Description

Technical Field

[0001] The utility model relates to the field of plate processing and fixing, in particular to a pressing and fixing device for small-sized plates. Background Technique

[0002] When performing processing operations such as drilling on a plate, it is necessary to press and fix the plate on the processing table. The existing processing tables generally can only fix large plates with sizes not much different from theirs. When the size of the plate is small, the contact area between the pressing and fixing device and the plate accounts for too large a proportion relative to the size of the plate, and it is very easy to interfere with the drilling position on the plate, resulting in large limitations on the size of the processed plates by the existing processing tables and making it difficult to meet the fixing requirements for processing small-sized plates. Content of the Utility Model

[0003] The purpose of the utility model is to provide a pressing and fixing device for small-sized plates, which can solve the technical problem that it is not convenient to fix small-sized plates during processing. It only rises above the processing table when processing small-sized plates to press and fix the edges of the small-sized plates, reducing the contact area with the small-sized plates and reducing the possible interference with the drilling position, meeting the fixing requirements for processing small-sized plates.

[0004] In order to achieve the above object, the utility model is realized through the following technical solutions:

[0005] A pressing and fixing device for small-sized plates includes a processing table. Transverse hidden holes and longitudinal hidden holes are arranged crosswise on the processing table. Slide seats are symmetrically and slidably connected in both the transverse hidden holes and the longitudinal hidden holes. Power rods for driving the slide seats to slide are arranged in both the transverse hidden holes and the longitudinal hidden holes. A support rod is slidably connected vertically on the slide seat. A transverse pressing plate is arranged at the top of the support rod. A lifting rod for driving the support rod to slide up and down is arranged on the slide seat.

[0006] Further, two thread regions with opposite helix directions are arranged on the power rod. The two thread regions respectively penetrate through the two slide seats and are threadedly connected with them. A motor is arranged on the processing table. The power rod is connected to the output shaft of the motor.

[0007] Further, the power rods in the transverse hidden holes and the longitudinal hidden holes are located at different heights.

[0008] Further, two support rods on each slide seat are symmetrically arranged. Through holes are symmetrically arranged on the slide seat and are symmetrically located on both sides of the power rod. The support rods pass through the through holes and are slidably connected with them.

[0009] Further, a connecting rod is arranged between the bottoms of the two support rods. The movable end of the lifting rod is fixedly connected to the connecting rod.

[0010] Furthermore, anti-slip stripes are provided at the bottom of the pressing plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, crosswise hidden holes and longitudinal hidden holes are provided on the processing table. Slide seats are slidably connected inside both of them. A support rod is slidably connected vertically along the slide seat. A horizontal pressing plate is provided at the top of the support rod. When processing small-sized plates, the lifting rod is used to drive the support rod to rise, so that the pressing plate passes through the crosswise hidden holes and longitudinal hidden holes and then rises above the processing table. Then, the small-sized plate is placed on the processing table. After that, the lifting rod is used to drive the support rod to descend, so that the pressing plate at the top of the support rod descends and presses against the edge of the small-sized plate, realizing the pressing and fixing of the small-sized plate. This pressing and fixing method makes the contact area between the pressing plate and the small-sized plate smaller, and will not interfere with the drilling positions on the small-sized plate, meeting the processing requirements of small-sized plates. When processing large-sized plates, the lifting rod drives the support rod to descend, so that the pressing plate descends into the crosswise hidden holes and longitudinal hidden holes, enabling the large-sized plate to be placed flat on the processing table and fixed by its original pressing and fixing device, without interfering with the fixing of the large-sized plate, improving the adaptability to the processing of different-sized plates;

[0013] 2. The slide seat is driven to slide by the power rod. After the small-sized plate is placed on the processing table, the power rod can be used to drive the slide seats on both sides to slide relatively until the support rods on both sides are in contact with both sides of the small-sized plate, thus automatically realizing the centering operation of the placement position of the small-sized plate. When the support rods on the two slide seats slide downward, the pressing plate at the top can accurately press on the plate. Moreover, the small-sized plate can have multiple sizes with little difference, improving the convenience and accuracy of pressing and fixing the small-sized plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following further elaborates the present utility model in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0022] Refer to Figure 1 and Figure 2, the present utility model relates to a pressing and fixing device for small-sized plates. The main structure includes a processing table 1, which is used to place the plates and is provided with a plurality of support legs at the bottom. The processing table 1 is provided with a horizontally hidden hole 2 and a vertically hidden hole 3 that are cross-set, and both cross through the processing table 1. The horizontally hidden hole 2 and the vertically hidden hole 3 are both symmetrically slidably connected with a sliding seat 4, and the sliding seat 4 slides in the horizontal plane. The horizontally hidden hole 2 and the vertically hidden hole 3 are both provided with a power rod 5 for driving the sliding seat 4 to slide. The power rod 5 is used to drive the two sliding seats 4 in the horizontally hidden hole 2 and the vertically hidden hole 3 to slide relatively or away from each other simultaneously. A support rod 6 is slidably connected to the sliding seat 4 in the vertical direction. The top of the support rod 6 is welded or bolt-fixed with a horizontal pressing plate 7. The sliding seat 4 is provided with a lifting rod 8 for driving the support rod 6 to slide up and down. The lifting rod 8 can specifically adopt an air cylinder or an electric cylinder in the existing technology. With such a structure, when the lifting rod 8 extends, it can drive the pressing plate 7 to extend from the horizontally hidden hole 2 and the vertically hidden hole 3 to the upper part of the processing table 1 under the drive of the support rod 6. Then, the power rod 5 drives the two sliding seats 4 on both sides to slide relatively, driving the pressing plates 7 on both sides to move relatively until the support rods 6 on both sides contact the two sides of the small-sized plate. Then, the lifting rod 8 contracts, and under the drive of the support rod 6, the pressing plate 7 descends and presses on the edge of the small-sized plate, realizing the effective fixation of the small-sized plate. The contact area with the small-sized plate is greatly reduced, reducing the possible interference to the drilling position and meeting the fixation requirements during the processing of small-sized plates. When the lifting rod 8 contracts, under the drive of the support rod 6, the pressing plate 7 is driven to slide downward and hidden into the horizontally hidden hole 2 and the vertically hidden hole 3, so that it only plays a role when processing small-sized plates. When processing large-sized plates, it is hidden in the processing table 1 and will not interfere with the placement of large-sized plates. Large-sized plates are still fixed by the original pressing and fixing device. Without affecting the original processing and fixation of large-sized plates, the convenience of pressing and fixing small-sized plates is greatly improved.

[0023] Preferably, the power rod 5 is provided with two thread regions with opposite helix directions. The two thread regions respectively penetrate through the two sliding seats 4 and are threadedly connected with them. The processing table 1 is welded or bolt-fixed with a motor 9, and the power rod 5 is welded or bolt-fixed to the output shaft of the motor 9. With such a structure, when the motor 9 drives the power rod 5 to rotate, under the action of the two thread regions, the two sliding seats 4 on both sides slide relatively or away from each other simultaneously, making the sliding drive of the two sliding seats 4 on both sides more synchronous and efficient, improving the accuracy and convenience of the sliding drive of the sliding seat 4.

[0024] Preferably, referring to Figure 3 and Figure 4, the power rods 5 in the horizontal hidden holes 2 and the vertical hidden holes 3 are located at different heights respectively. Such a structure enables the two power rods 5 not to interfere with each other at different heights, so that the two power rods 5 can respectively drive the sliding seats 4 to slide in the horizontally and vertically hidden holes 2 arranged crosswise, making the positions of the two power rods 5 more reasonable and improving the smoothness of the overall operation of the device.

[0025] Preferably, referring to Figure 5 , there are two symmetrically arranged support rods 6 on each sliding seat 4. Through holes 10 are symmetrically arranged on the sliding seat 4. The through holes 10 penetrate through the sliding seat 4 and are symmetrically located on both sides of the power rod 5. The support rods 6 pass through the through holes 10 and are slidably connected thereto. Such a structure enables the support rods 6 on both sides to provide more stable and uniform support for the pressing plate 7, so that when the pressing plate 7 slides downward to press and fix the plate, a more uniform and stable pressing force can be provided for the pressing plate 7, further improving the firmness of pressing and fixing the plate.

[0026] Preferably, a connecting rod 11 is welded or bolt-fixed between the bottoms of the two support rods 6. The movable end of the lifting rod 8 is welded or bolt-fixed to the connecting rod 11. Such a structure enables the telescopic rod to directly drive the two support rods 6 on both sides to slide simultaneously under the connection of the connecting rod 11 during the telescopic movement, making the sliding drive of the two support rods 6 on both sides more uniform and stable, and further improving the stability of the up and down sliding movement of the support rods 6 and the pressing plate 7.

[0027] Preferably, anti-slip stripes 12 are provided at the bottom of the pressing plate 7. Such a structure enables the pressing plate 7 to have a greater pressing force when pressing the plate, and the pressing and fixing effect is better, effectively avoiding the movement and misalignment of the plate during the processing, and further improving the accuracy of the processing.

[0028] Working principle: In this utility model, transverse hidden holes 2 and longitudinal hidden holes 3 are arranged in a cross shape on the processing table 1. A sliding seat 4 is slidably connected inside both of them. A support rod 6 is slidably connected vertically on the sliding seat 4. A transverse pressing plate 7 is provided at the top of the support rod 6. When processing small-sized plates, with such a structure, the lifting rod 8 is used to drive the support rod 6 to rise, so that the pressing plate 7 passes through the transverse hidden hole 2 and the longitudinal hidden hole 3 and then rises above the processing table 1. Then, the small-sized plate is placed on the processing table 1. After that, the lifting rod 8 is used to drive the support rod 6 to descend, so that the pressing plate 7 at the top of the support rod 6 descends and presses on the edge of the small-sized plate, realizing the pressing and fixing of the small-sized plate. Such a pressing and fixing method makes the contact area between the pressing plate 7 and the small-sized plate smaller, and will not interfere with the drilling positions on the small-sized plate, meeting the processing requirements of small-sized plates. When processing large-sized plates, the lifting rod 8 drives the support rod 6 to descend, so that the pressing plate 7 descends into the transverse hidden hole 2 and the longitudinal hidden hole 3, enabling the large-sized plate to be placed flat on the processing table 1 and fixed by its original pressing and fixing device without interfering with the fixing of the large-sized plate, improving the adaptability to the processing of plates of different sizes. The sliding seat 4 is driven to slide by the power rod 5. With such a structure, after the small-sized plate is placed on the processing table 1, the power rod 5 can be used to drive the sliding seats 4 on both sides to slide relatively until the support rods 6 on both sides are in contact with both sides of the small-sized plate, thereby automatically realizing the centering operation of the placement position of the small-sized plate. When the support rods 6 on the two sliding seats 4 slide downward, the pressing plate 7 at the top can accurately press on the plate. Moreover, the small-sized plate can have multiple sizes with little difference, improving the convenience and accuracy of pressing and fixing the small-sized plate.
