Description

Technical Field

[0002] Existing gantry-type machine tools, especially surface grinders, need to be installed in a constant temperature workshop to achieve greater precision. The higher the required precision, the higher the construction cost of the constant temperature workshop. At the same time, as the size of the workpieces increases, the equipment travel also increases, which in turn increases the volume occupied by the machine tools and the floor space of the constant temperature workshop. As the area of ​​the constant temperature workshop increases, the energy cost required to maintain constant temperature and humidity conditions within the constant temperature workshop increases. Moreover, in a large space, it is difficult to quickly and directly transfer temperature to the machine tools. The constant temperature workshop must operate for a long time to ensure a constant temperature for the machine tools inside. The larger the area of ​​the constant temperature workshop, the more difficult it is to stabilize the temperature. In addition, the constant temperature workshop must add one or more cranes to facilitate the loading and unloading of the machine tools, which increases the crane costs.

The temperature adjustment does not form a true closed-loop control, the temperature feedback is not timely, and the temperature adjustment is not sensitive.

[0047] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0048] It should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0049] Gantry-type surface grinders require a machining accuracy of less than 1 thread per square meter. This accuracy places extremely high demands on temperature. A 10°C rise in the workpiece temperature can cause the flatness to decrease by 5 threads per square meter. Temperature significantly impacts machining accuracy. Therefore, existing surface grinders must be placed in a constant temperature room to ensure high precision. The more stable the temperature in the constant temperature room, the higher the machining accuracy of the surface grinder.

[0050] As workpieces grow in size, surface grinder strokes are also increasing. A 6-meter-stroke machine now occupies nearly 100 square meters, measuring 12 meters by 8 meters. This increasing floor space also increases the size of the constant-temperature workshop. The larger the constant-temperature workshop, the more difficult it is to maintain a stable temperature. As the area increases, the difficulty of maintaining temperature increases exponentially, as does the construction cost and energy consumption. Therefore, for gantry-type surface grinders with large footprints, achieving stable constant temperature control while reducing construction costs and energy consumption has become a pressing challenge.

[0051] Since the processing accuracy of the gantry-type surface grinder is determined by the three main beams, this application proposes a new idea, which is to cover the three main beams in the constant temperature workshop only to ensure the temperature stability of the three main beams. There is no need to build a large constant temperature room. The larger the stroke, the lower the cost. There is no need to reinstall the crane, and the constant temperature area is greatly reduced, and the constant temperature effect is significantly improved. The machine tool accuracy far exceeds the processing accuracy of the constant temperature workshop, and can reach a flatness of 0.5 inches per square meter, and the accuracy can be improved by 1 major level.

[0052] Example 1

[0053] In a typical embodiment of the present application, a constant temperature device for a marble gantry surface grinder is provided, such as Figure 1-9 As shown, the constant temperature device of this embodiment is applied to a surface grinder, which includes three main beams, namely side beam 1 and cross beam 2. The side beam 1 includes a left beam and a right beam. The tops of the left beam and the right beam are equipped with guide rails for horizontal movement of the cross beam. The cross beam 2 is slidably connected to the left and right beams respectively through guide rails and screw structures, and can move linearly along the guide rails under power drive.

[0054] The constant temperature device of this embodiment includes an industrial constant temperature machine 3 and a multi-channel constant temperature pipe 4, wherein the constant temperature pipe 4 includes a side beam constant temperature pipe 41 installed on the left beam and the right beam respectively, and a cross beam constant temperature pipe 42 installed on the cross beam;

[0055] The industrial thermostat 3 includes an industrial thermostat liquid outlet 31 and an industrial thermostat liquid return port 32. The industrial thermostat liquid outlet 32 ​​is fixedly connected to a liquid inlet pipe diverter 5. The liquid inlet pipe diverter 5 connects the parallel side beam thermostat pipes 41 and the cross beam thermostat pipe 42. The side beam thermostat pipes 41 are arranged on the side of the side beam 1, and the cross beam thermostat pipe 42 is arranged on the back and bottom of the cross beam 2. Guide rails and screws are installed on the front and top of the cross beam, making it impossible to spray insulation material, so the thermostat pipes cannot be installed.

[0056] Specifically, in order to save costs, this embodiment uses an industrial constant temperature machine 3, such as Figure 1 As shown, the industrial thermostat 3 has an industrial thermostat liquid outlet 31 and an industrial thermostat liquid return port 32. The industrial thermostat liquid outlet 31 is fixedly connected to the liquid inlet pipe diverter 5. The liquid inlet pipe diverter 5 is connected to multiple thermostat pipes, which include the side beam thermostat pipe 41 and the cross beam thermostat pipe 42. Among them, the side beam thermostat pipe 41 is arranged on the left and right sides of the side beam track mounting surface, including the left side of the left beam, the right side of the left beam, the left side of the right beam, and the right side of the right beam. The cross beam thermostat pipe 42 is arranged below and behind the cross beam. The industrial thermostat liquid return port 32 is fixedly connected to the return liquid pipe diverter 6, and the return liquid pipe diverter 6 is connected to the return liquid ports of each thermostat pipe.

[0057] Specifically, the side beam constant temperature pipes 41 are arranged on the left and right sides of the guide rail mounting surface of the side beam 1. In order to achieve rapid and uniform cooling, in this embodiment, Figure 2-4 As shown, the side beam constant temperature pipe 41 is divided into two constant temperature pipe loops, one on the left and one on the right. The two constant temperature pipe loops are arranged parallel to the guide rail. Each loop is arranged with several rows of parallel pipes. One end of each adjacent two parallel pipes is connected in an arc shape and staggered to form an overall serpentine distribution. The side beam can be grooved along the length of the side beam to install the side beam constant temperature pipe, or it can be not grooved and the constant temperature pipe can be directly fixed on the side beam parallel to the guide rail. The side beam constant temperature pipe 41 includes a side beam liquid inlet 411 and a side beam liquid return port 412. The left and right side beam liquid inlets 411 are both set above the side beam 1 and are fixedly connected to the liquid inlet pipe diverter 5 respectively. The two side beam liquid return ports 412 are respectively connected to the liquid return pipe diverter 6. The refrigerant can use its own weight to quickly and evenly reach the liquid return port, reduce the liquid supply pressure of the industrial thermostat, and achieve the effect of rapid and uniform cooling of an industrial thermostat.

[0058] Of course, in other embodiments, the constant temperature pipe of the side beam can also be wrapped around the side of the side beam several times to form a constant temperature pipe loop, and the overall distribution is spiral. At this time, the liquid inlet of the side beam is located above the side beam, and the liquid return port of the side beam is located below the side of the side beam.

[0059] Specifically, a beam thermostatic pipe 42 is arranged on the rear and bottom surface of the beam 2. To achieve the rapid and uniform cooling effect of an industrial thermostat, the beam thermostatic pipe arranged at the rear is fixedly connected to the beam thermostatic pipe below to form a thermostatic pipe loop. The beam 2 can be grooved parallel to the length of the beam, and the beam thermostatic pipe placed in the groove, or it can be ungrooved and the thermostatic pipe directly fixed to the beam parallel to the length of the beam. The beam thermostatic pipe 42 includes a beam liquid inlet 421 and a beam liquid return port 422. The beam liquid inlet 421 is connected to the liquid inlet pipe diverter 5, and the beam liquid return port 422 is connected to the liquid return pipe diverter 6.

[0060] like Figure 5-8 As shown, the beam liquid inlet 421 is located above the rear of the beam 2, and the beam liquid return port 422 is located on the bottom surface of the beam 2. The beam liquid inlet 421 and the beam liquid return port 422 pass through the drag chain 10 and are fixedly connected to the liquid inlet pipe diverter 12 and the liquid return pipe diverter 13 respectively. The constant temperature pipe in the drag chain 10 is wrapped with a hose and insulation material. The refrigerant can use its own weight to quickly and evenly reach the liquid return port, reducing the liquid supply pressure of the industrial constant temperature machine, thereby further achieving the effect of rapid and uniform cooling of an industrial constant temperature machine, reducing costs while improving the efficiency of temperature regulation.

[0061] In other embodiments, the installation method of the beam constant temperature pipe can also be set to be installed perpendicular to the guide rail direction. Figure 9 As shown, the beam constant temperature pipe 42 is arranged in parallel rows on the back and bottom of the beam perpendicular to the guide rail, and the direction is also serpentine, forming a constant temperature pipe loop. At this time, the beam liquid inlet 421 and the beam liquid outlet 422 are distributed on two planes. Of course, it is also possible to choose to divide it into two loops, arranging multiple parallel rows of pipes on the left and right sides respectively, and connecting them to the industrial constant temperature machine respectively.

[0062] In this embodiment, the constant temperature pipe loops on the left and right side surfaces of the side beam 1 and the back and bottom of the cross beam 2 are covered or sprayed with insulation materials. The specific method is determined according to the structural characteristics, so that the constant temperature pipes, the surroundings of the side beams, and the back and bottom of the cross beams are completely isolated from the external environment. The temperature of the constant temperature pipes can be guaranteed by ensuring the temperature of the side beams and the cross beams. The insulation material is waterproof, and the water vapor generated by the constant temperature pipes will not affect the core components such as the guide rails and the screws.

[0063] However, the guide rail mounting surfaces of the side beams and cross beams are in indirect contact with the external environment and cannot be sprayed. Even if covered with insulation materials, they cannot be completely isolated from the external environment. Therefore, the large temperature difference between the guide rail mounting surface and the external environment will generate water vapor. Since the entire bed of the gantry machine tool is made of natural marble, water vapor will not have any effect on the three main beams, but will corrode core transmission components such as guide rails and lead screws. Therefore, in this embodiment, if Figure 2 、 5As shown, an oil pool baffle 9 is installed on the guide rail mounting surface of the side beam and the cross beam. The oil pool is composed of the oil pool baffle. The oil pool completely immerses the guide rail and the screw, which can prevent the influence of water vapor on the core transmission components such as the guide rail and the screw; and the oil pool also has a certain heat preservation effect. The side beam and the cross beam are equipped with oil drain ports to discharge water vapor regularly; the guide rail and the screw in front of the cross beam will not accumulate water vapor to corrode the guide rail and the screw due to the installation method.

[0064] In this embodiment, several temperature sensors 8 are fixedly installed on the layout surfaces of the side beam constant temperature pipe 41 and the cross beam constant temperature pipe 42. The temperature sensors 8 are connected to the industrial constant temperature machine 3 for detecting the temperature of each point and feeding back the temperature to the industrial constant temperature machine through the controller. The industrial constant temperature machine can control the proportional valve of each circuit according to the temperature of each point, thereby quickly adjusting the temperature of the constant temperature pipe.

[0065] Specifically, if Figure 1 、 2 As shown in Figures 5 and 5, the left and right sides of the side beam 1 and the back and bottom of the cross beam 2 are fixedly connected with temperature sensors 8, forming a temperature sensor array. The temperature trend of the entire beam can be sensed and visualized through software. In order to achieve the effect of rapid cooling, the weight of the temperature of each temperature sensor gradually increases with the flow direction of the refrigerant in the constant temperature pipe. For example, there are a total of ten temperature sensors with an average weight of 0.1. The weight of the first sensor of each beam is much lower than 0.1, and the weight of the last sensor is much higher than 0.1. The sum of the weights of all sensors is still 1. The average temperature of the entire beam is calculated as the end temperature of the beam through the different weights of each temperature sensor. The temperature of each sensor multiplied by the weight is the end temperature of the beam. The end temperature is used as the adjustment temperature of the industrial thermostat, which can truly realize closed-loop control, and it is fast, efficient and stable.

[0066] In addition, since the beam constant temperature pipe needs to pass through the drag chain 10, the beam constant temperature pipe is a bit long, and the liquid inlet pipe diverter can only evenly distribute the flow rate, resulting in a relatively slow cooling effect of the beam, the temperature cannot be quickly fed back, and the accuracy will deteriorate. Therefore, in this embodiment, a proportional valve 7 is added in front of the liquid inlet pipe diverter 5, such as Figure 1 As shown, proportional valve 7 is installed at the outlet of the inlet pipe diverter 5. It can proportionally distribute the coolant flow rate according to the terminal temperature of the temperature sensor in each thermostatic pipe loop. For example, after the side beam temperature stabilizes, if the cross beam temperature difference is large, the proportional valve of the side beam thermostatic pipe can be adjusted downward through software, while the proportional valve of the cross beam thermostatic pipe can be adjusted upward through software, thereby achieving rapid cross beam cooling.

[0067] Example 2

[0068] In another typical implementation of this embodiment, considering that the beam constant temperature pipe needs to pass through the drag chain, the beam constant temperature pipe is long, resulting in a poor constant temperature effect. In order to further improve the temperature adjustment accuracy and constant temperature control effect, in this embodiment, Figure 10 As shown, a beam thermostat 11 is separately configured for the beam. The beam thermostat 11 is fixedly installed behind the beam 2. The beam thermostat 11 includes a beam thermostat liquid outlet 111 and a beam thermostat liquid return port 112. The beam thermostat liquid outlet 111 is connected to the liquid inlet of the beam thermostat pipe, and the beam thermostat liquid return port 112 is connected to the liquid return port of the beam thermostat pipe, forming a dual industrial thermostat structure.

[0069] In order to further enhance the effect of rapid cooling of the beam, in a preferred embodiment, the beam constant temperature pipe 42 can be divided into two constant temperature pipe loops, one behind the beam and one on the bottom of the beam. Figure 11 The two loops can be arranged in the same manner as in the first embodiment, in a serpentine arrangement, and can be installed parallel to the length of the beam or perpendicular to the length of the beam.

[0070] At the same time, a beam liquid inlet pipe diverter 12 is provided at the liquid outlet 111 of the beam constant temperature machine and is fixedly connected, a beam return liquid pipe diverter 13 is provided at the liquid return port 112 of the beam constant temperature machine and is fixedly connected, the beam liquid inlet pipe diverter 12 is respectively connected to the beam liquid inlet 421 located on the bottom surface of the beam and behind the beam, and the beam return liquid pipe diverter 13 is respectively connected to the beam return liquid port 422 located on the bottom surface of the beam and behind the beam, forming a dual industrial constant temperature machine beam diversion structure.

[0071] Due to the use of dual industrial thermostats, the industrial thermostat near the surface grinder only needs to supply refrigerant to the thermostat pipes of the four circuits of the side beam, which reduces the liquid supply pressure and further improves the cooling or heating efficiency.

[0072] In order to achieve more uniform cooling and thus improve the uniformity of the side beam temperature, in a preferred embodiment, the side beam constant temperature pipe can be set as a loop, and the constant temperature pipe installation method can be divided into two types: parallel to the guide rail direction and perpendicular to the guide rail direction.

[0073] like Figure 12-15 As shown, the side beam constant temperature pipe 41 is arranged parallel to the guide rail direction, and the side beam constant temperature pipe 41 is wrapped around the side of the side beam 1 for several turns to form a constant temperature pipe loop, and the overall distribution is spiral. At this time, the side beam liquid inlet 411 and the side beam liquid return port 412 are distributed on two planes, and the side beam liquid inlet 411 is located above the side beam, and the side beam liquid return port 412 is located below the side of the side beam.

[0074] like Figure 16-18As shown, the installation method of the side beam constant temperature pipe can also be set to be installed perpendicular to the guide rail. The side beam constant temperature pipes 41 are arranged in several parallel rows on both sides of the side beam along the direction perpendicular to the guide rail, with a serpentine distribution, forming a constant temperature pipe loop. In this case, the side beam liquid inlet 411 and the side beam liquid return port 412 are distributed on two planes, and the side beam liquid inlet 411 and the side beam liquid return port 412 are both located on the upper side of the side beam.

[0075] It should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Those skilled in the art will appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
