Description

Technical Field

[0001] The utility model relates to the technical field of guide rails, and specifically relates to an automobile guide rail with adjustable guiding direction. Background Technique

[0002] An automobile guide rail is a device used to guide and support automobile components for linear reciprocating motion. The guide rail is usually made of metal or other materials and has longitudinal grooves or ridges for guiding and fixing machine components, special equipment, instruments, etc. According to the shape, the guide rail can be divided into T-shaped, U-shaped, etc. In addition, there is also a double-axis guide rail, which is a high-speed guide rail developed in Germany and is divided into an inner clamping type and an outer clamping type. The function of the guide rail is to support and guide the moving parts to make reciprocating linear motion in a given direction. It can achieve high-precision linear motion under high load and can bear a certain torque.

[0003] For example, the Chinese patent with the publication number CN215553085U discloses an automobile guide rail with adjustable guiding direction, including a bottom box. The top of the bottom box is movably connected with a box body. An adjusting mechanism is arranged in the inner cavity of the box body. The top of the adjusting mechanism penetrates through the box body and is bolted with a support platform. Guide rails are sequentially arranged on the top of the support platform from front to back. A sloping plate is bolted on the left side of the support platform, and a controller is bolted on the front side of the right side of the support platform. The utility model provides an automobile guide rail with adjustable guiding direction. Through the cooperation of a motor, a lead screw, a threaded sleeve, a connecting rod, a rotating shaft, a connecting plate and a connecting frame, the angle of the support platform is changed, so as to change the guiding direction of the guide rail body, avoiding that the user needs to move the whole device to change the direction of the guide rail body, preventing the waste of a large amount of manpower and material resources, improving the working efficiency of the user, and solving the problem that the guiding direction of the traditional automobile guide rail cannot be adjusted;

[0004] In the actual use process of the technical solution recorded in this scheme, when it is necessary to adjust the guide rail with a horizontal guiding direction to a vertical guiding direction, it is necessary for the user to visually observe and continuously adjust the guide rail with a horizontal guiding direction to achieve the purpose of a vertical guiding direction, which is rather inconvenient. At the same time, in the actual use process of this scheme, when the connecting frame rotates, it will drive the connecting plate and the rotating shaft at one end to rotate. When the rotating shaft rotates, it will cause an impact on the lead screw inside the box body, resulting in damage to the inside of the lead screw, and further affecting the normal operation of the lead screw. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automobile guide rail with adjustable guiding direction to solve the problems put forward in the above background technique.

[0006] In view of the above problems, the technical solution proposed by the utility model is:

[0007] An automobile guide rail with adjustable guiding direction includes a placement mechanism, a positioning mechanism and a rotating mechanism. The placement mechanism includes a base, an installation platform is rotatably arranged on the upper end surface of the base, and a pair of guide rails are arranged on the upper end surface of the installation platform. The positioning mechanism includes a horizontal plate and a vertical plate. The horizontal plate is fixedly arranged at the center of one side of the outer wall of the installation platform, and the vertical plate is fixedly arranged at the center of the front surface of the base. An infrared emitter and an infrared receiver are respectively connected to the bottom end of the horizontal plate and the upper end of the vertical plate. The infrared receiver receives the infrared rays emitted by the infrared emitter. An installation groove is opened at the center of the base. The rotating mechanism includes a power box. The power box is arranged inside the installation groove, and the outer wall of the power box is connected to the inner wall of the installation groove. A rotating shaft is rotatably connected inside the power box, the upper end of the rotating shaft is connected with a turntable, and the upper end of the turntable is connected to the bottom end of the installation platform.

[0008] Further, a worm gear is sleeved outside the rotating shaft, and a pair of connecting plates are connected to the inner bottom end of the power box near the worm gear. A worm is rotatably connected between the pair of connecting plates, and the worm meshes with the worm gear.

[0009] The beneficial effect of adopting the above further scheme is that through the cooperation of the worm gear and the worm, when the worm rotates, it is convenient to drive the worm gear meshing with it to rotate, thereby realizing the rotation of the rotating shaft.

[0010] Further, a second motor is connected to one side of the outer wall of one of the connecting plates, and the output end of the second motor is in transmission connection with the worm.

[0011] The beneficial effect of adopting the above further scheme is that by setting the second motor, when the second motor is started, it is convenient to drive the worm to rotate.

[0012] Further, second threaded holes are opened on both sides of the pair of guide rails, and a pair of sliding grooves are opened on the upper end surface of the installation platform. A pair of pressing plates are slidably connected inside the pair of sliding grooves. Second threaded holes are opened at the centers of the pair of pressing plates. Bolts are threadedly connected between the second threaded holes on the same side and the first threaded holes.

[0013] The beneficial effect of adopting the above further scheme is that through the cooperation of the second threaded holes and the first threaded holes, after the guide rail is placed on the installation platform, the pair of pressing plates are close to both ends of the guide rail, so that one side of the pressing plate fits with the end of the guide rail. Through the bolts, the second threaded holes and the first threaded holes, the connection between the guide rail and the pressing plates at both ends of it is realized, and thus the installation is completed.

[0014] Furthermore, a bidirectional lead screw is rotatably connected below a pair of sliding grooves inside the mounting table. Both ends of the bidirectional lead screw penetrate through the pressing plate and extend to the outside, and are threadedly connected to the pressing plate. T-shaped grooves are formed below the pair of bidirectional lead screws at the bottom end of the mounting table. A pair of T-shaped blocks are slidably connected inside the T-shaped grooves. The upper ends of the pair of T-shaped blocks are connected to the bottom ends of the pair of pressing plates. The beneficial effect of adopting the above further solution is that by setting the bidirectional lead screw, when the pair of bidirectional lead screws rotate, it is convenient for the pair of pressing plates threadedly connected to the outside of the pair of bidirectional lead screws to perform linear movement in opposite directions under the sliding action of the T-shaped blocks and the T-shaped grooves, so as to adapt to guide rails of different lengths.

[0015] Furthermore, a first mounting box and a second mounting box are respectively connected below the cross plate on both sides of the outside of the mounting table. One end of each of the pair of bidirectional lead screws penetrates through the first mounting box and extends to the inside, and a synchronous pulley is sleeved on each of them. A synchronous belt is wound between the pair of synchronous pulleys.

[0016] The beneficial effect of adopting the above further solution is that through the combined use of the synchronous pulley and the synchronous belt, when one of the bidirectional lead screws rotates, the other bidirectional lead screw will rotate under the transmission action of the synchronous pulley and the synchronous belt.

[0017] Furthermore, one end of one of the bidirectional lead screws away from the synchronous pulley penetrates through the second mounting box and extends to the inside. A first motor is connected to one side of the outer wall of the second mounting box. The output end of the first motor is in transmission connection with one of the bidirectional lead screws.

[0018] The beneficial effect of adopting the above further solution is that by setting the first motor, when the first motor works, it is convenient to realize the rotation of the bidirectional lead screw connected to its output end.

[0019] Compared with the prior art, the beneficial effect of the present utility model is that for the vehicle guide rail with adjustable guiding direction, when it is necessary to adjust the guide rail with a horizontal guiding direction to a vertical guiding direction, the second motor is started. The second motor makes the worm rotate, drives the worm gear meshing with the worm to rotate, and further realizes the rotation of the rotating shaft, drives the turntable to rotate and makes the mounting table rotate. Since the second motor is electrically connected to the infrared emitter through the controller, when the infrared emitter rotates to directly above the infrared receiver, the infrared receiver will receive the infrared rays emitted by the infrared emitter. At this time, a signal will be sent to the controller, and the controller will immediately turn off the second motor, and the turntable will stop rotating at this time. At this time, the mounting table and the pair of guide rails on the upper end are in a vertical state, avoiding the user having to visually observe and continuously adjust the guide rail with a horizontal guiding direction to achieve the purpose of a vertical guiding direction.
