A baffle-adjustable metal cutting machine

Abstract

This application discloses a baffle-adjustable metal cutting machine, relating to the field of cutting machines. It includes a base, a cutting component, a depth control component, and an angle control component. When adjusting the angle, simply rotating the gripper plate moves the extrusion column upwards to release the extrusion. Then, the fixed toothed ring is lifted by the protrusions on both sides of the fixed toothed ring, allowing the adjustment plate to be moved. When vibration during cutting causes the extrusion column to loosen its pressure on the abutment plate, the fixed toothed ring is limited by the action of the compression spring and the counterweight, thus preventing the abutment plate from rotating. When the vibration of the workpiece causes the threaded rod to loosen, resulting in axial movement of the threaded rod, the connecting sleeve moves the insertion plate synchronously. The movement of the insertion plate, through the toothed grooves on its outer surface, causes the limiting plate to move laterally. Under the action of the compression spring, the limiting plate is reset, thereby resetting the insertion plate. This achieves the counteracting of the vibration's effects and prevents loosening of the workpiece due to vibration during cutting.

Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a metal cutting machine with adjustable baffle. Background Technology

[0002] A metal cutting machine is a mechanical device used to cut metal materials. It utilizes rotating blades or grinding wheels to achieve precise cutting of metal materials. Metal cutting machines are widely used in industries such as metal processing, machinery manufacturing, aerospace, automobile manufacturing, shipbuilding, building structures, and metal decoration.

[0003] When cutting materials using a metal cutting machine, the workpiece is placed on the base and then pressed and fixed by the baffles on the base. The baffles on the base are mainly divided into two parts, including a depth control baffle and an angle control baffle, which clamp and fix the workpiece. Then, the cutting component is controlled to move closer to the workpiece, thereby achieving the cutting of the workpiece.

[0004] Since the working principle of a cutting machine is to cut the workpiece by rotating blades or grinding wheels, the workpiece will vibrate during the cutting process. The existing angle control baffle and depth control baffle are mainly fixed by the compression and locking of bolts. However, the baffle is prone to loosening after long-term cutting, which will cause the workpiece to shake during cutting. This will not only cause the workpiece to fail to be processed, but may also cause injury to the worker, making it inconvenient to use. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This utility model provides a metal cutting machine with an adjustable baffle. It has the following advantages:

When vibration occurs during cutting, causing the extrusion column to loosen its compression lock on the abutment plate, the fixed toothed ring is limited by the action of the compression spring and the counterweight, thus preventing the abutment plate from rotating and avoiding workpiece misalignment caused by the adjusting plate loosening during cutting.

[0020] 2. When the vibration of the workpiece causes the threaded rod to loosen and move axially, the connecting sleeve moves the plug plate synchronously. The movement of the plug plate drives the limit plate to move laterally through the toothed groove on the outer surface. Under the action of the compression spring, the limit plate is reset, thereby resetting the plug plate. This achieves the effect of vibration and avoids loosening of the workpiece due to vibration during the cutting process. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a baffle-adjustable metal cutting machine, including a base 1, a cutting component 2 provided on the upper surface of the base 1, a depth control component 3 provided on the upper surface of the base 1, and an angle control component 4 provided on the upper surface of the base 1.

[0030] The depth control component 3 includes a support base 302 fixedly installed on the upper surface of the base 1. A threaded rod 301 is inserted inside the support base 302. A connecting post 308 is movably connected to one end of the threaded rod 301 near the cutting component 2. An abutment plate 307 is movably connected to the outer surface of the connecting post 308. A connecting sleeve 309 is fixedly connected to one side of the connecting post 308 near the support base 302. Insertion plates 306 are provided on both sides of the connecting sleeve 309. Two fixing seats 304 are fixedly connected to the upper surface of the base 1. A limit plate 305 is slidably provided on the upper surface of the fixing seat 304. A compression spring 303 is fixedly connected between the limit plate 305 and the fixing seat 304.

[0031] Specifically, the top of the support base 302 has a groove that mates with the threaded rod 301. A locking block 310 is hinged to the top of the inner wall of the groove. The outer surface of the locking block 310 has a threaded groove that mates with the threaded rod 301. A torsion spring is provided at the hinge point between the locking block 310 and the support base 302. The upper surface of the base 1 has a rectangular groove that mates with the connecting post 308. The bottom end of the connecting post 308 passes through the interior of the abutment plate 307 and mates with the rectangular groove. The threaded rod 301 passes through the interior of the groove and is pressed and locked by the locking block 310 hinged to the top of the support base 302. Under the action of the torsion spring... The lower engaging block 310 engages with the threaded rod 301 through the threaded groove on its outer surface. This allows the threaded rod 301 to be pushed open, which in turn drives the abutment plate 307 on the outer surface of the connecting post 308 to abut and limit the workpiece. After releasing the engaging block 310, the threaded rod 301 can be rotated to engage with the engaging block 310, allowing the moving threaded rod 301 to further compress the connecting post 308, thereby fixing the workpiece. The engagement of the rectangular groove with the connecting post 308 prevents the connecting post 308 from rotating with the threaded rod 301.

[0032] Specifically, the connecting sleeve 309 has a through hole with a diameter larger than that of the threaded rod 301. One end of the threaded rod 301 passes through the through hole and is movably connected to the inside of the connecting post 308. The through hole ensures that the connecting sleeve 309 does not affect the rotation of the threaded rod 301.

[0033] Specifically, the plug plate 306 has a limiting protrusion on the side near the connecting sleeve 309, and several slots that mate with the limiting protrusion are provided on both sides of the connecting sleeve. The outer surfaces of the plug plate 306 and the limiting plate 305 are provided with mutually mating toothed grooves. By cooperating with the limiting protrusion and the slots, the plug plate 306 is limited, and the plug plate 306 can be pulled out of the connecting sleeve and reinstalled, which facilitates the cooperation between the plug plate 306 and the limiting plate 305.

[0034] Specifically, two insert rods 311 are fixedly connected to one end of the limiting plate 305 near the fixed base 304. The fixed base 304 has an insertion hole that mates with the insert rods 311. The lower surface of the limiting plate 305 is provided with a limiting protrusion. The outer surface of the fixed base 304 is provided with a limiting groove that mates with the limiting protrusion. Through the cooperation between the insert rods 311 and the insertion hole, and the cooperation between the limiting protrusion and the limiting groove, the movement of the limiting plate 305 is controlled, and the limiting plate 305 is prevented from shifting.

[0035] Furthermore, when the vibration of the workpiece causes the threaded rod 301 to loosen and move axially, the connecting sleeve 309 moves the insertion plate 306 synchronously. The movement of the insertion plate 306 then moves the limiting plate 305 laterally through the toothed grooves on its outer surface. Under the action of the compression spring 303, the limiting plate 305 is reset, thereby resetting the insertion plate 306. This achieves the effect of offsetting the vibration and avoids loosening of the workpiece due to vibration during the cutting process.

[0036] Example 2

[0037] Reference Figure 1 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The angle control component 4 includes a mounting rod 401 fixedly installed on the upper surface of the base 1. A rotating arm 403 is fixedly connected to the top end of the mounting rod 401. A limiting post 404 is fixedly connected to the lower surface of the rotating arm 403. An adjusting plate 408 is movably provided on the outer surface of the limiting post 404. A fixing toothed ring 410 is fixedly installed on the upper surface of the adjusting plate 408. A limiting toothed ring 411 is provided on the outer surface of the limiting post 404. A fixing disk 402 is fixedly connected to the outer surface of the limiting post 404. A compression spring 409 is provided between the limiting toothed ring 411 and the fixing disk 402.

[0038] Specifically, the lower surface of the limiting toothed ring 411 and the upper surface of the fixing toothed ring 410 are both provided with mutually cooperating teeth. Two protruding plates are fixedly connected to the outer surface of the limiting toothed ring 411. A counterweight 412 is fixedly connected to the upper surface of the limiting toothed ring 411. The upper surface of the counterweight 412 is fixedly connected to the bottom end of the compression spring 409. The top end of the compression spring 409 is fixedly connected to the lower surface of the fixed disk 402. Through holes that cooperate with the limiting post 404 are opened on the upper surface of the base 1 and inside the fixing toothed ring 410. Adjusting plate The limiting adjustment plate 408 rotates through the cooperation of the limiting toothed ring 411 and the fixed toothed ring 410. The bottom end of the limiting post 404 passes through the through hole inside the fixed toothed ring 410 and the adjustment plate 408, thereby limiting the rotation of the mounting rod 401, the rotating arm 403 and the limiting post 404. The limiting post 404 serves as the circle for the rotation of the adjustment plate 408. The counterweight 412 further increases the downward pressure of the limiting toothed ring 411 on the fixed toothed ring 410, thereby preventing the limiting toothed ring 411 from disengaging from the fixed toothed ring 410.

[0039] Specifically, a screw 407 is inserted inside the adjusting plate 408. The bottom end of the screw 407 passes through the upper surface of the base 1 and is engaged with a nut. The top end of the screw 407 is fixedly connected to a pressing column 406. A handle 405 is installed on the top of the pressing column 406. An arc-shaped groove is opened inside the adjusting plate 408 to cooperate with the screw 407. Through the cooperation of the screw 407 and the nut, the pressing column 406 is driven to press the adjusting plate 408. The handle 405 controls the rotation of the screw 407. The outer surface of the adjusting plate 408 is provided with scale teeth at the edge of the arc-shaped groove. The setting of the arc-shaped groove makes it easy to observe the rotation angle of the adjusting plate 408.

[0040] Furthermore, by rotating the handle 405, the screw 407 is rotated by the pressing column 406, causing the pressing column 406 to release the pressing lock on the adjusting plate 408. Then, the protruding plate on the outer surface of the limiting tooth ring 411 pulls the limiting tooth ring 411 upward, thereby unlocking the fixed tooth ring 410. At this time, after rotating the adjusting plate 408 to the designated position, the limiting tooth ring 411 is released, thereby changing the angle of the adjusting plate 408. The limiting tooth ring 411 and the counterweight 412 are both provided with through holes that cooperate with the limiting column 404. The through holes inside the limiting tooth ring 411 and the counterweight 412 are provided with flat keys. The outer surface of the limiting column 404 is provided with a keyway that cooperates with the flat key, thereby preventing the limiting tooth ring 411 from rotating with the fixed tooth ring 410.

[0041] Working principle: When cutting a workpiece using a cutting machine, the angle control component 4 is adjusted to the required cutting angle. By rotating the handle 405, the screw 407 is rotated via the extrusion column 406, causing the extrusion column 406 to release its compression lock on the adjusting plate 408. Then, the protrusion plate on the outer surface of the limiting toothed ring 411 pulls the limiting toothed ring 411 upward, thereby unlocking the fixing toothed ring 410. At this time, after rotating the adjusting plate 408 to the designated position, the limiting toothed ring 411 is released, and the counterweight 412 and the compression spring 409... Under the action of the limiting toothed ring 411, it engages with the fixed toothed ring 410, and the handle 405 is rotated again. This causes the extrusion column 406 to press against the limiting abutment plate 307 through the engagement of the screw 407 and the nut. When vibration occurs during cutting, causing the extrusion column 406 to loosen its pressing lock on the abutment plate 307, the fixed toothed ring 410 is limited by the action of the compression spring 409 and the counterweight 412, thereby preventing the abutment plate 307 from rotating. After the angle adjustment is completed, the workpiece is placed on the base 1 and abuts against the abutment plate 307. At this time, the depth adjustment component is started by opening the latching block 3. 10. This pushes the threaded rod 301 to quickly move the abutment plate 307 on the outer surface of the connecting column 308 to abut against the outer surface of the workpiece. Then, the locking block 310 is released, and by rotating the threaded rod 301, the threaded rod 301 engages with the threaded groove on the outer surface of the locking block 310. This movement of the threaded rod 301 further compresses the connecting column 308, thereby fixing the workpiece. Then, the insertion plate 306 is inserted into the slot on the outer surface of the connecting sleeve 309 through the protrusion. After insertion, the insertion plate 306 engages with the toothed groove on the outer surface of the limiting plate 305, so that during the cutting process, the workpiece... When the vibration of the workpiece causes the threaded rod 301 to loosen and move axially, the connecting sleeve 309 moves the plug plate 306 synchronously. The movement of the plug plate 306 drives the limiting plate 305 to move laterally through the toothed groove on the outer surface. Under the action of the compression spring 303, the limiting plate 305 is reset, thereby driving the plug plate 306 to reset. This achieves the effect of vibration and avoids loosening caused by vibration during the workpiece cutting process. After the workpiece is fixed, it is cut by the cutting component 2, and the cutting of the metal workpiece is finally completed.
