Description

Technical Field

[0002] In mathematics and drawing, a compass is a tool used to draw circles or arcs, and is often used in ruler and compass drawing. A compass usually consists of a lead foot that can accommodate a lead core and a pin that can accommodate a positioning pin. The upper ends of the lead foot and the pin are connected together by a fork that can be opened and closed. When in use, the pin is fixed on a plane, and the lead foot can be rotated along the pin to form an arc or circle on the plane. When the compass is being processed, the lead foot is inserted into the lead core and the pin is inserted into the fixing pin.

The needle is sent to the stitch processing platform 5 through the stitch conveying platform 1 to connect the needle, and the lead foot is sent to the lead foot processing platform 6 through the lead foot conveying platform 2 for lead core insertion, and is sent to the fork assembly platform 7 through the fork conveying platform 3 for fork assembly, and then the fork, needle and lead foot are assembled on the assembly platform 8 and the finished product is output from the finished product output platform 4. When in use, the lead foot processing platform 6, the stitch processing platform 5, and the fork assembly platform 7 are connected to the lead foot processing platform 5. And the final assembly table 8, so that they are placed in the same position, and the lead feet, needles, forks and finished products are automatically fed in and out through the lead foot conveying table 2, the needle foot conveying table 1, the fork head conveying table 3 and the finished product output table 4. Only a few people are needed to operate the entire assembly line, with a high degree of automation, no need to manually carry various parts, and high processing efficiency. When processing the needles, the needles conveyed from the needle conveying table 1 are placed in the needle positioning groove 562 on the fixed plate 561, so that they are aligned with the edge of the needle positioning groove 562, and at the same time, the position of the rubber column 565 in the adjustment groove 566 is adjusted to make the needle better align with the needle positioning groove 562, and then the torque motor 22 is started to drive the torque motor 22 to drive the pressure handle 2 The connecting sleeve 231 of 3 rotates, thereby synchronously driving the swing handle 232 and the pressure fixing block 235 provided at the bottom thereof to move, and causing the pressure fixing block 235 to press and contact the pin, so that the adsorption hole 34 is aligned with and fits the pin surface, thereby deforming the rubber block 31, and the compression cavity 32 therein is squeezed and the air inside is pushed out through the exhaust pipe 33. The air pressure causes the sealing piece 36 to be twisted, thereby causing it to lose the effect of sealing the exhaust pipe 33. At the same time, when the airflow is reversed, it will be pushed up again to restore the sealing of the exhaust pipe 33, thereby generating an air pressure difference between the compression cavity 32 and the outside world, and then causing the position of the adsorption hole 34 to generate suction due to the internal and external air pressure difference, cooperating with the enlarged hole 37 to expand the adsorption range. At this time,After absorbing the excessive pressure on the pin, the suction force is used to further improve the fixing effect of the pin, thereby preventing the pin from being squeezed and distorted during the processing, and reducing the scrap rate after processing. Then the pin is aligned with the needle loader 52, and then the needle is loaded into the pin, and the first rotating disk 54 is used to select the drill to rotate the pin after the needle is loaded into the needle nut locker 55, and the needle nut locker is used to lock the pin nut to fix the needle, and then the first rotating disk 54 can be continued to rotate to the position of the pin extractor 53, and the pin after processing is taken out by the pin extractor 53 and placed on the assembly table 8 for assembly preparation. When the lead foot is processed, the lead foot is sent to the lead foot loading station 2 through the lead foot conveying station 2. On the workbench 6, the lead foot is sent into the lead foot inner pusher 62, so that the end of the lead core to be loaded faces the second rotating disk 63, and at the same time, the batch of lead cores are placed in the lead core storage 65, so that the lead core storage 65 can lift the lead core and can be manually loaded into the lead core fixing ring 644 of the lead core fixer 64 provided on the second rotating disk 63, and at the same time, the clamping machine 643 is started to output the clamping force to the buckling force block 44, so that the pressure outer ring 41 drives the contact block 42 to shrink inward along the inward deformation groove 43, and finally makes the inner cavity gap between the contact blocks 42 consistent with the size of the lead core, at this time the lead core can be rotated and loaded into the inner cavity formed by the contact block 42, and it can be aligned with the block 421 of the contact block 42 through the friction groove 422. Friction is generated between them to prevent sliding, and then the second rotating disk 63 can be rotated to drive the lead core fixer 64 to the position of the lead foot inner pusher 62 where the lead foot is placed, and then the lead foot is pushed out by the lead foot inner pusher 62, and the rotating machine 642 drives the clamping machine 643 and the lead core fixing ring 644 and the lead core to rotate and screw the lead core into the lead foot through rotation. During the rotation process, the extrusion force generated by the clamping machine 643 is used to fully fix the lead core. At the same time, when the clamping force is applied to the lead core, the silicone block 421 can cooperate with the deformable airbag 424 to disperse and absorb the clamping force to avoid excessive clamping force from breaking the lead core, and the deformation amplitude of the deformable airbag 424 can be made more controllable through the fiber layer 425 and the elastic fiber thread 426. , to prevent the block 421 from protruding and squeezing the lead core. At the same time, when the lead core is screwed in, if the lead core has a tendency to rotate counterclockwise during the screwing process, the friction groove 422 and the one-way protrusion 423 can fully prevent the lead core from rotating, preventing it from twisting during the installation process and causing loose fixation, effectively reducing the scrap rate generated by the processing. After the lead core is installed, the lead foot can be taken out from the lead foot inner pusher 62, collected and placed on the nearby assembly table 8, and the fork head original output from the fork head transmission table 3 can be assembled on the fork head assembly table 7. Then, the lead foot and pin can be installed into the fork head on the assembly table 8, and the finished product can be output through the finished product output table 4. Only 4-5 people are needed to operate the entire production line, which saves a lot of manpower and greatly improves the processing speed.

[0028] The conveying belts on the stitch conveying platform 1, the lead foot conveying platform 2, the fork conveying platform 3 and the finished product output platform 4 are all provided with a plurality of accommodating grooves 10, which are conducive to placing stitches, lead feet, forks and finished products into the accommodating grooves 10, avoiding separation from the conveying belts during the conveying process, making the conveying more stable;

[0029] The top end of the rotating shaft of the torque motor 22 is engaged with a tightening bolt 24 that squeezes the pressure handle 23, which is conducive to adjusting the connection firmness of the pressure handle 23 through the tightening bolt 24. When lower torque is required, the tightening bolt 24 can be loosened, so that the pressure handle 23 can produce a small range of twisting, which can achieve a better buffering effect.

[0030] Working principle of the present invention: When the present invention is used, the lead foot processing table 6, the stitch processing table 5, the fork assembly table 7 and the final assembly table 8 are combined and placed in the same position, and the lead feet, stitches, forks and finished products are automatically fed in and out through the lead foot conveying table 2, the stitch conveying table 1, the fork transmission table 3 and the finished product output table 4. Only a few people are needed to operate the entire assembly line. The degree of automation is high, and there is no need to manually carry various parts. The processing efficiency is high. When performing stitch processing, the stitches conveyed from the stitch conveying table 1 are placed in the stitch positioning groove 562 on the fixed disk 561, so that they are aligned with the edge of the stitch positioning groove 562. At the same time, the position of the rubber column 565 in the adjustment groove 566 is adjusted to make the stitches better. Align the pin positioning groove 562, then start the torque motor 22, so that the torque motor 22 drives the connecting sleeve 231 of the pressure handle 23 to rotate, and then synchronously drives the swing handle 232 and the pressure fixing block 235 arranged at the bottom thereof to move, and the pressure fixing block 235 is pressed and contacted on the pin, so that the adsorption hole 34 is aligned with and fits the pin surface, thereby causing the rubber block 31 to deform, and then the compression cavity 32 therein is squeezed and the air inside is pushed out through the exhaust pipe 33, and the air pressure causes the sealing piece 36 to be twisted, thereby causing it to lose the effect of sealing the exhaust pipe 33, and at the same time, when the airflow is reversed, it will be pushed up again to restore the closed exhaust pipe 33, thereby causing an air pressure difference between the compression cavity 32 and the outside world, thereby causing the adsorption hole 34 to be compressed. 4 generates suction due to the pressure difference between the inside and outside, and cooperates with the enlarged hole 37 to expand the adsorption range. At this time, after absorbing the excessive pressure on the pin, the suction can be used to further improve the fixing effect of the pin, thereby preventing the pin from being squeezed and skewed during the processing, and reducing the scrap rate after processing. The pin is then aligned with the needle loader 52, and the needle is loaded into the pin, and the first rotating disk 54 is selected to rotate the pin after the needle is loaded into the needle nut locker 55, and the needle nut is locked by the needle nut locker to fix the needle. Then, the first rotating disk 54 can be continued to be rotated to the position of the pin extractor 53, and the pin after processing can be taken out by the pin extractor 53 and placed on the final assembly table 8 for final assembly alignment. When processing the lead foot, the lead foot is sent to the lead foot processing table 6 through the lead foot conveying table 2, and the lead foot is sent to the lead foot inner pusher 62, so that the end where the lead core needs to be loaded faces the second rotating disk 63, and at the same time, the batch of lead cores are placed in the lead core storage 65, so that the lead core storage 65 can lift the lead core and can be manually loaded into the lead core fixing ring 644 of the lead core holder 64 provided on the second rotating disk 63, and at the same time, the clamping machine 643 is started to output the clamping force to the buckled force block 44, so that the pressure outer ring 41 drives the contact block 42 to shrink inward along the inward deformation groove 43, and finally makes the inner cavity gap between the contact blocks 42 consistent with the size of the lead core, at this time the lead core can be rotated and loaded into the inner cavity formed by the contact block 42,And it can generate friction between the block 421 of the contact block 42 through the friction groove 422 to prevent sliding, and then the second rotating disk 63 can be rotated to drive the lead core fixer 64 to the position of the lead foot inner pusher 62 where the lead foot is placed, and then the lead foot is pushed out by the lead foot inner pusher 62, and the rotating machine 642 drives the clamping machine 643 and the lead core fixing ring 644 and the lead core to rotate and screw the lead core into the lead foot through rotation. During the rotation process, the extrusion force generated by the clamping machine 643 is used to fully fix the lead core. At the same time, when the clamping force is applied to the lead core, the silicone block 421 can cooperate with the deformable airbag 424 to disperse and absorb the clamping force to avoid the lead core being broken by excessive clamping force, and the deformable airbag is used to make the fiber layer 425 cooperate with the elastic fiber filament 426 to make the deformable airbag The deformation amplitude of the capsule 424 is more controllable, preventing the block 421 from protruding and squeezing the lead core. At the same time, when the lead core is screwed in, if the lead core has a tendency to rotate counterclockwise during the screwing process, the friction groove 422 and the one-way protrusion 423 can fully prevent the lead core from rotating, preventing it from twisting during the installation process and causing loose fixation, effectively reducing the scrap rate generated during processing. After the lead core is installed, the lead foot can be taken out from the lead foot inner pusher 62, collected and placed on the nearby assembly table 8, and the fork original output from the fork transfer table 3 can be assembled on the fork assembly table 7. Then, the lead foot and pin can be installed into the fork on the assembly table 8, and the finished product can be output through the finished product output table 4. Only 4-5 people are needed to operate the entire production line, which saves a lot of manpower and greatly improves the processing speed.
