Description

Technical Field

[0001] This utility model belongs to the field of electric gripper technology, specifically relating to an electric gripper suitable for high and low temperature vacuum environments. Background Technology

[0002] Electric grippers have been widely used in automated equipment, robots, and medical automated equipment. They can open and close the gripper fingers through motors and corresponding transmission mechanisms. However, high and low temperature environments and vacuum environments have a strong impact on mechanical control. Traditional electric grippers cannot operate effectively in extremely high, low, and vacuum environments. Some test scenarios require testing under extreme conditions. When traditional electric grippers operate in vacuum and high and low temperature environments, their motion accuracy is affected by the environment and does not meet the test requirements. Therefore, we propose an electric gripper that can be used in high and low temperature vacuum environments. Utility Model Content

[0006] As a preferred technical solution of this utility model, the gripper assembly includes a mounting plate, which is bolted to the bottom of the fixed base. The surface of the mounting plate has two through slots, and each slot has an adjusting claw. The bottom of the mounting plate has a sliding groove, in which two clamping blocks are slidably installed. The top of each clamping block has a movable groove, and each adjusting claw is connected to a corresponding clamping block. The adjusting claw is rotatably installed in the slot.

[0007] As a preferred technical solution of this utility model, the adjusting claw includes a rotating connecting part, a crossing part, and a movable connecting part. The rotating connecting part has a connecting hole. The bottom end of the fixed base has two corresponding first mounting holes on both sides.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-8This utility model provides the following technical solution: an electric gripper suitable for high and low temperature vacuum environments, including a fixed base 1 and a drive motor 2. The drive motor 2 is a high and low temperature vacuum motor. The fixed base 1 is made of stainless steel. The top of the fixed base 1 is provided with a mounting groove 3, and the bottom of the fixed base 1 is provided with a strip-shaped groove 4. The bottom of the mounting groove 3 is provided with an opening 5 that passes through the strip-shaped groove 4. The bottom of the mounting groove 3 is provided with insertion holes 6 on both sides of the opening 5. A lifting component 7 is installed in the mounting groove 3. One end of the lifting component 7 passes through the opening 5 and extends into the strip-shaped groove 4 and is connected to the gripper component 8. The drive motor 2 is fixedly installed on the top of the fixed base 1 by bolts and is connected to the lifting component 7.

[0024] In this embodiment, the lifting assembly 7 includes a lead screw nut 71 disposed in the mounting groove 3, a lifting lead screw 72 installed in the middle of the lead screw nut 71, a connecting plate 73 installed at the bottom end of the lead screw nut 71 by bolts, a lifting shaft 74 disposed at the bottom end of the connecting plate 73, first guide holes 75 opened on both sides of the connecting plate 73, and second guide holes opened on both sides of the lead screw nut 71, a guide rod 76 inserted into the first guide hole 75 and the second guide hole, the top end of the guide rod 76 connected to the cover plate 77, the bottom end of the guide rod 76 inserted into the insertion hole 6, a through hole opened in the middle of the cover plate 77, the output shaft of the drive motor 2 passing through the through hole and connected to one end of the lifting lead screw 72, a connecting groove 78 opened at the bottom end of the lifting shaft 74, the lifting shaft 74 passing through the opening 5 and extending into the strip-shaped slot 4 and connected to the gripper assembly 8, the lead screw nut 71 is made of ceramic, and the lifting lead screw 72 is made of stainless steel.

[0025] Specifically, the drive motor 2 drives the lifting screw 72 to rotate, which in turn causes the screw nut 71 to rise and fall in the mounting groove 3 along the direction of the lifting screw 72. This, in turn, causes the connecting plate 73 to drive the lifting shaft 74 to rise and fall. When the lifting shaft 74 rises and falls, it drives the gripper assembly 8 to close or open. The first guide rod 76 can improve the stability of the screw nut 71 during the rise and fall. Moreover, the screw nut 71 is made of ceramic, the lifting screw 72 is made of stainless steel, the drive motor 2 is a high and low temperature vacuum motor, and the fixed base 1 is made of stainless steel. Therefore, the electric gripper will not be affected by extreme environmental factors such as high and low temperatures and vacuum during use, thereby improving the operating accuracy of the electric gripper during use.

[0026] In this embodiment, the gripper assembly 8 includes a mounting plate 81, which is bolted to the bottom of the fixed base 1. The surface of the mounting plate 81 has two through slots 82, and each slot 82 is provided with an adjusting claw 83. The bottom of the mounting plate 81 has a sliding groove 84, in which two clamping blocks 85 are slidably installed. The top of the clamping blocks 85 has a movable groove 86. Each adjusting claw 83 is connected to the corresponding clamping block 85, and the adjusting claw 83 is rotatably installed in the slot 4.

[0027] Specifically, the lifting shaft 74 drives the adjusting claw 83 to rotate within the strip slot 4. When the adjusting claw 83 rotates, it drives the corresponding clamping block 85 to move towards or away from each other within the sliding groove 84, thereby opening or closing the electric clamping claw.

[0028] In this embodiment, the adjusting claw 83 includes a rotating connecting part 831, a crossing part 832, and a movable connecting part 833. The rotating connecting part 831 has a connecting hole 834. The bottom end of the fixed base 1 has two corresponding first mounting holes 9 on both sides. The adjusting claw 83 is rotatably disposed in the strip slot 4 through the first connecting pin inserted into the corresponding first mounting hole 9 via the connecting hole 834. The end of the crossing part 832 has a crossing groove 835. The crossing parts 832 of the two adjusting claws 83 are both disposed in the connecting groove 78, and a crossing hole 836 is formed between the two crossing grooves 835. The crossing part 832 and the lifting shaft 74 are movably connected through the second connecting pin inserted between the crossing hole 836 and the connecting groove 78. The end of the movable connecting part 833 has a movable protrusion 837, which is movably installed in the movable groove 86.

[0029] Specifically, the first mounting hole 9 and the connecting hole 834 allow the adjusting claw 83 to rotate within the strip slot 4. Since the intersection 832 of the two adjusting claws 83 forms the intersection hole 836, when the lifting shaft 74 is raised or lowered, the second connecting pin will cause the two adjusting claws 83 to rotate within the strip slot 4. When the adjusting claws 83 rotate, the movable protrusion 837 at the end of the movable connecting part 833 will move within the movable groove 86. Since the movable protrusion 837 is movably installed within the movable groove 86, the movable protrusion 837 will cause the clamping block 85 to move along the slide groove 84 without motion interference.

[0030] In this embodiment, the top of the mounting groove 3 is provided with four corner grooves 10, and the four corners of the cover plate 77 are respectively placed in the corresponding corner grooves 10 and the drive motor 2 is pressed against the top of the cover plate 77.

[0031] Specifically, since the drive motor 2 is connected to the fixed base 1 by bolts and the drive motor 2 is pressed against the cover plate 77, this method makes it easy to remove the lifting assembly 7 from the mounting slot 3 after removing the drive motor 2, thus making it easier to inspect and maintain the electric gripper.

[0032] In this embodiment, the dimensions of the lead screw nut 71 match the dimensions of the mounting groove 3.

[0033] Specifically, this method enables the lead screw nut 71 to move stably up and down within the mounting slot 3.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
