Detailed Description
The structural features of the present invention are further described below with reference to the drawings and the specific embodiments.
As shown in fig. 1 to 4, an assembling and welding device based on powder metallurgy products comprises an upper die 2, a lower die 3 and an elbow clamp assembly 1 for controlling the opening and closing of the dies; the upper die 2 and the lower die 3 are positioned and fixed through pins 6 and pin holes; the lower side of the upper die 2 is provided with a pressing component 5 corresponding to a product to be welded; the pressing assembly 5 comprises a supporting assembly, a pressing claw 53 and a pressing sheet 54; the upper end part of the pressing claw 43 is inserted into a sliding hole matched with the pressing claw 43 arranged on the supporting frame, and a first spring 51 is arranged in the sliding hole; the pressing sheet 54 is movably connected with a corresponding pin hole on the support frame through a sliding pin, and the sliding pin is sleeved with a second spring 52; the lower die 3 is provided with products to be welded, every two products to be welded are arranged in the limiting mechanism in a group of parallel, and each group of products is provided with a material belt and an elastic sheet matched with the products; the elastic sheet 8 is in weak connection with the material belt; the upper die is pressed down on the elastic sheet 8, so that the product 9 is positioned in the Z-axis direction.
The elastic sheet 8 and the material belt are of an integral structure, and the material belt comprises a plurality of elastic sheets which are uniformly arranged; the elastic sheet 8 is of a symmetrical structure and comprises an elastic sheet main body and V-shaped clamping grooves arranged at two ends of the elastic main body, and one side edge of each V-shaped clamping groove is in the same plane with the elastic sheet main body; the distance between the two V-shaped clamping grooves corresponds to two welding products respectively. The elastic sheet main body and the material belt are on the same plane.
The weak connection is point connection, line connection or tooth hole connection; so that the elastic sheet 8 and the material belt are broken or separated at the connecting point.
The belt material is provided with positioning holes corresponding to the products and used for limiting the products to move on X and Y axes. Thereby ensuring the dimension of the two products in the X, Y direction.
A compression spring 7 is arranged between the lower die 3 and the base of the die to reduce vibration.
And material returning plates 4 are arranged on two sides below the lower die to receive the material strips.
Firstly, in order to facilitate assembly, firstly, the elastic sheets are required to be orderly arranged, every ten elastic sheets are arranged in one group, a material carrying point, namely a V-shaped clamping groove, is arranged between each elastic sheet and the material belt, so that the material belt and the elastic sheets are convenient to separate, and positioning holes are formed.
Then, two products are required to be combined together, and the hole sites on the MIM piece and the elastic piece material belt can be used for positioning in the X and Y directions, so that the sizes of the two products in the X, Y directions are ensured.
Again, to follow the principle of three-point positioning of one spatial coordinate, we also need to position the two products combined together in the Z-direction, namely: and (5) pressing and positioning the product in the Z direction through an upper die and pressing combination.
Finally, laser spot welding is performed by a laser welding device. After welding, the product can be peeled off at the V-shaped clamping groove, and finally the complete part is obtained.
