Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0013] Reference Figure 1-8A positioning and clamping assembly for processing brake levers of light personal vehicles includes a brake lever mounting platform 1 and a brake lever 7. A first mounting seat 2 and a second mounting seat 9 are fixed on the brake lever mounting platform 1. A positioning boss 3, matching the internal contour of the brake lever 7, is fixed on the first mounting seat 2. Two positioning bosses 3 are provided. The brake lever 7 consists of a left brake lever and a right brake lever, which are respectively matched with the two positioning bosses 3, thus allowing simultaneous positioning of the left and right brake levers. The left and right brake levers are respectively engaged with the two positioning bosses 3. A third positioning component 6 for positioning the end of the brake lever 7 is installed on the first mounting seat 2. The third positioning component 6... The brake lever 7 is positioned at its end to prevent it from shifting. Both ends of the first mounting base 2 are fixed with a third mounting base 10. The third mounting base 10 is equipped with a first positioning component 4 for positioning the hinge hole in the middle of the brake lever 7. The second mounting base 9 is equipped with a second positioning component 5 for positioning the hinge hole at the end of the brake lever 7. The second positioning component 5 positions the hinge hole at the end of the brake lever 7, and the first positioning component 4 positions the hinge hole in the middle of the brake lever 7. This prevents the brake lever 7 from rotating during processing. The third mounting base 10 is equipped with a fixing component 8 for fixing the brake lever 7. The fixing component 8 fixes the brake lever 7 to prevent it from falling off or shaking after positioning.

[0014] Reference Figure 5 The first positioning component 4 includes a first fixed seat 41, a first cylinder 42, a first positioning pin 43, and a first rubber sleeve 44. The first fixed seat 41 is fixed on the third mounting seat 10. The first cylinder 42 is mounted on the first fixed seat 41. The piston rod of the first cylinder 42 is fixed with the first positioning pin 43. The first positioning pin 43 matches the hinge hole in the middle of the brake lever 7. The first positioning pin 43 is inserted into the hinge hole in the middle of the brake lever 7. The first rubber sleeve 44 is sleeved on the first positioning pin 43. The piston rod of the first cylinder 42 pushes the first positioning pin 43 into the hinge hole in the middle of the brake lever 7. The first rubber sleeve 44 abuts against the brake lever 7, which can avoid rigid contact and has a protective function.

[0015] Reference Figure 6The second positioning assembly 5 includes a second fixed seat 51, a second cylinder 52, a connecting block 53, a lifting seat 54, a fixing plate 55, a second positioning pin 56, a second rubber sleeve 57, a slider 58, and a slide rail 59. The second fixed seat 51 is fixed on the second mounting seat 9. The second cylinder 52 is mounted on the second fixed seat 51. The piston rod of the second cylinder 52 is hinged to the connecting block 53. The lifting seat 54 is fixed on the connecting block 53. The fixing plate 55 is fixed on the lifting seat 54. Two second positioning pins 56 are fixed to the top of the fixing plate 55. The second positioning pins 56 are inserted into the hinge at the end of the brake lever 7. Inside the hole, a second rubber sleeve 57 is fitted onto the second positioning pin 56. A slider 58 is fixed to the side of the lifting seat 54, and a slide rail 59 is fixed to the side of the second mounting seat 9. The slider 58 is slidably mounted on the slide rail 59. The piston rod of the second cylinder 52 pushes the connecting block 53 to move. The connecting block 53 drives the fixing plate 55 to move synchronously through the lifting seat 54. The fixing plate 55 drives the second positioning pin 56 to move synchronously. The two second positioning pins 56 are respectively inserted into the hinge holes at the ends of the left brake lever and the right brake lever. The second rubber sleeve 57 can prevent the second positioning pin 56 from rigidly contacting the brake lever 7, thus providing protection.

[0016] Reference Figure 7 The third positioning component 6 includes a fixing rod 61 and a limiting block 62. The fixing rod 61 is fixed on the first mounting base 2, and two symmetrically arranged limiting blocks 62 are fixed on the fixing rod 61. The limiting blocks 62 abut against the end of the brake lever 7 to prevent the brake lever 7 from moving.

[0017] Reference Figure 8The fixing assembly 8 includes a third fixing seat 81, a third cylinder 82, a first connecting rod 83, a second connecting rod 84, a push rod 85, a pressure block 86, a fourth fixing seat 87, and a third connecting rod 88. The third fixing seat 81 is fixed to the third mounting seat 10. The cylinder body of the third cylinder 82 is hinged to the third fixing seat 81. The fourth fixing seat 87 is fixed inside the third fixing seat 81. The piston rod of the third cylinder 82 and the fourth fixing seat 87 are hinged together by the third connecting rod 88. The second connecting rod 84 is hinged to the fourth fixing seat 87. The piston rod of the third cylinder 82 and the second connecting rod 84 are hinged together by the first connecting rod 83. A push rod 85 is fixed to the second connecting rod 84. One end of the cylinder is fixed with a pressure block 86. The piston rod of the third cylinder 82 pushes the first connecting rod 83 and the third connecting rod 88 to rotate. Since the third connecting rod 88 is hinged to the fourth fixed seat 87, the hinge point between the piston rod of the third cylinder 82 and the first connecting rod 83 can only rotate about the hinge point between the third connecting rod 88 and the fourth fixed seat 87. As the first connecting rod 83 abuts against the second connecting rod 84, it pushes the second connecting rod 84 to rotate on the fourth fixed seat 87. During the rotation of the second connecting rod 84, it drives the push rod 85 to move synchronously. The push rod 85 drives the pressure block 86 to move synchronously. The pressure block 86 presses tightly against the brake lever 7, thereby fixing the brake lever 7. The operation is convenient and the response is fast.

[0018] Working principle: When in use, the brake lever 7 consists of a left brake lever and a right brake lever. The left and right brake levers are matched with two positioning bosses 3 respectively, so that the left and right brake levers can be positioned at the same time. The left and right brake levers are respectively snapped into the two positioning bosses 3. The third positioning component 6 positions the end of the brake lever 7 to prevent movement. The second positioning component 5 positions the hinge hole at the end of the brake lever 7. The first positioning component 4 positions the hinge hole in the middle of the brake lever 7, which can prevent the brake lever 7 from rotating during processing. The fixing component 8 fixes the brake lever 7 to prevent it from falling off or shaking after positioning.

[0019] The operating principle of the first positioning component 4 is as follows: the piston rod of the first cylinder 42 pushes the first positioning pin 43 to insert into the hinge hole in the middle of the brake lever 7, and the first rubber sleeve 44 abuts against the brake lever 7, which can avoid rigid contact and has a protective function.

[0020] The operating principle of the second positioning component 5 is as follows: the piston rod of the second cylinder 52 pushes the connecting block 53 to move, the connecting block 53 drives the fixed plate 55 to rise and fall synchronously through the lifting seat 54, the fixed plate 55 drives the second positioning pin 56 to move synchronously, and the two second positioning pins 56 are respectively inserted into the hinge holes at the ends of the left brake lever and the right brake lever. The second rubber sleeve 57 can prevent the second positioning pin 56 from rigidly contacting the brake lever 7, and has a protective function.

[0021] The operating principle of the third positioning component 6 is: the limiting block 62 abuts against the end of the brake lever 7 to prevent the brake lever 7 from moving.

[0022] The operating principle of the fixing component 8 is as follows: the piston rod of the third cylinder 82 pushes the first connecting rod 83 and the third connecting rod 88 to rotate. Since the third connecting rod 88 is hinged to the fourth fixing seat 87, the hinge point between the piston rod of the third cylinder 82 and the first connecting rod 83 can only rotate about the hinge point between the third connecting rod 88 and the fourth fixing seat 87. Thus, since the first connecting rod 83 abuts against the second connecting rod 84, it pushes the second connecting rod 84 to rotate on the fourth fixing seat 87. During the rotation of the second connecting rod 84, it drives the push rod 85 to move synchronously. The push rod 85 drives the pressure block 86 to move synchronously. The pressure block 86 presses tightly against the brake lever 7, thereby fixing the brake lever 7. The operation is convenient and the response is fast.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
