Description

Technical Field

[0001] This utility model relates to the field of metal processing auxiliary equipment technology, specifically a clamp for milling the head of a bolt cutter. Background Technology

[0002] In the field of bolt cutter manufacturing, the clamp head, as the core force-bearing component, is often irregularly shaped and needs to be adapted to different specifications of bolt cutter products. During milling, the requirements for the fixture's "irregular fit, multi-specification compatibility, and clamping stability" are extremely high.

[0003] A search revealed existing technology (application number: CN201822012728.2), which describes a "clamp for milling the head of a bolt cutter". This utility model has a compact structure, is easy to operate, and occupies little space during use. It can quickly and accurately clamp and position the head of a bolt cutter, facilitating the milling process of the head. The positioning stud facilitates the lifting and adjustment of the anti-slip base. The hydraulic telescopic rod allows for quick clamping and positioning of the head, and the motor facilitates the rotation adjustment of the head.

[0004] However, while existing technologies offer compact structures, convenient operation, and minimal space requirements, enabling quick and precise clamping and positioning of the pliers' heads for milling, and facilitating the adjustment of the anti-slip base with positioning studs, and allowing for rapid clamping and positioning of the pliers via hydraulic telescopic rods, and facilitating the rotation adjustment of the pliers' heads, they still have some shortcomings: existing clamps mostly use fixed flat pressure plates or single arc-shaped pressure blocks, which cannot conform to the irregular surface of the pliers' heads, easily leading to problems such as "partial suspension" or "excessive compression" during clamping; although some clamps attempt to adapt to irregular structures by replacing the pressure blocks, each replacement requires disassembly and reassembly, and a gap still exists between the pressure block and the pliers' head surface, making the material prone to displacement due to vibration during milling, resulting in dimensional deviations in the machining process. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a clamp for milling the head of a pliers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a clamp for milling the head of a pliers, comprising: a main body assembly, set on the ground; a clamping assembly, set on the main body assembly; and two sets of clamping assemblies, set on the main body assembly; wherein the clamping assembly comprises: a rotating block, rotatably connected to the clamping assembly, for clamping irregularly shaped materials.

[0007] As a further description of the above technical solution:

[0008] The clamping assembly further includes: a cylinder, which is mounted on the main body assembly; a sliding block, which is fixedly connected to the output end of the cylinder and slidably connected to the main body assembly; and two sets of clamping blocks, which are mounted on the rotating block.

[0009] As a further description of the above technical solution:

[0010] The main components include: a housing, which is set on the ground; and a groove, which is formed on the housing.

[0011] As a further description of the above technical solution:

[0012] The clamping assembly includes: a slider slidably connected to the housing; a clamping block slidably connected to the housing; and two sets of threaded rods threadedly connected to the slider.

[0013] As a further description of the above technical solution:

[0014] The outer shell is provided with a guide groove, and the sliding block is slidably connected inside the guide groove.

[0015] As a further description of the above technical solution:

[0016] The clamping block is slidably connected to the slide groove and is used to adjust the position of the clamped material.

[0017] As a further description of the above technical solution:

[0018] The clamping block has a sliding groove, and the threaded rod is slidably connected inside the sliding groove.

[0019] This utility model has the following beneficial effects:

[0020] The clamping assembly, through the cooperation of the rotating block and two sets of clamping blocks, allows the rotating block to adapt to the irregular surface of the clamping head, thereby increasing the contact area between the clamping block and the clamping head and avoiding the problem of "partial suspension". Moreover, it can adapt to different irregular structures without replacing the clamping blocks, saving changeover time compared to existing fixtures. During milling, the material vibration displacement is controlled, the machining dimensional deviation is reduced, the finished product qualification rate is improved, and the milling accuracy is guaranteed.

[0030] Example 1:

[0031] like Figures 1 to 4As shown, this embodiment provides a clamp for milling the head of a pliers, including: a main body assembly 1, which is set on the ground; a clamping assembly 2, which is set on the main body assembly 1; and two sets of clamping assemblies 3, which are set on the main body assembly 1. The clamping assembly 2 includes: a rotating block 23, which is rotatably connected to the clamping assembly 2 and is used to clamp irregularly shaped materials.

[0032] In this embodiment, the clamping component and the clamping component constitute a clamp for milling the head of a bolt cutter according to this application.

[0033] It should also be noted that the clamp for milling the head of a bolt cutter in this application can be a high-precision bolt cutter head milling clamp, a mass production bolt cutter head milling clamp, or a multi-specification small-batch bolt cutter head milling clamp, etc. Figure 1 In this embodiment, a high-precision clamping fixture for milling clamp heads is used as an example for description. Of course, other types of clamping fixtures for milling clamp heads can also adopt similar structures, which will not be described in detail below.

[0034] Understandable, Figure 1 This illustration only schematically shows some components of a clamping tool for milling with a pliers head. The actual shape, size, position, and construction of these components are not subject to change. Figure 1 Due to limitations, a clamp for milling the head of a bolt cutter can also include, compared to... Figure 1 More or fewer parts.

[0035] It should also be understood that cylinder 21 was purchased from the market and is common knowledge in this field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0036] In addition, in this embodiment, the main body component 1 provides a fixture mounting base, the clamping component 2 clamps the material from above, the two sets of clamping components 3 clamp the material from both sides, and the rotating block 23 rotates and fits the material according to its shape.

[0037] Specifically, the clamping assembly 2 also includes: a cylinder 21, which is mounted on the main body assembly 1; a sliding block 22, which is fixedly connected to the output end of the cylinder 21 and slidably connected to the main body assembly 1; and two sets of clamping blocks 24, which are mounted on the rotating block 23.

[0038] In this embodiment, the piston rod of cylinder 21 extends and retracts, causing sliding block 22 to slide up and down along the guide groove. Sliding block 22 causes rotating block 23 and pressing block 24 to move down, and pressing block 24 fits against the surface of the pliers head.

[0039] Specifically, the main component 1 includes: a housing 11, which is set on the ground; and a groove 12, which is formed on the housing 11.

[0040] In this embodiment, the housing 11 carries the components, and the slide 12 provides guidance for the movement of the clamping component 3.

[0041] Specifically, the clamping assembly 3 includes: a slider 31, which is slidably connected to the housing 11; a clamping block 32, which is slidably connected to the housing 11; and two sets of threaded rods 33, which are threadedly connected to the slider 31.

[0042] In this embodiment, the slider 31 is pushed to move along the outer shell 11 to be close to the material, and the threaded rod 33 is rotated to push the clamping block 32 to slide towards the material, and the clamping block 32 abuts against both sides of the clamping head of the heavy-duty pliers.

[0043] Specifically, a guide groove is provided on the outer casing 11, and the sliding block 22 is slidably connected inside the guide groove.

[0044] With this configuration, the guide groove restricts the sliding trajectory of the sliding block 22, ensuring that the sliding block 22 drives the pressing component 2 to move up and down precisely.

[0045] Specifically, the clamping block 32 is slidably connected to the slide groove 12 and is used to adjust the position of the clamped material.

[0046] The clamping block 32 slides along the slide groove 12 to adjust the distance between the two sets of clamping blocks 32, adapting to the pliers heads of different lengths.

[0047] Specifically, the clamping block 32 has a groove 12, and the threaded rod 33 is slidably connected inside the groove 12.

[0048] In this embodiment, the threaded rod 33 slides up and down along the groove 12 of the clamping block 32 to adjust the contact position between the threaded rod 33 and the clamping block 32, adapting to the pliers heads of different heights.

[0049] In actual use, the operator first opens a guide groove on the outer shell 11, and slides the block 22 inside the guide groove. According to the width of the material, the sliding slider 31 drives the clamping block 32 to slide and clamp the material on both sides. The clamping block 32 is slidably connected to the slide groove 12 to adjust the position of clamping the material. When it slides to the designated position, the threaded rod 33 is rotated to clamp the slider 31 and the clamping block 32 on the outer shell 11. The clamping block 32 has a slide groove 12, and the threaded rod 33 is slidably connected inside the slide groove 12. The cylinder 21 is turned on to drive the sliding block 22 to slide and connect to the outer shell 11, so that the rotating block 23 rotates around the sliding block 22, driving the pressing block 24 to press against the material.

[0050] The cylinder 21 is electrically connected to the controller, which is electrically connected to an external power source. The controller facilitates the power supply control of the electrical equipment, ensuring that the equipment can be powered on when needed, thus avoiding the situation where power cannot be supplied when power is required.

[0051] It should be noted that the controller can be a conventional known device that is controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific embodiments of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
