[0023] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.
[0024] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.
[0025] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.
[0026] refer to Figures 1 to 6 The torque converter hanger error prevention tooling according to a preferred embodiment of the present invention will be described in detail below. The torque converter hanger error prevention tooling is used to be inserted into the corresponding hanger 90 to prevent the operator from misplacing, failing to place or taking the wrong hanger 90. Figure 2As shown, the outer diameter of the insertion part of each type of the hanger 90 is set differently. A hanging groove 901 is formed on the side of the hanger 90, and a slot 902 connected to the hanging groove 901 is formed on the bottom of the hanger 90. The slot 902 of the hanger 90 with a larger outer diameter of the insertion part is set larger than the slot 902 of the hanger 90 with a smaller outer diameter of the insertion part, so that each hanger 90 can stably hang the corresponding torque converter from above, but cannot stably hang other torque converters.
[0027] like Figure 1 As shown, the torque converter hanger error-proofing tool comprises at least one mounting seat 10 , a plurality of error-proofing components 20 and a sensing component 20 .
[0028] The error-proofing components 20 are provided in the same number as the hangers 90, and the sizes of each error-proofing component 20 are different. Each size of the error-proofing component 20 corresponds to a size of the hanger 90, so that each hanger 90 is placed in a corresponding error-proofing component 20.
[0029] The sensing component 30 includes a plurality of sensing members 31, which are arranged to be installed on the error-proofing component 20, and each of the sensing members 31 can sense the hanger 90 located in the corresponding error-proofing component 20, and communicate to a device for taking the hanger 90 to lock the hanger 90 when sensing that an operator has taken the wrong hanger 90, so as to prevent the operator from using the wrong hanger 90 to lift a non-corresponding torque converter.
[0030] Preferably, if Figure 1 and Figure 3As shown, each of the error-proofing components 20 includes a placement sleeve 21 and a positioning block 22, wherein the placement sleeve 21 is mounted on the mounting seat 10 and forms a placement slot 2101, the placement slot 2101 is used to be inserted from above by the sling 90, and the size of the placement slot 2101 of each error-proofing component 20 is set to be adapted to the outer diameter of an insertion portion of the sling 90. The positioning block 22 is vertically mounted on the inner wall of the placement sleeve 21 forming the placement slot 2101, and the height of the positioning block 22 is less than the notch height of the sling slot 901, so that the sling 90 can be fully inserted into the placement slot 2101. Each of the positioning blocks 22 is configured to be adapted to the slot hole 902 of the corresponding hanger 90, and the width of the positioning block 22 of the error-proofing component 20 of the large-sized placement slot 2101 is configured to be larger than the width of the positioning block 22 of the error-proofing component 20 of the small-sized placement slot 2101, and the width of the positioning block 22 of the error-proofing component 20 of the large-sized placement slot 2101 is larger than the size of the slot hole 902 of the hanger 90 corresponding to the small-sized placement slot 2101, so that only the corresponding hanger 90 can be inserted into the corresponding placement slot 2101.
[0031] Those skilled in the art can understand that each size of the error-proofing component 20 corresponds to a size of the hanger 90, that is, the size of the placement groove 2101 of the error-proofing component 20 corresponds to the outer diameter of the insertion part of the hanger 90, and the width of the positioning block 22 corresponds to the size of the slot hole 902 of the hanger 90. When the outer diameter of the insertion part of the hanger 90 is set to be larger, the size of the hanging groove 901 of the hanger 90 is also set to be larger. At the same time, the width of the positioning block 22 of the anti-mistake component 20 of the large placement groove 2101 is greater than the size of the slot hole 902 of the hanger 90 corresponding to the small placement groove 2101. In this way, the hanger 90 with a large outer diameter of the insertion part cannot be inserted into the small placement groove 2101. Although the hanger 90 with a small outer diameter of the insertion part seems to be able to be inserted into the large placement groove 2101, because the size of the slot hole 902 formed by the hanger 90 with a small outer diameter of the insertion part is smaller than the width of the positioning block 22 set in the large placement groove 2101, the hanger 90 with a small outer diameter of the insertion part cannot actually be inserted into the large placement groove 2101, which can prevent the hanger 90 from being placed in the wrong anti-mistake component 20.

[0035] The third error-proofing component 20C includes a third placement sleeve 21C and a third positioning block 22C, wherein the third placement sleeve 21C is installed on the mounting seat 10 and forms a third placement groove 2101C, the third placement groove 2101C is used to be inserted from above by the third sling 90C, and the size of the third placement groove 2101C is set to be adapted to the outer diameter of the insertion part of the third sling 90C and is larger than the outer diameter of the insertion part of the first sling 90A and the second sling 90B. The third positioning block 22C is vertically installed on the inner wall of the placement sleeve 241 forming the third placement groove 2101C, and the notch height of the third sling groove 901C is greater than the height of the third positioning block 22C, so that the third sling 90C can be fully inserted into the third placement groove 2101C.

[0038] More preferably, the sensor 311 is communicatively connected to the device for removing the sling 90 , and when the sling 90 is in the placement slot 2101 and the operator takes the wrong sling 90 , the sensor 311 sends a message to the device for removing the sling 90 to stop removing the sling 90 .
