Description

Technical Field

[0001] The invention relates to the technical field of measuring equipment, in particular to processing equipment based on the combination of a gantry three-coordinate measuring instrument and an articulated arm measuring instrument. Background Art

[0002] The three-coordinate measuring machine is a high-precision measuring device that realizes three-axis movement through mobile components. It uses a high-performance data acquisition system and can complete complex geometric shape measurement tasks in a fixed space. Its internal structure consists of three sets of mutually perpendicular transmission systems, which can guide the data acquisition system to move along any path in three-dimensional space, and finally accurately depict and calculate the specific coordinates of the workpiece through the terminal processing computer. Therefore, the three-coordinate measuring machine is widely used in machinery manufacturing, electronic products, instrumentation, plastic molds and other industries. As an efficient measurement method, the three-coordinate measuring machine can replace a variety of traditional surface measurement tools and expensive combination gauges, and become one of the most effective ways to measure and obtain dimensional data.

[0003] For example, the existing Chinese patent document CN202410752095.6 discloses a gantry three-dimensional coordinate measuring machine, including a measuring platform and a gantry measuring seat arranged on the measuring platform, the gantry measuring seat is provided with a movable seat, and the movable seat is provided with a telescopic measuring arm, the telescopic measuring arm is provided with a measuring head, the movable seat is provided with a cleaning component for cleaning the measuring head, and a cavity is opened on the measuring platform and two movable plates are slidably installed in the cavity; the gantry three-dimensional coordinate measuring machine, the electric push rod drives the adjustment plate to move, the movement of the adjustment plate drives the connecting sleeve to follow the movement on the prism, so that the first clamping gear is meshed with the second clamping gear, and then the motor drives the rotating rod and the prism to rotate, the rotation of the prism drives the connecting sleeve to rotate, and drives the bidirectional screw to rotate under the transmission action of the first clamping gear and the second clamping gear, the rotation of the bidirectional screw drives the movable plates on both sides to approach each other, and then drives the two clamping plates to approach each other to clamp and fix the measuring piece, so as to ensure the stability of the measuring piece during measurement, and avoid the shaking of the measuring piece during measurement and interfere with the measurement result;

[0004] In the above scheme, the equipment must rely on the cooperation between the clutch assembly and the clamping gear during the clamping action. However, both the clutch assembly and the clamping gear will inevitably be damaged during long-term operation due to the collision and friction between the gear sets, resulting in the falling of some debris particles. Over time, these fallen debris particles will accumulate inside the gear set. The debris will not only adhere to the surface of the gear, but will also further affect the clamping accuracy of the clamping action, thereby seriously affecting the service life and efficiency of the gear. The continued existence of this situation will undoubtedly increase the cost of equipment use and bring additional burdens to maintenance and maintenance. Summary of the invention

The three-coordinate measuring machine 1 and the articulated arm measuring machine 3 are both existing equipment, wherein the model of the articulated arm measuring machine 3 is CNA7-SCAN, and the model of the three-coordinate measuring machine 1 is HC-L2; it also includes: a transfer unit 4 installed on the extension plate 2 and the three-coordinate measuring machine 1, through which the gantry three-coordinate and articulated arm measuring instrument can be combined, and the high-precision measurement characteristics of the three-coordinate measuring machine 1 are combined with the adaptability of the articulated arm measuring instrument to complex-shaped workpieces. When facing a workpiece with a complex shape and extremely high precision requirements, the flexibility of the articulated arm measuring machine 3 can be used to perform preliminary measurement and positioning of special parts and details of the workpiece, and then the high precision of the gantry three-coordinate measuring machine 1 can be used to perform precise measurement and data correction, so as to more accurately obtain the size and shape information of the workpiece, and effectively reduce the measurement error.

[0033] A moving seat 5 is installed on the top of the transfer unit 4, a measuring platform 6 is fixed on the top of the moving seat 5, four groups of clamping units 7 are evenly distributed on the measuring platform 6, a large gear ring 8 is rotatably connected to the top of the moving seat 5, and the large gear ring 8 is transmission-connected to the bottom of the clamping unit 7, and a horizontal rack 9 is provided on the top of the three-dimensional coordinate measuring machine 1 and the top of the extension plate 2; an annular tube 10 is arranged just above the large gear ring 8, a plurality of blowing pipes 11 are evenly distributed on the bottom of the annular tube 10, a plurality of Z-shaped plates are fixed on the top of the annular tube 10, and the annular tube 10 is fixedly connected to the moving seat 5 through the Z-shaped plate, and four groups of air supply units 12 are transmission-connected on the outer side of the large gear ring 8, and the designed annular tube 10, a plurality of blowing pipes 11 and an air supply unit 12 cooperate with each other, so that the residual particles falling from the gear and the large gear ring 8 can be cleaned synchronously while clamping the measuring piece, so as to avoid the accumulation of the fallen residual particles inside the gear group, thereby seriously affecting the service life and use efficiency of the gear.

[0034] For further information, see Figure 2 and Figure 5, the transfer unit 4 includes a servo motor 13, the servo motor 13 is fixed to one end of the top of the extension plate 2, the output end of the servo motor 13 is fixedly connected to a ball screw 14 through a coupling, the ball screw 14 is installed on the extension plate 2 and the three-dimensional measuring machine 1 through a bearing seat, a first moving block 15 is fixed at the top center position of the moving seat 5, the ball screw 14 is transmission-connected to the first moving block 15 through a ball nut, two guide rails 16 are symmetrically installed on the top of the extension plate 2, a first slider 17 adapted to the guide rail 16 is fixed to the bottom of the moving seat 5, a lubrication assembly 18 is installed at the bottom of the moving seat 5, and the bottom end of the clamping unit 7 is transmission-connected to the lubrication assembly 18;

[0035] Before measurement, the moving seat 5 is located at the rightmost side of the extension plate 2. At this time, the workpiece to be measured is placed on the measuring platform 6, and then the servo motor 13 is started to rotate. The servo motor 13 drives the ball screw 14 to rotate, and the ball screw 14 drives the first moving block 15 to move to the left, thereby driving the moving seat 5 to move to the left. In the process of moving to the center position of the extension plate 2, the clamping unit 7 just triggers the clamping action through the horizontal rack 9, thereby clamping and fixing the workpiece, and then the articulated arm measuring machine 3 is used for preliminary measurement and positioning. After the measurement is completed, the servo motor 13 is started again to continue to drive the moving seat 5 to move to the left. In the process of moving to the center position of the three-dimensional coordinate measuring machine 1, the clamping unit 7 just triggers the clamping action through the horizontal rack 9 again, thereby clamping and fixing the workpiece, and finally, with the help of the high precision of the gantry three-dimensional coordinate measuring machine 1, accurate measurement and data correction are performed, so as to more accurately obtain the size and shape information of the workpiece and effectively reduce the measurement error.

[0036] For further information, see Figure 6The clamping unit 7 includes a second slider 19, a groove 20 is formed on the top of the second slider 19, an elastic member 21 is fixed inside the groove 20, a first U-shaped connecting plate 22 is fixed on the top of the elastic member 21, a clamping plate 23 is fixed on one side of the first U-shaped connecting plate 22, a first connecting rod 24 is rotatably connected to the top of the second slider 19, a first connecting rod 24 is rotatably connected to the end away from the second slider 19, a first crank 25 is rotatably connected to the end of the first crank 25 away from the first connecting rod 24, a first rotating shaft 26 is fixed to the end of the first crank 25 away from the first connecting rod 24, the first rotating shaft 26 is rotatably connected to the moving seat 5 through a bearing, and the top of the measuring platform 6 A slide groove 27 adapted to the second slider 19 is provided, a first gear 28 is fixedly sleeved on the outer side of the first rotating shaft 26, the first gear 28 is meshingly connected with the large gear ring 8, the first gear 28 is provided with four groups, a first pulley 29 is fixed on the top of one group of the first gears 28, the first pulley 29 is connected to the second pulley 30 through a synchronous belt transmission, a second rotating shaft 31 is fixed in the middle hole of the second pulley 30, the second rotating shaft 31 is rotatably connected to the moving seat 5 through a bearing, a second gear 32 is also fixedly sleeved on the outer side of the second rotating shaft 31, and the bottom end of the first rotating shaft 26 is transmission-connected to the lubrication assembly 18.

[0037] Among them, see Figure 7 The elastic member 21 includes a first slide bar 33 fixed in the groove 20, a first limit seat 34 is slidably sleeved on the outer side of the first slide bar 33, the first limit seat 34 is slidably connected to the groove 20, a spring 35 is fixed at one end of the first limit seat 34, the spring 35 is arranged around the outer side of the first slide bar 33, and one end of the spring 35 away from the first limit seat 34 is fixed to the inner wall of the groove 20, and the top of the first limit seat 34 is fixedly connected to the first U-shaped connecting plate 22;

[0038] The principle of the clamping unit 7 driving the clamping plate 23 to move is as follows: the second gear 32 is driven to move by the movement of the moving seat 5, so that the second gear 32 and the horizontal rack 9 are meshed, the second gear 32 rotates and drives the second shaft 31 to rotate, the second shaft 31 drives the second pulley 30 to rotate, the second pulley 30 drives the first pulley 29 to rotate, the first pulley 29 drives the first gear 28 to rotate, the first gear 28 drives the first shaft 26 to rotate, the first shaft 26 drives the first crank 25 to rotate, and the moving seat 5 moves to the three-dimensional coordinate measuring machine. During the process of moving the second slider 19 to the center position of the measuring platform 6, the second gear 32 rotates half a circle, so that the first connecting rod 24 drives the second slider 19 to slide in the slide groove 27 to the limit position close to the center of the measuring platform 6, and then the clamping plate 23 contacts the surface of the workpiece and is pressed to drive the clamping plate 23 to continue sliding in the groove 20, thereby driving the first limit seat 34 to push the spring 35 to move, thereby flexibly changing the position of each clamping plate 23, so that the size of the space clamped by the four clamping plates 23 can be adjusted in a non-proportional manner to adapt to the clamping of workpieces of different shapes.

[0039] For further information, see Fig.11 The number of teeth on the horizontal rack 9 is twice the number of teeth on the second gear 32. The horizontal rack 9 is meshed with the second gear 32. When the second gear 32 and the horizontal rack 9 are meshed, the second gear 32 is driven to rotate, so that before moving to the center position of the three-dimensional coordinate measuring machine 1, the second gear 32 just rotates half a circle, so that the clamping unit 7 can be automatically triggered to work, which is convenient for fast clamping of the workpiece and reduces the clamping time. In addition, the number of teeth on the horizontal rack 9 is more than the number of teeth on the second gear 32, so that the horizontal rack 9 and the second gear 32 can always be kept in mesh after clamping, so that the second gear 32 has a clamping effect, preventing the spring 35 from resetting and generating an elastic force in the opposite direction to push the first slider 17 to produce relative slip.

[0040] Example 2: Please refer to Figure 8 and Fig. 9 This embodiment further explains the first embodiment, and the difference lies in that the large gear ring 8 and the first gear 28 are optimized.

[0041] Specifically, the air supply unit 12 includes a third gear 36, the third gear 36 is meshed with the large gear ring 8, a third pulley 37 is fixed on the top of the third gear 36, the third gear 36 and the third pulley 37 are jointly fixedly sleeved with a third rotating shaft 38, the third rotating shaft 38 is rotatably connected to the moving seat 5 through a bearing, the third pulley 37 is connected to a fourth pulley 39 through a synchronous belt transmission, a fourth rotating shaft 40 is fixedly sleeved in the middle hole of the fourth pulley 39, the fourth rotating shaft 40 is rotatably connected to the moving seat 5 through a bearing, a second crank 41 is fixed on the top of the fourth rotating shaft 40, a first sliding pin 42 is fixed on one end of the top of the second crank 41, and a first slot plate 43 is slidably connected to the outer side of the first sliding pin 42 A first movable rod 44 is fixed to one side of the first groove plate 43, a sealing cylinder 45 is slidably sleeved on the outer side of the first movable rod 44, a piston block 46 is slidably connected inside the sealing cylinder 45, an end of the first movable rod 44 away from the first groove plate 43 is fixedly connected to the piston block 46, an end of the sealing cylinder 45 away from the second crank 41 is fixedly connected to an air inlet pipe 47 through a one-way valve, an air outlet pipe 48 is fixedly fixed to the top of the sealing cylinder 45 through a one-way valve, an end of the air outlet pipe 48 away from the sealing cylinder 45 is fixedly connected to the annular tube 10, a fixed hoop 49 is provided on the outer side of the sealing cylinder 45, a second U-shaped connecting plate 50 is fixed to the bottom of the fixed hoop 49, and the bottom of the second U-shaped connecting plate 50 is fixedly connected to the movable seat 5;

[0042] At the same time, a connecting pipe 62 is fixedly connected to the annular tube 10, and one end of the connecting pipe 62 away from the annular tube 10 passes through the measuring platform 6, and is fixedly connected to an air supply pipe 63, and a plurality of air nozzles 64 are evenly distributed on one side of the air supply pipe 63, so that while cleaning the large gear ring 8, gas can also be blown out to clean the particles on the surface of the measuring platform 6.

[0043] Specifically, when the first gear 28 rotates half a circle, it will also synchronously drive the large gear ring 8 to rotate, and the large gear ring 8 will drive the third gear 36 to rotate. The third gear 36 rotates half a circle, thereby driving the second crank 41 to rotate half a circle through the transmission effect of the third pulley 37, the third shaft 38, the fourth pulley 39, and the fourth shaft 40. The second crank 41 drives the first sliding pin 42 to slide in the first groove plate 43, so that the first groove plate 43 can move horizontally, thereby pushing the piston block 46 to move in the sealing cylinder 45, sucking the external air into the sealing cylinder 45. 5, in the process of releasing the clamping effect, the second crank 41 is reversed, so that the air stored in the sealing tube 45 is discharged from the air outlet pipe 48 into the annular tube 10, and finally blown out from the blowing pipe 11 at the bottom of the annular tube 10 and blown to the position of the large gear ring 8 and the first gear 28, blowing away the particles between the tooth grooves of the two. In this way, while clamping the measuring piece, the residual particles falling on the gear and the large gear ring 8 can be cleaned synchronously, avoiding the accumulation of the fallen residual particles inside the gear set, thereby seriously affecting the service life and use efficiency of the gear.
