Description

Technical Field

[0001] This utility model relates to the field of welding positioning and clamping technology for steel pipe furniture, specifically a welding positioning and clamping device for steel pipe furniture. Background Technology

[0002] The welding positioning and clamping technology for steel tube furniture is a key process in metal furniture manufacturing. Its core value lies in ensuring the spatial positional relationship of welded components through precise mechanical fixing methods.

[0003] Existing technologies have the following shortcomings: In the current steel pipe furniture manufacturing field, welding positioning and clamping processes generally rely on fixed mechanical structures to achieve precise workpiece positioning. These traditional clamping devices, with their rigid support characteristics and preset positioning benchmarks, can ensure the geometric accuracy and welding strength of steel pipe joints during mass production. However, this standardized design has significant application limitations: when faced with non-standard customization or small-batch, scattered orders, the rigid structure of fixed clamps makes it difficult to adjust the clamping angle and spatial position in real time, resulting in an inability to adapt to diverse steel pipe orientations and irregular joint requirements. The inherent characteristics of this mechanical structure make it insufficient in terms of flexibility, which not only restricts the rapid changeover capability of the production line but also increases the difficulty of achieving special specifications in the manufacturing process. Utility Model Content

[0004] To address the lack of flexibility in positioning and clamping in existing technologies, this utility model provides a positioning and clamping device for welding steel pipe furniture, which solves the current problem of inconvenience in positioning and clamping scattered steel pipe structures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe furniture welding positioning and clamping device, comprising a covering shell and an arm guard ring for protecting the arm, characterized in that: two positioning clamps are provided on the side end of the covering shell.

[0006] A rack is provided on the side end of the positioning clamp.

[0007] A motor for driving is installed inside the side end of the encased shell.

[0008] A drive gear is provided at the motor output end to move the rack and pinion.

[0009] As a preferred embodiment of this utility model, the rack is detachably mounted to the side of the positioning clamp by bolts, and the drive gear meshes with the rack between the two racks.

[0010] As a preferred technical solution of this utility model, a limiting slider for fixing the rack stroke is provided on the side end of the rack, and a pad for preventing the rack from accidentally falling off due to exceeding the stroke is provided on the side end of the limiting slider.

[0011] As a preferred technical solution of this utility model, the cross-sections of the limiting slider and the pad are both cross-shaped, wherein the limiting slider is embedded in the side end of the covering shell and establishes a sliding connection relationship.

[0012] As a preferred technical solution of this utility model, a reinforcing strap is provided on both sides of the rear end of the encasing shell, and a handle for hand gripping is provided inside the encasing shell.

[0013] As a preferred embodiment of this utility model, an air pump is embedded inside the side end of the casing, and a high-pressure air port for cleaning the welding surface is inserted into the other side of the casing.

[0014] As a preferred embodiment of this utility model, the air pump is connected to a high-pressure air port via a pipe, and the top of the casing is hollowed out to serve as an air inlet.

[0015] Compared with the prior art, this utility model provides a welding positioning and clamping device for steel pipe furniture, which has the following beneficial effects:

[0016] A steel pipe furniture welding positioning and clamping device is disclosed. The device is secured by an arm-worn casing. Initial fixation is achieved by inserting the palm into the casing and gripping the handle, followed by reinforcement via straps around the forearm. During welding, the operator aligns one hand with the predetermined welding surface of the steel pipe. An air pump blows high-pressure air from the high-pressure port, removing dust and impurities from the welding surface. The motor then starts, synchronously driving the racks on both sides and the positioning clamps via drive gears until the positioning clamps grip the steel pipe from both sides. The operator's other hand can then access the welding torch for welding. When positioning and clamping scattered steel pipe furniture, the range of the high-pressure airflow or the clamping angle of the positioning clamps can be quickly adjusted by rotating the arm.

[0017] Through the aforementioned setup and process, this structure, compared to traditional fixed-position clamping devices, adopts an ergonomic wearable design, integrating the clamping mechanism directly into the operator's forearm. This lightweight configuration allows the worker to hold the steel pipe with only one hand, achieving real-time positioning and clamping of the workpiece through natural arm movements, making it particularly suitable for the localized processing of non-standard steel pipe components. Its core advantage lies in its dynamic adaptability in three-dimensional space: the clamping unit intelligently follows the operator's wrist rotation, flexion, and extension movements, automatically adjusting the clamping angle and force direction to precisely match the spatial orientation of the steel pipe. This biomimetic operating mode not only frees up the other hand for auxiliary operations but also enables rapid positioning of steel pipes at multiple angles through muscle memory, significantly improving the efficiency and process freedom of pre-processing irregularly shaped pipe components.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 In this embodiment: a steel pipe furniture welding positioning clamping device includes a covering shell 1 and a protective arm ring 2 for protecting the arm. Two positioning clamps 7 are provided on the side of the covering shell 1. When the positioning clamps 7 move in opposite directions, they can squeeze the steel pipe placed in the middle closer together for welding processing.

[0026] The positioning clamp 7 can be a rectangular structure or any shape that can move the steel pipe.

[0027] In order to enable the positioning clamps 7 to move synchronously in opposite directions, a rack 6 is provided on the side of the positioning clamps 7, and a motor 4 for driving is provided inside the side of the housing 1. A drive gear 5 for driving the rack 6 is provided at the output end of the motor 4. This way, after the motor 4 drives the drive gear 5 to rotate, it can synchronously drive the racks 6 on both sides to move in opposite directions, thereby achieving the purpose of moving the positioning clamps 7 in opposite directions.

[0028] The rack 6 is detachably mounted to the side of the positioning clamp 7 by bolts, and the drive gear 5 meshes with the rack 6 between the two racks 6.

[0029] To ensure the stability of the rack 6 during movement, a limiting slider 8 is provided on the side of the rack 6 to fix the travel of the rack 6, and a pad 9 is provided on the side of the limiting slider 8 to prevent the rack 6 from accidentally falling off due to exceeding its travel.

[0030] Both the limiting slider 8 and the pad 9 have cross-shaped cross sections, with the limiting slider 8 embedded in the side of the covering shell 1 and establishing a sliding connection.

[0031] To enable the welding and positioning of steel pipe furniture to be performed with one hand, a reinforcing strap 3 is installed on both sides of the rear end of the cover shell 1, and a handle 12 for the palm to grip is installed inside the cover shell 1. This allows the cover shell 1 to be worn on the operator's forearm and establish a firm connection, thereby achieving the purpose of one-handed operation.

[0032] In order to achieve better welding results for steel pipe furniture, an air pump 10 is embedded inside one side of the casing 1, and a high-pressure air port 11 is inserted and set on the other side of the casing 1. This allows the steel pipe structure to be blown off the external attachments by the high-pressure airflow before welding, thereby improving the welding effect.

[0033] The air pump 10 is connected to the high-pressure air port 11 through a pipe, and the top of the casing 1 is hollowed out as the air inlet.

[0034] In this embodiment, the protective shell 1 is secured by wearing an arm strap. Initial fixation is achieved by inserting the palm into the protective shell 1 and gripping the handle 12, followed by a reinforced connection via a strap 3 around the forearm. During steel pipe furniture welding, the operator aligns one hand with the predetermined welding surface of the steel pipe. The air pump 10 blows off dust and impurities from the welding surface using high-pressure airflow from the high-pressure air port 11. Then, the motor 4 starts, synchronously driving the racks 6 on both sides and the positioning clamps 7 via the drive gear 5, until the positioning clamps 7 clamp the steel pipe from both sides. The operator's other hand can then pick up the welding torch for welding. When positioning and clamping scattered steel pipe furniture, the range of airflow from the high-pressure air port 11 or the clamping angle of the positioning clamps 7 can be quickly adjusted by rotating the arm.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
