[0003] There is a lack of instant fixation function for the workpiece. Instant fixation means that the workpiece can be quickly fixed or loosened according to the actual processing situation. When the workpiece is transported to the sawing machine through the feeding device and one end of it is cut, the other end of the workpiece needs to be fixed to prevent the workpiece from warping and affecting the processing accuracy. When the workpiece is cut, the fixation of the workpiece needs to be loosened so that the cut workpiece can continue to be transported.

[0004] Therefore, in order to solve the defect that the sawing machine cannot immediately fix the workpiece when in use, it is necessary to propose an electric sawing machine that is convenient for immediately fixing the workpiece. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In order to solve the technical problem of how electric sawing machines can achieve automatic cutting of workpieces, please refer to Figure 1-Figure 3 , this embodiment provides the following technical solutions:

[0027] An electric sawing machine which is convenient for instantly fixing a workpiece comprises a feeding mechanism 1, a bed 2 and a material receiving trough 3. The feeding mechanism 1 comprises a conveying frame 11, anti-deviation components 13 installed at the left and right ends of the conveying frame 11 and an instant fixing component 14 installed at the end of the conveying frame 11. A plurality of rollers 12 for feeding are movably installed in the conveying frame 11.

[0028] The upper end of the bed 2 is slidably connected to a saw beam 22 through a column 21, and a saw blade 23 is movably connected to the saw beam 22 through a saw wheel. A material receiving trough 3 is fixedly installed at one end of the bed 2 and its material receiving port is located directly below the saw blade 23. A material slope 31 is provided at one end of the material receiving trough 3 close to the bed 2.

[0029] Specifically, the workpiece is placed on the conveying frame 11, and the roller 12 is started at this time, so that the roller 12 rotates and drives the workpiece to move for feeding. The anti-deviation component 13 prevents the workpiece from being offset during feeding. When the end of the workpiece that needs to be cut moves under the saw blade 23, the workpiece is quickly fixed by the instant fixing component 14, and then the saw beam 22 is started, so that the saw beam 22 moves down along the column 21 to cut the workpiece. The cut workpiece slides into the material receiving trough 3 along the material slope 31, and the remaining workpiece continues to remain on the conveying frame 11. At this time, the fixation of the workpiece is released so that the remaining workpiece can be conveyed by the roller 12 until it falls into the material receiving trough 3.

[0030] To solve the technical problem of how to prevent the workpiece from deflecting during transportation, please refer to Figure 4 , this embodiment provides the following technical solutions:

[0031] The anti-deviation assembly 13 includes a correction frame 131, one end of which is movably mounted with a plurality of rollers 132, and the other end is symmetrically welded with a positioning shaft 134, and the positioning shaft 134 is equidistantly provided with positioning holes 135, and the outer wall of the conveying frame 11 is mounted with a shaft sleeve 15 matched with the positioning shaft 134, and the shaft sleeve 15 is fixed to the positioning shaft 134 by a positioning pin.

[0032] The anti-deviation assembly 13 further includes a first cylinder 133 , which is fixed to the side end of the outer wall of the conveying frame 11 , and is connected to the correction frame 131 via a piston rod.

[0033] Specifically, after the workpiece is placed on the conveyor rack 11, the position of the correction frame 131 is adjusted according to the size of the workpiece, and the two left and right first cylinders 133 are started, so that the first cylinders 133 drive the correction frame 131 to move toward the side wall of the workpiece. At this time, the positioning shaft 134 slides in the sleeve 15 until the roller 132 fits with the side wall of the workpiece, and the positioning pin is inserted into the sleeve 15 and the corresponding positioning hole 135 to fix the sleeve 15 and the positioning shaft 134. Then, the roller 12 is started, so that the roller 12 drives the workpiece to move, and the correction frame 131 is used to prevent the workpiece from shifting.

[0034] It should be noted that the arrangement of the positioning shaft 134 and the sleeve 15 can prevent the correction frame 131 from being offset as a whole, so that the correction frame 131 can maintain balance with the wall of the conveyor frame 11, further improving the anti-deviation function of the workpiece.

[0035] To solve the technical problem of how to fix the workpiece immediately on the saw machine, please refer to Figure 5 , this embodiment provides the following technical solutions:

[0036] The instant fixing component 14 includes a baffle 141, which is fixedly installed above the end of the conveying frame 11. A second cylinder 142 is installed on the baffle 141. The second cylinder 142 is connected to a fixing plate 143 for fixing the workpiece through a piston rod. The fixing plate 143 is lifted and lowered at the lower end of the baffle 141, and the left and right ends of the fixing plate 143 are slidably connected to the conveying frame 11 through a slide groove 144.

[0037] Specifically, when one end of the workpiece that needs to be cut moves to the lower end of the saw blade 23, the second cylinder 142 is started, and the second cylinder 142 drives the fixed plate 143 to move downward, so that the fixed plate 143 presses the workpiece to complete the fixation of the workpiece and prevent one end of the workpiece from tilting up during cutting. After the cutting is completed, the second cylinder 142 is started again. At this time, the second cylinder 142 drives the fixed plate 143 to move upward, loosening the fixation of the workpiece so that the workpiece can continue to move for feeding.

[0038] It should be noted that the slide groove 144 is provided to make the fixing plate 143 more directional when it is lifted or lowered, so as to prevent the fixing plate 143 from deviating.

[0039] Working principle: When using the electric sawing machine which is convenient for instantly fixing the workpiece, the workpiece is first placed on the conveying frame 11, and then the position of the correction frame 131 is adjusted according to the size of the workpiece until the roller 132 is in contact with the side end of the workpiece, and the roller 12 is started to drive the workpiece to move for loading, until the end of the workpiece to be cut moves under the saw blade 23, the roller 12 is closed, and the second cylinder 142 is started. The second cylinder 142 drives the fixed plate 143 to move downward to fix the workpiece, and then the saw beam 22 and the saw blade 23 are started to cut the workpiece. The cut workpiece automatically slides into the receiving trough 3, and the remaining workpiece continues to remain on the conveying frame 11, and then the second cylinder 142 is started to drive the fixed plate 143 to move upward to release the fixation of the workpiece, and then the roller 12 is started, so that the remaining workpiece can continue to move for loading until the entire workpiece is cut.
