Technical Field

The utility model relates to a multipurpose choke plug tool, and belongs to the technical field of turning.

Background

When a drum is machined by a lathe (such as model CK 61315) produced in China, a double-top clamping is adopted by mainly utilizing a machine tool thimble, but generally, because the structure of the drum is that an inner hole is arranged in the middle of the drum, inner holes of two ends of the drum are required to be provided with inner hole plugs for clamping during machining, but because the types of the drums are more and the diameters of the inner holes of the drums are different, the inner hole of each drum is required to be provided with a corresponding plug, as shown in figures 1 and 4, because the sizes of the inner holes of the drums are changed, the size of the plug tool of the drum is different, the variety is various, for example, Chinese patent 201210280250.6 discloses a plug, but obviously, the plug can not solve the problem of multi-size adaptation; chinese patent 201720761718.1 discloses a bulkhead, but it is obvious that the bulkhead is adapted to different sizes of apertures by different claws, and the mechanical structure is complicated and the cost is high.

According to the situation, the multipurpose choke plug tool is designed, the number of the choke plug tools can be reduced, and the multipurpose choke plug tool is convenient to use and manage.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of overcoming the defects of the prior art and provides a multipurpose choke plug tool.

In order to solve the technical problems, the utility model provides a multipurpose bulkhead tool which comprises a fixed base and a bulkhead core body standing on one side of the fixed base, wherein shaft holes are formed in the axes of the fixed base and the bulkhead core body, and the bulkhead core bodies are formed by vertically stacking bulkheads with different sizes according to the size sequence.

The technical scheme of the utility model is further defined as follows:

furthermore, the main structure of the choke plug core body is step-shaped, and the outer diameter of each step corresponds to the inner diameter of an inner hole to be processed.

Further, the bulkhead core body structure is provided with at least 4 layers of step-shaped steps with the sizes phi 220 m6, phi 250 m6, phi 280 m6 and phi 310 m6 respectively.

Further, the inner diameters of inner holes to be processed corresponding to the main body structure of the 4-layer bulkhead core body are phi 220H7, phi 250H7, phi 280H7 and phi 310H 7.

Furthermore, the different sizes of the choke plug core body are matched according to the sizes of the inner holes at the two ends of the winding drum.

Further, the shaft hole is composed of a tapered hole and a cylindrical hole which are communicated up and down, the cylindrical hole is communicated with the small-diameter end of the tapered hole, the opening of the large-diameter end of the tapered hole is arranged in the side face of the outer side of the fixed base, and the cylindrical hole penetrates through the choke plug core body.

Further, the angle of both sides of the tapered hole is 60 °.

The utility model has the beneficial effects that: the number of actual choke plugs can be reduced, materials are saved, and management is facilitated.

Detailed Description

Example 1

In order to solve the problem that the choke plug tool is more, a multi-step choke plug tool is designed, and clamping and lathe machining of inner holes of different winding drums are facilitated. (see fig. 2) can be used for clamping the inner holes of four different drums.

The principle is shown in fig. 2 and 5: the utility model provides a multipurpose bulkhead frock, includes unable adjustment base and stands the bulkhead core of unable adjustment base one side, the axle center department of unable adjustment base and bulkhead core is equipped with the shaft hole, the bulkhead core is piled up from top to bottom according to big or small order by 4 not unidimensional end caps and is constituteed.

The choke plug core body structure is step-shaped, and the outer diameter of each step corresponds to the inner diameter of an inner hole to be processed.

The bulkhead core body structure is at least provided with 4 layers of step-shaped sizes phi 220 m6, phi 250 m6, phi 280 m6 and phi 310 m 6.

The different sizes of the choke plug core body are adapted according to the sizes of the inner holes at the two ends of the winding drum, and the inner diameters of the inner holes to be processed corresponding to the main body structures of the 4 layers of choke plug core bodies are phi 220H7, phi 250H7, phi 280H7 and phi 310H 7.

The shaft hole is composed of a tapered hole and a cylindrical hole which are communicated up and down, the cylindrical hole is communicated with the small-diameter end of the tapered hole, the large-diameter end opening of the tapered hole is arranged in the side face of the outer side of the fixed base, and the cylindrical hole penetrates through the choke plug core body. The angle of the two sides of the conical hole is 60 deg..

Fig. 3 is a schematic diagram of a winding drum to be processed, wherein inner holes at two ends of the winding drum are as follows: the sum of the phi 280H7,

when the model CK61315 is machined by a lathe, the choke plug tools shown in the figures are required to be arranged at two ends of the model CK61315 for clamping and machining, but because the winding drum belongs to a one-piece and small-batch production outline, winding drums of different models need choke plug tools matched with the inner hole, the choke plug tools of the winding drums are required to be prepared in different sizes and in various types, and according to the situation, the multi-purpose step choke plug tool shown in the figure 2 is designed, so that the number of the choke plug tools can be reduced, and the multi-purpose step choke plug tool is convenient to use and manage.
