Description

Technical Field

[0001] The utility model relates to the technical field of synchronizer production equipment, in particular to a material tray for automobile synchronizer production. Background Art

[0002] The synchronizer is a key component in the automobile gearbox. It is used to synchronize the speed of the two newly meshed gears when shifting gears to avoid tooth jamming. During the production and transportation process, pallets are needed for batch transportation. In the prior art, a Chinese patent with publication number CN109625535A proposed a solution, which sets stepped holes on the pallet to solve the possible locking situation between the gear rings. However, the solution requires a significant increase in the thickness of the pallet, which increases the mass and makes a lot of materials unusable and wasteful. Summary of the invention

[0003] The utility model proposes a material tray for automobile synchronizer production, comprising a base plate, wherein a plurality of support components are arranged on the base plate, wherein the support components include three support units, and the three support units are used to support the outer wall ring groove of the coupling sleeve of the synchronizer; the support unit includes a protruding portion, a first connecting member, a second connecting member, and a pin; the protruding portion is arranged on the base plate, and the two ends of the first connecting member are respectively hinged to the protruding portion and one end of the second connecting member; the other end of the second connecting member is used to insert into and abut against the outer wall ring groove of the coupling sleeve of the synchronizer; the pin is used to penetrate the first connecting member and be inserted into the base plate.

[0004] The utility model is further configured as follows: a supporting curved surface is provided at the end of the second connecting member away from the first connecting member, and the supporting curved surface is used to fit the outer wall ring groove of the coupling sleeve of the synchronizer.

[0005] The utility model is further configured as follows: the bottom plate and the second connecting member are respectively provided with a positioning hole and a pin hole, and the pin is used to penetrate the pin hole and be inserted into the positioning hole.

[0006] The beneficial effects of the utility model are:

[0007] The three support units can provide constraints on the synchronizer within the horizontal range, and also limit the height position of the synchronizer's coupling sleeve, so that the synchronizer cannot move in any direction without the second connecting piece releasing the restriction, and prevent the coupling sleeve from falling and hitting the locking ring or causing locking.

[0012] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0013] See also Figure 1-3 The utility model proposes a material pallet for the production of automobile synchronizers 6, including a bottom plate 1. A plurality of support components are arranged on the bottom plate 1. Each support component is used to support a synchronizer 6. The area of ​​the bottom plate 1 and the number of support components can be adjusted based on actual needs. For the needs of transportation, a lifting ring can be arranged on the bottom plate 1, or a universal wheel can be arranged at the bottom of the bottom plate 1, or a square steel pipe for use with a forklift can be arranged at the bottom of the bottom plate 1. The scheme is not unique, so the relevant structure is not specifically shown in the attached drawings.

[0014] The support assembly includes three support units, which are distributed at three corner points of an equilateral triangle and are used to provide support to the outer wall ring groove of the engagement sleeve of the synchronizer 6 from different directions.

[0015] The support unit includes a protrusion 2, a first connecting member, a second connecting member and a pin 5. The protrusion 2 is welded to the upper surface of the base plate 1, and the two ends of the first connecting member are respectively hinged to the protrusion 2 and one end of the second connecting member, and the axis direction of the hinge is horizontal. The other end of the second connecting member is used to insert and abut against the outer wall ring groove of the coupling sleeve of the synchronizer 6, and the end is provided with a supporting curved surface 42, which can fit the groove bottom surface of the outer wall ring groove to avoid damage to the surface of the synchronizer 6.

[0016] However, the second connecting member is currently unstable, so it is necessary to use the pin 5. The bottom plate 1 and the second connecting member are respectively provided with a positioning hole 11 and a pin hole 41, and the pin 5 is used to penetrate the pin hole 41 and be inserted into the positioning hole 11, and realize the constraint and fixation of the second connecting member. Only by pulling out the pin 5 can the constraint of the second connecting member be released.

[0017] When the second connecting member is fixed, the three supporting units can provide constraints on the synchronizer 6 within the horizontal range, and also limit the height position of the coupling sleeve of the synchronizer 6, so that the synchronizer 6 cannot move in any direction without releasing the restriction of the second connecting member, and prevent the coupling sleeve from falling and hitting the locking ring or causing locking, etc.

[0018] In summary, this solution provides more adequate constraints on the synchronizer 6 and avoids material waste caused by excessive use of materials.
