Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling and provides an anti-roll connecting rod assembly device. Background Technology

[0002] There are several significant technical challenges in the current assembly process of anti-roll connecting rods. Firstly, existing anti-roll connecting rod assembly fixtures have issues with securing the node mandrel. Because the fixture clearance cannot be adjusted according to changes in the mandrel thickness, inaccurate positioning easily occurs when the mandrel thickness decreases. Conversely, this securing method is equally unsuitable when the mandrel thickness increases. This not only increases the workload of measurement and adjustment after assembly but also makes it difficult to ensure that the overall length of the assembled connecting rod meets standard requirements.

[0003] Secondly, the assembly of the rod end bearing also faces many challenges. Currently, the rod end bearing cap requires manual tightening, which is not only complex and labor-intensive, but also results in excessive clearance between the rod end bearing and the cap, directly affecting the accuracy and reliability of the assembly. This excessive clearance prevents the required precision in positioning the rod end bearing.

[0004] Finally, the existing tooling lacks accuracy in controlling the distance between the node mandrel fixing groove and the rod end bearing axis, making effective locking impossible and thus failing to guarantee the perpendicularity between the node mandrel and the rod end bearing axis. This situation not only increases the adjustment frequency during assembly but may also seriously affect the consistency and repeatability of the tooling, limiting its applicability to node mandrels of a specific thickness.

[0029] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0030] like Figures 1 to 2 As shown, this utility model embodiment provides an anti-roll linkage assembly device, comprising:

[0031] Base 100;

[0032] The first clamping assembly is disposed on the base 100. The first clamping assembly includes a pair of clamping grooves 102. The clamping grooves 102 are used to place the node mandrel of the anti-roll link. A first clamping member 104 is disposed in the clamping grooves 102 for clamping the node mandrel in the clamping grooves 102.

[0033] The second clamping assembly is disposed on the base 100. The second clamping assembly includes a clamping rod 106, which is used to clamp the rod end bearing of the anti-roll link between the clamping rod 106 and the base 100.

[0034] According to the anti-roll connecting rod assembly device provided in this embodiment of the utility model, the clamping groove 102 of the first clamping component, through the synergistic action of the abutment plate 108 and the first clamping member 104, firmly fixes the node mandrel, avoiding positioning offset caused by changes in mandrel thickness; the second clamping component, through the rigid clamping of the "clamping rod 106-base 100", eliminates the wobbling clearance of the rod end bearing. The cooperation of the two ensures that the perpendicularity and spacing of the axis of the node mandrel and the rod end bearing meet the design requirements, reducing data deviation after assembly. The adjustable first clamping member 104 can adapt to node mandrels of different thicknesses without replacing parts, saving the time of changing and adjusting traditional tooling; the rapid lifting and lowering operation of the clamping rod 106 simplifies the fixing process of the rod end bearing, replaces the laborious operation of manually tightening the pressure cap, reduces the labor intensity of operators, and shortens the assembly time of a single connecting rod. The rigid structure and standardized clamping force of the device ensure consistent assembly conditions for each batch of connecting rods, avoiding individual differences caused by manual operation. The stable fixing state of the node mandrel and rod end bearing reduces positional changes during assembly, ensuring that the overall length of the connecting rod meets the standard and reducing the frequency of subsequent adjustments. The adjustable clearance design of the first clamping component makes the device compatible with various specifications of node mandrels, and the height-adjustable feature of the second clamping component adapts to rod end bearings of different sizes, breaking through the limitation of the single adaptability of traditional tooling and improving the versatility and economy of the equipment. The contact area between the first clamping member 104 and the node mandrel can be equipped with an anti-slip layer or flexible material to prevent scratching the mandrel surface during clamping. The pressing part 118 of the clamping rod 106 adopts a structure adapted to the bearing contour, reducing bearing deformation or damage caused by local pressure concentration and ensuring the integrity of the workpiece.

[0035] Please continue reading Figure 1 and Figure 2 The anti-roll connecting rod assembly device provided in this embodiment of the utility model achieves precise positioning and fixation of the node mandrel and the rod end bearing through a dual-component collaborative clamping design.

[0036] The base 100 is a horizontal platform made of rigid metal sheet, serving as the mounting base for the entire device. Its surface is milled to ensure flatness and provide stable support for all components. Positioning reference lines are marked on the base 100 to assist in calibrating the relative positions of the first and second clamping components.

[0037] The first clamping assembly is used to fix the node mandrel of the anti-roll link, including a pair of clamping grooves 102 and a first clamping member 104. The clamping groove 102 is formed by the opposing abutment plate 108 and the mounting plate 110, and the groove width is slightly larger than the maximum diameter of the node mandrel; the first clamping member 104 is mounted on the mounting plate 110 and can extend and retract in the horizontal direction. By moving toward the abutment plate 108, it clamps the node mandrel in the groove and is suitable for node mandrels of different thicknesses.

[0038] The second clamping assembly is used to fix the rod end bearing of the anti-roll connecting rod, including a clamping rod 106 and a matching mounting structure. The clamping rod 106 is vertically arranged above the base 100 and can be raised and lowered axially. After the rod end bearing is placed in the corresponding position on the base 100, the clamping rod 106 moves downward and presses it against the surface of the base 100 to form a "rod-base" clamping and fixing, ensuring that the bearing does not shift during assembly.

[0039] The first and second clamping components are spaced apart along the length of the base 100, with the spacing adapted to the overall length of the anti-roll connecting rod, ensuring precise alignment of the node mandrel and the axis of the rod end bearing. Adjustable clamping: the extension stroke of the first clamping component 104 is adjustable to accommodate variations in the thickness of different node mandrels; the lifting height of the clamping rod 106 is adjustable to accommodate the clamping requirements of rod end bearings of different sizes. The surface of the base 100 has a positioning boss or groove corresponding to the position of the rod end bearing, which matches the outer ring contour of the bearing, achieving initial positioning before being fixed by the clamping rod 106, thus improving positioning accuracy.

[0040] According to one embodiment of the present invention, the first clamping assembly further includes:

[0041] Abutment plate 108 is disposed on base 100;

[0042] Mounting plate 110 is arranged opposite to abutment plate 108 and is disposed on base 100. First clamping member 104 is mounted on mounting plate 110, and clamping groove 102 is formed between mounting plate 110 and abutment plate 108.

[0043] In one embodiment of this utility model, the abutment plate 108 is a rectangular metal plate, which is vertically fixed to the surface of the base 100 by bolts. The plate surface is flat and perpendicular to the base 100. The mounting plate 110 is parallel to the abutment plate 108, with a distance slightly larger than the diameter of the largest specification node mandrel. The bottom is fixed to the base 100 by reinforcing ribs. The first clamping member 104 is horizontally inserted through the center hole of the mounting plate 110, with its end aligned with the center area of ​​the abutment plate 108. The gap between the mounting plate 110 and the abutment plate 108 forms a clamping groove 102, and the edge of the groove is chamfered to facilitate the insertion of the node mandrel.

[0044] The parallel-arranged abutment plates 108 and mounting plates 110 form a regular clamping groove 102, providing rigid support on both sides for the node mandrel, avoiding positioning offset as is common in traditional open tooling, and ensuring that the mandrel's centerline is perpendicular to the surface of the base 100. The reinforcing ribs connecting the mounting plate 110 and the base 100, along with the fixed design of the abutment plates 108, prevent the clamping groove 102 from deforming under clamping force, ensuring stable positioning accuracy after long-term use. The open design of the groove facilitates quick insertion of the node mandrel, and combined with the precise alignment of the first clamping member 104, reduces calibration time during clamping and improves operational efficiency.

[0045] According to one embodiment of the present invention, the first clamping assembly further includes a driving member 112, which is convexly connected to the first clamping member 104 to drive the first clamping member 104 to move closer to or away from the abutment plate 108.

[0046] In one embodiment of this utility model, the driving component 112 is a pneumatic cylinder or a manual screw jack, fixed to the side of the mounting plate 110 opposite to the abutment plate 108. If it is a pneumatic cylinder, its piston rod is connected to the first clamping component 104 through a floating joint, and the cylinder body is equipped with a speed regulating valve to control the extension and retraction speed; if it is a manual screw structure, the driving component 112 includes a handwheel, a worm gear, and a worm wheel. The worm wheel meshes with the screw of the first clamping component 104, and the screw is extended and retracted by rotating the handwheel. The travel of the first clamping component 104 can be set to be relatively large, covering the thickness range of common node mandrels.

[0047] The pneumatic drive unit 112 can achieve one-button clamping / releasing via a control valve, reducing manual operation intensity and making it particularly suitable for mass production scenarios, thus improving assembly efficiency. The output force of the drive unit 112 can be controlled by air pressure regulation or the mechanical gain of the screw drive, avoiding excessive clamping force that could deform the node mandrel, or insufficient clamping force that could cause loose positioning. The adjustable travel stroke allows the gap of the clamping groove 102 to be flexibly adjusted according to the thickness of the node mandrel, enabling compatibility with different product models without changing tooling, thus expanding the range of applications.

[0048] According to one embodiment of the present invention, the first clamping member 104 is provided with an anti-slip layer at one end facing the abutment plate 108.

[0049] In one embodiment of this utility model, the anti-slip layer is made of vulcanized rubber or polyurethane and is fixed to the end face of the first clamping member 104 by an adhesive. The surface of the anti-slip layer is processed with a diamond-shaped grid pattern, and the area in contact with the node mandrel is an arc-shaped concave surface, the curvature of which matches the outer radius of the mandrel. The edge of the anti-slip layer is flush with the end face of the first clamping member 104, without any protrusions or burrs.

[0050] The mesh pattern significantly increases the friction on the contact surface with the node mandrel, preventing the mandrel from rotating or sliding axially due to external forces during assembly, thus ensuring positioning accuracy. The elastic anti-slip layer absorbs the instantaneous impact force when the drive component 112 clamps, avoiding damage to the node mandrel surface caused by rigid contact and protecting workpiece accuracy. The elastic deformation of the anti-slip layer can adapt to minor unevenness on the node mandrel surface, ensuring uniform contact area and avoiding indentations caused by localized pressure concentration.

[0051] According to one embodiment of the present invention, the second clamping assembly further includes:

[0052] Mounting bracket 114 is mounted on the base;

[0053] Mounting rod 116 is mounted on mounting base 114, and clamping rod 106 is movably mounted on mounting rod 116.

[0054] In one embodiment of this utility model, the mounting base 114 is generally L-shaped and is fixed to the base 100 by bolts. The mounting rod 116 is a cylindrical metal rod that is vertically connected to the mounting base 114.

[0055] The rigid connection between the mounting base 114 and the mounting rod 116 provides stable support for the clamping rod 106, reduces wobbling during clamping, and ensures that the clamping force of the rod end bearing is evenly distributed.

[0056] According to one embodiment of the present invention, a clamping part 118 is provided at one end of the clamping rod 106 facing the base 100.

[0057] In one embodiment of this utility model, the clamping part 118 is a circular metal clamping block or an elastic clamping block, which is detachably connected to the bottom end of the clamping rod 106 by bolts. The bottom surface of the clamping block is machined with a concentric annular groove, and the edges are rounded. The diameter of the clamping block is slightly smaller than the outer ring diameter of the rod end bearing to ensure that the pressure is concentrated on the outer ring of the bearing and to avoid damage to the internal rolling elements.

[0058] The large-area clamping block ensures that the clamping force is evenly distributed to the outer ring of the rod end bearing, avoiding localized pressure concentration caused by an excessively small clamping rod 106 end, and preventing deformation of the bearing outer ring. The detachable design allows for replacement of the clamping block according to the rod end bearing size; simply changing the clamping block adapts to various product specifications, reducing tooling costs. The rounded edges and annular groove design prevent rigid friction between the clamping block and the bearing dust cover or seal, reducing the risk of bearing damage during assembly.

[0059] According to one embodiment of the present invention, a positioning protrusion 120 is formed on the mounting base 114, and a positioning groove is provided on the pressing part 118 at a position corresponding to the positioning protrusion 120.

[0060] In one embodiment of this utility model, the positioning protrusion 120 is a cylindrical boss on the top surface of the mounting base 114, integrally formed with the mounting base 114, and its axis is concentric with the clamping rod 106. The positioning groove is a circular groove on the bottom surface of the clamping part 118. When the clamping rod 106 descends to the clamping position, the positioning protrusion 120 is embedded in the positioning groove to form an axial and radial positioning fit.

[0061] The engagement of the positioning protrusion 120 and the positioning groove strictly limits the radial position of the clamping part 118, ensuring that the clamping rod 106 coincides with the axis of the rod end bearing, thus preventing bearing deformation caused by eccentric clamping. The fitting structure resists the torque generated during clamping, preventing the clamping part 118 from deflecting due to lateral forces, and ensuring that the rod end bearing is always in the correct positioning posture. The guiding effect of the protrusion and groove allows the clamping rod 106 to automatically correct minor offsets during descent, reducing manual alignment time and improving clamping efficiency.

[0062] According to one embodiment of the present invention, the clamping rod 106 includes a lead screw, which is rotatably connected to the mounting rod 116, and the pressing part 118 is disposed at the end of the lead screw facing the base 100.

[0063] In one embodiment of this utility model, the top end of the lead screw is connected to the mounting rod 116, and the helical drive of the lead screw can precisely control the height of the clamping part 118 by the number of rotations, ensuring that appropriate clamping force is applied to the rod end bearings of different thicknesses.

[0064] According to one embodiment of the present invention, a handle 122 is provided at the end of the lead screw away from the base 100.

[0065] In one embodiment of this utility model, the handle 122 can be a folding metal crank, which is connected to the top of the lead screw by a pin, and an anti-slip sleeve can also be provided on the handle 122.

[0066] The handle design utilizes leverage to reduce the force required to rotate the leadscrew, thus lowering labor intensity. The anti-slip sleeve increases grip friction, preventing hand slippage and accidents during operation; the folding design minimizes space occupation when not in use and prevents accidental contact. The flexible operation of handle 122 allows for faster leadscrew lifting and lowering compared to using a wrench, reducing clamping and workpiece changing time and improving assembly efficiency.

[0067] According to one embodiment of the present invention, a hinge shaft 124 and a limiting member 126 are provided on the mounting base 114, the mounting rod 116 is hinged to the hinge shaft 124, and the limiting member 126 is used to limit the relative rotation angle between the mounting rod 116 and the mounting base 114.

[0068] In one embodiment of this utility model, the hinge shaft 124 is a stainless steel pin, horizontally fixed to the side of the mounting base 114, and the bottom of the mounting rod 116 is connected to the hinge shaft 124 via a bushing. The limiting member 126 can be a stop bar on the mounting base 114. When the mounting rod 116 is rotated to the vertical working position, the stop bar and the mounting rod 116 are engaged and locked.

[0069] The mounting rod 116 can be rotated to a horizontal position, providing space for the hoisting or removal of the rod end bearing and avoiding interference between the clamping assembly and the workpiece. This is especially suitable for clamping large or heavy bearings. The rigid locking of the limiting member 126 in the vertical working position ensures that the mounting rod 116 is in the same position after each rotation and reset, guaranteeing the alignment accuracy between the clamping rod 106 and the rod end bearing. The rotatable design allows the device to adapt to different loading and unloading methods, reducing the limitation of tooling on the working space and enhancing ease of use.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
