Description

Technical Field

[0001] The utility model relates to a tool guide sleeve device with an automatic phase alignment function, belonging to the technical field of tool guide sleeves. Background Art

[0002] The tool guide sleeve is used to accurately position the tool on the workpiece to ensure machining accuracy and quality. Before the tool and guide sleeve are assembled, the two must be adjusted to be consistent in phase so that the key of the tool can smoothly enter the keyway of the guide sleeve. The existing guide sleeve requires an additional hydraulic locking device to ensure that the phase of the guide sleeve is consistent with the tool when aligning with the tool. The structure is redundant and complex, the cost is high, and it occupies a large space. Utility Model Content

[0003] In order to solve the defects existing in the prior art, the purpose of the utility model is to provide a tool guide sleeve device with a phase automatic alignment function which has a simplified structure and reduces space occupation.

[0004] The technical solution of the utility model is: a tool guide sleeve device with an automatic phase alignment function, a base is provided at the bottom of the shell, the guide sleeve is rotatably connected to the shell and the base on the outer periphery through a bearing, a guide thread groove is provided at the knife inlet of the guide sleeve, the guide thread groove is connected to the key groove, end covers a and end covers b are provided at both ends of the shell, and the top of the base is located between the end covers a and the end covers b.

[0005] A sealing cover is provided between the end cover a and the guide sleeve, and a ring groove for fixing a sealing ring is opened on the sealing cover, and the sealing cover and the guide sleeve are sealed by the sealing ring.

[0006] The bearing comprises a bearing a and a bearing b located at two ends of the guide sleeve.

[0007] A spacer sleeve a and a spacer sleeve b are provided between the bearing a and the bearing b. The spacer sleeve a is sleeved on the guide sleeve, and the spacer sleeve b is sleeved on the spacer sleeve a. The two ends of the spacer sleeve a connect the inner rings of the bearing a and the bearing b, and the two ends of the spacer sleeve b connect the outer rings of the bearing a and the bearing b. A gap is provided between the spacer sleeve a and the spacer sleeve b.

[0008] The beneficial effects of the utility model are: no need to use a hydraulic locking device, simplified structure, reduced space occupation, and canceled additional hydraulic actions, greatly saving equipment beats and costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural diagram of the utility model;

[0010] Figure 2 It is a cross-sectional view of the utility model;

[0011] Figure 3 This is the structural diagram of the guide sleeve.

[0012] The reference numerals in the figure are as follows: 1. guide sleeve, 2.1. bearing a, 2.2. bearing b, 3. housing, 4. guide thread groove, 5. keyway, 6.1. spacer sleeve a, 6.2. spacer sleeve b, 7. base, 8. end cover a, 9. end cover b, 10. sealing cover, 11. sealing ring. DETAILED DESCRIPTION

[0013] The following is combined with Figure 1-3 The utility model is further described as follows:

[0014] A tool guide sleeve device with an automatic phase alignment function, a base 7 is provided at the bottom of a shell 3, a guide sleeve 1 is rotatably connected to the shell 3 on the outer periphery and the base 7 at the bottom through bearings a2.1 and bearings b2.2 at both ends, a guide thread groove 4 is provided at the knife entry of the guide sleeve 1, the guide thread groove 4 is connected to a key groove 5, end covers a8 and end covers b9 are fixed at both ends of the shell 3, and the top of the base 7 is located between the end covers a8 and b9. A spacer sleeve a6.1 and a spacer sleeve b6.2 are provided between the bearing a2.1 and the bearing b2.2. The spacer sleeve a6.1 is sleeved on the guide sleeve 1, and the spacer sleeve b6.2 is sleeved on the spacer sleeve a6.1. The two ends of the spacer sleeve a6.1 are connected to the inner rings of the bearing a2.1 and the bearing b2.2. The spacer sleeve a6.1 rotates synchronously with the inner ring of the bearing and the guide sleeve 1. The two ends of the spacer sleeve b6.2 are connected to the outer rings of the bearing a2.1 and the bearing b2.2. The spacer sleeve a6.1 does not rotate. A gap is provided between the spacer sleeve a6.1 and the spacer sleeve b6.2 to avoid wear caused by rotation. When the tool is fed, the key on the tool moves along the guide thread groove 4 and enters the key groove 5. When the key and the guide thread groove 4 move relative to each other, the key acts on the inner wall of the guide thread groove 4, and the force drives the guide sleeve 1 to rotate until the key faces the key groove and enters the key groove, thereby realizing automatic alignment of the tool and the guide sleeve.

[0015] A sealing cover 10 is provided between the end cover a8 and the guide sleeve 1 . A groove for fixing a sealing ring 11 is provided on the sealing cover 10 . The sealing cover 10 and the guide sleeve 1 are sealed by the sealing ring 11 .
