Description

Technical Field

[0001] The utility model relates to a reaming guide sleeve for a swash - axis motor base plate drilling machine. Background Art

[0002] A reamer is a rotary cutting tool with one or more cutting teeth, used to remove a thin layer of metal from the surface of a machined hole. The reamer is a rotary finishing tool with straight or spiral cutting edges, used for enlarging or finishing holes. Since the cutting amount of the reamer is small, its machining accuracy requirements are usually higher than those of a drill bit. It can be operated manually or installed on a drilling machine for work.

[0003] When operating the reamer manually, due to the lack of guidance at the front end of the reamer, the size and geometric tolerance after reaming exceed the standard, increasing the instability of the product. Therefore, it is necessary to design a guiding part to assist the operator in operating the reamer. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above - mentioned deficiencies of the prior art and provide a reaming guide sleeve for a swash - axis motor base plate drilling machine.

[0005] A reaming guide sleeve for a swash - axis motor base plate drilling machine includes a reamer, a workpiece, and a guide sleeve. There is a hole to be machined on the workpiece. The guide sleeve is a cylinder, and its upper end surface is provided with a guide hole having the same diameter as the hole to be machined. The guide sleeve is fixed on the workpiece, and the guide hole is aligned with the hole to be machined.

[0006] Preferably, the guide sleeve is of a cylindrical structure.

[0007] Preferably, at least two fixing holes are provided on the upper end surface of the guide sleeve, and corresponding connecting holes are provided on the workpiece near the hole to be machined. The guide sleeve and the workpiece are connected by a positioning pin passing through the fixing holes and the connecting holes.

[0008] Preferably, the number of fixing holes is two, and the included angle between the connecting lines of the centers of the two fixing holes and the guide hole is greater than 90°.

[0009] Beneficial Effects: Compared with the prior art, the utility model limits the movement trajectory of the reamer through the guide sleeve, assisting the staff in reaming, effectively improving the cylindricity after reaming, and ensuring the stability during reaming. The use of the guide sleeve can make the reamer more accurately positioned, and the guide sleeve is easy to install and replace, reducing the number of adjustments during the reaming process, improving the work efficiency and the stability of the reamed holes of the product, providing a more efficient and accurate solution for the processing of the base plate. Description of the Drawings

[0010] Figure 1 It is an exploded view of a reaming guide sleeve for a swash - axis motor base plate drilling machine;

[0011] In the figure, 1 is a reamer, 2 is a guide sleeve, and 3 is a workpiece. Detailed implementation mode

[0012] In order to deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0013] As Figure 1 shown, reamer 1, guide sleeve 2, workpiece 3;

[0014] An inclined shaft motor base drilling reaming guide sleeve includes a reamer 1, a workpiece 3, and a guide sleeve 2. The workpiece 3 is provided with a hole to be machined. The guide sleeve 2 is a cylinder, and its upper end surface is provided with a guide hole having the same diameter as the hole to be machined. The guide sleeve 2 is fixed on the workpiece 3, and the guide hole is aligned with the hole to be machined.

[0015] In this embodiment, the guide sleeve 2 has a cylindrical structure.

[0016] In this embodiment, two fixing holes are provided on the upper end surface of the guide sleeve 2. The included angle between the connecting lines of the centers of the two fixing holes and the guide hole is 180°. Corresponding connecting holes are provided on the workpiece 3 near the hole to be machined. The guide sleeve 2 and the workpiece 3 are connected by positioning pins passing through the fixing holes and the connecting holes.

[0017] It should be noted that the purpose of providing two fixing holes is to ensure the stable connection between the guide sleeve 2 and the workpiece 3 and ensure that the guide sleeve 2 does not shake. Above this, machining more than two holes can also achieve the same purpose.

[0018] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
