Description

Technical Field

[0001] The utility model relates to the field of valve spring seat processing, in particular to a feeding mechanism of valve spring seat processing and punching equipment. Background Art

[0002] The valve spring seat is an important part in the engine valve mechanism. It is usually cylindrical and has two steps with a central through hole inside. At present, the processing and forming method of the valve spring seat is mainly to cut or mill the corresponding steps on the already formed cylindrical blank and then punch it. Before punching, a feeding mechanism is required to enable the valve spring seat to be moved to the bottom of the punching machine to facilitate punching of the valve spring seat.

[0003] Chinese Patent Publication No. CN219851767U discloses a feed mechanism for punching equipment used to manufacture valve spring seats. This utility model utilizes a rotating disk that slides over a rotating shaft to reduce the vertical weight load on the motor output shaft, thereby increasing the motor's service life. This utility model relates to the technical field of punching equipment, specifically providing a feed mechanism for punching equipment used to manufacture valve spring seats.

[0004] Regarding the above-mentioned disclosed patent content, since the depth of the work station groove opened on the turntable matches the thickness of the valve spring seat, when a thicker or thinner valve spring seat needs to be processed, if the device is used directly, after the thicker valve spring seat falls into the work station groove, its excess part will still be located inside the barrel, which will block the rotation of the turntable. When the thinner valve spring seat falls into the work station groove, another valve spring seat will fall into the work station groove, which will also block the rotation of the turntable. Therefore, when processing thicker or thinner valve spring seats, it is necessary to replace the turntable and adjust the position of the barrel. However, the turntable of the device is installed on the drive shaft of the motor, and the barrel is installed on the bracket, which makes it difficult to disassemble and replace the turntable and adjust the position of the barrel, thereby reducing the applicability of the mechanism.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The following describes an embodiment of the present invention based on its overall structure.

[0036] Example 1:

[0037] A feeding mechanism of a valve spring seat processing and punching device, such as Figure 1-Figure 5 As shown, it includes a base plate 1 and a drive shaft 6. A workbench 5 is installed on the top of the base plate 1, and a support frame 12 is provided on one side of the top of the workbench 5. An adjustment component 9 is provided on the support frame 12. An elastic pad 15 is provided on one side of the top of the workbench 5. The top of the elastic pad 15 is flush with the top of the workbench 5, so that when the valve spring seat falls into the work station slot 10 directly below, the valve spring seat will hit the elastic pad 15, and the elastic pad 15 can play a certain protective role for the valve spring seat.

[0038] Specifically, the adjustment component 9 includes a groove 903 opened on one side of the support frame 12 and a slot 901 opened on the top of the drive shaft 6, and an insert block 902 is inserted into the slot 901, and the interior of the groove 903 is connected to a screw rod 905 through a bearing, and the outer wall of the screw rod 905 is sleeved with two movable seats 904, and a connecting plate 906 is installed on one side of the movable seat 904, and a barrel 14 is provided on one side of the connecting plate 906. When the turntable 8 needs to be replaced, the screw rod 905 is first rotated to move the movable seat 904 upward, and the barrel 14 is driven upward by the connecting plate 906, so that the position of the barrel 14 can be adjusted first. A through hole 13 is passed through the top of the support frame 12, and the top of the barrel 14 is passed through the through hole 13, so that the barrel 14 can pass through the through hole 13, which is convenient for subsequent adjustment of the position of the barrel 14.

[0039] Specifically, a turntable 8 is installed on the top of the insert block 902, and the turntable 8 is detachably connected to the drive shaft 6 through the insert block 902 and the slot 901. The insert block 902 is a cube structure, and the depth of the work station slot 10 is the same as the thickness of the valve spring seat. The bottom of the ball 908 fits with the top of the turntable 8. When the drive shaft 6 rotates, it will drive the insert block 902 to rotate, and then drive the turntable 8 to rotate, and then drive the work station slot 10 to rotate. The movable seat 904 is threadedly connected to the screw rod 905. The top end of the screw rod 905 passes through the support frame 12 and is connected to the knob 907, which is convenient for the staff to rotate the screw rod 905 through the knob 907. After the screw rod 905 rotates, it will drive the two movable seats 904 to move at the same time.

[0040] Specifically, a driving motor 3 is installed at the middle position of the top of the base plate 1, and the output end of the driving motor 3 is connected to the driving shaft 6 that passes through the workbench 5. When the turntable 8 needs to be rotated, the driving motor 3 can be started. The driving motor 3 can drive the driving shaft 6 to rotate, thereby driving the turntable 8 to rotate. A plurality of ball grooves 909 are provided at the bottom of the barrel 14, and balls 908 are provided inside the ball grooves 909. Four work station slots 10 are provided on the turntable 8, and one of the work station slots 10 is located directly below the barrel 14. The work station slot 10 is set so that the valve spring seat can fall into it, which is convenient for subsequent punching of the valve spring seat. A punching machine 11 is installed on the base plate 1, and the punching machine 11 is located directly above a work station slot 10. The setting of the punching machine 11 facilitates punching of the valve spring seat.

[0041] Example 2:

[0042] On the basis of the above-mentioned embodiment 1, since debris is generated during the punching process, in order to prevent the debris from accumulating inside the station slot 10, the following structure is provided to collect and process the debris.

[0043] See Figure 2-Figure 3A waste outlet 7 is provided on one side of the top of the workbench 5. The diameter of the waste outlet 7 is smaller than the diameter of the work station slot 10. A waste box 2 and a receiving box 4 are placed on the top of the base plate 1 respectively. The waste box 2 is located directly below the waste outlet 7. The waste outlet 7 is set so that the debris generated during the punching process can fall downward, which is convenient for collecting the waste and preventing the waste from accumulating inside the work station slot 10. The debris will fall into the waste outlet 7 and then fall into the inside of the waste box 2 through the waste outlet 7.

[0044] Example 3:

[0045] On the basis of the above-mentioned embodiment 1, in order to facilitate the collection of the valve spring seat after punching, the following structure is provided.

[0046] See Figure 2 A blanking port 16 is provided on the top of the workbench 5. The size of the blanking port 16 is larger than the diameter of the work station slot 10. The receiving box 4 is located directly below the blanking port 16 so that the valve spring seat after punching can move to the blanking port 16 and then fall into the inside of the receiving box 4 through the blanking port 16, so that the valve spring seat after punching can be collected.

[0047] The working principle of the present utility model is as follows: first, the staff can install the equipment and connect the power supply, and then stack the valve spring seats inside the barrel 14, and then start the drive motor 3. The drive motor 3 can drive the drive shaft 6 to rotate, and then drive the work station slot 10 to rotate. When the work station slot 10 is rotated to the bottom of the barrel 14, the lowermost valve spring seat will fall into the work station slot 10 under the action of gravity. At this time, the drive motor 3 continues to drive the drive shaft 6 to rotate, driving the work station slot 10 to rotate, and driving the valve spring seat to rotate, so that the valve spring seat rotates to the bottom of the punching machine 11, thereby completing the feeding, and then turn off the drive motor 3 and start the punching machine 11. The valve spring seat is punched by the punching machine 11, and the waste generated during the punching process will fall into the waste box 2 through the waste outlet 7;

[0048] After the punching is completed, the driving motor 3 drives the driving shaft 6 to continue to rotate, and then drives the valve spring seat with the punched hole to rotate, so that the valve spring seat is rotated into the blanking port 16 and falls into the inside of the receiving box 4;

[0049] When the turntable 8 needs to be replaced in order to meet the feeding needs of valve spring seats of different thicknesses, the staff first rotates the screw rod 905 to move the movable seat 904 upward, and drives the barrel 14 upward through the connecting plate 906, so that the barrel 14 no longer blocks the turntable 8. Then the staff can take out the turntable 8 upward, so that the plug 902 is removed from the inside of the slot 901, and then insert the plug 902 at the bottom of the thicker or thinner turntable 8 into the inside of the slot 901 to position the turntable 8. Then, the screw rod 905 is rotated in the opposite direction to move the movable seat 904 downward, and then drive the barrel 14 downward, so that the ball 908 at the bottom of the barrel 14 contacts the top of the turntable 8, so as to limit the turntable 8 and prevent the turntable 8 from moving upward, so that the feeding needs of valve spring seats of different thicknesses can be met.
