Description

Technical Field

[0001] The utility model relates to the technical field of carbide blade production, in particular to a clamp for clamping a fast-feed blade. Background Art

[0002] Carbide blades are produced through powder metallurgy process. In the powder forming stage, semi-finished blades are brittle because they are not sintered. Picking and transferring are all done by manual clamping. The big problem is that manual picking and transferring will cause product pinching and collision. Once such defects occur, the blades can only be scrapped. Under the microscope, they are all gaps. The processing environment of cemented carbide blades requires that their surface is smooth and flat without defects. High-quality cemented carbide should have a uniform and dense internal and external organizational structure, a smooth surface, and no cracks, bubbles, pits, adhesions, gaps and other defects.

[0003] Therefore, in response to the above-mentioned problems, a contoured clamp is now proposed, which can hold the product after closing by making the appearance dimensions of the clamp consistent with those of the product. The clamping position is on the side of the semi-finished product and does not contact the tip of the knife, thereby avoiding the problem of defects at the tip of the knife. Utility Model Content

[0008] As a further solution of the utility model: wherein, the clamping arm includes a fixed rod fixedly connected to the handle and an adjustable movable rod, the movable rod is hinged to the fixed rod, and the size of the surrounding space can be adjusted by adjusting the angle between the movable rod and the fixed rod.

[0009] As a further solution of the utility model: wherein, a sliding sleeve is sleeved on the handle, fixing ears are fixedly installed on both sides of the sliding sleeve, a guide groove for the sliding sleeve to move is provided on the handle, a fixing sleeve with the same shape and size as the sliding sleeve is fixedly installed on the end face of the handle close to the clamping arm, guide ears corresponding to the fixing ears are provided on both sides of the fixing sleeve, a positioning block is fixedly installed on the top of the movable rod, an elastic connecting rope is connected between the fixing ear and the positioning block, and the connecting rope passes through the guide ear.

[0010] As a further solution of the utility model: wherein, a fixing block is arranged between the movable rod and the fixed rod, and the deflection angle of the movable rod can be limited by the fixing block.

[0011] As a further solution of the utility model: wherein, the angle between the fixed rod and the movable rod when clamping the blade is 92°.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

After the deflection, the angle between the two movable rods becomes larger, and it is easier to clamp the blade. After clamping the blade, the sliding sleeve is released. At this time, under the action of the reset coil spring, it returns to its original state to complete the clamping action.

[0020] See also Figure 1 :It is a structural diagram of a clamp for clamping a fast-feed blade, the device includes a handle 10 and a clamping arm 20, and the clamping arm is arranged on both sides of the handle 10. In this embodiment, by placing the blade between the two clamping arms 20, a certain clamping force is applied to the blade side through the space formed between the clamping arms 20, so as to realize the removal and transfer of the blade. The problem of notch defects caused by direct contact is avoided.

[0021] On this basis, the present application also makes the following Figure 2 Improvements shown.

[0022] The handle 10 is sleeved with a sliding sleeve 11, and fixing ears 12 are fixedly installed on both sides of the sliding sleeve 11. The handle 10 is provided with a guide groove 13 for the sliding sleeve 11 to move. Under the action of the guide groove 13, the sliding sleeve 11 moves up and down on the surface of the handle 10. The handle 10 is fixedly installed with a fixing sleeve 14 with the same shape and size as the sliding sleeve 11 on the end face close to the clamping arm 20, and guide ears 15 corresponding to the fixing ears 12 are provided on both sides of the fixing sleeve 14.

[0023] like Figure 3 As shown, the clamping arm 20 includes a fixed rod 21 fixedly connected to the handle 10 and an adjustable movable rod 22, the fixed rod 21 is hinged to the movable rod 22, and a positioning block 23 is fixedly installed on the top of the movable rod 22, and an elastic connecting rope 24 is connected between the fixed ear 12 and the positioning block 23, and the connecting rope 24 passes through the guide ear 15.

[0024] like Figure 4 As shown, in this embodiment, when taking out an item, the distance between the sliding sleeve 11 and the handle 10 can be adjusted manually, and the sliding sleeve 11 can be pulled upward. Under the action of the connecting rope 24, the positioning block 23 is pulled to make the top of the movable rod 22 deflect around the hinge axis. A reset coil spring is sleeved on the hinge axis, and the tails of the two movable rods 22 move away from each other, and the distance between the movable rods 22 increases. Due to the enlarged distance, it is easy to set the clamping arm 20 on both sides of the blade. After releasing the sliding sleeve 11, it is withdrawn to the original position under the action of the reset coil spring. At this time, the movable rod 22 also returns to its original state to form a clamping embrace for the blade. When the blade needs to be taken out, the above actions can be repeated to complete it.

[0025] Furthermore, in order to ensure the stability of the movable rod 22 in the original position, a fixed block 30 is provided between the movable rod 22 and the fixed rod 21. The fixed block 30 can limit the deflection angle of the movable rod 22, so that after the movable rod 22 is reset, the angle formed between it and the fixed rod 21 is constant, which is 92°.

[0026] Furthermore, the movable block 22 and the fixed block 21 are made of thin strips of soft plastic.

[0027] Working principle: When in use, the sliding sleeve 11 is manually controlled to move upward on the handle 10, and the connecting rope 24 is used to drive the movable rod 22 to deflect outward. After the deflection, the angle between the two movable rods 22 becomes larger, and it is easier to clamp the blade. After clamping the blade, the sliding sleeve 11 is released. At this time, under the action of the reset coil spring, it returns to the original state to complete the clamping action. After it is taken and placed in the specified position, the above action is repeated to complete the unloading. This avoids the problem of notch defects caused by the contact of the blade tip during the clamping process.

[0028] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
