Description

Technical Field

[0001] This invention relates to the field of testing tooling and equipment technology, and specifically to a multi-station testing platform. Background Technology

[0002] In many situations, it is necessary to perform various performance tests on products at different locations, such as optical angle performance testing of gyroscopes and tensile force testing at different azimuth angles. Furthermore, the performance testing procedures for products often involve multiple steps. For example, gyroscopes require at least two different tests: one in a stationary state and the other in a moving state. Currently, existing testing platforms use moving modules. During testing, workpieces are installed one by one on the moving module, which can move and adjust the position of the workpieces in the X and Y directions to achieve testing in the moving state. When testing a workpiece in a stationary state is required, the moving module is not activated, keeping the workpiece stationary. However, after testing each workpiece, it must be removed and reinstalled, and the two different tests must be performed sequentially, resulting in cumbersome manual operation, long processing time, and low efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a multi-station testing platform that can reduce the cumbersomeness of manual operation, reduce time consumption, improve efficiency, occupy little space, and have a good compact structure.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A multi-station testing platform includes a base and multiple crossbeams. Each crossbeam is mounted on the base via an X-axis displacement component and can be driven by the X-axis displacement component to move and adjust its position on the base along a preset X-axis. Each crossbeam is provided with one or more workpiece carriers for mounting and positioning workpieces. Each workpiece carrier is slidably mounted on the crossbeam along a Y-axis perpendicular to the X-axis.

[0006] As a further improvement to the above technical solution:

[0007] The X-axis displacement assembly includes two lead screws rotatably mounted on the base and arranged side by side, and a drive mechanism for driving the two lead screws to rotate synchronously. Each end of the crossbeam is equipped with a nut corresponding to the two lead screws. The nuts at each end of the crossbeam are mounted on the crossbeam in a manner that allows them to rotate relative to the crossbeam around the axis of the lead screw. Each nut on the crossbeam is provided with a locking assembly that can switch between a locked state in which the crossbeam and the nut are relatively fixed and an unlocked state in which the crossbeam and the nut are allowed to rotate relative to each other.

[0008] Each crossbeam has a mounting seat for each nut, and the nut is rotatably mounted on the corresponding mounting seat. The locking assembly includes a bolt, a handle, a guide hole on the mounting seat, and a socket on the nut. The bolt is installed in the guide hole and can move along the guide hole to insert into and disengage from the socket. When the bolt is inserted into the socket, it is in a locked state, and when the bolt is disengaged from the socket, it is in an unlocked state. An elastic element is provided between the bolt and the mounting seat to force the bolt to insert into the socket. The handle is connected to the bolt and can pull to move the bolt to overcome the action of the elastic element and disengage from the socket. The locking assembly also includes a retaining mechanism for keeping the handle in the state where the bolt is disengaged from the socket.

[0009] The handle is rotatably connected to the plug. The retaining mechanism includes a slotted plate mounted on the mounting base and a locking member connected to the handle. The slotted plate has a strip-shaped hole. The locking member is connected to the handle and can rotate with the handle between a first angle and a second angle. When the locking member is at the first angle, it can pass through the strip-shaped hole to allow the plug to be inserted into and disengaged from the insertion hole. When the plug is disengaged from the insertion hole and the handle is rotated to change the locking member to the second angle, the two ends of the locking member abut against the end faces of the slotted plate on both sides of the strip-shaped hole to prevent the plug from moving in the direction of insertion into the insertion hole.

[0010] The driving mechanism includes a rotary drive component and two output shafts connected to the drive end of the rotary drive component and driven to rotate synchronously by the rotary drive component. The two output shafts are respectively connected to two lead screws through a transmission mechanism.

[0011] Two output shafts extend to both sides of the rotary drive component, and the axes of the two output shafts are perpendicular to the axes of the two lead screws. The transmission mechanism includes a first bevel gear connected to the end of the output shaft away from the rotary drive component and a second bevel gear connected to the end of the lead screw. The first bevel gear meshes with the second bevel gear.

[0012] The rotary drive includes a motor and a speed reducer whose input end is connected to the output end of the motor. The speed reducer has two output ends arranged opposite to each other, and the two output ends of the speed reducer are respectively connected to two output shafts through couplings.

[0013] The base is a rectangular frame, with two lead screws installed on a pair of opposite sides of the rectangular frame, and two output shafts and a reducer installed on one side of another pair of opposite sides of the rectangular frame.

[0014] The workpiece support is threadedly connected to a locking and positioning screw that can be tightened and loosened by screwing on the crossbeam.

[0015] The base is provided with scales for indicating the position of each crossbeam, and the crossbeams are provided with scales for indicating the position of each workpiece support.

[0016] Compared with the prior art, the advantages of the present invention are as follows:

[0017] The multi-station testing platform of this invention is equipped with multiple crossbeams that can be independently moved and adjusted on the base. Each crossbeam is equipped with one or more workpiece carriers that can be slidably adjusted along the Y direction. Multiple workpieces can be installed and removed at one time, realizing the detection of workpieces on all crossbeams moving synchronously in a moving state (first detection method), workpieces on all crossbeams moving stationarily in a stationary state (second detection method), multiple workpieces on a single crossbeam moving one by one in a moving state (third detection method), and multiple workpieces on a single crossbeam moving synchronously in a moving state (fourth detection method). Compared with the traditional technology that requires installing workpieces one by one, it can reduce the tediousness of manual operation, reduce time consumption, and improve efficiency. Simultaneously, it allows for the simultaneous inspection of workpieces on some crossbeams while another crossbeam and its workpieces remain stationary. In situations where multiple workpieces require both sequential inspection in moving states and inspection in stationary states, the time allotted for sequential inspection of multiple workpieces in moving states can be used to inspect other workpieces in stationary states. This eliminates the need to separately schedule time for stationary inspection, significantly reducing overall time consumption and further improving efficiency. Furthermore, when inspecting workpieces on a single crossbeam in a moving state, other crossbeams can be moved to either side of the base, minimizing space occupation. While meeting the movement range requirements for single crossbeam inspection in a moving state, the entire testing platform occupies a small space and boasts a compact structure.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 As shown, the multi-station testing platform of this embodiment includes a base 1 and multiple crossbeams 2. Each crossbeam 2 is mounted on the base 1 by an X-direction displacement component 3 and can be driven by the X-direction displacement component 3 to move and adjust its position on the base 1 along a preset X-direction. Each crossbeam 2 is provided with one or more workpiece bearing seats 4 for mounting and positioning workpieces. Each workpiece bearing seat 4 is slidably mounted on the crossbeam 2 in a direction perpendicular to the X-direction. This multi-station testing platform is equipped with multiple crossbeams 2 that can be independently moved and adjusted on the base 1. Each crossbeam 2 is equipped with one or more workpiece bearing seats 4 that can be slidably adjusted along the Y direction. Multiple workpieces can be installed and removed at one time, enabling the detection of workpieces on all crossbeams 2 moving synchronously for detection in a moving state (first detection method), workpieces on all crossbeams 2 moving stationarily for detection in a stationary state (second detection method), multiple workpieces on a single crossbeam 2 moving one by one for detection in a moving state (third detection method), and multiple workpieces on a single crossbeam 2 moving synchronously for detection in a moving state (fourth detection method). Compared with the traditional technology that requires installing workpieces one by one, it can reduce the tediousness of manual operation, reduce time consumption, and improve efficiency. Simultaneously, it allows for the simultaneous inspection of workpieces on some crossbeams 2 while another crossbeam 2 and its workpieces remain stationary for inspection. In situations where multiple workpieces require both sequential inspection in a moving state and inspection in a stationary state, the time allotted for sequential inspection of multiple workpieces can be used to keep other workpieces stationary for inspection. This eliminates the need to separately schedule the time for stationary inspection, significantly reducing overall time consumption and further improving efficiency. Furthermore, when inspecting workpieces on a single crossbeam 2 in a moving state, other crossbeams 2 can be moved to either side of the base 1 without occupying excessive space. While meeting the movement range requirements for inspection of a single crossbeam 2 in a moving state, the entire testing platform occupies a small space and has a compact structure.

[0025] The specific scheme for slidingly mounting the above-mentioned workpiece bearing seats 4 on the crossbeam 2 is as follows: a guide plate is fixedly installed on the crossbeam 2 to form a dovetail groove structure. The workpiece bearing seat 4 is provided with a dovetail boss structure that slides and cooperates with the dovetail groove structure, so that the workpiece bearing seat 4 can slide back and forth in a straight line along the dovetail groove structure.

[0026] In this embodiment, the X-direction displacement component 3 includes two lead screws 31 rotatably mounted on the base 1 and arranged side by side, and a drive mechanism for driving the two lead screws 31 to rotate synchronously. Each end of the crossbeam 2 is equipped with a nut 32 corresponding to the two lead screws 31. The nut 32 at each end of the crossbeam 2 is mounted on the crossbeam 2 in a manner that allows it to rotate relative to the crossbeam 2 around the axis of the lead screw 31. The crossbeam 2 is provided with a locking component corresponding to each nut 32, which can switch between a locked state in which the crossbeam 2 and the nut 32 are relatively fixed and an unlocked state in which the crossbeam 2 and the nut 32 are allowed to rotate relative to each other. On the one hand, the use of two lead screws 31 driven by the same drive mechanism to rotate, which cooperate with the lead screw nuts 32 at both ends of each crossbeam 2 to drive the movement of each crossbeam 2, is simple, compact, and low-cost compared to setting a separate drive mechanism for each crossbeam 2. Moreover, the synchronicity and consistency of all crossbeams 2 when moving synchronously are good. On the other hand, the structure of using two lead screws 31 to cooperate with the lead screw nuts 32 at both ends of the crossbeam 2 is superior to the scheme of sliding the crossbeam 2 on the base 1 and driving it with a lead screw 31 on only one side (which is prone to jamming, especially when the crossbeam 2 is long) and the scheme of sliding the crossbeam 2 on the base 1 and driving it with a lead screw 31 in the middle of the crossbeam 2 (the lead screw 31 is located in the middle of the crossbeam 2, which will interfere with the workpiece inspection). It does not require a sliding rail for the crossbeam 2. It combines the advantages of simple and compact structure while ensuring stable and reliable operation and eliminating interference. On the other hand, the locking assembly can switch between a locked state in which the crossbeam 2 and the screw nut 32 are fixed relative to each other and an unlocked state in which the crossbeam 2 and the screw nut 32 are allowed to rotate relative to each other. When switched to the locked state to fix the crossbeam 2 and the screw nut 32 relative to each other, the screw rod 31 can drive the crossbeam 2 to move. When switched to the unlocked state to allow the crossbeam 2 and the screw nut 32 to rotate relative to each other, the screw rod 31 can only drive the screw nut 32 to rotate freely, and the crossbeam 2 does not move. In this way, the crossbeam 2 can be moved or fixed as needed to meet different detection requirements, and its usage is highly flexible.

[0027] In this embodiment, as Figure 2 and Figure 3As shown, each nut 32 of the crossbeam 2 is provided with a mounting base 21. The nut 32 is rotatably mounted on the corresponding mounting base 21. The locking assembly includes a bolt 33, a handle 34, a guide hole 211 provided on the mounting base 21, and a socket 321 provided on the nut 32. The bolt 33 is installed in the guide hole 211 and can move along the guide hole 211 to insert into the socket 321 and disengage from the socket 321. When the bolt 33 is inserted into the socket 321, it is in a locked state. When the bolt 33 is disengaged from the socket 321, it is in an unlocked state. An elastic element 35 is provided between the bolt 33 and the mounting base 21 to elastically force the bolt 33 to insert into the socket 321. The handle 34 is connected to the bolt 33 and can pull and drive the bolt 33 to move to overcome the action of the elastic element 35 and disengage from the socket 321. The locking assembly also includes a retaining mechanism for keeping the handle 34 in the state where the bolt 33 is disengaged from the socket 321. When the retaining mechanism prevents the handle 34 from being in the state where the pin 33 is dislodged from the insertion hole 321, the elasticity forces the elastic element 35 to insert the pin 33 into the insertion hole 321, thereby fixing the crossbeam 2 and the nut 32 relatively. At this time, the rotation of the screw 31 will drive the crossbeam 2 to move. Operating the handle 34 can pull and drive the pin 33 to move to overcome the action of the elastic element 35 and dislodge it from the insertion hole 321. Then, by using the retaining mechanism to keep the handle 34 in the state where the pin 33 is dislodged from the insertion hole 321, the crossbeam 2 and the nut 32 can rotate relative to each other. At this time, the rotation of the screw 31 will not drive the crossbeam 2 to move, thus allowing the movement and stillness of each crossbeam 2 to be controlled as needed. This locking assembly has the advantages of simple and compact structure, stable and reliable operation, and easy operation. The specific scheme for the nut 32 to be rotatably mounted on the corresponding mounting base 21 is as follows: a through hole is provided on the mounting base 21, and the nut 32 is mounted in the through hole through a bearing, allowing it to rotate around the center line of the through hole.

[0028] In this embodiment, the handle 34 is rotatably connected to the plug 33. The retaining mechanism includes a groove plate 36 mounted on the mounting base 21 and a locking member 37 connected to the handle 34. The groove plate 36 is provided with a strip hole 361 (preferably a waist-shaped hole). The locking member 37 is connected to the handle 34 and can rotate with the handle 34 between a first angle and a second angle. At the first angle, the locking member 37 can pass through the strip hole 361 so that the plug 33 can be inserted into and dislodged from the insertion hole 321. When the plug 33 is dislodged from the insertion hole 321 and the handle 34 is rotated to switch the locking member 37 to the second angle, the two ends of the locking member 37 abut against the end faces of the groove plate 36 on both sides of the strip hole 361 to prevent the plug 33 from moving in the direction of insertion into the insertion hole 321. The handle 34 is rotatably connected to the plug 33, and with the locking part 37 and the slotted plate 36 with the strip hole 361, the handle 34 is kept in the state where the plug 33 is dislodged from the socket 321 and the state of unlocking is achieved. The structure is simple, easy to manufacture and assemble, low in cost, and easy to operate.

[0029] In this embodiment, the driving mechanism includes a rotary drive component 38 and two output shafts 39 connected to the drive end of the rotary drive component 38 and driven synchronously by the rotary drive component 38. The two output shafts 39 are respectively connected to two lead screws 31 through a transmission mechanism. By using a single rotary drive component 38 connected to two lead screws 31 through two output shafts 39 to drive the two lead screws 31 to rotate synchronously, the structure is simple, cost-effective, energy-efficient, and has good synchronization.

[0030] In this embodiment, two output shafts 39 extend to both sides of the rotary drive member 38, and the axes of the two output shafts 39 are perpendicular to the axes of the two lead screws 31. The transmission mechanism includes a first bevel gear connected to the end of the output shaft 39 away from the rotary drive member 38 and a second bevel gear connected to the end of the lead screw 31, with the first bevel gear meshing with the second bevel gear. The bevel gears allow the connection structure between the rotary drive member 38 and the output shaft 39 to span between the two lead screws 31 and be located at the ends of the two lead screws 31, which improves the structural compactness, requires fewer transmission components, and ensures stable and reliable transmission.

[0031] In this embodiment, the rotary drive 38 includes a motor 381 and a reducer 382 whose input end is connected to the output end of the motor 381. The reducer 382 has two output ends arranged opposite to each other, and the two output ends of the reducer 382 are respectively connected to two output shafts 39 through couplings 383.

[0032] In this embodiment, the base 1 is a rectangular frame, and two lead screws 31 are respectively installed on a pair of opposite sides of the rectangular frame. Two output shafts 39 and a reducer 382 are installed on one of the other pair of opposite sides of the rectangular frame. The two lead screws 31, two output shafts 39 and reducer 382 are distributed on three of the sides of the rectangular frame base 1, which has a compact structure and occupies little space.

[0033] In this embodiment, the workpiece support 4 is threadedly connected to a locking and positioning screw 41 that can be tightened and loosened by screwing on the crossbeam 2. Tightening the locking and positioning screw 41 to tighten the crossbeam 2 keeps the workpiece support 4 fixed relative to the crossbeam 2. Tightening the locking and positioning screw 41 to loosen the crossbeam 2 allows the workpiece support 4 to slide and adjust its position along the crossbeam 2, thereby realizing the adjustment and fixation of the workpiece support 4 on the crossbeam 2 to meet the needs of different workpiece installation positions and movement ranges.

[0034] In this embodiment, the base 1 is provided with scales for indicating the position of each crossbeam 2, and the crossbeam 2 is provided with scales for indicating the position of each workpiece support 4, so as to facilitate reading and determining the position of the workpiece support 4.

[0035] The above description is merely a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the inventive concept should also be considered within the scope of protection of the present invention.
