Description

Technical Field

[0001] This utility model belongs to the field of machining fixture technology, and in particular relates to a dome fixture for machining cemented carbide. Background Technology

[0002] Hard alloy is an alloy material made from hard compounds of refractory metals and binder metals through powder metallurgy. It has the characteristics of high hardness, good toughness, high strength and toughness, and heat and corrosion resistance. Based on these characteristics, it is often used to make cutting tools or drill bits and other machining tools. Due to its wear resistance, it can also be used as bearings, guide rails and nozzles, playing an important role in industries such as machinery, metallurgy, petroleum, chemical industry and building materials.

[0003] In the process of machining cemented carbide, it is sometimes necessary to stand the workpiece upright. When machining workpieces that are arcs, rings, or arches, traditional fixed fixtures generally use single-point or double-point clamping, which results in small contact with the arc and unstable clamping due to the large diameter of the arc. This can affect the machining process. To solve the above problems, there is an urgent need for an arched fixture for cemented carbide machining. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of unstable clamping when machining workpieces with arcs or other curved surfaces due to the small contact area of ​​traditional clamps. Therefore, a dome clamp for machining cemented carbide is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dome fixture for machining cemented carbide, comprising a base plate, a support rod mounted on the top surface of the base plate, a placement seat mounted on the top of the support rod, and connecting plates mounted on both sides of the placement seat; an adjustment assembly mounted on one end of the connecting plates; and a clamping assembly mounted inside the adjustment assembly, wherein the clamping assembly and the adjustment assembly are slidably connected. The adjusting component includes a bidirectional threaded rod, the outer wall of which is threaded with a threaded sleeve, and rotating shafts are installed on both sides of the threaded sleeve. A mounting bracket is rotatably installed on the outer wall of the rotating shaft.

[0006] As a further description of the above technical solution: The outer wall of the bidirectional threaded rod is fitted with a nut, and the inner side of the mounting bracket is provided with a slot.

[0007] As a further description of the above technical solution: The mounting bracket is rotatably connected to the connecting posts on both sides of the connecting plate through the through holes opened inside, and two mounting brackets are symmetrically arranged.

[0008] As a further description of the above technical solution: The clamping assembly includes a mounting base, with limit blocks installed on both sides of the mounting base, a fixing plate installed on the top of the mounting base, and a sliding plate slidably installed in a groove opened on the top surface of the mounting base.

[0009] As a further description of the above technical solution: A spring is installed on one side of the sliding plate, and an insert is installed on the other side of the sliding plate. The mounting base is threadedly connected to a threaded rod through a threaded hole on one side.

[0010] As a further description of the above technical solution: A push plate is rotatably mounted on one end of the threaded rod. The push plate is slidably connected to the mounting base through a groove on the top surface of the mounting base. The limiting block is slidably connected to the mounting frame through a groove inside the mounting frame.

[0011] As a further description of the above technical solution: The insert block is slidably connected to the mounting frame through a slot on one side of the mounting frame, and multiple slots are provided on one side of the mounting frame.

[0012] As a further description of the above technical solution: The fixed plate has a groove on one side that corresponds to the sliding plate, and the other end of the spring is fixedly connected to the mounting base, and the spring is in a stretched state.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, when clamping a circular arc-shaped or arched workpiece, it can be placed on the top surface of the placement seat, and the mounting frame can be rotated by rotating the bidirectional threaded rod, thereby bringing the mounting seat closer to the workpiece. Then, the workpiece is clamped by the push plate and the fixing plate. At the same time, the support of the placement seat for the workpiece further ensures the stability of the workpiece clamping. Since the mounting frame can rotate, it can clamp clamps with different curvatures.

[0014] 2. In this utility model, when clamping the workpiece, it can be moved to a suitable position by sliding the mounting base, thereby ensuring that the push plate and the fixing plate can stably clamp the workpiece. At the same time, during the clamping process, the workpiece can push the sliding plate to move and allow the insert block to be inserted into the slot on one side of the mounting frame, thereby fixing the mounting base and the mounting frame, thus avoiding the impact of the sliding of the mounting base on the stability of workpiece clamping during the processing.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] In its specific implementation, such as Figures 1-4 This utility model provides a technical solution: a dome fixture for machining cemented carbide, including a base plate 1, a support rod 2 installed on the top surface of the base plate 1, a placement seat 3 installed at the top of the support rod 2, and connecting plates 4 installed on both sides of the placement seat 3; an adjustment component 5, which is installed at one end of the connecting plate 4; and a clamping component 6, which is installed inside the adjustment component 5 and is slidably connected to the adjustment component 5. The adjusting component 5 includes a bidirectional threaded rod 55, with a threaded sleeve 53 threadedly connected to the outer wall of the bidirectional threaded rod 55. A rotating shaft 54 ​​is installed on both sides of the threaded sleeve 53. A mounting bracket 52 is rotatably installed on the outer wall of the rotating shaft 54. A nut 56 is installed on the outer wall of the bidirectional threaded rod 55. A slot 51 is opened on the inner side of the mounting bracket 52. The mounting bracket 52 is rotatably connected to the connecting posts on both sides of the connecting plate 4 through the through hole opened inside. Two mounting brackets 52 are symmetrically arranged.

[0022] Specifically, when clamping an arc-shaped workpiece, the double-threaded rod 55 can be rotated by rotating the nut 56, which in turn moves the threaded sleeve 53 and rotates the mounting bracket 52, allowing the mounting bracket 52 to gradually move closer to the workpiece, so that the mounting base 67 comes into contact with the workpiece, thereby fixing the workpiece through the push plate 65 and the fixing plate 61. like Figure 3 As shown, the clamping assembly 6 includes a mounting base 67, with limit blocks 68 installed on both sides of the mounting base 67, a fixing plate 61 installed on the top of the mounting base 67, a sliding plate 63 slidably installed in a groove opened on the top surface of the mounting base 67, a spring 64 installed on one side of the sliding plate 63, and an insert block 62 installed on the other side of the sliding plate 63. A threaded rod 66 is threadedly connected to the mounting base 67 through a threaded hole opened on one side. A push plate 65 is rotatably installed at one end of the threaded rod 66. The push plate 65 is slidably connected to the mounting base 67 through a groove opened on the top surface of the mounting base 67. The limit blocks 68 are slidably connected to the mounting frame 52 through a groove opened in the mounting frame 52. The insert block 62 is slidably connected to the mounting frame 52 through a groove opened on one side of the mounting frame 52. The mounting frame 52 has multiple grooves on one side. The fixing plate 61 has a groove on one side corresponding to the sliding plate 63. The other end of the spring 64 is fixedly connected to the mounting base 67 and the spring 64 is in a stretched state. Specifically, during the process of the mounting base 67 approaching the workpiece, the mounting base 67 can be slid to a suitable position. After the mounting base 67 contacts the workpiece, the push plate 65 is moved by rotating the threaded rod 66, thereby pushing the workpiece closer to the fixed plate 61 and causing the sliding plate 63 to slide towards the fixed plate 61. At the same time, the movement of the sliding plate 63 allows the insert block 62 to be inserted into the slot 51 opened on one side of the mounting bracket 52, thereby fixing the mounting base 67 and the mounting bracket 52.

[0023] Working principle: When clamping an arc-shaped workpiece, the workpiece is placed above the placement seat 3. Then, by rotating the nut 56, the bidirectional threaded rod 55 is rotated, which moves the threaded sleeve 53 and causes the mounting bracket 52 to rotate, allowing the mounting bracket 52 to gradually approach the workpiece. Then, the sliding mounting seat 67 slides the workpiece to a suitable position. After the mounting seat 67 contacts the workpiece, the threaded rod 66 is rotated to move the push plate 65, pushing the workpiece closer to the fixed plate 61. This causes the sliding plate 63 to slide towards the fixed plate 61. At the same time, the movement of the sliding plate 63 allows the insert block 62 to be inserted into the slot 51 opened on one side of the mounting bracket 52.
