Description

Technical Field

[0001] The utility model relates to the technical field of steel ball production and packaging, in particular to a steel ball precision counting device. Background Art

[0002] Bearing steel balls are small spheres made of chrome steel or carbon steel, usually spherical or cylindrical in shape. They are placed in the steel ball holder inside the bearing. Steel balls are one of the key components of the bearing. The packaging process of bearing steel balls generally includes a series of processes such as cleaning, collecting, counting, weighing, bagging, boxing, labeling, and shipping.

[0003] In the production process of steel balls, the steel balls need to be counted between the cleaning and collection process and the weighing process to ensure that the number of bearing steel balls in each package is within a reasonable error range. The existing counting method is that the steel balls are sent to the weighing process after the cleaning and collection process, and the operator manually counts the number of steel balls after visual inspection. After the counting is completed, the steel balls are bagged and shipped.

[0004] The above-mentioned method of manually counting steel balls has large errors and low accuracy due to visual inspection. It is difficult to accurately ensure that the number of bearing steel balls in each package is within a reasonable error range. It is time-consuming and labor-intensive, and leads to low production efficiency. Summary of the invention

[0005] In order to help solve the problem that the manual method of counting steel balls has low accuracy, is time-consuming and labor-intensive, and leads to low production efficiency, the utility model provides a precision steel ball counting device, which adopts the following technical solution: it includes a base, the base is provided with a plurality of material troughs for conveying steel balls, the base is provided with a counting frame, the counting frame is provided with counting units corresponding to the plurality of material troughs respectively, the base is provided with a bracket, and the bracket is provided with an interception unit for intercepting the steel balls in the material trough.

[0006] Through the above technical solution, the steel balls are transported by the trough and rolled to the bottom of the counting unit. The counting unit starts to record the number of steel balls passing through each trough. When the number of steel balls reaches the set value, the interception unit starts to intercept the steel balls in the trough that have not entered the counting unit, thereby ensuring that the number of bearing steel balls in each package is within a reasonable error range. The use of the counting unit and the interception unit saves time and effort, reduces labor costs, and improves the accuracy of steel ball counting, thereby improving production efficiency.

[0007] In a specific possible implementation mode, the material trough includes a supplementary trough and a plurality of conveying troughs, and the interception unit includes a coarse cutting component for intercepting the steel balls in the plurality of conveying troughs and a fine cutting component for intercepting the steel balls in the supplementary trough.

[0008] Through the above technical scheme, the material troughs are classified by using the replenishing trough and multiple conveying troughs. When the counting unit counts the steel balls in the multiple conveying troughs to a set value, the coarse cutting component intercepts the steel balls in the multiple conveying troughs, thereby achieving a rough count of the steel balls. Then the steel balls continue to be conveyed from the replenishing trough. When the counting unit counts the steel balls in the replenishing trough to a set value, the fine cutting component intercepts the steel balls in the separate replenishing trough, thereby achieving an accurate count of the steel balls. The use of the coarse cutting component and the fine cutting component improves the accuracy of the steel ball counting.

[0009] In a specific possible implementation scheme, the rough cutting assembly includes a first cylinder arranged on a bracket, a rough stop frame is provided at the output end of the first cylinder, and a plurality of rough stop blocks respectively matching with the conveying troughs are provided on the surface of the rough stop frame facing the base.

[0010] Through the above technical solution, the first cylinder is started, which drives the rough stop frame at the output end of the first cylinder to start, thereby driving a plurality of rough stop blocks to be inserted into a plurality of conveying grooves respectively, thereby realizing the interception of a plurality of conveying grooves.

[0011] In a specific possible implementation scheme, the precision cutting assembly includes a second cylinder arranged on a bracket, a fine stop frame is provided at the output end of the second cylinder, and a fine stop block matching the supplementary groove is provided on the surface of the fine stop frame facing the base.

[0012] Through the above technical solution, the second cylinder is started, which drives the fine stop frame at the output end of the second cylinder to start, thereby driving the fine stop block to be inserted into the supplementary groove, thereby realizing the separate interception of the steel balls in the supplementary groove.

[0013] In a specific possible implementation manner, arc grooves are respectively formed on the surfaces of the rough stop blocks facing the base.

[0014] Through the above technical solution, when the steel ball is transported to contact the arc groove, the arc surface of the arc groove is used to buffer the transition, reducing the possibility of the steel ball being damaged, thereby ensuring the surface quality of the steel ball.

[0015] In a specific feasible implementation scheme, the base is provided with a lifting assembly for driving the bracket to move in a vertical direction, the lifting assembly includes two support rods arranged on the base, a support plate is provided between the two support rods, a screw rod is passed through and threadedly connected to the support plate, the bracket is rotatably connected to the screw rod and the bracket passes through the two support rods.

[0016] Through the above technical solution, the two support rods limit the position of the bracket, reducing the possibility of the bracket being offset. When the height of the bracket needs to be adjusted to use different types of steel balls, the operator turns the screw rod, and the bolt drives the bracket to move up and down along the direction of the support rod, thereby adjusting the height of the bracket relative to the material trough, making it easier to deal with different types of steel balls and improving the applicability of the steel ball precision counting device.

[0017] In a specific possible implementation manner, the counting unit includes a plurality of optical fiber sensors arranged on a counting frame, and the plurality of optical fiber sensors correspond to a plurality of material troughs respectively.

[0018] Through the above technical solution, the optical fiber sensor has high sensitivity and can accurately measure tiny changes in physical quantities, thereby accurately counting the steel balls rolling in the trough.

[0019] In a specific implementation scheme, a mounting hole is provided on the counting frame, a mounting bolt matching the mounting hole is passed through the mounting hole, a mounting groove matching the mounting bolt is provided on the base, and the mounting bolt is threadedly connected in the mounting groove.

[0020] Through the above technical solution, the operator can remove the counting frame from the base by means of bolt disassembly, which is more flexible and facilitates the subsequent maintenance and replacement of the counting unit.

[0021] In a specific possible implementation scheme, an oil drain plate is provided on the base, the oil drain plate is arranged at the outlet end of the material trough and the oil drain plate is flush with the bottom of the material trough, and a plurality of oil drain holes are opened on the oil drain plate.

[0022] Through the above technical solution, when the steel ball rolls through the oil drain plate, excess lubricating grease on the surface of the steel ball is collected by the oil drain holes, thereby improving the quality of the finished steel ball.

[0023] In a specific possible implementation mode, the base is provided with two guide blocks located outside the material trough, and the two guide blocks are provided with inclined guide surfaces facing each other.

[0024] Through the above technical solution, the inclined guide surface guides the rolling trajectory of the steel balls, and a number of steel balls are concentrated to facilitate the operator to perform subsequent bagging operations.

[0025] In summary, the utility model has the following beneficial technical effects: the steel balls are conveyed and rolled to the bottom of the counting unit through the trough, and the counting unit starts to record the number of steel balls passing through each trough. When the number of steel balls reaches the set value, the interception unit starts to intercept the steel balls in the trough that have not entered the counting unit, thereby ensuring that the number of bearing steel balls in each package is within a reasonable error range. The use of the counting unit and the interception unit saves time and effort, reduces labor costs, and improves the accuracy of steel ball counting, thereby improving production efficiency.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 The utility model is described in further detail.

[0029] The utility model embodiment discloses a steel ball precision counting device.

[0030] Reference Figure 1 The steel ball precision counting device includes a base 1, on which a plurality of material troughs 2 for conveying steel balls are provided, the material troughs 2 include a supplementary trough 5 and a plurality of conveying troughs 6, a counting frame 3 is provided on the base 1, on which a mounting hole 19 is provided, in which a mounting bolt 18 matching the size of the mounting hole 19 is passed, a mounting groove matching the size of the mounting bolt 18 is provided on the base 1, and the mounting bolt 18 is threadedly connected in the mounting groove, and an operator can remove the counting frame 3 from the base 1 by disassembling the bolts, which is more flexible and convenient for subsequent maintenance and replacement of the counting unit.

[0031] Reference Figure 1, counting units corresponding to the plurality of troughs 2 are arranged on the counting frame 3, and the counting units include a plurality of optical fiber sensors 17 arranged on the counting frame 3. Specifically, a plurality of corresponding through holes are arranged on the counting frame 3 facing the plurality of troughs 2, and a plurality of optical fiber sensors 17 are inserted into the through holes corresponding to the plurality of troughs 2. The optical fiber sensor 17 has high sensitivity and can accurately measure small changes in physical quantities. When the steel ball in the trough 2 passes under the optical fiber sensor 17, the optical fiber sensor 17 detects the steel ball passing through and statistically feeds back the detection result, thereby accurately counting the steel balls rolling in the trough 2. In the embodiment of the utility model, the mounting hole 19 can be set as a waist-shaped hole to facilitate the adjustment of the position of the counting frame 3 relative to the base 1.

[0032] Reference Figure 1 The base 1 is bolted with an oil drain plate 20, which is arranged at the outlet end of the trough 2 and flush with the bottom of the trough 2. The oil drain plate 20 is provided with a number of evenly distributed circular oil drain holes 21. When the steel ball rolls through the oil drain plate 20, the excess lubricating grease on the surface of the steel ball is collected by the oil drain holes 21, thereby improving the quality of the finished steel ball. The base 1 is bolted with two guide blocks 22 located outside the trough 2. The two guide blocks 22 are relatively provided with inclined guide surfaces 23. The inclined guide surfaces 23 guide the rolling trajectory of the steel ball, and gather a number of steel balls together, so as to facilitate the operator to perform subsequent bagging operations.

[0033] Reference Figure 1 The base 1 is provided with a bracket 4, and a lifting assembly for driving the bracket 4 to move in the vertical direction is provided on the base 1. The bracket 4 is provided with an interception unit for intercepting the steel balls in the material trough 2, and the interception unit includes a rough cutting assembly for intercepting the steel balls in the multiple conveying troughs 6 and a fine cutting assembly for intercepting the steel balls in the supplementary trough 5. The rough cutting assembly includes a first cylinder 7 provided on the bracket 4, and a rough stop frame 8 is provided at the output end of the first cylinder 7. A plurality of rough stop blocks 9 respectively matching the conveying troughs 6 are provided on the surface of the rough stop frame 8 facing the base 1. The fine cutting assembly includes a second cylinder 10 provided on the bracket 4, and a fine stop frame 11 is provided at the output end of the second cylinder 10. A fine stop block 12 matching the supplementary trough 5 is provided on the surface of the fine stop frame 11 facing the base 1.

[0034] Therefore, the first cylinder 7 is started, and the rough stop frame 8 at the output end of the first cylinder 7 is started, thereby driving a plurality of rough stop blocks 9 to be inserted into a plurality of conveying grooves 6 respectively, so as to intercept a plurality of conveying grooves 6. The second cylinder 10 is started, and the fine stop frame 11 at the output end of the second cylinder 10 is started, thereby driving a fine stop block 12 to be inserted into the supplementary groove 5, so as to intercept the steel balls in the supplementary groove 5 individually. The material trough 2 is classified by using the supplementary groove 5 and the plurality of conveying grooves 6. When the counting unit counts the steel balls in the plurality of conveying grooves 6 to a set value, the rough interception component is started to intercept the steel balls in the plurality of conveying grooves 6, so as to roughly count the steel balls. Then, the steel balls continue to be transported from the supplementary groove 5. When the counting unit counts the steel balls in the supplementary groove 5 to a set value, the fine interception component intercepts the steel balls in the individual supplementary groove 5, so as to accurately count the steel balls. The rough interception component and the fine interception component are used to improve the accuracy of the steel ball counting.

[0035] Reference Figure 1 Several rough stop blocks 9 are respectively provided with arc grooves 13 on their surfaces facing the base 1. When the steel ball is transported to the arc groove 13 and contacts it, the arc surface of the arc groove 13 plays a role of buffering transition, reducing the possibility of the steel ball being damaged, thereby ensuring the surface quality of the steel ball. The fine stop block 12 can be set with reference to the arc groove 13 of the rough stop block 9.

[0036] Reference Figure 1 The lifting assembly includes two support rods 14 arranged on the base 1, and a support plate 15 is arranged between the two support rods 14. In the embodiment of the utility model, the two support rods 14 are arranged perpendicular to the base 1, and the support rods 14 are arranged parallel to the base 1. A screw 16 is passed through and threadedly connected to the support plate 15. The bracket 4 is rotatably connected to the screw 16 and the bracket 4 passes through the two support rods 14. In the embodiment of the utility model, a handle can be fixedly mounted on the end of the screw 16 away from the base 1 to facilitate the operator to rotate the screw 16.

[0037] Therefore, the two support rods 14 limit the position of the bracket 4, reducing the possibility of deflection of the bracket 4. When the height of the bracket 4 needs to be adjusted to accommodate different types of steel balls, the operator rotates the screw 16, and the bolt drives the bracket 4 to move up and down along the direction of the support rod 14, thereby adjusting the height of the bracket 4 relative to the trough 2, making it easier to cope with different types of steel balls and improving the applicability of the steel ball precision counting device.

[0038] The implementation principle of the embodiment of the utility model is as follows: the steel ball rolls in the material trough 2 for transportation. When the steel ball rolls below the optical fiber sensor 17, the optical fiber sensor 17 starts to record the number of steel balls passing through each material trough 2, wherein the material trough 2 includes a supplementary trough 5 and a plurality of conveying troughs 6. When the optical fiber sensor 17 counts the number of steel balls in the plurality of conveying troughs 6 to a set value, the first cylinder 7 is started, driving the rough stop frame 8 at the output end of the first cylinder 7 to start, and the rough stop frame 8 drives a plurality of rough stop blocks 9 to be respectively inserted into a plurality of conveying troughs 6. The steel balls are roughly counted by intercepting several conveying slots 6; then the steel balls continue to be transported from the separate supplementary slot 5. When the optical fiber sensor 17 counts the steel balls in the supplementary slot 5 to the set value, the second cylinder 10 is started, driving the fine stop frame 11 at the output end of the second cylinder 10 to start, and the fine stop frame 11 drives the fine stop block 12 to be inserted into the supplementary slot 5, so as to intercept the steel balls in the supplementary slot 5 separately, thereby achieving accurate counting of the steel balls and ensuring that the number of bearing steel balls in each package is within a reasonable error range. The counting unit and the interception unit save time and labor, reduce labor costs, and improve the accuracy of steel ball counting, thereby improving production efficiency.

[0039] This specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present application. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
