[0002] The hydraulic torque converter is also called "hydraulic torque converter", "turbine torque converter" and "dynamic hydraulic torque converter". It is a type of hydraulic transmission component, consisting of a pump wheel, a turbine and a guide wheel. The pump wheel is connected to the driving shaft, and can convert the mechanical energy input by the driving shaft into the kinetic energy and pressure head of the liquid by relying on the action of centrifugal force, so that the turbine can do work. The turbine is connected to the driven shaft, and the kinetic energy of the liquid and the energy contained in the pressure head can be output by the driven shaft. The hydraulic torque converter is also called "hydraulic torque converter", "turbine torque converter" and "dynamic hydraulic torque converter", and consists of a pump wheel, a turbine and a guide wheel.

[0003] Once a torque converter fails, it is usually due to a problem with the sealed internal structure. If repairs are required, the torque converter needs to be completely cut open, and then the damaged parts need to be identified and replaced. After the replacement is completed, the original cut part needs to be welded. A series of tests need to be performed on the torque converter before and after welding to reduce the probability of other problems after welding. The conventional method requires the torque converter to be placed in different tools for inspection, welding, and then inspection, which is very inconvenient. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the utility model provides a rapid detection device for a hydraulic torque converter, which solves the technical problem of the inconvenience of the process of welding and reciprocating transportation of the hydraulic torque converter after repair.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

[0008] An embodiment of the utility model provides a rapid detection device for a torque converter, comprising a detection platform, a coaxiality detection component, a pressure detection component, a flatness detection component and a welding component arranged on the upper end of the detection platform, wherein the coaxiality detection component comprises a rotating support platform vertically rotatably connected to the upper end surface of the detection platform and for placing the torque converter, a retaining slide vertically slidably arranged on the upper side of the rotating support platform, and a rotating head rotatably arranged at the lower end of the retaining slide and fixing the top of the torque converter, wherein the rotating support platform, the torque converter and the rotating head are arranged vertically coaxially.

[0009] The utility model embodiment proposes a rapid detection device for a torque converter. When the torque converter is repaired, the torque converter is assembled and placed on the upper end of a rotating support platform, so that the rotating support platform, the torque converter and the rotating head are vertically coaxial. Then the holding slide is moved vertically downward to move the rotating head to be fixed with the top of the torque converter. Then the rotating support platform is rotated to determine the rotation posture of the torque converter, thereby detecting the coaxiality of the upper and lower parts of the torque converter. Then the flatness detection component is used to detect the flatness of the part of the top of the torque converter connected to the driving shaft. Then the upper and lower parts of the torque converter are welded by the welding component. After the welding is completed, the internal part of the torque converter is pressure tested by the pressure detection component to determine the sealing effect of the welding. This scheme reduces the number of reciprocating transportation in the process of detecting welding and then detecting the torque converter after repair, and is more convenient.

[0010] Optionally, the pressure detection assembly includes an air pump arranged at the side end of the detection platform, an air pump connected to the air outlet end of the air pump, and an air pressure detection gauge arranged on the air pump pipe, and the air outlet end seal of the air pump pipe is detachably connected to the torque converter.

[0011] By connecting the air outlet of the air pump with the top of the torque converter, and then using an air pump to pump air into the torque converter and pressurize it, when the pressure reaches a certain value, the change in the air pressure detection indication is observed within a certain period of time, so as to determine the firmness and sealing of the welding part of the torque converter. This solution makes pressure detection more convenient.

[0012] Optionally, the pressure detection assembly also includes a water tank vertically slidably disposed on the upper end of the detection platform and located on one side of the rotating support platform, and a positioning frame horizontally disposed on the upper end of the detection platform and immersed in the water tank as it moves vertically upward.

[0013] By setting up a positioning frame and a water tank, when the torque converter is welded, the torque converter can be directly placed on the positioning frame, and then the air pipe is connected to the top of the torque converter, and the water tank is moved vertically upward to immerse the torque converter in the water tank. At this time, after the torque converter is inflated and pressurized, the welding sealing effect can be determined by observing whether bubbles are generated at the welding point of the torque converter in the water tank. In combination with an air pressure detection gauge, the detection of the welding part of the torque converter is more accurate and faster.

[0014] Optionally, a movable slide is vertically slidably provided at the upper end of the detection platform, the air outlet end of the air pumping pipe is vertically fixed to the movable slide, and the movable slide moves vertically downward and drives the air outlet end of the air pumping pipe to clamp the torque converter on the positioning frame.

[0015] By vertically sliding a movable slide on the upper end of the detection platform, the end of the air pumping pipe is connected to the movable slide, so that the torque converter is clamped and fixed by the movable air pumping pipe and the positioning frame, so that the clamped torque converter can be completely immersed in the water tank, and at the same time the air outlet end of the air pumping pipe and the torque converter are fixed more firmly.

[0016] Optionally, an ultrasonic vibrator is arranged inside the water tank.

[0017] By arranging an ultrasonic vibrator inside the water tank, when the torque converter is repaired, the parts inside the torque converter can be placed in the water tank and cleaned by ultrasonic vibration. At the same time, the torque converter can also be ultrasonically cleaned after the inspection is completed, which is more convenient.

[0018] Optionally, the flatness detection assembly includes an adjustment frame rotatably connected to the side end of the retaining slide, a flatness probe horizontally arranged at one end of the adjustment frame away from its own rotation axis, and a runout meter arranged at the side end of the flatness probe, and the flatness probe rotates with the adjustment frame and abuts against the side end of one end of the torque converter connected to the driving shaft.

[0019] After the torque converter is installed on the rotating support platform, the flatness probe can be made to abut the side end of one end of the torque converter connected to the driving shaft by rotating the adjustment frame. At this time, the rotating support platform rotates, and the flatness probe will continue to abut the torque converter. At this time, the flatness of one end of the torque converter connected to the driving shaft can be detected by observing the changes in the pointer on the runout instrument.

[0020] Optionally, the welding assembly includes a welding bracket rotatably connected to the upper end of the detection platform and a welding head arranged at one end of the welding bracket away from its own rotation axis, and the welding head rotates with the welding bracket and abuts against the side end of the torque converter.

[0021] By rotating the welding bracket, the welding head can be brought into contact with the side end of the torque converter. At this time, the torque converter can be rotated while welding is performed, making the welding more uniform, more convenient and faster.

[0022] Optionally, a supporting shaft is vertically arranged in the middle of the upper end surface of the rotating supporting platform, and sliding grooves are evenly spaced circumferentially around the supporting shaft on the upper end surface of the rotating supporting platform, and a rubber support block supported on the outer edge of the lower end of the torque converter is slidably arranged in the sliding groove, and a support groove for the lower edge of the torque converter to be embedded is provided on one side of the rubber support block close to the torque converter.

[0023] By slidingly arranging a rubber support block on the end surface of the rotating support platform, on the one hand, the hydraulic torque converter can be supported to make the hydraulic torque converter more stable, and on the other hand, the hydraulic torque converter will not be scratched, which is safer.

[0024] Optionally, a tension spring is provided in the slide groove at one end close to the supporting shaft, and one end of the tension spring is fixed to a side end of the rubber supporting block and pulls the rubber supporting block to move toward one side of the supporting shaft.

[0025] By arranging a tension spring in the slide groove, the rubber support block can move toward the side of the supporting shaft under the pull of the tension spring, so that when the torque converter is installed on the rotating support platform, it is only necessary to move the rubber support block to the side away from the supporting shaft. After the torque converter is installed, the rubber support block is released and the rubber support block moves along the slide groove and is partially supported on the outer side of the lower end of the torque converter, which is more convenient.

After the torque converter is assembled, place it on the upper end of the rotating support 21 so that the rotating support 21, the torque converter and the rotating head 23 are vertically coaxial. Then, move the holding slide 22 vertically downward so that the rotating head 23 moves to be fixed on the top of the torque converter. Then, rotate the rotating support 21 to determine the rotation posture of the torque converter, thereby detecting the coaxiality of the upper and lower parts of the torque converter.
