Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical processing technology, and in particular relates to a divider. Background Technology
[0002] A divider is a device that uses mechanical or electronic control to achieve intermittent motion, converting continuous rotary motion into step-by-step intermittent motion. With the development of automation technology, dividers, as the core transmission device for achieving intermittent motion, have been widely used in food processing, pharmaceuticals, packaging, electronics manufacturing, and other fields.
[0003] Indexing machines are typically equipped with a locking mechanism that locks the spindle when it rotates one workstation angle. Existing locking mechanisms generally employ electromagnetic locking. For example, the servo indexing plate device for a CNC machine tool disclosed in application number CN2017200843872 describes a method where, when a magnetic pawl is needed to restrain the ratchet wheel, energizing an electromagnet generates a magnet with the same magnetic pole as the magnetic pawl. The magnetism of the electromagnet pushes the magnetic pawl against the ratchet wheel to lock it. When the magnetic pawl needs to retract from the ratchet wheel, energizing the electromagnet in the opposite direction generates a magnetism that attracts the magnetic pawl, causing it to retract from the ratchet wheel.
[0004] Because the electromagnetic locking mechanism has a response delay and relies on forward and reverse current control, there is a delay in the establishment and dissipation of the magnetic poles. This may cause lag in action, especially during frequent switching, which affects the accuracy of high-speed intermittent motion. Therefore, there is still room for improvement. Utility Model Content

The inner wall of the mounting cavity is provided with a second linkage mechanism or a guide mechanism.
[0011] When the driving mechanism drives the sliding seat to move backward and return to its initial position, the sliding seat causes the second positioning block to move to the right and disengage from the positioning groove through the second linkage mechanism.
[0012] Alternatively, when the driving mechanism drives the sliding seat to move forward, the positioning groove pushes the second positioning block to move backward, and the second positioning block disengages from the positioning groove through the guide mechanism during the backward movement.

[0018] Compared with the prior art, the advantages of this utility model are:
[0019] 1. By setting up a push block, a first positioning block, a first reset component, and a first linkage mechanism, when the drive mechanism drives the sliding seat to move forward, the push block first pushes the first linkage mechanism to separate the first positioning block from the positioning groove. Then, the rack and pinion gears cause the one-way bearing to rotate by one station angle in the locking direction. Finally, the push block disengages from the first linkage mechanism. Under the action of the first reset component, the first positioning block is inserted into a positioning groove to form a lock. Compared with the electromagnetic locking mechanism, this solution uses a mechanical linkage mechanism to complete the locking / unlocking, avoiding the delay problem of the establishment and disappearance of the electromagnetic poles, which helps to ensure the accuracy of high-speed intermittent motion. At the same time, it can also reduce the risk of failure due to electrical control failure.
[0020] 2. The mechanical transmission eliminates the need for current direction switching, making it particularly suitable for scenarios with frequent starts and stops or high-speed intermittent motion, thus solving the technical problem of lag in electromagnetic locking during frequent switching.
[0021] 3. The drive mechanism only needs to control the reciprocating linear motion of the rack, eliminating the need for complex current regulation, which reduces the difficulty of system control and maintenance costs. Attached Figure Description

Detailed Implementation
[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0033] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0034] Example 1: As Figures 1 to 4As shown, a divider includes a base 1 with a mounting cavity 101 and a main shaft 2. The bottom surface of the mounting cavity 101 has a shaft hole 102. The lower end of the main shaft 2 rotatably engages with the shaft hole 102. A positioning disc 3 and a one-way bearing 4 are fitted onto the main shaft 2. Multiple positioning grooves 301, evenly spaced along the circumference, are provided on the outer side of the positioning disc 3. A gear 5 is fixedly mounted on the outer side of the one-way bearing 4. The inner rings of the positioning disc 3 and the one-way bearing 4 are fixed to the main shaft 2. Conventionally, the upper part of the main shaft 2 extends out of the base 1 and is connected to a rotating disc (not shown in the figure). The rotating disc has multiple workstations, each corresponding to a different positioning groove 301. For example, in the attached figure, there are four positioning grooves 301, corresponding to a four-station divider. A rotating bearing is provided between the main shaft 2 and the shaft hole 102 to ensure smoother rotation.
[0035] In this embodiment, the mounting cavity 101 is provided with a sliding seat 103 that can move back and forth, a first positioning block 104 that can move left and right, and a first reset member 105 for driving the first positioning block 104 to reset. A spur rack 1031 for meshing with the gear 5 is provided on the right side of the sliding seat 103, and a push block 1032 is provided on the left side of the sliding seat 103. The first positioning block 104 is used to insert and cooperate with the positioning groove 301 located on the left side. The first positioning block 104 is connected to a first linkage mechanism 106 for transmission connection with the push block 1032. Under the action of the push block 1032 and the first linkage mechanism 106, the first positioning block 104 separates from the positioning groove 301, or is inserted into the positioning groove 301 to form a lock under the action of the first reset member 105, so as to prevent the positioning disk 3 and the main shaft 2 from rotating.
[0036] In this embodiment, the base 1 is provided with a drive mechanism 6 for driving the sliding seat 103 to move back and forth. When the drive mechanism 6 drives the sliding seat 103 to move forward, the first positioning block 104 is disengaged from the positioning groove 301 by pushing the first linkage mechanism 106 through the push block 1032. Then, the one-way bearing 4 is rotated by a station angle in the locking direction through the rack 1031 and the gear 5. Finally, the push block 1032 is disengaged from the first linkage mechanism 106. Under the action of the first reset member 105, the first positioning block 104 is inserted into a positioning groove 301 to form a lock. The drive mechanism 6 can be a commonly available cylinder. The cylinder body is fixed on the outer side of the base 1, and the telescopic rod of the cylinder extends into the mounting cavity 101 and is fixedly connected to the sliding seat 103.
[0037] Furthermore, a guide rail 107 extending in the front-to-back direction is provided in the mounting cavity 101, and the sliding seat 103 slides in cooperation with the guide rail 107 to improve stability during front-to-back movement; the first positioning block 104 is provided with a guide surface on the side facing the positioning disk 3 for quick reset.
[0038] Furthermore, the rack 1031 is movably disposed on the right side of the sliding seat 103. A positioning strip 115 is provided on the rear inner wall of the mounting cavity 101 for abutting against the rack 1031. Before the drive mechanism 6 drives the sliding seat 103 to move backward and return to the initial position, the positioning strip 115 abuts against the rack 1031, so that the rack 1031 is in a forward position. When the drive mechanism 6 drives the sliding seat 103 to move forward, the sliding seat 103 first drives the push block 1032 to move forward and push the first linkage mechanism 106, so that the first positioning block 104 is disengaged from the positioning groove 301. At the same time, the rack 1031 moves backward relative to the sliding seat 103 to a rearward position. Then the rack 1031 and the sliding seat 103 move forward synchronously. Through the rack 1031 and the gear 5, the one-way bearing 4 rotates one station angle in the locking direction.
[0039] It should be noted that, from a top-down view, the counterclockwise direction is the locking direction of the one-way bearing 4, and the clockwise direction is the free rotation direction of the one-way bearing 4.
[0040] Example 2: Figure 1 , Figures 3 to 5 As shown, the rest of the components are the same as in Embodiment 1, except that the bottom surface of the mounting cavity 101 is provided with a positioning shaft 108 and a positioning hook 109. One end of the positioning hook 109 is provided with a connecting hole 1091 for the positioning shaft 108 to pass through, and the first positioning block 104 is fixedly disposed on the right side of the other end of the positioning hook 109. In this structure, the positioning shaft 108 and the positioning hook 109 play a positioning role, ensuring that the first positioning block 104 can only move along a specified path, which helps to improve the stability of the structure. Conventionally, a rotary bearing is provided between the connecting hole 1091 and the positioning shaft 108 to make the rotation smoother.
[0041] In this embodiment, the first linkage mechanism 106 includes a first connecting seat 1061, a first rotating rod 1062, and a second reset member 1063. The first connecting seat 1061 is fixedly disposed on the upper end of the positioning hook 109. The middle part of the first rotating rod 1062 is rotatably connected to the upper end of the first connecting seat 1061 through a rotating shaft. A stop block 10611 is fixedly disposed on the upper end of the first connecting seat 1061. The stop block 10611 is located on the rear side of the left half of the first rotating rod 1062. The second reset member 1063 is used to drive the first rotating rod 1062 to rotate and make the left half of the first rotating rod 1062 abut against the stop block 10611. The front end of the push block 1032 is provided with an inclined guide surface 10321 that is inclined from front to back to left.
[0042] When the drive mechanism 6 drives the sliding seat 103 forward, the inclined guide surface 10321 of the push block 1032 contacts the right end of the first rotating rod 1062. Because the stop block 10611 blocks the rear side of the left half of the first rotating rod 1062, the first rotating rod 1062 cannot rotate. At this time, the push block 1032 will push the first rotating rod 1062, the first connecting seat 1061, the positioning hook 109, and the first positioning block 104 to the left. The first positioning block 104 disengages from the positioning groove 301, and then, through the rack 1031 and gear 5, the one-way bearing 4 rotates one station angle in the locking direction. Finally... When the push block 1032 disengages from the first rotating rod 1062, the first positioning block 104, under the action of the first reset member 105, inserts into a positioning groove 301 to form a lock. When the drive mechanism 6 drives the sliding seat 103 to move backward, the push block 1032 contacts the front side of the first rotating rod 1062, causing the first rotating rod 1062 to rotate. After the push block 1032 disengages from the first rotating rod 1062, the first rotating rod 1062 rotates in the opposite direction under the action of the second reset member 1063, returning to its initial position (the left half of the first rotating rod 1062 abuts against the stop block 10611). This structure is designed so that the first positioning block 104 disengages from the positioning groove 301 to unlock only when a station switching action is performed, which helps to ensure the stability of the spindle 2 in the static phase.
[0043] In this embodiment, the first reset member 105 includes a cylinder 1051 and a compression spring 1052. The cylinder 1051 is fixedly disposed on the left inner wall of the mounting cavity 101. One end of the compression spring 1052 extends into the cylinder 1051, and the other end of the compression spring 1052 abuts against the left side of the other end of the positioning hook 109.
[0044] In this embodiment, the second reset member 1063 is a torsion spring, one end of which is connected to the first rotating rod 1062, and the other end is connected to the left inner wall of the mounting cavity 101.
[0045] Furthermore, a rotatable roller is provided at the right end of the first rotating rod 1062. The roller contacts and engages with the inclined guide surface 10321 of the push block 1032, making the pushing process smoother.
[0046] Example 3: Figure 1 , Figure 6 and Figure 7As shown, the rest of the parts are the same as in Embodiment 2, except that the mounting cavity 101 is provided with a movable second positioning block 110 and a third reset member 111 for driving the second positioning block 110 to move to the left. A hydraulic buffer 114 is provided on the rear inner wall of the mounting cavity 101. The piston rod of the hydraulic buffer 114 abuts against the rear side of the second positioning block 110. The second positioning block 110 is used to insert and cooperate with the positioning groove 301 located on the right side. A second linkage mechanism 112 or a guide mechanism 113 is provided on the inner wall of the mounting cavity 101. When the second positioning block 110 is inserted into the positioning groove 301, it will prevent the positioning disk 3 and the main shaft 2 from rotating.
[0047] If a second linkage mechanism 112 is provided on the inner wall of the mounting cavity 101, when the drive mechanism 6 drives the sliding seat 103 to move backward and return to the initial position, the sliding seat 103 causes the second positioning block 110 to move to the right and disengage from the positioning groove 301 through the second linkage mechanism 112, so as to ensure that when the drive mechanism 6 drives the sliding seat 103 to move forward again, the second positioning block 110 is separated from the positioning groove 301, and the positioning disk 3 and the main shaft 2 can rotate.
[0048] If a guide mechanism 113 is provided on the inner wall of the mounting cavity 101, when the drive mechanism 6 drives the sliding seat 103 to move forward, the positioning groove 301 pushes the second positioning block 110 to move backward. At the same time, the second positioning block 110 disengages from the positioning groove 301 through the guide mechanism 113 during the backward movement, so as to avoid interference with the second positioning block 110 when the one-way bearing 4 is driven to rotate in the locking direction by the drive mechanism 6.
[0049] In this embodiment, the third reset component 111 includes a connecting strip 1111 with a connection port 11111 at one end, an elastic sheet 1112, and a reset torsion spring 1113. The connecting strip 1111 is sleeved on the spindle 2 through the connection port 11111, and the connecting strip 1111 is rotatably engaged with the spindle 2. One end of the elastic sheet 1112 is fixedly connected to the other end of the connecting strip 1111, and the other end of the elastic sheet 1112 is fixedly connected to the second positioning block 110. The reset torsion spring 1113 is sleeved on the outside of the spindle 2. One end of the reset torsion spring 1113 is fixedly connected to the inner bottom surface of the mounting cavity 101, and the other end of the reset torsion spring 1113 is connected to the connecting strip 1111. The inner bottom surface of the mounting cavity 101 may be provided with an insertion hole. One end of the reset torsion spring 1113 is inserted into the insertion hole, and the other end of the reset torsion spring 1113 is hooked onto the side of the connecting strip 1111 using a hook-like structure. The structure utilizes the elastic force of the elastic sheet 1112 to achieve the reset function of the second positioning block 110, and uses the elastic force of the reset torsion spring 1113 to achieve the reset function of the connecting strip 1111.
[0050] In this embodiment, a first column 1101 is fixedly installed at the upper end of the second positioning block 110, and a second column 11112 is fixedly installed at the upper end of the connecting strip 1111. The first column 1101 is connected to the second column 11112 via a second torsion spring 1114. This structure utilizes the elastic force of the second torsion spring 1114 to achieve the reset function of the second positioning block 110. The elastic sheet 1112 and the second torsion spring 1114 cooperate to help the second positioning block 110 reset quickly. Furthermore, there are two connecting strips 1111, which are symmetrically distributed on the upper and lower sides of the positioning disk 3. The second column 11112 is fixedly installed on the upper connecting strip 1111, and the other end of the reset torsion spring 1113 is hooked onto the lower connecting strip 1111.
[0051] Example 4: Figure 1 , Figure 3 and Figure 8 As shown, the rest is the same as in Embodiment 3, except that the second linkage mechanism 112 includes a second connecting seat 1121, a second rotating rod 1122, a third connecting seat 1123, a third rotating rod 1124, and a third torsion spring 1125. The second connecting seat 1121 is fixedly installed on the rear inner wall of the mounting cavity 101. The middle part of the second rotating rod 1122 is rotatably connected to the second connecting seat 1121 through a rotating shaft. The third connecting seat 1123 is fixedly installed on the right inner wall of the mounting cavity 101. The third rotating rod 1124 is L-shaped. The bent part of the third rotating rod 1124 is rotatably connected to the third connecting seat 1123 through a rotating shaft. One end of the second rotating rod 1122 is connected to one end of the third rotating rod 1124. The other end of the third rotating rod 1124 is connected to the first column 1101. One end of the third rotating rod 1124 is connected to the rear inner wall of the mounting cavity 101 through the third torsion spring 1125.
[0052] When the drive mechanism 6 drives the sliding seat 103 to move backward and return to the initial position, the sliding seat 103 pushes the other end of the second rotating rod 1122 backward, and one end of the second rotating rod 1122 rotates forward, causing one end of the third rotating rod 1124 to also rotate forward. The other end of the third rotating rod 1124 rotates to the right, causing the first column 1101 and the second positioning block 110 to move to the right. At this time, the second positioning block 110 disengages from the positioning groove 301.
[0053] When the drive mechanism 6 drives the sliding seat 103 to move forward, the sliding seat 103 separates from the other end of the second rotating rod 1122. The second rotating rod 1122 and the third rotating rod 1124 are reset by the elastic force of the third torsion spring 1125. The second positioning block 110 is reset under the action of the second torsion spring 1114 and the elastic plate 1112 and is inserted into a positioning groove 301.
[0054] Example 5: Figure 6 and Figure 9 As shown, the rest is the same as in Embodiment 3, except that the guide mechanism 113 includes a fourth connecting seat 1131 fixedly disposed on the inner wall of the right side of the mounting cavity 101. A wedge block 1132 is fixedly disposed on the front side of the fourth connecting seat 1131. The right side of the wedge block 1132 is an inclined surface that slopes from front to back and backward. The first column 1101 abuts against the inclined surface.
[0055] When the drive mechanism 6 drives the sliding seat 103 to move forward, the positioning disk 3 rotates, and the positioning groove 301 pushes the second positioning block 110 to move backward. The first column 1101 on the second positioning block 110 moves to the right along the inclined plane during the backward movement, and finally causes the second positioning block 110 to disengage from the positioning groove 301. When rotating by one station angle, the second positioning block 110 will be reset under the action of the second torsion spring 1114 and the elastic sheet 1112, and finally inserted into the next positioning groove 301.
[0056] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
