Description

Technical Field

[0001] This utility model relates to the field of gantry robot technology, specifically a gantry robot box frame welding structure. Background Technology

[0002] The gantry robot consists of two vertically and symmetrically arranged pillars, with a horizontally arranged movable frame on top of each pillar. A rack is installed on the top of each pillar, and housings are installed at both ends of the movable frame for mounting geared motors. Gears that mesh with the rack are installed on the drive ends of the geared motors. The gears are driven by the geared motors to rotate, thereby enabling the movable frame to move horizontally.

[0003] The enclosure is constructed by welding steel plates together. The welding process not only introduces positional errors but also causes deformation. Therefore, to improve the enclosure's precision, specialized tooling is required, which leads to high costs and complex welding procedures. Utility Model Content

[0004] To address the technical problems in the background art, this utility model discloses a gantry robot box frame welding structure.

[0005] This utility model provides a gantry robot box frame welding structure, including a box, which is set at both ends of a movable frame. The movable frame is located at the upper end of the column and can move horizontally. The box is made of flat plate welding, and the flat plate at the welding point is respectively set as a first welding plate and a second welding plate.

[0006] The first welding plate is provided with insertion holes, and the second welding plate is provided with welding blocks;

[0007] The welding block is inserted into the socket;

[0008] The welding block and the first welding plate are fixed together by welding;

[0009] The first and second welding plates are fixed together by fillet welding.

[0010] The beneficial effects of the above setup are: 1. By using the welding block to snap into the insertion hole, the first and second welding plates are installed and positioned, eliminating the need for traditional tooling and achieving the same positional accuracy after welding, thereby reducing costs, simplifying operations, and improving assembly efficiency; 2. Welding and fixing the first and second welding plates at two locations results in a higher connection strength.

[0011] The shape of the socket directly affects the positional accuracy of the first and second soldering plates. Based on this, a further improvement is made: the socket is a non-circular hole.

[0012] The amount of welding material used between the welding block and the first welding plate directly affects the connection strength between the welding block and the first welding plate. Based on this, a further improvement is made: the end of the welding block is hidden in the insertion hole, so that the end of the welding block and the first welding plate form a welding cavity, and the welding material fills the welding cavity during welding.

[0013] The depth of the welding block inserted into the socket directly affects the snap-fit ​​stability of the first and second welding plates and the welding strength between the welding block and the first welding plate. Based on this, a further improvement is made: the depth of the welding cavity is set to 2±0.5mm.

[0014] The specific structure of the enclosure is as follows: it includes a front side panel and a back side panel arranged vertically and parallel to each other, and the front side panel and the back side panel are provided with insertion holes; a support plate forming the four-sided frame is vertically connected to the middle of the back side panel, and the support plate is provided with welding blocks that are inserted into the insertion holes of the back side panel; a reinforcing plate is connected between the front side panel and the back side panel, and welding blocks are provided on both sides of the reinforcing plate that are inserted into the insertion holes of the front side panel and the back side panel.

[0015] The beneficial effects of this utility model are: 1. By using the welding block to snap into the insertion hole, the first welding plate and the second welding plate are installed and positioned, eliminating the need for traditional tooling and achieving the same positional accuracy after welding, thereby reducing costs, simplifying operations, and improving assembly efficiency; 2. The first welding plate and the second welding plate are welded and fixed at two locations, resulting in a higher connection strength. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] This utility model discloses a welded frame structure for a gantry robot, including a housing disposed at both ends of a movable frame for mounting reduction motors. The movable frame is located at the upper end of a column. A horizontally arranged rack is provided at the top of the column, and a reduction motor is provided on the housing. A gear meshing with the rack is installed at the drive end of the reduction motor, and the gear rotates by driving the reduction motor to realize the horizontal movement of the movable frame.

[0025] The enclosure includes a vertically arranged, parallel front panel 3 and a back panel 4, both with horizontally extending insertion holes 1. The center of the back panel 4 protrudes upwards and is vertically connected to a support plate 5 forming the four-sided frame. The support plate 5 has protruding welding blocks 2 that insert into the insertion holes 1 of the back panel 4. A reinforcing plate 6 connects the front panel 3 and the back panel 4, with protruding welding blocks 2 on both sides that insert into the insertion holes 1 of the front panel 3 and the back panel 4. The insertion holes 1 are not perfectly circular to improve the positioning accuracy of the engagement between the support plate 5 and the back panel, the reinforcing plate 6 and the front panel 3, and the reinforcing plate 6 and the back panel. In this embodiment, the insertion hole 1 is an oblong hole.

[0026] The corners where the support plate 5 connects to the rear side plate, the corners where the reinforcing plate 6 connects to the front side plate 3, and the corners where the reinforcing plate 6 connects to the rear side plate are all fixed by welding. This weld is a fillet weld. The welding block 2 is also fixed to the front side plate 3 and to the rear side plate by welding. This weld is a planar splice weld.

[0027] Compared with the prior art, the beneficial effects of this embodiment are: 1. By using the welding block 2 to engage with the insertion hole 1, the first welding plate and the second welding plate are installed and positioned, eliminating the need for traditional tooling and achieving the same positional accuracy after welding, thereby reducing costs, simplifying operations, and improving assembly efficiency; 2. The first welding plate and the second welding plate are welded and fixed at two locations, resulting in a higher connection strength.

[0028] The welding block 2 is joined to the front side plate 3 and to the rear side plate using planar splicing welding, resulting in lower connection strength. Therefore, the end of the welding block 2 is hidden within the insertion hole 1, forming a welding cavity between the end of the welding block 2 and the outer surface of the front side plate 3, and between the end of the welding block 2 and the outer surface of the rear side plate. During welding, the welding material fills the welding cavity. The depth of the welding cavity is set to 2±0.5mm to avoid excessive depth, which would affect the connection strength, and to avoid excessive depth, which would affect the stability of the snap-fit.

[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
