Technical Field
[0001] This invention relates to the field of grinding and polishing equipment, and in particular to a grinding and polishing equipment for the outer end face of a metal workpiece. Background Technology
[0002] Steel pipes are widely used in our daily production and life. Before spraying the outer surface of the steel pipe, it is necessary to grind and polish the steel pipe to remove impurities. This not only makes the surface of the steel pipe smoother and shinier, but also enhances its durability and corrosion resistance.
[0003] However, the existing steel pipe grinding equipment still has the following two shortcomings in use: First, when the grinding wheel grinds the steel pipe, one worker needs to put the steel pipe in and another worker needs to take the ground steel pipe out. One grinding process requires two workers. Moreover, the steel pipe is very hot after grinding, which can easily cause burns to the workers who are handling the material. Secondly, steel pipes of different specifications have different dimensions. When workers grind steel pipes of different sizes, they need to adjust the distance between the feed shaft and the guide wheel, which brings inconvenience to the workers' operation. Summary of the Invention
[0004] In view of this, the present invention provides a grinding and polishing device for the outer end face of metal workpieces to solve the problems of the need for another worker to remove the ground steel pipe after the grinding wheel has ground it, the high temperature of the ground steel pipe after grinding, which can easily cause burns to the worker handling the material; and the fact that steel pipes of different specifications have different sizes, and the worker needs to adjust the distance between the feed shaft and the guide wheel when grinding steel pipes of different sizes, which brings inconvenience to the worker's operation.
[0005] The present invention provides a device for grinding and polishing the outer end face of a metal workpiece, which includes: a device box; The device box has a feed hole on the left side plate surface, an inclined guide plate is fixedly installed on the bottom plate surface of the feed hole, a discharge port is opened at the lower position of the rear side plate, a fixed shaft is fixedly installed on the upper end face of the device box, and a first screw is also installed on the upper end face of the device box. The fixing frame has an L-shaped main body and two side baffles at its left and right ends, which are connected to the fixing frame by bolts. The drive motor is fixedly mounted on the outer end face of the left side baffle. The front end of the drive motor is connected to a drive shaft, and the end of the drive shaft is rotatably connected to the right side baffle. The grinding wheel is provided in two sets. The grinding wheel is sleeved on the outside of the drive shaft, and a sleeve is fixedly installed on the outer end face of the grinding wheel. The fixing block is provided in two sets, and the fixing block is fixedly installed on the left side of the lower end face of the device box; The connecting rod is provided in two sets. A rear baffle is fixedly installed on the rear end face of the connecting rod, and the connecting rod is slidably engaged in the through hole on the surface of the fixed block. The top frame has an inclined bottom plate surface and a fixed connection between the front end surface of the top frame and a connecting rod. The guide wheel is located on the top surface of the device box, and a guide frame is fixedly installed on the front end face of the guide wheel; The device box has two sets of fixed plates, which are fixedly installed on the upper end face of the device box. A feed shaft is rotatably connected between the two fixed plates. The collection box has a handle installed at each of its left and right ends, and is located outside the discharge port.
[0006] Furthermore, two transverse track grooves are provided on the inner end face of the top plate of the device box, and an inclined diversion plate is installed on the surface of the bottom plate of the device box.
[0007] Furthermore, a limiting block is fixedly installed at the middle position of the upper end face of the rear baffle, and the limiting block is slidably engaged in the transverse track groove on the inner end surface of the top plate of the device box.
[0008] Furthermore, a compression spring is sleeved on the outside of the connecting rod. The left end of the compression spring is fixedly connected to the fixing block, and the right end of the compression spring is fixedly connected to the rear baffle.
[0009] Furthermore, the bottom plate of the guide wheel has a connecting hole, and the fixed shaft at the top of the device box is engaged in the connecting hole on the surface of the guide wheel.
[0010] Furthermore, the guide frame body has an arc-shaped structure, the first screw is snapped into the inside of the guide frame, and a nut is connected to the surface of the first screw.
[0011] Furthermore, the surface of the drive shaft is provided with a transverse sliding groove, and a fastening block is slidably fitted inside the transverse sliding groove. A fastening screw is fixedly installed on the outer end face of the fastening block.
[0012] Furthermore, the sleeve has a through hole on its surface, and the fastening screw on the outer end face of the fastening block is engaged in the through hole, with a nut connected to the surface of the fastening screw.
[0013] This invention provides a grinding and polishing device for the outer end face of a metal workpiece, which has the following advantages: In this invention, the connecting hole on the surface of the guide wheel base plate is sleeved on the outside of the fixed shaft, and the first screw is snapped into the inside of the guide frame. This allows the worker to loosen the nut on the surface of the first screw and adjust the tilt angle of the guide wheel when grinding steel pipes of different specifications. This adjusts the distance between the guide wheel and the feed shaft, making it easier to grind steel pipes of different sizes.
[0014] Furthermore, when the grinding wheel grinds the steel pipe, the steel pipe pushes the top frame forward. At this time, the connecting rod and the rear baffle also move forward. After the grinding wheel finishes grinding the steel pipe, the steel pipe falls downward, causing the end of the steel pipe to fall onto the surface of the guide plate. Due to the inclined structure of the top frame surface, the steel pipe falls along the guide plate into the device box, and then rolls out from the discharge port on the rear surface of the device box and falls into the collection box. In this way, the worker only needs to put the steel pipe between the guide wheel and the feed shaft, without the need for another worker to catch the steel pipe, saving one laborer and reducing production costs.
[0015] In addition, the grinding wheel and the sleeve are fitted onto the outside of the drive shaft. Workers can increase the number of grinding wheels according to the site conditions. The grinding wheel on the right can grind the steel pipe, and the grinding wheel on the left can polish the steel pipe. The surface of the drive shaft is provided with a transverse sliding groove. A fastening block is slidably fitted inside the transverse sliding groove. The fastening screw at the outer end of the fastening block is engaged in the through hole on the surface of the sleeve. Workers can adjust the position of the grinding wheel on the surface of the drive shaft at will. After adjustment, the nut on the surface of the fastening screw can be tightened to fix the grinding wheel to the outside of the drive shaft.
[0016] In addition, the limiting block at the top of the rear baffle is slidably engaged in the transverse track groove, so that the connecting rod will not wobble left or right when the rear baffle moves back and forth. The guide plate inside the device box has an inclined structure, so that when the round tube falls into the device box, it can be discharged from the discharge port on the rear surface of the device box.
[0017] In addition, a drive motor is installed on the outside of each guide wheel. These drive motors are connected to an external controller, which controls the opening and closing of the drive motor to ensure that the drive motor can drive the guide wheel to rotate synchronously. In this way, when polishing the steel pipe, the drive motor can be started to provide power for the steel pipe to move forward because the contact pressure between the polishing wheel and the steel pipe is small.

[0027] The technical effect achieved by adopting the above solution is as follows: When grinding the outside of the steel pipe, the steel pipe can be placed between the guide wheel 10 and the feed shaft 1201. Different specifications of steel pipes have different sizes. When grinding steel pipes of different sizes, the nut on the surface of the first screw 102 can be loosened, and then the tilt angle of the guide wheel 10 can be adjusted, thereby increasing the distance between the guide wheel 10 and the feed shaft 1201, which facilitates the grinding of steel pipes of different sizes.

[0029] The technical effect achieved by adopting the above solution is as follows: the grinding wheel 4 and the sleeve 401 are sleeved on the outside of the drive shaft 301. The worker can increase the number of grinding wheels 4 according to the site conditions. The grinding wheel 4 on the right side can grind the steel pipe, and the grinding wheel 4 on the left side can polish the steel pipe. The surface of the drive shaft 301 is provided with a transverse sliding groove 3011. The transverse sliding groove 3011 is fitted with a fastening block 5. The fastening screw 501 at the outer end of the fastening block 5 is engaged in the through hole 4011 on the surface of the sleeve 401.

[0030] Example 3: This invention provides a grinding and polishing device for the outer end face of a metal workpiece, based on Example 1, such as... Figures 1-9 As shown, it also includes: a limiting block 7011 is fixedly installed at the middle position of the upper end face of the rear baffle 701, the limiting block 7011 is slidably locked in the transverse track groove 106 on the inner end surface of the top plate of the device box 1, a compression spring 8 is sleeved on the outside of the connecting rod 7, the left end of the compression spring 8 is fixedly connected to the fixing block 6, and the right end of the compression spring 8 is fixedly connected to the rear baffle 701.
[0031] The technical effect of adopting the above solution is as follows: When the grinding wheel 4 grinds the steel pipe, the steel pipe will move forward. When the front end of the steel pipe touches the top frame 9, the steel pipe will push the top frame 9 forward. At this time, the connecting rod 7 and the rear baffle 701 will also move forward. After the grinding wheel 4 finishes grinding the steel pipe, the steel pipe will fall downward, so that the end of the steel pipe will fall downward onto the surface of the guide plate 103. Due to the inclined structure of the surface of the top frame 9, the steel pipe will fall along the guide plate 103 into the device box 1, and then roll out from the discharge port 104 on the rear surface of the device box 1, and then fall into the collection box 13. In this way, the worker only needs to put the steel pipe between the guide wheel 10 and the feed shaft 1201, without the need for another worker to catch the steel pipe, saving one laborer and reducing production costs.
[0032] Example 4: This invention provides a device for grinding and polishing the outer end face of a metal workpiece, such as... Figures 10-11 As shown in Embodiment 1, the guide wheel 10 is fixedly installed above the top plate surface of the device box 1. The guide wheel 10 itself has no power device.

[0033] The specific usage and function of this embodiment: In this invention, when grinding the exterior of a steel pipe, the steel pipe can be placed between the guide wheel 10 and the feed shaft 1201. Different specifications of steel pipes have different sizes. When grinding steel pipes of different sizes, the nut on the surface of the first screw 102 can be loosened, and then the tilt angle of the guide wheel 10 can be adjusted to increase the distance between the guide wheel 10 and the feed shaft 1201, facilitating the grinding of steel pipes of different sizes. When the grinding wheel 4 grinds the steel pipe, the steel pipe will move forward. When the front of the steel pipe... When the end of the steel pipe touches the top frame 9, it pushes the top frame 9 forward. At the same time, the connecting rod 7 and the rear baffle 701 also move forward. After the grinding wheel 4 finishes grinding the steel pipe, the steel pipe will fall downwards, causing the end of the steel pipe to fall onto the surface of the guide plate 103. Due to the inclined structure of the top frame 9, the steel pipe will fall along the guide plate 103 into the device box 1, and then roll out from the discharge port 104 on the rear surface of the device box 1, and then fall into the collection box 13. In this way, the worker only needs to put the steel pipe into the guide wheel 10 and the feed shaft 1201. In this process, no additional worker is needed to handle the steel pipe, saving labor and reducing production costs. The grinding wheel 4 and the sleeve 401 are fitted onto the outside of the drive shaft 301. The worker can increase the number of grinding wheels 4 according to the site conditions. The grinding wheel 4 on the right side can grind the steel pipe, and the grinding wheel 4 on the left side can polish the steel pipe.
