Description

Technical Field

[0001] This utility model belongs to the technical field of hydraulic torque converter testing tooling, and relates to a device for detecting the axial movement of a hydraulic torque converter. Background Technology

[0002] Hydraulic torque converters, as key components of integrated transmission systems, are widely used in special vehicles. Currently, research on integrated transmission systems largely focuses on the machining accuracy of key components and the assembly process, while research on ensuring the inspection accuracy of key components during assembly is relatively limited. In particular, the traditional methods for detecting axial movement during the assembly process of key components are flawed, leading to low accuracy in inspecting assembly tolerances. This not only reduces the accuracy of judging the inspection results but also lowers the overall assembly quality of the integrated transmission system.

[0003] The existing method for detecting axial movement of the hydraulic torque converter, a key component of an integrated transmission system, is the support method. This involves the operator manually supporting the pump impeller housing with a copper rod, applying an upward supporting force to the entire hydraulic torque converter, and then measuring the axial movement of the guide wheel shaft's large end face under these conditions. Since the pump impeller and other key components of the integrated transmission are made of aluminum alloy, the support method not only significantly affects the strength of the internal cast aluminum parts but also the precision of critical components such as the housing and outer ring. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a hydraulic torque converter axial movement detection device, which includes: a top seat 1, support legs 2, and a base 3. The top seat 1 and the base 3 are supported and connected by a plurality of support legs 2. The top seat 1 has a circumferentially convex surface on its top and a concave surface in its middle. The convex surface and the concave surface are positioned in conjunction with the hydraulic torque converter to apply a downward force to the hydraulic torque converter and measure the axial movement of the hydraulic torque converter relative to the concave surface of the top seat 1.

[0008] The base 3 is an annular disc with a first positioning groove. The lower end of the support leg 2 is embedded in the first positioning groove of the base 3 and is welded together by an annular weld.

[0009] The top seat 1 is an annular disc with a second positioning groove at its bottom. The upper end of the support leg 2 is embedded in the second positioning groove of the top seat 1 and is welded together by an annular weld.

[0010] The top seat 1 has four arc-shaped bosses spaced at intervals on its top circumference to support the pump wheel housing plane of the hydraulic torque converter.

[0011] Among them, the concave surface between the four arc-shaped bosses and the concave surface in the middle of the top seat 1 support the large end face of the guide wheel shaft of the hydraulic torque converter.

[0012] The top seat 1 is connected and fixed to the large end face of the hydraulic torque converter guide wheel shaft by bolts 4 and nuts 5 passing through the top seat 1.

[0013] Among them, there are 8 through holes distributed on the concave surface in the middle of the top seat 1. The large end face of the hydraulic torque converter guide wheel shaft is fixed by bolt 4 and nut 5 using the diagonal tightening method.

[0014] The diameter of the base 3 is larger than that of the top seat 1, and there are four legs 2, which are evenly distributed to connect the base 3 and the top seat 1.

[0015] During the axial movement detection, the base 3 is placed on a horizontally arranged work platform.

[0016] During the axial movement detection, the axial movement value is measured four times using a ruler from the concave surface between the four arc-shaped bosses of the top seat 1. The axial movement value is read from three different points at each concave surface.

[0026] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0027] Reference Figures 1 to 5 As shown, the hydraulic torque converter axial movement detection device in this embodiment includes a top seat 1, support legs 2, and a base 3. The top seat 1 and the base 3 are connected by several support legs 2. The top seat 1 has a circumferentially convex surface and a concave surface in the middle. The convex surface and the concave surface are positioned in conjunction with the hydraulic torque converter to apply a downward force to the hydraulic torque converter and measure the axial movement of the hydraulic torque converter relative to the concave surface of the top seat 1.

[0028] The base 3 is an annular disc with a first positioning groove. The lower end of the support leg 2 is embedded in the first positioning groove of the base 3 and is welded together by an annular weld.

[0029] The top seat 1 is an annular disc with a second positioning groove at its bottom. The upper end of the support leg 2 is embedded in the second positioning groove of the top seat 1 and is welded together by an annular weld.

[0030] The top seat 1 has four arc-shaped bosses spaced apart on its top circumference to support the pump wheel housing plane of the hydraulic torque converter.

[0031] The concave surfaces between the four arc-shaped bosses and the concave surface in the middle of the top seat 1 support the large end face of the guide wheel shaft of the hydraulic torque converter.

[0032] The top seat 1 is connected and fixed to the large end face of the hydraulic torque converter guide wheel shaft by bolts 4 and nuts 5 passing through the top seat 1.

[0033] Eight through holes are distributed on the concave surface in the middle of the top seat 1. The large end face of the hydraulic torque converter guide wheel shaft is fixed by bolts 4 and nuts 5 using the diagonal tightening method.

[0034] The diameter of the base 3 is larger than the diameter of the top seat 1. There are four legs 2, which are evenly distributed to connect the base 3 and the top seat 1.

[0035] like Figure 6 and Figure 7 As shown, the hydraulic torque converter axial movement detection device in this embodiment adopts the symmetrical tightening method and the mean statistical method to measure the axial movement. The process includes three steps:

[0036] Step 1: Inspection phase, such as Figure 6As shown, use a level to check the levelness of the work platform, and place the testing device base 3 upright on the platform. Loosen the nut 5 on the top seat 1 and remove all bolts 4 and nuts 5 for later use.

[0037] Step 2: Detection phase, such as Figure 7 Using a lifting device, the hydraulic torque converter is slowly installed from the top of the top seat 1. The threaded hole on the large end face of the guide wheel shaft is aligned with the threaded hole on the top seat 1, ensuring the large end face of the guide wheel shaft fits against the concave surface of the top seat 1, and the pump wheel housing surface fits against the boss surface of the top seat 1. The top seat 1 is connected to the large end face of the hydraulic torque converter guide wheel shaft by bolts 4 passing through it. A diagonal tightening method is used, with eight nuts 5 used to evenly and symmetrically tighten the eight bolts 4. After tightening the connecting bolts 4, measurements are taken using a ruler.

[0038] Step 3: Statistical Stage. Measure the axial movement four times using a ruler at each of the four grooves on the top seat 1. To ensure accuracy, read the axial movement values ​​from three different points at each groove location. Record the test results as shown in Table 1, and average the readings.
