[0052] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0053] This embodiment provides a connection device, such as Figure 1-Figure 2 As shown, the connecting device includes a first connecting member 100 , a second connecting member 200 and a quick release mechanism 400 . The quick release mechanism 400 is disposed between the first connecting member 100 and the second connecting member 200 , so that the first connecting member 100 is selectively connected to the second connecting member 200 through the quick release mechanism 400 .

[0054] Among them, the first connecting member 100 can be specifically a carrier, a fixture, etc., the second connecting member 200 is a mounting seat, a base, etc., the first connecting member 100 is arranged on the second connecting member 200, the second connecting member 200 is used to support the first connecting member 100, the second connecting member 200 provides support for the first connecting member 100 and ensures the stability of the first connecting member 100; the first connecting member 100 and the second connecting member 200 can also be two plates that need to be connected. This embodiment does not limit the types of the first connecting member 100 and the second connecting member 200. The first connecting member 100 and the second connecting member 200 can be any two connecting members that need to be installed or connected.

[0055] Among them, the appearance of the first connecting member 100 is similar to a rectangular structure. The height direction of the first connecting member 100 is defined as the first direction, and the first direction is marked by D1. The length direction of the first connecting member 100 is defined as the second direction, and the second direction is marked by D2. The width direction of the first connecting member 100 is defined as the third direction, and the third direction is marked by D3. The first direction, the second direction and the third direction are perpendicular to each other. The first direction, the second direction and the third direction only represent spatial directions and have no practical meaning.

[0056] In the connection device provided in this embodiment, the quick release mechanism 400 is arranged between the first connection member 100 and the second connection member 200. The first connection member 100 is selectively connected to the second connection member 200 through the quick release mechanism 400. The quick release mechanism 400 is used to realize installation and disassembly between the first connection member 100 and the second connection member 200. It is easy to use, improves the efficiency of assembly and disassembly, and has strong versatility. It can match various types of first connection members 100 and second connection members 200.

[0057] Of course, the number of the quick release mechanism 400 can be one or more, and the multiple quick release mechanisms 400 are arranged on both sides of the first connecting member 100 along the second direction, or the multiple quick release mechanisms 400 are arranged on both sides of the first connecting member 100 along the third direction. The present embodiment does not limit the number of the quick release mechanisms 400, and can be adjusted according to actual production conditions. The present embodiment takes the number of two quick release mechanisms 400 as an example, and the two quick release mechanisms 400 can be approximately arranged at the diagonal positions of the first connecting member 100 to improve the connection stability between the first connecting member 100 and the second connecting member 200.

[0058] In the embodiments of the present application, Figure 1-Figure 2 As shown, a support member 104 is provided on a side of the first connecting member 100 away from the second connecting member 200 , and the support member 104 is used to support a workpiece to be processed.

[0059] The support member 104 may be a support block or a support column. The support member 104 may be a cylinder, a cuboid or other irregular structures. The support member 104 is used to provide a support position for the workpiece to be processed, facilitating subsequent operation and positioning of the workpiece to be processed.

[0060] Of course, the number of the support members 104 can be multiple, and the multiple support members 104 can be arranged on the first connecting member 100 in a regular or irregular shape such as an array or a ring, and the multiple support members 104 are used together to support the workpiece to be processed to improve the support stability of the workpiece to be processed. It can be understood that the height and shape of the multiple support members 104 can be the same or different, and the multiple support members 104 are adapted to the outer contour of the workpiece to be processed, and the height and shape of the support members 104 are adjusted according to the bottom shape of the workpiece to be processed.

[0061] In the embodiment of the present application, one of the sides of the first connecting member 100 and the workpiece to be processed that are close to each other is provided with a positioning pin 106, and the other is provided with a positioning groove (not shown in the figure). Specifically, the top of the first connecting member 100 is provided with a positioning pin 106, and the bottom of the workpiece to be processed is provided with a positioning groove, and the positioning pin 106 is at least partially penetrated through the positioning groove to achieve positioning between the workpiece to be processed and the first connecting member 100.

[0062] In the embodiment of the present application, a guide member 105 is provided on one side of the first connecting member 100 away from the second connecting member 200, and the guide member 105 is used to guide the workpiece to be processed. Under the guiding effect of the guide member 105, the smoothness of the workpiece to be processed entering the first connecting member 100 is improved.

[0063] Exemplarily, the guide member 105 has a guide bevel, which is inclined relative to the second direction and inclined downward toward the support member 104. When the workpiece to be processed contacts the guide bevel, the guide bevel guides the workpiece to be processed, allowing the workpiece to be processed to slide onto the support member 104 through the guide bevel.

[0064] Of course, there can be multiple guide members 105, and multiple guide members 105 are arranged around multiple support members 104. The accommodating space surrounded by multiple guide members 105 is slightly larger than the external dimensions of the workpiece to be processed. Multiple guide members 105 jointly guide the workpiece to be processed, thereby improving the convenience of installation of the workpiece to be processed.

[0065] It is understandable that the guide member 105 and the first connecting member 100 can be connected by welding or detachable connection. Specifically, the first connecting member 100 is provided with a first connecting hole, and the guide member 105 is provided with a second connecting hole corresponding to the first connecting hole. The connecting member is inserted through the first connecting hole and the second connecting hole for connection between the guide member 105 and the first connecting member 100. Among them, the connecting member can be a bolt, and the guide member 105 and the first connecting member 100 are connected by threaded connection, which is convenient for installation and disassembly between the guide member 105 and the first connecting member 100. At the same time, at least one of the first connecting hole and the second connecting hole is an oblong hole structure, and the connecting member can move along the first connecting hole and the second connecting hole to adjust the position of the guide member 105 relative to the first connecting member 100, so as to adapt to workpieces of different sizes to be processed and improve versatility.

[0066] In the embodiments of the present application, Figure 3 As shown, the connecting device also includes a positioning member 300, wherein the positioning member 300 may be an optional positioning pin, the first connecting member 100 is provided with a first positioning hole 103, the second connecting member 200 is provided with a second positioning hole 204 corresponding to the first positioning hole 103, and the positioning member 300 is passed through the first positioning hole 103 and the second positioning hole 204.

[0067] When the first connecting member 100 and the second connecting member 200 are installed, the positioning member 300 is used to achieve initial positioning of the first connecting member 100 and the second connecting member 200, thereby ensuring the accuracy of the installation of the two and improving the installation precision.

[0068] This embodiment also provides a quick release mechanism 400, such as Figure 3-Figure 4 As shown, the quick release mechanism 400 includes a fixing member 1 and a locking assembly 2, wherein the fixing member 1 is at least partially disposed in the first connecting member 100. The locking assembly 2 is disposed through the fixing member 1 and the second connecting member 200, and the locking assembly 2 is configured to be able to move and rotate relative to the fixing member 1 along the axial direction of the fixing member 1, so that the locking assembly 2 is selectively engaged with the second connecting member 200.

[0069] The fixing member 1 may be disposed only in the first connecting member 100, or a portion of the fixing member 1 may be disposed in the first connecting member 100 and another portion of the fixing member 1 may be disposed in the second connecting member 200. The fixing member 1 is disposed perpendicularly to the first connecting member 100, and the axial direction of the fixing member 1 is the first direction.

[0070] When the first connecting member 100 and the second connecting member 200 need to be installed, the locking assembly 2 is moved along the axial direction of the fixing member 1 and in the direction away from the fixing member 1, and then the locking assembly 2 is rotated relative to the fixing member 1 so that the locking assembly 2 is engaged with the second connecting member 200, thereby realizing the installation between the first connecting member 100 and the second connecting member 200; when the first connecting member 100 and the second connecting member 200 need to be disassembled, the locking assembly 2 is moved along the axial direction of the fixing member 1 and in the direction away from the fixing member 1, and the locking assembly 2 is rotated along the axial direction of the fixing member 1 so that the locking assembly 2 and the second connecting member 200 are disengaged, thereby releasing the lock between the locking assembly 2 and the second connecting member 200, and then the locking assembly 2 is moved along the axial direction of the fixing member 1 and in the direction close to the fixing member 1, thereby removing the entire quick release mechanism 400 from the first connecting member 100 and the second connecting member 200, thereby realizing the disassembly between the first connecting member 100 and the second connecting member 200.

[0071] The quick release mechanism 400 provided in this embodiment moves and rotates the locking assembly 2 relative to the fixing member 1 along the axial direction of the fixing member 1, so that the locking assembly 2 is selectively connected to the second connecting member 200 to switch between the locking mode and the unlocking mode, which is convenient for the installation and removal between the first connecting member 100 and the second connecting member 200. Compared with the prior art of using tools to remove screws, the operation is simple, the replacement time is saved, and the disassembly efficiency is improved. At the same time, the fixing member 1 and the locking assembly 2 have a simple structure, save space, reduce the risk of failure, and have good stability.

[0072] In the embodiments of the present application, Figure 4-Figure 5 As shown, a first mounting hole 101 is provided in the first connecting member 100 , and the fixing member 1 is provided in the first mounting hole 101 . The first mounting hole 101 is used for installing the fixing member 1 .

[0073] The first mounting hole 101 is one of a bar hole, an oblong hole, and an elliptical hole, and the cross section of the fixing member 1 is one of a bar, an oblong, and an elliptical shape.

[0074] That is, the outer contour of the fixing member 1 is adapted to the inner wall of the first mounting hole 101, and the distance between the outer wall of the fixing member 1 and the central axis of the locking assembly 2 is not exactly the same. When the locking assembly 2 rotates relative to the fixing member 1, the fixing member 1 will not rotate with the rotation of the locking assembly 2, thereby playing a limiting role.

[0075] In the embodiments of the present application, Figure 4-Figure 6 As shown, a limiting platform 102 is arranged in the first mounting hole 101 , a limiting groove 12 is arranged on the outer wall of the fixing member 1 , and the limiting platform 102 is arranged in the limiting groove 12 for limiting the position between the fixing member 1 and the first connecting member 100 .

[0076] By the mutual cooperation between the limit platform 102 and the limit groove 12, the limit between the fixing member 1 and the first connecting member 100 is achieved, thereby preventing the quick release mechanism 400 from being inserted into the first mounting hole 101 too deep or insufficiently along the first direction, thereby improving the positioning accuracy of the fixing member 1 relative to the first connecting member 100.

[0077] Specifically, the first mounting hole 101 includes a first through hole and a second through hole, the first through hole is connected to the second through hole, the first through hole is arranged at the end of the second through hole away from the second connector 200, the inner diameter of the first through hole is slightly larger than the inner diameter of the second through hole, so that the step formed between the first through hole and the second through hole is the limiting platform 102. The outer wall of the fixing member 1 is recessed in the direction away from the first connector 100 to form a limiting groove 12, and the limiting platform 102 is in contact with the side wall and the bottom wall of the limiting groove 12, and is used for limiting the fixing member 1 and the first connector 100. The limiting platform 102 supports the fixing member 1 on the top surface along the first direction, and plays a supporting role.

[0078] In addition, since the inner diameter of the first through hole is slightly larger than the inner diameter of the second through hole, even if the locking assembly 2 has a tendency to pull the fixing member 1 to move along the axial direction of the fixing member 1 and toward the second connecting member 200, the limiting platform 102 prevents the fixing member 1 from moving along with the movement of the locking assembly 2. However, when the quick release mechanism 400 is disassembled, when the locking assembly 2 is moved along the axial direction of the fixing member 1 and away from the second connecting member 200, the fixing member 1 can be lifted upward along the first direction, and the limiting platform 102 will not restrict the fixing member 1 from disengaging, so that the quick release mechanism 400 can be moved out of the first connecting member 100 as a whole.

[0079] In the embodiments of the present application, Figure 4 and Figure 6-Figure 7 As shown, the second connecting member 200 is provided with a second mounting hole 201 corresponding to the first mounting hole 101 , and the fixing member 1 is passed through the first mounting hole 101 and the second mounting hole 201 .

[0080] In this way, the length of the fixing member 1 along the first direction is greater than the depth of the first mounting hole 101 along the first direction, so that the fixing member 1 can extend into the second mounting hole 201 of the second connecting member 200. The fixing member 1 can achieve the function of intermediate connection between the first connecting member 100 and the second connecting member 200 to a certain extent, thereby improving the connection stability of the first connecting member 100 and the second connecting member 200 during installation.

[0081] The second mounting hole 201 is one of a bar hole, an oblong hole, and an elliptical hole.

[0082] That is, the outer contour of the fixing member 1 is adapted to the inner wall of the second mounting hole 201, and the distance between the outer wall of the fixing member 1 and the central axis of the locking assembly 2 is not exactly the same. When the locking assembly 2 rotates relative to the fixing member 1, the fixing member 1 will not rotate with the rotation of the locking assembly 2, thereby playing a limiting role.

[0083] In the embodiments of the present application, Figure 4 , Figure 6 and Figure 8 As shown, the locking assembly 2 includes a movable shaft 21, and the fixing member 1 is provided with an axial hole along the axial direction of the fixing member 1. The movable shaft 21 passes through the axial hole and the second mounting hole 201 of the second connecting member 200 and slidably cooperates with the axial hole.

[0084] Specifically, the movable shaft 21 is a cylindrical structure, and the shaft hole is a circular hole structure. The inner diameter of the shaft hole is slightly larger than the movable shaft 21. The movable shaft 21 and the shaft hole are clearance-matched. The movable shaft 21 can move up and down along the first direction relative to the shaft hole. The movable shaft 21 can also rotate freely relative to the shaft hole, so that the quick release mechanism 400 can switch between the locking mode and the disassembly mode.

[0085] In an embodiment of the present application, the locking assembly 2 also includes a locking block 22, which is connected to one end of the movable shaft 21 away from the movable shaft 21, wherein the movable shaft 21 is configured to be able to move along the shaft hole and away from the fixing member 1, and to be able to rotate relative to the shaft hole, so that the locking block 22 can be selectively engaged with the second connecting member 200.

[0086] Specifically, the locking block 22 is one of a bar-shaped hole, an oblong hole, and an elliptical hole. That is, the outer contour of the locking block 22 is adapted to the inner wall of the second mounting hole 201, and the distance between the outer wall of the locking block 22 and the central axis of the locking assembly 2 is not completely the same. When the movable shaft 21 rotates relative to the shaft hole, the locking block 22 will not rotate in the second mounting hole 201 along with the rotation of the movable shaft 21, and plays a role of limiting.

[0087] In the embodiments of the present application, Figure 9-11 As shown, a locking groove 202 and a disassembly groove 203 are provided on the side of the second connecting member 200 away from the first connecting member 100. The locking groove 202 and the disassembly groove 203 are interconnected and arranged at an angle. The locking component 2 of the quick release mechanism 400 is configured to be selectively arranged in the locking groove 202 or the disassembly groove 203.

[0088] When the locking block 22 of the locking assembly 2 is set in the disassembly groove 203, the locking block 22 and the second connecting member 200 are in an unlocked state, the quick release mechanism 400 and the first connecting member 100 and the second connecting member 200 are released from the limit, and the quick release mechanism 400 can be removed from the first connecting member 100 and the second connecting member 200 to achieve the disassembly between the first connecting member 100 and the second connecting member 200; when the locking block 22 of the locking assembly 2 is set in the locking groove 202, the locking block 22 and the second connecting member 200 are in a locked state, so that the first connecting member 100 is connected to the second connecting member 200 through the quick release mechanism 400, and the installation between the first connecting member 100 and the second connecting member 200 is achieved.

[0089] Specifically, the disassembly groove 203 and the second mounting hole 201 are arranged correspondingly, and the disassembly groove 203 and the second mounting hole 201 are arranged coaxially. The size and shape of the disassembly groove 203 and the second mounting hole 201 are similar. After the locking block 22 is rotated to the disassembly groove 203, when the movable shaft 21 is pulled upward along the first direction and in the direction close to the first connecting member 100, the locking block 22 can directly enter the second mounting hole 201 through the disassembly groove 203, so as to facilitate the disassembly of the quick release mechanism 400.

[0090] Specifically, the angle between the locking groove 202 and the disassembly groove 203 can be an acute angle, a right angle or an obtuse angle. For example, the angle between the locking groove 202 and the disassembly groove 203 is 90°, and the central axis of the locking groove 202 is perpendicular to the central axis of the disassembly groove 203. The operator only needs to rotate the movable shaft 21 90° each time to switch between the locking mode and the disassembly mode.

[0091] It is understandable that the shape of the locking groove 202 is one of a bar hole, an oblong hole, and an elliptical hole, that is, the outer contour of the locking block 22 is matched with the inner wall of the locking groove 202, which plays a role of limiting.

[0092] In the embodiment of the present application, the outer diameter of the locking block 22 is greater than the inner diameter of the shaft hole.

[0093] In this way, when the movable shaft 21 drives the locking block 22 to move along the first direction and toward the first connecting member 100, the movable shaft 21 can slide in the shaft hole, but because the outer diameter of the locking block 22 is larger than the inner diameter of the shaft hole, the locking block 22 cannot pass through the shaft hole, and the locking block 22 will contact the end surface of the fixing member 1 facing the locking block 22, playing a role of limiting. At the same time, as the movable shaft 21 drives the locking block 22 to continue to move, the locking block 22 drives the fixing member 1 to move, and the locking block 22 plays a role of supporting the fixing member 1, and drives the fixing member 1 to disengage from the first mounting hole 101 of the first connecting member 100.

[0094] In the embodiments of the present application, Figure 4 , Figure 6 and Figure 8 As shown, the locking assembly 2 further includes a holding portion 23 , which is disposed at an end of the locking block 22 away from the movable shaft 21 and located outside the second connecting member 200 .

[0095] That is, the holding portion 23 is a protruding portion of the locking block 22, and the holding portion 23 is used for the operator to hold, so that the operator can pull or rotate the movable shaft 21, thereby improving the convenience of operation. Of course, the size of the holding portion 23 can be smaller than the size of the locking block 22, which further facilitates the operator to hold, and can also ensure the stability of the locking between the locking block 22 and the locking groove 202.

[0096] It is understandable that the movable shaft 21, the locking block 22 and the holding portion 23 can be a split structure, and the movable shaft 21 and the locking block 22, and the locking block 22 and the holding portion 23 can be connected by bolts, which is convenient for partial replacement and maintenance. The movable shaft 21, the locking block 22 and the holding portion 23 can also be an integrated structure to reduce the parts assembly process and save production costs.

[0097] At least one of the locking block 22 and the holding portion 23 is provided with a reserved hole 231 .

[0098] For example, the operator can insert the operating tool into the reserved hole 231 and control the locking assembly 2 by controlling the operating tool; or after the locking block 22 of the locking assembly 2 rotates to the locking groove 202, the pin is inserted into the reserved hole 231 and connected to other fixed positions to further improve the locking stability of the locking block 22. Of course, the reserved hole 231 includes but is not limited to the above two situations, and can also be used for positioning during storage, transportation, etc. of the quick release mechanism 400, or for weight reduction effects, and can be adjusted according to actual production conditions.

[0099] In the embodiments of the present application, Figure 4 , Figure 6 and Figure 8 As shown, the locking assembly 2 further includes a limiting member 24 , which is disposed at one end of the movable shaft 21 away from the locking block 22 and is used for limiting the position between the locking assembly 2 and the fixing member 1 .

[0100] Specifically, the limit member 24 is arranged at one end of the movable shaft 21 away from the locking block 22, that is, the limit member 24 is arranged at the top of the movable shaft 21 along the first direction. When the movable shaft 21 slides along the first direction relative to the shaft hole toward the direction close to the second connecting member 200, the limit member 24 can be used to prevent the movable shaft 21 from completely entering the shaft hole and directly sliding out of the shaft hole.

[0101] In the embodiment of the present application, a groove 11 is provided on a side of the fixing member 1 facing the limiting member 24 , and the groove 11 is used to avoid the limiting member 24 .

[0102] In this way, the depth of the groove 11 along the first direction provides space for the limiter 24 to move along the movable shaft 21 along the first direction, thereby increasing the movable range of the movable shaft 21 along the first direction, thereby improving the convenience of using the quick release mechanism 400.

[0103] In the embodiment of the present application, the quick release mechanism 400 also includes an elastic member 25, wherein the elastic member 25 can be a cylindrical spring, a torsion spring, etc. The elastic member 25 is sleeved on the outside of the locking assembly 2 and is arranged between the locking assembly 2 and the fixing member 1, and is used for resetting the locking assembly 2.

[0104] Specifically, a receiving groove is provided in the fixing member 1, the receiving groove and the shaft hole are connected, the movable shaft 21 is passed through the receiving groove and the shaft hole, the receiving groove is used to receive the elastic member 25, the diameter of the receiving groove is larger than the diameter of the shaft hole, so that a limiting step is formed between the receiving groove and the shaft hole, and the limiting step is used to limit the elastic member 25.

[0105] When the movable shaft 21 moves along the first direction and in the direction approaching the second connecting member 200, the two ends of the elastic member 25 abut against the limiting steps of the limiting member 24 and the fixing member 1, and the elastic member 25 is gradually compressed. If the locking block 22 rotates to the locking groove 202, the elastic force of the elastic member 25 is used to increase the locking effect between the locking block 22 and the locking groove 202; if the locking block 22 rotates to the disassembly groove 203, under the restoring force of the elastic member 25 itself, the movable shaft 21 can drive the locking block 22 to reset.

[0106] The working process of the quick release mechanism 400 provided in this embodiment is as follows:

[0107] When the first connecting member 100 and the second connecting member 200 need to be installed, the locking block 22 of the quick release mechanism 400 is rotated to be consistent with the direction of the disassembly groove 203, and the fixing member 1 of the quick release mechanism 400 is placed in the first installation hole 101 of the first connecting member 100. Then, the operator pulls the locking block 22 and the movable shaft 21 along the first direction and moves toward the second connecting member 200 through the holding portion 23. After the locking block 22 extends to the second installation hole 201 of the second connecting member 200, the locking block 22 is rotated 90° so that the locking block 22 is snapped into the locking groove 202, and the first connecting member 100 and the second connecting member 200 are installed, and then the fixture replacement process is completed. Then, the workpiece to be processed is moved to the support member 104 of the first connecting member 100 under the guidance of the guide member 105, which is convenient for the subsequent positioning and operation of the workpiece to be processed;

[0108] When the first connecting member 100 and the second connecting member 200 need to be disassembled, the operator pulls the locking block 22 and the movable shaft 21 along the first direction and in the direction close to the second connecting member 200 through the holding portion 23. After the locking block 22 extends to the second mounting hole 201 of the second connecting member 200, the locking block 22 is rotated 90° so that the locking block 22 is rotated into the disassembly groove 203, and then the entire quick-release mechanism 400 is lifted along the first direction and in the direction close to the first connecting member 100, so that the quick-release mechanism 400 is separated from the first connecting member 100 and the second connecting member 200, thereby realizing the disassembly of the first connecting member 100 and the second connecting member 200.
