Description

Technical Field

[0001] The present invention relates to the technical field of milling processing, and particularly relates to an intelligent and rapid grooving device and method for screw production. Background Art

[0002] A screw milling and grooving device is an automated mechanical device used for machining a straight slot or a cross slot on the head of a screw. It usually includes parts such as a feeding mechanism, a clamping device, a grooving mechanism, and a discharging mechanism. Such devices orderly arrange and feed the screws into the fixture for fixation through a vibrating disk or a conveyor belt, and then a rotating grooving cutter mills the head of the screw. Some devices are also equipped with a cooling system to prevent the tool from overheating. For example, the screw cross-slotting machine described in Patent CN219853136U uses a circular working station disk and two groups of symmetric grooving mechanisms, and can automatically complete processes such as feeding, cross-slotting, drilling, and discharging. In addition, some devices reduce burrs by using double cutters to groove from different directions twice, or use a moving slide rail mechanism to accurately control the grooving depth and width to adapt to different specifications of screws. The overall design focuses on automation and efficiency, replaces traditional manual operations, and improves production accuracy and speed;

[0003] The problem with the existing technology is that when processing a batch of screws, it is necessary to rely on the precise cooperation of a circular working station disk and a grooving cutter blade. During milling, the circular working station disk needs to be stationary for grooving in different directions. In actual processing, the efficiency of such cooperation in a continuous processing scenario needs to be improved. Summary of the Invention

[0004] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this part, the abstract, and the title. However, such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] The present invention provides an intelligent and rapid grooving device and method for screw production, which can solve the problem of low processing efficiency. The specific solutions are as follows:

[0006] On the one hand, the present invention provides an intelligent and rapid grooving device for screw production, including a conveyor belt. Above the conveyor belt, there is a milling device for grooving the heads of screw raw materials. There are several clamps on the conveyor belt. Each clamp has two clamping blocks, and the outer walls of the two clamping blocks have reversing arms. The clamps are used to clamp the screw raw materials. The two ends of the conveyor belt are respectively provided with a first reversing frame and a second reversing frame. The clamps on the conveyor belt circulate in the first reversing frame and the second reversing frame in turn. A first reversing groove and a second reversing groove are respectively formed in the first reversing frame and the second reversing frame. After the screw raw materials are processed by the milling device, they first enter the first reversing frame;

[0007] When the clamp is driven by the conveyor belt to the lower part of the conveyor belt, under the twisting action of the first reversing groove, the two clamping blocks are opened along with the reversing arms to release the screw raw materials;

[0008] When the clamp leaves the first reversing groove and the second reversing groove, the two clamping blocks are in a clamping state under the action of the torsion spring;

[0009] When the clamp is driven by the conveyor belt into the second reversing frame and moves above the conveyor belt, under the twisting action of the second reversing groove, the two clamping blocks are opened again to enable the screw raw material blanks to enter the clamp.

[0010] Preferably, the clamp includes a fixed seat fixed on the conveyor belt. Above the fixed seat, there is a rotating seat configured to rotate only 90 degrees. The two clamping blocks are hinged and installed on the top of the rotating seat through a torsion spring.

[0011] Preferably, a circular step is provided in the middle of the fixed seat, a limiting block is provided on the outer wall of the rotating seat, two blocking blocks are provided on the circular path of the circular step, the two blocking blocks are symmetrically arranged on the circular path of the circular step, and the circular step is stuck between the limiting block and the bottom flange of the rotating seat. The limiting block and the two blocking blocks are made of magnets. The two ends of the limiting block form an S pole and an N pole, and the end of the blocking block close to the limiting block is of the opposite pole.

[0012] Preferably, a feeding rack is provided at one end of the conveyor belt. The heads of several screw raw materials are placed above the feeding rack, and the rod parts of the screw raw materials are suspended below the feeding rack. The feeding rack is inclined. Several screw raw materials are arranged closely in sequence on the feeding rack. A pushing plate is provided on one side of the feeding rack. The head of the pushing plate is triangular. One end of the pushing plate is connected with a telescopic member, the other end of the telescopic member is connected with a support plate, and a feeding cylinder is provided at the lower end of the feeding rack.

[0013] Preferably, the inner wall of the lower end of the first reversing groove forms a first parallel groove, and the first parallel groove gradually twists into a first inclined groove inside the first reversing frame. The shapes of the first parallel groove and the first inclined groove match the shape of the reversing arm.

[0014] Preferably, the inner wall of the second commutation frame forms a second commutation groove, the upper inner wall of the second commutation groove forms a second parallel groove, and the second parallel groove gradually twists into a second inclined groove inside the second commutation frame. The shapes of the second parallel groove and the second inclined groove match the shape of the commutation arm.

[0015] Preferably, a blanking port is provided at the bottom of the second commutation frame. The blanking port is located on the path of the second inclined groove, and a collection box is arranged below the blanking port. The collection box is slidably installed at the bottom of the inner wall of the base.

[0016] Preferably, after the screw raw material is processed by the milling device, the fixture first enters from the second parallel groove at the top of the second commutation frame, and then matches with the second inclined groove in the second commutation groove. The commutation arm is gradually twisted into an inclined state, so that the two commutation arms are in an inclined state, and the two clamping blocks are in an open state, so that the processed screw raw material can be released and fall into the collection box from the blanking port.

[0017] Preferably, a first rack is arranged between the first telescopic column and the second telescopic column, and a second rack is arranged between the second telescopic column and the third telescopic column. The second rack and the first rack are arranged in the opposite direction. Among them, the tops of the first rack and the second rack are both fixed to the support arm through a connecting frame. A toothed ring is formed on the outer wall of the rotating seat. When the rotating seat passes through the first rack and the second rack, it can rotate clockwise and counterclockwise respectively.

[0018] An intelligent and rapid grooving method for screw production includes the following steps:

[0019] S1. Drive a plurality of fixtures to move continuously through a circulating conveyor belt. Each fixture is respectively configured with a pair of clamping blocks with commutation arms;

[0020] S2. When the fixture moves to the processing area above the conveyor belt, the milling device performs grooving processing on the head of the screw raw material fixed by the clamping block;

[0021] S3. The processed fixture enters the first commutation frame along with the conveyor belt. During the downward movement of the conveyor belt, the first commutation groove forces the clamping block to expand through the commutation arm, releasing the processed screw raw material;

[0022] S4. After the fixture disengages from the first commutation groove, the clamping block is reset to the clamping state through a torsion spring;

[0023] S5. The empty fixture continues to circulate to the second commutation frame. During the upward movement of the conveyor belt, the second commutation groove drives the clamping block to expand twice through the commutation arm, and loads the blank of the screw raw material to be processed into the fixture;

[0024] After the fixture finishes loading, it disengages from the second reversing groove. The clamping block is reset by the torsion spring to clamp the screw raw material and enters the next processing cycle along with the conveyor belt.

[0025] Compared with the prior art, the present invention can at least achieve one of the following beneficial effects:

[0026] 1. Through the collaborative design of the conveyor belt and the multi-station fixture, the present invention realizes the continuous automated processing of screw raw materials. The fixture is internally provided with a magnetic rotation structure and an elastic clamping structure, which can automatically complete the clamping angle adjustment and clamping force control during operation, ensuring both the continuity of the screw raw material transportation and the accurate control of the rotation angle, effectively improving the symmetry accuracy and clamping stability of the cross-slot processing. Moreover, the overall solution significantly improves the processing efficiency compared with the prior art.

[0027] 2. By setting the first reversing frame and the second reversing frame, the present invention significantly improves the automation degree of the equipment. The first reversing frame guides the automatic opening and closing of two clamping blocks through the first reversing groove, and cooperates with the inclined feeding frame to achieve accurate blanking; the second reversing frame guides the automatic blanking and collection of the finished products through the second reversing groove. The whole system can complete the loading and unloading cycle without manual intervention, reducing the labor intensity and avoiding manual operation errors.

[0028] 3. Through the linkage design of the first milling cutter, the second milling cutter and the third milling cutter, the traditional single processing limitation is broken through. Through the cooperation of the gear transmission system and the telescopic cutter, the one-word slot cutting, cross-slot forming and chamfering processing are successively completed during a single conveying process, maintaining the consistency of the processing reference and significantly shortening the production cycle through process integration, and significantly improving the processing efficiency.

[0029] 4. Through the formation of a magnetic limiting structure and the transmission of the first rack and the second rack, a double guarantee mechanism is provided. The rotating seat realizes accurate angle limiting through the magnetic block, combined with the physical drive of the first rack / second rack and the ring gear transmission, ensuring both the accurate arrival of each rotation angle and the absorption of transmission errors. Under the double guarantee, the multi-process processing of complex angles reaches higher reliability.

[0030] Other features and advantages of the present invention will be described in the subsequent specification, and part of them will become obvious from the specification or be understood by implementing the present invention. The objectives and other advantages of the present invention can be realized and obtained through the structures specifically pointed out in the written specification and the drawings.

Detailed implementation manner

[0048] The following combines the drawings to specifically describe the preferred embodiments of the present invention. Among them, the drawings form a part of the present invention and are used together with the embodiments of the present invention to explain the principle of the present invention.

[0049] Embodiment 1: As Figure 1 . Figure 2 shown, this embodiment provides an intelligent and fast grooving device for screw production, including a base 1. The two ends and the top of the base 1 are open. Driving rollers 2 are respectively arranged at the two ends of the base 1. The two driving rollers 2 are connected by a conveyor belt 3 in a driving manner. When one of the driving rollers 2 rotates, the other driving roller 2 can rotate synchronously under the drive of the conveyor belt 3. As Figure 2 shown, when processing the screw raw material, the screw raw material 4 is placed from the right end of the conveyor belt 3, and then conveyed to the left side of the base 1 through the fixture on the conveyor belt 3, and the top of the screw raw material 4 is grooved by the milling device on the left side of the base 1.

[0050] As Figure 3 . Figure 4 shown, several fixtures are provided. The several fixtures are evenly distributed on the conveyor belt 3. The fixture includes a fixed seat 5. The fixed seat 5 is fixed on the conveyor belt 3. A rotating seat 6 is arranged above the fixed seat 5. The rotating seat 6 is configured to rotate at most 90 degrees. The specific configuration method is: an annular step 7 is arranged in the middle of the fixed seat 5, a limiting block 8 is arranged on the outer wall of the rotating seat 6, and two stop blocks 9 are arranged on the annular path of the annular step 7. The two stop blocks 9 are symmetrically arranged at the center on the annular path of the annular step 7, and the annular step 7 is stuck between the limiting block 8 and the bottom flange of the rotating seat 6. Therefore, the rotating seat 6 and the fixed seat 5 will not be separated;

[0051] In the above solution, when the rotating seat 6 rotates, the limiting block 8 moves between the two stoppers 9, and the moving range is ninety degrees. The limiting block 8 is made of a magnet, with an S pole and an N pole formed at both ends. The two stoppers 9 are also made of magnets, and the ends of the stoppers 9 close to the limiting block 8 are of opposite polarities. When the limiting block 8 rotates to a state close to any one of the stoppers 9, it can attract to that stopper 9.

[0052] As Figure 4 、 Figure 5 As shown in the figure, a through hole is provided in the middle of the rotating seat 6, which penetrates the upper and lower ends of the rotating seat 6. The through hole allows the rod portion of the screw raw material 4 to penetrate. Clamping blocks 10 are provided at both ends of the rotating seat 6. The clamping blocks 10 are hingedly installed at both ends of the top of the rotating seat 6. Hinge seats 11 are connected to both ends of the top of the rotating seat 6. Hinge holes 10a are provided at the bottoms of the clamping blocks 10. The hinge holes 10a are hinged to the hinge seats 11 through torsion springs (not shown in the figure). Grooves 10b are provided in the middle of the clamping blocks 10. Commutating arms 10c are connected to the outside of the clamping blocks 10. Under the elastic force of the torsion spring, the commutating arms 10c on the two clamping blocks 10 are in a horizontal state, that is, the two clamping blocks 10 are in a clamping state.

[0053] As Figure 6 As shown in the figure, as a feeding method for the screw raw material 4, a feeding rack 13 can be provided at one end of the conveyor belt 3. The heads of several screw raw materials 4 are placed above the feeding rack 13, and the rod portions are suspended below the feeding rack 13. The feeding rack 13 is inclined. Several screw raw materials 4 are arranged closely in sequence on the feeding rack 13. A pushing plate 14 is provided on one side of the feeding rack 13. The head of the pushing plate 14 is triangular. One end of the pushing plate 14 is connected to a telescopic member 15. The other end of the telescopic member 15 is connected to a support plate 16. A feeding tube 21 is provided at the lower end of the feeding rack 13. The telescopic member 15 can be an electric telescopic rod or a hydraulic rod.

[0054] As Figure 7 As shown in the figure, a first commutating rack 12 is provided on the right side of the conveyor belt 3. The bottom of the support plate 16 is fixed to the top of the first commutating rack 12. A feeding port 20 is provided at the top end of the first commutating rack 12. The bottom of the feeding tube 21 is concentrically arranged with the feeding port 20. A first commutating groove 17 is provided on the inner wall of the first commutating rack 12. The lower inner wall of the first commutating groove 17 forms a first parallel groove 18, and the upper inner wall of the first commutating groove 17 forms a first inclined groove 19 (the first parallel groove 18 gradually twists into the first inclined groove 19 inside the first commutating rack 12). The shapes of the first parallel groove 18 and the first inclined groove 19 match the shape of the commutating arm 10c;

[0055] In the above solution, when the fixture rotates to the lower part of the conveyor belt 3 and enters from the bottom end of the first reversing groove 17, the reversing arm 10c first enters the first parallel groove 18. As the conveyor belt 3 rotates, the reversing arm 10c gradually matches the shape of the first reversing groove 17 during its movement in the first reversing groove 17, and twists synchronously with the first inclined groove 19, so that the reversing arm 10c is twisted into an inclined state, so that the two clamping blocks 10 are in an open state, so that the screw raw material 4 can fall from the feed port 20 onto the fixture (specifically into the through hole on the rotating seat 6). As the conveyor belt 3 rotates, after the fixture exits from the first inclined groove 19 at the top of the first reversing frame 12, under the action of the torsion spring, the two clamping blocks 10 return to the clamped state, so as to stably clamp the head of the screw raw material 4, facilitating the subsequent grooving work.

[0056] As Figure 8 , Figure 9 , Figure 10 , Figure 11 shown, the milling device above the conveyor belt 3 includes a support arm 22. A motor 23 is installed at the left end of the support arm 22. From right to left below the support arm 22 are a first telescopic column 24, a second telescopic column 25, and a third telescopic column 26. A first milling cutter 27, a second milling cutter 28, and a third milling cutter 29 are sequentially connected below the first telescopic column 24, the second telescopic column 25, and the third telescopic column 26. The bottom output end of the motor 23 is connected to a driving wheel 30. The tops of the third telescopic column 26 and the second telescopic column 25 are respectively connected to a first gear 31 and a second gear 32. The second gear 32 meshes with the first gear 31. The tops of the first telescopic column 24 and the first gear 31 are respectively connected to a first driven wheel 33 and a second driven wheel 34. The first driven wheel 33, the second driven wheel 34, and the driving wheel 30 rotate synchronously through a timing belt 35;

[0057] In the above solution, during the process of the screw raw material 4 moving from right to left, first, a "slotted crosshead" is machined on the head of the screw raw material 4 by the first milling cutter 27. Then the rotating seat 6 rotates 90 degrees, and a groove perpendicular to the "slotted crosshead" is machined on the head of the screw raw material 4 by the second milling cutter 28, so that a "Phillips head" is formed on the head of the screw raw material 4. Then the rotating seat 6 rotates 90 degrees again, and then the conveyor belt 3 pauses briefly. The third milling cutter 29 approaches the head of the screw raw material 4 under the drive of the third telescopic column 26, and mills the middle part of the "Phillips head" in the above text to form a chamfer; it should be noted that the third milling cutter 29 is an optional solution;

[0058] The effect brought by the above solution is that the rotation directions of the first milling cutter 27, the second milling cutter 28, and the third milling cutter 29 can be the same as the ends of the limiting block 8 and the stopper 9 that are close to each other, preventing the first milling cutter 27, the second milling cutter 28, and the third milling cutter 29 from transmitting the rotational torque to the screw raw material 4 and the rotating seat 6. Through this solution, no matter how large the torque of the first milling cutter 27, the second milling cutter 28, and the third milling cutter 29 is, the rotating seat 6 will not rotate and will always rotate relative to the fixed seat 5, thus avoiding angular deviation during the milling process.

[0059] It should be noted that in the above solution, the driving wheel 30, the first driven wheel 33, and the second driven wheel 34 can be pulley wheels or sprocket wheels, and the synchronous belt 35 can be a belt or a chain.

[0060] As Figure 12 , Figure 13 shown, a second reversing frame 36 is provided on the left side of the conveyor belt 3. The inner wall of the second reversing frame 36 is provided with a second reversing groove 37. The upper inner wall of the second reversing groove 37 is provided with a second parallel groove 38, and the lower inner wall of the second reversing groove 37 is provided with a second inclined groove 39 (the second parallel groove 38 gradually twists into the second inclined groove 39 inside the second reversing frame 36). The shapes of the second parallel groove 38 and the second inclined groove 39 match the shape of the reversing arm 10c.

[0061] As Figure 8 shown, a blanking port 40 is provided at the bottom of the second reversing frame 36. The blanking port 40 is located on the path of the second inclined groove 39. A collection box 41 is provided below the blanking port 40, and the collection box 41 is slidably installed at the bottom of the inner wall of the base 1.

[0062] In the above solution, after the screw raw material 4 is processed by the milling device, the fixture first enters from the second parallel groove 38 at the top of the second reversing frame 36, and then matches with the second inclined groove 39 in the second reversing groove 37. The reversing arm 10c is gradually twisted into an inclined state, so that the two reversing arms 10c are in an inclined state, and the two clamping blocks 10 are in an open state, so that the processed screw raw material 4 can be released and fall into the collection box 41 from the blanking port 40, thus completing the processing.

[0063] As Figure 14 shown, as a way to drive the rotation of the rotating seat 6, the following solution can be adopted:

[0064] A first rack 42 is arranged between the first telescopic column 24 and the second telescopic column 25, and a second rack 43 is arranged between the second telescopic column 25 and the third telescopic column 26. The second rack 43 and the first rack 42 are arranged in opposite directions. The tops of the first rack 42 and the second rack 43 are both fixed to the support arm 22 through a connecting frame. A toothed ring 44 is formed on the outer wall of the rotating seat 6. When the rotating seat 6 passes by the first rack 42 and the second rack 43, it can rotate clockwise and counterclockwise respectively;

[0065] It should be noted that in the above solution, according to the description in the above text that "the limiting block 8 is made of a magnet, with an S pole and an N pole formed at both ends, and the two blocking blocks 9 are also made of magnets, and the ends of the blocking blocks 9 close to the limiting block 8 are of opposite poles. When the limiting block 8 rotates to a state close to any one of the blocking blocks 9, it can attract to this blocking block 9", therefore, the number of teeth of the first rack 42 and the second rack 43 does not need to exactly correspond to one-fourth of the number of teeth of the toothed ring 44 (a slightly smaller number is also acceptable, and the specific quantity depends on the magnetic range of the magnet). It only needs to make the rotating seat 6 rotate a certain angle, and the remaining angle can use the magnetism to automatically complete a ninety-degree rotation of the rotating seat 6 together with the limiting block 8;

[0066] It should also be noted that in the above solution, holes corresponding to a number of jigs are provided on the conveyor belt 3 to facilitate corresponding to the rod parts of the screw raw materials 4. Correspondingly, an annular groove is provided in the middle of the driving roller 2 to achieve avoidance of the rod parts of the screw raw materials 4.

[0067] Embodiment 2: The technical solution of this embodiment is different from that of Embodiment 1 in that this embodiment provides an intelligent and rapid grooving method for screw production, including the following steps:

[0068] S1. The screw raw materials 4 are arranged in sequence through the inclined feeding frame 13. The pushing plate 14 pushes the screw raw materials to the blanking cylinder 21 under the drive of the telescopic member 15. The blanking cylinder 21 is aligned with the feeding port 20 of the first reversing frame 12, and the screw raw materials vertically fall from the feeding port 20;

[0069] S2. When the conveyor belt 3 carries the jig and runs to the bottom of the first reversing frame 12, the reversing arm 10c of the jig enters the first reversing groove 17. Through the guidance of the first parallel groove 18 and the first inclined groove 19, the clamping block 10 is forced to open, and the rod part of the screw raw material 4 falls into the through hole of the rotating seat 6. After the jig leaves the first reversing frame 12, the clamping block 10 closes under the action of the torsion spring and clamps the head of the screw raw material 4;

[0070] S3. The conveyor belt 3 conveys the clamped screw raw materials to the lower part of the first milling cutter 27. The motor 23 drives the first milling cutter 27 to rotate through the driving wheel 30 and the synchronous belt 35, and cuts out a "slotted cross recess";

[0071] S4. After the processing in S3 is completed, the fixture passes through the first rack 42. The rack meshes with the toothed ring 44 of the rotating seat 6, driving the rotating seat 6 to rotate clockwise by 90°. The magnetic attraction type stopper 9 and the limiting block 8 attract each other with opposite polarities, ensuring accurate positioning of the rotation angle.

[0072] S5. After the screw raw material rotates by 90°, the second milling cutter 28 processes a groove perpendicular to the "slotted cross recess" to form a "Phillips recess".

[0073] S6. The fixture rotates by 90° again. The third milling cutter 29 presses down through the third telescopic column 26 to mill and chamfer the middle part of the Phillips recess, improving the smoothness of the groove opening.

[0074] S7. The processed screws enter the second reversing frame 36 along with the conveyor belt 3. The reversing arm 10c moves along the second reversing groove 37, and the clamping block 10 is guided to open through the second inclined groove 39. The finished products fall into the collection box 41 from the blanking port 40.

[0075] S8. After the fixture detaches from the second reversing frame 36, the clamping block 10 resets and closes under the action of the torsion spring, and the conveyor belt 3 continues to supply materials in a cycle.
