This vehicle sill processing fixture has the advantage of conveniently clamping vehicle sills.

[0004] The aforementioned document discloses the following defects in the body door sill processing fixture: the technical solution uses a filter screen to intercept dust during dust removal, and when the dust on the filter screen clogs the holes, it needs to be cleaned manually, which increases the workload.

[0005] Therefore, it can be seen that the existing body door sill processing fixture does not have a structure to prevent filter clogging, and it is necessary to improve the existing shortcomings and provide a new body door sill processing fixture. Utility Model Content

[0006] The purpose of this utility model is to provide a vehicle body door sill processing fixture to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a vehicle body door sill processing fixture, comprising a base plate, a mounting seat fixedly mounted on the upper surface of the base plate, a movable plate slidably connected inside the mounting seat, a clamping assembly installed inside the movable plate, a receiving cylinder mounted on the upper surface of the base plate, a fixing plate fixedly mounted on the inner wall of the receiving cylinder, a dust extraction fan fixedly mounted on the inner wall of the fixing plate, a filter screen fixedly mounted on the inner wall of the receiving cylinder, a through groove opened on one side of the mounting seat, a drive mechanism mounted on one side of the mounting seat, and an auxiliary mechanism provided on the upper surface of the receiving cylinder.

[0009] Furthermore, the driving mechanism includes a fixed housing, a first motor, a lead screw, and a connecting plate. The fixed housing is fixedly installed on one side of the mounting base. The first motor is installed inside the fixed housing. A lead screw is installed at the output end of the first motor. One end of the lead screw is rotatably connected to the inner top of the fixed housing. The connecting plate is threadedly connected to the outer surface of the lead screw. The connecting plate is connected to the movable plate through a through groove.

[0010] Furthermore, the auxiliary mechanism includes a top plate, support tubes, and a vacuum head. The top plate is installed on the upper surface of the receiving cylinder, and two sets of support tubes are fixedly installed on the upper surface of the top plate. A vacuum head is installed at one end of each set of support tubes.

[0011] Furthermore, the auxiliary mechanism also includes a second motor, a drive shaft, and a cleaning brush. The second motor is mounted on the upper surface of the top plate, and the output end of the second motor extends into the interior of the receiving cylinder. The output end of the second motor is fixedly mounted on the drive shaft, and a cleaning brush is mounted on one end of the drive shaft. The cleaning brush abuts against the filter screen.

[0012] Furthermore, the clamping assembly includes a limiting plate, a threaded cylinder, a screw, a turntable, a placement plate, a slide groove, and a clamping plate. The limiting plate is inserted into the interior of the movable plate. A threaded cylinder is fixedly installed on the inner wall of the limiting plate. A screw is threadedly connected to the interior of the threaded cylinder. A turntable is fixedly installed at one end of the screw. A placement plate is fixedly installed at the end of the threaded cylinder away from the turntable. The screw extends into the interior of the placement plate.

[0013] Furthermore, the placement plate has two sets of sliding grooves inside, and the end of the screw away from the turntable is rotatably connected to a clamping plate, which is slidably connected to the two sets of sliding grooves.

[0014] This utility model has the following beneficial effects:

[0015] (1) By starting the second motor, the output end of the second motor drives the drive shaft to rotate, and the drive shaft drives the cleaning brush to rotate. Since the cleaning brush is in contact with the filter screen, the rotation of the cleaning brush will clean the dust adsorbed and blocked on the filter screen, ensuring the air permeability and dust suction efficiency of the filter screen, and avoiding the situation where the filter screen is blocked and needs to be cleaned frequently by hand.

[0016] (2) By starting the first motor, the output end of the first motor drives the lead screw to rotate. Since the lead screw is threadedly connected to the connecting plate and the connecting plate is connected to the movable plate through the through groove, the rotation of the lead screw will cause the connecting plate to move linearly along the lead screw, thereby driving the movable plate to slide inside the mounting base. The movement of the movable plate can drive the clamping component to move, thereby achieving the effect of automatic lifting and lowering, and improving work efficiency.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 4 As shown, this utility model is a vehicle body door sill processing fixture, including a base plate 1, a mounting seat 2 fixedly installed on the upper surface of the base plate 1, a movable plate 3 slidably connected inside the mounting seat 2, a clamping assembly installed inside the movable plate 3, a receiving cylinder 5 installed on the upper surface of the base plate 1, a fixing plate 6 fixedly installed on the inner wall of the receiving cylinder 5, a dust extraction fan 7 fixedly installed on the inner wall of the fixing plate 6, a filter screen 8 fixedly installed on the inner wall of the receiving cylinder 5, a through groove 201 opened on one side of the mounting seat 2, a drive mechanism 4 installed on one side of the mounting seat 2, and an auxiliary mechanism 9 provided on the upper surface of the receiving cylinder 5;

[0027] The drive mechanism 4 includes a fixed housing 401, a first motor 402, a lead screw 403, and a connecting plate 404. The fixed housing 401 is fixedly installed on one side of the mounting base 2. The first motor 402 is installed inside the fixed housing 401. The lead screw 403 is installed at the output end of the first motor 402. One end of the lead screw 403 is rotatably connected to the inner top of the fixed housing 401. The connecting plate 404 is threadedly connected to the outer surface of the lead screw 403. The connecting plate 404 is connected to the movable plate 3 through a through groove 201.

[0028] The auxiliary mechanism 9 includes a top plate 901, a support tube 902 and a vacuum head 903. The top plate 901 is installed on the upper surface of the container cylinder 5. Two sets of support tubes 902 are fixedly installed on the upper surface of the top plate 901. A vacuum head 903 is installed at one end of each set of support tubes 902.

[0029] The auxiliary mechanism 9 also includes a second motor 904, a drive shaft 905, and a cleaning brush 906. The second motor 904 is mounted on the upper surface of the top plate 901. The output end of the second motor 904 extends into the interior of the receiving cylinder 5. The output end of the second motor 904 is fixedly mounted with the drive shaft 905. The cleaning brush 906 is mounted on one end of the drive shaft 905. The cleaning brush 906 abuts against the filter screen 8.

[0030] The clamping assembly includes a limiting plate 10, a threaded cylinder 11, a screw 12, a turntable 13, a placement plate 14, a slide 15, and a clamping plate 16. The limiting plate 10 is inserted into the interior of the movable plate 3. The threaded cylinder 11 is fixedly installed on the inner wall of the limiting plate 10. The screw 12 is threadedly connected to the interior of the threaded cylinder 11. The turntable 13 is fixedly installed at one end of the screw 12. The placement plate 14 is fixedly installed at the end of the threaded cylinder 11 away from the turntable 13. The screw 12 extends into the interior of the placement plate 14.

[0031] The placement plate 14 has two sets of sliding grooves 15 inside. The end of the screw 12 away from the turntable 13 is rotatably connected to the clamping plate 16, and the clamping plate 16 and the two sets of sliding grooves 15 are slidably connected.

[0032] In use, first place the vehicle door frame inside the placement plate 14. Then, by turning the turntable 13, the turntable 13 drives the screw 12 to rotate inside the threaded cylinder 11. Due to the threaded connection between the screw 12 and the threaded cylinder 11, and because the clamping plate 16 is confined within the slide groove 15 of the placement plate 14 and can only slide linearly, the rotation of the screw 12 will cause the clamping plate 16 to move within the slide groove 15. By rotating the turntable 13 to move the clamping plate 16 closer to or further away from the other side of the placement plate 14, the vehicle door frame can be clamped, and then subsequent work can be performed.

[0033] When the height of the clamping assembly needs to be adjusted, the first motor 402 starts, and the output end of the first motor 402 drives the lead screw 403 to rotate. Since the lead screw 403 is threadedly connected to the connecting plate 404, and the connecting plate 404 is connected to the movable plate 3 through the through groove 201, the rotation of the lead screw 403 will cause the connecting plate 404 to move linearly along the lead screw 403, thereby driving the movable plate 3 to slide inside the mounting base 2. The movement of the movable plate 3 can drive the clamping assembly to move, thereby completing the effect of automatic lifting and lowering, and improving work efficiency.

[0034] When vacuuming is required, the vacuum fan 7 is started. The vacuum fan 7 generates suction in the container 5. Since the vacuum head 903 is connected to the top plate 901 of the container 5 through the support tube 902, dust and other impurities generated during the processing of the car body door sill will be sucked in by the vacuum head 903. The dust and other impurities will be sucked into the container 5. The filter screen 8 in the container 5 will filter the dust and prevent the dust from being blown out again by the vacuum fan 7.

[0035] When the filter screen 8 is clogged, the second motor 904 is started. The output of the second motor 904 drives the drive shaft 905 to rotate, and the drive shaft 905 drives the cleaning brush 906 to rotate. Since the cleaning brush 906 is in contact with the filter screen 8, the rotation of the cleaning brush 906 will clean the dust adsorbed and clogged on the filter screen 8, ensuring the air permeability and dust collection efficiency of the filter screen 8, and avoiding the situation where the filter screen 8 needs to be cleaned frequently by hand when clogged.

[0036] When the dust collected above the filter screen 8 needs to be cleaned, the dust on the filter screen 8 can be cleaned by removing the connecting bolts that connect the top plate 901 and the receiving cylinder 5.
