Description

Technical Field

[0001] This utility model belongs to the field of measuring equipment technology, specifically relating to a ball-head measuring fixture for surveying. Background Technology

[0002] During the maintenance of hydraulic support cylinders, some cylinders cannot be found in the design drawings. It is necessary to measure the column and jack. When measuring the ball head, test plates are often used. However, the measurement accuracy is low and it is easy to make mistakes. There are many types of test plates, and the tooling is easily damaged and difficult to operate.

[0003] In the fields of machinery manufacturing and automotive parts, the geometric dimensional accuracy (especially the diameter of the ball) of ball-shaped workpieces (such as ball pins and ball heads of spherical bearings) is a key parameter affecting their assembly quality and functional reliability. Currently, conventional methods and equipment for dimensional inspection of such ball-shaped workpieces generally have the following significant drawbacks: Existing methods often rely on manual placement, positioning, measurement, and removal of workpieces, which are cumbersome, time-consuming, and difficult to meet the needs of batch inspection. They lack automated loading and unloading and measurement cycle mechanisms, requiring operator intervention for each workpiece throughout the process, which limits the improvement of overall inspection efficiency. Traditional tooling for fixing ball heads may be complex or unreliable, and displacement may occur during measurement, affecting accuracy. After measurement, especially for ball heads with smooth surfaces, manual removal is often inconvenient, requiring additional tools or careful handling, posing a risk of dropping or damaging the workpiece, and is also inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a ball-head measuring fixture for surveying, which aims to solve the problems raised in the background art.

[0005] A ball-head measuring fixture for surveying includes,

[0006] Control panel;

[0007] The testing assembly, located on the outer wall of the operating table, includes a storage shell, a feeding shell, a linkage rod, a rubber suction cup, a testing platform, a lifting frame, a testing shaft, a washer, and a drive assembly. The storage shell is fixedly installed on both sides of the top of the outer wall of the operating table. The feeding shell is slidably embedded in the inner wall of the storage shell. The linkage rod is rotatably inserted into the two edges of the outer wall of the feeding shell. The rubber suction cup is rotatably inserted into the inner wall of one end of the linkage rod. The outer wall of the feeding shell has an operating groove that matches the rubber suction cup. The lifting frame is fixedly installed at the bottom of the outer wall of the testing platform. The testing platform is located directly below the feeding shell. The testing shaft is slidably embedded in the center of the bottom of the inner wall of the testing platform. The washer is embedded in the groove at the top of the outer wall of the testing platform. The drive assembly is located at the top of the outer side of the operating platform.

[0008] Furthermore, the drive assembly includes a drive cylinder and a lifting cylinder.

[0009] Furthermore, the lifting cylinder is embedded in the inner wall of the operating table, and the output end of the lifting cylinder is fixedly installed at the bottom center of the outer wall of the lifting frame through the operating table. The driving cylinder is fixedly installed on both sides of the outer wall of the operating table, and the output end of the driving cylinder is rotatably inserted into the inner wall of the linkage rod.

[0010] Furthermore, a limit slide rail is fixedly installed on the top of the outer wall of the operating table.

[0011] Furthermore, limit grooves are provided on both sides of the outer wall of the testing platform.

[0012] Furthermore, the limiting slide rail and the limiting groove are matched with each other, and the bottom opening of the inner wall of the feeding shell is matched with the detection table.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The testing components make operation simple and efficient. Workers only need to place the ball head into the specific position in the feeding housing, start the equipment, and the subsequent lifting measurement, rotating the detection shaft to record data, and lowering and automatically ejecting the ball head after measurement are all automatically completed by the equipment. In particular, the design using a rubber suction cup in conjunction with a linkage rod to slowly eject the ball head from the feeding housing makes removing the measured ball head very easy and quick, eliminating the hassle of laborious handling. Measurement accuracy is well guaranteed. The testing platform achieves very smooth vertical lifting movement through a precision lifting frame and limit rail system, ensuring that the detection shaft and washer accurately contact the ball head for measurement, avoiding errors caused by shaking. The washer design also provides a stable contact surface for the ball head. The entire process is safe and reliable. The ball head is stably held between the feeding housing and the testing platform during measurement, preventing accidental slippage. The rubber suction cup ejects the ball head smoothly and controllably, reducing the risk of workpiece damage or ejection. The entire linkage mechanism's motion trajectory is designed and constrained, ensuring stable operation. Attached Figure Description

Then, the testing table 8 enters the inner wall of the receiving shell 2, and then the washer 11 contacts the bottom of the outer wall of the ball. At this time, the testing shaft 10 is rotated, and after recording the data, the testing shaft 10 is reset, and the testing table 8 continues to descend, so that the ball head contacts the feeding shell 3. When it is necessary to discharge the ball head, the driving cylinder 6 is activated, so that the linkage rod 4 rotates, driving the rubber suction cup 5 to approach the ball head, so that the ball head slowly rises and detaches from the feeding shell 3 for easy and quick removal. Before installation, the inner diameter and thickness of the testing table 8 are recorded, and the diameter of the ball head can be calculated by combining the test values ​​of the testing shaft 10.

[0038] Working principle:

[0039] For the testing assembly, first, the operating table 1 is deployed in a suitable working environment. Then, the ball head is placed in the groove of the feeding shell 3. At this time, the lifting cylinder 12 is activated, so that the testing table 8, driven by the lifting frame 9, and the limiting groove 801 of the testing table 8, rises vertically under the action of the limiting slide rail 7.
