[0025] Example 1
[0026] Since the existing method of manufacturing knobs involves manual installation one by one, which is inefficient and results in inconsistent installation quality, a fixture for installation was designed. The specific solution is as follows:
[0027] like Figure 1 As shown, a tooling fixture for improving the pressing accuracy of knobs includes: a base 1, a placement table 2, a support frame 3, and a pressing mechanism. The placement table 2 is slidably connected to the base 1 and is used to place the panel to be processed. The support frame 3 is fixedly installed on the base 1 and located behind the placement table 2. The pressing mechanism is fixedly installed on the upper front side of the support frame 3. The pressing mechanism is provided with a pressure plate that can be pressed down. The sliding stroke of the placement table 2 includes the lower part of the pressure plate. The pressure plate is connected to a pressure plate drive 4, and the pressure plate is raised or lowered by operating the pressure plate drive 4.
[0028] In this embodiment, the support frame 3 includes side plates 301 located on both sides. A fixing plate 302 is provided on the upper front side of the side plate 301 for installing the pressing mechanism. Two reinforcing plates 303 are arranged in parallel between the side plates 301. The reinforcing plates 303 can be used to reinforce the support frame 3 and also for the installation of the guide rod 504 mentioned below.
[0029] The support frame 3 is provided with guide rods 504. The rear part of the pressure plate is slidably connected to the guide rods 504. In this embodiment, two guide rods 504 are arranged parallel to each other on both sides of the reinforcing plate 303. The rear part of the mounting plate 502 is provided with guide rods 504 for slidable connection.
[0030] The placement platform 2 has a C-shaped structure with an opening facing forward. The top of the placement platform 2 is provided with a positioning groove 201 for placing the product with the knob to be installed. The interior of the placement platform 2 forms a cavity, which can be used to temporarily place other parts of the product. The product with the knob to be installed can have other structural parts connected in the front work station. The placement platform 2 is designed as a flat tabletop, which is inconvenient for placing products. Therefore, the placement platform 2 in this embodiment is designed to facilitate the placement of products.
[0031] In this embodiment, the placement platform 2 is composed of multiple plate components, specifically including a bottom plate at the bottom, support plates on both sides and the rear side, a C-shaped placement frame on the top of the support plate, the placement frame being connected to the support plate by screws, and a positioning groove 201 being formed on the placement frame.
[0032] In this embodiment, the pressure plate drive 4 is a quick clamping mechanism, which is convenient for users to operate quickly and is easy to replace. If there is any damage or failure, the entire quick clamping mechanism can be replaced directly. Moreover, if automation is to be improved, the quick clamping mechanism can be disassembled and replaced with a telescopic cylinder, which can improve automation without changing most of the tooling fixtures.
[0033] The pressure plate drive 4 is equipped with a connector at the connection point with the pressure plate, and the connector is screwed into the pressure plate drive 4. By turning the connector, the pressure plate can be finely adjusted up and down, which can adjust the final pressing pressure of the pressure plate and is suitable for use with different sized knobs.
[0034] The pressure plate consists of a connecting block 501, a mounting plate 502, and a contact plate 503 from top to bottom. The contact plate 503 is made of plastic to avoid damaging the knob. The connecting block 501 is used to connect the pressure plate to the pressure plate drive 4. The connecting block 501 is fixedly installed on the top of the mounting plate 502, and the contact plate 503 is fixedly installed on the bottom of the mounting plate 502.
[0035] A sliding component 202 is provided on each of the two sides of the bottom of the placement platform 2. The sliding component 202 is a combination of a slider and a slide rail. The slide rail is fixedly installed on the base 1, and the slider is fixedly installed on the bottom of the placement platform 2. The slider is slidably connected to the slide rail.
[0036] Instructions for use:
[0037] Initially, the placement platform 2 is at the front. After the worker places the product to be processed into the positioning slot 201, the entire placement platform 2 is pushed backward until the processing position is reached. A knob is pre-placed on the product to be processed. Then, the worker operates the quick clamping mechanism to press it down so that the contact part of the pressure plate contacts the knob. The knob is then installed on the product by continuously pressing down with the pressure plate. The quick clamping mechanism is then operated again to pry it upward so that the pressure plate moves away from the knob. Finally, the placement platform 2 is slid forward to remove the product, thus completing the processing.
[0038] The tooling fixture in this solution can complete the installation of multiple knobs at once, and can ensure that the installation quality of multiple knobs is consistent, which can ensure the product yield. Compared with the original manual installation of knobs one by one, the processing efficiency is higher and the fatigue of workers is reduced. The pressure plate can be adjusted to a certain extent, thereby controlling the pressing pressure or adapting the tooling fixture to knobs of different specifications. The placement table 2 can slide back and forth through the sliding component 202 to effectively separate the loading and unloading area from the operation area.
[0039] The entire tooling fixture has a simple structure. Compared with fully automated equipment, although it is not as efficient and still requires manual operation, it is low in cost and suitable for processing small batches of products, which can speed up the processing and delivery speed.
[0040] Example 2
[0041] In this embodiment, the structure of the tooling fixture is basically the same as that in Embodiment 1, the difference being that, for example... Figure 2 , 3 As shown, the pressure plate drive 4 is replaced by a telescopic cylinder. The telescopic end of the telescopic cylinder is screwed to the pressure plate. A second telescopic cylinder 6 is also provided at the rear of the base 1. The telescopic end of the second telescopic cylinder 6 is fixedly connected to the rear of the placement platform 2. The forward and backward displacement of the placement platform 2 can be controlled by the telescopic movement of the second telescopic cylinder 6. A control button 7 is also provided on one side of the base 1. The two telescopic cylinders are controlled by the control button 7. Compared with embodiment 1, the degree of automation is improved. The operator only needs to operate the control button 7 to place the product to be processed, which further reduces the labor intensity.
[0042] Example 3
[0043] In this embodiment, the tooling fixture is improved to a fully automated processing design. The base is equipped with a left-right conveyor belt mechanism for transporting products to the next workstation. The original processing position is equipped with a liftable pallet. When the product arrives, the pallet lifts and supports it. A pressure plate is located directly above the pallet. The support frame 3 adopts an L-shaped structure, allowing the pressure plate to extend forward and be positioned above the pallet. The pressure plate is raised and lowered by a telescopic cylinder to complete the installation of the knob. After the knob is installed, the pallet lowers, allowing the product to fall back onto the conveyor belt mechanism and be transported to the next workstation for processing. No manual intervention is required, resulting in higher processing efficiency.
[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
