DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] In this application, unless otherwise clearly specified and limited, the terms "connection" and "fixation" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0021] In the description of the present application, it should be understood that the terms "longitudinal", "transverse", "horizontal", "top", "bottom", "up", "down", "inside" and "outside" etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.

[0023] like Figure 1-4 As shown, the utility model provides a special fixture for arc-shaped workpieces, including a base 10, which is fixedly mounted on a workbench. The above contents are all prior art, and the specific structure is not repeated here. The utility model also includes a fixing block 20 and a locking assembly 30.

[0024] The fixing block 20 is fixedly mounted on the base 10. An arc surface 21 is formed on the front side surface of the fixing block 20, and the arc surface 21 is adapted to the rear side surface of the arc-shaped workpiece.

[0025] The locking assembly 30 is arranged at the front side of the fixed block 20, and the locking assembly 30 includes a movable plate 31 and an adjusting screw 32. The movable plate 31 is arranged in the longitudinal direction, and a locking portion 33 is formed on the top of the movable plate 31, and the locking portion 33 extends in a direction close to the fixed block 20. The adjusting screw 32 passes through the movable plate 31 in the transverse direction and is threadedly connected to the movable plate 31, and the threaded end of the adjusting screw 32 is rotatably connected to the base 10.

[0026] The use process of the clamp is as follows: first, the staff member fits the rear side of the arc-shaped workpiece with the arc-shaped surface 21 on the fixed block 20. Then, the staff member turns the adjustment screw 32 with one hand and holds the movable plate 31 with the other hand to keep the movable plate 31 vertical. The movable plate 31 gradually approaches the arc-shaped workpiece until the locking portion 33 presses the arc-shaped workpiece and locks the arc-shaped workpiece. In this way, the arc-shaped workpiece is firmly fixed on the clamp.

[0027] It is worth noting that the locking portion 33 can directly press the front side of the arc-shaped workpiece to prevent the arc from shaking forward and backward; on the other hand, the locking portion 33 can also limit the bottom skirt of the arc-shaped workpiece within the limiting space 34 formed between the locking portion 33 and the base 10 to prevent the arc-shaped workpiece from shaking up and down. Therefore, the clamp has a better fixing effect on the arc-shaped workpiece.

[0028] In one embodiment, a guide groove 11 is formed on the base 10 , and a guide portion 35 is formed at the bottom of the movable plate 31 . The guide portion 35 is in sliding contact with the inner wall of the guide groove 11 .

[0029] This design can guide the movement of the movable plate 31. When the staff turns the adjusting screw 32, the movable plate 31 will always be in a vertical state due to the guiding effect of the guide part 35 and the guide groove 11. Therefore, the staff does not need to hold the movable plate 31 at the same time, which further facilitates the operation of the staff.

[0030] In one embodiment, there are three locking assemblies 30, which are arranged at intervals in the transverse direction. In this way, the locking parts 33 in the three locking assemblies 30 can lock the arc-shaped workpiece at three points, further improving the fixing effect of the arc-shaped workpiece.

[0031] In one embodiment, a plurality of positioning rings 12 are fixedly mounted on the base 10. The positioning rings 12 are located at the front side of the fixing block 20, and the positioning rings 12 are adapted to the insertion rods on the arc-shaped workpiece. The positioning rings 12 are designed to position the arc-shaped workpiece. When the staff inserts the insertion rods on the arc-shaped workpiece into the corresponding positioning rings 12, the rear side surface of the arc-shaped workpiece just fits together with the arc-shaped surface 21 on the fixing block 20.

[0032] In one embodiment, a side pressure assembly 40 is further included, and the side pressure assembly 40 includes a pressure block 41 and a clamping screw 42. The pressure block 41 is arranged on the left side and / or right side of the fixed block 20. The pressure block 41 is provided with a slot 43 that penetrates in the longitudinal direction, and the slot 43 is adapted to the side of the arc-shaped workpiece. The clamping screw 42 is arranged on the pressure block 41, and the threaded end of the clamping screw 42 passes through the pressure block 41 and is threadedly connected to the fixed block 20.

[0033] After the arc-shaped workpiece is locked by the locking assembly 30 , the staff will stick the pressing block 41 to the left side and / or right side of the fixing block 20 , at which time the slot 43 will fit together with the side of the arc-shaped workpiece, and then rotate the clamping screw 42 until the head of the clamping screw 42 clamps the pressing block 41 .

[0034] The side pressure assembly 40 can limit the side of the arc-shaped workpiece to prevent the arc-shaped workpiece from shaking left and right, thereby further improving the fixing effect of the arc-shaped workpiece.

[0035] In one embodiment, a pull rod 22 is fixedly mounted on the fixing block 20 to facilitate the staff to move the clamp.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
