Description

Technical Field

[0001] The utility model belongs to the technical field of hinge production equipment, and in particular relates to a tooling for quality inspection. Background Art

[0002] Small parts (such as invisible hinges) generally need to be inspected after production. During the inspection, a tool is needed to clamp the workpiece. The clamping tool in the prior art has a complex structure and is mostly a fixture for clamping a single workpiece. It cannot clamp and fix workpieces in batches, which is inefficient and not conducive to production. Therefore, a tool for quality inspection is needed to solve the above technical problems. Utility Model Content

[0003] In view of the above-mentioned defects existing in the prior art, the utility model provides a tool for quality inspection, including a placement plate, a plurality of limit blocks are arranged on the placement plate in a matrix, and grooves are provided between adjacent limit blocks in the same row, and a clamping piece is provided in the groove;

[0004] The clamping member includes two clamping blocks, which are arranged on both sides of the groove. The sides of the two clamping blocks facing each other are connected to the side walls of the corresponding grooves through springs. The upper parts of the sides of the two clamping blocks facing each other are inclined slopes, and the two slopes form a tapered channel that is wide at the top and narrow at the bottom. A pressing block is arranged in the tapered channel, and the length of the pressing block is equal to the width of the upper end of the tapered channel when the spring is in a free state. A push rod is fixedly connected to the lower surface of the pressing block, and a telescopic rod is connected to the lower end of the push rod. The fixed end of the telescopic rod is fixed to the lower surface of the placement plate, and the telescopic end of the telescopic rod extends into the groove and is connected to the push rod. The workpiece to be inspected is placed in the space between the limit block and the clamping member, the telescopic rod is contracted, the pressure plate is pressed down, and it moves down along the tapered channel to open the tapered channel. The two clamping blocks move back to back in the groove, the spring is compressed, and the clamping block and the corresponding limit block clamp the workpiece, so that the workpiece can be limited. When the quality inspection is completed, the telescopic rod is extended, the pressing block moves up, and under the action of the spring, the two clamping blocks are reset and released to clamp the workpiece, making it easy to take out the workpiece.

[0005] Preferably, the limit block is in an I-shape, and a limit strip protruding upward is provided at the center of the limit block, which prevents the workpieces on both sides of the limit block from contacting and interfering with each other, and further improves the clamping effect.

[0006] Preferably, the two inclined surfaces are provided with guide grooves with a T-shaped cross section, and the two ends of the corresponding inclined surface of the pressing block are provided with T-shaped guide blocks matching the guide grooves, and the two guide blocks are respectively slidably arranged in the corresponding guide grooves. The setting of the guide groove can guide the pressing block to press down or rise, ensuring that the upward and downward movement of the pressing block can change the horizontal distance between the two clamping blocks.

[0007] Preferably, the telescopic rod is a cylinder or an electric push rod.

[0008] The utility model also includes other components that enable a quality inspection tool to be used normally, such as the control components of the electric push rod and the control components of the cylinder, which are conventional technical means in the field. In addition, the devices or components not limited in the utility model, such as springs, electric push rods, cylinders, etc., all adopt conventional technical means and conventional equipment in the field.

[0009] Working principle: Place the workpiece to be inspected in the space between the limit block and the clamping piece, retract the telescopic rod, press the pressure plate down, move down along the tapered channel, open the tapered channel, and move the two clamps back to back in the groove. The spring is compressed, and the clamps and the corresponding limit blocks clamp the workpiece, thus achieving the limit of the workpiece. When the quality inspection is completed, the telescopic rod is extended, the pressure block moves up, and the two clamps are reset under the action of the spring, and the clamping of the workpiece is released, making it easy to take out the workpiece.

[0010] In the above process, the limit strip prevents the workpieces on both sides of the limit block from contacting and interfering with each other, further improving the clamping effect. The guide groove can guide the pressing block to press down or rise, ensuring that the up and down movement of the pressing block can change the horizontal distance between the two clamping blocks, thereby ensuring the clamping effect.

[0011] The beneficial effects of the utility model are as follows: the structure is simple and reasonable, batches of workpieces can be clamped and fixed, thereby efficient quality inspection is carried out, the workpieces are easy to install and disassemble on the placement plate, the clamping effect is good, and the work efficiency is high.
