Problems solved by technology

[0002] During the workpiece cutting process, due to the gravity of the cylinder, machining vibration, workpiece movement, temperature rise, etc., the clamped part of the cylinder is prone to deformation, which leads to a decrease in the clamping force between the friction block and the cylinder, and the cylinder The body is easy to break away from the grip of the fixture, and the cylinder is loose, resulting in poor machining accuracy or safety accidents

Embodiment 1

[0025] Such as figure 1 , 2 As shown, an internally tensioned hollow cylinder fixture with rollers includes: a main shaft 1, a fastener 2, and a looper 3. The looper is provided with an internal thread and is socketed on one side of the main shaft;

[0026] The main shaft 1 is provided with an external thread 101 that matches the internal thread of the looper, and a fixed plate 102 is vertically provided on the main shaft 1 relative to the end of the looper 3;

[0027] The fastener 2 includes a connecting rod, a rotating shaft 203 and a fastening roller 206. The connecting rod includes a first connecting rod 201 and a second connecting rod 202. One end of the first connecting rod 201 is connected to the rotating shaft and the other end is connected to the hinged shaft. The looper 3 is connected to the hinged shaft; one end of the second connecting rod 202 is connected to the hinged shaft of the rotating shaft, and the other end is connected to the fixed disk 102 hinged shaft....

Embodiment 2

[0037] When the main shaft 1 rotates in the clockwise direction, the looper approaches the fixed disk 102 along the thread, the fastening roller 206 lifts up, and the workpiece is clamped; when the main shaft 1 rotates in the counterclockwise direction, the looper moves away from the fixed plate 102 along the thread. The disc 102, the fastening roller 206 descends, and the workpiece is loosened.

[0038] During the workpiece cutting process, due to the weight of the cylinder body, machining vibration, workpiece movement, temperature rise, etc., the clamped part of the cylinder body is loose or deformed. At this time, the fastening roller 206 is provided by the sulfur-free hard rubber layer 204 Rotating with the workpiece under the friction force, the tension of the inner tension hollow cylinder fixture increases, and the friction force on the inner wall of the workpiece increases to prevent the workpiece from loosening.

Abstract

The invention relates to an internal-expanding hollow cylinder clamp with a rolling wheel. The internal-expanding hollow cylinder clamp comprises a main shaft, fastening pieces and a movable sleeve, wherein an inner internal thread is formed in the movable sleeve, and the movable sleeve sleeves one side of the main shaft; an external thread matched with the internal thread of the movable sleeve isformed in the whole main shaft, and a fixing disc is perpendicularly arranged at the end, relative to the movable sleeve, on the main shaft; the fastening pieces comprise connecting rods, rotating shafts and fastening rollers, the connecting rods comprise first connecting rods and second connecting rods, the first connecting rods are hinged to the rotating shafts, and the second connecting rods are hinged to the rotating shafts; cross sections of the fastening rollers are gradually-open circular, and the fastening rollers positively rotate or negatively rotate around the rotating shafts, andare connected with the rotating shafts through torsion springs. According to the internal-expanding hollow cylinder clamp with the rolling wheel, clamping is stable and powerful and convenient to loosen, and the internal-expanding hollow cylinder clamp can adapt to small deformations in the processing process of workpieces, and has the good clamping effect on hollow cylinders or pipes with different sizes and different shapes.

Description

technical field [0001] The invention belongs to the field of metal cutting processing fixtures, and in particular relates to an internally tensioned hollow cylinder fixture with rollers. Background technique [0002] During the workpiece cutting process, due to the gravity of the cylinder, machining vibration, workpiece movement, temperature rise, etc., the clamped part of the cylinder is prone to deformation, which leads to a decrease in the clamping force between the friction block and the cylinder, and the cylinder The body is easy to break away from the grip of the fixture, and the cylinder body is loose, resulting in poor machining accuracy or safety accidents. Contents of the invention [0003] The object of the present invention is to provide an internal tension type hollow cylinder clamp with rollers which can stably clamp workpieces. [0004] Another object of the present invention is to provide an internally tensioned hollow cylinder clamp with rollers that can ...
