Description

Technical Field

[0001] This utility model relates to the field of horizontal machine tool technology, and in particular to a ventilation base for a horizontal machine tool. Background Technology

[0002] The machine tool base is the part of the machine tool that contacts the ground. During machine operation, components such as the motor and transmission system (e.g., gears, lead screws) generate a significant amount of heat due to friction and energy loss. This heat is conducted to the base, and if it cannot dissipate in time, the base temperature will rise. Metal materials (such as cast iron and steel) have thermal expansion and contraction characteristics; overheating of the base may cause slight deformation, affecting the straightness of the machine tool guideways and the positioning accuracy of each axis, leading to dimensional errors and excessive surface roughness in the machined parts. Furthermore, the motor is connected to the spindle and is exposed, resulting in excessive length and space occupation. This is especially problematic for some models that are difficult to fit into shipping containers, requiring off-site disassembly and reassembly, making transportation inconvenient. Therefore, a horizontal machine tool ventilated base is needed.

[0003] Chinese patent document CN222449224U discloses a CNC machine tool base, which has a water storage device fixedly connected to the side surface of the base side wall. The water storage device includes a trapezoidal water storage cavity, and a handle is fixedly connected to the side surface of the trapezoidal water storage cavity. The internal support is connected to reduce the weight of the entire base. An inclined groove is provided on the top plate, which makes it easier for liquid falling on the base to flow out of the machine tool base. The support includes an upright support and an inclined support, and has a cross-shaped cross section, which can reduce the weight without reducing the support strength.

[0004] The existing technology has the following problems:

[0005] 1. The heat dissipation of the base mainly relies on the natural flow of air, and the heat dissipation effect is generally average.

[0006] Second, the motor is located on the left side of the base and is exposed, which will occupy a certain amount of space and easily cause inconvenience in transportation. Utility Model Content

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] like Figures 1-6 As shown, a horizontal machine tool ventilation base includes a base 1. A headstock 4 is fixedly installed on the upper left side of the base 1. A spindle 5 is rotatably connected through the middle left side of the headstock 4. A three-jaw chuck is fixedly connected to the right end of the spindle 5. Sliding rails 6 are fixedly installed at the front and rear positions of the upper right side of the base 1. A motor quick-connect assembly 2 is movably connected to the left side of the inner cavity of the base 1. A heat dissipation and cooling assembly 3 is fixedly installed in the inner cavity of the base 1.

[0032] The motor quick-mount assembly 2 includes a mounting frame 21, a receiving cavity 22 is provided on the top left side of the base 1, the outer side of the mounting frame 21 is fixedly installed with the inner wall of the receiving cavity 22, a fixing seat 23 is snapped into the bottom of the inner wall of the mounting frame 21, a motor 24 is fixedly installed on the top of the fixing seat 23, and a transmission structure 25 is movably connected to the output end of the motor 24 and the left side of the outer wall of the main shaft 5.

[0033] The heat dissipation assembly 3 includes two support bases 31. The lower ends of the two support bases 31 are fixedly connected to the left and right sides of the inner cavity of the base 1. Both support bases 31 are I-shaped structures. Cooling fans 32 are fixedly installed on the right side of the front and rear sides of the base 1.

[0034] The quick-release motor assembly 2 uses two relatively movable L-shaped fixing rods 214 to fix the fixing base 23, thereby fixing the motor 24 and simplifying the installation and removal of the motor 24, reducing the time and complexity of motor assembly and disassembly. The airflow cooling assembly 3 uses an I-shaped support base 31 to separate the cavity. When the cooling fan 32 is working, air is drawn in from the left ventilation slot 35, flows through the motor 24 and transmission components, and is then discharged from the fan, forming a cooling cycle and reducing the risk of heat-induced deformation of the base 1. Furthermore, the connecting base 34 and the two support bases 31 provide support for the internal structure of the base 1, enhancing overall rigidity.

[0035] like Figure 6 As shown, a slot is provided at the middle of the bottom of the inner wall of the mounting frame 21, and a matching slot plate 26 is fixedly installed at the middle of the lower end of the fixing seat 23.

[0036] The mounting base 23 inserts its bottom plate 26 into the slot, and the locking connection between the two facilitates the positioning of the motor 24.

[0037] like Figure 5 and Figure 6 As shown, mounting plates 27 are fixedly installed at the front and rear positions of the left side of the inner wall of the receiving cavity 22. The inner walls of the two mounting plates 27 are rotatably connected to a two-way lead screw 28. The front end of the two-way lead screw 28 is fixedly connected to a drive shaft 29 that passes through the front of the base 1. The front and rear parts of the outer wall of the two-way lead screw 28 are threaded with threaded sleeves 210. The outer side of the two-way lead screw 28 is fitted with a telescopic protective sleeve 211, which is divided into three parts.

[0038] The telescopic protective sleeve 211 is connected to the mounting plate 27 and the threaded sleeve 210 respectively. It extends and retracts as the threaded sleeve 210 moves, thus protecting the bidirectional lead screw 28.

[0039] like Figure 5 As shown, a guide frame 212 is fixedly installed at the bottom of the inner wall of the receiving cavity 22, and a slider 213 is fixedly installed at the lower end of each of the two threaded sleeves 210. The inner walls of the two sliders 213 are slidably connected to the front and rear parts of the inner wall of the guide frame 212.

[0040] The guide frame 212 guides the movement of the threaded sleeve 210.

[0041] like Figure 6 As shown, the upper ends of the two threaded sleeves 210 are fixedly installed with L-shaped fixing rods 214 that penetrate the front and rear parts of the mounting frame 21, and the front and rear sides of the fixing seat 23 are provided with fixing grooves 215 for matching L-shaped fixing rods 214.

[0042] Rotating drive shaft 29, bidirectional lead screw 28 rotates, two lead sleeves 210 move relative to each other through their threaded connection, thereby allowing two relatively moving L-shaped fixing rods 214 to be inserted into the fixing grooves 215 at the front and rear of the fixing seat 23, thus realizing the quick installation of motor 24.

[0043] like Figure 7 As shown, a turntable 216 is fixedly installed at the front end of the drive shaft 29. A groove 217 is provided at the rear edge of the turntable 216. A sliding column 218 is slidably connected to the inner wall of the groove 217. A plug rod 219 is fixedly installed at the rear end of the sliding column 218. Two positioning holes 220 for the plug rod 219 are provided on the front left side of the base 1. An adjusting rod 221 that passes through the front of the turntable 216 is fixedly installed at the front end of the sliding column 218. A spring 222 is movably sleeved on the rear part of the outer wall of the adjusting rod 221. The front end of the spring 222 is fixedly connected to the front part of the inner wall of the groove 217, and the rear end of the spring 222 is fixedly connected to the front end of the sliding column 218.

[0044] Before use, the drive shaft 29 is fixed by the insertion rod 219 to prevent vibration. A rotation indicator is provided on the front side of the turntable 216. First, the user pulls the adjusting rod 221, which overcomes the spring force of the spring 222 to move the sliding column 218 and the insertion rod 219 forward. The insertion rod 219 moves away from the positioning hole 220, at which point the turntable 216 is in a fixed position. Then, the user rotates the turntable 216 according to the rotation indicator. After the turntable 216 rotates 180°, the two L-shaped fixing rods 214 move away from each other, allowing the motor 24 to be disassembled. Finally, the adjusting rod 221 is released, and the spring 222 causes it to return to its original position, allowing the insertion rod 219 to insert into the positioning hole 220 at the bottom. This improves the stability of motor assembly and disassembly.

[0045] like Figure 3 and Figure 4 As shown, an inclined chip removal cavity 33 is provided in the middle of the upper end of the base 1. A connecting seat 34 is fixedly installed in the middle of the inner cavity of the base 1 relative to the chip removal cavity 33. The opposite sides of the two support seats 31 are fixedly connected to the left and right sides of the connecting seat 34. The connecting seat 34 and the two support seats 31 separate the front and rear parts of the base 1 into an air circulation cavity, which is connected to the receiving cavity 22.

[0046] like Figure 3 As shown, a number of ventilation slots 35 arranged in a linear pattern are provided through the bottom left side of the base 1, and the ventilation slots 35 are connected to the air circulation cavity.

[0047] The left ventilation slot 35 is connected to the air circulation cavity, forming a forced convection path of "left in and right out".

[0048] The working principle of this utility model is as follows: In use, the motor 24 is installed first, followed by the connection of the transmission structure 25. The mounting base 23 at the bottom of the motor 24 is placed into the mounting frame 21, allowing the retaining plate 26 at the bottom of the mounting base 23 to engage with the retaining groove. This locking connection facilitates the positioning of the motor 24. The drive shaft 29 is fixed by the insertion rod 219 before use to prevent vibration. A rotation indicator is provided on the front side of the turntable 216. The user first pulls the adjusting rod 221, which overcomes the spring force of the spring 222 to move the sliding column 218 and the insertion rod 219 forward. The insertion rod 219 moves away from the positioning hole 220, at which point the turntable 216 is in a fixed state. The user then rotates the turntable 216 according to the rotation indicator. After the turntable 216 rotates 180° counterclockwise, the two L-shaped fixing rods 214 move closer together, achieving the installation of the motor 24. Finally, the adjusting rod 221 is released, the spring 222 causes it to return to its original position, and the insertion rod 219 is inserted into the positioning hole 220 at the top. This improves the stability of the entire mounting structure. The installation of the belt in the transmission structure 25 is existing technology. Furthermore, existing technologies also include an adjustable tensioning structure within the inner cavity of the base 1 to ensure the stability of the belt drive. These are all feasible in existing technologies and will not be elaborated upon further. During machining, the transmission system of a horizontal machine tool generates a large amount of heat due to friction and energy loss. If this heat is not dissipated in time after being conducted to the base, it will cause the temperature of the base 1 to rise. The heat dissipation assembly 3 utilizes the I-shaped support 31 to separate the cavity. When the cooling fan 32 is working, air is drawn in from the left ventilation slot 35, flows through the motor 24 and transmission components, and is then discharged from the fan, forming a heat dissipation cycle and reducing the risk of deformation of the base 1 due to heat.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
