Detailed Implementation
[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.
[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0015] Examples, such as Figures 1-4 As shown, this utility model provides a quick-change fixture device for training equipment, including a base plate 1. Two uprights 2 are symmetrically distributed at both ends of the base plate 1. A top plate 3 is provided on the top of the two uprights 2. At least three positioning grooves 31 are spaced apart along the length of the top plate 3. The positioning grooves 31 are used to hold the fixture. The positioning grooves 31 are rectangular in structure. Four positioning holes 32 are symmetrically distributed in pairs near one end of each positioning groove 31. The fixture includes a cross-plate arm 41 and a fixture located at the end of the cross-plate arm 41. The quick-change auxiliary plate 42, the cross plate arm 41 is a rectangular plate structure and its two sides are engaged with the groove wall of the positioning groove 31. The bottom surface of the cross plate arm 41 is engaged with the bottom of the positioning groove 31. The bottom of the cross plate arm 41 is provided with a positioning bolt 43 for engaging with the positioning hole 32. The cross plate arm 41 is provided with 2 to 3 connecting holes 44 at the end away from the positioning bolt 43. The bottom of the fixture located in the middle of the top plate 3 is provided with a vertical suction cup 5 connected to the connecting hole 44. The bottom of the two fixtures near the two sides of the top plate 3 is provided with a three-jaw cylinder 6 and a two-jaw cylinder 7 respectively.
[0016] Specifically, the quick-change auxiliary plate 42 is used to quickly connect with the quick-change main plate at the robot's end effector. The quick-change function of the main and auxiliary plates facilitates the robot's replacement of different fixtures, especially by utilizing the actual clamping structures at the ends of different fixtures to accommodate materials of different shapes. The quick-change main and auxiliary plates have a rotation function, allowing for angle adjustment of the fixtures at the robot's end effector, ensuring the material is placed in the desired position and maintains the required posture. Furthermore, this invention extends the working distance from the clamping end of the fixture to the robot's end effector by employing a cross-plate arm 41, which improves the efficiency of material transfer between workstations with long distance intervals. It also provides vertical suction cups 5, three-jaw cylinders 6, and two-jaw cylinders 7 with different clamping characteristics to clamp materials of different shapes. For example, the vertical suction cup 5 can handle sheet-like materials with relatively small unit areas, the three-jaw cylinder 6 can handle spherical materials, and the two-jaw cylinder 7 can handle cylindrical materials. This ensures the reliability of the device's clamping of different materials, enabling the robot to better complete the corresponding material transfer actions. Therefore, this utility model has a reasonable design, a variety of clamps, is conducive to meeting the requirements of long-span transfer, and is highly practical, thus meeting the working requirements of training equipment.
[0017] To improve the clamping reliability of the three-jaw cylinder 6 for spherical materials, this invention provides a clamping block 61 on the inner clamping side of the three-jaw cylinder 6. The clamping block 61 has a connecting hole 44, and the outer clamping side of the three-jaw cylinder 6 has a connecting bolt for engaging with the connecting hole 44. The clamping block 61 can be made of hard or soft materials; this invention preferably uses a soft material such as a rubber block. Anti-slip textures are provided on the inner side of the rubber block, so that the spherical material and the three-jaw cylinder 6 are no longer in point contact, but rather in surface contact with a certain area, thus improving the clamping reliability of the three-jaw cylinder 6 for spherical materials. For clamping spherical materials of different diameters, the clamping block 61 with different radial thicknesses can be replaced to make its clamping diameter suitable for the material, thereby ensuring the overall utilization rate of the three-jaw cylinder 6.
[0018] To facilitate the installation of the vertical suction cup 5, the vertical suction cup 5 provided by this utility model includes a negative pressure tube 52, which passes through a connecting hole 44. Positioning nuts 51 for positioning the negative pressure tube 52 are provided on the upper and lower surfaces of the connecting hole 44. The positioning nuts 51 are threadedly connected to the negative pressure tube 52. The diameter of the connecting hole 44 for passing through the negative pressure tube 52 can be slightly larger, while the surface area of the positioning nuts 51 should be larger than that of the connecting hole 44. By using two positioning nuts 51 to limit the negative pressure tube 52 from the upper and lower surfaces of the cross-plate arm 41, the installation reliability of the negative pressure tube 52 can be improved.
[0019] Furthermore, the connecting holes 44 on the cross plate arm 41 used to connect the two-claw cylinder 7 are arranged diagonally. The bolts in the connecting holes 44 connect the cross plate arm 41 and the cylinder body of the two-claw cylinder 7. The connection reliability is ensured by the connecting holes 44 and the bolts arranged diagonally, and the number of bolts used is reduced, which helps to reduce the installation workload of the two-claw cylinder 7 and the cross plate arm 41.
[0020] To improve the stability of the fixture and its end clamping structure, this invention not only employs the design of positioning grooves 31 and positioning holes 32 to increase positioning nodes, but also considers increasing the positioning area by designing the dimensions of the top plate 3 and the bottom plate 1 accordingly. For example, the length of both the top plate 3 and the bottom plate 1 is not less than 20cm, and the width of both the top plate 3 and the bottom plate 1 is not less than 8cm. By using top plates 3 and bottom plates 1 with appropriate length and width, the stability of the fixture on the top plate 3 can be improved.
[0021] To improve the spatial coordination performance of this device with other components on the training equipment, the base plate 1 of this utility model is provided with multiple pairs of adjustment holes 11. The adjustment holes 11 are elongated structures and have screws 12 inside for connecting the base plate 1 and the training equipment. By adjusting the relative position of the base plate 1 and the screws 12, the specific position of this device on the training equipment can be adjusted, thereby coordinating with other components and facilitating the development of training content and projects.
[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
