Description

Technical Field

[0001] The utility model relates to the technical field of centerless grinders, in particular to a feeding track for shaft parts. Background Art

[0002] During the processing of the centerless grinder, the material to be ground needs to be transported to the grinding wheel and the adjusting wheel of the centerless grinder through the feeding equipment. Usually, a V-shaped groove that can support the material to be ground is provided between the grinding wheel and the adjusting wheel. The existing patent number is CN208467948 U, which is a centerless grinder that can automatically load and unload materials. A V-shaped groove is provided between the grinding wheel and the adjusting wheel of the centerless grinder. The material to be ground is placed in the V-shaped groove. However, the V-shaped groove cannot support the lower end of the material to be ground. During grinding, the material to be ground is prone to fall and get stuck in the V-shaped groove. Moreover, the V-shaped groove is an integrated structure. When different materials to be ground need to be placed, the V-shaped grooves with different angles need to be replaced as a whole. It is inconvenient to adjust the angle of the V-shaped groove. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a feeding track for shaft parts.

[0004] The technical solution of this utility model is as follows:

[0005] A shaft-like parts feeding track is arranged on a centerless grinder, and the centerless grinder has a grinding wheel and an adjusting wheel. The shaft-like parts feeding track includes a workpiece support plate, the length direction of the workpiece support plate is consistent with the axial direction of the grinding wheel, and the workpiece support plate is arranged between the grinding wheel and the adjusting wheel. Inclined plates are symmetrically arranged on both sides of the workpiece support plate along the length direction, the upper end surface of the inclined plate is higher than the upper end surface of the workpiece support plate, and the upper part of the inclined plate is inclined in a direction away from the workpiece support plate. The upper end surface of the workpiece support plate and one side of the two inclined plates close to the workpiece support plate form a channel for feeding shaft-like parts. The workpiece support plate and the inclined plate are both arranged on a base, and the base is arranged on one side of the grinding wheel or the adjusting wheel.

[0006] The inclined plate is detachably connected to the workpiece supporting plate, and the angle between the inclined plate and the workpiece supporting plate is adjustable.

[0007] The two inclined plates are in the same horizontal plane as the workpiece support plate, and the length direction of the inclined plates is consistent with the length direction of the workpiece support plates. The workpiece support plates can support the lower end of the material to be ground to prevent the material to be ground from getting stuck during grinding. The angle between the single inclined plate and the workpiece support plate is adjustable, and shaft parts of different diameters can be placed on the inclined plate and the workpiece support plate; the inclined plate and the workpiece support plate are split structures, and the inclined plate is connected to the workpiece support plate through a connecting piece, and the connecting piece is arranged in the middle of the inclined plate, so that the upper and lower ends of the inclined plate can move toward or away from the side of the workpiece support plate, and there is no need to replace the entire plate during adjustment, thereby achieving the beneficial effect of quickly adjusting the angle between the inclined plate and the workpiece support plate.

[0008] According to the above structure, in order to be able to adjust the angle between the inclined plate and the workpiece support plate, the inclined plate is movably connected to the workpiece support plate through connecting bolts.

[0009] The specific structure of the movable connection between the inclined plate and the workpiece supporting plate is that the inclined plate is provided with a plurality of first through holes, and a connecting bolt is arranged in the first through hole. One end of the connecting bolt passes through the first through hole and is threadedly connected to the workpiece supporting plate, and the bolt head of the connecting bolt cannot pass through the first through hole. The inner diameter of the first through hole is larger than the outer diameter of the connecting bolt, and the connecting bolt can be slidably connected in the first through hole. The lower end surface of the inclined plate is overlapped on the upper end surface of the base, and the first through hole of the inclined plate and the connecting bolt have a certain gap, so that the inclined plate is normally set to be inclined outward, and one end of the connecting bolt passes through the inclined plate and is threadedly connected to the workpiece supporting plate. The outer diameter of the bolt head of the connecting bolt is larger than the inner diameter of the first through hole, and the bolt head can prevent the inclined plate from detaching from the connecting bolt. By tightening or loosening the connecting bolt, the bolt head drives the inclined plate to rotate, and the inclination angle of the inclined plate can also be adjusted. To facilitate the adjustment of the inclination angle of the inclined plate, the first through hole is arranged in the middle and upper part of the inclined plate.

[0010] According to the above structure, the specific structure for adjusting the angle between the inclined plate and the workpiece support plate is that the base is provided with a vertical support plate on the side of the inclined plate away from the workpiece support plate, and one end of a first adjusting bolt is provided to pass through the vertical support plate and contact the inclined plate. The utility model is provided with two inclined plates, therefore, two vertical support plates are provided correspondingly, and the vertical support plate is provided on the upper end surface of the base, and the length direction of the vertical support plate is consistent with the length direction of the workpiece support plate, so that one end of the first adjusting bolt passes through the vertical support plate to the top of the inclined plate; by tightening the first adjusting bolt inwardly, the first One end of the adjusting bolt is pushed to the lower part of the inclined plate, and the lower end of the inclined plate moves toward the direction close to the workpiece support plate. By adjusting the connecting bolt arranged in the middle, the upper end of the inclined plate moves away from the workpiece support plate, and the angle between the inclined plate and the workpiece support plate becomes larger, so that shaft parts with larger diameters can be placed. Similarly, the first adjusting bolt is loosened outward, the connecting bolt is adjusted, and one side of the lower end of the inclined plate is moved to fit tightly with one end of the adjusted first adjusting bolt, so that the lower end of the inclined plate is away from the workpiece support plate, and the upper end of the inclined plate is close to the workpiece support plate, so that shaft parts with smaller diameters can be placed.

[0011] For shaft parts with smaller diameters, it is necessary not only to reduce the angle between the inclined plate and the workpiece support plate, but also to reduce the distance between the upper end surface of the inclined plate and the upper end surface of the workpiece support plate to prevent the outer cylindrical surface of the shaft parts from leaking out of the two inclined plates and affecting grinding. Therefore, it is necessary to adjust the height position of the inclined plate downward. The inclined plate is provided with a plurality of second through holes along the vertical direction. The second through holes are located above the first through holes, and the inner diameter of the second through holes is consistent with that of the first through holes. The height position of the inclined plate can be adjusted by inserting the connecting bolts into the corresponding second through holes.

[0012] In order to facilitate the first adjusting bolt to quickly adjust the inclination angle of the inclined plate, the first adjusting bolt is arranged at the lower part of the inclined plate and below the connecting bolt, so that a smaller force can be used to push the lower end of the inclined plate to move through the first adjusting bolt; if the first adjusting bolt is arranged in a position flush with the connecting bolt, it is not convenient for the first adjusting bolt to push the lower part of the inclined plate to move, and the angle adjustment function of the inclined plate cannot be achieved.

[0013] In order to reduce the occupied area of ​​the first through hole and the second through hole on the inclined plate, the second through hole is arranged directly above the first through hole, and the first through hole and the second through hole are connected. The spacing between the first through hole and the second through hole can also be reduced, so that the inclined plate can be fine-tuned. There are many ways to reduce the spacing between the first through hole and the second through hole. If the adjustment spacing is shortened by reducing the inner diameter of the through hole and the inner diameter of the connecting bolt, the strength of the connecting bolt will be greatly reduced, and the connecting bolt will be prone to deformation.

[0014] The above-mentioned inclined plate and connecting bolt are a sliding connection structure. In order to reduce the shaking of the inclined plate, a nut is provided on the connecting bolt. The nut is located between the inclined plate and the workpiece support plate. The nut is threadedly connected to the connecting bolt, and the outer diameter of the nut is larger than the inner diameter of the first through hole. The nut is pressed against a side of the inclined plate close to the workpiece support plate, but does not affect the inclination angle of the inclined plate, and can also reduce the movement of the inclined plate after adjusting the angle.

[0015] In order to cooperate with the first bolt to adjust the lower end of the inclined plate, a second adjusting bolt is arranged on the vertical support plate. The second adjusting bolt is arranged above the first adjusting bolt, and the second adjusting bolt passes through the vertical support plate to the top of the inclined plate. The second adjusting bolt can cooperate with the first adjusting bolt to adjust the angle of the inclined plate, and can play a supporting role for the inclined plate that is inclined outward.

[0016] According to the above structure, the angle between the inclined plate and the workpiece support plate is set to 20°-90°, which can adapt to the placement of most shaft parts.

[0017] The two inclined plates are arranged in such a position that the centerless grinder has a feeding conveyor belt, the inclined plates are arranged between the discharge port of the feeding conveyor belt and the grinding wheel, the shaft parts are conveyed to one side of the feeding track of the shaft parts through the feeding conveyor belt, and the shaft parts are pushed into the channel formed between the workpiece support plate and the two inclined plates manually or by a robot for grinding.

[0018] The beneficial effects of the utility model are:

[0019] The workpiece support plate is arranged between the grinding wheel and the adjusting wheel, and two inclined plates are arranged on both sides of the workpiece support plate. The upper end surface of the workpiece support plate and the side of the two inclined plates close to the workpiece support plate form a channel for feeding shaft parts. The lower part of the shaft parts is placed on the upper end surface of the workpiece support plate and the side of the two inclined plates. The workpiece support plate can support the lower end of the material to be ground to prevent the material to be ground from getting stuck during grinding. The middle and upper parts of the shaft parts protrude from the outer sides of the two inclined plates to facilitate the grinding of the shaft parts by the grinding wheel, and the angle between the single inclined plate and the workpiece support plate can be adjusted, thereby achieving the effect of quickly adjusting the angle between the two inclined plates, so that shaft materials with different diameters can be placed in the channel for grinding.

[0020] The inclined plate is provided with a plurality of second through holes along the vertical direction. The second through holes are located above the first through holes, and the inner diameter of the second through holes is consistent with that of the first through holes. By inserting the connecting bolts into the corresponding second through holes, the height position of the inclined plate can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1 , Figure 2The centerless grinder has a housing 9, a grinding wheel 10 and an adjusting wheel 11 arranged in the housing 9, the grinding wheel 10 plays a grinding role, and the adjusting wheel 11 plays a role in adjusting the rotation of the material to be ground. The V-shaped groove of the prior art needs to be replaced as a whole when adjusting the angle between the two end faces, which is inconvenient to operate. Therefore, the shaft part feeding track includes a base 1, and a workpiece support plate 2 and an inclined plate 3 are arranged on the base 1. The workpiece support plate 2 is fixedly arranged on the upper end surface of the base 1, and the length direction of the workpiece support plate 2 is consistent with the axial direction of the grinding wheel 10, and is arranged on the grinding wheel 10. Between the grinding wheel 10 and the adjusting wheel 11, inclined plates 3 are symmetrically arranged on both sides of the workpiece support plate 2 along the length direction. The upper end surface of the inclined plate 3 is higher than the upper end surface of the workpiece support plate 2, and the upper part of the inclined plate 3 is inclined in the direction away from the workpiece support plate 2. The upper end surface of the workpiece support plate 2 and the side of the two inclined plates 3 close to the workpiece support plate 2 form a channel for feeding shaft parts; the inclined plate 3 is detachably connected to the workpiece support plate 2, and the angle between the inclined plate 3 and the workpiece support plate 2 is adjustable. The angle between the inclined plate 3 and the workpiece support plate 2 is set to 20°-90°, which can adapt to the placement of most shaft parts. The gap between the grinding wheel 10 and the adjusting wheel 11 is limited. In order to reduce the occupied area of ​​the inclined plate 3 and facilitate the angle adjustment of the inclined plate 3 and the workpiece support plate 2, the inclined plate 3 is arranged on the outside of the grinding wheel 10.

[0031] like Figure 3 , Figure 4 As shown, the two inclined plates 3 are arranged in the position that the centerless grinder has a feeding conveyor belt 12, and the inclined plate 3 is arranged between the discharge port of the feeding conveyor belt 12 and the grinding wheel 10. The shaft parts are conveyed to one side of the feeding track of the shaft parts through the feeding conveyor belt 12, and the shaft parts are pushed between the workpiece support plate 2 and the two inclined plates 3 manually or by a robot. The lower part of the shaft parts is arranged between the workpiece support plate 2 and the two inclined plates 3, and the middle and upper parts of the shaft parts are exposed to the outside of the two inclined plates 3, which is convenient for grinding.

[0032] According to the above structure, the following effects can be achieved: the workpiece support plate 2 located between the grinding wheel 10 and the adjusting wheel 11 is used to support shaft parts, and inclined plates 3 are symmetrically arranged on both sides of the workpiece support plate 2. The inclined plates 3 are inclinedly arranged on the base 1 through connecting pieces, and the two inclined plates 3 are in the same horizontal plane as the workpiece support plate 2. The length direction of the inclined plates 3 is consistent with the length direction of the workpiece support plate 2. The angle between a single inclined plate 3 and the workpiece support plate 2 is adjustable, and shaft parts of different diameters can be placed on the inclined plate 3 and the workpiece support plate 2; the inclined plate 3 and the workpiece support plate 2 are a split structure, and the inclined plate 3 is connected to the workpiece support plate 2 through a connecting piece, and the connecting piece is arranged in the middle of the inclined plate 3, so that the upper end and the lower end of the inclined plate 3 can be moved toward or away from one side of the workpiece support plate 2, and the overall replacement is not required during adjustment, thereby achieving the beneficial effect of quickly adjusting the angle between the inclined plate 3 and the workpiece support plate 2.

[0033] like Figure 5 , Figure 6 As shown, in order to be able to adjust the angle between the inclined plate 3 and the workpiece support plate 2, the inclined plate 3 is movably connected to the workpiece support plate 2 through a connecting bolt 4. Among them, the specific structure of the movably connected inclined plate 3 and the workpiece supporting plate 2 is that the inclined plate 3 is provided with a plurality of first through holes 31 along the length direction, and the plurality of first through holes 31 are on the same horizontal plane. The inner diameter of the first through hole 31 is larger than the outer diameter of the connecting bolt 4, and the connecting bolt 4 can be slidably connected in the first through hole 31. The lower end surface of the inclined plate 3 is mounted on the upper end surface of the base 1. The first through hole 31 of the inclined plate 3 and the connecting bolt 4 have a certain gap, so that the inclined plate 3 is normally set to be inclined outward, and one end of the connecting bolt 4 passes through the inclined plate 3 and is threadedly connected to the workpiece supporting plate 2. The outer diameter of the bolt head 41 of the connecting bolt 4 is larger than the inner diameter of the first through hole 31. The bolt head 41 can prevent the inclined plate 3 from being separated from the connecting bolt 4. By tightening or loosening the connecting bolt 4, the bolt head 41 drives the inclined plate 3 to rotate, and the inclination angle of the inclined plate 3 can also be adjusted. In order to facilitate the adjustment of the inclination angle of the inclined plate 3, the first through hole 31 is set in the middle and upper part of the inclined plate 3. The above-mentioned inclined plate 3 and the connecting bolt 4 are a sliding connection structure. In order to reduce the shaking of the inclined plate 3, at least two nuts 8 are threadedly connected to the connecting bolt 4. The two nuts 8 are arranged on both sides of the inclined plate 3, and the outer diameter of the nut 8 is larger than the inner diameter of the first through hole 31. The two nuts 8 are pressed against the two sides of the inclined plate 3, but do not affect the inclination angle of the inclined plate 3, and can also reduce the movement of the inclined plate 3 after the angle is adjusted.

[0034] The specific structure for adjusting the angle between the inclined plate 3 and the workpiece supporting plate 2 is that the utility model is provided with two inclined plates 3, therefore, two vertical supporting plates 7 are correspondingly provided, and the vertical supporting plate 7 is arranged on the upper end surface of the base 1, and the length direction of the vertical supporting plate 7 is consistent with the length direction of the workpiece supporting plate 2, so that one end of the first adjusting bolt 5 passes through the vertical supporting plate 7 and is pushed to the lower part of the inclined plate 3; by tightening the first adjusting bolt 5 inwardly, one end of the first adjusting bolt 5 is pushed to the lower part of the inclined plate 3, and the lower end of the inclined plate 3 moves in the direction close to the workpiece supporting plate 2, and by adjusting the connecting bolt 4 arranged in the middle, the upper end of the inclined plate 3 moves in the direction away from the workpiece supporting plate 2, and the angle between the inclined plate 3 and the workpiece supporting plate 2 becomes larger, so that shaft parts with larger diameters can be placed; similarly, the first adjusting bolt 5 is loosened outwardly, the connecting bolt 4 is adjusted, and one side of the lower end of the inclined plate 3 is moved to be in close contact with one end of the adjusted first adjusting bolt 5, so that the lower end of the inclined plate 3 is away from the workpiece supporting plate 2, and the upper end of the inclined plate 3 is close to the workpiece supporting plate 2, so that shaft parts with smaller diameters can be placed. If the first adjusting bolt 5 is set flush with the connecting bolt 4, it is not convenient for the first adjusting bolt 5 to push the lower part of the inclined plate 3 to move, and the angle adjustment function of the inclined plate 3 cannot be achieved. In order to facilitate the first adjusting bolt 5 to quickly adjust the inclination angle of the inclined plate 3, the first adjusting bolt 5 is set at the lower part of the inclined plate 3 and below the connecting bolt 4, so that a small force can be used to push the lower end of the inclined plate 3 to move through the first adjusting bolt 5. In order to cooperate with the first bolt to adjust the lower end of the inclined plate 3, a second adjusting bolt 6 is set on the vertical support plate 7. The second adjusting bolt 6 is set above the first adjusting bolt 5, and the second adjusting bolt 6 passes through the vertical support plate 7 and pushes to one side of the inclined plate 3. The second adjusting bolt 6 can cooperate with the first adjusting bolt 5 to adjust the angle of the inclined plate 3, and can play a supporting role for the inclined plate 3 set to be tilted outward.

[0035] For shaft parts with smaller diameters, it is necessary not only to reduce the angle between the inclined plate 3 and the workpiece support plate 2, but also to reduce the distance between the upper end surface of the inclined plate 3 and the upper end surface of the workpiece support plate 2 to prevent the outer cylindrical surface of the shaft parts from leaking out of the two inclined plates 3 and affecting the grinding. Therefore, it is necessary to adjust the height position of the inclined plate 3 downward. The inclined plate 3 is provided with a plurality of second through holes 32 in the vertical direction. The second through holes 32 are located directly above the first through holes 31, and the inner diameter of the second through holes 32 is consistent with that of the first through holes 31. By inserting the connecting bolts 4 into the corresponding second through holes 32, the height position of the inclined plate 3 can be adjusted.

[0036] In order to reduce the occupied area of ​​the first through hole 31 and the second through hole 32 on the inclined plate 3, the second through hole 32 is arranged to be located directly above the first through hole 31, and the first through hole 31 and the second through hole 32 are connected. The spacing between the first through hole 31 and the second through hole 32 can also be reduced, so that the inclined plate 3 can be fine-tuned. There are many ways to reduce the spacing between the first through hole 31 and the second through hole 32. If the adjustment spacing is shortened by reducing the inner diameter of the through hole and the inner diameter of the connecting bolt 4, the strength of the connecting bolt 4 will be greatly reduced, and the connecting bolt 4 will be prone to deformation.

[0037] The material to be ground in the present invention is a shaft part, which generally has a plurality of steps for installation. For the multiple steps, the prior art generally grinds the steps separately. The grinding wheel 10 of the present invention is adapted to the shape of the shaft part, and can realize simultaneous processing of multiple steps of a shaft part, and the concentricity is better than that of individually processing the steps.
