Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing, and specifically relates to a positioning device for automotive parts manufacturing. Background Technology

[0002] Automobiles are composed of hundreds or thousands of parts. Automobile parts processing consists of various units that make up the whole automobile parts processing and products that serve automobile parts processing. During the processing of automobile parts, clamping and positioning devices are needed to position and fix the automobile parts. In the process of automobile production and processing, welding is often required. However, the existing operating technology often requires the operator to frequently move the working position to adjust the welding angle during the welding process, and it is not possible to effectively fix the parts to be welded during the welding process.

[0003] According to Chinese Patent No. CN214025365U, a positioning device for automobile parts production is disclosed, including a fixed base plate. An adjustment connector is movably connected to the upper surface of the fixed base plate. A first mounting hole is opened in the middle of the upper surface of the adjustment connector. The inner wall of the first mounting hole is provided with threads. A placement plate is threadedly connected to the inner wall of the first mounting hole through an adjustment screw. Limit bolts are provided at both ends of the upper surface of the placement plate. A first connecting plate is movably connected to the outer wall of the limit bolt. A second connecting plate is movably connected to the end of the first connecting plate away from the limit bolt through a rivet. A connecting hole is opened at the end of the second connecting plate away from the first connecting plate. A limit rod is movably connected to the inner wall of the connecting hole. A limit plate is fixedly connected to the side wall of the limit rod. A baffle is provided on the side of the limit plate away from the limit rod. The position of the parts on the placement plate is controlled by the cooperation of the placement plate, the adjustment screw, the baffle, the first connecting plate and the second connecting plate.

[0004] As can be seen from the above structure, the position of the parts on the placement plate is controlled by the cooperation of the placement plate, adjusting screw, baffle, first connecting plate and second connecting plate. In order to make the entire positioning device more stable, however, as can be seen from the above figure and text, the positioning stability is not good by limiting only by the baffle. At the same time, when machining and positioning circular parts, slippage is easy to occur. Therefore, a positioning device that can be used to machine circular parts is proposed. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a positioning device for automobile parts production to solve the problems raised in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A positioning device for automotive parts manufacturing includes a bracket, a lifting assembly at the lower end of the bracket, and a positioning assembly on the outer side of the lifting assembly. The positioning assembly includes a positioning seat, a positioning disk fixedly connected to the upper end of the positioning seat, and multiple positioning slots on the upper end of the positioning disk. Positioning screws are rotatably connected inside each positioning slot, and threaded components are threaded onto the outer surface of each positioning screw. A clamping block is fixedly connected to the upper end of each threaded component. A driven bevel gear is fixedly connected to the other end of each positioning screw. A drive motor is fixedly connected to the lower end of the positioning seat, and a driving bevel gear is fixedly connected to the output shaft of the drive motor. The driving bevel gear and the driven bevel gear mesh with each other.

[0008] As a preferred technical solution, the lifting assembly includes a lifting screw rotatably connected to the upper diagonal of the bracket. The lifting screw is threadedly connected to the positioning seat. The positioning seat has lifting screw holes at each diagonal, and the lifting screw holes are threadedly connected to the lifting screw.

[0009] As a preferred technical solution, a lifting motor is fixedly connected to the lower end of the bracket, a drive gear is fixedly connected to the output shaft of the lifting motor, and a driven gear is rotatably connected to the lower end of the bracket. The upper ends of the drive gear and the driven gear both pass through the bracket and are fixedly connected to the lifting screw. The drive gear and the driven gear are connected to each other through a transmission belt.

[0010] As a preferred technical solution, a limiting seat is fixedly connected to each diagonal part of the upper end of the bracket, a limiting rod is fixedly connected to the upper end of each limiting seat, and a limiting hole is opened at each diagonal part of the positioning seat. The limiting rod and the limiting hole are slidably inserted into each other.

[0011] As a preferred technical solution, the upper end of each limiting rod is threadedly connected to a limiting plate, the upper end of each limiting rod is provided with a fixing screw hole, and the lower end of each limiting plate is fixedly connected with a fixing screw, the fixing screw and the fixing screw hole being threadedly connected to each other.

[0012] As a preferred technical solution, the outer side of the positioning plate is fixedly connected with multiple mounting edges, and the surface of each mounting edge is provided with mounting holes. Mounting screws are inserted into the interior of each mounting hole, and the mounting screws pass through the mounting holes and are threadedly connected to the positioning seat.

[0013] As a preferred technical solution, the lower end of the bracket is provided with a groove, and an electric push rod is fixedly connected inside the groove. The other end of the electric push rod is fixedly connected with a rubber pad, and the rubber pad is movably connected to the corner of the groove.

[0014] In summary, the present invention has the following main advantages:

[0015] First, this utility model, through its positioning component, allows for the placement of round automotive parts on the upper end of a fixed disc, located inside the clamping block. The rotation of a drive motor drives a bevel gear, which in turn rotates the driven support wheel. This rotation, in turn, drives the positioning screw, causing the threaded component to move. This movement of the threaded component pulls the clamping blocks closer together, effectively clamping the parts. Furthermore, the use of multiple clamping blocks at multiple angles enhances the clamping effect and stability.

[0016] Secondly, this utility model, through its lifting component, allows for height adjustment of the positioning component during use. By controlling the lifting motor to rotate, the driving gear rotates. Under the action of the transmission belt, the driven gear rotates as well. Thus, when the driven gear and the driving gear rotate simultaneously, they respectively drive the lifting screw to rotate. The lifting screw is threadedly connected to the positioning seat through a lifting screw hole, allowing the positioning seat to move under the rotation of the lifting screw. This enables height adjustment of the positioning component, increasing the practicality of the device. Attached Figure Description

[0022] Example

[0023] refer to Figures 1 to 4 This embodiment of a positioning device for automotive parts production includes a bracket 1. A lifting assembly 6 is provided at the lower end of the bracket 1, and a positioning assembly 2 is provided on the outer side of the lifting assembly 6. The positioning assembly 2 includes a positioning seat 21. A positioning disk 22 is fixedly connected to the upper end of the positioning seat 21. Multiple positioning grooves 23 are provided on the upper end of the positioning disk 22. Positioning screws 24 are rotatably connected inside the positioning grooves 23. Threaded parts 25 are threadedly connected to the outer surface of the positioning screws 24. Clamping blocks 26 are fixedly connected to the upper end of the threaded parts 25. A driven bevel gear 29 is fixedly connected to the other end of the positioning screws 24. A drive motor 28 is fixedly connected to the lower end of the positioning seat 21. An active bevel gear 27 is fixedly connected to the output shaft of the drive motor 28. The active bevel gear 27 and the driven bevel gear 29 are meshed with each other.

[0024] refer to Figures 2-4 The lifting assembly 6 includes a lifting screw 61 rotatably connected to the upper diagonal of the bracket 1. The lifting screw 61 is threadedly connected to the positioning seat 21. Lifting screw holes 62 are provided at opposite corners of the positioning seat 21, and the lifting screw holes 62 are threadedly connected to the lifting screw 61. A lifting motor 63 is fixedly connected to the lower end of the bracket 1. A drive gear 64 is fixedly connected to the output shaft of the lifting motor 63. A driven gear 65 is rotatably connected to the lower end of the bracket 1. The upper ends of both the drive gear 64 and the driven gear 65 pass through the bracket 1 and are fixedly connected to the lifting screw 61. 5. The components are interconnected by a transmission belt 66. By controlling the rotation of the lifting motor 63, the driving gear 64 is driven to rotate. Under the action of the transmission belt 66, the driving gear 64 can drive the driven gear 65 to rotate together. Thus, when the driven gear 65 and the driving gear 64 rotate simultaneously, they respectively drive the lifting screw 61 to rotate. The lifting screw 61 is threadedly connected to the positioning seat 21 through the lifting screw hole 62. Thus, the rotation of the lifting screw 61 can drive the positioning seat 21 to move, thereby enabling the adjustment of the height of the positioning component 2.

[0025] refer to Figure 2 Each of the upper diagonal ends of the bracket 1 is fixedly connected to a limiting seat 7, and each of the upper ends of the limiting seat 7 is fixedly connected to a limiting rod 8. Each of the diagonal ends of the positioning seat 21 is provided with a limiting hole, and the limiting rod 8 and the limiting hole are slidably inserted into each other. The limiting seat 7 can prevent the positioning seat 21 from moving to the lowest end and hitting the drive motor 28. Under the action of the limiting rod 8, the positioning seat 21 can be limited to avoid shaking during movement.

[0026] refer to Figure 1 and Figure 2The upper end of each limiting rod 8 is threadedly connected to a limiting plate 11, and each limiting rod 8 has a fixing screw hole 9. The lower end of each limiting plate 11 is fixedly connected to a fixing screw 10, and the fixing screw 10 and the fixing screw hole 9 are threadedly connected to each other. The limiting plate 11 can limit the positioning seat 21, preventing the positioning component 2 from falling off due to excessive movement. At the same time, the threaded installation makes it easier to disassemble the limiting plate 11 and facilitates the disassembly of the positioning component 2.

[0027] refer to Figure 1 The outer side of the positioning plate 22 is fixedly connected with multiple mounting edges 3. The surface of each mounting edge 3 is provided with mounting holes 4. Mounting screws 5 are inserted into the mounting holes 4. The mounting screws 5 pass through the mounting holes 4 and are threadedly connected to the positioning seat 21. The mounting screws 5 make it easy to remove the positioning plate 22, which makes it more convenient to replace or maintain the equipment.

[0028] refer to Figure 4 The lower end of the bracket 1 has a groove 12, and an electric push rod 13 is fixedly connected inside the groove 12. The other end of the electric push rod 13 is fixedly connected to a rubber pad 14, and the rubber pad 14 is movably connected to the corner of the groove 12. By controlling the electric push rod 13, the rubber pad 14 is moved into the groove 12. However, during the movement of the rubber pad 14, the air pressure at the bottom of the rubber pad 14 decreases, thereby generating suction, which can firmly fix the device.

[0029] Operating principle and advantages: During use, the device is moved to a suitable position and placed on a table. The electric push rod 13 is then controlled to move the rubber pad 14 into the groove 12. As the rubber pad 14 moves, the air pressure at its bottom decreases, generating suction and firmly securing the device. The height of the positioning component 2 can be adjusted as needed. The lifting motor 63 rotates, driving the drive gear 64. The rotation of the drive gear 64, under the action of the transmission belt 66, drives the driven gear 65 to rotate. When the driven gear 65 and the drive gear 64 rotate simultaneously, they respectively drive the lifting screw 61 to rotate. The lifting screw 61 is threaded to the positioning seat 21 through the lifting screw hole 62. The rotation of the lifting screw 61 causes the positioning seat 21 to move, thereby adjusting the height of the positioning component 2. After adjustment, the round automotive parts are placed on the upper end of the fixed plate, inside the clamping block 26. The drive motor 28 is then controlled to rotate, which in turn drives the bevel gear to rotate. The drive bevel gear 27 rotates, which in turn drives the driven support wheel that meshes with it to rotate. This, in turn, drives the positioning screw 24 to rotate, which in turn drives the threaded part 25 to move. The movement of the threaded part 25 causes the clamping block 26 to move closer together, thus clamping the parts when the clamping blocks 26 move closer together. This structure provides more stable clamping and a better clamping effect.
