Description

Technical Field

[0001] The invention belongs to the technical field of cam dividers, and in particular relates to a cam divider with a changeable number of workstations. Background Art

[0002] Cam divider, also known as cam indexer or intermittent divider, is a high-precision rotary device. The main types of cam dividers include arc cam and plane cam. The arc cam divider converts continuous input motion into intermittent output motion by meshing the arc conjugate cam on the input shaft with the indexing disk on the output shaft vertically without gap. The plane cam divider achieves the same function by meshing the plane conjugate cam on the input shaft with the indexing disk on the output shaft parallel without gap.

[0003] The flat cam divider has the ability to output small divisions and large steps, and is suitable for occasions that require fewer stops in one cycle. For example, flat cam dividers are widely used in various paper box die-cutting machines and fruit milk jelly filling and molding machines. The curved cam divider is famous for its high precision, high speed, high torque, and small size. Therefore, the curved cam divider is widely used in various automatic machines that require stepping drives, such as pharmaceutical machinery, tobacco machinery, printing machinery, food packaging machinery, and machine tool processing centers.

[0004] However, in some application scenarios in actual production, due to the different products produced, it is necessary to adjust the number of workstations and the number of stops within a cycle according to the product production requirements to facilitate the processing or operation of the products during production. This requires the cam divider to have the ability to adjust the number of stops. However, the existing technology can only adjust the number of stops within a cycle by directly converting the production line, but cannot achieve it directly by adjusting the cam divider, and cannot meet diverse production needs.

[0005] Based on this, in order to adjust the number of pauses of the cam divider in one cycle, a cam divider with a changeable number of workstations is proposed. Summary of the invention

[0006] In order to solve the above problems existing in the prior art, the present invention provides a cam divider with a changeable number of workstations.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A cam divider with a changeable number of workstations of the present invention comprises a housing, a stepping assembly and a cam assembly, wherein the housing comprises an operating chamber, the stepping assembly comprises a dividing plate and a plurality of rotating wheels, the cam assembly comprises a rotating shaft and a cam, the cam is connected to the rotating shaft in a transmission manner, the dividing plate and the rotating shaft are both rotatably connected to the operating chamber and their axes are perpendicular to each other, a plurality of mounting holes are arranged at the bottom of the dividing plate, a plurality of rotating wheels are detachably rotatably connected to the mounting holes, a spiral groove is arranged on the axial surface of the cam, the spiral groove comprises a stepping section and a stopping section, the spiral groove is meshed with a plurality of rotating wheels, the spiral groove of the cam is meshed with the rotating wheels and rotates for stepping rotation of the dividing plate;

[0009] A plurality of mounting groups with increasing diameters are arranged at the bottom of the dividing plate, and the mounting holes in the plurality of mounting groups are increased in sequence according to the increasing diameters and are arranged in a circular array based on the center of the circle. Each of the mounting groups corresponds to a workstation number pattern, and the ratio of the number of mounting holes between the plurality of mounting groups is the same as the ratio of the diameters between the plurality of mounting groups.

[0010] Furthermore, the lengths of the wheels of the plurality of installation groups decrease successively from being close to the center of the circle to being far away from the center of the circle.

[0011] Furthermore, the diameters of the wheels of the plurality of installation groups are successively increased and decreased as the diameters of the plurality of installation groups are successively increased.

[0012] Furthermore, the cam is detachably connected to the rotating shaft, and the cams include a plurality of cams, each of which is provided with a spiral groove width matching a plurality of rotating wheels of different diameters, and each of the cams is used in pair with a rotating wheel of a corresponding diameter.

[0013] Furthermore, the rotating shaft is horizontally slidably connected in the operating cavity.

[0014] Furthermore, it also includes a driving motor, which is arranged outside the shell, and the output shaft of the driving motor is drivingly connected to the rotating shaft.

[0015] Furthermore, the cam is a combined cam, and the cam is divided into two detachable combined blocks based on its axis, and the two combined blocks are connected by a connecting piece.

[0016] Furthermore, an equipment cavity is provided in the shell, and a cam and a rotating wheel for replacement are placed in the equipment cavity.

[0017] The beneficial effects of the present invention are as follows: by arranging several layers of mounting groups at the bottom of the indexing plate, each mounting group has multiple mounting holes, and the mounting holes on the same mounting group form an annular array based on the center of the indexing plate, and the diameter of the annular array formed by each mounting group is different; the number ratio of the mounting holes between the several mounting groups is the same as the diameter ratio between the several mounting groups. For example, the mounting group in the innermost layer has four mounting holes for mounting the rotating wheel. In order to adjust the number of workstations to five, it is necessary to set the number of mounting holes of the mounting group in the outer layer to five, and at the same time, it is necessary to set the diameter of the mounting group with four mounting holes to By increasing the number of holes by one quarter, the circumference of the installation group can be increased by one quarter, which is used to add a mounting hole and keep the distance between every two mounting holes unchanged. Since the distance between the mounting holes on each mounting group is the same, when the cam engages with the wheels on different mounting groups, it can just connect to the next wheel after driving the previous wheel, so that the dividing plate also rotates accordingly. After the number of mounting holes increases from four to five, the angle of each rotation of the dividing plate can also change arbitrarily, and the number of stops also changes at the same time, which ensures the transmission accuracy while realizing the adjustment of the number of stops and the number of workstations.

[0031] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0032] like Figure 1-11 As shown, a cam divider with a changeable number of workstations of the present invention comprises a housing, a stepping assembly and a cam assembly, wherein the housing comprises an operating chamber 6, the operating chamber 6 is provided with a rear cover plate 8 which can be detachably covered, the stepping assembly comprises a dividing plate 2 and a plurality of rotating wheels 3, the cam assembly comprises a rotating shaft 5 and a cam 1, the cam 1 is transmission-connected to the rotating shaft 5, the dividing plate 2 and the rotating shaft 5 are both rotationally connected in the operating chamber 6 and their axes are perpendicular to each other, a plurality of mounting holes are provided at the bottom of the dividing plate 2, a plurality of rotating wheels 3 are detachably and rotationally connected to the mounting holes, a spiral groove is provided on the axial surface of the cam 1, the spiral groove comprises a stepping section and a stop section, the spiral groove meshes with a plurality of rotating wheels 3, the spiral groove of the cam 1 meshes with the rotating wheels 3 and rotates for stepping rotation of the dividing plate 2; a plurality of mounting groups with successively increasing diameters are provided at the bottom of the dividing plate 2, the mounting holes in the plurality of mounting groups increase successively according to the increasing diameters and are all in a ring array based on the center of the circle, and each mounting group corresponds to a mode of the number of workstations;

[0033] The cam divider is used to rotate and stop the steps in the production process, that is, to stop at a workstation or operating position, and then rotate to the next step after being operated by a staff member or machine equipment. The stop and rotation time between each step is equal. Unlike the rotation controlled by the driving motor 4, the cam divider can ensure the rotation accuracy through the meshing transmission of the cam 1 and the wheel 3. In order to ensure the rotation accuracy, the existing cam divider cannot adjust the number of workstations according to different needs, which causes inconvenience in use and increased cost of use.

[0034] Therefore, it is necessary to ensure the rotation accuracy of the cam divider while also being able to adjust the number of workstations and the number of stops on the dividing plate 2. The cam divider generally meshes with a number of rotating wheels 3 in a circular array at the bottom of the dividing plate 2 through a special cam 1 to form a structure similar to a worm gear. The rotating wheel 3 is driven by the cam 1 to cause the dividing plate 2 to rotate and stop. Therefore, the cam 1 needs to have a stepping section and a stopping section. The stepping section is a spiral structure. After the spiral groove in this section rotates, the rotating wheel 3 moves with the rotation of the spiral groove. The stopping section is a spiral groove connected to the stepping section and parallel to the radial surface of the cam 1. The rotating wheel 3 in the stopping section will not move in the horizontal direction and is in a stopped state.

[0035] Then, several mounting groups are arranged at the bottom of the dividing plate 2, each mounting group having a plurality of mounting holes, and the mounting holes on the same mounting group form an annular array based on the center of the dividing plate 2, and the diameter of the annular array formed by each mounting group is different, and the number of mounting holes of different mounting groups increases from the inside to the outside at the center of the bottom of the dividing plate 2. Since the distance that the same cam 1 pushes the dividing plate 2 to move after meshing with the rotating wheel 3 is not adjustable, and in order for the same cam 1 to be able to connect the previous rotating wheel 3 with the next rotating wheel 3 during the rotation process, it is necessary to ensure that the distances between all adjacent mounting holes on any group of mounting groups are equal, and mounting groups with different diameters are arranged on the dividing plate 2. Due to the different diameters, in order to ensure that the distances between two adjacent mounting holes are equal, it is necessary to increase the number of mounting holes of the mounting group accordingly, and in this way, the number of pauses and the number of workstations of the cam divider are adjusted, and since the increased number of mounting holes matches and corresponds to the diameter of the mounting group, the rotating wheels 3 on different mounting groups can mesh well with the spiral grooves on the cam 1, and the transmission accuracy is ensured while the number of pauses and the number of workstations of the cam divider are adjusted.

[0036] Since the calculation formula for the circumference of a circle is C=πd, when the diameter of the installation group doubles, the circumference of the installation group also doubles. On this basis, the number of installation holes on the installation group also needs to be doubled to ensure that the distance between two adjacent installation holes is equal; that is, the ratio of the number of installation holes between several installation groups is the same as the ratio of the diameters between several installation groups. For example, the installation group in the innermost layer has four installation holes for installing the rotating wheel 3. In order to adjust the number of workstations to five, the number of installation holes of the installation group in the outer layer needs to be set to five, and at the same time, the diameter needs to be increased by one quarter based on the diameter of the installation group with four installation holes, so that the circumference of the installation group can be increased by one quarter, which is used to add one installation hole and maintain the distance between every two installation holes. The cam 1 remains unchanged because the distances between the mounting holes on each mounting group are the same. Therefore, when the cam 1 meshes with the wheels 3 on different mounting groups, it can just connect to the next wheel 3 after driving the previous wheel 3, so that the dividing plate 2 also rotates accordingly. After the number of mounting holes increases from four to five, the angle of each rotation of the dividing plate 2 also changes randomly, and the number of pauses also changes. At the same time, in order to avoid the interference between the wheels 3 between different mounting groups and the cam 1 during use, which makes it difficult for the cam 1 to rotate, only one mounting group can be installed on the dividing plate 2 at the same time. When the number of pauses needs to be adjusted, all the wheels 3 on the previous mounting group need to be removed from the mounting holes, and then installed on the mounting holes of the target number of mounting groups that need to be adjusted.

[0037] In the above embodiment, only one installation group can be installed on the dividing plate 2 at the same time. For ease of use, multiple installation groups can also be directly arranged on the dividing plate 2 at the same time. At the same time, in order to prevent the wheels 3 of several installation groups arranged at the bottom of the dividing plate 2 from interfering with each other when meshing with the cam 1, in one embodiment, the lengths of the wheels 3 of several installation groups decrease successively from close to the center of the circle to far away from the center of the circle; that is, the length of the wheel 3 close to the center of the circle is longer, and the length of the wheel 3 far away from the center of the circle is shorter. When the cam 1 meshes with the wheels 3 on different installation groups, if it meshes with the wheel 3 close to the center of the circle, the meshing portion of the cam 1 and the wheel 3 is at a portion where the wheel 3 protrudes from the wheels 3 of other installation groups.

[0038] When different installation groups are used, although the distance between every two adjacent wheels 3 is equal, when the length of the cam 1 remains unchanged, when the diameter of the installation group gradually increases, the angle between each wheel 3 increases due to the increase in the number of wheels 3, which easily causes the cam 1 to contact multiple wheels 3 on the same installation group at the same time, causing the cam 1 to get stuck during the rotation process, and then causing the rotation of the indexing plate 2 to get stuck. In order to avoid this problem, in one embodiment, the diameters of the wheels 3 of several installation groups are successively reduced as the diameters of the several installation groups become larger;

[0039] By reducing the diameter of the wheel 3 while expanding the diameter of the installation group, the distance between the wheels 3 in the installation group can be further increased to prevent the cam 1 from meshing with two wheels 3 at the same time, and the diameter of the wheel 3 gradually increases as the diameter of the installation group becomes smaller. This is because the number of wheels 3 decreases as the diameter of the installation group decreases. The smaller number of wheels 3 means that the angle of rotation of the dividing plate 2 is larger each time the cam 1 drives the wheel 3 to move, and the torque that the cam 1 needs to output is larger. Therefore, by setting a larger wheel 3, it can also match the torque of the cam 1. After the diameter of the installation group is increased, the number of wheels 3 also increases. Then, the angle of rotation of the dividing plate 2 after the cam 1 is driven to rotate is reduced, and the torque that the cam 1 needs to output is also smaller. A smaller wheel 3 can be used to match it, and the friction can also be reduced.

[0040] Since in the above embodiment, the diameter of the rotating wheel 3 is gradually reduced as the diameter of the installation group increases, in order to ensure that the same cam 1 can be used with the rotating wheels 3 on all the installation groups, it is necessary to make the width of the spiral groove on the cam 1 able to meet the use of the largest rotating wheel 3. Although a wider spiral groove can also be used with a rotating wheel 3 with a smaller diameter, in this case, since only one side of the spiral groove of the cam 1 is in contact with the rotating wheel 3, an error will occur in the rotation of the dividing plate 2, that is, the dividing plate 2 may rotate back after rotating an angle. In order to avoid possible errors, it is necessary to adjust the width of the spiral groove of the cam 1 as the diameter of the rotating wheel 3 changes. Therefore, the cam 1 is detachably connected to the rotating shaft 5. The cam 1 includes a plurality of cams 1, each of which is provided with a spiral groove width matching a plurality of rotating wheels 3 with different diameters, and each cam 1 is used in pair with a rotating wheel 3 of a corresponding diameter.

[0041] The cam 1 is detachably connected to the rotating shaft 5. When the installation group needs to be adjusted, the wheel 3 on the installation group needs to be removed and then installed on the target installation group. In this process, the cam 1 is replaced at the same time to match the diameter of the corresponding wheel 3 to avoid errors when the cam 1 is engaged with the wheel 3. The rotation accuracy is guaranteed while the number of stops and the number of workstations of the dividing plate 2 are adjusted.

[0042] In the above embodiment, the cam 1 is meshed with the wheels 3 on the mounting groups of different diameters. However, when the position of the cam 1 remains unchanged, the distance between the wheels 3 on the different mounting groups and the cam 1 will also change accordingly. The meshing connection parts between the wheels 3 and the cam 1 near the center of the indexing plate 2 are relatively small, and teeth may be disengaged, resulting in the indexing plate 2 being unable to be driven by the cam 1 when the load is heavy. In order to avoid this problem, in one embodiment, the rotating shaft 5 is horizontally slidably connected to the operating chamber 6;

[0043] The horizontal sliding connection mode of the rotating shaft 5 in the running chamber 6 can be achieved by rotating the rotating shaft 5 to be connected to a connecting block provided with a bearing, and then making the connecting block slidably connected to the side wall of the running chamber 6. A slide groove can be provided on the side wall of the running chamber 6, and the connecting block is set in the slide groove; or cylinders are provided on both sides of the connecting block, and the cylinders are provided on the side walls of the running chamber 6. The position of the rotating shaft 5 is adjusted by the cylinder, and then the position of the cam 1 and the rotating wheel 3 is adjusted. When adjusting the installation group connected to the rotating wheel 3, it is necessary not only to replace the corresponding cam 1, but also to adjust the position of the rotating shaft 5 to which the cam 1 is rotatably connected, so that the meshing of the cam 1 and the rotating wheel 3 is in the best position.

[0044] In one embodiment, it also includes a drive motor 4, which is arranged outside the shell, and the output shaft of the drive motor 4 is connected to the rotating shaft 5 in a transmission manner; the drive motor 4 is used to drive the rotating shaft 5 to rotate. In the above embodiment, the rotating shaft 5 needs to adjust its position as needed. In order to make the drive motor 4 move synchronously, a sliding platform can also be set on the outer wall of the shell for installing the drive motor 4, so that the movement of the rotating shaft 5 is driven by the sliding of the drive motor 4.

[0045] When replacing the installation group where the rotating wheel 3 is located, the cam 1 needs to be replaced accordingly, and the general cam 1 is rotatably connected to the rotating shaft 5. When replacing, the entire rotating shaft 5 needs to be disassembled, and then the corresponding cam 1 needs to be reinstalled. The equipment connected by the general cam divider is relatively complicated, and it is inconvenient to frequently disassemble the rotating shaft 5 for replacement. Therefore, in order to improve the replacement efficiency, in one embodiment, the cam 1 is a combined cam 1, and the cam 1 is divided into two detachable combined blocks based on its axis, including a first half cam 101 and a second half cam 102. The first half cam 101 and the second half cam 102 of the two combined blocks are provided with corresponding matching holes 103, and are connected through the matching holes 103 by a connecting piece;

[0046] That is, the cam 1 is composed of two assembly blocks, and can be connected by bolts to form a complete cam 1. When it needs to be installed on the rotating shaft 5, the two assembly blocks are respectively attached to the two sides of the rotating shaft 5 and combined into a whole, and then connected by bolts; similarly, when it needs to be dismantled and replaced, the bolts are loosened and the two assembly blocks are removed separately.

[0047] Since it is necessary to replace wheels of different diameters and cams matching therewith in different usage scenarios, in order to facilitate replacement and improve replacement efficiency, in one embodiment, an equipment cavity 7 is further provided in the shell, and a cam rod for placing the cam 1 and a wheel rod for placing the wheel 3 are provided in the equipment cavity 7. The cam 1 and the wheel for replacement are placed in the equipment cavity 7, the cam 1 is placed on the cam rod, and the wheel 3 is placed on the wheel rod; cams 1 and wheels of different sizes are placed in the equipment cavity 7, and wheels of corresponding sizes are placed in the same group as the corresponding cams 1, which is convenient for corresponding use during replacement, thereby improving replacement efficiency.

[0048] In one embodiment, the number of workstations can be adjusted by directly changing the number of wheels. When the number of wheels 3 is changed, a corresponding number of wheels 3 are installed on the indexing plate 2. Figure 6 As shown, when the indexing plate 2 is equipped with four rotating wheels 3, the first rotating wheel 301, the second rotating wheel 302, the third rotating wheel 303 and the fourth rotating wheel 304 are symmetrically placed on the same circumference of the indexing plate 2; Figure 7 As shown, when the indexing plate 2 is equipped with 6 wheels 3, the first wheel 301, the second wheel 302, the third wheel 303, the fourth wheel 304, the fifth wheel 305 and the sixth wheel 306 are symmetrically placed on the same circumference of the indexing plate 2; Figure 8 As shown, when the indexing plate 2 is equipped with 8 wheels 3, the first wheel 301, the second wheel 302, the third wheel 303, the fourth wheel 304, the fifth wheel 305, the sixth wheel 306, the seventh wheel 307 and the eighth wheel 308 are symmetrically placed on the same circumference of the indexing plate 2; Fig. 9 As shown, when the dividing plate 2 is equipped with 12 wheels 3, the first wheel 301, the second wheel 302, the third wheel 303, the fourth wheel 304, the fifth wheel 305, the sixth wheel 306, the seventh wheel 307, the eighth wheel 308, the ninth wheel 309, the tenth wheel 310, the eleventh wheel 311 and the twelfth wheel 312 are symmetrically placed on the same circumference of the dividing plate 2.

[0049] When using a rotating wheel 3 with the same diameter, when the rotating wheel 3 is placed on a circle with different diameters, the position of the rotating shaft 5 needs to be changed accordingly, such as Fig.11 As shown, when the circumferential diameters of the installation positions of the first rotating wheel 301, the second rotating wheel 302, the third rotating wheel 303 and the fourth rotating wheel 304 on the dividing plate 2 change from large to small, the installation flange 401 changes the installation position accordingly, driving the drive motor 4 to change the position following the rotating shaft 5, thereby ensuring that the first rotating wheel 301, the second rotating wheel 302, the third rotating wheel 303 and the fourth rotating wheel 304 after the change of position are correctly engaged with the cam 1, thereby realizing the load transformation of the cam divider.

[0050] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
