DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0030] See also Figure 1 , Figure 2 , Figure 5 and Figure 8 The present application provides an automobile motor housing inspection tool, comprising a base 1 and a top plate 2 and a support 3 located therebetween, and also comprising a motor housing bearing platform 4, a motor housing clamping member 5 and a motor housing water cooling channel port adjustable connecting member 6:

[0031] The motor housing carrying platform 4 is used to place the motor housing and is disposed on the base 1;

[0032] The motor housing pressing member 5 is disposed on the top plate 2 and is used to press the motor housing;

[0033] The adjustable connecting member 6 of the port of the water-cooling channel of the motor housing includes a fixed plate 61 arranged on one side of the base 1, a cylinder A62 is arranged on the fixed plate 61, a rectangular frame 64 is arranged at the end of the cylinder A62, mounting plates 65 are slidably connected in pairs in the rectangular frame 64, and a limiting member 68 for limiting the mounting plate 65 is also provided on the rectangular frame 64, and a plugging head 66 and an air intake pipe 67 corresponding to the two ports of the water-cooling channel of the motor housing are respectively provided on the two rectangular frames 64.

[0034] In this embodiment, the motor housing is clamped and fixed by using the motor housing support platform 4 and the motor housing clamping member 5. Figure 8 The positions of the inlet b and outlet a of the water-cooling channel of the motor casing are shown, and the position of the mounting plate 65 is readjusted by using the limit piece 68, so that the plugging head 66 and the air inlet pipe 67 can be respectively aligned with the inlet b and outlet a of the water-cooling channel of the motor casing, and the cylinder A62 is used to push the rectangular frame 64 forward, so that the plugging head 66 and the air inlet pipe 67 are respectively inserted into the inlet b and outlet a of the water-cooling channel of the motor casing, and the air inlet pipe 67 is connected to an external air pump, and the external air pump inflates the inlet b of the water-cooling channel on the side wall of the motor casing through the air inlet pipe 67, and then the air inlet pipe 67 is connected through an external air pressure testing instrument, and the air pressure in the water-cooling channel on the side wall of the motor casing is detected by the air pressure testing instrument. If there is a leak, the air pressure will be lower than the target value, so as to detect the air tightness of the water-cooling channel on the side wall of the motor casing.

[0035] It should also be noted that a rubber ring (not shown) that is movable and tightly attached to the inlet b and outlet a is adhered to the outer wall of the end of the sealing head 66 and the air inlet pipe 67 inserted into the inlet b and outlet a, thereby increasing the accuracy of the air tightness detection of the water cooling channel of the motor housing.

[0036] See also Figure 1 There are four pillars 3, and the two ends are respectively connected to the four corners of the opposite sides of the base 1 and the top plate 2. Specifically, the base 1 and the top plate 2 can be connected by the pillars 3, so that the motor housing can be placed between them.

[0037] See also Figure 1-Figure 3 The motor housing support platform 4 includes a turntable 41 located on the upper surface of the base 1, a screw 42 is fixedly connected to the axis of the turntable 41, and a through hole matching the screw 42 is opened at the center of the base 1, and a nut A43 is screwed on the screw 42 and pressed against the lower surface of the base 1. Specifically, when the position of the motor housing is deviated after clamping, that is, the axis of the water cooling channel inlet b and outlet a on the side of the motor housing is not in the same longitudinal plane as the axis of the plugging head 66 and the air inlet pipe 67, the nut A43 can be loosened at this time, and the position of the motor housing can be adjusted by rotating the turntable 41.

Specifically, a bearing is embedded in the insert 52, and the piston end of the cylinder B51 is connected to the inner wall of the bearing. Therefore, when the insert 52 is pressed against the front end of the motor housing, the cooperation between the insert 52 and the bearing can also assist the rotation of the turntable 41 to adjust the position of the water cooling channel inlet b and outlet a on the side of the motor housing.

[0039] See also Figure 5 The piston end of the cylinder A62 is connected with a U-shaped connecting rod 63, and the two ends of the U-shaped connecting rod 63 are respectively connected to the upper and lower ends of the middle part of the side of the rectangular frame 64. Specifically, the design of the U-shaped connecting rod 63 can make the cylinder A62 push the rectangular frame 64 more stably.

[0040] See also Figure 5 and Figure 6 The inner walls of the rectangular frame 64 are provided with slide rails A641 that match the mounting plate 65, and the outer walls of the rectangular frame 64 are provided with slide rails B642 that are connected to the corresponding slide rails A641 and are smaller in width than the slide rails A641. Specifically, the design of the slide rails A641 allows the mounting plate 65 to slide on the rectangular frame 64, and the design of the slide rails A641 facilitates the fixing and position adjustment of the stopper 68.

[0041] See also Figure 5 and Figure 7The stopper 68 includes a locking bolt 681 that can pass through the slide rail B642 and whose head is located in the slide rail A641. The outer wall of the locking bolt 681 is connected to a nut B682 that is pressed against the outer wall of the rectangular frame 64. There are eight stoppers 68, and the eight stoppers 68 are respectively pressed against the four corners of the two mounting plates 65. Specifically, the locking bolt 681 is passed through the slide rail B642 from the inner wall of the rectangular frame 64 so that its tail is exposed outside the rectangular frame 64, and then the nut B682 is tightened to fit the outer wall of the rectangular frame 64. After the installation is completed, it can be installed as shown in FIG. Figure 5 As shown, a limit is formed for the two mounting plates 65.

[0042] The four corners of the bottom of the base 1 are connected with supporting feet.

[0043] When using this application:

[0044] Place the motor housing on the upper surface of the turntable 41, with the rear end of the motor housing attached to the turntable 41, and start the cylinder B51 to drive the insert 52 to press down. At this time, the motor housing is clamped and fixed between the turntable 41 and the insert 52. Figure 8 The positions of the inlet b and outlet a of the water-cooling channel of the motor housing are shown, and the position of the mounting plate 65 is readjusted by using the limit piece 68, so that the plugging head 66 and the air inlet pipe 67 can be respectively aligned with the inlet b and outlet a of the water-cooling channel of the motor housing, and the cylinder A62 is used to push the rectangular frame 64 forward so that the plugging head 66 and the air inlet pipe 67 are respectively inserted into the inlet b and outlet a of the water-cooling channel of the motor housing, and the air inlet pipe 67 is connected to an external air pump, and the external air pump inflates the inlet b of the water-cooling channel on the side wall of the motor housing through the air inlet pipe 67, and then the air inlet pipe 67 is connected through an external air pressure testing instrument, and the air pressure in the water-cooling channel on the side wall of the motor housing is detected by the air pressure testing instrument. If there is a leak, the air pressure will be lower than the target value, so as to detect the air tightness of the water-cooling channel on the side wall of the motor housing. The detection tooling of this application is suitable for Fig. 9 Connection detection of motor water cooling channel ports at different distances as shown in the figure.

[0045] In addition, it should be noted that in the present application, when the water cooling channel port is located at one end of the motor housing, the motor housing in the present application is placed and clamped horizontally, and then the positions of the plugging head 66 and the air intake pipe 67 are adjusted so that the two openings at the end are connected with the plugging head 66 and the air intake pipe 67 respectively, so that air tightness testing can also be performed.
