Description

Technical Field

[0001] This utility model relates to the field of inspection tooling, specifically an automotive longitudinal beam inspection tool. Background Technology

[0002] The automotive longitudinal beam is a channel-shaped beam. To facilitate the connection between the longitudinal beam and the rest of the vehicle chassis structure, several mounting holes are provided on both sides and the bottom surface of the longitudinal beam. To ensure that the longitudinal beam can be smoothly connected to the other structures during assembly, the positions of the mounting holes at different locations on the longitudinal beam need to be checked. The traditional inspection method involves positioning the ends of the beam using positioning components and then checking each mounting hole individually. Compared to using a single mounting hole as a reference for fixing the longitudinal beam, this method is more time-consuming and less efficient.

[0003] Therefore, it is necessary to provide an inspection tool for automotive longitudinal beams. Utility Model Content

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, an embodiment of this application provides an automotive longitudinal beam inspection fixture, including a frame 1, a support seat 2 mounted on the frame 1, a clamping member 3 mounted on the frame 1 for clamping the product 100, a side positioning member 4 mounted on the frame 1, a hole alignment detection member 5, and a reference clamping member located at one end of the support seat 2 mounted on the frame 1. Figure 3 As shown, the reference clamping component includes a left clamping support 6 and a right clamping support 7 mounted on the frame 1. The right clamping support 7 includes several nuts 71, a first seat 73 mounted on the frame 1, a first block 74 mounted on the first seat 73, a first slide rod 75 slidably connected to the first seat 73 in the left-right direction, a first support part 76 mounted at the end of the first slide rod 75, and a first elastic element 77 mounted on the first block 74 for fixing the first slide rod 75 and the first block 74. The first support part 76 is provided with a right support surface that matches the lower end face of the product 100 and a right limiting surface that matches the right side of the product 100. A positioning screw 72 is provided on the right limiting surface. Several first positioning holes are provided on the first support part 76. The positioning screw 72 passes through the first positioning holes and is threadedly connected to the nuts 71.

[0021] It should be noted that product 100 is a channel beam, and the side of the beam is provided with a No. 1 side hole that corresponds to the No. 1 positioning hole.

[0022] In actual use, after placing the product 100 on the support base 2, the end of the product 100 is first clamped by the reference clamping member, and then the product 100 is pressed by each clamping member 3. Subsequently, the product 100 is positioned and detected by the side positioning member 4. When the reference clamping component performs reference positioning on the product 100, the left clamping support 6 and the right clamping support 7 move towards each other to clamp both sides of the product 100. The clamping principle of the right clamping support 7 is as follows: First, push the first slide rod 75 away from the left clamping support 6. After the product 100 is supported by the support seat 2, push the slide rod towards the left clamping support 6. If the lower end face of the product 100 can be supported by the right support surface and the right side face of the product 100 can be contacted and limited by the right limiting surface, then try to pass the positioning screw 72 through the first positioning hole and then through the first side hole of the product 100. If the positioning screw 72 passes through the first side hole, lock it with the positioning screw 72 using the nut 71. Then, fix the first slide rod 75 and the first block 74 through the first elastic element 77 to achieve the reference positioning of the product 100.

[0023] In the above design, the structural design and specific implementation of the reference clamp can effectively achieve reference positioning of product 100, which facilitates subsequent inspection of product 100 and improves the inspection efficiency of product 100.

[0024] Specifically: such as Figure 3 As shown, the left clamping support member 6 includes several second-order insert rods 61, a second-order seat 62 mounted on the frame 1, a second-order block 63 mounted on the second-order seat 62, a second-order slide rod 64 slidably mounted on the second-order block 63, a second-order elastic member 65 mounted on the second-order block 63 for fixing the second-order slide rod 64 and the second-order block 63, and a second-order support part 66 mounted on the end of the second-order slide rod 64 opposite to the first-order slide rod 75. The second-order support part 66 is provided with a left support surface for supporting the bottom surface of the product 100 and a left limiting surface for abutting the left side of the product 100. Several second-order positioning holes are provided on the left support surface, and the second-order insert rods 61 are used to cooperate with the second-order positioning holes.

[0025] It should be noted that product 100 is provided with a bottom through hole that corresponds to the second positioning hole.

[0026] During actual testing, first slide the second slide rod 64 away from the right clamping support 7, then place the product 100 on the support seat 2, and then push the second slide rod 64 so that the second support part 66 contacts the product 100. Then fix the second slide rod 64 and the second block 63 by the second elastic element 65. After contact, try to insert the second insertion rod 61 through the bottom through hole into the second positioning hole. If it can enter the second positioning hole, the bottom through hole position is qualified; otherwise, it is unqualified.

[0027] In the above design, the structural design and specific implementation of the left clamping member can effectively support the product 100 and detect the position of the bottom through hole of the product 100.

[0028] Specifically: such as Figure 3 As shown, the first elastic element 77 and the second elastic element 65 have the same structure, the first slide rod 75 and the second slide rod 64 have the same structure, and the first block 74 and the second block 63 have the same structure. The first slide rod 75 is provided with a first hole and a second hole. The first block 74 is provided with a first sliding groove that is slidably connected to the first slide rod 75 and a side hole that communicates with the sliding groove. The first elastic element 77 includes a first spring 772 and a first pin 771 that is slidably connected to the first block 74 through the side hole. The two ends of the first spring 772 are respectively connected to the first pin 771 and the first block 74. The first pin 771 mates with either the first hole or the second hole. The first hole is located to the left of the second hole.

[0029] In actual use, taking the right clamping support 7 as an example: before the product 100 is placed on the support 2, the first slide rod 75 needs to be slid along the right side so that the first pin 771 engages with the first hole. After the product 100 is placed on the support 2, the pin is pulled out so that the first spring 772 is stretched. Then the first slide rod 75 is slid to the left so that the second hole aligns with the first pin 771. Then the first pin 771 is released so that the first spring 772 drives the first pin 771 to insert into the second hole.

[0030] In the above design, the structural design and specific implementation of the first elastic element 77 and the second elastic element 65 facilitate the positioning of the first slide rod 75 and the second slide rod 64.

[0031] Specifically: such as Figure 4 As shown, the clamping component 3 includes a No. 3 seat 31 mounted on the frame 1, a quick clamp 32 mounted on the No. 3 seat 31, and an L-shaped pressure bar 33 mounted on the quick clamp 32. The quick clamp 32 drives the L-shaped pressure bar 33 to press down on the product 100.

[0032] In actual use, before placing the product 100 on the support seat 2, the quick clamp 32 opens. After the product 100 is placed on the support seat 2, the quick clamp 32 lowers the L-shaped pressure strip 33 to press the product 100.

[0033] In the above design, the structural design and specific implementation of the clamping component 3 can effectively achieve rapid clamping and rapid release of the product 100 by utilizing the convenient tightening and loosening characteristics of the quick clamp 32. Specifically: such as Figure 5As shown, the side positioning component 4 includes a No. 4 seat 41 mounted on the frame 1, a rotating plate 42 mounted on the No. 4 seat 41, a No. 4 side plate 43 mounted on the rotating plate 42, several No. 4 positioning posts 44, and a knob bolt 45 mounted on the rotating plate 42. The No. 4 seat 41 is provided with a No. 4 screw hole that mates with the knob bolt 45.

[0034] It should be noted that the product 100 has a side through hole that can mate with the fourth positioning post 44. The frame 1 is provided with a placement platform 400 for placing the fourth positioning post 44. Because there are some protrusions on the outer side of the longitudinal beam, the rotating plate needs to be lowered to ensure that the longitudinal beam is placed on the support seat 2.

[0035] In actual use, before the product 100 is placed on the support base 2, the knob bolt 45 is not in contact with the No. 4 screw hole. At this time, the rotating plate 42 is in an inclined state. After the product 100 is placed on the support base 2, the rotating plate 42 is rotated upward to a vertical state, and then the knob bolt is rotated to lock with the No. 4 screw hole. If the No. 4 positioning post 44 can be inserted into the side through hole after the rotating plate 42 is rotated to a vertical state, then the side through hole position of the product 100 is qualified; otherwise, it is unqualified.

[0036] In the above design, the structural design of the side positioning component 4 and its specific implementation method enable rapid detection of the position of the through hole on the side of the longitudinal beam.

[0037] Specifically: such as Figure 1 and Figure 2 As shown, the hole alignment detection component 5 includes a No. 5 seat 51 mounted on the frame 1 and provided with a No. 5 slide groove, a No. 5 slide rod 52 slidably mounted on the No. 5 seat 51 via the No. 5 slide groove, a No. 5 positioning rod 53 mounted on the No. 5 slide rod 52, an annular protrusion 54 mounted on the No. 5 slide rod 52, and a limiting end 55 mounted on the side of the No. 5 slide rod 52 away from the product 100.

[0038] It should be noted that there should be two punched holes on both sides of the longitudinal beam, and they should be symmetrical.

[0039] In actual use, before placing product 100, slide slide rod 52 along slide groove 5 to align positioning hole 5 with product 100. After product 100 is in place, push slide rod 52 towards product 100. If positioning rod 53 can pass through both punches, it indicates that the two punches are aligned; otherwise, they are not aligned. Limiting end 55 and annular protrusion 54 prevent slide rod 52 from disengaging from seat 51.

[0040] In the above design, the structural design and specific implementation of the hole-to-detection component can effectively enable the inspection of the two punching positions of product 100.

[0041] Specifically: such as Figure 1 As shown, four casters 8 are provided below the frame 1.

[0042] In the above design, the universal wheels 8 are provided to facilitate the movement of the inspection tool of this application.

[0043] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
