[0003] However, existing technology is inconvenient for positioning and fixing different trailing arms. Different trailing arms have different sizes, and choosing different positioning fixtures will result in a large overall investment cost, leading to low applicability of the positioning fixtures. Therefore, it is necessary to design a positioning fixture for automotive balance suspension trailing arms. Utility Model Content

[0006] The clamping assembly includes: reserved slots symmetrically formed at both ends of one side of the fixed base; a fixed slot inside the fixed base on one side of the reserved slot; a positive and negative threaded rod rotatably connected to the inner wall of the fixed slot; threaded blocks threaded to both ends of the surface of the positive and negative threaded rod; a connecting block fixedly connected to one side of the threaded block; a clamping plate fixedly connected to one end of the connecting block; and a friction plate provided at one end of the clamping plate; a miniature drive motor fixedly connected to the lower end of one side of the fixed base; and the output end of the miniature drive motor fixedly connected to one end of the positive and negative threaded rod via a pulley mechanism.

[0007] Preferably, the depth of the reserved groove is greater than the combined thickness of the clamping plate and the friction plate, and the reserved groove, the clamping plate and the friction plate are symmetrically distributed about the vertical central axis of the fixed seat.

[0008] Preferably, the connecting block is L-shaped, and one end of the connecting block is welded to one side of the clamping plate in an integrated structure.

[0009] Preferably, one end of the friction plate is provided with anti-slip patterns at equal intervals, and the anti-slip patterns are arc-shaped.

[0010] Preferably, the inner wall of the fixing groove is provided with a sliding groove, and a slider that slides in cooperation with the inside of the sliding groove is fixedly connected to one side of the threaded block.

[0011] Preferably, one end of the clamping plate is provided with a slot, and a fixing bolt extending into the slot is movably connected to one side of the top of the clamping plate. One end of the friction plate is fixedly connected with a clamping plate, and a bolt hole that is threaded to the bottom end of the fixing bolt is provided on one side of the top of the clamping plate.

[0012] Preferably, the interior of the card plate and the card slot forms a sliding engagement structure, and the card plate and the card slot are convex in shape.

[0013] Preferably, the locking assembly includes: a rotating groove formed inside one side of the upper pressure seat, one end of the upper pressure plate being rotatably connected to the inner bottom wall of the rotating groove, a locking bolt extending to the outside of the rotating groove being fixedly connected to one side of the top of the upper pressure plate; and a locking nut threadedly connected to the surface of the locking bolt.

[0014] Preferably, a friction plate is fixedly connected to one side of the top of the upper pressure seat, and a through hole larger than the cross-sectional area of ​​the locking bolt is opened at the middle position of the friction plate and on one side of the upper pressure seat.

[0016] Compared with related technologies, the automotive balance suspension trailing arm positioning fixture provided by this utility model has the following beneficial effects: 1. By starting the micro drive motor, the pulley mechanism causes the positive and negative threaded rods to rotate, which in turn causes the threaded block to slide and drive the connecting block to slide. This, in turn, causes the clamping plate and friction plate to slide and clamp and fix the groove on one side of the longitudinal arm body. Then, the cylinder is started to lower the sliding plate and drive the connecting column to lower, so that the upper pressure seat and upper pressure plate press and fix the top of the longitudinal arm body. This realizes the positioning and fixing action of longitudinal arm bodies of different sizes, improves the applicability of this positioning fixture, avoids the excessive cost caused by different positioning fixtures for different longitudinal arm bodies, and improves its practicality.

[0017] 2. Tighten the locking nut to completely separate it from the friction plate. Then rotate the upper pressure plate to adjust it according to the shape of the longitudinal arm body, so that the upper pressure plate is as high as possible above the longitudinal arm body. Then rotate the locking nut in the opposite direction to lock it to the top of the friction plate. This achieves the limiting fixation after the upper pressure plate is rotated and adjusted, allowing the upper pressure plate to press a larger area on the top of the longitudinal arm body, thus improving the stability of the upper pressure plate pressing and fixing.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] Example 1 A preferred embodiment of the automotive balance suspension trailing arm positioning fixture provided by this utility model is as follows: Figures 1 to 5 As shown: A positioning fixture for the trailing arm of an automotive balance suspension includes a base 6; a fixed seat 2 fixedly connected to one side of the top of the base 6, a controller 8 fixedly connected to the lower end of one side of the fixed seat 2, a cylinder 9 fixedly connected to one side of the top of the fixed seat 2, a sliding plate 1 fixedly connected to the output end of the cylinder 9, connecting columns 10 fixedly connected to both ends of the bottom end of the sliding plate 1, an upper pressure seat 11 fixedly connected to the bottom end of the connecting columns 10, an upper pressure plate 4 provided on one side of the upper pressure seat 11; a locking assembly 3 assembled between the upper pressure plate 4 and the upper pressure seat 11, the locking assembly 3 being used to limit and fix the upper pressure plate 4 after rotation; a trailing arm body 5 provided at the top of the base 6; and a clamping assembly 7 assembled on the fixed seat 2, the clamping assembly 7 being used to clamp and fix the groove on one side of the trailing arm body 5 of different sizes.

[0023] The clamping assembly 7 includes: reserved slots 701 symmetrically opened at both ends of one side of the fixed base 2; a fixed slot 709 inside the fixed base 2 on one side of the reserved slots 701; a positive and negative threaded rod 707 rotatably connected to the inner wall of the fixed slot 709; threaded blocks 704 threadedly connected to both ends of the surface of the positive and negative threaded rod 707; a connecting block 703 fixedly connected to one side of the threaded block 704; a clamping plate 702 fixedly connected to one end of the connecting block 703; and a friction plate 706 provided at one end of the clamping plate 702; and a micro drive motor 710 fixedly connected to the lower end of one side of the fixed base 2; the output end of the micro drive motor 710 is fixedly connected to one end of the positive and negative threaded rod 707 through a pulley mechanism.

[0024] It should be noted that some existing automotive balance suspension trailing arm positioning fixtures still have certain shortcomings in actual use. Their comparative documents are inconvenient for positioning and fixing different trailing arms. Different trailing arms have different sizes, and choosing different positioning fixtures will result in a large overall investment cost, leading to low applicability of their positioning fixtures.

[0025] In this embodiment, the longitudinal arm body 5 is placed on the top of the base 6, and the groove on one side of the longitudinal arm body 5 is engaged with the fixed seat 2. At the same time, the micro drive motor 710 is started, and the pulley mechanism is used to rotate the positive and negative threaded rod 707. Then, through the threaded engagement of the positive and negative threaded rod 707 and the threaded block 704, the threaded block 704 slides and drives the connecting block 703 to slide. This causes the clamping plate 702 and the friction plate 706 to slide and clamp and fix the groove on one side of the longitudinal arm body 5. Then, the rotation amplitude of the upper pressure plate 4 is adjusted according to the shape of the longitudinal arm body 5. At this time, the locking component 3 is used to limit and fix the upper pressure plate 4 after rotation, so that the upper pressure plate 4 can press a larger area on the top of the longitudinal arm body 5. After that, the cylinder 9 can be started to lower the sliding plate 1 and drive the connecting column 10 to lower, so that the upper pressure seat 11 and the upper pressure plate 4 press and fix the top of the longitudinal arm body 5, realizing the positioning and fixing action of longitudinal arm bodies 5 of different sizes.

[0026] In a further preferred embodiment of the present invention, the depth of the reserved groove 701 is greater than the combined thickness of the clamping plate 702 and the friction plate 706, and the reserved groove 701, the clamping plate 702 and the friction plate 706 are symmetrically distributed about the vertical central axis of the fixed base 2.

[0027] In this embodiment, a deeper reserved groove 701 is used so that the clamping plate 702 and the friction plate 706 can be completely retracted into the reserved groove 701.

[0028] In a further preferred embodiment of the present invention, the connecting block 703 is L-shaped, and one end of the connecting block 703 and one side of the clamping plate 702 are welded together as an integrated structure.

[0029] In this embodiment, the mechanical strength of the connection between the welded clamping plate 702 and the connecting block 703 is improved.

[0030] In a further preferred embodiment of the present invention, anti-slip textures 712 are provided at equal intervals on one end of the friction plate 706, and the anti-slip textures 712 are arc-shaped.

[0031] In this embodiment, the arc-shaped anti-slip texture 712 is used to improve the anti-slip stability of the friction plate 706 and the inner wall of the longitudinal arm body 5.

[0032] In a further preferred embodiment of the present invention, a sliding groove 708 is provided on the inner wall of the fixing groove 709, and a slider 705 that slides and engages with the inside of the sliding groove 708 is fixedly connected to one side of the threaded block 704.

[0033] In this embodiment, the sliding of the slider 705 inside the groove 708 is used to improve the smoothness of the sliding of the threaded block 704.

[0034] In a further preferred embodiment of the present invention, a slot 714 is provided at one end of the clamping plate 702, and a fixing bolt 715 extending into the slot 714 is movably connected to one side of the top of the clamping plate 702. A clamping plate 711 is fixedly connected to one end of the friction plate 706, and a bolt hole 713 that is threadedly engaged with the bottom end of the fixing bolt 715 is provided on one side of the top of the clamping plate 711.

[0035] In this embodiment, the fixing bolt 715 is loosened with a screwdriver or other tools until it is completely disengaged from the bolt hole 713. Then, the friction plate 706 is pushed so that the clamping plate 711 slides out of the slot 714, thus achieving the sliding disassembly of the friction plate 706. During installation, the clamping plate 711 is slid into the slot 714, and the fixing bolt 715 is tightened into the bolt hole 713, thus achieving a secure installation between the friction plate 706 and the clamping plate 702.

[0036] In a further preferred embodiment of the present invention, a sliding engagement structure is formed between the interior of the card plate 711 and the card slot 714, and the shapes of the card plate 711 and the card slot 714 are convex.

[0037] In this embodiment, the sliding engagement between the convex locking plate 711 and the slot 714 improves the stability of the sliding installation between the friction plate 706 and the clamping plate 702.

[0038] Example 2 Based on Embodiment 1, a preferred embodiment of the automotive balance suspension trailing arm positioning fixture provided by this utility model is, for example... Figures 1 to 5 As shown: The locking assembly 3 includes: a rotating groove 302 formed inside one side of the upper pressure seat 11; one end of the upper pressure plate 4 is rotatably connected to the inner bottom wall of the rotating groove 302; a locking bolt 304 extending to the outside of the rotating groove 302 is fixedly connected to one side of the top of the upper pressure plate 4; and a locking nut 303 threadedly connected to the surface of the locking bolt 304.

[0039] In this embodiment, by loosening the locking nut 303 until it is completely separated from the friction plate 301, the upper pressure plate 4 can be rotated to position it as directly above the longitudinal arm body 5 as possible. Then, the locking nut 303 is tightened in the opposite direction so that its bottom end fits against the top end of the friction plate 301. This achieves the limiting and fixing of the upper pressure plate 4 after rotation, allowing the upper pressure plate 4 to press against the top end of the longitudinal arm body 5 over a larger area, thus improving the stability of the longitudinal arm body 5.

[0040] In a further preferred embodiment of the present invention, a friction plate 301 is fixedly connected to one side of the top of the upper pressure seat 11, and a through hole larger than the cross-sectional area of ​​the locking bolt 304 is opened at the middle position of the friction plate 301 and one side of the upper pressure seat 11.

[0041] In this embodiment, the friction plate 301 is used to improve the tightness of the locking nut 303 after it is tightened.

[0042] In a further preferred embodiment of the present invention, one side of the upper pressure seat 11 is arc-shaped, and one side of the upper pressure seat 11 is slidably connected to one side of the surface of the fixed seat 2.

[0043] In this embodiment, the smoothness of the upper pressure seat 11 sliding up and down is improved by utilizing the sliding between the upper pressure seat 11 and the fixed seat 2.

[0044] In summary, the locking assembly 3 allows the upper pressure plate 4 to be rotated and adjusted, and the clamping assembly 7 and cylinder 9 enable the clamping and fixing of longitudinal arm bodies 5 of different sizes, thus improving its applicability.
