AI Technical Summary

Technical Problem

The existing deep-hole drilling machine fixtures have debris problems that are similar to those of the outer circle but require replacement of different top plates, which affects the processing quality and efficiency.

Method used

A deep-hole drilling machine fixture is designed, including sleeve, bolt flange, sliding sleeve, elastic top ring, spring, guide sleeve and top disk. Through the combination of the workpiece and the 45° top disk, the workpiece is tightened by the force generated by the oil cylinder or lead screw, and the guide sleeve is close to the end surface of the workpiece, reducing the chip-splitting phenomenon, and allowing workpieces with similar outer diameters to use the same top disk.

Benefits of technology

This design improves the fixing stability of the workpiece, reduces the occurrence of debris, and allows the use of the same top disk to process workpieces with similar outer diameters, improving machining efficiency and quality.

Description

Technical Field

[0001] The utility model relates to the technical field of drilling machine clamps, in particular to a clamp for a deep hole drilling machine. Background Art

[0002] A deep hole drilling machine is a machine tool used for drilling deep holes. Different from the traditional hole processing method, it mainly relies on specific drilling technology (such as gun drilling, BTA drilling, ejector drilling, etc.) to drill deep holes with a length-to-diameter ratio greater than 10 and precision shallow holes. The deep hole drilling machine has the characteristics of high precision, high efficiency and high consistency, and can easily process various forms of deep holes, including cross holes, inclined holes, blind holes and flat-bottomed blind holes.

[0003] The deep hole drilling machine fixture is used to fix the workpiece on the deep hole drilling machine. It can ensure the position accuracy and stability of the workpiece during the processing, thereby ensuring the processing quality and efficiency;

[0004] Existing deep hole drilling machine fixtures often have problems such as debris and the need to replace different top plates even if the outer circles are similar. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a clamp for a deep hole drilling machine, which solves the problems mentioned in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixture for a deep hole drilling machine, comprising a sleeve, a bolt flange is fixedly installed on the outer side of the sleeve, a sliding sleeve is sleeved inside the sleeve, an elastic top ring for the hole is also fixedly installed on the end of the sliding sleeve away from the bolt flange, a spring is also fixedly installed between the sleeve and the sliding sleeve, a guide sleeve is also sleeved on the outer side of the sliding sleeve, and a top plate is fixedly installed on the end of the sleeve away from the bolt flange.

[0007] As a preferred technical solution of the utility model, the bolt flange is also provided with bolt holes, and six bolt holes are provided.

[0008] As a preferred technical solution of the utility model, one end of the sleeve close to the bolt flange is also provided with a through hole for passing a drill bit of a drill gun.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. The utility model combines the workpiece with the 45° top plate inclined surface, and the workpiece is pressed tightly by the force generated by the oil cylinder or the lead screw at the rear end of the workpiece. The guide sleeve is close to the end face of the workpiece, and chips are not easily squeezed during processing. Workpieces with similar outer diameters can use the same top plate, instead of using a different top plate for each workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] See also Figure 1-6 The utility model provides the following technical solutions: a fixture for a deep hole drilling machine, comprising a sleeve 3, a bolt flange 2 is fixedly installed on the outer side of the sleeve 3, a sliding sleeve 5 is sleeved inside the sleeve 3, an elastic retaining ring 9 for a hole is also fixedly installed on the end of the sliding sleeve 5 away from the bolt flange 2, a spring 1 is also fixedly installed between the sleeve 3 and the sliding sleeve 5, a guide sleeve 6 is also sleeved on the outer side of the sliding sleeve 5, and a top plate 8 is fixedly installed on the end of the sleeve 3 away from the bolt flange 2.

[0021] In this embodiment, the connection between the sleeve 3 and the bolt flange 2 is welded, and its main function is to fix the entire clamp. The sliding sleeve 5 is installed inside the sleeve 3 through the hole using an elastic retaining ring 9 and a spring 1. The sliding sleeve 5 is arranged in a stepped shape, and a guide sleeve 6 is installed at the wider part of the step.
