Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine turntable technology, specifically a shot blasting machine turntable adjustment device. Background Technology

[0002] In modern industrial production, shot blasting machines are widely used surface treatment equipment. They use shot blasters to propel steel shot and other projectiles at high speed onto the surface of materials to remove impurities such as adhering sand, oxide scale, and rust, thereby improving the surface quality and mechanical properties of the workpiece. Rotary table shot blasting machines are particularly suitable for mass production of surface cleaning of small and medium-sized workpieces due to their advantages such as high production efficiency, good sealing effect, compact structure, and convenient loading and unloading. They play a key role in many industries such as casting, automobile manufacturing, and machining.

[0003] To address the aforementioned issue of turntable adjustment, Chinese Patent Publication No. CN223012892U discloses a turntable adjustment device for a shot blasting machine. The device includes a shot blasting machine chamber door, an X-shaped frame positioned in front of the chamber door, and a transmission assembly between the X-shaped frame and the chamber door. A guide plate is fixedly connected to the center of the front end of the chamber door, and the guide plate is inclined. Connecting pillars are slidably inserted at the four corners of the upper end of the X-shaped frame. The upper ends of the four connecting pillars are jointly fixedly connected to the turntable body, and helical springs are slidably fitted onto the outer walls of the four connecting pillars. The vibration coefficient of this turntable shot blasting machine can be increased, thereby increasing the vibration coefficient of the workpiece. This increases the contact effect between the workpiece and the shot blasting material, allowing impurities on the workpiece surface to fall off more quickly. Furthermore, impurities in the recesses of workpieces with uneven surfaces are more easily removed, reducing the processing time.

[0004] The above solution proposes a combination of helical springs and trapezoidal blocks to increase the contact effect between the workpiece and the shot blasting material, allowing impurities on the workpiece surface to fall off more quickly. However, the turntable in the above solution lacks protective measures during processing. During shot blasting, high-speed shot continuously impacts the workpiece surface, and inevitably causes splashing impact on the edge of the turntable. Long-term use can easily lead to wear and deformation of the turntable, and even jamming due to shot accumulation. Therefore, we provide a shot blasting machine turntable adjustment device.

A right-angled trapezoidal snap-fit ​​plate is fixedly connected to the side of the pull rod near the storage cylinder.

[0007] In some embodiments, the slot is connected to the storage slot, the size of the storage slot is the same as the size of the fixed cone block and the movable cone block, and the fixed cone block and the movable cone block are arranged in opposite directions.

[0008] In some embodiments, the fixed conical block is slidably connected to the storage groove, and the inclined surface of the right-angled trapezoidal snap-fit ​​plate faces downward.

[0009] In some embodiments, a mounting groove is fixedly provided on the top of the turntable, an electromagnet is fixedly connected to the bottom of the mounting groove, a placement platform is provided inside the mounting groove, and a metal plate is fixedly connected to the bottom of the placement platform.

[0010] In some embodiments, the placement platform is slidably connected to the mounting groove, the metal plate is magnetically connected to the electromagnet, and the electromagnet is electrically connected to an external power supply.

[0012] In some embodiments, the motor output end is fixedly connected to the center of the bottom of the turntable, and the mounting bracket is fixedly connected to the shot blasting machine door via a mounting plate.

[0013] This utility model has at least the following beneficial effects: This invention utilizes a snap-fit ​​mechanism to enclose the turntable with several arc-shaped protective plates on its outer side, providing protection. The conical shape of these plates also facilitates the drop of projectiles, preventing accumulation. When the arc-shaped protective plates become worn and deformed due to prolonged impact from projectiles, the operator can stop the shot blasting machine, press the damaged plate downwards, and allow a right-angled trapezoidal snap-fit ​​plate to slide past the movable conical block to its bottom. Then, the damaged plate is lifted upwards. With the cooperation of the movable and fixed conical blocks, the right-angled trapezoidal snap-fit ​​plate can slide directly out from the side of the fixed conical block, enabling quick disassembly and reassembly of the arc-shaped protective plates. During installation, a new arc-shaped protective plate can be easily inserted, preventing continuous impact of high-speed projectiles on the turntable edge and avoiding wear and deformation after prolonged use. This also ensures better projectile drop, preventing accumulation and jamming. Attached Figure Description
