[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.
[0028] In order to facilitate the description and understanding of the position, the top surface of the cylindrical shell is defined as the upper surface, the bottom surface is defined as the lower surface, the axis direction is defined as the vertical direction, and the direction parallel to the top surface or the side surface is defined as the horizontal direction.
[0029] The utility model specifically provides a flange turning loading and unloading device, which is mainly used to grab the flange. When in use, the device is arranged at the front end of a manipulator, so that the device can move along with the movement of the manipulator, and then the flange is moved from one position and placed to another position by the manipulator equipped with the device.
[0030] like Figure 1-Figure 8 A preferred embodiment of the utility model is provided, a flange turning loading and unloading device, which is arranged at the front end of a manipulator for picking up and placing flanges, and includes a shell 100, a gripping assembly 200, and a control assembly 300 for controlling the gripping assembly 200, wherein the shell 100 serves as a carrier for setting the gripping assembly 200 and the control assembly 300, and the shell 100 also serves as a carrier for connecting the device to the manipulator.
[0031] Furthermore, the aforementioned shell 100 is a hollow cylinder, and a connection end 101 for connecting to a manipulator is formed at the upper end of the shell 100, and a through hole 1011 connected to the internal cavity of the cylinder is formed at the center of the connection end 101. An inverted cone-shaped placement portion 102 is provided at the middle and lower ends of the shell 100. The placement portion 102 is mainly used to set the grasping component 200. The grasping component 200 is relatively slidably arranged in the shell 100. The space between the upper end of the placement portion 102 of the shell 100 and the inner side of the top of the shell is a receiving chamber 103. The receiving chamber 103 is mainly used to accommodate the control component 300 and can provide a moving space for the control component 300 to move in the vertical direction. The grabbing assembly 200 is movably arranged in the placement portion 102. Here, the movably arranged grabbing assembly 200 means that the grabbing assembly 200 can be slid in the horizontal direction to gather toward the center of the shell 100 or disperse away from the center of the shell 100, that is, the grabbing assembly 200 can slide relatively in the horizontal direction. The part of the control assembly 300 used to control the grabbing assembly 200 can move up and down in the placement portion 102 along the vertical direction, so that the grabbing assembly 200 can be dispersed or gathered in the placement portion 102 along the horizontal direction; when grabbing, the control assembly 300 moves downward to open the grabbing assembly 200 to control the grabbing assembly 200 to grab the flange.
[0032] As shown in Figure 5, an inverted cone-shaped expansion cavity 1021 is formed downward along the top of the placement portion 102, and the expansion cavity 1021 provides a movement space for the part of the control component 300 used to control the grasping component 200 to move downward and expand the grasping component 200. The placement portion 102 is provided with a plurality of grooves 1022 that pass through the upper and lower parts, and the notches of each groove 1022 intersect at the center of the shell, and the grooves 1022 are used to accommodate the grasping component 200; a positioning groove 1023 is provided in the horizontal direction near the lower end of the placement portion 102, and the grooves 1022 are connected with the positioning grooves 1023, and the grooves 1022 and the positioning grooves 1023 together serve as a slideway for the grasping component 200 to slide, and the positioning grooves 1023 ensure that the grasping component 200 will not move along the length direction of the grooves 1022, but only move along the depth direction of the grooves 1022.
[0033] In some embodiments, as shown in FIG. 1 , the grab assembly 200 includes a plurality of spreading arms 201 and a return spring 202. The longitudinal section of the spreading arm 201 is in the shape of a right-angled trapezoid. The side where the oblique waist of the right-angled trapezoid in the spreading arm 201 is located is the spreading surface 2011. The oblique waist is selected as the spreading surface 2011 so that the pressure applied to the oblique surface by the control assembly 300 during the downward movement can move the spreading arm 201 in a direction away from the axis of the housing 100. Positioning ears 2012 are provided on the two side surfaces of the spreading arm 201 adjacent to the spreading surface 2011. The positioning ears 2012 are arranged in the positioning groove 1023 to prevent the spreading arm 201 from moving downward synchronously during the upward and downward movement of the control assembly 300, and can only spread or gather in the horizontal direction. A gripping structure 2013 is provided at the lower end of the spreading arm 201 . The gripping structure 2013 is used to directly contact the flange. When gripping, the flange is relatively fixedly stored on the gripping structure 2013 .
[0034] Specifically, the expansion arm 201 is slidably arranged in the groove 1022, and the slidable arrangement here refers to the sliding of the expansion arm 201 relative to the depth direction of the groove 1022, that is, the expansion arm 201 slides between the notch and the bottom of the groove 1022; the positioning ear 2012 is slidably arranged in the positioning groove 1023, and along with the synchronous sliding of the expansion arm 201 in the groove 1022, the positioning ear 2012 slides synchronously in the positioning groove 1023, and the expansion surface 2011 of each expansion arm 201 is toward the axis of the shell 100, so that it can be ensured that the control component 300 can generate a force on the expansion surface 2011 of each expansion arm 201 when moving up and down, that is, the control component 300 can control the expansion arm 201 by acting on the expansion surface 2011.
[0035] In this embodiment, the return spring 202 is arranged in the groove 1022, and one end of the return spring 202 is pressed against the bottom of the groove 1022, and the other end is pressed against the side of the right-angle waist of the stretching arm 201. The return spring 202 is always in a compressed state, that is, when several stretching arms 201 are at the bottom of the groove 1022 or at the notch of the groove, the return spring 202 always maintains an elastic state for the stretching arm 201, so that each stretching arm 201 is always under the elastic force of the return spring 202 and maintains a movement trend of converging toward the axis of the shell 100.
[0036] A positioning protrusion 1024 is provided at the bottom of the groove 1022, and a positioning hole 2014 corresponding to the positioning protrusion 1024 is opened on the spreading arm 201, the diameter of the positioning hole 2014 is larger than the diameter of the reset spring 202, one end of the reset spring 202 is mounted on the positioning protrusion 1024, and the other end is inserted into the positioning hole 2014, so as to prevent the reset spring 202 from changing its position in a compressed state and causing the reset spring 202 to fall off, so that when the control component 300 moves upward, the spreading arm 201 cannot automatically gather toward the axis of the shell 100 to reduce the opening degree of the grasping structure 2013, so that when the grasping and placement is completed, the grasping structure 2013 can gather toward the middle to facilitate the grasping structure 2013 to detach from the central through hole of the flange.
[0037] like Figure 1-3 As shown, the control assembly 300 is specifically as follows, including a control cylinder 301 and a spreading terminal 302 fixedly connected to the piston rod of the control cylinder. The control cylinder 301 is used to control the spreading terminal 302 to move up and down along the axis of the housing 100, thereby controlling the relative position of the spreading terminal 302 and the spreading inclined surface 2011 of the spreading arm 201; the spreading terminal 302 is used to spread the spreading arm 201 that is in a gathering trend. Specifically, the control cylinder 301 is fixedly arranged on the outside of the connecting end 101 on the housing 100 by bolts, and the piston rod of the control cylinder 301 extends into the accommodating chamber 103 through the through hole 1011 on the connecting end 101, and the end of the piston rod is fixedly connected to the spreading terminal 302, for example, a threaded hole is opened at the center of the surface of the spreading terminal 302 connected to the piston rod, and a thread matching the threaded hole is arranged at the end of the piston rod, and the two can be connected by threads.
[0038] It should be noted that the aforementioned expansion terminal 302 is in the shape of a cone or a frustum, and the side of the cone or frustum-shaped control terminal is the control surface 3021. When the expansion terminal 302 is arranged inside the shell 100, the bottom of the frustum or cone is located at the upper end, so that the bottom of the cone or frustum is fixedly connected to the piston rod of the control cylinder 301; when grabbing the flange, the piston rod of the control cylinder 301 extends to drive the control terminal 302 to move downward. During the downward movement of the control terminal 302, the control surface 3021 of the control terminal 302 and the expansion surface 2011 of the expansion arm 201 slide relative to each other, so that the expansion arm 201 spreads out in a direction away from the axis of the shell 100; conversely, when the piston rod of the control cylinder 301 contracts, the control terminal 302 moves upward, and the expansion arm 201 gathers in a direction away from the axis of the shell 100 under the action of the return spring 202. In short, no matter the expansion arm 201 is in a dispersed or gathered state, under the action of the reset spring 202, the control surface 3021 of the control terminal 302 and the expansion surface 2011 of the expansion arm 201 are always in a state of mutual abutment. Furthermore, when the piston rod of the control cylinder 301 stops at a certain position, the grasping structure 2013 can also maintain an open state of a certain size, so that the grasping structure 2013 can grasp flanges with different through hole sizes.
[0039] It should be noted that the grabbing structure 2013 is composed of an L-shaped structure fixedly arranged at the end of each expansion arm 201, one end of the L-shaped structure is fixed to the lower end of the expansion arm 201, and the other end of the L-shaped structure is facing the side where the straight waist of the right-angled trapezoid in the expansion arm 201 is located, so that an annular groove is formed between several L-shaped structures and the lower end of the expansion arm to fix and grab the flange.
[0040] It should be understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
