According to the technical scheme provided by the utility model, the detachable pin pulling component suitable for the manual pin pulling device comprises a pin pulling screw, a nut sleeve, a connecting stud and a pull rod of the manual pin pulling device; two ends of the connecting stud are respectively provided with a section of external thread and are respectively connected with the nut sleeve and the pull rod of the manual pin puller; the two ends of the nut sleeve are respectively provided with a slotted hole, an internal thread is arranged in the slotted hole at one end and is connected with the external thread of the connecting stud, and the slotted hole at the other end is used for embedding the pin pulling screw; the pull rod of the manual pin puller is provided with a slidable collision block.
As a further improvement, the nut sleeve is connected with the pin pulling screw through a slotted hole, the opening diameter of the nut sleeve is larger than the diameter of the pin pulling screw, and the diameter of the screw head of the pin pulling screw is smaller than the diameter of the pin pulling screw.
As a further improvement of the utility model, the opening side of the nut sleeve is provided with a flat head which is characterized by comprising a pair of parallel planes.
As a further improvement of the utility model, the middle position of the connecting stud is provided with a flat body which is characterized by comprising a pair of parallel planes.
As a further improvement of the utility model, the axes of the pin pulling screw, the nut sleeve, the connecting stud and the pull rod of the manual pin pulling device are on a straight line.
The utility model discloses simple structure, design benefit uses in a flexible way, utilizes ordinary screw to act as the pulling pin screw, and can change this screw alone, can improve work efficiency, practices thrift cost of maintenance.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic structural view of the nut case of the present invention.
Description of reference numerals: the pin pulling device comprises a pin pulling screw 1, a nut sleeve 2, a flat head 2-1, a connecting stud 3, a flat body 3-1, a manual pin pulling device pull rod 4 and a collision block 5.
Detailed Description
The present invention will be further described with reference to the drawings.
As shown in fig. 1 and 2, a detachable pin pulling assembly suitable for a manual pin puller comprises a pin pulling screw 1, a nut sleeve 2, a connecting stud 3 and a pull rod 4 of the manual pin puller; two ends of the connecting stud 3 are respectively provided with a section of external thread and are respectively connected with the nut sleeve 2 and the pull rod 4 of the manual pin puller; the two ends of the nut sleeve 2 are respectively provided with a slotted hole, an internal thread is arranged in the slotted hole at one end and is connected with the external thread of the connecting stud 3, and the slotted hole at the other end is used for embedding the pin pulling screw 1; the pull rod 4 of the manual pin puller is provided with a slidable collision block 5.
Furthermore, the opening diameter of the slotted hole for connecting the nut sleeve and the pin pulling screw 1 is larger than the screw diameter of the pin pulling screw 1 and smaller than the screw head diameter of the pin pulling screw 1.
Furthermore, the open side of the nut sleeve 2 is provided with a flat head 2-1 which is characterized by comprising a pair of parallel planes.
Furthermore, a flat body 3-1 is arranged in the middle of the connecting stud 3 and is characterized by comprising a pair of parallel planes.
Further, the axes of the pin pulling screw 1, the nut sleeve 2, the connecting stud 3 and the pull rod 4 of the manual pin puller are on the same straight line.
The utility model discloses the working process is as follows: when the device is used, a proper pin pulling screw 1 and a proper nut sleeve 2 are selected, the pin pulling screw 1 is placed into the nut sleeve 2, the head of the screw is clamped at an opening at the head of the nut sleeve 2, the tail of the nut sleeve 2 is screwed into the connecting stud 3, two wrenches are respectively clamped on the flat head 2-1 of the nut sleeve and the flat body 3-1 of the connecting stud, and the two wrenches are screwed with force; after the components are assembled, the other end of the connecting stud 3 is screwed into the pull rod 4 of the manual pin puller; after the assembly is finished, the pin pulling screw 1 is screwed into the positioning pin, the collision block 5 slides backwards to generate backward pulling force, and the pin pulling screw 1 is driven to pull out the positioning pin; when the pin pulling screw 1 is damaged, the nut sleeve 2 can be unscrewed from the connecting stud 3, and the pin pulling screw 1 can be replaced independently.
