Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to an auxiliary tooling clamp for processing pipe clamps. Background Art

[0002] In the field of machinery, it is often necessary to process some irregular parts. For example, there is a type of part with an arc groove on the side, and the top hole needs to be processed. Some areas are thin and easy to deform during secondary processing. There are many working surfaces during use, and the shape and position tolerance requirements are high. It is necessary to use the side arc groove A as a reference to ensure that the axis of the arc groove A is perpendicular to the axis of the hole.

[0003] After machining the side grooves of the single part described above, when machining the holes and top surfaces, the existing fixtures are difficult to ensure the position requirements, and the clamping reference is the bottom surface of the part, which is an unprocessed plane with low requirements for surface roughness and flatness. If this plane is used as the reference, it is difficult to ensure the verticality and size requirements of the hole and the groove axis. Workers need to repeatedly calibrate and find the reference and origin during clamping, which consumes a lot of preparation time and easily leads to the scrapping of parts. Utility Model Content

[0004] In order to solve the problems of the prior art, the utility model provides an auxiliary tooling fixture for processing pipe clamps, which is used to clamp pipe clamp parts, and comprises a fixture body, wherein the fixture body comprises two fixture blocks, the two fixture blocks are integrally formed, and a positioning groove is provided between the two fixture blocks; the tops of the two fixture blocks are provided with concave grooves, and a positioning pin rod is overlapped between the two concave grooves;

[0005] The top of the pipe clamp part is provided with a surface to be processed and a plurality of holes to be processed, and the bottom surface of the pipe clamp part is provided with an arc groove and a plane;

[0006] The pipe clamp part is disposed in its entirety in the positioning groove and enables the inner wall of the arc groove to contact the outer surface of the positioning pin rod.

[0007] A further solution is that the pipe clamp part is restricted in the positioning groove by a limiting mechanism, and the limiting mechanism includes a locking bolt, wherein a bolt hole is opened on the side of one of the clamp blocks, and the bolt hole is connected to the interior of the positioning groove. An internal thread is provided in the bolt hole, and the internal thread cooperates with the external thread on the outer surface of the locking bolt.

[0008] A further solution is that the number of the limiting mechanisms is set to three, and the three limiting mechanisms are arranged along the length direction of the clamp block.

[0009] A further solution is that the width of the concave groove is greater than the diameter of the circular cross section of the positioning pin rod.

[0010] Beneficial effects of the utility model:

[0011] The utility model places the positioning pin rod between two concave grooves, and then places the pipe clamp part into the positioning groove, and makes the inner wall of the arc groove contact the outer surface of the positioning pin rod. After ensuring that the pipe clamp part is flat, the pipe clamp part is further clamped and limited by the limiting mechanism to ensure that the pipe clamp part cannot move in the positioning groove.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] like Figure 1-3 As shown, an embodiment of the utility model discloses an auxiliary tooling fixture for processing a pipe clamp, which is used to clamp a pipe clamp part 2, and includes a fixture body 1, wherein the fixture body 1 includes two fixture blocks 10, the two fixture blocks 10 are integrally formed, and a positioning groove 11 is provided between the two fixture blocks 10; a concave groove 12 is provided on the top of the two fixture blocks 10, and a positioning pin rod 13 is overlapped between the two concave grooves 12;

[0018] The top of the pipe clamp part 2 is provided with a surface 20 to be processed and a plurality of holes 21 to be processed, and the bottom surface of the pipe clamp part 2 is provided with a circular arc groove 22 and a plane 23;

[0019] The pipe clamp part 2 is disposed in its entirety in the positioning groove 11 so that the inner wall of the arc groove 22 contacts the outer surface of the positioning pin rod 13 .

[0020] The embodiment of the utility model can achieve the above arrangement by first placing the positioning pin between the two concave grooves, and then placing the pipe clamp part into the positioning groove, and making the inner wall of the arc groove contact the outer surface of the positioning pin. After ensuring that the pipe clamp part is flat, the pipe clamp part is further clamped and limited by the limiting mechanism to ensure that the pipe clamp part cannot move in the positioning groove.

[0021] Therefore, this embodiment can realize the use of the arc groove as the positioning reference through the cooperation of the positioning pin and the clamp body. The positioning groove and the pipe clamp part form a clearance fit to ensure that the pipe clamp part can be smoothly placed in the positioning groove, and then the pipe clamp part is locked by three locking bolts.

[0022] It should be noted that the positioning pin rod of this embodiment is used to assist in positioning and to support the thin wall of the pipe clamp part during processing to prevent the part from being deformed by the cutting force.

[0023] The fixture provided in this embodiment is easy to operate, meets the positioning and clamping requirements during part processing, and reduces the clamping time of workers.

[0024] In this embodiment, the pipe clamp part 2 is limited in the positioning groove 11 by a limiting mechanism, and the limiting mechanism includes a locking bolt 30. A bolt hole is opened on the side of one of the clamp blocks 10, and the bolt hole is connected to the interior of the positioning groove 11. An internal thread is provided in the bolt hole, and the internal thread cooperates with the external thread on the outer surface of the locking bolt 30.

[0025] The embodiment of the utility model can realize the clamping and limiting of the pipe clamp part by rotating the locking bolt so that the end of the locking bolt passes through the bolt hole and enters the limiting groove to abut against the side surface of the pipe clamp part.

[0026] In this embodiment, the number of the limiting mechanisms is set to three, and the three limiting mechanisms are arranged along the length direction of the clamp block 10 .

[0027] Through the above arrangement, the present embodiment can achieve the maximum limit effect by setting three limit mechanisms, so that the pipe clamp part is firmly pressed and limited in the positioning groove.

[0028] In this embodiment, the width of the concave groove 12 is slightly larger than the diameter of the circular cross section of the positioning pin rod 13 .

[0029] Through the above arrangement, the present embodiment can ensure that the positioning pin rod can be properly engaged in the positioning groove to avoid the positioning pin rod rolling in the positioning groove, thereby affecting the clamping of the pipe clamp parts.

[0030] Finally, it should be noted that the above only describes in detail the specific embodiments of the utility model. However, the utility model is not limited to the specific embodiments described above. Equivalent modifications and substitutions made by technicians in this field to the utility model are also within the scope of the utility model. Therefore, equal changes and modifications made without departing from the spirit and scope of the utility model are all included in the scope of the utility model.
