[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 4 The present invention provides an embodiment of a turbocharger displacement detection device, comprising an exhaust gas intake simulation mechanism, an internal combustion engine cylinder simulation mechanism, an adjustment switch, and a base plate 1. A turbocharger mounting base 2 is fixedly connected to the base plate 1. The turbocharger mounting base 2 includes support legs and a support plate fixedly mounted on the support legs. The turbocharger mounting base 2 is used to provide support for a turbocharger body 3. The turbocharger mounting base 2 is provided with a clamping assembly 4 for clamping the turbocharger body 3 and a fixing assembly 5 for fixing a connecting flange of the turbocharger body 3.

[0024] refer to Figure 1The exhaust gas intake simulation mechanism is used to simulate the exhaust gas entering the turbocharger body 3, the internal combustion engine cylinder simulation mechanism is used to simulate the operation of the internal combustion engine cylinder, the adjustment switch is used to adjust the airflow, and it is also coordinated with the barometer, flow meter, and display. The specific working principle can be referred to the existing technology, and this part will not be repeated.

[0025] There are three clamping assemblies 4, which are evenly arranged around the circumference. The clamping assembly 4 includes a mounting plate 401 fixedly mounted on the turbocharger mounting base 2. A clamping cylinder 402 is fixedly mounted on the mounting plate 401. The output end of the clamping cylinder 402 is fixedly connected to a drive base 403. A lower elastic body 404 and an upper elastic body 405 are fixedly connected to the drive base 403. The cross-sections of the upper elastic body 405 and the lower elastic body 404 are both circular. The upper elastic body 405 is located above the lower elastic body 404. The upper elastic body 405 and the lower elastic body 404 are each grouped in pairs.

[0026] refer to Figure 4 、 Figure 2 During the clamping operation, the turbocharger body 3 is placed on the turbocharger mounting seat 2. Under the action of the external air source, the clamping cylinder 402 drives the driving seat 403, the upper elastic body 405, and the lower elastic body 404 to move, so that the upper elastic body 405, the lower elastic body 404 and the outer surface of the turbocharger body 3 are in contact with each other. Since the upper elastic body 405 and the lower elastic body 404 are elastic, the clamping force is too large to cause damage to the turbocharger body 3. There is no need to use bolts for fixing, which saves the time for fixing the turbocharger body 3 and improves the efficiency of detection.

[0027] There are two fixing components 5, which are evenly arranged around the circumference. The fixing component 5 includes a fixing plate 502, on which a fixing cylinder 501 is fixedly mounted. The output end of the fixing cylinder 501 is fixedly connected to a fixing claw 503, and the cross-sectional shape of the fixing claw 503 is a semicircular ring. A receiving groove 504 is provided in the fixing claw 503, and a sealing gasket is fixedly connected to the inner wall of the receiving groove 504.

[0028] refer to Figure 4 、 Figure 2 When the flange is fixed, the external connecting flange is aligned with the connecting flange of the turbocharger body 3. A sealing gasket can be added between the two connecting flanges. Then, the fixing cylinder 501 drives the fixing claws 503 close to the connecting flange under the action of the external air source. The two fixing claws 503 can be used to fix the two connecting flanges, thereby saving the connection time of bolts and nuts and improving the connection efficiency.

[0029] During use, during the clamping operation, the turbocharger body 3 is placed on the turbocharger mounting seat 2, and the clamping cylinder 402 drives the driving seat 403, the upper elastic body 405, and the lower elastic body 404 to move under the action of the external air source, so that the upper elastic body 405, the lower elastic body 404 and the outer surface of the turbocharger body 3 are in contact with each other. Since the upper elastic body 405 and the lower elastic body 404 are elastic, it is possible to avoid excessive clamping force, which may cause damage to the turbocharger body 3. No bolts are required for fixing, which saves time for fixing the turbocharger body 3 and improves the efficiency of detection. When fixing the flange, the external connecting flange and the connecting flange of the turbocharger body 3 are matched with each other, and a sealing gasket can be added between the two connecting flanges. Then, the fixing cylinder 501 drives the fixing claw 503 under the action of the external air source to approach the connecting flange. The two fixing claws 503 can be used to fix the two connecting flanges, thereby saving the connection time of bolts and nuts and improving the efficiency of connection. The provided clamping assembly 4 can automatically provide multiple clamping forces to the turbocharger body 3, thereby eliminating the need for bolts for fixing, saving time for fixing the turbocharger body 3 and improving detection efficiency; the provided fixing assembly 5 can provide fixing force to the connecting flange of the turbocharger body 3, improving the efficiency of installation operations at the connecting flange and making it easy to use.

[0030] Working principle: When in use, during the clamping operation, the turbocharger body 3 is placed on the turbocharger mounting seat 2, and the clamping cylinder 402 drives the driving seat 403, the upper elastic body 405, and the lower elastic body 404 to move under the action of the external air source, so that the upper elastic body 405, the lower elastic body 404 and the outer surface of the turbocharger body 3 are in contact with each other. Since the upper elastic body 405 and the lower elastic body 404 are elastic, it is possible to avoid excessive clamping force, which may cause damage to the turbocharger body 3. No bolts are required for fixing, which saves time for fixing the turbocharger body 3 and improves the efficiency of detection. When fixing the flange, the external connecting flange and the connecting flange of the turbocharger body 3 are matched with each other, and a sealing gasket can be added between the two connecting flanges. Then, the fixing cylinder 501 drives the fixing claw 503 under the action of the external air source to approach the connecting flange. The two fixing claws 503 can be used to fix the two connecting flanges, thereby saving the connection time of bolts and nuts and improving the efficiency of connection.
