Description

Technical Field

[0001] The present invention relates to the technical field of metal grinding equipment, and specifically relates to a belt type full-automatic end face grinding device. Background Art

[0002] At present, for the processing of connecting rods, a double-end face grinding machine is usually used to grind both sides of the connecting rod. The full-automatic double-end face grinding machine described in CN201872029U includes a machine body, on which a front workbench, a rear workbench, double-sided grinding wheels, a power transmission device, a loading device, a feeding device, an unloading and receiving device, and a control device are provided. Its substantial deficiencies are as follows: First, when the double-end face grinding machine with a chain and opposed roller method grinds thin plate parts, since the parts are thin, it is very easy for the double-sided grinding wheels to collide with each other; Second, since the feeding device of this structure uses a chain for transmission, during the processing, the chain needs to adjust its tension through a tensioning wheel, resulting in a state where the upper part is loose and the lower part is tight, unstable conveying, inaccurate feeding, poor workpiece processing quality, and low work efficiency; Third, when the workpiece to be processed falls onto the chain, due to the unstable center of gravity of the workpiece, it is very easy to fall down, and as a result, the chain is often stuck and unable to operate, with a high failure rate and thus affecting work efficiency. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies of the above-mentioned prior art, and to provide a belt type full-automatic end face grinding device with novel structure, stable operation, high workpiece processing quality, high work efficiency, and very low failure rate.

[0004] The technical solution adopted by the present invention to solve the above technical problems is as follows:

[0004]

[0005] A belt type full-automatic end face grinding device includes a machine body, on which a front workbench, a rear workbench, double-sided grinding wheels, a power transmission device, a loading device, a feeding device, an unloading and receiving device, and a control device are provided. The feeding device includes a conveying belt that can be wound around a shaft and has the ability to carry and convey metal workpieces for grinding and avoid deflection deformation during the conveying process, a front conveying belt reel device, and a rear conveying belt reel device.

[0006] The front conveyor belt reel device includes a front roller frame, a front drive shaft, a front reduction motor, a front reel, and a front conveyor belt protective cover. The front roller frame is composed of a front base, a front support frame, and a front crossbeam. One side of the upper end of the front base is fixedly connected to the front crossbeam through the front support frame, and the lower end is fixedly connected to the front workbench. The front conveyor belt protective cover is fixed to the lower end of the front crossbeam. A front conveyor belt perforation is provided on the side wall of the front conveyor belt protective cover. A front reel is arranged inside the front conveyor belt protective cover. The front reel is fixed on the front drive shaft. The upper end of the front drive shaft is fixedly connected to the front crossbeam through a bearing, and the lower end passes through a lower bearing in a through hole provided on the front base and is connected to the output shaft of the front reduction motor. The front reduction motor is fixed on the front workbench and is driven by a control device.

[0007] The rear conveyor belt reel device includes a rear roller frame, a rear drive shaft, a rear reduction motor, a rear reel, and a rear conveyor belt protective cover. The rear roller frame is composed of a rear base, a rear support frame, and a rear crossbeam. One side of the upper end of the rear base is fixedly connected to the rear crossbeam through the rear support frame, and the lower end is fixedly connected to the rear workbench. The rear conveyor belt protective cover is fixed to the lower end of the rear crossbeam. A rear conveyor belt perforation is provided on the side wall of the rear conveyor belt protective cover. A rear reel is arranged inside the rear conveyor belt protective cover. The rear reel is fixed on the rear drive shaft. The upper end of the rear drive shaft is fixedly connected to the rear crossbeam through a bearing, and the lower end passes through a lower bearing in a through hole provided on the rear base and is connected to the output shaft of the rear reduction motor. The rear reduction motor is fixed on the rear workbench and is driven by a control device.

[0008] The conveyor belt passes through the center of the double-sided grinding wheel. One end passes through the front conveyor belt perforation and is wound around the front reel, and the other end passes through the rear conveyor belt perforation and is wound around the rear reel. Material seat holes are evenly distributed on the circumferential surface of the conveyor belt, which is conducive to driving the materials in the material seat holes into the double-sided grinding wheel for double-sided grinding through the linear movement of the conveyor belt. Due to the large flexural strength of the vertical steel plate, the workpieces on the conveyor belt achieve the effects of stable conveying and accurate feeding, solving the substantial deficiencies that when using a chain, it is necessary to adjust its tension through a tensioning wheel, and there is often a state of loose upper and tight lower, resulting in unstable conveying, inaccurate feeding, high failure rate, poor workpiece processing quality, and low work efficiency.

[0009] The discharge and receiving device of the present invention includes a receiving trough 78 and a discharge pushing device 97. The receiving trough 78 is located on the rear workbench on one side of the conveyor belt. The lower end of the receiving trough 78 is fixedly connected to the rear workbench 3, which is conducive to receiving the processed workpieces on the conveyor belt and achieving the function of automatic material receiving. The discharge pushing device 97 corresponds to the material receiving port of the receiving trough.

[0010] The discharging and pushing device 97 of the present invention further includes a pushing base 79, a material blocking plate 80 and a pushing cylinder 81. The pushing cylinder 81 is controlled by a control device. The pushing cylinder 81 is fixed on the pushing base 79 through the material blocking plate 80. The end of the telescopic rod of the pushing cylinder 81 is fixedly connected to the pushing plate 80. The pushing plate 80 corresponds to the material receiving port of the material receiving groove 78. When the conveying belt carries the ground workpieces and moves between the material receiving groove and the discharging and material receiving device, the workpiece in-place sensor provided on the material receiving groove uploads the information to the control device. The control device then instructs the pushing cylinder to act, and the processed workpieces on the conveying belt are pushed into the material receiving groove through the material blocking plate cylinder 81, achieving the function of automatically controlling pushing and discharging.

[0011] The present invention may be provided with an automatic feeding device above the feeding device of the front workbench on one side of the conveying belt, and a backing plate is provided on the other side. The backing plate is fixedly connected to the front workbench. The automatic feeding device includes a lower bracket, a rotary cylinder bottom plate, a rotary swing cylinder, a feeding cylinder bracket I, a feeding cylinder bracket II, a feeding cylinder I, a feeding cylinder II, a suction cup bracket I, a suction cup bracket II, a vacuum suction cup I and a vacuum suction cup II. The rotary cylinder bottom plate is located above the conveyor belt of the feeding device. The two sides of the lower end of the rotary cylinder bottom plate are respectively cross-fixedly connected to the lower bracket. A rotary swing cylinder is fixed on the rotary cylinder bottom plate. The lower end of the lower bracket is fixedly connected to the front workbench. The ends of the rotary swing cylinder are provided with a feeding cylinder bracket I and a feeding cylinder bracket II. After the feeding cylinder bracket I and the feeding cylinder bracket II are vertically fixedly connected, they are fixedly connected to the rotary swing cylinder. The feeding cylinder I is fixed on the feeding cylinder bracket I. The front end of the telescopic rod of the feeding cylinder I is fixedly provided with a suction cup bracket I. A vacuum suction cup I is fixed on the suction cup bracket I. The feeding cylinder II is fixed on the feeding cylinder bracket II. The front end of the telescopic rod of the feeding cylinder II is fixedly provided with a suction cup bracket II. A vacuum suction cup II is fixed on the suction cup bracket II. The rotary swing cylinder, the feeding cylinder I, the feeding cylinder II, the vacuum suction cup I and the vacuum suction cup II are respectively controlled by a control device. When feeding is required, the control device commands the rotary swing cylinder to rotate, so that the vacuum suction cup I rotates above the conveyor belt and aligns with the workpiece to be adsorbed. When the feeding position sensor on the feeding rack senses the workpiece in place information, the control device immediately commands the feeding cylinder I to act, drives the vacuum suction cup I to contact the workpiece and adsorb the workpiece. Then, the feeding cylinder I retracts and the rotary swing cylinder rotates 180 degrees. At this time, the feeding cylinder I extends, so that the vacuum suction cup carries the workpiece and sends the workpiece into the material seat hole on the conveying belt. The workpiece sits in the material seat hole under the action of the vacuum suction cup I and the backing plate. At this time, the control device commands the front deceleration motor and the rear deceleration motor to act, drives the conveying belt to carry the workpiece in the material seat hole into the double-sided grinding wheel for double-end surface grinding. When the vacuum suction cup I rotates to one side of the steel belt, the vacuum suction cup II aligns with the conveyor belt of the feeding device. The vacuum suction cup II repeats all the actions of the vacuum suction cup I in the same way. In this way, the automatic feeding of the workpiece is completed. During the process of the conveying belt conveying the workpiece, the conveying belt is immediately wound up by the rear conveying belt reel device. When the conveying belt carries the workpiece and is completely released by the front conveying belt reel device and wound into the rear conveying belt reel device, the control device stops feeding, drives the front conveying belt reel device to rotate reversely, winds the conveying belt into the front conveying belt reel device, and then repeats the above actions again.

The structures and connection relationships of the bed body, the feeding device 6, the front workbench 2, the rear workbench 3, the double-sided grinding wheel 4, and the power transmission device 5 are the same as those in the prior art and will not be elaborated here. The feeding device includes a conveying belt 8 that can be wound around a shaft and is capable of carrying and conveying metal workpieces for grinding and avoiding deflection deformation during the conveying process, a front conveying belt reel device 9, and a rear conveying belt reel device 10.

[0046] The front conveying belt reel device 9 includes a front roller frame 11, a front drive shaft 12, a front reduction motor 13, a front reel 14, and a front conveying belt protective cover 15.

[0066] The present invention takes a conveyor belt made of metal steel as an example: during use, the control device is started, and the operator places the workpiece on the conveyor belt. The side loading position sensor senses the workpiece and transmits a signal to the control device. The control device sends a signal to the loading cylinder, and the loading cylinder drives the rack and gear to act. Under the action of the gear and ratchet, the driving roller drives the flat belt to perform a stepping motion, feeding intermittently and smoothly. At the same time, the control device commands the rotary swing cylinder 32 to rotate, so that the vacuum chuck I 39 rotates above the conveyor belt to align with the workpiece to be adsorbed. When the loading position sensor on the loading rack senses the workpiece in place information, the control device commands the feeding cylinder I 35 to act, drives the vacuum chuck I 39 to contact the workpiece, and after adsorbing the workpiece, the feeding cylinder I 35 retracts and the rotary swing cylinder 32 rotates 180 degrees. The adsorption surface of the vacuum chuck I 39 is perpendicular to the horizontal plane and opposite to the conveyor belt. The control device commands the feeding cylinder I 35 to extend, so that the vacuum chuck takes the workpiece and sends the workpiece into the material seat hole on the conveyor belt. The workpiece sits in the material seat hole under the action of the vacuum chuck I 39 and the backing plate 29. The control device commands the front reduction motor 13 and the rear reduction motor 21 to act, driving the conveyor belt 8 to carry the workpiece in the material seat hole into the double-sided grinding wheel 4 for double-end grinding; when the vacuum chuck I 39 rotates to one side of the steel belt, since the end extension lines of the vacuum chuck I 39 and the vacuum chuck II 40 are perpendicular to each other, the vacuum chuck II 40 aligns with the conveyor belt of the loading device and starts to repeat all the actions of the vacuum chuck I 39. In this way, the automatic feeding of the workpiece is completed. During the process of the conveyor belt 8 transporting the workpiece, the conveyor belt 8 is immediately wound up by the rear conveyor belt reel device 10. When the conveyor belt 8 has released all the workpieces carried by the front conveyor belt reel device 9, the control device stops feeding, drives the front conveyor belt reel device 9 to rotate reversely, winds the conveyor belt into the front conveyor belt reel device 9, and then repeats the above actions again;

[0067] When the conveyor belt carries the ground workpiece and moves between the receiving trough and the discharging and receiving device, the workpiece in place sensor provided on the receiving trough uploads the information to the control device. The control device commands the pushing cylinder to act, and through the baffle plate, the processed workpiece on the conveyor belt is pushed into the receiving trough, achieving the function of automatically controlling the pushing and discharging. During the process of the conveyor belt carrying the workpiece and moving, the upper surface of the conveyor belt is clamped by two upper guide rollers 57, and the lower surface of the conveyor belt is clamped by two lower guide rollers and moved forward, ensuring the flatness of the conveyor belt during movement.

[0068] When processing workpieces with different thicknesses, rotate the adjusting handle to drive the adjustment to rotate. The adjusting rod drives the slide rod shaft to move axially along the keyway, thereby adjusting the distance between the backing plate or the guiding auxiliary plate and the conveyor belt.

[0069] When adjusting the perpendicularity of the conveying belt, the position of the upper guiding roller can be adjusted by the upper adjusting screw rod, and the positions of the two lower guiding rollers 57 can be adjusted by the lower adjusting screw rod 74.

[0070] When the position of the conveying belt needs to be adjusted as a whole, the left slide plate 48 can be driven to slide horizontally along the slide rail by rotating the adjusting screw rod, so as to adjust the positions of the upper guiding roller assembly, the lower guiding roller assembly and the main material guiding plate.

[0071] When the workpiece is conveyed unidirectionally for grinding, the control device controls the rotation speed of the rear conveying belt reel device 10 of the coiled conveying belt to be greater than that of the front conveying belt reel device 9, so that the conveying belt is always in a tensioned state, ensuring the stable operation of the conveying belt.

[0072] When the workpiece needs to be finely ground in the present invention, the control device can command the front conveying belt reel device 9 and the rear conveying belt reel device 10 to alternately release and wind the conveying belt, so that the workpiece on the conveying belt reciprocates in the double-sided grinding wheel for grinding. After the grinding reaches the set time, the control device then commands the front conveying belt reel device to release the belt and the rear conveying belt reel device to wind the conveying belt to take out the ground workpiece.

[0073] Due to the adoption of the above structure, the present invention has the advantages of novel structure, stable operation, high workpiece processing quality, high working efficiency and very low failure rate.
