Description

Technical Field

[0001] The present invention relates to the technical field of fixing devices, and in particular to a metal raw material cutting and fixing device and a processing method thereof. Background Art

[0002] A bench vise is a tool widely used in machining, metal cutting, assembly and other operations to fix and stabilize the workpiece. A bench vise is usually composed of a movable jaw, a fixed jaw, a base and a screw. By rotating the screw, the distance between the movable jaw and the fixed jaw can be easily adjusted to accommodate workpieces of different sizes.

[0003] When a metal material is fixed by a fixing device, a fixed jaw and a movable jaw are used to clamp the metal material, thereby fixing the metal material. However, when clamping a special-shaped metal material, there are only two opposing directions of force to fix the metal material. The metal material can easily be separated from the clamping of the movable jaw and the fixed jaw due to reasons such as small contact area and friction force, which makes it inconvenient to perform normal cutting processing on the metal material. Summary of the invention

[0004] The present invention proposes a metal material cutting and fixing device and a processing method thereof to solve the problem that when clamping a special-shaped metal material, only two opposing directions of force are used to fix the metal material, and the metal material is easily separated from the clamping of the movable jaw and the fixed jaw, making it inconvenient to cut and process the metal material normally.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a metal raw material cutting and fixing device and a processing method thereof, comprising a base, the top of the base is fixedly connected to an operating table, one side of the top of the operating table is fixedly connected to a fixed jaw, one side of the fixed jaw is provided with a movable jaw, one end of the movable jaw is slidably connected to the inner wall of the operating table, the inner wall of the operating table is rotatably connected to a screw rod, the outer surface of the screw rod is threadedly connected to the inner wall of the movable jaw, one end of the screw rod passes through the inner wall of the operating table and is fixedly connected to a rotating rod, the tops of the fixed jaw and the movable jaw are An auxiliary device is provided, which includes two slide rails, the bottoms of the two slide rails are fixedly connected to the tops of the fixed jaw and the movable jaw respectively, the outer surfaces of the slide rails are slidably connected with a slider, one side of the slider is fixedly connected with a sleeve, the inner wall of the sleeve is slidably connected with a pressure block, the top of one side of the pressure block is fixedly connected with a round hole block, the inner wall of the round hole block is slidably connected with a threaded rod, one end of the threaded rod is fixedly connected to the top of the slider, the outer surface of the threaded rod is threadedly connected with a nut, the nut is arranged on the top of the slider, and an adjusting device is provided at the bottom of the base.

[0006] The effect achieved by the above-mentioned components is: after using the movable jaws and the fixed jaws to fix the metal material, push the slider to slide on the outer surface of the slide rail until the slider reaches a suitable position, and then rotate the nut to make the nut move downward on the outer surface of the threaded rod. When the nut moves downward, it will squeeze the circular hole block and drive the pressure block connected to the circular hole block to slide on the inner wall of the sleeve until the bottom of the pressure block abuts against the outer surface of the metal material, which can effectively increase the clamping contact area and friction force of the metal material while providing two forces different from the horizontal direction to limit the metal material, which is beneficial to prevent the metal material from escaping from the clamping of the movable jaws and the fixed jaws, and facilitate the normal cutting processing of the metal material.

[0007] Preferably, a gasket is fixedly connected to the bottom of the nut, the gasket is made of rubber, and the outer surface of the threaded rod is inserted into the inner wall of the gasket.

[0008] The effect achieved by the above components is: by setting a gasket, instead of one side of the nut abutting against the top of the circular hole block, the friction between the nut and the circular hole block can be increased, which is beneficial to prevent the nut from loosening due to squeezing the circular hole block.

[0009] Preferably, a first spring is sleeved on the outer surface of the threaded rod, one end of the first spring is fixedly connected to the bottom of the circular hole block, and the other end of the first spring is fixedly connected to the top of the sliding block.

[0010] The effect achieved by the above components is: by setting the first spring, when the nut drives the round hole block to slide downward on the outer surface of the threaded rod, the first spring will be squeezed to cause the first spring to deform, and when the nut is rotated to make the nut move away from the round hole block, the first spring will reset and drive the pressure block to slide upward on the inner wall of the sleeve, so that the pressure block enters the inner wall of the sleeve until the height of all components at the bottom of the pressure block is higher than the top of the fixed jaw and the movable jaw, so that it is convenient to slide the slider to both sides of the operating table, and then it is convenient to install and remove the metal material.

[0012] The effect achieved by the above components is: by setting up a plurality of rubber blocks, one side of the pressing block can be replaced to abut against the outer surface of the metal original material, thereby increasing the friction between the pressing block and the metal original material; at the same time, when the metal original material squeezes the rubber block, the rubber block squeezes the second spring, causing the second spring to deform and drive the limiting rod to enter the inner wall of the pressing block; even if the outer surface of the metal original material is uneven, more rubber blocks can be made to contact the metal original material as much as possible, thereby increasing the contact area between the pressing block and the metal original material.

[0013] Preferably, one end of the threaded rod is fixedly connected to a first stopper, and one end of the slide rail is fixedly connected to a second stopper.

[0014] The effect achieved by the above components is: by setting the first stopper and the second stopper, one end of the threaded rod and one end of the slide rail can be blocked respectively, which is helpful to prevent the problem of the nut being separated from the threaded rod and the slider being separated from the slide rail due to misoperation.

[0015] Preferably, the adjusting device comprises four round rods, one ends of the four round rods are evenly and fixedly connected to the bottom of the base, the outer surface of the round rod is slidably connected to a cylinder, one end of the cylinder is fixedly connected to an auxiliary block, the inner wall of the auxiliary block is provided with rollers, the middle part of the bottom of the base is fixedly connected to a support rod, the bottom of the support rod is fixedly connected to a bottom plate, the bottom of the bottom plate is evenly provided with grooves, and the outer surfaces of the four cylinders are fixedly connected to the same connecting frame.

When the bottom of the roller exceeds the bottom of the bottom plate by a certain distance, the roller can contact the ground, and then it is convenient to push the fixing device on the ground through the roller, which is convenient for transferring the fixing device. At the same time, when the bottom plate exceeds the bottom of the roller by a certain distance, the bottom plate will contact the ground instead of the roller, so as to facilitate the positioning of the fixing device, which is beneficial to prevent the fixing device from shifting when cutting metal.

[0017] Preferably, a threaded pin is threadedly inserted into the inner wall of the cylinder, and one end of the threaded pin abuts against the outer surface of the round rod.

[0018] The effect achieved by the above components is: by setting a threaded pin and rotating the threaded pin so that one end of the threaded pin abuts against the outer surface of the round rod, the round rod and the cylinder can be fixed, and then the height of the roller can be fixed.

[0019] Preferably, one end of the threaded pin is fixedly connected to an operating block, and a protrusion is provided on the outer surface of the operating block.

[0020] The effect achieved by the above components is: by setting the operating block, rotating the operating block can drive the threaded pin to rotate, and at the same time, the outer surface of the operating block is provided with a protrusion, which can effectively increase the friction force of the outer surface of the operating block and has an anti-slip effect when rotating the operating block.

The outer surface of the threaded rod 26 is inserted into the inner wall of the gasket 29. By setting the gasket 29, one side of the nut 27 is replaced by the top of the circular hole block 25, which can increase the friction between the nut 27 and the circular hole block 25, thereby preventing the nut 27 from squeezing the circular hole block 25 and causing it to loosen; the outer surface of the threaded rod 26 is sleeved with a first spring 210, one end of the first spring 210 is fixedly connected to the bottom of the circular hole block 25, and the other end of the first spring 210 is fixedly connected to the top of the slider 21. By setting the first spring 21 0, when the nut 27 drives the round hole block 25 to slide downward on the outer surface of the threaded rod 26, the first spring 210 will be squeezed, causing the first spring 210 to deform.

By providing a plurality of rubber blocks 282, one side of the pressing block 24 can be replaced to abut against the outer surface of the metal raw material, thereby increasing the friction between the pressing block 24 and the metal raw material. At the same time, when the metal raw material squeezes the rubber block 282, the rubber block 2 82 will squeeze the second spring 281, causing the second spring 281 to deform and drive the limiting rod 283 to enter the inner wall of the pressure block 24, so that even if the outer surface of the metal material is uneven, more rubber blocks 282 can be made to contact the metal material as much as possible, thereby increasing the contact area between the pressure block 24 and the metal material; one end of the threaded rod 26 is fixedly connected to the first stop block 211, and one end of the slide rail 22 is fixedly connected to the second stop block 212. By setting the first stop block 211 and the second stop block 212, one end of the threaded rod 26 and one end of the slide rail 22 can be blocked respectively, which is beneficial to prevent the problem of the nut 27 being separated from the threaded rod 26 and the slider 21 being separated from the slide rail 22 due to misoperation.

[0028] Reference Figure 5 and Figure 6As shown, the adjusting device 3 includes four round rods 31, one end of the four round rods 31 is evenly fixedly connected to the bottom of the base 1, the outer surface of the round rod 31 is slidably connected to a cylinder 32, one end of the cylinder 32 is fixedly connected to an auxiliary block 33, the inner wall of the auxiliary block 33 is provided with a roller 34, the middle part of the bottom of the base 1 is fixedly connected to a support rod 35, the bottom of the support rod 35 is fixedly connected to a bottom plate 36, the bottom of the bottom plate 36 is evenly provided with grooves, the outer surfaces of the four cylinders 32 are fixedly connected to the same connecting frame 37, by setting the connecting frame 37, the connecting frame 37 connects the four cylinders 32 as a whole, and pushes The cylinder 32 slides on the outer surface of the round rod 31, and the cylinder 32 drives the roller 34 connected to the auxiliary block 33 to move synchronously in the vertical direction.

At the same time, when the bottom plate 36 exceeds the bottom of the roller 34 by a certain distance, the bottom plate 36 will contact the ground instead of the roller 34, so as to facilitate the positioning of the fixing device, which is beneficial to prevent the fixing device from shifting when cutting metal.

[0029] Reference Figure 5 and Figure 6 As shown, a threaded pin 38 is inserted into the inner wall of the cylinder 32, and one end of the threaded pin 38 abuts against the outer surface of the round rod 31. By setting the threaded pin 38 and rotating the threaded pin 38 so that one end of the threaded pin 38 abuts against the outer surface of the round rod 31, the round rod 31 and the cylinder 32 can be fixed, and then the height of the roller 34 can be fixed; one end of the threaded pin 38 is fixedly connected to an operating block 39, and a protrusion is provided on the outer surface of the operating block 39.

[0030] Working principle: When it is necessary to fix the metal material, first, rotate the nut 27 so that the nut 27 moves away from the circular hole block 25 until it abuts against one side of the first stopper 211. Then, the first spring 210 will reset due to the loss of external force and drive the pressure block 24 to slide upward on the inner wall of the sleeve 23, so that the pressure block 24 enters the inner wall of the sleeve 23, until the height of all parts at the bottom of the pressure block 24 is higher than the top of the fixed jaw 5 and the movable jaw 6, and then push the slider 21 to move on the slide rail 22, so that the slider 21 is close to the second stopper 212; then, place the metal material between the fixed jaw 5 and the movable jaw 6, and rotate the rotating rod 8 to drive the screw rod 7 to rotate, and the screw rod 7 The movable jaw 6 will be driven to move toward the fixed jaw 5 until the fixed jaw 5 and the movable jaw 6 completely clamp the metal material; finally, the nut 27 is rotated so that the nut 27 moves downward on the outer surface of the threaded rod 26. When the nut 27 moves downward, it will squeeze the circular hole block 25 and drive the pressing block 24 connected to the circular hole block 25 to slide on the inner wall of the sleeve 23 until the rubber block 282 at the bottom of the pressing block 24 abuts against the outer surface of the metal material. The rubber block 282 can replace one side of the pressing block 24 to abut against the outer surface of the metal material, thereby increasing the friction between the pressing block 24 and the metal material. At the same time, when the metal material squeezes the rubber block 282, the rubber block 2 The second spring 281 is squeezed by the rubber block 282, so that the second spring 281 is deformed, and the limiting rod 283 is driven to enter the inner wall of the pressing block 24, so that even if the outer surface of the metal material is uneven, more rubber blocks 282 can be made to contact the metal material as much as possible, thereby increasing the contact area between the pressing block 24 and the metal material, thereby preventing the metal material from being separated from the clamping of the movable jaw 6 and the fixed jaw 5, and facilitating the normal cutting of the metal material; the cylinder 32 is pushed to slide on the outer surface of the round rod 31, and the cylinder 32 will drive the roller 34 connected to the auxiliary block 33 to move synchronously in the vertical direction. When the bottom of the roller 34 exceeds the bottom of the bottom plate 36, the bottom of the roller 34 is moved synchronously. The roller 34 can contact the ground after the bottom plate 36 exceeds the bottom of the roller 34 by a certain distance, and the bottom plate 36 will contact the ground instead of the roller 34, and the threaded pin 38 will be rotated to fix the height of the roller 34, so as to facilitate the positioning of the fixing device, which is beneficial to prevent the fixing device from shifting when cutting metal.
