Description

Technical Field

[0001] The utility model relates to the field of machining, in particular to an angular positioning device. Background Art

[0002] In the field of machining, angular positioning of rotary workpieces is a common requirement. Although existing automation technologies have reached a relatively high level, in terms of the radial rotation positioning of spline-type rotary bodies, existing solutions can either only target workpieces of a single specification or have complex structures, making it difficult to meet the diverse industrial application requirements.

[0003] In response to this problem, the present application innovatively proposes an angular positioning device with a simple structure and convenient operation. This device can not only adapt to workpieces of different sizes, but also, through optimized design, greatly improve the positioning accuracy and operation convenience, bringing a new solution. Summary of the Utility Model

[0004] Aiming at the above-mentioned shortcomings of the prior art, the purpose of the present utility model is to provide an angular positioning device to solve one or more problems in the prior art.

[0005] To achieve the above purpose, the technical solution of the present utility model is as follows:

[0006] An angular positioning device includes a positioning device and a clamping device. The positioning device includes a base, a rotating mechanism, and a feeding mechanism. The rotating mechanism and the feeding mechanism are adjacent to each other on the base. The fixed end of the feeding mechanism is connected to the base. The rotating mechanism includes a bracket, a movable positioning member, and a movable connecting component. The bracket is vertically fixed on the base, and the positioning member is arranged on one side of the bracket through the connecting component. The positioning member has positioning teeth, and the clamping device is connected to the feeding mechanism. In the above technical solution, this design realizes the precise positioning and conveying of workpieces through the coordinated work of the base, the rotating mechanism, and the feeding mechanism, improving the flexibility and adaptability of the device.

[0007] The rotating mechanism further includes a reducer and a servo motor. The reducer is arranged on one side of the bracket, the servo motor drives the reducer, and the feeding mechanism is electrically connected to the servo motor. In the above technical solution, through the combined use of the servo motor and the reducer, the rotation speed and position of the rotating mechanism can be precisely controlled, thereby achieving high-precision positioning.

[0008] The output end of the speed reducer passes through the through hole on the bracket. The connecting component includes a fixed disk, a support disk, a rod, and a spring. The fixed disk is connected to the output end of the speed reducer from the other side of the bracket. The fixed disk is provided with a plurality of first holes, and the support disk is provided with a plurality of second holes. The first holes, the second holes, the rod, and the spring are adapted. The rod sequentially passes through the second hole, the spring, and the first hole to connect the support disk to the fixed disk. Both ends of the spring respectively abut against the fixed disk and the support disk. In the above technical solution, the design of this connecting component allows the positioning member to move flexibly under the action of the spring while maintaining the stability of positioning, improving the positioning accuracy and the durability of the equipment.

[0009] The clamping device includes a two-jaw cylinder and a limit plate. The limit plate includes a bottom plate and a side plate. The two-jaw cylinder is arranged on one side of the bottom plate, and the side plate is fixedly connected to the other side of the bottom plate. A reinforcing rib is also provided between the side plate and the bottom plate. The bottom plate is connected to the movable end of the feeding mechanism. In the above technical solution, the design of the clamping device ensures the stability of the workpiece during transportation and positioning, and the use of the reinforcing rib enhances the strength and rigidity of the structure.

[0010] The two-jaw cylinder has two symmetrically arranged clamping jaws. Fixed slots are opened at symmetric positions on the two clamping jaws, and anti-slip lines are provided in the fixed slots. In the above technical solution, the design of the symmetrically arranged clamping jaws and the anti-slip lines improves the uniformity and reliability of clamping, preventing the workpiece from sliding during the processing.

[0011] The positioning member is detachably arranged on the connecting component. The positioning member is columnar, and a through hole is opened along its axis. The positioning teeth are fixedly arranged inside the through hole. In the above technical solution, the detachable design of the positioning member facilitates maintenance and replacement, and the positioning teeth inside the through hole provide stable positioning points.

[0012] The two fixed slots form a clamping space, and the geometric center point of this space is located on the axis of the positioning member. In the above technical solution, the alignment of the geometric center of the clamping space with the axis of the positioning member ensures the symmetry and balance of the workpiece during clamping, which is beneficial to improving the processing accuracy.

[0013] The positioning member is columnar, and a through hole is opened along its axis. The positioning teeth are detachably arranged on the connecting component through a locking structure. In the above technical solution, the use of the locking structure allows for the quick removal of the positioning teeth, facilitating the replacement of different types of positioning teeth according to processing requirements, and improving the versatility and adaptability of the equipment.

[0014] Compared with the prior art, the beneficial technical effects of the present utility model are as follows

[0015] (1) An adjustable positioning member is adopted, enabling the device to process spline workpieces with different diameters and tooth numbers.

[0016] (2) An adjustable connection assembly is adopted, enabling the device to process workpieces with different lengths.

[0017] (3) The rod improves the connection stability between the support disk and the fixed disk. A spring is used to make the length adjustable. The difference between the ultimate compression length and the normal length of the spring is the ultimate length difference of different workpieces that the rotating mechanism can process.

[0018] (4) The setting of the bottom plate ensures that during the operation of the feeding mechanism, the workpiece will not exceed the positioning range due to relative sliding with the two-jaw cylinder.

[0019] (5) The fixed groove improves the stability when the jaws grip workpieces with different diameters, and the anti-slip pattern further enhances the stability during the gripping process.

[0020] (6) The positioning member is detachably arranged on the connection assembly and can be replaced when facing spline workpieces of different specifications, so as to be applicable to workpieces of different specifications.

[0021] (7) After the jaws gradually clamp, the workpiece slides to the center point position of the two fixed grooves. At this time, the axis of the workpiece coincides with the axis of the positioning member, and the clamping completes the preliminary positioning.

[0022] (8) The positioning teeth are detachable, and the main body of the positioning member is a general cylinder. When it is necessary to position workpieces of different specifications, it is more convenient to replace the positioning teeth than to replace the positioning member, and the production difficulty of the replacement parts is also lower.

[0030] Embodiment 1

[0031] Please refer to Figures 1 to 3 , a kind of angular positioning device described in the present utility model includes a positioning device 1 and a clamping device 2. The positioning device 1 includes a base 11, a rotating mechanism 12 and a feeding mechanism 13. The feeding mechanism 13 is arranged adjacent to the feeding mechanism 13 on the base 11. Through the above technical solution, this layout design ensures the compactness of the device structure and the convenience of operation, and is convenient for realizing the precise positioning and conveying of workpieces.

[0032] The rotating mechanism 12 includes a bracket 121, a positioning member 122, a connecting component 123, a speed reducer 124 and a servo motor 125. A through hole is opened on the bracket 121, and the movable end of the speed reducer 124 passes through the through hole. The connecting component 123 is arranged at the movable end of the speed reducer 124. Through the above technical solution, the design of the rotating mechanism 12 allows the positioning member 122 to perform precise rotational movement, and the design of the through hole makes the driving of the speed reducer 124 and the servo motor 125 more direct and efficient.

[0033] The connecting component 123 includes a fixed disk 1231, a support disk 1232, a rod 1233 and a spring 1234. The fixed disk 1231 is connected to the movable end of the speed reducer 124. A plurality of first holes are opened on the fixed disk 1231, and a plurality of second holes are opened on the support disk 1232. The first holes and the second holes are adapted. The rod 1233 sequentially passes through the first hole, the spring 1234 and the second hole to connect the support disk 1232 to the fixed disk 1231. The two ends of the spring 1234 respectively abut against the support disk 1232 and the fixed disk 1231. Through the above technical solution, the design of the connecting component 123 provides an elastic connection method. The use of the spring 1234 can absorb impacts and vibrations, and improve the stability and durability of the system.

[0034] The positioning member 122 is columnar, with a through hole opened along the columnar axis direction. A detachable positioning tooth 1220 is provided inside the through hole. The positioning member 122 is detachably arranged on the connecting component 123. In the above technical solution, the columnar design of the positioning member 122 and the detachable positioning tooth 1220 provide flexibility and convenient maintainability, facilitating the replacement or adjustment of the positioning tooth 1220 as needed.

[0035] The movable end of the feeding mechanism 13 is fixedly connected to the clamping device 2. The clamping device 2 includes a limiting plate 22 and a two-jaw cylinder 21. The limiting plate 22 includes a bottom plate 221 and a side plate 222 perpendicular to the bottom plate 221. A reinforcing rib is provided between the bottom plate 221 and the side plate 222. The bottom plate 221 is fixedly connected to the movable end of the feeding mechanism 13. The two-jaw cylinder 21 has two symmetrically arranged clamping jaws 211. Symmetric fixing grooves 2110 are opened on the two clamping jaws 211. Anti-slip lines are provided inside the fixing grooves 2110. The two fixing grooves 2110 can form a clamping space. The geometric center point of the clamping space is located on the axis of the positioning member 122. In this way, when the two clamping jaws 211 close, the workpiece will gradually move to the geometric center of the clamping space within the clamping space, that is, it ensures that each workpiece has completed the preliminary positioning process before contacting the positioning member 122.

[0036] In the above technical solution, the design of the clamping device 2 ensures the stability of the workpiece during transportation. The use of the reinforcing rib enhances the strength and rigidity of the structure. The design of the two-jaw cylinder 21 provides symmetric clamping force. The fixing grooves 2110 and the anti-slip lines ensure the stability and safety of the workpiece during the clamping process. By ensuring the alignment of the geometric center of the clamping space with the axis of the positioning member 122, the accuracy and efficiency of workpiece positioning are improved.

[0037] The connecting component 123 is pushed, the spring 1234 is compressed, and the reduction gear 124 drives the connecting component 123 to rotate under the drive of the servo motor 125. The positioning member 122 is rotated while being squeezed by the workpiece. At this time, the workpiece is fixed by the clamping jaws 211 and the anti-slip lines in the fixing grooves 2110. The limiting plate 22 can prevent the workpiece from slipping out of the clamping jaws 211 during the feeding process. In the above technical solution, this design realizes the dynamic positioning of the workpiece. The compression of the spring 1234 and the rotation of the connecting component 123 provide a flexible positioning mechanism. At the same time, the use of the limiting plate 22 prevents the accidental slipping of the workpiece.

[0038] After the positioning member 122 rotates by a certain angle, the positioning teeth 1220 engage with the workpiece, and the two move relative to each other. The spring 1234 is no longer compressed, and the positioning member 122 rebounds to complete the positioning. The connecting component 123 is compressible, changing the connection relationship between the workpiece and the device from a rigid connection to a flexible connection, which can prevent the workpiece from being damaged by the feeding mechanism 13 or the positioning member 122 during the positioning process, adding safety redundancy to the device, with lower maintenance costs and the parts being easy to produce and replace. Through the above technical solution, the flexible connection between the workpiece and the device is realized through the compressibility of the connecting component 123, improving the safety and reliability of the system, while reducing the maintenance cost and production cost.

[0039] Specific working process

[0040] The workpiece is placed between the two jaws 211, and the two-jaw cylinder 21 starts to work. The two jaws 211 start to close, and the workpiece gradually returns to the correct position and moves to the geometric center of the clamping space. The workpiece aligns with the positioning member 122 to complete the preliminary positioning.

[0041] The feeding mechanism 13 and the rotating mechanism 12 start to work. The workpiece approaches the positioning member 122 and contacts the positioning teeth 1220. Since the angles of the splines on the positioning teeth 1220 and the workpiece are different, they cannot engage, and the workpiece and the positioning teeth 1220 cannot move axially relative to each other. Therefore, the workpiece abuts against the positioning teeth 1220 and pushes the positioning member 122 towards the connecting component 123.

[0042] The connecting component 123 is pushed, the spring 1234 is compressed, and the speed reducer 124 drives the connecting component 123 to rotate under the drive of the servo motor 125. The positioning member 122 is driven to rotate while being squeezed by the workpiece, but the workpiece is fixed by the jaws 211 and the anti-slip lines in the fixing grooves 2110.

[0043] After the positioning member 122 rotates by a certain angle, the positioning teeth 1220 engage with the workpiece, and the two make relative axial movements. The spring 1234 is no longer compressed, and the positioning member 122 rebounds. The sensor on the movable end of the feeding mechanism 13 detects the change in force and sends an electrical signal. The servo motor 125 stops working when it receives the electrical signal, and the feeding mechanism 13 retracts, and the workpiece completes the angular positioning.

[0044] The two-jaw cylinder 21 slightly loosens the jaws 211 and waits for the manipulator to clamp.

[0045] The device enters the next working cycle.

[0046] Embodiment 2

[0047] The positioning member 122 is cylindrical, with a hole along its axis, and the positioning teeth 1220 are detachably arranged in the hole through a locking structure.

[0048] The main difference between the first embodiment and the second embodiment is that the positioning teeth 1220 become a detachable structure. In this way, the main body of the positioning member 122 becomes an independent ring-shaped part, and the positioning teeth 1220 essentially become an internal spline bushing, which is convenient for processing and effectively reduces the processing cost. Through the above technical solution, in the second embodiment, the design of the detachable positioning teeth 1220 improves the versatility and maintenance convenience of the positioning member 122, and at the same time reduces the production cost.

[0049] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0050] It should be noted that in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
