Description

Technical Field

[0001] The utility model belongs to the technical field of carburizing equipment and relates to an anti-seepage tooling for electric wrench parts. Background Art

[0002] Carburizing is a heat treatment method used to improve the hardness, wear resistance and corrosion resistance of metal materials. The process is usually carried out at a temperature of 800°C to 1000°C, exposing the material to a gas or liquid containing carbon elements, so that carbon atoms penetrate into the surface of the material and combine with it to form a high-hardness carburized layer. In actual production, carburizing increases hardness while also increasing brittleness. Some parts of the parts do not want to be carburized. For example, when the plate shaft in the electric wrench is carburized, the lower surface of the striking part needs to maintain its toughness, so anti-seepage during carburizing is particularly important.

[0003] The conventional treatment method for carburizing anti-seepage is to apply anti-seepage paint. However, due to the shedding of paint or uneven application, it is difficult to achieve 100% anti-seepage of parts. Therefore, it is necessary to develop a new carburizing anti-seepage method to avoid carburization of the anti-seepage part. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an anti-seepage tooling for electric wrench parts, which can perform anti-seepage treatment on parts of the parts that do not require carburizing, and has the advantages of simple structure, low cost and good anti-seepage effect.

[0005] In order to solve the above technical problems, the purpose of the utility model is achieved through the following technical solutions:

[0007] In the anti-seepage tooling of the electric wrench parts, the main shaft and the mounting hole are clearance-matched. Preferably, the clearance between the main shaft and the mounting hole is a small clearance for smoothly inserting the main shaft.

[0008] In the above-mentioned anti-seepage tooling of an electric wrench part, the upper end of the main shaft forms an enlarged pull shaft head, the striking part is arranged on both sides of the pull shaft head, and a step structure is formed between the pull shaft head and the main shaft. After the main shaft is inserted into the mounting hole, the step structure forms an axial limiting structure, and the lower surface of the pull shaft head is in contact and connected with the upper surface of the tooling frame to form an anti-seepage structure.

[0009] In the anti-seepage tooling of the electric wrench parts, the tooling frame is a mesh plate structure, including a plurality of horizontal bars and vertical bars arranged at intervals, and the mounting hole is arranged at the intersection of the horizontal bars and the vertical bars. Preferably, the horizontal bars and the vertical bars have the same width, and preferably, the mounting hole is arranged in the center.

[0010] In the anti-seepage tooling of the electric wrench parts, the width of the horizontal and vertical strips is greater than the width of the striking part. Furthermore, the width of the horizontal and vertical strips is greater than the radial dimension of the spindle head.

[0015] The utility model provides an anti-seepage fixture for electric wrench parts. The electric wrench parts to be carburized are placed on a fixture frame. The surface of the fixture frame is in contact with and connected to the parts that need to be anti-seepage. During the carburizing process, the gas or liquid containing carbon elements cannot contact the anti-seepage part, so the anti-seepage part can be prevented from being carburized. The anti-seepage fixture provided by the utility model can ensure the hardness of the striking part of the wrench shaft while retaining the toughness of the lower surface of the striking part. The utility model has the advantages of simple structure, low cost and good anti-seepage effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] A seepage-proof tooling for an electric wrench part, wherein the electric wrench part 1 is a wrench shaft, comprising a main shaft 2 and a striking part 3 arranged at the end of the main shaft 2, the seepage-proof tooling is loaded with the electric wrench part 1 to be carburized, and the seepage-proof tooling comprises a tooling frame 4, on which a plurality of mounting holes adapted to the main shaft 2 are arranged, after the main shaft 2 is inserted into the mounting holes from top to bottom, the lower surface of the striking part 3 is in contact and connected with the upper surface of the tooling frame 4, and the solid part of the upper surface of the tooling frame 4 completely covers the lower surface of the striking part 3 to form an anti-seepage structure.

[0022] When in use, the electric wrench part 1 (wrench shaft) to be carburized is sequentially inserted into the mounting hole of the fixture frame 4, and then placed in the carburizing equipment for carburizing process. During the carburizing process, since the upper surface of the fixture frame 4 is in contact with the lower surface of the striking part 3, the solid part of the upper surface of the fixture frame 4 protects the lower surface of the striking part 3, and the gas or liquid containing carbon element cannot contact the lower surface of the striking part 3, thereby preventing the lower surface of the striking part 3 from being carburized.

[0023] The main shaft 2 and the mounting hole are clearance-matched. Preferably, in order to ensure that the pull shaft can be stably placed on the fixture frame 4 after the main shaft 2 is inserted and installed, the clearance between the main shaft 2 and the mounting hole is a small clearance for smoothly inserting the main shaft 2.

[0024] In this embodiment, the upper end of the main shaft 2 forms an expanded pull shaft head 5, the striking portion 3 is arranged on both sides of the pull shaft head 5, a step structure is formed between the pull shaft head 5 and the main shaft 2, and the step structure forms an axial limit structure after the main shaft 2 is inserted into the mounting hole, and the lower surface of the pull shaft head 5 is in contact with the upper surface of the tooling frame 4 to form an anti-seepage structure. The above structure can further prevent carburization of the lower surface of the pull shaft head 5 to retain its toughness.

[0025] Compare with Figure 1The tooling frame 4 is a mesh plate structure, including a plurality of horizontal bars and vertical bars arranged at intervals, and the mounting holes are arranged at the intersections of the horizontal bars and the vertical bars, and each tooling frame 4 can hold a plurality of electric wrench parts 1 to be carburized. Preferably, the horizontal bars and the vertical bars have the same width, and preferably, the mounting hole is arranged in the center.

[0026] The width of the horizontal and vertical strips is greater than the width of the striking part 3 to ensure that the solid part of the upper surface of the fixture 4 can completely cover the lower surface of the striking part 3. Furthermore, the width of the horizontal and vertical strips is greater than the radial dimension of the head of the spindle 2.

[0027] In order to improve the carburizing efficiency, the anti-seepage tooling includes a multi-layer tooling frame 4, which includes a plurality of columns 6. The columns 6 are upright, and the tooling frame 4 is fixed on the columns 6 at horizontal intervals. Each layer of the tooling frame 4 is plugged with a plurality of electric wrench parts 1.

[0028] The spacing structure of the multi-layer tooling racks 4 is as follows: spacers 7 are arranged between adjacent tooling racks 4, and the tooling racks 4 and the spacers 7 are sequentially sleeved on the columns 6. Preferably, the same spacers 7 are arranged on each column 6.

[0029] In order to save axial space to place more electric wrench parts 1 to be carburized and improve the carburizing efficiency, the electric wrench parts 1 between adjacent tooling racks 4 are staggered.
