Description

Technical Field

[0001] This utility model relates to the field of sensor processing technology, and in particular to a press for processing urea sensors. Background Technology

[0002] In automotive aftertreatment systems, the urea sensor is a core component for diesel exhaust denitrification. Its structural precision directly determines the control accuracy of the urea solution injection volume, thus affecting whether exhaust emissions meet standards. A urea sensor is typically assembled from components such as a housing, probe, and seals. During manufacturing, key processes such as seal press-fitting and component riveting are performed using a press. Press-fitting accuracy and pressure control stability are core indicators for ensuring sensor performance.

[0003] Traditional presses for urea sensor processing often use simple clamps for workpiece fixation, lacking precise centering and guiding structures. When the sensor housing is placed on the worktable, it is prone to eccentricity and tilting, resulting in low workpiece positioning accuracy and large pressing deviations. Therefore, it is urgent to design a new type of press for urea sensor processing to solve the above problems. Utility Model Content

When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0014] This utility model provides a press for processing urea sensors, the structure of which is as follows: Figure 1-3 As shown, the machine includes a machine base 1, on which a support base 2 and a pressure assembly are mounted. A turntable 5 is mounted on the support base 2, which is connected to the machine base 1 via several support columns 3. A drive assembly 4, which drives the turntable 5 to rotate, is mounted on the bottom surface of the support base 2. Several inclined slots 6 are formed on the turntable 5, and sliding rods 7 are slidably connected within these slots. A clamping rod 8 is fixed to the top of each sliding rod 7. A guide assembly on the machine base 1 drives the clamping rod 8 to move inward. Using a press for processing urea sensors, the guide rail 9 of the guide assembly cooperates with the slide base 10 to drive the clamping rod 8 to move precisely along the inclined slots 6 of the turntable 5, achieving centering and clamping of the urea sensor workpiece. This significantly reduces positioning errors, ensures precise alignment of the pressure head 16 with the pressing area, and effectively guarantees the sealing performance and signal transmission stability of the urea sensor.

[0015] Specifically, the pressure assembly includes a straight plate 13, a cylinder 14, a support plate 15, and a pressure head 16. The straight plate 13 is fixed on the machine base 1, the cylinder 14 is set on the straight plate 13, the support plate 15 is located below the straight plate 13, the support plate 15 is connected to the piston rod of the cylinder 14, and the pressure head 16 is fixed to the bottom surface of the support plate 15.

[0016] Specifically, the guide assembly includes a guide rail 9 and a sliding plate 11. The guide rail 9 is fixed on the machine base 1, and a slide block 10 is slidably connected to the guide rail 9. The sliding plate 11 is fixed on the clamping rod 8, and the sliding plate 11 and the slide block 10 are fixedly connected by a support rod 12.

[0017] Specifically, drive component 4 is a motor.

[0018] Operating procedures Place the urea sensor housing between the clamping rods 8 of the turntable 5, activate the guide assembly, and slide the slide 10 along the guide rail 9. The slide plate 11 moves through the support rod 12, and the slide plate 11 drives the clamping rods 8 to retract inward along the inclined groove 6 of the turntable 5 until the clamping rods 8 are tightly attached to the outer wall of the housing, thus completing the centering and fixing of the workpiece. After confirming that the workpiece is accurately positioned and firmly clamped, close the equipment protective door and prepare for the pressing operation.

[0019] The motor of the drive assembly 4 is started, which drives the turntable 5 to rotate, rotating the workstation with the workpiece to below the pressure head 16. The cylinder 14 is started, pushing the support plate 15 and the pressure head 16 to descend, performing sealing or component riveting on the workpiece. After the sealing is completed, the cylinder 14 drives the pressure head 16 to rise and reset. The motor continues to drive the turntable 5 to rotate, transferring the sealed workpiece to the next process station, while transferring new workpieces to be processed to the sealing station, realizing continuous multi-station processing.

[0020] After the processing is completed, turn off the power to the equipment, clean the residual impurities and oil stains on the turntable 5, clamping rod 8 and pressure head 16 to avoid affecting the accuracy of subsequent processing; check the wear of the guide rail 9 and slide 10, and add lubricating oil to ensure smooth sliding; lubricate the motor output shaft of the drive assembly 4 and the rotation shaft of the turntable 5, check the sealing of the cylinder 14, and replace the seals in time if there is any leakage; periodically calibrate the pressure parameters of the pressure head 16 and the station positioning accuracy of the turntable 5, and check the tightness of the support column 3 and the support seat 2 to ensure the long-term stable operation of the equipment.

[0021] Beneficial effects This device effectively solves the problem of low positioning accuracy of traditional presses. Through the cooperation of the guide rail 9 and slide 10 of the guide assembly, the clamping rod 8 is driven to move precisely along the inclined groove 6 of the turntable 5, realizing the centering and clamping of the urea sensor workpiece. The positioning error is significantly reduced, and the pressure head 16 is precisely aligned with the pressing part, effectively ensuring the sealing performance and signal transmission stability of the urea sensor.
