Description

Combined multipurpose mute pin puller

Technical Field

The utility model discloses the product relates to mechanical technical field, relates to a modular multi-purpose silence pin puller.

Background

In mechanical equipment overhauls, the pin puller that uses at present is mostly striking formula pin puller, is fixed with striking piece on it, and the tip can with the member of the screw threaded connection on the pin pulling shaft terminal surface. During the use, it is fixed with screw threaded connection on member tip and the shop bolt terminal surface, outwards strike the striking piece, utilize the outside impact of striking piece to extract the shop bolt, the required impact of this dismantlement mode is great, used power is artifical direct power of giving, and need have certain striking space, through striking many times, just can extract the shop bolt, often can meet the time and energy waste that dismantlement pin process exists, it is difficult to dismantle, have great impact force, the space is not enough scheduling problem, and can produce the noise at the in-process of hitting, the production job site has noise pollution. Vibration can be generated in the striking process, and the precision of a machine, particularly an ultra-precise part, is influenced; the striking vibration easily causes the surface of the machine part to contact other objects to generate bruise and scratch, and the surface quality of the equipment is influenced; the risk that the striking vibration causes the screw to break and remain in the pin hole influences the pulling-out of the pin.

And the above-mentioned dismantlement mode can only be to the top band hole formula pin, and the mode that uses for the screw cap or mushroom head type pin to dismantling the top is that screw driver or crow bar sled are unable to dismantle, because there is not specialized tool to lead to the operation difficulty, and because the specification of pin is many in addition, and the pulling head of current pin puller only is applicable to the pin of a specification usually, this just makes different pins need adopt the pin puller of corresponding specification to dismantle. Therefore, the existing pin puller is poor in universality.

Therefore, the technical personnel in the field are dedicated to develop a combined type multipurpose mute pin puller, and the combined type multipurpose mute pin puller aims to solve the problem of defects existing in the using process of the existing pin puller.

SUMMERY OF THE UTILITY MODEL

In order to achieve the purpose, the utility model provides a combined type multipurpose mute pin puller, which comprises a T-shaped drawing shaft, a pulling claw, a locking bolt and a fixed sleeve; the vertical shaft of the T-shaped drawing shaft comprises threads and a matched nut; the pulling claw is 2 opposite L-shaped, the vertical edge comprises 2 through holes, the locking bolt transversely penetrates through the through hole at the lower part of the pulling claw, and nuts are matched at two ends of the outer side of the pulling claw; a transverse shaft of the T-shaped drawing shaft transversely penetrates through a through hole in the upper part of the drawing claw; one end of the fixed sleeve is open, the other end of the fixed sleeve is closed, the center of the closed end comprises a central hole, a vertical shaft of the T-shaped drawing shaft penetrates out of the central hole of the closed end of the fixed sleeve, and a nut is matched with the vertical shaft;

in a preferred embodiment of the present invention, the length of the cross shaft of the T-shaped drawing shaft is smaller than the inner diameter of the fixing sleeve;

scheme more than adopting, the utility model discloses a multi-purpose silence pin puller of combination formula has following technological effect:

1. the combined type multipurpose mute pin puller of the utility model has the advantages that the fixed sleeve is sleeved outside the puller, the pin is pulled out by using the rotation of the nut in the pulling process, the striking is not needed to be performed vigorously, the noise is low, the scratch or the bruise to the equipment is avoided, and the maintenance quality is ensured; the labor intensity is greatly reduced, and the working efficiency is improved;

2. the combined multipurpose mute pin puller of the utility model is convenient to use in the equipment maintenance work, can adapt to pins of various forms and models by adjusting the distance between the two claws, has good universality, good popularization value and wide application in the mechanical equipment field and the building installation field;

in summary, the combined multipurpose mute pin puller of the utility model has the advantages of no need of strong striking, no noise, no vibration, stable work, avoiding scratching or damaging equipment and ensuring the maintenance quality; the labor intensity is greatly reduced, and the working efficiency is improved; the universality is good.

The conception, specific structure and technical effects of the present invention will be further described with reference to the accompanying drawings and specific embodiments, so as to fully understand the objects, features and effects of the present invention.

Detailed Description

The embodiments of the present invention will be described with reference to the accompanying drawings for clarity and understanding. The present invention may be embodied in many different forms of embodiments, and the scope of the invention is not limited to the embodiments described herein.

In the drawings, structurally identical elements are represented by like reference numerals, and structurally or functionally similar elements are represented by like reference numerals throughout the several views. The size and thickness of each component shown in the drawings are arbitrarily illustrated, and the present invention is not limited to the size and thickness of each component. The thickness of the components may be exaggerated where appropriate in the figures to improve clarity.

As shown in fig. 1 to 6, the combined multipurpose mute pin puller of the present invention comprises a T-shaped pulling shaft 1, a pulling claw 2, a locking bolt 3 and a fixing sleeve 4; the vertical shaft of the T-shaped drawing shaft 1 comprises a thread 5 and a matched nut 6; the pulling claw 2 is 2 opposite L-shaped, the vertical edge comprises 2 through holes 7, the locking bolt transversely 3 penetrates through the through hole 7 at the lower part of the pulling claw 2, and nuts 6 are matched at two ends of the outer side of the pulling claw 2; the transverse shaft of the T-shaped drawing shaft 1 transversely penetrates through the through hole 7 at the upper part of the pulling claw 2; one end of the fixed sleeve 4 is open, the other end is closed, the center of the closed end comprises a central hole 8, a vertical shaft of the T-shaped drawing shaft 1 penetrates out of the central hole 8 of the closed end of the fixed sleeve 4, and a nut 6 is matched with the vertical shaft;

the combined installation and use process comprises the steps of firstly combining the pulling claws and the locking bolts together as shown in figure 3, then installing the T-shaped pulling shaft in the upper through holes of the pulling claws, adjusting the distance between the two pulling claws in figure 3 to enable the pulling claws to clamp the nuts or mushroom heads at the tops of the pins, then locking the locking bolts, penetrating the central holes of the figure 4 (fixing sleeve) through the T-shaped pulling shaft and sleeving the T-shaped pulling shaft outside the two pulling claws, then screwing the nuts on the vertical shafts, and finally realizing the pulling effect by screwing the nuts.
