Abstract

The utility model discloses a doorframe welding clamp, which comprises a horizontal table-board and L-shaped locating plates arranged thereon, wherein the four L-shaped locating plates are oppositely arranged to form a rectangular structure with the size and the shape identical to those of an inner frame of the doorframe; compressing devices are in one-to-one correspondence to two mutually-perpendicular plate bodies of each L-shaped locating plate; each compressing device comprises a compression shaft driving assembly and a compression shaft doing the reciprocating movement in the vertical direction of the corresponding plate bodies of the L-shaped locating plates; and the power output ends of the compression shaft driving assemblies are hinged with the compression shafts. When the doorframe welding clamp is used, all parts of the doorframe are positioned through the L-shaped locating plates and are compressed conveniently by the compression shaft driving assemblies; the compressing device is operated simpler and faster relative to thread compression, thereby effectively improving the production efficiency; and besides, the clamp adopts adjustable locating plates, thereby adapting to the welding of doorframes with different specifications and effectively reducing the production cost.

Description

The doorframe weld jig

Technical field

The utility model relates to a kind of doorframe weld jig.

Background technology

In technical process, anchor clamps are used for installing rapidly, easily and safely workpiece, weld jig is to be used for fixing processing object in the process, make it to be in the device of correct position, to guarantee that under hot conditions weldment reaches required size, shape etc., its quality directly has influence on the height of the size and dimension precision of weldment.

At steel door, in the doorframe welding production process of products such as antitheft door, because the length and width size of employed steel plate is much larger than steel plate thickness, very easily distortion in welding process, need to use weld jig rational in infrastructure to guarantee weld size and form accuracy, mainly there are following two problems in existing doorframe weld jig: be the anchor clamps that rely on screw thread to stretch owing to what workpiece was compressed employing 1., it uses convenient inadequately, compress and to unclamp required time longer, be unfavorable for enhancing productivity, simultaneously, advance because compression axis is rotation, also stay cut easily when compressing on workpiece, it is attractive in appearance to influence product; 2. it is non-adjustable to be used to the clamp body size of locating, and the corresponding sleeve clamp of a kind of doorframe of specification is unfavorable for reducing production costs.

At above-mentioned deficiency, need to improve to existing doorframe weld jig, it is compressed and the operation of unclamping more simple and convenient, enhance productivity, simultaneously, its doorframe that can satisfy plurality of specifications welding is used, reduce production costs.

The utility model content

In view of this, the utility model provides a kind of doorframe weld jig, and these anchor clamps can be operated easily and carry out compress and release action, simultaneously, can adapt to the doorframe welding of plurality of specifications, helps enhancing productivity and reducing production costs.

Doorframe weld jig of the present utility model, comprise level table and the L shaped location-plate that is arranged on the level table, described four L shaped location-plates are oppositely arranged and form and the identical rectangular configuration of doorframe inside casing size and dimension, described level table is provided with and two orthogonal plate bodys of each L shaped location-plate hold down gag one to one, described hold down gag comprises compression axis driven unit and the compression axis that can move back and forth along the vertical direction of the corresponding plate body of L shaped location-plate, described compression axis driven unit comprises base, drive link and the driving handle hinged with base, the two ends of described drive link are hinged with driving handle and compression axis respectively, and described driving handle forms the retaining face in the hinged place bending.

Further, the vertical direction of the corresponding plate body of the L shaped location-plate in described base upper edge is provided with guide cylinder, and compression axis and guide cylinder are slidingly matched;

Further, described L shaped location-plate and hold down gag all are installed on the level table removably.

The beneficial effect of utility model: doorframe weld jig of the present utility model, comprise level table and the L shaped location-plate that is arranged on the level table, described four L shaped location-plates are oppositely arranged and form and the identical rectangular configuration of doorframe inside casing size and dimension, the corresponding one by one hold down gag that is provided with of two orthogonal plate bodys with each L shaped location-plate, described hold down gag comprises compression axis driven unit and can be along the compression axis of the up-and-down motion of the corresponding plate body of L shaped location-plate, the hinged compression axis of the clutch end of compression axis driven unit, during use, the parts of respectively forming of doorframe are located by L shaped location-plate, can compress it easily by the compression axis driven unit, utilize the screw thread hold down gag that stretches to operate more simple and fast with respect to routine, can effectively enhance productivity, in addition, anchor clamps adopt adjustable location-plate, can adapt to the welding of different size doorframe, effectively reduce production costs.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of hold down gag.

The specific embodiment

Fig. 1 is a structural representation of the present utility model, Fig. 2 is the structural representation of hold down gag, as shown in the figure: the doorframe weld jig of present embodiment, comprise level table 1 and the L shaped location-plate 2 that is arranged on the level table 1, described four L shaped location-plates 2 are oppositely arranged and form and the identical rectangular configuration of doorframe inside casing size and dimension, described level table 1 is provided with and two orthogonal plate bodys of each L shaped location-plate 2 hold down gag 3 one to one, described hold down gag 3 comprises compression axis driven unit and compression axis 4, described compression axis driven unit comprises base 5, drive link 6 and the driving handle 7 hinged with base 5, the two ends of described drive link 6 are hinged with driving handle 7 and compression axis 4 respectively, the vertical direction of the L shaped location-plate 2 corresponding plate bodys in described base 5 upper edges is provided with guide cylinder 9, compression axis 4 is slidingly matched with guide cylinder 9, form the structure that compression axis 4 can reciprocatingly slide along guide cylinder 9, described driving handle 7 forms retaining face 8 in the hinged place bending, during use, the parts of respectively forming of doorframe are located by L shaped location-plate, can compress it easily by the compression axis driven unit, after compression axis puts in place, the elastic force that is positioned the steel plate self on the L shaped location-plate applies axially outside thrust to compression axis, make the retaining face withstand base, prevent that hold down gag unclamps automatically after unclamping driving handle, compress reliable, utilize the screw thread hold down gag that stretches to operate more simple and fast with respect to routine, can effectively enhance productivity.

In the present embodiment, described L shaped location-plate 2 and hold down gag 3 all are installed on the level table 1 removably, anchor clamps adopt dismountable location-plate and hold down gag, can pull down at any time and reorientate, form the rectangle location structure of different size, adapt to the welding of different size doorframe, effectively reduce production costs.
