[0029] The present utility model will be further described below with reference to the drawings and specific embodiments.

[0030] Refer to Figures 1 to 6 , a quantitative valve moving and positioning device, comprising a moving trolley. A horizontal rotating mechanism is arranged above the moving trolley. The horizontal rotating mechanism is connected to the moving trolley through a lifting mechanism. A swinging mechanism is connected to the left side of the horizontal rotating mechanism. The swinging mechanism is connected to a fixing component through a universal joint. The quantitative valve can be installed on the fixing component, and then the horizontal rotating mechanism can be controlled to rotate through the lifting mechanism. At this time, the quantitative valve is driven to move.

[0031] The lifting mechanism 5 among them includes a sleeve 501. The sleeve 501 is fixed on the moving trolley and is vertically arranged. The sleeve 501 is a cylindrical body. The upper end of the sleeve 501 is in an open state and the lower end is in a closed state. A lifting rod 502 is arranged inside the sleeve. The lifting rod is a hydraulic cylinder. The lifting rod is movably connected to the sleeve. The lower end of the lifting rod is fixed on the moving trolley. Its central axis coincides with the central axis of the sleeve and can extend and contract inside the sleeve. The upper end of the lifting rod is butted with a transition rod 6 and is connected to the horizontal rotating mechanism through the transition rod 6. At this time, the horizontal rotating mechanism can move vertically accordingly.

[0032] The above-mentioned horizontal rotation mechanism includes a rocker arm 7. The rocker arm 7 is in the shape of a long arm. A vertically extending first bearing hole is provided in the middle of the rocker arm 7. A first bearing is installed in the first bearing hole. The inner ring of the first bearing is connected to a transition rod 6. The transition rod 6 is a cylindrical rod. The rocker arm 7 can rotate around the central axis of the transition rod 6. A balance assembly 17 is provided at the right end of the rocker arm 7. Two fixing plates 18 are provided at the position of the rocker arm 7 close to the swing mechanism. An operation instruction plate 19 is installed between the fixing plates 18. The operation instructions of this quantitative valve movement positioning device are recorded on the operation instruction plate 19, which is convenient for the operator to view when using;

[0033] To make the overall stability better, the balance assembly 17 includes a hanging plate 1701. The hanging plate 1701 is a disc with a hanging rod provided at the center. A hook is provided at the upper end of the hanging rod. A barb is provided at the right end of the rocker arm 7. The hook can be hung on the barb. Weight blocks 1702 are placed on the hanging plate 1701. There are multiple weight blocks 1702, which are detachably connected to the hanging plate 1701. By changing the number of weight blocks 1702 on the hanging plate 1701, the rocker arm 7 can be adjusted to keep the rocker arm 7 in a balanced state.

[0034] It should be noted that when controlling the movement of the fixing component, it is controlled by the swing mechanism, that is, the fixing component moves along with the swing of the swing mechanism. The swing mechanism includes a hanging arm 8. The hanging arm 8 is in the shape of a short arm. The left end of the hanging arm 8 is connected to the fixing component, and a first support rod 9 is hinged at this end of the hanging arm 8. The first support rod 9 is a rigid straight rod. The other end of the first support rod 9 is connected to a transition disc 10. The transition disc 10 is an annular disc body. The transition disc 10 is sleeved on the sleeve 501. The transition disc 10 can slide along the length direction of the sleeve 501. An adjustment disc 11 is provided below the transition disc 10. The adjustment disc 11 and the transition disc 10 form a swing adjustment assembly. The adjustment disc 11 is an annular disc body. The central axis of the transition disc 10 coincides with the central axis of the adjustment disc 11. The adjustment disc 11 is in contact with the transition disc 10. The adjustment disc 11 can support the transition disc 10. The adjustment disc 11 is also sleeved on the sleeve 501. The adjustment disc 11 is threadedly connected to the sleeve 501. Internal threads are provided on the adjustment disc 11. External threads are provided on the side wall of the sleeve 501. By screwing the adjustment disc 11, the adjustment disc 11 can move up and down along its central axis. When the adjustment disc 11 moves upward, the transition disc 10 will also be pushed upward. After the transition disc 10 moves upward, it will drive the first support rod 9 to move, so that the horizontal position of the lower end of the first support rod 9 gradually rises. At this time, the angle between the first support rod 9 and the hanging arm 8 changes, thereby driving the hanging arm 8 to move. The right end of the hanging arm 8 is hinged to the rocker arm 7. When the rocker arm 7 rotates horizontally, it will drive the hanging arm 8 to rotate horizontally, so that the quantitative valve on the fixing component is located at the approximate position, and then through the swing of the hanging arm 8, the quantitative valve will swing accordingly to adjust the displacement of the quantitative valve.

[0035] The boom 8 is connected to the fixed component through a universal joint 12, and the universal joint 12 has a locking function and can be locked in a fixed position;

[0036] The fixed component includes a mounting box 13. The mounting box is connected to the universal joint 12. The mounting box 13 is customized according to the external dimensions of the metering valve 14 and is generally composed of a bottom plate, two side plates, and a back plate. The metering valve 14 is placed in the mounting box 13. Set screws are provided on the side plates of the mounting box 13. By screwing the set screws tightly, the metering valve 14 can be fixed in the mounting box. After the metering valve 14 enters the box, it can be fixed by screwing the set screws tightly. A backing plate is provided between the set screw and the metering valve 14. The backing plate is connected to the set screw. When the set screw fixes the metering valve 14, the backing plate can reduce the pressure of the set screw on the metering valve 14 and prevent damage to the metering valve 14.

[0037] Refer to Figure 7 and Figure 8 As another embodiment of the present utility model, the settings of the transition disk and the adjustment disk in the above embodiment are cancelled. At this time, a second bearing hole is provided at the center of the end face at the lower end of the transition rod 6, and a second bearing 26 is installed in the second bearing hole. The inner ring of the second bearing is connected to the lifting rod 502. The transition rod 6 can rotate in the horizontal direction. The transition rod 6 is fixedly connected to the rocker arm 7. In this way, when the transition rod 6 rotates, it will drive the rocker arm 7 to rotate. At the same time, the swing adjustment assembly includes a chute 24 provided on the side wall of the transition rod 6. A slider 25 is provided in the chute 24. The slider 25 is connected to the support rod 9. When the slider 25 slides up and down in the chute 24, the angle between the support rod 9 and the boom changes, but it is always connected to the outer wall chute 24 of the transition rod 6. Therefore, the support rod 9 will push the boom 8 to swing outwards. On the contrary, when the support rod 9 slides down in the chute, the support rod 9 will push the boom to swing inwards. The up and down flipping of the boom 8 can drive the metering valve to move, increasing flexibility.

[0038] The movement of the slider 25 in the chute 26 can be realized by external control. For example, an electric push-pull rod is provided in the chute. The electric push-pull rod is fixed on the lower surface of the rocker arm, and the output end of the electric push-pull rod is fixed on the slider. When the electric push-pull rod shortens, it can drive the slider to move upwards.

[0039] In addition, the mobile trolley in this device includes a mobile box 1. The mobile box 1 is a cuboid box body. A base 15 is fixedly connected to the bottom of the mobile box 1. The base 15 is a rectangular plate member. The mobile wheels are installed under the base 15. The number of mobile wheels 16 is four, which are respectively arranged at the four corners of the base. All four mobile wheels can rotate freely. There are two push handles 4 on the upper surface of the mobile box 1. The push handles 4 are fixedly connected to both sides of the upper surface of the mobile box 1. The mobile box 1 can be moved in different directions through the push handles 4. The mobile trolley can move the metering valve positioning device to the workpiece beside which grease needs to be added;

[0040] A box door 2 is arranged on the above-mentioned mobile box 1. The lower edge of the box door 2 is hinged to the mobile box. The box door 2 can be opened and closed. A clamping plate 3 is arranged on the mobile box. The clamping plate 3 is hinged to the mobile box. When the box door 2 is in the closed state, the upper edge of the box door 2 is buckled with the mobile box. Rotating the clamping plate 3 can fix the upper edge of the box door 2. Two counterweight blocks 22 are arranged in the mobile box 1 to avoid the mobile vehicle 1 being top-heavy and prevent tipping over. The two counterweight blocks 22 are respectively arranged on both sides inside the mobile box. A placement plate 23 is arranged between the counterweight blocks 22, and some tools can be placed on it.

[0041] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model.
