DETAILED DESCRIPTION

[0028] The embodiments of the present application will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0029] As shown in Figs. 1 to 4 , the present application provides a clamping device for arc-shaped plates, comprising:

[0030] a base 100;

[0031] a rotary seat 102 rotatably mounted on the base 100, a sliding groove 104 is formed on the rotary seat 102 along the circumference of the rotary seat 102, and an abutting block 106 is arranged in the sliding groove 104;

[0032] The fixed seat 108 is installed on the base 100, and along the circumference of the fixed seat 108, a mounting groove 110 for fixing the arc-shaped plate is arranged on the fixed seat 108, and a processing hole 112 is arranged on the groove side wall of the mounting groove 110, and along the radial direction of the fixed seat 108, a guide groove 114 for guiding the abutting block 106 is arranged on the fixed seat 108.

[0033] The rotating seat 102 is adapted to switch between a first position and a second position, in the first position, the sliding groove 104 is adapted to drive the abutting block 106 to abut against the arc-shaped plate, and in the second position, the sliding groove 104 is adapted to drive the abutting block 106 to move away from the arc-shaped plate.

[0034] According to the clamping device for the arc-shaped plate provided in the embodiment of the utility model, through the design of the rotating seat 102 and the fixed seat 108, and the cooperation of the sliding groove 104, the abutting block 106 and the guide groove 114, the clamping device can realize high-precision clamping of the arc-shaped plate. This not only improves the stability in the processing process, but also ensures the processing precision. Since the rotating seat 102 can rotate, and the sliding groove 104 and the abutting block 106 are arranged to allow a certain degree of adjustment, the clamping device can adapt to arc-shaped plates of different shapes and sizes, greatly enhancing the versatility and practicality of the device. When the rotating seat 102 is in the first position, the sliding groove 104 drives the abutting block 106 to abut against the arc-shaped plate, at this time, the arc-shaped plate can be processed, such as drilling, avoiding the deformation of the arc-shaped plate, which not only reduces the operation difficulty, but also improves the work efficiency. Since the clamping device can stably fix the arc-shaped plate, the processing efficiency and processing quality can be greatly improved during subsequent processing operations.

[0035] Please continue to see Figs. 1 to 4 The embodiment of the utility model provides a device specially used for clamping arc-shaped plates, which is exquisite in structure and strong in functionality.

[0036] The base 100 serves as the basic support structure of the entire clamping device, and the base 100 provides a stable mounting platform to ensure that other components can be stably installed and function.

[0037] The rotating seat 102 is rotatably installed on the base 100, which means that the user can adjust the position of the rotating seat 102 as needed. Along the circumference of the rotating seat 102 (i.e. the circumferential direction around the center of the rotating seat 102), a sliding groove 104 is arranged. The sliding groove 104 is provided with an abutting block 106, and the abutting block 106 can slide in the sliding groove 104, thereby realizing clamping or releasing operation of the arc-shaped plate.

[0038] The fixed seat 108 is also mounted on the base 100, but unlike the rotating seat 102, the position of the fixed seat 108 is fixed. On the circumference of the fixed seat 108, an installation groove 110 for fixing the arc-shaped plate is designed. The shape and size of the installation groove 110 match the arc-shaped plate to be processed, ensuring that the plate can be stably placed therein. In addition, a processing hole 112 is also provided on the groove side wall of the installation groove 110, which can be used for subsequent processing operations (such as drilling, cutting, etc.). In order to guide the movement of the abutting block 106, a guide groove 114 extending radially on the fixed seat 108 is also provided, which cooperates with the sliding groove 104 on the rotating seat 102 and the abutting block 106, ensuring that the abutting block 106 can be accurately moved to the required position.

[0039] The rotating seat 102 can be switched between the first position and the second position. In the first position, the sliding groove 104 drives the abutting block 106 to move to the position in contact with the arc-shaped plate, and further slides to abut the plate. In the second position, the sliding groove 104 drives the abutting block 106 away from the arc-shaped plate, thereby releasing the plate.

[0040] According to an embodiment of the present application, the abutting block 106 comprises:

[0041] The connecting portion 116 is slidably connected to the sliding groove 104;

[0042] The abutting portion 118 is connected to the connecting portion 116, and the abutting portion 118 is provided with the guide groove 114.

[0043] In the embodiment of the present application, the abutting block 106 is further refined into the connecting portion 116 and the abutting portion 118. This design not only enhances the functionality of the abutting block 106, but also improves the stability and reliability of the abutting block 106 in the clamping device.

[0044] The connecting portion 116 is a connecting structure between the abutting block 106 and the sliding groove 104, and the connecting portion 116 can be slidably connected to the sliding groove 104, which means that the shape and size of the connecting portion 116 and the sliding groove 104 must match each other to ensure that the connecting portion 116 can smoothly slide in the sliding groove 104.

[0045] The connecting portion 116 can be made of wear-resistant and high-strength materials to withstand the friction and force generated during clamping and releasing the arc-shaped plate.

[0046] Through the sliding connection of the connecting portion 116 and the sliding groove 104, the user can conveniently adjust the position of the abutting block 106, thereby realizing the clamping or releasing of the arc-shaped plate.

[0047] The abutting portion 118 is the part of the abutting block 106 that directly abuts against the curved plate, and is connected to the connecting portion 116 and extends a sufficient length and width to ensure that it can fully cover and abut against the surface of the curved plate.

[0048] The shape and size of the abutting portion 118 can be customized according to the specific shape and size of the curved plate to achieve the best clamping effect.

[0049] In this embodiment, the abutting portion 118 is also provided with a portion corresponding to the guide groove 114. This means that when the rotating seat 102 is in the first position, the abutting portion 118 will slide along the guide groove 114 until it is tightly abutted against the curved plate. This design not only improves the accuracy of clamping, but also ensures the stability of the abutting block 106 during clamping.

[0050] The abutting portion 118 can also be made of wear-resistant and high-strength materials to withstand the pressure and friction generated during clamping.

[0051] With this design, the abutting block 106 not only can achieve stable clamping of the curved plate, but also can be accurately adjusted as needed.

[0052] According to an embodiment of the present application, the end of the abutting portion 118 away from the connecting portion 116 is provided with a recessed portion 119, and the recessed portion 119 is correspondingly arranged with the machining hole 112.

[0053] In the embodiment of the present application, the recessed portion 119 is correspondingly arranged with the machining hole 112, which means that the position, shape and size of the recessed portion 119 are designed according to the position, shape and size of the machining hole 112 to ensure that they can match or correspond to each other.

[0054] By providing the recessed portion 119 at the end of the abutting portion 118 away from the connecting portion 116, when drilling or other operations are performed on the curved plate, the drill bit of the machining equipment will not damage the abutting portion 118, ensuring the service life of the abutting block 106.

[0055] According to an embodiment of the present application, the guide groove 114 is provided with an avoidance groove 120 at a position corresponding to the machining hole 112.

[0056] In the embodiment of the present application, the avoidance groove 120 is provided at a position corresponding to the machining hole 112. This design means that a slot is hollowed out or cut at a certain position of the guide groove 114, and the position of this slot corresponds to the position of the machining hole 112. The shape, size and depth of the avoidance groove 120 are designed according to actual application requirements to ensure that it neither affects the normal use of the guide groove 114 nor meets the specific functional requirements.

[0057] By opening the avoiding groove 120 in the side wall of the guide groove 114, when drilling holes or other processing is performed on the arc-shaped plate, even if a through hole is processed on the arc-shaped plate, the drill bit will not cause damage to the abutting block 106.

[0058] According to an embodiment of the present application, one end of the sliding groove 104 is provided with a limiting part, and in the first position, the connecting part 116 is adapted to realize limiting with the sliding groove 104 through the limiting part.

[0059] In the embodiment of the present application, the limiting part is arranged at one end of the sliding groove 104, and is used to limit the sliding range of the connecting part 116. The shape and size of the limiting part are carefully designed to ensure that the connecting part 116 can be stably stopped at the predetermined position. The limiting part can adopt a protrusion, a groove or other shapes to realize close cooperation with the connecting part 116.

[0060] In the first position, the connecting part 116 realizes limiting with the sliding groove 104 through the limiting part. This means that when the connecting part 116 slides to the limiting part of the sliding groove 104, the connecting part 116 will not continue to slide, but will be stably fixed there by the limiting part. This design ensures the stability and reliability of the connecting part 116 in a specific position.

[0061] Through the arrangement of the limiting part, the sliding range of the connecting part 116 in the sliding groove 104 is limited, thereby improving the stability of the whole structure. This helps to prevent the connecting part 116 from sliding uncontrollably, causing the structure to loosen or be damaged. The existence of the limiting part ensures that the connecting part 116 can be stably stopped at the predetermined position. This reliability is particularly important for application scenarios that require precise control of the position of the connecting part 116. The combination of the sliding groove 104 and the limiting part can simplify the operation process. The user only needs to slide the connecting part 116 into the sliding groove 104 and let it automatically slide to the limiting part to realize stable positioning. This reduces the steps of needing to fix or adjust the connecting part 116 additionally.

[0062] According to an embodiment of the present application, along the circumference of the fixing seat 108, a notch part 122 is opened on the fixing seat 108, and the notch part 122 is recessed towards the center direction of the fixing seat 108.

[0063] In the embodiment of the present application, a notch part 122 is opened around the edge of the fixing seat 108, that is, on the circumference. This notch is not simply cutting or removing a part of material, but is formed in a way of recessing towards the center direction of the fixing seat 108.

[0064] By removing a portion of the material, the overall weight of the fixing seat 108 can be reduced. In addition, by providing the notch portion 122, it is more convenient to install the arc-shaped plate on the fixing seat 108, and the notch portion 122 provides more space for easy access or operation.

[0065] According to an embodiment of the present application, a first through hole 124 is formed in the base 100, a second through hole 126 is formed in the fixing seat 108, and a first boss and a second boss are provided on the rotating seat 102, the first boss is inserted into the first through hole 124, and the second boss is inserted into the second through hole 126.

[0066] In the embodiment of the present application, a first through hole 124 is formed in the base 100, the first through hole 124 is used to install the first boss on the rotating seat 102. At the same time, a second through hole 126 is also formed in the fixing seat 108, and the second through hole 126 is used to install the second boss on the rotating seat 102.

[0067] Through the insertion connection of the first boss and the first through hole 124, and the second boss and the second through hole 126, the close fit and stable connection between the components of the device are achieved. This structure design makes the device stable when bearing external force or load, and is not easy to loosen or deform. The rotating seat 102 can rotate relative to the base 100 and the fixing seat 108, which meets the application scenarios that require rotation function. Due to the cooperation design of the boss and the through hole, the rotating movement is stable while also having a certain flexibility.

[0068] According to an embodiment of the present application, the end face of the second boss is provided with a rotation stopping hole 128, and a rotating handle is detachably inserted into the rotation stopping hole 128.

[0069] In the embodiment of the present application, a rotation stopping hole 128 is added to the second boss of the rotating seat 102, and a detachable rotating handle is designed to cooperate with it. The design of the rotation stopping hole 128 allows the rotating handle to be stably inserted and fixed on the second boss without loosening or falling off. The shape and size of the rotation stopping hole 128 are matched with the rotating handle to ensure the close fit between them.

[0070] The rotating handle is a detachable component for manually rotating the rotating seat 102. The shape and size of the rotating handle are designed to be easy to hold and operate, usually with anti-slip texture or handle to increase friction. The insertion end of the rotating handle is matched with the rotation stopping hole 128, and can be firmly inserted and fixed in the rotation stopping hole 128.

[0071] By setting the rotation stopping hole 128 on the second boss of the rotating seat 102 and equipping with a detachable rotating handle, the user can more conveniently manually rotate the rotating seat 102. The holding and operation of the rotating handle are more comfortable and stable, reducing the operation difficulty and fatigue.

[0072] It can be understood that by setting the rotating handle, the rotating seat 102 can be flexibly switched between the first position and the second position, thereby realizing the clamping or loosening of the arc-shaped plate.

[0073] According to an embodiment of the present application, the base 100 is provided with a first positioning part, and the fixing seat 108 is provided with a second positioning part matched with the first positioning part.

[0074] In the embodiment of the present application, the first positioning part is a specific structure on the base 100, which is used for positioning and matching with the second positioning part on the fixing seat 108. The shape, size and position of the first positioning part are carefully designed to ensure accurate matching with the second positioning part.

[0075] Similarly, the second positioning part is a specific structure on the fixing seat 108, corresponding to the first positioning part on the base 100. The shape, size and position of the second positioning part are matched with the first positioning part to realize accurate positioning of the two.

[0076] When the fixing seat 108 is installed on the base 100, the first positioning part and the second positioning part will contact and tightly match each other. This matching can be plug-in, clamping, threaded connection or other forms of connection, depending on the design requirements. Through the matching of the first positioning part and the second positioning part, the accurate position of the fixing seat 108 on the base 100 can be ensured, so as to realize high-precision positioning of the whole device.

[0077] By setting the first positioning part and the second positioning part on the base 100 and the fixing seat 108 respectively and realizing the positioning and matching of the two, the positioning accuracy of the whole device can be significantly improved. The matching of the first positioning part and the second positioning part not only improves the positioning accuracy, but also enhances the structural stability of the whole device. Through this matching, the firm fixation of the fixing seat 108 on the base 100 can be ensured, preventing loosening or displacement caused by vibration, impact and other factors.

[0078] According to an embodiment of the present application, the side of the base 100 away from the first positioning part is provided with a clamping part for clamping.

[0079] In the embodiments of the utility model, the clamping part is arranged on the side of the base 100 away from the first positioning part, that is, the other side opposite to the first positioning part. The design of the clamping part aims to provide a reliable connection interface for fixing the device on other components, equipment or workbench. The clamping part can have various forms, such as clamping grooves, threaded holes, mounting plates, etc., depending on the application scenario and connection requirements of the device.

[0080] By adding the clamping part on the base 100, the device can be more conveniently connected and fixed with the machine tool and the clamping table.
