Description

Technical Field

[0001] The invention relates to the field of mechanical design, in particular to a high-precision transmission disc. Background Art

[0002] In mechanical automation processing, a transmission disc is often used to facilitate the feeding or discharging of materials on it. Common transmission discs usually include a fixed seat, a turntable and a power mechanism. The turntable is rotatably mounted on the fixed seat, and the power mechanism drives the turntable to rotate. When this type of transmission disc is in use, the material can be fixed on the turntable, and the position of the material can be changed by the rotation of the turntable to achieve the feeding or discharging of the material.

[0003] In common transmission discs, the power mechanism usually relies on a gear set to drive the turntable to rotate. However, on the one hand, there is a certain gap in the meshing between the gears in the gear set. On the other hand, due to the large mass of the turntable, the inertia of the turntable during rotation is very large. When the turntable stops instantly after rotating, the turntable will often continue to deflect to a certain extent under the action of inertia, making it difficult for the material to accurately reach the required position, and the movement accuracy is low, making it difficult to meet the needs of high-precision automated processing. Summary of the invention

[0004] The object of the present invention is to provide a high-precision transmission disc that can solve one or more of the above problems.

[0005] According to one aspect of the present invention, there is provided a high-precision transmission disk, comprising a turntable, a base, an oil cylinder, an air cylinder, a connecting block and a clamping block, wherein the oil cylinder is mounted on the base, the air cylinder is mounted on the connecting block, the oil cylinder is hinged to the connecting block, the turntable is provided with a clamping slot, there are a plurality of the clamping slots, the plurality of the clamping slots are evenly distributed in a ring shape around the center of the turntable, the clamping block is connected to the air cylinder, the turntable is mounted on the base, and the clamping block can extend into any of the clamping slots.

[0006] The beneficial effects of the present invention are as follows: in the present invention, the oil cylinder can push the cylinder to move through the connecting block, and because the block installed on the cylinder is embedded in the slot, when the cylinder moves, it can also push the turntable to move through the block, and when the oil cylinder performs a stroke movement, the cylinder can disengage the block from the current slot, and then the oil cylinder resets to drive the cylinder reset, so that the block reaches another slot, and then the cylinder drives the block to be stuck in a new slot, and the above actions are repeated continuously to realize the rotation of the turntable. In the present invention, the block is embedded in the slot to drive the turntable to rotate, and the gap between them is small and the fit is tight. Even if the turntable is subjected to a large rotational inertia when it stops, it is not easy to deflect. Therefore, the present invention has high action accuracy and transmission accuracy, and strong working reliability.

[0007] In some embodiments, the present invention further comprises a guide block, the turntable is provided with an annular guide groove, the guide block is embedded in the annular guide groove, and the guide block is connected to the connecting block. The setting of the guide block and the guide groove, on the one hand, when the cylinder drives the turntable to rotate, it can serve as a guide for the cylinder movement to ensure that the cylinder can effectively drive the turntable to rotate, and on the other hand, when the cylinder retracts, since the block is not stuck in the slot at this time, the guide block and the guide groove can prevent the cylinder from moving too far away from the turntable and serve as a guide for the cylinder to return to the original position.

[0008] In some embodiments, the cylinder includes a cylinder barrel, a cylinder piston rod, a cylinder front cover and a cylinder rear cover, the cylinder barrel is mounted on one end of the cylinder piston rod, one end of the cylinder barrel is connected to the cylinder front cover, and the other end is connected to the cylinder rear cover, and the other end of the cylinder piston rod passes through the cylinder front cover and is hinged to the connecting block.

[0009] In some embodiments, the connecting block includes a pin, a connecting plate, an extension plate and a hinge, wherein the hinge is connected to the oil cylinder piston rod, the extension plate is mounted on the connecting plate, and the hinge is connected to the extension plate via a pin. Thus, the hinge and the extension plate can rotate to a certain extent, so that they can adapt to the rotation of the turntable.

[0010] In some embodiments, a cylinder seat is provided on the base, an extension shaft is provided on the front cover of the cylinder, and the extension shaft is installed in the cylinder seat through a bearing. Since the cylinder will make a certain bending movement when moving with the turntable, if the cylinder is always in a fixed state, it is easy to cause a dead point in the process of driving the cylinder, causing damage to the cylinder or the cylinder. Through the above arrangement, the cylinder can swing on the cylinder seat to a certain extent with the movement of the cylinder, avoiding the generation of dead points and improving the working reliability of the present invention.

[0011] In some embodiments, the cylinder includes a cylinder barrel, a cylinder piston rod, a cylinder front cover, a cylinder rear cover, a front rod sleeve, a rear rod sleeve, a front cover plate and a rear cover plate, the cylinder barrel is sleeved on the cylinder piston rod, one end of the cylinder barrel is connected to the cylinder front cover, and the other end is connected to the cylinder rear cover, the front cover plate is sleeved on the cylinder piston rod and connected to the cylinder front cover, the rear cover plate is sleeved on the cylinder piston rod and connected to the cylinder rear cover, the front rod sleeve is sleeved on the cylinder piston rod and embedded in the cylinder front cover, and the rear rod sleeve is sleeved on the cylinder piston rod and embedded in the cylinder rear cover.

[0012] In some embodiments, the distance between adjacent slots matches the stroke of the oil cylinder. Thus, when the oil cylinder performs a stroke action, the position of the previous slot can just reach the position of the next slot, so that after the oil cylinder is reset, the card block can enter the new slot from the same position, which can avoid the card block being unable to be effectively embedded in the new slot, thereby ensuring the reliability of the action of the present invention.

[0013] In some embodiments, the turntable includes a transmission turntable, a working turntable, a shaft sleeve, a shaft seat and a main shaft, the shaft seat is mounted on the base, the main shaft is fixedly mounted on the shaft seat, the shaft sleeve is rotatably mounted on the main shaft, the transmission turntable and the working turntable are both fixedly mounted on the shaft sleeve, and all the slots are arranged on the side of the transmission turntable. Thus, the transmission turntable and the working turntable can realize synchronous rotation on the main shaft through the shaft sleeve, and the turntable is divided into a transmission turntable and a working turntable, which can make the transmission turntable as a power miniaturized to reduce the required stroke of the oil cylinder.

[0014] In some embodiments, the working turntable includes a working turntable body and reinforcing ribs, the working turntable body is fixedly sleeved on the shaft sleeve, and the reinforcing ribs are connected to the working turntable body and the shaft sleeve. The provision of the reinforcing ribs can improve the connection strength between the working turntable body and the shaft sleeve.

[0015] In some embodiments, a material trough is provided on the top surface of the working turntable body, and the material trough is multiple, the number of the material troughs is equal to the number of the card slots, and the positions of the multiple material troughs and the positions of the multiple card slots are matched one by one. The setting of the material trough can facilitate the placement of materials, and because the movement distance of the turntable each time in the present invention corresponds to the distance between adjacent card slots, the position of the material trough matches the position of the card slot, so that after each turntable movement, the next material trough can move to the position of the previous material trough, avoiding the need to reposition the material on the material trough for subsequent processing, which can effectively improve the processing efficiency of the material on the material trough.

[0035] When the present invention is in use, the material can be placed on the material trough 123 on the working turntable body 121. When the turntable 1 needs to rotate, the oil cylinder 3 can be started, and the oil cylinder piston rod 32 of the oil cylinder 3 extends, and the oil cylinder piston rod 32 drives the cylinder 4 to move through the connecting block 5. At this time, since the cylinder piston rod 42 of the cylinder 4 is connected to the block 6, the cylinder 4 moves, which will drive the block 6 to move together, and since the block 6 is embedded in the slot 101, the block 6 will drive the transmission turntable 11 to move when it moves, so that the transmission turntable 11 rotates around the main shaft 15, and the transmission turntable 11 can make the working turntable 12 rotate synchronously through the shaft sleeve 13.

[0036] When the turntable 1 rotates to the right position, that is, the cylinder piston rod 32 of the cylinder 3 is extended to the right position, the cylinder 4 can be started to make the cylinder piston rod 42 of the cylinder 4 retract, that is, the blocking block 6 is disengaged from the slot 101, and then the cylinder 3 is started again to make the cylinder piston rod 32 retract, so that the cylinder 4 is pulled and moved by the cylinder piston rod 32. When the cylinder piston rod 32 returns to its original position, the cylinder 4 also returns to its original position, that is, the cylinder piston rod 42 can face the new slot 101 again, and the cylinder 4 is started again to make the cylinder piston rod 42 extend, and the blocking block 6 is embedded in the new slot 101.

[0037] In addition, when the cylinder 4 moves forward or backward as the cylinder piston rod 32 of the oil cylinder 3 extends or retracts, the guide block 7 moves along the annular guide groove 102, that is, the movement of the cylinder 4 can be restricted by the guide block 7 and the annular guide groove 102, thereby ensuring its movement accuracy.

[0038] By repeating the above process, the oil cylinder 3 can continuously push the turntable 1 to rotate, so as to realize the feeding or discharging of materials. In the present invention, the block 6 is embedded in the slot 101 to drive the turntable to rotate. Compared with the traditional gear drive, the gap between them is small and the fit is tight. Even if the turntable 1 is subjected to a large rotation inertia when it stops, it is not easy to deflect. Therefore, the present invention has high action accuracy and transmission accuracy and strong working reliability.

[0039] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
