Description

Technical Field

[0001] The utility model relates to the technical field of clutch circlip installation, in particular to a circlip press-fitting and detection integrated device. Background Art

[0002] As a kind of fastener, the circlip is often used in the clutch master cylinder. It is installed in the circlip groove of the piston ring to prevent axial movement of parts on the shaft.

[0003] At present, the installation of the retaining spring on the piston ring is generally achieved by using a cylinder press machine and a pressing sleeve to press the retaining spring and manually checking the retaining spring's position. Specifically, the piston ring and the retaining spring are sequentially sleeved on the pressing guide sleeve on the pressing station, and the cylinder press machine is started to drive the pressing sleeve to press down the retaining spring and the piston ring, so that the retaining spring enters the retaining spring groove on the piston ring through the pressing guide sleeve. After the retaining spring is pressed, the piston ring needs to be removed manually, and whether the retaining spring is pressed in place is checked by visual observation or touch.

[0004] However, the inspection frequency and inspection results of manual inspection of retaining springs have large errors, which can easily lead to misjudgment or missed inspections, resulting in product quality accidents. In addition, manual inspection is labor-intensive, time-consuming, and has a slow production pace, which seriously affects production efficiency. Utility Model Content

On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0027] See also Figure 1 to Figure 2 The integrated device for pressing and detecting a retaining spring of the utility model comprises a connecting seat 1, a pressing assembly 2 connected to the connecting seat, and a detecting assembly 3 arranged on one side of the pressing assembly 2. The pressing assembly 2 is used to press the retaining spring sleeved on the pressing guide sleeve on the pressing station into the retaining spring groove on the piston ring. The detecting assembly 3 is used to detect the pressing state of the pressing assembly 2 to ensure that the retaining spring is pressed into place.

[0028] As an example, the connecting seat 1 includes a first connecting plate 11, two support plates 12 symmetrically arranged on both sides of the first connecting plate 11, and a second connecting plate 13 connected to the two support plates 12. The first connecting plate 11, the two support plates 12 and the second connecting plate 13 together form a accommodating space, and a press-fit component 2 is provided in the accommodating space.

[0029] Furthermore, the press-fitting assembly 2 includes a press rod 21 and a press sleeve 22 connected to the press rod 21, and one end of the press sleeve 22 away from the press rod 21 passes through the bottom of the connecting seat 1. The press sleeve 22 is located in the accommodating space of the connecting seat 1, and the press sleeve 22 is a hollow structure. In other words, the press sleeve 22 is provided with a press-fitting through hole for the press-fitting guide sleeve to enter, and the cross-section of the press-fitting through hole is circular, so that the press sleeve 22 can press down the retaining spring on the press-fitting guide sleeve. Specifically, the press sleeve 22 includes a connecting portion 221 and a press-fitting portion 222, the connecting portion 221 is connected to one end of the press rod 21, and the other end of the press rod 21 passes through the second connecting plate 13, and the circumferential side surface of the connecting portion 221 is provided with a gap groove 23 along the circumferential direction, and the gap groove 23 is used to cooperate with the detection assembly 3 to realize the detection of the press-fitting state of the press sleeve 22 by the detection assembly 3. As a specific example, in this embodiment, the connecting portion 221 is cylindrical, the pressing portion 222 is truncated cone-shaped, and the diameter of the cross section of the pressing end surface of the pressing portion 222 is smaller than the cross section diameter of the connecting portion 221 .

[0030] Further, the press-fitting portion 222 is located on the side of the first connecting plate 11 away from the second connecting plate 13, and a limiting ring 14 is provided on the first connecting plate 11, and the limiting ring 14 is sleeved on the circumferential surface of the press-fitting portion 222. As a specific example, in this embodiment, a mounting through hole is provided on the first connecting plate 11, and the side of the first connecting plate 11 away from the second connecting plate 13 is fixedly connected to the limiting ring 14 by a plurality of bolts, and the limiting ring 14 is provided with a limiting through hole adapted to the circumferential surface of the press-fitting portion 222, and the limiting through hole is connected to the mounting through hole on the first connecting plate 11, and the press-fitting portion 222 passes through the mounting through hole and the limiting through hole in sequence, and finally the press-fitting end surface of the press-fitting portion 222 is exposed outside the limiting ring 14.

[0031] It should be noted that, since a pressing rod 21 is connected to the upper part of the pressing sleeve 22, when the pressing end face of the pressing part 222 is exposed outside the limiting ring 14, the circumferential surface of the pressing part 222 does not abut against the inner wall of the limiting ring 14, and there is a certain gap between the two, so that the pressing rod 21 can drive the pressing sleeve 22 to move down a certain distance to further complete the pressing process of the pressing sleeve 22 on the retaining spring on the pressing guide sleeve. During this process, the position of the gap groove 23 on the pressing sleeve 22 will change accordingly, and the detection component 3 can know the press-fitting status of the retaining spring based on the change in the position of the gap groove 23.

[0032] As an example, the detection assembly 3 includes a mounting plate 31 and a detection plate 32 connected to the mounting plate 31, the mounting plate 31 is connected to the connecting seat 1, the mounting plate 31 includes a first side plate 311 and a second side plate 312 connected to the first side plate 311. In the present embodiment, the mounting plate 31 is an L-shaped plate, the end of the first side plate 311 away from the second side plate 312 is provided with a bolt through hole and is fixedly connected to the second connecting plate 13 by bolts, and the side of the second side plate 312 facing away from the first side plate 311 is fixedly connected with the detection plate 32.

[0033] Furthermore, the detection board 32 includes a fixing portion 321 and an optical fiber transmitting portion 322 and an optical fiber receiving portion 323 provided at both ends of the fixing portion 321, and the optical fiber transmitting portion 322 and the optical fiber receiving portion 323 are provided opposite to each other, and the detection board 32 is connected to the second side plate 312 through the fixing portion 321, and the optical fiber emitted by the optical fiber transmitting portion 322 is received by the optical fiber receiving portion 323. In the present embodiment, the detection board 32 is a U-shaped plate, and the optical fiber transmitting portion 322 and the optical fiber receiving portion 323 are provided at two opposite sides of the U-shaped plate, respectively, and the opening of the U-shaped plate is provided in the direction where the pressing sleeve 22 is located, and one side of the pressing sleeve 22 provided with the gap groove 23 is provided in the opening of the U-shaped plate, so that the gap groove 23 can pass the optical fiber emitted by the optical fiber transmitting portion 322, thereby realizing the detection of the pressing state of the pressing assembly 2 by the detection component 3. It should be noted that the plane where the gap groove 23 is located is higher than the plane where the optical fiber emitted by the optical fiber transmitting part 322 is located. When the pressing sleeve 22 moves downward under the drive of the pressing rod 21, the gap groove 23 will move downward to the plane where the optical fiber is located, so that the optical fiber emitted by the optical fiber transmitting part 322 can be transmitted to the optical fiber receiving part 323 through the gap groove 23, and the reflection state between the optical fiber transmitting part 322 and the optical fiber receiving part 323 will change from a closed circuit to a through circuit state.

[0034] Furthermore, the slot width of the gap slot 23 on the pressing sleeve 2 is greater than the spot diameter of the optical fiber emitted by the optical fiber emitting portion 322, and the slot width of the gap slot 23 is 0.2 mm-0.4 mm. As a specific example, in this embodiment, the spot diameter of the optical fiber emitted by the optical fiber emitting portion 322 is 0.2 mm, and the slot width of the gap slot 23 is 0.3 mm.

[0035] Furthermore, the integrated device for pressing and detecting the retaining spring of the utility model also includes a proximity switch detector 4, which is arranged on one side of the second connecting plate 13. The proximity switch detector 4 is used to receive a start signal to start the cylinder pressing machine to press down and receive a reset signal to reset the cylinder pressing machine.

[0036] In actual use, the use principle of the integrated device for press-fitting and detecting the retaining spring of the utility model is as follows: a connecting seat 1 is provided just above the press-fitting station, a cylinder press is connected to the connecting seat 1, a press-fitting guide sleeve is provided on the press-fitting station, an IC piston ring and a retaining spring matched with the retaining spring groove on the IC piston ring are sequentially mounted on the press-fitting guide sleeve, and then the press-fitting station lifts the above workpiece to be press-fitted to a preset press-fitting position. When the workpiece to be press-fitted reaches the preset press-fitting position, that is, when the workpiece to be press-fitted is in place, the proximity switch detector 4 receives The starting signal is sent, the cylinder press starts and drives the connecting seat 1 to move downward, and the press-fitting guide sleeve gradually enters the press-fitting through hole of the press sleeve 22. The press-fitting end face of the press sleeve 22 first contacts the retaining spring, and pushes the retaining spring and the IC piston ring to gradually move downward along the press-fitting guide sleeve. When the bottom of the IC piston ring is in contact with other workpieces, that is, the position of the IC piston ring is restricted and cannot move downward any further, the pressing rod 21 starts and drives the press sleeve 22 to move downward again, pushing the retaining spring again, so that the retaining spring is pressed into the retaining spring groove on the IC piston ring.

[0037] It should be noted that, when the cylinder press machine drives the connection seat 1 to move downward, the optical fiber emitted by the optical fiber transmitting part 322 on the detection plate 32 is blocked by the side of the pressing sleeve 22 and cannot be received by the optical fiber receiving part 323, that is, the optical fiber transmitting part 322 and the optical fiber receiving part 323 are in a closed circuit state. When the pressing sleeve 22 moves down a preset distance under the action of the pressing rod 21, the gap groove 23 moves down and is located between the optical fiber transmitting part 322 and the optical fiber receiving part 323. At this time, the optical fiber emitted by the optical fiber transmitting part 322 is transmitted to the optical fiber receiving part 323 through the gap groove 23 for reception, that is, the optical fiber transmitting part 322 and the optical fiber receiving part 323 become a passage state, indicating that the retaining spring is pressed into place. At the same time, the proximity switch detector 4 detects that the connection seat 1 is in place, confirms that the pressing is completed again, and the cylinder press machine drives the connection seat 1 to move up and back to its original position. If the gap groove 23 is not between the optical fiber transmitting part 322 and the optical fiber receiving part 323 after the pressing sleeve 22 moves down a preset distance under the action of the pressing rod 21, the optical fiber emitted by the optical fiber transmitting part 322 is blocked by the side of the pressing sleeve 22 and cannot be received by the optical fiber receiving part 323, that is, the optical fiber transmitting part 322 and the optical fiber receiving part 323 are still in a closed circuit state, then the retaining spring is in an abnormal state and is not pressed into place. At this time, the detection board 3 will send out an alarm signal to prompt the operator to check the workpiece.

[0038] In summary, the beneficial effect of the integrated device for pressing and detecting the retaining spring of the utility model is that by adding a detection component on one side of the press-fitting component, real-time monitoring of the state of the press-fitted retaining spring of the press-fitting component can be achieved, and the press-fitting of the retaining spring in place can be ensured without manual inspection. The detection of the retaining spring in place state is more accurate, which improves the detection efficiency, and the pressing and detection are carried out simultaneously, which saves labor and improves production efficiency.
