The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0030] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a positioning mechanism of a part riveting machine, comprising: a machine body 1; a riveting device 11, arranged on the top of the machine body 1, for performing riveting processing on parts; a rotating plate 12, arranged above the machine body 1; a conveying plate 13, arranged on the top of the rotating plate 12, for feeding the riveting device 11; a clamping assembly 2, arranged on both sides of the conveying plate 13, for fixing and limiting the parts on the conveying plate 13; a rotating assembly 3, arranged above the machine body 1, for driving the clamping assembly 2 to perform fixed and limit operations on the parts; a limiting assembly 4, arranged on both sides of the conveying plate 13, for controlling the directional clamping of the clamping assembly 2.

[0031] The clamping assembly 2 includes a pair of V-shaped clamping strips 21, which are slidably connected to the top of the conveying plate 13, and the sides of the pair of V-shaped clamping strips 21 that are away from each other are fixedly connected with extrusion strips 22, and the top of the conveying plate 13 is rotatably connected with a pair of eccentric blocks 23; the rotating assembly 3 includes a pair of rotating rods 31, which are rotatably connected to the top of the conveying plate 13, and the top ends of the rotating rods 31 penetrate the side walls of the eccentric blocks 23 and are fixedly connected to the eccentric blocks 23, and the bottom ends of the rotating rods 31 penetrate the side walls of the conveying plate 13 and are fixedly connected with gears 32, and the top of the body 1 The body 1 is fixed with two arcuate bars 33, and teeth 34 are arranged on one side of the arcuate bars 33 close to the rotating plate 12; the limiting assembly 4 includes two long bars 41 and two short bars 42, and the two long bars 41 and the two short bars 42 are fixed on the top of the conveying plate 13, and the side walls of the long bars 41 and the short bars 42 are provided with telescopic grooves 43 adapted to the extrusion bars 22; the top of the conveying plate 13 is provided with a placement groove 6; springs 7 are fixed between the extrusion bars 22 and the conveying plate 13; the top of the body 1 is rotatably connected with a turntable 8, and the top of the turntable 8 is fixed to the rotating plate 12.

[0032] The specific scheme is as follows: the rotating plate 12 is driven to rotate by controlling the turntable 8, and the rotating plate 12 drives the conveying plate 13 to rotate toward the riveting device 11. The conveying plate 13 drives the rotating rod 31 and the gear 32 at the bottom thereof to rotate toward the arc strip 33, so that the gear 32 is meshed and connected with the teeth 34, so that the rotating rod 31 drives the eccentric block 23 to rotate 180 degrees. Under the limiting action of the long strip 41 and the short strip 42, the eccentric block 23 pushes the extrusion strip 22 and the V-shaped clamping strip 21 to slide along the telescopic groove 43 toward the placement groove 6, so that the two V-shaped clamping strips 21 are clamped on both sides of the workpiece to prevent the workpiece from moving inside the placement groove 6. The rotating plate 12 drives the workpiece to rotate to the riveting position of the riveting device 11 through the conveying plate 13, and the workpiece on the placement groove 6 is subjected to riveting by controlling the riveting device 11. After the riveting is completed, the rotating plate 12 The conveying plate 13 is driven to rotate again, and the conveying plate 13 drives the rotating rod 31 and the gear 32 to rotate toward the other arc-shaped bar 33, so that the gear 32 is meshed with the teeth 34 on the other arc-shaped bar 33, and the rotating rod 31 drives the eccentric block 23 to rotate again, and the limit on the extrusion bar 22 is released. Under the elastic action of the spring 7 itself, the spring 7 pulls the two V-shaped clamping strips 21 to slide to the two sides of the conveying plate 13 through the extrusion bar 22, so that the V-shaped clamping strips 21 are separated from the workpiece, and the limit on the workpiece is released, which is convenient for workers to take the workpiece out of the placement groove 6. During the riveting process, the two V-shaped clamping strips 21 are set to clamp the two sides of the workpiece to limit the workpiece and prevent the workpiece from moving on the placement groove 6, so that the rivet is accurately aligned with the workpiece, and the position of the riveting point between the rivet and the workpiece is prevented from shifting, and the riveting effect is high.

[0033] Embodiment 2: Figure 4As shown, a positioning mechanism for a parts riveting press disclosed in the second embodiment of the present invention has a structure that is basically the same as that in the first embodiment, except that a rubber block 5 is fixedly connected to one side of two V-shaped clamping strips 21 that are close to each other.

[0034] The specific solution of this invention is as follows: by setting a rubber block 5, two V-shaped clamping strips 21 are clamped on both sides of the workpiece by the rubber block 5. Under the squeezing action of the V-shaped clamping strips 21 and the workpiece, the rubber block 5 is deformed to increase the clamping area between the rubber block 5 and the workpiece, thereby improving the clamping effect of the two V-shaped clamping strips 21 on the workpiece.
