Description

Technical Field

[0001] The utility model relates to the technical field of flange processing, in particular to a rotary flange chuck. Background Art

[0002] During the flange processing, the flange needs to be clamped by a fixture to calibrate and fix the flange position to ensure accuracy in subsequent processing.

[0003] Today's flange clamps mostly use symmetrically arranged arc plates to complete clamping by means of interference with the inside and outside of the flange. However, due to precision requirements, some flanges need to be processed on both the inside and outside during the processing process. Since the flange is fixed with the clamp, this type of clamp needs to be frequently re-clamped during use to expose the processed surface, making the operation very cumbersome and inconvenient, and therefore needs to be improved. Utility Model Content

[0013] As a further improvement of the present invention, a handle is provided at the end of the bidirectional screw.

[0014] Beneficial effects of the utility model:

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments, wherein the same components are denoted by the same reference numerals.

[0022] like Figure 1-3 As shown, a rotary flange chuck includes a clamping base 1, on which arc-shaped clamping plates 2 are symmetrically provided. One side of the arc-shaped clamping plates 2 forms a clamping surface 3, on which a plurality of rolling units 4 are arranged. The clamping surface 3 contacts the flange through the rolling units 4, and the rolling units 4 roll along the surface of the flange to rotate the flange relative to the arc-shaped clamping plates 2.

[0023] Preferably, a driving unit 5 is further included, which is connected to the two arc-shaped clamping plates 2 and is used to drive the two arc-shaped clamping plates 2 to move closer to or away from each other.

[0024] When in use, the flange is placed on the clamping seat 1, and the two arc-shaped clamping plates 2 are further driven to move closer to or away from each other through the driving unit 5, so that the two clamping surfaces 3 respectively clamp the two sides of the flange to complete the fixation of the flange position, and then the operator processes the flange. At the same time, during the processing, the flange can be rotated to expose the processing surfaces in different positions. This method can facilitate the operator to process it, and there is no need to worry about the trouble of re-clamping the flange. At the same time, the rolling method can also avoid wear on the flange surface during rotation to ensure the processing quality of the flange.

[0025] Preferably, a mounting groove 6 is provided on the clamping surface 3 , and the rolling unit 4 is partially accommodated in the mounting groove 6 and rotatably connected to the mounting groove 6 via bolts.

[0026] The arrangement of the mounting groove 6 can facilitate the positioning and installation of the rolling unit 4 . At the same time, the mounting groove 6 can shield most of the rolling unit 4 , thereby making the overall volume smaller and the structure more compact.

[0027] Preferably, a gap 7 is formed between the rolling unit 4 and the mounting groove 6 , and a blowing hole 8 is provided at the upper end of the arc-shaped clamping plate 2 corresponding to the gap 7 .

[0028] During use, a high-speed blower can be connected to the blowing port to clean the iron chips in the mounting groove 6 to prevent excessive iron chips from accumulating in the mounting groove 6 and causing poor rotation of the rolling unit 4 and additional wear on the workpiece.

[0029] Preferably, clamping surfaces 3 are formed on both the inner and outer sides of the arc-shaped clamping plate 2 .

[0030] The clamping surfaces 3 provided on the inner and outer sides can act on the inner and outer rings of the flange, and can be clamped by the inner ring of the flange or by the outer ring of the flange, thereby increasing the scope of use.

[0031] Preferably, the rolling unit 4 includes an outer roller 9 , a bearing 10 and a mounting rod 11 . The outer roller 9 is sleeved outside the bearing 10 , and the mounting rod 11 passes through the bearing 10 and is fixed to the bearing 10 .

[0032] The provision of the bearing 10 can greatly improve the smoothness of the rolling of the outer roller 9 and can also reduce the replacement cost when the outer roller 9 is worn.

[0033] Preferably, a sliding groove 12 is provided on the clamping seat 1, and a limiting portion 13 is provided at the lower end of the arc-shaped clamping plate 2 corresponding to the sliding groove 12. The limiting portion 13 is used to limit the sliding of the arc-shaped clamping plate 2 relative to the sliding groove 12. The driving unit 5 includes a bidirectional screw 14. The bidirectional screw 14 is set corresponding to the sliding groove 12 and is rotatably connected to the clamping seat 1. The different thread segments corresponding to the bidirectional screw 14 are not respectively connected to the two arc-shaped clamping plates 2.

[0034] The two arc-shaped clamping plates 2 can be quickly adjusted by driving the bidirectional screw 14 for easy use.

[0035] Preferably, a handle 15 is provided at the end of the bidirectional screw 14 , and the provision of the handle 15 makes it convenient for an operator to apply force to rotate the bidirectional screw 14 .
