Embodiment 1

[0027] A new type of thin plate drilling jig, which consists of: base 1, vertical manual compression rod 8, stage 9, horizontal feed positioning lock 10, sliding guide rail 11, drill support mechanism includes: drill sleeve support frame 3, bracket Reinforcing rib 2, drill sleeve 4, and pressing device include: pressing horizontal plate 5, pressing arm 6, parallel linkage mechanism 7.

Embodiment 2

[0029] According to a new type of thin plate drilling jig described in Embodiment 1, the drill sleeve support frame 3 and the drill sleeve 4 are installed at the left position in the middle of the jig base 1, and a bracket rib 2 is provided on the left side to achieve reinforcement. It can reduce the processing error caused by vibration. The drill sleeve 4 is located on the upper side of the drill sleeve support frame 3 .

Embodiment 3

[0031] According to a new thin plate drilling jig described in Embodiment 1, there is a V-shaped groove 21 on the top of the carrier table 9, which can conveniently discharge tailings and chips from the bottom of the groove during drilling. The bottom is provided with an L-shaped guide rail block 12 and a dovetail guide rail block 13, which are located on the sliding guide rail and can slide forward and backward, and the front and rear positioning locking can be realized by the horizontal feed setting mechanism 10. Described sliding guide rail 11 is divided into left guide rail and right guide rail, and left guide rail is L guide rail 12, and right guide rail is dovetail guide rail 13.

Abstract

The invention relates to a novel thin plate drilling fixture which comprises a base (1), a perpendicular manual compressing rod (8), an object stage (9), a horizontal feeding positioning lock (10), asliding guiding rail (11), a drill bit supporting mechanism and a compressing device, wherein the drill bit supporting mechanism comprises a drill bush supporting frame (3), a supporting frame reinforcing rib (2) and a drill bush (4); and the compressing device comprises a compressing transverse plate (5), a compressing arm (6) and a parallel linkage mechanism (7). The novel thin plate drilling fixture is characterized in that through the sliding guiding rail, the forward-backward sliding and positioning operation can be achieved; through the horizontal feeding positioning lock, the forward-backward positioning and locking operation can be achieved; the sliding guiding rail consists of an L-shaped guiding rail body and a dovetail groove rail body, and has the advantages of being high in smoothness, high in stability, and easy to machine and mount; a reset spring is built in the parallel linkage mechanism, so that the pretension force is relatively high, the uniformity of the clamping force in the horizontal direction is facilitated, and the horizontal clamping of a thin plate is facilitated when a hole is drilled in the thin plate; and the area of the contact between the compressing transverse plate and the thin plate is large, so that warping folds produced during the thin plate machining process are greatly reduced.

Description

technical field [0001] The patent of the present invention relates to a new type of thin plate drilling jig. Background technique [0002] In recent years, the machining industry has developed rapidly towards small-batch customization, and the demand for high-quality thin-plate drilling is increasing day by day, which puts forward higher requirements for thin-plate drilling jigs. The existing thin plate drilling jig clamps unevenly, resulting in warping and wrinkles during thin plate processing. Based on the solution of the above problems, the patent of the present invention designs a new thin plate drilling jig. The fixture improves the existing tooling fixture for thin-plate workpieces to improve its versatility, ensure its drilling quality, and improve work efficiency, which has great popularization value. Contents of the invention [0003] The purpose of the patent of the present invention is to provide a new type of thin plate drilling fixture. The purpose of the pr...
