Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a bench drill with controllable turning angle. Background Art

[0002] A bench drill mainly refers to a machine tool that uses a drill bit to process holes on a workpiece. Many workpieces need to be drilled during production, so a bench drill is used. When drilling a workpiece, in addition to drilling holes in the vertical direction, a fixture needs to be installed on the table of the bench drill and then clamped by the fixture. The drill bit of the bench drill is raised and lowered to drill holes in the specified position of the workpiece. Currently, most bench drills adjust the drilling angle by rotating the column when in use. The pushing method has poor accuracy and requires repeated small angle adjustments to the rotating column to ensure the accuracy of the angle. The operation is relatively inconvenient and the adjustment efficiency is relatively low. It is highly dependent on human intervention. In order to solve this problem, a bench drill with controllable angle is proposed. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a bench drill with controllable angle, which is used to solve the problems of inconvenient operation, low efficiency and strong human dependence in traditional bench drills that adjust the drilling angle by rotating a column.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A bench drill with controllable rotation angle comprises a base and a column vertically rotatably connected in a fixed seat arranged on the base, a toothed disc is fixedly sleeved on the lower end surface of the column, a gear is meshed on one side of the toothed disc, an angle adjustment shaft is fixedly connected to the gear, and the angle adjustment shaft is rotatably connected to a shaft seat arranged on one side of the base, and an angle adjustment handwheel is fixedly connected to the angle adjustment shaft.

[0006] Preferably, the outer diameter of the toothed disc is the same as that of the gear and the shape and size of the teeth on the circumference are consistent.

[0007] Preferably, the angle adjustment hand wheel is a rubber-coated anti-slip wheel.

[0008] Preferably, the upper surface of the fixing seat is fixedly connected with a dial movably sleeved on the surface of the column, and a vertical reference line mark is provided at the position of the column surface corresponding to the dial.

[0009] Preferably, the distance between the column and the angle adjustment hand wheel is not less than 5CM.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model provides a toothed disc and a gear, and drives the gear on the angle adjustment shaft to rotate through the angle adjustment hand wheel, and drives the toothed disc meshing therewith to drive the column to rotate in the fixed seat, so as to realize the change of the column angle. At the same time, through the reference of the dial and the reference line marking, the angle is adjusted more accurately, which solves the problems of inconvenient operation, low efficiency and strong human dependence in the traditional bench drill to adjust the drilling angle by rotating the column.
