Description

Technical Field

[0001] The present application relates to the field of automobile parts assembly, and in particular to a leather cup assembly tool. Background Art

[0002] Compared to traditional center valve or oil return hole-type brake master cylinders, plunger-type brake master cylinders have the advantages of smaller size, lighter weight, and fewer parts. However, they face the challenge of difficult assembly of the rubber cup inside the cylinder body. Specifically, the diameter of the rubber cup is larger than the diameter of the main hole inside the cylinder body, making it difficult to install the rubber cup inside the cylinder body. Moreover, the rubber cup groove for mounting the rubber cup is located deep inside the cylinder body, further increasing the difficulty of rubber cup assembly.

[0003] Existing cup assembly facilities are mainly divided into manual and fully automatic types, but both have their own shortcomings.

[0004] The manual cup assembly device is a simple manual assembly tool. During use, the cup is fixed into a specific shape using the tool and then positioned within the cup groove inside the cylinder. The tool is then released, allowing the cup to retract into the groove due to its inherent springback properties, completing the assembly. This manual assembly tool is cumbersome and inefficient to operate. Furthermore, assembly relies entirely on the operator's experience and skills, making assembly accuracy difficult to guarantee and error-proofing capabilities insufficient, making it impossible to guarantee product quality and output.

[0005] The fully automatic leather cup assembly facility is a fully automated leather cup assembly equipment that uses fully automated equipment such as robotic arms and high-definition cameras. Although it has high assembly efficiency and high assembly precision, it is expensive, has general versatility (fully automated equipment is generally suitable for platform products), and has high management costs. This will bring higher economic and management pressures to the company and is not suitable for use by some small and medium-sized enterprises. Utility Model Content

[0036] Figure 1 This is a structural diagram of a leather cup assembly tool 100 provided in an embodiment of the present application, as shown in FIG. Figure 1 As shown, the embodiment of the present application provides a leather cup assembly tool 100, which includes a mounting seat assembly 10, a push rod lifting assembly 20, and a core shaft lifting and rotating assembly 30. Each part is described in detail below.

[0037] The mounting base assembly 10 is used to mount a cylinder body. In the embodiment of the present application, the cylinder body of a plunger master cylinder is used as an example for illustration. The mounting base assembly 10 includes a base 11 , a guide sleeve 12 , and a pad 13 .

[0038] The base 11 serves as a mounting foundation for the guide sleeve 12 and the spacer block 13 .

[0039] The guide sleeve 12 is vertically mounted on the top of the base 11. The guide sleeve 12 is used to cooperate with the main hole of the cylinder body for the cylinder body to be installed. The guide sleeve 12 also guides the lifting and lowering of the ejector rod 21 installed inside it. The two ends of the guide sleeve 12 are through-holes for the ejector rod 21 to pass through and enable the leather cup to be installed into the guide sleeve 12 from the top.

[0040] Regarding the connection structure between the guide sleeve 12 and the base 11, as an example, a first boss 121 is provided on the outer wall of the lower end of the guide sleeve 12, extending radially outward. This first boss 121 is embedded and fixed in a slot defined at the top of the base 11. Furthermore, a plurality of first connection holes (not shown) may be provided on the first boss 121 and at the bottom of the slot, corresponding to each other. The first boss 121 can then be connected to the base 11 via fasteners, ensuring a secure connection.

[0041] The pad 13 is provided on the top of the base 11 and is sleeved on the outside of the guide sleeve 12. The pad 13 is used to raise the cylinder body. The pad 13 is replaceable, and the installation height of the cylinder body can be adjusted by replacing pads 13 of different heights. The reason for adjusting the installation height of the cylinder body is that the height positions of the leather cup grooves inside the cylinder bodies of different plunger master cylinders are different. In the process of assembling the cylinder body and the leather cup using the present leather cup assembly tool 100, it is necessary to make the lower end face of the leather cup groove and the upper end face of the guide sleeve 12 at the same horizontal plane for the subsequent assembly of the leather cup. Therefore, the pad 13 is provided. By replacing pads 13 of different heights, the plunger master cylinder bodies of the same cylinder diameter with different leather cup groove height positions can share the same set of tooling for assembling the leather cup, making the present leather cup assembly tool 100 highly versatile.

[0042] The push rod lifting assembly 20 is used to press down, fix, and lift the leather cup on the leather cup assembly tool 100. The push rod lifting assembly 20 includes a push rod 21 and a first lifting drive 22. The push rod 21 is installed in the guide sleeve 12 and cooperates with the guide sleeve 12 for guidance. The push rod 21 is a hollow structure with both ends through. The interior of the push rod 21 is used to install the core shaft 31, and the push rod 21 plays a guiding role in the lifting and lowering of the core shaft 31. The first lifting drive 22 is connected to the lower end of the push rod 21 and is used to drive the push rod 21 to rise and fall.

[0043] Regarding the connection structure between the push rod 21 and the first lifting drive member 22, as an example, the lower end of the push rod 21 is provided with a second boss 211 protruding radially outward, the first lifting drive member 22 is installed inside the base 11, the first lifting drive member 22 is a first cylinder and the output end of the first cylinder is vertically upward, the first cylinder can be a double-rod cylinder, and the output end of the first cylinder and the second boss 211 are correspondingly provided with a plurality of second connecting holes (not shown in the figure), so that the output end of the first cylinder can be connected to the second boss 211 through a fastener, thereby realizing the connection between the first lifting drive member 22 and the push rod 21. Furthermore, a through hole can be provided in the middle of the output end of the first cylinder, which can facilitate the arrangement of the core shaft lifting and rotating assembly 30, making the structure more compact.

[0044] Among them, when the first lifting drive member 22 drives the push rod 21 to descend into place, the upper end surface of the push rod 21 is lower than the upper end surface of the guide sleeve 12, so that a leather cup installation space 122 for the leather cup to be installed is formed between the upper end surface of the push rod 21 and the upper end surface of the guide sleeve 12.

[0045] The spindle lifting and rotating assembly 30 is used to achieve the assembly of the leather cup 1 in the cylinder 2 by coordinating the lifting and rotating action of the spindle 31 with the lifting action of the ejector rod 21. The spindle lifting and rotating assembly 30 includes a spindle 31, a rotary drive member 32, and a second lifting drive member 33.

[0046] The core shaft 31 is installed in the push rod 21, and the core shaft 31 includes an end section 311, a leather cup installation section 312, and a main shaft section 313 which are arranged in sequence from top to bottom.

[0047] The end section 311 is located outside the upper end of the push rod 21 and the upper end of the guide sleeve 12. The shape of the end section 311 is designed to facilitate insertion into the cylinder body 2. For example, the end section 311 is a truncated cone-shaped structure with a small upper end and a large lower end. The lower end of the end section 311 is slightly larger than the inner diameter of the guide sleeve 12, so that when the core shaft 31 descends, the lower end of the end section 311 is blocked by the upper end of the guide sleeve 12.

[0048] The cup mounting section 312 extends beyond the upper end of the push rod 21 and is adapted to fit over the cup 1. It should be noted that when the cup is fitted onto the cup mounting section 312 via the end section 311 and installed within the cup mounting space 122, the cup's circumference is wrapped by the guide sleeve 12, resulting in a compressed, folded state with a portion of the structure laterally concave. Therefore, the outer surface of the cup mounting section 312 can be provided with a groove 3121 to accommodate the laterally concave structure of the cup when located within the cup mounting space 122. This groove 3121 can give the cup mounting section 312 a C-shaped cross-section.

[0049] The main shaft section 313 is disposed in the push rod 21 and is guided and matched with the push rod 21 .

[0050] The rotary drive member 32 is connected to the lower end of the main shaft section 313, and the rotary drive member 32 is used to drive the core shaft 31 to rotate and expand the compressed leather cup 1. The second lifting drive member 33 is connected to the rotary drive member 32, and the second lifting drive member 33 is used to drive the core shaft 31 and the rotary drive member 32 to rise and fall together.

[0051] Regarding the rotating drive member 32 and the second lifting drive member 33, as an example, the rotating drive member 32 and the second lifting drive member 33 are both arranged inside the base 11; the rotating drive member 32 is a motor, which is arranged at the output end of the first cylinder and the lower end of the push rod 21, and the output shaft of the motor is vertically upward and connected to the lower end of the main shaft section 313 of the core shaft 31; the second lifting drive member 33 is a second cylinder, the cylinder body of the second cylinder is installed at the upper end of the cylinder body of the first cylinder, and the output end of the second cylinder is vertically upward and connected to the motor.

[0052] The leather cup assembly tool 100 further includes a control unit, which is signal-connected to the first lifting drive member 22 , the rotation drive member 32 and the second lifting drive member 33 and is used to control the actions of the first lifting drive member 22 , the rotation drive member 32 and the second lifting drive member 33 .

[0053] The use process of the leather cup assembly tool 100 is as follows: in the initial state, Figure 2 As shown, the opening of the core shaft 31 is a, that is, the distance from the lower end surface of the end section 311 to the upper end surface of the guide sleeve 12 is a, and for example, a is 10 mm. Figure 3 As shown, the leather cup 1 is manually put onto the leather cup installation section 312 of the core shaft 31 through the end section 311 and installed into the leather cup installation space 122, ensuring that it is pressed into place.

[0054] Then, if Figure 4 As shown, the push rod 21 remains stationary, and the core shaft 31 descends under the drive of the second lifting drive member 33. The core shaft 31 descends until the lower end surface of the end section 311 is in contact with the upper end surface of the guide sleeve 12, so that the leather cup 1 is fixed in the leather cup installation space 122.

[0055] Then, if Figure 5 and Figure 6 As shown, the cylinder body 2 of the plunger master cylinder is installed on the guide sleeve 12 and the pad 13. By replacing the pad 13 with different heights, the lower end surface of the leather cup groove 201 and the upper end surface of the guide sleeve 12 are at the same horizontal plane for subsequent assembly of the leather cup 1.

[0056] Then, if Figure 6 and Figure 7As shown, the core shaft 31 is driven by the second lifting drive member 33 to rise to expose the leather cup groove 201 and ensure that the leather cup 1 can be normally ejected from the leather cup installation space 122 by the ejector rod 21. At this time, the opening of the core shaft 31 is b, that is, the distance between the lower end surface of the end section 311 and the upper end surface of the guide sleeve 12 is b, and illustratively, b is 5 mm.

[0057] Afterwards, the push rod 21 is driven upward by the first lifting drive member 22, and the push rod 21 gently pushes the leather cup 1 out of the leather cup installation space 122 to the leather cup groove 201. At this time, the outer side of the leather cup 1 is not wrapped by the guide sleeve 12, and the leather cup 1 is inserted into the leather cup groove 201 under the elastic restoring force of its own rubber.

[0058] In order to ensure that the leather cup 1 is completely inserted into the leather cup groove 201, the core shaft 31 is rotated under the driving force of the rotary drive member 32 to expand the compressed leather cup 1, especially the side concave structure of the leather cup 1 when it is located in the leather cup installation space 122, to restore the original shape. For example, the core shaft 31 rotates one circle under the driving force of the rotary drive member 32. After the core shaft 31 rotates, as shown in FIG. Figure 8 As shown, the push rod 21 is further raised under the drive of the first lifting drive member 22 until its upper end surface contacts the lower end surface of the end section 311 of the core shaft 31. For example, the push rod 21 is raised another 5 mm. The raised push rod 21 pushes the leather cup 1 laterally and outward from the inner side of the leather cup 1, so that the leather cup 1 is completely accommodated in the leather cup groove 201.

[0059] After the above operations are completed, the cylinder body 2 of the plunger master cylinder with the leather cup 1 installed is removed, and then the various components of the leather cup assembly tool 100 are reset to the initial state, and the next assembly operation can be carried out.

[0060] In summary, the leather cup assembly tool provided in the embodiment of the present application can ensure that the leather cup is fully assembled in the cylinder body of the plunger master cylinder through the lifting action of the push rod, in coordination with the lifting and rotating actions of the core shaft, thereby avoiding the occurrence of equipment jamming due to damage to the leather cup or improper assembly; compared with manual assembly tooling, the automation level of this tooling is higher, which ensures the assembly accuracy and efficiency of the product and can meet the needs of mass production; compared with fully automated leather cup assembly equipment, the production and manufacturing costs and management costs of this tooling are lower, and it is more suitable for production and use by small and medium-sized enterprises.

[0061] The above is only a specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the field can easily think of various changes or replacements within the technical scope disclosed in the present application, which should all be included in the scope of protection of the present application.
