moving block 54 to move horizontally to the right. When it is on the plane, the moving block 54 remains stationary to satisfy the riveting pressure of the rivet mechanism 4 on the product. When it moves upward, the moving block 54 is attached to the drive block 57 by the pulling force of the spring 55 and moves to the left along the inclined surface. The material holder 51 is fixed on the moving block 54 to enable horizontal movement of the material holder 51. The product is temporarily fixed by the clamping mechanism 52.

[0024] like Figure 1-5 As shown, the clamping mechanism 52 includes an unlocking block 521, a locking plate 522, a positioning pin 523, and a pressure spring 524. The positioning pin 523 is located on one side of the material seat 51. The locking plate 522 is mounted on the positioning pin 523, and one end of the locking plate 522 has a raised portion 525. The pressure spring 524 is bolted to the material seat 51 and acts on the locking plate 522. The unlocking block 521 is located on one side of the material seat 51. Moving the material seat 51 causes the locking plate 522 to be raised by the unlocking block 521. When the locking plate 522 is raised, it opens the clamping part of the material seat 51. After the product is fed into the clamping part by the vibrating plate 6, the material seat 51 moves to the right, and the bridging starter 525 separates from the unlocking block 521. Under the force of the pressure spring 524, the product is clamped in the clamping part; then the product is moved to the rivet seat 3.

[0025] In one embodiment, such as Figure 1-5 As shown, a roller 58 is provided at the tail end of the moving block 54 to reduce wear between the moving block 54 and the drive block 57.

[0026] like Figure 1-5 As shown, the riveting mechanism 4 includes a fixed base 41, a lifting block 42, a drive rod 43, and a punch 44. The fixed base 41 is installed on the machine base 1. The lifting block 42 is vertically slidably arranged on the fixed base 41 and connected to the drive mechanism 7 through the drive rod 43. The punch 44 is arranged on the lifting block 42. The drive mechanism drives the punch 44 to press down, thereby realizing the riveting of the product.

[0027] like Figure 1-5As shown, the drive mechanism 7 includes a crankshaft 71, a flywheel 72, a motor 73, and a drive wheel 74. The drive wheel 74 is mounted on the motor 73, and the flywheel 72 is mounted on the crankshaft 71. The flywheel 72 and the drive wheel 74 are connected by a belt, and the motor 73 drives the crankshaft 71 to rotate. The drive distance of the mechanism is adjusted by adjusting the eccentricity of the crankshaft 71. Specifically, the drive block 57 is connected to the crankshaft 71 via a universal joint connecting rod, and the downward movement distance of the drive block 57 is controlled by adjusting the eccentricity of the crankshaft 71. For the riveting mechanism 4, the drive rod 43 is connected to the crankshaft 71, and the downward pressing distance of the punch 44 is also controlled by adjusting the eccentricity of the crankshaft 72.

[0028] In one embodiment, such as Figure 1-5 As shown, an air nozzle is provided on one side of the rivet base 3 to blow the product away. After riveting is completed, the air nozzle blows air to blow the product away from the rivet base 3.

[0029] When using this invention, as Figure 1-5 As shown, the product is poured into the vibratory feeder 6 and connected to the feed inlet on the machine base 1 via the guide tube. After the product falls into the clamping part, the flywheel 72 drives the crankshaft 71 to rotate, which controls the moving block 54 to move the material seat 51 to the right. At the same time, the lifting block 42 drives the punch 44 to descend. When the vertical plane of the driving block 57 contacts the moving block 54, the product is just above the through hole of the rivet seat 3. The punch 44 presses the product into the through hole and continues to press down to achieve riveting. The flywheel 72 continues to rotate, and the lifting block 42 moves upward, which drives the lifting rod 21 through the connecting rod 22 to push the double-headed damper 24 to drive the ejector pin 23 to push the product out. The product is then blown away through the air nozzle. At the same time, the moving block 54 moves to the left to clamp the next product, and the above operation is repeated.

[0030] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications or equivalent substitutions made to the present invention without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present invention.
