Abstract
Description
Technical Field
[0001] This application relates to the field of clamping technology, for example to a clamping device for a development board. Background Technology
[0002] A related technology (publication number: CN218698059U) discloses a limiting fixture for development board production, including a main body mechanism, a clamping and flipping mechanism, and an adjustment mechanism. The main body mechanism includes a device body, a placement groove, a slide groove, and support feet. The clamping and flipping mechanism includes a fixed plate, a drive motor, a rotating shaft, a first clamping plate, a connecting plate, an electric push rod, a push rod, a rubber clamping plate, a rotating plate, a rotating rod, and a second clamping plate. The adjustment mechanism includes a transmission motor, a limiting plate, a double-sided threaded rod, a movable disc, a positioning nut, and a slider.
[0003] In implementing the above embodiments, at least the following problems were found in the related technology:
[0004] This development board production clamp has clamping and flipping mechanisms on both sides to hold and fix the development board and to rotate it. An adjustment mechanism changes the spacing between the two clamping and flipping mechanisms to accommodate development boards of different sizes. However, during the rotation of the development board, only one clamping and flipping mechanism applies a rotational force to one side of the board. Therefore, due to the inertia of the other clamping and flipping mechanism, the other side of the development board will experience a force in the opposite direction, making the development board susceptible to damage due to twisting. Furthermore, since the other clamping and flipping mechanism can rotate freely, manual adjustment is required to align the two clamping and flipping mechanisms before clamping the development board to ensure proper clamping and fixation.

[0016] Optionally, it further includes: a finger clamp, respectively installed on each movable end of the thumb cylinder on both sides, and the two finger clamps installed on the two movable ends of the same thumb cylinder are distributed opposite to each other.
[0017] The development board clamping device provided in this disclosure can achieve the following technical effects:
[0018] This disclosure provides a clamping device for a development board, comprising a support plate, a bending plate, a hollow shaft, a splined sleeve, a splined shaft, a rotating shaft, a thumb cylinder, a transmission component, a first driving component, and a second driving component. The support plate abuts against the ground or a tabletop, thereby supporting the entire device. The bending plate is located above the support plate and along its length on both sides of the support plate, supporting the rotatable hollow shaft and the rotating shaft respectively. The hollow shaft is rotatably mounted on the two bending plates along the length of the support plate. The axes of the two hollow shafts coincide, allowing them to rotate relative to the two bending plates. The splined sleeves are installed inside the hollow shafts and rotate synchronously with them. The splined shaft passes through the splined sleeves, allowing the sleeves to slide relative to the shaft, which in turn drives the sleeves to rotate. The rotating shaft is rotatably mounted on the two bending plates along the length of the support plate and is located above the hollow shafts. The axes of the two rotating shafts coincide, allowing them to rotate relative to the two bending plates. Thumb cylinders are mounted on opposite ends of the rotating shafts, clamping the two sides of the development plate. Transmission components are installed between the other ends of the rotating shafts and the outer walls of the hollow shafts, transmitting driving force to cause the rotating shafts to rotate along with the hollow shafts. A first drive component is installed between the support plate and the two bending plates, providing driving force to change the distance between the bending plates. A second drive component is installed between the first drive component and the splined shaft, providing driving force to drive the splined shaft to rotate.
[0019] During use, controlling the two thumb cylinders clamps and secures the development board from both sides. Controlling the second drive unit rotates the spline shaft, which in turn rotates the two spline sleeves, which in turn rotate the two hollow shafts. Through the two transmission components, the two rotating shafts rotate, ultimately causing the two thumb cylinders to rotate synchronously. This allows for simultaneous application of a flipping force to both sides of the development board, preventing damage from twisting. Furthermore, since the thumb cylinders are always aligned, it facilitates clamping and securing the development board. Controlling the first drive unit adjusts the spacing between the two bending plates, ultimately changing the spacing between the thumb cylinders, thus adapting to development boards of different sizes.

[0036] Combination Figures 1 to 4 As shown, this embodiment of the present disclosure provides a clamping device for a development board, including a support plate 10, a bending plate 20, a hollow shaft 30, a spline sleeve 40, a spline shaft 50, a rotating shaft 60, a thumb cylinder 70, a transmission component 80, a first driving component 90, and a second driving component 100. The support plate 10 is used to abut against the ground or a tabletop, thereby supporting the entire device. The bending plate 20 is located above the support plate 10 and along the length of the support plate 10, located on both sides of the support plate 10. The two bending plates 20 are respectively used to support and mount the rotatable hollow shaft 30 and the rotating shaft 60. The hollow shaft 30 is rotatably mounted on the two bending plates 20 along the length of the support plate 10. The axes of the two hollow shafts 30 coincide, and they can rotate relative to the two bending plates 20 respectively. The spline sleeve 40 is respectively installed inside the two hollow shafts 30 and rotates synchronously with the two hollow shafts 30. Splined shaft 50 passes through splined sleeves 40 on both sides, and both splined sleeves 40 can slide relative to splined shaft 50. Splined shaft 50 can drive the two splined sleeves 40 to rotate. Rotary shafts 60 are rotatably mounted on the two bending plates 20 along the length of support plate 10, and are located above the two hollow shafts 30. The axes of the two rotating shafts 60 coincide and can rotate relative to the two bending plates 20 respectively. Thumb cylinders 70 are respectively mounted on opposite ends of the two rotating shafts 60 and are used to clamp the two sides of the development plate. Transmission components 80 are respectively mounted between the other end of the two rotating shafts 60 and the outer wall of the two hollow shafts 30. The two transmission components 80 are used to transmit driving force so that the two rotating shafts 60 rotate with the rotation of the two hollow shafts 30. The first driving component 90 is mounted between support plate 10 and two bending plates 20 to provide driving force to change the distance between the two bending plates 20. The second drive component 100 is installed between the first drive component 90 and the spline shaft 50 to provide driving force to drive the spline shaft 50 to rotate.
[0037] This disclosure provides a clamping device for a development board. By controlling the operation of two thumb cylinders 70, the development board can be clamped and fixed on both sides. By controlling the operation of the second drive member 100, the spline shaft 50 can be rotated. This, in turn, drives the two spline sleeves 40 to rotate, and then drives the two hollow shafts 30 to rotate. Through the two transmission members 80, the two rotating shafts 60 can be driven to rotate, and finally drive the two thumb cylinders 70 to rotate synchronously. A flipping force can be applied to both sides of the development board at the same time, thereby avoiding damage to the development board due to twisting. At the same time, since the two thumb cylinders 70 are always directly opposite each other, it is convenient to clamp and fix the development board. By controlling the operation of the first drive member 90, the distance between the two bending plates 20 can be adjusted, and the distance between the two thumb cylinders 70 can be changed, thereby making it suitable for development boards of different sizes.
[0038] Optionally, combined Figure 1 and Figure 4 As shown, the transmission component 80 includes a driving gear 81, a driven gear 82, and a synchronous toothed belt 83. The driving gears 81 are respectively mounted on the outer walls of the hollow shafts 30 on both sides and rotate under the drive of the hollow shafts 30. The driven gears 82 are respectively mounted on the other ends of the rotating shafts 60 on both sides and are used to drive the rotating shafts 60 to rotate. The synchronous toothed belts 83 are respectively fitted onto the driving gears 81 on both sides and the driven gears 82 on both sides, and are used to transmit driving force. The diameter of the driving gears 81 on both sides is smaller than the diameter of the driven gears 82 on both sides.
[0039] In this embodiment, when the two rotating shafts 60 rotate, they drive the two driving gears 81 to rotate. The two synchronous toothed belts 83 drive the two driven gears 82 to rotate, which in turn drives the two rotating shafts 60 to rotate. Furthermore, the design of having a smaller diameter for the driving gears 81 than for the driven gears 82 reduces the rotational speed.
[0040] Optionally, combined Figure 1 and Figure 4As shown, the first driving component 90 includes a guide rail 91, a slider 92, a lead screw nut 93, and a double-acting lead screw 94. The guide rail 91 is mounted on the top surface of the support plate 10 along its length, supporting the slidable slider 92. The slider 92 is slidably mounted on the guide rail 91, located on both sides of the guide rail 91 along its length. Two bent plates 20 are respectively mounted on the two sliders 92. The two sliders 92 and the guide rail 91 together provide guidance and support, allowing the bent plates 20 to move along the length of the support plate 10. The lead screw nut 93 is mounted on the two bent plates 20 along the length of the support plate 10, located below the two hollow shafts 30, and is used to drive the two bent plates 20 to move. The double-acting lead screw 94 passes through the two lead screw nuts 93, collectively converting rotational motion into linear motion. The double-acting lead screw 94 can be rotated in a controlled manner to change the distance between the two bent plates 20.
[0041] In this embodiment, when the bidirectional lead screw 94 rotates, under the guiding and supporting action of the guide rail 91 and the two side sliders 92, the two side lead screws can be driven by the nuts 93 to move the two side bending plates 20 in opposite directions, ultimately realizing the spacing adjustment function of the two side thumb cylinders 70.
[0042] Optionally, combined Figure 1 and Figure 4 As shown, the first drive component 90 also includes a lead screw support 95. The lead screw supports 95 are respectively fitted onto both ends of the bidirectional lead screw 94 and are both mounted on the top surface of the support plate 10.
[0043] In this embodiment of the disclosure, the lead screw support 95 is used to support and install the rotatable bidirectional lead screw 94 in order to improve the rotation accuracy of the bidirectional lead screw 94.
[0044] Optionally, combined Figure 1 and Figure 4 As shown, the first driving component 90 also includes a motor base 96, a first motor 97, and a first coupling 98.

[0047] In this embodiment, the second motor 101 is controlled to work, and through the second coupling 102, the spline shaft 50 can be driven to rotate, ultimately realizing the automatic flipping function of the thumb cylinders 70 on both sides.
[0048] Optionally, combined Figure 1 and Figure 2 As shown, it also includes a first bearing housing 110 and a first bearing 120. The first bearing housing 110 is respectively installed on the two side bending plates 20 and respectively sleeved on the two side hollow shafts 30.
