Description

Technical Field

[0001] The utility model relates to the technical field of automobile stamping parts, in particular to a leak-proof processing hole detection tool. Background Art

[0002] To ensure the strength of the vehicle body, hot-formed steel is widely used in the automotive field. It is often used to strengthen the strength of other parts such as A-pillars, B-pillars, and central channels. Its tensile yield strength can reach more than 1000Mpa. High strength and toughness are typical characteristics of hot-formed parts, which can effectively ensure the safety of passengers. During the forming of hot-formed parts, in order to ensure product quality, process supplements will be added. Conventional contact processing has low efficiency and high loss, so laser cutting is used to cut holes and edges.

[0003] At present, the common quality problem in the laser cutting industry is missing holes, that is, the product holes are not cut, which affects the customer's assembly at the client end. The equipment end uses hole detection after cutting to achieve missing hole detection, but the false alarm rate of circular holes with a diameter of less than 10mm is high, causing downtime, and the detection time will affect the processing cycle, with low reliability and low economy. It cannot effectively prevent hole missing processing. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a leak-proof processing hole detection tooling, which solves the common quality problem in the current laser cutting industry of missed holes, that is, the product holes are not cut, which affects the customer's assembly at the client end. The equipment end adopts hole detection after cutting to achieve leak hole detection, but the false alarm rate of circular holes with a diameter of less than 10 mm is high, resulting in downtime, and the detection time will affect the processing rhythm, low reliability, and low economy.

[0005] To achieve the above purpose, the utility model is implemented through the following technical scheme: it includes an aluminum profile bracket, a detection pin mounting block is installed on the aluminum profile bracket, a fixed steel sleeve is installed on the detection pin mounting block, a hole detection pin is installed on the fixed steel sleeve, and a displacement sensor is installed on the aluminum profile bracket.

[0006] Preferably, coarse limit guides are installed on the aluminum profile bracket near both ends.

[0007] Preferably, a pair of positioning references are installed on the aluminum profile bracket.

[0008] Preferably, a side pull handle is installed on the aluminum profile bracket.

[0009] The utility model provides a leak-proof processing hole detection tool. It has the following beneficial effects: 40*40 aluminum profiles are used as the tool base, and fixed L blocks are processed according to different parts hole positions to fix the detection pins. The detection pins are fixed on the fixed L blocks through fixed steel sleeves. After cutting, the parts are placed on this tool to observe whether the parts are put into the tool to determine whether the parts have leaks. The side holes are pulled sideways, and the side pull passability is determined to determine whether there are leaks. A displacement sensor is added below the part where the side is pulled into place. When the part is put into the tool and the side is pulled into place, the sensor will have a signal. The sensor and the equipment are linked. The equipment can only perform the next cycle cutting after there are signals, avoiding workers' misoperation. During the use of the leak detection tool, another turntable of the equipment is used to cut parts, which will not increase the part processing beat.

[0010] To avoid manual observation errors, two displacement sensors are added in the vertical direction after the part is fully placed into the tooling, and one displacement sensor is added for one-way side pulling. The displacement sensor is linked to the equipment. If there is no signal from the displacement sensor, the equipment will not cut the next part to ensure that the part is placed in place and pulled sideways. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-3The utility model provides a technical solution: a leak-proof processing hole detection tooling, including an aluminum profile bracket 1, a detection pin mounting block 2 is installed on the aluminum profile bracket 1, a fixed steel sleeve 3 is installed on the detection pin mounting block 2, a hole detection pin 4 is installed on the fixed steel sleeve 3, and a displacement sensor 6 is installed on the aluminum profile bracket 1.

[0017] As a preferred technical solution, further, a coarse limit guide 8 is installed on the aluminum profile bracket 1 and near both ends.

[0018] As a preferred technical solution, further, a pair of positioning references 7 are installed on the aluminum profile bracket 1.

[0019] As a preferred technical solution, further, a side pull handle 5 is installed on the aluminum profile bracket 1.

[0020] It should be noted that: as shown in Figure 1, the hole detection pin 4 is installed on the fixed steel sleeve 3, the fixed steel sleeve 3 is installed on the detection pin mounting block 2, and the detection pin mounting block 2 is fixed to the aluminum profile bracket 1 by bolts. The part is smoothly placed on the tooling through the coarse limit guide 8, the part position is located by the positioning reference 7, and the side pull handle 5 is pulled. All hole detection pins 4 can pass through the part, and the displacement sensors 6 are all effective, which can confirm that the part has no leaking holes and proceed to the next cutting.

[0021] It should be noted that:

[0022] 1. The anti-leakage cutting hole tooling adds a displacement sensor 6 to work in conjunction with the equipment. If the leak hole of the part is not in place, the displacement sensor 6 has no signal and the equipment does not perform the next cutting.

[0023] 2. The hole detection pin 4 is fixed to the fixed steel sleeve 3 by a top screw, and the fixed steel sleeve 3 is fixed to the detection pin mounting block 2 by a top screw, ensuring that the hole detection pin 4 is easy to disassemble and not easy to fall off.

[0024] 3. The hole of the part passes through the perforation detection pin 4. The part has missed a hole, that is, the part is not placed properly on the leak-proof cut hole, which can determine your key leak.

[0025] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
