Description

Technical Field

[0001] The present application relates to the technical field of pump assembly assembly, and in particular to a displacement sensor lifting and adjusting device. Background Art

[0002] During pump assembly, the pressure column on the workbench corresponds to the mounting seat. A support plate is fixed to the mounting seat, which has a sliding pressure seat. The pressure column presses down, causing the pressure seat to move downward, pressing the parts held under the pressure seat into the pump assembly. However, the pressure column's downward stroke is uncertain, making it difficult to accurately press the assembled parts into the pump assembly from the right side.

[0003] With respect to the above-mentioned related technologies, the inventor believes that during the assembly process of the pump assembly, the downward stroke of the pressure column cannot be determined, so that the assembly parts cannot be accurately pressed into the pump assembly. Utility Model Content

[0004] The purpose of this application is to provide a displacement sensor lifting and adjusting device, which can determine the stroke of the pressure column through the displacement sensor, thereby improving the problem that the assembly parts cannot be accurately pressed into the pump assembly due to the inability to determine the downward stroke of the pressure column.

[0005] The present application provides a displacement sensor lifting and adjusting device that adopts the following technical solution:

[0006] A displacement sensor lifting and adjusting device includes a workbench, a pressure column is provided on the workbench, a mounting seat corresponding to the pressure column is provided below the pressure column, and a pressure seat connected by a support plate is provided on the mounting seat. The device is characterized in that a fixedly connected displacement sensor is provided on one side of the pressure column, a probe is connected to the displacement sensor, and the probe corresponds to the mounting seat.

[0007] By adopting the above technical solution, the displacement sensor is installed on the pressure column. The downward pressure of the pressure column drives the displacement sensor downward, so that the probe of the displacement sensor contacts the mounting seat, thereby measuring the stroke of the pressure column, so that the pressure column can accurately press the assembly parts into the pump assembly.

[0008] Optionally, a through hole is provided on the pressure seat, and the through hole is coaxially arranged with respect to a probe of the displacement sensor.

[0009] By adopting the above technical solution, when the pressure column is pressed down, the probe of the displacement sensor can directly pass through the pressure seat and contact the mounting seat through the through hole on the pressure seat, thereby avoiding contact between the probe of the displacement sensor and the pressure seat, causing the displacement sensor to measure the wrong stroke of the pressure column and making it impossible for the assembly parts to be pressed into the pump assembly normally.

[0010] Optionally, the mounting seat is provided with an upwardly extending extension plate, a protrusion is fixedly connected to the extension plate, and the protrusion is coaxially arranged relative to the probe of the displacement sensor.

[0011] By adopting the above technical solution, by fixing the protrusion connected to the extension plate, the displacement sensor probe is prevented from causing errors in the stroke measurement of the pressure column due to length problems, so that the displacement sensor probe can contact the protrusion faster, the stroke of the pressure column can be measured faster, and the accuracy of pressing the assembled parts into the pump assembly is improved.

[0012] Optionally, a planar groove is provided on the pressure column, a fixedly connected bracket is provided on the planar groove, a fixing hole for fixing the displacement sensor is opened on the bracket, and the fixing hole corresponds to the through hole on the pressure seat.

[0013] By adopting the above technical solution, the displacement sensor is fixed to the bracket through the fixing hole, which reduces the shaking of the displacement sensor when the pressure column is pressed down, thereby reducing the impact on the measurement of the pressure column stroke.

[0014] Optionally, an elastic member is provided at the probe position of the displacement sensor, one end of the elastic member is connected to the probe of the displacement sensor, and the other end is connected to the interface between the displacement sensor and the probe.

[0015] By adopting the above technical solution, when the pressure column presses down, the probe of the displacement sensor will contact the protrusion on the extension plate. After the pressure column continues to press down, the probe will retract into the displacement sensor, the elastic part will contract, and the stroke of the pressure column will begin to be measured. After the pressure column moves up, the displacement sensor will also rise, the elastic part will recover, and the probe of the displacement sensor will pop out, so that the probe of the displacement sensor can return to its original state after the stroke measurement of the pressure column is completed.

[0016] Optionally, a positioning pin is inserted into one side of the displacement sensor of the bracket, and the positioning pin passes through a pin hole of the displacement sensor and is connected to the bracket.

[0017] By adopting the above technical solution, the displacement sensor is fixed with a fixing pin to prevent the displacement sensor from detaching from the fixing hole on the bracket, reducing the vibration of the displacement sensor and making the measurement of the pressure column stroke more accurate.

[0018] Optionally, a clamping piece is provided at the connection between the fixing hole and the displacement sensor, and the inner surface of the clamping piece matches the connection of the probe of the displacement sensor.

[0019] By adopting the above technical solution, the probe connection of the displacement sensor is connected with a clamping piece, and then the clamping piece is installed in the fixing hole. The clamping piece contracts to fix the displacement sensor, thereby reducing the shaking of the displacement sensor.

[0020] Optionally, a fixing piece is provided on the clamping piece, and the fixing piece is fixedly connected to the outer surface of the clamping piece.

[0021] By adopting the above technical solution, after the clamping piece is installed into the fixing hole, the clamping piece is fixed with a fixing piece to prevent the clamping piece from detaching from the fixing hole, thereby reducing the shaking of the displacement sensor on the bracket. After the fixing piece is removed, the clamping piece can be removed from the mounting hole of the bracket, and the displacement sensor can be removed from the bracket, making the installation and removal of the displacement sensor convenient and quick.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. A displacement sensor is provided on one side of the pressure column. The pressure column is pressed down and raised to move the displacement sensor up and down, so that the probe of the displacement sensor contacts the mounting seat, and the stroke of the pressure column is measured. A through hole corresponding to the probe of the displacement sensor is provided on the pressure seat, and an upwardly extending extension plate is provided on the mounting seat. A fixedly connected protrusion is provided on the extension plate. The protrusion corresponds to the through hole of the pressure seat through which the probe of the displacement sensor passes. As the pressure column is pressed down, the displacement sensor can pass through the through hole of the pressure seat and contact the extension piece on the extension plate, so that the displacement sensor can measure the stroke of the pressure column more quickly.

[0024] 2. A flat groove is provided on the pressure column, and a bracket is fixed on the flat groove to prevent the bracket from being unstable. A fixing hole for fixing the displacement sensor is provided on the bracket. An elastic member is provided between the probe of the displacement sensor and the bracket. A pin hole is provided on the displacement sensor. A fixing pin is inserted into the bracket through the pin hole of the displacement sensor to keep the displacement sensor fixed on the bracket, thereby reducing the impact on the measurement of the pressure column stroke.

[0025] 3. Fit the clamping piece to the probe connection of the displacement sensor, then install the clamping piece and the displacement sensor into the fixing hole, shrink the clamping piece to fix the displacement sensor, and then use the fixing piece to fix the lower end of the clamping piece to fit it to the lower surface of the bracket to prevent the displacement sensor from falling off. When the displacement sensor needs to be disassembled, remove the fixing piece from the lower end of the clamping piece, take out the clamping piece together with the displacement sensor, and realize the installation and disassembly of the displacement sensor.

[0033] refer to Figure 2 and Figure 3 , a flat groove 10 is provided on the pressure column 2, which fits with the outer surface of the bracket 11. The bracket 11 is fixed to the pressing side with screws. A fixing hole 13 is provided on the bracket 11. The clamping piece 14 is installed at the place where the displacement sensor 6 is connected to the probe 61. The clamping piece 14 is a clamping clamp. The lower part of the outer surface of the clamping clamp is provided with a thread. The inner surface of the clamping piece 14 fits with the outer surface of the connection. The inner surface of the fixing hole 13 fits with the outer surface of the clamping piece 14. The lower end of the tightening piece 14 is fixed by a fixing piece 15. The fixing piece 15 is a nut, which is threadedly connected to the lower end of the clamping piece 14, so that the displacement sensor 6 is fixed on the bracket 11. The outer surface of the probe 61 of the displacement sensor 6 is provided with an elastic piece 12, which is a spring.

[0034] refer to Figure 1 and Figure 4The displacement sensor 6 is installed on the bracket 11 through the clamping piece 14 and the fixing piece 15.

[0035] The implementation principle of the embodiment of this application is:

[0036] The pressure column 2 on the workbench 1 presses down, and the displacement sensor 6 fixed on the pressure column 2 moves down with the pressure column 2. When the pressure column 2 is pressed down to the pressure seat 5, the probe 61 of the displacement sensor 6 passes through the through hole 7 on the pressure seat 5. The pressure column 2 continues to press down, allowing the pressure seat 5 and the displacement sensor 6 to continue to move down until the probe 61 of the displacement sensor 6 contacts the protrusion 9 of the extension plate 8 fixed to the mounting seat 3. When the pressure column 2 continues to press down, the displacement sensor 6 continues to move down, the probe 61 begins to shrink, the elastic member 12 tightens, and the displacement sensor 6 begins to record the stroke of the pressure column 2. When the pressure column 2 presses the part into the pump assembly, the probe 61 of the displacement sensor 6 shrinks to the minimum, and the displacement sensor 6 records the complete stroke of the pressure column 2 pressing the part into the pump assembly. The pressure column 2 moves up, and the displacement sensor 6 follows it up. The elastic member 12 on the probe 61 begins to reset, and the probe 61 of the displacement sensor 6 extends. When the displacement sensor 6 needs to be replaced, pull out the positioning pin, remove the fixing part 15 outside the clamping part 14 at the connection between the displacement sensor 6 and the probe 61, take the displacement sensor 6 out of the positioning groove, and then remove the clamping part 14 from the displacement sensor 6 so that the displacement sensor 6 can be assembled and unassembled.
