Guide grooves are respectively provided in the first profiling guide block 6 and the second profiling guide block 8 for fitting the vehicle body; a sliding positioning component 10 is further arranged on the side of the second profiling guide block 8. The sliding positioning component 10 and the guide groove in the second profiling guide block 8 cooperate to clamp the flange on the vehicle body together; the marking device for the front suspension of a passenger car further includes a control component 17, and the control component 17 is communicatively connected with the first sensor 4 and the main positioning component 3.

[0034] The present invention relates to a marking device for a passenger car front suspension. First, move the marking device to the upper side of the vehicle body, fit the first profiling guide block 6 and the second profiling guide block 8 to the corresponding positions of the vehicle body, insert the main positioning component 3 and the auxiliary positioning pin 5 of the marking device into the matching main positioning hole and auxiliary positioning hole, and then control the sliding positioning component 10 to work. The sliding positioning component 10 cooperates with the guide groove in the second profiling guide block 8 to clamp the flange on the passenger car front suspension. At this time, the marking device is accurately positioned on the vehicle body, and then subsequent marking operations can be carried out.

[0035] Preferably, as Figure 1 shown, a handle 12 is further provided on the rear end face of the frame 1. A clamping button 13 for controlling the main positioning component 3 is provided on the handle 12. The handle 12 facilitates manual movement of the marking device. A quick-change disk 11 is provided on the lower side of the handle 12. The left end face of the quick-change disk 11 is used to connect to the robotic arm.

[0036] Furthermore, as Figure 1 、 Figure 3 、 Figure 4 shown, a position adjustment component is further provided between the quick-change disk 11 and the frame 1. The position adjustment component includes a connecting arm 701, a rotary adjustment block 702, a horizontal shaft 703, and a vertical shaft 704. The front end of the horizontal shaft 703 is fixed on the rear side surface of the frame 1.

The left end of the connecting arm 701 is fixedly connected to the quick-change disk 11.

[0037] Furthermore, as Figure 1 shown, a groove is opened in the middle position of the right end of the connecting arm 701 where it is connected to the rotary adjustment block 702. The rotary adjustment block 702 is hinged in the groove through the vertical shaft 704. A vertical shaft locking member 706 is fixed on the right side surface of the groove for locking the rotation angle between the connecting arm 701 and the rotary adjustment block 702; a horizontal shaft locking member 705 is provided on the right side surface of the rotary adjustment block 702 for locking the rotation angle between the rotary adjustment block 702 and the frame 1. A plurality of vertical locking grooves are opened in the vertical shaft locking member 706 in the up and down direction, and a plurality of adjustment block limiting holes are opened on the top surface of the rotary adjustment block 702. A locking pin is provided between the vertical locking groove and the adjustment block limiting hole. When the connecting arm 701 and the rotary adjustment block 702 rotate through the vertical shaft 704, the vertical locking groove is aligned with different adjustment block limiting holes, and then the angle is locked by screwing in the locking pin.

[0038] Correspondingly, a horizontal shaft locking member 705 is fastened to the right side surface of the rotation adjustment block 702 by screws. A number of horizontal locking grooves are formed in the horizontal shaft locking member 705 in the front-rear direction, and a number of rack limiting holes are formed in the rear end surface of the rack 1. A locking pin is arranged between the horizontal locking groove and different rack limiting holes. When the rotation adjustment block 702 rotates with respect to the rack 1 through the horizontal shaft 703, the horizontal locking groove aligns with different rack limiting holes, and then the locking pin is screwed in to lock the angle. The present invention is provided with a horizontal shaft locking member 705 and a vertical shaft locking member 706, which are used to finely adjust the position of the marking device when the marking device is moved above the vehicle body, so that the first profiling guide block 6 and the second profiling guide block 8 are completely attached to the corresponding positions of the vehicle body, ensuring the accuracy of marking.

[0039] Preferably, as Figure 2 , Figure 3 shown, the sliding positioning assembly 10 includes a slide rail 1003 fixed to the bottom surface of the rack 1, a slider 1002 slidably arranged on the slide rail 1003, and a sliding drive source 1001 fixed to the bottom surface of the rack 1. The sliding drive source 1001 is in transmission connection with the slider 1002, and a second sensor 9 is also fixedly connected to the slider 1002; the control assembly 17 is in communication connection with the second sensor 9. In this embodiment, the sliding drive source 1001 adopts a cylinder, the piston end of the cylinder penetrates through the second profiling guide block 8 from left to right, and the slider 1002 is fastened to the piston end of the cylinder by screws. In this embodiment, a connecting block is further arranged between the slider 1002 and the slide rail 1003. The upper end of the connecting block is slidably engaged with the slide rail 1003, the lower end of the connecting block extends in the front-rear direction, and the number of the sliders 1002 is two and they are respectively arranged at the front and rear ends of the connecting block. As Figure 3 shown, after the flange on the vehicle body is clamped in the guide groove of the second profiling guide block 8, the piston end of the cylinder contracts to the right to pull the slider 1002 to move to the right. The left side surface of the flange abuts against the slider 1002, and the right side surface of the flange abuts against the second profiling guide block 8, so as to ensure the precise positioning of the marking device and the vehicle body. When the slider 1002 and the second profiling guide block 8 clamp the flange, the second sensor 9 arranged on the slider 1002 will also reach the preset position. At this time, the second sensor 9 feeds back a signal to the control assembly 17, and the control assembly 17 performs subsequent operations. In this embodiment, the left side surface of the second profiling guide block 8 abuts against the right side surface of the flange after being placed.

[0040] Preferably, as Figure 1As shown in the figure, the marking head 2 is a pneumatic marking head and is connected to a pneumatic pipeline, and a pressure gauge is connected to the pneumatic pipeline; the marking head 2 is communicatively connected to the control component 17. In this embodiment, the marking head 2 is similar to the body marking machine with the publication number CN203449760U applied by our company, but the length of the working part of the marking head 2 is 10 mm, which has a longer stroke compared with the working part of the marking head 2 in the prior art, effectively ensuring the quality of marking.

[0041] Preferably, as Figure 2 shown, the main positioning component 3 includes a fixed base 301, a sliding claw 302, and a claw driving component. The claw driving component drives the sliding claw 302 to slide on the fixed base 301, and the sliding claw 302 is clamped with the main positioning hole of the vehicle body; the claw driving component is communicatively connected to the control component 17. Further, in this embodiment, the shape of the fixed base 301 is circular, and the diameter is slightly smaller than the diameter of the main positioning hole. A sliding groove is provided on the fixed base 301, and the sliding claw 302 is slidably installed in the sliding groove. When the claw driving component drives the sliding claw 302 to move in the sliding groove, the outer peripheral surface of the sliding claw 302 abuts against the main positioning hole, so as to tension the main positioning component 3 in the main positioning hole. The claw driving component adopts a cylinder, and the clamping button 13 on the handle 12 is used to control the on-off of the air path in the claw driving component, so as to realize the tension of the main positioning component 3 in the main positioning hole.

[0042] Further, in this embodiment, the angle between the main positioning hole and the auxiliary positioning hole is a fixed value (the fixed value depends on the requirements of different vehicle bodies). During use, the fixed base 301 of the main positioning component 3 is first inserted into the main positioning hole, and then rotated around the fixed base 301 so that the auxiliary positioning pin 5 is inserted into the auxiliary positioning hole. At this time, the first sensor 4 beside the auxiliary positioning hole feeds back a position signal to the control component 17, and the control component 17 reminds the personnel to further operate. The personnel press the clamping button 13 to realize the tension of the main positioning component 3 in the main positioning hole. At the same time, the main positioning component 3 and the auxiliary positioning pin 5 are provided, and the angle between the main positioning component 3 and the auxiliary positioning pin 5 is a fixed value, effectively avoiding the rotational movement of the marking device around the fixed base 301.

[0043] Further, to prevent the frame 1 from colliding with the vehicle body, an anti-collision block 14 is also provided on the rear side surface of the frame 1. The anti-collision block 14 is made of nylon material, effectively reducing the collision between the frame 1 and the vehicle body. The control component 17 is arranged on the rear side surface of the frame 1, and the control component 17 is located below the handle 12, which can make full use of the space of the frame 1.

[0047] A3: Drag the marking device downwards close to the vehicle body through the handle 12, and the first profiling guide block 6 and the second profiling guide block 8 are abutted against the corresponding positions of the vehicle body; then insert the fixed base 301 of the main positioning component 3 into the corresponding main positioning hole, and rotate at a certain angle with the fixed base 301 as the axis, so that the auxiliary positioning pin 5 is inserted into the corresponding auxiliary positioning hole of the vehicle body; at this time, the first sensor 4 reaches the predetermined position, and the first sensor 4 feeds back information to the control component 17;

[0048] A4: The control component 17 receives the information fed back by the first sensor 4 and reminds the operator that the next operation can be carried out; the operator controls the movement of the sliding claw 302 in the fixed base 301 through the clamping button 13 set on the handle 12 to realize the tensioning of the sliding claw 302 in the main positioning hole;

[0049] A5: In step A4, while the control component 17 reminds the operator to carry out the next operation, it controls the sliding positioning component 10 to work. The slider 1002 in the sliding positioning component 10 moves on the slide rail 1003, and the slider 1002 cooperates with the second profiling guide block 8 to clamp the flange at the corresponding position of the vehicle body. At this time, the second sensor 9 follows the slider 1002 to reach the predetermined position, and the second sensor 9 feeds back information to the control component 17;

[0050] A6: The control component 17 receives the information fed back by the second sensor 9 and controls the operation of the marking head 2. The marking head 2 reads the marking parameters in the control component 17 and marks the vehicle body;

[0051] A7: After the marking is completed, the control component 17 automatically controls the marking head 2 to stop, and then reversely controls the sliding positioning component 10. The slider 1002 of the sliding positioning component 10 is separated from the flange of the vehicle body; then the operator operates the clamping button 13 to make the sliding claw 302 move in the fixed base 301, and the sliding claw 302 is disengaged from the main positioning hole. The operator lifts the marking device upwards through the handle 12, and then moves the marking device out to the left through the robotic arm;

[0052] A8: Wait for the arrival of the next vehicle body, and then repeat steps A2 - A7.

[0053] Preferably, step A1 is the initialization setting of the marking device, which only needs to be set once.

[0054] Preferably, in step A3, when the operator fits the first profiling guide block 6 and the second profiling guide block 8 to the corresponding positions of the vehicle body, the angle between the marking device and the robotic arm can be adjusted through the vertical axis 704 and the horizontal axis 703 according to the actual position of the marking device, so as to ensure the accuracy of the marking device.
