DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 7 As shown, the utility model provides the following technical solutions:

[0028] A lathe for processing nuts, comprising a conveying member 1 for conveying nuts along a preset path and a material guide member 3 for conveying nuts to the conveying member 1, wherein the conveying member 1 comprises at least two transmission rollers 12 rotating along a horizontal axis, and a conveyor belt 14 is sleeved between at least two transmission rollers 12;

[0029] The outer circumference of the conveyor belt 14 is sunken one by one along its length direction to form a plurality of positioning holes 15, and the positioning holes 15 are fixedly connected with positioning rods 16 inside. The top of the guide member 3 is open to form a cavity for storing nuts, and the bottom of the guide member 3 forms a discharge hole 33 matching the positioning hole 15, and the discharge hole 33 is connected to the cavity;

[0030] The lathe further comprises a tapping member 2 for tapping the nut, and the tapping member 2 is located above the conveyor belt 14 .

[0031] Through the above technical scheme, when personnel need to process nuts, the nuts are added to the guide member 3. After the nuts are added, the transmission roller 12 works, and then the transmission roller 12 drives the conveyor belt 14 to move. When the conveyor belt 14 moves, the nuts are guided to move by the guide member 3, so that the nuts fall one by one into the positioning holes 15 on the conveyor belt 14, and the nuts are positioned by the positioning rods 16 in the positioning holes 15. After the nuts fall into the positioning holes 15, the nuts are driven to continue to move forward by the conveyor belt 14, so that the nuts move to the bottom of the tapping member 2, and the nuts are tapped by the tapping member 2, so that threads are generated on the nuts.

[0032] In addition, in the present utility model, the technical solution of the conveying member 1 is further refined:

[0033] like Figure 1-Figure 3 and Figure 6 As shown, the conveying member 1 further includes a mounting frame 17 , the top of the mounting frame 17 is open to form a mounting groove 18 , and the driving roller 12 is rotatably connected to the inside of the mounting groove 18 .

[0034] In this embodiment, when personnel need to process nuts, the nuts are added to the guide member 3. After the nuts are added, the drive roller 12 is supported by the mounting groove 18 on the mounting frame 17, and the conveyor belt 14 is driven to move by the drive roller 12. When the conveyor belt 14 moves, the nut is guided to move by the guide member 3, so that the nuts fall one by one into the positioning holes 15 on the conveyor belt 14, and the nuts are positioned by the positioning rods 16 in the positioning holes 15. After the nuts fall into the positioning holes 15, the nuts are driven to continue to move forward by the conveyor belt 14, so that the nuts move to the bottom of the tapping member 2, and the nut is tapped by the tapping member 2, so that threads are generated on the nut.

[0035] Regarding how the transmission roller 12 rotates, Figure 1-Figure 3 and Figure 6As shown, the first motor 11 is fixedly connected to the mounting frame 17 , and the output end of the first motor 11 is connected to the driving roller 12 .

[0036] In this embodiment, when a person needs to drive the transmission roller 12 to rotate, the first motor 11 is operated, and then the first motor 11 drives the transmission roller 12 to rotate, and the transmission roller 12 drives the conveyor belt 14 to move.

[0037] In addition, in the present invention, in order to be able to process more nuts, such as Figure 1-Figure 3 and Figure 6 As shown, at least three partitions 13 are sleeved on the circumference of the driving roller 12 , and the conveyor belt 14 is sleeved between two adjacent partitions 13 .

[0038] In this embodiment, the partition 13 is supported by the driving roller 12, and the conveyor belt 14 is supported by two adjacent partitions 13. By adjusting the number of conveyor belts 14, the number of nuts to be processed simultaneously can be adjusted.

[0039] Specifically, in one embodiment, regarding the above-mentioned tapping member 2:

[0040] like Figure 1-Figure 2 , Figure 5 As shown, the tapping member 2 includes a base frame 25, the base frame 25 is fixedly connected to the top of the mounting frame 17, and an electric push rod 23 is fixedly connected above the base frame 25;

[0041] The telescopic end of the electric push rod 23 is connected to a connecting plate 24 , the bottom of the connecting plate 24 is fixedly connected to a second motor 22 , and the output end of the second motor 22 is connected to a tapping head 21 .

[0042] In this embodiment, when the conveyor belt 14 drives the nut to move below the tapping part 2, the connecting plate 24 is driven to move by the electric push rod 23, so that the connecting plate 24 drives the second motor 22 and the tapping head 21 to move downward until the tapping head 21 contacts the nut, and the tapping head 21 is driven to rotate by the second motor 22, and the second motor 22 and the tapping head 21 are driven to move downward synchronously by the electric push rod 23, so that the tapping head 21 taps the nut.

[0043] Specifically, in one embodiment, regarding the material guide member 3:

[0044] like Figure 1-Figure 2 , Figure 4 , Figure 7 As shown, the material guide member 3 includes a material guide cover 31 , which is fixedly connected to the top of the mounting frame 17 , and a material guide cavity 32 is formed inside the material guide cavity 32 , and a material discharge hole 33 is opened at the bottom of the material guide cover 31 .

[0045] In this embodiment, when personnel need to add nuts, the nuts are added to the material guide cavity 32 inside the material guide cover 31. After the nuts are added to the material guide cavity 32, the nuts are guided by the material guide cavity 32 so that the nuts fall through the discharge hole 33 on the material guide cover 31 into the positioning hole 15 on the conveyor belt 14, thereby completing the loading of the nuts.

[0046] In order to prevent the nuts from accumulating in the guide cavity 32, the nuts can be discharged from the discharge hole 33 more quickly. Figure 7 As shown, the inner wall of the material guiding cavity 32 is inclined downward from the side away from the material discharging hole 33 to the side close to the material discharging hole 33 to form a material guiding slope 34.

[0047] In this embodiment, when the nut in the material guiding cavity 32 moves, the material guiding slope 34 cooperates to enable the nut to move toward the discharge hole 33, thereby preventing the nut from accumulating in the material guiding cavity 32 and improving the feeding efficiency of the nut.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
