Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding equipment for door handle corner hardware. Background Technology

[0002] In the processing of steel products, it is sometimes necessary to weld two parts at right angles. Existing automated welding equipment can perform the welding work automatically, but the fixtures on automated welding equipment can usually only accommodate long or large hardware parts. Although small hardware parts such as door handle corner hardware parts can also be automatically welded, due to their small size, positioning and clamping them is extremely time-consuming, and conventional welding devices can only weld a single position, resulting in weak weld strength. Therefore, there is a need for a welding device for door handle corners that can improve both processing strength and processing efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a door handle corner hardware welding equipment, which aims to solve the problem of weak welding strength of existing corner welding equipment.

[0004] To achieve the above objectives, this utility model provides a door handle corner hardware welding device, including a frame, on which a clamping assembly and a positioning assembly are provided. The clamping assembly includes a base, a rotary table, a rotary motor, a slide table, a sliding drive component, a limit seat, and a lifting clamping component. The base is mounted on the frame and has a rotating shaft seat connected to the rotary table. The rotary motor drives the rotary table to rotate through the rotating shaft seat. The slide table is slidably connected to the rotary table, and the sliding drive component drives the slide table to slide on the rotary table. The sliding direction of the slide table is parallel to the rotation axis of the rotary table. Limit seats are provided on both the slide table and the rotary table, and a lifting clamping component is installed at each set of limit seats. The positioning assembly is located between the slide table and the rotary table for positioning the corner hardware.

[0005] Furthermore, the positioning assembly includes a transverse drive, a transverse slider, and a positioning plate. The transverse drive is mounted on the frame, the transverse slider is slidably mounted on the transverse drive, and a positioning plate is detachably mounted on the transverse slider. The positioning plate is located between the rotary table and the slide table.

[0006] Furthermore, the lifting clamping component includes a lifting cylinder, a connecting plate, and a pressure block; a set of lifting cylinders is installed on both the slide table and the rotary table, and the lifting cylinders are fixedly connected to the pressure block through the connecting plate, with the pressure block located directly above the limit seat.

[0007] Furthermore, the sliding drive component includes a connecting slide rail, a connecting slider, and a sliding cylinder. The connecting slide rail is fixedly connected to the slide table, the connecting slider is fixedly connected to the rotary table, the connecting slide rail and the connecting slider are slidably connected, and the sliding cylinder is mounted on the rotary table.

[0030] The present invention will be described in detail below with reference to specific embodiments.

[0031] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0032] like Figures 2 to 10 As shown, this utility model provides a door handle corner hardware welding equipment, including a frame 1. The frame 1 is equipped with a clamping assembly 2 and a positioning assembly 5. The clamping assembly 2 includes a base 20, a rotary table 23, a rotary motor 21, a slide table 24, a sliding drive component 27, a limit seat 25, and a lifting clamping component 26. The base 20 is mounted on the frame 1 and is equipped with a rotating shaft seat 22. The rotating shaft seat 22 is connected to the rotary table 23. The rotary motor 21 drives the rotary table 23 to rotate through the rotating shaft seat 22. The slide table 24 is slidably connected to the rotary table 23. The sliding drive component 27 is used to drive the slide table 24 to slide on the rotary table 23. The sliding direction of the slide table 24 is parallel to the rotation axis of the rotary table 23. Limit seats 25 are provided on both the slide table 24 and the rotary table 23. A lifting clamping component 26 is installed at each set of limit seats 25. The positioning assembly 5 is disposed between the slide table 24 and the rotary table 23 for positioning the corner hardware.

[0033] It should be noted that the corner hardware is made by welding two sections of straight pipe together (e.g. Figure 1 As shown), the ends of the two straight pipes are provided with beveled corners. Before welding, the two beveled corners are joined together, and after welding, corner hardware can be obtained.

[0034] With the above design scheme, when welding is required at the corner, the slide table 24 first moves away from the rotary table 23. After the slide table 24 is pushed away from the rotary table 23, the operator only needs to place the two straight tubes constituting the corner hardware onto the limiting seat 25 with the assistance of the positioning component 5 (at this time, the positioning effect of the positioning component 5 on the two straight tubes is that when the slide table 24 is close to the rotary table 23, the two beveled corners are exactly aligned). Then, the lifting clamp 26 automatically lowers to lock the two straight tubes onto the limiting seat 25. Then, the positioning component 5 retracts, and the sliding drive component 27 controls the slide table 24 to be close to the rotary table 23, so that the two straight tubes to be welded are attached together. During welding, the rotary motor 21 can also make the rotary table 23 rotate at the corresponding angle, aligning the direction to be welded with the welding part 43 described below, ensuring that different directions of the corner hardware can be welded.

[0035] In this embodiment, the positioning component 5 includes a transverse drive 50, a transverse slider 51, and a positioning plate 52. The transverse drive 50 is mounted on the frame 1, the transverse slider 51 is slidably mounted on the transverse drive 50, and the positioning plate 52 is detachably mounted on the transverse slider 51. The positioning plate 52 is located between the rotary table 23 and the slide table 24.

[0036] With the above design scheme, when two straight pipes of corner hardware to be welded need to be placed, the positioning plate 52 is pushed forward by the transverse drive 50 and the transverse slider 51 until the plate 52 comes between the open slide table 24 and the rotary table 23. The worker pushes the two straight pipes toward the plate 52 until the two beveled corners of the two straight pipes are close to the two sides of the plate 52. At this time, the two beveled corners are separated by a distance by the plate 52, but the two beveled corners are exactly aligned, which makes it convenient for the worker to position the two straight pipes to be welded. After confirming that the two straight pipes are in place, the lifting clamping member 26 clamps them. Then the positioning plate 52 moves back, allowing the slide table 24 to move closer to the rotary table 23, and the two beveled corners are spliced ​​together to facilitate the welding operation.

[0037] In this embodiment, a cylinder is provided inside the transverse drive member 50, and the cylinder is used to push the transverse slider 51 to slide on the transverse drive member 50.

[0038] In this embodiment, the lifting clamping member 26 includes a lifting cylinder 260, a connecting plate 261, and a pressure block 262; a set of lifting cylinders 260 are installed on both the slide table 24 and the rotary table 23. The lifting cylinders 260 are fixedly connected to the pressure block 262 through the connecting plate 261, and the pressure block 262 is located directly above the limiting seat 25.

[0039] In this embodiment, the sliding drive component 27 includes a connecting slide rail 272, a connecting slider 271, and a sliding cylinder 270. The connecting slide rail 272 is fixedly connected to the slide table 24, the connecting slider 271 is fixedly connected to the rotary table 23, the connecting slide rail 272 and the connecting slider 271 are slidably connected, and the sliding cylinder 270 is mounted on the rotary table 23. The sliding cylinder 270 is used to drive the connecting slide rail 272 to slide on the connecting slider 271.

[0040] In this embodiment, a receiving frame 3 is provided on the frame 1, and the receiving frame 3 is located below the limiting seat 25.

[0041] With the above design scheme, after the welding operation is completed, the lifting clamp 26 releases its grip on the corner hardware. Then, the rotary motor 21 rotates the rotary table 23, making the rotary table 23 tilted. Under the action of gravity, the welded corner hardware automatically slides down and falls into the receiving frame 3 below for easy collection. During this process, there is no need for the staff to pick up the corner hardware by hand, avoiding burns to the staff caused by the hot corner hardware after welding.

[0042] In this embodiment, both the rotary table 23 and the slide table 24 have chamfered bottoms.

[0043] The above design scheme facilitates bottom welding operations and avoids the thickness of the rotary table 23 and slide table 24 affecting the welding work at the bottom of the corner hardware.

[0044] In this embodiment, a welding assembly 4 is provided on the frame 1. The welding assembly 4 includes a power unit and a welding unit 43. The power unit is used to drive the welding unit 43 to perform welding operations.

[0045] In this embodiment, the power unit includes a transverse power guide rail 40, a lifting power guide rail 41, and a longitudinal power guide rail 42. The transverse power guide rail 40 is mounted on the frame 1. The transverse power guide rail 40 is used to drive the lifting power guide rail 41 to move laterally. The lifting power guide rail 41 is used to drive the longitudinal power guide rail 42 to move up and down. The longitudinal power guide rail 42 is used to drive the welding part 43 to move longitudinally.

[0046] With the above design, during welding operations, the welding unit 43, driven by the power unit, rises and falls, slides left and right or forward and backward according to a preset program, automatically completing the welding operation. Since the welding unit 43 and the power unit are existing technologies and not key improvements in this embodiment, they are not elaborated upon in this description.

[0047] The door handle corner hardware welding equipment provided by this utility model, compared with the prior art, when door handle corner welding is required, the positioning plate 52 extends and locks between the opened slide table 24 and the rotating seat for positioning. The operator only needs to push inward along the limiting seat 25 to place the two straight tubes of the corner hardware. The lifting clamping member 26 will automatically press down and clamp the two straight tubes of the corner hardware. Then, the positioning plate 52 retracts and the slide table 24 retracts so that the two straight tubes of the corner hardware abut. Then, driven by the power unit and the rotary motor 21, the welding unit 43 automatically performs welding operations on different parts of the corner hardware, so that the corner hardware can be welded in different directions without readjusting the clamping state, thereby improving the welding strength of the corner hardware.

[0048] Where there is no conflict, the above embodiments and features can be combined with each other.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
