Description

Technical Field

[0001] This utility model belongs to the field of mechanical automation technology, and specifically relates to a press-fitting testing device. Background Technology

[0002] The car seat adjustment assembly is a key component used to adjust the angle of a car seat, playing a vital role in improving driving comfort and safety. With technological advancements, adjusters have not only seen significant improvements in adjustment range and precision but have also been optimized in durability and ease of use. An adjustment assembly typically consists of the following basic components: a backrest connecting plate, a seat connecting plate, the adjuster itself, a handwheel or adjustment handle, and a return spring. As the core component of the adjustment assembly, the assembly process of the adjuster plays a crucial role in the overall quality of the assembly. The pressing of fasteners such as washers and retainers in the adjuster is also a critical installation process, ensuring the stability and reliability of the seat adjuster. This involves the coordinated work of components such as the pivot, cam, and push plate assembly to achieve precise adjustment of the seat back angle. In some designs, retainers are used to prevent the adjustment levers on both sides of the car seat back from slipping out. In short, washers and retainers not only affect the assembly quality of the adjuster but are also essential components for the proper functioning of the seat adjustment mechanism. Existing pressing methods are usually done manually, which is inefficient and lacks uniformity and stability. How to quickly and accurately press fasteners onto the angle adjuster to improve the installation efficiency of the angle adjustment component is a technical problem that the industry needs to solve.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided in conjunction with the appendix. Figures 1-15 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0037] This utility model proposes a press-fit testing device, particularly for the press-fit testing of fasteners in automotive seat adjusters, specifically the press-fit testing between the automotive seat adjuster and the retaining ring and washer. The device includes a frame and an operating table 1 mounted on the frame. A transmission assembly is provided on one side of the operating table 1 for transporting products. A turntable assembly 2 is mounted on the operating table, and a feeding device, a press-fitting device 6, a transfer device 7, a testing device 8, and a discharging device 9 are arranged around the turntable assembly.

[0038] The turntable assembly 2 includes a turntable and quick-change positioning fixtures evenly distributed circumferentially on the turntable. The quick-change positioning fixtures can be detachably connected to the turntable in a modular form. When different specifications of products need to be manufactured, they can be replaced as a whole. Therefore, this utility model can not only be applied to the pressing of fasteners for automotive seat adjusters shown in this embodiment, but also to the pressing of other products. The following description uses only the structure shown in this illustration as an example.

[0039] In this embodiment, the quick-change positioning fixture includes a quick-change base plate 21 fitted onto a limiting support block 27. A floating mounting plate 22 is connected to one side of the quick-change base plate 21 via a spring 26, and a guide rod is provided on the outer side of the spring 26. A center positioning 23, which mates with the center of the angle adjuster 11, is provided on the floating mounting plate 22. A guide pin 25 is connected to the other side of the quick-change base plate 21 via a guide pin support block 24. Specifically, the top of the guide pin support block 24 has a groove, and the periphery of the groove has a boss 242. The bottom cross-section of the guide pin 25 is inverted "convex" shaped. The lower end of the guide pin is mounted on the boss 242, and the inverted convex bottom extends into the groove. The lower end of the guide pin has a bevel 251. The reason for the bevel 251 is that the guide pin positioning port of the angle adjuster has a chamfer 241. In order to avoid accidentally pressing the fastener onto the chamfer when pressing the fastener, that is, to avoid unnecessary impact on the pressed product, it is necessary to cover the chamfer 241. Therefore, a bevel 251 is set at the lower end of the guide pin. The size of the bevel 251 is based on covering the chamfer 241.

[0040] In this embodiment, the assembled components are used to press both the washer and the retaining ring into the required groove of the angle adjuster. Therefore, the feeding device includes an angle adjuster feeding device 5 for feeding the angle adjuster, a retaining ring feeding device 4 placed on one side of the retaining ring feeding station on the turntable, and a washer feeding device 3 placed on one side of the washer feeding station on the turntable. A retaining ring cutting device and a retaining ring conveying device are provided on one side of the retaining ring feeding device 4; a washer cutting device and a washer conveying device are provided on one side of the washer feeding device 3.

[0041] The angle adjuster feeding device 5 includes a four-axis robot 51 and a flipping gripper cylinder 52 disposed on the four-axis robot 51. The flipping gripper cylinder 52 is connected to a gripper, and the gripper is machined with convex patterns to increase the contact friction between the gripper and the angle adjuster 11.

[0042] Both the ring feeding device 4 and the washer feeding device 3 include a corresponding vibrating plate and a vibrating material belt set at the discharge end of the vibrating plate. The discharge end of the vibrating material belt is connected to the feed end of the corresponding cutting device.

[0043] The cutting principle of the retaining ring cutting device and the washer cutting device is the same, only the internal dimensions or the stroke achieved differ. Similarly, the conveying principle of the washer conveying device is the same as that of the retaining ring conveying device. The following explanation uses only the washer cutting device and the washer conveying device as examples.

[0044] The washer cutting device includes a base, a cutting cylinder 32 disposed on one side of the base, a sliding block 31 disposed on the base, a sliding groove 34 formed in the sliding block 31, a receiving groove connected to the discharge end of the vibrating conveyor belt on one side of the sliding groove 34, a cutting block 33 disposed in the sliding groove 34, a receiving port formed at the front end of the cutting block 33, the receiving port matching the receiving groove, and the cutting cylinder 32 positioned at the rear end of the cutting block 33, driving the cutting block 33 to reciprocate within the sliding groove. Washers 37 enter the receiving groove from the vibrating conveyor belt of the feeding device, then from the receiving groove into the receiving port on the cutting block 33, thus entering the cutting block 33. The cutting cylinder 33 operates, moving the washer 37 in the receiving port forward to the washer removal port 35 of the sliding block 31, awaiting removal. After the washer is removed, the cutting cylinder drives the cutting block to reset, proceeding with the cutting of the next washer.

[0045] The washer handling device is located on one side of the washer cutting device and includes a linear guide rail 36 mounted on a support assembly and a base plate mounted on the linear guide rail 36. A lifting cylinder 38 is mounted on the base plate, and a clamping cylinder 39 for holding the product is connected to the lifting cylinder 38. During operation, the base plate moves above the washer on the linear guide rail 36, the lifting cylinder 38 operates, driving the clamping cylinder 39 downwards to clamp the washer. After clamping, the lifting cylinder 38 moves upwards and, through the linear guide rail 36, moves laterally to place the washer in the desired position.

[0046] In this embodiment, a guide pin transport device for transporting guide pins is also provided on one side of the angle adjuster feeding device. The guide pin transport device is used to transport the guide pins on the quick-change positioning fixture to the product before pressing. It mainly includes a first lifting cylinder 53 placed on the guide rail. A first transverse cylinder 54 is connected to one side of the first lifting cylinder 53. A first gripper cylinder 55 is connected to the first lifting cylinder 53.

[0047] After the angle adjuster is placed on the quick-change positioning fixture by the angle adjuster feeding device, the first transverse cylinder 54 operates, driving the first gripper cylinder 55 to move above the guide pin. This, in conjunction with the first lifting cylinder 53, grips the guide pin and places it into the guide pin positioning slot of the angle adjuster. The turntable then rotates to the next station for the placement of washers and retainers. Washers and retainers are sequentially placed on the guide pin by the corresponding device actions. The turntable then continues to rotate to the next station for the clamping of the washers and retainers onto the angle adjuster.

[0048] The pressing device includes a support frame disposed on one side of the turntable. A pressing cylinder 61 is disposed above the support frame. A pressing linear guide rail 63 is vertically connected to one side of the support frame. A lower pressing head 62 is connected to the pressing linear guide rail 63 via a slider. The upper end of the lower pressing head 62 is connected to the pressing cylinder 61 via a floating joint. The lower pressing head 62 has a pressing groove. When the pressing cylinder 61 is working, it drives the lower pressing head 61 to move downward on the pressing linear guide rail 63. The pressing groove covers the guide pin. The lower pressing head 62 presses the washer and retaining ring into the angle adjuster through the bottom of the lower pressing head 62, thus completing the pressing action.

[0049] The transfer device 7 is located on one side of the pressing device and is used to remove the guide pins from the product after pressing and place them on the guide pin support block 24 (i.e., restore the guide pins to their initial position). The structure of the transfer device 7 is similar to that of the guide pin handling device, including upper and lower cylinders and gripper cylinders. The difference is that, in order to avoid the guide pins affecting the angle adjuster during transfer, a pressure claw 71 is provided on one side of the upper and lower cylinders. When the guide pin is gripped and moved upward by the gripper cylinder, the pressure claw 71 will block the angle adjuster to prevent the angle adjuster from moving with the guide pin.

[0050] After the fasteners of the angle adjuster are tightened and assembled, this equipment can further inspect the tightness. The inspection device 8 includes an inspection drive cylinder 81 mounted on a support frame. The inspection drive cylinder 81 is connected to a displacement sensor 83 mounted on one side of the support frame via a connecting plate 82. When the inspection drive cylinder 81 operates, it drives the displacement sensor 83 to move along the guide rail on the support frame. A inspection component 84 is connected below the displacement sensor 83. The inspection component 84 includes a probe 842 and a probe rod 841 mounted inside the probe. The inspection principle of the inspection component 84 is as follows: when the inspection component 84 moves onto the product under the action of the inspection drive cylinder 81, the probe rod 841 abuts against the upper surface of the bearing of the angle adjuster, and the probe 842 abuts against the upper surface of the fastener 12. The displacement data of the inspection component is monitored by the displacement sensor 83, and the height of the fastener is used to determine whether the fastener is installed in place or whether there are any omissions.

[0051] The equipment also includes a guiding device 9 disposed on one side of the detection device. The guiding device includes a guiding gripper cylinder 91 mounted on a support frame, with a guiding positioning block 92 positioned above the guiding gripper cylinder 91. The angle adjuster is placed on the guiding positioning block 92 and is clamped by the guiding gripper cylinder 91 for guiding. The angle adjuster is gripped by a guiding transfer gripper cylinder 94 on one side of the turntable and flipped onto the guiding positioning block 92 by a guiding flipping cylinder 93 connected to one side of the guiding transfer gripper cylinder 94. After guiding is completed, the final product is transferred by a four-axis robot.

[0052] Of course, the press-fitting test of this utility model can also be applied to the press-fitting test of products that need to be assembled using the same principle.
