Abstract
The utility model discloses a deep-hole thread machining tool which comprises a connecting rod (1) and a Morse taper shank (2) arranged at one end of the connecting rod (1). An installation hole (4) for containing a standard screw tap sleeve (3) is formed in the other end of the connecting rod (1), the installation hole (4) and the Morse taper shank (2) are coaxially arranged, and at least one set screw (5) is arranged on the hole wall of the installation hole (4). The Morse taper shank (2) and the connecting rod (1) are an integrally-formed integral piece, the connecting rod (1) is a cylindrical shaft, and the Morse taper shank (2) and the cylindrical connecting rod (1) are coaxially arranged. The Morse taper shank (2) is a No. four Morse taper shank. By means of the deep-hole thread machining tool, the requirement for the coaxiality of a screw tap and a drilling spindle can be met, a plurality of kinds of products can be machined, the universality of the tool is improved, and the manufacturing cost of the deep-hole thread machining tool is low.
Description
Technical field
The utility model relates to the instrument for machining screw in a kind of mechanical field, particularly relates to a kind of machining tool of deep hole thread.
Background technology
At deep hole processing screw thread, for example, while processing main line direct current motor base brush carrier screwed hole, due to screwed hole positional distance radial drilling machine main tapping distance, and screwed hole position and support wall close together, therefore the main tapping of drilling machine in the time of machining screw and support wall produce interfere, cause the screwing tool of general structure can not meet instructions for use.
Because the position of screwed hole is darker, existing screwing tool adopts the round steel bar of φ 30 conventionally, Morse taper shank and conventional screw tap are welded on respectively to round steel bar two ends, are then connected with drill press spindle by Morse taper shank, make screw tap meet processing request by the lengthening of round steel bar.
In use there is the shortcoming of following two aspects in the screwing tool of said structure, on the one hand, due to the distortion in the time welding of Morse taper shank, screw tap and round steel bar, therefore cannot ensure the axiality requirement of screw tap and Morse taper shank and drill press spindle, although use this instrument can meet processing request cannot to ensure the qualification rate of product; On the other hand, owing to being Welding Structure, therefore a kind of instrument can only be processed corresponding a kind of screwed hole, and converted products is single, lack of diversity.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of axiality requirement that can ensure screw tap and drill press spindle is provided, and can process again multiple product, increases the versatility of instrument, and the deep hole thread machining tool of low cost of manufacture.
For solving the problems of the technologies described above, the utility model adopts so a kind of deep hole thread machining tool, comprise connecting rod and the Morse taper shank that is arranged on this connecting rod one end, be provided with one for placing the installing hole of die hob cover at the other end of connecting rod, this installing hole and Morse taper shank are coaxially set, and are provided with at least one holding screw on the hole wall of described installing hole.
As a kind of preferred embodiment of the present utility model, described Morse taper shank and connecting rod are integrated a single piece of making, and described connecting rod is cylindrical shaft, and described Morse taper shank and cylindrical connecting rod are coaxially set.
In the utility model, described holding screw has two and along the axis of installing hole between the upper and lower every setting.
In the utility model, described Morse taper shank is No. 4 taper shanks of Mohs.
Adopt after said structure, the utlity model has following beneficial effect:
The utility model is in the time of work, because Morse taper shank is connected with drill press spindle coaxial line, be placed in installing hole screw tap and die hob cover coaxial line, again because installing hole and Morse taper shank are coaxially set, therefore effectively ensured the axiality requirement of screw tap and drill press spindle, meet well processing request, ensured the qualification rate of product.
Owing to can place die hob cover and the screw tap of different size specifications in installing hole, therefore, a kind of instrument can be processed the screwed hole of multiple different specification size, has increased the versatility of instrument, has expanded the scope of application of instrument, has saved processing cost.In addition, manufacturing cost of the present utility model is also lower.
Brief description of the drawings
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model deep hole thread machining tool, holding screw not shown in the figures.
Fig. 2 is a kind of structural representation that the utility model deep hole thread machining tool is arranged on processing work on drill press spindle.
Detailed description of the invention
Referring to a kind of deep hole thread machining tool shown in Fig. 1,2, comprise connecting rod 1 and the Morse taper shank 2 that is arranged on this connecting rod 1 one end, be provided with one for placing the installing hole 4 of die hob cover 3 at the other end of connecting rod 1, this installing hole 4 is coaxially set with Morse taper shank 2, is provided with at least one holding screw 5 on the hole wall of described installing hole 4.
As a kind of preferred embodiment of the present utility model, as shown in Figure 1, 2, described Morse taper shank 2 is integrated with connecting rod 1 single piece of making, and described connecting rod 1 is cylindrical shaft, and described Morse taper shank 2 is coaxially set with cylindrical connecting rod 1.
Holding screw 5 described in the utility model preferably has two and along the axis of installing hole 4 between the upper and lower every setting, as shown in Figure 2.
In the utility model, described Morse taper shank 2 is preferably No. 4 taper shanks of Mohs.
Referring to Fig. 2, adopt a kind of structural representation of radial drilling machine deep hole processing screw thread 7 on workpiece 6.First screw tap 8 is inserted in die hob cover 3, then the die hob cover 3 assembling is placed in installing hole 4, and undertaken fasteningly by holding screw 5, then Morse taper shank 2 is inserted in the mohs tapered bore 9-1 of drill press spindle 9, starting drilling machine power supply can process.
Through on probation, the utility model can ensure the machining accuracy of screw thread, and can be common to M12 metric thread, 1/2, and " processing of the above screw thread of inch screw thread has obtained good practical function.
