Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, specifically a rapid clamping device for mechanical manufacturing equipment. Background Technology

[0002] In the machining process, the positioning and installation of the workpiece is an important step. The accuracy of the workpiece positioning and installation determines the basic accuracy of the machining to a certain extent. The positioning and installation of the workpiece on the machine tool is usually accomplished by positioning fixtures and clamping fixtures. Clamping fixtures are generally divided into ordinary clamping fixtures and quick clamping fixtures. The main representative of quick clamping fixtures is the quick clamp. In actual production, the corresponding quick clamping fixture is selected according to different workpieces.

[0003] Based on the above findings of the inventors, the existing quick clamping device for mechanical manufacturing equipment has the following main shortcomings. For example, when processing glass workpieces, it is necessary to fix the end face of the glass workpiece to avoid displacement during processing. Furthermore, when the pressing device presses down on the glass workpiece, friction can easily leave indentations on the end face of the glass workpiece. When processing glass workpieces with inclined end faces, the end face of the pressing block will form a certain angle with the end face of the glass workpiece, resulting in the end face of the glass workpiece not being completely pressed down by the pressing block, causing the workpiece to easily shift during processing. Summary of the Invention

[0004] To address the above problems, the present invention provides a rapid clamping device for mechanical manufacturing equipment.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a quick pressing device for mechanical manufacturing equipment, the structure of which includes a processing table, a support plate, a support column, and a main body.

Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Example 1: Please refer to Figures 1-5 The specific embodiments of the present invention are as follows: Its structure includes a processing table 1, a support plate 2, a support column 3, and a main body 4. The support plate 2 is located at the top center of the processing table 1. The support column 3 is vertically installed on the top side of the processing table 1. The main body 4 is connected to the top of the support column 3.

[0024] The main body 4 includes a mounting plate 41, a connecting hole 42, a telescopic plate 43, a hydraulic telescopic rod 44, an adjusting device 45, and a pressing device 46. The mounting plate 41 has a connecting hole 42 on its end face, which is connected to the end face of the support column 3. The telescopic plate 43 is engaged with the inner end face of the mounting plate 41. The side end face of the hydraulic telescopic rod 44 is engaged with the end of the telescopic plate 43. One end of the adjusting device 45 is connected to the side end face of the hydraulic telescopic rod 44, and the other end of the adjusting device 45 is connected to the top end face of the telescopic plate 43. The pressing device 46 is fixedly connected to the bottom end face of the hydraulic telescopic rod 44. The adjusting device 45 and the hydraulic telescopic rod 44 are movably coordinated, which facilitates the telescopic plate 43 to extend and retract inside the mounting plate 41, and allows the position of the telescopic plate 43 to be adjusted by moving it back and forth.

[0025] The adjusting device 45 includes a mounting base 451, a threaded engagement frame 452, a threaded rod 453, an engagement head 454, a connecting rod 455, and a locking shaft 456. The mounting base 451 is fixedly connected to the top end face of the telescopic plate 43. The two sides of the threaded engagement frame 452 engage with the mounting base 451. The threaded rod 453 passes through the interior of the threaded engagement frame 452. The engagement head 454 is fixedly connected to the end of the threaded rod 453. The connecting rod 455 engages with the interior of the engagement head 454. The locking shaft 456 passes through the interior of the threaded engagement frame 452. The connecting rod 455 is connected to the end face of the connecting rod 455, and the locking shaft 456 is movably engaged with the side end face of the hydraulic telescopic rod 44. The threaded rod 453 is threadedly engaged with the threaded engagement frame 452, which facilitates the rotation of the engagement head 454 to drive the threaded rod 453 to rotate forward, so that the threaded rod 453 can move to the right side of the end face of the threaded engagement frame 452, allowing the end face of the connecting rod 455 to drive the bottom of the hydraulic telescopic rod 44 to swing to the left, so that the pressing device 46 placed at the bottom end of the hydraulic telescopic rod 44 can be parallel to the inclined end face of the glass workpiece.

[0026] The engaging head 454 includes an engaging block a1, a rotating rod a2, and an engaging groove a3. The engaging block a1 is fixedly connected to the end of the threaded rod 453. The rotating rod a2 passes through the end face of the engaging block a1. The engaging groove a3 is located inside the engaging block a1 and is movably engaged with the connecting rod 455. The rotating rod a2 is engaged with the inner end face of the engaging block a1, which facilitates the movement of the connecting rod 455 through the engaging groove a3, allowing the hydraulic telescopic rod 44 to swing left and right to adjust its angle.

[0027] The threaded engagement frame 452 includes a frame b1, a rotating shaft b2, a top block b3, and a threaded rack b4. The two end faces of the frame b1 are connected to the rotating shaft b2. There are two rotating shafts b2, and the rotating shaft b2 engages with the end face of the mounting base 451. The top block b3 is fixedly connected to the end of the rotating shaft b2. The threaded rack b4 is disposed inside the frame b1 and is movably engaged with the threaded rod 453. This allows the frame b1 to swing up and down with the threaded rod 453 via the rotating shaft b2, preventing the threaded rod 453 from getting stuck.

[0028] Based on the above embodiments, the specific working principle is as follows: When clamping a glass workpiece, the telescopic plate 43 can be extended and retracted inside the mounting plate 41, thereby moving the position of the telescopic plate 43 back and forth, so that the bottom of the hydraulic telescopic rod 44 is aligned with the top of the glass workpiece. This allows the hydraulic telescopic rod 44 to drive the pressing device 46 to move vertically downward, enabling the pressing device 46 to press the end face of the glass workpiece for processing. Then, the rotating locking head 454 drives the threaded rod 453 to rotate clockwise, allowing the threaded rod 453 to move to the right side of the end face of the threaded locking frame 452. This allows the end face of the connecting rod 455 to drive the bottom of the hydraulic telescopic rod 44 to swing to the left. Conversely, rotating the locking head 454 drives the threaded rod 453 to rotate counterclockwise. Reversing the threaded rod 453 allows it to move to the left from the end face of the threaded engagement frame 452, enabling the end face of the connecting rod 455 to swing the bottom of the hydraulic telescopic rod 44 to the right. This allows the pressing device 46 at the bottom of the hydraulic telescopic rod 44 to be parallel to the inclined end face of the glass workpiece. Then, the engaging groove a3 is used to move the connecting rod 455, allowing the hydraulic telescopic rod 44 to swing left and right to adjust its angle. Finally, when the threaded rod 453 and the threaded rack b4 are in active engagement, the frame b1 can swing up and down with the threaded rod 453 via the rotating shaft b2, preventing the threaded rod 453 from jamming and improving the stability of the engagement between the threaded rod 453 and the threaded rack b4.

[0029] Example 2: Please refer to Figures 6-7 The specific embodiments of the present invention are as follows: The pressing device 46 includes a pressing plate c1, a rotating head c2, a handle c3, and a buffer pad c4. The rotating head c2 is provided on the top end face of the pressing plate c1. The rotating head c2 is connected to the bottom end face of the hydraulic telescopic rod 44. The handle c3 is fixedly connected to the top right end face of the pressing plate c1. The buffer pad c4 is embedded in the bottom end face of the pressing plate c1. The rotating head c2 is movably engaged with the end face of the pressing plate c1, which facilitates rotation through the end face of the rotating head c2, allowing the end face of the pressing plate c1 to be flush with the glass workpiece that is tilted in multiple directions.

[0030] The buffer pad c4 includes an embedded block a41, a contact pad a42, a buffer groove a43, and a friction groove a44. The embedded block a41 is fixedly embedded in the bottom end face of the lower pressure plate c1. The contact pad a42 is fixedly connected to the bottom end face of the embedded block a41. There are three or more buffer grooves a43, which are arranged on the inner end face of the contact pad a42. There are four or more friction grooves a44, which are arranged laterally on the bottom end face of the contact pad a42. The contact pad a42 is made of rubber, which helps to increase the friction between the contact pad a42 and the glass workpiece through the friction grooves a44, so that the lower pressure plate c1 can stably press the glass workpiece.

[0031] Based on the above embodiments, the specific working principle is as follows: The lifting handle c3 drives the lower pressure plate c1 to rotate the end face of the rotating head c2, so that the end face of the lower pressure plate c1 is flush with the glass workpiece that is tilted in multiple directions, allowing the lower pressure plate c1 to press down on the glass workpiece stably and improve the stability of the glass workpiece during processing. Then, the rubber contact pad a42 contacts the end face of the glass workpiece, and the friction groove a44 increases the friction between the contact pad a42 and the glass workpiece, allowing the lower pressure plate c1 to press the glass workpiece stably. During the pressing of the glass workpiece, the contact pad a42 can deform into the buffer groove a43 to prevent scratches on the end face of the glass workpiece.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0033] Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
