Abstract
Description
Technical Field
[0001] This utility model relates to the field of piston assembly technology, and in particular to an assembly auxiliary device for a motorcycle piston upper pump. Background Technology
[0002] The upper piston pump of a motorcycle is the core control component of the motorcycle hydraulic braking system. It is responsible for converting the rider's lever operation force into hydraulic pressure, which drives the lower pump to clamp the brake disc to achieve braking.
[0003] Patent CN216503315U discloses a piston assembly device for a six-sided top press. It includes a track trolley, a gantry, and a cross slide. The gantry contains a track for the track trolley, and the top of the track trolley is equipped with a cross slide adjustable in the X and Y directions. A vertical telescopic cylinder is mounted on the top of the gantry, with its telescopic rod extending through the top of the gantry. Using this patent, the piston chamber and cylinder are aligned coaxially via the cross slide, and then the telescopic cylinder is activated to push the piston into the piston chamber. However, the telescopic cylinder in this prior art lacks a pressure detection function, leading to situations where the applied pressure is too high or too low during assembly. Excessive pressure can damage the telescopic cylinder and cause piston deformation, while insufficient pressure prevents the piston from fully entering the cylinder, resulting in incomplete assembly.
[0004] Therefore, there is a need to provide an assembly auxiliary device for a motorcycle piston pump with pressure detection function. Utility Model Content
[0005] To overcome the shortcomings of existing patents where the telescopic cylinder lacks pressure detection, resulting in situations where excessive or insufficient pressure is applied during assembly, excessive pressure can easily damage the telescopic cylinder and cause piston deformation and damage, while insufficient pressure can prevent the piston from being fully pushed into the cylinder, leading to incomplete assembly, this utility model provides an assembly auxiliary device for a motorcycle piston pump with pressure detection function.
[0006] To address the aforementioned issues, this utility model employs the following technical solution: an assembly auxiliary device for a motorcycle piston pump, comprising an assembly platform, a cylinder, and a pressure plate. The cylinder is mounted on the assembly platform, and the pressure plate is mounted on the cylinder's telescopic rod. The device also includes a pressure detector and two warning devices. The pressure detector is mounted on the assembly platform, and two warning devices are mounted on the assembly platform, with the warning devices electrically connected to the pressure detector.
[0007] As an improvement to the above solution, it also includes a fixed base, a screw, a dual-axis motor, a slide, a first magnetic plate, a second magnetic plate, and a positioning plate. The fixed base is fixedly connected inside the assembly table. The dual-axis motor is mounted on the fixed base. Screws are mounted on the two output shafts of the dual-axis motor through couplings. A slide is threaded on the screw. The first magnetic plate is embedded in the slide. The second magnetic plate is attracted to the first magnetic plate. The positioning plate is set on the second magnetic plate.
[0008] As an improvement to the above solution, it also includes mounting blocks, mounting seats, sliding rods, locking blocks, and elastic elements. Two mounting blocks are fixedly connected to the positioning plate, and a mounting seat is fixedly connected to the sliding seat. Two sliding rods are slidably arranged on the mounting seat, and locking blocks are fixedly connected to the sliding rods. The locking blocks are inserted into adjacent mounting blocks, and elastic elements are sleeved on the sliding rods. The two ends of the elastic elements are connected to the locking blocks and the mounting seats, respectively.
[0009] As an improvement to the above solution, it also includes limit plates, with four limit plates fixedly connected to the assembly table.
[0010] As an improvement to the above solution, two guide rods are fixedly connected to the pressure plate.
[0011] As an improvement to the above solution, four feet are fixedly connected to the assembly platform.
[0012] Compared with the prior art, the present invention has the following technical effects: 1. The pressure detector monitors the pressing force of the cylinder in real time. When the pressure exceeds or falls below the set threshold, the control module in the pressure detector triggers the alarm, which illuminates and sounds an alarm, reminding the operator to adjust the pressure and check the assembly status, ensuring assembly quality and preventing the cylinder from being damaged due to overload.
[0013] 2. By starting the dual-axis motor, the two output shafts of the dual-axis motor drive the two screws to rotate, causing the slide to move laterally along the screws. The slide drives the first magnetic plate, the second magnetic plate, and the positioning plate to move. The two positioning plates move synchronously, thereby pushing the cylinder body to the center, thus ensuring that the cylinder body is located under the pressure plate, ensuring assembly quality and efficiency.
[0014] 3. By re-clamping the mounting block on the corresponding specification positioning plate into the slide block and aligning the clamping block with the mounting block, and then releasing the slide rod, the elastic element rebounds and moves the clamping block and slide rod outward, so that the clamping block is re-clamped into the mounting block. This allows for the replacement of positioning plates of different specifications and locks the positioning plate to prevent it from shifting or loosening during use. Attached Figure Description

[0021] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.
[0022] Example 1: An assembly auxiliary device for a motorcycle piston pump, see reference. Figures 1-5 As shown, the assembly includes an assembly platform 1, a cylinder 2, and a pressure plate 3. The cylinder 2 is bolted to the top of the assembly platform 1, and the pressure plate 3 is mounted on the telescopic rod of the cylinder 2. The assembly also includes a pressure detector 17 and an alarm 18. The pressure detector 17 is bolted to the assembly platform 1. The pressure detector 17 is located in front of the cylinder 2 and is electrically connected to the cylinder 2. The pressure detector 17 contains a control module. The alarms 18 are bolted to the left and right sides of the top of the assembly platform 1 and are electrically connected to the pressure detector 17.
[0023] See Figures 1-5 As shown, two guide rods are fixedly connected to the top of the pressure plate 3, and the guide rods slide on the assembly table 1.
[0024] See Figures 1-5 As shown, the bottom left and right sides of the assembly table 1 are symmetrically fixed with foot pads.
[0025] When assembling the piston, the cylinder body is placed on the assembly table 1, and the piston is placed on the cylinder body. Then, the cylinder 2 is activated. The extension rod of the cylinder 2 extends and drives the pressure plate 3 to move downward, thereby pressing the piston and components such as the upper pump. At the same time, the pressure detector 17 monitors the pressing force of the cylinder 2 in real time. When the pressure exceeds or falls below the set threshold, the control module in the pressure detector 17 triggers the alarm 18, causing the alarm 18 to light up and sound an alarm, reminding the operator to adjust the pressure and check the assembly status to ensure assembly quality and prevent the cylinder 2 from being damaged due to overload.
[0026] Example 2: Based on Example 1, refer to Figures 1-5 As shown, it also includes a fixed base 4, a screw 5, a dual-axis motor 6, a slide 7, a first magnetic suction plate 8, a second magnetic suction plate 9, and a positioning plate 10. The fixed base 4 is welded to the center of the assembly table 1. The dual-axis motor 6 is bolted to the fixed base 4. The two output shafts of the dual-axis motor 6 are each connected to a screw 5 via a coupling. The slide 7 is threaded onto the screw 5. The first magnetic suction plate 8 is embedded in the slide 7. The second magnetic suction plate 9 is attracted to the inside of the first magnetic suction plate 8. The positioning plate 10 is provided on the second magnetic suction plate 9.
[0027] When the cylinder body is placed on the assembly table 1, the dual-axis motor 6 is started. The two output shafts of the dual-axis motor 6 drive the two screws 5 to rotate, causing the slide 7 to move laterally along the screws 5. The slide 7 drives the first magnetic plate 8, the second magnetic plate 9, and the positioning plate 10 to move. The two positioning plates 10 move synchronously, thereby pushing the cylinder body to the center, thus ensuring that the cylinder body is located below the pressure plate 3, ensuring assembly quality and efficiency. Moreover, the first magnetic plate 8 and the second magnetic plate 9 are magnetically attracted, allowing the positioning plate 10 to be quickly installed and removed, which is convenient to adapt to the assembly requirements of piston pumps of different specifications.
[0028] See Figure 1 and Figure 4 As shown, it also includes mounting blocks 12, mounting bases 13, sliding rods 14, locking blocks 15, and elastic elements 16. Mounting blocks 12 are symmetrically welded to the outer side of the positioning plate 10. The mounting blocks 12 are inserted into the sliding base 7. The mounting base 13 is fixedly connected to the outer side of the sliding base 7. The sliding rods 14 are slidably mounted on both the front and rear parts of the mounting base 13. The locking blocks 15 are fixedly connected to the outer ends of the sliding rods 14. The locking blocks 15 are inserted into the adjacent mounting blocks 12. The elastic elements 16 are sleeved on the sliding rods 14. The two ends of the elastic elements 16 are connected to the locking blocks 15 and the mounting base 13, respectively.
[0029] See Figures 1-5 As shown, it also includes a limiting plate 11. Two limiting plates 11 are fixedly connected to both the left and right sides of the assembly table 1. The limiting plates 11 are located outside the adjacent positioning plates 10.
[0030] When the positioning plate 10 needs to be replaced, pull the slide rod 14 inward. The slide rod 14 drives the locking block 15 to move outward, and the elastic element 16 is compressed accordingly, causing the locking block 15 to disengage from the mounting block 12. Then, remove the positioning plate 10, allowing the positioning plate 10 to drive the mounting block 12 to disengage from the slide base 7. At the same time, the first magnetic suction plate 8 and the second magnetic suction plate 9 disengage. Then, re-insert the mounting block 12 on the positioning plate 10 of the corresponding specification into the slide base 7, aligning the locking block 15 with the mounting block 12. Then, release the slide rod 14, and the elastic element 16 will rebound, causing the locking block 15 and the slide rod 14 to move outward, allowing the locking block 15 to re-insert into the mounting block 12. The first magnetic suction plate 8 and the second magnetic suction plate 9 will then be attracted. This allows for the replacement of positioning plates 10 of different specifications and also locks the positioning plate 10 to prevent it from shifting or loosening during use.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
