[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: a guide pillar for engine die stamping, comprising a guide sleeve, the guide sleeve is slidably connected with a guide pillar at the bottom end, the guide pillar is provided with a connecting structure on the outer wall, and the guide sleeve and the guide pillar are both made of bronze alloy mechanism.
[0006] The connecting structure comprises a connecting ring slidably connected to the outer wall of the guide pillar, the outer wall of the connecting ring is provided with a thread, and the outer wall of the connecting ring is provided with a rotating assembly.
[0007] In order to achieve the effect that the connecting ring and the guide sleeve are connected with higher precision, preferably, the thread profile on the surface of the connecting ring is set as an isosceles trapezoid, a groove is formed at the bottom end of the guide sleeve, and a threaded hole matched with the thread on the surface of the connecting ring is arranged in the groove.
[0008] In order to achieve the effect that the guide sleeve can still slide after being connected with the connecting ring, preferably, an insertion slot is formed at the top end of the connecting ring, and the guide sleeve is inserted into the insertion slot.
[0009] In order to achieve the effect of connecting the auxiliary connecting structure with the guide sleeve, preferably, the rotating assembly comprises a rotating ring arranged on the outer wall of the connecting ring, a plurality of fixed rods are fixedly connected to one side of the rotating ring, and one end of the fixed rod is fixedly connected with the outer wall of the connecting ring.
[0010] To achieve better fixation of the rotating ring and the connecting structure, and to make it safer and more convenient to rotate, preferably, the number of fixing rods is set to four, and the fixing rods are arranged in a ring array with the connecting ring as the axis, and the surface of the rotating ring is provided with a rubber sleeve.
[0011] In order to ensure that the connection structure, whether disconnected or still connected to the guide sleeve after installation, has no impact on the stamping process, the connecting ring is preferably made of bronze alloy, and the height of the connecting ring must be lower than the height of the pressing die.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] By setting up a connection structure, when connecting the guide sleeve and the guide post, one end of the connecting ring with the threaded end is connected to the guide sleeve, while the other end is still set on the guide post. This makes the operation simple and facilitates the installation and disassembly of the equipment, saving a lot of calibration time.
[0014] By incorporating threads, rotating components, slots, and rubber rings, and by designing the threads as isosceles trapezoids, which can withstand larger loads and achieve higher thread precision, the equipment can fit snugly. The rotating ring, with its rubber ring, facilitates the connection between the connecting structure and the guide sleeve. This connection saves operation time and enhances safety. The slot design facilitates the connection between the guide sleeve and the rotating component while maintaining a large contact area between the guide sleeve and the guide post, allowing for continued sliding.
