Description

Technical Field

[0001] The invention belongs to the technical field of CNC machine tool processing, and in particular relates to a spraying device for producing CNC machine tool parts. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process the parts according to the shape and size required by the drawing.

[0003] After the parts are processed in the CNC machine tool, they need to be painted, but the existing spraying device only has a single painting function. Generally, after the painting is completed, the product is taken out and placed in the drying room for drying. During this process, it is inconvenient for the staff to take the painted products, which is easy to damage the paint surface. It is also time-consuming and labor-intensive, and the work efficiency is relatively low.

[0004] Therefore, in order to solve this problem, it is necessary to develop and design a spraying device for producing CNC machine tool parts, which solves the problem of low working efficiency of the existing spraying device for producing CNC machine tool parts. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of an embodiment of the present invention is to provide a spraying device for producing CNC machine tool parts to solve the problems in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A spraying device for producing parts of numerically controlled machine tools comprises a machine platform, a paint spraying valve, a clamping block and a drying device, wherein the paint spraying valve is connected to a paint spraying pump through a telescopic hose, the paint spraying pump is connected to a paint box through a pipeline, the paint spraying pump is connected to the machine platform through a base, a driven shaft is fixedly connected in a bearing embedded in a side wall of the machine platform, a first gas strut is fixedly connected to the end of the driven shaft, a second motor fixedly connected to the side wall of the machine platform is connected to a second gas strut through a driving shaft, two clamping blocks are respectively fixedly connected to the ends of the first gas strut and the second gas strut, a laser sensor is embedded in the bottom of the clamping block, a laser emitter is embedded in the inner wall of the machine platform, and the positions of the laser sensor and the laser emitter correspond, the laser sensor is connected to an input end of a controller fixedly connected to the side wall of the machine platform through a wire, and an output end of the controller is connected to the drying device and the second motor through a wire.

[0008] As a further solution of the present invention, the driven shaft and the driving shaft are respectively connected to a second gear through a key, the second gear is connected to the first gear embedded in the bottom of the screw through gear teeth, the slider embedded in the side wall of the paint valve is slidably connected to the screw, the top of the screw is fixedly connected to the inner wall of the machine, the number of the screws is two, and they are symmetrically distributed on both sides of the paint valve.

[0009] As a further solution of the present invention, the drying device includes a shell, a fan and an electric heating wire. The fan is connected to the first motor through a motor shaft. The electric heating wire is fixedly connected to the inner wall of the shell and connected to an internal power supply through a wire. A plurality of through holes are opened on the surface of the shell, and the number of the fans is three.

[0010] As a further solution of the present invention, a temperature sensor is also embedded on the inner wall of the machine.

[0011] As a further solution of the present invention, a timer is also embedded on the outer wall of the machine.

[0012] As a further solution of the present invention, the temperature sensor and the timer are connected to the input end of the controller through wires, and the output end of the controller is connected to the electric heating wire and the second motor through wires.

[0013] As a further solution of the present invention, a plurality of suction nozzles are embedded on the surface of the clamping block, the suction nozzles are in contact with the side wall of the workpiece, and the suction nozzles are made of soft silicone.

[0014] In summary, compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0015] The two clamping blocks can clamp the side wall of the suction nozzle through the suction nozzle, which not only plays a fixing role but also does not damage the paint surface. At the same time, the second gas strut can drive the first gas strut to rotate together through the mutual clamping connection between the two clamping blocks and the workpiece. When the workpiece surface is painted, the second motor is started to drive the clamping block and the workpiece to rotate. When the workpiece rotates by degrees (that is, the painted surface is directly below), the laser sensor will reach the position of the laser transmitter and transmit the closing signal and the starting signal to the second motor and the drying device respectively through the controller. At this time, the workpiece is stationary and is dried by the drying device. The paint valve above can continue to paint the other side of the workpiece. When the baking time reaches a certain value, the timer will transmit the opening signal to the second motor through the controller, and the second motor will reverse to continue baking the other painted surface of the workpiece.

[0016] When the driven shaft and the driving shaft rotate, the screw is driven to rotate by the gear meshing transmission principle, so that the paint valve moves upward along the axis of the screw through the sliders on both sides, which can avoid the workpiece and prevent the workpiece from hitting the upper paint valve during rotation when the workpiece is large, which may cause damage. It has the characteristics of good humanization and strong flexibility.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments. Example

[0024] See also Figure 1 to Figure 2A spraying device for producing CNC machine tool parts includes a machine 1, a paint spray valve 6, a clamping block 15 and a drying device 17. The paint spray valve 6 is connected to a paint spray pump 4 through a telescopic hose 5. The paint spray pump 4 is connected to a paint box 2 through a pipeline. The paint spray pump 4 is connected to the machine 1 through a base 3. The paint spray valve 6 can spray paint on the surface of a workpiece 22 below. The telescopic hose 5 can change its own length as the height of the paint spray valve 6 changes, and has the characteristic of high flexibility.

[0025] A driven shaft 12 is fixedly connected in the bearing 11 embedded in the side wall of the machine 1, and a first gas strut 13 is fixedly connected to the end of the driven shaft 12. The first gas strut 13 can rotate in the bearing 11 through the driven shaft 12. The second motor 25 fixedly connected to the side wall of the machine 1 is connected to the second gas strut 24 through the drive shaft 26. The second motor 25 can drive the second gas strut 24 to rotate through the drive shaft 26. The number of the clamping blocks 15 is two, and they are fixedly connected to the ends of the first gas strut 13 and the second gas strut 24 respectively. The surface of the clamping block 15 is inlaid with a plurality of suction nozzles 151, and the suction nozzles 151 are in contact with the side wall of the workpiece 22. The first gas strut 13 and the second gas strut 24 can freely expand and contract according to the size of the workpiece 22, and have the characteristics of strong applicability. The two clamping blocks 15 can clamp the side wall of the suction nozzle 151 through the suction nozzle 151, which not only plays a fixing role, but also does not damage the paint surface. At the same time, the second gas strut 24 can drive the first gas strut 13 to rotate together through the mutual clamping connection between the two clamping blocks and the workpiece 22.

[0026] A laser sensor 16 is embedded in the bottom of the clamping block 15, and a laser emitter 14 is embedded in the inner wall of the machine 1. The laser sensor 16 corresponds to the position of the laser emitter 14. The laser sensor 16 can accurately capture the laser signal emitted by the laser emitter 14. The laser sensor 16 is connected to the input end of the controller 28 fixedly connected to the side wall of the machine 1 through a wire, and the output end of the controller 28 is connected to the drying device 17 through a wire.

[0027] When the surface of the workpiece 22 is painted, the second motor 25 is started to drive the clamping block 15 and the workpiece 22 to rotate. When the workpiece 22 rotates 180° (that is, the painted surface is directly below), the laser sensor 16 reaches the position of the laser emitter 14, and transmits the closing signal and the starting signal to the second motor 25 and the drying device 17 respectively through the controller 28. At this time, the workpiece 22 is stationary and is dried by the drying device 17. Then the paint valve 6 above can continue to paint the other side of the workpiece 22. Compared with the traditional paint spraying device, this device has the characteristics of high degree of automation and high working efficiency.

[0028] The drying device 17 includes a shell, a fan 18 and an electric heating wire 19. The electric heating wire 19 is used to heat and bake the workpiece 22. The fan 18 can speed up the air flow speed and improve the drying efficiency. The fan 18 is connected to the first motor 21 through the motor shaft. The electric heating wire 19 is fixedly connected to the inner wall of the shell and connected to the internal power supply through a wire. A plurality of through holes are opened on the surface of the shell to facilitate heat volatilization. The number of the fans 18 is three.

[0029] The inner wall of the machine 1 is also inlaid with a temperature sensor 23, which can monitor the internal temperature changes. When the temperature reaches a certain value, a shutdown signal will be sent to the controller 28 through the controller 28 to stop heating to prevent the workpiece 22 and the paint surface from being damaged by excessive temperature. The outer wall of the machine 1 is also inlaid with a timer 27, which can accurately record the baking time. When the time reaches a certain value, the controller 28 will transmit an opening signal to the second motor 25, and the second motor 25 will reverse to continue baking the other painted surface of the workpiece 22. The temperature sensor 23 and the timer 27 are connected to the input end of the controller 28 through a wire, and the output end of the controller 28 is connected to the electric heating wire 19 and the second motor 25 through a wire.

[0030] Preferably, the suction nozzle 151 is made of soft silicone, which has the characteristics of strong adsorption ability and soft texture, and will not cause damage to the workpiece 22. Example

[0031] See also Figure 1 and Figure 3 , a spraying device for producing CNC machine tool parts, also includes a driven shaft 12, the driven shaft 12 and the driving shaft 26 are respectively connected with a second gear 10 through a key, the second gear 10 is connected to the first gear 9 embedded in the bottom of the screw 8 through gear teeth, the slider 7 embedded in the side wall of the paint spray valve 6 is slidably connected to the screw 8, the top of the screw 8 is fixedly connected to the inner wall of the machine table 1, the number of the screw 8 is two, and they are symmetrically distributed on both sides of the paint spray valve 6, when the driven shaft 12 and the driving shaft 26 rotate, the screw 8 is driven to rotate by the gear meshing transmission principle, so that the paint spray valve 6 moves upward along the axis direction of the screw 8 through the sliders 7 on both sides, and can avoid the workpiece 22, to prevent the workpiece 22 from hitting the upper paint spray valve 6 when rotating when the workpiece 22 is large in size, which is easy to cause damage, and has the characteristics of good humanization and strong flexibility.

[0032] The rest of the structure of this embodiment is the same as that of Embodiment 1.

[0033] The working principle of the present invention is: first, fix the workpiece 22 between the two clamping blocks 15, then start the paint pump 4, and paint the surface of the workpiece 22 through the paint valve 6. When the paint on the surface of the workpiece 22 is completed, start the second motor 25 and drive the clamping block 15 and the workpiece 22 to rotate. When the workpiece 22 rotates 180° (that is, the painted surface is located directly below), the laser sensor 16 will reach the position of the laser emitter 14, and transmit the closing signal and the starting signal to the second motor 25 and the drying device 17 respectively through the controller 28. At this time, the workpiece 22 is in a stationary state and is dried by the drying device 17. Then the upper paint valve 6 can continue to paint the other side of the workpiece 22. When the baking time reaches a certain value, the timer 27 will transmit the opening signal to the second motor 25 through the controller 28, and the second motor 25 will reverse to continue baking the other painted surface of the workpiece 22.
