Problems solved by technology

[0003] Since there is a helical gear in the automotive cylindrical gear, the outer side of the gear has inclined teeth. When the punching hole is separated, the punching hole and the working head will be separated, so as to drive the outer gear and make it shift. In turn, the teeth at the upper end of the helical gear are in line-surface contact with the fixture, causing damage to the teeth and affecting later use

Embodiment 2

[0036] Example 2: Please refer to Figure 5-Figure 8 , the specific embodiments of the present invention are as follows:

[0037]The adaptable block 33c includes a block c1, an outer bump c2, a rubber block c3, and an outer edge plate c4. The outer bump c2 is arranged on both sides of the upper end of the block c1 and is an integrated structure. The rubber block c3 is embedded Installed on the inner side of the upper end of the block c1 and between the outer projections c2, the outer edge plate c4 is arranged on the inner side of the block c1 and is fixedly connected.

[0038] refer to Figure 6 The outer edge plate c4 includes a plate body c41, an edge plate c42, an inner block c43, a side sealing block c44, and an inner sealing strip c45. The edge plate c42 is arranged at the side end of the plate body c41 and is an integrated structure, so The inner clamping block c43 is fixed on the front end of the plate body c41 and welded to each other. The inner clamping block c43 is...

Abstract

The invention discloses a fixing clamp for automobile cylindrical gear forging. The fixing clamp for automobile cylindrical gear forging structurally comprises a disc, a cover plate, a clamping structure and an embedded disc, wherein the cover plate is horizontally installed at the upper end of the disc, the clamping structure is installed at the upper end of the disc in an embedded mode, and the embedded disc is arranged at the inner side of the cover plate and connected with the disc through bolts; and the clamping structure comprises an embedded block, a sliding way and a clamping block, the embedded block is embedded in the cover plate and connected with the disc in a clamped mode, the sliding way is arranged at the inner side of the upper end of the embedded block, and the clamping block is installed at the inner side of the sliding way in an embedded mode and movably connected. According to the invention, the clamping block is arranged at the upper end of the embedded block, so that the embedded block is better abutted against the outer side of a gear, and make better contact with the gaps among the teeth, the stress of the teeth is reduced, better supporting is achieved, and the teeth are prevented from being damaged; and an outer edge plate is arranged at the inner side of a block body, so that a gap between the block body and the gear is reduced, better supporting is achieved, and therefore stress limitation of the teeth is ensured, and completeness of the teeth is ensured.

Description

technical field [0001] The invention belongs to the field of forging, and in particular relates to a fixing fixture for forging of an automobile cylindrical gear. Background technique [0002] Automotive cylindrical gears are mainly cylindrical gears used for mechanical transmission in automobiles. In the use of these gears, they must cooperate with the shaft, so the shaft holes of the gears need to be processed to match the movement of the shaft, and then Punching is required, and the forging of cylindrical gears includes forging and stamping. When the gears need to be punched, a fixing fixture for forging of automotive cylindrical gears is required. However, the prior art has the following deficiencies: [0003] Since there is a helical gear in the automotive cylindrical gear, the outer side of the gear has inclined teeth. When the punching hole is separated, the punching hole and the working head will be separated, so as to drive the outer gear and make it shift. Further...
