DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3The utility model provides a technical solution: a welding tool for a rear floor assembly of a vehicle, comprising a base plate 1, a lifting component 200 for height adjustment is installed on the top of the base plate 1, and an adjusting clamping mechanism 300 for spacing adjustment and clamping and fixing is installed at the end of the lifting component 200; through the coordinated use between the lifting component 200 on the top of the base plate 1 and the adjusting clamping mechanism 300, the clamping spacing can be easily adjusted, so that it can be suitable for clamping workpieces of different lengths, so that the practicality of the welding tool is further improved, so that the rear floor of the vehicle can be more conveniently welded and assembled, and the overall scope of application is improved. It can also improve the stability of clamping rotation, so that the welding work can be carried out stably and efficiently.

[0024] In this embodiment, the adjustable clamping mechanism 300 is a structure used to conveniently adjust the clamping distance and stably clamp the workpiece.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the adjustment clamping mechanism 300 includes a fixed box 301, two support seats 302 fixed inside the fixed box 301, a first drive motor 303 fixedly installed on the inner side of the fixed box 301, a bidirectional screw rod 304 rotatably connected between opposite sides of the two support seats 302 through a bearing, an auxiliary rod 305 fixed between opposite sides of the two support seats 302, two adjustment blocks 306 threadedly connected to the outer side of the bidirectional screw rod 304, a mounting plate 307 fixed to the bottom of the adjustment block 306, two linear slides 308 respectively fixed to opposite sides of the two mounting plates 307, two drive rods 309 respectively rotatably connected to opposite sides of the two mounting plates 307 through bearings, two rotating plates 310 respectively fixed to opposite ends of the two drive rods 309, two clamping assemblies respectively installed on opposite sides of the two rotating plates 310 and used for clamping and fixing, a fixed frame 315 fixed to the right side of the right mounting plate 307, and a second drive motor 316 fixedly installed on the inner side of the fixed frame 315.

[0026] It should be noted that the output shaft of the first drive motor 303 passes through the left side of the left support seat 302 and is fixedly connected to the left end of the bidirectional screw rod 304, so that the first drive motor 303 can drive the bidirectional screw rod 304 to rotate. The first drive motor 303 can be a servo motor.

[0027] At the same time, the right end of the auxiliary rod 305 passes through the two adjustment blocks 306 in sequence, and the bottom of the fixed box 301 is provided with adjustment holes for the two adjustment blocks 306 to slide. The two adjustment blocks 306 are symmetrically distributed on the left and right, so that the auxiliary rod 305 can limit the two adjustment blocks 306, so that the two adjustment blocks 306 can be driven to move under the rotation thrust of the outer thread of the two-way screw rod 304, and the two threads carried on the outer side of the two-way screw rod 304 can simultaneously drive the two symmetrically distributed adjustment blocks 306 to move towards and away from each other.

[0028] In addition, the opposite ends of the two driving rods 309 respectively pass through the corresponding mounting plates 307 and the linear slides 308 in sequence, so that the linear slides 308 can play a role in auxiliary support and limitation for the outer side of the end of the driving rod 309, thereby increasing the support stability of the other end of the driving rod 309, so that the clamped workpiece can be stably welded and rotated, and the fixed frame 315 is located between the right driving rod 309 and the outer side of the linear slide 308, and the output shaft of the second driving motor 316 is fixedly connected to the right end of the right driving rod 309, so that the second driving motor 316 can drive the right driving rod 309 to rotate, and the second driving motor 316 can be a servo motor.

[0029] In this embodiment, the clamping assembly is a structure used to stably clamp the workpiece.

[0030] like Figure 2 and Figure 3 As shown, the two clamping assemblies include two fixed pressure plates 311 respectively fixed to the opposite sides of the two rotating plates 310, two connecting blocks 312 respectively fixed to the opposite sides of the two rotating plates 310, two second linear drive mechanisms 313 fixedly installed on the opposite sides of the two connecting blocks 312, and a movable pressure plate 314 fixed to the output end of the second linear drive mechanism 313.

[0031] It should be noted that the second linear drive mechanism 313 can be a device with linear drive capability such as an electric push rod. The top of the fixed pressure plate 311 and the bottom of the movable pressure plate 314 are both bonded with anti-slip pads. The anti-slip pads can be rubber pads or other structures with a certain anti-slip effect and elasticity. The position of the movable pressure plate 314 corresponds to the position of the fixed pressure plate 311 on the same side, so that the workpiece can be stably clamped between the fixed pressure plate 311 and the opposite side of the movable pressure plate 314, and can play a role of flexible clamping, which is convenient for the staff to hold the welding gun for welding work.

[0032] In this embodiment, the lifting assembly 200 is a structure for performing smooth height adjustment.

[0033] like Figure 1As shown, the lifting assembly 200 includes two support columns 201 fixed on the top of the base plate 1, a support plate 202 fixed between the tops of the two support columns 201, a first linear drive mechanism 203 passing through and fixed on the top of the support plate 202, two sliding blocks 204 respectively fixed on the left and right sides of the fixed box 301, two sliding grooves 205 respectively opened on the opposite sides of the two support columns 201 and for the corresponding sliding blocks 204 to slide, and a positioning rod 206 fixed on the inner side of the sliding groove 205.

[0034] It should be noted that the output shaft of the first linear drive mechanism 203 passes through the top of the support plate 202 and is fixedly connected to the top of the fixed box 301. The fixed box 301 is located between the opposite sides of the two support columns 201, so that the first linear drive mechanism 203 can drive the fixed box 301 to perform stable lifting and lowering adjustments.

[0035] In addition, the first linear drive mechanism 203 can be a device with linear drive capability such as a cylinder. The bottom end of the positioning rod 206 passes through the top of the corresponding sliding block 204, so that the sliding block 204 can stably slide up and down on the inner side of the sliding groove 205 under the limiting action of the corresponding positioning rod 206.

[0036] The working principle of the above embodiment is:

[0037] When welding and assembling the rear floor of the vehicle, the first drive motor 303 is started to drive the bidirectional screw rod 304 to rotate. Under the limiting action of the auxiliary rod 305, the two adjustment blocks 306 move closer to or away from each other, so that the corresponding fixed pressure plate 311 can be driven to move and adjust the position through the mounting plate 307, so that the position of the fixed pressure plates 311 on both sides can be adaptively changed, and the workpiece is placed between the tops of the two fixed pressure plates 311, and the two second linear drive mechanisms 313 are started to drive the movable pressure plate 314 to move downward, and the workpiece can be moved between the movable pressure plate 314 and the fixed pressure plate 311. The workpiece is stably clamped and fixed by the cooperative clamping action. Starting the first linear drive mechanism 203 can drive the fixed box 301 to move up and down smoothly under the sliding cooperation between the two sliding blocks 204 and the two positioning rods 206 to achieve the function of height adjustment. Starting the second drive motor 316 drives the right drive rod 309 to rotate, so that the rotating plate 310 on the right rotates. The workpiece is driven to rotate by the clamping and fixing action between the fixed pressure plate 311 and the movable pressure plate 314 on the right, and the rotation action of the workpiece can be completed. The welding work can be carried out efficiently by holding the welding gun, which is convenient for the normal progress of the welding work.

[0038] Compared with the prior art, the rear floor assembly welding tooling of the vehicle facilitates easy adjustment of the clamping distance through the coordinated use of the lifting component 200 on the top of the bottom plate 1 and the adjusting clamping mechanism 300, so that it can be suitable for clamping workpieces of different lengths, thereby further improving the practicality of the welding tooling, allowing the rear floor of the vehicle to be more conveniently welded and assembled, thereby improving the overall scope of application, and also improving the stability of the clamping rotation, so that the welding work can be carried out stably and efficiently, thereby solving the problem that the existing automobile rear floor assembly welding tooling cannot easily adjust the clamping distance.

The main controller can be a conventional known device for control such as a computer, which can be realized through simple programming by technicians in the field. They are all existing public power connection technologies and will not be described in detail in the article.

[0040] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
