[0002] During the car decoration and beauty process, a polishing machine is needed to grind the surface of the car through the polishing machine to improve the gloss and finish of the car paint. Although the existing polishing machine is relatively portable, the operator can polish the car surface with a handheld polishing machine. However, when polishing the car roof, due to the height limitation of the operator, it is not possible to polish the roof of the car of different models. It is easy to cause a dead angle during polishing due to insufficient distance, so that the car cannot be fully polished. For this reason, the present application designs a mechanical extension arm for the polishing machine, which can greatly increase the polishing range of the polishing machine. Utility Model Content

[0003] The main purpose of the utility model is to provide a mechanical extension arm for a polishing machine, which can effectively solve the problem that dead angles are easily generated when polishing with a hand-held polishing machine, resulting in incomplete polishing.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A mechanical extension arm for a polishing machine comprises a movable guide rail, a drive box is movably arranged inside the movable guide rail, a slide groove is provided in the drive box, a rising slide bar is arranged inside the slide groove, a hydraulic cylinder is installed on the drive box, the output end of the hydraulic cylinder is fixedly connected to the rising slide bar, a platform is fixedly installed on the upper end of the rising slide bar, a support arm is fixedly installed on the upper surface of the platform, a drive assembly for controlling the polishing position is fixedly installed on the upper end of the support arm, and one side of the drive assembly is connected to an installation assembly for installing the polishing machine.

[0006] Preferably, an expansion seat is fixedly installed at the bottom of the driving box, the expansion seat is slidably matched with the movable guide rail, and auxiliary pulleys are respectively provided on both sides of the expansion seat.

[0007] Preferably, the drive assembly includes an installation slot, which is opened at the upper end of the support arm, and a dual-axis motor is fixedly installed inside the installation slot. A movable limit frame and a support limit frame are respectively fixedly installed on both sides of the support arm, and a counterweight block for balancing the weight of the extension arm is slidably installed inside the support limit frame.

[0008] Preferably, the output ends on both sides of the dual-axis motor are respectively fixedly installed with a first driving screw and a second driving screw, the second driving screw shaft is threadedly provided with a threaded sleeve, a counterweight is fixedly installed on the outside of the threaded sleeve, and the threaded sleeve is slidably arranged inside the support limit frame.

[0009] Preferably, the mounting assembly includes a movable seat, which is slidably mounted inside a movable limit frame, a swing seat is movably mounted on the upper side of the movable seat, a translation seat is fixedly mounted on one side of the swing seat, and a mounting clamp for mounting a polishing machine is arranged inside the translation seat.

[0010] Preferably, a forward and reverse screw rod is rotatably installed inside the translation seat, the rod body of the forward and reverse screw rod is threadably matched with the mounting clamps on both sides, and a knob is fixedly installed at one end of the forward and reverse screw rod.

[0011] Preferably, a matching sleeve is fixedly mounted on the bottom of the movable seat, a screw hole is provided inside the matching sleeve and the screw hole is threadably matched with the first driving screw rod.

[0012] Preferably, a rotating groove is provided inside the movable seat, a gear is rotatably installed inside the rotating groove, a matching tooth groove is provided at the bottom of the swing seat, the matching tooth groove meshes with the gear, a motor is fixedly installed on one side of the movable seat, and the output end of the motor is fixedly connected to the gear.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] (1) By arranging auxiliary pulleys on both sides of the extension seat, the drive box can be moved laterally inside the movable guide rail, so as to make quick position adjustment to facilitate the operation of the polishing machine. In addition, since the polishing machine needs to face cars of different heights, in order to ensure the polishing effect, the height position of the rising slide bar is adjusted by starting the hydraulic cylinder, so that the polishing machine can reach the required roof height. Compared with manual operation by personnel, the present application not only ensures that the polishing machine can polish the roof, but also can install the polishing machine through the extension arm, so that the polishing machine does not need to be hand-held by personnel, which reduces the work intensity.

[0015] (2) By starting the dual-axis motor, the first drive screw and the second drive screw can be rotated synchronously. Since the extension arm is L-shaped, in order to avoid weight offset after the polishing machine is installed, which may cause safety hazards during polishing, the second drive screw is shorter than the first drive screw and the thread pitch of the second drive screw is smaller than the first drive screw. Therefore, when the second drive screw rotates, the counterweight block will slide inside the support limit frame, thereby balancing the weight of the installation component on the other side and improving the stability of the extension arm.

[0016] (3) By starting the dual-axis motor to rotate the first drive screw, the first drive screw is engaged with the screw thread inside the matching sleeve, so that the movable seat can move along the movable limit frame, thereby causing the polishing machine on one side to change position, thereby cooperating with the auxiliary pulley to achieve comprehensive polishing of the car roof, effectively solving the problem of polishing dead angles caused by people holding the polishing machine during polishing.

[0017] (4) The gear can be driven to rotate by starting the motor, and when the gear rotates, it meshes with the gear through the matching tooth groove, and the swing seat is slidably set above the moving seat, so that the position of the swing seat can be moved, and then the swing seat can be precisely adjusted to improve the accuracy of the polishing process. The motor can also rotate forward and reverse, so that the swing seat will swing continuously above the moving seat, so that the polishing machine can perform high-intensity polishing on the current surface. Compared with polishing at a fixed position, the present application can improve the polishing effect through swing polishing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 5 As shown, a mechanical extension arm for a polishing machine includes a movable guide rail 1, a drive box 2 is movably arranged inside the movable guide rail 1, the drive box 2 is provided with a slide groove 205, a rising slide bar 203 is arranged inside the slide groove 205, a hydraulic cylinder 201 is installed on the drive box 2, the output end of the hydraulic cylinder 201 is fixedly connected to the rising slide bar 203, a platform 204 is fixedly installed on the upper end of the rising slide bar 203, a support arm 3 is fixedly installed on the upper surface of the platform 204, a drive component 4 for controlling the polishing position is fixedly installed on the upper end of the support arm 3, and a mounting component 5 for mounting the polishing machine is connected to one side of the drive component 4.

[0026] In this embodiment, an expansion seat 202 is fixedly installed at the bottom of the driving box 2 , the expansion seat 202 is slidably matched with the movable guide rail 1 , and auxiliary pulleys 2021 are respectively provided on both sides of the expansion seat 202 .

[0027] By arranging auxiliary pulleys 2021 on both sides of the extension seat 202, the drive box 2 can be moved laterally inside the movable guide rail 1, so as to perform rapid position adjustment to facilitate the operation of the polishing machine. Moreover, since the polishing machine needs to face cars of different heights, in order to ensure the polishing effect, the height position of the rising slide bar 203 is adjusted by starting the hydraulic cylinder 201, so that the polishing machine can reach the required roof height. Compared with manual operation by personnel, the present application not only ensures that the polishing machine can polish the roof, but also can install the polishing machine through the extension arm, so that there is no need for personnel to hold the polishing machine, thereby reducing the work intensity.

[0028] In this embodiment, the driving component 4 includes an installation groove 401, which is opened at the upper end of the support arm 3. A dual-axis motor 402 is fixedly installed inside the installation groove 401. A movable limit frame 405 and a support limit frame 406 are fixedly installed on both sides of the support arm 3. A counterweight block 408 for balancing the weight of the extension arm is slidably installed inside the support limit frame 406.

[0029] In this embodiment, the first driving screw 403 and the second driving screw 404 are fixedly installed at the output ends on both sides of the dual-axis motor 402, and the second driving screw 404 is threadedly provided with a threaded sleeve 407 on the shaft, and a counterweight block 408 is fixedly installed on the outside of the threaded sleeve 407, and the threaded sleeve 407 is slidably set inside the support limit frame 406.

[0030] By starting the dual-axis motor 402, the first drive screw 403 and the second drive screw 404 can be rotated synchronously. Since the extension arm is L-shaped, in order to avoid weight offset after the polishing machine is installed, which may cause safety hazards during polishing, the second drive screw 404 is shorter than the first drive screw 403, and the thread pitch of the second drive screw 404 is smaller than that of the first drive screw 403. Therefore, when the second drive screw 404 rotates, the counterweight block 408 will slide inside the support limit frame 406, thereby balancing the weight of the installation component 5 on the other side and improving the stability of the extension arm.

[0031] In this embodiment, the installation component 5 includes a movable seat 501, which is slidably installed inside the movable limit frame 405. A swing seat 503 is movably installed on the upper side of the movable seat 501, and a translation seat 509 is fixedly installed on one side of the swing seat 503. An installation clamp 508 for installing the polishing machine is arranged inside the translation seat 509.

[0032] In this embodiment, a forward and reverse screw rod 510 is rotatably installed inside the translation seat 509 , the rod body of the forward and reverse screw rod 510 is threadedly matched with the mounting clamps 508 on both sides, and a knob 511 is fixedly installed at one end of the forward and reverse screw rod 510 .

[0033] When installing the polishing machine, the polishing machine can be set in the middle of the installation clamp 508, and then the knob 511 is turned to drive the forward and reverse screw rods 510 to rotate, and then the forward and reverse screw rods 510 are threadedly matched with the installation clamp 508 to clamp and lock the polishing machine in the middle to complete the fixation of the polishing machine.

[0034] In this embodiment, a matching sleeve 502 is fixedly installed at the bottom of the movable seat 501 . A screw hole is provided inside the matching sleeve 502 and the screw hole is threadedly matched with the first driving screw rod 403 .

[0035] By starting the dual-axis motor 402 to rotate the first driving screw 403, the first driving screw 403 is threadedly engaged with the internal screw hole of the matching sleeve 502, so that the movable seat 501 will move along the movable limit frame 405, so that the position of the polishing machine on one side changes, thereby cooperating with the auxiliary pulley 2021 to achieve comprehensive polishing of the car roof, effectively solving the problem of polishing dead angles caused by people holding the polishing machine during polishing.

[0036] In this embodiment, a rotating groove 505 is opened inside the movable seat 501, and a gear 506 is rotatably installed inside the rotating groove 505. A matching tooth groove 504 is opened at the bottom of the swing seat 503, and the matching tooth groove 504 is meshed with the gear 506. A motor 507 is fixedly installed on one side of the movable seat 501, and the output end of the motor 507 is fixedly connected to the gear 506.

[0037] By starting the motor 507, the gear 506 can be driven to rotate, and when the gear 506 rotates, the tooth groove 504 engages with the gear 506, and the swing seat 503 is slidably set above the moving seat 501, so that the position of the swing seat 503 is moved, and then the swing seat 503 can be precisely adjusted to improve the accuracy of the polishing process, and the motor 507 can also be used to rotate forward and reverse, so that the swing seat 503 will swing continuously above the moving seat 501, so that the polishing machine can perform high-intensity polishing on the current surface. Compared with polishing in a fixed position, the present application can improve the polishing effect through swing polishing.

[0038] The working principle of the mechanical extension arm for polishing machine:

[0039] When in use, first place the polisher in the middle of the mounting clamp 508, then turn the knob 511 to drive the forward and reverse screw rods 510 to rotate, and then make the forward and reverse screw rods 510 threadedly engage with the mounting clamp 508 to clamp and lock the polisher in the middle, thus completing the fixation of the polisher;

[0040] Then, the polishing height is adjusted according to the vehicle model, wherein the height position of the rising slide bar 203 is adjusted by starting the hydraulic cylinder 201, so that the polishing machine can reach the required roof height, and then the polishing machine is started;

[0041] Then, the dual-axis motor 402 is started to rotate the first driving screw 403, so that the first driving screw 403 is threadedly matched with the inner screw hole of the matching sleeve 502, so that the movable seat 501 moves along the movable limit frame 405, so that the position of the polishing machine on one side changes, so as to cooperate with the auxiliary pulley 2021 to achieve comprehensive polishing of the car roof;

[0042] During the polishing process, the motor 507 is rotated forward and reversely, so that the swing seat 503 will swing continuously above the moving seat 501, so that the polishing machine can perform high-intensity polishing on the current surface.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
