AI Technical Summary
Traditional clamping plates can easily cause indentations and scratches on the workpiece surface when clamping it, especially for workpieces with high surface finish requirements, resulting in economic losses.
Nylon pressure heads are embedded in the steel pressure plate, and combined with cushioning structures such as elastic pads and corrugated springs, the pressure is distributed to prevent the workpiece from being crushed.
It effectively prevents workpieces from being crushed during clamping, improves the workpiece qualification rate, and reduces production costs.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of fixture, concretely to a fixture pressing plate of preventing workpiece from being pressed. BACKGROUND
[0002] In the production process such as machining and assembly, fixture is an essential tool. The fixture pressing plate, as an important component of the fixture, is used to fix the workpiece on the fixture. The traditional fixture pressing plate is usually made of steel, which has high strength and rigidity. However, when clamping the workpiece, the high hardness of the steel can easily cause defects such as indentation and scratch on the surface of the workpiece, resulting in workpiece scrap and economic loss. Especially for workpieces with high surface finish requirements, this problem of pressing injury is more prominent.
[0003] Therefore, the present application provides a fixture pressing plate to solve the above technical problems. UTILITY MODEL CONTENT
[0004] The utility model discloses a fixture pressing plate of preventing workpiece from being pressed, which effectively prevents the workpiece from being pressed during clamping, improves the qualified rate of the workpiece, and reduces the production cost.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:
[0006] A fixture pressing plate of preventing workpiece from being pressed, comprising:
[0007] A steel pressing plate, which comprises a vertical section and two horizontal sections, is welded integrally in a Z shape, and a horizontal section at the upper end of the steel pressing plate is provided with an embedding groove on the bottom surface;
[0008] A nylon pressing head assembly, which is arranged in the embedding groove of the steel pressing plate through interference fit, comprises a buffer structure, a limiting boss and a pre-embedded metal insert, the metal insert is arranged in the embedding groove, the limiting boss is made of nylon material and is installed on the metal insert, and the buffer structure is arranged on the limiting boss and is used for buffering during clamping.
[0009] Further, the buffer structure adopts an elastic gasket, and the elastic gasket is provided with a rhombic grid pattern with a depth of 0.5-1mm.
[0010] Further, the buffer structure adopts a corrugated spring, and the corrugated spring is sleeved on the metal insert and abuts against the limiting boss and the steel pressing plate at both ends.
[0011] Further, the buffer structure is a cavity inside the limiting boss, and the cavity is filled with an elastic material.
[0012] Further, the metal insert is provided with a through-thread hole, and is connected with the steel pressing plate through a countersunk bolt.
[0013] Compared with the prior art, the utility model has the beneficial effects that:
[0014] By embedding the nylon pressing head on the steel pressing plate, the elasticity of the nylon material is utilized to disperse the pressure, effectively preventing the workpiece from being pressed during the clamping process; the structure of the nylon pressing head is simple, easy to manufacture and install, and low in cost; by adopting the buffering design of the elastic gasket, the corrugated spring and the internal cavity, the pressure on the workpiece is further reduced, and the anti-pressing effect is improved.
