Description

Technical Field

[0001] The utility model relates to the technical field of drilling fixtures, in particular to a drilling device for a base plate frame. Background Art

[0002] The base plate frame is an indispensable part in machinery and equipment. During the drilling process of the existing base plate frame, since most of the workpieces are special-shaped (unconventional shapes) and the fixation is complicated, in most cases, it is impossible to use a general fixture for clamping, and a specific special fixture is required for drilling. The base plate frame not only needs to be placed horizontally to process horizontal holes, but also needs to be placed vertically to process vertical holes. The drilling fixture of the traditional base plate frame has low workpiece fixing efficiency and unreliable positioning, especially in the process of vertical placement to process vertical holes, the drilling swing amplitude is large and the drilling accuracy is poor. Therefore, further optimization is urgently needed. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 3The bottom plate frame has an L-shaped drilling frame 1, and the L-shaped drilling frame 1 includes a bottom frame 2 and a backing bracket 3. A drilling template 4 is lifted and lowered on the backing bracket 3, and a drilling template sleeve 5 is detachably provided on the drilling template 4. A first backing component 6 and a second backing component 7 are detachably provided on the backing bracket 3. A clamping bracket 8 is provided on the bottom frame 2, and a clamping component 9 is provided on the clamping bracket 8. The clamping component 9 is arranged between the first backing component 6 and the second backing component 7. When the bottom plate frame processes the horizontal hole position, the drilling template 4 moves up and down with the drilling template sleeve 5 on the backing bracket 3. At the same time, the backing component 6 and the backing component 7 are also moved down in sequence and installed on the installation hole position at the lower end of the backing bracket 3. When the bottom plate frame processes the vertical hole position, the drilling template 4 can be raised in the opposite direction. The positioning method using two backing components and a clamping component has low cost and good economy, and greatly reduces the swing amplitude of the drilling hole, and has reliable positioning and stable processing.

[0020] The first backrest component 6 includes a first backrest block 61 and a first backrest screw 62, the first backrest screw 62 passes through the backrest bracket 3 and is fixed on the first backrest block 61, the second backrest component 7 includes a second backrest block 71 and a second backrest screw 72, the second backrest screw 72 passes through the backrest bracket 3 and is fixed on the second backrest block 71, and the backrest bracket 3 is evenly provided with installation positioning holes for the backrest screws to realize the adjustment of different backrest positions to improve adaptability.

It has a simple structure and a large clamping stroke. It has two major characteristics: a large force amplification ratio and good self-locking performance. In order to reduce the time (auxiliary time) for clamping and loosening the workpiece, a quick-loading and unloading spiral clamping mechanism is used, and manual clamping is performed quickly. By adjusting the clamping handle 93, a reliable clamping force can be specified.
