[0002] Traditional screw machine applications generally lack efficient screw storage and automatic feeding mechanisms, resulting in a reliance on manual loading of screws one by one. This operating mode is not only inefficient but also significantly increases labor costs. After the screw machine completes a screw, the operator must immediately manually place the next screw into the machine's feed port. This process is time-consuming and labor-intensive, leading to the development of a screw machine with a storage mechanism. Summary of the Invention

[0003] The object of the present invention is to provide a screw machine with a storage structure to solve the problems raised in the above background technology.

[0005] A placement box is provided on one side of the main sleeve, a screw clamp for arranging screws in a straight line is detachably installed inside the placement box, and a pressing component for pressing the screws in the screw clamp downward is provided on the placement box;

[0006] A housing is connected between the main sleeve and the lower end of the placement box. A rotating wheel is rotatably connected to the interior of the housing. The rotating wheel is shaped like a frustum. The angle between the rotating axis of the rotating wheel and the center line of the main sleeve is 45 degrees. A plurality of slots for storing screws are evenly arranged on the side wall of the rotating wheel.

[0007] When the rotating wheel rotates, multiple material grooves are aligned with the lower end of the screw clamp and the inner cavity of the main sleeve in sequence. The material grooves aligned with the lower end of the screw clamp are horizontal, and the material grooves aligned with the inner cavity of the main sleeve are vertical.

[0008] Preferably, the screw clamp is provided with an open slot, which is opened along the length direction of the screw clamp and is open above the open slot. The pressing assembly includes two guide rods and a pressing block. The two guide rods are respectively fixed on both sides of the placement box. The pressing block is horizontally placed inside the placement box. Both ends of the pressing block pass through the side walls of the placement box and are respectively slidably sleeved on the two guide rods, and the two guide rods are sleeved with a second spring for pressing the pressing block downward.

[0009] When the screw clamp is installed inside the placement box, the pressing block slides in from above the opening slot and is pressed onto the uppermost screw of the screw clamp.

[0010] Preferably, the lower end of the screw clamp is open, and a baffle capable of blocking the lower end of the screw clamp is laterally inserted into the lower end of the screw clamp.

[0011] Preferably, two blocks are symmetrically provided at the lower end of the main sleeve, and a third spring is provided at the lower end of the main sleeve for pressing the two blocks toward the middle. Through holes are provided on the opposite surfaces of the two blocks for allowing the threaded ends of the screws to pass through, and inclined walls are provided above the opposite surfaces of the two blocks. When the opposite surfaces of the two blocks are pressed tightly, the inclined walls on the two blocks form a V-shaped groove.

[0012] Preferably, the sliding sleeve is connected to the lower end of the screw machine body through threaded engagement.

[0013] Preferably, a plurality of limiting blocks are provided on the inner side wall of the main sleeve, and limiting grooves adapted to the limiting blocks are opened on the outer wall of the sliding sleeve.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0028] See also Figure 1-9 The present invention provides a technical solution: a screw machine with a storage structure, comprising a main sleeve 1, the upper end of the main sleeve 1 is slidably connected to a sliding sleeve 3 through a first spring 2, such as Figure 2 As shown, the first spring 2 is arranged inside the upper end of the main sleeve 1, and the lower end of the sliding sleeve 3 is inserted into the interior of the main sleeve 1 and abuts against the first spring 2. When the sliding sleeve 3 slides downward on the main sleeve 1, the sliding sleeve 3 compresses the first spring 2 to slide. At this time, the first spring 2 provides an elastic force to reset the sliding sleeve 3 to slide upward. The upper end of the sliding sleeve 3 is installed on the head of the screw machine body 4. The tool rod of the screw machine body 4 passes through the sliding sleeve 3 and extends to the interior of the main sleeve 1;

[0029] A placement box 5 is provided on one side of the main sleeve 1. A screw clamp 6 for arranging screws in a straight line is detachably installed inside the placement box 5. A pressing component 7 for pressing the screws in the screw clamp 6 downward is provided on the placement box 5.

[0030] like Figure 2-4 As shown, in order to be able to sequentially transport the screws in the screw clamp 6 to the interior of the main sleeve 1 to achieve continuous screwing operation,

[0031] A housing 8 is connected between the main sleeve 1 and the lower end of the placement box 5, and a rotating wheel 9 is rotatably connected inside the housing 8. Figure 2 and 3As shown, the shape of the rotating wheel 9 is a frustum, and the angle between the rotating axis of the rotating wheel 9 and the center line of the main sleeve 1 is 45 degrees. A plurality of material slots 901 for storing a screw are evenly opened on the side wall of the rotating wheel 9;

[0032] When the rotating wheel 9 rotates, the multiple troughs 901 are aligned with the lower end of the screw clamp 6 and the inner cavity of the main sleeve 1 in sequence. The troughs 901 aligned with the lower end of the screw clamp 6 are horizontal, and the troughs 901 aligned with the inner cavity of the main sleeve 1 are vertical.

[0033] When the rotating wheel 9 rotates, a material trough 901 is aligned with the lower end of the screw clamp 6. At this time, the lowest screw in the screw clamp 6 falls into the inside of the material trough 901. As the rotating wheel 9 rotates, the screw in the material trough 901 will gradually be transported to the inside of the main sleeve 1, that is, transported to the bottom of the cutter head of the screw machine body 4. As the screw machine body 4 and the sliding sleeve 3 slide downward, the end of the cutter head docks with the head of the screw, and then the screw is pushed into the main sleeve 1 and the rotation of the cutter head is used to realize the operation of screwing.

[0034] Combine Figure 2-5 as well as Figure 9 As shown, in order to enable the rotation of the rotating wheel 9 to be linked with the sliding of the screw machine body 4 and the sliding sleeve 3 on the main sleeve 1, a rotating rod 17 is provided on the side wall of the main sleeve 1. The axis of the rotating rod 17 is parallel to the axis of the main sleeve 1. The lower end of the rotating rod 17 is connected to the rotating shaft of the rotating wheel 9 through a universal joint 19. When the rotating rod 17 rotates, the rotating rod 17 rotates synchronously with the rotating wheel 9. The side wall of the rotating rod 17 is circumferentially distributed with vertical grooves equal to the number of the material troughs 901. Grooves 1701, multiple vertical grooves 1701 are parallel to the axis of the rotating rod 17. A V-shaped groove is provided at the upper end of each vertical groove 1701 and located on the rotating rod 17. The V-shaped groove includes a first oblique groove 1702 and a second oblique groove 1703. The first vertical groove 1701 is connected to the lower ends of the first oblique groove 1702 and the second oblique groove 1703. On two adjacent V-shaped grooves, the upper ends of the first oblique groove 1702 and the upper ends of the second oblique groove 1703 are connected to form a continuous M shape.

[0035] A linkage rod 18 is fixed to the lower end of the sliding sleeve 3, and a toggle column 1801 is provided on one side of the linkage rod 18. Figure 5 As shown, a fourth spring 1802 is provided on the toggle post 1801 so that its length can be axially extended and retracted. The toggle post 1801 is slidably connected between the first vertical groove 1701 and the V-shaped groove;

[0036] like Figure 9 As shown, in order to make the toggle post 1801 move along the first vertical groove 1701 and the V-shaped groove Figure 9When the arrow shown slides, that is, after the sliding sleeve 3 slides up and down once, the toggle post 1801 moves from the hollow circle to the first vertical groove 1701 and the V-shaped groove along the Figure 9 When the arrow shown slides to the solid arrow (the hollow circle and the solid circle represent the toggle post 1801 in different positions), the groove depth of the first inclined groove 1702 gradually becomes shallower from top to bottom, and a step is formed at the connection between the first inclined groove 1702 and the first vertical groove 1701. The groove depth of the second inclined groove 1703 gradually becomes shallower from bottom to top, and the connection between the second inclined groove 1703 and the first vertical groove 1701 is a smooth transition, and a step is formed at the connection between the second inclined groove 1703 and the first inclined groove 1702.

[0037] When the sliding sleeve 3 slides downward, a step is formed at the connection between the second inclined groove 1703 and the first inclined groove 1702, so that the toggle post 1801 slides downward along the first inclined groove 1702, so that the toggle post 1801 can slide from the first inclined groove 1702 into the first vertical groove 1701;

[0038] When the sliding sleeve 3 slides upward, the toggle post 1801 slides upward. Since a step is formed at the connection between the first inclined groove 1702 and the first vertical groove 1701, the toggle post 1801 slides from the first vertical groove 1701 into the interior of the second inclined groove 1703, passes through the second inclined groove 1703 and reaches the connection between the first inclined groove 1702 and the second inclined groove 1703.

[0039] The linkage process is:

[0040] In the natural state, the first spring 2 is in a state of upwardly pressing the sliding sleeve 3. At this time, the toggle column 1801 is at the connection position of the first oblique groove 1702 and the second oblique groove 1703. When the toggle column 1801 slides downward along the first oblique groove 1702 to the connection between the first oblique groove 1702 and the first vertical groove 1701, a material groove 901 is just opposite to the inner cavity of the main sleeve 1. The sliding sleeve 3 continues to slide downward, and the toggle column 1801 slides in the first vertical groove 1701. At this time, the screw machine body 4 screws a screw. After the operation is completed, the sliding sleeve 3 slides upward. At this time, the toggle column 1801 slides upward along the first vertical groove 1701 and the second oblique groove 1703 to reset to the connection between the next first oblique groove 1702 and the second oblique groove 1703. In the second oblique groove 1703, the toggle column 1801 cooperates with the second oblique groove 1703 to drive the rotating rod 17 and the rotating wheel 9 to rotate a certain angle. When the sliding sleeve 3 is pressed downward again, the screw in the next material trough 901 is screwed, and the cycle is repeated.

[0041] like Figure 6-8 As shown, in order to be able to push the screws out from the lower end of the screw clamp 6 in sequence, specifically, the screw clamp 6 is provided with an open slot 601, as shown in FIG. Figure 6-8As shown, the open slot 601 is opened along the length direction of the screw clamp 6, and the upper part of the open slot 601 is open. The pressing assembly 7 includes two guide rods 701 and a pressing block 703. The two guide rods 701 are respectively fixed on both sides of the placement box 5. The pressing block 703 is horizontally placed inside the placement box 5. Both ends of the pressing block 703 pass through the side walls of the placement box 5 and are respectively slidably connected to the two guide rods 701. The two guide rods 701 are both connected with a second spring 702 for pressing the pressing block 703 downward.

[0042] When the screw clamp 6 is installed inside the placement box 5, the lower pressing block 703 slides in from above the opening slot 601 and presses onto the uppermost screw of the screw clamp 6;

[0043] When the screw clamp 6 is installed in the placement box 5, the lower pressing block 703 is pushed upward. At this time, the lower pressing block 703 compresses the second spring 702 and slides upward along the guide rod 701. In this state, the screw clamp 6 is placed in the placement box 5. When the screw clamp 6 is installed in place, the lower pressing block 703 is just above the opening slot 601. Then the lower pressing block 703 is released. At this time, the lower pressing block 703 is pressed by the second spring 702, and the lower pressing block 703 slides downward along the guide rod 701, causing the lower pressing block 703 to slide to the inside of the opening slot 601, and then the lower pressing block 703 is pressed on the uppermost screw of the screw clamp 6. At this time, the lower pressing block 703 presses the screw in the screw clamp 6 downward;

[0044] In addition, with the cooperation between the pressing block 703 and the opening slot 601 , the screw clip 6 can be fixed inside the placement box 5 .

[0045] like Figure 6-8 As shown, a notch is provided on one side of the upper end of the screw clamp 6 , which is beneficial for avoiding the lower pressing block 703 when the screw clamp 6 is installed into the interior of the placement box 5 , so that the lower pressing block 703 can be located directly above the opening slot 601 .

[0046] like Figure 7-8 As shown, in order to facilitate the placement of the screws into the interior of the screw clamp 6, specifically, the lower end of the screw clamp 6 is open, and the lower end of the screw clamp 6 is laterally plugged with a baffle 602 that can block the lower end of the screw clamp 6. When the screw is placed into the screw clamp 6, the baffle 602 is plugged into the lower end of the screw clamp 6. At this time, the lower end opening of the screw clamp 6 is blocked by the lower end of the screw clamp 6, which is conducive to the arrangement of the screws inside the screw clamp 6. After the screw clamp 6 is installed into the placement box 5, the baffle 602 is pulled out from the lower end of the screw clamp 6. At this time, the lower end opening of the screw clamp 6 is opened, and the screws inside it will be guided out of the screw clamp 6 from bottom to top.

[0047] like Figure 4As shown, in order to prevent the screws delivered to the inside of the main sleeve 1 from automatically falling out of the inside of the main sleeve 1, specifically, two blocks 10 are symmetrically provided at the lower end of the main sleeve 1, and a third spring 11 is provided at the lower end of the main sleeve 1 for pressing the two blocks 10 toward the middle. Through holes are provided on the opposite surfaces of the two blocks 10 for allowing the threaded ends of the screws to pass through, and inclined walls are provided above the opposite surfaces of the two blocks 10. When the opposite surfaces of the two blocks 10 are pressed tightly, the inclined walls on the two blocks 10 form a V-shaped groove.

[0048] like Figure 4 As shown, when the screw is delivered to the interior of the main sleeve 1, the threaded end of the screw is located at the lower end, and the main sleeve 1 is in Figure 4 In the state shown, the screw slides down, and the threaded end of the screw can pass through the through hole between the two blocks 10, and the upper end of the screw rests on the two inclined walls, thereby preventing the screw from automatically falling out of the inside of the main sleeve 1; as the screw machine body 4 slides downward, the cutter head of the screw machine body 4 presses the screw downward, and the upper end of the screw squeezes the two blocks 10 to both sides, and the screw can be pushed out by the cutter head, realizing the screw driving operation.

[0049] like Figure 5 As shown, in order to fix the screw machine body 4 and the sliding sleeve 3 together, specifically, the sliding sleeve 3 is connected to the lower end of the screw machine body 4 through threaded engagement.

[0050] like Figure 1-3 As shown, in order to ensure that the angle between the sliding sleeve 3 and the main sleeve 1 remains unchanged and prevent the sliding sleeve 3 from rotating on the main sleeve 1, specifically, a plurality of limiting blocks 13 are provided on the inner side wall of the main sleeve 1, and limiting grooves 14 adapted to the limiting blocks 13 are opened on the outer wall of the sliding sleeve 3. When the sliding sleeve 3 is installed inside the main sleeve 1, the limiting blocks 13 are located inside the corresponding limiting grooves 14.

[0051] like Figure 1-3 As shown, in order to stably install the sliding sleeve 3 inside the main sleeve 1, specifically, an anti-slip block 15 is provided at the lower end of the limiting block 13, and a bolt 16 is provided on the side wall of the main sleeve 1. The threaded end of the bolt 16 passes through the limiting block 13 and extends to the inside of the limiting groove 14. After the sliding sleeve 3 is installed inside the main sleeve 1, the bolt 16 is screwed onto the main sleeve 1, and the threaded end of the bolt 16 is inside the limiting groove 14. When the sliding sleeve 3 slides upward, the anti-slip block 15 limits the bolt 16 from sliding out of the limiting groove 14. With the cooperation of the anti-slip block 15 and the bolt 16, the sliding sleeve 3 can be stably installed in the main sleeve 1.

[0052] like Figure 1As shown, in order to increase the stability of the placement box 5 installed on the main sleeve 1, specifically, a hoop 12 is provided at the upper end of the placement box 5, and the hoop 12 is fixedly sleeved on the side wall of the main sleeve 1.

[0053] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
