Description

Technical Field

[0001] The utility model relates to the technical field of workpiece surface grinding, in particular to a special sand belt steering mechanism for a sand belt polishing machine. Background Art

[0002] The efficient mixing performance of an extruder is primarily due to the complex and sophisticated screw element, a crucial component of the extruder. The screw element is a rotor with a specific helical shape and a rotating motion. Through the screw's rotation and interaction, it conveys, shears, mixes, and plasticizes the material. The spiral groove, the core component of the screw element, and its surface are crucial to its mixing performance. Because the spiral groove surface directly contacts the material during operation, it must withstand both abrasion and corrosion. Therefore, materials with high hardness, high wear resistance, and high corrosion resistance are required to extend the screw element's service life. Currently, due to the product's specific usage, the spiral groove surface of such parts can only be polished manually, which is inefficient and produces suboptimal results. Summary of the Invention

[0015] A special sanding belt steering mechanism for a sanding belt polisher comprises a sanding belt steering mechanism 1, a connecting support mechanism 2 and a sanding belt polisher 3.

[0016] The sanding belt steering mechanism includes a gear plate 1-1, a gear 1-2, a guide sleeve 1-3, a retaining ring 1-4, a shaft 1-5, a long shaft 1-6, a handwheel 1-7, a support 1-8, and a rotating seat 1-9. The support 1-8 is connected to the fixed plate 2-1, and the rotating seat 1-9 is placed inside the support 1-8. The guide sleeve 1-3 is tightened on the rotating seat 1-9 by the retaining ring 1-4 and the shaft 1-5. The sanding belt passes through the guide sleeve 1-3, and the sanding belt grinding angle is changed by the guide sleeve 1-3. The gear plate 1-1 and the rotating seat 1-9 are tightened by screws on the outside of the rotating seat 1-9. The gear 1-2 is connected to the gear plate 1-1 in a coordinated manner, and the two are meshed. The two gears 1-2 are connected by the long shaft 1-6 in the middle. The angle of the gear 1-2 is adjusted by the handwheel 1-7 at one end, and the gear plate 1-1 rotates accordingly, thereby driving the rotating seat 1-9 to rotate, thereby achieving the requirement of changing the sanding belt grinding angle.

[0017] The connecting support mechanism includes a fixing plate 2-1, a clamping plate 2-2, screws a2-3, and screws b2-4. The fixing plate 2-1 and clamping plate 2-2 are secured to the frame of the belt polisher 3 via screws b2-4. The support 1-8 is secured to the fixing plate 2-1 via screws a2-3. Screws a2-3 are GB-T70.1-2000 M12×30, and screws b2-4 are GB-T70.1-2000 M12×70.

[0018] like Figure 1 As shown, this embodiment provides a belt steering mechanism for a belt polisher, comprising a belt steering mechanism, a connecting support mechanism, and a belt polisher. The entire mechanism enables a handwheel 1-7 to drive a long shaft 1-6 to perform circular motion, i.e., the long shaft 1-6 rotates around axis Z1, and the gear 1-2 rotates around Z1 along with the long shaft 1-6. The gear 1-2 and the gear plate 1-1 engage with each other through teeth, driving the gear plate 1-1 to rotate around axis Z2. The gear plate 1-1 and the rotating seat 1-9 are tightened by screws, and the rotating seat 1-9 rotates synchronously with the gear plate 1-1. After the guide sleeve 1-3, the retaining ring 1-4, the shaft 1-5, and the rotating seat 1-9 are assembled, they rotate synchronously with the rotating seat 1-9. The abrasive belt passes through the guide sleeve 1-3 and rotates synchronously with the guide sleeve 1-3, thereby realizing rotation adjustment of the abrasive belt working surface.

[0019] The mechanism is expected to be used in the surface polishing of the company's spiral component parts, increasing efficiency by at least 50%, while also improving the overall surface quality of the parts and ensuring texture consistency.
