Abstract
The invention discloses a hot-melting jig. The hot-melting jig comprises a fixed seat and a plurality of hot-melting columns connected with the fixed seat, wherein the lower ends of the hot-melting columns are melting heads; a hot-melting sleeve is arranged right below each melting head; the upper end and the lower end of the hot-melting sleeve are opened hollow column bodies; the hot-melting sleeves are positioned at the peripheries of the melting heads, can be sheathed at the peripheries of melting columns of a melting piece, and are provided with movable connecting rods and springs; the springs are fixed on the fixed seat; and the upper ends of the movable connecting rods are connected with the lower ends of the springs, and the lower ends of the movable connecting rods are connected with the hot-melting sleeves. The hot-melting jig disclosed by the invention has the beneficial effects that when the hot-melting jig presses downwards, firstly the hot-melting sleeves press downwards to wrap the peripheries of the melting columns of the melting piece, then the hot-melting columns press downwards to laminate the melting columns, and since the peripheries of the melting columns are firstly wrapped by the hot-melting sleeves before hot melting, the heating deformation and expansion generated by the melting columns when the hot-melting columns press downwards can be set, so that the hot-melting glue can be effectively prevented from overflowing, the shape of a melted product is regular and attractive, and further the production yield and the production efficiency are increased.
Description
Technical field
The present invention designs a kind of hot melting fixture, is specifically related to a kind of hot melting fixture that PUR can be prevented excessive.
Background technology
Hot melt is welded on a body B by a fixture A, fixture and body can be referred to as weldment, wherein, this fixture is generally provided with some through holes, and correspondingly on this body be provided with some welding welding post B1, these welding posts on body are arranged in these through holes on fixture, by hot melting fixture C, the welding post on body is molten into PUR, PUR after fusing can cover through hole and the bore periphery of fixture, when forming cover layer after PUR solidification, now, fixture is held between cover layer and body, thus reach and make fixture be fused to object on body.
But the hot melting fixture structure of prior art is comparatively simple, generally be connected with several hot molten columns C2 on a holder C1, the bottom of welding post is welded joint, by welded joint hot melt and the welding post pressed down on body, during hot melt, PUR easily overflows to periphery, cause the cover layer out-of-shape of final formation, profile unsightly, need often debugging board to improve, therefore affect production efficiency.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of hot melting fixture, hot melting fixture of the present invention can effectively prevent PUR excessive, and after making welding, product design is regular, attractive in appearance, and structure is simple, easy to implement.
The present invention in order to the technical scheme solving its technical problem and adopt is:
A kind of hot melting fixture, comprise holder and be connected to some hot molten columns of holder, the lower end of described hot molten column is welded joint, hot melt sleeve is provided with immediately below each described welded joint, it is peripheral that described hot melt sleeve is positioned at described welded joint, the welding post that described hot melt sleeve can be placed on the body of weldment is peripheral, be provided with movable connecting rod and spring, described spring has longitudinal retractility, described spring is fixed on described holder, described movable connecting rod upper end is connected with lower spring end, described movable connecting rod lower end and described hot melt sleeve connection.
Further technical scheme of the present invention is:
The structure of described movable connecting rod lower end and described hot melt sleeve connection is: be provided with contiguous block, and described contiguous block is in the side-walls of described hot melt sleeve by aggregates for some hot melt sleeve connection, and the lower end of described movable connecting rod is connected with described contiguous block.
Described movable connecting rod outer cover is provided with sleeve pipe, described its lower end block is in described contiguous block, the top of described movable connecting rod is positioned at outside described sleeve pipe, the top of described movable connecting rod is formed with radially outer boss, and the lower surface of described boss can lean with the upper surface of described sleeve pipe.
The structure that described movable connecting rod upper end is connected with lower spring end is: described movable connecting rod upper end is connected with connector, and described connector is connected with lower spring end.
Contiguous block and described hot melt sleeve are integrated.
The invention has the beneficial effects as follows: hot melting fixture of the present invention is provided with hot melt sleeve and for the movable connecting rod that is connected with holder by hot melt sleeve and spring, when hot melting fixture presses down, it is peripheral that hot melt sleeve first presses down the welding post encasing weldment, then hot molten column presses down the pressing of welding post again, because welding post periphery first encases by hot melt sleeve before hot melt, can by the hot molten column temperature distortion that welding post produces when pressing down and sizing of expanding, can effectively prevent PUR excessive, after making welding, product design is regular, attractive in appearance, and then improve production yield and efficiency.

Detailed description of the invention
Embodiment: a kind of hot melting fixture, comprise holder 1 and be connected to some hot molten columns 2 of holder, the lower end of described hot molten column is welded joint 21, hot melt sleeve 3 is provided with immediately below each described welded joint, described hot melt sleeve 3 is hollow cylinders that upper and lower side is all opening, it is peripheral that described hot melt sleeve 3 is positioned at described welded joint 21, the welding post B1 that described hot melt sleeve can be placed on the body B of weldment is peripheral, be provided with movable connecting rod 4 and spring 5, described spring has longitudinal retractility, described spring 5 is fixed on described holder 1, be provided with contiguous block 6, described contiguous block in the side-walls of described hot melt sleeve 3 by aggregates for some hot melt sleeve connection, contiguous block 6 and described hot melt sleeve 3 are integrated.The lower end of described movable connecting rod 4 is connected with described contiguous block 6, described movable connecting rod 4 outer cover is provided with sleeve pipe 7, described its lower end block is in described contiguous block 6, the top of described movable connecting rod 4 is positioned at described sleeve pipe outer 7, the top of described movable connecting rod 4 is formed with radially outer boss 41, the lower surface of described boss 41 can lean with the upper surface of described sleeve pipe 7, and described movable connecting rod 4 upper end is connected with connector 8, and described connector 8 is connected with spring 5 lower end.
When hot melting fixture presses down, it is peripheral that hot melt sleeve 3 first presses down the welding post B1 encasing weldment, then hot molten column 2 presses down welding post B1 pressing again, because welding post B1 periphery first encases by hot melt sleeve 3 before hot melt, can by the hot molten column temperature distortion that welding post produces when pressing down and sizing of expanding, can effectively prevent PUR excessive, after making welding, product design be regular, attractive in appearance, and then improves production yield and efficiency.
