Description

Technical Field

[0001] This utility model relates to the field of hydraulic clamp technology, specifically a mobile hydraulic clamp. Background Technology

[0002] Portable hydraulic crimping tools, as efficient and labor-saving hydraulic tools, are widely used in industries such as power, telecommunications, and construction to perform tasks such as wire crimping and metal component compression. Traditional hydraulic crimping tools typically consist of a jaw body, hydraulic cylinder, crimping die, and operating handle. The closing of the jaws and the crimping action are achieved through hydraulic drive. In actual operation, the operator needs to accurately place the workpiece to be crimped (such as cable connectors, metal pipe fittings, etc.) into the crimping die of the hydraulic crimping tool, and then start the hydraulic system to perform the crimping.

[0003] Since hydraulic clamps typically have an open jaw structure and lack effective positioning and clamping devices, they are prone to shifting or slipping when placing workpieces, resulting in unstable crimping quality. This is especially true for crimping operations requiring precision or high strength. Therefore, a mobile hydraulic clamp is needed to improve these issues. Utility Model Content

[0004] The purpose of this invention is to provide a mobile hydraulic clamp to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mobile hydraulic clamp includes a hydraulic clamp body and a positioning and clamping assembly. The hydraulic clamp body has a first groove and a second groove on both the upper and lower surfaces of one side of its opening. Guide rods are provided inside both the first and second grooves. Two positioning and clamping assemblies are provided, each including a rectangular plate and springs. First sliders are provided at the upper and lower ends of the rectangular plate. First sliders are fitted onto the guide rods located inside the two first grooves and two second grooves. Two connecting plates are provided on one side of the rectangular plate, and an arc-shaped clamping plate is provided on one side of each connecting plate. Springs are fitted onto the guide rods located inside the two first grooves and two second grooves. One end of each of the two guide rods is connected to the inner wall of the two first grooves, and one end of each of the other two springs is connected to the inner wall of the two second grooves. The other ends of the four springs are connected to the four first sliders.

[0007] As a preferred embodiment of this utility model, the first slider has a sliding hole, and the first slider slides on the guide rod through the sliding hole. The first slider cooperates with the guide rod through the sliding hole, which converts sliding friction into rolling friction or low-resistance sliding, so that the entire positioning and clamping assembly can move smoothly and stably along the guide rod.

[0008] As a preferred embodiment of this utility model, the openings of the two arc-shaped clamps are opposite to each other. Under the action of spring force, the two opposing arc-shaped clamps can automatically push the cylindrical workpiece to the center of the hydraulic clamp's pressing mold, ensuring accurate pressing position.

[0009] As a preferred embodiment of this utility model, protective plates are provided on the upper and lower parts of one side of the two rectangular plates respectively. The two protective plates on one rectangular plate cover the surfaces of the two first sliding grooves respectively, and the two protective plates on the other rectangular plate cover the surfaces of the two second sliding grooves respectively. As the components move, the protective plates always cover the surfaces of the sliding grooves, effectively preventing foreign objects from entering and ensuring the long-term reliable operation of the mechanism.

[0010] As a preferred embodiment of this utility model, a third slide groove is provided on both sides of the first slide groove and the second slide groove. Two second sliders are provided on one side of the protective plate. The second sliders are slidably engaged inside the third slide groove. The engagement of the second sliders and the third slide groove ensures that the protective plate can move synchronously with the rectangular plate and move smoothly without falling off on its own or interfering with the main movement.

[0011] As a preferred embodiment of this utility model, a placement groove is provided on the inner wall of the hydraulic clamp body, and a crimping mold is placed in the placement groove. This allows the hydraulic clamp to adapt to crimping tasks of different specifications and shapes by changing different crimping molds, thereby improving the versatility of the tool.

[0012] As a preferred embodiment of this utility model, the open end of the hydraulic clamp body is provided with a pin.

[0013] As a preferred embodiment of this utility model, one end of the hydraulic clamp body is provided with a handle, which provides the main gripping point and is the basis for the operator to hold and stabilize the tool. The top of the hydraulic clamp body is provided with a pressure rod, which is the power source of the tool. By manually reciprocating the pressure rod, the hydraulic pump is driven to generate pressure, causing the piston of the hydraulic clamp to move, thereby achieving the closing and pressing of the jaws. One end of the pressure rod and the handle is covered with an anti-slip sleeve, which prevents the hand from slipping when operating with force and reduces the pressure on the hand during long-term operation.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, two opposing arc-shaped clamping plates, under the action of springs, can automatically and synchronously clamp the workpiece (such as a cable connector) to be crimped from both sides. This ensures that the workpiece is always fixed in the center position of the crimping mold, effectively preventing problems such as misalignment and poor contact caused by workpiece slippage or offset during the crimping process, thereby greatly ensuring the consistency and reliability of the crimping operation.

[0016] 2. In this invention, the positioning and clamping assembly is not rigidly fixed, but rather through the sliding engagement of the first slider and the guide rod, with the aid of a spring to provide elastic clamping force. This allows the structure to adapt to workpieces of different diameters within a certain size range, achieving the function of "one-click placement and automatic centering." Operators no longer need to perform tedious manual centering and fixing, greatly simplifying the operation steps, reducing the skill requirements for operators, and improving work efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, and several embodiments of the utility model will be provided. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0024] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0025] A movable hydraulic clamp includes a hydraulic clamp body 1 and a positioning and clamping assembly 7. The hydraulic clamp body 1 has a first sliding groove 101 and a second sliding groove 102 on both the upper and lower surfaces of one side of its opening. The first sliding groove 101 and the second sliding groove 102 define a precise straight path for the movement of the positioning and clamping assembly 7, ensuring that the two arc-shaped clamping plates 708 can only open and close in a direction perpendicular to the clamp jaws, avoiding skeletal movement. Guide rods 103 are provided inside both the first sliding groove 101 and the second sliding groove 102. Two positioning and clamping assemblies 7 are provided, each including a rectangular plate 701 and a spring 704. The rectangular plate 701 is the "skeleton" of the entire assembly, integrating all parts such as the first slider 702, connecting plate 707, arc-shaped clamping plates 708, and protective plate 705 into a single module. The upper and lower ends of the rectangular plate 701 are provided with first sliders 702. The guide rods 103 located inside the two first slide grooves 101 and the two second slide grooves 102 are also fitted with first sliders 702. The two first sliders 702 work together to ensure that the rectangular plate 701 will not twist or jam during movement, and the movement trajectory is always a straight line. Two connecting plates 707 are provided on one side of the rectangular plate 701. The connecting plates 707 transmit the movement of the rectangular plate 701 to the arc-shaped clamping plate 708 and increase the rigidity of the structure. The arc-shaped clamping plate 708 is provided on one side of the two connecting plates 707. The arc-shaped clamping plate 708 is the direct executor of the function. Springs 704 are sleeved on the guide rods 103 located inside the two first slide grooves 101 and the two second slide grooves 102. The springs 704 are the core power source of this component. The spring 704 is in a pre-compressed state, and its elastic force always pushes the two positioning clamping components 7 toward the center line of the hydraulic clamp, thereby automatically clamping the workpiece placed therein. One end of the two guide rods 103 is connected to the inner wall of the two first slide grooves 101 respectively, and one end of the other two springs 704 is connected to the inner wall of the two second slide grooves 102 respectively; the other end of the four springs 704 is connected to the four first sliders 702 respectively.

[0026] In this embodiment, the first slider 702 has a sliding hole 703. The first slider 702 is slidably engaged with the guide rod 103 through the sliding hole 703. The first slider 702 engages with the guide rod 103 through the sliding hole 703, converting sliding friction into rolling friction or low-resistance sliding, so that the entire positioning and clamping assembly 7 can move smoothly and stably along the guide rod 103.

[0027] In this embodiment, the openings of the two arc-shaped clamps 708 are opposite to each other. Under the action of spring force, the two opposing arc-shaped clamps 708 can automatically push the cylindrical workpiece to the center of the hydraulic clamp's pressing mold 6, ensuring accurate pressing position.

[0028] In this embodiment, protective plates 705 are respectively provided on the upper and lower parts of one side of the two rectangular plates 701. The two protective plates 705 on one rectangular plate 701 cover the surfaces of the two first slide grooves 101 respectively, and the two protective plates 705 on the other rectangular plate 701 cover the surfaces of the two second slide grooves 102 respectively. As the component moves, the protective plates 705 always cover the slide groove surfaces, effectively preventing foreign objects from entering and ensuring the long-term reliable operation of the mechanism.

[0029] In this embodiment, a third slide groove 104 is provided on both sides of the first slide groove 101 and the second slide groove 102. Two second sliders 706 are provided on one side of the protective plate 705. The second sliders 706 are slidably engaged inside the third slide groove 104. The engagement of the second sliders 706 and the third slide groove 104 ensures that the protective plate 705 can move synchronously with the rectangular plate 701 and move smoothly without falling off or interfering with the main movement.

[0030] In this embodiment, a placement groove is provided on the inner wall of the hydraulic clamp body 1, and a crimping mold 6 is placed in the placement groove, so that the hydraulic clamp can adapt to crimping tasks of different specifications and shapes by changing different crimping molds 6, thereby improving the versatility of the tool.

[0031] In this embodiment, a pin 5 is provided at the open end of the hydraulic clamp body 1.

[0032] In this embodiment, one end of the hydraulic clamp body 1 is provided with a handle 2, which provides the main gripping point and is the basis for the operator to hold and stabilize the tool. The top of the hydraulic clamp body 1 is provided with a pressure rod 3, which is the power source of the tool. By manually reciprocating the pressure rod 3, the hydraulic pump is driven to generate pressure, causing the piston of the hydraulic clamp to move, thereby achieving the closing and pressing of the jaws. One end of the pressure rod 3 and the handle 2 is covered with an anti-slip sleeve 4. The anti-slip sleeve 4 prevents the hand from slipping when operating with force, and at the same time reduces the pressure on the hand during long-term operation.

[0033] The working process of this utility model is as follows: When the mobile hydraulic clamp and structure designed in this solution are in operation, the operator first moves the two rectangular plates 701 to both sides to compress the spring 704, causing it to contract. At the same time, the rectangular plates 701 slide along the guide rod 103 with the entire assembly. Then, the end of the cable terminal to be crimped is placed in the crimping mold 6. At the same time, the cable is located between the two arc-shaped clamps 708. The compressed spring 704 generates a force, which is transmitted to the first slider 702 and the rectangular plates 701, and then to the connecting plate 707. Finally, it acts on the arc-shaped clamps 708. Driven by the spring force, the two arc-shaped clamps 708 evenly clamp the cable from both sides, thereby ensuring that the end of the cable terminal to be crimped is automatically aligned with the center position of the hydraulic clamp and the crimping mold 6.

[0034] Then, manually operate the pressure lever 3. The hydraulic system starts working and pushes the crimping mold 6 to move through the hydraulic rod, so that it gradually closes to crimp the end of the cable terminal that needs to be crimped.

[0035] The hydraulic clamp body 1 used in this utility model is an existing known electrical device, and all of them can be purchased and used directly on the market. Its structure, circuit and control principle are all existing known technologies. Therefore, the structure, circuit and control principle of the hydraulic clamp body 1 will not be described in detail here.

[0036] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
