[0002] A coordinate measuring machine (CMM) is a modern measuring tool that combines inspection and statistical analysis. It is widely used in various industries, such as for the precision measurement of structures in mold equipment, tooling fixtures, automotive mold parts, and electronic and electrical appliances.

[0003] A search revealed that patent document CN113865534B discloses a coordinate measuring machine (CMM), including a CMM body, a base plate, an adjustment mechanism, and a motor. The CMM body and the base plate slide in a vertical direction. The adjustment mechanism is symmetrically arranged on the base plate, located between the base plate and the CMM body. The adjustment mechanism includes a worm gear, a worm shaft, an adjustment rod, and an adjustment wheel. The worm shaft and the worm wheel are rotatably connected to the base plate and mesh with the worm shaft. One end of the adjustment rod is connected to the worm wheel, and the other end is rotatably connected to the adjustment wheel. The adjustment wheel abuts against the CMM body. The motor is mounted on the base and is linked to the worm shaft. The adjustment rods in the symmetrically arranged adjustment mechanism rotate in opposite directions. This application addresses the problem of difficulty in meeting the operating height requirements of operators of different heights.

[0004] When using this coordinate measuring machine to measure some heavy products, the platform has a certain height, requiring the operator to manually move the product onto the platform, which is quite laborious. Manually moving heavy objects to a height also poses certain safety risks; if the object slips, it may injure the operator. In addition, it does not have the function of positioning the product, and some lighter products placed directly on the platform are prone to shaking, resulting in poor measurement stability and affecting the measurement accuracy. Therefore, a coordinate measuring machine is proposed to solve the above-mentioned problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Please see Figures 1 to 6This embodiment of a coordinate measuring machine includes a base 1, a platform 2 on the top of the base 1, and a coordinate measuring machine body 3 on the upper side of the platform 2. A feeding mechanism is provided on one side of the platform 2. The feeding mechanism includes a fixed frame 4 fixedly connected to the top of the base 1, a top plate 41 fixedly connected to the upper part of the fixed frame 4, a lifting hydraulic cylinder 42 fixedly mounted on the upper side of the top plate 41, and a material rack 43 fixedly mounted on the output shaft of the lifting hydraulic cylinder 42. The material rack 43 is located below the top plate 41. The lifting hydraulic cylinder 42 can drive the material rack 43 to move up and down. Two first guide rods 44 are fixedly mounted on the top of the material rack 43, extending movably through to the top of the top plate 41. The two first guide rods 44 are symmetrically distributed on both sides of the lifting hydraulic cylinder 42. When the material rack 43 moves, it can drive the first guide rods 44 to move synchronously, thus guiding the material rack 43.

[0029] When measuring some heavy products, the lifting hydraulic cylinder 42 can drive the material rack 43 to move downward, so that the heavier products can be placed in the material rack 43. Then the lifting hydraulic cylinder 42 can drive the material rack 43 to move upward, so that the heavier products can be automatically lifted to a higher position, avoiding the safety risks of manually carrying heavy objects to a high position, and also helping to reduce the workload of operators.

[0030] Meanwhile, an mounting plate 45 is fixedly installed on the outer wall of the material rack 43. An opening 49 is provided on the fixed frame 4. The mounting plate 45 passes through the inner side of the opening 49. A pushing hydraulic cylinder 46 is fixedly installed on the upper side of the mounting plate 45. A push plate 47 is fixedly installed on the output shaft of the pushing hydraulic cylinder 46. The push plate 47 is located inside the material rack 43. When the material rack 43 raises the product to the height corresponding to the machine base 2, the pushing hydraulic cylinder 46 can drive the push plate 47 to move, so that the push plate 47 can push the product in the material rack 43 onto the machine base 2 for easy feeding. At the same time, a second guide rod 48 is fixedly installed on the outer wall of the push plate 47 and extends to the outside of the material rack 43. There are two second guide rods 48, which are symmetrically distributed on both sides of the pushing hydraulic cylinder 46. During the movement of the push plate 47, it can drive the second guide rods 48 to move synchronously, which plays a guiding role for the push plate 47.

[0031] It should be noted that a first sliding groove 410 is provided on the inner wall of the opening 49, and a first slider 411 that slides and engages with the first sliding groove 410 is provided on the side of the mounting plate 45. When the material rack 43 moves up and down, it can drive the mounting plate 45 to move up and down along the inner side of the opening 49. With the cooperation of the first slider 411 and the first sliding groove 410, the mounting plate 45 can be guided, which improves the stability of the structure.

[0032] To facilitate product positioning, a positioning mechanism is provided on the outer side of the machine base 2. The positioning mechanism includes a protective plate 5 that is detachably installed on the outer wall of the machine base 2. The protective plate 5 is installed on the outer wall of the machine base 2 by screws. Two fixed seats 51 are fixedly connected to the top of the protective plate 5. Clamping plates 52 are provided on opposite sides of the two fixed seats 51. An electric push rod 53 is provided between the clamping plate 52 and the fixed seat 51. The electric push rod 53 is fixedly installed on the top of the protective plate 5. A connecting block 54 is fixedly installed on the output shaft of the electric push rod 53. A guide groove 58 is provided on the fixed seat 51. One side of the connecting block 54 extends into the inner side of the guide groove 58 and slides with the inner side of the guide groove 58. A connecting rod 55 is provided between the connecting block 54 and the clamping plate 52. The two ends of the connecting rod 55 are movably hinged to the connecting rod 55 and the clamping plate 52, respectively. The electric push rod 53 can drive the connecting block 54 to move along the inner side of the guide groove 58, and drive the clamping plate 52 to move through the connecting rod 55. At the same time, the protective plate 5 is provided with a second sliding groove 56, and the bottom of the clamping plate 52 is provided with a second slider 57 that slides with the second sliding groove 56. Under the guidance of the second sliding groove 56 and the second slider 57, the connecting rod 55 can push the clamping plate 52 to move stably along the second sliding groove 56, thereby adjusting the position of the clamping plate 52. When the two clamping plates 52 move towards each other, they can clamp and position some easily shaking products, improving the stability of measurement. When the two clamping plates 52 move away from each other, they can release the clamping of the product, making it easy to remove.
