The piston part of the pressing cylinder is provided with an upper pressure plate that can be raised and lowered with it. The upper pressure plate is compatible with the steel pipe mounting groove. A press-fit cylinder is located on the left side of the base, near the steel pipe positioning seat. The piston of the press-fit cylinder has a base plate positioning seat that can move along the X-axis. The base plate positioning seat has a base plate mounting groove facing the steel pipe positioning seat, extending through the upper surface of the base plate positioning seat. A guide channel is located inside the base plate positioning seat, containing a guide block that can move along the X-axis. A positioning cylinder is located on the base plate positioning seat, with its piston connected to the guide block. A retractable positioning rod is located at the end of the guide block away from the positioning cylinder. The top of the positioning rod has a conical truncated cone shaped to fit the inner ring of the steel pipe. A guide through hole, matching the positioning rod and the conical truncated cone, is located on the left inner wall of the base plate mounting groove.

[0005] Furthermore, a compression spring is provided at the end of the guide block that is away from the positioning cylinder, and the end of the compression spring that is away from the guide block is connected to the positioning rod.

[0006] Furthermore, the bottom of the inner sidewalls on both the front and rear sides of the base plate mounting groove is provided with positioning grooves that are compatible with the base plate, and the overall cross-section of the positioning groove and the base plate mounting groove is T-shaped.

[0007] Furthermore, the base plate positioning seat includes a fixed plate, a base plate positioning block, and a set of support columns; the positioning cylinder is set on the outer wall of the base plate positioning block opposite to the steel pipe positioning seat, and the piston part of the press-fit cylinder is connected to the outer wall of the fixed plate opposite to the positioning cylinder; the support columns are set between the fixed plate and the base plate positioning block; the base plate mounting groove and guide channel are formed on the base plate positioning block.

[0008] Furthermore, a left side plate is also provided on the base, and the cylinder barrel of the press-fitting cylinder is located on the left side plate; a lower guide rail extending along the X-axis is also provided on the side of the base located on the press-fitting cylinder, and a left clearance notch is opened at the bottom of the side of the steel pipe positioning seat facing the bottom plate positioning block; the lower guide rail is located between the left side plate and the steel pipe positioning seat, and one end of it extends into the left clearance notch; a lower slide block that can move along the X-axis is provided on the lower guide rail; the bottom of the bottom plate positioning block is located on the lower slide block.

[0009] The beneficial effects of this utility model are as follows: 1. The steel pipe mounting groove is set on a rotatable rotating block, which can accommodate the inclined rod part of the bent steel pipe. The steel pipe positioning notch can position the straight rod part of the bent steel pipe. At the same time, the Y-axis guide slide rail and the guide slide rail, together with the rotating block, can meet the positioning of the inclined rod parts of different bent steel pipes. The guide block with locking function can lock the position of the rotating block after the bent steel pipe is placed in the steel pipe mounting groove and the steel pipe positioning notch to prevent displacement. This solves the problems of high labor intensity, high assembly difficulty, high labor cost, and low assembly efficiency in the assembly of existing oil level sensors with bent steel pipes and base plates, which are achieved manually.

[0010] The clamping cylinder and upper pressure plate, together with the steel pipe mounting groove, can achieve the vertical positioning of bent and straight steel pipes.

[0011] The base plate mounting groove facilitates the placement of the base plate; the base plate mounting groove extends through the upper surface of the base plate positioning seat, facilitating the removal and placement of the base plate and the unloading after assembly; the positioning cylinder, guide block, guide channel, telescopic positioning rod, and conical frustum enable positioning of the base plate during press-fitting, as well as assembly positioning between the base plate and the bent steel pipe, and facilitate smooth unloading after assembly. The press-fitting cylinder, after the positioning cylinder drives the positioning rod and straight / bent steel pipes to complete assembly positioning, guides the bent steel pipe through the conical frustum to fully assemble it into the assembly hole of the base plate, completing the assembly.

[0012] The lower guide rail, lower slider, and base plate positioning block work together to guide the movement of the base plate positioning block during press-fitting cylinder operation, making press-fitting more stable and reliable. The clearance notch design ensures that the lower guide rail's travel distance meets the assembly requirements of the base plate positioning block during assembly.

[0013] The installation of the fixing plate, base plate positioning block, and support column enables simple and reliable fixing of the press-fit cylinder and positioning cylinder, while the split structure facilitates disassembly and assembly.

They are used merely to facilitate the description of positional relationships and should be understood in conjunction with the attached drawings in the specification.

[0023] The above scheme is mainly used to realize the placement and positioning of straight steel pipe 31 and bent steel pipe 32 during assembly, so no further detailed explanation is given for other press-fitting structures.

The specific structure can be flexibly implemented by those skilled in the art based on existing technology and as needed.

[0028] The clamping cylinder 14, pressing cylinder 16, and positioning cylinder 20 are not innovative in their structure, nor are their drive structures innovative points in this case. Therefore, they are not described in detail here. However, since those skilled in the art can flexibly choose to implement them according to existing technology as needed, it does not affect the completeness and feasibility of this solution. Therefore, they are not elaborated here.

[0029] The bottom of the inner sidewalls on both the front and rear sides of the base plate mounting groove 18 is provided with positioning grooves 24 that are compatible with the base plate 34. The overall cross-section of the positioning grooves 24 and the base plate mounting groove 18 is T-shaped.

[0030] The base plate positioning seat includes a fixed plate 25, a base plate positioning block 17, and a set of support columns 26; the positioning cylinder 20 is set on the outer wall of the base plate positioning block 17 away from the steel pipe positioning seat 2, and the piston part of the press-fit cylinder 16 is connected to the outer wall of the fixed plate 25 away from the positioning cylinder 20; the support columns 26 are set between the fixed plate and the base plate positioning block 17; the base plate mounting groove 18 and the guide channel are formed on the base plate positioning block 17.

[0031] The base 1 is also provided with a left side plate 27, and the cylinder part of the press-fit cylinder 16 is provided on the left side plate 27; the base 1 is also provided with a lower guide rail 28 extending along the X-axis on the side of the press-fit cylinder 16, and the bottom of the steel pipe positioning seat 2 facing the bottom plate positioning block 17 has a left clearance notch 29; the lower guide rail is provided between the left side plate 27 and the steel pipe positioning seat 2, and one end of it extends into the left clearance notch 29; the lower guide rail 28 is provided with a sliding block 30 that can move along it along the X-axis; the bottom of the bottom plate positioning block 17 is provided on the sliding block 30.

[0032] A simple explanation of the working principle: When assembling the straight steel pipe 31 and the base plate 34, adjust and fix the position of the pressing block 10. Place one end of the straight steel pipe 31 in the steel pipe positioning notch 9, place the middle section in the steel pipe placement groove 7, and the other end through the right clearance notch 33, facing and approaching the side of the pressing block 10. Then push the end of the straight steel pipe 31 away from the pressing block 10 so that the other end is close to the pressing block 10. The guide slider 5 is locked and the position of the rotating block 6 is fixed. When assembling the bent steel pipe 32 and the base plate 34, remove the pressing stop 10, place the straight part of the bent steel pipe 32 in the steel pipe positioning notch 9, and place the inclined part in the steel pipe placement groove 7. Because the rotating block 6 can rotate and move in conjunction with the guide slider 5, it can meet the placement and positioning of the bent steel pipe 32 with different bending angles. After acceptance, the guide block 19 is locked, and the rotating block 6 is fixed at the position of the Y-axis guide slide rail 4. After the straight steel pipe 31 and the bent steel pipe 32 are installed, the clamping cylinder 14 operates, driving the upper pressure plate 15 downward and pressing it onto the steel pipe installation groove 7, thus holding the straight steel pipe 31 in place. Simultaneously, the positioning cylinder 20 operates, and the positioning rod 22 drives the conical truncated cone 23 to extend out and align with the central assembly hole of the base plate 34. Then, the pressing cylinder 16 operates, driving the base plate positioning seat towards the steel pipe positioning seat 2. The conical truncated cone 23 at the front end of the positioning rod 22 extends into the inner ring of the straight steel pipe 31 and the bent steel pipe 32 facing one end. The continued operation of the piston of the pressing cylinder 16 causes the straight steel pipe 31 and the bent steel pipe 32 to press against the conical truncated cone 23, causing the positioning rod 22 to retract until the straight steel pipe 31 and the bent steel pipe 32 are completely pressed into the central assembly hole of the base plate 34, completing the assembly. After assembly is completed, the clamping cylinder 14, positioning cylinder 20, and pressing cylinder 16 return to their original positions, and the assembled workpiece is manually removed from the notch on the upper end face of the base plate positioning seat in the base plate mounting groove 18.
