Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, specifically to a quick clamping clamp for a grinding platform, which improves the clamping efficiency and operational safety of small workpieces. Background Technology

[0002] In the grinding process of metal workpieces, traditional bench vises typically use adjustable fixed jaws and lead screws to drive the moving jaws to clamp the workpiece. Although the clamping force is stable, clamping requires multiple rotations of the handle, which is time-consuming, especially for small parts that need to be frequently changed, resulting in low efficiency. In addition, the operator holding the high-speed rotating tool during grinding operations is prone to accidental contact, posing a safety hazard. Therefore, there is an urgent need for a specialized fixture that combines rapid clamping, safety protection, and dimensional adaptability. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the present invention aims to provide a quick clamping clamp for a grinding platform to solve the defects of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A quick clamping clamp for a grinding platform. Includes: a clamp body (1), with two parallel slide rails (11) on its top; an adjustable fixed jaw (2) with a groove at the bottom that mates with the slide rails (11), and locking screws (21) on both sides, and rigidly connected to the nut (41) of the lead screw nut pair (4); a quick-moving jaw (3) with a groove at the bottom that mates with the slide rails (11), and connected to the push rod (51) of the quick clamping device (5); the two ends of the lead screw (42) of the lead screw nut pair (4) are fixed to one side of the clamp body (1) by bearing seats (12), and the outward end is provided with a rotating handle (43); the base (52) of the quick clamping device (5) is fixed to the other side of the clamp body (1), and the push rod (51) is driven to move linearly along the slide rails (11) by moving the quick clamping handle (53); the working surfaces of the adjustable fixed jaw (2) and the quick-moving jaw (3) are provided with magnetically replaceable soft clamping pads (54).

[0006] Preferably, the slide rail (11) is an L-shaped linear guide rail.

[0007] Preferably, the lead screw (42) is a trapezoidal threaded lead screw, and its axis is parallel to the extension direction of the slide rail (11).

[0008] Preferably, the quick clamping device (5) is a crank-guide rod type quick locking device, and the quick clamping handle (53) is a clamping handle that can swing back and forth. Attached Figure Description

[0010] Figure 2 This is a schematic diagram of the component connections of this utility model;

[0011] Figure 3 This is a schematic diagram illustrating the operating principle of the quick-clamping device. Detailed Implementation

[0012] like Figure 1-3 As shown, the clamp body (1) is made of cast iron as a whole, and two L-shaped slide rails (11) are machined on the top. The adjustable fixed jaw (2) cooperates with the slide rail (11) through the bottom slide groove, and the locking screws (21) on both sides can lock it relative to the slide rail (11); the back of the adjustable fixed jaw (2) is fixed to the nut (41) of the lead screw nut pair (4) by the set screw. The lead screw (42) has a trapezoidal thread, and both ends are supported by the bearing seats (12) of the clamp body (1). Rotating the handle (43) can drive the adjustable fixed jaw (2) to move along the slide rail (11) to achieve coarse adjustment of the clamping range. Tightening the locking screws (21) on both sides of the adjustable fixed jaw (2) increases the stability of the adjustable fixed jaw (2).

[0013] The quick-clamping device (5) adopts a crank-guide rod structure. The base (52) is fixed to the right side of the clamp body (1) with screws, and the front end of the push rod (51) is fixed to the quick-moving jaw (3) with bolts. When the handle (53) is turned, the crank drives the connecting rod to press the push rod (51) to produce a linear displacement, which drives the quick-moving jaw (3) to quickly approach or move away from the workpiece and self-locks at the dead point position. The working surface of the jaw is equipped with a replaceable soft clamping pad (54) with magnetic attraction to prevent the workpiece from slipping and to facilitate easy replacement.

[0014] During operation, first rotate the screw handle (43) to adjust the adjustable fixed jaw (2) to the appropriate position, then tighten the locking screws (21) on both sides. After placing the workpiece, move the quick clamp handle (53) forward with one hand to complete the clamping. When releasing, push the handle (53) backward to quickly move the jaw (3) and automatically reset. No tools are needed throughout the process.

[0015] Beneficial effects: The step-by-step operation of adjusting the jaw clamping size and quick-clamp locking via the lead screw balances the needs of adapting to a wide range of sizes and instantaneous clamping.

[0016] The single-handle operation mode of the quick-clamp device significantly shortens the clamping time, making it particularly suitable for assembly line grinding operations.

[0017] The self-locking jaws prevent loosening caused by grinding vibrations, and the magnetically replaceable soft clamping pads can be quickly replaced when necessary, reducing the risk of workpiece surface damage.
