Description

Technical Field

[0001] This utility model relates to a fixing frame, and more particularly to an electromagnet fixing frame for a vibration friction welding equipment. Background Technology

[0002] With the increasing proportion of plastic parts in industries such as automobiles and sanitary ware, some parts that cannot be formed in one step, such as car lights and toilet seats, must undergo secondary welding and fusion to become finished products. Existing vibration friction welding equipment typically uses a hydraulic cylinder for the vibrating platform's electromagnet mounting bracket, requiring the machine head to move back and forth. This is not only complex to operate but also makes it difficult to accurately control the welding depth, thus affecting the product's weld qualification rate. Therefore, the electromagnet mounting brackets of existing vibration friction welding equipment require further improvement. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an electromagnet fixing frame for a vibration friction welding device, which enables the welding head to generate high-frequency reciprocating motion; and ensures that the welding head motion is more precise and reliable, thereby improving the product welding qualification rate.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide an electromagnet fixing frame for a vibration friction welding equipment, including a machine head frame. The machine head frame is provided with a spring connecting plate, a spring, and a machine head. Electromagnets are symmetrically arranged on both sides of the machine head. The spring connecting plate is fixed to the machine head frame with screws. One end of the spring is fixed to the spring connecting plate with screws, and the other end of the spring is fixed to the machine head. The electromagnets are installed on the machine head frame. A gap is reserved between the machine head and the left and right sides of the machine head frame. A silicon steel sheet is provided inside the machine head as an attraction element for the electromagnets. The machine head generates reciprocating motion by attracting and releasing the electromagnets at a high frequency of switching on and off.

[0005] Furthermore, the gap between the machine head and the left and right sides of the machine head frame is 2mm.

[0006] Furthermore, the machine head frame is integrally cast.

[0007] Furthermore, the silicon steel sheet is embedded inside the machine head.

[0008] Compared with the prior art, the present invention has the following advantages: The electromagnet fixing frame of the vibration friction welding equipment provided by the present invention rationally distributes and installs the electromagnet, the machine head, and the spring. The machine head is attracted and released by switching the electromagnets at both ends of the machine head frame on and off. The high elasticity of the spring is used to generate high-frequency reciprocating motion of the machine head; and ensures that the movement of the machine head is more precise and reliable, thereby improving the product welding qualification rate.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Please see Figure 1 , Figure 2 and Figure 3 The electromagnet mounting bracket for the vibration friction welding equipment provided by this utility model includes a machine head frame 1. The machine head frame 1 is provided with a spring connecting plate 4, a spring 5, and a machine head 6. Electromagnets 2 are symmetrically arranged on both sides of the machine head 6. The spring connecting plate 4 is fixed to the machine head frame 1 with screws. One end of the spring 5 is fixed to the spring connecting plate 4 with screws, and the other end of the spring 5 is fixed to the machine head 1. The electromagnets 2 are installed on the machine head frame 1. The machine head 6 and the machine head frame 1 have reserved gaps on the left and right sides. A silicon steel sheet 3 is provided inside the machine head 6 as an adsorption element for the electromagnets 1. The machine head 6 generates reciprocating motion by attracting and releasing the electromagnets 1 at a high frequency.

[0016] The electromagnet mounting bracket provided by this utility model has an electromagnet 2 first fixed on the machine head frame 1. The spring connecting plate 4 is connected to the machine head frame 1 by screws, and is also connected to the machine head 6 through the lower end face of the spring 5. When the electromagnet 2 frequently attracts and releases the silicon steel sheet 3 on the machine head 6, the elasticity of the spring 5 itself causes the machine head 6 to make a rapid left and right reciprocating motion.

[0017] The electromagnet mounting bracket for the vibration friction welding equipment provided by this utility model features an integrally cast head frame 1, resulting in better strength. This reduces machining errors, unnecessary processing, and saves on processing costs, simplifying the manufacturing process. After assembly, it effectively reduces assembly errors, making the head movement more precise and reliable. Preferably, the gap between the head 6 and the left and right sides of the head frame 1 is 2mm. Silicon steel sheets 3 are embedded within the head 6, reducing installation errors and gaps, thus making the movement more precise and stable.

[0018] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
