Description

Technical Field

[0001] The present invention relates to the technical field of automotive part processing, and more particularly to an automatic installation mechanism for a return spring of an automotive door base. Background Art

[0002] During the processing of automotive doors, multiple different parts need to be assembled. Among them, the automotive door base is an important component of the automotive door. When the automotive door base is processed, a return spring needs to be installed to ensure that the base can operate normally in the car door. Usually, a specific installation device is used to automatically install the return spring. However, the existing return spring installation devices cannot accurately control the position and angle of the spring during use, resulting in position deviation after the return spring is installed, which will affect the normal use of the entire base. In addition, the working efficiency of the entire device is low and it is more troublesome to use. Therefore, we have made improvements and proposed an automatic installation mechanism for a return spring of an automotive door base. Summary of the Invention

[0009] Preferably, the spring retaining piece mechanism includes a second cylinder fixedly installed on the upper surface of the base plate. The output end of the second cylinder is provided with a first connecting part. One side of the upper end of the first connecting part is fixedly installed with a connecting rod, and the other end of the connecting rod is provided with a spring retaining piece.

[0010] Preferably, the spring retaining piece is arranged on one side inside the spring installation fixture. The spring installation fixture is installed on one side of the fixed seat. The fixed seat is fixedly installed on the upper surface of the workbench, and a spring pre-pushing mechanism is installed on the upper surface of the fixed seat.

[0011] Preferably, the spring pre-pushing mechanism includes a third cylinder, a second connecting part, and a pre-pushing push rod. The third cylinder is fixedly installed on one side of the upper surface of the fixed seat. The second connecting part is installed at the output end of the third cylinder. One end of the pre-pushing push rod is installed on one side of the second connecting part, and the other end of the pre-pushing push rod is arranged on one side of the spring installation fixture.

[0012] Preferably, a second mounting plate is fixedly installed on the upper surface of the fixed seat and on one side of the spring pre-pushing mechanism. A spring pressing-down mechanism is installed on the top of the second mounting plate.

[0013] Preferably, the spring pressing-down mechanism includes a fourth cylinder, a third connecting part, a pressing-down limiting plate, and a spring pressing wheel. The fourth cylinder is fixedly installed on one side surface of the upper end of the second mounting plate. The output end of the fourth cylinder is provided with a third connecting part. The pressing-down limiting plate is fixedly installed on the lower surface of the third connecting part, and the spring pressing wheel is arranged at the bottom of the pressing-down limiting plate.

[0014] Preferably, a fifth cylinder is installed on one side of the upper surface of the fixed seat. The output end of the fifth cylinder penetrates through the fixed seat and the end part is arranged on one side of the spring installation fixture.

The pre-pushing push rod in the spring pre-pushing mechanism pushes the return spring in the spring installation fixture to the 70° position to complete the preliminary position and angle adjustment work, which facilitates the secondary adjustment work of the position and angle of the return spring by the spring pressing mechanism. By pressing down the spring pressing wheel in the spring pressing mechanism, the return spring is pressed down to the 190° position, thereby completing the second adjustment of the spring position and angle, making the spring position state and angle in the state when installed in the base, and being more accurate in position during installation without position deviation, thus not affecting the normal use of the base.

[0019] 2. The spring pressing mechanism can simultaneously fix the fixtures in the base support fixtures on both sides of the workbench, and the position fixation is more stable, and it is not easy to produce position deviation during the spring propulsion process. The base support fixtures and spring installation mechanisms arranged on both sides of the first station and the second station can simultaneously perform spring installation work on two groups of bases. By pressing down one side of the base pressing mechanism through the pressing blocks arranged at both ends of the lower surface of the first mounting plate, the fixation work of the bases in the base support fixtures on both sides can be completed, which can effectively improve the working efficiency of the entire equipment and is more convenient to use.

[0029] Embodiment

[0030] As Figure 1-7 shown, an automatic installation mechanism for a reset spring of an automobile door base includes a base 1. A workbench 2 is fixedly installed on the upper surface of the base 1. A first station 5 and a second station 6 are respectively arranged at both ends of one side of the upper surface of the workbench 2. Base support fixtures 7 are installed on the upper surface of the workbench 2 and on one side of the first station 5 and the second station 6. A pin punching mechanism 4 is arranged on the upper surface of the workbench 2 and on one side of each base support fixture 7. A spring installation mechanism 9 is arranged on the upper surface of the workbench 2 and outside the first station 5 and the second station 6. A mounting bracket 3 is fixedly arranged on the upper surface of the base 1 and on one side of the workbench 2. A base pressing mechanism 8 is arranged at the upper end of the mounting bracket 3.

[0031] In this embodiment, the spring installation mechanism 9 includes a base plate 901 and a spring retaining plate mechanism 902. The base plate 901 is fixedly installed at one end of the upper surface of the workbench 2, and the spring retaining plate mechanism 902 is installed on the upper surface of the base plate 901. The spring retaining plate mechanism 902 includes a second cylinder 9021, which is fixedly installed on the upper surface of the base plate 901. A first connecting portion 9022 is provided at the output end of the second cylinder 9021. One side of the upper end of the first connecting portion 9022 is fixedly installed with a connecting rod 9023, and the other end of the connecting rod 9023 is provided with a spring retaining plate 9024. The spring retaining plate 9024 is arranged on one side inside the spring installation fixture 903. The spring installation fixture 903 is installed on one side of a fixed seat 904. The fixed seat 904 is fixedly installed on the upper surface of the workbench 2, and a spring pre-pushing mechanism 905 is installed on the upper surface of the fixed seat 904. By raising the spring retaining plate 9024 in the spring retaining plate mechanism 902, the position of the spring in the spring installation fixture 903 can be fixed, facilitating the spring pre-pushing mechanism 905 and the spring pressing-down mechanism 907 to adjust the position and angle of the spring, which is more convenient during use.

[0032] Specifically, the spring pre-pushing mechanism 905 includes a third cylinder 9051, a second connecting portion 9052, and a pre-pushing push rod 9053. The third cylinder 9051 is fixedly installed on one side of the upper surface of the fixed seat 904. The second connecting portion 9052 is installed at the output end of the third cylinder 9051. One end of the pre-pushing push rod 9053 is installed on one side of the second connecting portion 9052, and the other end of the pre-pushing push rod 9053 is arranged on one side of the spring installation fixture 903. By pushing the spring in the spring installation fixture 903 with the pre-pushing push rod 9053 in the spring pre-pushing mechanism 905, the preliminary position and angle adjustment work of the spring can be carried out, facilitating the secondary adjustment work of the spring position and angle by the spring pressing-down mechanism 907.

[0033] Among them, a second mounting plate 906 is fixedly installed on the upper surface of the fixed seat 904 and on one side of the spring pre-pushing mechanism 905. A spring pressing-down mechanism 907 is installed on the top of the second mounting plate 906. The spring pressing-down mechanism 907 includes a fourth cylinder 9071, a third connecting portion 9072, a pressing-down limiting plate 9073, and a spring pressing wheel 9074. The fourth cylinder 9071 is fixedly installed on one side surface of the upper end of the second mounting plate 906. A third connecting portion 9072 is provided at the output end of the fourth cylinder 9071. The pressing-down limiting plate 9073 is fixedly installed on the lower surface of the third connecting portion 9072, and the spring pressing wheel 9074 is arranged at the bottom of the pressing-down limiting plate 9073. By pressing down the spring pressing wheel 9074 in the spring pressing-down mechanism 907, the second adjustment of the spring position and angle can be completed, enabling the spring position state and angle to be in the state when installed in the base, being more accurate during installation, without generating position deviation, and thus not affecting the normal use of the base.

[0034] In the present application, a fifth cylinder 908 is installed on one side of the upper surface of the fixed seat 904. The output end of the fifth cylinder 908 penetrates through the fixed seat 904 and the end is disposed on one side of the spring installation fixture 903. By providing the fifth cylinder 908, the spring in the spring installation fixture 903 can be pushed into the base, which is more convenient to use.

[0035] It should be noted that the base pressing mechanism 8 includes a support frame 801 and a first cylinder 802. The support frame 801 is fixedly installed on the upper surface of the installation frame 3. The first cylinder 802 is installed inside the support frame 801. The output end of the first cylinder 802 penetrates through the upper end of the installation frame 3 and a connection installation frame 803 is installed at the end. A first mounting plate 804 is fixedly installed at the bottom of the connection installation frame 803. Pressing blocks 805 are fixedly installed at both ends of the lower surface of the first mounting plate 804. By means of the base pressing mechanism 8, the fixtures in the base support fixtures 7 on both sides of the workbench 2 can be fixed simultaneously, and the position fixation is more stable. During the process of spring propulsion, position deviation is not likely to occur, which is more convenient to use.

[0036] The working principle of the automatic installation mechanism for the reset spring of the vehicle door base:

[0037] During use, place the door base to which the return spring is to be installed and reset into the base support fixture 7, and clamp and fix the base through the base support fixture 7 to prevent the base from having a position deviation during the spring installation process. Place the return spring to be installed through the spring installation fixture 903. Push the first connecting portion 9022 upward by the second cylinder 9021 in the spring retaining mechanism 902, and move the spring retaining piece 9024 in the spring installation fixture 903 upward under the action of the connecting rod 9023, so as to block the return spring in the spring installation fixture 903, which is convenient for adjusting the angle of the spring. Push the second connecting portion 9052 to move by the third cylinder 9051 in the spring pre-pushing mechanism 905, and then drive the pre-pushing push rod 9053 to move forward, so that it pushes the spring in the spring installation fixture 903 to move, and the spring angle is retracted to the 70° position. Then, push the third connecting portion 9072 downward by the fourth cylinder 9071 in the spring pressing mechanism 907, and then drive the downward pressing limit plate 9073 to move downward, so that the spring pressing wheel 9074 at the bottom of the downward pressing limit plate 9073 presses the spring, and the return spring is retracted to 190°, so that the spring position state is in the state when it is installed in the base. Then, push the connecting installation frame 803 downward by the first cylinder 802 in the base pressing mechanism 8, so that the downward pressing block 805 at the bottom of the first mounting plate 804 moves downward, and it cooperates with the base of the base support fixture 7, so as to fix the position of the base. Then, push the return spring into the base by the fifth cylinder 908. Then, drive the Pin into the temporal part of the base through the Pin driving mechanism 4 to fix the return spring inside the base. After the installation is completed, each mechanism is reset to facilitate the next installation work. The base support fixture 7 and the spring installation mechanism 9 provided on both sides of the first station 5 and the second station 6 can simultaneously perform the spring installation work on two groups of bases. The downward pressing block 805 provided at both ends of the lower surface of the first mounting plate 804 can fix the bases in the two base support fixtures 7 on one side by pressing downward on one side of the base pressing mechanism 8, which can effectively improve the working efficiency of the entire device.
