[0026] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the sake of description, only the parts related to the present utility model are shown in the accompanying drawings, rather than all the structures.

[0027] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0029] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0030] With the development of the times, the deburring of the wire threading hole in the head tube has changed from manual deburring to automatic robot deburring, which reduces the labor intensity of workers, improves production efficiency, and ensures product quality. However, there are certain limitations in automatic robot deburring. When deburring the wire threading hole in the head tube, the head tube needs to be fixed and the wire threading hole needs to be limited to a position that meets the settings during automatic robot deburring. In the current prior art, a fixture that can fix the pipe fitting is provided, but this type of fixture can only clamp the pipe fitting and does not consider limiting the position of the wire threading hole in the pipe fitting during clamping. Therefore, in this embodiment, a pipe fitting fixing fixture is provided to solve the above problems. In this embodiment, the fixture for restricting and fixing the pipe fitting is not limited to the pipe fitting with a wire threading hole, and other pipe fittings with holes that require robotic machining can also be used.

[0031] Please refer to Figures 1 to 4 As shown, the pipe fitting fixing fixture is used to fix the pipe fitting with a wire threading hole on its side wall. The pipe fitting fixing fixture includes a mounting base 1, a positioning component 2, and a limiting member 3. The positioning component 2 includes a first positioning member 21 and a second positioning member 22. The first positioning member 21 is fixedly arranged on the mounting base 1, and the second positioning member 22 is movably arranged on the mounting base 1. The second positioning member 22 can move relative to the mounting base 1 and has a clamping position and a separating position. When the second positioning member 22 is in the clamping position, the first positioning member 21 and the second positioning member 22 respectively abut against both ends of the pipe fitting. When the second positioning member 22 is in the separating position, the second positioning member 22 is separated from the pipe fitting. The limiting member 3 is movably arranged on the first positioning member 21. The limiting member 3 can move relative to the first positioning member 21 and has a first position and a second position. When the limiting member 3 is in the first position, one end of the limiting member 3 is inserted into the wire threading hole of the pipe fitting and can limit the pipe fitting from rotating around its own axis, and make the wire threading hole of the pipe fitting face the set direction. When the limiting member 3 is in the second position, the limiting member 3 withdraws from the wire threading hole of the pipe fitting. Specifically, in this embodiment, the first positioning member 21 is fixedly arranged on the mounting base 1 as the positioning reference of the fixture. One end of the pipe fitting is abutted by the first positioning member 21, and then the second positioning member 22 in the separating position is moved towards the clamping position to abut against the other end of the pipe fitting, and the pipe fitting is preliminarily fixed. The pipe fitting can rotate around its own axis. One end of the limiting member 3 is inserted into the wire threading hole of the pipe fitting to limit the pipe fitting from rotating around its own axis and limit the wire threading hole of the pipe fitting to face the set direction (the set direction is the moving direction of the robotic arm of the deburring robot). Then, the second positioning member 22 is continuously moved until it reaches the clamping position. Thus, the first positioning member 21 and the second positioning member 22 clamp the pipe fitting from both ends of the pipe fitting, and then the limiting member 3 is withdrawn from the wire threading hole of the pipe fitting. At this time, the pipe fitting is accurately positioned, meeting the requirements for the position accuracy of the pipe fitting during automatic robot deburring, thereby reducing the labor intensity of workers, improving production efficiency, and ensuring product quality.

[0032] Optionally, as shown in Figures 1 to 3 , the limiting member 3 includes a first connecting portion 31 and a limiting portion 32. The first connecting portion 31 is rotatably connected to the first positioning member 21, and the limiting portion 32 is connected to the first connecting portion 31. When the limiting member 3 is in the first position, the limiting portion 32 is inserted into the wire threading hole of the pipe fitting and can limit the pipe fitting from rotating around its own axis. In this embodiment, the limiting member 3 is rotated by the first connecting portion 31 so that the limiting portion 32 moves between the first position and the second position. When the limiting portion 32 moves to the first position, it can be inserted into the wire threading hole of the pipe fitting, and when the limiting portion 32 moves to the second position, it can be away from the wire threading hole of the pipe fitting. In other embodiments, the first connecting portion 31 can also be slidably connected to the first positioning member 21 and also has a first position and a second position, and the limiting portion 32 can move between the first position and the second position.

[0033] Further, as shown in Figures 1 to 3 , along the axial direction of the pipe fitting, the limiting portion 32 is adjustably connected to the first connecting portion 31. Specifically, in this embodiment, a long strip-shaped opening is formed in the first connecting portion 31, and a bolt is passed through the opening to bolt the limiting portion 32 to the first connecting portion 31. At this time, the limiting portion 32 can adjust its relative position with the first connecting portion 31 along the length direction of the opening, and the adjustment direction is defined as along the axial direction of the pipe fitting. Such a setting can make the limiting portion 32 adapt to the wire threading holes at different positions on the pipe fitting when inserted, improving the adaptability of the fixture. In other embodiments, the limiting portion 32 and the first connecting portion 31 can also be slidably inserted, and the sliding direction of the limiting portion 32 is defined as extending along the axial direction of the pipe fitting.

[0034] Optionally, as shown in Figures 1 to 3 , the first positioning member 21 includes a second connecting portion 211 and a first inserting portion 212. The first inserting portion 212 is connected to the second connecting portion 211. The second connecting portion 211 is fixedly arranged on the mounting seat 1. The pipe fitting is provided with a through hole, and the first inserting portion 212 is used for inserting into one end of the through hole. The first inserting portion 212 is cylindrical and the pipe fitting abuts against the second connecting portion 211. Specifically, the through hole of the pipe fitting is a cylindrical hole, and the diameter of the through hole is adapted to the outer diameter of the first inserting portion 212. In this embodiment, the first positioning member 21 is fixedly arranged on the mounting seat 1 through the second connecting portion 211. Specifically, the second connecting portion 211 is bolted to the mounting seat 1. In this way, it is convenient to adjust the position of the first positioning member 21 on the mounting seat 1.

[0035] Further, as shown in Figures 1 to 3As shown in the figure, the second positioning member 22 includes a third connecting portion 221 and a second insertion portion 222. The second insertion portion 222 is conical, with the large end of the cone connected to the third connecting portion 221. The third connecting portion 221 is movably arranged on the mounting base 1, and the second insertion portion 222 is used for inserting into the other end of the through hole. In this embodiment, the second positioning member 22 is movably arranged on the mounting base 1 through the third connecting portion 221. The conical second insertion portion 222 can be gradually inserted into the through hole by moving. Since the small end of the cone faces the through hole and the conical structure can play a good guiding role, during the process of the second insertion portion 222 inserting into the through hole, the impact damage and wear caused by the second insertion portion 222 to the pipe fitting can be effectively reduced, thus ensuring the quality of the pipe fitting.

[0036] Optionally, as Figures 1 to 3 shown, the pipe fitting fixing jig further includes a first slider 4 and a slide rail 6. The slide rail 6 is fixedly arranged on the mounting base 1. The first slider 4 is slidably connected to the slide rail 6, and the second positioning member 22 is connected to the first slider 4. In this embodiment, by arranging the slide rail 6 on the mounting base 1, the second positioning member 22 can move through the sliding cooperation of the first slider 4 and the slide rail 6.

[0037] Optionally, as Figures 1 to 2 shown, the pipe fitting fixing jig further includes a support assembly 7. The support assembly 7 is arranged on the mounting base 1, and the support assembly 7 is used for supporting the pipe fitting. With such a setting, before moving the second positioning member 22, there is a suitable position to place the pipe fitting, and together with the first positioning member 21, it can support the pipe fitting, which can prevent the pipe fitting from slipping off the first positioning member 21 and replaces the process of workers holding the pipe fitting by hand, thus reducing the workload of workers and facilitating the workers to pick up and place the pipe fitting.

[0038] Furthermore, as Figures 1 to 2 shown, the support assembly 7 includes a support frame 71 and a support seat 72. The support seat 72 is arranged on the mounting base 1. Along the vertical direction, the support frame 71 is adjustably connected to the support seat 72, and the support frame 71 is used for supporting the pipe fitting. Specifically, in this embodiment, the support frame 71 is bolted to the support seat 72, and the support frame 71 can adjust its height along the vertical direction, so that the support frame 71 can adapt to pipe fittings of different diameters, improving the adaptability of the jig. Preferably, the support assembly 7 further includes a locking member for locking or unlocking the relative position of the support frame 71 and the support seat 72. The locking member can be a bolt or the like. In this embodiment, the part of the support frame 71 that supports the pipe fitting is V-shaped. In other embodiments, this part can also be other shapes, such as arc-shaped or U-shaped, as long as it can effectively support the pipe fitting, and no specific limitation is made.

[0039] Even further, as Figures 1 to 3As shown, the pipe fitting fixing fixture further includes a second slider 5. The second slider 5 is slidably connected to the slide rail 6, and the support seat 72 is connected to the second slider 5. In this embodiment, by providing the slide rail 6 on the mounting seat 1, the support seat 72 realizes movement through the sliding fit of the second slider 5 and the slide rail 6.

[0040] Optionally, as Figures 1 to 3 shown, the pipe fitting fixing fixture further includes a driving member 8. The driving member 8 is fixedly arranged on the mounting seat 1. The driving member 8 is in transmission connection with the second positioning member 22. The driving member 8 is used to drive the second positioning member 22 to move between the clamping position and the separating position. In this embodiment, the driving member 8 is a cylinder. In other embodiments, the driving member 8 can also be an electric cylinder.

[0041] The use process of the pipe fitting fixing fixture in this embodiment has the following two methods:

[0042] First, taking the first positioning member 21 as the positioning reference, using the support assembly 7 to carry the pipe fitting. The support frame 71 in the support assembly 7 can move along the vertical direction to adjust the placement height of the pipe fitting, so that the first insertion portion 212 of the first positioning member 21 can be smoothly inserted into one end of the pipe fitting, restricting one end of the pipe fitting. Then, the driving member 8 is used to drive the second positioning member 22 to move from the separating position towards the clamping position. During the movement, the second insertion portion 222 of the second positioning member 22 will gradually be inserted into the other end of the pipe fitting. Before the second insertion portion 222 is completely inserted into the pipe fitting, the first connecting portion 31 in the limiting member 3 rotates, so that the limiting portion 32 of the limiting member 3 moves from the second position to the first position, and the limiting portion 32 is inserted into the wire passing hole of the pipe fitting, restricting the pipe fitting from rotating around its own axis and restricting the wire passing hole of the pipe fitting to face the set direction. Then, continue to move the second positioning member 22 until it reaches the clamping position. The pipe fitting is clamped from both ends of the pipe fitting by the first positioning member 21 and the second positioning member 22. Then, the limiting portion 32 is withdrawn from the wire passing hole of the pipe fitting, exposing the wire passing hole. Then, start the deburring robot to complete the automatic deburring work of the pipe fitting. After deburring is completed, under the drive of the driving member 8, the second positioning member 22 moves to the separating position, and the pipe fitting is taken off from this fixture. In this way, a pipe fitting deburring process is completed.

[0043] Second, other processes remain unchanged. Before driving the second positioning member 22, first rotate the first connecting portion 31 so that the limiting portion 32 is inserted into the wire passing hole of the pipe fitting, restricting the pipe fitting from rotating around its own axis and restricting the wire passing hole of the pipe fitting to face the set direction. Then, drive the second positioning member 22 to move from the separating position towards the clamping position and make the second insertion portion 222 gradually be inserted into the other end of the pipe fitting. The pipe fitting is clamped from both ends of the pipe fitting by the first positioning member 21 and the second positioning member 22.

[0044] As Figure 4As shown, in this embodiment, multiple groups of pipe fitting fixing jigs are installed on the same base plate 9. After the robot automatically deburrs the pipe fitting clamped by one of the jigs, it can automatically jump to the next jig position to start the deburring work, thus realizing automatic production connection, reducing the waiting time when replacing pipe fittings, and improving production efficiency. Exemplarily, four groups of pipe fitting fixing jigs are installed on a base plate 9, and the number of pipe fitting fixing jigs is not specifically limited in this embodiment.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
