Description

Technical Field

[0001] The invention relates to the technical field of robot connection bases, and in particular to an industrial robot connection base which is convenient for adjusting angles. Background Art

[0002] An industrial robot is a multi-joint manipulator or multi-degree-of-freedom machine device for the industrial field. It can perform work automatically and is a machine that relies on its own power and control capabilities to achieve various functions. It can accept human commands or run according to pre-programmed programs. Modern industrial robots can also act according to the principles and guidelines formulated by artificial intelligence technology. An industrial robot requires a connection base when it is installed. In the prior art, the existing industrial robot connection base is inconvenient to adjust the angle of the connection base after installation, resulting in poor use of the robot when working on different production lines.

[0003] After searching, the patent with patent announcement number CN202220370613.4 discloses an industrial robot connection base that is easy to adjust the angle. Although the device increases the stability of the base through the shock-absorbing mechanism when in use to prevent accidents caused by the instability of the base during work, the rotating shaft and turntable can be rotated 360 degrees and can stop at any angle to improve work efficiency. Because the motor is set below, the operation is simple. Through the reset spring, it can quickly return to the original position when not in use, and it has a supporting effect. However, although the device can adjust the angle when in use, it lacks a locking means after the angle adjustment. When the industrial robot is working, if there is no effective locking means after the angle adjustment of the base is completed, the base may change slightly due to external factors (such as vibration), thereby affecting the accuracy and stability of the industrial robot. When the industrial robot is performing high-precision or high-load work, if the angle of the base changes unexpectedly, it may cause the industrial robot to lose control or be damaged, and may even pose a safety threat to the operator. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides an industrial robot connection base that is easy to adjust the angle, thereby solving the problems raised in the background art.

[0005] The solution of the present invention to solve the above technical problems is as follows:

[0006] An industrial robot connection base that is convenient for adjusting the angle comprises a bottom plate, a shell is mounted on the bottom plate, a turntable is rotatably mounted on the shell, and the turntable is used to mount the industrial robot;

[0007] An electric push rod is installed on the bottom plate in the shell, a worm wheel is installed at the output end of the electric push rod, a worm is installed on one side of the worm wheel inside the shell, a servo motor is installed at one end of the worm, the servo motor drives the worm to rotate, the worm and the worm wheel are meshed and driven, a connecting seat is provided on the worm wheel, a transmission shaft is rotatably installed on the top end of the shell, a transmission wheel is provided at the bottom end of the turntable, and the transmission shaft and the transmission wheel are connected through ratchet gear transmission;

[0008] A support seat is installed at the top of the shell, the turntable is rotatably installed on the shell through the support seat, and the transmission shaft and the connecting seat are plugged into each other.

[0009] Based on the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the ratchet teeth are elastically mounted on the fixed disk of the transmission shaft via a torsion spring.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] The ratchet teeth are elastically mounted on the fixed plate of the transmission shaft through a torsion spring. This design allows the ratchet teeth to deflect when subjected to external force, thereby achieving engagement and disengagement with the tooth grooves of the transmission wheel. When the transmission shaft rotates, the ratchet teeth can smoothly engage in the tooth grooves of the transmission wheel, driving the transmission wheel to rotate in one direction. When the external force acts in the opposite direction on the transmission wheel, the ratchet teeth will disengage from the tooth grooves under the action of the torsion spring, thereby preventing the transmission wheel from rotating in the opposite direction. This design not only improves the reliability and stability of the transmission, but also enables the turntable to achieve the function of unidirectional rotation, meeting the specific needs of industrial robots for angle adjustment direction.

[0013] Furthermore, a tooth groove is provided on the inner side of the transmission wheel, and the tooth groove is engaged with the ratchet teeth of the fixed disk, thereby driving the transmission wheel to rotate in one direction through the transmission shaft.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] The tooth grooves on the inner side of the transmission wheel engage with the ratchet teeth of the fixed disk. This design realizes one-way transmission between the transmission shaft and the transmission wheel. When the transmission shaft rotates, the ratchet teeth can smoothly engage with the tooth grooves of the transmission wheel, thereby driving the transmission wheel and the turntable to rotate. Due to the unidirectionality of the ratchet teeth, when an external force acts in the opposite direction on the transmission wheel, the ratchet teeth will disengage from the tooth grooves, preventing the transmission wheel and the turntable from rotating in the opposite direction. This one-way transmission design not only improves the efficiency and stability of the transmission, but also allows the turntable to remain locked when necessary to prevent accidental rotation due to external forces.

[0016] Furthermore, a receiving groove is provided in the connection seat, a key groove is provided above the receiving groove, and a guide block is provided in the receiving groove, and the receiving groove is connected with the key groove through the guide block.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The receiving groove and keyway design in the connecting seat, as well as the guide block set in the receiving groove, enable the key teeth of the main shaft to smoothly enter the keyway through the guide block and achieve a stable connection with the connecting seat. When the electric push rod drives the turbine to rise and fall, the connecting seat will also rise and fall accordingly, and then the keyway will cooperate with the key teeth of the main shaft to realize the rotation drive of the transmission shaft. This design not only improves the accuracy and stability of the transmission, but also makes the angle adjustment of the turntable more flexible and controllable. At the same time, the design of the guide block also plays a guiding and positioning role, ensuring that the key teeth can accurately enter the keyway, avoiding the problem of transmission failure caused by improper installation.

[0019] Furthermore, a main shaft is provided at the bottom end of the fixed disk, and key teeth are provided on the main shaft. The main shaft cooperates with the key slot of the connecting seat through the key teeth, thereby facilitating the driving shaft to rotate through the connecting seat.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] This design realizes a stable connection and transmission between the main shaft and the connecting seat. When the electric push rod drives the connecting seat to rise and fall, the keyway of the connecting seat can accurately match the key teeth of the main shaft to form a stable transmission connection. In this way, the transmission shaft can be easily driven to rotate through the connecting seat, thereby realizing the angle adjustment of the turntable. This design not only improves the accuracy and stability of the transmission, but also makes the angle adjustment process of the turntable smoother and more controllable.

[0022] Furthermore, the connecting seat is driven to rise and fall by an electric push rod. When the turntable needs to accurately adjust the rotation angle or needs to be locked after rotation, the keyway of the connecting seat is driven by the electric push rod to engage with the key teeth of the transmission shaft.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] By driving the lifting and lowering of the connection seat with an electric push rod, the engagement and separation between the key slot of the connection seat and the key teeth of the transmission shaft can be flexibly controlled. When the angle of the turntable needs to be precisely adjusted or the turntable needs to be locked after rotation, the electric push rod drives the connection seat to rise, so that the key slot and the key teeth are tightly engaged, thereby ensuring the accuracy and stability of the transmission. This design not only improves the accuracy and reliability of the turntable angle adjustment, but also enables the turntable to remain locked when needed to prevent accidental rotation due to external forces.

[0025] Furthermore, when the turntable needs to be adjusted quickly, the connecting seat is driven by the electric push rod to locate the key teeth in the receiving groove, and then the main motor drives the driving wheel to drive the turntable to rotate through the synchronous belt.

[0026] The beneficial effects of adopting the above further scheme are:

[0027] When the turntable angle needs to be adjusted quickly, the electric push rod can be used to drive the connection seat down so that the key teeth are located in the receiving groove and separated from the key teeth of the transmission shaft. In this way, the turntable is no longer restricted by the connection seat and can be freely driven by the main motor to drive the driving wheel and the synchronous belt to rotate quickly. This design not only improves the flexibility of the turntable angle adjustment, but also enables the turntable to respond quickly and adjust to the position when needed, meeting the industrial robot's needs for rapid angle adjustment. At the same time, due to the separation of the key teeth and the keyway, it also avoids safety problems caused by transmission failure during rapid rotation.

[0028] The present invention provides an industrial robot connection base that is easy to adjust the angle. It has the following beneficial effects:

[0029] Through the combination of electric push rod and worm gear transmission system, the precise angle adjustment of the turntable (i.e. the installation part of the industrial robot) can be achieved. This design allows the user to easily change the direction of the industrial robot when needed, improving the flexibility and efficiency of work.

[0030] The ratchet teeth and the transmission wheel cooperate to realize the one-way rotation and locking function of the turntable. This means that when the turntable needs to keep its position unchanged, the locking effect of the ratchet teeth can prevent the turntable from rotating accidentally, which increases the stability and safety of the system.

[0031] The design structure of the entire connection base is compact, and the connection and transmission methods between the various components are simple and clear, which is easy for users to install, debug and operate. At the same time, the electric push rod drives the connection base to rise and fall, realizing precise control of the rotation of the transmission shaft and turntable, making the operation of the entire system more convenient.

[0032] This connection base is not only suitable for industrial robots that need to adjust the angle precisely, but also for scenarios where the turntable position needs to be adjusted quickly. By adjusting the position of the electric push rod, the working mode of the turntable (precise adjustment or quick adjustment) can be easily switched to meet different work needs.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figures 1 to 5 As shown, the embodiments provided by the present invention are:

[0044] Embodiment 1

[0045] An industrial robot connection base for easy angle adjustment includes a base plate 3, a shell 2 is installed on the base plate 3, a turntable 1 is rotatably installed on the shell 2, and the turntable 1 is used to install the industrial robot. An electric push rod 10 is installed on the base plate 3 inside the shell 2, and a worm wheel 11 is installed at the output end of the electric push rod 10. A worm 9 is installed on one side of the worm wheel 11 inside the shell 2, and a servo motor 4 is installed at one end of the worm 9. The servo motor 4 drives the worm 9 to rotate, and the electric push rod 10 drives the worm wheel 11 to mesh with or separate from the worm 9. A connecting seat 12 is provided on the worm wheel 11, and the connecting seat 12 drives the worm wheel 11 to rise and fall through the electric push rod 10. The seat 12 is provided with a receiving groove 1202, a key groove 1203 is provided above the receiving groove 1202, and a guide block 1201 is provided in the receiving groove 1202. The key teeth 1302 of the main shaft 1303 are guided into the key groove 1203 by the guide block 1201, and the receiving groove 1202 is connected with the key groove 1203 through the guide block 1201. The receiving groove 1202 and the key groove 1203 provided in the connecting seat 12, as well as the guide block 1201 provided in the receiving groove 1202, enable the key teeth 1302 of the main shaft 1303 to smoothly pass through the guide block 1201 and enter the key groove 1203, and realize a stable connection with the connecting seat 12. When the electric push rod 10 drives the turbine to rise and fall, the connecting seat 12 will also rise and fall accordingly, and then cooperate with the key teeth 1302 of the main shaft 1303 through the key groove 1203 to realize the rotation drive of the transmission shaft 13. This design not only improves the accuracy and stability of the transmission, but also makes the angle adjustment of the turntable 1 more flexible and controllable. At the same time, the design of the guide block 1201 also plays a role in guiding and positioning, ensuring that the key teeth 1302 can accurately enter the key slot 1203, avoiding the problem of transmission failure caused by improper installation. The top of the housing 2 is rotatably installed with a transmission shaft 13, and the bottom of the turntable 1 is provided with a transmission wheel 14. The transmission shaft 13 and the transmission wheel 14 are connected by ratchet teeth 1304. The inner side of the transmission wheel 14 is provided with a tooth groove 1401, and the tooth groove 1401 is engaged with the ratchet teeth 1304 of the fixed disk 1301, and then the transmission wheel 14 is driven to rotate unidirectionally through the transmission shaft 13, and the tooth groove 1401 provided on the inner side of the transmission wheel 14 is engaged with the ratchet teeth 1304 of the fixed disk 1301. This design realizes the unidirectional transmission between the transmission shaft 13 and the transmission wheel 14. When the transmission shaft 13 rotates, the ratchet teeth 1304 can smoothly fit into the tooth grooves 1401 of the transmission wheel 14, thereby driving the transmission wheel 14 and the turntable 1 to rotate. Due to the unidirectionality of the ratchet teeth 1304, when an external force acts in the reverse direction on the transmission wheel 14, the ratchet teeth 1304 will disengage from the tooth grooves 1401, preventing the transmission wheel 14 and the turntable 1 from rotating in the reverse direction.This one-way transmission design not only improves the efficiency and stability of the transmission, but also enables the turntable 1 to remain locked when needed to prevent accidental rotation due to external force. The ratchet teeth 1304 are elastically mounted on the fixed disk 1301 of the transmission shaft 13 through a torsion spring. The ratchet teeth 1304 are elastically mounted on the fixed disk 1301 of the transmission shaft 13 through a torsion spring. This design enables the ratchet teeth 1304 to deflect when subjected to external force, thereby achieving engagement and disengagement with the tooth groove 1401 of the transmission wheel 14. When the transmission shaft 13 rotates, the ratchet teeth 1304 can smoothly engage in the tooth groove 1401 of the transmission wheel 14, driving the transmission wheel 14 to rotate in one direction. When the external force acts in the opposite direction on the transmission wheel 14, the ratchet teeth 1304 will disengage from the tooth groove 1401 under the action of the torsion spring, thereby preventing the transmission wheel 14 from rotating in the opposite direction. This design not only improves the reliability and stability of the transmission, but also enables the turntable 1 to achieve the function of one-way rotation, meeting the specific requirements of the industrial robot for the angle adjustment direction.

[0046] Embodiment 2

[0047] In order to accurately adjust the rotation angle of the turntable 1 or lock the turntable 1 after rotation, for example, Figures 1 to 5As shown, the present invention also includes: a support seat 8 is installed at the top of the housing 2, the turntable 1 is supported and rotatably installed on the housing 2 by the support seat 8, the transmission shaft 13 and the connecting seat 12 are plugged into each other, and a main shaft 1303 is provided at the bottom of the fixed plate 1301, and a key tooth 1302 is provided on the main shaft 1303. When the connecting seat 12 drives the worm gear 11 to descend through the electric push rod 10, the main shaft 1303 cooperates with the key groove 1203 of the connecting seat 12 through the key tooth 1302, so as to facilitate the driving of the transmission shaft 13 through the connecting seat 12. This design realizes a stable connection and transmission between the main shaft 1303 and the connecting seat 12. When the electric push rod 10 drives the connecting seat 12 to rise and fall, the key groove 1203 of the connecting seat 12 can accurately cooperate with the key tooth 1302 of the main shaft 1303 to form a stable transmission connection. In this way, the transmission shaft 13 can be easily driven to rotate through the connecting seat 12, thereby realizing the angle adjustment of the turntable 1. This design not only improves the accuracy and stability of the transmission, but also makes the angle adjustment process of the turntable 1 smoother and more controllable. When the turntable 1 needs to be adjusted quickly, the electric push rod 10 drives the worm wheel 11 to drive the connecting seat 12, so that the key tooth 1302 is located in the receiving groove 1202, so that the key groove 1203 is separated from the key tooth 1302 of the transmission shaft 13, and then the main motor 5 drives the driving wheel 7, so that the driving wheel 7 drives the turntable 1 to rotate through the synchronous belt 6. In the case of needing to quickly adjust the angle of the turntable 1, the electric push rod 10 can drive the connecting seat 12 to descend, so that the key tooth 1302 is located in the receiving groove 1202 and is separated from the key tooth 1302 of the transmission shaft 13. In this way, the turntable 1 is no longer restricted by the connecting seat 12, and can be freely driven by the main motor 5 to drive the driving wheel 7 and the synchronous belt 6 to rotate quickly. This design not only improves the flexibility of the angle adjustment of the turntable 1, but also enables the turntable 1 to respond quickly and adjust to the position when needed, meeting the needs of industrial robots for rapid angle adjustment. At the same time, due to the separation of the key teeth 1302 and the key slots 1203, the safety problem caused by transmission failure during the rapid rotation process is also avoided. When the turntable 1 needs to accurately adjust the rotation angle or the turntable 1 needs to be locked after rotation, the electric push rod 10 drives the worm wheel 11 to drive the connection seat 12 to rise, so that the key slot 1203 of the connection seat 12 is engaged with the key teeth 1302 of the transmission shaft 13. The electric push rod 10 drives the lifting and lowering of the connection seat 12, and the engagement and separation between the key slot 1203 of the connection seat 12 and the key teeth 1302 of the transmission shaft 13 can be flexibly controlled. When the angle of the turntable 1 needs to be accurately adjusted or the turntable 1 needs to be locked after rotation, the electric push rod 10 drives the connection seat 12 to rise, so that the key slot 1203 is tightly engaged with the key teeth 1302, thereby ensuring the accuracy and stability of the transmission. This design not only improves the accuracy and reliability of the angle adjustment of the turntable 1, but also enables the turntable 1 to remain locked when needed to prevent accidental rotation due to external force.

[0048] Working principle:

[0049] When the servo motor drives the worm to rotate, the worm and the worm wheel mesh with each other. Due to the characteristics of the worm gear transmission (large transmission ratio, smooth transmission, and self-locking), the worm wheel can be accurately rotated and locked. The worm gear transmission also enables the device to achieve self-locking when necessary, preventing the turntable from rotating on its own when no external force is applied.

[0050] The electric push rod drives the push rod to move up and down through the motor inside it. During the lifting process, the output end of the electric push rod drives the worm wheel to rise or fall. When the worm wheel descends, it can fully mesh with the worm to achieve precise transmission; when the worm wheel rises, it can separate from the worm, and the turntable can be quickly rotated by other means (such as the main motor drives the driving wheel and the synchronous belt).

[0051] The transmission shaft and the transmission wheel are connected by ratchet teeth. The ratchet teeth have the characteristic of one-way transmission, that is, they can only transmit power in one direction. When the turbine drives the transmission shaft to rotate through the connecting seat, due to the action of the ratchet teeth, the transmission wheel will rotate in one direction and drive the turntable to rotate. When the turntable needs to be locked, just lift the turbine through the electric push rod and make the keyway of the connecting seat mesh with the key teeth of the transmission shaft. At this time, due to the self-locking property of the worm gear and the one-way transmission characteristic of the ratchet teeth, the turntable is locked at a specific angle.

[0052] When the turntable needs to be adjusted quickly (such as changing the angle of the turntable within a large range), it can be achieved by driving the driving wheel and the synchronous belt through the main motor. At this time, the turbine and the worm are separated to avoid unnecessary friction and wear. When the turntable needs to be accurately adjusted or locked (such as fine-tuning the angle of the turntable within a small range or locking it at a specific position), the electric push rod can be used to drive the turbine to descend and engage with the worm. At this time, due to the accuracy and self-locking property of the worm gear transmission, it can ensure that the turntable can accurately stay at the required angle and be locked.

[0053] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
