Description

Technical Field

[0001] This invention belongs to the technical field of clutch connection structures, specifically relating to a connection structure between the clutch braking end and the upper crossbeam. Background Technology

[0002] Since most mechanical presses operate in a single stroke and require inching adjustments or mold maintenance, the press's braking system must be reliable. The function of the brake is to quickly stop the driven part after it is disengaged from the power source. Braking systems can be either pneumatic or spring-loaded.

[0003] Spring brakes offer the highest reliability, as they use spring force to press the friction plates or blocks to a stationary position. Therefore, a component in the brake assembly must be fixed to the upper crossbeam and remain stationary. In traditional dry, split-type floating insert clutches, the clutch and brake ends are separate. The brake end has a support plate, on which the brake is mounted, and the support plate is fixed to the machine tool's crossbeam. The support plate serves two purposes: firstly, it houses the bearings, providing a fulcrum for the flywheel shaft; secondly, it acts as a bridge connecting the brake end and the upper crossbeam. However, to match the brake's mounting dimensions, the support plate also needs to be large. As the braking torque increases, this support plate adds to the machine tool's weight, increasing manufacturing costs and hindering the company's competitiveness. Furthermore, the manufacturing and installation process is cumbersome. Summary of the Invention

[0004] This invention relates to a connection structure between a clutch braking end and an upper crossbeam, comprising a flywheel shaft, a braking end, a connecting mechanism for the upper crossbeam and the braking end, wherein the upper crossbeam is provided on the outer side of one end of the flywheel shaft, and the left end of the connecting upper crossbeam is connected to the braking end via the braking end connecting mechanism. The braking end includes a brake body, a brake inner diameter plate, a friction block, a brake cylinder, a brake spring, a brake piston, a diaphragm, a brake pressure plate, and a piston connecting mechanism. The connecting upper crossbeam includes an upper crossbeam, an upper crossbeam ring, an upper crossbeam bearing, a pressure cap, a collar, a rotary oil seal, a self-aligning bearing, and a keyway. The braking end connecting mechanism includes a locking nut, a keyway, and a... The expansion sleeve, and the piston connection mechanism, include an outer ring, an inner ring, a sleeve, a double-ended screw, and a lock nut. In this invention, the upper crossbeam and brake body are fixed in two layers. The first layer uses a flat key to connect the upper crossbeam and brake body, preventing rotation and ensuring the brake body remains stationary in the circumferential direction. The second layer uses a single bolt to connect the brake body and the upper crossbeam ring, ensuring stationary in the end face direction. The brake inner diameter plate has a two-layer anti-loosening mechanism for radial positioning. The first layer relies on the threaded connection between the locking nut and the flywheel shaft to press the brake inner diameter plate, thus preventing loosening. The second layer uses a flat key and bolts to lock the locking nut and flywheel shaft, ensuring the locking nut does not slip. This prevents the brake inner diameter plate from shaking and roaming, causing impact damage to other parts, should the expansion sleeve loosen and fail.

[0005] The upper crossbeam ring and the upper crossbeam bearing seat are concentrically located on the surface of the upper crossbeam. A flywheel shaft is located at the center of the upper crossbeam ring and the upper crossbeam bearing seat. The center of the upper crossbeam bearing seat is connected to the flywheel shaft via a self-aligning bearing. A pressure cap is located on the outer left side of the upper crossbeam bearing seat. The pressure cap is disc-shaped, and its center is connected to the flywheel shaft via a collar. The center of the pressure cap is also connected to the collar via a rotary oil seal. The left side of the collar is connected to the braking end, and the braking end is connected to the collar via a braking end connecting mechanism. The self-aligning bearing and the pressure cap are directly mounted on the upper crossbeam bearing seat, thus ensuring the reliability of the flywheel shaft support.

[0006] The brake body is shaped like a shelled cylinder. The right end of the brake body connects to the upper crossbeam ring, which has a machined stop. This ensures a small clearance fit circumferentially and a stepped positioning at the end face when the brake body and upper crossbeam ring are installed, guaranteeing smooth installation. A brake cylinder is located at the left end of the brake body. A brake pressure plate is located on the left side of the brake body's interior, and a brake inner diameter plate is located on the right side of the brake pressure plate. A brake spring is located between the brake pressure plate and the brake cylinder. The right side of the brake inner diameter plate connects to the left side of the collar. A friction block is located inside the outer edge of the brake inner diameter plate. A brake piston is located on the outer side of the left end of the brake cylinder. A diaphragm is located between the brake piston and the brake cylinder. The brake piston is connected to the brake cylinder via a piston connecting mechanism. When the brake cylinder is not inlet air, the compressed brake spring moves to the right. The spring force pushes the brake piston and brake pressure plate to the right, pressing against the friction block, thus braking the brake inner diameter plate and flywheel shaft. When the brake cylinder receives air, compressed air enters the sealed chamber between the diaphragm and the brake cylinder, overcoming the brake spring force and pushing the brake piston and brake pressure plate to move to the left. The brake pressure plate then disengages from the friction block. When air is released from the clutch, the flywheel rotates, causing the flywheel shaft to rotate as well.

[0007] The expansion sleeve is located on the outside of the brake inner diameter plate. The left end of the expansion sleeve is flush with the left end of the brake inner diameter plate. The left end of the expansion sleeve is provided with a locking nut. The center of the locking nut is connected to the outside of the flywheel shaft through a thread. The left end of the flywheel shaft is provided with a flat key.

[0008] The brake piston has an outer ring along its inner outer edge and an inner ring along its inner inner edge. The outer ring is connected to the brake cylinder on its outer side and to the brake piston on its inner end. The inner ring is connected to the brake piston on its outer end and to the brake cylinder on its inner end. The inner ring has several sleeves on its surface. One end of each sleeve is connected to the brake piston, and the other end is connected to the brake cylinder. A double-ended screw is installed inside each sleeve. The double-ended screw passes through the sleeve, with one end penetrating the brake piston and the other end located inside the brake cylinder. The upper crossbeam ring and the upper crossbeam bearing are also fixed to the upper crossbeam. The brake body is fixed to the upper crossbeam ring. The inner ring, outer ring, diaphragm, and brake cylinder are connected together by bolts. The brake cylinder is also bolted to the brake body. Therefore, the brake body, inner ring, outer ring, diaphragm, and brake cylinder are all in a stationary state.

[0009] There is an installation gap between the brake pressure plate and the brake cylinder, and there is an installation gap between the brake inner diameter plate and the brake body. Only with sufficient installation gap can the brake end effectively brake the flywheel shaft. Without installation gap, the brake end will be directly driven to rotate, thus failing to achieve the desired braking effect.

[0010] An annular oil return groove is provided between the gland and the self-aligning bearing. An oil return hole is provided on the left side of the self-aligning bearing. An annular oil groove is provided on the upper crossbeam bearing seat. These features serve to store oil and ensure that excess lubricating oil after lubricating the self-aligning bearing can return to the upper crossbeam in a timely manner through the oil return hole, preventing it from accumulating around the gland and causing oil leakage.

[0011] The upper crossbeam ring and the upper crossbeam bearing are connected to the upper crossbeam by welding, ensuring that the upper crossbeam ring and the upper crossbeam bearing have sufficient fixing strength, thereby ensuring that the brake end fixed on the upper crossbeam ring has sufficient strength to prevent damage during high-speed rotation and braking.

[0012] Beneficial effects:

[0013] In this invention, the upper crossbeam and brake body are fixed in two layers. The first layer uses a flat key to connect the upper crossbeam and brake body, preventing rotation and ensuring the brake body remains stationary in the circumferential direction. The second layer uses a ring of bolts to connect the brake body and the upper crossbeam ring, ensuring stationary end face direction. The brake inner diameter plate has a two-layer anti-loosening mechanism for radial positioning. The first layer relies on the threaded connection between the locking nut and the flywheel shaft to press the brake inner diameter plate, thus preventing loosening. The second layer uses a flat key and bolts to lock the locking nut and flywheel shaft, ensuring the locking nut does not slip. This prevents the brake inner diameter plate from shaking and roaming, causing impact damage to other parts, should the expansion sleeve loosen and fail. Attached Figure Description

[0024] Implementation example;

[0025] After the self-aligning bearing 12 and the flywheel shaft 5 are assembled, they are inserted into the upper crossbeam. The brake body 2 is fixed to the upper crossbeam ring 1 by bolts and key 7. The collar 4 is installed on the flywheel shaft 5 and presses against the self-aligning bearing 12. The pressure cap 3 is fixed to the upper crossbeam shaft seat 24 by bolts 29. The rotating oil seal 10 is installed into the pressure cap 3. Then, the brake inner diameter plate 9, friction block 13, and expansion sleeve 8 are installed in sequence. The locking nut 6 is threaded to the flywheel shaft 5 and presses against the brake inner diameter plate 9. The key 7 connects the locking nut 6 and the flywheel shaft 5. The double-ended screw 21 is screwed into the brake pressure plate 23 and then installed into the brake body 2. The brake pressure plate 23 presses against the friction block 13. After the brake cylinder 14 and the brake spring are assembled, they are connected to the brake body 2 by bolts 29. Then, the sleeve 20, diaphragm 17, inner ring 19, outer ring 15, brake piston 18, and anti-loosening nut 22 are installed in sequence.

[0026] When brake cylinder 14 is not receiving air, the compressed brake spring moves to the right. The spring force pushes brake piston 18 and brake pressure plate 23 to the right, pressing against friction block 13, thus braking the inner brake plate 9 and flywheel shaft 5. When brake cylinder 14 receives air, compressed air enters the sealed chamber of diaphragm 17 and brake cylinder 14, overcoming the brake spring force and pushing brake piston 18 and brake pressure plate 23 to the left. Subsequently, brake pressure plate 23 disengages from friction block 13. After air is supplied to the clutch, the flywheel rotates, causing flywheel shaft 5 to rotate as well.

[0027] The upper crossbeam and brake body 2 are fixed in two layers. The first layer uses a flat key 7 to connect the upper crossbeam and brake body 2, which serves to prevent rotation and ensure the circumferential direction of the brake body 2 remains stationary. The second layer uses a ring of bolts 29 to connect the brake body 2 and the upper crossbeam ring 1, ensuring the end face remains stationary. In this invention, the radial positioning of the brake inner diameter plate 9 has two layers of anti-loosening mechanisms. The first layer relies on the threaded connection between the locking nut 6 and the flywheel shaft 5 to press the brake inner diameter plate 9, thus preventing loosening. The second layer uses a flat key 7 to lock the locking nut 6 and the flywheel shaft 5 with bolts 29, ensuring that the locking nut 6 does not slip. This prevents the brake inner diameter plate 9 from shaking and moving around after the expansion sleeve 8 loosens and fails, thus preventing impact damage to other parts.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
