Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of robots, in particular to a robot clamping device. BACKGROUND

[0002] At present, in intelligent manufacturing production, robots begin to gradually replace manual work to participate in industrial production. The transfer of workpieces in industrial production is very cumbersome, so more and more workpiece clamping and transfer work is replaced by robot clamping devices. The types and shapes of workpieces are various, and the single workpiece clamping mode of the robot in the prior art cannot meet the demand. For example, cylindrical and block-shaped workpieces need different robots to clamp and transfer, which will cause the number of single production station robots to increase, and the robots are easy to interfere with each other, affecting the efficiency of industrial production. SUMMARY

[0003] The technical problem to be solved by the present application is to overcome the defects of the prior art, provide a robot clamping device which can stably clamp cylindrical or block-shaped workpieces, quickly transfer the workpieces to the required position, reduce the number of single production station robots, avoid mutual interference of multiple robots, and adjust the buffering force during clamping to avoid clamping damage to the workpiece, thereby improving the efficiency of industrial production and effectively solving the problems in the background art.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a robot clamping device, comprising an operation transfer mechanism, a steering mechanism is installed on the operation transfer mechanism, the bottom of the steering mechanism is fixedly connected with the top end of a lifting electric telescopic rod, and further comprising:

[0005] A clamping orientation control mechanism comprises an orientation changing assembly and a horizontal locking assembly, the orientation changing assembly is installed at the bottom end of the lifting electric telescopic rod, and the horizontal locking assembly is installed on the orientation changing assembly;

[0006] A clamping control mechanism comprises a support frame and a clamping electric telescopic rod, the bottom of the orientation changing assembly is connected with the top of the support frame, a horizontal recess is formed in the bottom of the support frame, two clamping control frames are respectively horizontally slidably connected in the horizontal recess on the left and right sides, the side of each clamping control frame close to the other clamping control frame is provided with a slope, two dovetail sliding grooves are respectively formed in the two slopes, the clamping electric telescopic rod is installed on the top of the support frame, an isosceles trapezoidal control block is connected to the bottom end of the clamping electric telescopic rod, two dovetail sliding strips are respectively arranged on the left and right sides of the isosceles trapezoidal control block, and the two dovetail sliding strips are respectively slidably connected with the two dovetail sliding grooves;

[0007] A clamping buffer mechanism is installed at the bottom of the clamping control frame, and a workpiece clamping mechanism is installed at the bottom of the clamping buffer mechanism.

[0008] Further, the orientation changing assembly comprises a movable seat, a swing rod, a connecting frame, an orientation motor and an orientation shaft, the bottom end of the lifting electric telescopic rod is fixedly connected to the top of the movable seat, the bottom of the movable seat is rotatably connected with a transverse orientation shaft, one end of the orientation shaft is fixedly connected with the orientation motor, the orientation motor is installed on the side of the movable seat, the middle part of the orientation shaft is fixedly connected with the top of the swing rod, the bottom of the swing rod is fixedly connected with the connecting frame, and the bottom of the connecting frame is fixedly connected with the top of the supporting frame. The orientation motor drives the orientation shaft to rotate, so that the supporting frame can be driven to rotate through the swing rod and the connecting frame. In specific work, if the orientation motor drives the orientation shaft to rotate counterclockwise by ninety degrees, the supporting frame can be in a horizontal state, so that the two workpiece clamping mechanisms are in a horizontal state, so that the two workpiece clamping mechanisms can clamp the workpiece from the side of the workpiece to be clamped. If the orientation motor remains stationary, the two workpiece clamping mechanisms can clamp the workpiece from the top to the bottom of the workpiece to be clamped.

[0009] Further, the horizontal locking assembly comprises a bent frame, a locking electric telescopic rod, a locking pin shaft, a locking limiting hole, a locking seat block and a locking pin hole, the bottom of the swing rod is provided with a transverse locking limiting hole, one end of the locking electric telescopic rod is fixedly connected to the top of the connecting frame through the bent frame, the other end of the locking electric telescopic rod is fixedly connected to one end of the locking pin shaft, the locking pin shaft is slidably connected with the locking limiting hole, and the bottom side of the movable seat is fixedly connected with the locking seat block. When the orientation motor drives the orientation shaft to rotate counterclockwise by ninety degrees to make the supporting frame in a horizontal state, the locking limiting hole and the locking pin hole on the locking seat block are correspondingly arranged, at this time, the locking electric telescopic rod is elongated, the end of the locking pin shaft is inserted into the locking pin hole, the relative position of the swing rod and the movable seat is locked, and the weight of the clamping control mechanism, the clamping buffer mechanism, the workpiece clamping mechanism and the clamped workpiece will not have a large pressure on the orientation motor, so as to protect the orientation motor and avoid damaging the orientation motor due to excessive force. If the orientation motor needs to work reversely to make the two workpiece clamping mechanisms clamp the workpiece downward again, the locking electric telescopic rod is shortened, the locking pin shaft is separated from the locking pin hole, and then the orientation motor can drive the orientation shaft, the connecting frame and the supporting frame to rotate reversely to reset.

[0010] Further, the clamping buffer mechanism comprises a buffer seat plate, an end plate, a horizontal guide column, a buffer spring, a buffer slider, a clamping seat plate and a buffer force adjustment assembly. The bottom surface of each clamping control frame is respectively provided with a buffer seat plate. The bottom of the buffer seat plate is respectively fixedly connected with two end plates. Two horizontal guide columns are fixedly connected between the two end plates. The two horizontal guide columns are respectively slidably connected with two guide holes on the buffer slider. The bottom of the buffer slider is fixedly connected with a clamping seat plate. Each horizontal guide column is sleeved with a buffer spring away from one end of the isosceles trapezoidal control block. The buffer force adjustment assembly is installed on the end plate away from the isosceles trapezoidal control block at the bottom of the buffer seat plate. When clamping the workpiece, a certain buffer force is generally required to avoid the workpiece clamping mechanism from damaging the workpiece due to excessive clamping force. The buffer seat plate and the end plate are used to install the horizontal guide column. The horizontal guide column guides the movement direction of the buffer slider. When the two workpiece clamping mechanisms clamp the workpiece, the buffer slider slides along the horizontal guide column to compress the buffer spring. The buffer spring can buffer the clamping force of the workpiece clamping mechanism. The buffer force adjustment assembly can compress the buffer spring to a certain extent in advance to increase the pressure of the workpiece clamping mechanism when clamping the workpiece, increase the friction between the workpiece clamping mechanism and the workpiece, and avoid the workpiece from being separated from the workpiece clamping mechanism due to the small pressure of the buffer spring when the two clamping control frames are close to each other.

[0011] Further, the buffer force adjustment assembly comprises a control motor, a lead screw, a lead screw nut, a buffer force control plate, a control motor, a lead screw, a lead screw nut and a buffer force control plate. The control motor is fixedly connected with one end of the output shaft of the control motor. The lead screw is parallel to the horizontal guide column. The two guide holes on the buffer force control plate are slidably connected with two horizontal guide columns away from one end of the isosceles trapezoidal control block. The buffer spring is located between the buffer slider and the buffer force control plate. The lead screw nut is installed on the buffer force control plate and is connected with the lead screw. When the control motor works, the lead screw rotates clockwise. The threads of the lead screw and the lead screw nut drive the buffer force control plate to compress the buffer spring, so that the buffer spring can exert a larger elastic force on the buffer slider, which is beneficial to the clamping of the workpiece by the two workpiece clamping mechanisms. At the same time, the compressed buffer spring can still play a buffering role in clamping the workpiece. When the control motor works, the lead screw rotates counterclockwise. The threads of the lead screw and the lead screw nut drive the buffer force control plate to release the buffer spring. The elastic force of the buffer spring on the buffer slider becomes smaller. When the two workpiece clamping mechanisms clamp the workpiece, the pressure of the workpiece clamping mechanism on the workpiece is smaller. Although there is a risk of falling when encountering heavy workpieces, the workpiece can be better protected when facing fragile workpieces to avoid damage caused by excessive clamping force.

[0012] Further, the workpiece clamping mechanism comprises horizontal swallow-tail guide bars one, horizontal sliding seats one, U-shaped plane clamping frames, horizontal swallow-tail guide bars two, horizontal sliding seats two, arc clamping plates, clamping end plates, reverse transmission assemblies and clamping switching power assemblies, the bottom of each clamping seat plate is fixedly connected with two horizontal swallow-tail guide bars one on the front and back sides, respectively, the top of each U-shaped plane clamping frame is connected with two horizontal sliding seats one at both ends, respectively, the two horizontal sliding seats one are slidingly connected with the two horizontal swallow-tail guide bars one, respectively, the bottom center of each clamping seat plate is fixedly connected with a horizontal swallow-tail guide bar two, the top of the arc clamping plate is connected with a horizontal sliding seat two, the horizontal sliding seat two is slidingly connected with the horizontal swallow-tail guide bar two, the bottom end of the arc clamping plate is connected with a clamping end plate, the arc clamping plate is connected with a corresponding U-shaped plane clamping frame through a reverse transmission assembly, and the U-shaped plane clamping frame is connected with a clamping switching power assembly.

[0013] Further, the reverse transmission assembly comprises a rack one, a rack two, a switching shaft and a switching transmission gear, the U-shaped plane clamping frame is fixedly connected with the transverse rack one away from one side of the isosceles trapezoidal control block, the circular arc clamping plate is fixedly connected with the transverse rack two away from one side of the isosceles trapezoidal control block, the clamping seat plate is fixedly connected with the switching shaft at the bottom away from one end of the isosceles trapezoidal control block, the switching shaft is rotatably connected with the switching transmission gear at the end, the switching transmission gear is located between the rack one and the rack two, and the switching transmission gear is respectively meshed with the corresponding rack one and the rack two. The rack one, the rack two and the switching transmission gear cooperate, the rack one is driven to move right by the transmission gear and the rack two when the U-shaped plane clamping frame moves left, and vice versa, the rack one is also driven to move left by the transmission gear and the rack two when the U-shaped plane clamping frame moves right, so that the U-shaped plane clamping frame and the circular arc clamping plate realize reverse movement on the front side of the clamping seat plate.

[0014] Further, the clamping switching power assembly comprises a telescopic rod mounting bracket, a switching electric telescopic rod and a bent seat, the U-shaped plane clamping frame is fixedly connected with the bent seat, the bent seat is fixedly connected with one end of the transverse switching electric telescopic rod, the clamping seat plate is fixedly connected with the telescopic rod mounting bracket away from one end of the isosceles trapezoidal control block, and the other end of the telescopic rod mounting bracket is fixedly connected with the switching electric telescopic rod.

[0015] Further, the transverse clamping alignment mechanism comprises an alignment plate and an alignment push-pull assembly, the lower side of the isosceles trapezoidal control block is provided with the alignment plate, and the alignment plate is connected with the isosceles trapezoidal control block through the alignment push-pull assembly. When the two workpiece clamping mechanisms clamp a plurality of overlapped workpieces, the overlapped workpieces may not be aligned, and may fall off after clamping. At this time, the alignment push-pull assembly can push the alignment plate, so that the alignment plate pushes the overlapped workpieces on one side, and then the alignment push-pull assembly makes the alignment plate re-enter the isosceles trapezoidal control block, so as to avoid the interference of the alignment plate with the two buffer seat plates moving close to each other.

[0016] Further, the alignment push-pull assembly comprises alignment guide columns, an alignment connecting rod, a blind hole and an alignment electric telescopic rod, two alignment vertical holes are formed in the isosceles trapezoidal control block, two alignment guide columns are slidably connected in the two alignment vertical holes respectively, the bottoms of the two alignment guide columns are fixedly connected to the top of the alignment plate, a blind hole is formed in the top of the isosceles trapezoidal control block, a vertical alignment electric telescopic rod is installed in the blind hole, one end of the alignment connecting rod is fixedly connected to the top of the alignment electric telescopic rod, and the other end of the alignment connecting rod is fixedly connected to the top of one of the alignment guide columns.

[0017] Compared with the prior art, the robot clamping device has the following advantages:

[0018] 1. The operation transfer mechanism is used to drive the workpiece clamping mechanism to move in a range, the steering mechanism is used to change the orientation of the workpiece clamping mechanism, the lifting electric telescopic rod can drive the workpiece clamping mechanism to move up and down, and the orientation changing assembly is used to drive the workpiece clamping mechanism to be vertically or horizontally arranged, so that the workpiece clamping mechanism clamps the workpiece downward or horizontally. When the workpiece clamping mechanism clamps the workpiece in the horizontal orientation, if the workpiece is heavy, the orientation changing assembly will be subjected to a large pressure and be easily damaged. Therefore, the horizontal locking assembly is arranged to lock the workpiece clamping mechanism in the horizontal orientation, so as to reduce the pressure on the orientation changing assembly.

Then, the operation transfer mechanism, the steering mechanism, the lifting electric telescopic rod and the orientation changing assembly drive the two workpiece clamping mechanisms to move close to the workpiece to be clamped. The clamping electric telescopic rod is shortened to drive the isosceles trapezoidal control block to move close to the orientation changing assembly. The isosceles trapezoidal control block drives the two clamping control frames to move close to each other in the horizontal groove through the cooperation of the dovetail sliding groove and the dovetail sliding strip, so as to drive the two workpiece clamping mechanisms to move close to each other through the two clamping buffer mechanisms. The two workpiece clamping mechanisms clamp the workpiece. The clamping buffer mechanism can avoid damaging the workpiece due to too large clamping force of the two workpiece clamping mechanisms.

[0020] 3、The robot clamping device can stably clamp cylindrical or block-shaped workpieces, and can quickly transfer the workpieces to the required position, can reduce the number of robots of a single production station, avoid mutual interference of multiple robots, and can adjust the buffering force during clamping to avoid clamping damage to the workpiece, and is beneficial to improve the efficiency of industrial production.
