Description

Technical Field

[0001] The utility model relates to the technical field of three - coordinate measuring machine protection, and particularly relates to a probe protection structure for a three - coordinate measuring machine. Background Art

[0002] In modern industrial production, as a high - precision measuring device, the three - coordinate measuring machine is widely used in various fields. However, during the actual measurement process, the safety and stability of the probe are crucial. Since the measurement work is often carried out in a complex and changeable environment and different types of probes are required, different types of probes need to be adapted to different fixed storage devices during storage. However, it is difficult to quickly and effectively stably clamp a variety of types of probes in the existing devices, resulting in the probes being prone to shaking or deviation during storage, and even may cause collision damage between the probes. On the other hand, the probe may be hit by heavy objects or collided with other external objects, and the traditional protection means are insufficient and cannot provide sufficient protection for the probe, resulting in the probe being easily damaged and its service life being shortened. To sum up, in order to solve the problems of inconvenient storage, insufficient protection, and inconvenient operation of the existing three - coordinate measuring machine probes, it has become an urgent task to develop a probe protection structure that can quickly clamp different types of probes, effectively protect them, and is easy to operate.

[0018] The outer wall of the fixed cylinder 31 is fixedly connected to the inner wall of the fixed frame 2, the outer wall of the clamping block 33 is slidably connected to the outer wall of the extrusion block 32, and the end of the push spring 37 away from the extrusion block 32 is fixedly connected to the inner wall of the fixed cylinder 31. The upward movement of the extrusion block 32 will push the clamping block 33 slidably connected thereto to rotate on the inner wall of the fixed cylinder 31, and the rubber block 34 rotatably connected to the bottom end of the clamping block 33 contacts the probe, thereby realizing the clamping and fixing of the probe.

[0019] A limiting groove 38 is formed in the wall of the sliding rod 36. A push rod 39 is arranged on the outer wall of the sliding rod 36. A clamping block 310 is fixedly connected to the outer wall of the push rod 39. A return spring 311 is fixedly connected to the outer wall of the clamping block 310. The sliding rod 36 is slidably connected to the top end of the fixed cylinder 31 through a fixing block. The outer wall of the clamping block 310 is slidably connected to the inner wall of the limiting groove 38. The limiting groove 38 formed in the wall of the sliding rod 36 cooperates with the clamping block 310 fixedly connected to the push rod 39. The clamping block 310 is clamped into the limiting groove 38 under the action of the fixedly connected return spring 311, realizing the fixation of the position of the sliding rod 36.

[0020] The protection device 4 includes a fixed ring 41. A screw rod 44 is threadedly connected to the inner wall of the fixed ring 41. A corrugated pipe 43 is fixedly connected to the outer wall of the fixed ring 41. The bottom end of the screw rod 44 is rotatably connected to a moving ring 42. A limiting rod 45 is fixedly connected to the outer wall of the moving ring 42. The inner wall of the fixed ring 41 is slidably connected to the outer wall of the fixed cylinder 31. The bottom end of the corrugated pipe 43 is fixedly connected to the outer wall of the moving ring 42. The outer wall of the limiting rod 45 is slidably connected to the inner wall of the fixed ring 41. By rotating the screw rod 44, the screw rod 44 pushes the rotatably connected moving ring 42 to move. Through the sliding of the limiting rod 45 in the fixed ring 41, the moving ring 42 moves downward, thereby driving the corrugated pipe 43 to expand or contract.

[0021] Working principle:

[0022] During use, the probe is installed in the fixing device 3 in the upper fixing frame 2 of the bracket 1. When the probe is placed in the fixed cylinder 31, the probe upwardly presses the pressing block 32, causing the pressing block 32 to move upward. The buffer pad 35 at its bottom end plays a buffering role. At the same time, the upward movement of the pressing block 32 will push the clamping block 33 slidably connected thereto to rotate. The rubber block 34 at the bottom end of the clamping block 33 contacts the probe, thereby realizing the clamping and fixing of the probe. During the movement of the pressing block 32, the sliding rod 36 at the top end slides in the fixed cylinder 31. The limiting groove 38 in the wall of the sliding rod 36 cooperates with the clamping block 310 on the push rod 39. The clamping block 310 is clamped into the limiting groove 38 under the action of the return spring 311, realizing the fixation of the position of the sliding rod 36, thereby ensuring the stable position of the pressing block 32 and ensuring the firm clamping of the probe. When the probe needs to be removed, pull the push rod 39 so that the clamping block 310 no longer clamps into the limiting groove 38. At this time, under the action of the pushing spring 37, the pressing block 32 moves downward, so that the clamping block 33 releases the fixation of the probe;

[0023] In terms of protection, the fixed ring 41 in the protection device 4 is sleeved outside the fixed cylinder 31. By rotating the screw rod 44, the screw rod 44 pushes the moving ring 42. Through the sliding of the limiting rod 45 in the fixed ring 41, the moving ring 42 moves downward, thereby driving the corrugated pipe 43 to expand or contract, realizing the protection adjustment of the probe and preventing the measuring head from being damaged by collision.
