Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are in simplified form and are not to be construed as precise ratios, which are merely intended to facilitate and clarify the explanation of the embodiments of the present invention.
It should be noted that all the directional indicators (such as up, down, left, right, front, back, 8230; \8230;) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the attached drawings), and if the specific posture is changed, the directional indicator is changed accordingly.
Referring to fig. 1, the core of the present invention is to provide a flexible fixture platform for robot, which comprises a fixture plate 1, a mounting plate 2, at least two guide rods and at least two elastic members.
The clamp plate 1 is used for installing a clamp, and the clamp comprises a plurality of positioning blocks, supporting blocks and the like and is used for clamping workpieces. The mounting plate 2 is disposed below the clamp plate 1, and the guide rods penetrate through and are slidably connected to the clamp plate 1, wherein two guide rods are disposed in the embodiment, but other numbers are also possible in other embodiments, and the mounting plate is not limited here and can be flexibly adjusted according to actual conditions.
The lower extreme and the mounting panel 2 of guide bar link firmly, and the upper end of guide bar is equipped with spacing portion 4, and spacing portion 4 is located the top of anchor clamps board 1 for restriction anchor clamps board 1 leaves the guide bar, and the adjacent surface of spacing portion 4 and anchor clamps board 1 adjacent end is the inclined plane.
An elastic piece is sleeved on each guide rod and is positioned between the clamp plate 1 and the mounting plate 2. The resilient member in this embodiment is a spring 6.
When the robot gripper grips a workpiece on a clamp arranged on the clamp plate 1, acting force on the workpiece and the clamp is transmitted to the elastic piece through the clamp plate 1 to be buffered, so that mechanical damage caused by hard contact impact between the workpiece and the clamp is avoided.
Specifically, the guide rod is a countersunk head bolt 3, the limiting part 4 is the head of the countersunk head bolt 3, a countersunk head slide hole corresponding to the countersunk head bolt 3 is arranged on the clamp plate 1, and the countersunk head bolt 3 is arranged in the countersunk head slide hole. The inclined plane of the lower end of the head of the countersunk head bolt 3 and the inclined plane of the upper end of the countersunk head slide hole form the inclined plane of the adjacent end of the limiting part 4 and the clamp plate 1. When the clamp plate 1 is upwards moved and reset through the elastic force of the spring 6, the countersunk head bolt 3 and the countersunk head slide hole are impacted, so that the lower end inclined plane of the head of the countersunk head bolt 3 is in impact contact with the upper end inclined plane of the countersunk head slide hole, the contact surface increases the impact area for the inclined plane, the impact force is dispersed, the abrasion of parts caused by the movement of the clamp plate 1 on the countersunk head bolt 3 is avoided, and the service life of the countersunk head bolt 3 and the clamp plate 1 is prolonged. And the countersunk head bolt 3 and the countersunk head slide hole of the embodiment are both of inclined plane type, but not other column type and the like.
In practical use, if the contact surface between the limiting part 4 and the clamp plate 1 is a plane, that is, the guide rod is a flat-head bolt, the clamp plate 1 is easily bumped, and the clamp plate 1 is inclined, so that the grabbing precision of the robot gripper is affected.
Preferably, a rubber paste or other flexible material can be arranged on the inclined plane at the lower end of the head of the countersunk head bolt 3 and the inclined plane at the upper end of the countersunk head slide hole, so that the impact is further reduced.
The mounting plate 2 is provided with a nut 5 corresponding to the countersunk head bolt 3 on the end surface close to the clamp plate 1, and the nut 5 is welded and connected to the clamp plate 1. The lower end of the countersunk head bolt 3 is penetrated and screwed in the nut 5 and then is penetrated and slidably connected with the mounting plate 2. The nut 5 is arranged to facilitate the mounting and dismounting of the countersunk head bolt 3, the lower end of the countersunk head bolt 3 is penetrated and connected to the mounting plate 2 in a sliding mode, the mounting of the countersunk head bolt 3 is more stable, the supporting point is equivalently increased, and after the robot gripper applies acting force to the clamp plate 1, the clamp plate 1 is not prone to shaking, so that the grabbing precision is improved.
Furthermore, a dust cover 7 is arranged above the sliding connection position of each countersunk head bolt 3 and the countersunk head slide hole, and the dust cover 7 is fixedly connected to the upper end face of the clamp plate 1 and is positioned above the limiting part 4. When the clamp plate 1 moves downwards, the head of the countersunk head bolt 3 can move in the dust cover 7. Can prevent effectively through dust cover 7 that the dust from getting into between countersunk head bolt 3 and the countersunk head slide hole, prevent the jamming of anchor clamps board 1 and countersunk head bolt 3 relative slip, make the utility model discloses adaptable more abominable complicated operating mode.
The working process of the present invention is further explained as follows:
when the robot gripper grabs the workpiece, the gripper executes downward force to grab the workpiece, the workpiece is subjected to downward acting force and is transmitted to the clamp, the clamp transmits the force to the clamp plate 1, the clamp plate 1 overcomes the elastic force of the spring 6 and slides downwards, and the spring 6 is compressed.
When the elastic force of the spring 6 is larger than the force applied to the workpiece, the clamp and the clamp plate 1 by the gripper, or the gripper grabs the workpiece to move upwards, the clamp plate 1 moves upwards to reset through the elastic force of the spring 6, and the clamp plate 1 is limited through the matching of the countersunk head bolt 3 and the countersunk head slide hole during resetting.
The utility model discloses a flexible anchor clamps platform for robot passes through the effort of 6 buffering robot tongs of spring, has avoided the hard contact between work piece and the anchor clamps to strike the mechanical damage who causes, increases each spare part life, has avoided unnecessary shut down problem, increases production efficiency. And after the impact between the workpiece and the clamp is reduced, the workpiece can be prevented from shifting due to the impact, the workpiece grabbing precision of the robot gripper is guaranteed, and the grabbing consistency is guaranteed.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, the changes are still within the scope of the present invention if they fall within the scope of the claims and their equivalents.
