Problems solved by technology

[0002] At present, the tooling fixtures used for product processing can basically only clamp one station and process one process. In this way, multiple sets of tooling need to be invested in multi-tooling and multi-station processing, and multiple clamping installations are required during processing, which is not conducive to saving tooling. cost, and the processing time cannot be simplified; in order to solve this problem, it is generally necessary to install additionally purchased indexing equipment (such as a dividing head) to achieve indexing processing (multiple stations can be clamped at one time, and multiple processes can be processed). However, the purchased indexing mechanism increases the cost of purchasing indexing equipment

Embodiment 1

[0031] Such as figure 1 combine image 3 , Figure 4 , Figure 5 Shown, a kind of multi-station rotary drilling mold, it comprises:

[0032] Drilling template body 1, which is fixed on the external device;

[0033] Rotary positioning plate 2 is used to fix the workpiece to be processed, and the rotary positioning plate 2 is installed on the drilling template body 1 and rotates around the installation place;

[0034] The movable locating pin 3 is installed on the template body 1 to locate / resolve the rotating locating plate 2 .

[0035] In this way, when the workpiece to be processed needs to be processed, the drill template body is first fixed on the external device (or under the drill bit), and then the workpiece to be processed is fixed on the rotary positioning plate 2, and the rotary positioning plate 2 is rotated to achieve processing After the position, use the movable positioning pin 3 to locate the rotary positioning plate 2, like this, just can carry out the firs...

Embodiment 2

[0049] As described above, the difference between this embodiment and the multi-station rotary drilling mold is that, in combination with figure 2 As shown, the rotary positioning plate 2 includes: a rotary positioning disc 21 and a rotating main board 22, the rotary positioning disc 21 is rotatably mounted on the drill template body 1, and an indexing groove (not shown in the figure) is arranged on it. ); the rotating main plate 22 is connected with the rotating positioning plate 21, and rotates with the rotation of the rotating positioning plate 21. The rotating positioning plate 21 and the rotating main board 22 are detachable.

[0050] In this way, once the indexing groove is worn out, it is convenient to replace the rotary positioning disc 21 (in the process of use, the indexing slot is used frequently and requires high precision, and is easy to wear), and only the rotary positioning disc needs to be replaced, saving Material.

[0051] One end of the central protrusion...

Embodiment 3

[0066] As described above, the difference between this embodiment and the multi-station rotary drilling mold is that, in combination with Figure 6 As shown, when using the multi-station rotary drilling jig, the workpiece to be processed needs to be fixed and then processed. In order to ensure the accuracy of processing, the workpiece to be processed needs to be fixed at an accurate position, that is, the end face of the workpiece to be processed and the Fixed end face fit; in this multi-station rotary drilling mold, it is fixed by two compression bolts. If one of them is not tightened or the position is not accurate, the fixed position of the workpiece to be processed will be offset, so that Machining accuracy is greatly reduced.

[0067] There is an end face on the backing plate 23 (rotation positioning plate 2), and this end face fits with the end face of the workpiece to be processed and a plurality of pressure sensors 28 are arranged on the end face, and the backing plate...

Abstract

The invention discloses a multi-station rotary drilling jig, comprising a drilling jig body, a rotary locating plate and a movable locating pin, wherein the drilling jig body is fixed on an external device; the rotary locating plate is used for fixing a to-be-processed workpiece, is arranged on the drilling jig body, and rotates around a mounting position; and the movable locating pin is arranged on the drilling jig body and is used for locating / un-locating the rotary locating plate. Therefore, a dividing apparatus does not need to be additionally arranged, multiple stations can be clamped once to perform multiple processing steps, the use is simple, and the processing is convenient; and meanwhile, by use of the multi-station rotary drilling jig, the processing of multiple processing steps can be performed by one-step mounting, the processing time is shortened, and multiple sets of fixtures are not needed in use or the dividing apparatus does not need to be additionally purchased, so that the cost for the fixtures and the dividing apparatus is saved.

Description

technical field [0001] The invention relates to the technical field of fixture design, in particular to a multi-station rotary drilling mold. Background technique [0002] At present, the tooling fixtures used for product processing can basically only clamp one station and process one process. In this way, multiple sets of tooling need to be invested in multi-tooling and multi-station processing, and multiple clamping installations are required during processing, which is not conducive to saving tooling. cost, and the processing time cannot be simplified; in order to solve this problem, it is generally necessary to install additionally purchased indexing equipment (such as a dividing head) to achieve indexing processing (multiple stations can be clamped at one time, and multiple processes can be processed). But adopting the indexing mechanism purchased increases the cost of purchasing indexing equipment. [0003] In view of the above-mentioned defects, the creator of the pr...
