DETAILED DESCRIPTION
[0017] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
[0018] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.
[0019] Examples, such as Figures 1 to 4As shown in the figure, a fixed-size sawing machine for guardrail plates includes a sawing machine body. The sawing machine body includes a support frame 1a1. On one side of the support frame 1a1, there is an installation frame 2. On the installation frame 2, there is a placement cover 3, which provides an effective installation position for the circular saw 18 equipment and facilitates its rotation adjustment, further improving the use functionality of the device. Above one side of the placement cover 3, there is a carrier plate 4, which provides a good bearing effect for one side of the workpiece to ensure the stability of the placed workpiece. At the same time, it also provides convenience for the abutment of one side of the workpiece. Below one side of the carrier plate 4, there is a limiting strip 41. Outside the limiting strip 41, there is a sleeve plate 5. Above the sleeve plate 5, there is a limiting plate 6. On one side of the sleeve plate 5, there is a locking screw 7. Specifically, the sleeve plate 5 is in a concave shape and sleeved on the limiting plate 6, and the outside of the sleeve plate 5 is connected to the limiting plate 6. In this way, when adjusting according to different cutting sizes of the workpiece, it is convenient to adjust the position of the limiting plate 6, and then screw the locking screw 7 to complete the limitation of the position of the sleeve plate 5 to prevent it from shaking, etc. In this way, one end face of the workpiece can abut against the limiting plate 6, and the movement process of the workpiece is more convenient, especially preventing it from shifting and ensuring the use requirements. A sliding rod 8 is horizontally arranged on the support frame 1a1. A moving block 9 is sleeved on the sliding rod 8. A moving plate 10 is arranged on the moving block 9. A connecting plate is also arranged between the moving plate 10 and the moving block 9. The purpose is to ensure that the four moving blocks 9 can be connected together and can move smoothly relative to the sliding rod 8. Of course, the positions of the moving block 9 and the connecting plate are close to one side corner of the moving plate 10, so as to increase its moving distance and ensure the use requirements. On one side of the moving plate 10, there is a positioning frame 11. Above the positioning frame 11, there is a concave frame 12. On the concave frame 12, there is a pressing plate 13 designed in a special-shaped L shape. Below the pressing plate 13 corresponding to the inside of the concave frame 12, there is a slider 14 designed in a T shape. A fixing screw 15 is arranged in the pressing plate 13 and passes through the slider 14. Further, the lower end of the slider 14 is fitted with the inside of the concave frame 12. According to the placement position of the workpiece, adjust the position of the pressing plate 13, especially make the lower end of the pressing plate 13 fit with the workpiece, and then screw the fixing screw 15 to fasten the position of the pressing plate 13. In this way, to a certain extent, the workpiece can be stably placed, especially preventing it from jumping vertically, improving safety and effectively meeting the use requirements.
[0020] The workpiece 5 is fixed to the workpiece 10 by the fixing screw 15, so that the fixing screw 15 can be fixed to the workpiece 10 by the fixing screw 15. The fixing screw 15 can be ...
[0021] In order to position the moving plate 10 when it reaches the farthest distance and prevent it from disengaging, square grooves are provided on both sides of the support frame 1a1. A strip-shaped plate 101 is arranged below the moving plate 10 corresponding to the square grooves. Among them, the lower side of the strip-shaped plate 101 is designed in a wedge shape, that is, one side of its lower end face is designed in an inclined shape from the side close to the anti-impact mechanism 16 to the side away from the anti-impact mechanism 16. The purpose is to ensure that the moving plate 10 can move forward as much as possible to ensure that the workpiece completes several operations. In addition, on the one hand, it can effectively improve the service strength of the moving plate 10, and on the other hand, its cooperation with the square groove can assist the slide rod 8 to limit the traveling direction of the moving plate 10 and prevent it from shifting. Further: an anti-impact mechanism 16 is arranged in one of the square grooves. The anti-impact mechanism 16 includes a mounting plate 161, an ear seat 162 is arranged on the mounting plate 161, a rotating plate 163 is arranged in the ear seat 162, a limiting wheel 164 is arranged on one side inside the rotating plate 163, and a lifting rod 165 is arranged at the geometric center of the mounting plate 161. Among them, for the established lifting rod 165, it is telescopic and a return spring is arranged inside. That is to say: when a force is applied to the upper end of the lifting rod 165, it will shorten and descend, and when the external force is removed, it will rise under the action of the return spring to achieve reset, ensuring the use effect. Specifically described as: when the moving plate 10 moves horizontally, the workpiece performs a cutting action. The strip-shaped plate 101 is pre-fitted with the anti-impact mechanism 16. Since the lower end face of the strip-shaped plate 101 is designed in an inclined shape, it will gradually press down the limiting wheel 164. As the workpiece gradually moves, the inclined surface angle gradually increases until the end face of the concave frame 12 on the moving plate 10 approaches the circular saw 18, and the inclined surface position transitions to a straight line position. At this time, the lifting rod 165 also descends to the lowest position and stops moving, and the limiting wheel 164 also stops rotating. In this way, the farthest distance reached by the moving plate 10 can be locked to prevent the moving plate 10 from disengaging. At the same time, the workpiece placed on the moving plate 10 has also completed the cutting work. When the subsequent processing work is to be carried out, the moving plate 10 is pulled in the direction away from the anti-impact mechanism 16 to reset it for waiting for the next processing work to proceed, ensuring the effective progress of the processing work and improving the work process.
[0022] In order to effectively improve the functional use of the device and equipment, especially to meet the usage requirements of various cutting angles of workpieces. Further: A rotating frame 17 is arranged inside the placement cover 3, a circular saw 18 is arranged inside the rotating frame 17, a vertical plate 19 is arranged on the outer side of the rotating frame 17, an arc-shaped groove 191 is formed inside the vertical plate 19, a fastening screw 20 is arranged inside the arc-shaped groove 191, and one end of the fastening screw abuts against the outer side of the rotating frame 17. Specifically described as: The rotating frame 17 is designed in a concave shape, and its internal dimension specifications are adapted to the circular saw 18 to ensure that the circular saw 18 can be stably installed in the rotating frame 17. A rotating shaft is arranged above one side of the rotating frame 17, and the rotating shaft penetrates through the vertical plate 19 and is set on the placement cover 3. In this way, the rotating frame 17 can rotate longitudinally, thereby driving the saw blade of the circular saw 18 to deflect towards one side to ensure the chamfering work. In addition, the vertical plate 19 is fixedly arranged relative to the rotating frame 17. A positioning hole is formed inside the rotating frame 17, and the opening radian of the arc-shaped groove 191 coincides with the trajectory of the positioning hole when the rotating frame 17 rotates. That is to say, when the rotating frame 17 rotates to a suitable position, the fastening screw 20 is adjusted along the arc-shaped groove 191 until one end of the fastening screw abuts against the positioning hole, and then the fastening screw 20 is screwed to cooperate with the positioning hole, thereby completing the fastening of the position of the rotating frame 17, preventing it from shifting, ensuring the stability of the position of the device and equipment, and guaranteeing the use safety.
[0023] In order to further improve the rationality of the device and equipment, a driving cylinder 21 is arranged below inside the placement cover 3. The output end of the driving cylinder 21 is provided with a connecting seat 22, which is hinged to the lower part of the rotating frame 17. Specifically described as: A process groove is formed on the carrier plate 4 near the saw blade of the circular saw 18, and a detachable plate member is placed in the process groove. When direct cutting of the workpiece is required, that is, when no special angle cutting is needed, the plate member is placed in the process groove, which to a certain extent also guarantees the effective progress of the processing work. When chamfering treatment or cutting at a special angle of the workpiece is required, the plate member is manually removed, and then the driving cylinder 21 is controlled to operate, and its elongation is used to drive the rotating frame 17 to rotate and adjust to ensure the effective realization of the cutting angle. At the same time, after the driving cylinder 21 drives the rotating frame 17 to rotate, the fastening screw 20 is screwed to abut against the outer side of the rotating frame 17 to play a fastening role in its position, guarantee the stability, ensure the safety during the cutting work, and meet the usage requirements.
[0024] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
