Description

Technical Field

[0001] This utility model relates to the field of thread rolling machine technology, specifically to an automatic bolt feeding thread rolling machine. Background Technology

[0002] Bolts are common fasteners widely used in machinery, construction, transportation, and many other fields. Bolts, in conjunction with nuts, use threaded connections to fasten two parts with through holes together, forming a stable connection. This type of connection is detachable, facilitating maintenance and replacement. In mechanical equipment, bolts not only fix parts but also transmit power and bear loads, ensuring the safe operation of the equipment. Bolted connections can use washers and other auxiliary components to distribute pressure, reducing pressure per unit area and protecting the surfaces of the connected parts. During the bolt manufacturing process, the outer ends of the bolts need to be threaded. The purpose of thread rolling is to connect them to the nut. The principle of bolt thread rolling is that two identical thread rolling plates move relative to each other, rolling the blank into spiral grooves.

[0003] The thread rolling process for bolts is mechanized to improve processing efficiency and output. To reduce worker workload, an automatic feeding method is used to add bolts to the thread rolling machine. However, during the process of the bolts entering the feeding rod via the vibratory feeder, some bolts tilt, causing them to get stuck inside the feeding rod. This affects processing efficiency and can also lead to malfunctions and damage to the thread rolling machine. Therefore, an automatic feeding thread rolling machine is proposed, which uses a guide plate at the outer end of a belt to move the bolts inside the feeding rod to solve the above problems. Utility Model Content

[0004] This utility model proposes an automatic bolt feeding thread rolling machine, which solves the problems in related technologies where bolts tilt and get stuck inside the feeding rod, affecting the accuracy of bolt thread rolling, and skewed bolts causing malfunctions and damage to the thread rolling machine.

[0005] The technical solution of this utility model is as follows:

[0006] An automatic bolt feeding thread rolling machine includes a mounting plate, a movable plate slidably connected inside the mounting plate, a thread rolling plate being snapped into the movable plate, an extrusion plate slidably connected to the top of the mounting plate, a feeding rod fixedly connected to one side of the extrusion plate, a feeding groove inside the feeding rod, and a feeding assembly on one side of the feeding rod; the feeding assembly includes a hollow equipment plate fixedly connected to one side of the feeding rod, the feeding rod communicating with the hollow equipment plate, pulleys symmetrically rotatably connected inside the hollow equipment plate, a connecting belt sleeved between the two pulleys, a guide plate fixedly connected to the outer end of the connecting belt, and the guide plate being movably connected inside the feeding groove.

A servo motor is fixedly connected inside the motor housing, and a transmission bevel gear is fixedly connected to the output end of the servo motor. A driven bevel gear meshes with the outer end of the transmission bevel gear. Both the transmission bevel gear and the driven bevel gear are located inside the motor housing, and the driven bevel gear is fixedly connected to one of the pulleys.

[0008] Optionally, one side of the feeding trough is an arc-shaped groove, and the feeding assembly further includes an electric telescopic device fixedly connected to the outer end of the feeding rod. The telescopic part of the electric telescopic device passes through the feeding rod and is fixedly connected to an arc-shaped abutment plate, which is located inside the arc-shaped groove.

[0009] Optionally, the movable plate has a slot and a fixing strip inside, the thread rolling plate is engaged inside the slot, there are two fixing strips, and the thread rolling plate and the fixing strip are threadedly connected by fixing bolts.

[0010] Optionally, a connecting plate is fixedly connected to the back of the extrusion plate, a mounting base is fixedly connected to the outer end of the connecting plate, a sliding groove is symmetrically slidably connected to the top of the mounting plate, and a connecting leaf is symmetrically fixedly connected to the bottom end of the mounting base, the connecting leaf being slidably connected inside the sliding groove.

[0011] Optionally, a connecting rod is fixedly connected between the two connecting leaves, and a lead screw is threadedly connected to the center of the connecting rod. The bottom of the mounting plate is provided with a groove, and the lead screw is rotatably connected inside the groove.

[0013] Optionally, the outer end of the rotating wheel is rotatably connected to a mounting housing.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] In this invention, a connecting belt rotating between two pulleys causes a guide plate at the outer end of the connecting belt to move the bolt inside the feeding rod, thereby moving the bolt inside the feeding rod. While conveying the bolt, it also straightens the bolt, preventing it from becoming misaligned and stuck inside the feeding rod, which would affect the bolt processing efficiency. At the same time, the bolt correction operation can prevent the bolt from tilting and entering between the thread rolling plate and the extrusion plate, thus avoiding affecting the thread rolling accuracy and preventing misaligned bolts from causing malfunctions or damage to the thread rolling machine.

[0028] Example 1

[0029] Reference Figures 1-5This is the first embodiment of the present invention, which proposes an automatic bolt feeding type thread rolling machine, including a mounting plate 1, a movable plate 2 slidably connected inside the mounting plate 1, a thread rolling plate 3 snapped into the movable plate 2, an extrusion plate 4 slidably connected to the top of the mounting plate 1, a feeding rod 5 fixedly connected to one side of the extrusion plate 4, a feeding groove 6 provided inside the feeding rod 5, and a feeding assembly 7 provided on one side of the feeding rod 5; the feeding assembly 7 includes a cavity equipment plate 701 fixedly connected to one side of the feeding rod 5, the feeding rod 5 communicating with the cavity equipment plate 701, pulleys 702 symmetrically rotatably connected inside the cavity equipment plate 701, a connecting belt 703 sleeved between the two pulleys 702, a guide plate 704 fixedly connected to the outer end of the connecting belt 703, and the guide plate 704 being disposed inside the feeding groove 6. The purpose of this arrangement is that the bolt enters the feeding rod 5 through the vibrating plate 14, and at the same time, the two pulleys 702 drive the connecting belt 703 between them to rotate. At this time, the guide plate 704 at the outer end of the connecting belt 703 moves the bolt inside the feeding groove 6, which plays a corrective role in the process of conveying the bolt, so that the bolt is perpendicular to the feeding rod 5, and prevents the skewed bolt from getting stuck inside the feeding rod 5.

[0030] Optionally, the feed trough 6 has a T-shaped cross-section, and the feeding assembly 7 also includes a motor housing 705 fixedly connected to the bottom end of the feeding rod 5. A servo motor 706 is fixedly connected inside the motor housing 705. A transmission bevel gear 707 is fixedly connected to the output end of the servo motor 706. A driven bevel gear 708 meshes with the outer end of the transmission bevel gear 707. Both the transmission bevel gear 707 and the driven bevel gear 708 are located inside the motor housing 705. The driven bevel gear 708 is fixedly connected to one of the pulleys 702. The purpose of this arrangement is that, during the feeding process, the servo motor 706 drives the transmission bevel gear 707 to rotate, and the rotating transmission bevel gear 707 drives the driven bevel gear 708 to rotate inside the motor housing 705, thereby causing the pulley 702 connected to the driven bevel gear 708 to rotate inside the cavity equipment plate 701, thereby causing the connecting belt 703 to rotate. The T-shaped feeding groove 6 allows the bolt screw to be locked inside the feeding groove 6, with the screw head positioned above the feeding rod 5, and the bolt perpendicular to the feeding rod 5.

[0031] Optionally, one side of the feeding trough 6 is an arc-shaped groove, and the feeding assembly 7 also includes an electric telescopic device 709 fixedly connected to the outer end of the feeding rod 5. The telescopic part of the electric telescopic device 709 passes through the feeding rod 5 and is fixedly connected to an arc-shaped abutment plate 7010, which is located inside the arc-shaped groove. The purpose of this arrangement is that, during the movement of the bolt in the feeding trough 6 inside the feeding rod 5, when the bolt moves to the position of the arc-shaped groove in the feeding trough 6, the electric telescopic device 709 drives the arc-shaped abutment plate 7010 connected to its telescopic part to extend and retract, thereby conveying the bolt into the gap between the thread rolling plate 3 and the extrusion plate 4.

[0032] Example 2

[0033] Reference Figures 1-6 This is the second embodiment of the present invention, which differs from the first embodiment in that:

A fixing bolt is threadedly connected between the thread rolling plate 3 and the fixing strip. The purpose of this arrangement is that after long-term use, the outer end of the thread rolling plate 3 will experience significant wear. The thread rolling plate 3 is connected to the movable plate 2 by a snap-fit ​​method, which facilitates the replacement of the thread rolling plate 3 and reduces the maintenance cost of the thread rolling machine.

[0035] Optionally, a connecting plate 8 is fixedly connected to the back of the extrusion plate 4, and a mounting base 9 is fixedly connected to the outer end of the connecting plate 8. A slide groove 10 is symmetrically slidably connected to the top of the mounting plate 1, and a connecting leaf 11 is symmetrically fixedly connected to the bottom of the mounting base 9. The connecting leaf 11 is slidably connected inside the slide groove 10, and a connecting rod 12 is fixedly connected between the two connecting leaves 11. A lead screw 13 is threadedly connected to the center of the connecting rod 12. A groove is provided at the bottom of the mounting plate 1, and the lead screw 13 is rotatably connected inside the groove. The purpose of this arrangement is that, given the variety of bolt types and sizes, the distance between the extrusion plate 4, which can slide on the top of the mounting plate 1, and the thread rolling plate 3 can be easily adjusted as needed. During adjustment, the lead screw 13 is rotated, causing the connecting leaf 11 connected to the connecting rod 12 to move inside the slide groove 10, thereby moving the extrusion plate 4 at the top of the mounting plate 1.

[0036] Optionally, a vibratory feeder 14 is fixedly connected to one end of the feeding rod 5, and an eccentric rod 15 is rotatably connected to one end of the moving plate 2. A rotating wheel 16 is rotatably connected to one end of the eccentric rod 15. The purpose of this arrangement is that, during the processing, the rotating wheel 16 drives the eccentric rod 15 to rotate, thereby causing the moving plate 2 to reciprocate inside the mounting plate 1, thus performing thread rolling on the bolts.

[0037] Optionally, a mounting housing 17 is rotatably connected to the outer end of the rotating wheel 16. The purpose of this arrangement is that the mounting housing 17 protects the rotating wheel 16.
