Description

Technical Field

[0001] This utility model belongs to the field of sawing technology, and more specifically, it relates to a saw that facilitates workpiece fixation. Background Technology

[0002] A saw is a mechanical device used to cut various types of metal or wood workpieces. The saw utilizes a series of saw teeth on a saw blade to cut metal or wood workpieces to the required length. Currently, to ensure the accuracy and precision of the cut, saws typically use clamps to hold the workpiece in place. However, in actual cutting, a group of workpieces often needs to be adjusted multiple times for segmented cutting. Each time the workpiece's cutting position is changed, the saw operator must loosen and release the clamp, then hold the workpiece and move its cutting position to the saw blade's cutting surface, before re-secureing it. Therefore, traditional saw clamps cannot quickly adjust the workpiece's cutting position, and the repeated loosening and repositioning of the clamps is cumbersome and inconvenient. Furthermore, traditional saw clamps only use two sets of clamping plates to hold the workpiece from left to right, without any clamping measures for the upper and lower parts of the workpiece. During the downward cutting process of the saw teeth, the workpiece is prone to slight tilting and flipping, affecting the flatness and precision of the cut surface and the overall cutting quality.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1-8 As shown, this utility model provides a band saw for easy workpiece fixing, including a bed 1; a control unit 2 is installed on the left side of the bed 1, a hydraulic oil supply station 3 is installed on the upper side of the bed 1 near the left end, and a band saw 4 is hinged to the upper side of the bed 1 near the right end; it also includes a workpiece adjustment and clamping device 5; the workpiece adjustment and clamping device 5 includes a base frame 501, a hydraulic cylinder 502, an adjusting knob 503, a slide 504, a threaded adjusting rod 505, a guide rod 506, a cutting workpiece 507, a clamping plate 508, a guide column 509, a lifting frame 510, a lifting knob 511, a baffle 512, a limiting plate 513, a spring 514, a chip box 515, and a threaded rotating rod 516; the adjusting knob 503 is welded to the threaded adjusting rod 505, and the outer side of the threaded adjusting rod 505 near the front end is connected to... A base frame 501 is rotatably connected to the unthreaded surface at the rear end. A bed 1 is bolted to the lower side of the base frame 501. A chip box 515 is placed on the upper side of the bed 1. The base frame 501 is welded to both the front and rear ends of the guide rod 506. A slide block 504 is slidably connected to the outer side of the guide rod 506. A cutting workpiece 507 is placed on the upper side of the slide block 504. A hydraulic cylinder 502 is installed on the left side of the slide block 504. A clamping plate 508 is bolted to the right end of the telescopic rod of the hydraulic cylinder 502. A guide post 509 is welded to the upper side of the slide block 504. A spring 514 is nested on the outer side of the guide post 509. A lifting knob 511 is welded to the top of the threaded rotating rod 516. A lifting frame 510 is rotatably connected to the outer side of the threaded rotating rod 516. A limit plate 513 is engaged with the outer side of the threaded rotating rod 516.

[0024] In this embodiment, a square through slot is provided on the upper side of the slide 504 near the right end. The lifting frame 510 is inserted into the square through slot of the slide 504. A long through slot is provided on the upper side of the slide 504 near the left end. Two sets of symmetrically distributed convex plate structures are provided on the lower side of the slide 504. A threaded through hole is provided at the center of the left convex plate of the slide 504, and a through hole is provided at the center of the right convex plate of the slide 504. The outer side of the threaded adjusting rod 505 is threadedly engaged with the threaded through hole of the convex plate of the slide 504. The guide rod 506 is inserted into the through hole of the convex plate of the slide 504. During the process of the adjusting knob 503 driving the threaded adjusting rod 505 to rotate, the threaded adjusting rod 505 drives the slide 504 to slide back and forth along the guide rod 506, so that the cutting workpiece 507 clamped on the upper side of the slide 504 moves back and forth synchronously, and the cutting position of the cutting workpiece 507 is quickly adjusted.

[0025] In this embodiment, the left side of the clamping plate 508 is provided with a through-hole groove, and the lower side of the clamping plate 508 is provided with an inverted T-shaped protrusion structure. The top of the T-shaped protrusion of the clamping plate 508 is embedded in the long through groove of the slide block 504, so that the extension rod of the hydraulic cylinder 502 drives the clamping plate 508 to move to the right along the long through groove of the slide block 504, so that the clamping plate 508, together with the baffle 512, stably contacts and clamps the workpiece 507 to be cut.

[0026] In this embodiment, the lifting frame 510 has an L-shaped structure. A protruding plate is provided on the right side of the L-shaped structure near the top. The upper side of the protruding plate has a through hole. The guide post 509 is inserted into the through hole of the protruding plate of the lifting frame 510. The upper side of the bottom of the L-shaped structure of the lifting frame 510 is a sloping structure. The bottom end of the T-shaped protruding plate of the clamping plate 508 is attached to the sloping structure of the lifting frame 510. During the process of the clamping plate 508 moving to the right to clamp the workpiece, the bottom end of the T-shaped protruding plate of the clamping plate 508 pushes the sloping structure of the lifting frame 510, so that the lifting frame 510 moves downward synchronously along the guide post 509. The lifting frame 510 drives the limiting plate 513 to press down on the upper side of the cutting workpiece 507. The limiting plate 513, together with the upper side of the slide 504, presses and clamps the cutting workpiece 507 from top to bottom, avoiding the cutting workpiece 507 from flipping and shifting during the downward cutting process.

[0027] In this embodiment, the right side of the limiting plate 513 is provided with a protrusion, and the center of the upper side of the protrusion is provided with a threaded through hole. The threaded rotating rod 516 is engaged with the threaded through hole of the protrusion of the limiting plate 513. The protrusion of the limiting plate 513 is embedded in the rectangular through groove of the lifting frame 510. The front and rear sides of the protrusion of the limiting plate 513 are respectively attached to the front and rear groove walls of the rectangular through groove of the lifting frame 510. During the process of the lifting knob 511 driving the threaded rotating rod 516 to rotate, the threaded rotating rod 516 synchronously drives the limiting plate 513 to move up and down along the rectangular through groove of the lifting frame 510, so that the limiting plate 513 can flexibly adjust the downward clamping position according to the height of the workpiece 507 being cut, so that the limiting plate 513 can be used to fix and clamp workpieces of different heights.

[0028] In this embodiment, the top end of the spring 514 is welded to the lower side of the convex plate of the lifting frame 510, and the bottom end of the spring 514 is welded to the upper side of the slide block 504. When the extension rod of the hydraulic cylinder 502 drives the clamping plate 508 to move to the left, the spring 514 causes the lifting frame 510 to drive the limiting plate 513 to move upward along the guide post 509 through its own elastic force. During the process of releasing the workpiece 507 left and right, the limiting plate 513 automatically releases the workpiece 507 up and down, making the release operation of the workpiece 507 faster and quicker.

[0029] The specific usage and function of this embodiment are as follows:

[0030] When cutting workpiece 507, this invention first places the workpiece on the upper side of slide 504, then manually rotates lifting knob 511. Lifting knob 511 drives threaded rod 516 to rotate. Since the outer thread of threaded rod 516 is engaged with the protruding threaded through hole of limiting plate 513, threaded rod 516 drives limiting plate 513 to move up and down along the rectangular through groove of lifting frame 510 according to the height of workpiece 507. This ensures that when clamping plate 508 and baffle 512 clamp workpiece 507 left and right, the lower side of limiting plate 513 is in contact with the cutting surface. The upper side of workpiece 507 is cut, and then the control machine 2 controls the hydraulic oil supply station 3 to start via the wire. The hydraulic oil supply station 3 supplies oil to the hydraulic cylinder 502 through the oil pipe. At this time, the extension rod of the hydraulic cylinder 502 pushes the T-shaped convex plate structure of the clamping plate 508 to move to the right. The bottom end of the T-shaped convex plate structure of the clamping plate 508 pushes the inclined structure of the lifting frame 510, so that the lifting frame 510 overcomes the elastic force of the spring 514 and moves vertically downward along the guide post 509. The lifting frame 510 drives the limiting plate 513 to move downward synchronously until the limiting plate 513 contacts the upper side of the cutting workpiece 507. At this time, the clamping plate 508 cooperates with the stop. Plate 512 clamps the workpiece 507 from left to right, while limit plate 513, in conjunction with slide block 504, clamps the workpiece 507 from top to bottom. Then, manually rotating adjustment knob 503 causes slide block 504, which is engaged with the outer side of threaded adjustment rod 505, to move back and forth along guide rod 506, aligning the cutting position of workpiece 507 with the saw blade of band saw 4. Then, control unit 2 starts band saw 4 via wire, and the operator holds band saw 4 and performs a downward and flipping motion. The saw blade of band saw 4 cuts workpiece 507 until it is completely cut. After cutting, the control unit 2 controls the band saw 4 to stop operating via a wire. The control unit 2 then controls the hydraulic oil supply station 3 to start via a wire. The hydraulic oil supply station 3 controls the extension rod of the hydraulic cylinder 502 to move the clamping plate 508 to the left and disengage it from the left side of the workpiece 507. At this time, the spring 514 drives the lifting frame 510 to move upward along the guide column 509 through its own elastic force. The lifting frame 510 then drives the limit plate 513 to rise synchronously and disengage from the upper side of the workpiece 507, thereby completing the rapid release of the workpiece 507. Then, the workpiece 507 can be removed from the slide 504.

[0031] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies, and any method that achieves the desired effect can be implemented. The control unit 2, hydraulic oil supply station 3, band saw 4, and hydraulic cylinder 502 mentioned above are all common market components. Upon purchase and use, simply connect them according to the instruction manual provided; therefore, further details are omitted here.
