Technical Field
[0001] This utility model relates to the field of mechanical testing technology, and in particular to a high-precision three-coordinate measuring device for precision machinery. Background Technology
[0002] In modern manufacturing, the machining accuracy of precision machinery directly determines the performance and quality of products. Coordinate measuring machines (CMMs), as key equipment for quality control of precision machinery, can accurately measure the size, shape, and positional accuracy of workpieces. However, traditional CMM operations have several problems. Firstly, when placing the machinery to be inspected in the inspection area, the limited distance between the machine and the placement location makes manual handling inconvenient. Furthermore, impurities and oil from the workers' hands can easily contaminate the surface of the precision machinery during operation, affecting not only its appearance but also potentially interfering with the accuracy of the inspection results, leading to misjudgments.
[0003] The inventors believe that the following defects often exist: the distance between the machine to be inspected and the inspection machine is too short, making it inconvenient for the staff to remove the machine from the inspection area, or the staff's palms have a lot of impurities. Using the palms to place the machine into the inspection area of the inspection machine may cause the machine to be inspected to be contaminated by impurities, which may affect the staff's work or the inspection results. Therefore, in order to solve the above problems, a high-precision three-coordinate inspection device for precision machinery is proposed. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the close proximity between the machine to be inspected and the inspection machine, or the presence of impurities on the worker's hands, which may contaminate the machine and affect the worker's work or the inspection results. Therefore, this invention proposes a high-precision three-coordinate measuring machine for precision machinery.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision three-coordinate measuring machine for precision machinery, comprising an operating table and a measuring machine. One side of the operating table is fixedly connected to the measuring machine. The upper surface of the operating table is provided with a pushing device, which includes a placement plate. The placement plate is fixedly connected to the upper surface of the operating table. A groove is formed on the surface of the placement plate. A pushing plate is slidably connected to the surface of the groove of the placement plate. A connecting block is fixedly connected to one side of the pushing plate. A sliding rod is fixedly connected to one side of the connecting block. The arc surface of the sliding rod is slidably connected to the placement plate. A support plate is fixedly connected to one side of the placement plate. A round rod is fixedly connected to the surface of the support plate. An operating plate is slidably connected to the arc surface of the round rod. An insertion rod is fixedly connected to the lower surface of the operating plate. An insertion hole is formed on the surface of the pushing plate.
[0006] The effect achieved by the above-mentioned components is as follows: by setting up the pushing device, it is convenient to push the machinery to be tested into the testing area of the testing machine, avoiding the situation where the distance between the machinery to be tested and the testing machine is too close, making it inconvenient for the staff to remove the machinery from the testing area, or where the staff's palms have a lot of impurities, and using their palms to put the machinery into the testing area of the testing machine may cause the machinery to be tested to be contaminated with impurities, which may affect the work of the staff or affect the testing results, thus improving the practicality of the device.
[0007] Preferably, one end of the round rod is fixedly connected to a limiting plate, and the size of the insertion rod is adapted to the size of the insertion hole of the push plate.
[0008] The effect achieved by the above components is that the limiting plate restricts the maximum sliding distance of the operating plate on the arc surface of the rod, thus preventing the operating plate from detaching from the arc surface of the rod due to excessive pulling force when the operator pulls it.
[0009] Preferably, a first spring is fitted onto the arc surface of the round rod, and the two ends of the first spring are fixedly connected to the operating plate and the support plate, respectively.
[0010] The effect achieved by the above components is to improve the stability of the insertion rod when it limits the push plate, thereby improving the stability during mechanical placement.
[0011] Preferably, an elastic ring is fixedly connected to the surface of the control panel, and the elastic ring is slidably connected to the arc surface of the round rod.
[0012] The effect achieved by the above components is that the elasticity of the elastic ring wraps around the arc surface of the round rod, thereby reducing the sliding speed of the control panel on the arc surface of the round rod, reducing the impact of external shaking on the control panel, and playing a damping role.
[0013] Preferably, a second spring is fitted onto the arc surface of the sliding rod, and the two ends of the second spring are fixedly connected to the connecting block and the placement plate, respectively.
[0014] The effect achieved by the above components is that the second spring automatically removes the tested machinery from the testing area of the testing machine, thereby reducing the number of steps required for the operator to operate the device and improving the operator's work efficiency.
[0015] Preferably, an adjustment device is provided on one side of the operating table. The adjustment device includes a fixing block, which is fixedly connected to one side of the operating table. An operating rod is slidably connected inside the fixing block. The arc surface of the operating rod is slidably connected to the operating table. One end of the operating rod is fixedly connected to a placement plate. An L-shaped plate is fixedly connected to one side of the fixing block. A drive rod is threaded into the L-shaped plate. One end of the drive rod is rotatably connected to a locking block. The arc surface of the operating rod has several locking grooves. The locking block is slidably connected to the surface of the locking grooves of the operating rod.
[0016] The effect achieved by the above components is that by setting up an adjustment device, the height of the placement plate can be adjusted so that if the machinery to be inspected is too large, it will be difficult to place the large machinery between the placement plate and the inspection machine, which would make it difficult to complete the mechanical inspection, thus improving the applicability of the device.
[0017] Preferably, a positioning rod is fixedly connected to the side of the snap-fit block near the drive rod, and the arc surface of the positioning rod is slidably connected to the L-shaped plate.
[0018] The effect achieved by the above components is that the positioning rod restricts the locking block from rotating with the drive rod, so as to provide stable and accurate guidance for the locking block.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] 1. In this utility model, by setting up a pushing device, the effect of conveniently pushing the machinery to be tested into the testing area of the testing machine is achieved. This avoids situations where the distance between the machinery to be tested and the testing machine is too close, making it inconvenient for the staff to remove the machinery from the testing area, or where the staff's palms have a lot of impurities. Using the palms to put the machinery into the testing area of the testing machine may cause the machinery to be tested to be contaminated by impurities, which may affect the work of the staff or the testing results. This improves the practicality of the device.
[0021] 2. In this utility model, by setting an adjustment device, the height of the placement plate can be adjusted so that if the machinery to be tested is too large, it is difficult to place the large machinery between the placement plate and the testing machine, which would make it difficult to complete the mechanical testing. This improves the applicability of the device. Attached Figure Description

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a high-precision three-coordinate measuring machine for precision machinery, including an operating table 1 and a measuring machine 2. One side of the operating table 1 is fixedly connected to the measuring machine 2. The upper surface of the operating table 1 is provided with a pushing device 3. By setting the pushing device 3, the machinery to be inspected can be conveniently pushed into the inspection area of the measuring machine 2. This avoids situations where the distance between the machinery to be inspected and the measuring machine 2 is too close, making it inconvenient for the operator to remove the machinery from the inspection area, or where the operator's palms have a lot of impurities. Using the palms to put the machinery into the inspection area of the measuring machine 2 may contaminate the machinery to be inspected, affecting the operator's work or the inspection results. This improves the practicality of the device. One side of the operating table 1 is provided with an adjustment device 4. By setting the adjustment device 4, the height of the placement plate 301 can be adjusted so that the machinery to be inspected is not too large. Larger machinery is difficult to place between the placement plate 301 and the measuring machine 2, making it difficult to complete the mechanical inspection. This improves the applicability of the device.
[0029] The specific settings and functions of the pushing device 3 and the adjusting device 4 will be explained in detail below.
[0030] Reference Figure 2 , Figure 3 and Figure 4As shown, in this embodiment: the pushing device 3 includes a placement plate 301, which is fixedly connected to the upper surface of the operating table 1. A groove is formed on the surface of the placement plate 301, and a pushing plate 302 is slidably connected to the surface of the groove. A connecting block 303 is fixedly connected to one side of the pushing plate 302, and a sliding rod 304 is fixedly connected to one side of the connecting block 303. The arc surface of the sliding rod 304 is slidably connected to the placement plate 301. A support plate 305 is fixedly connected to one side of the placement plate 301. The surface of the support plate 305... A round rod 306 is fixedly connected to the surface of the device. An operating plate 307 is slidably connected to the arc surface of the round rod 306. A plug rod 308 is fixedly connected to the lower surface of the operating plate 307. A insertion hole is provided on the surface of the push plate 302. A limit plate 309 is fixedly connected to one end of the round rod 306. The size of the plug rod 308 is adapted to the size of the insertion hole of the push plate 302. The limit plate 309 achieves the effect of limiting the maximum sliding distance of the operating plate 307 on the arc surface of the round rod 306, thus preventing the operator from pulling the operating plate 307 with excessive force. This causes the operating plate 307 to detach from the arc surface of the round rod 306. A first spring 310 is fitted onto the arc surface of the round rod 306. The two ends of the first spring 310 are fixedly connected to the operating plate 307 and the support plate 305, respectively, improving the stability of the insertion rod 308 when it limits the push-in plate 302, thereby improving the stability during mechanical placement. An elastic ring 311 is fixedly connected to the surface of the operating plate 307. The elastic ring 311 is slidably connected to the arc surface of the round rod 306, and the elastic force of the elastic ring 311 wraps around the arc surface of the round rod 306. The curved surface reduces the sliding speed of the operating plate 307 on the curved surface of the round rod 306, reducing the impact of external shaking on the operating plate 307 and providing a damping effect. The curved surface of the sliding rod 304 is fitted with a second spring 312, the two ends of which are fixedly connected to the connecting block 303 and the placement plate 301, respectively. The second spring 312 automatically removes the tested machinery from the testing area of the testing machine 2, thereby reducing the number of steps required for the operator to operate the device and improving the operator's work efficiency.
[0031] Reference Figure 5As shown, specifically, the adjusting device 4 includes a fixing block 41, which is fixedly connected to one side of the operating table 1. An operating rod 42 is slidably connected inside the fixing block 41. The arc surface of the operating rod 42 is slidably connected to the operating table 1. One end of the operating rod 42 is fixedly connected to the placement plate 301. An L-shaped plate 43 is fixedly connected to one side of the fixing block 41. A driving rod 44 is threaded into the L-shaped plate 43. A locking block 45 is rotatably connected to one end of the driving rod 44. Several locking grooves are opened on the arc surface of the operating rod 42. The locking block 45 is slidably connected to the surface of the locking groove of the operating rod 42. A positioning rod 46 is fixedly connected to the side of the locking block 45 near the driving rod 44. The arc surface of the positioning rod 46 is slidably connected to the L-shaped plate 43. The positioning rod 46 achieves the effect of restricting the locking block 45 from rotating with the driving rod 44, so as to provide stable and accurate guidance for the locking block 45.
[0032] Working principle: When the machine needs to be pushed into the testing area of the testing machine 2, the operator pulls the operating plate 307. The operating plate 307 overcomes the elastic force of the first spring 310 and slides on the arc surface of the round rod 306, driving the insertion rod 308 to move and release the obstruction to the push plate 302. At this time, the push plate 302 is pushed so that it slides along the groove of the placement plate 301, sending the machine into the testing area. The operating plate 307 is released, the first spring 310 releases its rebound force, driving the operating plate 307 and the insertion rod 308 to reset, so that the insertion rod 308 is reinserted into the insertion hole of the push plate 302, and the push plate 302 is firmly fixed. When the test is completed, the insertion rod 308 is released. After the push plate 302 is limited, the second spring 312 on the arc surface of the sliding rod 304 releases its elastic force, pushing the connecting block 303 and the push plate 302 to slide backward automatically, taking the detected machinery away from the detection area, reducing manual operation steps and improving work efficiency. During the sliding process of the operating plate 307, the elastic ring 311 on its surface contacts the round rod 306, using elastic force to wrap the round rod 306, slowing down the sliding speed of the operating plate 307, reducing the impact of external shaking, and playing a damping role; while the limiting plate 309 limits the sliding distance of the operating plate 307, preventing it from detaching from the round rod 306, ensuring that the entire push-in and push-out process is stable and reliable.
[0033] When the position of the placement plate 301 needs to be adjusted, the operator rotates the drive rod 44, which moves threadedly within the L-shaped plate 43. Since one end of the drive rod 44 is rotatably connected to the locking block 45, the locking block 45 moves along with the drive rod 44. At the same time, the positioning rod 46 fixed on the locking block 45 slides within the L-shaped plate 43, restricting the locking block 45 from rotating with the drive rod 44. This ensures that the locking block 45 slides smoothly along a fixed direction, disengaging it from the current locking slot of the operating rod 42 and releasing the lock on the operating rod 42. At this time, the operating rod 42 can slide freely within the fixed block 41 and the operating table 1. The operator pushes the operating rod 42, moving the placement plate 301 to the target position. After reaching the target position, the operator rotates the drive rod 44 in the opposite direction, causing the locking block 45 to move in the opposite direction and engage with the corresponding locking slot of the operating rod 42. The operator then relocks the operating rod 42, thus firmly fixing the placement plate 301 in the adjusted position, achieving precise adjustment and reliable positioning of the placement plate 301.
