Technical Field

[0001] The utility model relates to the field of automobile door sill beams, in particular to a riveted surface inspection tool for automobile door sill beams. Background Art

[0002] In traffic accidents, the probability of a car being hit head-on or sideways is very high. It is particularly important to ensure the safety of passengers when the car is hit head-on or sideways. The threshold beam is used to increase the strength of the door frame to withstand trampling, and also plays a decisive role in transmitting the frontal and side collision forces.

[0003] Threshold beam Figure 1 As shown, there are a plurality of riveted surfaces 42 , on which a plurality of riveted holes 421 are opened for riveting with the beam, and at the same time, process holes 41 are opened on each side of the sill beam 4 for releasing internal stress.

[0004] Since manual inspection of rivet holes is complicated, manufacturers often ignore the inspection step and directly install. If the position of the rivet holes is incorrect, it will cause problems with installation, and it will be necessary to spend effort to remove the threshold beam again. If forced installation, there will be safety hazards. Utility Model Content

[0008] The detection assembly includes multiple inspection tools, and the inspection tools include an inspection plate and a driving assembly. The driving assembly is used to drive the inspection plate to move back and forth between close to the corresponding riveted surface and away from the corresponding riveted surface. When the inspection plate is in a detection state, the inspection plate is arranged close to and parallel to the corresponding riveted surface. At least one through hole is opened on the inspection plate, and a measuring needle is slidably inserted in the through hole. The measuring needle is only used to be inserted into the corresponding riveted hole of the standard part, and multiple measuring needles are respectively used to detect multiple riveted holes.

[0009] Through the above technical solution, the operator can place the threshold beam on the bottom frame, and then limit the position of the threshold beam through the side positioning frame and the limiting structure. After the positioning is completed, the clamping mechanism drives the threshold beam from the other side to press against the side positioning frame, so that the threshold beam is fixed on the beam placement assembly; after fixation, the driving assembly drives the detection plate to move to the riveting surface, and then the operator can observe whether the measuring needle can pass through the corresponding riveting hole to know whether the riveting hole is standard.

[0010] Preferably, when the detection plate is in the detection state, the detection plate abuts against the riveted surface.

[0011] Through the above technical solution, the detection plate abuts against the riveted surface to facilitate the insertion of the measuring needle into the corresponding riveted hole that needs to be detected.

[0012] Preferably, the limiting structure includes a plurality of positioning rods, which are sequentially arranged on the side positioning frame, and the plurality of positioning rods respectively correspond to a plurality of process holes on the side of the door sill beam.

[0013] Through the above technical solution, multiple positioning rods can limit the movement of the threshold beam along the length direction. At the same time, the corresponding situation of the positioning rods and the process holes can enable the threshold beam to be placed on the beam assembly more accurately, thereby accurately obtaining the inspection result of the inspection fixture.

[0014] Preferably, the driving assembly includes a base, a movable rod and a locking piece. The bases on the multiple inspection fixtures are respectively arranged on the workbench and the side positioning frame. A groove is opened on the side of the base facing away from the threshold beam, and both ends of the groove pass through the base. One end of the movable rod rotates on the inner wall of the groove, and the other end of the movable rod is detachably connected to the detection plate. When the movable rod rotates toward the side of the threshold beam until it abuts against the bottom wall of the groove, the detection plate is in a detection state, and the locking piece is used to lock the state when the movable rod is rotated to abut against the bottom wall of the groove.

[0015] Through the above technical solution, the detection plate is rotatable on the base through the movable rod, and the design of the groove allows the movable rod to fit on the base, so that the base can limit the movement of the movable rod to facilitate detection.

[0016] Preferably, the locking member is a knob and a screw, one end of the screw is fixedly connected to the knob, and the other end is used to pass through the movable rod and then be threadedly connected to the base.

It also prevents the movable rod from directly hitting the workbench under the action of gravity and causing damage to the workpiece.

[0020] Preferably, the workbench is provided with a plurality of placement tables, and the top surfaces of the placement tables are provided with insertion holes for screws to be inserted.

A spring is sleeved on the measuring needle, and both ends of the spring are respectively abutted against the pressure plate and the detection plate. When there is no external force, the measuring needle is located on the outside of the threshold beam.

[0023] Through the above technical solution, the operator can push the pressure plate to move the probe toward the corresponding riveted hole to be tested. When not testing, the probe will be reset by the spring, and then the probe will be fixed above the test plate, without the operator having to move the probes back and forth between the storage place and the test plate one by one every time for testing.

[0025] Through the above technical solution, when the measuring needle is inserted into the corresponding rivet hole of the standard part, the pressure plate abuts against the top surface of the positioning column. At the same time, the pressure plate presses the push switch, and the detection light lights up. The operator can directly confirm whether the measuring needle is inserted into the rivet hole by the on and off of the detection light, thereby knowing whether the rivet hole is standard, avoiding the situation where the operator needs to observe with the naked eye whether the measuring needle is inserted into the rivet hole.

[0026] Preferably, a pull rod is provided on one side of the pressing plate, and the pull rod is used to assist an operator in moving the pressing plate.

[0027] Through the above technical solution, the operator can move the pressure plate toward the detection plate through the pull rod, so that the operator can directly pull down the pressure plate by standing on the side, thereby avoiding the operator having to push the pressure plate from above, which is more laborious.

The beam assembly 2 comprises a plurality of side positioning frames 21, a plurality of bottom frames 22 and a clamping mechanism 23. The side positioning frames 21 are used to abut the side of the threshold beam 4, the bottom frame 22 is used to abut the bottom of the threshold beam 4, the side positioning frames 21 are provided with a limiting structure 211 for limiting the sliding of the threshold beam 4 along the length direction, the clamping mechanism 23 comprises a plurality of quick clamps 231, and a plurality of quick clamps 2 31 is fixed on the workbench 1 by screws and is located on the side of the bottom frame 22 away from the side positioning frame 21. The clamping head of the quick clamp 231 moves toward the threshold beam 4, thereby driving the threshold beam 4 to press against the side positioning frame 21; the operator can place the threshold beam 4 on the bottom frame 22, and then limit the position of the threshold beam 4 through the side positioning frame 21 and the limiting structure 211. After the positioning is completed, the threshold beam 4 is driven from the other side to press against the side positioning frame 21 through the clamping mechanism 23, so that the threshold beam 4 is fixed on the beam setting assembly 2.

[0043] Reference Figure 1-Figure 7The detection assembly 3 includes a plurality of inspection fixtures 31, and the inspection fixture 31 includes an inspection plate 311 and a driving assembly 312. The driving assembly 312 is used to drive the inspection plate 311 to move back and forth between the corresponding riveted surface 42 and the corresponding riveted surface 42. When the inspection plate 311 is in the detection state, the inspection plate 311 abuts against the riveted surface 42 to facilitate the subsequent detection operation. At least one through hole is provided on the inspection plate 311, and a measuring pin 313 is slidably inserted at the through hole. The measuring pin 313 is only used to be inserted into the corresponding riveted hole 421 of the standard part, and the plurality of measuring pins 313 are respectively used to detect the plurality of riveted holes 421. After fixing the threshold beam 4, the driving assembly 312 drives the inspection plate 311 to move to the riveted surface 42. Then, the operator can observe whether the measuring pin 313 can pass through the corresponding riveted hole 421 to know whether the riveted hole 421 is standard, which simplifies the manual detection steps and reduces the workload of the operator.

[0044] Reference Figure 1-Figure 7 The limiting structure 211 includes a plurality of positioning rods 2111, which are sequentially inserted into the side positioning frame 21. The insertion of the plurality of positioning rods 2111 can limit the movement of the threshold beam 4 along the length direction. The plurality of positioning rods 2111 respectively correspond to a plurality of process holes 41 on the side of the threshold beam 4, so that the threshold beam 4 can be placed on the beam assembly 2 more accurately, thereby accurately obtaining the detection result of the inspection fixture 31.

[0045] Reference Figure 1-Figure 7 The driving assembly 312 includes a base 3121, a movable rod 3123 and a locking piece 3124. The bases 3121 on the multiple inspection fixtures 31 are respectively fixed on the workbench 1 and the side positioning frame 21 by screws. A groove 3122 is provided on the side of the base 3121 away from the threshold beam 4. Both ends of the groove 3122 pass through the base 3121. One end of the movable rod 3123 rotates on the inner wall of the groove 3122. At the same time, the design of the groove 3122 allows the movable rod 3123 to fit on the base 3121, so that the base 3121 can limit the movement of the movable rod 3123 to facilitate detection. The other end of the movable rod 3123 is fixed to the detection plate 311 by a screw, and the detection plate 311 is rotatable on the base 3121 through the movable rod 3123. When the movable rod 3123 rotates toward the side of the door sill beam 4 to abut against the bottom wall of the groove 3122, the detection plate 311 is in the detection state, and the locking member 3124 is used to lock the state when the movable rod 3123 rotates to abut against the bottom wall of the groove 3122. A handle 320 is also fixed to the part of the movable rod 3123 near the detection plate 311, and the handle 320 is used to facilitate the operator to rotate the movable rod 3123.

[0046] Reference Figure 1-Figure 7The locking member 3124 is a knob 3125 and a screw rod 3126. One end of the screw rod 3126 is fixedly connected to the knob 3125, and the other end is used to pass through the movable rod 3123 and then be threadedly connected to the base 3121. The operator can fix the movable rod 3123 to the base 3121 through the knob 3125 and the screw rod 3126, avoiding the need for manual fixation of the movable rod 3123 during the detection process.

[0047] Reference Figure 1-Figure 7 The base 3121 is provided with a rotation limit plate 3127, which is located on the rotation path of the movable rod 3123. When the movable rod 3123 rotates toward the side away from the threshold beam 4 until it abuts against the rotation limit plate 3127, the movable rod 3123 is away from the disassembly path of the threshold beam 4, and a distance is left between the movable rod 3123 and the workbench 1. The setting of the rotation limit plate 3127 prevents the movable rod 3123 from excessively rotating in the direction away from the threshold beam 4, and reduces the workload of the operator to move the movable rod 3123 to the detection state. It also prevents the movable rod 3123 from directly hitting the workbench 1 under the action of gravity, causing damage to the workpiece. The workbench 1 is also provided with a plurality of placement tables 11, and a socket for inserting the screw 3126 is opened on the top surface of the placement table 11. It is convenient for the operator to store the twisted knob 3125 on the workbench 1, reducing the situation where the knob 3125 is randomly placed and lost.

[0048] Reference Figure 1-Figure 7 The inspection fixture 31 also includes a pressing plate 314, and one end of the measuring needle 313 away from the threshold beam 4 is fixed on the pressing plate 314. A spring 315 is sleeved on the measuring needle 313, and the two ends of the spring 315 are respectively abutted on the pressing plate 314 and the detection plate 311. When there is no external force, the measuring needle 313 is located on the outside of the threshold beam 4. The operator can push the pressing plate 314 to move the measuring needle 313 toward the corresponding riveting hole 421 to be inspected, and when not inspecting, the measuring needle 313 will be reset under the action of the spring 315, and then the measuring needle 313 will be fixed above the detection plate 311, without the need for the operator to move the measuring needles 313 back and forth between the storage place and the detection plate 311 one by one each time for inspection.

[0049] Reference Figure 1-Figure 7The inspection fixture 31 also includes a positioning column 316, a detection light 317 and a push switch 318. The positioning column 316 is fixed on the detection plate 311, and the positioning column 316 is located between the detection plate 311 and the pressure plate 314. The detection light 317 is fixed on the side of the positioning column 316. The detection light 317 switch is a button type. The push switch 318 is fixed on the top surface of the positioning column 316 near one end of the pressure plate 314. The push switch 318 is used to control the detection light 317. When the pressure plate 314 presses on the push switch 318, the measuring needle 313 is fully inserted into the corresponding riveting hole 421. When the push switch 318 is pressed by the pressure plate 314, the detection light 317 lights up, and the operator can directly confirm whether the measuring pin 313 is inserted into the rivet hole 421 by the on and off of the detection light 317, thereby knowing whether the rivet hole 421 is standard, avoiding the situation where the operator needs to observe with the naked eye whether the measuring pin 313 is inserted into the rivet hole 421.

[0050] Reference Figure 1-Figure 7 A pull rod 319 is fixed on the side of the pressing plate 314 away from the threshold beam 4. The pull rod 319 is coaxial with the pressing plate 314 and is used to assist the operator in moving the pressing plate 314. The operator can move the pressing plate 314 in the direction of the detection plate 311 through the pull rod 319, so that the pressing plate 314 can be directly pulled down by standing at the side, thereby avoiding the operator having to push the pressing plate 314 from above, which is more laborious.
