Description

Technical Field

[0001] The utility model relates to a height-adjustable vertical processing device, belonging to the technical field of processing machine tools. Background Art

[0002] Vertical machining equipment mainly refers to vertical machining machine tools or vertical machining centers. Its main feature is that the spindle axis is set perpendicular to the worktable, hence the name "vertical". Its main working principle is to fix the workpiece on the worktable and then cut in the direction of the spindle perpendicular to the worktable. The spindle is responsible for driving the milling cutter to rotate, and the worktable can move in the direction perpendicular to the spindle to achieve the cutting operation.

[0003] In existing designs, in order to improve applicability and facilitate use by workers of different heights, most of the workbenches of vertical processing equipment are designed as adjustable structures. For example, announcement number CN220161767U discloses a height-adjustable mechanical processing machine tool that can be adjusted by a single screw.

[0004] According to the applicant's investigation, during the processing of vertical processing equipment, the workbench often needs to bear a large vibration force, and the single-screw drive makes the supporting force all on one screw. This means that once the screw is damaged, the workbench is likely to fall, causing safety problems and delaying the processing process. In addition, there is no connection point at the top of the screw in this solution, which makes it more likely to be damaged due to vibration.

[0005] Therefore, in order to solve the above-mentioned problems of insufficient support strength and unsatisfactory stability, the applicant proposed a height-adjustable vertical processing equipment. Utility Model Content

[0006] The utility model aims to overcome the problems of insufficient support strength and unsatisfactory stability of vertical processing equipment in the prior art, and to provide a height-adjustable vertical processing equipment.

[0007] In order to achieve the above purpose / solve the above technical problems, the utility model is implemented by adopting the following technical solutions:

[0008] A height-adjustable vertical processing equipment, comprising an equipment table, a processing seat is installed on the top of the equipment table, a double-axis motor is installed at the bottom of the inner cavity of the processing seat, both sides of the double-axis motor are connected to the processing seat with a machine shaft, both sides of the top of the processing seat are rotatably connected with screw rods, the screw rods are connected to the protruding threaded holes at both ends of the lifting processing table, and the lifting processing table is connected to the machine shaft with a support part for locking the processing table;

[0009] The rotation of the machine shaft drives the two driving screws to rotate, so that the protrusion moves up and down the screws to adjust the height of the processing table.

[0010] Optionally, a soft pad is bonded to the side of the circular sleeve that contacts the moving block.

[0011] Optionally, a bevel gear is fixed to the non-threaded portion at one end of the two machine shafts, and another bevel gear meshing with each other is fixed to the bottom shaft of the screw rod passing through the inner cavity of the processing seat.

[0012] Optionally, two frame plates are installed on the top of the lifting processing table by screws, the top of the frame plates are rotatably connected with a spline sleeve, the bottom end of the spline sleeve is inserted with an adaptive spline shaft, and the spline shaft is fixed to the top surface of the screw rod.

[0013] Optionally, two guide rods are fixed to the top of the frame plate, the bottom of the guide rods is in contact with the top surface of the processing seat, and the guide rods pass through the corresponding sliding holes on the protrusions.

[0014] Optionally, a rectangular plug is fixed to the bottom of the guide rod, and the rectangular plug is inserted into the rectangular opening on the top surface of the processing seat.

[0015] Optionally, it is characterized in that a scale is provided on the surface of one of the guide rods.

[0016] Optionally, the supporting part includes a movable block sliding in a slideway at the bottom end of the inner cavity of the processing seat, the movable block is passed through the machine shaft and the two do not contact each other, the top end of the movable block and the bottom end of the lifting processing table are respectively rotatably connected to the two ends of the driving rod, and a round sleeve is fitted on one side of the movable block, and the round sleeve is threadedly sleeved on the external thread of the machine shaft.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model designs the supporting part so that the lifting processing table can be raised from the initial position when the height is adjusted. At this time, the driving rod will rotate and drive the moving block to move horizontally at the top of the moving block. After the adjustment is completed, the circular sleeve is rotated to make the threaded part on the outside of the machine shaft move horizontally, and finally it fits with the moving block. At this time, the moving block cannot move in the direction driven by the downward movement of the lifting processing table, so the lifting processing table is strengthened and supported. While strengthening the support by two lead screws, the supporting strength of the lifting processing table is further guaranteed, solving the problem of insufficient support strength by a single lead screw in comparative literature.

[0019] The utility model designs a spline sleeve, a frame plate, and a spline shaft. Before work, the two frame plates are installed on the top of the lifting processing table and are located on both sides of the screw rod. At this time, the spline shaft on the top surface of the screw rod is inserted into the spline sleeve to form an engagement. Then, when the screw rod rotates, the spline sleeve will also rotate, thereby providing an effective support point for the top of the screw rod and increasing the support strength of the two screw rods.

[0027] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0028] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0030] like Figure 1-Figure 6 As shown, the utility model provides a height-adjustable vertical processing equipment, including an equipment table 1, a processing seat 2 is installed on the top of the equipment table 1, a double-axis motor 3 is installed at the bottom end of the inner cavity of the processing seat 2, and a machine shaft 4 is connected to the processing seat 2 on both sides of the double-axis motor 3, and screw rods 5 are rotatably connected to both sides of the top of the processing seat 2, and the screw rods 5 are connected to the threaded holes of the protrusions 6 at both ends of the lifting processing table 7, and the lifting processing table 7 is connected to the machine shaft 4. The support part 9 includes a moving block 91 sliding in a slideway 94 at the bottom end of the inner cavity of the processing seat 2, and the moving block 91 is passed through by the machine shaft 4 and the two do not contact each other. The top of the moving block 91 and the bottom of the lifting processing table 7 are respectively rotatably connected to the two ends of the driving rod 93, and a round sleeve 92 is attached to one side of the moving block 91, and the round sleeve 92 is threadedly sleeved on the external thread of the machine shaft 4, and the machine shaft 4 drives the two screw rods 5 to rotate by rotation, and the side of the round sleeve 92 that is attached to the moving block 91 is bonded with a soft pad 95, and the soft pad 95 is made of silicone.

[0031] By designing the support part 9, the double-axis motor 3, the machine shaft 4 and the two screw rods 5, when the height is adjusted, the double-axis motor 3 is started to rotate the machine shafts 4 at both ends, so that the two screw rods 5 rotate together. It should be noted that the threads of the screw rods on both sides are opposite, and then the protrusion 6 drives the lifting table 7 to adjust the height. When the lifting table 7 rises, the driving rod 93 will rotate and drive the moving block 91 to move horizontally on the top surface of the slideway 94. After the adjustment is completed, the circular sleeve 92 is rotated to make the threaded part of the machine shaft 4 move horizontally, and finally it fits with the moving block 91. At this time, the moving block 91 cannot be lifted or lowered. The processing table 7 moves in the direction driven by the downward movement, and the lifting processing table 7 is reinforced and supported, which ensures the supporting strength of the lifting processing table 7, and the soft pad 95 prevents the round sleeve 92 and the moving block 91 from being squeezed too tightly, resulting in difficulty in separation. It should be noted that the limited sliding of the moving block 91 on the top surface of the slide 94 is a prior art. For example, the convex sliding block at the bottom of the moving block 91 slides in the slide 94, and the locking of the machine shaft 4 when the dual-axis motor 3 is turned off is also a prior art design method, such as through a brake, etc., and some springs are connected to the top surface of the processing seat 2 at the bottom of the lifting processing table 7 for auxiliary support, which is not limited here.

[0032] In this embodiment, a bevel gear 8 is fixed to the unthreaded portion at one end of the two machine shafts 4, and a bevel gear 8 is also fixed to the bottom shaft of the screw rod 5 passing through the inner cavity of the processing seat 2, and the two bevel gears 8 are meshed with each other.

[0033] To further explain, by designing the bevel gear 8, when the machine shaft 4 rotates, the bevel gear 8 on the machine shaft 4 meshes with the bevel gear 8 connected to the bottom shaft of the screw rod 5, and then the two screw rods 5 can be driven to rise and fall by one motor. Compared with the single screw rod 5 drive support, the support strength can be enhanced to a certain extent without adding additional electrical equipment.

[0034] Depend on Figure 1-Figure 3 as well as Figure 6 It is shown that two frame plates 10 are installed on the top of the lifting processing table 7 by screws, and the top of the frame plate 10 is rotatably connected with a spline sleeve 12, and an adapted spline shaft 11 is inserted into the bottom end of the spline sleeve 12, and the spline shaft 11 is fixed on the top surface of the screw rod 5.

[0035] By designing the spline sleeve 12, the frame plate 10, and the spline shaft 11, before work, the two frame plates 10 are installed on the top of the lifting processing table 7 and located on both sides of the screw rod 5. At this time, the spline shaft 11 on the top surface of the screw rod 5 is inserted into the spline sleeve 12 to form an engagement. Then, when the screw rod 5 rotates, the spline sleeve 12 will also rotate, thereby providing an effective support point for the top of the screw rod 5 and increasing the support strength of the two screw rods 5.

[0036] In this embodiment, two guide rods 13 are fixed to the top of the frame plate 10, the bottom of the guide rods 13 is in contact with the top surface of the processing seat 2, and the guide rods 13 pass through the corresponding sliding holes on the protrusions 6, and a rectangular plug block 14 is fixed to the bottom of the guide rods 13, and the rectangular plug block 14 is inserted into the rectangular opening on the top surface of the processing seat 2. A scale 15 is provided on the surface of the guide rod 13, and the scale 15 is connected to the surface of the guide rod 13 by spraying.

[0037] The two guide rods 13 can provide guidance for the lifting of the lifting processing table 7 and enhance the stability of the screw rod 5 driving the lifting. The rectangular plug 14 is inserted into the top opening of the processing seat 2 after the installation of the frame plate 10 is completed, so that the frame plate 10 has better stability and better connection strength with the processing seat 2. Finally, the scale 15 can enhance the adjustment accuracy by observing the numerical value, which is very practical.

[0038] Working principle: When in use, first install the two frame plates 10 on the top of the lifting processing table 7 and on both sides of the screw rod 5. At this time, the spline shaft 11 on the top surface of the screw rod 5 is inserted into the spline sleeve 12 to form an engagement, and the guide rod 13 passes through the corresponding sliding hole on the protrusion 6. Then, when adjusting the height, the double-axis motor 3 is started to rotate the machine shaft 4 at both ends. At this time, the bevel gear 8 on the machine shaft 4 is engaged with the bevel gear 8 connected to the bottom shaft of the screw rod 5, so that the two screw rods 5 rotate together, and then the protrusion 6 drives the lifting processing table 7 to adjust the height. When the lifting processing table 7 rises, the driving rod 93 will rotate and drive the moving block 91 to move horizontally at the top of the slideway 94. After the adjustment is completed, the circular sleeve 92 is rotated to make the threaded part on the outside of the machine shaft 4 move horizontally, and finally it fits with the moving block 91. At this time, the moving block 91 cannot move in the direction driven by the downward movement of the lifting processing table 7 to complete the height adjustment work.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
