Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically a positioning device for coating of automotive stamping dies. Background Technology

[0002] Automotive parts stamping dies are a type of continuous, integrated tool used to rapidly form automotive parts (such as doors, hoods, chassis brackets, etc.) from metal sheets (such as steel plates and aluminum plates) under high pressure before spraying coatings, thus achieving integrated stamping and spraying of parts.

[0003] For example, Chinese Patent Application No. 202220623474.1 discloses an automotive parts stamping die, including a base. A mounting plate is fixedly installed on the top surface of the base. A lower fixed die is provided on the top surface of the mounting plate. A stamping cavity is formed on the top surface of the lower fixed die. Multiple sliding grooves are formed on the top surface of the lower fixed die, and sliders are slidably connected inside each of the multiple sliding grooves. A connecting plate is fixedly installed on the top surface of the slider. A movable cavity is formed on the top surface of the connecting plate. The user first places the automotive parts to be stamped onto the lower fixed die, and then activates an electric telescopic rod. The electric telescopic rod drives the slider forward. The forward movement of the slider facilitates the fixing block to secure the automotive parts inside the lower fixed die, minimizing the risk of displacement of the automotive parts under impact during stamping, thereby improving the accuracy of part processing.

[0004] In automotive parts manufacturing, metal sheets are typically stamped into the desired shape using stamping dies, and then a protective or functional coating is applied to the surface of the parts. However, existing stamping dies lack independent emergency positioning and safety protection devices during operation. If an operator's limb accidentally enters the stamping area, the die cannot be positioned and stopped in time, which can easily lead to serious personal injury accidents.

[0005] Therefore, it is necessary to redesign and modify the positioning device used for coating automotive stamping dies to effectively prevent personnel injuries. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a positioning device for coating of automotive stamping dies, which has the advantages of being easy to use and solves the problem of personnel injury.

[0008] As a preferred embodiment of this utility model, the drive mechanism includes a dual-axis motor fixedly connected to the upper side of the base, with worm gears fixedly connected to the left and right output shafts of the dual-axis motor, a worm wheel meshing with the lower side of the worm gear, the inner wall of the worm wheel being fixedly connected to the surface of the round rod, and a stabilizing component provided on the upper side of the base.

[0009] As a preferred embodiment of this utility model, the stabilizing component includes a sliding rod fixedly connected to the outside of the flip plate, a stabilizing plate fixedly connected to the upper side of the base, and a groove formed on the surface of the stabilizing plate, the inner wall of the groove being slidably connected to the surface of the sliding rod.

[0010] In a preferred embodiment of this invention, a limiting ring is fixedly connected to the surface of the sliding rod, and the inner side of the limiting ring is slidably connected to the outer side of the stabilizing plate.

[0011] As a preferred embodiment of this utility model, a protective box is provided on the upper side of the dual-axis motor, and the lower side of the protective box is fixedly connected to the upper side of the base.

[0012] In a preferred embodiment of this invention, the surface of the worm gear is movably connected to a support frame via a bearing, and the lower side of the support frame is fixedly connected to the upper side of the base.

[0023] refer to Figure 4The drive mechanism includes a dual-axis motor 9 fixedly connected to the upper side of the base 3. The output shafts on the left and right sides of the dual-axis motor 9 are fixedly connected to worm gears 10. A worm wheel 11 meshes with the lower side of the worm gear 10. The inner wall of the worm wheel 11 is fixedly connected to the surface of the round rod 5. A stabilizing component is provided on the upper side of the base 3.

[0024] As a technical optimization of this utility model, by setting a driving mechanism, the worm gears 10 on both sides can be driven simultaneously, so that the flipping plates 6 on both sides move synchronously, ensuring the stability and consistency of the flipping positioning; the meshing transmission between the worm gear 10 and the worm wheel 11 has self-locking property, and can be reliably positioned after the flipping plate 6 is flipped into place, preventing accidental movement due to external force, and further enhancing the safety of the device.

[0025] refer to Figure 3 The stabilizing component includes a sliding rod 12 fixedly connected to the outside of the flip plate 6, and a stabilizing plate 13 fixedly connected to the upper side of the base 3. A groove 14 is provided on the surface of the stabilizing plate 13, and the inner wall of the groove 14 is slidably connected to the surface of the sliding rod 12.

[0026] As a technical optimization of this utility model, by setting a stabilizing component, a stable guiding effect is provided for the flipping plate 6, reducing the shaking and deviation during the flipping process, enabling the stop bar 7 to more accurately position the mold 2 pressing position, and improving the positioning accuracy and working stability of the device.

[0027] refer to Figure 3 A limit ring 15 is fixedly connected to the surface of the sliding rod 12, and the inner side of the limit ring 15 is slidably connected to the outer side of the stabilizing plate 13.

[0028] As a technical optimization of this utility model, by setting the limiting ring 15, the sliding rod 12 can be prevented from falling out when sliding in the slide groove 14, ensuring the normal operation of the stable component and enhancing the reliability and safety of the device.

[0029] refer to Figure 2 A protective box 16 is provided on the upper side of the dual-axis motor 9, and the lower side of the protective box 16 is fixedly connected to the upper side of the base 3.

[0030] As a technical optimization of this utility model, by setting the protective box 16, the dual-axis motor 9 can be effectively protected from the influence of external environmental factors, such as dust, water vapor, and collisions, thus extending the service life of the dual-axis motor 9; at the same time, it improves the stability of the device.

[0033] The working principle and usage process of this utility model: The flipping and positioning mechanism is in standby mode during normal operation. When the laser monitors 8 around the stamping device 1 detect a person's limb entering the stamping area, the drive mechanism is triggered. The dual-axis motor 9 in the drive mechanism starts, driving the worm gears 10 on both sides to rotate. The worm gears 10 mesh with the worm wheel 11, which in turn drives the round rod 5 to rotate. The round rod 5 drives the flipping plate 6 to flip, causing the stop bar 7, fixed inside the flipping plate 6 and located below the mold 2, to flip and rise urgently, accurately positioning the pressing mold 2 and preventing the mold 2 from continuing to press down and causing injury to personnel. The sliding rod 12 in the stabilizing component slides inside the groove 14 of the stabilizing plate 13, thereby increasing the flipping stability of the flipping plate 6. This effectively avoids the situation where the stamping mold 2 crushes and injures workers during the continuous production process of stamping and subsequent coating spraying, significantly improving the safety of equipment use.

[0034] In summary, during the use of this utility model, under the action of the flipping positioning mechanism, the driving mechanism and their stabilizing components, emergency positioning can be performed during the operation of the mold 2, effectively avoiding the situation where the stamping mold 2 crushes and injures the workers in the continuous production process of stamping operation and subsequent coating spraying, and significantly improving the safety of equipment use.
