Abstract
The utility model relates to a pneumatic tool, that is a crushing and impact pick axe comprising a cylinder block and a pick axe clamping bit. A wear-resistant metal sleeve is arranged between the cylinder block and the pick axe clamping bit, so the pick axe clamping bit is not directly worn by the cylinder block in the process of reciprocating motion, avoiding that the cylinder block is damaged, prolonging the service life of the cylinder block and abolishing the position of the original spring. The utility model is simple in structure and convenient to use.
Description
Technical field
The utility model relates to a kind of pneumatic tools, promptly broken impacting pickaxe.
Background technology
In prior art, impacting pickaxe is applicable to road construction, construction, and soft mineral is smashed in housing demolition, exploits clay, destroys firm or frozen ground etc.Conventional impacting pickaxe comprises cylinder block and directly is set in the interior pick rod of cylinder block leading section, pick rod is spacing by the spring that the cylinder block head connects, and its shortcoming is in use, pick rod in the reciprocating motion and cylinder block mutual friction mutually, damage cylinder body easily, increase cost of use; Also, increased processing cost, and spring also is consumable accessory, increases cost of use equally, influence impacting pickaxe service life because of the setting of spring.
The utility model content
The purpose of this utility model is to provide a kind of processing simple at above-mentioned deficiency, the broken impacting pickaxe that use cost is low.
Technical solution of the present utility model is: broken impacting pickaxe, comprise cylinder block and the pick rod that is set in the cylinder block leading section, and lining has the antifriction metal (AFM) cover between cylinder block and the pick rod.
The utility model has the advantages that: between cylinder block and pick rod, increased the antifriction metal (AFM) cover, made pick rod in reciprocating motion, directly not wear and tear, avoided the cylinder block damage, improved cylinder block service life with cylinder block.Cancelled the setting of original spring, simple in structure, easy to process.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is an impacting pickaxe structure diagram in the prior art;
Fig. 2 is the utility model structure diagram.
The specific embodiment
Referring to Fig. 1, conventional impacting pickaxe comprises cylinder block 1 and directly is set in pick rod 2 in cylinder block 1 leading section, and the spring that pick rod 2 connects by cylinder block 1 head is spacing 3, and wearing and tearing cylinder block 1 and processing are inconvenient during these structure pick rod 2 work.
Referring to Fig. 2, broken impacting pickaxe comprises cylinder block 1 and is set in the pick rod 2 of cylinder block leading section that lining has antifriction metal (AFM) cover 6 between cylinder block 1 and the pick rod 2.Antifriction metal (AFM) cover 6 is consumable accessorys, is convenient for changing.Antifriction metal (AFM) overlaps 6 materials and is plumbous cover or 20Cr alloy cover or the like.
Is connected by wearing bearing pin 4 between antifriction metal (AFM) cover 6 and the pick rod 2, pick rod 2 surfaces that should bearing pin 4 places are processed with one section groove 5 vertically, pick rod 2 is had vertically go here and there and move the space.
Claims (2)
1. broken impacting pickaxe comprises cylinder block (1) and is set in the pick rod (2) of cylinder block (1) leading section, it is characterized in that lining has antifriction metal (AFM) cover (6) between cylinder block (1) and the pick rod (2).
2. according to the described broken impacting pickaxe of claim 1, it is characterized in that being connected by wearing bearing pin (4) between antifriction metal (AFM) cover (6) and the pick rod (2), the pick rod surface of should bearing pin (4) locating is processed with one section groove (5) vertically.
