Abstract
The utility model discloses a marking tool which comprises a cylinder, wherein a bolt head sleeve which is buckled with a to-be-screwed bolt and a tightening boss are arranged on the cylinder; a sleeve cavity is formed in the bolt head sleeve; a through hole communicated with the sleeve cavity is formed in the cylinder; a marking rod is arranged in the through hole and sleeved with a spring; one end of the spring is contacted with a baffle plate arranged in the through hole, and the baffle plate separates the sleeve cavity from the through hole; and a threaded section is formed in the through hole and is in threaded connection with a top plug. The marking tool is matched with a stroke of the threaded section through the top plug, so that the marking time of the marking rod is controlled, a bolt which meets the requirements of the number of tightening turns can be marked, therefore, the condition that the bolt is forgotten to be tightened or the tightening torque is insufficient is avoided, and the production efficiency is improved.
Description
Technical field
The instrument that the utility model uses when relating to a kind of stubborn bolt relates in particular to a kind of device that can carry out mark to the bolt of tightening.
Background technology
At present in the production process, the tightening method of bolt is to use earlier the pneumatic impact spanner pretension bolt, carries out fastening with the automatic screwing device moment of bolting on then.Because the prior pretension mistake of bolt, its position is identical with the position after the make-up torque, is easy to take place automatic screwing device and leaks the accident of twisting bolt in a large amount of assembling processes.Twist for fear of leaking, the bolt that needs after tightening to want manually will tighten with the oil pen is done mark.But the handmarking is wasted time and energy, and still mistakes and omissions takes place easily.
Summary of the invention
The utility model provides a kind of marking tool in order to solve the problem that relates in the background technology.
The technical solution of the utility model is: a kind of marking tool, comprise stack shell, described stack shell is provided with and treats the bolt headgear that stubborn bolt is interlocked and tighten boss, described bolt head is arranged with a mantle cavity, be provided with a through hole that communicates with mantle cavity in the described stack shell, be provided with marking rod in the described through hole, described marking rod is arranged with spring outward, one end of described spring contacts with the baffle plate on being arranged on through hole, described barrier partitions described mantle cavity and through hole, also be provided with thread segment on the described through hole, fill in by the top that has been threaded on the described thread segment.
The mantle cavity that the utility model puts by bolt head is interlocked with bolt to be tightened, link to each other with external motive device and tighten boss, also move downward along thread segment when turning Shi Dingsai thereupon, after pushing up plug and marking rod contact, the promotion marking rod moves downward, marking rod contacts with waiting to tight a bolt, and finishes mark.After the end, stack shell separates with waiting to tight a bolt, and the top plug resets by thread segment, and loosens the compressing to marking rod, and marking rod is return under the effect of spring.
As of the present utility model a kind of preferred, described marking rod is provided with the mark ball near an end of mantle cavity, and described mark ball is provided with a plurality of for pigment feed orifice that pass through and that run through the mark ball.
Because bolt head is harder, the end of marking rod is more fragile usually, and the mark ball is set the service life that has prolonged marking rod, and arranging of feed orifice strengthened the infiltration capacity of mark pigment as paint or ink etc., makes mark more clear.
As of the present utility model a kind of preferred, described marking rod is provided with the body of rod and the following body of rod, and the described diameter of the body of rod of going up is greater than the diameter of the following body of rod, and described spring contacts with the last body of rod away from an end of mantle cavity.
The installation of spring that the setting of the upper and lower body of rod is not only firm, and reduced the overall weight of marking rod, overall structure is more light.
As of the present utility model a kind of preferred, described going up in the body of rod and the following body of rod is filled with water-absorbing material, and described mark ball is embedded in down an end of the body of rod.
Water-absorbing material be arranged so that the easier storage of pigment in the body of rod, and easy to leak not.
As of the present utility model a kind of preferred, described water-absorbing material is sponge.
As of the present utility model a kind of preferred, described mark ball is made by plastics or rubber or metal.
As of the present utility model a kind of preferred, the shape of cross section of described mantle cavity is hexagon.
As of the present utility model a kind of preferred, described stack shell is made by ferroalloy, and through Quenching Treatment.
In sum, the utlity model has following advantage:
The utility model cooperates with the stroke of thread segment by the top plug, has controlled the mark opportunity of marking rod, makes that satisfying the bolt of necessarily tightening the number of turns just can be labeled, and has therefore avoided the leakage of bolt to twist or the not enough situation of screw-down torque, has improved production efficiency.
Description of drawings
Fig. 1 is the schematic diagram of a kind of preferred embodiment of the present utility model.
The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of marking tool, comprise stack shell 1, described stack shell 1 is provided with and treats the bolt headgear 11 that stubborn bolt is interlocked and tighten boss 12, described bolt headgear 11 is provided with a mantle cavity 111, be provided with a through hole 13 that communicates with mantle cavity 111 in the described stack shell 1, be provided with marking rod 2 in the described through hole 13, the described marking rod 2 outer springs 3 that are arranged with, one end of described spring 3 contacts with baffle plate 14 on being arranged on through hole 13, described baffle plate 14 has been separated described mantle cavity 111 and through hole 13, also is provided with thread segment 131 on the described through hole 13, fills in 4 by the top that has been threaded on the described thread segment 131.Described marking rod 2 is provided with mark ball 21 near an end of mantle cavity 111, and described mark ball 21 is provided with a plurality of for pigment feed orifice that pass through and that run through mark ball 21.Described marking rod 2 is provided with the body of rod 22 and the following body of rod 23, and the described diameter of the body of rod 22 of going up is greater than the diameter of the following body of rod 23, and described spring 3 contacts with the last body of rod 22 away from an end of mantle cavity 111.Described going up in the body of rod 22 and the following body of rod 23 is filled with water-absorbing material, and described mark ball 21 is embedded in down an end of the body of rod 23.Described water-absorbing material is sponge.Described mark ball 21 is made by rubber.The shape of cross section of described mantle cavity 111 is hexagon.Described stack shell 1 is made by ferroalloy, and through Quenching Treatment.
