It has the characteristics of simple mechanical structure, small size, light weight, large measuring range, flexibility and convenience, and can be measured on site.

[0003] In the prior art, Chinese patent publication number CN211085018U discloses an articulated coordinate measuring machine with adaptive variable measurement space. Existing articulated coordinate measuring machines cannot adjust the measurement range according to the position of the workpiece. The utility model includes a base, a first rotary joint, a first swing joint, a second rotary joint, a second swing joint, a third rotary joint, a third swing joint, a primary measuring arm, a secondary measuring arm, a probe, a first shearing telescopic mechanism and a second shearing telescopic mechanism; the bottom end of the first shearing telescopic mechanism is connected to the first swing joint, and the top end is fixed to the bottom end of the primary measuring arm; the secondary measuring arm is fixed to one end of the second shearing telescopic mechanism; the other end of the second shearing telescopic mechanism is connected to the third swing joint through the third rotary joint. The utility model realizes active control of the variable measurement space for workpieces of different sizes and positions to ensure measurement accuracy.

[0004] However, when the utility model is actually used, the articulated coordinate measuring machine usually has its own weight, which makes it inconvenient to move the coordinate measuring machine. When used on a workbench, it is inconvenient to fix the coordinate measuring machine and the table, which may easily cause tipping and shaking due to accidental contact. Therefore, improvement is needed. Utility Model Content

[0005] The utility model aims to provide an articulated coordinate measuring machine with adaptive measurement, which can avoid the phenomenon of shaking, is safer and improves the overall stability.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an articulated coordinate measuring machine with adaptive measurement, comprising a base, a universal wheel is arranged at the bottom of the base, a threaded hole is opened inside the base, a threaded rod is threadedly connected to the inner wall of the threaded hole, the top of the threaded rod is fixedly connected with an anti-slip torque, the bottom of the threaded rod is fixedly connected with a fixing plate, the bottom of the fixing plate is fixedly connected with a shock-absorbing ring, the bottom of the shock-absorbing ring is fixedly connected with an anti-slip ring, the bottom of the fixing plate is fixedly connected with a cylinder, the output end of the cylinder is fixedly connected with a telescopic rod, and the bottom of the telescopic rod is fixedly connected with a suction cup.

[0007] By adopting the above technical solution, when the staff is in use, the base can be easily moved by the universal wheel. When it is moved to a suitable position, the anti-skid knob is twisted to drive the threaded rod to rotate on the inner wall of the threaded hole. The fixed plate moves downward with the rotation of the threaded rod, so that the anti-skid ring contacts the work surface. The anti-skid ring has a strong anti-skid effect. After contacting the table, it pushes the base to make the universal wheel difficult to rotate. Then the cylinder is started to drive the telescopic rod to extend downward, driving the suction cup to press down and adsorb on the table, so that the base is fixed. The shock-absorbing ring has a shock-absorbing effect, so that after the base is fixed, it can avoid shaking during detection and use, which is safer and improves the overall stability.

[0008] The utility model is further configured as follows: a pad is fixedly connected to the top of the base, and a rotating cylinder is fixedly connected to the top of the pad.

[0009] By adopting the above technical solution, the rotating cylinder is fixed above the pad, and the rotating cylinder can be started when in use.

[0010] The utility model is further configured as follows: the output end of the rotary cylinder is fixedly connected with a rotating disk, and the top of the rotating disk is fixedly connected with a rotating seat.

[0011] By adopting the above technical solution, the turntable can be rotated under the drive of the rotating cylinder, so that the rotating seat can be rotated.

[0012] The utility model is further configured as follows: a sleeve is fixedly connected to the top of the pad, and an annular groove is provided on the outer surface of the sleeve.

[0013] By adopting the above technical solution, the rotating seat rotates on the outer surface of the sleeve, which has stronger stability.

[0016] The utility model is further configured as follows: a rotating arm is fixedly connected to the top of the rotating seat, and a first joint arm is rotatably connected to the top of the rotating arm.

[0017] By adopting the above technical solution, the rotating arm can rotate in position, and the first joint arm can rotate at the top of the rotating arm.

[0018] The utility model is further configured as follows: one end of the first joint arm is fixedly connected to a damping rod, and an outer surface of the damping rod is fixedly connected to a damping layer.

[0019] By adopting the above technical solution, the damping layer on the damping rod increases resistance during rotation, so that the rotating connection has damping.

[0020] The utility model is further configured as follows: one end of the first joint arm is rotatably connected to the second joint arm, and the top of the second joint arm is rotatably connected to the third joint arm.

[0021] By adopting the above technical solution, the rotation connection between the second joint arm and the third joint arm is also provided with damping, so the stability is stronger during adjustment.

[0023] By adopting the above technical solution, the fourth joint arm and the adjustment arm increase the range of adjustment bending, and the adjustment range is larger and more flexible, so that it can adapt to a relatively limited measurement space.

[0024] The utility model is further configured as follows: the bottom of the adjusting arm is rotatably connected to an adjusting seat, and the bottom of the adjusting seat is fixedly connected to a coordinate measuring head.

[0025] By adopting the above technical solution, the adjustment seat is rotated downward to adjust the inclination angle of the coordinate measuring head, so that the coordinate measuring head is more flexible in use.

[0026] The beneficial effects of the utility model are:

[0027] 1. The utility model, through the coordinated arrangement among the base, universal wheels, threaded holes, threaded rods, anti-skid twists, fixing plates, shock-absorbing rings, anti-skid rings, cylinders, telescopic rods and suction cups, can make the device in use. When in use, the staff can conveniently move the base through the universal wheels. When moving to a suitable position, the staff twists the anti-skid twists to drive the threaded rods to rotate on the inner wall of the threaded holes. The fixing plates move downward along with the rotation of the threaded rods, so that the anti-skid rings contact with the working table. The anti-skid rings have a strong anti-skid effect. After contacting with the table, the base is pushed, so that the universal wheels are not easy to rotate. Subsequently, the cylinder is started to drive the telescopic rods to extend downward, driving the suction cups to be pressed down and adsorbed on the table, so that the base is fixed. The shock-absorbing ring has a shock-absorbing effect, so that after the base is fixed, when it is used for detection, it can avoid shaking, which is safer and improves the overall stability.

The rotating seat drives the slider to rotate on the inner wall of the annular groove under the rotation, and the rotating arm can rotate in direction, and the first joint arm can rotate at the top of the rotating arm. The damping layer on the damping rod increases the resistance during rotation, so that the rotating connection has damping. The rotating connections of the second joint arm and the third joint arm also have damping, and have stronger stability during adjustment. The fourth joint arm and the adjusting arm increase the range of adjustment tortuosity, and the adjustment range is larger and more flexible, so that it can adapt to a more limited measurement space.
