TECHNICAL FIELD
[0001] The utility model relates to the field of tongs, specifically relates to a clamp assembling tong. BACKGROUND
[0002] Spring clamp is a connecting device, which is used for the connection and sealing of pipelines and is widely used in the field of automobiles.
[0003] The existing spring clamp comprises a clamp, the two ends of the clamp are respectively provided with a pin, in order to facilitate the customer to use the spring clamp after production, the spring clamp further comprises a retaining buckle, the retaining buckle is provided with a clamp hole corresponding to the two pins of the clamp, when the spring clamp is produced and assembled, first, the two pins of the clamp are moved towards each other to close, so that the clamp is opened, and then the two pins are abutted in the clamp hole of the retaining buckle, so that the clamp is kept in the opened state, so that the customer can only remove the retaining buckle to make the clamp tight at the position required to be connected.
[0004] In order to ensure that the pin is smoothly abutted in the clamp hole, it is necessary to check in advance whether the clamp can be smoothly opened, and to remove the inferior products in advance, so as to ensure the smoothness of subsequent mechanical assembly and the assembly efficiency. Specifically, the two pins are abutted by a clamp in advance by manual operation, if the clamp can be smoothly opened, the next assembly process can be entered. However, the clamp has large elasticity and needs large force to open, and there is a certain error in the manual operation on the assembly line, once the abutted position of the clamp deviates, the clamp is easily damaged to become a defective product. Therefore, a clamp is needed, which can reduce the manual operation error. SUMMARY
[0005] The utility model intends to provide a clamp assembling tong, which can reduce the manual operation error.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a clamp assembling tong, comprising a tong, the front end of the tong is respectively provided with a chuck, the chuck is provided with a limiting slot, the limiting slot is used for containing and abutting the pin of the clamp, the length of the limiting slot and the width of the pin of the wider end of the clamp are matched, and the both ends of the limiting slot are provided with limiting plates.
[0007] The beneficial effects of the present scheme are as follows:
[0008] 1. The width of the two pins of the clamp is usually wide and narrow, in order to improve the efficiency, the worker can abut the limiting slot to the pin of the clamp no matter how to hold the clamp, the length of the limiting slot and the width of the pin of the wider end of the clamp are matched in the present scheme, so that the pin of any width can be contained in the limiting slot.
[0009] 2. The wider pin is limited by the limiting groove, and the wider pin is prevented from sliding sideways by the limiting plate, thereby limiting the pin, preventing the clamp from tilting when the clamp is tightly clamped on the pin, thereby avoiding eccentric force of the clamp on the clamp, and thereby damaging the clamp.
[0010] Further, the front end of the clamp is provided with a first threaded hole, and the chuck is provided with a threaded head, and the threaded head and the first threaded hole are threadedly connected.
[0011] Further, the length direction of the first threaded hole is the direction of clamping the clamp.
[0012] Further, the length of the threaded head is less than the length of the first threaded hole.
[0013] Further, the limiting plate is welded on both sides of the chuck.
[0014] Further, the front end of the clamp is provided with a first threaded hole, and a bolt is threadedly connected in the first threaded hole, the chuck is provided with a second threaded hole, a connecting plate is arranged between the two limiting plates to form a U-shaped limiting part, the chuck is accommodated in the limiting part, a bolt hole is arranged on the limiting part, and the bolt is threadedly connected through the bolt hole and the second threaded hole.
[0015] Further, the clamp comprises two clamp legs, one of the clamp legs is provided with a limiting piece, and the other clamp leg is rotatably provided with a rotating plate, and the rotating plate is provided with a limiting notch.
[0016] The rotating plate is rotated, and when the limiting piece is accommodated in the limiting notch, the included angle between the two clamp legs is fixed.
[0017] Further, the material of the clamp is titanium alloy.
[0018] The scheme has the following effects:
[0019] 1. In order to ensure the durability of the clamp and facilitate the clamp to clamp the pin, the clamp usually has a large cross section, but this also leads to a heavy clamp. However, the inventor finds that during use, the main stress position of the clamp is the position of the middle rotation, and the farther away from the front end of the clamp, the greater the bending moment generated by the reaction force.
[0020] The bending moment on the front end of the clamp is small, therefore, the inventor opens a first threaded hole at the front end of the clamp, thereby reducing the weight of the front end of the clamp, so as to facilitate the worker to use;
[0021] In the prior art, the chuck is usually welded with the front end of the clamp, and the welding requires a sufficient size of the welding head to meet the welding conditions, thereby causing the size of the chuck to be inconvenient to reduce and optimize; in the present scheme, the chuck and the end of the clamp are threadedly connected, the connecting process is optimized, and the size of the chuck is no longer limited; although the threaded head is added, as long as the length of the threaded head is less than the length of the first threaded hole, the total weight is still lighter than that of the clamp in the prior art.
[0022] 2. The chuck and the end of the clamp are threadedly connected to facilitate replacement of the chuck, so that a lighter and smaller chuck can be used, and even if wear occurs, the chuck can be easily replaced without replacing the entire clamp.
[0023] 3. Since the limiting plate does not need to be in direct contact with the clamp, the stress is small, and the limiting plate mainly plays a limiting role, so the limiting plate and the chuck can be welded to fix the relative position therebetween.
[0024] 4. The limiting plate and the chuck can also be connected by bolts to facilitate replacement of the limiting plate, and the limiting plate can be made of a material that is lower in rigidity and cheaper than the chuck, which can reduce costs on the one hand and fill the gap between the chuck and the clamp on the other hand, reduce the part of the chuck in contact with air, and increase the durability of the chuck.
[0025] 5. The clamp is made of titanium alloy, which is lighter and easier to operate than the cast iron used in the prior art. BRIEF DESCRIPTION OF DRAWINGS

[0033] Example 1
[0034] A clamp assembly clamp, used for objects such as Figure 1 The clamp 1 shown has two pins 11. When the clamp 1 is in the open state, the two pins 11 are close to each other, and the inner diameter of the clamp 1 increases; when the clamp 1 is in the closed state, the two pins 11 are far apart, and the inner diameter of the clamp 1 decreases.
[0035] Example 1 is basically as follows Figures 2-4 As shown: A clamp assembly clamp, the clamp being made of titanium alloy. Includes clamps, such as... Figure 2 As shown, the clamp includes two hinged arms 2. The hinged position divides the clamp arms 2 into two parts: a clamp head 21 and clamp legs 22. The clamp head 21 is used to clamp the two pins 11 of the clamp 1, thereby bringing the two pins 11 closer together. The clamp legs 22 are used for hand operation. The length of the clamp head 21 is shorter than that of the clamp legs 22, thus forming a force-saving lever, so that the worker can clamp the pins 11 more easily. The clamp head 21 is the structure of the front end of the clamp.
[0036] like Figure 2 , Figure 3 As shown, each of the two clamp heads 21 is equipped with a clamp 3 and a limiting part 4. The limiting part 4 includes two parallel limiting plates 41, with a connecting plate 42 integrally formed between the limiting plates 41. The two limiting plates 41 and the connecting plate 42 form a U-shaped limiting part 4. The clamp 3 is welded into the U-shaped opening of the limiting part 4. A threaded head (not shown in the figure) is welded to the side of the connecting plate 42 of the limiting part 4 away from the clamp 3. The threaded head is a short post with threads. A first threaded hole 27 is opened on the clamp head 21. The length direction of the first threaded hole 27 is the direction of clamping the clamp 1. The threaded head is threadedly connected to the first threaded hole 27, and the length of the threaded head is less than the length of the first threaded hole 27.
[0037] The clamp 3 has a V-shaped limiting groove 31 on one side for holding the pin 11. The limiting groove 31 is perpendicular to the length direction of the clamp head 21. The limiting groove 31 is used to accommodate and press the pin 11 of the clamp 1. The length of the limiting groove 31 is matched with the width of the pin 11 at the wider end of the clamp 1. The limiting plate 41 of the limiting part 4 is set at both ends of the limiting groove 31, thereby realizing the limiting of the pin 11 in the limiting groove 31.
[0038] A limiting element 23 is welded on one of the clamp legs 22. In this embodiment, the limiting part 4 is a limiting post. A rotating plate 24 is rotatably provided on the other clamp leg 22. A limiting notch is opened on the rotating plate 24. The limiting notch includes a first limiting notch 25 and a second limiting notch 26.
[0039] Separate the two clamp legs 22 and rotate the rotating plate 24. When the limiting member 23 is accommodated in the first limiting notch 25, the two clamp legs 22 remain separated.
[0040] As shown in Figure 4 two clamping legs 22 are closed, rotate the rotating plate 24, when the limiting part 23 is contained in the second limiting gap 26, the two clamping legs 22 remain closed.
[0041] Embodiment 2
[0042] The difference between embodiment 2 and embodiment 1 is that, as shown in Figure 5 the threaded head on the limiting part 4 is cancelled, the threaded head is replaced by a bolt hole, the limiting part 4 and the chuck 3 are changed to detachable connection, the chuck 3 is provided with a second threaded hole 28, the chuck 3 is contained in the limiting part 4, a bolt is threadedly connected in the first threaded hole 27, and the bolt is threadedly connected through the bolt hole and the second threaded hole 28.
[0043] The above is only the embodiment of the present application, and the specific technical scheme and / or common knowledge of the scheme are not described in detail. It should be pointed out that for those skilled in the art, without departing from the technical scheme of the present application, a number of modifications and improvements can be made, which should also be regarded as the protection scope of the present application, and these will not affect the effect and practicality of the present application.
