Description

Technical Field

[0001] This utility model relates to the field of instrument manufacturing and processing, specifically a clamping device used in the manufacturing and processing of electricity meters. Background Technology

[0002] In the field of instrument machining, fixtures play a crucial role. They are used to fix, position, and clamp instruments during machining, ensuring they maintain the correct position and orientation and preventing displacement or vibration under external forces such as cutting forces and gravity. However, traditional instrument machining fixtures mostly rely on manual adjustment of the chuck spacing to clamp the instruments. This operation is not only labor-intensive, but also difficult to guarantee consistency in clamping due to variations in human operation. This can easily lead to clamping that is too loose or too tight, thus affecting machining accuracy and increasing the risk of human error.

[0003] Furthermore, existing fixtures present a significant problem when handling instruments with special shapes: due to their irregular geometry or internal structure, the center of gravity of these instruments is often not at their geometric center. If the clamping points are not accurately positioned and their center of gravity is not properly held, the instruments are prone to wobble or vibration during machining. This instability severely affects machining quality and accuracy, resulting in instruments that do not meet requirements, such as substandard surface roughness or large dimensional deviations. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for the production and processing of electricity meters, which aims to solve the problems in the prior art such as the reliance on manual adjustment of clamps, poor clamping consistency, low degree of automation, and difficulty in stably clamping instruments whose center of gravity deviates from the geometric center.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A clamping device for the production and processing of electricity meters includes a mounting base and a clamping part, wherein the clamping part is rotatable along the axis of the mounting base.

[0006] Two clamping blocks are symmetrically arranged on the clamping part, and a hinge shaft is provided in the middle of the clamping block. The clamping block is rotatably mounted on the clamping part through the hinge shaft. The clamping part is also slidably provided with a push block, which can move along the axial direction of the mounting base. The push block includes a top head that abuts against the instrument.

[0007] The clamping part is also provided with a linkage plate, which has a first sliding groove and a second sliding groove. The clamping block is provided with a guide protrusion that slides in the first sliding groove, and the pushing block is provided with a driving protrusion that slides in the second sliding groove. By axially moving the pushing block, its driving protrusion drives the linkage plate to translate. The linkage plate, in turn, through the cooperation of the first sliding groove and the guide protrusion, drives the two clamping blocks to open or close synchronously, realizing the automatic clamping and release of the instrument.

[0008] Furthermore, the clamping block is also equipped with an adjustment component for fine-tuning the clamping point to adapt to instruments of different shapes or with different center of gravity offsets.

[0009] As a preferred embodiment, the adjusting assembly includes a locking block fixed to the clamping block, the locking block having two symmetrically arranged toothed portions. An extension arm is also slidably disposed on the locking block, the inner side of the extension arm having a toothed region corresponding to the toothed portions. By adjusting the extension length of the extension arm and locking it using the engagement of the toothed portions and the toothed region, the actual clamping point position can be changed.

[0010] To ensure the reliability of the locking, a spring is provided between the two toothed portions to press the toothed portions against the toothed area of ​​the extension arm.

[0011] In order to enable the device to rotate and to supply power to the electrical components on the clamping part, a conductive slip ring is provided between the mounting base and the clamping part.

[0012] To improve automation, a linear motor is installed inside the clamping part, and the output end of the linear motor is fixedly connected to the push block to drive the push block to automatically clamp and release. A rotary motor is installed inside the mounting base, and the output end of the rotary motor is fixedly connected to the clamping part to drive the entire clamping part to rotate.

[0013] Compared with the prior art, the present invention has the following significant advantages: 1. High degree of automation and good clamping consistency: The linear motor drives the push block, and the linkage mechanism synchronously controls the opening and closing of the two clamping blocks, realizing automatic clamping and release of the instrument. This mechanical linkage method replaces manual adjustment, ensuring the repeatability of clamping force and the consistency of position each time, effectively avoiding the problem of decreased processing accuracy caused by clamping too loosely or too tightly.

[0014] 2. High adaptability and stable clamping of irregular instruments: The adjustment components inside the clamping blocks allow operators to independently fine-tune the position of each clamping point. For instruments with special shapes whose center of gravity deviates from the geometric center, the clamping point can be precisely set at its center of gravity position through this adjustment component, forming a stable three-point clamping (two clamping blocks and a push block), thereby effectively preventing the instrument from swaying or vibrating during rotational machining, significantly improving machining quality and accuracy.

[0018] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0019] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1 like Figure 1-4 As shown, this utility model provides a clamping device for the production and processing of electricity meters. The device includes a fixed mounting base 1 and a clamping part 2 that can rotate about the axis of the mounting base 1.

[0021] The clamping part 2 is provided with two symmetrical clamping blocks 3 and an axially movable push block 5. The tops 6 of the two clamping blocks 3 and the push block 5 form three contact points, which stably clamp the instrument in the middle. Each clamping block 3 is rotatably mounted on the clamping part 2 through the central hinge shaft 4, so that it can open or close like jaws.

[0022] To achieve synchronized movement of the clamping blocks 3, a linkage plate 7 is provided inside the clamping part 2. The linkage plate 7 has two sliding grooves: a first sliding groove 8 and a second sliding groove 9. Each clamping block 3 is provided with a guide protrusion 10, which slides within the first sliding groove 8. At the same time, the push block 5 is provided with a drive protrusion 11, which slides within the second sliding groove 9.

[0023] The workflow is as follows: The rotary motor inside the mounting base 1 drives the entire clamping part 2 to rotate. The linear motor 19 inside the clamping part 2 drives the push block 5 to move forward along the axis. When the push block 5 moves forward, its top 6 first abuts against one surface of the instrument. As the push block 5 continues to move forward, the drive protrusion 11 on it slides in the second slide groove 9, causing the linkage plate 7 to translate as a whole. The translation of the linkage plate 7 causes the first slide groove 8 to move relative to the hinge axis 4 of the clamping block 3, thereby forcing the guide protrusion 10 on the clamping block 3 to slide along the first slide groove 8, so that the two clamping blocks 3 rotate inward synchronously around their respective hinge axes 4, and finally clamp the instrument from both sides. At this time, the instrument is firmly fixed by the two clamping blocks 3 and the top 6 of the push block 5 at three points. When the linear motor 19 moves in the opposite direction, the push block 5 retracts, and through the linkage mechanism, drives the two clamping blocks 3 to open synchronously, releasing the instrument.

[0024] Adjustments for irregularly shaped instruments: When machining instruments with an off-center center of gravity, the adjustment assembly 12 of this device comes into play. Each clamping block 3 contains an adjustment assembly 12. This assembly includes a locking block 13 fixed to the clamping block 3 and an extension arm 15 that can slide on the locking block 13. The locking block 13 has two elastic arms with toothed portions 14, and the extension arm 15 has matching toothed areas 16. During adjustment, the operator can pull or push the extension arm 15 to change its length extending out of the clamping block 3. Because of the opening spring 17 between the two toothed portions 14, they engage tightly with the toothed areas 16 of the extension arm 15, thereby locking the extension arm 15 in the new position. By adjusting the lengths of the extension arms 15 of the two clamping blocks 3, the actual operating position of the three-point clamping can be changed, ensuring it acts precisely on the center of gravity of the instrument and guaranteeing the smoothness of subsequent rotary machining.

[0025] In addition, in order to continue supplying power to the linear motor 19 inside the clamping part 2 while it is rotating, a conductive slip ring 18 is provided between the mounting base 1 and the clamping part 2, which solves the problem of power and signal transmission between the rotating body and the stationary body.

[0026] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
