The first jig includes a first jig body installed on the base. The other end of the first jig body relative to the connecting base is provided with a first stroke groove located in the middle and distributed along the axis direction with both ends open. A push rod is slidably fitted in the first stroke groove. The other end of the push rod relative to the linkage drive assembly is linked with an assembly shaft for clamping materials to be assembled. The push rod is linked with a drive assembly. The drive assembly drives the push rod and the assembly shaft to perform reciprocating linear motion along the axis of the first stroke groove. An intermittent material clamping assembly for intermittently linking the materials to be assembled is provided at the end of the first stroke groove facing the first jig. A blanking mechanism is provided above the intermittent material clamping assembly on the first jig body.

[0006] By adopting the above technical solution, the first fixture is used to clamp the end cover, shaft sleeve and other materials to be assembled, and the second fixture is used to clamp the hinge to be assembled. The first fixture cooperates with the second fixture to realize the automatic assembly of the end cover, shaft sleeve and hinge, etc., which reduces the labor intensity of manual labor, improves the assembly efficiency, and is suitable for mass production; wherein the first stroke groove mainly plays a guiding role, helps the push rod and the assembly shaft to move linearly, and the push rod, driven by the driving component, first pushes the assembly shaft to connect with the end cover, shaft sleeve and other materials to be assembled, because the end cover, The shaft sleeve and the hinge are mostly interference fit, so the assembly shaft needs to be connected with the end cover and the shaft sleeve first, so that the end cover, shaft sleeve and other materials to be assembled can be pushed accurately into the shaft hole of the hinge to complete the assembly; the main function of the intermittent material clamping assembly is to fix the position of the end cover and shaft sleeve during the connection process of the assembly shaft with the end cover and shaft sleeve, so as to facilitate the connection of the assembly shaft with the end cover and shaft sleeve; the blanking mechanism is mainly used to blank the end cover, shaft sleeve and other materials to be assembled, and transport them to the intermittent material clamping assembly in sequence and in an orderly manner.

[0007] The above-mentioned semi-automatic hinge shaft assembly fixture can be further configured as follows: the intermittent material clamping assembly includes a first clamping block fixedly mounted on the base and located at the end of the first stroke groove and below the blanking mechanism; a linkage hole that can slide with the assembly shaft is provided in the middle of the first clamping block and along the axis direction of the first stroke groove; the first clamping block is provided with a material clamping groove distributed along a direction perpendicular to the axis direction of the first stroke groove and open at both ends toward the second fixture; the material clamping groove is open toward the second fixture; spring sheets and spring return parts linked to the spring sheets are provided on both sides of the first clamping block; the end of the spring sheet extends to the material clamping groove; the other end of the spring sheet away from the material clamping groove is intermittently contacted with the push rod, and the push rod drives the spring sheet to perform reciprocating linear motion along a direction perpendicular to the axis direction of the first stroke groove.

[0008] By adopting the above technical scheme, the main function of the intermittent material clamping assembly is to fix the position of the end cover and the shaft sleeve during the connection process of the assembly shaft with the end cover and the shaft sleeve, so as to facilitate the connection of the assembly shaft with the end cover and the shaft sleeve; wherein, the material clamping groove is mainly used to receive the end cover, shaft sleeve and other materials to be assembled, and the "end of the spring piece extends to the material clamping groove" can limit the material to be assembled.

After the connection between the two is completed, the push rod continues to push forward, and at the same time the spring piece moves in a direction perpendicular to the axis of the first stroke groove, and then the end of the spring piece exits the material clamping groove, and the push rod continues to push the assembly shaft forward, and the assembly shaft then drives the material to be assembled and the hinge to be assembled to complete the assembly. The whole process does not require manual labor, and the assembly is highly accurate and there is no jamming.
