Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to an adjustable milling machine fixture. Background Technology

[0002] A milling machine fixture is a tool used to machine planes, grooves, splines, and various shaped surfaces on parts, and is one of the most commonly used fixtures in machining. It mainly consists of a positioning device, a clamping device, a fixture body, connecting elements, and a tool setting element. During milling, due to the large cutting forces and the tendency to generate vibrations, milling machine fixtures need to possess high clamping force, rigidity, and strength.

[0003] In the prior art, such as the milling machine fixture disclosed in Chinese Patent Publication No. CN222002652U, there is a mounting box. Two moving blocks are slidably connected to the bottom inner wall of the mounting box. A rectangular hole is opened at the top of the mounting box. The two moving blocks extend through the rectangular hole to the top of the mounting box and are fixedly connected to a first clamping plate. A rectangular groove is opened at the top of the first clamping plate. A sliding plate is slidably connected through the rectangular groove. A second clamping plate is fixedly connected to the top of the sliding plate. A sliding block is slidably connected through the top of the mounting box. This utility model is simple to use. Turning the handle can drive the two first clamping plates to move closer together to clamp the workpiece. Gear grooves are provided to prevent the workpiece from slipping. The second clamping plate is an adjustable structure to increase the thickness that the first clamping plate can clamp. Pulling the plug rod can drive the support plate to rise. The support plate supports the workpiece and prevents the workpiece from slipping during processing. It is convenient to use and provides stable clamping.

[0004] In actual production, although this type of milling machine fixture can clamp the workpiece, during the milling process, it is necessary to process all angles of the workpiece surface. This type of milling machine fixture does not have an adjustment device, which means that the milling machine can only process a single angle of the workpiece surface. It is necessary to repeatedly remove the workpiece, adjust the angle, and then clamp the workpiece again with this type of milling machine fixture in order to achieve the goal of processing all angles of the workpiece surface. This increases the workload of the workers and results in poor performance of this device. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable milling machine fixture that has the effect of adjusting and clamping the workpiece.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable milling machine fixture, including a base, a machine tool fixedly connected to the upper surface of the base, a T-slot fixedly connected to the upper surface of the machine tool, a threaded hole opened inside the T-slot, a clamping plate arranged outside the T-slot, a motor fixedly connected inside the clamping plate, a rotating hole opened inside the clamping plate, a small gear disk arranged inside the clamping plate, the output end of the motor fixedly connected to the small gear disk, a large gear disk arranged inside the clamping plate, the small gear disk meshing with the large gear disk, a rotating rod fixedly connected to the outside of the large gear disk, an adjusting plate arranged outside the clamping plate, one end of the rotating rod penetrating into the rotating hole and fixedly connected to the adjusting plate, a vise fixedly connected to the upper surface of the adjusting plate, a pushing hole opened inside the vise, a hydraulic press fixedly connected to the outside of the vise, a clamping plate arranged inside the vise, the output end of the hydraulic press penetrating into the pushing hole and fixedly connected to the clamping plate.

[0007] By adopting the above technical solution, the worker fixes the clamping plate to the outside of the T-slot with studs, places the workpiece inside the vise, and then starts the hydraulic press. The hydraulic press output drives the clamping plate to move, and the clamping plate pushes the workpiece against the inner wall of the vise, thus clamping and fixing the workpiece. Then, the milling cutter begins to process the surface of the workpiece. When it is necessary to process a different angle of the upper surface of the fixed workpiece, the motor is started, and the motor starts to rotate. The output of the motor drives the small gear plate to rotate. Through the meshing connection between the small gear plate and the large gear plate, the rotating small gear plate drives the large gear plate to rotate, which in turn causes the rotating rod to rotate. The rotating rod drives the adjusting plate to rotate, which in turn drives the vise and the fixed workpiece to rotate, changing the processing angle of the upper surface of the fixed workpiece. When the upper surface of the fixed workpiece rotates to the appropriate position, the motor is turned off, and the workpiece is processed again with the milling cutter. Through the above operation, the effect of adjusting the processing angle and clamping effect of the workpiece is achieved.

[0008] A further feature of this invention is that the externally fixed connection of the vise is a threaded layer, the thickness of which is three centimeters.

[0009] By adopting the above technical solution, the three-centimeter thread layer increases the friction between the workpiece and the inner wall of the vise and the push plate, preventing the workpiece from shifting during processing after clamping.

[0010] A further feature of this invention is that a dial is fixedly connected to the upper surface of the adjustment disc, and the upper surface of the dial is provided with a scale.

[0011] By adopting the above technical solution, the scale set on the upper surface of the dial provides a reference for the rotation angle of the workpiece.

[0012] A further feature of this invention is that a push rod is fixedly connected to the outside of the adjusting disc, and the number of push rods is two.

[0013] By adopting the above technical solution, after the motor is turned off, the worker holds the two push rods and applies force to make the adjustment plate rotate, thereby finely adjusting the rotation angle of the workpiece.

[0014] A further feature of this invention is that an angle iron is fixedly connected to the outside of the clamp plate, and an assembly hole is provided inside the angle iron.

[0015] By adopting the above technical solution, the angle iron and mounting holes facilitate the quick installation of the clamp plate onto the upper surface of the T-slot.

[0016] A further feature of this invention is that a stud is provided on the outside of the clamp plate, and the stud extends through the assembly hole and the threaded hole respectively.

[0017] By adopting the above technical solution, the studs facilitate the limiting and fixing of the clamp plate.

[0018] A further feature of this invention is that a straightening rod is provided on the outside of the machine tool, and a sliding ball is provided at the bottom of the straightening rod, the sliding ball being slidably connected to a T-slot.

[0019] By adopting the above technical solution, the edge line of the vise is always parallel to the edge line of the vise plate. When installing the vise plate, the edge line of the vise plate is made parallel to the straightening rod by sliding the straightening rod, so that the vise plate and the vise plate are perpendicular to the T-slot, providing the original angle for the subsequent processing of parts. The sliding connection between the ball and the T-slot facilitates the movement of the straightening rod.

[0020] A further feature of this invention is that a handle is fixedly connected to the upper surface of the straightening rod, and the number of handles is two.

[0021] By adopting the above technical solution, the two handles make it easier for workers to pull the straightening rod to straighten the installed clamp plate.

[0022] A further feature of this invention is that a shaft plate is fixedly connected inside the clamp plate, and a shaft hole is opened inside the shaft plate, with the other end of the rotating rod penetrating into the shaft hole.

[0023] By adopting the above technical solution, the rotating rod rotates inside the shaft hole when it is subjected to force, and the rotating rod rotates stably when passing through the shaft hole and shaft plate.

[0024] A further feature of this invention is that a placement box is fixedly connected to the upper surface of the machine tool, and a brush is disposed inside the placement box.

[0025] By adopting the above technical solution, the iron filings generated during workpiece processing can easily fall into the T-slot, and workers can clean them with a brush.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the arrangement of a base, machine tool, T-slot, threaded hole, vise plate, motor, rotating hole, small gear plate, large gear plate, rotating rod, adjusting plate, vise, pushing hole, hydraulic press, and clamping plate, allows the worker to fix the vise plate to the outside of the T-slot with studs, place the workpiece inside the vise, and then start the hydraulic press. The hydraulic press starts working, and the output end of the hydraulic press drives the clamping plate to move. The clamping plate, under force, pushes the workpiece against the inner wall of the vise, thus clamping and fixing the workpiece. Then, the milling cutter begins to process the surface of the workpiece. When it is necessary to process other parts of the upper surface of the fixed workpiece... When machining at an angle, the motor is started and begins to rotate. The motor's output drives the small gear disc to rotate. Through the meshing connection between the small gear disc and the large gear disc, the rotating small gear disc drives the large gear disc to rotate, which in turn causes the rotating rod to rotate. The rotating rod drives the adjusting disc to rotate, which in turn drives the vise and the fixed workpiece to rotate, causing the machining angle of the upper surface of the fixed workpiece to change. When the upper surface of the fixed workpiece rotates to the appropriate position, the motor is turned off, and the workpiece is machined again with the milling cutter. Through the above operations, the machining angle of the workpiece can be adjusted and the clamping effect can be achieved.

[0028] 2. This utility model, through the arrangement of the threaded layer, dial, scale, push rod, angle iron, mounting hole, stud, straightening rod, slider, handle, shaft plate, shaft hole, placement box, and brush, increases the friction between the workpiece and the inner wall of the vise and the push plate by a three-centimeter threaded layer, preventing the workpiece from shifting during processing after clamping. The scale on the upper surface of the dial provides a reference for the rotation angle of the workpiece. After the motor is turned off, the worker grips and applies force to the two push rods, which in turn drive the adjusting plate to rotate, thereby fine-tuning the rotation angle of the workpiece. The angle iron and mounting hole facilitate the quick installation of the vise plate onto the upper surface of the T-slot. The column facilitates the limiting and fixing of the vise plate. The edge line of the vise always remains parallel to the edge line of the vise plate. When installing the vise plate, the edge line of the vise plate is made parallel to the straightening rod by sliding the straightening rod, so that the vise plate and vise are perpendicular to the T-slot, providing the original angle for subsequent parts processing. The ball and the T-slot are slidably connected to facilitate the movement of the straightening rod. The two handles make it easy for workers to pull the straightening rod to straighten the installed vise plate. When the rotating rod is subjected to force, it rotates inside the shaft hole. When passing through the shaft hole and shaft plate, the rotating rod rotates stably. Iron filings generated during workpiece processing can easily fall into the inside of the T-slot, and workers can clean the iron filings with a brush. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] Reference Figures 1-4An adjustable milling machine fixture includes a base 1, a machine tool 2 fixedly connected to the upper surface of the base 1, a T-slot 3 fixedly connected to the upper surface of the machine tool 2, a threaded hole 4 inside the T-slot 3, a clamping plate 5 outside the T-slot 3, a motor 6 fixedly connected inside the clamping plate 5, a rotating hole 7 inside the clamping plate 5, a small gear 8 inside the clamping plate 5, the output end of the motor 6 fixedly connected to the small gear 8, a large gear 9 inside the clamping plate 5, the small gear 8 meshing with the large gear 9, a rotating rod 10 fixedly connected to the outside of the large gear 9, an adjusting plate 11 outside the clamping plate 5, one end of the rotating rod 10 penetrating into the rotating hole 7 and fixedly connected to the adjusting plate 11, and a vise 12 fixedly connected to the upper surface of the adjusting plate 11. The vise 12 has a push hole 13 inside. A hydraulic press 14 is fixedly connected to the outside of the vise 12. A clamping plate 15 is installed inside the vise 12. The output end of the hydraulic press 14 passes through the push hole 13 and is fixedly connected to the clamping plate 15. After the worker fixes the vise plate 5 to the outside of the T-slot 3 with studs 22, he places the workpiece inside the vise 12. Then, the hydraulic press 14 is started. The hydraulic press 14 starts working, and the output end of the hydraulic press 14 drives the clamping plate 15 to move. The clamping plate 15, under force, pushes the workpiece against the inner wall of the vise 12, thereby clamping and fixing the workpiece. Then, the milling cutter begins to process the surface of the workpiece. When it is necessary to process the upper surface of the fixed workpiece at a different angle, the motor 6 is started. The motor 6 starts to rotate, and the output end of the motor 6 drives the clamping plate 15 to move. The rotating small gear 8, through its meshing connection with the large gear 9, causes the large gear 9 to rotate, which in turn causes the rotating rod 10 to rotate. The rotating rod 10 then rotates the adjusting plate 11, which in turn rotates the vise 12 and the fixed workpiece, changing the machining angle of the upper surface of the fixed workpiece. When the upper surface of the fixed workpiece reaches the appropriate position, the motor 6 is turned off, and the workpiece is machined again with a milling cutter. This operation achieves the desired adjustment of the workpiece's machining angle and clamping effect. The vise 12 is externally fixed with a threaded layer 16, which is three centimeters thick. This three-centimeter threaded layer 16 increases the friction between the workpiece and the inner wall and push plate of the vise 12, preventing the clamped workpiece from slipping during machining. When the working time deviates, a dial 17 is fixedly connected to the upper surface of the adjusting plate 11. The upper surface of the dial 17 has a scale 18, which provides a reference for the workpiece's rotation angle. Two push rods 19 are fixedly connected to the outside of the adjusting plate 11. After the motor 6 is turned off, the worker grips and applies force to the two push rods 19, causing the adjusting plate 11 to rotate, thus finely adjusting the workpiece's rotation angle. An angle iron 20 is fixedly connected to the outside of the clamp plate 5. The angle iron 20 has an assembly hole 21 inside, facilitating the quick installation of the clamp plate 5 onto the upper surface of the T-slot 3. Studs 22 are provided on the outside of the clamp plate 5, penetrating into both the assembly hole 21 and the threaded hole 4.The stud 22 facilitates the limiting and fixing of the jaw plate 5. A straightening rod 23 is provided on the outside of the machine tool 2, and a ball 24 is provided at the bottom of the straightening rod 23. The ball 24 is slidably connected to the T-slot 3. The edge line of the vise 12 always remains parallel to the edge line of the jaw plate 5. When installing the jaw plate 5, the edge line of the jaw plate 5 is made parallel to the straightening rod 23 by sliding the straightening rod 23, thereby making the jaw plate 5 and the vise 12 perpendicular to the T-slot 3, providing the original angle for subsequent part processing. The slidable connection between the ball 24 and the T-slot 3 facilitates the movement of the straightening rod 23. A handle 25 is fixedly connected to the upper surface of the straightening rod 23. There are two clamp plates 5. Two handles 25 facilitate workers pulling the straightening rod 23 to straighten the installed clamp plate 5. A shaft plate 26 is fixedly connected inside the clamp plate 5. The shaft plate 26 has a shaft hole 27 inside. The other end of the rotating rod 10 passes through the shaft hole 27. When the rotating rod 10 is subjected to force, it rotates inside the shaft hole 27. The rotating rod 10 rotates stably through the shaft hole 27 and the shaft plate 26. A placement box 28 is fixedly connected to the upper surface of the machine tool 2. A brush 29 is installed inside the placement box 28. Iron filings generated during workpiece processing easily fall into the T-slot 3, and workers use the brush 29 to clean them.

[0037] In this invention, after the worker fixes the clamp plate 5 to the outside of the T-slot 3 with studs 22, the workpiece is placed inside the vise 12. Then, the hydraulic press 14 is started, and its output drives the clamping plate 15 to move. The clamping plate 15, under pressure, pushes the workpiece against the inner wall of the vise 12, thus clamping and fixing the workpiece. Next, the milling cutter begins to machine the surface of the workpiece. When it is necessary to machine a different angle on the upper surface of the fixed workpiece, the motor 6 is started, and its output drives the small gear disc 8 to rotate. The meshing connection between the small gear 8 and the large gear 9 causes the rotating small gear 8 to drive the large gear 9 to rotate, which in turn causes the rotating rod 10 to rotate. The rotating rod 10 drives the adjusting plate 11 to rotate, which in turn drives the vise 12 and the fixed workpiece to rotate, causing the machining angle of the upper surface of the fixed workpiece to change. When the upper surface of the fixed workpiece rotates to the appropriate position, the motor 6 is turned off, and the workpiece is machined again with a milling cutter. Through the above operations, the machining angle of the workpiece can be adjusted and the clamping effect can be achieved. The three-centimeter thread layer 16 increases the contact between the workpiece and the inner wall of the vise 12 and the push plate. The friction prevents the workpiece from shifting during processing after clamping. The scale 18 on the upper surface of the dial 17 provides a reference for the rotation angle of the workpiece. After the motor 6 is turned off, the worker grips and applies force to the two push rods 19, which in turn drive the adjusting plate 11 to rotate, thereby fine-tuning the rotation angle of the workpiece. The angle iron 20 and the mounting hole 21 facilitate the quick installation of the clamp plate 5 onto the upper surface of the T-slot 3. The stud 22 facilitates the limiting and fixing of the clamp plate 5. The edge line of the vise 12 always remains parallel to the edge line of the clamp plate 5. When installing the clamp plate 5, the straightening rod 2 is slidable to fix it. 3. Make the edge line of the clamp plate 5 parallel to the straightening rod 23, so that the clamp plate 5 and the vise 12 are perpendicular to the T-slot 3, providing the original angle for subsequent part processing. The sliding ball 24 is slidably connected to the T-slot 3 to facilitate the movement of the straightening rod 23. The two handles 25 make it easy for the worker to pull the straightening rod 23 to straighten the installed clamp plate 5. When the rotating rod 10 is subjected to force and rotates, it rotates inside the shaft hole 27. When passing through the shaft hole 27 and the shaft plate 26, the rotating rod 10 rotates stably. The iron filings generated during workpiece processing can easily fall into the interior of the T-slot 3. The worker can clean the iron filings with a brush 29.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
