[0056] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0057] See also Figure 1 The embodiment of the present application provides a flip-type pressing jaw 100. The flip-type pressing jaw 100 is used to press a workpiece (not shown). The flip-type pressing jaw 100 includes a connecting component 10, a fixing component 20, a stopper 30 and a pressing component 40.

[0058] Please refer to Figure 2 The connection component 10 includes a mounting member 11, and a mounting groove 111 is provided on the side of the mounting member 11. The fixing component 20 is rotatably arranged on the mounting member 11, and a stop groove 231 is provided on the side of the fixing component 20 facing the mounting member 11. When the fixing component 20 rotates to a first state relative to the mounting member 11, the stop groove 231 is communicated with the mounting groove 111, and one end of the stop member 30 is rotatably arranged in the mounting groove 111. When the fixing component 20 rotates to a first state relative to the mounting member 11, the stop member 30 can be rotated so that the other end of the stop member 30 rotates into the stop groove 231. The pressing member 40 is detachably arranged on the fixing component 20 and moves and rotates with the fixing component 20. The pressing member 40 is used to press the workpiece.

[0059] It can be understood that the first state is roughly as follows Figure 1In the state shown, in the first state, the stop groove 231 is roughly parallel to the mounting groove 111, and the stopper 30 is roughly in the shape of a flat plate. It should be noted that in other embodiments, in the first state, the stop groove 231 and the mounting groove 111 can also be arranged relatively tilted, for example, the tilt angle of the stop groove 231 relative to the mounting groove 111 can be roughly 10°, 20°, 30°, etc., as long as the stop groove 231 is connected to the mounting groove 111, and accordingly, the stopper 30 can be roughly in a bent shape and adapted to the stop groove 231 and the mounting groove 111, as long as the other end of the stopper 30 can be rotated into the stop groove 231, and the embodiment of the present application does not specifically limit this.

[0060] Understandably, if Figure 2 The state shown is roughly the second state. When the fixing component 20 rotates relative to the mounting component 11 to the second state, the pressing member 40 detachably disposed on the fixing component 20 is convenient to be cleaned and replaced.

[0061] The above-mentioned flip-type pressing claw 100 is as follows Figure 1 In the first state shown in FIG. 1 , the workpiece is pressed together. When foreign matter adhering to the pressing member 40 needs to be cleaned or the pressing member 40 needs to be replaced, the other end of the stopper 30 is rotated out of the stopper groove 231 so that the fixing assembly 20 and the pressing member 40 can rotate relative to the mounting member 11. The fixing assembly 20 and the pressing member 40 are rotated relative to the mounting member 11 to the position shown in FIG. Figure 2 In the second state shown, the pressing member 40 can face the staff, the equipment that can clean the foreign matter, or the equipment that can replace the pressing member 40, so as to facilitate the cleaning of the foreign matter on the pressing member 40 or the replacement of the pressing member 40. After the foreign matter on the pressing member 40 is cleaned or the pressing member 40 is replaced, the fixing assembly 20 and the pressing member 40 are rotated relative to the mounting member 11 to the position as shown in FIG. Figure 1 In the first state shown, the stopper 30 is then rotated so that the other end of the stopper 30 is rotated into the stopper groove 231, thereby fixing the fixing assembly 20 and the pressing member 40 so that the flip-type pressing jaw 100 can press the workpiece.

[0062] In this embodiment, the flip-type pressing jaw 100 also includes a limiting assembly 50, which is connected to the mounting member 11 and is used to limit the stop member 30 to prevent the stop member 30 from being disengaged from the stop groove 231 due to vibration, thereby affecting the normal pressing operation of the flip-type pressing jaw 100.

[0063] In this embodiment, mounting grooves 111 are respectively provided on opposite sides of the mounting member 11, and correspondingly, two stop grooves 231 are provided on the side of the fixing assembly 20 facing the mounting member 11, and the number of the stop members 30 and the number of the limiting assemblies 50 are both two, and the two mounting grooves 111, the two stop grooves 231, the two stop members 30 and the two limiting assemblies 50 are provided in a one-to-one correspondence. In this way, by providing the above-mentioned two mounting grooves 111, the two stop grooves 231, the two stop members 30 and the two limiting assemblies 50, the fixing assembly 20 and the pressing member 40 can be rotatably provided on the mounting member 11 in a balanced manner, and the two stop members 30 and the two limiting assemblies 50 can fully stop and limit the fixing assembly 20 and the pressing member 40, so as to ensure the normal pressing operation of the fixing assembly 20 and the pressing member 40, thereby ensuring the pressing strength of the pressing member 40.

[0064] Please refer to Figure 3 and Figure 4 In this embodiment, the connecting assembly 10 further includes a connecting member 12, which is connected to the mounting member 11 and is used to connect to an external power source (not shown). Thus, by providing the connecting member 12, the flip-type pressure claw 100 is connected to the external power source. The external power source may be a linear cylinder or the like.

[0065] In this embodiment, a rotation groove 112 is provided in the middle of the side of the mounting member 11 facing the fixed component 20. The rotation groove 112 is spaced apart from the mounting groove 111, and the rotation groove 112 is located between the two mounting grooves 111. The mounting member 11 is also provided with a rotation shaft hole 113 connecting the mounting groove 111 and the rotation groove 112. There are two rotation shaft holes 113 and they are connected to the two mounting grooves 111 one by one. The fixing assembly 20 includes a rotating portion 21, a rotating shaft 22, a stopper 23 and a connecting portion 24. The rotating portion 21 is rotatably arranged in the rotating groove 112. The rotating shaft 22 is connected to the rotating portion 21 and the end of the rotating shaft 22 is arranged in the rotating shaft hole 113. Specifically, the rotating portion 21 is provided with a transmission hole 211. The rotating shaft 22 passes through the two rotating shaft holes 113 and the transmission hole 211 to achieve connection with the rotating portion 21 and the mounting member 11. The two ends of the rotating shaft 22 are rotatably arranged in the two rotating shaft holes 113 and the middle part of the rotating shaft 22 is fixed to the transmission hole 211. The two ends of the rotating shaft 22 are fixedly arranged in the two rotating shaft holes 113 and the middle part of the rotating shaft 22 is rotatably connected with the transmission hole 211, wherein the "rotational connection" can be connected by a bearing, and the "fixed connection" can be connected by an interference fit, the stopper 23 is connected with the rotating part 21, and the two stopper grooves 231 are arranged at intervals on the side of the stopper 23 facing the rotating part 21 and are respectively located on both sides of the rotating part 21, the connecting part 24 is connected with the side of the stopper 23 away from the rotating part 21, and the lower side of the connecting part 24 is connected with the pressing part 40. In this way, by setting the above-mentioned rotating groove 112, the rotating shaft hole 113 and the specific structure of the fixing component 20, the fixing component 20 can realize the rotational connection with the mounting component 11. Among them, the shape of the connecting part 24 can be set according to the shape adaptability of the pressing part 40, and the embodiment of the present application does not make specific limitations on this.

[0066] In this embodiment, the side of the rotating part 21 facing the mounting member 11 is set as an arc surface. Thus, by limiting the side of the rotating part 21 as an arc surface, the rotating part 21 is easy to rotate in the rotating groove 112 and avoids interference between the rotating part 21 and the mounting member 11.

[0067] In this embodiment, a slope or an arcuate surface is provided on the side of the stopper 23 facing the rotating part 21. Specifically, a portion of the structure on the stopper 23 located above the stopper 30 is provided as a slope, and a arcuate surface is provided on the side of the mounting member 11 facing the stopper 23. In this way, by limiting the setting of the slope or the arcuate surface on the stopper 23 and limiting the setting of the arcuate surface on the mounting member 11, the fixing assembly 20 is facilitated to rotate relative to the mounting member 11 and the interference between the fixing assembly 20 and the mounting member 11 is avoided.

[0068] In this embodiment, each limiting assembly 50 includes a base 51, an elastic member 52 and a ball 53. The base 51 is connected to the mounting member 11 and is separated from the corresponding mounting groove 111. The base 51 is arranged below the mounting groove 111. The elastic member 52 can be a spring. The elastic member 52 is movably embedded in the base 51. Specifically, the base 51 is provided with an embedded blind hole 511, and the elastic member 52 is movably disposed in the embedded blind hole 511. One end of the ball 53 is connected to the elastic member 52, and the other end of the ball 53 passes through the mounting member 11 and protrudes into the mounting groove 111. A limiting groove 31 adapted to the other end of the ball 53 is provided on the side of the stop member 30 facing the limiting assembly 50. The ball 53 extends into the limiting groove 31 under the elastic force of the elastic member 52 to limit the stop member 30. In this way, when the stopper 30 is rotated to the installation groove 111, since the ball 53 is spherical, the stopper 30 abuts against the ball 53 and squeezes the ball 53 downward, and the ball 53 compresses the elastic member 52 downward. When the stopper 30 is rotated to the installation groove 111, the limiting groove 31 of the stopper 30 is arranged roughly opposite to the ball 53. Since the limiting groove 31 of the stopper 30 does not squeeze the ball 53, the ball 53 and the elastic member 52 are no longer subjected to force, and the elastic member 52 releases the elastic force to drive the ball 53 to move upward, so that the ball 53 extends into the limiting groove 31, thereby limiting the stopper 30. The process of rotating the stopper 30 out of the installation groove 111 is roughly similar to the process of rotating the stopper 30 to the installation groove 111, and the embodiment of the present application will not be repeated.

[0069] In this embodiment, a ball groove 114 is provided between the mounting groove 111 and the base 51, and penetrates the mounting member 11. One end of the ball groove 114 facing the base 51 is adapted to the ball 53, and the other end of the ball 53 passes through the ball groove 114 and protrudes into the mounting groove 111. The shape of the ball groove 114 is substantially conical. In this way, by providing the ball groove 114 on the mounting member 11, the ball 53 can be adapted to be arranged in the ball groove 114 and the ball 53 can protrude into the mounting groove 111, and the ball 53 is stopped by the ball groove 114 to prevent the ball 53 from being separated from the elastic member 52.

[0070] In this embodiment, each limiting assembly 50 further includes a fastener 54, which passes through the corresponding base 51 to be connected to the mounting member 11, and the fastener 54 and the elastic member 52 are spaced apart in the base 51. Specifically, the base 51 is further provided with a fastening hole 512, which is spaced apart from the embedded blind hole 511, and the fastener 54 can be a screw, which passes through the fastening hole 512 to be threadedly connected to the mounting member 11. In this way, by providing the above-mentioned fastener 54, the base 51 is connected to the mounting member 11.

[0071] In this embodiment, the flip-type pressure claw 100 also includes a rotating pin 60, the number of which is equal to and one-to-one corresponding to the number of the stopper 30, each rotating pin 60 is rotatably arranged on the mounting member 11 and penetrated in the mounting groove 111, and one end of the stopper 30 is rotatably sleeved on the corresponding rotating pin 60, specifically, a connecting hole 513 is also provided on the base 51 of the limiting assembly 50, and a through hole 32 is provided at one end of the stopper 30, and the rotating pin 60 passes through the mounting member 11, the mounting groove 111 and the through hole 32 of the stopper 30 and is connected to the connecting hole 513 of the base 51, wherein the rotating pin 60 and the stopper 30 are rotatably connected, and the rotating pin 60 and the connecting hole 513 can be threaded. In this way, by setting the above-mentioned rotating pin 60, the stopper 30 can achieve the effect of being rotatably arranged in the mounting groove 111. In addition, by providing a connection hole 513 on the base 51 , the connection between the limiting assembly 50 , the mounting member 11 and the stopper 30 is made more stable.

[0072] The flip-type pressing claw 100 provided in the embodiment of the present application, through the cooperation of the connecting assembly 10, the fixing assembly 20, the stopper 30 and the pressing piece 40, can clean the foreign matter on the pressing piece 40 and replace the pressing piece 40 only by rotating the fixing assembly 20 and the pressing piece 40. The cleaning and replacement of the pressing piece 40 is convenient and fast, which helps to save cleaning and replacement time, improve production efficiency, and reduce labor costs. In addition, the fixing assembly 20 and the pressing piece 40 are fixed by the stopper 30, so that the pressing piece 40 will not rotate when the flip-type pressing claw 100 presses the workpiece, and the pressing strength of the pressing piece 40 will not be affected.

[0073] The flip-type pressing jaw 100 provided in the embodiment of the present application further limits the stopper 30 through the cooperation of the limiting assembly 50 , thereby ensuring the normal pressing operation of the flip-type pressing jaw 100 .

[0074] The embodiment of the present application also provides a pressing device (not shown). The pressing device is used to press the workpiece, and the pressing device includes a power source (not shown) and the flip-type pressing claw 100 as described in the above technical solution. The power source is connected to the connecting member 12 of the connecting assembly 10, and the power source is used to drive the flip-type pressing claw 100 to move so that the pressing member 40 presses the workpiece. Among them, the power source can be a linear cylinder or other functional structure that can drive the flip-type pressing claw 100 to move.

[0075] The improved pressing device of the embodiment of the present application, through the cooperation of the connecting component 10, the fixed component 20, the stopper 30, the pressing component 40 and the limiting component 50 in the flip-type pressing claw 100, can clean the foreign matter on the pressing component 40 and replace the pressing component 40 only by rotating the fixed component 20 and the pressing component 40. The cleaning and replacement of the pressing component 40 are convenient and fast, which helps to save cleaning and replacement time, improve production efficiency, and reduce labor costs. In addition, the fixing component 20 and the pressing component 40 are fixed by the stopper 30, and the stopper 30 is limited by the limiting component 50, so that the pressing component 40 will not rotate when the flip-type pressing claw 100 presses the workpiece, and the pressing strength of the pressing component 40 will not be affected, thereby ensuring the normal pressing operation of the flip-type pressing claw 100.
