[0002] The engine powertrain refers to a series of components that generate power on a vehicle and transmit it to the road. In a broad sense, it includes the engine, gearbox, drive shaft, differential, clutch, etc. But usually, the powertrain generally only refers to the engine, transmission, and the rest of the parts integrated into the transmission.

[0003] When testing the engine assembly, the assembly needs to be placed on a working bracket. However, due to the different shapes and sizes of engines, the commonly used bracket only clamps the engine assembly on a flat surface. During the clamping process, the irregular parts of the engine assembly surface cannot be fully clamped, resulting in only a few smaller surface contacts on the engine assembly surface, affecting the clamping stability effect. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a universal tooling bracket for an engine powertrain.

[0023] Two clamping mechanisms are located at both sides of the upper end of the carrier plate 5. The clamping mechanisms include two grooves 7 opened at the upper end of the carrier plate 5. The inner walls of the two grooves 7 are slidably connected with sliders 8, and the upper ends of the sliders 8 are fixedly connected with clamping plates 9.

[0024] The clamping mechanism also includes a vertical plate 10 fixedly connected to the upper end of the supporting plate 5, and a placement plate 11 is fixedly connected to the upper end of the vertical plate 10. The placement plate 11 is located between the two clamping plates 9. The side walls of the clamping plates 9 are provided with through grooves 12, and the side walls of the placement plate 11 are in contact with the inner walls of the through grooves 12.

[0025] A first clamping mechanism is provided on the placement plate 11, and the first clamping mechanism includes a first strip cavity 13 opened in the placement plate 11, and a plurality of clamping rods 14 are sealed and slidably connected to the top of the first strip cavity 13, and the lower end of the clamping rod 14 is elastically connected to the bottom of the first strip cavity 13 through a spring 15.

[0026] like Figure 3 As shown, when the irregular portion of the lower end of the engine power assembly is pressed on a plurality of clamping rods 14, the plurality of clamping rods 14 will fit with the irregular portion of the lower end of the engine power assembly, and under the elastic force of the spring 15, the clamping rods 14 can fit tightly with the irregular portion of the lower end of the engine power assembly, thereby clamping and fixing the lower end of the engine power assembly.

[0027] The inner walls of the two grooves 7 are rotatably connected with a bidirectional lead screw 16, and the side walls of the bidirectional lead screw 16 are threadedly connected to the side walls of the two sliders 8. The side wall of the bearing plate 5 is fixedly connected with a self-locking motor 17 that drives the bidirectional lead screw 16 to rotate.

[0028] A second clamping mechanism is provided on the splint 9, and the second clamping mechanism includes a second strip cavity 18 opened on the side wall of the splint 9 above the placement plate 11, and a plurality of through holes 19 are opened on the inner wall of the second strip cavity 18 close to the clamping rod 14, and a plurality of clamping membranes 20 corresponding to the plurality of through holes 19 are fixedly connected to the side wall of the splint 9, and an oil storage bag 21 is fixedly connected to the inner wall of the groove 7, and the side wall of the oil storage bag 21 away from the inner wall of the groove 7 is fixedly connected to the side wall of the slider 8, and the inner wall of the oil storage bag 21 is connected to the inner wall of the second strip cavity 18 through a hose 22, and hydraulic oil is provided in the oil storage bag 21.

[0029] like Figure 2 As shown, after the engine power assembly is placed on multiple clamping rods 14 and is stably clamped, the self-locking motor 17 is driven to rotate clockwise, and the bidirectional lead screw 16 is driven to rotate clockwise, driving the two sliders 8 to approach each other, and driving the two clamping plates 9 to approach each other. At this time, the side walls of multiple clamping membranes 20 are in contact with the side walls of the engine power assembly, and the slider 8 squeezes the oil storage bag 21 at this time, so that the hydraulic oil in the second strip cavity 18 increases, so that multiple clamping membranes 20 bulge, which can be clamped into the irregular part of the side wall of the engine power assembly, and the engine power assembly is clamped and stabilized again. In this way, the irregular part of the engine power assembly can be clamped by the first clamping mechanism and the second clamping mechanism, avoiding the problem that only one plane of the engine power assembly can be clamped in the prior art, and the irregular part of the engine assembly surface cannot be fully clamped during the clamping process, resulting in the clamping of the engine assembly surface only contacting with a few smaller surfaces, affecting its clamping stability effect.

[0030] When testing the clamping of the engine power assembly, the engine power assembly is first placed on the placement plate 11 in the center. At this time, when the irregular portion of the lower end of the engine power assembly is pressed on the multiple clamping rods 14, the multiple clamping rods 14 will fit with the irregular portion of the lower end of the engine power assembly, and under the elastic force of the spring 15, the clamping rods 14 can fit tightly with the irregular portion of the lower end of the engine power assembly, thereby clamping and fixing the lower end of the engine power assembly;

[0031] Then, the self-locking motor 17 is driven to rotate clockwise, and the bidirectional lead screw 16 is driven to rotate clockwise, driving the two sliders 8 to approach each other, driving the two clamping plates 9 to approach each other, at this time, the side walls of the multiple clamping films 20 are in contact with the side walls of the engine power assembly, and at this time, the slider 8 squeezes the oil storage bag 21, so that the hydraulic oil in the second strip cavity 18 increases, so that the multiple clamping films 20 are convex, and can be clamped into the irregular side walls of the side walls of the engine power assembly, and the engine power assembly is clamped again. Stable, in this way, the irregular part of the engine power assembly can be clamped by the first clamping mechanism and the second clamping mechanism;

[0032] The staff can then inspect the engine power assembly, and during the inspection process, the two electric push rods 2 can be adjusted to extend and retract to drive the cross plate 3 to move up and down, and the engine power assembly to move up and down. At the same time, the hydraulic cylinder 6 can be adjusted to extend and retract to drive the load-bearing plate 5 to rotate up and down, so that the angle of the engine power assembly can be changed, thereby facilitating multi-directional inspection.

[0033] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
