DETAILED DESCRIPTION

[0029] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0030] like Figure 1-7 As shown, in this embodiment, an automatic assembly tool for the rotating shaft of an automobile armrest box is provided, which is mainly composed of a frame 1, a press-fitting assembly 2, an X-direction limit block 3, two Y-direction limit blocks 4, four contoured positioning blocks 5, and two clamping mechanisms 6. Among them, the press-fitting assembly 2 is arranged at one end of the top of the frame 1, and the press-fitting assembly 2 can synchronously press-fit the two rotating shafts of the fixed armrest box product 9.

[0031] Specifically, the X-direction limit block 3, two Y-direction limit blocks 4, four contour positioning blocks 5 and two clamping mechanisms 6 are all installed on the top of the frame 1. The X-direction limit block 3 and the two Y-direction limit blocks 4 are slightly higher. The X-direction limit block 3 can limit one side of the armrest box product 9, that is, the press-fitting direction of the press-fitting component 2 is the X-direction; the two Y-direction limit blocks 4 can limit the adjacent side of the armrest box product 9, that is, the horizontal direction perpendicular to the X-direction is the Y-direction; the four contour positioning blocks 5 are slightly shorter, adapted to the bottom profile of the armrest box product 9, and can position and stabilize the bottom of the armrest box product 9. In this way, when placing the armrest box product 9, the armrest box product 9 can be initially positioned and stabilized by the X-direction limit block 3, two Y-direction limit blocks 4, and four contour positioning blocks 5, and then the two clamping mechanisms 6 are used to limit, clamp and fix the two ends of the top surface of the positioned armrest box product 9. Finally, the two rotating shafts of the fixed armrest box product 9 are synchronously pressed through the pressing component 2. In this way, the double rotating shafts of the armrest box product 9 can be automatically pressed synchronously without manual pressing, which reduces manpower, improves work efficiency and ensures the accuracy of pressing.

[0032] At the same time, the product positioning tooling of this embodiment can first position and stabilize the two side edges and the bottom of the armrest box product 9 through the design of an X-axis limit block 3, two Y-axis limit blocks 4, four contoured positioning blocks 5 and two clamping mechanisms 6, and then the two clamping mechanisms 6 can clamp and fix the two ends of the top surface of the armrest box product 9 by limiting the nature, so as to achieve all-round fixation and high positioning stability. It can ensure the stability of the armrest box product 9 during press-fitting, improve the accuracy of press-fitting, reduce the accuracy influence caused by the error of the armrest box product 9 itself, and is conducive to the improvement of the yield rate.

[0033] Specifically, each clamping mechanism 6 in this embodiment is composed of a rotating fixed seat 61 and a pressure block baffle 62 fixed on the top of the frame 1, a contoured pressure block 60 rotatably mounted on the rotating fixed seat 61, and a first knurled screw 63 threadedly assembled on the pressure block baffle 62. When the armrest box product 9 is placed in the initial position, the contoured pressure block 60 is in an open state. When it is necessary to clamp, the contoured pressure block 60 can be rotated and pressed down; wherein, when the armrest box product 9 is clamped, one end of the contoured pressure block 60 is located between the first knurled screw 63 and the pressure block baffle 62, and the contoured pressure block 60 can be locked and fixed with the pressure block baffle 62 by rotating the first knurled screw 63. The contoured pressure block 60 can perfectly fit the contours of the two ends of the top surface of the armrest box product 9, so the positioning and fixing accuracy and stability effect can be improved during clamping.

[0034] It is worth mentioning that the bottom of the end of the profiling block 60 away from the rotating fixed seat 61 in this embodiment is also provided with a positioning bayonet 600. When the profiling block 60 presses the armrest box product 9, the positioning bayonet 600 can be clamped on the first knurled screw 63 and then locked by rotating the first knurled screw 63. The positioning bayonet 600 on the profiling block 60 can be limited again with the first knurled screw 63 before being locked, so that the pressing and positioning accuracy of the profiling block 60 and the stability effect after pressing can be guaranteed.

[0035] In addition, a second knurled screw 64 is provided on the side of the end of the profiling pressing block 60 away from the rotating fixed seat 61 in this embodiment. The second knurled screw 64 can facilitate people to rotate the profiling pressing block 60. Of course, the second knurled screw 64 can also serve as a temporary backup when the first knurled screw 63 is damaged.

[0036] Specifically, the press-fitting assembly 2 in this embodiment is composed of two press-fitting cylinders 20 and an external cover body 22 and other components. The two press-fitting cylinders 20 are horizontally installed on the top of the frame 1 through the cylinder seats 21 respectively, and the output end of each press-fitting cylinder 20 faces the clamping mechanism 6 and is provided with a pressing head 200. When the armrest box product 9 is completely fixed, the two press-fitting cylinders 20 can synchronously drive the pressing head 200 to move horizontally and synchronously press the two rotating shafts of the armrest box product 9. The cover body 22 is installed on the frame 1 and is located outside the two press-fitting cylinders 20, which can play a protective role during work.

[0037] Of course, some function buttons 7, such as a start button, a reset button, an emergency stop button, etc., are also provided on the front side of the frame 1 of the present embodiment, so that people can directly press and automatically press the frame 1. Rollers 8 are also provided at the bottom end of the frame 1 to facilitate the position of the overall device.
