Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a clamping device. Background Technology

[0002] As attached Figure 1 The diagram illustrates a machining scenario for a component. The machining process is as follows: First, the component is placed on a worktable, and several pressure plates surrounding the component firmly press it against the worktable to secure it. Then, a cutting tool is activated to machine certain sides (or other surfaces) of the component. Initially, the tool is positioned on the upper side of the worktable with its tip pointing vertically downwards. During machining, the tool descends sequentially to predetermined positions to machine each surface one by one.

[0003] However, this processing method has certain drawbacks: when the tool is machining the surface of the part, the presence of the pressure plate hinders the movement of the tool. This means that after machining one surface, the tool needs to be raised above the pressure plate, pass over the pressure plate, move to another surface, and then descend to the next surface to machine. When there are many surfaces to be machined, or many pressure plates, the tool will have to perform multiple raising and lowering actions, resulting in long processing time and high manufacturing costs. It can also lead to discontinuous machining lines and certain differences in the appearance of the part surface. Utility Model Content

[0021] Embodiment 1

[0022] In conjunction with the drawings Figure 2 to the drawings Figure 4 , the embodiment provides a clamping device, which comprises a machining platform 1, a first stop block 2 is fixedly arranged on one side of the machining platform 1, a push block mechanism is arranged on the other side of the machining platform 1, and a clamping area of a part is formed between the first stop block 2 and the push block mechanism.

[0023] The first straight slot 11 and the second straight slot 12 are perpendicular to each other and constitute a T-shaped through slot together, and the third straight slot 13 is arranged in the first straight slot 11 and penetrates the machining platform 1. The push block mechanism comprises a first driving part 3, a clamping sliding block 4 and a clamping block 5. The first driving part 3 is located at the bottom of the machining platform 1. The clamping sliding block 4 is connected with the output end of the first driving part 3, and the clamping sliding block 4 comprises an outgoing section 40 which penetrates the third straight slot 13, and the end of the outgoing section 40 is provided with a first wedge surface 41. The clamping block 5 comprises a second stop block 50, a sliding section 51 and a matching section 52 which are connected in sequence. The sliding section 51 is in sliding fit with the second straight slot 12, the matching section 52 is in sliding fit with the third straight slot 13, the side of the matching section 52 facing the outgoing section 40 is provided with a second wedge surface 53, and the first wedge surface 41 is in abutment with the second wedge surface 53. The machining platform 1 is further provided with a fastening plate 6 which covers the upper side of the clamping block 5, and the fastening plate 6 is provided with a notch for avoiding the second stop block 50.

[0024] For the clamping device of the embodiment, the working mode is as follows: first, the part to be machined is placed on the machining platform 1, specifically in the clamping area between the first stop block 2 and the push block mechanism. Then, the push block mechanism is started, the first driving part 3 pushes the clamping sliding block 4 to move upward along the height direction, and the outgoing section 40 will move upward in the third straight slot 13. During the movement of the outgoing section 40, the first wedge surface 41 thereon will abut against the second wedge surface 53 on the matching section 52. Both the first wedge surface 41 and the second wedge surface 53 are inclined surfaces. With the movement of the outgoing section 40, the sliding section 51 will move along the second straight slot 12, driving the second stop block 50 to move towards the first stop block 2, until the second stop block 50 abuts against the side surface of the part, thereby forming a clamping force between the second stop block 50 and the first stop block 2 to stably clamp the part on the machining platform 1. In order to ensure the clamping effect, in the preferred embodiment, the second stop block 50 is arranged opposite to the corresponding first stop block 2.

[0025] The first driving part 3 is generally a pneumatic cylinder or a hydraulic cylinder. In the more preferred embodiment, a support 7 is fixedly arranged at the bottom of the machining platform 1, and the first driving part 3 is fixed with the support 7, thereby fixing itself with the machining platform 1. Thus, the clamping device is modularized, and in actual production, the modularized clamping device can be flexibly applied to the production line.

[0026] And, in order to avoid the clamping block 5 from moving in the height direction when being pushed by the clamping slider 4, the embodiment is further provided with a fastening plate 6 fixed on the machining platform 1, which can limit the movement of the clamping block 5 in the height direction, and the notch on the fastening plate 6 can be used to avoid interference with the second stop block 50. And this arrangement can expose only the second stop block 50 of the push block mechanism, fully hiding the rest of the push block mechanism, avoiding unnecessary risks caused by the exposure of the rest of the push block mechanism during the machining process.

[0027] In further embodiments, the machining platform 1 is provided with an assembly groove 14, which has the same shape and depth as the fastening plate 6. In this way, the clamping area on the machining platform 1 can be kept as flat as possible, avoiding the reduction of the effective area of the clamping area due to the avoidance of the protrusions.

[0028] In other embodiments, the machining platform 1 is further provided with a pressing plate mechanism, which includes a second driving part 80 and a pressing block 81, the second driving part 80 is used to drive the pressing block 81 to move up and down, the output end of the second driving part 80 penetrates the machining platform 1 from bottom to top and is fixedly connected with the pressing block 81, and part of the pressing block 81 extends to the clamping area. The pressing plate mechanism can drive the pressing block 81 to move through the up and down movement of the output end of the second driving part 80, so as to press the part on the machining platform 1. In this way, the part can be fixed in both horizontal and height directions, greatly improving the clamping stability of the clamping device to the part. The second driving part 80 can also be a pneumatic cylinder or a hydraulic cylinder.

[0029] In further embodiments, the part of the pressing block 81 extending to the clamping area is provided with a positioning piece 82, which is used to insert the part being machined. In this embodiment, the positioning piece 82 can be inserted into some mating surfaces of the part, further enhancing the clamping effect on the part.

[0030] In summary, in view of the technical problems of the defects of the traditional part machining method, the clamping device of the embodiment can realize clamping of the part through fewer push block mechanisms and first stop blocks 2. This clamping method has stronger clamping capacity and almost no height space occupied, and the tool does not need to be repeatedly lifted and lowered, effectively improving the machining efficiency. And since the movement path of the tool is simpler, the machining lines on the surface of the part are easier to keep continuous, thereby avoiding differences in the appearance of the surface of the part as much as possible.

[0031] The above describes the utility model and its embodiments in a schematic manner, and the description is not restrictive, and the drawings only show one of the embodiments of the utility model, and the actual structure is not limited thereto. Therefore, if a person of ordinary skill in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are designed without creativity, and all should belong to the protection scope of the utility model.
