Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining, and in particular to an outwardly extending centering mechanism. Background Technology
[0002] In modern industrial manufacturing and precision machining, accurate positioning and centering technologies are core elements for ensuring product quality and production efficiency, leading to the development of outward-extending centering mechanisms. In traditional manufacturing, workpiece positioning often relies on manual measurement and simple fixtures, resulting in low efficiency and poor accuracy, making it difficult to meet the demands of large-scale, high-precision production. For example, some mechanisms use traditional gear drives, which wear down over time, causing changes in the transmission ratio and resulting in deviations in the centering position. Furthermore, their measurement feedback systems lack accuracy, and the sensors have low sensitivity, failing to capture minute changes during the centering process in a timely and accurate manner, making it difficult to achieve high-precision centering and positioning, and thus unable to meet the requirements of high-precision machining. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an outwardly extending centering mechanism. By rotating the handle, the transmission component is driven to slide along the base. The transmission component simultaneously drives the two centering blocks to contract inward or expand outward, thereby achieving the centering and positioning effect.
[0004] The objective of this utility model is achieved through the following solution:
[0005] This utility model discloses an outwardly extending centering mechanism, comprising:
[0006] Base;
[0007] A rotating handle is rotatably mounted on the base;
[0008] The transmission component is slidably mounted on the base, and one end of it can be rotatably connected to the rotary handle, converting the rotational motion of the rotary handle into linear motion;
[0009] Two center blocks are slidably mounted on the base and cooperate with the other end of the transmission assembly to achieve synchronous inward or outward movement.
[0010] When the rotary handle is rotated to the first position, the transmission assembly causes the two dividing blocks to retract inward to facilitate loading the product; when the rotary handle is rotated to the second position, the transmission assembly causes the two dividing blocks to expand outward to secure the product.
[0011] Furthermore, the outwardly extending centering mechanism also includes a bracket, which has a first groove, and the base is movably disposed in the first groove to provide support for the base.
[0012] Furthermore, a positioning pin is movably provided on the bracket, and a second groove is provided on the base. The positioning pin is inserted into the second groove to position the base on the bracket.
[0013] Furthermore, the base includes a first seat body, which has a through hole for accommodating the dividing block, and the dividing block moves inward or expands outward within the through hole.
[0014] Furthermore, the base includes a second seat body, which has a hollow groove for accommodating the transmission assembly, and the transmission assembly moves linearly within the hollow groove.
[0015] Furthermore, the base includes a third body, which is provided with a clamping part for fixing the rotating handle, and the rotating handle rotates within the clamping part.
[0016] Furthermore, the transmission component is in the shape of an inverted Y, and the center block is provided with a slanted groove. The other end of the transmission component is inserted into the slanted groove of the center block to achieve motion engagement.
[0017] Furthermore, the threaded post on the rotary handle is connected to the threaded hole of the transmission assembly via a thread.
[0018] Furthermore, the outwardly extending centering mechanism also includes a push-pull handle, which is disposed on the base on the other side away from the centering block, and is used to drive the first seat to move away from the product, thereby realizing the separation of the outwardly extending centering mechanism from the product.
[0019] Furthermore, a stop member is provided at one end of the push-pull handle that connects to the base, and the stop member is used to limit the pushing stroke of the push-pull handle.
[0020] The advantage of this utility model is that, through the mechanical linkage design of the rotating handle and the transmission component, the rotation operation is directly converted into the synchronous linear motion of the transmission component. The transmission component and the inclined groove of the center block form a wedge-shaped transmission, which converts the torque of the rotating handle into a synchronous expansion force. The push-pull handle is equipped with a stop component, which can not only realize the safe separation of the mechanism and the product, but also limit the stroke to prevent the base from falling out and avoid the risk of collision.

[0029] Please see Figures 1-4 This utility model discloses an outwardly extending centering mechanism, comprising:
[0030] Base 10;
[0031] A rotating handle 20 is rotatably mounted on the base 10;
[0032] The transmission component 30 is slidably disposed on the base 10, and one end of it can be rotatably connected to the rotating handle 20, and converts the rotational motion of the rotating handle 20 into linear motion;
[0033] Two centering blocks 40 are slidably disposed on the base 10 and cooperate with the other end of the transmission assembly 30 to achieve synchronous inward or outward expansion. When the rotating handle 20 is rotated to the first position, the transmission assembly 30 drives the two centering blocks 40 to retract inward to facilitate product loading; when the rotating handle 20 is rotated to the second position, the transmission assembly 30 drives the two centering blocks 40 to expand outward to secure the product.
[0034] Please see Figure 2 The outwardly extending centering mechanism further includes a support 50, which has a first groove 51. The base 10 is movably disposed within the first groove 51 to provide support for the base 10. This movable arrangement allows the base 10 to move flexibly within a certain range, while being constrained by the first groove 51, preventing it from swaying or deviating from its predetermined position. The support 50 provides solid support to the base 10 through the first groove 51, and during the operation of the centering mechanism, it can withstand various forces generated by the base 10 and other components mounted on it, ensuring the stability of the base 10.
[0035] A positioning pin 52 is movably disposed on the bracket 50, and a second groove 11 is formed on the base 10. The positioning pin 52 is inserted into the second groove 11 to position the base 10 on the bracket 50. When the outward extending centering mechanism is working, the base 10 moves within the first groove 51 of the bracket 50 to achieve the outward extending centering function. When the base 10 moves to the predetermined position, the operator inserts the positioning pin 52 into the corresponding position on the bracket 50, ensuring that its head is accurately inserted into the second groove 11 on the base 10. At this time, the positioning pin 52 and the second groove 11 are tightly engaged, constraining the base 10 and firmly positioning it on the bracket 50. This ensures that the base 10 and other connected components maintain a stable position during operation, thereby achieving precise centering operation.
[0036] Please see Figures 1-2The base 10 includes a first seat 12, which has a through hole 121 for accommodating the centering block 40. The centering block 40 moves inward or outward within the through hole 121. When the outward-extending centering mechanism is in operation, the object to be centered is first placed in a suitable position, placing it within the effective range of the centering block 40. Then, the drive device is activated, driving the centering block 40 to move inward within the through hole 121 of the first seat 12. During the movement, the centering block 40 gradually contacts the object and, through its special shape and movement, squeezes the object towards the center, achieving precise positioning and centering. After the centering operation is completed, the drive device reverses its action, causing the centering block 40 to expand outward and separate from the object, facilitating subsequent operations or object removal. The base 10 also includes a second seat 13, which has a hollow groove 131 for accommodating the transmission assembly 30. The transmission assembly 30 moves linearly within the hollow groove 131. When the outward-extending centering mechanism is working, rotating the rotary handle 20 transmits power to the transmission assembly 30. The transmission assembly 30 moves linearly within the hollow groove 131 of the second base 13, simultaneously driving the connected centering block 40 to move together. The centering block 40 moves inward or outward according to the direction and stroke of the transmission assembly 30, precisely positioning and centering the product. After the centering operation is completed, the rotary handle 20 reverses its movement, and the transmission assembly 30 drives the centering block 40 back to its initial position, preparing for the next centering operation. The base 10 includes a third base 14, which has a clamping part 141 for fixing the rotary handle 20, within which the rotary handle 20 rotates. When the outward-extending centering mechanism is working, the operator manually rotates the rotary handle 20 fixed on the third base 14 according to the centering requirements of the workpiece. The rotating handle 20 rotates around its axis within the clamping part 141, and transmits the rotational motion to the dividing block 40 through the transmission component 30 connected thereto, causing the dividing block 40 to move inward or outward.
[0037] Please see Figures 3-4The transmission assembly 30 is in the shape of an inverted Y. The centering block 40 has a groove 41, and the other end of the transmission assembly 30 is inserted into the groove 41 of the centering block 40 to achieve motion engagement. The inverted Y-shaped transmission assembly 30 consists of a main trunk and two branches. The main trunk is connected to the rotating handle 20 and receives power from it. The two branches respectively engage with the centering block 40, transmitting motion to it. The centering block 40 has a groove 41, the shape and size of which match the branches of the transmission assembly 30. When the rotating handle 20 is activated, driving the main trunk of the transmission assembly 30, the two branches simultaneously move due to the inverted Y shape of the transmission assembly 30. Because the branches are inserted into the grooves 41 of the centering block 40, the movement of the branches forces the centering block 40 to move in a specific direction. Specifically, when the main body of the transmission assembly 30 moves in a straight line, the branch, constrained by the inclined groove 41, decomposes the motion into a component force along the direction of the inclined groove 41 and a component force perpendicular to the direction of the inclined groove 41. The component force perpendicular to the direction of the inclined groove 41 will push the centering block 40 to move inward or outward, thereby realizing the centering operation.
[0038] The threaded post 21 of the rotary handle 20 is threadedly connected to the threaded hole 31 of the transmission assembly 30. When the operator rotates the rotary handle 20, the threaded post 21 rotates accordingly. Since the threaded post 21 is threadedly connected to the threaded hole 31 of the transmission assembly 30, according to the transmission principle of threads, the rotational motion of the threaded post 21 is converted into linear motion along the axis of the threaded hole 31. This motion is further transmitted to the centering block 40 through the transmission assembly 30, causing the centering block 40 to produce corresponding centering actions, such as moving inward or expanding outward, thereby realizing the centering operation of the workpiece.
[0039] Please see Figure 2The outwardly extending centering mechanism also includes a push-pull handle 60, which is disposed on the base 10 on the side away from the centering block 40. The push-pull handle 60 is used to move the first seat 12 away from the product, thus separating the outwardly extending centering mechanism from the product. When it is necessary to separate the outwardly extending centering mechanism from the product, the operator grasps the push-pull handle 60 and applies a pulling force. Through the connection and transmission between the push-pull handle 60 and the first seat 12, this force is transmitted to the first seat 12, causing it to move accordingly. The first seat 12 will move along the direction of movement of the push-pull handle 60 and separate from the product. A stop member 61 is provided at one end of the push-pull handle 60 connected to the base 10. The stop member 61 is used to limit the pushing stroke of the push-pull handle 60. When the operator pushes the push-pull handle 60, the push-pull handle 60 drives the stop member 61 to move together towards the base 10. As the push-pull handle 60 is pushed, the stop member 61 gradually approaches the bracket 50. When the push-pull handle 60 reaches its predetermined maximum push stroke, the stop member 61 contacts the bracket 50. At this point, the stop member 61 is blocked and cannot continue to move forward, thus limiting the further push of the push-pull handle 60 and restricting its push stroke. This restriction ensures that the first seat 12 stops after moving to the appropriate position under the action of the push-pull handle 60, guaranteeing the accuracy and stability of the separation operation between the outward extension centering mechanism and the product.
[0040] The outwardly extending centering mechanism provided by this utility model, through the mechanical linkage design of the rotating handle 20 and the transmission component 30, directly converts the rotation operation into the synchronous linear motion of the transmission component 30. The transmission component 30 and the inclined groove 41 of the centering block 40 form a wedge-shaped transmission, which converts the torque of the rotating handle 20 into a synchronous expansion force. The push-pull handle 60 is equipped with a stop part 61, which can not only realize the safe separation of the mechanism and the product, but also limit the stroke to prevent the base 10 from falling out and avoid the risk of collision.
[0041] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
