DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0016] See also Figures 1 to 7 , an adjustment device for a three-axis displacement controllable three-coordinate measuring machine based on an orthogonal coordinate system, comprising: a base 4, an X-axis control mechanism arranged on the upper end surface of the base, a Z-axis control mechanism slidably connected to the X-axis control mechanism, a Y-axis control mechanism fixedly connected to the Z-axis control mechanism, and a detection platform fixedly connected to the Y-axis control mechanism; The X-axis control mechanism is used to drive the object on the detection table to move in the X-axis direction, the Y-axis control mechanism is used to drive the object on the detection table to move in the Y-axis direction, and the Z-axis control mechanism is used to drive the object on the detection table 304 to move in the Z-axis direction.

[0017] It should be noted that the main invention point of this scheme is that by setting up separate control mechanisms in the three directions of X-axis, Y-axis and Z-axis, displacement of the detection part in the directions of X-axis, Y-axis and Z-axis can be generated, so that the detection part can be more targeted during actual detection.

[0018] In one embodiment of the present invention, the X-axis control mechanism comprises: a U-shaped first slide rail 1, an X-axis slider 101, a bottom plate 102 and an X-axis driving mechanism; The U-shaped first slide rail 1 is fixedly connected to the upper end surface of the base, and the two ends of the inner wall of the U-shaped first slide rail 1 are symmetrically fixedly connected with first inverted T-shaped mounting members 103; The X-axis sliders 101 are provided with two pairs and are symmetrically slidably connected to the top two sides of the U-shaped first slide rail 1. The bottom end surface of the bottom plate 102 is fixedly connected to the X-axis sliders 101 and the moving parts of the X-axis driving mechanism respectively; the top end surface of the bottom plate 102 is fixedly connected to the bottom end surface of the Z-axis control mechanism; The X-axis driving mechanism is fixedly connected between the first inverted T-shaped mounting members 103 , and the X-axis driving mechanism is used to drive the bottom plate to move along the U-shaped first slide rail 1 .

[0019] It should be noted that the first slide rail includes: a U-shaped frame, slide rails symmetrically arranged on both sides of the top of the U-shaped frame, and both ends of the slide rails are provided with inverted U-shaped limiters; the X-axis slider is slidably connected to the slide rail.

[0020] Among them, a displacement sensor is embedded in the middle position of the base plate, and the displacement sensor is communicatively connected with an external computer. When the base plate moves along the slide rail, the displacement sensor feeds back the initial position signal of the base plate and the position signal during the movement to the computer in real time.

[0021] In one embodiment of the present invention, the X-axis driving mechanism comprises: a first screw rod 104, a first ball nut sleeve 105 and a first hand wheel; The first screw rod 104 is inserted between the first inverted T-shaped mounting pieces 103, a bearing is provided at the contact position between the first screw rod 104 and the first inverted T-shaped mounting piece 103, and one end of the first screw rod 104 is fixedly connected to the first hand wheel; The first ball nut sleeve 105 is screwed onto the first screw rod 104 . A first connecting ring 106 is sleeved onto the first ball nut sleeve 105 . The upper end surface of the first connecting ring 106 is fixedly connected to the bottom end surface of the bottom plate 102 .

[0022] It should be noted that the principle of the X-axis drive mechanism driving the base plate to move relies on the principle of screw rotation to convert rotational motion into linear motion. Specifically, the first hand wheel is used to drive the first screw to rotate, and then the first screw rotates to drive the first rolling nut to move along the first screw, thereby driving the base plate fixedly connected to the first connecting ring to move linearly along the slide rail.

[0023] Among them, the first connecting ring is a rectangular block with a mounting hole in the middle, and the top end face of the rectangular block is bolted to the base plate. The main function of the first connecting ring is to avoid the first ball nut being directly connected to the base plate, which will destroy the strength of the first ball nut and shorten its service life. The first connecting ring can both protect the first ball nut and facilitate connection and disassembly with the base plate.

[0024] In one embodiment of the present invention, the Z-axis control mechanism comprises: a support frame 2, a substrate 201 and a Z-axis driving mechanism; Two second slide rails 202 are fixedly arranged vertically in parallel on the support frame 2, and a Z-axis slider 203 is symmetrically slidably connected to the second slide rails 202.

[0025] It should be noted that the support frame mainly plays a supporting role for the Y-axis control mechanism, and the support frame includes: a support plate and a pair of reinforcement plates; The reinforcing plate is symmetrically fixedly connected to the middle and lower part of the rear end surface of the supporting plate, and the lower ends of the reinforcing plate and the supporting plate are fixedly connected to the bottom plate; the sliding rail is fixedly connected to the front end surface of the supporting plate.

[0026] Among them, a displacement sensor is embedded in the middle position of the base plate, and the displacement sensor is communicatively connected with an external computer. When the base plate moves along the slide rail, the displacement sensor feeds back the initial position signal of the base plate and the position signal during the movement to the computer in real time.

[0027] In one embodiment of the present invention, the Z-axis driving mechanism comprises: a second screw rod 205, a second ball nut sleeve 206 and a second hand wheel; The second screw rod 205 is inserted between the second inverted T-shaped mounting pieces 204 , a bearing is provided at the contact position between the second screw rod 205 and the second inverted T-shaped mounting piece 204 , and one end of the second screw rod 205 is fixedly connected to the second hand wheel 207 ; The second ball nut sleeve 206 is screwed onto the second screw rod 205 . A second connecting ring 207 is sleeved onto the second ball nut sleeve 206 . The outer end surface of the second connecting ring 207 is fixedly connected to the rear end surface of the base plate 201 . The base plate 201 is in a U-shaped structure.

[0028] It should be noted that the working principle of the Z-axis driving mechanism driving the substrate refers to the working process of the aforementioned X-axis driving mechanism and will not be repeated here.

[0029] A displacement sensor is embedded in the middle of the substrate, and the displacement sensor is communicatively connected to an external computer. When the substrate moves along the slide rail, the displacement sensor feeds back the initial position signal of the substrate and the position signal during the movement to the computer in real time.

[0030] In one embodiment of the present invention, the Y-axis control mechanism comprises: a mounting plate 3 and a Y-axis driving mechanism; The rear end surface of the mounting plate 3 is fixedly connected to the front end surface of the base plate 201, and a pair of third slide rails 301 are arranged in parallel on the front end surface of the mounting plate 3; The third slide rail 301 is symmetrically slidably connected with a Y-axis slider 302, and a pair of third inverted T-shaped mounting members 303 are fixedly arranged between the third slide rails 301. The third inverted T-shaped mounting members 303 are respectively located at both ends of the third slide rail 301; The Y-axis driving mechanism is fixedly connected between the third inverted T-shaped mounting members 303; The rear end surface of the detection platform 304 is fixedly connected to the Y-axis slider 302 and the moving part of the Y-axis driving mechanism respectively; The Y-axis driving mechanism is used to drive the detection platform 304 to move along the third slide rail 301 in the Y-axis direction.

[0031] In one embodiment of the present invention, the Y-axis driving mechanism comprises: a third screw rod 305, a third ball nut sleeve 306 and a third hand wheel; The third screw rod 305 is inserted between the third inverted T-shaped mounting pieces 303, a bearing is provided at the contact position between the third screw rod 305 and the third inverted T-shaped mounting piece 303, and one end of the third screw rod 305 is fixedly connected to the third hand wheel; The third ball nut sleeve 306 is screwed onto the third screw rod 305 . A third connecting ring 307 is sleeved onto the third ball nut sleeve 306 . The outer end surface of the third connecting ring 307 is fixedly connected to the rear end surface of the detection platform 304 .

[0032] It should be noted that the working principle of the Y-axis driving mechanism driving the substrate refers to the working process of the aforementioned X-axis or Y-axis driving mechanism and will not be repeated here.

[0033] Among them, a displacement sensor is embedded in the middle position of the detection platform, and the displacement sensor is communicatively connected with an external computer. When the detection platform moves along the slide rail, the displacement sensor feeds back the initial position signal of the detection platform and the position signal during the movement to the computer in real time.

[0034] In addition, in the present solution, the driving mode of the X-axis control mechanism, the Y-axis control mechanism and the Z-axis control mechanism can be driven by a motor, and the motor is connected to an external computer for communication, so that fully automatic detection can be achieved.

[0035] The present invention provides a working method for an adjustment device of a three-axis displacement controllable three-coordinate measuring machine based on an orthogonal coordinate system. When in use, a detection piece is placed in a groove on a detection table, and then a first hand wheel is driven to drive a first screw rod to rotate, thereby driving a bottom plate to move on a first slide rail, thereby achieving movement in the X-axis direction; The second hand wheel is driven to drive the second screw rod to rotate, thereby driving the bottom plate to move on the second slide rail, so as to achieve the movement in the Z-axis direction; The third hand wheel is driven to drive the third screw rod to rotate, thereby driving the bottom plate to move on the third slide rail, so as to achieve the movement in the Y-axis direction; In the above process, the handwheel can be replaced by a motor, and during the entire driving process, the displacement sensor feeds back the real-time position signals of the bottom plate, substrate and detection platform to the computer in real time, so that the displacement distance in the X-axis, Y-axis and Z-axis directions can be accurately controlled by the computer.
