Description

Technical Field

[0001] The utility model belongs to the technical field of automobile testing, and in particular relates to an off-line testing device for an electronic torque manager. Background Art

[0002] The Electronic Torque Manager 01 is a core component of the four-wheel drive system. It is installed between the vehicle's rear final drive and rear wheels, enabling power transfer and disconnection between the two. Normally, the Electronic Torque Manager 01 is disconnected, depriving the rear wheels of power. In this state, the vehicle operates in two-wheel drive mode, achieving greater fuel efficiency. When rear-wheel drive is required, the vehicle can be switched from two-wheel drive to four-wheel drive simply by controlling the position of the motor rotor in the Electronic Torque Manager 1. The assembly quality of the Electronic Torque Manager 01 directly impacts the performance of the vehicle's four-wheel drive system. Therefore, after assembly, the Electronic Torque Manager 01 undergoes end-of-line testing to prevent unqualified Electronic Torque Manager 01 components from entering the assembly line and impacting vehicle performance.

[0003] At present, the offline test items of the electronic torque manager 01 mainly include air tightness testing and functional testing, but these two offline test items are carried out separately through corresponding testing devices. During the testing process, if a certain offline test item of the electronic torque manager 01 is completed, the electronic torque manager 01 needs to be transferred to another offline test item for testing, which greatly affects the testing efficiency of the electronic torque manager 01. Utility Model Content

[0006] Preferably, the offline test equipment includes a display, which is connected to the functional test platform for the convenience of users.

[0007] Preferably, the offline test equipment includes a second horizontal drive mechanism that drives the positioning seat to switch between the first station and the test station; in this way, the material transfer robot can be used to connect the first station with the assembly conveyor line of the electronic torque manager to achieve continuity of assembly and testing.

[0008] Preferably, the offline test equipment includes a clamping mechanism for clamping or releasing the electronic torque manager; the clamping mechanism can switch between the second workstation, the test workstation and the third workstation, the second workstation is located directly below the test workstation, and the third workstation is located directly above the test workstation; the offline test equipment is arranged on the assembly conveyor line; the assembly conveyor line is used to convey the assembled electronic torque manager to the second workstation, and remove the tested electronic torque manager from the second workstation; since the offline test assembly of the present application can be directly arranged on the assembly conveyor line of the electronic torque manager and become a part of the assembly conveyor line, compared with the traditional arrangement independent of the assembly conveyor line, it not only improves the continuity of assembly and testing, but also facilitates the return of unqualified electronic torque managers to the assembly line for adjustment, thereby reducing rework costs.

[0009] Preferably, the assembly conveyor line is a roller conveyor line to facilitate long-distance transportation at low cost.

[0010] Preferably, the lifting drive mechanism and each horizontal drive mechanism are linear motors or cylinders or hydraulic cylinders.

[0011] Preferably, the clamping mechanism is an electric clamp or a pneumatic clamp, and the user can choose according to needs.

Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of this utility model without substantially changing the technical content.

[0029] like Figure 1 As shown, the electronic torque manager 01 is an important component unit of the four-wheel drive transmission system, which includes a manager housing 011, a coaxially arranged input shaft 012 and an output shaft 013, and a motor 016, and the manager housing 011 has a first opening and a second opening arranged opposite to each other; wherein, the input shaft 012 is passed through the manager housing 011 through the first opening, and one end of the input shaft 012 is located outside the manager housing 011 and is connected to the rear main reducer, and the other end of the input shaft 012 is coaxially fixed with an inner hub body; the output shaft 013 is rotatably mounted in the manager housing 011 through a bearing, and the end of the output shaft 013 away from the input shaft 012 is used to connect to the rear wheel half shaft inserted from the second opening, and at the same time, an oil seal 017 needs to be provided at the second opening to keep the interior of the electronic torque manager 01 lubricated and clean; the output shaft 01 3 is coaxially fixed with an outer hub body which is sleeved on the inner hub body, and a clutch plate group 014 is provided between the inner hub body and the outer hub body, and a ramp ball track assembly 015 and an elastic member for resetting the ramp ball track assembly 015 are provided on the side of the clutch plate group 014 away from the second opening; the motor 016 controls the degree of compression of the clutch plate group 014 through the ramp ball track assembly 015 to change the torque value transmitted from the input shaft 012 to the output shaft 013; therefore, the torque transmission value can be controlled by controlling the rotor position of the motor 016; since the rotor position of the motor 016 is controlled by the motor current, the current of the motor 016 is controlled according to a predetermined rule so that the motor 016 outputs the corresponding rotor position under each current, and by judging the rotor position, it can be detected whether the functional test of the electronic torque manager 011 is qualified. In order to facilitate the connection between the electronic torque manager 01 and the electronic control unit of the electronic torque manager 01, the motor 016 of the electronic torque manager 01 needs to be provided with a motor connector, and the motor connector needs to be arranged perpendicular to the input shaft 017 to reduce the lateral space occupied inside the vehicle.

[0030] Because the electronic torque manager 01 is assembled from multiple components, it requires end-of-line testing, including air tightness testing and functional testing, after assembly to ensure that the assembled electronic torque manager 01 meets requirements and does not leak or otherwise fail to meet quality standards. Currently, air tightness testing and functional testing of the electronic torque manager 01 are performed separately, which is not conducive to improving the efficiency of end-of-line testing of the electronic torque manager 01. Therefore, the present invention provides an end-of-line testing device that integrates air tightness testing and functional testing. This device can complete air tightness testing and functional testing of the electronic torque manager 01 without requiring secondary transport of the electronic torque manager 01, thereby improving the efficiency of end-of-line testing of the electronic torque manager 01.

[0031] Since the electronic torque manager 01 is in a vertical state during the airtightness test, in the following embodiment, the axial direction of the input shaft 012 is defined as the up and down direction. Based on this, the first opening is the lower end opening and the second opening is the upper end opening.

[0032] like Figures 2 to 8 As shown, the off-line test equipment of the electronic torque manager involved in this application includes a support frame 1, a controller, a positioning seat 2 arranged on the support frame 1, an airtightness detection device and a functional testing device.

[0033] The positioning seat 2 is used to support and position the electronic torque manager 01; specifically, a socket 21 for inserting the input shaft 012 is provided on the top of the positioning seat 2, and a sealing ring is provided between the positioning seat 2 and the electronic torque manager 01. In this way, when the electronic torque manager 01 is pressed against the positioning seat 2, the sealing ring will deform and seal the lower end opening of the electronic torque manager 01.

[0034] The airtightness detection device includes an airtightness detector, an auxiliary pressing assembly 3 and a first lifting drive mechanism 4; wherein the auxiliary pressing assembly 3 includes a pressing sleeve 31, a sealing rod 32 inserted in the pressing sleeve 31 and a second lifting drive mechanism 33 that drives the sealing rod 32 to move up and down relative to the pressing sleeve 31, and the first lifting drive mechanism 4 and the second lifting drive mechanism 33 are both controlled by a controller; the pressing sleeve 31 is connected to the movable part of the first lifting drive mechanism 4 through a fixing frame 35, and the pressing sleeve 31 is used to press the electronic torque manager 01 onto the positioning seat 2 to seal the lower end opening of the electronic torque manager 01; the sealing rod 32 is used to The oil seal 017 of the electronic torque manager 01 cooperates to seal the upper opening of the electronic torque manager 01; since both the lower opening and the upper opening of the electronic torque manager 01 are sealed, a test chamber is formed inside the electronic torque manager 01; in addition, a first air hole 321 is vertically penetrated within the sealing rod 32, the upper end of the first air hole 321 is connected to the air tightness tester, and the lower end of the first air hole 321 is used to connect to the test chamber of the electronic torque manager 01; in this way, the air tightness tester can fill a certain amount of gas into the test chamber through the first air hole 321 to perform an air tightness test on the electronic torque manager 01.

[0035] The functional testing device includes a functional testing platform, a test plug-in 51 connected to the functional testing platform wiring harness, and a first horizontal drive mechanism 6, wherein the first horizontal drive mechanism 6 is connected to the controller; in this way, the test plug-in 51 can be connected to or separated from the motor 016 on the electronic torque manager 01 under the drive of the first horizontal drive mechanism 6; when the test plug-in 51 is connected to the motor connector on the motor 016, the functional testing platform can control and test the electronic torque manager 01 through the test plug-in 51 to obtain the working quality of the electronic torque manager 01 under different states.

[0036] It is understandable that there are various types of air tightness testers, including but not limited to quantitative air tightness testers, flow air tightness testers, or differential pressure air tightness testers.

[0037] In order to facilitate users to intuitively obtain relevant test parameters and test results of the functional test process, a display connected to the functional test platform can be additionally provided.

[0038] In a preferred embodiment, in order to facilitate the docking and separation of the airtightness detector and the sealing rod 32, as shown in FIG. Figure 7 and Figure 8As shown, a connecting seat 34 is detachably fixed to the top of the sealing rod 32, and a horizontally arranged second air hole is provided in the connecting seat 34. One end of the second air hole is connected to the first air hole 321, and the other end of the second air hole is provided with an air pipe joint for connecting to an air tightness detector (the air pipe of the air tightness detector is a hose); the second lifting drive mechanism 33 is connected to the top of the connecting seat 34, so that the sealing rod 32 can be driven to move up and down through the connecting seat 34.

[0039] In a preferred embodiment, in order to achieve accurate positioning of the electronic torque manager 01 on the positioning seat 2 and avoid angular deviation that affects the connection of the test plug-in 51, a positioning pin can be set at one of the lower end of the electronic torque manager 01 and the upper end of the positioning seat 2, and a positioning hole that cooperates with the positioning pin can be set at the other end; the electronic torque manager 01 can be accurately positioned by utilizing the cooperation between the positioning pin and the positioning hole.

[0040] In addition, in order to ensure the stability of the offline test equipment, the first lifting drive mechanism 4 should be set as centrally as possible (that is, the first lifting drive mechanism 4 should be located as close to the vertical center line of the support frame 1 as possible). At this time, the test station must be located near the vertical center line of the support frame 1.

[0041] In some embodiments, the positioning seat 2 is directly fixed at the test station, and the test station is located at the intersection of the movement path of the auxiliary clamping assembly 3 and the movement path of the test plug-in 51; at this time, the working process of the entire offline test equipment is as follows: the electronic torque manager 01 is placed on the positioning seat 2, and then the auxiliary clamping assembly 3 is moved down to the test station under the action of the first lifting mechanism 4, so that the electronic torque manager 01 to be tested is pressed on the positioning seat 2 using the clamping sleeve 31; then, the sealing rod 32 moves down under the action of the second lifting mechanism 33 and seals the oil seal 017 of the electronic torque manager 01. At the same time, the test plug-in 51 is inserted into the motor 016 of the electronic torque manager 01 under the action of the first horizontal drive mechanism 6; finally, the electronic torque manager 01 can be tested using an airtightness detector and a functional test platform.

[0042] In other embodiments, Figure 9 As shown, a second horizontal drive mechanism 8 connected to the controller is provided on the support frame 1, and the second horizontal drive mechanism 8 drives the positioning seat 2 to switch between the test station and the first station; at this time, the first station is the loading station, and the loading station can be connected to the assembly conveyor line of the electronic torque manager 01 through a material transfer robot to realize the automatic assembly and detection of the electronic torque manager 01.

[0043] Specifically, the working process of the entire off-line test equipment is as follows: the electronic torque manager 01 to be tested is positioned on the positioning seat 2 at the first station, and the positioning seat 2 is moved to the test station by the second horizontal drive mechanism 8; then, the auxiliary clamping assembly 3 is moved down to the test station under the action of the first lifting mechanism 4, so that the electronic torque manager 01 to be tested is pressed onto the positioning seat 2 using the clamping sleeve 31; then, the sealing rod 32 is moved down under the action of the second lifting mechanism 33 and seals the oil seal 017 of the electronic torque manager 01. At the same time, the test plug-in 51 is inserted into the motor 016 of the electronic torque manager 01 under the action of the first horizontal drive mechanism 6; finally, the electronic torque manager 01 can be tested using an airtightness detector and a functional test platform.

[0044] Since the material transfer robot has a complex structure and a high cost, in order to realize the assembly conveyor line of the offline test equipment and the electronic torque manager 01 at a low cost, the present application preferably adds a second horizontal drive mechanism 8 connected to the controller on the support frame 1 (such as Figure 9 As shown) and the clamping mechanism 7 connected to the movable end of the first driving lifting mechanism 4 (as shown Figure 1 and Figure 7 as shown); wherein, the second horizontal drive mechanism 8 is used to drive the positioning seat 2 to switch between the first station and the test station; the clamping mechanism 7 is controlled by the controller, and the clamping mechanism 7 can switch between the second station, the test station and the third station; the second station is located directly below the test station, and the third station is located directly above the test station; when in use, the offline test equipment is set on the assembly conveyor line 9, so as to utilize the assembly conveyor line 9 to transport the assembled electronic torque manager 01 to the second station and remove the tested electronic torque manager 01 from the second station; the assembly conveyor line 9 is a roller conveyor line for circular transportation to reduce transportation costs.

[0045] At this time, the first station is the avoidance station, and the second station is the loading station. The working process of the entire offline test equipment is as follows: the positioning seat 2 is in the first station, and the assembly conveyor line 9 moves the assembled electronic torque manager 01 to the second station; the first lifting drive mechanism 4 drives the clamping mechanism 7 to move down to the second station to clamp the electronic torque manager 01; then, the first lifting drive mechanism 4 drives the clamping mechanism 7 to move up to the third station, so that the electronic torque manager 01 is located above the test station; then, the second horizontal drive mechanism 8 moves the positioning seat 2 to the test station, and the first lifting drive mechanism 4 drives the clamping mechanism 7 and the auxiliary clamping assembly 3 to move down, so that the electronic torque manager 01 is placed on the positioning seat 2 and the electronic torque manager to be tested is clamped by the clamping sleeve 31. 01 is pressed against the positioning seat 2; then, the sealing rod 32 moves downward under the action of the second lifting mechanism 33 and seals the oil seal 017 of the electronic torque manager 01. At the same time, the test plug-in 51 is inserted into the motor 016 of the electronic torque manager 01 under the action of the first horizontal driving mechanism 6; finally, the electronic torque manager 01 can be tested using the air tightness tester and the functional test platform; after the test is completed, only the reverse operation is required to place the tested electronic torque manager 01 at the second station, so that the electronic torque manager 01 tested at the second station can be transported to the marking station for marking operation or directly transported to the final inspection station by using the assembly conveyor line (that is, qualified products are transported to the final inspection station after marking at the marking station, and unqualified products are directly transported to the final inspection station).

[0046] It is understandable that in order to simplify the operating process, the stroke position of the clamping mechanism 7 needs to be consistent with the stroke position of the auxiliary clamping component 3, that is, when the auxiliary clamping component 3 clamps the electronic torque manager 01, the clamping mechanism 7 can just clamp or release the electronic torque manager 01.

[0047] It can be understood that each lifting drive mechanism and each horizontal drive mechanism is a linear motor or a cylinder or a hydraulic cylinder or other devices that can realize linear reciprocating motion, and there is no limitation on this; since the clamping mechanism 7 needs to switch between three workstations, in order to ensure that the clamping mechanism 7 can be accurately moved to each workstation, it is necessary to additionally be equipped with a position sensor, and the structure and form of the position sensor include but are not limited to a contact sensor or a distance sensor.

[0048] It is understandable that the clamping mechanism 7 is an electric clamp or a pneumatic clamp, which is not limited.

[0049] The clamping mechanism 7 can be implemented in a manner including, but not limited to, swinging clamping or close clamping. Close clamping is preferred in this embodiment. Specifically, the clamping mechanism 7 includes two clamping members and a spacing adjustment assembly (e.g., bidirectional threaded rod adjustment, intermediate gear + dual rack adjustment, etc.) for adjusting the spacing between the two clamping members.

[0050] In addition, in order to facilitate the movement of the offline test equipment, casters with brakes can be provided at the bottom of the support frame 1 and / or lifting ears can be provided at the top of the support frame 1.

[0051] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person skilled in the art without departing from the spirit and technical concept disclosed in the present invention shall be covered by the claims of the present invention.
