Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crankshaft production, in particular to an external circle cutting mechanism for crankshaft production. Background Art
[0002] The crankshaft is the most important component in the engine. It bears the force transmitted from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine. The crankshaft is subjected to the combined effects of the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, which makes the crankshaft subject to bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, work evenly and have good balance.
[0003] When crankshafts are produced, they need to be cut. However, the current cutting device lacks a debris collection structure during cutting, and the generated debris will fall onto the screw or bed below, making it difficult to clean these debris. In addition, some debris attached to the screw will also affect its operation, easily causing jamming and other phenomena, making subsequent cleaning very troublesome. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-Figure 3The utility model discloses an external cylindrical cutting mechanism for crankshaft production, comprising a slide box 1, a tool holder 2 and a chip collecting assembly 3. The tool holder 2 is fixedly mounted on the slide of the slide box 1, and a cutting tool 4 is inserted into the chip collecting assembly 3. The chip collecting assembly 3 and the cutting tool 4 are fixedly clamped on the tool holder 2 by bolts. The cutting tool 4 is installed in the chip collecting assembly 3, and then the chip collecting assembly 3 is clamped on the tool holder 2. Since the cutting tool 4 is wrapped in the chip collecting assembly 3, the chips generated during machining fall into the chip collecting assembly 3 and fall into the collection box 33 through the chip guide port 38, which is convenient for collecting the chips generated when cutting the crankshaft together, and can prevent the chips from falling on the screw rod and affecting its operation, which brings convenience to people's use.
[0019] The chip collection assembly 3 includes a bracket 31, a shielding cover 32 and a collection box 33. The bracket 31 is provided with a positioning groove 34, and the end of the bracket 31 is provided with a T-shaped slot 35. The end of the shielding cover 32 is provided with a T-shaped block 36, and is clamped with the bracket 31 through the T-shaped block 36 and the T-shaped slot 35. The lower part of the shielding cover 32 is provided with a placement bin 37, and the top of the placement bin 37 is provided with a chip guide port 38, and the collection box 33 is clamped in the placement bin 37.
[0020] Specifically, a socket 39 is provided between the positioning slot 34 and the bracket 31 , and the socket 39 is flush with the positioning slot 34 .
[0021] In this embodiment, the socket 39 is provided to facilitate the insertion of the cutting tool 4 into the positioning groove 34 .
[0022] Specifically, the tail of the cutting tool 4 is inserted into the positioning groove 34 from the insertion opening 39 , and the top of the cutting tool 4 is flush with the positioning groove 34 .
[0023] In this embodiment, the positioning groove 34 is used to play the role of positioning and supporting, and is convenient for clamping together with the cutting tool 4 on the tool holder 2.
[0024] Specifically, the positioning groove 34 is placed in the clamping groove of the tool holder 2 , and the bolt on the tool holder 2 is locked on the cutting tool 4 .
[0025] In this embodiment, when the chip collecting assembly 3 is clamped on the tool holder 2 , the positioning groove 34 is placed in the clamping groove of the tool holder 2 and is locked by the bolts on the tool holder 2 .
[0026] Specifically, the bracket 31 is L-shaped, and the upper portion of the shielding cover 32 is U-shaped.
[0027] In this embodiment, the chip collecting assembly 3 adopts a split design to facilitate the cutting process of the crankshaft.
[0028] Specifically, the collecting box 33 is located below the chip guide port 38 , and a handle 310 is provided on the collecting box 33 .
[0029] In this embodiment, the chips generated during machining fall into the chip collecting assembly 3 and fall into the collecting box 33 through the chip guide opening 38, so that the chips generated during the cutting of the crankshaft can be collected together.
[0030] When in use, the slide box 1 is the control box for the feed movement of the lathe, and it is equipped with a mechanism that converts the rotational movement of the optical rod and the lead screw into the linear movement of the tool holder 2. The longitudinal feed movement, transverse feed movement and rapid movement of the tool holder 2 are realized through the optical rod transmission, and the tool holder 2 is driven by the lead screw to make longitudinal linear movement for turning. The tool holder 2 is used to install the turning tool and drive the turning tool to make longitudinal, transverse or oblique movement. The cutting tool 4 is installed in the chip collection assembly 3, and then the chip collection assembly 3 is clamped on the tool holder 2. Since the cutting tool 4 is wrapped in the chip collection assembly 3, the debris generated during processing falls into the chip collection assembly 3 and falls into the collection box 33 through the chip guide port 38, which is convenient for collecting the debris generated when cutting the crankshaft, and can avoid the debris falling on the lead screw and affecting its operation.
[0031] To sum up, the external cylindrical cutting mechanism for crankshaft production installs the cutting tool 4 into the chip collecting assembly 3, and then clamps the chip collecting assembly 3 on the tool holder 2. Since the cutting tool 4 is wrapped in the chip collecting assembly 3, the debris generated during processing falls into the chip collecting assembly 3 and falls into the collection box 33 through the chip guide port 38, which makes it easy to collect the debris generated when cutting the crankshaft, and can avoid the debris falling on the screw rod and affecting its operation, which brings convenience to people's use.
