Description

Technical Field

[0001] This utility model relates to the technical field of lead screw processing equipment, specifically a lead screw processing equipment with a cooling mechanism. Background Technology

[0002] Lead screws play a vital role in the mechanical field, primarily functioning to transmit power, position, and support. In machine tools, construction machinery, and other equipment, lead screws, through their interaction with other components such as nuts and guide rails, convert rotary motion into linear motion, thereby completing the power transmission between devices. When used in conjunction with a worktable, lead screws enable high-precision workpiece positioning, ensuring the stability of the machining process. Their excellent load-bearing capacity and stability guarantee the normal operation and long service life of the equipment.

[0003] The main structure of a lead screw is relatively simple, consisting of a metal rod with one or two sets of threads machined on the outside. When machining a lead screw, especially one with two sets of threads, it is usually necessary to switch between two sets of equipment for machining, or to change the cutting head on one set of equipment. This is quite troublesome. When machining on the same set of equipment, the cooling mechanism also needs to be adjusted synchronously when switching the cutting head. This requires repeated debugging and does not have the function of cooling the cutting tool during the machining process.

The left and right movement of the lead screw can switch the processing position. Two different threads can be processed on the same machine without changing the tool, realizing the function of processing two threads at the same time on a single machine.

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.

[0025] Example: Please refer to Figure 1-4 A lead screw machining equipment with a cooling mechanism includes a housing 1.

Cooling components for facilitating the cooling of cutting tools are respectively provided at the top of the first sliding seat 13 and the second sliding seat 17.

[0026] Please see Figure 1-4A lead screw processing device with a cooling mechanism also includes a cooling assembly, which includes two sets of rigid fixed tubes 5. The two sets of rigid fixed tubes 5 are respectively fixedly connected to the top ends of the first sliding seat 13 and the second sliding seat 17. A nozzle 7 is fixedly connected to the bottom end of the rigid fixed tube 5. A coolant inlet pipe 2 is horizontally fixedly connected between the two sides inside the housing 1. A coolant pump inlet 3 is fixedly connected to the left side of the coolant inlet pipe 2. Two diversion hoses 4 are movably connected to the top end of the coolant inlet pipe 2. A solenoid valve 6 is installed between the diversion hoses 4 and the rigid fixed tubes 5.

[0027] The internal connections of the coolant inlet pipe 2, coolant pump inlet 3, and diversion hose 4 are interconnected. The diversion hose 4 is flexible. The solenoid valve 6 and the first electric cylinder 8 are electrically connected. The solenoid valve 6 is symmetrically distributed about the vertical center line of the housing 1. The first cutter head 15 and the second cutter head 16 are of different sizes. The vertical center line of the nozzle 7 is tangent to the front end of the first cutter head 15 and the second cutter head 16, which facilitates rapid cooling of the cutter.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, as the first electric cylinder 8 retracts, the solenoid valve 6 on the corresponding side opens simultaneously, and the external pump pumps the coolant into the machine through the coolant pump inlet 3. The coolant then enters the nozzle 7 through the coolant inlet pipe 2, the diversion hose 4, and the rigid fixed pipe 5. The nozzle 7 sprays the coolant downwards to quickly cool the machining position.

[0029] The shape and size of the bottom of the slide table 10 are adapted to the shape and size of the top of the first slide rail 9. The slide table 10 can slide left and right along the outside of the first slide rail 9. The output end of the first electric cylinder 8 is connected to one side of the slide table 10. The shape and size of the bottom of the first sliding seat 13 and the second sliding seat 17 are adapted to the shape and size of the top of the second slide rail 11. The first sliding seat 13 and the second sliding seat 17 can slide back and forth along the outside of the second slide rail 11. The output ends of the two sets of second electric cylinders 12 are respectively connected to the rear ends of the first sliding seat 13 and the second sliding seat 17. Two different threads can be processed simultaneously on the same machine.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, the first electric cylinder 8 pulls the slide table 10 to slide left and right, so that the lead screw reaches the corresponding processing position. The second electric cylinder 12 extends and retracts, which can push the corresponding first sliding seat 13 and second sliding seat 17 to move back and forth. The left and right movement of the lead screw can switch the processing position, and two different threads can be processed on the same machine without changing the tool.

[0031] The fixture mounting plate 19 has four sets of fixture mounting screw holes 20 inside. The four corners at the top of the fixture mounting plate 19 are respectively provided with upper circular grooves 21, and the four corners at the bottom of the fixture mounting plate 19 are respectively provided with lower screw holes 22. The lower screw holes 22 are vertically inserted with fixing bolts 23. The front and rear ends of the top of the slide table 10 are respectively provided with multiple sets of positioning screw holes 24. The top of the fixing bolts 23 is flush with the top of the fixture mounting plate 19. The external threads of the fixing bolts 23 match the internal threads of the lower screw holes 22 and positioning screw holes 24. The positioning screw holes 24 are arranged at equal intervals to facilitate the adjustment of the fixture installation position.

[0032] Specifically, such as Figure 2 and Figure 4 As shown, loosen the fixing bolt 23 to disengage it from the positioning screw hole 24, and the entire clamp mounting plate 19 can be removed. The upper circular groove 21 provides space for the hexagonal head at the top of the fixing bolt 23 to sink, thus avoiding affecting the installation of the clamp.

[0033] Working Principle: In use, the fixture is first fixed on the fixture mounting plate 19. Two sets of fixtures clamp the lead screw blank. The first electric cylinder 8 pulls the slide table 10 to slide left and right, so that the lead screw reaches the corresponding processing position. As the lead screw blank reaches the corresponding processing position, the first drive motor 14 drives the first cutter head 15 to rotate at high speed, and the second drive motor 18 drives the second cutter head 16 to rotate at high speed. As the first electric cylinder 8 retracts, the solenoid valve 6 on the corresponding side opens synchronously. The external pump pumps coolant into the machine through the coolant pump inlet 3. The coolant enters the nozzle 7 through the coolant inlet pipe 2, the diversion hose 4, and the rigid fixing pipe 5. The nozzle 7 sprays coolant downwards to quickly cool the processing position. The first electric cylinder 8 pulls the slide table 10 to slide left and right, so that the lead screw reaches the corresponding processing position. The second electric cylinder 12 extends and retracts, which can push the corresponding first sliding seat 13 and second sliding seat 17 to move back and forth. The left and right movement of the lead screw can switch the processing position, and two different threads can be processed on the same machine without changing the cutting tools. The fixture is fixed on the fixture mounting plate 19. The position of the fixture mounting plate 19 can be adjusted according to the size of the lead screw blank and the specifications of the fixture to achieve the most suitable clamping effect. Loosen the fixing bolt 23 to disengage it from the positioning screw hole 24, and the fixture mounting plate 19 can be removed as a whole. The upper circular groove 21 provides space for the hexagonal head at the top of the fixing bolt 23 to sink, so as to avoid affecting the installation of the fixture.
