Description

Technical Field

[0001] This utility model relates to the field of burr removal technology, specifically to a multi-directional burr removal device for housings. Background Technology

[0002] Motor housings are generally cylindrical thin-walled parts made of cast iron or aluminum alloy. After they are formed into blanks, burrs will inevitably be generated. Burrs are excess waste generated at the edge of the processed material due to the plastic deformation of the material. In order to process the housing in subsequent processes, the burrs need to be removed.

[0003] Motor housings are generally composed of a cylindrical tube and ribbed plates on the outer wall of the cylindrical tube. Due to the small spacing between the ribs, deburring is usually done manually, which is inefficient. In order to improve the efficiency of deburring, a deburring device that can travel along the outer path of the motor housing has emerged. It removes burrs by contacting the edges of the ribs and the spacing between them with a high-speed rotating fine rod. However, the cost is high.

[0004] Based on this, the present invention designs a multi-directional deburring device for the housing to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a multi-directional deburring device for housing.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-directional deburring device for housings includes a lower base, an upper mounting bracket, and a motor housing. A stepper motor is installed inside the lower base, and the output end of the stepper motor rotatably passes through the lower base and is connected to a lower turntable. An upper disc is fixed to the top of the upper mounting bracket. The motor housing is placed on the lower turntable. Two sets of cylinder assemblies are installed at the top of the upper disc. Each cylinder assembly includes two cylinders. A deburring component is installed below each cylinder. The deburring component includes a connecting ring, an outer grinding component, a mounting plate, a rotating motor, and an inner grinding rod. The connecting ring and the mounting plate are fixed to the piston rod end of the cylinder. The outer grinding component is fixed to the inner wall of the connecting ring. The rotating motor is mounted on the mounting plate, and its output shaft rotatably passes through the mounting plate and is connected to the inner grinding rod.

[0008] Furthermore, the upper mounting bracket has three sets and is evenly arranged on the side of the upper disk. The stepper motor rotates in 120-degree steps, and the stroke of the piston rod inside the cylinder is greater than the vertical distance from the top of the motor housing to the bottom of the upper disk.

[0009] Furthermore, the height of the outer grinding part and the inner grinding rod is equal to the height of the motor housing, the inner side of the outer grinding part matches the outer side wall of the motor housing, and the outer side of the inner grinding rod matches the inner wall of the motor housing.

[0010] Furthermore, an L-shaped rod is fixed to the bottom of the side wall of the upper mounting bracket, and a supporting base is fixed to the top of the L-shaped rod. The top of the supporting base and the bottom of the lower turntable are in smooth contact.

[0011] Furthermore, a fixing component is installed between the upper disc and the lower turntable. The fixing component includes a first cylinder, a second cylinder, a fixing plate, and a fixing ring. The first cylinder is installed on the top of the upper disc, the fixing plate is fixed to the end of the piston rod of the first cylinder, and the second cylinder is located on both sides of the center of the mounting plate, with the piston rod inside moving through the mounting plate and the fixing ring.

[0012] Furthermore, the top of the upper disc is provided with a through groove for the rotating motor and the second cylinder to pass through. The diameter of the fixed disc is smaller than the outer diameter of the motor housing and larger than the inner diameter of the motor housing. The fixed disc is larger than the inner diameter of the connecting ring. The outer diameter of the fixed ring is larger than the outer diameter of the motor housing, and the inner diameter of the fixed ring is larger than the inner diameter of the motor housing.

[0013] Furthermore, three sets of centering plates are evenly fixed around the center circumference of the top of the lower turntable, and centering components are installed on the centering plates. The motor housing is placed on the centering plates, and the centering components include a slide rail, a sliding plate, a screw, and a centering bar.

[0014] Furthermore, there are two sets of slide rails that are symmetrically fixed on both sides of the centering plate. The slide plate slides on the slide rails. The screw thread passes through the slide plate on one side of the slide rail. The centering strip is fixed on the slide plate.

[0015] Beneficial effects

[0016] 1. By setting up a deburring component, when the motor housing moves below the deburring component, the cylinder drives the outer grinding component and the inner grinding rod to remove burrs from the outer and inner walls of the motor housing in multiple directions, which improves the efficiency of burr removal from the motor housing, saves costs, and is easy to use.

[0017] 2. By setting up L-shaped rods and supporting base plates, auxiliary support is provided for the lower turntable during rotation, improving its stability; by setting up fixing parts, during the deburring process, the fixing plate moves down through the outer grinding part and contacts the top of the motor housing to press and fix it, and the fixing ring moves down and contacts the top of the motor housing to press and fix it, ensuring the stability of the motor housing during deburring; by setting up a centering plate and centering parts, the screw and the threaded engagement of the sliding plate drive two sets of centering strips to move and contact and push the motor housing, ensuring that it is placed in the center of the centering plate, which facilitates subsequent deburring.

The rotating motor 11 is mounted on the mounting plate 10 and its output shaft rotates through the mounting plate 10 and is connected to the inner grinding rod 12.

[0028] In this embodiment of the utility model, the motor housing 3 to be processed is placed on the lower turntable 5. The lower turntable 5 is driven to rotate by the stepper motor 4, so that the motor housing 3 is below the outer grinding part 9. The upper cylinder 7 is activated to drive the outer grinding part 9 to move down and perform multi-directional contact friction on the outside of the motor housing 3 to remove burrs. After the removal is completed, the outer grinding part 9 is reset, and the stepper motor 4 continues to run, so that the motor housing 3 is below the inner grinding rod 12. The upper cylinder 7 is activated to drive the inner grinding rod 12 into the motor housing 3. The motor 11 is rotated to drive the inner grinding rod 12 to rotate and remove burrs from the inside of the motor housing 3. After the removal is completed, the inner grinding rod 12 is reset, and the motor housing 3 can be removed.

[0029] In this embodiment of the utility model, by setting a deburring component, when the motor housing 3 moves below the deburring component, the cylinder 7 drives the outer grinding component 9 and the inner grinding rod 12 to remove burrs from the outer and inner walls of the motor housing 3 in multiple directions, which improves the efficiency of burr removal from the motor housing 3, saves costs, and is easy to use.

[0030] In one embodiment of this utility model, the upper mounting bracket 2 has three sets and is evenly arranged on the side of the upper disc 6 to improve the stability of the upper disc 6. The stepper motor 4 rotates in 120-degree steps. The extension and retraction stroke of the piston rod inside the cylinder 7 is greater than the vertical distance from the top of the motor housing 3 to the bottom of the upper disc 6. The height of the outer grinding part 9 and the inner grinding rod 12 is equal to the height of the motor housing 3. The inner side of the outer grinding part 9 matches the outer side wall of the motor housing 3, and the outer side of the inner grinding rod 12 matches the inner side wall of the motor housing 3, ensuring that the outer grinding part 9 can cover the outer side wall of the motor housing 3 and the inner grinding rod 12 can cover the inner side wall of the motor housing 3.

The top of the support base 14 is in smooth contact with the bottom of the lower turntable 5, providing auxiliary support for the lower turntable 5 and improving its stability.

[0031] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fixing component is installed between the upper disc 6 and the lower turntable 5. The fixing component includes a first cylinder 15, a second cylinder 16, a fixing plate 17, and a fixing ring 18. The first cylinder 15 is installed at the top of the upper disc 6. The fixing plate 17 is fixed to the end of the piston rod of the first cylinder 15. The diameter of the fixing plate 17 is smaller than the outer diameter of the motor housing 3 and larger than the inner diameter of the motor housing 3. The fixing plate 17 is larger than the inner diameter of the connecting ring 8. The second cylinder 16 is located on both sides of the center of the mounting plate 10, and its internal piston rod moves through the mounting plate 10 and connects to the fixing ring 18. The outer diameter of the fixing ring 18 is larger than the outer diameter of the motor housing 3. The inner diameter of the fixed ring 18 is larger than the inner diameter of the motor housing 3. The top of the upper disc 6 is provided with a through groove 19 for the rotating motor 11 and the second cylinder 16 to pass through. Three sets of centering plates 20 are evenly fixed on the center circumference of the top of the lower disc 5. Centering components are installed on the centering plates 20. The motor housing 3 is placed on the centering plates 20. The centering components include a slide rail 21, a slide plate 22, a screw 23 and a centering bar 24.

[0032] In this embodiment of the invention, during use, the motor housing 3 to be processed is placed on the centering plate 20 on the lower turntable 5. The screw 23 is rotated, and the threaded engagement between the screw 23 and the sliding plate 22 drives the two sets of centering bars 24 to move, contacting the motor housing 3 and ensuring it is placed in the center of the centering plate 20. Then, the screw 23 is reversed to reset the centering bars 24. The stepper motor 4 drives the lower turntable 5 to rotate, positioning the motor housing 3 below the outer grinding piece 9. The first cylinder 15 is activated to drive the fixing plate 17 downwards, passing through the outer grinding piece 9 and contacting the top of the motor housing 3 to press and fix it. Then, the upper cylinder 7 is activated to drive the outer grinding piece 9 downwards, pressing and fixing it. Multi-directional contact friction is performed on the outer side of the motor housing 3 to remove burrs. After the burrs are removed, the outer grinding part 9 and the fixed plate 17 are reset, and the stepper motor 4 continues to run, so that the motor housing 3 is below the inner grinding rod 12. The upper cylinder 7 is started to drive the inner grinding rod 12 into the motor housing 3. Then the second cylinder 16 is started to drive the fixed ring 18 to move down and contact the top of the motor housing 3 to press and fix it.
