Problems solved by technology
[0002] When processing the workpiece, it needs to be clamped and positioned. For special-shaped components, a bayonet that fits its geometric shape is required. If a general-purpose clamp is used, the clamping will not be fastened and the components will be easily damaged.
For some special workpieces, such as G-type workpieces, if only a general-purpose down-pressing fixture is used, the front and rear wall panels of the G-type workpiece will not have a clamping effect, nor will they have an anti-seismic effect, resulting in the workpiece being damaged. The processing accuracy is low, and it is easy to deform the front wall and the rear wall, which reduces the qualified rate of the product and causes waste

Embodiment Construction
[0033] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0034] A special fixture for G-shaped workpieces, which is used for clamping workpieces with a G-shaped vertical section, including a base base beam 1, a front reference plate 2, an upper reference plate 3, a front clamping device 4, and a rear clamping device 5 and the upper pressing device 6; the section of the reference bottom beam 1 is square;
[0035] The front side reference plate 2 is arranged on the side of the reference bottom beam 1, and is perpendicular to the reference bottom beam 1. The front side reference plate 2 is provided with an escape hole 21, and the escape hole 21 is used to avoid the position where the front wall plate 01 of the G-shaped workpiece needs to be processed;
[0036] One side of the upper reference plate 3 is fixed on the upper end surface of the front reference p...

The invention discloses a clamp special for a G-shaped workpiece and a using method thereof. The clamp is used for clamping the workpiece with a G-shaped vertical section. The workpiece with the G-shaped section is formed by bending a front wallboard, a bottom wallboard, a rear wallboard and a top wallboard in sequence. The clamp comprises a datum bottom beam, a front datum plate, an upper datum plate, a front pressing device, a rear pressing device and an upper pressing device. The G-shaped workpiece is positioned and pressed from the front side, the rear side and the upper side by means of the clamp, so that the G-shaped workpiece is clamped more stably. According to the clamp special for the G-shaped workpiece, clamping and positioning are conducted according to the G-shaped structural design of the workpiece, and the clamping effect is good; meanwhile, shock resistance is high, and workpiece machining precision is improved. By the adoption of the using method, workpiece clamping stability can be ensured, and deformation of the workpiece can be avoided.
Description
technical field [0001] The invention relates to the technical field of fixtures, in particular to a special fixture for G-shaped workpieces and a method for using the same. Background technique [0002] When processing the workpiece, it needs to be clamped and positioned. For special-shaped components, a bayonet that fits with its geometric shape is required. If a general-purpose clamp is used, the clamping will not be fastened and the components will be easily damaged. For some special workpieces, such as G-type workpieces, if only a general-purpose down-pressing fixture is used, the front and rear wall panels of the G-type workpiece will not have a clamping effect, nor will they have an anti-seismic effect, resulting in the workpiece being damaged. The processing precision is low, and it is easy to deform the front wall board and the rear wall board, which reduces the qualified rate of the product and causes waste. Contents of the invention [0003] The purpose of the p...
