Description

Technical Field

[0001] The present invention relates to the technical field of screw processing, and specifically, it is a fixing device for screw processing. Background Technique

[0002] A screw is a common fastener, widely used in machinery, electrical appliances and buildings. Generally, the material is metal or plastic, cylindrical in shape, and the surface is engraved with concave and convex grooves called threads.

[0003] A screw generally includes a screw head, a screw rod part and a screw tail part. When traditional screws are processed, the screw head is first stamped out, then the thread part is processed on the screw rod part through a turning process, and finally high and low tooth threads are formed on the outer peripheral wall of the thread part blank diameter through a thread rolling device.

[0004] When stamping and processing the screw end, it is first necessary to clamp and fix the steel wire. When the existing fixing device is in use, it usually directly extrudes and fixes the steel wire. After stamping, the equipment cuts the steel wire, and the stamped screw directly falls at the stamping position. When continuously stamping and processing the steel wire, the position of the screw cannot be automatically adjusted, and it is necessary to manually collect and clean the stamped screw. Even when cutting the steel wire, when the steel wire is not completely cut off, the steel wire cannot be effectively separated from the screw, and the use effect is poor. Summary of the Invention

[0005] The purpose of the present invention is to provide a fixing device for screw processing to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

Between the two groups of vertical plates, two groups of oppositely distributed fixing blocks are arranged horizontally. The fixing blocks are of strip-shaped structures. On the opposite side walls of the two fixing blocks, fixing holes are respectively opened. The transverse section of the fixing hole is of a semi-circular structure. At the bottom wall of the fixing block, an end groove communicating with the bottom end of the fixing hole is opened. At the top inside of the fixing hole, a shearing block is fixedly installed. The two vertical plates are jointly installed with a winding roller located above the fixing blocks. A steel wire is wound on the surface of the winding roller. Between the two vertical plates, a telescopic assembly is arranged and is matched with the fixing blocks. The telescopic assembly is used to control the relative movement of the two fixing blocks horizontally. On the surface of the workbench, a stamping part is arranged below the fixing blocks. The two fixing blocks jointly set a clamping mechanism matched with the fixing holes. The clamping mechanism includes a clamping strip, a positioning assembly and an adjusting assembly. The positioning assembly is located in one of the fixing blocks and is connected with the clamping strip. The positioning assembly is used to control the clamping strip to be at the side wall of the fixing hole. The adjusting assembly is located on the side wall of the other fixing block. The adjusting assembly adjusts the relative positions of the clamping strip and the two fixing blocks by cooperating with the positioning assembly.

[0008] As a further scheme of the present invention: The telescopic assembly includes two groups of oppositely distributed side plates fixedly installed between the two vertical plates. Two groups of oppositely distributed threaded rods are rotatably installed on the two side plates. The thread directions on both sides of the threaded rod are opposite. The two fixing blocks are respectively spirally connected with the threaded rods. Synchronous toothed disks are fixedly installed on the surface of the threaded rods. The two synchronous toothed disks are jointly connected with a synchronous belt. One end of one of the threaded rods extends to the outside of the side plate and is connected with a motor.

[0009] As a further scheme of the present invention: The stamping part includes an electric telescopic rod fixedly installed on the surface of the workbench. The telescopic end of the electric telescopic rod is fixedly installed with a stamping plate.

[0010] As a further scheme of the present invention: The positioning assembly includes a plurality of horizontally arranged storage grooves opened on the side wall of one of the fixing blocks. The storage grooves communicate with the fixing holes. The clamping strip is located in the storage grooves. A plurality of telescopic cavities at the same height as the storage grooves are opened in the fixing block. A connecting rod is fixedly installed on the side wall of the clamping strip. The end of the connecting rod far away from the clamping strip extends into the telescopic cavity and is fixedly installed with a sliding block. The sliding block is slidably connected with the telescopic cavity.

[0011] As a further scheme of the present invention: The adjusting assembly includes a compression spring fixedly installed at one end of the telescopic cavity close to the storage groove. The compression spring surrounds the connecting rod and is connected with the sliding block. The clamping strip is made of a magnetic material. A magnetic strip matched with the clamping strip is fixedly installed on the side wall of the fixing block without the storage groove.

[0012] As a further solution of the present invention: limiting grooves distributed in the horizontal direction are respectively formed on the opposite side walls of the two groups of vertical plates, and limiting blocks are respectively and fixedly installed at both ends of the fixing block, and the limiting blocks are slidably connected with the limiting grooves.

[0013] As a still further solution of the present invention: a heating plate is fixedly installed between the two groups of vertical plates, the heating plate is located between the winding roller and the fixing block, and a guiding hole penetrating through the upper and lower ends is formed in the middle of the heating plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: by arranging the positioning component and the adjusting component to cooperate with each other, the relative positions of the clamping strip and the two groups of fixing blocks can be conveniently adjusted. After the stamping is completed, the stamped screws can be conveniently transferred and then automatically taken out; the problem that the stamped screws directly fall at the stamping position and manual collection and cleaning of the screws are required is solved. When there is a connection at the shearing place of the steel wire, when the two groups of fixing blocks move away from each other after stamping, the clamping strip and the fixing block cooperate with each other to pull the screw to move synchronously, and the screw can be pulled away from the shearing place, so that the screw is separated from the steel wire; the problem that when the steel wire is sheared and not completely cut off, the steel wire cannot be effectively separated from the screw and the use effect is poor is solved.

Specific embodiments

[0023] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0024] The following describes in detail the specific implementation of the present invention in combination with specific embodiments.

[0025] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown in

[0026] Initially, the two groups of fixing blocks 3 are separated from each other, and the positioning component 82 positions and fixes the clamping strip 81. At this time, the clamping strip 81 is located at the side wall of one group of fixing blocks 3. The winding roller 5 rotates to release the steel wire, and the steel wire moves downward between the two groups of fixing blocks 3. The telescopic component 6 controls the relative movement of the two groups of fixing blocks 3, so that the two groups of fixing blocks 3 fit together. The two fixing holes 31 are combined to form a cylindrical structure, and the steel wire is located in the fixing hole 31. The two groups of fixing blocks 3 squeeze and fix the steel wire. The shear block 33 at the inner top of the fixing hole 31 can automatically cut the steel wire. After the steel wire is fixed, the stamping part 7 can automatically stamp the steel wire in the end groove 32 at the bottom wall of the fixing block 3. After the stamping is completed, the telescopic component 6 controls the two groups of fixing blocks 3 to move away from each other in the horizontal direction. The adjusting component 83 and the positioning component 82 cooperate with each other, so that the clamping strip 81 and the group of fixing blocks 3 without the storage groove 821 are integrated. When the group of fixing blocks 3 without the storage groove 821 moves to one side, it drives the clamping strip 81 to move synchronously. The clamping strip 81 and the fixing block 3 cooperate with each other to continue to fix the stamped screw in the fixing hole 31. When the group of fixing blocks 3 without the storage groove 821 moves to one side, it drives the screw to move synchronously. When the fixing block 3 moves a certain distance, the adjusting component 83 releases the positioning of the clamping strip 81, and the positioning component 82 adjusts the position of the clamping strip 81 again. The clamping strip 81 moves back into the storage groove 821 again. At this time, the screw drops from the side wall of the group of fixing blocks 3 without the storage groove 821. At this time, the screw has moved away from the stamping part 7. A corresponding collection box is placed on the surface of the workbench 1, and the screw dropped from the fixing hole 31 can automatically fall into the collection box.

[0027] The two shear blocks 33 cut the steel wire and then continuously stamp to form a plurality of screws. When the shear block 33 does not completely cut the steel wire, there is a connection at the cutting point of the steel wire. When the two groups of fixing blocks 3 move away from each other after stamping, the clamping strip 81 and the fixing block 3 cooperate with each other to pull the screw to move synchronously, and the screw can be pulled away from the cutting point, so that the screw is separated from the steel wire.

[0028] As Figure 1 , Figure 2 , Figure 3 As shown in

[0029] During use, the motor 65 drives a group of threaded rods 62 to rotate. The threaded rods 62 drive the synchronous sprockets 63 to rotate. The two groups of synchronous sprockets 63 cooperate with the synchronous belt 64 to drive the two groups of threaded rods 62 to rotate synchronously. The threaded rods 62 can push the two fixed blocks 3 to move relatively between the two vertical plates 2. When the two fixed blocks 3 move relatively, they can squeeze and fix the steel wire in the fixing holes 31. After the stamping is completed, the two fixed blocks 3 move away from each other, and thus the stamped screws can be automatically taken out.

[0030] As Figure 1 , Figure 2 shown, as a preferred embodiment of the present invention, the stamping part 7 includes an electric telescopic rod 71 fixedly installed on the surface of the workbench 1, and a stamping plate 72 is fixedly installed at the telescopic end of the electric telescopic rod 71.

[0031] After the two fixed blocks 3 squeeze and fix the steel wire through the fixing holes 31, the electric telescopic rod 71 pushes the stamping plate 72 to move upward. At this time, the stamping plate 72 can automatically stamp the cut steel wire at the end groove 32, and form the end head of the screw in the end groove 32.

[0032] As Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 shown, as a preferred embodiment of the present invention, the positioning assembly 82 includes a plurality of horizontally arranged storage grooves 821 opened on the side wall of a fixed block 3. The storage grooves 821 communicate with the fixing holes 31. The clamping strip 81 is located in the storage grooves 821. A plurality of telescopic cavities 822 at the same height as the storage grooves 821 are opened in the fixed block 3. A connecting rod 824 is fixedly installed on the side wall of the clamping strip 81. One end of the connecting rod 824 away from the clamping strip 81 extends into the telescopic cavity 822 and is fixedly installed with a sliding block 823. The sliding block 823 is slidably connected to the telescopic cavity 822.

[0033] Multiple sets of sliding blocks 823 cooperate with the connecting rod 824 to position the clamping strip 81. The clamping strip 81 is located in the storage groove 821. When the two sets of fixing blocks 3 squeeze and fix the steel wire, the clamping strip 81 in the storage groove 821 will not interfere with the entire extrusion process. When the set of fixing blocks 3 without the storage groove 821 moves to one side after stamping, the adjusting component 83 controls the clamping strip 81 to move synchronously with it. The clamping strip 81 continuously squeezes and positions the screw, and the screw moves synchronously with the fixing block 3. At this time, the sliding block 823 moves synchronously in the telescopic cavity 822. After the fixing block 3 moves a certain distance, the adjusting component 83 releases the positioning of the clamping strip 81 at the side wall of the fixing block 3. The adjusting component 83 pushes the sliding block 823 to move reversely in the telescopic cavity 822. The sliding block 823 and the connecting rod 824 cooperate with each other to pull the clamping strip 81 to move reversely into the storage groove 821.

[0034] As Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 shown, as a preferred embodiment of the present invention, the adjusting component 83 includes a compression spring 832 fixedly installed at one end of the telescopic cavity 822 close to the storage groove 821. The compression spring 832 surrounds the outside of the connecting rod 824 and is connected to the sliding block 823. The clamping strip 81 is made of a magnetic material, and a magnetic strip 831 cooperating with the clamping strip 81 is fixedly installed on the side wall of the set of fixing blocks 3 without the storage groove 821.

[0035] When the two sets of fixing blocks 3 move relatively and fit together, the magnetic strip 831 on the side wall of the set of fixing blocks 3 without the storage groove 821 is connected to the clamping strip 81 as a whole through magnetic attraction. After stamping is completed, the set of fixing blocks 3 without the storage groove 821 moves to one side, and the magnetic strip 831 drives the clamping strip 81 to move synchronously with the fixing block 3. The clamping strip 81 and the fixing block 3 cooperate with each other to continuously position the screw in the fixing hole 31. At this time, the sliding block 823 moves synchronously in the telescopic cavity 822 and squeezes the compression spring 832. After the two sets of fixing blocks 3 move away from each other by a certain distance, when the thrust of the compression spring 832 on the sliding block 823 is greater than the magnetic attraction of the magnetic strip 831 on the clamping strip 81, the clamping strip 81 and the magnetic strip 831 are separated from each other. At this time, the screw falls out of the fixing hole 31. The compression spring 832 pushes the sliding block 823 to move reversely in the telescopic cavity 822. The sliding block 823 and the connecting rod 824 cooperate with each other to pull the clamping strip 81 to move reversely into the storage groove 821.

[0036] As Figure 1 , Figure 2 , Figure 5As shown, as a preferred embodiment of the present invention, limiting grooves 9 distributed in the horizontal direction are respectively formed on the opposite side walls of the two groups of vertical plates 2. The two ends of the fixing block 3 are respectively fixedly installed with limiting blocks 10, and the limiting blocks 10 are slidably connected with the limiting grooves 9.

[0037] When the two groups of fixing blocks 3 move relatively, the limiting blocks 10 move synchronously in the limiting grooves 9. The cooperation between the limiting blocks 10 and the limiting grooves 9 can effectively improve the stability of the fixing blocks 3.

[0038] As Figure 1 、 Figure 2 、 Figure 3 As shown, as a preferred embodiment of the present invention, a heating plate 4 is fixedly installed between the two groups of vertical plates 2. The heating plate 4 is located between the winding roller 5 and the fixing block 3, and a straightening hole 41 penetrating through the upper and lower ends is formed in the middle of the heating plate 4.

[0039] When the steel wire is released, the steel wire passes through the straightening hole 41, and the heating plate 4 heats the steel wire, which is convenient for straightening and stamping the steel wire.

[0040] The working principle of the present invention is as follows: Initially, the two groups of fixing blocks 3 are separated from each other. The multiple groups of sliding blocks 823 and the connecting rods 824 cooperate with each other to position the clamping strip 81. The clamping strip 81 is located in the receiving groove 821. The winding roller 5 rotates to release the steel wire. The steel wire moves downward between the two groups of fixing blocks 3. The motor 65 drives a screw rod 62 to rotate. The screw rod 62 drives the synchronous gear disk 63 to rotate. The two synchronous gear disks 63 and the synchronous belt 64 cooperate with each other to drive the two screw rods 62 to rotate synchronously. The screw rods 62 can push the two groups of fixing blocks 3 to move relatively between the two groups of vertical plates 2, so that the two groups of fixing blocks 3 are mutually attached. The two fixing holes 31 are combined to form a cylindrical structure. The steel wire is located in the fixing hole 31. The two groups of fixing blocks 3 squeeze and fix the steel wire. The shearing block 33 at the inner top of the fixing hole 31 can automatically cut the steel wire. After the steel wire is fixed, the electric telescopic rod 71 pushes the stamping plate 72 to move upward. At this time, the stamping plate 72 can automatically stamp the cut steel wire at the end head groove 32 to form the end head of the screw in the end head groove 32.

[0041] After the stamping is completed, control the two groups of fixing blocks 3 to move away from each other in the horizontal direction. The group of fixing blocks 3 without the storage groove 821 moves towards one side. The magnetic strip 831 drives the clamping strip 81 to move synchronously with the fixing block 3. The clamping strip 81 and the fixing block 3 cooperate with each other to continue fixing the stamped screw in the fixing hole 31. At this time, the sliding block 823 moves synchronously in the telescopic cavity 822 and squeezes the compression spring 832. When the group of fixing blocks 3 without the storage groove 821 moves towards one side, it drives the screw to move synchronously. When the fixing block 3 moves a certain distance, after the thrust of the compression spring 832 on the sliding block 823 is greater than the magnetic attraction of the magnetic strip 831 on the clamping strip 81, the clamping strip 81 and the magnetic strip 831 are separated from each other. At this time, the screw falls out of the fixing hole 31. At this time, the screw has moved away from the stamping part 7. Place a corresponding collection box on the surface of the workbench 1, and the screw falling from the fixing hole 31 can automatically fall into the collection box. The compression spring 832 pushes the sliding block 823 to move reversely in the telescopic cavity 822. The sliding block 823 and the connecting rod 824 cooperate with each other to pull the clamping strip 81 to move reversely into the storage groove 821.

[0042] The two groups of shearing blocks 33 cut the steel wire to continuously stamp and form a plurality of screws. When the shearing blocks 33 do not completely cut the steel wire, there is a connection at the shearing point of the steel wire. When the two groups of fixing blocks 3 move away from each other after stamping, the clamping strip 81 and the fixing block 3 cooperate with each other to pull the screw to move synchronously, and the screw can be pulled away from the shearing point, so that the screw is separated from the steel wire.

[0043] The above has described the preferred embodiments of the present invention in detail, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the spirit of the present invention.
