Description

Technical Field

[0001] This utility model relates to the field of fixtures for assembling steering systems, specifically to a fixture for marking the angle of the universal joint of the steering linkage. Background Technology

[0002] In the assembly of steering linkages and universal joints, traditional methods lack dedicated angle marking fixtures, relying solely on manual experience to position the universal joints. This not only makes it difficult to ensure the accuracy of the universal joint angle markings, leading to deviations in the angles of subsequent assembly and affecting the overall performance of the steering system; but also, ordinary fixtures lack protective structures during assembly, easily scratching the surfaces of the steering linkages and universal joints. Furthermore, traditional fixtures are either structurally unstable and prone to deformation, or heavy and inconvenient for operators to handle, causing numerous inconveniences in the actual assembly work.

[0003] To address this, a clamp for marking the universal joint angle of the steering linkage is proposed. Utility Model Content

[0004] The present invention aims to solve the problems mentioned in the background art by providing a clamp for marking the angle of the universal joint of the steering connecting rod.

[0005] The specific technical solution is as follows:

[0006] A clamp for marking the angle of a steering linkage universal joint includes: a clamp body for marking the angle of the steering linkage universal joint, the clamp body being a square tubular hollow structure with open ends, one end of the clamp body having a locking slot for locking the universal joint and a limiting groove for limiting the bolts on the universal joint, and the other end of the clamp body having a scribing groove for marking the angle of the steering linkage universal joint.

[0007] As a preferred embodiment of this utility model, the shape of the bayonet is adapted to the outer periphery of the universal joint, and relying on the square tubular structure of the clamp body, the radial limit of the universal joint is more stable after it is inserted into the bayonet, and it is not easy to deviate.

[0008] As a preferred embodiment of this utility model, the limiting groove is opened along the radial direction of the clamp body, and the width of the limiting groove is adapted to the diameter of the bolt on the universal joint. With the support of the square tube wall of the clamp body, the circumferential and axial limiting of the bolt is more reliable.

[0009] As a preferred embodiment of this utility model, the scribing groove is an elongated groove extending along the axial direction of the fixture body. Based on the flat side of the square tubular shape of the fixture body, the groove opening is more regular, which facilitates the smooth operation of the scribing tool.

[0010] As a preferred embodiment of this utility model, the clamp body is made of aluminum alloy. The square tubular structure combined with the properties of aluminum alloy not only ensures structural strength to resist deformation during use, but also achieves lightweight design, making it convenient for operators to handle by hand.

[0011] As a preferred embodiment of this utility model, the axial length of the clamp body matches the length of the assembly formed by assembling the steering connecting rod and a universal joint. With the regular axial dimensions of the square tubular shape, the universal joint can be fully inserted into the bayonet and the bolt can be accurately embedded in the limiting groove.

[0012] As a preferred embodiment of this utility model, the number of the bayonet is two, and the two bayonet are symmetrically arranged at one end of the clamp body. Combined with the symmetrical structure of the square tube of the clamp body, they respectively clamp the two connecting ears of the universal joint, so that the universal joint is subjected to more balanced force.

[0013] As a preferred embodiment of this utility model, the depth of the limiting groove is not less than the radius of the bolt, and the thickness of the square tube wall of the clamp body ensures that there is no axial movement after the bolt is embedded.

[0014] As a preferred embodiment of this utility model, the groove width of the scribing groove is -mm. Based on the flatness of the square tubular side of the fixture body, the groove width is easier to process accurately, thereby adapting to the width of the pen tip or scribing head of common scribing tools.

[0015] As a preferred embodiment of this utility model, the inner and outer surfaces of the clamp body are provided with rubber protective layers. Utilizing the regularity of the square structure of the clamp body, the rubber protective layers adhere more evenly, which can better prevent scratches on the steering connecting rod and universal joint.

[0016] As a preferred embodiment of this utility model, the inner corners of the square tube of the clamp body are provided with a rounded corner structure. The rounded corners eliminate stress concentration at the inner corners of the square tube and improve the structural durability of the clamp body.

[0017] This utility model has the following beneficial effects:

[0018] The present invention provides a clamp for marking the angle of a universal joint on a steering linkage. The clamp body adopts a square tubular hollow structure, which is regular in structure and can provide stable support. By using a bayonet to hold the universal joint and a limiting groove to limit the bolts on the universal joint, the rotation of the universal joint can be effectively restricted, and the universal joint can be accurately positioned. In addition, the scribing groove at the other end of the clamp body facilitates the marking of the universal joint angle marking line 2 on the steering linkage, so that the other end of the universal joint can be assembled according to the marked angle marking line, ensuring the accuracy of the universal joint angle marking line and subsequent assembly.

[0030] Example

[0031] The clamp provided in this embodiment for marking the universal joint angle of the steering linkage is, for example... Figures 1-4 As shown, it includes: a clamp body 1 for marking the angle of the universal joint 201 of the steering connecting rod 2. The clamp body 1 is a square tubular hollow structure with open ends. One end of the clamp body 1 is provided with a bayonet 101 for locking the universal joint 201 and a limiting groove 102 for limiting the bolt 202 on the universal joint 201. The other end of the clamp body 1 is provided with a scribing groove 103 for marking the angle of the universal joint of the steering connecting rod 2.

[0032] In this design, the fixture body 1 adopts a square tubular hollow structure, which is regular in structure and can provide stable support. The bayonet 101 is used to hold the universal joint 201, and the limiting groove 102 limits the bolt 202 on the universal joint 201, which can effectively restrict the rotation of the universal joint 201 and achieve precise positioning of the universal joint 201. In addition, the scribing groove 103 at the other end of the fixture body 1 provides convenience for marking the universal joint angle marking line 203 on the steering connecting rod 2, so that the other end of the universal joint can be assembled according to the marked angle marking line 203, ensuring the accuracy of the universal joint angle marking line 203 and subsequent assembly.

[0033] Specifically, in this embodiment, the shape of the bayonet 101 is adapted to the outer periphery of the universal joint 201, and relying on the square tubular structure of the clamp body 1, the radial positioning of the universal joint 201 is more stable after it is engaged in the bayonet 101, making it less prone to deflection. The regularity of the square tubular structure, combined with the fit between the bayonet 101 and the contour of the universal joint 201, enhances the stability of the radial positioning of the universal joint 201, prevents radial displacement of the universal joint 201 during angle marking, and ensures positioning accuracy.

[0034] Specifically, in this embodiment, the limiting groove 102 is opened radially along the fixture body 1, and the groove width of the limiting groove 102 is adapted to the diameter of the bolt 202 on the universal joint 201. With the support of the square tube wall of the fixture body 1, the circumferential and axial limiting of the bolt 202 is more reliable. The square tube wall provides stable structural support for the limiting groove 102, effectively limiting the circumferential rotation and axial movement of the bolt 202 after it is inserted, further ensuring the accurate position of the universal joint 201 when the angle marking line 203 is marked, and avoiding motion interference.

[0035] Specifically, in this embodiment, the scribing groove 103 is an elongated groove extending along the axial direction of the fixture body 1. Based on the flat, square tubular side surface of the fixture body 1, the groove opening of the scribing groove 103 is more regular, facilitating the smooth operation of the scribing tool. The flat, square tubular side surface makes the groove opening more regular after processing, providing a stable operating reference for the scribing tool, making the angle marking line 203 engraved on the steering connecting rod 2 more accurate and smooth, and improving the convenience and accuracy of angle marking.

[0036] Specifically, in this embodiment, the fixture body 1 is made of aluminum alloy. The square tubular structure, combined with the properties of aluminum alloy, ensures structural strength to resist deformation during use while achieving lightweight design, making it easy for operators to hold and work with. The combination of aluminum alloy material and square tubular structure balances structural rigidity, torsional resistance, bending deformation resistance, and lightweight design, extending the service life of the fixture while improving ease of operation.

[0037] Specifically, in this embodiment, the axial length of the fixture body 1 matches the length of the assembly formed by assembling the steering connecting rod 2 and a universal joint 201. Thanks to the regular axial dimensions of the square tubular structure, the universal joint 201 can be fully engaged in the bayonet 101, and the bolt 202 can be accurately embedded in the limiting groove 102. The regular axial dimensions of the square tubular structure and the length-matching design ensure that the universal joint 201 and bolt 202 are fully positioned within the fixture, avoiding positioning failure due to length deviation. This ensures the reliability of the preconditions for angle marking, guaranteeing that the angle marking line 203 can be accurately engraved on the other end of the steering connecting rod 2.

[0038] Specifically, in this embodiment, there are two bayonets 101, which are symmetrically arranged at one end of the fixture body 1. Combined with the symmetrical structure of the square tube of the fixture body 1, they respectively hold the two connecting ears of the universal joint 201, making the force on the universal joint 201 more balanced. The symmetrical structure of the square tube provides a symmetrical machining and installation reference for the two bayonets 101. The symmetrical holding of the connecting ears of the universal joint 201 by the two bayonets ensures that the universal joint 201 is subjected to balanced force within the fixture, further improving positioning stability and preventing displacement caused by unilateral force.

[0039] Specifically, in this embodiment, the depth of the limiting groove 102 is not less than the radius of the bolt 202. Relying on the thickness of the square tube wall of the fixture body 1, it ensures that the bolt 202 does not move axially after being inserted. The square tube wall has sufficient thickness to design a limiting groove 102 that meets the depth requirements, allowing the bolt 202 to be fully inserted into the groove, firmly restricting its axial movement and preventing axial movement of the bolt 202 during the marking of the angle marking line 203, thus ensuring the stability of the universal joint 201.

[0040] Specifically, in this embodiment, the width of the scribing groove 103 is 2-5mm. Based on the flatness of the square tubular side of the fixture body 1, the groove width is easier to process precisely, thus adapting to the width of the pen tip or scribing head of common scribing tools. The flatness of the square tubular side facilitates the precise processing of the groove width of the scribing groove 103, enabling the groove width to match a variety of commonly used scribing tools well, improving the versatility of the fixture, and facilitating the marking of angle marking lines 203 in different scenarios.

[0041] Specifically, in this embodiment, both the inner and outer surfaces of the clamp body 1 are provided with a rubber protective layer. Utilizing the regularity of the square structure of the clamp body 1, the rubber protective layer adheres more evenly, better preventing scratches on the steering connecting rod 2 and the universal joint 201. The regularity of the square structure ensures that the rubber protective layer adheres more evenly and without wrinkles. When the clamp contacts the steering connecting rod 2 and the universal joint 201, it provides comprehensive and even cushioning protection, effectively preventing scratches on the component surfaces and protecting the component quality.

[0042] Specifically, in this embodiment, the inner corners of the square tubular part of the clamp body 1 are provided with rounded corner structures. By rounding the corners, stress concentration at the inner corners of the square tubular part is eliminated, thereby improving the structural durability of the clamp body 1. The rounded corner design of the inner corners of the square tubular part avoids stress concentration at the corners, reduces the risk of cracks in the clamp due to long-term use or stress, extends the service life of the clamp, and ensures the structural reliability during long-term use.

[0043] In summary, the clamp for marking the universal joint angle of the steering linkage provided in this embodiment has the following advantages:

[0044] 1. Positioning accuracy: Relying on the stable support of the square tubular structure of the fixture body 1, and with the compatibility of the bayonet 101 with the contour of the universal joint 201 and the compatibility of the limiting groove 102 with the bolt 202, it can effectively restrict the axial, radial and circumferential movement of the universal joint 201, avoid the universal joint 201 from shifting when the angle marking line 203 is marked, provide a precise angle reference for the subsequent universal joint assembly, and ensure the assembly performance of the steering system.

[0045] 2. Ease of operation: The scribing groove 103 utilizes the flat side of the square tubular shape of the fixture body 1, and the groove opening is regular, which facilitates the smooth operation of the scribing tool and makes the angle marking line 203 smooth and accurate. At the same time, the combination of aluminum alloy material and square tubular structure takes into account the structural strength and lightweight of the fixture body 1, which makes it convenient for operators to operate by hand and reduces the difficulty of operation.

[0046] 3. Component protection: The rubber protective layer on the inner and outer surfaces of the clamp body 1 can be evenly fitted due to the regularity of the square structure. When the clamp comes into contact with the steering connecting rod 2 and the universal joint 201, it can play a buffering role, effectively preventing the surface of the components from being scratched and protecting the appearance and quality of the components.

[0047] 4. Structural durability: The rounded corners of the square tubular inner corners of the fixture body 1 can eliminate stress concentration at the inner corners and reduce the risk of cracks when the fixture is used for a long time or under stress; at the same time, the use of aluminum alloy material improves the deformation resistance of the fixture body 1 and extends the overall service life of the fixture.

[0048] Working principle

[0049] The clamp body 1 adopts a square tubular hollow structure with openings at both ends, which provides regular and stable support for the entire clamp. In use, the universal joint 201 is aligned with the bayonet 101 at one end of the clamp body 1. Since the shape of the bayonet 101 matches the outer contour of the universal joint 201, the bayonet 101 can lock the universal joint 201 and restrict its rotation. At the same time, the bolt 202 on the universal joint 201 will be embedded in the limiting groove 102 at the same end of the clamp body 1. The groove width of the limiting groove 102 matches the diameter of the bolt 202. With the stable support of the square tube wall of the clamp body 1, the rotation of the bolt 202 can be effectively restricted, thereby preventing the universal joint 201 and the steering connecting rod 2 from rotating, achieving precise positioning of the universal joint 201.

[0050] The scribing groove 103 at the other end of the fixture body 1 is an elongated groove extending along the axial direction. Thanks to the flat, square tubular side of the fixture body 1, the groove opening of the scribing groove 103 is more regular, allowing scribing tools to pass smoothly and accurately mark the universal joint angle marking line 203 at the other end of the steering connecting rod 2. Furthermore, the fixture body 1 is made of aluminum alloy, combined with a square tubular structure, ensuring sufficient structural strength to resist deformation during use while also achieving lightweight design. The rubber protective layer on the inner and outer surfaces of the fixture body 1 adheres evenly due to the regularity of the square structure, preventing direct contact and scratches between the fixture and the steering connecting rod 2 and universal joint 201. The rounded corners of the square tubular inner corners of the fixture body 1 eliminate stress concentration at the inner corners, improving the structural durability of the fixture body 1.

[0051] How to use

[0052] 1. Positioning and installation: Align the assembled steering connecting rod 2 and a universal joint 201 with the square tubular hollow structure of the fixture body 1, and insert the universal joint 201 into the bayonet 101 at one end of the fixture body 1, ensuring that the bolt 202 on the universal joint 201 is accurately embedded in the limiting groove 102 at the same end. At this time, the universal joint 201 cannot rotate.

[0053] 2. Marking angle lines: Hold a marking tool (such as a marking needle or marking pen) and slowly and steadily mark the universal joint angle marking line 203 on the steering connecting rod 2 along the marking groove 103 at the other end of the fixture body 1.

[0054] 3. Remove the clamp: After the angle marking line 203 is marked, remove the clamp body 1 from the assembly structure of the steering connecting rod 2 and the universal joint 201.

[0055] 3. Subsequent assembly: According to the angle marking line 203 already engraved on the steering connecting rod 2, assemble the universal joint at the other end to ensure that its assembly angle is consistent with the marked angle.

Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
