Description
Technical field
The utility model relates to a kind of motorcycle durability experimental rig, especially a kind of motorbike frame journal stirrup welding clamping and positioning device.
Background technology
In frame of motorcycle welding tooling, in welding during with the parts of internal thread and smaller size smaller or journal stirrup, can adopt special fixture to carry out clamping and positioning from screwed hole, existing clamping device structure adopts monoblock type or knockdown screw thread alignment pin to position clamping mostly.
All-in-one-piece clamping and positioning device, structure generally comprises supporting base, lining and only has threaded location, one end to clamp polished rod; Wherein the front end of location clamping polished rod is limited in journal stirrup on supporting base by threaded engagement, and polished rod part and the lining of rear end coordinate to guarantee its levelness.So in use, clamp the threaded one end of polished rod and use through long-term, the factors such as the electric shock when welding of screw thread experience and wearing and tearing under normal circumstances and inevitably artificial damage, cause screw thread position to use and the frequent clamping polished rod of changing.Mutually wear and tear because of lining endoporus and the polished rod position that clamps polished rod, it is large that lining endoporus becomes simultaneously, and the polished rod position diameter that clamps polished rod reduces.Causing clamping polished rod to rock in bush hole changes the journal stirrup position dimension of its welding.In changing clamping polished rod, need more resleeve.Clamping polished rod and lining under changing cannot reuse, and have directly increased manufacturing cost.
Knockdown clamping and positioning device, structure generally comprises supporting base and clamping screw rod, have clamping screw front end a preceding thread section forward thread segment level run through and are engaged on supporting base, on described clamping screw rod, also there is rear thread section, described rear thread section is provided with the threaded adjusting lining for keeping clamping screw stem water Pingdu and adjusting clamping screw axial displacement, and described threaded adjusting lining side arranges clamping screw.The clamping and positioning device of this mode, can remove the clamping screw rod of front end wearing and tearing rear continuation of damage section and use, and has saved cost.But stressed larger owing to installing entirety when it uses, the distance of threaded engagement is longer, usually cause between rear thread section and threaded adjusting lining, during because of mismachining tolerance or work, wearing and tearing easily produce loosening, cause the clamping screw rod of having located in the time exiting Combined locating pin after having welded in welding work pieces, not exit smoothly, exist and use very inconvenient defect.
Therefore be necessary to design a kind of advantage that can either possess above-mentioned two kinds of modes, there is the defect that can overcome above-mentioned two kinds of modes, can be convenient for changing to save cost, use simultaneously and change the very convenient welding of Motorcylce support lug efficiently clamping and positioning device.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide a kind of simple in structure, can save use cost, use the very convenient journal stirrup of the motorbike frame efficiently welding in location clamping and positioning device simultaneously.
In order to solve the problems of the technologies described above, in the utility model, adopt following technical scheme:
A kind of motorbike frame journal stirrup welding clamping and positioning device, comprise supporting base, be horizontally set on the lining of supporting base upper end, and be horizontally disposed with and front end have the double-screw bolt section for locating location clamp polished rod, it is characterized in that, described location clamps polished rod and is made up of the positioning threads pin removably connecting and polished rod body, positioning threads pin front end is the described double-screw bolt section for locating, positioning threads pin rear end has connecting stud section and spins and is engaged in the installation screw at polished rod body front end face axle center place, polished rod body front end has one section of rotation being rotatably engaged in lining and coordinates section.
Motorbike frame journal stirrup welding clamping and positioning device of the present utility model, location clamps polished rod and is made up of the positioning threads pin removably connecting and polished rod body two parts, when use, rotation polished rod body drives the location of positioning threads pin front end to be screwed onto in journal stirrup screw by double-screw bolt section, realizes the location of journal stirrup.When location rotation, by polished rod body and the rotation that coordinates of lining coordinate section to ensure its levelness, fast and accurate for positioning reliable while guaranteeing to use.When using a period of time, location can be dismantled separately and still fall positioning threads pin after being scrapped with the wearing and tearing of double-screw bolt section, polished rod body can continue to use, so only need to change separately the positioning threads pin of small volume, need not still fall whole location and clamp polished rod, avoided wasting and providing cost savings.
As optimization, in described rotation cooperation section, radially offer a screw hole being communicated with installation screw, in described screw hole, be provided with a fluting headless screw, fluting headless screw front end is inserted in the locating notch of a coupling in the connecting stud section of the positioning threads pin in installation screw, and fluting headless screw rear end flushes the rotation of polished rod body and coordinates section surface position.
Like this, between positioning threads pin and polished rod body, realize detachable connection by a fluting headless screw, it is simple in structure, can ensure the transmission of moment of torsion, connects and is reliably convenient to dismounting and does not affect the cooperation that the rotation of polished rod body coordinates section and lining.
As optimization, on described polished rod body, rotation coordinates a section rear end to have a diameter and become large limited step, and limited step and lining rear end end face coordinate spacing.
Like this, make this device with time can lean on limited step and lining rear end end face to coordinate spacingly to judge that whether front end positioning threads pin is inserted in the screw of journal stirrup completely, judges whether to realize location.The use of convenient device.
As optimization, described positioning threads pin middle part has one section of outer surface and sleeve inner surface coupling and the rotatable enlarged diameter section coordinating.
Like this, when this device longer service time, between the rotation cooperation section of polished rod body and lining, produce after wearing and tearing, can also lean on the enlarged diameter section of positioning threads pin self and the cooperation of sleeve inner surface to ensure the levelness of positioning threads pin, guarantee that clamping all the time fast accurately and reliably.
Further, the cutting of the both sides of the enlarged diameter section of described positioning threads pin is formed with two symmetrically arranged clamping planes.
Like this, need to change positioning threads pin time, can dismantle two rear realizations of clamping plane clamping by spanner, be convenient for changing dismounting.
As optimization, polished rod body rear end is vertically installed with a rotation application of force handle.
Like this, the application of force can rotation easy to use time.
In sum, the utility model has overcome the deficiencies of two kinds chucking lugs of prior art and has taken into account advantage separately simultaneously, has simple in structurely, can save use cost, uses the very convenient advantage efficiently in location simultaneously.
