Description

Technical Field

[0001] This utility model relates to a feeding mechanism for a double-end face grinder. Background Technology

[0002] Double-end grinding machines have two parallel grinding wheels, which can grind both ends of the workpiece simultaneously, thereby reducing the number of processes and auxiliary time and improving grinding efficiency.

[0003] Double-end grinding machines are well-suited for grinding large quantities of cylindrical workpieces from both ends. However, before grinding, it is essential to ensure that each cylindrical workpiece is vertically fed onto the lower grinding wheel of the double-end grinding machine. To achieve this, operators must manually remove the cylindrical workpieces that are scattered in the hopper and place them vertically onto the lower grinding wheel one by one. Therefore, the feeding process for cylindrical workpieces is cumbersome, time-consuming, labor-intensive, and has high labor costs, which requires further improvement. Utility Model Content

[0025] like Figures 1-3As shown, a feeding mechanism for a double-end face grinder includes a frame 1 and a feeding assembly 2 disposed on the frame 1.

[0026] The material distribution assembly 2 includes a first baffle 27 and a second baffle 28 that are vertically fixed to the top of the frame 1 and respectively arranged on the left and right; two fan-shaped clamps 21 that are vertically and movably interspersed on the top of the frame 1 and respectively symmetrically distributed on the left and right between the first baffle 27 and the second baffle 28; a traction cylinder 22 disposed in the frame 1; and a material carrying strip 23 fixed between the two fan-shaped clamps 21.

[0027] The arc edge of each sector clamp 21 is set to face backward so that the two right-angled sides of each sector clamp 21 are distributed vertically. The material carrier strip 23 is fixed between the upper right-angled sides of the two sector clamps 21. The top of the material carrier strip 23 is provided with a V-shaped groove 231 that runs in the front and back direction.

[0028] The two sector-shaped clamps 21 are rotatably connected to the top of the platform 1 at their central corners. The fixed end of the traction cylinder 22 is rotatably connected to the bottom of the platform 1. The telescopic end of the traction cylinder 22 is rotatably connected between the lower right-angled sides of the two sector-shaped clamps 21.

[0029] The material distribution assembly 2 also includes a material blocking unit, which includes a bracket 24 fixed to the front end of the material carrier 23, a material blocking cylinder 25 fixed on the bracket 24 and located above the material carrier 23, and a pressure block 26 fixed on the telescopic end of the material blocking cylinder 25. The telescopic end of the material blocking cylinder 25 is inclined downward toward the V-groove 231.

[0030] The pressure block 26 is arranged parallel to the direction of the V-groove 231. A pusher plate 261 is formed downward on the front edge of the pressure block 26. The angle between the end of the pusher plate 261 and the bottom of the pressure block 26 is an acute angle so that the end of the pusher plate 261 is not perpendicular to the length direction of the V-groove 231.

[0031] The upper edge of the second baffle 28 forms a guide plate 281 facing the upper right. The guide plate 281 is also provided with a discharge assembly 3. The discharge assembly 3 includes two side plates 33 that are vertically fixed to the top of the guide plate 281 and symmetrically arranged front and back, and a sealing plate 31 that is vertically fixed between the top of the guide plate 281 and the right edge of the two side plates 33.

[0032] Each of the two side plates 33 has a symmetrically distributed notch 331 at the upper left corner. The discharge assembly 3 also includes a limiting plate 32 that is vertically fixed between the inner right walls of the two notches 331. The limiting plate 32, the sealing plate 31 and the two side plates 33 form a storage compartment 36.

[0033] The material discharge assembly 3 also includes multiple partition plates 34 that are vertically fixed to the top of the guide plate 281 and are arranged at equal intervals from front to back. A material guide channel 35 is formed between a front side plate 33 and the frontmost partition plate 34, between a rear side plate 33 and the last partition plate 34, and between any two adjacent partition plates 34.

[0034] The top of the guide plate 281 is provided with a plurality of arc-shaped guide grooves 282 arranged at equal intervals from front to back. The number of arc-shaped guide grooves 282 is equal to the number of material guide channels 35, and each arc-shaped guide groove 282 is located in the central area inside a corresponding material guide channel 35.

[0035] Each arc-shaped guide groove 282 has a rectangular screening hole 283 that extends through to the bottom of the guide plate 281 between its inner wall and the top outer wall of the guide plate 281. The front-to-back length of the rectangular screening hole 283 is less than the width of the guide channel 35, and the left-to-right length of the rectangular screening hole 283 is not less than the width of the guide channel 35.

[0036] Multiple inclined receiving grooves 5 are fixed on the bottom outer wall of the guide plate 281 and arranged sequentially from front to back. The number of receiving grooves 5 is equal to the number of rectangular screen holes 283. The root opening of each receiving groove 5 is higher than its end opening and is located below the corresponding rectangular screen hole 283.

[0037] A support frame 4 is also fixed between the bottom of the guide plate 281 and the top of the platform 1.

[0038] Working principle:

[0039] A certain number of cylindrical workpieces 6 are poured into the storage bin 36. The cylindrical workpieces 6 will fall into each guide channel 35 by their own gravity. The setting of the limiting plate 32 ensures that only a single cylindrical workpiece 6 can pass through the lower edge of the limiting plate 32 and move to the left side of the limiting plate 32. At the same time, upright cylindrical workpieces 6 cannot pass through and must be tilted down to pass through.

[0040] The columnar workpieces 6 entering the feed channel 35 have two states. One is that their two ends are distributed front and back, which is the standard state required for feeding. In this state, the columnar workpieces 6 can roll down to the left along the top outer wall of the guide plate 281 with the help of their outer circumference, and then roll into the V-shaped groove 231 at the top of the material carrier 23 and be arranged sequentially from front to back. Since the upper surface of the columnar workpieces 6 in the V-shaped groove 231 is higher than the lower surface of the subsequent columnar workpieces 6 in the feed channel 35, the subsequent columnar workpieces 6 in the feed channel 35 will not continue to roll and stack. Also, since the front and back width of the rectangular screen hole 283 is less than the length of the columnar workpieces 6, the rolling columnar workpieces 6 will not fall down when rolling through the rectangular screen hole 283.

[0041] Another state in which the columnar workpiece 6 enters the material guide channel 35 is that the two ends of the columnar workpiece 6 are distributed with the left end lower than the right end. In this case, the columnar workpiece 6 will move to the lower left along the top outer wall of the guide plate 281, but will gradually enter the arc-shaped guide groove 282 while moving, so that the movement of the columnar workpiece 6 is a straight trajectory and does not move back and forth. When the columnar workpiece 6 moves to the rectangular screen hole 283, the columnar workpiece 6 will fall down from the rectangular screen hole 283 into the receiving groove 5, and then be automatically output outward along the slope of the receiving groove 5 to be collected, so as to be poured back into the storage bin 36 in the subsequent operation.

[0042] Next, the telescopic end of the drive traction cylinder 22 extends outward to drive the two fan-shaped clamps 21 to rotate upward, thereby causing the material carrier 23 to gradually tilt downward and upward with an increasingly larger tilt angle, so that each columnar workpiece 6 on the material carrier 23 moves forward and downward along the V-groove 231 and comes close to each other; while the right outer wall of the right fan-shaped clamp 21 will gradually move upward and be higher than the root edge of the guide plate 281, so that each subsequent columnar workpiece 6 will not continue to move.

[0043] In the initial state, the pusher plate 261 on the pressure block 26 in the stop unit is located in front of the V-groove 231. The foremost columnar workpiece 6 will be blocked by the pusher plate 261 when it moves down and cannot continue to move forward and downward. When the angle between the material bar 23 and the horizontal direction is about to reach 90 degrees, the swing of the material bar 23 stops. At this time, the front end of the material bar 23 is located above the lower grinding wheel of the double-end grinding machine.

[0044] Subsequently, the telescopic end of the baffle cylinder 25 in the drive baffle unit retracts inward to move the pressure block 26 forward and upward. When the pusher plate 261 moves to the front and above the foremost columnar workpiece 6, the foremost columnar workpiece 6 slides down onto the lower grinding wheel of the double-end face grinder and immediately becomes vertical, thus completing the feeding of the columnar workpiece 6. The subsequent columnar workpiece 6 is blocked by the upper end of the aforementioned columnar workpiece 6 and will not fall. However, since the front end of the subsequent columnar workpiece 6 is still inclined, it falls onto the lower grinding wheel of the double-end face grinder. A gap will appear between the upper ends of a columnar workpiece 6 on the lower grinding wheel. Then, the telescopic end of the drive stop cylinder 25 extends outward to drive the pressure block 26 to move backward and upward, thereby causing the end of the pusher plate 261 to insert into the gap and gradually push each columnar workpiece 6 located on the material carrier 23 to move backward and upward along the V-groove 231, so that the front end of the subsequent columnar workpiece 6 separates from the upper end of the columnar workpiece 6 falling onto the lower grinding wheel, until the pressure block 26 presses firmly on the subsequent columnar workpiece 6.

[0045] Finally, the lower grinding wheel of the double-end face grinder is slightly rotated at a certain angle to make room for the next cylindrical workpiece 6 to fall. The telescopic end of the stop cylinder 25 is then driven to retract inward to move the pressure block 26 forward and upward, so that the next cylindrical workpiece 6 slides down onto the lower grinding wheel of the double-end face grinder and immediately becomes vertical. This process is repeated until each cylindrical workpiece 6 on the material carrier 23 is vertically placed onto the lower grinding wheel of the double-end face grinder. Then, the telescopic end of the traction cylinder 22 is driven to retract inward to gradually bring the material carrier 23 to a horizontal position, so that the subsequent cylindrical workpieces 6 fall onto the material carrier 23, thus forming a cycle.

[0046] This invention can automatically orient and arrange multiple cylindrical workpieces 6 that are randomly poured into the storage bin 36 using the discharge component 3, and can automatically feed each cylindrical workpiece 6 vertically to the lower grinding wheel of the double-end face grinder using the distribution component 2. It can also automatically remove cylindrical workpieces 6 whose arrangement direction does not meet the requirements. All of the above processes do not require manual operation, thus greatly simplifying the feeding process of cylindrical workpieces 6 to achieve the effect of saving time and labor, thereby effectively reducing labor intensity and lowering labor costs.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
