DETAILED DESCRIPTION

[0040] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] As shown in the figure,

[0042] The instrument rivet assembly machine comprises a workbench 1 and a turntable 2 installed on the workbench 1, a riveting device, a reinforcement device and an object moving device. The turntable 2 is provided with instrument positioning plates 3 in a circumferential array. The instrument to be riveted is installed in the instrument positioning plate 3, and then rotated to the bottom of the riveting device through the turntable 2 to complete the riveting, and then transferred to the reinforcement device for secondary reinforcement to make it more secure, and finally moved away from the instrument positioning plate 3 through the object moving device.

[0043] The turntable 2 is operated by a cam divider, which is a mechanism for achieving intermittent motion and has the following remarkable features: high indexing accuracy, smooth operation, large torque transmission, self-locking during positioning, compact structure, small size, low noise, good high-speed performance, long service life, etc. It is an ideal product to replace traditional mechanisms such as grooved wheel mechanisms, ratchet mechanisms, incomplete gear mechanisms, and pneumatic control mechanisms.

[0044] The instrument positioning plate 3 includes a chassis and a dial limiting ring 4 installed on the chassis. A positioning block 5 and a positioning groove 6 are installed inside the chassis. A positioning bar 7 that can move up and down is installed on the positioning block 5. When installing the instrument, the positioning bar 7 passes through the holes of the dial and the movement to achieve positioning. When the riveting device is positioned, the hole of the clamping nozzle 13 is aligned with the positioning bar 7 to achieve the positioning operation. After the positioning is completed, the positioning bar 7 is lowered to complete the rivet installation and riveting work.

[0045] According to the different positions of the riveted mounting holes on the dial, the chassis can be moved, but the positioning block 5 and the positioning slot 6 remain unchanged. A No. 1 positioning hole and a No. 2 positioning hole are provided on the chassis. When the No. 1 dial is riveted, the No. 1 positioning hole corresponds to the positioning hole on the turntable 2. When the No. 2 dial is riveted, the No. 2 positioning hole corresponds to the positioning hole on the turntable 2. This operation can be achieved only by moving the chassis.

[0046] The lower end of the instrument positioning plate 3 is connected to a positioning bar 7 lifting device, and the positioning bar 7 lifting device includes a lifting bracket 8 and an adjusting block 9. The lower end of the positioning bar 7 passes through the lifting bracket 8, and the adjusting block 9 is fixedly connected to the positioning bar 7. The lifting bracket 8 is provided with a movable groove 10 for the adjustment block 9 to move. The up and down movement of the positioning bar 7 is achieved by moving the adjustment block 9 up and down.

[0047] The riveting device includes a riveting bracket 11, on which a clamping device and a lifting device for controlling the clamping device to move up and down are installed. The clamping device includes a lifting plate 12 and a clamping nozzle 13. A conveying plate 14 is installed on the side of the lifting plate 12. A No. 1 conveying channel 15 in the conveying plate 14 is penetrated by a No. 2 conveying channel 16 in the lifting plate 12. The No. 2 conveying channel 16 is arranged opposite to the inner hole of the clamping nozzle 13. The clamping nozzle 13 is movably connected to the lifting plate 12 through a connecting plate 18. A ejector pin 19 is installed above the inner hole of the clamping nozzle 13. The ejector pin 19 penetrates the No. 2 conveying channel 16 and is connected to the lifting device.

[0048] An ejector control board 20 is installed above the lifting plate 12, and the upper end of the ejector 19 is inserted into the ejector control board 20 and fixedly connected thereto, and the lower end of the ejector 19 is arranged higher than the first channel.

[0049] The clamping nozzle 13 is provided with movable holes 21 on both sides, and the movable holes 21 are connected by springs to control the opening and closing of the clamping nozzle 13.

[0050] The No. 1 conveying channel 15 is connected to the vibration plate through a connecting pipe. The rivet is conveyed to the No. 1 conveying channel 15 and then to the No. 2 conveying channel 16 through the vibration plate and finally reaches the clamping mouth 13. The ejector pin 19 moves downward to open the clamping mouth 13, and the rivet enters the holes of the dial and the movement. The ejector pin 19 performs initial riveting at the same time. When the ejector pin 19 is upward, the clamping mouth 13 is reset under the action of the spring.

[0051] The lifting device includes a No. 1 cylinder 22 and a No. 2 cylinder 23. The No. 1 cylinder 22 controls the lifting plate 12, and the No. 2 cylinder 23 controls the ejector control plate 20. The ejector control plate 20 is connected to a lowering plate 25, and the lowering plate 25 is located above the adjusting block 9. The No. 1 cylinder 22 controls the lifting plate 12 to make the clamping nozzle 13 correspond to the holes of the dial and the movement through the positioning strip 7. The No. 2 cylinder 23 controls the ejector control plate 20 to control the ejector 19 to move downward, and at the same time controls the lowering plate 25 to lower the adjusting block 9 to realize the downward movement of the positioning strip 7.

[0052] It also includes an upward adjustment device, which includes an upward adjustment cylinder 24 and an upward adjustment plate 26. The upward adjustment plate 26 is located below the adjustment block 9. A support bracket 27 is also provided on the left side of the upward adjustment device. After the upward adjustment is completed, the adjustment block 9 is prevented from moving downward during the rotation of the turntable 2. The support bracket 27 is used to keep the adjusted position and safely reach the bottom of the riveting device.

[0053] The reinforcement device includes a reinforcement cylinder 28 and a reinforcement head 29. The reinforcement cylinder 28 is connected to the reinforcement head 29 and controls its up and down movement. After the riveting device performs initial riveting, the reinforcement device performs secondary riveting to ensure the stability of the riveting.

[0054] The object moving device includes a thumb cylinder 30 and a clamp 31. The thumb cylinder 30 is connected to the clamp 31 and controls its opening and closing. A positioning device is installed below the object moving device. The positioning device includes a positioning cylinder 32 and a positioning rod 33. The positioning rod 33 is used to correspond to the positioning hole 34 on the positioning groove 6. The upward lifting action of the positioning rod 33 makes the instrument higher than the instrument positioning plate 3, which is convenient for the clamp 31 to clamp the instrument.

[0055] A conveyor belt is installed on the side of the object moving device. The clamp 31 clamps the instrument and places it on the conveyor belt. A sensor is installed on the conveyor belt. Once the sensor senses that an instrument passes by, the staff can remove it.

[0056] Working principle: Multiple instruments to be riveted are respectively installed in the corresponding instrument positioning plates 3. The turntable 2 rotates to turn the instrument positioning plate 3 to the bottom of the riveting device. The rivet is transported to the clamping nozzle 13 through the vibration plate in the early stage. The clamping nozzle 13 is aligned with the hole to be riveted by moving the No. 1 cylinder 22. The No. 2 cylinder 23 is moved to realize the ejector 19 to detach the rivet from the clamping nozzle 13 and drop it into the riveting hole to achieve initial riveting. At the same time, the No. 2 cylinder 23 moves downward and drives the adjustment block 9 to move the positioning bar 7 downward. After the initial riveting is completed, the turntable 2 runs to the bottom of the reinforcement device for secondary riveting to make the riveting more stable. Finally, it reaches the bottom of the object moving device and lifts the instrument upward through the jacking device to facilitate the object moving device to clamp and take it away from the instrument. The turntable 2 runs again to move the downward adjustment block 9 upward through the upward adjustment device. This is repeated to enter a new round of instrument riveting work.
