Abstract
Description
Technical Field
[0001] This invention relates to the field of protection for the turnover of precision machined parts for chassis wheels, and in particular to a turnover fixture for the outer half-shaft of a vehicle chassis. Background Technology
[0002] The outer half-shaft, a precision-machined part of the chassis wheel, requires protection for precision-machined areas such as oil seals and bearing positions, and must be free of any scratches or dents. During transport, the outer half-shaft is highly susceptible to scratches and dents due to a lack of effective protective measures, and these damages are often difficult to detect. Once a quality problem occurs, repairs become difficult or even impossible, leading to increased costs and disruptions to production schedules. Summary of the Invention
[0003] To address the aforementioned technical problems, this invention proposes a turnover fixture for the outer half-shaft of a vehicle chassis. This turnover fixture employs a combination of steel and wood structures to achieve safe transport of the outer half-shaft, effectively reducing the construction cost of the turnover fixture while avoiding damage to the outer half-shaft.
[0004] A turnover fixture for the outer half-shaft of a vehicle chassis includes a base frame on which multiple sets of positioning frames are vertically mounted. Each set of positioning frames includes two positioning plates arranged in parallel. The outer half-shaft is vertically limited between the two positioning plates. The positioning plates are made of multiple pieces of wood spliced together. The wood pieces can be slidably placed and removed relative to the base frame.
[0005] As a preferred embodiment of the above technical solution, the timber used to form the positioning plate includes edge timbers on the top and bottom surfaces and intermediate timbers in the middle.
[0006] As a preferred embodiment of the above technical solution, the upper or lower side of the edge timber and the upper and lower sides of the middle timber are arranged in a straight line with large and small circular arc grooves, which are staggered, and an annular groove is provided in the large circular arc groove along its arc direction.
[0007] As a preferred embodiment of the above technical solution, the large and small circular arc grooves on the upper and lower sides of the middle timber are provided in a one-to-one correspondence.
[0008] As a preferred embodiment of the above technical solution, the basic frame is welded from channel steel.
[0009] As a preferred embodiment of the above technical solution, the timber is picked up and placed by sliding along the gap between the upper and lower flanges of the channel steel.
[0010] As a preferred embodiment of the above technical solution, hooks are symmetrically fixed to the bottom side of the basic frame.
[0011] The beneficial effects of this invention are as follows:
[0012] 1. The combination of steel and wood structure is used to achieve safe transfer of the outer half shaft. The implementation cost is low, the transfer is convenient, and the batch transfer of turnover sections can be realized.
[0013] 2. The structure is simple, stable and reliable, which can effectively reduce the risk of collision damage during its turnover and is suitable for widespread application. Attached Figure Description

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0019] like Figures 1 to 3 The present invention relates to a turnover fixture for an outer half-shaft of a vehicle chassis, comprising a base frame 1, on which multiple sets of positioning frames are vertically mounted. Each set of positioning frames includes two positioning plates 2 arranged in parallel. The outer half-shaft 9 is vertically limited between the two positioning plates 2. The positioning plates 2 are made of multiple pieces of wood spliced together. The wood can be slidably placed and removed relative to the base frame 1.
[0020] In this embodiment, the wooden blocks used to form the positioning plate 2 include edge wooden blocks 3 on the top and bottom surfaces and middle wooden blocks 4 in the middle.
[0021] In this embodiment, the upper or lower side of the edge timber 3 and the upper and lower sides of the middle timber 4 are arranged in a straight line with large circular arc grooves 5 and small circular arc grooves 6. The large circular arc grooves 5 and small circular arc grooves 6 are staggered. The large circular arc groove 5 is provided with an annular groove 7 along its arc direction.
[0022] In this embodiment, the large circular arc grooves 5 and small circular arc grooves 6 on the upper and lower sides of the middle wooden block 4 are provided in a one-to-one correspondence.
[0023] In this embodiment, the basic frame 1 is welded from channel steel.
[0024] In this embodiment, the timber is picked up and placed by sliding along the gap between the upper and lower flanges of the channel steel.
[0025] In this embodiment, hooks 8 are symmetrically fixed on the bottom side of the base frame 1.
[0026] When using this rotating tool to transport the outer half-shaft 9, the outer half-shaft 9 is placed in a layer-by-layer positioning manner, as follows: First, the bottom layer of edge timber 3 is placed. The large arc grooves 5 and small arc grooves 6 of the bottom layer edge timber 3 on both sides of the same positioning frame are set one-to-one. The flange of the large end of the outer half-shaft 9 is engaged in the annular groove 7. At this time, the oil seal and bearing position of the large end of the outer half-shaft 9 near the flange do not contact the timber to avoid damage. The small end rests on the small arc groove 6 of another set of bottom layer edge timber 3. Then, the middle timber 4 is placed layer by layer. While positioning the next layer of outer half-shaft 9, the next layer of outer half-shaft 9 is placed. Finally, the top layer of edge timber 3 is used for positioning. The hook 8 is set to facilitate the overall transportation of the basic frame 1.
[0027] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
