Description

Technical Field

[0001] The present invention relates to the technical field of cutting machine tools, and particularly to a metal cutting machine tool with a guide block structure. Background Art

[0002] A metal cutting machine tool is a machine that processes metal workpieces by methods such as cutting and special machining to obtain the required geometric shape, dimensional accuracy, and surface quality. It is a machine for manufacturing machines, also known as a mother machine or tool machine. It mainly uses the relative movement between the tool and the workpiece to remove excess metal material from the workpiece to meet the specified shape, size, and surface quality requirements.

[0003] Among them, the guiding structure is the main component for controlling the movement path and accuracy of the machine tool, mainly including the slide rail and slide seat that support and carry the workbench, and the ball screw that drives the horizontal movement of the workbench. The guide rail is an important component in the metal cutting machine tool that provides guidance and support for the moving parts. It guides the moving parts of the tool or workpiece to move accurately along a certain trajectory, ensures the machining accuracy, and bears loads such as cutting force and gravity.

[0004] During the cutting work, a large amount of metal chips will be generated. To protect the slide rail and slide seat, a sealing strip is usually provided at the end face of the slide seat. The sealing strip is used to push the metal chips that fall on the slide rail. However, after the sealing strip is used for a period of time, it is easy to wear and damage, resulting in some metal chips invading between the slide seat and the slide rail, causing wear of the slide seat and the slide rail. Therefore, it is necessary to regularly clean the inside of the slide seat to avoid the accumulation of metal chips. However, the corresponding cleaning work of the machine tool for the slide seat and the slide rail is relatively cumbersome. It is necessary to disassemble the workbench together with the slide seat and then lift it by hoisting to carry out the cleaning. Such a method not only has a high working intensity but also has a low efficiency. Summary of the Invention

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides a metal cutting machine tool with a guide block structure, having the following beneficial effects:

[0022] 1. By providing a jacking member and a supporting member, when it is necessary to clean and maintain the inside of the slide seat, the hydraulic cylinder in the jacking member is started, and the top cross frame fits with the bottom surface of the side wing plate, and the workbench is jacked upward by using the side wing plate, so that the workbench drives the slide seat to be separated from the slide rail. At this time, the metal chips and waste lubricating oil in the slide seat can be scraped off, and then new lubricating oil is applied, achieving the purpose of separating the slide seat from the slide rail by a lifting device that is not conducive to hoisting, and facilitating the maintenance work of the slide seat;

[0023] In addition, a supporting member is further provided. After the jacking member jacks up the workbench, the opening and closing mechanism in the supporting member will drive the rotating frame to rotate, and the rotating rotating frame will drive the connected support frame to rotate, so that the support frame rotates between the workbench and the machine base. Then the jacking member unloads the force, and the support frame uses its rigid structure to support the workbench, achieving the purpose of stably fixing the workbench after it is jacked up. On the one hand, it avoids the damage of the hydraulic cylinder and the accidental fall of the workbench, and on the other hand, it can shorten the continuous working time of the hydraulic cylinder and improve the service life of the hydraulic cylinder.

[0024] 2. By setting a limit plate and a linkage component, in the normal state, the limit plate is pushed by the second spring and is in a state of being in contact with the bottom surface of the slide rail cornice. At this time, the slide seat is in an engaged state with the slide rail by using the limit plate. The slide seat can still slide linearly along the slide rail, but cannot move upward or laterally. In this way, the safety of the slide seat and the workbench during movement can be ensured, and the overturning problem can be prevented. When it is necessary to separate the slide rail from the slide seat, the hydraulic cylinder also drives the cross frame to move upward. At this time, the ejector rod on the cross frame will first contact the linkage component and jack up the linkage component. When the linkage component moves, it will use the internal pull rope to pull the limit plate, so that the limit plate is disengaged from the bottom surface of the slide rail cornice. At this time, the slide seat can move upward smoothly.

[0025] 3. By setting a clamping seat and a positioning component, in the normal state, the clamping seat is inserted into it through the side clamping groove on the side of the bushing. When the lead screw drives the bushing to move, the bushing will drive the clamping seat to move by using the side clamping groove, so that the clamping seat drives the workbench to move horizontally. When the workbench is jacked up, the clamping seat will directly move upward under the drive of the workbench, so that the clamping seat is separated from the side clamping groove. In this way, it can avoid the cumbersome work of manually removing the connection between the workbench and the bushing when jacking up the workbench, and improve the work efficiency;

[0026] The positioning component serves the purpose of fixing the bushing. When the workbench is not jacked up, it will squeeze the positioning component, so that the positioning plate in the positioning component is separated from the lower clamping groove. At this time, the bushing can move freely. But when the workbench moves upward, the positioning component will lose the extrusion and stretch upward. Correspondingly, the internal positioning plate will move upward to fit with the lower clamping groove of the bushing. At this time, the bushing cannot move or flip. In this way, it is ensured that when the workbench and the clamping seat are reset, they can be stably aligned and clamped with the bushing. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] Embodiment, please refer toFigures 1-10 , a metal cutting machine tool with a guiding block structure, comprising a machine base 1, on which a driving box 2, a slide rail 4, a driving motor 7 and a workbench 5 are provided. A chuck 3 is provided on the driving box 2, a slide block 11 connected to the bottom surface of the workbench 5 is provided on the slide rail 4, a lead screw 6 is provided at the output end of the driving motor 7, and a bushing 13 connected to the bottom of the workbench 5 is provided on the lead screw 6. Flanking plates 12 are provided on both sides of the workbench 5, and a lifting member 8 is provided on the machine base 1 at a position corresponding to the flanking plates 12, and a supporting member 9 is provided inside the lifting member 8;

[0048] The lifting member 8 includes two hydraulic cylinders 801, and a cross frame 802 is provided at the top ends of the two hydraulic cylinders 801, and the cross frame 802 is in contact with the bottom surface of the flanking plate 12;

[0049] Two sets of lifting members 8 are provided, respectively located on both sides of the machine base 1, and each of them contains two hydraulic cylinders 801 inside. By using the upward lifting of the hydraulic cylinders 801, the cross frame 802 is pushed, so that the cross frame 802 is in contact with the flanking plate 12, and the workbench 5 is lifted upward by using the flanking plate 12, so that the slide block 11 at the lower part of the workbench 5 is separated from the slide rail 4, which is convenient for cleaning the bottom inside the slide block 11. Compared with the method of using a hoisting device to lift the workbench 5, the process using the hydraulic cylinders 801 is smoother, safer, faster, and the lifting process can be automatically completed. In addition, it should be further noted that before lifting the workbench 5, the connection between the bushing 13 and the workbench 5 needs to be disassembled first.

[0050] The supporting member 9 includes two rotating frames 901, the two rotating frames 901 are provided at both ends of the cross frame 802, an opening and closing mechanism 903 is provided at the top ends of the rotating frames 901, the opening and closing mechanism 903 is located inside the cross frame 802 and is connected with a reduction motor 904, a supporting frame 902 is provided on the side surface of the rotating frame 901, the top end of the supporting frame 902 is in contact with the bottom surface of the workbench 5, and the bottom end of the supporting frame 902 is in contact with the top surface of the machine base 1;

[0051] In the present invention, the rotating frame 901 and the supporting frame 902 are provided. The rotating frame 901 can rotate under the drive of the opening and closing mechanism 903, and the supporting frame 902 is brought into or away from the machine base 1 by rotation. When the workbench 5 is lifted, the rotating frame 901 rotates the supporting frame 902 onto the machine base 1, so that the supporting frame 902 is located between the workbench 5 and the machine base 1. In this way, it can be avoided that the hydraulic cylinder 801 accidentally loses force, resulting in the problem of the workbench 5 falling. On the other hand, it can also be avoided that the hydraulic cylinder 801 is in a stressed state for a long time, reducing the working time of the hydraulic cylinder 801 and improving its service life.

[0052] The opening and closing mechanism 903 includes a driving gear 9031 connected to the reduction motor 904, and driving racks 9032 are meshed on both sides of the driving gear 9031. The driving rack 9032 is connected to a driven rack 9035 through a connecting rod 9033. A sliding sleeve 9034 connected to the horizontal frame 802 is provided on the side of the connecting rod 9033. A driven gear 9036 connected to the rotating frame 901 is meshed on the side of the driven rack 9035.

[0053] By providing an active rack 9032 and a driven rack 9035, the active rack 9032 can move linearly by utilizing the rotation of the active gear 9031, and transmit power to the driven rack 9035 by utilizing the connecting rod 9033, so that the driven rack 9035 drives the driven gear 9036 meshing therewith to rotate, so that the driven gear 9036 drives the rotating frame 901 to rotate, and the active rack 9032 is arranged on both sides of the active gear 9031, so that the rotating frames 901 linked on both sides rotate in opposite directions, that is, to ensure that the rotating frames 901 are synchronously unfolded and stored.

[0054] The side wing plate 12 is provided with a plug-in hole 17, and the horizontal frame 802 is provided with a plug-in rod 803 which limits the horizontal sliding of the side wing plate 12 through the plug-in hole 17;

[0055] By setting the plug-in hole 17 and the plug-in rod 803, when the cross frame 802 contacts the side wing plate 12, the plug-in rod 803 on the cross frame 802 will be inserted into the plug-in hole 17 on the side wing plate 12, so that the position of the side wing plate 12 is restricted, and the side wing plate 12 is used to stabilize the workbench 5 to prevent the workbench 5 from sliding horizontally and offsetting after being lifted, thereby ensuring that the position of the workbench 5 is always in a stable state.

[0056] The top and bottom surfaces of the support frame 902 are both provided with a fitting plate 905, an upper slide groove 18 that fits with the fitting plate 905 is provided under the workbench 5, and a lower slide groove 22 that fits with the fitting plate 905 is provided on the machine base 1;

[0057] By setting the interlocking plate 905, the lower slide groove 22 and the upper slide groove 18, the lower slide groove 22 is opened on the machine base 1, and the upper slide groove 18 is opened under the workbench 5, and the positions of the two are the same as the movement path of the interlocking plate. When the support frame 902 is rotated to the supporting position by the rotating frame 901, the interlocking plates 905 located at both ends of the support frame 902 will be inserted into the lower slide groove 22 and the upper slide groove 18, so that the machine base 1 is connected to the workbench 5 as a whole through the support frame 902, preventing the workbench 5 from being offset and overturned after being jacked up, and further ensuring the safety of the cleaning process of the slide 11.

[0058] refer to Figure 7, specifically, a protruding cornice is provided on the outer side of the sliding rail 4, a limiting plate 16 that fits against the bottom surface of the cornice is slidably provided on the outer side of the sliding seat 11, a second spring 19 is provided between the limiting plate 16 and the sliding seat 11, the outer end of the limiting plate 16 is connected to a linkage member 10, the linkage member 10 is provided under the workbench 5, and a push rod 804 for triggering the linkage member 10 is provided on the cross frame 802;

[0059] By providing the limiting plate 16 and the linkage member 10, the limiting plate 16 connects the sliding seat 11 to the sliding rail 4 by fitting against the bottom surface of the cornice of the sliding rail 4, so that the sliding seat 11 can only move linearly along the sliding rail 4, preventing the sliding seat 11 from tilting and shifting, or the problem of the workbench 5 tipping over. The second spring 19 connected to the limiting plate 16 applies a pulling force to the limiting plate 16, so that the limiting plate 16 is in a state of fitting against the sliding rail 4 without external force, ensuring the stability of the position of the limiting plate 16, and enabling the limiting plate 16 to automatically reset after losing the external acting force;

[0060] The linkage member 10 connected to the limiting plate 16 can utilize the fact that the push rod 804 contacts the cross frame 802 first, drive the linkage member 10 by the upward movement of the cross frame 802, and pull the limiting plate 16 by the linkage member 10, so that the limiting plate 16 can be automatically separated from the sliding rail 4 before the workbench 5 is lifted.

[0061] The linkage member 10 includes a support sleeve 1001 provided on the side of the workbench 5, a sliding rod 1002 is slidably provided in the support sleeve 1001, a pulling rope 1004 is provided on the bottom surface of the sliding rod 1002, the other end of the pulling rope 1004 is connected to the limiting plate 16, and a linkage frame 1003 is provided on the top surface of the sliding rod 1002, and the linkage frame 1003 is vertically aligned with the push rod 804;

[0062] By providing the linkage frame 1003 and the pulling rope 1004, the linkage frame 1003 vertically moves in the support sleeve 1001 by the sliding rod 1002. When the cross frame 802 moves upward, the push rod 804 on the cross frame 802 will contact the linkage frame 1003 first and push the linkage frame 1003 upward, so that the linkage frame 1003 drives the pulling rope 1004 to move through the sliding rod 1002, and the limiting plate 16 is removed by the pulling rope 1004, making full use of the original movement of the cross frame 802 to achieve the linkage effect and saving the setting cost of additional driving sources.

[0063] A support pulley 1005 for changing the angle of the pulling rope 1004 is provided under the workbench 5;

[0064] By providing the support pulley 1005, the angle and direction of the pulling rope 1004 can be changed by the support pulley 1005, so that the pulling rope 1004 remains horizontal with the limiting plate 16. The horizontal pulling rope 1004 can more conveniently pull the limiting plate 16, preventing the limiting plate 16 from being unevenly stressed and prone to eccentric wear problems.

[0065] Reference Figure 8 、 9 、 10. Specifically, side slots 20 are provided on both sides of the bushing 13. A clamping seat 14 is provided under the workbench 5 and is inserted onto the bushing 13 through the side slots 20. A lower slot 21 is provided under the bushing 13. A positioning member 15 for locking the position of the bushing 13 through the lower slot 21 is provided on the machine base 1;

[0066] By providing the slots and the clamping seat 14, normally, the clamping seat 14 is inserted into the bushing 13 through the side slots 20 on the side of the bushing 13. When the lead screw 6 drives the bushing 13 to move, the bushing 13 will drive the clamping seat 14 to move by using the side slots 20, so that the clamping seat 14 drives the workbench 5 to move horizontally. When the workbench 5 is lifted upward, the clamping seat 14 will directly move upward under the drive of the workbench 5, so that the clamping seat 14 is separated from the side slots 20. In this way, it is possible to avoid the cumbersome work of manually removing the connection between the workbench 5 and the bushing 13 when lifting the workbench 5, and improve the work efficiency.

[0067] The positioning member 15 includes a support rod 1503 provided on the machine base 1. A support plate 1501 is slidably provided on the support rod 1503. A first spring 1504 connected to the support plate 1501 is sleeved outside the support rod 1503. A positioning plate 1502 that fits with the lower slot 21 is provided on the support plate 1501. A trigger plate 1505 that fits with the bottom surface of the workbench 5 is provided on the support plate 1501;

[0068] By providing the positioning member 15, the positioning member 15 serves to fix the bushing 13. When the workbench 5 is not lifted, it will squeeze the positioning member 15, so that the positioning plate 1502 in the positioning member 15 is separated from the lower slot 21. At this time, the bushing 13 can move freely. However, when the workbench 5 moves upward, the positioning member 15 will stretch upward due to the loss of extrusion. Correspondingly, the positioning plate 1502 inside it will move upward to fit with the lower slot 21 of the bushing 13. At this time, the bushing 13 cannot move or flip. In this way, it is ensured that when the workbench 5 and the clamping seat 14 are reset, they can be stably aligned and clamped with the bushing 13. It should be further noted that the first spring 1504 exerts an upward thrust on the support plate 1501.

[0069] Slant slide frames 1506 that fit with the bottom surface of the workbench 5 are provided on both sides of the trigger plate 1505;

[0070] By setting the inclined sliding frame 1506, the inclined sliding frame 1506 can be attached to the bottom surface and the side of the workbench 5. When the workbench 5 moves out of the position of the trigger plate 1505 during operation, the trigger plate 1505 will lose the extrusion, and then it will move upward under the drive of the support plate 1501 and the first spring 1504. At this time, the trigger plate 1505 will exceed the bottom surface of the workbench 5 and instead be located on the side plate of the workbench 5. When the workbench 5 is reset, the side of the workbench 5 will first contact the inclined sliding frame 1506, and the inclined sliding frame 1506 will press the trigger plate 1505 downward again to prevent interference problems between the trigger plate 1505 and the workbench 5.

[0071] Working principle: When it is necessary to separate the sliding seat 11 from the sliding rail 4, the driving motor 7 drives the workbench 5 to move to the corresponding position through the lead screw 6 and the bushing 13, and then the hydraulic cylinder 801 drives the cross frame 802 to move upward. The ejector rod 804 on the cross frame 802 first contacts the linkage frame 1003 and jacks up the linkage frame 1003, so that the linkage frame 1003 drives the pull rope 1004 to move through the slide rod 1002. The pull rope 1004 moves on the side of the support pulley 1005 and pulls the limit plate 16, so that the limit plate 16 is separated from the sliding rail 4. Then the cross frame 802 fits with the bottom surface of the flank plate 12, and at the same time the insertion rod 803 is aligned with the insertion hole 17. The flank plate 12 is used to jack up the workbench 5. At the same time, the clamping seat 14 at the bottom of the workbench 5 is separated from the bushing 13, and then the trigger plate 1505 loses the extrusion of the workbench 5, so that the first spring 1504 jacks up the support plate 1501, and the positioning plate 1502 on the support plate 1501 is inserted into the lower card slot 21 of the bushing 13 to fix the position of the bushing 13;

[0072] After the workbench 5 is jacked up, the reduction motor 904 drives the driving gear 9031 to rotate. The driving gear 9031 drives the driving racks 9032 engaged on both sides to move. The driving racks 9032 drive the driven rack 9035 at the end through the connecting rod 9033. The driven rack 9035 drives the driven gear 9036 engaged with it to rotate by linear movement. The driven gear 9036 drives the support frame 902 to rotate through the rotating frame 901. The support frame 902 rotates between the workbench 5 and the machine base 1. At the same time, the fitting plates 905 at both ends of the support frame 902 are connected to the upper sliding groove 18 and the lower sliding groove 22. Subsequently, the hydraulic cylinder 801 stops working, and the support frame 902 bears the mass of the workbench 5, so that the sliding seat 11 is separated from the sliding rail 4, which is convenient for cleaning and maintaining the sliding seat 11.

[0073] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all covered by the protection scope of the present invention.
