[0002] At present, there is a laser transmission welding process in the assembly process of the steering gear electronic control unit. The laser emitted by the laser generator of this process penetrates the plastic shell and acts on the surrounding of the shell to melt it due to heat. Since the plastic shell and the shell are in an interference fit relationship, the surrounding of the shell can be melted to achieve a close connection with the plastic shell, and finally the product welding is realized.
[0003] According to statistics, the scrap rate of laser transmission welding process is the highest in the assembly process of steering gear electronic control unit, and the high scrap rate also leads to increased costs.
[0004] The main reason for the failure of laser transmission welding is that the transmittance of the plastic shell is unstable, which causes the laser to be unable to penetrate the plastic shell well, resulting in low energy acting around the shell, and ultimately causing the welding effect to fail to meet quality requirements.
[0005] Therefore, it is necessary to design a fixed fixture for detecting the light transmittance of a plastic shell to measure the plastic shell stably, quickly and at a uniform angle, so as to facilitate the rapid verification of the light transmittance performance of the plastic shell.

[0024] The utility model is now further described with reference to the accompanying drawings.
[0025] See also Figure 1 The utility model is a fixed tool for detecting the light transmittance of a plastic shell, comprising a bottom plate, a light transmittance detection device, a guide rail, a slider, a locking mechanism, a sleeve mounting seat, and a sleeve. A light transmittance detection device 5 is installed on one side of the top of the bottom plate 7, and a guide rail 10 is installed on the other side of the top of the bottom plate 7.

The slider 4 slides back and forth and is quickly locked, which is convenient for the installation and removal of the plastic shell 2. A sleeve mounting seat 15 is installed on the top of the slider 4, and a rotatable sleeve 3 is installed on the vertical surface of the sleeve mounting seat 15. The plastic shell 2 is installed on one end of the sleeve 3 close to the light transmittance detection device 5. The outer surface of the sleeve 3 is provided with a scale 31, and the interval between each two adjacent scale lines of the scale 31 is 5°, which is convenient for the measurement personnel to evenly measure the light transmittance of the plastic shell 2. A top screw 32 is installed on the wall of the sleeve 3, and the end of the top screw 32 abuts against the outer surface of the plastic shell 2 to ensure that the sleeve 3 and the plastic shell 2 are accurately matched. The edge of the plastic shell 2 is exposed outside the sleeve 3 , and the edge of the plastic shell 2 is located between the detection probe and the light source of the light transmittance detection device 5 .
[0026] See also Figure 2 The transmittance detection device 5 is installed on the bottom plate 7 by using a locking mechanism 1 to achieve locking and fixing of the transmittance detection device 5.

The middle part of the connector 13 is connected to the support seat 12. The handle 11 is provided at one end of the connector 13, and a rubber head 14 is provided at the bottom of the other end of the connector 13. The rubber head 14 is against the transmittance detection device 5. The rubber head 14 can avoid damage to the transmittance detection device 5 caused by excessive clamping force, and at the same time can increase friction and improve the fixing effect of the transmittance detection device 5.

[0028] The side of the stop block 9 is an inclined structure, and the top plane of the stop block 9 is provided with a center hole matching the end of the spring buckle 8. When the slider 4 moves forward and backward, when the spring buckle 8 contacts the inclined structure of the stop block 9, the spring buckle 8 will automatically retract, and when the end of the spring buckle 8 contacts the center hole of the stop block 9, the spring buckle 8 extends and inserts into the center hole of the stop block 9, and the position of the slider 4 is fixed, ensuring that the position of the plastic housing 2 is stable during measurement or installation and disassembly.
[0029] See also Figure 4 , Figure 5 A bearing 16 is provided between the sleeve mounting seat 15 and the sleeve 3 to facilitate free rotation of the sleeve 3 in the circumferential direction.
[0030] A handle 6 is installed on the side of the slider 4 to facilitate the measurement personnel to move the slider 4 to install or remove the plastic housing 2.
[0031] See also Figure 6 , Figure 7 A cylinder 33 is installed in the sleeve 3, and the setting position of the cylinder 33 matches the pressing area 21 of the plastic shell 2 to avoid damage to the plastic shell 2.
[0032] There are three top screws 32 , and the interval between every two adjacent top screws 32 is 120°, so that the top screws 32 can better lock the plastic housing 2 to be measured.
[0033] When the utility model is in operation, the plastic shell 2 is firmly installed in the sleeve 3, the position of the slider 4 on the guide rail 10 is adjusted, and after the spring buckle 8 is locked with the stop block 9 at the test position, the transmittance detection device 5 is turned on, and the sleeve 3 is driven to rotate manually or by a motor, and the transmittance detection device 5 detects the exposed edge of the plastic shell 2, and the measurement personnel evenly measure and regularly record the measurement data according to the scale 31.
