Description

Technical Field

[0001] This utility model relates to the field of mandrel hoisting technology, and to a lifting detection device for identifying the front and back of a mandrel. Background Technology

[0002] In the mandrel production and assembly process, due to process requirements, one end of the mandrel usually has a stepped mounting surface. It is necessary to ensure that all mandrels are oriented in the same direction after hoisting; otherwise, it will lead to problems such as misalignment during subsequent assembly and processing errors. In traditional production, the identification of the front and back of the mandrel mainly relies on manual visual inspection, which has many drawbacks: 1. Manually judging the direction of each mandrel one by one can easily lead to human fatigue and misjudgment of direction over a long period of time, resulting in rework of hoisting and even equipment failure. 2. When manually intervening in the mandrel transfer process, improper operation can easily cause the mandrel to roll off, resulting in equipment damage or personnel injury. Utility Model Content

[0013] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0015] The following is a description of the embodiments and appendices. Figures 1-5 The technical solution of this utility model will be further described below.

[0016] Example 1 A lifting detection device for identifying the front and back of a spindle includes: a frame 1, a lifting device 2, and a detection device 3. The lifting device 2 includes a lifting cylinder 21 disposed at the front end of the frame 1, a mounting plate 22 disposed at the end of the piston rod of the lifting cylinder 21, and a lifting frame 23 disposed at the upper end of the mounting plate 22. The upper end of the lifting frame 23 is provided with a trapezoidal lifting groove 24. The detection device 3 includes a mounting crossbar 31 disposed at the front end of the frame 1, a rotary cylinder 32 disposed on the mounting crossbar 31, and a detector 33 disposed at the rotating end of the rotary cylinder 32.

[0017] like Figures 1-5 As shown, in actual use, because the upper end of the frame 1 is designed to be inclined, the spindle inside will automatically roll into the trapezoidal lifting groove 24 of the lifting device 2 under the action of gravity. The width of the trapezoidal lifting groove 24 is slightly larger than the diameter of the spindle, ensuring that a set of spindles can be stably supported each time. During the lifting phase, the piston rod of the lifting cylinder 21 extends, driving the mounting plate 22 and the lifting frame 23 to rise synchronously, lifting the mandrel in the trapezoidal lifting groove 24 away from the frame 1. After being lifted into position, the rotary cylinder 32 drives the detector 33 to rotate to the 90° detection position. The laser profile sensor lens is aligned with the end of the mandrel near the detection device 3. The front and back are determined by scanning the profile features. If a stepped mounting surface (a stepped structure with a sudden change in diameter) is identified, it is determined to be "front". If it is a flat end face (without steps), it is determined to be "back". After the test is completed, the rotary cylinder 32 drives the detector 33 to reset to the 0° clearance position to avoid interference with the mandrel during subsequent hoisting. The mandrel is then transferred to the next process by the hoisting mechanism. If the test result is positive, it is directly transferred; if it is negative, it is first rotated 180° by the steering mechanism before being transferred to ensure that the mandrels entering the next process are in the same direction.

[0018] The automated detection and orientation of this invention reduces hoisting rework caused by incorrect mandrel orientation; at the same time, the uniform mandrel orientation ensures the positioning accuracy of subsequent processes, reduces product scrap due to orientation deviation, and improves the quality consistency of the final product. The rotary cylinder 32 of the detection device 3 can drive the detector 33 to rotate and avoid collisions with the mandrel and lifting tools during the hoisting process. This protects the laser sensor and ensures continuous hoisting without interruption, thus improving the smoothness of the production line.

[0019] As a further preferred embodiment, the frame 1 is provided with a guide rail 11, and the guide rail 11 is provided with a first baffle 12 and a second baffle 13. The first baffle 12 is slidably disposed on the guide rail 11 and can be fixedly disposed on the guide rail 11 by a locking pin. The second baffle 13 is slidably disposed at the other end of the guide rail 11 and has an adjustment mechanism 4 disposed on its side end. The adjustment mechanism 4 includes a rotating seat 41 symmetrically disposed on the frame 1, a reciprocating screw 42 rotatably disposed on the rotating seat 41, and a drive seat 43 threadedly connected to the reciprocating screw 42. One end of the reciprocating screw 42 passes through one of the rotating seats 41 and the end is provided with a rotating handwheel 421. The upper end of the drive seat 43 is connected to the bottom of the second baffle 13.

[0020] Specifically, first, according to the length range of the mandrel to be tested, loosen the locking pin of the first baffle 12, slide it along the guide rail 11 to the approximate position (such as the limit point corresponding to the shortest length of the mandrel), insert the locking pin to fix it, second, turn the handwheel 421, and the reciprocating screw 42 drives the drive seat 43 to move through the thread transmission, so that the second baffle 13 moves closer to the first baffle 12, initially reducing the distance between the two baffles to slightly greater than the longest length of the mandrel; After initial positioning is completed, a single standard length mandrel is placed between the guide rails 11, with one end of it adhering to the working surface of the baffle 12; the handwheel 421 is rotated in the opposite direction to drive the baffle 2 13 to move slowly until it adheres to the other end of the mandrel. After positioning is completed, the mandrel axis is automatically aligned with the central axis of the trapezoidal lifting groove 24 of the lifting device 2. When changing to a different length of mandrel, simply turn the handwheel 421 to adjust the position of the second baffle 13. During the adjustment process, the self-locking characteristic of the reciprocating screw 42 ensures that the position of the second baffle 13 is stable, without the need for additional locking.

[0021] The baffle 12 and baffle 2 13 of this invention slide and adjust along the guide rail 11, which can flexibly adapt to mandrels of different lengths. This allows for multi-specification production needs to be met without replacing parts, significantly improving the equipment's versatility. The working surfaces of the baffles remain parallel and perpendicular to the mandrel conveying direction. Combined with the stable transmission of the reciprocating screw, this ensures stable axial positioning of the mandrel, improving the accuracy of subsequent inspection and lifting. As a further preferred embodiment, the front end of the frame 1 is provided with a slide rail 4, and the side end of the mounting plate 22 is provided with a linear bearing 221, which is slidably mounted on the slide rail 14.

[0022] Specifically, during the lifting operation, when the piston rod of the lifting cylinder 21 extends, the mounting plate 22 drives the lifting frame 23 to rise, and the linear bearings 221 on both sides slide synchronously along the slide rail 14. The slide rail 14 restricts the radial displacement of the linear bearings 221 through the rectangular cross section, retaining only the axial movement degree of freedom, and avoiding the mounting plate 22 from tilting due to uneven load.

[0023] As a further preferred embodiment, the guide rail 11 is provided in two sets, and the reciprocating lead screw 42 is disposed between the two sets of the guide rail 11.

[0024] Specifically, the symmetrical guidance of the double slide rails 11, combined with the low friction characteristics of the linear bearing 221, avoids positioning deviations caused by shaking of the mandrel during the lifting process, ensuring the accuracy of subsequent testing.

[0025] As a further preferred embodiment, the trapezoidal lifting groove 24 is provided in two sets, with the lower trapezoidal surface inclined downwards. The inclined trapezoidal surface prevents the mandrel from accidentally rolling off during the lifting operation.

[0026] As a further preferred embodiment, L-shaped placement blocks 51 are provided on the outer sides of both the first baffle 12 and the second baffle 13.

[0027] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
