Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of numerical control drilling machines, in particular to a moving mechanism for a processing table of a numerical control drilling machine. Background Technique
[0002] The processing table in a numerical control drilling machine is a platform fixed above the machine tool. The processing table provides a reliable support plane for clamping and fixing the workpiece to be processed, ensuring the stability of the workpiece during the processing. The moving structure of the processing table is a key component of the numerical control drilling machine, generally composed of components such as a servo motor, a screw rod, a slider, and a guide rail.
[0003] During the processing of the numerical control drilling machine, a large amount of metal chips are also generated on the processing table. The driving screw rod of the processing table is exposed to the outside during use, and metal chips may accumulate on the thread surface, forming granular abrasives, causing additional friction when the screw rod contacts the nut, resulting in wear, corrosion, and deterioration of the screw rod surface, shortening the service life of the equipment components. For this reason, we propose a moving mechanism for a processing table of a numerical control drilling machine to solve the existing problems. Content of the Utility Model
[0004] The purpose of the utility model is to propose a moving mechanism for a processing table of a numerical control drilling machine aiming at the problems existing in the background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A moving mechanism for a processing table of a numerical control drilling machine, including a mounting frame, a support plate, a telescopic tube, a processing table, and a nut. A support plate is arranged inside the mounting frame, a processing table is arranged above the support plate, a three-jaw chuck is arranged at the upper end of the processing table, symmetrically distributed guide rails are arranged at the upper end of the support plate, symmetrically distributed sliders are arranged at the lower end of the processing table and are slidably installed on the outer wall of the guide rails, symmetrically distributed bearing supports are arranged at the upper end of the support plate, a motor I is arranged at one end of the bearing support, a screw rod rotatably installed inside the bearing support is arranged at the output end of the motor I, a nut rotatably sleeved on the outer wall of the screw rod is arranged at the lower end of the processing table, and two groups of equidistantly distributed and annular telescopic tubes and blocking cloths are arranged on the outer wall of the screw rod, and the telescopic tubes and the blocking cloths are distributed at intervals.
[0006] When using a moving mechanism for a machining table of a numerically controlled drilling machine in this solution, when the first motor drives the screw to rotate, since the machining table slides on the guide rail through the slider, the machining table is slidingly guided. The workpiece is clamped by the three-jaw chuck, the nut is pushed by the screw, and the machining table and the clamped workpiece follow the machining table for position adjustment. The mounting bracket is fixed to the numerically controlled drilling machine through support. When the nut moves, it squeezes the telescopic tube and the blocking cloth, so that two groups of equally spaced telescopic tubes and blocking cloths, one group is stretched and the other group is squeezed, so that when the screw is used, the telescopic tube and the blocking cloth intercept the debris generated during machining, preventing the debris from entering the outer wall of the screw and then squeezing and rubbing against the nut. After the workpiece is machined, the second motor drives the rotating shaft to rotate, driving the support plate to tilt, and the support plate and the remaining metal debris on the machining table are dumped, providing assistance during debris cleaning.
[0007] Preferably, both ends of the support plate are provided with rotating shafts rotatably installed inside the mounting bracket, and one end of the mounting bracket is provided with a second motor whose output end is connected to the rotating shaft. The two rotating shafts of the support plate are rotatably supported inside the mounting bracket.
[0008] Preferably, a side plate is provided at the rear side of the lower end of the support plate, which fits against the inner wall of the lower end of the mounting bracket. The side plate supports the bottom of the rear side of the lower end of the support plate, ensuring the stability of the support plate during workpiece machining.
[0009] Preferably, the lower end of the mounting bracket is provided with symmetrically distributed brackets, and mounting grooves are respectively opened inside the brackets. The mounting bracket is installed through the brackets, and the mounting grooves are used for the insertion of fixing parts.
[0010] Preferably, both ends of the telescopic tube are respectively connected to the bearing support and the nut.
[0011] Preferably, through holes are arranged in the nut in an annular array, and guide rods fixedly connected to the bearing support are slidably inserted inside the through holes. The nut is slidingly guided by the guide rods.
[0012] Preferably, both the blocking cloth and the telescopic tube are located outside the guide rod. This prevents the blocking cloth between the telescopic tubes from falling down and contacting the screw.
[0013] Preferably, discharge ports are respectively opened inside the lower ends of the guide rails. When the support plate tilts, the debris can effectively slide down from one side of the debris box through the discharge ports.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] 1. The utility model provides a telescopic tube on the outer wall of the screw of the processing table moving mechanism of the CNC machine tool. The telescopic tubes are equidistantly distributed on the barrier cloth and are connected to both ends of the nut. The telescopic tube and the barrier cloth form a protective structure. The opposite end and the opposite end of the protective structure are fixed. When the nut moves, the telescopic tube and the barrier cloth are squeezed to make the protective structure retract or extend. Due to the addition of the barrier cloth, the protective structure occupies a small space for extrusion and storage and has a large extension length, which prevents metal debris from entering the nut and the screw thread raceway, and effectively protects the moving mechanism of the processing table.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] like Figures 1 - 5As shown in the figure, a moving mechanism for the processing table of a numerically controlled drill press proposed by the present utility model includes a mounting frame 1, a support plate 2, telescopic tubes 10, a processing table 12, and a nut 15. A support plate 2 is arranged inside the mounting frame 1, a processing table 12 is arranged above the support plate 2, a three-jaw chuck 11 is arranged at the upper end of the processing table 12, symmetrically distributed guide rails 7 are arranged at the upper end of the support plate 2, symmetrically distributed sliders 6 that are slidably mounted on the outer walls of the guide rails 7 are arranged at the lower end of the processing table 12, symmetrically distributed bearing supports 9 are arranged at the upper end of the support plate 2, a first motor 3 is arranged at one end of the bearing support 9, a screw rod 19 rotatably mounted inside the bearing support 9 is arranged at the output end of the first motor 3, a nut 15 rotatably sleeved on the outer wall of the screw rod 19 is arranged at the lower end of the processing table 12, two groups of equally spaced and annular telescopic tubes 10 and a blocking cloth 17 are arranged on the outer wall of the screw rod 19, and the telescopic tubes 10 and the blocking cloth 17 are spaced apart;
[0024] Both ends of the telescopic tube 10 are respectively connected to the bearing support 9 and the nut 15;
[0025] Annularly arrayed through holes 16 are formed inside the nut 15, and guide rods 18 fixedly connected to the bearing support 9 are slidably inserted inside the through holes 16;
[0026] Both the blocking cloth 17 and the telescopic tube 10 are located outside the guide rod 18;
[0027] Based on the implementation steps of Embodiment 1: When the first motor 3 drives the screw rod 19 to rotate, the processing table 12 is slidably guided through the sliders 6 on the guide rails 7, and the workpiece is clamped by the three-jaw chuck 11. As the screw rod 19 pushes, the nut 15 adjusts the position of the processing table 12 and the clamped workpiece. The movement of the nut 15 compresses or extends the two groups of equally spaced telescopic tubes 10 and the blocking cloth 17. One group is lifted and the other group is squeezed. This design enables the telescopic tubes 10 and the blocking cloth 17 to intercept the debris generated during processing during the use of the screw rod 19, thereby preventing the debris from entering the outer wall of the screw rod 19.

[0031] An exhaust port 14 is provided inside the lower end of each of the guide rails 7;
[0032] In this embodiment, after the workpiece machining is completed, when the motor two 4 drives the rotating shaft 8 to rotate, the support plate 2 inclines, dumping the residual metal chips on the machining table 12. By driving the inclination of the support plate 2 through the rotation of the motor two 4, the residual metal chips on the machining table 12 can be conveniently and quickly removed, reducing the time and cost of manual cleaning and reducing the difficulty of maintenance and cleaning.
