Description

Technical Field

[0001] This utility model relates to the field of automotive parts assembly technology, specifically to an inverted brake master cylinder diaphragm assembly fixture. Background Technology

[0002] Plunger-type brake master cylinders are widely used in braking systems because they can meet the requirements of large brake fluid flow, long stroke and large displacement of vehicles. Plunger-type brake master cylinders have the advantages of simple structure, low mass production cost and long service life, but they also have their own unique structure. It is necessary to assemble annular cups into the grooves of the master cylinder. The existing method requires manual squeezing of the cups into the cup grooves. This assembly method is very slow, inefficient and easy to damage the cups, which poses a safety hazard of brake failure.

[0003] To address the aforementioned deficiencies, existing technology (Chinese Patent No. CN206317004U, Publication Date: 2017-07-1) provides a brake master cylinder cup assembly fixture. A first limiting part is inserted into the brake master cylinder, driving the center column so that the distance between the center column and the opening of the second sleeve is the same as the width of the cup. The first sleeve is driven so that the first lug fully extends out of the opening of the first sleeve. The end of the second sleeve near the first limiting part is flush with the opening of the first sleeve. The first limiting part and the ends of the second sleeve near the first limiting part respectively limit the upper and lower end faces of the cup. The distance between the first limiting part and the ends of the second sleeve near the first limiting part corresponds precisely to the position where the cup is installed in the brake master cylinder. The cup expands and returns to its natural state, at which point the cup is precisely in the cup position within the brake master cylinder. Rotating the brake master cylinder ensures that the cup is fully engaged with its installation position.

[0004] In the above-mentioned scheme, during the assembly process, the piston cup is installed in the brake master cylinder by using a sleeve and limiting part of fixed size. However, in actual assembly operations, there are many types of brake cylinders and piston cups. This leads to the need to change different assembly tools when assembling brake cylinders and piston cups of different specifications, which makes the operation inconvenient and reduces the efficiency of assembly. Utility Model Content

[0005] The purpose of this utility model is to provide an inverted brake master cylinder cup assembly fixture to solve the problem mentioned in the background art that the existing assembly fixture is not convenient to adapt to the specifications of the assembled brake master cylinder and cup during use, thus resulting in low practicality of the assembly fixture.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an inverted brake master cylinder cup assembly fixture, comprising a base plate, a positioning frame for fixing the brake master cylinder symmetrically arranged on the top of the base plate, a top frame installed in the middle of the top surface of the base plate, a mounting plate connected to the bottom of the top frame via a first cylinder, an outer support plate for supporting the edge of the cup being slidably arranged at equal angles around the bottom of the mounting plate, a circular plate connected to the middle of the bottom surface of the mounting plate via a second cylinder, and an inner support plate that abuts against the inside of the cup being slidably connected at equal angles to the bottom of the circular plate;

[0007] The positioning frame is slidably connected with abutment rods at equal intervals, and the inner end of the abutment rods is in contact with the outer wall of the brake master cylinder.

[0008] The mounting plate has an internal adjustment mechanism that adjusts the position of the outer support plate according to the size of the diaphragm cup.

[0009] The bottom of the mounting plate and the interior of the circular plate are provided with extension components, and the extension components adjust the extension range of the inner support plate according to the size of the leather cup.

[0010] Furthermore, the top of the base plate is symmetrically provided with transverse grooves, in which electric push rods are installed. The end of the electric push rod is fixed with a positioning frame, which slides in contact with the transverse groove. The positioning frame is set as an "L" shaped structure when viewed from the front, and the top of the positioning frame is set as an arc-shaped structure.

[0011] Furthermore, the top of the positioning frame is slidably connected to an abutment rod via a spring. The abutment rod penetrates the inner wall of the positioning frame and is fitted with an electromagnet. The electromagnet is positioned opposite to a magnetic sheet, and the magnetic sheet is fixed to the front and rear sides of the abutment rod.

[0012] Furthermore, the adjusting component includes an inner cavity opened inside the mounting plate, a motor is installed at the top of the inner cavity, a turntable is connected to the output end of the motor, and an inclined guide groove is opened at the bottom of the turntable at an equal angle, with an outer support plate slidably connected in the guide groove.

[0013] Furthermore, the upper part of the outer support plate is slidably connected to the limiting groove, the outer support plate forms a horizontal sliding structure through the guide groove and the limiting groove, and the bottom of the outer support plate is set as a sliding structure.

[0014] Furthermore, the adjusting component includes a piston plate fixed to the side of the outer support plate, the piston plate being slidably connected in the oil chamber, and the oil chamber being correspondingly opened on the bottom inner side of the mounting plate.

[0015] Furthermore, the inside of the oil cavity is connected to the inside of the sleeve through a connecting pipe. The sleeve is fixed on the inner wall of the slide groove, which is opened at an equal angle at the bottom of the circular plate. A sleeve rod is slidably connected in the sleeve, and an inner support plate is fixed on the outside of the sleeve rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This inverted brake master cylinder cup assembly fixture can, during use, conform to the shape and specifications of the brake cylinder to maintain the maximum contact area with the outside of the brake master cylinder, thereby maintaining the stability during assembly. At the same time, the size of the assembly parts can be adjusted according to the specifications of the cup to adapt to the assembly of cups of different specifications, thus improving the practicality of the assembly fixture.

[0018] 1. Further, the electric push rod pushes the positioning frame to slide in the transverse groove, and the positioning frame contacts the outside of the brake master cylinder. Then, the abutment rod on the positioning frame will slide on the positioning frame and compress the spring. At this time, the electromagnet is in a de-energized state, which can better fit with the outside of the brake master cylinder, thereby maintaining the effective contact area with the brake master cylinder. After clamping and fixing, the electromagnet is energized, and the magnetic sheet is attracted and fixed to the electromagnet, making the positioning more stable.

[0019] 2. Furthermore, after the motor drives the turntable to rotate, the turntable drives the guide groove to rotate accordingly, and the guide groove drives the outer support plate to move accordingly. When the outer support plate moves, it will be limited by the limiting groove, which will cause the outer support plate to open and close and slide. The outer support plate supports and fixes the edge of the piston cup and is placed in the inlet of the piston cup groove of the brake master cylinder.

[0020] 3. Furthermore, when the outer support plate moves, it will drive the piston plate to slide synchronously in the oil chamber, thereby transporting the oil in the oil chamber to the sleeve. The oil injected into the sleeve will push the sleeve rod to slide. After the sleeve rod slides, it will drive the inner support plate to move, thereby contacting the inner side of the piston cup. The second cylinder will drive the inner support plate to move down, pushing the piston cup into the piston cup groove of the brake master cylinder, thus completing the assembly work. The operation is convenient and fast, and has good adaptability. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1: Please refer to Figure 1 - Figure 6 The present invention provides the following technical solution: an inverted brake master cylinder cup assembly fixture, including a base plate 1, a positioning frame 4 for fixing the brake master cylinder symmetrically arranged on the top of the base plate 1, a top frame 9 installed in the middle of the top surface of the base plate 1, a mounting plate 11 connected to the bottom of the top frame 9 by a first cylinder 10, an outer support plate 12 for supporting the edge of the cup slidably arranged at equal angles around the bottom of the mounting plate 11, a circular plate 14 connected to the middle of the bottom surface of the mounting plate 11 by a second cylinder 13, an inner support plate 15 that abuts against the inside of the cup slidably connected at equal angles to the bottom of the circular plate 14, abutting rods 5 slidably connected through the positioning frame 4 at equal intervals, the inner end of the abutting rods 5 abutting against the outside of the brake master cylinder, an adjusting component installed inside the mounting plate 11, and the adjusting component adjusts the position of the outer support plate 12 according to the cup size, an extension component is provided at the bottom of the mounting plate 11 and inside the circular plate 14, and the extension component adjusts the extension range of the inner support plate 15 according to the cup size;

[0030] In use, the brake master cylinder is placed on the base plate 1, and the brake master cylinder is limited and fixed by the positioning bracket 4. The abutment rod 5 can increase the contact area with the outside of the brake master cylinder and improve the stability of the positioning and fixing. According to the specifications of the brake master cylinder, the specifications of the matching piston cup will not be different. Therefore, it is necessary to adjust the position of the outer support plate 12 and the inner support plate 15. The position of the outer support plate 12 is changed by the adjusting component so that the outer support plate 12 fits against the inner wall of the piston cup. The position of the inner support plate 15 is changed by the extension component so that the inner support plate 15 abuts against the middle of the inner side of the piston cup. The outer support plate 12 pushes the piston cup into the piston cup groove, and the inner support plate 15 pushes the piston cup away from the outer support plate 12 and pushes it into the piston cup groove, thereby completing the assembly operation of the brake master cylinder and the piston cup.

[0031] Example 2:

[0032] Based on Embodiment 1, an electromagnet 7 and a magnetic sheet 8 are also disclosed. Please refer to [reference needed]. Figure 1 - Figure 3 As shown, its specific structure is as follows: The top of the base plate 1 is symmetrically provided with a horizontal groove 2, an electric push rod 3 is installed in the horizontal groove 2, and a positioning frame 4 is fixed at the end of the electric push rod 3. The positioning frame 4 slides in contact with the horizontal groove 2. The positioning frame 4 is set as an "L" shaped structure when viewed from the front. The top of the positioning frame 4 is set as an arc-shaped structure. The top of the positioning frame 4 is slidably connected to a contact rod 5 through a spring 6. An electromagnet 7 is installed on the inner wall where the contact rod 5 is located. The electromagnet 7 and the magnetic sheet 8 are arranged opposite to each other. The magnetic sheet 8 is fixed to the front and rear sides of the contact rod 5.

[0033] When positioning different sizes of brake master cylinders, the electric push rod 3 pushes the positioning frame 4 to slide in the transverse groove 2. The positioning frame 4 contacts the outside of the brake master cylinder. Then, the abutment rod 5 on the positioning frame 4 slides on the positioning frame 4 and compresses the spring 6. At this time, the electromagnet 7 is de-energized, so it can fit more closely to the outside of the brake master cylinder, thereby maintaining the effective contact area with the brake master cylinder. After clamping and fixing, the electromagnet 7 is energized, and the magnetic sheet 8 is attracted and fixed to the electromagnet 7, making the positioning more stable.

[0034] Example 3:

[0035] Based on Embodiment 2, a guide groove 19 and a limiting groove 20 are also disclosed. Please refer to [reference needed]. Figure 4 - Figure 5As shown, its specific structure is as follows: The adjusting component includes an inner cavity 16 opened inside the mounting plate 11. A motor 17 is installed on the top of the inner cavity 16. The output end of the motor 17 is connected to a turntable 18.

The outer support plate 12 forms a horizontal sliding structure through the guide groove 19 and the limiting groove 20. The bottom of the outer support plate 12 is set as a sliding structure.

[0036] In use, for different sizes of diaphragm cups, the motor 17 inside the mounting plate 11 is started. The motor 17 drives the turntable 18 to rotate, and the turntable 18 drives the guide groove 19 to rotate accordingly. The guide groove 19 drives the outer support plate 12 to move accordingly. When the outer support plate 12 moves, it is limited by the limiting groove 20, which causes the outer support plate 12 to open and close and slide. The outer support plate 12 supports and fixes the edge of the diaphragm cup and is placed at the entrance of the brake master cylinder diaphragm cup groove.

[0037] Example 4:

[0038] Based on Embodiment 3, sleeve 23 and sleeve rod 25 are also disclosed. Please refer to [reference needed]. Figure 4 - Figure 6 As shown, its specific structure is as follows: The adjusting component includes a piston plate 21 fixed to the side of the outer support plate 12. The piston plate 21 is slidably connected to the oil cavity 22. The oil cavity 22 is correspondingly opened on the bottom inner side of the mounting plate 11. The inside of the oil cavity 22 is connected to the inside of the sleeve 23 through a connecting pipe. The sleeve 23 is fixed on the inner wall of the slide groove 24. The slide groove 24 is opened at the bottom of the circular plate 14 at equal angles. A sleeve rod 25 is slidably connected in the sleeve 23.

[0039] When in use, the outer support plate 12 moves, which drives the piston plate 21 to slide synchronously in the oil chamber 22, thereby transporting the oil in the oil chamber 22 to the sleeve 23. The oil injected into the sleeve 23 will push the sleeve rod 25 to slide. After the sleeve rod 25 slides, it drives the inner support plate 15 to move, thereby contacting the inside of the piston cup. The second cylinder 13 drives the inner support plate 15 to move down, pushing the piston cup into the piston cup groove of the brake master cylinder, thus completing the assembly work. The operation is convenient and fast, and has good adaptability.
