Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, specifically to a welding deformation prevention tooling. Background Technology

[0002] Welding fixtures mainly refer to a set of flexible welding fixtures for fixing, clamping, and positioning. They are mainly used for welding various weldable materials, including large, medium, and small materials. This type of welding process equipment is a general term for fixtures, mechanical devices, or equipment that play a coordinating and auxiliary role in the assembly and welding process of welded structures. Most welding fixtures are specially designed for the assembly and welding process of certain welded components and are non-standard devices. The main function of welding fixtures is that, by using welding fixtures, parts are positioned by locators, and accurate assembly positions can be obtained without scribing or measuring, thereby ensuring assembly and processing accuracy and improving work progress.

[0003] Commonly used welding fixtures on the market are mainly composed of a fixture base plate, a fixture body, auxiliary mechanisms, and a control system. Before welding, the workpiece needs to be placed on the fixture base plate and clamped by the fixture body and clamping mechanism to ensure that it does not move or shift during the welding process. The clamping method of this type of fixture can be mechanical, pneumatic, hydraulic, or other forms.

[0004] The welding fixtures mentioned above only hold the material at a certain angle and fix it in place by the clamping structure when clamping the material. The adjustable angle is limited, and the convenience of adjustment is insufficient when facing different welding requirements. At the same time, most fixtures can only clamp a certain type of material, which is a limitation. Therefore, we propose a welding deformation prevention fixture. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] The purpose of this invention is to provide a welding deformation prevention tooling to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a welding deformation prevention fixture, comprising a main body, lifting frames distributed on both sides of the main body, and a clamping mechanism connected to one side of the top of the lifting frames. The clamping mechanism includes a clamping platform, and a connecting post is connected to one end of the clamping platform. A limiting gear post is connected to one end of the connecting post. A toothed sleeve is fitted on the outer wall of the limiting gear post, and a rotating shaft is connected to the axis of the limiting gear post. An adjusting gear post is connected to one end of the rotating shaft, and a clamping frame is connected to one end of the adjusting gear post. A clamping force electric screw is embedded in the center of one side of the clamping frame, and a lower clamping plate is connected to the bottom end of the clamping force electric screw. An upper clamping plate is provided on the top of the lower clamping plate, and a rubber strip is provided at the bottom end of the upper clamping plate. Spring frames are connected to both sides of the top of the rubber strip.

[0008] Furthermore, the adhesive strips form an elastic structure with the upper clamping plate via a spring frame, and the adhesive strips are equidistantly arranged and embedded along the inner walls of the upper and lower clamping plates.

[0009] Furthermore, the clamping frame forms a rotating structure with the limiting gear post through the adjusting gear post and the rotating shaft, and the toothed sleeve meshes with the outer walls of the limiting gear post and the adjusting gear post.

[0010] Furthermore, the main body includes a base, and an annular groove is formed around the top surface of the base. A rotating frame is axially connected to the top surface of the base, and a lifting platform is axially connected to the top surface of the rotating frame. Transverse slide rails are formed at both ends of the rotating frame, and a screw shaft is provided inside the transverse slide rails. A lifting frame is fitted at one end of the screw shaft, and a dual-output shaft motor is connected to one end of the screw shaft.

[0011] Furthermore, the screw shaft is connected and distributed along both ends of the dual-output shaft motor, and the dual-output shaft motor is fixedly connected to the center of the rotating frame.

[0012] Furthermore, the lifting frame includes a boom, and a transverse slider is connected to the bottom end of the boom. A screw shaft is connected to the axis of the transverse slider. A longitudinal slide rail is provided on the inner wall of the boom, and a longitudinal electric screw is connected inside the longitudinal slide rail.

[0013] Furthermore, the boom forms a transmission structure with a transverse slider and a screw shaft, and the longitudinal electric screw is rotatably engaged with the boom.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This fixture holds materials by using a clamping platform and clamping frame connected to the two end arms. By adjusting the gear post and the limit gear post, the clamping frame can be rotated and locked without dead angles. The upper and lower clamping parts of the clamping frame are all made of arranged elastic telescopic rubber blocks. Each set of rubber blocks expands and contracts with elastic pressure, conforming to the surface of the material to adaptively clamp materials of different shapes, maintaining the clamping stability of materials of various shapes and improving the applicability.

[0016] This fixture is connected to the clamping mechanism via a rotating frame mounted on the top surface of the base and lifting frames at both ends. The lifting frames can be connected to the screw shafts at the bottom, and the screw shafts at both ends can be driven to rotate simultaneously by a dual-output shaft motor. This allows the lifting frames on both sides to slide outward or inward simultaneously, thus adapting to clamping materials of different sizes and lengths. The rotating frame itself can rotate, and with the annular groove at the bottom, it can improve the adjustability and stability during the welding process.

[0017] This fixture can be adjusted via booms at both ends. Driven by a longitudinal electric screw in the longitudinal slide rail inside the boom, the connected clamping mechanism can be raised and lowered to meet the height requirements of different welding materials. It can also assist in the alignment and welding of two sets of materials, further improving adjustability. Attached Figure Description

[0029] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] This utility model provides, for example Figure 1The tooling shown includes a main body 1, with lifting frames 2 distributed on both sides of the main body 1, and a clamping mechanism 3 connected to one side of the top of the lifting frame 2. The main body 1 includes a base 101, and annular grooves 102 are formed around the top surface of the base 101. A rotating frame 103 is axially connected to the top surface of the base 101, and a lifting platform 104 is axially connected to the top surface of the rotating frame 103. Transverse slide rails 105 are formed at both ends of the rotating frame 103, and a screw shaft 106 is provided inside the transverse slide rail 105. The lifting frame 2 is sleeved on one end of the screw shaft 106, and a double-output shaft motor 107 is connected to one end of the screw shaft 106.

[0031] To facilitate adjustment when clamping materials of different lengths, such as Figure 1-2 As shown, this fixture is connected to the clamping mechanism 3 via a rotating frame 103 mounted on the top surface of the base 101 and lifting frames 2 at both ends. The lifting frames 2 can be connected to the screw shaft 106 at the bottom, and the screw shaft 106 at both ends can be driven to rotate simultaneously by the dual-output shaft motor 107. This allows the lifting frames 2 on both sides to slide outward or inward simultaneously, thus adapting to clamping materials of different sizes and lengths. The rotating frame 103 itself can rotate, and with the annular groove 102 attached to the bottom, the adjustability and stability during the welding process can be improved.

[0032] like Figure 2 As shown, the lifting frame 2 includes a boom 201, and a horizontal slider 202 is connected to the bottom end of the boom 201. A screw shaft 106 is connected to the axis of the horizontal slider 202. A longitudinal slide rail 203 is provided on the inner wall of the boom 201. A longitudinal electric screw 204 is connected inside the longitudinal slide rail 203.

[0033] To meet the height requirements of different welding processes, such as Figure 2 As shown, this tooling can be adjusted via the booms 201 at both ends. Driven by the longitudinal electric screw 204 in the longitudinal slide rail 203 inside the boom 201, the connected clamping mechanism 3 can be adjusted up and down to meet the height requirements of different welding materials. At the same time, it can assist in the alignment and welding of two sets of materials, further improving adjustability.

[0034] like Figure 3-6As shown, the clamping mechanism 3 includes a clamping platform 301, and one end of the clamping platform 301 is connected to a connecting post 302. One end of the connecting post 302 is connected to a limiting gear post 303. The outer wall of the limiting gear post 303 is fitted with a toothed sleeve 304, and the axis of the limiting gear post 303 is connected to a rotating shaft 305. One end of the rotating shaft 305 is connected to an adjusting gear post 306, and one end of the adjusting gear post 306 is connected to a clamping frame 307. A clamping force electric screw 308 is embedded in the center of one side of the clamping frame 307, and the bottom end of the clamping force electric screw 308 is connected to a lower clamping plate 309. The top of the lower clamping plate 309 is provided with an upper clamping plate 310, and the bottom end of the upper clamping plate 310 is provided with a rubber strip block 311. The top two sides of the rubber strip block 311 are connected to spring frames 312.

[0035] Finally, in order to maintain high adaptability to the materials being clamped, such as Figure 3-6 As shown, this fixture holds the material by clamping platform 301 and clamping frame 307 connected by the two end arms 201. By adjusting the gear post 306 and the limit gear post 303, the clamping frame 307 can be rotated and quickly locked without dead angles. The upper and lower clamping parts of the clamping frame 307 are all connected by elastic telescopic rubber strips 311. Each set of rubber strips 311 adapts to the elastic pressure and expands and contracts, conforming to the surface of the material to adaptively clamp materials of different shapes, maintaining the clamping stability of materials of various shapes and improving the applicability.

[0036] In summary, when using this welding fixture, the material to be clamped can first be placed on the lifting platform 104. Then, the screw shafts 106 at both ends of the rotating frame 103 are driven to rotate by the dual-output shaft motor 107, causing the connected arms 201 to adjust and move closer to the center until the clamping frame 307 mounted on the arm 201 contacts the material. Subsequently, the clamping force electric screw 308 inside the clamping frame 307 rotates and drives the connected lower clamping plate 309 to clamp towards the upper clamping plate 310. During the clamping process, the rubber strips 311 of the two sets of clamping plates contact the material. Due to the influence of the clamping force, each set of rubber strips 311 is elastically compressed. The clamping mechanism is designed to fit as closely as possible to the surface of the material, such as materials with curved surfaces or uneven structures. The clamping frame 307 is then driven upwards to the welding height by the longitudinal electric screw 204 of the boom 201. At this point, the user can rotate the clamping frame 307 as needed. As the clamping frame 307 rotates, the connecting adjusting gear post 306 rotates synchronously with the rotating shaft 305 and the limiting gear post 303. After adjustment, the toothed sleeve 304 is slid to engage with the adjusting gear post 306 and the limiting gear post 303, completing the locking process after rotational adjustment. Welding can then continue.

[0037] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
