Description

Technical Field

[0001] The utility model relates to the technical field of screw production equipment, in particular to a screw cross slotting machine. Background Art

[0002] A screw is a common fastener used to fasten two or more objects together. It usually has a spiral thread that can pass through a hole and screw into another pre-formed thread (such as in a nut), or screw directly into a threaded hole in another material (such as wood or plastic). One end of the screw is pointed to facilitate entry into the material, and the other end has a flat head to provide a support surface. There are notches or grooves on the top of the head to facilitate rotation with a screwdriver, wrench or other tool. During the screw production process, the screw head needs to be punched with a straight or cross-shaped blind hole.

[0003] Currently, when slotting the head of a screw, it is mostly necessary to first use a limiting structure to limit the screw to be slotted. However, before slotting the screw, the screw needs to be inserted horizontally or vertically into the placement slot of the clamp of the limiting structure. Since the diameter of the internal placement slot of the existing screw placement clamp is fixed, it is not convenient to quickly cut the material. This means that after the slotting is completed using the milling mechanism, the screws in the clamp usually need to be manually removed, which makes the overall processing efficiency low. For this reason, we propose a screw cross slotting machine. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] See also Figure 1-Figure 3 The utility model provides a technical solution: a cross slotting machine for screws, comprising a workbench 1, a PLC controller being installed on the outer wall of the workbench 1, a robotic arm 2 being installed at one end of the upper end surface of the workbench 1, and a slot milling mechanism 3 being installed at the end of the robotic arm 2. If cross slotting is difficult to achieve with one robotic arm 2, two robotic arms 2 can be provided, each robotic arm 2 corresponding to a slot milling mechanism 3, and cross slotting is achieved through the cooperation of the two slot milling mechanisms 3, wherein the slot milling mechanism 3 comprises a first motor 31 and a slot milling cutting blade 32, the first motor 31 being installed at the end of the robotic arm 2, the slot milling cutting blade 32 being installed at the output end of the first motor 31, the first motor 31 being started, and the slot milling cutting blade 32 being driven to rotate by the output end of the first motor 31 to achieve slotting of the screw head.

[0032] Secondly, see Figure 4 and Figure 6 As shown, the screw cross slotting machine also includes a guide nail seat 5 and a clamping nail assembly 6. The guide nail seat 5 is fixed to the upper end surface of the workbench 1, and a guide nail groove 51 is opened in the middle of the upper end surface of the guide nail seat 5. The clamping nail assembly 6 includes a movable supporting structure 61. The movable supporting structure 61 is used to support the head of the screw upward or release the supported screw to enter the guide nail groove 51.

[0033] Among them, in the specific implementation of this utility, refer to Figure 6 As shown, the movable supporting structure 61 includes a second motor 611 and two L-shaped bars 617. A mounting seat 4 is also fixed on the upper end surface of the workbench 1. The second motor 611 is installed in the mounting seat 4. The second motor 611 is a motor with a forward and reverse shaft, and a screw rod 612 is installed at the output end of the second motor 611. A screw nut seat 613 is installed on the outside of the screw rod 612. A first mounting bar 614 is fixed at both ends of the screw nut seat 613. A second mounting bar 615 is hinged on each first mounting bar 614. A third mounting bar 616 is hinged on the end of the second mounting bar 615 away from the first mounting bar 614. The end of each third mounting bar 616 is fixed to the end of a corresponding L-shaped bar 617, and a supporting plate 618 is fixed on the opposite side of the two L-shaped bars 617. A semicircular groove 6181 is provided on the opposite side of the two supporting plates 618.

[0034] Through the above, during specific use, the output end of the second motor 611 is first used to drive the screw 612 to rotate, so that the screw nut seat 613 moves toward one end of the second motor 611, and the inclination of the second mounting bar 615 hinged between the first mounting bar 614 and the third mounting bar 616 is changed, so that the two supporting plates 618 can be brought close to each other, and then the staff can pass the rod of the screw to be slotted through the two semicircular grooves 6181 to form a circular groove, so that the head of the screw is hung on the upper end surface of the supporting plate 618, and then the robot arm 2 and the milling mechanism 3 can be started by the PLC controller to slot the head of the screw.

[0035] After the slotting is completed, the shaft of the second motor 611 is reversed, and the screw nut seat 613 is moved toward the end away from the second motor 611, so that the two supporting plates 618 can be separated. After the separation distance is greater than the diameter of the screw head, the slotted screws can automatically fall into the guide groove 51, which makes unloading convenient and does not require manual cooperation of the staff, greatly improving the processing efficiency.

[0036] Among them, by setting the PLC controller, the forward and reverse rotation of the shaft of the second motor 611 can be achieved in an orderly interval.

[0037] In addition, see Figure 4 and Figure 6 As shown, a slider 64 is fixed to the bottom end of the L-shaped bar 617 , and sliding grooves 53 are provided on both sides of the upper end surface of the nail guide seat 5 , and the slider 64 is slidably fitted in the sliding grooves 53 .

[0038] Specifically, when the two L-shaped bars 617 move closer to or farther away from each other, the slider 64 can move along the sliding groove 53 , thereby increasing the stability of the movement of the L-shaped bars 617 .

[0039] Also, see Figure 3 and Figure 5 As shown, a guide hole 9 communicating with the nail guide groove 51 is opened on the upper end surface of the workbench 1, and a nail guide tube 8 is connected to the bottom end of the guide hole 9. A collection box 7 is provided inside the workbench 1 and below the nail guide tube 8.

[0040] As mentioned above, the screws that fall into the guide nail groove 51 can enter the guide nail tube 8 through the guide hole 9, and then fall from the guide nail tube 8 into the collection box 7 for collection, which is more convenient and practical. After a certain amount of screws are collected in the collection box 7, the staff can pull out the collection box 7 to replace the collection box 7.

[0041] A foam pad may be provided at the bottom of the collecting box 7 to provide a buffer after the screw falls, thereby improving protection and reducing noise caused by collision.

[0042] Example 2

[0043] The difference between this embodiment and the first embodiment is that, see Figure 6 As shown, the clamping nail assembly 6 also includes a tightening structure 63, which is arranged below the movable supporting structure 61 and can move synchronously with the movable supporting structure 61, and a telescopic member 62 is installed between the tightening structure 63 and the movable supporting structure 61, and the telescopic member 62 is an electric telescopic rod or a pneumatic telescopic rod.

[0044] Among them, the tightening structure 63 includes a connecting strip 631 and a clamping strip 632. The connecting strip 631 is fixed to the bottom end of the telescopic member 62, and the clamping strip 632 is fixed to the side of the connecting strip 631 facing the guide nail groove 51, and the clamping surface of the clamping strip 632 is evenly fixed with anti-slip protrusions.

[0045] See Figure 4 As shown, grooves 52 for accommodating the pressing structure 63 to enter and exit are symmetrically formed on both sides of the nail guide seat 5 , and the grooves 52 are connected to the nail guide grooves 51 .

[0046] Through the above, when the screw to be slotted is placed between the two supporting plates 618, the clamping strip 632 fixed with the anti-slip protrusion can press the lower end of the screw from both sides, thereby improving the stability of the screw and reducing the occurrence of screw skew during the slotting process.

[0047] The telescopic member 62 is used to adjust the raising and lowering of the clamping strip 632 , and the height of the clamping strip 632 can be adjusted according to screws of different lengths to press and limit the lower end of the screw, which is more flexible.
