[0028] The following disclosure provides many different embodiments or examples for implementing different structures of the embodiments of the present utility model. To simplify the disclosure of the embodiments of the present utility model, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the embodiments of the present utility model.

This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between various embodiments and / or settings discussed.

[0029] This embodiment provides a fixture for a pipe wrench, which is used to clamp the pipe wrench 9. Refer to Figure 5 As shown, the pipe wrench 9 includes a body portion 92 and a head portion 91 connected in sequence from top to bottom. Second grooves 93 are provided on both side surfaces of the body portion 92. The second grooves 93 are arranged in the up-down direction and are parallel to the body portion 92. The upper surface of the head portion 91 is the processing surface.

[0030] Refer to Figures 1-3 As shown, the above-mentioned fixture for a pipe wrench includes a mounting base 1, a pair of clamping blocks 2 arranged at intervals in the first direction (i.e., the direction of the arrow in Figure 1 ) in the mounting base 1 and used to cooperatively clamp the pipe wrench 9, a first groove 3 recessed in the inner side of the clamping block 2 in the positive or negative direction of the first direction and used to cooperate with the head portion 91 and the body portion 92 of the pipe wrench 9 to be embedded, and a limiting convex portion 4 protruding from the first groove 3 and used to extend into the second groove 93. The limiting convex portion 4 abuts against the bottom of the second groove 93 arranged in the up-down direction. By providing the limiting convex portion 4 pressing against the bottom of the second groove 93 in the first groove 3, the pipe wrench 9 can be pressed from the up-down direction, ensuring stable limiting of the pipe wrench 9.

[0031] Wherein, the bottom of the first groove 3 has an abutting surface 31 for abutting against the bottom end surface of the head portion 91 of the pipe wrench 9. By setting the height of the abutting surface 31, the processing surface at the top end of the head portion 91 can protrude upward from the pair of clamping blocks 2, so as to facilitate being processed by a processing mechanism.

[0032] Refer toFigure 4 As shown, the above-mentioned clamping block 2 includes a first sub-block 21 for cooperating with and clamping the head 91 of the pipe wrench 9, and a second sub-block 22 connected above the first sub-block 21 for cooperating with and clamping the body 92 of the pipe wrench 9. Since the width of the head 91 in the first direction is greater than the width of the body 92 in the first direction, the inner surface of the second sub-block 22 is located inside the inner surface of the first sub-block 21, and the limiting convex portion 4 protrudes from the inner surface of the second sub-block 22 in the positive or negative direction of the first direction.

[0033] In this embodiment, the length of the second sub-block 22 in the up-and-down direction is shorter than the length of the body 92 of the pipe wrench 9 in the up-and-down direction, so that the body 92 of the pipe wrench 9 can extend upward out of the second sub-block 22. Through this setting, while ensuring stable clamping of the pipe wrench 9, the consumables of the clamping block 2 are saved.

[0034] At least one of the pair of clamping blocks 2 is slidably disposed in the mounting seat 1 in the first direction. The fixture further includes a driving block 5 that is slidably disposed in the mounting seat 1 in the first direction and is connected to the outside of the sliding clamping block 2.

[0035] In this embodiment, a first blocking block 6 for limiting one of the clamping blocks 2 is provided at one end of the mounting seat 1 in the first direction, and the driving block 5 is connected to the outside of the other clamping block 2. The pair of clamping blocks 2 are disposed between the first blocking block 6 and the driving block 5.

[0036] See Figure 1 As shown, the first blocking block 6 protrudes upward from the mounting seat 1, and the corresponding clamping block 2 abuts against the first blocking block 6 through its outer side surface. In this embodiment, the corresponding clamping block 2 is mounted on the first blocking block 6.

[0037] A second blocking block 7 for limiting the driving block 5 is provided at the other end of the mounting seat 1 in the first direction. The fixture further includes a driving mechanism 8 disposed on the mounting seat 1. The driving mechanism 8 is used to drive the driving block 5 to slide in the mounting seat 1 in the first direction, so as to drive the movable clamping block 2 to move toward or away from the other clamping block 2, thereby realizing clamping and releasing of the pipe wrench 9.

[0038] In this embodiment, the driving mechanism 8 includes a hydraulic cylinder body 81 connected to the mounting seat 1, and a push rod 82 that is telescopically disposed in the hydraulic cylinder body 81 along its own length extension direction. The push rod 82 is parallel to the first direction. The push rod 82 passes through the mounting seat 1 in the first direction and is connected to the driving block 5. See Figure 2 As shown, the push rod 82 is connected to the bottom of the driving block 5. See Figure 3 As shown, in order to prevent the bottom of the clamping block 2 from interfering with the telescopic movement of the push rod 82, the bottoms of the pair of clamping blocks 2 are both higher than the bottom of the driving block 5.

[0039] The above embodiments are only for illustrating the technical concept and features of the present utility model, and the purpose is to enable those skilled in the art to understand the content of the present utility model and implement it accordingly. It is not intended to limit the protection scope of the present utility model. Any equivalent changes or modifications made according to the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
