Description

Technical Field

[0001] This invention relates to the field of testing tooling technology, and in particular to a five-axis reference slide. Background Technology

[0002] The five-axis reference slide is the core tooling for motion accuracy testing of the module slide. Its core function is to provide a stable and accurate fixed reference for the Z-axis motion reference plate, ensuring that the reference does not deviate or loosen during the module slide testing process, thereby ensuring the accuracy of the test data.

[0003] In some five-axis reference slides, the Z-axis motion reference plate is fixed with screws. However, this rigid contact can easily scratch the precision detection surface of the reference plate, leading to a decrease in the accuracy of the reference plate, a shortened service life, and the inability to eliminate the slight deformation caused by clamping force, which affects the stability of the reference. At the same time, it is impossible to dynamically adjust the clamping force according to the detection motion of the module slide. During the detection process, the reference plate is prone to slight shaking due to vibration and external force, which leads to an increase in detection error. Summary of the Invention

[0004] The present invention provides a five-axis reference slide, which achieves the dual effects of initial elastic clamping and dynamic reinforcement fixation of the Z-axis motion reference plate through the coordinated cooperation of various components.

[0007] As a further improvement of the present invention: the plurality of push plates and the plurality of transmission plates are all elastically connected by a first spring, and the inner walls of the plurality of sleeves are all fixedly embedded with baffles, the baffles are in contact with the push plates, and the push plates can slide along the inner walls of the sleeves.

[0008] As a further improvement of the present invention: the fixed frame is also provided with an opening and closing adjustment component, which is connected to one side of two of the clamping plates and is used to adjust the distance between the four clamping plates to realize the clamping and disassembly of the Z-axis motion reference plate.

[0009] As a further improvement of the present invention: the opening and closing adjustment component includes a slide groove, an L-shaped slider and a vertical plate. The slide groove is opened on one side of the fixed frame. The L-shaped slider is movably embedded in the inner wall of the slide groove. One end of the L-shaped slider is fixedly connected to the top of the pressure plate and the other end is fixedly connected to the vertical plate. The L-shaped slider can slide along the inner wall of the slide groove, driving the pressure plate to move in a direction closer to or away from the Z-axis motion reference plate.

[0010] As a further improvement of the present invention: the number of the multiple sleeves is four, and the four sleeves are respectively fixedly disposed at the center positions of the four sides of the inner wall of the fixing frame, correspondingly forming four clamping plates.

[0011] As a further improvement of the present invention: the pressurization drive assembly includes two fixed guide rails parallel to the upper side of the lower reference plate, a module slide is movably mounted on the fixed guide rails, the module slide can slide linearly along the fixed guide rails, two base plates are fixedly provided at the bottom of the lower reference plate, a pressurization main cylinder is fixedly provided on one side of each of the two base plates, and a piston plate is movably embedded in the inner wall of each of the two pressurization main cylinders.

[0012] As a further improvement of the present invention: a round rod is fixedly connected to one side of each of the two piston plates, and a horizontal plate is connected to the end of the two round rods away from the piston plates. The horizontal plate is in contact with the module slide. The piston plates can slide along the inner wall of the pressurized main cylinder to compress the sealed gas inside the pressurized main cylinder.

The number of the multiple second flow guiding pipes matches the number of the sleeves. One end of the second flow guiding pipe is connected to the outlet of the three-way connector, and the other end is connected to the inlet of the sleeve, thereby realizing the diversion and transmission of high-pressure gas.

[0014] As a further improvement of the present invention: a five-axis moving platform is provided between the lower reference plate and the upper reference plate, the bottom of the five-axis moving platform being fixedly connected to the lower reference plate and the top being fixedly connected to the upper reference plate.

It utilizes only the detection motion of the module slide itself. The further the module slide pushes, the stronger the clamping force becomes, completely resolving the shortcomings of existing rigid clamping systems that easily scratch the reference plate and cause it to loosen due to constant clamping force. Simultaneously, the elastic clamping structure eliminates mating gaps and localized stresses, preventing minor deformation of the reference plate, improving reference stability, reducing module slide detection errors, and enhancing detection accuracy and efficiency. It is suitable for precision batch testing scenarios in factories, reducing detection errors and improving detection accuracy. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1 - Figure 9 This invention provides a five-axis reference slide, comprising: a lower reference plate 1, an upper reference plate 102, and a Z-axis motion reference plate 103. A mounting slot 2 is provided on one side of the upper reference plate 102, and a fixing frame 201 is provided within the mounting slot 2. An elastic clamping assembly is disposed within the fixing frame 201 to achieve initial elastic clamping and fixing of the Z-axis motion reference plate 103. A pressurizing drive assembly is disposed on the upper side of the lower reference plate 1 and is connected to the elastic clamping assembly via an air passage. It is used to generate high-pressure gas through the movement of the module slide 308, driving the elastic clamping assembly to achieve dynamic reinforcement and fixing of the Z-axis motion reference plate 103. Two flow guiding assemblies are respectively connected to the pressurizing drive assembly and the elastic clamping assembly to realize the transmission of high-pressure gas from the pressurizing drive assembly to the elastic clamping assembly.

[0029] In use, the lower reference plate 1 serves as the basic load-bearing component of the entire tooling. The initial clamping of the Z-axis motion reference plate 103 is completed by the elastic clamping assembly, and the elastic force eliminates the gap between the Z-axis motion reference plate 103 and the clamping structure. At the same time, it avoids rigid contact that could scratch the precision surface of the reference plate. The pressurized drive assembly, in conjunction with the detection movement of the module slide 308, generates high-pressure gas, which is transmitted to the elastic clamping assembly through two flow guiding assemblies. This dynamically strengthens the fixing force of the Z-axis motion reference plate 103. Simultaneously, it works with the measuring instruments to complete the motion accuracy detection of the module slide 308.

[0030] like Figure 1 - Figure 9As shown, in one embodiment, the elastic clamping assembly includes several sets of sleeves 212 distributed circumferentially along the inner wall of the fixed frame 201. The sleeves 212 support components such as the transmission plate 202 and the push plate 207. The inner walls of the multiple sleeves 212 are movably fitted with transmission plates 202. The transmission plates 202 transmit the force of the push plate 207 and the first spring 206, driving the connecting rod 203 and the pressure plate 204 to move synchronously. One side of each of the multiple transmission plates 202 is fixedly connected to a connecting rod 203, which connects the transmission plate 202 to the pressure plate 204 to transmit the force. The end of each connecting rod 203 away from the transmission plate 202 is fixedly connected to a pressure plate 204, which is a clamping component. A flexible wear-resistant bonding plate 205 is fixedly installed on the side of the multiple clamping plates 204 facing the Z-axis motion reference plate 103 to apply clamping force. The flexible wear-resistant bonding plate 205 is used to achieve flexible contact between the clamping plate 204 and the Z-axis motion reference plate 103, avoid scratching the precision surface of the reference plate, and improve the fit to ensure uniform clamping. The flexible wear-resistant bonding plate 205 is made of polytetrafluoroethylene, and the bonding surface of the flexible wear-resistant bonding plate 205 facing the Z-axis motion reference plate 103 is a flat and smooth surface. The inner wall of the multiple sleeves 212 is movably embedded with a push plate 207, which transmits the pushing force to the first spring 206 and the transmission plate 202 to realize the transmission and reinforcement of the clamping force.

[0031] Furthermore, multiple push plates 207 and multiple transmission plates 202 are elastically connected by a first spring 206. The first spring 206 provides an initial elastic clamping force to achieve the initial clamping of the Z-axis motion reference plate 103, and also buffers the thrust of high-pressure gas to avoid rigid impact damage to components. At the same time, it drives each component to reset after the gas pressure is released. A baffle 208 is fixedly embedded in the inner wall of multiple sleeves 212. The baffle 208 fits against the push plate 207. The baffle 208 is used to prevent the push plate 207 from sliding excessively, limit the movement stroke of the push plate 207, and ensure that the high-pressure gas can effectively act on the push plate 207. The push plate 207 can slide along the inner wall of the sleeve 212.

[0032] like Figure 1 - Figure 9 As shown, in one embodiment, the fixing frame 201 is also provided with an opening and closing adjustment component. The opening and closing adjustment component is connected to one side of two of the clamping plates 204 and is used to adjust the distance between the four clamping plates 204 to realize the clamping and disassembly of the Z-axis motion reference plate 103. The core function is to expand the clamping space, facilitate the insertion and removal of the Z-axis motion reference plate 103, and at the same time, it does not affect the effect of initial elastic clamping and dynamic strengthening fixation.

[0033] Furthermore, the opening and closing adjustment component includes a slide groove 209, an L-shaped slider 210, and a vertical plate 211. The slide groove 209 is formed on one side of the fixed frame 201 and provides a sliding track for the L-shaped slider 210, limiting the movement direction of the L-shaped slider 210 and ensuring that the L-shaped slider 210 drives the pressure plate 204 to move in a preset direction. The L-shaped slider 210 is movably embedded in the inner wall of the slide groove 209 and connects the pressure plate 204 and the vertical plate 211, transmitting the operating force of the vertical plate 211 and driving the pressure plate 204 to move. One end of the L-shaped slider 210 is connected to the pressure plate 204. The top of the clamping plate 204 is fixedly connected, and the other end is fixedly connected to the upright plate 211. The L-shaped slider 210 can slide along the inner wall of the slide groove 209, driving the clamping plate 204 to move in the direction close to or away from the Z-axis motion reference plate 103. The upright plate 211 is used to provide manual operation points, which are convenient for operators to pull or push to realize the sliding adjustment of the L-shaped slider 210, thereby adjusting the position of the clamping plate 204. There are four sleeves 212. The four sleeves 212 are respectively fixedly set at the center positions of the four sides of the inner wall of the fixed frame 201, corresponding to form four clamping plates 204.

[0034] like Figure 1 - Figure 9 As shown, in one embodiment, the pressurization drive assembly includes two fixed guide rails 307 parallel to each other on the upper side of the lower reference plate 1. The fixed guide rails 307 provide a precision motion track for the module slide 308, define the sliding direction of the module slide 308, ensure that the module slide 308 can slide smoothly along a preset trajectory, and provide a stable power source for pressurization drive. The module slide 308 is movably mounted on the fixed guide rails 307, and the module slide 308 can slide linearly along the fixed guide rails 307. As the object of detection and the power source for pressurization, its sliding motion can be converted into the power to compress the main cylinder 301. Two base plates 3 are fixedly installed at the bottom of the lower reference plate 1. A main cylinder 301 is fixedly installed on one side of each of the two base plates 3. A piston plate 302 is movably embedded in the inner wall of each of the two main cylinders 301. The piston plate 302 is used to compress the gas inside the main cylinder 301, converting the mechanical energy of the module slide 308 into the pressure energy of the gas, and generating high-pressure gas.

[0035] Furthermore, a round rod 303 is fixedly connected to one side of each of the two piston plates 302. The ends of the two round rods 303 away from the piston plates 302 are connected to a horizontal plate 304. The horizontal plate 304 is in contact with the module slide 308. The piston plates 302 can slide along the inner wall of the pressurized main cylinder 301 to compress the sealed gas inside the pressurized main cylinder 301. A second spring 305 is also provided inside the pressurized main cylinder 301 to realize the elastic reset of the piston plates 302. After the test is completed, the second spring 305 can drive the piston plates 302, round rods 303 and horizontal plate 304 to return to the initial position, release the gas pressure, and prepare for the next test.

[0036] like Figure 1 - Figure 9 As shown, in one embodiment, the two flow guiding components include a first flow guiding pipe 306, a three-way connector, and a second flow guiding pipe 309. One end of the first flow guiding pipe 306 is connected to the outlet of the pressurized main cylinder 301, and the other end is connected to the inlet of the three-way connector. The first flow guiding pipe 306 discharges the high-pressure gas generated in the pressurized main cylinder 301 and transmits it to the three-way connector. The three-way connector diverts the high-pressure gas discharged from one first flow guiding pipe 306 to multiple second flow guiding pipes 309, thereby achieving uniform distribution of high-pressure gas and ensuring that the four sleeves 212 can obtain uniform gas pressure, thus achieving uniform clamping in four directions. The number of multiple second flow guiding pipes 309 matches the number of sleeves 212. One end of the second flow guiding pipe 309 is connected to the outlet of the three-way connector, and the other end is connected to the inlet of the sleeve 212, thereby achieving the diversion and transmission of high-pressure gas and accurately transmitting the high-pressure gas to the inside of each sleeve 212, providing locking power for the elastic clamping component.

[0037] like Figure 1 - Figure 9 As shown, in one embodiment, a five-axis moving platform 101 is further provided between the lower reference plate 1 and the upper reference plate 102. The bottom of the five-axis moving platform 101 is fixedly connected to the lower reference plate 1, and the top is fixedly connected to the upper reference plate 102. During testing, the dial indicator is first fixed to the testing position on the upper side of the lower reference plate 1 using a magnetic base, so that the measuring probe of the dial indicator is in contact with the testing surface of the upper reference plate 102. The adjustment knob of the five-axis moving platform 101 is manually adjusted, and the dial indicator reading is observed in real time until the dial indicator reading stabilizes at the preset value. Within the specified accuracy range, the horizontal and vertical alignment of the upper reference plate 102 is calibrated. Then, the module slide 308 is installed on two fixed guide rails 307 to ensure that the module slide 308 can slide smoothly along the fixed guide rails 307. The position of the dial indicator is adjusted so that the measuring probe is in contact with the detection surface of the module slide 308. The module slide 308 is pushed along the fixed guide rails 307 to slide from the initial position toward the pressurized main cylinder 301. During the sliding process, the dial indicator value is read in real time, and the positional deviation on the movement trajectory of the module slide 308 is recorded.

[0038] It is worth noting that, through the coordinated cooperation of various components, this invention achieves the dual effects of initial elastic clamping and dynamic reinforcement of the Z-axis motion reference plate 103. No additional power source is required; the locking force can be synchronously strengthened using only the detection motion of the module slide 308 itself. This solves the problems of traditional rigid fixation that easily scratches the reference plate and causes deformation, as well as the problems of constant fixing force and easy loosening of the reference plate during the detection process.

[0039] Working principle: In use, the fixing frame 201 is placed into the mounting slot 2 opened in the upper reference plate 102. The two upright plates 211 are pulled manually. The upright plates 211 drive the L-shaped slider 210 to slide along the inner wall of the slide groove 209, which in turn drives the two clamping plates 204 connected to it to move backward away from the center of the mounting slot 2. This creates an installation space between the four clamping plates 204 that can accommodate the Z-axis motion reference plate 103. The Z-axis motion reference plate 103 is placed in the middle position of the four clamping plates 204. The two upright plates 211 are released. The elastic restoring force of the first spring 206 pushes the push plate 207 and the transmission plate 202 to move towards the center of the mounting slot 2, which in turn drives the connecting rod 203 and the clamping plates 204 to move synchronously. Finally, the flexible wear-resistant bonding plate 205 on the four clamping plates 204 is tightly fitted with the outer wall of the Z-axis motion reference plate 103, realizing the initial elastic clamping and fixing of the Z-axis motion reference plate 103.

[0040] Two fixed guide rails 307 are fixed parallel to each other on the upper side of the lower reference plate 1. The module slide 308 is mounted on the fixed guide rails 307 and can slide linearly along the fixed guide rails 307. A dial indicator is installed in the detection position on the upper side of the lower reference plate 1, with the measuring probe of the dial indicator facing the detection surface of the module slide 308. During the detection process, the module slide 308 is pushed along the fixed guide rails 307. The module slide 308 moves towards the pressurized main cylinder 301 and pushes the horizontal plate 304. The horizontal plate 304 drives the two round rods 303 to move synchronously into the pressurized main cylinder 301, thereby pushing the piston. Plate 302 slides along the inner wall of the pressurizing main cylinder 301, compressing the sealed gas inside the pressurizing main cylinder 301. The compressed high-pressure gas inside the pressurizing main cylinder 301 flows out through the first guide pipe 306. The outlet ends of the two first guide pipes 306 are connected to four second guide pipes 309 through three-way connectors. After being diverted by the three-way connectors, the high-pressure gas is transported to the sleeves 212 on the four sides of the fixed frame 201 through the second guide pipes 309, realizing the transmission of high-pressure gas from the pressurizing end to the clamping end. After the high-pressure gas enters the sleeve 212, it is blocked by the... The blocking effect of plate 208 causes gas pressure to act directly on the side of push plate 207 away from the first spring 206, pushing push plate 207 to slide along the inner wall of sleeve 212 towards the Z-axis motion reference plate 103. The sliding of push plate 207 is transmitted to transmission plate 202 through the first spring 206. Transmission plate 202 drives connecting rod 203 and pressing plate 204 to move synchronously towards Z-axis motion reference plate 103, further increasing the contact force between flexible wear-resistant bonding plate 205 and Z-axis motion reference plate 103, thus achieving pressure on Z-axis motion reference plate 103. The greater the distance that the module slide 308 is pushed along the fixed guide rail 307, the greater the sliding stroke of the piston plate 302 in the pressurized main cylinder 301, and the higher the pressure of the compressed gas in the pressurized main cylinder 301. The gas pressure delivered to the sleeve 212 through the guide pipe increases synchronously, and the pushing force on the push plate 207 is stronger. Finally, the pressing and fixing force of the clamping plate 204 on the Z-axis motion reference plate 103 is simultaneously enhanced, realizing the dynamic self-reinforcement of the fixing force of the Z-axis motion reference plate 103 during the module slide detection process, and ensuring the stability of the reference plate throughout the detection process.

[0041] While the module slide 308 pushes and reinforces the reference plate, the measuring probe of the dial indicator is in real time attached to the detection surface of the module slide 308 to capture the positional deviation of the module slide 308 during its movement along the fixed guide rail 307, thus completing the motion accuracy detection of the module slide 308.

[0042] After the test is completed, the module slide 308 is pulled away from the main pressurizing cylinder 301. The second spring 305 in the main pressurizing cylinder 301 is elastically reset, pushing the piston plate 302, the round rod 303, and the horizontal plate 304 back to their initial positions. The gas pressure in the main pressurizing cylinder 301, the guide pipe, and the sleeve 212 is released. After the pressure in the sleeve 212 disappears, the first spring 206 returns to its initial elastic state, driving the push plate 207, the transmission plate 202, the connecting rod 203, and the clamping plate 204 to reset away from the Z-axis motion reference plate 103, releasing the clamping fixation on the Z-axis motion reference plate 103. At this time, the two vertical plates 211 are pulled again to move the clamping plates 204 on both sides backward, so that the Z-axis motion reference plate 103 can be taken out from the mounting slot 2, completing the reset of the entire test and clamping process.

[0043] In summary, the present invention uses the lower reference plate 1 as the overall basic bearing component, and the elastic clamping structure in the mounting slot 2 realizes the detachable clamping and elastic fixation of the Z-axis motion reference plate 103. At the same time, the pressure driving structure on the lower reference plate 1, combined with the detection movement of the module slide 308, realizes the dynamic reinforcement and fixation of the Z-axis motion reference plate 103.
