Automatic production device for precise machining of rotating pin holes of ratchet wrench heads

Abstract

The invention discloses an automatic production device for precise machining of rotating pin holes of ratchet wrench heads. The automatic production device comprises a vibration feeding disc and a drilling machine device; a spiral surrounding type feeding plate is arranged in the vibration feeding disc; a layer-limited guide plate, a material discharging groove and a material sorting groove are sequentially arranged on the spiral surrounding type feeding plate in the moving direction of parts; a matching baffle is arranged opposite to the layer-limited guide plate, and the spiral surrounding type feeding plate is connected to a discharging rail; the discharging rail is connected to a guide bin; a pushing device is arranged at the lower end of the guide bin and comprises an upper-layer feeding sliding groove and a lower-layer feeding sliding groove which are stacked mutually; a first pushing plate is arranged on the upper-layer feeding sliding groove; a second pushing plate is arranged on the lower-layer feeding sliding groove; the tail end of the first pushing plate and the tail end of the second pushing plate are connected to a telescopic device; and the drilling machine device is positioned right above the pushing device. According to the automatic production device, orientation sorting can be carried out rapidly on the ratchet wrench heads in batches, drilling and reaming machining can be carried out on the ratchet wrench heads, the production efficiency is high, machining is stable and reliable, the precision is high, the potential safety hazard is avoided, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of hardware tool manufacturing, and in particular relates to an automatic production equipment for finishing the repin hole of a ratchet wrench head. Background technique [0002] Ratchet wrench head structure as Figure 7 As shown, the overall shape is arc shape, one end is thin, one end is wide, and the wide end is provided with a pin hole 903; the inner cutting edge 901 is a polygonal structure, and the outer arc surface 902 is arc. Due to the small size of the ratchet wrench head parts, it is very difficult to process the repin hole 903. The traditional method generally adopts ordinary clamps to clamp the ratchet wrench head tightly, and then drills holes through ordinary lathes, milling machines or manually. Sometimes workers are required to hold the ratchet wrench head one by one on the lathe and then take it to the milling machine for milling, or take it to manual drilling. Every ratchet wrench head to be proce...
