Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to an automatic core shaft turning mechanism. Background Art

[0002] In automated production machinery, especially in situations where multi-faceted processing or assembly of parts is required, it is necessary to cooperate with the mandrel automatic flipping mechanism to clamp and flip the products on the assembly line. Usually, the clamping assembly and flipping assembly located above the assembly line cooperate to clamp and flip the products, while the traditional flipping assembly includes a set of gears, levers, rollers or other mechanical parts that work together to flip the workpiece. This mechanism needs to be precisely designed to ensure that the workpiece can be flipped smoothly and accurately at the required angle. There are too many structures that need to be coordinated and linked. During the product flipping process, if one of the structures deviates, the product flipping fails and the product flipping is damaged, reducing the accuracy of the product's automated production flipping operation and the yield rate of automated product processing.

[0003] Therefore, the utility model provides a core shaft automatic turning mechanism with an adjustable headrest. Utility Model Content

[0004] The utility model aims to provide a mandrel automatic turning mechanism to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A mandrel automatic turning mechanism comprises two mounting base plates respectively fixed to two sides of the assembly line, and a supporting transverse plate fixed to the middle of the two mounting base plates and higher than the bottom surface of the base plates, wherein a turning cylinder is installed in the middle of the two mounting base plates through a cylinder fixing plate, and is fixedly connected to the supporting transverse plate through a mounting plate on the output shaft of the turning cylinder;

[0007] Positioning and clamping cylinders are respectively provided at the connection points between the mounting plate and the supporting cross plate, and the pneumatic rods of the positioning and clamping cylinders are connected with clamping arms, and the products are clamped and positioned by the clamping arms. The input end of the positioning and clamping cylinders is connected with a photoelectric incoming material sensing sensor that senses the product position.

[0008] Furthermore, an L-shaped support plate is provided in the middle of the two mounting base plates, and the cylinder fixing plate is fixedly installed on the inner side of the support plate. The positioning and clamping cylinder installed on the supporting cross plate is firmly supported above the assembly line through the mounting plate to maintain stability in clamping and flipping the product.

[0009] Furthermore, a rotating shaft seat is provided on the outer side of the middle part of the mounting plate, and is connected to the output end of the flip cylinder through the rotating shaft seat. The rotating shaft seat cooperates with the core shaft of the output end of the flip cylinder to connect. When the core shaft drives the supporting cross plate to rotate to flip the product, wear between the mounting plate and the flip cylinder is avoided while maintaining the stability of the mounting plate rotated by the flip cylinder.

[0010] Furthermore, the clamping end of the clamping arm is located above the assembly line of two bottom plate brackets and is consistent with the height of the products conveyed on the assembly line. The clamping arm is supported above the assembly line by the bottom installation, and can move horizontally to clamp and position the products on the assembly line when the positioning clamping cylinder is running.

[0011] Furthermore, the positioning and clamping cylinders and the clamping arms are respectively provided with two groups, and the two groups of positioning and clamping cylinders and clamping arms are symmetrically arranged on the left and right sides of the supporting cross plate. When the product is clamped, positioned and flipped, the two groups of positioning and clamping cylinders operate simultaneously and the two clamping arms operate relatively to each other at the same time, so that the clamping ends of the product and the two clamping arms are relatively clamped and positioned, thereby maintaining the firm positioning of the product.

[0012] Furthermore, the mounting plate and the supporting cross plate are U-shaped to fix the positioning clamping cylinder, and the U-shaped mounting plate is fixed to the supporting cross plate, thereby improving the firmness of the mounting of the positioning clamping cylinder.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The automatic turning mechanism of the mandrel supports the fixed positioning clamping cylinder and the turning cylinder above the assembly line by installing the cooperation of the bottom plate and the supporting cross plate, and connects the photoelectric incoming material sensing sensor to the input end of the fixed positioning clamping cylinder. The photoelectric incoming material sensing sensor senses the product detection on the assembly line, and when the photoelectric incoming material sensing sensor senses that the product is located in the area to be clamped, the fixed positioning clamping cylinder operates to move the mechanical arm toward the product position, clamps and fixes the product, and after the fixed positioning clamping cylinder clamps and fixes the product, it feeds back the signal to the turning cylinder, the turning cylinder operates, and the mandrel on the turning cylinder rotates accordingly, and the mandrel rotates 180 degrees to the supporting cross plate, thereby achieving the effect of 180-degree turning of the product conveyed on the assembly line, using simple structural coordination, there is no need to use gears and other structures to coordinate the turning, thereby avoiding the probability of deviation when the gears rotate, achieving the purpose of stable clamping and turning of the product, improving the accuracy of the automated production line for the automated production of products, and thereby improving the yield rate of the automated production of products.

[0023] A rotating shaft seat 9 is provided on the outer side of the middle part of the mounting plate 5, and is connected to the output end of the flip cylinder 4 through the rotating shaft seat 9. The rotating shaft seat is connected with the core shaft of the output end of the flip cylinder 4.

[0024] The clamping end of the clamping arm 7 is located above the assembly line of the two mounting base plate 1 brackets and is consistent with the height of the product 10 conveyed on the assembly line.
