The cover 12 covers only the injection region 112. The detection area 111 is provided with the clamping device 2, and before detection, the oil pump to be detected needs to be clamped. And the oil pump to be inspected is different in size and cannot work well in the tank 11. The cover 12 is sized and shaped to be larger than that shown in fig. 1, for example. The oil splashing in the oil spraying area 112 can be prevented, the installation and the disassembly of the oil pump to be detected by the clamping device 2 are not influenced in the detection area 111. The box cover 12 is connected with the box body 11 through a hinge, so that friction force between the box cover 12 and the box body 11 is reduced, and rotation is smoother.

Further, the clamping portion 21 includes a clamping housing 211, a first clamping frame 212, a second clamping frame 213, and a bi-directional screw 214; the first clamping frame 212 and the second clamping frame 213 are both connected to the bi-directional screw 214; the bidirectional screw 214 is rotationally connected with the clamping shell 211;

the adjusting part 22 includes an adjusting housing 221, a first gear 222, a second gear 223, a screw 224, and an adjusting wheel 225; the adjusting housing 221 is disposed on a side wall of the clamping housing 211; one end of the bi-directional screw 214 passes through the clamping housing 211 to be connected with the first gear 222; the first gear 222 and the second gear 223 are meshed with each other; one end of the screw 224 is connected with the second gear 223 through the adjusting housing 221; the other end of the screw 224 penetrates through the side wall of the box 11 to be connected with the adjusting wheel 225.

As shown in fig. 1. The first clamping frame 212 and the second clamping frame 213 move in opposite directions. The bi-directional screw 214 rotates, and the first clamping frame 212 and the second clamping frame 213 respectively move in opposite directions, so as to realize the function of opening and closing to achieve the clamping. The clamping housing 211 is hollow. One end of the bi-directional screw 214 is rotatably connected to the clamping housing 211 at the inner side. The other end of the bi-directional screw 214 passes through the clamping housing 211 to be connected with the first gear 222. Wherein, the first gear 222 and the second gear 223 are bevel gears. And the first gear 222 is intermeshed with the second gear 223. The adjusting housing 221 is a housing covering the first gear 222 and the second gear 223. The screw 224 is rotatably connected to both the housing 11 and the adjusting housing.

And rubber pads are arranged on the first clamping frame 212 and the second clamping frame 213 at positions which are contacted with the oil pump to be detected. The rubber pad not only can increase the friction force with the oil pump to be detected, but also can increase the contact area with the oil pump to be detected. Further improves the clamping effect and ensures that the oil pump to be detected is clamped tightly. The situation that the oil pump to be detected falls off or cannot work due to vibration generated during working is avoided.

The adjustment wheel 225 is a folding hand wheel. The handle of the adjusting wheel 225 can be folded and placed, so that the space can be saved when the adjusting wheel is placed at ordinary times in an idle mode.

Further, the side wall of the box body 11 is also provided with a lifting device 4; the lifting device 4 is connected with a driving device 3.

Further, the driving device 3 includes a three-jaw chuck 31 and a motor 32; the driving end of the motor 32 is connected with the three-jaw chuck 31.

The three-jaw chuck 31 is generally composed of a chuck body, movable jaws, and a jaw driving mechanism. The three-jaw chuck 31 of the present utility model may be adjusted directly by hand of a worker. Because the oil pumps with small volumes are clamped by the detection rack, an electric adjustment chuck is not needed. Not only saves energy consumption, but also can achieve the effect of adjusting clamping. Since the structure and the working principle of the three-jaw chuck 31 are all the prior art, the description thereof will not be repeated here.

Further, the lifting device 4 includes a sliding rail 41 and a telescopic rod 42; the fixed part of the sliding rail 41 is connected with the side wall of the box 11; the fixed end of the telescopic rod 42 is connected with the sliding part of the sliding rail 41; the telescopic end of the telescopic rod 42 is connected with the driving device 3.

The slide rail 41 is further provided with a locking member on the outer side, and the slide rail 41 can be locked. Thereby realizing the positioning effect. The telescopic rod 42 is used for positioning and calibrating the driving device 3.

Further, an oil filling hole is formed at the bottom of the side wall of the detection area 111; the control valve 5 is communicated with the outside of the oil filling hole of the detection area 111. The control valve 5 adopts a BUC-4 type hand valve. The operator can flexibly control the opening and closing state of the control valve 5, thereby controlling the oil amount in the detection area 111.

The quick connecting pipes with corresponding calibers are designed and manufactured aiming at the oil pumps to be detected of various types, so that the stability of connection can be improved. Thereby achieving better detection effect. As shown in fig. 2 and 3, one end of the meter 61 is located outside the case cover 12, the measuring end of the meter 61 is located in the measuring tube 62, and the measuring tube 62 is disposed inside the case cover 12.

Further, a handle 121 is provided on the top of the case cover 12. The handle 121 may facilitate the operator to open and close the cover 12.

Further, a supporting beam 7 is arranged at the bottom of the box body 11. The depth of the detection area 111 is different from that of the oil injection area 112, so that the working effect of the engine oil pump to be detected can be more intuitively seen. Therefore, the support beam can keep the whole of the case 11 in a horizontal state.

Further, an oil guide plate 113 is disposed at the bottom of the oil spraying area 112. The oil guide plate 113 is inclined at an angle to the horizontal plane. And the end of the oil guide plate 113 away from the detection area 111 is higher. The oil guide plate 113 is disposed in a manner as shown in fig. 2. In this way, the oil ejected from the oil pump to be detected can flow into the detection area 111 again according to the inclination of the oil guide plate 113. The oil liquid in the detection area 111 is recycled. Saving resources and saving more labor.

Working principle:

the adjustment wheel 225 is turned to open the first clamping frame 212 and the second clamping frame 213. An oil pump to be tested is placed between the first clamping frame 212 and the second clamping frame 213.
