Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing equipment, and in particular to a guide rail processing sawing device. Background Art

[0002] A guide rail is a groove or ridge structure made of metal or other materials, used to bear, fix, and guide a moving device or equipment, thereby reducing friction. The longitudinal grooves or ridges on the surface of the guide rail are designed to guide and fix machine components, special equipment, or instruments, etc. The guide rail is also called a slide rail, linear guide rail, or linear slide rail, and is suitable for occasions that require high-precision linear reciprocating motion. Compared with linear bearings, the guide rail can carry a higher rated load and still achieve precise linear motion under high load conditions. During the processing of the guide rail, it is usually necessary to cut a long original guide rail according to the size requirements of the customer.

[0003] After retrieval, a Chinese patent with the patent publication number CN219310222U, a guide rail processing device, includes a processing table. A box body is provided on the processing table. A cutting mechanism is provided inside the box body. A support table is provided on the table surface of the processing table. The two support tables are symmetrically arranged on both sides of the moving path of the saw blade. The support table is used to place the guide rail workpiece. Two cylinders are also provided on the processing table. The two cylinders correspond to one support table respectively. The piston rod of the cylinder faces the box body and is connected with a pressing plate. The box body is also connected with a protective cover, and the protective cover is used to cover the cutting station during processing.

[0004] Although the above patent can realize the sawing of the guide rail workpiece, it still has the following defects in actual application: 1. Lack of an effective extension support mechanism: The above patent supports the guide rail workpiece through the support tables on the left and right sides. The length of the support table is fixed. If the required cutting length of the guide rail workpiece exceeds the length range of the support table, during the cutting process, the guide rail workpiece may sag due to the action of gravity, which will affect the cutting accuracy and the flatness of the end face, and thus reduce the quality of the final product.

[0005] 2. Lack of an effective residual coolant removal mechanism: During the cutting process, coolant is usually used to cool and lubricate the guide rail workpiece and the saw blade. However, the coolant easily flows into the grooves of the guide rail workpiece to form residues. For guide rail workpieces made of metal materials such as carbon steel or cast iron, the residual coolant will cause surface oxidation and rust after contacting with oxygen in the air, thus affecting the quality and service life of the workpiece. Summary of the Invention

The driving member two is used to drive the pressing block to lift and lower. The pressing block descends to press and fix the rail workpiece.

[0013] Preferably, the driving assembly includes a mounting plate connected to the right front side of the frame.

Detailed Description of the Invention

[0033] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Please refer to Figures 1 - 6 , a guide rail processing sawing device, including a machine frame 1. The machine frame 1 includes a central frame 01 and two end frames 02 respectively connected to the front and rear sides of the central frame 01. A roller conveyor 2 for conveying guide rail workpieces is installed on the top of the central frame 01. An X-axis moving platform 3 is provided on the top of the front end frame 02. A circular saw 4 for cutting guide rail workpieces is installed on the X-axis moving platform 3. The circular saw 4 can be driven to move back and forth by the X-axis moving platform 3 to cut the guide rail workpieces. The X-axis moving platform 3 is a prior art and will not be elaborated here. Knife slots 21 for the circular saw blade of the circular saw 4 to move back and forth are opened on the right front sides of the central frame 01 and the roller conveyor 2. A fixing mechanism for fixing the guide rail workpiece is provided on the rear end frame 02. An extended support mechanism for supporting the guide rail workpiece is provided on the right side of the end frame 02. A wiping mechanism for wiping the residual coolant on the guide rail workpiece is provided on the right side of the top of the central frame 01.

[0035] Please refer to Figures 2 - 3 , the fixing mechanism includes a fixing clamp block 51 connected to the right front side of the top of the roller conveyor 2. The fixing clamp block 51 is located on the left side of the circular saw blade of the circular saw 4. An active clamp block 52 is slidably provided on the upper part of the rear end frame 02. A first driving member 53 for driving the active clamp block 52 to move back and forth is installed on the top of the rear end frame 02. The active clamp block 52 moves forward to cooperate with the fixing clamp block 51 to clamp and fix the guide rail workpiece. An L-shaped plate 54 is connected to the top of the rear end frame 02 and located on the left side of the first driving member 53. A second driving member 55 is installed on the front side of the L-shaped plate 54. A pressing block 56 is connected to the second driving member 55. The second driving member 55 is used to drive the pressing block 56 to move up and down. The pressing block 56 descends to press and fix the guide rail workpiece, so that the guide rail workpiece can be firmly fixed to avoid the displacement of the guide rail workpiece during cutting and affecting the cutting accuracy. In a specific implementation, the first driving member 53 and the second driving member 55 can be driving devices such as electric push rods, cylinders, non-bar cylinders, and hydraulic cylinders that can achieve linear motion.

[0036] Please refer to Figures 5 - 6, the wiping mechanism includes a mounting frame 71 connected to the right side of the top of the central frame 01. Both the left and right sides of the mounting frame 71 are open. Sliding rods 72 are provided on the front, rear, and top sides of the mounting frame 71. The sliding rod 72 on the top of the mounting frame 71 is to the right of the front and rear sliding rods 72. A connecting plate 73 located inside the mounting frame 71 is connected to the sliding rod 72. A sponge block 75 for wiping the residual coolant on the guide rail workpiece is connected to the connecting plate 73. A tension spring 74 is sleeved on the sliding rod 72, and the two ends of the tension spring 74 are respectively connected to the connecting plate 73 and the mounting frame 71. The left side of the connecting plate 73 is bent away from the sponge block 75 to facilitate the guide rail workpiece to be moved between the sponge blocks 75. Drain holes 76 are spaced apart at the bottom of the mounting frame 71.

[0037] Please refer to Figure 1 , Figure 3 and Figure 4 , the extension support mechanism includes a guide frame 61 connected to the right side of the rear end frame 02. The guide frame 61 includes an L-shaped connecting plate and three guide rods. The three guide rods are located inside the L-shaped connecting plate and are connected to the L-shaped connecting plate. The L-shaped connecting plate and the guide rods are both connected to the right side of the rear end frame 02. Three movable support plates 62 are slidably arranged between the three guide rods of the guide frame 61 from left to right. The shape of the movable support plate 62 is L-shaped. The three movable support plates 62 are stacked on each other and their tops are flush. A driving component is provided on the right side of the front end frame 02 for driving the three movable support plates 62 to move left and right and to expand and close. The driving component includes a mounting plate 63 connected to the right side of the front end frame 02. The shape of the mounting plate 63 is L-shaped. Three screw rods 64 are rotatably connected at intervals from front to back between the mounting plate 63 and the right side wall of the front end frame 02. The thread pitches of the three screw rods 64 from front to back decrease in sequence. The screw rods 64 penetrate through the movable support plates 62. Nuts 65 are threadedly connected to the three screw rods 64. The front nut 65 is embedded and connected to the lower part of the right movable support plate 62. The middle nut 65 is embedded and connected to the lower part of the middle movable support plate 62. The rear nut 65 is embedded and connected to the lower part of the left movable support plate 62. A driving motor 66 is installed at the inner top of the front end frame 02. A belt 67 is sleeved between the driving motor 66 and the middle screw rod 64 and between two adjacent screw rods 64 through belt pulleys. A fixed support plate 68 is connected between the top of the L-shaped connecting plate of the guide frame 61 and the top of the mounting plate 63. The fixed support plate 68 is located between the mounting frame 71 and the left movable support plate 62. The top of the fixed support plate 68 is flush with the top of the movable support plate 62. The fixed support plate 68 is used to support the guide rail workpiece to improve the stability of the support for the guide rail workpiece.

[0038] First, adjust the position of the movable support plate 62 according to the length of the guide rail workpiece to be cut. Control the driving motor 66 to rotate, and drive the three screw rods 64 to rotate synchronously through the belt 67, so as to drive the three nuts 65 to drive the three movable support plates 62 to move to the right. Since the thread pitches of the three screw rods 64 from front to back decrease in turn, the moving speeds of the three nuts 65 from front to back decrease in turn, and then the moving speeds of the three movable support plates 62 from left to right decrease in turn. The decreasing moving speeds of the three movable support plates 62 moving to the right cause the movable support plates 62 to unfold, so as to achieve the effect of being able to extend and assist in supporting the guide rail workpiece, so as to avoid the guide rail workpiece sagging due to gravity during subsequent cutting of the guide rail workpiece, and then improve the cutting accuracy and the flatness of the end face of the guide rail workpiece. Similarly, controlling the driving motor 66 to reverse can drive the three movable support plates 62 to move to the left and close to adapt to supporting the guide rail workpiece with a shorter required cutting length.

[0039] Then place the guide rail workpiece on the roller conveyor 2 and make the guide rail workpiece close to the fixed clamp block 51. The roller conveyor 2 can convey the guide rail workpiece to the right. The guide rail workpiece enters the installation frame 71, pushes the connecting plates 73 on the front and back sides to move outwards, and pushes the connecting plate 73 on the right side to move upwards, compressing the tension spring 74. The sponge block 75 is kept in close contact with the guide rail workpiece by the force applied by the tension spring 74. The sponge blocks 75 on the front and back sides will fill the grooves on the front and back sides of the guide rail workpiece, and the sponge block 75 on the right side will fill the groove on the top of the guide rail workpiece. Thus, during the process of the guide rail workpiece feeding to the right, the residual coolant on the guide rail workpiece is wiped off by the sponge block 75, reducing the risk of oxidation and rust on the surface of the guide rail workpiece.

[0040] Then control the driving member 1 53 to drive the movable clamp block 52 to move forward to contact the guide rail workpiece, clamp and fix the guide rail workpiece through the cooperation of the movable clamp block 52 and the fixed clamp block 51, and control the driving member 2 55 to drive the pressing block 56 to move down to press and fix the guide rail workpiece to prevent the displacement of the guide rail workpiece during cutting from affecting the cutting accuracy. Then control the X-axis moving platform 3 to drive the circular saw 4 to reciprocate backward and forward, and control the circular saw 4 to work. The circular saw blade of the circular saw 4 moves backward and rotates to saw the guide rail workpiece. After completing a cutting operation, control the driving member 1 53 to drive the movable clamp block 52 to move backward to release the guide rail workpiece, and control the driving member 2 55 to drive the pressing block 56 to move upward to release the guide rail workpiece.

[0041] After an entire guide rail workpiece is cut and moves to the right to disengage from the sponge block 75, under the reset action of the tension spring 74, the connecting plate 73 moves back to its original position, and the front and rear sponge blocks 75 squeeze each other to squeeze out the liquid inside. The sponge block 75 on the right moves downward and squeezes against the mounting frame 71 to squeeze out the liquid, preventing the liquid from remaining on the sponge block 75 all the time and ensuring that the sponge block 75 can continuously and effectively absorb the liquid. The squeezed liquid is discharged through the liquid discharge hole 76 to prevent the liquid from remaining in the mounting frame 71. After an entire guide rail workpiece is completely removed from the mounting frame 71, the next guide rail workpiece is placed for the next round of cutting work.

[0042] Please refer to Figures 5 - 7 , a cavity is provided in the sponge block 75, and an airbag 81 is connected inside the cavity. A cylinder block 82 is installed on the top of the rear end frame 02 and is located on the right side of the driving member 53. The cylinder block 82 is communicated with the airbag 81 through an air delivery pipe 83. A piston 84 is slidably arranged in the cylinder block 82. An adjusting screw rod 85 is threadedly connected to the rear side wall of the cylinder block 82, and the adjusting screw rod 85 is rotatably connected to the piston 84.

[0043] Manually rotating the adjusting screw rod 85 can cause the adjusting screw rod 85 to move forward. The forward movement of the adjusting screw rod 85 drives the piston 84 to move forward, injecting the gas in the cylinder block 82 into the airbag 81 through the air delivery pipe 83, thereby causing the airbag 81 to inflate and expand. The expansion of the airbag 81 will push the sponge block 75 to expand in the groove of the guide rail workpiece, enabling the sponge block 75 to fully fill and contact all parts in the groove, so as to more effectively remove the residual coolant in the groove of the guide rail workpiece. By using the method of the airbag 81 expanding to push the sponge block 75 to expand, not only can it ensure that the coolant is fully wiped off, but also the sponge block 75 can better adapt to guide rail workpieces of different specifications and sizes.

[0044] Please refer to Figures 8 - 10, a positioning mechanism for positioning the guide rail workpiece is provided on the upper left side of the rear end frame 02. The positioning mechanism includes a mounting frame 91 connected to the upper left side of the rear end frame 02. An elastic telescopic positioning frame 92 is slidably arranged on the mounting frame 91 through a guide rod. A third driving member 93 for driving the elastic telescopic positioning frame 92 to move back and forth is installed on the mounting frame 91. The elastic telescopic positioning frame 92 cooperates with the fixed clamping block 51 forward to position the guide rail workpiece, so as to prevent the guide rail workpiece from skewing when being conveyed to the right by the roller conveyor 2, ensure that the guide rail workpiece is fed straight to the right, improve the cutting accuracy and the flatness of the end face of the guide rail workpiece. The elastic telescopic positioning frame 92 includes a movable plate 921, a sliding rod 922, a positioning plate 923 and a support spring 924. The movable plate 921 is slidably connected to the guide rod of the mounting frame 91. Two sliding rods 922 are symmetrically and slidably connected to the front side of the movable plate 921. A positioning plate 923 for positioning the guide rail workpiece is connected between the front ends of the two sliding rods 922. A support spring 924 is sleeved on the sliding rod 922. The two ends of the support spring 924 are respectively connected to the movable plate 921 and the positioning plate 923. The support spring 924 plays a role of buffering and protecting, preventing the positioning plate 923 from rigidly squeezing the guide rail workpiece and causing deformation and damage to the guide rail workpiece. In a specific implementation, the third driving member 93 can be an electric push rod, a cylinder, a non-bar cylinder, a hydraulic cylinder, a linear motor, a screw motor or other driving devices capable of realizing linear motion. Rollers 10 are rotatably arranged at intervals from left to right on the positioning plate 923 of the elastic telescopic positioning frame 92. By means of the rollers 10, the friction between the positioning plate 923 and the guide rail workpiece can be reduced, so that the guide rail workpiece can be fed more smoothly along the positioning plate 923 to the right, and the wear of the positioning plate 923 and the guide rail workpiece can be reduced.

[0045] Please refer to Figure 10 , a transparent cover 11 for covering the cutting station and the circular saw 4 is connected to the top of the front end frame 02. The L-shaped plate 54 extends into the transparent cover 11. An opening 12 for the circular saw 4 and the guide rail workpiece to enter and exit is opened at the lower rear side of the transparent cover 11. Transparent shielding curtains 13 are connected at intervals at the opening 12. By covering the cutting station and the circular saw 4 with the transparent cover 11, it is possible to prevent sparks from splashing everywhere on the worker during the sawing operation. Through the transparent shielding curtains 13, it is possible to prevent sparks from shooting out through the opening 12, thereby protecting the worker and improving safety.

[0046] The above embodiments only represent the preferred implementation modes of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements and substitutions can still be made, and these all belong to the protection scope of the present invention.
