Description

Technical Field

[0001] The present application relates to the technical field of thickness detection of bracket assembly molded parts after welding, and in particular to a device for detecting thickness consistency of bracket assembly molded parts after assembly and welding. Background Art

[0002] Automotive bracket assembly molded parts are metal stampings that constitute automotive components. Metal sheets (such as steel and alloys) are formed into specific shapes and sizes through a stamping process. These stampings are widely used in automobiles, including body structural parts (such as left / right front fenders, left / right side outer panels, rear side panels, four doors, roofs, trunk panels, floors, and front panels), coverings (such as hoods, door panels, and bumpers), and interior parts (such as seat frames and instrument panel brackets).

[0003] After the bracket assembly is manufactured, it is necessary to connect them into a complete body structure through welding, which is crucial to ensure the strength and rigidity of the body. Figure 1 The bracket assembly molded part used on the instrument bracket (cross beam) shown in the figure includes an upper molded part and a lower molded part with right-angled flanges. The upper and lower molded parts are welded together at the sides to form an integral part. Currently, the stamped upper and lower molded parts are welded to the designed positions on the instrument cross beam, and then the upper and lower molded parts are welded together at the position where the flanges meet, such as Figure 2 As shown, the molded integral part.

[0004] During the welding process at the position where the flanges of the upper and lower molded parts meet, since the molded parts are usually made of thin plates, they will be slightly deformed by the high temperature of welding, which will affect the change of the position of the upper and lower molded parts. Figure 3 The upper molded part is shown as having an overall deflection compared to the lower molded part, and the upper molded part has a localized deformed convex surface. Figure 4 As shown, these will affect the overall side thickness of the upper and lower molded parts after welding, which will lead to problems in smooth assembly during the later assembly of the instrument crossbeam. Products will then be identified as unqualified and need to be returned to the factory for repair, which will have a significant impact on the efficiency of the assembly operation and the cost of returning to the factory for repair. Therefore, it is necessary to strictly control the thickness of the molded parts after welding during the production process. Summary of the Invention

[0005] In response to the above-mentioned problems, the present application aims to provide a thickness consistency detection device for the bracket assembly molded parts after assembly and welding. When used, the device can smoothly determine whether the thickness of the side of the integral part after welding meets the requirements, thereby effectively avoiding the impact caused in the later assembly process and improving the welding quality of the bracket assembly molded parts and the consistency of batch processing.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a device for detecting the thickness consistency of the bracket assembly molded parts after assembly and welding, the bracket assembly molded parts include an upper molded part and a lower molded part with right-angled flanges, and the upper molded part and the lower molded part are welded together at the side to form an integral part, which is characterized in that: the detection device is covered on the side located at the welding point of the integral part, and moves along the length direction of the side and detaches from the side.

[0007] Preferably, the detection device includes an operating handle, and a detection block with a U-shaped groove is provided at one end of the operating handle, and the inner width of the U-shaped groove is consistent with the side thickness of a standard integral part.

[0008] Preferably, one side edge of the detection block is set as a hinged edge, and a pressing portion extends from the tail section of the hinged edge, and a limit block is provided on the inner side of the hinged edge, which contacts the bottom surface of the U-shaped groove when it is parallel to the other side edge of the detection block.

[0009] Preferably, a slope structure is provided on one side of the U-shaped groove.

[0010] The beneficial effect of the present application is that the detection device is wrapped around the side of the integral part when in use. During the movement along the length of the side, if there is a change in thickness of the side, it will cause a jamming effect on the movement of the detection device, and then it can be smoothly judged whether the thickness of the side of the integral part after welding meets the requirements, thereby effectively avoiding the impact caused in the later assembly process, and improving the welding quality of the bracket assembly molded parts and the consistency of batch processing.

[0024] In order to enable ordinary technicians in this field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Refer to the attached Figures 1 to 12 The device shown is a device for testing the thickness consistency of bracket assembly molded parts after assembly and welding. The bracket assembly molded parts include an upper molded part 11 and a lower molded part 12 with right-angled flanges. The upper molded part 11 and the lower molded part 12 are welded together at the sides to form an integral part 1. Currently, the stamped upper molded part 11 and the lower molded part 12 are each welded to the designed position on the instrument crossbeam, and then the upper molded part 11 and the lower molded part 12 are welded together at the position where the flanges meet, such as Figure 2 As shown, the integral part 1 is formed.

[0026] In order to solve the problem that during the welding process at the position where the flanges of the upper molded part 11 and the lower molded part 12 meet, the thickness of the molded part side changes due to the influence of the high temperature of welding, which affects the subsequent assembly and return to the factory for repair, the present application designs a thickness consistency detection device. The detection device is covered on the side 1a at the welding position of the integral part 1, and moves along the full length of the side 1a and detaches from the side 1a. When the monitoring device is used, it is covered on the side 1a of the integral part 1. During the movement along the full length of the side 1a, if the thickness of the side 1a changes, it will cause a jamming effect on the movement of the detection device, and then it can be smoothly judged whether the thickness of the side 1a of the integral part 1 after welding meets the requirements, thereby effectively avoiding the impact caused in the later assembly process and improving the welding quality of the bracket assembly molded parts and the consistency of batch processing.

[0027] Specifically, such as Figure 5 As shown, the detection device includes an operating handle 2, and a detection block 3 with a U-shaped groove 3a is provided at one end of the operating handle 2. The inner width of the U-shaped groove 3a is consistent with the thickness of the side 1a of the standard integral part 1. During the detection operation, the operator holds the operating handle 2 and inserts the detection block 3 from one end of the side 1a through the U-shaped groove 3a. Figure 6-7 As shown, the inspection block 3 is moved at a constant speed along the length of side 1a. The inner width of the U-shaped groove 3a is used to test the overall thickness of side panel 1a. If the inspection block 3 becomes stuck on side 1a, it indicates that side 1a has been deformed during the welding process. The stuck location is marked and repaired on-site to avoid unusable parts during assembly. If the inspection block 3 can be removed from side 1a smoothly, it proves that the thickness of side 1a has not been deformed by welding and the part is considered qualified.

[0028] In the process of detecting the thickness of the side 1a by the detection block 3, if the thickness of the side 1a increases, the detection block 3 will be stuck. Figure 8 As shown, the detection block 3 has a certain moving speed during the operation, which causes the detection block 3 to be stuck on the raised position of the side 1a and difficult to be smoothly separated. When the detection block 3 is hard separated, it is easy to scratch the surface of the side 1a. Therefore, in order to solve this problem, Figure 9-11 As shown, one side of the detection block 3 is configured as a hinged edge 31, and a pressing portion 32 extends from the end of the hinged edge 31. A stopper 33 is provided on the inner side of the hinged edge 31, which contacts the inner bottom surface of the U-shaped groove 3a when the hinged edge is parallel to the other side of the detection block 3. A torsion spring (not shown) is provided at the hinge of the hinged edge. Under the limiting action of the torsion spring and the stopper 33, the hinged edge 31 and the other side of the detection block 3 are kept in a horizontal state. In this state, the hinged edge 31 is moved on the side 1a to perform thickness detection.

[0029] When the detection block 3 is stuck at the deformed protrusion of the side 1a, the place is marked, and then the pressing part 32 is pressed to overcome the force of the torsion spring, so that the hinged edge 31 flips upward and breaks away from the contact with the surface of the side 1a, so that the detection block 3 can be smoothly detached from the side 1a and the scratch problem on the surface of the side 1a can be avoided.

[0030] Since the inner width of the U-shaped groove 3a is equivalent to the standard thickness of the side 1a, in order to facilitate the detection block 3 to be smoothly inserted from the end of the side 1a for detection operation, Figure 12 As shown, a slope structure is provided on one side of the U-shaped groove 3a. The slope structure can increase the opening width of one side of the U-shaped groove 3a, making it easier for the detection block 3 to be smoothly inserted from the end of the side 1a, thereby improving detection efficiency and convenience of operation.

[0031] The principle of this application is as follows: when the thickness of the side panel 1a is inspected after the welding of the bracket assembly is completed, the operator grasps the operating handle 2, inserts the inspection block 3 through the U-shaped groove 3a from one end of the side panel 1a, and moves the inspection block 3 at a constant speed along the length of the side panel 1a. The inner width of the U-shaped groove 3a is used to inspect the thickness of the side panel 1a. If the inspection block 3 is stuck while moving on the side panel 1a, it proves that the side panel 1a has been deformed during the welding process. The stuck position is marked. Then, by pressing the pressing portion 32, the force of the torsion spring is overcome, causing the hinged edge 31 to flip upward and break away from the contact with the surface of the side panel 1a. This allows the inspection block 3 to be smoothly removed from the side panel 1a, and the deformed position can be repaired on site to avoid the impact of unusability during delivery to the final assembly line. If the inspection block 3 can be smoothly removed from the side panel 1a, it proves that the thickness of the side panel 1a has not been deformed due to welding, and it can be judged as a qualified product.

[0032] The above shows and describes the basic principles, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will also have various changes and improvements, which fall within the scope of this application.
