Description

Technical Field

[0001] The utility model relates to the field of lathe processing, in particular to a turning device for broach processing. Background Art

[0002] A broach is a forming tool used for broaching. There are multiple rows of teeth on the surface of the tool. The size and shape of each row of teeth increase and change successively from the cutting entry end to the cutting exit end. When the broach performs broaching movement, each tooth cuts a certain thickness of metal from the workpiece, and finally obtains the required size and shape. Broaches are often used to process round holes, spline holes, keyways, planes and forming surfaces in batch and mass production. Broaches are usually made of high-speed steel as a whole, and can also be made into a modular type. Carbide broaches are generally modular. Usually, cylindrical broaches are mostly processed by turning the teeth on a lathe.

[0003] However, since a large amount of waste chips are generated during turning and broaching, the waste chips will splash outward under the action of centrifugal force, affecting the machining operation. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a turning device for broach processing, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a turning device for broach processing, comprising a lathe, a first mounting seat and a second mounting seat are respectively arranged on both sides of the upper end of the lathe, a guide rod is connected between the first mounting seat and the second mounting seat, a turning mechanism is installed on the outer side of the guide rod, a protective mechanism is arranged on one side of the upper end of the turning mechanism, the protective mechanism comprises: a first arc sleeve and a second arc sleeve, an air duct is installed inside the first arc sleeve, a strong magnetic pad is arranged on the inner side wall of the first arc sleeve, a threaded rod is arranged between the outer side of the first arc sleeve and the turning mechanism, and a threaded sleeve is installed on the outer side of the threaded rod.

[0006] As a further solution of the utility model: the turning mechanism includes: a moving seat, a cutting tool, and a direction-adjusting seat.

[0007] As a further solution of the utility model: a three-jaw chuck is installed on the first mounting seat at a side close to the protective mechanism, a ejector mechanism is installed inside the second mounting seat, and a positioning knob is installed on the upper surface of the second mounting seat.

[0008] As a further solution of the present invention: an elastic rotating shaft is installed between the second circular arc sleeve and the first circular arc sleeve, and the first circular arc sleeve and the second circular arc sleeve are both made of magnetic material components.

[0009] As a further solution of the utility model: the outer end of the air duct is connected to a negative pressure source, and a filter is installed on the inner side of the upper end of the air duct.

[0010] As a further solution of the utility model: the turning mechanism is movably connected to the guide rod through the movable seat.

[0011] As a further solution of the utility model: the threaded rod is meshed and rotatably connected with the threaded sleeve.

[0012] As a further solution of the utility model: the center position of the three-jaw chuck coincides with the center position of the ejector mechanism.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The waste chips generated by cutting will be blocked by the first arc sleeve and the second arc sleeve. At the same time, the negative pressure outside the air duct will absorb the waste chips to the lower position. The strong magnetic pad will absorb the waste chips to prevent the waste chips from splashing and affecting the processing.

[0015] 2. By applying torque to the threaded sleeve and controlling the spacing between the two threaded rods, the installation positions of the first arc sleeve and the second arc sleeve on the outside of the raw material can be selected. The protection mechanism can be controlled to the installation position of raw materials with different outer diameters during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 2-3 As shown, in this embodiment, the turning mechanism 4 includes: a moving seat 401, a cutting tool 402, and an adjusting seat 403. The turning mechanism 4 is movably connected to the guide rod 5 through the moving seat 401. The first mounting seat 2 is located on the side close to the protective mechanism 6 and is equipped with a three-jaw chuck 7. The second mounting seat 3 is internally equipped with an ejector mechanism 9. The center position of the three-jaw chuck 7 coincides with the center position of the ejector mechanism 9. A positioning knob 8 is installed on the upper surface of the second mounting seat 3. The distance between the ejector mechanism 9 and the three-jaw chuck 7 can be adjusted by adjusting the tightness of the positioning knob 8. The three-jaw chuck 7 and the ejector mechanism 9 can be controlled to position broaches of different lengths.

[0025] The working principle of the utility model is as follows: according to the length of the outer diameter of the raw material to be placed, the installation height of the protective mechanism 6 above the turning mechanism 4 is selected and adjusted, and the installation positions of the first arc sleeve 601 and the second arc sleeve 602 on the outside of the raw material are selected by applying torque to the threaded sleeve 606 and controlling the spacing between the two threaded rods 605. The second arc sleeve 602 is opened as a whole with the first arc sleeve 601 through the action of the elastic rotating shaft, and the raw material to be processed is placed between the ejector mechanism 9 and the three-jaw chuck 7 for fixing, so that the second arc sleeve 602 covers the first arc sleeve 601 as a whole. After the movable seat 401 is slid above the guide rod 5 to the position where the teeth need to be cut, the adjusting seat 401 is used to adjust the teeth. 03 Adjusting the angle of the cutting tool 402 will contact the raw material, and the gap between the first circular arc sleeve 601 and the second circular arc sleeve 602 is for the cutting tool 402 to pass through for cutting. During processing, the three-jaw chuck 7 as a whole drives the raw material to rotate, and the turning mechanism 4 as a whole moves on the outside of the guide rod 5, and the cutting tool 402 cuts the tooth groove. When the turning mechanism 4 moves as a whole, it will drive the protective mechanism 6 to move on the outside of the raw material. The waste chips generated by cutting will be blocked by the first circular arc sleeve 601 and the second circular arc sleeve 602. At the same time, the negative pressure on the outside of the air duct 604 will absorb the waste chips to the lower position, and the set strong magnetic pad 603 will absorb the waste chips to prevent the waste chips from splashing and affecting the processing.
