Description

Technical Field

[0001] The utility model relates to the technical field of pin sleeve processing and detection, in particular to a high-precision detection device for pin sleeve processing. Background Art

[0002] Pin sleeves are hard steel nests that strengthen the positioning pin holes. There are several types of pin sleeves, including positioning pin sleeves, which are hard steel nests that strengthen the positioning pin holes, and cylindrical pin sleeves. In the cycloid pinwheel planetary transmission mechanism, they are sleeved on the cylindrical pin in the pin hole output mechanism and mesh with the cylindrical surface of the corresponding cylindrical pin hole on the cycloid wheel. They are widely used.

[0003] The existing high-precision detection device for pin sleeve processing has the problem of low work efficiency when it is used when manually placing each pin sleeve on the workbench one by one and performing detection, which is not conducive to batch detection and has high detection cost; secondly, when automatic feeding detection is adopted, since the pin sleeve is a small and light product, the pin sleeve is required to be aligned for positive projection, and the pin sleeve is required to be fed to the detection position at intervals, and the processing position of the workpiece cannot be detected in time, resulting in damage to the pin sleeve workpiece during the processing process, and the risk of breakage is easy to occur. Therefore, a high-precision detection device for pin sleeve processing is designed to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a high-precision detection device for pin sleeve processing, which is conducive to automatic limiting and real-time detection of different models of processing pin sleeves, preventing unstable fixation of the pin sleeve before processing, with high stability, and further improving the overall processing quality.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A high-precision detection device for pin sleeve processing is designed, including a processing machine base, the upper end of the processing machine base is fixedly connected to a base plate, the upper surface of the base plate is annularly arranged with a plurality of baffles, a gear is rotatably installed on the inner side of the baffle, an L-shaped plate is slidably arranged on the inner side of the baffle, one end of the L-shaped plate is rotatably connected to a linkage block, the upper surface of the L-shaped plate is provided with a first rack plate meshing with the gear, the upper part of the L-shaped plate is inserted and slidably installed with a limiting frame, the bottom end of the limiting frame is provided with a second rack plate, the second rack plate meshes with the gear, the bottom end of the L-shaped plate is fixedly connected to an extension plate, the outer surface of the extension plate is fixedly connected to a cross bar, the cross bar and the baffle are movably arranged, and the cross bar is located between the baffle and the extension plate and is movably sleeved with a first spring.

[0007] Preferably, a mesh grille is provided at one end of the processing machine base, a through opening is provided on the inner side of the processing machine base, and the mesh grille matches the through opening.

[0008] Preferably, a material presenting seat is fixedly mounted on the upper end of the processing machine base, a limiting opening is opened in the middle of the material presenting seat, a pin sleeve workpiece is arranged on the inner side of the limiting opening, and a plurality of limiting openings are opened in a ring shape in the middle of the material presenting seat.

[0009] Preferably, a plurality of limiting blocks are equidistantly arranged in a ring shape on the upper surface of the material holder and on the outer edge of the limiting opening.

[0010] Preferably, a cooling air pump is fixedly installed on one side of the processing machine base, the bottom end of the cooling air pump is fixedly connected to a delivery air pipe, and an air jet sleeve is provided on the upper part of the processing machine base, and the delivery air pipe is connected to the air jet sleeve.

[0011] The utility model proposes a high-precision detection device for pin sleeve processing, which has the following beneficial effects:

[0012] The pin sleeve to be processed is placed between multiple limit blocks and enters the limit opening by personnel. When the processing tool comes down, it slides with the outer wall of the limit block, pushing the linkage block to move. With the movement of the linkage block, the L-shaped plate is driven to slide outward in the slide groove, so that the gear rotates counterclockwise under the drive of the first rack plate, and then the second rack plate is driven to move under the rotation of the gear, so that multiple limit frames slide in the same direction on the L-shaped plate, so that multiple limit frames simultaneously limit the middle of the pin sleeve workpiece. The first spring reset pushes the extension plate to drive the L-shaped plate to slide and reset in the slide groove, thereby releasing the clamped workpiece and ensuring the stability of the processing. When the cross bar does not reach the original position at the bottom end, it is detected that the position of the workpiece is tilted or other conditions are present, and the processing should be stopped and re-placed. The cooling gas is released by the cooling air pump and transported to the jet sleeve through the delivery air pipe. When the tapping tool taps the pin sleeve workpiece, the cooling gas can be sprayed in time to cool the upper mouth of the pin sleeve workpiece, thereby reducing damage to the pin sleeve during processing and ensuring the processing effect.

[0013] Compared with the existing technology, the utility model has a reasonable structure and strong practicality. It is conducive to automatic limiting and real-time detection of processing pin sleeves of different models, preventing unstable fixation of the pin sleeves before processing, and has high stability, further improving the overall processing quality.
