Plate cutting saw with guide device

Technical Field

The invention belongs to the technical field of cutting tools, and particularly discloses a plate cutting saw with a guide device.

Background

With the continuous improvement of the appearance and quality requirements of people on furniture, a large number of plates are applied to the furniture and decoration industry, a traditional plate cutting tool is generally a circular saw, however, the machining precision and the production efficiency of the circular saw cannot meet the requirements of the existing plate machining process, and various plate cutting saws appear on the market at present.

Chinese patent publication No. CN104149134A discloses a carpentry board cutting saw with simple and safe operation, which comprises a frame, wherein the left side of the frame is connected with a fixed working platform; a saw blade is arranged on the fixed working platform, and a protective cover is arranged above the saw blade; a sliding push table is arranged on the right side of the fixed working platform and is connected with the rack through a guide rail; the guide rail is connected with a fixing frame, the fixing frame is provided with a hydraulic device, and the hydraulic device is connected with the pressing plate through a hydraulic rod; the pressing plate is located above the sliding pushing table, a rubber pad is connected to the pressing plate, a supporting frame is connected to the lower portion of the sliding pushing table, and rollers are arranged at the bottom of the supporting frame. According to the automatic plate pressing device, the automatic plate pressing is realized through the hydraulic device, the hydraulic rod and the pressing plate, so that the labor intensity is reduced, the safety is improved, and the saw cutting work is facilitated.

In the scheme, a hydraulic device is adopted to press the wood board, but when the wood board is cut, particularly when the cutting direction is not at the center of the wood board, the saw blade can generate thrust to the wood board, and the thrust can deflect the wood board on a horizontal plane, and finally the wood board is cut into an irregular shape.

Disclosure of Invention

The invention aims to provide a board cutting saw with a guide device to solve the problem that a wood board is easy to displace in the cutting process.

In order to achieve the purpose, the basic scheme of the invention is as follows: the plate cutting saw with the guide device comprises a rack, wherein a support table and a guide rail unit are arranged on the rack, the guide rail unit is positioned below the support table, a slide seat is connected onto the guide rail unit in a sliding manner, a first rotating shaft is connected onto the slide seat in a rotating manner, a first motor is fixedly arranged on the first rotating shaft, and the output end of the first motor is horizontally arranged and provided with a saw blade; the saw blade fixing device is characterized in that a fixing unit is arranged on the rack and comprises a fixing plate and a sliding plate, the fixing plate and the sliding plate are respectively positioned on two opposite sides of the supporting table, the fixing plate is fixedly arranged on the rack, two sets of same induction mechanisms are arranged on one side, facing the supporting table, of the fixing plate, each induction mechanism comprises a spring and a stop block, one end of each spring is fixedly arranged on the fixing plate, the other end of each spring is fixedly connected with the stop block, each stop block can abut against a wood plate, the two stop blocks are respectively positioned on two sides of the saw blade, a second guide rail is arranged on the rack, the sliding plate is slidably connected onto the second guide rail, the sliding plate can abut against the; be equipped with two sets of guide unit in the frame, two sets of guide unit correspond with two sets of induction mechanism respectively, guide unit includes second axis of rotation, drive belt and rack, the second pivot is rotated and is set up in the frame, and the second pivot is located the one side that deviates from the saw bit on the dog, be equipped with the gear in the second pivot, the one end of drive belt is fixed and twines in first pivot, the other end of drive belt is fixed and twines in the second pivot, the rack sets up the one side that deviates from the saw bit on the dog and with gear engagement.

The working principle of the basic scheme is as follows: the plank to be processed is placed on the supporting table, then the sliding plate is slid manually, so that the sliding plate abuts against the plank, the plank abuts against the stop block, the spring is compressed under stress, after the sliding plate cannot move, the electromagnet is started, the sliding plate is fixed by the electromagnet, and the plank is fixed on the supporting table. Start first motor, first motor drives the saw bit and rotates, the saw bit cuts processing to the plank, when the skew takes place for the plank, suppose the plank deflects towards the right side, the fixed plate is kept away from gradually in the left side of plank this moment, the spring on the left side extends gradually, the rack on the left side removes and drives the gear anticlockwise rotation rather than the meshing, the gear drives second pivot anticlockwise rotation and receives and draws the drive belt, the drive belt drives first pivot clockwise, first motor and saw bit clockwise rotation are driven to first pivot, so when the plank deflects right, first motor and saw bit also can rotate right, guarantee that the relative position of saw bit and plank keeps unchangeable constantly, make the plank can be cut the shaping.

The beneficial effect of this basic scheme lies in: 1. in this scheme, if the plank takes place to deflect, the saw bit also can rotate along with the direction that the plank deflected, and relative position between them keeps unchangeable, guarantees that the plank can be cut the shaping. 2. Utilize spring and dog to fix the plank in this scheme, the saw bit is when the cutting plank, if the thrust of saw bit is too big, the plank can continue to compress one section distance towards the direction of spring, and the plank can be given to the spring this moment and saw bit buffer power, avoids plank and saw bit to be broken.

Furthermore, the support table comprises a plurality of cross-shaped support frames which are fixedly arranged on the frame, all the support frames are horizontally arranged and arranged in a rectangular array, and a gap for the saw blade to pass through is formed between every two adjacent support frames; the guide rail unit comprises a plurality of first guide rails which are communicated in a criss-cross mode, and the sliding seat is connected to the first guide rails in a sliding mode. This scheme of adoption, the saw bit can pass the space between two adjacent support frames, and the first motor of being convenient for and saw bit remove. Meanwhile, if a plurality of supporting frames are arranged, gaps among the supporting frames are large, and the saw blade has a plurality of movable paths, so that the saw blade can saw wood boards into various shapes. In the scheme, the first guide rails are criss-cross, so that the sliding seat has multiple sliding paths and can have more processing shapes.

Further, adjacent two be formed with the accommodation space of square between the first guide rail, be equipped with the second motor below two accommodation spaces of diagonal, all the other accommodation space's below is equipped with the third pivot, the third pivot is rotated and is connected in the frame, the fixed setting of second motor is in the frame, the vertical setting of output of second motor, and all establishes the friction pulley in the output of second motor and the third pivot, the friction pulley is located accommodation space's center department, one side that is close to the friction pulley on the first guide rail is equipped with a plurality of logical grooves, the friction pulley stretches into logical inslot, and the friction pulley can offset with the lateral wall of slide. This scheme of adoption starts the second motor, and the second motor drives the friction pulley and rotates, and when the friction pulley contacted with the slide, the slide moved forward under its kinetic friction effect with the friction pulley, need not the manual work and promotes the slide.

Furthermore, two limiting cylinders are arranged on the rack, and the stop block is inserted into the limiting cylinders. This scheme of adoption can be spacing with the dog, makes it can only move towards the flexible direction of spring.

Further, the transmission belt is made of a leather material. This scheme of adoption, the drive belt toughness of cortex structure is strong, long service life.

Further, the width of the transmission belt is 2 cm.
