Description

Technical Field

[0001] This utility model belongs to the field of linear guide rail processing, and specifically relates to a linear guide rail blank cutting device. Background Technology

[0002] Linear guides, as an indispensable key component in modern industrial manufacturing, are widely used in automated machinery, precision instruments, and various high-precision equipment. Their core function is to provide stable and precise linear motion guidance, ensuring the high-performance operation of mechanical equipment. However, in the production process of linear guides, especially in the blanking and cutting stage, existing processes face significant efficiency challenges.

[0003] Traditionally, the cutting of linear guide rail blanks has primarily employed a segmented cutting method, meaning that each operation targets only a single rail blank. This cutting mode is not only cumbersome but also inefficient, especially when facing large-scale, batch production demands. As modern industry increasingly demands higher production efficiency, traditional cutting methods can no longer meet the needs of rapid and efficient production, becoming a key factor restricting the increase in linear guide rail production capacity.

[0004] In addition, segmented cutting also has the problem of high labor costs. Specifically, the cutting process requires frequent manual intervention, including blank positioning, cutting parameter adjustment, and waste disposal, which increases labor and time costs. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a linear guide blank cutting device. By setting multiple cutting mechanisms, it realizes multi-segment synchronous cutting of blanks in one clamping, thereby improving the efficiency of blank cutting.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A linear guide blank blank cutting device includes:

[0008] The cutting frame includes two first crossbeams, with legs connected to both ends of the first crossbeams. The upper ends of the legs are higher than the first crossbeams. The cutting frame is surrounded by a panel, with a top plate at the upper end of the panel. A hydraulic cylinder is installed on the top plate.

[0009] Multiple clamps are provided and installed on the first crossbeam for clamping the blank;

[0010] A cutting mechanism includes a splined shaft with both ends rotatably mounted on a first fixed plate. A motor is mounted on one side of the first fixed plate and connected to the splined shaft via a coupling. Sleeves are connected to both sides of the first fixed plate, and the sleeves cooperate with the upper ends of the support legs. A first connecting plate is connected to the upper ends of the two sleeves on the same side. The splined shaft is provided with several clamps, each clamp including a bushing that is slidably sleeved outside the splined shaft. Clamping flanges are threaded to both ends of the bushing. A cutting disc is installed between the clamping flanges on both sides. A protective cover is provided outside the cutting disc, and the protective cover is movably connected to the end of the bushing.

[0011] The fixed frame is a frame structure formed by several second crossbeams and columns. The upper end of the columns is higher than the second crossbeams and is slidably connected to the guide holes on the top plate. The lower end of the fixed frame is connected to the first connecting plate. The upper part of the fixed frame is provided with a top seat, and the piston rod of the hydraulic cylinder is connected to the top seat.

[0012] Furthermore, the fixture includes two sets of support arms for placing and supporting the blank. The two ends of the support arms are connected to end seats, which are mounted on the first crossbeam. Two T-shaped clamps are symmetrically arranged on the upper part of the support arms. Double-ended studs with opposite directions of rotation are rotatably connected to the end seats at both ends. One end of the double-ended stud is connected to a handle, and the two clamps are threadedly connected to the double-ended studs.

[0013] Furthermore, the lower part of the end seat is provided with a sliding groove, which is slidably connected to the first crossbeam. The lower part of the sliding groove is threaded with an adjusting bolt for adjusting the position of the clamp on the first crossbeam.

[0014] Furthermore, a rubber pad is provided on the inner side of the clamp.

[0015] Furthermore, the fixed frame is equipped with a synchronous adjustment mechanism, which includes a scissor-type telescopic frame. A connecting member is provided at the hinge point in the middle of the scissor-type telescopic frame. The connecting member includes a pin, a connecting seat at the lower part of the pin, and a fastening bolt threaded to the upper part of the pin. The connecting member at the front end is connected to the first connecting plate, and the remaining connecting members are connected to the protective cover. A second connecting plate is pivotally connected to the rear end of the scissor-type telescopic frame. A screw is rotatably connected to one side of the second connecting plate, and a handwheel is connected to the end of the screw. A second fixing plate is provided on one side of the fixed frame, and the screw is threadedly connected to the second fixing plate.

[0016] Furthermore, a limiting end plate is fixedly connected to the support leg away from the screw for positioning the end of the blank. The limiting end plate is located directly below the foremost connecting piece, and the inner side of the sleeve is provided with an avoidance groove to accommodate the limiting end plate.

[0017] Furthermore, the second crossbeam is provided with a scale, and the connector on the cutting mechanism near the limiting end plate is provided with a pointer. The pointer has a Z-shaped structure and includes a crimping part, a connecting part, and an indicating part. The crimping part is crimped onto the scissor telescopic frame by fastening bolts. The outer side of the connecting part abuts against the inner side of the second crossbeam, and the indicating part points to the scale.

[0018] Furthermore, the protective cover is provided with cooling mechanisms on both sides. The cooling mechanisms include water inlet pipes, one end of which is connected to the outlet of the water pump via a hose, and the other end of which extends into the interior of the protective cover. Water distribution pipes are provided on both sides of the water inlet pipes, and the two water distribution pipes are located on both sides of the cutting blade. A water tank is provided at the bottom of the cutting frame, and the water inlet of the water pump is connected to the water tank.

[0019] Furthermore, the water tank is equipped with a filter screen inside.

[0020] The beneficial effects of this utility model are:

[0021] 1) By setting multiple cutting blades on the spline shaft, the present invention can cut the blank at the same time during blanking, thereby realizing the simultaneous blanking of multiple sections in one clamping, reducing the number of blank clamping times and improving blanking efficiency.

[0022] 2) The fixture adopts a centering fixture, which ensures that the blank is always located directly below the cutting blade after each clamping, thus guaranteeing the cutting effect of the blank. In addition, the fixture is slidably connected to the first crossbeam, which facilitates the adjustment of the fixture's position on the first crossbeam, ensuring the stability of the blank clamping and the safety of cutting.

[0023] 3) A synchronous adjustment mechanism is set inside the fixed frame. When the blank cutting length is adjusted, the handwheel is turned, and the handwheel drives the second connecting plate to move back and forth, thereby driving the scissor telescopic frame to extend and retract back and forth, thus realizing the synchronous adjustment of multiple cutting mechanisms and ensuring the efficiency and accuracy of the cutting mechanism adjustment.

[0024] 4) A scale is set on the upper part of the second crossbeam, and a pointer is set on the connector of the cutting mechanism near the limit end plate to facilitate quick judgment of the blank cutting length.

[0025] 5) Cooling mechanisms are installed on both sides of the protective cover. When the blank is cut, the coolant in the water tank is pumped and sprayed to both sides of the cutting blade to cool it, which effectively reduces the temperature of the cutting blade, helps to slow down the thermal fatigue and wear of the cutting blade, and extends the service life of the cutting blade.

[0038] The following will be combined with the appendix Figures 1-11The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not 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 utility model.

[0040] like Figure 1 As shown, a linear guide blank cutting device includes a cutting frame 1, a clamp 3, and a cutting mechanism 4, as described above. Figure 2 As shown, the cutting frame 1 includes two first crossbeams 11, with support legs 12 connected to both ends of the first crossbeams 11. The upper end of the support legs 12 is higher than the first crossbeams 11. The cutting frame 1 is surrounded by a surrounding plate 13, and a top plate 14 is provided at the upper end of the surrounding plate 13. A hydraulic cylinder 15 is installed on the top plate 14.

[0041] like Figure 3 As shown, multiple clamps 3 are provided and installed on the first crossbeam 11 for clamping the blank;

[0042] like Figure 6 As shown, the cutting mechanism 4 includes a splined shaft 43, with both ends of the splined shaft 43 rotatably mounted on a first fixed plate 42. A motor 44 is mounted on one side of the first fixed plate 42, and the motor 44 is connected to the splined shaft 43 via a coupling. Sleeves 41 are connected to both sides of the first fixed plate 42, and the sleeves 41 cooperate with the upper ends of the support legs 12. The upper ends of the two sleeves 41 on the same side are connected to a first connecting plate 49. The splined shaft 43 is provided with several clamps 47, such as... Figure 9 , Figure 10 As shown, the clamp 47 includes a bushing 471 that is slidably sleeved on the outside of the spline shaft 43. The two ends of the bushing 471 are threadedly connected to clamping flanges 472. The cutting blade 46 is installed between the clamping flanges 472 on both sides. The cutting blade 46 is provided with a protective cover 45. The protective cover 45 is movably connected to the end of the bushing 471.

[0043] like Figure 6As shown, it also includes a fixing frame 5, which is a frame structure formed by several second crossbeams 52 and columns 51. The upper end of the column 51 is higher than the second crossbeams 52 and is slidably connected to the guide hole 17 on the top plate 14. The lower end of the fixing frame 5 is connected to the first connecting plate 49. The upper part of the fixing frame 5 is provided with a top seat 54, and the piston rod of the hydraulic cylinder 15 is connected to the top seat 54.

[0044] When cutting the blank, the blank is placed on the fixture 3 and clamped. The motor 44 is started. The motor 44 drives multiple cutting blades 46 to rotate simultaneously through the spline shaft 43. Then the piston rod of the hydraulic cylinder 15 extends, driving the fixed frame 5 and the cutting mechanism 4 to move downward to cut the blank. This realizes the simultaneous cutting of multiple sections of the blank in one clamping, reduces the number of blank clamping times, and improves the efficiency of blank cutting.

[0045] As the cutting mechanism 4 moves downward, the sleeve 41 gradually covers the outside of the support leg 12 as the cutting depth increases. The support leg 12 and the column 51 guide the cutting mechanism 4, ensuring the straightness of the cutting surface of the workpiece. In addition, when the lower end of the sleeve 41 contacts the first crossbeam 11, the cutting mechanism 4 cannot continue to move downward, which limits the cutting mechanism 4 and prevents the cutting mechanism 4 from damaging the first crossbeam 11.

[0046] like Figure 4 As shown, the clamp 3 includes two sets of support arms 31 for placing and supporting the blank. The two ends of the support arms 31 are connected to end seats 36, which are mounted on the first crossbeam 11. Two T-shaped clamping plates 32 are symmetrically arranged on the upper part of the support arms 31. Double-ended studs 34 with opposite directions of rotation are rotatably connected to the end seats 36 at both ends. One end of the double-ended studs 34 is connected to a handle 35. The two clamping plates 32 are threadedly connected to the double-ended studs 34. When the blank is clamped, the handle 35 is rotated, and the double-ended studs 34 drive the clamping plates 32 on both sides to move closer to each other, clamping the blank and achieving the centering and clamping of the blank, thus ensuring the cutting effect of the blank.

[0047] like Figure 4 As shown, the lower part of the end seat 36 is provided with a sliding groove 37, which is slidably connected to the first crossbeam 11. The lower part of the sliding groove 37 is threaded with an adjusting bolt 38, which is used to adjust the position of the clamp 3 on the first crossbeam 11, ensuring the stability of the blank clamping and the safety of cutting.

[0048] like Figure 4 As shown, the inner side of the clamping plate 32 is provided with a rubber pad 33 to prevent the clamping plate 32 from scratching the blank when clamping the blank.

[0049] like Figure 6 , Figure 7As shown, the fixed frame 5 is equipped with a synchronous adjustment mechanism 6, which includes a scissor-type telescopic frame 61. A connecting piece 62 is provided at the hinge point in the middle of the scissor-type telescopic frame 61. Figure 8 As shown, the connecting member 62 includes a pin 621, a connecting seat 624 at the lower part of the pin 621, and a fastening bolt 622 threadedly connected to the upper part of the pin 621. The front connecting member 62 is connected to the first connecting plate 49, and the remaining connecting members 62 are connected to the protective cover 45. The rear end of the scissor telescopic frame 61 is pivotally connected to a second connecting plate 63. A screw 64 is rotatably connected to one side of the second connecting plate 63, and a handwheel 65 is connected to the end of the screw 64. A second fixing plate 55 is provided on one side of the fixing frame 5, and the screw 64 is threadedly connected to the second fixing plate 55. When the blank cutting length is adjusted, the handwheel 65 is rotated, and the handwheel 65 drives the second connecting plate 63 to move back and forth, thereby driving the scissor telescopic frame 61 to extend and retract back and forth, thus realizing the synchronous adjustment of multiple cutting mechanisms 4 and ensuring the efficiency and accuracy of the adjustment of the cutting mechanism 4.

[0050] like Figure 2 As shown, a limiting end plate 16 is fixedly connected to the support leg 12 on the side away from the screw 64 for positioning the end of the blank. The limiting end plate 16 is located directly below the foremost connecting member 62, that is, the distance between the limiting end plate 16 and the cutting blade 46 closest to the limiting end plate 16 is equal to the distance between adjacent cutting blades 46, which facilitates the rapid and accurate positioning of the blank. The sleeve 41 is provided with an avoidance groove 411 to accommodate the limiting end plate 16, ensuring the stroke of the cutting mechanism 4.

[0051] like Figure 6 As shown, the second crossbeam 52 is provided with a scale 53, and the connector 62 on the cutting mechanism 4 near the limiting end plate 16 is provided with a pointer 623, such as... Figure 8 As shown, the pointer 623 has a Z-shaped structure and includes a pressing part, a connecting part, and an indicating part. The pressing part is pressed onto the scissor-type telescopic frame 61 by fastening bolts 622. The outer side of the connecting part abuts against the inner side of the second crossbeam 52, preventing the pointer 623 from rotating when the synchronous adjustment mechanism 6 is adjusted. The indicating part points to the scale 53. By setting the pointer 623 and the scale 53, it is convenient to quickly determine the length of the blank. In addition, with the cooperation of the synchronous adjustment mechanism 6, only one pointer 623 is needed to determine the length of multiple sections of the same blank.

[0052] like Figure 9 As shown, cooling mechanisms 48 are provided on both sides of the protective cover 45. Each cooling mechanism 48 includes a water inlet pipe 481. One end of the water inlet pipe 481 is connected to the outlet of a water pump via a flexible hose (not shown in the figure), and the other end of the water inlet pipe 481 extends into the interior of the protective cover 45. Figure 11As shown, the inlet pipe 481 is provided with two branch pipes 482 on both sides, and the two branch pipes 482 are located on both sides of the cutting blade 46; as Figure 1 As shown, the bottom of the cutting frame 1 is equipped with a water tank 2, and the water inlet of the water pump is connected to the water tank 2. When the blank is cut, the coolant in the water tank 2 is pumped and sprayed to both sides of the cutting blade 46 to cool the cutting blade 46, which effectively reduces the temperature of the cutting blade 46, helps to slow down the thermal fatigue and wear of the cutting blade 46, and extends the service life of the cutting blade 46. The sprayed coolant falls back into the water tank 2, realizing the recycling of the coolant.

[0053] like Figure 5 As shown, the water tank 2 is equipped with a filter screen 21 to filter the chips in the coolant and reduce the wear of the water pump.

[0054] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
