Technical Field

[0001] This utility model relates to an auxiliary loading and unloading device for marking and numbering nuts, specifically a device for marking and unloading snap-fit ​​nuts, belonging to the field of marking technology. Background Technology

[0002] Nuts are common precision parts, and their types and specifications are distinguished by markings engraved on their surface for easy identification. Engraving these markings on nuts requires specialized stamping equipment, which uses a stamping head to engrave the markings onto the nut.

[0003] In the existing nut marking process, the loading and unloading of nuts is inconvenient, cannot be automated, increases working time, and also takes time to locate the nut marking, affecting the overall processing progress and resulting in low work efficiency. Utility Model Content

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0056] like Figure 1-32A device for marking and unloading snap-fit ​​nuts, as shown, includes: a base plate 1, on which a transverse pushing mechanism and a radial unloading mechanism are arranged.

The lower end of the slide base plate 2 is supported on the base plate 1 by a bracket mechanism and forms a height space with the base plate 1; a feeding mechanism is arranged on the transverse pushing mechanism, and a nut marking groove 3 is formed at the junction of the transverse pushing mechanism and the radial unloading mechanism; the radial unloading mechanism is arranged on the slide base plate 2 via a sliding mechanism; a pushing hydraulic power device is arranged below the transverse pushing mechanism, and an unloading hydraulic power device is arranged at one end of the radial unloading mechanism;

[0057] Furthermore, the feeding mechanism forms a feeding port 4 on the transverse pushing mechanism that connects to the feeding pipe 26. One end of the feeding pipe 26 is connected to the feeding port of the feeding mechanism, and the other end is connected to the vibrating plate of the feeding mechanism. Through the vibration of the vibrating plate of the feeding mechanism, a number of materials (nuts 27) are sequentially arranged and fed into the feeding pipe, and then each material is fed into the feeding port 4 of the feeding mechanism of the device from top to bottom through the feeding pipe 26.

[0058] The inside of the feeding tube is filled with nuts, and its structure and the principle of the nuts being sent into the pushing channel through the inlet are the same as the loading principle of a gun in the prior art.

[0059] Based on the above technical solution, the material nut 27 enters the inlet 4 of the feeding mechanism from the feeding pipe and reaches the transverse pushing mechanism. The transverse pushing mechanism pushes the nut laterally to the direction of the radial unloading mechanism through the action of the pushing hydraulic power device. The nut is then marked in the marking groove 3 at the junction of the transverse pushing mechanism and the radial unloading mechanism. After marking is completed, the unloading hydraulic power device is started to provide power to the radial unloading mechanism. The radial unloading mechanism slides the nut 27 in the marking groove 3 to the externally connected slide unloading groove 24 under the action of the slide mechanism. The nut then automatically enters the material box 25 through the slide unloading groove, completing the entire loading and unloading process of the device.

[0061] Furthermore, the support mechanism includes: two parallel first upright plates 5 and second upright plates 6, and a guide rail support 7; the guide rail support 7 is located between the base plate 1 and the slide base plate 2 in the direction of the tail end of the transverse pushing mechanism, the top surface of the guide rail support 7 is provided with a countersunk bolt hole for connecting with the slide base plate 2, and the lower end of the guide rail support 7 is provided with a through bolt hole for connecting with the base plate 1, and the guide rail support 7 is fixedly connected to the base plate 1 and the slide base plate 2 respectively by bolts; the first upright plate 5 and the second upright plate 6 are located below the slide base plate 2 away from the direction of the tail end of the transverse pushing mechanism and are separated from each other, the first upright plate 5 and the second upright plate 6 are respectively provided with through bolt holes for connecting with the base plate 1, and the first upright plate 5 and the second upright plate 6 are fixedly connected to the base plate 1 by bolts.

[0062] Furthermore, the slide base plate 2 has a "T" shaped structure. The slide base plate 2 is provided with a long through hole 201 in the area corresponding to the tail end of the transverse pushing mechanism. The length of the long through hole 201 accounts for half of the length of the entire slide base plate 2 and is located from the end to the middle of the slide base plate 2. The upper surface of the slide base plate 2 at the front end of the long through hole 201 is a horizontal area 202.

[0063] Furthermore, the transverse pushing mechanism is located in the elongated through-hole 201 area and the horizontal plane area 202 on the slide bottom plate 2;

[0064] The transverse pushing mechanism includes: a first baffle 8, a second baffle 9, a pushing rod 10, and bolts; the first baffle 8 and the second baffle 9 are respectively fixedly connected to the two sides of the slide bottom plate 2 by bolts; the pushing rod 10 is provided between the first baffle 8 and the second baffle 9, and the position of the pushing rod 10 corresponds to the area where the elongated through hole 201 of the slide bottom plate 2 is located; the space between the first baffle 8 and the second baffle 9 corresponding to the horizontal area 202 of the slide bottom plate forms a pushing channel; the nut is pushed in the pushing channel by the pushing rod 10;

[0065] Furthermore, a feeding mechanism is installed above the feeding channel located at the front end of the pusher rod 10. The feeding mechanism includes: a feed pipe cover plate 11 connected to the feed pipe, a feed pipe cover plate bracket 12, a pressure rod 13, and bolts. The feed pipe cover plate 11 has a feed inlet 4 that matches the shape of the nut. Bolt holes 14 for connecting to the feed pipe are located at both ends of the feed inlet 4. The feed pipe is fixed to the feed pipe cover plate 11 by bolts. The feed pipe cover plate 11 is connected to both sides of the slide base plate 2 by a hinged fastening method. A feed pipe cover plate bracket 12 is provided on one side of the feed pipe cover plate 11. The top of the feed pipe cover bracket 12 is connected to the feed pipe cover 11 via a hinge shaft, and the bottom of the feed pipe cover bracket 12 is fastened to the side wall of the slide base plate 2 by bolts; a feed pipe cover fastening bracket 19 is provided on the other side of the feed pipe cover 11, and corresponding connecting holes are provided at the covering positions of the feed pipe cover 11 and the feed pipe cover fastening bracket 19, and bolts are installed in the connecting holes. After the feed pipe cover 11 rotates around the hinge shaft as the rotation center to cover the feed pipe cover fastening bracket 19, it is fastened by bolts; the bottom of the feed pipe cover fastening bracket 19 is fastened to the side wall of the slide base plate 2 by bolts.

[0066] Furthermore, a pressure rod 13 is hinged to the front end of the feed pipe cover plate 11, and the pressure rod 13 covers the push channel between the first baffle plate 8 and the second baffle plate 9; the feed inlet 4 corresponds to the push channel.

[0067] Furthermore, a radial ejection mechanism is connected to the slide base plate 2 at the front end of the first baffle 8 and the second baffle 9 of the transverse pushing mechanism; the radial ejection mechanism is an ejection rod 15, which is placed on the slide base plate 2. The ejection rod 15 is a cuboid structure with a groove on one side. The groove opening corresponds to the pushing channel of the transverse pushing mechanism, so that the space enclosed by the two opposite side walls and the bottom wall of the groove on the slide base plate 2 is connected to the pushing channel. The groove position of the ejection rod 15 is the nut marking groove 3; the nut is pushed along the pushing channel by the push rod 10 into the marking groove 3, and the nut is marked by the engraving head corresponding to the marking groove 3.

[0068] Furthermore, the ejector rod 15 slides radially relative to the slide rail base plate 2 via a sliding mechanism. The sliding mechanism includes: a slide rod disposed on the ejector rod 15, a rear baffle 16, and a slide rail 17 formed on the side wall of the rear baffle. A slide rod protrudes from the side wall of the ejector rod 15 in the opposite direction to the groove of the ejector rod 15. A slide rail 17 matching the slide rod is formed on the side wall of the rear baffle 16 closest to the ejector rod 15. The rear baffle 16 is fixedly connected to the slide rail base plate 2 by bolts. The ejector rod 15 can reciprocate in the slide rail 17 of the rear baffle 16 via the slide rod.

[0069] Furthermore, one end of the ejector rod 15 is the power end, which is connected to the ejector hydraulic power device, and the other end is the discharge end, which corresponds to the external slide discharge trough; after the nut is marked, the ejector rod 15 needs to slide from the power end to the discharge end to discharge the material;

[0070] The unloading process involves the unloading rod 15 disengaging from the push channel through its groove, misaligning with the push channel, and passing over the first baffle 8 located at the unloading end, so that the groove of the unloading rod 15 corresponds to the slide unloading groove.

[0071] Furthermore, the ejection hydraulic power device is an ejection hydraulic cylinder. The cylinder body of the ejection hydraulic cylinder is supported by a cylinder bracket 18. The cylinder bracket 18 has an L-shaped right-angle structure. The bottom of the cylinder bracket 18 is fixedly connected to the base plate 1 by bolts. The telescopic end of the ejection hydraulic cylinder is connected to the end of the ejection rod 15.

[0072] Furthermore, the hydraulic power unit for the transverse pushing mechanism is a pushing hydraulic cylinder. The pushing hydraulic cylinder is located in the height space between the base plate 1 and the slide base plate 2, corresponding to the area of ​​the elongated through hole 201 of the slide base plate 2. The cylinder body of the pushing hydraulic cylinder 20 is fixed to the base plate 1 by a cylinder bracket 18. A pushing rod connecting frame 21 is provided on the base plate 1 in the direction of the extension rod of the pushing hydraulic cylinder 20. A cylinder connecting sleeve 22 is provided inside the pushing rod connecting frame 21. The extension rod of the pushing hydraulic cylinder 20 is provided inside the cylinder connecting sleeve 22. The telescopic rod of the pusher hydraulic cylinder 20 is spirally connected to the cylinder connecting sleeve 22 through the matching threaded hole 221, thereby connecting with the pusher rod 10 connecting frame; the top of the pusher rod connecting frame 21 is connected to the pusher rod 10 by screws 23, and the top of the pusher rod connecting frame 21 passes through the elongated through hole 201 area of ​​the slide bottom plate 2, so that the pusher rod 10 can move together with the pusher hydraulic cylinder 20; the pusher hydraulic cylinder 20 drives the pusher rod 10 to move in the pusher channel, thereby pushing the nut that enters the pusher channel from the feed tube.

[0073] It should be noted that the end of the pressure rod 13 that is hinged to the feed tube cover plate 11 is the connecting end, and the other end is the free end; the edge of the free end of the pressure rod 13 does not exceed the groove opening of the ejector rod 15, so as to prevent the pressure rod 13 from being too long and covering the top of the groove, thereby affecting the engraving of the characters for marking.

[0074] The nut marking and loading / unloading process using the above scheme is as follows:

[0075] Nuts are fed into the device;

[0076] The nut is vibrated and fed from the vibrating plate of the feeding mechanism, enters the feeding tube, then enters the feeding port 4 and enters the pushing channel of the transverse pushing mechanism;

[0077] The equipment loads and marks the materials;

[0078] The pusher hydraulic cylinder is activated, and the pusher rod, under the power of the pusher hydraulic cylinder, pushes the nut forward along the pusher channel until it reaches the junction with the radial ejection mechanism. At this junction, the groove of the ejection rod 15 is connected to the pusher channel. The pusher rod pushes the nut into the groove of the ejection rod 15 and pushes it against the nut through the telescopic end of the pusher hydraulic cylinder. At this time, the groove of the ejection rod 15 forms the nut marking groove 3, and the marking head above the marking groove 3 moves downward to mark the nut.

[0079] Equipment feeding;

[0080] After the nut is marked, the pusher hydraulic cylinder retracts, leaving the nut in the groove of the ejector rod 15. At this time, the ejector hydraulic cylinder is activated, causing the ejector rod 15 to slide from the power end to the material end. When the groove of the ejector rod 15 is misaligned with the pusher channel and passes the end of the first baffle 8 in the direction of the material discharge of the transverse pusher mechanism, until the groove of the ejector rod 15 reappears and corresponds to the slide discharge trough 24 outside the device, the nut in the groove of the ejector rod 15 slides down from the slide discharge trough into the material box 25 by gravity, thus completing the material discharge of the device.
