Description

Technical Field

[0001] This utility model relates to the field of riveting technology, specifically a screw riveting positioning device. Background Technology

[0002] Riveting equipment is a type of mechanical equipment developed based on the principle of cold rolling, which uses rivets to rivet items together. This equipment mainly relies on rotation and pressure to complete the assembly and is widely used in various occasions that require riveting.

[0003] Chinese Patent Publication No. CN209614008U discloses a screw riveting positioning device, including a fixed base adapted to house a housing, with a first mounting groove at the edge of the fixed base for accommodating a screw; a screw positioning member rotatably mounted on the fixed base, having a crank arm portion disposed away from the edge of the fixed base, and a positioning portion formed at the end of the crank arm portion that matches a screw through hole; and a biasing member for applying a biasing force to the crank arm portion to rotate in the screw direction. The screw riveting positioning device provided by this utility model, with the screw positioning member rotatably mounted on the fixed base, having a crank arm portion disposed away from the edge of the fixed base, and a positioning portion formed at the end of the crank arm portion that matches a screw through hole, allows for a relatively thick edge to be set, making it less prone to breakage and thus extending the service life of the screw riveting positioning device.

[0004] However, in actual use, the above-mentioned device requires multiple dovetail grooves to be opened on the fixed base, and components such as crank arms need to be installed on the fixed base, which makes it difficult to manufacture. Summary of the Invention

[0005] The technical problem solved by this utility model is to overcome the defects of the prior art and provide a screw riveting positioning device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A screw riveting positioning device includes a fixed base. A groove is formed on the right side of the fixed base, and a screw mounting block is movably inserted into the inner cavity of the groove. A fixing strip is fixedly connected to the left side of the screw mounting block, and a limiting strip is fixedly connected to the front side of the screw mounting block. A dovetail groove is formed on the left side of the inner cavity of the groove, and a limiting groove is formed on the front side of the inner cavity of the groove. A through hole is formed on the screw mounting block, and a ring is formed on the top of the screw mounting block. Limiting rods are fixedly connected to the front and left sides of the ring. Two limiting holes are formed on the top of the fixed base, and a screw is movably inserted into the inner cavity of the ring.

[0008] Preferably, the cross-section of the fixing strip is an isosceles trapezoid, and the fixing strip is movably inserted into the inner cavity of the dovetail groove.

[0009] Preferably, the limiting strip is movably inserted into the inner cavity of the limiting groove, and the limiting strip and the limiting groove are matched with each other.

[0010] Preferably, the limiting rod has an L-shaped cross-section and is movably inserted into the inner cavity of an adjacent limiting hole.

[0011] Preferably, the bottom end of the screw extends through the hole, and the screw fits against the top of the ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model discloses a screw riveting positioning device. The edge of the fixing seat is detachably equipped with a screw mounting block. Since the edge of the fixing seat is prone to wear and breakage after long-term use, the screw mounting block reduces maintenance and replacement costs. When installing the screw mounting block, simply move the screw mounting block into the groove cavity, then move the ring to insert the limiting rod into the corresponding limiting hole cavity. Finally, the screw passes through the ring and the hole. After the screw completes the riveting, the screw presses the ring tightly onto the fixing seat, and the ring fixes the screw mounting block. This device is simple to operate and easy to manufacture. Attached Figure Description

The limiting strip 6 is movably inserted into the inner cavity of the limiting groove 8. The limiting strip 6 and the limiting groove 8 match each other. The top of the screw mounting block 3 is provided with a ring 9. The front and left sides of the ring 9 are fixedly connected to limiting rods 10. The top of the fixing seat 1 has two limiting holes 11. The inner cavity of the ring 9 is movably inserted with a screw 12. The cross-section of the limiting rod 10 is L-shaped. The limiting rod 10 is movably inserted into the inner cavity of the adjacent limiting hole 11. The bottom end of the screw 12 movably passes through the through hole 4. The screw 12 and the top of the ring 9 fit together.

[0023] Working principle: This utility model discloses a screw riveting positioning device. In use, first install the screw mounting block 3, move the screw mounting block 3 to the rear side of the fixing seat 1, align the fixing strip 5 with the dovetail groove 7, and then move the screw mounting block 3 forward. The screw mounting block 3 moves to the inner cavity of the groove 2. The screw mounting block 3 drives the fixing strip 5 to move in the inner cavity of the dovetail groove 7. The screw mounting block 3 drives the limiting strip 6 to move to the inner cavity of the limiting groove 8. Then move the ring 9. The ring 9 moves to the top of the screw mounting block 3. The ring 9 drives the limiting rod 10 to be inserted into the inner cavity of the corresponding limiting hole 11. The ring 9 moves to be in contact with the top of the screw mounting block 3. Then move the screw 12. The screw 12 passes through the ring 9 and the through hole 4. After the screw 12 completes the riveting, the screw 12 presses the ring 9 onto the fixing seat 1, and the ring 9 fixes the screw mounting block 3.

[0024] The edge of the fixed base 1 is detachably equipped with a screw mounting block 3. Since the edge of the fixed base 1 is prone to wear and breakage after long-term use, the screw mounting block 3 reduces maintenance and replacement costs. When installing the screw mounting block 3, simply move the screw mounting block 3 into the inner cavity of the groove 2, then move the ring 9 to insert the limiting rod 10 into the inner cavity of the corresponding limiting hole 11, and finally the screw 12 passes through the ring 9 and the through hole 4. After the screw 12 completes the riveting, the screw 12 presses the ring 9 onto the fixed base 1, and the ring 9 fixes the screw mounting block 3. The screw mounting block 3 is easy to install and has low manufacturing difficulty.
