Description

Technical Field

[0001] The utility model relates to the technical field of assembly equipment, in particular to a mounting structure of a pressure sensor. Background Art

[0002] In common press machines, pressure sensors are installed vertically. The main body of the pressure sensor is fixed to the electric cylinder push rod, and the collection end of the pressure sensor is connected to the pressure head. During each press, the cable of the sensor will reciprocate up and down with the electric cylinder push rod, which can easily cause the cable to break and cause the sensor to fail. In addition, due to the deadweight of the pressure head, the sensor is always subjected to a negative pressure value. Although it can be solved in a short time by calculation compensation, as the number of presses increases, the sensor has a zero drift problem, resulting in inaccurate sensor detection. Therefore, it is necessary to improve the above problems. Summary of the invention

[0003] The utility model aims at the defects of the pressure sensor cable in the prior art such as easy damage and easy zero drift, and provides a new installation structure of the pressure sensor.

[0004] In order to solve the above technical problems, the utility model is implemented through the following technical solutions:

[0005] A pressure sensor installation structure includes a pressure sensor, a fixing plate, and a jig connecting plate. The pressure sensor is fixed to the side of the fixing plate. The jig connecting plate is fixedly connected to the collecting end of the pressure sensor. The jig connecting plate, the pressure sensor, and the fixing plate form a horizontal press-fitted sensing structure.

[0006] The pressure sensor is fixed to the side of the fixed plate to achieve horizontal lateral collection. The pressure sensor is fixed and the sensor cable will not move back and forth with the press-fitting action to avoid movement damage. The fixture connection plate is fixedly connected to the collection end of the pressure sensor to achieve horizontal lateral press-fitting. Horizontal lateral collection and horizontal lateral press-fitting together form a horizontal press-fitting sensing structure. The pressure sensor has no relative force in the lateral direction, no zero drift in the static state, and will not affect the lateral detection accuracy.

[0007] The utility model solves the problems of easy zero drift of the pressure sensor and easy damage of the sensor cable through the above-mentioned design, and improves the detection accuracy and service life of the pressure sensor.

[0008] Preferably, the above-mentioned pressure sensor installation structure further includes a floating plate and a guide column, the floating plate is slidably connected to the guide column, the guide column is fixed to the side of the fixed plate, and the fixture connecting plate is fixed to the floating plate.

[0009] The floating plate is used for sliding. During press-fitting, the jig connecting plate is subjected to force, which is transmitted to the pressure sensor to generate pressure data. The floating plate slides along the jig connecting plate through the guide column, which will not affect the lateral press-fitting pressure, thereby ensuring the detection accuracy.

[0010] Preferably, the above-mentioned installation structure of a pressure sensor further includes a floating plate fixing screw, and the fixture connecting plate and the collection end of the pressure sensor are fixedly connected by the floating plate fixing screw.

[0011] The floating plate fixing screws play a role of fixing the connection and improve the structural strength.

[0012] Preferably, in the above-mentioned installation structure of a pressure sensor, the number of the guide pillars is 4, and the guide pillars are distributed in parallel at the four corner areas of the fixing plate.

[0013] There are 4 guide posts, which takes into account both cost and structural strength. The parallel distribution ensures the guiding effect. The four corner areas refer to the four corner edge areas of the rectangular four corners of the fixed plate. The guide posts are distributed in the four corner areas, freeing up a larger internal space, which is more conducive to the setting of other press-fitted components.

[0014] Preferably, the above-mentioned installation structure of a pressure sensor further comprises a linear bearing, wherein the linear bearing is fixed to the floating plate and the linear bearing is slidably connected to the guide column.

[0015] Linear bearings are used for the sliding of the floating plate, which improves the sliding smoothness and thus ensures the detection accuracy of the pressure sensor.

[0016] Preferably, the above-mentioned pressure sensor installation structure further comprises a sensor cable, and the sensor cable is located between the floating plate and the fixed plate.

[0017] The sensor cable is located between the floating plate and the fixed plate and will not move back and forth or touch other components, thus avoiding damage and increasing the service life of the pressure sensor. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following is combined with Figure 1-3The present invention is further described in detail with the following specific embodiments, but they are not intended to limit the present invention:

[0022] Example 1

[0023] A pressure sensor installation structure includes a pressure sensor 1, a fixing plate 2, and a jig connecting plate 3. The pressure sensor 1 is fixed to the side of the fixing plate 2. The jig connecting plate 3 is fixedly connected to the collection end of the pressure sensor 1. The jig connecting plate 3, the pressure sensor 1, and the fixing plate 2 form a horizontal press-fitted sensing structure.

[0024] Preferably, it further comprises a floating plate 4 and a guide column 5 , wherein the floating plate 4 is slidably connected to the guide column 5 , the guide column 5 is fixed to the side surface of the fixed plate 2 , and the jig connecting plate 3 is fixed to the floating plate 4 .

[0025] Preferably, it further comprises a floating plate fixing screw 6 , and the jig connecting plate 3 and the collecting end of the pressure sensor 1 are fixedly connected via the floating plate fixing screw 6 .

[0026] Preferably, the number of the guide pillars 5 is four, and the guide pillars 5 are distributed in parallel at the four corners of the fixing plate 2 .

[0027] Preferably, a linear bearing 7 is further included, wherein the linear bearing 7 is fixed to the floating plate 4 , and the linear bearing 7 is slidably connected to the guide column 5 .

[0028] Preferably, a sensor cable 8 is further included, and the sensor cable 8 is located between the floating plate 4 and the fixed plate 2 .

[0029] like Figure 3 As shown, during vertical press-fitting, the electric cylinder push rod 101 pushes the pressure head 103 for press-fitting, and the existing sensor 102 detects the pressure on the pressure head 103. The existing cable 100 will move up and down with the existing sensor 102, which is very easy to cause damage. When not press-fitting, the existing sensor 102 is affected by gravity and is prone to zero drift.

[0030] like Figure 1-2 As shown, during horizontal press-fitting, the jig connecting plate 3 is stressed, and the floating plate 4 slides following the jig connecting plate 3, so that the pressure sensor 1 obtains an accurate pressure value. The pressure sensor 1 has no relative force in the lateral direction, the pressure value is more accurate, and zero drift will not occur.

[0031] In short, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made within the scope of the patent application for the present invention should fall within the scope of the present invention.
