Abstract

The utility model discloses a large chamfer piston rod assembly tool, which comprises a first arc-shaped plate and a second arc-shaped plate, wherein two connecting ends of the first arc-shaped plate are both provided with a clamping groove, two connecting ends of the second arc-shaped plate are both fixedly connected with a clamping block matched with the clamping groove, and inner rings of the first arc-shaped plate and the second arc-shaped plate are both fixedly connected with a buffer layer; simple structure is simultaneously, and is very convenient when installing it, inserts the preparation stage of piston rod at the counterpoint, need not accurate counterpoint, directly with the piston rod insert two buffer layer formed in the round hole can, because the setting of cambered surface, the phenomenon that the card pause can not take place for the very smooth process of inserting, the method efficiency of comparing traditional manual cut straightly is more heightened, can not produce the inner wall of cylinder body simultaneously and scrape the damage.

Description

Large-chamfer piston rod assembling tool

Technical Field

The utility model belongs to auto-parts processing field particularly, relates to a big chamfer piston rod erecting tool.

Background

The piston rod is a connecting component for supporting the piston to do work, most of the piston rod is applied to an oil cylinder and an air cylinder movement executing component, and the piston rod is a movement component with frequent movement and high technical requirements. Taking a hydraulic oil cylinder as an example, the hydraulic oil cylinder comprises: the cylinder barrel, the piston rod (oil cylinder rod), the piston and the end cover. The quality of the processing quality directly influences the service life and the reliability of the whole product. The piston rod has high processing requirement, the surface roughness requirement of the piston rod is Ra0.4-0.8 mu m, and the requirements on coaxiality and wear resistance are strict. The oil cylinder rod is basically characterized in that a slender shaft is machined, and the machining difficulty is high, so that the oil cylinder rod always troubles machining personnel.

When inserting the inside of cylinder body with the piston rod, need counterpoint the body of rod with the jar mouth, because to the precision requirement when inserting than higher, need consume the certain time when staff's manual counterpoint inserts, even after successfully counterpointing, also can take place the slope at the body of rod in the insertion process, though can not influence the insertion process, nevertheless to the cylinder body, the inclined inserted body of rod produces the inner wall of cylinder body easily and scrapes the damage.

SUMMERY OF THE UTILITY MODEL

To above defect, the utility model provides a big chamfer piston rod erecting tool, including first arc and second arc, the draw-in groove has all been seted up to two links of first arc, the fixture block of the equal fixedly connected with of two links and draw-in groove looks adaptation of second arc, the equal fixedly connected with buffer layer of inner circle of first arc and second arc.

Furthermore, the clamping groove and the clamping block are both T-shaped.

Furthermore, the inner ring of the buffer layer is arc-shaped, and the diameter value of the bottommost end of the annular inner wall formed by the two buffer layers is the same as that of the piston rod.

Further, arc magnet pieces, two are inlaid at the tops of the first arc-shaped plate and the second arc-shaped plate, and opposite magnetic poles which attract each other are respectively arranged at the two ends, close to each other, of the magnet pieces.

Compared with the prior art, the utility model following beneficial effect has:

a big chamfer piston rod erecting tool, simple structure, it is very convenient when installing it, at the preparation stage of counterpointing the insertion piston rod, need not accurate counterpoint, directly with the piston rod insert in the round hole that two buffer layers formed can, because the setting of cambered surface, the phenomenon that the card went up can not take place for the very smooth process of inserting, the method efficiency of comparing traditional manual cut straightly more increases, can not produce the inner wall of cylinder body simultaneously and scrape the damage.

Drawings

Fig. 1 is a plan view of the present invention in a combined state.

Fig. 2 is an exploded view of the present invention during installation.

Fig. 3 is a sectional view of the present invention in the assembled state.

In the figure: 1 first arc, 2 second arc, 3 draw-in grooves, 4 fixture blocks, 5 buffer layers, 6 magnet pieces.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Embodiments of the device are given in the figures. However, the apparatus may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Examples

As shown in fig. 1-3, this embodiment provides a big chamfer piston rod erecting tool, including first arc 1 and second arc 2, arc magnet piece 6 has all been inlayed at the top of first arc 1 and second arc 2, two magnet piece 6 both ends that are close to each other are the opposite magnetic pole of inter attraction respectively, not only play good absorption fixed effect at the assembly part that forms after splicing first arc 1 and second arc 2, when taking out the assembly part in the cylinder body simultaneously, because laminating each other is difficult to directly take out, can use the magnet suction. Draw-in groove 3 has all been seted up to two links of first arc 1, and draw-in groove 3 and fixture block 4 are the T font, increase the connection effect of first arc 1 and second arc 2. Two equal fixedly connected with of link of second arc 2 and the fixture block 4 of draw-in groove 3 looks adaptation, the equal fixedly connected with buffer layer 5 of inner circle of first arc 1 and second arc 2. The inner circle of buffer layer 5 is arc, and the diameter value that annular inner wall bottommost was constituteed to two buffer layers 5 is the same with the diameter value of piston rod, when counterpointing the piston rod, need not the accuracy and counterpoint, directly put into the inside circular slot of assembly part can, and when inserting, because arc buffer layer 5's bottom is perpendicular gradually, consequently also can not hinder the sense when inserting, conveniently inserts the inside of cylinder body.

It should be noted that the structure of the present invention can be realized in many different forms, and is not limited to the embodiments, and any equivalent transformation, or direct or indirect application in other related technical fields, such as loading and unloading of other articles, which is performed by a person skilled in the art using the contents of the present invention and the accompanying drawings, is included in the protection scope of the present invention.
