Abstract
Description
Technical Field
[0001] This utility model relates to the field of components, specifically to a transport crossbar device. Background Technology
[0002] Transport crossbars are used in the transportation of automotive parts. They generally need to be bent on both sides of the main body and then knurled. Currently, most methods are to knurl first and then bend, but this final knurling will be off-center in time and will not achieve the desired effect. Utility Model Content
[0003] The problem this utility model aims to solve is to provide a transport crossbar device for fixing other components to the crossbar, addressing the aforementioned deficiencies in the existing technology.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a transport crossbar device, comprising a transport crossbar body, the transport crossbar body comprising a straight rod and knurled arc-shaped segments extending from both ends of the straight rod and connecting ends extending outward from the knurled arc-shaped segments, a first sleeve and a second sleeve both sleeved on the transport crossbar body, the first sleeve sleeved on the second sleeve, the first sleeve and the second sleeve both being spliced together in half, the second sleeve having a positioning blind hole, the first sleeve having a through hole, when the positioning pin passes through the through hole and inserts into the blind hole, the farthest ends of the first sleeve and the second sleeve respectively contact the knurled arc-shaped segments on both sides.
[0005] Furthermore, a third sleeve is fitted onto the connecting end, and the knurled arc segment is located precisely between the third sleeve and the first sleeve or the second sleeve.
[0006] Furthermore, the third sleeve is provided with a through hole, and the first sleeve and the second sleeve are respectively provided with a first sensing point and a second sensing point at the end corresponding to the third sleeve. When the through hole corresponds exactly to the first sensing point or the second sensing point, the knurled arc segment reaches the bending requirement.
[0007] Compared with the prior art, the present invention has the following advantages: The present invention adjusts the relative positions of the first sleeve and the second sleeve so that the two ends of the first sleeve and the second sleeve are exactly aligned with the knurled arc segment. Then, the pin passes through the through hole and is inserted into the blind hole, thereby facilitating the knurling process and avoiding affecting other parts.
[0008] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of a transport crossbar device. Detailed Implementation
[0010] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments:
[0011] This utility model proposes a transport crossbar device, including a transport crossbar body 1. The transport crossbar body 1 includes a straight rod, knurled arc-shaped segments 2 extending from both ends of the straight rod, and connecting ends 3 extending outward from the knurled arc-shaped segments 2. A first sleeve 4 and a second sleeve 5 are both fitted onto the transport crossbar body 1, with the first sleeve 4 fitted onto the second sleeve 5. Both the first sleeve 4 and the second sleeve 5 are formed by splicing two halves together. The second sleeve 5 has a positioning blind hole 6, and the first sleeve 4 has a through hole 8. When the positioning pin 7 passes through the through hole 8 and is inserted into the blind hole 6, the farthest ends of the first sleeve 4 and the second sleeve 5 respectively contact the knurled arc-shaped segments 2 on both sides. The sleeve 4 includes a first through hole and a second through hole connected in sequence. The inner diameter of the first through hole is equal to the outer diameter of the straight rod, and the inner diameter of the second through hole is equal to the outer diameter of the second sleeve 5. The second sleeve 4 includes a first semi-annular retainer and a second semi-annular retainer. The first semi-annular retainer and the second semi-annular retainer have side ears respectively provided with first mounting holes for bolt installation and locking. The first semi-annular retainer and the second semi-annular retainer are combined to form the first sleeve 4. The second sleeve 5 includes a third semi-annular retainer and a fourth semi-annular retainer. The third semi-annular retainer and the fourth semi-annular retainer are provided with side ears for docking. The side ears are provided with second mounting holes and are fixed with existing bolts to form the second sleeve 5, thereby facilitating disassembly.
[0012] A third sleeve 11 is fitted onto the connecting end 3, and the knurled arc segment 2 is located exactly between the third sleeve 11 and the first sleeve 4 or the second sleeve 5; the third sleeve 11 has a third through hole 9, and the inner diameter of the third through hole 9 is equal to the outer diameter of the connecting end 3.
[0013] The third sleeve 11 is provided with a through hole 10. The first sleeve 4 and the second sleeve 5 are respectively provided with a first sensing point and a second sensing point at the end corresponding to the third sleeve 11. When the through hole 10 corresponds exactly to the first sensing point or the second sensing point, the knurled arc segment 2 reaches the bending requirement. After fixing the third sleeve 11, the first sleeve 4 and the second sleeve 5 with the existing clamp, the knurled arc segment 2 is first bent until the through hole 10 corresponds exactly to the first sensing point or the second sensing point, which reaches the bending condition. Then, the required knurling is made between the third sleeve 11 and the first sleeve 4 and / or the second sleeve 5.
[0014] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
