General-purpose device for machining parts with locating pin holes.

Abstract

This utility model discloses a universal device for processing parts with locating pin holes, including a fixed base, on which a first locating pin is fixedly disposed. A sliding groove is provided on the fixed base, and a slider is slidably disposed within the groove. A second locating pin is fixedly disposed on the slider. As the slider slides along the groove, the distance between the first and second locating pins changes. This device employs two-pin positioning: one pin is fixed, and the other is fixed to the slider and slides along the groove with it. This allows for positioning of different parts at different distances between the two pins. This structure enables rapid and accurate positioning of different parts while ensuring reliable part positioning. For multi-variety, small-batch workpieces, it allows for rapid switching between processing methods and can continuously and stably guarantee processing quality, significantly saving on the cost of special tooling manufacturing and workpiece alignment and clamping time, effectively reducing the processing cost of parts.

Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a general-purpose device for machining parts with locating pin holes. Background Technology

[0002] When machining and manufacturing parts, we often encounter seat-type parts with locating pin holes, and the top hole of the part has a positional relationship with the pin hole. In order to ensure the technical accuracy requirements of the part machining, different locating fixtures need to be made according to the pin hole position of different types of parts. This results in high fixture manufacturing costs, high part machining costs, and frequent alignment and clamping when switching workpieces, which is time-consuming and wasteful of materials. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a general-purpose device for processing parts with positioning pin holes, which facilitates rapid switching processing of multiple varieties of small batch workpieces and saves tooling manufacturing costs.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a general-purpose device for processing parts with positioning pin holes, including a fixed base, a first positioning pin fixedly disposed on the fixed base, a sliding groove disposed on the fixed base, a slider slidably disposed in the sliding groove, and a second positioning pin fixedly disposed on the slider; when the slider slides along the sliding groove, the distance between the first positioning pin and the second positioning pin changes.

[0005] As a preferred technical solution, the two sides of the slider that contact the groove are inclined surfaces.

[0006] As a preferred technical solution, the inclination angle of the inclined plane relative to the vertical plane is 2 to 3°.

[0007] As a preferred technical solution, the fixed seat is fixed on the worktable by a positioning key and a first T-nut.

[0008] As a preferred technical solution, a clamping mechanism is also included, which includes a pressure plate, a pad, and a clamping rod. The bottom end of the clamping rod is locked in the T-slot of the worktable by a second T-nut, and the top end of the clamping rod is connected to the pressure plate.

[0009] Due to the adoption of the above technical solution, this utility model has at least the following beneficial effects: This device adopts two-pin positioning, one pin is a fixed pin, and the other pin is fixed on the slider and slides along the slide groove with the slider, realizing positioning of different parts at different distances between the two pins. Both sides of the slider are inclined surfaces that fit tightly with the slide groove. After the part is positioned, the positioning will not be unstable due to the gap between the slider and the slide groove. This structure will enable the part to be positioned quickly and accurately on a general-purpose device, fully ensuring the reliability of the part positioning. For multi-variety small-batch workpieces, it can realize rapid switching processing and continuously and stably guarantee the processing quality, greatly saving the manufacturing cost of special tooling and the time cost of workpiece alignment and clamping, effectively reducing the processing cost of parts.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0017] like Figures 1 to 4As shown, a general-purpose device for processing parts with locating pin holes includes a fixed base 10 and a clamping mechanism 20. A first locating pin 11 is fixedly disposed on the fixed base 10, and a slide groove 12 is provided on the fixed base 10. A slider 13 is slidably disposed in the slide groove 12, and a second locating pin 14 is fixedly disposed on the slider 13. By sliding the slider 13 along the slide groove 12, the distance between the first locating pin 11 and the second locating pin 14 can be changed, thereby enabling positioning of different distances between the two pin holes of different parts.

[0018] refer to Figure 3 The two sides of the slider 13 that contact the slide groove 12 are preferably inclined surfaces. The angle α of the inclined surface relative to the vertical plane is preferably 2 to 3°. In this way, both sides of the slider 13 are inclined surfaces that fit tightly with the slide groove 12, and the positioning will not be unstable due to the gap between the slider 13 and the slide groove 12 after the part is positioned.

[0019] refer to Figure 1 and Figure 2 The clamping mechanism 20 includes a pressure plate 21, a pad 22, and a clamping rod 23. The bottom end of the clamping rod 23 is locked in the T-slot of the worktable 30 by a second T-nut 24, and the top end of the clamping rod 23 is connected to the pressure plate 21. Depending on the size of the part, 2 to 3 sets of clamping mechanisms can be provided.

[0020] refer to Figure 5 When machining a part 40 with locating pin holes, the side with the pin holes is first machined. Then, the part 40 is placed on the fixed base 10, and the slider 13 is dragged to align the first locating pin 11 and the second locating pin 14 with the two pin holes on the part 40, achieving two-pin positioning on one side of the part 40 (the locating pins can be replaced according to the pin hole diameter of the workpiece). Then, the pressure plate 21, clamping rod 23, and pad 22 firmly fix the part 40 to the worktable 30, allowing for the machining of the top hole. The fixed base 10 is fixed to one corner of the worktable 30 by two locating keys 15 and the first T-nut 16, avoiding the need for re-alignment after each machining operation. This effectively ensures the machining accuracy requirements of the part and avoids the time wasted on repeated alignment. For multi-variety, small-batch workpieces, rapid switching between machining operations is possible, and continuous and stable machining quality can be guaranteed, significantly saving on the cost of special tooling manufacturing and workpiece alignment and clamping time, effectively reducing the machining cost of the parts.

[0021] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
