Description

Technical Field

[0001] This utility model relates to the field of shielding fixture technology, specifically a shielding clamping fixture. Background Technology

[0002] A masking fixture is a specialized tool used in surface treatment processes (such as spraying, electroplating, and coating) to mask and protect areas that do not require treatment. Through precise masking design, it ensures that only the target area is treated, thereby improving machining accuracy, reducing costs, and increasing production efficiency. The origins of fixtures can be traced back to the early Industrial Revolution, when increasingly demanding machining requirements necessitated specialized tools to fix and position workpieces to ensure machining accuracy and efficiency. With the continuous development of machining technology, fixtures have also evolved and improved, becoming an indispensable tool in modern manufacturing.

[0003] The existing technology still has the following drawbacks in its use:

[0004] In the existing masking clamping fixture, the product is placed in the clamping slot. Once the product is in the clamping slot, it is fixed in the clamping slot through the threaded hole at the rear end. However, when the threaded hole at the rear end is threaded, the product on the fixture plate is prone to detach from the contact surface at the bottom, resulting in inaccurate thread fixing.

[0005] In view of this, we propose a shielding clamping fixture to solve the existing problems. Utility Model Content

[0006] The purpose of this invention is to provide a shielding clamping fixture to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a shielding clamping fixture, comprising a fixture plate, a positive plate provided at the upper end of the fixture plate, multiple clamping grooves provided at the upper end of the fixture plate, multiple sets of moving grooves provided on both sides of the clamping grooves, a clamping plate provided on the moving grooves, a knob block provided on one side of the fixture plate, a threaded rod connected to the knob block, a fixing nut connected to the threaded rod through the fixture plate, multiple sets of moving blocks connected to the threaded rod, connecting plates connected to both sides of the moving blocks, and the connecting plates fixed to the lower end of the clamping plate.

[0008] Preferably, the back of the fixture plate is provided with a back plate, and the back plate is provided with a plurality of screw holes evenly distributed thereon, the screw holes penetrating the fixture plate and connecting to the sliding groove.

[0009] Preferably, protective protrusions that fit the product are provided on both sides of the clamping groove.

[0010] Preferably, the fixture plate has a limiting groove inside, and the moving block is installed inside the fixture plate through the limiting groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model incorporates a knob block within the shielding clamping fixture. This knob block moves the clamping plates on both sides of the clamping groove to a certain extent. After the product is positioned within the clamping groove, clamping the product makes threaded fixing of the rear end more convenient. The product is less likely to detach from the bottom contact surface, ensuring the ease of threaded fixing. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention proposes a shielding clamping fixture, including a fixture plate 1, a positive plate 3 at the upper end of the fixture plate 1, multiple clamping grooves 2 at the upper end of the fixture plate 1, multiple sets of moving grooves 5 on both sides of the clamping grooves 2, clamping plates 4 on the moving grooves 5, a knob block 6 on one side of the fixture plate 1, a threaded rod 9 connected to the knob block 6, the threaded rod 9 passing through the fixture plate 1 and connected to a fixing nut 12, multiple sets of moving blocks 11 connected to the threaded rod 9, connecting plates 10 connected to both sides of the moving blocks 11, and the connecting plates 10 fixed to the lower end of the clamping plate 4.

[0021] After the product is placed in the clamping slot 2, it fits snugly in the clamping slot 2. By rotating the knob block 6, the threaded rod 9 can start to rotate, thereby driving the moving block 11 and the clamping plate 4 to move towards the center position to initially fix the product in the clamping slot 2. By tightening the fixing nut 12, a stable fixation is achieved. Then, the product can be more easily fixed through the threaded hole on the back of the fixture plate 1. After fixing through the threaded hole, the clamping plate 4 can be removed from the product.

[0022] Furthermore, a back plate 7 is provided on the back of the fixture plate 1, and multiple sets of screw holes 8 are evenly arranged on the back plate 7. The screw holes 8 penetrate the fixture plate 1 and are connected to the sliding groove.

[0023] The product can be fixed in the clamping slot 2 of the fixture plate 1 through the screw hole 8.

[0024] Furthermore, protective protrusions that fit the product are provided on both sides of the clamping groove 2.

[0025] Protective bumps are used to conform to the shape of the product, which can initially prevent the product from falling off.

[0026] Furthermore, a limiting groove is provided inside the fixture plate 1, and the moving block 11 is installed inside the fixture plate 1 through the limiting groove.

[0027] The limit slot is used to support the movement of the moving block 11, thereby ensuring the smooth movement of the moving block 11.

[0028] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
