[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1-7 As shown, a testing fixture for a four-corner connector 31 includes a testing platform 1. An upper positioning component and a lower positioning component are provided on the upper left side of the testing platform 1, respectively positioning the two ends of the four-corner connector 31. A quick clamp 34 is installed at the middle position of the upper part of the testing platform 1. After positioning, the quick clamp 34 is used to clamp and fix the four-corner connector 31 against its end face. A vertical plate 13 is installed on the upper right side of the testing platform 1. The vertical plate 13 is set vertically, and several test pins 14 are inserted inside the vertical plate 13. The end of the test pins 14 facing the four corner connecting frame 31 is connected to the test pins 2 15. The diameter of the test pins 2 15 is smaller than that of the test pins 14. The end of the test pins 2 15 facing the four corner connecting frame 31 can be threaded to the equal height screws 16. The outer periphery of the test pins 14 and 2 15 is respectively provided with test grooves 17 and 2 18. After the four corner connecting frame 31 is fixed, the end face to be tested of the hole seat 32 is parallel to the end face of the vertical plate 13 on the side away from the four corner connecting frame 31.
[0024] Push the first detection pin 14 towards the four-corner connecting bracket 31. If the opening position of the hole seat 32 is accurate, the second detection pin 15 can be inserted into the hole of the hole seat 32; if the opening position of the hole seat 32 is inaccurate, the second detection pin 15 cannot be inserted. Wait until the end face of the second detection pin 14 abuts against the end face of the hole seat 32 to be tested, and observe the positional relationship between the end face of the vertical plate 13 and the first detection groove 17. If the end face of the vertical plate 13 is within the width range of the first detection groove 17, it indicates that the machining height of the hole seat 32 is correct. Based on the qualified inspection, screw the equalization screw 16 into the end of the second detection pin 15 and tighten it. Pull the first detection pin 14 away from the four-corner connecting bracket 31 until the head of the equalization screw 16 abuts against the stepped surface inside the hole seat 32. Determine whether it is qualified by observing the positional relationship between the second detection groove 18 and the end face of the hole seat 32. If the end face of the hole seat 32 is within the width range of the second inspection groove 18, it indicates that the machining depth of the inner step surface of the hole seat 32 is qualified; if the end face of the hole seat 32 is not within the width range of the second inspection groove 18, the machining of the inner step surface of the hole seat 32 is unqualified.
[0025] The quick clamp 34 includes a rubber head that abuts against the four corner connectors 31, preventing damage to the surface of the four corner connectors 31 during clamping.
[0026] like Figure 1 , Figure 2 As shown, the upper positioning component includes a rotating seat 7, on which a positioning plate 8 is rotatably mounted, and a positioning pin 9 passes through the positioning plate 8. By flipping the positioning plate 8 so that it reaches above the end of the four-corner connecting bracket 31, the positioning pin 9 is then inserted into the hole at that end to complete the positioning.
[0027] Positioning plate 2 8 includes a mounting block 10, and a detection plate 11 is inserted inside the mounting block 10. A detection step 12 is provided on the side of the detection plate 11. The detection step 12 is used to detect the processing status of the ends of the four corner connecting brackets 31. If the detection step 12 can abut against the ends of the four corner connecting brackets 31 during the descent of the detection plate 11, it indicates that the processing of that end is qualified; if the detection step 12 fails to abut against the ends of the four corner connecting brackets 31 and continues to descend during the descent of the detection plate 11, it indicates that the processing of that end is unqualified.
[0028] The lower positioning component includes a positioning ring 2, a positioning post 3, and a rotating seat 4. The positioning ring 2 and the positioning post 3 are set on the detection platform 1. The positioning post 3 is located inside the positioning ring 2. A positioning plate 5 is rotatably set on the upper part of the rotating seat 4. A positioning pin 6 passes through the positioning plate 5.
[0029] The end of the four-corner connecting bracket 31 is placed inside the positioning ring 2 and supported by the positioning pin 3. The positioning plate 5 is flipped over to the top of the end of the four-corner connecting bracket 31, and the positioning pin 6 is inserted into the hole at the end of the four-corner connecting bracket 31 to complete the positioning of the end.
[0030] The testing platform 1 is equipped with several positioning rods 35. The positioning rods 35 are inserted into the holes of the four corner connecting brackets 31 for auxiliary positioning and support. The top of the positioning rod 35 is hemispherical, which makes it easy for the end of the positioning rod 35 to be inserted into the hole.
[0031] A horizontal plate 36 is connected to the upper part of the vertical plate 13. The horizontal plate 36 is horizontally positioned, and a second positioning post 37 is installed on the horizontal plate 36. A third positioning pin 38 passes through the second positioning post 37. The lower end of the second positioning post 37 can be inserted into the groove on the upper part of the four-corner connecting bracket 31 for auxiliary positioning. Then, the third positioning pin 38 is inserted into the second positioning post 37, so that the lower end of the third positioning pin 38 can be inserted into the hole at the bottom of the groove to initiate further positioning.
[0032] The testing platform 1 is equipped with a mounting base 19, and a testing pin 20 is inserted inside the mounting base 19. The mounting base 19 is vertically set, and the axis of the testing pin 20 is perpendicular to the vertical direction. A testing pin 24 is inserted on the testing platform 1. A testing hole is opened on the testing pin 20 for the testing pin 24 to pass through, and a testing groove 23 is opened on the outer periphery of the testing pin 20.
[0033] Move the third detection pin 20 towards the four-corner connecting bracket 31 so that the end of the third detection pin 20 abuts against the side of the four-corner connecting bracket 31. Then move the fourth detection pin 24 upward so that the fourth detection pin 24 passes through the machining hole on the four-corner connecting bracket 31 and through the detection hole on the third detection pin 20. If the position of the fourth detection pin 24 corresponds to the third detection groove 23, it indicates that the relative position of the side wall of the four-corner connecting bracket 31 and the machining hole is qualified.
[0034] like Figure 6 As shown, a guide hole 22 is provided on the detection pin 3 20. The guide hole 22 is set through the detection pin 3 20. The length direction of the guide hole 22 is set along the radial direction of the detection pin 3 20. The through direction of the guide hole 22 is set along the radial direction of the detection pin 3 20. A guide rod 21 is provided on the mounting base 19. The guide rod 21 is set through the guide hole 22. The movement direction of the detection pin 3 20 is restricted by the cooperation of the guide rod 21 and the guide hole 22, so as to ensure that the detection pin 4 24 can accurately pass through the detection hole on the detection pin 3 20.
[0035] like Figure 7As shown, the testing platform 1 is equipped with a mounting base 25 and a support rod 30. The mounting base 25 has an oblong hole 26, and a testing pin 27 passes through the oblong hole 26. The outer periphery of the testing pin 27 is provided with a testing groove 28. The upper part of the testing pin 27 is provided with a horizontal testing surface, and the end face of the testing groove 28 is provided with a testing groove 29.
[0036] The support rod 30 supports the protrusions 33 on the four-corner connecting bracket 31. The detection pin 27 moves forward within the oblong hole 26, so that the end of the detection pin 27 abuts against the side of the protrusion 33. At this time, observe the positional relationship between the end face of the mounting base 25 and the detection groove 28. If the end face of the mounting base 25 is within the width range of the detection groove 28, then the side of the surface protrusion 33 is properly machined.
[0037] Next, move the detection pin 27 upward within the oblong hole 26 so that the detection surface on the detection pin 27 abuts against the step of the protrusion 33. Observe the detection groove 29 and the detection surface. If the detection surface is within the width range of the detection groove 29, it indicates that the step of the protrusion 33 is processed to be qualified.
[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
