[0021] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0022] like Figures 1-4 As shown, an umbrella rib riveting machine includes a frame 1, a riveting machine body 2 disposed on the frame 1, and a working plate 3 disposed on the frame 1 for placing umbrella ribs. The working plate 3 is provided with at least one set of fixing devices for fixing two umbrella ribs. A rotating device is also provided between the working plate 3 and the riveting machine body 2 for driving the working plate 3 to rotate at a certain angle so as to cooperate with the riveting machine body 2 and the fixing devices to rivet the umbrella ribs.

[0023] In order to ensure that the central axis of the rivet hole is located at the central axis of the fixing rod 4 after the umbrella rib is fixed, thereby improving the yield and processing accuracy, the fixing device includes: a fixing rod 4 set on the working plate 3, wherein the size of the fixing rod 4 is smaller than the inner diameter of the rivet hole on the umbrella rib; a collar 5 that can slide up and down on the fixing rod 4 through an elastic sliding device and matches the inner diameter of the rivet hole for positioning the umbrella rib and can slide down when pressed.

[0024] In order to allow the rivet to unfold more smoothly to the circumferential side and be fixed in the rivet hole, a guide chamfer 6 is also provided on the outer side of the collar 5 to assist the rivet to unfold to the circumferential side when it is pressed.

[0025] In order for the collar 5 to slide downwards under pressure to make room for the rivet to pass through, the elastic sliding device includes: a sliding hole 7 on the working plate 3 and located around the fixed rod 4, which matches the size of the collar 5; and a spring 8 with one end set at the bottom of the sliding hole 7 and the other end connected to the collar 5 to drive the collar 5 to slide upwards.

[0026] To prevent the pressure from the rivet spreading out when it is pressed to the bottom from directly affecting the lifespan of the spring 8, a limiting device is provided between the collar 5 and the working disc 3 to extend the lifespan of the elastic sliding device and enhance the riveting stability. The limiting device includes: several limiting blocks 9 set on the collar 5 and a limiting groove 10 opened on the working disc 3, which is connected to the sliding hole 7 and has a depth less than the sliding hole 7, for engaging with the limiting blocks 9 when the collar 5 slides down to the predetermined position.

[0027] To prevent the umbrella ribs from being flung apart during rotation after installation and affecting the installation of other umbrella ribs, the working plate 3 is also provided with a placement device to prevent the umbrella ribs from spreading out after installation on the fixing device and affecting the installation of other umbrella ribs. The placement device includes: a placement groove 11 on the working plate 3 that matches the fixing device and the width of the umbrella ribs; a pick-up and put-down hole 12 on the placement groove 11 for quick pick-up and put-down by the user; and at least two pads 13 in the placement groove 11 to raise the umbrella ribs to a certain height so as to prevent the rivets from colliding with the umbrella ribs when they are unfolded.

[0028] In order to drive the working disc 3 to rotate and cooperate with the riveting machine body 2, the rotating device includes: a bearing seat 14 disposed on the frame 1, the working disc 3 disposed on the bearing seat 14, and a driving device for rotating the working disc 3 to a predetermined angle is also disposed between the working disc 3 and the frame 1. The driving device includes: a reduction motor 15 fixedly disposed on the frame 1, a first synchronous pulley 16 disposed on the rotating rod of the reduction motor 15, and a second synchronous pulley 17 disposed on the working disc 3. The first synchronous pulley 16 and the second synchronous pulley 17 are connected by a synchronous belt 18.

[0029] Working principle: When in use, place the umbrella rib on the collar 5, and then start the main body of the riveting machine. At this time, the rivet slides down and resists the collar 5, thus pressing the collar 5 downward. Due to the presence of the limiting block 9, when the collar 5 slides to the starting end of the chamfer and is flush with the bottom of the placement groove 11, the collar 5 will stop moving. At this time, the rivet and the collar 5 resist each other. After being pressed, the rivet unfolds to the circumference along the chamfer direction, thus fixing the umbrella rib. Then the reduction motor 15 rotates and drives the working plate 3 to rotate and move to the next station. The user removes the riveted umbrella rib and puts in a new umbrella rib, and this cycle continues.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
