Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of machining technology, and more specifically, to a metal band saw for machining piston rods. Background Technology

[0002] As a connecting component used in hydraulic cylinders and pneumatic cylinders to perform piston work, the quality of its machining directly affects the lifespan and reliability of the entire product. High machining precision is required, necessitating a piston rod machining fixture to securely fix it before machining to obtain the desired piston rod. Band saws primarily use saw bands or saw blades as cutting tools to cut various metal materials such as alloy structural steel, medium carbon steel, low alloy steel, high alloy steel, special alloy steel, stainless steel, bearing steel, acid-resistant steel, and straightening steel. Band saws are characterized by high cutting speed, high dimensional accuracy, and low material loss, and are widely used in material preparation workshops to cut various bars, pipes, and other profiles.

[0003] Existing clamping structures can only achieve fixation in a single direction. When processing multiple piston rods simultaneously, the lateral impact force of the saw blade during sawing can easily cause the workpiece to slide laterally, while the workpiece's own weight and cutting vibration can cause vertical movement. The superposition of these two types of displacement can result in tilting of the cutting surfaces of each piston rod and excessive length deviation. In addition, some structures lack precise guide and limiting components, making the clamping mechanism prone to offset during movement, further exacerbating the clamping misalignment problem and seriously affecting the dimensional consistency of batch processing. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a metal band saw for piston rod processing, which solves the technical problems in the prior art where clamping is fixed in one direction and easily shifts, and the lack of guides aggravates misalignment, affecting the consistency of batch processing dimensions.

[0005] According to one aspect, at least one embodiment of this disclosure provides a metal band saw for machining piston rods, comprising: The band saw body has two connecting plates and two connecting blocks symmetrically fixedly installed on it. A base, on which a mounting bracket is fixedly installed; A screw rod is provided, and a first motor is fixedly mounted on the mounting bracket. The output shaft of the first motor passes through the mounting bracket and is fixedly connected to the screw rod. Pressure plate; a fixed cylinder is threadedly connected to the screw, and a first anti-slip pad is fixedly connected to the bottom end of the fixed cylinder.

[0006] For example, at least one embodiment of this disclosure provides a metal band saw for processing piston rods, wherein two limiting rods are fixedly installed between the mounting frame and the base, and the pressure plate is slidably connected to the two limiting rods.

[0007] For example, at least one embodiment of this disclosure provides a metal band saw for processing piston rods, wherein a fixed seat is fixedly installed on the base, and the fixed seat is in the shape of an "L".

[0008] For example, at least one embodiment of this disclosure provides a metal band saw for processing piston rods, wherein the fixed base has a saw blade groove.

[0009] For example, at least one embodiment of this disclosure provides a metal band saw for processing piston rods, wherein a movable groove is provided on the fixed base, a lead screw is rotatably connected to the inside of the movable groove via a bearing, a movable block is threaded onto the lead screw, a second motor is fixedly installed on the fixed base, and the output shaft of the second motor extends into the inside of the movable groove and is fixedly connected to one end of the lead screw.

[0010] For example, at least one embodiment of this disclosure provides a metal band saw for processing piston rods, wherein a clamping seat is fixedly installed on the top of the movable block extending to the top of the movable groove, and a second anti-slip pad is provided on one side of the clamping seat.

[0011] For example, at least one embodiment of this disclosure provides a metal band saw for processing piston rods, wherein two slide rods are fixedly installed inside the movable groove, and the movable block is slidably connected to the two slide rods.

[0012] For example, at least one embodiment of this disclosure provides a metal band saw for processing piston rods, wherein two guide rods are fixedly installed on the base, and the top ends of the two guide rods are fixedly installed to the same top plate.

[0013] For example, at least one embodiment of this disclosure provides a metal band saw for processing piston rods, wherein both of the connecting blocks are slidably connected to the guide rod.

[0014] For example, at least one embodiment of this disclosure provides a metal band saw for processing piston rods, wherein two electric push rods are fixedly installed at the bottom end of the top plate, and the output ends of the two electric push rods are respectively fixedly connected to a connecting plate.

[0015] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the second motor is started, and the output shaft of the second motor drives the lead screw to rotate. With the cooperation of the two slide rods, the movable block moves along the surface of the lead screw until the clamping seat drives the second anti-slip pad to fit tightly against the piston rod. The second anti-slip pad can increase the friction between the clamping seat and the piston rod, prevent the piston rod from moving laterally during cutting, and avoid the clamping seat and the piston rod from hard contact causing scratches on the rod surface, thus achieving precise clamping of piston rods of different diameters. The first motor is started, and its output shaft drives the screw to rotate. With the cooperation of the two limit rods, the fixed cylinder moves along the surface of the screw. The fixed cylinder drives the pressure plate to move until the pressure plate drives the first anti-slip pad to press the top of the piston rod, preventing multiple piston rods from moving vertically during sawing. Together with the clamping seat, a two-way anti-displacement clamping system is formed to prevent the piston rod from moving up and down or shifting during cutting, which would affect the cutting accuracy and further enhance the clamping stability of the piston rod.

[0018] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0019] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0020] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0021] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figures 1-5 As shown, it illustrates a metal band saw for processing piston rods according to an embodiment of the present disclosure, comprising: a band saw body 4, on which two connecting plates 3 and two connecting blocks 5 are symmetrically fixedly mounted; Base 1, on which mounting bracket 11 is fixedly installed; Screw 13; A first motor 12 is fixedly mounted on the mounting bracket 11, and the output shaft of the first motor 12 passes through the mounting bracket 11 and is fixedly connected to the screw 13; Pressure plate 15; a fixed cylinder 14 is threadedly connected to the screw 13, and a first anti-slip pad 16 is fixedly connected to the bottom end of the fixed cylinder 14.

[0025] The first motor 12 drives the screw 13 to move the fixed cylinder 14 and the pressure plate 15. With the cooperation of the first anti-slip pad 16, a vertical clamping force can be formed on the piston rod 20. The first anti-slip pad 16 can increase the friction with the piston rod 20 to prevent vertical sliding, and also avoid hard contact to avoid damaging the surface of the rod, thus providing a stable vertical fixing foundation for subsequent sawing.

[0026] Two limiting rods 10 are fixedly installed between the mounting bracket 11 and the base 1, and the pressure plate 15 is slidably connected to the two limiting rods 10.

[0027] The limiting rod 10 can restrict the movement direction of the pressure plate 15, ensuring that the pressure plate 15 moves smoothly only in the vertical direction, avoiding the pressure plate 15 from deviating in the clamping position due to the transmission offset of the screw 13, thereby ensuring that the multiple piston rods 20 are subjected to uniform force and improving the accuracy of vertical clamping.

[0028] A fixing seat 9 is fixedly installed on the base 1, and the fixing seat 9 is "L" shaped.

[0029] like Figures 4-5 As shown, the "L"-shaped fixing seat 9 can provide support surfaces for the piston rod 20 in both horizontal and vertical directions. Multiple piston rods 20 can be placed side by side and axially positioned to prevent the piston rods 20 from being placed crookedly. This lays a regular placement foundation for subsequent clamping and sawing, and is suitable for batch processing needs.

[0030] like Figures 3-5 As shown, the fixed base 9 is provided with a saw blade groove 8. The saw blade groove 8 can provide clearance for the saw blade during the sawing process, preventing the saw blade from colliding with the fixed base 9 and causing damage to the saw blade or deformation of the fixed base 9. At the same time, it ensures that the saw blade can completely cut the piston rod 20, avoiding incomplete cutting or uneven cutting surface due to space limitations.

[0031] like Figures 4-5As shown, the fixed base 9 also has a movable groove 21. A lead screw 22 is rotatably connected to the inside of the movable groove 21 via a bearing. A movable block 23 is threaded onto the lead screw 22. A second motor 17 is fixedly installed on the fixed base 9. The output shaft of the second motor 17 extends into the movable groove 21 and is fixedly connected to one end of the lead screw 22. By driving the lead screw 22 with the second motor 17, the movable block 23 can be moved, allowing for flexible adjustment of the position of subsequent clamping components. This adapts to the lateral clamping requirements of different diameters and numbers of piston rods 20, enabling the processing of multi-specification workpieces without changing the fixture, thus improving the equipment's versatility.

[0032] like Figures 4-5 As shown, a clamping seat 18 is fixedly installed on the top of the movable block 23 extending to the top of the movable groove 21, and a second anti-slip pad 19 is provided on one side of the clamping seat 18.

[0033] like Figures 4-5 As shown, the clamp 18, in conjunction with the second anti-slip pad 19, can form a lateral clamping force on the piston rod 20. The second anti-slip pad 19 can increase the friction with the piston rod 20 to prevent lateral sliding. At the same time, the flexible material can prevent the clamp 18 from scratching the surface of the piston rod 20. It works with the vertical pressure plate 15 to form a bidirectional clamping, further improving the clamping stability of the piston rod 20.

[0034] like Figure 5 As shown, two slide rods 24 are fixedly installed inside the movable groove 21, and the movable block 23 is slidably connected to the two slide rods 24. The slide rods 24 can limit the movement direction of the movable block 23, prevent the movable block 23 from rotating with the lead screw 22 and causing the clamping seat 18 to shift, ensure that the clamping seat 18 always moves smoothly laterally along the piston rod 20, ensure accurate lateral clamping position, and prevent uneven force on the piston rod 20 due to the tilt of the clamping seat 18.

[0035] like Figure 2 As shown, two guide rods 2 are fixedly installed on the base 1, and the top ends of the two guide rods 2 are fixedly installed to the same top plate 7. The guide rods 2 and the top plate 7 form a stable lifting guide frame, which provides support and directional restriction for the up and down movement of the band saw body 4, avoids shaking or deviation of the band saw body 4 during the sawing process, and ensures the stability of the saw blade cutting path.

[0036] like Figure 2 As shown, both connecting blocks 5 are slidably connected to the guide rod 2. The sliding engagement between the connecting blocks 5 and the guide rod 2 ensures that the band saw body 4 moves smoothly up and down along the direction of the guide rod 2, further limiting the offset of the band saw body 4, enabling the saw blade to be accurately aligned with the cutting position, and improving cutting accuracy.

[0037] like Figure 2As shown, two electric push rods 6 are fixedly installed at the bottom of the top plate 7, and the output ends of the two electric push rods 6 are respectively fixedly connected to the connecting plate 3.

[0038] like Figure 2 As shown, the two electric push rods 6 symmetrically drive the connecting plate 3 to raise and lower the band saw body 4, which can provide stable and uniform lifting power and avoid the band saw body 4 from tilting due to force on one side. At the same time, the electric push rods 6 are highly controllable and can accurately adjust the sawing feed speed and depth to adapt to the sawing needs of piston rods 20 of different materials.

[0039] In use, multiple piston rods 20 to be processed are placed side by side on the fixed seat 9. The second motor 17 is started, and the output shaft of the second motor 17 drives the lead screw 22 to rotate. With the cooperation of the two slide rods 24, the movable block 23 moves along the surface of the lead screw 22 until the clamping seat 18 drives the second anti-slip pad 19 to fit tightly against the piston rod 20. The second anti-slip pad 19 can increase the friction between the clamping seat 18 and the piston rod 20, preventing the piston rod 20 from moving laterally during cutting, and can also avoid the clamping seat 18 and the piston rod 20 from hard contact causing scratches on the rod surface, thus achieving precise clamping of piston rods 20 of different diameters. Next, based on the cutting position of the piston rod 20, the first motor 12 is started. The output shaft of the first motor 12 drives the screw 13 to rotate. With the cooperation of the two limit rods 10, the fixed cylinder 14 moves along the surface of the lead screw 22. The fixed cylinder 14 drives the pressure plate 15 to move until the pressure plate 15 drives the first anti-slip pad 16 to press the top of the piston rod 20, so as to prevent multiple piston rods 20 from moving vertically during sawing. Together with the clamping seat 18, a two-way anti-displacement clamping system is formed to prevent the piston rod 20 from moving up and down or shifting during cutting, which would affect the cutting accuracy and further enhance the clamping stability of the piston rod 20. After clamping is completed, the two electric push rods 6 are started simultaneously using the external control system. The output end of the electric push rod 6 pushes the connecting plate 3 to move downward. Since the connecting block 5 of the band saw body 4 is slidably connected to the guide rod 2 on the base 1, the guide rod 2 can provide stable guidance for the lifting and lowering of the band saw body 4, preventing the band saw body 4 from deviating during the descent. The band saw body 4 drives the saw blade to move downward synchronously. When the saw blade contacts the piston rod 20, the cutting operation begins. The saw blade groove 8 on the fixed seat 9 can provide cutting space for the saw blade, preventing the saw blade from colliding with the fixed seat 9 and causing damage, while ensuring that the cutting surface is flat. After the cutting is completed, the electric push rod 6 drives the band saw body 4 to rise back, and then the second motor 17 and the first motor 12 on the mounting frame 11 are started in reverse, so that the clamp 18 and the pressure plate 15 are disengaged from the piston rod 20, and the processed piston rod 20 can be taken out.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
