TECHNICAL FIELD

[0001] The utility model relates to automatic equipment field, concretely is a lighter grinding wheel assembly unloading structure. BACKGROUND

[0002] As Figure 1 And Figure 2 As shown in the prior art, a common lighter grinding wheel, its structure includes steel wheel 1' and the edge wheel 2' set at both ends of steel wheel 1', steel wheel 1' has axial through hole 11', and the edge wheel 2' has the shaft head 21' towards steel wheel 1' on it.Usually, the assembly mode of lighter grinding wheel is as shown in Figure 2 The edge wheel 2' is placed at both ends of steel wheel 1', and then external force is applied simultaneously from both ends along the axial direction, so that the shaft head 21' of the edge wheel 2' on both sides of steel wheel 1' is fitted into the through hole to form a tight fit.

[0003] The applicant found in practice that, since the lighter grinding wheel is three independent components before assembly, when the unloading mode as shown in Figure 2 Is used for assembly, the axial through hole 11' of steel wheel 1' and the shaft head 21' of the edge wheel 2' at the end are simultaneously impacted, and under the condition that the axial through hole 11' has impact points at both ends, the external force originally applied along the axial direction has a higher probability of deviating from the axial direction in the transmission process, so that the lighter grinding wheel after assembly presents Figure 3 As shown, that is, the edge wheel 2' is skewed relative to the steel wheel 1' and is no longer coaxial.Obviously, once the lighter grinding wheel after assembly presents Figure 3 As shown, it will be difficult to normally assemble in the lighter, and it is also difficult to normally work in the lighter.

[0004] Therefore, in order to improve the coaxiality of the edge wheel 2' and the steel wheel 1' after assembly of the lighter grinding wheel, a new technical scheme for the assembly process of the lighter grinding wheel is urgently needed. UTILITY MODEL CONTENTS

[0006] The lighter grinding wheel assembly feeding mechanism includes an axially horizontal rotating wheel. A coaxial annular groove is formed on the outer circumference of the rotating wheel. The bottom surface of the annular groove has multiple arc-shaped grooves equidistantly distributed around the rotating wheel. The axial direction of the arc-shaped grooves is parallel to the rotating wheel. A stamping port corresponding to each arc-shaped groove is provided on the sidewalls of both sides of the annular groove. The stamping port passes through the sidewalls of both sides of the annular groove along the axis of the corresponding arc-shaped groove. On the side of each arc-shaped groove located in the clockwise direction of the rotating wheel, a first guide groove, a second guide groove, and a third guide groove are provided in parallel along the width direction of the annular groove. The first, second, and third guide grooves gradually rise at their beginnings to transition to the bottom surface of the annular groove, and their ends gradually sink to cut into the arc-shaped grooves.

[0007] It also includes a feeding module located on the upper edge of the rotating wheel. The bottom end of the feeding module is precisely embedded in the annular groove for sliding fit, and the bottom end of the feeding module forms an arc-shaped limiting section that fits with the bottom surface of the annular groove.

When the rotating wheel rotates, the first feeding port is exactly located on the rotation trajectory of the first guide groove, the second feeding port is exactly located on the rotation trajectory of the second guide groove, and the third feeding port is exactly located on the rotation trajectory of the third guide groove. The second feeding port is located on the counterclockwise side of the rotating wheel relative to the first feeding port, and the third feeding port is located on the clockwise side of the rotating wheel relative to the first feeding port.

[0008] Preferably, the clockwise rotation of the rotary wheel causes the arc of a circular groove to move from the second feed outlet to the first feed outlet to be less than the arc of the interval between two adjacent circular grooves.

[0009] Preferably, the clockwise rotation of the rotary wheel causes the arc of a circular groove to move from the first feed outlet to the third feed outlet to a radius greater than the arc of the interval between two adjacent circular grooves.

[0010] Preferably, on the side of the arc-shaped limiting section located in the clockwise direction of the rotating wheel, the bottom end of the feeding module also forms a tangential separation section that is tangential to the arc-shaped limiting section.

[0011] Preferably, the wheel includes a pair of coaxially arranged turntables and a coaxially arranged middle disc sandwiched between the turntables. The diameter of the middle disc is smaller than that of the turntables. The bottom surface of the annular groove is formed by the outer circular surface of the middle disc, and the sidewalls of the annular groove are formed by the rims of the turntables.

[0012] Preferably, the arc-shaped groove has a coaxial arc-shaped rib in the middle of its arc surface, and the arc-shaped rib is exactly centered within the opening range of the tail end of the second guide groove.

[0026] Please see Figures 4 to 11As shown, in one embodiment, the lighter grinding wheel assembly feeding mechanism of this utility model includes an axially horizontal rotating wheel 1. A coaxial annular groove 2 is formed on the outer circular surface of the rotating wheel 1. The bottom surface of the annular groove 2 has a plurality of arc-shaped grooves 21 equidistantly distributed around the rotating wheel 1. The axial direction of the arc-shaped grooves 21 is parallel to the rotating wheel 1. A stamping port 22 corresponding to the arc-shaped groove 21 is provided on the sidewalls of both sides of the annular groove 2. The stamping port 22 passes through the sidewalls of both sides of the annular groove 2 along the axis of the corresponding arc-shaped groove 21. On the side of each arc-shaped groove 21 located in the clockwise direction of the rotating wheel 1, a first guide groove 23, a second guide groove 24, and a third guide groove 25 are provided in parallel along the width direction of the annular groove 2. The first ends of the first guide groove 23, the second guide groove 24, and the third guide groove 25 gradually rise to transition to the bottom surface of the annular groove 2, and the tail ends gradually sink to cut into the arc-shaped groove 21.

[0027] It also includes a feeding module 3 located on the upper edge of the rotating wheel 1. The bottom end of the feeding module 3 is precisely embedded in the annular groove 2 for sliding engagement, and the bottom end of the feeding module 3 forms an arc-shaped limiting section 31 that engages with the bottom surface of the annular groove 2. The bottom surface of the arc-shaped limiting section 31 is also provided with a first feeding port 32, a second feeding port 33, and a third feeding port 34 that extend upward through the feeding module 3. When the rotating wheel 1 rotates, the first feeding port 32 is precisely located on the rotation trajectory of the first guide groove 23, the second feeding port 33 is precisely located on the rotation trajectory of the second guide groove 24, and the third feeding port 34 is precisely located on the rotation trajectory of the third guide groove 25. The second feeding port 33 is located on the counterclockwise side of the rotating wheel 1 relative to the first feeding port 32, and the third feeding port 34 is located on the clockwise side of the rotating wheel 1 relative to the first feeding port 32.

[0028] In the above embodiments, the lighter grinding wheel assembly and feeding mechanism of this utility model improves the working method of one-time feeding and assembly of the steel wheel and the side wheel of the grinding wheel in the prior art. Instead, it feeds and distributes the side wheel at one end of the steel wheel of the lighter grinding wheel through the feeding module. After completing the assembly on one side, the feeding module feeds and distributes the side wheel at the other end of the steel wheel.

[0029] The specific work steps are as follows:

[0030] (1) A steel wheel 1' is placed into the second material outlet 33, and the rotating wheel 1 is driven to rotate clockwise. Since the second material outlet 33 is located on the rotation trajectory of the second guide groove 24, the steel wheel 1' will eventually pass through the second guide groove 24 and enter the arc-shaped groove 21. The arc-shaped groove 21 carrying the steel wheel 1' will rotate synchronously with the rotating wheel 1 to the first material outlet 32.

[0031] (2) The side wheel 2' adapted to the first end of the steel wheel 1' is placed into the first material distribution port 32. Since the first material distribution port 32 is located on the rotation trajectory of the first guide groove 23, the side wheel 2' adapted to the first end of the steel wheel 1' will eventually pass through the second guide groove 24 and enter the arc-shaped groove 21, and fit into the first end of the steel wheel 1'.

[0032] (3) A stamping mechanism is used to axially stamp the steel wheel 1' in the arc-shaped groove 21 and the side wheel 2' that is fitted at the first end of the steel wheel 1' through the stamping port 22, and the side wheel is installed at the first end of the steel wheel 1' to obtain the semi-finished grinding wheel;

[0033] (4) Place the side wheel 3' adapted to the second end of the steel wheel 1' into the third feed port 34. Since the third feed port 34 is located on the rotation trajectory of the third guide groove 25, the side wheel 3' adapted to the second end of the steel wheel 1' will eventually pass through the third guide groove 25 into the arc-shaped groove 21 and fit into the second end of the steel wheel 1'.

[0034] (5) A stamping mechanism is used to axially stamp the steel wheel 1' in the arc-shaped groove 21 and the side wheel 3' that is fitted at the second end of the steel wheel 1' through the stamping port 22. The side wheel is installed at the second end of the steel wheel 1' to obtain the finished grinding wheel.

[0035] In order to coordinate with the operation of the stamping mechanism, the rotary wheel 1 can pause its rotation during the operation of the stamping mechanism. The stamping mechanism is not an improvement of this utility model, and the stamping mechanism can be implemented or referenced from existing technical solutions. Therefore, the specific structure of the stamping mechanism will not be described in detail in this utility model.

[0036] Because the feeding module 3 is located on the upper edge of the rotating wheel 1, and the bottom end of the feeding module 3 forms an arc-shaped limiting section 31 that mates with the bottom surface of the annular groove 2, the side wheels and steel wheels fed through the first feeding port 32, the second feeding port 33, and the third feeding port 34 will not come out of the arc-shaped groove 21. Only after the arc-shaped groove 21 on the rotating wheel 1 rotates to the point where it exits the arc-shaped limiting section 31 of the feeding module 3 will the finished grinding wheel in the arc-shaped groove 21 automatically come out of the arc-shaped groove 21.

[0037] More specifically, in order to ensure that the side wheels and steel wheels fed through the first feed port 32, the second feed port 33, and the third feed port 34 do not fall out of the arc-shaped groove 21, the surface of the arc-shaped limiting section 31 can be formed with guide rails corresponding to the side wheels and steel wheels respectively, and the side wheels and steel wheels will always roll and cooperate between the guide rails and the arc-shaped groove 21.

[0038] As can be seen from the above embodiments, the lighter grinding wheel assembly and feeding mechanism of this utility model feeds and assembles the side wheels at both ends of the steel wheel in two stages. The number of collision points that occur each time the side wheels are assembled is halved. The probability of the external force originally applied along the axial direction deviating from the axial direction during transmission is lower. The coaxiality of the side wheels and steel wheel of the lighter grinding wheel after assembly is significantly improved, and the defect rate is lower.

[0039] In a preferred embodiment, the clockwise rotation of the wheel 1 causes the arc of an arc-shaped groove 21 to move from the second feed port 33 to the first feed port 32 to be less than the arc of the interval between two adjacent arc-shaped grooves 21, making the feeding time of the steel wheel and the side wheel adapted to the first end of the steel wheel more compact, thereby improving production efficiency to a certain extent.

[0040] In another preferred embodiment, the rotary wheel 1 rotates clockwise so that the arc of an arc groove 21 moves from the first feed port 32 to the third feed port 34 is greater than the arc of the interval between two adjacent arc grooves 21, so that sufficient time and space are allocated for stamping and assembling the steel wheel and the side wheel adapted to the first end of the steel wheel.

[0041] In another preferred embodiment, the arc-shaped limiting section 31 is located on the clockwise side of the rotating wheel 1, and the bottom end of the feeding module 3 also forms a tangential separation section 30 that is tangential to the arc-shaped limiting section 31. Obviously, the tangential separation section 30 is involutely fitted with the bottom surface of the annular groove 2, so the finished grinding wheel in the arc-shaped groove 21 will gradually become a free state with no position restriction as the rotating wheel 1 rotates, and finally get out of the arc-shaped groove 21.

[0042] In another preferred embodiment, the rotating wheel 1 includes a pair of coaxially arranged turntables 11 and a coaxially arranged middle disc 12 clamped between the turntables 11. The diameter of the middle disc 12 is smaller than that of the turntables 11. The bottom surface of the annular groove 2 is formed by the outer circular surface of the middle disc 12, and the sidewalls of the annular groove 2 are formed by the rims of the turntables 11. The advantage of this arrangement is that it reduces the design and manufacturing difficulty of the rotating wheel 1.

[0043] In another preferred embodiment, the arc-shaped groove 21 has a coaxial arc-shaped rib 20 at the center of its arc surface, and the arc-shaped rib 20 is precisely centered within the opening range of the tail end of the second guide groove 24. Typically, the steel wheel of the grinding wheel is designed with a diameter smaller than that of the side wheel, and the height of the arc-shaped rib 20 is designed to be the difference in radius between the steel wheel and the side wheel. Thus, the steel wheel entering the arc-shaped groove 21 is precisely aligned coaxially with the side wheel under the support of the arc-shaped rib 20, which helps to ensure the coaxiality of the steel wheel and the side wheel after assembly.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
