A quality inspection tool for automotive sheet metal parts

Abstract

This utility model discloses a quality inspection tool for automotive sheet metal parts, including a fixed platform, inspection pins, a positioning plate fixedly connected to the fixed platform, and a pressure plate clamp fixedly installed. The positioning plate movably engages the sheet metal part through an inspection positioning groove on its side and is fixed by the pressure plate clamp. Standard inspection holes are provided on the positioning plate at positions corresponding to the mounting holes on the sheet metal part. A translation bracket is slidably connected to the upper surface of the fixed platform on the side of the positioning plate away from the pressure plate clamp. This utility model, by setting inspection positioning grooves on the positioning plate, first inspects the overall outline shape of the sheet metal part through the inspection positioning grooves. If the parts fit perfectly, the overall outline is qualified. A translation bracket drives multiple inspection pins to be inserted into the mounting holes simultaneously. The qualification of the mounting holes is determined based on the insertion of the inspection pins. All parallel mounting holes on the sheet metal part can be inspected at once without inserting and removing the inspection pins one by one, greatly improving efficiency.

Description

Technical Field

[0001] This utility model relates to the field of quality inspection tools, specifically a quality inspection tool for automotive sheet metal parts. Background Technology

[0002] There are numerous sheet metal parts in the car body and chassis structure. During the production process, they need to be inspected to monitor production quality and ensure product quality. Among them, the inspection tool for inserting and removing pins is particularly suitable for the positioning and inspection of mounting holes on small sheet metal parts.

[0003] Before testing, the sheet metal parts are pressed and fixed to one side of the positioning plate using a clamping plate. From the other side, the test pins are manually inserted one by one. If the test pin passes through the standard test hole on the positioning plate and can smoothly pass through the mounting hole on the sheet metal part, it indicates that the mounting hole is qualified. If the test pin can only be partially inserted into the mounting hole on the sheet metal part, it indicates that the mounting hole is not vertical and has a tilting error. If the test pin cannot be inserted into the mounting hole on the sheet metal part at all, it indicates that the mounting hole is completely offset.

[0004] Although this inspection tool is simple to use, inserting and removing the inspection pins one by one is still quite time-consuming. When there are a large number of sheet metal parts and mounting holes to inspect, the efficiency of the inspection is difficult to keep up and urgently needs to be improved. Utility Model Content

Detailed Description of the Embodiments

[0015] 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.

[0016] like Figure 1-4 As shown, this utility model provides a technical solution: a quality inspection tool for automotive sheet metal parts, including a fixed platform 1, an inspection pin 2, a positioning plate 3 fixedly connected to the fixed platform 1, and a pressure plate clamp 4 fixedly installed. The positioning plate 3 movably engages the sheet metal part 6 through the inspection positioning groove 5 provided on the side and is fixed by the pressure plate clamp 4. A standard inspection hole 8 is provided on the positioning plate 3 at the position corresponding to the mounting hole 7 on the sheet metal part 6. A translation bracket 9 is slidably connected to the upper surface of the fixed platform 1 on the side of the positioning plate 3 away from the pressure plate clamp 4. The upper surface of the fixed platform 1 is provided with symmetrical sliding grooves 15. A slider 16 is slidably connected in the sliding grooves 15 and fixedly connected to the bottom of the translation bracket 9. A detection push rod 17 connected to the side of the translation bracket 9 away from the positioning plate 3 is also installed on the fixed platform 1. A detection pin 2 is horizontally inserted at the position corresponding to the standard detection hole 8 on the translation bracket 9. A connecting rod 10 is fixed to one end of the detection pin 2 away from the positioning plate 3 and a relief spring 11 is sleeved on its surface. The two ends of the relief spring 11 are fixedly connected to the end of the detection pin 2 and the corresponding side wall of the translation bracket 9. The connecting rod 10 passes through the translation bracket 9 and the fixing frame 12 fixed to the side of the translation bracket 9. A vertically set detection flap 13 is movably hinged on the fixing frame 12. Horizontal detection grooves 14 are equidistantly set in the vertical direction on the side of the detection flap 13 away from the connecting rod 10. The connecting rod 10 contacts the detection flap 13. The detection flap 13 is movably hinged to the fixing frame 12 through an integral shaft near the top edge. The connecting rod 10 and the detection flap 13 are positioned at the lower side of the side. There are multiple mounting holes 7. The mounting holes 7, standard detection holes 8, detection pins 2, connecting rod 10, relief spring 11, fixing frame 12 and detection flap 13 correspond one-to-one.

[0017] Working principle: The sheet metal part 6 is installed into the detection positioning groove 5 on the side of the positioning plate 3. The overall outline shape of the sheet metal part 6 is inspected through the detection positioning groove 5. If the fit is correct, the overall outline is qualified. If it is not qualified, no further inspection is required. After confirming that the outline shape of the sheet metal part 6 is qualified, it is pressed by the pressure plate clamp 4. The translation bracket 9 is used to move along the slide groove 15 from right to left, driving multiple detection pins 2 to move to the left and insert into the mounting hole 7. If the mounting hole 7 is qualified, the detection pins 2 can be inserted smoothly without obstructing the detection pins 2, causing the relief spring 11 to contract and push the detection flip plate 13 to flip to the right. If the mounting hole 7 is not qualified, the detection pins 2 cannot be inserted smoothly. This will cause the detection pin 2 to push the relief spring 11 to the right, thereby pushing the detection flap 13 to flip to the right. The detection results can be obtained from multiple aspects such as the insertion of the detection pin 2, the contraction of the relief spring 11, and the flipping of the detection flap 13. The design of the detection groove 14 helps to observe the flipping of the detection flap 13 from a top view, making the visual effect more obvious. After the detection is completed, the translation bracket 9 is moved to the right. The relief springs 11 fixed at both ends can pull the detection pin 2 away from the mounting hole 7 at the same time. By performing quality inspection on all parallel mounting holes 7 on the sheet metal part 6 at one time, it is not necessary to insert and remove the detection pin 2 one by one, which can greatly improve the efficiency.
