Description

Technical Field

[0001] This utility model relates to a cross slide rail switching mechanism and a cross slide rail, belonging to the technical field of positioning devices. Background Technology

[0002] In flexible automotive manufacturing, the cross slide mechanism is widely used as a tooling buffer device. This mechanism achieves the sliding conversion of tooling in different directions through the staggered layout of longitudinal and transverse tracks, and requires a dedicated track switching mechanism to convert the longitudinal sliding track into the transverse sliding track.

[0003] However, existing track switching mechanisms mainly rely on rotating the track to overlap with the fixed track to achieve switching. When the rotating track reaches the docking position with the fixed track, the deviation between the rotating track and the overlapping fixed track in the height direction often causes the equipment to experience uneven movement and jamming when running along the track to the overlap point.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present invention, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0006] The technical solution provided by this utility model is as follows: A cross slide rail switching mechanism includes a turntable assembly, a linear cylinder, a rotating rail, rollers, and a clamping mechanism. The turntable assembly includes a rotating disk and a crank. The linear cylinder is hinged to the crank. When the telescopic shaft of the linear cylinder extends or retracts, it drives the rotating disk to rotate within a range of 0° to 90° via the crank. The rotating rail is installed on the rotating disk and can rotate synchronously with the rotating disk. The rollers are supported by a bracket and disposed on one side of the rotating disk. The rollers are used to support the rotating rail at the docking position. A positioning block is provided at the end of the rotating rail. The clamping mechanism is disposed beside the docking position of the rotating rail. When the rotating rail rotates to the docking position, the clamping mechanism can press against the positioning block.

[0007] Compared with the prior art, the technical solution provided by this utility model has the following advantages: This utility model uses a linear cylinder to drive a crank to rotate, thereby causing the rotating disk and rotating track to rotate within the range of 0° to 90°, achieving smooth docking between the rotating track and the fixed track; simultaneously, when the rotating track rotates to the docking position, the clamping mechanism applies vertical downward pressure to the rotating track through the positioning block, while the roller provides upward support force when the rotating track rotates to the docking position. Through the cooperation of the clamping mechanism and the roller, the position of the rotating track in the height direction can be adjusted, reducing the deviation between the rotating track and the fixed track at the overlapping position. In addition, the clamping force of the clamping mechanism acting on the positioning block is perpendicular to the sliding direction of the equipment on the track, which can prevent displacement at the docking point.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, it also includes a limiting device, which includes a first movable limiting block, a second movable limiting block, a first limiting stop block, and a second limiting stop block. The first movable limiting block and the second movable limiting block are disposed on the crank and can rotate synchronously with the crank. The first movable limiting block and the first limiting stop block are used to limit the rotation disk to stop at the 0° position, and the second movable limiting block and the second limiting stop block are used to limit the rotation disk to stop at the 90° position.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the setting of the limiting device can accurately limit the rotation of the rotating disk to the stop position. When the crank drives the rotating disk to rotate to the preset 0° docking position, the first movable limiting block will contact the first limiting stop block to prevent the rotating disk from continuing to rotate. When the crank drives the rotating disk to rotate to the preset 90° docking position, the second movable limiting block abuts against the second limiting stop block to prevent the rotating disk from continuing to rotate.

[0011] Furthermore, the collision contact surface between the first movable limiting block and the first limiting stop block is made of polyurethane buffer layer, and the collision contact surface between the second movable limiting block and the second limiting stop block is made of polyurethane buffer layer.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the polyurethane buffer layer can absorb impact kinetic energy.

[0013] Furthermore, the clamping mechanism includes a clamping cylinder, a clamping arm, and a clamping block. One end of the clamping arm is hinged to the clamping cylinder, and the clamping block is installed at the other end of the clamping arm. The clamping cylinder can drive the clamping arm to rotate around the hinge axis, so that the clamping block clamps or releases the positioning block.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the clamping mechanism drives the clamping arm to rotate through the clamping cylinder, thereby clamping or releasing the positioning block. The structure is simple, the operation is convenient, and the stability and reliability of track switching are improved.

[0015] Furthermore, the bottom surface of the rotating track is provided with a guide slope. When the rotating track passes over the roller during rotation, the guide slope can guide the rotating track to rotate smoothly to the docking position, further ensuring the smooth docking of the rotating track and the fixed track.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the guide ramp can reduce the impact force when the rotating track contacts the roller.

[0017] Furthermore, the bottom surface of the rotating track is provided with a guide slope. When the rotating track passes over the roller during rotation, the guide slope can ensure that the rotating track rotates smoothly to the docking position.

[0018] The advantage of adopting the above-mentioned further solution is that it ensures a smooth connection between the rotating track and the fixed track.

[0019] A cross slide rail includes a horizontal fixed rail and a vertical fixed rail, and also includes the cross slide rail switching mechanism. The cross slide rail switching mechanism is located at the intersection of the horizontal fixed rail and the vertical fixed rail. The turntable assembly, linear cylinder and clamping mechanism are all mounted on a base. The base is fixedly connected to the horizontal fixed rail or the vertical fixed rail. The rotating rail can switch between the horizontal fixed rail and the vertical fixed rail under the drive of the turntable assembly.

[0020] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: The cross slide rail switching mechanism and cross slide rail provided by this utility model can effectively solve the problem of deviation between the rotating rail and the overlapping fixed rail in the height direction in the prior art, avoid the frequent unsmoothness when the equipment runs along the rail to the overlapping point, reduce jamming, and thus significantly improve the operating efficiency and stability of the equipment.

[0031] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0032] like Figures 1-4 As shown, a cross slide rail switching mechanism includes a turntable assembly 100, a linear cylinder 200, a rotating rail 300, rollers 400, and a clamping mechanism 500. The turntable assembly 100 includes a rotating disk 101 and a crank 102. The linear cylinder 200 is hinged to the crank 102. When the telescopic shaft of the linear cylinder 200 extends or retracts, it drives the rotating disk 101 to rotate within the range of 0° to 90° via the crank 102. The rotating rail 300 is mounted on the rotating disk 101 and can rotate synchronously with the rotating disk 101. The rollers 400 are connected via... A bracket 401 supports and is disposed on one side of the rotating disk 101. The roller 400 is used to support the rotating track 300 at the docking position. When the rotating track 300 passes over the roller 400 during rotation, the supporting surface of the roller 400 slides in contact with the bottom surface of the rotating track 300. A positioning block 301 is provided at the end of the rotating track 300. The pressing mechanism 500 is disposed beside the docking position of the rotating track 300. When the rotating track 300 rotates to the docking position, the pressing mechanism 500 can press against the positioning block 301.

[0033] The linear cylinder 200 drives the rotating track 300 to rotate and rotates above the roller 400 to the docking position. When the rotating track 300 rotates to the docking position, the pressure head of the pressing mechanism 500 can press down on the positioning block 301 from top to bottom. The roller 400 supports the rotating track 300 from below.

[0034] The cross slide track switching mechanism also includes a limiting device, which includes a first movable limiting block 601, a second movable limiting block 602, a first limiting stop 603, and a second limiting stop 604. The first movable limiting block 601 and the second movable limiting block 602 are disposed on the crank 102 and can rotate synchronously with the crank 102. The first movable limiting block 601 and the first limiting stop 603 are used to limit the rotary disk 101 to the 0° position (reference). Figure 1 The second active limit and the second limit stop 604 are used to limit the rotating disk 101 to a 90° position (see reference). Figure 4 (The cessation of)

[0035] The clamping mechanism 500 includes a clamping cylinder 501, a clamping arm 502, and a clamping block 503. One end of the clamping arm 502 is hinged to the clamping cylinder 501, and the clamping block 503 is installed at the other end of the clamping arm 502. The clamping cylinder 501 can drive the clamping arm 502 to rotate around the hinge axis, so that the clamping block 503 clamps or releases the positioning block 301.

[0036] The bottom surface of the rotating track 300 is provided with a guide slope 302. When the rotating track 300 passes over the roller 400 during rotation, the guide slope 302 can ensure that the rotating track 300 rotates smoothly to the docking position.

[0037] like Figure 5 and Figure 6 As shown, a cross slide rail includes a horizontal fixed rail 700 and a vertical fixed rail 800 arranged vertically, and also includes the cross slide rail switching mechanism. The cross slide rail switching mechanism is located at the intersection of the horizontal fixed rail 700 and the vertical fixed rail 800. The turntable assembly 100, the linear cylinder 200 and the clamping mechanism 500 are all mounted on a base. The base is fixedly connected to the horizontal fixed rail 700 or the vertical fixed rail 800. The rotating rail 300 can switch between the horizontal fixed rail 700 and the vertical fixed rail 800 under the drive of the turntable assembly 100.

[0038] Taking the switching of the rotating track 300 from the horizontal fixed track 700 to the vertical fixed track 800 as an example, the working method of the cross slide track switching mechanism of this utility model is as follows:

[0039] On the transverse track (i.e., at the 0° position), the linear cylinder 200 is in the retracted state, and the crank 102 drives the rotary disk 101 to stop on the transverse track. At this time, the first movable limit block 601 and the first limit stop block 603 abut against each other, and at the same time, the pressing block 503 of the pressing mechanism 500 tightly presses the positioning block 301.

[0040] When the switching is triggered, the clamping cylinder 501 starts to operate, driving the pressure arm 502 to lift, causing the pressure block 503 to disengage from the positioning block 301. Subsequently, the linear cylinder 200 starts and extends, pushing the crank 102 to rotate clockwise (from a top view), causing the rotating disk 101 and the rotating track 300 to rotate synchronously.

[0041] During rotation, when the rotating track 300 rotates to the position of the roller 400, the guide slope 302 on its bottom surface contacts the top surface of the roller 400. Under the guidance of the slope, a smooth transition is achieved to the docking position. When the second movable limit block 602 abuts against the second limit stop block 604, the rotating disk 101 stops rotating, and the end of the rotating track 300 overlaps with the longitudinal fixed track 800. At this time, the roller 400 provides an upward support force.

[0042] During the reset process, the linear cylinder 200 retracts and drives the rotating disk 101 to rotate counterclockwise, and the rotating track 300 also rotates synchronously. When the first movable limit block 601 abuts against the first limit stop block 603, the rotating track 300 returns to the 0° position, and the end of the rotating track 300 overlaps with the transverse fixed track 700. At this time, the roller 400 provides upward support force, and at the same time, the pressure block 503 of the pressing mechanism 500 presses the positioning block 301, locking the rotating track 300 at the 0° position.

[0043] The cross slide rail switching mechanism and cross slide rail provided by this utility model can effectively solve the problem of deviation between the rotating rail 300 and the overlapping fixed rail in the height direction in the prior art. It avoids the frequent unsmoothness when the equipment runs along the rail to the overlapping point, reduces jamming, and thus significantly improves the operating efficiency and stability of the equipment.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
