Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical parts processing, and more specifically, it relates to a spraying device for mechanical parts processing. Background Art
[0002] Under the existing technical background, spraying equipment in the field of mechanical parts processing faces many challenges and limitations. One of the most significant problems is the placement and adjustment method of traditional spraying equipment. Traditionally, spraying equipment relies on machine tools to achieve stable placement on the ground. However, since most machine tools adopt a fixed structure, this means that when faced with uneven ground, operators often need to use cutting pads to adjust the balance of the machine tools. This method not only increases the complexity of installation, but may also affect the overall stability of the machine tools and the spraying effect, thereby adversely affecting production efficiency and product quality.
[0003] Further considering the problem of paint delivery, in the prior art, the spraying device usually requires an external delivery device to deliver the paint to the inside of the device for spraying. However, a key problem is that the existing input pipeline design lacks an effective flow rate adjustment mechanism. This defect makes it impossible for operators to accurately control the flow rate of the paint in the pipe and the input speed inside the equipment, which in turn affects the uniformity and accuracy of the spraying process. In the face of high-precision processing requirements, this unadjustable flow rate may lead to inconsistent coating thickness, affecting the quality and appearance of the final product.
[0004] In addition, the process of connecting the conveying equipment with the spraying equipment also faces many challenges in the existing technology. The existing connection methods are often complicated and cumbersome, which not only consumes a lot of time and labor, but may also affect the stability of the equipment and the spraying efficiency due to improper operation. Under the tight production scheduling and high quality requirements, this overly complicated connection operation is obviously not conducive, and when the conveying equipment and the spraying equipment need to be disconnected for maintenance, the maintenance time is long, which disrupts the production continuity.

[0032] Protection curtains 18 are symmetrically arranged on both sides of the protection chamber 6 , and the protection curtains 18 can be detachably installed on both sides of the protection chamber 6 .
[0033] An anti-skid pad 19 is provided at the bottom end of the support block 4 , and the anti-skid pad 19 is fixedly installed at the bottom end of the support block 4 .
[0034] Sliding blocks 20 are provided on both sides of the adjusting sleeve 14 , and sliding grooves 21 are correspondingly opened on one side of the delivery pipe 7 and the one-way pipe 12 , and the sliding blocks 20 are slidably installed in the sliding grooves 21 .
[0035] In this embodiment, the machine tool 1 is first placed on the ground. When the ground is uneven, the adjusting screw 2 is rotated in the corresponding direction. Since the adjusting screw 2 and the fixing nut 3 are movably connected by threads, and the fixing nut 3 is fixedly installed on the machine tool 1, the adjusting screw 2 will move up and down accordingly when it is rotated. When the anti-skid pad 19 set at the bottom end of the support block 4 is flush with the ground, the adjusting screw 2 is stopped, and then the machine tool 1 is leveled according to this operation, so as to ensure the stability of the machine tool 1 when in use. The anti-skid pad 19 can increase the friction between the equipment and the ground, further enhancing the stability of the machine tool 1 when in use. Then, the parts to be processed are placed on the conveying assembly 5, and the parts to be sprayed are driven by the power element in the conveying assembly 5 to convey the parts to be sprayed into the protective bin 6. Then, the power element is temporarily turned off, and then the paint is conveyed to the spraying assembly set in the protective bin 6 through the conveying pipe 7 by the external conveying equipment, and then the paint is sprayed onto the surface of the parts. During this process, the protective curtains 18 arranged on both sides of the protective bin 6 can prevent the paint from being sprayed onto the outside of the equipment. When the input flow rate of the delivery pipe 7 needs to be adjusted, the adjusting sleeve 14 is rotated in the corresponding direction. At the same time, the sliding blocks 20 arranged on both sides of the adjusting sleeve 14 will slide in the corresponding sliding grooves 21 respectively. Then, the unlocking sleeve will drive the corresponding limiting rod 9 to rotate through the limiting frame 8 with a special structural design. Due to the special structural design of the spiral groove 13 and the existence of the guide ball 16, when the limiting rod 9 drives the blocking frame 10 to rotate, the blocking frame 10 will move upward at the same time, and then the exposed area of the water trough 11 will become larger and larger, thereby achieving the purpose of adjusting the input flow rate of the delivery pipe 7. When it is adjusted to the appropriate position, stop rotating the unlocking sleeve. During this process, the second spring 15 can ensure the stability of the movement of the blocking frame 10, and the third spring 17 can ensure the fit between the guide ball 16 and the spiral groove 13, and can also apply pressure when it is not rotating to prevent it from rotating easily.
[0036] See also Figure 1-4 , as an implementation method of a spraying equipment for mechanical parts processing of a clamping mechanism: the clamping mechanism includes a connecting tube 22, a limiting sleeve 23, a clamping groove 24, a limiting ball 25, a through groove 26 and a receiving groove 27, one end of the connecting tube 22 extends into the limiting sleeve 23, the limiting sleeve 23 is detachably installed in the one-way tube 12, the clamping groove 24 is provided on the inner wall of the one-way tube 12, the through groove 26 runs through the side wall of the limiting sleeve 23, the limiting ball 25 is movably installed in the through groove 26, and the receiving groove 27 is provided on the outside of the connecting tube 22.
[0037] A first spring 28 is disposed in the limiting sleeve 23 , and the first spring 28 is movably mounted on the outside of the connecting pipe 22 .
[0038] A slider 29 is disposed on the outer side of the limiting sleeve 23 , a slide groove 30 is correspondingly provided on the inner side of the one-way tube 12 , and the slider 29 is slidably installed in the slide groove 30 .
[0039] A control sleeve 31 is provided at one end of the connecting pipe 22 , and the control sleeve 31 is fixedly installed on the outside of the connecting pipe 22 .
[0040] More specifically, when the spraying equipment needs to be disconnected from the external conveying equipment for replacement and maintenance, the control sleeve 31 is held by hand, and then the control sleeve 31 is pulled downward, and then the connecting tube 22 cooperates with the one-way tube 12 to compress the first spring 28 installed on one side, and at the same time, the receiving groove 27 moves with the control sleeve 31 and the connecting tube 22. When the position of the receiving groove 27 corresponds to the position of the through groove 26, the first spring 28 is just compressed to the limit, and then the control sleeve 31 is continued to be pulled, at this time, the limit ball 25 is squeezed by the side wall of the slot 24, and due to the limit The ball 25 is a spherical body, so the limiting ball 25 will roll into the accommodating groove 27 through the through groove 26, and then the limiting sleeve 23 and the connecting pipe 22 will be pulled out of the one-way tube 12 together. In this process, the slider 29 arranged on the outside of the limiting sleeve 23 will slide in the slide groove 30 opened in the one-way tube 12, and the slider 29 and the slide groove 30 play a role of limiting and guiding, preventing the limiting sleeve 23 from rotating, and can achieve accurate engagement between the limiting ball 25 and the slot 24. After the equipment maintenance is completed, refer to the above operation to connect the conveying equipment and the spraying equipment together.
[0041] In summary, when the overall equipment is in use or running: first, place the machine tool 1 on the ground. When the ground is uneven, rotate the adjusting screw 2 in the corresponding direction. Since the adjusting screw 2 and the fixing nut 3 are movably connected by threads, and the fixing nut 3 is fixedly installed on the machine tool 1, the adjusting screw 2 will move up and down accordingly when rotating. When the anti-skid pad 19 set at the bottom end of the support block 4 is flush with the ground, stop rotating the adjusting screw 2, and then refer to this operation to level the machine tool 1, so as to ensure the stability of the machine tool 1 during use, and the anti-skid pad 19 can increase the friction between the equipment and the ground, further enhancing the stability of the machine tool 1 during use, and then place the parts to be processed on the conveying assembly 5, and drive them through the power element in the conveying assembly 5, so as to convey the parts to be sprayed into the protective bin 6, and then temporarily turn off the power element, and then use the external conveying equipment to convey the paint through the conveying pipe 7 to the spraying assembly set in the protective bin 6, and then spray the paint to zero. The surface of the part, in this process, the protective curtains 18 arranged on both sides of the protective bin 6 can prevent the paint from being sprayed onto the outside of the equipment. When it is necessary to adjust the input flow rate of the delivery pipe 7, the adjusting sleeve 14 is rotated in the corresponding direction, and the sliding blocks 20 arranged on both sides of the adjusting sleeve 14 will slide in the corresponding sliding grooves 21 respectively, and then the unlocking sleeve will drive the corresponding limiting rod 9 to rotate through the limiting frame 8 with a special structural design. Due to the special structural design of the spiral groove 13 and the existence of the guide ball 16, when the limiting rod 9 drives the blocking frame 10 to rotate, the blocking frame 10 will move upward at the same time, and then the exposed area of the water tank 11 will become larger and larger, so as to achieve the purpose of adjusting the input flow rate of the delivery pipe 7. When it is adjusted to the appropriate position, stop rotating the unlocking sleeve. In this process, the second spring 15 can ensure the stability of the movement of the blocking frame 10, and the third spring 17 can ensure the fit between the guide ball 16 and the spiral groove 13, and can also apply pressure when it is not rotating to prevent it from rotating easily.
[0042] When the spraying equipment needs to be disconnected from the external conveying equipment for replacement and maintenance, the control sleeve 31 is held by hand, and then the control sleeve 31 is pulled downward, and then the connecting tube 22 cooperates with the one-way tube 12 to compress the first spring 28 installed on one side, and at the same time, the receiving groove 27 moves with the control sleeve 31 and the connecting tube 22. When the position of the receiving groove 27 corresponds to the position of the through groove 26, the first spring 28 is just compressed to the limit, and then the control sleeve 31 is continued to be pulled, at this time, the limiting ball 25 is squeezed by the side wall of the slot 24, and because the limiting ball 2 5 is a sphere, so the limiting ball 25 will roll into the receiving groove 27 through the through groove 26, and then the limiting sleeve 23 and the connecting pipe 22 will be pulled out of the one-way tube 12 together. In this process, the slider 29 arranged on the outside of the limiting sleeve 23 will slide in the slide groove 30 opened in the one-way tube 12, and the slider 29 and the slide groove 30 play a role of limiting and guiding, preventing the limiting sleeve 23 from rotating, and can achieve accurate engagement between the limiting ball 25 and the card slot 24. When the equipment maintenance is completed, refer to the above operation to connect the conveying equipment and the spraying equipment together.
