Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical manufacturing fixture technology, and more specifically, to a component clamping device for mechanical manufacturing. Background Technology
[0002] In the basic structure of some large mechanical equipment, short steel pipes are welded into frames or support structures, such as the bed of a large machine tool or the support of a large crane. The structure formed by welding short steel pipes can provide strong support and stability, ensuring the accuracy and safety of the equipment during operation.
[0003] For small, individual workshops, the support structure is often welded in-house to save costs and eliminate the need for purchase. Currently, when welding steel pipes, two pipes are placed on a horizontal surface, and the welding surfaces are adjusted to fit together. A weight is used to press the pipes down before welding. During the welding process, the force applied to the pipes is controlled to prevent them from moving. However, this method is very time-consuming and can easily cause the pipes to move, affecting the welding result. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0029] Example
[0030] Reference Figures 1-4 This utility model provides a technical solution: a component clamping device for mechanical manufacturing, including a base plate 1, a clamping mechanism 3 and a rotating mechanism 4. A V-shaped plate 2 is installed on the upper surface of the base plate 1. The clamping mechanism 3 includes a positioning frame 31, which is installed on the outer side of the V-shaped plate 2. A first screw 32 is set on the positioning frame 31. A clamping block 33 is installed at one end of the first screw 32. The rotating mechanism 4 is installed on one side of the positioning frame 31 and is used to clamp one end of the steel pipe and control the rotation of the steel pipe.
[0031] A positioning frame 31 is installed on the outer side of the V-shaped plate 2. A first screw 32 is threaded onto the positioning frame 31. One end of the first screw 32 is rotatably connected to the clamping block 33. During operation, controlling the first screw 32 to move downward will drive the clamping block 33 to move downward and squeeze the steel pipe, so that the steel pipe can stably contact the V-shaped plate 2. At the same time, it ensures that the end faces of the two steel pipes are tightly fitted, which facilitates welding of the steel pipe, saves time, and prevents the steel pipe from moving during the welding process.
[0032] In a preferred embodiment, the rotating mechanism 4 includes a connecting plate 41, a hollow cover 42, and a positioning element 43. The connecting plate 41 is stably installed on the outer side of the positioning frame 31, and the hollow cover 42 is rotatably installed on the connecting plate 41. The hollow cover 42 is located on the inner side of the connecting plate 41. A protruding rod 5 is stably installed on the outer side of the hollow cover 42, and a groove is provided on the inner side of the hollow cover 42. An end cap 6 is stably installed inside the groove. The positioning element 43 includes a second screw 4301 and a clamping plate 4302. The second screw 4301 is threaded onto the end cap 6, and the clamping plate 4302 is rotatably installed at the bottom end of the second screw 4301. A rubber pad is provided on the inner side of the clamping plate 4302.
[0033] In actual use, this device first welds the exposed joint of the two steel pipes. After the exposed joint is welded, the steel pipe needs to be rotated. At this time, the first screw 32 can be turned upward to reduce the squeezing force of the clamping block 33 on the steel pipe. Then, the hollow cover 42 is turned. The rotation of the hollow cover 42 will cause the end cover 6 to rotate, which will in turn cause the steel pipe to rotate. Since the edges of the steel pipe are relatively sharp, it is easy to scratch the hand when rotating it by hand. Therefore, the device controls the rotation of the end cover 6 to control the rotation of the steel pipe, change the exposed position of the steel pipe, and continue the welding operation on the steel pipe.
[0034] By rotating and installing a rotating rod 7 inside the connecting plate 41, one end of the rotating rod 7 is stably connected to the outer surface of the hollow cover 42. The rotating rod 7 is rotated and installed inside the connecting plate 41, and both ends of the rotating rod 7 extend out of the connecting plate 41. In this way, the hollow cover 42 can be easily installed on the rotating rod 7, thereby enabling the hollow cover 42 to rotate stably.
[0035] A rubber pad is glued to the inner side of the V-shaped plate 2, and the two ends of the V-shaped plate 2 are respectively set as openings.
[0036] The first screw 32 is threadedly connected to the positioning frame 31. The circular plate 8 is rotatably installed at the bottom of the first screw 32, and the clamping block 33 is stably installed at the bottom of the circular plate 8. The clamping block 33 is set in an inverted V shape and is positioned above the V-shaped plate 2. When it is necessary to clamp the steel pipe, the first screw 32 can be screwed downward, thereby driving the clamping block 33 to move downward. The clamping block 33 will clamp the steel pipe, so that the steel pipe is stably placed on the V-shaped plate 2 for operation.
[0037] Specifically, the working process or working principle of the mechanical manufacturing parts clamping device is as follows: Currently, when welding steel pipes, two steel pipes are placed on a horizontal surface, and the welding surfaces of the two steel pipes are adjusted to fit together. A weight is used to press the steel pipes down before welding. During the welding process, the operating force on the steel pipes is controlled to avoid moving the steel pipes. However, this operation is very time-consuming and can easily cause the steel pipes to move, affecting the welding effect. Therefore, this device was designed to solve this problem.
[0038] This device can clamp two steel pipes, tightly fitting their welded surfaces together for stable welding. Specifically, two small steel pipes are placed inside the inner chamber of the V-shaped plate 2, with the outer surface of the pipes contacting the inner surface of the V-shaped plate 2 for support. One end of one of the pipes is inserted into the end cap 6, pressing against its inner wall. The second screw 4301 is then turned, pushing the clamping plate 4302 to move. The clamping plate 4302 clamps one end of the steel pipe. Furthermore, the device uses two second screws 4301 and two clamping plates 4302, symmetrically positioned on the end cap 6, ensuring stable clamping of one end of the steel pipe during use.
[0039] After the steel pipe is placed, the first screw 32 can be turned downwards. Turning the first screw 32 downwards will cause the circular plate 8 to move downwards and control the clamping block 33 to move downwards. As the first screw 32 continues to be turned downwards, it will control the clamping block 33 to clamp the outer surface of the steel pipe. Furthermore, the two clamping blocks 33 clamp the outer surfaces of the two steel pipes respectively, which can stably place the steel pipe on the V-shaped plate 2 for operation.
[0040] Workers use a welding torch to weld the joint between the two steel pipes. After the exposed joint is welded, the first screw 32 is turned upwards, which moves the clamping block 33 upwards, reducing the squeezing force of the clamping block 33 on the steel pipe. Then, the hollow cover 42 is rotated, which can rotate the end cap 6. Since part of the joint between the two steel pipes has been welded together, rotating the end cap 6 can rotate both steel pipes simultaneously, exposing the unwelded part. Then, the steel pipes are clamped and positioned in the same way as described above, and welding can continue.
[0041] Finally, after all the joints of the steel pipes are welded, the steel pipes can be removed from the V-shaped plate 2.
