[0024] Embodiment

[0025] As Figures 1-4 shown, a new positioning device for automobile painting production includes a base 1;

[0026] A vertical plate 2, a mounting seat 4 and a center seat 5 are vertically arranged on the base 1. A slot is provided on the vertical plate 2, and a clamping assembly 3 is rotatably arranged in the slot; A rotating assembly 6 is jointly assembled on the mounting seat 4 and the center seat 5;

[0027] An installation hole is provided on the center seat 5. The rotating assembly 6 includes a transmission shaft 65 rotatably arranged on the center seat 5, and one end of the transmission shaft 65 is connected with a guide rod cylinder 67;

[0028] The clamping assembly 3 includes a positioning shaft 31 rotatably arranged on the vertical plate 2. One end of the positioning shaft 31 is connected with a positioning seat 32. A plurality of sliding grooves 33 are circumferentially provided on the positioning seat 32 along its center, and a clamping plate 34 is slidably arranged in each sliding groove 33.

[0029] In this embodiment, in actual use, through the mutual movement cooperation of multiple components in the rotating assembly 6 provided, the entire guide rod cylinder 67 can rotate on the center seat 5. When the user completes the clamping of the automobile workpiece through the operation of the clamping assembly 3, at this time, when the guide rod cylinder 67 rotates, the user controls the radial movement of the output end of the guide rod cylinder 67 until it abuts against the side wall of the workpiece. At this time, through the limit of the workpiece by the guide rod cylinder 67 and the rotational cooperation between the bearing member 21 and the positioning shaft 31, finally, the automobile workpiece can rotate integrally with the clamping assembly 3. By rotating the workpiece, it can ensure that the sprayed paint evenly covers all surfaces of the workpiece, making the spraying process more uniform. At the same time, by rotating the workpiece, more surfaces of the workpiece can be coated in a shorter time. The spraying worker can rotate the workpiece to adapt to different angles and curved surfaces, thereby more efficiently completing the painting task, reducing the painting time and labor cost, and improving the production efficiency.

[0030] Further, the user places the workpiece to be fixed between several clamping plates 34, and then unscrews the positioning bolt 35, so that the clamping plates 34 can slide in the sliding grooves 33 until several clamping plates 34 tightly abut against the side wall of the workpiece. At this time, by performing secondary positioning on the clamping plates 34, the clamping and limiting of the workpiece can be completed by several clamping plates 34. The slidably arranged clamping plates 34 can also clamp automotive workpieces of different sizes, improving the positioning range of the present application.

[0031] Specifically, referring to Figures 2-4 , the clamping plate 34 is arranged in a U shape and one side slides in the sliding groove 33.

[0032] In this embodiment, during actual use, the user places the workpiece to be fixed between several clamping plates 34, and then slides and adjusts the clamping plates 34 in the sliding grooves 33 until several clamping plates 34 tightly abut against the side wall of the workpiece. At this time, the user performs secondary positioning on the clamping plates 34, and the clamping and limiting of the automotive workpiece can be completed by several clamping plates 34.

[0033] Specifically, referring to Figure 4 , a plurality of threaded holes are formed in the positioning seat 32, each threaded hole corresponds to one of the sliding grooves 33 respectively, a positioning bolt 35 is rotatably arranged in the threaded hole, and the end of the positioning bolt 35 penetrates through the threaded hole and abuts against the side wall of an adjacent clamping plate 34.

[0034] In this embodiment, through the threaded connection between the threaded holes on the set positioning seat 32 and the positioning bolts 35, when the user unscrews the positioning bolts 35 from the positioning seat 32 so that the positioning bolts 35 are disengaged from the limitation of the clamping plates 34, the set clamping plates 34 can then slide in the sliding grooves 33. When the user adjusts the clamping plates 34 to clamp the workpiece, at this time, the positioning bolts 35 are screwed into the positioning seat 32 again until the ends of the positioning bolts 35 tightly abut against the side walls of the clamping plates 34, and the secondary positioning of the clamping plates 34 can be completed by the positioning bolts 35.

[0035] Specifically, referring to Figures 1-3 , a bearing member 21 is assembled in the notch formed in the vertical plate 2, the positioning shaft 31 is rotationally matched with the bearing member 21, and the output end of the guide rod cylinder 67 is arranged opposite to the clamping assembly 3 and is on the same axis as the positioning shaft 31.

[0036] In this embodiment, during actual use, after the user completes the clamping of the automotive workpiece by operating the clamping assembly 3, the user then controls the radial movement of the output end of the guide rod cylinder 67 until it abuts against the side wall of the workpiece. Through the limiting of the workpiece by the guide rod cylinder 67 and the rotational cooperation between the bearing member 21 and the positioning shaft 31, when the entire guide rod cylinder 67 rotates, the set clamping assembly 3 can rotate synchronously with the workpiece. By rotating the workpiece, more surfaces of the workpiece can be coated in a shorter time, thereby more efficiently completing the painting task.

[0037] Specifically, referring to Figures 1-3 , a rotary motor 61 is assembled and provided on the mounting seat 4. The output end of the rotary motor 61 is connected to a transmission shaft 62, and a lower shaft wheel 63 is sleeved outside the transmission shaft 62.

[0038] In this embodiment, during use, the user can connect a power supply to the rotary motor 61, so that the rotary motor 61 drives the transmission shaft 62 and the lower shaft wheel 63 to rotate.

[0039] Specifically, referring to Figures 1-3 , an upper wheel 66 is sleeved outside the transmission shaft 65, and a connecting belt 64 is tensioned and connected outside the lower shaft wheel 63 and the upper wheel 66.

[0040] In this embodiment, during the rotation operation, when the lower shaft wheel 63 rotates, through the tensioned connection of the connecting belt 64 to the upper wheel 66, the transmission shaft 65 can rotate following the lower shaft wheel 63. At this time, through the rotation of the transmission shaft 65 within the center seat 5, by the rotation of the transmission shaft 65, the guide rod cylinder 67 is driven to rotate.

[0041] The novel positioning device for automotive painting production of the present utility model:

[0042] First step: During actual use, when the user positions the automotive workpiece, by placing the workpiece to be fixed between several clamping plates 34, and then screwing out the positioning bolt 35, the clamping plates 34 can slide within the sliding groove 33 until several clamping plates 34 abut against the side wall of the workpiece. At this time, the user screws the positioning bolt 35 tightly onto the positioning seat 32 until the end of the positioning bolt 35 abuts against the side wall of the clamping plate 34. At this time, the secondary positioning of the clamping plate 34 can be achieved, and at the same time, the clamping and limiting of the workpiece are completed through several clamping plates 34;

[0043] Step 2: After the clamping component 3 clamps the workpiece, the user can then perform the spraying operation on the automotive workpiece. When the workpiece is being sprayed, the user can then connect the power supply to the rotary motor 61, causing the rotary motor 61 to drive the transmission shaft 62 and the lower pulley 63 to rotate. When the lower pulley 63 rotates, through the tension connection of the connecting belt 64 to the upper pulley 66, the transmission shaft 65 can follow and rotate. Furthermore, through the rotation of the transmission shaft 65, the guide rod cylinder 67 is driven to rotate.

[0044] Step 3: When the guide rod cylinder 67 rotates, the user connects the air source to the guide rod cylinder 67, causing the output end of the guide rod cylinder 67 to move radially until it tightly abuts against the side wall of the workpiece. At this time, through the limiting of the workpiece by the guide rod cylinder 67, in cooperation with the rotation of the guide rod cylinder 67 and the rotational cooperation between the bearing member 21 and the positioning shaft 31, the automotive workpiece can ultimately be driven to rotate integrally with the clamping component 3. By controlling the number of rotation cycles, the user can complete the spraying operation on different machining surfaces of the automotive workpiece.
