Description

Technical Field

[0001] The invention relates to the technical field of grinding machines, in particular to a small rubber roller numerical control grinding machine with automatic feeding. Background Art

[0002] In the process of producing small rubber rollers, they need to be processed, such as grinding. Due to the small size of small rubber rollers, if they rely on manual loading, grinding and unloading, the efficiency is low, so a special grinding machine is needed.

[0003] However, the current grinding machines have the following problems: (1) The loading, grinding and unloading processes have a low degree of integration and automation, resulting in low grinding efficiency; (2) The rubber roller is transported to the processing channel through a vibrating plate, and then the rubber rollers on the processing channel are grabbed one by one by the clamp. During the grabbing process, the clamp may grab empty space or grab multiple rollers at a time, which is inconvenient for subsequent processing; (3) After the rubber roller is ground, the clamp needs to be moved by a displacement mechanism, or the rotation mechanism needs to drive the clamp to rotate and move away from the grinding area so that the rubber roller can be placed in the collection area. There is an interval time during the movement or rotation process, which increases the number of steps and reduces the efficiency of unloading. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a small-sized rubber roller numerically controlled grinding machine with automatic feeding to solve the problems mentioned in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] The above technical solution can catch the rubber roller rolling down from the feeding channel through the carrying plate and send it to the clamping mechanism.

[0009] Preferably, the unloading mechanism includes a second cylinder installed on the support frame, a first mounting plate connected to the telescopic end of the second cylinder, a third cylinder connected to the first mounting plate, a second mounting plate connected to the telescopic end of the third cylinder, a finger cylinder connected to the second mounting plate, a hopper connected to the support frame, and an air jet connected to the support frame, the finger cylinder is located between the hopper and the air jet pipe, and the finger cylinder is located on one side of the clamping mechanism; the second cylinder works to drive the finger cylinder close to or away from the clamping mechanism, and the third cylinder works to drive the finger cylinder close to or away from the hopper; the hopper is used to connect to the material box, and the air jet pipe is used to connect to the air compressor, and the air compressor sprays high-pressure gas to blow the rubber roller on the finger cylinder into the hopper.

[0010] According to the above technical solution, after the rubber roller is processed, the rubber roller can be sent to the hopper through the unloading mechanism.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1 A small rubber roller CNC grinding machine with automatic feeding includes a main machine 1, on which an operation panel 2, a support frame 3, a clamping mechanism 4 and a grinding mechanism 5 are provided, on which a loading mechanism 6 and a unloading mechanism 7 are provided, and a vibration plate feeding device 8 is provided on one side of the main machine 1, and an inclined feeding channel 9 is connected to the vibration plate feeding device 8, and the feeding channel 9 is connected to the support frame 4.

[0030] Specifically, Figure 2 , Figure 3As shown, the feeding mechanism 6 includes a first cylinder 601 connected to the support frame, the telescopic end of the first cylinder 601 is connected to a material head body 602, a U-shaped groove is provided on the material head body 602, hinged plates 603 are connected on both sides of the U-shaped groove on the material head body, an L-shaped supporting plate 604 is hinged on the two hinged plates 603, the lower end of the supporting plate 604 is located below the material head body 602, and the lower part of the supporting plate 604 is connected to the lower part of the feeding channel 9, and a notch 605 matching the rubber roller is provided on the bottom surface of the material head body 602 facing the feeding channel. After the rubber roller slides out of the feeding channel 9, it rolls onto the supporting plate 604 and is located in the notch 605. The upper part of the material head body 602 is connected to a limiting rod 606, and a strip hole 607 is provided on the upper part of the supporting plate 604. The limiting rod 606 passes through the strip hole, and the passing end is connected to the limiting plate 608. A spring 609 is sleeved on the limiting rod 606, one end of the spring 609 is connected to the material head body 602, and the other end is connected to the supporting plate 604. A downwardly extending stopper 610 is connected to the support frame 3, and the lower part of the stopper 610 facing the material head body 602 is an inclined surface, and the upper end of the supporting plate 604 rests on the inclined surface, and the supporting plate 604 is squeezed by the inclined surface of the stopper 610, so that the spring 609 is in a compressed state, so that the lower part of the supporting plate 604 is separated from the material head body 602. The rubber roller is sent to the feeding channel 9 by the vibrating disk feeding device 8 and rolls downward from the feeding channel 9. When the first cylinder 601 is in a retracted state, the upper part of the supporting plate 604 contacts the inclined surface of the stopper 610. The lower part of the supporting plate 604 is opened by the squeezing of the stopper 610. The rubber roller falls from the feeding channel 9 onto the supporting plate 604 and enters the notch 605 of the material head body 602. Then the first cylinder 601 extends, driving the material head body 602 to descend, so that the upper part of the supporting plate 604 is separated from the stopper 610. At this time, under the restoring force of the spring 609, the upper part of the supporting plate 604 rotates to the side away from the material head body 602, and the lower part of the supporting plate 604 rotates to the side of the material head body 602, so that the rubber roller is pressed tightly in the notch 605 through the lower part of the supporting plate 604, so as to clamp the rubber roller so as to send the rubber roller to the clamping mechanism 4. It should be noted that after the carrier plate 604 leaves the stopper 610, the upper end of the carrier plate 604 is still below the inclined surface of the stopper 610, so that after the carrier plate 604 rises, the inclined surface of the stopper 610 can squeeze the carrier plate 604, thereby separating the carrier plate 604 from the material head body 602 for the next material connection.

[0031] The clamping mechanism 4 is located below the feeding mechanism 6, and the feeding mechanism 6 receives the rubber roller sent out from the feeding channel 9 and sends it to the clamping mechanism 4.

The tailstock 401 is connected to the main machine 1 through a screw transmission mechanism, the finger cylinder 705 is located on one side between the two ejector pins 406, and the notch 605 on the material head body 602 is located above between the two ejector pins 406. The first cylinder 601 controls the material head body 602 to descend to a set height so that the rubber roller is located between the two ejector pins 406, and then the fourth cylinder 404 works to drive the second rotating shaft 405 to move toward the rubber roller so that the two ejector pins 406 can clamp the rubber roller. Through the operation of the first motor, the first rotating shaft 403 can be driven to rotate, thereby driving the rubber roller to rotate. Through the operation of the screw rotation mechanism, the tail stock 401 can be driven to move, thereby adjusting the position of the tail stock 401.

[0032] The grinding mechanism 5 is connected to the main machine 1 through the X-axis displacement mechanism 10 and the Y-axis displacement mechanism 11, and the grinding mechanism 5 is located on one side of the clamping mechanism 4, and the grinding mechanism 5 grinds the rubber roller on the clamping mechanism 4. Specifically, Figure 2 As shown, the grinding mechanism 5 includes a second motor 501 installed on the Y-axis displacement mechanism, a transmission shaft connected to the second motor through a belt transmission assembly, and a grinding wheel 502 connected to the transmission shaft, and the grinding wheel 502 is located on one side of the clamping mechanism 4. The X-axis displacement mechanism 10 is connected to the main machine 1, and the Y-axis displacement mechanism 11 is connected to the X-axis displacement mechanism 10. The X-axis displacement mechanism 10 and the Y-axis displacement mechanism 11 both use a screw transmission device, which is a prior art and will not be described in detail in this application. After the ejector pin 406 clamps the rubber roller, the grinding mechanism 5 is driven by the X-axis displacement mechanism 10 to align with the rubber roller positioned by the two ejector pins 406, and the grinding mechanism 5 is driven by the Y-axis displacement mechanism 11 to move toward the rubber roller, and then the second motor 501 is started to drive the grinding wheel to rotate through the belt transmission assembly to grind the rubber roller.

When the rubber roller is polished, the second cylinder 701 extends, driving the finger cylinder 705 to move toward the rubber roller, and then the rubber roller on the ejector pin 406 is grabbed by the finger cylinder 705, and then the fourth cylinder 404 contracts to release the ejector pin 406, and then the second cylinder 701 contracts to drive the rubber roller to align with the hopper 706, and then the third cylinder 703 extends to make the rubber roller close to the hopper 706, and then the finger cylinder 705 is released, and the air compressor delivers high-pressure gas to the jet pipe 707, and the rubber roller is blown into the hopper 706 through the strong gas, and the hopper 706 is connected to the collection box (not shown in the figure), so that the rubber roller enters the collection box to realize automatic unloading. In this process, there is no need to drive the finger cylinder to move in a large range, nor to drive the finger cylinder to rotate, which reduces the process, saves time, and improves the efficiency of unloading.
