Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to a shaft auxiliary assembly device. Background Technology

[0002] The output shaft of a speed reducer is an important component. Its main function is to output the mechanical power transmitted inside the speed reducer to the load, driving the relevant mechanical equipment to operate. The output shaft is usually connected to the load equipment (such as motors, gears, couplings, etc.) to transmit power and control the operation of the equipment.

[0003] Traditionally, the output shaft of a speed reducer is installed using a keyed connection. For example, a keyway is set on the arc surface of the shaft, a key is assembled onto the keyway shaft, and finally the shaft is inserted into the mounting hole of the shaft through an overfit. However, in actual use, it has been found that the overfit of the keyed connection of the output shaft will cause frictional damage to the shaft or the internal assembly position of the speed reducer, thus affecting the normal use of the equipment. Moreover, disassembling the shaft is very difficult and inconvenient, affecting the ease of use. Utility Model Content

[0004] The technical problem this invention aims to solve is that after connecting a large number of cables to the surface of the display screen, these cables are prone to getting tangled with the bracket, which in turn affects the subsequent angle adjustment of the bracket.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a shaft auxiliary assembly device, including an auxiliary device, wherein the auxiliary device uses an outer ring block and an inner ring block to conveniently and quickly install and fix the output shaft at the assembly position of the reducer.

[0006] The effect achieved by the above components is as follows: when the reducer is in use and the output shaft is assembled and fixed, the auxiliary device is first installed on the arc surface of the shaft, then the shaft and the auxiliary device are moved to the assembly position of the reducer, and then the auxiliary device is operated to fix the position of the shaft.

[0007] Preferably, the auxiliary device includes a ring, wherein four outer ring blocks are provided on the inner wall of the ring, and an inner ring block is installed near the outer ring blocks. Fixed rings are provided on both sides of the ring, wherein the fixed rings are located on the side where the outer ring blocks and the inner ring blocks are close to each other. Four threaded rods are provided through both fixed rings, wherein nuts are threadedly connected to the arc surfaces at both ends of the threaded rods.

[0008] The effect achieved by the above components is that the position of the shaft is fixed, which makes it more convenient and quick to install and fix the output shaft of the reducer, and it is less likely to cause damage to the equipment or the surface of the shaft. It also makes it easier to inspect and maintain the position later, and improves the convenience of using the output shaft.

[0009] Preferably, the surfaces of the four outer ring blocks and inner ring blocks are respectively provided with connecting grooves, and a connecting post is installed in the connecting groove of one outer ring block and one inner ring block that are close to each other.

[0010] The effect achieved by the above components is that, through the setting of the connecting groove, the four outer ring blocks and the four inner ring blocks form a one-to-one corresponding connection, thereby allowing the shaft to be assembled into the internal position of the reducer more quickly during use, forming a certain overall relationship.

[0011] Preferably, reinforcing grooves are formed on both sides of the surface of the four outer ring blocks, and an arc-shaped rod is provided on the inner wall of the reinforcing groove.

[0012] The effect achieved by the above components is that, through the setting of reinforcing grooves and arc-shaped rods, a certain connection relationship is formed between the four outer ring blocks, connecting them into a whole, which is not easy to loosen and ensures the integrity of the device.

[0013] Preferably, a spring is installed at one end of the connecting post, wherein the other end of the spring is connected to the inner wall of the outer ring block.

[0014] The effect achieved by the above components is that, through the setting of the spring, the connecting column slides on the inner wall of the connecting groove under the elastic force of the spring, thereby stably opening the gap between the outer ring block and the inner ring block, facilitating the use of the ring.

[0015] Preferably, the auxiliary device further includes a reinforcing pad installed on the inner wall of the inner ring block, and washers are respectively fitted on the arc surfaces at both ends of the threaded rod, wherein the reinforcing pad and washers enhance the limiting effect of the inner ring block and the nut.

[0016] The effects achieved by the above components are as follows: the rubber gaskets and reinforcing pads make the inner ring block fit more closely when it contacts and presses against the arc surface of the shaft, making the nut and the retaining ring more stable, and further increasing the friction, thereby making the shaft assembly more secure.

[0017] Preferably, a reinforcing block is fixedly connected to the arc surface of each of the four outer ring blocks, wherein the reinforcing block is inserted into a slot on the surface of the ring.

[0018] The effect achieved by the above components is that, by setting the reinforcing blocks, when the outer ring block is opened, the reinforcing blocks on the surface of the outer ring block are pressed against the inner wall of the reducer assembly position, thereby further improving the limiting effect of the outer ring block.

[0019] Preferably, a plurality of uniformly circumferentially distributed limiting plates are fixedly connected to both sides of the surface of the ring, wherein the limiting plates ensure the stability of the position of the components on the inner wall of the ring.

[0020] The effect achieved by the above components is that, by setting the limiting plate, the positions of the outer ring block and the inner ring block on the inner wall of the ring are more stable and less likely to shift from the inner wall of the ring, thereby ensuring the normal use of the auxiliary device.

[0021] The beneficial effects of this utility model are:

[0022] The present invention makes the installation and fixing of the output shaft of the reducer more convenient and quick, and is less likely to cause damage to the equipment or shaft surface. It also makes it easier to locate the position for later maintenance and improves the convenience of using the output shaft. Attached Figure Description

[0031] Figure 1 and Figure 2 The shaft auxiliary assembly device shown includes an auxiliary device 1, which uses an outer ring block 102 and an inner ring block 103 to conveniently and quickly install and fix the output shaft at the assembly position of the reducer.

[0032] Figures 1-4 The auxiliary device 1 shown includes a ring 101, with four outer ring blocks 102 arranged on the inner wall of the ring 101. An inner ring block 103 is installed near the outer ring blocks 102. Fixed rings 104 are arranged on both sides of the ring 101, with the fixed rings 104 located on the side where the outer ring blocks 102 and inner ring blocks 103 are close to each other. Four threaded rods 105 are threaded through both fixed rings 104. Nuts 106 are threaded onto the arc surfaces at both ends of the threaded rods 105. When the reducer is in use and the output shaft is assembled and fixed, firstly, the four inner ring blocks 103 are wrapped around the arc surface of the shaft. Then, the shaft and the rubber ring 101 are moved to the inner wall position of the reducer assembly. At this time, the outer ring blocks 102 and inner ring blocks 103 are located inside the ring 101. Then, the two… The retaining rings 104 are pressed against the gaps on both sides formed by the inner ring block 103 and the outer ring block 102. Then, the four threaded rods 105 are passed through the surfaces of the two retaining rings 104. Finally, the two nuts 106 are threaded onto the arc surfaces at both ends of the threaded rods 105, so that the nuts 106 contact and compress the retaining rings 104. At this time, the gap between the inner ring block 103 and the outer ring block 102 will gradually increase. The ring block formed by the four inner ring blocks 103 will compress and cover the arc surface of the shaft, while the ring block formed by the four outer ring blocks 102 will drive the ring 101 to press against the inner wall of the installation. At this time, the position of the shaft is fixed. This makes it more convenient and faster to install and fix the output shaft of the reducer, and it is less likely to cause damage to the equipment or shaft surface. It also facilitates the later maintenance position and improves the convenience of using the output shaft.

[0033] Figures 1-4The four outer ring blocks 102 and the inner ring blocks 103 shown are respectively provided with connecting grooves 1011. A connecting post 1012 is installed in the connecting grooves 1011 of one outer ring block 102 and one inner ring block 103 that are close to each other. Through the setting of the connecting grooves 1011, the four outer ring blocks 102 and the four inner ring blocks 103 form a one-to-one corresponding connection relationship. In use, the shaft can be assembled into the internal position of the reducer more quickly and form a certain integral relationship. The four outer ring blocks 102 are respectively provided with reinforcing grooves 1014 on both sides of their surfaces. The inner wall of the reinforcing grooves 1014 is provided with arc-shaped rods 1015. Through the setting of the reinforcing grooves 1014 and the arc-shaped rods 1015, the four outer ring blocks 102 are connected to each other and connected into a whole. It is not easy to loosen and ensures the integrity of the device.

[0034] Figures 1-4 A spring 1013 is installed at one end of the connecting post 1012 shown, and the other end of the spring 1013 is connected to the inner wall of the outer ring block 102. The spring 1013 allows the connecting post 1012 to slide against the inner wall of the connecting groove 1011 under the elastic force of the spring 1013, thereby stably opening the gap between the outer ring block 102 and the inner ring block 103, facilitating the use of the ring 101. The auxiliary device 1 also includes a reinforcing pad installed on the inner wall of the inner ring block 103. 109. Washers 1016 are respectively fitted on the arc surfaces at both ends of the threaded rod 105. The reinforcing washer 109 and washer 1016 enhance the limiting effect of the inner ring block 103 and nut 106. With the rubber washer 1016 and reinforcing washer 109, the inner ring block 103 is more closely fitted when it contacts and presses against the arc surface of the shaft, and the nut 106 and the fixing ring 104 are more stable, and the friction is further improved, so that the assembly of the shaft is more stable.

[0035] Figures 1-4 Reinforcing blocks 108 are fixedly connected to the arc surfaces of the four outer ring blocks 102 shown. The reinforcing blocks 108 are inserted into the slots 107 on the surface of the ring 101. By setting the reinforcing blocks 108, when the ring 101 is opened, the reinforcing blocks 108 on the surface of the outer ring blocks 102 are pressed against the inner wall of the reducer assembly position, thereby further improving the limiting effect of the outer ring blocks 102. Several evenly circumferentially distributed limiting plates 1017 are fixedly connected to both sides of the surface of the ring 101. The limiting plates 1017 ensure the stability of the component positions on the inner wall of the ring 101. By setting the limiting plates 1017, the positions of the outer ring blocks 102 and inner ring blocks 103 on the inner wall of the ring 101 are more stable and less likely to shift from the inner wall of the ring 101, thereby ensuring the normal use of the auxiliary device 1.

[0036] Working principle: When the reducer is in use, during the assembly and fixing of the output shaft, firstly, four inner ring blocks 103 are wrapped around the arc surface of the shaft. Then, the shaft and the rubber ring 101 are moved to the inner wall of the reducer assembly. At this time, the outer ring block 102 and the inner ring block 103 are located inside the ring 101. Then, two fixing rings 104 are pressed into the gaps on both sides formed by the inner ring block 103 and the outer ring block 102. Next, four threaded rods 105 are inserted through the surfaces of the two fixing rings 104. Finally, two nuts 106 are threaded onto the threaded rods 104. On the two ends of the arc surface of 5, the nut 106 contacts and presses the fixing ring 104. At this time, the gap between the inner ring block 103 and the outer ring block 102 will gradually increase. The ring block ring composed of the four inner ring blocks 103 will press and cover the arc surface of the shaft, while the ring block ring composed of the four outer ring blocks 102 will drive the ring ring 101 to press against the inner wall of the installation. At this time, the position of the shaft is fixed. When the output shaft of the reducer is installed and fixed, it is more convenient and quick, and it is less likely to cause damage to the equipment or shaft surface. It is also convenient for later maintenance and improves the convenience of using the output shaft.
