Description

Technical Field

[0001] This utility model relates to the field of band saw technology, specifically to a multi-directional clamping and positioning device for a band saw. Background Technology

[0002] Tungsten-molybdenum powder sintered blocks are brittle materials, making them difficult to cut. Existing cutting methods generally involve manual sawing, which is not only labor-intensive but also inefficient and wasteful of materials. Patent CN201922412412.7 discloses a band saw for cutting tungsten-molybdenum powder sintered blocks, characterized by high sawing efficiency, high sawing accuracy, and low material waste. However, during the use of the band saw, the clamps typically clamp and position the workpiece from both sides. If the workpiece is lifted during sawing as the saw blade moves, it can easily affect the sawing process. Therefore, we propose a multi-directional clamping and positioning device for the band saw. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a multi-directional clamping and positioning device for band saws.

[0004] The technical solution adopted by this utility model to solve its technical problem is a multi-directional clamping and positioning device for a band saw, including a machine base. The top side surface of the machine base is provided with a band saw body, and a slide table for support is slidably installed on the top surface of the machine base via an electric slide rail. There are two sets of slide tables. The top surface of the slide table is fitted with a support rail seat by bolts, and a sliding plate for limiting is slidably installed in the rail seat. A slider for adjustment is slidably installed on the outer wall surface of the slide plate, and a support protrusion is integrally constructed at one end of the slider located outside the slide plate. A pressure plate that fits with the protrusion is snapped onto the outer periphery of the slider, and a rotating rod that is screwed into the top surface of the pressure plate and connected to the protrusion is screwed on. There are two sets of rotating rods.

[0005] The outer wall surface of the rail seat is bolted with a stop for limiting the position. A lead screw is rotatably installed between the stop and the rail seat and on the inner side of the slide plate. A worm gear, which is driven by the lead screw, is rotatably installed on the inner side of the stop and the inner side of the slide plate. A reducer is installed on the inner side of the stop and the inner side of the slide plate. A worm gear that meshes with the worm gear is installed at the power output end of the reducer. A rotating seat, which is driven by the reducer, is rotatably installed on the outer wall surface of the stop and the outer wall surface of the slide plate.

[0006] By adopting the above technical solution, when using a band saw to cut a workpiece, the workpiece can be conveniently placed on the rail seats on the surfaces of the two sets of slide tables. The sliding slide on the rail seats can limit and clamp the two sides of the workpiece. Then, the sliding slider on the surface of the slide can drive the pressure plate to limit and press the workpiece. This allows for multi-directional positioning of the workpiece to be cut, which improves the stability of the workpiece during sawing. At the same time, simply unscrewing the screw on the top of the pressure plate can separate the pressure plate from the slider, making it easy to replace the pressure plate. This allows the pressure plate to stably press and limit the workpiece and improves the versatility of the band saw's functions.

[0007] When it is necessary to clamp the workpiece on both sides using the slide plate, the outer rotating seat of the stop can be rotated. The rotating seat then drives the reducer inside the stop to operate and drive the worm to rotate. This allows the worm to mesh with the worm wheel and drive the worm wheel to rotate. The worm wheel then drives the lead screw inside the rail seat to rotate, allowing the lead screw to screw into the slide plate. This allows the slide plate to slide along the groove inside the rail seat. The movement of the slide plates on multiple rail seats facilitates the limiting and clamping of the workpiece. Then, rotating the outer rotating seat of the slide plate again causes the reducer inside the slide plate to operate and drive the worm to rotate. This causes the worm to mesh with the worm wheel and drive the worm wheel to rotate. The worm wheel then drives the lead screw to rotate and screw into the slider. This allows the slider to drive the pressure plate to limit and clamp the top of the workpiece, thereby improving the effect of limiting the workpiece. Finally, the operation of the electric slide rail on the machine facilitates the movement of the top of the two sets of slides and allows the band saw body to operate to facilitate sawing of the workpiece.

[0008] Specifically, the top surface of the rail seat has a groove that fits the sliding plate, and there are multiple sets of grooves.

[0009] By adopting the above technical solution, the groove on the surface of the rail seat and the protrusion on the bottom of the slide plate fit together, which helps to improve the stability of the slide plate when sliding on the surface of the rail seat, so that the slide plate can more stably limit and clamp the workpiece.

[0010] Specifically, the outer wall surface of the slider is integrally constructed with protrusions that fit with the pressure plate, and there are multiple sets of protrusions.

[0011] By adopting the above technical solution, the convex strips on the surface of the slider can improve the stability when the pressure plate is connected to it, so that the pressure plate can more stably limit the workpiece.

[0012] Specifically, the protruding strip and the pressure plate are each equipped with a magnetically connected magnetic block, and there are multiple sets of magnetic blocks.

[0013] By adopting the above technical solution, the magnetic blocks between the protrusion and the pressure plate can be magnetically connected to each other, which facilitates the provision of certain limiting performance when the pressure plate and the protrusion are engaged with each other. Then, it is convenient to take out the rotating rod and screw it into the hole on the top of the pressure plate, which facilitates the fixation between the pressure plate and the slider.

[0014] Specifically, the bottom surface of the pressure plate is provided with a pad for anti-slip purposes.

[0015] By adopting the above technical solution, the anti-slip rubber pad can improve the stability of the pressure plate when pressing the workpiece, and reduce the friction between the pressure plate and the pressed object that causes scratches.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of slide table, rail base, slide plate, slider, protrusion, pressure plate and rotary rod, allows the workpiece to be conveniently placed on the rail base on the surface of the two sets of slide tables when sawing workpieces using a band saw. The sliding slide plate on the rail base can limit and clamp the two sides of the workpiece. Then, the slider sliding on the surface of the slide plate can drive the pressure plate to limit and press the workpiece. This allows for multi-directional positioning of the workpiece to be sawed, which improves the stability of the workpiece during sawing. At the same time, the pressure plate and the slider can be separated by simply unscrewing the rotary rod on the top of the pressure plate, which facilitates the replacement of the pressure plate. This allows the pressure plate to stably press and limit the workpiece and improves the versatility of the band saw's functions.

[0018] 2. The technical solution of this application, through the design of the band saw body, stop, lead screw, worm gear, reducer, worm, and rotary seat, allows the rotary seat on the outer side of the stop to rotate when the workpiece needs to be clamped on both sides using the slide plate. The rotary seat then drives the reducer inside the stop to operate, which in turn drives the worm to rotate. This allows the worm to mesh with the worm gear and rotate, which in turn drives the lead screw inside the guide seat to rotate. This allows the lead screw to engage with the slide plate, enabling the slide plate to slide along the groove inside the guide seat. The sliding plates on multiple sets of rails facilitate the clamping and limiting of the workpiece. Then, rotating the outer rotating seat of the sliding plate causes the reducer inside the sliding plate to operate and drive the worm gear to rotate. The worm gear meshes with the worm wheel and drives the worm wheel to rotate. Subsequently, the worm wheel drives the lead screw to rotate and engages with the slider. This allows the slider to drive the pressure plate to limit and clamp the top of the workpiece, thereby improving the effect of limiting the workpiece. Then, the operation of the electric slide rail on the machine facilitates the displacement of the top of the two sets of slides and enables the band saw body to operate to facilitate sawing of the workpiece.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a multi-directional clamping and positioning device for a band saw, including a machine base 1. A band saw body 2 is provided on one side of the top of the machine base 1. A slide table 3 for support is slidably mounted on the top surface of the machine base 1 via an electric slide rail. There are two sets of slide tables 3. A support rail seat 4 is bolted to the top surface of the slide table 3. A limiting slide plate 5 is slidably mounted inside the rail seat 4. An adjustable slider 6 is slidably mounted on the outer wall surface of the slide plate 5. A supporting protrusion 7 is integrally constructed at one end of the slider 6 located outside the slide plate 5. A pressure plate 8 that engages with the protrusion 7 is engaged with the outer periphery of the slider 6. The top surface of the 8 is screwed with a rotating rod 9 that is screwed to the protrusion 7, and there are two sets of rotating rods 9; the outer wall surface of the rail seat 4 is bolted with a stop 10 for limiting, and a lead screw 11 is rotatably installed between the stop 10 and the rail seat 4 and on the inner side of the slide plate 5. A worm gear 12 that is driven by the lead screw 11 is rotatably installed on the inner side of the stop 10 and the inner side of the slide plate 5. A reducer 13 is installed on the inner side of the stop 10 and the inner side of the slide plate 5. A worm 14 that meshes with the worm gear 12 is installed at the power output end of the reducer 13, and a rotating seat 15 that is driven by the reducer 13 is rotatably installed on the outer wall surface of the stop 10 and the outer wall surface of the slide plate 5.

[0026] When using a band saw to cut a workpiece, the workpiece can be easily placed on the rail seats 4 on the surfaces of the two sets of slide tables 3. The sliding plate 5 on the moving rail seat 4 can limit and clamp the two sides of the workpiece. Then, the sliding slider 6 on the surface of the sliding plate 5 can drive the pressure plate 8 to limit and press the workpiece. This allows for multi-directional positioning of the workpiece to be cut, which helps to improve the stability of the workpiece during sawing. At the same time, simply unscrewing the screw rod 9 on the top of the pressure plate 8 can separate the pressure plate 8 from the slider 6, making it easy to replace the pressure plate 8. This allows the pressure plate 8 to stably press and limit the workpiece and improves the versatility of the band saw's functions.

[0027] When it is necessary to clamp the workpiece on both sides using the slide plate 5, the rotating seat 15 on the outer side of the stop 10 can be rotated. The rotating seat 15 then drives the reducer 13 inside the stop 10 to operate and drive the worm 14 to rotate, so that the worm 14 can mesh with the worm wheel 12 and drive the worm wheel 12 to rotate. Then the worm wheel 12 can easily drive the lead screw 11 inside the rail seat 4 to rotate, so that the lead screw 11 can be screwed with the slide plate 5, allowing the slide plate 5 to slide along the groove inside the rail seat 4. The displacement of the slide plates 5 on multiple sets of rail seats 4 facilitates the workpiece. After clamping and limiting, the rotating seat 15 on the outside of the slide plate 5 is rotated, which causes the reducer 13 inside the slide plate 5 to operate and drive the worm gear 14 to rotate. The worm gear 14 meshes with the worm wheel 12 and drives the worm wheel 12 to rotate. Then the worm wheel 12 drives the lead screw 11 to rotate and engages with the slider 6. This allows the slider 6 to drive the pressure plate 8 to limit and press the top of the workpiece, thereby improving the effect of limiting the workpiece. Then the electric slide rail on the machine base 1 can easily drive the top displacement of the two sets of slide tables 3 and make the band saw body 2 easy to cut the workpiece.

[0028] like Figure 1 As shown, the top surface of the rail base 4 has a groove 16 that fits into the slide plate 5, and there are multiple sets of grooves 16.

[0029] When in use, the groove 16 on the surface of the rail seat 4 and the protrusion at the bottom of the slide plate 5 fit together, which helps to improve the stability of the slide plate 5 when it slides on the surface of the rail seat 4, so that the slide plate 5 can more stably limit and clamp the workpiece.

[0030] like Figure 3 As shown, the outer wall surface of the slider 6 is integrally constructed with a protrusion 17 that matches the pressure plate 8, and there are multiple sets of protrusions 17.

[0031] When in use, the protrusions 17 on the surface of the slider 6 can improve the stability of the pressure plate 8 when it is connected to it, so that the pressure plate 8 can more stably limit the workpiece.

[0032] like Figure 3As shown, the protruding strip 17 and the pressure plate 8 are each equipped with a magnetically connected magnetic block 18, and there are multiple sets of magnetic blocks 18.

[0033] In use, the magnetic block 18 between the protrusion 17 and the pressure plate 8 can be magnetically connected to each other, which provides a certain limiting performance when the pressure plate 8 and the protrusion 7 are engaged with each other. Then, it is convenient to take out the rotating rod 9 and screw it into the hole on the top of the pressure plate 8, which facilitates the fixation between the pressure plate 8 and the slider 6.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, a pad 19 for anti-slip is provided on the bottom surface of the pressure plate 8.

[0035] When in use, the anti-slip rubber pad 19 can improve the stability of the pressure plate 8 when pressing the workpiece, and reduce the friction between the pressure plate 8 and the pressed object, which can cause scratches.

[0036] The working principle and usage process of this utility model are as follows: First, install the corresponding structural components in suitable positions. When using the band saw to cut the workpiece, the workpiece can be easily placed on the rail seats 4 on the surfaces of the two sets of slide tables 3. Moving the sliding plate 5 on the rail seat 4 can limit and clamp the two sides of the workpiece. Then, moving the sliding block 6 on the surface of the sliding plate 5 can drive the pressure plate 8 to limit and clamp the workpiece, thereby enabling multi-directional positioning of the workpiece to be cut, improving the stability of the workpiece during sawing. Simultaneously, simply unscrewing the rotating rod 9 at the top of the pressure plate 8 allows the pressure plate 8 and the sliding block 6 to separate, facilitating the replacement of the pressure plate 8. This ensures that the pressure plate 8 can stably clamp and limit the workpiece, improving the versatility of the band saw's functions. Furthermore, when it is necessary to use the sliding plate 5 to clamp the two sides of the workpiece, the rotating seat 15 on the outer side of the stop 10 can be rotated. The rotating seat 15 then drives the reducer 13 inside the stop 10. The machine tool rotates the worm gear 14, causing it to mesh with the worm wheel 12 and rotate. The worm wheel 12 then rotates the lead screw 11 inside the rail seat 4, allowing the lead screw 11 to screw into the slide plate 5, enabling the slide plate 5 to slide along the groove inside the rail seat 4. The displacement of the slide plates 5 on multiple rail seats 4 facilitates the clamping and limiting of the workpiece. Then, the rotating seat 15 on the outside of the slide plate 5 rotates, causing the reducer 13 inside the slide plate 5 to operate and rotate the worm gear 14, causing the worm gear 14 to mesh with the worm wheel 12 and rotate. The worm wheel 12 then rotates the lead screw 11 and screws into the slider 6, allowing the slider 6 to drive the pressure plate 8 to clamp and limit the top of the workpiece, thereby improving the effect of limiting the workpiece. Finally, the operation of the electric slide rail on the machine tool 1 facilitates the displacement of the top of the two sets of slide tables 3, allowing the band saw body 2 to operate and facilitate sawing of the workpiece.
