The wrench comprises three through holes which are formed on the side face of the head part of a wrench body and are distributed on the same circumference; a bolt is arranged in each through hole, and is fixed on the wrench body through a nut respectively; the front end part of a screw rod of each bolt is positioned outside the nut; and the front end part of each screw rod is positioned on the same side of the wrench body.
Description
Technical field
The utility model relates to a kind of instrument fastening or dismounting usefulness that is used for, and is specifically related to a kind of spanner.
Background technology
The dismounting and the mounting means of existing a kind of oil cylinder cover are: utilize hammer to knock push rod, tighten, unclamp oil cylinder cover through impulsive force.Oil cylinder cover as shown in Figure 5; These oil cylinder cover 10 tops have four blind holes 11; When tightening or unclamp oil cylinder cover; The insertion blind hole that push rod is tilted also utilizes hammer to knock push rod, tighten or unclamp oil cylinder cover through impulsive force, but this dismounting, impulsive force that mounting means produced is easy to damage sealing ring, influences sealing effectiveness; And easily oil cylinder cover is damaged; Simultaneously, the labour intensity of this dismounting and mounting means is big, wastes time and energy inefficiency.Be that this oil cylinder cover can't be tightened or unclamps oil cylinder cover through existing spanner on the other hand.For example, Chinese patent publication number CN2744470, open day on December 07th, 2005; The name of innovation and creation is called spanner; This application case discloses a kind of spanner, comprises wrench body and driving end, it is characterized in that: described driving end is the flywheel that interior axle has the plum blossom structure that matches with nut.The spanner of this application case can be twisted common nut, but it can not be used for tightening or unclamping this oil cylinder cover equally.
The utility model content
The purpose of the utility model is in order to overcome existing oil cylinder cover in dismounting with when installing, damage oil cylinder cover easily, and labour intensity to be big, ineffective problem, provide a kind of can be safely, the novel spanner of reliable and labour-saving dismounting and installation oil cylinder cover.
The technical scheme of the utility model is:
A kind of novel spanner; Said wrench body head side is provided with three through holes that are distributed on the same circumference; Being provided with bolt in each through hole also is fixed on the wrench body through nut respectively; The screw front end portion of said each bolt is positioned at outside the nut, and each screw front end portion is positioned at the same side of wrench body.The through hole that is provided with on the wrench body head side in this programme is that each blind hole with respect to the oil cylinder cover upper surface is provided with.Three interior bolts that are provided with of through hole are equivalent on wrench body head one side, be provided with three pins.When needs are tightened or unclamp oil cylinder cover, can pass through this spanner, the blind hole of the insertion oil cylinder cover upper surface that the screw rod of the bolt that Wrench head is provided with is corresponding is fixed on Wrench head on the oil cylinder cover; Then rotating spanner shank is tightened oil cylinder cover or unclamp.Dismantle and install oil cylinder cover safety, reliable through this spanner, can not damage the sealing ring and the oil cylinder cover body of oil cylinder cover; Simultaneously, also can reduce labour intensity, increase work efficiency.On the other hand, this spanner structure is simple, reasonable in design, and it does not need die sinking to make; Also need not pass through welding procedure, three pins of welding on wrench body head side are used to cooperate the blind hole of inserting the oil cylinder cover upper surface when tightening or unclamp oil cylinder cover.The wrench body of this spanner can be directly steel plate through 6 millimeter be cut into, will be bolted to the wrench body head then and get final product, can reduce cost of manufacture, improve make efficiency.Simultaneously, as the bolt that pin uses, when tightening or unclamp oil cylinder cover, be a main stressed member, damage easily; If this pin fixedly installs, be to be difficult to maintenance in damage; And the bolt of this programme spanner only needs simply bolt to be changed to get final product if damage.
As preferably, bolt comprises head and screw rod, and said screw rod is step-like, and screw front end portion is the cylinder of diameter less than spiro rod rear end portion, and spiro rod rear end portion has screw thread.The screw front end portion of this bolt is a cylinder, can be used as pin and inserts the corresponding blind hole in oil cylinder cover upper surface, helps dismounting and oil cylinder cover is installed.
As preferably, the wrench body head is provided with magnet.Because this oil cylinder cover is the irony part; So produce suction between meeting and the magnet; When the user with the blind hole of the screw rod of Wrench head and oil cylinder cover upper surface over against the time, the screw rod of Wrench head can insert the blind hole of oil cylinder cover upper surface with screw rod automatically under the suction of magnet.Like this be arranged on the installation and removal oil cylinder cover time, convenient, can increase work efficiency.
As preferably, the shank of spanner is a hollow structure, and is arranged with exsertile second shank in it.When oil cylinder cover is difficult to unclamp, can second sheathed in the spanner shank shank be pulled out, the length of the lengthening spanner arm of force is convenient to dismantle oil cylinder cover.
As preferably, through hole is an arc-shaped through-hole.Because the relative position of corresponding each through hole that is provided with of the relative position of each blind hole and Wrench head on the oil cylinder cover; When processing and fabricating; Possibly produce deviation; So each through hole of Wrench head is set to arc-shaped through-hole, if screw rod when the blind hole that can't insert on the oil cylinder cover, can be finely tuned the relative position of each screw rod through arc-shaped through-hole.
As preferably, the wrench body head also has the opening that can twist bolt or nut.Behind the Bolt dismantling of this spanner on, can also use as common spanner with it.
As preferably, the shank of spanner is provided with the plastic sheath that is used to shake hands.The plastic sheath that the spanner shank is provided with can play a protective role to user's hand.
As preferably, the material of wrench body is: Q235, the material of said bolt is: 40Gr.Bolt when tightening or unclamp oil cylinder cover, is a main stressed member, need bear bigger power, and 40Gr is a kind of structural alloy steel, and top load promptly impacted during the bolt that has it to process can bear.
The beneficial effect of the utility model is: can be safely, reliable and labour-saving dismounting and oil cylinder cover is installed.
