Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to an automatic embedding device for automotive mudguard studs. Background Technology

[0002] In the automotive manufacturing industry, the rear subframe mudguard is a key component that protects the vehicle chassis and sides from impacts from mud, stones, and other debris. Its assembly quality directly affects the vehicle's driving safety and appearance integrity.

[0003] The connection between mudguards and the vehicle body typically relies on studs. These studs must be precisely embedded into the pre-set mounting holes in the mudguard to form a stable connection. Therefore, the accuracy, efficiency, and consistency of stud embedding are crucial factors determining the production capacity and product qualification rate of the automotive mudguard assembly line. Currently, the embedding of mudguard studs in automotive production is generally done using manual rivet guns. During operation, operators hold the rivet gun, align the stud with the mudguard mounting hole, and press it in. This method has significant limitations: Firstly, manual positioning relies on operator experience, and visual deviations and hand tremors can easily lead to stud misalignment, resulting in excessive clearance between the mounting hole and the stud or stud tilting. Subsequent assembly requires rework and adjustment, reducing production efficiency and potentially causing cracking of the mudguard's plastic substrate due to repeated operations, increasing the defect rate. Secondly, manual operation requires maintaining a bent-over posture while holding heavy objects, which can easily lead to muscle strain for operators over long periods. Furthermore, the impact force generated during rivet gun operation poses a safety hazard if not handled properly. Utility Model Content

[0004] To solve the above problems, this utility model provides an automatic embedding device for automobile mudguard studs.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic embedding device for automobile mudguard studs, comprising a cabinet with an opening on one side, a workbench inside the cabinet, a mudguard fixing fixture and several fixing components for fixing the mudguard fixing fixture on the workbench, a crossbeam on the top of the cabinet, two sets of sliding beams slidably arranged along the length of the crossbeam, a first electric slide table arranged horizontally on the sliding beam, a sliding seat fixedly arranged on the slide base of the first electric slide table, a second electric slide table arranged vertically on the sliding seat, a connecting seat arranged on the slide base of the second electric slide table, an automatic rivet gun fixedly arranged on the connecting seat, and a feeding machine for feeding studs to the automatic rivet gun on the workbench.

[0006] By adopting the above technical solution, a workbench, mudguard fixing fixtures, and fixing components are set up to place and fix the mudguard structure. Then, a crossbeam, sliding beam, first electric slide, sliding seat, second electric slide, connecting seat, automatic rivet gun, and feeding machine are set up. The feeding machine is used in conjunction with the automatic rivet gun to feed the studs to the automatic rivet gun. The sliding beam, first electric slide, sliding seat, second electric slide, and connecting seat work together to realize the movement of the automatic rivet gun in the three directions of X-axis, Y-axis, and Z-axis, so that the automatic rivet gun can move in the entire workbench area. In this way, by designing a good movement path, the automatic rivet gun can automatically complete the stud embedding at each point, with accurate positioning and high work efficiency.

[0007] Furthermore, two baffles are arranged parallel to each other on the workbench, and the area between the two baffles is used to place the mudguard fixing fixture. Two sets of fixing components are arranged at intervals on the side of the baffle away from the mudguard fixing fixture.

[0008] By adopting the above technical solution, two baffles are set to limit the mudguard fixing fixture, ensuring the accurate installation position of the mudguard fixing fixture. Then, four sets of fixing components on the outside of the two baffles are used to fix the mudguard fixing fixture, ensuring the stability of the mudguard fixing fixture.

[0009] The further fixed component includes a fixed block set on the workbench, a mounting frame set on the fixed block, a fixed frame set inside the mounting frame, a connecting plate set on the fixed frame, one end of the connecting plate located outside the baffle and rotatably set inside the fixed frame, the other end located inside the baffle and set with a fixed pressure rod at the end, the mounting frame extending outward from the baffle and rotatably set with a clamping cylinder, a rotating frame hinged in the middle of the connecting plate, and the end of the rotating frame away from the connecting plate hinged to the end of the piston rod of the clamping cylinder.

[0010] By adopting the above technical solution, a fixing block, mounting frame, fixing bracket, connecting plate, fixing pressure rod, clamping cylinder, and rotating frame are set up. The piston rod of the clamping cylinder pulls the rotating frame, causing the connecting plate to rotate around the axis between it and the fixing bracket, thereby driving the fixing pressure rod at the end of the connecting plate to perform downward or upward movements.

[0011] Furthermore, a limiting frame is rotatably mounted on the fixed frame. The end of the limiting frame away from the fixed frame is hinged to the end of the piston rod of the pressing cylinder, and the hinged end of the limiting frame, the hinged end of the rotating frame, and the end of the piston rod of the pressing cylinder are coaxially hinged.

[0012] By adopting the above technical solution and setting a limiting frame, the upward range is limited when the pressing cylinder drives the fixed pressure rod to move.

[0013] Furthermore, the mudguard fixing fixture includes a base plate, on which a plurality of support blocks that cooperate with the mudguard are provided. On the base plate, a plurality of clamping seats are provided around the mudguard placement area. Clamping cylinders are provided on the clamping seats. The piston cylinder of the clamping cylinder passes upward through the clamping seat and is provided with a clamping plate at its end. A clamping block is provided at the bottom of the clamping plate at the end away from the clamping seat.

[0014] By adopting the above technical solution, a base plate, a support block, a clamping cylinder, a clamping plate, and a clamping block are set up. The support block is used to support the mudguard, and then the clamping cylinder drives the clamping plate and clamping block to move downward to clamp and fix the mudguard.

[0015] Furthermore, a control cabinet is installed inside the cabinet below the workbench, and a control panel is installed on one side of the cabinet near the opening.

[0016] By adopting the above technical solution, a control cabinet and control panel are set up to facilitate program control and parameter setting.

[0017] In summary, this utility model has the following beneficial effects: In this application, a workbench, a mudguard fixing fixture, and a fixing component are set up to place and fix the mudguard structure. Then, a crossbeam, a sliding beam, a first electric slide, a sliding seat, a second electric slide, a connecting seat, an automatic rivet gun, and a feeding machine are set up. The feeding machine is used in conjunction with the automatic rivet gun to feed the studs to the automatic rivet gun. The sliding beam, the first electric slide, the sliding seat, the second electric slide, and the connecting seat work together to realize the movement of the automatic rivet gun in the three directions of X-axis, Y-axis, and Z-axis, so that the automatic rivet gun can move in the entire workbench area. In this way, by designing a good movement path, the automatic rivet gun can automatically complete the stud embedding at each point, with accurate positioning and high work efficiency.

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] like Figure 1-6 As shown in the figure, this application discloses an automatic embedding device for automobile mudguard studs, including a cabinet 10. One side of the cabinet 10 has an opening to facilitate the entry and exit of materials. A workbench 20 is provided inside the cabinet 10. The workbench 20 is provided with a mudguard fixing fixture 30 and several fixing components 40. The mudguard fixing fixture 30 is used to place and fix the mudguard, and the fixing components 40 are used to fix the mudguard fixing fixture 30.

[0022] Specifically, the mudguard fixing fixture 30 includes a base plate 31, on which several support blocks 32 are provided to cooperate with the mudguard. The support blocks 32 are used to support and position the mudguard. Several clamping seats 33 are provided on the base plate 31 around the mudguard placement area. Clamping cylinders 34 are provided on the clamping seats 33. The piston cylinder of the clamping cylinder 34 passes upward through the clamping seat 33 and is provided at the end of the clamping plate 35. A clamping block 36 is provided at the bottom of the clamping plate 35 away from the clamping seat 33. In use, the mudguard is first placed on the support block 32 and positioned according to the support block 32 to ensure accurate placement of the mudguard. Then, the clamping cylinder 34 is activated to drive the clamping plate 35 and clamping block 36 to move downward. The clamping block 36 contacts the upper surface of the mudguard and presses down, thereby pressing and fixing the mudguard onto the support block 32.

[0023] Two baffles 21 are arranged parallel to each other on the workbench 20. The area between the two baffles 21 is used to place the mudguard fixing fixture 30. That is, the distance between the two baffles 21 is the same as the length of the base plate 31. In this way, the base plate 31 of the mudguard fixing fixture 30 is placed between the two baffles 21, which can both position the mudguard fixing fixture 30 and restrict its movement on the workbench 20.

[0024] A further configuration involves two sets of fixing components 40 spaced apart on the side of the baffle 21 away from the mudguard fixing fixture 30. That is, there are a total of four sets of fixing components 40, which together fix both sides of the mudguard fixing fixture 30, ensuring its stability. Specifically, each fixing component 40 includes a fixing block 41 mounted on the workbench 20, a mounting frame 42 mounted on the fixing block 41, a fixing frame 43 mounted inside the mounting frame 42, and a connecting plate 44 mounted on the fixing frame 43. One end of the connecting plate 44 is located outside the baffle 21 and rotatably mounted inside the fixing frame 43, while the other end is located inside the baffle 21 and has a fixing pressure rod 45 at its end. The mounting frame 42 extends outward from the baffle 21 and rotatably mounts a clamping cylinder 46. A rotating frame 47 is hinged to the middle of the connecting plate 44, and the end of the rotating frame 47 away from the connecting plate 44 is hinged to the piston rod end of the clamping cylinder 46. The piston rod of the clamping cylinder 46 pulls the rotating frame 47, causing the connecting plate 44 to rotate around the axis between it and the fixed frame 43, thereby driving the fixing rod 45 at the end of the connecting plate 44 to perform downward or upward movements. The base plate 31 of the mudguard fixing fixture 30 has fixing platforms at the positions corresponding to the four sets of fixing components 40. The fixing rod 45 presses against the fixing platforms to fix the mudguard fixing fixture 30.

[0025] A limiting frame 48 is rotatably mounted on the fixed frame 43. The end of the limiting frame 48 away from the fixed frame 43 is hinged to the end of the piston rod of the pressing cylinder 46, and the hinged end of the limiting frame 48, the hinged end of the rotating frame 47, and the end of the piston rod of the pressing cylinder 46 are coaxially hinged. The limiting frame 48 limits the upward range of the pressing cylinder 46 when it drives the fixed pressure rod 45 to move.

[0026] A crossbeam 11 is provided at the top of the cabinet 10. Two sets of sliding beams 12 are slidably arranged along the length of the crossbeam 11. A first electric slide table 13 is arranged horizontally on the sliding beam 12. A sliding seat 14 is fixedly installed on the slide base of the first electric slide table 13. A second electric slide table 15 is arranged vertically on the sliding seat 14. A connecting seat 16 is provided on the slide base of the second electric slide table 15. An automatic rivet gun 17 is fixedly installed on the connecting seat 16. A feeding machine 18 is also provided on the workbench 20 to feed studs to the automatic rivet gun 17. The feeding machine 18 is used in conjunction with the automatic rivet gun 17 to feed studs to the automatic rivet gun 17, ensuring that the automatic rivet gun 17 can continuously and automatically insert studs. The sliding beam 12, the first electric slide 13, the sliding seat 14, the second electric slide 15, and the connecting seat 16 work together to enable the automatic rivet gun 17 to move in the X, Y, and Z axes, thus allowing the automatic rivet gun 17 to move within the entire workbench 20 area. By designing a well-defined movement path, the automatic rivet gun 17 can automatically complete the stud insertion at each point, achieving precise positioning and high work efficiency.

[0027] A control cabinet is installed inside the cabinet 10, below the workbench 20. The control cabinet contains a control device used to control the operation of various moving parts on the cabinet 10. A control panel 19 is installed on one side of the cabinet 10 near the opening. The control panel 19 is connected to the control device, facilitating operation by the operator and improving ease of use.

[0028] The operating principle of the automatic mudguard stud embedding device in this embodiment is as follows: First, the mudguard fixing fixture 30 is placed between two baffles 21. Then, the clamping cylinder 46 is activated to drive the fixing rod 45 to press down on the fixing platform on the bottom plate 31 to fix the mudguard fixing fixture 30. Then, the mudguard assembly is placed on the mudguard fixing fixture 30, and the clamping cylinder 34 is activated to drive the clamping plate 35 and clamping block 36 to press down to fix the mudguard. Finally, the sliding beam 12 slides on the crossbeam 11, the sliding seat 14 slides on the first electric slide table 13, and the connecting seat 16 slides on the second electric slide table 15, driving the automatic rivet gun 17 to move in the three directions of X-axis, Y-axis, and Z-axis. In conjunction with the feeding machine table 18, the studs are conveyed, so that the automatic rivet gun 17 embeds the studs at various points on the mudguard, realizing the automated operation of mudguard stud embedding.
