[0005] The purpose of this utility model is to provide an automatic feeding mechanism for a CNC cylinder liner machining boring machine, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding mechanism for a CNC cylinder liner machining boring machine, comprising a conveying mechanism and a sliding mechanism. The conveying mechanism includes a conveying frame and a conveyor belt rotatably mounted on the conveying frame. Guide plates are fixedly installed on both sides of the conveying frame, and a feeding channel is formed between the two guide plates. A feeding port is provided on one side of the feeding channel, and a pushing component is provided on the side of the feeding channel away from the feeding port.

[0007] The sliding mechanism includes a cross frame disposed at the feed port and a support seat slidably mounted on the cross frame. One end of the cross frame is fixedly mounted to the conveyor frame. A clamping assembly is disposed on the support seat. A sliding screw is rotatably mounted inside the cross frame. A first motor for driving the sliding screw to rotate is fixedly mounted on one end of the cross frame. The support seat is sleeved on the sliding screw and threadedly connected to the sliding screw.

[0008] In a preferred embodiment, the pushing assembly includes a cylinder fixedly mounted on a conveyor frame and a pushing frame fixedly mounted on the piston end of the cylinder.

[0009] In a preferred embodiment, the clamping assembly includes two V-shaped clamping blocks slidably mounted on a support base.

[0012] In a preferred embodiment, guide grooves are provided on both sides of the cross frame, and the support base is slidably connected to the guide grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This automatic feeding mechanism for CNC cylinder liner machining boring machine, through the setting of conveying mechanism and sliding mechanism, allows the cylinder liner to be placed on the conveyor belt during machining. During the operation of the conveyor belt, the guide plate can transport the cylinder liners one by one into the feeding channel for arrangement. When loading is required, the cylinder can be activated to drive the push frame to move, so that the push frame pushes the cylinder liner at the front of the feeding channel out of the feeding port. The cylinder liner pushed out of the feeding port will fall onto the support seat, and the clamping assembly can be used to clamp the cylinder liner. Then, the first motor is activated to drive the sliding screw to rotate, so that the sliding screw drives the support seat to slide along the crossbeam, moving the cylinder liner under the boring tool for machining. This replaces manual loading by the operator, saves labor and improves work efficiency.

[0015] The automatic feeding mechanism of this CNC cylinder liner machining boring machine, through the setting of the clamping component, can start the second motor to drive the bidirectional screw to rotate when clamping the cylinder liner, so that the bidirectional screw drives the two V-shaped clamping blocks to move closer to each other, thereby clamping the cylinder liner and ensuring the stability of cylinder liner movement and machining.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-3 This utility model provides an automatic feeding mechanism for a CNC cylinder liner machining boring machine, including a conveying mechanism 1 and a sliding mechanism 2. The sliding mechanism 2 is set on the machining table of the boring machine. The conveying mechanism 1 includes a conveying frame 11 and a conveyor belt 12 rotatably mounted on the conveying frame 11. Guide plates 13 are fixedly installed on both sides of the conveying frame 11, and a feeding channel 14 is formed between the two guide plates 13. With the setting of the conveying mechanism 1, the cylinder liner can be placed on the conveyor belt 12 when machining the cylinder liner. During the operation of the conveyor belt 12, the guide plates 13 can transport the cylinder liners one by one into the feeding channel 14 for arrangement.

[0023] Specifically, a feeding port 15 is provided on one side of the feeding channel 14, and a pushing assembly 16 is provided on the side of the feeding channel 14 away from the feeding port 15. The pushing assembly 16 includes a cylinder 161 fixedly installed on the conveyor frame 11 and a push frame 162 fixedly installed on the piston end of the cylinder 161. With the setting of the feeding port 15 and the pushing assembly 16, when feeding is required, the cylinder 161 can be activated to drive the push frame 162 to move, so that the push frame 162 pushes the cylinder liner located at the front of the feeding channel 14 from the feeding port 15 onto the sliding mechanism 2.

[0024] Reference Figure 1 and Figure 2The sliding mechanism 2 includes a crossbeam 21 located at the feed inlet 15 and a support seat 22 slidably mounted on the crossbeam 21. One end of the crossbeam 21 is fixedly mounted to the conveyor frame 11. A clamping assembly 23 is provided on the support seat 22. A sliding screw 24 is rotatably mounted inside the crossbeam 21. A first motor 25 for driving the sliding screw 24 to rotate is fixedly mounted at one end of the crossbeam 21. The support seat 22 is sleeved on the sliding screw 24 and threadedly connected to the sliding screw 24. The two sides of the crossbeam 21... Each part is provided with a guide groove 26, and the support base 22 is slidably connected to the guide groove 26. Through the setting of the sliding mechanism 2, the cylinder liner pushed out from the feed port 15 will fall onto the support base 22. The clamping assembly 23 is used to clamp and fix the cylinder liner. Then, the first motor 25 is started to drive the sliding screw 24 to rotate, so that the sliding screw 24 drives the support base 22 to slide along the cross frame 21, and moves the cylinder liner to the bottom of the boring tool for processing. This replaces the manual feeding by the staff, saves the labor of workers, and improves work efficiency.

[0025] Specifically, the clamping assembly 23 includes two V-shaped clamping blocks 231 slidably mounted on the support base 22. A bidirectional screw 232 is rotatably mounted on one side of the support base 22, and a second motor 233 for driving the bidirectional screw 232 to rotate is fixedly mounted on one end of the support base 22. The two V-shaped clamping blocks 231 are respectively sleeved on both ends of the bidirectional screw 232 and threadedly connected to the bidirectional screw 232. A guide rod 235 is fixedly mounted on the other side of the support base 22, and the V-shaped clamping blocks 231 are slidably sleeved on the guide rod 235. Through the setting of the clamping assembly 23, when clamping the cylinder liner, the second motor 233 can be started to drive the bidirectional screw 232 to rotate, so that the bidirectional screw 232 drives the two V-shaped clamping blocks 231 to move closer to each other, thereby clamping the cylinder liner and ensuring the stability of the cylinder liner movement and processing.

[0026] Among them, an anti-slip pad 234 is fixedly connected to the clamping surface of the V-shaped clamping block 231. The anti-slip pad 234 can improve the friction of the V-shaped clamping block 231 when clamping the cylinder liner, making the clamping more stable.

[0027] The working principle and usage process of this utility model are as follows: First, when processing cylinder liners, the cylinder liners can be placed on the conveyor belt 12. During the operation of the conveyor belt 12, the guide plate 13 can transport the cylinder liners one by one into the feeding channel 14 for arrangement. When feeding is required, the cylinder 161 can be started to drive the push frame 162 to move, so that the push frame 162 pushes the cylinder liner at the front of the feeding channel 14 out of the feeding port 15. The cylinder liner pushed out of the feeding port 15 will fall onto the support seat 22. The second motor 233 can be started to drive the bidirectional screw 232 to rotate, so that the bidirectional screw 232 drives the two V-shaped clamps 231 to move closer to each other, thereby clamping the cylinder liner. Then, the first motor 25 is started to drive the sliding screw 24 to rotate, so that the sliding screw 24 drives the support seat 22 to slide along the crossbeam 21, moving the cylinder liner under the boring tool for processing. This replaces manual feeding by the workers, saves labor, and improves work efficiency.
