[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] See Figures 1-4 This embodiment provides a positioning fixture for plate-shaped parts, including a positioning plate 10. The positioning plate 10 is provided with multiple positioning units for simultaneously positioning multiple parts. In this embodiment, four sets of positioning units are provided, so that four sets of parts can be placed at the same time. Each positioning unit includes a support block 11, two sets of positioning pins 12, a first support column 13 and a second support column 14 arranged sequentially from one end of the positioning plate to the other end. The position, shape and quantity of the support block, positioning pins, first support column and second support column are determined according to the shape and size of the parts. Therefore, they are all installed on the positioning plate 10 in a detachable manner.
[0022] The part supported by the support block 11 is the riveting position. Therefore, a material channel 111 is opened downward along the top of the support block 11. A positioning sleeve 15 is provided on the positioning plate 10. The bottom end of the positioning sleeve 15 extends to the bottom of the positioning plate, and the top end of the positioning sleeve 15 is connected to the material channel 111.
[0023] The support block 11 has an installation space 112. Limiting plates 16 are respectively installed in the installation spaces 112 on both sides of the material channel 111 near the top outlet of the material channel 111. The limiting plates 16 are rotatably connected to the support block. The limiting plates 16 have an installation groove 161. A spring 17 is installed in the installation groove 161. Limiting screws 18 are installed on the side wall of the support block 11. The limiting screws 18 abut against the spring 17.
[0024] More specifically, the limiting plate 16 includes a rotating part 162 and a limiting part 163. The bottom end of the rotating part 162 is provided with a pin hole 164. A pin is provided in the pin hole 164 to form a rotatable connection with the support block. The limiting part 163 is inclined relative to the rotating part, and at least a part of the top end of the limiting part is located in the material channel 111.
[0025] After the part is placed on the positioning plate 10, the rivet enters the material channel 111 from the positioning sleeve 15, and then continues to rise and pass through the top of the limiting plate 16 until it is in the inner hole of the part. The limiting part 163 is squeezed and rotates on both sides during the rising process of the part. Finally, under the action of the spring 17, the limiting plate is reset to the material channel, which at the same time forms a support for the rivet and ensures that the rivet will not fall off.
[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
