Description

Technical Field

[0001] This utility model relates to the field of drilling and tapping technology, and in particular to a benchtop drilling and tapping machine with a water-cooling structure. Background Technology

[0002] Drilling machines are currently one of the most common machining equipment. Existing drilling machines mainly consist of a base, a column mounted on the base, a worktable for placing workpieces, and a spindle box. The spindle box includes a motor, a transmission mechanism, a spindle, and a drill bit mounted on the spindle. When the motor rotates, it drives the spindle to rotate through the transmission mechanism, thereby realizing the drilling of the workpiece.

[0003] During drilling operations, the drill bit rotates at high speed to cut metal, generating a large amount of heat instantly. Without effective cooling, the drill bit's cutting edge will wear down rapidly due to overheating, drastically reducing its durability. Frequent drill bit replacements will only increase time and material costs. At the same time, heat accumulates on the workpiece, causing thermal deformation and loss of dimensional accuracy. Open-type drip cooling is usually used to cool the drill bit.

[0004] However, traditional drilling and tapping machines struggle to quickly and accurately adapt to workpieces of different sizes and shapes. They often rely on the operator's experience to estimate and adjust, which can easily lead to uneven clamping force. During heavy drilling and tapping, the workpiece is prone to loosening and displacement, resulting in machining defects such as skewed drilling and broken tapping threads. This leads to a high scrap rate, increases production costs, and the open drip cooling system suffers from the drawbacks of wasting coolant by splashing and failing to apply it precisely to the machining area. It is also difficult to efficiently remove heat and flush away chips. Chip accumulation can scratch the workpiece and accelerate tool wear, creating a vicious cycle.

[0005] Therefore, a benchtop drilling and tapping machine with a water-cooled structure is provided to solve the problems mentioned in the background art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a benchtop drilling and tapping machine with a water-cooled structure. It aims to improve the existing technology, which is difficult to quickly and accurately adapt to workpieces of different sizes and shapes. It often relies on the operator's experience to estimate and adjust, which can easily lead to uneven clamping force. During heavy cutting in drilling and tapping, the workpiece is prone to loosening and displacement, resulting in machining defects such as drilling deviation and tapping thread damage. The scrap rate is high, which increases production costs. In addition, the open drip cooling has the disadvantages of wasting coolant by splashing and not being able to accurately act on the machining area. It is difficult to efficiently remove heat and flush away chips. The accumulation of chips will scratch the workpiece and aggravate tool wear, resulting in a vicious cycle.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a benchtop drilling and tapping machine with a water-cooled structure, comprising a base, a drilling and tapping machine body fixedly mounted on the upper side of the base, a support plate fixedly mounted on the drilling and tapping machine body, a clamping assembly provided on the support plate, and a water spraying assembly provided on the lower side of the support plate; the clamping assembly includes a clamping plate, the clamping plate is disposed on the upper side of the support plate, a connecting plate is fixedly connected to the outer side of the clamping plate, mounting bolts are fixedly mounted inside the connecting plate, and limit holes are formed inside the support plate.

[0008] Furthermore, the water spray assembly includes a water tank, which is fixedly installed on the upper side of the base. A filter screen is fixedly installed inside the water tank. A communication component is provided on the rear side of the water tank, and a limit component is provided on the front side of the communication component.

[0009] Furthermore, the connecting component includes a water pump, which is fixedly connected to the rear side of the water tank. A connecting hose is fixedly connected to the rear side of the water pump, and a nozzle is fixedly connected to the front side of the connecting hose.

[0010] Furthermore, the limiting component includes a fixing plate, which is fixedly installed on the drilling machine body. A limiting groove is formed inside the fixing plate, and a limiting block is fixedly connected to the outside of the nozzle.

[0011] Furthermore, the mounting bolt is threaded into the inside of the limiting hole.

[0012] Furthermore, the limiting block is slidably connected inside the limiting groove.

[0013] Furthermore, the support plate has several evenly distributed through holes inside.

[0014] Furthermore, a water outlet pipe is fixedly connected to the left side of the water tank.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, after the workpiece to be processed is placed stably on the side of the support plate, the position of the clamping plate is flexibly adjusted according to the actual size of the workpiece to adapt to different specifications. At this time, with the help of the mounting bolts on the connecting plate passing through the limiting holes, the operator only needs to tighten the mounting bolts. As the threads are gradually tightened in the limiting holes, the clamping plate is firmly fixed by the tight friction between the bolts and the hole wall, as well as the synergistic effect of the mutual squeezing between the related components. This effectively prevents displacement deviation during subsequent drilling operations and lays a solid foundation for high-precision processing.

[0017] In this invention, by starting the water pump, the water in the tank is forcefully drawn and flows along the connecting hose to the nozzle. The outer limiting block of the nozzle slides freely in the limiting groove of the fixed plate, ensuring the stability of the nozzle and adjusting the spray angle and position according to the preset trajectory. This ensures that the coolant is accurately sprayed onto the drilling and machining area. During machining, the coolant efficiently absorbs the huge amount of heat generated by the drill bit cutting, protecting the drill bit from thermal wear and the workpiece from thermal deformation. At the same time, with the help of the through holes in the support plate, the chips are swept away and flushed down, keeping the machining area clean and orderly at all times.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides: a benchtop drilling and tapping machine with a water-cooled structure, including a base 4, a drilling and tapping machine body 1 fixedly installed on the upper side of the base 4, a support plate 2 fixedly installed on the drilling and tapping machine body 1, a clamping assembly 3 provided on the support plate 2, and a water spraying assembly 5 provided on the lower side of the support plate 2; the clamping assembly 3 includes a clamping plate 31, the clamping plate 31 is located on the upper side of the support plate 2, a connecting plate 32 is fixedly connected to the outer side of the clamping plate 31, an installation bolt 33 is fixedly installed inside the connecting plate 32, and a limit hole 34 is opened inside the support plate 2.

[0027] During the workpiece preparation stage, the workpiece is placed on the upper side of the support plate 2, and the position of the clamping plate 31 is adjusted to fit the workpiece size. The mounting bolts 33 on the connecting plate 32 on the outer side of the clamping plate 31 pass through the limiting hole 34. By rotating the mounting bolts 33, they are tightened into the threads inside the limiting hole 34. Relying on the friction between the bolts and the hole wall and the mutual squeezing between the components, the clamping plate 31 can be firmly fixed, so that the workpiece is firmly clamped on the support plate 2, preventing displacement during subsequent drilling and tapping, and ensuring machining accuracy.

[0028] Reference Figure 1 , Figure 4 and Figure 5 The water spray assembly 5 includes a water tank 52, which is fixedly installed on the upper side of the base 4. A filter screen 51 is fixedly installed inside the water tank 52. A connecting assembly is provided on the rear side of the water tank 52, and a limiting assembly is provided on the front side of the connecting assembly. The connecting assembly includes a water pump 53, which is fixedly connected to the rear side of the water tank 52. A connecting hose 54 is fixedly connected to the rear side of the water pump 53, and a nozzle 55 is fixedly connected to the front side of the connecting hose 54. The limiting assembly includes a fixing plate 57, which is fixedly installed on the drilling machine body 1. A limiting groove 58 is opened inside the fixing plate 57, and a limiting block 56 is fixedly connected to the outer side of the nozzle 55. Several evenly distributed through holes 35 are opened inside the support plate 2.

[0029] During the processing, the water tank 52 serves as a water storage unit. The internal filter screen 51 filters out impurities in the water to prevent them from clogging the subsequent water path or damaging equipment components. After the water pump 53 is started, it draws water from the water tank 52. The water is then transmitted to the nozzle 55 via the connecting hose 54 connected to the rear. The limiting block 56 on the outer side of the nozzle 55 slides within the limiting groove 58 of the fixing plate 57, ensuring the stability of the nozzle 55 and allowing the spray angle and position to be adjusted according to the preset trajectory. This ensures that the coolant is accurately sprayed onto the drilling and processing area. During processing, the coolant carries away the heat generated by the high-speed rotation of the drill bit, preventing overheating and wear of the drill bit and affecting the accuracy of the workpiece due to thermal deformation. It also washes away the chips. With the help of several evenly distributed through holes 35 on the support plate 2, the chips and coolant fall together, keeping the processing area clean.

[0030] Reference Figure 1 , Figure 3 and Figure 5 The mounting bolt 33 is threaded into the inside of the limiting hole 34, the limiting block 56 is slidably connected into the inside of the limiting groove 58, and the water tank 52 is fixedly connected to the left side of the water outlet pipe 59.

[0031] By installing bolts 33 and threaded connection inside the limiting hole 34, the clamping plate 31 can be limited and fixed. By sliding the limiting block 56 inside the limiting groove 58, the nozzle 55 can be limited and installed. By setting the water outlet pipe 59, the water in the water tank 52 can be discharged as needed, so as to carry out maintenance operations such as cleaning and changing the water in the water tank 52, and ensure that the water cooling system can perform normally when the equipment is run again.

[0032] Working principle: When using this device, during the workpiece preparation stage, the clamping assembly 3 is used to securely clamp the workpiece. The workpiece is placed on the upper side of the support plate 2, and the position of the clamping plate 31 is adjusted to fit the workpiece size. The mounting bolts 33 on the connecting plate 32 on the outside of the clamping plate 31 pass through the limiting hole 34. Rotating the mounting bolts 33 tightens them into the threads of the limiting hole 34, firmly fixing the clamping plate 31 and firmly clamping the workpiece on the support plate 2. This prevents displacement during subsequent drilling and tapping, ensuring machining accuracy. When the water pump 53 is started, it draws water from the water tank 52. The water is transmitted to the nozzle 55 through the connecting hose 54 connected to the rear. The limiting block 56 on the outside of the nozzle 55 slides in the limiting groove 58 of the fixing plate 57, ensuring the stability of the nozzle 55 and ensuring that the coolant is accurately sprayed onto the drilling and tapping area. During machining, the coolant carries away the heat generated by the high-speed rotation of the drill bit, preventing the drill bit from overheating and the workpiece from being damaged due to thermal deformation, thus affecting accuracy. At the same time, it can also wash away the chips. With the help of several evenly distributed through holes 35 on the support plate 2, the chips and coolant fall together, keeping the machining area clean.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
