Detailed Description

The following description of the embodiments refers to the accompanying drawings, which are included to illustrate specific embodiments in which the invention may be practiced.

As shown in fig. 1, the present embodiment discloses a fixture device for a grinding machine, the fixture device for a grinding machine includes a mounting base 1, a driving mechanism 2, a slider 3, a first universal bearing 4, an upper support rod 6 and two pressure wheel arms 5, the driving mechanism 2 is connected to the slider 3 and is used for driving the slider 3 to slide on the mounting base 1, the first universal bearing 4 is disposed in the slider 3, the upper support rod 6 is connected to the mounting base 1, the two pressure wheel arms 5 are both pivoted to the upper support rod 6, the bottoms of the two pressure wheel arms 5 are respectively connected to two ends of the first universal bearing 4, and a workpiece to be machined is clamped between the tops of the two pressure wheel arms 5.

The driving slide block 3 slides back and forth on the mounting base 1 through the driving mechanism 2, and the first universal bearing 4 and the two pressure wheel arms 5 are driven to move back and forth. When a workpiece is to be machined in a clamping mode, the driving mechanism 2 drives the sliding block 3 to move forwards, the bottoms of the first universal bearing 4 and the two pressure wheel arms 5 are driven to move forwards, the two pressure wheel arms 5 realize swinging rotation through the upper supporting rod 6, the tops of the two pressure wheel arms 5 move in the opposite direction of the first universal bearing 4, namely the tops of the two pressure wheel arms 5 move backwards, the tops of the two pressure wheel arms 5 realize clamping of the workpiece to be machined, the pressure of the two pressure wheel arms 5 in the clamping process of the workpiece to be machined can be automatically adjusted through the first universal bearing 4, the contact force of the pressure wheel arms 5 is guaranteed to be balanced, the workpiece to be machined is uniformly stressed, the outer ring groove diameter is uniformly ground, and defective products cannot be generated. Meanwhile, the fixture device of the grinding machine is simple in integral structure and convenient to maintain, and the pressure ratio does not need to be adjusted when the driving mechanism 2 is driven to use, so that the machining efficiency is improved.
