[0027] See also Figure 1-8The utility model provides a technical solution: an oxygen sensor riveting device, comprising a riveting mechanism 1 for riveting the oxygen sensor, a base 2 for placing the oxygen sensor to be processed, and a lifting mechanism 3 for driving the base 2 to rise so that the oxygen sensor can be riveted. The base 2 is provided with a lifting column 20 fixedly connected to it at one end, and the other end of the lifting column 20 is provided with a bottom plate 21 fixedly connected to it. The lifting column 20 is also provided with a base plate 22 that is limited and slidably matched with it. The lifting mechanism 3 includes a lifting cylinder 30, and the driving end of the lifting cylinder 30 is correspondingly arranged with the bottom plate 21 up and down. When the oxygen sensor needs to be riveted, the oxygen sensor is first placed on the base 2, and then driven by the lifting cylinder 30 to support the bottom plate 21 to rise, thereby driving the base 2 to rise until the base 2 rises to the point where the oxygen sensor can be sent to the riveting mechanism 1.

[0028] The riveting mechanism 1 includes a knife seat 101 and a pressing knife 102 fixedly installed with the knife seat 101 for riveting the oxygen sensor. A rolling shaft 103 rotatably connected to the knife seat 101 is provided at one end of the knife seat 101. The riveting mechanism 1 also includes a guide rail fixture 104 for pushing the pressing knife 102 to rivet the oxygen sensor. The rolling shaft 103 rolls with the guide rail fixture 104. The riveting mechanism 1 also includes a mounting shell 11. A mounting groove 110 is provided in the mounting shell 11. The guide rail fixture 104 is fixedly installed with the mounting groove 110, and the guide rail fixture 104 is trapezoidal. A connecting block 111 is fixedly connected to the outer side of the mounting shell 11. The connecting block 111 is provided with a sliding column 12 fixedly connected to the sliding column 12 at one end. The sliding column 12 is provided with a sliding column 12 fixedly connected to the sliding column 12 at the other end. The lifting plate 13 is connected, the lifting plate 13 is provided with a connecting seat 130 fixedly connected thereto, the connecting seat 130 is provided with a driving column 14 fixedly connected thereto, the driving column 14 is provided with a driving motor 140 transmission-connected thereto, the driving motor 140 is provided with a mounting platform 141 fixedly mounted thereto, the mounting platform 141 is provided with a supporting column 142 fixedly connected thereto at one end, the supporting column 142 is provided with a supporting platform 143 fixedly connected thereto at the other end, the sliding column 12 is limitedly slidably matched with the supporting platform 143, the buckle riveting mechanism 1 also includes a buckle riveting head 15 fixedly connected to the supporting platform 143, the buckle riveting head 15 is limitedly slidably matched with the mounting shell 11, the buckle riveting head 15 is provided with a tool holder 150 fixedly connected thereto, and the tool holder 101 is slidably matched with the tool holder 150 The tool holder 150 is provided with a positioning hole 151 for the oxygen sensor to pass through, and a sleeve 152 for positioning the oxygen sensor is provided in the positioning hole 151. A spring is provided at one end of the sleeve 152 to be fixedly connected thereto, and the other end of the spring is fixedly connected to the rivet head 15. The sleeve 152 is also provided with a through hole 153 for the knife head of the press knife 102 to pass through and rivet the oxygen sensor. When the base 2 drives the oxygen sensor to push up, the oxygen sensor will extend into the sleeve 152 to position the oxygen sensor to avoid swinging when riveting it, thereby affecting the riveting accuracy. When the oxygen sensor extends into the sleeve 152, the lifting cylinder 30 will continue to drive the base 2 to rise until the sleeve 152 compresses the spring to the maximum extent. At this time, the base 2 is subjected to the lifting gas The upward lifting force of the cylinder 30 and the downward reverse thrust of the compressed spring ensure that the oxygen sensor is positioned in the sleeve 152 and will not shake due to the squeezing of the press knife 102. When the oxygen sensor is sent into the riveting mechanism 1 and positioned, the driving motor 140 drives the driving column 14 to descend, thereby driving the lifting plate 13 to descend, and then the sliding column 12 drives the mounting shell 11 to descend. At this time, the rivet head 15 is fixedly connected to the support platform 143. When the mounting shell 11 descends, the rivet head 15 is fixed relative to the support platform 143, and when the mounting shell 11 descends, it slides downward relatively. Therefore, the guide rail tooling 104 installed in the mounting shell 11 will also descend synchronously with the mounting shell 11.When the guide rail fixture 104 descends, the rolling shaft 103 installed on the tool holder 101 rolls relative to the guide rail fixture 104. Since the guide rail fixture 104 is trapezoidal in shape when viewed from the side, when the rolling shaft 103 rolls from bottom to top along the guide rail fixture 104, it pushes the tool holder 101, thereby driving the pressing knife 102 to slide inward along the tool holder 150, thereby riveting the oxygen sensor located in the middle sleeve 152 of the tool holder 150. A through hole 153 is provided on the sleeve 152 corresponding to each pressing knife 102, so that the pressing knife 102 can be inserted into the through hole 153 conveniently. The oxygen sensor is riveted by providing a rolling shaft 103 rotatably connected to one end of the tool holder 101, and the mounting shell 11 is lowered to roll the rolling shaft 103 from bottom to top along the guide rail fixture 104, so that the tool holder 101 is pushed along the tool holder 150, and the pressing knife 102 rivets the oxygen sensor. Compared with the prior art in which the tool holder 101 and the fixture slide in a fitted manner, the wear on the surface of the guide rail fixture 104 can be greatly reduced, thereby greatly improving the service life of the guide rail fixture 104, and the riveting accuracy of the oxygen sensor will not be affected by the wear of the guide rail fixture 104.

[0029] In order to be able to control the height to which the driving motor 140 drives the mounting shell 11 to descend, the lifting plate 13 is also provided with a connecting column 131 fixedly connected thereto at one end, and the connecting column 131 is provided with a position sensor 132 fixedly connected thereto for controlling the descending height of the mounting shell 11. The position sensor 132 is connected to the driving motor 140 signal. When the lifting plate 13 descends to a certain height, the position sensor 132 will contact the support platform 143, thereby sending a signal to the driving motor 140 indicating that the preset descent height has been reached, and the driving motor 140 stops driving upon receiving the signal.

[0030] The knife seat 101 is also provided with a pressure column 105 fixedly connected thereto, one end of the pressure column 105 is provided with a pressure spring 106 fixedly connected thereto, and the other end of the pressure spring 106 is against the guide rail fixture 104. When the rolling shaft 103 rolls from bottom to top along the guide rail fixture 104, the pressure spring 106 will also be compressed. When the pressure knife 102 completes riveting the oxygen sensor, the driving motor 140 drives the driving column 14 to rise, thereby driving the mounting shell 11 to rise. When the mounting shell 11 rises, At this time, the rolling shaft 103 rolls from top to bottom along the guide rail fixture 104, and the compression spring 106 will also slide from the upper end of the guide rail fixture 104 to the lower end of the guide rail fixture 104. At this time, due to the reset and rebound of the compressed compression spring 106, the tool holder 101 returns to its original position from the inside to the outside along the tool holder 150, and then the lifting cylinder 30 drives the driving end to retract, and the bottom plate 21 will also drive the base 2 to descend until the base 2 falls on the base plate 22, thereby completing the entire riveting process of the oxygen sensor.

[0031] The working principle or beneficial effect of the utility model is as follows: a rolling shaft 103 rotatably connected to one end of the tool holder 101 is provided, and the rolling shaft 103 also rolls with the guide rail fixture 104. When it is necessary to use the pressure cutter 102 to rivet the oxygen sensor, the rolling shaft 103 is used to roll along the guide rail fixture 104 from bottom to top, so that the tool holder 101 drives the pressure cutter 102 to squeeze the oxygen sensor, thereby riveting rivets on the oxygen sensor. By using the rolling shaft 103 and the guide rail fixture 104 to roll, the pressure cutter 102 rivets the oxygen sensor. Compared with the contact-fitting sliding of the prior art, the wear on the surface of the guide rail fixture 104 can be greatly reduced, thereby increasing the service life of the guide rail fixture 104, and the riveting accuracy of the oxygen sensor will not be affected by the wear of the guide rail fixture 104.

Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
