Technical Field

[0001] The invention relates to the technical field of rubber cup trimming, in particular to a rubber cup trimming and disengaging device. Background Art

[0002] Rubber cups are often used as seals to prevent liquids, gases, dust and other substances from entering or leaking. In hydraulic and pneumatic systems, rubber cups can effectively seal joints and maintain the working pressure and stability of the system. During the manufacturing process, dimensional deviations or irregular shapes may occur, so trimming is required to remove excess material to ensure that the shape of the cup meets the design requirements and can accurately fit with other parts. Among them, in the conventional trimming method of conventional rubber cups, the tool is directly inserted into the area of ​​the rubber cup to be trimmed, and then the rubber cup is controlled to rotate to achieve trimming of the top edge. However, due to the fixed contact angle between the tool and the surface of the cup, some areas may be subjected to excessive force, affecting the uniformity of cutting and making the cup prone to damage or tearing. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a rubber cup trimming and detaching device to solve the problem that the rubber cup is easily damaged when directly cross-cutting during trimming as mentioned in the background art.

[0008] A sleeve structure whose inner diameter matches the diameter of the rotating shaft is installed on one side of the trimming tool, and a through groove matching the diameter of the telescopic button is opened on the top of the sleeve structure.

[0009] Preferably, a through groove communicating with the circular portion is formed on the top of the bearing frame, and the inner diameter of the circular portion is larger than the outer diameter of the sleeve structure.

[0018] 4. The present invention uses the control bracket plate and its related structure of the electric push rod to adjust the up and down position. After the rubber cup is trimmed, the four combined limiting bowl petals can be gradually opened to form a larger gap between the side surface of the rubber cup 3, thereby facilitating subsequent transfer and taking.

[0034] Embodiment 1

[0035] When trimming a rubber cup, the tool is usually directly inserted into the area of ​​the rubber cup to be trimmed, and then the rubber cup is controlled to rotate to achieve trimming of the top edge. However, at the beginning of trimming, the direct insertion of the tool is likely to cause damage or tearing of the edge of the rubber cup, affecting the final presentation of the rubber cup, such as Figure 1-Figure 7 As shown, this embodiment proposes a rubber cup trimming and detaching device, which can effectively prevent the rubber cup from being damaged during trimming. The rubber cup trimming and detaching device comprises a workbench 1 and a rotating assembly 2 mounted on the workbench 1, a rubber cup 3 is placed on the top of the rotating assembly 2, and a pressing assembly 4 is installed on one side of the top surface of the workbench 1 for pressing the inside of the rubber cup 3 from top to bottom and cooperating with the rotating assembly 2 to rotate the rubber cup 3, as shown in FIG. Figure 1As shown, the pressing assembly 4 is basically consistent with the prior art, and is specifically composed of a hydraulic cylinder and an inner pressing block rotatably mounted at the free end of the hydraulic cylinder, and the inner pressing block is set to a size and shape that matches the inside of the rubber cup 3, and is intended to control the pressing block to be embedded in the rubber cup 3 through the telescopic operation of the hydraulic cylinder before the rubber cup is trimmed, thereby effectively avoiding deformation during the trimming process. The top surface of the workbench 1 is installed with a shaping assembly 5 for wrapping and limiting the outer side of the rubber cup 3 after the inside of the rubber cup 3 is pressed, and the other side of the top surface of the workbench 1 is installed with a trimming assembly 6 for transitioning from oblique downward cutting to horizontal cutting. In actual application, the rubber cup 3 is stably placed at a set position on the rotating component 2, and then the pressing component 4 is operated to firmly press the rubber cup 3 on the top of the rotating component 2. After that, the shaping component 5 is operated to maintain the shape of the outer side of the rubber cup 3, thereby effectively preventing the side of the rubber cup 3 from being deformed when the rotating component 2 is subsequently operated to drive the rubber cup 3 to rotate relative to the trimming component 6.

[0036] Specifically, the trimming assembly 6 includes an electric telescopic rod 601 that is inserted upward at the bottom of the workbench 1, a supporting frame 602 is installed on the top of the electric telescopic rod 601, a trimming tool 603 is inserted into the inside of the supporting frame 602, and a slot 604 is opened on one side of the supporting frame 602 to provide an angle adjustment space for the trimming tool 603. A stepper motor 605 is installed inside the supporting frame 602 to drive the trimming tool 603 to adjust between 0°-45°, and the cutting side of the trimming tool 603 is coaxial with the center of the circle of the output end of the stepper motor 605. In accordance with the above, after the rubber cup 3 to be trimmed is fixed inside and outside by the shaping component 5 and the pressing component 4, the rotating component 2 is started to operate, and the electric telescopic rod 601 is contracted downward by a set distance, so that the trimming tool 603 is inserted downward from the top edge of the rubber cup 3 to cut obliquely, and then after the electric telescopic rod 601 is contracted, the stepper motor 605 is immediately operated to drive the trimming tool 603 to adjust from a 45° inclined state to a horizontal arrangement state, so that the subsequent cutting of the top edge of the rubber cup 3 is adjusted to a cross-cut. The trimming tool 603 first gradually contacts the top edge of the rubber cup 3, instead of directly cutting in horizontally, and then the cutting angle of the trimming tool 603 changes gradually, which makes the force transmission more uniform, avoids uneven pressure after a sudden impact, and can make the cutting process more stable, reducing the tearing or unevenness of the edge.

[0037] Embodiment 2

[0038] Following the above-mentioned embodiment 1, in order to effectively prevent the trimming tool 603 from being disconnected from the output end of the stepping motor 605 for no reason, as shown in FIG. Figure 2-Figure 3As shown, the notch 604 is composed of a rectangular part, a right-angled trapezoidal part connected to the bottom of the rectangular part, and a circular part connected to the rear of the right-angled trapezoidal part near the side of the stepper motor 605, and the maximum inclination angle of the acute angle part at the bottom of the right-angled trapezoidal part is 45°, thereby limiting the range of rotation of the trimming tool 603 driven by the stepper motor 605. The output end of the stepper motor 605 is connected to a rotating shaft 6051 located in the circular part, and a circular groove is provided at the top of the rotating shaft 6051. A telescopic button 6052 is installed inside the circular groove. The telescopic button 6052 is basically consistent with the structure in the prior art, mainly composed of a spring and a button, and is intended to adjust the position of the button up and down when it is subjected to external force and the external force is cancelled. A sleeve structure 6031 with an inner diameter matching the diameter of the rotating shaft 6051 is installed on one side of the trimming tool 603, and a through groove matching the diameter of the telescopic button 6052 is provided at the top of the sleeve structure 6031. The trimming tool 603 is connected to the rotating shaft 6051 through the sleeve structure 6031, so as to achieve the purpose of assembling the trimming tool 603 and the stepping motor 605. When the two are assembled, the trimming tool 603 is adjusted to be inclined, and one side of it is fitted with the inclined surface of the right-angle trapezoidal part. At this time, the through groove on the sleeve structure 6031 and the top of the telescopic button 6052 are in the same horizontal direction, and the sleeve structure 6031 slides from front to back along this inclined surface, so that the sleeve structure 6031 extends backward to the inside of the circular part and is gradually sleeved on the outer surface of the rotating shaft 6051. And because the top of the telescopic button 6052 is inclined near the trimming tool 603, when the sleeve structure 6031 moves along the surface of the rotating shaft 6051 toward the side of the stepping motor 605, the top of the telescopic button 6052 will first be subjected to an extrusion force, causing it to shrink downward back into the circular groove. As the through groove and the circular groove overlap each other up and down, the extrusion force on the telescopic button 6052 is cancelled, and then it returns to its original shape upward and is inserted into the interior of the through groove, thereby achieving the purpose of maintaining the assembly stability between the sleeve structure 6031 and the rotating shaft 6051.

[0039] Embodiment 3

[0040] A through slot 6021 is provided on the top of the carrier frame 602 and is connected to the circular part, and the inner diameter of the circular part is larger than the outer diameter of the sleeve structure 6031. By using a tool to press the telescopic button 6052 located in the circular part downward along the through slot 6021, so that it shrinks downward into the circular groove, and at the same time, a pulling force is applied to the trimming tool 603 away from the side of the stepping motor 605, the sleeve structure 6031 and the rotating shaft 6051 can be separated, so that the disassembly process of the trimming tool 603 is convenient and simple.

[0041] Embodiment 4

[0042] The rotating assembly 2 includes a rotating motor 201 installed at the bottom of the workbench 1. The output end of the rotating motor 201 is connected to a turntable 202 located on the workbench 1. A sensor 203 for electrical connection with the shaping assembly 5 is embedded on the top of the turntable 202. The sensor 203 preferably uses a pressure sensor. When the hydraulic cylinder in the pressing assembly 4 completely fits the inner pressing block into the rubber cup 3 placed on the top surface of the turntable 202, the sensor 203 will sense the pressure value reaching the set amount, and at this time, a signal is given to the shaping assembly 5 to start running, thereby ensuring the accuracy of the shaping assembly 5 in the running period after the pressing assembly 4.

[0043] Embodiment 5

[0044] Under normal circumstances, when the rubber cup 3 is trimmed, in order to ensure that it is not deformed, a matching limiting and shaping structure is usually required inside and outside to ensure the stability of the subsequent rubber cup 3 during trimming. However, under this premise, after the subsequent rubber cup 3 is trimmed, it is difficult to separate from the limiting and shaping structure, which takes a certain amount of time, thus affecting the overall efficiency. In order to effectively solve this problem. Figure 1 , Figure 6-Figure 7 As shown, the shaping component 5 includes four equally spaced limiting bowl petals 501 disposed on the outer side of the top of the rotating disk 202, and a protruding block 502 is installed on both the limiting bowl petal 501 and the rotating disk 202, and the two protruding blocks 502 are connected by a hinge. By dividing the shaping structure outside the rubber cup 3 to be trimmed into four foldable, merging and expandable modules, it is convenient to separate the external shaping structure from the rubber cup 3 after trimming is completed, thereby increasing the efficiency and convenience of taking out and transferring the rubber cup 3.

[0045] Specifically, a limit ring 503 is arranged around the outer side of the rotating disk 202, and a positioning ring 504 is rotatably connected to the bottom of the limit ring 503. A support plate 505 is installed at the bottom of the positioning ring 504. An electric push rod 506 is installed between the bottom of the support plate 505 and the workbench 1 for lifting the limit ring 503 from the outer side of the rotating disk 202 to the outer side of the middle of the rubber cup 3. By running the electric push rod 506, it is prompted to extend upward or contract downward accordingly, and the support plate 505 can be controlled to drive the positioning ring 504 to adjust its position up and down, so as to facilitate the change of the height of the limit ring 503 from the outer side of the rotating disk 202 to the outer side of the middle of the rubber cup 3. In the process of the limit ring 503 rising to the height of the middle of the rubber cup 3, the four limit bowl petals 501 can be transformed from the open state to the merged state and stably maintained. On the contrary, when the limiting ring 503 descends in height, the four limiting bowl petals 501 turn from being closed to being open under the action of their own gravity, so that a larger gap is formed between them and the side surface of the rubber cup 3, thereby facilitating the subsequent transfer and taking of the rubber cup 3.

[0046] More specifically, the inner wall of the limiting ring 503 is provided with an arc groove 5031, and the width of the arc groove 5031 gradually decreases from bottom to top, and the outer surface of the limiting bowl 501 is provided with an arc convex strip 5011 that matches the shape of the arc groove 5031. After the limiting ring 503 is raised to a set height position by the electric push rod 506, the arc groove 5031 can be engaged with the arc convex strip 5011 on the surface of the combined limiting bowl 501, so that when the rotating assembly 2 is subsequently operated, the limiting bowl 501 can drive the limiting ring 503 to rotate along the upper surface of the positioning ring 504, rather than the limiting bowl 501 rotating relative to the limiting ring 503, thereby avoiding wear on the surface of the limiting bowl 501.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
