Description

Technical Field

[0001] The invention relates to a screw cutting and outputting integrated mechanism, belonging to the technical field of mechanical equipment manufacturing. Background Art

[0002] With the continuous advancement of the manufacturing industry, the demand for equipment automation is getting higher and higher. For the screw supply and tightening process, which consumes a lot of manpower and is difficult to control quality, the demand for automated applications is also very obvious. And precisely because screws are widely used in various products, the efficiency and stability of screw feeding are particularly important in the application of automatic nail feeding. The cutting and blowing of screws after sorting is an important link in screw feeding technology, and it is also the link that tests the stability and efficiency of feeding the most.

[0003] In the existing screw cutting mechanisms on the market, nail cutting and blowing occur at two different positions. After the nail cutting is completed, the screw needs to be moved to another nail blowing hole, and then the nail can be blown; the screw moves a long distance, and the cutting position is the screw head. For longer screws, the screws are prone to skew during the fast nail cutting process and cannot fall smoothly into the nail blowing hole; for thin-head screws, the screw heads are prone to get stuck in the gap between the cutting parts. As a result, the screw cutting block is designed in a block shape, usually connected to the end of the vibration plate. Due to vibration, the screw posture is not necessarily vertical, and the block-shaped cutting block is prone to squeeze the screw during rapid movement, resulting in nail jamming. Therefore, the nail cutting speed and efficiency cannot be improved. To sum up, these methods have the following main shortcomings:

[0004] 1. The screw displacement is large during the screw cutting process, and the nail cutting efficiency is low;

[0005] 2. The cutting drive position is the screw head, and long screws are prone to skew when cut;

[0006] 3. The cutting drive position is the screw head. When cutting thin-head screws, the screw head is prone to get stuck in the gap between the cutting parts.

[0007] 4. The nail cutting block can easily squeeze the screws, causing the screws to get stuck.

[0008] In summary, for the automated assembly of large numbers of screws, a special structure of integrated screw cutting and output mechanism is particularly needed to solve this problem, so as to further improve the assembly quality of the product. Summary of the invention

[0009] Purpose of the invention: In order to solve the above-mentioned problems, the present invention provides an integrated screw cutting and output mechanism.

[0010] Invention content: A screw cutting and output integrated mechanism, including a protective cover, a blowing block, a base, and a cutting mechanism. The top of the base is connected to the blowing block. The blowing block includes a blowing seat and a throttle valve. The blowing seat is connected to the throttle valve. A protective cover is installed on the outside of the base, and the base is connected to the cutting mechanism.

[0011] The cutting mechanism includes a screw cutter, a guide rail piece, a conveyed screw, a cutting cylinder, an external conveying guide rail, a fixed seat, and a material receiving baffle. The left and right sides of the cutting cylinder are respectively connected to the material receiving baffle and the screw cutter through connecting blocks. A fixed seat is installed under the screw cutter, and a guide rail piece is installed on the top outer surface of the fixed seat. The guide rail piece is connected to the external conveying guide rail, and the external conveying guide rail is equipped with the conveyed screw.

[0012] The base includes side panels, a bottom plate, a fixed seat, a feed plate, a guide rail, and a nail feeding tube seat. The left and right sides of the bottom plate are connected to the side panels, the front side of the bottom plate is connected to the fixed seat, the nail feeding tube seat passes through the bottom plate and is connected to the fixed seat, the upper end surface of the fixed seat is equipped with a guide rail, and the left and right sides of the fixed seat are equipped with a feed plate.

[0013] Furthermore, the screw cutter is located above the material receiving baffle.

[0014] Furthermore, a circular arc groove is provided in the middle of the fixing seat.

[0015] Furthermore, the protective cover is a sheet metal protective cover, and a sensor window is installed on the front side of the protective cover.

[0016] Furthermore, the screw cutter head has a sharp edge with beveled edges on both sides.

[0017] Furthermore, the material receiving baffle and the screw cutter maintain unchanged relative positions under the action of the cutting cylinder.

[0018] The present invention has the following advantages:

[0019] 1. This mechanism can start cutting any kind of screw from the end of the screw and push it to the bottom of the blowing hole with the oblique edge of the screw cutter;

[0020] 2. This structure starts cutting nails by gradually advancing the tip of the screw cutter, so the screws will not be pressed or stuck;

DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the accompanying drawings and through specific embodiments. It should be pointed out that for ordinary technicians in this process field, without departing from the principle of the present invention, various equivalent forms of modifications to the present invention are within the scope defined by the claims attached to this application. Example

[0030] As shown in Figures 1-5, a screw cutting and output integrated mechanism includes a protective cover 1, a blowing block 2, a base 3, and a cutting mechanism 4, characterized in that the top of the base 3 is connected to the blowing block 2, the blowing block 2 includes a blowing seat and a throttle valve, the blowing seat is connected to the throttle valve, the protective cover 1 is installed on the outside of the base 3, and the base 3 is connected to the cutting mechanism 4.

[0031] The cutting mechanism includes a screw cutter 11, a guide rail piece 12, a conveyed screw 13, a cutting cylinder 14, an external conveying guide rail 15, a fixed seat 16, and a material receiving baffle 17. The left and right sides of the cutting cylinder 14 are respectively connected to the material receiving baffle 17 and the screw cutter 11 through connecting blocks. A fixed seat 16 is installed under the screw cutter 11. The top outer surface of the fixed seat 16 is equipped with a guide rail piece 12. The guide rail piece 12 is connected to the external conveying guide rail 15. The external conveying guide rail 15 is equipped with the conveyed screw 13.

[0032] The base includes side panels 21, a bottom plate 22, a fixed seat 23, a feed plate 24, a guide rail piece 25, and a nail feeding tube seat 26. The left and right sides of the bottom plate 22 are connected to the side panels 21, the front of the bottom plate 22 is connected to the fixed seat 23, the nail feeding tube seat 26 passes through the bottom plate and is connected to the fixed seat 23, the upper end surface of the fixed seat 23 is equipped with a guide rail piece 25, the left and right sides of the fixed seat 23 are equipped with a feed plate 24, the middle part of the feed plate 24 is provided with a long groove to ensure that the screw rod of the screw can enter the integrated mechanism in a suspended state, and the guide rail piece 25 is used to support the two sides of the screw head entering the screw; on the one hand, the fixed seat supports the guide rail piece 25, and on the other hand, the middle position of the fixed seat is provided with an arc groove, which can work together with the arc groove after the screw cutter cuts the nail into place to form a cylindrical hole so that the screw can fall smoothly.

[0033] As a preferred embodiment, the screws are transported in a hanging manner on the external conveying guide rail into the guide rail sheet of the integrated mechanism, and the front end screws are blocked by the material receiving baffle plate, such as Figure 2 As shown; in the state of waiting for cutting, the cutting cylinder is started through the external screw demand signal, and the material receiving baffle and the screw cutter keep the relative position unchanged under the action of the cylinder and move to the state of cutting and blowing nails. In the state of cutting and blowing nails, the screw cutter is designed with double-sided oblique blades. The nail cutting process is similar to the tip of the blade inserting into the middle of two adjacent screws. The two front sides of the blade push the screw to the hole position of the knife through the moving process. The key point is that there is an arc groove design in the middle of the screw cutter. When the nail is cut in place, the groove and the arc groove in the middle of the fixed seat just form a complete circular hole. The hole diameter is slightly larger than the screw head, and the screw falls into the hole; when the nail cutting is in place, the signal is output, and the external controller opens the air valve, and the screw is blown out through the throttle valve on the air blowing block. That is, the position where the nail cutting is completed is the screw blowing position, and the screw moves only a screw head diameter. In addition, because the screw cutter's cutting position is in the middle of adjacent screws, it can smoothly complete the cutting no matter how thin the screw head is. At the same time, the tip of the screw cutter is at the root of the screw. Regardless of whether the screw is skewed or not, due to the close proximity of the screw heads, this position is a stable and effective gap position between the two screws.

[0034] Preferably, the cutting cylinder is started, and the receiving baffle and the screw cutter keep their relative positions unchanged under the action of the cylinder and move to the cutting and nail blowing state to complete the screw cutting action. When the cutting cylinder returns to the cylinder extension state, the next screw entering the integrated mechanism can be blocked by the receiving baffle again, preparing for the next nail cutting. The screw cutter is designed with double-sided bevel blades. The nail cutting process is similar to the tip of the blade being inserted between two adjacent screws. The moving process pushes the screw to the nail hole position through the two front sides of the blade. There is an arc groove design in the middle of the screw cutter. When the nail is cut into place, the groove and the arc groove in the middle of the fixing seat just form a complete round hole. The hole diameter is slightly larger than the screw head, and the screw falls into the hole.

[0035] When the screw cutting is completed, the screw falls into the hole of the nail blowing tube at the cutting completion position, the external control valve opens, and air is blown into the nail feeding tube through the throttle valve to send the screw to the target position; a long groove is opened on the lower side of the blowing seat 01, and its width and height are slightly larger than the screw head, which is convenient for the screw to enter smoothly.

[0036] Action flow of a screw cutting and output integrated mechanism

[0037] The screw enters the guide plate through the external guide rail, and the front end screw is blocked by the material receiving baffle. The screw cutter completes the nail cutting action under the movement of the cylinder. When the action is completed, a complete cylindrical hole is formed, and the screw naturally falls into the hole. The air blow valve opens, and air is blown into the hole through the throttle valve to blow the screw to the target position. The cutting cylinder returns, and the screw cutter and the material receiving baffle return to their original positions together. The next screw enters the nail cutting position and enters the next nail cutting cycle.

[0038] The present invention has the following advantages:

[0039] 1. This weight-removing part is pressed by the pressure head to prevent the workpiece from deflecting during the milling process, which will make the milling amount inaccurate;

[0040] 2. The design of the dust suction port can effectively prevent the falling of waste chips, and play a certain role in cleaning the machine;

[0041] 3. Adjust the height of the power head by adjusting the hand wheel so that the milling height of the power head is constant.

[0042] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
