Description
Technical field
The present invention relates to a kind of radiator centre and dry equipment needed thereby when welding, particularly relate to a kind of auxiliary fixture adopted when a kind of radiator centre dries weldering.
Background technology
The auxiliary fixture drying weldering for radiator centre assembles and be used in baking weldering process auxiliary clamping radiator centre, make it to be ensured by fixture relative to the positional precision of fuse kludge, thus ensure that the radiator centre drying postwelding is not by the impact of workman's technical merit, makes the machining accuracy of product reach unanimity.This auxiliary fixture being used for radiator centre is mainly used in assembling in radiator centre manufacture process, dries welder's sequence.For the design of the auxiliary fixture of radiator centre for the purpose of ensureing that involved procedure requires, ensure emphatically assembling product size and dry weldering quality; Package size mainly refers to the spacing dimension of radiator centre two backplate, and all the other such as main leaf spacing dimensions are then ensured by kludge; Dry weldering quality and mainly refer to that auxiliary fixture dries the impact of weldering quality to product except baking soldering equipment relative parameters setting, it mainly ensures with product quality and appearance and size.
In prior art, because solder flux can not effectively flow out, cause the accumulation of solder flux, cause and dry the normal and backplate of postwelding auxiliary fixture and bond, and produce bad scrapping.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide a kind of auxiliary fixture drying weldering for radiator, for solving the technical problem that in prior art, solder flux can not effectively flow out, prevent the bonding of auxiliary fixture and backplate, also prevent the accumulation of heat-radiation belt solder flux and produce bad.
For achieving the above object and other relevant objects, the invention provides a kind of auxiliary fixture drying weldering for radiator centre, draw together the first accessory plate, second accessory plate and five joint pins, joint pin is made up of body and two links, the height of body is 12mm, the diameter of body is that 8mm first accessory plate and the second accessory plate are provided with five connecting holes, two links of joint pin are placed in the connecting hole of the first accessory plate and the second accessory plate respectively, joint pin is by the first accessory plate and the parallel connection of the second accessory plate, the dual-side of the first accessory plate and the second accessory plate is dentalation and the structure of the backplate of this dentalation and radiator centre matches, the thickness of the first accessory plate and the second accessory plate is 1.5mm.This is used for radiator centre and dries the auxiliary fixture of weldering for drying the side being sandwiched in radiator centre in weldering process, dries the backplate that the auxiliary fixture welded is stuck in the side of radiator centre during use by whole for radiator centre.During use, on the side abutment backplate of the first accessory plate and the second accessory plate, because the thickness of the first accessory plate and the second accessory plate is 1.5mm, the height of the body of joint pin is 12mm and the diameter of body is 8mm, therefore between the first accessory plate and the second accessory plate, there is enough large space to allow solder flux effectively flow out, prevent the bonding of auxiliary fixture and backplate, also prevent the accumulation of heat-radiation belt solder flux and produce bad.
Further, described first accessory plate and the second accessory plate include left plate, right panel, plate core, maintenance bolt and spring, the right-hand member of left plate is hollow structure, the inwall of left plate is provided with chute and chute two ends are provided with fixed hole, plate core is fixedly connected with the left end of right panel, the matching form of the shape of plate core and the hollow structure of left plate, at the free end of plate core, the position corresponding with chute is provided with telescopic hole, maintenance bolt to be fixedly connected with the bottom of telescopic hole by spring and maintenance bolt by telescopic spring in telescopic hole.For the radiator centre of different model, the auxiliary fixture for radiator centre baking weldering of different length is needed to be clamped by the side of radiator centre.When the length of radiator centre is less, the plate core of the first accessory plate and the second accessory plate is all placed in the hollow structure of left plate, and the fixed hole that maintenance bolt stretches into hollow structure bottom is fixed, and preventing board core rocks in hollow structure; When the length of radiator centre is larger, pull right panel, maintenance bolt on the drive lower plate core of right panel skids off in chute in fixed hole, when maintenance bolt reaches the fixed hole near hollow structure outlet, maintenance bolt stretches in this fixed hole, and the inwall of left plate blocks the movement of maintenance bolt, thus makes plate core not continue to stretch out again, the length of the first accessory plate and the second accessory plate becomes large, thus can match with the radiator centre of greater depth.
Further, described auxiliary fixture 0Cr18Ni9 material making of drying weldering for radiator centre.Select this material to make, make the auxiliary fixture drying weldering for radiator centre have good corrosion resistance, heat resistance, low temperature intensity and mechanical performance, the hot-workabilities such as bending ram are good, without heat treatment hardening phenomenon, nonmagnetic.
Further, the described superficial layer drying the auxiliary fixture of weldering for radiator centre is sprayed molybdenum layer.Superficial layer is sprayed molybdenum layer, and hardness can reach 850-1050HV0.1, and coefficient of friction is low, and tensile property is good, and anti-scuff wear ability is good.
As mentioned above, a kind of auxiliary fixture drying weldering for radiator centre of the present invention, there is following beneficial effect: solve by arranging of the first accessory plate, the second accessory plate and joint pin the technical problem that in prior art, solder flux can not effectively flow out, prevent the bonding of auxiliary fixture and backplate, also prevent the accumulation of heat-radiation belt solder flux and produce bad.
