Drill jig for machining metal parts

Abstract

The utility model discloses a drill jig for processing metal parts, which comprises a bottom plate, two hollow plates are arranged above the bottom plate, a plurality of air ports are arranged on the two hollow plates, filter screens are arranged on the air ports, a circulating fan is mounted at the upper end of the bottom plate, and a plurality of air outlets are arranged on the circulating fan. The air outlet end of the circulating fan communicates with the interior of the hollow plate located on the right side through a hose. After the circulating fan is started, dust generated in the drilling process can be blown off through air flow blown out of the multiple air openings in the right side, meanwhile, due to the fact that air is sucked by the multiple air openings in the left side, leftward air flow is generated, the blown-off dust can pass through the hollow plate located on the left side, and the dust is prevented from being blown off. And the dust is finally sucked into the collecting box through the hose and is filtered by the filtering plate in the collecting box, cleaning is completed, the situation that the dust spreads in the air during drilling is avoided, and the health of operators is protected.

Description

Technical Field

[0001] The present application relates to the field of drilling machine fixture technology, and in particular to a drilling machine fixture used for metal parts processing. Background Art

[0002] Drilling machine fixtures are a type of fixture that is widely used in mechanical processing. The position accuracy of the processed holes is affected by many factors, and tool error is one of the influencing factors. In order to meet the requirements of the position accuracy of the holes of the processed parts, people have long used the extreme value method to calculate the tool error. However, when using the extreme value method for calculation, the assumed limit state rarely occurs in part processing, resulting in increased manufacturing accuracy and cost of the fixture;

[0003] With respect to the above-mentioned related technologies, the inventor believes that in the process of metal parts processing, the drilling machine fixture is an important tool for fixing and positioning the workpiece, and its performance directly affects the processing quality and efficiency. Although the common drilling machine fixtures on the market can meet the basic fixing and positioning requirements, they are obviously insufficient in handling the dust and debris generated during the processing. These dust and debris not only affect the processing accuracy of the workpiece, but also pollute the environment and even cause harm to the health of the operators;

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field.

This application provides a drill press fixture for metal parts processing.

[0006] The present application provides a drilling machine fixture for metal parts processing using the following technical solution:

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The present application embodiment discloses a drilling machine fixture for metal parts processing. Figure 1-2 A drilling machine fixture for metal parts processing includes a base plate 1, two hollow plates 10 are arranged above the base plate 1, multiple air outlets 14 are arranged on the two hollow plates 10, and filters are arranged on the multiple air outlets 14. A circulating fan 8 is installed on the upper end of the base plate 1, and the air outlet end of the circulating fan 8 is connected with the inside of the hollow plate 10 located on the right side through a hose. A cleaning mechanism and a limiting mechanism for the drilling machine fixture are arranged on the base plate 1.

[0022] Reference Figure 2 The cleaning mechanism includes a collecting box 15 arranged at the upper end of the bottom plate 1, a filter plate is arranged in the collecting box 15, the suction end of the circulating fan 8 extends into the collecting box 15, and the collecting box 15 is connected to the interior of the hollow plate 10 located on the left side through a hose.

[0023] After the circulating fan 8 is started, it will blow out air through the multiple air vents 14 on the right side to blow away the dust generated during the drilling process. At the same time, due to the air suction at the multiple air vents 14 on the left side, a leftward airflow is generated, which can pass the blown dust through the hollow plate 10 on the left side and finally be sucked into the collection box 15 through the hose, and filtered by the filter plate in the collection box 15 to complete the cleaning, thereby avoiding the situation where dust is diffused in the air during drilling and protecting the health of the operating workers.

[0024] Reference Figure 2-3 The limiting mechanism includes a motor 3 installed on the left outer wall of the base plate 1. A slide groove 11 is opened in the base plate 1. A bidirectional threaded rod 13 is rotatably connected between the left and right inner walls of the slide groove 11. Two sliders 12 are threadedly connected to the bidirectional threaded rod 13. The two sliders 12 are slidably connected to the front and rear inner walls of the slide groove 11. The upper ends of the two sliders 12 are fixedly connected to the limiting plates 9, and the upper ends of the two limiting plates 9 are fixedly connected to the lower ends of the corresponding hollow plates 10.

[0025] After the motor 3 is started, the bidirectional threaded rod 13 rotates, and then the two sliders 12 threadedly connected thereto drive the corresponding limit plates 9 to move relatively, fixing the two ends of the metal part, so that the device can adapt to more metal parts of different sizes.

[0026] Reference Figure 1-2 The output shaft end of the motor 3 extends into the slide groove 11 and is fixedly connected to one end of the bidirectional threaded rod 13. A control switch 2 is installed on the left side of the base plate 1. The control switch 2 is connected to the motor 3 and the circulating fan 8 by signal. The model of the motor 3 can be selected as YE2-6344-37KW. Two electric telescopic rods 4 are symmetrically installed on the upper end of the base plate 1. The telescopic ends of the two electric telescopic rods 4 are fixedly connected to a top plate 5. The lower end of the top plate 5 is fixedly connected to a vertical rod 6. The lower end of the vertical rod 6 is provided with a drilling machine assembly 7.

[0027] The implementation principle of a drilling machine fixture for metal parts processing in the embodiment of the present application is as follows: when in use, the metal parts to be processed are placed on the upper end of the bottom plate 1, between the two limit plates 9, and then the motor 3 is started by the control switch 2. After the motor 3 is started, the bidirectional threaded rod 13 rotates, and then the two sliders 12 threadedly connected thereto drive the corresponding limit plates 9 to move relatively, and the two ends of the metal parts are fixed, so that the device can adapt to more metal parts of different sizes, and then the top plate 5 and the drilling machine assembly 7 can be driven downward by starting the two electric telescopic rods 4 to perform drilling work;

[0028] In the above process, the circulating fan 8 is started by controlling the switch 2. After the circulating fan 8 is started, airflow will be blown out through the multiple air vents 14 on the right side to blow off the dust generated during the drilling process. At the same time, due to the air suction at the multiple air vents 14 on the left side, a leftward airflow is generated, which can pass the blown dust through the hollow plate 10 on the left side and finally be sucked into the collection box 15 through the hose, and filtered by the filter plate in the collection box 15 to complete the cleaning, thereby avoiding the situation where dust is diffused in the air during drilling and protecting the health of the operating workers.
