DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In this embodiment, if Figures 1-11 As shown, a fully automatic press-fitting device for simultaneous riveting and testing of multiple rivets includes a frame 100. A conveyor line for circulating and conveying pallets is provided inside the frame 100. Product tooling is placed above the pallet. The product tooling and the press-fitting main product are circulated and conveyed in the form of a conveyor line. The product tooling automatically stops after it flows to the corresponding station. The device automatically scans the pallet QR code after sensing the pallet. After the scan is successful, the tooling is located through the control panel and the press-fitting mechanism 200 to facilitate subsequent operations. The frame 100 is provided with a press-fitting mechanism 200. 0, used for riveting multiple rivets. Multiple rivets are riveted synchronously to avoid warping of product tooling, ensure consistent riveting effect, and facilitate ensuring product tooling quality. A floating pressure head structure is adopted to avoid multiple rivets being riveted simultaneously, resulting in inconsistent pressing effects. A detection mechanism 300 is provided on one side of the pressing mechanism 200 for detecting product tooling and rivets. The force-displacement curve of the product tooling is monitored in real time during the pressing process, which facilitates the detection of the product tooling height, rivet flange size and appearance, and further ensures the consistency of the product tooling;

[0031] The detection mechanism 300 includes a first lifting component 310 for lifting the product tooling during detection. The first lifting component 310 may include lifting components such as electric push rods and cylinders. A height detection component 320 is arranged above the first lifting component 310. The height detection component 320 may include components such as altimeters, sensors, laser rangefinders, etc., which are used to detect the height of the product tooling. Clamping components 330 are symmetrically arranged on both sides of the conveyor line.

The visual detection component 340 may include components such as scanners, sensors, and cameras. The visual detection component 340 is arranged above the height detection component 320. The clamping component 330 is arranged on the side of the first lifting component 310 away from the pressing mechanism 200, which is convenient for detecting the appearance and size of the product tooling.

[0032] Among them Figure 2-Figure 11 As shown, the pressing mechanism 200 includes a second lifting component 210 for lifting the product tooling during pressing, which is convenient for positioning the product tooling. A pressing component 220 is provided above the second lifting component 210, which is used to cooperate with the second lifting component 210 to realize the simultaneous riveting operation of multiple rivets. The second lifting component 210 is set at the bottom of the frame 100 to facilitate the pressing operation on the lower surface of the product tooling.

[0033] Among them Figure 2-Figure 9 As shown, the second lifting component 210 includes a first cylinder 211 fixedly connected to the frame 100, and a horizontal plate 212 is provided on the first cylinder 211. The movable end of the first cylinder 211 passes through the horizontal plate 212 and is fixedly connected to the lower pressure head 213. The outer side of the lower pressure head 213 is slidably connected to a mounting plate 214, and a plurality of second cylinders 215 are symmetrically provided on the lower surface of the mounting plate 214. The movable end of the second cylinder 215 is fixedly connected to the upper surface of the horizontal plate 212. With the mutual cooperation of the first cylinder 211 and the second cylinder 215, it is easy to drive the lower pressure head 213 to move smoothly.

The output end of the electronic press 223 passes through the support plate 222 and is fixedly connected to the upper pressing head 224. The upper pressing head 224 is driven downward by the electronic press 223 to facilitate the compaction of the product tooling.

[0035] Among them Figure 2-Figure 9As shown, the lower pressing head 213 includes a rivet seat 2131 and a lower pressing head body 2132. The lower pressing head body 2132 is arranged at the upper end of the rivet seat 2131. The upper surface of the rivet seat 2131 is provided with a plurality of grooves. A rivet ejector pin 2133 is arranged inside the groove. A spring is sleeved on the outer side of the rivet ejector pin 2133. One end of the spring is fixedly connected to the rivet ejector pin 2133. The spring enables the rivet ejector pin 2133 to automatically return to its original position. The other end of the spring is fixedly connected to the groove. The rivet ejector pin 2133 is fixedly connected to the groove. The rivet seat 2131 is slidably connected, and a placement groove 2134 is provided on the top of the lower pressure head body 2132.

The lower end of the support block 2135 is provided with a chamber for installing a floating steel ball 2136. A pad is provided on the inner wall of the chamber. The floating steel ball 2136 is embedded in the top of the lower pressure head body 2132 to adapt to the height difference of the rivet, so that the rivet is subjected to balanced force, thereby achieving a consistent press-fitting effect.

[0036] Among them Figure 1 As shown, a control panel and an alarm are provided on one side of the frame 100, and the control panel is electrically connected to the alarm. The control panel is also electrically connected to electrical components such as the height detection component 320, the clamping component 330, and the visual detection component 340, so as to facilitate the control and driving of the electrical components. The parameter data of the product tooling and the rivet are input through the control panel. When the detection mechanism 300 detects that the parameters such as the product tooling height, the flange size of the rivet, and the appearance do not meet the technical requirements, the control panel displays NG and triggers the alarm to sound an alarm, thereby avoiding the occurrence of unqualified product tooling, increasing the consistency of the product tooling, and improving production efficiency and quality.

[0037] Among them Figure 3-10 As shown, the structural dimensions of the upper pressing head 224 are consistent with those of the lower pressing head 213. Both the upper and lower pressing heads adopt a floating structure, which is convenient for automatically adapting to the height difference of the rivets and ensuring the normal operation of the equipment.

[0039] During use, in order to meet the requirements of fully automatic pressing, the product tooling is transported in the form of a conveyor line. When the product tooling flows to the corresponding position, the conveyor line stops conveying, and the second lifting component 210 automatically lifts and positions the product tooling, starts the cylinder to drive the lower pressure head 213 to extend and lock it, and starts the electronic press 223 to drive the upper pressure head 224 to press down, thereby realizing the fixed pressing operation of the product tooling. Springs and floating steel balls 2136 are provided inside the upper pressure head 224 and the lower pressure head 213 to automatically adapt to the height difference of the rivet and realize the rivet pressing operation. After the pressing process is completed, the conveyor line drives the product tooling to the position to be inspected, and the first lifting component 310, the height detection component 320, the clamping component 330 and the visual inspection component 340 are used to detect parameters such as the height of the product tooling, the size of the rivet flanging and the appearance, so as to facilitate the timely detection of defective products.
