Description

Technical Field

[0001] The utility model relates to the technical field of valve stem processing and positioning, in particular to a turning device suitable for valve stem processing. Background Art

[0002] The valve stem is an important part of the valve, used for transmission, connected to the actuator or handle on the top, and directly drives the valve core to move or rotate below to achieve the valve opening or adjustment function. When processing the valve stem, holes and grooves need to be opened on the outer surface of the stem body.

[0003] A Chinese patent discloses a positioning structure for stainless steel valve stem processing, with the publication number CN213136008U, comprising a support base plate, two support blocks are fixedly connected to the top of the support base plate, a transverse block is fixedly connected between the two support blocks, a servo motor is fixedly connected to the top of the transverse block, the output shaft of the servo motor is fixedly connected to the drill head, and two adjustment blocks are fixedly connected to the top of the support base plate, and adjustment slots are provided on the opposite sides of the two adjustment blocks. The positioning structure for stainless steel valve stem processing effectively achieves the purpose of easy adjustment by replacing manual adjustment clamping with electric adjustment clamping, and by adding structures such as exhaust holes, connecting boxes and exhaust fans, the positioning structure for stainless steel valve stem processing effectively achieves the purpose of dust removal under the exhaust action of the exhaust fan.

[0004] However, the following disadvantages are still included: the device controls the extension of the second telescopic rod to clamp and position the valve stem, but when the valve stem is processed, multiple slots and holes need to be opened around it, and the device removes the valve stem and reinstalls it, which makes it inconvenient to flip the valve stem and adjust the clamping angle of the valve stem. Therefore, we propose a flipping device suitable for valve stem processing to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to provide a turning device suitable for valve stem processing to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solutions: a turning device suitable for valve stem processing, comprising an operating table, a clamping device is arranged above the operating table, and the clamping device comprises a clamping part;

[0007] The clamping part includes a clamping block, a mounting block, a screw, a second bevel gear, a slide plate, and a rotating shaft. The outer surface of the mounting block is provided with a slide groove. The outer surface of the screw is rotatably connected to the inner wall of the slide groove through a first bearing seat. The second bevel gear is fixedly sleeved on the outer surface of the rotating shaft. The outer surface of the clamping block is fixedly connected to the outer surface of the slide plate.

[0009] The rotating part comprises a motor and a worm, the bottom surface of the motor is fixedly connected to the top surface of the operating table, and the front surface of the worm is fixedly connected to the back surface of the motor output rod.

[0010] A further improvement is that the clamping part also includes a first bevel gear, which is fixedly sleeved on the outer surface of the screw, and the outer surface of the right end of the slide plate extends to the inside of the slide groove and is threadedly sleeved on the outer surface of the screw. By arranging the screw, the first bevel gear, the slide plate and the clamping block, the first bevel gear is rotated, the first bevel gear drives the screw to rotate, and the screw drives the slide plate and the clamping block to move together, so that the clamping block clamps the valve stem to clamp and position the valve stem.

[0012] A further improvement is that the rotating part also includes a support plate and a worm gear, an annular groove is opened on the outer surface of the mounting block, the inner wall of the support plate extends into the inside of the annular groove and is slidably connected to the inner wall of the annular groove, and the bottom surface of the support plate is fixedly connected to the top surface of the operating table. By setting the support plate, the mounting block is supported by the support plate and the mounting block can be rotated at the same time, which facilitates changing the installation angle of the valve stem and improves the practicability of the device.

[0013] A further improvement is that the worm gear fixing sleeve is arranged on the outer surface of the mounting block, and the outer surface of the worm gear is meshingly connected with the outer surface of the worm. By setting a motor, a worm and a worm gear, the motor is started to drive the worm to rotate, drive the worm wheel to rotate, the worm gear drives the mounting block and the clamping block to rotate together, and the clamping block drives the valve stem to rotate together. In this way, the angle of the valve stem can be changed without releasing the clamping force on the valve stem, thereby facilitating the rotation processing of the outer surface of the valve stem.

[0014] A further improvement is that a dust box is fixedly connected to the inner wall of the operating table, a through hole is opened on the top surface of the operating table, and a grid plate is fixedly connected to the inner wall of the through hole.
