Description
Technical Field
The utility model relates to a screwed joint pressure sensor's diaphragm welding frock belongs to sensor diaphragm welding technical field.
Background
To screwed joint pressure sensor's diaphragm laser welding, current welding frock when welding diaphragm and the clamping ring to the sensor, confirm concentricity and laminating degree through the manual work, the operation is inconvenient, and welding efficiency is low, and diaphragm, clamping ring and sensor joint concentricity appears easily poorly, and the condition of clamping ring, diaphragm off normal position appears after the welding, and the diaphragm compresses tightly the effect poorly, and the condition that the diaphragm was penetrated to laser can appear after the welding, and welding quality is poor, and the yields is low.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a screwed joint pressure sensor's diaphragm welding frock, technical scheme is:
the utility model provides a screwed joint pressure sensor's diaphragm welding frock which characterized in that: the sleeve is characterized by comprising a sleeve, wherein an opening structure in the sleeve is in a boss shape, a fixing rod corresponding to the opening structure is arranged in the sleeve, the top end of the fixing rod extends to the outside of the sleeve, an annular groove is formed in the upper part of the fixing rod, and an O-shaped ring is sleeved in the annular groove; the bottom of the sleeve is in threaded connection with the sensor, a pressing ring and a diaphragm are arranged between the sensor and the fixed rod, the pressing ring is arranged above the diaphragm, and the bottom of the sensor is installed in the lower tool.
Preferably, the bottom of the sensor is hexagonal prism shaped.
Further, the lower tool comprises a first cylinder and a second cylinder, a hexagonal groove corresponding to the shape of the bottom of the sensor is formed in the first cylinder, and the second cylinder is fixedly connected to the middle of the bottom end of the first cylinder.
The utility model has the advantages that:
1. the concentricity of the sensor, the diaphragm and the compression ring is ensured simultaneously through the matching relationship of the fixed rod and the sleeve and the matching relationship of the sensor and the sleeve, so that the product problem caused by poor concentricity is avoided;
2. the fit degree of the sensor, the diaphragm and the compression ring is ensured simultaneously through the threaded fit of the sensor and the sleeve and the compression of the fixed rod, so that the product problem caused by poor fit is avoided;
3. when the pressure ring and the diaphragm are released, the sleeve is limited by the O-shaped ring to ensure the installation of the pressure ring and the diaphragm; before welding, the sleeve pipe is screwed up to be sleeved on the O-shaped ring, and the sleeve pipe is fixed through the O-shaped ring, so that the operation is convenient, and the positioning effect is good.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-3, a diaphragm welding tool for a screwed joint pressure sensor is characterized in that: the sleeve comprises a sleeve 1, wherein an opening structure in the sleeve 1 is in a boss shape, a fixing rod 2 corresponding to the opening structure is arranged in the sleeve 1, the top end of the fixing rod 2 extends to the outside of the sleeve 1, an annular groove is formed in the upper part of the fixing rod 2, and an O-shaped ring 3 is sleeved in the annular groove; the bottom threaded connection sensor 4 of sleeve pipe 1, be equipped with clamping ring 5 and diaphragm 6 between sensor 4 and the dead lever 2, clamping ring 5 is located diaphragm 6 top and sets up, install in frock 7 down in the bottom of sensor 4.
The bottom of the sensor 4 is in a hexagonal prism shape, the lower tool 7 comprises a first cylinder 701 and a second cylinder 702, a hexagonal groove corresponding to the bottom of the sensor 4 in shape is formed in the first cylinder 701, the second cylinder 702 is installed on a three-jaw chuck of laser welding equipment, the bottom of the sensor 4 is installed in the hexagonal groove, and the second cylinder 702 is concentric with the first cylinder 701.
The utility model discloses a use method does: install dead lever 2 at the sleeve pipe 1 at first, make O type circle 3 be in downside position, hand rest dead lever 2, it is spacing to sleeve pipe 1 through O type circle 3, prevent the landing, cause dead lever 2 to stretch out sleeve pipe 1, then place clamping ring 5 and diaphragm 6 in proper order at the intraductal, again with the screwed joint threaded connection on sensor 4 on sleeve pipe 1, then invert sleeve pipe 1 and sensor 4 as whole, install sensor 4 bottom in the hexagonal groove of frock 7 down, fix on the second cylinder 702 of frock 7 down through the laser-beam welding machine three-jaw head, and compress tightly dead lever 2 with the pressure head on the welding machine. During welding, the sleeve 1 is rotated to be separated from the sensor 4, the O-shaped ring 3 is located in the sleeve 1 and moves upwards, the sleeve 1 is locked in position through the O-shaped ring 3, and the pressing ring 5 and the diaphragm 6 are exposed outside to be welded. When installation clamping ring 5 and diaphragm 6, O type circle 3 is spacing to sleeve pipe 1, and 3 fixed sleeving 1 of O type circle prevent the landing before the welding, and O type circle 3's use is more ingenious, easy operation, and the effect is obvious.
The utility model discloses the concentricity and the laminating degree of sensor 4, diaphragm 6, clamping ring 5 when having guaranteed the welding of pressure sensor diaphragm promote welding quality and welding efficiency.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
