Description

Technical Field

[0001] This utility model relates to the field of processing housing equipment technology, specifically a fixing device for CNC machining centers. Background Technology

[0002] The car engine is the power source for a vehicle; it's the heart of the car, determining its power, economy, stability, and environmental performance. Based on the power source, car engines can be categorized into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid engines. Common gasoline and diesel engines are reciprocating piston internal combustion engines, converting the chemical energy of fuel into the mechanical energy of piston movement to output power. Gasoline engines have high speeds, low mass, low noise, easy starting, and low manufacturing costs; diesel engines have high compression ratios, high thermal efficiency, and better fuel economy and emissions performance than gasoline engines. The engine casing is an essential component of the car engine. Typically, the engine casing requires CNC machining.

[0003] However, in the existing technology, after the shell is fixed on the CNC machining center, only one side of the shell can be machined. When the other side of the shell needs to be machined, the shell needs to be disassembled and re-fixed, which increases the workload of the staff and is time-consuming and labor-intensive. This needs to be further improved.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a fixing device for CNC machining centers. Utility Model Content

[0005] The purpose of this invention is to provide a fixing device for CNC machining centers to solve the problems mentioned in the background art.

[0019] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0020] like Figures 1-2 As shown, this utility model provides a technical solution for a fixing device for a CNC machining center: it includes a fixing plate 1, which is rectangular in shape. Two U-shaped grooves 4 are symmetrically opened on both sides of the fixing plate 1. The operator places the fixing plate 1 in a pre-set position on the CNC machining center, and then passes four pre-prepared bolts through the four U-shaped grooves 4 to fix the fixing plate 1 to the CNC machining center.

[0021] In this embodiment, a drive assembly is provided on the top surface of the fixed plate 1. The drive assembly includes a reducer 5, which is mounted on the top surface of the fixed plate 1. A servo motor 6 is mounted on the input shaft of the reducer 5, and a connecting assembly is mounted on the output shaft of the reducer 5. When the servo motor 6 is started, the output shaft of the servo motor 6 drives the input shaft of the reducer 5 to rotate, and the input shaft of the reducer 5 drives the connecting assembly to rotate.

[0022] The connecting assembly includes a connecting disc 8, which is elliptical in shape. The connecting disc 8 is mounted on the output shaft of the reducer 5. Two support blocks 9 are symmetrically mounted on the side of the connecting disc away from the reducer 5. A positioning plate 2 is mounted on the top surface of the two support blocks 9. By rotating the connecting disc 8, the connecting disc 8 drives the two support blocks 9 to rotate, and the two support blocks 9 drive the positioning plate 2 to rotate.

[0023] The staff pre-sets the shell to be processed on the positioning plate 2. After one of the top surfaces is processed, the servo motor 6 is started, the positioning plate 2 rotates, and the positioning plate 2 drives the shell to rotate, turning the horizontal shell into a vertical shell, which makes it easier for the CNC machining center to process the side of the shell. The whole rotation process is carried out in an automated manner without the need for staff participation, which reduces the workload of the staff and saves time and effort.

[0024] In this embodiment, a weight-reducing hole 13 is provided on the top surface of the positioning plate 2. The weight-reducing hole 13 reduces the weight of the entire positioning plate 2, thereby reducing the load on the servo motor 6 and saving costs.

[0025] In this embodiment, multiple limiting posts 3 are vertically arranged on the top surface of the positioning plate 2. The shell to be processed is placed on the multiple limiting posts 3. The multiple limiting posts 3 have the function of limiting the shell, reducing the situation where the shell moves spontaneously during processing.

[0026] In this embodiment, a limiting component is provided on the top surface of the positioning plate 2. The limiting component includes four fixing blocks 10, which are respectively installed at the four corners of the positioning plate 2. A cylinder 11 is vertically installed on the top surface of each of the four fixing blocks 10. A limiting rod 12 is installed on the piston of each of the four cylinders 11. The piston rod of the cylinder 11 can move vertically or rotate. After the shell to be processed is placed on the multiple limiting posts 3, the four cylinders 11 are started. The piston rods of the four cylinders 11 drive the limiting posts 3 to rotate to the top of the shell first. Then, the four limiting posts 3 move vertically to the surface of the shell and fix the shell to the positioning plate 2.
