Description

Technical Field

[0001] This application relates to the field of assemblies, and particularly to a metal stamping assembly. Background Art

[0002] Metal stamping is a manufacturing process that uses a metal stamping die or a series of metal stamping dies to form a metal sheet into a workpiece with a three-dimensional dimensional shape. When the stamped workpiece is subsequently assembled, bolts are required to fix it.

[0003] For existing assemblies, most of them clamp the workpieces to be assembled by sleeving them on bolts and then using nuts. However, during the clamping process, there will be shaking between the two workpieces, and it is impossible to quickly align and position the two workpieces, resulting in the problem of reduced work efficiency. Utility Model Content

[0004] In order to achieve the above object, this application provides a metal stamping assembly.

[0005] The metal stamping assembly provided by this application adopts the following technical solution:

[0006] A metal stamping assembly includes a bolt, a first workpiece, and a second workpiece. It is characterized in that: a connecting plate is sleeved on the bolt, and the two sides of the lower surface of the connecting plate are slidably connected with vertically arranged positioning rods. Two through holes adapted to the positioning rods are opened on the upper surface of the first workpiece, and two insertion holes inserted with the positioning rods are opened on the upper surface of the second workpiece. An arc-shaped groove is opened on one side wall of the insertion hole, a receiving hole is opened at the bottom end of one side wall of the positioning rod, a spring is arranged in the receiving hole, one end of the spring is fixedly connected with the side wall of the receiving hole, the other end of the spring is fixedly connected with a spherical ball, a part of the spherical ball extends out of the receiving hole and is adapted to the arc-shaped groove, and a nut is threadedly connected below the second workpiece where the bolt is located.

[0007] By adopting the above technical solution, during use, the connecting plate is sleeved on the bolt, and then the first workpiece and the second workpiece are sleeved on the bolt in sequence, so that the positioning rods penetrate through the through holes and are inserted into the insertion holes. At the same time, when the spherical ball contacts the side wall of the insertion hole, it will squeeze the spring to retract the spherical ball into the receiving hole. After that, when the spherical ball approaches the arc-shaped groove, the spring will rebound and snap the spherical ball into the arc-shaped groove, preventing the positioning rod from naturally falling out of the insertion hole, positioning and aligning the first workpiece and the second workpiece. Then, the nut is screwed on to fix and assemble the first workpiece and the second workpiece, thus avoiding the problem of reduced work efficiency caused by the inability to quickly align and position the two workpieces.

[0008] Preferably, a fixing plate is sleeved under the bolt, and fixing rods are fixedly connected to both sides of the lower surface of the fixing plate. Locking rods are provided on both side walls of the fixing plate. The locking rods penetrate through the fixing plate and abut against the bolt, and the locking rods are threadedly connected to the fixing plate.

[0009] By adopting the above technical solution, when screwing the bolt to an object, first drill holes on both sides of the screwing part of the object, insert the fixing rods into the holes respectively to install the fixing plate at the screwing part of the object, then penetrate the bolt through the fixing plate and screw it to the object, and then rotate the locking rod to abut the locking rod against the bolt, which can prevent the bolt from rotating during use and separating from the object.

[0010] Preferably, a telescopic rod is provided inside the spring, and both ends of the telescopic rod are fixedly connected to the side wall of the receiving hole and the spherical ball respectively.

[0011] By adopting the above technical solution, the stability of the spring can be improved through the telescopic rod.

[0012] Preferably, a plurality of tooth blocks are fixedly connected to one end of the locking rod close to the bolt.

[0013] By adopting the above technical solution, the friction between the locking rod and the bolt can be increased through the tooth blocks to prevent the bolt from rotating.

[0014] Preferably, the length of the locking rod is less than the distance between the outer wall and the inner wall of the fixing plate.

[0015] By adopting the above technical solution, after the locking rod abuts against the bolt, the end of the locking rod far from the bolt will be located inside the fixing plate to prevent it from extending out.

[0016] Preferably, a receiving groove is formed on the lower surface of the bolt above the connecting plate, and the receiving groove is adapted to the connecting plate.

[0017] By adopting the above technical solution, the connecting plate can be hidden through the receiving groove.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. In this application, through the cooperation of structures such as positioning rods, springs, and balls, during use, the connecting disc is sleeved on the bolt, and then the first workpiece and the second workpiece are successively sleeved on the bolt. The positioning rod penetrates through the through-hole and is inserted into the jack. At the same time, when the ball contacts the side wall of the jack, it will squeeze the spring to retract the ball into the receiving hole. After that, when the ball approaches the arc-shaped groove, the spring will rebound and snap the ball into the arc-shaped groove, preventing the positioning rod from falling out of the jack naturally, aligning and positioning the first workpiece and the second workpiece. Then, the nut is screwed on to fix and combine the first workpiece and the second workpiece, thus avoiding the problem of being unable to quickly align and position the two workpieces, which reduces the working efficiency;

[0020] 2. When screwing the bolt onto an object, first drill holes on both sides of the screwing part of the object, insert the fixing rods into the holes respectively, install the fixing disc at the screwing part of the object, then penetrate the bolt through the fixing disc and screw it onto the object. After that, rotate the locking rod to abut the locking rod against the bolt, which can prevent the bolt from rotating and disengaging from the object during use. BRIEF DESCRIPTION OF THE DRAWINGS
