Description

Technical Field

[0001] This utility model relates to the field of bus chassis processing technology, specifically to an auxiliary production component for bus chassis processing. Background Technology

[0002] With the continuous advancement of the automotive industry, competition in the automotive market is becoming increasingly fierce. Especially in today's society, where automotive design and manufacturing levels are highly mature, competition is exceptionally intense. Automotive market competition is no longer just about quality and brand, but also about the price-performance ratio of vehicles.

[0003] More than 90% of the materials used in a car are automotive steel. During the steel processing, it is sometimes necessary to center and fix two workpieces or center them for processing to facilitate subsequent operations. Generally, manual alignment has low accuracy, which affects the yield of finished products. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an auxiliary production component for bus chassis processing, which can realize the centering assembly operation or centering processing operation of two components by using two cylinders, which facilitates the processing of subsequent production lines.

[0005] To solve the above-mentioned technical problems, this utility model provides an auxiliary production component for bus chassis processing, including a base. Two symmetrical first mounting profiles are provided on the base, and second mounting profiles are provided on the inner sides of each of the first mounting profiles. A cylinder assembly is provided on each of the first mounting profiles. Slide rails are provided on both sides of each of the second mounting profiles, and a movable plate connected to the cylinder assembly is provided between the slide rails. A rotating base plate is provided between the second mounting profiles, and a rotating shaft is provided on the rotating base plate. A rotating arm is provided on the rotating shaft, and the two sides of the rotating arm are connected to the two movable plates respectively via tie rods.

[0006] Furthermore, centering limit rods are evenly spaced on the movable plate.

[0007] Furthermore, the bottom of the movable plate is provided with a sliding block adapted to the slide rail.

[0008] Furthermore, both the rotating arm and the moving plate are provided with fixed seats, and fisheye bearings adapted to the fixed seats are respectively provided on both sides of the pull rod.

[0009] Furthermore, reinforcing ribs are provided at the connection points between the first mounting profile, the second mounting profile, and the base.

[0010] Furthermore, the rotating shaft is located at the center of the rotating arm.

[0011] The beneficial effects of this utility model are as follows: When using this device, the bottom mold of the workpiece is first fixed by the centering limit rod. The centering limit rod can be of different lengths or the number can be set as needed, as long as it can fix the bottom mold. After fixing, one of the cylinder components is started to drive the moving plate to move along the slide rail. Then the rotating arm connected to this moving plate will rotate along the rotating axis, which will drive the moving plate on the other side to move through the pull rod of the other one. Since the rotating axis is in the center position, the moving distance of the two moving plates is equal. That is, the two moving plates will move inward or outward at the same time to achieve centering operation or separation. Attached Figure Description

[0020] Reference Figure 1 As shown, an embodiment of an auxiliary production component for processing a bus chassis according to this utility model includes a base 1. Two symmetrical first mounting profiles 2 are provided on the base 1. A second mounting profile 3 is provided on the inner side of each of the first mounting profiles 2. A cylinder assembly 4 is provided on the first mounting profile 2. Slide rails 5 are provided on both sides of the second mounting profiles 3. A movable plate 6 connected to the cylinder assembly 4 is provided between the slide rails 5. A rotating base plate 7 is provided between the second mounting profiles 3. A rotating shaft 8 is provided on the rotating base plate 7. A rotating arm 9 is provided on the rotating shaft 8. The two sides of the rotating arm 9 are connected to the two movable plates 6 respectively by tie rods 10. Centering limit rods 11 are evenly spaced on the movable plates 6. The rotating shaft 8 is located at the center of the rotating arm 9.

[0021] In use, the bottom mold for loading the workpiece is first fixed by the centering limit rod 11. The centering limit rod 11 can be of different lengths or the number can be set as needed, as long as it can fix the bottom mold. After fixing, one of the cylinder components 4 is started to drive the moving plate 6 to move along the slide rail 5. Then the rotating arm 9 connected to this moving plate 6 will rotate along the rotating shaft 8, which will drive the moving plate 6 on the other side to move through the pull rod 10 of the other one. Since the rotating shaft 8 is in the center position, the moving distance of the two moving plates 6 is equal. That is, the two moving plates 6 will move inward or outward at the same time to achieve centering operation or separation.

[0022] If one of the cylinder assembly 4 is damaged, the other cylinder assembly 4 can still perform the same operation. If more precise control is required, both cylinder assemblies 4 can be operated simultaneously.

[0023] The bottom of the movable plate 6 is provided with a sliding block 12 that is adapted to the slide rail 5, which reduces the friction between the movable plate 6 and the slide rail 5 and facilitates the movable plate 6 to move back and forth along the slide rail 5.

[0024] Both the rotating arm 9 and the movable plate 6 are provided with fixed seats 13. The pull rod 10 is provided with fish-eye bearings 14 that are adapted to the fixed seats 13 on both sides. The fish-eye bearings 14 can rotate along the fixed point, reducing resistance during the rotation of the rotating arm 9 and facilitating the adjustment of the position of the two movable plates 6.

[0025] The first mounting profile 2, the second mounting profile 3 and the base 1 are provided with reinforcing ribs 15 to enhance the integrated structure.

[0026] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto.
