Description

Technical Field

[0001] This utility model relates to the field of distance measurement technology, and in particular to a device for detecting the center distance of an upper thrust rod seat. Background Technology

[0002] A push rod is a component formed by hinged sleeve assembly to the mounting hole of a push rod ball joint. It is mainly used in the suspension structure of automobiles. Since there are many types of automobile suspensions, different automobiles need to use push rods with different center distances. Currently, the main method for measuring the center distance of push rods is to use a measuring tape. One end of the measuring tape is pressed into the mounting hole at one end of the push rod, and then the measuring tape is pulled so that it passes over the mounting hole at one end of the push rod. The distance between the centers of the two mounting holes is then measured to obtain the wheelbase. This method is simple and easy to use, but the measurement error is relatively large.

[0003] For example, a center distance detection device for an upper thrust rod seat disclosed in Chinese patent literature (publication number: CN221055698U) allows for easy adaptation to the length of the thrust rod by adjusting the distance between two fixed components through rotating the threaded rod. The two ends of the thrust rod can be placed on the two fixed components respectively, and the two fixed components can be used to fix the two ends of the thrust rod, so that the center point of the fixed components is on the same vertical line as the center point of the thrust rod mounting hole. Then, the center distance of the thrust rod can be obtained by the position of the two pointers on the length line, which is convenient, accurate and has small error.

[0004] However, when fixing the two ends of the thrust rod during testing, the screw needs to be manually operated. The screw also needs to be rotated during disassembly. Furthermore, when operating the screw to open the backing plate, another operator is required to fine-tune the slider. The whole process is cumbersome, which not only greatly reduces the testing efficiency but also easily leads to coordination errors that reduce the accuracy of the test. Utility Model Content

[0028] like Figure 1-5 As shown, this utility model provides a technical solution: a center distance detection device for an upper thrust rod seat, including a detection platform 1. The detection platform 1 serves as the basic platform of the entire upper thrust rod seat center distance detection device, playing a crucial supporting and fixing role. It is usually made of sturdy and durable metal materials, with high strength and stability, to ensure that no deformation or shaking occurs during the detection process.

[0029] The upper surface of the testing table 1 is provided with a moving groove 2. An automatic fine-tuning mechanism is set inside the moving groove 2. The automatic fine-tuning mechanism includes a lead screw 3. One end of the lead screw 3 is rotatably connected to the inner wall of one side of the moving groove 2 through a bearing. The other end of the lead screw 3 passes through the moving groove 2 and extends to one side of the testing table 1. A servo motor 31 is fixedly installed on one side of the testing table 1. The output shaft of the servo motor 31 is fixedly connected to the other end of the lead screw 3 through a coupling. The lead screw 3 is one of the core components of the automatic fine-tuning mechanism. One end of it is rotatably connected to the inner wall of one side of the moving groove 2 through a high-precision bearing. This connection method ensures the stability and accuracy of the lead screw 3 during rotation, while also reducing frictional resistance.

[0030] The lead screw 3 is externally threaded with a threaded block 32. The outside of the threaded block 32 is slidably connected to the inner wall of the moving groove 2. An adjusting block 33 is fixedly connected to the upper end of the threaded block 32. A guide groove 34 is provided at the upper end of the adjusting block 33. An adjusting slider 35 is slidably connected to the inner wall of the guide groove 34. The adjusting block 33 moves with the movement of the threaded block 32. The adjusting block 33 is usually made of metal material and has high strength and stability. The guide groove 34 at the upper end of the adjusting block 33 provides a track for the movement of the adjusting slider 35. The inner wall of the guide groove 34 is precision machined to ensure a tight fit with the outside of the adjusting slider 35, so as to ensure the stability and straightness of the adjusting slider 35 during the movement.

[0031] The two sides of the adjusting slider 35 are fixedly connected with symmetrically distributed support springs 36. One end of the support spring 36 is fixedly connected to the inner wall of one side of the guide groove 34. The function of the support spring 36 is to provide a certain elastic support so that the other placement platform 4 can automatically adjust its position within a certain range to adapt to the requirements of the thrust rod length change and center distance detection.

[0032] A support and fixing mechanism is provided above the testing table 1, and the support and fixing mechanism includes a placement platform 4. The lower end of one placement platform 4 is fixedly connected to the upper end of the testing table 1, and the lower end of the other placement platform 4 is fixedly connected to the upper end of the adjusting slider 35. The placement platform 4 is an important component of the support and fixing mechanism, used to place and support the thrust rod, and the two placement platforms 4 are at the same height.

[0033] The upper end of the placement platform 4 is fixedly connected to the mounting housing 41, and the inner bottom wall of the mounting housing 41 is fixedly installed with the servo motor 42. The mounting housing 41 provides space for the installation and protection of the servo motor 42 and other related components.

[0034] The output shaft of the servo motor 42 is fixedly mounted with a rotating shaft 43 via a coupling. One end of the rotating shaft 43 is fixedly connected to a drive disk 44. When the servo motor 42 starts, the rotating shaft 43 will rotate under the drive of the servo motor 42, thereby driving the drive disk 44 to rotate.

[0035] The upper end of the drive disk 44 is provided with inclined grooves 45 arranged in a ring array, and the inner top wall of the mounting housing 41 is provided with limiting grooves 46 arranged in a ring array. The inclined grooves 45 are slidably inserted into the lower end of the drive rod 48. When the drive disk 44 rotates, the inclined grooves 45 will drive the drive rod 48 to move, thereby realizing the adjustment of the position of the arc-shaped support block 410.

[0036] The inner wall of the limiting groove 46 is slidably connected to the limiting slider 47. The lower end of the limiting slider 47 is fixedly connected to the drive rod 48. The limiting slider 47 will slide in the limiting groove 46, thereby limiting the movement direction of the drive rod 48 and ensuring that the arc-shaped support block 410 can accurately provide internal support and fixation to the inner wall of the thrust rod mounting hole.

[0037] The lower end of the drive rod 48 is slidably inserted into the inner wall of the inclined groove 45. A telescopic rod 49 is fixedly connected to the outside of the drive rod 48. When the drive rod 48 moves, it will drive the telescopic rod 49 to extend or retract, thereby adjusting the position of the arc-shaped support block 410.

[0038] One end of the telescopic rod 49 passes through and extends to the outside of the mounting housing 41. One end of the telescopic rod 49 is fixedly connected to an arc-shaped support block 410. The arc-shaped support block 410 is usually made of high-strength metal material, with high hardness and wear resistance. Its surface is usually also provided with anti-slip devices, such as rubber pads or anti-slip textures, to prevent the thrust rod from sliding during the support and fixing process.

[0039] Another placement platform 4 is externally fixedly connected to a pointer 411. A scale groove 412 is provided above the detection platform 1, and the starting end of the scale groove 412 is on the same axis as the center of one of the placement platforms 4. The operator can understand the center distance of the thrust rod by observing the value of the scale groove 412 pointed to by the pointer 411.

[0040] The working process of this utility model:

[0041] Step 1: Start the servo motor 31 according to the length of the push rod. The servo motor 31 drives the lead screw 3 to rotate. The rotation of the lead screw 3 drives another placement platform 4 to move through the threaded block 32 and the adjusting block 33. After moving it to the approximate length of the push rod, stop the servo motor 31.

[0042] Step 2: Insert the mounting holes at both ends of the thrust rod into the outside of the mounting housing 41 and make its lower end contact the placement platform 4. Start the servo motor 42 to drive the rotating shaft 43 to rotate. The rotation of the rotating shaft 43 drives the drive disk 44 to rotate. The rotation of the drive disk 44 drives the drive rod 48 to move through the inclined groove 45. The movement of the drive rod 48 stabilizes the extension of the telescopic rod 49 through the cooperation of the limiting slide groove 46 and the limiting slider 47. The synchronous extension of multiple telescopic rods 49 drives the arc-shaped support block 410 to provide internal support and fixation to the inner wall of the thrust rod mounting hole.

[0043] Step 3: Since one of the placement platforms 4 is fixed to the upper end of the testing platform 1, when the two ends of the push rod are internally supported and fixed, the other end of the push rod will be moved by force. At this time, due to the self-locking characteristics of the lead screw 3 and the threaded block 32, the other placement platform 4 will move by adjusting the slider 35. At this time, one of the support springs 36 will be compressed by force, and the movement of the other placement platform 4 will drive the pointer 411 to move. The operator can understand the center distance of the push rod by observing the value of the pointer 411 pointing to the scale groove 412.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
