Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary tooling technology, specifically a test bench support tooling with high stability. Background Technology
[0002] In the fields of mechanical manufacturing, equipment testing, and performance testing of components such as gearboxes, test bench support fixtures are key auxiliary equipment for achieving precise workpiece positioning, load bearing, and position adjustment. Existing support fixtures mostly employ a structure where a servo motor drives a bidirectional lead screw in conjunction with a threaded seat. The rotation of the lead screw causes the threaded seat to translate, and then a connecting rod pushes the support bench up and down to meet the height adjustment requirements under different testing conditions.
[0003] However, in practical applications, when the support platform bears heavy workpieces such as gearboxes, the weight of the workpiece continuously acts on the tooth groove of the double-acting lead screw. Under long-term stress, the tooth groove is prone to wear and deformation due to excessive pressure. This not only leads to a decrease in the adjustment accuracy and stability of the support platform, but also causes tooling failure due to lead screw damage, necessitating improvement. Therefore, we propose a highly stable test platform support fixture. Utility Model Content
[0004] The purpose of this invention is to provide a highly stable test bench support fixture, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a highly stable test bench support fixture, comprising a support frame, a support platform disposed in the middle of the inner cavity of the support frame, a servo motor disposed at the lower end of the support platform, the servo motor being detachably connected to the support frame, a bidirectional lead screw being installed at the output end of the servo motor, a threaded seat being slidably installed at the lower end of the support frame, a fixing seat being fixedly installed at the lower end of the support platform, support components for supporting and limiting the support platform being disposed on both sides of the support frame, and a limiting component disposed below the support frame for limiting the support components.
[0006] Optionally, the support assembly includes limiting frames disposed on both sides of the support frame. Multiple limiting rods are welded to the inner side of the limiting frames and are equidistantly distributed among the limiting rods. Sleeves are welded to both ends of the support platform and are movably connected to the support frame. A first spring is fixedly installed at the upper end of the limiting frame, and the other end of the first spring is fixedly connected to the upper end of the support frame.
[0007] Optionally, the limiting component includes a first toothed plate disposed below the limiting frame, a second toothed plate disposed below the first toothed plate, a slider fixedly mounted on one end of the second toothed plate, and sliding grooves provided on both sides of the lower end of the support frame. The slider is slidably connected to the sliding groove, and a second spring is fixedly mounted on the upper end of the inner cavity of the sliding groove. The other end of the second spring is fixedly connected to the slider.
[0008] Optionally, the dimensions of the bidirectional lead screw are adapted to the dimensions of the threaded seat, and the bidirectional lead screw is threadedly connected to the threaded seat.
[0009] Optionally, a connecting rod is provided between the threaded seat and the fixed seat, and the connecting rod is rotatably connected to both the threaded seat and the fixed seat.
[0010] Optionally, the size of the limiting rod is adapted to the size of the sleeve, and the limiting rod is movably connected to the sleeve.
[0011] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0012] The technical solution of this application, through the setting of a support frame, servo motor, bidirectional lead screw, limit frame, sleeve, first toothed plate, slider, and second spring, can simultaneously control the support platform to be in position and release the limit frame. Due to the spring's elasticity, the first spring drives the limit frame to move towards the center, causing the limit rod on the limit frame to insert into the sleeve on the support platform, thereby achieving support and limiting of the support platform. This further reduces the damage to the teeth of the bidirectional lead screw caused by the weight of the gearbox, thus reducing the inconvenience of frequent maintenance by operators. When adjusting the support platform, the second toothed plate can be separated from the first toothed plate, and the limit frames on both sides of the support frame can be pulled outwards until the limit rod separates from the sleeve, thus facilitating the position adjustment of the support platform and limiting the limit frame to prevent it from becoming an obstruction.

[0017] Please see Figure 1-2 This utility model provides a technical solution: a highly stable test bench support fixture, including a support frame 1, a support platform 11 disposed in the middle of the inner cavity of the support frame 1, a servo motor 12 disposed at the lower end of the support platform 11, the servo motor 12 being detachably connected to the support frame 1, a bidirectional lead screw 13 being installed at the output end of the servo motor 12, a threaded seat 14 being slidably installed at the lower end of the support frame 1, a fixed seat 15 being fixedly installed at the lower end of the support platform 1, support components for supporting and limiting the support platform 11 being disposed on both sides of the support frame 1, and a limiting component disposed below the support frame 1 for limiting the support components.
[0018] In this embodiment, during support, the gearbox is first placed on the support platform 11, and then the servo motor 12 is turned on. The servo motor 12 drives the bidirectional lead screw 13 to rotate, and the bidirectional lead screw 13 drives the threaded seat 14 to move, thereby adjusting the position of the support platform 11. This causes the gearbox on the support platform 11 to abut against the upper end of the support frame 1, thus achieving the effect of limiting the gearbox and facilitating subsequent testing of the gearbox. At the same time, the support assembly limits the support platform 11, thereby reducing the damage to the tooth grooves of the bidirectional lead screw 13 caused by the gravity pressure of the gearbox, thus reducing the trouble of frequent maintenance by the staff. Meanwhile, the limiting assembly limits the pulling of the support assembly, thereby facilitating the control of the position adjustment of the support platform 11.
[0019] In this technical solution, the support assembly includes limiting frames 2 disposed on both sides of the support frame 1. Multiple limiting rods 22 are welded to the inner side of the limiting frame 2, and the limiting rods 22 are evenly distributed. Sleeves 21 are welded to both ends of the support platform 11. The sleeves 21 are movably connected to the support frame 1. A first spring 23 is fixedly installed on the upper end of the limiting frame 2, and the other end of the first spring 23 is fixedly connected to the upper end of the support frame 1.
[0020] In this embodiment, during support, while controlling the support platform 11 to be in place, the limiting frame 2 is released. Due to the spring's elasticity, the first spring 23 drives the limiting frame 2 to move towards the center, so that the limiting rod 22 on the limiting frame 2 is inserted into the sleeve 21 on the support platform 11, thereby achieving support and limitation of the support platform 11. This further reduces the damage to the tooth groove of the bidirectional lead screw 13 caused by the gravity pressure of the gearbox, thereby reducing the trouble of frequent maintenance by the staff.
[0021] In this technical solution, the limiting component includes a first toothed plate 3 disposed below the limiting frame 2, a second toothed plate 4 disposed below the first toothed plate 3, a slider 6 fixedly installed at one end of the second toothed plate 4, and sliding grooves 5 opened on both sides of the lower end of the support frame 1. The slider 6 is slidably connected to the sliding groove 5, and a second spring 7 is fixedly installed at the upper end of the inner cavity of the sliding groove 5. The other end of the second spring 7 is fixedly connected to the slider 6.
[0022] In this embodiment, when adjusting the support platform 11, first press the second toothed plate 4 downward to separate the second toothed plate 4 from the first toothed plate 3, and then pull the limiting frames 2 on both sides of the support frame 1 to move outward until the limiting rod 22 separates from the sleeve 21. This facilitates the position adjustment of the support platform 11 and also limits the limiting frame 2, preventing the limiting frame 2 from getting in the way.
[0023] In this technical solution, the dimensions of the bidirectional lead screw 13 are matched with the dimensions of the threaded seat 14, and the bidirectional lead screw 13 is threadedly connected to the threaded seat 14.
[0024] In this embodiment, the bidirectional lead screw 13 cooperates with the threaded seat 14 to achieve the effect of lifting and adjusting the support platform 11.
[0025] In this technical solution, a connecting rod 16 is provided between the threaded seat 14 and the fixed seat 15, and the connecting rod 16 is rotatably connected to the threaded seat 14 and the fixed seat 15 respectively.
[0026] In this embodiment, the connecting rod 16 facilitates the adjustment of the support platform 11.
[0027] In this technical solution, the size of the limiting rod 22 is adapted to the size of the sleeve 21, and the limiting rod 22 is movably connected to the sleeve 21.
[0028] In this embodiment, the limiting rod 22 cooperates with the sleeve 21 to facilitate the limitation of the support platform 11.
[0029] In use, during support, first place the gearbox on the support platform 11, then turn on the servo motor 12. The servo motor 12 drives the bidirectional lead screw 13 to rotate, which in turn moves the threaded seat 14, thereby adjusting the position of the support platform 11. This causes the gearbox on the support platform 11 to abut against the upper end of the support frame 1, thus limiting the gearbox and facilitating subsequent testing. While controlling the support platform 11 to its position, release the limiting frame 2. Due to the spring's elasticity, the first spring 23 moves the limiting frame 2 towards the center, causing the limiting rod 22 on the limiting frame 2 to insert into the support. Inside the sleeve 21 on the support platform 11, the support platform 11 is further limited, which further reduces the damage to the tooth groove of the double-acting screw 13 caused by the gravity pressure of the gearbox, and reduces the trouble of frequent maintenance by the staff. When adjusting the support platform 11, first press the second tooth plate 4 downward to separate the second tooth plate 4 from the first tooth plate 3, and then pull the limiting frame 2 on both sides of the support frame 1 to move outward until the limiting rod 22 separates from the sleeve 21, which facilitates the position adjustment of the support platform 11, and can also limit the limiting frame 2 to avoid the limiting frame 2 from getting in the way.
