Detailed Implementation

[0027] The present invention will now be described in conjunction with specific embodiments.

[0028] Example 1, as Figure 3 and Figure 4 As shown, a wiper arm extension arm and wiper bar riveting assembly equipment includes a frame (not shown in the figure), the frame is equipped with a base 1; the base 1 is equipped with a wiper bar positioning fixture 2 for positioning and placing the wiper bar 102, and an extension arm positioning fixture 3 located on the right end of the wiper bar positioning fixture 2 for positioning and placing the extension arm 103.

[0029] Among them, such as Figure 3 As shown, the wiper arm extension arm and wiper bar riveting assembly equipment also includes a riveting assembly 4 and a wiper bar pressing and positioning assembly 5.

[0030] Furthermore, such as Figures 3 to 5 As shown, the riveting assembly 4 includes a front riveting block 41 located in front of the scraper positioning fixture 2, a rear riveting block 42 located behind the scraper positioning fixture 2, and a cylinder mounting seat 43 located below the base 1. The front riveting block 41 and the rear riveting block 42 are arranged opposite each other at intervals, and the front riveting block 41 and the rear riveting block 42 are pivotally connected to the base 1 via pivots 44 respectively. The upper end of the cylinder mounting seat 43 is connected to the base 1, and a vertically moving riveting drive cylinder 45 is screwed onto the cylinder mounting seat 43. The riveting drive cylinder 45 drives the front riveting block 41 and the rear riveting block 42 to perform opening and closing actions.

[0031] In the process of riveting and assembling the extension arm 103 and the wiper bar 102 using the wiper arm extension arm and wiper bar riveting and assembly equipment of this embodiment, the steps include: Step a: Place the extension arm 103 on the extension arm positioning fixture 3, and the extension arm positioning fixture 3 positions the extension arm 103. Step b: Place the scraper 102 on the scraper positioning fixture 2. The scraper positioning fixture 2 has a contour positioning groove. The scraper positioning fixture 2 positions the scraper 102 through its scraper positioning groove. At this time, the rear end of the scraper 102 coincides with the front end of the extension arm 103. Step c: After the scraper rod 102 is placed and positioned by the scraper rod positioning fixture 2, the scraper rod pressing and positioning component 5 is activated, and the scraper rod pressing and positioning component 5 presses and assists in positioning the scraper rod 102 to ensure that the relative position of the pressing rod and the extension arm 103 is fixed when the riveting component 4 is activated. Step d: After the scraper rod holding and positioning assembly 5 assists in holding and positioning the pressure rod, the riveting assembly 4 is activated. During this process, the riveting drive cylinder 45 drives the front riveting block 41 and the rear riveting block 42 to move synchronously, so that the front riveting block 41 and the rear riveting block 42 close. The upper ends of the front riveting block 41 and the upper ends of the rear riveting block 42 press against the edge of the extension arm 103 and cause the edge of the extension arm 103 to bend and deform. Under the pressing action of the front riveting block 41 and the rear riveting block 42, the edge of the front end of the extension arm 103 folds over and hugs the rear end of the scraper rod 102, so that the rear end of the scraper rod 102 is pressed and riveted to the front end of the extension arm 103. Step e: After the scraper rod 102 and the extension arm 103 are riveted together, the riveting drive cylinder 45 drives the front riveting block 41 and the rear riveting block 42 to open, the scraper rod holding and positioning assembly 5 is reset and retracted from the pressure rod, and finally the riveted pressure rod and extension arm 103 are removed from the pressure rod positioning fixture and the extension arm positioning fixture 3.

[0032] In summary, through the above structural design, the wiper arm extension arm and wiper bar riveting assembly equipment of this embodiment can automatically complete the riveting assembly of the pressure bar and extension arm 103. That is, the wiper arm extension arm and wiper bar riveting assembly equipment of this embodiment has the advantages of novel structural design and high degree of automation, and can be effectively applied to the riveting assembly processing of wiper arm extension arm 103 and wiper bar 102.

[0033] Example 2, as Figure 3 , Figure 8 as well as Figure 9 As shown, the difference between this embodiment 2 and embodiment 1 is that the scraper holding and positioning assembly 5 includes a front-to-back translational movable seat 51 that is slidably mounted on the base 1 via a guide rail slider pair. The base 1 is equipped with a translational drive cylinder 52 that moves horizontally back and forth, and the drive end of the translational drive cylinder 52 is connected to the front-to-back translational movable seat 51.

[0034] The upper end of the front-to-back translational movable seat 51 is equipped with a linear drive module 53 for left-to-right horizontal movement. The drive end of the linear drive module 53 is equipped with a left-to-right translational movable seat 54. The left-to-right translational movable seat 54 is equipped with a lifting drive cylinder 55 for lifting and lowering movement. The drive end of the lifting drive cylinder 55 is equipped with a lifting movable seat 56 that is slidably mounted on the left-to-right translational movable seat 54 via a guide rail slider pair.

[0035] In addition, the lifting movable seat 56 is equipped with a pressure rod drive cylinder 571 for lifting action. The drive end of the pressure rod drive cylinder 571 is connected to a scraper pressure rod 572. The lifting movable seat 56 is equipped with a scraper positioning rod 581 on the side of the scraper pressure rod 572.

[0036] During the process of the scraper rod holding and positioning assembly 5 assisting in holding and positioning the scraper rod 102 on the scraper rod positioning fixture 2, the translation drive cylinder 52 drives the forward and backward translational movable seat 51 to move forward, thereby causing the scraper rod pressure rod 572 and the scraper rod positioning rod 581 to move forward to be directly above the scraper rod 102 on the scraper rod positioning fixture 2. Then, the linear drive module 53 drives the left and right horizontal movable seats to move left and right to adaptively adjust the scraper rod pressure rod 572 and the scraper rod positioning rod according to the size specifications of the pressure rod. The left and right positions of 581 are then adjusted. The lifting drive cylinder 55 drives the lifting movable seat 56 to move downwards, so that the scraper positioning rod 581 is inserted into the spring mounting hole 1021 of the scraper 102. That is, the scraper positioning rod 581 cooperates with the spring mounting hole 1021 to further assist in the positioning of the scraper 102. Finally, the pressure rod drive cylinder 571 drives the scraper pressure rod 572 to move downwards, so that the scraper pressure rod 572 presses and holds the scraper 102 on the fixed scraper positioning fixture 2.

[0037] After the scraper rod 102 and the extension arm 103 are riveted and assembled, the translation drive cylinder 52, the linear module drive, the lifting drive cylinder 55, and the pressure rod drive cylinder 571 reset, so that the scraper rod pressure rod 572 and the scraper rod positioning rod 581 retract from the scraper rod 102.

[0038] Example 3, as Figure 8 and Figure 9 As shown, the difference between this embodiment 3 and embodiment 2 is that: the lifting movable seat 56 is screwed with a positioning rod mounting seat 582 corresponding to the scraper positioning rod 581. The positioning rod mounting seat 582 has a vertically penetrating positioning rod mounting hole 5821. The scraper positioning rod 581 is movably embedded in the positioning rod mounting hole 5821, and the lower end of the scraper positioning rod 581 extends to the lower end side of the positioning rod mounting seat 582.

[0039] The scraper positioning rod 581 is provided with a positioning rod shoulder 5811, and the inner wall of the positioning rod mounting hole 5821 is provided with a mounting seat shoulder 5822 located on the lower end side of the positioning rod shoulder 5811.

[0040] In addition, the scraper positioning rod 581 is fitted with a compression spring 583. The upper end of the compression spring 583 elastically abuts against the positioning rod mounting base 582, and the lower end of the compression spring 583 elastically abuts against the positioning rod shoulder 5811 of the scraper positioning rod 581.

[0041] Regarding the mounting seat shoulder 5822 in this embodiment, it is located below the positioning rod shoulder 5811. When the pressure rod positioning rod moves down to the lower limit position relative to the positioning rod mounting seat 582, the positioning rod shoulder 5811 of the scraper positioning rod 581 abuts against the mounting seat shoulder 5822. Through the cooperation between the mounting seat shoulder 5822 and the positioning rod shoulder 5811, this embodiment can effectively prevent the scraper positioning rod 581 from exiting downward from the positioning rod mounting hole 5821.

[0042] Example 4, as Figure 5 As shown, the difference between this embodiment four and embodiment one is that: the piston rod extension end of the riveting drive cylinder 45 is equipped with a riveting drive plate 46 arranged horizontally, and the riveting drive plate 46 is slidably mounted on the cylinder mounting base 43 through the guide rail slider pair, and the lower ends of the front riveting block 41 and the rear riveting block 42 are in contact with the riveting drive plate 46 respectively.

[0043] The front end of the riveting drive plate 46 is equipped with a front reset lever 471 corresponding to the front riveting block 41, and the rear end of the riveting drive plate 46 is equipped with a rear reset lever 472 corresponding to the rear riveting block 42.

[0044] When the riveting drive cylinder 45 drives the front riveting block 41 and the rear riveting block 42 to close and realize the riveting assembly of the scraper 102 and the extension arm 103, the riveting drive cylinder 45 drives the riveting drive plate 46 to move upward. The upward-moving riveting drive plate 46 pushes the lower end of the front riveting block 41 and the lower end of the rear riveting block 42. Under the pushing action of the riveting drive plate 46, the upper end of the front riveting block 41 flips backward and the upper end of the rear riveting block 42 flips forward, so as to realize the closure of the upper end of the front riveting block 41 and the upper end of the rear riveting block 42.

[0045] During the process of the riveting drive cylinder 45 driving the front riveting block 41 and the rear riveting block 42 to open, the riveting drive cylinder 45 drives the riveting drive plate 46 to move downward. The downward moving riveting drive plate 46 drives the front reset pull rod 471 and the rear reset pull rod 472 to move downward simultaneously. The downward moving front reset pull rod 471 will pull the lower end of the front riveting block 41 downward, and the downward moving rear reset pull rod 472 will pull the lower end of the rear riveting block 42 downward, thereby causing the upper end of the front riveting block 41 to flip forward and the upper end of the rear riveting block 42 to flip backward, so as to open the front riveting block 41 and the rear riveting block 42.

[0046] Example 5, as Figure 5 As shown, the difference between this embodiment 5 and embodiment 4 is that: the base 1 is equipped with a front elastic member 481 corresponding to the front riveting block 41, and the front elastic member 481 elastically presses the front riveting block 41 downward.

[0047] Similarly, the base 1 is equipped with a rear elastic element 482 corresponding to the rear riveting block 42, and the rear elastic element 482 elastically presses the rear riveting block 42 downward.

[0048] Example 6, as Figure 5 As shown, the difference between this embodiment six and embodiment four is that: a front roller is rotatably mounted on the lower end of the front riveting block 41, and a rear roller is rotatably mounted on the lower end of the rear riveting block 42. The front roller and the rear roller respectively roll in contact with the upper surface of the riveting drive plate 46.

[0049] The front riveting block 41 contacts the upper surface of the riveting drive plate 46 via the front roller, and the rear riveting block 42 contacts the upper surface of the riveting drive plate 46 via the rear roller. By setting the front roller and the rear roller, this embodiment six can effectively reduce the wear of the front riveting block 41 and the rear riveting block 42.

[0050] Example 7, as Figure 6 and Figure 7 As shown, the difference between this embodiment seven and embodiment one is that the extension arm positioning fixture 3 includes an extension arm positioning seat 31, and the extension arm positioning seat 31 has an extension arm positioning groove 311 for the rear end of the extension arm 103 to be inserted.

[0051] The extension arm positioning seat 31 has a positioning seat through hole 312 that runs through the front and rear and communicates with the extension arm positioning groove 311. A front positioning cylinder 321 is installed on the front side of the positioning seat through hole 312, and a rear positioning cylinder 322 is installed on the rear side of the positioning seat through hole 312. The front positioning cylinder 321 and the rear positioning cylinder 322 are screwed into the extension arm positioning seat 31. A front positioning rod 331 is installed at the driving end of the front positioning cylinder 321, and a rear positioning rod 332 is installed at the driving end of the rear positioning cylinder 322. The front positioning rod 331 and the rear positioning rod 332 are slidably installed in the positioning seat through hole 312.

[0052] In the process of positioning the extension arm 103 by the extension arm positioning fixture 3 in this embodiment 7, the rear end of the extension arm 103 is first placed into the extension arm positioning groove 311 of the extension arm positioning seat 31. Then, the front positioning cylinder 321 and the rear positioning cylinder 322 are activated. The front positioning cylinder 321 drives the front positioning rod 331 to move backward, and the rear positioning cylinder 322 drives the rear positioning rod 332 to move forward, so that the front positioning rod 331 and the rear positioning rod 332 are respectively inserted into the rivet 105 hole of the extension arm 103 to achieve the positioning of the extension arm 103.

[0053] It should be noted that the rear end of the front positioning rod 331 and the front end of the rear positioning rod 332 are respectively conical in shape. This shape design of the front positioning rod 331 and the rear positioning rod 332 facilitates the alignment of the rivet 105 hole.
