Description

Technical Field

[0001] This utility model relates to the technical field of spray coating production lines, and in particular to a workpiece conveying and positioning fixture for a spray coating production line. Background Technology

[0002] A spray coating production line is an integrated industrial equipment system, mainly used for efficient and uniform coating of various workpiece surfaces. It is widely used in industries such as automobile manufacturing, home appliances, electronics, and furniture. When coating workpiece surfaces, spray coating production lines often require the use of positioning fixtures to position the workpieces.

[0003] When using positioning fixtures to position workpieces, traditional fixtures can only fix the workpiece at a certain angle. This prevents the remaining surfaces of the workpiece from being effectively coated during subsequent painting. The common solution is to wait for the coated surface to dry before remounting the workpiece on the fixture and repainting. While this solves the problem of ineffective coating of the remaining surfaces, it requires a significant amount of time to allow the workpiece to dry, thus impacting production efficiency.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] The following describes a workpiece conveying and positioning fixture for a spraying production line according to an embodiment of the present invention, with reference to the accompanying drawings.

[0019] like Figures 1-5 As shown in the figure, a workpiece conveying and positioning fixture for a spraying production line according to an embodiment of the present invention includes: a chain conveyor belt 1, a fixture 2, and a flipping mechanism 3.

[0020] The clamp 2 is mounted on the chain conveyor belt 1, and the flipping mechanism 3 includes a rack 32, a limiting post 33, a mounting block 34, a gear 35, a connecting rod 36, a mounting base 37, a second power source 38, and a buffer assembly 39.

[0021] The fixture 2 has an inner wall with a mounting groove 31, a rack 32 is installed in the mounting groove 31, a limiting post 33 is installed in the fixture 2, and the other end of the limiting post 33 passes through the mounting block 34 and is connected to the inner wall of the fixture 2. A gear 35 is installed in the mounting groove 31, a connecting rod 36 is installed on the gear 35, and the other end of the connecting rod 36 passes through the mounting block 34 and is connected to the mounting seat 37. The output shaft of the second power source 38 passes through the outer wall of the fixture 2 and is connected to the side wall of the mounting block 34. A buffer assembly 39 is installed on the fixture 2. A sliding groove 310 is provided in the outer shell 21, and a slider 311 is provided on the outer wall of the mounting block 34.

[0022] The fixture 2 includes a housing 21, a first power source 22, a mounting box 23, a mounting shell 24, and a power supply 25.

[0023] The first power source 22 is located inside the outer casing 21, the mounting box 23 is located on the outer wall of the outer casing 21, the mounting shell 24 is located at the bottom of the mounting box 23, and the side wall of the mounting shell 24 is connected to the outer casing 21. The power supply 25 is located inside the mounting shell 24.

[0024] It should be noted that the first power source 22 and the second power source 38 described in this embodiment are cylinders. Their main functions are as follows: the first power source 22 is symmetrically arranged on both sides of the outer shell 21 to fix the workpiece, while the second power source 38 controls the mounting block 34 to slide back and forth inside the outer shell 21.

[0025] Specifically, when multi-sided spraying is required on some workpieces, the workpieces are fixed by the first power source 22 inside the housing 21. Then, the two second power sources 38 installed on the same side of the housing 21 are activated. The second power sources 38 push the mounting block 34 to slide along the slide groove 310 through the output shaft and pull it back after the mounting block 34 contacts the inner wall of the housing 21. At this time, the gear 35 outside the mounting block 34 will mesh with the rack 32 in the mounting groove 31 and rotate. The first power source 22 used by the fixture 2 is installed on the mounting base 37 connected to the gear 35 through the connecting rod 36. So when the gear 35 rotates, the mounting base 37 will drive the first power source 22 to rotate synchronously. At this time, the workpiece fixed by the first power source 22 will rotate together with the rotation of the first power source 22, so that the workpiece can be sprayed on multiple sides.

[0026] In one embodiment of this application, such as Figure 4 As shown, the buffer assembly 39 includes a mounting plate 391, a connecting pipe 392, a sleeve 393, a first spring 394, and a fixed shell 395.

[0027] The mounting plate 391 is connected to the output shaft of the first power source 22. The connecting pipe 392 is mounted on the mounting plate 391. The sleeve 393 is fitted on the outside of the connecting pipe 392. The first spring 394 is mounted inside the connecting pipe 392 and is connected to the inner wall of the sleeve 393. The fixing shell 395 is mounted on the sleeve 393 and a buffer pad 396 is provided inside the fixing shell 395.

[0028] Specifically, when the first power source 22 is used to fix the workpiece, as the output shaft of the first power source 22 is pushed out, the mounting plate 391 installed on the output shaft will push the fixing shell 395 to contact the workpiece through the connecting pipe 392 and the sleeve 393. At the same time, as the first power source 22 is gradually pushed out, the first spring 394 in the connecting pipe 392 will be gradually compressed and a thrust will be applied towards the workpiece, thereby preventing the first power source 22 from being pushed out too much while strengthening the fixation of the workpiece. Meanwhile, the buffer pad 396 enhances the contact between the fixing shell 395 and the workpiece.

[0029] In one embodiment of this application, such as Figure 5 As shown, a fixing component 4 is provided at the bottom of the outer casing 21.

[0030] The fixing component 4 includes a connecting block 41, a mounting hole 42, a second spring 43, a connecting rod 44, and a support plate 45.

[0031] The connecting block 41 is located at the bottom of the outer shell 21. The outer wall of the connecting block 41 is provided with mounting holes 42. The second spring 43 is located in the mounting holes 42. The other end of the second spring 43 is connected to one end of the connecting rod 44. The support plate 45 is connected to the other end of the connecting rod 44. A gasket 46 is provided on the support plate 45.

[0032] Specifically, when using the chain conveyor belt 1 to transport the positioning clamp 2, the clamp 2 is tilted so that the support plate 45 with the gasket 46 installed on one side of the connecting block 41 contacts the inner wall of the gap of the chain conveyor belt 1, and the connecting rod 44 on the side of the support plate 45 is pushed into the mounting hole 42. Then, the tilted clamp 2 is straightened and the support plate 45 is released. At this time, under the action of the second spring 43, the support plates 45 on both sides of the support plate 45 will be pushed out, so that the clamp 2 is fixed on the chain conveyor belt 1.

[0033] Working Principle: When multi-sided spraying of a workpiece is required, the workpiece is fixed by the first power source 22 inside the housing 21. Then, the two second power sources 38 installed on the same side of the housing 21 are activated. The second power sources 38 push the mounting block 34 along the slide groove 310 through the output shaft. After the mounting block 34 contacts the inner wall of the housing 21, it is pulled back. At this time, the gear 35 outside the mounting block 34 will mesh with the rack 32 in the mounting groove 31 and rotate. The first power source 22 used by the fixture 2 is installed on the mounting base 37 connected to the gear 35 through the connecting rod 36. Therefore, when the gear 35 rotates, the mounting base 37 will synchronously drive the first power source 22 to rotate. At this time, the workpiece fixed by the first power source 22 will rotate together with the rotation of the first power source 22, so that the workpiece can be sprayed on multiple sides. When the first power source 22 is used to fix the workpiece, the first power source 22 rotates along with the first power source 22. As the output shaft of the first power source 22 extends, the mounting plate 391 installed on the output shaft pushes the fixed shell 395 to contact the workpiece through the connecting pipe 392 and the sleeve 393. At the same time, as the first power source 22 is gradually extended, the first spring 394 in the connecting pipe 392 is gradually compressed and a thrust is applied towards the workpiece, thereby preventing the first power source 22 from extending too far and strengthening the fixation of the workpiece. Meanwhile, the buffer pad 396 enhances the contact between the fixed shell 395 and the workpiece. When the positioning fixture 2 is conveyed by the chain conveyor belt 1, the fixture 2 is tilted so that the support plate 45 with the gasket 46 installed on one side of the connecting block 41 contacts the inner wall of the gap of the chain conveyor belt 1, and the connecting rod 44 on the side of the support plate 45 is pushed into the mounting hole 42. At this time, the tilted fixture 2 is straightened and the support plate 45 is released. At this time, under the action of the second spring 43, the support plates 45 on both sides of the support plate 45 will be pushed out, thereby fixing the fixture 2 on the chain conveyor belt 1.
