[0005] To achieve the above objectives, this utility model provides the following technical solution: a car body grinding device with a protective structure, comprising a protective box, buffer seats fixedly installed at the four corners of the bottom of the protective box, two hinges fixedly installed on one side of the protective box, a common protective door fixedly installed on one side of the two hinges, a handle fixedly installed on one side of the protective door, a collection assembly installed at the bottom inside the protective box, the collection assembly comprising a collection box, a housing fixedly installed on one side of the protective box, a servo motor installed inside the housing, a screw fixedly connected to the output end of the servo motor, a moving block threadedly connected to the outer side of the screw, and a bearing seat installed on the other side of the screw;

[0006] The other side of the bearing housing is fixedly connected to the protective box. A hydraulic pump is fixedly installed at the bottom of the movable block. One end of the hydraulic pump is fixedly connected to a mounting shell. An electric push rod is installed inside the mounting shell. One end of the electric push rod is fixedly connected to a drive motor. The output end of the drive motor is fixedly connected to a grinding disc. An observation window is opened on the top of one side of the protective box. A dust collection hopper is installed on one side of the protective box.

[0011] As a further embodiment of this utility model: a duct is installed on one side of the fan, and a dust filter is fixedly connected to one side of the duct.

[0012] As a further embodiment of this utility model: a movable plate is hinged to the bottom of the gripper near the anti-slip pad via a pin, and the bottom of the movable plate is rotatably connected to the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This car body grinding equipment with a protective structure, by setting up a scale window, a collection box, a filter screen, and a dust filter, allows for a rough observation of the grinding precision through the scale window after the protective door is closed. This enables operators to ensure the stable operation of the equipment on one side of the grinding disc. During the grinding of the car body, the collection box collects and protects the debris, thus protecting the processing environment. Subsequently, the collection box is removed from the protective box by the limiting action of the guide groove. The support of the buffer seat allows the control fan to absorb the dust and impurities generated during grinding through the dust suction bucket. The filter screen prevents debris from entering and clogging the filter screen. The debris is then sent into the dust filter through the air duct. This not only protects the processing environment but also greatly improves the comfort of the processing process.

[0015] 2. This car body grinding equipment with a protective structure, by setting up a concave block, a movable plate, and an electric push rod, first places the car body on the support plate before grinding. The operation of the cylinder is controlled to drive the movement of the concave block. Because the limiting block is limited by the channel, the concave block can move horizontally, thereby pushing the movement of the gripper through the connecting block. The limitation of the movable plate causes the end of the gripper to be pulled downward by the movable plate, thereby pressing down the end of the gripper to clamp the car body. The anti-slip pad can prevent the car body from falling off during grinding. Then, the servo motor is controlled to drive the screw to rotate, thereby enabling the movable block to drive the synchronous movement of the mounting shell. At the same time, the electric push rod is controlled to drive the movement of the drive motor. The slider is limited by the slide groove to provide support for the movement of the drive motor. Finally, the operation of the hydraulic pump causes the grinding disc to grind the car body. Attached Figure Description

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figure 1-5 As shown, this utility model provides a technical solution: a car body grinding device with a protective structure, including a protective box 1, buffer seats 2 are fixedly installed at the four corners of the bottom of the protective box 1, two hinges 3 are fixedly installed on one side of the protective box 1, and the same protective door 4 is fixedly installed on one side of the two hinges 3. A scale window 6 is opened on one side of the protective door 4, and a sealing ring 7 is fixedly connected to the outside of the protective door 4. Because of the scale window 6, the grinding accuracy can be roughly observed through the scale window 6, so that the operator can ensure the stable operation of the equipment on the grinding disc 18 side.

[0024] A handle 5 is fixedly installed on one side of the protective door 4. A collection component 8 is installed on the inner bottom of the protective box 1. The collection component 8 includes a collection box 801. Two protrusions 802 are fixedly installed on the bottom of the collection box 801. A guide groove 803 is provided on the inner bottom of the protective box 1 at the position corresponding to the protrusions 802. By providing the guide groove 803, the guide groove 803 can support and limit the movement of the protrusions 802, so that the collection box 801 can be easily taken out and placed, thereby centrally processing debris and other impurities.

[0025] A housing 9 is fixedly installed on one side of the protective box 1. A servo motor 10 is installed inside the housing 9. A screw 11 is fixedly connected to the output end of the servo motor 10. A moving block 12 is threadedly connected to the outer side of the screw 11. A bearing seat 13 is installed on the other side of the screw 11. The other side of the bearing seat 13 is fixedly connected to the protective box 1. A hydraulic pump 14 is fixedly installed at the bottom of the moving block 12. A mounting shell 15 is fixedly connected to one end of the hydraulic pump 14. An electric push rod 16 is installed inside the mounting shell 15. A drive motor 17 is fixedly connected to one end of the electric push rod 16. Sliders 19 are fixedly installed on both sides of the drive motor 17. A groove 20 is provided on the mounting shell 15 at the position corresponding to the slider 19. By providing the groove 20, the electric push rod 16 is controlled to drive the drive motor 17 to move. The slider 19 can provide support for the movement of the drive motor 17 by the limit of the groove 20, thereby facilitating the control of the drive motor 17 to drive the grinding disc 18 to move.

[0026] The output end of the drive motor 17 is fixedly connected to the grinding disc 18. An observation window 21 is provided on the top of one side of the protective box 1. A dust collection hopper 22 is installed on one side of the protective box 1. A filter screen 23 is provided inside the protective box 1 at the position corresponding to the dust collection hopper 22. A fan 24 is installed at one end of the dust collection hopper 22. An air duct 25 is installed on one side of the fan 24. A dust filter 26 is fixedly connected to one side of the air duct 25. By providing a dust filter 26, the fan 24 is controlled to absorb the dust and impurities generated by grinding through the dust collection hopper 22. The filter screen 23 can prevent debris from entering and clogging. Then, it is sent into the dust filter 26 through the air duct 25 to ensure the comfort of the working environment.

[0027] Two clamping assemblies 27 are fixedly installed on both sides of the inner side of the protective box 1. Each clamping assembly 27 includes a fixing block 2701. A support plate 2702 is fixedly installed on one side of the fixing block 2701. A channel 2703 is opened on the top of the support plate 2702. A limit block 2704 is slidably connected within the channel 2703. A recess 2705 is fixedly installed on the top of the limit block 2704. A cylinder 2706 is fixedly connected to one side of the recess 2705. One side of the cylinder 2706 is fixedly connected to the fixing block 2701. A connecting block 2707 is fixedly installed on the top of the recess 2705. A gripper 2708 is hinged to the top of the connecting block 2707 via a pin. A non-slip pad 2709 is fixedly connected to one side of the claw 2708. A movable plate 2710 is hinged to the bottom of the claw 2708 near the non-slip pad 2709 via a pin. The bottom of the movable plate 2710 is rotatably connected to the support plate 2702. By providing the movable plate 2710, the control cylinder 2706 drives the movement of the concave block 2705, so that the claw 2708 can rotate through the limit of the connecting block 2707, thereby opening and closing one end of the claw 2708. With the support of the movable plate 2710, when the concave block 2705 moves outward, the movable plate 2710 is subjected to a downward component force, which drives the claw 2708 to clamp the car body.

[0028] The working principle of this utility model is as follows:

[0029] Before the polishing operation, the car body is placed on the support plate 2702. The operation of the control cylinder 2706 causes the concave block 2705 to move. The channel 2703 limits the limit block 2704, allowing the concave block 2705 to push the gripper 2708 through the connecting block 2707. The restriction of the movable plate 2710 causes the end of the gripper 2708 to be pulled downward by the movable plate 2710, thereby pressing down the end of the gripper 2708 to clamp the car body. The anti-slip pad 2709 can prevent the car body from falling off during polishing. Then, the protective door 4 is closed, and the polishing accuracy can be roughly observed through the scale window 6. Then, the servo motor 10 is controlled to drive the screw 11 to rotate. The screw 11, supported by the bearing seat 13, can drive the moving block 12, so that the moving block 12 can move synchronously. The movement of the mounting housing 15 is driven, and the electric push rod 16 is controlled to drive the movement of the drive motor 17. The slider 19, which is limited by the slide groove 20, provides support for the movement of the drive motor 17. Finally, the operation of the hydraulic pump 14 is controlled to lower the grinding disc 18 to grind the car body. During the grinding of the car body, the falling debris is collected by the collection box 801, and the collection box 801 is removed from the protective box 1 by the limiting effect of the guide groove 803 on the protrusion 802. At the same time, the support of the buffer seat 2 enables the control of the fan 24 to absorb the dust and impurities generated during grinding through the dust suction box 22. The filter screen 23 can prevent debris from entering and clogging. Then, it is sent into the dust filter 26 through the air duct 25, which can effectively protect the working environment.
