Description

Technical Field

[0001] This utility model relates to the field of two-wheeled vehicle assembly tooling technology, and in particular to an installation tooling that is compatible with handlebars of multiple specifications and directions. Background Technology

[0002] Traditional electric bicycle / electric motorcycle handlebars are assembled by fixing them to the handlebar stem via handlebar fixing blocks and standard parts.

[0003] In the existing technology, this installation method has many tolerances in the mating parts, which causes the center of the front wheel and the center of the handlebars to be not on the same center line during the rider's ride, affecting the riding experience and safety. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides an installation fixture that is compatible with multiple specifications and directions of the handle, which uses an upper pressure structure to coaxially fix the handle riser.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An installation fixture adaptable to multi-specification directional handles includes a base plate, on which a positioning recess and a quick clamp are provided. The quick clamp applies a downward limiting force vertically toward the positioning recess.

[0007] The base plate is also equipped with a cylinder, and the cylinder's push rod is perpendicular to the line connecting the quick clamp and the positioning recess.

[0008] The bottom end of the handlebar stem to be assembled is limited by a positioning recess, the top end of the handlebar stem to be assembled is limited by a quick clamp, and the cylinder push rod is coaxial with the fixing hole on the handlebar stem to be assembled.

[0009] As a further improvement to the above technical solution:

[0010] A support rod is provided on the substrate, and a quick clamp is installed on the support rod; the support rod is provided with a positioning recess to avoid obstruction.

[0011] The support rod includes a support section perpendicular to the substrate, an extension section located at the top of the support section and bent upward toward the positioning recess, and a quick clamp located on the extension section.

[0012] The quick clamp has a compensating rod segment connected to one of its pressing ends, which applies pressure to the riser tube to be assembled.

[0013] The compensating rod segment passes through the support rod and points towards the handlebar stem to be assembled. The compensating rod segment is pushed vertically back and forth by the quick clamp.

[0014] The positioning recess includes:

[0015] The receiving portion is a recessed groove or through groove on the substrate.

[0016] The positioning part is a recessed groove or through groove on the substrate. The positioning part is equipped with a positioning element, part of which falls in the positioning part and part of which falls in the fixing hole of the handlebar tube to be assembled.

[0017] The positioning part is located on the extension line of the center line of the receiving part and is coplanar with the fixing hole of the handlebar to be assembled.

[0018] The positioning element and the positioning part are independent of each other.

[0019] The positioning recess adopts a stepped countersunk hole structure.

[0020] The angle between the center of the cylinder and the support rod and the center of the stem tube to be assembled is less than 180°.

[0021] The beneficial effects of this utility model are as follows:

[0022] This invention improves upon existing handlebar stem assembly methods by using a base plate and quick clamps to vertically limit the handlebar stem, and then using a cylinder to press the fixing block into the fixing hole.

[0023] The challenge in the tooling design of this application lies in ensuring that the end of the push rod aligns precisely with the fixing hole during cylinder pushing. This application fixes the position of the pneumatic module to reduce influencing factors during alignment. A positioning recess is provided on the base plate to accommodate the handlebar stem to be assembled. The end of the handlebar stem with the fixing hole is embedded in the positioning recess. However, there may still be a relative deviation between the fixing hole and the end of the push rod. Therefore, this application proposes an optimized solution to replace manual rotation for handlebar alignment. A calibration groove is provided on the base plate, and a calibration component is matched to the groove. One end of the calibration component falls into the groove, and the other end fits into the fixing hole, ensuring that the handlebar stem is in an assembleable position. Then, the quick-clamping clamp is pressed, completely limiting the handlebar stem. Subsequently, stable and precisely directional pressure is output by the cylinder to achieve high-precision assembly.

[0024] The tooling in this application also has the advantage of easy installation: the riser fixing structure can be seamlessly connected with the existing direction of electric bicycles / electric motorcycles. Attached Figure Description

[0033] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0034] like Figures 1-4 As shown, the mounting fixture for multi-specification directional handles in this embodiment includes a base plate 1. The base plate 1 has a positioning recess 2 and a quick clamp 5. The downward limiting force applied by the quick clamp 5 points vertically towards the positioning recess 2.

[0035] The base plate 1 is also provided with a cylinder 6, and the push rod of the cylinder 6 is perpendicular to the line connecting the quick clamp 5 and the positioning recess 2.

[0036] The bottom end of the handlebar stem to be assembled is limited by the positioning recess 2, the top end of the handlebar stem to be assembled is limited by the quick clamp 5, and the push rod of the cylinder 6 is coaxial with the fixing hole on the handlebar stem to be assembled.

[0037] A support rod 4 is provided on the substrate 1, and a quick clamp 5 is installed on the support rod 4; the support rod 4 is provided to avoid the positioning recess 2.

[0038] The support rod 4 includes a support section 401 perpendicular to the substrate 1, an extension section 402 located at the top of the support section 401 and bent upward toward the positioning recess 2, and a quick clamp 5 located on the extension section 402.

[0039] The quick clamp 5 has a compensating rod segment 501 connected to one of its pressing ends. The compensating rod segment 501 applies pressure to the riser pipe to be assembled.

[0040] The compensating rod segment 501 passes through the support rod 4 and points towards the handlebar stem to be assembled. The compensating rod segment 501 is pushed vertically and reciprocally by the quick clamp 5.

[0041] Positioning recess 2 includes:

[0042] The receiving part 201 is a recessed groove or through groove on the substrate 1.

[0043] The positioning part 202 is a recess or through groove on the substrate 1. The positioning part 202 is equipped with a positioning member 3. Part of the positioning member 3 falls in the positioning part 202 and part falls in the fixing hole of the handlebar tube to be assembled.

[0044] The positioning part 202 is located on the extension line of the center line of the receiving part 201 and is coplanar with the fixing hole of the handlebar to be assembled.

[0045] The positioning element 3 and the positioning part 202 are independent of each other.

[0046] The positioning recess 2 adopts a stepped countersunk hole structure.

[0047] The central angle between cylinder 6 and support rod 4 corresponding to the handlebar stem to be assembled is less than 180°. The purpose of this design is to allow the operator to see the mounting hole of the handlebar stem at a greater angle, thus facilitating the operator's view.

[0048] The specific structure and working principle of this application are as follows:

[0049] Conventional handlebar stem fixtures are often complex in structure, including bottom and top clamping components, due to the need to limit the axial and circumferential movement of the handlebar stem. This application provides a simpler assembly fixture applicable to various sizes. A stepped hole is created on the base plate 1 as a positioning recess 2, and the end of the handlebar stem to be assembled rests in the positioning recess 2. Handlebar stems of different diameters are limited by the stepped hole corresponding to their diameter.

[0050] A support rod 4 is also provided on the substrate 1. The support section 401 of the support rod 4 extends vertically from the substrate 1. The top of the support section 401 is bent to form an extension section 402. A quick clamp 5 is installed on the extension section 402. The quick clamp 5 adopts a specification in which the push rod extends vertically downward when it is turned. In order to accommodate different specifications of handlebar stem tubes, a hole is made in the extension section 402. The turning end of the quick clamp 5 drives a compensation rod section 501, which extends downward through the extension section 402. In this way, when the bottom end of the handlebar stem tube to be assembled is placed in the positioning recess 2, the top end of the handlebar stem tube to be assembled can be limited by turning the quick clamp 5. Since the end of the compensation rod section 501 facing the handlebar stem tube in this embodiment is parallel to the plane of the substrate 1, the quick clamp 5 can also help straighten the handlebar stem tube to be assembled when it is pressed, ensuring that the handlebar stem tube to be assembled is perpendicular to the substrate 1.

[0051] One of the key improvements in this application lies in how to ensure that the cylinder 6 push rod on the substrate 1 is precisely aligned with the fixing hole of the handlebar stem to be assembled. In this embodiment, the aforementioned stepped hole serves as a receiving portion 201, and a groove is provided at the end of the receiving portion 201 away from the cylinder 6 as a positioning portion 202. The positioning portion 202 is located at the centerline of the receiving portion 201, that is, the positioning portion 202 is also directly opposite the fixing hole. A Z-shaped positioning member 3 as shown in the figure is then configured. When placing the handlebar stem to be assembled, the bottom end of the positioning member 3 is placed in the positioning portion 202, and the positioning member 3 is pushed forward until the top end of the positioning member 3 passes through the fixing hole. At this time, it can be ensured that the circumferential position of the handlebar stem to be assembled is also limited. The cylinder 6 then pushes the locking block into the fixing hole, which can ensure the coaxial accuracy of the locking block and the fixing hole.

[0052] This application is easy to assemble, applicable to products of various specifications, has a simpler structure, and reduces production costs.
