Description

Technical Field

[0001] The utility model belongs to the technical field of processing fixtures, and in particular relates to a pneumatic fixture device for impact specimen marking. Background Art

[0002] In the process of pneumatic marking, the fixation and positioning of the impact specimen has always been the key link to ensure the quality of marking. In the traditional marking method, the staff usually use a manual clamp to clamp the impact specimen and fix the specimen by tightening the side top bolts on the clamp. However, in the actual operation process, this traditional manual clamp has some inherent defects. Specifically, when the pneumatic marking machine performs impact marking on the impact specimen, due to the impact force, the fastening bolts on the clamp tend to loosen themselves during the impact process. This loosening not only affects the accuracy and stability of the marking, but also may cause the workpiece to shift or rotate during the marking process. These problems will eventually cause the marking font to be blurred, deformed or offset, seriously affecting the marking quality and appearance of the product. In addition, when using traditional manual clamps for pneumatic marking operations, the staff needs to pay attention to the tightening state of the clamp at all times. During the marking process, they have to frequently tighten the loose bolts by hand, which not only increases the labor intensity of the operator, but also reduces production efficiency. At the same time, there are certain safety hazards in the operation of manually tightening the bolts, and improper operation may cause harm to the staff. Utility Model Content

[0018] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] A pneumatic fixture device for impact specimen marking, such as Figure 1 , 2 As shown, it includes a bracket 1, a cylinder 2, a fixed pressure block 3, a movable pressure block 4 and a clamping pressure block 5, wherein the bracket 1 is a frame structure with a working platform 6, the bottom of the working platform 6 is provided with a cylinder 2, and the upper surface of the working platform 6 is provided with a fixed pressure block 3, a movable pressure block 4 and a clamping pressure block 5.

[0020] like Figure 1 , 2 As shown, the fixed pressure block 3, the movable pressure block 4 and the clamping pressure block 5 form an inclined wedge structure through the guide groove 7, wherein the fixed pressure block 3 is a reverse side block, the movable pressure block 4 is an inclined wedge, and the clamping pressure block 5 is a slider; the fixed pressure block 3 is fixed to one end of the upper surface of the working platform 6 by a bolt 8; the bottom of the working platform 6 is provided with a through circular hole, and the cylinder rod 10 of the cylinder 2 is connected to the bottom of the movable pressure block 4 through the circular hole. The cylinder rod 10 moves up and down perpendicular to the upper surface of the working platform 6, and the clamping pressure block 5 moves horizontally along the upper surface of the working platform 6, and the vertical movement is converted into horizontal movement through the above-mentioned inclined wedge structure.

[0021] In order to ensure that the wedge structure in the device can operate normally, the upper surface of the working platform 6 and the lower surface of the clamping block 5 are both made of wear-resistant material, and the guide groove 7 is made of wear-resistant material, which can be 42CrMo or other materials.

[0022] The device also includes a valve and an air compressor. The bottom of the cylinder is connected to the air compressor through an air pipe. The air pipe is provided with a valve for controlling air pressure. The valve is a two-position three-way reversing valve.
