Description

Technical Field

[0001] The present application relates to the technical field of clamping tooling, and in particular to a fender contour clamping tooling. Background Art

[0002] The fender is an important part of the car body. It is used to cover the wheels. It is named after its shape and position resembling bird wings. It is divided into front fenders and rear fenders. The front fenders are set on both sides of the car side panels near the front wheels, and the rear fenders are set on both sides of the car side panels near the rear wheels. The front and rear fenders play a role in protecting the wheel arches of the car and preventing sand, gravel and mud from splashing onto the bottom of the car. As an important part of the car body structure, the car side panels are located on the side of the car body, usually covering the doors, side windshields, windows and the side surrounds of the car body. They not only have functions such as windproof, rainproof and noiseproof, but also provide additional protection in the event of a collision.

[0003] In the existing automobile manufacturing and assembly technology, the fender is installed on the side panel of the car through the fender clamping tool, which plays the role of stably installing the fender in place. However, there are some problems with the current technology. Specifically, during assembly, employees need to control the position of the fender with one hand, adjust the gap surface difference between the fender surface and the reference surface of the tooling, and operate the wrench with the other hand to tighten the fender fixing bolts. In this operation method, during the tightening process, the employee's hand controlling the fender needs to accurately grasp the positioning of the fender in multiple directions, and will also be affected by the reaction force of the tool, which can easily cause the position of the fender to shift. Therefore, although the clamping tool has been used, after the fender is installed, additional adjustments are still required online or after the vehicle is offline to ensure the accuracy of the fender position.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] An embodiment of the present application provides a fender contour clamping tool for improving the efficiency and accuracy of fender installation. The fender contour clamping tool includes a frame 100, a first limiting assembly 200 and a contour installation assembly 400.

[0032] The rack 100 is fixedly mounted on a mounting base; illustratively, the mounting base includes but is not limited to a car side panel, a ground reference entity, etc. The mounting base can provide a mounting position for the rack 100. The following takes the mounting base as a car side panel as an example to describe the technical solution of the present application.

[0033] The first stopper assembly 200 is used to fix the rack 100 on the installation base. Figure 1 As shown, the first limiting assembly 200 includes a fixing clip 210, and the fixing clip 210 is disposed on the frame 100. Exemplarily, the fixing clip 210 is fixed on the frame 100 by welding, bolt connection, clamping, gluing or riveting.

[0034] The rack 100 is fixedly connected to the installation base via the fixing clamp 210. For example, during use, the fixing clamp 210 clamps the installation base so that the fixing clamp 210 is fixedly connected to the installation base, thereby fixing the rack 100 on the installation base.

[0035] The number of the fixing clips 210 is at least two. For example, two fixing clips 210 are provided. In another embodiment, three fixing clips 210 are provided. In another embodiment, four fixing clips 210 are provided. Of course, five, six, or seven fixing clips 210 may also be provided.

[0036] The contour mounting assembly 400 is disposed on the frame 100 for clamping the workpiece 500 . The contour mounting assembly 400 includes a telescopic member 410 and a clamping block 420 .

[0037] like Figure 3 As shown, the telescopic member 410 is disposed on the frame 100 , and the telescopic member 410 can be telescoped along the X-axis direction.

[0038] like Figure 3 As shown, the clamping block 420 is disposed on the telescopic member 410 so that the clamping block 420 moves along the X-axis direction through the telescopic member 410; Figure 1 and Figure 2 As shown, the clamping block 420 is used to clamp the workpiece 500. The clamping block 420 moves along the X-axis direction to drive the workpiece 500 to move along the X-axis direction to adjust the displacement of the workpiece 500. Exemplarily, the workpiece 500 includes but is not limited to: a fender or other plate body, such as a door panel, etc. The technical solution of the present application is described below by taking the workpiece 500 as a fender as an example.

[0039] During use, the frame 100 is first fixed to the installation base by the fixing clamp 210, and then the workpiece 500 is clamped to the clamping block 420. The employee only needs to use one hand to pull the workpiece 500 or the clamping block 420 to extend and retract the telescopic member 410. The telescopic member 410 is extended and retracted along the X-axis on the frame 100, thereby adjusting the position of the workpiece along the X-axis direction. The employee uses the other hand to use tools (bolts, etc.) to fix the workpiece 500 to the side panel. The employee does not need to control the displacement of the workpiece 500 in directions other than the X-axis. Compared with the prior art, the interference to the workpiece 500 during installation is reduced, so that the workpiece 500 does not need to further adjust the installation position in subsequent processes, thereby improving the installation accuracy and efficiency of the workpiece 500.

[0040] like Figure 3 As shown, in one embodiment, the telescopic member 410 includes a linear bearing seat 412 and a sliding rod 414.

[0041] like Figure 3 As shown, the linear bearing seat 412 is fixedly disposed on the frame 100; illustratively, the linear bearing seat 412 is fixedly disposed on the frame 100 by welding, gluing, clamping, riveting or bolting.

[0042] like Figure 3As shown, the sliding rod 414 is slidably installed on the linear bearing seat 412 along the X-axis so that the sliding rod 414 can slide along the X-axis direction. For example, the linear bearing seat 412 includes a linear bearing and a seat body. The seat body is fixedly installed on the frame 100, and the linear bearing is fixedly installed on the seat body. The linear bearing has a through hole, and the sliding rod 414 is slidably installed in the linear bearing. The inner wall of the linear bearing limits the displacement of the sliding rod 414 in the Y-axis and Z-axis directions, and the sliding rod 414 can only move along the X-axis.

[0043] Exemplarily, the X-axis, the Y-axis and the Z-axis are mutually perpendicular directions. In another embodiment, the angles between the X-axis, the Y-axis and the Z-axis directions may also be less than 90°.

[0044] The clamping block 420 is disposed on the sliding rod 414 , and the clamping block 420 is slidably mounted on the linear bearing seat 412 along the X-axis through the sliding rod 414 .

[0045] High-precision sliding along the X-axis direction is achieved through the cooperation of the linear bearing seat 412 and the sliding rod 414. The linear bearing can limit the position of the sliding rod 414 in the Y-axis and Z-axis directions, ensuring that the sliding rod 414 can only move in the X-axis direction, thereby improving the stability and accuracy of the sliding.

[0046] The sliding rod 414 can slide quickly along the X-axis direction, so that the clamping block 420 can be quickly moved to a desired position, thereby improving work efficiency.

[0047] like Figure 3 As shown, in one embodiment, the telescopic member 410 also includes a locking pin 416, which is slidably installed on the linear bearing seat 412 along a direction perpendicular to the X-axis. For example, the locking pin 416 is slidably installed on the linear bearing seat 412 along the Y-axis or Z-axis direction. Of course, the locking pin 416 can also be slidably installed on the linear bearing seat 412 along other directions perpendicular to the linear bearing seat 412.

[0048] A locking hole is provided on the sliding rod 414 , and the axis of the locking hole is arranged parallel to the axis of the locking pin 416 . The locking pin 416 is inserted into the corresponding locking hole to lock the sliding rod 414 and the linear bearing seat 412 .

[0049] By inserting the locking pin 416 , the sliding rod 414 and the linear bearing seat 412 can be firmly locked together to prevent the sliding rod 414 from unnecessary movement due to external force during operation, thereby ensuring the stability and accuracy of the position of the workpiece 500 .

[0050] The design of the locking pin 416 allows the position of the sliding rod 414 to be conveniently locked during the installation and commissioning of the workpiece 500, thereby preventing the workpiece 500 from being injured or damaged due to accidental movement, thereby improving work safety.

[0051] In one embodiment, the telescopic member 410 also includes a first elastic component, which can be telescopic and rebound. The first elastic component is arranged on the linear bearing seat 412, and the first elastic component can apply a force to the locking pin 416 to make the locking pin 416 approach the sliding rod 414.

[0052] The elastic force of the first elastic component can automatically push the locking pin 416 to move toward the sliding rod 414. When the sliding rod 414 reaches the preset position, the locking pin 416 can be easily and quickly inserted into the locking hole, thereby simplifying the locking operation and improving work efficiency.

[0053] Under the continuous elastic force of the first elastic component, the locking pin 416 can be more firmly retained in the locking hole, effectively preventing locking failure due to vibration or external force interference, thereby improving the overall stability of the mechanical structure.

[0054] The automatic locking function reduces the manual operation of employees, allowing employees to complete the installation and commissioning of the workpiece 500 more easily.

[0055] The first elastic component includes, but is not limited to, a coil spring, a butterfly spring, an annular spring, a leaf spring, a steel plate spring, a rubber spring, an air spring, and the like.

[0056] like Figure 3 As shown, in one embodiment, the number of contoured mounting assemblies 400 is at least two.

[0057] At least two contoured mounting assemblies 400 are distributed on the frame 100 along the arc-shaped mating surface 510 . The arc-shaped mating surface 510 is the end surface of the workpiece 500 and is located on a side close to the frame 100 .

[0058] Exemplarily, two contour mounting assemblies 400 are provided. In another embodiment, three contour mounting assemblies 400 are provided. In another embodiment, four contour mounting assemblies 400 are provided. In another embodiment, five contour mounting assemblies 400 are provided. Of course, six, seven, or eight contour mounting assemblies 400 may be provided.

[0059] The multiple contour mounting assemblies 400 can more comprehensively contact and support the workpiece 500, reduce the error caused by single-point contact, and thus improve the processing accuracy. In particular, when processing arc-shaped or curved workpieces 500, the multiple contour mounting assemblies 400 can more accurately match the shape of the workpiece 500, ensuring the consistency and accuracy of the processing.

[0060] By distributing a plurality of contoured mounting assemblies 400 along the arc-shaped mating surface 510 on the frame 100, the workpiece 500 can be more effectively fixed to prevent it from moving or deforming due to vibration or external force interference during the processing. This stability is crucial to ensuring processing quality and extending the service life of the mechanical structure.

[0061] The multiple contoured mounting assemblies 400 can more evenly distribute the force on the workpiece 500, reducing the stress concentration and deformation problems caused by excessive force on a single point. This optimization helps to extend the service life of the workpiece 500 and improve the processing quality.

[0062] like Figure 2 or Figure 4 As shown, in one embodiment, the first position limiting assembly 200 further includes a main positioning pin 230, which is fixedly arranged on the frame 100; illustratively, a positioning hole that cooperates with the main positioning pin 230 is arranged on the installation base. During use, the main positioning pin 230 can be inserted into the positioning hole first to pre-position the frame 100, so as to facilitate the clamping of the mounting base by the fixing clamp 210. This pre-positioning method can ensure the position accuracy of the frame 100 during the installation process, facilitate the subsequent clamping operation of the fixing clamp 210, and thus improve the installation accuracy of the entire mechanical structure.

[0063] The main locating pin 230 cooperates with the mounting base to limit the displacement of the rack 100 in the X-axis, Y-axis and Z-axis directions; this multi-dimensional restriction can effectively prevent the rack 100 from shaking or deflecting during installation and use, thereby enhancing the overall stability of the mechanical structure.

[0064] like Figure 2 As shown, the main positioning pin 230 is an elliptical cylindrical structure, which can limit the rotation of the rack 100. Exemplarily, the main positioning pin 230 is arranged on the rack 100 along the Y-axis direction.

[0065] like Figure 4 As shown, the outer wall of the main positioning pin 230 has a stepped surface, and the stepped surface of the main positioning pin 230 can limit the displacement of the main positioning pin 230 in the Y-axis direction, preventing the main positioning pin 230 from being over-inserted into the positioning hole. This design not only protects the main positioning pin 230 and the positioning hole from damage, but also ensures the correct matching clearance between the rack 100 and the installation base, avoiding installation problems caused by too tight or too loose matching.

[0066] like Figure 4 As shown, in one embodiment, the first limiting assembly 200 further includes a plug-in component 220 .

[0067] like Figure 4As shown, the connector 220 is disposed on the rack 100 , and the connector 220 cooperates with the mounting base to limit the rack 100 .

[0068] like Figure 4 As shown, the connector 220 includes a fixing sleeve 222 and an L-shaped latch 223 .

[0069] The fixing sleeve 222 is disposed on the frame 100 along the X-axis direction. The fixing sleeve 222 is threadedly matched with the frame 100 . A limiting groove is provided on the wall of the fixing sleeve 222 .

[0070] The L-shaped pin 223 includes a first pin body and a second pin body fixedly connected to each other vertically. The first pin body is slidably installed in the fixed sleeve 222 along the X-axis direction. The first pin body can slide out or retract into the fixed sleeve 222. The second pin body can be engaged with the limiting slot, and the inner wall of the limiting slot blocks the second pin body.

[0071] Exemplarily, a door hinge is provided on the mounting base, such as Figure 1 As shown, the first pin of the connector 220 is inserted into the gap between the door hinge and the mounting base, and the door hinge blocks the first pin to limit the displacement of the first pin in the Y-axis direction, thereby limiting the displacement of the frame 100 in the Y-axis direction.

[0072] like Figure 4 As shown, in one embodiment, the fender contour clamping tool further includes a second limiting assembly 300 , and the second limiting assembly 300 is used to limit the frame 100 , and further limit the workpiece 500 on the frame 100 .

[0073] The second limiting assembly 300 includes a first profiling block 310 , which is fixedly disposed on the frame 100 . Exemplarily, the first profiling block 310 is fixedly disposed on the frame 100 by welding, riveting, gluing or bolting.

[0074] The first contour block 310 can abut against the mounting base along the X-axis direction to limit the displacement of the frame 100 in the X-axis direction.

[0075] like Figure 4As shown, in one embodiment, the second position-limiting assembly 300 further includes a second profiling block 320, which is fixedly disposed on the frame 100. The second profiling block 320 can abut against the arc-shaped mating surface 510 of the workpiece 500 along the X-axis direction to limit the displacement of the workpiece 500 from the X-axis direction. More than two second profiling blocks 320 are provided, and illustratively, two second profiling blocks 320 are provided; in another embodiment, three second profiling blocks 320 are provided. In another embodiment, four second profiling blocks 320 are provided. In another embodiment, five second profiling blocks 320 are provided. Of course, six, seven, eight or nine second profiling blocks 320 may also be provided.

[0076] The arc-shaped matching surface 510 is an end surface of the workpiece 500 and is located at a side close to the frame 100 .

[0077] Exemplarily, the second contour block 320 is fixed on the frame 100 by welding, riveting, gluing or bolting.

[0078] like Figure 4 As shown, in one embodiment, the second limiting assembly 300 further includes a third profiling block 330, which is fixedly disposed on the frame 100. The third profiling block 330 can abut against the workpiece 500 along the Y-axis direction to limit the displacement of the workpiece 500 from the Y-axis direction.
