Description

Technical Field

[0001] This utility model relates to the field of coupling alignment tooling technology, specifically a special tooling for aligning and centering belt conveyor couplings. Background Technology

[0002] A coupling is a device that connects two shafts or a shaft and a rotating component, allowing them to rotate together during motion and power transmission. Under normal circumstances, they do not disengage. Sometimes, they are also used as a safety device to prevent the connected components from bearing excessive loads, thus providing overload protection. If the coupling is not aligned to the specified accuracy, it will inevitably cause abnormal vibration of the equipment, resulting in bearing temperature rise, bearing wear, and other adverse phenomena, affecting the safe operation of the equipment. In severe cases, it may even cause equipment accidents. Therefore, the shaft center alignment of the mechanical equipment must be performed during each equipment maintenance to ensure that the center deviation of the two shafts does not exceed the specified value.

[0003] Chinese Patent Publication No. CN215177490U discloses a special fixture for aligning couplings, comprising a pump-side half-coupling and a motor-side half-coupling, and a motor. A T-shaped clamp is fixedly connected to the outer wall of the pump-side half-coupling, and an L-shaped clamp is inserted into one end of the T-shaped clamp. The T-shaped clamp and the L-shaped clamp form a special fixture. One side of the L-shaped clamp is connected to one side of the motor-side half-coupling. A dial indicator 1, a dial indicator 2, and a dial indicator 3 are installed on the outer wall of the L-shaped clamp. One end of the motor-side half-coupling is fixedly connected to the output shaft of the motor.

[0004] However, the inventor of the above device believes that there are certain defects. The T-type clamp in the above device is fixed. Since the spacing of the couplings of different units is different, the device is not easy to set up when the spacing is large or small, which affects the inspection of the coupling. Therefore, this utility model provides a special tooling for aligning and aligning belt conveyor couplings. Utility Model Content

[0005] The purpose of this utility model is to provide a special tooling for aligning and aligning belt conveyor couplings, so as to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a special tooling for aligning and centering belt conveyor couplings, comprising a first coupling, a second coupling, and a mounting base. The mounting base is connected to the second coupling via a fixing component. A sliding seat is mounted on the mounting base, and a movable rod is mounted on the top of the sliding seat. The movable rod is mounted on the top of the sliding seat via a hinge. The bottom of the movable rod and one side of the sliding seat are connected via an elastic component. The movable rod is pressed against the top of the sliding seat by the elastic component. A dial indicator is mounted on one end of the movable rod. The sliding seat slides on the top of the mounting base, and a limiting component is provided inside the sliding seat to restrict the sliding of the sliding seat on the top of the mounting base.

[0007] Preferably, the top of the mounting base is provided with a top sliding groove, and the bottom of the sliding seat slides inside the top sliding groove, so that the sliding seat slides on the top of the mounting base through the top sliding groove.

[0008] Preferably, the limiting mechanism includes a sliding rod that slides inside the sliding seat, and a fixed insertion hole is provided on the inner bottom wall of the top sliding groove. One end of the sliding rod is located in the fixed insertion hole, and the sliding seat is limited to slide inside the top sliding groove by inserting one end of the sliding rod into the fixed insertion hole.

[0009] Preferably, the sliding seat has an inner cavity, and a fixed baffle is installed on the sliding rod. A return spring is installed at the bottom of the fixed baffle. With the fixed baffle and the return spring, when the top of the sliding rod is not under force, the sliding rod is quickly driven to slide upward, so that one end of the sliding rod is pulled out from the inside of the fixed insertion hole.

[0010] Preferably, the elastic component includes a tension spring, and the movable rod and the sliding seat are connected by the tension spring. Under the action of the tension spring, the movable rod is stably pressed against the top of the sliding seat.

[0011] Preferably, the fixing component includes two sliding clamps, and the bottom of the mounting base is provided with a sliding groove. One end of each of the two sliding clamps slides inside the sliding groove, and a connecting block is installed on one end of each of the two sliding clamps. By driving the two sliding clamps to clamp onto the coupling second, and by inserting the connecting block into the mounting hole of the coupling second, the mounting base is rotated during the rotation of the coupling second.

[0012] Preferably, a bidirectional screw is installed inside the sliding groove, and the other ends of the two sliding clamps are threaded onto the bidirectional screw. The two sliding clamps are driven to move closer or further apart by rotating the bidirectional screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application uses a fixing component to fix the mounting base to the second coupling, so that the dial indicator's contact presses against the first coupling and records the data. By driving the second coupling to rotate and recording multiple data values ​​from the dial indicator, the corresponding center deviation data of the coupling is obtained for adjustment. Furthermore, a contact limiting mechanism drives the sliding seat to slide horizontally on the top of the mounting base, making it suitable for aligning the first and second couplings with different spans, thus having good practicality.

[0015] 2. This application uses a tension spring to press one end of the movable rod against the top of the sliding seat, thereby pressing the movable rod against the top of the sliding insert rod. This allows one end of the sliding insert rod to be stably inserted into the fixed insertion hole, thus restricting the sliding seat from sliding inside the top sliding groove. By rotating the bidirectional screw, the two sliding clamps are brought closer together, and the two connecting blocks are inserted into the mounting holes inside the coupling two, thereby fixing the mounting seat as a whole onto the coupling two.

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.

[0022] Please see Figure 1 , Figure 2, Figure 3 and Figure 4 A special tooling for aligning and centering belt conveyor couplings includes a first coupling 1, a second coupling 2, and a mounting base 3. The mounting base 3 is connected to the second coupling 2 via a fixing assembly, which includes two sliding clamps 8. A sliding groove is formed at the bottom of the mounting base 3, and one end of each of the two sliding clamps 8 slides within the sliding groove. The bottom of the mounting base 3 is arc-shaped. By driving the two sliding clamps 8 closer together, the two sliding clamps 8 clamp onto the mounting plate of the second coupling 2, thus mounting the mounting base 3 onto the mounting plate of the second coupling 2.

[0023] Please refer to it again. Figure 1 and Figure 3 Each of the two sliding clamps 8 has a connecting block 9 installed at one end. A bidirectional screw 10 is installed inside the sliding groove. The other ends of the two sliding clamps 8 are threaded onto the bidirectional screw 10. The connecting block 9 is fixedly connected to one end of the sliding clamp 8. When the two sliding clamps 8 approach each other, the connecting block 9 is inserted into the mounting hole of the coupling 2. The bidirectional screw 10 is a screw with two external threads. The threads of the two external threads are opposite in direction. By driving the bidirectional screw 10 to rotate, the two sliding clamps 8 slide closer to each other or further away from each other.

[0024] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 A sliding seat 4 is installed on the mounting base 3. The sliding seat 4 slides on the top of the mounting base 3. A top sliding groove 31 is provided on the top of the mounting base 3. The bottom of the sliding seat 4 slides inside the top sliding groove 31. Both the top sliding groove 31 and the bottom of the sliding seat 4 are T-shaped.

[0025] Please refer to it again. Figure 1 , Figure 2 and Figure 4 A movable rod 5 is installed on the top of the sliding seat 4. The movable rod 5 is installed on the top of the sliding seat 4 via a hinge. A dial indicator 6 is installed on one end of the movable rod 5. The movable rod 5 is installed on the top of the sliding seat 4 via the hinge. By flipping the movable rod 5, the contact of the dial indicator 6 is pressed against the mounting plate of the coupling-1 for testing.

[0026] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4The sliding seat 4 is provided with a limiting component inside to restrict the sliding of the sliding seat 4 on the top of the mounting seat 3. The limiting mechanism includes a sliding rod 41 that slides inside the sliding seat 4. A fixed insertion hole 32 is provided on the inner bottom wall of the top sliding groove 31. One end of the sliding rod 41 is located in the fixed insertion hole 32. The sliding rod 41 is inserted into the fixed insertion hole 32 to restrict the sliding of the sliding seat 4 inside the top sliding groove 31. The movable rod 5 presses on the top of the sliding rod 41 so that one end of the sliding rod 41 is stably inserted into the fixed insertion hole 32.

[0027] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The sliding seat 4 has an inner cavity 42. A fixed baffle 43 is installed on the sliding rod 41. The fixed baffle 43 is fixedly connected to the outer surface of the sliding rod 41 and is located inside the inner cavity 42. A return spring 44 is installed at the bottom of the fixed baffle 43. The return spring 44 is sleeved on the outer surface of the sliding rod 41. When the top of the sliding rod 41 is not under force, the return spring 44 causes the sliding rod 41 to slide upward, so that one end of the sliding rod 41 is pulled out from the inside of the fixed insertion hole 32. The elastic component includes a tension spring 7. The movable rod 5 is connected to the sliding seat 4 through the tension spring 7. Under the action of the tension spring 7, the movable rod 5 is stably pressed on the top of the sliding seat 4.

[0028] Working principle: By installing the mounting base 3 on the mounting plate of coupling 2, the connecting block 9 on the side of the sliding clamp 8 is aligned with the mounting hole on the mounting plate. Rotating the double-acting screw 10 drives the two sliding clamps 8 closer together, clamping them onto the mounting plate of coupling 2. The connecting block 9 is inserted into the mounting hole of the mounting plate to complete the installation and fixation of the mounting base 3. By flipping the movable rod 5, the sliding rod 41 is pushed out of the fixed insertion hole 32 by the spring force of the return spring 44, allowing the sliding seat 4 to slide inside the top sliding groove 31 to adjust the distance between the dial indicator 6 and coupling 1. After adjustment, the screw is released. The tension of the movable rod 5, under the action of the tension spring 7, causes the movable rod 5 to press against the top of the sliding seat 4. The movable rod 5 pushes the sliding insert rod 41 to slide downward, so that one end of the sliding insert rod 41 is inserted into the interior of the fixed insertion hole 32 to restrict the sliding seat 4 from sliding inside the top sliding groove 31. The contact of the dial indicator 6 presses against the mounting plate surface of the coupling 1 to record the data value. By driving the rotor of the coupling 2 to rotate, the data is read once every 90° rotation. After four rotations, the center deviation data of the two corresponding couplings is calculated by the four readings of the dial indicator 6. Then, according to the requirements of the coupling center, the alignment requirements are finally achieved through reasonable adjustment methods.

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.
