Embodiment 1

[0039] as attached Figure 1-3 As shown in the main body of the fixture, the main body of the fixture is clamped on the bench vise, and the bench vise is fixed on the drill press, and the drill press is first pressed down so that the center drill is opposite to the positioning hole 5 on the fixture main body, and then fixed; When the main body is fixed in the bench vise, it is often necessary to place a shim on the bottom surface, and the shim should avoid the positioning hole 5; the main body of the fixture in this example is processed by the machining center, and it is necessary to ensure that the center of the positioning hole 5 is at a distance from the chip removal groove. 1 The size of the left side is consistent with the size of the duckbill hammer 6 required by the drawings. The groove width of clamping groove 2 is slightly greater than the width of duckbill hammer 6. Generally, the blank material used in practice is 14mm*14mm*68mm brass square material, which is proc...

Embodiment 2

[0045] as attached Figure 4 As shown, compared with the first embodiment, the depth of the chip removal groove 1 of the fixture body in this example is greater than that of the clamping groove 2. The advantage is that it can accommodate more copper chips and reduce the number of cleanings during the center hole machining process.

Embodiment 3

[0047] as attached Figure 5 As shown, compared with the first embodiment, the left side of the clamp body in this example has a threaded groove 9 transversely, and the threaded groove 9 is fitted with a fine-tuning nut 10 , and at the same time, the inclined step 7 and the burr-containing groove 8 can be reduced. The advantage of this example is that when processing the fixture body, it is not necessary to ensure that the center of the positioning hole 5 is the same as the size of the duckbill hammer 6 on the left side of the chip removal groove 1, which is consistent with the size of the duckbill hammer 6 required by the drawing. The distance is greater than the requirements of the drawing, which greatly reduces the production cost. Before use, it is only necessary to adjust the fine-tuning nut 10 through the standard-processed duckbill hammer 6 . In addition, in this example, when processing the blank with an inclined plane, the fine-tuning nut 10 is centered against the d...

Abstract

The invention discloses a drilling clamp for duckbilled hammer manufacturing. The drilling clamp comprises a clamp main body, wherein a chip groove is vertically formed in the clamp main body, a clamping groove is transversely formed in the clamp main body, the middle of the chip groove communicates with the clamping groove, and the chip groove and the clamping groove form a T-shaped notch structure; a chip containing groove is vertically formed in the bottom surface, opposite to the left side of the clamping groove, of the chip discharging groove, and a chip discharging hole is formed in the bottom surface, in front of and behind the chip containing groove, of the chip groove; a positioning hole is formed in the bottom surface of the clamping groove; a duckbilled hammer or a blank is arranged in the clamping groove in a matched mode, and the groove width of the clamping groove is larger than the widths of the duckbilled hammer and the blank. The drilling clamp can be combined with a bench vice to be fixed to a drilling machine, is used for machining positioning holes of duckbilled hammers or blank materials, and is convenient in clamping, small in machining error and high in efficiency. The drilling clamp reduces the drilling process, improves the machining efficiency on the premise of ensuring the practice precision requirement, and is suitable for being popularized and used in colleges and universities for carrying out duckbilled hammer machining projects.

Description

【Technical field】 [0001] The invention relates to the technical field of duckbill hammer processing, in particular to the technical field of drilling fixtures made of duckbill hammers. 【Background technique】 [0002] The duckbill hammer is a hammer with a head like a duckbill. The production of the duckbill hammer is often used in the important teaching link of metalworking practice. The processing of the duckbill hammer involves several processes such as drilling, tapping, milling, turning, threading, and assembly. For students, the above-mentioned internship process can build a deep understanding of metalworking. Drilling and tapping mainly complete the processing of the matching hole, milling mainly completes the processing of the shape of the hammer head, turning and threading mainly completes the processing of the hammer handle, and assembly is to fit the hammer handle into the hammer head. [0003] In the above-mentioned projects, drilling is not an important content ...
