Description

An electric vehicle power steering system production apparatus Technical Field

[0001] This utility model relates to the field of steering gear manufacturing technology, and in particular to a power steering gear manufacturing device for electric vehicles. Background Technology

[0002] The main function of power steering in electric vehicles is to assist drivers in controlling the steering wheel more easily and precisely to steer the vehicle. In traditional mechanical steering systems, drivers need to exert considerable force to turn the steering wheel, especially when the vehicle is traveling at low speeds or turning on the spot, making operation quite strenuous. Electric vehicle power steering, however, can provide additional assistance to the steering system through an electric power-assist mechanism based on information such as vehicle speed, steering wheel angle, and steering speed. This significantly reduces the force required for the driver to turn the steering wheel, making steering easier and more convenient, and reducing driver fatigue.

[0003] In the use of common electric vehicle power steering production equipment, because the steering rod is cylindrical, it is easy for the steering rod to rotate inside the clamping device during the clamping process. During the cutting process of the steering rod, the steering rod will be subjected to force and is more likely to rotate. This brings inconvenience to the surface cutting of the steering rod and reduces the production efficiency of the equipment. Summary of the Invention

[0015] By adopting the above technical solution, a second heating plate is fixed in the third groove opened on the surface of the first arc plate, which can heat the surface of the steering rod to be cut and improve the cutting efficiency.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the first groove is equipped with a telescopic mechanism, which includes a fourth cylinder. The main body of the fourth cylinder is fixedly connected to the inner wall of the first groove. The fourth cylinder is located in front of the third cylinder. The telescopic end of the fourth cylinder is fixedly connected to a first connecting block.

[0018] By adopting the above technical solution, the extension and retraction of the fourth cylinder controls the height of the first connecting block.

[0019] As a further description of the above technical solution:

[0029] 1. Compared with existing technologies, this electric vehicle power steering production device, through a pressure plate, a first cylinder, a cutting blade, and a second cylinder, operates as follows: First, the steering rod to be cut is placed on the surface of a support mechanism. The support mechanism is activated to lift the rod, and then the first cylinder is activated, causing the pressure plate, fixed at the telescopic end of the first cylinder, to contact both ends of the steering rod, initially fixing its position. A first heating plate installed inside the pressure plate heats the surface of the steering rod, facilitating subsequent cutting. Then, the second cylinder is activated, causing the cutting blade, fixed at the telescopic end of the second cylinder, to insert into the steering rod. Because the cutting blade is square, when it cuts through the surface of the steering rod, the blade inserts into the steering rod... Once inside, the steering rod will no longer rotate and will be completely fixed. At this point, activating the cutting mechanism will easily cut the surface of the steering rod. Compared to conventional devices, where the steering rod is cylindrical and easily rotates inside the clamping device during clamping, and is even more prone to rotation under stress during cutting, this device addresses the issue by creating a square groove at the end of the steering rod and inserting a blade into it to prevent rotation during cutting, thus improving production efficiency.

[0030] 2. Compared with the prior art, this electric vehicle power steering production device, through a third cylinder, a fourth cylinder, a second arc plate, and a first arc plate, in use, when the third cylinder is activated, the lifting block fixed at the telescopic end of the third cylinder rises, and the surface of the steering rod is in contact with the surface of the first arc plate. When the fourth cylinder is activated, the third connecting block is rotated upward by the first connecting block, the second rotating shaft, and the second connecting block, which in turn causes the first arc plate and the second arc plate to rotate around the first rotating shaft and close together, which can stably lift the steering rod and move it to a suitable height to be clamped.

The inner wall of the second groove 203 is fixedly... A first heating plate 204 is fixedly connected to the base 101. A first groove 102 is provided on the upper surface of the base 101. A support mechanism 4 is installed on the inner wall of the first groove 102. First, the steering rod to be cut is placed on the surface of the support mechanism 4. The support mechanism 4 is activated to lift it up. Then, the first cylinder 201 is activated so that the pressure plate 202 fixed at the telescopic end of the first cylinder 201 contacts the two ends of the steering rod, initially fixing its position. The first heating plate 204 installed inside the pressure plate 202 heats the surface of the steering rod to facilitate subsequent cutting. Then, the second cylinder 301 is activated so that the cutting blade 302 fixed at the telescopic end of the second cylinder 301 is inserted into the interior of the steering rod. Since the cutting blade 302 is square, after the cutting blade 302 cuts through the surface of the steering rod and inserts into the interior of the steering rod, the steering rod will no longer rotate and will be completely fixed. At this time, the cutting mechanism 6 can be activated to easily cut the surface of the steering rod.

A third connecting block 506 is fixedly connected, with its back side fixedly connected to the outer wall of the first arc-shaped plate 402. When the third cylinder 401 is activated, the lifting block 408 fixed to the telescopic end of the third cylinder 401 rises, and the surface of the steering lever comes into contact with the surface of the first arc-shaped plate 402. When the fourth cylinder 501 is activated, the first connecting block 502, the second rotating shaft 503, and the second connecting block 504 drive the third connecting block 506 to rotate upwards. This causes the first arc-shaped plate 402 and the second arc-shaped plate 403 to rotate around the first rotating shaft 405 and close together, stably supporting the steering lever and moving it to a suitable height where it is clamped. The base 101... A first connecting plate 103 is fixedly connected to the upper surface of the device. A cutting mechanism 6 is installed on the lower surface of the first connecting plate 103.

[0039] Working principle: First, the steering gear rod to be cut is placed on the surface of the support mechanism 4. The support mechanism 4 is activated, lifting the rod and then activating the first cylinder 201. This causes the pressure plate 202, fixed at the telescopic end of the first cylinder 201, to contact both ends of the steering gear rod, initially fixing its position. The first heating plate 204 installed inside the pressure plate 202 heats the surface of the steering gear rod, facilitating subsequent cutting. Then, the second cylinder 301 is activated, causing the cutting blade 302, fixed at the telescopic end of the second cylinder 301, to insert into the interior of the steering gear rod. Because the cutting blade 302 is square, once it cuts through the surface of the steering gear rod and inserts into its interior, the steering gear... The steering rod will no longer rotate and will be completely fixed. At this point, the cutting mechanism 6 can be activated to easily cut the surface of the steering rod. The third cylinder 401 is activated, and the lifting block 408 fixed at the telescopic end of the third cylinder 401 rises. The surface of the steering rod is in contact with the surface of the first arc plate 402. The fourth cylinder 501 is activated, and the first connecting block 502, the second rotating shaft 503, and the second connecting block 504 drive the third connecting block 506 to rotate upward. This causes the first arc plate 402 and the second arc plate 403 to rotate around the first rotating shaft 405 and close together, which can stably lift the steering rod and move it to a suitable height to be clamped.
