Technical Field
[0001] The utility model relates to the field of feeding devices, and particularly relates to a feeding and discharging device for an automatic thread rolling machine. Background Art
[0002] The thread processing of fasteners such as bolts and screws is usually completed by thread rolling or thread rolling. For smaller-sized threads, thread rolling is mostly used, while for relatively larger-sized threads with higher thread quality requirements, thread rolling processing is mostly used. The thread rolling machine positions the rod-shaped workpiece to be processed through a center rest, and two thread rolling wheels on both sides of the center rest roll and extrude the workpiece to form threads on the workpiece surface. In the prior art, the feeding of the thread rolling machine is manually operated one by one, and the discharging is also one by one after processing, with low efficiency and potential safety hazards. Although there are many vibrating bowl feeding methods in the prior art, they are not directly applicable to the thread rolling machine. Therefore, improving the feeding and discharging efficiency of the thread rolling machine in the prior art is an urgent problem to be solved. Summary of the Utility Model
[0003] The utility model aims to provide a feeding and discharging device for an automatic thread rolling machine to solve the problems of low efficiency of manual feeding and discharging of the thread rolling machine and the lack of feeding equipment suitable for the thread rolling machine in the prior art.
[0004] To achieve the above object, the utility model adopts the following technical scheme: A feeding and discharging device for an automatic thread rolling machine includes a frame, on which a feeding mechanism and a discharging mechanism are installed. The feeding mechanism includes an inclined feeding trough, at the low end of the feeding trough, there are two side-by-side retaining bars, above the retaining bars, there is a feeding conveyor belt, the conveying direction of the feeding conveyor belt is the same as the arrangement direction of the retaining bars, a vertically liftable feeding gripper is connected to the feeding conveyor belt, and the feeding gripper is used for clamping the material between the retaining bars; below the retaining bars, there is a discharging air cylinder rod parallel to the feeding conveyor belt, and the telescopic end of the discharging air cylinder rod is connected with a discharging gripper, and the discharging gripper is used for pulling out the processed material from the thread rolling machine.
[0005] Preferably, as an improvement, a vertical lifting air cylinder is connected to the feeding conveyor belt, the telescopic end of the vertical lifting air cylinder is arranged downward and is installed with a support block, the feeding gripper is a pneumatic gripper horizontally installed on the support block, the feeding gripper includes two L-shaped clamping rods, the vertical sections of the clamping rods are arranged downward, and the width of the vertical sections of the clamping rods is less than the distance between the two retaining bars.
[0006] Preferably, as an improvement, the discharging gripper is a horizontal pneumatic gripper, the discharging gripper includes two L-shaped clamping plates, the short sides of the two clamping plates face each other, and a semi-circular groove is arranged in the middle of the short sides.
[0007] Preferably, as an improvement, a horizontal limiting rod is arranged on the discharging gripper, and the limiting rod extends into the space between the two clamping plates.
[0008] The principle and advantages of this solution are as follows: In actual application, the frame is placed at the side end of the thread rolling machine as a support structure. The high end of the feeding chute is docked with the discharging end of the vibrating feeding tray, so that the smooth-shank bolts slide into the feeding chute in the posture with the smooth-shank end facing the thread rolling machine, and are blocked by the blocking rod at the low end of the feeding chute and then maintain the posture with the smooth-shank end facing the thread rolling machine. The feeding conveyor belt provides the power and guidance for the horizontal translation of the vertical lifting cylinder and the feeding gripper. The vertical lifting cylinder provides the power and guidance for the vertical lifting of the feeding gripper, so that the feeding gripper can translate within the vertical plane where the feeding conveyor belt and the vertical lifting cylinder are located. The two L-shaped clamping rods of the feeding gripper can avoid the blocking rod and prevent interference between the feeding gripper and the blocking rod, the frame and the feeding chute. The vertical section of the clamping rod clamps the smooth-shank bolt at the blocking rod and then translates it to the center rest of the thread rolling machine, and then the feeding gripper resets. During this process, the movement of the feeding conveyor belt is a reciprocating movement. After the smooth-shank bolts are thread-rolled in the thread rolling machine, the rod of the discharging cylinder extends to move the discharging gripper towards the center rest of the thread rolling machine. The discharging gripper remains in an open posture. When the rod of the discharging cylinder reaches the end of its extending stroke, the limiting rod on the discharging gripper contacts the head of the processed bolt in the thread rolling machine. The discharging gripper acts, and the two clamping plates clamp the neck of the bolt from both sides. The rod part of the bolt is clamped by the semi-circular grooves on the two clamping plates, so that the head of the bolt is located inside the two clamping plates. During the reset process of the rod of the discharging cylinder, the clamping plates pull the bolt out of the center rest. After the bolt disengages from the thread rolling machine, the discharging gripper resets and releases the clamping of the bolt, and the bolt falls into the receiving frame placed below. In this way, the feeding and discharging operations of the thread rolling machine can be completed through the mechanical structure, continuous processing can be carried out, the efficiency is greatly improved compared with manual feeding and discharging, and the potential safety hazards existing in manual operation are avoided, solving the problems of low efficiency of manual feeding and discharging of thread rolling machines and the lack of feeding equipment suitable for thread rolling machines in the prior art.

[0013] The following is a further detailed description through specific embodiments:
[0014] The figure marks in the drawings of the specification include: frame 1, thread rolling machine 2, feeding trough 3, stop rod 4, feeding conveyor belt 5, drive motor 6, vertical lifting cylinder 7, feeding clamp 8, clamp rod 9, unloading cylinder rod 10, unloading clamp 11, clamp plate 12, support plate 13, limit bolt 14, groove 15.
[0015] The embodiment is basically as shown in the attached Figure 1 As shown: a loading and unloading device of an automatic thread rolling machine, comprising a frame 1, on which a loading mechanism and a unloading mechanism are mounted, the loading mechanism comprising a loading trough 3 welded on the frame 1 and arranged obliquely, Figure 2 As shown, two side-by-side baffles 4 are welded on the bottom plate of the lower end of the feeding trough 3. A feeding conveyor belt 5 is installed on the frame 1 above the baffle 4 through a bearing. The driving shaft and driven shaft of the feeding conveyor belt 5 are both arranged vertically. The driving shaft of the feeding conveyor belt 5 is keyed to a driving motor 6. The driving motor 6 adopts a bidirectional motor such as a stepping motor and a servo motor sold on the market to realize the reciprocating operation of the feeding conveyor belt 5. The conveying direction of the feeding conveyor belt 5 is the same as the arrangement direction of the baffle 4. A vertical lifting cylinder 7 is bolted to the feeding conveyor belt 5. The telescopic end of the vertical lifting cylinder 7 is arranged downward and a support block is threadedly installed. A horizontal feeding clamp 8 is bolted to the support block. The feeding clamp 8 adopts a pneumatic clamp. The feeding clamp 8 includes two L-shaped clamp rods 9. The vertical section of the clamp rod 9 is arranged downward. The width of the vertical section of the clamp rod 9 is less than the distance between the two baffle rods 4. The two clamp rods 9 of the feeding clamp 8 are used to clamp the material between the baffle rods 4. The frame 1 below the stop bar 4 is bolted with a feed cylinder rod 10 parallel to the feed conveyor belt 5. Figure 3 As shown, the telescopic end of the blanking cylinder rod 10 is threadedly connected with a blanking clamp 11, which is a horizontal pneumatic clamp. The blanking clamp 11 includes two L-shaped clamps 12, which are combined with Figure 4 As shown, the short sides of the two clamping plates 12 are opposite, and a semicircular groove 15 is provided in the middle of the short sides. The unloading clamping jaw 11 is used to pull out the processed material in the thread rolling machine 2. A vertical support plate 13 is welded on the unloading clamping jaw 11, and a horizontal limit bolt 14 is threadedly connected to the support plate 13, and the tail end of the limit bolt 14 extends between the two clamping plates 12.
[0016] The specific implementation process is as follows: The frame 1 is placed at the side end of the thread rolling machine 2 as a support structure. The high end of the feeding chute 3 is butted against the discharging end of a conventional vibrating feeding tray, so that the smooth-shank bolts slide into the feeding chute 3 in a posture with the smooth-shank end facing the thread rolling machine 2, and maintain the posture with the smooth-shank end facing the thread rolling machine 2 after being blocked by the stop bar 4 at the low end of the feeding chute 3. The vibrating feeding tray is a product of the prior art and is only used to convey a batch of smooth-shank bolts to the feeding chute 3 in a specific posture. This is the prior art and does not interfere with the subsequent loading and unloading operations of this solution, so it will not be elaborated here. The feeding conveyor belt 5 provides the power and guidance for the lateral translation of the vertical lifting cylinder 7 and the feeding gripper 8. Driven by the bidirectional motor, the feeding conveyor belt 5 can drive the vertical lifting cylinder 7 and the feeding gripper 8 to move horizontally back and forth. The vertical lifting cylinder 7 provides the power and guidance for the vertical lifting of the feeding gripper 8, so that the feeding gripper 8 can translate within the vertical plane where the feeding conveyor belt 5 and the vertical lifting cylinder 7 are located. The two L-shaped clamping rods 9 of the feeding gripper 8 can avoid the stop bar 4 to prevent interference between the feeding gripper 8 and the stop bar 4, the frame 1 and the feeding chute 3. The feeding conveyor belt 5 and the vertical lifting cylinder 7 act to move the feeding gripper 8 to the low end of the feeding chute 3. The vertical section of the clamping rod 9 of the feeding gripper 8 clamps the smooth-shank bolt at the stop bar 4 and then translates it to the center rest of the thread rolling machine 2, and then the feeding gripper 8 resets. During this process, the movement of the feeding conveyor belt 5 is a reciprocating movement. After the smooth-shank bolts are thread-rolled in the thread rolling machine 2, the blanking cylinder rod 10 extends to move the blanking gripper 11 towards the center rest of the thread rolling machine 2. The blanking gripper 11 remains in an open posture. When the blanking cylinder rod 10 reaches the end of its extending stroke, the limit bolt 14 on the blanking gripper 11 contacts the head of the processed bolt in the thread rolling machine 2. This process can be achieved by pre-adjusting the screwing-in length of the limit bolt 14 on the support plate 13. The blanking gripper 11 acts to clamp the neck of the processed bolt from both sides by the two clamping plates 12. The rod part of the bolt is clamped by the semi-circular grooves 15 on the two clamping plates 12, so that the head of the bolt is located inside the two clamping plates 12. During the reset process of the blanking cylinder rod 10, the clamping plates 12 pull the bolt out of the center rest. After the bolt is separated from the thread rolling machine 2, the blanking gripper 11 resets and releases the clamping of the bolt, and the bolt falls into the receiving frame placed below. In this way, the loading and unloading operations of the thread rolling machine 2 can be completed through the mechanical structure, and continuous processing can be carried out. The efficiency is greatly improved compared with the manual loading and unloading operation, and the potential safety hazards existing in the manual operation are avoided, solving the problems of low efficiency of manual loading and unloading of the thread rolling machine 2 and the lack of a feeding device suitable for the thread rolling machine 2 in the prior art.

It should be noted that for those skilled in the art, without departing from the technical solution of the present utility model, several deformations and improvements can be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicability of the patent.
