Abstract
The utility model discloses an auxiliary disassembly and assembly device for a fuel injector. The fuel injector is disassembled and assembled through a vise. The auxiliary disassembly and assembly device comprises two parallel cushion blocks and an elastic connecting piece, wherein flat clamping positions of the fuel injector are covered by the cushion blocks, the outer side faces of the cushion blocks are connected with the inner side faces of clamping walls of the vise in an abutting mode, and the two ends of the elastic connecting piece are fixed to the ends of the two cushion blocks respectively. According to the auxiliary disassembly and assembly device for the fuel injector, the height of each cushion block is no larger than that of the corresponding clamping flat position so that surface contact is formed between the inner side faces of the cushion blocks and the fuel injector as well as between the outer side faces of the cushion blocks and jaws of the vise, the large friction moment is generated, the fuel injector can be kept still by the vise through small clamping force, and abrasion and deformation of the fuel injector caused by sliding turning of the fuel injector can be avoided.
Description
Technical field
The utility model relates to mechanical field, particularly a kind of auxiliary disassembling device of fuel injector.
Background technology
While keeping in repair fuel injector in prior art, need dismounting fuel injector, conventionally fuel injector is clamped on brave bench vice, utilize the jaw of brave bench vice and the fricative moment of fuel injector to make fuel injector keep motionless.As shown in Figure 1, the height of the flat position 11 of the clamping of fuel injector 1 is far smaller than the thickness of the jaw of brave bench vice, and what therefore brave bench vice 2 clamped is the flat position of the periphery of fuel injector 1 rather than the clamping of fuel injector.Because having formed line with fuel injector 1, the jaw 21 of brave bench vice 2 contacts, the moment of friction that tiger bench vice produces is less, during dismounting, fuel injector easily trackslips, and can to the chucking power of fuel injector, strengthen moment of friction by increasing brave bench vice, but can cause so accurate even distortion of fuel injector wearing and tearing.
The information that is disclosed in this background technology part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply that in any form this information structure has been the known prior art of persons skilled in the art.
Utility model content
The purpose of this utility model is to provide a kind of auxiliary disassembling device of fuel injector, thereby the assembly and disassembly methods that overcomes the fuel injector of prior art causes the even defect of distortion of fuel injector wearing and tearing.
For achieving the above object, the utility model provides a kind of auxiliary disassembling device of fuel injector, fuel injector carries out dismounting by brave bench vice, auxiliary disassembling device comprises: two cushion blocks that be arranged in parallel, cushion block is for covering the flat position of clamping of fuel injector, and the medial surface butt of the lateral surface of cushion block and the double wall of brave bench vice; And Flexible Connector, the two ends of Flexible Connector are separately fixed at the end of two cushion blocks.
Preferably, in technique scheme, Flexible Connector is elastic steel sheet.
Preferably, in technique scheme, the height of cushion block is not more than the height of the flat position of clamping of fuel injector.
Preferably, in technique scheme, the length of cushion block is not less than the width of the flat position of clamping of fuel injector.
Compared with prior art, the utlity model has following beneficial effect:
The height of cushion block of the present utility model is not more than the height of the flat position of clamping, all formation face contacts between the medial surface that makes cushion block and fuel injector and between the lateral surface of cushion block and the jaw of brave bench vice, produced larger moment of friction, tiger bench vice can utilize less chucking power to make fuel injector keep motionless, wearing and tearing and the distortion of the fuel injector that can avoid fuel injector to trackslip causing; In addition, the length of cushion block is not less than the width of the flat position of clamping, and the friction area between cushion block and jaw increases, and for clamping provides larger friction, and such flexible design is applicable to the fuel injector of the flat position of clamping of different size, applied widely; Flexible Connector can prevent auxiliary disassembling device landing, facilitates like this one man operation.

Main description of reference numerals:
1-fuel injector, the flat position of 11-clamping, 2-tiger bench vice, 21-jaw, 3-auxiliary disassembling device, 31-cushion block, 32-Flexible Connector.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of the specific embodiment.
Unless separately there is other clearly to represent, otherwise in whole description and claims, term " comprises " or its conversion was stated being understood to include as " comprising " or " including " etc. element or part, and do not get rid of other element or other part.
As shown in Figure 2, on fuel injector 1, be arranged with two flat positions 11 of clamping.
As shown in Figure 3-4, according to the auxiliary disassembling device 3 of the fuel injector of the utility model specific embodiment comprise two cushion blocks that be arranged in parallel 31 with for being connected the Flexible Connector 32 of two cushion blocks 31.The two ends of Flexible Connector 32 are separately fixed on the side of two cushion blocks 31, and Flexible Connector 32 makes to have certain clamping force between two cushion blocks 31, are not easy landing when clamping fuel injector.
Preferably, the height of cushion block 31 is not more than the height of the flat position 11 of clamping.Preferably, the length of cushion block 3 is not less than the width of the flat position 11 of clamping.Preferably, Flexible Connector 32 is elastic steel sheet.
As shown in Figure 3, two cushion blocks 31 of auxiliary disassembling device 3 cover respectively on the flat position 11 of two clampings of fuel injector 1, and then auxiliary disassembling device 3 is clamped between two jaws 21 of brave bench vice 2 together with fuel injector 1, the lateral surface butt of jaw 21 and cushion block 31.
The height of cushion block of the present utility model is not more than the height of the flat position of clamping, all formation face contacts between the medial surface that makes cushion block and fuel injector and between the lateral surface of cushion block and the jaw of brave bench vice, produced larger moment of friction, tiger bench vice can utilize less chucking power to make fuel injector keep motionless, wearing and tearing and the distortion of the fuel injector that can avoid fuel injector to trackslip causing; In addition, the length of cushion block is not less than the width of the flat position of clamping, and the friction area between cushion block and jaw increases, and for clamping provides larger friction, and such flexible design is applicable to the fuel injector of the flat position of clamping of different size, applied widely; Flexible Connector can prevent auxiliary disassembling device 3 landings, facilitates like this one man operation.
