[0030] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0031] Example 1
[0032] like Figure 1As shown, an automatic rear shock absorber sleeve pressing device includes a damper positioning fixture 2 installed on a working platform 1 and a bushing pressing fixture 3 located in front of the damper positioning fixture 2.
[0033] The damper positioning fixture 2 includes a first support 21, a guide component 22 mounted on the first support 21, a tray 23 that moves under the drive of the guide component 22, and a base support 24 mounted on the tray 23 and matched with the shape of the damper 100.
[0034] The bushing pressing fixture 3 includes a second support base 31, a column press 32 mounted on the second support base 31, and a positioning base 33 mounted on the second support base 31. The damper pressing part 101 is matched and placed on the positioning base 33, and a positioning post 34 is provided in the middle of the positioning base 33. After the bushing is matched and placed on the positioning post 34, the column press 32 presses the bushing 200 onto the damper pressing part 101.
[0035] In this embodiment, by using a precise damper positioning fixture 2 in conjunction with a bushing pressing fixture 3, the workpiece can be kept stable during processing, reducing human error and improving processing accuracy. Although the initial investment may be high, in the long run, the semi-automatic processing fixture can reduce the manufacturing cost per unit product because it improves production efficiency and reduces scrap rate.
[0036] Furthermore, such as Figure 6 As shown, the guide assembly 22 includes a guide rail 221 mounted on the first support base 21, a guide seat 222 connected to the bottom of the tray 23 and slidably disposed on the guide rail 221, a positioning rail 223 disposed side by side on one side of the guide rail 221 and having a serrated upper end, and elastic balls 224 disposed below the tray 23 and intermittently matched and engaged with the positioning rail 223.
[0037] It should be noted that by setting the guide component 22, the position of the damper can be easily adjusted, and the upper mounting position and pressing position can be smoothly switched to avoid mutual interference between the workstations. At the same time, the elastic ball bearing 224 and the positioning rail 223 are used to ensure that the damper can be automatically limited when it moves to any position. This structure is flexible in terms of the operator's requirements for the upper mounting position, convenient to use and precise in processing. It has a certain degree of flexibility and can be adjusted and reconfigured according to different processing needs. It is suitable for a variety of different types of workpieces and processing tasks.
[0038] Furthermore, such as Figure 1 As shown, a detector 4 is provided on the rear side of the bushing pressing fixture 3, and the detector 4 is installed on the working platform 1.
[0039] Among them, detector 4 is used to detect whether the bushing and damper are in place. Once in place, the sensor transmits a signal and the column press 32 starts working.
[0040] Furthermore, such as Figure 5 As shown, the damper positioning fixture 2 and the bushing pressing fixture 3 are installed in a cross direction to maximize the use of the work platform, with a reasonable layout and convenient operation.
[0041] Furthermore, such as Figure 3 As shown, a bushing rack 5 is provided on the rear side of the damper positioning fixture 2. The bushing rack 5 has two layers, and each layer has several sets of material frames 50 placed from front to back, with several bushings placed inside the bushing rack 5.
[0042] Furthermore, such as Figure 3-4 As shown, a damper temporary storage fixture 6 is provided in front of the bushing rack 5. The damper temporary storage fixture 6 includes a base 61 mounted on the working platform 1, a mounting frame 62 mounted on the base 61, a bracket 63 located on one side of the mounting frame 62 and vertically mounted on the base 61, and a bayonet 64 provided on the bracket 63 and adapted to the shape of the damper. The bayonet 64 is a semi-open structure.
[0043] Furthermore, one end of the damper is inserted into the mounting frame 62, and the rod portion of the damper 100 leans against the bayonet 64 at an angle.
[0044] It should be noted that the damper temporary storage fixture 6 can be used to quickly place qualified products for temporary storage. During the pressing operation, the qualified products can be transferred to the next station, which is in line with the work rhythm.
[0045] Furthermore, such as Figure 1 As shown, it also includes a cable tray 8 installed on the work platform 1, and a triangular light 9 is provided on one side of the cable tray.
[0046] Example 2
[0047] Components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:
[0048] Furthermore, such as Figure 3-4 As shown, an NG storage fixture 7 is provided between the damper temporary storage fixture 6 and the damper positioning fixture 2. The NG storage fixture 7 includes a feed cylinder 71 and a storage box 72 located below the feed cylinder 71. A sliding door 73 is provided on the front side of the storage box 72.
[0049] Furthermore, the NG storage fixture 7 is installed on the work platform 1 and located below the damper temporary storage fixture 6.
[0050] In this system, defective products that are not properly pressed are placed in the NG storage fixture 7. Later, the defective products in the storage box 72 are transferred by opening the pull door 73. At the same time, the vertically set feeding cylinder 71 facilitates the guiding feeding of defective products and also facilitates human operation. When the operator removes the product from the damper positioning fixture 2, he will instinctively hold the damper vertically, which facilitates quick operation, reduces the frequency and intensity of manual operation by workers, reduces labor intensity, improves the working environment, and helps to attract and retain skilled workers.
[0051] Work steps:
[0052] The damper is manually removed from the damper trolley and loaded onto the damper positioning fixture 2. Then, the bushing is manually removed from the bushing rack and loaded onto the bushing pressing fixture 3. After scanning the code manually, the start button is pressed. The damper positioning fixture 2 moves to the column press 32. The sensor detects whether the bushing and damper are present. The column press 32 presses the product. If the product is not present, manual intervention is required. The product is unloaded into the product storage fixture 7. If the product is qualified, it is unloaded into the damper temporary storage fixture 6.
[0053] In the description of this utility model, it should be understood that the terms "front and back", "left and right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation.
