[0039] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0042] See also Figures 1 to 5 The embodiment of the present application provides a processing and clamping fixture 100, which includes a rotating shaft 10, a fixture seat 11 and at least two fixing seats.

[0043] The fixing seats are arranged side by side and spaced from each other; the rotating shaft 10 is movably connected between the fixing seats along its own axial direction. The rotating shaft 10 and the fixing seats are easy to disassemble and assemble, and are convenient for maintenance and replacement of the rotating shaft 10 and the fixing seats.

[0044] The fixture seat 11 has a clamping surface 112 for placing the fixture seat 11 . The fixture seat 11 is disposed between any two adjacent fixing seats and is detachably connected to the rotating shaft 10 .

[0045] It is understandable that, in the process of assembling the workpiece to be processed onto the clamping surface 112 , the workpiece to be processed needs to be calibrated so that the processing surface of the workpiece to be processed can be aligned with the processing device.

[0046] For ease of understanding, the present application defines that the processing device is located on the upper side of the processing clamping fixture 100 along the height direction. After the workpiece to be processed is assembled to the clamping surface 112, it is necessary to calibrate the workpiece to be processed. The surface of the calibrated workpiece to be processed that is aligned with the processing device facing upward is the surface to be processed.

[0047] It should be noted that the specific assembly relationship and position of the processing device and the processing fixture 100 are not limited and should be based on the actual situation. Correspondingly, the processing surface to be processed should also follow the position change of the processing device.

[0048] The rotating shaft 10 can be controlled to rotate around its own axis relative to each fixed seat and drive the fixture seat 11 to rotate synchronously. One end of the rotating shaft 10 along its own axial direction is movably connected to a fixed seat to form a rotating fulcrum, and the other end can be controlled to rotate around the rotating fulcrum and drive the fixture seat 11 to rotate synchronously.

[0049] For ease of understanding, in this application, a spatial rectangular coordinate system O-XYZ is established with the rotation fulcrum as the origin. The Z-axis direction of the spatial rectangular coordinate system O-XYZ is parallel to the height direction, and the Y-axis direction is parallel to the axial direction of the rotating shaft 10. Correspondingly, the X-axis is perpendicular to both the Z-axis and the Y-axis, and the plane where the X-axis and the Y-axis are located is a horizontal plane. Based on the spatial rectangular coordinate system O-XYZ, the positive half axis of the X-axis is defined as the left side, the negative half axis of the X-axis is defined as the right side, the positive half axis of the Y-axis is defined as the front side, the negative half axis of the Y-axis is defined as the back side, the positive half axis of the Z-axis is defined as the upper side, and the negative half axis of the Z-axis is defined as the lower side.

[0050] See also Figure 2 In the specific operation process of the processing clamping fixture 100, the processing clamping fixture 100 is defined to have an initial processing state. When the processing clamping fixture 100 is in the initial processing state, the clamping surface 112 of the fixture seat 11 faces the upper side and is arranged opposite to the processing device. In this way, after the workpiece to be processed is assembled on the clamping surface 112, the workpiece to be processed is defined to have a left side, right side, front side, rear side, upper side and lower side corresponding to the left side, right side, front side, rear side, upper side and lower side mentioned above, wherein the lower side is fitted and fixed to the clamping surface 112.

[0051] See also Figure 3Based on the initial processing state of the processing fixture 100, the rotating shaft 10 is controlled to rotate toward the left side relative to each fixed seat around its own axis until the clamping surface 112 of the fixture seat 11 faces the left side, that is, the rotating shaft 10 rotates 90° to the left around its own axis. In this way, the right side of the workpiece to be processed mounted on the clamping surface 112 is rotated to face the upper side, and the right side of the workpiece to be processed can face the processing device located on the upper side of the processing fixture 100. After the calibration operation, the right side of the workpiece to be processed can be aligned with the processing device, so that the processing device can perform processing operations on the right side of the workpiece to be processed. In this way, the right side of the workpiece to be processed is the surface to be processed. Therefore, the state in which the clamping surface 112 of the processing fixture 100 faces the left side so that the right side of the workpiece to be processed faces the processing device is defined as the first processing state, that is, the processing fixture 100 has the first processing state.

[0052] See also Figure 4 Based on the initial processing state of the processing fixture 100, the rotating shaft 10 is controlled to rotate toward the right side relative to each fixed seat around its own axis until the clamping surface 112 of the fixture seat 11 faces the right side, that is, the rotating shaft 10 rotates 90° to the right side around its own axis. In this way, the left side of the workpiece to be processed mounted on the clamping surface 112 is rotated to face the upper side, and the left side of the workpiece to be processed can face the processing device located on the upper side of the processing fixture 100. After the calibration operation, the left side of the workpiece to be processed can be aligned with the processing device, so that the processing device can perform processing operations on the left side of the workpiece to be processed. In this way, the left side of the workpiece to be processed is the surface to be processed. Therefore, the clamping surface 112 of the processing fixture 100 faces the right side, so that the state in which the left side of the workpiece to be processed faces the processing device is defined as the second processing state, that is, the processing fixture 100 has the second processing state.

[0053] See also Figure 5 Based on the initial processing state of the processing fixture 100, the end of the rotating shaft 10 that is away from the rotating fulcrum is controlled to rotate around the rotating fulcrum until the clamping surface 112 of the fixture seat 11 faces the front side, that is, the axis of the rotating shaft 10 rotates from being parallel to the Y axis to being parallel to the Z axis, and the rotating fulcrum of the rotating shaft 10 rotates 90°, so that the rear side of the workpiece to be processed mounted on the clamping surface 112 moves to face the upper side, and the rear side of the workpiece to be processed can face the processing device located on the upper side of the processing fixture 100, and then after the calibration operation, the rear side of the workpiece to be processed can be aligned with the processing device, so that the processing device can perform processing operations on the rear side of the workpiece to be processed. In this way, the rear side of the workpiece to be processed is the surface to be processed, therefore, the clamping surface 112 of the processing fixture 100 is defined as facing the front side, so that the state in which the rear side of the workpiece to be processed faces the processing device is defined as the third processing state, that is, the processing fixture 100 has the third processing state.

[0054] It is understandable that, since the lower side of the workpiece to be processed is closely connected to the clamping surface 112, it is not necessary to control the rotation axis of the rotating shaft 10 to rotate to the clamping surface 112 toward the lower side. In this way, in the aforementioned embodiment, the present application can control the clamping surface 112 to switch between four different directions, namely, the upper side, the left side, the right side, and the front side, by controlling the rotation axis 10 to rotate around its own axis and the rotation fulcrum, so as to adjust the workpiece to switch between four different surfaces to be processed.

[0055] It should be supplemented that the first processing state and the second processing state of the processing device can be switched to each other. Specifically, the switching of the processing device from the first processing state to the second processing state is explained as an example. Based on the first processing state of the processing clamping fixture 100, the rotating shaft 10 is controlled to rotate relative to each fixed seat around its own axis toward the right side, so that the clamping surface 112 of the workpiece to be processed facing the left side is rotated to the right side, that is, the rotating shaft 10 rotates 180° to the right side around its own axis. In this way, the left side surface of the workpiece to be processed assembled on the clamping surface 112 is rotated to face the upper side, and the left side surface of the workpiece to be processed can face the processing device located on the upper side of the processing clamping fixture 100. After the calibration operation, the left side surface of the workpiece to be processed can be aligned with the processing device, so that the processing device can perform processing operations on the left side surface of the workpiece to be processed.

[0056] It should be supplemented that, in the process of controlling the rotating shaft 10 to rotate around its own axis, the clamping surface 112 of the fixture seat 11 can switch to multiple directions, including but not limited to the upper side, left side and right side in the aforementioned embodiment. Similarly, in the process of controlling the rotating shaft 10 to rotate around the rotation fulcrum, the clamping surface 112 of the fixture seat 11 can switch to multiple directions, including but not limited to the front side in the aforementioned embodiment.

[0057] The processing clamping fixture 100 provided in the embodiment of the present application can switch the clamping surface 112 of the fixture seat 11 to multiple directions by controlling the rotation of the rotating shaft 10 around its own axis and controlling the rotation of the rotating shaft 10 around the rotation fulcrum, thereby enabling the workpiece to be processed assembled on the clamping surface 112 to switch multiple processing surfaces. In this way, the processing clamping fixture 100 has a simple structure and is easy to operate, which is beneficial to improving processing efficiency and reducing production costs.

[0058] For some examples, see Figures 1 to 5 , it is defined that the fixed seat that forms a rotation fulcrum with the rotating shaft 10 among all the fixed seats is the first fixed seat 12, and a first fixed groove 121 is formed on the first fixed seat 12. The first fixed groove 121 extends along the axial direction of the rotating shaft 10 and passes through one side of the first fixed seat 12.

[0059] In the embodiments of the present application, the end of the rotating shaft 10 that is movably connected to the fixed seat and forms a rotating fulcrum is defined as the rotating end, and the end of the rotating shaft 10 that is away from the rotating fulcrum is defined as the free end.

[0060] It can be understood that the rotating end of the rotating shaft 10 is correspondingly assembled in the first fixed groove 121, and the free end of the rotating shaft 10 extends out through the opening of the first fixed groove 121 that penetrates the axial direction of the rotating shaft 10, and is connected to another fixed seat. The rotating end of the rotating shaft 10 and the first fixed groove 121 can play a limiting role for the rotating end of the rotating shaft 10, and the rotating end of the rotating shaft 10 is in contact with the groove wall of the first fixed groove 121. The first fixed groove 121 extends along the axial direction of the rotating shaft 10 to increase the contact area between the rotating shaft 10 and the groove wall of the first fixed groove 121, thereby facilitating the stability of the assembly of the rotating shaft 10 and the first fixed seat 12.

[0061] The bottom wall of the first fixing groove 121 near the end face of the rotating shaft 10 is concave to form a rotation space. It can be understood that when the rotating end of the rotating shaft 10 is controlled to rotate around the rotating fulcrum, the end face of the rotating end will swing downward around the rotating fulcrum. Therefore, the rotation space can provide sufficient accommodation space for the swing of the rotating end of the rotating shaft 10 to ensure the normal operation of the processing clamping fixture 100.

[0062] For some examples, see Figures 1 to 5 , the fixed seat away from the rotation fulcrum among all the fixed seats is defined as the second fixed seat 13 , and a second fixed groove 131 is formed on the second fixed seat 13 , and the second fixed groove 131 extends along the axial direction of the rotating shaft 10 .

[0063] It can be understood that the free end of the rotating shaft 10 is correspondingly assembled in the second fixed groove 131 and fits with the groove wall of the second fixed groove 131. The second fixed groove 131 extends along the axial direction of the rotating shaft 10 to increase the contact area between the rotating shaft 10 and the groove wall of the second fixed groove 131, which is beneficial to improve the stability of the assembly of the rotating shaft 10 and the second fixing seat 13.

[0064] The second fixing groove 131 penetrates the opposite sides of the first fixing seat 12 along the axial direction of the rotating shaft 10. It can be understood that the opening of the second fixing groove 131 penetrating along the axial direction of the rotating shaft 10 can facilitate the assembly of the rotating shaft 10. At the same time, the opening of the second fixing groove 131 penetrating along the axial direction of the rotating shaft 10 can facilitate the user to hold the rotating shaft 10, so as to control the free end of the rotating shaft 10 to rotate around the rotating fulcrum relative to the rotating end, thereby facilitating the improvement of processing efficiency.

[0065] The specific number of the fixing bases is not limited. Figures 1 to 5 There are two fixing seats, and the two fixing seats are spaced apart from each other and are movably connected to the opposite ends of the rotating shaft 10 along its own axial direction.

[0066] Among them, the fixed seat of the two fixed seats that forms a rotation fulcrum with the rotating shaft 10 is the first fixed seat 12 , and the fixed seat away from the rotation fulcrum is the second fixed seat 13 .

[0067] It can be understood that the two fixing seats can make the relative ends of the rotating shaft 10 along its own axial direction bear force evenly, so as to achieve stable assembly of the rotating shaft 10. The processing and clamping fixture 100 of the present application has a simple structure, and the fixing seats and the rotating shaft 10 are easy to disassemble and assemble, which is conducive to improving the user experience.

[0068] The specific matching method between the first fixing seat 12 and the rotating shaft 10, and the second fixing seat 13 and the rotating shaft 10 is not limited. Figures 1 to 5 The processing and clamping fixture 100 also includes a fixing pin 17 , which is detachably connected between each fixing seat and the rotating shaft 10 .

[0069] It can be understood that in the specific operation process of machining the clamping fixture 100, when it is necessary to control the rotation of the rotating shaft 10 around its own axis relative to the fixed seat, and control the rotation of the rotating shaft 10 around the rotation fulcrum, it is necessary to pull the fixing pin 17 out from the fixed seat 12 and the rotating shaft 10, so as to facilitate the user to control the movement of the rotating shaft 10 according to actual needs, so that the processing surface of the workpiece to be processed can be aligned with the processing device, thereby realizing the processing operation.

[0070] In some embodiments where the number of fixed seats is two, and the fixed seat that forms a rotation fulcrum with the rotating shaft 10 is the first fixed seat 12, and the fixed seat away from the rotation fulcrum is the second fixed seat 13, the fixing pin 17 is detachably arranged and connected between each first fixed seat 12 and the rotating shaft 10, and between the second fixed seat and the rotating shaft 10.

[0071] During the specific operation of the machining fixture 100, when it is necessary to control the rotating shaft 10 to rotate around its own axis relative to the fixed seat, and control the rotating shaft 10 to rotate around the rotation fulcrum, it is necessary to pull the fixing pin 17 out from the corresponding first fixed seat 12 and the rotating shaft 10, and the second fixed seat 13 and the rotating shaft 10, so as to facilitate the user to control the movement of the rotating shaft 10 according to actual needs, so that the processing surface of the workpiece to be processed can be aligned with the processing device, thereby realizing the processing operation.

[0072] Correspondingly, after controlling the movement of the rotating shaft 10 to align the processing surface of the workpiece to be processed with the processing device, it is necessary to pass the fixing pin 17 through and connect between the first fixing seat 12 and the rotating shaft 10, and between the second fixing seat 13 and the rotating shaft 10, so as to realize the fixed connection between the first fixing seat 12 and the rotating shaft 10, and the second fixing seat 13 and the rotating shaft 10, thereby realizing the stable assembly of the rotating shaft 10, and then ensuring the stability of the jig seat 11 and the workpiece to be processed, which is beneficial to improving the safety of the processing operation.

[0073] The specific style of the rotating shaft 10 is not limited. In some embodiments, see Figure 3 and Figure 4 The first fixing holes 101 penetrating the rotating shaft 10 are provided at opposite ends of the rotating shaft 10 along its axial direction, and the first fixing hole 101 has opposite first and second ends. Each fixing seat is provided with a matching hole connected to the first fixing hole 101 for the fixing pin 17 to pass through.

[0074] It is understandable that the fixing pin 17 needs to pass through the first fixing hole 101 and the matching hole in sequence to achieve fixed connection between the first fixing seat 12 and the rotating shaft 10 , and between the second fixing seat 13 and the rotating shaft 10 .

[0075] The rotating shaft 10 can be controlled to rotate around its own axis until the first end is connected to the matching hole and the clamping surface 112 is oriented to the first preset direction, or the second end is connected to the matching hole and the clamping surface 112 is oriented to the second preset direction, and the first preset direction is opposite to the second preset direction.

[0076] It can be understood that, in the process of controlling the rotating shaft 10 to rotate around its own axis and switching the first fixing hole 101 from the first end to the matching hole to the second end to the matching hole, the angle of rotation of the rotating shaft 10 around its own axis is 180°. Therefore, according to the content of the embodiment in which the processing device switches from the first processing state to the second processing state, it can be known that in the process of the processing device switching from the first processing state to the second processing state, the rotating shaft 10 rotates 180° around its own axis. In this way, when the processing fixture 100 is in either the first processing state or the second processing state, the first end is connected to the matching hole, and correspondingly, when the processing fixture 100 is in the other of the first processing state and the second processing state, the second end is connected to the matching hole.

[0077] The specific opening position of the matching hole is not limited. In some embodiments, the first fixing groove 121 and the second fixing groove 131 are both provided with matching holes that are connected to the first fixing hole 101 for the fixing pin 17 to pass through.

[0078] See also Figure 3 For ease of understanding, the present application defines that when the machining fixture 100 is in the first machining state, the first end is connected to the mating hole. In this way, the first preset direction of the clamping surface 112 is the direction of the clamping surface 112 facing the left side. Correspondingly, the right side surface of the workpiece to be processed assembled on the clamping surface 112 can face the processing device located on the upper side of the machining fixture 100. After calibration, the right side surface of the workpiece to be processed can be aligned with the processing device, so that the processing device can perform processing operations on the right side surface of the workpiece to be processed.

[0079] See also Figure 4In this application, it is defined that when the machining clamping fixture 100 is in the second machining state, the second end is connected to the matching hole. In this way, the first preset direction of the clamping surface 112 is the direction of the clamping surface 112 facing the right side. Correspondingly, the left side surface of the workpiece to be processed assembled on the clamping surface 112 can face the processing device located on the upper side of the machining clamping fixture 100. After calibration operation, the left side surface of the workpiece to be processed can be aligned with the processing device, so that the processing device can perform processing operations on the left side surface of the workpiece to be processed.

[0080] In the present application, by rotating the rotating shaft 10, the first end or the second end of the first fixing hole 101 can be controlled to align with the matching hole according to actual needs, so that the processing fixture 100 can be switched between the first processing state and the second processing state. The operation is simple and conducive to improving the processing efficiency.

[0081] For some examples, see Figure 2 The shaft 10 has a second fixing hole 102 at both ends thereof along its axial direction, and the second fixing hole 102 is perpendicular to the first fixing hole 101. The matching hole can be connected to the second fixing hole 102 for the fixing pin 17 to pass through.

[0082] It is understandable that the fixing pin 17 needs to pass through the second fixing hole 102 and the matching hole in sequence to achieve fixed connection between the first fixing seat 12 and the rotating shaft 10 , and between the second fixing seat 13 and the rotating shaft 10 .

[0083] The rotating shaft 10 can be controlled to rotate around its own axis until the second fixing hole 102 is connected to the matching hole, and the clamping surface 112 faces a third preset direction, which is perpendicular to the first preset direction and the second preset direction.

[0084] It can be understood that the second fixing hole 102 also has two opposite ends along the direction of penetrating the rotating shaft 10. If the rotating shaft 10 is controlled to rotate around its own axis so that the rotating shaft 10 switches from the first fixing hole 101 to the matching hole docking and connecting, and then switches to the second fixing hole 102 to the matching hole docking and connecting, the angle of rotation of the rotating shaft 10 around its own axis is 90°. Therefore, according to the contents in the embodiment in which the aforementioned processing device has an initial processing state, a first processing state and a second processing state, it can be known that in the process of switching the processing device from the first processing state to the initial processing state, and switching the processing device from the second processing state to the initial processing state, the rotating shaft 10 rotates 90° around its own axis. In this way, when the processing fixture 100 is in the initial processing state, the second fixing hole 102 is docked and connected with the matching hole.

[0085] For ease of understanding, the present application defines that when the processing clamping fixture 100 is in the initial processing state, the second fixing hole 102 is connected to the matching hole, so that the third preset direction of the clamping surface 112 is the direction of the clamping surface 112 toward the upper side. Correspondingly, the upper side surface of the workpiece to be processed mounted on the clamping surface 112 can face the processing device located on the upper side of the processing clamping fixture 100, and then after a calibration operation, the upper side surface of the workpiece to be processed can be aligned with the processing device, so that the processing device can perform processing operations on the upper side surface of the workpiece to be processed.

[0086] For some examples, see Figures 1 to 5 The processing and clamping fixture 100 also includes a limiting member 14, and a limiting groove 141 extending along the axial direction of the rotating shaft 10 is formed on the limiting member 14. The limiting member 14 is correspondingly spliced ​​with the first fixing seat 12, and the rotating shaft 10 is jointly covered by the limiting groove 141 and the first fixing groove 121.

[0087] It is understandable that the limiting member 14 can cooperate with the first fixing seat 12 to ensure stable assembly of the rotating shaft 10 and the first fixing seat 12 .

[0088] When it is necessary to control the rotating shaft 10 to rotate around its own axis, the limiter 14 can limit the rotating end of the rotating shaft 10 between the limiter groove 141 and the first fixed groove 121 to prevent the rotating shaft 10 from being separated from the first fixed seat 12. The user controls the free end of the rotating shaft 10 to rotate around its own axis to drive the entire rotating shaft 10 to rotate around its own axis, thereby driving the fixture seat 11 and the workpiece to be processed to rotate synchronously to adjust the processing surface of the workpiece to be processed. In this way, the processing fixture 100 has a stable structure and is easy to operate, which is conducive to improving processing efficiency.

[0089] When the rotating shaft 10 needs to be controlled to rotate around the rotating fulcrum, the limiting member 14 needs to be separated from the first fixing seat 12 to prevent the limiting member 14 from hindering the rotation of the rotating shaft 10, so as to ensure the normal operation of the processing clamping fixture 100 and flexible use.

[0090] For some examples, see Figures 1 to 5 The limiting member 14 is provided with a through avoidance hole 142 , which is connected to the limiting groove 141 and can be connected and aligned with the matching hole when the limiting member 14 is correspondingly spliced ​​with the first fixing seat 12 .

[0091] For some examples, see Figures 1 to 5The limiting member 14 is provided with first fixing grooves opening toward the first fixing seat 12 and penetrating the limiting member 14 along the axis direction perpendicular to the rotating shaft 10 on both sides thereof, and the first fixing seat 12 is provided with second fixing grooves opening toward the limiting member 14 and penetrating the first fixing seat 12 along the axis direction perpendicular to the rotating shaft 10 on both sides thereof, and when the limiting member 14 is assembled with the first fixing seat 12, the first fixing groove is connected with the second fixing groove correspondingly, and defines a fixing hole connected with the limiting groove 141 and the positioning groove 151;

[0092] The processing and clamping fixture 100 further includes at least two retaining members 16 , and the two retaining members 16 are respectively inserted into corresponding retaining holes.

[0093] It is understandable that the limiting groove 141 and the positioning groove 151 together cover the rotating shaft 10, and the two abutting members 16 are respectively inserted into the corresponding abutting holes and can abut against the rotating shaft 10, so that the assembly of the rotating shaft 10 and the first fixing seat 12 is more stable.

[0094] For some examples, see Figures 1 to 5 The fixture seat 11 includes a clamping portion 111 and a mounting portion 113. The mounting portion 113 is used to be detachably connected to the rotating shaft 10, and a mounting groove 114 extending along the axial direction of the rotating shaft 10 is formed on the mounting portion 113. The rotating shaft 10 is at least partially embedded in the mounting groove 114. The clamping portion 111 is matched to a side of the mounting portion 113 away from the mounting groove 114, and the side of the clamping portion 111 away from the mounting groove 114 is a clamping surface 112.

[0095] It can be understood that when the rotating shaft 10 and the mounting portion 113 are assembled correspondingly, the rotating shaft 10 is at least partially embedded in the mounting groove 114 and fits against the groove wall of the first fixed groove 121, and the mounting groove 114 extends along the axial direction of the rotating shaft 10 to increase the contact area between the rotating shaft 10 and the groove wall of the mounting groove 114, thereby facilitating improving the stability of the assembly of the rotating shaft 10 and the mounting groove 114.

[0096] For some examples, see Figures 1 to 5 The processing fixture 100 further includes at least one positioning member 15, on which a positioning groove 151 extending along the axial direction of the rotating shaft 10 is formed, and the positioning member 15 is spliced ​​with the mounting portion 113, and the mounting groove 114 and the positioning groove 151 jointly cover the rotating shaft 10. It can be understood that the positioning member 15 can cooperate with the mounting portion 113 of the fixture seat 11 to ensure stable assembly of the rotating shaft 10 and the fixture seat 11.

[0097] For some examples, see Figures 1 to 5 The processing and clamping fixture 100 also includes a base 18, and all the fixing seats can be detachably connected to the base 18.

[0098] For some examples, see Figure 5 One end of the rotating shaft 10 along its own axial direction is movably connected to a fixed seat to form a rotation fulcrum, and the other end can be controlled to rotate around the rotation fulcrum and drive the fixture seat 11 and other fixed seats to rotate synchronously.

[0099] The processing clamping fixture 100 further includes a support seat 19 , which is used to be fixedly connected between at least one of the other fixing seats and the base 18 when the rotating shaft 10 is controlled to rotate around the rotation fulcrum until the clamping surface 112 faces the fourth preset direction.

[0100] It can be understood that according to the contents in the embodiment in which the aforementioned processing device has an initial processing state, a first processing state, a second processing state and a third processing state, when the free end of the rotating shaft 10 is controlled to rotate around the rotation fulcrum, the second fixed seat 13 is fixedly matched with the free end of the rotating shaft 10 and can rotate synchronously with the free end of the rotating shaft 10 around the rotation fulcrum. In this way, when the free end of the rotating shaft 10 rotates around the rotation fulcrum until the clamping surface 112 of the fixture seat 11 faces the front side, the present application is fixedly connected between the second fixed seat 13 and the base 18 through the support seat 19, which is conducive to ensuring the structural stability of the processing clamping fixture 100.

[0101] Correspondingly, the fourth preset direction of the clamping surface 112 is the direction of the clamping surface 112 toward the front side. Correspondingly, the rear side surface of the workpiece to be processed mounted on the clamping surface 112 can face the processing device located on the upper side of the processing clamping fixture 100. After calibration operation, the rear side surface of the workpiece to be processed can be aligned with the processing device, so that the processing device can perform processing operations on the rear side surface of the workpiece to be processed.

[0102] The specific connection method between the support base 19 and the base 18, and between the support base 19 and the second fixing base 13 is not limited. Figure 5 The support seat 19 and the base 18 , as well as the support seat 19 and the second fixing seat 13 are detachably connected via a fixing pin 17 .

[0103] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0104] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
