Clamping tool for spray pipe machining

Abstract

The utility model relates to the technical field of spray pipe machining, and discloses a clamping tool for spray pipe machining, which comprises a fixed seat, a limiting sliding groove is arranged on the fixed seat, a two-way screw is arranged in the limiting sliding groove, a motor is arranged on one side of the fixed seat, a sliding block is sleeved on the two-way screw, a support ring is arranged on the front side of the sliding block, and the two-way screw is sleeved on the support ring. An annular clamping groove is formed in the inner side of the supporting ring, and a movable ring is rotationally clamped in the annular clamping groove. Due to the fact that the movable ring is rotationally connected with the supporting ring in a clamped mode, the movable ring can be driven to rotate by shifting a hydraulic rod, the machining angle of the spray pipe is rotationally adjusted, then a pressing rod is pressed downwards to make the end, with the long inner diameter, of an elliptic cylinder make extrusion contact with one side of the movable ring, and the elliptic cylinder conducts extrusion positioning on the movable ring; the spraying pipe is prevented from rotating when being machined, and when the angle of the spraying pipe is adjusted, the pressing rod is lifted up, so that the end, with the long inner diameter, of the elliptic cylinder is far away from the movable ring to be extruded, and therefore the movable ring can recover to rotate.

Technical Field

[0001] The utility model relates to the technical field of nozzle processing, in particular to a clamping tool for nozzle processing. Background Technique

[0002] A nozzle refers to a device that accelerates the airflow by changing the geometric shape of the inner wall of the pipe section. Any pipe used to reduce the pressure and increase the speed of the airflow is called a nozzle.

[0003] There are more and more types of nozzles, and the role of nozzles is also getting greater and greater. The demand for nozzles in related industries is increasing year by year. Therefore, for professional nozzle production enterprises, improving the production efficiency and output of nozzles is one of the necessary means to solve the large demand for nozzles. However, in the process of nozzle processing, the nozzle fixture is an important factor affecting the production efficiency and output of nozzles.

[0004] The common clamping tools in the prior art cannot adjust the angle of rotation after clamping the nozzle. Therefore, when drilling the nozzle, it is necessary to clamp the nozzle parts multiple times according to the position of the hole, which is very inconvenient for the drilling process and affects the processing efficiency of the nozzle. Therefore, the technical personnel in this field provide a clamping tool for nozzle processing to solve the problems raised in the above background technique. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a clamping tool for nozzle processing to solve the problem that the nozzle needs to be clamped multiple times according to the position of the hole during the drilling process, and the drilling process is cumbersome and inconvenient, which affects the processing efficiency of the nozzle.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A clamping tool for nozzle processing, including a fixed seat, a limiting sliding groove is opened on the fixed seat, a bidirectional screw is arranged in the limiting sliding groove, a motor is installed on one side of the fixed seat, a sliding block is sleeved on the bidirectional screw, a support ring is installed on the front side of the sliding block, an annular clamping groove is opened on the inner side of the support ring, a movable ring is rotationally clamped in the annular clamping groove, a hydraulic rod is installed on the movable ring, an extrusion plate is installed at the output end of the hydraulic rod, a movable groove is opened on one side of the support ring, an elliptical cylinder is rotatably connected in the movable groove, and a pressing rod is installed on one side of the elliptical cylinder.

[0007] Preferably, the sliding block is slidably clamped with the limiting sliding groove, a threaded hole is opened on the sliding block, and the bidirectional screw is threadedly sleeved with the sliding block through the threaded hole. The bidirectional screw is driven by the motor to rotate, driving the sliding block to move, so as to achieve the purpose of adjusting the support ring, so that the device can be adjusted according to the length of the nozzle, thus being applicable to nozzles of various lengths.

[0008] Preferably, one side of the movable groove is connected to the annular groove, one end of the elliptical cylinder is in compression contact with the movable ring, and the pressure rod is pressed downward so that one end of the long inner diameter of the elliptical cylinder is in compression contact with one side of the movable ring, so that the elliptical cylinder extrude and position the movable ring to avoid rotation of the nozzle when the nozzle is processed, and when adjusting the angle of the nozzle, the pressure rod is lifted so that one end of the long inner diameter of the elliptical cylinder is extruded away from the movable ring, so that the movable ring can resume rotation.

[0009] Preferably, a pointer is installed on one side of the movable ring, and scale lines are engraved on the outer wall of the support ring. When the movable ring is rotated, the rotation angle can be accurately adjusted according to the pointer and the scale on the outer wall of the support ring, thereby rotating and adjusting the angle of the nozzle processing.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] Through the design, after the nozzle is inserted into the support ring and the movable ring, the hydraulic rod drives the extrusion plate to clamp and position the nozzle. Since the movable ring is rotatably connected with the support ring, the movable ring can be driven to rotate by toggling the hydraulic rod. During rotation, the rotation angle can be accurately adjusted according to the pointer and the scale on the outer wall of the support ring, thereby rotating and adjusting the angle of the nozzle processing. Subsequently, the pressure rod is pressed down so that one end of the long inner diameter of the elliptical cylinder is in contact with one side of the movable ring, so that the elliptical cylinder extrude and position the movable ring, thereby avoiding rotation of the nozzle when processing the nozzle. When adjusting the angle of the nozzle, the pressure rod is lifted so that one end of the long inner diameter of the elliptical cylinder is away from being squeezed with the movable ring, thereby allowing the movable ring to resume rotation. This structure does not require multiple clamping of the nozzle, thereby solving the problem of nozzle processing efficiency being affected. BRIEF DESCRIPTION OF THE DRAWINGS
