Description

Technical Field

[0001] The utility model relates to the technical field of hollow dividers, in particular to a clamping mechanism based on a divider. Background Art

[0002] A hollow divider is a high-precision rotary positioning device that plays a vital role in automated machinery. Its primary function is to convert the continuous rotation of the input shaft into intermittent rotation, oscillation, or linear motion of the output shaft. This conversion enables the hollow divider to achieve precise indexing and positioning, making it widely used in various automated equipment.

[0003] When the workpiece on the turntable is being processed, a positioning device is required to fix the workpiece. The existing fixing method mostly uses manual rotation of bolts to drive the clamping plate to clamp the workpiece on the turntable. This clamping method is not only inefficient, but also affected by human uncertainties, which will result in poor positioning effect. For example, when assembling the end cover on the ball valve, if the ball valve deflects on the turntable, the assembly effect and production efficiency will be reduced. Utility Model Content

[0004] In view of the deficiencies of the prior art, the present invention provides a clamping mechanism based on a divider to solve the problem of low workpiece clamping efficiency in the above-mentioned background technology.

[0005] In order to achieve the above technical objectives, the utility model proposes the following technical solutions: a clamping mechanism based on a divider, comprising a hollow divider, a base plate, a turntable and a circular disc, the hollow divider being arranged at the bottom of the base plate, the turntable being arranged on the rotating mounting portion of the hollow divider, the fixed mounting portion of the hollow divider extending upward, the circular disc being arranged on the fixed mounting portion of the hollow divider, a cam groove of a cam structure being provided on the surface of the circular disc, a plurality of workstation jigs being evenly arranged on the surface of the turntable and located around the circular disc, a clamping mechanism corresponding to the workstation jig being provided on the turntable and located on the inner side of the workstation jig, and the clamping mechanism can constitute a clamping and releasing action when the turntable rotates.

[0006] Furthermore, a first roller corresponding to the clamping mechanism is provided in the cam groove, and a tightening rod is provided on the first roller, and one end of the tightening rod is connected to the clamping mechanism.

[0007] Furthermore, the clamping mechanism includes a fixed seat, the bottom of which is slidably connected to a left clamp and a right clamp, and a limiting plate is provided on the fixed seat and above the left clamp and the right clamp, which is slidably connected via a sliding rod. Two symmetrical sliding grooves are provided on the limiting plate, and second rollers are provided in the sliding grooves. The bottoms of the second rollers are respectively connected to the left clamp and the right clamp through connecting rods. When the limiting plate slides, the left clamp and the right clamp can move relative to or away from each other.

[0008] Furthermore, anti-slip rubber blocks are provided on the opposing surfaces of the left clamp and the right clamp.

[0009] Furthermore, seals are provided on the bottom plate and around the bottom of the turntable.

[0010] Furthermore, a protective cover plate is provided on the top of the disc.

[0011] Compared with the existing technology, the beneficial effects produced by the utility model are: the utility model controls the intermittent rotation of the turntable through the hollow divider, and under the joint action of the cam groove, clamping mechanism, tightening rod, first roller and other structures, the workpiece can be clamped and released during the rotation of the turntable, which greatly improves the work efficiency. Compared with the traditional manual fixation, the mechanical automatic clamping can ensure the positioning effect; the clamping and release of the workpiece are achieved by converting the forward and backward movement of the limit plate into the left and right movement of the left clamp and the right clamp.

DETAILED DESCRIPTION

[0017] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0018] like Figure 1-4As shown, the utility model provides a clamping mechanism based on a divider, comprising a hollow divider 1, a base plate 2, a turntable 3 and a disc 4. The hollow divider 1 is arranged at the bottom of the base plate 2, the turntable 3 is arranged on the rotating mounting portion of the hollow divider 1, and the fixed mounting portion of the hollow divider 1 extends upward. The disc 4 is arranged on the fixed mounting portion of the hollow divider 1, and the disc 4 is located at the top of the turntable 3. A cam groove 5 of a cam structure is provided on the surface of the disc 4. Several station fixtures 6 are evenly arranged on the surface of the turntable 3 and located around the disc 4. A clamping mechanism 7 corresponding to the station fixture 6 is provided on the turntable 3 and on the inner side of the station fixture 6. When the turntable 3 rotates, it can constitute the action of clamping and releasing the clamping mechanism 7. A first roller 8 corresponding to the clamping mechanism 7 is provided in the cam groove 5, and a tightening rod 9 is provided on the first roller 8. One end of the tightening rod 9 is connected to the clamping mechanism 7.

[0019] like Figure 1-3 As shown, a stepper motor is installed at the bottom of the base plate 2, and the output shaft end of the stepper motor is connected to a driving pulley, and the input end of the hollow divider 1 is connected to a driven pulley. The driven pulley and the driving pulley are connected by a belt, and the work station fixture 6 is installed on the turntable 3 by bolt connection, which is convenient for installation and disassembly. The work station fixture 6 is used to perform preliminary positioning of the workpiece to be processed, so that it maintains a fixed position and direction during the processing, ensuring the accuracy and consistency of the processing results. The hollow divider 1 drives the turntable 3 to rotate intermittently. When the turntable 3 rotates, the position of the clamping mechanism 7 on the turntable 3 changes relative to the cam groove 5. The first roller 8 is located in the cam groove 5 and rolls along the cam groove 5. During the rotation of the turntable 3, the tightening rod 9 is extended and retracted. By changing the different positions of the roller 81 in the cam groove 5, the clamping or release of the workpiece by the clamping mechanism 7 is controlled. During the rotation of the turntable 3, the clamping and release of multiple clamping mechanisms 7 can be controlled, thereby realizing automated production and improving work efficiency.

[0020] The clamping mechanism 7 includes a fixed seat 71, and the bottom of the fixed seat 71 is slidably connected to a left clamp 72 and a right clamp 73. The left clamp 72 and the right clamp 73 are located at the top of the workpiece fixture 6. The fixed seat 71 and above the left clamp 72 and the right clamp 73 are slidably connected to a limiting plate 75 through a sliding rod 74. One end of the tightening rod 9 passes through the fixed seat 71 and is connected to the limiting plate 75. Two symmetrical and upwardly inclined sliding grooves 76 are provided on the limiting plate 75. Second rollers 77 are provided in the sliding grooves 76. The bottoms of the second rollers 77 are respectively connected to the left clamp 72 and the right clamp 73 through connecting rods. When the limiting plate 75 slides, the left clamp 72 and the right clamp 73 can move relative to or away from each other.

[0021] like Figure 4As shown, in this embodiment, by converting the forward and backward movement of the limit plate 75 into the action movement of the left clamp 72 and the right angle 73, when the first roller 8 at one end of the tightening rod 9 rotates in the cam groove 5, the tightening rod 9 drives the limit plate 75 to move forward and backward in the fixed seat 71. During the movement of the limit plate 75, the second roller 77 is driven to slide in the slide groove 76. When the tightening rod 9 extends in the fixed seat 71, the left clamp 72 and the right clamp 73 slide relative to each other to clamp the workpiece in the work station fixture 6. Conversely, the left clamp 72 and the right clamp 73 slide back to back to release the clamped workpiece.

[0022] Anti-slip rubber blocks are provided on the opposing surfaces of the left clamp 72 and the right clamp 73 .

[0023] like Figure 4 As shown, the anti-slip rubber blocks improve the clamping effect and protect the workpiece from surface damage.

[0024] A sealing strip 10 is provided on the bottom plate 2 and around the bottom of the turntable 3 .

[0025] like Figure 1 As shown, the bottom of the seal 10 is fixed to the base plate 2 by bolts. The seal 10 can prevent dust and other impurities from entering the gap between the turntable 3 and the base plate 2, and can also improve the aesthetics of the overall structure.

[0026] A protective cover plate 11 is provided on the top of the disc 4 .

[0027] like Figure 1 As shown, the protective cover plate 12 further enhances the aesthetics of the overall mechanism.

[0028] When the workpiece is in the working position, the workpiece is put into the workpiece fixture 6, and the hollow divider 1 drives the turntable 3 to do intermittent rotation. When the turntable 3 rotates, the workpiece fixture 6 and the clamping mechanism 7 are driven to rotate, and one end of the tightening rod 9 slides in the cam groove 5. When one end of the tightening rod 9 is located in the convex position of the cam groove 9, the tightening rod 9 pushes the limit plate 75 to slide forward. During the sliding process of the limit rod 75, the left clamp 72 and the right clamp 73 are driven to slide relative to each other under the action of the slide groove 76, clamping the workpiece in the workpiece fixture 6. When one end of the tightening rod 9 is located in the non-convex part of the cam groove 9, the tightening rod 9 pushes the limit plate 75 to slide backward, driving the left clamp 72 and the right clamp 73 to slide back and forth, thereby releasing the clamped workpiece.

Those skilled in the art may make various modifications, additions, or substitute similar methods to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
