[0003] The brake fluid reservoir consists of a reservoir body and a cap. The cap is screwed onto the reservoir body to assemble the brake fluid reservoir. Currently, the industry commonly uses manual tightening of the cap, which is inefficient and makes it difficult to ensure consistent tightening torque, affecting the assembly quality of the brake fluid reservoir. Therefore, an improvement is needed. Utility Model Content

[0006] A capping device for a brake fluid reservoir includes a frame, a clamping assembly, and a capping assembly; the frame is provided with a first positioning groove and a second positioning groove, and the two ends of the brake fluid reservoir are respectively limited to the first positioning groove and the second positioning groove; the clamping assembly includes a first driving member and a clamping block; the first driving member is disposed on the frame and is used to drive the clamping block to clamp the brake fluid reservoir;

[0007] The cap screwing assembly includes a mounting plate, a clamping member, a second driving member, and a third driving member; the clamping member is rotatably connected to the mounting plate and is used to clamp the oil cap of the brake fluid reservoir; the second driving member is disposed on the mounting plate and is used to drive the clamping member to rotate; the third driving member is disposed on the frame and is used to drive the mounting plate to move closer to or away from the brake fluid reservoir.

[0008] By adopting the above technical solution, in practical application, the staff first places the brake fluid reservoir on the frame, so that the two ends of the brake fluid reservoir are respectively limited to the first positioning groove and the second positioning groove to achieve the positioning of the brake fluid reservoir. The first driving component works, so that the clamping block presses against the brake fluid reservoir to achieve the fixing of the brake fluid reservoir.

[0009] Next, the cap of the brake fluid reservoir is clamped in the clamping member. The third drive member drives the mounting plate closer to the brake fluid reservoir, thereby driving the clamping member closer to the brake fluid reservoir, so that the cap is close to the tightening point. At the same time, the second drive member drives the clamping member to rotate, thus tightening the cap. The operation is simple and convenient, which improves the assembly efficiency of the brake fluid reservoir and ensures the consistency of the tightening torque, thereby improving the assembly quality of the brake fluid reservoir.

[0010] Preferably, the clamping member includes a rotating base, multiple connectors and multiple clamping blocks. One end of the rotating base is rotatably connected to the mounting plate, the multiple connectors are snapped onto the other end of the rotating base and are spaced apart along the circumference of the rotating base, and each clamping block is detachably connected to each connector.

[0011] By adopting the above technical solution, by setting a rotating seat, multiple connectors and multiple clamping blocks, the lid is clamped between multiple clamping blocks, and each clamping block is detachably connected to each connector. Different sizes of clamping blocks can be replaced to suit different sizes of brake fluid reservoirs.

[0012] Preferably, the clamping member further includes a plurality of connecting bolts, one end of which passes through the clamping block and is threaded to the connector, and the other end abuts against the clamping block.

[0013] By adopting the above technical solution and setting multiple connecting bolts, a detachable connection between the clamping block and the connector can be achieved, resulting in a simple structure and convenient operation.

[0014] Preferably, the clamping block has a positioning groove on the side near the connector, and the connector is embedded in the positioning groove.

[0015] By adopting the above technical solution and setting a positioning groove, the clamping block can be positioned and installed so that the connecting bolts can connect the clamping block and the connector.

[0016] Preferably, the clamping member further includes a plurality of elastic blocks, each of the elastic blocks being detachably connected to the inner side of each clamping block.

[0017] By adopting the above technical solution and setting multiple elastic blocks, the elastic blocks have a certain elastic deformation capacity, which makes it easier to clamp the lid of the brake fluid reservoir and prevents damage to the clamped oil reservoir, thereby improving the assembly quality of the brake fluid reservoir.

[0018] Preferably, the clamping block has a groove on its inner side, and the elastic block is embedded in the groove.

[0019] By adopting the above technical solution and setting the groove, the elastic element block can be elastically embedded in the groove, thereby improving the stability of the elastic element installed on the clamping block.

[0024] Preferably, the diameter of the first transmission wheel is smaller than the diameter of the second transmission wheel.

[0025] By adopting the above technical solution, and by setting the diameter of the first transmission wheel to be smaller than that of the second transmission wheel, the second driving component drives the clamping component to rotate at a reduced speed, making the tightening of the lid more stable.

[0026] Preferably, the screw cap assembly further includes a protective cover disposed on the mounting plate to cover the first drive wheel, the second drive wheel and the drive belt.

[0027] By adopting the above technical solution and setting up a protective cover, the first transmission wheel, the second transmission wheel, and the transmission belt are protected.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By clamping the cap of the brake fluid reservoir into the clamping member, the third drive member drives the mounting plate closer to the brake fluid reservoir, thereby driving the clamping member closer to the brake fluid reservoir, so that the cap is close to the tightening point. At the same time, the second drive member drives the clamping member to rotate, thus achieving the tightening of the cap. The operation is simple and convenient, which improves the assembly efficiency of the brake fluid reservoir and ensures the consistency of the tightening torque, thereby improving the assembly quality of the brake fluid reservoir.

[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0038] This application discloses a capping device for a brake fluid reservoir.

[0039] Reference Figure 1 and Figure 2 The capping device includes a frame 1, a clamping assembly 2, and a capping assembly 3. The frame 1 is placed on a table. The frame 1 has a first positioning groove 323a11 and a second positioning groove 323a12. The shapes of the first positioning groove 323a11 and the second positioning groove 323a12 are respectively adapted to the shapes of the two ends of the brake fluid reservoir 4, so that the two ends of the brake fluid reservoir 4 are respectively confined in the first positioning groove 323a11 and the second positioning groove 323a12.

[0040] The clamping assembly 2 includes a first driving member 21 and a clamping block 22. The first driving member 21 is a cylinder, but in other embodiments it can also be a hydraulic cylinder, an electric push cylinder, etc. The first driving member 21 is vertically fixedly connected to the frame 1, and the clamping block 22 is fixedly connected to the power output shaft of the first driving member 21. When the first driving member 21 works, it drives the clamping block 22 to move downward and clamp it against the brake oil reservoir 4.

[0041] The cap-tightening assembly 3 includes a mounting plate 31, a clamping member 32, a second drive member 33, and a third drive member 34. The mounting plate 31 is located above the brake fluid reservoir 4. The upper end of the clamping member 32 is rotatably connected to the mounting plate 31, and the lower end of the clamping member 32 is used to clamp the cap of the brake fluid reservoir 4. The second drive member 33 is a servo motor, which is fixedly connected to the mounting plate 31 and is used to drive the clamping member 32 to rotate. The third drive member 34 is also a cylinder, and the power output shaft of the third drive member 34 is fixed to the upper side of the mounting plate 31 to drive the mounting plate 31 closer to or further away from the brake fluid reservoir 4.

[0042] In practical applications, the operator first places the brake fluid reservoir 4 on the frame 1, so that the two ends of the brake fluid reservoir 4 are respectively limited to the first positioning groove 323a11 and the second positioning groove 323a12 to achieve the positioning of the brake fluid reservoir 4. Then, the first driving component 21 is activated, so that the clamping block 22 slides downward to press the brake fluid reservoir 4, thereby fixing the brake fluid reservoir 4.

[0043] Afterwards, the operator clamps the cap of the brake fluid reservoir 4 into the lower end of the clamping member 32, activates the third drive member 34 to drive the mounting plate 31 closer to the brake fluid reservoir 4, thereby driving the clamping member 32 closer to the brake fluid reservoir 4, so that the cap moves to the tightening position. At the same time, the second drive member 33 drives the clamping member 32 to rotate, thus tightening the cap. The operation is simple and convenient, which improves the assembly efficiency of the brake fluid reservoir 4. Furthermore, under the action of the second drive member 33 and the third drive member 34, the consistency of the tightening torque can be guaranteed, thereby improving the assembly quality of the brake fluid reservoir 4.

[0044] Reference Figure 3 and Figure 4In some embodiments, the clamping member 32 includes a rotating base 321, multiple connectors 322, and multiple clamping blocks 323. The rotating base 321 is rotatably connected to the mounting plate 31. The connectors 322 are T-shaped, and the lower end of the rotating base 321 has a T-shaped slot (not marked in the figure), so that each connector 322 is engaged with the rotating base 321, and the multiple connectors 322 are evenly spaced along the circumference of the rotating base 321. Each clamping block 323 is detachably connected to the lower end of each connector 322. The lid is clamped between the multiple clamping blocks 323 to facilitate the installation of the lid. Different sizes of clamping blocks 323 can be replaced to accommodate different sizes of lids, thus enabling the assembly of brake fluid reservoirs 4 of different sizes.

[0045] Reference Figure 4 In some embodiments, the clamping member 32 further includes a plurality of connecting bolts 324, the upper end of the connecting bolts 324 passing through the clamping block 323 and threadedly connected to the connector 322, and the lower end of the connecting bolts 324 abutting against the clamping block 323, thereby realizing a detachable connection between the clamping block 323 and the connector 322, which is simple in structure and easy to operate.

[0046] In some embodiments, a positioning groove 323a is provided on the upper side of the clamping block 323, and the connector 322 is embedded in the positioning groove 323a to realize the positioning installation between the clamping block 323 and the connector 322, so that the holes between the clamping block 323 and the connector 322 correspond to each other, so that the connecting bolt 324 can be threadedly connected to the connector 322, thereby facilitating the connection between the clamping block 323 and the connector 322 by the connecting bolt 324.

[0047] In some embodiments, the clamping member 32 further includes a plurality of elastic blocks 35, the number of which is the same as the number of clamping blocks 323. Each elastic block 35 is also detachably connected to the inner side of each clamping block 323 by a connecting bolt 324. The elastic blocks 35 replace the clamping blocks 323 in contact with the reservoir cap. Because the elastic blocks 35 have a certain elastic deformation capacity, they can clamp the reservoir cap effectively without damaging the clamped reservoir, thereby improving the assembly quality of the brake fluid reservoir 4.

[0048] In some embodiments, a groove 323b is provided on the inner side of the clamping block 323, and the elastic block 35 is elastically embedded in the groove 323b to further realize the connection between the elastic block 35 and the clamping block 323, so as to improve the stability of the elastic element installed on the clamping block 323.

[0049] In some embodiments, the inner side of the elastic block 35 is arranged in an arc shape to improve the clamping effect on the lid.

[0050] Reference Figure 3In some embodiments, the cap-screwing assembly 3 further includes a connector 36. Specifically, the connector 36 includes a first drive wheel 361, a second drive wheel 362, and a drive belt 363. In this embodiment, the first drive wheel 361 and the second drive wheel 362 are pulleys, and correspondingly, the drive belt 363 is a belt. In other embodiments, the first drive wheel 361 and the second drive wheel 362 can also be sprockets, and correspondingly, the drive belt 363 is a chain. The first drive wheel 361 is fixedly connected to the power output shaft of the second drive member 33, and the second drive wheel 362 is fixedly connected to the upper end of the rotating seat 321. The drive belt 363 is connected to the first drive wheel 361 and the second drive wheel 362. When the second drive member 33 is activated, it drives the first drive wheel 361 to rotate, which in turn drives the second drive wheel 362 to rotate under the transmission of the drive belt 363, thereby realizing the rotation of the clamping member 32.

[0051] In some embodiments, the diameter of the first drive wheel 361 is smaller than the diameter of the second drive wheel 362, so as to reduce the speed of the second drive member 33 driving the clamping member 32 to rotate, making the tightening of the lid more stable.

[0052] In some embodiments, the screw cap assembly 3 further includes a protective cover 37, which is fixedly connected to the mounting plate 31 and covers the first drive wheel 361, the second drive wheel 362 and the drive belt 363, thereby protecting the first drive wheel 361, the second drive wheel 362 and the drive belt 363.

[0053] The implementation principle of this embodiment is as follows: In practical application, the operator first places the brake fluid reservoir 4 on the frame 1, so that the two ends of the brake fluid reservoir 4 are respectively limited to the first positioning groove 323a11 and the second positioning groove 323a12 to achieve the positioning of the brake fluid reservoir 4. The first driving member 21 is activated, so that the clamping block 22 slides downward to press the brake fluid reservoir 4, thereby fixing the brake fluid reservoir 4.

[0054] Afterwards, the operator clamps the cap of the brake fluid reservoir 4 into the lower end of the clamping member 32, activates the third drive member 34 to drive the mounting plate 31 closer to the brake fluid reservoir 4, thereby driving the clamping member 32 closer to the brake fluid reservoir 4, so that the cap moves to the tightening position. At the same time, the second drive member 33 drives the clamping member 32 to rotate, thus tightening the cap. The operation is simple and convenient, which improves the assembly efficiency of the brake fluid reservoir 4. Furthermore, under the action of the second drive member 33 and the third drive member 34, the consistency of the tightening torque can be guaranteed, thereby improving the assembly quality of the brake fluid reservoir 4.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
