DETAILED DESCRIPTION
[0032] The invention discloses a torque testing device for a universal ball joint, which is used to solve the technical problem that existing products with universal ball joints lack torque testing before leaving the factory, thereby causing defective products with poor torque to flow into the market.
[0033] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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 work are within the scope of protection of the present invention.

[0035] The fixing jig 2 is installed on the machine 1 to fix the fixed end of the universal ball joint, the rotating component 4 is installed on the machine 1, the clamping jig 3 is connected to the rotating component 4, the clamping jig 3 is used to fix the movable end of the universal ball joint, the torque sensor 5 is connected to the rotating component 4, and the rotating component 4 is used to drive the clamping jig 3 and the movable end of the universal ball joint to swing so that the torque sensor 5 detects the torque of the universal ball joint.
[0036] In the torque test device for universal ball joints of this embodiment, before starting the test, the universal ball joint needs to be placed on the fixing fixture 2, the fixing fixture 2 fixes the fixed end of the universal ball joint, and then the clamping fixture 3 is clamped to the movable end of the universal ball joint, and then the rotating component 4 is controlled to drive the clamping fixture 3 to swing, so that the movable end of the universal ball joint rotates relative to the fixed end of the universal ball joint. At this time, the torque sensor 5 will detect the real-time torque generated when the universal ball joint rotates. Through the above design, the torque detection of the universal ball joint can be realized, which is convenient for manufacturers to sort qualified products and unqualified products, and prevent unqualified universal ball joints from entering the market to affect the user experience.
[0037] Furthermore, the rotating assembly 4 in this embodiment includes a fixed rod 403, a first rotating swing arm 401, a second rotating swing arm 402 and a driving member;
[0038] The first rotating swing arm 401 and the second rotating swing arm 402 are both rotatably connected to the machine platform 1, the fixed rod 403 is connected between the first rotating swing arm 401 and the second rotating swing arm 402, the clamping fixture 3 is installed on the fixed rod 403, the driving member is installed on the machine platform 1, the output shaft of the driving member is connected to the first rotating swing arm 401, and the driving member is used to drive the first rotating swing arm 401 to rotate so that the fixed rod 403 and the second rotating swing arm 402 rotate synchronously.
[0039] It should be noted that the first rotating swing arm 401, the second rotating swing arm 402 and the fixed rod 403 are preferably an integrated structure. Through the above design, the integrity and stability of the rotating component 4 during rotation can be improved, which is conducive to measuring more accurate torque data.
[0040] Furthermore, one end of the torque sensor 5 in this embodiment is connected to the output shaft of the driving member, and the other end is connected to the first rotating swing arm 401 .
[0041] It should be noted that, through the above design, when the rotating assembly 4 drives the clamping fixture 3 and the movable end of the universal ball joint on the clamping fixture 3 to rotate, the torque sensor 5 can detect the torque generated when the universal ball joint rotates.
[0042] Furthermore, the clamping fixture 3 in this embodiment includes a fixed plate 301 and a movable plate 302;
[0043] The movable plate 302 is rotatably connected to the fixed plate 301 , and one end of the movable plate 302 away from the fixed plate 301 is provided with a clamping groove 3022 for clamping the movable end of the universal ball joint.
[0044] It should be noted that, through the above design, when the universal ball joint is placed in the fixed fixture 2, in order to avoid the clamping fixture 3 blocking the above-mentioned placement process, the clamping fixture 3 in this embodiment is configured as a rotatable clamping fixture 3. Specifically, when the universal ball joint needs to be placed in the fixed fixture 2, the movable plate 302 needs to be rotated to a position where it forms an angle of 90 degrees, 70 degrees, or 80 degrees with the fixed plate 301. After the fixed end of the universal ball joint is fixed by the fixed fixture 2, the movable plate 302 is rotated to a position where it forms an angle of 180 degrees with the fixed plate 301. At this time, the engaging groove 3022 on the movable plate 302 is inserted into the movable end of the universal ball joint.
[0045] Furthermore, a silicone pad or a rubber pad is provided on the inner groove wall of the engaging groove 3022 in this embodiment.
[0046] It should be noted that, through the above design, it is possible to prevent the engaging groove 3022 from causing damage to the movable end of the universal ball joint when the movable end of the universal ball joint is fixed.
[0047] Furthermore, the silicone pad or the rubber pad in this embodiment is provided with an anti-slip pattern.
[0048] It should be noted that, through the above design, it is possible to prevent the engagement groove 3022 and the movable end of the universal ball joint from falling off when the rotating component 4 drives the clamping fixture 3 to rotate.
[0049] Furthermore, in this embodiment, there are multiple rotational connection methods for the movable plate 302 and the rotating plate. In one specific implementation, an axis 3011 is fixedly connected to the fixed plate 301, and an arc groove 3021 is opened on the movable plate 302. The arc groove 3021 is slidably connected to the axis 3011. When the axis 3011 and the arc groove 3021 produce relative displacement, the movable plate 302 rotates relative to the fixed plate 301.
[0050] It should be noted that, in order to facilitate control, the movable plate 302 may be connected to a rotating drive member such as a motor to reduce manual operation.
[0051] Furthermore, the fixing fixture 2 in this embodiment includes a pressing plate 202 and a positioning plate 201;
[0052] The positioning plate 201 is provided with a receiving groove for placing the fixed end of the universal ball joint. The pressure plate 202 is rotatably connected to the positioning plate 201. When the pressure plate 202 is driven to rotate to a preset angle, the pressure plate 202 presses the fixed end of the universal ball joint onto the positioning plate 201.
[0053] It should be noted that, through the above design, the fixed end of the universal ball joint can be fully fixed, so as to avoid the fixed end of the universal ball joint being out of position during the torque detection process, thereby preventing inaccurate detection.
[0054] Furthermore, the torque testing device in this embodiment further includes a first bearing and a second bearing disposed on the machine platform 1;
[0055] One end of the first rotating swing arm 401 is rotatably connected to the machine platform 1 through the first bearing, and one end of the second rotating swing arm 402 is rotatably connected to the machine platform 1 through the second bearing.
[0056] It should be noted that, through the above design, the friction resistance of the first rotating arm and the second rotating swing arm 402 can be smaller when rotating, which is conducive to making the torque detection result more accurate.
[0057] Furthermore, in order to enable the operator to intuitively obtain the torque value, the torque testing device of this embodiment also includes a display screen 6 for displaying the torque value;
[0058] The display screen 6 is mounted on the machine platform 1 and is electrically connected to the torque sensor 5 .
[0059] The above is a detailed introduction to a torque testing device for a universal ball joint provided by the present invention.
