Abstract
The utility model relates to a clamp for correcting the size of an automobile rear cover part. The clamp comprises a clamp body which is a rectangular plate. A plurality of clamping elements and two supporting elements are arranged on the clamp body. The clamping elements are arranged around the clamp body and form an annular shape which is the same as the shape of the part, and the supporting elements are arranged in the middle of the clamp body and located inside the annular space defined by the clamping elements. Compared with the prior art, in order to solve the problem that edge flatness of the automobile rear cover part is prone to influence, the part is positioned in an assistant mode in the non-work area of the station, a clamping head is added to the clamp, the clamping head compresses the part by adopting large-area nylon blocks in a face contact mode, it is ensured that the part does not deform, the size of the part which slightly deforms in the process can be corrected, hidden dangers are completely eradicated, and therefore it is ensured that qualified and satisfying products are provided for customers.
Description
Technical field
The utility model relates to a kind of fixture, especially relates to a kind of fixture of correcting accessory size for automobile rear case.
Background technology
Bodywork parts is more and more higher to the requirement of size at present, and weld jig belongs to the servicing unit in welding process, and in automobile high volume production process, this device is absolutely necessary.The part large and soft when encountering, rigidity is poor, or run into while needing the quality problems of solution more special, just must increase auxiliary positioning point, or adjust the position of anchor point, mainly solution is two matching problems, i.e. vehicle body flatness and gap.Flatness be rear cover assembly with vehicle body Z, X to mate, gap is that rear cover assembly Y-direction is mated with vehicle body.
Conventional last one station of hinge being installed being usually positioned at welding assembly, part basic forming, and clamp quantity is few or only RPS point is positioned.In the installation process of hinge, because installation site is to be positioned at part edge substantially, the turning moment that hinge rifle produces easily causes the twist distortion of part, directly has influence on the coupling of part flatness.
Utility model content
The purpose of this utility model be exactly a kind of rational in infrastructure, reliable in quality is provided in order to overcome the defect that above-mentioned prior art exists correct the fixture of accessory size for automobile rear case.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of fixture of correcting accessory size for automobile rear case, comprise chuck body, this chuck body is rectangular slab, described chuck body is provided with clamping element and support component, and described clamping element is provided with several, around the surrounding that is around in chuck body, form an annular identical with parts profile, described support component is provided with two, is located at respectively the centre of chuck body, and is positioned at clamping element and surrounds annular inside.
Described clamping element is divided into alignment pin clamping element and profile clamping element, and described alignment pin clamping element is for part is accurately located, and described profile clamping element is for part surrounding is fixedly clamped, and guarantee bonnet mates with vehicle body.
Described clamping element is provided with 20 altogether, described alignment pin clamping element is provided with two, is located at respectively on the both sides that chuck body is just right, and described profile clamping element is provided with 18, around the surrounding that is around in chuck body, form an annular identical with parts profile.
Described support component is the bracing frame for support part.
In described chuck body, be also provided with the setting element for coarse positioning, described setting element is the alignment pin playing the role of positioning.
In described chuck body, be also provided with the guide for supplement production and guide effect.
The top of described clamping element is nylon block chuck, and the top of described support component is nylon block cushion block.
Described chuck body is the foundation that each element is installed, containing cylinder mounting bracket and alignment pin mounting bracket.
The profile module of mating with digital-to-analogue is installed on the mounting bracket of fixture according to part digital-to-analogue, to profile position and size profile accurately process, can meet design requirement as much as possible thereby finely tune in the clamping profile to accurate processing the part that ensures to clamp after orthopedic.
Compared with prior art, the utlity model has following advantage and beneficial effect:
(1) for the easy influenced problem of automobile rear case part edge flatness, in this station inoperative region to part auxiliary positioning, on fixture, increase chuck, chuck adopts the form compressing component of large-area nylon block with face contact, not only can guarantee that part is indeformable, and the accessory size of a small amount of distortion in energy correcting process, provide against hidden trouble from root, thereby guarantee to be delivered to client's product of qualified satisfaction on hand.
(2) existing conventional fixture does not have orthopedic function, only the RPS position of part is positioned, thereby only can ensure part X, Z-direction size, when being installed, hinge use receives in the situation of other external force compared with high pulling torque or part, be easy to cause part quality problem, be gently dimensional discrepancy, heavy part is scrapped, and also can increase technical staff's workload simultaneously.And fixture of the present utility model uses the fixture with orthopaedic function, at the finishing operation of whole production line, accessory size is proofreaied and correct, be satisfied product on hand thereby can ensure to deliver to client.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1 is chuck body, 2 is support component, and 3 is alignment pin clamping element, and 4 is profile clamping element.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
A kind of fixture of correcting accessory size for automobile rear case, as shown in Figure 1, comprise chuck body 1, this chuck body 1 is rectangular slab, chuck body 1 is provided with clamping element and support component 2, and clamping element is divided into alignment pin clamping element 3 and profile clamping element 4, and alignment pin clamping element 3 is for accurately locating part, profile clamping element 4 is for part surrounding is fixedly clamped, and guarantee bonnet mates with vehicle body.Clamping element is provided with 20 altogether, and alignment pin clamping element 3 is provided with two, is located at respectively on the both sides that chuck body 1 is just right, and profile clamping element 4 is provided with 18, around the surrounding that is around in chuck body 1, forms an annular identical with parts profile.Support component 2 is provided with two, is located at respectively the centre of chuck body 1, and is positioned at clamping element and surrounds annular inside.Support component 2 is the bracing frame for support part.In chuck body 1, be also provided with the setting element for coarse positioning, setting element is the alignment pin playing the role of positioning.In chuck body 1, be also provided with the guide for supplement production and guide effect.The top of clamping element is nylon block chuck, and the top of support component 2 is nylon block cushion block.Chuck body 1 is the foundation that each element is installed, containing cylinder mounting bracket and alignment pin mounting bracket.
