Description

Technical Field

[0001] This utility model belongs to the field of clamping technology, and in particular relates to a centering clamping clamp. Background Technology

[0002] Small clamps used on general machines are basically fixed at one end and movable at the other. When an item is placed between the fixed end and the movable end, the movable end will move towards the fixed end to clamp the item.

[0003] Existing centering clamps are prone to falling off during operation and transfer. In view of this, we propose a new centering clamp. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a centering clamping fixture that avoids the problem of easy detachment during operation and transfer.

[0005] In view of this, the present invention provides a centering clamping fixture, including a mounting base, a base plate fixedly connected to the outer wall of the mounting base, a pneumatic push rod fixedly connected to the side wall of the base plate, an active slide fixedly connected to the output end of the pneumatic push rod, a limit slide rail fixedly connected to the bottom end of the active slide and the outer wall of the base plate, an active clamping block fixedly connected to the top end of the active slide, an active rod hinged to the side wall of the active slide, a rotating plate hinged to one end of the active rod and spun to the outer wall of the base plate, a driven rod hinged to one end of the rotating plate, a driven slide slidably connected to the top end of the limit slide rail, a driven clamping block fixedly connected to the top end of the driven slide, a lifting cylinder fixedly connected to the outer wall of the base plate, a lifting seat fixedly connected to the output end of the lifting cylinder, and a push plate fixedly connected to the top end of the lifting seat.

[0006] Based on the above structure, the pneumatic push rod drives the active slide to slide along the outer wall of the limiting slide rail. The sliding of the active slide causes the active clamping block to slide synchronously. At the same time, the sliding of the active slide drives the rotating plate to rotate through the active rod. The rotation of the rotating plate drives the driven slide to slide along the outer wall of the limiting slide rail through the driven rod. The sliding of the driven slide causes the driven clamping block to slide synchronously relative to the active clamping block, thereby performing a stable clamping operation on the workpiece.

[0007] Preferably, the mounting base has a "T" shaped cross-section, and the base plate is provided in two sets, with the two sets of base plates being centrally symmetrical about the center of the mounting base. In this embodiment, by providing a mounting base with a "T" shaped cross-section, the stability of the base plate is improved.

[0008] Preferably, the active slide block forms a sliding structure with the limiting slide rail via a pneumatic push rod. The active slide block and the driven slide block are centrally symmetrical about the rotation axis of the rotating plate. In this embodiment, the pneumatic push rod drives the active slide block to slide along the outer wall of the limiting slide rail. The sliding of the active slide block drives the active clamping block to slide synchronously, thereby realizing the sliding operation of the active clamping block.

[0009] Preferably, the rotation center of the rotating plate coincides with the midpoint of the rotating plate, and the lengths of the driving rod and the driven rod are equal. In this embodiment, it is convenient for the driven clamping block and the driving clamping block to slide synchronously relative to each other.

[0010] Preferably, the working surfaces of the active clamping block and the driven clamping block are concave, and the outer walls of the active clamping block and the driven clamping block are provided with anti-slip pads. In this embodiment, by setting the active clamping block and the driven clamping block with concave working surfaces, it is beneficial to improve the stability of workpiece clamping.

[0011] Preferably, the active clamping block forms a relative sliding structure with the passive clamping block through the active rod, the rotating plate, and the driven rod. In this embodiment, the active slide slides and drives the rotating plate to rotate through the active rod. The rotation of the rotating plate drives the passive slide to slide along the outer wall of the limiting slide rail through the driven rod. The sliding of the passive slide drives the passive clamping block to slide relative to the active clamping block synchronously, thereby performing a stable clamping operation on the workpiece.

[0012] Preferably, there are two sets of lifting cylinders, which are symmetrical about the push plate. The base plate is parallel to the push plate. In this embodiment, the lifting cylinders work to lift the lifting seat, and the lifting seat moves to lift the workpiece at the top of the push plate to a predetermined height, so as to avoid the workpiece from colliding during clamping, which could cause the workpiece to deviate or even fall off.

[0013] The beneficial effects of this utility model are:

[0014] 1. This centering clamping fixture, by setting a driven clamping block and an active clamping block, uses a pneumatic push rod to drive the active slide block to slide along the outer wall of the limiting slide rail. The sliding of the active slide block causes the active clamping block to slide synchronously. At the same time, the sliding of the active slide block drives the rotating plate to rotate through the active rod. The rotation of the rotating plate drives the driven slide block to slide along the outer wall of the limiting slide rail through the driven rod. The sliding of the driven slide block causes the driven clamping block and the active clamping block to slide synchronously relative to each other, thereby performing a stable clamping operation on the workpiece.

[0015] 2. This centering clamping fixture, by setting a push plate, the lifting cylinder drives the lifting seat to lift, and the movement of the lifting seat drives the workpiece at the top of the push plate to lift the workpiece to a predetermined height, so as to avoid the workpiece from colliding during clamping, causing the workpiece to deviate or even fall off.

[0025] Based on the above structure, the pneumatic push rod 3 drives the active slide 4 to slide along the outer wall of the limiting slide rail 5. The sliding of the active slide 4 drives the active clamping block 6 to slide synchronously. At the same time, the sliding of the active slide 4 drives the rotating plate 8 to rotate through the active rod 7.

The sliding of the driven slide 10 drives the driven clamping block 11 to slide synchronously with the active clamping block 6, thereby performing a stable clamping operation on the workpiece.

[0026] In one embodiment, the mounting base 1 has a "T" shaped cross-section, and the base plate 2 is provided in two sets, with the two sets of base plates 2 being centrally symmetrical about the center of the mounting base 1.

Then, the clamping position of the workpiece is adjusted. The lifting cylinder 12 operates to drive the lifting seat 13 to lift. The movement of the lifting seat 13 drives the workpiece at the top of the push plate 14 to lift the workpiece to a predetermined height, so as to avoid the workpiece from colliding during clamping, which could cause the workpiece to deviate or even fall off.
