Description

Technical Field

[0001] The proposed implementation scheme relates to the field of automotive parts processing equipment technology, and in particular to multi-level workstation lifting and transmission equipment. Background Technology

[0002] Existing automotive parts processing is mostly manual, resulting in low production efficiency. While basic auxiliary equipment is sometimes used, its automation level is relatively low. Furthermore, this basic equipment cannot adjust the horizontal or vertical position of the automotive parts being processed, leading to inconvenience in parts processing and the inability to automatically change tire membranes. This technical solution provides a multi-layer lifting and transmission device with horizontal and vertical transmission mechanisms, enabling horizontal and vertical transmission of the tire membrane. It can also accommodate double-layer tire membranes; the upper membrane is being welded while the lower membrane awaits the command to move upwards. This significantly improves upon traditional automotive parts processing auxiliary equipment, effectively increasing processing efficiency and avoiding errors caused by manual operation.

Both ends of the second shaft and the third shaft are provided with gears, and are respectively connected to the rack through gear meshing. The speed-multiplying chain is mounted on the tire membrane base plate support frame. The speed-multiplying chain and the tire membrane are driven by a first motor.

[0021] In the following description of the embodiments, reference will be made to the accompanying drawings, which form a part of the following description, and specific embodiments that may be implemented are shown by way of example in the drawings. It should be understood that other embodiments may be used and structural changes may be made without departing from the scope of the various embodiments.

[0022] Now refer specifically to the representative implementation scheme illustrated in the accompanying drawings.

[0023] Example 1, see appendix Figures 1-6 The diagram shows the structure of a multi-layer lifting and transmission device, including a frame body 1 with a double-layer mold changing position 12, which can hold at least two layers of molds 26. The workpieces inside the molds 26 are pressed and fixed by a flip-up pressure fixture, and horizontal and vertical transmission is achieved through a horizontal transmission mechanism 2 and a vertical transmission mechanism 3. The horizontal transmission mechanism 2 is installed inside the frame body 1 and has a double-speed chain 21 and a first motor 23. The first motor 23 is connected to a horizontal transmission shaft 25 through a horizontal transmission gear sprocket 24, and the gears at both ends of the horizontal transmission shaft 25 are engaged with the double-speed chain 21. Both ends of the double-speed chain 21 are connected to the horizontal transmission shaft 25, thereby achieving the driving effect of the double-speed chain 21. Since the pressure fixture for mounting the molds 26 is placed on the double-speed chain 21, the horizontal position of the transmission molds 26 is controlled. The vertical transmission mechanism 3 is also installed inside the frame body 1, and is equipped with a tire membrane base plate support frame 31, a lifting mounting plate 34 and a second motor 35. The tire membrane base plate support frame 31 is located between the double speed chains 21 on both sides of the frame body 1. At the same time, the tire membrane base plate support frame 31 is equipped with a lifting support platform 32 for supporting the press. Under the action of the support platform drive cylinder 33, the lifting support platform 32 can lift the press so that it no longer squeezes the double speed chain 21, and at the same time avoids adverse effects on the double speed chain 21 when welding automotive parts.

[0024] The lifting mounting plate 34 is located at the four corners of the frame body 1. The second motor 35 is located below the membrane base support frame 31. The second motor 35 is connected to the second shaft 311 and the third shaft 313 via the first shaft 39, and corresponding gears and sprockets are provided between the shafts. The lifting mounting plate 34 is equipped with a guide rail 36 and a rack 37. The guide rail 36 is matched and connected to the guide sliders 38 installed on both sides of the membrane base support frame 31. The rack 37 on the lifting mounting plate 34 is meshed with the gears at both ends of the second shaft 311 and the third shaft 313. Under the action of the second motor 35, the shafts are driven to move vertically up and down along the direction of the rack 37. Therefore, the membrane base support frame 31 will move up and down simultaneously with the assistance of the guide rail 36, which in turn causes the membrane 26 and the press to move up and down as well.

[0025] In summary, under the action of the horizontal transmission mechanism 2 and the vertical transmission mechanism 3, the diaphragm 26 and the press can achieve horizontal and vertical movements, thereby optimizing the welding processing effect of automotive parts. Meanwhile, blocking switches 16 and sensors 15 are respectively provided on both ends of the diaphragm base plate support frame 31 to prevent the diaphragm 26 and the press from overstepping their designated positions during transmission. The frame body 1 is equipped with a workpiece loading / unloading operation position 11 for placing and processing workpieces, and a mold changing position 12 for changing the diaphragm 26 and the press. It also includes a protective plate 17, a light grating 18, an emergency stop button 19, and an automatic operation switch 110 for human safety.

[0026] The working principle of this technical solution is as follows (see appendix). Figure 1 As shown, the multi-level lifting and transmission equipment includes a frame body 1, a horizontal transmission mechanism 2, and a vertical transmission mechanism 3.

Protective plates 17 are installed on the top and rear sides of the frame body 1, and protective plates 17 are also installed on both sides of the lower mold-changing position 14. The upper mold-changing position 13 and the lower mold-changing position 14 are equipped with high-strength acrylic protective plates. At least two part-loading / placing operation positions 11 are provided, arranged opposite each other, and equipped with a light grid 18 to detect whether an object has entered the equipment. Emergency buttons 19 and automatic operation switches 110 are located on both sides of each part-loading / placing operation position 11. (See appendix) Figure 5As shown, the horizontal transmission mechanism 2 is installed inside the frame body 1. The horizontal transmission mechanism 2 includes a double-speed chain 21 installed parallel to both sides, and a first motor 23 located between the double-speed chains 21 on both sides. The double-speed chain 21 is provided with a double-speed chain embedding groove 22, which matches and engages with the horizontal slide rail inside the frame of the frame body 1. The first motor 23 is connected to a horizontal transmission gear sprocket 24, which is connected to a horizontal transmission shaft 25 via a chain. The two ends of the horizontal transmission shaft 25 are respectively connected to the two ends of the double-speed chains 21 on both sides. A membrane 26 is installed on the double-speed chain 21. The workpiece inside the membrane 26 is pressed and fixed by a flip-up pressure fixture. The frame body 1 can hold at least two layers of flip-up pressure fixtures for installing membranes 26. The double-speed chain 21 is provided with a guide block installed on the frame body 1 pointing outward.

The support frame 31 has guide sliders 38 on both sides that match and fit with the guide rail 36. The second motor 35 passes through the first sprocket 310 of the first shaft 39. The first shaft 39 is connected to the second sprocket 312 and the third sprocket 314 at both ends. The second sprocket 312 passes through the second shaft 311, and the third sprocket 314 passes through the third shaft 313.
