Description

Technical Field

[0001] The utility model belongs to the technical field of differential processing and relates to an online positioning device for a differential housing. Background Art

[0002] When the differential is assembled online, due to the need for the operation of the robot (the robot for flipping the differential case online, the robot for inserting the half-axle gear online), it is necessary to ensure that the differential case is accurately positioned when it is moved to the corresponding workstation. The existing practice is to use the robot on the conveyor line to first complete the positioning of the differential case, and then clamp and flip it or insert the half-axle gear. This greatly increases the cost of the operating robot. In the case of multiple assembly lines, this cost cannot be ignored. Utility Model Content

[0003] The purpose of the utility model is to provide an online positioning device for a differential housing in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to reduce the cost of online positioning of the differential housing.

[0004] The purpose of the utility model can be achieved through the following technical solutions: an online positioning device for a differential housing, characterized in that it includes a conveyor line, an electromagnetic adsorption component arranged on both sides of the conveyor line and a plurality of pallets slidably connected to the conveyor line, two positioning components are arranged on the pallets, and the positioning components include two pull rods slidably connected to the pallets, an iron positioning block is connected between the two pull rods close to the outer side of the pallet, a positioning rod is connected to the inner ends of the two pull rods respectively, the two positioning rods are perpendicular to each other, a tension spring is connected between the pull rods on the same side of the two positioning components, and a rectangular limit frame is formed between the four positioning rods.

[0005] Furthermore, avoidance grooves are provided on the two positioning rods of one positioning assembly, and the two positioning rods of the other positioning assembly are inserted into the avoidance grooves.

[0006] The electromagnetic adsorption component on the conveyor line is a structure of a coil-wound armature. After the coil is energized, it can generate adsorption force, thereby adsorbing the iron positioning block adjacent to it, driving the pull rod to move outward, and the rectangular limit frame formed between the four positioning rods shrinks, thereby driving the differential housing located in the rectangular limit frame to be centered.

[0007] The electromagnetic adsorption component is set at the position corresponding to the working station, and the centering of the differential housing is completed when the control coil is energized. The pallet can continue to move after the coil is powered off. It is not difficult to see that when the coil is energized, not only the centering of the differential housing is completed, but also the position of the pallet on the conveyor line can be limited. This is a low-cost, simple and reliable online positioning method for the differential housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0012] like Figure 1 and Figure 2 The differential housing online positioning device shown includes a conveyor line 1, an electromagnetic adsorption component 2 arranged on both sides of the conveyor line 1 and a plurality of pallets 3 slidably connected to the conveyor line 1, two positioning components are arranged on the pallet 3, the positioning component includes two pull rods 4 slidably connected to the pallet 3, an iron positioning block 5 is connected between the two pull rods 4 close to the outer side of the pallet 3, the inner ends of the two pull rods 4 are respectively connected to a positioning rod 6, the two positioning rods 6 are perpendicular to each other, a tension spring 7 is connected between the pull rods 4 on the same side of the two positioning components, and a rectangular limit frame is formed between the four positioning rods 6.

[0013] The two positioning rods 6 of one positioning assembly are provided with avoidance grooves, and the two positioning rods 6 of the other positioning assembly are inserted into the avoidance grooves.

[0014] The electromagnetic adsorption component 2 on the conveyor line 1 is a structure of a coil-wound armature. After the coil is energized, it can generate an adsorption force, thereby adsorbing the iron positioning block 5 adjacent to it, driving the pull rod 4 to move outward, and the rectangular limit frame formed between the four positioning rods 6 is reduced, thereby driving the differential housing located in the rectangular limit frame to be centered.

[0015] The electromagnetic adsorption component 2 is set at the position corresponding to the working station, and the centering of the differential housing is completed when the control coil is energized. The support plate 3 can continue to move after the coil is powered off. It is not difficult to see that when the coil is energized, not only the centering of the differential housing is completed, but also the position of the support plate 3 on the conveyor line 1 can be limited. This is a low-cost, simple and reliable online positioning method for the differential housing.

[0016] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
