Description

Technical Field

[0001] This utility model relates to the field of shift fork retaining ring error detection technology, specifically a shift fork retaining ring multi-station error detection machine. Background Technology

[0002] A shift fork retaining ring specifically refers to a retaining ring installed on the shift fork shaft or shift fork body. It is used to limit the axial movement range of the shift fork and prevent it from coming off or displacing excessively during operation. In order to prevent the shift fork retaining ring from affecting its normal use due to quality problems, it is usually necessary to test it after the shift fork retaining ring is manufactured.

[0003] A Chinese patent with publication number CN218349362U discloses a fixture for testing the accuracy of retaining rings, relating to the field of retaining rings. The fixture includes a base plate with a limiting mechanism on its upper surface. A vertical plate is vertically mounted near one side of the upper surface of the base plate. A vertical groove is formed through the outer side of the vertical plate, and a connecting plate is installed inside the groove. An electric telescopic rod is installed between the upper surface of the connecting plate and the top of the groove. A measuring scale is mounted at one end of the connecting plate. Auxiliary mechanisms are provided between the upper surface of the base plate and both ends of the measuring scale. The limiting mechanism includes a transverse groove formed on the upper surface of the base plate. This fixture for testing the accuracy of retaining rings can effectively clamp and fix the retaining rings to the upper surface of the base plate, preventing movement that could affect subsequent accuracy testing. Furthermore, the auxiliary mechanisms prevent the measuring scale from tilting, which could lead to inaccurate measurement results.

[0004] In existing technologies, the inspection of shift fork retaining rings is aided by a measuring ruler. However, during the inspection process, the shift fork retaining ring is usually clamped and limited by an arc-shaped plate, allowing operators to inspect its quality from only one side. The ring cannot be rotated, making it easy to miss other areas and thus failing to detect quality issues. This poses a safety hazard during subsequent use. Utility Model Content

[0005] Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology in that it is impossible to detect all positions of the shift fork retaining ring during the detection process.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a multi-station error detection machine for shift fork retaining ring, including a placement plate, a side plate fixedly connected to the side wall of the placement plate, a first electric telescopic rod fixedly connected to the surface of the side plate, a rectangular plate fixedly connected to the output end of the first electric telescopic rod, two second electric telescopic rods fixedly connected to the surface of the placement plate, an arc-shaped plate fixedly connected to the output end of each of the two second electric telescopic rods, an auxiliary device provided on the lower surface of the placement plate, and an observation device provided on the side of the placement plate;

[0009] The auxiliary device includes four extension rods, all of which are fixedly connected to the lower surface of the placement plate. The ends of the four extension rods away from the placement plate are fixedly connected to a base plate. The surface of the base plate has two mounting holes. The upper surface of the base plate is rotatably connected to a multi-section rod, which is a telescopic structure. A turntable is fixedly connected to the surface of the multi-section rod. A pull plate is fixedly connected to the arc surface of the multi-section rod. A spring is fitted on the surface of the multi-section rod, and the two ends of the spring are fixedly connected to the pull plate and the turntable, respectively. Four round rods are fixedly connected to the surface of the turntable. A disc is fixedly connected to the end of the multi-section rod away from the base plate. A cross hole is opened on the surface of the disc.

[0010] After the curved plate limits the position of the shift fork retainer ring to be tested, the staff can observe and test the shift fork retainer ring. After one side of the shift fork retainer ring is tested, the staff can use the pull plate to drive the disc to slide downwards. In conjunction with the turntable, the disc on the multi-section rod can be rotated, thereby helping to adjust the placement angle of the shift fork retainer ring. Then, the pull plate is released, and the spring will drive the disc to move upwards to reset.

[0011] Furthermore, four anti-slip pads are glued to the surface of the disc, and all four anti-slip pads are made of rubber.

[0012] The anti-slip pad increases the stability of the shift fork retainer ring on the disc surface, further facilitating the adjustment of the placement angle of the shift fork retainer ring by the auxiliary device.

[0013] Furthermore, a slip ring is rotatably connected to the surface of the pull plate, and two square plates are fixedly connected to the surface of the slip ring. Anti-slip holes are opened on the surface of both discs.

[0014] When the disc is pulled down, the operator's fingers can be placed on the anti-slip holes on the surface of the two square plates, and the slip ring can slide against the arc surface of the pull plate, which increases the convenience of adjusting the multi-section rod and the disc rotation.

[0015] Furthermore, the turntable has four semi-circular holes on its arc surface, and an extension frame is fixedly connected to the surface of the base plate, with rolling balls fixedly connected to the surface of the extension frame.

[0016] When adjusting the angle of the fork retaining ring driven by the adjusting disc, it can be used in conjunction with the ball and the semi-circular hole. When it is moved to the appropriate position, the ball enters the semi-circular hole, which can limit the turntable and allow the arc plate to still slide and connect with the cross hole. The auxiliary device can still be used after replacing other fork retaining rings.

[0017] Furthermore, the observation device includes a sliding frame that is slidably connected to the side wall of the placement plate, an observation tube that is fixedly connected to the surface of the sliding frame, and a refractor that is fixedly connected to the inner wall of the observation tube.

[0018] By using a refracting mirror in conjunction with an observation tube, staff can achieve good testing without having to install the placement plate in a parallel position with themselves, which facilitates the testing process and improves the accuracy of the testing.

[0019] Furthermore, sliding plates are fixedly connected to both sides of the placement plate, and detection plates are slidably connected to the surface of the sliding plates.

[0020] When inspecting the shift fork retaining ring, the sliding test plate can be moved to the surface of the shift fork retaining ring. If there is a gap between the test plate and the shift fork retaining ring, it indicates that the shift fork retaining ring has a quality problem.

[0021] Furthermore, two long rods are fixedly connected to the upper surface of the observation tube, and a support block is fixedly connected to the end of each long rod away from the observation tube. The support block has a hollow structure and is made of silicone.

[0022] When using the observation tube, staff can place their eyes on the surface of the support block, making it easy for the pupil to align with the observation tube, thus facilitating the observation and testing process.

[0023] Compared with existing technologies, this multi-station error detection machine for shift fork retaining rings has the following advantages:

[0024] I. This utility model, through the auxiliary device, can further adjust the angle of the shift fork retaining ring after it reaches the limit position via the arc plate. Furthermore, when inspecting the same shift fork retaining ring, it is not necessary to readjust the position of the arc plate. The disc and multi-section rod facilitate feeding. By observing and inspecting the shift fork retaining ring from multiple angles, the accuracy of the inspection results is ensured, and the safety of the shift fork retaining ring during subsequent use is improved.

[0025] Second, this utility model, through the setting of the observation device, enables the staff to conveniently inspect the surface of the shift fork retaining ring by the cooperation of the observation tube and the refracting mirror, which improves the inspection efficiency and the accuracy of the inspection, and ensures the quality of the shift fork retaining ring after inspection.

[0026] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0032] 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.

[0033] like Figure 1-4 As shown, this utility model provides a technical solution: a multi-station error detection machine for shift fork retaining ring, including a placement plate 1, a side plate 2 fixedly connected to the side wall of the placement plate 1, a first electric telescopic rod 3 fixedly connected to the surface of the side plate 2, a rectangular plate 4 fixedly connected to the output end of the first electric telescopic rod 3, two second electric telescopic rods 5 fixedly connected to the surface of the placement plate 1, an arc-shaped plate 6 fixedly connected to the output end of each of the two second electric telescopic rods 5, an auxiliary device 7 provided on the lower surface of the placement plate 1, and an observation device 8 provided on the side of the placement plate 1.

[0034] In this embodiment of the utility model: the shift fork retaining ring to be tested is placed on the surface of the placement plate 1, and then the arc plate 6 and the rectangular plate 4 can be used to limit the position of the shift fork retaining ring. Then, with the help of the auxiliary device 7 and the observation device 8, the shift fork retaining ring can be observed and tested from multiple angles, ensuring the overall quality of the shift fork retaining ring.

[0035] like Figure 1 and Figure 2As shown, the auxiliary device 7 includes four extension rods 701, all of which are fixedly connected to the lower surface of the placement plate 1. A base plate 702 is fixedly connected to the end of each extension rod 701 away from the placement plate 1. Two mounting holes 703 are formed on the surface of the base plate 702. A multi-section rod 704 is rotatably connected to the upper surface of the base plate 702. The multi-section rod 704 is a telescopic structure. A turntable 705 is fixedly connected to the surface of the multi-section rod 704. A pull plate 706 is fixedly connected to the arc surface of the multi-section rod 704. A spring 707 is fitted onto the surface of the multi-section rod 704. Both ends of the spring 707 are fixedly connected to the pull plate 706 and the turntable 705, respectively. The surface of the turntable 705 is fixedly... Four round rods 713 are connected. A disc 710 is fixedly connected to one end of the multi-section rod 704 away from the base plate 702. A cross hole 711 is opened on the surface of the disc 710. After the fork retaining ring to be tested is limited by the arc plate 6, the operator can observe and test the fork retaining ring. After one side of the fork retaining ring is tested, the operator can slide the disc 710 downward by pulling the plate 706. In conjunction with the turntable 705, the disc 710 on the multi-section rod 704 can be rotated, thereby helping to adjust the placement angle of the fork retaining ring. Further releasing the pull plate 706 will cause the spring 707 to move the disc 710 upward. To achieve reset, four anti-slip pads 712 are glued to the surface of the disc 710. All four anti-slip pads 712 are made of rubber. The anti-slip pads 712 increase the stability of the shift fork retainer ring on the surface of the disc 710, further facilitating the adjustment of the shift fork retainer ring's placement angle by the auxiliary device 7. A slip ring 708 is rotatably connected to the surface of the pull plate 706. Two square plates 709 are fixedly connected to the surface of the slip ring 708. Anti-slip holes are provided on the surfaces of both discs 710. When the disc 710 is pulled downwards, the operator's fingers can be placed on the anti-slip holes on the surfaces of the two square plates 709, and the slip ring 708 can slide against the arc surface of the pull plate 706. To enhance the ease of rotational adjustment of the multi-section rod 704 and the disc 710, the arc surface of the turntable 705 is provided with four semi-circular holes 716. An extension frame 714 is fixedly connected to the surface of the base plate 702, and a ball bearing 715 is fixedly connected to the surface of the extension frame 714. When the adjustment disc 710 drives the shift fork retaining ring to adjust the angle, it can work in conjunction with the ball bearing 715 and the semi-circular holes 716. When it moves to the appropriate position, the ball bearing 715 enters the semi-circular hole 716, which can limit the turntable 705 and allow the arc plate 6 to still slide and connect with the cross hole 711. The auxiliary device 7 can still be used after replacing other shift fork retaining rings.

[0036] Working principle: Multiple base plates 702 can be fixed on the workbench with mounting holes 703, enabling multi-station inspection on the workbench surface. When inspecting the shift fork retaining ring, the retaining ring to be inspected is first placed on the placement plate 1 and the driven surface of the disc 710. Then, the second electric telescopic rod 5 and the first electric telescopic rod 3 are activated, driving the arc-shaped plate 6 and the rectangular plate 4 to limit the movement of the shift fork retaining ring. At this point, the operator can inspect the side facing them. After inspection, the operator can place their finger in the anti-slip holes on the surface of the square plate 709 and pull downwards, causing the disc 710 to slide downwards. The disc surface has an anti-slip pad. 712, which is not easy to slip and fall off from the side, allows the operator to place their finger on the surface of the round rod 713 and rotate the turntable 705 90°. When rotated to the appropriate position, the ball 715 will engage inside the semi-circular hole 716 to limit the turntable 705. At this time, the angle of the shift fork retaining ring can be adjusted. The operator can release the square plate 709, and the spring 707 will drive the disc 710 to reset, allowing the operator to perform error detection again. After the arc plate 6 and the rectangular plate 4 are fixed, subsequent shift fork retaining rings with the same design can directly pull down the disc 710 to perform the loading operation, improving the detection efficiency and eliminating the need to adjust the position of the arc plate 6 and the rectangular plate 4 multiple times.

[0037] like Figure 1 and Figure 3 as well as Figure 4 As shown, the observation device 8 includes a sliding frame 801, which is slidably connected to the side wall of the placement plate 1. An observation tube 802 is fixedly connected to the surface of the sliding frame 801, and a refractor 807 is fixedly connected to the inner wall of the observation tube 802. Through the cooperation of the refractor 807 and the observation tube 802, the operator can achieve good detection without having to install the placement plate 1 parallel to the operator, thus facilitating the detection work and improving the accuracy of the detection. Slide plates 805 are fixedly connected to both sides of the placement plate 1, and a detection plate 806 is slidably connected to the surface of the slide plates 805. This is used to detect the fork retaining ring. When the detection plate 806 can be slid to the surface of the shift fork retainer, if there is a gap between the detection plate 806 and the shift fork retainer, it indicates that the shift fork retainer has a quality problem. Two long rods 803 are fixedly connected to the upper surface of the observation tube 802. Support blocks 804 are fixedly connected to the ends of the two long rods 803 away from the observation tube 802. The support blocks 804 have a hollow structure and are made of silicone. When using the observation tube 802, the staff can place their eyes on the surface of the support blocks 804, which makes it easy for the pupil to align with the observation tube 802, thus facilitating the observation and detection work.

[0038] Working principle: When inspecting the shift fork retaining ring, the operator can place their eyes on the support block 804. When the head moves, it can simultaneously drive the observation tube 802 and the sliding frame 801 to slide on the side wall of the placement plate 1, enabling the observation of the error of the shift fork retaining ring. At the same time, during the inspection process, the sliding plate 805 can be slid to move the inspection plate 806 to the surface of the shift fork retaining ring to be inspected. When a gap appears between the shift fork retaining ring and the inspection plate 806, it indicates that there is an error in the shift fork retaining ring, which increases the convenience of the inspection work.
