[0019] Embodiment 1: When measuring shaft workpieces, the existing image measuring instrument needs to use a shell whose inner side surface is the same as the shape of the shaft workpiece to fix the shaft workpiece. However, because the sizes and radii of each part of different shaft workpieces are not equal, one shell can usually only be used for one shaft workpiece that needs to be measured. When the staff needs to measure multiple shaft workpieces, multiple shells of different shapes need to be prepared, which makes the existing image measuring device inconvenient to use.

The upper side of the electric rotating shaft 51 is fixedly connected with the multi-stage electric push rod 6 electrically connected to the control terminal through a bracket. The telescopic end of the multi-stage electric push rod 6 is fixedly connected with the fixed frame 7. The lower side of the fixed frame 7 does not contact the upper side of the movable workbench 4. It is used to control the contact position of the piston rod 8 and the shaft workpiece, so that the contact position of the piston rod 8 and the shaft workpiece is closer to the axis of the shaft workpiece to enhance the fixing effect of the piston rod 8 on the shaft workpiece. A cavity is provided in the fixed frame 7, and the cavity is connected to the existing air pump. The air pump is electrically connected to the control terminal. The opposite sides of the two fixed frames 7 are limited and slidably connected. A plurality of piston rods 8 are evenly distributed, and the piston rods 8 are located in the cavities of adjacent fixing frames 7, so that the gas can push the adjacent piston rods 8 out of the outer surface of the fixing frames 7. A first elastic member 9 is fixedly connected between the piston rods 8 and the fixing frames 7, and the first elastic member 9 is a spring. An optical camera 10 electrically connected to the control terminal is installed on the upper side of the fixing platform 3. A first electric push rod 11 electrically connected to the control terminal is fixedly connected in the fixing frame 7, and a shielding plate 12 is fixedly connected to the telescopic end of the first electric push rod 11. The shielding plate 12 is fitted with the inner surface of the cavity of the adjacent fixing frame 7 to prevent the gas from pushing the adjacent piston rods 8 out. Two symmetrically distributed holding racks 13 are fixedly connected to the upper side of the fixing platform 3, and a detachable sliding connection is evenly distributed in the holding rack 13. Several auxiliary parts 14 are arranged on the machine 1, and the auxiliary parts 14 include auxiliary measuring components required for optical image measuring instruments such as prisms.

[0021] See also Figure 10-12 The shock absorbing mechanism includes two groups of hydraulic cylinders 20 symmetrically distributed front and back, each group includes evenly distributed hydraulic cylinders 20, and the number of hydraulic cylinders 20 in each group of hydraulic cylinders 20 is not less than 4. In this embodiment, four hydraulic cylinders 20 in each group are taken as an example, and the hydraulic cylinders 20 are fixedly connected to the lower part of the frame 1. The frame 1 is slidably connected with an electric wheel 21 electrically connected to the control terminal near the adjacent hydraulic cylinder 20. The electric wheel 21 is used to drive the frame 1 to move. A first pushing member 22 is fixedly connected to the upper part of the electric wheel 21. The first pushing member 22 is slidably connected to the adjacent hydraulic cylinder 20. The upper part of the first pushing member 22 is located in the adjacent hydraulic cylinder 20. The upper side of the first pushing member 22 is rotatably connected to the second pushing member 23. The second pushing member 23 is provided with two groups of circular through holes evenly distributed in the circumferential direction, each group includes two symmetrically distributed circular through holes, and the first pushing member 22 is provided with two symmetrically distributed fan-shaped through holes. The fan-shaped through holes are connected to the two adjacent The circular through holes are connected and matched, and a one-way valve 231 is installed in one group of the circular through holes. In the initial state, the two fan-shaped through holes are only connected to the circular through holes on which the one-way valve 231 is installed. The one-way valve 231 can only allow the hydraulic oil on its lower side to move through itself to its upper side. A second elastic member 24 is installed between the second push member 23 and the adjacent hydraulic cylinder 20. The second elastic member 24 is a spring. In the initial state, the second elastic member 24 is in a compressed state under the combined action of the gravity of the frame 1 and the supporting force of the ground on the adjacent electric wheel 21. The upper side spline of the second push member 23 is connected with a rotating cylinder 25. The rotating cylinder 25 is used to drive the second push member 23 to rotate, thereby changing the connection state between the circular through holes on the second push member 23 and the fan-shaped through holes on the adjacent first push member 22. The rotating cylinder 25 is rotatably connected to the frame 1, and the rotating cylinder 25 is rotatably connected to the adjacent hydraulic cylinder 20. A detection component for detecting obstacles is provided on the outer side of the hydraulic cylinder 20.
[0022] See also Figure 10-13The detection component includes an elastic telescopic rod 26 fixed to the outer side of the adjacent hydraulic cylinder 20, and the telescopic end of the elastic telescopic rod 26 is slidably connected to the detection rod 27, and there is a damping between the two, which is used to slow down the reset speed of the detection rod 27. The elastic telescopic rod 26 is used to push the detection rod 27 to reset. The detection rod 27 is fixedly connected to a rack 29. The frame 1 is fixedly connected to a first extrusion platform 30 near the adjacent rack 29. The right part of the first extrusion platform 30 is provided with an inclined surface. The first extrusion platform 30 squeezes the adjacent rack 29 through the inclined surface of its right part, so that the rack 29 is When moving to the right, it moves upward synchronously. The frame 1 is rotatably connected to a transmission rod 31 near the adjacent hydraulic cylinder 20. Gears are fixedly connected to the upper and lower sides of the transmission rod 31. The transmission rod 31 is transmitted to the adjacent rack 29 through the gear on the lower side. The rotating cylinder 25 is fixedly connected to a gear that meshes with the gear on the upper side of the transmission rod 31. The left part of the electric wheel 21 is fixedly connected to a second extrusion platform 32. The left part of the second extrusion platform 32 is provided with an inclined surface. When moving downward, the second extrusion platform 32 squeezes the adjacent detection rod 27 through the inclined surface, so that the adjacent detection rod 27 moves to the right.
[0023] When the staff needs to use this device to measure the size of the workpiece, when measuring an ordinary workpiece, the staff first places the workpiece on the upper side of the mobile workbench 4, and then starts the two multi-stage electric push rods 6 through the control terminal. The telescopic ends of the multi-stage electric push rods 6 drive the fixed frame 7 and other components to extend toward the workpiece, and the two fixed frames 7 clamp the workpiece together to provide a stable observation environment. Then the staff starts the optical camera 10 through the control terminal, and the staff controls the mobile workbench 4 through the control terminal to drive the workpiece to move in the front and back and left and right directions, and establishes a corresponding coordinate system through the control terminal. Then the staff calculates the size of the workpiece through the coordinate system.
[0024] When the staff needs to measure the shaft workpiece, the staff first grasps the two ends of the shaft workpiece with their hands, and then the staff takes the shaft workpiece to the upper side of the movable workbench 4, and ensures that the lower side of the shaft workpiece is in close contact with the movable workbench 4, and the two ends of the axis of the shaft workpiece are respectively facing the front and rear sides of the movable workbench 4, and then the staff controls the two multi-stage electric push rods 6 through the control terminal, so that the telescopic ends of the two multi-stage electric push rods 6 respectively drive the adjacent fixed frames 7 to move to the two sides of the shaft parts, and then the staff controls the first electric push rod 11 through the control terminal, and the telescopic end of the first electric push rod 11 drives the cover The baffle plate 12 moves upward, and as the baffle plate 12 moves from bottom to top, the position of the piston rod 8 on the lower side of the baffle plate 12 is connected to the cavity in the fixing frame 7 again. When the lower side of the baffle plate 12 moves to the plane where the axis of the shaft workpiece is located, the staff closes the first electric push rod 11 through the control terminal, and then the staff introduces a certain amount of air into the fixing frame 7 through the air pump. The piston rod 8 at the position connected to the cavity in the fixing frame 7 is pushed outward by the gas, and the adjacent first elastic member 9 is compressed and stored until the piston rod 8 contacts the shaft workpiece. At this time, the lower side of the shaft workpiece is squeezed and limited by the adjacent piston rod 8 (such as Figure 7 As shown), it will not roll at will, which is convenient for the staff to measure the shaft workpiece through the control terminal, avoiding relative movement between the mobile workbench 4 and the shaft workpiece during the test, resulting in deviation in the measurement result. When the measurement is completed, the staff draws out the gas in the two fixing frames 7 through the control terminal, and the piston rod 8 is reset under the action of the adjacent first elastic member 9. The staff controls the two multi-stage electric push rods 6 and the two first electric push rods 11 through the control terminal to drive the adjacent parts to reset.
[0025] During the process of clamping the shaft workpieces by the two fixed frames 7, the staff controls the upward movement distance of the baffle plate 12 and the extension amount of the piston rod 8 in the fixed frame 7, so as to clamp shaft workpieces of various sizes, and the piston rod 8 in the same plane can be extended to different distances, thereby ensuring that the piston rod 8 can adapt to various special-shaped shaft parts, ensuring the clamping effect of various special-shaped parts, and then assisting the mobile workbench 4 and the mobile workbench 4 to better measure the workpiece.
[0026] When the staff needs to use auxiliary measuring tools such as a prism, the staff controls the electric shaft 51 to rotate 180 degrees through the control terminal, and the electric shaft 51 drives the multi-stage electric push rod 6 and other components to rotate together. Then the control terminal controls the electric slide rail 5 to work, and the electric slide rail 5 drives the electric slide rail 5, the multi-stage electric push rod 6 and the fixed frame 7 and other components to move back and forth, so that the electromagnet 16 on the fixed frame 7 is aligned with the adjacent electromagnet 16 on the auxiliary component 14 that needs to be used. Then the control terminal controls the telescopic end of the multi-stage electric push rod 6 to drive the fixed frame 7 and other components to extend. When the electromagnet 16 on the fixed frame 7 is aligned with the adjacent electromagnet 16 on the adjacent auxiliary component 14 16 contacts, the control terminal controls the telescopic end of the multi-stage electric push rod 6 to stop moving, and activates the electromagnet 16, the electromagnet 16 attracts the adjacent fixing part 15, at this time the fixing frame 7 drives the adjacent auxiliary part 14 to move together, the staff controls the electric slide rail 5, the electric shaft 51 and the multi-stage electric push rod 6 and other components through the control terminal, pulls the auxiliary part 14 out of the adjacent receiving frame 13, and moves the auxiliary part 14 to the vicinity of the measured workpiece to assist in measuring the workpiece. When the measurement is completed, the staff controls the electric slide rail 5, the electric shaft 51 and the multi-stage electric push rod 6 and other components through the control terminal to drive the auxiliary part 14 to reset and remove the workpiece.
[0027] When the staff needs to move the rack 1 and drag the rack 1 from one laboratory to another, the staff first controls the two electric telescopic frames 17 to retract downward through the control terminal. The two electric telescopic frames 17 drive the fixed platform 3 to slide downward through the flexible connecting plate 18 until the fixed platform 3 moves to the lowest part of the four fixed slide rails 2. The staff closes the two electric telescopic frames 17 through the control terminal. At this time, the fixed platform 3 and the adjacent components are located as a whole in the rack 1, so that the center of gravity in the rack 1 is stable, which facilitates all the electric wheels 21 to drive the rack 1 to move stably. The staff starts all the electric wheels 21 through the control terminal, and all the electric wheels 21 jointly drive the rack 1 and the components thereon to move together. The following takes the movement to the left as an example.
[0028] When the motorized wheel 21 drives the rack 1 to move through the laboratory door, the leftmost detection rod 27 first contacts the door during the movement. At this time, the front and leftmost detection rod 27 and adjacent components are taken as an example: The detection rod 27 is squeezed by the gate bar and moves to the right relative to the first squeezing platform 30, and the detection rod 27 drives the rack 29 to move to the right together. The rack 29 is squeezed by the first squeezing platform 30 and moves upward. The rack 29 drives the detection rod 27 and the telescopic end of the elastic telescopic rod 26 to move upward together. The telescopic end of the elastic telescopic rod 26 retracts and accumulates force until the detection rod 27 moves to the same height as the gate bar. The detection rod 27 is no longer squeezed by the gate bar and slowly resets under the action of the elastic telescopic rod 26 and the damping. In the process of the rack 29 moving to the right, it drives the transmission rod 31 to rotate, and the rotation of the transmission rod 31 drives the rotating cylinder 25 to rotate. The rotating cylinder 25 drives the second pushing member 23 to rotate together through the spline. The member 23 rotates so that the circular through hole on which the one-way valve 231 is not installed is connected to the adjacent fan-shaped through hole on the first pushing member 22, and the hydraulic oil flows normally at this time. That is, at this time, the leftmost electric wheel 21 moves upward normally when squeezed by the door fence during movement, while the electric wheels 21 at other positions cannot move upward because the fan-shaped through hole on the adjacent first pushing member 22 is only connected to the circular through hole on which the one-way valve 231 is installed on the adjacent second pushing member 23. Therefore, when the leftmost second pushing member 23 and the electric wheel 21 are squeezed by the door fence and move upward, the adjacent second elastic member 24 is compressed and stored, and the weight of the frame 1 is mainly supported by the electric wheels 21 at other positions.
[0029] When the leftmost electric wheel 21 passes through the gate, the detection rod 27 first returns to its original position, and the detection rod 27 drives the second pusher 23 to rotate and reset through the rack 29 and adjacent components. The second pusher 23 is reset so that the circular through hole on which the one-way valve 231 is not installed is staggered with the adjacent fan-shaped through hole on the first pusher 22, but at this time, the hydraulic oil can flow in one direction through the one-way valve 231 on the second pusher 23, and will not hinder the second elastic member 24 from driving the second pusher 23 and the first pusher 22 to reset. When the electric wheel 21 and the first pusher 22 are reset, the leftmost electric wheel 21 cooperates with the right electric wheel 21 to support the weight of the frame 1 and adjacent components, so that the middle electric wheel 21 passes through the gate in turn. In the above process, only one electric wheel 21 in each group of electric wheels 21 passes through the gate each time, so as to ensure that the frame 1 is always subjected to sufficient stable support force, and there is no rigid support force between the electric wheel 21 passing through the gate and the frame 1. At this time, the second elastic member 24 reduces the vibration of the frame 1 when passing through the gate through its own elasticity.
[0030] When the staff needs to push the frame 1 to pass the gentle slope, when the frame 1 passes the gentle slope and moves downward, at this time, still taking the frame 1 moving to the left as an example, taking the electric wheel 21 and adjacent components on the leftmost side of the frame 1 as an example, when the electric wheel 21 just protrudes out of the gentle slope, the weight of the frame 1 mainly acts on the six electric wheels 21 on the right. At this time, the electric wheel 21, the second pushing member 23 and the first pushing member 22 extend downward under the action of the adjacent second elastic member 24 until the electric wheel 21 contacts the gentle slope. The electric wheel 21 and the adjacent components provide auxiliary support to the frame 1 through the second elastic member 24. In the process of the electric wheel 21 moving downward, the electric wheel 21 drives the second extrusion platform 32 to move downward together. In the process of the second extrusion platform 32 moving downward, it squeezes the detection rod 27 to the right, so that the detection rod 27 moves a certain distance to the right. In the process of the detection rod 27 moving, the second pushing member 23 is driven by the adjacent components to rotate a certain angle, so that the one-way valve 231 not installed on the second pushing member 23 The circular through hole is connected with the adjacent fan-shaped through hole on the adjacent first pushing member 22, and the connecting area is small. The circular through hole on which the one-way valve 231 is installed on the second pushing member 23 is still in a connecting state with the adjacent fan-shaped through hole. At this time, the hydraulic oil mainly flows upward from the lower side of the first pushing member 22 through the one-way valve 231. When the electric wheel 21 in the middle moves to the gentle slope, the frame 1 loses its stable supporting force and slowly tilts downward. At this time, since the connecting area between the circular through hole without the one-way valve 231 and the adjacent fan-shaped through hole is small, the hydraulic oil on the upper side of the first pushing member 22 cannot flow downward quickly, and the hydraulic oil cannot flow downward from the upper side of the first pushing member 22 through the one-way valve 231. Therefore, the electric wheel 21, the first pushing member 22 and the second pushing member 23 are hindered by the flow rate of the hydraulic oil and can only move slowly upward, providing support to the frame 1 while slowly moving and resetting, delaying the speed at which the frame 1 tilts downward, thereby reducing the shaking of the frame 1 caused by the tilt when passing the gentle slope.
[0031] When the rack 1 moves to the bottom of the gentle slope, the ground first squeezes the leftmost detection rod 27, and the detection rod 27 moves according to the same process as when passing through the gate, so that the leftmost electric wheel 21 moves upward first, and when the middle electric wheel 21 is lifted up by the rack 1 and floats in the air, it moves downward to provide auxiliary supporting force for the rack 1, until the rack 1 slowly moves to a horizontal state, and the six electric wheels 21 on the rear side are reset to provide the main supporting force for the rack 1, and the leftmost electric wheel 21 moves downward and resets, and when the rack 1 moves from the lower side of the gentle slope to the upper side of the gentle slope, it still moves according to the above principle.
[0032] After the staff moves the rack 1 to the corresponding position, the staff activates the two electric telescopic frames 17 through the control terminal to drive the fixed platform 3 to move upward and reset.
[0033] Embodiment 2: In order to further reduce the transmission of vibration between the frame 1 and the fixed platform 3, based on Embodiment 1, refer to Figure 2 and Fig. 9 , also includes a buffer mechanism arranged in the frame 1, the buffer mechanism is used to provide buffering for the fixed table 3 during the movement, the buffer mechanism includes two second electric push rods 33 which are symmetrically distributed front and back and are electrically connected to the control terminal, the telescopic ends of the two second electric push rods 33 are fixedly connected to a fixed plate 34, the fixed plate 34 is fixedly connected to two buffer slide rails 35 which are symmetrically distributed left and right, the buffer slide rail 35 is located at the lower side of the adjacent fixed slide rail 2, and the buffer slide rail 35 is aligned with the adjacent fixed slide rail 2, so as to facilitate the fixed table 3 moving downward, the buffer slide rail 35 is slidably connected to the fixed table 3, and the sliding connection between the buffer slide rail 35 and the fixed table 3 is made of flexible material, so that the buffer slide rail 35 and the flexible connecting plate 18 can cooperate with each other, and reduce the amplitude of vibration transmitted from the frame 1 to the fixed table 3 while clamping the fixed table 3.
[0034] When the staff controls the two electric telescopic frames 17 to retract through the control terminal, the staff will not close the electric telescopic frames 17 until the fixed platform 3 slides to the four buffer slide rails 35 through the four fixed slide rails 2. At this time, the staff will start the two second electric push rods 33 through the control terminal. The telescopic ends of the two second electric push rods 33 extend toward each other and jointly control the adjacent fixed plates 34 to drive the adjacent buffer slide rails 35 to clamp the fixed platform 3, thereby fixing the fixed platform 3. At this time, because the contact between the buffer slide rails 35 and the fixed platform 3 and the flexible connecting plate 18 are all made of flexible materials, the fixed platform 3 can be effectively The frame 1 is isolated from vibrations during movement, preventing the frame 1 from vibrating frequently and slightly during movement to affect the fitting accuracy of parts on the fixed table 3. After moving to the specified position, the staff first controls the two second electric push rods 33 to reset through the control terminal, and then controls the two electric telescopic frames 17 to drive the adjacent parts to reset upward. When the fixed table 3 restores the rigid connection with the adjacent fixed slide rail 2, the fixed slide rail 2 provides a stable supporting force to the fixed table 3, preventing the fixed table 3 from shaking during operation and maintaining the fitting accuracy of parts on the fixed table 3.
