specific Embodiment approach 1

[0010] Specific implementation mode one: combine Figure 1-Figure 6 Describe this embodiment, a puller with an assembled beam in this embodiment includes a beam, a jack 3 or a lead screw 6, two pull claws 1 and two second fasteners 5, each pull claw 1 is The tail portion of the pull claw 1 is provided with a circular through hole 1-1 along the thickness direction of the pull claw 1, and the tail end face of each pull claw 1 is provided with a second central threaded through hole 1-2 communicating with the circular through hole 1-1, The tool also includes two first fasteners 4, the crossbeam includes a column 2-1 and two connecting shafts 2-2, and the middle part of the column 2-1 is provided with a first central screw thread along its height direction. The hole 2-3, the jack 3 or the lead screw 6 is threadedly connected with the first central threaded through hole 2-3 of the cylinder 2-1, and two connecting shafts 2 are perforated radially on the side wall of the cylinder 2-1 ...

specific Embodiment approach 2

[0011] Specific implementation mode two: combination figure 1 , figure 2 with Figure 5 To illustrate this embodiment, the end surface of the cylinder 2-1 in this embodiment is provided with two third threaded through holes 2-5 opposite to its axial direction, and the two connecting shafts 2-2 pass through the cylinder 2-1. The two third threaded holes 2-5 are threadedly connected, and the two connecting shafts 2-2 respectively abut against the two first fasteners 4 in the positioning grooves 2-4 to realize detachable connection. With such a setting, the connection is simple, convenient and reliable. Others are the same as in the first embodiment.

Abstract

The invention discloses a puller with an assembly type crossbeam, relates to a puller of detaching parts and aims to solve the problems that an existing puller for detaching wheel type parts is complicated in processing technology, high in cost, low in matching accuracy and limited in application range. The puller comprises the crossbeam, a jack or lead screw, two pulling claws, two second fastening parts and two first fastening parts. The tail of each pulling claw is provided with a circular through hole along the thickness direction. The crossbeam comprises a cylinder and two connecting shafts, the jack or lead screw is in threaded connection with a first center threaded through hole of the cylinder, the two connecting shafts are penetratingly arranged on the side wall of the cylinder along the radial direction, each connecting shaft is detachably connected with the cylinder via one of the first fastening parts, the outer side of each connecting shaft is provided with a positioning groove, and the cylinder is in threaded connection with a second center threaded through holes on the pulling claws. The puller with the assembly type crossbeam is used for detaching small, large or heavy wheel type parts.

Description

technical field [0001] The invention relates to a puller for removing parts, in particular to a puller for removing small, large or heavy wheel parts. Background technique [0002] At present, when disassembling wheel parts, the claws of the puller and the beam are mostly matched with square holes or T-shaped holes or fastened with screws. The matching accuracy is low, and the use is unreliable. Open, can't bear the force, the tools with square holes or T-shaped holes are integrated, after the beam is damaged, the whole set of tools is thrown away, which is a serious waste and inconvenient to use. [0003] Use an adjustable puller to disassemble wheel parts. With the change of the diameter of the pulley, the claw and the pulley are often in point contact, and it is easy to dismantle the pulley. The parts fit with low precision and shake, and the small shaft and screw on the puller are easy to be pulled. Broken, the small shaft is broken, and most people just find a screw to...
