[0035] In order to solve the limitations of the prior art, this embodiment provides a technical solution, and the technical solution of the utility model is further described below in conjunction with the drawings and embodiments.
[0036] See attached Figure 1 The utility model is mainly used for effectively positioning the parts to be pressed during the press-fitting operation, and avoiding the downward movement of the stamping part during the press-fitting process. The parts to be pressed here include fasteners 104 and clips 105. The press-fitting process requires that the fasteners 104 be completely pressed into the inner hole of the clips 105. Compared with the poor positioning effect of the positioning mechanism in the related art, which leads to poor press-fitting quality and low press-fitting efficiency, the present application can achieve the positioning and limiting of the parts to be pressed by setting the carrier body and the movable support 103, and avoid the downward moving stamping part during press-fitting, which is beneficial to improving the pressing efficiency and pressing quality; through the specific structure of the carrier assembly 100 and the setting of the elastic member, the purpose of avoiding the upward and downward movement of the movable support 103 is well achieved, and the positioning and limiting of the parts to be pressed is guaranteed. The specific structure of the present application is as follows:
[0037] See attached Figure 1-5 A carrier assembly 100 for press-fitting positioning includes a carrier body, a movable support member 103 and an elastic member. The movable support member 103 and the elastic member are both installed inside the carrier body, and the movable support member 103 moves up and down relative to the carrier body under the action of the elastic member. Specifically:
[0038] See attached Figure 3-6 , the carrier body is used to support the components to be pressed and to provide a receiving cavity for installing the movable support member 103; specifically, the carrier body includes a bottom plate 101 and a top plate 102 that are relatively fixedly installed. The relatively fixed installation here can be detachably installed by screws or other means or fixedly installed by welding, etc. A number of limiting holes 1021 are set on the top plate 102, and a number of guide brackets 1011 corresponding to the limiting holes 1021 and concentric with the limiting holes 1021 are set on the bottom plate 101. The function of the guide bracket 1011 here is to support the fastener 104, and an receiving cavity for installing the movable support member 103 is formed between the limiting holes 1021 and the guide bracket 1011 as well as the top plate 102 and the bottom plate 101.
[0039] See attached Figure 7 The movable support member 103 is used to assist the carrier body in positioning the components to be pressed and to avoid the stamping part during press-fitting. Specifically, the movable support member 103 is slidably installed in the accommodating cavity of the carrier body along the vertical direction, and an elastic member is installed between the movable support member 103 and the carrier body. The elastic member is a spring 106 or a spring sheet, and the top of the elastic member is pressed tightly against the bottom surface of the movable support member 103, and the bottom of the elastic member is pressed tightly against the bottom plate 101. The elastic member is used to generate an upward thrust on the movable support member 103 and shrinks during press-fitting so that the movable support member 103 moves downward to avoid the stamping part. The movable support member 103 includes a concentrically arranged chassis 1031 and a sliding column 1032. The size of the chassis 1031 is larger than that of the sliding column 1032. The shapes of the two constitute an inverted T-shaped structure. The centers of the chassis 1031 and the sliding column 1032 form an inner sliding hole 1033 that slides with the guide bracket 1011. The top surface of the sliding column 1032 is provided with an annular concave supporting groove 10321. By setting the specific structure of the movable support member 103, with the help of the inner sliding hole 1033 and the supporting groove 10321, it is beneficial to achieve the stability of the up and down movement of the movable support member 103 and to limit the components to be pressed, which is beneficial to ensure the quality of pressing and avoid pressing failure due to the offset of the parts to be pressed.
[0040] See attached Figure 5-7, the limiting hole 1021 is set as an inverted T-shaped structure, the chassis 1031 and the slide column 1032 of the movable support 103 are set as an inverted T-shaped structure matching the shape of the limiting hole 1021, and the limiting groove 10211 for the clamping protrusion 1035 to slide up and down is set on the side wall of the limiting hole 1021 of the top plate 102. At least one clamping protrusion 1035 extending in the radial direction is set on the outer peripheral surface of the chassis 1031, and the number of the clamping protrusion 1035 here is one, and the clamping protrusion 1035 here can be a rectangular parallelepiped, a cube or a hemispherical shape. By setting the clamping protrusion 1035 and the limiting groove 10211, it is conducive to achieving the stability of the movable support 103 moving up and down. A plurality of avoidance grooves 1034 extending in the axial direction are set on the top of the slide column 1032. By setting the avoidance grooves 1034, it is convenient to provide an avoidance space for the clamping claws of the clamping assembly when placing parts. A transition portion 10322 is provided at the connection between the supporting groove 10321 and the inner sliding hole 1033. The transition portion 10322 is provided as a chamfer, and the chamfer angle is between 0 and 90 degrees, preferably 45 degrees. By providing the transition portion 10322, it is convenient for the press-fitted parts to enter the supporting groove 10321 quickly when they are placed, and at the same time, the press-fitted parts are protected from collision. The shape of the supporting groove 10321 of the movable support 103 matches the shape of the bottom surface of the buckle clip 105. By providing the supporting groove 10321 of the movable support 103 matches the shape of the bottom surface of the buckle clip 105, it is convenient to position the buckle clip 105 more effectively.
[0041] When the carrier assembly 100 of the utility model is used for press-fitting and positioning, in the natural state, under the elastic force of the elastic member, the movable support member 103 is pressed tightly in the limiting hole 1021 of the top plate 102, and the movable support member 103 protrudes from the upper surface of the top plate 102 and the upper surface of the guide support platform 1011. First, the automatic clamping assembly clamps the fastener 104 and places it on the upper surface of the guide support platform 1011, and then clamps the buckle clip 105 and places it above the buckle 104. At this time, the bottom surface of the buckle clip 105 is aligned with the supporting groove 1032 of the movable support member 103. 1 fit, the stamping part performs vertical downward pressing, exerts force on the upper surface of the clip 105 to drive the clip 105 and the fastener 104 to fit together, at this time, the clip 105 moves downward and presses the movable support member 103 to make it move downward, the elastic member under the movable support member 103 is compressed, and the movable support member 103 moves downward along the limiting hole 1021 to provide an escape space for the stamping part. During the whole process, the movable support member 103 and the clip 105 are always in a contact and positioning state, thereby effectively ensuring the positioning accuracy of the fastener 104 and the clip 105 during the press-fitting process.
