Description

Technical Field

[0001] This utility model relates to the field of screw processing technology, specifically to a screw processing edge trimming machine with an improved structure. Background Technology

[0002] A screw is a fastener that uses the rotation of a beveled surface and friction to tighten itself into a corresponding object. Screws are used in household appliances and production equipment in daily life. After being manufactured, screws require an edge trimming machine to cut the head of the upset bolt blank into a hexagonal shape. This process is simple to operate.

[0003] Traditional screw trimming machines require manual removal of the screws after trimming them. Since the screws are placed in a slot, removal is inconvenient as it requires manual retraction. Therefore, we propose an improved screw trimming machine with an enhanced structure to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a screw cutting machine with an improved structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screw processing edge trimming machine with an improved structure, comprising a processing table, a table surface fixed to the top of the processing table, a support frame installed at the top of the table surface, an assembly seat installed at the rear end of the top of the support frame, a first telescopic cylinder installed inside the assembly seat, a punching edge trimming head installed at the bottom of the first telescopic cylinder, a second gear movably arranged at the bottom of the processing table, a servo motor installed at the bottom of the second gear, a first gear meshing with the left side of the second gear, a rotating shaft installed at the top of the first gear, an operating table installed at the top of the rotating shaft, a placement groove provided inside the operating table, guide grooves provided on both sides of the operating table, a pusher plate movably arranged inside each placement groove, guide blocks fixed on both sides of the pusher plate, a top block provided at the bottom of the placement groove, a second telescopic cylinder installed at the bottom of the top block, a connecting seat installed at the bottom of the second telescopic cylinder, and the bottom of the connecting seat fixed to one side of the top of the table surface.

[0006] Preferably, there are several placement slots, which are evenly distributed inside the operating table.

[0007] Preferably, the guide blocks are provided in two sets, and the two sets of guide blocks are symmetrically distributed about the central axis of the placement groove.

[0008] Preferably, the cross-section of the guide block is smaller than the cross-section of the guide groove, and the guide block and the guide groove form a sliding structure.

[0009] Preferably, a mounting base is fixed at the middle position of the top of the operating table, a third telescopic cylinder is installed inside the mounting base, and cleaning scrapers are installed on both sides of the third telescopic cylinder.

[0010] Preferably, the cleaning scraper is provided in two sets, and the two sets of cleaning scrapers are symmetrically distributed about the central axis of the operating table.

[0011] Preferably, each of the top ends of the two sides of the placement slot is provided with an installation slot, and the installation slot is located inside the operating table. Each installation slot is equipped with a miniature telescopic cylinder. Each miniature telescopic cylinder has a clamping block fixed on one side, and each clamping block has a rubber block fixed on one side.

[0012] Preferably, there are several clamping blocks, and the clamping blocks are symmetrically distributed in pairs about the central axis of the placement groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the screw processing edge trimming machine with improved structure not only makes it easy to remove the screws after trimming and achieves better positioning of the screws for more accurate processing, but also makes it easier to clean the operating table;

[0014] With components such as a second telescopic cylinder, a pusher plate, and a top block, after the edge trimming machine finishes trimming the screw, the second telescopic cylinder in the above components can push the top block to move upward, so that the top block pushes the pusher plate to move upward and push out the screw placed in the placement groove, so that the screw moves out part of the placement groove, making it convenient for people to take the screw out of the placement groove for unloading.

[0015] By incorporating components such as a cleaning scraper, a third telescopic cylinder, and a mounting base, the internal slot of the operating table is used to place screws. As the operating table surface accumulates debris over time, the addition of these components allows for automatic cleaning of the debris on the operating table, making the debris cleaning of the edge trimming machine more convenient and improving its performance.

[0016] After the screws are placed into the placement slot, there will be screws of different sizes. When encountering screws of different sizes, the machine is equipped with components such as a miniature telescopic cylinder, a clamping block, and a rubber block. The miniature telescopic cylinder can push the clamping block to extend and retract, which makes it easier to limit the screws of different sizes and makes the edge cutting machine more adaptable.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides an embodiment: a screw trimming machine with an improved structure, including a processing table 8, a table surface 9 fixed to the top of the processing table 8, and a support frame 1 installed on the top of the table surface 9. An assembly base 3 is installed at the rear end of the top of the support frame 1, and a first telescopic cylinder 2 is installed inside the assembly base 3. A punching trimming head 4 is installed at the bottom end of the first telescopic cylinder 2. A second gear 11 is movably arranged at the bottom end of the processing table 8, and a servo motor 12 is installed at the bottom end of the second gear 11. A first gear 10 is meshed on the left side of the second gear 11. A rotating shaft 7 is installed at the top of the first gear 10, and an operating table 6 is installed at the top of the rotating shaft 7. A placement groove 25 is provided inside the operating table 6, and guide grooves 16 are provided on both sides inside the operating table 6. The placement grooves 25 are movably arranged inside. There is a pusher plate 17, and guide blocks 15 are fixed on both sides of the pusher plate 17. A top block 20 is provided at the bottom of the placement groove 25. A second telescopic cylinder 14 is installed at the bottom of the top block 20. A connecting seat 13 is installed at the bottom of the second telescopic cylinder 14. The bottom of the connecting seat 13 is fixed to one side of the top of the table 9. There are several placement grooves 25. The several placement grooves 25 are evenly distributed inside the operating table 6. Multiple screws can be placed at one time for processing, which has high processing efficiency. There are two sets of guide blocks 15. The two sets of guide blocks 15 are symmetrically distributed about the central axis of the placement groove 25. The cross-section of the guide block 15 is smaller than the cross-section of the guide groove 16. The guide block 15 and the guide groove 16 form a sliding structure. The design of the guide structure allows the pusher plate 17 to move up and down stably to push the screws for feeding.

[0024] Specifically, such as Figure 2 As shown, after the stamping and trimming head 4 trims the screw placed in the lower placement groove 25, the second telescopic cylinder 14 can be activated to push the top block 20 upward. The upward movement of the top block 20 pushes the pusher plate 17 to move upward from the bottom of the placement groove 25, allowing the pusher plate 17 to push the screw inside the placement groove 25 upward to expose the upper part of the screw, thus making it convenient for the staff to quickly remove the screw.

[0025] A mounting base 19 is fixed at the middle position of the top of the operating table 6. A third telescopic cylinder 18 is installed inside the mounting base 19, and cleaning scrapers 5 are installed on both sides of the third telescopic cylinder 18. There are two sets of cleaning scrapers 5, and the two sets of cleaning scrapers 5 are symmetrically distributed about the central axis of the operating table 6, which makes it more convenient to clean the debris above the operating table 6.

[0026] Specifically, such as Figure 1 and Figure 3 When cleaning the area above the worktable 6, the third telescopic cylinder 18 inside the mounting base 19 is activated. The third telescopic cylinder 18 pushes the cleaning scraper 5 on one side to move to one side, pushing the debris above the worktable 6 down from both sides for cleaning.

[0027] The top of both sides of the placement groove 25 is provided with an installation groove 22, and the installation groove 22 is located inside the operating table 6. A miniature telescopic cylinder 21 is installed inside the installation groove 22. A clamping block 23 is fixed on one side of the miniature telescopic cylinder 21, and a rubber block 24 is fixed on one side of the clamping block 23. There are several clamping blocks 23, and the several clamping blocks 23 are symmetrically distributed in pairs about the central axis of the placement groove 25. The symmetrically distributed clamping blocks 23 provide more stable limit clamping for the screw.

[0028] Specifically, such as Figure 3 and Figure 4 As shown, after the screw is placed inside the placement slot 25, the miniature telescopic cylinders 21 on both sides are activated to push the clamping blocks 23 to move towards both sides of the screw, fitting against both sides of the screw to limit and clamp the screw, so that the screw is stably placed inside the placement slot 25.

[0029] Working principle: In use, screws to be trimmed are placed into the placement groove 25 one by one. After all screws are placed in the placement groove 25, the micro telescopic cylinders 21 on both sides are activated to push the clamping blocks 23 to move towards the sides of the screws to clamp them, so that the screws are stably placed inside the placement groove 25. Then, the first telescopic cylinder 2 is activated to push the stamping trimming head 4 downward to trim the screws. After trimming is completed, the second telescopic cylinder 14 is activated to push the top block 20 upward. The upward movement of the top block 20 pushes the pusher plate 17 from the bottom of the placement groove 25 towards the top block 20. The screw moves upward, causing the upper part of the screw to be exposed under the push of the pusher plate 17. The operator then removes the screw. Next, the second telescopic cylinder 14 is activated again to pull the top block 20 back to its original position, which causes the pusher plate 17 to return to its original position and place a new screw to wait for subsequent processing. Then, the servo motor 12 is activated to drive the second gear 11 to rotate. The rotation of the second gear 11 drives the meshing first gear 10 to rotate. The rotation of the first gear 10 drives the rotating shaft 7 to rotate, causing the operating table 6 above the rotating shaft 7 to rotate, allowing the next set of screws to move to the bottom of the stamping and cutting head 4 for processing. This process is repeated to complete the processing of multiple screws.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
