Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a machining side-push fixing clamp. Background Technology

[0002] Currently, when machining plate-shaped, block-shaped, or products with regular sides, the commonly used clamping device is a clamping plate driven horizontally by a cylinder, which directly pushes and clamps the product. This clamping method has a simple structure and direct action, and is widely used in production.

[0003] However, in practical applications, this traditional horizontal push fixture has gradually revealed some limitations. For example, since the cylinder and clamping plate are arranged horizontally, they occupy a large horizontal space on the worktable, resulting in an insufficiently compact fixture layout. In the working cavity of equipment such as machining centers, it may affect the movement of other components or limit the design of multi-station fixtures. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a machining side-push fixing fixture.

[0005] This utility model proposes a machining side-push fixing fixture, including a base plate. Positioning blocks are installed on both sides of the base plate, and several sets of side-push modules are installed on the other two sides of the base plate. The positioning blocks and side-push modules together clamp and fix the product. The side-push module includes a support plate and a cylinder installed on the top of the base plate. The top of the support plate is connected to a limit plate. A push plate and a side extrusion plate are movably arranged inside the limit plate. The telescopic end of the cylinder is connected to the push plate. The adjacent end faces of the push plate and the side extrusion plate are provided with mutually complementary first inclined surfaces and second inclined surfaces.

[0006] Furthermore, each of the positioning blocks has a stepped groove reserved at its top inner side to support and limit the product.

[0007] Furthermore, the limiting plate has a through hole inside, the push plate is inside the through hole and moves in the vertical direction, and the through hole is adapted to the push plate.

[0008] Furthermore, a limiting groove is formed at the top of the limiting plate, the limiting groove extends to the side of the limiting plate and communicates with the through hole.

[0009] Furthermore, the side extrusion plate is inside the limiting groove and moves in the horizontal direction, and the limiting groove is adapted to the side extrusion plate.

[0010] Furthermore, guide grooves are provided on both sides of the limiting groove, and guide protrusions are connected to both sides of the side extrusion plate. The guide protrusions are located inside the guide grooves and are compatible with each other.

[0011] The beneficial effects of this utility model are as follows: By setting a push plate and a side extrusion plate with mutually cooperating inclined surfaces, the vertical drive of the cylinder is converted into the horizontal clamping of the side extrusion plate, so that the cylinder can be installed vertically on the base plate, which greatly reduces the space occupied by the fixture in the horizontal direction. It effectively solves the problem that the traditional horizontal cylinder push fixture layout is not compact and is prone to interference with other components in the machining center, and provides the possibility for multi-station, high-density fixture layout.

[0014] Reference Figure 1-4 This utility model proposes a machining side-push fixing fixture, including a base plate 1. Positioning blocks 2 are installed on both sides of the base plate 1 for initial positioning of a product 4. Several sets of side-push modules 3 are installed on the other two sides of the base plate 1 for applying clamping force to the product 4 from the side. The positioning blocks 2 and the side-push modules 3 work together to achieve stable clamping of the product 4. The side push module 3 is specifically composed of a support plate 31, a cylinder 32, a limiting plate 33, a push plate 34, and a side extrusion plate 35. The support plate 31 and the cylinder 32 are both installed on the top of the base plate 1. The top of the support plate 31 is connected to the limiting plate 33. The push plate 34 and the side extrusion plate 35 are movably arranged inside the limiting plate 33. The telescopic end of the cylinder 32 is connected to the push plate 34 and is used to drive the push plate 34 to move in the vertical direction. The adjacent end faces of the push plate 34 and the side extrusion plate 35 are provided with mutually complementary first inclined surfaces 341 and second inclined surfaces 351. The transmission of force and the conversion of direction are realized through the cooperation of the inclined surfaces. A stepped groove 21 is reserved at the top of the inner side of the positioning block 2 to support and limit the product 4, and to prevent the product from shifting or tilting during the clamping process. The limiting plate 33 has a through hole 331 inside, and the push plate 34 is disposed inside the through hole 331 and can move vertically. The shape of the through hole 331 is adapted to the push plate 34 and serves as a guide. The top of the limiting plate 33 has a limiting groove 332, which extends to the side of the limiting plate 33 and communicates with the through hole 331. The side extrusion plate 35 is disposed inside the limiting groove 332 and can move horizontally. The shape of the limiting groove 332 is adapted to the side extrusion plate 35 to ensure the accurate movement trajectory of the side extrusion plate 35. To further improve the stability of the movement of the side extrusion plate 35, guide grooves 333 are provided on both sides of the limiting groove 332, and guide protrusions 352 are connected to both sides of the side extrusion plate 35. The guide protrusions 352 are located inside the guide grooves 333 and are adapted to the guide grooves 333 to play a guiding and anti-deviation role. When the piston rod of cylinder 32 retracts, it pulls the push plate 34 to move downwards in the vertical direction. The first inclined surface 341 of the push plate 34 interacts with the second inclined surface 351 of the side extrusion plate 35, converting the vertical thrust into a horizontal clamping force, pushing the side extrusion plate 35 to move horizontally toward the product 4, thus achieving lateral clamping of the product 4. When the piston rod of cylinder 32 extends, the push plate 34 returns to its original position, thereby separating the first inclined surface 341 and the second inclined surface 351. In other words, the push plate 34 no longer applies a thrust to the side extrusion plate 35. At this time, the side extrusion plate 35 is free to move, and the operator can lift the product 4 upwards and take it out. The same principle applies when placing the product 4.

[0015] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
