Description

Technical Field

[0001] This invention belongs to the field of mechanical cutting processing technology, specifically relating to a machining fixture for radial holes in hollow prism-type parts, and more particularly to a positioning drilling jig device for machining radial holes in prism-type parts. Background Technology

[0002] The company produces over 1000 heaters annually, each containing a hexagonal threaded insert with a radial through hole. To ensure the machining accuracy of the radial hole in the hexagonal threaded insert, in actual machining, a fitter typically needs to manually mark the hole's position line on the outer surface of the insert before drilling using a bench drill. This traditional machining method is not only costly but also inefficient, making it difficult to meet the demands of mass production. To solve this problem, a dedicated positioning drilling jig device is urgently needed. Summary of the Invention

[0003] The purpose of this invention is to provide a positioning drilling jig device for machining radial holes in prism-shaped parts, so as to achieve rapid and accurate clamping of hexagonal threaded inserts, stably ensure the positional accuracy and machining quality of the radial holes, and at the same time improve machining efficiency and reduce machining costs. To achieve the above objectives, this invention adopts the following technical solution: a positioning drilling jig device for machining radial holes in prism-shaped parts, employing a complete positioning method combining an internal hexagonal positioning groove and an end face stop. The device includes a drilling template, an internal hexagonal positioning base, and an end face stop. When drilling using this device, the end face stop is first embedded in one end of the groove in the internal hexagonal positioning base to restrict the axial movement of the hexagonal threaded insert; then, one end of the hexagonal threaded insert to be machined is pushed axially into the groove from the other end of the internal hexagonal positioning base, so that its end face abuts against the end face stop; the drilling template is installed on the open side of the internal hexagonal positioning base, and the lower end face of the drilling template is in contact with the surface of the hexagonal threaded insert to be machined. After the entire device is assembled, it is clamped and fixed on the worktable of the drilling machine, and then the radial drilling operation of the hexagonal threaded sleeve can be performed.

[0004] The beneficial effects of this invention are as follows:

[0005] 1) High positioning accuracy and stable processing quality: No manual scribing or repeated alignment is required, which can accurately guarantee the axial position dimension of the radial hole and ensure good dimensional consistency in batch processing;

[0006] 2) High clamping efficiency and short processing cycle: The pre-processing steps of scribing and alignment by fitter are eliminated, which greatly shortens the auxiliary time for single-piece processing and significantly improves the processing efficiency of batch production.

[0007] 3) Low production cost and strong equipment adaptability: The device has a simple overall structure and is easy to manufacture and process. It can be directly adapted to ordinary bench drills, which reduces the dependence on the skill level of operators, reduces the scrap loss caused by human operation errors, and effectively controls the processing cost of a single piece.

[0010] A drilling jig device for locating radial holes in prism-type parts includes a drilling template (1), an internal hexagonal locating base (2), and an end face block (3). The internal hexagonal locating base (2) has an internal hexagonal locating groove that matches the outer contour of the hexagonal threaded sleeve (4) to be processed. The end face block (3) is embedded in one end of the groove of the internal hexagonal locating base (2) to restrict the axial movement of the hexagonal threaded sleeve (4) to be processed. The drilling template (1) is installed on the open side of the internal hexagonal locating base (2), and the lower end face of the drilling template (1) is in contact with the surface to be processed of the hexagonal threaded sleeve (4).

[0011] The drill template (1) has guide holes that correspond one-to-one with the radial holes of the hexagonal threaded sleeve (4) to be processed, which are used to guide the drill bit to complete the drilling operation along the set position.

[0012] One end of the hexagonal threaded sleeve (4) to be processed is pushed axially into the internal hexagonal positioning groove from the other end of the internal hexagonal positioning base (2), and its end face abuts against the end face stop (3).

[0013] After the drill template (1) and the internal hexagonal positioning base (2) are assembled, they are clamped and fixed on the worktable of the drill press.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1As shown, this embodiment provides a drilling jig device for locating radial holes in prism-shaped parts, including a drilling template (1), an internal hexagonal locating base (2), and an end face block (3). The internal hexagonal locating base (2) has an internal hexagonal locating groove that matches the outer contour of the hexagonal threaded sleeve (4) to be processed, which is used to achieve precise radial and axial positioning of the workpiece. In actual processing, the end face block (3) is first installed in the groove at one end of the internal hexagonal locating base (2) as an axial limiting reference. Then, one end of the hexagonal threaded sleeve (4) to be processed is pushed axially into the groove from the other end of the internal hexagonal locating base (2) until its end face is completely against the end face block (3). Next, the drilling template (1) is installed on the open side of the internal hexagonal locating base (2) to ensure that the lower end face of the drilling template (1) is in close contact with the surface to be processed of the hexagonal threaded sleeve (4). The drill template (1) has guide holes that correspond one-to-one with the holes of the hexagonal threaded sleeve (4) to be machined, which are used to guide the drill bit to complete the drilling operation along the set position. After the entire device is assembled, it is clamped and fixed on the worktable of the drilling machine, and the radial drilling operation of the hexagonal threaded sleeve can be performed directly. This device completely eliminates the traditional manual scribing process, which not only ensures the machining accuracy, but also greatly improves the efficiency of mass production. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
