Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a moving device for a numerical control machine tool. Background Art

[0002] CNC machine tools are automated machine tools equipped with a program control system. When the production line of a factory is improved or replaced, the existing machine tools need to be moved. However, CNC machine tools are large and heavy, and the static friction between the bottom of the CNC machine tools and the ground when pushed makes them difficult to move.

[0003] The prior art publication number CN201910962820.1 is a movable base plate of a machine tool, which includes a support plate, a mechanical jack, a fine threaded rod, a movable wheel, a screw and an adjustment sleeve. Two mechanical jacks are bolted to the bottom of the support plate. When in use, the machine body needs to be placed on the support plate. A connecting plate with four movable wheels is welded under the support plate. The height of the machine body is adjusted by adjusting the length of the mechanical jack. When the mechanical jack is shortened to a certain extent, the movable wheels contact the ground, and the machine tool can be moved at this time; the two sides of the machine body are fixed to the two splints by two fixing screws, and two movable nuts are welded on one side of the two splints. The two movable nuts are threadedly connected to the screw. An adjustment sleeve is fixed to one end of the screw. When the adjustment sleeve is rotated, the screw will drive the machine body to move through the movable nut, thereby adjusting the position of the machine body on the support plate.

[0004] However, when using this mobile base, the machine tool must be placed on the mobile base at all times, and there are fixing devices around it to keep the CNC machine tool stable on the ground. These fixing devices are set around the CNC machine tool, which increases the occupied area of ​​the entire equipment and affects the disassembly, movement, and installation processes of the CNC machine tool.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0006] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a moving device for a CNC machine tool, which can quickly move the CNC machine tool to a specified position through a detachably connected moving support plate. When the CNC machine tool does not need to be moved, the moving device can be removed at any time. It is easy to load and unload, and the simple structure makes it take up less space.

[0007] The above technical purpose of the present utility model is achieved through the following technical solutions: a moving device of a CNC machine tool, comprising a left support plate, a right support plate and a pulley, the left support plate and the right support plate are detachably connected, and the abutting surfaces of the left support plate and the right support plate both have grooves, and the two grooves are spliced ​​to form a through hole that passes through from top to bottom, and several pulleys are respectively threadedly connected to the bottom of the left support plate and the right support plate.

[0008] By adopting the above technical solution, it is necessary to first use a jack to lift the CNC machine tool to a height higher than the support plate, and then move the left support plate and the right support plate closer to the middle of the CNC machine tool from both sides. The through hole opened is just enough to accommodate the jack. After the docking is completed, the jack is removed, and the CNC machine tool is placed on the support plate. After pushing the CNC machine tool to the designated location, the jack is placed at the through hole position in the middle of the support plate. After lifting the CNC machine tool to a height, the support plate is removed, and the height of the jack is lowered until the CNC machine tool is in contact with the ground. The jack is removed to complete the movement of the CNC machine tool. The detachable assembly is convenient for loading and unloading the machine tool, and the simple design is convenient for use, placement and movement.

[0009] The utility model is further configured as follows: a clamping rod is fixedly connected to the two side walls of the right support plate close to the abutting surface, and a clamping hook is threadedly connected to the two side walls of the left support plate close to the abutting surface, and the inner wall of the clamping hook abuts against the side wall of the clamping rod.

[0010] By adopting the above technical solution, when the left and right support plates need to be connected, the clamping hook can be first abutted against the side wall of the clamping rod, and then the clamping hook can be locked on the side wall of the left support plate by turning the hexagonal stud with a wrench. The operation is simple and serves to connect the two support plates; when the left and right support plates do not need to be connected, the clamping hook can be rotated to the opposite direction of the clamping rod and locked to the side wall of the left support plate.

[0011] The utility model is further configured as follows: the left support plate and the right support plate are rotatably connected to a connecting rod at the middle position of the side walls symmetrical to the abutting surfaces; the connecting rod rotates around the rotating connection at an acute angle to the supporting surface on a plane perpendicular to the upper surface of the support plate; a handle is fixedly connected to the side of the connecting rod away from the rotating connection.

[0012] By adopting the above technical solution, when the connecting rod is used to rotate the moving device, the connecting rod forms a certain angle with the bottom surface, and the component force in the vertical direction offsets part of the gravity, reducing the static friction between the moving device and the ground, making it more convenient and labor-saving to move the machine tool, and also convenient for daily dragging and use.

[0013] The utility model is further configured as follows: the through hole is circular.

[0014] By adopting the above technical solution, the space for placing items is larger, the area of ​​a circle with the same circumference is maximized, and the edge of the circle has no sharp corners, which is convenient for placing items such as jacks.

[0015] The utility model is further configured as follows: the connecting rod is a trapezoidal plate.

[0016] By adopting the above technical solution, the force-bearing area of ​​the connecting rod during rotation is increased, the connection area between the lower end of the connecting rod and the rotating rod is larger, and the tensile strength and service life of the connecting rod are enhanced.

[0017] The utility model is further configured as follows: a groove is provided at the upper end of the through hole, and an end cover adapted thereto is provided on the groove.

[0018] By adopting the above technical solution, when the mobile device is used for daily transportation of items, the end cover can cover the middle through hole of the mobile device, making it easy to use.

[0019] The utility model is further configured as follows: the handle is covered with a rubber shell.

[0020] By adopting the above technical solution, when the CNC machine tool is moved using the connecting rod, the hand will grasp the handle, and the rubber increases the friction coefficient between the hand and the handle, making the handle easier to grasp.

[0021] The utility model is further configured as follows: the pulley is a universal wheel.

[0022] By adopting the above technical solution, the CNC machine tool can rotate 360 ​​degrees on the ground when the dynamic load or static load moves.

[0023] The utility model is further configured as follows: the upper surfaces of the left support plate and the right support plate are provided with textures such as stripes, grids, and convex dots.

[0024] By adopting the above technical solution, the friction between the CNC machine tool and the support plate surface is increased, making it less likely for the machine tool to slide out of the support plate range during movement.

[0025] In summary, the present invention has the following beneficial effects:

[0026] When moving a CNC machine tool, you only need to use a jack to lift the CNC machine tool, connect the two support plates from both sides, lower the jack to allow the CNC machine tool to land smoothly on the support plates for movement; after moving to the designated position, use the jack to lift the CNC machine tool from the middle through-hole position of the moving device, remove the two support plates, lower the jack to allow the CNC machine tool to land smoothly on the ground, and the CNC machine tool completes the movement and is placed at the designated position, and no fixing device occupies the space around the CNC machine tool.

[0033] The present invention will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] like Figures 1 to 4 The mobile device of a CNC machine tool shown in the figure includes a left support plate 1, a right support plate 2 and a pulley 3. The left support plate 1 and the right support plate 2 are detachably connected. There are grooves on the abutting surfaces of the left support plate 1 and the right support plate 2. The two grooves are spliced ​​to form a through hole 4 that passes through from top to bottom. Several pulleys 3 are respectively threadedly connected to the bottom of the left support plate 1 and the right support plate 2. A clamping rod 6 is fixedly connected to the two side walls of the right support plate 2 near the abutting surface. A clamping hook 5 is threadedly connected to the two side walls of the left support plate 1 near the abutting surface. The hook portion of the clamping hook 5 is connected to the clamping rod 6. The side walls of the left support plate 1 and the right support plate 2 are abutted against each other, and a connecting rod 7 is rotatably connected to the middle position of the side walls symmetrical to the abutting surface. The rotation axis of the connecting rod 7 is perpendicular to the line connecting the left support plate 1 and the right support plate 2. The connecting rod 7 is fixedly connected to a handle 8 on the side away from the rotating connection. The through hole 4 is circular, and the connecting rod 7 is a trapezoidal plate. A groove is provided at the upper end of the through hole 4, and an end cover 9 adapted thereto is provided on the groove. The handle 8 is covered with a rubber shell, and the pulley 3 is a universal wheel. The upper surfaces of the left support plate 1 and the right support plate 2 are provided with textures such as stripes, grids, and bumps.

[0035] When the utility model moves the CNC machine tool, the jack is first placed in the middle position of the groove at the bottom of the CNC machine tool, and then the jack is used to lift the CNC machine tool to a position where the bottom height of the machine tool is higher than the upper surface height of the left support plate 1 and the right support plate 2. Then the left support plate 1 and the right support plate 2 are brought together on the ground from both sides to the middle position under the CNC machine tool. At this time, the ends of the two support plates that are close to each other abut against each other to form a support plate. A through hole 4 that can accommodate the jack is provided in the middle position of the support plate. The jack is removed. At this time, the CNC machine tool abuts against the upper surface of the support plate as the jack falls. The upper surface of the support plate is provided with textures such as stripes, grids, and convex dots. The friction between the CNC machine tool and the support plate surface is increased, thereby increasing the connection strength between the CNC machine tool and the support plate during movement. After pushing the CNC machine tool to the designated location, the jack is placed at the through hole 4 in the middle of the support plate. The through hole 4 is circular. When the jack is placed at the through hole 4 position from any direction, it is at the same distance from the side wall of the through hole 4, which is convenient for placement. After the CNC machine tool is lifted up and left from the upper surface of the support plate, the support plate is withdrawn, and then the height of the jack is lowered to allow the CNC machine tool to fall smoothly to the ground. The jack is removed, and the CNC machine tool is moved and placed at the designated location, which solves the problem of excessive space occupied by the fixing device in the prior art.

[0036] A guide rail is provided under the roller. The guide rail is an auxiliary positioning device when the two support plates are docked, which is used to limit the movement of the support plates. A groove adapted to the roller is provided in the middle of the guide rail. A pair of fixing rods are fixedly connected between the two guide rails to keep the spacing between the guide rails consistent with the spacing of the rollers on both sides of the support plates. The guide rails have no connection with the ground and can be used and taken out at any time. When in use, the left support plate 1 and the right support plate 2 are moved from both sides along the guide rails to the middle of the CNC machine tool to complete the docking. When the CNC machine tool to be moved is large, the problem of docking difficulty caused by the limited docking field of view of the two support plates is solved.

[0037] The right support plate 2 is fixedly connected to the two side walls near the abutting surface with a clamping rod 6, and the left support plate 1 is threadedly connected to the two side walls near the abutting surface with a clamping hook 5, and the inner wall of the clamping hook 5 is in abutment with the side wall of the clamping rod 6. When the bottom area of ​​the CNC machine tool does not exceed the upper surface range of the support plate, the clamping hook 5 can be first abutted against the side wall of the clamping rod 6, and then the hexagonal stud can be turned with a wrench to lock the clamping hook 5 on the side wall of the left support plate 1, thereby connecting the two support plates; when the bottom area of ​​the CNC machine tool exceeds the upper surface range of the support plate, the two support plates do not need to be connected, and the clamping hook 5 can be rotated to the direction opposite to the clamping rod 6 and locked to the side wall of the left support plate 1, which does not affect the use of the moving device.

[0038] The left and right support plates 1 and 2 are rotatably connected to the middle position of the side walls symmetrical to the abutting surfaces, and the rotation axis of the connecting rod 7 is perpendicular to the line connecting the left and right support plates 1 and 2. When the connecting rod 7 is used to rotate the moving device, the connecting rod 7 forms a certain angle with the bottom surface, and the component force in the vertical direction offsets part of the gravity, reducing the static friction between the moving device and the ground, making it more convenient and labor-saving to move the machine tool, and also convenient for daily dragging. When the connecting rod 7 is a trapezoidal plate, the force area of ​​the connecting rod 7 during rotation is increased, and the connection area between the lower end of the connecting rod 7 and the rotating rod is larger, which enhances the tensile strength and service life of the connecting rod 7. The side of the connecting rod 7 away from the rotating connection is fixedly connected to a handle 8 for easy rotation of the connecting rod 7. The handle 8 is covered with a rubber shell. When the connecting rod 7 is used to move the CNC machine tool, the hand will grip the handle 8. The rubber increases the friction coefficient between the hand and the handle 8, making the handle 8 easier to grip.

[0039] A groove is provided at the upper end of the through hole 4, and an end cover 9 adapted thereto is provided on the groove. When the mobile device is used for daily transportation of articles, the end cover 9 can cover the middle through hole 4 of the mobile device, reducing the influence of the through hole 4 on the placement of articles and facilitating use.
