Description

Technical Field

[0001] This utility model relates to the technical field of automatic drilling and tapping machines, and in particular to a multifunctional automatic drilling and tapping machine. Background Technology

[0002] A drilling and tapping machine is a metal cutting machine tool, similar in style and function to a machining center, but smaller. Although it can perform boring and milling operations, it cannot perform heavy-duty operations such as heavy-duty milling. It is mainly used for drilling and tapping, and is mainly used in the fields of electronics, machinery, automobiles, and aerospace. Especially in mass production, it can greatly improve production efficiency and processing quality.

[0003] The existing technology has the following defects or problems: The existing technology disclosed in CN213053844U is a drilling and tapping machine with automatic positioning function, which relates to the field of drilling and tapping technology. Specifically, it includes a base plate, a number of support legs are fixedly connected to the lower surface of the base plate, a processing table is fixedly connected to the upper surface of the base plate through a number of support rods, an air suction hood is fixedly connected to the upper surface of the processing table, a fan is installed on the upper surface of the base plate, and the inlet of the fan is fixedly connected to the air suction hood through an exhaust pipe.

[0004] During use, the aforementioned equipment, through its horizontal and vertical adjustment mechanisms, enables the drill bit to automatically feed and position itself horizontally and longitudinally. The controller activates the hydraulic cylinder, causing the drill-tapping motor and the drill bit mounted at the output end to move downwards for processing. This avoids excessive deviation in the drill-tapping position caused by manual operation errors, reduces the labor intensity of workers, and improves the quality and efficiency of workpiece processing.

[0005] The drilling and tapping machine structure described above does not have a fixed structure for machining workpieces. It is generally fixed manually. This operation is prone to errors due to improper manual clamping and is not convenient for machining workpieces of different specifications and shapes. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that when there is no fixed structure for processing workpieces, manual assistance is generally required for fixing. This operation is prone to errors due to improper manual clamping and is not convenient for processing workpieces of different specifications and shapes. In order to solve the above problems, a multi-functional automatic drilling and tapping machine is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: It includes a device frame; a longitudinal translation mechanism is provided inside the device frame; a drilling platform is provided on the upper part of the longitudinal translation mechanism; a fixed frame is fixedly connected to the upper surface of the drilling platform; an electric push rod is fixedly connected inside the fixed frame; a slider is fixedly connected to the output end of the electric push rod; a first connecting shaft is symmetrically rotatably connected to the upper surface of the slider; a support rod is fixedly connected inside the fixed frame; a connecting block is symmetrically slidably connected to the outer surface of the support rod; a second connecting shaft is rotatably connected to the outer surface of the connecting block; a rotating rod is rotatably connected between the second connecting shaft and the first connecting shaft; a support plate is fixedly connected to the upper surface of the connecting block; and a clamping block is fixedly connected to the inner side of the support plate.

[0008] In practical applications, the electric push rod pushes the slider to slide along the fixed rod. When the slider moves, it drives the first connecting shaft to rotate the rod, so that the rotating rod pulls the connecting block to slide symmetrically along the support rod through the second connecting shaft. The connecting block drives the support plate and the clamping block to move synchronously.

[0009] Furthermore, the clamping block has a first limiting groove symmetrically opened inside, a first movable block is rotatably connected inside the clamping block, a first limiting ring is fixedly connected to the outside of the first movable block, and the first limiting ring is rotatably connected inside the first limiting groove.

[0010] In practical applications, the first movable block can rotate around the clamping block and be limited within the first limiting groove by the first limiting ring.

[0011] Furthermore, the first movable block has a second limiting groove symmetrically opened inside, the first movable block is rotatably connected to the second movable block, the second movable block is fixedly connected to the outside of the second movable block, and the second limiting ring is rotatably connected inside the second limiting groove.

[0012] In practical applications, the second movable block can rotate around the first movable block and be limited in the second limiting groove by the second limiting ring until it fits the surface of the workpiece.

[0013] Furthermore, a locking block is provided on the front side of the second movable block. The locking block has several anti-slip structures on its outside. The locking block is screwed into the threaded hole at the front end of the second movable block by a threaded connection. When tightened, its end face presses against the corresponding surface of the first movable block, and the angle is fixed by friction.

[0014] In practical applications, the angle is fixed by the locking block, and its external anti-slip structure enhances clamping stability and prevents workpiece displacement.

[0015] Furthermore, a lifting mechanism is provided inside the device frame, a drilling mechanism is provided outside the lifting mechanism, and a control panel is fixedly connected to the outside of the device frame.

[0016] In practical applications, the control panel controls the longitudinal translation mechanism to drive the drilling and tapping table and the workpiece to move longitudinally, while simultaneously controlling the lifting mechanism to adjust the height of the drilling and tapping mechanism.

[0017] Furthermore, a collection groove is provided on the upper surface of the drilling platform, which is used to collect impurities generated after drilling.

[0018] In practical applications, impurities generated during the drilling process fall directly into the collection groove opened on the surface of the drilling platform.

[0019] Furthermore, a fixing rod is fixedly connected inside the fixing frame, and the upper surface of the fixing rod is slidably connected to the lower surface of the slider.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By setting a clamping block above the drilling table of the device, the workpiece can be kept in a fixed position during the processing, reducing processing errors caused by workpiece movement or vibration, thereby improving processing accuracy;

[0022] Second, by flexibly setting the clamping blocks, it is possible to effectively clamp and fix different types of workpieces according to their shapes, thereby expanding the equipment's adaptability to various irregular and non-standard parts. Multiple workpieces can be processed without frequent fixture changes, significantly improving the changeover efficiency on the production line and reducing the time and labor costs caused by fixture changes.

A control panel 23 is fixedly connected to the outside of the device frame 1. A collection groove 24 is opened on the upper surface of the drilling table 3. The collection groove 24 is used to collect impurities generated after drilling. A fixing rod 25 is fixedly connected inside the fixing frame 4. The upper surface of the fixing rod 25 is slidably connected to the lower surface of the slider 6.

[0032] In practical applications, the device is started via the control panel 23. The electric push rod 5 pushes the slider 6 to slide along the fixed rod 25. When the slider 6 moves, it drives the first connecting shaft 7 to rotate the rod 11, so that the rotating rod 11 pulls the connecting block 9 to slide symmetrically along the support rod 8 via the second connecting shaft 10. The connecting block 9 drives the support plate 12 and the clamping block 13 to move synchronously, so as to achieve the initial clamping of the workpiece.

[0033] After clamping is completed, the control panel 23 controls the longitudinal translation mechanism 2 to drive the drilling and tapping table 3 and the workpiece to move longitudinally, and at the same time controls the lifting mechanism 21 to adjust the height of the drilling and tapping mechanism 22. The drilling and tapping mechanism 22 is started to perform drilling and tapping on the workpiece.

[0034] Impurities generated during the drilling process fall directly into the collection groove 24 opened on the upper surface of the drilling platform 3, realizing the centralized collection of impurities and facilitating subsequent cleaning.
