Description

Technical Field

[0001] This invention relates to the field of product testing technology, specifically to a device and method for detecting the verticality of a direct-drive oscillating head. Background Technology

[0002] Direct-drive oscillating heads are a type of drive method for the end effector or specific joints of a robotic arm. The core feature is that the oscillating head is driven directly by a drive device such as a motor, without the need for intermediate transmission structures such as reducers or gears. The end effector oscillating head of the robotic arm undertakes core tasks such as positioning, operation, and detection. Its motion accuracy, response speed, and control flexibility directly determine the overall performance of the robotic arm.

[0003] In the production of direct-drive oscillating heads for robotic arms, including manufacturing, assembly, and debugging, the use of testing devices is a core element in ensuring that the final performance meets standards. The core advantages of direct-drive oscillating heads—high precision, high response, and accurate force control—require extremely high requirements for hardware machining accuracy, assembly errors, and control system matching. Testing devices are used to identify and correct errors, defects, or performance deficiencies that may occur during the production process, ultimately ensuring that the product meets the needs of actual applications.

[0009] Preferably, the outer wall of the lead screw is threaded with a crossbar, a guide rail is provided at the contact point between the top plate and the crossbar, the inner wall of the crossbar is slidably connected to the outer wall of the guide rail, and two sets of connecting sleeves are provided on the outer walls of the crossbar in opposite directions.

[0010] Preferably, an adjusting rod is rotatably connected to the inner wall of the connecting sleeve. Two sets of adjusting rods are arranged opposite each other and connected in the middle by a double-ended screw. The double-ended screw is used to control the opening and closing angle of the two sets of adjusting rods.

[0011] Preferably, a frame plate is rotatably connected to the lower side of the adjusting rod, and a mounting groove is provided in the middle of the frame plate, and the measuring component is installed inside the mounting groove.

[0012] Preferably, the measuring component includes a detection bracket, a steering rod is fixedly connected to the inner wall of the detection bracket, connecting sleeves are installed on the outer walls of both sides of the steering rod, a cleaning block is fixedly connected to the bottom end of the connecting sleeves, a fixing block is installed in the middle of the steering rod, an adjusting rod is slidably connected to the inner wall of the fixing block, and a dial indicator is detachably installed on the bottom end face of the adjusting rod.

[0014] A method for detecting the verticality of a direct-drive oscillating head includes the following steps:

[0015] When the device is needed, first pull the handle on the front of the slide to move the slide to the front. Then, install the direct drive oscillating head body to be tested in the corresponding slot on the slide. Then push the slide to the bottom of the rear side. Start the electric push rod to drive the adjusting ring to pull under the limit ring. The switching sleeve slides outside the irregular shaft and engages with the connecting end on the right. At this time, start the motor to drive the irregular shaft to rotate and drive the switching sleeve to rotate. Drive the threaded section to rotate through the connecting end on the right and drive the adjusting block to move. This will drive the probe to be inserted into the groove in the middle of the direct drive oscillating head body. The direct drive oscillating head body is U-shaped, and through holes are opened on one side of the U and the upper and lower sides for measurement. After the probe is inserted into place, the adjusting block drives the outer wall limit plate and rotates while moving, which drives the clamping rod to unfold and clamp. Thus, the clamping plate fixes the direct drive oscillating head body during use, preventing the direct drive oscillating head body from shaking during the measurement process.

[0016] After clamping, the second motor on the top plate drives the second lead screw to rotate inside the L-shaped base, thereby driving the crossbar to adjust up and down within the limits of the top plate and guide rail to adapt to the height of different products. After a wide range of adjustment via the crossbar, the first adjusting rod is unfolded and folded by adjusting the double-ended lead screw, thus making a small floating adjustment, which drives the frame plate to move downward, thereby driving the detection bracket to insert into the through hole on either the upper or lower side of the direct drive swing head body. After installation, by installing a dial indicator or sensor on the lower side of the second adjusting rod and rotating the steering rod, the detection bracket is driven to rotate. The bracket rotates on the inner wall of the frame plate to inspect one side of the through hole of the direct drive oscillating head body. During the inspection, the measuring section of the dial indicator is used to detect the openings on the upper and lower sides of the direct drive oscillating head body. As the probe rotates, it moves from one side to the other, thereby obtaining the array of through holes and probes. This allows the determination of the center point between the through holes on the upper and lower sides and the through hole on one side, thus determining whether the direct drive oscillating head body is a good product. During use, when the steering rod drives the inspection bracket to rotate, the connecting sleeve 2 and the cleaning block clean the inside of the through hole, preventing dust or foreign objects from causing inaccurate measurements.

[0017] After testing one side, start motor two to drive screw two to rotate, causing the crossbar to rise, which in turn drives the frame plate to rise. After rising, start the electric push rod to drive the switching sleeve to engage with the connecting end on the left side. At this time, the connecting end drives the rotating frame to rotate, thereby completing the function of driving the clamping plate and the direct drive swing head body to flip. In this way, it can quickly flip over to measure the other side during use.

[0018] This invention provides a device and method for detecting the verticality of a direct-drive oscillating head. It has the following beneficial effects:

[0019] 1. This invention, through the cooperation of electric push rod, connecting rod and switching sleeve, can not only clamp and fix the direct drive oscillating head body through the drive adjustment block and clamping rod during use, but also flip the direct drive oscillating head body for testing after the test is completed, thereby improving the testing speed during use.

[0020] 2. This invention uses motor two and lead screw two to drive the crossbar to complete rapid adjustment, and at the same time combines adjustment rod one and double-ended lead screw to complete fine adjustment. During use, it can achieve the effect of rapid positioning and adjustment adaptation for different products and measurement.

[0021] 3. When the rotating steering rod drives the detection bracket to rotate on the inner wall of the frame plate, the present invention can not only achieve the cleaning effect through the upper and lower through holes of the direct drive swing head body of the cleaning block, but also complete the quick replacement and installation of the dial indicator through the lead screw, the clamp and the mounting sleeve, so as to achieve the effect of changing different measuring instruments according to different usage scenarios.

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] Please see the appendix Figure 1 - Appendix Figure 4 This invention provides a verticality detection device for a direct-drive oscillating head, comprising an L-shaped base 1, a motor 2 fixedly connected to the outer wall of the L-shaped base 1, a non-circular shaft 3 fixedly connected to the output end of the motor 2, a switching sleeve 4 slidably connected to the outer wall of the non-circular shaft 3, two sets of connecting ends 5 rotatably connected to the outer wall of the non-circular shaft 3, toothed grooves on both sides of the inner wall of the switching sleeve 4 engaging with the connecting ends 5, an adjusting ring 7 rotatably connected to the outer wall of the switching sleeve 4, a connecting rod 8 fixedly connected to the lower side of the adjusting ring 7, limit rings 6 rotatably connected to both sides of the adjusting ring 7, the inner wall of the limit ring 6 fixedly connected to the outer wall of the switching sleeve 4, and the outer wall of the left connecting end 5 fixedly connected to the outer wall of the switching sleeve 4. A rotating frame 10 is fixedly connected, and the outer wall of the rotating frame 10 is rotatably connected to the inner wall of the L-shaped base 1. An electric push rod 9 is fixedly connected to the rear outer wall of the L-shaped base 1. The output end of the electric push rod 9 is fixedly connected to the bottom end of the connecting rod 8. A threaded section is provided on the outer wall of the right connecting end 5. An adjusting block 11 is threadedly connected to the outer wall of the threaded section. A clamping rod 12 is connected to the outer wall limit plate of the adjusting block 11 by a rotating shaft. A clamping plate 13 is threadedly connected to the outer wall of the clamping rod 12. A detection component is provided at the front end of the adjusting block 11. A feeding component is provided below the detection component. An adjusting component is provided at the top of the L-shaped base 1. A measuring component is provided in the middle of the adjusting component.

[0034] Specifically, first, pull out the feeding assembly, install the direct-drive oscillating head body 15 inside the groove, and then start the electric push rod 9 to drive the connecting rod 8 and the adjusting ring 7 to slide the switching sleeve 4 on the outer wall of the irregular shaft 3 under the limit of the limiting ring 6. This achieves the effect of adjusting the position of the switching sleeve 4 during use. When the switching sleeve 4 engages with the right connecting end 5, as... Figure 4As shown, the motor 2 drives the shaped shaft 3 to rotate, which in turn drives the switching sleeve 4 to rotate. The shaped shaft 3 rotates freely inside the connecting end 5, thus driving the switching sleeve 4 to rotate. This, combined with the connecting rod 8 and adjusting ring 7, achieves the effect of adjustment and drive during use. When the connecting end 5 on the right rotates, the threaded section drives the adjusting block 11 to move under the condition of threaded rotation, thereby pushing the probe 14 into the interior of the direct drive oscillating head body 15, achieving rapid positioning during use. Simultaneously, when the adjusting block 11 rotates, the clamping rod 12, connected by a rotating shaft to the outer wall limiting plate, acts as a connection and drive mechanism, thereby causing the clamping plate 13 to clamp the direct drive oscillating head body 15, firstly preventing the direct drive oscillating head body 15 from... Displacement occurs during the testing process, and after the first test, it is used for subsequent flipping. Then, the height of the frame plate 23 is adjusted by the adjustment component, and then the measurement component is used for measurement. After the initial measurement is completed, the height is adjusted again by the measurement component to return to the safety limit. The electric push rod 9 drives the connecting rod 8 and the adjusting ring 7 to pull the switching sleeve 4 and the connecting end 5 on the left side under the limit ring 6. After the engagement is completed, the starting motor 2 drives the irregular shaft 3 to rotate the rotating frame 10, thereby driving the clamping rod 12 and the clamping plate 13 to rotate the direct drive swing head body 15, thus achieving the effect of measuring on the other side. During use, it achieves rapid flipping while also fixing the direct drive swing head body 15 to prevent shaking.

[0035] Please see the appendix Figure 1 - Appendix Figure 3 The detection assembly includes a probe 14, the rear outer wall of the probe 14 is fixedly connected to the front outer wall of the adjusting block 11 and the threaded section rotates in the middle of the probe 14, the front side of the probe 14 is slidably connected to a direct drive swing head body 15, and one side of the clamping rod 12 is rotatably connected to the outer wall of the rotating frame 10.

[0036] Specifically, the test bar 14 serves to center the middle of the direct drive oscillating head body 15 during use. When measuring with the dial indicator 30, the deviation of the center part can be measured through the upper and lower through holes. The upper and lower surfaces of the direct drive oscillating head body 15 are the test surfaces. During use, the accuracy of the product through holes is judged by the upper and lower surfaces and the dial indicator 30.

[0037] Please see the appendix Figure 1 - Appendix Figure 2 The feeding component includes a slide plate 34. The upper surface of the slide plate 34 is provided with a groove that fits against the lower surface of the direct drive swing head body 15. The inner wall of the slide plate 34 is slidably connected to a slide rail 35. The lower surface of the slide rail 35 is fixedly connected to the outer wall of the L-shaped base 1. Two sets of slide rails 35 are arranged opposite each other. A handle is provided on the front side of the slide plate 34 to assist in feeding.

[0038] Specifically, the slide plate 34 serves as both a load-bearing and mounting plate. During use, the cooperation between the slide plate 34 and the slide rail 35 not only facilitates quick and convenient material loading but also positions the direct drive swing head body 15 using the groove. This also allows for easy removal after testing to test the next set of results. In use, it enhances the testing effect and provides auxiliary positioning, thereby accelerating the testing speed.

[0039] Please see the appendix Figure 5 - Appendix Figure 6 The adjustment assembly includes a top plate 16, the lower surface of which is fixedly connected to the upper surface of an L-shaped base 1. A second motor 17 is fixedly connected to the upper surface of the top plate 16, and a second lead screw 18 is fixedly connected to the output end of the second motor 17. The outer wall of the second lead screw 18 is rotatably connected to the interior of the L-shaped base 1. A crossbar 19 is threadedly connected to the outer wall of the second lead screw 18. A guide rail is provided at the contact point between the top plate 16 and the crossbar 19. The inner wall of the crossbar 19 is slidably connected to the outer wall of the guide rail. Two sets of connecting sleeves 20 are provided on the outer walls of the crossbar 19. An adjustment rod 21 is rotatably connected to the inner wall of the connecting sleeve 20. Two sets of adjustment rods 21 are arranged opposite each other and connected in the middle by a double-ended lead screw 22. The double-ended lead screw 22 is used to control the opening and closing angle of the two sets of adjustment rods 21. A frame plate 23 is rotatably connected to the lower side of the adjustment rod 21. A mounting groove is provided in the middle of the frame plate 23, and the measuring assembly is installed inside the mounting groove.

[0040] Specifically, during operation, motor 17 drives lead screw 18 to rotate, which in turn drives crossbar 19 to move up and down. Two sets of crossbar 19 are connected by a central support plate 23. A horizontal shaft connects the two sets of crossbar 19 at their ends, allowing for synchronous control. During operation, adjusting rod 21 rotates under the limit of connecting sleeve 20 and can be adjusted via the central double-ended lead screw 22, enabling fine-tuning. Lead screw 18 plays a primary adjustment role. When testing products of different heights, long-distance positioning can be achieved using lead screw 18 and crossbar 19. Finally, fine-tuning is completed using adjusting rod 21 and the double-ended lead screw 22, thus adapting to different direct-drive oscillating head bodies 15 for measurement.

[0041] Please see the appendix Figure 6 - Appendix Figure 7The measuring assembly includes a detection bracket 24, a steering rod 25 fixedly connected to the inner wall of the detection bracket 24, connecting sleeves 26 installed on both outer walls of the steering rod 25, a cleaning block 27 fixedly connected to the bottom end of the connecting sleeves 26, a fixing block 28 installed in the middle of the steering rod 25, an adjusting rod 29 slidably connected to the inner wall of the fixing block 28, and a dial indicator 30 detachably installed on the bottom end face of the adjusting rod 29. A groove is provided on the top of the dial indicator 30.

[0042] Specifically, during use, the detection bracket 24 installed inside the frame plate 23 rotates by rotating the steering rod 25 after positioning. This, along with the connecting sleeve 26 and cleaning block 27, cleans the inner diameter of the through hole in the direct drive oscillating head body 15. Simultaneously, the position of the dial indicator 30 can be adjusted by the adjusting rod 29. This allows for adjustment of the dial indicator 30's position according to actual usage. Furthermore, as the dial indicator 30 rotates one full turn from one side of the test bar 14 to the other, it obtains data on the inner diameter of the through hole and whether the upper and lower through holes and one side through hole are perpendicular, thus completing the product testing.

[0043] Example 2:

[0044] Based on Embodiment 1, this embodiment addresses the problem in the prior art where the detection component is an integrated, fixed type, leading to inaccurate measurement accuracy due to difficulty in replacement and other issues during use. As a further step, the present invention provides a second embodiment for the measurement component during use:

[0045] Please see the appendix Figure 7 - Appendix Figure 8 The adjusting rod 29 has an internal mounting sleeve 33. The inner wall of the mounting sleeve 33 is slidably connected to a clamp 32. The clamp 32 and the dial indicator 30 are installed by a screw rod 31. The outer wall of the screw rod 31 fits into the internal groove of the dial indicator 30.

[0046] Specifically, when a different measurement and testing method is required, the dial indicator 30 can be replaced with a laser rangefinder or laser sensor. If the dial indicator 30 is damaged, it can be quickly installed by rotating the lead screw 31 and inserting the clamp 32 into the mounting sleeve 33. This allows for quick installation of the dial indicator 30 according to actual product requirements and the needs of the on-site equipment. To address the issue of measurement accuracy deviations caused by the elasticity of the mounting sleeve 33, the top surface of the lead screw 31 is aligned with the bottom surface of the adjusting rod 29 and the mounting sleeve 33. This limits the movement of the sleeve during use, and the large-scale contact with the adjusting rod 29 prevents wobbling during operation.

[0047] Please see the appendix Figure 1 - Appendix Figure 7 A method for detecting the verticality of a direct-drive oscillating head includes the following steps:

[0048] When the device is needed, first pull the handle on the front side of the slide plate 34 to move the slide plate 34 to the front. Then, install the direct drive swing head body 15 to be tested into the corresponding slot on the slide plate 34. Then, push the slide plate 34 to the rear bottom. Start the electric push rod 9 to drive the adjusting ring 7 to be pulled under the limit of the limit ring 6. The switching sleeve 4 slides outside the irregular shaft 3 and engages with the connecting end 5 on the right side. At this time, the starting motor 2 drives the irregular shaft 3 to rotate, which drives the switching sleeve 4 to rotate and drives the thread through the connecting end 5 on the right side. The segment rotates and drives the adjusting block 11 to move, thereby driving the probe 14 to be inserted into the groove in the middle of the direct drive oscillating head body 15. The direct drive oscillating head body 15 is U-shaped, and through holes are opened on one side and the upper and lower sides of the U-shape for measurement. After the probe 14 is inserted into place, the adjusting block 11 drives the outer wall limiting plate and rotates to drive the clamping rod 12 to unfold and clamp while moving. Thus, the clamping plate 13 fixes the direct drive oscillating head body 15 during use, which prevents the direct drive oscillating head body 15 from shaking during measurement.

[0049] After clamping, the motor 17 on the top plate 16 drives the lead screw 18 to rotate inside the L-shaped base 1, thereby driving the crossbar 19 to adjust up and down under the limit of the top plate 16 and the guide rail to adapt to the height of different products. After a wide range of adjustment by the crossbar 19, the adjusting rod 21 is unfolded and folded by adjusting the double-headed lead screw 22, thereby making a small floating adjustment, driving the frame plate 23 to move downward, thereby driving the detection bracket 24 to be inserted into the through hole on either the upper or lower side of the direct drive swing head body 15. After installation, by installing the dial indicator 30 or sensor on the lower side of the adjusting rod 29, the steering rod 25 is rotated. When the steering rod 25 rotates, The test bracket 24 rotates on the inner wall of the frame plate 23, thereby testing one side of the through hole of the direct drive oscillating head body 15. During the test, the measuring section of the dial indicator 30 is used to test the openings on the upper and lower sides of the direct drive oscillating head body 15. As the dial indicator rotates, it rotates from one side of the test bar 14 to the other side, thereby obtaining the array of through holes and test bar 14. This allows the determination of the center point between the through holes on the upper and lower sides and the through hole on one side, thus determining whether the direct drive oscillating head body 15 is a good product. During use, when the steering rod 25 drives the test bracket 24 to rotate, the connecting sleeve 26 and the cleaning block 27 clean the inside of the through hole, preventing dust or foreign objects from causing inaccurate measurements.

[0050] After testing one side, start motor 17 to drive screw 18 to rotate, causing crossbar 19 to rise, which in turn drives frame 23 to rise. After rising, start electric push rod 9 to drive switching sleeve 4 to engage with connecting end 5 on the left. At this time, connecting end 5 drives rotating frame 10 to rotate, thereby completing the function of driving clamp 13 and direct drive swing head body 15 to flip. In this way, it can quickly flip to measure the other side during use.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

When clamping, start the motor two (17) on the upper side of the top plate (16) to drive the screw two (18) to rotate inside the L-shaped base (1), thereby driving the cross rod (19) to adjust up and down under the limitation of the top plate (16) and the guide rail, adapting to the height of different products. After a large range of adjustment by the cross rod (19), adjust the double-end screw (22) to expand and fold the adjusting rod one (21), thereby making a small floating adjustment, driving the bracket plate (23) to move downward, thereby driving the detection support (24) to insert into the through hole inside either side of the straight drive swing head body (15). At this time, after installation, install the micrometer (30) or sensor on the lower side of the adjusting rod two (29), rotate the steering rod (25), and when the steering rod (25) rotates, drive the detection support (24) to rotate on the inner wall of the bracket plate (23), thereby detecting the through hole of the straight drive swing head body (15). When detecting, the measuring section of the micrometer (30) detects the opening at the upper and lower sides of the straight drive swing head body (15) when rotating, from one side of the probe rod (14) to the other side, thereby obtaining the array of the through hole and the probe rod (14), thereby judging the center point of the through hole on one side and the through hole on the other side, thereby judging whether the straight drive swing head body (15) is a good product. In the process of use, when the steering rod (25) drives the detection support (24) to rotate, the connecting sleeve two (26) and the cleaning block (27) play a role in cleaning the inside of the through hole, avoiding the problem of inaccurate measurement caused by dust or foreign matter. After detecting one side, first start the motor two (17) to drive the screw two (18) to rotate, so that the cross rod (19) rises, thereby driving the bracket plate (23) to rise. After rising, start the electric push rod (9) to drive the switching sleeve (4) to engage with the left connecting end (5). At this time, the connecting end (5) drives the rotating frame (10) to rotate, thereby completing the function of driving the clamping plate (13) and the straight drive swing head body (15) to flip, thereby completing the quick flipping for measuring the other side in the process of use.
