[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0027] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the structure of the first embodiment of the anti-interference screw guiding mechanism provided by the present invention; Figure 2 for Figure 1 A top view of the main body of the fixture shown; Figure 3 An exploded view of the anti-interference screw guide mechanism provided by the present invention. The anti-interference screw guide mechanism includes:
[0028] 1. Pressure block, 2. Electric screwdriver bit, and 3. Slot plate for placing products;
[0029] The fixture body 4 is disposed above the slot plate 3, and a first guide rod 5 is provided between the two sides inside the fixture body 4. The outer surfaces of the two first guide rods 5 are slidably connected with clamping blocks 6 for locking screws.
[0030] The first elastic element 7 is sleeved on the outer surface of the first guide rod 5;
[0031] In this embodiment, both the first elastic element 7 and the second elastic element 11 are springs. It is understood that in other embodiments, the first elastic element 7 and the second elastic element 11 may also be other elastic objects, such as elastic rubber and disc-shaped springs.
[0032] The four corners of the fixture body 4 are slidably connected with second guide rods 8, the bottom end of the second guide rods 8 penetrating the groove plate 3 and extending into the interior of the groove plate 3;
[0033] The design of raising the second guide rod 8 and the second elastic element 11 to a certain height is to address the issue that when a product enters the slot, because the screws are not tightened, there may be uncontrollable height differences between the two products that need to be fastened. If the height difference is too great, the product will not be able to enter the slot and will not reach the intended screw position. The second elastic element 11 is raised high enough to accommodate the height difference of the products, thus preventing the product from not being able to enter.
[0034] Both sides of the groove plate 3 are provided with first locking screw holes 9, and the first locking screw 10 is connected to the internal thread of the first locking screw hole 9. One side of the first locking screw 10 contacts the bottom end of the second guide rod 8.
[0035] The outer surface of the second guide rod 8 is fitted with a second elastic element 11.
[0036] The two ends of the first guide rod 5 pass through both sides of the jig body 4 and extend into the interior of the jig body 4. The jig body 4 is provided with a second locking screw hole 12. The interior of the second locking screw hole 12 is threaded with a second locking screw 13. One end of the second locking screw 13 contacts one side of the first guide rod 5.
[0037] Limiting blocks 14 are fixedly connected to both sides inside the main body 4 of the fixture. One side of the clamping block 6 contacts the limiting block 14, and both sides of the clamping block 6 are slidably connected to both sides inside the main body 4 of the fixture.
[0038] The main body of the fixture consists of 4 pieces, with the middle hollowed out to accommodate 6 clamping blocks;
[0039] Limiting blocks 14 are placed on both sides of the center line. After the clamping block 6 is pushed to this block by the first elastic element 7, it reaches the center position.
[0040] The main body 4 of the fixture has second locking screw holes 12 on both sides, and the first guide rod 5 is fixed by the second locking screw 13.
[0041] The clamping block 6 has a 45° inclined groove 15 inside, which allows the clamping block 6 to move laterally after being pressed down by the screw.
[0042] The clamping block 6 is made in the shape of a screw and then divided into two halves. A pin hole is opened inside to place the first guide rod 5. This is an important component to ensure that the screw is not interfered with.
[0043] The inner walls of the clamping blocks 6 on both sides act as guides, and the screws are placed in a vertical position.
[0044] The clamping block 6 has a positioning groove 16 on one side edge for clamping and fixing screws.
[0045] The first locking screw hole 9 is adapted to the first locking screw 10.
[0046] The second locking screw hole 12 is adapted to the second locking screw 13.
[0047] The working principle of the anti-interference screw guiding mechanism provided by this invention is as follows:
[0048] Step 1: The product enters through the slot (not shown) on the slot plate 1 and then reaches the bottom of the screw (not shown);
[0049] Step 2: By applying downward pressure, the lower pressure block presses against the upper surface of the jig body 4, and then the second elastic element 11 is compressed and deformed until the jig body 4 reaches the product surface, at which point the screw reaches the screw hole position.
[0050] Step 3: Rotate the electric screwdriver bit 2, and move the electric screwdriver bit 2 downwards;
[0051] Step 4: After the electric screwdriver bit 2 comes into contact with the screw, the screw clamping block 6 moves horizontally along the first guide rod 5 under the rotation and pressing action of the electric screwdriver bit 2 until the screw is locked.
[0052] Step 5: After the screws are tightened, the electric screwdriver bit 2 and the lower pressure block 1 return to their original positions and rise. The main body of the fixture 4 rises to its initial height under the action of the second elastic element 11. The clamping block 6 returns to its central position under the action of the first elastic element 7, waiting for the next product to arrive before starting the next cycle.
[0053] Compared with related technologies, the anti-interference screw guiding mechanism provided by the present invention has the following beneficial effects:
[0054] The lateral clamping of the screw profile prevents external forces from interfering with the screw hole, while also ensuring that the screw is locked in place without deviation or loosening. This improves the accuracy of the screw during installation and avoids interference from external factors.
[0055] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
