[0036] The following uses specific examples to illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0037] It should be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concept of the present utility model. Therefore, only the components related to the present utility model are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0038] For the purpose of illustration, some exemplary embodiments of the present utility model are described. It should be understood that the present utility model can be implemented in other ways not specifically shown in the drawings.

[0039] As Figures 1 to 12 shown, a clamping and positioning tray 10 for a flange or elbow module in a preferred embodiment of the present utility model is adapted to position and clamp an object 30, so as to facilitate the subsequent alignment and grinding of the object 30, thereby improving the automation and intelligence in the subsequent manufacturing process of the object 30. Among them, the object 30 is a flange or an elbow. In other embodiments, the object 30 can also be other devices that are not easy to position or transport. Specific limitations are not made here and are determined according to the actual situation.

[0040] Specifically, the clamping and positioning tray 10 for the flange or elbow module includes a base 1, a positioning mechanism 2 installed on the base 1, and a clamping mechanism 3. The positioning mechanism 2 is used to position the installation position of the object, and the clamping mechanism 3 clamps or releases the positioned object, thereby realizing the clamping or releasing of the object 30.

[0041] Among them, two positioning mechanisms 2 are provided. The two positioning mechanisms 2 are fixedly installed on the base 1 at a preset angle to position the installation position of the object 30. In this embodiment, the preset angle is 90°. That is, there is a first included angle between the two positioning mechanisms 2, and this first included angle is 90°. The purpose of such a setting is: to facilitate positioning the center of the base 1, so as to accurately position the installation position of the object 30 and improve the positioning and clamping efficiency.

[0042] The positioning mechanism 2 includes a positioning base 21 having a positioning groove 23 and a positioning block 22 that can move relative to the positioning groove 23 to adjust its position. The position adjustment of the positioning block 22 can be carried out according to the change in the model and / or category of the target object 30. For example, when the model of the target object 30 is larger, the positioning block 22 is closer to the end position of the positioning groove 23, and the end position of the positioning groove 23 is arranged close to the edge position of the base 1; when the model of the target object 30 is smaller, the positioning block 22 is farther away from the end position of the positioning groove 23. When the model of the target object 30 remains unchanged, the position of the positioning block 22 on the positioning groove 23 does not change, so that the target object 30 can be quickly positioned, thereby improving production efficiency and accuracy.

[0043] The positioning block 22 has a positioning portion, and the positioning portion has a first positioning edge 221 and a second positioning edge 222 connected to the first positioning edge 221. A second included angle is formed between the first positioning edge 221 and the second positioning edge 222, and the second included angle is a right angle or an obtuse angle.

[0044] The positioning block 22 has a protrusion that engages with the positioning groove. The positioning block 22 is inserted into the positioning groove through the protrusion to fix the relative position between the positioning block 22 and the positioning base 21. The positioning module further includes a locking member 24, and the locking member 24 is disposed through the positioning block 22 to fix the position of the positioning block 22 relative to the positioning groove. In this embodiment, the locking member 24 is a bolt, and the bolt is threadedly connected to the positioning block 22 to lock the positioning block 22 and the positioning base 21.

[0045] In one embodiment, when the target object 30 is a flange, the flange is not installed in the mold or the frame, so at this time the flange is an exposed bare flange. In order for the flange or elbow module to be firmly connected to the bare flange with the clamping positioning tray 10, the second included angle between the first positioning edge 221 and the second positioning edge 222 is an obtuse angle, and the obtuse angle can be clamped and fixed with the circumferential surface of the bare flange, thereby positioning and clamping the bare flange.

[0046] In another embodiment, when the target object 30 is an elbow, the elbow is accommodated in the module 20, and the module 20 is in the shape of a cube. At this time, the second included angle between the first positioning edge 221 and the second positioning edge 222 of the positioning portion is a right angle, and the positioning block 22 with a right second included angle can engage with the frame of the module 20, thereby clamping the module 20, and then clamping and positioning the elbow fixed in the module 20.

[0047] Correspondingly, the clamping mechanism 3 is located on the extension line of the symmetry axis of the two positioning mechanisms 2, so as to jointly position the central position of the base 211 with the two positioning mechanisms 2, and then be able to position the installation position of the target 30. Moreover, the clamping mechanism 3 can form a stable triangular structure with the two positioning mechanisms 2, so as to improve the stability of the clamping and positioning tray 10 for flange or elbow modules.

[0048] The clamping mechanism 3 includes a transmission lead screw 34 and a clamping block 32 threadedly connected to the transmission lead screw 34. The transmission lead screw 34 rotates under the action of an external force to drive the clamping block 32 to move towards or away from the positioning mechanism, and then clamp or release the target 30. Wherein, the external force can be mechanical force or human force, which is not specifically limited here and depends on the actual situation.

[0049] The clamping mechanism includes a clamping base 31 having a guide groove 33. At least part of the transmission lead screw 34 is received in the guide groove 33, and the clamping block 32 is partially received in the guide groove 33 to be threadedly connected to the transmission lead screw 34. The sliding coefficient between the clamping block 32 and the guide groove 33 can also be set according to the actual situation. During the actual production process, in order to facilitate the sliding between the clamping block 32 and the guide groove 33, the sliding coefficient between the clamping block 32 and the guide groove 33 should be small, so as to facilitate the adjustment of the position of the sliding block. However, it should not be too small to avoid relative displacement between the clamping block 32 and the guide groove 33 during the subsequent grinding process, affecting the accuracy of the subsequent manufacturing process.

[0050] The clamping block 32 has an initial position and a target position; when located at the initial position, the clamping block 32 is located at the first end of the guide groove 33, and the first end is the end close to the edge of the base 1; when the clamping block 32 slides along the guide groove 33 to clamp the target 30, the clamping block 32 moves from the initial position to the target position. Among them, the target position can be set according to different models of the target 30. Taking the flange as an example, the target positions of flanges with different diameters are different.

[0051] In order to further improve the accuracy of the clamping and positioning tray 10 for flange or elbow modules, the positioning mechanism 2 further includes a positioning member 22 disposed in the positioning groove 23, and the sliding block is sleeved on the positioning member 22 to be slidably connected to the positioning member 22.

[0052] In order to further improve the accuracy of the clamping and positioning tray 10 for flange or elbow modules, at least one positioning mark 11 is provided on the base 1. The orthographic projection of the target 30 on the base 1 when placed on the positioning mechanism 2 is adapted to the shape of the positioning mark 11. That is, in this embodiment, the shape of the positioning mark 11 is circular and / or square. Taking the target 30 as a flange as an example, the positioning mark 11 is circular; taking the target 30 as an elbow as an example, since the elbow is fixed in the cube-shaped tray 20, the positioning mark 11 is square.

[0053] The clamping and positioning tray 10 for the flange or elbow module further includes a heightening bottom plate, which is installed below the base 1. There are multiple heightening bottom plates, and the multiple heightening bottom plates are respectively arranged at the edges of the base 1. In this embodiment, there are four heightening bottom plates, and the four heightening bottom plates are respectively installed at the four corners of the base 1, so as to raise the base 1 to reduce the contact surface.

[0054] As Figure 11 and Figure 12 shown, the base 1 may also be provided with a U-shaped notch 12, which is used to dock with the target device during subsequent manufacturing processes, so as to facilitate the transportation, grinding and other processes of the target object 30. The U-shaped notch 12 can be set according to the actual situation. For example, the base 1 may not be provided with the U-shaped notch 12.

[0055] In summary: By providing the positioning mechanism 2 and the clamping mechanism 3, the positioning mechanism 2 can position the installation angle of the target object 30 so that the target object 30 is installed at a preset angle to achieve the positioning effect; while the clamping mechanism 3 clamps the positioned target object 30 to facilitate subsequent manufacturing processes such as transportation and grinding of the target object 30, thereby improving the automation and intelligence of the subsequent manufacturing of the target object 30; among them, there are two positioning mechanisms 2, and there is a first included angle between the two positioning mechanisms 2, and the first included angle is 90°, and the clamping mechanism 3 is located on the extension line of the symmetry axis of the two positioning mechanisms 2, so as to correspond to the center of the base 1, thereby facilitating the positioning of the installation position of the subsequent target object 30 and improving the positioning accuracy and production efficiency of the target object 30.

[0056] The above embodiments are only illustrative of the principles and effects of the present invention, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
