Technical Field
[0001] The utility model relates to the technical field of mechanical equipment, and more specifically, to a simple tapping machine. Background Art
[0002] During machining, it is occasionally necessary to manually tap the workpiece. Usually, the workpiece needs to be clamped and fixed on the work platform first, and then a tap of corresponding specifications is used for manual tapping. However, since the tap is controlled manually by the operator, the verticality cannot be guaranteed, resulting in axial offset in tapping and large processing errors. Based on this, the utility model proposes a simple tapping machine. Utility Model Content
[0003] The utility model aims to overcome the deficiencies in the prior art and provide a simple tapping machine, which has the characteristics of simple structure, convenient operation and high tapping precision.
[0004] To solve the above technical problems, the purpose of the utility model is achieved as follows: the utility model involves a simple tapping machine, including a working platform, a rear-arranged column is provided on the working platform, a cantilever is provided on the column, a guide cylinder is provided on the cantilever, a guide column for up and down movement is slidably connected in the guide cylinder, a drill chuck is provided at the lower end of the guide column, and a lever structure for controlling its rotation is provided at the upper end, a rolling bearing sleeved on the guide column is provided below the lever structure, the inner ring of the rolling bearing is fixed on the guide column, a protective sleeve for follow-up is provided on the outer ring of the rolling bearing, the bottom of the protective sleeve has a folded edge for covering the rolling bearing, and the guide column is also sleeved with a compression spring with one end against the guide cylinder and the other end against the folded edge.
[0005] The utility model is further configured as follows: the pulling structure comprises a side hole opened on the guide column, the side hole extends along the radial direction of the guide column, and a pulling rod moving along the axial direction is passed through the side hole.
[0006] The utility model is further configured as follows: the rolling bearing is a deep groove ball bearing.
[0007] In summary, the utility model has the following beneficial effects: the simple tapping machine involved in the utility model ensures the verticality of the tap during feeding through the setting of the guide cylinder and the guide column, prevents axial deviation, improves tapping accuracy, has a simple structure, is easy to operate, has complete overall functions, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 2 It is a partial structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0010] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.
[0011] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0012] Example 1
[0013] See also Figure 1 and Figure 2 As shown, a simple tapping machine involved in this embodiment includes a working platform 1, on which a column 2 arranged at the rear is provided, on which a cantilever 3 is provided, on which a guide cylinder 4 is provided, in which a guide column 5 is slidably connected for moving up and down is provided, a drill chuck 6 is provided at the lower end of the guide column 5, and a lever structure for controlling its rotation is provided at the upper end, and a rolling bearing 7 sleeved on the guide column 5 is provided below the lever structure, the inner ring of the rolling bearing 7 is fixed on the guide column 5, and on the outer ring of the rolling bearing 7 is provided a sleeve 8 for following, and the bottom of the sleeve 8 has a folded edge 9 for covering the rolling bearing 7, and the guide column 5 is also sleeved with a compression spring 10 with one end against the guide cylinder and the other end against the folded edge.
[0014] Furthermore, the pulling structure includes a side hole (not shown) opened on the guide column 5, the side hole extends in the radial direction of the guide column 5, and a pulling rod 11 that moves in the axial direction passes through the side hole.
[0015] Furthermore, the rolling bearing 7 is a deep groove ball bearing.
[0016] In this embodiment, the workpiece to be tapped is first fixed with a bench vise and placed on the work platform 1, and then a tap of corresponding specifications is clamped on the drill chuck 6, the working position is adjusted, and then the lever 11 is used to drive the guide column 5 to rotate and move downward at the same time until the tap on the drill chuck 6 touches the workpiece, and continues to move downward until the tapping is completed, and finally the guide column 5 is reset.
