[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model proposes a feeding mechanism for cutting and processing automobile parts. The spring generates a downward thrust on the slider.

[0019] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1-Figure 3 The utility model provides a technical solution: a feeding mechanism for cutting and processing automobile parts, comprising: a bracket 1, a belt 4 is provided on the surface of the bracket 1, a cutting device 2 is provided at one end of the bracket 1, and one end of the raw material 3 is provided on the top of the belt 4, which is characterized in that: a pressure wheel mounting bracket 6 is fixed to the top of the bracket 1, a slider groove 7 is opened on the surface of the pressure wheel mounting bracket 6, a slider 8 is slidably connected in the slider groove 7, a spring 13 is fixed between the top of the slider 8 and the inner wall of the slider groove 7, a pressure wheel shaft 9 is rotatably connected to the surface of the slider 8, and a pressure wheel 16 is sleeved and fixed on the axis body of the pressure wheel shaft 9, and the pressure wheel mounting bracket 6 is provided with several groups, and the several groups of pressure wheel mounting brackets 6 are divided into two rows, and the two rows of pressure wheel mounting brackets 6 are symmetrically distributed about the belt 4, and each row of pressure wheel mounting brackets 6 are distributed in a linear array at the top of the bracket 1, and the bottom end of the pressure wheel 16 is against the top surface of the raw material 3.

[0021] In actual use, the feeding mechanism for cutting and processing automobile parts is as follows: first, the slider 8 moves upward in the slider groove 7 opened on the surface of the pressure wheel mounting frame 6, thereby driving the pressure wheel shaft 9 and the pressure wheel 16 to move upward. At the same time, the movement of the slider 8 causes the spring 13 to be compressed. Then, one end of the raw material 3 is placed on the top surface of the belt 4 and the end of the raw material 3 placed on the belt 4 is placed against the feed port of the cutting device 2. Then, the slider 8 is slowly released, so that the slider 8 moves downward and drives the pressure wheel 16 to move downward through the pressure wheel shaft 9 until the bottom end of the pressure wheel 16 is pressed against the top surface of the raw material 3. At this time, the spring 13 is still in compression. The spring 13 exerts a downward thrust on the slider 8, which is transmitted to the pinch wheel 16 through the pinch wheel shaft 9, causing the pinch wheel 16 to exert a pressing force on the raw material 3. This pressing force can prevent the end of the raw material 3 placed on the belt 4 from tilting, thereby making the length of the raw material 3 greater than the length of the bracket 1. When the belt 4 is running, the friction between the belt 4, the pinch wheel 16 and the raw material 3 can pull the part of the raw material 3 not placed on the belt 4 to the top of the belt 4, which lengthens the time interval for switching the raw materials by the feeding mechanism, thereby improving the efficiency of the cutting process of automotive parts.

[0022] Example 2: On the basis of Example 1, in order to make the pressure wheel shaft 9 maintain a horizontal posture and move upward, a pull rod 12 is fixed to the top of the slider 8, and the top of the pull rod 12 is movably inserted into the surface of the pressure wheel mounting frame 6. The pull rod 12 has a circular rod structure, and the tops of the two groups of pull rods 12 inserted into the surface of the two symmetrical groups of pressure wheel mounting frames 6 are fixed with the same group of connecting plates 14. The connecting plates 14 have a rectangular plate structure, and the tops of the connecting plates 14 are fixed with a handle 15.

[0023] When the clamping wheel axle 9 needs to maintain a horizontal posture and move upward, it is only necessary to pull the handle 15 at the top of the clamping wheel axle 9 upward by hand. The handle 15 drives the connecting plate 14 to move upward. The handle 15 drives the two groups of pull rods 12 at both ends of the clamping wheel axle 9 to move upward synchronously. The two groups of pull rods 12 drive the two groups of sliders 8 to move upward synchronously, thereby achieving the purpose of keeping the clamping wheel axle 9 in a horizontal posture and moving upward.

[0024] Example 3: On the basis of Example 2, in order to enable the slider 8 to move only up and down, slide rails 10 are provided on the two symmetrical inner walls of the slider groove 7, and guide rods 11 are fixed on the two symmetrical end faces of the slider 8. The guide rods 11 are rectangular rod structures, and the two groups of guide rods 11 are respectively slidably connected to the two groups of slide rails 10.

[0025] A guide rod 11 is fixed on the surface of the slider 8, and a slide rail 10 is provided on the inner wall of the slider groove 7. The guide rod 11 is slidably connected to the slide rail 10. The slide rail 10 guides the guide rod 11 so that the guide rod 11 can only move up and down, thereby making the slider 8 only move up and down.

[0026] Example 4: Based on Example 3, in order to prevent the raw material 3 from deviating when moving onto the belt 4, two sets of guide plates 5 are fixed to the top of the bracket 1 away from the cutting device 2, and the two sets of guide plates 5 are symmetrically distributed about the raw material 3.

[0027] Two sets of guide plates 5 are provided on the side of the top of the bracket 1 away from the cutting device 2. When the raw material 3 that is not above the belt 4 moves above the belt 4, the two sets of guide plates 5 are against both sides of the raw material 3 to guide the raw material 3 and prevent the raw material 3 from running off.

[0028] In actual use, the feeding mechanism for cutting and processing automobile parts is as follows: first, the slider 8 moves upward in the slider groove 7 opened on the surface of the pressure wheel mounting frame 6, thereby driving the pressure wheel shaft 9 and the pressure wheel 16 to move upward. At the same time, the movement of the slider 8 causes the spring 13 to be compressed. Then, one end of the raw material 3 is placed on the top surface of the belt 4 and the end of the raw material 3 placed on the belt 4 is placed against the feed port of the cutting device 2. Then, the slider 8 is slowly released, so that the slider 8 moves downward and drives the pressure wheel 16 downward through the pressure wheel shaft 9 until the pressure wheel The bottom end of 16 is pressed against the top surface of the raw material 3. At this time, the spring 13 is still in a compressed state. Therefore, the spring 13 generates a downward thrust on the slider 8. After this thrust is transmitted to the pinch wheel 16 through the pinch wheel shaft 9, the pinch wheel 16 generates a pressing force on the raw material 3. This pressing force can prevent the end of the raw material 3 placed on the belt 4 from tilting, so that the length of the raw material 3 can be greater than the length of the bracket 1. When the belt 4 is running, the friction between the belt 4, the pinch wheel 16 and the raw material 3 can The part placed on the belt 4 is pulled to the top of the belt 4, which lengthens the time interval for switching raw materials of the feeding mechanism and improves the efficiency of cutting and processing of automobile parts. When the clamping wheel shaft 9 needs to maintain a horizontal posture and move upward, it is only necessary to pull the handle 15 at the top of the clamping wheel shaft 9 by hand. The handle 15 drives the connecting plate 14 to move upward, and the handle 15 drives the two groups of pull rods 12 at both ends of the clamping wheel shaft 9 to move upward synchronously. The two groups of pull rods 12 drive the two groups of slide blocks 8 to move upward synchronously, thereby achieving the goal of keeping the clamping wheel shaft 9 in a horizontal posture and moving upward. Purpose of movement: A guide rod 11 is fixed on the surface of the slider 8, and a slide rail 10 is provided on the inner wall of the slider groove 7. The guide rod 11 is slidably connected to the slide rail 10. The slide rail 10 guides the guide rod 11 so that the guide rod 11 can only move up and down, thereby making the slider 8 only move up and down; two sets of guide plates 5 are provided on the side of the top of the bracket 1 away from the cutting device 2. When the raw material 3 that is not above the belt 4 moves above the belt 4, the two sets of guide plates 5 are against both sides of the raw material 3, guiding the raw material 3 and preventing the raw material 3 from running off.
