Description

Technical Field

[0001] The utility model belongs to the field of automatic clamping, and more specifically, it relates to a part torque clamping device. Background Technique

[0002] Automatic clamping refers to the use of robots or automated equipment to grasp and place objects in industrial or manufacturing processes. This technology is widely used in production lines, warehousing, logistics and other fields, aiming to improve efficiency, reduce labor costs and reduce human errors.

[0003] At present, in the process of handling plastic shells, automatic clamping is usually carried out by using pneumatic grippers. Although pneumatic grippers can open and close quickly and are suitable for production lines that require high-speed operation, pneumatic grippers are prone to cause deformation and damage to plastic shells during the clamping process. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a part torque clamping device, which has the advantages of controlling the clamping force of parts and avoiding product deformation and damage.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A part torque clamping device includes a support frame, a linear movement component located on the support frame, and a lifting component located on the linear movement component. An installation plate one is installed at the output end of the lifting component, and a clamping component for clamping a plastic shell is installed on the installation plate one. The clamping component includes: an electric gripper fixedly installed on the installation plate one, a chuck fixed to the output end of the electric gripper through a locking member, a movable part installed on the chuck and capable of automatic reset, and an elastic part fixed between the chuck and the movable part;

[0007] It also includes a laser displacement sensor electrically connected to the electric gripper through a controller. The laser displacement sensor is located on the movable part and is arranged facing the chuck.

[0008] The advantages of this solution are at least as follows: When handling a plastic shell, start the lifting component and the clamping component to pick up the plastic shell, and move the plastic shell to the required position through the linear movement component. During the clamping process, the movable part first contacts the outer wall of the plastic shell. During the clamping process of the electric gripper, the movable part moves on the chuck and compresses the elastic part. The distance that the movable part moves on the chuck is measured by the laser displacement sensor, and the compression amount of the spring is indirectly judged, so as to judge the elastic force value of the spring, and then judge the clamping force of the electric gripper on the product. When the clamping force reaches the preset value range, it is then fed back to the electric gripper to ensure that the electric gripper does not clamp the plastic shell excessively, avoiding deformation and damage of the plastic shell.

[0009] The present utility model is further configured such that: the movable part includes a guide rod slidably mounted on the chuck, a clamping plate located at the end of the guide rod, and a second mounting plate, and the laser displacement sensor is located on the second mounting plate.

[0010] The advantages of this solution are at least as follows: the clamping plate is used to clamp the plastic housing, and the guide rod plays a guiding role for the clamping plate to ensure that the moving path of the clamping plate is more stable, thereby ensuring the measurement accuracy of the laser displacement sensor for the elastic part.

[0011] The present utility model is further configured such that: it further includes a plurality of reset components fixed between the chuck and the clamping plate, and the reset components are composed of a plurality of reset springs.

[0012] The advantages of this solution are at least as follows: after the plastic housing is put down, it will automatically rebound under the action of the reset spring and the elastic part, and the clamping plate is reset to the position before clamping.

[0013] The present utility model is further configured such that: a silica gel sheet is pasted on the surface of the clamping plate in contact with the product, and anti-slip lines are provided on the silica gel sheet.

[0014] The advantages of this solution are at least as follows: the silica gel sheet plays a certain buffering role when clamping the plastic housing, and the anti-slip lines increase the friction between the silica gel sheet and the plastic housing to prevent it from falling off during the clamping process.

[0015] The present utility model is further configured such that: a stabilizing column is provided on the clamping plate and facing the chuck, the stabilizing column is located inside the reset spring and the elastic part and inserted into the chuck and is slidably connected to the chuck.

[0016] The advantages of this solution are at least as follows: the stabilizing column can avoid the problem that the reset spring and the elastic part fall off due to the fracture of the end part, and in addition, it can ensure the stability of the linear movement of the reset spring and the elastic part.

[0017] The present utility model is further configured such that: a limiting block is provided at the end of the stabilizing column away from the clamping plate.

[0018] The advantages of this solution are at least as follows: when the end parts of the reset spring and the elastic part are fractured, the limiting block can avoid the phenomenon that the stabilizing column moves excessively and falls off from the chuck.

[0019] In summary, the present utility model has at least the following advantages:

[0020] 1. By setting an activatable part that can be automatically reset, an elastic part fixed between the chuck and the activatable part, and a laser displacement sensor electrically connected to the electric gripper through a controller, when handling a plastic housing, the lifting component and the clamping component are activated to clamp the plastic housing, and the plastic housing is moved to the required position through the linear movement component. During the clamping process, the activatable part first contacts the outer wall of the plastic housing. During the clamping process of the electric gripper, the activatable part moves on the chuck and compresses the elastic part. The distance that the activatable part moves on the chuck is measured by the laser displacement sensor, and the compression amount of the spring is indirectly judged, thereby judging the elastic force value of the spring, and then judging the clamping force of the electric gripper on the product. When the clamping force reaches the preset value range, it is then fed back to the electric gripper to ensure that the electric gripper does not clamp the plastic housing excessively, avoiding deformation and damage of the plastic housing;

[0021] 2. By setting a clamping plate and a guide rod, the clamping plate is used to clamp the plastic housing, and the guide rod plays a guiding role for the clamping plate to ensure that the moving path of the clamping plate is more stable, thereby ensuring the measurement accuracy of the laser displacement sensor for the elastic part;

[0022] 3. By setting a reset component, after the plastic housing is put down, it will automatically rebound under the action of the reset spring and the elastic part, and the clamping plate is reset to the position before clamping. By setting a stabilizing column, the stabilizing column can avoid the problem that the reset spring and the elastic part fall off due to fracture at the end, and can also ensure the stability of the linear movement of the reset spring and the elastic part.

[0028] A part torque clamping device, as Figure 1As shown in the figure, it includes a support frame 1, a linear movement component 2 located on the support frame 1, and a lifting component 3 located on the linear movement component 2. In some embodiments, the linear movement component 2 and the lifting component 3 can be composed of a motor, a lead screw key-connected to the motor, and a slider threadedly connected to the lead screw and only capable of linear movement in cooperation with a guide rail. In other embodiments, the linear movement component 2 can also be a cylinder. An installation plate 4 is installed at the output end of the lifting component 3, and a clamping component 5 for clamping the plastic housing 10 is installed on the installation plate 4.

[0029] As Figure 2 shown in the figure, the clamping component 5 includes: an electric gripper 501 fixedly installed on the installation plate 4, a chuck 502 fixed to the output end of the electric gripper 501 through a locking member. The locking member is preferably a bolt (not shown in the figure), a movable part 503 installed on the chuck 502 and capable of automatic reset, and an elastic part 504 fixed between the chuck 502 and the movable part 503. The elastic part 504 is preferably a spring; the clamping component 5 also includes a laser displacement sensor 505 electrically connected to the electric gripper 501 through a controller (not shown in the figure). The laser displacement sensor 505 is located on the movable part 503 and is arranged facing the chuck 502. By measuring the distance that the movable part 503 moves on the chuck 502 with the laser displacement sensor 505, the compression amount of the spring is indirectly judged, so as to judge the elastic force value of the spring, further judge the clamping force of the electric gripper 501 on the product, and then feedback to the electric gripper 501 to ensure that the electric gripper 501 does not clamp the plastic housing 10 excessively, avoiding deformation and damage of the plastic housing 10.

[0030] As Figure 2 、 Figure 3 shown in the figure, in some embodiments, the movable part 503 includes a guide rod 5031 slidably installed on the chuck 502, a clamping plate 5032 located at the end of the guide rod 5031, and an installation plate 5033. The laser displacement sensor 505 is located on the installation plate 5033. A silica gel sheet 7 is pasted on the surface of the clamping plate 5032 in contact with the product, and anti-slip lines are provided on the silica gel sheet 7. The movable part 503 also includes a plurality of reset components fixed between the chuck 502 and the clamping plate 5032. The reset of the movable part 503 is realized through the elastic part 504 and the reset components. Specifically, the reset components are composed of a plurality of reset springs 6.

[0031] As Figure 3 shown in the figure, in order to improve the stability of the reset spring 6 and the elastic part 504 during linear movement, in some embodiments, a stabilizing column 8 is provided on the clamping plate 5032 and facing the chuck 502. The stabilizing column 8 is located inside the reset spring 6 and the elastic part 504, inserted into the chuck 502, and slidably connected to the chuck 502.

During the clamping process, the movable part 503 first contacts the outer wall of the plastic housing 10. During the clamping process of the electric gripper 501, the movable part 503 moves on the chuck 502 and compresses the elastic part 504. The distance that the movable part 503 moves on the chuck 502 is measured by the laser displacement sensor 505, and the compression amount of the spring is indirectly judged, so as to judge the elastic force value of the spring, and thus judge the clamping force of the electric gripper 501 on the product. When the clamping force reaches the preset value range, it is then fed back to the electric gripper 501 to ensure that the electric gripper 501 does not excessively clamp the plastic housing 10, avoiding deformation and damage of the plastic housing 10.
