Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission components technology, specifically a testing device for couplings. Background Technology

[0002] In mechanical transmission systems, the half-coupling is a key component connecting the driving shaft and the driven shaft. Its compressive strength directly determines the reliability and safety of the equipment operation. Therefore, compressive strength testing is an important step in ensuring product quality during the manufacturing process of half-couplings.

[0003] Currently, traditional pressure testing of half-couplings mainly relies on manual operation. Workers need to place the half-couplings one by one under a press for pressure testing, and then manually remove them after the test. This manual testing method has obvious drawbacks: on the one hand, the long-term repetitive placement and removal actions can easily lead to worker fatigue, thereby reducing testing efficiency and affecting production progress; on the other hand, workers need to frequently approach the press during manual operation, which poses safety hazards such as pinching and crushing injuries during press operation, greatly increasing the danger of the testing process. Once an operational error occurs, it may cause serious personal injury and economic losses. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The coupling testing device in this embodiment includes an operating table 1, on which a conveying table 2, a pre-placement component 4, a loading component 3, a transfer component 5, a press 6, a parking table 8, and a unloading component 7 are integrated. The components work together to realize the automatic loading and unloading of the half coupling to complete the testing.

[0023] like Figure 3The feeding assembly 3 includes a vertical plate 31 fixed on the operating table 1. A first linear module 32 is mounted on the vertical plate 31, and two sets of guide rods 33 are fixed above and below the first linear module 32, respectively. The movable end of the first linear module 32 is connected to a movable plate 34, which can slide along the guide rods 33. A front plate 35 is fixed on the movable plate 34, and an ejection cylinder 36 is installed thereon. Four guide pillars 37 pass through the movable plate 34 and the front plate 35, and an ejection plate 38 is fixedly connected between the guide pillars 37. The top is equipped with a push cylinder 39 and a push plate 310 that is slidably connected to and fixed to the piston rod of the push cylinder 39. The push plate 310 is rotatably connected to a first transmission gear 311, and has a pair of clamping plates 312 located on both sides of the first transmission gear 311 and a side push cylinder 313 fixed thereon. The clamping plates 312 are fixed with a first rack 314 that meshes with the first transmission gear 311. The side push cylinder 313 drives the first rack 314 above, and the opening and closing of the clamping plates is realized through the gear and rack transmission to clamp the half coupling.

[0024] like Figure 4 The pre-placement assembly 4 includes an upper platform 41 fixed on the operating table 1 and coaxial with the conveyor table 2. A pre-placement platform 42 is fixed on the upper platform 41. A protrusion is formed on the top of the upper platform 41 below the pre-placement platform 42. A pair of L-shaped plates 46 are hinged to the front and rear sides of the protrusion. A pair of correction blocks 49 are also slidably set on the top of the protrusion. Both ends of the L-shaped plates 46 have waist holes. The length of the upper waist hole is shorter than that of the lower waist hole. The L-shaped plates 46 are limited to the correction blocks 49 by bolts 48 passing through the upper waist holes. A correction cylinder 43 is installed at the bottom of the operating table 1. Its piston rod is fixed to a top block 44. A pair of protruding pillars 45 are formed on the front and rear sides of the top block 44. The protruding pillars 45 are inserted into the waist holes below the L-shaped plates 46. When the feeding assembly places the product on the pre-placement platform, the correction cylinder drives the top block to rise, pushes the L-shaped plate to rotate through the protruding pillars, and drives the correction blocks to move horizontally to correct the position of the half coupling on the pre-placement platform, ensuring that placement misalignment does not affect subsequent transfer.

[0025] like Figure 5 The transfer assembly 5 includes a second linear module 51 mounted on the operating table 1. An ejector cylinder 52 is mounted on the moving end of the module, and a lifting cylinder 53 is mounted on the ejector end of the ejector cylinder 52. A clamping cylinder 54 is mounted on the ejector end of the lifting cylinder 53. Horizontal movement is achieved through the second linear module, while the ejector and lifting cylinders work together to lift and push the components. The clamping cylinder is used to grip the half-coupling to be inspected, completing the transfer between the pre-layout table and the press.

[0026] like Figure 2The unloading assembly 7 includes a tail plate 71 fixed on the operating table 1. A third linear module 78 is installed on the tail plate 71. A transverse plate 79 is fixed to the moving end of the third linear module 78. A lifting cylinder 73 is installed on the transverse plate 79. A piston rod of the lifting cylinder 73 is also slidably connected to the transverse plate 79. The transverse plate 79 completes the transverse movement by means of the third linear module. The lifting cylinder pushes out to complete the vertical movement. Two sets of second transmission gears 74 are rotatably connected to the lifting plate 72. Two pairs of plates 75 and two sets of push-clamp cylinders 76 are slidably connected to the lifting plate 72. A second rack 77 is fixed on the plate 75 and meshes with the corresponding second transmission gear 74. The push-clamp cylinder 76 drives the second rack 77. The opening and closing of the plates is realized through the gear and rack transmission to clamp the half coupling after inspection. The half coupling is then transferred to the parking platform by means of the third linear module and the lifting cylinder.

[0027] The working principle of the above embodiments is as follows:

[0028] The half-coupling to be tested is conveyed to the tail end via a conveyor table. The first linear module drives the moving plate to move, and the push cylinder pushes the lower push plate down, aligning the clamping plate of the clamping part with the half-coupling. Then, the ejection cylinder pushes the ejection plate out, placing the half-coupling between the clamping plates. Next, the side push cylinder drives the first rack to move, which in turn drives the other clamping plate to move synchronously via the first transmission gear, clamping the half-coupling. It is then conveyed to the pre-layout table. The calibration cylinder is activated, the top block rises, and the protruding column pushes the L-shaped plate to rotate around the hinge point. The top of the L-shaped plate, via bolts, drives the calibration block to move towards the center, calibrating the horizontal position of the half-coupling on the pre-layout table to ensure its center is aligned with the pre-layout table. The second linear module of the transfer assembly then drives... The clamping cylinder moves to face the half coupling on the pre-placement table, and the ejector cylinder ejects, so that the half coupling is positioned between the clamping ends of the clamping cylinder and clamped and fixed. Then, the lifting cylinder lifts up, separating the half coupling from the pre-placement table. The second linear module can then move to the press inspection station, where the press performs a pressure resistance test on the workpiece. The third linear module of the unloading assembly drives the lifting plate to move to the parking table and the press inspection station. The push cylinder descends to align the clamping plate with the workpiece, and the push-clamping cylinder drives the second rack to move, which in turn drives the clamping plate to clamp the workpiece through the second transmission gear. Subsequently, the third linear module and the push cylinder work together to transfer the workpiece to the parking table, completing the entire inspection process.
