Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a gauge, particularly a quick position gauge for a push rod assembly. Background Technology

[0002] A positional gauge is a specialized inspection device used to measure and evaluate the dimensional quality of parts. It is mainly used to detect the positional errors of elements such as holes and shafts on parts. Push rod assemblies are commonly used automotive parts. During the processing of push rod assemblies, it is necessary to inspect their dimensions, so a positional gauge is required.

[0003] For example, Chinese patent literature discloses a position measurement gauge [Application No.: 202321791829.9; Authorization Announcement No.: CN220437279U], which includes a base plate, a motor fixedly mounted on the base plate, a double drive sprocket fixedly connected to the output shaft of the motor, a lifting assembly on the double drive sprocket, and the double drive sprocket rotatably connected to the base plate, a base fixedly connected to the lifting assembly, and two cylinders symmetrically fixedly connected to the base, a placement box fixedly connected to the top left side of the base, a push rod motor fixedly mounted on the placement box, a fixed plate fixedly connected to the output shaft of the push rod motor, and a detection gauge fixedly connected to the fixed plate, and a moving assembly at the bottom of the base plate.

[0004] The aforementioned position gauge can adjust the height of the base according to actual needs and facilitate overall movement. However, it is not convenient to fix the workpiece. During the inspection process, the relative position of the gauge and the cylinder needs to be constantly adjusted, making the operation process relatively complicated. Furthermore, the inspection is not accurate enough due to the manual observation of the gauge's adjustment position. When mass production inspection is required, the device is slow and cannot meet the needs of mass production. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a quick position gauge for push rod assemblies that facilitates workpiece fixing and automatic detection.

[0006] The objective of this utility model can be achieved through the following technical solution: A rapid position measurement tool for a push rod assembly includes a detection block. A detection point is provided on the left side of the top of the detection block. A pushing assembly is fixedly installed on the rear side of the top of the detection block. The pushing assembly includes an adjusting cylinder, which is fixedly installed on the rear side of the top of the detection block. A clamping seat is fixedly connected to the telescopic end of the adjusting cylinder. An adjusting sleeve is movably fitted onto the bottom surface of the adjusting cylinder. A positioning plate is fixedly connected to the rear side of the top of the adjusting sleeve. A bolt is installed on the rear side of the adjusting sleeve. The clamping... A push rod is clamped and installed in the inner cavity of the seat. A detection point is provided on the right side of the detection block. A horizontal plate is fixedly installed at the bottom right side of the detection block. A dovetail groove is provided at the top of the horizontal plate. A pushing assembly is fixedly installed at the top of the horizontal plate. The pushing assembly includes a motor. The motor is fixedly installed on the right side of the top of the horizontal plate. A screw is fixedly connected to the surface of the motor output shaft. A movable plate is sleeved on the surface of the screw. An installation sleeve is fixedly connected to the top of the movable plate. The push rod is installed in the inner cavity of the installation sleeve. A bolt is installed at the top of the installation sleeve.

[0007] This rapid position gauge for push rod assembly simultaneously detects the push rod assembly by dividing it into two parts. Pushing component one and pushing component two fix and push the two parts of the push rod assembly respectively, so that the two parts of the push rod assembly are automatically pushed to detection point one and detection point two for detection, which greatly improves the detection efficiency. During the detection process, there is no need for frequent manual adjustments. The overall operation is simple and convenient for staff to operate.

[0008] In the aforementioned rapid positioning fixture for the push rod assembly, the surface of bolt one is threadedly connected to the rear side of the adjusting sleeve, and the rear side of bolt one penetrates into the inner cavity of the adjusting sleeve and is in close contact with the surface of the adjusting cylinder. The bolt one allows the adjusting sleeve to be stably fixed to the surface of the adjusting cylinder, enabling the adjusting sleeve to be adjusted to different heights as needed. It also allows for adjustment of the positioning plate, and the adjusting plate is used to position the descent distance of the clamping seat.

[0009] In the aforementioned rapid positioning fixture for the push rod assembly, the bottom of the moving plate has a dovetail structure, extending into the inner cavity of the dovetail groove and making sliding contact with its inner wall. The dovetail structure of the dovetail groove and the moving plate ensures stable sliding of the moving plate within the dovetail groove and also limits its movement, preventing wobbling during its motion.

[0010] In the aforementioned rapid positioning gauge for the push rod assembly, the surface of the second bolt is threaded to the top of the mounting sleeve, and the bottom of the second bolt penetrates into the inner cavity of the mounting sleeve and is in close contact with the surface of the second push rod. The second bolt ensures that the second push rod is stably fixed inside the mounting sleeve, preventing deviation when it is inserted into the detection strip and improving detection accuracy.

[0011] In the aforementioned quick positioning fixture for the push rod assembly, the clamping seat is made of PET material, and the inner wall of the clamping seat is in contact with the surface of the push rod component. The PET material allows the clamping seat to deform, making it easier for the push rod component to be inserted into the clamping seat and fixed, thus improving the ease of assembly and disassembly.

[0012] In the aforementioned rapid position calibration fixture for the push rod assembly, the left side of the screw and the right side of the detection block are rotatably connected via a bearing, and the surface of the screw is threadedly connected to the connection point of the moving plate. This threaded connection ensures that the moving plate moves under the action of the thread, allowing the moving plate to perform position calibration by mounting the sleeve and push rod.

[0013] Compared with existing technologies, the advantages of this push rod assembly rapid position measurement fixture are as follows: by dividing the push rod assembly into two parts for simultaneous detection, and using push component one and push component two to fix and push the two parts of the push rod assembly respectively, the two parts of the push rod assembly are automatically pushed to detection point one and detection point two for detection, which greatly improves the detection efficiency. Moreover, the fixing effect is stable, and no manual adjustment is required, which effectively ensures the detection accuracy and improves the detection efficiency, making it suitable for mass production.
