Description

Technical Field

[0001] This utility model relates to the technical field of protective structures for coordinate measuring machines (CMMs), and more particularly to a probe protective structure for a CMM. Background Technology

[0002] A coordinate measuring machine (CMM) is a precision measuring instrument that determines the spatial coordinates of measuring points on a workpiece by moving along the X, Y, and Z axes. It can measure parts of various complex shapes with high precision and is widely used in fields such as machinery manufacturing, automotive industry, and aerospace. It can detect dimensional, shape, and positional errors to ensure product quality.

[0003] Chinese patent CN219368697U discloses a probe protection structure for a coordinate measuring machine (CMM). The key technical features include: a rounded corner mounting plate; a probe protective sleeve fixedly mounted on the inner side of the rounded corner mounting plate; a rounded corner protective outer shell fixedly mounted on the lower surface of the rounded corner mounting plate near the inner side; screw through holes near the four corners on the upper surface of the rounded corner mounting plate; a rounded corner compression mechanism fixedly mounted on the inner side of the rounded corner protective outer shell; and the probe protective sleeve comprising a fixed inner liner, a sponge outer sleeve, a conical hollow sponge long sleeve, a conical hollow sponge short sleeve, an elastic rubber sleeve, and an annular groove. This CMM probe protection structure, through the rounded corner compression mechanism and the probe protective sleeve, can protect multiple probes of varying lengths and thicknesses. The operation and installation process is simple and quick, and it provides cushioning and shock absorption, resulting in higher safety and preventing collisions between probes and damage from impacts by heavy objects.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: In the probe protection structure for storing coordinate measuring machines, debris can easily enter the probe protection structure of the coordinate measuring machine. When the probe protection structure of the coordinate measuring machine is used again, the debris can easily adhere to the probe, thereby affecting the test results.

[0005] Therefore, this utility model provides a probe protection structure for a coordinate measuring machine. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing coordinate measuring machine (CMM) probe protection structures, where debris easily enters and adheres to the probe when the CMM is reused, thus affecting the testing results. Therefore, this invention proposes a CMM probe protection structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a probe protection structure for a coordinate measuring machine, comprising a rounded corner mounting plate, a rounded corner protective shell fixedly mounted on the surface of the rounded corner mounting plate, a fixing frame fixedly mounted on the surface of the rounded corner protective shell, a take-up drum rotatably mounted on the surface of the fixing frame, a rotating drum fixedly mounted on the surface of the take-up drum, the inner wall of the rotating drum being rotatably connected to the fixing frame, a pressing rod being threadedly connected inside the rotating drum, a gripping block fixedly mounted on the surface of the pressing rod, a shielding cloth fixedly mounted on the surface of the take-up drum, an iron plate fixedly mounted on the end of the shielding cloth away from the take-up drum, two locking holes being formed on the surface of the iron plate, and two hanging brackets fixedly mounted on the surface of the rounded corner protective shell, the size of the hanging brackets being adapted to the size of the locking holes.

[0008] The combined effect of the above components is that when storing the probe protection structure of the coordinate measuring machine, the probe protection structure of the coordinate measuring machine can be shielded, preventing foreign objects from entering the probe protection structure of the coordinate measuring machine. This avoids the problem of foreign objects adhering to the probe and affecting the test results when using the probe protection structure of the coordinate measuring machine.

[0009] Preferably, the surface of the rounded corner mounting plate has two rectangular grooves, and a fixing rod is fixedly inserted into the inner wall of the rectangular groove. The arc surface of the fixing rod is rotatably fitted with a rolling cylinder, and the surface of the rolling cylinder abuts against the shielding cloth.

[0010] The effect achieved by the above components is that the shielding cloth can move along the surface of the rolling cylinder, reducing the friction between the shielding cloth and the rounded corner mounting plate, thereby reducing the damage to the shielding cloth caused by friction.

[0011] Preferably, a magnet is fixedly installed on the surface of the rounded corner protective shell.

[0012] The effect achieved by the above components is that the magnet can attract the iron plate, thus preventing the rolled-up covering cloth from unraveling.

[0013] Preferably, the outer arc of the winding drum is fitted with a baffle.

[0014] The effect achieved by the above components is that the baffle can help store the covering cloth.

[0015] Preferably, a balancing frame is fixedly installed on the surface of the baffle, a cleaning pad is snapped onto the surface of the balancing frame, and the surface of the cleaning pad is slidably connected to the shielding cloth.

[0016] The effect achieved by the above components is that the cleaning pad can remove debris from the cover cloth.

[0017] Preferably, the cleaning pad has a U-shaped cross-section.

[0018] The effect achieved by the above components is that the U-shaped cleaning pad can be easily attached to the balance frame.

[0019] Preferably, both of the hanging brackets have anti-slip textures on their surfaces, and the cross-section of the hanging brackets is "L" shaped.

[0020] The effect achieved by the above components is that the anti-slip texture on the bracket can reduce the friction between the bracket and the iron plate.

[0021] In summary:

[0022] In this invention, the probe protection structure of a coordinate measuring machine can be shielded when storing the probe, preventing debris from entering the probe protection structure and thus avoiding the problem of debris adhering to the probe and affecting the test results when using the probe protection structure.

Detailed Implementation

[0028] Reference Figure 1-4As shown, this utility model provides a technical solution: a probe protection structure for a coordinate measuring machine, including a rounded corner mounting plate 1, a rounded corner protective shell 2 fixedly mounted on the surface of the rounded corner mounting plate 1, a fixing frame 4 fixedly mounted on the surface of the rounded corner protective shell 2, a take-up drum 12 rotatably sleeved on the surface of the fixing frame 4, a rotating drum 10 fixedly mounted on the surface of the take-up drum 12, the inner wall of the rotating drum 10 rotatably connected to the fixing frame 4, a pressing rod 14 threadedly connected inside the rotating drum 10, a gripping block 15 fixedly mounted on the surface of the pressing rod 14, a shielding cloth 3 fixedly mounted on the surface of the take-up drum 12, an iron plate 16 fixedly mounted on the end of the shielding cloth 3 away from the take-up drum 12, two locking holes 17 formed on the surface of the iron plate 16, two hanging brackets 11 fixedly mounted on the surface of the rounded corner protective shell 2, the size of the hanging brackets 11 matching the size of the locking holes 17, two rectangular grooves 5 formed on the surface of the rounded corner mounting plate 1, a fixing rod 7 fixedly inserted into the inner wall of the rectangular groove 5, the arc surface of the fixing rod 7... A rotating sleeve with a rolling drum 6 is fitted with a shielding cloth 3. The surface of the rolling drum 6 abuts against the shielding cloth 3, allowing the shielding cloth 3 to move along the surface of the rolling drum 6. This reduces the friction between the shielding cloth 3 and the rounded corner mounting plate 1, thereby reducing damage to the shielding cloth 3 caused by friction. A magnet 18 is fixedly installed on the surface of the rounded corner protective shell 2. The magnet 18 can attract the iron plate 16, preventing the shielding cloth 3 from unraveling after winding. A baffle 13 is fitted on the outer arc of the winding drum 12. The baffle 13 can assist in storing the shielding cloth 3. A balance frame 9 is fixedly installed on the surface of the baffle 13. A cleaning pad 8 is snapped onto the surface of the balance frame 9. The surface of the cleaning pad 8 is slidably connected to the shielding cloth 3. The cleaning pad 8 can remove debris from the shielding cloth 3. The cross-section of the cleaning pad 8 is "U". The U-shaped cleaning pad 8 can be easily snapped onto the balance frame 9. The surfaces of the two hangers 11 are provided with anti-slip textures. The cross-section of the hangers 11 is "L". The anti-slip textures on the hangers 11 can reduce the friction between the hangers 11 and the iron plate 16.

[0029] Working principle: When the probe protection structure of the coordinate measuring machine needs to be stored, the iron block is pulled, and the iron block moves with the help of the shielding cloth 3. At this time, the shielding cloth 3 unfolds, so that the shielding cloth 3 covers the probe protection structure of the coordinate measuring machine. When the iron block is fitted onto the hanger 11 through the clamping hole 17, the rotating drum 10 is rotated. The rotation of the rotating drum 10 drives the winding drum 12 to rotate, and the rotation of the winding drum 12 drives the shielding cloth 3 to move. When the shielding cloth 3 tightens, the rotation of the rotating drum 10 is stopped, and then the grip block 15 is rotated. The grip block 15 rotates. Simultaneously, the extrusion rod 14 rotates, and the extrusion rod 14 moves towards the fixed frame 4 via the thread. After the extrusion rod 14 moves a certain distance, its surface presses against the fixed frame 4. At this time, the fixed frame 4 and the rotating cylinder 10 are fixed together, and the shielding cloth 3 is also fixed. The shielding cloth 3 can then shield the probe protection structure of the coordinate measuring machine, preventing debris from entering the probe protection structure. When the probe protection structure of the coordinate measuring machine needs to be used, the grip block 15 is rotated. The grip block 15 rotates simultaneously with the... The pressing rod 14 rotates, and moves away from the fixed frame 4 via the screw thread. After moving a certain distance, the surface of the pressing rod 14 no longer presses against the fixed frame 4. At this point, the fixed frame 4 and the rotating cylinder 10 are no longer fixed, and the shielding cloth 3 is also no longer fixed. At this time, the iron frame is removed from the hanging bracket 11, and then the rotating cylinder 10 is rotated. The rotation of the rotating cylinder 10 drives the winding drum 12 to rotate. During the rotation of the winding drum 12, the winding drum 12 winds up the shielding cloth 3, and the shielding cloth will be wound along the baffle 13. During this process, the cleaning pad 8 removes debris from the shielding cloth 3. After the shielding cloth 3 is rolled up, the iron plate 16 is placed on the magnet 18. At this time, the magnet 18 attracts the iron block, so that the rolled-up shielding cloth 3 will not unravel. When storing the probe protection structure of the coordinate measuring machine, the probe protection structure of the coordinate measuring machine can be shielded, so that debris cannot enter the probe protection structure of the coordinate measuring machine, thereby avoiding the problem of debris adhering to the probe and affecting the detection results when using the probe protection structure of the coordinate measuring machine.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
