Description

Technical Field

[0001] The invention relates to the technical field of crossbeam assembly devices, and in particular to a riveting tool for a vehicle frame crossbeam. Background Art

[0002] The crossbeam assembly is composed of a crossbeam body and a bent connecting plate assembled by riveting or screwing. The crossbeam assembly is not only used to ensure the torsional rigidity of the frame and withstand longitudinal and lateral loads, but also supports other components on the vehicle. It is an important component of the chassis, so its assembly quality is very important.

[0003] The existing frame crossbeam assembly riveting device has unstable assembly quality and low qualification rate, and is not suitable for automatic riveting. The manual riveting workers have high labor intensity and low assembly efficiency. The existing technical solutions have the following deficiencies:

[0004] 1. The existing frame crossbeam assembly riveting device has poor versatility and cannot adapt to various forms of crossbeam riveting. However, the crossbeam has various forms and different dimensions. The rivet directions on the upper and lower surfaces may be consistent or opposite.

[0005] 2. When the riveting directions of the upper and lower surfaces of the beam are different, the workpiece needs to be rotated to expose its riveting points so that the robot can perform automatic riveting. When the existing frame beam assembly riveting device drives the beam to flip to the working surface, the rivets are easily fallen off, resulting in unstable riveting quality and low pass rate. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a riveting tool for a frame crossbeam which has a simple structure, strong versatility, stable riveting quality and high pass rate.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A riveting tool for a frame crossbeam, comprising two relatively arranged positioning plate assemblies and two relatively arranged positioner connecting plates to enclose and form a platform, which is used to position and fix the bent connecting plates and the crossbeam so that they can flip with the positioner, wherein both ends of one positioning plate assembly are connected to the slide rails on the two positioner connecting plates and are used to fix crossbeams of different sizes through sliding adjustment, and a rivet anti-drop assembly is provided on the positioning plate assembly, which is used to tighten the rivets between the bent connecting plate and the crossbeam to prevent the rivets from falling when the platform flips.

[0009] As a further improvement of the above technical solution:

[0010] The rivet anti-drop assembly includes a rotating shaft, a connecting part and an abutting part. One end of the rotating shaft is connected to a spinning drive member, and the other end is connected to the connecting part. The connecting part is hinged on the abutting part. The spinning drive member drives the rotating shaft to drive the connecting part to rotate to the rivet position in the stand and then presses down to make the abutting part press against the rivet.

[0011] The positioning plate assembly includes a mounting plate, a guide rail and a plurality of positioning clamping units for clamping the two ends of the bent connecting plate. The guide rail is arranged on the inner wall of the mounting plate along the length direction of the mounting plate. The positioning clamping unit can be slidably installed on the guide rail and is used to clamp and fix bent connecting plates of different sizes through sliding adjustment.

[0012] The positioning clamping unit includes a quick-release pad and a retractable pressing arm. The quick-release pad is detachably connected with a positioning pin for positioning and fixing the bent connecting plate. The pressing arm is connected to a retractable cylinder for driving the pressing arm to retract toward the mounting plate after the positioning pin is inserted into the bent connecting plate to press the bent connecting plate.

[0013] The quick-release backing plate is provided with a quick-release locking screw to connect the positioning pin.

[0014] The quick-release pad is provided with a plurality of quick-insertion blocks connected with the positioning pins for adapting to the bending connection plates at different angles. After the positioning pins are inserted into the quick-insertion blocks, the quick-release locking screws are rotated to realize quick connection.

[0015] Stoppers are provided at both ends of the guide rail to prevent the positioning clamping unit from sliding out of the guide rail.

[0016] A screw transmission assembly is provided on the positioner connecting plate to drive the slidable positioning plate assembly to slide. The screw transmission assembly includes a screw driving part fixed on the positioner connecting plate and a screw rod passed through the positioning plate assembly. The driving end of the screw driving part is connected to the screw rod and is used to drive the screw rod to rotate to drive the positioning plate assembly to slide along the slide rail.

[0017] The mounting plate is provided with a plurality of pin hole positioning blocks, which are used for inserting pins to limit the positioning clamping unit after the positioning clamping unit slides into place.

[0018] Both ends of the other non-slidable positioning plate assembly are fixedly connected to the two positioner connecting plates through right-angle fixing pieces.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. The present invention discloses a riveting tool for a vehicle frame crossbeam, wherein a platform formed by relatively arranged positioning plate assemblies and relatively arranged positioner connecting plates positions and fixes a bent connecting plate and a crossbeam. When the fixed bent connecting plate and the crossbeam have a plurality of riveting points with different riveting directions, the flip positioner drives the platform and the bent connecting plate and the crossbeam fixed on the platform to flip over, exposing the riveting points, so that a welding robot can perform riveting conveniently and quickly, and manual intervention for a continuous period of time can realize the interlaced placement of rivets on both sides of the crossbeam, thereby greatly improving the riveting efficiency and quality.

[0021] 2. The present invention discloses a riveting tool for a vehicle frame crossbeam, which connects the two ends of a positioning plate assembly to the slide rails of a positioner connecting plate that are relatively arranged, so that the positioning plate assembly can slide along the slide rails and can be flexibly adjusted according to the size of the crossbeam assembly, making the tool highly versatile.

[0022] 3. The present invention discloses a riveting tool for a vehicle frame crossbeam, which provides a rivet anti-drop assembly to press against the rivets between the bent connecting plate and the crossbeam to prevent the rivets from falling when the stand rotates, thereby improving the riveting efficiency and quality of the tool.

[0023] Fourth, the present invention discloses a riveting tool for a vehicle frame crossbeam, which includes a rivet anti-drop assembly consisting of a rotating shaft, a connecting part and an abutting part. Before the positioner drives the platform to rotate 0°, the spinning drive drives the rotating shaft to drive the connecting part to rotate to the rivet position in the platform, and then drives the connecting part to press down so that the connecting part abuts against the rivet. This prevents unwelded rivets from falling off during the rotation process when the platform is turned over, avoids adding the process of supplementing rivets, and greatly improves the riveting quality and efficiency.

[0024] 5. The present invention discloses a riveting tool for a frame crossbeam. By setting a positioning clamping unit that is slidably connected to a mounting plate, on the one hand, rapid positioning and connection of a bent connecting plate is achieved; on the other hand, it is suitable for bent connecting plates of various sizes, greatly improving the applicability of the device.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] In the present invention, unless otherwise clearly specified and limited, the terms "assemble", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] like Figures 1 to 4 As shown, the riveting tool for the frame crossbeam of this embodiment includes two relatively arranged positioning plate assemblies 31 and two relatively arranged positioner connecting plates 32 to enclose and form a platform 3, which is used to position and fix the bent connecting plate 2 and the crossbeam 1 so that they can flip with the positioner. Both ends of one positioning plate assembly 31 are connected to the slide rails 321 on the two positioner connecting plates 32, which are used to fix crossbeams 1 of different sizes through sliding adjustment. The positioning plate assembly 31 is provided with a rivet anti-drop assembly 33, which is used to tighten the rivets between the bent connecting plate 2 and the crossbeam 1 to prevent the rivets from falling when the platform 3 is flipped.

[0040] The specific implementation principle of the riveting tool for the frame crossbeam is as follows:

[0041] When the riveting tool for the frame crossbeam is used, first, the two bottom bent connecting plates 2 are fixed on the positioning plate assemblies 31 arranged oppositely. Then, according to the size of the crossbeam 1, one of the positioning plate assemblies 31 is driven to slide on the slide rail 321 until the two bent connecting plates 2 respectively bear the two ends of the crossbeam 1 and the riveting points correspond. The positioning plate assembly 31 is slidably connected with the positioner connecting plate 32 so that the tool is suitable for multi-size crossbeams 1. Further, after the crossbeam 1 is placed on the fixed bent connecting plate 2, the top two bent connecting plates 2 are fixed on the positioning plate assemblies 31 arranged oppositely, so that the top and bottom of the two ends of the crossbeam 1 are respectively abutted against the bent connecting plates 2. Then, rivets are placed at the riveting points of the crossbeam 1 and the top bent connecting plates 2 at both ends of the crossbeam 1, and the rivet anti-drop assembly 33 is driven to press against the rivets between the bent connecting plates 2 and the crossbeam 1 to prevent the rivets that have not been welded from falling when the stand 3 is turned over. After ensuring that the rivet anti-drop assembly 33 limits the rivet, the turning positioner is driven to turn the stand 3 and the bent connecting plate 2 and beam 1 fixed on the stand 3 together by 180°. At this time, the bent connecting plate 2 originally located at the bottom of the beam 1 is turned to the top, exposing the riveting point between the beam 1 and the bottom bent connecting plate 2, and rivets are placed at the riveting point. Finally, the workers are manually evacuated to a safe position, and the welding robot is started for automatic riveting. Then turn it back, remove the rivet anti-drop assembly 33, and weld the unwelded rivets.

[0042] Through the above special design, the riveting tool for the frame crossbeam has the following advantages:

[0043] 1. The stand 3 formed by the relatively arranged positioning plate assembly 31 and the relatively arranged positioner connecting plate 32 is used to position and fix the bent connecting plate 2 and the beam 1. When the fixed bent connecting plate 2 and the beam 1 have multiple rivet points with different riveting directions, the flip positioner drives the stand 3 and the bent connecting plate 2 and the beam 1 fixed on the stand 3 to flip over, exposing the rivet points, so that the welding robot can perform riveting conveniently and quickly. Only one continuous manual intervention is required to complete the insertion and placement of rivets on both sides of the beam 1, which greatly improves production safety and production efficiency.

[0044] Second, by setting the two ends of a positioning plate assembly 31 and the relatively arranged positioner connecting plate 32 to be slidably connected, the positioning plate assembly 31 can slide along the slide rail 321 and flexibly adjust according to the size of the beam assembly, so that the tooling has strong versatility.

[0045] 3. By providing a rivet anti-drop assembly 33 to press against the rivets between the bent connecting plate 2 and the crossbeam 1, the rivets are prevented from falling when the stand 3 rotates, thereby improving the riveting efficiency and quality of the tooling.

[0046] like Figure 1 and Figure 4As shown, in this embodiment, the rivet anti-drop assembly 33 includes a rotating shaft 331, a connecting portion 332 and an abutting portion 333. One end of the rotating shaft 331 is connected to the spinning drive member 334, and the other end is connected to the connecting portion 332. The abutting portion 333 is hinged on the connecting portion 332. The spinning drive member 334 drives the rotating shaft 331 to drive the connecting portion 332 to rotate to the rivet position in the stand 3, and then presses down to make the abutting portion 333 abut against the rivet. Before the positioner drives the stand 3 to rotate 180°, the spinning drive member 334 drives the rotating shaft 331 to drive the connecting portion 332 to rotate to the rivet position in the stand 3, and then drives the connecting portion 332 to press down, so that the connecting portion 332 abuts against the rivet. It prevents the unwelded rivets from falling off during the rotation process when the stand 3 is turned over, avoids adding the process of supplementing rivets, and greatly improves the riveting quality and efficiency.

[0047] like Figures 1 to 3 As shown, in this embodiment, the positioning plate assembly 31 includes a mounting plate 311, a guide rail 312 and a plurality of positioning clamping units 313 for clamping the two ends of the bent connecting plate 2. The guide rail 312 is arranged on the inner wall of the mounting plate 311 along the length direction of the mounting plate 311. The positioning clamping units 313 are slidably mounted on the guide rail 312 and are used to clamp and fix the bent connecting plates 2 of different sizes through sliding adjustment. According to the size of the bent connecting plate 2, the positioning clamping units 313 are driven to slide on the guide rail 312 on the mounting plate 311, so that the positioning clamping units 313 connect the two ends of the bent connecting plate 2 at the bottom of the beam 1, and the bent connecting plate 2 at the bottom is detachably connected to the mounting plate 311. The bent connecting plate 2 at the bottom is fixed to carry the beam 1, thereby improving the reliability of the tooling, and also providing a positioning basis for connecting the bent connecting plate 2 at the top, thereby improving the assembly efficiency. When the positioner rotates 180°, the clamping of the positioning clamping unit 313 is released, exposing the riveting points between the cross beam 1 and the bent connecting plate 2 to facilitate workers to insert rivets. By providing the positioning clamping unit 313 that is slidably connected to the mounting plate 311, on the one hand, the quick positioning and connection of the bent connecting plate 2 is achieved, and on the other hand, it is suitable for bent connecting plates 2 of multiple sizes, greatly improving the applicability of the device.

[0048] like Figures 1 to 3As shown, in this embodiment, the positioning clamping unit 313 includes a quick-release pad 3131 and a retractable pressing arm 3132. The quick-release pad 3131 is detachably connected with a positioning pin 3133 for positioning and fixing the bent connecting plate 2. The pressing arm 3132 is connected to a retractable cylinder for driving the pressing arm 3132 to retract toward the mounting plate 311 after the positioning pin 3133 is inserted into the bent connecting plate 2 to press the bent connecting plate 2. By setting the positioning clamping unit 313 to be detachably connected to the bent connecting plate 2, the positioning pin 3133 passes through the through hole of the bent connecting plate 2 to position and fix the bent connecting plate 2, and then the pressing arm 3132 is driven to retract toward the mounting plate 311 to press the bent connecting plate 2, further fixing the bent connecting plate 2 to prevent the bent connecting plate 2 from falling out, thereby improving the connection strength.

[0049] like Figure 3 As shown, in this embodiment, a quick release locking screw 3134 is provided on the quick release pad 3131 to connect the positioning pin 3133. By providing the quick release locking screw 3134, the positioning pins 3133 of different outer dimensions can be quickly disassembled and assembled to adapt to different bending connecting plates 2, thereby improving the applicability of the tooling.

[0050] like Figure 3 As shown, in this embodiment, a plurality of quick-insertion blocks (not shown in the figure) are provided on the quick-release pad 3131 and connected with the positioning pin 3133 to adapt to the bending connection plate 2 at different angles. After the positioning pin 3133 is inserted into the quick-insertion block, the quick-release locking screw 3134 is rotated to achieve quick connection. By providing a plurality of quick-insertion blocks connected with the positioning pin 3133 on the quick-release pad 3131 to adapt to the bending connection plate 2 at different angles, the applicability of the tooling is further improved.

[0051] like Figure 1 As shown, in this embodiment, stoppers 314 are provided at both ends of the guide rail 312 to prevent the positioning clamping unit 313 from sliding out of the guide rail 312. By providing the stoppers 314 to prevent the positioning clamping unit 313 from derailing and sliding out, the reliability of the tooling is greatly improved.

[0052] like Figure 1 and Figure 4As shown, in this embodiment, a screw drive assembly 4 is provided on the positioner connecting plate 32 to drive the slidable positioning plate assembly 31 to slide. The screw drive assembly 4 includes a screw drive member 42 fixed on the positioner connecting plate 32 and a screw 41 passing through the positioning plate assembly 31. The driving end of the screw drive member 42 is connected to the screw 41 and is used to drive the screw 41 to rotate so as to drive the positioning plate assembly 31 to slide along the slide rail 321. By setting the screw drive assembly 4 to drive the positioning plate assembly 31 to slide on the slide rail 321 to adapt to the size of the beam 1, the screw drive member 42 drives the screw 41 to rotate so as to drive the positioning plate assembly 31 to slide along the slide rail 321. The screw drive has strong stability and high precision, and can achieve the high positioning precision requirement of the tooling.

[0053] like Figure 2 As shown, in this embodiment, a plurality of pin hole positioning blocks 315 are provided on the mounting plate 311, which are used to insert pins to limit the positioning clamping unit 313 after the positioning clamping unit 313 slides into place. The pin hole positioning blocks 315 are provided to limit the positioning clamping unit 313 that has slid into place, so as to prevent the positioning clamping unit 313 from continuing to slide and causing positioning deviation of the bent connecting plate 2.

[0054] like Figure 1 and Figure 4 As shown, in this embodiment, both ends of the other non-slidable positioning plate assembly 31 are fixedly connected to the two positioner connecting plates 32 through right-angle fixing members 5. By providing right-angle fixing members 5 between the two positioner connecting plates 32 at both ends of the non-slidable positioning plate assembly 31 and improving the connection strength between the positioning plate assembly 31 and the positioner connecting plates 32, deformation of large-sized plates during use is avoided, and the reliability of the tooling is greatly improved.
