Description

Technical Field

[0001] This invention belongs to the field of helmet mold technology, and specifically relates to a surface deburring device for helmet mold manufacturing. Background Technology

[0002] A helmet is a piece of equipment that protects the head. It is usually semi-circular and mainly consists of three parts: an outer shell, a liner, and a suspension system. The outer shell is made of materials such as special steel, fiberglass, reinforced plastic, leather, and nylon.

[0003] Existing helmet molds often rely on files, chamfering knives, or other electric deburring tools to remove burrs. Using files or chamfering knives to remove burrs is too physically demanding, while using electric deburring devices is more likely to create grooves on the surface of the grinding wheel or sanding belt, which will reduce the burr removal effect. Uneven load on the grinding wheel or sanding belt will also reduce its service life. Summary of the Invention

[0015] The flexible angle retaining component can prevent the grinding wheel and the edge of the mold from making hard contact, thereby achieving a better burr removal effect and avoiding the risk of the high-speed rotating grinding wheel damaging the mold;

[0016] The output shaft of the grinding wheel motor drives the crank to rotate, the crank drives the connecting rod to move, and the connecting rod pulls the grinding motor to move back and forth, which in turn drives the grinding wheel to move back and forth. This allows the outer surface of the grinding wheel to make more uniform contact with the burrs, thereby avoiding excessive wear on part of the outer surface of the grinding wheel, thus giving the grinding wheel a longer service life, making it suitable for widespread use.

[0017] The right-angle support strip can fit the right-angle edge of the mold well, and burrs can be accommodated inside the burr accommodating groove. The right-angle support strip can be pushed smoothly along the right-angle edge of the mold. This design helps to improve ease of use. Attached Figure Description

A rod shaft 306 is located inside the two cage tubes 3112. Two gaskets 303 are sleeved on the outside of the rod shaft 306 to prevent the connecting rod 304 from moving along the rod shaft 306. 06. Axial movement: One end of the connecting rod 304 is sleeved in the middle of the rod shaft 306. The other end of the connecting rod 304 is provided with a handle 307. The part of the handle 307 protruding from the connecting rod 304 is fixed inside one end of the crank handle 305.

The plate structure of the rocking motor 308 and the plate structure of the flange tube 3011 are connected by a motor screw 309.

[0035] refer to Figures 6-7 The inner contour of the slide tube 301 corresponds to the outer contour of the connecting cage 311 and the grinding motor 312, and the slide tube 301 suppresses the rotation of the grinding motor 312.

[0036] refer to Figure 3 The outer shaft 3012 of the burr removal assembly 3 is located in the through hole on the lower side of the vertical part of the support frame 204, and the middle part of the pull shaft 210 is located inside the tube end hole 3014.

[0037] refer to Figure 1 The grinding wheel 313 of the burr removal component 3 is located inside the support opening 101 in the right-angle support bar 1.

[0038] Working principle: This helmet mold manufacturing surface deburring device presses the right-angle support strip 1 onto the burred edge of the mold. Then, the cranking motor 308 and the grinding motor 312 are started. When the grinding wheel 313 contacts the burr on the edge of the mold, the slide tube 301 will rotate along the axis of the outer shaft 3012 to compress the spring 202. As the burr is removed, the spring 202 will return to its original position. The crank handle 305 and the connecting rod 304 driven by the cranking motor 308 will drive the connecting cage 311 to reciprocate, thereby driving the axial movement of the grinding motor 312. The outer surface of the grinding wheel 313 can make sufficient contact with the burr, thus allowing the outer surface of the grinding wheel 313 to... The wear at each point is the same. If it is necessary to adjust the distance between the grinding wheel 313 and the burr, the locking screw 205 of the frame can be loosened, and the position of the elastic angle holding component 2 on the right angle support 1 can be adjusted to adjust the distance between the outer circle of the grinding wheel 313 and the burr. Pushing the right angle support 1 along the edge of the mold can remove the burrs on the edge of the mold. Compared with the removal of burrs by files and chamfering knives, this deburring method can remove burrs more evenly, and the deburring process causes less damage to the mold. Compared with conventional sanding belt or grinding wheel type burr removal devices, the outer circle of the grinding wheel 313 is subjected to a more even load, which can give the grinding wheel 313 a longer service life.
