Description

Technical Field

[0001] This utility model relates to the field of fuel injector component processing technology, specifically a material clamping structure for a cold heading machine. Background Technology

[0002] A cold heading machine is a forging and forming device that thickens the top of bars or wires at room temperature. It is a specialized machine mainly used for the mass production of fasteners such as nuts and bolts. When processing parts of fuel injectors, some parts can be processed by a cold heading machine, such as the clamping cap and simple cylindrical push rod in the fuel injector. This can be mass-produced by a cold heading machine to improve production efficiency. This solution only improves the clamping of clamping caps and simple cylindrical push rods when processed by a cold heading machine. The current traditional V-shaped clamps are prone to workpiece rotation when clamping, and traditional clamps are insufficient in clamping force when clamping round parts, such as push rods, which can easily lead to slippage and affect the processing quality. To address the above problems, the inventor proposes a material clamping structure for a cold heading machine to solve the above problems. Utility Model Content

[0003] In order to solve the problem of unstable clamping when processing some parts of the fuel injector using a cold heading machine, the purpose of this utility model is to provide a material clamping structure for a cold heading machine.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a material clamping structure for a cold heading machine, comprising a housing, an inner ring slidably connected inside the housing, guide plates fixedly connected to both the upper and lower surfaces of the ring, teeth fixedly connected to the inner wall of the ring, a protruding post fixedly connected to the outer wall of the ring, a vertical plate fixedly connected to the end face of the protruding post, a cavity provided on the side of the vertical plate facing away from the housing, a protruding ring fixedly connected to the inner wall of the cavity, a toothed ring rotatably connected to one side of the protruding ring, a convex cavity fixedly connected to the outer wall of the cavity, a second motor disposed inside the convex cavity, a worm fixedly connected to the output shaft end of the second motor, a horizontal shaft rotatably connected to the side wall of the convex cavity, a worm wheel fixedly connected to one end of the horizontal shaft, a transmission gear fixedly connected to the other end of the horizontal shaft, the worm wheel corresponding to and meshing with the worm, the transmission gear corresponding to and meshing with the toothed ring, a toothed plate meshing with the side wall of the transmission gear and on one side of the toothed ring, and a clamping plate fixedly connected to the end face of the toothed plate.

[0005] Preferably, a first motor is inserted through the side wall of the housing. A half-face gear is fixedly connected to the output shaft of the first motor. The half-face gear has corresponding and meshing teeth. Starting the first motor causes the half-face gear to rotate. Through the meshing of the half-face gear and the teeth, and with the cooperation of the guide plate, the ring can move up and down. In turn, the convex column can drive the vertical plate to move up and down. The connecting rod can make the cavity move up and down. It should be noted that each up and down movement of the cavity is related to the punch die. Corresponding to the cold heading cavity, a pressing end is provided on one side of the cavity, and a punch is provided on the other side of the cavity. The punch includes a cold heading cavity. When cold heading the ejector rod in the injector, the ejector rod can be clamped by this device, so that the ejector rod corresponds with the uppermost first punch. The workpiece end can be initially pressed by the pressing end. Then, the vertically moving cavity can move the initially pressed workpiece end to the second punch for secondary pressing. This operation is repeated until the forming is completed with the cooperation of each punch.

[0006] Preferably, a first base is provided on the side wall of the first motor, and the side wall of the first base is fixedly connected to the inner wall of the housing. A connecting rod is fixedly connected to the outer wall of the cavity, and the end of the connecting rod away from the cavity is fixedly connected to the side wall of the vertical plate. The first motor is installed through the first base. Fastening bolts are inserted through the side wall of the housing, and the housing can be installed and fixed by the fastening bolts. A rotating ring is fixedly connected to the side wall of the gear ring, and the rotating ring is rotatably connected to the convex ring. When the second motor is started, the worm rotates under the action of the output shaft of the second motor. Through the mutual meshing of the worm and the worm wheel, the horizontal shaft can be rotated, which in turn can cause the transmission gear to rotate. Through the mutual meshing of the transmission gear and the gear ring, and With the cooperation of the rotating ring, the other three transmission gears can rotate. Through the meshing of the transmission gears and the toothed plate, the four clamping plates can move synchronously to clamp the top rod. The side wall of the second motor is provided with a second base, and the side wall of the second base is fixedly connected to the inner wall of the convex cavity. There are four transmission gears, and the four transmission gears are arranged in an array with the axis of the toothed ring as the center. The second motor is installed through the second base. The bottom surface of the toothed plate is fixedly connected with a slide rail, and the inner wall of the convex ring is provided with a slide groove. The slide rail and the slide groove correspond to and are slidably connected. When the toothed plate moves horizontally, the cooperation between the slide rail and the slide groove makes the movement of the toothed plate more stable.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: stable clamping. For example, when processing the ejector rod inside the injector through a cold heading machine, this device can center and clamp the ejector rod inside the injector so that it can be formed in cooperation with the pressing end and the die. This avoids the situation where the offset occurs during clamping and affects the processing quality, thereby improving the pass rate. Attached Figure Description

[0016] Example: Figure 1-5As shown, this utility model provides a material clamping structure for a cold heading machine, including a housing 1. A ring 6 is slidably connected inside the housing 1.

A toothed ring 15 is rotatably connected to one side of the protruding ring 13. A toothed ring 15 is fixedly connected to the outer wall of the cavity 12. A convex cavity 16 is provided inside, and a second motor 17 is provided inside. The output shaft of the second motor 17 is fixedly connected to a worm gear 19. A horizontal shaft 21 is rotatably connected to the side wall of the convex cavity 16. A worm wheel 20 is fixedly connected to one end of the horizontal shaft 21, and a transmission gear 22 is fixedly connected to the other end of the horizontal shaft 21. The worm wheel 20 corresponds to and meshes with the worm gear 19. The transmission gear 22 corresponds to and meshes with the gear ring 15. A toothed plate 23 meshes with the side wall of the transmission gear 22 and on one side of the gear ring 15. A clamping plate 24 is fixedly connected to the end face of the toothed plate 23.

[0017] A first motor 3 is inserted through the side wall of the housing 1. A half-face gear 5 is fixedly connected to the output shaft end of the first motor 3. The half-face gear 5 corresponds to and meshes with the teeth 7.

[0018] By adopting the above technical solution, starting the first motor 3 can cause the half-face gear 5 to rotate. Through the meshing of the half-face gear 5 and the teeth 7, and with the cooperation of the guide plate 8, the ring body 6 can move up and down. This, in turn, can drive the vertical plate 10 to move up and down via the protruding post 9. The connecting rod 11 can cause the cavity 12 to move up and down. It should be noted that each up and down movement of the cavity 12 corresponds to the cold forging cavity of the die 27. One side of the cavity 12 is provided with a forging end 26, and the other side of the cavity 12 is provided with the die 27. Figure 1 As shown, the die 27 includes a cold heading cavity. When the ejector rod inside the injector is cold-headed, the ejector rod can be clamped by this device, so that the ejector rod corresponds with the uppermost first die 27. The workpiece end can be initially pressed by the pressing end 26. Then, the vertically moving cavity 12 can move the initially pressed workpiece end to the second die 27 for secondary pressing. This process is repeated until the forming is completed with the cooperation of each die 27.

[0019] The first motor 3 has a first base 4 on its side wall. The side wall of the first base 4 is fixedly connected to the inner wall of the housing 1. A connecting rod 11 is fixedly connected to the outer wall of the cavity 12. The end of the connecting rod 11 away from the cavity 12 is fixedly connected to the side wall of the vertical plate 10.

[0020] By adopting the above technical solution, the first motor 3 is installed through the first base 4, and fastening bolts 2 are inserted through the side wall of the housing 1, so that the housing 1 can be installed and fixed by fastening bolts 2.

[0021] A rotating ring 14 is fixedly connected to the side wall of the toothed ring 15, and the rotating ring 14 is rotatably connected to the convex ring 13.

[0022] By adopting the above technical solution, the second motor 17 is started, and the worm 19 rotates under the action of the output shaft of the second motor 17. Through the meshing of the worm 19 and the worm wheel 20, the horizontal shaft 21 can be rotated, which in turn causes the transmission gear 22 to rotate. Through the meshing of the transmission gear 22 and the gear ring 15, and with the cooperation of the rotating ring 14, as... Figure 4 as well as Figure 5 As shown, this allows the other three transmission gears 22 to rotate. Through the meshing of the transmission gears 22 and the toothed plate 23, the four clamping plates 24 can move synchronously to clamp the push rod.

[0023] The second motor 17 has a second base 18 on its side wall. The side wall of the second base 18 is fixedly connected to the inner wall of the cavity 16. There are four transmission gears 22, and the four transmission gears 22 are arranged in an array with the axis of the gear ring 15 as the center.

[0024] By adopting the above technical solution, the second motor 17 is installed through the second base 18.

[0025] The bottom surface of the toothed plate 23 is fixedly connected to the slide rail 25, and the inner wall of the convex ring 13 is provided with a slide groove. The slide rail 25 corresponds to the slide groove and is slidably connected.

[0026] By adopting the above technical solution, when the toothed plate 23 moves horizontally, the cooperation between the slide rail 25 and the slide groove makes the movement of the toothed plate 23 more stable.

[0027] Working principle: When this utility model is in use, when the ejector rod inside the injector needs to be processed by a cold heading machine, the ejector rod can be clamped and fixed by this device, so that the ejector rod corresponds with the uppermost first punch 27. The workpiece end can be initially pressed by the pressing end 26. Then, the first motor 3 is started to make the half-face gear 5 rotate. Through the meshing of the half-face gear 5 and the teeth 7, and with the cooperation of the guide plate 8, the ring body 6 can be moved vertically. Then, the vertical plate 10 can be moved vertically by the protruding column 9. The cavity 12 can be moved vertically by the connecting rod 11. The vertically moving cavity 12 can move the initially pressed workpiece end to the second punch 27 for secondary pressing. This operation is repeated until the forming is completed with the cooperation of each punch 27.

[0028] The specific operation during clamping is as follows: When the push rod is located inside the cavity of the cavity 12, the second motor 17 is started. The worm gear 19 rotates under the action of the output shaft of the second motor 17. Through the meshing of the worm gear 19 and the worm wheel 20, the horizontal shaft 21 can be rotated, which in turn causes the transmission gear 22 to rotate. Through the meshing of the transmission gear 22 and the gear ring 15, and with the cooperation of the rotating ring 14, as... Figure 4 as well as Figure 5 As shown, this allows the other three transmission gears 22 to rotate. Through the meshing of the transmission gears 22 and the toothed plate 23, the four clamping plates 24 can move synchronously to center and clamp the push rod.
