Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a synchronous clamp capable of self-adjustment. Background Art

[0002] In the field of industrial product processing, various workpieces need to be clamped by special fixtures during processing to stabilize the workpieces and ensure processing accuracy. The common clamping method of these existing fixtures is the downward pressure type, which presses the workpiece on the workbench through a pressing mechanism. For fixtures with multiple pressing mechanisms, each pressing mechanism has an independent drive system, which will result in a large number of drive systems and increase manufacturing costs. However, if all pressing mechanisms use the same drive system, due to the errors of the workpiece itself and the errors of the pressing mechanism itself, there will be a situation where some pressing mechanisms have already pressed the workpiece, while other pressing mechanisms have not yet been pressed into place, which makes it impossible to stably clamp the workpiece.

[0025] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0026] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0027] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0028] The embodiment of the present invention provides a synchronous clamp capable of adaptive adjustment, such as Figure 1-4As shown, the apparatus comprises a workbench 100, a plurality of pressing members 200, a connecting member 300, and a driving rod 400. The workbench 100 is used to place a workpiece 10, which can be a substrate. The workpiece 10 is placed on the top surface of the workbench 100. The pressing members 200 are arranged on the workbench 100. The connecting member 300 is located below the workbench 100 and is connected to all the pressing members 200. When the connecting member 300 moves downward, it drives all the pressing members 200 downward, thereby driving all the pressing members 200 downward to compress the workpiece 10. The top surface of the connecting member 300 is provided with a ball-notch groove 301, and the bottom of the ball-notch groove 301 is provided with a through-hole 302 that penetrates the connecting member 300. The driving rod 400 is passed through the through-hole 302 and can move along the through-hole 302. The upper end of the driving rod 400 is provided with a ball-notch block 410 that is adapted to the ball-notch groove 301. The ball-notch block 410 is embedded in the ball-notch groove 301 and can rotate in the ball-notch groove 301. The lower end of the driving rod 400 is used to be connected to the drive system to drive the connecting member 300 to move downward.

[0029] In this embodiment, the drive rod 400 is connected to the drive system. When the drive system drives the connecting member 300 downward, it also drives all the pressing members 200 downward accordingly. Therefore, all the pressing members 200 are driven by a single drive system and can move synchronously. When some pressing members 200 are already pressing the workpiece 10 while others are not, the spherical segment block 410 cooperates with the spherical segment groove 301 to allow the connecting member 300 to deflect axially relative to the drive rod 400. The pressing members 200 that are already pressing the workpiece 10 cannot be pressed further downward, while the pressing members 200 that are not pressing the workpiece 10 can continue to press downward. The connecting member 300 adaptively deflects toward the pressing members 200 that are not pressing the workpiece 10, allowing the pressing members 200 that are not pressing the workpiece 10 to press further downward until they are pressed. This ensures that each pressing member 200 can press the workpiece 10 tightly, thereby stably clamping the workpiece 10 while using the same drive system.

[0030] In some embodiments, a guide base 500 is further provided below the workbench 100. The guide base 500 is provided with a downwardly extending guide groove 510. The connector 300 is inserted into and slides along the guide groove 510. The guide groove 510 can guide the movement of the connector 300, preventing the connector 300 from moving in a direction perpendicular to the axial direction of the drive rod 400, while also not affecting the axial deflection of the connector 300 relative to the drive rod 400.

[0031] Furthermore, the connector 300 includes a center seat 310 and a plurality of arms 320 connected to the center seat 310. The number and position of the arms 320 correspond to the number and position of the compression member 200. The spherical segment groove 301 is provided on the top surface of the center seat 310, and the through hole 302 also passes through the center seat 310. The guide seat 500 is provided with a receiving groove 520, and the center seat 310 is located in the receiving groove 520. The guide groove 510 communicates with the receiving groove 520 and extends to the side of the guide seat 500. The arms 320 pass through the guide groove 510 and are connected to the compression member 200.

[0032] The connecting member 300 of this embodiment is difficult to separate from the guide seat 500, and the guide seat 500 has a stronger guiding and limiting effect, and the central seat 310 is covered therein, which plays a certain protective role. The outwardly extending support arm 320 can slide in the guide groove 510 and can also deflect.

[0033] The receiving groove 520 passes through the guide base 500 so that the driving rod 400 can be connected to the driving system.

[0034] In some embodiments, the top surface of the workbench 100 is provided with a through-hole 101 extending therethrough. A connecting rod 330 extends through the through-hole 101. The upper end of the connecting rod 330 is connected to the pressing member 200, and the lower end is connected to the connecting member 300. When the connecting member 300 moves downward, the connecting rod 330 pushes the pressing member 200 downward. Compared to placing the connecting rod 330 outside the workbench 100, this embodiment achieves a more compact design, reducing the size of the fixture and minimizing space requirements.

[0035] When the connecting member 300 includes a central base 310 and a plurality of supporting arms 320 connected to the central base 310 , the lower end of the connecting rod 330 is connected to the supporting arms 320 .

[0036] Furthermore, one end of the pressing member 200 is rotatably connected to the workbench 100, and the other end is a pressing end. The upper end of the connecting rod 330 is rotatably connected to the middle part of the pressing member 200, and the lower end is rotatably connected to the connecting member 300. When the connecting member 300 moves downward, the connecting rod 330 pulls the pressing member 200 to rotate, so that the pressing end of the pressing member 200 presses on the workpiece 10. This method facilitates the removal and placement of the workpiece 10.

[0037] In some embodiments, a support column 210 is also fixed to the top surface of the workbench 100, and the support column 210 is located below the pressing end of the pressing piece 200. When the pressing end of the pressing piece 200 is pressed down, the pressing end of the pressing piece 200 and the support column 210 jointly clamp the workpiece 10 to clamp the workpiece 10 more firmly.

[0038] In some embodiments, the pressing members 200 are evenly distributed around the axis of the driving rod 400 to provide relatively uniform downward force. For example, when there are three pressing members 200, the three pressing members 200 can be distributed in an equilateral triangle.

[0039] In some embodiments, a protrusion 110 is also fixed to the top surface of the workbench 100. For a workpiece 10 with an opening, the protrusion 110 can be inserted into the opening of the workpiece 10 to position the workpiece 10, prevent the workpiece 10 from moving on the surface of the workbench 100, and further clamp the workpiece 10.
