Description

Technical Field

[0001] The utility model relates to the technical field of exhaust valve processing, and particularly relates to a positioning fixture for exhaust valve processing. Background Art

[0002] The processing of exhaust valves refers to the process of manufacturing exhaust valves through a series of machining processes. An exhaust valve is a valve used to exhaust gas and prevent liquid backflow, and is widely used in fields such as steam boilers, pressure vessels, and pipeline systems.

[0003] After retrieval, the applicant found that the Chinese patent disclosed "a drying device for the production and processing of exhaust valves", and its publication (announcement) number is "CN212902424U". This patent mainly sets a turntable in cooperation with a driving ring. When in use, the operator aligns the exhaust valve and sleeved it into the mounting sleeve, and the driving motor system operates to drive the coaxial rotation of the rotating shaft. The turntable rotates accordingly. Since the connecting gear meshes with the driving tooth ring, the connecting gear generates self-rotation during the rotation with the disc, driving the rotating shaft to rotate. At the same time, the exhaust valve on the mounting sleeve rotates, realizing the structure that multiple exhaust valves rotate around the rotating shaft as the center and revolve around the coaxial position as the center. While ensuring the simultaneous drying of multiple exhaust valves to improve efficiency, it ensures uniform heating of the exhaust valves to guarantee the drying effect, effectively enhancing the practicability of the device. However, during the processing of traditional exhaust valves, it requires manual handling by workers, increasing the workload and working difficulty of the workers. Moreover, during the processing of traditional exhaust valves, there is no positioning fixture, resulting in the inability to firmly fix the workpiece during the processing of the exhaust valve, and the workpiece may shift during use, reducing the processing efficiency of the exhaust valve and increasing the safety hazards during the processing of the exhaust valve. At this time, a positioning fixture for exhaust valve processing is needed to solve the above problems. Summary of the Utility Model

Subsequently, the first motor 6 is started to drive the threaded rod 7 to rotate, thereby driving the first threaded block 8 and the connected device to move up and down, ensuring the positioning effect of the device in the up and down positions. Subsequently, the second motor 13 is started, and the second motor 13 drives the first bevel gear 14 to rotate, thereby driving the second bevel gear 15 to rotate, and further driving the bidirectional lead screw 16 to rotate. The bidirectional lead screw 16 drives the two second threaded blocks 17 and the two clamping blocks 18 connected thereto to move relatively or in the opposite direction, thereby realizing the clamping and releasing effects of the device on the exhaust valve, ensuring the clamping function of the device. By setting a moving mechanism, a lifting mechanism, a clamping mechanism, etc., the device ensures the positioning and clamping functions, avoids the problem that traditional exhaust valves need to be manually moved by workers during processing, reduces the workload of workers, reduces the working difficulty of workers, and also avoids the problem that traditional exhaust valve processing has no positioning fixture, resulting in the workpiece not being firmly fixed during processing and the workpiece may shift during use. It improves the processing efficiency of the exhaust valve, reduces the safety hazards during exhaust valve processing, and ensures the use effect of the device;
