Description

Technical Field

[0001] The utility model relates to the field of flow meter production and manufacturing, and more specifically, to a clamping tool. Background Art

[0002] Figure 1 A schematic diagram showing two clamping plates clamped on a flow meter is shown; Figure 1 As shown in the figure, during the processing of the flow meter product, a layer of glue needs to be applied between the flange of the glue barrel and the flange of the metal spray-painted semi-finished product in order to stick the two together. In order to ensure a good bond between the two, two plywood plates need to be used to fix the two and keep them in place for a certain period of time.

[0003] The common practice at present is to use screw rods to connect and fix the two clamps. This operation method has the following defects: first, for different types of flow meter products, each caliber and length are inconsistent, and therefore different types of screw rods need to be prepared, which brings certain management troubles; second, the screw rods are reused frequently and are prone to thread damage, requiring frequent repair and replacement, which adds additional costs. Utility Model Content

[0004] In view of this, the present invention proposes a clamping tool to solve all or part of the above problems.

[0005] According to an embodiment of the present invention, the clamping tool includes a main body, an operating mechanism, an elastic mechanism, a limiting mechanism and a positioning mechanism. The main body includes a first end and a second end of the main body arranged relatively to each other. The operating mechanism and the elastic mechanism are arranged at the first end of the main body. The operating mechanism is connected to the elastic mechanism and is suitable for driving the elastic mechanism to slide along the main body under the action of an external force; the elastic mechanism includes a first end of the elastic mechanism connected to the operating mechanism and a second end of the elastic mechanism away from the first end of the elastic mechanism. The limiting mechanism is arranged at the second end of the main body; the positioning mechanism is movably connected to the limiting mechanism.

[0006] Furthermore, the operating mechanism includes a first end of the operating mechanism and a second end of the operating mechanism, the first end of the operating mechanism can be rotatably mounted on the first end of the main body, the second end of the operating mechanism can be slidably mounted on the first end of the main body, and the first end of the operating mechanism and the second end of the operating mechanism are hingedly connected.

[0007] Furthermore, the elastic mechanism is a spring.

[0008] Furthermore, the second end of the operating mechanism is connected to a first connecting member, and the elastic mechanism also includes a second connecting member arranged at the first end of the elastic mechanism and a third connecting member arranged at the second end of the elastic mechanism, and the first connecting member and the second connecting member are threadedly connected.

[0009] Furthermore, the limiting mechanism is one or more limiting openings.

[0010] Furthermore, when more than one limiting opening is provided, the limiting openings are spaced apart.

[0011] Furthermore, the positioning mechanism is configured as a positioning pin that can be inserted into the limiting opening.

[0012] Furthermore, the clamping fixture is suitable for clamping the first clamping plate and the second clamping plate at the opposite first end and second end of the product to be clamped, respectively.

[0013] Furthermore, the product to be clamped is a flow meter.

[0014] According to an embodiment of the present invention, a clamping fixture is provided with an operating mechanism, an elastic mechanism, and a limiting mechanism in sequence on a main body. When in use, the operating mechanism provided at the first end of the main body pushes the elastic mechanism connected thereto so that the end of the elastic mechanism can abut against the first clamping plate, and the other end cooperates with the positioning mechanism through the limiting mechanism provided at the second end of the main body, thereby clamping the first clamping plate and the second clamping plate between the elastic mechanism and the limiting mechanism. When clamping is not required, the operating mechanism is operated so that the elastic mechanism no longer abuts against the first clamping plate, separating the positioning mechanism from the limiting mechanism, thereby achieving the release of the first clamping plate and the second clamping plate. This clamping fixture can quickly and conveniently complete clamping and can be applied to different types of flow meter products, reducing management and maintenance costs.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail with reference to the following embodiments.

[0031] Figure 2 The figure shows the overall structure of the clamping tool according to one embodiment of the present invention; Figure 3 FIG. 1 shows a schematic diagram of a clamping tool installed on a product to be clamped according to an embodiment of the present invention; FIG. Figure 2 and Figure 3 As shown, the clamping tool includes a main body 1, an operating mechanism 3, an elastic mechanism 5, a limiting mechanism 7 and a positioning mechanism 9. The main body 1 includes a first end and a second end of the main body arranged opposite to each other. The operating mechanism 3 and the elastic mechanism 5 are arranged at the first end of the main body. The operating mechanism 3 is connected to the elastic mechanism 5 and is suitable for driving the elastic mechanism 5 to slide along the main body 1 under the action of an external force; the elastic mechanism 5 includes a first end of the elastic mechanism connected to the operating mechanism 3 and a second end of the elastic mechanism away from the first end of the elastic mechanism. The limiting mechanism 7 is arranged at the second end of the main body; the positioning mechanism 9 is movably connected to the limiting mechanism 7.

[0032] Specifically, the main body 1 can be a long, cylindrical structure made of metal. It includes opposing first and second ends. The operating mechanism 3 and the elastic mechanism 5 are both mounted on the same end of the main body 1, for example, the first end. During operation, the elastic mechanism is adapted to abut against the first clamping plate 101. The positioning mechanism is connected to the limiting mechanism, adapted to clamp the first clamping plate 101 and the second clamping plate (not shown in the drawings) between the limiting mechanism 7 and the elastic mechanism.

[0033] In one implementation, the operating mechanism 3 includes a first end of the operating mechanism and a second end of the operating mechanism, the first end of the operating mechanism is rotatably mounted on the first end of the main body, the second end of the operating mechanism is slidably mounted on the first end of the main body, and the first end of the operating mechanism and the second end of the operating mechanism are hingedly connected.

[0034] Based on this structure, after the second clamping plate is positioned using the limiting mechanism 7 and the positioning mechanism 9, the hinged connection between the first end of the operating mechanism and the second end of the operating mechanism can be driven to rotate the first end around the main body 1 and slide the second end of the operating mechanism along the main body 1, thereby driving the elastic mechanism 5 to move toward the first clamping plate 101, thereby achieving clamping between the elastic mechanism 5 and the first clamping plate 101. Preferably, an operating handle can be provided at the hinged connection between the first end of the operating mechanism and the second end of the operating mechanism to facilitate operation.

[0035] In one implementation, the elastic mechanism 5 includes a spring.

[0036] Based on the above embodiments, in another implementation, a first connecting member 11 is provided at the second end of the operating mechanism, and the elastic mechanism 5 further includes a second connecting member 12 provided at the first end of the elastic mechanism and a third connecting member 13 provided at the second end of the elastic mechanism, and the first connecting member 11 and the second connecting member 12 are threadedly connected.

[0037] Specifically, a first connecting member 11 is provided, which is passed through the outer periphery of the main body 1, and the second end of the operating mechanism is rotatably mounted on one end of the first connecting member 11, and the other end of the first connecting member 11 has a threaded structure; the elastic mechanism 5 also includes a second connecting member 12 arranged at the first end of the elastic mechanism and a third connecting member 13 arranged at the second end of the elastic mechanism, one end of the spring is fixed on the second connecting member 12, and the other end is fixed on the third connecting member 13, and the second connecting member 12 is provided with a threaded structure matching the threaded structure of the first connecting member 11 to connect the second connecting member 12 and the first connecting member 11, and the end of the third connecting member 13 away from the second connecting member 12 is set to a plane, which can be abutted against the end face of the first clamping member when the clamping tool is clamped, so that the clamping effect is better.

[0038] Based on the above structure, the connection between the operating mechanism 3 and the elastic mechanism 5 is achieved, which facilitates the use of the operating mechanism 3 to drive the elastic mechanism 5 to complete the clamping and releasing actions.

[0039] In one implementation, the limiting mechanism 7 is one or more limiting openings.

[0040] Based on the above embodiment, when more than one limiting opening is provided, the limiting openings are spaced apart. In this way, multiple limiting openings can be provided corresponding to the first clamping plate 101 and the second clamping plate at different distances, so as to meet the clamping requirements for the first clamping plate 101 and the second clamping plate at different distances.

[0041] Based on the above embodiment, the positioning mechanism 9 is configured as a positioning pin that can be inserted into the limiting opening. By using a structure in which the positioning pin and the limiting opening cooperate, operation is convenient and cost-effective.

[0042] In one implementation, the clamping fixture is suitable for clamping the first clamping plate 101 and the second clamping plate at the opposite first end and second end of the product 100 to be clamped, respectively.

[0043] In one implementation, the product 100 to be clamped is a flow meter product.

[0044] It can be seen that according to the clamping fixture of the present invention, a main body 1, an operating mechanism 3, an elastic mechanism 5, a limiting mechanism 7 and a positioning mechanism 9 are provided. In the default state, the operating mechanism 3 is operated to make the elastic mechanism 5 in a relaxed state, and the positioning mechanism 9 is not combined with the limiting mechanism 7, so that the fixture as a whole is in an unclamped state. When it is necessary to use the fixture to clamp the first clamp 101 and the second clamp, the main body 1 is inserted into the openings of the first clamp 101 and the second clamp, and the positioning pin is inserted into the limiting opening at the second end of the main body. The operating mechanism 3 is driven at the first end of the main body to tighten the elastic mechanism 5, and then the first clamp 101 and the second clamp are clamped between the third connecting member 13 and the positioning pin; when it is necessary to relax, the operating handle is driven to make the spring return to its natural state, the positioning member is removed, and the main body 1 is taken out from the first clamp 101 and the second clamp.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
