Outside rail turnover mechanism

Abstract

The utility model relates to an outer rail turnover mechanism for solving the problem that the outer rail cannot be directly turned over due to the limited space above the original station. The mechanism comprises a base sliding unit arranged on the side of the original station of the outer rail, a lifting unit mounted on the base sliding unit, a turnover unit mounted on the output end of the lifting unit, and a jig mounted on the output end of the turnover unit through a quick-change structure. The bottom of the jig is provided with a clamping block matched with the shape of the inner cavity of the outer rail. The jig is driven by the base sliding unit to move horizontally into or out of the inner cavity of the outer rail to realize clamping and disengagement. Combined with the lifting action of the lifting unit and the 180-degree turnover of the turnover unit, the automatic turnover of the outer rail is realized beside the original station. The mechanism layout effectively utilizes the side space, and the replaceable jig can adapt to different models of outer rails.

Description

Technical Field

[0001] This utility model relates to the technical field of automated production equipment for slide rails, specifically an outer rail flipping mechanism. Background Technology

[0002] Currently, concealed sliding rails require a 180-degree rotation of the outer rail during production to complete double-sided operation. When there are fixed structures such as beams or pipes directly above the original workstation of the outer rail, traditional top-mounted direct-flipping mechanisms cannot be used due to spatial interference. Existing solutions either employ costly six-axis robots or move the outer rail a long distance to a dedicated flipping station, increasing both the number of steps and the cost. Therefore, there is an urgent need for a dedicated mechanism that can directly complete the flipping operation beside the original workstation. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an outer rail flipping mechanism.

[0004] This utility model provides the following technical solution: The outer rail tilting mechanism includes a base sliding unit, a lifting unit, a tilting unit, and a fixture. The base sliding unit is located to the side of the original working position of the outer rail; the lifting unit is mounted on the moving part of the base sliding unit; the tilting unit is mounted on the output end of the lifting unit; the fixture is detachably mounted on the output end of the tilting unit via a quick-change connection structure; the bottom of the fixture is provided with a locking block adapted to the shape of the inner cavity of the outer rail; the base sliding unit is configured to drive the fixture to move horizontally into the inner cavity of the outer rail to complete the locking, or to move out of the inner cavity of the outer rail to complete the disengagement.

[0005] Specifically, the quick-change connection structure includes a through hole on the top of the fixture, and bolts and nuts passing through the through hole and the output flange of the flip unit.

[0006] Specifically, the quick-change connection structure also includes a locating pin and a locating hole located between the flange and the top of the fixture.

[0007] Specifically, the base sliding unit includes a fixed base, a linear guide rail disposed on the fixed base, a movable slide table that slides with the linear guide rail, and a drive component that drives the movable slide table to reciprocate.

[0008] Specifically, the lifting unit includes a fixed housing, a push rod that can extend and retract axially relative to the housing, and a linear drive component for driving the push rod to extend and retract.

[0009] Specifically, the flipping unit includes a base, an output shaft rotatably supported within the base, a rotary drive component for driving the output shaft to rotate, and a positioning control mechanism for flipping the output shaft between 0 degrees and 180 degrees.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention avoids spatial interference issues directly above the original working position of the outer rail by placing the base sliding unit to the side of the original working position, thus enabling direct flipping beside the original working position. The base sliding unit drives the fixture to move horizontally into the inner cavity of the outer rail for clamping, achieving a lateral layout of the mechanism without requiring the outer rail to be moved a long distance out. The detachable quick-change connection structure and the locking blocks adapted to different outer rail inner cavity shapes allow the mechanism to adapt to different types of outer rails, avoiding the use of expensive six-axis robots. The entire mechanism, through the coordinated operation of the base sliding unit, lifting unit, and flipping unit, achieves automatic flipping of the outer rail, reducing intermediate transfer steps.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] like Figure 1-3As shown, the outer rail tilting mechanism includes a base sliding unit 1, a lifting unit 2, a tilting unit, and a fixture. The base sliding unit 1 is located to the side of the original working position of the outer rail 5; the lifting unit 2 is mounted on the moving part of the base sliding unit 1; the tilting unit is mounted on the output end of the lifting unit 2; the fixture is detachably mounted on the output end of the tilting unit via a quick-change connection structure; the bottom of the fixture is provided with a locking block 4 that matches the shape of the inner cavity of the outer rail 5; the base sliding unit 1 is configured to drive the fixture to move horizontally into the inner cavity of the outer rail 5 to complete the locking, or to move out of the inner cavity of the outer rail 5 to complete the disengagement; the lateral layout and the horizontal locking structure form the basis for completing the tilting operation beside the original working position.

[0016] In the above embodiment, the quick-connect structure includes a through hole 42 on the top of the fixture, and bolts 44 and nuts 41 passing through the through hole 42 and the output flange 43 of the flip unit. The quick-connect structure enables quick disassembly and installation of the fixture.

[0017] In the above embodiments, the quick-change connection structure also includes a hard alloy locating pin and a locating hole disposed between the flange 43 and the top of the fixture, in order to ensure the repeatability of the locating accuracy after the fixture is replaced.

[0018] The base sliding unit includes a fixed base 11, a linear guide rail 13 mounted on the fixed base, a movable slide 14 that slides with the linear guide rail, and a drive component 15 that drives the movable slide to reciprocate. It provides horizontal linear motion, allowing the fixture to move into the inner cavity of the outer rail to complete the clamping or move out to achieve disengagement, thereby realizing the avoidance function of the mechanism.

[0019] The lifting unit 2 includes a fixed housing, a push rod that can extend and retract axially relative to the housing, and a linear drive component that drives the push rod to extend and retract; the linear drive component is a servo electric cylinder; it provides vertical linear motion for lifting the outer rail for flipping or returning it to the conveying unit.

[0020] The flipping unit includes a base 3, an output shaft supported in the base by bearings, a rotary drive component 32 that drives the output shaft to rotate, and a positioning control mechanism that controls the flipping of the output shaft between 0 degrees and 180 degrees. The rotary drive component 32 is a servo motor, which directly drives the output shaft through a coupling. The positioning control mechanism includes a servo driver and an encoder built into the servo motor. By preset 0-degree and 180-degree position parameters in the servo driver, the encoder provides real-time feedback on the motor shaft position, forming a closed-loop control, thereby realizing the control of the flipping angle of the output shaft.

[0021] In the above embodiment, the conveying unit 6 is set at the original workstation and is used to horizontally convey the outer rail 5 along its length to a predetermined position. The conveying unit 6 adopts an intermittent motion mode, and its specific structure can refer to the prior art such as the stepping stable conveying mechanism disclosed in patent CN216888891U. The core of the stepping stable conveying mechanism consists of a machine base, a sliding support, a fixed support, and a drive component. Through the sequential action of the lifting and stepping mechanism, the intermittent motion cycle of picking up, stepping conveying, and putting down the workpiece is realized. This solution is a mature pure mechanical structure with the characteristics of high rigidity, stable operation, and reliable positioning, which fully meets the conveying requirements of the long strip workpiece outer rail 5 in this embodiment.

[0022] The working principle of this utility model is as follows: First, initialize the mechanism to the backward avoidance position. At this time, the base sliding unit 1 is in the rearmost position, the lifting unit 2 is in the raised state, and the flipping unit is in the 0-degree initial position.

[0023] A complete work cycle begins: The conveying unit 6 transports the outer rail 5 along the production line to the original position of the flipping mechanism. Once in place, the conveying unit 6 stops operating. The base sliding unit 1 drives the lifting unit 2, the flipping unit and the fixture on it to move forward as a whole. During the horizontal movement, the locking block 4 at the bottom of the fixture enters the inner cavity of the outer rail 5 to complete the locking. When the lifting unit 2 is activated, its push rod extends upward, vertically lifting the already clamped outer rail 5 away from the conveying unit 6 and raising it to the predetermined height; In the raised position, the flipping unit is activated, driving the fixture and outer rail 5 to rotate 180 degrees around the vertical axis; The lifting unit 2 moves in the opposite direction, the push rod retracts downward, and the outer rail 5, which has been flipped, is placed back to its original position on the conveying unit 6. The base sliding unit 1 drives the moving slide 14 to retreat to the avoidance position, and the flipping unit rotates back to the initial position of 0 degrees. The conveyor unit 6 restarts, moving the flipped outer rail 5 out of the workstation, ready to start a new work cycle.

[0024] When different models of outer rails need to be processed, the operator only needs to disassemble the bolts 44 and nuts 41 of the quick-change connection structure and replace them with a fixture with the corresponding clamp block 4 specification to quickly complete the product changeover.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
