Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mold part clamps, in particular to a V-shaped flat-nose pliers. Background Art
[0002] In the current mold parts processing industry, clamping technology faces challenges, especially when processing complex geometric features such as grooves or grooves on circular parts. These parts not only require extremely high processing accuracy to ensure functionality and interchangeability after assembly, but also must remain stable during processing to prevent vibration and deformation, which is directly related to the quality of the finished product and production efficiency.
[0003] Traditional clamping processes, such as universal fixtures and direct use of machine tool vises, often fail to meet the processing requirements of such special parts. They may not be able to accurately center circular parts, or provide sufficient support and stability when processing deep and narrow grooves, resulting in reduced processing accuracy, impaired surface quality, and even damage to parts. In addition, universal fixtures are usually designed for workpieces of standard shapes and sizes, and have limited adaptability to non-standard or special-shaped parts, which increases the difficulty of clamping and may lead to improper selection of clamping points, thereby affecting processing efficiency and cost control. Although customized fixtures can be designed for specific parts to ensure the best clamping effect and processing accuracy, their high R&D costs, long production cycles, and high dependence on single parts make many small and medium-sized enterprises and processing workshops discouraged. Especially for small batches or diversified product orders, frequent replacement of fixtures is not only uneconomical, but also difficult to respond quickly to market changes. Utility Model Content
[0004] The utility model aims to provide a V-shaped flat-nose pliers to solve the problem that the existing general clamps cannot meet the clamping requirements of non-standard or special-shaped parts.
[0005] The technical solution of the utility model to solve the above technical problems is as follows:
[0006] A V-shaped flat-nose pliers comprises: a base, a fixed side forming block arranged at one end of the top of the base, and a movable side forming block slidably connected to a slideway of the base; a V-shaped groove for arranging special-shaped parts is vertically opened on the end face of the fixed side forming block close to the movable side forming block, and a semicircular boss is vertically arranged on the end face of the movable side forming block close to the fixed side forming block.
[0007] Furthermore, a moving side forming mounting block is provided at the end of the moving side forming block, and the moving side forming block and the moving side forming mounting block are fixed by bolts.
[0008] Furthermore, a fixing block is provided at the end of the movable side forming installation block, and the fixing block is fixed to the top end of the base by screws and pins respectively.
[0009] Furthermore, a mounting groove is provided at the end of the movable side forming mounting block, and a clamp handle is connected in the mounting groove.
[0010] Furthermore, a connecting hole is provided in the fixing block, and a screw rod of the clamp handle passes through the connecting hole.
[0011] Furthermore, the tail of the clamp handle is a cylinder.
[0012] Furthermore, the base is in an L-shaped structure.
[0013] The utility model has the following beneficial effects:
[0014] The V-groove design of this utility model can automatically center and stably clamp round or special-shaped parts of different diameters, ensuring the positioning accuracy of the parts during processing and reducing errors caused by manual adjustment. Through the sliding fit and bolt fixing design of the moving side forming block and the moving side forming mounting block, the user can quickly adjust the distance between the V-groove and the semicircular boss to meet the clamping requirements of parts of different sizes and improve work efficiency.
[0015] At the same time, the modular design between the moving side forming block and the mounting block makes it easy to replace damaged parts, reducing maintenance costs and equipment downtime. The clamp handle is designed as the tail of the cylinder, which is ergonomic and convenient for the operator to hold and apply force, especially when a large clamping force is required, which can effectively reduce the operator's fatigue. The L-shaped base structure provides a stable support platform and is suitable for installation on a variety of work surfaces. Whether it is a machine tool, a workbench or an assembly line operation, it can be flexibly adapted, which improves the versatility and flexibility of the tool. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0019] The present embodiment discloses a V-shaped flat-nose pliers, which aims to provide a device with a simple structure, convenient operation and the ability to effectively fix special-shaped parts, and is suitable for positioning and clamping parts in the fields of precision machining and assembly.
[0020] Please refer to Figure 1 The V-type flat-nose pliers mainly include the following components and their structural design:
[0021] 1. Base: The base 1 is designed as an L-shaped structure, which enhances the overall stability and load-bearing capacity. The bottom can be fixed on the workbench to ensure stability during operation. A slideway 11 is preset in the middle of the base 1 for sliding connection with the moving side forming block 3 for easy adjustment and positioning.
[0022] 2. Fixed side forming block: The fixed side forming block 2 is installed at one end of the top of the base 1, and a V-shaped groove 21 is vertically opened on the end surface close to the movable side forming block 3. The design of the V-shaped groove 21 is suitable for accommodating various special-shaped parts with different cross-sectional shapes, and the automatic alignment of the parts is realized through adaptive adjustment to ensure the processing accuracy.
[0023] 3. Mobile side forming block and mounting block: The mobile side forming block 3 is slidably connected to the slideway 11 of the base 1, and a semicircular boss 31 is set on its end face close to the fixed side forming block 2, which is used in conjunction with the V-shaped groove 21 to form a closed clamping structure to effectively fix the parts. The end of the mobile side forming block 3 is connected to the mobile side forming mounting block 4, and the two are fixed by high-strength bolts to ensure stability and position accuracy during movement. The end of the mobile side forming mounting block 4 is provided with a mounting groove 41, and the mounting groove 41 is connected to the clamp handle 6.
[0024] 4. Fixed block and clamp handle: The end of the moving side forming installation block 4 is fixed with a fixed block 5, which is fixed to the top of the base 1 by screws and pins, further improving the stability of the entire device. A connecting hole 51 is provided inside the fixed block 5 for passing the screw of the clamp handle 6 to install the handle. The clamp handle 6 is designed with a cylindrical tail to facilitate the operator to apply force and achieve precise control of the moving side forming block 3.
[0025] 5. Operation method: The user rotates the clamp handle 6 to drive the movable side forming block 3 to move along the slide 11 until the V-shaped groove 21 and the semicircular boss 31 are completely in contact with the two sides of the part to be processed, thus achieving the effect of automatic alignment. Then, continue to tighten the clamp handle, and the force transmitted by the screw will firmly clamp the part, ready for subsequent processing or testing operations.
[0026] The V-shaped flat-nose pliers of this embodiment, through a simple and ingenious structural design, realize the rapid and accurate alignment and clamping of special-shaped parts, improve work efficiency, and reduce processing errors caused by inaccurate positioning. In addition, the design of the L-shaped base enhances the overall rigidity of the device, and the adjustable movable side forming block gives the device a wide range of applicability, meeting the processing requirements of parts of different sizes and shapes.
