Abstract
Description
Technical Field
[0001] This utility model relates to the field of bonding fixture technology, and in particular to a plastic processing part bonding fixture that is easy to replace. Background Technology
[0002] An adhesive jig is a tool used in industrial production to fix and position items to be bonded. It ensures the correct alignment and stability of the items during the bonding process. The design and function of adhesive jigs are crucial for improving production efficiency, ensuring product quality, and reducing costs.
[0003] Traditional bonding methods typically require manual alignment and fixation of plastic parts before bonding. This method is not only time-consuming and labor-intensive, but also prone to positional misalignment, resulting in unstable bonding quality. Therefore, we propose a plastic part bonding fixture that is easy to replace. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a plastic processing part bonding fixture that is easy to replace.
[0005] This utility model is achieved using the following technical solution: a plastic processing part bonding fixture that is easy to replace, including a fixed base, a positioning post threadedly connected to the inner wall of the fixed base, a vertical plate fixedly connected to the top of the fixed base, a mounting plate fixedly connected to the top of the vertical plate, a cylinder fixedly connected to the top of the mounting plate, the output end of the cylinder passing through the mounting plate and fixedly connected to a fixed plate, a pressure block fixedly connected to the bottom of the fixed plate, and a fixing component provided on the upper surface of the fixed base.
[0006] The above technical solution uses positioning pins to position the plastic parts. Since the positioning pins are threaded to the inner wall of the fixed base, they can be easily disassembled by rotating them. This allows for easy replacement of different positioning pins according to the size of the plastic parts, and the operation is simple, improving convenience and flexibility during use. The output end of the cylinder pushes the fixed plate and pressure block downwards, applying pressure to the plastic parts through the pressure block, making the two plastic parts fit tightly together until the adhesive is completely cured. This avoids manual pressing and fixing, making the force between the two plastic parts more stable and the adhesion stronger.
[0007] As a further improvement to the above solution, the fixing component includes a mounting frame, a motor is fixedly connected to the left end of the mounting frame, a bidirectional lead screw is fixedly connected to the output end of the motor, a mounting seat is threaded onto the surface of the bidirectional lead screw, a limit groove is formed in the inner wall of the mounting frame, an extension plate is fixedly connected to the front end of the mounting seat, and a clamping plate is fixedly connected to one end of the extension plate.
[0008] The above technical solution involves starting the motor, which drives the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw causes the two mounting seats to slide closer to each other along the limiting groove, thereby moving the two clamping plates closer to each other and clamping and fixing the two plastic parts to prevent displacement, thus improving the bonding quality. At the same time, it can adapt to plastic parts of different shapes and sizes, improving its applicability during use.
[0009] As a further improvement to the above solution, the bottom of the mounting bracket is fixedly connected to the top of the fixed base, and both ends of the bidirectional lead screw are rotatably connected to the wall of the mounting bracket.
[0010] As a further improvement to the above solution, the bottom of the mounting base is slidably connected to the inner wall of the limiting groove, and there are two mounting bases, which are symmetrically distributed around the mounting frame.
[0011] The above technical solution uses a limiting groove to limit the mounting base, allowing it to slide linearly along the limiting groove, thus improving stability during use.
[0012] As a further improvement to the above solution, the number of the extension plates and clamping plates corresponds to the number of the mounting base.
[0013] As a further improvement to the above solution, a limiting rod is fixedly connected to the top of the fixing plate, and the surface of the limiting rod is slidably connected to the inner wall of the mounting plate.
[0014] The above technical solution uses a limiting rod to limit the movement of the fixed plate, ensuring that the fixed plate moves in a straight line when it moves downwards, thus preventing deviation and making the pressure block more stable when pressing and bonding the plastic workpiece.
[0015] As a further improvement to the above solution, a control panel is fixedly connected to the upper surface of the fixed base.
[0016] The above technical solution allows for quick and easy control of the motor and cylinder via the control panel, improving ease of operation during use.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This utility model uses a fixing component, specifically a motor, to drive a bidirectional lead screw to rotate. The rotation of the bidirectional lead screw causes two mounting seats to slide closer to each other along the limiting groove, which in turn causes two clamping plates to move closer to each other, clamping and fixing two plastic parts to prevent displacement and thus improving the bonding quality. It can also adapt to plastic parts of different shapes and sizes.
[0019] This utility model features a fixed base and a positioning post. Specifically, the positioning post is threaded to the inner wall of the fixed base, allowing for easy disassembly by rotating the positioning post. This facilitates the replacement of different positioning posts according to the size of the plastic parts, and the operation is simple, improving the convenience and flexibility of use.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0028] Example:
[0029] Please combine Figure 1-5This embodiment provides a replaceable plastic part bonding fixture, including a fixed base 1. A positioning post 2 is threadedly connected to the inner wall of the fixed base 1. A vertical plate 3 is fixedly connected to the top of the fixed base 1. A mounting plate 4 is fixedly connected to the top of the vertical plate 3. A cylinder 5 is fixedly connected to the top of the mounting plate 4. The output end of the cylinder 5 passes through the mounting plate 4 and is fixedly connected to a fixing plate 6. A pressure block 7 is fixedly connected to the bottom of the fixing plate 6. A fixing component 8 is provided on the upper surface of the fixed base 1. When the cylinder 5 is activated, its output end pushes the fixing plate 6 and pressure block 7 downwards. Pressure is applied to the plastic parts through the pressure block 7, causing the two plastic parts to adhere tightly together until the adhesive is completely cured. Because the positioning post 2 is threadedly connected to the inner wall of the fixed base 1, it can be easily disassembled by rotating the positioning post 2. This facilitates the replacement of different positioning posts 2 according to the size of the plastic parts, and the operation is simple, improving convenience and flexibility during use.
[0030] The fixing component 8 includes a mounting bracket 801. A motor 802 is fixedly connected to the left end of the mounting bracket 801. A bidirectional lead screw 803 is fixedly connected to the output end of the motor 802. A mounting seat 804 is threaded onto the surface of the bidirectional lead screw 803. A limiting groove 805 is formed in the inner wall of the mounting bracket 801. An extension plate 806 is fixedly connected to the front end of the mounting seat 804. A clamping plate 807 is fixedly connected to one end of the extension plate 806. When the motor 802 is started, the motor 802 drives the bidirectional lead screw 803 to rotate. The rotation of the bidirectional lead screw 803 causes the two mounting seats 804 to slide closer to each other along the limiting groove 805, which in turn causes the two clamping plates 807 to move closer to each other, clamping and fixing the two plastic parts to prevent displacement and thus improving the bonding quality. It can also adapt to plastic parts of different shapes and sizes.
[0031] The bottom of the mounting bracket 801 is fixedly connected to the top of the fixed base 1, and the two ends of the bidirectional lead screw 803 are rotatably connected to the inner wall of the mounting bracket 801.
[0032] The bottom of the mounting base 804 is slidably connected to the inner wall of the limiting groove 805. There are two mounting bases 804, which are symmetrically distributed with the mounting bracket 801 as the center.
[0033] The number of extension plates 806 and clamping plates 807 corresponds to the number of mounting bases 804.
[0034] A limiting rod 9 is fixedly connected to the top of the fixing plate 6, and the surface of the limiting rod 9 is slidably connected to the inner wall of the mounting plate 4.
[0035] A control panel 10 is fixedly connected to the upper surface of the fixed base 1.
[0036] The implementation principle of the easily replaceable plastic part bonding fixture in this embodiment is as follows: During use, the plastic part to be bonded is placed on the positioning post 2. Since the size of the positioning post 2 matches the groove on the bottom of the plastic part to be bonded, it serves a positioning function. Then, adhesive is applied to the positioned plastic part. Another plastic part is placed on the part with adhesive applied. Then, the motor 802 is started, driving the bidirectional lead screw 803 to rotate. The rotation of the bidirectional lead screw 803 causes the two mounting seats 804 to slide closer to each other along the limiting groove 805, causing the two clamping plates 80... 7. The two plastic parts are moved closer to each other, clamping and fixing them to prevent displacement and thus improving the bonding quality. This method can also accommodate plastic parts of different shapes and sizes. Then, the cylinder 5 is activated. The output end of the cylinder 5 pushes the fixing plate 6 and the pressure block 7 downward. The pressure block 7 applies pressure to the plastic parts, making the two plastic parts fit tightly together until the adhesive is completely cured. Since the positioning post 2 is threaded to the inner wall of the fixing base 1, it can be easily disassembled by rotating the positioning post 2. This makes it easy to replace different positioning posts 2 according to the size of the plastic parts. Moreover, the operation is simple, improving the convenience and flexibility of use.
[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
